Description

  The present invention relates to an apparatus for carrying out a rectangular parallelepiped packaging container manufactured by a filling and packaging machine for juice or the like.

  As shown in FIG. 1, a rectangular parallelepiped container 1 filled with juice or the like produced by a filling and packaging machine has a vertical direction, that is, a top portion 2 and a bottom portion 3. This type of packaging container is first formed as a pillow-shaped container by a filling and packaging machine, and its end is bent while being conveyed by an intermittent drive conveyor in an inverted state, and then shaped into a rectangular parallelepiped container. As shown, the container 1 stopped at the container discharge position scrapes and discharges the upper part of the container by the push pin 5 provided in the continuous drive endless chain 4 in the container longitudinal direction (container transport direction of the intermittent drive transport conveyor), The container was upright and unloaded.

  However, in the conventional container unloading device, the containers filled with juice or the like must be sequentially discharged by the upper scraping mechanism 6 of the container using a small space in the container transport direction of the intermittent drive conveyor. When the container unloading device is applied to, for example, a high-speed filling and packaging machine having a production capacity of 7000 packs or more, particularly 8000 packs or more per hour, even if the discharge due to the upper scraping of the container becomes unstable, In the structure in which the container is brought upright by being moved obliquely upward in the direction of travel and then dropped while being inverted, the container is transferred at a high speed, so the container is often crushed or overturned due to the impact at the time of the inverted fall. there were.

  The subject of this invention is providing the container carrying-out apparatus which can carry out the container filled with the juice etc. which are manufactured especially by the high-speed filling packaging machine at high speed and reliably.

  The present inventors have provided a container carrying-out device capable of carrying out a container filled with juice or the like manufactured by a high-speed filling and packaging machine having a production capacity of 7000 packs or more, especially 8000 packs or more, at high speed and reliably. As a result of earnest research to develop, a rectangular parallelepiped container having an up-down direction is discharged in a direction perpendicular to the container transport direction instead of the container transport direction of the intermittently driven transport conveyor as in the conventional unloading device, and then the container is rotated.・ By erecting, it was confirmed that containers manufactured from high-speed filling and packaging machines of more than 7000 packs per hour, especially 8000 packs per hour, as well as conventional filling and packaging machines, can be carried out at high speed and reliably. The invention has been completed.

  That is, the present invention provides a discharging means including a container pushing member for discharging a rectangular parallelepiped container having an up-down direction in a direction perpendicular to the container transport direction, and pushes the discharged rectangular parallelepiped container with the container pushing member. However, the erecting guide member has an erecting means for erecting with the erecting guide member, the erecting guide member includes a guide for guiding the container bottom and a guide for guiding the vicinity of the top of the container, and the container pushing member has the center of gravity or rotation of the container The present invention relates to a container carry-out device including a mechanism that pushes an area including a center.

  Further, according to the present invention, the erecting guide member has a circular cross section, has a notch for allowing the container pushing member to pass in the longitudinal direction, and a transfer conveyor is disposed on the extension of the erecting guide member. Further, the present invention relates to a container carry-out device in which the transfer speed of the transfer conveyor is set faster than the moving speed of the container pushing member.

  Hereinafter, although the Example about the container carrying-out apparatus concerning this invention is described with reference to drawings, this invention is not limited to the Example described in these drawings.

  A rectangular parallelepiped packaging container filled with juice or the like and having a vertical direction is manufactured, for example, by a high-speed filling packaging machine as shown in FIG. That is, the roll-shaped packaging material web is sequentially rewound, sterilized and then formed into a tube shape, filled with juice and the like, then laterally sealed and cut, and formed into a pillow-like container 7.

  Next, while the pillow-like container 7 is transported by the intermittently driven container transport conveyor in an inverted state, its end is bent and shaped into a rectangular parallelepiped container 1.

  As shown in FIGS. 4 and 5, the intermittently driven container transport conveyor 10 spans a pair of front and rear sprockets 11A and 11B, a pair of endless chains 12 wound around these sprockets, and both chains. A large number of holders 13 are provided.

  The holder 13 of the intermittently driven container transport conveyor 10 is a T-shape composed of a side plate 14 and a bottom plate 15. When the holder 13 moves on the upper side of the chain 12, the side plates 14 of the two holders 13 adjacent to each other in front and rear are parallel. And the bottom plate 15 is connected in a straight line, the rectangular parallelepiped container 1 is sandwiched between the side plates 14 of the holder 13 from the traveling direction, and the rectangular parallelepiped container 1 is received across the bottom plate 15 of the holder 13. The rectangular parallelepiped container 1 is held by a holder 13.

  When the holder 13 stops at the container discharge position (see FIG. 5) in the middle of turning around the sprocket 11A, the inclination angle of the side plates 14 of the front and rear holders 13 is opened so that the front end side is widened. The container 1 is easily taken out from between. Further, at this time, the container 1 is held in a stable state in which the container 1 is tilted upward in the traveling direction, and can be discharged more stably than when it is inverted with the container top as the bottom surface.

  A discharge unit 20 having container pushing means is disposed at the end of the intermittently driven container transport conveyor 10. The discharge unit 20 includes a pair of sprockets 21A and 21B, an endless chain 22 wound around the sprockets 21A and 21B, and a large number of L-shaped plates 23 attached to the chain 22 at equal intervals. Yes.

  The endless chain 22 is wound around a sprocket 21A that is driven in a direction orthogonal to the intermittently driven container transport conveyor 10 and a sprocket 21B that is driven by the sprocket 21A.

