Description:

This invention relates to a machine for banding frankfurters and other articles and more particularly to an automatic machine which performs one complete cycle of operations each time it is started.

The principal objects of the invention are to provide a machine which will automatically accommodate articles of different sizes, which will not injure articles that are easily broken, which does not waste banding material, which is rapid and efficient in operation and which is generally superior to banding machines heretofore available.

In one aspect of this invention the banding machine is provided with a guide having a curved portion surrounding an opening or eye for the article.to be banded, means for advancing a ribbon of banding material endwise along the guide until it surrounds the opening, means for then holding the end of the ribbon, means for retracting the ribbon to draw it snugly around the article while the end is held as aforesaid, and means for severing the ribbon and sealing the overlapping ends of the band together. Preferably the end of the ribbon is held by pinching it between the article and said guide, and means are provided to hold the article in spaced relation to the guide while the ribbon is being advanced. The holding means preferably comprises springpressed clamps at one or both ends of the aforesaid eye, the clamps being relatively movable to grip the article therebetween and also movable together to shift the article against one side of the eye, thereby to pinch the end of the ribbon.

The aforesaid guide is preferably provided with sides to form a channel for the ribbon. By locating the clamps in close juxtaposition to the ends of the aforesaid eye they may serve as said sides. However the sides are preferably fast to the eye, in which case they are interrupted to permit the article to pinch the end of the ribbon against the bottom of the channel-shaped guide.

In another aspect the invention comprises one roller for advancing the ribbon and another roller for retracting the ribbon, together with means for pressing the ribbon against either roller.

Thus the ribbon may be pressed against the advancing roller long enough to advance the ribbon the predetermined distance and then pressed against the retracting roller to draw the ribbon snugly around the article. By locating a friction device between the two rollers a single device serves to produce a braking action on the ribbon in either direction of movement of the ribbon.

In still another aspect the invention involves unique means for severing the ribbon and sealing together the overlapping ends of the band. This means comprises a spring-pressed plunger for holding the overlapping ends during the severing 6 and sealing operations, the plunger and cutter and sealing device being mounted on a movable head in such manner that in the advance movement of the head the plunger first engages the band, further movement of the head further compressing its spring, the cutter then severs the ribbon and finally the heated sealing device momentarily presses the overlapping ends of the band to soften the adhesive on one of the interengaging faces of the band.

For the purpose of illustration a typical embodiment of the invention is shown in the accompanying drawings in which Fig. 1 is a side view of a banded frankfurter; Fig. 2 is a transverse section of the banded frankfurter; Fig. 3 is a front end elevation of the banding machine with parts broken away; Fig. 4 is a section on line 4-4 of Pig. 3; Fig. 5 is a right-hand side elevation with the right-hand cover removed, showing the parts in idle posit'on between cycles; Fig. 6 is a right-hand side elevation of the gear train; Figs. 7 to 11 inclusive are sections on the correspondingly numbered lines of ig. 5; Fig. 12 is a top plan view of the guide for the label material; Pig. 13 is a right-hand side elevation of the means for feeding a ribbon of label material, showing the parts in the positions which they occupy when the ribbon is being fed forwardly; Fig. 14 is a right-hand side view of the mechanism for clamping the article while it is being banded, the parts being shown in the positions which they occupy after the ribbon of label material has been fully advanced; Fig. 15 is a similar view showing parts in section and showing the parts in the positions which they occupy while the ribbon of label material is being retracted; Fig. 16 is a similar view showing the parts in the positions which they occupy after the ribbon of label material has been drawn snugly around the frankfurter and is about to be cut off and sealed; Fig. 17 is a view similar to Fig. 13 showing the parts in the positions which they occupy after the band'ng operation has been completed but before the article has been released; and Fig. 18 is a section on line 18-18 of Fig. 17 with parts omitted.

