Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a coreless paper roll manufacturing apparatus. More specifically, the present invention relates to a paper roll such as a toilet paper roll or a kitchen paper roll, and more particularly to a coreless paper roll manufacturing apparatus for manufacturing a paper roll without using a paper tube (core) as a core.

[0002]

2. Description of the Related Art A paper roll is manufactured by winding a strip-shaped raw sheet (hereinafter referred to as a web) drawn from a large-diameter raw roll having a diameter of several meters manufactured by a paper machine. At this time, there are a method using a paper tube (also referred to as a core, which is a cylindrical body made of cardboard) serving as a winding core and a method using no paper tube. In the former method using a paper tube, a paper tube is left at the center of a paper roll, and a web is wound around the outer periphery of the paper tube in a layered manner. When such a cored paper roll is used, since the paper core remains after the paper roll is completely used, it takes time to dispose or collect, and it is particularly large in places where business and schools consume a large amount of paper. It is inconvenient. On the other hand, a paper roll that does not use a paper tube is very convenient because there is no need to clean up the paper tube, but a winding method is very difficult because a core is not used in the manufacturing stage. That is, instead of using a paper tube, the web is directly wound around a long rigid core rod (winding shaft), but an adhesive cannot be used at the beginning of winding the web around the winding shaft. This is because if the starting end of the web is adhered to the winding shaft, the roll cannot be removed from the winding shaft at the end of winding. Therefore, the web must be wound around the winding shaft without using an adhesive. However, since the outer peripheral surface of the winding shaft is smooth and the friction between the web and the web is small, it is very difficult to wind the web. However, in order to manufacture a coreless paper roll, the web must be wrapped directly around the winding shaft, and the paper roll must have the required diameter (approximately 100 to 12 for toilet paper rolls).
It is necessary to wind it up to 0 mm, and about 110-130 mm for kitchen paper rolls.

[0003]

SUMMARY OF THE INVENTION In view of the above circumstances, the present invention makes it possible to take up a paper roll without using a paper tube as a core and finish it into a product roll of a required diameter.
Another object of the present invention is to provide a coreless paper roll manufacturing apparatus having high production efficiency.

According to a first aspect of the present invention, there is provided a coreless paper roll manufacturing apparatus, wherein a plurality of reels are detachably mounted on a circulating endless chain, and each reel passes through a winding zone in order. A paper roll manufacturing apparatus in which the web is wound directly on each of the winding shafts while the winding is being performed.The winding zone includes a guide that regulates a path of passage of the winding shaft, and a web on the winding shaft from a side opposite to the guide. A winding belt that comes into contact with a roll that is being wound and that rotates the roll in the winding direction is provided.Upstream of the winding zone, a winding shaft that enters the winding zone is pre-rotated, Attach an auxiliary belt to increase the outer peripheral speed of the winding shaft to the same speed as the traveling speed of the web, and guide the supply of the web to be wound around the winding shaft coming into the entrance side of the winding zone. Roll and the winding roll Le, characterized the contact position to increase the winding angle to the web of the reel, in that a position changing means for position change between a non-contact position away from the winding shaft. According to a second aspect of the present invention, there is provided the coreless paper roll manufacturing apparatus according to the first aspect, wherein a winding shaft that has entered the entrance side of the winding zone, on which the web has not yet been wound, and an exit side of the winding zone. And a cutter that cuts the web connected to the paper roll by rushing into the paper roll on which the web winding is completed, and a starting end portion of the cut web to the entrance side of the winding zone. And an air nozzle that blows out so as to be sandwiched between the winding shaft and the winding belt.
According to a third aspect of the present invention, there is provided the coreless paper roll manufacturing apparatus according to the first aspect, wherein a hollow shaft is used as the winding shaft, a suction hole is formed in an outer peripheral surface of the cylindrical portion, and the winding shaft enters the winding zone. Characterized in that suction connection means for connecting the hollow portion to a vacuum source is provided. According to a fourth aspect of the present invention, there is provided the coreless paper roll manufacturing apparatus according to the first aspect, wherein a glue spray gun for spraying a glue is provided on the web on the winding roll. In a coreless paper roll manufacturing apparatus according to a fifth aspect, in the invention according to the first aspect, the position changing unit is a swingable swing arm, and the winding roll is pivotally mounted on a tip of the swing arm. The swing arm when the swing arm is moved between the contact position of the winding roll and the non-contact position is located at a position that does not change the length of the web supply path. . Claim 6
In the coreless paper roll manufacturing apparatus according to the first aspect of the present invention, in the invention according to claim 1, a gluing apparatus for gluing a paper tube fitted on an outer periphery of a winding shaft is arranged at an appropriate position in a path where the endless chain circulates, and the winding is performed. A roll is detachably mounted on the position changing means, and mounting means for rotatably mounting the winding roll at a position not in contact with the winding shaft entering the winding zone is provided.

