Description

  The present invention relates to a cutting apparatus that cuts and accumulates sheets from a continuous strip in which a predetermined pattern is repeatedly printed in the longitudinal direction, and a method for manufacturing a package.

  2. Description of the Related Art Conventionally, food packaging bodies displaying food names, raw material names, and the like have been manufactured by cutting a strip-shaped packaging material on which a desired pattern is repeatedly printed for each desired information.

  FIG. 9 is a diagram for explaining a process of cutting the transparent film F on which a desired pattern is repeatedly printed by a printing unit for each desired pattern in the conventional technique. The strip-shaped transparent film F is wound around the roller 100 after desired information is printed by the printing means. Then, the operator pulls the transparent film F from the roller 100 and winds it on the winding device 101. At this time, while visually recognizing the pattern P on the inner peripheral side transparent film F, the transparent film F is wound around the winding device 101 while being aligned so that the pattern P overlaps therewith. Thereby, the transparent film F wound up by the winding device 101 is wound in a state where the pattern P is overlapped from the inner peripheral side to the outer peripheral side of the winding device 101. For example, when the winding device 101 is rotated 50 times, the transparent film F wound up by the winding device 101 is cut in the short direction.

  FIG. 9B shows a stack 103 of a plurality of sheets obtained by cutting the transparent film F taken up by the take-up device 101 in the short direction. As described above, since the desired pattern P printed on the transparent film F is aligned so as to overlap each other when the sheet is wound around the winding device 101, the stacked body 103 of a plurality of sheets is provided for each sheet. The upper patterns P are stacked so as to overlap each other in the thickness direction of the sheet. Therefore, by simultaneously cutting a plurality of sheets according to the dividing line 104 shown in FIG. 9B so that the pattern P is positioned at the approximate center of each package, the pattern P is disposed at the approximate center of each. In addition, the same package can be manufactured simultaneously from a plurality of sheets.

  On the other hand, when the packaging material is opaque, unlike the case where the packaging material is transparent, when the packaging material is wound around the winding device 101 shown in FIG. Cannot be rolled up while aligning so that they overlap each other. Therefore, when the packaging material is opaque, the above-described method cannot perform the process of cutting for each pattern P simultaneously on a plurality of sheets. Therefore, when the packaging material is an opaque paper such as glassine paper, for example, as shown in FIG. 9C, a character string C indicating a food name or the like is printed densely, and characters for one package are printed. By dividing the row C into a size that includes a part of the row C, a food name or the like can be recognized from one package.

In addition, a technique is known in which the position of an edge extending in the longitudinal direction of the continuous band-shaped body is detected, and the position of the continuous band-shaped body in the short-side direction is controlled so that the edge is at a predetermined position and wound around the winding device. (Patent Document 1). According to such a technique, the position of the edge extending in the longitudinal direction of the continuous band-shaped body can be aligned and wound on the winding device, but when the desired pattern is printed on the continuous band-shaped body, the desired pattern Since the printing position of the belt may vary, the positional relationship between the edge of the continuous band and the pattern printed on the continuous band is not necessarily constant, and the positions of the edges of the continuous band are aligned. However, it is difficult to wind up the pattern printed on the continuous belt.

The position of the second pattern is detected, and the cutting position control means uses the cutting means so that the cutting position with respect to the position of the second pattern in the longitudinal direction of the continuous strip detected by the longitudinal position detection means becomes a predetermined position. The cutting timing or the conveying speed of the continuous belt-like body by the conveying means is controlled. Here, the first pattern is a straight line that exists at a predetermined position from the information pattern in the short direction of the continuous band and continuously extends in the longitudinal direction of the continuous band, and the second pattern is the continuous band. The object to be packaged by the packaging material is printed at a predetermined position from the information pattern in the longitudinal direction and corresponding to the predetermined repetition period of the information pattern in the longitudinal direction of the continuous strip.

The information pattern printed on the sheet cut from the continuous strip by the cutting means is the thickness of the sheet. There is an effect that can be integrated in a state of uniform along the direction.

  According to the method for manufacturing a package according to claim 10, a plurality of sheets are stacked using the cutting device according to claim 8 or 9 in the stacking process, and the stacked sheets are stacked in the cutting process. On the other hand, a cut for each information pattern is made simultaneously. Here, the plurality of sheets stacked using the cutting apparatus according to claim 8 or 9 are stacked in a state where the information patterns printed on the sheets are aligned along the thickness direction of the sheet. Therefore, by making the cuts for each information pattern on a plurality of sheets at the same time, the work efficiency can be improved and the packaging body can be reduced at a lower cost than when making the cuts for each information pattern for each sheet. There is an effect that it can be manufactured.