The particular embodiment of the invention chosen for the purpose of illustration comprises i5 a base I, a main frame or casing 2 secured to the base by means of screws 3 and left-hand and right-hand covers 4 and 6, the former cover enclosing a motor, reduction gearing and clutch of standard construction and therefore not shown. 0 The frame 2 has a left-hand side wall 7 provided with a flange 8 projecting to the right from the point 9 to the point 9' (Fig. 5), and the frame is spaced from the base throughout most of the length of the base as indicated at 11 in Figs. 3 and 5. Mounted on the under side of the top portion of the flange 8 is an auxiliary frame 12 which is secured by screws extending through openings in the top portion of flange 8 and thence threading into the openings 13 in the auxiliary frame (Fig. 4). The auxiliary frame 12 is provided with a circular opening or eye 14 to receive the article to be banded (Figs. 3 and 13) and at each end of the circular opening the subframe is provided with a narrow flange 15 to provide a guideway for the ribbon B of banding material, the distance between the two flanges being somewhat greater than the width of the ribbon. As shown in Figs. 13, 14, 15, 16, 17 and 18 the flanges 15 do not extend all the way around the opening 14, being omitted at the right-hand lower'side so that the article to be banded may be pressed against the end of the ribbon of label material as shown in Figs. 15, 16 and 17. At the bottom of the opening 14 a slot 16 is provided to receive means for cutting off the ribbon and sealing together the overlapping ends of the band.

As shown in Pigs. 3 and 5 the cover 6 and the wall 7 are provided with openings 17 and 18 In line with the opening 14 in the auxiliary frame 12 to accommodate the projecting ends of the frankfurter, the cover 6 and wall 7 being offset inwardly around the openings 17 and 18. The wall 7 has an extension 10 provided with a projecting flange 20 over which is mounted the cover plate 21 by means of four screws at 19 (Fig. 5), the flange 20 forming a continuation of the flange 8 but being somewhat narrower. The cover plate 21 has a depending portion 21' covering a portion of the main casing 2 (Fig. 5). The plate also has flanges 121 and 122 which meet edge to edge with the flange on cover 6: the flanges 121 and 122 being separated by a space for the ribbon B to feed into the casing from the roll R. The extension 10 has an inwardly projecting boss 22, a'ainst which the main portion of an axle 23 sbuts, the axle being held in place by a nut 24 threaded on the reduced end of the axle which projects through the boss 22. Rotatably mounted on the axle 23 is a drum 25 having a projecting hub to receive the core of the roll R of the banding material, the core fitting tightly over the hub so that the roll and drum are constrained to rotate together on the axle 23. The cover plate 21 is provided with three L-shaped arms 26 (Fig. 3) the outer ends 27 of which project around the periuhery of the roll R. A casting 28 having three arms corresponding to the arms 26 telescopes over the end of the axle 23 and is held in position by means of a set screw 29. Fast to the three arms of the casting 28 are extensions 30 which extend out to and fit into recesses in the ends 27 of the L-shaped arms 26. To place a roll of label material in the device it is necessary merely to loosen the set screw 29 and remove the casting 28 together with the extensions 30 fast thereto.

In passing from the roll R the ribbon B of label material passes under a roller 31, thence over a roll 32 and thence through a guide 33 to the circular channel 14 in the auxiliary frame 12.

As shown in detail in Fig. 12 the ribbon guide 33 has side flanges 34 for attachment to opposite sides of the auxiliary frame 12 by means of screws extendina through the onenings 35 in the flanges.

The holes 35 are so located that the bottom wall of the guide 33 is spaced from the bottom of the subframe 12 far enough to provide a passageway for the label ribbon. At the end of the guide 33 which projects beyond the auxiliary frame 12 the side flanges 34 are folded in as shown at 34'. The bottom of the guide is provided with two openings 36 and 37 to receive pressure rollers hereinafter referred to.

The aforesaid roller 31 is rotatably mounted on the end of an arm 38 fast to a hub 39 which is journaled on an axle 40 mounted on the wall 7 (Figs. 5 and 10). The hub 39 has an extension 39' carrying a pivot pin 41. Threaded through the head 41' of the pivot pin is a hook 42 and pivotally connected to the pin is a link 43. A tension spring 44 has one end connected to the link 43 and the other end connected to a stationary hook 45. A snubbing strap 46 extends around the periphery of the drum 25 with one end connected to hook 42 and the other end fast to the casing at 47. The spring 44 tends to swing the arm 38 in a clockwise direction (Fig. 5) about the pivot 40, thereby tending to cause the strap 46 to produce a snubbing action on the drum 25.

Normally the frictional drag on roll R produces enough tension in ribbon B to hold the arm 38 up against the stop 38' but if the roll R tends to overrun the arm 38 swings downwardly to stop the rotation of the roll R by the aforesaid snubbing action. When the end of the ribbon B is again pulled forward to feed more material to the loop channel 14 the roll 31 is lifted to relieve the snubbing action, thereby permitting the ribbon to feed forwardly.

