As a result, a package (packaging body set 501) in which six packaging bodies 500 are connected to the left and right is formed. The formed package body set 501 is sent to the rear of the package body forming line 90.

  Next, the direction of the package set 501 is detected by the meandering detection sensors 11 and 11. Here, when the control device 5 determines from the detection results of the meander detection sensors 11 and 11 that the direction of the package set 501 does not match the direction of the package formation line 90 (meandering). The upper roller 13 on the opposite side of the meandering side is driven downward. The upper roller 13 sandwiches the opposite side of the meandering side in the package set 501 with the opposing lower roller 12.

  Thereby, the direction of the package set 501 is gradually bent to the side opposite to the meandering side. When the control device 5 determines that the orientation of the package set 501 is the same as the orientation of the production line 90 (when the meander is corrected), the control device 5 drives the upper roller 13 upward to restore the original position. Return to.

  Next, after the left and right ends of each package 500 are divided by the slitters 93 and 93, the package set 501 is divided by the rotary cutters 94 and 94 so that the front end of each package 500 is the front of each package 500. Divided from the rear end. Thereby, the package body set 501 is separated into six package bodies 500. Each separated package 500 is discharged to the storage table 3.

  At this time, the package 500 is sorted. When the control device 5 determines from the detection result of the sorting camera 16 that the supply position of the packaged sheet 152a is deviated from the predetermined position, the package set 501 including the packaged sheet 152a is moved to the rotary cutter 94. , 94, the lid 172 is driven to open and the opening 171 is opened immediately before passing through. As a result, the package 500 (defective product) including the packaged sheet 152a deviated from the predetermined position is accommodated in the accommodating space 17S of the collection unit 17.

  The package 500 is continuously manufactured by the procedure described above. And in the sheet packaging machine 1 of this Embodiment, as shown to Fig.4 (a)-FIG.4 (c), without using a chute | shooting, the to-be-packaged sheet 152a is placed between the packaging materials 102a and 102a. Direct supply. For this reason, the sheet packaging machine 1 of this Embodiment can supply the to-be-packaged sheet 152a between the packaging materials 102a and 102a even when the to-be-packaged sheet raw fabric 152 is wet. Therefore, the sheet packaging machine 1 of this Embodiment can improve the supply performance of the to-be-packaged sheet 152a.

  Moreover, the sheet packaging machine 1 of this Embodiment is cut | disconnected in the state which clamped the raw material 152 to be packaged between the packaging materials 102a and 102a. For this reason, the packaging sheet 152a is sandwiched between the packaging materials 102a and 120a immediately after the formation. Therefore, the position of the packaged sheet 152a is not greatly shifted until it is completely sandwiched between the packaging materials 102a and 102a. Therefore, the sheet packaging machine 1 of this Embodiment can suppress the quality fall of the package 500. FIG.

  In addition, in the sheet packaging machine 1 of this Embodiment, the timing which the cutters 81 and 82 cut | disconnect the to-be-packaged sheet original fabric 152 is not specifically limited. For example, the cutters 81 and 82 may cut the packaged sheet original fabric 152 when the leading end of the packaged sheet original fabric 152 reaches the insertion start position E.

  Assuming that the material of the original sheet 152 to be packaged is paper and the material of the packaging material 102a is a polypropylene film, as shown in FIG. 5, the thickness of the original sheet 152 to be packed is Tf, and the packaging material 102a is When the thickness of the package 500 is Tp, the maximum thickness of the package 500 is T, and the distance between the upper guide member 661 and the lower guide member 671 is Δd, the following conditions (Equation 1) are satisfied. The packaging materials 102a and 102a preferably sandwich the original sheet 152 to be packaged.

  Furthermore, it is preferable that the cutters 81 and 82 cut the wrapping sheet original fabric 152 when the amount 152x of the sandwiched wrapping sheet original fabric 152 is 1 mm or more under the conditions shown in Equation 1. Here, when the amount of sandwiched sheet raw fabric 152 is less than 1 mm, the packaging sheet original fabric 152 is cut because the packaging sheet 102a is not sufficiently sandwiched by the packaging material 102a and 102a. At this time, the supply position of the original sheet 152 to be packaged is greatly deviated from the predetermined position, which is not preferable.