According to the first aspect of the present invention, the winding shaft before rotating into the winding zone is rotated by the auxiliary belt, and when entering the winding zone, the outer peripheral speed of the winding shaft is the running speed of the web. Therefore, the operation of winding the web around the winding shaft is reliably performed without the web sliding on the winding shaft in the winding zone. Further, since there is no need to rapidly start the rotation of the winding shaft in the winding zone, it is not necessary to use an expensive light-weight material winding shaft, and it is possible to use an inexpensive and high-strength winding shaft. Further, since the web is brought into contact with the winding shaft by the winding roll, and the winding angle of the web with respect to the winding shaft can be increased, the web can be wound around the web winding shaft without using an adhesive. For this reason, in order to pull out the reel from the paper roll after winding the paper roll, even if it is a coreless type in which the web at the beginning of winding cannot be adhered to the reel with glue, the web is surely applied directly to the reel. It can be finished into a wound paper roll. According to the second aspect of the present invention, when a cutter is inserted between the winding shaft on the input side and the paper roll on the output side in the winding zone, the web connected to the paper roll on the output side can be cut. The starting end of the web is sandwiched between the winding shaft on the entry side and the winding belt by the air blown by the air nozzle, so the rotation of the winding belt
The beginning of the web is wound around a winding shaft. by this,
Without using glue, wind the web directly on the winding shaft,
Can be finished into a paper roll. According to the third aspect of the present invention, the winding shaft that has entered the winding zone is connected to the vacuum source and sucks air from the suction hole, so that the web start end to be wound around the winding shaft can be adsorbed, and an adhesive is used. Even without this, the web can be reliably wound around the winding shaft. According to the fourth aspect of the present invention, after the first layer of the winding is wound around the winding shaft, the paste on the web on the winding roll is sprayed to form a layer at the beginning of the winding of the paper roll wound around the winding shaft. Since several layers of webs on the outside can be bonded to each other with glue, the portion is hardly broken down and functions as a core. For this reason, when used as a product after being wound up, it does not lose its shape, so that a user-friendly paper roll can be obtained. According to the invention of claim 5, even when the swing arm is swung to move the winding roll between the contact position and the non-contact position, the length of the supply path of the web wound around the winding roll is reduced. Since the web is not changed, the web is not cut or loosened by the movement of the winding roll, and the web winding operation can be smoothly continued. According to the invention of claim 6, it is possible to manufacture a paper roll with a core. That is, if the gluing means is arranged in the circulation path of the endless chain, the glue can be applied to the paper tube fitted on the winding shaft, so that the web at the beginning of winding can be bonded to the paper tube, and the winding roll can be moved by the position changing means. If it is detached from the reel and is rotatably mounted at a position where it does not come into contact with the winding shaft that has entered the winding zone by the mounting means, the web being supplied does not come into contact with the glue applied to the outer periphery of the paper tube. Only the first web is adhered to the paper tube, and the remaining web can be wound around the winding shaft without being adhered. Therefore, it becomes possible to manufacture a paper roll with a core.

Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a schematic side view of a coreless paper roll manufacturing apparatus according to an embodiment of the present invention, FIG. 2 is an explanatory view of a rotation start-up process of a winding shaft, FIG. 3 is an explanatory view of a web cutting process, and FIG. FIG. 5 is an explanatory view of a winding step of a starting end, FIG. 5 is an explanatory view of a web gluing step, and FIG.

