Description

Description of the industrial invention entitled:

“Winder device for packing loads by means of a film of plastic material” in the name: ITALDIBIPACK S.p.A. based in: POGLIANO MILANESE (Milan)

★ ★★★★

The present invention refers to a winder device for packing loads by means of a film of plastic material that is unwound from a reel and that is anchored to one end of the load, and wound around it, into continuous turns, so as to create a load containment and immobilization wrapping.

Winding a load, for example a box or one or more packages placed on a pallet, by means of a continuous stretchable plastic film, both to join the various packages of the load together and to protect it is known to the state of the art: in this situation the film engages both the packages and the pallet to allow, at the same time, also safe handling.

In the known winder devices, the plastic film is wound around a load, with or without pallet, by moving the reel of plastic film around it, stationary in the middle of the winding area, or by rotating the load/pallet with respect to the reel, or by performing both operations simultaneously. The film is in any case wound around the load so as to form a series of intertwined and/or overlapping wraps or turns.

A known type of winder devices, both manual and automatic ones, are those that are movable on wheels.

These known devices comprise a column placed on a ground base, a reelholder roller and a platform to receive the load to be packed by resting. Document EP 3070004 in the name of the same Applicant describes a winder device in which the lifting plane is vertically displaceable along the column so that said device can be used both as a winder for packing the load and as a lifter for the load itself.

It is evident that packing the load placed on the platform can turn out complex and tiring and can take a long time, especially if it involves heavy loads that need to be moved on said platform to promote their packing or if it involves loads containing fragile goods that risk breaking with each movement.

Self-propelled winding machines mainly used in the packaging sector for winding, and therefore stabilising the palletised loads with film of stretchable plastic material that is unwound from a reel, are also known to the state of the art. This type of machine (also commonly called a pallet wrapping robot) is configured to rotate around a load to be packed or a stack, following autonomously the contour thereof.

These self-propelled winding machines generally comprise a self-propelled machine body configured to advance in a plane, a lifting device, in the form of a column, rigidly connected to the machine body and configured to move a slide with a reel-holder roll orthogonally to the advancement plane of the machine body, and as safety means for the operator, at least one sensor and/or at least one distance detector configured to detect the distance of the machine body and/or of the lifting device from a stack and to generate a corresponding control signal for the movement of the machine body and a control unit configured to receive command and/or control signals of the movement of the machine body and/or of the lifting device and to generate, on the basis of the received command and/or control signals, at least one driving signal for the movement of the machine body and/or of the lifting device.

The general aim of the present invention is to overcome the aforementioned drawbacks by providing a winder device for packing loads by means of a film of plastic material, preferably stretchable, which facilitates the work of the operator by making manual intervention safe, minimal and not tiring, in particular by limiting the operator's fatigue during the initial step of positioning the load on the rest plane and during the final step of picking up the packed load.

An aim of the present invention is also to provide a self-propelled winder device that can move safely on a plane.

A further aim of the present invention is to make available to the operator a winder device that allows short processing times for the complete winding of the load with the plastic film and for the complete preparation of the load for the purposes of shipping or storage.

A further aim of the present invention is to make available to the operator a winder device capable of guaranteeing a correct packaging, regardless of the shape and size of the load, which can protect it from impacts, atmospheric agents, dust and dirt.

A further aim of the present invention is to provide a winder device whose use is versatile and is little cumbersome when not in use.

In view of these aims, it has been thought to realize a winder device according to claim 1 . In particular, the winder device for packing loads by means of a film of plastic material comprises a load-bearing column constrained at one end thereof to a ground rest baseplate or to a self-propelled machine body configured to advance in a plane, along which load-bearing column a slide provided with at least one reel-holder roller of film in plastic material is constrained to slide. Said device also comprises a platform associated with said slide and movable by rotation around a vertical axis Y, parallel to said column, said platform being configured to receive a load by resting and make it rotate around said vertical axis, the rotation of the platform, together with the unwinding of the plastic film being adapted to coat the load with said plastic film.

It has also been thought to make, according to the invention, a winder device that comprises, in addition to said rotating/rotatable plate, also a load lifting plate.

