[0014] The travelling-lifting means 5 comprising a first translating means 7 is
assigned to receive, support and move in the first carrying direction the package, i.e. the pallet B and the overlying load S.
[0015] The travelling-lifting means 5 also includes lifting means 9 assigned to move vertically the first translating means 7, the pallet B and load S between the three states at different heights or units.
[0016] In particular the lifting means 9 places the first translating means 7, the pallet B and the load S in a first lowered state, shown in Fig. 2, in which first translating means 7 is aligned to the first carrying direction, and in a lifted state, shown for example in Fig. 3, wherein the grooves of the pallet B are at a certain predetermined height.
[0017] The travelling-lifting means 5 is also equipped with a third element
consisting of a second translating means 21 having a second carrying direction D2 virtually horizontal and inclined, preferably 90°, with respect to the first carrying direction.
[0018] The above mentioned lifting means 9 is also assigned to put the first
translating means 7 to a third height that corresponds to a second lowered state, lower than the first and shown in Figs. 5 to 7, and wherein first translating means 7 is lower than the second translating means 21 such as to allow the first translating means 7 itself to deposit a pallet B on the second translating means 21.
[0019] In said second lowered state the second translating means 21 can transfer the pallet that has been transferred from the first translating means 7 to a second carrier means 23 adjacent to a travelling-lifting means 5 side.
[0020] The second carrier means 23 is coplanar and aligned to the second
carrying direction for receiving and removing from the second translating means 21 of the means of travelling-lifting means 5.
[0021] The machine 1 is also equipped with a drive means 13 having a plurality of rod means 15 parallel to the second carrying direction and kept by the drive means 13 at a height or altitude equal to the predetermined height of the grooves of the pallet B in the lifted state.
[0022] The composite package is placed on the first carrier means 3 with an
orientation such that the grooves G of the respective pallet B are orthogonal to the first carrying direction and, especially, parallel to the second carrying direction and to the rod means 15; then when composite
package is in the lifted state, each rod means 15 is aligned with a corresponding groove G of the pallet.
[0023] The drive means 13 is assigned to move the rod means 15 parallel to
themselves between a state of total disengagement and a state of engagement in the grooves G of the upper pallet, underlying the load S.
[0024] The rod means 15 consist of a plurality of elongated elements having a length equal or greater than the grooves G one and square or rectangular cross sections inscribed in the corresponding sections of the grooves where each groove corresponds to one of those elements which are mutually arranged for the insertion in the respective grooves, between the pallet and the load.
[0025] The rod means 15 are made of steel and their surface is provided with anti-friction treatment or coatings to facilitate the engagement and disengagement of the rods that can get in touch with the pallet, the load and against film or stretch film wrapping.
[0026] The machine 1 also comprises a winding means 19 for packaging
materials such as films or stretch wrapping, for example orbital with horizontal axis, assigned to wind up at least the two horizontal faces and two lateral faces of the load S supported by the rod means 15.
[0027] The winding means 19 of the machine 1 comprises a reel means or a
rotation shaft for a reel of a film wrapping material F.
[0028] Such reel means is slidable along an annular rail means 25 for describing by effect of its motorized drive, a rotary orbital motion about a rotation axis coincident with the main geometrical axis of the annular rail means 25 and, as the geometrical axis passing through the centre of the annular rail means and perpendicular to the geometric plane defined by the latter.
[0029] This rotation axis is horizontal and is approximately incident to the central area of the load in the lifted state.
[0030] The annular rail means 25 is mounted on a set of trucks sliding along two straight guide means 27 for engaging, travelling and disengaging the load area in the lifted state.
[0031] Preferably, the geometrical rotation or longitudinal axis of the reel means, the annular rail means 25 and the longitudinal axis of the guide means 27 and the rod means 15 are parallel to the second carrying direction.
[0032] The reel means is preferably provided with a controlled brake so as to ensure a homogeneous film tensioning or stretch wrapping around the load. Alternatively, the invention provides that the winding means adopted in the machine for coating film of two side faces vertical and the two horizontal faces of the load may be different from what is shown and described above and that it can also be of a known type.
[0033] The machine 1 comprises a third translating means 31 exit on the side of the travelling-lifting means 5 opposite to the first carrier means 3 and aligned to the first carrying direction of the latter to receive from the first translating means 7 and move up to a state of the package consists processed by the machine.
