Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a forming device for roll shavings, such as disposable paper shavings, and particularly for forming sheet-like materials such as paper or nonwoven fabric in the longitudinal direction. While continuously feeding, it is folded in half from the center in the width direction, and then cut at the appropriate point in the length direction.
The present invention relates to a roll-forming device such as a filter paper holder, which is used to moisten the cut pieces and then form them into a roll-shape.

[Prior art and its problems] There are two types of packaging for paper oshibori, etc.: the 1000-sided shape in a folded state, and the TL in a rolled shape.
As shown in Japanese Patent Publication No. 53-19264, the method for forming this roll-shaped paper oshibori involves a placing plate on which the oshibori paper is placed, and a roughly plate-shaped flexible sheet placed on this placing plate. There is a method in which paper is formed into a roll by relatively moving a cushioning material that has the properties of For endless winding, facing each other, belts are arranged, and as the upper and lower belts rotate in the direction of the appearance, the interval between the opposing surfaces is gradually increased, and the paper is fed in between to form a roll. The method of forming is mentioned.

However, with such conventional equipment, in order to generate the starting edge during roll forming, it is necessary to apply strong resistance to the starting edge of the roll. The embossed part was damaged.

In addition, the paper is soaked with water during the roll forming process or the previous process, and the repulsive force and frictional resistance of the paper vary greatly depending on the moisture content, which causes the diameter at the beginning of the roll to vary. Something happens. That is, if the winding starts with a small diameter, the circumference will be small, so the winding will rotate and move while being subjected to force for a long time between processes in the roll forming device, and therefore the roll-shaped oshibori will have a smaller diameter. In addition, if the diameter of the roll at the beginning of the roll is large, the circumference will be large, so it will be rotated between processes in the roll forming device in a short time. There are disadvantages such as the diameter of the roll is larger because it is carried out of the equipment by rotation, and the roll diameter varies because the roll forming equipment is not rotated at the same speed. Because of these differences, the speed at which they are transferred to the packaging equipment in the post-process is also different, which has been a cause of trouble in the packaging process.

In order to solve such problems, the applicant provided an engaging part configured to grip the edge of the sheet in a proper place, and attached the sheet to the surface through a hole communicating with a negative pressure chamber provided inside. It consists of a cylinder that is designed to attract the entire area, an endless belt with a rough surface and appropriate elasticity, and a con-hair, etc. that rotates in the opposite direction to the rotation direction of the cylinder located at the top. , in order to wind up the sheet sucked and transferred by the cylinder on a conveyor rotating in the opposite direction, and
It has been filed as No. 162907.

With this device, the variation in the roll diameter and the time difference between the winding device and the winding device process are reduced, resulting in high accuracy and eliminating problems in the packaging process, but winding sometimes attracts wet paper and requires rotation. However, the disadvantage of damage to the embossed part due to the frictional force between the cylinder rotating in the opposite direction and the conveyor rotating in the opposite direction has not been completely resolved.

It has been impossible to form rolls made of nonwoven fabric into rolls using conventional equipment because the nonwoven fabric is strong and thin.

Means for Solving Problem F 1 In view of this problem, the present invention consistently forms rolls from the base paper, and furthermore, uniformizes the winding diameter of the rolls with arbitrary dimensions. A roll-forming device that does not apply pressure to the embossed portion of the paper; and a shaft that holds the roll-up base paper with a tension controller device, and a roll-forming device that does not apply pressure to the embossed portion of the paper. a forming plate section configured to bend the pulled out strip-shaped base paper from a proper position in the width direction along the length direction; a feed conveyor configured to sandwich the folded strip-shaped base paper and feed it to the cutter section;
A cutter unit that cuts the strip-shaped base paper that is continuously fed from the feed conveyor from a predetermined position in the length direction to form a sheet of paper, and a roll-shaped formed body that holds the cut paper and that will be described later. A longitudinal wave conveyor configured to rotate in synchronization with the interval and movement speed, and a fixed amount of water or chemical solution disposed on the top of the longitudinal wave conveyor and sprinkled with a fixed amount of water or chemical solution in synchronization with the paper being transferred by the conveyor. A shower nozzle is configured as shown in FIG. , a shutter conveyor section, etc., configured to inherit the ri configured to form the paper into a roll shape from an appropriate position without pressure by the bending and reversing operation, further tighten the sheet by differential rotation, and then transport it to the packaging process.

