Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a thin-leaf-plate take-out device configured to supply thin-leaf plates in, for example, an automatic assembling apparatus.

[0002]

2. Description of the Related Art In an apparatus for automatically assembling a finished product using a thin sheet as a part, there is a storage section for accumulating and storing the above thin sheet, from which a sheet is taken out and supplied one by one according to an instruction signal. It is like this.

For example, as shown in FIG.
A take-out device that doubles as a storage unit is used. Reference numeral 1 denotes a case body whose upper end has an opening 1a with all the upper surface walls removed, and the bottom has an opening 1c which leaves bottom walls 1b and 1b on both sides and opens only in the central part.

A large number of thin leaf plates 2, ... Are laminated on the bottom walls 1b, 1b of the case body 1, and are initially accommodated within a range not exceeding the upper end opening 1a. Lower end opening 1 of case body 1
A lifter 3 as a support is inserted into the case body 1 from c to support a large number of thin leaf plates 2, ... In a laminated state. The lifter 3 is connected to a drive source (not shown) and can move up and down. In response to the take-out signal, it rises by a predetermined amount, and in a state where all the thin leaf plates 2 ... In the case body 1 have been taken out, it falls again below the bottom wall 1b, 1b of the case body 1. There is.

On the other hand, the suction pad 4, which is a suction body, is inserted from the upper end opening 1a of the case body 1 in response to a take-out signal. The suction pad 4 is connected to a drive source (not shown) and can be moved up and down, and is also connected to a vacuum source so that the thin leaf plate 2 can be vacuum-sucked at its lower end opening.

Then, the suction pad 4 descends and is inserted into the inside of the case body 1 through the upper end opening 1a, abuts against the uppermost thin leaf plate 2 of the laminated thin leaf plates 2, ... Take it out of the case body 1. The stacking dimension decreases as it is taken out. In order to keep the pickup position of the suction pad 4 constant, the lifter 3 is driven upward by an amount corresponding to the pickup.

[0007]

The thin leaf plate 2 to be taken out has a smooth surface in many cases, and therefore static electricity and friction are likely to occur between the thin leaf plates 2 located above and below. . Alternatively, the thin leaf plate 2 itself may have a certain degree of adhesiveness, and in any case, the thin leaf plate 2 easily adheres to other thin leaf plates 2.

In the state where the suction pad 4 is in contact with the uppermost thin leaf plate 2 and is vacuum sucked and raised, as shown in the figure, the next lower leaflet plate 2 is in close contact with the case body 1 for the above reason. May be taken from within. That is, two sheets are taken out and supplied. In some cases, simultaneous removal of three or more sheets may occur.

The conventional apparatus is not provided with a means for restricting the taking-out of a plurality of sheets as described above, and the apparatus can be recognized only when it reaches a predetermined conveyance site. Alternatively, there is a possibility that the close contact state may not be maintained during the taking-out and conveyance, and the thin sheets 2 may fall around the apparatus, which may cause scattering.

It is impossible to change the characteristics of the thin leaf plate 2 as the object to be taken out, and therefore it is not possible to prevent the adsorption of a plurality of sheets by the adsorption pad 4, but during taking out in the case body 1, some It is indispensable in this type of device to regulate the taking out of a plurality of sheets.

The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to reliably prevent a plurality of thin leaf plates from being taken out from the case body to improve reliability. To provide a take-out device.

[0012]

In order to achieve the above object, a thin-leaf plate take-out device of the present invention comprises a case body having both ends open, and an ascending / descending body from the end side opening of the case body. A support body that is freely inserted and supports a plurality of thin leaf plates in a stacked state, and a laminated thin leaf board that is vertically inserted into the case body from the opening on the other end side of the case body and is supported by the support body. A take-out body that vacuum-adsorbs the upper thin sheet to the outside of the case body, a separation claw that is provided at the other end of the case body and projects toward the inside of the case body, and a other end of the case body. And a swinging lever that is rotatably supported at a position opposite to the separating claw, and a swinging lever that is pivotally supported by the end of the swinging lever, and a part of its peripheral surface protrudes toward the inside of the case body. , The separation dimension between the separation claw end and its peripheral surface is calculated from the width dimension of the thin plate. Characterized by comprising a roller which is formed into small. The take-out body is an adsorbent body that comes into contact with the uppermost thin leaf plate of the laminated thin leaf plates supported by the support body, vacuum-adsorbs it, and takes it out of the case body.

