I do. In the vicinity of the punch position P of the fixed table 22a, the intake port of the work shooter 30 is opened and closed freely, and a small product product obtained by cutting the material work W by punching is discharged from the work shooter 30. To be done.

[0004]

[Problems to be solved by the device]

 However, if the intake port of the work shooter 30 is arranged in front of the punch position P as described above, the intake port cannot be made too large due to the structural limitation of the work table 22. Therefore, in many cases, the size of the cut work piece is too large to be discharged from the inlet, and in that case, another discharge method is adopted. For example, when a large number of product workpieces are to be taken from the material work W, as shown in FIG. 4, a micro joint portion a called a micro joint is left between the material work W and the product work W1, and the entire material work W is worked. The work is carried out from the table 22, and the work of separating the minute joint portion a is performed at a place different from the punch press. Therefore, the number of separation steps increases, which is time-consuming, and the micro-joint a may break during the unloading of the workpiece W, which may hinder the unloading.

An object of the present invention is to provide a work discharge device of a turret punch press capable of discharging a large number of large-sized works that are taken out without using a micro joint.

[0006]

[Means for Solving the Problems]

 The work discharging device of the present invention is applied to a turret punch press having a work table extending in front of and on both sides of a punch position of a turret, and having a work feeding device in front of the punch position. In the turret punch press having the above structure, one side of the turret of the above table is a movable table that can be moved laterally, and the work discharge port is provided below the stationary position of this movable table.

 An embodiment of this invention will be described with reference to FIGS. The turret punch press 1 shown in FIG. 1 has a pair of upper and lower turrets 3a and 3b installed on a frame 4 having a C-shaped side surface, and a punch drive mechanism (not shown) for vertically moving a ram 14 on the upper frame portion. ) Is installed. A work table 5 is arranged in front of the turrets 3a and 3b.

As shown in the plan view of FIG. 2, the work table 5 is composed of a center table 5 a and side tables 5 b and 5 c located on the left and right sides of the center table 5 a. It is a movable table that moves in the axial direction). The center table 5a and the other side table 5c are fixed in position. The stationary position of the movable side table 5b is a position adjacent to the center table 5a, and below the stationary position is a work discharge box for discharging a large work of a large size among the product works cut by punching. 7 is installed. The entire upper surface of the work discharge box 7 is opened as a discharge port 7a. Further, a shooter opening 8a for discharging a product work having a relatively small size is provided at a portion near the punch position P of the center table 5a so as to be openable and closable. A work shooter 8 for discharging is installed below the center table 5a. The lid member that closes the shooter opening 8a is, for example, a vertically rotatable plate material that forms a part of the center table 5a in a horizontally closed state and a part of the shooter 8 in an opened state in which it descends and inclines. I shall.

In front of the punch position P, a carriage 10 that moves in the front-rear direction (Y-axis direction) on the rail 9 of the bed 2 is provided, and the carriage 10 is movable in the left-right direction (X-axis direction). A cross slide 11 is mounted. A work holder 12 is attached to the cross slide 11 for holding the end of the material work W on the work table 5. By moving the carriage 10 and the cross slide 11, the material work W on the work table 5 is fed back and forth and left and right. The carriage 10 and the cross slide 11 are driven by a feed screw and a servo motor, respectively. The center table 5a is provided with a groove (not shown) for moving a ball nut that is screwed into a feed screw for driving the carriage and extends in the front-rear direction (Y-axis direction). The rails 9 are provided on both side edges of the center table 5a so as to be located below the upper surface of the table.

The discharging / feeding device 13 is a device that sucks a large workpiece near the punch position P and feeds it to above the discharging port 7a of the workpiece discharging box 7, and is installed on the outer peripheral portion of the upper turret 3a. The discharging / feeding device 13 has a suction part composed of an electromagnet or a vacuum suction pad, and moves from near the punch position P to above the discharging port 7a of the work discharging box 7 by the indexing rotation of the upper turret 3a.
