JP 2003-340655 A

In the component supply apparatus of Patent Document 1, the two transfer units are reciprocated by power from different power sources. Therefore, there is a possibility that the energy consumed by the component supply device when supplying the components increases. In addition, since the power source is provided for each of the two transfer units, there is a possibility that the component supply device is enlarged. If the two transfer units are driven by a single power source, it is difficult to reciprocate each of the two transfer units at different arbitrary cycles.
Moreover, in the component supply apparatus of patent document 1, since the motive power source is arrange | positioned with respect to the transfer part which reciprocates vertically, a vertical direction physique of a component supply apparatus, ie, height, May grow.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a small component supply device with low energy consumption.

The present invention is a component supply device that supplies a component to a supply position, and includes a storage unit, a first transfer unit, a second transfer unit, a third transfer unit, a fourth transfer unit, a power source, a first drive unit, and a first drive unit. 2 drive units.
The storage unit stores parts. The first transfer unit is provided in the storage unit so as to be able to reciprocate in a predetermined direction, and by reciprocating, the parts stored in the storage unit can be transferred from the first position to the second position.

  The second transfer unit can transfer the component transferred to the second position by the first transfer unit to the third position. The third transfer unit is provided so as to be able to reciprocate in a predetermined direction at the third position. By reciprocating, the part transferred to the third position by the second transfer unit can be transferred to the fourth position. The fourth transfer unit can transfer the component transferred to the fourth position by the third transfer unit to the supply position.

  The power source can output power. The first driving unit reciprocates the first transfer unit by being driven by power output from the power source. The second drive unit reciprocates the third transfer unit by being driven by power output from the power source.

  As described above, in the present invention, the first transfer unit and the second transfer unit can reciprocate in a predetermined direction by the power output from one power source. That is, in the present invention, the two transfer units (the first transfer unit and the third transfer unit) can be reciprocated by the power from one power source. Therefore, the energy consumed by the component supply device when supplying the component to the supply position can be reduced. In addition, since there is one power source for reciprocating the two transfer units (the first transfer unit and the third transfer unit), compared to the conventional configuration in which a power source is provided for each of the two transfer units, the component supply device The overall physique can be reduced.

The inclined surface 36 is inclined so as to descend downward in the vertical direction as it goes toward the y direction, that is, toward the plate portion 27 side. Moreover, the 4th transfer part 34 has the horizontal surface 38 parallel with respect to xy plane between the inclined surface 37 and the board part 27 (refer FIG. 4, 5).

  The actuator 10 is attached to the support portion 4 fixed to the end portion of the base 3 in the x direction (see FIG. 1). The actuator 10 includes a motor 11 and an output shaft 12. In the present embodiment, the motor 11 is a stepping motor, for example. The power (rotation) of the motor 11 is output from the output shaft 12 via, for example, a speed reducer. That is, the output shaft 12 outputs the power of the motor 11 by rotating around the axis.

  In the present embodiment, the power output from the actuator 10 is input to the power transmission unit 80. The power transmission unit 80 includes a plurality of pulleys, a belt member wound around the pulleys, and the like. When power (rotation) is input to a certain pulley, the power is transmitted to another pulley via a belt member. The power transmission unit 80 transmits the power input from the actuator 10 to the first drive unit 40 and the second drive unit 60 described later.

In the present embodiment, the first drive unit 40 is provided on the lower side in the vertical direction with respect to the first transfer unit 31. The first drive unit 40 includes a link shaft member 41, a first moving unit 42, a second moving unit 43, a link mechanism unit 50, and the like.
The link shaft member 41 is formed in a rod shape and is provided in the vicinity of the base 3 so that the axial direction is parallel to the x-axis. The link shaft member 41 is supported by the support portion 5 fixed to the base 3 so as to be rotatable about the axis. The end of the link shaft member 41 opposite to the support portion 5 is connected to the power transmission portion 80. A screw thread is formed on the outer wall of the link shaft member 41. When the power output from the actuator 10 is input to the end via the power transmission unit 80, the link shaft member 41 is driven to rotate about the axis.

