[Prior art]
As for the present situation, in order to increase the yield of products when processing plate materials, it is better to nest as many products as possible. However, since it may become impossible to identify what is processed, the necessity of entering the product number for the workpiece, that is, the identification marking for identifying each product is screamed. It should be noted that not only numbers but also barcode printing is effective for this identification marking in that it can be used to call a machining program in the next process.
[0003]
Conventionally, as an identification marking method in a plate material processing machine, for example, a turret of a turret punch press as a plate material processing machine is previously mounted with a stamping die, and a processed product is stamped by this stamping die. Alternatively, identification marking (printing) is performed on the processed product after the plate material processing by an ink jet printer. The ink jet printer is a device different from the turret punch press, and is mounted on a carriage movable in the X and Y directions orthogonal to each other on the plane of the processed product, and is moved and positioned by a servo motor. Yes.

[Problems to be solved by the invention]
By the way, in the conventional identification marking method, for example, when identification marking is performed by a stamping die attached to a turret of a turret punch press, there is a problem that the processing time becomes long and the productivity does not increase.
[0008]
Also, when identifying and marking a semi-finished product after processing a plate with an inkjet printer, oil is applied to the workpiece during the processing of the plate with a turret punch press. For example, oil mist or oil on the mold sliding part when tapping is used. There is a problem that the ink may be blocked by oil and not be placed on the plate material because it is attached to the workpiece.
[0009]
Further, although printing is attempted at a predetermined position of the semi-finished product, there is a problem that since the position is already perforated, printing is performed on the table of the ink jet printer apparatus, and the apparatus is soiled.
[0010]
The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a plate material processing machine capable of reliably performing a printing operation in a state of less oil without impeding productivity of plate material processing. Identification in Marking device Is to provide.
[0011]
[Means for Solving the Problems]
The present invention has been made in view of the problems described above, and the lateral position in the X-axis direction of the plate material processing machine (1). Processing machine loading position In addition, a loader body (79) having a loader clamp (87) for holding a plate-like material (W) to be carried into the plate material processing machine (1) is provided long in the Y-axis direction and in the X-axis direction. A material (W), which is provided so as to be reciprocally movable and is taken from the material pallet (PW) by a single take-up device (45) provided at a side position in the Y-axis direction of the loader body (79), is placed. A material loading table (69) that can move horizontally in the Y-axis direction between the single sheet pick-up device (45) and the lower position of the loader body (79) is provided on the material loading table (69). A printing device (89) for printing on the raw material (W) is provided at the end of the loader main body (79) on the single-sheet pick-up device (45) side, and with respect to the plate material processing machine (1). Before carrying in the material (W) In order to perform printing on the material (W), when the material (W) is moved horizontally to the processing machine loading position by the material loading table (69), The printing device (89) performs printing on the material (W) by controlling movement of the loader body (79) in the X-axis direction and movement of the material carry-in table (69) in the Y-axis direction. It is characterized by.
[0012]
Therefore, printing is not performed during or after processing the plate material, but the identification marking is printed on the workpiece with less oil before processing the plate material, so that the printing operation on the workpiece is reliably performed. In addition, since the printing work is performed, for example, before drilling by the plate material processing machine, the printing work is reliably performed without causing, for example, ink for printing to scatter and stain the surroundings.
[0013]
Further, since printing is performed using an essential axis of an operating mechanism used when a work is carried into a plate material processing machine, that is, a control operation mechanism in the XY directions, it contributes to cost reduction.
[0014]
In addition, while the plate material processing is being performed by the plate material processing machine, the printing work is performed on the workpiece to be processed next, so there is little or no loss time due to the printing operation, and the productivity of the plate material processing is reduced. Printing can be done without any problem.

The single-sheet pick-up device 45 includes a frame frame 59 in which a plurality of columns made of, for example, a channel material or the like, and these columns are connected by a plurality of horizontal beam members.
[0034]
A pallet support rail 61 for movably placing the material pallet Pw is provided below the frame body frame 59 so as to be connected to the pallet transfer guide rail 47. On the upper part of the frame frame 59, a single pick unit 65 having a plurality of suction pads 63 for sucking the materials W loaded on the material pallet Pw one by one is provided.

The drive mechanism of the brush table 69 is configured such that, for example, a ball screw that is rotationally driven by a table servo motor 71 is screwed into a nut member provided on the lower surface of the brush table 69.
[0036]
The brush table 69 receives the material W picked up by the single picking device 45 at the material receiving position and supports the material W at the processing machine loading position.
