I have. In each of the passages 81 to 88, a plurality of small passages 26 communicating with the surface of the roll are formed in the depth direction of FIG. Side valves (not shown) for the lower blade port 22 are slidably disposed on both end surfaces of the lower blade roll 22. The side valve itself is attached to the main body of the apparatus, and does not rotate together with the lower blade roll 22, but is configured to be rotatable about an axis. A suction port 25 is formed on the sliding surface of the side valve with the lower blade roll 22. The position of the suction port 25 can be adjusted by rotating the side valve. In order to obtain smooth sliding of the side valve with the lower blade roll, it is preferable that at least the vicinity of the sliding surface with the lower blade roll be formed of resin. Each of the passages 81 to 88 is connected to a suction blower 76 via a suction port 25 of a side valve. That is, each of the passages 81 to 88 is sucked by the blower 76 when located inside the suction port 25, and is not suctioned when located outside the suction port 25. In addition, two passages 88, 87 are arranged before and after the one blade 24 of the lower blade roll in the paper transport direction in the vicinity of the blade 24, and the other blade 24 also has two passages. Passages 83, 84 are located in close proximity. This is because the paper is sucked and fixed to the square bar-shaped blade 24 when the paper is cut, so that the cutting can be performed reliably and easily. This is for separately sucking and controlling the tip of the downstream downstream paper. Further, the blade 23 of the upper blade roll and the blade 24 of the lower blade roll are arranged at positions where the surface of each roll is divided into two equal parts, and the blade of the upper blade roll is The distance on the mouth surface between the blades and the distance on the roll surface between the blades of the lower blade roll are designed to be the same as the length of one sheet of paper. The knife-shaped paper is cut into a sheet-shaped paper by the knife hole part 20.

The upper lathing portion 50 is a passage provided in the lower roll 22 of the knife roll portion 20 and the upper seal port 31 and the lower roll 22 of the seal roll portion 30. 8 and passages 91 to 102 provided in the upper seal roll 31. The lower blade roll 22 and the upper seal roll 31 are provided so as to contact each other in a substantially horizontal state. In the case of FIG. 5, the two passages 8 1, 8 2 located above the lower blade roll 22 are sucked, and the paper is brought into close contact with the lower blade roll. In addition, the passage 83, which is located on the right side of the drawing and in contact with the upper seal roll 31, is eventually switched from suction to non-suction, but as will be described later, the passage 84 is switched from non-suction to passage 83. Even after the switching, suction is performed for a while, that is, until it moves to a position outside the suction port 25. The lower two passages 85, 86 and the passages 87, 88 located on the left side are not suctioned. In the case shown in FIG. 5, the nipper is slightly separated from the guide roll 63 and is slightly sucked by the passage 81 of the lower blade roll 22 and adheres to the surface thereof. At the upper blade 21 and the lower blade roll 22. The cut sheet-shaped vapor is delivered to the upper seal port 31 near the contact portion with the upper seal roll 31, and thereafter, is sucked and transported by the upper seal roll 31.

The upper seal roll 31 has 12 passages 91 to 102 for suction, and each passage 91 to 102 communicates with both end surfaces of the upper seal roll 31. There. In each of the passages 91 to 102, a plurality of small passages 36 communicating with the surface of the roll are formed in the depth direction of FIG. The upper seal roll 31 is driven to rotate counterclockwise. Side valves (not shown) for the upper seal roll 31 are slidably disposed on both end surfaces of the upper seal roll 31. The side valve itself is attached to the main body of the apparatus, and does not rotate together with the upper seal roll 31, but is configured to be rotatable about an axis. A suction port 35 is formed on a sliding surface of the side valve with the upper seal roll 31. The position of the suction port 35 can be adjusted by rotating the side valve. This side valve is in contact with the upper seal roll. In order to obtain smooth sliding, it is desirable that at least the vicinity of the sliding surface with the upper seal roll is made of resin.

That is, each of the passages 91 to 102 is sucked by the blower 76 when positioned inside the suction port 35, and is not suctioned when positioned outside the suction port 35. In the case shown in Fig. 5, each passage is switched from non-suction to suction at a position slightly past the contact with the lower blade roll 22 by the side valve, and slightly before the contact with the retort roll 41. To switch from suction to non-suction.

FIG. 6 is a diagram for explaining the operation of the overlapping unit 50. FIG. 6 (a) is a view showing a state immediately after the sheet is cut by the upper blade roll 21 and the lower blade slot 22. In ①, the sheet-shaped paper located downstream is shown in ②. The positions indicated by ① and ② are the leading end of each sheet-shaped paper. The upstream sheet-shaped par has a slack portion la at the rear end. Hereinafter, the reason why the slack portion 1a occurs will be described. The rotation speed of the lower blade roll 22 and the upper seal roll 31 is the same, but the outer diameter of the lower blade roll 22 is slightly larger than the outer diameter of the upper seal roll 31. For this reason, the transport speed of the vapor by the lower blade roll 22 is slightly higher than the transport speed of the vapor by the upper seal roll 31. Due to the difference in the transport speed of the paper of the two mouths, a slack portion 1a is generated at the rear end of the sheet-like paper upstream. The slack 1a gradually increases with the transport of the vapor. FIGS. 6 (b) and 6 (c) are views showing a state where the slack portion 1a gradually increases with the rotation of the roll.

