Description

  The present invention relates to a feeding device and a press device unit.

  The pressing device is provided with a feeding device that sends a sheet-like member (hereinafter referred to as a workpiece) to a processing area of the pressing device. Japanese Patent Application Laid-Open No. 2009-18325 describes a feeding device that grips a workpiece by grip means and intermittently supplies the workpiece to a press device.

  The feeding device described in the document includes an apparatus main body attached to the press apparatus, a rotation drive shaft that rotates and synchronizes with a press operation by the press apparatus, and a first grip means disposed at a predetermined position of the apparatus main body. And a second grip means disposed so as to be capable of reciprocating between a forward position for feeding the workpiece and a retracted position retracted from the advanced position.

The first grip means and the second grip means operate as follows in accordance with the rotation of the rotation drive shaft. First, the second grip means grips the work and moves from the retracted position to the advanced position. During this time, the first grip means is in a state in which the grip of the workpiece is released. Next, the first grip means grips the work, and the second grip means releases the work grip. Thereafter, the second grip means moves from the forward movement position to the backward movement position. Thereby, a workpiece | work is intermittently sent to a press apparatus. And the workpiece | work sent to the press apparatus is pressed while the 2nd grip means moves from an advance position to a retreat position.
JP 2009-18325 A

  In such a feeding device, it is important to position the workpiece in order to increase the accuracy of the workpiece pressing. The workpiece is positioned by inserting a pilot pin into a pilot hole provided in the workpiece. While the workpiece is positioned, the first grip needs to perform so-called pilot release that temporarily releases the grip of the workpiece. The time and timing of pilot release (hereinafter referred to as pilot release start angle position) vary depending on the workpiece material and press working conditions. For this reason, when exchanging the workpiece or changing the machining conditions, it is necessary to adjust the pilot release start angle position.

  Conventionally, adjustment of the pilot release start angle position has been performed visually or manually, and therefore requires a lot of time. Therefore, if the adjustment of the pilot release start angle position can be simplified, the productivity can be further improved.

  An object of the present invention is to provide a feeding device in which adjustment of a pilot release start angle position is simplified.

  An exemplary first invention of the present application is a feeding device that intermittently feeds a plate-like workpiece to a press device main body, and is synchronized with the operation of the casing constituting the outer frame and the press device main body. A drive shaft that rotates about a central axis, a pilot sleeve that is installed to be rotatable relative to the drive shaft about the central axis, and a traveling direction from the feeding device toward the press device main body. A movable clamp that is installed so as to be able to reciprocate and that performs the holding and releasing operations of the workpiece in synchronism with the reciprocating motion, and is installed adjacent to the movable clamp, and in synchronization with the reciprocating motion, the workpiece A holding clamp that performs holding and releasing operations, a pilot cam that rotates about the central axis in synchronization with the pilot sleeve, and a bar that rotates about the central axis in synchronization with the drive shaft. A stop cam, a motor that is a power source different from the power source of the drive shaft, a power transmission mechanism that transmits the power of the motor to the pilot sleeve, and a control that controls the motor and the press device main body. The pilot cam and the backstop cam hold and release the fixed clamp, and the power transmission mechanism rotates the pilot sleeve relative to the drive shaft.

  By driving the motor, the relative angle of the pilot cam with respect to the backstop cam can be adjusted. Thereby, adjustment of a pilot release start angle position can be simplified.

  Hereinafter, exemplary embodiments of the present invention will be described with reference to the drawings.

<1. Configuration of feeding device>
FIG. 1 is a diagram showing a configuration of a press device unit 2 having a feeding device 1. As shown in FIG. 1, the feeding device 1 is used, for example, in the press device unit 2 and is installed adjacent to the press device main body 20. The feeding device 1 is a device that intermittently feeds a sheet-like or plate-like workpiece 3 in the traveling direction toward the press device main body 20. The press device main body 20 is a device that applies a pressure to the work 3 by moving the die up and down. The workpiece 3 sent to the press apparatus main body 20 is fixed on the fixed mold 21. And the workpiece | work 3 is processed by the movable metal mold | die 22 moving up and down.

