[0002]

2. Description of the Related Art Chippings generated during processing by a turret punch press are discharged to the outside of a frame through a space between disk supports arranged below a die of a lower turret, but remain inside the die. Since the scum falls in an irregular state when the turret rotates, the scum is often scattered and accumulated on the upper surface and the periphery of the lower frame located below the lower turret. It is necessary to open the turret cover and perform cleaning work such as scraping out scraps using a special tool for cleaning. Also, cables such as LS are arranged in the area to be cleaned. There is a problem that there are inconvenient factors for safety management, such as a cause of failure of the vehicle.

[0003] The present invention has been made in view of the above-mentioned circumstances, and enables scraps such as scraps to be automatically and automatically eliminated during a machining operation. An object of the present invention is to provide a scrap discharging device that can eliminate a failure factor.

A scrap feeder configured to vibrate the trough in the transport direction so that scrap such as the scraps in the trough can be discharged to the outside of the machine.

(2) The trough has a linear and elongated shape, and a plurality of vibration generators are provided below the lower turret so that scraps such as scraps can be carried out of the machine. (1)
The scrap discharging device as described in the above.

(3) The trough is formed in an arc shape, and is engaged with a position where a die of the lower turret is provided, and a trough such as a scrap is formed below the die and below the outer peripheral edge of the lower turret. The scrap discharging apparatus according to the above (1), wherein a plurality of vibration generators are provided so that the scraps can be carried out of the machine, and a plurality of the vibration generators are combined and connected at desired positions to form an annular shape as a whole.

(4) The trough has a shape of a cylindrical housing having an open top and its size is engaged with a lower turret.
The lower turret has a hollow structure in which only a central portion that engages with the rotation shaft is provided. The hollow structure is provided so as to be engaged with a lower side of the lower turret, and at least one of the scraps such as scraps can be carried out of the machine. The scrap discharging device according to the above (1), wherein the scrap discharging device is configured to include at least a plurality of vibration generators.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below.

FIG. 1A is a side view showing a main part of a scrap discharging apparatus according to the present invention, FIG. 1B is a perspective view showing an example of a vibration feeder, and FIG. 2 is a plan view showing an example of arrangement of a vibration feeder. FIG. 3 is a perspective view showing an example of the arrangement of the vibrating feeder, FIG. 4 is a perspective view showing an example of an arcuate trough, and FIG. 5 is a perspective view showing an example of a hollow cylindrical open trough.

Referring to the drawings, 1 is a trough (trough), 2 is a vibration generator of an ultrasonic type, an electromagnetic type, a vibration motor type or the like, and the vibration generator 2 and the trough 1 use a vibration feeder Fv. While receiving scraps such as scraps generated during processing by the turret punch press P and falling into the trough (gutter) 1, the vibration generator 2 of the ultrasonic type, the electromagnetic type, the vibration motor type, etc. The vibrating feeder can function as a linear vibrating feeder by vibrating in the unloading direction.

FIGS. 2 and 3 show a linear elongated trough 1.
Shows the configuration of an embodiment in which a plurality of vibration feeders YL, YF, and XF each having a combination are disposed, and scraps such as scraps conveyed by the vibration feeders YL and YF are collected by the vibration feeder XF and collected outside the unloader. Box 4
To accumulate.

The operation will be described based on the above configuration.

A vibration feeder YL previously disposed between the lower turret and the lower frame of the turret punch press P,
The trough (gutter) 1 receives scraps, such as scraps, which are generated at the time of machining and fall by the YF, and vibrates in the unloading direction of the vibration generator 2 such as an ultrasonic type, an electromagnetic type, and a vibration motor type. The scrap is conveyed into the trough 1 of the vibration feeder XF by the action, and the conveyed scrap such as scrap is
For example, in this embodiment, the sheet is discharged and accumulated in the accumulation box 4 by the unloading action of the vibrating feeder XF as the final assembly feeder.

In another embodiment, an arc-shaped trough as shown in FIG. 4 is arranged in engagement with the lower turret, and a plurality of such troughs are connected so as to be connected to each other. They are collected in one place, and scraps such as scraps are collected in a collecting box.

Further, as shown in FIG. 5, the shape of the upper turret is a hollow cylindrical body, and only the center portion of the lower turret that engages with the rotation shaft of the lower turret is hollowed out. At least one or more vibration generators are provided so that scraps such as scraps can be carried out of the machine, and a trough (gutter) is provided to an accumulation box located below a discharge port appropriately disposed at a desired location. 1) The scraps such as the scraps in 1 are accumulated. In addition, when the trough is formed by the upper open cylindrical hollow casing, the flow is appropriately regulated in order to efficiently guide and discharge scraps such as scraps to the discharge port, and the scrap is discharged to the discharge port. A baffle plate may be provided so as to gather.

[0017]

According to the present invention, it is possible to automatically and automatically remove scraps such as scraps during the machining operation, eliminating the need for an operator to remove scraps and eliminating the cause of machine failure. Present.
