Definitions

  • the present invention relates to an automatic wrapping machine and more specifically to an automatic wrapping machine comprising a cord tying system according to the claims accompanying this specification.
  • An automatic arm wrapper is a type of machine used to wrap plastic film or stretch film products. Compared to manual wrapping, an automatic arm wrapper can wrap products quickly and evenly, reducing the time and effort required to package loads for transit movement or storage. On the other hand, automatic arm wrappers can provide a more uniform and consistent wrap, helping to ensure secure wrapping of products. This reduces the risk of product damage during transport or storage and can help maintain the quality of the packaged product.

  • the present invention consists of an automatic wrapping machine comprising at least one wrapping carriage (37) configured as a consumable feed control structure, in which the consumable used to package the load (38) is housed.
  • This consumable is usually presented in the form of a coil or roll from which the plastic sheet (or other wrapping material in the form of a film) is projected and placed around the load (38).
  • the wrapping carriage (37) also contains the mechanical device that is responsible for forming a cord (39) or rope from the consumable material, which provides stability to the load and is the free piece of material (39) that is then gripped and manipulated by the tying module assembly.
  • the load (38) is placed on a platform (40) that functions as a transport for said load along the packaging line and on which the wrapping process is carried out.
  • the cord tying module is composed of four main subsystems:
  • the tying module (subsystem B) is located away from the load at the start of the cycle. Once the cycle has started, the outer box (1) is brought closer to the load by means of skids (31) in contact with a movement rail (32) which in turn are supported on movement bases (25) and (37). This movement of approach to the load is carried out by means of the actuation of a piston which activates a rod (34) which is responsible for bringing the tying module closer to the load to be wrapped. This movement is carried out until there is contact with the load (38) or until the outer box (1) makes contact with the transport joint (30).
  • the displacement base (subassembly A) is responsible for bringing the tying module (subsystem B) closer to the load (38).
  • Figures 9 to 13 show how the displacement base is coupled to the transport platform (40) such that part of the tying module is introduced at least partially into the platform (40) during operation.
  • the displacement base (subassembly A) is bolted to the transport platform (40) such that its components cannot be separated unless the transport platform is dismantled.
  • the displacement base (subassembly A) is located below the transport platform (40) with supports independent of it and its structures, although associated, are not fully integrated.
  • the tying module is located on an independent platform placed in front of the transport platform. This platform, in the initial or rest position, is at a lower level than the load or the upper plane of the transport included in the line. This platform is equipped with motorized or pneumatic action mechanisms that allow it to move upwards, placing it at the same level as the load or above the upper plane of the transport, allowing it to perform maneuvers without being integrated into the transport.
  • the control of this system is carried out by controlling the time required for the outer box (1) to come into contact with the load (38) placed on the transport platform (40) of the line.
  • This system can be implemented by means of different practical embodiments: (a) the displacement of the base is carried out by means of skids placed at the bottom of the outer box (1) of the tying module and whose control of the distance to be travelled to the load is carried out with a predetermination of the time required to make the journey; (b) the displacement of the base is carried out by means of skids placed at the bottom of the outer box (1) of the tying module and whose control of the distance to be travelled to the load is carried out with the placement of one or more sensors that measure the distance between the load and the outer box (1) of the tying module; and (c) the displacement of the base is carried out through skates placed in the lower part of the outer box (1) of the tying module and whose control of the distance to travel to the load is carried out with the placement of one or more pressure sensors that are stimulated when
  • the tying module (subset B) is installed on or in front of end-of-line conveying systems (40).
  • this conveying platform (40) is made up of metal rollers connected to a traction system that makes them rotate and consequently advances the load through the packaging line.
  • the conveying platform (40) does not contain rollers, but rather belts that are also divided by one or more mechanical systems to achieve a cyclical movement and advance the load through the packaging line.
  • the system can be installed on both sides of the conveyor, allowing up to two modules to operate at the same time on machinery that has more than one wrapping carriage, in order to shorten cycles and increase production. As many ties as the user desires can be made during the wrapping process.
  • the operation of the cord tying system is independent of the size of the load.
  • This movement can be activated through a remote control, from the screen of the machinery or automatically taking the commands from a recipe previously programmed in the equipment.
  • the cutting clamp (subassembly D) and the clamping clamp (subassembly C) are deployed, which are responsible for holding the free end of the film cord before, during and after wrapping each pallet.
  • the deployment of either of these two subassemblies can occur at any time while the outer carriage (1) is approaching or moving away from the load in order to optimize production times.
  • the clamping clamp (subassembly C) holds the cord and approaches the load.
  • the wrapping machine with its wrapping carriage (37) proceeds to start the packaging cycle, placing at least one turn of material on the load so that the cord overlaps the film and the cord (39) dispensed by the wrapping carriage is kept between a film of material and the load itself.
  • the clamping gripper opens by activating a pneumatic cylinder (4), releases the end of the cord and retracts into the outer box (1) moving away from the load so that the module does not interfere with the wrapping process.
  • the wrapping process then continues according to specifications or production needs.
  • the wrapping carriage assembly forms a new cord that wraps around the load at least once.
  • the wrapping carriage with the cord continues the determined wrapping cycle by depositing at least one rope of film or cord in front of the dolly (21), so that it is between a cord (39) and the load (38) being wrapped.
  • the sub-assembly C or clamping clamp is deployed so that it is next to the sub-assembly D and in front of the cord (39).
  • subassembly C does not press or deform the cord (39), allowing it to maintain its integrity and the tying process to have greater stability and repeatability.
  • the wrapping carriage (37) with the cord (39) continues the determined wrapping cycle by depositing at least one cord (39) in front of the dolly (21), so that it is between the cutting clamp (19) and the upper part of the dolly (21), and in front of the subassembly C so that it is between the cutting clamp (19) and the cord retention clamp base (16).
