Description

The present invention relates to a dispensing device.
More specifically, the present invention relates to a feeding device including a take-out position where a stack made of a plurality of blank materials is placed, and a carry-in device for carrying the blank material into the press line from the take-out position.

In general, the blank material is carried into the press line using a carry-in device such as a destack feeder.
In this method, a blank material is sucked one by one from a stack placed at a predetermined position, and is carried into a press line.

  However, in this method, it is necessary to separately arrange the stack at a predetermined position every time the stack is exhausted. Therefore, it takes time to arrange the stack, and it cannot be said that the productivity is excellent.

On the other hand, the pallet loaded with the sheet stack in a predetermined arrangement is loaded into the destack position, the pallet loading device for unloading the pallet from the destack position after supplying the sheet stack on the pallet, and the destack position, An XY table that moves the loaded pallet in the X-axis and Y-axis directions to position the selected sheet stack on the pallet at the destack point a; and is installed below the destack point a. A destack feeder is disclosed that includes a stack lifter that lifts the sheet stack positioned at the destack point a to a position where the vacuum lifter can be held through a through-hole opened in the pallet (for example, Patent Document 1).
According to this method, productivity is improved as compared with the above method.
Japanese Patent Laid-Open No. 06-154919

  However, since the destack feeder described in Patent Document 1 must move to the next pallet when the sheet stack placed on the pallet is exhausted, it takes time to move to this pallet, and the productivity is sufficiently high. It cannot be said that it will improve.

  In addition, since the destack feeder is large in size, it requires a sufficient space for arranging the device, and there is a disadvantage that the cost of the device itself increases.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a feeding device that is low in cost and can sufficiently improve productivity even in a relatively narrow space.

  The present inventor has intensively studied to solve the above problems, and adopts a method in which two take-out positions on which the stack can be placed are provided, and when the blank material is carried in from one side, the stack is prepared on the other side. As a result, the inventors have found that the above problems can be solved unexpectedly, and have completed the present invention.

  That is, the present invention is (1) carrying the blank material into the press line from the first take-out position and the second take-out position where the stack composed of a plurality of blank materials is placed, and from the first take-out position or the second take-out position. A first feeding position and a second feeding position are positioned so as to be equidistant from the carry-in port into which the blank material of the press line is carried, And it exists in the delivery apparatus positioned so that the 1st extraction position and the 2nd extraction position may become symmetrical with respect to the carrying-in direction of the blank material.

  The present invention includes (2) a loading device having a central axis, an arm connected to the central axis so as to be rotatable, and suction means capable of sucking a blank material at the tip of the arm. In the dispensing device according to the above (1), the first extraction position and the second extraction position are positioned so as to be equidistant from the central axis.

  The present invention includes (3) a first standby position for waiting the stack, a first stage base movable between the first standby position and the first take-out position, and a second standby position for waiting the stack; The second stage stand movable between the second standby position and the second take-out position, and the stack is placed on the first stage stand and / or the second stage stand. Located in the delivery device.

  The present invention includes (4) the above-described (1), comprising: a main arm portion whose arm is connected to the central axis; and a slave arm portion connected to the main arm portion so as to be rotatable. In the delivery device.

  The present invention resides in (5) the feeding device according to (3), wherein a lifting mechanism is attached to the first removal position and the second removal position, and the stack can be moved up and down by the lifting mechanism. .

  This invention exists in the delivery apparatus of the said (1) description whose (6) and a press line are a transfer plus line or a tandem press line.

  This invention exists in the delivery method using the delivery apparatus as described in any one of (7) and said (1)-(6).

  In addition, as long as the objective of this invention is met, the structure which combined said (1)-(7) suitably is also employable.

Since the feeding device of the present invention includes the first take-out position and the second take-out position on which a stack made of a plurality of blank materials is placed, the second time is taken while the carry-in device carries the blank material from the first take-out position. The stack can be prepared at the take-out position, and the stack can be prepared at the first take-out position while the carry-in device carries the blank material from the second take-out position.
The feeding device is positioned such that the first take-out position and the second take-out position are equidistant from the carry-in port into which the blank material of the press line is carried in, and the first take-out position and the second take-out position. Since the position is positioned so as to be symmetrical with respect to the blank material carrying-in direction, the distance from the first take-out position to the press line carry-in and the distance from the second take-out position to the breath line carry-in And become equal.
From this, the movement distance of the blank material when the blank material is carried in by the carry-in device becomes equal.

Therefore, if the carry-in speed of the carry-in device is constant, the time during which the blank material is carried in from the first take-out position can be made equal to the time during which the blank material is carried in from the second take-out position. Thus, it is possible to carry in the blank material, and no adjustment is required when switching from the first removal position to the second removal position.
For these reasons, according to the feeding device of the present invention, it is possible to improve the productivity sufficiently even at a low cost and in a relatively narrow space.

  In the delivery device, the carry-in device has a central axis, an arm connected to the central axis so as to be rotatable, and a suction means capable of sucking a blank material at the tip of the arm. Yes, if the first extraction position and the second extraction position are positioned so as to be equidistant from the central axis, the first extraction position or the second extraction position can be obtained by rotating the arm around the central axis of the loading device. The blank material can be efficiently carried into the press line from the position.

In the delivery device, the first standby position for waiting the stack, the first stage base movable between the first standby position and the first extraction position, the second standby position for waiting the stack, 2 and a second stage stage movable between the second standby position and the second take-out position, and when the stack is placed on the first stage stage and / or the second stage stage, the first or second standby stage The stack is placed on the first or second stage base at the position, and the first or second stage base is moved to the first or second extraction position.

