Description

[Technical field]

[0001] The present invention relates to a lined sheet manufacturing apparatus for forming lines on sheet material such as thick paper or corrugated cardboard. [Background technology]

[0002] Conventionally, a crease-containing blank sheet manufacturing device that combines a crease forming device and a rotary die cutter has been known as a device for manufacturing blank sheets that are used as materials for cardboard boxes and the like (see Patent Document 1). The crease forming device is a device that forms creases such as pressed creases and cut creases in sheet material. Here, the pressed creases and cut creases are both used as fold lines for folding the sheet material, and the pressed creases are formed by forming linear concave portions on the surface that becomes a valley when folded (convex portions on the other surface), and the cut creases are formed by forming cuts to a predetermined depth from the surface that becomes a peak when folded. The rotary die cutter is a device that cuts out the sheet material into a predetermined shape.

[0003] The lined blank sheet manufacturing device described in Patent Document 1 includes a creaser unit as a line forming device. The creaser unit includes a pair of rotating shafts arranged vertically in parallel to the sheet material and perpendicular to the conveying direction, and a plurality of creasers, each consisting of a disk-shaped member attached to one of the rotating shafts, arranged at intervals in the longitudinal direction of the rotating shaft. Although not specified in Patent Document 1, in a line forming device using such a creaser, a disk-shaped creaser is generally attached to one rotating shaft so as to face the creaser attached to the other rotating shaft (see Patent Document 2, for example). One of the opposing creasers has a convex outer periphery and the other has a concave outer periphery. The pair of creasers forms creases on the surface of the sheet material passing between them, the number of which is equal to the number of creasers. A rotary die cutter is formed by providing a cutting die on the outer periphery of a cylindrical rotating body whose rotating shaft is arranged perpendicular to the conveying direction of the sheet material, and cuts the creased sheet material into a predetermined shape to produce a lined blank sheet.

[0004] The creaser used in the crease forming device is not limited to the rotary type in which a disk rotates as described in Patent Documents 1 and 2. For example, Patent Document 3 describes a reciprocating creaser in which a first member with a convex rib and a second member with a groove extending in the same direction as the convex rib are arranged opposite each other, and one of the two members reciprocates toward the other. In this creaser, one member is pressed against the other member at a predetermined timing while the sheet material passes between the first and second members, thereby forming a crease at a predetermined position on the sheet material.

[0005] [Patent Document 1] JP 2020-138478 A [Patent Document 2] JP 2022-042544 A [Patent Document 3] JP 2019-064195 A Summary of the Invention [Problem to be solved by the invention]

[0006] If it is desired to change the position or number of the creases formed in the lined blank sheet, it is necessary to change the position or number of the creases. Also, if it is desired to change the shape of the creases, such as changing the depth of the creases or the direction of the concaves and convexes, or changing from an creased crease to a cut crease (or vice versa), it is necessary to replace the creaser with one of a different shape or one for cutting creases. However, with the device described in Patent Document 1, it is not easy to change the position or number of the creases or replace them with different types.

[0007] The problem to be solved by the present invention is to provide a lined sheet manufacturing apparatus that can easily change the position, number, shape, type, etc. of the lines formed on a lined sheet. [Means for solving the problem]

[0008] The lined sheet manufacturing apparatus according to the present invention, which solves the above problems, is as follows: a) a housing having a unit mounting portion; b) a crease forming unit that is removably attached to the unit attachment portion and has a crease forming member; c) a drive section provided in the housing and connected directly or indirectly to the creasing member when the creasing unit is attached to the unit attachment section, for driving the creasing member; The present invention is characterized by comprising:

[0009] The lined sheet manufacturing apparatus according to the present invention is not limited to blank sheets, but may also be used for manufacturing lined sheets that are not cut out.

[0010] In the lined sheet manufacturing apparatus according to the present invention, the line forming unit includes a line forming member. The line forming member may be a rotary type as described in Patent Documents 1 and 2, or a reciprocating type as described in Patent Document 3. The line forming member is not limited to those that form pressed creases, but may also be a member that forms cut creases, perforated creases (lines that are made of perforations and can be cut), lead creases (lines that have dashed lines and are not intended to be cut), or the like.

