(Base paper edge automatic processing equipment)
Here, the base paper edge automatic processing apparatus will be described. As the paper splicing device 10 as a part of the base paper edge automatic processing device, a known one can be used, and a new paper to be newly supplied to the old base paper (old web) currently supplied by the paper splicing device 10. The base paper (new web) can be spliced together.

  Here, as shown in FIG. 2, the paper splicing device 10 includes guide rolls 13 and 14, a pair of crimping bars 15 and a knife 16, and an electromagnetic brake built in the guide roll 14 at the time of paper splicing. A double-sided tape preliminarily pasted to the front end of the new web after the web running by a mechanism (not shown) is stopped, the old web and the new web are crimped by the crimping bar 15 with the web running stopped. The old and new webs are joined via the knife 16 and only the old web upstream of the joined portion is cut by the knife 16. Thereafter, a new web spliced is supplied by releasing the brake of the guide roll. The crimping bar 15 is provided with a suction mechanism (not shown) so that the new web waiting to be spliced is held in a state of being sucked by the crimping bar 15.

A holding member (holding means) 41, a guide member 42, and a new web guide member 43 are provided on the upstream side of the paper splicing device 10 in the base paper conveyance direction.
The holding member 41 is provided with an air suction port (not shown) as suction means for applying a suction force to the old base paper roll 9, and the web is held by applying the suction force from the air suction port. The member 41 can be sucked and held.

In addition, the holding member 41 is provided with an adhesive injection device (adhesive application device) (not shown) that injects an adhesive (paste) onto the held old web and applies an adhesive to the end of the old web. ing.
Instead of the suction means provided in the holding member 41, the holding member 41 and the guide member 42 are arranged at a relative position having a predetermined distance from each other so that the old web being fed can pass therethrough. It may be configured to be able to be displaced to a relative position where the old web is gripped together, and may be configured as an end gripping mechanism that grips or releases the old web by the holding member 41 and the guide member 42.

  The holding member 41 can be displaced toward the base paper roll at the base paper supply position by a transfer rail (holding means displacement mechanism) (not shown). Then, by driving a base paper roll driving mechanism, which will be described later, together with the held old web, it is displaced toward the base paper roll side, and when it is displaced to a predetermined position, glue (adhesion) is directed toward the end of the old web by the adhesive jetting device. And the holding of the old web by the suction means is released.

  In addition, when the end portion of the old web is wound around the old base paper roll by adhesion with glue, the old web wound is prevented from being unnecessarily unwound from the base paper roll. When used as an adhesive, it is necessary to peel off the web so that the web can be easily fed out again. Therefore, the viscosity of the glue sprayed from the adhesive spraying device is set to take these into consideration.

The new web guide member 43 is configured to hold the new web fed from the new base paper roll 9 with the guide member 42 at the time of paper joining standby or during paper joining. Is configured to release.
Further, an old base paper roll driving device (winding mechanism) (not shown) that automatically rotates and drives the old base paper roll at the base paper supply position is provided. The old base paper roll drive mechanism is controlled by a control device (not shown) so as to drive the web in the direction of winding the old base paper roll when the old web is cut by the knife 16.

Since the base paper edge automatic processing apparatus according to the embodiment of the present invention is configured in this manner, the following operations and effects are described with reference to FIGS. 5 and 6.
First, in the state shown in FIGS. 5A and 6A, the base paper roll 9A is gripped by the upper swing arms 5A and 5B at the base paper supply position above the carry-out side mounting table 4, and from the base paper roll 9A. The base paper (web) W is fed out, and the fed-out web W is conveyed via the paper splicing device 10 to each subsequent device of the corrugating machine.

On the other hand, the base paper roll 9B to be used next to the base paper roll 9A is gripped by the lower swing arms 6A and 6B at the paper splicing position above the carry-in placement table 3, and the web W is fed from the base paper roll 9B to the splicing device 10. The base paper roll 9 </ b> B waits at the paper splicing position until paper splicing is performed by the paper splicing device 10.
At this time, the base paper roll 9C to be used next to the base paper roll 9B is carried into the belt conveyor 2B on the most downstream side of the carry-in rail 2, and the base paper roll 9C waits on the belt conveyor 2B.

  When the base paper supplied to the corrugating machine is changed (order change), the web W of the base paper roll 9A and the web W of the base paper roll 9B are bonded together by the paper splicing device 10, and the web W of the base paper roll 9A is Cutting and paper splicing are performed. The web W of the next base paper roll 9B is spliced to the web W of the base paper roll 9A, which is the old base paper roll, and the base paper roll 9B has been changed in size, paper quality, etc. from the base paper of the base paper roll 9A. The base paper is continuously supplied to the corrugating machine without interruption (paper splicing step).

