(Prior Art) A pande press is equipped with a bouple extending in the left-right direction and a clamp device for positioning the plate material on the table by moving it in the front-rear and left-right directions. Conventionally, before gripping a plate with a clamp device, in order to determine the origin position of the plate carried into the above-mentioned table in the front and back and left and right directions,
The clamping device includes a first positioning member for positioning the origin of the plate in the front-rear direction, and a second positioning member on one side (for example, the left side) of the table for positioning the origin of the plate in the left-right direction. is the provision. In order to bring the plate material located at an appropriate position on the table into contact with the first positioning member and the second positioning member, a plate material puller equipped with a rotatable pulling pad is provided near the second positioning member on the table. The loading device is installed.

In order to carry the plate materials to appropriate positions on the table, a plate material loading position 5A is provided on one side (for example, the left side) of the table for carrying the plate materials. Here, place the plate material loading device on the other side (for example, the right side) opposite to the second positioning member.
The reason why the table was not installed is because the table extends in the left-right direction, and if the plate material carrying device is provided on the other side of the table, the conveying stroke of the plate material will be longer. In addition, the plate Ul [input device includes a guide member extending in the left-right direction at the lower position of the table, and a plate holding member provided for holding the plate on a movable body movably provided on the guide member. It is equipped with

To explain the function of the conventional origin positioning of the plate material with the above configuration, the plate material is loaded at an appropriate position and held by the plate holding member, and while the plate material is being held, the plate material is held. Raise the member. Then, the plate holding member is moved in the left-right direction via the movable body to lower the plate holding member positioned vertically above the table and release the holding state between the plate and the plate holding member. As a result, the plate material is carried to an appropriate position on the table.

The original position of the plate was determined by bringing it into contact with a first positioning member and a second positioning member.

(Problem to be Solved by the Invention) However, in order to determine the origin position of the plate material, the plate material is carried from one side of the table to the other side, and the plate material is moved in that direction. This is troublesome, and there is a problem that the conveyance stroke differs depending on the size of the plate material, and the conveyance stroke becomes longer for the plate material stretched in the left-right direction.

SUMMARY OF THE INVENTION An object of the present invention is to provide a method for locating the origin of a plate material that can solve the above-mentioned problems, and a punch press and a plate carrying device used in the method for locating the origin of a plate material.

[Structure 1 of the Invention (Means for Solving the Problems) In order to solve the conventional problems as described above, the present invention provides a method for positioning the origin of a plate material, and a method for positioning the origin of the plate material in the front and back direction. After positioning the clamp device equipped with the first positioning member on the table of the punch press (approximately 1 point near the center in the left-right direction), the clamp device is moved from one side of the punch press to the other side in the left-right direction.
: In order to determine the origin position in the left and right direction, the plate material to be carried in is brought into contact with a second positioning member provided near the center (=J) of the table in the left and right direction, and is also brought into contact with the first positioning member. This allows the origin position of the plate material to be determined.

In the punch press used in the above-mentioned method for locating the origin of a plate material, a clamping device equipped with a first positioning member for locating the origin position of the plate material in the left-right direction is provided on the table of the punch press so as to be movable in the front-back and left-right directions, and A second positioning member for positioning the origin of the plate material in the front-rear direction is provided near the center of the table in the left-right direction so as to be freely retractable from the upper surface of the table.

The plate material carrying device used in the method for determining the origin of the plate material described above is provided with a guide rail extending from one side of the table in the left-right direction to the other side at a position above the table, and a movable body movably provided on the guide rail. The plate holding member for holding the plate can be moved up and down, and can be moved forward and backward.
It is also provided so that it can be rotated and fixed horizontally.

(Function) In the above configuration, first, with the plate holding member fixed in a non-rotatable manner, the plate holding member is lowered and the plate at an appropriate position is held by the plate holding member. Next, the plate holding member is raised until the plate is located at a higher level than the top surface of the table, and the movable body is moved from one side of the table to the other side via the guide rail. Furthermore, before the plate material is carried onto the table, the clamping device is positioned near the center of the table in the left-right direction.

