Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a winding device for relatively thin or flexible sheets of paper, such as toilet paper or towel paper.

As a device for winding a fixed amount of base paper from a roll of base paper wound with a large amount of base paper onto another core, for example, a core system as shown in Japanese Patent Publication No. 48-281 No. 1 is used. In this case, a core frame longer than that is inserted, both ends of the core frame are supported by appropriate means, and the core frame inserted through the core is driven and conveyed. Coaco is made by rolling up a certain amount of base paper one after another, or 1% Kosho 48-139
As shown in No. 10, a core is supplied between a large number of winding rollers that are rotatably supported on their own axis and arranged in a cylindrical shape without using a core frame. 1.Thus, the rotation of the take-up roll causes the core to rotate once in the direction of the winding force of the base paper.1 The revolution of the take-up roll 1.Thus, the core is conveyed.
etc. are already known.

However, in the former case, the core frame must be inserted into the core in the first stage of the base paper winding process, and the core frame must be extracted from the log on which the base paper has been wound in the second stage, and the core frame is actually inserted into the core. In addition to the winding process, the above-mentioned extra steps and equipment are required, which makes the equipment extremely large and expensive.

The latter method has been devised to eliminate the need for a core frame, but in this case the core is supported in one valley of one of many small diameter winding rolls.

The core is rolled in the valley so that the core is thickened, and the core is shaped in such a way that the take-up roll revolves during the thickening of the roll and at the end of the roll, so the core is intermittently placed in the middle of the roll. It seems that we have to make one revolution.

There were drawbacks such as the small contact surface of the take-up roll that came into contact with the paper.

Therefore, in this invention, if the core is supported without using a mandrel frame, the core will be gradually moved during one winding of the paper. Furthermore, we have tried to provide a winding device for one sheet of paper that is devised so that the winding action for one sheet of paper is carried out through a large contact surface, one sheet of paper at a time, and that cuts the paper smoothly. It is something to do.

Another object of the present invention is to automatically (and extremely smoothly) wind the paper scrap at the beginning of winding around the core in one log wound around the core. The present invention aims to provide a paper winding device that
The gist of this is that a winding roll parallel to the winding drum is placed in front of the winding drum, which is supported horizontally at a suitable location on the machine frame, and one winding roll is placed on the machine frame. Freely displaceable 1
A horizontal bearing is mounted on the supported bearing frame so that the distance between the winding drum and the winding roll can be increased or decreased. and one upper part of the bearing frame which is supported by one part which is freely displaceable on one machine frame. The upper part of the bearing frame is horizontally supported, and the upper part of the bearing frame is supported by one part of the bearing frame, and one part of the bearing frame can be freely raised and lowered from a certain position below, and one part is urged upward. A support is provided with a roll, and the winding drum and the winding roll are connected to one drive source thereof,
A device for separating and discharging logs that have become thick and rolled on the receiving roll;
A paper winding device 1 is characterized in that a winding device is provided for winding the cut end of the paper that has passed between the core and the winding drum from above onto the core.

To explain the embodiment with reference to Fig. 1, in Figs. The drum 4 is a plurality of winding rolls disposed at the front of the winding drum 1, and the winding roll 4 is provided with a large number of grooves 4a in the normal direction of its cylindrical surface. A single shaft 51 is fitted between each roll 4 with an appropriate spacing between them, and the shaft 5 of this winding roll 4 is attached to the machine frame at the lower front direction of the winding drum 1. #1 above the bearing frame γ consisting of a pair of pivoting arms 6, above the 6 pivot points.

There are 8 horizontal bearings.

In this way, the distance A between the winding drum 1 and the take-up roll 4 can be increased or decreased. The air cylinder 10 is connected to the first winding roll 4, which is biased by a spring 9 in a direction to narrow the distance A between it and the first winding drum 1. The force is generated by the air pressure connected to the air cylinder.
One step has been taken to adjust this reduction.

This bearing frame T1 also has a stopper 1 for stopping the urging force of the spring 91 when the distance A is a certain distance 1, which is slightly smaller than the outer diameter of the core 11.
2, and this bearing frame γEζ selectively acts to increase the distance A.
An air cylinder 3 is provided oppositely for operating the bearing frame 1 in the direction of narrowing the bearing frame 1, pressing it against the stopper 12, and holding the bearing frame T fixed there.

The shaft 3 of the one-winding re-drum 1 and the shaft 5 of the one-winding roll 4, which are arranged parallel to each other as described above, are located at the fulcrum 6 position of the bearing frame 1 as shown in the figure. When the winding drum 1 and the winding roll 4 are connected to each other through the same interlocking system, the winding drum 1 and the winding roll 4 are driven in the direction of the arrow at the same circumferential speed. like being forced
It's happening.

