DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a positioning device that accurately positions a member to be positioned at a predetermined position.

[Conventional technology]

2. Description of the Related Art Conventionally, when manufacturing products such as bags, shoes, clothing, etc., it is necessary to sew various parts to be sewn onto a fabric as the main body of the product.
In this case, the sewing work involves the worker setting the fabric and the piece to be sewn in a stacked state on the sewing machine, and moving the fabric by hand according to a predetermined pattern to integrate the piece to be sewn into the fabric. . However, this requires a great deal of effort on the part of the operator. On the other hand, recently, the fabric is placed on a table that moves in the X and Y directions, and the table is automatically moved according to a predetermined pattern with the piece to be sewn (positioned member) placed and set on the fabric. There have also been proposals that allow sewing to be done while moving.

[Problem that the invention seeks to solve]

However, with such a device, the worker must stack and set the pieces to be sewn as the positioning members at predetermined positions on the fabric, and this has the disadvantage that the quality may vary due to deviations in the set positions. It was hot.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a positioning device that can automatically and accurately position a member to be positioned.

[Means for solving problems]

In the present invention, a member to be positioned is suctioned by a suction part having a hole communicating with an intake source and an exhaust source, and after being positioned by a positioning part, the member is removed by an exhaust source.

[Effect]

The member to be positioned is attracted to the suction part by suction air,
Furthermore, the positioned member is removed from the suction section by exhaustion. In this case, the suction section is accurately positioned by the positioning section at the position where the member to be positioned is to be placed and set.

EMBODIMENT OF THE INVENTION Below, the Example of the positioning device based on this invention is described based on drawing. In this embodiment, a case is shown where the positioning device is applied to a label supply device, and this label supply device supplies, for example, a label to be sewn to a predetermined portion of a fabric as a workpiece. be.

In the figure, 1 is a label supply device, and the label supply device 1 supplies a label R to a predetermined position on a fabric A set on a table of a processing device such as a sewing machine. R is sewn onto fabric A. This label supply device has the following configuration. That is, the above fabric A
is set on the table above while being held between the cassettes K shown in FIG.
As shown in FIG. 3, a label mounting hole 2 is formed in the holder. As shown in FIG. 1, the label supply device 1 includes a holding cylinder 3 with an open top that holds a plurality of labels R in a stacked state, and a holding cylinder 3 that holds a plurality of labels R in a stacked state, and a single label R, R, etc. inside the holding cylinder 3. It is comprised of a working section 4 that takes out the cassettes K one by one and supplies them to the mounting hole 2 of the cassette K. Here, the working section 4 includes a column 5 and an arm 6 disposed horizontally at the upper end of the column 5.
, a movable part 7 that extends and contracts with respect to the arm 6, and an air cylinder 9 shown in FIG. , and a label holder 11 attached to the lower end of the rod 10 of the air cylinder 9. When the movable section 7 is at its shortest position, the air cylinder 9 is located directly above the holding cylinder 3, and when the movable section 7 is at its maximum extension, the air cylinder 9 is positioned directly above the label mounting hole 2 of the cassette K. It seems to reach directly above.

The label holding section 11 is composed of a plate section 12 attached to the lower end of the rod 10, and a suction section 14 provided on the plate section 12 via intake and exhaust pipes 13, 13. has two holes 1
5, 15 are formed, and the holes 15, 15 communicate with one side of the intake/exhaust pipes 13, 13, and the other side of the intake/exhaust pipes 13, 13 communicate with an intake/exhaust section described later. Therefore, when the suction/exhaust section is operated and air is inhaled, the label R is adsorbed to the suction section 14, while when the suction/exhaust section is exhausted, the suction section 1
Label R will be removed from 4.

Here, when the movable part 7 is in the most extended position,
When the rod 10 of the air cylinder 9 is extended,
The suction portion 14 is adapted to fit into the label mounting hole 2 of the cassette K.

