Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for feeding a sheet from a paper roll to a downstream side line such as a printing line and feeding a paper from the next paper roll to a paper from a paper roll with a small remaining amount. The present invention relates to a splicer for adhering and joining paper sheets.

[0002]

2. Description of the Related Art Conventionally, as one of the above-mentioned splicers, a so-called zero speed type splicer as shown in FIG. 19 has been used. This splicer 10
In No. 0, two paper roll holders 101 that rotatably hold the paper roll are attached to both ends of the rotary arm 103, and the first paper roll R1 to the paper P1 are two pressure bonding units 105 (in the splicing head 104). Figure 2
0 (a)), while the second paper roll R2 stands by for the next feeding.

Then, when the remaining amount of the first paper roll R1 becomes small, the rotation of the first paper roll R1 is stopped, and as shown in FIG. 20 (a), the corresponding paper pressure member 106 sucks and holds the paper P1, and the cutter 107 in that state. Then, this is cut before the crimping member 106. Then, the other crimp member 106
Is rotated and moved so that the end portion of the paper P2 from the second paper roll R2 suctioned and held by the paper is opposed to the paper P1 from the first paper roll R1, and the paper P1 and P2 are sandwiched between the two crimp members 106. The joining is completed by press-bonding the two via the double-sided adhesive tape T. Here, the first roll paper R1
In order to absorb the difference with the supply speed of the paper P1 in the downstream side while the rotation of the
As shown in, a dancer roll mechanism 110 is arranged on the downstream side of the splicer 100.

On the other hand, as a splicer different from the one described above, a so-called speed match type splicer is also used. This is, while continuing the feeding of the paper from the first web at the same speed as the supply speed in the downstream process,
The second paper roll on standby is rotated at a speed substantially equal to this speed, and the papers from both paper rolls are spliced together via a double-sided adhesive tape or the like by a pressure bonding head or the like.

[0005]

Among the splicers described above, the zero-speed type splicer has the following drawbacks. (1) Since the rotation of the paper roll being fed out must be stopped when the paper is spliced, the difference in the paper supply speed between the line side and the splicer side is large, and the dancer roll mechanism that absorbs this is also large. However, there is a problem that the device is enlarged. (2) As shown in FIG. 20 (a), the second roll paper R 2 is located at the end of the paper P 2 and is sucked by the pressure-bonding member 106.
By holding and holding the double-sided pressure-sensitive adhesive tape T thereon, a standby state for joining is brought about, but all of these must be done manually, which requires manpower. (3) As shown in FIG. 21, on the preceding sheet P1 after cutting and pressure bonding, the residual portion Q protruding from the double-sided adhesive tape T to the upstream side corresponds to the distance between the cutter 107 and the pressure bonding member 106. Is always formed. Such a residual portion Q may cause a catch or a paper jam in the downstream line.

On the other hand, in the speed match type splicer, since it is necessary to join the sheets while continuing the feeding of the sheets at a high speed almost equal to the feeding speed of the downstream side line, an error occurs in the cutting position of the preceding sheet. Cheap. As a result, the residual portion protruding from the double-sided adhesive tape to the upstream side becomes extremely long, or conversely, it is cut on the downstream side from the double-sided adhesive tape, which easily causes troubles such as paper splicing failure. is there.

The object of the present invention is to eliminate the need to stop the rotation of the paper rolls at the time of splicing the papers, facilitate the automation of the work of mounting the paper rolls, and further, to the above-mentioned protrusion on the preceding paper after cutting and pressure bonding. An object of the present invention is to provide a splicer that can reduce the occurrence of parts.

