Description

  The present invention relates to a method for manufacturing a boxed tissue paper product in which a plurality of tissue cartons of tissue paper that can be taken out one by one from a box outlet are packaged as one pack.

  Conventionally, in manufacturing a boxed tissue paper product, a tissue paper bundle is boxed in a tissue carton, and then the tissue carton is transported to a packaging process, and a plurality of tissue cartons are packaged as one pack.

  FIG. 8 is a view showing the appearance of a conventional tissue carton. In a typical box-shaped tissue carton 1, the height h, the depth d, and the width w are in a relationship of h <d <w. When transporting such a tissue carton in the manufacturing process, it is transported in a posture with the surface composed of width w and height h down rather than transported in a posture with the surface composed of width w and depth d down. This improves the conveyance efficiency. However, as described above, since the relationship between the height h and the depth d is such that the height h <the depth d, the conveyance is performed with the surface composed of the width w and the height h facing down. In this case, the transport efficiency is improved, but the tissue carton 1 is likely to fall over, which causes the transport of the tissue carton 1.

  In view of these points, in Patent Document 1, in order to improve the conveyance efficiency, the tissue paper bundle 1 is boxed in a posture in which the surface composed of the width w and the depth d is faced down, and then the tissue carton 1 is erected ( A posture in which the surface composed of the width w and the height h is faced down), and the posture is maintained by the carton regulating member, and the cartons are prevented from falling down, thereby improving the conveyance efficiency of the tissue cartons 1 Is disclosed.

For example, when 400 tissues are stored in the tissue carton 11, 400 stands of the tissue winding drum 24 are arranged in an aligned state.

  The tissue bundle cutting unit 16 is an area in which the tissue bundle 25 c folded in a stacked state by the tissue folding unit 15 is cut at regular intervals by the cutter device 26 to obtain the tissue bundle 25. The tissue bundle insertion part 17 is an area for inserting the tissue bundle 25 cut by the tissue bundle cutting part 16 into the tissue carton 11. The tissue bundle insertion portion 17 includes a tissue bundle conveyance line that conveys the cut tissue bundle 25 at regular intervals, and a tissue carton conveyance that conveys empty tissue cartons 11 at regular intervals in synchronization with the tissue bundle conveyance line. Lines are arranged in parallel. The tissue carton transport line transports the tissue carton 11 along the depth d direction perpendicular to the width w thereof. The tissue cartons 11 are colored, and the five different cartons 11 are packed as one pack. Therefore, the tissue cartons 11 sent to the tissue carton transport line one by one have already been color-coded, and the five-color tissue cartons 11 are transported in order. The tissue carton 11 at this time is in a collapsed state collapsed in advance. From this state, a surface 27 defined by the height h and width w of the tissue carton 11 (hereinafter referred to as front and rear surfaces) 27 is erected vertically to form a space 28 in which the tissue bundle 25 is accommodated. To do. In this case, on the both sides in the width direction of the upper and lower surfaces 12 and the front and rear surfaces 27 of the tissue carton 11, surfaces defined by the height h and the depth d of the tissue cartons 11 (hereinafter referred to as left and right surfaces) 29 The four cover plates 30 and 31 for sealing are opened (see FIG. 3). The tissue bundle 25 is pushed into the space 28 of the tissue carton 11 by the push rod 32 from the side facing the tissue bundle conveyance line of the left and right surfaces 29 of the tissue carton 11.

  The tissue carton sealing portion 18 is a region that seals the left and right lid plates 30 and 31 of the tissue carton 11 in which the tissue bundle 25 is accommodated using an adhesive. First, a pair of cover plates 30 following the front and rear surfaces 27 of the tissue carton 11 are bent, and then an adhesive is applied to one cover plate 31 following the upper and lower surfaces 12 of the tissue carton 11. Then, the lid plate 31 following the upper and lower surfaces 12 is bent and the four lid plates 30 and 31 are joined to each other on the left and right sides, thereby sealing the left and right surfaces 29 of the tissue carton 11. The defective carton detection unit 19 is an area in which the tissue carton 11 whose left and right surfaces 29 are not properly sealed by the tissue carton sealing unit 18 is detected as a defective product.

  FIG. 4 is an enlarged view of the distribution unit 20 in FIG. The distribution unit 20 in the present embodiment includes a well-known automatic line distribution device (channelizer) 35 and includes three transfer channels 36 to 38 that can be switched continuously. The first and second transport channels 36 and 37 are connected to the subsequent posture changing unit 21. The remaining transport channels 38 are connected to a discharge conveyor 39 disposed between the pair of posture changing units 21. The discharge conveyor 39 discharges the tissue cartons 11 determined to be defective by the defective carton detection unit 19 and, if necessary, the same packed cartons 11 as the tissue cartons 11 to the outside of the transport line. belongs to.

  FIG. 5 is an enlarged view of the posture changing unit 21 in FIG. The posture changing unit 21 according to the present embodiment includes a pair of upper conveyors 40 connected to the first and second transport channels 36 and 37 of the sorting unit 20 and a pair connected to the pair of upper conveyors 40 via a chute 41. Lower conveyor 42. That is, the chutes 41 having a ¼ arc shape are disposed between the downstream end of the upper conveyor 40 in the transport direction and the upstream end of the lower conveyor 42 in the transport direction. When the tissue carton 11 is moved from the upper conveyor 40 to the lower conveyor 42, the guide member 43 that guides the movement of the tissue carton is along the guide surface of the chute 41 so that the front and rear surfaces 27 of the tissue carton 11 are directed in the vertical direction. It is arranged almost parallel to this.

