Abstract

PROBLEM TO BE SOLVED: To reliably and successively separate an easily deformable soft part from a layered body by relatively turning a thin plate part to be separated in both directions to the other thin plate part to be layered with it, separating a contact plane where both are brought into close contact with each other, introducing air between them, and separating them thereafter. SOLUTION: When an actuator 14 is turned, a gasket 1 chucked through a chuck mechanism 11 containing a support plate 5, a guide 3, a claw 6 or the like turns. At this time, in a residual gasket 1 containing the gasket 1, turn is regulated by a guide hole formed in a separating block 4 or a magazine 2, and separation is caused on a contact plane of both gaskets 1. Since a step difference of the guide 3 engages with an inner circumferential surface of the gasket 1 to be separated over the whole circumference of the gasket 1, the gasket 1 is hardly deformed, and the whole gasket 1 can be uniformly and turnably energized, and even if it is put in an easily sticking condition, a reliable and stable separating condition can be produced.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for separating a required number of thin plate components, which are stacked and accommodated in, for example, a magazine.

[0002]

2. Description of the Related Art As a conventional method for separating thin plate parts,
A thin plate component supply device shown in FIG. 12 (Japanese Patent Laid-Open No. 60-6734)
2), a corrugated plate material separating method shown in FIG. 13 (Japanese Patent Laid-Open No. 63-252841), and an oil seal supply device shown in FIG. 14 (Japanese Patent Laid-Open No. 5-277846).

The method for separating the thin plate parts shown in FIG.
A holder 72 in which a thin plate component 71 that can be deformed by air pressure is formed in a concave-convex shape on a suction surface is configured to be able to suck the thin plate component 71 by using vacuum pressure, and the sucked component 7
1 is largely deformed due to unevenness to cause a gap between the stacked layers, while in the storage portion 73, the thin plate component 7
By providing the knurled resistance portion X at the tip of the guide bar 74 that supports 1 in a stacked manner, the end surface of the thin plate component 71 is slightly apt to be caught in the resistance portion X, thereby separating only the component 71 that has been adsorbed. Is the way.

In the method for separating the corrugated plate material shown in FIG. 13, the corrugated plate material 81 having holes is regulated by the work regulating pin 82, the corrugated plate material 81 is held by the magnet chuck 83, and is slid toward the separation block 84. This is a method of separating the corrugated plate material 81. The oil seal separating method shown in FIG.
A plurality of two sheets are stacked and fitted together, and a movable portion 93 having a convex portion Y for press-fitting and fitting the oil seal 92 is provided on the uppermost part of the magazine 91, and lift operation is performed from the convex portion Y to the oil seal. With 92 forced to leave,
This is a method of separating an oil seal in which an oil seal 94 located immediately below the oil seal 92 is press-fitted into the convex portion Y and the oil seal 92 separated from the convex portion Y is held by the finger portions 95.

[0005]

The problems of the conventional method for separating the thin plate components will be described below with reference to the drawings. In the thin plate component supply device shown in FIG. 12, because of its structure, it is possible to deform by air pressure, and since a target is an extremely thin sheet-like work like the component 71, it is difficult to deform due to air pressure or a work that cannot be adsorbed and held by air pressure. In this case, it is difficult to adopt this separation method.

In the method for separating the corrugated plate material shown in FIG. 13, since the corrugated plate material 81 having the holes is regulated by the work regulating pin 82, the corrugated plate material 81 is held by the magnet 83, the corrugated plate material 81 is not provided with holes. Alternatively, it is difficult to adopt this separation method for a work that cannot be held by a magnet or is easily deformed or caught. In the oil seal supply device (Japanese Unexamined Patent Publication No. 5-277846) shown in FIG. 14, a plurality of hollow oil seals 92 are stacked in a vertically standing columnar magazine 91, and the oil seal 92 is press fit into the uppermost part of the magazine 91. Has a movable portion 93 having a convex portion Y formed therein, and is a separation method in which the oil seal 92 is forcibly separated from the convex portion Y by a lift operation.
There is a problem that the work is limited to a seal-like and hollow work that can be press-fitted into the magazine 91. In addition, the movable part 9 is provided on the side of the magazine 91 in which a plurality of magazines are installed.
3 is required, and the structure of the magazine 91 is complicated.

