Description

[Technical field]

[0001] The present invention relates to a cable tie excess cutting tool and cutting method that can cut off excess cable ties with a simple operation, and can remotely cut off excess cable ties used at high altitudes, for example, from the floor. [Background technology]

[0002] Patent Document 1 describes a tool for remotely tying cable ties when bundling wiring cables or the like at high altitudes. This tool fixes the locking part of the cable tie to the tool body, grips the band part of the cable tie with an existing gripping tool, and operates the existing gripping tool to insert the band part into the locking part and tighten it.

[0003] Meanwhile, Patent Document 2 describes a band cutting device that cuts off excess length of a cable tie. This cutting device is generally pistol-shaped and includes a grip that is held by hand, a barrel that extends forward from the top of the grip, and an operating lever that corresponds to the trigger of a handgun. When the operating lever is pulled with the cable tie fastened, the excess length of the band is cut off.

[0004] The structure of the cable tie made of synthetic resin material is such that the base end of the band part that tightens the member is provided with a lock part that engages and fixes the band part. Therefore, when the cable tie is tightened, the tip of the band part that is engaged with the lock part remains as an excess part. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent No. 5295323 [Patent Document 2] JP 2018-30638 A Summary of the Invention [Problem to be solved by the invention]

[0006] The tool in Patent Document 1 tightens the cable tie by remote control, but the excess length of the cable tie is left as is after tightening. As a result, this excess length hangs down from the locking part of the cable tie.

[0007] On the other hand, the band cutting device described in Patent Document 2 is a device that cuts off the excess length of a cable tie. However, this device is configured to cut off the excess length of a cable tie by inserting the excess length of the cable tie into the inside of the retraction port of a pistol-shaped barrel and pulling an operating lever equivalent to the trigger of a handgun. Therefore, in order to introduce the tip of the band part into the small retraction port at the tip of the barrel, it is necessary to operate it near the cable tie. Therefore, in order to cut off the excess length of a cable tie used at high altitudes, a worker must use a stepladder or the like to go near the cable tie and cut it.

[0008] Therefore, the present invention was created to solve the problems of the conventional art, and aims to provide a cable tie excess cutting tool and cutting method that can cut off the excess length of a cable tie with a simple operation, and that can remotely cut off the excess length of the cable tie from the floor side, even when the cable tie is tightened at a high place.

[0019] The cutting tool of the present invention is a cable tie cutting tool for cutting off an excess portion of a band portion S1 of a fastened cable tie S. A tool body 10 of the present invention includes a cutting blade 1 and a holder 2.

[0020] The cutting blades 1 are a pair of cutting members closely facing each other on both wide sides of the band portion S1 protruding from the locking portion S2 of the cable tie S. The cutting blades 1 are installed so that their cutting edges, which are longer than the width of the face of the band portion S1, are approximately parallel to both sides, and are closely facing each other with a minimum gap between each cutting blade 1 that allows the band portion S1 to be inserted from the side (see FIG. 4).

[0021] The holder 2 is a pair of members arranged on the tip side of the band portion S1 relative to the cutting blade 1, and holds both sides of the band portion S1 in a freely crimpable manner. The holder 2 shown in the figure faces both sides of the band portion S1 with its crimping surface facing them so as to be freely opened and closed (see FIG. 4).

[0022] Furthermore, a crank body 3 is provided for opening and closing the holding body 2, and the band portion S1 is crimped and held by the holding body 2 when the crank body 3 is operated (see Figs. 4 and 5).

[0023] In the illustrated example, a crank body 3 is provided in which a slider 3C moves to move the crank body 3 horizontally (see Figs. 4 and 5). The crank body 3 includes a crank 3A, a connecting rod 3B, a slider 3C, and a groove 3D. When the crank 3A is lowered with the pivot shaft 3E as a fulcrum, the slider 3C moves to move the crank body 3 horizontally.

[0024] That is, the band portion S1 is inserted between the pair of holders 2 in an open state (see FIG. 4). Next, when the crank 3A is lowered in this state, the connecting rod 3B swings about the swing shaft 3E as a fulcrum, and the slider 3C fixed to the connecting rod 3B slides in the groove 3D (see FIG. 5). This groove 3D is provided inside the holder 2, and when the slider 3C moves in the groove 3D of the holder 2, the space between the opposing holders 2 opens and closes.

[0025] The crank body 3 is not particularly limited to the illustrated example. It can be changed arbitrarily as long as it is configured to hold the interval between the holders 2 openable and closable. For example, the upper end sides of the holders 2 can be opened and closed, and when the holders 2 are pulled down at the same time, the upper end sides of the holders 2 close to hold the band portion S1 (see FIG. 9). It is also possible to configure the upper end side of the crimping plate body 2A to close at the position where the holders 2 are provided in the same configuration as in FIG. 9 (see FIG. 10). In this way, the structure of the crank body 3 can be changed arbitrarily. Furthermore, when the tool main body 10 described later is directly operated, it is also possible to change to a structure in which the holders 2 are opened and closed by directly operating them without using the crank body 3 (not shown).

