  Since such a conventional packing apparatus 110 uses the craft packaging bag 101, the craft packaging bag 101 is expensive, and the transportation cost by the package 105 is increased. In addition, since the size of the craft packaging bag 101 is determined, an extra space may be generated in the bag depending on the size and shape of an object to be packed such as the packed product 102. That is, it is difficult for the packing device 110 that only pushes into the opening to insert and pack the stacked-pack products 103 into the craft packaging bag 101 without gaps.

  Therefore, the size of the package 105 is larger than the size of the packaged item, and the loading amount is smaller than the size of the packaged product to be originally transported, thereby reducing the transport efficiency. Furthermore, the conventional packing apparatus has a long installation area because the X direction shown in FIG. It was necessary.

  Then, this invention aims at providing the packing apparatus and packing method which pack a to-be-packaged object with the wrapping paper drawn | fed out from the base paper roll in order to solve this subject.

A wrapping mechanism that pushes in the wrapping paper, and the wrapping base paper in a state in which the article to be packed is wound in the holding portion is separated from the base paper roll and separated. It the upper and lower end portions of the wrapping paper, and has a folding fold mechanism includes a pair of folding plates respectively bent at a right angle vertically with, a tape applying mechanism for pasting the tape at a predetermined position of the wrapping paper tucked, the The wrapping mechanism is provided with a pair of upper and lower guide rollers according to the pushing height of the article to be packed. The pair of upper and lower guide rollers causes the wrapping base paper to be horizontally directed toward the holding portion. The wrapping base paper is separated between the pair of upper and lower guide rollers and the holding portion while being fed and tightly wound along the shape of the packed object. It is characterized by this.

Further, in the packing apparatus of the present invention, the wrapping mechanism includes a filling pusher that presses the packaged object against the packaging base paper in the packaging preparation state, and a packaging plate that is arranged vertically on the opposite side. Preferably there is.
Further, in the packing device of the present invention, the paper feed mechanism is provided with two base paper rolls at the top and bottom, the base paper for packaging fed out from each base paper roller is overlapped by a stacking roller, and the two base papers for packaging are stacked. It is preferable that it hangs down and constitutes the packaging preparation state.

The packaging method of the present invention creates a package by wrapping an article to be packaged with a wrapping paper obtained by cutting a wrapping base paper fed from a base paper roll, and then sticking a tape to a predetermined portion of the wrapping paper folded. A paper feeding step in which a packaging base paper from the base paper roll is fed out through a roller and the packaging base paper on the leading end side in the feeding direction is hung down to prepare a packaging preparation; and the packaging base paper by the roller In such a state that the object to be packed is pressed against the packaging base paper in the packaging preparation state by an extruding means and the packaging object is pushed in while holding the base paper for packaging in the holding portion arranged on the opposite side.

  According to the present invention, the article to be packed is pressed against the packaging base paper that is drawn out of the base paper roll and hangs down, so that it can be wound tightly by receiving an appropriate resistance due to its own weight. it can. For this reason, the package formed by attaching the tape can be almost the size of an object to be packed, and the transportation efficiency can be improved by performing loading on a truck or the like without waste. In addition, since the packaged material is wrapped around the wrapping base paper that is ready for wrapping, the packaging craft paper can be spread sideways and wrapped, and the space for the wrapping process can be greatly reduced. It can be downsized.

It is the figure which showed the packaging method in the packaging apparatus of embodiment, and has shown one part from the apparatus side surface direction. It is the top view which showed the packing apparatus of embodiment notionally. It is the perspective view which showed the conventional packaging method using a craft packaging bag. It is the top view which showed the conventional packing apparatus notionally.

  Next, a packing apparatus and a packing method according to the present invention will be described below with reference to the drawings. The packaging device of the present embodiment is to package a plurality of items to be packed such as packed products using kraft paper as in the past, but instead of using a shaped craft packaging bag, The article to be packed is directly packaged by the craft base paper fed from the base paper roll. FIG.1 and FIG.2 is the figure which showed the packaging method in such a packaging apparatus of this embodiment, and has shown from the apparatus side surface direction.

  First, in the packaging device 10 of the present embodiment, two base paper rolls 1 and 2 are mounted vertically on the upstream side of the device. The base paper rolls 1 and 2 are supported by a rotating shaft, and the base paper rolls 1 and 2 are fed with craft base papers 31 and 32 wound around each other. The craft base papers 31 and 32 are sent to the laminating roller 5 through the reverse roller 3 and the tension roller 4 while changing the direction up and down. The two craft base papers 31 and 32 are overlapped by the laminating roller 5 to form a two-layer wrapping paper. Here, the craft base papers 31 and 32 stacked in two sheets are collectively referred to as a multi-layer craft base paper 30.

