- the apparatus for making tear strip wrappers is generally designated 124.
- a pushing assembly made in accordance with this invention is generally designated 40.
- the location of an apparatus for aligning a wrapper sheet on a package is generally designated 62.
- the apparatus for detecting and preventing irregular conditions within the wrapping machine is shown in FIGS. 8, 9 and 16 through 21.
- the primary object of the incorporation of the assembly 124 is for producing tear strip wrappers to be placed over packages moving through the machine.
- a cutting means is provided to form a slit configuration including two perforations 32 and 33 on either side of the tear strip material It] and a perforation 31 that crosses the two longitudinal perforations 32 and 33.
- the apparatus assembly 124 is shown in FIG. 2.
- the feeding of the tear strip 10 and the wrapping material web 18 is accomplished in a conventional way.
- the wrapping material web 18 comes off the supply roll 17 and goes under the roll 19, passes upwardly over the roll 22 and downwardly between the rollers 26 and 27.
- the web 18 then passes through the cutting mechanism including the rotating cutter member 29 which is mounted on the rotatable shaft 28.
- rotary knife 29 works in conjunction with the stationary knife 30 to cut sheets from the web 18. The sheets are subsequently used to wrap packages moving through the wrapping machine.
- a more specific description of a sheet feeding and cutting mechanism which may be used in combination with the invention of this application is disclosed in US. Pat. No. 2,837,978.
- a tear strip material is fed downwardly from a supply roll 11 over guide rollers 12 and 13.
- a tension is effected therein before it passes onto the next steps in the process.
- the ribbon 10 passes over a wick 15 which applies solvent that is provided in the reservoir 14.
- the ribbon 10 passes in contact with the heating element 16 for the purpose of evaporating the solvent.
- the ribbon 10 then passes over the pressure roll 22 at which location the tear strip ribbon 10 is glued on top of the wrapping material web 18.
- a pressure roller 22a is used in combination with the roller 22 for the purpose of effecting a joining of the tear strip 10 and web 18.
- the wrapping material 18 may be any type of film material such as polypropylene, cellophane, any similar cellulose acetate material or any equivalent substance.
- the tear strip 10 is made with any similar material. However, the color of the tear strip may be different from that of the wrapping material 18.
- a cutter member 21 which revolves with the shaft 20 is located adjacent the roller 19 in this specific embodiment.
- This cutter member 21 constitutes a first cutting means which is used to make the perforation 31 in the web 18.
- the perforation 31 extends in a direction transverse to the direction of movement for the web 18 and strip 10.
- the strip 10 is located on the web 18 at a position intermediate the perforation 31 when passing between rollers 22 and 22a.
- a second cutting member 24 as shown in FIG. 5 includes cutting edges 36 and 37.
- the cutting member 24 is mounted on the rotatable shaft 23 at a location wherein the cutting edges 36 and 37 cut perforations 32 and 33, respectively, on either side ofthe strip 10.
- the cutting member 25 cuts only through the tape 10 and not through the web 18.
- the cut 34 in this instance is a diagonal cut across the width of the tear strip 10.
- a pair of perforations 32 and 33 cross the transverse perforation 31 and extends longitudinally with respect to the tear strip 10.
- the separation of the cutting members to a first and second cutting means thereby overcomes the disadvantages associated with the use ofa single H-cutting member which is now commonly used in the prior art. That is, a complete, clean cut is assured during the continuous operation of the wrapping machine. It is evident that the location of the various cutting members 21, 24 and 25 may be in different places with respect to each other. The primary limitation is that the cut made by the cutting member 21 forming the perforation 31 must be effected before the tear strip 10 is joined to the web of material 18. It is apparent that the location of the cutting members 21 and 24 with respect to each other may be varied. Obviously, however, other backing rollers would have to be inserted if the cutting members 21 and 24 were located at different points in the apparatus combination.
- the roller 22 is grooved to effect the cuts desired in the web material.
- the structure of the backup rollers 19 and 22 is common in the prior art. They can be made of metal or any other kind of metal material which provides a solid backup for cutting the grooves in the wrapping material web 18.
