Abstract

PURPOSE:To cut out a group of piled plates from a storing part in which many particularly thin plates of same shape are piled not by the decided number of sheets but by the decide thickness. CONSTITUTION:In a device in which a slider 3 is passed together with thin plates from the underside of a storing part 1 to a thickness setting part 2 so as to cut out a group of the thin plates of decided thickness, by providing the thickness setting part 2 on one side of the storing part in which the thin plates are piled, and providing the slider 3 for cutting out on the other side, an inclined face 5 is provided on the upper part of the slider 3, and an adjusting piece 6 movable pack and forth along the inclined face 5 is positioned always in a position decided by a spring 9 and the like, namely, in sach a position that the upper end angle part 6a of the adjusting piece 6 passes the underside or the lower end angle part 2a of the thickness settig part nearer by the thickness of one piled plate. Hereby, even if there is a random plate to obstruct the movement of the adjusting piece during operation, the adjusting piece is dislocated to the lower end along the plate thickness face, returned as soon as it is released and pushes out the plates through the thickness setting part, and hence the plates can be surely cut out in the range of the thickness.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for cutting a group of plates having a constant thickness, rather than a constant number, from a storage part in which a plurality of thin plates having the same shape are stacked.

[0002]

2. Description of the Related Art For example, as shown in FIG. 4, an E-shaped (see FIG. A) or I-shaped (see FIG. B) iron core or a motor core of a transformer used in electric equipment is not a fixed number of stacked sheets, It is required to adjust the number of iron plates so that the thickness is constant.

In such a case, conventionally, an apparatus as shown in FIG. 5 can be considered. The figure is a cross-sectional view of the apparatus. For example, a storage unit 1 in which a large number of thin iron plates are stacked is located substantially in the center of the table 10, and the distance from the table 10 corresponds to the thickness dimension of a group 4 of stacked plates having a required thickness. As described above, the thickness setting unit 2 is located at one lower end of the storage unit 1. On the other hand, a slider 3 which slides on the table 10 by a cylinder 11 is provided.

The lower end corner portion 2a of the thickness setting portion 2 and the slider 3
The gap between the upper end corner portion 3a and the upper end corner portion 3a is smaller than the thickness of one sheet to be stacked, and the slider 3 can pass between the table 10 and the thickness setting portion 2.

[0005]

With such a structure, the table 10 is provided in order to obtain the group 4 of stacked plates having a required thickness.
From the slider 3 to the stacked plates from the inside to the reservoir 1
When pushed with, the stray plate 4a (see FIG. 6A) is prevented from moving by the lower end corner 2a. On the other hand, the upper corner 3a of the slider 3 may pass below the plate thickness of the stray plate 4a, but may interfere with the middle of the plate thickness.

Generally, since the thickness of one plate is larger than that between the stacked plates, the upper end corner portion 3a interferes with the plates in most cases. Then, the stray plate 4a whose movement is blocked by the lower end corner portion 2a is strongly pressed by the slider 3 and is deformed and bent as shown in FIG. 6 (B). At that point, the desired stack 4 of stacks cannot be obtained and its purpose cannot be achieved.

Therefore, the problem to be solved by the present invention is that the last thin plate (stray plate) constituting a required thickness.
It is an object of the present invention to provide a device for automatically discriminating whether to reliably cut out or leave without deforming.

[0008]

In order to solve the above problems, the present invention will be described with reference to FIG. 1 corresponding to an embodiment of the present invention. An inclined surface 5 is provided above the slider 3 with respect to the sliding direction of the slider 3, and an adjusting top 6 which can be moved back and forth along the inclined surface 5 is always held at a fixed position by a biasing means such as a spring 9. Install as described. The fixed position means that the gap formed between the lower end corner portion 2a of the thickness setting portion 2 and the upper end corner portion 6a of the adjustment top 6 held by the slider 3 is smaller than the thickness of one plate to be cut out. The near lower side means a position where the upper end corner portion 6a of the adjusting top 6 passes.

According to the second aspect of the invention, the adjusting top 6 is not formed as a part of the slider 3, but the adjusting top 6 is incorporated in a part of the thickness setting portion 2 as shown in FIG. An inclined surface 5 is provided below the thickness setting portion 2 on the opposite side of the slider 3 with respect to the sliding direction of the slider 3, and an adjusting top 6 which can move back and forth along the inclined surface 5 is provided with a spring 9 or the like. It is attached so that it is always held in a fixed position by the biasing means.
In addition, the fixed position means that the lower end corner portion 6b of the adjusting top 6 is positioned above the upper end corner portion 3a of the slider 3 which is closer to the thickness of the stacked plates.

