2. Description of the Related Art FIGS. 5 to 7 are views for explaining a schematic structure of a conventional creasing slotter and a state of processing a corrugated cardboard sheet. The creaser slotter is installed in the paper discharge section of a cardboard box making machine. The paperboard (cardboard sheet) that is intermittently conveyed one by one after being stacked in the paper feed section in the previous process is manufactured according to the product (box) specification. This is a device for processing ruled lines and slotter grooves at corresponding predetermined positions. Explaining the structure, it is provided with a pair of ruled line rolls 12 and 13 provided above and below a traveling corrugated cardboard sheet 11 and a pair of slotter knives 14 and 15 provided downstream thereof. The mounting table 16a to which the upper ruled line roll 12 is fixed is fitted to the upper shaft 17, and the mounting table 16b to which the lower ruled line roll 13 is fixed is fitted to the lower shaft 18. Similarly, the mount 19a to which the upper slotter knife 14 is fixed is fitted on the upper shaft 20, and the mount 19b to which the lower slotter knife 15 is fixed.
Is fitted to the lower shaft 21. Each of the mounting tables 16a, 16
b, 19a and 19b are engaged shafts 17, 18 and 2 respectively.
0 and 21 are configured to rotate together with the shaft via a key (not shown), and are fitted slidably in the axial direction. Ruled line roll shafts 17 and 18 forming a pair up and down
Are axially supported by the frames 23a and 23b erected at the width end of the apparatus via a bearing 22 and rotate in opposite directions in conjunction with each other by rotation driving means (not shown).
Also, the upper shaft 20 and the lower shaft 21 of the slotter knives 14, 15
Are also configured in the same manner as the ruled line rolls 12 and 13, and are rotated in opposite directions in synchronization with each other. The upper carrier 24 is supported by shafts 25a and 25b having both ends fixed to the frames 23a and 23b, and the lower carrier 26 is similarly supported by shafts 27a and 27b having both ends fixed to the frames 23a and 23b. The upper carrier 24 and the lower carrier 26 are both configured to move synchronously via a conveying screw rod 28 and an interlocking rotating means of the screw rod, and the yoke plates 29a, 29b fixed to the carrier 24. Guide plates 30a, 3
0b and yoke plate 31 fixed to carrier 26
The upper slotter knife 14, the upper ruled line roll 12, the lower slotted knife 15, and the lower ruled line fixed to the mounting table via the mounting tables 16a, 16b, 19a, 19b with which the guide plates 4a, 4b of the a and 31b engage respectively. The roll 13 can be moved in a direction orthogonal to the flow of the sheet in the axial direction in conjunction therewith. With the above structure, a pair of upper and lower ruled line rolls 12 and 13 and upper and lower slotter knives 14 and 1 are formed.
5 can be moved and installed at the same position in the axial direction.
The plurality of carriers 24 supported by the shafts 25a and 25b and the plurality of carriers 26 supported by the shafts 27a and 27b are respectively screwed with separate transport screw rods (not shown) and moved independently. It can be installed at any position corresponding to the shape of the box to be manufactured.

Next, the function of the ruled line rolls 12 and 13 will be described. The ruled lines are for folding the corrugated cardboard sheet 11 in box making. As shown in FIG. 9, the corrugated cardboard sheet 11 conveyed from the previous process is first made to correspond to the center of the slot of the post-process slotter by the ruled line rolls 12 and 13 first. Fold lines are applied. The ruled line roll has
Two assemblies are arranged on the straight line in the sheet running direction to prevent the sheet from being broken, and once an appropriate pressing deformation is given to one set on the upstream side, and then the next set (second ruled roll) forms a reliable folding line. It is configured to apply.

[0004] By the way, there are various ways of assembling the product corrugated cardboard box as shown in FIGS. 8 to 11, depending on the purpose of use, such as the condition of the contents to be filled, appearance, correspondence with the lid, and the like. As shown in FIG. 10, when the inside of the box is emphasized and the outside is attached, or when the appearance is emphasized and the inside is attached as shown in FIG. 11, the position of the ruled line close to the sheet glued portion is processed in a later process. It is necessary to shift the slotter groove sensor to the A side or the B side in FIG. These ruled line rolls 1
Up to now, as the position changing method of No. 3, a method of correcting the carrier means 26 side as shown in FIGS. 12 to 15 has been adopted. That is, when the lower ruled line roll 13 is moved to the left side in the figure as shown in FIG. 4, the guide plate 4b is removed from the yoke plate 31b, the shim 32 having a predetermined thickness is inserted, and the assembly is performed again. Conversely, when the ruled line roll 13 is moved rightward in the figure as shown in FIG.
(b) The guide plate 4b is removed from the lower carrier 26, and a shim 32 having a predetermined thickness is extracted and reassembled. By the above operation, the position of the guide plate 4b is changed with respect to the lower carrier 26 corresponding to the slotter groove, and the position of the ruled line roll 13 fixed to the mounting base 16b with which the guide plate 4b is engaged is moved. Since these operations are performed in a narrow place inside the apparatus, the workability is poor, and the guide plate 4b,
It is necessary to disassemble and assemble the yoke plate 31b, which requires a lot of time.

