The electromagnetic proportional relief valve is provided with a cut valve in parallel. An air distribution pipe communicating with the pneumatic pump is joined to the rear end portion of the cylinder portion through an electromagnetic valve.
In addition, since the 2nd cushion apparatus 26 shown in FIG. 5 is the same structure as the 1st cushion apparatus 22, the description is abbreviate | omitted.

Next, the operation of the cart transport apparatus configured as described above will be described below.
First, as shown in FIG. 1, in the first traverser transfer device 7, the arm member 54 is rotated toward the first carry-out position 11, and the empty movable carriage 42 is positioned at the first carry-out position 11. Has been. As shown in FIG. 3, the transfer table rail 48 is aligned with the carriage rail 32 of the first conveyance path 6.

  In the second traverser transfer device 9, the arm member 76 is rotated toward the first carry-in position 17, and the transfer carriage 42 on which the surface plate carriage 4 is placed is positioned at the first carry-in position 17. Although not shown, the transfer table rail 48 is aligned with the carriage rail 32 of the first transport path 6.

  Next, the drive mechanism 88 of the first extrusion device 20 is driven to move the push member 86 forward, so that the rear end portion of the surface plate carriage 4 positioned at the first carry-in position 17 in the second traverser transport device 9. To push. Since a plurality of the platen carts 4 are arranged in series, the front end portion of the leading platen cart 4 at the downstream end position 10 abuts against the buffer portion 92 of the piston portion 94 extended from the cushion device 22. . Therefore, the plurality of surface plate carts 4 on the first conveyance path 6 are sandwiched between the first extrusion device 20 and the first cushion device 22, and there is no gap between the adjacent surface plate carts 4. In this state, the platen carriage 4 moves to the downstream side in the transport direction by one pitch. Then, the platen carriage 4 placed at the downstream end position 10 of the first transport path 6 is positioned on the transfer carriage 42 placed at the first carry-out position 11 on the first traverser transport device 7. On the other hand, the transfer carriage 42 on the second traverser transfer device 9 is in an empty state.

  Next, the inverter motor 70 is driven to transmit the rotational torque to the drive sprocket 68 to rotate the drive shaft 50, so that the arm member 54 of the first traverser transport device 7 and the second traverser transport device 9 The arm member 76 is rotated simultaneously. The arm member 54 rotates to the second carry-in position 13 side, and the arm member 76 rotates to the second carry-out position 15 side. The transfer carriage 42 on which the surface plate carriage 4 is placed is positioned by the arm member 54 at the second carry-in position 13, and the empty transfer carriage 42 is positioned by the arm member 76 at the second carry-out position 15.

  At this time, in the first traverser transport device 7, on the rotation path of the arm member 54, for example, the start position confirmation proximity switch 78 is positioned at the horizontal position on the first unloading position 11 side, and the bottom dead center position of the arm member is set. Since the deceleration proximity switch 80 and the end position confirmation proximity switch 82 are arranged at the horizontal position on the second carry-in position 13 side, the rotation of the motor 70 with the inverter is controlled according to the rotational angle position of the arm member 54. Is done. Thereby, the surface plate carriage 4 placed on the transfer carriage 42 is quickly and safely transferred to the second carry-in position 13.

  The platen carriage 4 positioned at the second carry-in position 13 is sandwiched by the second extrusion device 24 and the second cushion device 26 together with the plurality of platen carriages 4 arranged in the second conveyance path 8. In the same manner as described above, 41 pitches of the platen carriage are conveyed to the upstream end 12 on the downstream side.

  According to the cart transport device 2 configured as described above, the rotational torque generated by the motor 70 with the inverter is simultaneously transmitted to both the first traverser transport device 7 and the second traverser transport device 9 by the drive shaft 50. Is done. In the first and second traverser conveying devices 7 and 9, the rotational torque is generated by the driving force converting means (slider crank mechanism) including the arm members 54 and 76, the slider 58, and the slider guide member 60. , The force is converted into a force for moving each of the vehicle-mounted mounts along the second transfer rail 62.