  As shown in FIG. 6, the L-shaped plate 23 is attached to the endless chain 22 through an elastic member 24 such as rubber at equal intervals, and the holder 13 of the intermittently driven container transport conveyor 10 is attached to the sprocket 11A. The intermittent drive container transport conveyor moves so as to intersect the container discharge position that is stopped while being swung around, and the L-shaped plate 23 passes while the intermittent drive container transport conveyor 10 is stopped. 10 and the endless chain 22 are adjusted to be synchronized.

  A cylindrical guide 32 having a notch 31 extending along the chain 22 of the discharge unit 20 on the side perpendicular to the container transfer direction of the intermittent drive container transfer conveyor 10 at the container discharge position, and a guide An upright guide unit 30 having an attached guide bar 33 is arranged.

  The cylindrical guide 32 is provided in parallel along the endless chain 22 and has a cutout 31 in the longitudinal direction through which the L-shaped plate 23 passes. Since the L-shaped plate 23 is attached to the endless chain 22 so as to always push the region including the center of gravity or the center of rotation of the rectangular parallelepiped container moving within the cylindrical guide 32, the L-shaped plate 23 is continuous. When the rectangular parallelepiped container is moved, the one end of the rectangular parallelepiped container abuts on the guide rod 33 and is guided, and is smoothly conveyed while turning into an upright state.

  A transfer conveyor 40 is arranged on the extension of the cylindrical guide 32. The transfer conveyor 40 transfers the rectangular parallelepiped container 1 erected by the erecting guide unit 30 to another processing apparatus (not shown). The transfer speed on the transfer conveyor 40 is based on the moving speed of the L-shaped plate 23. Since it is set quickly, when the L-shaped plate 23 changes its direction from the forward path to the return path by the sprocket portion 21B, the L-shaped plate 23 does not push the rectangular parallelepiped container and cause it to fall.

  Since the container carry-out device according to the present invention is configured as described above, when the holder 13 stops at the container discharge position, the L-shaped plate 23 attached to the chain 22 that is continuously driven, The rectangular parallelepiped container 1 which is in a state of being stable in the traveling direction diagonally upward is discharged in a direction perpendicular to the carrying-out direction of the intermittently driven container transport conveyor 10, and the discharged rectangular parallelepiped container 1 is placed at the top of the container. The rectangular parallelepiped container 1 is connected to the guide bar 33 by a part of the guide rod 33 in the cylindrical guide 32 and a part of the container bottom part in contact with the cylindrical guide 32, and the L-shaped plate 23 continues to push. The upright rectangular parallelepiped container is transferred to the transfer conveyor 40 while being pushed by the L-shaped plate 23, while sliding at the abutted portion of the cylindrical guide 32. 0 on at raising the conveying speed, away from the L-shaped plate 12. Thereafter, the L-shaped plate 23 returns to a position where it intersects the intermittently driven container transport conveyor 10 on the return path, and repeats the pushing operation.

  Although preferred embodiments of the present invention have been described above, the following embodiments are also encompassed by the present invention.

  In the above embodiment, the rectangular parallelepiped container 1 discharged from the container discharge position is erect by the erecting guide unit 30 and then transferred by the transfer conveyor 40. In addition, a transfer means such as a shooter can be appropriately provided in place of the transfer conveyor 40, and there is a case where the rectangular parallelepiped container does not necessarily have to be erected. In such a case, the rectangular parallelepiped discharged from the container discharge position After the container 1 is appropriately rotated, it can be smoothly transferred to the next transfer means.

  In the above embodiment, the cylindrical guide 32 and the guide rod 33 are used as the guide member of the container such as the upright guide unit 30, but the guide member of the container can be any one that can rotate and erect the container. Any shape such as a rail-shaped guide for guiding the container bottom and a guide bar may be used.

  In addition, the cylindrical guide 32 used in the above embodiment is not limited to a cylindrical shape but may have various shapes such as a U-shape or a right angle as long as the cylindrical guide 32 has a circular cross section as in the cylindrical shape. The transport direction can be set freely. Similarly, the shape from the start point to the end point of the guide rod 33 that guides the vicinity of the top of the container and rotates and erects may be a straight line portion that is bent or a spiral shape.

  In the above embodiment, the discharge from the intermittently driven container transport conveyor 10 and the pushing of the rectangular parallelepiped container 1 in the cylindrical guide 32 are combined by the L-shaped plate 23, but each is carried out by a separate pushing member. In addition, the L-shaped plate 23 does not have to be L-shaped as long as it can reliably push the rectangular parallelepiped container, and the L-shaped plate 23 may be changed to other shapes such as a round bar instead of a plate. You can also.

  Furthermore, in the said Example, discharge | emission of the container was performed in the container discharge position in the middle where the holder 13 is swung around the sprocket 11A, but the rectangular parallelepiped container 1 is in an inverted state on the intermittent drive container transfer conveyor 10. It may be carried out at the container discharge position. In that case, the rectangular parallelepiped container 1 can be discharged to a turret adjacent to the intermittently driven container transport conveyor 10, inverted and upright by the turret, and then transferred. .

  According to the present invention, a container filled with juice or the like produced by a high-speed filling and packaging machine having a production capacity of 7000 packs or more, particularly 8000 packs or more per hour, as well as conventional filling and packaging machines, It can be carried out quickly and reliably without falling.

  In addition, since the container discharge position on the intermittently driven conveyor is in a stable state where the container is tilted upward in the traveling direction, not only can it be discharged stably, but it will be required for subsequent reversion to an upright state. The rotation angle is small, the guide rod may be short, and the container conveyed at high speed can be reliably carried out.

  Furthermore, since the L-shaped plate 23 that pushes the container is attached to the endless chain 22 at equal intervals via an elastic member 24 such as rubber, even if the container is unexpectedly clogged during transportation for some reason. The elastic member 24 is bent at the portion, and the apparatus is not seriously damaged.
