Definitions
- a photoelectric sensor positioned adjacent an edge of the ribbon, senses any skew and in response signals a tracking device which axially moves one of the-mandrels to overcome the skew.
- the tracking device includes a movable shaft having a series of teeth thereon which mesh with the teeth of a gear rotatable in either direction by a reversible motor in response to the output of the sensor.
- a pair of sensors are used. They cause the tracking device to move the mandrel so that the ribbon alternately tracks along two paths spaced apart a distance equal to the distance the document is shuttled.
- the ribbon preferably tracks along two paths. In this case, the distance between the two paths is equal to one-half the distance between adjacent columns so that those areas of the ribbon which would normally always be located at the spaces between the columns are used.
- This invention relates to printing and, more particularly, to feeding a wide-web inking ribbon past the print line of an on-the-fly printer.
- High speed on-the-fly printers have been developed to print the rapidly generated output information of data processing apparatus.
- print hammers strike the document being printed upon and an inking ribbon against type characters on a type carrier (such as a drum or chain) moving at high speed in back of the document.
- Activation of the hammers is timed with respect to the movement of the type carrier such that selected type characters are impacted.
- the document being printed upon is successively advanced past the print line (i.e., the imaginary line at which characters are printed) after each line is printed to present another line to the hammers.
- the inking ribbon for many of these printers is of the wide-web variety in which the ribbons width extends parallel to the print line and the ribbon is moved in its longitudinal direction past the print line to present different areas of the ribbon to the hammers. lt thereby provides a new supply of ink for each line.
- the ribbon is generally fed between a pair of mandrels in alternate directions.
- the ribbons large width, it has a tendency to deviate from a straight path or skew between the two mandrels. Since the ribbon must pass across all the columns to be printed at the print line and since the ribbon must remain unwrinkled, such skew is obviously a problem.
- the moving type carrier i.e., the type drum
- the moving type carrier presents type characters at the print line to a first group of columns in the line being printed. These columns are printed and then the document is moved or shuttled along the print line to present a second group of columns in the line being printed to the type characters on the carrier and these columns are printed.
- the type characters are presented to the document at alternate columns and the document is shuttled a distance equal to the width of one column; thus, each line is printed in two steps. Since printing occurs only at the alternate columns where the moving type-"carrier presents its type characters, the wide-web inking ribbon is only used at these locations. Those places on the ribbon which are not adjacent the type characters on the carrier are not used and some of the ribbon is wasted.
- a method and apparatus are provided for feeding a wide-web ribbon in an onthe-fly printer.
- the ribbon is fed in alternate directions between two mandrels detachably mounted in the printer so that their positions may be interchanged and the locations of the left and right portions of the ribbon reversed.
- the mandrels'positions are interchanged allowing the locations of the left and right portions of the ribbon to be reversed. This extends the ribbons life since it allows the previously unused portion of the ribbon to be utilized.
- the invention also provides for maximum use of a wide-web inking ribbon in the usual type of on-the-fly printer which presents type characters to all the columns of each line without moving the document.
- FIG. 1 is a simplified isometric view of an on-the-fly drum printer adapted to utilize a preferred embodiment of the ribbon feed.
- FIG. 5 is a view showing the sensor assembly for ascertaining skew in the ribbon.
- FIG. 1 shows an on-the-fly printer having a print drum it 1 with type characters (not shown) on its periphery.
- the drum 1 is mounted on a shaft 2 and rotated at a constant speed by a motor 4.
- the document 3 being printed upon is stepped upwardly by a pair of schematically illustrated conventional paper feed tractors 5 which engage edge perforations 3a in the document 3.
- the document 3 is stepped after each line is printed so that the succeeding line may be printed.
- a bank of print hammers 7 is positioned adjacent the drum 1 and the document 3 passes between the bank of hammers 7 and drum 1. These hammers 7 may consist of any of the variety used in on-the-fly impact printing.
- a circular code disc 11 of conventional construction is mounted on shaft 2 and rotates with the drum 1.
- the code disc 11 contains radial rows of coded apertures 1 1a representing the characters onthe drum 1.
- Light from a light source 12 is passed through these apertures 11a in code disc to a photosensing device 14 which provides coded signals to the control circuits 16 controlling the printer.
- the characters to be printed are also represented by coded electrical signals fed to the control circuits 16 on data input line 18. These signals are compared with the signals from the and photosensing device, 14 and the hammers 7 are energized by the circuit 16 to print the type characters on the drum 1 which correspond to the input characters received on line 18.
- the upper 9a and lower 9b rolls of ribbon 9 are wound on hollow cylindrical mandrels 15a and 15b mounted within the yoke 13 with each end of the ribbon 9 connected to one of the mandrels 15a or 15b.
