Description

[Detailed description of the invention] "Industrial application field" This invention uses one torque actuator and one hanging tool to change the direction of a lifting hand on a conveying device that moves along a rail. This invention relates to a lifting device for a conveying device that automatically repeats lifting, lowering, standing still, and transferring a basket handle in sequence.

``Prior Art'' Conventionally, an articulated robot has been used as a device for automatically raising, lowering, standing still, and laterally moving a basket in sequence without changing the direction of the basket hanging from the handle. However, the equipment of this robot is complicated and large, and it is inevitable that the cost will be high.

It is also conceivable to use two actuators to hold the basket handle from both sides.
However, when two actuators are used, there is a possibility that the movement between the two actuators will be erroneous, and that the articles stored in the basket will be shocked.

``Problems to be solved by the invention'' This invention does not use the above-mentioned articulated robot or two actuators, but uses one actuator and a special hook to support the car's lifting hand and attach it to the car. This allows the car to be repeatedly raised, lowered, left still, and moved using a simple device without applying any impact.

``Means for solving the problem'' This invention consists of a carrier that moves laterally along rails, an actuator that is attached to the carrier with the cylinder section facing vertically, and a drive source that reciprocates. A rotating rod to be rotated, a reciprocating rod rotating together with the rotating rod and reciprocating in the axial direction, and a reciprocating rod for reciprocating the reciprocating rod,
It consists of a port for injecting or discharging fluid pressure into the shaft support, and a hanging member fixed to the reciprocating rod and having hooks facing in opposite directions at both ends, and the hooks on both sides are connected to the cage. Hook the reciprocating rod onto the handle, pull up the reciprocating rod, stop the conveyor from moving along the rail, pull down the reciprocating rod, place the car in the inner bottom of the tank, stop it, pull down the reciprocating rod further, and place the hook on the car. Release the reciprocating rod from the lifting hand, turn the reciprocating rod about a quarter of a turn, then pull it up, stop the transport vehicle along the rail at the next car position, pull down the reciprocating rod, and rotate it about a quarter turn in the opposite direction. This is a suspension device for a transport device in which the reciprocating rod is pulled up after one rotation and the hook is hooked on the next car's handle, thereby moving the transport vehicle along the rail.

``Operation of the invention'' The present invention involves attaching one actuator to a rail carrier, reciprocating the actuator horizontally along the rail, rotating with the actuator's rotating rod, and reciprocating vertically. A reciprocating rod that is moved, and a reciprocating rod that is fixed to the tip of the reciprocating rod and has a hook part opened in opposite directions at both ends, the reciprocating rod is lowered and the hook part is released from the car's hanging hand, and the rotating rod is moved. After rotating the hook part so that it does not get in the way of the car's lifting hand, pull up the reciprocating rod and move the carrier along the rail, lower the reciprocating rod, and rotate the rotating rod to load the next car. It is constructed so that the reciprocating rod can be pulled up by hooking the hook onto the handle.

"Example" Reference numeral 1 denotes a rail that spans a transport vehicle 2 so as to move it in the lateral direction.
A motor and a pinion provided on the carrier, a rack provided on the rail, and a reciprocating movement are made along the rail. Reference numeral 3 denotes a mounting portion of the transport vehicle 2, and the cylinder portion 5 of the torque actuator 4 is mounted to this mounting portion with its axial direction facing vertically. Reference numeral 6 denotes a rotating rod which can be rotated by a required angle in the forward or reverse direction by a drive source 8 attached to the base head 7 of the cylinder portion 5. In this embodiment, a motor is used which is wired to rotate approximately one quarter in forward and reverse directions. Reference numeral 9 denotes a reciprocating rod which rotates coaxially with the rotary rod 6 and is reciprocated within the cylinder portion 5 by pistons 10, 10'. 11 and 12 are pressure fluid entry ports and needle valves provided in the base head 7 of the cylinder portion 5; 13 and 14 are the cylinder portion 5;
16 is a hook attached to the tip of the reciprocating rod 9; 17 and 17' are L-shaped pieces connected to both ends of the hook 16, respectively; 18,1
Reference numeral 8' denotes hook portions formed on these L-shaped pieces so that the bending directions are opposite to each other. Reference numeral 20 denotes a hanging hand horizontally suspended at the upper end of legs 21 and 21' protruding from both sides of the car 19;
22, 22', 22''... are ultrasonic cleaning tanks arranged in the longitudinal direction of the rail 1.