- the pressure existing between the roller 22 and the cutter member 25 is adjusted so that it will only cut the tear tape 10. if desired, it is possible to reverse the position of the cutter member 24 with respect to the cutter member 25.
- the primary object of the package feed assembly is to insure proper seating of the package in a wrapping machine receiving means.
- the assembly generally designated 40 insures satisfactory application of liquid to the wrapping material for forming a completely sealed and wrapped package.
- the pushing assembly 40 includes a pair of endless chains 41 and a plurality of transverse pusher members 42 and 43.
- the pusher members 42 and 43 are fixedly attached to the chains 41.
- the primary pusher member 42 engages the following side of the package 44.
- the auxiliary pushing member 43 is disposed behind the primary pusher member 42 As the endless chain 41 moves forward, the primary and auxiliary pushing members 42 and 43, respectively, travel in the forward direction behind the package 44 to a wrapper sheet applying station.
- wrapper sheet applying station is not shown in the instant case and does not form a part of this invention. Any conventional manner of applying a wrapper sheet onto a package may be used in combination with the pusher assembly 40. A mechanism for feeding and cutting wrapper sheets to be placed over packages is shown in US. Pat No. 2,837,978.
- the package 44 moves along the support platfonn 73 while being urged to the wrapper sheet applying station.
- the endless chains 41 move along a channel 46.
- the manner in which the endless chains 41 move through the mechanism is another conventional structure heretofore known in the prior art.
- the wrapper sheet material may be cellophane or any other film material.
- Each of the endless chains 41 engage sprockets 59 which are laterally spaced with respect to each other and located adjacent a wrapping machine receiving means.
- the receiving means in this specific embodiment constitutes a turret wheel assembly 53.
- the turret wheel assembly 53 has a plurality of radial pockets as is well known in the prior art. See in particular US. Pat Nos. 3,055,490 and 2,373,655.
- the chain 41 which is used to push packages into the turret wheel assembly 53 is constantly driven.
- the speed of the turret wheel assembly 53 is correlated with the speed of the chain drive 41. This operation involves synchronization to effect the desired packaging.
- Each pocket is formed by the pocket members 54 and 55 which support the package 44 within the turret wheel assembly 53.
- the primary pusher member 42 is effective to urge the package 44 into the receiving means constituted by the pocket members 54 and 55.
- the auxiliary pusher member 43 is allowed to contact the package 44. in this way, pusher member 43 is effective to insure a firm seating of the package 44 in place within the pocket of the turret wheel assembly 53.
- the pocket members 54 and 55 engage the package 44 adjacent one end thereof. Similar pocket members engage the package 44 at the other end thereof.
- a folding platform 56 is disposed between the sets of pocket members forming each pocket in the turret wheel assembly 53.
- the stationary platform member 56 is fixedly mounted onto the wrapping machine with the frame structure 560.
- a stationary liquid applying device 60 is disposed adjacent the receiving means in this specific embodiment.
- the stationary liquid applying device 60 includes a vertically disposed working member 61 which is moistened with either a solvent liquid or an adhesive material.
- a vertically disposed working member 61 which is moistened with either a solvent liquid or an adhesive material.
- the stationary platform 56 provides a place against which the auxiliary pushing member 43 folds the projecting end 58 of the wrapper sheet.
- the endless chains 41 continue to move around the axially aligned and laterally spaced sprockets 59, the auxiliary pusher member 43 exerts an additional force onto the projecting end against the wick 61. This action insures full and complete application of either a solvent material or an adhesive material to the end 58 for subsequent joining of the ends 57 and 58 around the following end of the package 44.
- the step by step operation of the pushing assembly 40 made in accordance with this invention is sequentially shown in FIGS. through 13.
- the wrapper sheet alignment apparatus is generally designated 62 and includes a control roller or roller member 63 rotatably mounted on a shaft 64.
- the primary object of this apparatus is to provide a means for shifting the position of a wrapper sheet that is placed contiguous to a package which is moving through the wrapping machine made in accordance with this invention.