For the illustration of the drawings, use is made in the following description of identical numerals or symbols to indicate construction elements with the same function. Moreover, for clarity of illustration, certain references may not be repeated in all drawings.

The preferred embodiments are shown in the drawings and will be described in detail below. It must in any case be understood that there is no intention to limit the invention to the specific embodiments illustrated, but, on the contrary, the invention intends covering all the modifications, alternative and equivalent constructions that fall within the scope of the invention as defined in the claims.

Indications such as “vertical” and “horizontal”, “upper” and “lower”, “up” and “down” (in the absence of other indications) are to be read with reference to the operating conditions and referring to the normal terminology used in current language, where “vertical” indicates a direction substantially parallel to that of the gravity force vector “g” and “horizontal” a direction perpendicular thereto.

With reference to the figures, a winder device according to the prior art is shown in figure 1 and figure 2.

The winder device T shown comprises a reel-holder roller 2’ of wrapping material, for example a stretchable plastic film, F, a vertical column 3’, a lifting plane 4’ adapted to receive the load and displaceable up and down along said vertical column 3’, so that the device 1 ’ can be used both as a winder and as a lifter, a baseplate 5’ coupled to the column 3’, which in the illustrated embodiment comprises arms and swivel wheels, but which can have various shapes for example a plate with wheels or the like.

In order to allow this displacement, the column 3’ comprises a C-shaped sliding guide, in which a slider coupled to the plane 4’ slidably engages.

As illustrated in the figures, the reel-holder roller 2’ is associated with the lifting plane 4’ and moves integrally with it along the column 3’.

The reel-holder roller 2’ can therefore be displaced along the column 3’, up and down, so as to bring the reel to different heights and allow the load to be wound with a plurality of intertwined and/or overlapping wraps or turns. As illustrated in figures 1 and 2, the reel-holder roller 2’ and the lifting plane 4’ are rotatably coupled to the column 3’: the roller 2’ and the plane 4’ are therefore displaceable from a position in which the plane 4’ is substantially orthogonal to the column 3’ (figure 1 ), with the longitudinal axis of the roller 2’ perpendicular to the vertical axis of the column and passing through the centre of gravity of the plane 4’, to a position in which the plane 4’ (and thus the roller 2’) is parallel to the column itself (figure 2).

According to a further optional feature, there may be an unwinding roller 21 ’ parallel to the reel-holder roller 2’, which is useful in the operations of winding the film F around the load to keep said film in the correct position and avoid wrinkles.

The winder device 1 for packing loads by means of a film of plastic material object of the present invention is illustrated in figures 3 to 11 .

The device 1 comprises:

- a load-bearing column 3 constrained at one end thereof to a rest baseplate 5 or to a self-propelled machine body configured to advance in a plane, along which load-bearing column 3 a slide 6 provided with at least one reel-holder roller 2 in film F of plastic material is constrained to slide,

- a platform 7 associated with said slide 6 through a support arm 8 and movable by rotation around a vertical axis Y, parallel to said column 3, said platform 7 being configured to receive a load C by resting and make it rotate around said vertical axis Y, the rotation of the platform 7, together with the unwinding of the plastic film F being adapted to coat the load C with said plastic film F. The reel-holder roller 2 of film F in plastic material, preferably stretchable, is of the type known per se to the state of the art.

Thanks to the present device 1 , the reel and the platform 7 can therefore be displaced up and down, to different heights to allow the load C to be wound with a plurality of at least partially overlapping turns of plastic film F.

This winding is carried out by making the platform 7 rotate, as described below.

The load-bearing column 3 in operating condition is positioned vertically, perpendicular to the rest plane e or to the floor.

Said platform 7 is rotatably coupled to an elongated element or support arm 8, i.e. it rotates on said support arm 8, as illustrated by the arrows in figure 3.

The arm 8 is articulated (or rotatably coupled) to said slide 6, i.e. it is oscillatable with respect to said slide 6, as illustrated by the arrows in figure 5, 7 and 8, and is therefore displaceable between a first position in which said arm 8 and said rotatable platform 7 are parallel to the column 3 and a second position in which said arm 8 and said rotatable platform 7 are orthogonal to the column 3.

In particular, when the arm 8 is parallel to the column, it not only makes the device 1 , in a step of non-use, little cumbersome but it makes it possible to release it from the slide 6.

