Description

  In the present invention, a coated wire is manually set on a pair of wire gripping claws on both sides, the wire tip is brought into contact with the facing wire stopper, and the operator touches the switch operation or the wire contact sensor. In response to the sequence control start signal generated by the detection, the wire is automatically gripped by the gripping claws, and then a pair of blades on both sides are slid along the wire direction according to the strip length, The present invention relates to a semi-automatic wire strip method and apparatus for stripping the strip length and sucking and collecting the stripping coating behind.

  According to Patent Document 1, an electric wire having a frame receiver that rotates in conjunction with an operation shaft and an electric wire frame that is swingably provided on a knob to the frame receiver, and in which a spiral protrusion is formed on the inner surface thereof The blade body that protrudes into the insertion hole and peels and removes is peeled and removed while rotating around the electric wire, and the electric wire comes into contact with the front strip length adjustment stopper, and the thrust is stopped to remove and remove. An electric wire covering peeling tool is disclosed in which an electric wire is set on an electric wire frame by a person's hand and is automatically peeled to a predetermined strip length.

  For such a semi-automatic type, on the premise that the electric wire is automatically conveyed to the gripping position, according to Patent Document 2, it is fixed to the upper surface of the one end side of the base board, and the electric wire fixing portion having a cutter blade is attached to the base board. Insulator peeling device that pulls out while rotating the insulator by holding means for holding the end of the wire on the rotating shaft that can move along the provided guide rail. And a pair of strip blades for forming a cut in the sheath of the covered electric wire, forming a cut in the sheath of the covered electric wire with the strip blade, and retracting the fixed member from the cut position, thereby covering the portion Further, according to Patent Document 4, the strip device for a coated wire that pulls out a wire is transported by a transporter to a wire holder that grips the wire, and not only a strip blade but also a stripping device. Crimping machine or the like of the crimping mechanism for crimping also strips mechanism features facing the wire holder of the terminal is disclosed in portions.

  FIG. 7 shows a semi-automatic electric wire strip device of a type in which a blade as a strip blade is slid in a separation direction along the electric wire direction set with respect to the electric wire gripping claws fixed at these positions and a covering portion is removed. In this manner, the wire 9 held by the operator is set on the wire gripping claw 60, and the contact of the wire tip to the wire stopper 61 driven forward and backward between the wire contact position and the escape position for opening the wire tip is made. In response to the sequence control start signal generated at that time or when detected by the operator's touch or sensor, the electric wire 9 is gripped by automatic operation thereafter (A in the same figure), and a pair of sliding open / close blades 62 slides in conjunction with the wire stopper 61 that has moved to the escape position, and at the strip length specified position, is driven to be closed and slid in accordance with the thickness of the covering 9b to perform cutting (FIG. B). Next, in the process of returning to the original position, the core wire 9a is exposed to a predetermined strip length (Fig. C), and then the coating 9b is recovered behind (D in Fig. D) while the blade 62 is driven to open to the standby position. The kind is also well known.

  However, in this type of semi-automatic wire stripping device according to FIG. 7, in response to the contact of the wire 9 with the wire stopper 61, the blade 62 is slid to cover the strip length in accordance with a predetermined strip length. When the wire is cut according to its thickness, an error occurs in the strip length particularly when the tip portion of the thin wire is bent at the time of contact with the wire stopper, leaving room for improvement. Further, if the separation coating 9b is collected by using a simple structure of air suction without using a sampling pinching mechanism, the blade 62 is peeled off at the original position close to the wire stopper 61. Even if 9b is taken back and returned, a simple pipe suction is likely to cause a recovery error. Further, the pair of blades 62 are usually V-shaped opposed to each other, and the cover 9b is formed with a remaining cut covering portion 9c in a square shape. There is also concern about recovery mistakes caused by adhesion to the core wire 9a.

A pair of blades on both sides that are slidable in the front-rear direction to be separated from and attached to the position-fixed wire gripping claw and are driven to open and close between the standby position and the cutting position are slid to drive the wire coating to a predetermined strip length. Responds to sequence control start signal in the semi-automatic wire strip method in which the stripping coating is sucked back and collected with the wire stopper retracted to the escape position. The step of gripping the wire by driving the wire gripping claw closed, the step of sliding the blade to the terminal cut position slightly forward of the tip of the wire, and the state where the wire stopper is driven back to the escape position The blade is closed and driven at the end cut position to completely cut the end portion of the wire including the core wire to suck and collect the wire residue, to slide the blade to the strip length specified position, and to cover the blade The cutting position is driven to close according to the thickness of the coating to cut the coating, and the blade is slid to the rear position from the terminal cutting position in the cutting state of the coating, the terminal cutting position and the strip length specified position A step of sucking and collecting a release coating having a strip length corresponding to the length between Characterized in that it comprises and.