[0008]

Means for Solving the Problems and Actions / Effects According to the present invention, the paper is continuously fed to a lower process such as printing while feeding the paper from a winding paper in which a paper is rolled around a core material. In the paper supply device, the present invention relates to a splicer for adhering and splicing the paper from the next paper roll to the paper from the paper roll that has run low, and is characterized by being configured with the following requirements: To do. First roll paper holder: Holds the roll paper rotatably for feeding the paper. Second paper roll holder: Holds the next paper roll in a rotatable manner. Feeding speed adjusting mechanism: When the sheets are joined, the feeding speed of the rolled paper from the first rolled paper holding unit is adjusted to a predetermined value that is smaller than the feeding speed of the paper at the exit side of the paper feeding device. Rotational drive unit: The winding paper held in the second winding paper holding unit is rotationally driven at a speed corresponding to the feeding speed of the winding paper from the first winding paper holding unit side adjusted to the predetermined value. Adhesion mechanism: The paper fed from the side of the first paper roll holder is adhered to the paper roll held by the second paper roll holder.

In the above-mentioned splicer, the feeding speed of the roll of paper from the first roll holder is adjusted to a predetermined value which is smaller than the sheet feeding speed at the exit side of the sheet feeder by the feeding speed adjusting mechanism. The paper rolls held by the second paper roll holder are rotationally driven at a speed corresponding thereto, and in this state, the papers of the two paper rolls are bonded by the bonding mechanism. As a result, the difference in the paper supply speed between the line side and the splicer side becomes smaller than that of the conventional zero-speed type splicer, so that the device (dancer roll mechanism, etc.) for absorbing this can be downsized. . On the other hand, compared to the speed match type splicer, the feeding speed of the paper at the time of splicing the paper is lower, so it is less likely that an error will occur in the cutting position of the preceding side of the paper, the remaining portion will become longer or splicing will fail. Trouble such as doing is hard to occur.

Here, the feeding speed of the web from the side of the first paper holding portion is 5 to 50 m / m by the feeding speed adjusting mechanism.
It is desirable to adjust within the range of minutes. Delivery speed is 5m /
If it is less than a minute, the superiority to the above-mentioned zero speed type splicer is lost. On the other hand, if it exceeds 50 m / min, an error is likely to occur in the cutting position of the paper, and the same problem as in the speed match type splicer occurs.

Next, in the above-mentioned splicer, with the double-sided pressure-sensitive adhesive tape attached to the end portion of the rolled-up paper, the paper roll is held by the second paper roll holder, and the adhesive mechanism is attached. The double-sided pressure-sensitive adhesive tape can be configured to be bonded by pressing a sheet of paper fed from the side of the first paper roll holder. In this way, if the paper being fed is pressed against the double-sided adhesive tape attached to the end of the rolled paper, splicing is completed, so there is no need to cue the next roll of paper. It is also easy to automate the mounting of the paper roll on the splicer.

As an apparatus configuration for automatically mounting a roll of paper onto a splicer, a roll of paper storage for holding the roll of paper on standby with the double-sided adhesive tape attached to the end of the roll of paper, It is possible to exemplify a mode including a paper roll supply unit that supplies the paper roll that has been put on standby to the second paper roll holding unit.

The first and second paper roll holders may be provided with holding chucks for rotatably holding the paper roll at both ends of the core material. This makes it easier to attach the paper roll to the paper roll holder. In this case, the respective holding chucks of the first and second paper roll holders are attached to the rotary holders arranged on both sides of the held paper roll, and the axes of the respective webs held are substantially parallel to the rotation axis of the rotary holder. It can be mounted symmetrically with respect to the axis of rotation. Then, the roll of paper is mounted on the second roll holder at the roll mounting position set below the rotation axis of the rotary holder, and the roll is rotated about 180 ° together with the rotary holder to mount the roll with respect to the rotation axis. It is possible to move to a bonding position which is set to a position symmetrical to the position and to make the paper roll held by itself stand by for bonding with the paper fed out from the first paper roll holding unit side.

With the above-mentioned structure, the web can be always mounted under the splicer.
For example, by configuring the above-mentioned paper roll supply unit by a conveyor or the like, there is an advantage that the supply / mounting of the paper roll at the mounting position can be automated by a relatively simple mechanism. Further, since the mounting position and the adhering position are set symmetrically with respect to the rotation axis of the rotary holder, the rotation direction of the rotary holder for mutually moving the paper holder between the two positions is one direction. Therefore, the rotation mechanism of the rotation holder can be simplified.