  The multilayer kraft base paper 30 is sent sideways, and the tip side portion is lowered downward from a high position via a pair of laminating rollers 6. The multilayer kraft base paper 30 hangs down straight due to its own weight without being restrained, and this state is a packaging preparation state for packaging the article 80 to be packed. On the other hand, the objects to be packed 80 are transported into the packing device 10 by the supply conveyor 7, and a plurality of objects to be packed 80 are overlapped and combined into one. This is provided with a stacking mechanism (not shown), and the article 80 to be packed on the table 8 is arranged close to the multilayer kraft base paper 30 that hangs down.

  In the present embodiment, a method of directly packaging an object to be packed 80 on the multilayer kraft paper 30 is employed. Therefore, a filling pusher (comprised of an air cylinder and a servo motor) 9 is arranged for the stacked articles 80, and the article 80 to be pushed out by the filling pusher 9 is placed on the multilayer kraft paper 30. It is supposed to get involved. In addition, a pair of guide rollers 11 are arranged on the opposite side across the multilayer kraft base paper 30 at a predetermined interval in accordance with the pushing height of the article 80 to be packed. Further, on the opposite side, a holding portion is configured in which the packaging plates 12 are arranged in two rows. This holding part is configured to allow the multilayer kraft base paper 30 to be rolled in while supporting the pushed object 80 to be sandwiched between the upper and lower sides.

  The packaging plate 12 has plates arranged in parallel in the vertical direction, and is arranged in accordance with the vertical dimension of the article 80 to be extruded. Thereby, the lower side of the multilayer kraft base paper 30 suspended above is rolled up according to the movement of the article 80 to be pushed. Next to the upper guide roller 11, a cutter 13 for cutting the multilayer kraft base paper 30 folded in the orthogonal direction is installed. Hereinafter, the multilayer kraft base paper 30 that is cut by the cutter 13 and wraps the article 80 to be packed is referred to as a craft paper for packaging 30x. As shown in FIG. 2, the packaging kraft paper 30 x has a horizontally inverted shape like a reverse U shape in the support portion, and its upper and lower ends are aligned at substantially the same position.

  Further, adjacent to the upper and lower packaging plates 12, a folding plate 15 for folding the upper and lower ends of the packaging kraft paper 30x is provided. The upper and lower ends of the packaging kraft paper 30x are bent by 90 degrees by the folding plate 15, and the article to be packed 80 is wound. And the tape sticking mechanism which sticks a tape with respect to the overlapped edge part is provided. In such a wrapping process O, the kraft kraft paper 30x in which the article 80 is wrapped and wrapped is conveyed not shown so as to be sent to the flap folding process P, the tape applying process Q, and the reverse conveying process R shown in FIG. Means are provided. Each process is provided with a folding mechanism, a pasting mechanism, and a reversing mechanism (not shown).

  Next, FIG. 3 is a plan view conceptually showing the packaging device 10 of the present embodiment as described above, similarly to the conventional example shown in FIG. A base paper roll 1 (and a base paper roll 2 (not shown)) is attached to the apparatus end on the right side of the drawing. As for the base paper rolls 1 and 2, the rotation shaft supported by the bearing is connected to the motor via the gear, and the rotation is transmitted at a predetermined timing. From the base paper rolls 1 and 2, a craft base paper 31 (and a craft base paper 32 not shown) having a predetermined width is fed out, and in a direction (the Y direction) orthogonal to the feeding direction (the X direction shown in FIG. 3). A supply conveyor 7 is provided.

  The reverse roller 3, the tension roller 4, the laminating roller 5, and the laminating roller 6 are arranged facing the Y direction, which is the conveying direction of the supply conveyor 7, and an object 80 to be packed sent from the supply conveyor 7 is also in the Y direction. Is sent so that the dimension becomes longer. On the other hand, the wrapping process O, the flap folding process P, the tape applying process Q, and the reverse conveying process R are provided in a line along the feeding direction (X direction) from the base paper rolls 1 and 2.

  In the wrapping step O, a tape reel 16 is arranged, a drawing means for extending the tape therefrom, a cutting means for cutting the tape at a predetermined length, and a predetermined length at the front side end of the stacked kraft paper 30x. A tape applying mechanism is provided that includes pressing means for pressing the tape 16a that has been cut. In the next flap folding process P, a folding mechanism is provided. The folding mechanism is for folding open portions on both sides in the longitudinal direction (Y direction) of the packaging kraft paper 30x in which the article 80 is wrapped in the wrapping process O.

