Description

[Detailed description of the invention] ゛The present invention relates to a wrapping device using plastic tape.

In recent years, it has become common practice to stack multiple tubes of seaweed or other bundles, bundle them with tape made of heat-adhesive material, and heat-seal the ends of the tape to bind them together. Since the banding device is used for high-speed, large-volume processing, it has a complicated structure, is large in size, and is expensive. Therefore, it is not necessarily suitable for use in companies that do not need to perform such high-speed and large-volume bundling.The present invention was made based on the above circumstances, and has a simple structure and easy operation. The object of the present invention is to obtain a banding device that can be supplied at low cost.

Hereinafter, the present invention will be described in detail with reference to six drawings. FIG. 1 is a schematic front view showing the whole of one embodiment of the present invention.

In addition, pillar 2
A stopper 15 is provided for regulating the position of the U-shaped frame 4 and therefore the position of the U-shaped frame 4 against the spring 6.

Below, the tape cutting and fusing head 13 is shown in FIGS. 3 and 4.
, details of the tape holding section 14 will be explained.

The head J3 is attached to the inner surface of the end of the leg on the side opposite to the pivot point of the U-shaped frame 4, has a tape passage 16 parallel to the leg, and has a tape passage 16 parallel to the leg when viewed from a direction perpendicular to the surface of the leg. The head frame 17 has an inverted U-shape, and an inclined cam 17a is provided on one side of the U-shaped frame leg at the lower end of both side plates of the head frame 17 to gradually narrow the center of the head frame 17 downward. Furthermore, two long holes 18 parallel to the leg pieces are provided in each of the side plates, and guides 20 protruding from both sides of the tape holding plate 19 are provided in the long holes on one side of the leg. Nine' guides 22 are slidably engaged with the elongated holes, respectively, protruding from both sides of a pressure bonding plate 21 for heat fusion.

Note that a guide rod 23 is attached to the upper end of the presser plate 19, and this guide rod 23 slidably passes through the slide block 24. In the figure, 23a indicates the head of the New Year's tree, and 24a indicates a coil spring that applies a downward spring force to the slide block 24. In addition, the guide rod 23
A spring 25 is attached to the holding plate 19, and this spring applies a downward spring force to the holding plate 19.

Further, the upper end of the pressure bonding plate 21 is fixed to the lower surface of the slide block 24.

Further, between the inner surfaces of both side plates of the head frame 1'I, a tape pushing claw 26 located on the tape passage 16 side is suspended from the lower end, and a six cutter support member 27 is fixed to the bridge, and the tape pushing claw 26 of this member 27 is opposite to the pushing claw 26. A tape cutter 28 that hangs downward from the push-in claw 26 is attached to the side surface. The lower end of the tape cutter 28 is a cutting edge.

Also, there is a tape press plate on the inside surface of the tape press plate 19!
The tape bending claw 29, whose lower end protrudes from the lower end of the tape 9 and is positioned slightly away from the inner surface, is attached.

Further, rubber plates 30 and 31 for holding are fixed to the lower end surfaces of the tape holding plate 19 and the pressure bonding plate 21.Furthermore, the tape holding portion 14 is constructed as follows.

That is, when the U-shaped frame 4 is lowered by operating the handle 5 and the tape cutting and fusing head 13 is perpendicular to the upper surface of the machine frame 1, it almost faces the tape cutter 28 of the tape cutting and fusing head 13. A tape support plate 32 having one end is provided on the upper surface of the machine frame, and a wall body 33 hanging down from the other end of the support plate, a wall body 3-4 facing the tape pressure bonding plate 21, the tape support plate 32 and Together with the side plates 35 connecting the sides of the two walls 33 and 34, a tape holding frame 36 is constructed, and within this frame 36 there is a bridge between the inner surfaces of the side plates 35, and one end is approximately connected to the tape cutter 28. A slide support stand 37 is provided which faces each other and whose other end is slightly spaced from the inner surface of the wall body 33.

Further, the tape support plate 32 has one opening edge that is substantially opposite to the inner edge of the rubber plate 30 at the lower end of the tape holding plate 19, and the other opening edge that is closer to the tape cutter 28 than the tape pushing claw 26. Moreover, the other opening edge is provided with an opening 38 that opens upward. Further, a heater 39 is provided on the upper surface of the wall body 34 at a position facing the rubber plate 31 on the lower surface of the tape pressure bonding plate 21. .