Another example of the folding method is a method of folding the strip-shaped base paper from both sides in the width direction toward the center.

Since the feed conveyor 6 is constructed by disposing conveyors in which endless belts having elastic and rough surfaces are suspended, the gap between the opposing belts can be arbitrarily adjusted. The feed conveyor 6 is rotated by a drive section (not shown), and is configured to sandwich a strip of base paper folded in two in the width direction and feed it to the cutter section 7.

The top knife of the cutter section 7 is a rotary blade that is adjustable and fixed to the roll cylinder, and is constituted by a fixed knife placed opposite to the top knife. The cutter section 7 cuts the strip-shaped base paper continuously fed from the feed conveyor 6 into a predetermined length to produce sheets of wavy paper.

This gap adjustment is performed by placing a planetary follower 26 on the upper surface of the revolving belt conveyor 22 and applying appropriate pressure to the belt of the revolving drive belt conveyor 23 to adjust the belt to a state where it is clamped.

To explain the roll-shaped molded body 20 based on FIGS. 2 and 4, the revolving sheet 37 is made of a material with a rough surface and appropriate elasticity, and has a connecting shaft 21 and a planet at both longitudinal ends thereof. A fold is provided in a shape through which the follower series connection shaft 39 can be inserted, and the fold is firmly bonded. The length is approximately the same as that of a revolving planetary chain 35, which will be described later, and the width is large enough to accommodate the paper 2. The connecting shaft 21 is inserted into one of the folded parts of the revolving sheet 37 so that the revolving sheet 37 is located at the center of the connecting shaft, and rollers 36 and 36 are inserted into both sides of the connecting shaft. One end of the revolving planetary chain 35, 35 is rotatably mounted on the outside, and both ends of the connecting shaft 21 are inserted into a through hole at a predetermined position of the rotating chain conveyor 19, 19 with a spacer interposed, and rotatably mounted. are doing.

The planetary followers 26, 26 are configured to rotate (revolution) on predetermined orbits while being held between the respective belts of the revolving belt conveyor 22, 22 and the revolving drive belt conveyor 23. (Revolution in the explanation means that while the connecting shaft 21 is rotating in the tip state, the planetary follower 26 at the rear end of the roll-shaped compact 20 moves toward the tip from the connecting shaft 21 as a base point, and rotates on its own axis.) (means that it rotates together with the rotating chain conveyor I9)
The connecting shafts 40, 40, 40, 40, 40, 40, 40, 40, 40, 40, 40, 40, 40, 40, etc.

A plurality of paper sheets 8 are arranged at predetermined positions at appropriate intervals, and the longitudinal wave conhairs 8 are configured to supply the paper 2 to the upper surface in synchronization with the rotating speed of the roll-shaped molded product 20. .

The roll-shaped molded body 20 may be placed between the connecting shaft 21 and the planetary follower series connecting shaft 39 on an object made of a suitable material, or between the connecting shaft 21 and the planetary follower series connecting shaft 39.
It is also possible to bridge the space between the revolving planets 35 and 35 with a narrow plate.

Next, the shutter conveyor section 50 will be explained based on FIG. 5. The shutter conveyor 41 is constructed by suspending a plurality of endless elastic round belts between the opposing booths 1 and 42, and conveys the rolled molded products 20 at an appropriately faster speed than the rotating chain conveyor 19 attached thereto. rotate in the direction.

The shutter conveyor 43 is constructed by suspending an endless round belt having appropriate elasticity between opposing pulleys 44, and rotates at a faster speed than the shutter conveyor 41 in the opposite direction, that is, the working side is directed upward from downward. move.