[0010]

In FIG. 1, first, the cylinder 11 is operated to move the sliders 3 and the adjusting top 6 from a plurality of stacked plates.
When cutting out the group 4 of stacked plates having a required thickness by, it is assumed that a stray plate 4a which is blocked by the lower end corner portion 2a of the thickness setting portion 2 is generated (see FIG. 2A). At this time, the upper end corner portion 6a of the adjusting top 6 interferes with the plate surface of the stray plate 4a, and the slider 3 moves but the adjusting top 6 is prevented from moving. However, when it goes further, the return spring 9 is compressed and retracts relatively to the slider 3. Therefore, when the adjusting top 6 moves backward along the slope 5, the upper end corner portion 6a
Shifts the plate thickness surface of the stray plate 4a to the lower side, and finally the interference is released, so that the stray plate 4a remains in the storage portion 1 and the adjusting top 6 is advanced on the slope by the return spring 9 to move the slider. After returning to the position of 3 (constant position), the group of stacked plates 4 is pushed out to the left while aligning with each other.

However, in the case of FIG. 3, the stray plate is pushed by the slider 3, but the adjusting top 6 shifts upward to cancel the interference,
It is surely pushed out. Therefore, the thickness of each of the obtained stacks of plates is within the range of the plate thickness of one plate.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the device of the present invention will be described below.

FIG. 1 is a cross-sectional view showing an embodiment of the device of the present invention, in which 1 is a storage part in which a large number of plates having the same shape are stacked, and one side of the lower part corresponds to a required thickness. And a slider 3 for cutting out the stacked plates is provided on the other side. The slider 3 is positioned so that it can pass through the thickness setting section 2 so that a group 4 of plates stacked to a required thickness can be obtained from the lower side of the storage section 1 by a plurality of plates. In the device, the slider 3
An inclined surface 5 is provided on the upper part of the table in the sliding direction, and an adjusting top 6 that can move along the inclined surface 5 is attached.

Further, the adjusting top 6 has a guide groove 8 and engages with a guide pin 7 provided on the slider 3.
Further, there is a return spring 9 behind the adjusting top 6, which cooperates with the guide groove 8 and the guide pin 7 to hold the adjusting top 6 at a fixed position to be described later and slide it on the table 10 by the cylinder 11. I am doing it.

The fixed position means that when the slider 3 and the adjusting top 6 pass under the thickness setting portion 2, the upper end corner portion 6a of the adjusting top 6 and the lower end corner portion 2a of the thickness setting portion 2. The position is such that the gap formed between the two is smaller than the thickness of one stacked plate.

In order to ensure that the adjusting top 6 moves along the inclined surface, the guide groove 8 is an elongated hole parallel to the inclined surface 5, and its position is the same as the inclined surface 5 and the axis of the return spring 9. Be located between.

The operation of the present invention configured as described above will be described with reference to FIGS.

A group 4 of stacked plates having a required thickness is to be cut out from a large number of stacked plates in the storage section 1 by the slider 3 and the adjusting top 6 (see FIG. 1). And
As shown in FIG. 2A, the lower end corner portion 2 a of the thickness setting portion 2
It is assumed that the stray plate 4a that is blocked by is generated.

At this time, if the upper end corner 6a of the adjusting top 6 interferes with the end face of the plate thickness of the stray plate 4a, the slider 3 moves, but the upper end corner 6a is relatively blocked by the stray plate 4a. The adjustment top 6 as a whole moves backward along the inclined surface 5 of the slider 3 while compressing the return spring 9.

When the adjusting top 6 retracts along the inclined surface 5, the upper end corner portion 6a shifts the plate pressure surface of the stray plate 4a which interferes downward. And when it shifts to the lower side,
As shown in FIG. 2 (B), the lower end of the plate pressing surface is reached, the interference between the stray plate 4a and the upper end corner portion 6a is released, and the stray plate 4
a will remain in the storage unit 1.

Then, as shown in FIG. 2 (C), the adjusting frame 6 is moved forward along the inclined surface 5 by the return spring 9.
As shown in FIG. 2D, the slider 4 is returned to its original position (fixed position), and the group 4 of stacked plates cut out in cooperation with each other is aligned and pushed out to the left from the apparatus. .

As described above, the plate group 4 can be cut out while surely leaving the one stray plate 4a which always occurs. Then, the total thickness of the group 4 can be converged within the range of the thickness of one plate than the thickness determined by the thickness setting unit 2, and the object can be achieved.

Next, FIG. 3 is a cross-sectional view showing another embodiment of the present invention, and in order to simplify the explanation, portions having the same operations as in FIG.

In the present embodiment, the adjusting top 6 is not a part of the slider 3 as shown in FIG.
Is part of the reverse of that configuration. In this case, the stray plate 4a is pushed by the slider 3, but the adjustment top 6
Shifts upward, cancels the interference, and is reliably pushed out. The fixed position at which the adjusting top 6 is always held by the return spring 9 means that the lower end corner 6b of the adjusting top 6 passes through the upper end corner 3a of the slider 3 which is closer to the upper side than the thickness of one plate. Position.

As described above, the only difference between FIG. 3 and FIG. 1 is whether the stray plate 4a is cut out or left, and the thickness of the obtained stacking plate group 4 is one plate. Within the plate thickness range of.

[0026]

As described above, the cutting device of the present invention is provided with the adjusting top so as to cut out the stray plate without deforming the last sheet (stray plate) constituting the required thickness. Since it automatically determines whether to leave,
There is a great effect that a group of stacked plates having a required thickness can be surely obtained.