  According to the method for manufacturing a package according to claim 11, an information pattern including information on an object to be packaged by the package, and a predetermined position from the information pattern in the short and long directions of the continuous band-shaped body In the transporting process, the continuous belt-like body is drawn out in the longitudinal direction from the supply roller which winds and holds the continuous belt-like body having a predetermined pattern having a position display pattern printed in the longitudinal direction. And the position of the position display pattern in the short direction of the continuous strip conveyed by the conveying step is detected in the short direction position detecting step, and based on the detection position detected by the short direction position detecting step. In the supply roller moving step, the position display pattern in the short direction of the continuous belt-like body is positioned at a predetermined position with respect to the cutting means. The position of the supply roller is moved, and the position of the position display pattern in the longitudinal direction of the continuous strip supplied from the supply roller moved by the supply roller moving step is detected in the longitudinal position detecting step, In the cutting position control step, the cutting means is configured so that the cutting position by the cutting means is a predetermined position with respect to the position of the position display pattern in the longitudinal direction of the continuous belt-like body based on the detection position detected by the longitudinal position detection step. In the cutting process, the continuous strip is cut by the cutting timing controlled by the cutting position control step or the continuous strip transport speed controlled by the cutting position control step. Is cut in the short direction, so it was cut out from the continuous strip in the cutting process Over DOO, together have all the positions in the widthwise direction of the continuous strip on the basis of the position display pattern, positional relationship between the position display pattern with cutting edges is constant. Here, since the position display pattern is present at a predetermined position from the information pattern in the lateral direction and the longitudinal direction of the continuous strip, the plurality of sheets cut from the continuous strip in the cutting step, The position of the information pattern in the short direction is aligned, and the positional relationship between the information pattern and the cutting edge in the longitudinal direction of the continuous strip is constant. Therefore, in the stacking step of aligning the sides cut in the cutting step and stacking without changing the sheet position in the short direction of the continuous strip at the time of cutting, the sheet cut from the continuous strip is the sheet The information pattern printed thereon is accumulated in a state of being aligned along the thickness direction of the sheet. Therefore, a plurality of sheets accumulated in the stacking process can be cut simultaneously for each information pattern in the cutting process, compared with a case where a cut for each information pattern is made for each sheet. There is an effect that the working efficiency can be improved and the package can be manufactured at a low cost.

  According to the method for manufacturing a package according to claim 12, in addition to the effect produced by the method for manufacturing the package according to claim 11, the amount of deviation from the thickness direction of the plurality of sheets accumulated by the accumulation step in the inspection step. By visually observing the display pattern, variations in the cutting positions of the accumulated sheets are inspected, so that it is possible to produce a high-quality package. That is, in the cutting step, by cutting the continuous strip at a predetermined position with respect to the position of the position display pattern in the longitudinal direction of the continuous strip, and in the stacking step, by aligning the cut sides and stacking each sheet, The sheets are stacked in a state where the information pattern of each sheet is aligned along the thickness direction of the sheet. Therefore, when variation occurs in the cutting position cut in the cutting process, it is expected that the information pattern of each sheet is not aligned along the thickness direction of the sheet. When such a stack of sheets is simultaneously cut in the cutting process, the positional relationship between the information pattern and the cutting position varies between the sheets, and a highly uniform package cannot be obtained. Therefore, in the inspection process, for example, by removing in advance the sheet that has been determined that the cutting position is greatly shifted, it is possible to manufacture a highly accurate package that has no variation in the positional relationship between the information pattern and the cutting position. It is.

  According to the method for manufacturing a package according to claim 13, in addition to the effect produced by the method for manufacturing the package according to claim 12, the shift amount display pattern printed on the continuous band is the target cutting position. The first mark intersects diagonally, and the second mark passes through the intersection of the first mark and the target cutting position and intersects the target cutting position perpendicularly. The distance between the first mark and the second mark that can be viewed from the thickness direction at the cut side increases as the cut side moves away from the target cutting position. Therefore, there is an effect that the variation in the cutting position of each sheet accumulated in the accumulation process can be inspected with high accuracy based on the positional relationship between the first mark and the second mark.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. This cutting apparatus was obtained by cutting a continuous strip on which a predetermined pattern of figures and symbols was repeatedly printed in the longitudinal direction and the continuous strip by the cutting device for cutting in a short direction. The apparatus is provided with a stacking device or the like for stacking sheets, and can stack with a predetermined pattern on the sheet aligned in the thickness direction of the sheet. In addition, as a continuous strip, various packaging materials such as glassine paper, silicon paper, and film are used.

