In order to solve the above-mentioned problems, in the second invention, three first wall plates connected in the horizontal direction and a second wall connected to one edge in the vertical direction of the first wall plate are connected. It is a method of manufacturing a blank sheet for partitioning which comprises a plate and a flap connected to the other edge portion in the vertical direction of the first wall plate. First, a corrugated cardboard base sheet is prepared in which two parallel first horizontal ruled lines extending in the horizontal direction and a second horizontal ruled line extending in the horizontal direction are formed at a vertical interval. .. Next, with respect to the base material sheet moving in the vertical direction, two vertical ruled lines serving as both side edges of the first wall plate in the center are formed by a cleaner that rotates about an axis in the horizontal direction. Further, by the cutting blade attached to the outer peripheral portion of the slotter rotating about the axis in the lateral direction, a slit serving as a boundary between the adjacent second wall plates and a boundary between the adjacent flaps is formed on the extension line of the vertical ruled line. Form to.

In the method for producing a blank sheet for partitioning according to the present invention, the base sheet on which the first horizontal ruled line and the second horizontal ruled line are formed is moved in the vertical direction and passed through a cleaver and a slotter to allow the base sheet to pass through a first horizontal ruled line. One wall plate, second wall plate and flap can be formed. As described above, in the method for manufacturing a blank sheet for partitioning of the present invention, it is not necessary to stop the base sheet when processing the base sheet, so that the blank sheet for partitioning can be continuously manufactured at high speed.

In the method for manufacturing a blank sheet for partitioning, the cleaner and the slotter are provided in a transport path for moving the base sheet in the vertical direction, and two of the four cleaners arranged in the horizontal direction are used. , The vertical ruled line is formed on the base material sheet. Further, two of the four slotters arranged in the horizontal direction form the slit in the base material sheet.

In this configuration, the partition blank sheet can be manufactured without removing the cleaver and the slotter from a general flexo folder gluer (FFG) capable of manufacturing the A-type packaging box, so that the manufacturing cost of the partition blank sheet can be reduced. ..

In the method for manufacturing a blank sheet for partitioning, the first scorer and the second scorer of the corrugator are arranged side by side in the horizontal direction, and the ruled line roller of the first scorer and the ruled line roller of the second scorer are vertically arranged. Place them in a staggered manner. Then, by moving the base material sheet in the lateral direction and allowing the base material sheet to pass through the first scorer and the second scorer, the two ruled line rollers allow the base material sheet to have two firsts. Form a horizontal ruled line.

In this configuration, by arranging the two scorers side by side in the moving direction of the sheet, it is possible to prevent the ruled line rollers of both scorers from interfering with each other in the lateral direction intersecting the moving direction of the sheet. As a result, the distance between the two ruled line rollers in the horizontal direction can be narrowed, and the distance between the two first horizontal ruled lines can be narrowed.

The blank sheet for partitioning of the present invention has a high soundproofing effect and can form a partition in which the height of the wall can be changed according to the usage conditions. Further, since the blank sheet for partitioning of the present invention is made of corrugated cardboard, it can be easily discarded and recycled, and the remaining period of the virus adhering to the surface is shortened, which is effective in preventing the spread of the virus.

A flap 31 on the right side is continuously provided on the other edge portion of the first wall plate 11 on the right side in the vertical direction via a second horizontal ruled line L3 extending in the lateral direction.
Each of the flaps 30 and 31 is a band-shaped portion extending in the lateral direction.

The second horizontal ruled line L3 of the present embodiment is a corrugator ruled line which is a linear groove formed by the corrugator 100 (see FIG. 8) for manufacturing the base sheet S1 (see FIG. 8) of the blank sheet S.
The central flap 30 and the left flap 31 are separated by a second slit L12 extending in the vertical direction. Further, the central flap 30 and the right flap 31 are separated by a second slit L12 extending in the vertical direction.

When the blank sheet S of the present embodiment is transported and stored, as shown in FIG. 2, the left and right first wall plates 11 and 11 are folded back with respect to the central first wall plate 10, and the central first wall plate 10 is folded back. The left and right first wall plates 11 and 11 are overlapped on the inner surface of 10. At this time, the left and right second wall plates 21 and 21 overlap on the inner surface of the central second wall plate 20, and the left and right flaps 31 and 31 overlap on the inner surface of the central flap 30. In this way, the blank sheet S can be transported and stored in a folded state.

