The second wall includes a second frame plate connected to the first frame plate via a first folding line, and a second partition plate connected to the second frame plate via a third folding curve. , And the third wall is connected to the second partition plate via a second folding line and a third frame plate connected to the third frame plate via a fourth folding curve. A fourth frame plate is provided, and hinge wires are extended in the parallel arrangement direction on the second partition plate and the joint piece, and the first partition plate, the first frame plate, and the second frame plate are provided. A cutting line that is in the same straight line as the hinge line is extended to the frame plate and the third wall, the first wall is folded back at the first folding line and laminated on the second wall, and the joint is formed. The pieces are joined in the middle of the second partition plate, the third wall is folded back at the second folding line and laminated on the first wall and the second wall, and the tip end portion of the fourth frame plate is said. By being joined to the first frame plate, it becomes a folded form, and when the internal space of the box body is transformed into a partitionable form, the first frame plate and the fourth frame plate are formed. The first partition plate is relatively separated from the second partition plate, the first partition plate is raised while being rotated around the first folding curve and the second folding curve as a fulcrum, and the second frame plate is folded back to the first. The line and the third folding curve are raised while being rotated around the fulcrum, and the third frame plate is raised while being rotated around the second folding line and the fourth folding curve as the fulcrum, and the second partition is formed. The plate and the joint piece are folded back at the hinge line, and the first partition plate, the first frame plate, the second frame plate and the third wall are separated by the cutting line, whereby four cylinders are formed. The shaped partition space is formed in a grid pattern.

In this case, the sheet material is a corrugated cardboard sheet, and the hinge wire formed on the seam piece is a break line or a gap that breaks at least the upper surface of the seam piece when the seam piece is folded back. It is preferable that the double ruled lines are formed in parallel with the.

In this case, the first partition plate and the joint piece are formed so as to gradually narrow in the height direction orthogonal to the parallel arrangement direction toward the tip in the parallel arrangement direction, and are joined to the first frame plate. The tip end portion of the fourth frame plate to be formed may be formed so as to gradually narrow in the height direction toward the tip end portion in the parallel arrangement direction.

FIG. 2 is a perspective view showing a state in which the partition member 1 is housed in the box body 40. FIG. 3 is a plan view showing the blank 1A of the partition member 1.

As shown in FIGS. 1 and 2, the partition member 1 is housed in the internal space S1 of the box body 40, and divides (partitions) the internal space S1 of the box body 40 into four partition spaces S2. The box body 40 is, for example, a so-called A-type cardboard box in which the top opening and the bottom opening of a substantially square cylindrical peripheral wall 41 can be closed by a plurality of flaps 42. A plurality of products (not shown) are accommodated in the four partition spaces S2 partitioned by the partition member 1.

[Blank of partition member]
The partition member 1 is formed by appropriately bending one blank 1A shown in FIG. The blank 1A is formed by punching out a sheet of paper corrugated cardboard sheet (sheet material). The corrugated cardboard sheet is, for example, a double-sided corrugated cardboard sheet in which a front liner 9B and a back liner 9C (see also FIG. 1) are bonded to a corrugated cardboard 9A. Note that FIG. 2 shows the front liner 9B side. In the present specification, the direction parallel to the corrugated cardboard sheet 9A is referred to as "step direction", and the direction orthogonal to the step direction is referred to as "flow direction". “X” shown in the drawing indicates “step direction”, and “Y” indicates “flow direction”. Since the box body 40 is a general A-type box, the illustration of the blank of the box body 40 and its description thereof will be omitted.

As shown in FIG. 3, the blank 1A has the first wall 11, the second wall 12, and the third wall in order from one side (parallel direction) to the other side (from left side to right side in FIG. 3). 13 are arranged side by side in a row. The first wall 11 is connected to the second wall 12 via the first turnaround line 14, and the third wall 13 is connected to the second wall 12 via the second turnaround line 15. The first wall 11, the second wall 12, and the third wall 13 are formed in a substantially rectangular shape having substantially the same dimensions in the flow direction (height direction). The first wall 11 and the third wall 13 have substantially the same dimensions in the step direction, and the second wall 12 is formed longer in the step direction than the first wall 11 and the like.

<First wall>
The first wall 11 has a joint piece 20, a first partition plate 21, and a first frame plate 22. The joint piece 20, the first partition plate 21, and the first frame plate 22 are arranged side by side in a row in order from one side in the step direction to the other side.

