Description

Detailed Description of the Invention (Objective of the Invention) (Industrial Field of Application) The present invention is a method for mounting a cylindrical workpiece after applying an electrical material to the end face of the workpiece for surge absorption of a cylindrical workpiece used for insulators, etc. The present invention relates to a cylindrical workpiece transfer device that transfers a cylindrical workpiece from a tool to a cylindrical workpiece receiving tray when loading the cylindrical workpiece into a firing furnace.

(Prior art) As a method of applying electrically resistive material to the end surface of a workpiece, there is a primitive method in which a cylindrical workpiece is fitted into the fitting part of a workpiece mounting jig with the surface to be coated facing up, and the material is applied using a roll or the like through a screen. The method is well known.

The cylindrical workpiece with the electrically resistive material applied to both end faces is placed on a mounting jig with both end faces facing up and down, as shown in Figures 11 and 12. In this state, it is transported to a firing furnace and fired.

(Problem to be Solved by the Invention) However, even if the cylindrical workpiece is transported to the firing furnace in this state, the lower end surface of the cylindrical workpiece is in contact with the mounting surface of the mounting jig. has the disadvantage that it does not cook well.

Therefore, it is conceivable to move the workpiece to another tray or the like to release both end surfaces, but since the cylindrical workpiece is small, it is difficult to align it in the tray or the like.

The present invention has been made with the aim of eliminating such problems.

(Structure of the invention) (Means for solving the problem) This problem can be solved by transferring the cylindrical workpiece to another tray,
This problem is solved by ensuring that both end surfaces of the cylindrical workpiece do not come into close contact with the receiving plate.More specifically, the configuration requirements are as follows: The end surfaces of the cylindrical workpiece are coated with an electrically resistive material, and both end surfaces are placed one above the other. Place the cylindrical workpiece on the cylindrical workpiece mounting jig with both end surfaces facing up and down! l! After transferring the plurality of cylindrical workpieces on the fl jig to the L-shaped bottom of an L-shaped rolling jig with a length that allows them to be placed in a row, the cylindrical workpieces are rotated so that the raised part of the L-shaped chamber is at the bottom. A chevron-shaped cylindrical workpiece receiving tray having a chevron-shaped groove made of unevenness that holds the cylindrical surface of the cylindrical workpiece by changing the position of the surface and both end faces and tilting the L-shaped rolling jig to utilize the rolling of the cylindrical workpiece. The present invention is a cylindrical workpiece transfer device characterized by sequentially transferring cylindrical workpieces to a groove.

(Example) Next, embodiments of the present invention will be described based on the drawings.

The same side view, FIG. 3 is a perspective view of the L-shaped rollover jig, FIG. 4 is a view taken along the line A-A in FIG. 3, and FIG. 5 is a state in which the cylindrical workpiece is placed on the rollover jig. 6 is a plan view of the same, FIG. 7 is a plan view of the transfer jig, FIG. 8 is a view taken along the line A-A in FIG. 7, and FIG. 9 is a plan view of the tray. 10 is a view taken along the line A-A in FIG. 9, and FIG. 11 is a plan view of a cylindrical workpiece coated with an electrically resistive material and placed on a mounting jig. FIG. 12 is a partially detailed sectional view thereof.

In the drawings, 1 is an L-shaped rolling jig, 2 is a transfer jig, 3 is a cylindrical workpiece receiving tray, 4 is a cylindrical workpiece mounting jig, and 5 is a cylindrical workpiece.

As shown in FIGS. 3 and 4, the L-shaped rolling jig 1 has a cross-sectional shape and has a length that allows one row of workpieces 5 on the workpiece mounting jig 4 to be placed on the L-shaped bottom 11. It is formed by 13
is a knob for rotating the L-shaped rollover jig 1 by approximately 90 degrees, and rolls over the cylindrical workpiece 5 placed thereon with the L-shaped chamber lift part 12 as the bottom. It is attached to one end of a shaft that is fixed along the length direction to a part of the L-shaped corner of the jig 1.

As shown in FIGS. 7 and 8, the transfer jig 2 has a plurality of grooves 21 having a width that can accommodate both end surfaces of the cylindrical workpiece 5 in a plate body, partitioned by rising walls 22, and forming a plurality of grooves 21 at both ends of the grooves. It's open.

As shown in FIGS. 9 and 10, the cylindrical workpiece receiving tray 3 has a concave surface that holds the cylindrical surface of the cylindrical workpiece 5.
It has a chevron-shaped groove 33 formed by repeating the above steps.

Thus, the overall structure is a transfer device that transfers the cylindrical workpiece 5 on the cylindrical workpiece mounting jig to the cylindrical workpiece receiving tray 3.

(Function) Since the present invention is made as described above, it is used in the following manner.

The cylindrical workpiece 5 whose end face is coated with an electrically resistive material and placed on the cylindrical workpiece mounting jig 4 with both end faces facing up and down is held by a holding device that holds the inner wall of the cylindrical workpiece 5. As shown in the drawings and FIG. 6, they are placed one row at a time on the L-shaped bottoms 11 of a plurality of L-shaped rollover jigs 1 arranged in parallel. After the cylindrical workpiece 5 is placed on the L-shaped bottom part 11, it is mechanically or manually rotated by 90 degrees using the knob 13 so that the rising part 12 becomes the bottom part. In this embodiment, when the rubber dog 6 is brought into contact with the lower side of the knob 13 and moved in the direction of the arrow, the L-shaped rollover jigs arranged in parallel will move 90ff! ,Rotate.

Next, as shown in FIGS. 1 and 2, a plurality of L-shaped jigs arranged in parallel are connected to the groove 22 at one end of the transfer jig 2 shown in FIGS. 7 and 8, and the jigs are transferred. The other end of the mounting jig 2 is a cylindrical workpiece receiving tray 3 shown in FIGS. 9 and 10.
The cylindrical workpiece 5 is sequentially moved into the chevron-shaped groove 33 while tilting the rollover jig 1 and the transfer jig 2, and shifting the contact portion between the chevron-shaped groove 33 and the transfer jig 2. Transfer. Although the transfer jig 2 is used in this embodiment, it is also possible to directly transfer the workpiece from the overturning jig 1 to the cylindrical work receiving tray 3.

Thus, both end surfaces of the cylindrical workpiece are released, and the cylindrical surface is held in the chevron-shaped groove 33 of the cylindrical workpiece receiving tray 3.

After this, the cylindrical workpiece 5 is moved to the cylindrical workpiece receiver ff[13,
It is transported to a kiln and fired. Since the work tray 3 is placed in a firing furnace, it is of course limited to materials that can withstand firing, and is preferably made of ceramic, for example.

(Effects of the Invention) Since the present invention is made as described above, it has the following effects.

■ Since a rolling jig is used, the position of the cylindrical workpiece can be easily changed, both end faces of the cylindrical workpiece can be released, and the workpiece can be transferred to the cylindrical workpiece receiving tray.

- Since the rollover jig is formed into an L shape, the mounting position of the cylindrical workpiece can be easily changed by simply replacing the L-shaped bottom and the L-shaped chamber riser.

■ The cylindrical workpiece receiving tray has a chevron-shaped groove with repeated unevenness, and since the cylindrical surface of the cylindrical workpiece is held here, both end surfaces of the cylindrical workpiece are released.

(2) Since both end faces of the cylindrical workpiece are released, the problem of insufficient firing of one end face as in the conventional method when firing a cylindrical workpiece in a firing furnace is eliminated.