FIG. 1 is a plan view showing an embodiment of a dispensing device according to the present invention.
As shown in FIG. 1, the dispensing device 100 according to the present embodiment includes a first removal position 11a and a second removal position 12a on which a stack made of a plurality of blank materials 15 is placed, and a first removal position 11a or a first removal position. 2 is provided with a carry-in device 20 for carrying the blank material 15 into the press line from the take-out position 12a.

  In the delivery device 100 according to the present embodiment, the blank material 15 placed at the first take-out position 11a or the second take-out position 12a is carried into the press line by the carry-in device 20.

The delivery device 100 includes a first standby position 11b for waiting the stack, a first rail 11c laid between the first standby position 11b and the first take-out position 11a, the first standby position 11b and the first And a first stage base 11 movable between the take-out positions 11a.
The first stage base 11 is slidable on the first rail 11c.
Thereby, the stack placed on the first stage base 11 is transported from the first standby position 11b to the first extraction position 11a.

The delivery device 100 includes a second standby position 12b for waiting the stack, a second rail 12c laid between the second standby position 12b and the second extraction position 12a, the second standby position 12b, And a second stage base 12 movable between the second extraction positions 12a.
The second stage base 12 can slide on the second rail 12c.
Thereby, the stack (not shown) placed on the second stage base 12 is transported from the second standby position 12b to the second extraction position 12a.

A lift mechanism (not shown) is attached to the first take-out position 11a, and the stack disposed at the first take-out position 11a is moved up and down by the lift mechanism.
On the other hand, an elevator mechanism (not shown) is attached to the second extraction position 12a, and the stack disposed at the second extraction position 12a moves up and down by the elevator mechanism.

For this reason, in the said delivery apparatus 100, it is possible to raise a stack to the same height as the entrance 30 with the raising / lowering mechanism, and to carry in the blank material 15 to the entrance 30 with the carrying-in apparatus 20. FIG.
Therefore, the transport device 20 can carry in the blank material 15 only by moving in parallel.

FIG. 2 is a perspective view showing a carry-in device in the delivery device according to the present embodiment.
As shown in FIG. 2, the carry-in device 20 includes a central shaft 21, an arm 22 connected to the central shaft 21 so as to be rotatable, and a suction capable of sucking a blank material at the tip of the arm 22. Means 27.

The arm 22 includes a main arm portion 25 connected to the central shaft 21 and a slave arm portion 26 connected to the main arm portion 25 so as to be rotatable.
The main arm portion 25 is rotatable in the horizontal direction around the central axis 21, and the slave arm portion 26 is rotatable in the horizontal direction around the connecting portion with the main arm portion 25. It has become.
Accordingly, the carry-in device 20 can carry the blank material into the carry-in port of the press line at the shortest distance by folding the main arm portion 25 and the slave arm portion 26.

The suction means 27 is provided with a suction port at the center, and the blank material is sucked by sucking the blank material from the suction port.
The suction means 27 can be expanded and contracted in the vertical direction, and can be sucked in accordance with the position of the blank material.

That is, in the feeding device 100, the amount of the blank material is reduced by repeatedly carrying the blank material, and accordingly, the height of the blank material to be sucked gradually decreases. Since it can expand and contract in the vertical direction, the same position of the blank material can always be sucked.
Thereby, it can suppress that the position shift of the blank material by the carrying-in apparatus 20 arises.

Returning to FIG. 1, in the dispensing device 100 according to the present embodiment, the first removal position 11 a and the second removal position 12 a are positioned so as to be equidistant from the carry-in entrance 30 into which the blank material 15 of the press line is carried. And the first take-out position 11a and the second take-out position 12a are positioned so as to be symmetric with respect to the carrying-in direction A of the blank material 15.
In addition, the carry-in device 20 is positioned such that the first take-out position 11a and the second take-out position 12a are equidistant from the central shaft 21.

  That is, in the delivery device 100, the distance from the first take-out position 11a to the carry-in port 30 of the press line is equal to the distance from the second take-out position 12a to the carry-in port 30 of the breath line. The distance from the extraction position 11a to the central axis 21 is equal to the distance from the second extraction position 12a to the central axis 21.

  Therefore, the central shaft 21 is arranged on a line that is orthogonal to the midpoint of the line that connects the first extraction position 11a and the second extraction position 12a, and the blank material 15 is carried in.

  Therefore, when the feeding device 100 rotates the arm 22 around the central axis 21 of the carry-in device 20, the blank material 15 is transferred from the first take-out position 11a or the second take-out position 12a to the carry-in port 30 of the press line. Can be carried in.

Further, since the distance from the first take-out position 11a to the carry-in entrance 30 is equal to the distance from the second take-out position 12a to the carry-in entrance 30, if the carry-in speed of the carry-in device 20 is constant, the first take-out position 11a The time when the blank material 15 is carried in from the second take-out position 12a is equal to the time when the blank material 15 is carried in from the second extraction position 12a.
Accordingly, it is possible to carry in the blank material 15 at a constant speed and a constant time, and no adjustment is required when switching from the first extraction position 11a to the second extraction position 12a.

  Therefore, according to the delivery device 100 according to the present embodiment, a special device is not required, so the cost is low, and the first extraction position 11a, the second extraction position 12a, and the carry-in device 20 are arranged as described above. This makes it possible to sufficiently improve productivity even in a relatively narrow space.

In the delivery apparatus 100 according to the present embodiment, the press line into which the blank material 15 is carried is preferably a transfer plus line or a tandem press line.
