Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a wire stripper for peeling an outer skin of a coated wire material such as an electric wire in which the outer periphery of a core wire is covered.

[Conventional technology]

BACKGROUND ART Conventionally, a hand tool such as a cutter or a nipper has been used to peel off an outer skin of a covered wire material such as an electric wire (hereinafter, an electric wire will be described as an example). In addition, JP-A-62-1890
As shown in Japanese Patent Publication No. 8, a device for peeling the outer skin semi-automatically using air pressure is also provided.

The device disclosed in the above publication is shown in FIG. This device
It has a base 1, a chuck portion 3 for chucking the electric wire 2, a tool rest 4 for peeling the outer skin of the electric wire 2, and a main air cylinder 5 for sliding the tool rest 4 in the direction A in the figure. ing.

In the chuck part 3, a fixed chuck member 6 fixed to the base 1 is arranged to face the fixed chuck member 6, and a movable chuck member 7 slidably provided in the left-right direction (vertical direction in the drawing), An air cylinder 8 for moving the moving chuck member 7 toward and away from the fixed chuck member 6.

The tool rest 4 is slidable in the front-rear direction (left-right direction in the drawing) with respect to the base 1. On the tool rest 4, a fixed tool 9 fixed to the tool rest 4, a movable tool 10 arranged to face the fixed tool 9 and slidably provided in the left and right directions, and the movable tool 10 on the fixed tool 9. Approaching
An air cylinder 11 for separating them is arranged.

A main air cylinder 5 for sliding the tool rest 4 has a main body fixed to the tool rest 4 and a rod thereof.
12 tips are fixed to the base 1.

In addition, the block that supports the fixed tool 9 on the tool rest 4,
A rod 13 is provided that protrudes forward in the horizontal direction.
A positioning member 14 is provided on the rod 13 so as to be slidable in the front-rear direction. At the tip of the positioning member 14, a contact member 15 with which the tip of the electric wire 2 can abut is provided.

In such a device, the outer skin 2a at the tip of the electric wire 2 is
When peeling as shown in the figure, first, the positioning member 14
Is adjusted to an appropriate position in the front-rear direction, and the tip of the electric wire 2 is brought into contact with the contact member 15 of the positioning member 14. In this state, the air cylinder 8 is operated by a foot valve or the like, and the movable chuck member 7 is slid toward the fixed chuck member 6 side to sandwich the electric wire 2 between the chuck members 6 and 7. At the same time, the air cylinder 11 is activated to move the moving blade.
Slide 10 to the fixed blade 9 side. Then, the outer skin 2a of the electric wire 2 is cut by these blades 9 and 10. Next, from this state, the main air cylinder 5 is operated to move the tool rest 4 in the direction A in the figure. This allows the electric wire 2
The outer cover 2a at the tip is peeled off.

[Problems to be solved by the device]

In the conventional device as described above, it is difficult to perform the positioning work because the electric wire 2 has a winding tendency and the contact member 15 cannot be made large in size. Therefore, the operator positions the tip of the electric wire 2 against the abutting member 15 while holding the electric wire 2 immediately behind the portion to be chucked (B portion in FIG. 9). Therefore, the operator's finger may be caught by the chuck members 6 and 7 due to an operation error or the like.

In the conventional device, the clamping force of the electric wire 2 is determined by the pressing force of the air cylinder 8, and if the clamping force is weak, the electric wire 2 may move to the tool rest 4 side when the outer cover is peeled off and may not be peeled off well. Therefore, the electric wire 2 is clamped with a relatively strong force. In such a situation, it is very dangerous when the above-mentioned finger stuffing occurs.

Further, in the conventional device, when the outer diameter of the electric wire 2 changes, the clamping force changes, so the stroke amount of the air cylinder 8 must be adjusted each time the outer diameter changes.

An object of the present invention is to provide a wire stripper that is small in damage even when fingers are stuffed during positioning work of an electric wire, can firmly hold the wire, and does not require an adjusting operation of the holding force. is there.

[Means for Solving the Problems]

A wire stripper according to the present invention is for peeling an outer skin of a wire material whose outer periphery is covered by a wire stripper, and includes a pair of chuck members, a biasing member, a blade, and a peeling driving means. I have it.

The pair of chuck members are opposed to each other and are rotatably arranged around a rotation shaft, and each has a sandwiching portion that can be pressed into contact with the outer skin of the wire. The urging member urges the pair of chuck members in a direction in which the sandwiching portion presses the outer skin body. The blade is disposed so as to be relatively close to and away from the pair of chuck members in the peeling direction of the outer cover body, and is for cutting the outer cover body of the wire material held by the chuck members. The peeling driving means is a means for separating the outer skin from the wire by causing the blade and the chuck member to approach and separate from each other. And, the sandwiching portion of the pair of chuck members is
They have arcuate surfaces that are distant from each other as they move away from the blade and their centers are eccentric to the center of the rotating shaft.

