Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an unmanned machine for processing a plate material to produce a sheet metal product.

[0002]

2. Description of the Related Art In order to produce a product made of sheet metal, the sheet metal is cut and processed according to the developed shape of the product, and the product is completed by bending or welding. A laser beam machine, a punching machine, or the like is used as a plate material processing apparatus. To perform this plate processing automatically,
There is a need for a device that automatically supplies a plate material as a raw material to a processing machine and automatically carries out the processed plate material from the processing machine. There are many types of plate materials such as plate thickness and material, and equipment for preparing these various types of materials is required. For example, by using a three-dimensional warehouse and a stacker crane, it is possible to efficiently store a wide variety of plate materials and supply them to the processing machine as needed.

For example, JP-A-60-247422, JP-B-3-47701, and JP-A-3-3632
No. 8 discloses a sheet metal processing system including a sheet metal processing line including a machine tool such as a punch press machine and a shearing machine, a three-dimensional warehouse, and a stacker crane. Further, Japanese Patent Application Laid-Open No. 3-196947 discloses a system in which a plate material stored in a shelf of a three-dimensional warehouse is moved to a shelf closer to a transfer device during idle time of a processing machine.
Japanese Unexamined Patent Publication (Kokai) No. 58-93528 discloses a material feeding device that feeds a magazine carrying blanks from a stacker crane to a blank feeding device provided on the side of a transfer press by a conveyor.

[0004]

In all of the above-mentioned publications, the sheet materials are stacked on a pallet and transferred by a stacker crane, and the uppermost sheet material is processed by a vacuum pad or the like. It uses a structure in which plates that are supplied or processed are loaded back onto a pallet by a gripper.
Therefore, it does not disclose the technique of using the remaining residual material obtained by cutting the product from the plate material of a fixed length as a raw material again. If the remaining materials can be reused as materials,
The material yield can be improved and the cost can be reduced. Further, if the processed plate material can be automatically returned to the three-dimensional warehouse side, it is possible to realize long-time continuous processing by unmanned operation. In order to manage the remaining materials having different shapes one by one, it is not possible to adopt a system for stacking plate materials on a pallet, and it is necessary to prepare a pallet for accommodating each remaining material. The present invention provides equipment that makes effective use of residual materials and enables continuous processing for a long time by unmanned operation.

A separation station having a first separator and a second separator for separating an arbitrary pallet from a multi-stage pallet; and a plate material processing device arranged adjacent to the separation station,
A first unloading station and a second unloading station arranged on both sides of the plate material processing apparatus, and a plate material is taken out from the first separator of the separation station and loaded into the plate material processing apparatus, and the processed plate material is first. Device for unloading to the unloading station or the second unloading station, a control device for managing a warehouse in a three-dimensional warehouse, a control device for controlling a processing line, and a CAD / CAM system for creating a processing program from drawing data. A control device that centrally controls the entire equipment is provided.

[0006]

[Function] The processed plate material is automatically returned to the side of the three-dimensional warehouse as required and used again as a material. The loading and unloading of plate materials to and from the processing machine is completely automated, and unmanned processing continues for a long time.

The pitch of 04 corresponds to the pitch of the fork, and the stopper 205 positions the plate material to be housed. Pallet 20
Since 0 is configured as described above, it is possible to construct a multi-pallet by stacking the pallets 200 accommodating the standard length material and the residual material vertically. Instead of the above pallet, for example, a plate material may be placed on a thin plate base having a honeycomb structure and supplied to the laser processing apparatus together with the base to process the plate material on the base.
In this case, since the work after processing is supported on the base, a joint for temporarily connecting the product and the residual material is unnecessary.

As described above, this equipment has a separation station for separating an arbitrary pallet from the stacked multi-pallets and a mechanism for scooping out the plate material in the pallet by the transfer device having two forks. It is possible to reliably handle different residual materials. Since the separation station also includes a lifter having a vacuum pad, plate materials directly laminated on the pallet can be easily handled. With the above configuration, a non-magnetic work such as plastic or ceramic can be handled like a magnetic work. The transfer device is provided with two forks, and the first fork carries the work before the next process and the second fork carries the worked work at the same time, so that the tact time is shortened.

The management controller 95 gives a command to the line controller 94 according to a schedule.
The warehouse controller 92 has functions of material inventory management, product management, shipping operation, receiving operation, and information update, and controls the stacker crane 30. The material inventory management here means that when a shelf number is specified, the material name, material, and quantity can be managed as shelf information associated with it, and product storage is likewise specified by the shelf number. It manages information such as work names, materials, quantities, and customers.
Therefore, the warehouse controller 92 issues a shipping instruction and a material name, the number of sheets, a re-storage, and an empty space instructed by the data of any one of the material name, the order number, and the shelf number instructing the location of the shelf for the manual loading / unloading operation. There is a storage command that gives storage data, and an operation command is given to the stacker crane 30 in response to a material request from the line controller 94, and the ordered pallet is conveyed.

The line controller 94 gives a command to the laser processing machine 70 and the carrier according to the processing schedule transferred from the management controller 95. The line controller 94 has the functions of requesting materials to the stocker, transferring a carrier control program, instructing to start processing, requesting pallet storage, and operation status confirmation. That is, a material such as SPHC 2.3 is requested to the warehouse controller 92 from the data input in the processing schedule, and a carrier is instructed to supply the material to the laser processing machine 70, and at the same time, the processing program is transferred to the laser processing machine 70.

There are many types of plate materials to be processed, but standard size materials are supplied in a state of being stacked on a pallet base as usual. Remaining materials and the like having different shapes and dimensions are housed in pallets one by one and supplied as a multi-pallet in which pallets are stacked. This equipment is C
Since it is equipped with an AD / CAM system and carries out plate cutting by CAD / CAM and creates a machining program, the shape and dimensions of the residual material after plate cutting can also be managed by CAD / CAM and used as the material for the next process. Since it is equipped with a device that separates any pallet from the multi-pallet and takes out the plate material from the pallet or returns the plate material, it is possible to effectively use the remaining material, improve yield, improve profitability and It is possible to centrally control existing plate materials and achieve unattended automatic processing for a long time.