[0037]
A work loading device 73 for loading the material W on the brush table 69 into the turret punch press 1 is provided below the workpiece storage device 39. As the work loading device 73, a loader rail 75 extends substantially horizontally from a lower position of the pallet storage shelf 41 to an upper position on one side (right side in FIG. 1) of the work table 23 of the turret punch press 1. A loader 77 for carrying the material W is provided along the loader rail 75 so as to reciprocate in the left-right direction (X direction) in FIG.
[0038]

Therefore, when the material W placed on the brush table 69 is gripped by the loader clamp 87 and moved in the X direction by the loader servomotor 81, the front side of the material W slides on the upper surface of the brush of the brush table 69. Then, it is carried into the turret punch press 1.
[0041]
In addition, the loader 77 includes an inkjet printer 89 as a printing device, for example, attached to the left end side of the stretch 85 in FIG. It is mounted so that it can move up and down in the direction. Accordingly, the inkjet printer 89 is lowered in the Z direction, and the movement of one or both of the X direction of the loader 77 and the Y direction of the brush table 69 is controlled, so that the material W placed on the brush table 69 is transferred. Printing (identification marking) is performed by the ink jet printer 89. As is apparent from FIGS. 1 and 3, the inkjet printer 89 as a printing device is provided at an end portion on the single-sheet pick-up device 45 side. .
[0042]
Further, a product storage area 91 as an accumulation position is provided adjacent to the left side of the turret punch press 1 in FIG. 1, and the product delivery for carrying out the semi-finished product G processed by the turret punch press 1 to the product storage area 91. A device 93 is provided.
[0043]
As the product carry-out device 93, an unloader rail 95 is provided extending substantially horizontally in the X direction from the position on the upper left side in FIG. 2 of the product storage area 91 to the position above the work table 23 of the turret punch press 1. An unloader 97 is provided on the unloader rail 95 so as to freely reciprocate.
[0044]
A pinion rotated by, for example, an unloader servo motor 101 as an unloader actuator is engaged with a rack provided on the unloader rail 95, and the unloader body 99 is rotated by forward and reverse rotation of the unloader servo motor 101. It is reciprocated in the X direction along the unloader rail 95.
[0045]
Further, a stretch 105 that moves up and down via an elevating cylinder 103 is provided at the lower part of the unloader main body 99, and a plate material gripping device that clamps the semi-finished product G is shown on the right side of the stretch 105 in FIGS. A plurality of unloader clamps 107 are provided. The unloader clamp 107 is configured to be clamped and unclamped by an upper jaw and a lower jaw. The plate material gripping device may be a suction device provided with a vacuum pad or a magnet.
[0046]
Accordingly, the semi-finished product G on the work table 23 of the turret punch press 1 is gripped by the unloader clamp 107 and carried out to the product storage area 91 by the unloader servo motor 101.
[0047]
In addition, a control panel that houses the control device 15 is provided at the upper right in FIG. The control device 15 controls each operation of the turret punch press 1. Further, nesting data is obtained from the turret punch press 1, the position of each semi-finished product G in the material W is recognized, and control is performed so that printing is performed at an appropriate position of each semi-finished product G.
[0048]
Referring to FIG. 6, the control device 15 includes an input device 111 and a display device for inputting data such as work information including nesting data, die information to be used, and a machining program to a CPU 109 as a central processing unit. 113 and a memory 115 for storing input data are connected.
[0049]
The CPU 109 also has a single pick command unit 117 for giving a command to lift a single material W from the material pallet Pw by the single pick unit 65 and place it on the brush table 69 at the material receiving position. Based on the data, the loader 77 is moved and positioned in the X direction in order to print at the position of each semi-finished product G, the brush table 69 is moved and positioned in the Y direction, and the ink jet printer 89 mounted on the loader 77 is moved and positioned in the Z direction. A marking command unit 119 that gives a command to perform printing on the material W on the brush table 69, and a workpiece that gives a command to hold the material W on the brush table 69 by the loader 77 and carry it into the turret punch press 1 after identification marking. The work is carried out by the loading command unit 121 and the unloader 97 after punching. A product unloading command section 123 gives an instruction to discharge the product storage 91 holding the semi-product G of Buru on 23 is connected.
[0050]
The operation in the above configuration will be described. In particular, the desired material pallet Pw is pulled out of the pallet storage shelf 41 by the elevator device 49 and is placed on the pallet support rail 61 of the single-sheet pick-up device 45 through the lowest pallet transfer guide rail of the frame body frame 43. The operation from will be described.