[0034] The machine comprises a feeding carrier means 33 on the side of the travelling-lifting means 5 opposite the second carrier means 23 and aligned to the second carrying direction of the second translating means 21 for supplying travelling-lifting means 5 with replacement pallet, with substitute support means or preferably with template means housing a support means set.
[0035] Each template means 35 is equipped with a set of concave housings for removably accommodate a support means A set.
[0036] The support means A can be provided with projecting and concave feet and gluing upper surfaces and be made of plastic materials, such as recycled, of wood and metal derivatives.
[0037] The machine also includes gluing means 37, schematically shown only in Fig. 6, placed for example between the travelling-lifting means 5 and the feeding carrier means 33 or above the latter. The gluing means 37 are assigned to apply an adhesive means, for example thermal - activated glue, double-sided tape or the like, the gluing surface of the upper face of the support means A or to activate an adhesive means already applied and present on the surfaces to be glued of the support means A.
[0038] Preferably the first carrier means 3, the first translating means 7, the second carrier means 23 and the third translating means 31 are of the chain and/or belt type; the second translating means 21 and the feeding carrier means 33 are preferably of motorized rollers type; the lifting means 9 is preferably of pantographs type.
[0039] The drive means 13 comprises a type of stand or supporting frame,
preferably having a yieldable connection, the rod means 15. The invention provides that the stand or frame can be equipped with adjustable sockets for the rod means 15 provided of interchangeable type so as to adapt its position and type to different types of pallets with different upper grooves.
[0040] The stand or frame of the drive means 13 is provided with base sliding trolleys, due to associated drive motors, along track means rectilinear and parallel to the second carrying direction.
[0041] The motors and drives of the machine 1 are controlled and activated by control means preferably digital electronic, of the programmable type.
[0042] A variant of the invention provides that the template means is adjustable to adapt the mutual distance between the seats of the support means to the measures of the load base. Furthermore the template means can be provided with interchangeable or adjustable seats to accommodate different support means types.
[0043] The variant of Fig. 15 provides that the rod means 15 are constituted by a set, for example two, of elongated plate-shaped elements having a length equal or greater than the maximum of the pallet and flattened rectangular cross-sections for the sliding insertion between the pallet and the load. This variant is also suitable for pallets with the upper face completely flat and free of grooves.
[0044] Even the elongated plate-shaped elements are made of steel and their surface is provided with anti-friction treatment or coating. The tip of these plate-shaped elements can be bevelled or tapered, for example the upper face of these elements may be flat or almost on the tip and the lower face may be joined with an inclined plane or a bevel at the upper face.
[0045] The variant of the machine of Figs 16-20, which is shown with the rod
means of Fig. 14 but which can be fitted with plate-shaped ones of Fig. 15,
comprises two lateral pressing means 51 plate shaped, facing, vertical, perpendicular to the first carrying direction and for example made of two flat steel plates with the outer faces optionally coated anti-friction material.
[0046] The two side pressing means 51 are connected to a respective first
support means 55 by first actuator means 53, for example pneumatic or hydraulic cylinders, for mutual approaching and removing of the side pressing means 51. The first support means 55 can be, for example, of a portal-type vertical or inverted U-shaped frame placed on the side of the drive means 13 with respect to the travelling-lifting means 5 or place between the travelling-lifting means 5 and the drive means 13. The first support means 55 holds the side pressing means 51 at height of the load S in the lifted state by the lifting means 9 of the composite package C.
[0047] The first actuator means 53 moves away the two side pressing means 51 to allow, without interference, the load S lifting between them and approach them to the abutment with the side faces of said load S.
[0048] Immediately prior inserting of the rod means between the pallet and the load, or before separating the pallet from the load supported by the rod means, the pressing means 51 are placed in abutment to the lateral faces of the load; thereby and particularly if the load is not so stable, for example consisting of light and/or yielding boxes, it is avoided that the stresses due to the inserting the rod means, particularly those consisting of elongated plate-shaped elements, at the pallet separation, or due to stresses caused by winding the film can cause shifting or load falling down.
[0049] At the end of the winding the first support means 55, which is equipped with respective sliding means in the second forward direction and drive means, movable with respect to the load obtaining the unthreading of the pressing means 51 from the side film wrapped around the load.