  FIG. 1 is a side sectional view showing a schematic configuration of a cutting apparatus 1 according to the present embodiment. The cutting device 1 includes a supply unit 2 that supplies the continuous strip W, a transport unit 4 that transports the continuous strip W supplied from the supply unit 2 to the main body unit 3 at a predetermined speed, and the transport unit 4. A short-direction position sensor 5 that detects a position in the short-side direction of the pattern of the continuous belt-like body W to be conveyed is provided.

  The supply unit 2 winds and holds a continuous strip W on which a predetermined pattern is pre-printed in a roll, and supports the supply roller 2a and is movable in the short direction of the continuous strip W A support base 2b and a hydraulic cylinder 2c for controlling the movement of the support base 2b. As the supply roller 2a rotates in the clockwise direction in FIG. 1, the continuous band W is supplied from the supply roller 2a to the conveying means 4.

  The main body 3 includes a longitudinal position sensor 6 that detects the position in the longitudinal direction of the pattern on the continuous band W conveyed by the conveying means 4, and the conveying means 4 on the downstream side of the longitudinal direction position sensor 6 in the conveying direction. The cutting device 7 that cuts the continuous belt-like body W transported in the short direction, and the sheet (rectangular thin body) S cut out from the continuous belt-like body W by the cutting device 7 is the longitudinal length of the continuous belt-like body W. A conveyor belt 8 that moves in the direction, a stacking roller 9 that stacks the sheets S transferred on the conveyor belt 8 every predetermined number of sheets, and a predetermined number of sheets S that are stacked on the stacking roller 9 from the stacking roller 9. A transfer unit 11 that receives and transports the sheet to the loading unit 10 and a control unit (not shown) that controls the operation of the entire cutting apparatus 1 are provided.

  The conveying means 4 is composed of a plurality of conveying rollers 4 a to 4 h provided between the supply roller 2 a and the cutting device 7 so as to be rotatable around the axis with respect to the main body 3. Among the plurality of transport rollers 4a to 4h, the transport roller 4h provided closest to the cutting device 7 rotates in the clockwise direction in FIG. 1 using the transport roller control motor 56 (see FIG. 3) as a power source. Thus, the continuous strip W is transported at a predetermined speed. Although not shown in the drawing, a paper pressing roller facing the transport roller 4h is provided, and the continuous belt W is held in the cutting device 7 while pressing the continuous belt W from above the transport roller 4h by the paper pressing roller. Send in.

  The cutting device 7 includes a lower blade 7a that is fixed to the main body 3 and an upper blade 7b that is pivotally supported by the main body 3 and rotates at a predetermined cycle around the axis. When the continuous strip W conveyed from the conveying roller 4h passes between the lower blade 7a and the upper blade 7b, the continuous blade W is continuously formed by the lower blade 7a and the upper blade 7b according to a predetermined rotation period of the upper blade 7b. The strip W is cut in the short direction.

  The conveyor belt 8 is a sheet S cut from the continuous band W by the cutting device 7 without changing the position of the continuous band W in the short direction (perpendicular to the paper surface in FIG. 1). The continuous belt-like body W is transported at the transport speed to the downstream side in the longitudinal direction (the right side in FIG. 1).

  The accumulation roller 9 is provided on the downstream side of the conveyor belt 8 and is rotationally driven around the axis with respect to the main body 3 by a power source such as a motor (not shown). Moreover, it has the nail | claw part 9a which can be opened and closed in the outer peripheral surface. The claw portion 9a of the stacking roller 9 opens and closes at the timing when the front end in the transport direction of one sheet S transported from the conveyor belt 8 reaches the stacking roller 9, so that the stacking roller 9 moves to the end of the sheet S. The sheet S gripped by rotating the portion around the axis is wound around the outer peripheral surface. Then, when the next sheet S is received, the claw portion 9a opens and closes again and is rotated around the axis so that the sheets S are wound around the outer peripheral surface thereof.

