Definitions

  • the invention refers to machines for wrapping usually palletized loads with extendable and pre-stretched film so as to fix the said loads on the support pallet and impart to the whole assembly a sufficiently rigid, fixed, stable and protected condition, suitable for safe movement of the said palletized loads both during transportation and during storage in protected environments or also in external areas.
  • the invention refers to the ring machines which are described in the document WO 2007/071593 in the name of the same applicant and are schematically shown in the top plan view of Figure 1 of the accompanying illustration and which are referred to by this name since the carriage A with the reel B of extendable film and with the pre-stretching rollers C is mounted on a ring D rotatably supported by wheels E mounted on a horizontal structure which is in turn supported, with the possibility of being raised and lowered by special guiding and movement means, by a gantry structure (also not shown).
  • the palletized load Z to be wrapped is positioned in the centre of the ring D and the leading end of the film supplied by the pre-stretching rollers C is initially retained by a gripper situated alongside and at the bottom of the load Z.
  • F denotes the drive unit which via the belt drive G performs rotation of the ring D with the carriage A and which is mounted on the same structure which carries the support wheels E and which is raised and lowered in synchronism by the associated drive unit (not shown) so as to ensure that the turns of extendable film wrapped by the carriage A around the load cover the said load and the associated support pallet over their entire vertical extension with a helical wrapping composed of several superimposed turns.
  • the film B1 unwound from the reel B is pre-stretched by the pair of pre-stretching rollers C which rotate at different speeds with a predetermined and constant speed ratio and the said film is wound with the correct tension onto the load Z, making use of the elastic memory of the said pre- stretched film so as to ensure that the latter forms a wrapping which holds the load in position with uniformly distributed compression characteristics suitable for the load in question.
  • the speed of rotation of the carriage A around the load Z to be wrapped is such that the pre-stretched film is deposited on the load to be wrapped without undergoing further pre-stretching as a result of co-operation with the load which thus may also consist of delicate products and may remain correctly stacked on the pallet even without the presence of a top load-pressing device.
  • the said speed of rotation of the carriage A around the load Z and the overall speed of the pre-stretching rollers may be such that the film leaving these rollers may be further stretched during cooperation with the load Z.
  • the drive unit H may advantageously consist of a variable speed reducer, the input of which, via a positive drive N, is actuated by the same rotational motor F of the main ring D and which is equipped with a servo control unit H1 so as to be able to vary the output speed of the said variable speed reducer and, together therewith, the overall speed of rotation of the pre-stretching rollers C, for variation of the quantity of pre-stretched film supplied by the latter, under the control of any suitable means designed to perform this speed variation in relation to the dimensions, form and/or other characteristics of the load Z to be wrapped, so as to keep the longitudinal tension of the film wrapping the said load Z at predefined and sufficiently constant values.
  • variation of the output speed of the variable speed reducer H and, together therewith, the overall speed of rotation of the pre-stretching rollers C may be performed automatically using management software which takes into account the characteristics, form and dimensions of the load Z to be wrapped which are introduced from time to time manually and/or using self-learning means into the processor which controls the driving and regulating units F and H1 of the machine.
  • adjustment of the output speed of the variable speed reducer H may be automatically performed using a jockey wheel P which is located on the carriage A and drives the film leaving the pre-stretching rollers C and which has, associated with it, a sensor and means which detect the variations in the tension of the film supplied to the load as a result of the non-cylindrical shape and/or the non-centred position of the load Z and which transmit a modulated radio signal which is proportional to the said variations in tension and received by radio receiver means located on the frame which rotatably supports the ring D and which interact with the machine processor so as to modulate conveniently operation of the server control unit H1 so as to supply a greater or smaller amount of pre-stretched film onto the zones of the load which project and/or are eccentric to a greater or lesser degree, so as to keep the tension of the said wrapping film at predetermined and sufficiently constant values, the said radio transceiver means being powered by small rechargeable long-life batteries.
  • a first solution may consist in providing coupling devices at the two outputs which convey the driving power to the ring of the machine and to the pre-stretching rollers so that, by deactivating these couplings, with the ring at a standstill and the pre-stretching rollers stopped, the main motor of the machine may remain active so as to allow the necessary adjustment of the output speed of the variable speed reducer via the associated servo control unit.
  • the variable speed reducer is replaced by a drive unit separate from the unit for rotating the ring of the machine, and the motor of this unit and the motor for rotating the pre-stretching rollers are actuated using an electric shaft connection and by means of suitable software.
  • the jockey wheel P may be eliminated and the tension of the film on the load during wrapping may be controlled by the said software into which data relating to the characteristics, form and three-dimensional parameters of the load to be wrapped will be introduced from time to time.
  • the present patent application is intended to protect the latter solution both for the specific ring machines according to Figure 1 and for all the wrapping machines which have independent electric motors for rotating the pre-stretching rollers and rotating the reel of film about the load or the load about its axis and about the reel of film in a static position, as will be described more fully below.

