Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for non-interfering with a corrugated board sheet by a ruled line roller and a slot roller in a corrugated sheet processing machine in which a paper feeding section, a printing section, a ruled line and a slot processing section are arranged in series. be.

As shown in Figure 1, multicolored pudding (21 (31)
The processing machine for applying the ruled line processing (4) and the slot processing (5) usually includes a cutter (6) for individually feeding out a large number of loaded corrugated cardboard sheets (1), as shown in Fig. 2. ), a paper feed section (A) equipped with a
The printing unit (BIXB2) is used to perform desired printing (23(3)) on the cardboard sheet fed from the
The slotter processing section (C) is provided with a pair of upper and lower ruled line rollers (7) (8) and a pair of upper and lower slot rollers (9) α1.

Such a corrugated board sheet processing machine is operated exclusively for the purpose of processing an unprocessed corrugated pole sheet (1) into the form shown in FIG. 1, as described above. However, with the increase in high-mix, small-lot processing in recent years, there are frequent cases where the above-mentioned processing machines do not require ruled lines and slots + processing, and only printing processing is required, and in order to meet this demand, , a pair of ruling rollers (7)
(8) A ruled line holder provided on the upper roller (7) and a pair of slotted rollers (9) (10 cutting blades (1)
1) The reality is that unless (b) is removed, labor and time are wasted.

The present invention aims to improve the above-mentioned situation and provide a method for eliminating the interference of ruled line rollers and slot rollers with corrugated paperboard sheets in order to efficiently carry out processing changeover work.

The method of the present invention will be explained below based on the drawings of the embodiments. As shown in Fig. 2, there is a paper feeding unit for feeding a large number of stacked cardboard sheets (1) one after another, the paper feeding unit It is equipped with a printing section (B1) (Bz) that performs desired printing on the corrugated paperboard sheet fed from the paperboard (body), a pair of upper and lower ruled line rollers (7) (8), and a pair of upper and lower slot rollers (9) QO. In a corrugated sheet processing machine in which a slotter processing section (C) is arranged in series, a pair of upper and lower ruling line rollers (7) (8) of the slotter processing section (C) are provided.
) and a pair of upper and lower slot rollers (9).
) With respect to the QO, as shown in FIG. 3, at least the cutting blade a◇0 provided on the upper slot roller (9) is raised to a position O where it can be separated from the lower roller a0, This processing operation involves passing the corrugated cardboard sheet transferred from the printing section through the slotter processing section.

The above-mentioned pair of ruling line rollers (7) (8) and the slot roller (9) and the upper roller (7) (9) of the QO.
) for raising or restoring the rollers (13) () of the upper rollers (7) (9), for example, as shown in FIG.
14) is attached to a supporter (16) that can move up and down relative to the machine frame (15) with its bearings (17) and (18), and the supporter (16) is attached with a screw shaft (19) or an azimuth screw. It is convenient for operation to be configured so that the left and right sides can be moved up and down by the same amount at the same time.

Next, a method of operating the corrugated board sheet processing machine according to the present invention will be described. Usually, the well-known corrugated sheet processing machine described above has a paper feed section (A) as shown schematically in FIG. The corrugated cardboard sheets (1) are sent out regularly and individually at regular intervals from the first printing section (B
In l), a print (2) of a predetermined color pattern is applied,
Subsequently, in the next printing section (B2), a print (3) with a different color pattern is applied, and if necessary, a multicolor pattern is printed on the surface of the corrugated board sheet (1) through the next printing section (not shown). The printed material is transferred to the slotter processing section (9), and in this slotter processing section (C), crease lines (4) (4) and After that, a pair of upper and lower slot rollers (
9) Form slots (5) (5) by QO,
It is used as a material for expanding cardboard cases, but sometimes it is possible to meet such demands extremely quickly by simply printing on a plain sheet. That is, the sorting machine is temporarily stopped, and the supporter supporting the axis Q3α→ of the upper ruled line roller (7) and slot roller (9)
(2) by rotating the screw shaft a Samurai so that at least the cutting edge 0υ (6) of the upper slot roller (9) is at least the thickness of the corrugated pole sheet (1) from the upper peripheral surface of the lower roller a0. When the material is raised to a level where there is a gap and the machine is operated in this state, the material sent out from the paper feed section (A) is subjected to the desired printing in the printing section (Bs) (Bz).
Even when the ruled line roller (7) and the slot roller (9) are rotating, the printed material is sequentially transferred without being processed by the rollers, thereby making it possible to obtain a processed product with only prints. After the above processing is completed, screw 1t4i
1H to lower the upper ruling roller (7) and slot roller (9) to predetermined positions, the normal processing described above can be resumed immediately.

In this way, the corrugated board rollers (7) (8) of the ruled line roller and slot roller in the corrugated board sheet processing machine of the present invention
) and a pair of upper and lower slot rollers (9).
8) At least the upper slot roller (
9) is characterized in that the cutting blade αD(2) is raised at m−+ to the extent that it can be detached from the roller QO at the bottom, and only printing processing is performed.
Crease rollers (7) (8) and slot rollers (9) can be created in a significantly shorter time and with simpler work compared to conventional methods.
(+(The ship can be placed in a non-interfering state with respect to the corrugated board sheet, so even if printing only is required for in-line processing, it can be handled efficiently and in a short time.) The cutting area is immediately returned to normal processing conditions, and processing of small lots of a wide variety of products can be carried out smoothly.