The state shown in FIGS. 5 (B) and 6 (B) is a state following FIGS. 5 (A) and 6 (A), and here, the old base paper roll 9A that has been used is carried out (No. 1). 2 loading table unloading step, old base paper roll unloading step).
4 or 6B, the support floor 4A of the unloading stage 4 is moved below the old base paper roll 9A by the old base paper roll lifter 4B. It rises to a position where it abuts or substantially abuts (closest to the nearest).

Here, the automatic processing of the web edge portion by the base paper edge automatic processing device will be described in more detail. At the time of paper joining, the web of the new base paper roll 9B and the web of the old base paper roll 9A are bonded together in the paper splicing device 10, and the web of the old base paper roll 9A is cut.
When the web of the old base paper roll 9A (old web) is cut, a suction force is applied to the air suction port of the holding member 41, and the old web is sucked and held by the holding member 41 without falling. Thereafter, when the old base paper roll driving device is driven, the old base paper roll 9A rotates counterclockwise in FIG. 6B, and the old web is wound around the old base paper roll 9A.

  At this time, the holding member 41 moves to the old base paper roll 9A side on the transfer rail while giving an appropriate tension to the old web in response to the old web being wound. And when the holding member 41 moves on the transfer rail to a predetermined position, the holding member 41 releases the holding of the old web and the adhesive is sprayed on the vicinity of the old web by the adhesive jetting device of the holding member 41, The old web is released from the holding member 41 and wound around the old base paper roll 9A, and is bonded to the old base paper roll 9A at the end of the old web on which the glue is jetted. This completes the automatic processing operation for the edge of the base paper.

  When the paper splicing operation by the paper splicing device 10 and the automatic processing of the end of the base paper are completed, the upper swing arms 5A and 5B are moved along the upper fulcrum shaft 20 in the web width direction of the base paper roll as shown in FIG. Each of them slides outward to release the old base paper roll 9A. The old base paper roll 9A released from gripping by the upper swing arms 5A and 5B is placed on the support floor 4A of the carry-out side placement table 4.

When the old base paper roll 9A is placed on the support floor 4A, the support floor 4A is gradually lowered to a height substantially equal to the carry-out rail 8 by the old base paper roll lifter 4B, and the support floor 4A is lowered by the inclination angle providing mechanism 4C. And an inclination angle is given so that each bridge member 12 may become low toward the carrying-out rail 8 from the carrying-out side mounting base 4. FIG.
As a result, the old base paper roll 9A placed on the support floor 4A is carried out from the base paper supply position to the lower carry-out side placement stage 4 (second placement stage carry-out step). Thereafter, due to the inclination of the support floor 4A and the bridge member 12, the support floor 4A rolls to the carry-out rail 8 via the bridge member 12, and the old base paper roll 9A is carried to the carry-out rail 8, and each belt of the carry-out rail 8 is moved. It is carried out to the old base paper roll storage place (not shown) by the conveyors 8A and 8B (old base paper roll carry-out step).

The state shown in FIGS. 5C and 6C is a state following FIG. 5B and FIG. 6B. Here, after the end of paper splicing, the base paper roll 9B in the base paper supply state is the base paper. While being transferred to the supply position, the next base paper roll 9C of the base paper roll 9B is carried into the carry-in side placement table 3 (supply position transfer step, first placement table carry-in step).
More specifically, as shown in FIGS. 5C and 6C, the lower swing arms 6A and 6B swing clockwise in FIG. 6C while holding the base paper roll 9B in the base paper supply state. The base paper roll 9B is moved from the paper splicing position to the base paper supply position (supply position transfer step). Further, at this time, the upper swing arms 5A and 5B are in a position where the gripping of the base paper roll is released and expanded in the web width direction, but the upper swing arms 5A and 5B come and go with the lower swing arms 6A and 6B. In FIG. 6, it swings clockwise and moves from the arm angle corresponding to the base paper supply position to the arm angle corresponding to the paper splicing position.

  On the other hand, when the base paper roll 9 </ b> B is transferred from the paper splicing position to the base paper supply position, the belt conveyor 2 </ b> B and the bridge member 11 are lowered toward the carry-in side placement table 3 by the inclination angle providing mechanism 2 </ b> C of the carry-in rail 2. The base paper roll 9C which is inclined and is placed on the belt conveyor 2B rolls along the inclination and is carried from the belt conveyor 2B to the loading-side loading table 3 via the bridge member 11 (first loading table). Loading step). When the base paper roll 9C is carried into the carry-in placement table 3, the restricting portions 3B and 3C stand up, thereby preventing the base paper roll 9C from falling off the support floor 3A.