Next, when forming the partition 1 from the blank sheet S, first, as shown in FIG. 3, the blank sheet S is placed on the work surface with the inner surface of the central first wall plate 10 facing up. Then, the left and right first wall plates 11 and 11 are bent upward along the vertical ruled lines L1 and L1 with respect to the central first wall plate 10, and the left and right first wall plates 11 with respect to the central first wall plate 10 are bent upward. , 11 are launched vertically.
At this time, along with the left and right first wall plates 11 and 11, the left and right second wall plates 21 and 21 also stand up perpendicular to the central second wall plate 20. Similarly, the left and right flaps 31 and 31 stand up perpendicular to the central flap 30 together with the left and right first wall plates 11 and 11.

Subsequently, the flap 31 on the left side of the second wall plate 21 on the left side is bent toward the inner surface side of the second wall plate 21 on the left side at the second horizontal ruled line L3, and the flap 31 on the left side is left side with respect to the second wall plate 21 on the left side. The flap 31 of the above is arranged vertically. Similarly, the right flap 31 is bent with respect to the second wall plate 21 on the right side, and the flap 31 on the right side is arranged vertically with respect to the second wall plate 21 on the right side.

Further, the central flap 30 is bent toward the inner surface side of the central second wall plate 20 at the second horizontal ruled line L3 with respect to the central second wall plate 20, and is central to the central second wall plate 20. The flap 30 is arranged vertically. Then, the left and right ends of the central flap 30 are overlapped on the outer surfaces of the left and right flaps 31, 31 and joined with an adhesive tape or an adhesive.

After that, as shown in FIG. 4, the blank sheet S is installed on the work surface with the flaps 30 and 31 facing down. Then, the second wall plate 21 on the left side is folded back toward the inner surface side of the first wall plate 11 on the left side at the two first horizontal ruled lines L2 and L2 with respect to the first wall plate 11 on the left side. Similarly, the second wall plate 21 on the right side is folded back toward the inner surface side of the first wall plate 11 on the right side at the two first horizontal ruled lines L2 and L2 with respect to the first wall plate 11 on the right side. In this way, the second wall plate 21 is superposed on the inner surface of the first wall plate 11 to form a double wall.

Further, as shown in FIG. 5, the central second wall plate 21 is folded back toward the inner surface side of the central first wall plate 10 at the two first horizontal ruled lines L2 and L2 with respect to the central first wall plate 10. .. In this way, the second wall plate 20 is superposed on the inner surface of the first wall plate 10 to form a double wall.
When the central second wall plate 20 is folded back with respect to the central first wall plate 10, the central second wall plate 20 is pushed between the left and right second wall plates 21 and 21. As a result, the left and right edges of the central second wall plate 20 are pressed against the left and right second wall plates 21 and 21, so that the second wall plates 20 and 21 are difficult to return upward.

As described above, the central first wall plate 10 and the second wall plate 20 are arranged on the front surface, and the left and right first wall plates 11 and 11 with respect to the central first wall plate 10 and the second wall plate 20 are arranged. And the partition 1 in which the second wall plates 21 and 21 are bent toward the front side can be formed from the blank sheet S (see FIG. 1).

As shown in FIG. 6, the partition 1 of the present embodiment can be installed on a table with the flaps 30 and 31 facing upward.
Further, in the partition 1 of the present embodiment, as shown in FIG. 7, the first wall plates 10 and 11 and the second wall are formed without folding back the second wall plates 20 and 21 with respect to the first wall plates 10 and 11. The wall can be raised by connecting the plates 20 and 21 vertically.

In the blank sheet S as described above, as shown in FIG. 5, the second wall plates 20 and 21 are folded back on the inner surface side of the first wall plates 10 and 11 to form a double wall, whereby the soundproofing of the partition 1 is formed. The effect can be enhanced.

In the blank sheet S of the present embodiment, as shown in FIG. 7, the first wall plates 10 and 11 and the second wall plate 20 and 21 are not folded back with respect to the first wall plates 10 and 11. By connecting 20 and 21 vertically, the wall of partition 1 can be raised.

The remaining period of the virus attached to the surface of the corrugated cardboard is significantly shorter than the remaining period of the virus attached to the surface of the plastic plate. Therefore, in the partition 1 shown in FIG. 5 formed from the corrugated cardboard blank sheet S (see FIG. 1) of the present embodiment, the remaining period of the virus adhering to the surface is shorter than that of the plastic partition. Therefore, the partition 1 formed from the blank sheet S (see FIG. 1) of the present embodiment is effective in preventing the spread of the virus.

In the blank sheet S of the present embodiment (see FIG. 1), the second wall plates 20 and 21 are bent at the two first horizontal ruled lines L2 and L2 parallel to the first wall plates 10 and 11, so that the bent portion is bent. Can be stably formed. Thereby, the shape of the corner portion of the upper edge portion of the partition 1 can be stabilized.