Reference numerals 16 and 16 denote guide tubes that are attached to the support piece 8 in a vertically penetrating state, and a guide rod 17 is inserted into each guide tube 16 so as to be slidable in the vertical direction. The lower end of the rod 17 is attached to the plate portion 12, so that the guide rods 17, 17 are attached to the rod 10 of the air cylinder 9.
guides the vertical movement of the Further, reference numerals 18, 18 are locking rods constituting a locking body provided downward in the longitudinal direction of the plate portion 12, and the lower portions of the locking rods 18, 18 are connected to the suction plate as shown in FIG. 14, and its lower end is tapered downward. Here, both the locking rods 1
The width of separation between cassettes 8 and 18 is as shown in the same figure.
The distance between the positioning holes 19, 19 constituting the locking portion formed on both sides of the label mounting hole 2 is the same as that of the locking rods 18, 18. It has approximately the same diameter as Therefore,
When the rod 10 of the air cylinder 9 extends downward, the locking rods 18, 18 are inserted into the label mounting hole 2 of the cassette K before the suction portion 14 of the label holding portion 11 is fitted into the label mounting hole 2 of the cassette K. 2 engages with the positioning holes 19, 19 (constituting a locking part) on both sides, and is accurately positioned.

Thus, the locking rods 18, 18 and the positioning holes 19, 19 constitute a positioning section.

FIG. 4 shows the configuration of the above-mentioned intake and exhaust section.

In the figure, 20 indicates an exhaust source, 21 indicates an intake source, and 22 indicates a 3-port valve as a switching means. As a result, when the 3-port valve 22 is in the position B as shown in the figure, negative pressure is created in the holes 15, 15 on the lower surface of the suction section 14 of the label holding section 11 due to the suction action of the suction source 21, so that the label R is suctioned. On the other hand, when the 3-port valve 22 is set to A, the exhaust source 20 communicates with the holes 15, 15 of the suction section 21, so that the suction section 14 separates from the label R due to exhaust gas.

Here, the expansion and contraction of the movable portion 7, the expansion and contraction of the rod 10 of the air cylinder 9, and the operation of the three-port valve 22 are interlocked with each other. That is, at the time of start-up, the movable portion 7 is in the retracted state, and the three-port valve 22 is in the position B as shown in the figure.
When a start switch (not shown) is turned on, the support column 5 moves downward, and the rod 10 of the air cylinder 9 extends.
After the suction part 14 on the tip side comes into contact with the label R inside the holding cylinder 3, the rod 10 is shortened and the movable part 7 moves upward. Therefore, one label R inside the holding cylinder 3 is adsorbed onto the adsorption section 41 . Moreover, the movable part 7
The rod 10 of the air cylinder 9 begins to extend when the support column 5 is at its highest position, and the rod 10 of the air cylinder 9 begins to extend when the movable part 7 is at its highest position.

Further, the 3-port valve 22 is connected to the air cylinder 9.
When the adsorption portion 14 on the tip side is fitted into the label mounting hole 2, the state changes from B to A. Therefore, at the most extended position of the rod 10 of the air cylinder 9, the label R is separated from the adsorption section 14 by the exhaust from the exhaust source 20.

On the other hand, after the label R is detached from the adsorption section 14, the rod 10 of the air cylinder 9 is shortened, and furthermore, when the rod 10 of the air cylinder 9 is at its shortest length, the movable section 7 begins to shorten. It is starting to return to that state.

Next, its effect will be explained.

First, when you press the start switch, air cylinder 9
The rod 10 is extended, and the label R inside the holding cylinder 3 is
One sheet is sucked into the suction section 14 by suction.

Thereafter, the rod 10 of the air cylinder 9 is shortened, and the movable part 7 is extended at the highest position. Here, at the most extended position of the movable portion 7, the air cylinder 9 reaches above the label mounting hole 2 of the cassette K.

Thereafter, the rod 10 of the air cylinder 9 begins to extend downward, and the suction portion 14 fits into the label mounting hole 2 of the cassette K at the most extended position of the rod 10.

However, at this time, before the suction part 14 is fitted into the label mounting hole 2, the locking rods 18, 18 forming the positioning part are engaged with the positioning holes 19, 19 on both sides of the label mounting hole 2. Therefore, the suction portion 14 fits accurately into the label mounting hole 2.

Then, the suction section 14 is attached to the label mounting hole 2.
When the label R is inserted into the suction part 14, the three-port valve 22 is switched from B to A, so that the label R adsorbed on the suction part 14 is removed from the suction part 14 by exhaust air. Therefore, after the suction portion 14 is raised, the label R remains in the label mounting hole 2.

In addition, although the above embodiment shows the case where the present invention is applied to a sewing device, the present invention is not limited to this.
It can also be applied to other processing equipment.

〔effect〕

As explained above, according to the present invention, a member to be positioned is sucked by the suction part having holes communicating with the suction source and the exhaust source, and after the suction part is positioned by the positioning part, it is removed by the exhaust source. As a result, the member to be positioned can be carried to a predetermined position and positioned accurately.