  The first moving part 42 is provided on the link shaft member 41. The 1st moving part 42 is provided so that the link shaft member 41 may be located inside. On the inner wall of the first moving part 42, a thread groove is formed in which the thread of the link shaft member 41 can mesh. Accordingly, when the link shaft member 41 rotates in one direction around the axis, the link shaft member 41 moves to one side (x direction) of the link shaft member 41, and when the link shaft member 41 rotates in the other direction around the axis, the link shaft member 41 moves to the other side in the axial direction (the direction opposite to the x direction).

  The second moving unit 43 is provided on the link shaft member 41. The 2nd moving part 43 is provided so that the link shaft member 41 may be located inside. The second moving unit 43 is provided on the power transmission unit 80 side with respect to the first moving unit 42. On the inner wall of the second moving part 43, a thread groove is formed in which the thread of the link shaft member 41 can mesh. Accordingly, when the link shaft member 41 rotates in one direction around the axis, the link shaft member 41 moves to the other side (the opposite side to the x direction) of the link shaft member 41 so as to approach the first moving portion 42, and the link shaft member 41. When the shaft rotates in the other direction around the axis, the link shaft member 41 moves to one side (x direction) in the axial direction so as to move away from the first moving portion 42.

  The link mechanism unit 50 includes a link member 51, link nodes 52, 53, and the like. A plurality of link members 51 are formed in a rod shape. The link nodes 52 connect the centers of the link members 51 so that the two link members 51 can rotate relative to each other. The link node 53 connects the ends of the link members 51 so that the two link members 51 can rotate relative to each other. As described above, one link mechanism portion 50 is formed by the plurality of link members 51 and the link nodes 52 and 53. The link mechanism 50 is a so-called “multi-node link mechanism”.

In the present embodiment, two link mechanism portions are formed such that one link mechanism portion 50 is formed by the six link members 51, the three link nodes 52, and the six link nodes 53, and the link shaft member 41 is positioned therebetween. 50 is provided (see FIGS. 5, 6, and 7).
One end of the link mechanism 50 in the vertical direction, that is, the end opposite to the link node 53 of the two link members 51 can rotate relative to the first moving part 42 and the second moving part 43, respectively. The first moving unit 42 and the second moving unit 43 are connected to each other.

  On the other end side in the vertical direction of the link mechanism unit 50, that is, on the side opposite to the first moving unit 42 and the second moving unit 43, a rectangular plate-shaped base unit 44 is provided. The base part 44 is provided so as to be connected to the side opposite to the inclined surface 35 of the first transfer part 31. Therefore, the base part 44 can be reciprocated in the vertical direction together with the first transfer part 31. The other end side in the vertical direction of the link mechanism 50, that is, the end opposite to the link node 53 of the two link members 51 on the base 44 side, can be moved relative to the base 44. Connected to the unit 44.

  With the above configuration, when the first moving unit 42 and the second moving unit 43 move closer to each other, the link mechanism unit 50 extends in the vertical direction so that the one end side and the other end side move away from each other, and the first moving unit 42 and the first moving unit 42 When the two moving parts 43 move away from each other, the one end side and the other end side contract in the vertical direction so as to approach each other. Therefore, when the link shaft member 41 rotates in one direction around the axis by the power output from the actuator 10, the first moving unit 42 and the second moving unit 43 move so as to approach each other, and the link mechanism unit 50 has one end The first transfer portion 31 moves upward in the vertical direction, extending in the vertical direction so that the side and the other end side move away from each other. On the other hand, when the link shaft member 41 is rotated in the other direction around the axis by the power output from the actuator 10, the first moving part 42 and the second moving part 43 move away from each other, and the link mechanism part 50 has one end The first transfer section 31 moves downward in the vertical direction by contracting in the vertical direction so that the side and the other end side approach each other.

