When the turntable is lifted by the lifter, it is located at a position where it can be connected to the connecting body so that power can be transmitted, and the rotation of the rotating body is transmitted as the rotation of the connecting body. The driving force of the transport device drive source is transmitted as the rotation of the connecting body through the shaft and the rotating body, and the top plate rotates with the rotation of the connecting body. .

  As shown in FIG. 2, a lifter 30 made of a lift cylinder is disposed between the pair of frames 13, and a turntable 40 is disposed above the lifter 30. The lifter 30 is driven by a lifter drive unit 31. As shown in FIGS. 1 and 3, the turntable 40 includes a connecting plate 41 as a connecting body formed in a disc shape, and a top plate 43 supported above the connecting plate 41 via a support member 42. And is formed from. The connecting plate 41 and the top plate 43 are integrated by the support member 42, and when the connecting plate 41 rotates, the top plate 43 also rotates.

  The tip of the piston rod 32 in the lifter 30 is connected to the lower surface of the connecting plate 41, and the connecting plate 41 is supported so as to be rotatable with respect to the piston rod 32. Therefore, the entire turntable 40 is moved up and down as the connecting plate 41 is moved up and down by the lifting and lowering of the piston rod 32 in the lifter 30. When the turntable 40 is raised, the upper surface of the top plate 43 is positioned above the chain 14 (see FIG. 7).

  Between the upper surface of the connecting plate 41 and the lower surface of the top plate 43, a position for supporting the rotating shaft 25 is set so that the rotating body 27 enters. Here, as shown by a two-dot chain line in FIG. 1, when a virtual line extending along the conveyance direction and passing through a point on the peripheral surface of the connecting plate 41 is defined as a tangent F of the connecting plate 41, the rotating body 27 (rotating The shaft 25) is disposed at a position where the axial direction of the rotating body 27 (the rotating shaft 25) extends in a direction orthogonal to the tangent line F (direction indicated by the arrow Y2). More specifically, the rotating body 27 is arranged at a position where the axial direction extends along the radial direction of the connecting plate 41 and is parallel to the direction in which the shaft 20 extends. In addition, the rotating body 27 is disposed at a position where the rotating body 27 is connected to the connecting plate 41 raised by the lift of the lifter 30 so that power can be transmitted, and the rotation of the rotating body 27 is transmitted as the rotation of the connecting plate 41. Is arranged.

  The turntable 40 is controlled in the amount of ascending so that the upper surface of the connecting plate 41 rises to a position where it is pressed against the outer peripheral surface of the rotating body 27. When the outer peripheral surface of the rotating body 27 is in pressure contact with the upper surface of the connecting plate 41, the rotation of the rotating body 27 is transmitted to the connecting plate 41 so that the connecting plate 41 rotates.

  Further, the chain conveyor 11 is provided with a stopper 28 for stopping the conveyed load W at an upper position (predetermined position) of the top plate 43. The stopper 28 is formed of a flat plate and is fixed to a piston rod of an air cylinder (not shown). The stopper 28 is configured to be disposed at a blocking position where the stopper 28 protrudes so as to come into contact with the load W and a standby position where the load W can pass upward by the operation of the air cylinder.

  Next, the electrical configuration of the turntable device 10 will be described. As shown in FIG. 5, the turntable device 10 includes a control unit 45, to which the conveyance motor 17, the stopper 28, and the lifter drive unit 31 are signal-connected. Further, the turntable device 10 includes a first sensor 51 as a first detection unit that detects that the load W has been conveyed to a position above the top plate 43 (predetermined position). As shown in FIG. 1, the first sensor 51 is a photoelectric sensor composed of a projector 51a provided outside one frame 13, and a light receiver 51b provided outside the other frame 13 so as to face the projector 51a. It consists of a sensor. The first sensor 51 is signal-connected to the control unit 45, and when the load W is positioned between the projector 51a and the light receiver 51b, the first sensor 51 outputs a detection signal of the load W to the control unit 45. Yes.

