Martin and Charles H. Kretschmer, In, Saginaw, Mich, assignors to M and K Jar Cleaner Corporation, Carrollton, Mich., a corporation of Michigan Filed May 14, 1962, Ser. No. 194,470 10 Claims. (Cl. 53-95) This invention relates to jar capping machines and particularly to certain novel and useful improvements therein. It is a prime object of. the present invention to provide a jar capping machine of improved design which is highly reliable in operation and is capable of receiving jars containing products of various kinds including granular and powder products, exhausting the air therefor picking up a cap, which is so constructed that suction forces will not be applied to the product filled jar and the cap gripping member will not be expanded, unless a cap is picked up by' the initial cap support member.
A further object of the invention is to provide a jar capping machine suitable for use with various caps of the thread-on, press-on, or formed in .place type and constructed from various materials such as aluminum, steel, and suitable plastics.
Another object of the invention is to design a machine incorporating an inflatable member for gripping the cap and securing it in position on the top of the jar.
Still another object of the invention is to provide a machine incorporating an improved inflatable member for gripping jars which not only seals the interior of the evacuating housing but also prevents the jar from turning, even though the jars are slightly irregular, so that mechanical grippers are not required.
A further object of the invention is to provide an improved machine of turret type, employing multiple cap applying heads, which operates rapidly and more efiiciently than machines of known design.
Other objects and advantages of the invention will be pointed out specifically or will become apparent from the following description when it is considered in conjunction with the appended claims and the accompanying drawings, in which:
FIGURE 1 is a fragmentary, sectional elevational view taken through one of the cap applying heads, a typical jar being shown in position within the head just prior to commencement of the capping operation;
FIGURE 2 is a top plan view of the cap gripping element;
FIGURE 3 is an enlarged, sectional view taken line 3-3 of FIGURE 2;
FIGURE 4 is a sectional, side elevational view of a lower section of the machine, but on a reduced scale;
FIGURE 5 is a top plan view of the machine with certain parts omitted and certain parts depicted only schematically in the interests of clarity; and
FIGURE 6 is a sectional view through the cam used in threading the caps on the jars.
Referring now more particularly to the accompanying drawings, wherein we have shown a preferredembodiment of the invention only, a numeral 10 generally indicates a head supporting carriage or turret which is mounted for continuous rotation on a central shaft 11,
on the ice such as shown in Hohl et a1. Patent No. 2,506,363. As in that patent and Hohl et a1. Patent No. 2,338,852 referred to therein, which are incorporated herein by reference, the carrier 10 carries a plurality of jar capping heads generally designated 12 and' revolves in a continuous circumferential path through various stations (see FIGURE 5) at which the machine is supplied with caps and product filled jars, for instance, and the capped jars are removed in a hermetically sealed condition to a conveyor line or the like. A gear 11a (FIG- URE 4) can be staked as at 11b to the carriage 10 in mesh with a gear 110, connected to a suitable drive motor through speed reduction gearing for driving carriage 10 at the desired rate of speed. In FIGURE 5 the incoming conveyor is shown at C and the outgoing conveyor at C, a transfer star wheel for the conveyor C being shown at S and a similar star wheel for the conveyor C being shown at S. The construction is similar to that shown in Barnby Patent No. 2,126,942 except that the curved jar guides G and G are spaced sufficiently to admit a jar cap carrying rotary disc D on which the caps C for the jars J are supplied.
Automatic machinery of this general design is well known and the present invention is concentrated with the construction of the jar capping heads 12 and the control system for supplying air under pressure and applying suction to the jar capping heads 12 rather than to the overall turret type machine on which these heads and their control system are employed. While the invention will be described as though the jar capping head is mounted on a rotary type machine, it is to be understood that the invention is not limited to heads for such machines and it is not necessary to the construction disclosed that they be mounted on a continuously revolving turret or carriage. I
As shown in FIGURE 1, each head 12 includes a main housing generally designated 13 having a flange 14 which is bolted as at 15 to the outer edge of the carriage 10. Mounted on a lower flange portion 16 of the main housing 13, as by bolts 17, is a two-part jar receiving housing of enlarged diameter comprising upper and lower portions 18 and 19, housing section 19 preferably being threaded on the section 18 as at 20 and the housing being sealed by an O-ring 20a provided between the members as shown.