[0050] The machine of this variant also comprises a front first pressing means 57, vertical, parallel to the first carrying direction and connected, via a respective second actuator means 59 for horizontal translation, to a respective second support means 61 placed on the opposite side with respect to the drive means 13 relative to the first support means 55.
[0051] The second support means 61 holds the first pressing means at the load S height e in the lifted position of the lifting means 9.
[0052] The second actuator means 59 moves the first pressing means 57 in the direction opposite to the drive means 13 to allow the lifting of the load S without interference and towards the drive means 13 to cause the abutment of the first pressing means 57 with a face of said load S parallel to the first carrying direction.
[0053] Said machine comprises a pusher means 63 having a stroke on the order of centimetres or decimetres, fixed to the first support means 55 and acting in a direction parallel to the second carrying direction, towards the first pressing means 57.
[0054] The first support means 55 holds the pusher means at the height of the pallet B in the lifted state of the lifting means 9 to act, in this state, on the pallet B in opposition to the first pressing means 57 obtaining a partial translation of the pallet B with respect to load S forming between them a shoulder guide of the rod means 15 between said pallet B and load S.
[0055] Said machine also comprises a second pressing means 65, parallel and facing the front first pressing means 57 and connected, via a respective third actuator means 67 for horizontal translation, the first support means 55 that holds said second pressing means 65 at height of the load S in the lifted state of the lifting means 9 wherein the third actuator means 67 moves the second pressing means 65 to allow the load S lifting and to cause the abutment of the second pressing means 65 with a face of said load S in contrast to the first pressing means 57 to achieve a complete stabilization of the load.
[0056] One of the possible operation way of the machine 1 object of the present invention and described above, for example can be derived from the method for processing composite package by means of this machine.

This winding means 19 is assigned to wrap a load S or package and comprises a reel means 41 provided with an axle for unwinding a reel of film packaging materials F to wrap the load S or package.
[0060] The winding means 19 is provided with annular rail means 25 which is equipped with an orbital truck 45 assigned to support the reel means 41.
[0061] Such orbital truck 45 is driven by a motor to travel along the annular rail means 25 letting the reel means 41 describing a rotary orbital motion around a horizontal rotation axis and preferably approximately incident with the central area of the load S or package to be wrapped; preferably the load S or the package are supported by a plurality of rod means 15.
[0062] The unwinding axis of reel means, the rectilinear guide means 27, the rotation axis of the orbital motion of the reel means along the annular rail means 25 and possibly the optional rod means 15 are mutually parallel and horizontal.
[0063] Optionally the reel means 41 is equipped with a brake controlled for a

[0065] The guide means 27 are provided with respective sliding trucks 43 driven for example by a motor fixed to the frame and cinematically connected thereto by means of chains, worm screws or other, to travel longitudinally such guide means 27.
[0066] Each sliding truck 43 is connected to and supports the underlying annular rail means 25. The coordinated activation of the motors driving the orbital truck 45 and sliding trucks 43 allows adjusting the pitch of the spiral film winding. The motors of the sliding and orbital truck and possibly the brake are controlled and activated by control means preferably digital electronic of the winding means 19 or of the machine to which are associated.
[0067] Referring also to the machine of the embodiment of Fig. 16, the method also involves, starting from the lifted state in which the composite package (C) is lifted by the travelling-lifting means at a predetermined height, stopping the load side opposite the drive means (13) through the front first pressing means 57, pushing and moving at a distance between 1cm and 30cm only the pallet in a direction concordant with the inserting one of the rod means by means of the pusher means 63 obtaining a shoulder formed by an edge of the lower face of the projecting load from the pallet, in addition the method involves at least acting with the drive means 13 and with the lifting means 9 to bring the tips of the rod means 15, first in contact with the shoulder and then down to penetrate between the lower face of the load and the upper face of pallet laying and support. Said operating method allows inserting the rod means between almost every types of pallet, even without upper grooves, and any load types without damaging it.
[0068] An advantage of the present invention is to provide a machine for composite packages that can wrap it with extensible film also the upper and lower faces of the composite package or the entire package.
[0069] Another advantage is to provide a machine able to maintain the original pallet or to replace it with a different one or with support means.