  Then, for example, when the stacking roller 9 rotates 5 times and the five sheets S are stacked on the outer peripheral surface of the stacking roller 9, the claw portion 9a opens and closes, so that the stacked five sheets S are It passes to the downstream transfer unit 11.

  The transfer unit 11 is provided with an endless annular chain belt 11a provided on both side surfaces of the main body 3 between the stacking roller 9 and the stacking unit 10, and the chain belt 11a. As the chain belt 11a rotates. A hook portion 11 b that circulates between the accumulation roller 9 and the stacking unit 10 is provided. The hook portion 11b is circulated between the stacking roller 9 and the stacking unit 10 by the chain belt 11a, so that the sheets S stacked by the stacking roller 9 are received at a predetermined cycle, and are placed at a predetermined position on the stacking unit 10. The sheets S are stacked on the stacking unit 10 by releasing the stacked sheets S. Specifically, for example, when the stacking roller 9 rotates five times to wind a stack of five sheets around the outer peripheral surface, the claw portion 9a is opened and closed at a predetermined timing, and the five sheets S are moved. It passes to the hook part 11b of the transfer unit 11. In this case, the accumulation roller 9 and the transfer unit 11 are interlocked so that the chain belt 11a of the transfer unit 11 travels slowly at a rotation cycle about 5 times the rotation cycle of the accumulation roller 9.

  FIG. 2 is a perspective view schematically showing a continuous band W from the supply unit 2 to the conveying roller 4h. As shown in FIG. 2, the continuous band W includes an information pattern Pi composed of a raw material name such as a food to be displayed on a package finally produced from the continuous band W and a production area, and a continuous band. A straight line extending continuously in the longitudinal direction of the body W, the first pattern P1 having a constant positional relationship with the information pattern Pi in the lateral direction of the continuous strip W, and the longitudinal direction of the continuous strip W The information pattern Pi is printed in correspondence with a predetermined repetition period of the information pattern Pi (for example, every three information patterns Pi along the longitudinal direction of the continuous strip W). And the second pattern P2 having a constant positional relationship is printed.

  The information pattern Pi, the first pattern P1, and the second pattern P2 are gravure-printed on a plain belt-shaped glassine paper or the like before the cutting process by the cutting apparatus 1. The printing apparatus that performs the gravure printing includes a plate cylinder on which a plate corresponding to the information pattern Pi, the first pattern P1, and the second pattern P2 is formed on the outer peripheral surface, and ink supplied to the outer peripheral surface of the plate cylinder. It consists of an ink pan to be stored, a doctor that scrapes off excess ink adhering to the outer peripheral surface of the plate cylinder, a pressure cylinder that presses the glassine paper against the plate cylinder, and a dryer that dries the ink on the surface of the glassine paper. . Printing on the belt-shaped glassine paper conveys the belt-shaped glassine paper in the longitudinal direction and presses the belt-shaped glassine paper against the plate cylinder by the impression cylinder when passing between the plate cylinder and the impression cylinder to transfer the ink to the band-shaped glassine paper. Is done. Therefore, on the plain belt-shaped glassine paper, the information pattern Pi, the first pattern P1, and the second pattern P2 corresponding to a predetermined plate formed on the plate cylinder are repeatedly printed along the longitudinal direction and continuously. The positional relationship among the information pattern Pi printed on the band W, the first pattern P1, and the second pattern P2 is always constant.

  In the supply unit 2, a support 2b that supports the supply roller 2a is installed on two rails 2d that are provided in parallel to the axis of the supply roller 2a. The lateral direction position sensor 5 reads the first pattern P1 on the downstream side in the transport direction of the supply roller 2a. A detection value indicating the position of the first pattern P1 detected by the lateral direction position sensor 5 is output to a CPU 51 (see FIG. 3) described later. Then, the CPU 51 controls the hydraulic actuator 2 (see FIG. 3) based on the detection value of the short direction position sensor 5 to operate the hydraulic cylinder 2c, and the support base 2b moves on the rail 2d by the hydraulic cylinder 2c. The position of the first pattern P1 with respect to the cutting device 7 in the short direction of the continuous band W is moved to a predetermined position.

  The first pattern P1 is a straight line continuously extending in the longitudinal direction of the continuous band W as described above, and the positional relationship with the information pattern Pi is always constant. Accordingly, the position of the supply roller 2a is controlled so that the position of the first pattern P1 in the short-side direction of the continuous band W is a predetermined position predetermined with respect to the cutting device 7, thereby being supplied from the supply roller 2a. The continuous strip W can be conveyed to the cutting device 7 while keeping the position of the information pattern Pi in the short direction of the continuous strip W relative to the cutting device 7 in a constant state.

