Description

Blank material separation device and blank material separation system using the same

The present invention relates to a separation device used for a destacker, and more particularly to a separation device that reliably lifts only one uppermost blank from a stack.

In an ordinary destacker, a large number of plate-shaped blank materials to be processed are stacked to form a stack.
Therefore, in the first stage of the processing process, it is necessary to pick up blank materials one by one from the stack and send them to the next processing area. For this purpose, a process of continuously separating the blank materials is indispensable.

The blank materials stacked on the stack may be in close contact with each other due to a vacuum between the blank materials or an oil film formed on the surface, and may be difficult to separate.
In order to solve this, various separation apparatuses have been developed.

For example, there is known a device that magnetizes all the blanks of a stack to the same polarity by a magnet and lifts the uppermost blank by its magnetic force (repulsive force).
However, this is applicable only to a blank material that can be magnetized, and has a drawback that it cannot be applied to other materials such as aluminum, copper, wood, acrylic, etc. that are widely used for industrial purposes.

In addition, there is an air knife that peels off the top blank material and the blank material directly below by blowing high-pressure air toward the stack, and lifts the top blank material.
This has the advantage that it can be applied universally regardless of the type of blank material, but the directivity of the blown air cannot be completely controlled, resulting in poor energy efficiency, high running costs, and high noise. There is a drawback.

For this reason, a separation device is known in which a sawtooth push-up bar is moved to mechanically separate the uppermost blank from the stack (see, for example, Patent Documents 1 and 2).
This is provided with a blade having serrated teeth, and when the blade abuts against the stack diagonally upward from below, the blank material of the stack is caught on the blade teeth and lifted up.
Since the blank material is lifted by mechanical contact, it can be used regardless of whether the blank material constituting the stack is a magnetic material, a non-magnetic material, or a mixture thereof, and is highly versatile.
Further, since the blade teeth act only on the contact portion, the efficiency is high in terms of energy.

However, in such a conventional separating apparatus, the operation of the blade is uniquely determined, and the blade teeth may act on a blank material other than the uppermost blank material.
As a result, not only the top blank material but also several blank materials may be unexpectedly lifted simultaneously.
In particular, such a tendency was conspicuous when the blank was thick or heavy.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings as necessary.
In the drawings, the same elements are denoted by the same reference numerals, and redundant description is omitted.
Further, the positional relationship such as up, down, left and right is based on the positional relationship shown in the drawings unless otherwise specified.
Further, the dimensional ratios in the drawings are not limited to the illustrated ratios.

FIG. 1 is a perspective view of the separation device A. FIG.
FIG. 2 is an explanatory view showing a side surface of the separation device A. FIG.
The separation device A of the present invention is a separation device A for separating the uppermost blank material B1 from the blank material B1 directly below the stack B in which a plurality of blank materials B1 are stacked.

The separating device A includes a push-up bar 5 for separating the blank B1, a first slider body 1 attached to a base 51 of the push-up bar 5, a second slider body 9 in front of the first slider body 1, and a first A linear motion mechanism 2 that indirectly moves the slider body 1, a balance bar 3 that connects the linear motion mechanism 2 and the first slider body 1, a long hole 31 provided in the balance bar 3, and a central portion of the balance bar 3 And a guide plate 4 attached to the side wall portion 6, and a guide hole 41 and a guide surface 42 formed in the guide plate 4.
A front wall portion 7 is provided at the front end of the side wall portions 6 so as to extend over the two side wall portions 6.
As will be described later, the side wall 6 is provided with an air nozzle (not shown), and the front wall 7 is provided with a magnet 8.

Furthermore, one end of the balance bar 3 is pivotally attached to one end of the linear motion mechanism 2, the other end of the linear motion mechanism 2 is pivotally attached to the side wall portion 6, and the balance bar 3 is centered at the central portion thereof. Is pivotally attached to the side wall portion 6 and can be rotated.
That is, the side wall portion 6 is in a state of pivotally supporting the central portion of the balance bar 3.
The first slider body 1 is loosely inserted into the elongated hole 31 and the guide hole 41 of the balance bar 3, and the second slider body 9 is in contact with the guide surface 42.
The first slider body 1 is guided along the guide hole 41, and the second slider body 9 is guided along the guide surface 42, so that the push-up bar 5 can move in the front-rear and vertical directions.
Thereby, even when the push-up bar 5 moves, the uppermost blank material B1 can be reliably rolled up by stably contacting the blank material B1 without moving.
The trajectory of the push-up bar 5 becomes constant, and the contact with the blank material B1 is stable.
Moreover, energy efficiency becomes high.

