Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic cleaning apparatus in which a space for the cleaning apparatus is reduced as much as possible in a transfer machine structure employed in the automatic cleaning apparatus.

[0002]

2. Description of the Related Art FIG. 3 shows a conventional cleaning apparatus having a linear drive type transfer machine corresponding to a cleaning tank arranged on a straight line used for cleaning machined parts and the like.

[0003] As shown in the figure, a carry-in waiting cleaning part 22 set on a carry-in pallet 21 is carried into the carry-in tank 1 by a carry-in robot 42.

Next, the linear transfer drive unit 44 for transferring the cleaning component 22 to each of the cleaning tanks 2 to 9 is transferred to the preceding cleaning tank by the interlocking of the transfer arms 14 integrated at nine locations. 9 to 9 are sequentially processed and conveyed, and when they reach the unloading tank 10, the unloading robot 43 causes the cleaning parts 2.
2 is taken out and placed on the carry-out pallet 20 to complete the cleaning process. According to the present apparatus, the transfer mechanism is a linear drive transfer device parallel to the tank in accordance with the processing tank on the straight line.

Therefore, the transport drive mechanism becomes longer,
Further, the transfer arm protrudes to the tank side, so that it becomes cantilevered and is in a state of poor balance. Further, when the washing tanks are arranged in one row and the number of tanks increases, a very long floor space is required.

[0006]

In the case of a cleaning apparatus comprising a large number of cleaning tanks, when the cleaning tanks are arranged on a circumference to form a small space tank arrangement, these tanks are arranged on the circumference. Accordingly, a transport structure capable of moving and transporting the cleaning parts with high rigidity and high stability is achieved.

[0007]

Means for Solving the Problems A transporter corresponding to an upper circumferential tank arrangement is provided, a transporter support plate for supporting the transporter is provided, and these can be moved up and down by four sliding shafts. In the vicinity of the outer periphery of the disk, there are nine radially extending transfer arms, which suspend the cleaning components, but provide rails that support the load, and maintain the rigidity of the arms. An arc-shaped partial gear drive unit that performs circumferential movement between the front and rear tanks in a circumferential arrangement is provided, and its position is made closer to the outer periphery to improve stopping accuracy.

[0008]

1 and 2 are a plan view of a transfer machine corresponding to a circumferentially arranged cleaning tank according to the present invention, and a cross-sectional view of a transfer mechanism between the tanks and a lifting drive mechanism of the transfer machine. Show.

According to FIG. 1, each of the cleaning tanks 1 to 10 is arranged on a circumference on the apparatus gantry 11 in the processing order, and a transfer arm 14 extends radially from the center of the circumference to the upper part of each tank.
The on-peripheral operation of the transfer arm 14 includes a motor 15 for moving between tanks,
The arc-shaped partial gear 19 reciprocates on the inter-tank moving rail 12. In addition, the vertical movement is performed by the four elevating sliding parts 27 via the carrier support plate 28 as a whole of the above operation mechanism.

The transfer of the cleaning parts to the carry-in tank 1 and the carry-out tank 10 is performed by a carry-in pallet 21 on which the wash parts are set.
Is carried out by the carry-in / out robot 23 which lifts and moves the cleaning parts between the pallet tanks and the carry-out pallet 20 for receiving the processing-completed parts.

The processing operation of the above-described cleaning apparatus is shown in FIG.
Thus, the cleaning component 22 set on the loading pallet 21 is lifted by the component chuck 26 of the loading / unloading robot 23 and transferred to the loading tub 1. Loading / unloading robot 23
Is in standby, the parts suspending arm 31 of the transporter shown in FIG.
Is lowered from the upper part along four lifting sliding parts 27 by the operation of the lifting drive unit 41, the lifting feed nut 38, and the lifting feed screw 39, and further, the motor 15 between the tanks, the worm gear 16, the worm wheel 17, By means of the gear 18 and the arcuate partial gear 19, the transfer arm 14, the single moving roller 13 and the suspended load supporting roller 29 are connected to the inter-tank moving rail 1.
2. The inside of the tank and between the tanks are moved along the suspension load support rail 34, and the cleaning part 22 in the carry-in tank is transferred to the next tank, the coarse ultrasonic A tank 2.

Since the transfer arms 14 are formed as a single unit, the transfer arms 14 are simultaneously moved in all the tanks. In addition, the transport component hanging arm 31 having the cleaning component 22 transferred to the front tank always returns to the rear tank and waits, and is transferred to the next tank every time the processing is completed. And the process is completed.

An advantage of the circumferentially-operated transfer machine structure employed in the present apparatus is that a cleaning apparatus with a small space can be achieved.

[0014]

As described above, according to the automatic cleaning apparatus of the present invention, the following effects can be achieved.

(1) A device with a small space is possible.

(2) The inter-tank moving drive mechanism is supported by four shafts in the upper part of the tank, and has good balance and rigidity.

(3) Two robots for loading and unloading are 1
Can be used as a stand.
