An air cylinder 27 for cutting is fixed to an upper portion of the plate 26. As shown in cross section in FIG. 4, the rod 28 of the air cylinder 27 extends downward through a hole 26a formed in the plate 26. As shown in FIG. 3 which is a cross-sectional plan view of FIG. 1, the slider base member 25 has a concave portion
b. Guide plates 30 and 31 are fixed to the left and right sides of the side surface 25a of the slider base member 25. As is clear from FIGS. 1 and 4, the guide plates 30 and 31 are provided to extend in a vertical direction at a predetermined length. Thus, the guide groove 32 (see FIG. 3) is formed by the concave portion 25b of the slider base member 25 and the guide plates 30 and 31. In addition,
At the front of the air cylinder 27, a magnetic sensor 24 for detecting that the rod 28 of the air cylinder 27 has protruded and moved to the lowermost end is fixed.

As shown in FIG. 4, the cutting air cylinder 2
A slide plate 33 is fixed to the lower end of the rod 28 by screws. This slide plate 33
As is clear from FIG. 3, a guide flange 33a is provided on the rear side. The guide flange 33a is slidably engaged with the guide groove 32. A U-shaped U-shaped block member 34 is provided on the lower surface of the slide plate 33.
Are fixed by screws. Through holes 34a and 34b are formed on both left and right sides of the U-shaped block member 34. A female screw portion 34c is formed at the bottom center. The through holes 34a, 34 of the U-shaped block member 34
Pins 35 and 36 are inserted in b. Pin 35, 3
The upper end of 6 is fixed to the lower surface of the slide plate 33 by screws. An upper blade attachment member 37 is disposed below the U-shaped block member 34. Through holes 37a and 37b are formed on both sides of the upper blade mounting member 37, and the pins 35 and 36 penetrate therethrough. An upper blade 38 is fixed to the front surface of the upper blade mounting member 37. A core wire cutter mounting member 39 is fixed to the lower ends of the pins 35 and 36 by screws.

A core wire cutter 42 is fixed to the front surface of the mounting portion 41. A fixing screw 49 is mounted on the right side of the frame portion 40, and the position of the mounting portion 41 with respect to the frame portion 40 is fixed by the fixing screw 49 . A spring 43 is disposed between the upper part of the core wire cutter mounting member 39 and the lower part of the upper blade mounting member 37. This spring 43
Thereby, the upper blade attachment member 37 and the core wire cutter attachment member 39 are urged in directions away from each other.

An adjusting bolt 45 is screwed into the female screw portion 34c of the U-shaped block member 34. The head 45 a of the adjustment bolt 45 is housed in a space 46 formed by the U-shaped block member 34. The tip of the screw portion 45b is in contact with the upper surface of the upper blade attachment member 37. Therefore, by rotating the adjustment bolt 45, the vertical position of the upper blade attachment member 37 can be adjusted.
That is, it is possible to adjust the distance between the upper blade 38 and a lower blade described later when the upper blade 38 and the lower blade approach each other by the adjustment bolt 45. The head 45a of the adjustment bolt 45 has a plurality of holes 45c used for rotating the adjustment bolt 45.

As is apparent from FIG. 2, a lower block member 50 is fixed to the slider base member 25 below the cutting portion 3. A lower blade 51 is attached to the lower block member 50 so as to face the upper blade 38. Also, the lower blade 51 on the upper surface of the lower block member 50.
Behind, a cutter receiving plate 52 is fixed so as to face the core wire cutter 42. The cutter receiving plate 52 is a member with which the lower end of the core wire cutter 42 contacts when cutting the core wire, and is formed of a soft material such as an aluminum material or a copper material.

Next, the sequence circuit of the apparatus of this embodiment will be described with reference to FIG. The main switch MS is provided on the front surface of the case 5 of the base unit 1. This main switch M
A fuse F is connected in series with S, and a pilot lamp PL is connected in parallel. A foot switch FS is connected to this device, and a relay coil CR is connected to the foot switch FS in series. Further, in parallel with the foot switch FS, relay contacts CR1, CR2, CR3 operated by a relay coil CR are connected.
The relay contact CR1 and the first limit switch LS1 are connected in series, the relay contact CR2 and the first solenoid valve SOL1 are connected in series, and the relay contact CR3
The second limit switch LS2 and the second solenoid valve S
OL2 are connected in series.

The first limit switch LS1 is "closed" in a normal state, and is provided at an end portion (in FIG. 1 at the back in the direction perpendicular to the paper) of the case 5. When the rod of the main air cylinder 6 protrudes, the connecting member 8 connects to the first limit switch LS1.
To open. The second limit switch LS2 is “open” in a normal state, and is controlled by a signal from a magnetic sensor 24 attached to the front surface of the cutting air cylinder 27. That is, the second limit switch LS2 is "closed" with the rod 28 of the cutting air cylinder 27 most protruding.