One end of the linear motion mechanism 2 is pivotally attached to one end of the balance bar 3, and when the linear motion mechanism 2 reciprocates in the front-rear direction, the balance bar 3 rotates according to the movement.

The first slider body 1 of the push-up bar 5 is loosely inserted into the elongated hole 31 on the side opposite to the side attached to the linear motion mechanism 2 of the balance bar 3, and the first slider body 1 is attached to the guide plate 4. It is loosely inserted in the guide hole.
The turning movement of the balance bar 3 is converted into the reciprocating movement of the first slider body 1 without difficulty, and the movement of the balance bar 3 driven by the linear motion mechanism 2 is transmitted to a push-up bar 5 described later.

Here, the push-up bar 5 includes a base portion 51 having two slider bodies and a tooth portion 52 having serrated teeth.
The tooth part 52 is detachably provided on the base part 51, and the tooth part 52 is provided in an obliquely upward direction.
Since the push-up bar 5 is detachably attached to the base portion 51, it can be replaced when the teeth of the tooth portion 52 are worn.

3 to 6 are side explanatory views showing the relationship between the tooth portion 52 and the blank material B1.

FIG. 3 is an explanatory side view showing a state before the end of the blank material B1 is rolled up in a state where the step B1 is not formed.

FIG. 4 is an explanatory side view showing a state after the end portion of the blank material B1 is rolled up in a state where the step-like slope is not formed.
Thus, the state in which the blank B1 does not form a step-like inclination is a case where the extrusion device C located at the opposite positions is not used.

When the push-up bar 5 is moved, the sawtooth-like tooth portion 52 lifts up the end portion of the blank material B1.
Usually, the tooth pitch of the tooth portion 52 is set to be smaller than the thickness of the blank material B1 as a target.
In this case, the tooth tip of the tooth portion 52 acts to slightly bite into the end surface of the blank material B1 or to push up the end surface by friction between the tooth tip and the end surface of the blank material B1.
As a result, the end portion of the blank material B1 is rolled up.
Further, since the serrated teeth are formed in a certain region, even if the position where the push-up bar 5 abuts on the uppermost blank material B1 is shifted upward from the target position, the blank material B1 is surely secured. Can be raised.

FIG. 5 is an explanatory side view showing a state before the end portion of the blank material B1 is rolled up in a state where the blank material B1 forms a step-like slope.

FIG. 6 is an explanatory side view showing a state after the end portion of the blank material B1 has been rolled up in a state where a stair-like inclination is formed.
Also in this case, the tooth tip of the tooth portion 52 acts to slightly bite into the end surface of the blank material B1 or to push up the end surface by friction between the tooth tip and the end surface of the blank material B1.
Or the tip of a tooth may act so that it may put up and push up the end part of the blank material B1 of the top sheet.
As a result, the end portion of the blank material B1 is rolled up.

Compared with the case of said FIG.3 and FIG.4, the end surface of the stack | stuck B forms the step-like inclination by being pressed by the extrusion apparatus C. FIG.
Thereby, since the uppermost blank material B1 protrudes most, the tooth | gear part 52 does not touch blank materials B1 other than the uppermost blank material, and only the uppermost blank material B1 can be rolled up reliably. it can.
By the way, the stack B is lifted by the lifter L for the entire stack every time one blank material B1 is picked up, and when the number of the stack B is lifted by the lifter L every time a plurality of sheets are picked up continuously. There is.
In the latter case, the blank material B1 at the top of the stack is sequentially lowered, but the problem is not caused because the serrated teeth of the tooth portion 52 are formed in a certain region.

The separation device A is provided with side wall portions 6 so as to sandwich the above-described members on both the left and right sides, and protects the internal components.

FIG. 7 is a perspective view showing the guide plate 4.
The guide plate 4 is detachable from the side wall 6 and includes a guide hole 41 and a guide surface 42 formed adjacent to the front side of the guide hole 41.
The upper surface of the thick part formed in the guide plate 4 is a guide surface 42, and this guide surface 42 has a horizontal plane and an inclined plane continuous to the horizontal plane.
The side wall 6 is provided with a screw hole for attaching the guide plate 4, and the guide plate 4 can be attached to the side wall 6 by screwing a bolt on the guide plate side into the screw hole.
Therefore, the guide plate 4 can be removed from the side wall portion 6 by removing the bolts, and can be easily replaced with the guide plate 4 having different guide holes 41 and guide surfaces 42.
By changing the movement (that is, the track) of the push-up bar 5, it is possible to cope with the blank material B1 having a different thickness, shape, and material.

