Japanese Utility Model Publication No. 04-86667

  In the above-described linear member feeding device, the mounting plate is required to have a strength for supporting the linear member, and needs to be formed of metal or a high-strength synthetic resin, resulting in an increase in the weight of the mounting plate. Increasing the weight of the mounting plate uses a large motor to rotate the mounting plate, increasing the weight of the entire linear member feeding device.

  This invention solves the above-mentioned subject, and it aims at providing the linear member feeding apparatus reduced in weight.

  According to the first aspect of the present invention, the main body, the driving device disposed in the main body, the rotating shaft extending in the vertical direction and rotated by the driving device, and the upper portion of the rotating shaft are disposed. A support member and a linear member that is formed in a long shape, is fixed to the support portion on one end side, and extends in an arc shape that bulges outward downward, and is wound in a coil shape toward the radially outer side of the rotating shaft. A linear member feeding device having a plurality of holding hooks to be urged, wherein the holding hook has a holding part formed such that the other end side is bent outward and the linear member can be held.

  According to this, since the mounting board which mounts a linear member becomes unnecessary, it becomes possible to reduce the weight of the part. Accordingly, it is not necessary to use a large motor for rotating the mounting plate, and the entire linear member feeding device can be reduced in weight.

  And a support frame disposed upward from the main body portion, and a detection means disposed above the support portion via the support frame and detecting the degree of tension of the linear member. Is configured to transmit a signal for accelerating, decelerating, intermittently driving or stopping the driving device to the driving device according to the detected degree of tension of the linear member.

  When feeding the linear member wound in a coil shape, if the position of the starting point of the linear member moves in the radial direction, the position of the starting point of the linear member feeding per unit time is moved even at the same rotation angle. Since the distance is changed, a gap is generated between the feeding speed of the linear member and the rotational speed of the holding portion that holds the linear member, which causes kinking and entanglement of the linear member.

  Depending on the degree of tension of the linear member detected by the detecting means, a signal for accelerating, decelerating, intermittently driving or stopping is transmitted from the detecting means to the driving device, thereby holding the linear member feeding speed and the linear member. The gap with the rotation speed of the holding portion can be eliminated, and the linear member can be fed out satisfactorily.

  A support frame formed at least partially from an elastic member and disposed upward from the main body; and a guide unit disposed above the support via the support frame and guiding the linear member. When the linear member is in a stretched state, the support frame bends to release the stretch of the linear member, and then the linear member is pulled out by the restoring force of the support frame, A gap between the feeding speed of the member and the rotation speed of the holding portion that holds the linear member can be eliminated.

  Further, the support portion is formed so as to be rotatable with respect to the rotation shaft, and when the feeding speed of the linear member and the rotation speed of the rotation shaft are equal and the feeding of the linear member is balanced, When the rotation speed of the rotating shaft is slower and the linear member is in a stretched state, even if the support portion rotates faster than the rotating shaft, the feeding speed of the linear member and the linear member The gap with the rotational speed of the holding part that holds the can be eliminated.

  A variable resistor connected to the driving device; and a detection conversion means for detecting the movement of the holding collar in the radial direction of the rotating shaft and converting the movement into the axial direction of the rotating shaft. Has a resistor and a contact that is movable with respect to the resistor, and the detecting conversion means is provided with an engaging portion that engages with the contact, and the engaging portion and the contact engage with each other to detect It is also possible to adjust the drive current to the drive device by moving the conversion means.

  According to this, the gap between the feeding speed of the linear member and the rotation speed of the holding part that holds the linear member is adjusted by adjusting the driving current of the driving device by moving the engaging part between the engaging part and the contact point. Can be eliminated.

  A first limit switch 82 having a lever 82a and a plunger 82b is disposed on the right side of the horizontal column 72 in the vicinity of the guide portion 80. The linear member W is formed so that the connection is switched by pressing the plunger 82b via the lever 82a.

  The detection unit 90 includes a detection unit 91 and a second limit switch 92.

  The detection unit 91 includes a rotation shaft portion 91a, a pressing lever portion 91b, and a detection lever portion 91c.

  The rotation shaft portion 91 a is formed in a rectangular flat plate shape and is disposed at the lower end portion of the support plate 93 extending downward from the right end portion of the horizontal column 72, and is rotatable with respect to the support plate 93 about the front-rear direction.

  As shown in FIG. 5, the rotation speed adjustment circuit of the drive device 30 is connected to the second limit switch 92 via the motor driver 32, and is driven by the movement of the plunger 92 b of the second limit switch 92. The signal transmitted to the device 30 can be switched to a predetermined rotation speed (hereinafter referred to as high speed rotation) or a rotation speed slower than the predetermined rotation speed (hereinafter referred to as low speed rotation).

