An opening method for an outer package of containers, comprising the steps of:
first, cutting film
1. Referring to fig. 3, the first cutting method is: three side wall surfaces of the packaging film 120 are automatically and continuously cut along the circumferential direction of the bottle packaging material 100 by a cutting knife 211, the three side wall surfaces respectively correspond to two shorter longitudinal edges and a longer transverse edge of the bottle packaging material, after cutting, the top film and the bottom film of the packaging film are only kept connected at the other transverse edge, and the connected transverse edge is used as a connecting edge 130.
2. Referring to fig. 4, the second cutting method is: first, the package material is moved relative to the two longitudinal fixed cutting blades 221, and the longitudinal fixed cutting blades 221 cut the two opposing longitudinal sides of the package material at the same time. Then, the blocking cylinder is opened or the bottle pushing cylinder is closed to stop the bottle packaging material from moving, and then the driving cylinder drives the transverse moving cutter 222 to move and cut along one transverse edge of the bottle packaging material, namely, the three edges of the packaging film are cut off in the same way.
Wherein, no matter the first cutting path or the second cutting path is adopted, the cutting position of the film cutting device for cutting the packaging film is preferably as follows: 1. in the height direction of the bottle packing material, the cutting position is located at the height position where the outer diameter size of the container bottle is the smallest, the container bottle such as a medicine bottle generally has a bottleneck, the cutting position of the packaging film of the container bottle is generally consistent with the height position of the bottleneck, the distance between the packaging film and the bottle body of the container bottle is the largest, the packaging film is in a tight state, the cutter can easily cut the packaging film without touching the bottle body, and particularly for the container bottle made of plastic materials, the risk of scratching can be avoided; and, because the container bottle body of this position is the biggest with the distance that the packaging film was separated, the cutter can go deep into certain distance in the packaging film for guarantee that the packaging film in the corner can be cut off completely. 2. In the height direction of the bottle packaging material, a certain distance is still left between the cutting position and the top surface of the bottle packaging material, so that the cut upper surface plastic film is buckled above the container bottle like a cover, and the plastic film cannot be turned upwards and loosened to cause incapability of cutting in the film cutting process.
Specifically, in this embodiment, the remaining uncut connecting edges are the long edges of the bottle wrapper, but in other embodiments, the remaining short edges may be the connecting edges, which are not limited herein and can be flexibly adjusted according to the layout requirements of the production line on site.
Second, turning film
After the packaging film 120 is cut, three sides of the top film and the bottom film except the connecting side 130 are cut, and the side of the top film opposite to the connecting side 130 is a release side 140. Referring to fig. 5 and 6, the method for turning over the film includes:
(1) the top of the film clamping mechanism 330 is provided with a translation electric cylinder 310 and a lifting electric cylinder 320 which are orthogonally arranged, the translation electric cylinder 310 drives the lifting electric cylinder 320 to longitudinally move in the horizontal direction, and the lifting electric cylinder 320 drives the film clamping mechanism 330 arranged at the bottom of the lifting electric cylinder 3210 to downwards adjust to a position close to the uncovering edge;
(2) the position of each film clamping chuck 335 in the transverse direction of the bottle packaging material 100 is adjusted to be opposite to the uncovering edge 140 through the mutual movement of the linear guide rail 332 and the chuck mounting plate 333, under the driving action of the film clamping cylinder 334, the film clamping chucks 335 at least clamp the two ends and the middle of the uncovering edge 140,
alternatively, the first and second electrodes may be,
the position, close to the uncovering edge 140, of the top film is adsorbed by a vacuum chuck, so that the uncovering edge of the top film is adsorbed and clamped;
(3) the lifting cylinder 320 is controlled to be lifted to a certain height, and then the translation cylinder 310 is controlled to move in a direction towards the side of the uncut connecting edge 130, as shown in fig. 6, so that the cut packaging film is turned over.
Third, bottle membrane separation
The top surface of the bottle packing material after the film overturning process is completely opened, and then the bottle is pushed out from the bottom film by adopting a bottle pushing mechanism, so that the container bottle and the packaging film can be completely separated, and the separated packaging film can be pushed out and recovered at one time. The packaging film is opened by the three-side film cutting method, the cutting route is shorter than that of circular cutting, and the important point is that the cut packaging film still belongs to a whole connected together and can be removed at one time.
Referring to fig. 7, the unpacking process of the whole plastic film bottle packaging material in the unpacking machine by installing the opening apparatus for outer packaging of containers according to the present invention will be described.
Firstly, the bottle packaging material moves to the tail end of a track under the drive of a bottle feeding track 410 along the arrow a direction, after the bottle packaging material is detected in place, the bottle packaging material is pushed to a film cutting station 400 by a bag pushing mechanism 420, a limiting device (not shown) is arranged on the side surface of the film cutting station 400 to position the bottle packaging material, a vacuum sucker group at the bottom of the position adsorbs and fixes a bottom film of the bottle packaging material 100, and the bag pushing mechanism can be an electric cylinder or an air cylinder;
then, at a film cutting station, a film cutting manipulator 212 is arranged, a film cutting tool is arranged at the driving end of the film cutting manipulator 212, three sides of the bottle packaging material are cut according to a film cutting path shown in fig. 3 or fig. 4, after the film cutting is completed, two short sides and a packaging film of one long side of the bottle packaging material are cut, and a top film and a bottom film of the other long side are kept connected into a whole;
then, in the direction of an arrow c, the packaging material conveying mechanism 500 drives the bottle packaging material with three cut sides to move to a plastic film separation station, when the bottle packaging material is close to the bottle film separation station, the film clamping chuck of the film clamping mechanism 330 clamps the uncovering edge, and in the process that the bottle packaging material continues to move to the film separation station, the cut long edge of the bottle packaging material rotates around the other uncut long edge to be opened, so that the top film is uncovered;
then, the packaging material conveying mechanism 500 sends the bottle packaging material into the plastic film separating mechanism 600, a bottle receiving plate (not shown) and a film separating platform 610 arranged in parallel above the bottle receiving plate are arranged in the plastic film separating mechanism 600, and a platform opening for the bottle receiving plate to pass through upwards is formed in the film separating platform 610; the medicine bottle moves and carries mechanism 700 and drives medicine bottle and moves and carry frame 800 and descend to and connect a certain distance of bottle board, along arrow d direction, is located the jacking cylinder (not shown) that connects bottle board bottom and rises, will connect the bottle board and place the container bottle that connects on the bottle board and upwards push away to branch membrane platform 610 top, and at this moment, the basement membrane is scraped through the film scraping claw of locating platform opening edge, stays and divides the membrane platform bottom.
