A principal object of the invention is to provide new and improved article banding means.

Another object of the invention is to provide new and improved article tape banding means having a rotatable arm adapted to rotate around the article or articles to be banded and means to feed tape through said arm and around said articles.

Another object of the invention is to provide new and improved article banding means having a rotatable arm adapted to rotate around the articles to be banded and means to feed tape through said arm around said articles, means to seal said tape around said articles and means to out said tape.

Another object of the invention is to provide new and improved banding means for plastic tape having automatic heat sealing and cutting means.

Another object of the invention is to provide new and improved means for handing articles comprising a frame,

a platform for said articles said platform having a slot, an arm rotatably mounted on said frame to rotate parallel to said slot, means to feed tape along said arm and through said slot, a clamp connected to the under side of said platform to receive the free end of said tape, heat sealing means adapted to seal said tape when wrapped around said articles by said arm, knife means adapted to cut said tape when sealed, and tape feeding means connected to grip said tape before cutting and to feed the free end of said tape to said clamp.

Another object of the invention is to provide new and improved banding means for pressure sensitive tape.

These and other objects of the invention will be apparent in the following specification and drawings of which:

FIGURE 1 is a broken perspective view of an embodiment of the invention.

FIGURES 2 through 7 are schematic views illustrating the sequence of operation.

FIGURE 8 is a time sequence diagram.

FIGURE 9 is a perspective View of a modification of the invention, and

FIGURES 10-16 are schematic views of the operation of the modification of FIGURE 9.

Generally referring to FIGURE 1, there is shown a table 1 which acts as the main frame for the apparatus. The package P is placed on the table so that it is supported by the table 1 at one end and by the rotatable platform 2 at the other end. The arm 3 which feeds tape T is adapted to swing around in counterclockwise direction passing the tape around the package through the slot formed between the end of the table and the platform 2.

A heat sealing iron 4 is pivotally mounted on the underside of the table for the purpose of sealing the tape. A knife 5 is also pivotally mounted on the underside of the table for the purpose of cutting the tape after it is sealed. A clamp 6 is similarly pivotally mounted on the underside of the table and adapted to clamp the free end of the tape against a plate 6' on the underside of the table. A clam-shell type clamp 19, 11 is mova-bly mounted on carriage 12 for the purpose of gripping the tape be- "ice fore it is cut and then feeding the free end of the tape into the clamp 6. All of these elements are cam driven by a series of cams on the frame mounted cam shaft 14 which operates a series of crank arms mounted on the frame mounted crank shaft 15.

More specifically referring to FIGURE 1, the tape T is mounted on a spool or reel R which is rotatably mounted on a bracket 20 which is fixedly connected to the shaft 21 which is journaled to the frame member F. The rotatable tape arm 3 is fixedly connected to shaft 21 near the other end thereof. The shaft 21 is driven by means of the chain 23 which is connected to the sprocket 24, fixedly connected to shaft 21, and the sprocket 25 is fixedly connected to cam shaft 14.

The shaft 21 is hollow and the tape T is fed from the spool to the hollow shaft through the guide aperture 30 along arm 3, around the guide roller 31, along arm extension 3 and around guide roller 22 which is in the plane of the slot '5 between the end of the table 1 and the platform 2, which is suspendably mounted on the end of shaft 21, with suitable bearings so that it remains stationary.

The platform 2 is preferably made of a yielding light spring material so that the package may be ejected against it. In other words, the platform member 2 is adapted to yield so that the package may be pushed against its sufiiciently so that the sealed band will ride from under the stationary plate 6' against which the heating iron strikes. The platform may be eliminated and the article held solely by the table, if desired.

The arm 3 is steadied and guided by means of the

idler gears

26, 27 mounted on the shaft 28 which is connected to the arm 3. The idler gears 26, 27 mesh with the

idler gears

26, 27' which are mounted for free rotation on the shaft 21. Gear 27' is preferably pinned to frame F by pin G.

Assuming for the moment that the free end of the tape is clamped underneath the package P then as the

arm

3, 3 rotates counterclockwise, the tape will be drawn around the package P or bundle as indicated by the dotted lines P. Note that as the shaft 21 rotates, the spool or reel R rotates with it.

Clamp 6 is pivotally mounted on shaft 9 which is connected to the underside of the table 1 so that the clamp can grip the end of the tape against the plate 6, mounted on the underside of the table 1. The clamp 6 is operated .by the cam 6a mounted on cam shaft 14 by means of the cam arm 6b mounted on the crank shaft 15 and connected to the clamp by means of the link member 60.

The heater 4 is also pivotally mounted on shaft 9 on the underside of the table 1 and is operated by means of the cam 4a, crank arm 4b, and link member 4c.

The knife 5 is pivotally mounted on a shaft 9 underneath the table 1 and is operated by means of the cam 5a, crank arm 5b, and connecting link 50. Knife 5 is adapted to shear the tape against the clamp 6. All of the cam follower arms are suitably spring loaded in conventional manner. A hot wire device may be used as the knife.

The clam-shell tape feeding clamp comprises the members 10 and 11 which are adapted to open to 180. These members are mounted on the carriage 12 which is slidably mounted on

table rods

12, 12". The carriage 12 is moved in and out by means of the cam 12a, crank arm 12b, the end of which is connected by means of a pin and slot connection to the carriage 12.