A core supply device 15 is disposed above the gap A between the winding drum 1 and the winding roll 4 formed as described above.

The core feeding device 15 of the embodiment is configured such that the bottom plates 1 and 6a of the hopper 16 are pivoted on one side so as to be swingable. and a hopper 16 which connects the rolls 19i.

．． 1) On the other hand, the core 11 is composed of air cylinders 21a, 22a, etc. for alternately engaging and disengaging the core 11, and the core 11 guided from the inside of the hopper 16 into the supply gutter 20 is moved through two stoppers. When the stoppers 2122 are made to protrude alternately in a timely manner, the stoppers 2122 are dropped and supplied one by one onto the above-mentioned space A, and the engagement and disengagement of the stoppers 21 and 22 is performed in accordance with the rotation of the winding drum 1. The process is performed so that it is automatically performed periodically in synchronization with the amount.

Further, above the interval part A, a presser roll 23 such as a first-order presser roll 23 is provided which can freely advance and retreat downward from above.

In other words, 25 is a rotating shaft supported by a bearing 26 at a proper position G of the machine frame 2, and 2γ is a plurality of swinging frames arranged between each winding roll 4, which are pivotally supported from this rotating shaft 251. Each swing frame 21 is integrally connected at one free end with a stay shaft 28, and is connected to the bearing frame 2 of the presser roll 23.
The other free end side of each swing frame 2T has a presser roll 23 and several guide rolls 30.
The belt 31, which is suspended between the presser roll 23 and these guide rolls 30, rotates around the rotation shaft 25+.
The fitted roll 32f is rotated.

In this manner, the presser roll 23 of this embodiment is adapted to be brought into rolling contact with the core 11 at the interval A through the belt 31. The belt 31 is connected to a drive source for the winding drum 1 via a non-contact interlocking system, and in this embodiment, the belt 31 is rotated at the same circumferential speed as the winding drum 1.

The one-rotation shaft 25 is used as a pivot point.

The bearing frame 294 of the presser roll 23 connects the air cylinder 33, and is also provided with a stopper 35 formed by the piston rond end of the other air cylinder 34 to minimize the contraction of the air cylinder 33. Suddenly, the presser roll 23 side of the bearing frame 29 is upwardly displaced, and the belt 31 that is rotated around the presser roll 23, etc.

is the one interval part A, and the winding action position (the first
, position shown in solid line in Figure 6) is held, and the air cylinder 3
When the air cylinder 33 is further extended by 1 and the air cylinder 33 is extended by 1, the core 11 located above the 1-spacing part A is crushed by the pressing roll 23, that is, the core 11 is not rotated by 1. Belt 31: The belt 31 is pushed so that it is pushed down to the lower side of the gap A.

In addition, in order to allow the tip of the bearing frame 29 and the holding roll 23 as described above to freely move up and down across the core supply gutter 20, the supply gutter 20 is provided with the following:
A groove 20a is formed at one necessary location.

Next, 36 was pivoted 3γ at a proper position on the machine frame 2 below the winding drum 1.

A pair of swinging arms having a U-shaped side surface, and one free end of the pair of swinging arms 36 has a bearing roll 38 supported thereon.
The receiving roll 38 is located below the gap part A and is configured to be able to move up and down from below toward the gap part A. The lowering movement of the receiving roll due to this increased pressure causes the air cylinder 39 to reach its most contracted state or the swing arm 36 to move downward. The stopper 401 provided oppositely allows the 1.
It's happening.

Reference numeral 42 denotes a water tank located at a suitable location between the winding drum 1 and the receiving roll 38, and provided above the machine frame 2, and 41 indicates this water tank 42f.
This type of water holder is a roll that is hung horizontally so that a part of its surface can be immersed, and can rotate freely.
1 and a water tank 42 are arranged on the left side of the receiving roll 38 in the upper part of FIG. 1.

Note that the water roll 41 is preferably connected to a drive source 1ζ for rotating it.

Reference numeral 43 denotes a push-down arm which is pivoted at a proper position on the bearing frame γ in the upward direction of the first take-up roll 4, and is disposed once on the side of the first take-up roll 4; In order to swing the Presser roll 23
+Thus, the core 11 (slightly thickened), which is pushed down from above to the bottom of the gap A, is allowed to pass between its tip and the take-up drum 1.The side of the take-up roll. When the air cylinder 45 is compressed, the air cylinder 45 is moved down to the upper surface of the log 46, which is thickened to the bottom of the 1-space part A, and the -log 4
6, together with the receiving roll 3Bi that supports it, push it down one step under the pressure of the air cylinder 39.
The swinging arm 36 bearing the receiving roll 38 is the stopper 4
When the rotation of the log 46 is thereby stopped, the log 46 is rotated so as to be brought into contact with the water roll 41.

