Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for winding webs of sheet material such as paper, plastics, metal foils, etc., and more particularly to a method and apparatus for winding webs of sheet material such as paper, plastics, metal foils, etc. This invention relates to a device for rewinding a large roll into a small "web roll" (in this invention, this refers to "a web wound around a core in the form of a roll").

This application is related to co-pending Application No. 186002 to Fabico Pelini, which describes web perforation and other types of web separation devices, but specifically relates to a new method for separating webs without cutting them. is directed towards. This application discloses that as the web is stretched between a fully wound "web roll" and a core brought into close proximity to the completed "web roll" and in contact with said web, In order to calculate the number of turns and determine the web length, a device is described for cutting the web at precise locations.

From the description below, it will be seen that the web is "snapped" between the acceleration roll and the deceleration roll, and in this regard, the apparatus of the present invention is capable of using knives, vacuum boxes, pneumatics, and effective web separation. It will be appreciated that this is different from conventional rewinding machines using similar equipment.

In the process and equipment for rewinding large parent rolls of paper into small consumer-sized "web rolls,"
One of their defining characteristics is the precise separation (cutting) of the web into a predetermined number of wraps or sheet lengths, while at the same time ensuring that they are continuously wound into the next "web roll". In order to achieve this, the leading edge of the newly formed web is transferred to a new core. At the same time, the paper roll that has just been completed must be discharged from the winding area.

Separating the web, (winding) securing the "tail" of the web to the completed "web roll", securing the new tip of the web to the new core, and transferring the completed "web roll" to the machine. The unwinding must be done without slowing down the machine, which is running at very high speeds.

Many proposals have been made in the past to accomplish such web separation and switching. Of considerable importance are Italy (No. 963047) and the United Kingdom (No.
This is the Perigny method described in the series 800 Perigny machines, as described in a patent issued to Perigny in 1435525).

The outline of the present invention is as follows. That is, in the high-speed machine of the present invention, transfer is performed by using glue (adhesive material) or other methods to secure the web to the core (or to secure the tail of the web to the outer peripheral surface of the "web roll"). It will be completed without any need. However, the web is not cut in any way before the portion of the web contacts the core on which the soon-to-be-formed "web roll" is wound. In the present invention, the web is finished "web rolled" with the front part of the web still intact.
During the winding process, it is caught between the new core and the take-up roll. However, the rotational speeds of the take-up roll, core and completed "web roll" are precisely controlled such that a tensioning action occurs on the web between the completed "web roll" and the core. , pruning, tearing, or tearing the short space between the new core and the completed "web roll."

The paper web may be provided with a continuous line of holes across the paper web to define the limits of its own sheet in the completed paper, one of these hole lines being at the center of the winding. Although arranged in short spaces between completed "web rolls" (to help separate the web when the sheet is "snapped" in that area) The array of such holes and their locations are not critical to the invention, and separation of the web may be performed without any sheet holes in the web.

In the present invention, a web take-up roll, a diameter control roll, a winding core and a completed "web roll" are used.
The rotational speed of the web is individually and precisely controlled at the precise moment when the web is being separated, in order to cause the tension of the web and the movement of the core and rolls, thereby causing the web to break apart. .

In operation of the mechanism of the invention, the web is fed from a parent roll through a perforation and a first take-up roll. The second take-up roll is placed at a distance slightly smaller than the outer diameter of the core on which the web is re-wound.
It is arranged adjacent to the take-up roll.

The core is brought close to the two rolls,
Different speeds are generated between the two rolls so that the core is forced into the throat between the two rolls, creating a pinching effect on the paper web between the core and one of the rolls. do. As the core and web continue to wind, a "web roll" is formed on the core,
This winding process continues with the two rolls and the winding core rotating at the same circumferential speed.

A diameter control roll is carried supported on top of the paper winding roll to precisely control the diameter of the "web roll", and the circumferential speed of the diameter control roll is also controlled by the winding operation. is the same as the circumferential velocity of the paper web.