  The longitudinal position sensor 6 is a sensor disposed in the vicinity of the conveying roller 4h and reads the second pattern P2. When detecting the second pattern P2, the longitudinal position sensor 6 outputs a signal to a CPU 51 (see FIG. 3) described later. The CPU 51 controls the conveyance roller control motor 56 (see FIG. 3) on the basis of the detection timing of the second pattern P2, so that the continuous band-shaped body is located at the position where the second pattern P2 exists in the longitudinal direction of the continuous band W. The rotational speed of the conveying roller 4h is controlled so that W is cut in the short direction.

  Specifically, when there is a delay in the timing at which the second pattern P2 passes the longitudinal position sensor 6, the continuous belt-like body is obtained by increasing the rotation speed of the conveying roller 4h provided in the vicinity of the cutting device 7. The conveyance speed of W is increased, and control is performed so that the upstream side of the continuous strip W is cut by the cutting device 7. In addition, when the timing at which the second pattern P2 passes through the longitudinal position sensor 6 is earlier than a predetermined timing, the transport speed of the continuous strip W so that the downstream side of the continuous strip W is cut by the cutting device 7. Reduce. In this way, control is performed so that the second pattern P2 passes between the lower blade 7a and the upper blade 7b at the timing when the cutting is performed between the lower blade 7a and the upper blade 7b. Thus, the continuous strip W is cut in the short direction at the position where the second pattern P2 exists in the longitudinal direction of the continuous strip W.

  The second pattern P2 is printed in correspondence with a predetermined repetition period of the information pattern Pi along the longitudinal direction of the continuous strip W as described above. In the longitudinal direction of the continuous strip W, the information pattern Pi The positional relationship of is constant. Therefore, by cutting the continuous strip W at the position where the second pattern P2 exists, the positional relationship between the cutting position cut by the cutting device 7 and the position of the information pattern Pi in the longitudinal direction of the continuous strip W is obtained. It can be constant.

  Returning to FIG. 1, the overall operation of the cutting apparatus 1 will be described. The cutting device 1 draws and conveys the continuous band W from the supply roller 2a in the longitudinal direction (conveying process), and determines the position of the first pattern P1 (see FIG. 2) in the short direction of the conveyed continuous band W. The position of the first pattern P1 in the short direction of the continuous band W is detected by the short direction position sensor 5 (short direction position detection step), and based on the detection position by the short direction position sensor 5, the cutting device 7, the position of the supply roller 2a in the short direction (perpendicular to the paper surface in FIG. 1) of the continuous strip W is moved (supply roller moving step) so as to be in a predetermined position with respect to 7, and from the moved supply roller 2a The position of the second pattern P2 in the longitudinal direction of the continuous strip W supplied is detected by the longitudinal position sensor 6 (longitudinal position detecting step), and based on the detection position by the longitudinal position sensor 6. And, with respect to the position of the second pattern P2 in the longitudinal direction of the continuous strip W, the conveying speed of the continuous strip W is controlled so that the cutting position by the cutting device 7 is a predetermined position (cutting position control step). At the controlled speed of transporting the continuous band, the continuous band W is cut in the short direction by the cutting device 7 (cutting step), and a plurality of sheets S cut from the continuous band W are cut. The stacked sides 10 are stacked and stacked in the stacked unit 10 without changing the sheet position in the short direction of the continuous strip W at the time of cutting (stacking step).

  FIG. 3 is a block diagram illustrating an outline of an electric circuit configuration of the cutting apparatus 1. A control device for controlling the cutting device 1 includes a microcomputer (hereinafter referred to as “CPU”) 51, a ROM 52 which is a memory storing various control programs executed by the CPU 51 and fixed value data, A RAM 53 that is a memory for temporarily storing data and the like is provided.

  The CPU 51, which is an arithmetic device, executes various processes in accordance with various control programs stored in advance in the ROM 52. The CPU 51 includes a hydraulic actuator 55 that is a drive source of the hydraulic cylinder 2c, a short-side position sensor 5 that detects the first pattern P1 of the continuous strip W, and a continuous strip W through the input / output port 50. A longitudinal position sensor 6 that detects the second pattern P2, a conveyance roller control motor 56 that controls the rotation speed of the conveyance roller 4h, a cutting actuator 57 that is a drive source of the upper blade 7b of the cutting device 7, and an accumulation roller The integrated roller control motor 58 as a drive source 9 and a transfer unit control motor 59 as a drive source of the transfer unit 11 are connected.

