Definitions
- the present invention relates to a new wrapping process, with the obvious purpose of providing a pallet with its load of an envelope based on a plastic film or sheets, which conveniently stabilizes said load during subsequent handling of the pallet and / or protect dust and water, a procedure that has been specially designed in order to improve the conditions of wrapping, specifically avoiding breakages in the plastic film and allowing a higher operating speed, with the consequent increase in the performance of the wrapping machine, with significant stretching of the film and its consequent savings.
- the new procedure allows to wrap four or five faces indifferently, using a single reel of film.
- the invention also concerns the machine for the implementation of said process.
- One such solution is to mount the pallet with its load on a rotating platform, while the film supply reel is established laterally with respect to the pallet and is subjected to a vertical displacement movement, so that the plastic sheet is wound helically on the periphery of the load, while the pallet rotates.
- Machines of this type are reflected, for example, in European Patents with application number 91401689.4 and 92401863.3.
- the other solution is to keep the static pallet during the wrapping, to avoid the problems of centrifugal force mentioned above, being the film supplying coil the one that describes a planetary movement around the pallet, while simultaneously it undergoes an alternative movement in vertical direction, as for example happens in the machines that reflect the European Patent with application number 90402027.8 or the PCT with publication number WO 90/06261.
- This second type of machines structurally much more complex than those of the first type, and consequently much more expensive, and that due to its large turning diameter, generates large inertia due to the weight of the mobile elements, which force a very large structure and reinforced. It also presents and as a fundamental problem, which is also extended to machines of the first type, a high risk of breakage for the film because the dragging movement of said film is in both cases circular and constant, which brings with it that "pulls" occur in said film in correspondence with the coats that it suffers when reaching the corners or vertical edges of the load, so that in correspondence with said edges, surges and stretching are generated that generate the risk of breakage which has just been mentioned.
- the method of the invention consists in subjecting the film bobbin support head to a cyclic movement around the pallet with its load, but with the special feature that said head describes a path permanently parallel to the contour. of the pallet. More concretely in each cycle or turn of the coil around the pallet, four perfectly rectilinear displacement sections are defined, parallel to the four faces of the pallet, related to each other through orthogonal inflections, in correspondence with the vertical edges of said pallet. pallet, that is to say that in front of the circumferential trajectory of the head in the classic procedure, with the method of the invention said head describes a rectangular path, all this so that the output voltage of the film of said head is constant throughout the wrapping.
- the machine on which the object of the The invention incorporates, in lateral arrangement with respect to the static location area of the pallet, a robot provided with an articulated arm to which the carrier head of the film supplying coil is directly or indirectly connected, said robot having a program that allows it Describe the cyclic movement of the rectangular path of constant velocity mentioned above.
- the robot itself can also supply the coil-holder head with the necessary vertical movement, so that the film winding occurs helically, or this vertical movement can be achieved by coupling the robot's articulated arm to the end of a vertical guide on which in turn the bobbin head will move.
- the use of one or the other system, or the combination of the two, are used according to the maximum height of the pallet to be wrapped.
- the bobbin head is provided with tilting measurements that allow it to adopt an inclined arrangement, in an upper limit situation, for the wrapping of the upper face of the load established on the pallet, that is, for what is commonly called the "fifth face" wrapping.
- Figure 1. It shows a schematic representation on the upper floor of a baler machine, in which, by means of the representation of several positions for the film supply head plastic, the essentiality of the process of the invention is appreciated.
- Figure 2. Shows, according to a general perspective, a concrete practical embodiment of the schematic machine of the previous figure.
- Figure 1 can be seen as, according to the method of the invention, the pallet (1), with its load remains static, while it is the coil (2) that supplies the film it is the one that moves around the pallet (1), but doing it with a rectangular path (3) in accordance with the pallet section (1), so that the head (4) supporting said coil (2) describes around the pallet (1) a path in which four straight sections are defined, parallel and close to the respective faces of the pallet (1), related to each other by orthogonal couplings in correspondence with the vertical edges of the pallet
- This special mobility of the coil (2), and more specifically of the head (4) on which the coil (2) is implanted, is achieved with the collaboration of a robot (6) provided with a multiple and articulated arm (7) , at whose free end (8) the head (4) is fixed, so that said robot (6) is assisted by a properly designed program, the movements of the head (4) around the pallet (1) mentioned above are achieved.
- the robot (6) can exclusively generate the perimeter movement of the head (4) around the pallet
- the head (4) may be directly fixed to the free end (8) of the multiple arm (7) of the robot, in which case said robot (6) must simultaneously supply the head with both movements, the annular movement (3) around the pallet (1) and the parallel and complementary vertical displacement of said head (4).
- a pair of drums or stretching rollers are established (12), both motorized, considerably close to each other, as shown in Figure 1 and with different and adjustable speeds, to allow to regulate in turn the degree of stretch for the film depending on its characteristics.
- the hole logically increases, and can be extended uncontrollably with Conventional systems to cause the film to break, while the rollers (12), of the invention when determining a very small stretch space, do not allow time for the "expansion" of said holes, considerably limiting the risk of breakage. .
