Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel web splicing device capable of splicing old and new webs together quickly and reliably while minimizing splicing allowance.

Load rolls of webs of paper, sheets, films, cloth, foil, etc. into various web processing equipment.

The process of feeding the web from the roll to the processing side and subjecting it to the required processing is widely practiced in industry.
For example, printing paper for rotary printing presses.

Films and the like used as packaging materials in bag-forming-fill-sealing machines are continuously fed out from their original rolls and consumed in large quantities. When the web wound into a roll is fed out for various processing, when the roll currently being used for consumption is used up, it is necessary to quickly replace it with a new primary roll. . Also, the standards (dimensions) are different from the web currently in use.

It is also necessary to make changes to the web (quality, etc.) through order change directives. A web splicing device, generally called a splicer, is used as a means of automatically splicing the web end of the old roll and the web start of the new roll without stopping the operation of the processing equipment when replacing the web. is preferably used. The methods of joining the old and new webs are: ■ one in which the speed of the new web is synchronized with the running speed of the old web;
■There are cases where the new web is spliced while the old web is stopped. The former method involves splicing while keeping the old web in a running state and causing the new web to follow the same speed as the old web, which has the disadvantage of often causing defects or failures in splicing. In addition, in the latter method, the old web is stored in a running layer on the festoon consisting of dancer rolls on the downstream side, and the old web is stopped in the splicing zone and spliced with the new web, which prevents splicing errors. It is characterized by almost no However, the latter prior art device has disadvantages such as an extremely complicated mechanism, increased manufacturing costs, and difficulty in maintenance and inspection.

Therefore, in view of the above-mentioned disadvantages inherent in the web splicing side 1 according to the prior art, the present applicant proposed a web splicing method and an apparatus therefor that satisfactorily solve the problems.
The patent application was completed as Japanese Patent Application No. 17477/1983.

This invention [L: In this invention, when joining the terminal end of an old web and the starting end of a new web, an adhesive means is provided at the starting end of the new web while the old web is being fed, and the joining is waited for. , the arrival of the final end of the old web is detected and the running of the web is stopped, and the old web and the waiting new web are held by the pinching means to cut the old web at a proper position, and the new web is cut by the pressing means. The new web is moved in the web feeding direction while being pressed and stroked, so that the starting end of the new web provided with the adhesive means comes onto the cut rear end surface of the old web, and adhesive splicing is performed. As mentioned above, as a joint V & structure that moves the new web in the web feeding direction while pushing it, there is an intermediate roll rotatably disposed on the trolley, and an intermediate roll that is supported by the trolley so as to be able to approach and move away from it. Two pressure rolls have been proposed that rotatably sandwich the intermediate roll when they approach each other.

By the way, the web splicing device according to the above application can splice both old and new webs quickly and reliably.

Moreover, although it has the great advantage of being able to be carried out in a state where the seam allowance is minimized, on the other hand, the following difficulties have been pointed out. That is, the joining of the new and old webs is carried out by overlapping the cut end of the old web with the starting end of the new web and then pressing and smoothing it with a pressure roll. However, when the old web is cut with a cutter, Since the web is a thin film-like material, its cut ends tend to curl up in the direction in which the cutter advances. If the cut end of the web curls up in this way, the starting end of the new web will not overlap properly, resulting in poor splicing.

The present invention has been proposed in order to satisfactorily solve the above-mentioned drawbacks, and includes a clamping means that is disposed near and apart from the web running path and clamps both the new and old webs, and a clamping means provided in the clamping means. a truck that runs parallel to the web travel path; an intermediate roll rotatably disposed on the truck; and two rollers that are supported by the truck so as to be able to move toward and away from the truck and rotatably sandwich the intermediate roll when approaching the truck. It consists of a pressure roll and an air supply pipe that faces an annular groove provided around one of the two pressure rolls and blows compressed air toward the web traveling path.

Next, regarding the web splicing device according to the present invention.

By way of example only and with reference to the accompanying drawings.

This will be explained in detail below. Although this embodiment will be described as a "packaging material web splicing device" that is suitably incorporated into a bag making, filling and packaging machine, the present invention is not limited thereto.

The chain lines indicate two rolls, a new roll and an old roll, and the old roll 18 located diagonally below continuously feeds the old web 16 toward a predetermined processing step (not shown) disposed on the downstream side.