The joint piece 20 is formed in a substantially trapezoidal shape that gradually narrows in the flow direction (height direction) toward one of the step directions (the tip (free end) in the parallel direction). Both sides of the passage piece 20 in the flow direction are inclined so as to approach each other toward the tip.

The first partition plate 21 is continuously provided at the other end of the joint piece 20 in the step direction via the first folding curve 31. The first partition plate 21 is formed in a substantially trapezoidal shape in which the width gradually narrows in the flow direction toward one of the step directions. That is, the first wall 11 has a shape that gradually tapers from the first partition plate 21 toward the joint piece 20. Both sides of the first partition plate 21 in the flow direction are inclined so as to approach each other toward one of the step directions. The tip sides of both sides (near the connection with the joint piece 20) are formed to have a steeper slope than the other portions.

The first frame plate 22 is continuously provided at the other end of the first partition plate 21 in the step direction via the second folding curve 32. The first frame plate 22 is formed in a substantially rectangular shape that is longer in the step direction than the first partition plate 21. The dimension of the first frame plate 22 in the step direction is set to substantially half of the dimension of the second partition plate 24 described later in the step direction. The other corner of the first frame plate 22 in the step direction is chamfered diagonally.

<Second wall>
The second wall 12 has a second frame plate 23 and a second partition plate 24. The second frame plate 23 and the second partition plate 24 are arranged side by side in a row in order from one side in the step direction to the other side.

The second frame plate 23 is continuously provided at the other end of the first frame plate 22 in the step direction via the first folding line 14. The second frame plate 23 is formed in a substantially rectangular shape, and its dimension in the step direction is set to be substantially the same as the dimension in the step direction of the first partition plate 21. One corner of the second frame plate 23 in the step direction is chamfered diagonally. The second partition plate 24 is continuously provided at the other end of the second frame plate 23 in the step direction via the third folding curve 33. The second partition plate 24 is formed in a substantially rectangular shape, and its dimension in the step direction is set to be substantially twice that of the first frame plate 22. The other corner of the second partition plate 24 in the step direction is chamfered diagonally.

<Third wall>
The third wall 13 has a third frame plate 25 and a fourth frame plate 26. The third frame plate 25 and the fourth frame plate 26 are arranged side by side in a row in order from one side in the step direction to the other side.

The third frame plate 25 is continuously provided at the other end of the second partition plate 24 in the step direction via the second folding line 15. The third frame plate 25 is formed in substantially the same shape as the second frame plate 23, and one corner portion of the third frame plate 25 in the step direction is chamfered diagonally.

The fourth frame plate 26 is continuously provided at the other end of the third frame plate 25 in the step direction via the fourth folding curve 34. The fourth frame plate 26 is formed in a substantially rectangular shape, and its dimension in the step direction is set to be substantially the same as the dimension in the step direction in which the first frame plate 22 and the joint piece 20 are combined. Although the details will be described later, the other end side in the step direction of the fourth frame plate 26 (the tip end side (free end side) in the parallel arrangement direction) is a portion joined to the first frame plate 22 (in the present specification, the "first". 2 is referred to as a joint piece 26A ”), and is formed in a substantially trapezoidal shape that gradually narrows in the flow direction toward the other side in the step direction. The second passage piece 26A has a shape in which the passage piece 20 is inverted around the center line in the step direction, and both sides in the flow direction are inclined so as to approach each other toward the tip.

<Notch>
As described above, the boundary corners between the adjacent first frame plate 22 and the second frame plate 23 and the boundary corners between the second partition plate 24 and the third frame plate 25 are chamfered diagonally. A substantially V-shaped (substantially triangular) notch 30 is formed at the boundary corner portion of the above so as to shorten the first turnaround line 14 and the second turnaround line 15.

