Abstract

PURPOSE:To switch the rotating direction of a cylindrical barrel by rotating an opening and closing lid along the outer peripheral surface of the cylindrical barrel, and thereby transmitting a torque to the cylindrical barrel to automatically open and close the cylindrical barrel by the opening and closing lid. CONSTITUTION:An article 25 to be treated is charged into the cylindrical barrel 21 from a charging port 24, a driven wheel 20 is counterclockwise rotated, hence the charging port 24 is clod by the opening and closing lid 22, and the tip 56 of a cam follower 39 is engaged with the recess 51 of an arcuate cam. When the driven wheel 20 is further rotated, a torque is transmitted to the cylindrical barrel 21 through a radial end edge 54 and an abutting piece 52, and the cylindrical barrel 21 is rotated while the charging port 24 is closed. When the driven wheel 20 is then clockwise rotated, the opening and closing lid 22 and the arcuate cam 37 are clockwise rotated, the cam follower 39 is rolled, and the tip 56 id detached from the recess 51. When the opening and closing lid 22 is rotated to a position where the charging port 24 is opened, the radial end edge 55 is abutted on the abutting piece 53, the torque is further transmitted to the cylindrical barrel 21 by the rotation of the driven wheel 20, the lid is rotated while the charging port 24 is opened, and the article 25 to be treated is discharged.

Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a rotating barrel device used in surface treatment processes such as electroplating. rmty+
Rotating barrel lI that can discharge the processed product
It concerns M.

(Prior art) As a conventional rotating barrel device of this type, the U.S. Pat.
Publication No. 826 discloses that, as shown in PIS 9, an opening 2 is formed in a barrel 1 formed into a hexagonal cylinder with a plate having a large number of holes, and one end of this opening 2 is pivoted to a pivot #+3. Been!
A rotary barrel Vt5 is shown in the dark, which is planted so that it can be opened by a shade 1712!5 whose end is made to overlap the inside of the adjacent side 4 which is longer than that side. According to this rotating barrel device, when the barrel 1 is rotated counterclockwise, even if the opening 2 is tilted downward, the other end of the barrel comes into contact with the side 4, so that the objects to be processed inside the barrel 1 will not fall. First, when rotating clockwise, 1111m2E5 overlaps side 6 and the opening is opened, causing the workpiece to fall.

In addition to the conventional device described above, a rotating barrel device having a spiral cross-sectional shape is also in practical use. According to this NA winding type rotating barrel device, as long as the barrel is rotated in the direction toward the center of the vortex 8, the products to be processed enter from the input port toward the center of the vortex and are deposited near the center. It will not fall out of the mouth, and to eject the product, simply rotate the barrel in the opposite direction, and as it rotates, the product will naturally be sent out from the center to the input port along the spiral. .

(Problem to be Solved by the Invention) In the above-mentioned hexagonal rotating barrel device, since mm1s is structured to swing inside the barrel 4, the amount of processing material at one time is determined by the swinging motion of IJFI17Iri5. The processing capacity was limited to a range that was not blocked by the product, and the processing capacity was low.

Furthermore, even in the case of a spiral-type rotating barrel device, the throughput at one time is limited to the amount that can be stored in the center of the spiral, so the throughput is low despite the large external dimensions.

(Means for Solving the Problems) In view of the above-mentioned problems and α, the present invention provides a mechanism for automatically opening and closing the #1 closing valve by switching the direction of rotation of the barrel, and for rotating with high throughput despite its small size. The purpose is to provide barrel equipment.

The present invention has a structure in accordance with such an object: a frame, a cylindrical barrel rotatably attached to the frame and having a charging opening on its outer circumferential surface, a driven wheel rotatably attached to the frame, and a cylindrical barrel rotatably attached to the frame, and a driven wheel rotatably attached to the frame; The opening m2 rotates integrally with the driving wheel m along the line and opens the input opening W by 123 IIg! and,
It has a small diameter and a large diameter outer peripheral edge, and both outer circumferences! 5Ait
an arcuate cam formed with four parts and rotating integrally with the driven wheel; and a radial edge of the arcuate cam fixed to the side surface of the cylindrical barrel with an angle required to open and close the input opening. A pair of abutting pieces are attached to the side surface of the cylindrical barrel via a pivot shaft, and a PAl plate is attached to the side of the cylindrical barrel through a pivot shaft, and has a PAl plate whose curvature is approximately equal to the curvature of the small shuttle and large diameter outer peripheral edge of the arc-shaped cam. The opening/closing lid opens the input IJ110 into
The gist of the present invention is a rotating barrel f1rf1 that is equipped with a lower cam 7 having a tip end that engages with the concave portion.

(Function) According to the above configuration, when the driven wheel is connected to the drive source and driven in the forward/j direction, the a-driven wheel and III 12! The lid and the arcuate cam rotate, but no torque is transmitted to the cylindrical barrel until the radial edge of one of the arcuate cams is aligned with the other piece. Expedition
The lid rotates relatively and the input opening is opened. During this period, the lower cam 7t slides into contact with the outer periphery ra edge of the arc-shaped cam as it rotates, and when the input opening is m, the radial edge of the arc-shaped cam abuts against the abutment piece, and the cam 7t contacts the concave portion. The tip of roller 7 engages. When the driven wheel continues to rotate in the forward direction, torque is transmitted to the circular barrel via the abutment piece that abuts against the arc-shaped cam, and the total cylindrical barrel is rotated in the forward direction.

When the drive source and the driven wheel are disconnected, the opening/closing lid and the cylindrical barrel become relatively free to rotate, but the tip ran of the cam 7f lower engages with the recess and prevents the opening/closing lid from rotating, so the opening/closing lid is shaped like an arc. Is it idle 1 as long as the cam doesn't rotate? ! The lid is held in position to open the input opening.

Next is Kakeru! lI! If you connect J i and the driven wheel and drive the driven wheel in the opposite direction, darkness! ■Lid and arc-shaped cam)! ! ! However, the cylindrical barrel does not rotate by ~1° until the other radial edge of the arc-shaped cam abuts the other abutting piece. Key - 1 turn and the tip part separates from the recess. When the input 110 is 111 & again, the radial edge of the arc-shaped cam collides with the abutment piece, and torque is transmitted to the cylindrical barrel.The circular part/irel rotates in the opposite direction with the input opening open. .

are free to rotate relative to each other, but since the tip 56 of the lower cam 7t is engaged with the recess 51, even if the workpiece 25 in the cylindrical barrel 21 moves and the center of gravity changes, the circular arc Unless the shaped cam 37 rotates, the barrel 21 will not rotate and will open m? ! 22, the input opening 24 is j'! 1
The state remains the same.

Next, when the driven wheel 20 is rotated in the 5F direction when the round buntle 21 is stopped in the state shown in FIG. 7, for example,
As shown in FIG. 8, the opening/closing lid 22 and the arcuate cam 376
