Description

  The present invention relates to a bag supporting element of a bagging and packaging machine, such as a self-supporting bag for packaging an article to be packaged, which has a thickness difference between its opening edge and bottom edge (hereinafter referred to as a wrapping bag). The present invention relates to an apparatus for supplying to a device.

  Flat bags formed by cutting a plastic tube into a predetermined length and closing one opening edge of the plastic bag are stacked with the opening edge aligned with the ruler wall of the storage box. Although a certain distance from the wall can always be sucked with a vacuum cup and supplied to the packaging machine, for example, a self-supporting wrapping bag or a wrapping bag with a zipper at the bag mouth does not have a lateral shift when stacked with uneven thickness. Since this occurs, there is a problem that each package cannot be supplied under the same conditions.

Therefore, in the following first patent document, the bag transported by the conveyor is slid down along the sliding plate surface waiting in an inclined state after being sequentially fed by the first vacuum cup and the second vacuum cup. After receiving the wrapping bag with a stopper protruding from the surface, erect the wrapping bag together with the above-mentioned sliding plate, and lift the sliding plate with a lift to insert the wrapping bag between the holding claws. Thus, a technique for supplying a sachet to a support element of a rotary packaging machine is disclosed.
Japanese Patent Application No. 2004-335215

  In short, the first patent document has a structure in which the wrapping bag is put on an inclined sliding plate by a parabolic swing motion of the second vacuum cup, but the second vacuum cup is a wrapping bag. Since the parts other than the bag mouth are hung from the second vacuum cup due to its weight, the majority of the bag is entangled with the end of the sliding plate and obstructs the complete bag supply. In addition, there is a problem in that the lateral displacement of the wrapping bag occurs due to an installation error of the apparatus.

  In order to solve the above-mentioned problem, the present invention fixes a first cylinder in a recumbent manner to the upper end of a first spindle arranged vertically, and extends the piston rod to a base frame at the tip of the piston rod of the first cylinder. A suction block for picking up the wrapping bag vertically stacked in the direction is arranged, and the wrapping bag picked up by the suction block is transported with a rotation driving device for transporting the set spindle along a circular path by a rotation of the first spindle. A bag take-out means comprising an extruding cylinder for pulling the bag away from the suction block, and a second Linder fixed to the upper end of the second main shaft adjacent to the first main shaft in a horizontal shape, The substrate is supported vertically at the tip of the piston rod, and the support plate is engaged with the vertical guide and screw rod arranged on the substrate to push it out of the suction block. The support bag receives the packing bag that is pushed out by the substrate and slides down along the substrate, and the second main shaft rotates the second spindle to carry the packing bag along the circular path by a set angle. It is constituted by a wrapping bag delivery means for making the wrapping bag insert into a support element of the wrapping machine by raising the main shaft.

  In the present invention, the first cylinder is fixed to the upper end of the first main shaft that is vertically arranged, and the packing that is vertically stacked in the extending direction of the piston rod is taken out from the base frame at the tip of the piston rod of the first cylinder. A block is arranged, and the rotational drive device that conveys the wrapped bag taken out by the suction block by a set angle along the circular orbit by rotation of the first main spindle, and the transported wrapped bag are separated from the suction block. An extruding cylinder and a bag take-out means comprising: a second Linder fixed to the upper end of the second main shaft, a substrate supported on the tip of the piston rod of the second cylinder, and adsorbed on the substrate by the extruding cylinder A support plate for receiving a wrapping bag pushed out from the block and sliding down along the substrate; A wrapper transfer means passing plug the tare to wrapper support elements of the packaging machine and constitutes a.

Furthermore, the present invention provides a rotary packaging device and a packaging supply device that constitute a packaging machine, wherein a straight line connecting the center of the packaging device and the center of the packaging support element located at the bag removal position from the center of the rotary packaging device and the longitudinal direction of the packaging supply device. It is arranged so that the center line of the direction intersects at right angles, and the packaging bag take-out means rotates 90 degrees in the central direction of the rotary packaging device and delivers the packaging bag to the packaging bag delivery means, and the packaging bag delivery means moves the packaging bag upward It is set as the structure which pushes up to a parcel bag support element.

  With the suction block at the tip of the piston rod of the first cylinder lying on the upper end of the first main shaft arranged vertically, the vertically wrapped bag is taken out, and the rotation of the first main shaft causes the packing bag to be circular orbited. Then, the bag is pushed away from the suction block by the pushing cylinder and pushed toward the facing substrate. In this case, the wrapping bag is always transported along the horizontal plane while being suspended from the suction block, and can be delivered without being entangled with the substrate.

  On the other hand, the substrate vertically supported by the piston rod of the second Linder at the upper end of the second main shaft is pushed out of the suction block by a support plate engaged with the longitudinal guide and screw rod arranged on the substrate, and Receiving the slipping bag, the second spindle is lifted and the bag is inserted into the support element of the packaging machine. In this case, the packing bag is fed into the support element of the packaging machine without leaving the substrate. There is an effect that the bag can be supplied to the support element without being beaten.

  Further, the rotary packaging device and the packaging supply device constituting the packaging machine include a straight line connecting the center of the packaging support element located at the bag removal position from the center of the rotary packaging device, and the longitudinal center line of the packaging supply device. By arranging at a position where and intersect at a right angle, the installation area of the packaging machine can be reduced.