<Hinge wire>
A hinge wire 16 extends in the step direction (parallel arrangement direction) at substantially the center of the flow direction between the joint piece 20 and the second partition plate 24 (a part of the second wall 12). The hinge wire 16 is, for example, a lead ruled line in which a plurality of cuts (perforations) are formed at predetermined intervals on a general-purpose ruled line obtained by crushing a corrugated cardboard sheet from the back liner 9C side in the thickness direction. The hinge wire 16 mainly has a function of folding back a corrugated cardboard sheet by approximately 180 degrees. Although the details will be described later, the hinge wire 16 formed on the passage piece 20 also functions as a breaking line that breaks at least the upper surface (front liner 9B) of the passage piece 20 when the passage piece 20 is folded back. The hinge wire 16 formed on the joint piece 20 is not limited to the lead ruled line, and for example, a full cut line obtained by completely dividing the joint piece 20, a half cut line cut to the middle of the thickness of the joint piece 20, and a plurality of pieces. It may be a perforation line or the like in which cuts are formed at substantially equal intervals, or it may be a double ruled line formed in parallel with a gap in between (neither is shown).

<Cut line>
A cutting line 17 is provided in the step direction (at the center of the flow direction of the first partition plate 21, the first frame plate 22, the second frame plate 23 (the portion excluding a part of the second wall 12), and the third wall 13 in the flow direction. It is extended in the parallel direction). The cutting line 17 extends to the first to third walls 11 to 13 excluding the joint piece 20 and the second partition plate 24 so as to be in the same straight line as the hinge wire 16. The cutting line 17 is, for example, a total cutting line obtained by completely dividing a corrugated cardboard sheet in the thickness direction. The cutting line 17 formed at the tip end portion (second joint piece 26A) of the fourth frame plate 26 has two seam portions 17A. That is, the second joint piece 26A is not completely divided in the flow direction by the cutting line 17, but is connected by the seam portion 17A.

The first to second folding lines 14 to 15 and the first to fourth folding curves 31 to 34 are lead ruled lines like the hinge line 16. Further, the 1st to 2nd turnaround lines 14 to 15 are weakened so as to break with a smaller force than the 1st to 4th turn curves 31 to 34. Specifically, the first to second turnaround lines 14 to 15 are set to have a shorter cut pitch than the first to fourth turn curve curves 31 to 34. In other words, the first to second turnaround lines 14 to 15 have the same cut length as those of the first to fourth turn curves 31 to 34, but have a large number of cuts and are general-purpose ruled lines. The portion is formed to be short. It is preferable that the ratio of the portion (seam) serving as the general-purpose ruled line of the first to second turnaround lines 14 to 15 is set to be smaller than 2/3 of the total length of the first to second turnaround lines 14 to 15. .. Further, the structure that weakens the first to second turnaround lines 14 to 15 more than the first to fourth turnover curves 31 to 34 is not limited to the above. For example, the first to second turn lines 14 to 15 may have a longer cut than the first to fourth turn curves 31 to 34. In this case, the number of cuts and the length of the portion to be the general-purpose ruled line may be the same. In addition, for example, the first and second turnaround lines 14 to 15 may be half-cut lines in which a cut is made halfway in the thickness direction from the front liner 9B side of the corrugated cardboard sheet.

The hinge wire 16 described above has a lead ruled line having the same structure as the first and second folding wires 14 to 15. Further, the hinge lines 16, the 1st to 2nd folding lines 14 to 15 and the 1st to 4th folding curves 31 to 34 are not limited to lead ruled lines and the like, and for example, general-purpose ruled lines and perforations are used to bend a corrugated cardboard sheet. Any structure can be used. Further, in the present embodiment, bending the corrugated cardboard sheet so that the back liner 9C faces inward is called "normal folding", and bending the corrugated cardboard sheet so that the front liner 9B faces inward is called "reverse folding". I will do it.

[Manufacturing process of partition members]
Next, an example of the manufacturing process of the partition member 1 will be described with reference to FIGS. 4 and 5. FIG. 4 is a perspective view illustrating a manufacturing process of the partition member 1. FIG. 5 is a perspective view showing the partition member 1 (folded form F1).

The corrugated board sheet is manufactured by performing a laminating step of corrugated board base paper using a device called a corrugated board (not shown). While advancing the middle shin 9A in the flow direction, the corrugated board attaches the liners 9B and 9C on both sides of the middle shin 9A, and cuts the corrugated cardboard sheet continuous in the flow direction to a predetermined length. The corrugator may form a folding curve, a cutting line, or the like extending in the flow direction.