FIG. 8 is a schematic pneumatic circuit diagram of the present apparatus. In the figure, an air compressor 60 includes a first solenoid valve SOL1 and a second solenoid valve SO via a distribution valve 61.
L2 and the limit valve 62. First
The solenoid valve SOL1 is connected to each chamber 11a, 11b of the chuck air cylinder 11 for moving the upper chuck 14, and each chamber 27a, 27b of the cutting air cylinder. The second solenoid valve SOL2 is connected to each of the chambers 6a and 6b of the main air cylinder 6. The limit valve 62 is connected to the air ejection nozzle 63.

Next, the operation will be described. When the main switch MS is turned on and the foot switch FS is turned off, the first and second solenoid valves SOL1,
SOL2 and the limit valve 62 are respectively F
The position has been switched. Therefore, the upper chuck 14 connected to the air cylinder 11 for chuck and the upper blade 38 connected to the air cylinder 27 for cutting are respectively moved to the highest positions. Further, since the rod of the main air cylinder 6 is also in a retracted state, the cutting portion 3 is located at the forefront, that is, at a position close to the chuck portion 2. Further, no air is jetted from the air jet nozzle 63. In this state, the screw 23 of the lower block member 50 abuts on the lower chuck 18 to restrict its rotation. For this reason, the lower chuck 18 is in the posture shown by the solid line in FIG.

When exfoliating the endothelial body to expose the core wire, the outer skin is first peeled off by the outer skin stripping device. Then, a plurality of cables exposed from the outer cover are arranged in a horizontal direction, and a cable insertion guide 2 is provided.
Each cable is inserted into one guide groove 21a. This state is shown in FIG. At this time, the plurality of cables are arranged so that the tips thereof are located further forward than the core wire cutter 42.

When the foot switch FS is turned on after the cable is set by the above operation, the relay coil CR shown in FIG.
CR3 is turned on. As a result, the first solenoid valve SOL1 is operated to switch from the position F to the position E shown in FIG. Then, air from the air compressor 60 is supplied to each of the air cylinders 11 and 12 via the distribution valve 61.
7 are supplied to the chambers 11b and 27b. Accordingly, the rod 12 of the chuck air cylinder 11 contracts, and the L-shaped member 13 and the upper chuck 14 descend. Thereby, a plurality of cables are gripped between the upper chuck 14 and the lower chuck 18. The lowermost position of the L-shaped member 13 is regulated by the regulating nut 16. Therefore, the restricting nut 1 is adjusted to the outer diameter of the inner sheath of the cable.
By adjusting 6 in advance, the gripping force of the chuck can be adjusted.

The rod 2 of the cutting air cylinder 27
By the lowering of 8, the upper blade mounting member 37 is lowered via the slide plate 33, the U-shaped block member 34 and the adjustment bolt 45. This also lowers the upper blade 38,
The inner blade of each cable is cut by the upper blade 38 and the lower blade 51. FIG. 9 shows a state where the lower blade 38 is lowered, and FIG. 10 shows a state where the cable is chucked and the endothelial body is cut.

When the relay contact CR1 is turned on, a current is supplied to the relay coil CR via the contact CR1 to form a self-holding circuit. Therefore, once the relay contact CR1 is turned on, current is continuously supplied to the relay coil CR even if the foot switch FS is turned off. Further, when the slide plate 33 is lowered, the core wire cutter mounting member 39 is also lowered via the pins 35 and 36. Therefore, the core wire cutter 42
Is also lowered at the same time as the lower blade 38, and in a state where the rod 28 of the cutting air cylinder 27 projects most, the core wire cutter 42
Is in contact with the cutter receiving plate 52. Therefore, as shown in FIG. 10, both the endothelial body and the core wire are cut by the core wire cutter 42 at the distal end of each cable.

When the rod 28 of the cutting air cylinder 27 projects, the magnetic sensor 24 detects that the rod 28 protrudes, and the second limit switch LS2 is turned on. Then, the second solenoid valve SOL2 operates to switch from the position F to the position E shown in FIG. As a result, the air from the air compressor 60 is supplied to the main air cylinder 6 via the distribution valve 61, and the rod 3 projects from the chuck 2 via the connecting member 8 and the slide member 9. Slide away.

As the entire cutting section 3 slides,
The upper blade 38 and the lower blade 51 also move in the same direction. For this reason,
Each cable is pulled to the right in FIG. Further, since the screw 23 is separated from the lower chuck 18, the lower chuck 18 is rotated clockwise by the torsion spring 20,
The grip 18a presses against the cable. When the cable is pulled in the same direction, the lower chuck 18 further rotates clockwise (FIG. 11). When the lower chuck 18 rotates in this direction, the posture shown by the solid line in FIG. 5 approaches the posture shown by the alternate long and short dash line, and the distance between the lower chuck 18 and the upper chuck 14 is reduced. Therefore, each cable is more firmly gripped by the wedge effect of the upper chuck 14 and the lower chuck 18.