To explain the operation of the present invention, as shown in FIG. , and pressure fluid is injected from port 13. Then, the lower surface of the piston 10' rises under the pressure of the pressure fluid, and the piston 10
hits the base head 7 of the cylinder part and stops.
Therefore, the cage 19 is lifted above the ultrasonic cleaning tank 22. Next, the motor (not shown) of the transport vehicle 2 is driven to rotate the pinion, and the transport vehicle 2 is moved in the direction of the arrow in FIG. 3 by the rack of the rail 1. When the car 19 moves to just above the next ultrasonic cleaning tank 22', the rotation of the motor of the transport vehicle 2 is stopped, and the injection of pressure fluid into the port 13 is stopped.
Inject pressure fluid into 1. Therefore, the upper surface of the piston 10 is pressurized, and the pressure applied to the lower surface of the piston 10' is released to the outside from the needle valve 14, and the reciprocating rod 9 is lowered. When the cage 19 is placed on the inner bottom of the ultrasonic cleaning tank 22' and the reciprocating piston 9 is further lowered, the hooks 18 and 18' of the hook 16 are removed.
Since it will come off from the handle 20, at that time port 11
The injection of pressure fluid into the piston 10 is stopped, and the lower end of the piston 10 is brought into contact with the tip head 15. Next, the drive source 8 is activated to rotate the rotary rod 6 approximately one-fourth of a turn in the forward direction. Then, the hook portions 18 and 18' of the hook 16 are released from the handle 20 of the car 19, as shown by the movement line in FIG. 1, and become free.

Next, pressure fluid is injected from the port 13 to raise the reciprocating rod 9 together with the piston 10', causing the piston 10 to stop against the base head 7. Next, the motor of the conveyance vehicle 2 is driven in the opposite direction to that described above to stop the conveyance vehicle 2 directly above the ultrasonic cleaning tank 22, and pressurized fluid is injected into the port 11. Therefore piston 1
The upper surface of the car 0 is pressurized, and the pressure applied to the lower surface of the piston 10' is released to the outside from the needle valve 14, and the reciprocating rod 9 descends, lifting the next car 19 housed in the ultrasonic cleaning tank 22. Hook portions 18 and 18' of the hook 16 are located below the hand 20. Next, the drive source 8 is operated in the opposite manner to the above to rotate the rotating rod 6.
Turn it about a quarter turn in the opposite direction. Then hook 1
The hooks 18 and 18' of No. 6 are approximately 4
Since the position has been rotated by one-quarter of a rotation, in this state, if pressure fluid pressure is applied to the lower surface of the piston 10' from the port 13, the reciprocating rod 9 will rise, and the hooks 18 and 18' of the hook 16 will be connected to the lifting hand of the car 19. 20 and lift it up. By repeating the above operations, the baskets 19 are sequentially placed in the ultrasonic cleaning tanks 22, 22', 22'', etc., and the cleaning operation is performed for the required time.Hook 1
The vertical movement and horizontal movement of 6 can also be performed automatically via a storage device. In the above embodiment, a case where a workpiece is cleaned in an ultrasonic cleaning tank has been described, but the present invention can be widely used for workpiece plating, cleaning, and other processing operations of a belt conveyor system.

"Effects of the invention" As described above, the present invention allows the transport vehicle to reciprocate along the rail, and the reciprocating rod can be vertically moved and rotated by the torque actuator provided on the transport vehicle. Can be done. In addition, by attaching a hook to the tip of the reciprocating rod that has hooks on both ends facing in opposite directions, the car can be moved up and down by rotating the reciprocating rod and hooking the hook on the car handle. Since a single actuator can perform the operations of horizontally moving, releasing the hook from the car's hanging hand, and leaving the car still, there is no need to use a complicated multi-jointed robot or multi-headed clamping tool. Therefore, there are effects such as safe and easy operation without investing a large amount of money into the equipment.