Further, when the partition 1 is installed with the flaps 30 and 31 facing downward, the lower surfaces of the flaps 30 and 31 come into surface contact with the installation surface, so that the stability of the partition 1 is improved and the partition 1 is installed with respect to the installation surface. It becomes hard to be scratched.

Further, as shown in FIG. 6, when the partition 1 is installed with the flap side facing upward, the flaps 30 and 31 project inward from the upper edge of the wall, effectively blocking the line of sight from the outside. Can be.

As shown in FIG. 2, the blank sheet S of the present embodiment can be easily stored and transported by folding the left and right first wall plates 11 and 11 so as to overlap the central first wall plate 10.
Since the blank sheet S of the present embodiment is made of corrugated cardboard, it can be easily discarded and recycled.

Next, a method for manufacturing the blank sheet S according to the present embodiment will be described.
In the method for manufacturing the blank sheet S of the present embodiment, first, the first horizontal ruled line L2 and the second horizontal ruled line L3 are formed on the base sheet S1 by the corrugator 100 shown in FIG. Subsequently, the vertical ruled line L1, the first slit L11, and the second slit L12 are formed on the base sheet S1 by the box making machine 200 shown in FIG. 9, and the blank sheet S is formed.

The corrugator 100 shown in FIG. 8 is provided with a first scorer 110 and a second scorer 120. Using these two scorers 110 and 120, two first horizontal ruled lines L2 and L2 and one second horizontal ruled line L3 are formed on the base sheet S1.

The first scorer 110 is provided with a set of upper and lower sets of first ruled line rollers 111 and 111 and a set of upper and lower sets of second ruled line rollers 112 and 112.
On the outer peripheral surfaces of the upper and lower first ruled line rollers 111, 111, irregularities extending in the circumferential direction are formed over the entire circumference.
When the base sheet S1 passes between the upper and lower first ruled line rollers 111 and 111 in the lateral direction C1, the unevenness of the outer peripheral surfaces of both first ruled line rollers 111 and 111 is pressed against the outer and inner surfaces of the base sheet S1. , The first horizontal ruled line L2 is formed on the base sheet S1.
The first horizontal ruled line L2 is composed of two grooves formed on the outer surface of the base sheet S1 and one groove formed on the inner surface of the base sheet S1. A groove on the inner surface is formed at a position between the two grooves on the outer surface.

The upper and lower second ruled line rollers 112 and 112 are arranged at intervals in the vertical direction C2 orthogonal to the horizontal direction C1 with respect to the upper and lower first ruled line rollers 111 and 111.
The upper and lower second ruled line rollers 112 and 112 have the same configuration as the upper and lower first ruled line rollers 111 and 111. When the base sheet S1 passes between the upper and lower second ruled line rollers 112 and 112 in the lateral direction C1, the second horizontal ruled line L3 is formed on the base sheet S1.

The second scorer 120 is arranged side by side on the downstream side of the lateral direction C1 with respect to the first scorer 110. The second scorer 120 is provided with a pair of upper and lower third ruled line rollers 113, 113.
The upper and lower third ruled line rollers 113 and 113 have the same configuration as the upper and lower first ruled line rollers 111 and 111. When the base sheet S1 passes between the upper and lower third ruled line rollers 113 and 113 in the lateral direction C1, the first horizontal ruled line L2 is formed on the base sheet S1.

The first horizontal ruled line L2 formed by both the first ruled line rollers 111 and 111 and the first horizontal ruled line L2 formed by both the third ruled line rollers 113 and 113 extend in parallel with the lateral direction C1. The distance between the first horizontal ruled lines L2 and L2 in the vertical direction C2 is narrowly formed.

In the corrugator 100 of the present embodiment, since the two scorers 110 and 120 are arranged side by side in the lateral direction C1, both the first ruled line rollers 111 and 111 of the first scorer 110 and both the third ruled lines of the second scorer 120 are arranged. The rollers 113 and 113 are configured so as not to interfere with each other in the vertical direction C2 orthogonal to the horizontal direction C1.
As a result, in the corrugator 100, both the first ruled line rollers 111 and 111 and the both third ruled line rollers 113 and 113 can be brought close to each other in the vertical direction C2, and the distance between the two first horizontal ruled lines L2 and L2 can be increased. Can be narrowed.

As shown in FIG. 9, the box-making machine 200 of the present embodiment is a general flexofolder gluer (FFG) capable of manufacturing a type A packaging box.
The crystal slotter portion 210 of the box making machine 200 is a device for forming a vertical ruled line L1, a first slit L11, and a second slit L12 on the base sheet S1 while moving the base sheet S1 in the vertical direction C2.
The crystallizer slotter portion 210 includes four cleaners 220 that rotate around a lateral axis and four slotters 230 that rotate about a lateral axis.