Provided within the housing 13 to journal a shaft 21 is a bushing 21a, which is bolted to the housing 13 as at 21b, and an O-ring seal 21c is also provided as shown. At its lower end the shaft 21 is supported by a bushing 22 which is bolted to the lower end of housing 13 as at 220 and it will be seen that shaft 21 mounts a dependent suction cup member 23 which is received in an opening 24 provided in the lower end of shaft 21. A tubular stud 24a threads into the lower end of the shaft 21 to hold the cup 23 in place. Outer O-ring members 2 5 and 26 seal the bushing 21 and shaft 16.
The shaft 21 is also shouldered at its lower end at 27 to receive a driver plate 28 having a driver pin 29 received in a bore 30 provided in acap gripping member 31. The member 31 is provided with O- ring seals 32, 33, and 34 as shown, and driver plate 28 is provided with an O-ring seal 28a. At its lower end the member 31 is interiorly grooved as at 31:: to accommodate an inflatable cap gripping ring generally designated 35 which, as shown in FIGURE 3, includes relatively thin upper, lower, and exterior walls 35a-35c, respectively, and a relatively thick interior side wall 36. The same construction is apparent in an inflatable ring generally designated 37, provided in an interior groove 38 provided in the housing ring 19 which likewise has relatively thin upper, lower, and exterior walls 37a-37c, respectively, and a relatively thick interior side wall 39. The reason for this construction will later become apparent when the operation of the machine is described.
The shaft 21, which is revolved in a manner to be described to thread a cap C" on the threaded neck a of a typical jar J is also vertically reciprocablein the housing 13. At its upper end a ball-receiving member 41) is fixed on the shaft 21 by a sleeve 41 which is retained in position by a guard member 4-2 which embraces the cam follower ball 43. The ball 43 is maintained up or in engagement with either a steel cam 44 or an inflated cam 44' supported in fixed position on the stationary framework F of the machine in any suitable manner, as in the Pasotti Patent No. 2,614,739. Under the influence of cam 44 the shaft 21 is depressed to lower the member 31 and suction cup 23 in the manner desired during the operation of the machine.
Supported on the upper end of reciprocable and rotatable shaft 21 by a nut 45 is a manifold ring 46 mounted by carriage 10, including a radially extending pin 47 which, when shaft 21 is moved downwardly by cams 44 or 44', rides in a slot 48 in a bifurcated bracket 49 which can be bolted to the periphery of the carriage as at 51 The shaft 21 is maintained in engagement with the cams 44 or 44' by a return spring 51 within housing 13 bearing against a ball bearing race assembly 52 which in turn bears against a flange 21d fixed on the shaft 21 as shown. The spring 51 operates to restore the shaft 21 to the upper position in which it is shown in FIGURE 1 when permitted to do so by cams 44 or 44'.
Provided in shaft 21 in communication with an annular air passage 53 provided in the manifold ring 46 is a vertically extending, axially offset passage 54 whichleads to the annular passage 55 provided in the member 31 between seals 33 and 34. The annular passage 53 in manifold 46 is sealed by rings 56 and 57 as shown. The passage 55 in the member 31 communicates with a passage 58 in member 31 which leads to the passage 59 in cap gripping tube 32.
Also provided in the shaft 21 is a vacuum passage 60,
extending axially in the shaft 21, which leads to the interior of the tubular retainer 24a as shown. Passage 60 could lead axially to the manifold 46 and there connect to line 62, if desired. A control valve generally designated 61 communicates the line 60 with a vacuum source such as a Beach Russ mechanical vacuum pump through line 62 leading to a port 63 in the valve body 64 which has a chamber 65 receiving a reciprocable slide 66. A suction line 67 leading from a port 68 in control member 61 communicates through an opening 69 in the housing section 18 with the space 78 to evacuate air from the jar I when port 68 is in communication with a vacuum source. Also, an air line 71 which communicates with chamber 53 and the cap gripping annular tube 35 leads to a port 72 in the valve body 64. The control member 61 includes an axially extending port 73 in body portion 64 communicating with a vacuum line 74 through a regulator valve 75 and it will be seen that the slide 66 has ports 76 and 77 which are communicable with the ports 68 and 72 when the spool 66 is moved to the left as in FIGURE 1. To permit port 73 to communicate with port 63 at this time the left end of slide 66 can be cut away as at 66a or this may be otherwise accomplished. Valve body 64 further includes a port '78 in alignment with port 68, and a port 79 in alignment with port 72, which communicate with vacuum and air lines 80 and 81, respectively.
