Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shower-type cleaning device suitable for cleaning a large amount of workpieces (objects to be cleaned) having a complicated three-dimensional shape such as a container and flat-plate workpieces uniformly and precisely. It is a thing.

[0002]

2. Description of the Related Art A general cleaning apparatus employs various cleaning methods such as shower type, ultrasonic type, bubbling type, etc. according to its purpose. The shower-type cleaning device is particularly excellent for large-scale cleaning.

However, in this shower type cleaning apparatus, if the shape and configuration of the work is plate-like or close to it, the shower jets from both sides of the work uniformly hit the work at an effective angle close to a right angle. Although effective cleaning is possible, the shape of the work is a three-dimensional structure with inner and outer surfaces such as a container, and the cleaning surface is combined in a vertical direction other than the horizontal direction or a cleaning surface close to this. In this case, the cleaning surface is parallel to the spray direction, and the kinetic energy of the spray of the shower cannot be uniformly received at an effective angle, resulting in uneven cleaning.

A known conventional technique for the above-mentioned defects will be described, for example, by Japanese Utility Model Laid-Open No. 62-30767, in which a container-shaped work is turned down so that the opening is downward and the nozzle group is not in the vertical direction with respect to the work. It is also provided in the direction of both side surfaces, and is composed of four groups of nozzles as a whole, and each nozzle group is configured to reciprocate by swinging, so that the work can pass the work through the nozzle group. An apparatus for cleaning a container-shaped work has been considered.

Further, as another conventional publicly known technique for the same purpose as the above publicly known example, there is Japanese Utility Model Laid-Open No. 1-88785.
A device for cleaning a three-dimensional work by configuring a group of nozzles to rotate has been considered.

Further, the nozzle type applied to this type of cleaning apparatus is a hollow cone type nozzle in which the shower spraying direction is wide and radial as shown in FIG. 3 for the purpose of uniformly applying the shower spraying direction to the cleaning surface. It has been a conventional technique to apply a nozzle 14 having a conical shape or a full-cone nozzle 15 having a conical shape to widen the spraying direction of the shower so that the cleaning surface is not parallel to the spraying direction.

[0007]

Among the above-mentioned conventional techniques, the above-mentioned Japanese Utility Model Laid-Open No. 62-30767 discloses that the upper and lower horizontal surfaces of a container-shaped workpiece are cleaned and the vertical surface of the nozzle in the swinging direction. Although it has a cleaning effect, the main jet direction of the shower is parallel to the cleaning surface with respect to the vertical plane of the movement direction of the work, and the kinetic energy of the shower liquid is not suitable for the separation and cleaning of contaminants. There is a problem that it does not function effectively and a uniform cleaning effect cannot be obtained. In addition, the number of nozzle groups on the top and bottom and the four groups on both sides are increased.
Therefore, a large number of nozzles are required, and since it is necessary to make each nozzle group reciprocate by swinging, the structure of this mechanic is complicated, the power of the motor is required, and the manufacturing cost of the equipment is expensive and large. In addition, there are problems such as wear life of the sliding portion and failure thereof.

In addition, among the above-mentioned conventional techniques, the below-mentioned actual Kaihei 1
-88785 discloses the above-mentioned known example (Saikai Sho 62-3).
No. 0767), and since the nozzle 4 group is further rotated, the nozzles at the center of rotation of the nozzles and the nozzles at the outer periphery have different peripheral velocities, which causes uneven cleaning. There was a problem.

Further, since the hollow cone type nozzle 14 having a radial jetting direction and the full cone type nozzle 15 having a conical jetting direction jets over a wide area, the shower flow velocity is low and the flow rate per unit area is small. Therefore, there is a problem that the kinetic energy of the washing liquid per unit area becomes low, and even if it is effective for uniformizing the jetting energy of the washing liquid of the shower, it becomes weak and the entire washing function becomes insufficient.

In particular, the washing of a work in which solid contaminants are strongly adsorbed requires a peeling action due to the strong kinetic energy of the shower, and the conventional technique cannot wash with a small shower pump. Therefore, it is necessary to increase the size and pressure of the shower pump, which causes problems such as increase in equipment cost and power consumption.

The work is set on the net in the washing room,
In a shower-type cleaning device for cleaning by showering a cleaning liquid, a plurality of nozzle tubes are arranged above a work in a direction parallel to a net, and a plurality of nozzles for fan-shaped ejection are attached to each of the nozzle tubes.
