Abstract

PURPOSE:To automatically splice paper sheets, by providing such an arrange ment that, when a rolled paper sheet on feeding is consumed, the leading end of a stand-by rolled paper sheet is automatically spliced on the rolled paper sheet on feeding, and then the paper sheet on feeding is severed on the way of the conveying path. CONSTITUTION:When a roller paper sheet on feeding is consumed, one of limit switches 7, 8 is turned on to drive a cylinder 39 and a motor 18, and a bisurface adhesive tape 41 applied on the leading end part of a stand-by roller paper sheet is adhered onto the rolled paper sheet on feeding. Further, the roller paper sheet on feeding is severed on the way of a conveying path, and therefore, the stand-by rolled paper sheet is then fed so that the splice of the paper sheets may be automatically made. Accordingly, it is not required that the operator manually splice the paper sheets, and therefore, the splicing operation may be simplified, and there is no possibility of missing the splice of the paper sheets due to erroneous operation or neglect of operation, thereby it is possible to enhance the reliability of the splice of the paper sheets.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an underlay feeding device that supplies underlay paper between the newspaper bundle and a conveyor section during shipping sorting of newspaper bundles, etc. The present invention relates to a mechanism for supplying a web to a cutting section for cutting the underlay paper.

As shown in the conventional Japanese Patent Application Publication No. 51-4728, a web of paper is sent out sequentially toward a cutting section, where it is cut into a predetermined length of underlay paper, and this underlay paper is inserted between a conveyor section and a bundle of newspapers. An underlay feeding device is known that feeds and dumps underlay.

In such an underlay supply device, when the paper roll runs out, it is necessary to replace it with a new paper roll, so
No. 1-4728, as shown in FIG. 6, a pair of webs σ and a/ are arranged side by side, one of the webs a is fed sequentially, and the other web a' is kept on standby.
A detector detects that the diameter of the roll has become thinner, and when it has become thinner to a certain diameter, a signal is emitted to notify the worker. Attach the double-sided adhesive tape C to the tip of the roll paper a', press the guide roller against the roller I using the lever d, and overlap the end of the other roll paper a' with the double-sided adhesive tape C pasted on the end of the other roll paper a'. By inserting it between the rollers, the tip of the other paper roll a' that was waiting at the end is glued, and from then on, the other paper roll a' is supplied, and in the meantime, a new paper roll is placed at the position of one paper roll a. I am telling you to put it on.

In Fig. 6, y is the drag roll, A is the cutting part,
The receiver consists of a blade 1 and a cutting blade.

Problems to be Solved by the Invention As mentioned above, since the underlay paper can be fed to each other from a pair of webs, it is possible to feed and lay the underlay paper without stopping. Therefore, the work is troublesome, and if the working tool is operated incorrectly or forgotten, the paper may not be spliced and the underlay paper cannot be fed, resulting in poor reliability.

Means and Effect for Solving Problems A pair of webs is passed through a conveyance path to the upper and lower surfaces of the plate, respectively, and a cylinder and a backing plate are arranged facing each other on the outlet side of the plate, and magnets are installed on the upper and lower surfaces of the plate. A cutting mechanism that moves the cutter using a motor is installed in the middle of each conveyance path, and double-sided tape is attached to the tip of the waiting paper roll so that it is positioned between the cylinder and the backing plate. A magnet is used to attract and support the plate, and a limit switch is installed adjacent to the pair of rolls to detect when the roll is out and drive the motor and cylinder. The tip of the paper roll being fed is automatically glued to the paper roll being fed, and the paper is cut in the middle of the conveyance path so that the paper can be spliced automatically.

Embodiment Figure 2 is an overall schematic diagram of the underlay feeder, including a counter stacker (not shown) and shipping equipment (not shown) prepared by Shimbun Togane.
The conveyor section A, which is provided between the newspapers (not shown) and conveys the bundle of newspapers, has a structure in which a waiting conveyor A' and a constantly driven conveyor B are provided. K is so that it can be sent in.

Reference numeral F denotes a web supply mechanism, on the supply side of which a pair of drag rolls 52 and a cutting section 53 are arranged in an eleventh order, and the cutting section 53 is composed of a pair of cutters 54 and 54.

FIG. 1 is a detailed explanation of the web supply mechanism F, and its structure will be explained below along with its operation.

In FIG. 1, 1 is a roll of paper for the old underlay paper in use, and the underlay paper is supplied to the paper guide 61 through a guide roll 15, a floating roll 13, a guide roll 16, a guide roll 34, and a guide roll 43. are doing. A third phototube 32 is provided on the exit side of the guide roll 16, and a fourth phototube 42 is provided on the inlet side of the guide roll 430. -2 is a roll paper for a spare new underlay paper, and the guide roll 1
7. After passing through the floating roll +4, jj guide roll 27, guide roll 28, and guide roll 35, the tip part is waiting at the entrance side position of the fourth phototube 42, and a double-sided tape 41 is pasted on the tip part. At the same time, the cylinder 39 is firmly held between the plate 36 and the magnet 38 so as not to move during standby, and is disposed opposite the tip. 33 is a fifth phototube provided on the exit side of the floating roll 14.

