Description

A cart having a motor driven system

The present invention relates to a trolley having a motor driving system, and more particularly, has a motor driving system which is operated before, after, and under a motor and a sensor to improve productivity and prevent safety accidents. It's about a bogie.

In general, manufacturing lines that manufacture or produce a finished product through various processes according to its characteristics usually assemble sequential parts through sequential steps. It transfers to each process step by using a transfer means such as a transfer or a trolley.

In particular, in the case of parts to be heat-treated, in order to increase productivity or efficiency, several parts are stacked on a pallet and then placed on a trolley and transferred to a heat treatment apparatus. The trolley 1 for this purpose is shown in FIG. And a lower end to support the workpiece loading part 2, which consists of a circular roller 2a which is freely rotated to facilitate the transfer to the work table A, on which a pallet (not shown) loaded with The support frame 4 and the support frame 4 are provided with a base member 3, which is provided with an oil container B for collecting the oil falling from the work-loading part 2 while supporting the base member 3; It is mounted to the bottom of the) consists of a moving member (5) consisting of wheels connected via a shaft to move along the rail of the floor.

Therefore, the worker places the pallet on which the parts to be heat-treated are placed on the work loading part 2 of the trolley 1 by using a crane or a host, and then grasps the handle and pushes the movable member 5 along the work line. After moving on the rail to approach the work table A pre-installed in the heat treatment furnace part, the operator pushes the pallet mounted on the work-loading part 2 to seat the pallet on the work table A.

Alternatively, the pallet on which the heat-treated parts are loaded is placed on the trolley 1 and moved to the assembly line.

In this way, the trolley 1 used to convey the heavy pallet loaded with the parts is simply placed on the pallet on the workpiece stack 2, and the worker pushes it with his own force to the work table A, and then with the operator's own force. As the pallet is pushed onto the workbench (A), it not only demands excessive labor intensity from the operator but also causes safety accidents such as burns due to the high temperature remaining when moving the heat-treated parts or injury due to the carelessness of the operator. There is always the problem of danger.

Therefore, the present invention was invented to solve the problems as described above, by using a motor operated by a simple operation to move the truck before and after to reduce the labor force of the worker as well as the movement of the pallet is operated by the motor By mechanical means, it is possible to completely eliminate the risk of burns caused by heat-treated parts to prevent safety accidents and improve labor productivity.

Technical means of the present invention for achieving the above object is a work-loading portion having a roller and a sensor motor driven by a trolley for conveying pallets loaded parts, cylinders and stoppers to selectively tilt the work-loading portion And a base member having a sensor, a support frame having a power transmission means while supporting the base member, and a moving member provided below the support frame and rotated by the power transmission means and moved along the rail. The power transmission means is composed of a first power unit for transmitting power to the workpiece loading unit, a second power unit for transmitting power to the moving member, and a control unit for controlling the first and second power units.

The moving member 9d is provided with a roller to move along the horizontal frame 9c as well as a built-in cable 9e. Hereinafter, the operation of the present invention will be described in detail with reference to the accompanying drawings.

First, the worker raises the pallet on which the parts to be heat-treated are loaded onto the work loading part 2 of the trolley 1 using a hoist or the like, and then advances the adjuster 8b of the control part 8 constituting the power transmission means. When the reverse button is operated, the power transmission unit 7b of the motor 7c of the second power unit 7 rotates to move the moving member provided with the power transmission unit 5a through the power transmission member 7a ( 5) is advanced or reversed.

Subsequently, the movable member 5 rotated by the second power unit 7 is moved along the rail so that the sensors 3b provided on the left and right sides of the base member 3 are left and right worktables A and A '. ), The contact of this sensor (3b) is continued, that is, the contact of the limit switch is connected to cut off the power connection contact in the control box (8a) to cut off the power of the motor (7c) moving member (5) The rotation of the stops and the trolley 1 is stopped.

Here, the cable (9e) provided in the guide frame (9) for supplying power to the trolley is moved forward or backward by the moving member (9d) coupled to the horizontal frame (9c) in accordance with the movement of the trolley. After the trolley 1 is moved to the work bench as described above, the operator operates the operation button of the adjuster 8b to move the pallet D to the left work platform A. When the cylinder 3c 'is raised to incline the workpiece loading portion 2, the limit switch, which is the sensor 2e located on the lower surface of the inclined workpiece loading portion 2, is brought into contact with the contact member 3d1 of the left stopper 3d. Upon contact, the right cylinder 3c 'stops operating and power is supplied to the first power unit 6 according to the circuit of the control box 8a.

Subsequently, the second roller of the workpiece loading part 2 connected to the power transmission member 6a coupled to the power transmission part 6b by rotating the motor 6c of the first power supply part 6 supplied with power. (2a2) and the first roller (2a1) are rotated, the pallet (D) is moved in the direction of the arrow by the first and second rollers (2a1, 2a2) that is rotated to be transferred to the left work platform (A).

Figure 4 I shows the operating state using the right workbench (A '), the operation process or method is omitted because it is the same as described above except that changed from the left side to the right side.

Next, the process and operation for moving the pallet loaded with heat-treated parts to the trolley 1 and moving it to the work line will be described. A pallet with a high temperature remaining is provided along the ceiling of the work line to lift an object. When placed on the work-loading unit 2 using a general moving device), the operator operates the regulator 8b to operate the motor 7c of the second power unit 7 via the power transmission member 7a. The moving member 5 moves forward or backward to the work benches A and A '.

When the trolley 1 is moved to the work table as described above, the rotation of the movable member 5 is stopped by the sensor 3b as described above, and then the operator operates the operation button of the adjuster 8b to the left of the inclined operation means. After raising the side cylinder 3c or the right cylinder 3c ', power is supplied to the first power unit 6 via the sensor 2e which is in contact with the left stopper 3d or the right stopper 3d'. Therefore, the pallet D is conveyed to the left work bench A or the right work bench A 'by the 1st and 2nd rollers 2a1 and 2a2 which the workpiece loading part 2 rotates.

As described above, according to the present invention, not only the operation and the operation are performed by the operation buttons and the signal of the sensor, but also the operation is easy, and the front, rear, up, high, and rotational movements of the truck use the power of the motor. As a result, the labor force of the worker is not only reduced, but also it is possible to prevent safety accidents such as burns due to heat-treated parts and physical injuries due to excessive weight and to improve labor productivity.