  FIG. 2 is a schematic view of the feeding device 1. 3 is a cross-sectional view taken along line AA in FIG. As shown in FIGS. 2 and 3, the feeding device 1 includes a housing 11 that constitutes an outer frame, a drive shaft 12, a moving clamp 13, a fixed clamp 14, a pilot sleeve 15, a pilot cam 16, The back stop cam 17, the motor 19, the power transmission mechanism 40, and the control unit 50 are included.

  The drive shaft 12 is disposed vertically and horizontally with respect to the conveyance direction of the workpiece 3. The drive shaft 12 rotates around the central shaft 9 in synchronization with the vertical movement of the movable mold 22 of the press device main body 20. The moving clamp 13 and the fixed clamp 14 are adjacently disposed along the conveyance path of the workpiece 3. The fixed clamp 14 includes a first fixed grip member 141 disposed above the conveyance path of the workpiece 3 and a first movable grip member 142 disposed below the conveyance path of the workpiece 3. The first movable grip member 142 grips the workpiece 3 between the first movable grip member 142 and the first fixed grip member 141 by moving upward. Thereby, the workpiece 3 is held by the fixed clamp 14. On the other hand, when the first movable grip member 142 moves downward, the grip of the workpiece 3 is released.

  The moving clamp 13 is installed so as to be able to reciprocate along the traveling direction from the feeding device 1 toward the press device main body 20. The moving clamp 13 includes a second fixed grip member 131 disposed on the upper side and a second movable grip member 132 disposed on the lower side. The second movable grip member 132 grips the workpiece 3 between the second movable grip member 132 and the second fixed grip member 131 by moving upward. Thereby, the workpiece 3 is held by the moving clamp 13. On the other hand, when the second movable grip member 132 moves downward, the grip of the workpiece 3 is released. In addition, the moving clamp 13 moves toward the fixed clamp 14 while holding the workpiece 3. Thereby, the workpiece 3 is sent to the press apparatus main body 20.

  FIG. 4 is an operation concept diagram of the feeding device 1. The work 3 sent to the press apparatus main body 20 is first held by the moving clamp 13. At this time, the fixed clamp 14 is in a released state (a). Next, the moving clamp 13 moves toward the fixed clamp 14 while holding the workpiece 3 (b). Subsequently, the workpiece 3 is held by the fixed clamp 14 (c). Thereafter, the moving clamp 13 releases the holding of the workpiece 3 (d) and moves to the original position (e). Then, the moving clamp 13 moved to the original position holds the workpiece 3 again (f). The feeding device 1 intermittently supplies the workpiece 3 to the press device main body 20 by repeating these operations.

  The workpiece 3 is positioned between (d) and (e). The workpiece 3 is positioned by inserting a pilot pin (not shown) into a pilot hole (not shown) provided in the workpiece 3. At this time, pilot release that temporarily releases the holding of the workpiece 3 by the fixed clamp 14 is performed.

  As shown in FIGS. 2 and 3, the backstop cam 17 is fixed to the drive shaft 12. The backstop cam 17 rotates around the center shaft 9 in synchronization with the drive shaft 12. As shown in FIG. 3, the pilot sleeve 15 is installed on the outer periphery of the drive shaft 12. However, the pilot sleeve 15 can rotate relative to the drive shaft 12 around the central shaft 9. The pilot cam 16 is fixed to the pilot sleeve 15 and rotates around the central axis 9 in synchronization with the pilot sleeve 15. The pilot cam 16 is installed adjacent to the backstop cam 17 in the axial direction. The pilot release start angle position is adjusted by rotating the pilot cam 16 and adjusting the relative angle of the pilot cam 16 with respect to the backstop cam 17.

  The release operation and the holding operation of the workpiece 3 by the fixed clamp 14 are performed by the backstop cam 17, the pilot cam 16, and the first lever mechanism 61. The back stop cam 17 performs the operation of holding or releasing the workpiece 3 by the fixed clamp 14 in synchronization with the feeding of the workpiece 3 in the traveling direction. The pilot cam 16 performs a pilot release that temporarily releases the holding of the workpiece 3 by the fixed clamp 14 when the workpiece 3 is positioned. A common first driven roller 75 contacts the outer peripheral surface of the backstop cam 17 and the outer peripheral surface of the pilot cam 16.