The coupling of the arm 8 to the slide 6 takes place in fact through at least one claw-like element or hook 801 provided on the arm adapted to hook or engage on at least one corresponding pin 601 provided on the slide 6. Obviously it is possible to provide that said hook(s) are provided on the slide 6 and said pin(s) 601 are provided on the support arm 8 of the rotatable platform 7.

The coupling through hooks 801 allows the platform to be easily removed from the device 1 , which will be remain provided only with the reel of plastic film F.

According to a variant not illustrated, the arm 8 can be rotatably coupled to the slide 6 through a hinge.

As illustrated in figure 3, said hooks 801 are positioned on said arm 8 in such a way that when the arm 8 is in its second position, in which said arm 8 and said rotatable platform 7 are orthogonal to the column 3, one end of said arm, opposite to that in which the rotatable platform 7 is positioned, can abut against the lower edge of the slide 6, in such a way that said second position of the arm 8, orthogonal to the column 3 and therefore parallel to the floor (not illustrated), is stable.

As illustrated in Figure 4, two hooks or claws may be provided on the edges or side surfaces of the arm 8 that engage on pins 601 protruding from the surfaces or side edges of the slide 6.

Said second position can be defined as operational as it permits that the load to be packed can be positioned on the rotatable platform 7.

Advantageously, thanks to the hook-like coupling of the arm 8 to the slide 6, which avoids a rigid fixing of said arm 8 with respect to the slide 6, the platform 7 and/or the winder device 1 can be in a non-operating condition where the platform 7 is parallel to the column 3 or even removed (together with the arm 8) from the device 1 .

The winder device 1 is thus easily transportable and displaceable. As illustrated in the exploded view of figure 4, the arm 8, or support frame 8 in the shape of an elongated element, is provided at a first end thereof with means 802, 802’ adapted to allow the rotation of the platform 7 and it is further provided near a second end thereof, opposite to the first one, with said hooks 801 adapted to hook with corresponding pins 601 provided on the slide 6.

Said means 802, 802’ adapted to allow the rotation of the platform 7 consist of known elements such as flanges, bearings, circlips, rotation shafts.

As illustrated in figure 4, said means 802, 802’ adapted to allow the rotation of the platform 7 are positioned on the upper surface of the arm 8, hooks 801 are provided, on the surfaces or side edges of the arm 8 and spaced from the distal edge of the arm , in such a way that when they are hooked to the support pins 601 provided on the slide 6, a portion of the upper surface of said arm 8 can abut, as previously described, against the lower surface of the slide 6, when said arm 8 is positioned orthogonally to the column 3, and the rotatable platform 7 can be used to rotate the load C to be wound with the plastic film F.

Obviously, it is possible to provide that the means allowing the rotation of the platform 7 on the arm 8 are motorized.

For example, it is possible to provide an actuator configured to set the platform 7 in rotation, a control unit configured to command the actuator in managing the start, the stop and the rotation of the platform 7 at a certain angular rotation speed.

In order to allow the sliding of the slide 6 along the column 3, which sliding can be manual or motorized, and to allow the displacement upwards or downwards of the rotating platform 7 on which the load C to be packed with the film F of stretchable plastic material is rested, said load-bearing column 3 comprises a sliding guide 9, which extends, in a vertical direction, along at least part of said column 3, in which guide a slidable slider 10 coupled to said slide 6 engages.

The coupling of the slide 6 to the slider 10 can be fixed, as illustrated in figure 3, or rotatable, as described below.

The sliding slide 9 is preferably “C”-shaped.

The guide 9 preferably extends along the entire length of the load-bearing column 3.

The slider 10 is preferably a carriage, for example with wheels, which moves in the guide 9 and is driven by a drive mechanism, either manual or motorized, provided with appropriate and known mechanical transmissions (belts, chains, toothed wheels or the like).

The reel-holder roller 2 is thus indirectly coupled to the column 3, through the slider 10 and the slide 6.

Therefore, according to a first embodiment, said slide 6 is provided, on one side, with said reel-holder roller 2 of film F in plastic material and with said support arm 8 of said rotatable platform 7 and, on the opposite side constrained to said load-bearing column 3, with means for fixing to said slider 10 for the stable coupling of said slide 6 to said slider 10.