The cut corrugated cardboard sheet is, for example, a packaging box or the like in a folded state after being processed into a blank by a device called a flexo folder gluer (not shown, hereinafter referred to as “FFG”). FFG continuously prints on corrugated cardboard sheets using flexo ink, scoring using blades (cutting blades, push blades, etc.) and punches, grooving and punching, and joining (pasting) using adhesives. It is a device to perform. Generally, the FFG is an apparatus for manufacturing an A-type box body 40. In the present embodiment, the cut corrugated cardboard sheet is processed into a blank 1A by the FFG, and the first wall 11, the second wall 12 and the third wall 13 of the blank 1A are bent by the FFG to form the partition member 1. The printing step may be omitted in the manufacturing process of the partition member 1. Further, as the adhesive, for example, a hot melt adhesive is used, but a synthetic resin emulsion adhesive, a double-sided tape, or the like may be used.

First, the FFG forms a hinge line 16, a cutting line 17, a first to second folding line 14 to 15, and a first to fourth folding curve 31 to 34 on a corrugated cardboard sheet, and a joint piece 20, a first partition. The plate 21 and the second joint piece 26A are formed in a substantially trapezoidal shape to form a notch 30. That is, the corrugated cardboard sheet is processed into the blank 1A. The first to second folding lines 14 to 15 and the first to fourth folding curves 31 to 34 extending in the flow direction of the corrugated cardboard sheet may be formed by a corrugator.

Next, the FFG applies the adhesive G to the joint piece 20 (back liner 9C), and folds the first wall 11 (first frame plate 22) forward along the first folding line 14. As shown in FIG. 4, the first wall 11 is folded back at the first turnaround line 14 (approximately 180 degrees) and laminated on the second wall 12, and the joint piece 20 (the tip end portion of the first wall 11) is formed. It is joined in the middle of the second partition plate 24 of the second wall 12. Specifically, the joint piece 20 is adhered to a position where the first folding curve 31 coincides with substantially the center of the second partition plate 24 in the step direction.

Subsequently, the FFG applies the adhesive G to the second joint piece 26A (back liner 9C), and folds the third wall 13 (third frame plate 25) forward along the second turnaround line 15. As shown in FIG. 5, the third wall 13 is folded back at the second turnaround line 15 (approximately 180 degrees) and laminated on the first wall 11 and the second wall 12, and the second passage piece 26A (third). The tip of the wall 13) is joined to the first frame plate 22 (middle of the first wall 11). Specifically, the second joint piece 26A is adhered to a position in the vicinity of the second folding curve 32 on the first frame plate 22. The first frame plate 22 and the fourth frame plate 26 are connected to each other via the second joint piece 26A and have substantially the same length as the second partition plate 24 in the step direction. In this specification, for convenience of explanation, the first frame plate 22 and the fourth frame plate 26 connected via the second passage piece 26A may be referred to as "connecting frame plate 27". be.

As described above, the partition member 1 which has been pasted and folded flat (folded form F1) is completed (see FIG. 5). The device for manufacturing the partition member 1 and the box body 40 is not limited to the FFG. For example, a printing device, a device for scoring and punching, and a device for pasting may be separate devices. The corrugated cardboard sheet (blank 1A) may be sequentially processed by these devices to manufacture the partition member 1 and the box body 40.

[Assembly of partition members]
Next, an example of the assembly process (procedure) of the partition member 1 will be described with reference to FIGS. 1, 2, 6 to 8. FIG. 6 is a perspective view showing the partition member 1 (intermediate form F2). FIG. 7 is a perspective view showing a process of transforming the partition member 1 from the intermediate form F2 to the partition form F3. FIG. 8 is a perspective view showing the partition member 1 (partition form F3).

The user receives the partition member 1 (see FIG. 5) in the folded form F1 and manually transforms the partition member 1 from the folded form F1 to the partition form F3 capable of partitioning the internal space S1 of the box body 40. ..