- Many obvious advantages are associated with the incorporation of the wrapper sheet alignment apparatus 62 in the wrapping machine of this invention.
- the longitudinal axis of the roller member 63 extends transversely to the direction of package 44 movement along the support platform 73 of the wrapping machine.
- the shaft 64 is attached to a lever member 65 which pivots about the pin 66.
- the pin 66 also connects the lever arm member 65 to the structure of the support platform 73.
- the lever member 65 pivots in the manner shown by the double headed arrow about the pin 66. This movement is effected through the use of a rod assembly which extends to an operating side of the wrapping machine.
- the rod assembly includes a rod member 67 that is rotatably attached to a pin member 69 with a coupling unit 70.
- the rod 67 is threaded and is inserted into the threaded socket portion of the coupling unit 70.
- a knurled knob 68 is threaded onto the other end of the rod 67 to cause the rod 67 to be adjusted along its longitudinal axis.
- a spring member 72 is disposed between the wrapping machine structure 79 and an abutment 71 located on the rod 67. This spring 72 provides a biasing force which is transmitted to the roller member 63 through the pivoting action of the assembly 62 about pins 66 and 69.
- the control roller 63 is comprised of a resilient material which is effective to frictionally grip the material of the wrapper sheet 75 disposed on the package 44.
- the resilient material of the roller member 63 may be rubber or any other equivalent material.
- a plate member 74 is mounted at a spaced distance from the support platform 73.
- a wrapper sheet 75 is cut from a web 76 of wrapping material through the action of a stationary cutting member 77 and a rotating cutting member 78.
- the specific manner in which the wrapper sheet 75 is cut from the web 76 is well known in the prior art and does not form a part of this invention.
- a sheet feeding and cutting mechanism which may be used in combination with the aligning apparatus ofthis invention is disclosed in US. Pat. No. 2,837,978. When the apparatus of this invention is used with these prior art combinations, the roller member 63 steers the film or web of wrapping material before the knife cuts it off. Such a relationship is shown in FIG. 15.
- a package 44 is moved through the wrapper sheet 75 by the pushing assembly 40 so that the wrapping material is draped across the advanced end and two opposite sides of the package 44.
- the control roller 63 is located right after the package 44 has passed through the sheet 75 so that the frictional gripping of the wrapper 75 by the roller 63 will immediately shift the position of the wrapper sheet on the package 44. Once any wrapper sheet has been folded, it is difficult to shift its position on the package 44.
- the plate member 74 is spaced at an effective distance from the support platform 73 so that when the package 44 passes therebetween, a pressure is exerted between the roller member 63 and one of the sides of the package 44. This pressure is additional to that caused by the weight of the package.
- the spring member 72 provides a tensioning effect when the roller member 63 is pivoted about its central axis by the rod assembly.
- the rotating of the knurled knob 68 effects a control of this pivoting action of the roller member 63 about its central axis.
- the biased movement of the cylindrically shaped roller member 63 about its central axis provides the necessary shifting means to place the wrapper sheet 75 in its desired position with respect to the package 44. That is, the position of the wrapper sheet 75 is skewed with respect to the package 44.
- the apparatus of this invention incorporates both electrical circuit means and mechanical means to provide the necessary functions.
- An electrical circuit for effecting a sequential starting of the machine provides current to the motor (not numbered) which drives the machine. Means is provided for preparing the machine to run.
- a start button is pushed to energize the coil 106.
- the contact relay 107 is turned on and the start button 105 may be released.
- This type of circuit is well known in the prior art and does not form a part of this invention. However, there is a combination of circuits and other devices which does provide novel means for sequentially starting the machine as shown in FIG. 1.
- the motor begins to run and the coil or contact relay 109 is activated. This arms the motor and prepares for the machine to start running.
- the coil 112 Upon the pushing of the start button 111, the coil 112 is energized and the contact or coil relay 113 is activated. This is another lock-in magnetic circuit enabling the release of the start button while enabling the machine to continue its run.
- the coil relay is activated as shown in the parallel circuit below the brake and clutch control circuit.