For example, the slide 6 can be riveted to said slider 10.

According to a second embodiment of the present invention, the device 1 also comprises a plane or lifting plate 11 , which is also adapted to receive a load C, said lifting plate 11 being constrained to the slide 6 as described below (figure 11 ).

In said second embodiment, the slide 6 is not fixed in a stable manner to the slider 10 but is articulated or coupled to it in a rotatable manner in such a way that it can also rotate, with respect to the load-bearing column 3, and in particular with respect to the slider 10, between a first position in which said slide 6 and said lifting plate 11 are parallel to the column 3 and a second position in which said slide 6 and said lifting plate 11 are orthogonal to the column 3.

The arrows of figure 7 show the rotation of the platform 7, the oscillation of the arm 8 with respect to the slide 6 and the oscillation of the slide 6 with respect to the slider 10 and therefore to the load-bearing column 3.

Also said plane or lifting plate 11 can be displaceable along the loadbearing column 3 as it is associated with the slidable slide 6.

According to said second embodiment, the slide 6 is provided, on one side or surface, with said reel-holder roller 2 of film F in plastic material and with pins 601 for hooking the hooks 801 of said support arm 8 of said rotatable platform 7 and, on the opposite side (or opposite surface), it is further provided with said lifting plate 11 and means being provided for the rotatable coupling 602 of said slide 6 to said slider 10.

To allow said rotatable coupling, said means 602 provide at least one rotation pin and a guide that articulate the slide 6 and/or the lifting plate 11 to the slider 10, and therefore consequently to the load-bearing column 3.

The slide 6 and the lifting plate 11 associated with it are therefore displaceable between a first position that can be defined as operational or for lifting the load, in which the slide 6, the reel-holder roller 2 and the lifting plate 11 are substantially orthogonal to the column 3 and a second position in which the slide 6, the reel-holder roller 2 and the lifting plate 11 are parallel to the column 3 itself and therefore the load C cannot be placed resting on said lifting plate 11 .

Obviously, blocking or retaining means can be provided for blocking in at least two of the described positions said arm 8 with respect to the slide 6 and/or said slide 6 with respect to the slider 10.

Advantageously moreover as visible in figure 3 and figures 5-7, in both embodiments, the longitudinal axis of the reel-holder roller 2 passes through the centre of gravity of the lifting plate 11 and/or is in line with the load-bearing column 3.

This allows the reel of plastic film F to be positioned centrally to the device 1 and therefore to reduce the plan amplitude of the baseplate 5, without a loss of stability of the device 1 itself on the rest floor.

Obviously, it is possible to provide that the device 1 is provided with several reel-holder rollers, for example associated with the column 3 and/or with the slide 6.

With reference to the figures, figure 3 is a partial view of the winder device 1 object of the present invention and shows a first embodiment in which the slide 6 is stably coupled to the slider 10 that engages in the sliding guide 9, which extends in a vertical direction along said column 3, to which slide 6 the supporting arm 8 of the rotating platform 7 is rotatably coupled. Figures 5 to 10 illustrate partial views of the second embodiment of the winder device 1 object of the present invention in which also the slide 6 is rotatably coupled to the slider 10.

Figure 11 shows a perspective view of the second embodiment of the winder device 1 object of the present invention: in the figure the lifting plate 11 is visible, in a vertical position, i.e. not in use to support a load C, between the slide 6 and the load-bearing column 3. In the first embodiment of the device, said plate 11 is absent and the slide 6 is fixed in a stable manner, for example riveted to the slider 10, so that it can move with it, down and up, along the column 3.

In this second embodiment, said slide 6 provided with means for the rotatable coupling 602 to said slider 10 that allow the displacement of said slide 6 and of said lifting plate 11 between a first position in which said slide 6 and said lifting plate 11 are parallel to the column 3 and a second position in which said slide 6 and said lifting plate 11 are orthogonal to the column 3. Said means may be for example a hinge.

Said slide 6, hinged to the slider 10, can therefore oscillate between the two positions described above.