  The driving device 30 is connected to the power source 33 via the motor driver 32 and the first limit switch 82, and the signal circuit that transmits to the driving device 30 by the movement of the plunger 82b of the first limit switch 82 is connected or disconnected. It is configured to be switchable to a state.

  The usage mode and function of the linear member feeding device 10 having the above-described configuration will be described.

  The linear member W wound in a coil shape is put in from the upper side (the support portion 50 side) and is held by the holding portion 60a of the holding collar 60. The linear member W is pulled out from the inner peripheral side and is inserted in the order of the annular portion 91d of the detection lever portion 91c and the insertion hole 72a of the horizontal column 72. Then, the linear member W is passed between the guide rollers 80a and 80b and meshed with a pulling roller of an apparatus (not shown) in a subsequent process. At this time, the linear member W is in a state of pressing the plunger 82b via the lever 82a.

  When the pulling roller of the device in the post-process is driven to pull the linear member W, the driving device 30 is driven, and each holding collar 60 is rotated via the rotating shaft 40, the wire wound in a coil shape The W-shaped member W is unwound from the inner peripheral side and fed out. That is, the pulling speed of the linear member W of the pulling roller of the apparatus in the subsequent process becomes the feeding speed of the linear member W.

  Each holding hook 60 is formed of an elastic member, and the holding part 60a moves outward, and the linear member W is fed out, so that the weight applied to each holding hook 60 gradually decreases. The position of the starting point of feeding of the shaped member W moves in the radial direction.

  If the position of the starting point of the linear member W moves in the radial direction, the moving distance of the position of the starting point of the linear member W per unit time changes even at the same rotation angle. As a result, a gap is generated in the rotational speed of the holding portion 60a that holds the linear member W, which causes the linear member W to be kinked or entangled.

  As shown by the two-dot chain line in FIG. 6, when the feeding speed of the linear member W is equal to the rotational speed of the holding portion 60a that holds the linear member W and the feeding of the linear member W is balanced. The annular portion 91d of the lever portion 91c is on the right side in contact with the linear member W, and the pressing lever portion 91b is on the right side, away from the lever 92a of the second limit switch 92, and the driving device 30 rotates at high speed. Set as follows.

  The rotation speed of the holding portion 60a that holds the linear member W is higher than the feeding speed of the linear member W, and the feeding of the linear member W increases and becomes loose, as shown by the solid line in parentheses in FIG. When the annular portion 91d of the detection lever portion 91c is released from contact with the linear member W, the detection lever portion 91c and the pressing lever portion 91b rotate clockwise. Then, the pressing lever portion 91b presses the lever 92a and the plunger 92b of the second limit switch 92 to switch the driving device 30 so as to rotate at a low speed, thereby reducing the feeding of the linear member W. The feeding speed and the rotation speed of the holding portion 60a that holds the linear member W return to a balanced state.

  Further, when the linear member W is extended, the linear member W presses the plunger 82b via the lever 82a of the first limit switch 82, and the drive device 30 and the power source 33 are connected to each other. When all of them are extended, as the operation stop means of the drive device 30, the pressing of the linear member W to the plunger 82 b is released, and the connection between the drive device 30 and the power source 33 is disconnected, and the rotation of the drive device 30 is performed. Stops.

  Further, since the holding collar 60 is formed of a bar member having elasticity, the linear member W at the starting point of the linear member W is held together with the linear member W positioned above the linear member W. Even if it is sandwiched between the portions 60a, the inner circumferential side of the linear member W wound in a coil shape is held inclined with respect to the vertical direction to reduce the installation pressure, and it becomes easier to come out by bending. Only the holding part 60a rotates, and it is possible to prevent the occurrence of problems in the post-process apparatus due to the kinking of the linear member W or the like.

  In the linear member feeding device 10 configured as described above, the main body 20, the driving device 30 disposed in the main body 20, the rotating shaft 40 that extends along the vertical direction and is rotated by the driving device 30, and rotation A support portion 50 disposed on the upper portion of the shaft 40, and a linear member that is formed in an elongated shape, is fixed to the support portion 50 on one end side, and extends in an arc shape that swells outward downward, and is wound in a coil shape A linear member feeding device having a plurality of holding hook portions 60 that urge W toward the radially outer side of the rotary shaft 40, wherein the holding hook portion 60 is bent at the other end side to the outer side. The holding portion 60a is formed so as to be able to hold W.

  According to this, since the mounting board which mounts the linear member W becomes unnecessary, it becomes possible to reduce the weight of the part. Accordingly, it is not necessary to use a large drive device 30 for rotating the mounting plate, and the entire linear member feeding device 10 can be reduced in weight.

