Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a conveying device for conveying a plate material such as a stone plate by a vacuum pad.

[0002]

2. Description of the Related Art Conventionally, large slabs have been cut to process small slabs used for walls, floor decorative plates, and the like. In this method, a large stone plate is placed on a belt conveyor and passed through a cutting device to produce a small stone plate. After cutting in this way, the slab needs to be transported to the next step. Even though the stone plate was cut into small pieces, it was quite heavy, and it was difficult to convey it easily by human power.

Therefore, for example, a transporting device having a vacuum pad at the tip of a folding arm has been considered. This carrying device has the following actions. That is, the arm is manually extended from above the fixed machine base, and it is brought onto a prescribed stone plate placed on the table, and the tip end with the vacuum pad is lowered by the motor, and the plate material is removed by the vacuum pad. Adsorb. Then, the tip portion is raised again by the motor to suspend the stone plate from the vacuum pad. Then, the arm is manually operated again to carry the stone plate to the position where the carriage is located. Then, the tip part is lowered to remove the stone plate from the vacuum pad and lie on a dolly, or the stone plates that have been conveyed horizontally are erected vertically by manpower or power so that they can be conveyed vertically. There is.

[0004]

However, in such a carrying device, the arm must be manually moved every time, and the work efficiency is poor. Moreover, since the machine base is fixed, the range that can be processed is limited because it does not reach a stone plate that is too far away. Furthermore, in the case of manually raising the slab that has been transported to the dolly, it requires a great deal of manual work, and the work efficiency is still poor.

The present invention solves all of these deficiencies all at once, and the purpose thereof is to enable the plate materials to be transported quickly and to be placed vertically or horizontally when they are transported and placed at a predetermined position. Another object is to provide a plate material conveying device.

[0006]

In order to solve the above problems, the present inventor has proposed a beam suspended between a pair of frames placed on a horizontal plane and movable along the longitudinal direction of the frames, A base mounted on the same beam and movable along the longitudinal direction of the beam, a plate material transfer head mounted on the base and movable in a direction orthogonal to the moving direction of the base, and the same plate material transfer head An arm that pivots about one end attached to the head to move, a vacuum pad support that is supported by the other end of the arm, and moves as the arm moves, and a vacuum pad support And a vacuum pad for adsorbing and holding the plate material attached to.

[0007]

With the above arrangement, the beam moves between frames and the base moves between the beams. Further, the plate material conveying head moves in a direction orthogonal to the base. Then, one end is supported by the plate material conveying head and the arm rotates, and the vacuum pad support portion supported on the other end side of the arm changes its position following the rotation of the arm. Then, the vacuum pad attached to the vacuum pad supporting portion changes its position from the horizontal state to the standing state according to the rotation of the arm, so that the plate material attracted to the vacuum pad also stands up.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a plate material conveying device according to the present invention will be described in detail below with reference to FIGS.

As shown in FIG. 1, the plate material conveying device 1 is the same as a pair of metal frames 2 which are extended from a plate material cutting device (not shown) and placed horizontally at a predetermined interval (about 5 m in this embodiment). The skeleton of the device is formed by the metal beam 3 suspended between the frames 2. In the following description of this embodiment, the forward movement means that the beam 3 advances from the plate material cutting device direction, and therefore the forward direction means the direction in which the beam 3 advances. The left and right are referred to as the left and right when viewed from the front.

The frame 2 is composed of a plurality of columns 4 and a frame main body 5 supported by the columns 4 and having a channel-shaped cross section. The beam 3 is composed of a substantially columnar beam body 6 and holding members 7 at both ends of the beam body 6. A geared motor 8 for rotating a pinion (not shown) is arranged above the right holding member 7 so as to mesh with a pinion formed on the frame body 5 (not shown). As a result, the entire beam 3 can be moved forward and backward along the longitudinal direction of the frame 2 by driving the motor 8.

A base 9 is mounted on the beam 3 so as to be slidable in the left and right directions. The base 9 includes a base body 10 inserted through the beam 3 and a guide 1 having a channel cross section.
It is composed of 1 and 1. A geared motor 12 is arranged behind the base body 10 and allows the base 9 to move. Further, a geared motor 13 for moving a plate material carrying head 15 described later is arranged on the upper part of the base body 10.