On the other hand, the axes of the webs held by the respective holding chucks of the first and second web holders are substantially the same as the rotation axes of the rotary holders arranged on both sides of the held web. The rotary holders may be mounted so as to be parallel to each other, and each of the rotary holders may be rotatably supported by a cantilevered rotary shaft that gives the above-mentioned rotary axis on the side not facing the web. According to this structure, the rotation shaft can be eliminated from between the both rotary holders, and the first and second paper roll holders can be provided closer to each other, and therefore the rotation of both paper roll holders can be prevented. The radius is reduced, and the splicer can be downsized.

The operation of the splicer 1 will be described below. In FIG. 6, in the state where the first paper roll holder 3 is located at the feeding position U, the paper rolls held by the first paper roll holder 3 (hereinafter,
Paper P2 is supplied from R2 (referred to as old roll paper) to the downstream side via the dancer roll mechanism 18 and the tension adjusting mechanism 22. On the other hand, the second paper roll holder 4 waits for a new paper roll (hereinafter referred to as a new paper roll) R1 to be mounted. Here, for example, as shown in FIG. 3, on the new roll paper R1, a double-sided adhesive tape T is attached to the outer surface of the end portion of the roll paper P in the width direction, and in this state, As shown in FIG. 6, it is mounted on the second paper roll holder 4 located at the mounting position L. Here, on the front side of the mounting position L, a conveyor 37 that is intermittently driven in a state where the new paper roll R1 is placed is provided.
Thus, the new paper roll R1 can be automatically supplied to the second paper roll holder 4. In this case, the conveyor 37 constitutes a roll paper storage unit and a roll paper supply unit. In addition, a lifter 38 for raising and lowering the new paper roll R1
May be provided directly below the mounting position L. In this case, when the new paper roll R1 is transferred from the conveyor 37 to the lifter 38,
The lifter 38 can be configured to raise the new web R1 to the mounting position, lower it again when the mounting of the new web R1 is completed, and wait for receipt of the next new web R1.

FIG. 7 shows a state in which the new paper roll R1 is mounted on the second paper roll holder 4. On the other hand, the old paper roll R2 on the side of the first paper roll holder 3 has its remaining amount decreased as the paper P2 is fed out. Then, when the remaining amount becomes equal to or less than a predetermined value, the rotary arm 2 is set to 1 as shown in FIG.
The first and second paper roll holders 3 and 4 are rotated by 80 °.
Swap the positional relationship of. This operation is performed by the drive motor 15
(Fig. 2), the drive command can be given manually while visually checking the remaining amount of paper, or by detecting the remaining amount of paper by a separately provided remaining paper amount sensor Z, Either may be performed automatically based on the detected remaining amount value. The following is the process of joining the new paper roll R1 to the old paper roll R2, which is shown in FIG.
It is controlled based on a control program 54a stored in the ROM 54 of the control unit 50 shown in FIG.

FIG. 13 shows the flow of the processing.
That is, in S1, based on the input from the input unit 62 or the like (or the detection result by the above-described sheet remaining amount sensor),
A splice command signal is issued to the CPU 52 from a command signal generator (not shown). In S2, CPU52
In response to this, the air brake 16 on the old paper roll R2 side (in this case, the first paper roll holder 3 side) is activated. Then, in S3, based on the rotation speed detected by the corresponding rotation sensor 17, the feeding speed of the paper P2 from the old roll paper R2 is set (splice speed: for example, input from the input unit 62, and stored in the splice speed memory 53a of the RAM 53). (Stored) is determined. The splicing speed is set in the range of 5 to 50 m / min, for example. Here, the feeding speed of the paper from the old web R2 is determined by the paper feeding device 70 (that is, the dancer roll mechanism 1).
8) It becomes smaller than the sheet feeding speed on the exit side. In response to this, in the dancer roll mechanism 18, the upper roll group 20 descends to reduce the length of the reservoir V, and the above speed difference is absorbed.