[Action]

In this invention, the wire member from which the outer skin is to be separated is sandwiched by the sandwiching portions of the pair of chuck members. At this time, 1
The pair of chuck members always hold the outer skin of the wire by the biasing member. When the outer skin body is pulled in the peeling direction with the outer skin body of the wire being sandwiched, the sandwiching portions of the pair of chuck members become narrower in space. Therefore,
When the wire rod is pulled toward the tool rest side by the blade when the outer cover is peeled off, the gap between the holding portions is narrowed and the holding force is increased, so that the wire rod is firmly chucked. If the wire rod is moved to the side opposite to the tool rest while it is being held, the distance between the holding parts becomes wider. When the fingers are stuffed, the operator usually pulls the finger on the opposite side of the tool rest, so that the interval between the holding portions is widened and the damage caused by the stuffing can be suppressed.

Further, as described above, the distance between the gripping portions changes depending on the movement of the wire rod, so even if the outer diameter of the wire rod changes, a constant gripping force is automatically obtained, and there is no need to adjust the space between the gripping portions. Becomes

FIG. 7 is a schematic pneumatic circuit diagram of this device.

As is clear from FIG. 7, the air compressor 61
Are connected to a first solenoid valve 24, a second solenoid valve 25, and a limit valve 27 via a distribution valve 26.
The first solenoid valve 24 is connected to the chambers 50a, 50b, 51a, 51b of the air cylinders 50, 51 for moving the blade, and the second solenoid valve 24
The solenoid valve 25 is provided in each chamber 23a, 23b of the main air cylinder 23.
It is connected to the. Further, the limit valve 27 is connected to the air ejection nozzle 54.

Next, the operation will be described with reference to the sequence circuit of FIG. 6 and the pneumatic circuit diagram of FIG.

When the main switch MS is turned on and the foot switch FS is turned off, the first and second solenoid valves 24 and
25 and the limit valve 27 are switched to the F position. Therefore, the blade sliders 44 and 45 connected to the air cylinders 50 and 51 are moved to the most retracted positions. Further, since the rod 59 of the main air cylinder 23 is also in the retracted state, the tool rest 42 is located at the rearmost position. Further, no air is blown out from the air jet nozzle 54.

Such an initial state is shown in FIG. 1A. In this initial state, since the tool rest 42 is moved to the rearmost side as described above, the chuck base plate 30 is moved from each chuck member 31, 32.
The rear end of the push plate 52 abuts on the rods 35 and 36 protruding to the lower surface, and pushes the rods 35 and 36 rearward. Therefore, the chuck members 31 and 32 rotate outwardly against the biasing forces of the torsion springs 39 and 40, and the clamping surfaces 31a and 32 thereof are rotated.
It is in the most open position during a.

In this state, the electric wire 2 is passed through the hole 43a of the guide pipe 43, and the tip end thereof is brought into contact with the contact portion 56a of the positioning rod 56. The positioning rod 56 has a scale 58 printed on the cover 53 according to the size of the outer skin 2a of the electric wire 2 to be peeled off.
The position in the front-back direction is adjusted with reference to.

As described above, in this device, since the tip end portion of the electric wire 2 is guided to the contact portion 56a by the guide pipe 43, the work of setting the electric wire 2 can be performed very easily and accurately. In addition, the operator can set the electric wire 2 without bringing his / her finger close to the chuck portion 21, which is safe.
Further, since the guide pipe 43 can be easily attached to and detached from the tool rest 42, it is possible to easily cope with a change in the diameter of the electric wire 2 by preparing the center holes 43a of various diameters. be able to.

Further, since the scale 58, which serves as a guide for the size for peeling the outer cover 2a, is printed on the upper surface of the cover 53, the peeling size can be set accurately and easily without using a measure or the like.

When the foot switch FS is turned on after the electric wire 2 is set by the above work, the coil CR of the relay is excited and each of the relay contacts CR1 to CR3 is turned on. As a result, the first solenoid valve 24 is operated and switched to the F position and the E position as shown in FIG. Then, the air from the air compressor 61 is supplied into the clamp chambers 50a, 51a of the air cylinders 50, 51 via the distribution valve 26. Therefore, the blade sliders 44 and 45 slide to the center side, respectively, and the blades 46 and 47 fixed to the blade sliders 44 and 45 cut the outer cover 2a of the electric wire 2.

When the relay contact CR1 is turned on, a current is supplied to the relay coil CR via this contact CR1 and a self-holding circuit is formed. Therefore, once relay contact CR
After 1 is turned on, current is continuously supplied to the relay coil CR even if the foot switch FS is turned off.

As described above, in the blade portion 22 of the present device, the electric wire 2 is set in the central portion by the guide pipe 43, and the outer casing 2a of the electric wire 2 is cut by moving the blades 46 and 47 from the left and right sides thereof. Therefore, the outer skin 2a is cut from the left and right sides of the electric wire 2 with substantially the same force. Therefore, the ninth
As in the conventional device shown in the figure, the outer skin 2a can be cut evenly as compared with a device in which the electric wire 2 is supported by the fixed blade 9 and the moving blade 10 is slid from the other side for cutting. . As a result, the core wire in the center of the electric wire 2 is not damaged.