The present invention has been made to solve the above-mentioned various drawbacks, and in particular, a thin plate component separating method and a separating device having a simple structure capable of surely sequentially separating soft components which are easily deformed from a laminated body. The task is to provide.

[0008]

According to the means as set forth in claim 1 or 9, which is adopted to solve the above-mentioned problems, the thin plate component to be separated is face-to-face relative to another thin plate component to be laminated. The joint surfaces of the two are brought into contact with each other by peeling by rotation, an air layer is introduced between them, and then separation is performed.

[0009] By doing so, it is possible to relatively easily peel off the joint surface, which is not easily peeled off by simply pulling in the thickness direction (multilayer direction), by a simple principle, and to simplify the separation of the thin plate parts. You can Particularly, as described in claim 2, this peeling method is effective when the thin plate component has elasticity in the thickness direction such as rubber. That is, the degree of close contact between the joint surfaces due to mutual elastic deformation or the like is great, and it is difficult to separate only the number of thin plate components requiring a pulling force by simply pulling the thin plate components in the thickness direction. On the other hand, since the thin plate component is relatively less deformed in the surface direction (rotational direction) than in the thin thickness direction, for example, the rotation of the thin plate component group to be left is restricted and the thin plate component to be peeled off. When is rotated, the deformation of the two is relatively small, and therefore the strong turning force required for the separation of the two can be concentrated on the contact surface of the two, whereby the separation can be realized.

According to a third aspect of the present invention, which is a preferred embodiment,
In the means of claim 1, further, since the thin plate component on the side (tip side) separated through the attachment is rotated,
The rotating mechanism can be simplified. The means according to claim 4 which is a preferable mode further comprises the means according to claim 1.
Since the attachment is rotated about the rotation axis that is deviated from the center point (two-dimensional center of gravity) of the main surface of the thin plate component,
The area of the sliding joint surface can be gradually reduced, and the rotation can be facilitated. In particular, it is possible to easily separate the thin plate component having the round outer periphery.

According to a fifth aspect, which is a preferable mode,
Further, in the means of claim 1, the thin plate component on the side (tip side) to be separated through the attachment is advanced and retracted to separate the thin plate component, so that the separating mechanism can be simplified. According to a sixth aspect of the present invention, the means according to the sixth aspect is the first aspect.
In addition, among the remaining parts of the laminated body exposed after the rotation, among the remaining parts of the laminated body, there is no hindrance to the rotation of the thin plate part on the side where the exposed main surface of the thinnest plate part closest to the tip is separated. Since the pressure is applied at the position, the separation after the rotation becomes even easier.

According to a seventh aspect of the present invention, which is a preferred embodiment,
In the means of claim 1, further, since the remaining laminated body is displaced in the stacking direction by the thickness of the separated thin plate component on the leading end side, the attachment can always engage with the thin plate component at the same position, The engagement mechanism can be simplified. In a preferred aspect, the means of claim 8 is the method of claim 7.
In the above means, the holder guides the outer peripheral surface or the inner peripheral surface of the laminated body slidably in the thickness direction of the thin plate component, so that the mechanism can be further simplified.

According to a ninth aspect, which is a preferable mode,
In the means according to claim 1, further, by inserting a plate-shaped partition between the separated laminated layers of the thin plate components which are displaced in the rotational direction,
Even if the thin plate parts are easily deformed and adhered to each other, reliable separation is possible. In the mode of inserting a plate-shaped partition, a simple and compact holding system such as a magnet type or vacuum pressure type suction holding type Since the partitioning type separation mechanism is a separate body, the transfer process of the separation mechanism holder can be made compact and lightweight.

According to a preferred aspect of the present invention, the means of claim 1 further comprises a plate-shaped partition inserted between the joint surfaces between the thin plate components which are displaced in the rotational direction, so that peeling is possible. It can be even easier.

