FLOYD A. LYON BANDING MEANS This invention relates to banding means, and more particularly, to means for wrapping and sealing a tape around a package.

The invention particularly relates to means for feeding a band around an article at the same time the article is being inserted in the banding station.

In conventional banding machines, the article or package is first inserted in the banding station andthen the machine is energizedto draw the band around the article or package.

In the present invention, the band is formed by four retractable fingers which are mounted on a rotary ring which encircles the bandin g station so that the band may be wrapped around the fingers while the package is being inserted. There is no snubbing action as the tape is fed. Since there is no strain on the tape, it may be fed faster without danger of snapping. As soon as the band is completely wrapped around, the fingers are retracted and the slack is taken up and the band snugly wrapped around the package, regardless of the size of the package, and the tape is then sealed.

Since a package may be inserted while the tape is being fed, the normal timing cycle is cut to approximately one half during production runs.

Accordingly, a principal object of the invention is to provide new and improved banding means.

Another object of the invention is to provide new and improved high speed banding means.

Another object of the invention is to provide new and improved high speed banding means for packages of variable sizes.

Another object of the invention is to provide new and improved high speed banding machines having four retractable v fingers mounted on an encircling means which rotates around the package so that the tape is drawn around with no snubbing strain when the fingers are retracted and the slack taken up, the band is wrapped around the package.

Another object of the invention is to provide new and improved banding means wherein the package may be inserted while the tape is being fed around the banding station so that the normal time cycle is cut substantially in half.

. Another object of the invention is to provide a new and improved banding machine of the type feeding a band around at least one article in a banding station, means adapted to encircle said banding station, a plurality of fingers movably mounted on saidencircling means, said fingers being spaced so that a band formed by said fingers will encircle said article, means to feed said band so that said fingers form said band around said station, means to retract said fingers after said band is formed completely around and over said fingers and encircles said banding station, and means to pull said band snugly around said article in said banding station, whereby an article may be inserted into said banding station at the same time said band is being formed around said fingers.

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

FIGS. lA-ll-I are diagrams illustrating the operation.

FIG. 2 is a front view of the ring and finger mechanisms.

FIG. 2A is a developed side view of an embodiment of the invention.

FIG. 3 is a front view of FIG. 2A.

FIG. 4 is a timing diagram showing the developed cam shapes.

Referring to the drawings, FIGS. 1A-1G illustrate the method of operation. FIG. 1A represents the starting position. The package P is placed on a fixed locating platform and extends through the ring 1 which is rotatably mounted. A tape clamp 13 is mounted on the ring 1 and the tape T is fed from the reel 3 around the guide roller 4, which is mounted on a long pivotally mounted arm 5. Four retractable fingers 6, 7, 8, 9 are mounted on the ring 1. The fingers are mounted so that as the ring rotates around the package, the tape is formed around the fingers. The fingers are rotatably mounted so that they can be retracted out of the tape path so that the tape can be tightened up around the package.

FIG. 1C shows the operation after the ring has rotated one turn. The tape T is wrapped around the fingers 6, 7, 8, 9.

FIG. 15 shows the next step with the fingers retracted and the arm 5 swung to the right to take up the slack in the tape T to cause the tape to be snugly wrapped around the package P.

Referring to FIG. 1E, the tape is sealed around the package by a heater 12. The free end of the tape is then gripped by the pawl Me on the feeder arm 14 and the tape is severed by the knife 11.

Thereafter, FIG. 16, the feeder arm feeds the free end of the tape T into the clamp 13 which returns the apparatus to the starting position of FIG. 1A.

Since a package may be inserted during the operation of wrapping the tape with the fingers, the average forming cycle is reduced by approximately one half; In other words, it is not necessary to insert the package before starting .the cycle, so that the forming of the tape around the fingers, which is a substantial part of the cycle, and the inserting of the package may be done at the same time.

FIGS. 2 and 2A show front and side views of the mechanism for operating the fingers. The fingers 6, 7, 8, 9 are pivotally mounted on the ring 1 and are normally held in extended position against stops 8', 9, etc. by means of springs 15, one on each side. The upper pair of fingers are connected by a bar 17 and the lower pair of fingers by a bar 18. The fingers are adapted to be rotated to retracted position by means of the linkage comprising pivotally mounted members 17', 18' which are positioned to contact the bars 17 and 18 to rotate the fingers. On the other ends of the members 17 and 18 are connected linkage members 17a, 18a which are adapted to move vertically. The lower end of linkage members 17a and 18a are pivotally connected to crank arms 17b and 18b. The other ends of the crank arms 17b and 18b mount cam followers 17c and 18c which ride on cams 17d, 18d mounted on cam shaft 21, so that all the fingers are retracted simultaneously.