Therefore, although the pulley 42 and the pulley 44 are mounted coaxially, their rotation directions are opposite to each other, and the pulley 4 is driven.

The shutter conveyor 45 has a plurality of belt-shaped elastic flat belts with rough surfaces suspended between the respective pulleys at appropriate intervals, and is directed in the opposite direction to the facing shutter conveyor 43, that is, the working side is upward. It is configured to rotate further downward. The shutter conveyors 43 and -46, 46 are arranged, and the shutters 46 and 46 are configured to vibrate from a substantially horizontal state to a substantially vertical state and open in synchronization with the rotation of the cutter section 7 by a cam (not shown). has been done.

Next, to explain its operation, the strip-shaped base paper pulled out from the base paper roll 1 reaches the forming plate part 5 via each small roll 4, and is folded in half from the center in the width direction at the forming plate part 5. It is formed into a shape and reaches the feed conveyor G. The feed conveyor 6 clamps the strip-shaped base paper and supplies it to the cutter section 7. The cutter section 7 cuts the strip-shaped base paper continuously supplied from the feed conveyor 6 into a predetermined length, and converts the paper into sheet-shaped paper sheets into longitudinally corrugated sheets onto the sewing conveyor 8 . The paper 2 being transferred by the sewing conveyor 8 is sprayed with water from a shower nozzle 9 during the transfer to impregnate the paper 2 with a fixed amount of water or a chemical solution, and the wetted paper 2 is moved to a rotating chain that rotates in synchronization with the paper 2.

moves in the A-2> direction as the rotating chain conveyor 19 rotates, but as shown in FIG. A planetary follower 26 is attached to the planetary follower series connection shaft 39 at the rear end, and the planetary follower 26 is connected to a revolving belt conveyor 22 having a faster circumferential speed than the rotating chain conveyor 19. Since it rotates and moves while being held between the drive belt conveyors 23, the roll-shaped molded product 2 is rotated as shown in (A-3).
0, the rear end curves sequentially and precedes the leading end, and a winding start is formed at a predetermined portion of the paper 2.

As the roll-shaped formed body 20 moves further and the rear end curves more than the leading end, the paper 2 rotates without being pressurized and is wound into a roll as shown in (A-4). , (A-5), resulting in a completely rolled oshibori 3. As the roll-shaped molded product 20 gradually curves, the roll-shaped oshibori 3 falls onto the shutter conveyor 41 at the point A-6), and is supplied between the shutter conveyor 43 and the shutter conveyor 45 by the rotation of the shutter conveyor 41. Ru. The supplied roll oshibori 3 is received by the shutters 46 and 46, but the roll oshibori 3 is The winding can be further tightened without loosening. When the shutter 46, which opens in synchronization with the cutter section 7, opens, the roll scraper 3 falls onto the conveyor 47 that transfers it to the packaging machine, and is transferred to the supply chain conveyor 48.
is transferred to the packaging machine.

At this time, depending on the speed of the rotating chain conveyor 19, etc., there may be a slight deviation in the position of the roll oshibori 3 falling from the roll-shaped compact 20 to the shutter conveyor section 50, but if the timing is early, the shutter conveyor 41 and is transported to the center, and conversely, when the timing is slow, it falls onto the shutter conveyor 45 and is transported back to the center.

The roll-shaped molded body 20 on which the roll oscillator 3 has been dropped has been reversed and the front and back sides have been reversed. As shown in (A-7) to (A-8), the planetary follower 26 lags behind the tip due to the differential braking effect due to the frictional resistance of the rubber lined on the inner peripheral surface of the revolving rail 27, and therefore When the roll-shaped molded body 20 reaches the planetary follower rail 25, the leading end is again in front, and while it moves further and goes around the idler wheel 13, it is further reversed and returns to the state (A-1).