When it is time to discharge the completed "web roll" and start a new "web roll", the speed of the rolls is once again precisely varied to create different speeds between the three rolls. This accelerates the completed paper "web roll" from between the diameter control roll and one of the take-up rolls, causing itself and the newly introduced core to move between the core and the other take-up roll. Where the web is pinched between the rolls, tension is created in the web of paper and the area between the core and the completed "web roll" causes the paper to tear or tear. All of this can be accomplished with or without glue to hold the "tail" of the completed "web roll" in position relative to the outside diameter.

Vacuum or air jets may be used to aid in transfer, but these are not necessary.

As will become apparent from the foregoing discussion, and especially after reading the specific description that follows, a defining feature of the invention is the provision of different speeds for each of the drive roll, diameter control roll and paper web. It must be applied accurately and at the appropriate time.

Therefore, the first object of the invention is to provide a continuous, high speed automatic rewinding machine (this machine is not equipped with a cutting mechanism) and a fast rewinding machine at precise locations along the web. It includes a web and roll control mechanism that cuts the moving paper web.

Another object of the invention is to provide a web separation mechanism of a rewinding device that can be used with or without glue to secure the leading edge of an advancing web to a newly positioned core. That's true.

Another object of the invention is to use only the differential rotational speed mechanism of the drive rolls to create tension in the web and thereby cut (separate) the web at precise locations along the web. A web separation device is provided.

In view of the foregoing and other contemplated objects, a knowledge and better understanding of the present invention may be achieved by reference to the following specific description.

BRIEF DESCRIPTION OF THE DRAWINGS For the purpose of illustrating the invention and illustrating the invention, preferred embodiments are shown in the accompanying drawings, in which: FIG. However, the various means constituting the invention may be arranged and configured in various ways, and the invention is not limited to the precise arrangement and arrangement of the means as shown and described herein. It's not a thing.

FIG. 1 shows a rear stand or frame 31 that supports the rewinding device of the present invention.

A web 34 (the web refers to a sheet-like material such as paper, plastic, or metal foil as described above, but in this embodiment, the case of a web is explained) fed in the direction of an arrow 35 is received, and the web is fed in the direction of an arrow 35. A guide roll 32 and a pivot roll 33 are supported at the upper end of the frame to guide the web downwardly towards the rewinding mechanism.

The web 34 is conveyed to the roll 32 from a rear stand or support holding a large parent roll;
The parent roll is constructed and arranged so that it is rotated and the web 34 is re-fed therefrom at the appropriate tension and desired speed.

As the web descends from the swirl roller 33, it passes a perforation location 36, which
so as to create a series of perforations across the web as it passes between a non-rotating member 37 supporting a cutting knife or wing 38 and a rotating knife roll 39 to which is mounted a number of cutting knives 40. Designed.

The rotation of the cutter roll 39, which brings the wings 40 into contact with the stationary perforation vanes 38, increases the linear velocity of the web as it descends through the perforation site to place appropriate perforation lines every few inches across the paper. will be adjusted accordingly.

The perforation locations are shown more clearly in FIG. 17, and the mechanism for rotating the position of the rotatable roll 39 is shown more clearly in FIG.

Thus, if it is desired to modify the position of the perforation line in the throat 47, a suitable drive mechanism operated by a cam or other similar
Adjust the position of the shaft 41 shown in the figure. As a result, the turning rolls 42 and 43 are turned around the axis of the roll 41. As a result, the drive mechanism 44
is driven, and the drive mechanism 44 is indirectly connected to the rotor holder 39.

Such adjustment moves the wing 40 forward or backward, thus changing the position of the perforation line in the throat 47 and thereby precisely locating the perforation line at the point where the web is to be snapped. will be held.

After the web 34 has been perforated with successive rows of perforations, it is lowered from the perforation site 36 and brought into contact with the surface of the first winding roll 46.
As shown in FIG.
by the lower surface of the first winding roll 46
and a second take-up roll 48 juxtaposed thereto, into a throat 47 formed by the separate surfaces thereof. The above relationship between rolls 46 and 48 is more clearly shown in FIG.

The width of the throat 47 between the rolls 46 and 48 is slightly less than the outer diameter of the core 49, which is placed into the throat 47 and after the web has passed beneath the roll 46. A web 34 is wound over it.