In the present embodiment, the second drive unit 60 is provided on the lower side in the vertical direction with respect to the third transfer unit 33. The second drive unit 60 includes a crankshaft member 61, a crank mechanism unit 70, a guide unit 62, and the like.
The crankshaft member 61 is formed in a rod shape and is provided so that the axial direction is parallel to the y-axis. The crankshaft member 61 is supported by the support portion 6 fixed to the base 3 so as to be rotatable about the axis. One end of the crankshaft member 61 is connected to the power transmission unit 80. When the power output from the actuator 10 is input to the end via the power transmission unit 80, the crankshaft member 61 is driven to rotate about the axis.

The crank mechanism unit 70 includes a first crank member 71, a second crank member 72, and the like.
The first crank member 71 is formed in a rod shape, and one end thereof is connected to the other end of the crankshaft member 61 so as to be orthogonal to the crankshaft member 61. Therefore, when the crankshaft member 61 rotates around the axis, the first crank member 71 rotates together with the crankshaft member 61 so that the other end moves in the circumferential direction of the crankshaft member 61.

The second crank member 72 is formed in a rod shape, and has one end connected to the other end of the first crank member 71 so as to be rotatable relative to the first crank member 71, so as to be rotatable relative to the third transfer portion 33. The other end is connected to the third transfer unit 33.
The guide part 62 is provided between the third transfer part 33 and the support part 6. The guide unit 62 regulates the moving direction of the third transfer unit 33 so that the third transfer unit 33 can move only in the vertical direction.

  With the above configuration, when the power output from the actuator 10 is input to one end of the crankshaft member 61 via the power transmission unit 80, the crankshaft member 61 rotates around the axis together with the first crank member 71. Thereby, the power when the first crank member 71 rotates is transmitted to the third transfer part 33 via the second crank member 72. As a result, the third transfer part 33 is guided by the guide part 62 and reciprocates in the vertical direction.

  The control unit 13 is a computer having a CPU, a ROM, a RAM, an I / O, and the like, for example. The control unit 13 can control the operation of the actuator 10 and the actuators that vibrate the second transfer unit 32 and the fourth transfer unit 34 by performing calculations with the CPU according to a program stored in the ROM.

  The control unit 13 can control the operation of the motor 11 so that the rotation direction of the output shaft 12 of the actuator 10 is an arbitrary direction and the rotation number is an arbitrary rotation number. Further, the control unit 13 controls the operation of the actuator that vibrates the second transfer unit 32 and the fourth transfer unit 34 to vibrate the second transfer unit 32 and the fourth transfer unit 34 at an arbitrary frequency. Can do.

  In the present embodiment, the sensor 14 is provided on the upper side in the vertical direction with respect to the second transfer portion 32 of the plate portion 26 (see FIGS. 1, 2, 4, and 5). The sensor 14 detects the amount of the component 100 on the second transfer unit 32 and outputs a signal related to the detected amount of the component 100 to the control unit 13. Thereby, the control unit 13 can detect the amount of the component 100 on the second transfer unit 32.

Next, the operation | movement of the components supply apparatus 1 is demonstrated based on FIGS.
The initial state of the component supply apparatus 1 is shown in FIG. Moreover, the state of the component supply apparatus 1 when the 1st transfer part 31 and the 3rd transfer part 33 are each located in the vertical direction uppermost side among the reciprocation possible ranges is shown in FIG. Further, in FIG. 8, the position in the vertical direction of the upper end portion (vertical upper end portion) of the first transfer unit 31 in the initial state is indicated by a straight line L1, and is located at the uppermost vertical direction in the reciprocable range. The position in the vertical direction of the upper end portion of the first transfer unit 31 when doing this is indicated by a straight line L2. Further, in FIG. 8, the position in the vertical direction of the upper end portion of the third transfer unit 33 in the initial state is indicated by a straight line L3, and the third transfer unit 33 when located at the uppermost vertical direction in the reciprocable range. The position in the vertical direction of the upper end of the line is indicated by a straight line L4.