  In this way, the first traverser transport device 7 and the second traverser transport device 9 can move each transfer carriage 42 at a time by one motor 70 with an inverter. It is not necessary to provide a driving device for each traverser conveying device. Further, since the first traverser transport device 7 and the second treverser transport device 9 are driven to operate simultaneously and in the same operation by the motor 70 with an inverter, the operation steps of the traverser transport devices 7 and 9 are performed. The sensors 78, 80, and 82 to be detected need only be provided in one traverser conveyance device, and the control based on the signals of the sensors 78, 80, and 82 can be performed with a simple one. As a result, the equipment cost can be greatly reduced.

  Further, in any one of the traverser transfer devices 7 and 9, the surface plate carriage 4 is always placed on the transfer carriage 42 and moved from the transfer position of one transfer path to the transfer position of the other transfer path. Thus, there is no energy loss that the drive device is driven only to move the empty transfer carriage 42. As a result, the power cost can be reduced.

  Further, the drive shaft 50 extending between the first traverser transport device 7 and the second traverser transport device 9 causes the rotational torque of the motor 70 with an inverter to be simultaneously applied to the first traverser transport device 7 and the second traverser. This is transmitted to the transfer device 9. The transmitted rotational torque is converted into a force that linearly moves by a slider crank mechanism constituted by the arm members 54 and 76, the slider 58, and the slider guide member 60, and each transfer carriage 42 is moved to the first transfer rail 40 or the second transfer rail 40. It moves along the transfer rail 62. By such a simple mechanism, the rotational torque simultaneously transmitted to the first traverser transfer device 7 and the second traverser transfer device 9 is converted into a force in the direction in which the transfer carriage 42 moves to convert each transfer carriage 42. Can be moved.

In this way, the rotation of the motor 70 with the inverter is controlled according to the movement position of the bracket 142, and the transfer carriage 144 is moved after the placed surface carriage 4 is conveyed to the upstream end position 16 of the first conveyance path 4. , And quickly and accurately transferred to the second carry-out position 15 (or the third carry-out position 116).

Since the mechanism for moving the transfer carriage 144 of the second traverser transport device 112 is the same as that of the first traverser transport device 106, description thereof is omitted.
In this embodiment, since the other structure is the same as that of 1st Embodiment, the same code | symbol is provided and description is abbreviate | omitted.

Next, the operation of the cart transport apparatus 102 configured as described above will be described below.
In the first traverser transport device 106, as shown in FIG. 9, the empty transport cart 114 is positioned at the first carry-out position 11, and the platen cart 4 is placed in the second traverser transport device 112. The transfer carriage 144 is positioned at the first carry-in position 17. The process of transporting the platen cart 4 arranged in the first transport path 6 to the downstream side by one pitch of the cart using the first extrusion device 20 and the first cushion device 22 is the same as in the first embodiment. Description is omitted.

  The platen carriage 4 positioned at the first carry-in position 17 is conveyed to the upstream end position 16 of the first conveyance path 6 and the platen carriage 4 placed at the downstream end position 10 of the first conveyance path 6 is the first. Since the step of positioning at the carry-out position 11 using the first extrusion device 20 and the first cushion device 22 is the same as in the first embodiment, the description thereof is omitted.

  Then, the platen carriage 4 placed at the downstream end position 10 of the first conveyance path 6 is positioned on the transfer carriage 144 placed at the first carry-out position 11 by this conveyance step.

  Next, by driving the motor 70 with the inverter, the drive shaft 118 is rotated, and the drive shaft 118 rotates the drive shaft sprocket 134 provided on the drive shaft 118. The rotational torque of the drive shaft sprocket 134 is transmitted to the driven shaft sprocket 136 via the roller chain 140, and the two sprockets 134 and 136 rotate so that the transfer carriage 144 fixed to the roller chain 140 via the bracket 142 is Move from the first carry-out position 11 to the second carry-in position 13. At the same time, the empty transfer carriage 144 placed at the first carry-in position 17 of the second traverser transfer device 112 is transferred to the second carry-out position 15. Thus, by carrying out the driving of the motor 70 with the inverter once, the transport of the surface plate carriage 4 and the return of the empty transfer carriage 144 can be performed at the same time, thereby preventing energy loss and eliminating work waste. it can.