[0011] When the creasing unit is attached to the unit attachment section, a drive section provided in the housing is directly or indirectly connected to the creasing member. This drives the creasing member. For example, if the creasing member is a rotary type, the drive section imparts a rotational motion to the creasing member. If the creasing member is a reciprocating type, the drive section imparts a reciprocating motion to the creasing member.

[0012] According to the lined sheet manufacturing apparatus of the present invention, the line forming unit can be removably attached to the unit mounting section, so that by preparing multiple types of line forming units differing in the position, number, shape, type, etc. of the line forming members, the position, number, shape, type, etc. of the line formed on the lined sheet to be produced can be easily changed simply by replacing the line forming unit attached to the unit mounting section.

[0013] The lined sheet manufacturing apparatus according to the present invention may further include a rotary die cutter for cutting out a sheet-like object having lines formed thereon by the line forming member into a predetermined shape, thereby obtaining a lined sheet having a desired shape.

[0014] In the lined sheet manufacturing apparatus according to the present invention, the housing may include a plurality of the unit mounting portions.

[0015] With a configuration having multiple unit mounting sections like this, the position at which the line forming unit is mounted or the number of line forming units mounted can be changed to change the position and number of lines formed on the target object.

[0016] In the configuration including the plurality of unit mounting portions, The drive unit can be configured to include a first drive unit that imparts a rotational motion to a line forming member of a line forming unit mounted to a first unit mounting portion, which is one of the plurality of unit mounting portions, and a second drive unit that imparts a reciprocating motion to a line forming member of a line forming unit mounted to a second unit mounting portion, which is another of the plurality of unit mounting portions.

[0017] In such a configuration with a first drive section and a second drive section, a creasing unit having a rotary creasing member is attached to the first unit attachment section, and a creasing unit attachment section having a reciprocating creasing member is attached to the second unit attachment section, meaning that both rotary and reciprocating creasing members can be used.

[0018] In the lined sheet manufacturing apparatus according to the present invention, the unit mounting portion is capable of mounting the line forming unit in both a first orientation and a second orientation that is inverted from the first orientation, The crease forming unit includes a crease forming member having two members arranged above and below, and when the crease forming unit is attached in the first orientation, one of the two members is directly or indirectly connected to the drive unit, and when the crease forming unit is attached in the second orientation, the other of the two members is directly or indirectly connected to the drive unit. The following configuration can be adopted.

[0019] In a lined sheet manufacturing apparatus having such a configuration, the vertical positions of the two members constituting the line forming member can be changed simply by flipping the line forming unit upside down and mounting it on the unit mounting part, which makes it possible to switch, for example, the side of the lined sheet on which the depressions for the pressed creases or the notches for the cut creases are formed from one side to the other. Effect of the Invention

[0020] The lined sheet manufacturing apparatus according to the present invention makes it possible to easily change the position, number, shape, type, etc. of the lines formed on the lined sheet. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0022] An embodiment of a ruled sheet manufacturing apparatus according to the present invention will be described with reference to Figs.

[0023] As shown in Fig. 1, the lined sheet manufacturing apparatus 1 of this embodiment has a line forming section (lined sheet manufacturing apparatus in the narrow sense) 10 and a rotary die cutter section 20. The line forming section 10 and the rotary die cutter section 20 are arranged side by side in the direction in which the sheet-like object S is transported (direction from right to left in Fig. 1), and of them, the line forming section 10 is located upstream in the transport direction (to the right in Fig. 1) of the rotary die cutter section 20. Hereinafter, the downstream side in the transport direction (the left side in Figs. 1 and 2) will be referred to as the "front", the upstream side (the right side in Figs. 1 and 2) as the "rear", the left side (the near side in Figs. 1 and 2) as viewed from the rear to the front will be referred to as the "left", and the right side (the far side in Figs. 1 and 2) as the "right".

[0024] Fig. 2 shows an external perspective view of the ruled line forming section 10. Ruled line forming section 10 has a housing 11, a first unit mounting section 121 and a second unit mounting section 122 provided in the housing 11, a first ruled line forming unit 131 and a second ruled line forming unit 132, and a first drive section 181 and a second drive section 182 provided in the housing 11. Fig. 2 shows a state in which an upper cover 110 provided on the upper surface of the housing 11 is opened. Figs. 1 and 2 also show a state in which the first ruled line forming unit 131 is mounted to the first unit mounting section 121, and the second ruled line forming unit 132 is mounted to the second unit mounting section 122.