When the plate is located near the first and second positioning members due to the movement of the movable body, the plate holding member is lowered until the plate is located at approximately the same height as the top surface of the table, and the plate is removed. The holding member is left in a freely rotatable state. Then, by further moving the movable body toward the other side, the plate material is brought into contact with the second positioning member, and the plate material holding member is moved forward toward the first positioning member. 1. Bring it into contact with the positioning member. This allows the origin position of the plate material to be determined, and the plate material whose origin position has been determined is gripped by the clamp device. Since this sharpening plate holding member is rotatable, even when the predetermined abutment surface of the plate is not parallel to the second positioning member and the first positioning member, the predetermined abutment surface of the plate is attached to the second positioning member and the first positioning member. A predetermined contact surface of the plate can be brought into contact with the second positioning member and the second positioning member relatively easily in parallel with the first positioning member.

In order to carry the plate material W into the turret punch press 1 and to determine the origin position of the plate material W, the plate material is carried into the right side of the turret punch press 1 as shown in Figs. 3, 4, 5, and 6. A device 45 is provided.

Referring to FIGS. 3, 4, 5, and 6, for details of the plate material carrying device 45, a kite rail/17 is installed above the movable table 37 via a support (not shown). It extends from the right side in the left-right direction (in the left-right direction in FIGS. 3 and 4, and in the front and back directions toward the plane of the paper in FIGS. 5 and 6). This guide rail 47 is provided with a first moving body 49 that is movable in the left and right directions, and is operated by appropriately operating the drive motor 51 to rotate the rollers 53 as appropriate. The first moving body 49 is capable of moving in the left-right direction. Note that the details of the configurations of the drive motor 51 and the rollers 53 are well known, so the details will be omitted.

A plate-shaped second moving body 55 is provided on the first moving body 49 so as to be movable up and down via a guide bar 57. In order to move the second moving body 55 up and down, the first moving body 49
A fluid cylinder 59 is attached at an appropriate position, and a piston rod 61 that can freely protrude downward from this fluid pressure cylinder 59 is attached to the second moving body 55 at an appropriate location. The left side surface of the second movable body 55 has a front and back direction in the front and rear directions in FIG. 3, a top and bottom direction in FIG.
A guide member 63 extending in the left-right direction in FIGS.
This guide member 63 is provided with a third moving body 67 having a running portion 65 so as to be movable in the front and rear directions. A barrel for moving the third moving body 67 in the front and back direction,
A fluid pressure cylinder 69 is attached to an appropriate position of the second moving body 55 via a support bracket 71, and a piston rod 73 that can freely protrude forward from this fluid pressure cylinder 69
is attached to the recess 75 of the third moving body 67.

The third moving body 67 is provided with seven plate holding members each having a plurality of vacuum pads 77.

More specifically, a rotating member 85 having a rotating shaft 83 is rotatably provided on the support portion 81 of the third moving body 67, and a guide portion 87 provided integrally with the rotating member 85 has an engaging portion. 8
The plate material holding member 79 integrally provided with 9 is engaged with the plate material holding member 79. Then, when the plate +J' W held by the seven plate holding members via the vacuum pad 77 comes into contact with the first and second positioning members 39 and 41, the plate holding members 7
In order to soften the impact of 9, a buffer cylinder 91 is provided at an appropriate position on the plate holding member 79, and -14= screws 1 to 93 that can freely protrude to the right from this buffer cylinder 91 are attached to the rotating member 85. Install it in the appropriate position.

As is clear from the above configuration, the plate holding member 79 is
It can move in the left and right direction via four first moving bodies, and also includes a second moving body 55, a fluid pressure cylinder 5
9 can move up and down, and can move back and forth via a third moving body 67 and a fluid pressure cylinder 69. Furthermore, a plate holding member 79
is rotatable with respect to the third moving body 67 via the rotating shaft 83 in the rotating member 65 .

A fixing device 95 is provided to integrally fix the rotatable plate holding member 79 to the third moving body 67. More specifically, a fixed shaft 99 extending upward is erected on the protrusion 93 of the plate holding member 79. In order to suppress and fix the seven fixed shafts to a fixing member 101 integrally provided on the second movable body 55, a support bracket 103 integrally attached to the second movable body 55 is provided with a support bracket 103 for fixing. A cylinder 105 is provided, and a piston rod 107 that can freely protrude rearward from the fixing cylinder 105 is provided with a pressing pad 109 that can press the fixed shaft 99 .

With the above configuration, by appropriately operating the fixing cylinder 105 to cause the piston rod 107 to protrude rearward and press the fixing shaft 99 to the fixing member 101 with the press pad 109, the plate holding member 79 can be moved to the three moving bodies. 67
It can be integrally fixed to the body and rendered unrotatable.