  FIG. 6 is a diagram illustrating a conveyor used after the posture changing unit 21 in the present embodiment.

  Thus, the tissue carton 11 whose posture during transportation is changed is an unstable posture because the front and rear surfaces, which are surfaces defined by the height h and the width w of the tissue carton 11, are vertically oriented. Yes Tish Carton 11 is easy to fall.

  Therefore, in the present embodiment, the posture changing unit 21 and the following convey the tissue carton 11 using a conveyor having a configuration as shown in FIG. The conveyor 400 used after the posture changing unit 21 is composed of a high-speed conveyor 100, a medium-speed conveyor 200, and a low-speed conveyor 300. The tissue cartons 11 that have been conveyed are transferred from the high-speed conveyor 100 in the arrow α direction to the low-speed conveyor. It is conveyed in the direction of 300. Here, the conveying speed of the high-speed conveyor 100 is the same as the speed of the lower conveyor 42 in the posture changing unit 21. The speed of the medium speed conveyor 200 is slower than that of the high speed conveyor 100, and the speed of the low speed conveyor 300 is slower than the speed of the medium speed conveyor 200. In addition, the speed of each conveyor is set so that the discharge amount of the tissue cartons 11 per unit time of the high-speed conveyor 100, the medium-speed conveyor 200, and the low-speed conveyor 300 is the same. By transporting the tissue cartons 11 with each conveyor having such a configuration, the distance between the transported tissue cartons becomes narrower as each conveyor passes, and the tissue cartons are transported in close contact with each other on the low speed conveyor 300. Is done. Even in a posture in which the front and rear surfaces of the tissue carton 11 are up and down, by transporting the tissue cartons in close contact with each other, the tissue cartons 11 can be transported in a stable state, and the tissue cartons 11 can be prevented from falling down. In the present embodiment, the speed of the conveyor is decelerated in three stages of high speed, medium speed, and low speed, but the present invention is not limited to this, and any structure that decelerates in multiple stages may be used. .

  FIGS. 7A and 7B are views showing a process of dividing the tissue carton 11 into five pieces performed immediately before the pack packaging unit 22. 7A is a top view, and FIG. 7B is a cross-sectional view taken along VIIb-VIIb in FIG. 7A. Since five tissue cartons 11 are packed as one pack, the five-color tissue cartons 11 packed as one pack are conveyed in the direction of arrow α in a state of being in close contact with each other. The low speed conveyor 300 is a conveyor connected to the low speed conveyor 300 of the posture changing unit 21 and is the same as the low speed conveyor 300 of FIG. A pressing stopper 71 is provided at a position where five tissue cartons 11 are separated from the terminal portion of the low-speed conveyor 300 so that the tissue cartons 11 conveyed by the cylinder 72 can be pressed and released. . When the tissue carton 11 is pressed by the pressing stopper 71, the tissue carton 11 is sandwiched between the guide 70 and the pressing stopper, and the conveyance is stopped. The five tissue cartons 11 that have passed through the pressing stopper 71 stop at the end of the low speed conveyor 300 and are transferred to the conveyor 500. A paddle 73 that is rotated by a chain as shown in FIG. 7B is provided at the end of the low speed conveyor 300, and the transported tissue cartons 11 are moved in parallel from the low speed conveyor 300 to the conveyor 500. Can be moved. During the movement by the paddle 73, the pressing stopper 71 holds the tissue carton 11. When the movement by the paddle 73 is completed, the pressing by the pressing stopper 71 is released and the tissue carton on the low speed conveyor 300 is conveyed again. By repeating such an operation, five tissue cartons packed as one pack are transported together on the conveyor 500.

  In the present embodiment, the transport of the tissue carton is stopped by the pressing stopper 71. However, the present invention is not limited to this. For example, a structure in which a fixed stopper is provided at the end of the low speed conveyor 300 to stop the transport may be used. .

  The pack packaging unit 22 in this embodiment includes two packaging machines (not shown) so as to follow the speed of the conveyance line from the tissue folding unit 15 to the defective carton detection unit 19. These two packaging machines are arranged adjacent to the downstream side in the transport direction of the pair of lower conveyors 42 of the posture changing unit 21. Each packaging machine takes out five tissue cartons 11 in order from the top side in contact with the stopper from the group of tissue cartons staying on the downstream side in the conveyance direction of the lower conveyor 42 of the posture changing unit 21, and removes them. It is packed with a transparent resin film 13. Furthermore, both ends of the carrying handle 14 formed of a resin film are joined to the transparent resin film 13 for packing by heat sealing. The packed tissue cartons 10 packed in the pack packing unit 22 in this way are stored in predetermined card packs in a cardboard box (not shown) and are transported toward each consumption area.

  In this way, the tissue cartons are transported while being narrowed between adjacent tissue cartons as they are transported downstream in the transport, and the transported tissue cartons are translated by the paddles so that a predetermined number of tissue cartons are Divide into groups. As a result, the transport efficiency of tissue cartons can be improved with a simple and low-cost configuration, and finally a manufacturing method for boxed tissue paper products packed as a pack of 5 can be realized. It was.
