Definitions

  • the invention refers to a completely electric modular device, of small size, suitable for coupling to banding machines and that automatically performs the film clamping operations for the start of the wrapping cycle and the welding and cutting of the film at the end of the wrapping cycle.
  • the sector of the technique in which it is included is that of the wrapping machines.
  • the entire wrapping cycle is carried out automatically, although, both the beginning of the cycle, hooked from the film to the pallet, as well as the end of the cycle, welded and cut of the film, has been done so manual with the inconveniences that in time and security suppose.
  • the ES2171033 patent also refers to a heat-sealing and cutting device but, as with the previous one, it requires pneumatic installation, so it can only be used in fixed banding machines.
  • the device is presented in the form of a kit that can be easily integrated into pre-existing machines, nor does that versatility favor the size of the known devices, all of them too large to be integrated into machines. already existing.
  • the one proposed is small in size, which allows its installation on existing machines with a limited space requirement.
  • the invention object of the present invention relates to a device that, in kit form, can be coupled to semi-automatic wrapping machines.
  • the device comprises:
  • a modular support essentially consisting of a metal plate.
  • a clamping element such as a clamp. We will refer to it as a clamp to differentiate it from the clamping element that is incorporated in the clamping and welding group, although it is understood that it is not limiting its possible executions.
  • a group of soldiers comprising a contrast plate, electrical means for interposing the contrast plate between the film path and the bulk to be angry, fasteners and welding.
  • a cutting element which can be mounted on the soldier group.
  • the wrapping cycle begins with the film attached to the clamp that retains the film since the end of the previous cycle.
  • the wrapping cycle begins as the film around the package to be wrapped is tensioned. After a series of turns, the friction of the tension plastic itself allows the clamp to open without the risk that the plastic will come off the bale.
  • the part of the cycle that corresponds to the bundle itself, is completed when describing the coil not only an orbital movement but also ascending and then descending along the entire height of the object to be wrapped.
  • the device object of the present procedure intervenes again at the end of the cycle as follows.
  • the contrast plate initially in a horizontal position, is raised until it reaches verticality by a spindle driven by an electric motor that forces a three-point interlocking mechanism.
  • the contrast plate Since the contrast plate is within the orbit of the film reel, the contrast plate is trapped by the wrapping film.
  • the film reducer has been narrowing the width of the film by pressure until it is reduced to a width equal to the height of the contrast plate at least at the point where the plate and film coincide.
  • the cutting element such as an incandescent wire, cuts the film at a point between the clamp and the welding element.
  • the contrast plate adopts its horizontal position again and the film, by memory, adjusts to the bale while the clamping and welding group is removed to its initial position.
  • FIGURE 1 shows in explosion different elements of the device and thus look the support plate (1) suitable to fit the platform of a machine (2) with the rack guides (3) on which the clamping and welding group (4) comprising the retaining element (5), the welding element (6) and the cutting element (7), the clamp (8) now open and the contrast plate (9) can also be seen in horizontal position.
  • FIGURE 2 shows different elements of the device mounted and in position to act, so the contrast plate (9) is now vertical and the clamping and welding group (4) is advanced making contact with it.
  • FIGURE 3 explodes the contrast plate (9), the three-point interlocking mechanism (10) that mounts the contrast plate and causes it to change from horizontal to vertical and upside down position, and the mechanism actuation means three-point interlocking comprising an electric motor (1 1) and a housing (12) inside which a spindle runs - which is not shown - and which causes the movement of the three-point interlocking mechanism.
  • FIGURE 4 shows the bobbin carriage -not shown in the other figures- that is usually installed on a rotating arm of the banding machines where the shaft (13) on which the film reel and the retaining roller ( 14) which is surrounded by the film - not shown - before heading to the package to be wrapped and it is precisely at the exit of that retaining roller where the rod is located, really a narrower roller in its central part, in the form of a diabolo (15) that in its downward movement it will wrinkle the film and reduce its width.
  • FIGURE 5 shows another view of the bobbin carriage in which the film width reducing rod (15) is in a lower position than in FIGURE 4, the elements that allow the upward and downward movement of the rod as being a motor (16), a spindle (17) and a guide (18) all of which is mounted on two plates (19) that support allowing this device as a kit to be added to a large number of existing machines.
  • the proposed invention comprises:
  • a contrast plate group comprising a contrast plate (9), means for interposing the contrast plate between the film path and the bulk to be angry (10), (1 1) and (12).
  • a clamping and welding group comprising a clamping element (5), a welding element (6), means (3), (4) to move both elements from their initial position to contact with the contrast plate.
  • a film width reducer comprising a rod (15), a motor (16), a spindle (17), a guide (18) and two plates (19).
  • the means for moving the soldier group comprising a rack and an engine.
  • the wrapping cycle includes the following phases:
  • the film In the start-up phase the film is held by the clamp and the film reel, mounted on an axis (13) in the bobbin carriage and this in turn on the rotating arm of the machine, begins to orbit the film unrolling with the tension supplied by the retaining roller (14).
  • the chiller cycle itself continues with the rise of the coil, together with the bobbin carriage, while maintaining its orbital movement around the package to be packed.
  • the contrast plate During the descent of the coil, the contrast plate (9), until then in a horizontal position, acquires a vertical position thanks to a three-point interlocking device (10) driven by a spindle that rotates by the action of an electric motor ( eleven ).
  • the contrast plate allows to have a surface always the same as the one that triggers the welding element. If welding were carried out on the bale itself, the consistency and the distances would vary depending on the bale content, which would lead to complicated welding and automatic cutting operation. With the contrast plate in an upright position and within the orbit of the coil, the film catches the mentioned plate.
  • the soldier group moves on a rack (3) guide fixed on the support plate.
  • the soldier group includes:
  • a heat welding element (6) that melts the different layers of film by pressing heat against the contrast plate.
  • a cutting element (7) in this case a resistance that cuts the film by temperature.
  • the soldier group is removed and the contrast plate returns to its horizontal position.
