Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a die housing device for housing a punch die and a die die which are supplied to an upper turret or a lower turret of a turret punch press.

[0002]

2. Description of the Related Art A punch press for punching a plate material such as a sheet metal must have a large number of punch dies and die dies according to the shape of the holes. In the turret punch press, these many punch dies and die dies are housed in upper and lower turrets rotatably provided on a machine frame. Then, by rotating the turret, any one set of punch dies and die dies is selectively supplied to a predetermined processing position from the large number of punch dies and die dies.

Further, when exchanging the punch die and die die attached to the upper and lower turrets with another die, a desired die is selected from the punch die and die die accommodated in the die accommodating device. Select the die, remove the punch die and die die attached to the upper and lower turret by the operator or die exchanging device, and move the punch die and die die stored in the die storage device up and down. Attach it to the turret.

In order to manage these many punch dies and die dies, a technique has been proposed in which an identification medium is attached to the punch dies and die dies and the identification medium is detected by a detection device. For example, JP-A-63-
Japanese Patent No. 174733 proposes a technique in which a bar code indicating the dimensions and shapes of the punch die and the die die is attached to the head of the punch die, and the bar code is read by a sensor provided above the turret. There is. This allows
The punch die and die die on the turret can be easily specified.

Further, in a punch press provided with an automatic die changer, a punch die, a die die, and an identification medium at a die mounting position are attached, and the identification medium is attached to a die exchange arm of the die exchange apparatus. The punch die, the die die, and the die mounting position can be easily specified by reading with the identification medium reading device.

[0006]

However, in such a conventional technique, when the die is replaced by an operator and the die is wrongly attached to the upper and lower turrets, correct punching is performed. There is a problem that processing is not performed. Therefore, in the prior art, it is possible to confirm whether the correct mold is mounted by reading the information of the mounting mold with a sensor provided above the turret, but mounting the mold on the turret of the punch press, An error can be finally detected at the time when the mold identification medium is detected by the detection device, and at that time, it is necessary to replace the mold with a correct mold again, which requires a lot of man-hours.

Further, in a punch press equipped with an automatic mold exchanging device, when a die stored in the die storing device is selected and mounted on the upper and lower turrets, the die exchanging arm of the die exchanging device is identified. You can recognize punch dies and die dies by the medium reading device, but the dies stored in the die storage device must be checked by the operator beforehand with the dies required by the operator and the station position. When the operator sets the wrong mold because it is set in the mold storage device, the error cannot be detected at that time, and the time when it is read by the identification medium reader of the mold exchange arm or The die can be mounted on the turret of the punch press, and the error can be detected only when the identification medium of the die is detected by the detection device. Work is required, it takes a number of steps still occur.

The object of the present invention was made by paying attention to the problems of the conventional techniques as described above, and a metal mold capable of identifying a station of a mold storage shelf or a punch metal mold or a die metal mold. An object of the present invention is to provide a mold storage device, and to enable management of held molds other than those stored in a turret of a punch press.

[0009]

In order to achieve the above-mentioned object, a mold storage device of the invention according to claim 1 has a mold storage rack for storing a plurality of punch dies or die dies,
The mold storage shelf is provided with a plurality of stations, and each station is provided with an identification medium for identifying each station.

Therefore, when the punch mold or the die mold is stored in the mold storage rack in the mold storage device, the identification medium provided in the mold storage rack in which the punch mold or the die mold is stored. The punching die or die die is read out and the identification medium provided on the die storage shelf is read to read out the punch die or die die, and the punch die or the punch die stored at a desired position is read. Make sure to take out the die mold.

According to a second aspect of the present invention, there is provided a die accommodating apparatus according to the first aspect, wherein the die accommodating shelf has a plurality of stations for accommodating a plurality of punch dies or die dies. A medium having a rotatable multi-stage disc shape, which is vertically movable for reading the identification medium provided in each station, and reciprocally movable in a direction intersecting the rotation direction of the mold storage rack. It has a reading device.

Therefore, while rotating the disk-shaped mold storage rack that stores the punch mold and the die mold, the medium reading device is moved in a direction intersecting with the rotation direction of the mold storage rack, The position of the mold is confirmed by reading the identification medium provided on the mold storage shelf.

According to a third aspect of the present invention, there is provided a die accommodating apparatus according to claim 1, wherein the die accommodating shelf includes a plurality of stations for accommodating a plurality of punch dies or die dies. It is a fixed shelf and has a reading device for reading the identification medium provided in each station.

Therefore, when the punch mold or the die mold is stored in the fixed mold storage shelf, the reading device is moved to be provided at the position where the mold is stored in the mold storage shelf. The identification medium is read, the position is confirmed, and mold management is performed. In addition, when the punch die or die die stored in the fixed die storage shelf is taken out, the reader is moved to read the identification medium provided at the die position to be taken out, and the position is read. To confirm.