[0025] First creasing unit 131 is removably attached to first unit attachment part 121, and second creasing unit 132 is removably attached to second unit attachment part 122. Fig. 3 shows the first creasing unit 131 removed from first unit attachment part 121, and Fig. 4 shows the second creasing unit 132 removed from second unit attachment part 122. First creasing unit 131 is inserted into first unit attachment part 121 from opening 111 provided on the left side surface of housing 11 (Fig. 3). Second creasing unit 132 is inserted into second unit attachment part 122 from above with top lid 110 of housing 11 open (Fig. 4).

[0026] In this embodiment, the first unit mounting portion 121 is disposed on the front side and the second unit mounting portion 122 is disposed on the rear side, but they may be disposed in reverse.

[0027] A transport mechanism 112 consisting of a pair of rollers is disposed behind the second unit mounting part 122 in the housing 11 and between the second unit mounting part 122 and the first unit mounting part 121. The transport mechanism 112 transports the sheet-like object S in the transport direction.

[0028] The configuration of first creasing unit 131 will be described below. Fig. 5 is a perspective view showing the inside of first creasing unit 131 with the front and rear outer plates omitted, and Fig. 6 is a rear view of the inside of first creasing unit 131 as seen from the rear with the front and rear outer plates omitted. In Fig. 6, the outer plates on both the left and right sides are also omitted. As shown in Fig. 5, the left outer plate is provided with a grip (handle) 1311 that a user grips when inserting or removing first creasing unit 131 into or from first unit attachment part 121.

[0029] The first ruled line forming unit 131 has a first rotating shaft 1421 and a second rotating shaft 1422, a first rotary ruled line forming member 1411 attached to the first rotating shaft 1421, and a second rotary ruled line forming member 1412 attached to the second rotating shaft 1422. The first rotary shaft 1421 and the second rotating shaft 1422 both extend left and right and are arranged side by side up and down. The first rotary ruled line forming member 1411 is a cylindrical drum having a protruding strip 14111 that runs around the outer periphery of the drum. The second rotary ruled line forming member 1412 is a cylindrical drum having a recessed groove 14121 that runs around the outer periphery of the drum, facing the protruding strip 14111 of the first rotary ruled line forming member 1411. The first rotary line forming member 1411 and the second rotary line forming member 1412 combine to form a pair of rotary line forming members 141. The rotary line forming member 141 is a line forming member that forms an imprinted line extending in the front-rear direction on the sheet-like object S.

[0030] A disk-shaped first rotating plate 1431 is provided on the right end of the first rotating shaft 1421 with its plate surface facing perpendicularly to the first rotating shaft 1421. Similarly, a disk-shaped second rotating plate 1432 is provided on the right end of the second rotating shaft 1422. The outer circumferential surfaces of the first rotating plate 1431 and the second rotating plate 1432 are in contact with each other.

[0031] First drive unit 181 (FIG. 1) has a rotating plate 1811 inside a housing (note that first drive unit 181 is not included in first ruling unit 131). Rotating plate 1811 rotates when the rotation of a motor is transmitted via a pulley and a belt (neither of which are shown).

[0032] The first rotating plate 1431 and the second rotating plate 1432 of the first creasing unit 131 are provided at positions such that when the first creasing unit 131 is mounted on the first unit mounting section 121 with the first rotary creasing member 1411 on the upper side, the plate surface of the first rotating plate 1431 abuts (connects) with the plate surface of the rotating plate 1811 of the first driving section 181 (see Figs. 6 and 7(a)), and when the second rotary creasing member 1412 is mounted on the upper side, the plate surface of the second rotating plate 1432 abuts (connects) with the plate surface of the rotating plate 1811 (see Figs. 8 and 7(b)). As a result, the one of the first rotating plate 1431 and the second rotating plate 1432 that abuts with the plate surface of the rotating plate 1811 of the first driving section 181 rotates by transmitting the rotation of the first driving section 181. Since the outer peripheral surfaces of the first rotating plate 1431 and the second rotating plate 1432 are in contact with each other, the one of the first rotating plate 1431 and the second rotating plate 1432 that is not in contact with the rotating plate 1811 of the first driving unit 181 rotates in the opposite direction to the other rotating plate.