<Causing process>
When the partition member 1 is deformed from the folding form F1 to the partition form F3, the user grasps, for example, either one of the first wall 11 and the third wall 13 (or / and the second wall 12), and the second wall The partition plate 24 and the connecting frame plate 27 are separated from each other (causing step). Then, as shown in FIG. 6, the first wall 11 and the third wall 13 are relatively separated from the second wall 12, and the first wall 11, the second wall 12, and the third wall 13 are raised while being bent. Is done. Specifically, the first frame plate 22 and the fourth frame plate 26 (connecting frame plate 27) are relatively separated from the second partition plate 24, and the first partition plate 21 is folded into the first fold curve 31 and the second fold. The second frame plate 23 is raised while being rotated around the curve 32 as a fulcrum, the second frame plate 23 is raised while being rotated around the first folding line 14 and the third folding curve 33, and the third frame plate 25 is the second folding line. It is raised while being rotated around the line 15 and the fourth folding curve 34 as a fulcrum. More specifically, the first partition plate 21 is reverse-folded at a substantially right angle on the first folding curve 31 and forward-folded at a substantially right angle on the second folding curve 32. The second frame plate 23 is returned to a substantially right angle at the fold at the first turn line 14, and is folded at a substantially right angle at the second fold curve 32. The third frame plate 25 is returned to a substantially right angle at the fold at the second turn line 15, and is folded at a substantially right angle at the fourth fold curve 34.

When the raising process is completed, the second partition plate 24 and the connecting frame plate 27 are arranged so as to face each other substantially in parallel with a space in between. The first partition plate 21, the second frame plate 23, and the third frame plate 25 are erected between the second partition plate 24 and the connecting frame plate 27, and are parallel to each other in a posture orthogonal to the second partition plate 24 and the like. It is installed side by side. The second partition plate 24, the connecting frame plate 27, the second frame plate 23, and the third frame plate 25 constitute the first frame body 10A having a substantially square cylinder shape, and the first partition plate 21 constitutes the first frame body 10A. The inside of is divided (partitioned) into almost two equal parts. As a result, the partition member 1 becomes an intermediate form F2 in which two square cylindrical partition spaces S2 are adjacent to each other in the left-right direction (see FIG. 6).

<Folding process>
Next, as shown in FIG. 7, the user reversely folds the partition member 1 (first frame body 10A) in the intermediate form F2 along the hinge line 16. The user further advances the reverse folding, and folds the joint piece 20 and the second partition plate 24 by the hinge wire 16 by approximately 180 degrees (folding step). Then, as shown in FIG. 8, a part of the second wall 12 is folded back by the hinge line 16, and the first wall 11, the part excluding the part of the second wall 12, and the third wall 13 are separated by the cutting line 17. Will be done. .. Specifically, the second partition plate 24 and the joint piece 20 are folded back at the hinge wire 16, and the first partition plate 21, the first frame plate 22, the second frame plate 23, and the third wall 13 (third frame plate) are folded back. 25, the fourth frame plate 26) is separated by a cutting line 17. More specifically, the seam portion 17A connecting the fourth frame plate 26 is broken due to the folding back at the hinge wire 16, and the seam piece 20 is a back liner which is an adhesive surface with the second partition plate 24. It is folded back while breaking at the hinge wire 16 leaving 9C.

As shown in FIG. 8, when the folding process is completed, the second partition plate 24 folded back by the hinge wire 16 becomes a double partition wall 28 in which the front liners 9B are overlapped with each other. The pair of connecting frame plates 27 (first frame plate 22, fourth frame plate 26) bisected by the cutting line 17 face each other substantially in parallel with a space interposed therebetween. Have been placed. The first partition plate 21, the second frame plate 23, and the third frame plate 25 are each substantially bisected by a cutting line 17, and are erected between the double partition wall 28 and the pair of connecting frame plates 27. They are arranged side by side in parallel with each other in a posture orthogonal to the double partition wall 28 and the like. A pair of connecting frame plates 27, a pair of second frame plates 23, and a pair of third frame plates 25 constitute a pair of second frame bodies 10B in which the first frame body 10A is substantially bisected in the height direction. The double partition wall 28 and the pair of first partition plates 21 are formed in a cross shape to divide (partition) the inside of the pair of second frame bodies 10B into substantially four equal parts. As a result, the partition member 1 becomes a partition form F3 in which the four partition spaces S2 are formed in a grid pattern.

As a result, the partition member 1 having the partition form F3 is completed (see FIG. 8). In the above-mentioned assembly procedure of the partition member 1, the folding step is performed after the raising process is performed, but the procedure opposite to this, that is, the raising process may be performed after performing the folding process.