Inside the guide 11, an elongated plate material conveying head 15 having a substantially columnar shape is mounted. A rack 14 is formed on the rear side of the plate material conveying head 15 so as to extend vertically, and the plate material conveying head 15 is vertically movable along a guide 11 in a meshing relationship with a pinion (not shown). There is. The pinion is driven by a geared motor 13 provided on the upper part of the base body 10 and, as a result, is rotated. An angled connecting plate 17 is attached to the lower portion of the plate material conveying head 15. A gear box 19 is formed below the plate material conveying head 15 with the connecting plate 17 interposed therebetween. Further, a geared motor 18 for rotating an arm 20 described later is mounted on the uppermost end of the plate material conveying head 15. The driving force of the geared motor 18 is transmitted to the gear box 19 via the plate material conveying head 15. Connection plate 1
Proximity switches 27 and 28 are arranged on the rear left side of the gear box 7 and the front left side of the gear box 19, respectively.
Both proximity switches 27 and 28 are detection plates 2 described later.
By detecting 9 and 30, the geared motor 18 in the on state is turned off.

An air cylinder 16 is arranged along the plate material carrying head 15 to compensate for the lack of thrust when the plate material carrying head 15 is moved. A pair of arms 20 extends so as to sandwich the gear box 19 from the left and right. One end 21 of the arm 20 is connected to a gear (not shown) in the gear box 19, and the geared motor 18
Is transmitted to the gear box 19, and as a result, the arm 20 rotates about the one end 21 as a rotation center. A detection plate 29 for detecting the position of the proximity switch 28 is arranged near the one end 21 of the arm 20. Further, another detection plate 30 is arranged at a position shifted by 90 degrees from the detection plate 29, and the proximity switch 27 detects the position.

A vacuum pad support 22 is mounted near the other end of the arm 20. A geared motor 24 is attached to one end of the vacuum pad supporting portion 22, and a vacuum pad 25 for adsorbing and holding a plate material is attached to the other end thereof. The vacuum pad 25 has a large diameter 25 as shown in FIG.
A pair of pads of a and a small diameter 25b face each other, and the pad rubber portion is made of neoprene sponge. The vacuum pad 25 is designed to rotate on the same plane as the pad surface by driving the geared motor 24. Large diameter 25
Each pad of a and the small diameter 25b is sucked and exhausted by a separate vacuum pump.

Arm 20 and vacuum pad support 22
Is in an orthogonal state with the arm 2 as shown in FIG.
Vacuum pad support 2 with 0 held horizontally
2 will be positioned vertically. Then, in this state, the vacuum pad 25 faces the pad surface directly below in parallel with the arm 20.

In this apparatus, an operator operates an operation panel (not shown) to turn on / off each motor to determine the position of the vacuum pad 25. Further, the same operation panel is operated to suck and exhaust the vacuum pad 25. At the time of operation, the operator needs to confirm whether or not the vacuum pad 25 has descended to the central portion of the stone plate S from a remote position where the operation panel is installed. Therefore, two convex mirrors 31 and 32 are attached to the base 9, and an operator can accurately visually recognize the positional relationship between the vacuum pad 25 and the stone plate S from the position of the operation panel by the convex mirrors 31 and 32. it can.

Next, the operation of the present embodiment thus constructed will be described. First, the stone plate S, which has been cut into small pieces by the cutting device, is placed on the table T and discharged. Then, the operator holds the vacuum pad 25 above a predetermined stone plate (the stone plate S at either end of the front row).
Operate the control panel so that It is assumed that the arm 20 and the vacuum pad 25 are held horizontally when the plate is first taken.

First, the beam 3 is moved to the position of the stone plate S arranged in the front row, and then the base 9 is moved along the beam 3.
Is moved and finely adjusted while looking at the convex mirrors 31 and 32, and the vacuum pad 25 is operated so as to come directly above the center of the stone plate S conveyed. Then, the plate material conveying head 15 is moved down to be brought into contact with the stone plate S. When a constant load due to contact with the stone plate S is detected by a torque limiter (not shown) attached to the motor shaft, the plate material conveying head 15 is stopped by detecting it. Then, the inside of the vacuum pad 25 is evacuated to adsorb the stone plate S. Then, the plate material conveying head 15 is raised again while adsorbing the stone plate S. After inputting the exhaust switch for exhausting the inside of the vacuum pad 25, the vacuum pad 25
It is necessary to prevent the plate material carrying head 15 from rising until the inside is completely exhausted in order to prevent danger. Therefore, the vacuum pad 25 is provided with a pressure switch (not shown) that works in conjunction with a switch for raising the plate material conveying head 15 so as to detect the exhaust gas inside the vacuum pad 25. When the pressure in the vacuum pad 25 becomes lower than a certain atmospheric pressure, a switch for raising the plate material conveying head 15 can be input only when the pressure switch detects it.

When it is confirmed that the stone plate S has been suspended, the beam 3 and the base 9 are moved again, and this time the vacuum pad 25 and the adsorbed stone plate S head toward the front stone plate mounting carriage H direction. To operate. Then, it is temporarily stopped before the carriage H.