In the gap formed by the tape support plate 37 and the tape support plate 32, the cross section perpendicular to the drawing forms a U-shape, and the ends of the side plates on the wall body 34 side have an arc-shaped convex curved surface. In the bottom plate 40b of the L slide 40 into which the slide 40 formed with the slide 40a is slidably inserted, a bending plate spring 41 whose both ends are parallel connects one end to the top opening of the opening 38. The edge side is attached to the tape support plate 32 in contact with the lower surface thereof. Note that an upward force is applied to the end portion by a coil spring 42. Further, a guide rod 43 is attached to the side plate of the slide 40 and slidably passes through the wall 33, and a coil spring 44 is generally attached to this guide rod <3 between the side plate and the inner surface of the wall 33. has been done.

With the apparatus of the present invention having the above-mentioned structure, articles are bound in the following manner. That is, the state in which the U-shaped frame 4 is in the upper position as shown in FIG.
Tape guide 4a.

A portion of the bent leaf spring 41 of the tape holder 14 and the tape support plate 3 in the state shown in FIG.
2. The terminal is held between 1 and the lower surface. However, it goes without saying that in this state, the tape cutting and fusing head 13 is not in the state shown in FIGS. Therefore, the tape T is
As shown in FIG. 1, a stretched section T' is formed between the lower end of the tape cutting and fusing head 13 and the tape holding section 14.

A bundle A of articles is placed on the end of the upper surface of the machine frame 1 on the side opposite to the support column, and the front surface of the bundle A is brought into contact with the spreading section T' to push the bundle A toward the support column 2. Then, the tape T is attached to the tape tape 1.
The tape-cutting and fusing head 1
It has a bent shape consisting of a portion reaching the lower end.

Here, the U-shaped frame 4 is lowered. During this descent, 1
．． The lower end of the tape pressure bonding plate 21 of the tape cutting and fusing head 13 hooks the tape extending from the front side of the bundle A to the lower end of the tape cutting and fusing head 13, and descends while feeding out the tape from the tape pad 10. Therefore, as shown in FIG. 3, when the rubber plate 3o at the lower end of the tape presser plate 19 of the tape cutting and fusing head 1-3 comes into contact with the tape support plate 32, the end is bent by the leaf spring 41. The tape held between the lower surface of the tape holding plate 32 and the lower surface of the tape holding plate 32 is made to go around the bundle A almost once, and the side adjacent to the tape pad 1oK passes through the gap between the rubber plate 31 and the heater 39, and then passes between the rubber plate 3o and the tape support plate 32. It will be sandwiched between. As the U-shaped frame 4 continues to descend, the tape holding plate 19 slides in the elongated hole 18 against the spring 25, so that the rubber plate 31 of the tape pressure bonding plate 21 is placed between the tape and the heater 39. One end of the tape and the part of the tape guide lo are pressed together and the two are thermally fused.

At this time, the tip of the tape bending claw 29 creates a crease in the tape.

As the U-shaped frame 4 continues to descend, only the blade frame 17 of the tape cutting and fusing head 13 descends against the spring 24aK, as shown in FIG. By this descent, the lower end of the tape cutter 28 first comes into contact with the tape and cuts it.
At the same time, the cam 17a on the side plate of the head frame 17 moves to the curved surface 40 of the slide 40. Press a to move the slide 40 back toward the wall 33 against the spring 44. As a result, the cut remaining piece of tape that was held between the bending leaf spring 41 and the lower surface of the tape support plate 32 is released and falls. During the above-mentioned lowering, the tape pushing claw 26 pushes the end newly formed by cutting the tape into the tape holder frame 36.

When the U-shaped frame 4 is raised, the tape cutting and fusing head 13 is separated from the upper surface of the machine frame 1, and the slide 40 returns to its old position by the force of the spring 44. The leaf spring 41 accompanies the pushed-in tape end and clamps it between it and the lower surface of the tape support plate 32.

In this way, one banding operation is completed, and the apparatus returns to the state shown by the solid line in FIG. 1.

As is clear from the above, the device of the present invention does not require any power, can easily perform banding, and has a relatively simple structure and can be provided at a low price.
It is suitable for applications that do not necessarily require high-speed, large-volume processing, such as conventional complicated and expensive banding devices.
