The cylinder portion 116 is an air cylinder and is connected to a pair of connecting members 111C of the grip portion 111. The cylinder portion 116 moves the moving gripping member 111B toward the fixed gripping member 111A by expanding and contracting the other end side of each connecting member 111C. In this way, by urging the second gripping surface 114a of the moving gripping member 111B toward the first gripping surface 113a of the fixed gripping member 111A, the laminated core 8 is gripped in the vertical direction.

(Hand valve)
The hand valve 117 shown in FIG. 1 is connected to the cylinder portion 116, and operates the cylinder portion 116 by supplying air to the cylinder portion 116. Specifically, in the hand valve 117, when the hand lever 117a connected to the valve (not shown) is rotated, the valve is opened and closed, and the flow of air supplied to the cylinder portion 116 is switched to switch the cylinder portion 116. move.

(Lock mechanism)
The lock mechanism 115 shown in FIGS. 4 and 5 is a mechanism for suppressing the rotation of the grip portion 111 by the rotating portion 112, and is arranged in the vicinity of the rotating portion 112.
The lock mechanism 115 has a lock portion 115A made of a plate member that can move up and down, and a convex portion (engagement portion) 115a attached to the upper end of the lock portion 115A. The convex portion 115a is provided on the inner surface side of the lock portion 115A and exhibits a columnar shape extending inward in the axial direction. In the present embodiment, for example, it has a cylindrical shape, but the shape is not particularly limited.

<Laminated core reversing work by laminated core reversing device>
Next, a case where the laminated core is cleaned by using the laminated core reversing device 100 of the present embodiment will be described.
First, before using the laminated core reversing device 100, it is confirmed that the fixed gripping member 111A of the core reversing mechanism 11 is in the lower position and the moving gripping member 111B is in the upper position.
Then, the operator pushes the laminated core 8 discharged from the welding device to the transport mechanism 10 of the laminated core reversing device 100 and moves it onto the transport surface 101a of the carry-in portion 101. The heavy laminated core 8 can be moved with a light force by rotating the plurality of transport rollers 101A.

In the present embodiment, for example, after moving onto the transport surface 101a, an operator cleans the surface (upper surface, outer peripheral surface) of the laminated core 8 after welding. Alternatively, the surface may be cleaned before the laminated core 8 is conveyed to the laminated core reversing device 100.

The laminated core 8 on the transport surface 101a is further pushed toward the core reversing mechanism 11 to move it onto the first gripping surface 113a of the fixed gripping member 111A. At this time, the laminated core 8 can be further moved to the back by the rotation of the plurality of gripping rollers 113. The laminated core 8 moved to the back of the core reversing mechanism 11 stops by abutting against a pair of core support members 104 (FIG. 3) arranged vertically.

With the laminated core 8 arranged between the fixed gripping member 111A and the moving gripping member 111B, the operator operates the hand lever 117a (hand valve 117) to operate the cylinder portion 116. The moving gripping member 111B is lowered according to the operation of the cylinder portion 116, and the second gripping surface 114a of the moving gripping member 111B comes into contact with the upper surface of the laminated core 8. In this way, the grip portion 111 is closed, and the laminated core 8 is gripped by the fixed grip member 111A and the moving grip member 111B (FIG. 8).

Next, the lock mechanism 115 unlocks the rotating portion 112 (FIG. 4), and the handle portion 118 is rotated. The lock may be released in conjunction with the operation of the cylinder portion 116.
In the present embodiment, as shown in FIGS. 6 and 7, by rotating the handle portion 118 counterclockwise, the pair of core receiving portions 104A side of the grip portion 111 is gripped while passing below the rotation shaft O. The unit 111 rotates and the direction is reversed.

At this time, since the core support member 104 of the grip portion 111 rotates while supporting the upper and lower ends of the laminated core 8, the laminated core 8 can be turned upside down without falling off from the grip portion 111. That is, since the laminated core 8 is in a state where only the upper and lower sides thereof are gripped, when the laminated core 8 is turned sideways with rotation, gravity is applied to the side that is not gripped. In the present embodiment, since the core receiving portion 104A is provided for each of the gripping members 111A and 111B of the gripping portion 111, even if the laminated core 8 lays down during rotation, the outer peripheral surface side can be supported and gripped. The laminated core 8 is prevented from falling off from the portion 111.