In FIG. 1, reference numeral 1 denotes a winding shaft, and a plurality of winding shafts are held at equal intervals by a chain 2 wound around endlessly. The winding shaft 1 is directly wound with the web W, functions as a winding core during web winding, and is removed from the paper roll after winding is completed. The chains 2 have catches 3 attached at equal intervals, and the chains 2 with such catches 3 are arranged on both sides of the machine frame. By the catches 3 of the chain 2 arranged on both sides, the winding shaft 1 is detachably held at both ends. In addition, the chain 2 is guided at necessary points by a guide roller or the like (not shown).
The vehicle travels along a substantially square traveling route. As a mechanism for circulating the chain 2 in this manner,
A mechanism for rotating a drive sprocket around which the chain 2 is wound by a motor is used.

A winding zone A is provided on the left side of the circulation route of the chain 2 in the figure. In the winding zone A, a guide 4 is provided on the left side of the chain 2 in the drawing. This guide 4 holds the winding shaft 1 during the winding operation.
Is to guide the descending passage trajectory. on the other hand,
A winding belt 5 is arranged on the right side of the chain 2 in the drawing, that is, on the side opposite to the guide. The take-up belt 5 is formed by winding a belt 5b around a pair of pulleys arranged above and below. The belt 5b comes into contact with the web wound around the winding shaft 1, and rotates the paper roll being completed. For winding the web. Therefore, the take-up belt 5 is arranged obliquely, and the gap between the take-up belt A and the guide 4 is narrow at the entrance side and wide at the exit side. As the diameter of the paper roll R increases, a rotational torque can always be applied to the paper roll R.

An auxiliary belt 6 is arranged upstream of the winding zone A and immediately near the entrance side. This auxiliary belt 6
Also, a belt 6b is wound around a pair of pulleys arranged above and below, and the belt 6b comes into contact with the reel 1, and the reel 1
Is to rotate. The auxiliary belt 6 rotates the winding shaft 1 before entering the winding zone A in advance, so that the outer peripheral speed of the winding shaft 1 substantially matches the traveling speed of the web W described later. Therefore, no slip occurs between the winding shaft 1 and the web W, and the winding of the web W around the winding shaft 1 is reliably performed. Also, it is not necessary to rapidly increase the rotation speed at the moment when the winding shaft 1 enters the winding zone A,
It is not necessary to use an expensive lightweight material winding shaft, and even if it is heavy, an inexpensive metal winding shaft can be used.

Immediately before entering the winding zone A, a winding roll 7 is mounted on a swing arm 8 on the opposite side of the auxiliary belt 6 with the chain 2 interposed therebetween. The winding roll 7 has a function of guiding the supply of the web W, bringing the web W into contact with the outer periphery of the winding shaft 1, and easily winding the web W around the winding shaft 1 in the winding zone A. In order to achieve these functions, the winding roll 7 is rotatably supported at the tip of a swing arm 8, and the swing arm 8 swings around a fulcrum pin 8a at the base end. I have. The illustrated state is a state in which the winding roll 7 is in a non-contact position separated from the winding shaft 1 in the winding zone A, and can be moved to a contact position in contact with the winding shaft 1 by moving the winding roll 7 in the direction of arrow a. . Note that the swing arm 8 constitutes a position changing unit described in claims.
As the position changing means, other than the swing arm, any other mechanism may be used as long as the winding roll 7 can be brought into contact with or separated from the winding shaft 1.

The winding shaft 1 is constituted by a hollow shaft, and a suction hole is formed in the outer peripheral surface of the cylindrical portion. Further, a suction port connected to a vacuum source is provided at a winding start position which is the upper end of the winding zone A. One end or both ends of the winding shaft 1 that has entered the winding zone A comes into air-tight contact with this suction port, and constitutes suction connection means described in the claims. When air is sucked from the suction hole of the winding shaft 1 through the suction port, the web W can be reliably wound around the winding shaft 1 by the suction operation of the air.

The web W wound around the winding roll 7 is unwound from a raw roll (not shown), is sent via feed rolls 9, 9, and is fed via the winding roll 7. W is connected to a paper roll R being wound. Therefore, the winding zone A
The web W connected to the paper roll R runs between the entrance-side winding shaft 1 and the output-side paper roll R in FIG.
Is provided. The cutter 11 is supported by a swingable arm 12 and is normally held at a retracted position shown in the drawing by a stopper or the like (not shown). When the stopper or the like is removed, the cutter 11 protrudes to the right side in the figure by the action of a spring 13. Then, the web W can be cut.

