Description

Moving device and winding machine comprising same

Technical Field

The present utility model relates to a moving device designed for handling a travelling assembly of a winding machine for winding a load placed on a rack with a film, and in particular to a moving device intended for moving the travelling assembly closer to or further from the load for handling the load.

To do this, the running assembly is driven after the winding operation is completed, i.e. the moving device starts to approach the load after the load has been wound with a predetermined number of turns of film. The running assembly may be a cutting/sealing/gripping assembly comprising a cutting assembly for cutting the film, a sealing assembly for sealing the film to the film wrapping ring around the load, in particular the outermost (i.e. furthest from the vertical rotational axis of the load) portion of the sealing wrapping ring, and a gripping assembly for gripping the edge of the film to start the wrapping ring of the load as an initial wrap.

Background

Winding machines known in the industry, in particular of the rotary load type supported by a rotary table, use a load on a film wrapping tray comprising a support and unwind assembly matching the wound film roll, stretching the film by rotation of the load about a rotation axis. The rotation of the load about the axis of rotation is related to the movement of the support and unwind assembly in a vertical direction, i.e., generally parallel to the axis of rotation, to apply a predetermined number of rolls of film to the load.

After the winding operation is completed, i.e. after the load on the pallet has been wound with a predetermined number of films, the operating assembly of the winding machine starts to operate close to the load, seals the films to the winding ring away from the vertical axis of rotation of the load, cuts the films and retains the cut films.

The running assembly may include a cutting assembly for cutting the film, a sealing assembly for sealing the film to the film wrapping ring around the load, particularly the outermost (i.e., furthest from the vertical axis of rotation of the load) portion of the sealing wrapping ring, and a gripping assembly for gripping the edge of the film to begin the load wrapping ring as an initial wrap.

A winding machine of known type comprises a running assembly moving device, comprising a connecting portion, rigidly connected to the running assembly, for moving the running assembly towards the load; after the process is completed, the running assembly on the cargo will be removed.

The moving device of the operating component can also adopt an articulated arm.

A disadvantage of the articulated arm mobile device is that the entire mobile device moves the running gear along an arc and in a way that is not predefinable. This means that at least a part of the running assembly, in particular a part of the sealing assembly, may be in contact with an area where sealing is not required, such as a part of the pallet or a turntable where the pallet is located. Thus, sealing the film on the outer wrapping ring does not affect the overall height of the film, but only a portion of the film and the trailing end of the film are not sealed to the loaded outer film wrapping ring. The load on the pallet will therefore be discarded and not placed in the pre-set automated storage warehouse, but rather transported to a inspection station for subsequent contour inspection. The packaging film must then be removed from the waste carrier and subsequently rewound with a new packaging film, which results in considerable material consumption and high production costs.

As an alternative to the articulated arm movement means, the running gear movement means may comprise one or more linear actuators arranged in a direction substantially perpendicular to the load. The or each linear actuator of the displacement means should comprise a cylinder in which a valve stem connected to the piston slides.

Such a displacement device, which consists of one or more linear actuators, has the disadvantage that, because of the very significant amount of space that the hollow body of the one or more linear actuators occupies in the closed or inoperative configuration of the displacement device, the stroke of the valve stem of the displacement device in the open or operative configuration may extend out of the cavity.

Detailed Description

Referring to fig. 1, the present utility model illustrates a mobile device 1 that moves a running assembly 100 toward and away from a cargo placed on a rack 2, such as a pallet, or a rack with roller or chain motion.

The moving device 1 associated with the running assembly 100 should be installed in the winding machine 1000, which is capable of winding the load on the rack 2 with a film for a preset number of turns.

The winder 1000 may include a carriage and winder assembly, not shown, that supports and winds the number of turns of film by relative rotation about the carriage and winder assembly and the load placed on the carriage 2. The relative rotation occurs on a substantially vertical winding axis W.

As used herein, "substantially perpendicular" refers to an axis that is substantially parallel to the gravitational acceleration vector.

For winding a predetermined number of turns of film around the load on the support frame 2, for this relative rotation the device is associated with a support and unreeling assembly in the vertical direction, i.e. substantially parallel to the winding axis.

In particular, the winding machine 1000 may include a rotary cargo model supported by a rotary table. In this case, the winding machine 1000 should include a rotary table for supporting the load placed on the stand 2. In use, the cargo rotates about an axis of rotation that coincides with the perpendicular direction to the winding axis W.

The running gear 100 may be connected to the moving device 1, in particular in a rigid manner, so that near the end of the operation or process of wrapping the load with film, i.e. when a predetermined number of wrapping turns have been applied to the load, the running gear 100 may be moved to a position close to the load in order to perform work on the load.