The form of the roll roller 3, that is, the state at the beginning of the roll, differs depending on the state in which the paper 2 is sprinkled with water on the longitudinal wave conveyor 8. If water is sprayed from the shower nozzle 9 only to approximately half the area of the leading edge in the direction of travel of the paper 2 as in this embodiment, the wetted leading edge will be moved inwards from the appropriate position due to the curvature of the roll-shaped body 20 due to its weight. It is bent in the opposite direction (it may be bent outward depending on the mounting position), and is formed into a roll with the folded part as the beginning of winding. If water is sprinkled only on the edge of the paper 2, the end of the paper 2 will be the beginning of winding and will reach the water spray level.

[Advantageous Effects of the Invention 1] As described above, the present invention provides a shaft 10 for holding a winding base paper having a tension controller device, and a belt-shaped base paper pulled out from the winding base paper l from a proper position in the width direction to a longitudinal direction. A forming plate section 5 configured to bend the paper strip along the same line, a feed conveyor 6 configured to sandwich the folded strip-shaped base paper and supply it to the cutter section 7, and the sheet is continuously supplied from the feed conveyor 6. A cutter section 7 cuts the strip-shaped base paper from a predetermined position in the length direction to form a sheet-shaped oblique paper 2, and a cutter section 7 that holds the cut paper 2 and synchronizes with the arrangement interval and moving speed of the roll-shaped formed body 20, which will be described later. A longitudinal wave conveyor 8 is configured so as not to rotate, and a longitudinal wave conveyor 8 is arranged above the longitudinal wave conveyor 8, and is configured to spray a fixed amount of water or a chemical solution etc. in synchronization with the paper 2 being transferred by the conveyor 8. The shower nozzle 9 and the moisturizing paper 2 are placed on the upper surface, and during movement, the paper 2 is curved upward in the traveling direction sequentially from the rear end at a predetermined position, and the paper 2 is moved from the leading end to the appropriate position without pressure. A shutter conveyor section is configured to take over a roll-shaped formed body 20 configured to be formed into a roll shape in a state and a roll 3 formed into a roll shape, further tightened by differential rotation, and then transported to a packaging process. Since it is a roll-forming device such as a paper oshibori made of 50 or the like, as mentioned above, in order to generate the starting end during roll forming, in the conventional device, unless strong resistance is applied to the starting end, the rolling start cannot be started. Because of this, the embossed part at the start of the roll is damaged due to strong resistance, and the diameter of the start of the roll is different because the repulsive force and frictional resistance of the paper varies greatly depending on the moisture content of the paper. Therefore, since the roll forming device is not rotated at the same speed, the roll diameter varies.Furthermore, since the moving speeds are different, the speed of delivery to the packaging device is also low. However, in the present invention, the roll-shaped compact 20 is formed into a roll shape without pressure by the bending reversal action, which increases the roll diameter and causes problems in the packaging process. The force becomes very large, and there is no difference in roll diameter due to changes in water content, and there is no variation in roll diameter due to changes in operating speed, resulting in a uniform roll diameter. This eliminates the troubles caused by the synchronization difference caused by different roll diameters (different circumferences) when conveying to the packaging equipment, and materials such as cloth and non-woven fabrics, which were difficult to roll with conventional machines, can be rolled. It became easy to mold. In addition, in conventional pressure roll forming, the emboss is damaged, especially at the beginning of the roll, which is small in diameter and subjected to strong pressure, which not only causes damage to the emboss but also curls, which not only impairs the beauty of the product but also makes it difficult to open during use. However, according to the present invention, there is no damage to the embossment, and no curling occurs, resulting in a roll-shaped oshibori that is very easy to open. Furthermore, the present invention is not limited to the roll-forming of paper oshibori; it is also possible to roll-form oshibori made of cloth, non-woven fabric, etc., as described above; It is possible to form rolls of relatively short materials such as calligraphy wrapping paper and small-rolled shoji paper, and it is also possible to roll sushi rolls, etc., and it is also possible to form rolled oshibori from rolled base paper. Since the process is carried out in a consistent manner, efficiency is improved, product yield is high, quality is improved, and labor is saved, among other truly remarkable effects.