  The first lever mechanism 61 has a first lever member 611. The first lever member 611 is attached to the housing 11 via the first pin 71 so as to be able to turn. One end of the first lever member 611 is inserted into an insertion hole 111 provided below the first movable grip member 142. A first driven roller 75 is provided at the other end of the first lever member 611. A first spring member 81 that is an elastic body is disposed between the housing 11 and the first movable grip member 142. The first spring member 81 is inserted between one end of the first lever member 611 and the housing 11 in a state where the first spring member 81 is compressed more than the natural length. Accordingly, the first spring member 81 pressurizes the first movable grip member 142 toward the first fixed grip member 141 by its repulsive force.

  Each of the backstop cam 17 and the pilot cam 16 has a valley and a peak that protrudes radially outward from the valley. When the peak portion of the backstop cam 17 or the pilot cam 16 contacts the first driven roller 75, the first lever member 611 turns clockwise in FIG. Then, the above-described one end of the first lever member 611 pushes down the first movable grip member 142 in a direction away from the first fixed grip member 141 while resisting the elastic force of the first spring member 81. Thereby, the fixed clamp 14 releases the holding of the workpiece 3.

  On the other hand, when the valley portions of the backstop cam 17 and the pilot cam 16 come into contact with the first driven roller 75, the first lever member 611 turns counterclockwise in FIG. Then, the above-described one end portion of the first lever member 611 pushes up the first movable grip member 142 by the elastic force of the first spring member 81. Then, the first movable grip member 142 moves in the direction approaching the first fixed grip member 141. Thereby, the fixed clamp 14 holds the workpiece 3.

  The release operation and the holding operation of the workpiece 3 by the moving clamp 13 are performed by the feed cam 18 and the second lever mechanism 62 provided on the drive shaft 12. The second driven roller 76 contacts the outer peripheral surface of the feed cam 18. The second lever mechanism 62 includes a second lever member 622, a third lever member 623, and a fourth lever member 624. The second lever member 622 is attached to the housing 11 through the second pin 72 so as to be rotatable. Further, the fourth lever member 624 is attached to the housing 11 through the first pin 71 so as to be able to turn.

  The end portion of the fourth lever member 624 and the end portion of the third lever member 623 are connected via a third pin 73 so as to be able to turn. The end of the second lever member 622 and the end of the third lever member 623 are connected via a fourth pin 74 so as to be able to turn. A second driven roller 76 is provided at the other end of the fourth lever member 624. A second spring member 82 that is an elastic body is disposed between the housing 11 and the end of the third lever member 623 on the second lever member 622 side. The second spring member 82 is inserted between the housing 11 and the third lever member 623 in a state where the second spring member 82 is compressed more than the natural length. Therefore, the second spring member 82 pressurizes the third lever member 623 in the traveling direction by the repulsive force. The second movable grip member 132 is supported so as to be movable in the traveling direction in synchronization with the third lever member 623.

  The outer peripheral surface of the feed cam 18 has a trough part and a peak part that protrudes radially outward from the trough part. When the peak portion of the feed cam 18 contacts the second driven roller 76, the fourth lever member 624 turns counterclockwise in FIG. Further, the second lever member 622 rotates counterclockwise in FIG. 2 while resisting the elastic force of the second spring member 82. Then, the second movable grip member 132 moves in a direction away from the second fixed grip member 131 in conjunction with the third lever member 623. Thereby, the movement clamp 13 cancels | releases holding | maintenance of the workpiece | work 3. FIG.

  On the other hand, when the valley portion of the feed cam 18 comes into contact with the second driven roller 76, the second lever member 622 rotates clockwise in FIG. 2 by the elastic force of the second spring member 82. Further, the fourth lever member 624 turns clockwise in FIG. Then, the second movable grip member 132 rises in a direction approaching the second fixed grip member 131 in conjunction with the third lever member 623. Thereby, the moving clamp 13 holds the workpiece 3.