An air nozzle 14 is disposed slightly above the cutter 8. The air nozzle 14 is used to connect the starting end of the cut web W to the winding shaft 1 on the entry side of the winding zone A.
The air is blown so as to be sandwiched between the winding belt 5. A gluing gun 15 is arranged above the winding roll 7. This gluing gun 15
Is to spray the paste on the web W on the winding roll 7.

In the winding zone A, the winding belt 5
, The web roll is being wound around the web 1, and the paper roll being formed is wound around the winding belt 5.
, The paper roll gradually becomes thicker and rolled to a predetermined diameter, and becomes a paper roll R. The paper roll R is conveyed along with the circulation of the chain 2 and is directed to the turret 16 arranged at the lower right of the chain circulation path in the drawing.

The turret 16 rotates so as to sequentially pass through four work stations I, II, III and IV.
I is a receiving station for the wound paper roll R. II is a sampling station, and reel 1
From the paper roll R is extracted. Then, the paper roll R is sent to a post-process (for example, a cutting process or a packaging process). III is an insertion station for inserting a paper tube into the winding shaft 1 when manufacturing a cored paper roll, but when manufacturing a coreless paper roll, the winding shaft 1 simply passes through. An engagement station IV is a station where the reel 1 is checked by the chuck 3 attached to the chain 2. Thereafter, the winding shaft 1 circulates together with the chain 2 and is used for the next winding operation.

Next, a method of manufacturing a coreless paper roll by the paper roll manufacturing apparatus having the above configuration will be described. FIG. 2 shows a rotation start-up process of the winding shaft 1. The winding shaft 1 that comes just before the entrance side of the winding zone A is rotated while contacting the belt 6 b of the auxiliary roll 6, and the outer peripheral speed of the web W
It is accelerated until it becomes the same speed as the running speed. Therefore, when the web W comes into contact with the winding shaft 1 later, no slip occurs. At the same time, as the chain 2 moves, the winding shaft 1 enters the winding zone A. FIG. 3 shows the state at this time. When the winding shaft 1 is sandwiched between the upper end of the guide 4 and the upper end of the winding belt 5, the swing arm 8 moves in the direction of arrow a, and the winding roll 7 is brought into a contact position where the winding roll 7 contacts the winding shaft 1. Moving. At this time, the web W is connected between the portion wound around the winding roll 7 and the paper roll R that has been wound (located on the exit side of the winding zone A). Here, when the cutter 11 is inserted, the web W is cut as illustrated.

Next, as shown in FIG. 4, when air is blown from the air nozzle 14, the starting end of the web W is sandwiched between the winding shaft 1 and the winding belt 5. In this way, when the start end of the web W is pinched even a little, the start end of the web is pulled up by the belt 5b and starts to pass between the winding shaft 1 and the winding belt 5. At the same time as the operation of the cutter 11, air is sucked from the suction hole of the winding shaft 1 so that the start end of the web W is aligned with the winding shaft 1 and the winding belt 5.
During this time, the web W is wound around the winding shaft 1 by the air suction action. On the other hand, since the winding roll 7 is located at a position obliquely above the winding shaft 1,
The position of the web W is closest to the winding belt 5 and the winding angle of the web W with respect to the winding shaft 1 is increased. In addition to this, the web W is securely attached to the winding shaft 1 by the air suction operation of the winding shaft 1. It is wound around.

When winding is started as described above, FIG.
As shown in (2), the glue is sprayed onto the winding roll 7 by the gluing gun 15 almost at the same time. When the web W onto which the paste has been sprayed reaches the reel 1, a little more than one layer of the web W is wound on the reel 1 below the lower layer, and the glued web W is wound on the upper layer. Will be done. When the layer of the web W with glue is solidified, the layer becomes hard and rigid, so that it functions as a paper tube. In other words, when used as a product, it plays the role of a core that retains the hole shape on the paper roll side when inserting the core rod of the toilet paper holder or kitchen paper holder that is currently used everyday. become. Therefore, the amount of the paste sprayed is sufficient as long as the amount of the wound layer forming the core is solidified.

As described above, when the winding starts in earnest, the winding roll 7 is moved to the non-contact position, and the web W is gradually wound on the winding shaft 1. The paper roll R is always in contact with the take-up belt 5 and keeps rotating. Therefore, when the paper roll R comes to the exit side of the take-up zone A with the movement of the chain 2, the diameter required for the product is reduced. Paper roll R is wound up.