  Also, a support frame 70 disposed upward from the main body 20, a detection unit 90 disposed above the support 50 via the support frame 70 and detecting the degree of tension of the linear member W, The lever 92a and the plunger 92b of the detecting means 90 are in a state in which the feeding speed of the linear member W is equal to the rotational speed of the holding portion 60a that holds the linear member W, and the feeding of the linear member W is balanced. Alternatively, a signal that causes the drive device 30 to rotate at a high speed or a low speed is transmitted to the drive device 30 when the linear member W is loosened due to a lot of feeding.

  When feeding the linear member W wound in a coil shape, if the position of the starting point of the linear member W moves in the radial direction, the starting point of the feeding of the linear member W per unit time is changed even at the same rotation angle. Since the moving distance of the position changes, a gap is generated between the feeding speed of the linear member W and the rotational speed of the holding portion 60a that holds the linear member W, which causes the linear member W to be kinked or entangled. It was.

  Therefore, the feeding speed of the linear member W is increased by rotating the driving device 30 at a high speed or a low speed according to a position signal in which the feeding of the linear member W detected by the detecting means 90 is balanced or loosened. The gap with the rotational speed of the holding part 60a holding the linear member W can be eliminated, and the linear member W can be fed out satisfactorily.

  The linear member feeding device 10 of the present invention is not limited to the above configuration. That is, various design changes can be made without departing from the gist of the present invention.

The linear member W is pulled out from the inner peripheral side, and is inserted through the ring portion 83a of the ring arm portion 83 and the insertion hole 72a of the horizontal column 72 in this order. Then, the linear member W is passed between the guide rollers 80a and 80b and meshed with a pulling roller of an apparatus (not shown) in a subsequent process.

  When the rotation speed of the holding portion 60a that holds the linear member W is lower than the feeding speed of the linear member W and the linear member W is stretched, the support frame 70A moves to the right as shown by the solid line in FIG. Bend in the direction to release the tension of the linear member W.

  Thereafter, the linear member W is pulled out by the return force of the support frame 70A in the left direction, and the position of the starting point of the linear member W being fed is the rotational direction of the rotary shaft 41 in the plan view (counterclockwise). ) In the opposite direction (clockwise), and returns to a state in which the feeding of the linear member W is balanced, as shown by a two-dot chain line in FIG.

  Even with such a configuration, the gap between the feeding speed of the linear member W and the rotational speed of the holding portion 60a that holds the linear member W can be eliminated.

  A third embodiment of the present invention will be described. In the linear member feeding device 10 </ b> B, the support portion 51 is formed to be rotatable with respect to the rotation shaft 41.

  As shown in FIGS. 8 and 9, the rotary shaft 41 has a small diameter portion 41a in which the outer peripheral diameter of the upper end portion is smaller than the lower portion, and the screw hole extends downward from the upper end surface of the small diameter portion 41a. 41b is formed.

  The stay 53 has a through hole 53a penetrating along the vertical direction on one end side when viewed from the front, and a cylindrical roller 54 is attached to the lower side of the other end side so as to be rotatable about the vertical direction. Yes.

  The stay 53 is fixed to the small-diameter portion 41 a by connecting the screw hole 41 b of the small-diameter portion 41 a and the through-hole 53 a of the stay 53 and fastening with the bolt 56. A slight load in a state where the roller 54 is positioned and meshed between any two teeth 52b, the spur gear 52 is urged toward the rotating shaft 41 by the roller 54, and the feed of the linear member W is balanced. Then, the spur gear 52 and the rotating shaft 41 can be maintained in a state of rotating integrally.

  The usage mode and function of the linear member feeding device 10B having the above-described configuration will be described. The rotation shaft 41 is assumed to rotate counterclockwise as indicated by an arrow in FIG.

  The linear member W wound in a coil shape is held by the holding portion 60 a of the holding collar portion 60. The linear member W is pulled out from the inner peripheral side, and is inserted through the ring portion 83a of the ring arm portion 83 and the insertion hole 72a of the horizontal column 72 in this order. Then, the linear member W is passed between the guide rollers 80a and 80b and meshed with a pulling roller of an apparatus (not shown) in a subsequent process.

  In a state where the feeding speed of the linear member W and the rotational speed of the rotary shaft 41 are equal and the feeding of the linear member W is balanced, the roller 54 is positioned between any two teeth 52b and maintains a meshed state. Then, it rotates integrally with the rotating shaft 41.

  Further, when the rotational speed of the rotating shaft 41 becomes slower and the linear member W is in a stretched state, the roller 54 escapes from between any two teeth 52b to release the meshed state, and FIG. , The support portion 51 rotates faster (precedingly) than the rotating shaft 41 rotating in the counterclockwise direction.

  Even with such a configuration, the gap between the feeding speed of the linear member W and the rotational speed of the holding portion 60a that holds the linear member W can be eliminated.

  A fourth embodiment of the present invention will be described. The linear member feeding device 10 </ b> C detects the movement of the variable resistor 100 connected to the driving device 30 and the holding rod 60 in the radial direction of the rotating shaft 40 and detects the movement of the rotating shaft 40 in the axial direction (vertical direction). Detection conversion means 110 for converting into movement.