  As shown in FIG. 3, the power transmission mechanism 40 includes a mechanism that transmits the rotational motion of the drive shaft 12 to the pilot sleeve 15, and a mechanism that converts the power of the motor 19 into the rotational motion of the pilot sleeve 15. The motor 19 is a power source different from the power source of the drive shaft 12. When the motor 19 is driven, the power of the motor is transmitted to the pilot sleeve 15 via the power transmission mechanism 40. As a result, the pilot sleeve 15 rotates relative to the drive shaft 12 around the central axis 9. The motor 19 is preferably a servo motor. However, the motor 19 may be another type of motor.

<2. Configuration of power transmission mechanism>
FIG. 5 is a diagram showing the configuration of the power transmission mechanism 40. The power transmission mechanism 40 includes a first sun gear 41, a first planetary gear 411, a second sun gear 42, a second planetary gear 422, an internal gear 43, a worm 44, and a worm wheel 45.

  The first sun gear 41 is fixed to the drive shaft 12 and rotates around the central shaft 9 in synchronization with the drive shaft 12. The first sun gear 41 has a plurality of external teeth that protrude outward in the radial direction. At least one first planetary gear 411 is disposed on the radially outer side of the first sun gear 41. The first planetary gear 411 rotates while meshing with the first sun gear 41 around the first gear pin 46 fixed to the housing 11 shown in FIG. The first gear pin 46 is fixed to the housing 11 by, for example, screwing. For this reason, the first planetary gear 411 is restricted from moving in the circumferential direction at the outer peripheral portion of the first sun gear 41. Therefore, when the drive shaft 12 rotates, the first planetary gear 411 rotates around the first gear pin 46 with the rotation of the first sun gear 41 on the radially outer side of the first sun gear 41.

  As shown in FIG. 3, the second sun gear 42 is fixed to the pilot sleeve 15 and rotates around the central shaft 9 in synchronization with the pilot sleeve 15. The second sun gear 42 has a plurality of external teeth that protrude outward in the radial direction. At least one second planetary gear 422 is disposed on the radially outer side of the second sun gear 42. The second planetary gear 422 rotates while meshing with the second sun gear 42 around a second gear pin 47 fixed to a worm wheel 45 described later. The second gear pin 47 is fixed to the worm wheel 45 by, for example, screwing.

  The internal gear 43 is located on the radially outer side of the first planetary gear 411 and the second planetary gear 422. The internal gear 43 has a plurality of internal teeth that protrude radially inward. The internal gear 43 rotates around the central axis 9 while meshing with the first planetary gear 411 and the second planetary gear 422. When the first planetary gear 411 rotates, the internal gear 43 rotates around the central shaft 9. Then, in synchronization with the rotation of the internal gear 43, the second planetary gear 422 rotates and the second sun gear 42 rotates. Then, the pilot sleeve 15 rotates in synchronization with the rotation of the second sun gear 42. Therefore, when the drive shaft 12 rotates, the backstop cam 17 and the pilot cam 16 rotate.

  Note that the tooth profile of the first planetary gear 411 and the tooth profile of the second planetary gear 422 are preferably the same as each other in order to prevent a phase error from occurring when the workpiece 3 is fed in the traveling direction. .

  In the present embodiment, as shown in FIG. 3, a first bearing 48 is provided between the internal gear 43 and the housing 11. The internal gear 43 is supported by the first bearing 48 so as to be rotatable with respect to the housing 11. In this way, the rotational rigidity of the internal gear 43 with respect to the first planetary gear 411 and the second planetary gear 422 can be increased. Therefore, the rotation can be efficiently transmitted between the rotation of the internal gear 43 and the first planetary gear 411 and the second planetary gear 422.

  The worm 44 is rotated by the power of the motor 19. The worm 44 has a spiral groove on the surface. The worm wheel 45 has a plurality of teeth on the outer periphery. When the worm 44 rotates, the spiral groove of the worm 44 and the plurality of teeth of the worm wheel 45 mesh with each other, and the worm wheel 45 rotates about the central axis 9.

  As shown in FIG. 5, the power of the motor 19 is transmitted to the worm 44 through a plurality of pulleys 441 around which an annular belt 442 is stretched. In this way, the distance between the motor 19 and the worm 44 can be increased. Therefore, the internal space of the feeder 1 can be used effectively. In particular, in the present embodiment, the motor 19 and the worm 44 are connected outside the housing 11. Further, the motor 19 and the worm 44 are disposed at positions facing each other with the worm wheel 45 interposed therebetween. Thereby, while being able to use the internal space of the feeder 1 further effectively, the feeder 1 can be reduced in size. However, the motor 19 may be directly connected to the shaft of the worm 44.