Referring again to FIG. 1, a hopper or trough 50 is shown above the frame 31, the hopper or trough 50 containing a number of cores or tubes 51.
constructed and arranged to hold.
This storage container or hopper 50 is provided with a vertical guide slot or trough 52 arranged radially downwardly, so that the pile of the winding core 51 is
It descends further to the gluing place 53.

The gluing station 53 consists of a rotating member 54 having a number of grooves 55, three of which are shown in FIG. 1 and spaced 120 DEG from each other.

The groove 55 is surrounded by a number of rider rolls 56 on which the core 51 falls when in the uppermost position, as shown in FIG.

When the rotating member 54 is rotating in the direction of arrow 57, the core located in the uppermost groove 55 is conveyed past a gluing station 58 with a rotating gluing wheel 59. As the core passes through the rotating wheel 59, the wheel 59 rotating in a vat of sticky material 60 directs the adhesive from the vat towards the surface of the core at a selected location determined by the rise of the rotating wheel. and thus rotate the core relative to the guide member 56 to apply circular strips of glue to multiple locations along the length of the core 51.

Thereafter, by continuous rotation of member 53 in the direction of arrow 57, core 51 is brought to position 61;
From there, it is ejected by gravity along the chute 62 and comes to rest at a position 63 indicated by a dotted line at the lowest point of the chute 62.

At an appropriate moment, the core lifting mechanism (specially shown in FIG. 13) lifts the core 51 from position 63 and brings it to the throat 47, where the core 51 is lower than the width of the throat. Due to the slightly larger diameter of the core, the core is clamped between rotating first and second take-up rolls 46 and 48.

In more detail below, the winding core 51 is connected to the arm 65.
At the moment of being pushed into the throat 47 by the upper push wheel 64, the circumferential speed of the roll 48 is reduced with respect to the circumferential speed of the roll 46, so that the core 51 moves between the two rolls in the direction shown by the arrow 66. be rotated.

During this rotational movement, the web 34 is clamped between the core and the first take-up roll 46, the glue is transferred from the web to the web, and the web is held tightly between the core and the roll 46.

A rising arm 65 for bringing the winding core to the throat 47
The timing of is carefully controlled by cam 67 and follower cam 68, and this timing is maintained accurately with respect to the rotational speed of the other rolls in the machine and the linear speed of web 34.

As soon as the web 34 is wrapped around the core,
By the continuous rotation of rolls 48 and 46 (which are differentially driven so that the fast speed of roll 46 is maintained relative to the web and core), the core is moved from throat 47 to the top of roll 48. It is rotated in position, where it continues to make contact with rolls 48 and 46, increasing in diameter as shown by the dotted lines in FIG.

Immediately after the core has passed from the throat 47 to the top of the roll 48, the rotational speed of the roll 48 is increased until its circumferential speed is the same as the linear speed of the roll 46 and the web 34; and 4
While maintaining contact with 8, continue winding onto the core with a "web roll".

As can be seen in both FIGS. 1 and 2, the diameter controlling roller 69 is connected to the second take-up roll 4.
an arm 7 provided on 8 and rotating around an axis 71;
Supported by 0.

The diameter control roll 69 described above is comprised of rolls 46 and 4.
8, the circumferential velocity of diameter control roll 69 is arranged to tightly contact the upper surface of the web "web roll" as it is wound between rolls 46 and 8, and in this way the circumferential speed of diameter control roll 69 is controlled by the roll 46 during the winding operation. It is the same as the circumferential speed of 48. Moreover, the diameter control roll 6
The mechanism controlling the rise of 9 is shown in FIG. In this figure, the cam 72 is connected to the connecting rod 75.
It is supported against a follower cam 73 on an arm 74 that raises the cam. The upper end 76 of the shaft 75 is suitably connected via a link for pivoting the arm 70 about the shaft 71 under controlled restraint, thus defining and defining the limits. , controls the diameter of the "web roll" wound around the core.

Connecting rod 75 is connected to rod 75 by sliding bracket 202. Pivot 204 connects bracket 202 to rod 75. Bracket 202 can be moved along arm 74 by turning handle 200 and screw 201, thus changing the distance between follower cam 73 and pivot 204 and the distance between pivot 204 and pivot 204.
Change each dimension of the distance between 03. Such an arrangement allows the diameter of the "web roll" to be adjusted while the machine is rotating and allows the diameter of the "web roll" to be changed without stopping the machine.

