BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a parts washing device for a washing machine, which is suitable for washing a die such as a die used in a tablet machine and other parts.

[0002]

2. Description of the Related Art Generally, stains on a mold of a tablet machine and various parts are cleaned and removed manually by an operator.

However, since such a cleaning operation requires a lot of manpower, it is difficult to deal with the situation when manpower is insufficient. Therefore, recently, a cleaning device for automatically cleaning the punch has been developed. This cleaning device
A net-like holding member is provided in the box opened up and down, and a large number of punches are held by the holding member in a posture in which the punch surfaces face upward. Then, by moving this box in a certain direction by a roller conveyor and passing it under a nozzle for jetting hot water downward, the dirt attached to each punch is washed away.

[0004]

However, in such a device, hot water is sprayed only from a limited direction to the pestle to be cleaned, so that an area where stains cannot be sufficiently removed easily occurs. . Further, in such an apparatus, since the cleaning process is transferred to the drying process while the hot water is still accumulated on the upward facing punch surface, impurities contained in the hot water are concentrated and adhere to the punch surface. Easy to invite. Further, there is a problem that it is difficult to sufficiently remove the oil content by washing only with warm water.

An object of the present invention is to eliminate such inconvenience.

[0006]

In order to achieve the above object, the present invention takes the following measures. That is, a parts washing device for a tablet machine according to the present invention includes a gantry that can be rotated in a plane, a part holding unit that is disposed on the gantry and holds a plurality of parts of the tablet machine, and the gantry is driven to hold the parts. a gantry driving mechanism for plane rotating means in a predetermined direction, Ri Na and and a liquid supply means for injecting a cleaning liquid warm water from a nozzle toward a component continues to rotate held in the component holding means, The liquid supply means is horizontal
An upper nozzle arranged almost directly above the rotating component holding means
And an upwardly inclined nozzle disposed obliquely above .

[0007] Also, the parts cleaning device of the tablet machine according to the present invention.

It is characterized by

In the liquid supply means of the present invention, in order to particularly improve the cleaning efficiency, the component holding means is arranged in the opening of the gantry, and the lower nozzle is arranged substantially directly under the opening. It is desirable to provide a downwardly inclined nozzle diagonally below. In addition, as a concrete example of the parts to be cleaned,
You can name the mold.

[0009]

With such a structure, the cleaning liquid is sprayed from the upper nozzle and the upper inclined nozzle of the water supply means toward the component which is rotating in the plane. Therefore, if at least one of the nozzles, that is, the upper inclined nozzle is arranged at a position deviated from the rotation axis of the gantry, the cleaning liquid will be jetted from various directions to the parts, and the dirt will be contaminated. It becomes possible to wash off evenly. In particular, when parts are installed in the opening of the gantry and nozzles are installed above and below the parts, the cleaning liquid can be sprayed from any direction toward the parts, so there is no leftover residue. You can Since powder as a raw material is often randomly attached to parts of the tablet machine after use, it is very meaningful to spray and wash the cleaning liquid from all directions in this way.