(Example 1) An example of the present invention will be described. 1 to 3
Shows a main part of the gasket separating device which is a work, and FIG.
FIG. 3 is a perspective view showing a gasket 1 which is a work. FIG.
Shows the details of the chuck part. FIG. 6 shows a gasket rotating state and a gasket knockout position when the rotation center axis is not offset, and FIG. 7 shows a gasket rotating state and a gasket knockout position when the rotation center axis is offset. FIG. 8 shows a partitioning mechanism of the gasket 1. (Supply Mechanism) A supply mechanism for supplying the gasket 1 in the stacking direction by the lift operation will be described.

As shown in FIG. 4, the gasket 1 has a substantially pentagonal shape having a substantially octagonal hole, and is fitted and stacked in the magazine 2. Magazine 2 is gasket 1
Has a columnar shape formed so as to slidably guide the inside of the gasket, and maintains its posture in the horizontal direction when the gasket 1 is placed and defines its position in the horizontal plane, and also moves the gasket 1 upward. invite.

Gasket 1 stacked in magazine 2
However, when lifted up to the lower surface A of the guide 3 by the lift operation, the clearance β between the lower surface A of the guide 3 described later and the upper surface B of the separation block 4 described later at this time is the gasket 1
Is less than 1.9 sheets, preferably less than 1.5 sheets, and is laminated between the uppermost gasket 1 to be separated and the next gasket immediately below. The next gasket cannot enter the boundary. Of course, the number of gaskets to be peeled off can be plural, and when peeling N gaskets 1 at a time,
The clearance β exceeds the thickness of one gasket 1,
The thickness is less than N + 1 sheets, preferably less than the thickness N + 0.5 sheets.

The separation block 4 is formed with a guide hole having a shape that engages with the outer shape of the gasket 1. The separation block 4 has a base 30 vertically erected as shown in FIG.
The guide hole of the separation block 4 is a necessary condition for separating the gasket 1 by guiding the outer shape of the second gasket or less of the gaskets 1 stacked in the magazine 2 and restricting its rotation. Guide resistance is applied to the gasket 1 other than the gasket to be peeled. (Chuck Mechanism) Next, a chuck mechanism (gasket attaching / detaching mechanism) for rotating the gasket 1 to be peeled will be described with reference to FIG.

This chuck mechanism has a substantially horizontal plate-shaped guide 3 fixed below a substantially horizontal plate-shaped support plate 5 arranged above the magazine 2, and is provided in a radial groove 3 a of the guide 3. The claw 6 is slidably held. Nail 6
The inner end surface 60 is a sliding guide surface having a slope that approaches the axial center downward, and the air cylinder 7 is fixed to the upper surface of the support plate 5. The piston rod 70 of the air cylinder 7 projects downward along the axis M,
At the tip of the piston rod 70, a substantially cylindrical push rod 8 having a tapered outer peripheral surface projects downward along the axis M.

When the air cylinder 7 is driven to move the push rod 8 downward, the five claws 6 are guided by the guide 3, the lower surface of the support plate 5 and the groove 3a to be spread in the radial direction. Claw 6 is supplied gasket 1
The inner peripheral surface 1a of is clamped. A base end of a spring 10 is locked to a cover 9 fixed to the guide 3, and the spring 10 is radially arranged horizontally. Spring 1
The urging end of 0 is pushed into the hole of the pawl 6 and urges the pawl 6 in the centripetal direction. When the energization of the air cylinder 7 is stopped by this, the pawl 6 is urged by the spring 10 and the centripetal direction. And as a result, the chucking of the gasket 1 to be peeled at the uppermost position by the claw 6 is released. Further, the details of the chucking method will be described.

