Definitions
- One method of accomplishing this grouping is to manually count the sheets as they are placed on the stack and then to manually insert a paper tab or other marker at a given count.
- a paper tab or other marker at a given count.
- the speed of many printing presses and similar devices makes accurate counting difficult.
- manual handling of freshly printed material may result in considerable spoilage.
- the advance of the paper strip andhence the length of the tab is thenprimarily determined by the amountof overtravel of the driven roller and the friction of the paper strip. Since this friction varies with the amount of paper remaining on the roll, the type of paper, as well as several other variables, the length of the tab inserted tends to also vary as the roll of paper unwinds and as other variables change. Furthermore, in the Lautfer device the length of the tab inserted cannot be manually adjusted without great difficulty.
- the improved device of the present invention utilizes a motor to drive a similar roller to advance the paper strip directly onto the stack.
- the operating time of the motor determines the length of the tab inserted and can be determined by an adjustable electronic circuit or other suitable means.
- the advance of the paper strip and hence the tab length can be very precisely determined in advance and simply altered as desired by varying the time'during which the motor drives the roller.
- the improved device of the present invention allows this time interval between the insertion of the tab and the cutting of the paper strip to be precisely set atany given value and changed at will. This flexibility then allows the cutting action to occur after any given number of sheets have fallen atop of the strip. Since the number of sheets necessary to retain the tab in the stack varies with the type of paper, the size of the .tab and other variables this ability to adjust this time interval improves the ability of the device to operate in any situation.
- the improved device of the present invention connects the actual counting switch, such as a microswitch located on the arm of the printing press first to a Schmidt Trigger circuit which is then connected to the counter.
- the actual counting switch such as a microswitch located on the arm of the printing press first to a Schmidt Trigger circuit which is then connected to the counter.
- a feed button or switch located on the front of the device causes the feed motor to drive the roller continuously when operated so that the end of the paper strip can be manually laced between the rollers and then automatically advanced completely through the device until the end passes the cutoff knife.
- the button or switch is then released the knife operates and the device is then prepared to begin counting and inserting tabs.
- a tab can be inserted into the stack at any time without disturbing the count by using a feed button or switch to cause the motor to advance the strip of paper.
- FIG. I shows one embodiment of the improved automatic sheet counter and tab in- I serter of the present invention.
- This device can be used with any type of production paper or the like from fine writing paper to mattress cartons and, is compact, streamlined, highly portable and dependable.
- the preferred embodiment is described in relation to counting sheets of paper, no such limitation is intended nor required; the improvements described herein can be used with any similar device for counting any of a variety of stacked articles and segregating them into counted groups.
- a heavy circular base 20 supports the sheet counting and tab inserting mechanism 21, and prevents it from being easily tipped over.
- Attached to the base 20 is a telescopic supporting member 22 which allows the sheet counter to be used with many different machines by simply adjusting the head 24 to any desired height.
- the head 24 is supported on a ball joint connector 26 which facilitates the feeding of tabs at any angle by allowingthe head to tilt and move both laterally and vertically.
- the ball joint connector 26 and the telescopic supporting member 22 together allow the device to be used with practically any device which is stacking paper.
- the movable head 24 which contains the mechanisms for counting and inserting tabs including the electronic circuitry 25.
- the electronic circuitry 25 merely represents the elements shown in FIG. 3 and the operation of the circuitry is described in detail below.
- a portion of the casing 28 ofthe head 24 has been removed so that the feeding mechanism can be clearly seen.
- a roll of suitable tab material 30, such as paper, which may be Bristol board or the like is mounted on a reel 32 and one end is threaded into the head 24. Within the head 24 the tab material 30 passes between two rollers 34 and 36. When one or both of the rollers. in this embodiment roller 36, is driven by a motor 38 the material 30 advances through the head and along a feeding bar 40 which may be of any convenient length.
- the paper 30 then advances past a knife 42 and onto the top of a stack of papers 43. After a given time has elapsed the knife 42 is rotated by the shaft 44 to cut the paper. A solenoid 46 within the head 24 is activated to rotate the shaft 44. A spring 47 biases the knife 42 in the normal position shown in FIG. 2 so that after the paper material 30 has been cut the knife 42 returns to that position.
- the improved device 21 shown in FIGS. 1 and 2 has the distinct advantage of ease in loading a new roll of tab material in that it is unnecessary to open the head 24 to thread the new roll of paper through the device.
- the end of a new roll of paper can be merely inserted between the rollers 34 and 36 and the motor 38 operated until the paper advances past the knife 42 at which time the motor can be shut off and the knife 42 used to remove material extending beyond the knife 42.
- the device 21 is ready to operate and it is only necessary to set the counter and commence operating the machine which is stacking the items being grouped.
- a variety of devices can be used to indicate to the counter 54 that a sheet has been stacked including a microswitch mounted on the reel arm of the stacking device or a photoelectric eye and cell disposed so that each sheet of paper which is stacked momentarily cuts the beam, the light thereby creating an electrical pulse.
- a small switch can be disposed above the stack of sheets 43 so that it is closed or opened by contact with each sheet as it is placed on the stack.
- a microswitch mounted on an arm or in a similar position on the press or stacking device has a number of advantages and is preferred.