The operation of this embodiment will be explained based on the above-described configuration.

First, operate the fixing device 95 appropriately to hold the plate holding member 79.
is integrally fixed to the third moving body 67, making it unrotatable. Then, by appropriately operating the five fluid cylinders to lower the seven plate holding members, and by appropriately operating the plurality of vacuum pads 77, the uppermost part of the plurality of plate materials W loaded at appropriate positions is lowered. Board material W
is held by seven plate holding members.

Next, the fluid pressure cylinder 59 is operated appropriately to position the plate material W held by the plate material holding member 79 at a position higher than the upper surfaces of the fixed table 35 and the movable table 37. Then, the first moving body 49 is moved to the left, and the plate holding member 79 holding the plate W is moved to the left. Furthermore, before carrying the plate material W into the fixed table 35 and the movable table 37, the first carriage 27 is positioned in front of the fixed table 35 and the movable table 37, and the clamp device 3
The second carriage 31 with the second carriage 1 is positioned near the center of the first carriage 27 in the left-right direction.

When the plate material W held by the plate material holding member 79 is located in the vicinity of the first and second positioning members 39.41 due to the movement of the first moving body 49, the fluid pressure cylinder 59 is operated appropriately to move the plate material W. While lowering the plate holding member 79 until it is located at approximately the same height as the top surface of the fixed table 35,
The fixing device 95 is operated appropriately to keep the plate holding member 79 in a freely rotatable state.

Then, by further moving the first moving body 49 to the left, the left side surface of the plate W can be brought into contact with the second positioning member 41. The front surface of the plate W can be brought into contact with the first positioning member 39 by appropriately operating the fluid pressure cylinder 69 to move the plate holding member 79 forward toward the first positioning member 39 . Thereby, the origin position of the plate material W can be determined, and the plate material W located at the origin position is gripped by the clamp device ff131. At this point, since the plate holding member 79 is rotatable, the left side of the plate W is connected to the positioning member 41 and the plate W.
Even when the front side surface of the plate W is not parallel to the first positioning member 39, the left side and front side of the plate W are made parallel to the first and second positioning members 39, 41, so that the left side and front side of the plate W are parallel to each other. The side surface is the second positioning member 41, the first positioning part +1
39 can be brought into contact with it relatively easily.

Note that when the origin position of the plate material W has been determined and the desired punching process has been completed, the clamping device 31 that grips the plate material W can be moved in the front and rear and left and right directions via the first and second carriages 2733 to prevent the plate material W from protruding in advance. The plate material W can be brought into contact with a certain second positioning member 41 to determine the position for carrying out.

Therefore, when carrying out the plate material W to the left side of the movable table 37, the position of the left side surface of the plate material W is fixed, and a known carrying-out means is used as appropriate without providing a sensor to detect the left side surface of the plate material. It is possible to detect the plate material W.

According to this embodiment, since the second positioning member 41 is provided near the center in the left-right direction of the fixed table 35 of the turret punch press 1 so as to be freely retractable from the upper surface of the fixed table 35, the plate material W can be moved. By moving the table 37 from the right side in the left-right direction to the left, the second positioning member 711 and the first positioning member 39 are attached to the plate material W.
The origin position can be determined by bringing the two parts into contact with each other.

Therefore, since the plate material W, which was first moved from the right side to the left direction, is not moved from the left side to the right direction, it is relatively less difficult to determine the origin position of the plate material W, and, Even if the dimensions of the plate material W change, the conveyance stroke does not change.

Further, since the plate holding member 79 can be rotated and fixed horizontally, the origin position of the plate W can be appropriately determined.

It should be noted that the present invention is not limited to the description of the embodiments described above, and can be implemented in various other forms by making appropriate changes.

[Effects of the Invention] As understood from the above description of the embodiments, according to the present invention, the second positioning member is placed on the upper surface of the table near the center (=I) in the left-right direction of the table of the punching press. By moving the plate material from one side to the other side in the left-right direction of the table, the plate material is brought into contact with the second positioning member and the first positioning member. , it is possible to determine the origin of the plate material.Therefore, unlike in the past, the plate material moved from the - mouth side to the other side is not moved from the expansion side to the one side direction. The origin positioning is relatively less troublesome, and the conveying stroke does not change even if the dimensions of the plate material change.

Further, since the plate holding member can be horizontally rotated and fixed, the origin of the plate can be appropriately determined.