Furthermore, the rotational speed of the diameter control roll 69 is carefully controlled for both acceleration and deceleration, and the mechanisms provided for this acceleration and deceleration are shown in FIG. As specifically shown in Figure 15,
Shaft 71 is rotated under the control of pulley 77. This pulley 77 is wrapped by a drive belt 78 which passes around a number of guide pulleys, two of which (79 and 80) are mounted on a bracket 83 which is pivoted about a shaft 82 on which it is mounted. The bracket 83 is mounted on a pivoted arm 81, and the bracket 83 itself is supported on a shaft 84.

The cam 85 is a driven cam 8 attached to the arm 81.
6 and allows the arm 81 to rotate around an axis 82, and in this way the roll 77
Moving the belt 78 about the axis of the diameter control roll 69 either increases or decreases the rotational speed of the diameter control roll 69.

During most of the operation of the device, the web 34 is wound onto the core to the preselected position shown in FIG.
Rolls 46, 48, and 69 have similar surface speeds (ie, similar linear speeds).

When it is desired to discharge a fully wound "web roll" from the position shown in FIG. is also modified to be larger, and the "web roll" is then discharged from the position of FIG. 2 into the "web roll" receiving hopper 87 of FIG. 19.

When the wound "web roll" is discharged into the hopper 87, the hopper 87 is suitably rotated about an axis 88 by an arm 89, which is pushed by the cam 91 against the driven cam 92. is moved under the influence of a lever 90 which is The arm 89 rotates the hopper 87 in the direction of the arrow 93 and transfers the "web roll" to the "web roll" transport conveyor 94.
put it on top. The hopper is then returned to the position of FIG. 19 in preparation for receiving the next "web roll" of web.

The acceleration and deceleration mechanism for the second take-up roll 48 is shown in FIG. 16, where a belt 95 wraps around the roll 48 and a number of guide rolls 96, two of which are , an arm 99 supported about an axis 100 under the influence of a cam 101, said cam 101 being supported by a driven cam 102 attached to arm 99.
It supports it against.

If desired, cam 101 rotates arm 99 to axis 10.
It is rotated while being pivoted around 0. The positions of rollers 97 and 98 are then changed, and the relative movement of roll 48 is
can be accelerated or decelerated as desired.

As can be seen from the foregoing, the rolls 46,
The relative speeds of 48, 69 can be precisely and carefully controlled with respect to the linear speed of the web as it passes through the rewind mechanism. As previously mentioned, under high and low conditions, the linear velocity of the web and the peripheral velocity of rolls 46, 48, 69 are the same.
However, when it is desired to direct the core to throat 47, roll 48 is decelerated relative to roll 46.

At the same time, the deceleration of roll 48 relative to the rotational speed of roll 69 causes a strip or length 104 of web material 34 to be removed between the center and the position where roll 46 pinches the web between them and the upper surface of the final roll. The "web roll" is moved from its final position shown in FIG. The positions for creating such tension and web are as shown in Figures 3 to 7.
This can be clearly seen by including the figures 8 to 12 just mentioned.

In FIG. 3, the glue conveying core 49
is brought to a small spaced position at the entrance of the throat 47 while the rolls 46, 48, 69 are operating at the same circumferential speed.

The "web roll" 103 is just finishing its winding operation under the influence of three rolls. As the tail pusher 65 moves the core 49 further into the throat 47, the web 34 is tightened between the core 49 and the roll 46, while the roll 48 pulls the core along with it into the throat. It is decelerated while being rolled forward.

At this moment, the "web roll" 103 is also decelerated as the roll 48 is decelerated to the position shown in FIG.
It begins to be moved from the winding position. In this position, the length 104 of the web 34 is aligned with the "web roll" 10
3 and core 49.

At the same time, the roll 69 is "web roll" 10
3 remains in position between rolls 48 and 69, it is decelerated to bring it to the same circumferential speed as roll 48.

