Description

Detailed Description of the Invention (Industrial Field of Application) This invention relates to automatic opening of the lid of a barrel tank in a planetary rotating barrel processing machine that processes the contents in the barrel tank by polishing, stirring, mixing, pulverizing, etc. It relates to equipment and belongs to the field of production and use of barrel processing machines.

(Prior Art) Conventionally, planetary rotating barrel processing machines have been widely used due to their high processing efficiency. This barrel processing machine usually has four barrel tanks, and the operation of opening the barrel lids is fully automated, but the lids are opened one by one (Japanese Patent Application Laid-open No. 53157/1983).

(Problems to be Solved by the Invention) As mentioned above, the conventional lid opening operation was performed for each tank, which had the drawback of requiring a large amount of time.
In other words, while processing usually takes a few minutes to complete, opening the lids of four tanks and replacing the contents can sometimes take more than 30 minutes, during which time the processing machine is stopped. This resulted in a decline in operating efficiency and halved the much-needed processing efficiency.

(Means for solving the problem) A rotary plate having a plurality of notches is attached to the center axis of a planetary rotating barrel processing machine having a plurality of barrel tanks and is slidable in the axial direction. A plurality of barrel lids corresponding to each barrel tank were rotatably supported on the rotary disk, and the barrel lids were configured to close the openings of the barrel tanks.

(Operation of the invention) According to the present invention, since all the barrel lids corresponding to the openings of each barrel tank are placed on the rotary disk, the barrel lids corresponding to the openings of each barrel tank are all placed on the rotary disk, so that the barrel lids corresponding to the openings of each barrel tank are all placed on the rotary disk. The lid can be opened at the same time. Further, since the rotary disk is provided with cutouts corresponding to the number of barrel tanks, the contents can be loaded or discharged through the cutouts.

(Embodiments) Next, details of the present invention will be described with reference to embodiments shown in the accompanying drawings. Fig. 1 is a longitudinal sectional front view of an embodiment of the present invention, Fig. 2 is a partially enlarged sectional view, Fig. 3 is a cross-sectional plan view of the rotary disk, and Fig. 4 is a use of the automatic lid opening device of the invention.

The opening 12 of No. 3 faces the input ports 52, 52a of the chute 50, 50a, and the yoke 8 is fixed with a notch.

On the other hand, when all the media and unprocessed workpieces are stored in the buckets 53, 53a, the bucket lift motor 56 is driven to raise and lower the buckets 53, 53a.
and falls over the chute 50, 50a. As a result, the cells in the buckets 53, 53a are divided into two, and the four cells are simultaneously charged into the barrel tank 23 through the respective input ports 52, 52a. When you have finished inserting the squares, move the chute 50, 50a again to the 6th
It rotates as shown in the figure and drives the barrel lid index motor 41 to rotate the rotary disk 9 together with the barrel lid 13 by 45 degrees in the opposite direction. Thereby, the barrel lid 13 is moved to a position corresponding to the opening 12 of the barrel tank 23.

Next, pressure fluid is introduced into the piston side of the fluid pressure cylinders 7, 7, the mounting plate 4 is advanced, and the opening 12 of the barrel tank 23 is pressed with the barrel lid 13,
Close the lid completely. With the above steps, one cycle is completed.

(Effects of the Invention) This invention places each lid of all the barrel tanks on a rotary disk, and supports the rotary disk so that it can slide in the axial direction with respect to the center axis of the planetary rotating barrel processing machine. The lids of all tanks can be opened and closed automatically at the same time.
Therefore, the time required for incidental work other than barrel processing can be extremely shortened.