It is a semi-automatic wire strip device that slides the slide base according to the length, cuts the coating of the wire with the blade, and collects the wire residue behind by suction. In addition to the covering cut position corresponding to the thickness of the covering, it is configured to be closed and driven to a complete cutting position for cutting the electric wire including the core wire, and the sequence control means is responsive to the sequence control start signal. The step of closing the wire gripping claw to the wire gripping position with respect to the wire gripping claw, and the blade slightly to the slide control mechanism than the tip of the wire The blade is driven to close to the full cut position with respect to the open / close control mechanism with the step of sliding the slide base to move to the front end cut position and the backward movement of the wire stopper to the escape position. Then, the blade is moved to the strip length regulation position with respect to the slide control mechanism in a state where the complete cutting is performed and the wire residue is sucked and collected, and the blade is opened to the standby position with respect to the closing control mechanism.

Is adjusted according to the wire diameter so that damage to the electric wire can be avoided.

  An electric wire set plate 13 is attached to the guide rod 12 of the base portion 10a so as to be placed in front of the electric wire gripping claws 15. As shown by a two-dot chain line in FIG. 2, the shape of the front view corresponds to the change of the wire diameter, and the wire center is guided to the wire center line L1 along the V-shaped gripping surface of the wire gripping claw 15; It is formed so as to be gripped at the deepest part of the character shape.

  The base 10a is provided with an air cylinder 13 as a lowering drive actuator so that the elevating base 10b is aligned with the crimping position of the crimping device 40, and a bolt 13a is screwed on a protrusion 13b projecting from the elevating base 10b. The height of the lower end of the bolt restrained by the stopper 10d provided in the base portion 10a is adjusted by the rotation operation of the nut 13c, thereby adjusting the downward stroke from the gripping position shown in the drawing to the crimping position. It is like that.

  As shown in FIG. 1, the slide table 2 has a wire guide plate 21 and V that are slightly shifted in the front-rear direction by the thickness of the blade in order from the front and are opposed to each other with the wire center line L1 as the cut center position. A pair of blades 22 having a letter-shaped tapered blade shape and facing vertically, a light sensor 23 (see FIG. 3) comprising a light emitting part 23a and a light receiving part 23b for detecting the electric wire 9 by blocking the irradiated light, and the tip of the electric wire The covering peeling part 20 provided with the electric wire stopper 24 to contact, and the electric wire waste collection | recovery part 30 which has the suction pump 31 in which the suction pipe 34 protruded and the collection | recovery bag 37 was attached on the back are mounted.

  The pair of blades 22 are respectively attached to a pair of upper and lower sliders 22b that move up and down along guide bars 22a provided on the slide base 2 so as to constitute an opening / closing control mechanism, and a base portion attached to the slide base 2 A step motor 22c that moves forward and backward along the wire center line L1 is attached to 2a, and a pin P22 provided on the slider 22b is formed in a guide groove 22e that is formed in an obliquely symmetrical shape on both the upper and lower sides of the drive head 22d. Is relatively slidable. Therefore, the pair of blades 22 are opened and closed so that the slider 22b approaches the cut position toward the electric wire center line L1 by the advance of the drive head 22d, and is separated from the standby position by the backward drive.

  The electric wire guide plate 21 is attached to the attachment plate 23c, has a shape that allows the electric wire 9 having an assumed diameter to be inserted, and guides the electric wire 9 to the electric wire center line L1 along the V shape when the pair of blades 22 are slid closed.

As shown in FIG. 3, the wire stopper 24 is attached to a cylinder rod of an air cylinder 24a as an advance / retreat driving actuator provided in the base 2a, and is horizontally between the wire contact position and the clearance position where the wire tip is opened. Drives forward and backward in the direction.

