Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a binding device that uses a heat-adhesive tape as a binding tape.

BACKGROUND ART Conventionally, there has been a binding device for binding objects such as green onions, and this conventional binding device uses a single-sided adhesive tape coated with an adhesive on one side as a binding tape. However, this single-sided adhesive tape has a drawback in that its adhesive strength decreases when foreign matter such as dust, dust, water droplets, etc. adhere to the adhesive. Therefore, when objects to be bound are bound using a single-sided adhesive tape to which such foreign matter is attached, the objects may not be bound. Furthermore, in the case of objects to be bound, such as green onions, which are served at the table, the adhesive is attached to the objects, which is not preferable from a sanitary standpoint. Furthermore, there is a drawback that the adhesive sticks to the objects to be bound, making it difficult to perform tight winding.

The engagement member 58 is biased to rotate in the direction of arrow G in FIG. 3 by the spring 4s, and its projection 38b comes into contact with the lower surface of the guide plate 54 and stops rotating at a predetermined position. There is. A support pin 44 is embedded in the rotation shaft 37, and this support pin 44 contacts the support member s2 to move the support member 3f and the heating member 27 up and down. The lower surface t9B of the side frame 19 is brought into contact with the upper surface of the vertically movable rod 51, and the vertically movable rod 31 is moved up and down by this side frame 19.

Here, the lower surface 193 of the side frame 19 is configured to come into contact with the vertically movable rod 31 after the pressure bonding member 20 comes into contact with the pressure receiving surface 24B. A bottle 45 is installed on the side plate 21,
When the vertically movable member 51 is lowered a predetermined distance, one end of the intermediate member 36 abuts against the pin 45, and the intermediate member 34 is rotated in the direction opposite to the arrow [direction] in FIG. Then, the engagement between the intermediary member 56 and the engagement member 38 is released.

Next, the operation of the binding device according to the present invention configured as described above will be explained.

In the process of placing the objects 29 to be bound on the mounting table 50, the heat-sealing tape 6 is pulled out to a desired length. Next, the handle 15 is operated to tilt the binding arm 3 in a direction in which the head portion 12 approaches the tape holding device 10. As a result, the object to be bound is 2! A heat fusion tape 6 is wound around. Then, the open end portions of both volumes of the heat fusion tape 6 are connected to the pressure bonding member 2o and the pressure receiving member 2.
It is held between 4. After that, the lower surface 1 of the side frame 19?
i comes into contact with the vertically movable rod 31, and at the same time, the tapered surface 19b of the side frame 19 comes into contact with the clamping rod 25, and the clamping rod 25 separates from the tape holder 23. By further pushing down the binding arm 4, the vertically movable rod 31 is lowered by being pushed downward by the side frame 19, and the intermediary member 66 engages with the retaining member 58, and the retaining member 38 is moved as shown in FIG. It will rotate in the direction opposite to the direction of arrow G. Therefore, the rotation shaft 57 integrated with the coupling member 38 rotates in the same direction, and the support bin 44 lifts the heating member 27 together with the support member 52. As a result, the open ends of both volumes of the thermal adhesive tape 6 are heated while being subjected to pressure, and the open ends of both volumes are fused. In addition, the heat-sealing tape 6 is cut by the cutting blade 16 during this fusing acid. When the vertically movable rod 31 further descends, the intermediate member 56 comes into contact with the pin 45, and the intermediate member 56 rotates in the direction opposite to the direction of arrow W in FIG. 3, thereby securing the intermediate member 56 and the retaining member 3B. The connection is canceled. Therefore, the retaining member 58 rotates in the direction of arrow G in FIG. 5, and the heating member 27 descends, thus completing the fusion process. Note that when the binding arm 3 stands up, the vertically movable rod 51 returns to its original position by the urging force of the spring 40.

According to this embodiment, fusing can be performed by simply adding a heating member and a means for vertically moving the heating member to the tape holding device of the conventional structure, so that the conventional structure can be fused without making any major changes. A binding device can be manufactured. Further, since the heating member 27 and the pressure bonding member 20 are configured to press the open end portions of both volumes and fuse them together, the welding can be reliably performed. Furthermore, since the pressure bonding member is made of rubber, even a thin heat-adhesive tape can be securely clamped.

FIG. 7 shows another embodiment of the vertical movement means according to the present invention, in which the heating member 27 is moved vertically without intervening the intermediary member 56, and the vertical movement rod 5
1, and the other configurations are the same as those of the previous embodiment, so the same components as those of the previous embodiment are given the same reference numerals, and detailed explanation thereof will be omitted.

FIG. 8 shows still another embodiment of the binding device according to the present invention, in which the pressure receiving member 24 is moved up and down instead of moving the heating member 27 up and down, and the other configuration is as described above. Since it is almost the same as the embodiment, the same components as the embodiment are given the same reference numerals and only the different points will be explained. In FIG. 8, there are spring receivers 46 on both sides of the pressure receiving member 24.
A spring 47 is formed between the spring receiver 46 and the base 1.
is interposed, and the pressure receiving member 24 is urged upward by the spring 47GC, so that the upper surface 273 of the heating member 27 is separated from the pressure receiving surface 24fi by a predetermined distance.

The lower surface of the side frame 19 is brought into contact with the upper surface of the spring receiver 46, and the biasing force of the spring 47 is applied to the retaining rod 15.
After both winding ends of the heat-sealing tape 6 are clamped between the fixing rod 15 and the pressure receiving member 24, the pressure receiving member 24 is pressed by the side frame 19. is made to descend.

In the case of the above embodiment, there is a risk that the lead wire connecting the heater 28 to the power source is bent by the vertical movement of the heating member 27, resulting in breakage, but in the case of this embodiment, the heating member 27 is fixed. Therefore, there is no risk of that happening. Further, its configuration is also simplified compared to the embodiment described above.

Although the embodiments have been described above, the present invention is not limited thereto and includes the following.

+11 In the embodiment, a current is constantly supplied to the heating member 27 during use, but after the end portions of both rolls of the heat-sealing tape 6 are clamped by the fixing rod 15 and the pressure-receiving member 24, It is also possible to construct the heating member 27 so that a current sufficient to fuse the ends of both turns is passed through the heating member 27.

(2) In the embodiments, the heating member 27 is provided in the tape holding device 10, but the heating member 27 may also be provided in the head portion 12.

(3) In the embodiment, an example in which the present invention is applied to a manual binding device has been described, but the present invention can also be applied to an automatic binding device that can automatically bundle objects. ) In the embodiment, the heater is inserted into the heating member, but the heater and the heating member may be integrally molded.

Since the present invention is configured as described above, it has the following effects.

(1) Since the objects to be bound can be bound using a thermal adhesive tape, it is possible to bind the objects to be bound without being affected by the quality deterioration of the binding tape as in the past.

(2) Since it is possible to use a tape in which the adhesive does not adhere to the objects to be bound, it is also preferable from a hygienic point of view.

(3) Since no adhesive is applied, it is possible to tighten the binding tape tightly when wrapping the binding tape around the object to be bound.
