Description
本発明は、ベルト接合装置に関し、特にベルトの端部同士を接合する装置に関する。
The present invention relates to a belt joining device, and more particularly to a device for joining belt ends.
熱可塑性樹脂を主材料とする伝動、搬送ベルトを無端帯状に接合する手段としては、加熱ヒータとプレスとが一体化されたベルト接合装置が開示されている（例えば、特許文献１）。上記ベルト接合装置は、ベルトの両端部を一対の加熱プレス間にセットし、当該加熱プレスによりベルトの両端部を融着して一体化し、その後冷却することにより固形化する。
A belt joining device in which a heater and a press are integrated has been disclosed as a means for joining a transmission and a conveyance belt mainly composed of a thermoplastic resin in an endless belt shape (for example, Patent Document 1). In the belt joining apparatus, both ends of the belt are set between a pair of heating presses, and the both ends of the belt are fused and integrated by the heating press, and then solidified by cooling.
しかしながら上記特許文献１の場合、加熱ヒータとプレスとが一体化されているので、ベルト接合装置を小型化することが困難であるという問題があった。ベルトが使用される現場において、携帯可能なベルト接合装置が用いられている。例えば印刷機や券売機の搬送装置では、狭い空間にベルトが複数列に配置されている。このように使用されているベルトを交換する場合、従来のベルト接合装置では、ベルトの付近に十分なスペースがなくベルト接合装置をベルトの近くに挿入することができないため、搬送装置を印刷機や券売機から一端取り外す必要がある。そうするとベルト交換後、搬送装置を再度印刷機や券売機へ取り付ける必要があるので、余計に作業時間を要し、作業が煩雑になってしまう。
However, in the case of Patent Document 1, since the heater and the press are integrated, there is a problem that it is difficult to downsize the belt joining apparatus. In the field where a belt is used, a portable belt joining device is used. For example, in a transport device of a printing press or a ticket vending machine, belts are arranged in a plurality of rows in a narrow space. When replacing a belt used in this way, the conventional belt joining device does not have enough space near the belt and the belt joining device cannot be inserted near the belt. It is necessary to remove one end from the ticket machine. If it does so, since it is necessary to attach a conveying apparatus to a printing machine or a ticket vending machine again after belt replacement, extra work time will be required and work will become complicated.
本発明は、小型化することができるベルト接合装置を提供することを目的とする。
An object of the present invention is to provide a belt joining apparatus that can be miniaturized.
本発明に係るベルト接合装置は、第１ベルト端部と、第２ベルト端部の両端部を突き合わせて保持する保持体と、前記両端部を厚さ方向に加圧する加圧体とを備えるベルト接合装置であって、前記保持体は、ヒータを着脱自在とする受容部を有することを特徴とする。
A belt joining apparatus according to the present invention includes a belt including a first belt end, a holding body that holds both ends of the second belt end in contact with each other, and a pressure body that pressurizes the both ends in the thickness direction. It is a joining apparatus, Comprising: The said holding body has a receiving part which makes a heater detachable, It is characterized by the above-mentioned.
本発明によれば、ヒータを受容部に挿入して、第１ベルト端部及び第２ベルト端部を加熱することとしたから、小型化することができる。
According to the present invention, since the heater is inserted into the receiving portion and the first belt end and the second belt end are heated, the size can be reduced.

次に本実施形態に係るベルト接合装置１０を用いたベルトの接合方法を説明する。まず第１ベルト端部１６を下型２０Ａの上面に配置し、当該第１ベルト端部１６をベルトクランプ２５及びクランプねじ２６によって下型２０Ａに固定する（図２）。同様に第２ベルト端部１８を下型２０Ａの上面に配置し、当該第２ベルト端部１８をベルトクランプ２５及びクランプねじ２６によって下型２０Ａに固定する。第１ベルト端部１６の先端はＶ字形凹形状、第２ベルト端部１８の先端はＶ字形凸形状に加工されるのが好ましい。 (How to use the belt joining device)
Next, a belt joining method using the
次いで、第１ベルト端部１６と第２ベルト端部１８の間に、接着体３３を配置する。接着体３３としては、熱可塑性樹脂、例えば、ウレタンエラストマー、ポリアミドエラストマー、ポリエステルエラストマー、ポリ塩化ビニル系エラストマー、ポリオレフィン系エラストマーを用いることができる。第１ベルト端部１６及び第２ベルト端部１８の両端面の上側に、シート材２３を介して上型２２を配置する。

本発明は上記実施形態に限定されるものではなく、本発明の趣旨の範囲内で適宜変更することが可能である。
The present invention is not limited to the above-described embodiment, and can be appropriately changed within the scope of the gist of the present invention.
上記実施形態の場合、ヒータとして半田ごて４０を用いた場合について説明したが、本発明はこれに限られず、例えば図７に示すように、柱状の半導体ヒータ４１を用いることもできる。この場合、半導体ヒータ４１の少なくとも先端が、磁性材料で形成されていることにより、磁石３８に引き寄せられ、半導体ヒータ４１を受容部２４に挿入された状態で固定することができる。ヒータは、柱状に限定されず、板状でもよい。板状のヒータを用いる場合、受容部は、当該ヒータが挿入できる立方体状の穴とする。
In the above embodiment, the case where the soldering iron 40 is used as the heater has been described. However, the present invention is not limited to this, and for example, a columnar semiconductor heater 41 can be used as shown in FIG. In this case, since at least the tip of the semiconductor heater 41 is formed of a magnetic material, the semiconductor heater 41 can be attracted to the magnet 38 and fixed in a state where the semiconductor heater 41 is inserted into the receiving portion 24. The heater is not limited to a column shape, and may be a plate shape. When using a plate-shaped heater, the receiving portion is a cubic hole into which the heater can be inserted.
