Description

[Detailed explanation of the invention] This invention is a part of a continuous form processing machine that divides continuous forms into single forms after printing and disassembles continuous form sets into parts. The present invention relates to a chamber, particularly to an improvement of a storage chamber having a slit scrap winding shaft, and particularly to a holding plate for increasing the density of wound slit scrap.

During processing on a continuous form processing machine, before the fed paper is subjected to the above-mentioned division, disassembly, etc. processing, a 1.27 cm
It is common practice to cut off the perforation hole having the above width with a disk-shaped knife called a slitter and remove it from the continuous form. The slit waste, which has been removed with static electricity if necessary and cut off with a slitter, has a width of 1.27 mm.
The paper becomes a continuous strip of paper from 2.54 cm to 2.54 cm, and falls into the slit waste storage chamber provided at the bottom of the continuous form processing machine due to its own weight, and is discarded at an appropriate time. As continuous form processing machines have become faster in recent years, the number of times they have to be discarded has increased, and reducing this time and effort has become an important issue. In printing factories, etc., the slit waste on both sides of the paper roll is sucked in by a blower and sent to a waste paper collection site through a duct, but this method is noisy, so it is not used in offices like continuous form processing machines. It is unsuitable for machines that As another method, attempts have been made to make the slit waste compact by cutting it into appropriate lengths with a cutter, but this causes problems such as cutter noise and paper dust. A simpler solution exists in the ``paper wrapper'' disclosed in US Pat. No. 3,857,557, in which the slit waste is wound around a winding shaft shaped like a fork.

This invention relates to the improvement of the slit waste processing device using the above-mentioned winding shaft, and the slit waste overflows from the storage chamber during winding in the storage chamber, causing damage to the slitting mechanism and processing mechanism of continuous form processing machines. By installing a restraining plate on the top of the winding shaft to prevent the slit waste from becoming entangled in the processing, and by winding up the slit waste on the winding shaft at a high density, the capacity of the slit waste storage chamber can be effectively reduced. Increase above;
This reduces the number of times slit waste is discarded, and will be explained in detail below with reference to examples.

The continuous form slitting waste winding device of this invention, as shown in FIG. A plurality of rod-shaped winding arms 2, 2 are attached to the rotating disk 1' so as to draw a circular trajectory around the center of the rotating shaft 1, and the winding arms 2, 2 are swingable at the upper right side of the winding arms 2, 2. It consists of a restraining plate 4 attached to.

A rotating disk 1' having a plurality of winding arms 2, 2 is configured to rotate in the direction of arrow A (counterclockwise) inside the slit waste storage chamber 3 of the continuous form processing machine M. The restraining plate 4 has its own weight and/or
It is attached to be able to swing due to the stress of a spring S, and the lower limit of the swinging range is determined by the stopper 6. The structure is such that a gap B exists between the two.

Further, as shown in FIG. 2, the detector 9 is installed at a position where the rear end 8 of the retainer plate 4 pushes the lever 10 of the detector 9 when the retainer plate 4 is pushed upward.
The detector 9 is configured to issue a signal to stop the transfer of continuous forms in order to remove the slit waste 14, and a locking member L for fixing the holding plate 4 upward is provided. Further, inside the slit waste storage chamber 3, there is provided a slit waste box 11 placed on a trolley. On the surface of the plate 1' side, there is a winding arm 2,
The opening 15 has an opening 15 which is larger than the rotational circumference of the winding arm 2 and into which a plurality of winding arms 2, 2 can be inserted.

In the above description, the tip of the restraining plate 4 should normally be located in the vicinity of the rotational circumference of the winding arms 2, 2, but it may vary depending on the processing speed of the continuous form F over a wide range, the paper quality of the continuous form F, etc. In order to accommodate this, it is better to position the winding arms 2, 2 on the right side of the center of the rotating shaft 1, near the rotating circumference of the winding arms 2, so that winding safety is higher. It varies depending on the size of the rotational circumference of handle arms 2 and 2, but from 4 rotations per minute.
It is sufficient to design for 12 rotations, and it is better to design for 20 rotations or less at most.

