    [0001]
    [0002] Wrapping machine for palletized loads.
    [0003]
    [0004] Technique sector.
    [0005]
    [0006] The present invention is applicable in the packaging sector and more specifically in the equipment used to wrap palletized loads with plastic film.
    [0007]
    [0008] State of the prior art.
    [0009]
    [0010] In the state of the art, palletized load wrapping machines are widely known, comprising, in general: a platform for supporting the palletized load to be wrapped; a vertical column located behind the platform and on which a plastic film dispensing device is mounted, in charge of wrapping the palletized cargo positioned on the platform; and a control automaton that controls the operating parameters of the machine.
    [0011]
    [0012] To wrap a palletized load, it must be positioned on the platform of the wrapping machine, using a forklift. The main problem with this operation is that when the truck driver is behind the palletized load, he cannot see the distance between the front end of the load, or the pallet that supports it, and the vertical column of the wrapping machine, which makes it difficult to position the load correctly on the wrapping machine platform.
    [0013]
    [0014] This problem is further complicated when working with loads and pallets of different dimensions. When the load is at a high height, it further limits the visibility of the driver, and in the event that you cannot see even the vertical column of the wrapping machine, you will also not have a reference for the lateral centering of the load with respect to the platform.
    [0015]
    [0016] The applicant of the present invention is unaware of the existence of antecedents that allow satisfactory resolution of the problems raised.
    [0017]
    [0018] Explanation of the invention
    [0019] The wrapping machine for palletized loads, object of this invention is of the type described in the preamble of the independent claim; comprising a support platform for the palletized load to be wrapped; a vertical column located behind the platform and on which a plastic film dispensing device is mounted, in charge of wrapping the palletized load positioned on the platform and a control automat.
    [0020]
    [0021] According to the invention, this wrapping machine comprises a device indicating the position of the palletized load during its approach to the vertical column and its placement on the support platform to solve the problems exposed.
    [0022]
    [0023] Said device comprises a control unit to which are connected: - vertically spaced front proximity sensors, located behind the platform and which detect the front approach of the palletized load to the vertical column; - an indicator light located in an elevated position in relation to the vertical column and / or an acoustic indicator; said indicators providing visual information and / or audible information, changing as a function of the signals provided by the sensors about the proximity of the palletized load to the vertical column.
    [0024]
    [0025] Said control unit is provided with an on, off and selection command for the acoustic and / or light operating mode of the signaling device.
    [0026]
    [0027] With the characteristics indicated above, when the forklift driver advances to position the palletized load on the platform of the wrapping machine, the sensors detect this load and, as it approaches the vertical column, cause the emission of signals Luminous and / or acoustic that change as the palletized load approaches that vertical column.
    [0028]
    [0029] This allows the forklift driver to have reliable signals to correctly place the palletized load on the platform without risk of colliding with the vertical column or any other element of the wrapping machine.
    [0030]
    [0031] Preferably, the indicator light is arranged at a high height with respect to the vertical column, which allows the forklift driver to display said indicator light when the load to be wrapped does not have an excessive height. In this case, the operator can select by means of the control unit command an operating mode only with light indications.
    [0032]
    [0033] If the palletized load to be wrapped has a height that prevents the truck driver from displaying the indicator light, the driver can choose the operating mode of the acoustic indications through the command of the control unit. an adequate acoustic reference to correctly position the palletized load on the platform.
    [0034]
    [0035] In accordance with the invention, the control unit of the indicating device is suitable for detecting the rotation of the platform and automatically turning off the light and acoustic indications of the indicating device when the wrapping machine is in operation.
    [0036]
    [0037] According to the invention, the control unit, the front proximity sensors and the acoustic and / or light indicators of the signaling device can be mounted in a specific housing, fixed to the vertical column, or integrated into the vertical column of the machine. wrapping machine.
    [0038]
    [0039] In an embodiment of the invention, the indicator light comprises a series of light elements forming overlapping horizontal bars, which are selectively illuminated in an orderly manner, depending on the signals provided by the front proximity sensors, as the palletized load approaches to the vertical column.
    [0040]
    [0041] In this invention, it is provided that the wrapping machine can additionally incorporate at least one lateral proximity sensor, mounted on a pole located on one side of the platform and connected to the control unit.
    [0042]
    [0043] The mission of this lateral proximity sensor is to facilitate the lateral centering of the pallet with respect to the platform. In this case, the light indicator comprises a series of light elements arranged in a cross, which are selectively illuminated based on the signals provided by the front and side proximity sensors, indicating the level of centering of the palletized load with respect to the platform.