3.4 is a brake which is pressed against the outer periphery of each paper roll 1.2 by a lever 9.10 and springs I + and +2.

As the roll paper 1 for the old underlay paper is used, its diameter gradually becomes smaller, and the brake 3 also moves in an arc accordingly, but since the roll diameter detection bar 5 is provided coaxially with the brake 3, the roll diameter detection bar 5 is installed coaxially with the brake 3. The diameter detection bar 5 similarly performs an arcuate movement. When the stroke end (that is, the state in which the paper roll 1 for downstream paper is exhausted) is reached, the limit switch 7 is activated to issue a paper splicing signal.

C' is the downstream paper 1 provided between the guide roll 1 and the guide roll 34 in the conveyance path of the paper web 1 for the downstream paper.
A sprocket 20 provided on the output shaft 18a of the motor 18 is connected to a sprocket 21 via a chain 67, and a tin rocket 22 is provided coaxially with the sprocket 21. As shown in the figure, it is connected to the other sprocket 65 by a chain 66 with a sprocket wider than the width H of the old underlay paper, and the chain 66 is provided with a cutter 29. When the cutter 29 is cut and the limit switch 30 is operated, the motor 1g is stopped and the cutter 29 is also stopped.

The cutter 29 is a commercially available disposable and inexpensive one, and as shown in FIGS. 4 and 5, a special unit chain 66' is provided at one location of the chain 66, and this special unit chain 66'
A block 68 is provided in the block 68, and a cutter 29 is attached to this block 68.
It is fixed with presser foot &69 and bolt 70.

D is a cutting mechanism for the new underlay paper 2' provided between the 70-ching roll 14 and the guide roll 28 in the transport path of the new underlay paper roll 2; 4K has been constructed, so the explanation will be omitted by referring to the reference numerals.

As such, the downstream paper sheets 1' are sent out one after another, cut into a predetermined length by the cutting section 53 (see FIG. 2), and then sent to the paper guide 61 where they are forcibly fed out as the paper sheet 63.

Then, when the downstream paper roll 1 runs out, the limit switch 7 operates to issue a paper splicing signal.

This signal stops the paper feed, and the cylinder (that is, the air cylinder for paper splicing) 39 moves up to the abutting plate 40, activates the double-sided tape 41, and bonds the downstream paper 1' and the new paper 2'. After that, the cylinder 39 descends. When the paper splicing is completed, the motor 18 is driven and the cutter 29 cuts the downstream paper 1' as described above.

This completes the automatic paper splicing, and from this point on, new underlay paper 2' is sequentially supplied from the roll paper 2 for new underlay paper. Then, the magnet 38 is separated from the plate 36 due to the tension when being supplied, so that it does not interfere with the supply of the new underlay paper 2'.

Then, replace the paper roll 1 for the downstream paper that ran out while it was being supplied sequentially from the new paper roll 2 for the new paper for the paper roll, and replace it with a new paper roll, and insert the tip of the paper into the fourth light 'vli, at the population side position of the tube 42. The paper is fed until the end of paper is fed and double-sided tape is applied, and the paper is placed on standby until the next paper is spliced. However, in order to prevent the leading edge of the replaced new roll from moving during the waiting period, a magnet 37 is attached to the plate 36 to attach both sides of the leading edge. Slightly upstream from the tape attachment part 0tl
Hold the l firmly between them.

Then, when the new underlay paper roll 2 runs out, the limit switch 8 operates to output a paper splicing signal, and based on that signal, paper splicing is performed in the same manner as described above.As described above, paper splicing can be performed automatically. Continuous intangible operation becomes possible.

In addition, if the old underlay paper vinyl 2' is not completely cut during automatic paper splicing, the third photocell 32 (fifth photocell 3
3), and the paper splicing defect is detected by the fourth phototube 42.

Effects of the Invention When the paper being fed runs out, one of the glue set switches 7 and 8 is turned on, driving the cylinder 39 and motor 18, and feeding the double-sided tape 41 attached to the tip of the waiting paper roll. By cutting the paper roll that is glued to the paper roll and being fed in the middle of the conveyance path, the paper roll that is waiting is then fed, so that paper splicing can be carried out visually.

Therefore, since the work C1 does not require paper splicing in the cow cutting process, the paper splicing process becomes simple, and reliability is improved since paper splicing is not impossible due to operational errors or omissions.