The state shown in FIG. 5D and FIG. 6D is a state following FIG. 5C and FIG. 6C. Here, the base paper is supplied by the base paper roll 9B at the base paper supply position. The next base paper roll 9C is carried into the paper splicing position and waits until the paper splicing.
More specifically, as shown in FIGS. 5D and 6D, the support base 3A on which the new base paper roll 9C is placed is gradually raised by the new base paper roll lifter 3D of the carry-in side placement table 3 so that the new base paper is raised. The roll 9C is transferred to the paper splicing position or the vicinity thereof.

  Then, at or near the paper splicing position, the upper swing arms 5A and 5B slide and move inward in the web width direction, and the insertion portions 23A and 23B are inserted into the shaft core of the new raw paper roll 9C, The new base paper roll 9C is held by the swing arms 5A and 5B. Thereafter, the support floor 3 </ b> A of the loading-side mounting table 3 is lowered by the new base paper roll lifter 3 </ b> D to substantially the same height as the belt conveyor of the loading rail 2.

After the states of FIGS. 5D and 6D, only the positional relationship between the upper and lower swing arms 5 and 6 is changed from the states of FIGS. 5A and 6A described above. FIG. 5A to FIG. 5D and FIG. 6A to FIG. 6D are performed after only the positional relationship between the upper and lower swing arms 5 and 6 has been changed. Return to the state of 5 (A) and FIG. 6 (A).
As described above, according to the base paper edge automatic processing apparatus and the base paper edge automatic processing method according to the present embodiment, the web edge processing of the old base paper roll that has finished supplying the base paper after the end of paper splicing is automatically performed. Therefore, it is not necessary for the operator to manually perform the edge processing of the web, and it is possible to reduce the operator's work load related to the edge processing of the web, and to reduce the work time required for the edge processing. Time can be shortened.

  Further, since the holding member 41 is displaced toward the old base paper roll while holding the old web in accordance with the winding of the old web by the old base paper roll driving device, the old web is being wound around the old base paper roll. It is possible to prevent the web from falling, and it is possible to prevent inconveniences such as the fallen web being soiled by dust on the floor. Further, while the old web is wound around the old base paper roll, an appropriate tension can be applied to the old web by the holding member 41 and the driving force of the old base paper roll driving device, and the old web is slackened. Inconveniences such as wrinkling of the old web during winding can be prevented.

  In this embodiment, the conveyance line for carrying in and carrying out the base paper roll 9 branches or merges in the order of the carry-in rail 2, the carry-in side placement table 3, the base paper roll transfer mechanism 7, the carry-out side placement table 4, and the carry-out rail 8. Since there is no overlap, the transport paths of the base paper rolls do not overlap, and unnecessary waiting time such as the other base paper roll is in a standby state while one base paper roll is transported in the overlapping section of the path, etc. Can be prevented, the working efficiency in replacing the base paper roll can be improved, and the cycle time required for replacing the base paper roll can be shortened.

  Also, since the base paper roll transport directions of the carry-in rail 2 and the carry-out rail 8 are substantially parallel and in the same direction, a new base paper roll base before use and an old base paper roll base after use are used. The corrugating machine or the base paper roll exchanging device can be disposed at different positions, and inconveniences such as mixing of the new base paper roll and the old base paper roll in the stock yard can be prevented.

  Further, the upper and lower swing arms 5 and 6 as the roll support device (roll support mechanism) do not interfere with the trajectory of the other swing arm by the slide mechanism (retracting structure) when the swing arms 5 and 6 themselves do not hold the base paper roll 9. Thus, the upper and lower swing arms 5 and 6 can cross each other without interfering with each other, so that the base paper roll 9 is moved from the splicing position to the base paper supply position. Simultaneously with the transfer, on the other hand, an arm for gripping the next base paper roll can be prepared from the base paper supply position to the paper splicing position.

  Furthermore, since the upper fulcrum shaft 20 that is the fulcrum shaft of the upper swing arm 5 and the lower fulcrum shaft 21 that is the fulcrum shaft of the lower swing arm 6 are arranged side by side in a substantially vertical direction, the space in the height direction is effectively used. Utilization can save space for the apparatus.

[Others]
Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention.
For example, in the above-described embodiment, the corrugating machine for producing corrugated cardboard sheets has been described as an example of the paper processing apparatus, but the paper processing apparatus of the present invention is not limited to the corrugating machine, and uses continuous paper such as a rotary printing press. It can be widely applied to printing presses and other papermaking machines.

  In the above-described embodiment, since the base paper roll exchanging apparatus in which the paper splicing position is set to only one place has been described as an example, the paper splicing apparatus is provided in only one place. In a base paper roll exchanging device that alternately supplies base paper from the paper splicing position, two paper splicing devices may be set corresponding to the paper splicing positions. In this case, the base paper edge automatic processing device including the holding member, the adhesive jetting device, the old base paper roll driving device and the like may be installed at two locations corresponding to the paper splicing device.