[0033] In this way, regardless of whether first creasing unit 131 is attached to first unit attachment part 121 in the upside-down direction, first rotating plate 1431 and second rotating plate 1432 rotate in opposite directions to each other, thereby driving rotary creasing member 141. Turning first creasing unit 131 upside-down corresponds to swapping the positions of ridges 14111 and recessed grooves 14121.

[0034] The first creasing unit 131 further has a creasing member moving mechanism 144 for changing the axial position of the rotary creasing member 141. The creasing member moving mechanism 144 has two screw shafts 1441 arranged to sandwich the first rotating shaft 1421 and the second rotating shaft 1422 from above and below, a drum gripping portion 1442 arranged on each screw shaft 1441, and a rotation mechanism 1443 for synchronously rotating the two screw shafts 1441. One drum gripping portion 1442 is provided for each of the first rotary creasing member 1411 and the second rotary creasing member 1412, which grips the drums in the axial direction and has an insertion hole with a female thread cut on the inner surface. 5 and 6, and the drum gripper 1442 on the second rotary ruled line forming member 1412 side has an insertion hole inserted into the lower screw shaft 1441. The rotation mechanism 1443 has a stepping motor 14431 connected to one of the screw shafts, pulleys 14432 provided at one end of both screw shafts, and a belt 14433 hung around the two pulleys 14432. When the stepping motor 14431 rotates a predetermined angle, one screw shaft 1441 rotates the same angle and, via the pulley 14432 and the belt 14433, the other screw shaft 1441 also rotates the same angle, causing the drum gripping portion 1442 and the first rotary ruled line forming member 1411 and second rotary ruled line forming member 1412 gripped thereby to move a predetermined distance in the axial direction. A ruled line forming member moving mechanism 144 is provided on each of the two pairs of rotary ruled line forming members 141.

[0035] Four sheet holders 145 are provided between the two first rotary ruled line forming members 1411 on the first rotating shaft 1421, and between the two second rotary ruled line forming members 1412 on the second rotating shaft 1422. Each sheet holder 145 is formed by providing a through hole in the center of a disk through which the first rotating shaft 1421 or the second rotating shaft 1422 is inserted. The four sheet holders 145 provided on the first rotating shaft 1421 are positioned opposite the four sheet holders 145 provided on the second rotating shaft 1422. The sheet-like object S passes between the opposing sheet holders 145 in this manner. Compression springs 146 are provided between first rotary ruled line forming member 1411 or second rotary ruled line forming member 1412 and the adjacent sheet holders 145, and between adjacent sheet holders 145, and each sheet holder 145 is positioned where the repulsive forces of compression springs 146 are balanced. When rotary ruled line forming member 141 is moved by ruled line forming member moving mechanism 144, sheet holders 145 also move accordingly.

[0036] In the first ruled line forming unit 131 shown here, two pairs of rotary ruled line forming members 141 are arranged spaced apart in the axial direction as described above, but a ruled line forming unit provided with one pair or three or more pairs of rotary ruled line forming members 141 may be used. Also, the rotary ruled line forming member 141 shown here forms a pressed line on the object S using a convex rib 14111 and a concave groove 14121 formed around the outer circumferential surface of the drum, but instead, as shown in Figure 9, a rotary ruled line forming member 141A may be used that is composed of a first rotary ruled line forming member 1411A having a convex rib 14111A extending in the axial direction (left-right direction) of the drum and a second rotary ruled line forming member 1412A having a concave groove 14121A extending in the same direction. Also, instead of a pressed line, a known rotary ruled line forming member for forming a cut line, a perforated line, or a lead line may be provided. For example, when forming cut lines on the target object S, the outer circumferential surface of one of the drums of the first rotary type cut line forming member 1411 and the second rotary type cut line forming member 1412 is provided with a cutting blade that makes one revolution around the outer circumferential surface.

[0037] As described above, by preparing multiple first line forming units 131 having different numbers and types of rotary line forming members, and then replacing the first line forming unit 131 attached to the first unit mounting portion 121, the number, shape, type, etc. of the lines formed on the target object S can be changed.