[0005]

As described in the section of the prior art, there are cases where the inside of a corrugated cardboard box is regarded as important depending on the purpose of use and where the outside is regarded as important. It is necessary to shift the ruled line position with respect to the slotter groove center depending on the use purpose of the box. However, the crease roll mounting base is configured to work in conjunction with the associated slotter. To change the position of only the crease roll, a shim having a predetermined thickness is attached to a part of the conveyance means engaged with the crease roll mount. , Or conversely, a white sheet of a predetermined thickness is removed, and the installation position of the ruled line roll mounting base is changed. In these operations, it is necessary to disassemble and assemble the yoke plate and the guide plate, which are the means for transporting the mounting table, and it is not only difficult to perform the operation, but also takes a long time for adjustment. Therefore, there are problems such as a decrease in the operation rate of the apparatus and a decrease in productivity. An object of the present invention is to provide a ruled line roll position changing device which solves the above-mentioned problems.

[0006]

Another ring (table) that can be further slid in the axial direction is added to the above-described conventional ruled line roll mounting table.
And means for moving the ring (table) are provided, and the ruled line roll is fixed to the ring. By moving the ring in the axial direction by a predetermined amount, the ruled line position can be moved relative to the mounting table. As a means for moving the ring, for example, a nut screwed to a screw formed on a mounting base is rotated and moved, and the ring is fixed to the nut.

[0007]

According to the present invention, the ruled line position can be independently moved in the axial direction with respect to the mounting table. Therefore, for the carrier, the yoke plate and the guide plate, which are the transfer setting means of the mounting table,
The known conventional type can be diverted as it is, and difficult work such as division and assembly performed in the single movement is eliminated.
As a result, the adjustment time can be shortened, so that the operation rate of the apparatus, that is, the productivity can be improved.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the ruled line roll position changing device of the present invention will be described with reference to FIGS. A crease roll mounting base 2 that engages with and slides on the crease roll shaft 1
A ring 3 that can move axially upward is fitted, and a ruled line roll 6 is fixed to the ring 3. The mechanism (transport device) related to the setting of the movement of the mounting base 2 in the axial direction is the same as that described in the section of the related art.

Next, the structure of the present apparatus will be specifically described. A cylindrical mounting base 2 is fitted to the upper and lower ruled line roll shafts 1. The mounting table 2 is moved to a predetermined position on the ruled line roll 1 by a conveying means such as a guide plate 4 (see FIG. 5) engaged with an annular groove 2a provided on the outer periphery, and is rotated integrally with the ruled line roll 1 by a key 10. I do. A screw 2b is formed at the opposite end of the annular groove 2a of the mounting base 2, and a nut 5 is screwed into the screw 2b. A ring 3 is slidable in the axial direction on the outer periphery of the mounting base 2 via a key 7. And non-rotatably fixed. The ruled line roll 6 is fixed to the ring 3 by bolts 8, and the ring 3 and the nut 5 are fixedly connected by bolts 9 passing through a plurality of bolt holes 5 a provided in the nut 5. Therefore, when the ruled line roll 6 is worn or damaged, it can be easily replaced or replaced by removing the bolt 8.

Next, the operation of the present apparatus will be described. When moving the ruled line roll 6 with respect to the mounting table 2 engaged with the ruled line roll shaft 1 via the key 10, first remove the bolt 9, rotate the nut 5 in a desired direction, and then remove the hole 9. The bolt 9 is screwed in a predetermined position where the screw matches, and the ring 3 is fixed again. In the example shown in FIG. 2, twelve bolt holes 5a are formed, and a displacement corresponding to 1/12 of the nut screw pitch can be obtained stepwise by shifting one hole. In the embodiment shown in FIGS. 3 and 4, the ring 3 and the ruled line roll 6 have an integral structure, and the nut 5 has a plurality of arc-shaped long holes 5b. 3 and 4, the amount of movement of the ruled line roll 6 can be adjusted steplessly.

The present invention is constructed and functions as described above. In setting the movement of the mounting table 2, the conventional conveying means interlocked with the slotter knife can be diverted as it is, and the ruled line roll 6 is moved to the slotter groove. Since only the position can be moved alone, the operation is simple and the adjustment time can be greatly reduced.

[0012]

As described above, according to the present invention, in a device for moving a slotter and a ruled roll as a pair, a cylindrical mounting base is fitted on a ruled roll shaft, and the ruled line is inserted via the mounting base. Since the relative position of the roll with respect to the slotter position is fixed so as to be adjustable, the upper and lower ruled rolls for performing ruled line processing on the corrugated cardboard sheet can set the relative position with respect to the slotter position to an arbitrary position independently within a predetermined range. The ruled line can be machined at any position in the groove width direction with respect to the center of the corresponding slotter groove, and it is not necessary to disassemble and reassemble the transfer means of the mounting table when changing the ruled line position as in the conventional method. In addition to the above, there is an effect that the labor can be saved, the adjustment time can be shortened, and the operation rate and productivity of the apparatus can be improved.