A new roll 20 is loaded diagonally above and to the right of the old roll 18 and is waiting to be replaced with the old roll 18.

In the illustrated embodiment, the old web 16 is fed out from the old roll 18 substantially horizontally, and is changed direction by the guide roll 22 and runs vertically downward.

After passing through a splicing zone A, which will be described later, the direction is changed by two guide rolls 24 and 26 disposed below with a predetermined distance between them, and the direction is changed to, for example, a bag making mechanism (not shown) of a bag making, filling and packaging machine. is being supplied to. Immediately before entering the bag making mechanism, the old web 16 is stored in a running state for a predetermined length by a dancer roll (not shown). Further, the feeding of the old web 16 during use is provided by a pair of feeding rollers 30 and 32 disposed horizontally below a backing plate 28 of a predetermined width located perpendicularly to the splicing zone A. There is. That is, one of the feed rollers 30 is driven by a belt by a motor 34 equipped with an electromagnetic clutch, and by controlling the start and stop of this motor 34 by a command signal, the old web 16 held between the two rolls is run and stopped. It is.

In the splicing zone A, a web splicing mechanism 12 is arranged, as shown in FIG. 2 and in particular in FIG. In other words, as the old web 16 fed out from the old roll 18 wears out, the web splicing mechanism 12 combines the old web 16 with a new roll 2 that has been previously loaded into the device and kept on standby.

36 clamps are performed.

As described above and shown in FIG. 5, the rectangular frame 60 includes a pair of upper and lower plates 76 and 76 extending in the horizontal and lateral directions;
It is composed of a pair of side plates 80.degree. 80 extending in the vertical direction, and a cart 4o that rotatably supports the intermediate roll 42 is disposed on this frame 6o so as to be movable. That is, as shown in FIGS. 3 and 5, guide rails 82.82 each having a U-shaped cross section are integrally formed inside the pair of side cutouts 80.80 constituting the frame 6o. with their longitudinal openings facing each other. A truck 4o having a plurality of wheels 84 is disposed between the pair of guide rails 82.degree. 82 so as to be able to slide freely. For example, as shown in FIG. 5, the trolley 40 consists of a pair of holding members 86.86 having a predetermined shape, and the holding members 86.86 have a pair of upper and lower pivots 88.
88 are commonly inserted and supported. An axle 84 made of, for example, a bearing is rotatably supported at both ends of the pivot 88, and its position is regulated by a collar 85.
And these axles 84.84 are connected to the guide rail 8.

That is, a pneumatic cylinder 92 is pivotally attached to the lower inner surface of the upright frame loa via a pin 94, and a piston rod 96 of this cylinder 92 is rotatably connected to one end of a crank lever 98 via a pin 100. . As shown in FIG. 5, the crank levers 98 are fixed to left and right pairs of shafts 104 that are rotatably inserted into bearings 102 and 102 disposed on the upright frames 10a and 10b, respectively. There is. The other end of the crank lever 98 is shown in FIGS.
As shown in the drawings and FIG. 6, it is connected to a link plate 108 via a pin 106, and this link plate 108 is rotatably connected to the holding member 86 via another pin 110. Thus, in FIG. 2, when the pneumatic cylinder 92 is pressurized, the piston rod 96 extends from the cylinder tube to rotate the crank lever 98 clockwise about the shaft 104. This rotation of the crank lever 98 is converted into a linear motion by a link plate 108 connected to the other end, so that the holding members 86, 86 forming the truck 40 move downward along the guide rails 82, 82. It will be understood that sliding movement can be performed with a predetermined stroke.

Next, the truck 40 is provided with the pair of pressure rolls 44.4.

At the open end of 18, there is a stopper of a predetermined shape! 20 is fixed to prevent the bracket from falling off. Press rolls 44 and 46 are respectively pivotally supported on brackets 112 that are slidably inserted into each guide post 118, and intermediate rolls 4 are rotatably supported between the holding members 86 and 86.
The positional relationship between the brackets 112 and 2 is shown in FIG.
6, as shown in FIG. 5 and FIG. 7(b), the intermediate roll 42 is positioned between the two pressure rolls 44, 46 without contact, with a slight gap between them. The relationship is set up so that

Further, as is clear from FIG. 4, a plurality of annular grooves 46a are provided around the outer periphery of the pressure roll 46 at predetermined intervals in the longitudinal direction, and each of the annular grooves 46a has an air supply pipe 47 formed in a curved manner. The opening of the tube is directed toward the web travel path.