  Next, the conveyance control operation of the cutting apparatus 1 configured as described above will be described with reference to the flowchart of FIG. When the supply roller 2a holding the continuous strip W is attached to the supply unit 2 and a start switch (not shown) is pressed by the user, the transport roller 4h, the upper blade 7b of the cutting device 7 and the like (see FIG. 1) The conveyance control process shown in the flowchart of FIG. 4 is started while being rotated.

  In the transport control process, first, a signal from the lateral direction position sensor 5 is acquired (S1). Based on the signal from the short direction position sensor 5, it is determined whether or not there is a deviation in the detection position of the first pattern P1 (see FIG. 2) in the short direction of the continuous band W (S2). If there is no deviation in the detection position of the first pattern P1 (S2: No), the process proceeds to S4. If there is a deviation in the detection position of the first pattern P1 (S2: Yes), the detection position of the first pattern P1. The cylinder 2c (see FIG. 2) is operated by controlling the hydraulic actuator 55 in accordance with the amount of deviation, and the position of the first pattern P1 with respect to the cutting device 7 (see FIG. 1) is set to a predetermined position (S3).

  Subsequently, a detection signal of the second pattern P2 is acquired from the longitudinal position sensor 6 (S4). If there is no deviation in the timing of the detection signal of the second pattern P2 from the longitudinal position sensor 6 (S5: No), the process returns to the processing of S1, but the timing of the detection signal of the second pattern P2 from the longitudinal direction position sensor 6 If there is a deviation (S5: Yes), it can be determined that there is a deviation in the position of the second pattern P2 in the longitudinal direction of the continuous band W, so that the second pattern P2 The rotation speed of the conveyance roller 4h (see FIG. 1) is controlled by the conveyance roller control motor 56 according to the amount of detection timing deviation, and the conveyance speed of the continuous strip W is controlled (S6). In this way, the position of the second pattern P2 in the longitudinal direction of the continuous strip W is detected in the vicinity of the upstream side of the cutting device 7, and based on the detection timing, the continuous strip W at the position where the second pattern P2 exists. The conveyance speed is controlled so that is cut.

  With the conveyance control process shown in the flowchart of FIG. 4, the continuous strip W is conveyed with the short-side direction position with respect to the cutting device 7 aligned based on the first pattern P1, and the cutting device 7 at the position where the second pattern P2 exists. Is cut in the short direction. The sheet S obtained by being cut from the continuous band W by the cutting device 7 is cut without changing the sheet position in the short direction of the continuous band W at the time of cutting in the accumulation roller 9 (see FIG. 1). Since the sides cut by the apparatus 7 are aligned and accumulated in the thickness direction of the sheet, each of the accumulated sheets has its first pattern P1 and second pattern P2 aligned along the thickness direction of the sheet. Yes. Here, since the positional relationship among the information pattern Pi, the first pattern P1, and the second pattern P2 is always constant, each sheet is accumulated with its information pattern Pi aligned along the thickness direction of the sheet. Therefore, by using the cutting apparatus 1 of the present embodiment, even if the continuous strip W is made of an opaque packaging material, an integrated body in which the information pattern Pi is aligned in the thickness direction of the sheet is obtained. Obtainable.

  In the cutting apparatus 1 according to the first aspect, the process of S3 in FIG. 4 corresponds to the supply roller position control means, and the process of S6 in FIG. 4 corresponds to the cutting position control means.

  In the present embodiment, the cutting position control means (the process of S6 in FIG. 4) controls the conveyance speed of the continuous band W by the conveyance roller 4h, but the cutting blade 57b of the cutting device 7 is controlled by the cutting actuator 57. It is also possible to control the cutting position in the longitudinal direction of the continuous strip W by controlling the rotation speed and controlling the cutting timing in the cutting device 7.

  Next, an example of the method for manufacturing a package according to the present invention will be described. FIG. 5 is a process flow diagram of the present invention. The method for manufacturing a package of the present invention is a method for manufacturing a package by simultaneously making a predetermined cut into a plurality of sheets S accumulated by using the cutting apparatus 1 described above.

