[0015]

The present invention will now be described by way of examples with reference to the drawings. As shown in FIG. 1 and FIG. 2, the binding device based on this tape is basically an object to be bound (hereinafter referred to as a work).
A table 1 on which A is placed, and a large diameter ring (annular body) for winding the tape T around the work by rotating around the work on the table, this example Then, the pulley 2, the tape retainer 3 for pushing the end portion of the tape and the rotating member 4 for supporting the tape, and the crimping base provided near the tape retainer 3 for welding the tape. 5 and a movable crimping member 6 that moves forward and backward to come into contact with the crimping table, and a tape cutter 7.

The table 1 is divided into two parts to allow passage of the tape wound around the work A, and a proper gap 1a is provided between the parts as shown in FIG. .
The pulley 2 is usually supported by a guide wheel 2a located in and around the vertical plane and the table 1
Surrounding the upper work, it is rotated by a motor 9 via a transmission member 8 which is preferably a V-belt. A tape reel 10 for storing the tape T is attached to an appropriate position of the pulley, and the tape fed from the reel passes through a flexure removing lever and has a tape end at the tape end. -It is held by the presser foot 3.

The tape retainer 3 comprises a pair of rollers 3a and 3b, as shown in FIG. 7, and the tape end is held between the rollers. At least one of the rollers is adapted to be driven as described below. One of the features of this device is that the tape presser 3 and the crimping table 5 are located under the table 1 and in the vicinity thereof, and both are installed on the rotating member 4, and each time the pulley 2 is rotated by one rotation. It is to make one rotation, which prevents kinking of the tape.

The crimping member 6 which moves back and forth with respect to the crimping table 5 is constructed as a heater in this example, and is a suitable reciprocating linear driving device, preferably a rodless cylinder 1 as shown in FIG.
1, when the tapes are welded, the crimping member 6 advances toward the crimping table 5 as shown by the imaginary line in FIG. 1, and sandwiches the pair of tape parts to collide with the crimping table 5. The tape is welded together, and the tape is retracted after the welding.

As clearly shown in FIG. 7, in the first embodiment, the crimping table 5 is composed of a pair of portions 5a and 5b, and the crimping member 6 is also composed of a pair of portions 6a and 6b. The crimping table portion 5a abuts on the crimping member portion 6a, and the other portion 5b abuts on the corresponding portion 6b. The cutter 7 is preferably part 6a of the crimping member
It is installed between 6 and 6b.

The rotating member 4 is rotated by the rotating mechanism 12 (FIG. 2) once for each binding cycle. 3 and 4 show the rotating mechanism 12, and in this embodiment, an air cylinder 13 is used as a driving device for the rotating mechanism 12.
The shaft 4a of the rotating member 4 is configured to rotate via the rack 14 and the pinion 15 fixed to the shaft. In this case, a one-way clutch is attached to the pinion 15.

As shown in FIG. 7, the state in which the crimping table 5 occupies the uppermost position is the basic position or the start position of the rotating member 4, and as shown in FIGS. The brake drum 16 is fixed to the shaft 4a, and a movable brake 17 for stopping the drum 16 is installed.
This brake is operated by the air cylinder 18.

Since one roller of the tape retainer 3 is rotated, as shown in FIGS. 3 and 6, the ratchet wheel 1 is used.
9 and a ratchet 20 are used, which are advanced and retracted by an air cylinder 21 and pivoted by a pin 22 so that they are pivoted slightly upwards when crossing the top of the ratchet wheel 19. As the ratchet 20 engages with the ratchet wheel 19 and retracts, the ratchet wheel 19 rotates, and the tape pressing roller 3 rotates via an appropriate transmission member. A tape scrap and a new tape end following the tape scrap are pulled out. The rotation of the press roller 3 is for slightly pulling out the tape end, and it goes without saying that the rotation may be performed by another mechanism such as a rack and pinion.

Since the tapes are welded at two places and cut between them by the cutter 7, one welded portion is used as a binding portion for the work, and the other welded portion is used as shown in FIG.
It is sandwiched between the rollers of the presser foot 3 and pulled out, the welded portion (the lower part in the illustrated example) moves from the crimping table, and a new tape portion is pressed by the roller. Therefore, since the tape scraps are continuous, cutting the tape scraps is convenient for treating the tape scraps.