- a number of switches, knobs, buttons or the like which can be used to fully control the operation of the device can be mounted.
- the number of sheets to be counted as one group can be set for example on a dial so that the counter will count until that number is reached and then produce a suitable signal which causes the motor 38 to advance the strip 30 and place a tab atop the pile 43.
- the length of the tab can be altered by setting another control mechanism such as a dial which changes the length of time during which the feed motor advances the tab and hence the length of the tab.
- the time between the placing of the tab on the stack 43 and the operation of the knife 42 to cut the paper strip 30 can be altered as desired by operating an exterior control.
- Several other control mechanisms can also be mounted conveniently on the exterior of the head 24.
- FIG. 3 shows a block diagram of the circuit 25 and other elements for performing the counting, feeding and cutoff functions described above for the device shown in FIGS. 1 and 2.
- the stacking of each individual sheet of paper is recorded by the closing or opening of a switch 50, but as mentioned above, any suitable type of switch or device can be used.
- Schmidt Trigger circuit 52 which produces a short electrical pulse of any chosen width which is conveyed to the counter 54 which can be of any suitable type. Since the Schmidt Trigger 52 produces only one output signal for each opening or closing of the switch 50, the device 21 will not continue blindly counting should a malfunction cause the switch 50 to freeze in one position. One pulse only will be produced for each sheet stacked.
- the counter 54 has been preset for example by means of an exterior dial on the head 24 to produce another electrical signal each time the number set to be in one group coincides with the number of accumulated pulses received from the Schmidt Trigger 52.
- This pulse producing action by the counter 54 upon reaching the set number is represented in FIG. 3 by the closing of an internal switch 56.
- the counter 54 then begins to count again, repeating this pulse producing action represented by the closing of switch 56 when the preset count is once again reached.
- Closing switch 56 in turn activates the time circuit 58 resulting in certain electrical connections which cause the electrical motor 38 to operate and to rotate the roller 36 and thereby to advance the paper strip 30 through the device 21 and atop the pile of sheets 43 during a variable time interval.
- the timer circuit 58 abruptly terminates the power to the motor 38 causing it to cease advancing the paper strip 30.
- This variable time interval which in fact determines the length of the marking tab placed atop the pile 43 can for example be determined by setting a variable resistor 62 by a external dial on the head 24 or by any other suitable arrangement.
- Power to the motor 38 may be simply ended to stop the advance of the paper strip 30 or a brake 63 may be activated by electrical connections made by the timer 58 at the end of the variable time interval to stop the motor immediately without coasting.
- a brake considerably improves the uniformity of length of the paper tabs inserted since any overtravel of the motor 38 varies somewhat with the frictional resistance of the paper and hence the tab length varies slightly as the roll of paper shrinks with use.
- variable time interval time delay circuit 64 is activated so that after another variable time delay has elapsed the knife solenoid 46 is activated to rotate the shaft 44 and operate the knife 42 to cut the strip 30. Since the time between the placing of the paper strip 30 atop the pile 43 and the activation of the solenoid 46 determines the number of sheets which will be piled on top of the paper strip 30 before cutting, this time delay of time delay circuit 64 can be set to any given value so that any given number of sheets will be piled on top of the strip 30 before cutting. The number of sheets necessary to hold the tab between the sheets of course varies with the type of paper, length of the tab and several other variables so that the ability to alter this time increases the ability of the device 21 to adapt itself to any given situation.
- the feed switch 70 which merely represents a means of operating the motor 38 without disturbing the counter 54 can be closed at any time to cause the motor to advance the strip 30 atop the stack 43 or to advance the end of a new roll of paper through the device 21.
- the closing of switch 70 then causes the motor 38 to operate and'at the end of that operation which continues as long as the switch 70 remains closed causes the knife solenoid 46 to operate the knife 42. Therefore, a tab can be inserted at any time, for example to note an imperfect sheet or a machine malfunction etc., without altering the count.
- the ease in loading a new roll of material results because the end can be merely threaded between the rollers 34 and 36 manually and the motor operated by closing switch 70 until the strip 30 extends beyond the knife 42.
- a skip count mechanism 72 can be used to remove any number of sheets and then cause the counter 54 to cease counting for that number. Defective sheets or sample sheets can then be removed without disrupting the count of the counter 54.
- a portable apparatus for counting sheets of paper being individually stacked in a pile by a separate stacking device and placing a marking tab atop the pile whenever the number of sheets stacked atop the last marking tab placed is equal to a chosen number comprising:
- a portable casing means for indicating by a first electrical signal each time a sheet of paper is stacked atop said pile; electrical counting means having means to choose said chosen number and electrically connected to said indicating means for counting the number of said first signals indicated by said indicating means and producing a second electrical signal when the count is equal to said chosen number; an electrical motor for advancing a strip of paper so that a portion of said strip is placed atop said pile; an electrical timer circuit mounted in said casing and connected to said counting means for causing said motor to operate during a given time interval determined by said timer circuit after said second signal is produced and having variable electrical means to alter said time interval of motor operation to alter the length of said marking tab; and means for cutting said strip after said portion is placed atop said strip so that a marking tab, at least a portion of which is covered by-sheets of paper subsequently stacked on tab, remains.
