Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a cleaning device, which is used to clean objects that are covered with dirt such as chips, burrs, and sludge that are separated from objects to be cleaned during cleaning operations. The purpose is to prevent the items to be washed from being recontaminated and to enable cleaning work to be performed using clean cleaning liquid at all times.

Conventional Technology Conventionally, dirt such as chips, burrs, and sludge separated from the object to be cleaned during cleaning work falls to the bottom of the cleaning tank or remains suspended in the cleaning solution. The object to be cleaned is cleaned using this dirty cleaning liquid. In addition, in order to perform highly precise cleaning, cleaning liquid is stored in a number of cleaning tanks, and the object to be cleaned is sequentially immersed in the cleaning tanks to perform the cleaning work. However, this method not only required a large amount of cleaning liquid and increased the size of the equipment, but also the cleaning liquid became contaminated once the object to be cleaned was immersed, making reliable precision cleaning difficult. .

Problems to be Solved by the Invention The present invention attempts to solve the above-mentioned problems. The purpose is to prevent items from being recontaminated and to enable precision cleaning using a small amount of clean cleaning fluid.

Means for Solving the Problems The present invention solves the above problems by:
A storage body for objects to be cleaned is connected to an up-and-down movement means so that it can be moved up and down in the cleaning tank, and a filter is installed at least at the upper end of this storage body to prevent the flow of dirt but allow the cleaning solution to flow. The lower bottom wall or side wall can be opened so that when the container is removed from the cleaning liquid, the lower bottom wall or side wall can be opened and the internal cleaning liquid and dirt can be discharged into the cleaning tank, and when the storage object is inserted into the cleaning liquid. , the opening can be closed and the cleaning liquid can be introduced into the storage body through a filter.

In addition, to open the storage body, one end of the lower bottom wall is pivoted to the storage body with a support shaft so that it can be opened and closed, and this lower bottom wall is constantly biased in the closing direction by a spring, and the restoring force of the spring is applied. The lower bottom wall may be pushed open by the weight of the cleaning liquid inside the housing when the housing is separated from the cleaning liquid.

In addition, to open the storage body, one end of the side wall is pivoted to the storage body with a support shaft so that it can be opened and closed, and this side wall is constantly biased in the closing direction by a spring, and the restoring force of the spring is applied to the storage body. The cleaning liquid inside the container when separated from the cleaning liquid may be such that the side wall can be pushed open by the weight of the cleaning liquid.

Further, the storage body may be formed in the shape of a liquid-tight box using a metal plate, and a filter may be partially provided at the upper end.

Function Since the present invention is configured as described above, in order to perform the cleaning work of the object to be cleaned, the object to be cleaned is stored in the storage body from the lower bottom wall or the side wall which can be opened, and the object to be cleaned is moved to the vertical movement means. Then insert the container into the cleaning solution. In this insertion, since the storage body has a filter installed at least at its upper end, the cleaning liquid flows into the storage body through the filter and is used to clean the object to be cleaned. Through this cleaning process,
Filth such as chips, burrs, and sludge are separated from the object to be cleaned. As a result of this separation of dirt, the cleaning liquid inside the container becomes contaminated and re-adheres to the object to be cleaned. When this state is reached, operate the vertical movement means,
The storage body is removed from the cleaning liquid and positioned above the liquid level. Since the lower bottom wall or side wall of the container can be opened, when the lower bottom wall or side wall is separated from the cleaning liquid, it is pushed open by the weight of the cleaning liquid located inside the storage body, and the bottom wall or side wall is pushed open and released together with the cleaning liquid. The waste separated from the objects is discharged into the cleaning tank. This discharge releases the pressing force on the bottom wall or side wall, so either apply a biasing force in the closing direction to the bottom wall or side wall with a spring or the like, or use appropriate mechanical or electrical work to open the opening. can be closed. When the housing is inserted into the cleaning liquid again after the opening of the housing is closed, the cleaned cleaning liquid flows into the housing through the filter that prevents the flow of dirt but allows the cleaning liquid to flow.
After cleaning the object to be cleaned again with this purified cleaning liquid, the above-mentioned dirt and cleaning liquid are discharged, and by repeating this process several times, it is possible to clean the object with the cleaned cleaning liquid. This enables highly precise cleaning.

Embodiment An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes a vertical movement means, and a suitable drive mechanism 3 such as an air cylinder, an oil cylinder, or a chain drive mechanism is mounted on the outer surface of the cleaning tank 2. and a connecting rod 4 located in the cleaning tank 2 parallel to this drive mechanism 3.
It protrudes from the cleaning tank 2 to the outside, and the upper end of this protrusion is connected to the drive mechanism 3 by a connecting plate 5. Further, a support arm 6 protrudes from the lower end of the connecting rod 4 of the vertical movement means 1, and by engaging the support arm 6 with an engagement flange 8 protruding from the side surface of the storage body 7, the object to be cleaned 10 can be cleaned. The stored storage body 7 can be moved up and down.

A filter 13 such as a microfilter that blocks the flow of dirt 11 but allows the cleaning liquid 12 to flow is installed at least at the upper end of the storage body 7, and the storage body 7 can be opened. Further, the filter 13 may be provided not only at the upper end of the storage body 7, but also on the side wall 14 and the bottom wall 15 together with the upper end, or the storage body 7 may be formed into a liquid-tight box shape with a metal plate, and the filter 13 may be provided at the upper end. 13 may be provided. The opening of the storage body 7 is achieved by dividing the lower bottom wall 15 into two parts from the center, and supporting one end of each part on the storage body 7 with a support shaft 16 so as to be openable and closable. A spring 18 biased in the pulling direction is stretched between the mounting piece 17 for the object to be cleaned 10 in the storage body 7, and the lower bottom wall 15 is constantly biased in the closing direction. There is. In addition, the restoring force of this spring 18 is determined by the restoring force of the storage body 7 when the storage body 7 is separated from the cleaning liquid 12.
The weight of the cleaning liquid 12 inside is such that the lower bottom wall 15 can be pushed open.

Furthermore, opening the storage body 7 by opening the lower bottom wall 15 is preferable in terms of the effect of discharging the dirt 11, but if the upper space 19 of the cleaning tank 2 cannot be made high, one end of the side wall 14 may be opened. The side wall 14 may be formed to be openable by being pivotally supported on the body 7 so as to be openable and closable. Other points are similar to the above embodiments.

In the structure as described above, in order to perform cleaning work on the object 10 to be cleaned, the lower bottom wall 15 or the side wall 14 which can be opened is opened, and the object 10 to be cleaned is stored in the storage body 7.