- the opposite ends of each mandrel 15a or 15b are engaged by a pair of caps 17a, 17b and 170 and 17d.
- the caps 17a, 17b, 17c, 17d have annular tapering portions 19a 19b, 19c and 19d which fit within the ends of the mandrels 15a and 15b and circular flanges 21a 21b, 21c and 21d abutting the mandrels ends.
- a finger 43 and groove 45 are provided to drivingly engage the two.
- the finger 43 is located on the inner surface of the caps hollow inner section 35 and slidably fits into the groove 45 which is provided in the shaft 25a. This allows the cap 17a at the right end of the upper mandrel 15a to be driven by the driving means 27 In many data processing applications, only those columns at the beginning of each line at the left side of the document 3 are printed.
- the invention allows the positions of the mandrels 15a and 15b to be interchanged such that the left and right portions of the ribbon 9 reverse their positions.
- Both mandrels 15a and 15b may be detached from the printer and the upper mandrel 15a engaged by those caps previously engaging the lower mandrel 15b and the lower mandrel 15b engaged by those caps previously engaging the upper mandrel 15a.
- the mandrels 15a and 15b are also turned around so that their left ends exchange positions with their right ends.
- the portion of the ribbon 9 previously on the left in FIG 2 becomes placed on the right.
- the mandrels 15a and 15b are engaged by the caps 17a, 17b, 17c and 17d in he same manner as previously described.
- notches 47 are placed at the left ends of the mandrels 15a and 15b shown in FIG 2 so that when the mandrels 15a and 15b are turned around they may be engaged by the teeth 23a and 23b on the right caps 17a and 17c.
- the unused portion of the ribbon 9 previously on the right is now on the left. It may now be used for printing in the columns at the beginning of the lines being printed at the left of the document 3.
- the ribbon 9 is fed onto one mandrel 15a or 15b and then reversed and wound on the other mandrel 15a or 15b by the action of driving means 27.
- This process of ribbon feeding in alternate directions continues during printing operations.
- Numerous methods and apparatus are known for reversing the direction of ribbon feed and the specific apparatus employed is not relevant to an understanding of the present invention.
- the apparatus shown and described in U.S. Pat No. 3,266,745 issued to W.Y. Benson on Aug. 16, 1966 may be employed to drive and reverse the ribbon.
- the driving means 27 shown in FIG. 2 of the instant specification may be constructed as illustrated by the arrangement of motor 36 drive shafts 6 and 8 and the interconnecting drive elements including the clutches 16-20-42 and 14-18-40 and relay 82 as shown in FIG. 1 of the cited patent.
- the left portion of the yoke 13 has mounted thereon an assembly 147 for sensing the edge of the ribbon 9 as it moves between the mandrels 15a and 15b.
- the assembly 147 is shown in FIG 5 and comprises a pair of photodiodes D1 and D2 (schematically illustrated) which are set within a plastic case 51.
- the case 51 has a slot 51a within which the left edge of the ribbon 9 rides.
- Aligned with the photodiodes D1 and D2 are a pair of light elements L1 and L2 (schematically illustrated), each of which is adapted to direct light onto an aligned photodiode D1 or D2.
- Light passes from the light elements L1 and L2 through he slot 51a onto the associated photodiodes'Dl and D2. The latter provide, an electrical signal indicative of the position of the ribbon 9.
- the upper mandrel 15a In response to the photodiode D1 or D2, the upper mandrel 15a is positioned axially to correct and overcome existing skew.
- the state of the photodiode D1 or D2 determines the direction the upper mandrel 15a should be moved. If the ribbon 9, as sensed by the photodiode D1 or D2, is skewed to the left, the upper mandrel 15a is moved to the left to overcome the skew. Conversely, the upper mandrel 15a is moved to the right to overcome skew causing the edge of the ribbon 9 to be to the right of the photodiode D1 or D2.
- the tracking device for axially moving the upper mandrel 15a in this manner in response to the photodiode D1 or D2 is shown in FIGS 2, 3, and 4.
- the left end of shaft 310 is mounted within a housing member 55 secured to the left part of the yoke 13.
- the shaft 31a is slidably supported within housing 55 by a pair of bushings 57a and 57b, At its right end, the shaft 31a rotatably supports the cap 17b as previously described.
- the cap 17a engaging the right end of the upper mandrel 15a is biased toward the upper mandrel 15a by a spring 39 and thus forces the upper mandrel 15a toward the left so that its left end engages the left cap 17b.
- the shaft 31a When the shaft 31a is moved, it will displace the upper mandrel 15a axially. This is done in response to signals from one of the photodiodes D1 and D2 previously described in connection with FIG 5.
- the motor 65 is adapted to move shaft 31a both with and against the bias of spring 39.