The mechanism for feeding the label ribbon comprises two rollers 48 and 49 for feeding the ribbon forwardly and backwardly respectively (Figs. 5, 13 and 17), these rollers projecting between the inturned flanges 34' (Fig. 12) opposite the openings 36 and 37 in the ribbon guide 33. The rollers 48 and 49 are fast to gears 72 and 73 respectively and they rotate on axles 69 and 10.

The rollers are driven continuously during each cycle of operation by means of gear 71 on the main drive shaft 58 and intermediate gears 14 and 75 interconnecting gear 71 with gears 72 and 73 (Figs. 6, 7, 9 and 11). Movable into the openings 36 and 37 are two pressure rolls 50 and 51 for pressing the ribbon against one or the other feed roll. The roll 50 is pivotally mounted on an arm 52 fast to a hub 53 which is pivoted on a pin 54 fast to the wall 7 as shown in Fig. 11. Fast to the same hub 53 is another arm 55 on the end of which is pivoted a follower roll 56 riding on a cam 57 fast to the main drive shaft 58, a spring 59 normally holding the roller against the periphery of the cam. The roller 51 is pivoted on an arm 60 which is journaled on the axle 54 independently of the hub 53. A pin 61 is pivotally connected to the arm 60 at 62 with one end projecting loosely through an opening in a lug 63 on the arm 55. A spring 64 bears at its opposite ends against the lug 63 and a shoulder on the pin 61 to urge the arm 60 in a counterclockwise direction about the pivot 54, nuts 65 on the end of the pin limiting the action of the spring.

The cam 57 is provided with a low portion 66, a high portion 67 and an intermediate portion 68. When the roller 56 is on the low portion 66 the spring 59 causes the roller 50 to press the label ribbon against the feed roller 48, thereby to feed the ribbon forwardly as shown in Fig.

13. When the high part 67 of the cam reaches the roller 56 the bell-crank arm 52-55 is swung counterclockwise to retract the pressure roller 50 and to cause the pressure roller 51 to press the label ribbon against the feed roller 49, thereby to reverse the movement of the ribbon. The pressure of the roller 51 is produced by the spring 64, the lug 63 moving away from the nuts 65 after the roller 41 engages the roller 49 or the label strip therebetween. After the ribbon has been drawn snugly around the frankfurter the feed roll 49 slips on the ribbon, the snugness with which the ribbon is drawn around the frankfurter depending upon the adjustment of spring 64. When the intermediate portion 68 of the cam 57 reaches the roller 56 the parts move into the neutral position shown in Fig. 17 where neither of the pressure rollers 50 and 51 is operative.

The mechanism for clamping the frankfurter while being banded comprises a lower clamp 75 and an upper clamp 76 at each end of the opening 14 in the auxiliary frame 12, the lower clamp 75 extending through approximately threequarters of the circumference of the opening and the upper clamp 76 extending through approximately one-quarter of the circumference.

The upper clamps 76 are supported by arms 77 pivotally supported on the auxiliary frame 12 by means of a shaft 78'. The lower clamps 75 are pivotally supported on the same m shaft through the medium of arms 78, the pivotal movement of 'these arms being limited by pins 79 and 80. The upper arms 77 have shoulders 81 and the lower arms 78 have upwardly projecting lugs 82 between which compression springs 83 are mounted on rods 83' in conventional manner to hold the lower arms 78 up against the upper stop pins 79. The arms 77 are fixed on the shaft 78' by pins 84 (Fig. 4) to move in unison and one of the arms 77 has a depending portion 85 which carries a cam follower 86 yieldingly held against t he periphery of a cam 87 by spring 88. When the roller 86 is on the raised portion of the cam 87 the upper clamps 76 are retracted as shown in Figs. 5 and 13, and when the follower is on the low portion of the cam 87 the upper clamps 76 are yieldingly pulled downwardly by the spring 88 against the frankfurter as shown in Figs. 14 to 17 inclusive.

When the lower clamps are in their upper position, with the arms 78 bearing against the upper stop pins 79, the frankfurter is held slightly above the bottom of the opening 14 as shown in Figs. 13 and 14. However when the upper clamps 76 are pulled downwardly they force the lower clamps 75 downwardly, through the medium of the frankfurter, to the position shown in Figs. 15, 16 and 17 where the end of the label 5 ribbon is pinched between the frankfurter and the bottom of the opening 14 in subframe 12.