Next, 48 is the rotating shaft 3 of the 1-winding drum 1, the bearing 4

The air pipe 51 is connected to a compressed air supply source via a flexible tube (not shown), and this air pipe 51 is connected to a compressed air supply source to send air to this air pipe.

Air is blown upward in the tangential direction of the winding drum 1 from a number of nozzles 52 formed through the winding air pipe 51f.
I'm doing it so that I can squirt it out.

Also. The gear 48t to which the rotating arm 50 is attached is meshed with another gear 53, and the shaft 5 of this gear 53
When the locking motor 4 is energized, the air pipe 51 connected to the locking motor I (not shown) is upwardly displaced from the position shown by the solid line in FIG. 1 to the position shown by the chain line.

When the locking motor is deenergized, the air pipe 51 is returned to the position shown by the solid line by its own weight.

In addition, a stopper (not shown) for regulating the rotation range of the shaft 54+1 is provided.

Next, reference numeral 55 denotes a pair of rotating arms that are pivoted 56 to the machine frame 21 at the lower side of the receiving roll 38. The winding should be done by positioning it once between the air pipe 51 and the air pipe 51.

The bar 51 has been passed, and this bar 571.

The water is attached between the upper direction of the roll 41 (solid line in Figure 1) and the position where it can be pushed out by the push-down arm 43 toward the rolled fat log 46 at the lowest position (dashed line in Figure 1). ] It is configured to be able to swing freely.

In addition, 58 is an air cylinder connected to the single rotation arm 55 in order to operate the bar 51 over the above-mentioned range l, and 59
is a carry-out conveyor for receiving the logs 46 pushed out from above the receiving roll 38 by the bar 57 and carrying them out.

To explain about the following effects 1C, the paper winding device of this embodiment has the above-mentioned configuration.

Shrink the air cylinder 13 and push the bearing frame 1 to the stopper 12 with the air cylinder 131C; release from the attached state and take up one winding roll 4 force ξ Air cylinder 10
With the force of the spring 9 adjusted by the pressure of
While keeping this, the air cylinder 33 is minimized and the bearing frame 29 is
The side on which the presser roll 23 is pivoted is kept at the raised position shown by the chain line in FIG.
etc. are driven in the direction of the arrow at the same circumferential speed, and the hopper 1
When opening the stopper 22 disposed in the core supply gutter 20r of No. 6 and dropping one core 11, the distance A between the winding drum 1 and the winding roll 4 at this time is smaller than the diameter of the core 11. Since the ratio is also slightly higher, the core 11 is above the one interval part A.

Both the winding drum 1 and the winding roll 4 are received by one end, and are brought into contact with each other, causing them to rotate together.

In this state 1, when the air cylinder 33 is extended to the intermediate position and the bearing frame 29 is caused to collide with the stopper 35 where the air cylinder 34 is in the fully extended state, the presser roll 23 is moved as shown in the solid line in FIG. The belt 31, which has been lowered to the position and rotated around the presser roll 231, is placed on the core 1.
1 and is brought into contact with the upper surface of 1.

At this time, the stopper 35 is attached to the core 1 with the belt 31
1] I will make this connection.

The belt 31 pushes the core 11 and keeps the one-winding roll 4 in a position where the space A is not pushed wide by the core 111.

In this way, the zero winding drum 1, the winding roll 4, and the presser belt 31 are brought into contact with each other, and between the core 11, which is held between them and given rotation, and the first winding drum 1. Then, one end of the paper 60 that has passed through the guide roll 61 is guided, and while supplying air to the air pipe 51, one paper 60 is connected to the core 11 at one interval A when raising it. The paper 60 that is blown between the winding rolls 4 and passes through them hits the belt 31t and is wound around the core 11 (FIG. 6).

In addition, in the above-mentioned Example 1, the presser roll 23 and the belt 31 were rotated, but such a belt 3
1 is not present, and the presser roll 23 is in direct contact with the core.

The leading edge of the paper 60 that has passed through the diameter of the presser roll 23 and passed between the take-up roll 4 and the core 11 for one time.

Press the pressing roll 231 and rub it once so that it is wound around the core 11.