- Spring 39 continually forces the upper mandrel 15a and shaft 31a toward the left. This force can cause unnecessary stresses in the motor 65.
- another spring 76 is provided at the left end of the housing 55 to bias the shaft 31a toward the right. The spring 76 is chosen so that it substantially nullifies and counterbalances the force from spring 39.
- one end of the spring 76 bears against the shaft 31a within a recess 77 located at the shafts left end.
- the other end of the spring 76 bears against the inside surface of a hollow member 79 which is mounted on the left end of housing 55 with fasteners 81.
- the member 79 comprises an annular portion 80 which is closed and shaped at its left end (as seen in FIG 2) to maintain the left end of the spring 76 in place.
- Fasteners 81 secure the hollow member 79 to housing 55 by projecting through a circular flange 82 integral with the annular portion 80 of hollow member 79.
- a cover plate 83 is provided around housing 55 for protecting the tracking assembly.
- FIG. 6 illustrates the operation of a shuttle printer and a method for feeding a ribbon 209 according to the invention in such a printer is shown and described in detail in U.S. Pat. No. 3,313,390 issued to R.H. Curtiss on April 11, 1967.
- the rotating type drum 200 in the shuttle printer schematically illustrated in FIG 6 has spaced fonts 201 located at alternate columns of the line to be printed on the document 203.
- the columns on the document 203 which are aligned with the fonts 201 are printed; the position of the document 203 at this time is indicated at the letter in FIG. 6. After these columns are printed the document 203 is shuttled or moved along the print line in the direction of the arrow designated b.
- the ribbon 209 on alternate passes is shifted along the print line in the directions of the arrow designated e. This is accomplished by alternate use of the photodiodes D1 and D2 mounted adjacent an edge of the ribbon 209, in the manner shown in FIG. 5 and discussed above. As previously noted, only one photodiode D1 or D2 is used for ribbon tracking at a time. When one photodiode D1 or D2 is used, the ribbon 209 will track along one path; when the other photodiode D1 or D2 is being utilized, the ribbon 209 tracks upon a different path.
- the ribbon 209 may be made to track along two paths with the usual type of on-the-fly printer to achieve maximum ribbon use. With this type of printer, type characters are simultaneously presented to all the columns in the line being printed and the type characters on the drum 1 are not spaced as shown with the shuttle printer in FIG. 6.
- the ribbon feed of the invention operates in the same manner as just previously described in reference to the shuttle printer. However, the photodiodes, D1 and D2, (and their aligned light elements L1 and L2) are spaced apart a distance equal to one-half the center-to-center distance between adjacent columns. This causes the ribbon 209 to track along two paths spaced apart by this distance and utilizes the ink in the ribbon 209 normally contained in the space between columns when the ribbon 209 tracks along only one path.
- FIG. 7 is a schematic logic diagram of a control circuit which may be used with the ribbon feed of the invention.
- the elements of diagram operate in a conventional manner on a binary voltage level basis wherein the inputs to the elements and the outputs therefrom always exist at either of two discreet voltage levels the positive voltage level or the negative voltage level of the system.
- the outputs of photodiodes D1 and D2 are fed to a circuit 84 for selecting which of these outputs is to be used for ribbon tracking. As previously noted, only one of the photodiodes D1 or D2 are used at a time.
- the photodiodes outputs are suitably amplified by amplifiers 85a and 85b and fed to AND gates 87 and 89.
- AND gates 87 and 89 are well known circuit elements which provide a positive output voltage only when all input lines exist at the positive level.
- the control and choice of photodiodes D1 and D2 is effected by a switch means such as a flip-flop 91 acting in conjunction with the AND gates 87 and 89.
- the flip-flop 91 is a well known bistable logic circuit element.
- Each positive signal at its T input causes its 1 output to go positive and stay positive while simultaneously its 0 output goes negative and stays negative (assuming that the 1 output was initially negative and the 0 output initially positive). Conversely, a succeeding positive signal at its T input will cause its 1 output to go negative and stay negative while simultaneously its output goes positive and stays positive.
- the outputs of flip-flop 91 are each connected to one of the AND gates 87 or 89 as conditioning inputs. Thus, only one of the AND gates 87 or 89 will pass the amplified output of a photodiode D1 or D2 at a particular time (the particular AND gate 87 or 89 depending on which output of flip-flop 91 is positive).
- Such an input signal may be derived from a ribbon reverse apparatus such as those previously referred to in which an electrical signal is provided each time the ribbon 9 (FIG. 1) becomes essentially completely wound on one'of the mandrels a and 15b.
- a signal may be derived with suitable impedance buffering and amplification from the circuit of relay winding 86 shown in FIG. 1 of the previously cited Pat No. 3,266,745. This signal may be used to trigger and change the state of flip-flop 91.