When the cut portion 3 moves in the peeling direction while the cable is firmly gripped in this way, only the endothelium moves in the same direction as shown in FIG. 11, and the core wire at the tip of the cable is exposed. . When the cutting section 3 is moved to a predetermined position by the main air cylinder 6, the limit valve 6
The connecting member 8 contacts the second roller contact 62a. Thereby, the limit valve 62 is switched from the F position to the E position in FIG. Then, the air from the air compressor 60 is supplied to the air ejection nozzle 63 via the distribution valve 61, and the air is ejected from the air ejection nozzle 63. By this air ejection, the endothelial body on the cutter receiving plate 52 is peeled off from the cable and blown to the side of the apparatus.

When the rod of the main air cylinder 6 projects to the frontmost position, the front end face of the connecting member 8 pushes the contact point of the first limit switch LS1. As a result, the first limit switch LS1 is turned "open" (off). As is clear from FIG. 6, when the first limit switch LS1 is turned off, the relay coil CR is not excited, and the relay contacts CR1 to CR3 are turned off. As a result, the first solenoid valve SOL1 and the second solenoid valve SOL2 are switched to the F position as shown in FIG.
Accordingly, each chamber 11a, 2 of the air cylinder 11, 27
Air is supplied to the chamber 7b of the main air cylinder 6 while air is supplied to the main air cylinder 7a. As a result, the loaders of the cylinders 11, 27, and 6 are retracted, the upper chuck 14 and the upper blade 38 are raised, and the cutting section 3 is also moved to the chuck section 2 to be in an initial state.

Further, when the rod of the main air cylinder 6 is retracted, the roller contact 62a of the limit valve 62 is also turned off. Therefore, the limit valve 62 is switched from the E position to the F position, and the air ejection nozzle 63
Air blowing from the air also stops. Next, adjustment of the cutting amount of the endothelial body will be described.

When the diameter or thickness of the endothelial body changes, the cutting amount is changed by adjusting the upper and lower positions of the upper blade. In this case, a tool or the like is inserted into the hole 45c of the head 45a of the adjustment bolt 45, and thereby the adjustment bolt 45 is rotated. When the female screw portion 45b is rotated so as to protrude downward, the upper blade mounting member 37 is lowered against the urging force of the spring 43, whereby the initial position of the upper blade 38 moves downward.
Therefore, even when the outer diameter of the endothelium is small or the endothelium is thick, the interval between the upper blade 38 and the lower blade 51 is narrowed, and only the endothelium can be reliably cut. By rotating the adjustment bolt 45 in the opposite direction, the tip of the female screw portion 45b is raised, and the upper blade mounting member 37 is raised by the urging force of the spring 43. For this reason, the upper blade 3
8 also rises, and the interval between the upper blade 38 and the lower blade 51 increases at the time of cutting (the position where the upper blade 38 is lowered most). For this reason, even when the outer diameter of the endothelium is large or the endothelium is thin, only the endothelium can be reliably cut.

In this apparatus, when the fixing screw 49 of the core wire cutter mounting member 39 is loosened and the mounting portion 41 is moved in the front-rear direction with respect to the frame portion 40, the distance L in FIG. For this reason, the exposed length of the core wire when the endothelial body is peeled can be arbitrarily changed. Also, by adjusting the vertical position of the regulating nut 16 according to the diameter of the endothelial body and regulating the descending position of the upper chuck 14, the endothelial body can always be chucked with an appropriate gripping force on endothelial bodies having different diameters. Can be. In this device,
Since the lower chuck 18 rotates and the distance between the lower chuck 18 and the upper chuck 14 is automatically adjusted, it is not necessary to strictly control the vertical position of the restricting nut 16.

As described above, in the present embodiment, a plurality of cables are chucked in the chuck portion 2 and the inner sheath of each cable is simultaneously cut and peeled by the upper blade 38 and the lower blade 51. Therefore, a hand stripper or the like is used for each cable. This eliminates the need to perform the core wire stripping operation, and the operation can be performed easily and in a short time. In addition, since the core wire cutter 42 is provided, the lengths of the tips of a plurality of cables can be made uniform at the same time as the endothelial body is separated. Further, since the cutting position of the core wire cutter can be adjusted, the stripped length of the core wire can be arbitrarily changed.

Further, in the chuck portion 2 of the present embodiment, the lower chuck 18 is rotated, and the distance between the grip portion 14a of the upper chuck 14 and the grip portion 18a of the lower chuck 18 is arbitrarily changed. There is no need to strictly adjust the interval between the two. In addition, the gripping force of the two chucks 1
It is always firmly gripped by the wedge effect of 4,18. [Other Embodiments] (a) In the above embodiment, the chuck part 2 is fixed to the base part 1 and the cutting part 3 is slidable in the front-back direction. Alternatively, the chuck 2 may be slid in the front-rear direction. (B) In the above embodiment, the second limit switch LS2 is operated by the movement of the rod of the cutting cylinder.
May be operated to operate the second limit switch LS2. (C) In the above embodiment, the lowering position of the L-shaped member 13 and the upper chuck 14 is regulated by the screw member 15 and the regulating nut 16 screwed to the screw member 15, but the regulating nut 16 is omitted. The L-shaped member 13 may be directly applied to the screw portion of the screw member 15 for regulation. In this case, the adjustment of the lowered position is performed by screwing or unscrewing the screw member 15 with respect to the chuck base member 10.
