2% Claims.

This invention relates to wrapping machines and more particularly to a machine for auto-.

An adhesive is then applied to the lower end of each strip. Upon the engagement of a moving pack with a banding strip, the said strip is caused to be wrapped partially around the product so go' as to engage the upper, the lower and the forward end surfaces thereof and has its adhesive end trailing beyond the rear thereof. A gripper, also positioned. in the path of the moving prodnot, is arranged in such novel manner that upon receiving a product, the said gripper raises the productand turns itsupper face downward over the trailing portion of the band while dragging the outer end of the product over the surface of a feed table. The product is then ejected from the gripper and is moved forward again by means of a. second conveyor. During the latter movement the adhesive end of the strip will adhere 'to the outer surface oi the opposite end portion of the band, and after passing beneath a pressure member, will become sealed. The wrapping of said product now being completed, the same is finally moved to an elevator platform which is adapted to move dovmward a distance equal to the thickness of a product after receiving each product, and upon receiving a certain predetermined number of products, the same are moved in a group to a delivery conveyor or other means by an ejector mechanism.

One objector the invention is to feed a strip of bending material into the path of a moving product, whereby said product will engage the strip and, while moving. will be partially wrapped by same.

Another object is to provide mechanism to a partially wrapped product, is adapted to be manipulated to complete the wrapping of said product.

A further object is to provide a pressure applying means to finally seal an adhesive portion sion into the path of an approaching product. 7

operate a gripper member,'which after receivingof the banding material against another portion thereof after the wrapping of the product is completed.

A still further object is to provide an elevator receiving platform for receiving a plurality of completely wrapped products in a superposed order and means to eject same after a predetermined number are received.

It is alsoan object of the invention to provide a banding machine of generally improved construction, whereby the device will be simple, durable and inexpensive in construction, as well as convenient, practical, serviceable and efficient in its use. g

With the foregoing and other objects in view, which will appear as thedescription proceeds, the'invention resides in the combination and ar rangement of parts, and in the details of construction hereinafter described and claimed, it being understood that various changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit {of the invention.

The preferred embodiment of the invention is upper, lower and forward ends and also showing said product engaged by the gripper, and further showing in broken lines the gripper in an interl mediate position while turning said product over upon a trailing end of the band;

Figure 5 is a diagrammatic view showing the pack turned over and being ejected from the gripper; and

. Figure 6 is a perspective view showing a completed product with a band thereon.

Referring to Figure 1, one wall of a. frame it is shown, the opposite wall being removed to clearly show the various operating parts of the machine which in most cases are mounted between the said walls and are supported thereby. A supply roll of banding material I! is supported in a. rack I3 between the upper portion of the machine walls and is adapted to be fed down ward in a substantially vertical direction between driven feed rollers l4-l4 and feed belts l5-I5, the latter being guided over driven rollers l5-|6 and idler rollers |1|1. Below said feed belts l5-I5 is a pair of feed belts l8, placed side idler roller 2|, said idler roller being supported by means of suitable arms 20 to allow same to pivot about the axis of the feed roller l9. Another idler roller 22 normally engages the feed belts l8 near the upper end thereof. Guide members to lead the banding material from the rolls l4l4 to rolls |6-l6 after cutting and from the belts l5-l5 to the belt l8 have been omitted for the sake of clearness.

Means is provided to cut the banding material into strips of equal length while it is being moved through the above related feeding members and comprises a stationary knife 23 supported by means of brackets 24 on the machine frame and a rotary knife 25, mounted on a'rotatable shaft the end thereof, which comprises a glue reservoir 21, supported between the walls of the frame II and having a glue roller 28 rotatably mounted within same. A transfer roller 29 is mounted upon suitable brackets 3| between the-belts l8 and is maintained in continual engagement with the glue roller so as to provide a film of glue on the periphery thereof. A driven roller 32 having a cam surface thereon is mounted on a shaft 33 between the walls of the frame II and is adapted to movethe end of the banding strip S against the periphery of the'transfer roller to thereby cause a film of glue to be deposited thereon. By means of a spring 34, which is attached to the arm 20, the strip S is drawn away from the transfer roller after the cam surface of the roller 32 moves past the strip surface.

A product 35 which as shown comprises a pack of cards, is moved to the surface of a feed table 36 either manually or by some mechanical means, not shown, and is moved along said table by means of lugs 31 spaced apart on a conveyor 38, which conveyor may be of any suitable type,

such as chains, for example, which are guided over sprockets indicated at 39-39 and one idler sprocket indicated at 4|. The sprockets and idler being mounted in any convenient manner. The drive for the product is so arranged as to move the said product into'the strip of banding material S which is positioned directly in the path of same, in a manner shown in Figures 1 and 3, and thus cause the strip S to be drawn away from the upper feed belts i5 and lower feed belt l9. Upon passing under a guide plate 42, secured to said feed table, the strip is brought into engagement with the upper, lower and forward end surfaces of the product, and a portion ,of the lower adhesive end of the strip is left trailing beyond the rearlend of the product. Also after passing under said guide plate 42, the said ed to provide a tensioned grip upon the upper and lower surfaces of the product directly over the band portion thereof and are secured to a supporting block 44. The block 44 is fixed to a shaft 45, which shaft is slidably and rotatably mounted in vertically slotted portions 46 of the frame walls and has a gear 41 at one end thereof.