The blade sliders 44 and 45 project, and the blades 46 and 47 allow the electric wire 2
When the outer skin 2a of the blade is cut, the rear end of the blade slider 45 moves to the second position.
The second limit switch LS2 is turned on by pressing the contact of the limit switch LS2. Then, as is apparent from the circuit of FIG. 6, the second solenoid valve 25 is actuated, and the F position shown in FIG. 7 is switched to the E position. This allows
Air from the air compressor 61 is supplied to the rear chamber 23a of the main air cylinder 23 via the distribution valve 26. Therefore, the rod 59 of the main air cylinder 23 projects and slides the tool rest 42 forward through the arm 60 and the slide member 41.

When the slide member 41 slides forward, the push plate 52 on its upper surface moves forward. When the push plate 52 moves forward, the rear ends thereof separate from the rods 35 and 36 of the chuck members 31 and 32. As a result, the chuck members 31 and 32 rotate in the direction in which the electric wire 2 is sandwiched (direction C in FIG. 1A) by the biasing force of the torsion springs 39 and 40.
This state is shown in FIG. 1B.

When the outer skin 2a of the electric wire 2 is peeled off, the tool rest 42 moves forward, so that the electric wire 2 is further pulled forward while being sandwiched between the chuck members 31 and 32. When the electric wire 2 is pulled forward, this force causes the chuck members 31, 32 to rotate in the C direction so as to further clamp the electric wire 2. The chuck members 31 and 32 are shaped so that the distance between the holding surfaces 31a and 32a becomes narrower as they rotate in the C direction, so that the electric wire 2 is more firmly gripped by the wedge effect. Become.

In this device, even when the operator causes finger jamming in the work of setting the electric wire 2, the chuck members 31, 3
The clamping force of 2 itself is weak because it is only due to the torsion springs 39 and 40, and the damage is smaller than that of the conventional device. Further, when the operator pulls his / her finger toward the front when the fingers are jammed, the chuck members 31 and 32 rotate in such a direction that the distance between the sandwiching surfaces 31a and 32a increases, so that the chuck members immediately.
You can pull out your finger from between 31 and 32.

Further, since the distance between the sandwiching surfaces 31a, 32a of the chuck members 31, 32 is arbitrarily changed, adjustment work or the like is unnecessary even when the diameter of the electric wire 2 is changed. Further, the clamping force can always be firmly clamped by the wedge effect as described above.

Further, the mechanism for rotating the chuck members 31, 32 is composed of the torsion springs 39, 40, which is less expensive than the one using the air cylinder as in the conventional device.

In this way, the electric tool 2 is firmly held and the tool rest
When 42 moves forward, the outer cover 2a moves forward as shown in FIG. 1B, and the outer cover 2a at the tip of the outer cover 2a is separated from the electric wire 2.

When the arm 60 slides to the front where the limit valve 27 is provided by the main air cylinder 23, the side surface of the arm 60 contacts the roller contact 27a of the limit valve 27.
As a result, the limit valve 27 is switched from the F position shown in FIG. 7 to the E position. Then the air compressor
The air from 61 is supplied to the air ejection nozzle 54 via the distribution valve 26, and the air is ejected from the air ejection nozzle 54. By this jet of air, the outer cover 2a separated from the electric wire 2 and dropped on the cover 53 is blown off to the side of the apparatus and discharged into the outer cover discharge container (not shown).

When the rod 59 of the main air cylinder 23 protrudes to the most front position, the first limit switch LS
Press the 1 contact. As a result, the first limit switch LS1
Is "open" (off). As is clear from FIG.
When the first limit switch LS1 is turned off, the relay coil CR is no longer excited, so its relay contacts CR1 to CR3
Is turned off. As a result, the first solenoid valve 24 and the second solenoid valve 25 are switched to the F position as shown in FIG. Therefore, the air is supplied to the unclamp chambers 50b and 51b of the air cylinders 50 and 51, and the air is supplied to the front chamber 23b of the main air cylinder 23. As a result, the tool sliders 44 and 45 of the tool rest 42 respectively move outward, and the tool rest 42 itself also slides rearward to the first A position.
The initial state is as shown in the figure.

Further, as the rod 59 of the main air cylinder 23 retracts, the roller contact 27a of the limit valve 27 also turns off, the limit valve 27 is switched from the E position to the F position, and air ejection from the air ejection nozzle 54 is also stopped. To do.

(D) In the above embodiment, the movement of the blade slider 45 is detected by the second limit switch LS2, and the movement of the main air cylinder 23 is detected by the first limit switch LS1. Sensors are not limited to limit switches.

For example, the moving position may be detected by a magnetic sensor, an optical sensor, or the like.

If a magnetic sensor is used and electrical conduction is performed through each member, electrical wiring can be omitted.

(E) When the outer cover 2a of the electric wire 2 is made of a material that is easily scratched, a rubber band may be wound around the outer circumference of each of the chuck members 31 and 32. As a result, the clamping surfaces 31a, 32
The outer skin 2a is not damaged by a.

[Effect of device]

As described above, in the present invention, a pair of chuck members are provided, and the chuck member and the cutter are separated from each other when the wire member is sandwiched by the chuck member, and when the wire member is pulled, the interval between the sandwiching portions becomes narrower.