  As shown in FIG. 1, a plurality of components 100 are stored in the storage unit 20 in the initial state. In this embodiment, since the 1st transfer part 31 has the inclined surface 35, the components 100 are stored in the state which leaned to the board part 24 side (refer FIG. 2, 5, 6). At this time, the position where the component 100 is stored is defined as a first position P1. In FIG. 1, for convenience, the first position P1 is indicated by a circular broken line near the center of the first transfer unit 31 in the x direction. However, the first position P1 is the first transfer unit 31 in the x direction. Any position can be the first position P1 as long as it is on the inclined surface 35 of the first transfer part 31 as well as the vicinity of the center.

  When the output shaft 12 of the actuator 10 is rotated in one direction around the axis by the control unit 13, power (rotation) is output from the output shaft 12, and the power is transmitted to the first drive unit 40 via the power transmission unit 80. Is done. When the first drive unit 40 is driven by the power output from the actuator 10, the first transfer unit 31 moves upward in the vertical direction from the position of the straight line L1. The power output from the actuator 10 is transmitted to the first drive unit 40 via the power transmission unit 80 and also to the second drive unit 60.

  When the output shaft 12 of the actuator 10 continues to rotate in one direction around the axis (rotates a plurality of times), the first transfer unit 31 continues to move upward in the vertical direction, and the position of the straight line L2 shown in FIG. Move up. Since the inclined surface 35 is formed in the first transfer unit 31, when the first transfer unit 31 moves to the position of the straight line L <b> 2, the component 100 falls over the plate part 24 to the second transfer unit 32. At this time, the position where the component 100 falls is defined as a second position P2. 1 and 8, for convenience, the second position P2 is indicated by a circular broken line in the vicinity of the center in the x direction of the second transfer part 32. However, as the second position P2, the x of the second transfer part 32 is indicated. Any position in the x direction (longitudinal direction) of the second transfer part 32 can be the second position P2 without being limited to the vicinity of the center of the direction.

  Here, when the second transfer unit 32 is vibrated by the control unit 13, the component 100 moves on the second transfer unit 32 in the x direction, that is, toward the third transfer unit 33. Thereby, the component 100 falls from the second transfer unit 32 to the inclined surface 36 of the third transfer unit 33. At this time, the position where the component 100 falls is defined as a third position P3.

  As described above, the power output from the actuator 10 is transmitted to the first drive unit 40 and also to the second drive unit 60 via the power transmission unit 80. When the second drive unit 60 is driven by the power output from the actuator 10, the third transfer unit 33 moves upward in the vertical direction from the position of the straight line L3.

When the output shaft 12 of the actuator 10 rotates in one direction around the axis, the crankshaft member 61 rotates in one direction around the axis. Thereby, the 3rd transfer part 33 moves to the position of straight line L4 of the perpendicular direction upper part (refer to Drawing 8). Since the inclined surface 36 is formed in the third transfer part 33, when the third transfer part 33 moves to the position of the straight line L 4, the component 100 passes over the plate part 26 and the inclined surface of the fourth transfer part 34. It moves to the horizontal plane 38 via 37. At this time, the position where the component 100 moves is set as a fourth position P4 (see FIGS. 2 and 4).
Here, when the fourth transfer unit 34 is vibrated by the control unit 13, the component 100 moves in the direction opposite to the x direction while being aligned on the fourth transfer unit 34. As a result, the component 100 moves from the fourth position P4 to the supply position PS.

  In this way, the component supply device 1 drives the first drive unit 40 and the second drive unit 60 with the power output from the actuator 10 to move the first transfer unit 31 and the third transfer unit 33 in the vertical direction, By vibrating the second transfer unit 32 and the fourth transfer unit 34, the component 100 stored in the storage unit 20 is passed from the first position P1 to the second position P2, the third position P3, and the fourth position P4. It can be supplied to the supply position PS.

