Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a binding device for binding objects to be bound using a heat-sealable tape as a binding tape.

BACKGROUND ART Conventionally, as shown in FIG. 4, this type of binding device has a heating member 31 installed at a predetermined distance from a tape holder 30 that holds the cut end of a binding tape T, and a tape. The binding tape T moves up and down with respect to the holding body 30 and cooperates with the heating member 31.
A fusing member 32 that heats and fusing the polymerized winding ends of
a head portion 33 provided so as to face the heating member 31;
There is also a cutting blade 34 that enters between the heating member 31 and the tape holder 30 and cuts the vicinity of the winding end of the city binding tape.
(See Publication No. 30243).

In this device, the arm 3, which is pivoted and rotated by the base 1, continues to descend even after the pressure contact rod 35 comes into contact with the workbench 36, and the arm 3 compresses the spring while the push-down piece 37 pushes the tape T. The tape T is pushed down to fit between the locking protrusion 38 and the rubber roller 39 and a new portion of the tape T is brought into contact with the rubber roller 39.

At the same time, the heating member 31 is energized and the tape T is fused to the fusion member 32 by pressing. Further, following the operation of the push-down piece 37, the cutting blade 34 enters the cutter groove (not shown) and the tape T
cut.

After cutting the tape, when the arm 3 rises, the cutting blade 34 and the push-down piece 37 are separated from the upper surface of the workbench 36, the objects S to be bound are bound by the tape T, and the holding of the objects to be bound is released. do.

At this time, the tape T is held between the locking protrusion 38 and the rubber roller 39, and is stretched between the head portion 33 and the tape holder 30 while being stretched for the next operation.

Problems to be Solved by the Invention However, in the above device, the push-down piece is pushed between the rubber roller and the locking protrusion to clamp a new tape before cutting the binding tape. The initially clamped tape is overlapped and clamped with the newly clamped tape despite the pushing-down piece being pulled up. Since the tape is then cut, there is a problem in that the cut end of the tape remains on the tape holder.

In addition, it is preferable that the binding device be capable of reliably cutting off the vicinity of the winding ends after heating and fusing the ends of both windings of the binding tape. When the tape is held between the tapes, the binding tape is simply stretched, and the tape cannot maintain tension.

Moreover, fitting the push-down piece between the rubber roller and the locking protrusions only causes the tape to be fed out, and it is difficult to create tension in the tape, so as the cutting blade descends, the winding end There was a problem in that there was slack in the vicinity of the section, making it impossible to cut reliably.

In order to solve these problems, the present invention provides a binding tape presser bar at the head between the cutting blade and the welding member, and applies tension to the area near the winding end when cutting the binding tape. In addition, to provide a binding device that ensures that the vicinity of the winding end of the binding tape is cut, and also that after cutting, the cut end on the side of the wound object to be bound escapes from the tape holder. The purpose is to

Means for Solving the Problems In order to achieve the above object, the present invention includes: a heating member installed at a predetermined distance from a tape holder that holds the cut end of a binding tape; a head part that is provided so as to face the heating member, and a fusing member that moves up and down relative to the heating member and cooperates with the heating member to heat and fuse the ends of both windings of the binding tape; A binding device comprising: a cutting blade provided in the head portion and entering between the heating member and the tape holder to cut a portion near the winding end of the binding tape, the binding device comprising: The head part is provided with a binding tape presser bar that presses the vicinity of the winding end of the binding tape between the cutting blade and the fusing member, and furthermore, a binding tape presser bar is provided between the cutting blade and the fusing member, and a binding tape presser bar that presses a portion near the winding end of the binding tape is provided between the tape holder and the heating member. The gap is characterized in that it is an entry space into which the tip of the binding tape presser bar enters.

With this structure, the cut end of the binding tape is held by the tape holder and stretched between the tape holder and the head part, and the object to be bound is half-wound by the lowering of the head part, and the binding tape presser The tip of the rod enters between the heating member and the tape holder and applies tension to the wound end of the binding tape, so the objects to be bound are drawn toward you and the binding tape is tightened around the objects. This reduces the distance between the binding tape and the objects to be bound.

Thereafter, the cutting blade cuts the binding tape, and the fusing member engages with the heating member to thermally fuse the overlapping binding tapes.

When the cutting blade cuts, the cut end on the side of the object to be bound is flipped upward by the pressure of the binding tape presser bar, so that it is not caught in the tape holder.

Furthermore, in this case, since tension is applied to the vicinity of the winding end of the binding tape, the binding tape can be reliably cut without loosening.
