Description

Detailed Description of the Invention (Field of Industrial Application) The present invention is applicable to application cylinders and pressure cylinders for printing coating such as gravure printing and resin liquid coating, or heating and cooling cylinders for printing and coating. The present invention relates to a cylinder picking device used for lifting or moving a cylinder having a hole in which a rotating shaft is installed in the thrust direction, with the axial direction of the cylinder perpendicular.

(Prior Art) In a conventional cylinder pinking device, for example, as shown in FIG. 3, a bracket 1 is attached perpendicularly to a support shaft 2, and a pair of left and right arms 3 are attached to the bracket 1 by supporting shafts 3a.
A pair of left and right arms 4 are pivotally supported on the support part 5 at the midpoint 5a of the arms 4, and the lower end of the vertical shaft 2 is placed in a sliding guide 6 integrally provided with the support part 5. Insert the part,
One end of the arm 3 and the arm 4 are connected by a connecting portion 4b.

A hook portion 4a is provided at the other end of the pair of arms 4, respectively. Then, by pushing the support shaft 2 downward into the slide guide part 6,
By lowering the bracket 1, the ends of the pair of arms 4, 4 on the side of the hooks 4a can be closed, and conversely, by pushing the support shaft 2 upward within the slide guide part 6, the hooks of the arms 4, 4 can be closed. The tip on the side of part 4a can be opened. However, in the beer king operation, the hook portion 4a is inserted into the hole C2 in the side surface C1 of the printing cylinder 〇 (a gravure plate in which image cells are formed on the surface of the cylinder vertically oriented in the pongee direction). , 4a, it is necessary to close the hook by the width of the hole C2. Therefore, a hole 2a for a stopper is provided at the lower end of the support shaft 2 in a direction perpendicular to the shaft 2, and a pin 7 is loaded into the hole 2a, so that the shaft 2 has a hook portion 4a, On the other hand, after loading is completed, the bottle 7 is pulled out and the hook 4a+4a is hooked onto the flange C3 of the hole C2. .

As described above, the conventional picking device as described above requires a stopper mechanism (stopper pin) to maintain the retractable picking hook in the open state and the closed state.
Further, it is necessary to manually attach and detach the stopper pin, which is a troublesome operation. Furthermore, even if the stopper pin 7 of the conventional picking device is pulled out, unless the support shaft 2 is raised, the hook portion 4a,
4a does not open. Therefore, the pinking operation requires discontinuous operation in two stages: driving the support shaft 2 downward or upward and mounting or pulling out (separating) the stopper pin.

(Object of the Invention) The present invention provides a method for maintaining the opening/closing type picking hook provided in the pi-7 gripping hand of a cylinder picking device in an open state or a closed state by using the conventional lifting and lowering movement of a support shaft and manual work. This eliminates the discontinuous operation caused by the two-stage operation of attaching the stopper and releasing the jIl, and enables the pinking operation of the cylinder to be performed by a series of continuous operations.

(Structure of the Invention) The present invention includes a hand main body support part 9 connected to a movable part A of a freely movable cylinder picking device main body, a pair of left and right arms 10 pivotally supported by the support part 9, and A bracket 12 is slidably attached to the support part 9, and a pair of left and right bending arms 15.15 are pivotally supported by the bracket 12 via bending points 14.14,
One end of said arm 10.10 and said bending arm 15.
This cylinder picking device is characterized in that it has a link mechanism that connects one end of the bending arm 15.15 with a connecting portion 10a, and the other end of the bent arm 15.

(Function of the Invention) The present invention makes the bracket 12 that pivots the pair of bending points 14 of the picking hooks 15c and 15c of a cylinder picking device movable, and normally stops the bracket 12 from lowering by its own weight or by a push-down spring. At the position of the point, the pair of left and right hooks 15a, 15a are in an open state, and when the hooks are installed in the hole C2 of the side surface C1 of a cylinder C such as a printing plate, the handle 18. 19 by hand and manually lift the bracket 12 upward, or by shortening the slide shaft consisting of an operating rod such as an air cylinder or a hydraulic cylinder, lift the bracket 12 upward, and remove the pair of left and right brackets. The lower arms 15b, 15b can be closed by means of a linkage consisting of the upper arms 15a, 15a of the arm 10.10 and the bending arm 15.15, respectively, whereby the pair of left and right hooks at the tips of the arms 15b, 15b can be closed. This is to bring the portions 15c, 15c into a closed state.

After the hook portions 15c, 15c are in the closed state, the tips of the arms 15b, 15b are loaded into the hole C2 of the side surface C1 of the cylinder C, and after loading, the handle is gripped by hand. is released and the bracket 12 is lowered by its own weight, or by extending the air cylinder rond, the bracket 12 is lowered, and the hook portions 15c, 15c are inserted into the inside of the flange portion C3 of the hole portion C2. By positioning the movable part A vertically using appropriate means, the hook part 15c,
15c can be engaged with the inside of the flange portion C3 to lift the cylinder 〇 upward. As a result, the pinking hook portion 15 is inserted into the hole C2 of the cylinder C.
A, 15a does not require a conventional stopper bin for the loading operation, and can be installed smoothly.

(Example) The apparatus of the present invention will be explained in detail according to examples.