The tape feeding clamp members 10 and 11 are rotatably mounted on bracket 12d mounted on the carriage 12. and they are adapted to be rotated from a full-open position of into contact with each other in order to grip the tape T, by means of the

gears

40 and 41 which mesh together. The gear 41 also meshes with and rides along the long gear 42. The clamp 10, 11 is operated by means of the cam Illa, crank arm 1%, and connecting links Title, lltld which is fixedly connected to the gear 42. The gear 42 has a considerable length to permit sliding contact with the gear 41.

The cam shaft 14 is driven by the continuously rotating motor M by means of the belt 43 which drives the pulley 44 which is freely rotatable on the shaft 14. The ulley 44 is connected by means of clutch 45 to the indexing disc 46 which is fixedly connected to the shaft 14. The indexing disc 46 has an indexing projection 46:: which is pivotally mounted on the table 1. The stop 47 is connected by means of the member 47a to a foot pedal 4-8 which is adapted to initiate each cycle.

In operation, the package P or bundle is first placed in position manually, or by other apparatus outside the scope of this invention, and the foot pedal 48 is then pressed to release the apparatus for one cycle. All of the other cams are adjustably fixedly mounted on the shaft 14 so that when the foot pedal 48 is pressed, the lock 47 will release the disc 4a to initiate the cycle. When the foot is removed from the pedal, the spring 47b will return the locking lever 47 so as to stop the apparatus in the index position. If desired, the reel R may be mounted directly on roller 29 at the end of arm 3.

FIGURES 2 through 7 show schematic representations of the sequence of operations, and FIGURE 8 shows a time sequence diagram represented by the developed cam shapes.

In FIGURE 2, apparatus is in the index position, and the feed clamp 10, 11 has gripped the tape and the tape has just been cut by the knife. Thereafter the feed clamp 14), 11 moves the free end of the tape according to the graph B of FIGURE 7 to the in position where it is gripped by the clamp 6 according to the diagram C, FIGURE 8.

FIGURE 3 shows the feed clamp 10, 11 in the in position and the free end of the tape gripped by the clamp 6, against plate 6'.

Note that when the feed clamp is moving into the in position it is moving against the arm travel. However, the spool is free to turn and does not place any appreciable load on the feed clamp movement in. The arm 3 then travels around until it reaches the index position where it is stopped by means of the

lock

46, 47.

FIGURE 4 shows the arm 3 rotating counterclockwise. Note that the feed clamp 10, 11 has been fully opened to 180 separation to permit the movement of the tape T.

FIGURES 5 and 6 show continued movement of the arm 3 in a counterclockwise direction.

FIGURE 7 shows the arm 3 approaching the index position. At this time the feed clamp 10, 11 grips the tape, the heater 4 seals the tape around the package and the knife 5 cuts the tape, as shown in time sequence diagram FIGURE 8. The heater 4, knife 5 and clamp 6 are then moved down into the index position of FIG- URE 2. The package P is then ejected by pushing it against the yielding holding member 2 until the sealed tape slips out from under the plate 6 against which the heating and cutting took place. The plate 6 is relatively thin. The tape T has been wrapped fairly tightly so that there will not be any appreciable slack in the sealed tape.

FIGURE 9 illustrates a modification of the invention for use with pressure sensitive tape T. In this modification the heating means is eliminated and the knifeclamp means are adapted 0 open 180". Also the free end of the tape T is stuck directly on to the article by means of the clamp 50 which is pivotally mounted on the shaft 51 and which is operated by means of the linkage comprising the membcr 50a, cam follower arm 50b, and cam 500.

The knife 52 is pivotally mounted on the shaft 51' which is operated by the linkage comprising the member 51a, cam follower arm 51!), and cam 51. The tape feeding clamp 1 11 is mounted on the sliding bracket 12a which is slid back and forth on the

bars

12 and 12 in the same manner which is previously described in connection with FIGURE 1. The clamp 10 and 11 is operated by the gear 42 and the linkage comprising the member Itld, 19c, crank arm 10b and cam lite.

The bracket 12a is operated by means of the crank arm 12:! and cam 12:; in the same manner as previously described. The respective cams are cut to follow the sequence shown in FIGURES 10 through 16.

Holding means for the package P may be provided comprising a pair of

curved spring members

54 and 55 which are adjustably mounted on the holder 2, for instance by spaced mounting holes on through 63. If desired, the holding means may be mounted on the table 1 and the platform 2 eliminated.

FIGURES 10 through 16 show the sequence of operations of the embodiment of FIGURE 9. In FIGURE 10 the arm 3 is in index position and the clamp 10, 11 is about to move the tape T to the left under the package P as illustrated in FIGURE 11.

In FIGURE 12 the clamp or pressure applicator 50 comes up and clamps the end of the tape to the bottom edge of the package P. The clamp 5t} then retracts as shown in FIGURE 13. Note that the knife 52 and clamp 56 open so as not to interfere with the passage of the tape T. Also in FIGURE 13 the clamps 10, 11 have been moved sufiiciently far to the right so as not to interfere with the passage of the tape.

FIGURE 14 shows the tape arm rotated almost fully counterclockwise to the index position. The clamp 10, 11 has moved to the left sufficiently to engage the tape as the clamp 10, 11 closes.

FIGURE 15 shows the clamp 10, 11 in closed position.

FIGURE 16 shows the knife 52 closing to sever the tape against the clamp 59, which has been raised, with a scissor type action, which completes the cycle.

The package is preferably placed slightly to the left of the knife so that a short projecting portion of the tape may be used as a grip for easily opening the package.

Various modifications will occur to those desiring to use the invention for instance, instead of a box or article, a bundle of envelopes or small articles may be banded together. For such use it may be desirable to add a compressing foot or feet for the purpose of compactIng the bundle.