  First, in the cutting / accumulating step 70, a continuous strip W in which an information pattern Pi, a first pattern P1, a second pattern P2, and a displacement amount display pattern Pd, which will be described in detail later, are repeatedly printed in the longitudinal direction is formed. The sheet obtained from the continuous belt W is cut by cutting in the short direction using the cutting device 1. FIG. 6A is a view showing the sheets S accumulated by the cutting / stacking step 70. In the cutting / stacking step 70, by using the above-described cutting apparatus 1, the patterns printed on the sheets S are stacked in a state where the positions are aligned in the thickness direction of the sheets S. In the present embodiment, the continuous strip W is cut by the cutting apparatus 1 not every second pattern P2, but every other second pattern P2.

  Subsequently, in the inspection step 71, the variation in the cutting position in the sheets S stacked in the cutting / stacking step 70 is inspected. A predetermined pattern is printed on each sheet S by gravure printing. However, since ink penetrates to a predetermined depth in the thickness direction at the time of gravure printing, the cutting by the cutting device 7 causes the pattern on the continuous strip W to be formed. When crossed, the presence of the pattern can be visually observed from the thickness direction of the sheet S at the cut side.

  As shown in FIGS. 6A and 6B, the shift amount display pattern Pd is a plurality of straight lines arranged in a staircase pattern, and the first mark M1 that obliquely intersects the target cutting position; A second mark M2 passing through the intersection of the first mark M1 and the target cutting position and perpendicular to the target cutting position is parallel to the second mark M2 at both ends of the first mark M1. It has the 3rd mark M3 which is a straight line. Therefore, a part of the first mark M1, the second mark M2, and the third mark M3 can be seen from the thickness direction of the sheet S at the cut side cut across the misaligned display pattern Pd.

  Here, the “cutting position to be targeted” is a position to be cut that is determined based on the positional relationship with the second pattern P2, but in the present embodiment, it crosses the second pattern P2. A straight line extending in the short direction of the continuous strip W corresponds to that.

  FIG. 6B shows the relationship between the cutting positions 1 to 10 in the continuous band W and the shift amount display pattern Pd that is viewed from the thickness direction of the sheet S when cut at the cutting positions 1 to 10. It is a figure shown typically. As shown in FIG. 6B, when the continuous band W is cut at the cutting positions 2 to 9, the second mark M2 and the third mark M3 are visually observed from the thickness direction of the sheet S at the cut side. In addition, the first mark M1 corresponding to the cutting position is visually observed between the second mark M2 and the third mark M3. Therefore, by confirming the position of the first mark M1 between the second mark M2 and the third mark M3, the distance between the cutting edge that is the actual cutting position and the cutting position to be targeted is determined for each sheet. Can know.

  Further, for example, when the continuous band W is cut at the cutting positions 1 and 10 shown in FIG. 6B, the shift amount display pattern Pd is not cut, so the first mark M1 and the second mark Neither M2 nor the third mark M3 is visually observed from the thickness direction of the sheet S.

  As described above, since the cutting apparatus 1 stacks the sheets S with the cut sides aligned, in the stack of sheets S when the cut sides are far away from the target cutting position. The position of the information pattern Pi in the thickness direction is greatly deviated from the information pattern Pi of other sheets in the stack. When such a stack of sheets S is cut for each information pattern Pi in the sheet thickness direction in the subsequent cutting step 73, the positional relationship between the information pattern Pi and the cutting position is determined between the sheets S. As a result, the package cannot be obtained. Therefore, in the inspection step 71, the sheet S for which it is determined that the cutting position is greatly deviated can be manufactured in advance, for example, so that a highly accurate package without variation can be manufactured.

  Returning to FIG. In the cutting process 72 following the inspection process 71, the sheet is adjusted in accordance with the size of a punching machine 80 (see FIG. 7) for simultaneously cutting the stack of sheets S in the sheet thickness direction in the subsequent cutting process 73. Cut the S stack. In the cutting step 72, one end portion on which the first pattern P1 and the second pattern P2 that are not necessary for a package are printed is cut off from each sheet S.

  In a cutting process 73 subsequent to the cutting process 72, the stack of sheets S cut in a predetermined size in the cutting process 72 is cut for each information pattern Pi. FIG. 7 is a view for explaining the punching machine 80 used in the cutting step 73 and the package L that has been cut by the punching machine 80. As shown in the side view of the punching machine 80 in FIG. 7A, the punching machine 80 moves in the vertical direction with respect to the rectangular frame 81 on which the stack of sheets S is placed, and the rectangular frame 81. The press plate 82 is configured to press the stacked body of sheets S placed in the rectangular frame 81. FIG. 7B is a top view of the rectangular frame 81. When the sheet S is placed in the rectangular frame 81, one information pattern Pi of the sheet S is provided. The punching blades 81a are erected so as to surround each one. By pressing the stacked body of sheets S placed in the rectangular frame 81 with the press board 82, it is possible to simultaneously make incisions corresponding to the punching blades 81a for a plurality of sheets S.