[0038] Furthermore, since the positions of the convex ridges 14111 and the concave grooves 14121 can be swapped by inverting the first line forming unit 131 upside down and mounting it on the first unit mounting part 121 as described above, it is possible to change the shape of the lines by reversing the orientation of the convex and concave portions formed on the sheet-like object S between the front and back using the same first line forming unit 131. When forming cut lines instead of pressed lines, the surface of the object S on which the cuts are formed can be reversed between the front and back using a similar method.

[0039] In the first ruled line forming unit 131 shown here, the position of the rotary ruled line forming member 141 is moved using ruled line forming member moving mechanism 144, but instead, a plurality of first ruled line forming units 131 with different positions of the rotary ruled line forming member 141 may be used. In this case, the position of the ruled line formed on the target object S can be changed by replacing the first ruled line forming unit 131 attached to the first unit attachment part 121.

[0040] Next, the configuration of the second scoring unit 132 will be described. Fig. 10 is a perspective view of the second scoring unit 132 as seen from the front, Fig. 11(a) is a side view as seen from the left, and Fig. 11(b) is a front view. The second scoring unit 132 has a reciprocating scoring member 151 in which a flat first reciprocating scoring member 1511 and a flat second reciprocating scoring member 1512 are arranged so that one end face faces each other. Of the opposing end faces, the end face of the first reciprocating scoring member 1511 has a single convex strip 15111 extending left and right, and the end face of the second reciprocating scoring member 1512 has a single concave groove 15121 extending left and right. This reciprocating scoring member 151 is a scoring member that forms pressed scores extending left and right on the sheet-like target object S.

[0041] The first reciprocating ruled line forming member 1511 and the second reciprocating ruled line forming member 1512 are each provided with a through hole penetrating in the up-down direction near both the left and right ends, and one rod 152 is inserted through each of the left and right through holes, spanning from the first reciprocating ruled line forming member 1511 to the second reciprocating ruled line forming member 1512. Both the left and right rods 152 are provided with stoppers 153 at both the top and bottom ends. The first reciprocating ruled line forming member 1511 and the second reciprocating ruled line forming member 1512 can be separated from each other until they abut against the stopper 153, but they cannot be separated further apart than when they abut against the stopper 153. Furthermore, compression springs 154 are provided in the portions of the left and right rods 152 between the first reciprocating ruled line forming member 1511 and the second reciprocating ruled line forming member 1512. After applying an external force to bring the first reciprocating line forming member 1511 and the second reciprocating line forming member 1512 closer together, when the force is released, the repulsive force of the compression spring 154 causes the first reciprocating line forming member 1511 and the second reciprocating line forming member 1512 to move apart.

[0042] 10 and 11, the first reciprocating line forming member 1511 is drawn on the lower side and the second reciprocating line forming member 1512 is drawn on the upper side, but the second line forming unit 132 can be attached upside down to the second unit attachment part 122. That is, as shown in Fig. 12, the first reciprocating line forming member 1511 may be placed on the upper side and the second reciprocating line forming member 1512 on the lower side. The first reciprocating line forming member 1511 and the second reciprocating line forming member 1512 have two stepped cuts 155 on both the left and right ends of the end faces that become the lower ends when placed on the lower side. The aforementioned stoppers 153 are placed in the cuts 1551 near the left and right ends of these two cuts. On the other hand, when the second line forming unit 132 is attached to the second unit mounting portion 122, the eccentric cam 1821 of the second drive portion 182 described below abuts (connects) with the left and right inner notches 1552 of the first reciprocating line forming member 1511 and the second reciprocating line forming member 1512 that are located on the lower side.

[0043] The eccentric cam 1821 is housed in the second unit mounting portion 122 of the housing 11 and is eccentrically attached to both ends of a rotating shaft 1822 that extends left and right. The rotating shaft 1822 is rotated by a motor (not shown), and the eccentric cam 1821 also rotates accordingly. The notches 1552 abut so as to rest on the side surface of the eccentric cam 1821. As a result, the lower of the first reciprocating ruled line forming member 1511 and the second reciprocating ruled line forming member 1512 reciprocates up and down as the eccentric cam 1821 rotates.

