Description

  The present invention relates to a plate material storage system that loads and stores plate material products processed by a punch press or its peripheral device, such as punching and forming.

  Conventionally, flat plate products processed by punch presses and peripheral devices such as punching and forming are machined with the product part that has been cut out by punching or the like being joined to the slag part by a micro joint. They were taken out and piled up directly in order or separated into individual products and then piled up directly as well.

  As described above, when the plate material products are directly stacked, there is a problem that the load balance is deteriorated and collapses when the projecting portion is uneven. In order to solve this problem, there has also been proposed a structure in which a plurality of mounting table members each having an opening at the bottom are stacked, and several plate material products are stacked on each mounting table member (for example, Patent Document 1). .

In addition to this, there has been proposed one in which plate products are stored in a non-overlapping state on a plurality of drawer-type shelves provided in a box-shaped storage member (for example, Patent Document 2).
JP 2004-123276 A JP 11-59813 A

When directly stacking plate products having molded parts, there are problems that the front and back surfaces of the plate products are damaged, the shape of the molded parts is crushed, and the load balance is deteriorated and collapsed.
The one that stacks the mounting table members disclosed in Patent Document 1 can prevent the collapse of the load balance and collapse, but since several plate products are directly stacked, the plate products are placed on the front and back surfaces between each other. It is not possible to sufficiently prevent the damage.
Since the drawer type disclosed in Patent Document 2 is placed on a shelf without overlapping plate products, problems such as scratches are eliminated, and there is no problem that the load balance is deteriorated and collapses. However, when a plate product is stored from a plate processing machine, a mechanism for taking in and out a drawer-type shelf is required for automation.

The object of the present invention is to store flat plate products having protruding molded parts so that the plate products are not in direct contact with each other and are not damaged or crushed. It is an object of the present invention to provide a plate material storage system that does not require an apparatus and can simplify the configuration.
Another object of the present invention is to eliminate the need for extra space on the side of the shelf position and to save space.
Still another object of the present invention is to save space in the height direction.

The unloader sucks the plate product with the suction pad by the plate processing machine, travels to above the shelf at the horizontal position of the plate stocker, and then releases the suction to place the plate product on the shelf. At this time, if the unloader is of a suction type, the unloader needs to be moved up and down to bring the suction pad into contact with or away from the plate product. However, since each shelf above the shelf in the horizontal position is flipped up, there is no obstacle, and a space for moving the unloader up and down for releasing the suction is secured. Therefore, it is not necessary to secure an extra space on the side of the shelf position, and it is possible to save space in the width direction for the plate stocker. In addition, the unloader places the plate product on the shelf in the horizontal position, and then sets the shelf in the raised state on the upper level to the horizontal position. Yes.

In the present invention, each shelf can be switched between a storage position as the use position and a retracted position pulled out from the storage position, and the unloader sucks and conveys the plate material by a suction pad. It is also possible to place the plate product on a shelf in the retracted position, store the shelf in the storage position, and pull out the shelf in another storage position to the retracted position.
In this configuration, the shelf at the storage position is pulled out to the retracted position by the unloader, the plate material product is placed on the shelf at the retracted position, and the shelf on which the plate material product is placed is stored at the storage position. Since the unloader performs an operation of placing the plate material product above the pulled-out shelf, a space for the unloader to move up and down is secured above the unloader. Therefore, it is not necessary to secure an extra space above the shelf storage position, and space can be saved in the height direction. Further, since the unloader places the plate product on the shelf at the retracted position, and subsequently stores the shelf and pulls the shelf at the other storage position to the retracted position, the shelf can be efficiently put in and out.

  The plate material storage system according to the present invention includes a plate material stocker capable of storing a plate material product, and an unloader that unloads the plate material product processed from the plate material processing machine and stores the plate material product in the plate material stocker.

The plate stocker 43 has a standing frame 51 erected on one end of a base 50, and a plurality of stages of shelves 52 are provided on the standing frame 51 so as to be freely raised. The shelf 52 of each stage has a horizontal position and a retracted position, which are the use positions, by supporting both sides of the base end with a pair of left and right support pieces 53 protruding laterally from the standing frame 51 by a hinge 52a. It is possible to rotate between the inclined position where it jumps up.
As shown in FIG. 5, the support piece 53 is provided with a horizontal stopper 53a for receiving and holding the shelf 52 in a horizontal position and an inclination stopper 53b for receiving and holding the shelf 52 in an inclined position.

Further, the positions close to the hinges 52a on both sides of each shelf 52 and the intermediate position of the support piece 53 corresponding to each shelf 52 are connected by a shelf position restricting means 54 made of, for example, a tension coil spring. The shelf position restricting means 54 is a means for restricting the shelf 52 at two positions, that is, a horizontal position that is a use position and a retreated position that is flipped up.
As shown in FIG. 5A, the center line of the tension coil spring 54 is located above the rotation center of the hinge 52a in a state where the shelf 52 is received by the inclined stopper 53b and is bounced up. ), The shelf 52 is positioned below the center of rotation of the hinge 52a in the use position received by the horizontal stopper 53a. Accordingly, when the shelf 52 jumps up until the center line of the tension coil spring 54 moves upward from the center of the hinge 52a, the tension force of the tension coil spring 54 presses the shelf 52 against the inclined stopper 53b, and the tension coil spring 54 When the shelf 52 rotates to the horizontal posture side until the center line moves below the center of the hinge 52a, the pulling force of the tension coil spring 54 presses the shelf 52 against the horizontal stopper 53b.

This plate stocker 43 is provided with a plurality of shelves 52 provided in multiple stages in a storage box 60 so that they can be pulled out horizontally. That is, the position of each shelf 52 can be switched between a storage position in the storage box 60 which is a use position and a retracted position pulled out from the storage position. The shelves 52 of each step can be pulled out by being sandwiched between upper and lower guide rails 61a and 61b provided on both inner side walls of the storage box 60, and a part of the shelf 52 can be guided by the upper and lower guides even in the retracted position. It is held in a horizontal posture by being sandwiched between the rails 61a and 61b.

  FIG. 7 shows the loading operation of the plate product M by the unloader 42 onto the shelf 52 of the plate stocker 43. In the case of this plate stocker 43, as shown in FIG. 7A, one of the shelves 52 in the storage box 60 is sucked by the suction pad 35 of the gripping means 28 of the unloader 42 and pulled out to the retracted position. Thereafter, the unloader 42 carries out the plate material product M having the protruding molding portion Ma from the plate material processing machine 1 and places it on the shelf 52 in the retracted position as shown in FIG. Next, the unloader 42 sucks a part of the shelf 52 with the suction pad 35 and pushes it into the storage box 60. As a result, the shelf 52 on which the plate product M is placed is stored in the storage position.

Thus, also when this plate material stocker 43 is used, the plate material products M are placed on the shelves 52 of each stage, so that the plate material products M are not in direct contact with each other and are not damaged or crushed. Moreover, the plate material product M is not inclined and collapsed by stacking.
Further, the shelf 52 in the storage position is pulled out to the retracted position by the unloader 42, the plate material product M is placed on the shelf 52 in the retracted position, and the shelf 52 on which the plate material product M is placed is stored in the storage position. A space in which the unloader 42 moves up and down in order to place the plate product M above can be secured. Therefore, it is not necessary to secure an extra space above the shelf storage position, and space can be saved in the vertical direction. In the case of this plate stocker 43, the selection order of the shelf 52 on which the plate product M is placed is not limited, and the shelf 52 can be freely selected.