To perform these operations, and with particular reference to FIG. 2, the present running assembly 100 may include a cutting assembly 110 for cutting the film, a sealing assembly 120 for sealing the film to the film wrapping ring around the cargo, particularly the outermost (i.e., furthest from the vertical axis of rotation of the cargo) portion of the sealing wrapping ring, and a grasping assembly 130 for grasping the film to begin the cargo wrapping ring as an initial wrap.

Thus, operations that the running assembly 100 may perform on the cargo include sealing the film to the portion of the winding ring furthest from the vertical axis of rotation of the cargo; a film shear phase for obtaining film edges and a grasping or holding phase for packaging subsequent loads.

The film is made of an elastic and/or plastic material, such as an elastically stretchable film, which can be used around the cargo and can hold the cargo together in a stable manner. The film, in particular, comprises a heat-sensitive film.

The movement device 1 comprises lever means for supporting the running gear 100 close to or away from the load placed on the support frame 2.

The mobile device 1 further comprises actuation means 12 connected to the lever means for moving the mobile device 1 between a closed configuration C of minimum space and an open configuration a of maximum space.

The drive means 12 are used for moving the lever means relative to the load.

In the closed configuration C, the mobile device 1 is located away from the cargo. In this position, the running assembly 100 is also located away from the load, where it does not interact with the film wrapped load. In other words, the position remote from the cargo corresponds to a position in which the mobile device 1 is fully retracted relative to the cargo.

On the other hand, in the open configuration a, the mobile device 1 is close to or placed around the load, not far from the load when in the closed configuration C; in a location closest to the load, where the running assembly 100 is also located closer to the load, the running assembly 100 may interact with the film wrapped load to perform the above-described operations. In other words, the position close to the load corresponds to the maximum projected position of the mobile device 1 with respect to the load.

The drive means 12 comprises a drive actuator in an assembly, the whole assembly comprising: a cylinder, a hydraulic cylinder and an electromechanical actuator.

The mobile device 1 further comprises a trajectory modification assembly 20 connected to the leverage means for dynamically controlling the leverage means so that the running assembly 100 can follow a linear trajectory at a constant height relative to the cargo as it moves between the distal position and the proximal position.

The linear trajectory is substantially perpendicular to the axis of rotation of the cargo.

With this configuration, the progress of the running assembly at a constant height in the direction of the load is perfectly horizontal, facilitating the identification of the final position of interaction with the load itself (otherwise, for an arc-shaped trajectory of varying height, determining the final contact point of the running assembly with the load would be more difficult or not straightforward).

The linear trajectory obtained by the algorithm of the utility model can determine the height of the running assembly. This avoids the handling of different parts of the load by the operating assembly. In this way, the package, such as during a contour inspection, is not discarded due to being positioned at an outer cargo portion (e.g., at least a portion of the rack) that is not identifiable by the running assembly due to the incorrect height of the running assembly.

The track modifying assembly 20 includes an anti-bar assembly 10 coupled to a lever assembly.

The lever means comprise a first lever means 3 and a second lever means 4, which are rotatably connected to a first articulation element 5 of the mobile device 1, rotatable along a first rotation axis R1 and a second rotation axis R2, respectively.

The first living hinge element 5 is rigidly connected to the running assembly 100 by known means of connection, such as screws and bolts.

In use, the running gear 100 may be moved on the mobile device 1 by moving the first living hinge element 5 along a linear trajectory toward or away from the cargo. In other words, the first living hinge element 5 will also move along a linear trajectory at the same critical height when the mobile device 1 moves between the open configuration a and the closed configuration C.

The first lever device 3, the second lever device 4 and the first movable hinge element 5 support the running assembly 100 close to or away from the load.

The first living hinge element 5 as well as the running assembly 100 can be moved by means of the lever arrangement, the track modification assembly 20 and the drive 12, i.e. in a direction substantially perpendicular to the direction of movement D1 of the load.

As shown in fig. 3, the drive means 12 are designed to exert a pulling and/or pushing action on the lever means in a direction of movement X transversely thereto, the inclination of the first living hinge element 5 relative to the direction of movement X being variable when it is moved in the direction of movement X.

The lever means further comprise a third lever means 6 and a fourth lever means 7, which are rotatably connected to the first fixed hinging element 8 of the moving device 1, rotatable along a third rotation axis R3 and a fourth rotation axis R4, respectively.

The first stationary hinge element 8 remains stationary, i.e. the mobile device 1 is stationary when it moves between the open configuration a and the closed configuration C.

The counter lever means 10, the second lever means 4 and the driving means 12 are adapted to move the first movable hinge member 5 along a linear trajectory so as to maintain a substantially equal distance D between the second rotation axes R2 and to pass through a horizontal plane P, indicated by a broken line in fig. 3, between the fourth rotation axes R4.