The completed paper roll R is shown in FIG.
And is taken out from the winding shaft 1. In this state, the paper roll R is wound up to a diameter required for a toilet paper roll or a kitchen paper roll, but since its width is the same as that of the raw roll, the paper roll R usually has a length of several meters. doing. For this reason, when it is cut to a predetermined length by a log cutting machine in a post-process, it becomes a toilet paper roll or kitchen paper having dimensions to be shipped to the market. In this way, according to the present apparatus, the web can be wound directly around the winding shaft 1 without using a paper tube, so that a coreless paper roll without using a paper tube can be manufactured.

Next, another embodiment of the present invention will be described with reference to FIG. In this embodiment, a gluing device 20 is disposed at an appropriate position on the traveling path of the chain 2, in the illustrated example, at an upper portion of the traveling path of the chain 2. The gluing device 20 includes a glue tank 21 and a glue roller 22 disposed below the chain traveling path, and a pressing member 23 disposed above the chain traveling path. As the paper tube, a conventionally known one is used, and is inserted into the outer periphery of the winding shaft 1 at the position III of the turret 16. Then, it is delivered to the chain 2 at the IV position and circulates together with the chain 2. With the circulation of the chain 2, when the paper tube comes to the position of the gluing device 20, the paper tube on the winding shaft 1 is sandwiched between the gluing roller 22 and the presser 23, and at this time, a part of the paper tube is coated with the glue. . In the present embodiment, the winding roll 7 is detachably attached to the bearing support 8b of the swing arm 8. On the other hand, the bearing support fitting 2 4 mounting the winding roll 7 detachably is provided. The bearing support fitting 2 4 corresponds to the mounting means in the claims. When mounted the bearing support fitting 2 4 wound with a roll 7 it should be positioned not in contact with the winding axis 1 entering the winding zone A. That is, as described above, since the paper core with the glue is covered on the winding shaft 1, if the web W is brought into contact with the glue, the winding becomes impossible. In this embodiment, if the gluing device 20 is also removably mounted vertically or detachably, it can be used for both coreless and cored applications. That is, if the winding roll 7 is detached from the bearing support 8b of the swing arm 8 and attached to the bearing support 24, and the gluing device 20 is arranged as shown in FIG. A roll can be manufactured. As shown in FIG. 1, a coreless paper roll can be manufactured by attaching the winding roll 7 to the bearing support 8 b of the swing arm 8 and removing the gluing device 20.

[0022]

According to the first aspect of the present invention, since the winding shaft is rotated by the auxiliary belt, the operation of winding the web around the winding shaft is reliably performed, and an expensive lightweight material winding shaft is used. Since the web is not required and is brought into contact with the winding shaft by the winding roll, the web can be wound around the web winding shaft without using an adhesive. For this reason, a coreless paper roll can be manufactured. According to the invention of claim 2, the web can be cut by injecting the cutter, and the starting end portion of the cut web is sandwiched between the winding shaft on the entry side and the winding belt by the blowing air of the air gun, and the web is cut off. The starting end is wound around a winding shaft. This allows the web to be wound directly around the winding shaft without using glue.
According to the third aspect of the present invention, since the winding shaft that has entered the winding zone sucks air from the suction holes, it is possible to suck the web start end to be wound around the winding shaft, and to reliably remove the web without using an adhesive. It can be wound around a winding shaft. According to the invention of claim 4, several layers of webs outside the initial layer of the paper roll wound around the winding shaft can be bonded to each other with glue, so that the portion functions as a core. When used as a product, it does not lose its shape. According to the invention of claim 5, even if the winding roll can be moved between the contact position and the non-contact position, the length of the supply path of the web wound on the winding roll is not changed. The web can be smoothly wound up without being cut or sagged by the movement. According to the invention of claim 6, glue can be applied to the paper tube by the gluing means, and if the winding roll is rotatably mounted at a position not in contact with the winding shaft entering the winding zone, only the web at the beginning of winding is obtained. The web is adhered to a paper tube, and the remaining web can be wound around a winding shaft without being adhered. Therefore, it becomes possible to manufacture a paper roll with a core.
