Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a continuous cleaning apparatus for press-processed parts (for example, 3.5-inch floppy shutters).

[Conventional technology]

Conventionally, parts processed by presses have oil attached to them, so they have been cleaned using an organic cleaning agent solution or steam, or a combination of these.

[Problem that the invention seeks to solve]

However, in conventional cleaning equipment, parts are grabbed one by one with a work holder and placed into a cleaning tank, resulting in poor cleaning efficiency and difficulty in increasing speed, and furthermore, continuous cleaning requires a long line. There was a problem.

Furthermore, since the work holder enters the cleaning tank together with the parts, there is a problem in that heat inside the cleaning tank is taken away and thermal efficiency is reduced.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a continuous cleaning device for pressed parts with good cleaning efficiency and thermal efficiency.

[Means for solving problems]

The continuous cleaning device for pressed parts according to the present invention, which achieves the above object, continuously applies heated cleaning liquid or cleaning steam to the guide groove of a floppy shutter, etc. to be cleaned, and presses parts that can be moved laterally. A continuous cleaning device for pressed parts that performs pre-cleaning and final cleaning by immersing and gradually feeding the parts, includes a cleaning guide for passing the pressed parts in parallel at predetermined intervals in a cleaning tank, and a cleaning guide disposed at the top of the cleaning tank. The conveyance guide, the lifting guide for transferring the press-worked parts between the cleaning guide and the conveyance guide, and the rear part of the press-worked parts placed on each of the above guides are simultaneously pushed to remove each part. The frame feeding means is configured to have a frame feeding means for pitch feeding.

[Effect]

The continuous cleaning device for pressed parts according to the present invention includes a cleaning guide arranged in a cleaning tank, a transport guide arranged at the upper part of the cleaning tank, and a transfer of parts of the transport guide and the cleaning guide. The device includes an elevating guide for moving each component, and a frame feeding means for moving each component frame by frame. Therefore, since the parts pass through the cleaning tank in parallel, a large number of parts can be processed.Furthermore, since no work holder is used, the only heat taken out of the cleaning tank is that given to the parts. This amount can be supplemented from outside.

The ultrasonic cleaning tank 11, the cooling tank 12, and the steam cleaning tank 13 are formed by dividing a large cleaning tank.
An ultrasonic transmitter 28 is disposed inside the steam cleaning tank 13, and a heater 29 is disposed at the bottom of the steam cleaning tank 13.

Inside the ultrasonic cleaning tank 11 and the steam cleaning tank 13, as shown in FIG. 3, a cleaning guide 14 having guide grooves into which 20 rows of floppy shutters 26 are fitted is arranged, and the front and rear portions thereof are provided with a cleaning guide 14. Lifting guides 21.24 are arranged.

This lifting guide 21 (lifting guide 22.23.24
．． 25) is shown in FIG. 5. As shown in FIG. The movably mounted receiver has the lifting guide 21 mounted on the member 33. Then, the above light is transmitted to member 3

Note that the support rods 38 to 40 and the support rod 44.
45 is attached to an elevating frame 51.52 which is supported by an upper cylinder 49.50 so as to be able to rise and fall freely,
The push rod 48 can be raised upwards if necessary.

As shown in FIG. 2, in the front part of the conveyance guide 17 in front of the ultrasonic cleaning tank 11, the floppy shutters 26 conveyed from the press are guided in series into a guide groove 53, and the floppy shutters 26 are connected in parallel. A pusher device 56 is provided to push the floppy shutters 26 arranged in parallel into the cleaning tank by means of a cylinder 55. At the outlet of the steam cleaning tank 13, A discharge guide 57 is provided to discharge the cleaned floppy shutter 26 to the outside.

Therefore, when using this continuous cleaning apparatus 10 for pressed parts, first place the floppy shutter 26, which is an example of the pressed part, on the conveyance guide 17, operate the frame feeding means 27, and move it up and down with the press rod 48. Place it on guide 21.

Next, the lifting guide 21 is lowered and connected to the cleaning guide 28. In this state, the cylinder 49 is extended to lower the elevating frame 51, and the pressing rod 48 that constitutes the frame feeding means
is inserted between the floppy shutters 26 and the frame feeding means 2

Next, the cylinder 49 is retracted and the lifting guide 21 is raised to move the floppy shutter 26 again. The floppy shutter 26 is taken in, lowered, and the above steps are repeated again to transfer the floppy shutter 26 to the cleaning guide 14. By repeating such a state, a large number of floppy shutters 26 are inserted vertically and horizontally into the ultrasonic cleaning tank 11 at predetermined intervals, and the ultrasonic transmitter 28 is activated to perform ultrasonic cleaning.

After this ultrasonic cleaning, the Fronby shutter 26 is placed on the lowered lifting guide 22, transferred to the transport guide 18 by the frame feeding means 27, moved to the lifting guide 23, and then lowered into the cooling tank 12. After being immersed and cooled, it is transferred again to the transport guide 18 and the ascending/lowering guide 24.

The lifting guide 24 is lowered, and the Fronby shutter 26 is immersed in the steam cleaning tank I3, and is cleaned by the steam adhering to the cooled floppy shutter 26. The frame is then gradually fed, transferred to the lifting guide 25, and then removed from the outside. It is guided to a transport guide 20 that communicates with the transport guide 20 . The above-mentioned transportation, cleaning, and lifting steps are performed continuously at regular intervals, so
A large amount of Fronby shutters 26 can be cleaned.

The cleaning liquid (usually trichloroethane, trichlorethylene, carbon tetrachloride) liquefied by the cooling pipe 58 on the side of the steam cleaning tank 13 is recovered, water-separated, and supplied to the cooling tank 12. The cleaning liquid that overflows enters the ultrasonic cleaning tank 11, and the cleaning liquid that overflows from the outlet at a predetermined height enters the steam cleaning tank 13 and is circulated throughout for use.

In the above embodiments, a Fronby shutter has been described, but any component can be applied as long as it can move in the guide groove by pressing.

〔Effect of the invention〕

As is clear from the above description, the continuous cleaning device for press-worked parts according to the present invention performs press work on each guide in which parallel guide grooves are formed, and performs cleaning while gradually advancing the pieces. This makes it possible to continuously wash large quantities of knobless machined parts.

In addition, since the pressed parts are directly conveyed and cleaned without using a work holder or the like, heat transfer can be minimized, thereby improving thermal efficiency.
