Description

Detailed Description of the Invention (Industrial Field of Application) The present invention is mainly used as accessory equipment for rotary presses, and is an automatic device for automatically pre-processing the starting end of a web for paper splicing. Related to pre-processing equipment for paper IT.

(Prior Art) In general, in a single rotary press 103, as shown in FIG. Continuous feeding of paper to the rotary press m1o3 is performed by adhesively splicing the starting end of the rolled paper 104 using a pressing device 105. In the figure, 106 is a trident for supporting the web, and 107 is a device for moving the web 104 once.

In order to perform the automatic splicing of the paper roll 10=1, it is necessary to perform splicing A'ff processing on the starting end of the paper roll 104, but this pre-processing is usually performed manually. That is, after peeling off the outer surface layer of the web 104 with a spatula or the like, the starting end of the web 10.1 is cut into a substantially V shape as shown in FIG. 10.1, and a double-sided adhesive tape 109 is attached to the outer surface of the starting end of the ■-shape to form a plurality of adhesive layers.

However, manual pretreatment for paper splicing has a problem in that work efficiency is low, resulting in high labor and IP costs, and the interior of the paper is likely to be damaged when the outer surface layer of the web 104 is peeled off.

Therefore, in order to solve the above-mentioned torture in the manual pre-processing for paper splicing, a person skilled in the art has developed an automatic paper splicing pre-processing system R1 that can automatically pre-process the web 104 for paper splicing. ing. As this type of automatic paper splicing pretreatment device, there is known, for example, a Mizuzukuri device disclosed in Japanese Patent Application Laid-Open No. 12561/1983.

That is, the automatic paper splicing pre-processing device is shown in FIGS. 28 and 2.
As shown in FIG. 9, there is provided a support device 110 installed near the entrance path for the web 104 into the rotary press, which rotatably suspends and supports the web 104 and moves it vertically and horizontally; a table 111 for supporting and placing the starting end of the web 104; a pivotable guide rail 112 disposed above the table 111; The groove is formed by a main processing device 113 that includes a cutter device for attaching a cutter device, an adhesive layer forming device for attaching a double-sided adhesive tape 109 for guiding the paper to the starting end of the paper roll 104, a tab tape supply device, and a paper feeding device. There is.

Thus, cutting and removal of the surface layer of the web 104 supported by the support device 110 is performed using a cutter device and a suction device (
(not shown).

Next, the starting end of the web 104 is rolled out onto the table 111, and the double-sided adhesive tape 109 is applied to the starting end using an adhesive layer forming device and a cutter device, and a substantially V-shaped cut is formed.

Thereafter, the starting end is separated and separated along the cut, and the tab tape 109 is applied to the tip of the approximately V-shaped starting end using the double-sided adhesive tape 109 of the tab tape supplying device and the adhesive layer forming device.
One end of 08 is pasted.

After rewinding the web 104, the tab tape 1
The other end of the web 104 is attached to the outer surface of the body of the web 104 using the double-sided adhesive tape 109 of the adhesive layer forming device.In this way, as shown in FIG. Pretreatment is performed.

However, in the automatic paper splicing pre-processing device, when the main processor 113 attaches the double-sided adhesive tape 109 to the starting end of the web 104 and forms the cuts, the guide rail 112 is first cleaned. 4 with respect to the axial direction of the web 104
After changing the posture to a position tilted at 5 degrees, the main processor 113 is moved along the guide rail 112 while pasting the double-sided adhesive tape 109 and forming the cut. After changing the posture to tilt at 45 degrees in the opposite direction to the core direction, the main processor 1
13 is moved along the guide rail 112 while attaching the double-sided adhesive tape 109 and forming the cuts, it takes a considerable amount of time to attach the double-sided adhesive tape 109 and forming the cuts. There is a problem that it is difficult to improve work efficiency.

In addition, since the table 111 simply supports and places the starting end of the web LO4, the starting end of the web 104 can be tested on the table 111, and the main processor 113 applies the double-sided adhesive tape 109 and forms cuts. When carrying out this process, there is a problem in that the starting end may be misaligned or wrinkled, making it impossible to adhere the double-sided adhesive tape 109 and form the cut in a predetermined position well and reliably. As a result, various troubles occur, such as when pressing and bonding the terminal end of the used web 104 to the approximately V-shaped starting end of the new web 104, the adhesion between the two cannot be performed well and reliably.