FIG. 6D is a view showing a state immediately before the downstream sheet-like paper is transferred from the lower blade roll 22 to the upper seal roll 31. That is, at the position where the roll slightly rotates from the state of FIG. 6 (d), the passage 83 provided on the downstream side of the square rod-shaped blade 24 of the lower blade roll 22 is switched from suction to non-suction. Then, the suction of the tip of the downstream sheet-like paper by the lower blade roll 22 is stopped. On the other hand, the passage 102 of the upper seal roll 31 is switched from non-suction to suction at a position where the roll slightly rotates from the state shown in FIG. 6D. As a result, the front end of the sheet-shaped paper on the downstream side is sucked by the upper seal roll 31, and thereafter, is transported in close contact with the surface of the upper seal roll 31. Ma In addition, the passage 84 provided on the upstream side of the square bar-shaped blade 24 of the lower blade roll 22 is held for a while even after the passage 83 is not suctioned, so that the upstream The rear end of the sheet-like sheet is transported for a while while being kept in close contact with the surface of the lower blade roll 22. FIG. 6 (e) is a diagram illustrating a state where the suction of the upstream sheet-shaped vapor by the lower blade roll 22 is stopped. As shown in FIG. 6 (e), when the blade 24 of the lower blade roll 22 moves to a position slightly away from the contact portion with the upper seal roll 31, the passage 84 switches from suction to non-suction. As a result, the rear end of the upstream sheet-shaped paper is free. When the lower blade roll 22 and the upper seal roll 31 further rotate in this state, the slack portion 1 a at the rear end of the upstream sheet-like base paper is sucked into the surface of the upper seal port 31. Is done. At this time, the tip of the downstream sheet-shaped paper has already been sucked under the rear end of the sheet-shaped paper on the upstream side, so as shown in Fig. 6 (f). In addition, the rear end of the upstream sheet-shaped paper is superimposed on the front end of the downstream sheet-shaped paper. That is, each sheet-shaped paper cut by the knife roll section 20 is placed on the leading end of the downstream sheet-shaped paper by the overlapping section 50 and the rear end of the upstream sheet-shaped paper. The parts are conveyed so that the parts overlap.

Also, as described above, 12 passages 91 to 102 are formed inside the upper seal roll 31, and each passage 91 to 102 has a plurality of passages communicating with the roll surface. A small passage 36 is formed. The lower seal roll 32 is provided with two male dies 34 and 34 corresponding to the female dies 33 of the upper seal roll 31. As shown in FIG. 6 (d), the leading end of the sheet-shaped paper cut by the knife mouth portion 20 covers the female die 33 of the upper seal roll 31 so as to cover the female die 33. Delivered to the seal roll 31. In addition, the rear end of the sheet-shaped paper is placed so as to overlap the front end of the downstream sheet-shaped paper that has been conveyed so as to cover the other female mold 33. Suction roll 31 Sent. The diameter and the rotation speed of the upper seal roll 31 and the lower seal roll 32 are the same.

FIG. 7 (a) is a diagram showing a state where sealing is performed by the seal roll portion 30. As shown in FIG. 7 (a), a portion where the rear end of the upstream sheet-shaped paper and the front end of the downstream sheet-shaped paper are overlapped (hereinafter, simply referred to as an overlapped portion) is shown in FIG. When transported to the contact portion between the upper seal roll 31 and the lower seal roll 32, the female seal 33 of the upper seal port 31 and the male mold 34 of the lower seal roll 32 are used. Then, an uneven sealing process is performed on the overlapping portion, and the two sheet-shaped papers are joined. When performing this sealing process, the control unit 70 controls the air cylinder solenoid valve 74 to operate the air cylinder 39, and pushes the lower seal roll 32 to the upper seal roll 31 with optimal pressure. Hit it. In addition, this sealing process is not applied over the entire overlapped part, as shown in Fig. 1, so that the handicapped elderly person or the handicapped can pull the joint part 2 apart only by pulling it lightly. Apply in place at predetermined intervals as shown. That is, the female die 33 of the upper seal roll 31 and the male die 34 of the lower seal roll 32 are not provided over the entire surface of the seal roll, but are provided in some places in the depth direction of FIG.

As a result, the sheet-like vapor is separated from the re-rolls 41 and wound up on the paper tube 6.