  Further, in the second traverser transport device 112 that moves simultaneously with the first traverser transport device 106, the first carry-in position confirmation proximity switch 145, the third carry-out position are placed on the movement path of the bracket 142. 116 is provided with a third carry-out position confirmation proximity switch 146, and the second carry-out position 15 is provided with a second carry-out position confirmation proximity switch 147 (these are the first carry-in position confirmation proximity switch 145 at the same time. (The unloading position confirmation proximity switch, the third unloading position confirmation proximity switch 146 also serves as the third unloading position confirmation proximity switch, and the second unloading position confirmation proximity switch 147 also serves as the second loading position confirmation proximity switch) Therefore, the rotation of the inverter-equipped motor 70 can be controlled according to the movement position of the bracket 142. Thereby, also in the 1st traverser conveyance apparatus 106, the surface plate truck 4 mounted in the transfer trolley 144 can be transferred quickly and safely.

  According to the cart conveying device configured as described above, the rotational torque of the motor 70 with the inverter is simultaneously increased by the drive shaft 118 extending between the first traverser conveying device 106 and the second traverser conveying device 112. It is transmitted to the first traverser transport device 106 and the second traverser transport device 112. The transmitted rotational torque is transmitted to a drive shaft sprocket 134 that is provided on one end side of the base frame body 38 of each of the first and second traverser transfer devices 106 and 112 and rotates in conjunction with the rotation of the drive shaft 118. It is done.

  The rotational torque has a driven shaft 138 parallel to the rotational shaft of the drive shaft sprocket 134, and is provided on the other end side of the base frame body 38 of the first and second traverser conveying devices 106 and 112, respectively. It is transmitted to the driven shaft sprocket 136 via the roller chain 140.

  The roller chain 140 is stretched between the drive shaft sprocket 134 and the driven shaft sprocket 136. When the drive shaft sprocket 134 rotates, the stretched roller chain 140 is moved between the drive shaft sprocket 134 and the driven shaft sprocket 136. It circulates on an endless track in which circular arc portions at both ends are formed by the outer peripheral portion. Since the transfer carriage 144 is connected to the roller chain 140 by a bracket 142 so as not to be relatively movable, the transfer carriage 144 moves along the first transfer rail 40 or the second transfer rail 62 by the rotation of the drive shaft sprocket 134, respectively. To do. By such a simple mechanism, the rotational torque simultaneously transmitted to the first traverser transport device 106 and the second traverser transport device 112 is converted into the first traverser transport device 106 and the second traverser transport device 112. Each transfer carriage 144 can be moved by converting it into a force in the direction of movement of the transfer carriage 144 provided respectively.

  Further, the rotational torque of the drive shaft 118 transmitted to the traverser conveying devices 106 and 112 on both sides moves the transfer carriage 144 in the moving direction by the combination of the sprockets 134 and 136 and the roller chain 140, and the transmitted force is Since no idle rotation occurs during transmission, the first traverser transport device 106 and the second traverser transport device 112 on both sides operate in synchronism accurately without causing energy loss. Therefore, for example, by arranging the proximity switches 145, 146, and 147 on the operation path of the second traverser transport device 112, the operation of the first traverser transport device 106 can be controlled with high accuracy. Further, it is not necessary to provide each proximity switch 145, 146, 147 for each traverser transfer device 106, 112, and the cost of equipment can be reduced.

  In addition, the first transport path 6, the second transport path 8, and the third transport path 104 are connected by the first traverser transport device 106 and the second traverser transport device 112. It is not limited, For example, it can implement to what is provided with four or more conveyance paths.

  Further, although the support wheels provided at both ends of the base frame body 38 are the drive shaft sprocket 134 and the driven shaft sprocket 136, the present invention is not limited thereto. For example, the support vehicles provided at both ends of the base frame body are Both may be driven shaft sprockets 136 provided at opposing positions, and the drive shaft sprocket 134 for rotating the roller chain 140 may be provided at a position shifted downward from the position at which the driven shaft sprocket 136 is provided.