Furthermore, since the support device 110 is formed into a gate shape and is fixed to the ceiling of a building, there is a problem in that the automatic paper section preprocessing device itself becomes large and requires a large installation space.

(Problems to be Solved by the Invention) The present invention has been devised in order to solve the above-mentioned problems, and its purpose is to improve the work efficiency of paper splicing pretreatment, and to To provide an automatic paper splicing pre-processing device which can satisfactorily and reliably form adhesive material and cuts at predetermined positions at the starting end of a web of paper, and which can make the device itself more compact.

Note that the tab pasting device 5 is not limited to that of the above embodiment, and if it can peel off the floor covering paper 8 and stick one end of the tab 68 to the tip of the approximately V-shaped starting end of the web 1, It may be of any structure and format.

Next, we will explain the pre-processing of the web 1 for one puzzle using the automatic paper splicing pre-processing device. After the outer surface layer of the web 1 is sucked upward by a suction disc provided on the upper support frame 30, the surface layer is cut in the width direction by a cutter blade 100 also provided on the support frame 30 (
(See Figure 18).

When the cutting of the surface layer of the paper web 1 is completed, the surface layer of the paper web 1 is removed, the winding paper 1 is rotated, and its starting end is fed out onto the top surface of the table 2. It is suctioned and fixed to the top surface (see Figure 19).
.

When the starting end of the web 1 is suctioned and fixed, the pair of main processors 4 move synchronously in a predetermined direction along the guide body 29.
A substantially V-shaped cut 101 and an adhesive layer are formed at the starting end (see FIG. 20).

Thereafter, the apex portion of the approximately V-shaped starting end of the web 1 is cut by the cross-cutting cutter device 56 (see FIG. 20).
.

Then, the starting end of the web 1 is cut off along the cut line 101 (see FIG. 21).
When the separation of the starting end is completed, one end of the tab 68 is stuck to the tip end surface of the approximately V-shaped starting end by the tab pasting device 5 (the 22nd (see figure).

When one end of the tab sheet 1 is attached to the substantially V-shaped starting end, the starting end of the web 1 is rewound while being squeezed by compressed air blown out from a nozzle 102 provided on the support frame, and the tab 68 is unwound. The other end is attached to the outer surface of the body of the web 1 (see FIG. 23). Note that when the starting end of the paper roll 1 is rewound, air is blown upward from the table 2 to prevent the tab 68 from hitting the top surface of the table 2.

In this way, the web 1 is pre-treated for splicing.

It should be noted that the operations of each of the above-mentioned devices are automatically performed according to preset signals from the control device.

The web 1 that has been pretreated for paper splicing is rotated at a speed equal to the feeding speed of the web 1 being fed to the rotary press, and the end of the used web 1 is transferred to the new web 1. When pressed on the starting edge, both papers will form a splicing adhesive layer and tab 6.
At the same time, the adhesive layer 67 formed in 8 is used for adhesive connection.
As shown in FIG. 25, the tab 68 is cut off along the cut 85 formed in the tab 68, and the starting end of the new web l is continuously fed to the rotary press. At this time, it goes without saying that the paper splicing adhesive layer and the protective paper 84 of the adhesive layer 67 of the tab 68 have been peeled off.

(Effects of the Invention) As described above, the automatic paper splicing pre-processing device of the present invention has a pair of main processing devices arranged above the table to form a substantially V-shaped cut and an adhesive layer at the starting end of the web. The structure is such that both main processors form cuts and adhesive layers, compared to conventional automatic paper splicing pre-processing equipment that performs cuts, adhesives, and adhesive layer formation in one main processor. and the formation of an adhesive layer quickly turns blue.

As a result, the work efficiency of paper splicing pretreatment can be greatly improved.

In addition, the table of the automatic paper splicing pre-processing device is equipped with a suction device that can suction and fix the starting end of the web to the top surface of the table, so when forming the cut and adhesive layer on the starting end of the web, There is no possibility of the starting end slipping or wrinkling, and there are no cuts and adhesive H at the predetermined position of the starting end.
can be formed satisfactorily and reliably. As a result, the pre-processing for paper splicing can be performed satisfactorily and reliably, and the automatic splicing of web sheets can also be performed satisfactorily.

Furthermore, since the automatic paper splicing pre-processing device has a structure in which the support device is disposed below the table, the device is more efficient than the conventional automatic paper splicing pre-processing device that uses a concave support device. It is extremely convenient because it can be made compact and requires only a small installation space.