- a detector used to sense an irregular package feed condition is located.
- the switch 82 represents a clutch mechanism that starts the feed mechanism to operate. Once this feed mechanism is started and is running continuously, the coil 83 is energized. Upon energizing the coil 83, the coil relays 84 and 108 are activated thereby preparing the circuit for starting the motor by way of the magnetic circuit including the button 105, coil 106 and contact relay 107. At the same time that the coil relay 84 is activated by coil 83, the coil relay 114 is activated in the brake and clutch control circuit. For this reason, there is a completed circuit through the brake and clutch control device as soon as the start button 111 is depressed. In other words, the current is allowed to flow through the brake and clutch control circuit thereby empowering the machine to run.
- the timer switch 117 immediately closes thereby providing an additional parallel path for electrical current to flow in the brake and clutch control circuit.
- This specific electrical circuit means including the timer 117, the coil relay 116 and microswitch 86 is used to effect a retracting of a heat sealing means away from a package to avoid burning of the package.
- a turret wheel assembly 53 is used to receive packages.
- a heat sealing means constituted by a heater element 102 in FIGS. 25 and 26 is located adjacent the turret wheel assembly 53 at a heat sealing working station.
- the microswitch 86 as shown in FIGS. 22 and 23 is activated between an open and closed position by virtue of the oscillating cam 92.
- the heating and folding mechanism 87 includes rods 90 and 91 which operate levers 89 and 88, respectively to oscillate the heating element 102 and folding member 103 between the positions shown in FIGS. 25 and 26.
- the heater element 102 and folder member 103 are in the position as shown in FIG. 25.
- the heater element I02 and folder member 103 are in the position as shown in FIG. 26. If, for any reason, the parallel circuit of FIG. 27 including the coil relay 114 and coil relay 115 is deactivated, the parallel line including the timer switch 117, coil relay U6 and microswitch 86 will enable current to be maintained as long as the microswitch 86 remains closed.
- FIG. 24 The manner in which the heater element and folder arm is moved through its mechanical arrangement is shown in FIG. 24.
- the heater arm 89 is fixedly mounted on the shaft 94 and oscillates the heater 102 back and forth.
- the folder arm 88 is coaxially arranged with respect to the shaft 94 and moves the folder arm 96 back and forth.
- This assembly is attached to the frame 93 by virtue of the anchor part 97 and bolt 98.
- Bushings 99 and 100 enable the folder am 96 to oscillate with respect to shaft 94.
- the cam 92 is seen to be fixedly mounted onto the shaft 94 and therefore oscillates with the heater element 102.
- the pusher and detecting assembly generally designated 40 as shown in FIGS. 8 and 9 include a sensing means 49. As a package 44 moves over the roller 49, the member pivots about the pin 50 and opens the circuit by way of the switch means SI. The packages are delivered in a predetermined interval. Synchronized with this predetermined interval is a cam surface 81 that is rotatably mounted in a H relationship. That is, for each cycle of the wrapping machine, the shaft revolves the cam surface 81 one time.
- the cam operates the cam switch 80 which may be located at any desired place on the wrapping machine. In this particular embodiment, it is located on the feed chain drive shaft (not numbered). Its particular location is not important. Its specific function is extremely important.
- the cam surface 81 causes the second switch 80 to open and close in synchronization with the opening and closing of the first switch 51.
- the conveyor chains 41 continue to operate.
- both of the switches 51 and 80 are open during an abnormal package feed condition, the conveyor chains 41 are stopped.
- the chains 4] stop when the machine stops running in this embodiment.
- a typical abnormal package feed condition is shown in FIG. 8 wherein two packages 47 and 48 are fed into the machine at the same time. This causes both switches to be opened as shown in FIG. 21.
- the coil 83 is de-energized thereby de-energizing the coil relay 84 and a coil relay in the circuit of the brake and clutch circuit 85.
- the coil relay 114 is deactivated to stop the running of the machine.
- irregular feed condition detector and the delayed retracting system for the heat sealing means are shown in combination, they may also be used separately.