In order to cut the tape waste, (a) in FIG.
As shown in FIG. 5, the tape receiver 23 is provided at an appropriate position of the rotating member 4, in this example, a symmetrical position of the crimping table 5, and
Is a predetermined angle, and in this embodiment, when the tape is rotated halfway, the tape scraps T
1 is in that position, and the advancement of the cutter 7 cooperates with the tape receiver to cut the tape waste.

In another example, as shown in FIG. 7, in order to cut the tape scraps, the rotary member 4 is provided with another rotary cutter 24 and a roller 25 for receiving the abutment of the cutter. Then, the tape scraps may be cut by the contact between the cutter and the roller. The rotation of the cutter 24 may be interlocked with the rotation of the roller of the tape presser, for example.

FIG. 8 shows the respective operation stages of the binding device, and FIG. 8A shows the state before binding. Tee
When the work is placed on the bull 1 and the pulley 2 is rotated once, the tape T is wound around the work A as shown in FIG.
Then, as shown in FIG. 3C, the pressure member 6 is advanced by the operation of the air cylinder 11 and abuts against the pressure table 5, and the tape is welded at two points between them, and a pair of cutters 7 are used. Cut the tape between the welds.

Next, the crimping member 6 is retracted and, as shown in FIG. 8D, the roller of the tape presser 3 is moved by a predetermined amount through the ratchet wheel 19 and the ratchet 20 by the operation of the air cylinder 21. Rotate and pull out the tape end with one weld. Then, the air cylinder 13 is actuated to rotate the rotating member 4 a half turn to move the tape receiver 23 to the uppermost position, and the air cylinder 11 is actuated again to cut the cutter.
7 is advanced and the tape waste is cut as shown in FIG. Then, it makes a half rotation again to return to the initial state.

Another embodiment of the present invention is the same in that the tape retainer 3 consisting of a pair of rollers and the crimping base 5 are provided on the rotating member 4, and the rotating member 4 is rotated once for each binding. However, in this embodiment, as shown in (b) of FIG. 9 and FIG. 10, a tape portion which becomes a new tape end generated by cutting is inserted between the rollers of the tape presser 3. -Push in lever-26
And a device for driving one roller of the tape retainer 3 to rotate a pair of rollers, as in the above.

As shown in FIG. 10, the tape pushing lever 26 is preferably installed integrally with the crimping member 6 and thus with the cutter 7. As a result, the lever 26
The mechanism for activating can be made common, and is simplified. In this case, only one welding portion is required, and therefore, the configurations of the crimping base 5 and the crimping member 6 are simplified as compared with the above-described embodiment.

FIG. 9 shows each operation stage of the tape push-in lever 26 provided. FIG. 9A shows a state before binding, and FIG. 9B shows a work tape. The state immediately after winding the loop is shown. At the same time as welding and cutting of tape,
Alternatively, as shown in (c) at substantially the same time, a new tape end is inserted between the rollers of the tape presser 3 by the lever 26.

Next, when the roller of the tape retainer 3 is rotated, as shown in FIG. 9D, the tape waste T1 is removed by the cutter 7.
Is discharged in the state of being cut. Then, the rotating member 4 is rotated to return to the initial state through the steps shown in FIGS. Therefore, in this form, since the tape scraps are not connected, the cutting is not necessary, and there is an advantage that the tape scraps can be easily treated.

[0032]

As described above, according to the present invention, the tape can be wound and bound without moving the work placed on the table. −
It does not cause the load to collapse when hanging. In addition,
When the length is long, it is possible to easily bind at a plurality of points by moving the pulley perpendicularly to the surface of the pulley.

If the tape receiver is provided at an appropriate angular position with respect to the crimping base of the rotating member, it is possible to cut the tape waste with a cutter that cuts during welding or immediately after the welding. , Facilitates the processing of tape scraps.

If the tape scraps are cut by another cutter and a roller that receives the abutment of the cutter, the tape scraps can be favorably processed and the entire operation is simplified. Therefore, it becomes possible to bind at a higher speed.

Further, if a new tape end is inserted between the rollers of the tape retainer by a tape pushing lever, it is possible to prevent the work from slipping and to keep the tape at a plurality of positions. The binding is made possible and the cutting of tape waste is not required, and the mechanism is remarkably simplified.

If the tape pushing lever is configured to operate together with the cutter and the crimping member, it is not necessary to install an operating mechanism for the lever, and the mechanism becomes simpler.