As shown in FIG. 3, the mounting plate 23c attached to the upper end of the guide rod 22a is horizontally opposed to the back side of the blade 22 and on both sides of the wire center line L1 at a position close to the front side of the wire stopper 24. Thus, the optical sensor 23 comprised by the light emission part 23a and the light-receiving part 23b is arrange | positioned as an electric wire contact sensor. Thereby, light is irradiated along the front side closest position of the electric wire stopper 24, and the light interruption | blocking by the electric wire 9 in the narrow area | region sufficiently approached with respect to the electric wire stopper 24, for example, about 1 mm can be detected now. As the electric wire contact sensor for generating the sequence control start signal, a light reflection type optical sensor in which the light emitting / receiving portions are juxtaposed on one side or a touch sensor for directly detecting contact on the surface of the electric wire stopper 24 may be adopted. Although it is possible, the light-blocking optical sensor 23 can reliably avoid false detection due to reflections from the surroundings with respect to the former, and is practically at a close position without considering contact sensitivity compared to the latter. The contact state can be detected with a reliable and inexpensive configuration.

  As shown in FIG. 1, a suction pump 31 with a collection bag 37 as a collection unit main body of the wire waste collection unit 30 is attached to a slide base 30a that is slidably guided back and forth on a rail 32 provided on the slide table 2. The tip of the suction pipe 34 is positioned close to the back of the blade 22 when sucked from the standby position shown in the figure by the air cylinder 33 as the forward / backward drive actuator attached to the attachment plate 2b provided on the slide base 2. It is driven forward so that it can occupy.

  As shown in FIG. 4, the wire gripping portion 10 slides to the front of the crimping device 40 by sliding the slide table 42 to the side after the peeling operation is completed, and then the air cylinder 13 is operated to raise and lower the base 10 b. The core wire 9a of the peeled electric wire 9 is set on the terminal 44 set on the cradle 43 by lowering according to the previously set lowering stroke. Subsequently, the crimping claw 46 crimps the terminal 44 by the elevation control mechanism 45 with an actuator, and the bending of the peeling core wire 9a is avoided by matching the height position.

  As shown in FIG. 1, the semi-automatic electric wire strip device of the present invention has a line type with respect to a stepping motor 22c for opening and closing a pair of blades 22 by an input operation at an input unit 51 having a key, a display unit, and the like. Setting data for opening and closing control for sliding the blade 22 to the cover cut position and the complete cut position of the cover thickness corresponding to the above, the cut position of the terminal portion of the electric wire 9 with respect to the slide drive step motor 4 of the slide base 2, and the strip length Setting data holding means 52 for setting and holding slide control setting data for specifying the slide stroke in the front-rear direction according to the specified position and the like, the slide direction thereof, the slide stroke of the step motor 49 for the crimping device 40, and the like; A step for instructing the step operation drive unit to start or return to the step operation. Device control unit 50 programmed computer utilized to configure the sequence control means 53 for outputting a control signal corresponding to the up command signal and the setting data sequentially is included.

  That is, as shown in FIG. 5, the step operation described below is sequentially executed. In response to the sequence control start signal by the contact detection signal of the optical sensor 23 as the wire contact sensor, the associated step command signal is sent to drive the air cylinder 17 to close, thereby moving the gripping claw 15 from the escape position. The electric wire 9 is gripped by moving in the closing direction (step S1). After the timer time of the built-in timer immediately after expecting the operation time, the number of pulses corresponding to the stroke set in advance with respect to the slide drive step motor 4 is sent as a control signal. The slide table 2 is driven to slide so that the blade 22 is moved backward from the operation reference position (see FIG. 6A) to the terminal cut position (see B in the figure) slightly forward of the tip of the electric wire, and the associated step command signal As a result, the electric wire stopper 24 is driven backward to the escape position with respect to the air cylinder 24a (step S2).

  Immediately after the pulse is sent, with the wire stopper 24 retracted to the escape position, forward drive is performed so that the tip of the suction pipe 34 approaches the closest position behind the blade 22 with respect to the air cylinder 33 by the associated step command signal. At the same time, the suction pump 31 performs air suction, and the blade 22 is completely moved to the stepping motor 22c by a control signal belonging to a predetermined number of pulses corresponding to the rotation direction sent immediately after the elapse of the timer time. The cutting position is slidably closed and driven to perform a complete cut (see B in the figure), and the electric wire residue including the core wire 9a is sucked and collected from the suction pipe 34 to the collection bag 37 (step S3).

  After the elapse of the timer time immediately after, the blade 22 is moved to the strip length regulation position with respect to the step motor 4 while the blade 22 is slidably driven to the standby position with respect to the step motor 22c by the pulse control signal. Thus, the slide table 2 is slid and driven by the forward stroke (see C in the same figure) in accordance with the forward control signal having the set number of pulses (step S4). The blade 22 is driven to close to the covering cut position (see FIG. C) according to the thickness of the covering 9b by the pulsed control signal to which the step motor 22c belongs, and the covering 9b is cut (step S5).

