Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a punching device for punching a tape-shaped or card-shaped sheet.

[Prior Art] A required punching device is used for punching to record the frequency of use, such as a paper tape reader / punch used for recording / reproducing information or a telephone card or an orange card. The perforated scraps are received in a storage box provided in the perforation device, and can be collectively discharged as needed.

[Problems to be solved by the invention] However, since the perforated scraps are piled up in a mountain shape in the storage box, even if the perforated scraps have a relatively small volume compared to the internal volume of the storage box, the perforated scraps can reach the vicinity of the discharge port of the punching mechanism of the punching device. Drilling scraps will be prominent, and the discharge of newly generated drill scraps can be prevented. This leads to piercing mistakes and causes an error in the subsequent reading. Particularly in recent years, since the punching device has been downsized and the storage box is not provided with a sufficient volume, for example, in the paper tape reader / punch, the discharge port of the punching mechanism is used before the punching of one roll of paper tape is completed. There is a risk that perforated scraps will be accumulated until it reaches the point, and the outlet will be clogged.

Therefore, the present invention has been made in view of the above-mentioned problems, and the perforated scraps accumulated in the storage box are always scattered to store the perforated scraps by fully utilizing the internal volume, and the discharge port of the punching mechanism. An object of the present invention is to provide a punching device capable of avoiding clogging in the machine.

[Means for Solving the Problems] In order to achieve the above object, the punching device according to the present invention punches a tape-shaped or card-shaped sheet 5 by punching and receives a punching scrap 7 in a storage box 8. In the punching device, the weight is provided inside the storage box, one end of which is fixed to a part of the storage box, and the other end of which is positioned immediately below the discharge port 6a of the perforated scrap and the weights 11, 12 are provided. Is provided with elastic members 10 and 13, wherein the elastic member scatters the perforated scraps into the storage box by the weight being actuated by vibration applied to the storage box by a punching operation. I am trying.

[Operation] When the sheet 5 is punched, the vibration at that time is transmitted to the elastic member provided in the accommodation box, and the vibration of the weight arranged in this elastic member is magnified. Then, the perforated scraps are blown off by the vibrating weight when discharged from the discharge port. As a result, since the perforated scraps are always almost uniformly diffused in the storage box 8, a pile-shaped accumulation state does not occur, and a sufficient amount corresponding to the volume in the storage box 8 can be stored and the punching mechanism can be removed. It is possible to prevent mistakes in drilling without clogging the outlet. Therefore, it is extremely practical when continuous punching is performed like a paper tape reader / punch punching device.

[Embodiment] An embodiment of the present invention will be specifically described below with reference to the drawings. In the embodiment shown in FIGS. 1 and 2, a paper tape reader / punch device is shown as the punching device.

Here, two paper tape reel mounting units 1 and 2 are arranged side by side. The perforated tape 3 mounted on one of the paper tape reel mounting portions 1 is adapted to be pulled out through the leader head 4, and information is read in the perforated state of the perforated tape 3. Further, the paper tape 5 mounted on the other paper tape reel mounting portion 2 is adapted to be pulled out through the punching mechanism 6, and when passing through the punching mechanism 6, the position corresponding to the information at the same time when the feed wheel is punched. Is drilled. Usually, the field wheel has a direct diameter of about 1 mm, the information hole has a diameter of about 1.8 mm, and the drilling speed is about 50 characters / sec. The punching scraps 7 generated at this time are detachably attached to one side surface of the punching device through the discharge port 6a of the punching mechanism 6 and a storage box 8 is attached.
Can be received within.

Since the storage box 8 has the discharge port 6a located above the center of the inside,
When it is inserted into the accommodation box mounting portion 9 of the punching device, it has a notch 8a for avoiding the discharge port 6a and a coil spring 10 standing upright at the center of the bottom.
A scattering plate 11 also serving as a weight is attached to the top of the. When the storage box 8 is mounted on the storage box mounting portion 9, the scattering plate 11
Is located immediately below the discharge port 6a.

The spring constant of the coil spring 10 and the weight of the scattering plate 11 are set in accordance with the frequency of resonance with the mechanical vibration transmitted to the storage box 8 when the punching mechanism 6 operates, for example, 50 Hz.

With such a structure, when the punching scraps 7 generated during the punching process fall into the storage box 8, the coil spring 10
The perforated scraps 7 are almost evenly diffused in the storage box 8 by the movement of the scattering means constituted by the scatter plate 11 and the scattering plate 11. Therefore, the perforated scraps in the conventional storage box 8'as shown in FIG. Instead of depositing in a mountain shape like No. 7, it is deposited on an average as seen in FIG. That is, the perforated scraps 7 rise up to reach the discharge port 6a, and the discharge port is not clogged, and the perforated scraps 7 can be sufficiently stored in the storage box 8.

It should be noted that the storage box 8 is preferably made of transparent plastic so that the degree of accumulation of the punched scraps 7 inside can be observed from the outside.

By the way, in another embodiment shown in FIG. 4, the above-mentioned scattering means is composed of a leaf spring 13 having a weight 12 attached to the tip thereof, which protrudes from the inner wall of the housing box 8 to the inner center thereof, and the discharge port 6a.
It is located directly below. Other configurations are substantially the same as those in the above-mentioned embodiment.

The scattering means does not necessarily need to use a spring,
For example, any structure may be used as long as it has a function of operating in the housing box 8 by the vibration obtained by the punching operation and diffusing the perforated scraps evenly, such as a pendulum structure.

It is most effective when the above-mentioned operation is a resonance with the vibration obtained by the punching operation.

Further, in the above-described embodiment, the punching device of the present invention is applied to punching a paper tape, but the punching object is not limited to a tape-shaped sheet, and a card-shaped card such as a telephone card or an orange card. Needless to say, the device of the present invention can be applied to perforations for recording the frequency of use, as well as other sheets.

[Advantages of the Invention] As described above, according to the punching device of the present invention, one end is fixed to a part of the storage box, and the weight is fixed to the other end located immediately below the discharge port of the perforated scraps. Since an elastic member is installed inside the storage box and the vibration of the weight located immediately below the discharge port is magnified during the punching operation, the punched scraps that have already accumulated in the storage box are piled up in a mountain shape. ,
The perforated scraps can be blown off at the stage of being discharged from the discharge port and can be accumulated in the storage box on average. Therefore, it is possible to sufficiently store the perforated scraps in the storage box without the rise of the perforated scraps reaching the discharge port of the punching mechanism and causing clogging as in the conventional case. Further, it is highly useful especially when continuous perforation is performed like a paper tape reader / punch.