  In the present embodiment, a second bearing 49 is provided between the worm wheel 45 and the pilot sleeve 15. The worm wheel 45 is supported by the second bearing 49 so as to be rotatable with respect to the pilot sleeve 15. In this way, the worm wheel 45 can be accurately rotated with respect to the pilot sleeve 15.

  In the present embodiment, the worm wheel 45 is located between the second sun gear 42 and the pilot cam 16. In this way, the first planetary gear 411 and the second planetary gear 422 can be arranged on one side in the axial direction with respect to the worm wheel 45. Therefore, the gear can be easily incorporated, and the device cost can be reduced.

  In the present embodiment, as shown in FIG. 5, the outer peripheral portion of the worm wheel 45 is located on the radially outer side than the second planetary gear 422. Thus, if the outer diameter of the worm wheel 45 is increased, the torque for driving the worm 44 can be reduced. Thereby, the drive power of the motor 19 can be reduced.

  As shown in FIG. 3, the second gear pin 47 is fixed to the worm wheel 45. When the worm wheel 45 rotates, the second planetary gear 422 revolves around the second sun gear 42 in synchronization with the second gear pin 47. The second sun gear 42 rotates around the central axis 9 in synchronization with the revolution of the second planetary gear 422. For this reason, by driving the motor 19, the pilot sleeve 15 can be rotated without rotating the drive shaft 12. That is, the pilot cam 16 can be rotated relative to the backstop cam 17 by driving the motor 19.

  The control unit 50 is means for controlling the operation of the feeding device 1 and the press device main body 20. For the control unit 50, for example, a computer having an arithmetic processing unit such as a CPU, a memory such as a RAM, and a storage unit such as a hard disk drive is used. However, an electric circuit having an arithmetic device such as a microcontroller may be used instead of the computer.

  FIG. 6 is a diagram conceptually showing the configuration of the control system in the press apparatus unit 2. As shown in FIG. 6, the control unit 50 is electrically connected to the motor 19 and the press apparatus main body 20, respectively. The control unit 50 controls the operation of each unit based on a preset program or data such as information on molds and workpieces. In addition, the control unit 50 has a storage unit 51 that stores the rotational position of the pilot cam 16 input in advance. Then, the motor 19 and the press apparatus main body 20 are controlled based on the data indicating the rotational position read from the storage unit 51 and the computer program. Thereby, the pilot release start angle position can be adjusted based on the data stored in advance even after the die change or the workpiece change.

  FIG. 7 is a flowchart showing a flow from the die change or workpiece change (S1) to the start of press working of the press device main body 20 including the feeding device 1. When the die change or the workpiece change is performed, the feeding device 1 first drives the motor 19 (S2). Thereby, the worm 44 rotates. Then, the rotation of the worm 44 is transmitted to the pilot sleeve 15 via the worm wheel 45, the second planetary gear 422, and the second sun gear 42, and the pilot cam 16 rotates (S3). As a result, the pilot release start angle position is automatically adjusted (S4). Then, the press apparatus main body 20 is driven (S5), and the press work is resumed (S6). Thereby, adjustment of a pilot release start angle position can be simplified.

<3. Modification>

  In the above embodiment, the press device main body 2 is a press device using a crank system that converts the rotational movement of the crankshaft into the vertical movement of the mold. However, the press device main body may use other methods such as a link method and a cam method. The press device main body may be a hydraulic or pneumatic press device. In addition, the press device main body may be used, for example, for manufacturing electronic parts such as connectors, or may be used for manufacturing press products other than electronic parts.

  Further, the structure of the power transmission mechanism that transmits the power of the motor to the pilot sleeve may be different from that of the above embodiment.

  Moreover, about the detailed shape of each member, you may differ from the shape shown by each figure of this application. Moreover, you may combine suitably each element which appeared in said embodiment and modification in the range which does not produce inconsistency.

  The present invention can be used in a press device.