A line 82 connects to the jar gripping air tube 37, as shown in FIGURE 1, and leads to an air supply control member 83 which includes a chamber 84 having a slide member 85 therein with two through ports 86 and 87. Also, vent ports 86a and 87a lead through the slide 85 and housing 83 to atmosphere from ports 86b and 87b which communicate with lines 82 and 81 when the slide is in up position as in FIGURE 1. Provided in the lower end of chamber 84 is a spring 88 which normally biases the piston 85 to the upper position where it engages exert a lifting force on the innermost cap C".
with a vertically reciprocable pin 89. The pin 89 may be depressed by a lever arm 90 pivotally mounted as at 91 to a bracket 92 and having a follower roller 93 in engagement with a circular cam 94 supported by a member 95 from the framework F. Air pressure lines 96 and 97 supply the lines 82 and 81, respectively, with air when the piston member 85 is depressed to align the passages 86 and 87 with the respective lines 82 and,81.
Also supported by the frame F by brackets 98 is a stationary, curvilinear rack 99 having gear teeth 1% on a certain portion of its periphery which are engaged by the teeth of the spur gear 181 fixed to a sleeve 102 keyed in any suitable manner to shaft 21 for revolving the shaft 21 to thread the cap C" on the jar J at the proper time. The rack 99 can support cam 44', which differs from cam 44 in that it includes an elastic rubber or rubber-like channel 44a closed by a hard wearing fdisogrin plastic plate 44b and an inflation and deflation valve 440. If the thread on the cap C" does not quite match the thread on the jar, the cap is not forced on by cam 44' because resilient cam 44' is deformable. Moreover, in practice the heads 12 are so closely spaced that there may be three heads 12 under cam 44' at one time. The operation of the end heads 12 will not be disrupted if it is the jar in the middle head of the three upon which the cap will not thread.
The air lines 96 and 97 connect with a ring manifold 103 mounted on the carriage 18 to revolve therewith and particularly to air chambers 104 and 185, respectively, therein. Lines 106 and 106a lead to suitable sources of air pressure such as Gardner Denver compressors or the like and air under a pressure of about 45 p.s.i. is provided to line 97 and under a pressure of about 60 psi to line 96. The manifold 183 also includes vertically through vacuum ports 1G7 and 108 communicating with the lines 74 and 80, respectively. Mounted above the rotating manifold 103 on brackets 109 or the like is a stationary manifold ring 110. The stationary manifold ring 110 includes (FIGURE 5) arcuate slots 112, 113, 114, and 121, as shown, leading through its under surface, and hoses 116, 117, 118 and 123 communicating with them respectively. In addition, there are slots and 120 having vent ports 119 and 122 to atmosphere. The arcuate slot 112 communicates with the vacuum line 74 and the slots 113 and 114 with the vacuum line 80 through ports 107 and 108, respectively.
In the operation of the machine the heads 12 are first passed over the revolving disk D which has caps C" thereon supplied from a chute or in any suitable manner, carrier 10 revolving relatively slowly, of course. As each head 12 approaches the cap supply disk D, cam 44 forces the shaft 21 to descend to bring suction cup 23 into engagement with the innermost cap C on the disk D. At about the time that suction cup 23 is about to engage the cap, the line 74 has moved into communication with the slot 112, which is supplied with vacuum through the line 116, and line 60 is furnished with the vacuum force to Once the suction cup 23 has sealed to the upper surface of cap C", then slide 66 (which has been in outward position) is drawn leftward to the position in which it is shown in FIGURE 1 by the vacuum in line 74 to communicate lines 76 and 77 with lines 80 and 81, respectively. At this time the return spring 51 is permitted by cam 44 to move shaft 21 upwardly toward the position in which it is shown in FIGURE 1. -Each head 12 has a pedestal 125 mounted under it and revolving with the carriage 10 and for each pedestal 125 there is a shaft 126 (FIGURE 4) slidably received by a bearing 12'!" in a lower portion 10a of the carrier 10, each shaft 126 mounting a follower roller 128 which rides on a circular cam track 129 supported by the stationary frame F of the machine. The configuration of cam track 129 is such that the pedestal 125 and jar J tends to follow the cap C" upwardly into the capping head housing 19.