- the flip-flop 91 is triggered by a signal from the ribbon reverse apparatus only when the ribbon 9 becomes essentially all wound on the upper mandrel 15a.
- the state of the flip-flop 91 is periodically changed to thereby alternately use the outputs from photodiodes D1 and D2.
- the tracking assembly moves the upper mandrel 1521 (FIG. 2) and ribbon 9 so that the ribbon 9 tracks on a different path.
- OR gate 93 is another well known logic circuit element. It provides a positive level output only when one or more of its input lines is at the positive level.
- the output of OR gate 93 provides the output signal from the photodiode selecting circuit 84.
- This output is fed to a tracking circuit 95 for moving the shaft 31a shown in FIG 2.
- the shaft 31a is moved by a reversible motor 65.
- the motor 65 has two inputs which operate to drive it and move the shaft 31a in either direction. Because the motor 65 is being controlled by a logic circuit, a pair of driving circuits 97 and 99 are required at the motors inputs. The voltage levels used in logic circuits are relatively low and the driving circuits 97 and 99 are required to connect the low output of the logic elements to a sufficiently high voltage to control the motor 65.
- An inverter 101 is provided between the input to the tracking circuit 95 and the driver 97. The input to the tracking circuit 95 is applied directly to the other driver 99.
- the inverter 101 provides an output level which is always opposite to its input level. Thus, if a positive voltage is fed to the tracking circuit 95 it activates driver 99 to drive the motor 65 so that shaft 31a is moved in one direction, i.e., to the right. The positive voltage will not activate driver 97 because inverter 101 will convert the positive voltage to a negative one. Conversely, if a negative voltage is applied to the tracking circuit 95, driver 99 will not be activated. However, this negative voltage will be applied to driver 97 as a positive voltage due to the inverter 101. Driver 97 will thus drive motor 65 to cause it to move the shaft 31a in the other direction, i.e., to the left.
- Whether a positive or negative voltage is applied to the tracing circuit depends on whether the photodiode D1 or D2 being used for tracking is active or inactive. As shown in FIG 5, the photodiode D1 or D2 associated with the path then being tracked by the ribbon 9 will be active and generate a first level signal for the tracking circuit 95 when the ribbon 9 is too far to the right at the sensor assembly 147. This first level signal causes the motor 65 to move the shaft 31a to the right whereby the ribbon will be shifted to the left. Conversely, if the ribbon 9 is too far to the left, the photodiode D1 or D2 will be inactive and a second level signal will be applied to the tracking circuit 95. This causes the motor 65 to move the shaft 31a to the left whereupon the ribbon 9 shifts to the right.
- FIG. 7 also shows a simplified logic circuit 102 by which each of the micro-switches 71a or 71 shuts off motor 65 and the printer itself when contacted by the angle bracket 73 shown in FIG 2.
- the single shot circuit 102 is another well known circuit element; it generates a negative to positive to negative square wave output pulse of fixed duration in response to a negative to positive transition at its input.
- the output pulse of single shot 103 is fed to the printers electronic controls schematically illustrated as block 16in FIG. 1. This shuts off the printer.
- the output of single shot 103 is also fed as an input to another driving circuit for shutting off the motor 65.
- gear 61 mounted on the shaft 63 of motor 65 (FIG. 2) reaches an end of the series of teeth 59 and one of the micro-switches 71a or 71b is closed, the motor 65 is shut off and the printing operation is stopped.
- the ribbon tracking circuit 95 for controlling the motor 65 will respond to the state of photodiode D1.
- the photodiode D1 is mounted adjacent the left edge of the ribbon (FIG. 5) as it moves between the mandrels 15a and 15b.
- the left edge of the ribbon 9 is located directly at the photodiode D1 as shown in FIG 5.
- the resultant first level output signal from the photodiode D1 causes motor 65 to drive mandrel 15a to the right whereupon the ribbon 9 is shifted to the left. This eventually causes the light to be blocked from photodiode D1 and the resultant second level signal therefrom reverses the direction of motor 65 and the ribbon 9 begins shifting to the right.
- the end effect is a hunting" of the left edge of the ribbon 9 back and forth across the face of photodiode Dl as the ribbon 9 feeds past the print line.
- the left edge of the ribbon 9 when being fed in the opposite direction, hunts across the face of photodiode D2 and thus tracks along a path of?- set from the path established, in the manner just v discussed, by photodiode D1.
- the average distance of the offset between the two tracking paths is equal to the distance between the centers of photodiodes D1 and D2.
- the present invention achieves a more complete utilization of the ribbon 9, with resultant increase in ribbon life, in printing systems, such as the shuttle printing system described above briefly and in more detail in the above cited US.
