Description

  The present invention relates to a roll paper splicing unit discharging apparatus suitable for removing a splicing part of roll paper such as liner paper.

In the production process of roll paper such as liner paper, the produced roll paper is once wound around a large roll jumbo roll, then unwound from the jumbo roll and divided into a desired width by a slitter. It can be rolled into multiple log rolls. As a result, when the roll paper of a desired length is rewound to these log rolls, when each of these log rolls is replaced with a new one, the roll paper is similarly unwound from the jumbo roll, It is rewound into a plurality of new log rolls while being divided into a desired width. Then, the paper ends of the log rolls that have been wound are adhered to the log rolls by a tape applicator.
As described above, the roll paper unwound from the jumbo roll is repeatedly rewound into a large number of small log rolls while being divided into desired widths and lengths.

  By the way, when the remaining jumbo roll is low, a new jumbo roll paper end is joined to the paper end of the remaining jumbo roll, and this splicing process is generally performed at intervals of 40 minutes per day. It has been performed about 30 times. As a document related to the paper splicing, there is Patent Document 1 that discloses a method of splicing a web for printing to be fed to a rotary press.

  For this reason, at the time of rewinding from the jumbo roll to the log roll, the paper splicing portion is wound around all the log rolls that take up the paper roll divided in the width direction, and the paper splicing portion is included. Log rolls cannot be shipped as products.

  By the way, the log roll containing the paper splicing section cuts the roll paper within 5 m when it is confirmed that the paper splicing section has been wound on the log roll when rewinding from the jumbo roll to the log roll. Therefore, the paper splicing portion is included within a range of 5 m from the cut portion.

  Therefore, all log rolls in which the same paper splicing portion is divided and wound up are discharged out of the production line and unwound by an operator about 5 m until the paper splicing portion comes out. After cutting the joint, the paper end of the cut log roll was adhered to the log roll with an adhesive and returned to the production line.

  In addition, the cut roll paper was piled up on a processing space (5 m × 7 m) provided on the passage, and an operator carried it to the disposal site every time a paper splicing process was performed.

  However, since the roll width of this small roll is different depending on the application and the maximum width is 7 m, it is not easy to cut out the paper spliced portion by hand.

  In addition, manual paper cutting is performed at 40-minute intervals, and this operation is repeated 30 times a day. Therefore, if the worker temporarily leaves the work site for a break, be sure to It was necessary to secure replacement personnel, which caused labor costs to increase.

  Furthermore, since it is necessary for the operator to provide a processing space (5 m × 7 m) on the passage in order to perform the cutting operation of the paper splicing portion, it is necessary to secure an extra space in the site.

In addition, as an apparatus etc. which removes the defective part of a roll base paper, as shown in patent document 2, the winding means which winds up the roll base paper unwound from the unwinding means of this roll base paper, and this unwinding means And a defective portion removing means disposed between the unwinding means and the winding means are known.
However, even if such an apparatus is used, the paper end of the roll paper cannot be automatically unwound from the log roll installed in the unwinding means. The above-mentioned excision work of the paper splicing portion that removes the paper splicing portion by successively rewinding within the range of 5 m from the end of the paper of the log roll thus obtained cannot be reduced or improved in efficiency.

  Next, the operation of the roll paper joint discharge device will be described with reference to FIGS.

First, as shown in FIG. 2, a plurality of log rolls 1 including a paper splicing portion are simultaneously rotated clockwise by a driving device 2, and are attached to the tip of the suction / lifting device 3 adjacent to the log roll 1. The end of the roll paper is detected by the ultrasonic sensor 3b (paper end detection sensor 3b) provided.
Then, from the position where the edge of the paper is detected by the ultrasonic sensor 3b, the plurality of log rolls 1 are rotated by a predetermined dimension in the counterclockwise direction by the driving device 2 and positioned.

  Next, the suction head 3a provided at the tip of the suction / lifting device 3 sucks the vicinity of the paper edge of the roll paper, and then rotates clockwise around the support shaft 3c until the paper edge becomes horizontal by a drive motor (not shown). Rotate in the direction and move up to a position where the roll paper comes into contact with the upper roller 4a of the drawing roller 4 by the elevating cylinder 3d.

In parallel with this, as shown in FIG. 3, the lower roller 4b of the drawing roller 4 is brought into contact with the roll paper by rotating it counterclockwise around the support shaft 4c with a drive motor (not shown).
Then, the roll paper is sandwiched between the upper roller 4a and the lower roller 4b of the drawing roller 4, and the upper roller 4a is rotated in the clockwise direction, whereby the roll paper is drawn between the upper and lower rollers 4a and 4b.