  The folding mechanism includes a vertical folding means having a plate for bending and pressing the open portion 90 degrees from the top and bottom, and a left and right folding means having a plate for pressing the flap portion formed on the left and right thereby. In the subsequent tape application process Q, a tape application mechanism is provided. In the tape applying mechanism, the tape reels 17 and 18 are arranged on both the left and right sides (Y direction both sides), the drawing means for extending the tape therefrom, the cutting means for cutting the tape by a predetermined length, and the overlapped flap portions And pressing means for pressing the tapes 17a and 18a cut to a predetermined length. And in the reverse conveyance process R, the reverse mechanism which scoops up the to-be-packaged item 80 from the bottom, and rotates 90 degree | times to the advancing direction (X direction) is provided.

  Next, in the above packing apparatus 10, packing is performed as follows. First, the craft base papers 31 and 32 are fed out from the base paper rolls 1 and 2, respectively, and the multilayer craft base paper 30 stacked in the middle hangs down before the wrapping step O. The packed object 80 is pressed against the multilayer kraft base paper 30 by the filling pusher 9. At this time, the multi-layer kraft base paper 30 is pulled up at the leading end side and pushed into the packaging plate 12 arranged up and down while the article 80 to be packed is rolled up. At that time, the multilayer kraft base paper 30 is tightly wound along the shape of the article 80 to be packed.

  Thereafter, the packaging kraft paper 30x is cut from the multilayer kraft base paper 30 by the cutter 13, and a tape 16a cut to a predetermined length from the tape reel 16 is attached to the upper and lower ends of the stacked kraft paper 30x. The wrapping kraft paper 30x is formed into a cylindrical shape by such body winding packaging, and is sent to the next flap folding process P. In the flap folding process P, the opening portions at both ends in the longitudinal direction of the packaging kraft paper 30x are folded, and the resulting flap portions 30z are overlapped.

  The package 90 that encloses the article 80 to be packed is sent to the tape applying process Q, and the tapes 17a and 18a cut to a predetermined length from the tape reels 17 and 18 are attached to the overlapped flap portion 30z. It is done. Then, in the subsequent reverse conveyance process R, the sealed package 90 is rolled 90 degrees and placed on the discharge conveyor 19 with the surface to which the tape 16a is attached facing up and down in the Y direction shown in FIG. Sent to.

  As described above, according to the packaging device 10 of the present embodiment, the packaged object 80 is pressed against the multilayer kraft base paper 30 that is drawn out from the base paper rolls 1 and 2 and hangs down. It can be wound tightly with moderate resistance. Therefore, the package 90 that has been sealed is wrapped with the craft paper 30x for packaging along the shape of the packaged object 80, and can be approximately the size of the packaged object 80. Therefore, unlike the conventional case of using a kraft packaging bag, an extra gap is not generated between the kraft paper 30x for packaging and the article 80 to be packed. Transport efficiency can be improved.

  Even with the same overlapping packaging, Patent Document 2 discloses a method in which a kraft paper for packaging is cut in advance to a predetermined size from a base paper roll and then wrapped to be packed. However, in this case, the process of cutting the packaging kraft paper and the process of wrapping the packaging kraft paper and the article to be packed are separated, and the apparatus is complicated as well as enlarged. In this respect, in the packaging apparatus 10 of the present embodiment, both the wrapping and cutting steps are performed at one place, and the kraft paper for packaging is spread laterally in order to wrap the hanging kraft paper in the suspended state. However, the space for the wrapping process can be greatly reduced.

Moreover, in this embodiment, when moving the to-be-packaged object 80 in the apparatus, the moving distance of the to-be-packaged object 80 that moves between the respective processes with the longitudinal direction being transverse is shortened. For this reason, the interval between the steps is shortened, and the entire apparatus can be made compact.
Furthermore, in the packing method described in Patent Document 2, it is difficult to tightly wrap the object to be packed, as in the case of using the craft packing bag. A gap will be created between the two and waste will occur when loading the truck. In this respect, the present embodiment is advantageous in that the object to be packed 80 can be tightly packaged with the packaging kraft paper 30x as described above.

  As mentioned above, although embodiment of the packing apparatus and the packing method which concern on this invention was described, this invention is not necessarily limited to this, A various change is possible in the range which does not deviate from the meaning.