[0044] A presser 156 is detachably attached to the housing 11. When the reciprocating line forming member 151 is attached to the second unit attachment section 122, the presser 156 presses down the upper end of the upper one of the first reciprocating line forming member 1511 and the second reciprocating line forming member 1512 from above. When the reciprocating line forming member 151 is removed from the second unit attachment section 122, the presser 156 is removed from the housing 11. The presser 156 prevents the entire reciprocating line forming member 151 from rising when it is pushed up by the action of the eccentric cam 1821, thereby bringing the first reciprocating line forming member 1511 and the second reciprocating line forming member 1512 closer to each other.

[0045] With the above-described configurations of reciprocating line forming member 151, second drive section 182, and presser 156, when second line forming unit 132 is attached to second unit attachment section 122 in either the upside down or upside down orientation, reciprocating line forming member 142 can be driven so that the lower of first reciprocating line forming member 1511 and second reciprocating line forming member 1512 reciprocates. Turning second line forming unit 132 upside down is equivalent to swapping the positions of ridges 15111 and recessed grooves 15121.

[0046] The first reciprocating ruled line forming member 1511 and the second reciprocating ruled line forming member 1512 are each provided with a grip (handle) 1321. The grip 1321 is for the user to grip when inserting or removing the reciprocating ruled line forming member 151 into or from the second unit mounting part 122. Each grip 1321 has a shape obtained by bending a plate material into a crank shape, and is provided with a hole 1322 through which the user's finger passes. By bending the plate material of the grip 1321 in this way, it is possible to prevent the grip 1321, which is located on the lower side when the reciprocating ruled line forming member 151 is mounted on the second unit mounting part 122, from interfering with the rotation shaft 1822 of the second drive part 182.

[0047] The second ruled line forming unit 132 shown here uses a reciprocating ruled line forming member 151 having a set of convex stripes 15111 and concave grooves 15121 extending in the left-right direction, but a reciprocating ruled line forming member having multiple sets of such convex stripes and concave grooves in the front-rear direction may be used, or a reciprocating ruled line forming member for forming cut lines, perforation lines, and lead lines may be used. In this way, by preparing multiple second ruled line forming units 132 having different numbers and types of reciprocating ruled line forming members and then replacing the second ruled line forming unit 132 attached to the second unit attachment part 122, the number, shape, type, etc. of the ruled lines formed on the target object S can be changed.

[0048] Furthermore, since the positions of the convex ridges 15111 and the concave grooves 15121 can be swapped by mounting the second creasing unit 132 upside down as described above on the second unit mounting part 122, it is possible to reverse the orientation of the concaves and convexes formed on the sheet-like target object S between the front and back using the same second creasing unit 132. The same applies when forming cut lines.

[0049] As shown in Fig. 1, the rotary die cutter unit 20 has a cylindrical die cylinder 21 and an anvil cylinder 22 arranged vertically facing each other with their rotation axes in the left-right direction, and a die plate 23 wrapped around the outer circumferential surface of the die cylinder 21. A cutting blade 231 is formed on the surface of the die plate 23. Since the die cylinder 21 is made of steel and the die plate 23 is made of a flexible magnetic material, the die plate 23 can be held on the outer circumferential surface of the die cylinder 21 by magnetic force. Furthermore, the rotary die cutter unit 20 has a drive unit (not shown) that rotates the die cylinder 21 and the anvil cylinder 22 in opposite directions to each other.

[0050] The lined sheet manufacturing apparatus 1 of this embodiment further has a control unit (not shown) that controls the synchronous operation of drive unit 18 of line forming unit 10 and drive unit of rotary die cutter unit 20. This controls the phase of the rotational motion of rotary line forming member 141 and reciprocating motion of reciprocating line forming member 151 in line forming unit 10, and the rotational motion of die cylinder 21 and anvil cylinder 22 in rotary die cutter unit 20, and aligns the positions where lines are formed in sheet-like object S and the positions where cutouts are made to predetermined positions.

[0051] When using the lined sheet manufacturing apparatus 1 of this embodiment, the first line forming unit 131 is attached to the first unit mounting section 121, and the second line forming unit 132 is attached to the second unit mounting section 122, as described above. Then, as shown in FIG. 1, the sheet-like object S is introduced into the transport mechanism 112 from the rear. As a result, the object S is first supplied between the first reciprocating line forming member 1511 and the second reciprocating line forming member 1512 of the second line forming unit 132. Then, when the first reciprocating line forming member 1511 and the second reciprocating line forming member 1512 are brought closest to each other by the reciprocating motion, a line (an imprinted line extending in the left-right direction in the above example) is formed on the object S. The object S is further transported between the first rotary line forming member 1411 and the second rotary line forming member 1412 of the first line forming unit 131, and a line (an imprinted line extending in the front-rear direction in the above example) is formed. The object S is further transported between the die cylinder 21 and the anvil cylinder 22 of the rotary die cutter unit 20 and punched out into a predetermined shape.

