Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cable end processing jig, and more particularly to a flat tail cable end processing jig for elevators.

[0002]

[Prior Art]

 The work of cutting and stripping the cable sheath for cable end processing has been done by hand using a cutter knife. However, the work of cutting and stripping the cable sheath with a cutter knife was not a dangerous flash, and the core of the cable was often damaged.

As an attempt to remove the end of the cable using a jig, a wire sheath as shown in FIG. 3 of Japanese Utility Model Publication No. 48-32538 is used to lengthen the wire sheath by using a slitting machine. A method is known in which a V-shaped piece is cut parallel to the direction, and the end portion is peeled off by using the cut portion with an electric wire sheath peeling tool described in Japanese Utility Model Publication No. 51-36690.

In Japanese Utility Model Laid-Open No. 56-80621, a pair of rolls are provided so as to face each other, each of which has a disc-shaped cutting tool that is circumferentially projecting and aligned with each other. A coated wire stripping device is described, in which a coated wire is placed between them and at least one of the rolls is driven to feed the coated wire to cut the coating of the wire. This device has the drawback that it is difficult to prevent the wire from meandering, and the wire to be processed is defined by the size of the roll, so it cannot be said to be an efficient terminal processing jig.

A simple explanation of cutting the cable sheath described in Japanese Utility Model Publication No. 48-32538 with reference to FIG. 3 is to place an electric wire in a groove 17 provided in a base 15 in the drawing and A lid 16 having a cutting blade 19 arranged in a V shape at a position overlapping the electric wire on the base 1 is connected by a hinge 18, and the lid 16 is placed on the base 15 by a grip 21.

The electric wire is placed in the groove 17, the lid 16 is closed, and the electric wire sheath is made parallel to the longitudinal direction by the V-shaped cutting blades 19 provided on the lid 16 by pulling the electric wire by hand. Can be cut at V. The cutting blade 19 is fixed to the lid 16 with a fixing member 20.

[0007] The electric wire sheath cleaving machine described in Japanese Utility Model Publication No. 48-32538 is used to cleave the electric wire sheath into a V-shape, and the cutting portion is used to describe the utility model Japanese Utility Model Publication No. 51-36690. The end stripping method of the wire that is stripped with a wire sheath stripping tool may be applicable to small diameter cables, but it is not applicable to large diameter cables such as elevator tail cables. Have difficulty.

However, for the processing of a large-diameter cable end, manually cutting the cable sheath by using a cutter knife is a heavy labor and a very dangerous work.

[0009]

[Problems to be solved by the device]

 The object of the present invention is to solve the above-mentioned drawbacks of the prior art and to cope with a wide range of sizes and types of cables, and to have versatility, especially for large diameter cables such as flat tail cables for elevators. An object of the present invention is to provide a terminal processing jig suitable for such terminal processing of cables and capable of significantly improving workability.

[0010]

[Means for Solving the Problems]

 The above-mentioned problems can be solved by the terminal processing jig of the present invention shown below.

That is, (1) a cable is sandwiched between a roll that holds the upper surface of the cable and a roll that supports the lower surface, one or both of the above rolls is driven to feed the cable, and rolls are also provided on the left and right sides of the cable. Prevents lateral movement of the cable feed, is positioned above the cable, is supported by the side plate of the jig in front of or behind the rolls in the traveling direction of the cable, and horizontally moves up and down to adjust the adjustment. A cable-end working jig with at least one slitting blade arranged parallel to the longitudinal direction of the cable, which is arranged on a possible horizontal bar.

Further, (2) the cable is sandwiched between a roll that holds the upper surface of the cable and a roll that supports the lower surface, and one or both of the rolls is driven to feed the cable. It prevents lateral swaying of the feed, is located above the cable, is supported by the side plate of the jig in front of or behind the rolls in the traveling direction of the cable, and can be vertically moved across the jig. At least one slitting blade placed parallel to the longitudinal direction of the cable, which is arranged on the horizontal bar, forms an angle of not less than 15 ° and not more than 60 ° with the horizontal plane including the horizontal bar that traverses the jig. In a preferred embodiment, a cable terminal processing jig is characterized.

The cable end processing jig of the present invention is particularly effective when applied to the processing of flat cables, which are often used in elevator tail cables, but the circular work is also applicable to processing of shaped cables.

In addition, the cable terminal processing jig of the present invention is such that the distance between the roll that holds the upper surface of the cable and the roll that supports the lower surface, the distance between the left and right support rolls, and the sheath slit according to the diameter and height of the fed cable The position of the horizontal bar supporting the blade can be changed appropriately. . Furthermore, the sheath cutting blade can adjust the biting depth and angle of the cable sheath.

The number of blades that can be installed on the horizontal bar supporting the sheath cutting blade of the cable terminal processing jig of the present invention is arbitrary. Usually, two or three pieces are installed, but when the load for tearing is large, it may be done with one piece. In such a case, work is performed by changing the position of the blade for the same cable. The ripping work is repeated three to three times. In addition, the same sheath cutting is performed on the back surface to separate the sheath, which facilitates the work. In addition, when it is disadvantageous to cut even the inclusions at one time for the cable in which the inclusions are enclosed, it is possible to perform a work method in which the same place is cut twice.

【Example】

 Fig. 1 shows an example of a cable terminal processing jig of the present invention as a front view in the case of terminal processing of a flat tail cable for an elevator. An embodiment of the cable end processing jig of the present invention will be described below with reference to FIG. 1, but the present invention is not limited to the following description.

(Embodiment 1) In FIG. 1, a flat tail cable 11 is constituted by eight insulated wire cores 12 which are loosened by an intervening member 13 and wrapped in a sheath coating 14. The flat tail cable 11 is sandwiched between the driving lower roll 2 and the auxiliary upper roll 3 from the back of the cable terminal processing jig 1 (behind the paper surface) to the front, and is guided by the left and right support rolls 4 to be processed and cured. The lower drive roll 2 is driven into the tool 1 using the drive handle 10 and fed.

The space between the lower drive roll 2 and the upper auxiliary roll 3 (pressure for holding the flat tail cable 11) is adjusted by the upper roll adjusting handle 5. Further, the position adjustment of the left and right support rolls 4 that guide the left and right displacement of the cable 11 is performed by the roll interval adjustment unit 6.

The sheath 7 of the flat-type tail cable 11 is split and the blade 7 is adjustably attached to the horizontal bar 8. The adjusting function at the portion where the horizontal bar 8 and the cutting blade 7 are attached is an angle adjusting with respect to the horizontal plane and a fine adjusting function of the amount of bite into the cable 11. When the thickness of the flat tail cable 11 changes, the position of the cleaving blade 7 and thus the height of the horizontal bar 8 is changed, but this operation is performed by the horizontal bar 8 adjustment handle 9. Further, the horizontal bar 8 is provided with a plurality of ripping blade 7 installation portions.
