The center of the large diameter portion 81 and the center of the small diameter portion 83 coincide with each other, and when the container R1 with a lid mounted on the rotary table 3 is clamped, the large diameter portion 81 and the small diameter portion 83 are used. Is in line contact with the container R1 with a lid (lid R3). The outer diameter of the large diameter portion 81 is smaller than the outer diameter of the rotary table main body 13, and the center of the large diameter portion 81 and the small diameter portion 83 and the center of the rotary table main body 13 are one to each other in a plan view. I am doing it.

The container contact member drive unit 79 includes a base body 87, a guide rod 89, a connecting member 91, an actuator 93 such as a pneumatic cylinder, and a container contact member support 95 with a lid.

The base body 87 is integrally provided on the housing 29. The guide rod 89 has its longitudinal direction in the vertical direction, is supported by the base body 87 via a linear guide bearing (not shown), and is movable with respect to the base body 87 and the housing 29. ..

For example, two guide rods 89 are provided, and they are arranged apart from each other in the X direction. A connecting member 91 is provided at the lower ends of the two guide rods 89. As a result, the two guide rods 89 and the connecting member 91 are integrated.

In the pneumatic cylinder 93, a cylindrical cylinder body 97 is integrally provided with the base body 87, the cylinder rod 99 extends downward from the base body 87, and the lower end of the cylinder rod 99 is a connecting material. It is joined to 91.

The container contact member 11 with a lid is supported by the connecting member 91 under the connecting member 91 via the container contact member support 95 with a lid. As a result, the container contact member 11 with a lid extends in the vertical direction and becomes rotatable with respect to the connecting member 91 about the axis C2 passing through the center of the container contact member 11 with a lid. There is. The axis C2 and the axis C1 coincide with each other.

Then, as the cylinder rod 99 moves in the vertical direction, the two guide rods 89, the connecting member 91, the container contact member support 95 with a lid, and the container contact member 11 with a lid move in the vertical direction. , The container R1 with a lid placed on the rotary table 3 is clamped and unclamped (see FIG. 4).

As shown in FIG. 4, the lower portion of the two guide rods 89, the connecting member 91, the container contact member support 95 with a lid, and the container contact member 11 with a lid are located in the upper space 39. positioned.

Next, the container installer 25 with a lid will be described.

The container installation tool 25 with a lid is also made of a bar 15 in the same manner as the container contact member 11 with a lid (see FIG. 13).

A plurality of (for example, three) container installation portions 27 of the container installation tool 25 with a lid are provided, and as shown in FIG. 14, three sizes of the container with a lid R1 (large container with a lid R1a, medium size) are provided. Either the large container with a lid R1b or the small container with a lid R1c is installed in any of the two container installation portions 27a, 27b, and 27c of the container installation tool 25 with a lid.

When viewed in a plan view, the center of the lidded container R1 (R1a, R1b, R1c) installed on the lidded container installer 25 coincides with the rotation center C1 of the rotary table 3.

Next, the operation of the cleaning device 1 will be described.

In the initial state, the container R1 with a lid is not placed on the rotary table 3, the shutter 45 is raised, the opening 43 of the side plate portion 33A is open, and the container contact member 11 with a lid is raised. It is assumed that the injection of the cleaning liquid from the cleaning liquid injection unit 5 has stopped.

In this initial state, the container R1 with a lid is carried into the housing 29 from the opening 43, and the container R1 with a lid is placed on the rotary table 3.

Subsequently, the shutter 45 is lowered to close the opening 43, the container contact member 11 with a lid is lowered, and the container R1 with a lid is clamped by the clamp portion 9.

Subsequently, the rotary table 3 (rotary table main body 13) is rotated, and the cleaning liquid is sprayed from the cleaning liquid injection unit 5 when or before the rotation speed of the container R1 with a lid reaches or becomes the first rotation speed. Then, the outer surface of the container R1 with a lid is cleaned.

After rotating the rotary table 3 and injecting the cleaning liquid from the cleaning liquid injection unit 5 for a predetermined time, the injection of the cleaning liquid from the cleaning liquid injection unit 5 is stopped, the rotation speed of the rotary table 3 is increased, and the container R1 with a lid is used. It rotates at the second rotation speed to dehydrate the outer surface of the container R1 with a lid.

Subsequently, the rotation of the rotary table 3 is stopped, and after the rotary table 3 is stopped, the container contact member 11 with a lid is raised to release the clamp of the container R1 with a lid, and the shutter 45 is raised to open the opening 43. The container R1 with a lid that has been opened, washed and dehydrated is carried out of the housing 29 through the opening 43.

Subsequently, in the same manner, the next container with a lid R1 is washed and dehydrated.

According to the cleaning device 1, the cleaning liquid is sprayed from the cleaning liquid injection unit 5 toward the container R1 with a lid, and since the rotary table 3 is rotating at this time, the lid is generated by the centrifugal force generated by the rotation of the rotary table 3. The cleaning liquid on the outer surface of the attached container R1 flies away from the lidped container R1 to the outside of the covered container R1 (jumps away from the central axis C1 of the rotary table 3).