  As shown in FIG. 4, the sheet packaging machine 1 of the present embodiment has six original sheets to be packaged that have passed the cutting position C in the lower packaging material set 121 a that passes over the placement unit 6711. An anti-152 is placed and guided to the insertion start position E. Thereby, the sheet packaging machine 1 of this Embodiment can insert | pinch each to-be-wrapped sheet original fabric 152 between the packaging materials 102a and 102a easily. Further, since the mounting portion 6711 is configured from the constituent member (lower guide member 671) of the lower transport line 67 without providing another member, the number of parts can be reduced. Therefore, the sheet packaging machine 1 according to the present embodiment can further improve the supply performance of the packaged sheet 152a while suppressing the cost.

  Note that the guide means is not limited to the lower guide member 671 described in the present embodiment as long as it guides the six packaged raw sheets 152 to the insertion start position E. As another guide means, you may comprise from the some guide roller arrange | positioned instead of the lower side guide member 671, for example in reverse L shape.

  Further, in the sheet packaging machine 1 of the present embodiment, the six packaging material sheets 152 sandwiched between the packaging material sets 121a and 121a are placed in the lower packaging material set 121a until being cut. It is supported. Therefore, since the sheet packaging machine 1 according to the present embodiment prevents the supply position of the packaged sheet 152a from being shifted, the supply performance of the packaged sheet 152a can be further improved.

  Moreover, as shown in FIG.4 (b), the movement of each to-be-wrapped sheet original fabric 152 is controlled when the cutting | disconnection side part 1521 is clamped by the packaging materials 102a and 102a at the time of a cutting | disconnection. Further, the movement of the uncut side portion 1522 of the original sheet 152 to be packaged is restricted by hitting the regulating member 83 and the passage 7131 of the guide member 713 at the time of cutting. Thereby, both the cutters 81 and 82 can cut | disconnect the to-be-wrapped sheet original fabric 152 easily. Therefore, the sheet packaging machine 1 of this Embodiment can further improve the supply performance of the to-be-packaged sheet 152a.

  Furthermore, since the sheet packaging machine 1 of the present embodiment also uses the restricting means as the constituent member (guide member 713) of the packaged sheet original fabric conveying means 7, the number of parts can be reduced. Therefore, the sheet packaging machine 1 of the present embodiment can further improve the supply performance of the packaged sheet 152a while suppressing the manufacturing cost. In addition, since the guide member 713 includes a removable cover 715, the operator can easily set the packaged sheet original fabric 152 by removing the cover 715.

  Since the cover 715 is made of acrylic, the passage 7131 is visible from above. Thereby, the operator can easily confirm the state of the packaged sheet original fabric 152 passing through the passage 7131. Therefore, even if the packaged sheet original fabric 152 is caught in the passage 7131, the operator can immediately notice it and reset the packaged sheet original fabric 152. Therefore, in the sheet packaging machine 1 of this Embodiment, the usability accompanying conveyance of the to-be-packaged sheet original fabric 152 can be improved.

  The passage 7131 is formed with reference to the groove 7144 of the guide member main body 714. For this reason, when the passage 7131 is formed, the surface of the original member to be the guide member main body 714 may be processed. Therefore, in the guide member 713 of the present embodiment, since the fine processing work accompanying the formation of the passage 7131 is reduced, the manufacturing cost can be suppressed.

  If the passage 7131 is visible from the outside, by using a transparent cover such as a glass cover in addition to the acrylic cover 715 described in this embodiment as a cover for the guide member. The same effects as those described in this embodiment can be obtained. Further, in the case of the integrally formed guide member, since the passage can be visually observed from the outside if it is formed entirely from a transparent material, the same effect as the effect described in the present embodiment can be obtained. Moreover, as a cover material of other embodiment, you may form so that a part of groove | channel 7144 may be exposed, without forming a cover from a transparent material, for example.

  In addition, although the case where it comprised so that the to-be-packaged sheet original fabric 152 may be inserted | pinched in a horizontal state was demonstrated in this Embodiment, the insertion direction of the to-be-packaged sheet original fabric 152 is not specifically limited. For example, the configuration described in this embodiment may be applied even when the original sheet 152 to be packaged is inserted vertically. In the present embodiment, the six-row sheet wrapping machine 1 has been described. However, the present invention may be applied to other multi-row wrapping machines and single-row wrapping machines.

  As described above, in the sheet supply apparatus of the present invention and the sheet packaging machine using the same, since the supply performance of the sheet to be packaged can be improved, it is sufficiently used in the technical field of the sheet supply apparatus and the sheet packaging machine. can do.