The user assembles the box body 40 with the top surface open (see FIG. 1), and accommodates the partition member 1 in the internal space S1 of the box body 40 (see FIG. 2). The user accommodates the product in each partition space S2 of the partition member 1. In addition, in FIGS. 1 and 2, the partition member 1 is housed in the box body 40 in a posture in which the hinge wire 16 is directed downward (upside down from FIG. 8), but the partition member 1 is not limited to this. The hinge wire 16 may be housed in the box body 40 in an upward posture (see FIG. 8). Further, depending on the size (dimensions) of the box body 40, the partition member 1 (see FIG. 6) having the intermediate form F2 may be housed in the box body 40 and used as a partition (not shown).

As shown in FIG. 2, in a state where the partition member 1 is housed in the box body 40, the partition member 1 (a pair of second frame bodies 10B (connecting frame plate 27, second frame plate 23, and third frame plate 25)). ) Is fitted into the peripheral wall 41 of the box body 40 without any gap, and the partition member 1 is immovably held in the internal space S1 of the box body 40. Further, the cross-shaped partition (double partition wall 28 and the pair of first partition plates 21) is connected (fixed) to a frame having a substantially square tube shape. Thereby, only by accommodating the partition member 1 in the box body 40, it is possible to configure a partition that restricts unnecessary movement of the product and firmly supports the product. In the partition member 1, the pair of second frame bodies 10B are connected to each other by the hinge wire 16, and the pair of first partition plates 21 are connected to the second frame body 10B. Even if it is not housed in the box body 40, it is possible to maintain the shape in which the four partition spaces S2 are arranged in a grid pattern.

As a result, the partition member 1 can be easily assembled in a short time as compared with the case where the tubular shape is manually assembled from the blank.

Further, in the partition member 1 according to the present embodiment, the first to second turn-back lines 14 to 15 are easier to break than the first to fourth turn-down curves 31 to 34. According to this configuration, when the partition member 1 having the folded form F1 by FFG or the like is manufactured, the blank 1A is relatively difficult to break on the first to fourth folding curves 31 to 34, so that the first to first blanks 1A are relatively difficult to break. 2 It is possible to properly fold the first wall 11 and the third wall 13 along the fold lines 14 to 15.

Further, in the partition member 1 according to the present embodiment, the notch portions 30 are formed corresponding to both ends of the first and second turnaround lines 14 to 15 (see FIG. 3 and the like). According to this configuration, the first to second folding lines 14 to 15 can be made shorter than the second to fourth folding curves 32 to 34 to reduce the strength (rigidity), and the first wall 11 and the first wall 11 and the first wall can be reduced. It is possible to easily concentrate the force of folding back the three walls 13 on the notch portion 30. As a result, when the partition member 1 having the folding form F1 is manufactured by the apparatus for pasting, the first wall 11 and the third wall 13 can be properly folded back at the first to second folding lines 14 to 15. can.

Further, according to the partition member 1 according to the present embodiment, since the hinge wire 16 formed on the joint piece 20 is a break line, the hinge wire 20 is split while the joint piece 20 is broken and widened. It can be folded back so as to straddle the second partition plate 24 which has been folded back at 16 to form a double wall (see FIGS. 7 and 8).

Further, according to the partition member 1 according to the present embodiment, the third wall 13 is not completely separated by the cutting line 17, but is connected by the seam portion 17A on the tip end side of the fourth frame plate 26 (FIG. FIG. (Refer to 3 etc.), when the partition member 1 having the folding form F1 is manufactured by the sticking processing device, the third wall 13 can be integrated and folded back at the second folding line 15.

Further, in the partition member 1 according to the present embodiment, the first wall 11 has a shape that tapers from the first partition plate 21 toward the joint piece 20, and the tip portion of the third wall 13 (fourth frame plate 26). Was also tapered (see Fig. 3 etc.). According to this configuration, even if the first wall 11 is folded back at the first folding line 14 and laminated on the second wall 12, the sticking deviation occurs in the height direction (the direction in which the first folding line 14 or the like extends). , The first partition plate 21 and the joint piece 20 can be prevented from protruding into either one of the height directions of the second wall 12 (second partition plate 24) (see FIGS. 4 and 5). Further, even if the third wall 13 is folded back at the second folding line 15 and laminated on the first wall 11 and the sticking deviation occurs in the height direction, the third wall 13 (fourth frame plate 26) is the first. It is possible to prevent the wall 11 (first frame plate 22) from sticking out to either one in the height direction. As a result, it is possible to suppress the occurrence of defective products due to misalignment.