また受容部２４には、図８に示すヒートシンク４３を挿入することとしてもよい。当該ヒートシンク４３は、放熱部４５と、当該放熱部４５と一体に形成された挿入部（図示しない）とを有する。挿入部は、柱状であって、少なくとも先端が磁性材料で形成されている。ベルト接合装置１０は、ヒータで所定時間加熱した後に、挿入部を受容部２４に挿入して、保持体１２とヒートシンク４３を熱的に接続することにより、より速く第１ベルト端部１６及び第２ベルト端部１８を冷却することができるので、ベルトを交換する作業時間をより短縮することができる。
Further, a heat sink 43 shown in FIG. 8 may be inserted into the receiving portion 24. The heat sink 43 includes a heat radiating portion 45 and an insertion portion (not shown) formed integrally with the heat radiating portion 45. The insertion portion has a columnar shape, and at least the tip is formed of a magnetic material. The belt joining apparatus 10 heats the first belt end 16 and the first belt 16 faster by inserting the insertion portion into the receiving portion 24 and thermally connecting the holding body 12 and the heat sink 43 after heating with a heater for a predetermined time. 2 Since the belt end 18 can be cooled, the working time for replacing the belt can be further shortened.
固定部が磁石３８である場合について説明したが、本発明はこれに限らず、係合部でもよい。図９に示すように、係合部としてプランジャー４２を下型２０Ｂに設けてもよい。プランジャー４２は、本体４７と、本体４７内に配置されたコイルバネ（図示しない）と、コイルバネによって本体の先端側へ押し付けられたボール４８とを有する。本体４７は、受容部２４の半径方向に向かって、先端のボール４８が受容部２４内に露出するように下型２０Ｂに固定される。ヒータ（本図には図示しない）は、外周面にボール４８が係合する係合溝が形成されているのが好ましい。受容部２４の一端に挿入されたヒータは、先端部分がボール４８を押し下げ、受容部２４の他端まで到達する。このときボール４８が係合溝に係合することにより、ヒータは受容部２４に固定される。一方、ヒータに引き出す力を加えると、係合溝とボール４８の係合が解除され、ヒータを受容部２４から取り外すことができる。
Although the case where the fixing portion is the magnet 38 has been described, the present invention is not limited to this, and may be an engaging portion. As shown in FIG. 9, a plunger 42 may be provided on the lower mold 20B as an engaging portion. The plunger 42 has a main body 47, a coil spring (not shown) disposed in the main body 47, and a ball 48 pressed against the distal end side of the main body by the coil spring. The main body 47 is fixed to the lower mold 20 </ b> B so that the ball 48 at the tip is exposed in the receiving portion 24 in the radial direction of the receiving portion 24. The heater (not shown in the figure) preferably has an engaging groove on the outer peripheral surface for engaging the ball 48. The tip of the heater inserted into one end of the receiving portion 24 pushes down the ball 48 and reaches the other end of the receiving portion 24. At this time, the ball 48 is engaged with the engaging groove, whereby the heater is fixed to the receiving portion 24. On the other hand, when a pulling force is applied to the heater, the engagement between the engagement groove and the ball 48 is released, and the heater can be removed from the receiving portion 24.
図１０に示すように、係合部としての板状ばね４６を設けてもよい。下型２０Ｃは、受容部２４の下側に設置溝４９が形成されている。当該設置溝４９には、取り付けねじ４４で片持ち梁構造の板状ばね４６が固定される。板状ばね４６は、山形であり、裾の一端が取り付けねじ４４で下型２０Ｃに固定されている。板状ばね４６は、頂部が受容部２４内に露出しており、裾の他端が設置溝に張り出している。ヒータ（本図には図示しない）は、外周面に板状ばね４６が係合する係合溝が形成されているのが好ましい。受容部２４の一端に挿入されたヒータは、先端部分が板状ばね４６を押し倒し、受容部２４の他端まで到達する。このとき板状ばね４６が係合溝に係合することにより、ヒータは受容部２４に固定される。一方、設置溝４９から板状ばね４６を引き出し、係合溝と板状ばね４６の係合を解除することにより、ヒータを受容部２４から取り外すことができる。
As shown in FIG. 10, a plate spring 46 as an engaging portion may be provided. The lower mold 20 </ b> C has an installation groove 49 formed on the lower side of the receiving portion 24. A plate-like spring 46 having a cantilever structure is fixed to the installation groove 49 with a mounting screw 44. The plate spring 46 has a mountain shape, and one end of the skirt is fixed to the lower mold 20 </ b> C with a mounting screw 44. The top of the plate spring 46 is exposed in the receiving portion 24, and the other end of the skirt projects into the installation groove. The heater (not shown in the figure) preferably has an engaging groove that engages with the plate spring 46 on the outer peripheral surface. The heater inserted into one end of the receiving portion 24 reaches the other end of the receiving portion 24 by pushing down the plate spring 46 at the tip portion. At this time, the heater is fixed to the receiving portion 24 by the plate spring 46 engaging with the engaging groove. On the other hand, the heater can be removed from the receiving portion 24 by pulling out the plate spring 46 from the installation groove 49 and releasing the engagement between the engagement groove and the plate spring 46.