At the beginning of each cycle of operatiors the label ribbon is advanced to the position shown in Fig. 14 where the end of the ribbon is at 90, 6 the frankfurter being held up by the lower clamps out of the way of the advancing ribbon. After the ribbon has been fully advanced the upper clamps 76 cause the frankfurter to pinch tl-e end of the label strip against the bottom of the 1i opening 14 (Fig. 15) after which the label ribicn is retracted until it is drawn tightly around tbe frankfurter. Then the ribbon is cut off and the overlapping ends of the band sealed together by the following mechanism. 7( Pivotally mounted in the bottom of the subframe 12, by means of a pivot pin 91, is an arm 92 carrying on its outer end a head 93 ccnta'nirg a heating unit 94 and a thermostat 95, a springpressed plunger 96 and a cutter 97 cooperating 75 with a shear plate 98 on the bottom of the subframe 12. The arm 92 carries.a cam follower 99 which is held against the periphery of 'a cam 100 by means of spring 101. When the follower S.99 bears on the low part of the cam 100 the head 93 is retracted to the position shown in Figs. 5 and 13, and when the follower rides up on the raised portion of the cam the head is advanced to the position shown in Figs. 16 and 17. As the head rises the upper end of the plunger 96 first engages the overlapping portion of the band to press it against the underlying end, further upward movement of the head causing the spring to be further compressed. As the head continues to rise the cutter 97 shears off the ribbon as shown in Fig. 16. Further upward movement of the head brings the nose 102 of the head 93 against the overlapping ends of the band, and inasmuch as this nose is heated by the heater 94 the ends are quickly sealed together by thermoplastic adhesive carried by one of the interengaging faces of the band. As shown in Figs. 13, 16, 17 and 18 the nose 102 is recessed to receive the plunger 96, the nose enclosing the end of the plunger on three sides.

Preferably the band is cut off somewhat beyond the sealing location to leave a projecting end (rig. 2) to facilitate removal of the band. -The operation of the device is improved by retarding the movement of the ribbon B with a friction shoe such as shown at 103 in Figs. 5, 8, 13 and 17, which presses the ribbon against the guide 33 between the rollers 48 and 49. As shown in Fig. 8 the shoe is mounted on an arm 104 pivoted at 185 to a support 106 which is held on the casing 7 by means of a nut 107, the shoe being urged against the ribbon by means of a spring 108. By locating the friction shoe between the two feed rollers it functions during movement of the ribbon in both directions.

The operation of the device is controlled by a handle 109 (Fig. 3) which is pivotally mounted at 110 and which is interconnected at its lower end to a clutch control rod 111. By moving the upper end of the rod to the right the lower end is moved to the left thereby tripping the clutch to start one cycle of operations after which the mechanism comes to rest in the position shown in Fig. 5. The h indle 109 projects upwardly 0 through an opening 112 into the recess in wall 1 past the frankfurter opening 14 so that it may be actuated by the hand in the act of inserting the frankfurter in the opening 14.

At the end of each cycle of operations the fol'5 lower 56 is at the beginning of the low portion of the cam 57 (Fig. 5). Thus as soon as the clutch is tripped to start another cycle of operations the label ribbon is advanced by feed roller 48 to the position shown in Fig. 14. While the o upper clamps 76 may start down before the ribbon has come to rest they should not move beyond the position shown in Fig. 14 before the ribbon has come to rest. After the ribbon has been advanced to the Position shown in Fig. 14 the cam 5 follower 56 shifts from the low part 66 to the high part 67 of the cam 57 thereby retracting the pressure roll 50 and causing the pressure roll 51 to press the ribbon against the feed roller 49, thereby to pull the ribbon backwardly and draw ) it snugly around the frankfurter. The downward movement of the clamps 76 is so timed in relation to the movement of the rolls 50 and 51 that the clamps move from the position shown in Fig. 14 to that shown in Fig. 15, after the ad; vancing roll 50 leaves the ribon' and before the re~ -'-=-b r ~r 9P - I tracting roll engages the ribbon, whereby the end of the ribbon is pinched between the frankfurter and guide after the ribbon is fully advanced and before it starts to retract. After the ribbon has been drawn tightly around the frankfurter the cam follower 56 drops to the intermediate portion 68 of the cam 57 thereby moving the pressure rollers 50 and 51 to neutral position where neither one engages the label ribbon. Then the cam 100 lifts the head 93 to sever the ribbon and 1 seal the overlapping ends as aforesaid.

It should be understood that the present disclosure is for the purpose of illustration only and that this invention includes all modifications and equivalents which fall within the scope of the 1 appended claims.