The first slider body 1 moves along the guide hole 41 and the second slider body 9 moves along the guide surface 42, whereby the push-up bar 5 performs a specific movement.
For example, the push-up bar 5 can move obliquely upward and then move horizontally.
Moreover, it can retract to the original position.
In this case, as shown in FIG. 7, the guide hole 41 is provided with a horizontal hole and an inclined hole continuing to the horizontal hole so as to correspond to the horizontal surface and the inclined surface of the guide surface 42. The guide hole 41 and the guide surface 42 are provided in parallel. By providing these in parallel, the push-up bar 5 is guided by the two guide holes 41 and the guide surface 42, the track of the push-up bar 5 becomes constant, and the contact with the blank material B1 is more stable.
Since the movement of the push-up bar 5 is determined by the shapes of the guide hole 41 and the guide surface 42, the movement of the push-up bar 5 can be changed to a different one by exchanging the guide plate 4 having these.

Here, regarding an example of the movement of the push-up bar 5, the push-up bar 5 advances obliquely upward and contacts the blank material B1.
At this time, the tooth portion 52 of the push-up bar 5 acts to lift up the end portion of the blank material B1.
Thereafter, the push-up bar 5 tries to advance straight, but the movement is blocked by the blank material B1.
As a result, starting from the first slider body 1, the front moves upward so as to lift the neck.
That is, the push-up bar 5 is further rotated upward about the moving first slider.
Thereby, the blank material B1 at the top of the stack in contact with the tooth portion 52 of the push-up bar 5 is surely rolled up.

Incidentally, an air nozzle (not shown) is provided on the side wall 6 so as to open forward.
The air nozzle is provided on the side wall portion on the other side in FIG.
When the separation device A of the present invention lifts the uppermost blank material B1 from the stack B, the air nozzle blows high-pressure air between the uppermost blank material B1 and the blank material B1 directly below the uppermost blank material B1.
Thereby, even when the blank materials are in close contact with each other by a vacuum, an oil film, etc., the separation action can be assisted by blowing air, and the push-up bar 5 can more reliably lift the blank material B1 at the top of the stack. .

A front wall portion 7 is provided at the front end of the side wall portions 6 so as to extend over the two side wall portions 6.
In the center of the front wall portion 7, a penetrating portion 10 is provided for the push-up bar 5 to pass through the front wall portion 7.
The push-up bar 5 normally stands behind from the front wall portion 7 and, when necessary, passes through the through portion 10 and faces forward.

Furthermore, the front wall portion 7 is provided with a magnet 8 (permanent magnet or electromagnet), which is used when separating the blank material B1 having magnetism.
By using the magnet 8, the blank material B1 at the top of the stack can be separated in a non-contact manner without using the push-up bar 5.
When the blank B1 having no magnetism is peeled off, the magnet 8 cannot exert its function, and therefore the separating function is exhibited by the push-up bar 5.
Further, for the stack B in which the blank material B1 having magnetism or the blank material B1 not having magnetism is mixed, the functions of the push-up bar 5 and the magnet 8 are operated together to separate the blank material B1 at the top of the stack. be able to.

FIG. 8 is a schematic side view for explaining the arrangement of the separation device A, the stack B, and the extrusion device C.

The stack B is formed by stacking the blank material B1 on the seating surface of the lifter L that can move up and down.
As described above, the lifter L has a case where the entire stack is lifted every time one blank material B1 is picked up, and a case where a lifter L is lifted by the number of sheets each time a plurality of lifters L are picked up.
In the former case, every time the uppermost blank material B1 is rolled up, the thickness of the blank material B1 raised is increased, so that the uppermost blank material B1 is always at the same height.
Therefore, the push-up bar 5 of the separation apparatus A can lift the blank material B1 at the top of the stack at a constant position in the vertical direction, and the separation performance becomes uniform.

By the way, the outer edge of the stack B is supported by a plurality of positioning pins.
Thereby, blank materials do not shift in the horizontal direction, and the stack B is always in a stable state.
In addition, by appropriately adjusting the position of the positioning pin, it is possible to deal with a stack B made of blank material B1 having a different size or an amorphous blank material B1.

The separation apparatus A of the present invention may be used alone, but is usually used together with the extrusion apparatus C.
When used together with the extrusion device C, the end of the blank B1 is inclined stepwise, so that the action as shown in FIGS. 5 and 6 is exhibited.
A device having the separation device A and the extrusion device C is a separation system.

In the separation system, the separation device A and the extrusion device C are arranged to face each other with the stack B interposed therebetween.
In this case, the separating device A is arranged so that the push-up bar 5 faces the stack B. Similarly, the pushing device C on the opposite side through the stack B has the pressing portion C1 facing the stack B. Placed in.

