Description

DETAILED DESCRIPTION OF THE INVENTION TECHNICAL FIELD The present invention relates to an automatic cleaning device for metal workpieces to which oil, grease, chips, scale, etc. are adhered, in particular.

Conventional technology Conventionally, there are various types of automatic cleaning equipment, such as those using dipping, high-frequency cleaning, brush cleaning, and spraying. Spray cleaning is known. This jet spray cleaning is a method in which cleaning liquid is jetted out from micropores at high pressure, and the object is cleaned using the impact force of the jetting and the original cleaning power of the cleaning liquid. This method can clean intricately shaped items at high speed, down to the smallest detail, but when cleaning a cylinder block as shown in Figure 1, (a) (b) Dirt in drill hole 1 and tap hole 2, which has differences in the rate of removal of dirt and spots,
It is even more difficult to remove, and the remaining amount of chips is 200 to 500.
mg, and even high-performance ones can range from 80 to 100 mg.
(c) Since the nozzle position is fixed, there are problems such as differences in the cleaning effect depending on the size of the object to be cleaned, especially the size of the object.

Purpose The present invention enables cleaning even when the shape and dimensions of the cleaning object change.
To make it possible to always accurately and efficiently wash an object without the need for change of setup and regardless of the position of a hole provided in the object to be cleaned.

Configuration The present invention has a moving roller on the upper surface, a fixed clamp bar is provided at one end of the roller, and
The other end is equipped with a trolley equipped with a movable clamp bar that moves by the action of a cylinder, and is a chamber for carrying in and out the trolley, which is equipped with a stopper at a predetermined position, and a subsequent intermediate processing. One of the intermediate processing chambers is equipped with a side cleaning nozzle and a top cleaning nozzle that moves up and down according to the height of the object to be washed, and a first moving chamber having a positioning device for the object to be washed is connected to the end thereof, In addition, a side cleaning nozzle and a bottom cleaning nozzle are installed in one of the remaining right angles of the intermediate processing chamber, and a second moving chamber is provided beyond that, and the cleaning items on the trolley are gripped from above and transported back and forth. This is an automatic cleaning device characterized in that an internal conveying device is provided across an intermediate processing chamber and a second transfer chamber.

The present invention will be explained in detail below based on the drawings.

FIG. 2 is a plan view showing the configuration of an embodiment of the present invention, in which A is a pre-process, B is a cart loading chamber, C is an intermediate processing chamber, D is a first transfer chamber, and E is a second transfer chamber. .

The trolley 3 on which washed items are loaded and transported is shown in Figures 3 and 4.
Use the format shown in the figure. That is, it has a roller 23 on the upper surface, a fixed clamp bar 24 at one end of the roller 23, and a movable clamp bar 15 that moves under the action of a cylinder 25 at the other end. Further, 16 is a wheel, and 17 is a chain bracket, which is connected to a chain conveyor T disposed under the floor across the trolley loading/unloading chamber B, intermediate processing chamber C, and first transfer chamber D. It's starting to move.

The cleaning object M that has gone through the pre-process A is placed on the trolley 3, and the fixed clamp bar 24 and the movable clamp bar 1
5, the cart is carried into the cart loading chamber B, and is stopped at a fixed position by a stopper 4. This fixed position is such that the end surface (the right end in FIG. 2) of the object to be cleaned passes through a position close to a cleaning nozzle case 5 installed at the entrance of the first moving chamber D, which will be described later.

Next, the trolley 3 is attached to the attached chain bracket 17.
is connected to a chain conveyor T running under the floor, and as the chain conveyor T moves, it is sent to an intermediate processing chamber C and then to a first transfer chamber D. At the entrance of the first moving chamber D, side cleaning nozzle cases 5 and 6 and a top cleaning nozzle case 7 are installed. These cleaning nozzle cases are arranged as shown in FIG. 5, and each is provided with nozzle holes 8 arranged in three rows in a staggered manner at intervals of, for example, 5 mm on the surface facing the object to be cleaned. By doing so, the cleaning liquid can be sprayed almost straight into the pores at any position on the surface of the cleaning object M moving in front of the nozzle hole 8.

The object to be washed that has entered the first moving chamber D is moved on the cart 3 by positioning devices 9 and 10.
That is, the cleaning object M is positioned by the positioning devices 9 and 10.
By sandwiching the positioning device 9 and pushing out the positioning device 9,
The left end surface of the object to be cleaned in FIG. 2 is moved so as to pass through a position close to the cleaning nozzle case 6.
Then, the trolley 3 is moved again toward the intermediate processing chamber C by running the chain conveyor T in the reverse direction, passes through the side cleaning nozzle cases 5 and 6 and the top cleaning nozzle case 7, and is cleaned again. Ru. While the object to be cleaned M moves back and forth between these cleaning nozzle cases, the upper surface cleaning nozzle case 7 moves up and down according to the height of the object to be cleaned, and sprays cleaning liquid from a position close to the upper surface of the object to be cleaned.

Next, from the intermediate processing chamber C, the object to be cleaned M is grasped from above using a suitable internal transport device 11 provided on the ceiling and moved toward the second transfer chamber E. FIG. 6 shows a perspective view of an example of the internal conveyance device 11, which has a fixed clamp bar 20 at one end of an inner rail conveyance vehicle 19 conveyed by the conveyance cylinder 18.
Opposed thereto is a clamp bar 21 designed to be moved by a clamp cylinder 22. The fixed clamp bar 20 and the clamp bar 21 clamp the object M to be washed from above, and transport it to the second moving chamber E by the transport cylinder 18. Side cleaning nozzle cases 12, 13 and a bottom cleaning nozzle case 14 are provided at the entrance of the second moving chamber E, and clean both sides and the bottom of the object M passing therethrough. The side cleaning nozzle cases 12 and 13 may be movable according to the dimensions of the object M to be cleaned, or by changing the reciprocating locus of the internal conveyance device 11, the side cleaning nozzle cases 12 and 13 can be moved on one side at a time. It may be moved closer to the case.

The washed items coming out of the second transfer chamber are returned to the intermediate processing chamber C.
It is placed on a trolley waiting in the interior, and after passing through the trolley loading room B, the entire trolley is sent to process F. At this time, the stopper 4 is appropriately retracted so as not to interfere with the unloading of the cart 3.

In the above device, intermediate processing room C and trolley loading room B
It may be common to Moreover, air blowing may be performed instead of jetting out the cleaning liquid.

Effects The present invention is as described above, and since the cleaning object M is cleaned using the side cleaning nozzle cases 5, 6, 12, 13, the top cleaning nozzle case 7, and the bottom cleaning nozzle case 14, the cleaning object M The entire surface of the top, bottom, front, back, left, and right sides of the machine can be cleaned evenly, and each surface is cleaned very close to each cleaning nozzle, making it possible to target and thoroughly clean even minute holes or blind holes. be able to.

According to this device, as mentioned above, the remaining amount of chips, which previously was at least 80 to 100 mg, can be reduced to 80 mg.
I was able to do the following.

In addition, it is possible to easily handle the cleaning items by moving them appropriately depending on the shape and size of the cleaning items, so you can change the cleaning equipment according to the size of the cleaning items or attach accessories. There is no need to use any equipment, eliminating the time and equipment required for changeovers, and significantly reducing cleaning costs.