The gasket 1 supplied to the chuck portion 11
The upper corner portion of the inner peripheral surface 1a is fitted and positioned by a minute step 31 formed at the lower end corner portion of the outer peripheral surface of the guide 3. In this state, the push rod 8 is driven by driving the air cylinder 7. When pushed out downward, the claws 6 are respectively spread in the radial direction, and the inner peripheral surface of the gasket 1 is clamped. It is of course possible to adopt a chucking method other than the above, and a chucking method such as a magnet attraction type, a vacuum pressure attraction type, an outer shape clamping type or the like can be employed depending on the form of the work. (Rotation Separation Mechanism) Next, the separation mechanism will be described. Base 3
The front end surface of the air cylinder 2 is directed downward along the axis M.
0 is vertically installed, and a plate 13 is slidably supported on the lower end portion of the piston rod 20a. 30
Reference numeral b denotes a pair of guide cylinders fixed to the unit 12 and holding the posture of the plate 13. A rotary actuator 14 is fixed to the lower surface of the plate 13 along the axis M, and a rotary plate 15 is fixed to a rotary shaft that hangs downward from the rotary actuator 14. 1
Reference numeral 6 denotes a pair of columns that hang down from the rotating plate 15 with the air cylinder 7 interposed therebetween, and the support plate 5 described above is fixed to the lower ends of the columns 16. In this embodiment, as shown in FIG. 6, the shaft center M of the actuator 14 and the work shaft center C are fixed so as to coincide with each other. However, depending on conditions such as the work shape, as shown in FIG. The work axis C may be fixed at a position offset from the axis M. When offsetting, the contact area between the gasket 1 and the next gasket 1 to be peeled off with rotation is reduced, and peeling is facilitated. In particular, this effect is effective when the work has a shape close to a circle.

With this configuration, the air cylinder 20
As a result, the plate 13 moves up and down, and the air cylinder 17 fixed to the plate 13 removes the gasket 1 whose knockout pin 19 is chucked by the chuck mechanism. Less than,
The operation of this rotation separating mechanism will be described. Now, the plate 13 is in the lowered position, and the gasket 1 supplied from the magazine 2 is positioned and gripped by the chuck portion 11. Next, when the actuator 14 is rotated,
The gasket 1 chucked through the chuck mechanism 11 including the support plate 5, the guide 3 and the claw 6 rotates. At this time, the remaining gaskets 1 including the next gasket 1
The rotation is restricted by the guide hole formed in the separation block 4 or the magazine 2, and peeling occurs at the contact surfaces of both gaskets 1.

In this embodiment, since the step 31 of the guide 3 engages with the inner peripheral surface of the gasket 1 to be separated over the entire circumference of the gasket 1, the gasket 1 is less deformed,
The entire gasket 1 can be uniformly urged to rotate,
As a result, a reliable and stable separation condition can be created even in the case where the gasket 1 and the next gasket 1 to be separated are easily stuck due to the influence of burrs or moisture.

(Knockout Mechanism) Next, the knockout mechanism will be described. An air cylinder 17 is vertically fixed to the front end surface of the plate 13, and a support plate 18 is fixed to the tip of the piston rod. A knockout pin 19 is vertically provided from the support plate 18,
The knockout pins 19 are attached so as to match the knockout positions N at three locations of the gasket 1 shown in FIG. Therefore, by driving the air cylinder 17, the support plate 18 and the knockout pin 19 move up and down in conjunction with the actuator 14 and the chuck mechanism 11.

Explaining the knock-out operation, when a rotational deviation of α ° occurs between the gasket 1 and the next gasket 1 to be separated by the rotational separating mechanism as shown in FIG. At the knockout position N of, the end portion of the next gasket 1 appears immediately below the knockout pin 19. Next, when the air cylinder 17 is driven, the knockout pin 1 fixed to the support plate 18
9 descends, and as shown in FIG. 3, the next gasket 1 and the remaining gaskets 1 are pressed downward to prohibit their rotation or elevation.

Therefore, next, when the air cylinder 20 is driven, the gasket 1 to be peeled off which is chucked by the claw 6 rises and the gasket 1 can be reliably separated. Even if the air cylinder 20 is driven, since the knockout pin 19 is urged downward by the air cylinder 17, the pressing force of the next gasket 1 does not decrease. When the air cylinder 20 reaches the rising end position, the air cylinder 17 is driven to drive the knockout pin 19
Raise and return to the original position. (Embodiment 2) A gasket separating apparatus of another embodiment will be described with reference to FIG. However, components having the same basic functions as those of the first embodiment are designated by the same reference numerals.