  FIG.7 (c) is a figure which shows the package L in which the notch | incision process 73 was cut for every information pattern Pi. Here, the package L may be completely cut for each information pattern Pi in the cutting step 73. Further, as shown in FIG. 7C, each unit including one information pattern Pi is not completely cut, but is composed of a plurality of units partially connected to adjacent units. May be. In this way, for example, after a package body such as food is actually placed on the package L, the package L can be easily separated and used for each unit by an operator's hand.

  Further, the package L is not limited to completely wrapping the packaged body, but may be affixed to the packaged body, or may be an underlay of the packaged body.

  According to the method for manufacturing a package of the present invention, by accumulating a plurality of sheets S using the cutting device 1 in the cutting / stacking step 70, the information pattern Pi printed on the sheet S becomes the sheet S. Since they are accumulated in a state of being aligned along the thickness direction, cuts for each information pattern Pi can be made simultaneously for a plurality of sheets S, and cuts for each information pattern Pi are made for each sheet. Compared to the case, the working efficiency can be improved, and the package L can be manufactured at low cost.

  The present invention has been described above based on the embodiments. However, the present invention is not limited to the above-described embodiments, and various improvements and modifications can be easily made without departing from the spirit of the present invention. Can be inferred.

  For example, in the present embodiment, the first pattern P1 is a straight line extending in the longitudinal direction of the continuous strip W, but may be a dotted line extending in the longitudinal direction of the continuous strip W, for example. If the positional relationship between the first pattern P1 and the information pattern Pi is constant, the position of the supply roller 2a is controlled so that the position of the first pattern P1 is a predetermined position with respect to the cutting device 7, thereby providing a continuous belt-like body. This is because it is possible to align the information pattern Pi with respect to the cutting device 7 in the W lateral direction.

  In the present embodiment, the continuous strip W is cut in the short direction at the position of the second pattern P2, but any cutting position can be used as long as the cutting position is controlled based on the position of the second pattern P2. A position that is a predetermined distance away from the second pattern P2 may be the cutting position.

  Further, in the present embodiment, the first mark M1 of the shift amount display pattern Pd is a plurality of straight lines arranged in a staircase shape and intersects obliquely with respect to the target cutting position. As long as it intersects diagonally with respect to the target cutting position, it may be constituted by a straight line, for example. FIG. 8A is a diagram showing a modified example of the shift amount display pattern, and the first mark M1 is printed as a straight line that obliquely intersects the cutting position to be targeted. FIG. 8B is a diagram schematically showing the relationship between the cutting positions 1 to 5 of the continuous belt-like body W and the pattern that can be viewed from the sheet thickness direction when cut at the cutting positions 1 to 5. . As shown in FIG. 8B, also in the shift amount display pattern Pd ′ of this modified example, the second mark M2 and the third mark 3 from the thickness direction of the sheet S are the same as the shift amount display pattern Pd shown in FIG. The mark M3 is visually observed, and a part of the first mark M1 corresponding to the cutting position is visually observed between the second mark M2 and the third mark M3. In particular, in the shift amount display pattern Pd ′ of this modification, the first mark M1 is configured as a continuous straight line, and therefore the position of the first mark M1 visually observed in the thickness direction of the stack of sheets S is As shown in FIG. 8C, it becomes continuous, and in the inspection step 71, it is possible to inspect the variation in the cutting position of each stacked sheet with higher accuracy.

  Further, in this embodiment, in the cutting step 72 after the inspection step 71, the stack of sheets S is cut according to the size of the punching machine 80. However, the stack of sheets S is preliminarily cut out. If the cutting apparatus 1 is cut to fit the size of 80, the cutting step 72 is not necessarily provided.

  In this embodiment, the inspection process 71 is performed before the cutting process 72, but may be performed after the cutting process 72. At this time, the deviation amount display pattern Pd may be printed in advance at the position to be cut by the cutting step 72, and the variation in the cutting position may be inspected at the cut side cut by the cutting step 72.
