Next, by turning the object A counterclockwise in the figure or by turning the casing 1 clockwise, the tape 4 is wrapped around the object A as shown in FIG. After winding the object A several times, the object A is pulled out from the object insertion section 7, and the tape 4 is inserted into the tape end holding member 8 from the opening 8A of the member 8, as shown in FIG. 8C. Then, the tape 4 is cut with the cutting blade 6. Cutting blade 6
The cut tape 4 sticks to the tape holding surface 8B of the tape end holding member 8 due to the reaction at the time of cutting, as shown in FIG.

Figures 4 to 6 show an embodiment of a hand-held binding device that can be operated with one hand according to the present invention, and in the figures, the same reference numerals as in Figures 1 to 3 are the same as in the above embodiment. A cutting blade 6 is provided in front of the wound body 4A of the single-sided adhesive tape 4, and a binding object insertion portion 7 is formed between the cutting blade 6 and the wound body 4A, and a binding object insertion part 7 is formed between the cutting blade 6 and the wound body 4A. This embodiment is similar to the embodiment described above in that a tape end holding member 8 is provided between the insertion portion 7 and the cutting blade 6.

Here, the object insertion opening 7A formed in the upper part of the object insertion part 7 is normally closed by a clamping device 9 consisting of a pair of clamping plates 10 and 11 having spring properties. .

Further, the tape end holding member 8 has a tape holding surface 8
It has a tape pressing piece 12 that comes into elastic contact with B.

Furthermore, here, the object to be bound A is placed in the casing 1.
A push handle 13 is provided for pushing the object into the object insertion section 7. The push handle 13 is composed of a pair of upper and lower clamping rods 14 and 15, and the proximal ends of both clamping rods 14 and 15 are rotatably supported by the casing 1 via a shaft 16.
A spring 17 is provided between the lower clamping rod 15 and the casing 1 to push the clamping rod 15 upward, and a spring 18 is provided between the clamping rods 14 and 15 to push them apart. It is being A recess 19 into which the object to be bound A can be inserted is formed between the tips of the two clamping rods 14 and 15.

Furthermore, as shown in FIG.
may be used as a fixed plate, and the other clamping plate 11 may be used as a spring member.

The clamping device 9 may be provided only on either the clamping plate 10 or 11.

The tape end holding member 8 may be provided on the lower clamping rod 15.

In addition to the above, the tape end holding member may have a clamping force sufficient to prevent the tape from coming off from the holding member when the object to be bound is inserted into the object insertion portion. Good too.

For example, as shown in FIG.
The cutting blade 6 may be configured with a needle such that the needle 8 pierces the tape 4 when the cutting blade 6 cuts the tape 4 . In this case, by appropriately setting the shape of the needle 8, the strength of the tape 4, etc., the tape 4
The end of the tape 4 can be moved toward the insertion section 7 while the needle hole is expanded in the longitudinal direction, or the tape 4 can be fixed by the needle 8.

The tape end holding member may be omitted. In this case, if the adhesive strength of the tape is increased, the cut end of the cut tape 4 will be attached to and held by the cutting blade.

As described above, in this embodiment, the object A is pushed into the object insertion part 7 through the object insertion opening 7A, and then pulled out from the object insertion part 7 toward the object insertion opening 7A. Then, wrap the end of the cutting blade side tape in the direction where the wound body side tape is located and adhere it to the wound body side tape.
1 to shrink the object insertion part in the longitudinal direction of the single-sided adhesive tape 4 to elastically squeeze the binding part of the objects A and to adhere the single-sided adhesive tape 4 to the objects A. This saves the effort of wrapping the single-sided adhesive tape A. In addition, if a bouquet of elongated vegetables such as chives or carnations is pressed too hard, it will be damaged and its commercial value will be lost. Pressure is applied to the extent that adhesive tape 4 is bonded, and vegetables and bouquets can be bound without being damaged. Furthermore, extremely thin objects A such as wires can be bound without being bent during binding, and even if the objects are formed in an annular shape, the working operation moves the objects between the object insertion opening 7A and the object insertion opening 7A. It can be tied and taken out simply by reciprocating movement between the parts and the parts, making it easy to work.

The clamping device is provided with at least one clamping member whose one end is fixed to the casing and is elastically movable in the longitudinal direction of the single-sided adhesive tape, and the clamping member connects the object insertion portion to the bundled object. A binding object insertion opening connected to the binding object insertion part and expanding outward is integrally formed, and the elastic force of the clamping member allows the binding object insertion part to be inserted in the longitudinal direction of the single-sided adhesive tape. By biasing the single-sided adhesive tape in the direction of contraction, the work of wrapping the single-sided adhesive tape around objects to be bound can be done easily and quickly, and the objects to be bound can be elastically held by the clamping member of the clamping device. At the same time, since the single-sided adhesive tape is pressed toward the object to be bound, binding with the tape can be performed reliably. By simply holding the object to be bound by the clamping device, the tape end located on the cutting blade side with respect to the object to be bound wraps around to the tape side located on the winding body side, and the tape is bonded to the outer periphery of the object to be bound. The work of wrapping the single-sided adhesive tape around the objects to be bound can be saved, and work efficiency is improved, such as by being able to bind the objects without rotating them once.
Moreover, the object insertion part and the object insertion opening connected thereto are integrally formed by the clamping member, and the object insertion part is elastically biased in the direction of shrinking in the longitudinal direction of the single-sided adhesive tape. As a result, there are no rotating parts in the clamping device, the shape and structure of the clamping device is simplified, the binding device is simplified, manufacturing is easier, mass productivity is improved, durability is improved, and costs are reduced. descend.

Furthermore, for binding bouquets of slender vegetables such as chives and bouquets such as carnations, a clamping device can be used to bind slender vegetables or bouquets without damaging the bouquets. However, by pushing and pulling up the objects, it is possible to bind the objects without bending them, and it can be applied to a wide range of objects.