In this embodiment, the guide 3 does not have the claw 6, and the lower end portion of the outer peripheral surface of the guide 3 is fitted into the inner peripheral surface of the gasket 1 to be peeled off. Reference numeral 31 is a ring-shaped cam fitted and fixed to the outer peripheral surface of the guide 3. A slide base 23 is fixed to the upper surface of the separation block 4,
The slide base 23 holds the partition plate 22 slidably in the horizontal direction. The slide base 23 is formed with a guide hole 230 for guiding the stopper bolt 29 erected on the partition plate 22, and the partition plate 22 is biased toward the cam 31 by the spring 26 housed inside the slide base 23. There is. A rod 28 that comes into contact with the outer peripheral surface of the cam 31 is fixed to the tip end portion 220 of the partition plate 22.
The distance from the axis M is changed with the rotation of. Therefore, when the cam 31 rotates and the upper surface of the next gasket 1 is exposed, the partition plate 22 advances toward the axis M, and as a result, the tip of the partition plate 22 rides on the next gasket 100.

The operation will be further described. After that, when the magazine 2 on which the gaskets 1 are stacked is lowered by a lift operation, the gasket 1 to be peeled, which is gripped by the chuck portion 11, cannot be lowered. It is possible to widen a slight gap between the first stacked layers, and thus the gasket 1 can be reliably separated. Of course, also in this embodiment, the chuck 6 can be provided with the claws 6 and the like as in the first embodiment.

The cam 31 has a shape set so as to obtain an appropriate amount of movement corresponding to conditions such as the setting of the rotational axis position of the work and the guide 3, and the cam 31 follows the cam 31 by the rotation of the guide 3. The linear stroke of the partition plate 22 can be obtained. (Modification) FIG. 9 shows a case in which the rotation axis M and the work axis C are displaced when the work 41 is a round and solid thin plate part, and 42 is the gasket 1. The magazine 43 is housed in a stacked state inside, and 43 is a rotatable separating mechanism, which has a plurality of claws 430 that engage with the outer peripheral surface of the work 41. 44 is a knockout pin. The work 41 can be separated by rotating the claws 430 and pushing out by the knockout pin 44.

FIG. 10 shows a hollow thin plate component having a round shape in the work 51. The inner peripheral surface of the work 51 is slidably held by a magazine 52. Has an inner guide portion 530 which engages with the outer peripheral surface of the work 51, and the outer guide portion 531 which engages with the outer peripheral surface of the work 51. The work 51 to be separated is held by the separation portion 53, and the rotation of the separation portion 53 and the knockout pin are performed. The work piece 51 is separated by the ejecting operation by 54.

FIG. 11 is a thin plate component having a quadrangular shape of the work 61 and having a solid and pin hole. The pin hole 610 is slidably held by a shaft-shaped magazine 62, and the separating portion 6 is provided.
3 has a pin 630 which can be fitted in a pin hole of the work 61, and a magnet 631 which is arranged at the center. The work 61 is attracted and held by the magnet 631 of the separating portion 63, and is separated by the rotation of the separating portion 63 and the push-out operation by the knock pin 64. (Effects of Embodiments) According to these embodiments, the magazine is
At least one of the outer circumference and the inner circumference of the thin plate component is slidably arranged in the thickness direction, and thus it can be applied to thin plate components of various shapes such as solid, hollow, and with pin holes.

When the chucking method is limited to the gripping method, since a plurality of sheets can be held, the required number of thin plate components can be separated, and when the number of works to be separated is one,
Various holding methods can be selected. Since the rotation separating mechanism is formed separately from the magazine, the component supplying means can be simple and inexpensive as compared with the conventional one having the separating mechanism in the magazine.

Further, by setting the work axis C as an offset with respect to the axis M of the rotation separating mechanism, it becomes possible to separate even thin plate parts having a round outer periphery, for example. Further, by pressing the knockout pin against the surface of the next work exposed by the rotation, the rotation of the remaining work can be effectively prohibited. Furthermore, by inserting a plate-shaped partition on the surface of the next work exposed by rotation, the thin plate parts are deformed and
Reliable separation is possible even when they are in close contact,
In particular, peeling becomes easy even when a suction holding method such as a magnet type or a vacuum pressure type which is a simple and compact holding method is adopted.