  The variable resistor 100 includes a resistor 100a and a movable contact 100b that can slide along the vertical direction with respect to the resistor 100a.

  The detection conversion means 110 includes a support portion 50, a spring receiver 111, a compression coil spring 112, and a link bar 113.

  The spring receiver 111 is formed in a stepped disk shape having a large-diameter portion 111a and a small-diameter portion 111b. In a plan view, a shaft hole 111c penetrating in the vertical direction is formed in the center, and the bearing 114 is fitted into the shaft hole 111c. In addition, it is slidable along the vertical direction with respect to the rotating shaft 40. An attachment member 111d extending downward from the lower end portion on the small diameter portion 111b side of the spring receiver 111 is disposed, and an engagement portion 111e that engages the contact 100b is disposed on the lower end portion of the attachment member 111d. Has been.

  By engaging the engaging portion 111e and the contact point 100b and moving the detection conversion means 110, the drive current to the drive device 30 can be adjusted.

  As shown in FIG. 11, the rotation speed adjustment circuit of the drive device 30 is connected to the variable resistor 100 via the motor driver 32, and is based on the vertical movement of the contact 100 b of the variable resistor 100. The drive device 30 is configured to gradually shift from high-speed rotation to low-speed rotation by changing the resistance value.

  The usage mode and function of the linear member feeding device 10C having the above-described configuration will be described.

  The linear member W wound in a coil shape is held by the holding portion 60 a of the holding collar portion 60. The linear member W is pulled out from the inner peripheral side, and is inserted through the ring portion 83a of the ring arm portion 83 and the insertion hole 72a of the horizontal column 72 in this order. Then, the linear member W is passed between the guide rollers 80a and 80b and meshed with a pulling roller of an apparatus (not shown) in a subsequent process.

  When the linear member W wound in a coil shape is held by the holding part 60a of the holding hook part 60, the holding hook part 60 moves toward the rotary shaft 40 as shown by the solid line in parentheses in FIGS. Make it flexible. Thereby, the spring receiver 111 connected to the link bar 113 compresses the compression coil spring 112 and is positioned above the position at the free height of the compression coil spring 112. Accordingly, the contact 100b of the variable resistor 100 is located on the upper side of the variable resistor 100.

  When the linear member W wound in a coil shape is fed out, the holding hook 60 urges the linear member W toward the radially outer side of the rotating shaft 40, so that the linear member W is fed out. The position of the starting point moves in the radial direction. At this time, the holding hook 60 tries to spread outward, but is connected to the large-diameter portion 111a of the spring receiver 111 by the link bar 113 and the restoring force of the compression coil spring 112 acts. Is controlled to move radially outward. As a result, as indicated by a two-dot chain line in parentheses in FIG. 10, the movement of the holding collar 60 outward in the radial direction of the rotating shaft 40 is converted into the downward movement of the spring receiver 111.

  Therefore, the drive current of the drive device 30 can be adjusted by moving the engagement portion between the engagement portion 111e extending from the spring receiver 111 and the contact point 100b in the vertical direction.

  Even with such a configuration, the gap between the feeding speed of the linear member W and the rotation speed of the holding portion 60a that holds the linear member W can be eliminated.

  Further, as a modification of the linear member feeding device 10, it is possible to set the driving device 30 to be intermittently driven (stopped) by switching by movement of the plunger 92 b of the second limit switch 92.

  As shown in FIG. 12, the rotation speed adjustment circuit of the driving device 30 is connected to the second limit switch 92 via the motor driver 32, and is driven by the movement of the plunger 92b of the second limit switch 92. The signal transmitted to the device 30 can be switched to drive or intermittent drive (stop).

  In a state where the feeding speed of the linear member W and the rotational speed of the holding portion 60a that holds the linear member W are balanced, as shown by a two-dot chain line in parentheses in FIG. The portion 91d is on the right side in contact with the linear member W, and the pressing lever portion 91b is on the right side and is set so as to be driven away from the lever 92a of the second limit switch 92.

  The rotation speed of the holding portion 60a that holds the linear member W is higher than the feeding speed of the linear member W, the feeding speed of the linear member W is increased, and the detection lever is in a relaxed state, as shown by the solid line in FIG. When the annular portion 91d of the portion 91c is released from contact with the linear member W, the detection lever portion 91c and the pressing lever portion 91b rotate clockwise. Then, the pressing lever portion 91b presses the lever 92a and the plunger 92b of the second limit switch 92, and the driving device 30 is switched so as to be intermittently driven (stopped), thereby reducing the feeding of the linear member W.

  Even with such a configuration, the feeding speed of the linear member W and the rotational speed of the holding portion 60a that holds the linear member W can be returned to a balanced state.