In particular, figure 5 shows how the lifting plate 11 , placed between the slider 10 and the slide 6 can be kept in a vertical position, i.e. parallel to the load-bearing column 3, i.e. orthogonal to the floor through blocking means 111 , for example bayonet means.

Figures 7 and 8 show how the arm 6 carrying the rotating or rotatable platform 7, can be easily released from the slide 6, by rotating it towards the column 3, that is, by displacing it from the position orthogonal to the column 3 to the vertical position, parallel to the column 3 and by releasing the hooks 801 from the respective pins 601 : in figure 9 the arm 8 is partially released/removed from the slide 6 while in figure 10 the arm 8 and therefore the rotatable/rotating platform are completely removed from the device which is thus only provided with the lifting plate 11 and with the reelholder roller 2.

As illustrated in the figures, the platform 7 is provided on the surface thereof with one or more housings, in the form of holes or elongated slots, for the insertion and/or the sliding by snapping of one or more stop elements (not illustrated) such as pins, wedge elements, V-shaped elements, profiles, sliders or the like that allow to keep the load C in a stable position on said platform 7.

Preferably said housings are provided on the surface of the platform 7 diametrically opposite to allow to stably retain the load C on the platform itself.

The platform 7 can advantageously be provided with a load cell that allows the weight of the load C to be determined.

The platform 7 in the figures is illustrated as a plate or round plate but of course it can have any shape and size to accommodate the load C to be packed.

The rotatable or rotating platform 7 therefore allows that the load C can be rested stably on it, and then by rotation of the platform itself, thus reducing the operator's fatigue, compared to the use of a fixed platform, it can be easily packed by unwinding the plastic film F from the reel. The slide 6 that is slidable along the load-bearing column allows the load to be placed at a height suitable for carrying out the operations of positioning/removing the load C from the device 1 and of packing.

The device 1 object of the present invention is configured to advance in the plane of the floor, and the slide 6 is configured to vertically move a reel B of wrapping material, for example a stretchable film F, with respect to said plane.

The slide 6, slidably connected to said vertical load-bearing column 3, can be suitably motorized so as to allow the vertical movement along said loadbearing column 3. In this way, it is possible to automatically adjust the height of the slide 6 and therewith of the reel-holder roller 2 so as to be able to wind the stretchable film F around loads whose sizes are even very different from one another, positioning said loads C always at an optimal height for packing by the operator.

A handlebar M shaped in such a way as to define a passage for the slide 6, in order not to hinder its vertical translation, can be connected to the loadbearing column 3.

The baseplate 5 that supports the column 3 and rests on the ground can be provided with wheels, preferably swivel wheels.

The wheels can also be driven by a respective independent motor (not illustrated).

According to an embodiment not illustrated, said winder device can be self- propelled, that is, as an alternative to the baseplate 5 it is possible to provide that the load-bearing column 3 is rigidly connected to a self- propelled machine body configured to advance in a plane. Advantageously, in order to increase the safety thereof during use, said winder device 1 is provided with at least one distance detector configured to detect the distance of the machine body or of the baseplate with motorized wheels 5, and therefore of the winder device 1 , from a stack and to generate a corresponding control signal for the movement of the device itself.

The winder device 1 can also be provided with a control unit configured to receive command and/or control signals of the movement of the machine body and/or of the baseplate with motorized wheels 5 and/or of the slide 6 along the load-bearing column 3 and to generate, on the basis of the received command and/or control signals, at least one driving signal for the movement of the machine body and/or of the baseplate with motorized wheels 5 and/or of said slide 6.

Said winder device 1 can comprise a presence sensor, for example ultrasonic or thermal, operationally connected to the control unit and configured to detect the presence of an obstacle within a detection volume surrounding the device, in particular the machine body or the baseplate motorized with wheels 5 which can send a corresponding presence signal to the control unit, in case it detects the presence of an obstacle within the detection volume and/or it can send an activation signal to a light and/or acoustic and/or mechanical signalling device.

A winder device 1 is thus made, which can be displaced manually or mechanically on a plane, which allows positioning the load C to be packed at the desired height, and preferred by the operator, and which allows to set the load in rotation, so that the film can be arranged all around the load C. The film F is preferably flexible and adapts to the shape of the load to cover it and protect it adequately.