  • the machine is set to perform automatically the following operations for adaptation to the new working requirements: the couplings 20, 120 are opened and the motor F remains active so as to operate the variable speed reducer H, while the associated servo control unit H1 is activated in order to modify the output speed of the said variable speed reducer and adapt it to the new working requirements.
  • the couplings 20, 120 are closed again and the motor F is stopped pending reactivation for the start of a new working cycle.
  • the wrapping machine according to the said solution shown in Figure 2 or in accordance with that stated further below with reference to the same Figure 2a may be without the jockey wheel P according to Figure 1 or may be equipped with such a device also of the static type or a sensor, no longer with proportional functions, but with functions of the ON-OFF type only, for the sole purpose of detecting the continuity of the film being fed to the load to be wrapped and for processing a machine stop command should continuous feeding be interrupted.
  • the said continuity sensor where present, may be provided with an independent power supply and may communicate with external means by means of radio frequency, ultrasound or other type of wireless connection, as already mentioned in the patent application cited in the introduction to the present description.
  • Means may be envisaged for temporarily deactivating the operation of said sensor, where present, at any time during the normal operating cycle of the machine should the tension of the film downstream of the pre-stretching rollers become slack, for example during the start- of-cycle stages, when the film is retained by the gripper Q and the tension of the film on the load to be wrapped is minimal.
  • the annular type drive L which indirectly performs rotation of the pre-stretching rollers C, according to a solution different from that shown in Figure 2, may be connected to its own drive unit 1 with an electric motor of the electronically controllable type, for example with an asynchronous motor powered by an inverter or motor of the brushless or other suitable type.
  • This motor may, where necessary, be also provided with its own braking means.
  • the drive unit F which performs rotation of the ring D is also of the electronically controlled type and, unlike the drive unit 1 , will be preferably provided in a known manner also with an encoder 2 so as to set correctly the carriage A of the machine in predetermined angular positions at the start and end of the wrapping cycle and so as to perform, during these phases, rotation and stoppage of the ring D with suitable acceleration and deceleration ramps.
  • the motor of the unit F may, if necessary, also be equipped with associated braking means.
  • the motors F and 1 will be controlled by an electronic processing unit 3 which will receive the information from the said encoder 2 and from a device of the known type 4 which detects the correct centred position of the load Z to be wrapped with respect to the ring D of the wrapping machine.
  • the centred location in which the device 4 has been shown with respect to the load Z is a purely non-limiting example and may be greatly modified according to requirements, this device 4 being able to be used alternatively as an end-of-travel control device for the positioning movement of the load in the machine wrapping station and its location may be modified manually or automatically depending on the size of the said load Z to be wrapped, as indicated for example by 4' and in broken lines in Figure 2a.
  • the processing unit 3 will now be provided with an extension and with software 103 which may from time to time be configured with characteristics relating to the three- dimensional parameters (width, length and height) of the palletized load Z to be wrapped and with parameters relating to the characteristics of resistance to lateral thrusts and compressibility of the load to be wrapped and therefore the tension characteristics which the wrapping film must and/or may exert on the said load.
  • the dimensional parameters of the load may be introduced into the processing units 3, 103 using automatic means 5 consisting, for example, of opto-electronic barriers and electronically controlled displacement systems and/or digital TV cameras or photographic cameras or may be introduced into it via the same manual programming means 6 which will be used from time to time to introduce into the unit 3, 103 the variables relating to the greater or lesser resistance characteristics of the load and the degree of tension with which the load must be wrapped by the wrapping film.
  • FIG. 6 illustrates in the form of a flow chart operation of the improved machine according to the invention.
  • the central processing unit 3, 103 must be supplied with the data relating to the three-dimensional parameters and the at least plan-view form of the load Z to be wrapped or the pallet on which the said load rests and is arranged, as indicated by block 7, and must also be supplied with the characteristics of the load and the tensioning characteristics of the extendable wrapping film which must wrap it, as indicated by step 8.

  • Step 10 in Figure 6, with regard to that stated in connection with Figures 4 and 5 or also for the sole requirements of the start and end phases of the wrapping cycle, will take into account variations in the angular position of the wrapping reel B with respect to the load to be wrapped or of the latter with respect to the reel in the case where the improvements in question are made to rotating-pallet machines, as described further below and as indicated in the same Figure 6 by step 13.

  • Figure 7, for example shows a typical ring machine in which the carriage A with the reel B of film and with the pre-stretching rollers C is mounted on a ring D rotatably supported by wheels E mounted on a support structure which upon command may be raised and lowered so as to impart to the said ring an axial displacement by an amount proportional to the height of the load to be wrapped which is positioned in the centre of the ring D.
  • F denotes the drive unit which via the belt drive G performs rotation of the ring D and which is mounted on the same structure which carries the support wheels E and which upon command is actuated by another drive unit, not shown, for axial displacement of the ring D.

Abstract

Cette invention concerne un appareil pour machine à banderoler des charges généralement palettisées dans un film extensible et pré-étiré. Ledit appareil est muni de moyens d'entraînement à moteur électrique pouvant assurer une rotation relative, à la bonne vitesse, de la charge à banderoler (Z) et de la bobine (B) de film de banderolage. Lesdits moyens sont également aptes à assurer une vitesse de rotation appropriée des rouleaux de pré-étirage (C), de sorte à fournir une quantité de film pré-étiré en fonction de ladite vitesse de rotation relative. Ainsi, ces machines peuvent être exemptes du galet tendeur classique avec capteur proportionnel (P) positionné en aval desdits rouleaux de pré-étirage (C), destiné à réaliser des variations de la quantité de film fournie par lesdits rouleaux de pré-étirage en fonction des variations de la forme géométrique et/ou de l'agencement décentré de la charge à banderoler (Z), étant donné que cette fonction peut être assurée par une unité centrale de traitement électronique (3). Ladite unité est munie d'une extension et d'un logiciel (103) qui tiennent compte des informations fournies par ledit encodeur (2) et qui sont reliés à des moyens permettant leur configuration périodique avec les variables concernant les paramètres tridimensionnels ainsi que, au moins, la forme, vue en plan de la charge à banderoler et les caractéristiques de déformabilité, de résistance à la poussée latérale et/ou de compression de ladite charge, et donc de la tension avec laquelle le film peut banderoler ladite charge. Pendant le banderolage, lesdits moyens d'entraînement peuvent être actionnés de manière synchronisée via la connexion synchronisée des moteurs électriques associés qui sont conçus pour ce type de fonctionnement.