The extrusion device C includes a pressing portion C1 that reciprocates in the horizontal direction and presses the end portions of a plurality of blank materials B1 above the stack B.
The pressing portion C1 has an inclination in which the upper side protrudes toward the stack side and the lower side recedes from the stack side.
The pressing part C1 presses the blank material B1 at the top of the stack and the plurality of blank materials B1 below it all at once, so that their end parts are shifted to form a step-like slope, toward the separating device A. Protruding.

In this case, the uppermost blank material B1 is pushed out so as to protrude most toward the separating device A side.

In the extrusion device C, when the uppermost blank material B1 of the stack is lifted, an unillustrated extrusion device side air nozzle for blowing air between the uppermost blank material B1 and the blank material B1 immediately below the uppermost blank material B1. Is attached.
As with the air nozzle of the separator A, this removes the adhesion between the blank material B1 at the top of the stack and the blank material B1 directly below it due to vacuum, oil film, etc., and the separator A lifts only the top blank material B1. Assist the operation.

Further, the extrusion device C is provided with a magnet (not shown), and the magnetic blank material B1 can be separated without contact.
The push-up bar 5 of the separation device A and the pressing portion C1 of the extrusion device C are controlled to move in synchronization.

Here, the movement of the push-up bar 5 of the separation device A and the pressing portion C1 of the extrusion device C will be described.
FIG. 9 is a side view illustrating a state in which the pressing portion C1 of the extrusion device C presses the blank material B1 at the top of the stack and the plurality of blank materials B1 below it at a time and protrudes so as to be inclined stepwise. FIG.
It is a previous stage until the push-up bar 5 of the separating device A comes into contact with the blank material B1, and the pressing part C1 of the extrusion device C advances to separate the uppermost blank material B1 and the blank material B1 directly below the separating device. This is a state in which a step-like slope is formed by extruding to the A side.
In this case, the push-up bar 5 moves backward and is in a standby state.

FIG. 10 is a side view illustrating a state in which the push-up bar 5 of the separating apparatus A is in contact with the blank material B1.
This is a stage after the pressing by the pressing portion C1 of the extrusion device C is completed, and this time the push-up bar 5 of the separation device A advances obliquely upward and contacts the uppermost blank material B1.
The pressing part C1 of the extrusion device C stops and is at the same position.
Note that the uppermost blank B1 is located within a range where the sawtooth teeth of the tooth portion 52 are formed.

FIG. 11 is a side view illustrating a state in which the push-up bar 5 of the separating apparatus A has lifted up the blank material B1 at the top of the stack.
The push-up bar 5 moves forward and acts to lift up the uppermost blank material B1.
Since the push-up bar 5 acts only on the uppermost blank B1, the extra weight is not added and the energy efficiency is high.
The pressing part C1 of the extrusion device C stops and is at the same position.

Thereafter, the uppermost blank B1 separated by the push-up bar 5 is conveyed to another place (next step) by a conveying means such as a suction cup (not shown).

Thus, the blank material B1 at the top of the stack can be efficiently separated while the separation device A and the extrusion device C cooperate.

12 to 14 are top views schematically showing the positional relationship between the separation device A and the extrusion device C. FIG.
In the separation system shown in FIG. 12, one separation device A and one extrusion device C facing each other across the stack B are used as a pair.

Further, in the separation system shown in FIG. 13, one separation device A and one extrusion device C facing each other are paired, and one reverse separation device A and one extrusion device C facing each other are paired. Two pairs in total are arranged.
Thereby, it is possible to switch the side (left and right in the figure) on which the separating apparatus A lifts the blank material B1.

Further, the separation system shown in FIG. 14 is configured such that one pair of extrusion devices C facing the separation device A is arranged in two pairs in the front and rear and two pairs in the left and right.
The blank material B1 can be rolled up from any of the front and rear and left and right directions.
As a result, it is possible to sufficiently cope with lot change and change in the conveyance direction.

The preferred embodiment of the present invention has been described above, but the present invention is not limited to the above embodiment.

For example, it is also possible to provide a left-right symmetrical structure in which the guide plates 4 are provided on the side wall portions 6 on both sides, the balance bar 3 is paired, and the push-up bar 5 is sandwiched from both sides.
As a result, the movement of the push-up bar 5 becomes more stable.

According to the present invention, only the uppermost blank B1 can be separated and lifted reliably and efficiently.
The present invention is applicable when the workpiece to be processed is a plate material and is in a stacked state, and is widely useful in a separation process of plate material processing including press working.
