Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a binding device for binding objects to be bound which have been carried in to a binding position by a conveyor by a binding machine and carrying them out from the binding position, and in particular, binding by a cord or tape. The present invention relates to a binding device that can be selectively performed.

[0002]

2. Description of the Related Art Conventionally, as binding devices of this type, those shown in Japanese Patent Publication Nos. 51-30512 and 64-3728 are known. In the conventional bundling device, a bundling machine is arranged on one side or both sides along the work line of the work to be bound, and the work is stopped at the bundling position by the stopper to bind the work, and the work is again conveyed on the transfer line. Has become. As the binding machine, a strap or a tape is used, and therefore, it is impossible to selectively switch to a strap or a strap.

Bundling with a string has the advantage of being inexpensive, but
If the work A is water-repellent or slippery, even if the work A is bound, the load tends to collapse and the work may be damaged. Bundling by tape, that is, bundling by wrapping the tape around the work and then adhering the tapes to each other by welding, is more expensive than a string, but the width of the tape is quite large. Therefore, there is an advantage that even if the work is slippery, it can be properly bound even if the work is tightened.

Therefore, in order to selectively bind the cords and the cords in accordance with the work, in the prior art, the binding devices are provided in two stages in series, and one device is provided with the cords. A tying machine was provided and the other apparatus was provided with a tying machine to selectively use one of the tying machines. That is, as shown in FIG. 7A, when a cord is tied on both sides of a work, a binding device equipped with a cord binding device is used, and as shown in FIG. 7C, a tape binding device is used. When uniting,
A bundling device with a bundling machine was used.

In some cases, however, as shown in FIG. 7B, for example, in the case of bundling such as a stepped ball, depending on the work, only one side is bound with a tape and the other side is bound with a cord. In some cases, it may be sufficient to tie it, and if such tying is performed, the cost is reduced compared to the case of tying both sides with tape, and the tape after tying is troublesome to clean up, but the string Therefore, there is an advantage that post-treatment is easy as compared with the case where both sides are bound with tape.

[0006]

Normally, in the case of binding both sides of a work, a binding machine of the arm up-and-down movement type is used. Therefore, in the case where a binding device is provided in two stages, the work is performed in the preceding stage. It is conceivable that the cord is tied on one side of the work, or it is tied on the other side of the work in the latter stage, but in the case of one-side bundling, the posture of the work is bent when the cord or tape is fed out. So it is actually impossible to unite. Further, even if it is possible, since the bundling cycle is performed twice on each side, the bundling work requires a relatively long time, and the work efficiency is reduced.
There was a problem.

An object of the present invention is to eliminate the above-mentioned problems of the prior art. Therefore, the binding by the string and the binding by the tape can be selectively performed, and one side of the bound object can be An object of the present invention is to provide a binding device that can be suitably bound with a string and the other side with a tape.

[0014]

Embodiments of the present invention will now be described with reference to the drawings. 1 to 4 show an example of a binding device according to the present invention. As shown, the binding device 1 includes a pair of binding devices, one of which is a binding device 2 using a cord.
And the other is a tape binding device 3. The strapping arm 4 of the binding machine 2 and the tapering arm 5 of the binding machine 3 are of a type that moves up and down. In the figure, 6 is a reel for storing tape.

In addition to the arm 4, the binding machine 2 is provided with a series of binding mechanisms such as a binding mechanism and a drive motor, the construction of which is well known, and the tape binding machine 3 is also known. A
In addition to the arm 5, a crimping device by welding that interlocks with the operation of the arm is provided, and the configuration of the device itself is well known, and therefore their description is omitted. The term "welding" used herein includes heat welding as well as welding using high frequency waves or ultrasonic waves.

The binding device includes a movable support base 7 for supporting those binding devices, and preferably a drive device 8 for rotating the support base at a predetermined angle. Therefore, each binding machine 2, 3
Is fixed at a predetermined position on the support base 7. The binding device 1 is provided with a work loading / unloading conveyor, preferably a belt conveyor 9. Further, as shown in FIGS. 2 to 4, a carry-in roller conveyor 10 is provided at the entrance side of the conveyor 9.
Further, the carry-out roller conveyor 11 is connected to the exit side. A press device 12 for pressing the work is provided above the conveyor 9, and a stopper 13 for stopping the carried work at the binding position is provided at an appropriate position along the conveyor 9. If desired, a horizontal aligning plate for the work and a stopper for holding the rear end of the work are provided.