The cleaner 220 is a disk-shaped member that rotates about an axis in the lateral direction C1 (direction orthogonal to the transport direction). Four creepers 220 are laterally spaced apart from one rotating shaft 221. A convex portion extending in the circumferential direction is formed on the outer peripheral surface of the cleaner 220.
When the base sheet S1 passes through each cleaner 220, the outer peripheral surface of each cleaner 220 is pressed against the inner surface of the base sheet S1 and rolls, so that a ruled line is formed on the inner surface of the base sheet S1. Two vertical ruled lines L1 and L1 are formed on the base sheet S1 by the second and fourth cleaners 220 from the right in FIG. 9. Further, a ruled line L5 is formed on the base sheet S1 by the third clezer 220 from the right in FIG.

The slotter 230 is a disk-shaped member that rotates about an axis in the lateral direction. Four slotters 230 are laterally spaced apart from one rotating shaft 231. Each slotter 230 is juxtaposed with respect to each crease 220 on the downstream side of the base sheet S1 in the transport direction. Cutting blades are attached to the outer peripheral surfaces of the second and fourth slotters 230 from the right in FIG. 9.

When the base sheet S1 passes through each slotter 230, the first slit L11 and the second slit L12 are formed on the extension of the vertical ruled line L1 by the cutting blades of the second and fourth slotters 230 from the right in FIG. Is formed.

Next, the manufacturing method of the partition 1 in the present embodiment will be described.
First, as shown in FIG. 8, the corrugated board sheet S1 is passed through the slitter scorer of the corrugator 100 in the lateral direction C1, and the first scorer 110 and the second scorer 120 pass the corrugated board sheet S1 into the base sheet S1. First horizontal ruled lines L2 and L2 and one second horizontal ruled line L3 are formed.

Subsequently, as shown in FIG. 9, the base sheet S1 on which the first horizontal ruled line L2 and the second horizontal ruled line L3 are formed is supplied to the transport path of the box making machine 200, and the base sheet S1 is provided in the vertical direction C2. And let it pass through the crease slotter portion 210.
In the crystallizer slotter portion 210, two vertical ruled lines L1 and L1 and another ruled line L5 are formed on the inner surface of the base sheet S1 by the three cleaners 220. After that, the first slit L11 and the second slit L12 are formed on the extension line of the vertical ruled line L1 by the two slotters 230.

In this way, the partition blank sheet S shown in FIG. 1 can be formed by using the corrugator 100 (see FIG. 8) and the box making machine 200 (see FIG. 9) capable of manufacturing the A-type packaging box.

In the method for manufacturing the partition blank sheet S of the present embodiment as described above, as shown in FIG. 8, the two scorers 110 and 120 of the corrugator 100 are arranged side by side in the moving direction of the base sheet S1. In this configuration, it is possible to prevent the ruled line rollers 111 and 113 of both scorers 110 and 120 from interfering with each other in the lateral direction intersecting the moving direction of the base sheet S1. As a result, the distance between the two ruled line rollers 111 and 113 in the horizontal direction can be narrowed, and the distance between the two first horizontal ruled lines L2 and L2 can be narrowed.

Further, as shown in FIG. 9, the base sheet S1 on which the first horizontal ruled line L2 and the second horizontal ruled line L3 are formed is moved in the vertical direction C2 and passed through the cleaver 220 and the slotter 230 of the box making machine 200. As a result, the blank sheet S can be formed. As described above, when the base sheet S1 is processed, it is not necessary to stop the base sheet S1, so that the blank sheet S can be continuously manufactured at high speed.

Further, since the partition blank sheet S can be manufactured without removing the cleaver 220 and the slotter 230 from a general flexo folder gluer (FFG) capable of manufacturing the A-type packaging box, the partition blank sheet S can be manufactured. Manufacturing cost can be reduced.

Further, in the method for manufacturing a blank sheet of the present invention, the depth of the ruled line can be easily adjusted as compared with the case where the ruled line is formed on the base sheet S1 by using the flat plate die cutter, so that the thickness of the base sheet S1 is increased. A ruled line with a depth suitable for bending can be formed accordingly.

In addition, when a flat die cutter is used when manufacturing blank sheets for partitions having different heights of the partition walls (that is, the vertical lengths of the first wall plate and the second wall plate), the walls are used. It is necessary to prepare a punching die for punching for each height, but according to the blank sheet manufacturing method of the present invention, base sheets of different sizes are prepared and the position of the ruled line roller of the corrugator is adjusted. The manufacturing cost can be reduced because it is only necessary to do so.
