Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for automatically and orderly laminating disks successively fed from a punching press or the like.

[0002]

2. Description of the Related Art A conventional disc laminating method is shown in FIGS.
Will be described with reference to. The disk 11 punched by a press (not shown) rides on a belt conveyor 13 below the press and comes out of the press. Disc 1 carried by conveyor 13
1 is stacked on the stacking stand 15 at the tip of the conveyor 13. At this time, in order not to scratch the disc 11,
The operator manually receives the disks 11 discharged from the conveyor 13 and stacks them on the stacking table 15.
The upper surface of the stacking stand 15 is inclined so that the conveyor 13 side is higher and the opposite side is lower, and the pair of stoppers 17 standing perpendicular to the upper surface positions the disc 11.

[0003]

The cost is high because an operator is required to receive and stack the disks ejected from the conveyor. If the disc is heavy, it will be hard work. Further, since the discs are laminated manually, the laminated state is not constant, and the discs are likely to be uneven.

An object of the present invention is to provide an automatic disc laminating apparatus which solves the above problems.

[0005]

Means for Solving the Problem and Its Action The automatic disc laminating apparatus of the present invention is provided with three or more sets of guide units installed at positions where the discs are laminated so as to surround the discs.
Each guide unit is composed of a combination of a side guide that guides the periphery of a falling disc, an impeller that receives the falling disc midway, and a rotation drive unit that rotates and stops the impeller.

The side guides of the respective guide units are arranged vertically so as to surround the falling disk. Further, each impeller is arranged outside the side guide so that the tip of one blade projects inside the side guide. Further, each rotation driving means receives the disk from which the tip of the blade projecting inward of the side guide has dropped from above, and then simultaneously rotates each impeller to drop the disk further downward. The operation of stopping the rotation of the impeller is repeated when the tips of the blades protrude inside the side guides.

The disk discharged from the conveyor or the like falls in the space surrounded by the side guides of this apparatus. The posture of the disc at this time is not constant, but the disc that falls is caught by the tip of the blade of the impeller protruding inside the side guide. As a result, the posture of the disc is adjusted to be constant (usually horizontal). After that, the impeller rotates to drop the discs in the same posture, so that the discs are dropped while the peripheral portions are positioned by the side guides and stacked. Therefore, it becomes possible to stack the disks in an orderly manner without manpower.

The disc automatic laminating apparatus of the present invention is arranged such that the vertically movable pedestal installed below the laminating position of the discs and the vertical position of the pedestal are the uppermost surface of the laminated discs. It is desirable to further include a control unit that controls the height difference between the disc receiving position and the disc receiving position of the impeller to fall within a predetermined range.

If the drop from the position where the impeller receives the disks to the uppermost surface of the already stacked disks is too large,
The posture of the disc may collapse again. If the cradle and the control means as described above are provided, the drop can fall to a predetermined range (the discs separated from the impeller can be dropped to the uppermost surface of the stacked discs without substantially losing their posture). It becomes possible to control within a range), and more stable lamination can be performed.

【Example】

[Embodiment 1] FIGS. 1 and 2 show an embodiment of the present invention. This automatic disc laminating apparatus is provided with three sets of guide units 21 installed at positions where the discs 11 discharged from the belt conveyor 13 are laminated so as to surround the discs 11. One set of them is installed in the central part of the tip of the conveyor 13, and the other two sets are installed at positions 120 ° apart from each other on the opposite sides in the circumferential direction.

Each guide unit 21 has a disc 1 that falls.
It is configured by a combination of a side guide 23 that guides the periphery of 1, an impeller 25 that receives the disc 11 that falls, and a stepping motor 27 that rotates and stops the impeller 25.

Each of the side guides 23 is made of an elongated metal plate and is vertically arranged so as to surround the falling disk 11 with one surface thereof facing inward. One side guide 23 located at the center of the tip of the conveyor 13 has its upper end lower than the upper surface of the conveyor 13, but the other two side guides 23 have their upper ends higher than the upper surface of the conveyor 13. . This is to prevent the disc 11 discharged from the conveyor 13 from jumping out of the apparatus. The upper portion of the side guide 23 is bent outward so that the disc 11 can be easily received. A window 29 is formed at the same height in the intermediate portion in the vertical direction of each side guide 23.

Each impeller 25 has four blades 25a attached at 90 ° intervals around the central axis. The impeller 25 is arranged outside the side guide 23, but
One of the blades 25a has a side guide 2 at its tip.
It projects through the window 29 of No. 3 inside the side guide 23. In this state, the impeller 25 is attached to the rotating shaft of the stepping motor 27, and the stepping motor 27 is attached to the side guide 23. The central axes of the three impellers 25 and the stepping motor 27 are all at the same height.

