Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an apparatus for positioning a plate material (hereinafter referred to as a sheet plate) such as metal or plastic in the X-Y direction.

[Conventional technology]

Conventionally, in order to process or inspect a sheet plate, the sheet plate is sometimes positioned in the X-Y direction. Positioning is performed by pressing the side edges of the sheet plate against the reference plane.

[Problem that the invention attempts to solve]

However, such conventional devices have a problem in that when positioning sheet plates of different dimensions, the center position of the positioned sheet plates changes.

The present invention was devised in view of such problems, and an object of the present invention is to provide an X-Y positioning device that can easily position sheet plates of various sizes in the X-Y direction with the center at a fixed position. With the goal.

[Means for solving problems]

The present invention, which was made to achieve the above object, consists of a base plate on which a seat plate to be positioned is placed, a rotating shaft arranged below the base plate at right angles to the base plate, and a rotating shaft arranged in a relationship surrounding this rotating shaft. four sliding members movable at right angles to each other;
Each slide member includes at least two sheet plate pushing members that are held movably in a direction parallel to the moving direction of the slide member and that are capable of engaging with side edges of the sheet plate placed on the base plate; X having a spring that urges the plate pushing member to a forward position with respect to the slide member, a drive device that reciprocates the rotation shaft, and a link mechanism that converts the reciprocation rotation of the rotation shaft into reciprocation motion of the slide member. -Y
The main topic is positioning devices.

[Effect]

According to the X-Y positioning device configured as described above, when the sheet plate to be positioned is placed on the base plate and the rotating shaft is rotated in one direction, the four slide members are moved in the direction in which they approach the rotating shaft by the link mechanism. A total of eight sheet plate pushing members held by the slide member also move in a direction in which opposing pairs approach each other, and each side of the sheet plate is moved in synchronization with at least two sheet plate pushing members. Push it with a member to position it in the specified position. Thus, even if the size and shape of the sheet plate changes, the sheet plate is centered at the intermediate position between the sheet plate pushing members facing each other, and the X-Y
position in the direction. In addition, the sheet plate pushing member is normally biased to the forward position by a spring with respect to the sliding member, but since it is retractable, when it engages with the side edge of the sheet plate and performs positioning, it presses against the sheet plate. Excessive pressing force is not applied, and deformation and damage to the sheet plate are prevented. When the rotating shaft is rotated in the opposite direction, the four slide members expand,
It can be prepared for the next sheet material.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a plan view of an X-Y positioning device according to an embodiment of the present invention, and FIG. 2 is a sectional view thereof.
In the figure, 1 is a frame, 2 is a support plate, and 3 is a base plate on which a sheet plate 4 to be positioned is placed.
This base plate 3 is formed with eight cutouts 3A through which sheet plate pushing members to be described later pass. Reference numeral 6 denotes a rotating shaft disposed below the base plate 3 at right angles to the base plate 3; 7 a bearing body that rotatably holds the upper end of the rotating shaft 6; 8 connected to the lower end of the rotating shaft 6; This is a drive device such as a rotary actuator that rotates the motor back and forth. Reference numeral 9A denotes a pair of slide members arranged to sandwich the rotation shaft 6 in the X direction, and reference numeral 9B denotes a pair of slide members arranged to sandwich the rotation shaft 6 in the Y direction perpendicular to the X direction. Each slide member 9A, 9B has guide rods 10A, 1 arranged in the X direction and the Y direction, respectively.
It is slidably held at 0B. Figures 3 and 4
As shown in the enlarged view, two bearing blocks 11 are attached to the slide member 9A, and each bearing block 11 slidably holds a pair of slide shafts 12 and 13 extending parallel to the guide rod 10A. . Attached to the tips of the slide shafts 12 and 13 are sheet plate pushing members 14A that can engage with and push the side edges of the sheet plate placed on the base plate 3. Furthermore, a stopper 15 is attached to the rear end of one of the slide shafts 12, and a compression coil spring 16 is provided between the bearing block 11 and the sheet plate pushing member 14A. This coil spring 16 normally biases the sheet plate pushing member 14A in the right direction in FIG. When a force is applied to the pushing member 14A in the left direction in FIG. 3, the sheet plate pushing member 14A is allowed to retreat relative to the slide member 9A. Therefore, when positioning the sheet plate, which will be described later, it is possible to prevent excessive pressing force from acting on the side edges of the sheet plate. In FIG. 1, the bearing block 1 is also attached to the other slide member 9B.
1 is attached, and a sheet plate pushing member 14B is held movably in the Y direction via this bearing block 11. In this way, eight sheet plate pushing members 14A, 14B are arranged at the peripheral portion of the base plate 3.