[Operation of Embodiment] Hereinafter, the operation of the device of the present embodiment will be described. Before operating the apparatus of the present embodiment, the roll-shaped paper is set in advance on a paper supply unit (not shown), and the lead provided at the tip of the roll-shaped paper is passed through the apparatus, It is wound around the paper tube 6 held by the winding unit 40. In this state, the operation panel 72 instructs the start of the operation of the device. As a result, various rolls are driven to rotate, The rolled paper is conveyed by an upper feed roll 61, a lower feed roll 62, or the like according to the lead portion. First, the roll-shaped paper is subjected to uneven processing by a known embossing unit (not shown). Next, when the mouth-shaped nipper is conveyed to the die roll unit 10 of the apparatus of the present embodiment, the hanging portion 3 necessary for the toilet seat sheet is stamped and formed. When the roll-shaped paper having the hanging portion 3 formed thereon is conveyed to the knife roll section 20, it is cut into a sheet-shaped paper. The cut sheet-shaped sheet is overlapped by the over rubbing section 50 so that the leading end of the downstream sheet-shaped sheet and the rear end of the upstream sheet-shaped sheet are overlapped. The sheet is conveyed to the sheet opening 30. In the sheet mouth portion 30, the overlapped portion is subjected to sealing, and adjacent sheet-shaped papers are joined. The joined sheet-shaped paper is sent to a winding section 40 and wound up on a paper tube 6.

When a predetermined number of the sheet-shaped paper 5 is wound on the paper core 6, a sensor outputs a signal, and the paper core 6 on which the sheet-shaped paper 5 has been wound is closed by an end port by a mechanism (not shown). It is sent on 64, 64. In this state, the operation of the device is temporarily stopped. The sheet-shaped paper wound around the paper tube 6 (pseudo-shaped paper-shaped paper) is connected to the downstream sheet-shaped paper, so that the end paper 6 4 and the winding section 40 are connected. Cut off the joint located between. This separation may be performed by an operator, or a separate unit and a separation mechanism may be provided. The separated pseudo roll-shaped paper is supported on end rolls 64 in a state where it can be transported to the outside of the apparatus. On the other hand, the distal end of the separated sheet-shaped paper is wound around a new paper tube by an operator. In this state, when the operator instructs the start of operation from the operation panel 72, the apparatus of the present embodiment repeats the above-described operation, and the joined sheet-like vapor is wound around the paper tube. In this way, a one-cut type paper, which is a pseudo roll-shaped paper in which the sheet-shaped paper is joined, is manufactured.

[Effects of the Embodiment] According to the one-cut type sheet paper of the present embodiment described above, it is possible to separate the sheet into a single sheet of paper simply by pulling lightly instead of cutting, so that it is difficult for hands. Even the elderly and disabled people can easily cut the rolled sheet into a single sheet of paper. Therefore, even if a toilet seat sheet is used to lay on a toilet bowl, A person who is leaning or handicapped can easily separate and use one toilet seat sheet from a roll that is rolled by himself. Also, compared to the case where the sheet-shaped paper is folded and stored, space can be saved by joining the sheet-shaped paper and winding and storing it in a roll shape. According to the one-cut sheet paper of the present embodiment, the sealing process is performed at room temperature without applying heat, so that the sealing process is simplified.

Further, according to the one-cut type sheet nipper of the present embodiment, the over rubbing portion is constituted by devising the lower blade roll of the knife roll portion and the upper seal roll of the seal roll portion. Because of this, the end portions of adjacent sheet-like vapor papers can be overlapped without separately providing a special device for the bar wrapping process, reducing the size and space of the entire device. Can be planned.

[Other Embodiments] The present invention is not limited to the above embodiment, and various modifications are possible within the scope of the gist. For example, how much pulling force can be used to easily separate by changing the depth of the unevenness, the area of the unevenness processing area, and the number of unevenness processing, according to the material of the vaporizer used, etc. It is not limited to the above-mentioned toilet seat sheet, and if it is rolled and stored, for example, a wrapping paper used in a store such as a kitchen used in a kitchen, a single wrapper, etc. Etc. can also be used.

Further, the overlapping section may be a device that is separate and independent from the knife opening section and the seal roll section.

Further, when joining the sheet-shaped paper, the rear end of the upstream sheet-shaped paper and the leading end of the downstream sheet-shaped paper are brought into contact with each other, and a joining small paper is placed on the abutting portion of the both. The pieces may be overlapped, sealed, and joined. When joining the sheet-shaped paper, an adhesive may be used if the separation is easy.

As described above, according to the present invention, the ends of the sheet-shaped paper are joined so as to be separable and wound into a roll to form a pseudo roll-shaped paper. Can be cut into a single sheet of paper by pulling it lightly, making it easy for elderly and handicapped people to use a single sheet of paper. It is possible to provide an uncut type paper that can be cut off. Industrial applicability
