[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a cutting method and a cutting apparatus.
[0002]
[Prior art]
Conventionally, a material such as a long flat bar is stored in a three-dimensional shelf, and a desired material is taken out from the storage shelf by a conveying device such as a crane as a work material, for example, a circular saw as a cutting machine, for example. The workpiece is placed on a feeding device for carrying the work material to the board, and is moved and positioned to the cutting position of the circular saw by this feeding device and then cut by the circular saw.
[0003]
[Problems to be solved by the invention]
By the way, in the conventional cutting processing apparatus, the reference position of the work material is set in the process in which the work material is stored in the storage shelf, removed from the storage shelf, placed on the feeding device, and carried into the cutting machine. Since this is done without consideration, it is necessary for the operator to check the reference position of the work material each time the work material is cut by a cutting machine. Therefore, it has not been possible to configure a cutting device that automatically cuts through all the steps.
[0004]
The present invention has been made in order to solve the above-described problems, and the object thereof is to provide a reference for the work material in all processes in which the work material is stored in the storage box and then discharged and cut by a cutting machine. It is an object of the present invention to provide a cutting method and a cutting device that can be cut into a cutting machine without changing the position.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, the cutting method of the present invention according to claim 1 is characterized in that the reference end of the work material is abutted against the supply abutment reference surface of the material mounting portion provided in the work material supply apparatus. Place the work material on the material placement part,
By moving the material placement portion forward to the supply station of the three-dimensional stocker, the material placement portion is cut to the stocker abutting reference surface of the stocker located at the supply station among the many stockers of the three-dimensional stocker. Place the reference end of the material in contact, and supply the work material to a large number of stockers of the three-dimensional stocker by repeating sequentially,
A large number of stockers of the three-dimensional stocker are circulated and rotated to lower a desired stocker to a delivery station of the three-dimensional stocker, and a work material transport device for carrying a work material to the cutting machine is located at the delivery station. The work material of the desired stocker is received after being moved to the position of the stocking reference surface for the stocker.
The work material is conveyed until the reference end of the received work material is located at a predetermined position on the work material conveying device,
By lowering the work material conveying device, the reference end of the work material at a predetermined position is placed against the material feeding reference surface of the lower material feeding device, and placed.
The placed work material is fed to a cutting machine by the feed device and cut.
[0006]
Therefore, when the work material is supplied to the three-dimensional stocker by the work material supply device, the reference end of the work material is positioned on the supply abutting reference surface of the work material supply device, and then the work material reference The end is abutted against the stocker butting reference surface of each stocker of the three-dimensional stocker and positioned. The work material of each stocker is received by the work material conveying device and then transported to a predetermined position, and the reference end of the work material is abutted against the feeding reference surface of the material feeding device for positioning and cutting. The material is sent to the machine. The reference end of the work material is always carried to the cutting position of the cutting machine without being changed, and is cut.
[0007]
According to a second aspect of the present invention, there is provided a three-dimensional stocker capable of storing a number of work materials by circulatingly driving a number of stockers having a stocking reference surface for a stocker that abuts a reference end of the work material. A supply station for supplying the work material to the three-dimensional stocker and a delivery station for discharging the work material from the three-dimensional stocker are provided.
A stocker abutting reference of a stocker having a material placing portion having a supply abutting reference surface that abuts a reference end of the work material and the work material placed on the material placing portion located at the supply station A work material supply device provided with the material placing portion so as to be able to move forward and backward to strike the surface,
Provided with a work material conveying device that projects to the stocking reference surface for the stocker that descends to the unloading station and can move forward and backward so that positioning is possible and conveys the work material of the stocker of the unloading station to a predetermined position;
The feed material abutting reference surface that abuts the reference end of the work material conveyed to the predetermined position, and the work material positioned on the feed material abutting reference surface is fed to the cutting machine. A material device is provided.
[0008]
Therefore, the operation is the same as that of the first aspect, and when the work material is supplied to the three-dimensional stocker by the work material supply device, the reference end of the work material is the abutting reference for supply of the work material supply device. Then, the reference end of the work material is abutted against the stocker abutting reference surface of each stocker of the three-dimensional stocker and positioned. The work material of each stocker is received by the work material conveying device and then transported to a predetermined position, and the reference end of the work material is abutted against the feeding reference surface of the material feeding device for positioning and cutting. The material is sent to the machine. The reference end of the work material is always carried to the cutting position of the cutting machine without being changed, and is cut.
[0009]
According to a third aspect of the present invention, there is provided a cutting apparatus according to the second aspect, wherein the workpiece conveying device is provided so as to be movable up and down so as to move the workpiece up and down, and the feeding device is arranged in the workpiece. A plurality of stepped rollers provided with an abutting reference surface for feeding material are provided at an inclination while being positioned below a predetermined position of the cutting material conveying apparatus.
[0010]
Accordingly, since the stepped roller is provided below the predetermined position of the work material conveying device, the work material at the predetermined position is surely placed on the stepped roller when the work material conveying device is lowered. In addition, since the stepped roller is inclined, the work material is reliably abutted against the feeding reference surface by its own weight.