[0051]
In response to a command from the single picking command unit 117, the single picking unit 65 is lowered while the brush table 69 is retracted from the material receiving position of the single picking device 45 to the processing machine loading position of the work storage device 39. One material W is sucked by the suction pad 63 from the material W on the material palette Pw. The single picking unit 65 is raised and the material W is raised to the single picking standby position. Thereafter, the brush table 69 is moved from the processing machine loading position to the material receiving position. The single picking unit 65 is lowered again, and the material W of the suction pad 63 is released and placed on the brush table 69.
[0052]
When the brush table 69 moves horizontally to the processing machine loading position according to the command from the marking command unit 119, the loader 77 is moved and positioned in the X direction based on the nesting data, and the brush table 69 is moved and positioned in the Y direction. Then, the ink jet printer 89 mounted on the loader 77 is lowered in the Z direction, and printing is performed on the material W on the brush table 69. In other words, printing on the material W is performed by controlling the movement of one or both of the X direction of the loader 77 and the Y direction of the brush table 69 and also controlling the lifting operation of the inkjet printer 89 in the Z direction. Done.
[0053]
In addition, since the above-mentioned printing may be lost after being carried out as a semi-finished product G from the turret punch press 1 due to hole processing performed in other processes, it is desirable to print several places on each product. .
[0054]
After the above-described identification marking, the stretch 85 of the loader 77 is lowered by the upper and lower cylinders 83 according to the command of the workpiece loading command unit 121, the material W on the brush table 69 is gripped by the loader clamp 87, and the loader servomotor 81 By driving, the loader 77 moves forward, and the material W is carried into the turret punch press 1.
[0055]
This material W is abutted against the locator pin 35 at the reference position by the origin pad 37 on the work table 23 and positioned at the origin, and is then gripped by the work clamp 31 and moved and positioned by the workpiece movement positioning device 25, and the turret punch. The outline of the semi-finished product G is punched by the processing position K of the press 1 and is cut and separated from the original material W.
[0056]
The semi-finished product G separated from the material W by the command of the product carry-out command unit 123 is clamped by the plurality of unloader clamps 107 of the unloader 97 that moves forward in the right direction in FIGS. The semi-finished product G is lowered by the operation of the elevating cylinder 103 at a position above the storage place 91 and loaded on a predetermined position of the product storage place 91.
[0057]
From the above, since the material W is printed by the inkjet printer 89 before, for example, drilling by the turret punch press 1, the material W is printed without oil such as oil mist, so printing (ink) is performed. It is hard to disappear and the printing work is performed reliably.
[0058]
In addition, a control operation by the servo motors 71 and 81 in the Y direction of the brush table 69 and the X direction of the loader 77 is an essential axis of the operation mechanism of the work loading device 73 used when loading the material W into the turret punch press 1. Since the mechanism is used for printing, it contributes to cost reduction.
[0059]
In addition, while the punching process is performed by the turret punch press 1, the printing work is performed on the material W to be processed next, so that the loss time due to the printing work can be zero (0) or almost eliminated. Printing work is performed without hindering the productivity of plate processing.
[0060]
By the way, the processing time of the turret punch press 1 often takes several minutes, but the tact time of a single piece is usually 30 to 60 seconds, so the next material is processed until the processing of the previous material W is completed. W is waiting on the brush table 69. It is very effective that the printing operation is performed during the standby in that the waiting time is used.
[0061]
In addition, this invention is not limited to embodiment mentioned above, It can implement in another aspect by making an appropriate change. In this embodiment, the turret punch press has been described as an example of the plate material processing machine. However, other punch presses, laser processing machines, and other plate material processing machines may be used.
[0062]
【The invention's effect】
As can be understood from the description of the embodiments of the invention as described above, The present invention According to the above, since the identification marking is printed on the work with less oil before the plate material is processed rather than during or after the plate material is processed, the work for printing on the workpiece can be surely performed. In addition, since the printing operation is performed, for example, before drilling by a plate material processing machine, the printing operation can be performed reliably without, for example, ink for printing scattered and the surroundings being stained.
[0063]
Further, since printing can be performed using an essential axis of an operation mechanism used when a work is carried into a plate material processing machine, that is, a control operation mechanism in the XY directions, cost can be reduced.
[0064]
In addition, while the plate material processing is being performed by the plate material processing machine, the printing work is performed on the workpiece to be processed next, so the loss time due to the printing operation can be reduced to zero, which hinders the productivity of the plate material processing. The printing operation can be performed without any problem.