When the paper 60 is wound onto the core 11 in this manner, the core 11 becomes thicker at this position while pushing back the winding roll 4 against the bias of the spring 9.

The tightness of the winding at this time is adjusted by the air pressure supplied by the air cylinder 10+.

When the core 11 becomes slightly thicker and the center of the core 11 approaches the line connecting the centers of the winding drum 1 and the winding roll 4, the air cylinder 34 is contracted and the stopper 35 is moved back. .

When the air cylinder 33 is extended and the bearing frame 29 is rotated, the core 11 is pushed by the presser roll 23 and the belt 31 and passes through the gap A.

It is pressed onto the receiving roll 38 below.

When the core 11 is positioned below the gap A in this way, the air cylinder 13 is extended to push the first winding roll 23 back toward the winding drum, and the bearing frame 1
7), the air cylinder 33 is contracted to the maximum, and the presser roll 23 is
When returning to the upper solstice position again, the core 11, which has been slightly wrapped with one paper 60, is pushed by the receiving roll 38I and rotates once between the winding drum 1 and the winding roll 4. It will be forced from below.

While leading up to the above. The core 11 that has continued to wind one paper 60 by continuing to be rotated by at least two or more of the winding drum 11 winding roll 4 or presser roll 23 continues to be rotated by the receiving roll 38. At the top, the winding drum 1 contacts both the winding drum 1 and the winding roll 4, and is stably supported at three points.

During this thickening, the primary core 11 force ξ hopper 16
The core 11 is supplied above the gap A, and the core 11 is idled there.

Next, when the log 4G is obtained by winding paper of a predetermined length with 11 thickened cores on the receiving roll 38.

When the air cylinder 45 is contracted and the push-down arm 431 is pushed down, the log 46 is pushed down to the position where the receiving rolls 38 reach one clove point.

The log 46 comes into contact with the roll 411 when wet.

At this point, when the first winding is supplied, the air pipe 511 is supplied with air, and at the same time, it is driven upward once.

Paper 60 breaks at the part where it is weakened by being soaked with water.

The side stump of the winding dom 1 is blown upward, and
It is folded into one fold and sent between the primary core 11 and the winding roll 4.

The stump of the log 46 is pasted with water on the surface of the log 46.

Subsequently, when the air cylinder 58 is extended and retracted one time.

The bar 51 hits the log 46#, and the log 46 is pushed out from above the receiving roll 38 onto the carry-out conveyor 59.

It goes without saying that the next core 111 above the interval A is wrapped with one sheet of paper in the same manner as described above.

In this way, the core 11 is fed from the paper winding device 1 of the present invention to the upper part A intermittently.
The device of the present invention uses the upper and lower parts of the EC1 interval part A to wrap the paper that is continuously fed without stopping.
From the above configuration E, in the above manner,
Since the paper 60 is wound around the core 11, the core 11 is sufficiently wound and thickened at the lower part of the gap, and just before it is lowered, the rotation speed of the entire device, including the feeding speed of 1 to 6 sheets, is changed from high to low. The core 11 is rolled slightly thicker above the primary log interval A, and the core 11 is kept at a low speed for 1 second until it is moved below the interval A. When driving at high speed, only after the upper 1st holder is stopped and until it becomes fully thickened, above the 0 interval section A.

By reducing the length of the double-fold winding into the core 11, it is possible to roll one paper 60 smoothly and neatly into the core. It's a touching thing.

The winding device of the present invention is designed to perform the movement due to the thickening of the roll by one log as described above without using a core frame or the like, so there is no need for a device for inserting and removing the core frame. The winding device of the present invention has the advantage of being able to be constructed in a compact manner, and the winding action for one sheet of paper is always one, and the winding device of the present invention has the advantage of being able to wind up one core or log by a drum and a winding roll. The advantage of this is that the winding of the paper onto the core can be carried out very smoothly and satisfactorily. have.

Further, in the winding device of the present invention, the receiving positions for the core around which one sheet of paper is wound are located one position above and below the gap between the one winding drum and the winding roll.

The initial winding of paper and the subsequent main winding thickening.

The winding process is performed by switching between the upper and lower two positions, and the winding at the lower position is performed by taking one roll of the core and transferring it to the lower space between the re-drum and the take-up roll. The receiving roll is moved downward, and the receiving roll, which is forced upward once, is stopped and carried out once, so at this position, the amount of thickened log to be wound reaches the predetermined amount, and the base paper is finished. The log, which became thicker by one roll when it was cut, is placed at the bottom of this winding device.

It is easy to release from above the receiving roll.
This can be taken out of the device.