Referring also to FIG. 3, the tape T is wrapped around the box or package P by means of the traveling clamp 13 which is mounted on a ring 1 which is rotatably mounted on the frame. The ring 1 is driven by shaft 26, slip clutch 47, shaft 29, and gear train 29' 28, 28 which meshes with external gear 1' on ring 1. Camshaft 21 and ring 1 have a 2:1 ratio as the ring is rotated during only the first half of the camshaft 21 rotation. Ring 1 rotates on rollers 1a, 1b, 1c, 1d. Shaft 26 is motor driven by motor 43. A positioning stop 30 for the clamp drive is mounted on the disc 31 which is fixedly connected to the shaft 29. The stop 30 is adapted to be released by the stop arm 16 operated by cam 16' and is held open by cam 16' for one ring cycle. Arm 16 is spring connected to arm by spring 16'. Arm 16a is cam operated by means of the linkage comprising pivotally mounted arm 16a joumalled to the table, connecting link 16b and rocker arm 160 which is mounted on the rocker arm shaft 20 and the other end of which rides on the cam 16' mounted on the common camshaft.

The stop 30 is set to stop the clamp 13 in a position underneath the package P where it will receive the end of the tape from the tape feeder arm 14. The tape T is fed from the reel 3 around the roller 4 on arm 5 and thence to the tape feeding arm 14.

The heater and knife mechanisms and means for feeding the tape end to the clamp, and the clamp itself, may be as shown in US. Pat. No. 2,971,307. Cam shaft 21 is driven from shaft 26 by gear 21 and idler gear 21".

The arm 14 is adapted to be actuated by the cam 14' by means of the linkage comprising rocker arm 14a which rides on the cam 14, connecting member 14b which is pivotally mounted on rod 14d and fixedly connected at its other end to the arm 14. The rod 14d is journalled to the frame.

The cam operated heating iron 40 is mounted to heat seal the plastic tape after it has been wrapped around the package or box P. The heating iron 40 is mounted on an arm 12 which is pivotally mounted to the main frame at the point 12a. It is connected to be actuated by the cam 12' by means of the linkage comprising the rocker arm 12b and a connecting link 12c which is pivotally connected at its ends to the rocker arm 12b and the arm 12. The heater 40 element may be the cartridge type of the kind employed in soldering irons. The 150 watt size has been found satisfactory.

A knife is connected to sever the tape T after the heat sealing. It comprises a rotatable knife blade 11 which is pivotally mounted on the block 11a on the frame and which is connected to be actuated by the cam 11 by means of the linkage comprising the rocker arm 11b which rides on the cam and which is connected to the blade 1 1 by means of the connecting rod 1 1c.

The clamp 13 is normally spring closed by a spring 13c, but is adapted to be opened by means of the arm 13c moving arm 70 connected to clamp jaw 57. Ann 130 is operated by the cam 13' and connecting linkage comprising a rocker arm 13a and connecting member 13b connecting the rocker arm to the frame mounted shaft 13d and which is fixedly connected at its other end to the arm 131:.

Power to ring 1 is provided by motor 43 via shaft 26 and slip clutch 47, the output of which is connected to shaft 29. When the stop 30 is engaged by arm 16, the clutch 47 slips. Shaft 29 is geared to ring 1 by gears 29 28, 28. The clamp 13 is fixed to the ring 1 and is shown in FIG. 3 in position to receive the end of the tape from the tape feeder 14 which is pivotally mounted on shaft 14d journalled to the frame.

The tape feeder 14 has a long extension 50 at right angles to the top of the arm in which the tape is held by a spring. The extension 50 fits through a slot 51 in the block 110 attached to the frame and to which the knife 11 is pivotally mounted. The tape feeder arm 14 is retracted to the position shown by the dotted lines when the knife 1 1 is operated. The arm 14 motion is at least the distance from knife 11 to clamp 13 in loading position.

The tape T is clamped in the arm. 14 by means of the wedging action of the pawl Me which is pivotally mounted on the arm. The upper end 14f of the pawl squeezes the tape against the surface 14g. The pivot point 141: is displaced from the contact point so that when the arm 14 ismoved up, the pawl 14e grips the tape with a wedging action. However, when the arm 14 is rotated down, the pawl 14e does not grip the tape so that the tape can slip. The adjustable stop 52 opens the pawl 14e in a positive manner when the arm 14 is in the position shown in the dotted lines. The stop 52 comprises a screw,

52a in a threaded stud 52b mounted on the frame. This permits the tape to ride freely during the travel time of the clamp. Also, since the ring travel is greater than the length of tape required to band the box, some tapemust be retracted each cycle. This is done by the arm pulling the tape back through the opened pawl 14c.

The arm 5 (FIG. 3) is pivotally mounted and is operated by cam 5 and linkage comprising rocker arm 50, which is pivotally connected to one end of elongated member 5b, the other end of which is slidably connected to arm 5 by slide 5c. The reel 3 has a brake 30 set so it is not moved by movement of arm 5. The arm 5 travel is sufficient to take up all slack for the smallest package P desired to be wrapped. Alternatively, the arm 5 could be spring loaded to the right in FIG. 3, and the cam 5' linkage omitted.

