Abstract

PURPOSE:To make preparatory operation into automation and thereby aim at retrenchment in labor and time, by installing a forming device of a paper joint sticky layer for another web and a cutting break forming device extending over the whole range of width both in a frame body which intersects in a longitudinal direction of the web of newsprint and is free of reciprocating motion. CONSTITUTION:A driving rotary mechanism 22 of a sling supporting device 2 is driven, while paper 1 on the surface layer damaged dueing conveyance is delivered onto a table 12 as being detected by a sensor, and at the point that scratches vanish into nothing, the paper stops. Next, an arm 16C is turned round, delivering a double-faced table 15, and pulled out of a needle member 16F, whereby a traveling frame body is moved forward and, after sticking a tape 15 up to its a loose end part to a web 1, this frame body is reverselymoved, making a cutter 17E go down to its cutting position, the traveling body is made to reciprocate whereby it forms a blocked break (a) along a shifting route to the web 1. And, a rubber roller 13A is forcibly pressed to the web 1, and with rotation of this roller, the web 1 is cut in halves along the blocked breaks (a) and (a) formed in V-shaped, thus paper point pre-treatment can be automated.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is directed to the use of peeled newspapers in a preparatory work for splicing a plurality of newspaper rolls attached to a newspaper roll supply reel to a rotary press. A stone related to pre-processing technology for splicing newspaper rolls, which involves cutting the ends of the roll into a shape suitable for splicing, and forming an adhesive layer on the ends for splicing.

[Conventional technology]

As shown in Fig. 11, when one of the newspaper rolls (1) attached to the newspaper roll supply reel (D) to the rotary press 1cI runs out, the terminal end of this paper roll (1) is placed next to the newspaper roll (1). It is necessary to splice it to the starting end of a new newspaper roll (1), but the following steps are generally taken as preparatory work for this paper splicing. ) to (c), cut the 5th to 5th sheet from the surface near the end of the newspaper roll (1) to avoid damage caused by loose winding during transportation and damage. Peel off the S- layer on the surface that is likely to be attached.

(1) As shown in Figure 12) to (G), after folding the left and right ends of the newspaper roll (1) into a triangle, hold down the main body side with one hand, and fold the left and right ends of the newspaper roll (1) into a triangular shape. Tear off the paper and form the ends of this web (1) into a triangular shape suitable for paper splicing.

I As shown in Figure 12 (A) and ('J), a convex tab is attached to the top of the triangular end (1a) of the web (1). Attach the tail to the main body side of the roll paper (1).

(G) As shown in Figure 12 (N) and Q, the roll paper (
A double-sided tape for paper splicing (an example of an adhesive layer for paper splicing) (I51) having a greater adhesive force than the tab (I51) is manually applied to the outer peripheral surface of the triangular end (1a) of 1). Paste it.

In addition, (goods) in Figure 11 is the following new newspaper roll (1
) is the same as the feeding speed of the newspaper roll (1) just before the end of use.
Or ha)? ['This is a drive belt to maintain the same circumferential speed, and (5) is a drive belt that moves the end of the paper roll (1) that is about to end its use to the next new newspaper (1) based on the detection signal of the paper remaining amount detection sensor. This is a device that presses the double-sided tape o5.

[Problem that the invention seeks to solve]

In such conventional preparatory work, the process of cutting the end of the paper roll (1) into triangles and applying the double-sided tape are all done manually, and furthermore, these processes are time-consuming. Since they are completely separated, there is a problem in that the preparatory work as a whole requires a great deal of effort and time.

The first object of the present invention is to efficiently perform preparatory work for splicing newspaper rolls with less effort, and the second object is to improve the process for achieving the first object. It is an object of the present invention to make it possible to reliably perform both the cutting process of newspaper rolls and the process of forming an adhesive layer for paper splicing, through a reasonable improvement.

[Means for solving problems]

The characteristic configuration of the splicing pretreatment device for newspaper rolls according to the first aspect of the present invention is that the newspaper roll (1) is mounted on a frame (9) that can be driven and reciprocated in a direction intersecting the longitudinal direction of the newspaper roll (1).
1), a paper splicing adhesive layer (151) is applied to another newspaper roll (1) over an appropriate length along its reciprocating path.
The present invention is characterized in that a device (1η) is provided to form a separation cut (al) in the newspaper roll (1) over almost the entire width of the newspaper roll (1).

The effects of the above feature configuration are as follows.

[For production]

In other words, the adhesive layer forming step by the adhesive layer forming device 00 provided on the frame (9) and the separation cut forming step by the cut forming device 0η are performed by the forward and backward movements of the frame (9), time and return. Since it can be carried out consecutively during forward movement, or simultaneously during forward or backward movement, it is possible to automate both processes, eliminating the waiting time between both processes. Or it can be reduced as much as possible.

〔Effect of the invention〕

Therefore, the preparatory work for paper splicing, the step of cutting the end of the newspaper roll into a shape suitable for splicing, and the step of forming an adhesive layer for paper splicing, can be carried out efficiently with less labor.

[Means for solving problems]

The characteristic configuration of the splicing pretreatment method for newspaper rolls according to the second invention is that when the frame body (9), which can be driven and reciprocated in a direction intersecting the longitudinal direction of the newspaper rolls (1), is moved back and forth, The adhesive layer forming device (161 provided with this frame 191K) forms an adhesive layer a8 for paper splicing onto another newspaper roll (1) along the reciprocating path, and
) during the backward movement of the frame (9), the cut forming device a provided on the frame (9) makes #1t of the width of the newspaper roll (1)! It is located at the point where a closed cut (al) is formed over the entire area.

The effects of the above feature configuration are as follows.

[For production]

In other words, by performing the process of forming an adhesive layer for paper splicing, which requires applying a strong tensile force to the newspaper roll (1), before the cut formation process, wrinkles are generated in the roll of paper (1). The viscous M layer 09 can be formed smoothly without any process. Moreover, since the separation cut is formed in a closed state, the paper web (1) will not be misaligned or wrinkled due to cutting, for example, when cutting from the edge of the paper web (1). Can cut accurately and smoothly.

〔Effect of the invention〕

Therefore, by simply improving the cutting process of the newspaper roll (1) and the process of forming the paper splicing adhesive layer (151) as described above, it has become possible to perform both of these processes reliably and quickly. .