[0052] As described above, the ruled line forming units (first ruled line forming unit 131, second ruled line forming unit 132) mounted on the unit mounting parts (first unit mounting part 121, second unit mounting part 122) can be changed to units with different positions, numbers, shapes, types, etc. of ruled line forming members, or the same ruled line forming unit can be inverted upside down. This makes it possible to easily change the positions, numbers, shapes, types, etc. of the ruled lines formed on the target object S.

[0053] The present invention is not limited to the above embodiment, and various modifications are possible. For example, the ruled sheet manufacturing apparatus 1 of the above embodiment includes one each of a first unit mounting section 121 for mounting a first ruled line forming unit 131 having a rotary ruled line forming member 141 and a second unit mounting section 122 for mounting a second ruled line forming unit 132 having a reciprocating ruled line forming member 151, but it may include only one of the first unit mounting section 121 and the second unit mounting section 122. Also, it may include a plurality of either one or both of the first unit mounting section 121 and the second unit mounting section 122. When the second unit mounting section 122 is omitted, the rotary ruled line forming member 141, which is the ruled line forming member arranged at the rearmost position of the ruled sheet manufacturing apparatus, also has the function of transporting the target object S, so that the transport mechanism 112 may be omitted.

[0054] FIG. 13 shows an example in which three second unit mounting parts 122A, 122B, and 122C, each having the same configuration as second unit mounting part 122 in the above embodiment, are arranged side by side in the conveying direction of object S. Here, the number of second unit mounting parts is three, but it may be two or four or more. These multiple second unit mounting parts may be fitted with second line forming units that differ from each other in the position of the line forming member, the number of convex stripes, the shape, and the type, or the like, or may be fitted with second line forming units having the same type of line forming member. When different line forming units are fitted, lines of different shapes can be formed simultaneously on object S, and when the same type of line forming unit is fitted, multiple lines of the same shape can be formed on object S. Also, it is not essential to fit second line forming units to all of the multiple second unit mounting parts, and it is also possible to set the position, interval, etc. of the line to be formed on object S by fitting second line forming units to only some of the second unit mounting parts.

[0055] The crease forming unit can also be configured so that it can be mounted on the unit mounting section by being reversed from left to right. For example, crease forming unit 131A shown in Fig. 14 is a modification of first crease forming unit 131 of the above embodiment, in which first rotating plate 1431 and second rotating plate 1432 are provided on both ends of first rotating shaft 141 and second rotating shaft 142, respectively. With this crease forming unit 131A, when the first rotating plate 1431 is on the upper side in the vertical direction, either one of the first rotating plates 1431 (located at the back side of first unit mounting section 121) abuts against rotating plate 1811 of rotation mechanism 181 when crease forming unit 131A is mounted on first unit mounting section 121 in either the left or right direction. Similarly, when the second rotating plate 1432 is on the upper side, either one of the second rotating plates 1432 abuts against rotating plate 1811 of rotation mechanism 181. Therefore, the crease forming member can be driven regardless of whether the crease forming unit is attached in the left or right direction.

[0056] 14 shows an example in which two pairs of creasing line forming members having the same configuration (both rotary creasing line forming members 141 that form pressed lines) are arranged on the left and right, but two pairs of creasing line forming members having different configurations (for example, a rotary creasing line forming member that forms pressed lines and a rotary creasing line forming member that forms perforated lines) may also be arranged on the left and right. With this configuration, the creasing line forming units can be mounted on the unit mounting part with the left and right reversed, thereby reversing the type of creasing line formed on the target object.

[0057] Although the lined sheet manufacturing apparatus 1 of the above embodiment has the line forming section 10 and the rotary die cutter section 20, the line forming section 10 alone may be used as the lined sheet manufacturing apparatus without providing the rotary die cutter section 20.
