[Structure] The cleaning basket 2 is divided by a partition wall 2C into a cleaning chamber 4A having a plane opening 4B, at least one of which is opened. The maximum diagonal length L1 of the flat opening 4B of the cleaning chamber 4A is L2 ≧ L1 with respect to the axial length L2 of the workpiece W.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cleaning basket that stores a plurality of works when collectively cleaning a plurality of works simultaneously in a cleaning chamber (called batch cleaning).

[0002]

[Prior art]

 Conventionally, when performing such batch cleaning, a work is put in a cleaning basket in advance, and this cleaning basket is placed in a cleaning chamber of a cleaning device for cleaning. One of the cleaning baskets used for such cleaning has a large opening, and workpieces to be cleaned are randomly introduced through this opening.

[0003]

[Problems to be solved by the device]

 According to such a conventional cleaning basket, the work is arranged in a non-aligned manner in the cleaning basket, and in particular, as shown in FIG. 3, the work has a length L2 along the longitudinal axis direction and has a large center portion. In the case of the work W including the passage 1 in which the diameter hole 1A and the small diameter hole 1B are formed, it is difficult to uniformly wash the inside of the passage 1 of all the works W. This is because, for example, in ultrasonic cleaning, the ultrasonic waves emitted from the ultrasonic vibrator in one direction may not act in the passage 1 of the work W. That is, the works W are arranged in a non-aligned manner in the cleaning basket, and the passages 1 of all the works W are not arranged so as to open in one direction so as to face ultrasonic waves.

On the other hand, various work throwing devices are conceivable in order to align the works W in one direction in the washing basket, but the introduction of these devices leads to an increase in capital investment and an increase in the number of work steps, and thus the washing cost Undesirably leading to an increase in.

The present invention has been made in view of the above problems, and provides a cleaning basket in which works can be extremely easily arranged in a line in the cleaning basket without introducing a special work input device. The purpose is to enhance the cleaning effect of the work.

[0006]

[Means for Solving the Problems]

 In the cleaning device for placing a plurality of works in a cleaning basket, arranging the cleaning basket in a cleaning chamber, and cleaning the works in the cleaning basket, a plurality of cleaning chambers in which at least one cleaning basket is opened The maximum diagonal length L1 in the flat opening of each cleaning chamber is L2 ≧ L1 with respect to the axial length L2 of the workpiece.

[0007]

[Action]

 When the end surface of the work faces the flat opening of each cleaning chamber, the work is dropped into the cleaning chamber with L2 ≧ L1 with the end surface facing downward. After a predetermined number of works have been put into the cleaning chamber, the end faces of the works always open downward, so that the works are arranged in a certain direction in the cleaning basket.

【Example】

 An embodiment of a cleaning basket in the cleaning device according to the present invention will be described below with reference to the drawings. 1 is a top plan view of the cleaning basket, and FIG. 2 is a vertical sectional view taken along the line AA of FIG. Reference numeral 2 denotes a box-shaped cleaning basket, and a net 3 is arranged in the bottom opening 2A to close the bottom opening 2A, and the upper opening 2B is opened before the work W is loaded. The closing of the bottom opening 2A is not limited to the mesh 3, and a lattice or the like is appropriately selected. The cleaning basket 2 is divided into a plurality of cleaning chambers 4A by a partition wall 2C, and thus the upper opening 2B is divided into a plurality of square flat openings 4B. The partition wall 2C reaches the bottom opening 2A from the upper opening 2B. In this embodiment, two partition walls 2C are prepared and divided into three cleaning chambers 4A having three plane openings 4B. Then, the maximum diagonal line L1 of each plane opening 4B and the axial length L2 of the work W are set to L2 ≧ L1. In the present embodiment, the shape of the plane opening is quadrangular, but it may be polygonal, circular, or irregular. Therefore, the maximum diagonal of the plane opening is the longest diagonal of the diagonal lines crossing the plane opening. The depth D of the cleaning basket 2 is preferably D> L1 because the work W is stored in the cleaning basket 2.

The work W is put into the cleaning basket 2 as follows. Hold the first work W, and arrange the end surface 1C of the first work W facing the flat opening 4B of the cleaning chamber 4A. According to this, the maximum diagonal L1 in the plane opening 4B is set to L2 ≧ L1 with respect to the axial length L2 of the work W, so that the first work W always falls into the cleaning chamber 4A with the end face 1C facing downward. . Even if the cleaning chamber 4A is inclined, it is always arranged with the end surface 1C of the first work W facing downward. Next, the second work W is held, and the end surface 1C of the second work W is arranged facing the flat opening 4B of the cleaning chamber 4A. According to this, like the first work W, the second work W is placed in the cleaning chamber 4A with the end surface 1C of the second work W facing downward. The same number of the works W as the above is put into the cleaning chamber 4A. When a desired number of workpieces W are loaded into the cleaning chamber 4A in this manner, the inclined arrangement state of the workpieces W is corrected, and the workpieces W are aligned in the cleaning chamber 4A in a substantially vertical state. The end face 1C was always arranged toward the bottom opening 2A.

Then, the cleaning in the cleaning device is performed, for example, as shown in FIG. This example shows an ultrasonic cleaning device, in which an ultrasonic oscillator 11 is arranged at the bottom of the cleaning tank 10 in which the cleaning liquid S is stored, and in the cleaning tank 10, four ultrasonic vibrators are rotated by a shaft 12. The cleaning basket jigs 13 facing each other are arranged. Then, the works W are arranged in an aligned state, and the four cleaning baskets 2 whose upper openings 2B are closed by the net 5 are inserted and arranged in each cleaning basket supporting jig 13. The cleaning is performed by the ultrasonic waves generated by the vibration of the ultrasonic oscillator 11, and the ultrasonic waves are emitted directly to the passages 1 of the work W arranged in the cleaning basket 2 in an aligned state. Since the cleaning basket support 13 is rotated by the shaft 12, the cleaning of the passages 1 of all the works W is uniformly and surely performed. The cleaning device is not limited to ultrasonic cleaning, and may be cavitation cleaning or the like.

[0011]

[Effect of device]

 As described above, according to the cleaning basket of the cleaning apparatus according to the present invention, the end face of the work can be aligned in the cleaning chamber with the end face of the work facing downward by simply disposing the end face of the work so as to face the flat opening of the cleaning basket. It was possible to arrange the workpieces in an array in the cleaning basket very easily and in a short time without introducing a special workpiece input device, which reduces the cleaning cost and further improves the cleaning effect. Was achieved.