By the way, if the stone plates S are stacked side by side and stacked, they will be cracked or damaged. Therefore, it is necessary to place the cut stone plates S cut out in this way vertically on the carriage H.

However, as shown in FIG. 3, the stone plate S is adsorbed by the vacuum pad 25 and held horizontally until this stage. Therefore, the arm 20 is rotated about its one end 21 so as to hold it vertically.

As shown in FIG. 4, the arm 20 is gradually rotated to move the vacuum pad supporting portion 22 so as to pass under the gear box 19, and the arm 20 is rotated immediately before the stone plate S becomes vertical. Try to stop the movement.

Further, in this embodiment, the slab S is cut into a rectangle that is long in the front and rear direction, and it is preferable to lay it horizontally instead of vertically to consider the stability and the work of the next step. Therefore, the vacuum pad 25 itself is rotated within the plane of the pad. That is, as shown in FIG. 6, the stone plate S held substantially vertically is rotated 90 degrees at that position to be placed horizontally.

Then, the beam 3 and the base 9 are moved again so that the stone plate S is just placed in the carriage H, and fine adjustment is performed. After the fine adjustment is finished, air is again sucked into the vacuum pad 25 and the stone plate S is removed from the vacuum pad 25, and the stone plate S leans toward the carriage H by its inclination and leans on the back plate of the carriage H as well.

Here, as shown in FIG. 5, when the stone plate S (the arm 20 is also vertical in the longitudinal direction) is in a vertical state,
The detection plate 29 comes to detect the proximity switch 28. Then, receiving the detection signal, the geared motor 1
8 is turned off, and the arm 20 cannot rotate any more. As a result, the upper end of the stone plate S is located at the air cylinder 16
It does not come into contact with such members.

Next, in order to carry the next stone plate S, the arm 20 is rotated in the opposite direction, and the beam 3 and the base 9 are moved. When the arm 20 is rotated in the opposite direction, the arm 20 and the vacuum pad 25 need to be horizontal. Therefore, as shown in FIG.
Also, when the vacuum pad 25 becomes horizontal, the detection plate 30 detects the proximity switch 27. Upon receiving this detection signal, the geared motor 18 is turned off, and the arm 20 does not rotate any more. As a result, the arm 20 and the vacuum pad 25 are in a horizontal state and descend as they are, so that the vacuum pad 25 conforms to the flat surface of the stone plate S and can be sucked smoothly.

With this structure, the present embodiment has the following effects. (1) By moving the beam 3 and the base 9, the vacuum pad 25 can be swiftly attached to any slab S over a wide range. Further, by changing the length of the beam 3 and the base 9, it can be easily applied to a large-scale cutting device. (2) By rotating the arm 20, the position of the stone plates S held in the horizontal state can be easily changed in the vertical direction, and the stone plates S can be stacked horizontally or vertically. (3) Since the vacuum pad 25 itself can be rotated, the stone plate S can be placed horizontally or vertically. (4) Proximity switches 27, 28 and detection plates 29, 30 for detecting the proximity switches are arranged according to the position of the arm 20. Therefore, when the stone plate S is placed on the carriage H, the upper end of the stone plate S does not accidentally come into contact with a member such as the air cylinder 16. Further, when the arm 20 is returned to the horizontal position, the arm 20 and the vacuum pad 25 are automatically placed in the horizontal state, so that the vacuum pad 25 is simply lowered onto the stone plate S to match the flat surface of the stone plate S. (5) Vacuum pad 25 has a large diameter 25a and a small diameter 25b
Each of them is constituted by a pair of pads, and the large diameter 25a and the small diameter 25b are separately sucked and discharged by respective vacuum pumps. Therefore, the stone plate S
When is small, it is possible to adsorb only with a pad having a small diameter 25b. Further, even if either the large diameter 25a or the small diameter 25b protrudes from the stone plate S, it can be adsorbed by the other pad that does not protrude. (6) The vacuum pad 25 can be surely made to correspond to the stone plate S by visually recognizing the convex mirrors 31, 32,
In addition, it is always easy to check around the device.

Although one embodiment of the present invention has been described in detail above, the present invention is not limited to the above embodiment and can be implemented by changing to other modes. For example, in the above embodiment, it was manually operated, but it is also possible to create software and operate it under the control of a computer.

Further, although the beam 3 and the base 9 are moved in the above-described embodiment in the relationship of the rack and the pinion, it is also possible to use the belt and the pulley or the timing belt. Further, in the above-described embodiment, the arm 20 is rotated to move the stone plate S from the horizontal state to the standing state, but it is also possible to place the stone plate S on the dolly H while lying down. In addition, the present invention can be applied to wooden boards other than stone boards, and the present invention can be freely modified and implemented without departing from the scope of the invention.