A rock shaft 43 is mounted between the walls of the frame II and has arocker arm 49 positioned at each end thereof, which arms have slotted ends 5i engaging the gripper shaft 45. One of said arms shown clearly in Figure 1, which may be regarded as the operating arm, has a cam roller 52 mounted thereon, which engages the surface of an operating cam 53. Above said rocker arm 49, a reciprocable rock arm 54 is mounted on a shaft 55 positioned between the walls of the frame H, and has a gear rack- 56 at one end which engages the gear 41 on the shaft 45 and has its opposite end forked as at 51,- to slide over the shaft 55. Also mounted on said shaft 55 is a cam 58, which is adapted to reciprocate the rack arm by means of the engagement of a cam roller 59 on said arm with the cam 58. By means of a spring 61, biased between a collar 92, loosely mounted on the shaft 55 and a portion of the rack arm 54, the roller 59 is maintained in engagement with the cam 58.

Before the gripper operating mechanism functions, the same assumes the position shown in Figure 1 with the gripper normally positioned in the path of. an approaching product. After regear 41 and thereby cause the gripper to swing about the axis of the shaft 45 in the direction indicated by the arrow in Figure 2. After the gripper swings the outer end of the product and wipes same past the feed table top, the rocker arm will be lowered to return the product to the feed table in a position which will be the reverse of its original position; i. e., the said product will be turned over to move the upper surface downward and thereby bring'the saidupper surface into contact with the trailing end of the banding strip S as shown in Figure 5.

Immediately after the product reaches the table top on a second conveyor 65, pusher lugs 64 are timed to engage the end of the product to move same away from the gripper blades, whereupon the gripper mechanism is again driven through a cycle similar to that previously described but in the reverse direction, to thus return the gripper to a product receiving position. The second conveyor 65, like the first mentioned conveyor 33 may be of the chain and sprocket type and may also be mounted in any convenient manner.

From the position shown in Figure 5, the said product is, again moved along the feed table, which movement will cause the adhesive end of the strip S to be sealed to the outer surface of the opposite end of said strip around the product, when the product. is moved beneath a pressure element, indicated at 56. Said pressure element comprises a collar 61 and secured to a rotatable shaft 59, having a flexible tension member 69 thereon, which shaft is mounted between the walls of the machine frame I l.

The product is now in its completed form with the banding strip completely wrapped theresecured to a collar 13 on a rock shaftsaidshaft being mounted between the walls of the frame ll. As the lugs '4 on the conveyor 05 approach the point where they could no longer drive the product, the blade 12 will be moved forward to engage the rear end of the said prodnot and will move same clear of the feed table 36 and onto the delivery platform "ll.

The delivery platform comprises a vertically 'slidable'frame having a shelf 15 at the upper end thereof anda'nelongated slot IS- in the body thereof. A'cam roller ll, rotatably mounted on said frame, rests upon the cam surface of a cam 18, which cam is fixed on a rotatable shaft I! mounted between the frame walls. Said shaft also through the slot It. The timing of said cam 18 is so arranged as to cause the platform to be lowered a distance equivalent to the thickness of a product during each bending operation to thereby permit 'anumber-of products to he supported thereon before final delivery is made.

To further provide for the complete automatic handling of said products, an ejector member is provided which is adapted to be actuated after a predetermined number of products have been deposited upon the delivery platform. Said ejector comprises ah ejector finger 8| secured at one end of a horizontally movable ejector rod 8'2, which rod is supported in a bearing 33 suspended from a sprocket shaft 84. At the opposite end of said ejector rod, a link 85 joins same with one arm 88 of a bell crank 86 pivotally mounted on a stud 9B in the frame wall and said rod is normally retained in a retracted position by means ofa spring 8? biased between the,

arm 8% of the'bell crank and a pin on the machine frame. 'A striker lug dd projects outward from a collar 9!, which is secured on a rotatable shaft dzsupported between the frame walls, and upon each rotation of said shaft, is adapted to strike another arm 93 on said bell crank to thereby rock the bell crank and move the ejector rod 82 and finger 8| thereon forward, which movement will force the accumulated products from the delivery platform II, to a receiving table, a fragment of which is indicated by numeral 3d.

The general driving mechanism for the various moving parts described, have been omitted from the drawing for the sake of clearness but the direction of movement or rotation of said moving parts are indicated by arrows.

It will be understood that the invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and it is therefore desired that the present embodiment be considered in all respects as illustrative and not restrictive, reference being had to the claims rather than to the foregoing description to indicate the scope of the invention. 7