As shown in FIG. 5, the support base 7 is movably supported on the base 15 by an appropriate number of wheels 14 provided on the lower side thereof, and in this embodiment, it is provided at a substantially central position. The shaft 16 is rotatable about the shaft 16. Reference numeral 17 is a thrust bearing. The support base 7 may be rotatably installed by another support structure. Preferably, the base 15 is adjustably supported on a rail 19 by means of a wheel 18 provided on its underside, as shown in FIG.

In this embodiment, a hydraulic cylinder is used as the drive unit 8, and the support base 7 is rotated via a rack 20 fixed to its piston rod and a pinion 21 fixed to the shaft 16 and engaged with the rack 20. However, an electric motor may be used as the drive unit 8 and the support base may be moved via an appropriate transmission device. Further, in the illustrated example, the pair of binding machines 2 and 3 are arranged so as to face each other on the support base 7,
That is, it is at an angular position of 180 degrees with respect to the central axis 16, so that the support base 7 can be rotated 180 degrees by a suitable sensing device such as a limit switch.
2, the binding machine 2 at the binding work position is displaced from that position, and the other binding machine 3 is placed at that position, as shown in FIG. Is installed at the bundling work position.

Both sides of the work are bound, for example, in the case of bundling the step balls. In such a case, as shown in FIGS. 1 and 2, the binding device 1 serves as a binding machine assembly and the two are opposed to each other. Will be placed. This binding device 1 is preferably used because it is arranged in such a manner.
The lacoveer 10 and the carry-out roller conveyor 11 are commonly used, and the guide roller 22 provided above the belt conveyor 9 on the work carry-in side is also commonly used.

When a binding operation is performed by arranging a pair of binding devices 1 facing each other and placing each binding machine 2 at a binding operation position as shown in FIGS. The work carried in by the conveyor 9 hits the string stretched from the tip of the arm 4 of each binding machine 2 and is stopped at the binding position by the stopper 13 while pulling out the string and pressing by the press device 12 and The hooks are hooked by lowering each arm 4, and the knot is formed and the cords are cut by the binding mechanism.

Further, the drive device 8 of each binding device is operated to rotate the support base 7, the binding device 2 is replaced with the binding device 3 by tape, and the binding device 3 is bound as shown in FIG. If the work is installed at the work position and the bundling work is performed, bundling is performed by the tape T on both sides of the work as shown in FIG. 7C in the same cycle as described above.

Further, as shown in FIG. 2, only one of the binding machines 2 is replaced with the binding machine 3 by tape while the binding machine 2 by the string of each binding device 1 is in the binding work position. By this, when being carried into the bundling position, it is stopped by the stopper 13 while simultaneously pulling out the cord on one side and the tape on the other side, so that one side of the work is a cord and the work is The other side is bound together by a tape, and the work is bound by a string S on one side and a tape T on the other side as shown in FIG.

The binding device 1 can be used alone, and in that case, both binding with a cord and binding with a tape can be performed. Further, there is an advantage that the binding machine can be easily replaced by rotating the binding device, but this replacement can be performed by another moving method, and in some cases, can be manually performed. .

[0024]

As described above, according to the present invention, the binding of a string or tape can be used for binding the objects to be bound, and the string or the tape can be bound depending on the type of the object to be bound or other conditions. You can choose the bundling according to the type.

If the binding machine can be replaced by rotating the support base by the drive device, the binding machine can be replaced by the push button method or the automatic control method, and the replacement can be performed very easily.

By arranging two tying devices each having a tying machine and a tying machine, the two tying devices can be tied together by ties or tapes when tying both sides. At the same time, it is possible to suitably bind one of the objects to be bound with a string and the other side with a tape. Therefore, bind the both sides of something that is easy to slip such as a step ball,
It is possible to use one side with a string and the other side with a tape, which can reduce the cost required for binding and facilitate the processing after releasing the binding.