[0026] The tool body 10 is provided with an introduction portion for introducing the band portion S1 between the cutting blades 1 and the holder 2. In the illustrated example, an introduction groove portion 11 for introducing the band portion S1 of the cable tie S from the side is provided between the cutting blades 1. When the band portion S1 is introduced into this introduction groove portion 11, the band portion S1 is introduced between the cutting blades 1 and between the holders 2. In the illustrated example, the opening side of the introduction groove portion 11 is formed wide, and the introduction groove portion 11 is formed so as to become narrower toward the back (see FIG. 1). The band portion S1 introduced along this introduction groove portion 11 is introduced between the cutting blades 1 and the holders 2 that are finally connected to each other (see FIG. 4). It is also possible to insert the band portion S1 from above the cutting blades 1 without providing this introduction groove portion 11.

[0027] The band portion S1 is crimped and held by the holder 2 (see Figure 5), and when the tool body 10 is rotated in this state (see Figure 6), a slit is made in the band portion S1, and this slit is twisted and cut between the cutting blades 1 (see Figure 7).

[0028] 8 shows the process in which the twisted band portion S1 is cut by the cutting blade 1. Fig. 8 (a) shows the state in which the band portion S1 is inserted between the cutting blades 1 and the holder 2 of the tool body 10. At this time, the holder 2 holds the band portion S1 by pressing it against the underside of the cutting blade 1.

[0029] 8(b), the tool body 10 is rotated while the band portion S1 is held. In this state, the band portion S1 on the cutting blade 1 side of the band portion S1 is fixed to the lock portion S2, so the band portion S1 is twisted from the side of the band portion S1 held by the holder 2 to the band portion S1 toward the cutting blade 1. Then, the band portion S1 twisted between the cutting blades 1 is gradually cut off from the portion that contacted the cutting blade 1.

[0030] Finally, as shown in FIG. 8(c), when the tool body 10 is rotated, the band portion S1 is cut.

[0031] In this way, in the present invention, by introducing the band portion S1 into the introduction groove portion 11 of the tool body 10 and rotating the tool body 10 while fixing the band portion S1 with the holding body 2, the excess portion of the band portion S1 can be cut off extremely easily.

[0032] Furthermore, by attaching the tool body 10 to the tip of the operating pole 30, it becomes possible to cut off the excess length of the band portion S1 of a cable tie S that has been tightened at a high place with a simple operation from the floor side (see Figure 11).

[0033] In the illustrated example, the tool body 10 is attached to the tip of the operating pole 30, and is equipped with a string-like body 20 for remotely controlling the crank body 3 (see FIG. 11). The string-like body 20 is wound around the operating ring body 40 so that its length can be adjusted freely, and is arranged so that the connecting rod 3B of the tool body 10 is lowered when the operating ring body 40 is pulled down.

[0034] The tool body 10 can also be attached to another binding tool 50 that binds cable ties S (see FIG. 12). In the illustrated example, the tool body 10 is shown attached to the side of the binding tool 50 that is attached to the tip of the operation pole 30. By attaching the tool body 10 to the binding tool 50 that binds cable ties S in this way, it becomes possible to rationally perform operations from binding the cable ties S to cutting off excess length by operating a single operation pole 30.

[0035] Next, a process of cutting off the excess length of the band portion S1 using the tool body 10 attached to the operation pole 30 will be described. First, the band portion S1 is introduced into the introduction groove portion 11 of the tool body 10 from the side (see FIG. 1). Even if the cable tie S is used at a high altitude, the operation of the operation pole 30 can easily introduce the straight band portion S1 into the introduction groove portion 11 of the tool body 10. Moreover, the band portion S1 introduced into the introduction groove portion 11 eventually moves to a position between the cutting blade 1 and the holder 2.

[0036] Next, the operating pole 30 is raised to bring the position of the cutting blade 1 of the tool body 10 closer to the position of the locking portion S2 of the cable tie S (see FIG. 2). At this time, since the cutting blade 1 is provided near the upper end of the tool body 10, the cutting blade 1 can be moved close to the locking portion S2 (see FIG. 4).

[0037] After adjusting the position of the cutting blade 1, the string-like body 20 is pulled down to lower the connecting rod 3B (see FIG. 3). Then, the holding body 2 linked to the crank body 3 presses and holds both sides of the band portion S1 (see FIG. 5). While the string-like body 20 is being pulled down in this manner, the holding body 2 holds the band portion S1.

[0038] Then, with the holding body 2 holding the band portion S1, the operating pole 30 is operated to rotate the tool body 10 in one direction (see FIG. 6), resulting in the excess length of the band portion S1 being cut off (see FIG. 7).

[0039] The embodiments of the present invention are not limited to the illustrated examples, and design changes are free within the scope of the present invention. [Explanation of symbols]