That is, a straight air supply pipe 49 is disposed parallel to the pressure roll 46, and the air supply pipe 49 is fixed to the bracket +12 via mounting plates 51 at both ends thereof. The air supply pipe 47 is connected to an air supply pipe 49.
After communicating and branching from the corresponding portions, it is curved and positioned so as to face the annular shape 1146a provided around the press roll.

The pneumatic cylinder 148 is energized to cause the piston rod +
When the cutter 50 is extended, the cutter 142 extends forward through the slit 140 formed in the contact plate 28 and cuts the old web 16.

Next, a procedure for splicing old and new webs using the web splicing apparatus according to the present invention constructed as described above will be described with particular reference to FIG. 7. First, in FIG. 1, the old web 16 is fed out from the old roll 18 by the rotation of the feeding rolls 30 and 32, and
It is assumed that the vehicle is traveling in a predetermined direction while being guided by 2,24°26. Further, it is assumed that a new roll 20 is placed in the roll exchanger groove 14 and is waiting to be replaced at the diagonally upper blade position of the old roll 18. As shown in FIG. 2, the web splicing mechanism 12 has a clamping means 38 on standby with a predetermined distance from the contact plate 28, and two pressers rotatably supported on brackets 112 and 112. It is assumed that the rolls 44, 46 are also in a standby state with a predetermined distance between them and the holding members 86, 86.

In this state, the operator manually pulls out the starting end of the new web 36 on the new roll 20, as shown in FIG. 7(a), until the register mark 212 attached to the web reaches the top of the intermediate roll 42. position it like this. Thereafter, by rotating the manual operation lever 132 counterclockwise in FIG. 2, the lever +22 rotates counterclockwise via the link plate 136, and the bracket 112, 112 is each guide post 11
Slide to the left on 8°118. As a result, the 7th
(b) As shown in the figure, a pair of upper and lower pressure rolls 44°46
The intermediate roll 42 supported by the trolley 40 is sandwiched in a non-contact manner, so that the vicinity of the starting end of the new web 36 is pinched in an S-shape by the three rolls. The new web 36 located above is cut along the longitudinal direction of the intermediate roll using a knife or the like at the part marked with the register mark 2+2, and a small amount of paper is cut from the starting end of the new web 36 to the cut part. Remove the remaining pieces. Then, as shown in FIG. 7(b2), a suitable adhesive tape 2+4 is pasted on the newly cut end of the new web 36 on the tangent n surface of the half, and the other half of the adhesive surface remains on the surface of the intermediate roll 112. When this operation is completed, the new and old webs are ready to be spliced together.

When the old web 16 wound around the old roll 18 is consumed in a processing step (not shown) and the diameter of the old roll 18 decreases, the remaining web amount detection means is activated, and a sound such as an intermittent buzzer or light is activated. 7. Send a signal to the operator to confirm whether the new roll 20 is set in the predetermined position. When the consumption of the old web 16 in the old roll 18 is further promoted and the register mark 2+2 attached a predetermined distance from the final end of the web 16 passes in front of the detection head of the register mark detection means, here, first, A first logical condition is set. Further web 16
When the final end of the web is unwound from the bobbin of the old roll 18 and passes in front of the detection head of the no-web detection means 204, a second logical condition is set. And the establishment of these two logical conditions is set as an AND condition.

The rotation of the electromagnetic clutch motor 34 is stopped, the clutch is released, and the brake is activated all at once.

Power transmission to the feed roller 30 is cut off and instantaneous stop is achieved. As a result, the feeding-out movement of the old web 16 is immediately stopped. However, as mentioned earlier, a dancer roll (not shown) is provided on the downstream side, and the old web 16 is stored therein for a predetermined length while running, so at least the time required for splicing is The continuous operation continues without affecting the processing of the web on the downstream side.

After the payout rolls 30, 32 have thus stopped.

In FIG. 2, the pneumatic cylinder 68 is pressurized and its piston rod 72 is retracted into the cylinder tube, thereby causing the crank lever 56.58 and the connecting rod 6
A 4n link mechanism consisting of 4 is driven. As a result, the clamping means 38 consisting of a frame 60 connected to the tip of each crank lever moves toward the contact plate 28, and as shown in FIG.
．． 36 is held between the backing plate 28 (only the old web 16 in the downward direction), and the slit 140 is provided in the part of the backing plate 28 located between the intermediate roll 42 and the lower pressing roll 46. 4, the cutter 142 extends forward through the slit 140 to cut the old web 16 laterally.