The stepping motor 27 is normally stopped in a state where the blades 25a protruding inside the side guide 23 are horizontal, and when a signal from the rotation control device 31 is input, the stepping motor 27 rotates 90 ° and then stops again. It is like this.
When the disc detector 33 installed above the conveyor 13 detects the disc 11, the rotation control device 31 outputs a signal for rotating the stepping motor 27 by 90 ° after a certain period of time.

The three sets of guide units 21 configured as described above are attached to the lower surface of the table 35. The table 35 has a hole 37 which is sufficiently larger than the disc 11 in the central portion. The upper portion of the side guide 23 penetrates the hole 37 of the table 35. While each guide unit 21 is attached to the lower surface of the table 35, the radial position (that is, the distance from the central axis of the position where the circular plates 11 are stacked (C in FIG. 1) to the inner surface of the side guide 23) can be adjusted. It is like this. This is because the position of the guide unit 21 is adjusted according to the size of the discs so that the discs of various sizes can be stacked.

A pressing roller 39 is installed above the turn roller 13a of the conveyor 13 to prevent the disc 11 discharged from the conveyor 13 from being bent forward. The pressing roller 39 is normally in contact with the conveyor 13, but is pushed up by the disc 11 when passing through the disc. The pressing force of the pressing roller 39 is set according to the diameter, weight, etc. of the disc 11. This pressing force can be arbitrarily set by changing the supply pressure to the air cylinder 41.

This disc automatic laminating apparatus has the disc 11
It is provided with a pedestal 43 for mounting. The pedestal 43 can be moved up and down by an elevating device 45. Further, this device is provided with a level detector 47 at a certain height below the impeller 25, which detects the level of the uppermost surface of the disk 11 stacked on the pedestal 43. This level detector 47
When it is detected that the uppermost surface of the disc 11 is higher than the position of the level detector 47, the lifting control device 49 causes the lifting device 4 to move.
A signal is sent to 5 to lower the pedestal 43. Further, when the level detector 47 detects that the uppermost surface of the disk 11 is slightly lower than the position of the level detector 47, the lifting control device 49 sends a signal to the lifting device 45 to lower the pedestal 43. Stop. Discs 11 stacked in this way
The top surface of is always kept at a constant height.

The position of the level detector 47 is set to a height at which the discs falling from the impeller 25 can reach the uppermost surface of the already laminated discs 11 while remaining substantially horizontal.

The automatic disk laminating apparatus of this embodiment has the above-mentioned structure. Next, the operation of this device will be described. The disc 11 sent by the conveyor 13 is detected by the disc detector 33.
Is detected, the rotation control device 31 starts measuring time from that point. At this point, the impeller 25 is stopped in a state in which the tip of one blade 25a is horizontally projected inside the side guide 23. The detected disc 11 is discharged from the conveyor 13 under the pressing roller 39, hits the upper portions of the two side guides 23 on the opposite side, and then falls into the space surrounded by the three side guides 23. . At this time, the posture of the disc 11 is not constant, but the disc 11 that falls is received by the tip of the blade 23a protruding inside the side guide 23 in the middle. By this, the posture of the disc 11 is adjusted horizontally.

Since the time from the detection of the disk 11 by the disk detector 33 to the reception of the disk 11 by the impeller 25 is substantially constant, the rotation control device 31 will be The three stepping motors 27 are simultaneously rotated 90 °. Then the disk 1 that was held horizontally
1 falls as it is and is laminated on the already laminated discs 11. At this time, the disc 11 is moved to the side guide 23.
Since the position is regulated by, it does not shift laterally. Further, the 90 ° rotation of the stepping motor 27 causes the tip of the next blade 25a to project inside the side guide 23, and is ready to receive the next disk.

On the other hand, when the next disk 11 is stacked on the disk 11 that has already been stacked, the level detector 47 detects it, and the lift control device 49 sends a signal to the lift device 45. The pedestal 43 is lowered by the thickness of one disk.

In this apparatus, the disks 11 can be stacked in an orderly manner by repeating the above operation.

[Embodiment 2] FIGS. 3 to 5 show a preferred embodiment of the guide unit 21 which is the main part of the apparatus of the present invention. Only one set of guide units is shown here,
This guide unit also has three sets (or four) as in the first embodiment.
Group) are combined to form an automatic disc laminating apparatus. Similar to the first embodiment, reference numeral 23 is a side guide, 25 is an impeller, and 27 is a stepping motor.