When the suction cup 23 has risen to the upper position in which it is shown in FIGURE 1 and pedestal 125 tubes 35 and 37 so that they grip the jar cap C" and the jar J, respectively. The configuration of these tubes, as demonstrated in FIGURE 3, is important to proper gripping of the cap C" and jar I. With the inner walls 36 and 39 being of substantially greater thickness, the expansion is lateral, rather than upwardly or downwardly. The walls 36 and 39 do not themselves bulge or expand but remain in tight engagement with the surfaces over their vertical lengths. In this way the cap and jar are prevented from lifting and this is particularly important from the standpoint of inflatable ring 37 since, when space 70 is evacuated, atmospheric pressure is tending to push the jar up into the head.
Just after the time that inflatable rubber rings 35 and 37 are expanded into gripping engagement with the cap C" and jar I, respectively, the control slide 66 being in leftward position, slot 113 communicates with the vacuum line 80, with the control slide 66 being at the left as in FIGURE 1. With vacuum line 80 in communication with vacuum line 67, the air is evacuated from the space 70 and the jar J but in such a manner that the contents of the jar I remain undisturbed.
It is important to note that, had the suction cap 23. not picked ,up a cap C", slide 66 would not have been shifted to the left in FIGURE 1 and no air would have been delivered to line 71 to inflate the cap gripping tube 35. This is important from the standpoint that, if the tube 35 is not inflated when no cap C" is in place, the tube cannot be mashed against the threads of the jar neck a or damaged by them when the shaft 21 is revolved. Further, unless a cap C" is picked up by cup 23 the vacuum line 67 is not communicated with the space 70 and the release of vacuum will not disturb the product in the jar J. It is necessary to the operation of the system that the cap C" be in position on the jar I, as shown in FIGURE 1, to prevent this from happening. The arcuate slot 114 may also be connected with a vacuum line 118, or the line 118 could lead to a source of carbon dioxide gas, for instance, if it were desired to gas pack the product.
In any event, at about the time that tube 80 has revolved sufliciently to approach the end clockwisely of slot "114, cams 44 and gear teeth 100 simultaneously revolve and lower shaft.21 to thread the cap C" into secured position on the top of the jar J. Finally, the line 74 comes into communication with the slot 121, which is supplied with air under a pressure of about 1 p.s.i. through the supply hose 123 and restores the slide 66 to the right in FIGURE 1, thereby discommunicating the suction in line 80 with the line 67 and'the air pressure in line 81 with the line 71. Cam 94 permits the spring 88 to return the slide 85 upwardly and thereby tubes 35 and 37 can be simultaneously deflatedthrough vent ports 86a and 87a.
.The slot 120 is open to atmosphere and just before the time that the slide 66 is returned to the out position, atmospheric air is supplied through the line 80 to the line 67 and chamber 70. Also, at about this time, when line 74 is communicating with the slot 115, the vacuum in line 62 and suction cup 23 is released by the pressure of the atmosphere. At this time, with the cap C" securely in position on the jar I, the pedestal 125 is gravity lowered as permitted by the cam 129 until the cap on the jar clears the housing 19 and thence, having completed 'a circuit of the machine, is transferred to the outgoing conveyor C by the star wheel S. In a typical machine there may be twenty-eight heads 12 rotating continuously to cap jars through the cycle of operations described, although less are shown for convenience sake in FIGURE 5.
It is to be understood that the drawings and descriptive matter are in all cases to be interpreted as merely illustrative of the principles of the invention rather than as limiting the same in any way, since it is contemplated that various changes may be made inv the various elements to achieve like results without departing from the spirit of the invention or the scope of the appended claims.
