Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a thin plate punching device used in manufacturing products such as floppy disks.

``Prior art'' For example, when manufacturing floppy disks, the film material is intermittently fed by a feed device and the product is punched out by a press device. Conventionally, one feed device is installed before or after the press device. Fig. 3 shows an example where the feed device 2 is placed before the press device 1, and Fig. 4 shows an example where the feed device 2 is placed after the press device 1. It shows.

[Problems to be Solved by the Invention] However, when a thin sheet material is conveyed by one feed device for a press device as in the past, there is a problem that the sheet material meanderes or waves.

[Means for Solving the Problems] In order to solve the above problems, the present invention arranges feed devices at the front stage and the rear stage of the press device, and synchronizes the feed speeds of both feed devices. It is a feature.

[Function] Since the feed devices before and after the press device feed the thin plate in synchronization, the thin plate is accurately guided and passes through the press device even during intermittent feeding.

[Embodiment] Hereinafter, an embodiment in which the present invention is applied to a floppy disk manufacturing line will be described with reference to FIGS. 1 and 2.

First, an overview of the entire floppy disk manufacturing line will be explained based on FIG. 2. 10 in the figure is a press device, which presses the polyester Fisilem material W to the Fronby disk F.
It punches out. Feeding devices 11 and 12 are provided before and after the press device 10, respectively, so that the material W can be fed intermittently to the press device 10.

The concept of the structure of this part is explained based on Figure 1.
The press device 10 includes upper and lower molds 13 and 14, and performs a punching operation at regular intervals. Feed device 11
S12 is to intermittently feed the material W in the direction of the arrow in accordance with the operation timing of the press device 10, and the material W is forcibly conveyed by sandwiching the material W between upper and lower rollers (not shown). ing. Both feed devices 1 in this case
1.12 operation timing and feed speed are belt 15
The two are contacted and synchronized.

In addition, the floppy disk F formed by the press machine 10 is separated from the remaining film Wa by a separating device 16 installed immediately after the press machine 10, as shown in FIG. Conveyor 1 below it
7, and while being conveyed by this conveyor 17, the punched dregs from the center hole are separated. Then, the floppy disks F are conveyed to the accumulating device 19 for the pin container 18, and are sequentially stacked on the pin container 18 in a predetermined number so that the pins of the pin container 18 enter the center hole. It is designed to be carried out together with 18 by a carrying out device 20.

Note that 21 is an uncoiler for unwinding the film material W wound into a coil, 22 is an accumulator for stably feeding the film material W, and 23 is a line for winding the remaining film Wa.

Next, the effect will be explained.

Intermittent conveyance of the material W to the press device IO is performed by feed devices 11 and 12. In this case, two feed devices 11, 1 placed before and after the press device IO
Since the material W is moved in step 2, the material W passes through the press device 10 while being accurately guided, and the material W does not meander during its passage.

In addition, since the feed devices 11 and 12 feed the material W synchronously with the timing of the press device IO,
The material W does not wave or wave even though it is intermittently conveyed. Therefore, accurate processing can be performed while ensuring stable conveyance.

[Effects of the Invention] As explained above, according to the present invention, since the thin plate is guided by the feeding device before and after the press device, there is no meandering of the thin plate. In addition, since the foot devices synchronously feed the material before and after the press device, the thin sheet does not wave. Therefore, it is possible to process the thin plate while stably conveying it.
