[Problems to be Solved by the Invention] However, in the above-mentioned method of lifting and transporting the entire cutting board using a vacuum suction pad, etc., it is necessary to move the conveying device at least to a position beyond the center of the cutting board. , there is a problem that it cannot be applied when there is not enough space above the cutting board.

[0005] Furthermore, due to the structure, it may not be possible to move the conveying device to a position beyond the center of the cut plate, and even if it is structurally movable, the conveying device will be large-scale if the entire cut plate is to be hoisted. There is a problem in that the structure tends to be complicated, especially in the part where cut plates are delivered and delivered.

Furthermore, in the case of conveyance using a roller conveyor, belt conveyor, etc., normally only continuous conveyance is possible, so it is difficult to determine the stopping position of the cutting board, and another handling device is required to transfer the cutting board. There is also the problem.

The present invention has been made to solve the above-mentioned conventional problems, and even if there is not enough space above the cut plate before it is transported, the cut plate can be easily and easily moved to a predetermined position. An object of the present invention is to provide a method for transporting cut plates that can be transported reliably.

[0008]

[Means for Solving the Problems] The present invention provides a method for conveying a cut plate in a horizontal direction, in which the upper surface near the end of the cut plate located on the conveying direction side is sucked and supported, and the edge The above-mentioned problem has been achieved by conveying the cut plate by slightly floating it and dragging it.

[0009]

[Function] In the present invention, the vicinity of the edge of the cut plate on the conveying direction side is attracted and supported from the upper surface, and the edge is slightly raised for conveyance, so that the conveying device is moved in the inner direction of the cut plate. There is no need to infiltrate.

Therefore, according to the present invention, if a space exists only above the vicinity of the end of the cut plate located in the transport direction, the cut plate can be transported reliably.

[0011] Furthermore, since the vicinity of the end of the cut plate is lifted, a turning action occurs, and it is also possible to prevent hanging of two cut plates.

The receiving table 10 is coated with, for example, Bakelite, MC nylon resin, or the like so that the cut plate can easily slide and the cut plate will not be scratched even if the cut plate is dragged.

The first station 12 includes a base 22
It is formed by a conveyor table 26 attached to the surface of the conveyor table 26 via a support 24, and the surface of the conveyor table 26 is designed to allow the cutting board to slide easily and to prevent scratches from occurring on the cutting board even if the cutting board slides. To,
A sliding plate 28 made of, for example, Bakelite or MC nylon resin is attached.

The second to fourth stations 14 to 18 also have the same structure as the first station 12, and the surfaces of the first to fourth stations 12 to 18 are entirely continuous and flat. ing.

The conveyance device 20 includes a truck portion 32 that moves on rails 30 provided on the base 22, and an arm that extends above the first station 12 and is attached to the truck portion 32 via a support portion 34. The basic skeleton is formed from 36, and the entire body is moved by the above-mentioned truck portion 32.

A pinion 42 rotated by a travel drive unit 38 and a reduction gear 40 is attached to the truck unit 32, and the pinion 42 is meshed with a rack 44 fixed to the base 22. . This truck section 32 is moved to the first to fourth stations by rotating the pinion 42 by the traveling drive section 38.
2 to 18, the conveyance direction of the cut plate (direction of the arrow in Fig. 1)
It is said that it is possible to move forward and backward.

The conveyance device 20 also has a first suction section 46 on the opposite side to the conveyance direction of the cut plate, and a second suction section 48 on the side in the conveyance direction. The first suction section 46 is composed of vacuum suction pads 52 attached in a row to a support plate 50 perpendicular to the conveying direction. The support plate 50 is movable up and down by a lift driving section 56 attached to the support frame 54 guided by a guide 58, and the support frame 54 is slidable on a bearing 60 attached to the arm 36. It is attached to the tip of the inserted guide bar 62. Therefore, the first suction section 46 can move forward and backward in the transport direction and can move up and down.

Further, the second suction section 48 is similarly composed of vacuum suction pads 52' attached in a row to a support plate 50' perpendicular to the conveyance direction.
Since a support frame 54' supporting an elevating drive section 56' for elevating and lowering the second suction section 48 is fixed to the end of the arm 36, the second suction section 48 can only move up and down.

Next, the operation of this embodiment will be explained.

First, the transport device 20 is positioned at the rear end above the first station 12, as shown in FIGS. 1 and 2. Next, the guide bar 62 is extended to move the first suction section 46 backward, and the cut plate S placed on the receiving table 10 is removed.
The front end (end on the transport direction side) of the Thereafter, the support plate 50 is lowered by the lift drive unit 56, and the vacuum suction pad 52 is brought into contact with the upper surface of the cutting plate S.

The vacuum suction pad 52 is brought into contact with the upper surface of the end of the cut plate S, and after adsorbing the cut plate S, the support plate 50 is raised by the lift drive unit 56, and the end of the cut plate S is slightly floated. to the state shown in FIG.

Next, the end of the cut plate S is sucked and supported, and while the end of the cut plate S is kept slightly floating, the conveying device 20 is moved in the conveying direction, and the cut plate S is dragged. It is conveyed to any one of the first to fourth stations in such a manner that the After transporting the cut plate S to a desired station, the suction by the first suction unit 46 is released, and the cut plate is placed on the station. Thereafter, the cut plate S is delivered from the station to a desired process.

In addition, when conveying the cut plate to the fourth station 18, after conveying the cut plate to the third station 16 with the edge of the cut plate being sucked by the first suction unit 46, the cut plate is transferred to the first suction unit 46. The transfer device 20 is moved backward, and the second suction unit 48 suctions the same position to move it to the fourth station.

According to the embodiment described above, by suctioning and supporting the upper surface of the cutting plate S near the front end, it becomes possible to easily and reliably transport the cutting plate S to a desired station. .

Therefore, the conveying device 20 does not need to be moved above the cutting plate S, and only the first suction section 46 is moved above the cutting plate S.
The cut plate S can be transported if it can be moved above the front end of the cut plate S, that is, if there is a small space only above the front end of the cut plate S. Therefore, since the transport device 20 and the receiving table 10 do not need to be overlapped in a plane, space can be saved.

In addition, when transporting the uppermost cutting board S from a stack of two or more cutting boards, the end of the cutting board S is lifted, which causes the action of turning the cutting board It is possible to prevent two cutting boards from being lifted at the same time. Therefore, ensure that the cutting board is
It becomes possible to transport sheets one by one.

[0030]Furthermore, since interference or overlapping in the plane direction between the receiving table 10 and the transport device 20 is extremely small, the entire transport equipment can be assembled into a simple configuration.

Furthermore, when transporting the cut plate to the fourth station, which is located first, suction and support for the cut plate are
A second suction section 48 located on the opposite side from the first suction section 46
By changing to , the cut plate can be transported without moving the transport device 20 outside the fourth station. Therefore, if there is other equipment in front of the fourth station 18 (in the transport direction), planar interference between the equipment and the transport device 20 can be prevented, and space can be saved in this respect as well. Become.