As can be seen in FIG. 6, the rotational speed of roll 69 is increased relative to roll 48 in order to move the "web roll" 103 further away from the throat, and thus, in FIG. The web 34 is snipped or torn along the length 104 as shown in FIG.

When the core 49 is introduced into the throat, it is transferred to the paper 34 along the viscous peripheral surface on the core, the part of the web that forms the winding section 104 . After the web is separated along section 104, some of the viscous material accumulates on tail 105, and some
The viscous material builds up on the leading edge 106 of the web, thus causing the trailing portion 105 to "web roll".
It is used to roll the tip 106 to the winding core 4.
It can be used to attach to 9.

When the roll 69 continuously rotates at a faster speed than the roll 48, the "web roll" is changed to "web roll".
into the receiving hopper 87 while at the same time, due to the slow rotational speed of roll 48 relative to roll 46, the core and web, with the web held tight to the core by a viscous material. Move from the throat to the holding position.

As a result, the cycle is a new "web roll"
The process is repeated until the paper is wound to the appropriate diameter and web length, and then the cycle of separation and transfer is repeated.

It is noted that the transfer procedures and mechanisms shown in Figures 3 through 7 may be used with or without adhesive, and the choice of whether or not to use adhesive depends on the type of web material. It must be mentioned that it depends on several factors, including work speed.

8-12, procedures similar to those shown in FIGS. 3-7 are shown.

In FIG. 8, rolls 48, 46, 69 are
The "web roll" 103 is wound to a suitable diameter and rotated at the same circumferential speed until the core 49 is guided to the entrance of the throat 47.

In FIG. 9, roll 48 is decelerated to bring core 49 into the throat and into contact with web 34. In FIG.

The deceleration of rolls 48 and 69 also moves the "web roll" 103 from the throat to the position shown in FIG. 9, creating a length 104 of the web 34 between the core 49 and the top of the "web roll". .

Immediately, roll 69 is reduced relative to the rotational speed of roll 48 to move the "web roll" 103 toward the throat, creating a loop or slack 105 in the web portion 104.

At this time, the web also begins to wind around the core 49,
As shown in FIG. 11, the leading edge of the web is captured between the core and roll 48 at location 106, and the leading edge of the web is caught between the tabs or in the sheet between the core and roll 48 and on the "web roll" 103. This creates tension in the web at the top.

As shown in FIG. 12, the roll 69 is accelerated once more, cutting the paper into pieces, or tearing the paper in taut loops 105, and continuing to wind the web onto a new core at the throat. The completed bundle is moved away from the throat under successive and different speeds of both rollers, with roll 69 moving faster than roll 48.

From the foregoing, it can be seen that the different speed control mechanism described above includes means for selectively controlling the circumferential speed of the rolls 46, 48, 69 in the same way as the linear speed of the web 34, and is precisely controlled so as to be referred to as a "web roll". ”1
03 can be held in a "dancing" position between rolls 48 and 69, as desired to create enough slack or loop 105 for the tip to be tightened between the core and roll 48. The ``web roll'' 103 is moved towards or away from the throat, while the web is still wound onto the ``web roll'' 103, and the ``web roll'' is then moved up and down along the length 105. The roll 6
9 is accelerated appropriately and the winding cycle is then repeated.

Although selective means for adjusting acceleration and deceleration of the various rolls and controlling the position of the diameter control roll have been illustrated and described, different drive mechanisms such as conical drive pulleys, PIV drives, and the like may alternatively be used. It should be understood that all aspects of the present invention are within the spirit of the invention.

In FIG. 12, optional auxiliary guide belts for rolls 48 and 69 are shown in dotted lines. These belts extend over the surface of each roll so that "web roll" 103 is connected to rolls 48 and 6.
``Web roll'' 1 like a ``dance'' between 9
03 is provided with a surface along which the loop 105 and the web length 104 are guided.
The rotation and movement of the ``web roll'' is controlled reliably so that the ``web roll'' is shifted back and forth to make.

The invention may be embodied in other specific forms without departing from its spirit and nature, and it is therefore desirable that such embodiments be considered in the same context as illustrated. It is preferable, therefore, that open-ended reference be made to the claims, rather than to the foregoing, to indicate the scope of the invention.