  Immediately after the pulse-shaped control signal is sent, the stepping motor 4 moves the blade 22 to a position behind the terminal cut position with respect to the step motor 4 while the blade 22 is closed at the covering cut position. The slide base 2 is slid and driven by the reverse stroke corresponding to the pulse-shaped control signal (see D in the figure), and the length between the terminal cut position and the strip length regulation position is adjusted from the suction pipe 34 interlocked in the suction state. The stripping strip 9b having the corresponding strip length is sucked and collected as an electric wire residue (step S6).

  In response to the subsequent step command signal and control signal for return, the slide base 2 and blade 22 of the coating peeling unit 20 and the slide base 30a of the wire scrap collecting unit 30 are returned to their original positions (step S7). Further, the wire gripping portion 10 is slid sideways to the crimping device 30 by a step motor 49 built in the base board 41 of the crimping device 40 according to the belonging control signal and step command signal, and the wire gripping portion main body 10A according to the immediately following step command signal. Is lowered by the air cylinder 13, the core wire 9a having the strip length is set on the receiving base 43, and the crimping device 40 is started. In response to the subsequent step command signal, the wire gripping portion 10 is returned to the original position for the next peeling process of the wire 9 (step S8).

  The operation of the semi-automatic electric wire strip device of the present invention configured as described above will be described with reference to FIGS. The covered electric wire 9 cut in advance to a predetermined length is manually set on the electric wire set plate 13, and the electric wire guide plate 21 is inserted through the open gripping claws 15, along the electric wire center line L1. When the tip of the electric wire comes into contact with the electric wire stopper 24 in the operating position, the optical sensor 23 detects a portion of the electric wire that is sufficiently close to the electric wire stopper 24, for example, less than 1 mm. The electric wire 9 is automatically gripped (see FIG. 6A), and thereafter the peeling operation automatically proceeds.

  By the step S2, the slide table 2 is slightly retracted, so that the pair of blades 22 are retracted to the terminal portion cutting position, for example, about 1 mm ahead of the tip of the gripped electric wire 9, and the wire stopper 24 is in the escape position. Retreat to. In step S3, with the tip of the suction pipe 34 approaching the closest position behind the blade 22 and the air suction is started, the blade 22 is slid to the complete cut position and the end portion of the electric wire 9 is completely cut. Then, the wire residue is collected in the collection bag 37 via the suction pipe 34 (see FIG. 5B).

  In step S4, the blade 22 is slid open to the standby position, and is advanced from the terminal cut position of the terminal portion by about 5 mm, for example, according to the strip length to advance to the strip length specified position. In step S5, the blade 22 22 is closed and driven to a coating cutting position (see C in the figure) corresponding to the thickness of the coating 9b, and the coating 9b is cut.

  In step S6, when the blade 22 is closed at the covering cut position, the suction is performed backward in conjunction with the suction state by retreating to the rear position, for example, about several millimeters from the terminal cut position (see D in the figure). The strip coating 9b having a strip length of, for example, about 5 mm is sucked and collected from the pipe 34 as an electric wire residue, and the portions of the coating peeling unit 20 and the electric wire collecting unit 30 are returned to the initial state in step S7.

  Finally, in step S8, the wire gripping portion 10 is slid to the side crimping device 30, and then the wire gripping portion main body 10A is lowered, and the core wire 9a from which the covering 9b is peeled is set at the crimping position and is connected to the terminal 44. In this case, the crimped portion remains straight along the straight direction of the wire 9 without bending due to the exact height position, and then the wire gripping portion 10 and the wire gripping portion main body 10A are in their original positions. Return to.

  In the above-described embodiment, the sequence control start signal has been described on the assumption that it is automatically generated by the wire contact sensor. However, as another embodiment of this semi-automatic device, the operator When the electric wire 9 is set on the electric wire set plate 13, the electric wire guide plate 21 is inserted through the gripping claws 15 in the open state, and the contact of the electric wire tip with the electric wire stopper 24 is detected, a foot switch or a push button A sequence control start signal can be generated by a switch operation by an operator such as a switch so that the sequence operation after gripping the wire is automatically performed.

  Further, the slide control mechanism of the slide base 2 of the coating peeling unit 20, the opening / closing control mechanism of the pair of blades 22, and the slide mechanism of the wire gripping unit 10 to the crimping device 40 can be controlled in position in response to a control signal. Although the control drive unit is configured with each motor attached, the sequence control can be sequentially executed by performing the control drive in response to the set target position detection feedback signal by the servo motor.