[0013]

[Function] Even if the adsorbent tries to pass through the opening of the case body while adsorbing a plurality of thin leaf plates due to the influence of friction or static electricity, both side edges of the thin leaf plates are provided with separation claws provided here. And slide on the roller.

All of the plurality of thin leaf plates are curved and deformed, the contact portions of the thin leaf plates are displaced from each other, air enters, and the thin leaf plates adhering thereto are separated from the thin leaf plates that are vacuum-adsorbed, leading to a drop. .

On the other hand, the sliding contact force of the roller is less than the suction force of the adsorbent, and the thin leaf plate adsorbed directly to the adsorbent passes through as it is. However, for the thin leaf plate that is in close contact with the thin leaf plate, the sliding contact force of the roller exceeds the close contact force, and the thin leaf plate is easily peeled off. That is, the removal of a plurality of thin leaves is regulated.

[0016]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows the take-out device in a state where the taking-out of a plurality of sheets is restricted. FIG. 2 shows the details of a newly provided plural-sheet take-out restricting means in which the supporting body 3 which may be the same as the conventional structure and the adsorbing body 4 are omitted.

In the figure, 1A is a case body. The case body 1A includes an upper opening 1a and bottom walls 1b and 1b on both sides.
And has a lower end opening 1c. First, a large number of thin leaf plates 2, ... Are stacked on the bottom walls 1b, 1b of the case body 1A and accommodated within a range not exceeding the upper end opening 1a.

Here, one side wall of the case body 1A has a side surface opening 1d which opens in the vertical direction, and the thin leaf plate 2 from the inside of the case body 1A by a sensor (not shown).
The ejection can be detected.

From the lower end opening 1a of the case body 1A, into the case body 1A, a lifter 3 which is connected to a drive source (not shown) and can be raised and lowered is inserted, and a large number of thin leaf plates 2 are laminated. Support in the state. In response to the takeout signal,
When the thin plate 2 in the case body 1A is lifted up by a predetermined amount and the bottom wall 1b of the case body 1A,
Falling below 1b is exactly the same as the conventional one.

On the other hand, the upper end opening 1a of the case body 1A
From this, a suction pad 4, which is a suction member, which is connected to a drive source (not shown) and can be moved up and down and communicates with the vacuum source, is inserted. The thin leaf plate 2 can be lowered in accordance with the take-out signal, and the thin leaf plate 2 can be vacuum-adsorbed to the lower end opening portion and raised. The suction pad 4 may be the same as the conventional one.

A side wall 1e of the case 1A corresponding to the width direction of the thin leaf plate 2 housed in the case body 1A and the side wall 1e.
A plurality of sheets ejection preventing means S is provided at the upper end of the side wall 1f facing e.

That is, the upper end of the side wall 1e of the case body 1A is a separation claw 10 formed by cutting and raising a part of the side wall 1e inside the case body 1A. The upper end of the other side wall 1f is notched, and one piece 11a of the support metal fitting 11 bent in a plane L shape is attached and fixed to this side, and the other piece 11b faces the notch. .

A pivot pin 12 is provided on this piece 11b, and a swing lever 14 having a roller 13 mounted on the upper end side is pivotally supported so as to be rotatable. Further, a coil portion of a torsion spring 15 is wound around the pivot pin 12, one end of the spring abuts on a piece 11a of the support fitting 11, and the other end abuts on the rocking lever 14. Contact. The elastic force of the torsion spring 15 acts on the swing lever 14 to urge at least a part of the peripheral surface of the roller 13 into the case body 1A.

Therefore, the rollers 13 facing each other from the tip edge of the separating claw 10 provided at the upper end of the case body 1A are larger than the width dimension of the thin leaf plate 2 housed in the case body 1A.
The space dimension to the peripheral surface is inevitably small.

Then, the suction pad 4 descends, is inserted into the inside from the upper end opening 1a of the case body 1A, contacts the uppermost thin leaf plate 2 of the laminated thin leaf plates 2, ... To rise.