At this time, the cut end of the old web 16 is cut by the cutter 142.
Since it is forcibly moved in the direction of movement, that is, to the left in FIG. 7(c), it exhibits a tendency to roll up as described above. However, in the device of the present invention, compressed air is blown out and supplied via the air supply pipe 49 from the air supply pipe 47 that faces the double-circuit annular groove 46a provided around the surface press roll 46 at predetermined intervals. It has become. Therefore, the air supplied under pressure acts to press the rear end of the old web 16 cut by the cutter 142 against the contact plate 28. Therefore, the cut end of the old web 16 is laid flat on the backing plate 28 without curling up.

Cutter 142 immediately retracts after cutting the old web.

The pneumatic cylinder 92 shown in FIG. 2 is then pressurized to extend the piston rod 96 and engage the crank lever 98.
is rotated clockwise around its shaft 104. The link plates 108, 108 connected to the other end of the crank lever 98.98 are connected to the holding members 86, 86 constituting the truck 40 (see FIG. 5). 98 in the clockwise direction causes the truck 40 to travel downward in the guide rail 82 via its wheels 84. That is, as shown in FIG. 7(d), the cut end of the new web 36 is pressed by the upper pressing roll 44 with an appropriate pressing force.

Finally, as shown in FIG. 7(e), the adhesive tape 214 applied to the cut end of the new web 36 is adhered to the final cut end of the old web 16, and the new and old webs 16.3'6 are joined together. The alignment is completed (Fig. 7(el)).

After the pressure roll 44 strongly presses the adhesive tape 214 and adheres it to the final cut end of the old web [6], the pneumatic clamp 68 is reversely biased, and the four-bar linkage mechanism is also reversely biased. Operate. Therefore, the clamping means 38 constituted by the frame 60 is separated from the contact plate 28 and releases the clamp on the new and old front webs 16.36. Further, the motor 34 also starts to rotate again, and the feeding roll 3
Web feeding by 0°32 is resumed. Also the 7th
(g) As shown in the figure, the pneumatic clamp 92 is reversely biased and the crank levers 98, 9B are rotated counterclockwise, thereby returning the truck 40 to the original position shown in FIG. The web splicing process is completed. In this state, the two pressure rolls 44 and 46 are the intermediate roll 42.
This is a manual operation lever +
By operating 32, it is returned to the initial position as shown in FIG.

As described above, the web splicing mechanism 12 completes splicing of the old and new webs, and the old web 16 is attached to the new roll 20.
There will be a smooth transition to the new web wound on the web, and the unwinding will continue.

Note that in the device according to the present invention, #! A roll 30°3
We set two conditions for stopping the rotation in step 2: detection of a register mark and detection of the final edge of the film.
In addition, without providing a register mark, the rotation of the motor 34 may be stopped on the condition that a certain period of time has elapsed after the final end of the web is detected. The feeding speed and other splicing allowances can be arbitrarily set in consideration of conditions such as the first. Furthermore, in this embodiment, a method was adopted in which the feeding of the old web was stopped when splicing the old and new webs together, but the web may be connected in a continuous feeding state without stopping the web. .

As explained in detail above, according to the web splicing device according to the present invention, there is provided a clamping means that is disposed so as to be close to and separated from the web traveling path and clamps the old and new webs, and a clamping means provided in the clamping means. A trolley that runs parallel to the web travel path;
An intermediate roll rotatably disposed on the truck, and two press rolls supported by the truck so as to be able to approach and separate from each other, and rotatably sandwich the intermediate roll when approaching.

Since it is configured with two feed pipes that face an annular groove provided around one of the two pressure rolls and blow compressed air toward the web traveling path, when cutting the old web with a cutter, the By blowing compressed air onto the web traveling path through the air supply pipe, it is possible to effectively prevent the cut end of the web from curling up in the direction in which the cutter moves. In addition, the web splicing, which conventionally required complicated equipment and processes, can be performed quickly and quickly, and the splicing cost can be minimized to save on the web, resulting in many beneficial effects. It is.