Also, in the figure, the opening 15 of the slit waste box 11 is
is larger than the rotating disk 1', but it only needs to be large enough to allow the winding arms 2, 2 to be inserted and rotated. It may also be more removable.

In addition, in this invention, the structure and mounting position of the shaft 5 that allows the holding plate 4 to swing are not limited to those shown in the drawings. means a filled out or printed sheet.

Next, the operation and effect of this invention will be explained in accordance with the use of the above-mentioned continuous form slit waste winding device.

In FIG. 1, the continuous form F sent by the tractor 12 of the continuous form processing machine M has its feed hole portion cut off by the slitter 13, and this feed hole portion becomes a band-shaped slit waste 14 and is slitted. It falls into the waste storage room 3. The paper thickness of the continuous form F is normal, that is, about 50 grams per square meter, and the speed at which it is fed by the tractor 12 is about 50 grams per minute.
If the distance is less than 80 meters, the slit waste 14 will first accumulate at the bottom C of the slit waste storage chamber 3, then be scooped up by the winding arms 2, 2, and wrapped around the winding arms 2, 2. If the paper thickness of continuous form F is too thick,
and/or if it is sent at high speed,
It falls directly near the winding arms 2, 2, and the winding arms 2,
2 and winds around the winding arms 2 and 2. The wrapped slit waste 14 is squeezed by the holding plate 4 as it passes through the gap B between the winding arms 2, 2 and the lower surface of the holding plate 4 as the rotating shaft 1 rotates. 2, it is wound with high density without sagging.
The wrapped slit waste 14 is first collected by the winding arm 2,
It forms a column or other shape with an oval cross section with two centers at 2, but as the layers are piled up, the shape becomes closer to a cylinder. This means that the tip of the holding plate 4 at the lower limit of its swinging range about the shaft 5 is determined by the stopper 6, and the width of the gap B in the vertical direction is secured with respect to the rotational circumference of the winding arm. Depends on the configuration. As the diameter of the slit waste 14 wound up into a cylindrical shape becomes slightly larger, the circumferential speed increases, so the slit waste 14 accumulated at the bottom C of the slit waste storage chamber 3 is rolled up and moved to the right in the figure, so that the slit waste 13 A space on the left side from which the slit waste 14 falls is secured. When the wound slit waste 14 reaches a sufficient size, the holding plate 4 rises and the rear end 8 of the holding plate 4 descends, and the lever 10 of the detector 9
As a result of pressing , a signal indicating that the slit waste storage chamber 3 is full is issued, and the continuous form processing machine M is stopped. After that, if the holding plate 44 is fixed with the locking member L and the slit waste box 11 is pulled out together with the cart, the slit waste 14 wound up inside the slit waste box 11 will be larger than the opening 15 of the slit waste box 11, and Since the slit waste 14 is simply wrapped around the winding arms 2, 2 in the same way as spaghetti is wrapped around a fork, the wound slit waste 14 falls into the slit waste box 11 and is stored in the slit waste storage chamber. It can be taken out together with the slit waste 14 remaining at the bottom C of 3.

As described above, the continuous form slit waste winding device according to this invention reliably introduces the slit waste 14 into the slit waste storage chamber 3 over the entire feed speed range of the continuous form F using the winding arms 2, 2, and slits the continuous form F. The waste 14 naturally wraps around the winding arms 2, 2 in the storage chamber 3, and the suppressing plate 4 located at the upper part prevents the waste from overflowing from the storage chamber 3 during winding. The continuous form processing machine M can be operated safely and reliably without getting entangled with the processing mechanism, and the slit waste 14 can be wound up with high density by the holding plate 4 to substantially expand the capacity of the slit waste storage chamber 3 to remove and dispose of the slit waste. This reduces the number of times and saves labor, and when removing the slit waste 14, a moving vehicle is provided at the bottom of the slit waste box 11, so it can be easily pulled out from the continuous form processing machine M, and the slit waste can be easily transported to the disposal site. It is mobile and highly maneuverable.
Since the waste of volume and time in the entire process from storing to discarding the slit waste 14 is eliminated, the efficiency and reliability of the continuous form processing machine M are significantly increased. Therefore, this invention is a very useful invention industrially.