The ring 1 is driven in predetermined synchronism with the camshaft 21. it is started by cam 16 releasing arm 16 and it is stopped by cam 16' which is connected to operate stop 30. Ring 1 is driven from shaft 29 by gears 27, 28, 28 which meshes with gear 1 on ring 1. The ring rotates twice as fast as the camshaft and only rotates from 0l 80 of the camshaft.

All cams are mounted on the common camshaft 21 which is mounted in the bearing blocks 21a and 21b connected to the frame. All the associated rocker arms are mounted on the common rocker arm shaft 20 which is mounted in the bearing blocks 21a and 21b, connected to the frame.

The knife 11 is pivotally mounted on the block 11a connected to the frame which has a slot 51 therein through which the tape feeder extension member 50 is inserted to feed the end of the tape to the clamp 13. The knife 11 is pivotally connected to the connecting rod 11c which is pivotally connected at its other end to the rocker arm 11b mounted on the shaft 20. The other end of the rocker arm 11b has a cam follower spring loaded against the cam 11'. The blade 11 shears the tape with a scissor action against a stationary cutting edge 59, FIG. 3. I

The heater iron 40 is mounted on the arm 12 which is pivotally mounted on the shaft 12a joumalled to the frame. The arm 12 is operably connected to the connecting rod 12c which is connected at its other end to the rocker arm 12b mounted on the rocker arm shaft 20. The other end of the rocker arm 12b has a cam follower which is spring loaded against the cam 12'.

Clamp 13 comprises a plate member 60 having a recess 56 for receiving the end of the tape. The tape is then clamped in the recess by the arm 57 which is pivotally mounted on the plate 60. An angled extension 70 of the arm 57 is spring loaded in closed position by the spring 13. The clamp is adapted to be opened by means of the arm 13c and is connected at its other end by means of the connecting rod 13b to the rocker arm 13a mounted on the rocker arm shaft 20. The other end of the rocker arm 13a has a cam follower which is spring loaded against the cam 13.

The tape feeder arm 14 is pivotally mounted on the shaft 14d joumalled to the frame. Extension arm 14b is fixedly connected to the arm 14 and pivotally connected at its other end to the rocker arm 14a mounted on the rocker arm shaft 20. The other end of the rocker arm 13a has a cam follower which is spring loaded against the cam 14'.

The stop arm 16 initiates the ring cycle by cam release of stop 30 on the disc 31 mounted on the power shaft 29. The stop control arm 16 is pivotally mounted on the shaft 16d which is joumalled to the frame. The arm 16 is spring connected to arm which is connected by means of connecting rod 16b to the rocker arm 16c mounted on the rocker arm shaft 20. The other end of the rocker arm 160 has a cam follower which is spring loaded against the cam 16. The ring cycle is stopped by action of cam 16 moving arm 16 to stop position.

The plate 60 preferably contains a rubber insert, for instance, of soft, heat resistant rubber, against which the heater iron seals the tape together. The 'use of the rubber insert prevents loss of heat since it is an insulator and also due to the fact that it is elastic so that maximum contact is obtained between the heater iron and the tape.

All of the mechanisms above described are synchronized and controlled in a predetermined sequence'by means of the cams mounted on the motor driven camshaft. The sequence of operation is plotted by the cam development diagrams of FIG. 5. Each diagram is the developed periphery of the respective cam.

Referring to FIG. 4, to start the cycle, momentary pushbutton switch 60 starts motor 43 which rotates cam 600 off the indent and engages bypass switch 60 which holds the motor 43 on from 0-l80 and then stops it. The tape is formed around the fingers during 0-l 80. At a package is inserted and switch 60 pushed again for the wrapping operation. More specifically, the stop 30 is released by the cam 16 and the tape is pulled by the fingers of the ring 1. After one ring revolution the ring is stopped 180) by stop 30 hitting arm 16, the stop arm having been moved into position by cam 16'.

The fingers are then released by cams 17d, 18d and associated linkage (180) and the long tape feed arm 5 is retracted by cam 5' and its linkage 180) to take up the slack and wrap the tape snugly around the package. The slight slack caused by the clamp is taken up by the elasticity of the tape after the package and wrapped tape are slid off the clamp and ejected.

The heating iron 40 is then actuated by the cam 13' to heat seal the tape loop (220-250) and the knife 11 is actuated by the cam 11' to cut the tape (230). The clamp 13 is then released by the cam 13' and connected linkage. The package is now ready to be ejected. The tape feed cam 14 has moved arm 14 (190) so that the tape is gripped by pawl l4e before the tape end is severed. The tape feeder arm is then rotated by the cam 14' and associated linkage to place the end of the tape into the clamp 13. The clamp grips the tape (320) as the clamp arm 13c is released. The tape feeder arm 14 is retracted out of the way of the knife during the cutting. The apparatus is now ready for a new cycle. a

The encircling means is shown as a ring, but may be a chain on a track or other equivalent means.