Then, the paper end of the roll paper fed by the optical sensor 5 (paper end detection sensor 5) shown in FIG. 4 is detected, and the driving device 2 and the upper roller 4a are stopped.
Next, after the elevating cylinder 9a is lowered, the traveling rail 9b is moved in the horizontal direction, whereby a double-sided tape (adhesive) is applied to the upper surface of the roll paper by the tape applicator 9 (adhesive device 9).
Thereafter, the elevating cylinder 9a moves up and the traveling rail 9b moves in the horizontal direction, whereby the tape applicator 9 (adhesive device 9) returns to the origin position.

  At the same time, each roll paper having double-sided tape attached to the upper surface of the paper edge is attached to the upper surface of the paper edge as shown in FIG. 5 by driving the driving device 2, the upper roller 4a, and the driving drum 7. The double-sided tape adhered to the core 6a is wound around the core 6a while preventing wrinkles and drooping by the pressing roller 6c that can rotate around the support shaft 6e.

Next, after winding the 5 m range including the paper splicing portion around the core 6a, the driving device 2, the upper roller 4a, and the driving drum 7 are stopped.
Then, after the elevating cylinder 9a is lowered, the traveling rail 9b is moved in the horizontal direction, whereby a double-sided tape (adhesive) is attached to the upper surface of the roll paper by the tape applicator 9 (adhesive device 9).
Thereafter, the elevating cylinder 9a moves up and the traveling rail 9b moves in the horizontal direction, whereby the tape applicator 9 (adhesion device 9) returns to the origin position.

Next, as shown in FIG. 6, after the double-sided tape is affixed to the upper surface of the roll paper, the driving device 2, the upper roller 4a, and the driving drum 7 are driven to wind up the roll paper and affix it to the upper surface of the roll paper. When the double-sided tape passes under the cutter 8, the driving device 2, the upper roller 4a, and the driving drum 7 are stopped, so that the winding is temporarily stopped. After the lifting cylinder 8a is lowered, the traveling rail 9b is horizontal. The cutter 8 cuts a plurality of roll papers by moving in the direction.
And the raising / lowering cylinder 8a raises and the cutter 8 returns to an origin position by the traveling rail 9b moving to a horizontal direction.

  Thereafter, as shown in FIG. 7, the drive device 2, the upper roller 4 a, and the drive drum 7 are driven, and the upper end of the paper end on the side of the excluded paper roll 6 on which the double-sided tape is adhered by cutting with the cutter 8 The core 6a is adhered to the exclusion paper roll 6 and wound.

  Here, since the diameter of the reject paper roll 6 increases as the winding amount increases, the arm 6b that supports the core 6a is wound up while being lifted by the lifting cylinder 6d.

  As a result, the core 6a on which the roll paper is wound is cut at the gaps between the roll papers, and then the one-day excluded paper rolls 6 are collectively transported to a disposal site by a crane or the like for disposal.

On the other hand, the cut roll paper on the side of the log roll 1 is rotated by rotating the lower roller 4b of the pair of pull-in rollers 4 while being pinched with a drive motor (not shown) clockwise about the support shaft 4c. And the nipping by the upper roller 4a and the lower roller 4b is released.
Then, the plurality of log rolls 1 from which the paper splicing portion has been removed are rotated clockwise by the driving device 2, and the paper ends on the log roll 1 side cut by the existing tape sticking device 10 (the existing bonding device 10) are rotated. Each tape (adhesive) is affixed and wound around each log roll 1 and shipped as a product.

Therefore, according to the roll paper splicing unit discharge device having the above-described configuration, the operator can turn on the roll paper splicing unit discharge device, and the plurality of log rolls 1 can be rotated by the drive drum 2, so Since the roll is automatically wound from the log roll 1 to the exclusion paper roll 6, the operator is troublesome and does not require a lot of work, and the burden on the operator can be reduced.
In addition, when the worker leaves the work site temporarily due to a break or the like, the machine automatically performs the cutting operation of the paper splicing part during that time, so it is not necessary to secure a substitute person and labor costs can be reduced.

  Furthermore, there is no need to provide a processing space for stacking the cut roll paper on the passage, and not only can the space in the site be used effectively, but there is no hindrance to traffic.

  The present invention is not limited to the above-described best mode. For example, a part of all log rolls 1 in which the same paper spliced portion is divided and wound in the width direction have an axis line. They may be arranged so as to be positioned on a straight line and rotated by the driving device 2, or only one log roll 1 may be rotated by the driving device 2.