  Furthermore, as shown in FIG. 5, the turntable device 10 includes a second sensor 52, and this second sensor 52 is configured when the connecting plate 41 and the rotating body 27 can transmit power, that is, the connecting plate. It is detected that 41 can be pressed against the rotating body 27. As shown in FIG. 2, the second sensor 52 includes a projector 52a provided on one frame 13, and a light receiver provided on the other frame 13 so as to face the projector 52a as shown in FIG. It consists of a photoelectric sensor consisting of 52b. The second sensor 52 is signal-connected to the control unit 45, and the second sensor 52 outputs a detection signal to the control unit 45 when the connecting plate 41 is positioned between the projector 52a and the light receiver 52b. . The position where the second sensor 52 is provided is a position where the connection plate 41 can be detected when the upper surface of the connection plate 41 is in pressure contact with the outer peripheral surface of the rotating body 27. In the present embodiment, the position is provided below the lower surface of the frame 13. It has become.

  Further, as shown in FIG. 5, the turntable device 10 includes a third sensor 53, and the third sensor 53 detects that the connecting plate 41 of the turntable 40 has rotated 90 degrees. As shown in FIG. 1, the third sensor 53 includes a detected portion 53 a provided on the peripheral surface of the connecting plate 41 and a detecting portion 53 b provided on one frame 13 for detecting the detected portion 53 a. The third sensor 53 is signal-connected to the control unit 45. Four detected portions 53a are provided on the peripheral surface of the connecting plate 41, and the four detected portions 53a are provided at positions shifted by 90 degrees along the circumferential direction of the connecting plate 41. And if the to-be-detected part 53a is located in the position which the connection board 41 rotates and faces the detection part 53b, a detection signal will be output to the control part 45 from the 3rd sensor 53. FIG.

  Next, a method of changing the direction (rotation) of the load W by the turntable device 10 having the above configuration will be described. As shown in FIG. 6, the load W is transported by the chain conveyor 11 so that the barcode Wa faces the upstream side in the transport direction. Then, in order to read the bar code Wa of the load W with a bar code reader R provided on the outer side of the frame 13, the direction of the load W is changed by the turntable 40.

  When the load W is placed on the chain 14, the controller 45 drives the transport motor 17. When the driving shaft 17a is rotated by the driving force of the conveying motor 17, the driving sprocket 18 is rotated, and the rotation of the driving sprocket 18 is transmitted to the shaft 20 via the transmission chain 23 and the first sprocket 21a. It rotates in the same direction as the drive shaft 17a. Then, the second sprocket 22 is rotated, the chain 14 is rotated by the rotation of the second sprocket 22, and the load W supported by the chain 14 is transported from the upstream in the transport direction to the downstream.

  Further, when the shaft 20 is rotated by the driving force of the conveying motor 17, the first sprocket 21 b is rotated, and the rotation of the shaft 20 is transmitted to the rotating shaft 25 via the connecting chain 29 and the rotating shaft sprocket 26. As the shaft 25 rotates, the rotating body 27 rotates in the same direction as the drive shaft 17a. At this time, the turntable 40 does not rise, and the turntable 40 does not rotate because the upper surface of the connecting plate 41 is not pressed against the rotating body 27.

  When the load W is conveyed by the chain conveyor 11 and the load W passes between the light projector 51a and the light receiver 51b of the first sensor 51 and is conveyed to a predetermined position, a detection signal is sent from the first sensor 51 to the control unit 45. Is output. The controller 45 raises the stopper 28 from the standby position and moves it to the blocking position. Then, the movement of the load W is stopped by the stopper 28 and the load W is arranged at an upper position of the turntable 40. When the load W is transported to a predetermined position (above the top plate 43) and a detection signal is output from the first sensor 51 to the control unit 45, the control unit 45 is triggered by the detection of the first sensor 51. Control to stop the driving of the motor 17 is performed. As a result, the circulation of the chain 14 on the chain conveyor 11 is stopped, and the conveyance of the load W is stopped. At this time, the control unit 45 performs control to place the stopper 28 at the standby position.