In Fig. 1 and Fig. 2, 20 is a disk attached to the rotary shaft 6, 21 is a link connecting the disk 20 to each slide member 9A or 9B, and the disk 20 and the link 21 constitute a link mechanism that converts the reciprocating rotation of the rotary shaft 6 into the reciprocating motion of each slide member. This link mechanism is shown in Fig. 2 and Fig. 3.
5. The link 21 is attached to the disk 20 at a position away from the center of the rotating shaft 6 by a pin 22.
The link 21 is rotatably connected to the link 21 by a groove 23 extending in the longitudinal direction. A bearing block 24 is attached to the underside of the link 21, and an adjustment screw 25 equipped with a handle 26 is held in the bearing block 24 in a manner that allows it to rotate but does not move in the axial direction, and in parallel with the groove 23 of the link 21. A connecting member 28 is engaged with the adjustment screw 25, and is adapted to move in the longitudinal direction by the rotation of the adjustment screw 25. The connecting member 28 has a portion 28 that is slidable within the groove 23 described above.
The adjusting screw 25 has a connecting member 28a and a pin portion 28b at its upper portion, which is rotatably connected to the connecting portion 9a of the slide member 9A. Therefore, by rotating the handle 26 at one end of the adjusting screw 25, the connecting member 28 moves in the longitudinal direction of the link 21, and the slide member 9A moves accordingly. This makes it possible to adjust the position of the sheet plate pressing member 14A. Reference numeral 29 denotes a lock handle for fixing the adjusting screw.

Next, a positioning operation in the apparatus having the above configuration will be explained. Place the seat plate 4 to be positioned on the base plate 3, and move the rotating shaft 6 to arrow A in FIGS. 1 and 5.
Rotate in the direction. Due to this rotation, the disk 20,
The slide members 9A and 9B simultaneously move in a direction toward each other via a link mechanism including the link 21 and the like. Therefore, in FIG.
The left and right side edges of are positioned at intermediate positions between both sheet plate pushing members 14A by mutually opposing sheet plate pushing members 14A, and at the same time, the upper and lower side edges are positioned between both sheet plate pushing members 14B by mutually opposing sheet plate pushing members 14A. It is positioned at an intermediate position of the sheet plate pushing member 14B. Thus, positioning in the X and Y directions is performed simultaneously. At this time, since the sheet plate is positioned at the center in both the X direction and the Y direction, the center of the sheet plate is always positioned at a predetermined position regardless of the dimensions of the sheet plate. Also, during positioning operation, the sheet plate pushing members 14A, 14B can retreat with respect to the slide members 9A, 9B, so that excessive pressure is not applied to the sheet plate, which may cause the sheet plate to bend or be damaged. Never. After the positioning operation is completed, the rotating shaft 6 is rotated in the opposite direction and the apparatus waits for the next sheet plate.

[Effect of idea]

As is clear from the above explanation, the X-
The Y positioning device is provided with a slide member equipped with at least two sheet plate pushing members so as to face each other in the X direction and the Y direction, and these slide members are brought close to each other simultaneously by rotation of a rotating shaft in one direction. Since it is configured to move, by simply rotating a single rotating shaft, each side of the sheet plate can be simultaneously pushed toward the center by at least two sheet plate pushing members to position the sheet. To quickly position a sheet plate so that its center is at a predetermined position regardless of the shape and dimensions of the plate. Moreover, although the sheet plate pushing member is normally biased to the forward position by a spring with respect to the slide member, it can be moved backward, so when engaging with the side edge of the sheet plate to perform a positioning operation,
No excessive pressing force is applied to the sheet plate,
Deformation and scratches on the sheet plate can be prevented.