  In addition, while the output shaft 12 of the actuator 10 rotates in one direction around the axis, the first shaft 31 moves from the position of the straight line L1 to the position of the straight line L2. Rotate multiple times. Therefore, at this time, that is, while the first transfer unit 31 moves from the position of the straight line L1 to the position of the straight line L2, the third transfer unit 33 is between the position of the straight line L3 and the position of the straight line L4 at a predetermined cycle. Move back and forth.

  When the control unit 13 detects that the amount of the component 100 on the second transfer unit 32 is greater than or equal to a predetermined amount by the sensor 14 when the first transfer unit 31 moves to the position of the straight line L2, the output shaft 12 Controls the actuator 10 to rotate in the other direction around the axis. Thus, after a part of the plurality of components 100 on the first transfer unit 31 falls on the second transfer unit 32, the first transfer unit 31 moves downward in the vertical direction. Thereby, the falling of the component 100 from the first transfer unit 31 to the second transfer unit 32 is stopped, and the component 100 on the second transfer unit 32 overflows the plate unit 26 to the fourth transfer unit 34 side. Can be suppressed. When the actuator 10 is controlled so that the output shaft 12 rotates in the other direction around the axis, and the first transfer unit 31 moves downward in the vertical direction, the crankshaft member 61 of the second drive unit 60 moves around the axis. Rotate in the other direction. Therefore, at this time, the third transfer unit 33 reciprocates between the position of the straight line L3 and the position of the straight line L4 at a predetermined cycle, similarly to the case where the first transfer unit 31 moves upward in the vertical direction.

  In the present embodiment, when the control unit 13 detects that the amount of the component 100 on the second transfer unit 32 is equal to or greater than a predetermined amount by the sensor 14, the first transfer unit 31 is vertically below the straight line L2. The actuator 10 is controlled to reciprocate at a predetermined cycle at a position separated by a predetermined distance. That is, at this time, the control unit 13 controls the actuator 10 so that the output shaft 12 rotates alternately in one direction or the other direction around the axis. At this time, the crankshaft member 61 of the second drive unit 60 also rotates alternately in one direction or the other direction around the axis. Therefore, the end of the first crank member 71 opposite to the crankshaft member 61 rotates alternately in one direction or the other direction in the circumferential direction of the crankshaft member 61. Thereby, the 3rd transfer part 33 reciprocates between the position of the straight line L3 and the position of the straight line L4 with a predetermined | prescribed period similarly to when the 1st transfer part 31 moves to a perpendicular direction. In this way, the control unit 13 controls the actuator 10 so that the rotation direction of the output shaft 12 changes, thereby causing the first transfer unit 31 and the third transfer unit 33 to reciprocate at different periods, The component 100 can be transferred from the third transfer unit 33 to the fourth transfer unit 34 while adjusting the amount of the component 100 transferred from the first transfer unit 31 to the second transfer unit 32.

  As described above, in the present embodiment, (1) the storage unit 20 stores the component 100. The first transfer unit 31 is provided in the storage unit 20 so as to be able to reciprocate in a predetermined direction. By reciprocating, the component 100 stored in the storage unit 20 can be transferred from the first position P1 to the second position P2. It is.

  The second transfer unit 32 can transfer the component 100 transferred to the second position P2 by the first transfer unit 31 to the third position P3. The third transfer unit 33 is provided so as to be reciprocally movable in a predetermined direction at the third position P3. By reciprocating, the third transfer unit 33 transfers the component 100 transferred to the third position P3 by the second transfer unit 32 to the fourth position P4. Can be transported up to. The fourth transfer unit 34 can transfer the component 100 transferred to the fourth position P4 by the third transfer unit 33 to the supply position PS.

  The actuator 10 can output power. The first drive unit 40 reciprocates the first transfer unit 31 by being driven by the power output from the actuator 10. The second drive unit 60 reciprocates the third transfer unit 33 by being driven by the power output from the actuator 10.