  Next, after the conveyance motor 17 stops, the control unit 45 controls the lifter driving unit 31 to raise the lifter 30. Then, as shown in FIG. 7, the turntable 40 moves upward, the connecting plate 41 passes between the light projector 52a and the light receiver 52b of the second sensor 52, and the detection signal is transmitted from the second sensor 52 to the control unit. When output to 45, the control unit 45 stops the drive of the lifter drive unit 31. Then, the turntable 40 is disposed at a position where the upper surface of the connecting plate 41 is in pressure contact with the outer peripheral surface of the rotating body 27, and the load W is supported on the top plate 43. When the load W is supported on the top plate 43, the load W is lifted above the chain 14 by the top plate 43.

  Further, when the upper surface of the connecting plate 41 is in pressure contact with the outer peripheral surface of the rotating body 27, the rotating body 27 and the connecting plate 41 can transmit power, and a detection signal is output from the second sensor 52 to the control unit 45. The control unit 45 drives the conveyance motor 17. When the shaft 20 is rotated by the driving force of the conveying motor 17, the first sprocket 21b is rotated, and the rotation of the shaft 20 is transmitted to the rotating shaft 25 via the connecting chain 29 and the rotating shaft sprocket 26, thereby rotating the rotating shaft. The rotating body 27 rotates through 25. When the rotating body 27 rotates, the rotation of the rotating body 27 is transmitted to the connecting plate 41, the connecting plate 41 rotates, and the load W rotates.

  As shown in FIG. 8, when the turntable 40 rotates 90 degrees and the detected portion 53a of the third sensor 53 reaches a position facing the detecting portion 53b, a detection signal is output from the third sensor 53 to the control portion 45. Is done. The controller 45 stops the driving of the transport motor 17. Then, the load W is turned to a position rotated 90 degrees by the turntable 40, and the barcode Wa is arranged at a position facing the barcode reader R. For this reason, the barcode Wa can be read by the barcode reader R.

According to the above embodiment, the following effects can be obtained.
(1) The turntable device 10 includes a shaft 20 that is rotated by the driving force of the conveying motor 17 and a rotating body 27 that is rotated by the rotation of the shaft 20, and the rotating body 27 can rotate in the same direction as the shaft 20. It has become. Further, the connecting plate 41 of the turntable 40 raised by the lifter 30 can be pressed against the rotating body 27, and when the connecting plate 41 is pressed into contact with the rotating body 27, the rotation of the rotating body 27 is applied to the connecting plate 41. The turntable 40 can be rotated by being transmitted. Therefore, the turntable device 10 uses the same driving source for the chain conveyor 11 and the turntable 40 to convey the load W by the chain conveyor 11 and rotate the load W by the turntable 40. Can only be done. Therefore, each of the three operations of transporting the load W by the chain conveyor 11, raising and lowering the load W by the lifter 30, and rotating the load W by the turntable 40 is performed as compared with a case where a drive source provided for executing each operation is performed. The drive source for rotating the load W can be reduced, and the manufacturing cost of the turntable device 10 can be reduced. Furthermore, since the number of driving sources is reduced by one as compared with the configuration in which a driving source is required for performing three operations, the number of wirings for electrically connecting each driving source to the power source and the movable body is reduced. The installation cost can be reduced by reducing the wiring material cost and the wiring man-hours in the turntable device 10.

  (2) Although the load W is rotated by the turntable 40 so that the direction of the barcode Wa is opposed to the barcode reader R, the load W may be conveyed in a state where it is not necessary to rotate. The rotation of the table 40 is not always a necessary operation. Therefore, the drive source for rotating the turntable 40 is also used as the conveyance motor 17, so that the drive source that is not always required can be omitted, and the manufacturing cost of the turntable device 10 can be suitably reduced.

  (3) Since the rotating body 27 is formed of a rubber material, the frictional force generated between the outer peripheral surface of the rotating body 27 and the upper surface of the connecting plate 41 is increased, and the rotation of the rotating body 27 is reliably transmitted to the connecting plate 41. be able to.

