It is designed to be cut at

Therefore, when binding soft objects such as vegetables, there is a problem in that excessive force is applied to the objects due to the tightening of the tape and the pressing force of the curved plate 44, causing damage to the objects.

In addition, in the apparatus shown in FIG.
Since the tape T is tightened by the unwinding device 48 of the tape reel 40 during binding, the object A placed on the tape 3 tends to be pulled toward the tape crimping table 46.

Therefore, when bundling soft objects such as vegetables, the objects are pressed between the mounting table 43 and the crimping table 46, and the shape of the bundle of objects is also deformed. Vegetables may rub against each other, or the mounting table 43
There was a problem in that it hit the objects and damaged the objects to be tied.

In order to solve these problems, the present invention provides a protective layer and a tightening body to protect the objects to be bound on the mounting table, so that the binding tape can be used to prevent the objects from being bound by the back tension of the unwinding device. To bind objects to be bound, such as vegetables, without damaging them by relieving the force of pulling vegetables toward the front side of a mounting table or pressing them against the front part of a mounting table.

(Means for Solving the Problems) In order to achieve the above object, the present invention includes a binding arm that is pivotally mounted on a base and is movable up and down, and provides rewinding to the tape reel when the binding arm is tilted.

(Function) With this configuration, when the binding arm is tilted and the tape is bound on the tape crimping table, the binding tape is removed by the unwinding device so that the binding of the objects to be bound does not loosen. This allows for reliable binding by applying back tension to the tape, but the back tension applied to the tape by this unwinding device may cause the objects to be bound to move toward the front of the mounting table or to the front of the mounting table. A pressing force acts.

For this reason, a protective layer such as an elastic member is provided on the mounting table, and a clamping body is pivotally mounted, and the coil spring of the clamping body and the protective layer are adapted to fit the circumferential shape of the object to be bound. As a result, the above-mentioned pressing force is alleviated, so that there is no possibility of locally damaging the objects to be bound and the inside of the objects at the portions that come into contact with the mounting table.

In this case, the coil spring 35 and the protective layer 3B on the upper part of the mounting section 3 fit the circumferential shape of the object A and elastically press the circumferential surface with a substantially uniform force. The shape of the bundle can be adjusted easily, and the bundle can be tightened evenly with a gentle force. Therefore, the objects A to be bound will not be locally damaged.

In this tightened state, the toe portion 33A of the stopper member 33 engages with the ratchet wheel 31, so that the coil spring 35 maintains the object A to be tied in a tightened state.

In this case, the stopper member 33
Since the support 27 is fixed by engaging with the toe portion 33A of the support 27, the support 27 can be fixed at any rotational position. Therefore, it becomes possible to appropriately tighten objects of various sizes.

Next, the binding arm 4 is lowered to wrap the tape 6 around the object A. At this time, the excess tape that has become slack due to the lowering of the binding arm 4 is rewound onto the reel 5A by the tape feeding device 5. In this case, since the tape 6 wound around the object A on the placement section 3 is located in the recess 3A of the placement section 3, there is a gap between the placement section 3 and the object A. The reel 5A is not restrained and is smoothly rewound to the reel 5A side. Thereafter, as the binding arm 4 descends, the tape pressing body 15 collides with the tape pressure bonding table 2 via the tape 6, and the adhesive surfaces of the tape 6 wound around the object to be bound A are bonded together. At this time or after that, the inclined cam portion 17A
, and then when the binding arm 4 descends, the spring 1

Thereafter, as the binding arm 4 descends, the third tape holding member 20 descends while being engaged with the tape holding groove 9A, and the fifth As shown in the figure, it enters between the second tape holder 13 and the first tape holder 9.

In addition, when the second tape holding body 13 moves backward, the arm portion 3 of the stopper member 33 is moved as shown in FIG.
3B and press the toe portion 33A of the stopper member 33.
In order to release the object A from the ratchet wheel 31, the clamping body 27 is rotated back to the rear by the force of the spring 32, and the object A is released from its restraint.

As shown in FIG. 5, when the auxiliary tape holder 25 collides with the first tape holder 9 via the tape 6, the third tape holder 20 also stops descending, and the first
The rotation of the tape holding body 9 also stops. Further, at the same time as or before the auxiliary tape holder 25 collides with the first tape holder 9 via the tape 6, the second tape holder 13 reaches the vertical cam portion 17B, and then the binding arm 4 descends. Then, the spring 23 is shortened, and the auxiliary clamping body 25 is kept in contact with the first tape clamping body 9, and the second tape clamping body 13 is maintained at a constant distance from the first tape clamping body 9. dripping

Then, as the binding arm 4 descends, the cutting blade 18 cuts the first tape holder 9 and the second tape holder 13.
The tape 6 is cut. Further, the tape escape rod 19 enters between the second tape holding body 13 and the tape crimping table 2 together with the cutting blade 18, and the tape 6
The end of the crimping part side is pushed out between the second tape holding body 13 and the tape crimping table 2. Therefore, the end portion of the tape 6 on the crimp portion side is not held again between the first tape holder 9 and the second tape holder 13.

After that, when the binding arm 4 is raised, the cutting blade 18
The tape relief rod 19 returns upward, and the spring 23,
16 returns to the extended state.

After the spring 23 returns to its original stretched state and the auxiliary clamp holder 25 separates from the first tape clamp 9, reverse rotation of the first tape clamp 9 is restricted, so that the third tape clamp Tip shaft portion 20A of body 20
1 rises along the outer periphery of the first tape holder 9 while pressing the tape 6 onto the first tape holder 9, and returns to the state shown in FIG.

By repeating the above operations, it is possible to repeatedly bind objects to be bound.

(Effects of the invention) As is clear from the above explanation, the present invention provides a protective layer and a clamping body on the upper part of the object placement part, and the protective layer and the coil spring of the clamping body are connected to each other. Since the tape fits around the circumferential shape of the bound object and elastically presses the circumferential surface with a uniform force, it can be used to bind objects that have internal gaps, such as flower bouquets and vegetable bundles, with tape. It becomes possible to perform reliable tape binding without locally damaging the objects to be bound.
