Description

[Detailed description of the invention] The present invention relates to a plate material supply device, and more specifically, to a plate material supply device that moves a plate material in two dimensions such as forward, backward, upward, and downward movement using a single drive device. .

Conventionally, sheet material feeding devices used for the above-mentioned purpose require vertical movement even if they are limited to reciprocating in one direction, requiring two sets of drive devices, and the need to synchronize the timing, making the device complicated and expensive. I was getting used to it.

The present invention eliminates the above-mentioned drawbacks and provides a device that achieves two-dimensional movement of forward and backward movement and up and down by a single drive means, and is also a device that is capable of not only supplying board materials but also taking them home. be.

Preferred embodiments of the device of the present invention will be described in detail below with reference to the drawings.

For convenience of explanation, in Figures 1 and 2, the direction in which the plate material is transferred to the processing machine is forward, the opposite direction is the rear direction, the direction in which the plate material is sucked and floated is upward, the opposite direction is downward, and the device is placed either upward or forward. Let's call it left and right when looking at it.

First, the base 1 is appropriately installed adjacent to a plate material processing machine, for example, with its longitudinal direction aligned with the plate material supply direction. On one side (upper side in Figure 2) away from the fixed position (lower position of the suction device in Figure 2) where the plate material to be supplied to the plate processing machine is sucked on the base 1, there are installed parallel to the base 1 and mutually. A plurality of parallel guide bars 3 are fixed by front and rear brackets 5, and a base 7 is provided which is guided by the guide bars 3 and is movable in the front and rear directions.

A plurality of slide blocks 9 spaced apart from each other are fixed to the lower surface of the base 7.
A slide block 11 is provided which penetrates through the slide block 9 and engages with the guide bar 3 described above, and spacer plates 13 are provided at the front and rear end surfaces of the slide block 9 to position the forward and backward ends of the base 7. are provided to be replaceable, and a tubular spacer 15 is provided between the front and rear slide blocks 9.

A plurality of guide posts 19 are erected at the upper part of the front end of the base 7 via a sub-plate 17, and a suction device base 21, which is guided by the guide posts 19 and can move up and down, is moved via a slide bush 23. It is provided.

A plurality of bombs 25 whose lower ends are seated on the sub-plate 17 described above are provided to constantly urge the suction device base 21 upward.

A fulcrum stand 27 is erected approximately at the center of the base 7 adjacent to the suction device base 21, and is regulated by two left and right regulating pins 29 at the rear of the base 7, and slides on the base 7 in the front and back direction. A freely movable concave cam block 31 is provided.

A fluid pressure cylinder 35 with a long stroke length is horizontally provided on the upright portion of the rear end protrusion 33 of the base 1, and the front end of a piston rod 37 is fixed to the cam block 31.

Further, it is supported almost at the center by the fulcrum stand 27 described above, and its front end contacts the upper surface of the adsorption device base 21 described above via a roller 39, and its rear end contacts the upper surface of the cam block 31 described above via a roller 41. A seesaw member 43 is provided.

As is clear from FIG. 2, the front end of the suction device base 21 is provided with an arm member 45 projecting at right angles to one side (left side in FIG. 2), and an elongated hole 47 provided at the left end of the arm member 45. A plurality of suction device brackets 49 are fixed to each other with bolts or the like so that the distance between them can be freely adjusted.

The bracket 49 includes, for example, a vacuum cup 51.
Alternatively, a magnetic adsorption device or the like is installed to adsorb and release the plate material through air piping, electrical wiring, etc. (not shown).

Further, in this embodiment, a sensor plate 53 is provided at the front end of the suction device bracket 49, and has the function of detecting that a plate material is being suctioned and sending a signal to a control device or the like.

Next, to explain the operation, FIG. 1 shows a situation in which the cam block 31 is being pulled in the backward direction by the fluid pressure cylinder 35 and is moving.

That is, the suction device base 21 is urged upwardly by the bullet 25 to separate from the base 7, and the roller 41 at the rear end engages with the center recess of the center concave cam block 31 via the seesaw member 43. , the rear end surface spacer plate 13 of the slide block 9 that guides the base plate 7 has not come into contact with the bracket of the guide bar 3.

When the fluid pressure cylinder 35 continues to contract its piston rod 37 from the state shown in FIG. As a result of being forcibly moved backward on the base 7, the roller 41 is pushed up by the front inclined surface of the cam block 31, and the front roller 39 of the seesaw member 43 moves the suction device base 21 against the bomb 25 to a horizontal position. You will be able to descend while maintaining your posture.

That is, when the vacuum cup 51 of this embodiment moves slightly to the right (in the backward direction) from the state shown in FIG. 1, it stops moving and begins to move downward.

When the sensor plate 53 detects that the lower surface of the vacuum cup 51 has come into contact with the upper surface of the plate and issues a signal, the hydraulic cylinder 35 starts to extend its piston rod 37, and the seesaw member 4
3. Since the rear roller 41 is receiving the biasing force of the bullet 25, the cam block 31 first moves forward on the base 7 before the base 7 moves forward, and the roller 41 moves forward on the base 7. The seesaw member 43 rolls on the upper surface and descends.
becomes the state shown in Figure 1.

That is, the vacuum cup 51 is raised and the plate material is floated.

Then, as the piston rod 37 continues to extend,
The roller 41 has to climb the slope of the medium-concave cam block 31, but as mentioned above, since the bullet 25 is resisting, the slide block 9 of the base 7 has less resistance, so the base 7 moves forward. Start.

That is, the vacuum cup 51 moves forward toward the processing machine while keeping the plate material floating.

Then, as the piston rod 37 continues to extend,
The spacer plate 13 at the front of the slide block 9 comes into contact with the bracket 5 of the guide bar 3 at the front, and the forward movement of the base plate 7 is stopped. Further, as the piston rod 37 continues to extend, the cam block 3 moves on the base 7.
1 is forced to move forward, and roller 4
1 moves up the inclined surface of the cam block 31, and the roller 39 at the front of the seesaw member 43 is lowered.

That is, the plate material attracted to the vacuum cup 51 is lowered.

As is clear from the above explanation, the horizontal distance to move the plate material is from the position where the rear surface of the spacer plate 13 attached to the front and rear of the slide block 9 abuts the bracket 5 of the rear guide bar to the position where the front surface touches the front bracket 5. This is the distance until the piston rod makes contact, and the length of the piston rod's subsequent expansion or contraction after the above-mentioned contact is the amount by which the plate material is raised and lowered by the tangent of the front and rear inclination angles of the medium concave cam block. It turns out.

In this way, by exchanging and adjusting the thickness of the spacer plate 13, it becomes possible to first suction and float the plate material from a fixed position, advance it horizontally by a desired distance, and then lower it to that position, using a single drive device. This eliminates the need for timing alignment for complex two-dimensional movement operations.

I will not repeat the explanation, but make a hole in the plate material at a position that does not interfere with the two vacuum cup positions,
When machining a corner cut or the like, it is clear that it is possible to carry the workpiece back to the starting position without releasing the suction because all the devices are symmetrical in terms of forward and backward movements.