  (4) The rotating body 27 is formed in a cylindrical shape, and the rotation of the rotating body 27 is transmitted to the connecting plate 41 only by the frictional force generated between the outer peripheral surface of the rotating body 27 and the upper surface of the connecting plate 41. Here, for example, if a gear is provided on the outer peripheral surface of the rotating body 27 and a gear on the upper surface of the connecting plate 41 and the rotation of the rotating body 27 is transmitted to the connecting plate 41 by meshing both gears, If the gears do not mesh correctly, the rotation of the rotating body 27 may not be transmitted to the connecting plate 41. Therefore, the rotation of the rotating body 27 is connected by transmitting the rotation of the rotating body 27 to the connecting plate 41 only by the frictional force between the cylindrical rotating body 27 and the connecting plate 41 as in this embodiment. Transmission to the plate 41 can be ensured.

  (5) The turntable device 10 can carry the load W by the chain conveyor 11 and rotate the load W by the turntable 40 only by the driving force of the carrying motor 17. For this reason, it is not necessary to connect a drive source to a movable body such as the turntable 40, and it is not necessary to consider the contact of the wiring with respect to the rotation of the turntable 40. Can be greatly simplified.

  (6) The turntable device 10 can perform the conveyance of the load W by the chain conveyor 11 and the rotation of the load W by the turntable 40 only by the driving force of the conveyance motor 17. No source is needed. Therefore, maintenance inspection items for the turntable 40 can be reduced, and maintenance inspection items for the entire turntable device 10 can be reduced.

  (7) The turntable device 10 uses the drive source of the turntable 40 for rotating the load W as the conveyance motor 17 for driving the chain conveyor 11. The turntable 40 of the present embodiment is provided only for rotating the top plate 43 and has a simple configuration. Therefore, even if the conveyance motor 17 is used as a drive source for the turntable 40, the overall structure of the turntable device 10 does not have to be complicated. On the other hand, in the turntable device of Patent Document 1, the drive source for rotating the turntable and the roller conveyor is the same, and in order to enable the rotation of the roller conveyor, an output shaft, a bearing member, a differential device, etc. A large number of members are required and the configuration is very complicated. Therefore, the turntable device 10 of the present embodiment has a simple configuration, but can rotate the turntable 40 and drive the chain conveyor 11 by the transport motor 17.

  (8) The rotating body 27 is disposed so that the axial direction thereof is orthogonal to the tangent line F of the connecting plate 41 and extends along the radial direction of the connecting plate 41, and the axial direction of the rotating body 27 is the shaft 20. It is arranged at a position parallel to the extending direction. For this reason, a part of the rotation direction of the connecting plate 41 matches along the direction orthogonal to the axial direction of the rotating body 27, and the connecting plate 41 can be rotated by the rotation of the rotating body 27.

In addition, you may change the said embodiment as follows.
The power transmission between the connecting plate 41 and the rotating body 27 may be performed by meshing of gears formed on the upper surface of the connecting plate 41 and the outer peripheral surface of the rotating body 27 so that they can be engaged with each other. May be used.

The conveying device is not limited to the conveying method such as the chain conveyor 11 but may be another conveying method such as a roller conveyor.
○ An extruding device that arranges another conveying device in a direction orthogonal to the conveying direction of the load W in the turntable device 10 and further pushes the load W toward another conveying device to the side of the turntable device 10 Is provided. Then, the load W whose direction has been changed by the turntable device 10 may be pushed out to another transport device by the extrusion device, and the load W may be transported by another transport device. That is, you may use the turntable apparatus 10 of this embodiment as a direction change machine of the load W. FIG.

  The direction change of the conveyed product performed by the turntable device 10 may be performed so that the fork of the forklift can be inserted into the fork insertion hole of the pallet as the conveyed product.

  The transfer motor 17 may be a hollow shaft motor, and the shaft 20 may be directly rotated by the motor. Alternatively, the conveyance motor 17 may be disposed outside the frame 13 and the drive shaft 17a itself may be a shaft. The conveyance device drive source may be a drive source other than the motor.

The connecting body may be other than the connecting plate 41 having a plate shape.
The first to third sensors 51 to 53 are not limited to photoelectric sensors, but may be other types of sensors.

○ The turn of the turntable 40 may be rotated 180 degrees.
In the chain conveyor 11 of the turntable device 10, the support shaft 16 that connects the sprockets 15 may not be provided. Or in the chain conveyor 11, the one spindle 16 located in the upstream of a conveyance direction may serve as the shaft.
