Abstract

(57) [Summary] [Purpose] It is possible to automatically transfer the scraps generated in the stripper of the punching machine to the disposal site. [Structure] A belt conveyor 2 that circulates and moves in a substantially horizontal direction, and a horizontally long suction port 3a corresponding to the width of the belt conveyor 2 are arranged so as to face the downstream end of the belt conveyor 2. The debris discharging device 1 is constituted by the suction unit 3 and the suction duct 4 which is detachably connected to the suction unit 3 and has a length reaching the disposal site. The debris generated in the stripper section falls on the belt conveyor 2 and is conveyed to the downstream side, where it is sucked into the suction port 3a of the suction section 3 and passes through the suction duct 4 to a disposal site such as an incinerator. Transferred automatically.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a scrap discharging device used integrally with a punching machine.

[0002]

[Prior Art]

 Generally, a punching machine is used to form a blank plate such as a folding carton. In such a punching machine, while the sheet is moved intermittently, first, the punching section forms a scoring groove or a folding ruled line by a die, and then the stripper section forms an upper pedestal and a lower pedestal. After the scraps are removed from the sheets by the punches attached to the bases, respectively, the punched sheets are collected. Then, the scraps generated in the stripper section are stored in the trash box located below the pedestal.

[0003]

[Problems to be solved by the device]

 As described above, conventionally, the scraps generated in the stripper are stored in the trash box, so the scraps must be replaced before the trash box is full, and the scraps have accumulated. It was a very troublesome task because I had to carry the trash to the disposal site.

Therefore, in order to deal with such a problem, using the trash box, a slanted shaving tray is installed inside the trash box, a suction port is provided on the lower side of the shaving tray, and a suction fan is used to draw the dust through a suction duct. A device that conveys the waste to the disposal site was considered, but in this case, if the suction port is small, a blind spot will be created and the scrap will be accumulated there, and if it is large, a very large capacity fan will be needed to suck. It was. In addition, there is a problem that the block of scraps that could not be completely sucked and remained on the pedestal often fell into the suction port at one time due to machine vibration etc. and the suction port was clogged. Was not.

The present invention has been made in view of the above circumstances, and an object thereof is to automatically collect debris generated in the stripper part to a disposal site with a fan having a relatively small capacity. An object of the present invention is to provide a scrap transport device for a punching machine that can reliably transport the waste.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the scrap discharging apparatus of the present invention has a belt conveyor that circulates and moves in a substantially horizontal direction, and a horizontally long suction port corresponding to the width of the belt conveyor has a downstream end of the belt conveyor. And a suction duct removably connected to the suction unit and extending to the disposal site.

[0007]

[Action]

 The debris discharging device of the present invention described above is used by being installed below the stripper part of the punching machine. Then, the debris generated in the stripper unit is dropped on the belt conveyor and conveyed to the downstream side of the belt conveyor, then sucked into the suction port of the suction unit and transferred to the disposal site through the suction duct.

[0008]

【Example】

 FIG. 1 is a perspective view showing a scrap discharging apparatus as an embodiment of the present invention. As shown in FIG. 1, the scrap discharging apparatus 1 includes a belt conveyor 2, a suction unit 3, and a suction duct 4. The belt conveyor 2 is mounted on a movable base 5 so as to circulate in a substantially horizontal direction. The suction part 3 is arranged on the downstream side of the belt conveyor 2 in a state where a horizontally long suction port 3 a provided at the fan-shaped tip of the suction part 3 faces the downstream end of the belt conveyor 2. The suction duct 4 has one end connected to the rear end of the suction unit 3 and has a length to reach a disposal site (not shown) such as an incinerator.

The connecting portion between the suction portion 3 and the suction duct 4 can be removed so that the apparatus can be easily moved and stored when it is not needed.

As shown in FIG. 2, the above-mentioned scrap discharge device 1 is installed and used below the stripper portion 7 of the punching machine 6. In this case, because of the space, the moving direction of the belt conveyor 2 is set to be at a right angle to or close to the flow direction of the sheet S of the punching machine 6. Then, the other end of the suction duct 4 is directly connected to the incinerator.

In this punching machine 6, first, the printed sheet S is intermittently conveyed from the paper feeding section 8 to the punching section 9, where it is cut or folded by the punching dies 9a and 9b. The ruled line of is formed. Then, the scraps are intermittently sent to the stripper unit 7, where the scraps are removed by the pulling rods attached to the upper pedestal 7a and the lower pedestal 7b, respectively. It falls on the belt conveyor 2 of the waste discharging device 1. The fallen scraps are conveyed to the end portion by the belt conveyor 2, where they are sucked by the suction port 3 and transferred to the disposal site through the suction duct 4. On the other hand, the punched sheets S are sequentially stacked on the pallet of the stacking unit 10.

[0012] In some cases, the debris falling from the stripper unit 7 may fall onto the floor from both sides of the belt conveyor 2, but in order to prevent this, the width of the belt conveyor 2 should be increased. Alternatively, guides with a little height may be provided on both sides of the belt conveyor 2.

[0013]

[Effect of the device]

 As described above, in the scrap discharging apparatus of the present invention, the scrap is dropped on the belt conveyor for transport, sucked by the suction unit, and directly transported to the disposal site by the suction duct. Since the scraps are automatically conveyed to the disposal site with a relatively small capacity fan without being clogged, it is not necessary to replace the waste bins one by one as in the past, and the punching process can be performed efficiently. ..