As a result, the cleaning liquid does not enter the inside of the container R1 with a lid through a very small gap between the container body R2 and the lid R3, and the outer surface of the container R1 with a lid containing the cushioning material R5 inside is covered with a lid. Cleaning can be performed so that the cleaning liquid does not enter the inside of the attached container R1.

In the container R1 with a lid whose outer surface was cleaned and the cushioning material R5 was contained inside, the lid R3 was removed in a clean room, and electronic parts, a printed circuit board R4, etc. and the cushioning material R5 were placed inside. Later, the lid R3 is removed and used for shipping electronic components, printed circuit boards R4, and the like.

Further, the outer surface of the container with a lid R1 can be cleaned in a shorter time than by manually cleaning by air blow, and the degree of removal of dust and the like does not vary. That is, the outer surface of the plurality of lidded containers R1 can be cleaned without causing variation among the lidded containers R1.

Further, since the cleaning liquid is used instead of the compressed air, the dust does not fill the room and adhere to the outer surface of the container R1 with a lid again, and the deterioration of the working environment such as dust pollution is prevented.

Further, according to the cleaning device 1, since the lidded container R1 is sandwiched between the rotary table 3 and the clamp portion 9 and the lidded container R1 is integrated with the rotary table 3, the lidded container R1 is rotated by the rotation of the rotary table 3. Can move with respect to the rotary table 3 and, for example, can eliminate the occurrence of a situation such as falling to the outside of the rotary table 3.

Further, in a state where the container R1 with a lid is sandwiched between the rotary table 3 and the clamp portion 9, a flat surface in which the container main body R2 and the lid R3 are in contact with each other (a “square” -shaped flat surface having a predetermined width). However, since it is urged, the inside of the container with lid R1 passes through a flat surface (a very small gap between the container body R23 and the lid R3) in which the container body R2 and the lid R3 are in contact with each other. The invasion of the cleaning liquid can be suppressed more reliably.

Further, according to the cleaning device 1, the rotary table main body 13 is composed of an elongated rod material 15, and the cleaning liquid sprayed upward from the first cleaning liquid injection portion 19 toward the lidded container R1 is the rotary table main body. Since it is configured to pass through the space between the rods 15 constituting the 13 and reach the container R1 with a lid, the container R1 with a lid is placed even though it is placed on the rotary table 3. The cleaning liquid can be sprayed toward the lower surface, and the lidded container R1 can be reliably cleaned.

Further, since the container contact member 11 with a lid is also made of an elongated rod material 15, the cleaning liquid can be sprayed on the upper surface of the container R1 with a lid even though it is clamped by the clamp portion 9, and the lid can be sprayed. The attached container R1 can be reliably washed.

Further, according to the cleaning device 1, the cleaning liquid is sprayed from the cleaning liquid injection unit 5 for a first predetermined time in a state where the rotary table 3 is rotated at the first rotation speed, and then the second rotation speed is used. Since the rotary table 3 is rotated for a predetermined time, the container R1 with a lid can be dehydrated immediately after cleaning by spraying the cleaning liquid, and the dirt on the outer surface is removed and water droplets are attached to the outer surface. A container with no lid R1 can be obtained in a short time.

Further, when the container installation tool 25 with a lid is used, the container installation tool 25 with a lid includes a plurality of container installation portions 27 having different sizes from each other, and the container installation tool 25 with a lid is positioned at a predetermined position on the rotary table 3. Since it is placed and installed on the rotary table 3, each of a plurality of types of containers with lids R1 having different sizes can be positioned and installed with respect to the rotary table 3. As a result, the rotary table 3 on which the container R1 with a lid is placed can be rotated without losing the balance.

When the container installation tool 25 with a lid is not used, a positioning member such as a positioning pin may be provided on the rotary table main body 13 so that the container R1 with a lid can be positioned with respect to the rotary table main body 13.

Further, in the above description, one lidded container R1 is placed on one rotary table 3 for cleaning and dehydration, but two or more lidded containers R1 are placed on one rotary table 3. It may be placed and washed and dehydrated. In this case, the containers R1 with lids are separated from each other by the rotary table 3.

Further, the above-mentioned contents may be grasped as an invention of a washing method (washing / dehydrating method).

That is, in the method of cleaning the outer surface of the container with a lid using the cleaning liquid, it may be grasped as a cleaning method of injecting the cleaning liquid toward the container with the lid while the container with the lid is rotating.

When rotating the container with a lid, it is desirable that the container with a lid is placed on a rotary table and is sandwiched between the rotary table and a clamp portion. It is desirable that the container with a lid is integrated with the rotary table.

Further, after the cleaning liquid is sprayed over a first predetermined time in a state where the rotary table is rotated at the first rotation speed, the injection of the cleaning liquid is stopped, and the second rotation speed is faster than the first rotation speed. It may be grasped as a cleaning method of rotating the rotary table over a second predetermined time at the rotation speed of.