In this way, the grip portion 111 is rotated so that the fixed grip member 111A is located above and the moving grip member 111B is located below. As shown in FIG. 5, in the state after rotation, the recess 112a of the rotating plate 112A is located above.

After finishing the rotation of the grip portion 111, the hand valve 117 is operated again to operate the cylinder portion 116, and the moving grip member 111B is moved in the direction away from the fixed grip member 111A (downward side). When the moving gripping member 111B moves downward, the gripping portion 111 opens, and the gripping of the laminated core 8 is released. The laminated core 8 in this state is in a state of being turned upside down, and the surface that was on the lower side after the welding process faces upward.

Next, the laminated core 8 is pushed out from the core reversing mechanism 11 and moved onto the transport surface 102a of the carry-out portion 102 (FIG. 8). As it is, the laminated core 8 is further pushed forward and moved onto the core support surface 103b of the cleaning unit 103. In the cleaning unit 103, the remaining portion of the surface of the laminated core 8 that could not be cleaned, that is, the lower surface after the welding process is cleaned.

After cleaning is completed, the laminated core 8 is pushed back to the carry-out portion 102 and moved to the grip portion 111. Since the grip portion 111 at this time is in a state after rotation, a pair of core receiving portions 104A are located on the carry-in portion 101 side. Therefore, the laminated core 8 can be moved into the grip portion 111 without being disturbed by the core receiving portion 104A.

Next, when the hand lever 117a (hand valve 117) is operated to raise the moving gripping member 111B toward the fixed gripping member 111A by driving the cylinder portion 116, the hand lever 117a (hand valve 117) is placed on the second gripping surface 114a. The laminated core 8 approaches the fixed gripping member 111A, and the upper surface of the laminated core 8 comes into contact with the first gripping surface 113a of the fixed gripping member 111A. In this way, the grip portion 111 is closed again, and the fixed grip member 111A and the moving grip member 111B grip the laminated core 8 in the vertical direction.

Next, the lock mechanism 115 unlocks the rotating portion 112 to rotate the handle portion 118. At this time as well, the lock may be released in conjunction with the operation of the cylinder portion 116. In this state, by rotating the handle portion 118 in the opposite direction (clockwise), the grip portion 111 is rotated and returned to the initial position. When the grip portion 111 is reversed, the pair of core support members 104 are rotated so as to pass below the rotation axis O, so that the laminated core 8 is supported by the core support member 104 and therefore falls from the grip portion 111. The laminated core 8 can be turned upside down without any problem.

By using the laminated core reversing device 100 of the present embodiment, the vertical direction of the laminated core 8 can be easily inverted while the heavy and large laminated core 8 is firmly gripped by the grip portion 111 in the vertical direction. Therefore, soot adhering to the core surface after welding can be efficiently removed. Further, when the laminated core 8 is turned upside down, it is possible to prevent the unwelded portion (lamination 8a) from being bent or scratched by being caught in the clothes or equipment of the worker. ..

Further, in the laminated core reversing device 100 of the present embodiment, by supporting a part of the outer peripheral surface of the laminated core 8 by a pair of core support members 104 provided on the grip portion 111, the laminated core is supported from the grip portion 111 during rotation. 8 is prevented from falling. As a result, the operator needs to hold down the laminated core 8 during rotation, so that the laminated core 8 can be efficiently inverted.

Further, in the present embodiment, the rotating portion 112 does not rotate unless the laminated core 8 is securely gripped by the gripping portion 111 by the locking mechanism 115. Therefore, it is possible to suppress unintended rotation of the grip portion 111, and it is possible to prevent the laminated core 8 from tilting or falling.

Although the embodiments of the present invention have been described above, the configurations and combinations thereof in the embodiments are examples, and additions, omissions, substitutions, and other modifications of the configurations are made without departing from the spirit of the present invention. Is possible. Further, the present invention is not limited to the embodiments.

For example, in the above-described embodiment, the transport surfaces 101a and 102a of the carry-in portion 101 and the carry-out portion 102 are respectively configured horizontally, but both or one of the transport surfaces 101a and 102a have a core reversing mechanism. It may be configured to incline towards 11. As a result, the laminated core 8 naturally moves down the transport surface to the core reversing mechanism 11, so that the operator does not have to move the laminated core 8. As a result, work efficiency is improved, and more laminated cores 8 can be cleaned.