The first characteristic of this guide unit 21 is that
The tip of the blade 25a of the impeller 25 is bifurcated as shown in FIG. 4, and the side guide 23 is vertically formed with two windows 29 into which the tip of the bifurcation is inserted. That is. The guide center 23a is located between the two windows 29.
Has become. The reason for such a structure is as follows.

Since the side guide 23 is composed of a flat metal plate, the periphery of the disc is mainly guided by a very narrow portion at the center in the width direction (this portion is referred to as a guide center). Therefore, when the region including the guide center is a window, when the disc 11 is received by the impeller 25, the gap between the periphery of the disc and the side guide becomes large, and the position of the disc is slightly displaced. There is. As a result, when the impeller 25 rotates to drop the disc 11, the disc may hit the lower edge of the window and lose its posture. In order to eliminate this, the present embodiment has a structure in which the tip end portion of the blade 25a is bifurcated and the guide center 23a of the side guide 23 is inserted therebetween. With this arrangement, when the disk 11 is received by the impeller 25, the disk 1
Since 1 is accurately positioned by the guide center 23a, there is no risk of losing its posture even when it is subsequently dropped.

The side guide 23 does not necessarily have to be made of a metal plate, but can be made of, for example, a thin metal rod. In this case, since the metal rod is also the guide center of the side guide, the bifurcated tips of the blades of the impeller project inside the side guide from both sides of the rod-shaped side guide, not through the window.

The second characteristic of the guide unit 21 of this embodiment is that the rubber plate 51 is attached to the surface of the blade 25a of the impeller 25 on the side for receiving the disk 11. This is to prevent the disc 11 from being scratched.

The third characteristic of the guide unit 21 of this embodiment is that when the impeller 25 is stopped with the tip of one blade 25a protruding inside the side guide 23, That is, a hook 53 that hooks on one blade 25a to prevent rotation of the impeller 25 is provided (see FIG. 3, not shown in FIG. 4). The hook 53 can be moved forward and backward by an actuator 55 such as a solenoid.
When the impeller 25 starts rotating by 7, the impeller 25 is allowed to rotate, and the impeller 25 moves forward until the impeller 25 rotates by 90 ° to hook the next impeller 25a. The reason why the hook 53 is provided is as follows.

That is, the impeller 25 is the disc 11 on which it falls.
I am shocked when I catch it. This impact increases as the disc weight increases, and the stepping motor 27
In some cases, it may not be possible to support only the holding power of. If the impact is too great to support the stepping motor 27, the impeller 25 will rotate and cannot receive the discs, so that normal stacking operation cannot be performed. By providing the hook 53 as described above, such an accident can be prevented. In order to prevent the impeller from rotating due to impact, it is possible to use a motor with a brake instead of the stepping motor.

[Third Embodiment] FIG. 6 shows another embodiment of the present invention. In this embodiment, in order to prevent the circular plate 11 discharged from the conveyor 13 from being bent forward, the pressing roller 39 is installed slightly before the turn roller 13a of the conveyor 13. Since the other points are the same as those in the first embodiment, the same parts are designated by the same reference numerals and the description thereof will be omitted.

[Embodiment 4] FIGS. 7A and 7B show still another embodiment of the present invention. In this embodiment, the conveyor 13
A buffer end stopper 57 is installed at a position where the disk 11 emitted from the disk collides with the disk 11, so that the collision energy of the disk 11 is absorbed. Since the other points are the same as those in the first embodiment, the same parts are designated by the same reference numerals and the description thereof will be omitted.

[Embodiment 5] FIGS. 8A and 8B show still another embodiment of the present invention. In this embodiment, the conveyor 13
The auxiliary impeller 59 is installed while the disk 11 discharged from the disk 11 falls to the impeller 25, so that the disk 11 is prevented from swaying. The material of the auxiliary impeller 59 is preferably one that does not scratch the disc 11, and rubber or the like is preferable. Since the other points are the same as those in the first embodiment, the same parts are designated by the same reference numerals and the description thereof will be omitted.

The above are the embodiments of the present invention, and the present invention is not limited to these embodiments. For example, the guide units 21 can be installed at four or five places instead of three places. In addition, the blade of the impeller 25 is 4
The number of sheets may be three to one instead of one. In the case of 3 pieces, the impeller is 120 ° each, and in the case of 2 pieces, it is 180 °
In the case of one sheet each, it may be rotated by 360 °.
