Description

[Detailed description of the invention] This invention is used in a device for stripping laminated iron plates, more specifically, in a loading device that sucks up laminated iron plates one by one from the top one using a suction cup and transports them to a pressing process, etc. the end of 2
This relates to a device for stripping off the first iron plate.

Conventionally, in the above-mentioned loading device, when the laminated iron plates are sucked up one by one from the top one using a suction cup, the second laminated iron plate comes into close contact with the top laminated iron plate and is suddenly pulled up and dropped. This necessitated the labor-intensive work of manually returning the fallen laminated iron plates to their original positions each time, resulting in a disadvantage that work efficiency was unavoidably reduced.

This idea was made in order to improve the above-mentioned drawbacks. When picking up the topmost laminated iron plate, the edge of the topmost laminated iron plate is peeled off from the second laminated iron plate, and the uppermost laminated iron plate is removed. The purpose of the present invention is to provide a laminated iron plate stripping device that steadily sucks off only the iron plate.

An embodiment of this invention will be described below based on the drawings.

FIG. 1 shows a perspective view of the loading device. In this figure, 10 is a fixed base, and this fixed base 10
A pair of left and right rails 11, 11 provided on the top of the
A traveling base 14 is provided which is driven by a motor 12 and travels in the direction of an arrow 13. Reference numeral 15 denotes an up-and-down table disposed below the carriage 14, which is movable up and down on the carriage 14 by means of a plurality of guide rods 16 projecting upward. Reference numeral 17 denotes a lifting device for the vertical table 15, in which a sprocket 20 is provided on a shaft 19 which rotates forward and reverse by a motor 18, and a chain 21 meshed with this sprocket 20.
The above-mentioned upper and lower stands 15 are suspended from one end, and a weight 22 for preventing the chain from coming off is suspended from the other end. A plurality of suction cups 24 that stick to the laminated iron plates 23 are arranged at the lower part of the upper and lower tables 15, and the support shafts 25 of each suction cup 24 are attached to the upper and lower tables 15. 2
Reference numerals 6 and 26 are frames protruding from the left and right sides of the upper and lower tables 15, and each frame 26 has a laminated iron plate 23 at the top.
A stripping device 27 is provided for stripping off both ends 23b of a. FIG. 2 shows a perspective view of the stripping device 27, and FIG. 3 shows a partially cutaway sectional view of the same device.

In the stripping device 27, a set of two guide rods 29 protruding from the base 28,
A block 30, which moves up and down along 29, is supported by the lower end of a piston rod 33 of a cylinder device 32, which strokes in the direction of arrow 31 in FIG. 3, that is, in the up and down direction. As shown in FIG. 4, the base 34 of the cylinder device 32 is connected to the guide rod 29,
The guide rods 29 are provided in upper small diameter portions 35, 35 of the guide rods 29 so as to be movable up and down, and are pressed and held by springs 36, 36 against the step portions 37, 37 of the guide rods 29, 29. The block 30 also includes a cylinder device 39 that strokes in the direction of arrow 38 in FIG.
A sliding member 41 connected to the tip of the locking arm 41 and sliding in the direction of the arrow 38 is supported, and the upper end of the locking arm 42 is supported by a pin 43 so as to be swingable in the direction of the arrow 44. . A blade body 46 is detachably provided on the lower end side of the locking arm 42 and has a saw blade-shaped locking portion 45 that locks onto the end 23b of the uppermost laminated iron plate 23a. A portion near the upper end of the locking arm 42 is loosely fitted into a through hole 47 provided in the sliding member 41, and in the loosely fitting portion, the sliding member 41 is connected to the locking arm 42 via a roller 48 for reducing frictional resistance. By coming into contact with this, the saw blade-like locking portion 45 is moved from the locking position of the uppermost laminated iron plate 23a to the release position. Moreover, between the locking arm 42 and the sliding member 41,
A spring 49 is provided that biases the locking arm 42 toward the roller 48 side. A hole 50 passing through the base 28 and the frame 26 downward is provided in the lower part of the block 30, and a support shaft 52 of a suction cup 51 is fitted into this hole 50 so as to be able to slide vertically with a certain amount of play S. ing. That is,
When the block 30 rises by the above-mentioned play S from the state in which the suction cup 24 on the vertical stand 15 side and the suction cup 51 on the frame 26 side are attracted to the uppermost laminated iron plate 23a, the upper end of the support shaft 52 of the suction cup 51 The upper edge portion 54 of the hole 50 is adapted to engage with a flange 53 formed in the portion. In addition, in Figure 1, 5
5 is a suction cup that responds to the deflection of the end portion 23b of the uppermost laminated iron plate 23a.

Next, the operation of the above configuration will be described. First, the motor 18 of the lifting device 17 is driven to lower the upper and lower tables 15, and the suction cups 24, 51, and 55 are brought into contact with and attracted to the upper surface of the uppermost laminated iron plate 23a (see FIG. 5a). Then, the piston rod 40 of the cylinder device 39 is moved backward, and the sliding member 41 is moved to the third position.
It is moved in the direction of arrow 38a in the figure. This results in
The locking arm 42 rotates in the direction of the arrow 44a, and the saw-edge locking portion 45 engages with the end 23b of the uppermost laminated iron plate 23a. At this time of engagement, the spring 49
As a result, the impact acting on the saw-blade-shaped locking portion 45 is alleviated, and damage to the saw-blade-shaped locking portion 45 is prevented.
After that, the piston rod 3 of the cylinder device 32
Pull in 3 to raise block 30. At this time, the saw blade-like locking portion 45 rises by the play S before the suction cup 51 rises, and the end 23b of the uppermost laminated iron plate 23a
(see figure b) is peeled off from 23c. When the above-mentioned play S disappears and the upper edge 54 of the hole 50 of the block 30 comes into contact with the collar 53 of the support shaft 52 of the suction cup 51, the suction cup 51 also rises and the uppermost laminated iron plate 23a An even larger portion of the end 23b is stripped off (see Figure 5c).

When the block 30 rises to the maximum limit and the above stripping operation is completed, the upper and lower tables 15 are raised by the reverse drive of the motor 18, and the uppermost laminated iron plate 23a is pulled up. At this time, the uppermost laminated iron plate 23a
The end portion 23b of the second laminated iron plate 23c is peeled off to a larger extent than the second laminated iron plate 23c.
c adheres to the uppermost laminated iron plate 23a and is not pulled up, and only the uppermost laminated iron plate 23a is steadily sucked upward. After sucking up the uppermost laminated iron plate 23a, the piston rod 33 of the cylinder device 32, that is, the block 30 is lowered to set the suction cup 51 at the same height as the suction cup 24, and the sucked laminated iron plate 23a is returned to a flat plate. When the block 30 is lowered, when the block 30 comes into contact with the base 28 and a reaction force is applied to the cylinder device 32, this reaction force is absorbed by the spring 36, thereby preventing damage to the cylinder device 32.
Next, the carriage 14 is moved to a predetermined position, and at that position, the piston rod 40 of the cylinder device 39 is projected to advance the sliding member 41 in the direction of arrow 38b. In this case, the locking arm 42 is
is pushed and rotated in the direction of the arrow 44b, and the saw-blade-like locking portion 45 separates from the end portion 23b of the laminated iron plate 23a. After that, the suction force of each suction cup 24, 51, 55 is released, and the laminated iron plate 23a is dropped.

As described above, according to this invention, when picking up the uppermost laminated iron plate with a suction cup, the end of the uppermost laminated iron plate is peeled off from the second laminated iron plate, and only the uppermost laminated iron plate is removed. Provided is a laminated iron plate stripping device that steadily sucks off.