When the feeding speed of the paper P2 reaches the splice speed, the operation of the air brake 16 on the old winding paper R2 side is released and the acceleration mechanism 6 is operated in S5.
The new paper roll R1 is rotated at a predetermined speed (controlled based on the rotation speed detected by the corresponding rotation sensor 17). At this stage, the splicing head 7
Is the arm drive cylinder 29, as shown in FIG.
By the operation of (FIG. 1 etc.), the new paper roll R1 is on standby in a state in which it has moved to a position close to the outer peripheral surface thereof. Next, at S6, as shown in FIG.
When the tip of the double-sided adhesive tape T attached to 1 is detected by a tape detection sensor 40 such as a reflection type sensor arranged at a predetermined position near the new paper roll R1, the nip roll drive cylinder 32 operates. . As a result, as shown in FIG. 10A, the nip roll 31 presses the paper P2 from the old paper roll R2 toward the double-sided adhesive tape T attached to the new paper roll R1, and the papers P1 and P2 from both paper rolls are pressed.
And are pressure-bonded and joined via the double-sided adhesive tape T. At the same time, detection of pulses from the rotation sensor 17 on the side of the new paper roll R1 is started, and the count number is accumulated in the pulse counter memory 53c of the RAM 53 (S7).

Then, based on the counted number and the width of the double-sided adhesive tape T in the paper feeding direction, it is judged whether or not the rear end of the double-sided adhesive tape T coincides with the position of the cutter 33, and they coincide with each other. Then, the cutter driving cylinder 34 is operated, and the cutter P is used as the cutting position to cut the paper P2.
To cut (S8, S9). On the other hand, the pulse count is further continued, and the double-sided adhesive tape T
If it is determined that the trailing edge has passed the nip roll 31,
As shown in FIG. 10B, the nip roll 31 is retracted at the nip end position to complete the joining of the sheets (S10, S11). Further, in S12, the arm 27 is turned in the opposite direction to the above to retract the splicing head 7. If this happens,
As shown in, the rotation of the new web R1 after splicing is accelerated by the acceleration mechanism 6 (S13). Then, when the rotation speed reaches a steady speed (stored in the steady speed memory 53b of the RAM 53) set corresponding to the paper feed speed on the exit side of the dancer roll mechanism 18, the acceleration is stopped and accelerated. The mechanism 6 is retracted (S15). Then, the old paper roll R2 after the paper is cut is removed from the first paper roll holder 3, and a new paper roll is mounted in its place, and the same processing is repeated thereafter.

In the above embodiment, the position of the double-sided adhesive tape T was detected by the tape detection sensor 40. However, the double-sided adhesive tape T is moved to a predetermined preparation position for pressing by the nip roll 31. May be manually aligned. In this case, the tape detection sensor 40 can be omitted.

Further, each of the paper roll holders 3 and 4 is shown in FIG.
It can also be configured as shown in. In this structure, the chuck plates 9 are provided on both sides of the web R to be held.

Here, as shown in FIG. 15, one of the chuck plates 9 is driven to approach / separate for attachment / detachment of the paper roll R by a cylinder 38 fixed to a frame 39 connecting the both holders 10, The other one has a screw shaft 42 that is screwed into a screw hole provided through the motor shaft 4 that is also fixed to the frame 39.
By rotating at 1, the position can be adjusted according to the paper width of the web R.

On the other hand, in the splicing head 7, as shown in FIG. 16, for example, a guide protrusion or the like provided on the main body of the splicing head 7 is moved within the groove 45 formed in the frame 5 so that the web R is wound. It is also possible to adopt a configuration in which they approach and separate linearly with respect to.
In this configuration, the dancer roll mechanism 18 is provided above the frame 5 so as to form the reservoir V of the paper P in the horizontal direction, and the tension adjusting mechanism 22 is provided below the dancer roll mechanism 18. It is arranged.