From the setting condition that the interval between the separating claw 10 and the roller 13 provided at the upper end of the case body 1A and facing each other is smaller than the width dimension of the thin leaf plate 2, the thin leaf sucked by the suction pad 4 is adsorbed. At the position where the plate 2 passes through the upper opening 1a of the case body 1A, the both side ends must be separated by the separating claw 10 and the roller 13.
Sliding on the peripheral surface. Since the suction pad 4 rises, the thin leaf plate 2 is curved and deformed in the shape of a lower chord.

However, the suction force of the thin leaf plate 2 of the suction pad 4 is due to the deformation caused by the separation claw 10 being hooked and the roller 13.
It is large enough to exceed the sliding contact force of. In other words, the torsion spring 15 causes the roller 13 pivotally supported by the swing lever 14 to rotate.
On the other hand, the elastic force is applied to the extent that the thin leaf plate 2 is not separated from the suction pad 4.

Therefore, the thin leaf plate 2 adsorbed here rises over the separating claw 10 and the roller 13 while being deformed. Then, it returns to the original flat plate shape and is taken out at a predetermined position.

The thin leaf plates 2 to be taken out have a smooth surface and, in some cases, have a certain degree of adhesiveness, and static electricity and friction are likely to occur between the upper and lower thin leaf plates 2. There is a case where the thin leaf plate 2 of the next lower level is lifted while being in close contact with the thin leaf plate 2 that is sucked by the suction pad 4.

That is, a plurality of sheets such as two sheets or three sheets are about to be taken out. Also at this time, the separation claw 10 and the roller 13 which face each other are slidably brought into contact with each other at a position where they pass through the upper opening 1a of the case body 1A.

As described above, both the thin leaf plates 2 and 2 are curved and deformed according to the setting conditions of the width dimension of the thin leaf plate 2 and the spacing dimension from the separating claw 10 to the roller 13. In this state, a partial displacement occurs between the thin leaf plates 2 and 2 that are in close contact with each other, and a large gap is generated particularly in the central portion of each other.

For the thin leaf plate 2 that is in close contact with the thin leaf plate 2 that is directly adsorbed to the adsorption pad 4, the occurrence of a gap is a factor that leads to a peeling action from the thin leaf plate 2 that was in close contact. Further, since the sliding contact force of the roller 13 with respect to the thin leaf plate 2 is less than the suction force of the suction pad 4, the thin leaf plate 2 directly sucked by the suction pad 4 is between the separation claw 10 and the roller 13. Pass through.

However, for the thin leaf plate 2 on the close contact side, the sliding contact force received from the separating claw 10 and the roller 13 exceeds the close contact force, so that it is inevitably peeled off from the thin leaf plate 2 that has been in close contact until then. It falls into the case body 1A.

Further, as shown in FIG. 3, the fact that the clearance H is set between the roller 13 and the tip edge of the separating claw 10 also has an effect, so that only the thin leaf plate 2 sucked by the suction pad 4 is surely affected. The thin leaf plate 2 that is taken out of the sheet and is closely attached to the sheet is regulated.

The bending angle of the separating claw 10, the number of rollers 13, the distance between the separating claw 10 and the roller 13, the elastic force of the torsion spring 15, the lever ratio of the rocking lever 14, etc. By adjusting, the conditions applicable to the material, plate thickness, smoothness, and degree of deformation of the thin leaf plate 2 can be obtained, and reliable removal of a plurality of sheets is always regulated. In addition, it goes without saying that various modifications can be made without departing from the scope of the present invention.

[0036]

As described above, according to the present invention, the separation claw protruding toward the inside of the case is provided at the upper end of one side wall of the case, and the swing lever is provided so as to face the separation claw. A pivotally supported roller was provided, and a part of the peripheral surface of the roller was made to project inward from the inner peripheral wall of the case body, and the distance between the separation claw and the roller peripheral surface was made smaller than the width dimension of the thin plate. Therefore, even if the adsorbent adsorbs a plurality of thin leaf plates at the same time in the case body, the separation claw and the roller can reliably prevent the plurality of thin sheet plates from being taken out from the case body, thereby improving reliability. Moreover, the structure is relatively simple, and the cost is not adversely affected.