Furthermore, the first lever device 3, the second lever device 4, the third lever device 6, the fourth lever device 7 are connected to the second articulation element 9 of the mobile device 1 in a rotatable manner with respect to each other, rotatable along a fifth rotation axis R5, a sixth rotation axis R6, a seventh rotation axis R7 and an eighth rotation axis R8, respectively.

The second movable hinge member 9 is moved, i.e. moved between the open configuration a and the closed configuration C, by means of the lever arrangement, the trajectory modification assembly 20 and the drive device 12, in particular with a variable size trajectory with respect to the load, i.e. a variable size with respect to the horizontal plane P.

In particular, the counter lever means 10 should be rotatably connected to the second lever means 4, so that these counter lever means 10 and second lever means 4 can rotate about a ninth rotation axis R9; the counter-rod means 10 are also connected in a rotating manner to a second fixed hinging element 11 on the mobile device 1, rotatable about a tenth rotation axis R10.

The second stationary hinge element 11 remains stationary, i.e. the mobile device 1 is stationary when it moves between the open configuration a and the closed configuration C.

The driving means 12 are connected to one of the above-mentioned first lever means 3, second lever means 4, third lever means 6, fourth lever means 7 for operating the moving means 1 between the minimum space closed configuration C and the maximum space open configuration a; in the closed configuration, the second rotation axis R2 and the tenth rotation axis R10 reach a minimum distance dmin, and in the open configuration, the second rotation axis R2 and the tenth rotation axis R10 reach a maximum distance dmax.

The first living hinge element 5, the second living hinge element 9, the first stationary hinge element 8 and the second stationary hinge element 11 comprise connection blocks 13, 14, 15 and 16, respectively, each having a substantially parallel shape. For example, each of the connection blocks 13, 14, 15, and 16 may have a square outer shape.

The first movable hinge element 5, the second movable hinge element 9, the first stationary hinge element 8 and the second stationary hinge element 11 may also each comprise at least one connection plate 21a, 22a, 23a and 24a, respectively, mounted on the corresponding connection plate 13, 14, 15 and 16, respectively, each connection plate 13, 14, 15 and 16 and each connection plate 21a, 22a, 23a and 24a being connected to the first lever arrangement 3, the second lever arrangement 4, the third lever arrangement 6 and/or the fourth lever arrangement 7, or the counter lever arrangement 10, the drive arrangement 12, respectively, in an articulated manner.

In the illustrated implementation, the first lever means 3 comprise a connecting rod 3a, the end 17 of which is hinged to a first face of the connecting block 13 of the first living hinge element 5, and the end 18, opposite to the end 17, is hinged to a first face 19a of the connecting block 15 of the second living hinge element 9. In particular, the connecting rod 3a may be connected to the connecting blocks 13 and 15, respectively, so that the first rotation axis R1 and the second rotation axis R5 pass through respective points arranged near the vertices of the respective connecting blocks 13, 15.

Specifically, one end 17 of the link 3a is rotatably mounted between the connection block 13 and the connection plate 21a, and the other end 18 of the link 3a is rotatably mounted between the connection block 15 and the connection plate 23 a.

The second lever means 4 comprise a profiled bar 4a consisting of a first portion 25 of the connecting rod and a second portion 26 of the connecting rod, extending over an angle α of 110 ° to 150 °, in particular over an angle of 120 °. The link first portion 25 and the link second portion 26 are connected to the link region 27, between the link first portion 25 and the link second portion 26, as a common end of the link first portion 25 and the link second portion 26. The link region 27 is hinged to an outer surface 28 of the connection plate 23a on the second living hinge element 9.

The first portion 25 of the connecting rod is also provided with an end 29 located opposite the connecting rod region 27, in particular hinged to the outer surface 30 of the connecting plate 21a on the first living hinge element 5.

The second portion 26 of the link is also provided with an end 31 located in the opposite position to the link region 27, in particular hinged to the counter-bar means 10 so as to be able to rotate about the ninth rotation axis R9.

The first link portion 25 may comprise a "U" -shaped loop portion 32 and is arranged to at least partially surround the drive means 12 in order to reduce the footprint of the mobile device 1 in the closed configuration C.

The third lever means 6 may comprise a cross bar 6a, the end 33 of which is hinged to the first face 19a of the connecting block 15 of the second mobile hinging element 9, and the end 34, opposite to the end 33, is hinged to the first face 35 of the connecting block 14 of the first fixed hinging element 8.

In particular, the end 33 of the crossbar 6a is rotatably mounted between the connection block 15 and the connection plate 23a, and the other end 34 of the crossbar 6a is rotatably mounted between the connection block 14 and the connection plate 22 a.

The fourth lever means 7 may comprise an oblong element 7a, one end 36 of which is hinged to the outer surface 28 of the connecting plate 23a on the second movable hinging element 9, and the other end 37, opposite to the end 36, is hinged to the outer surface 38a of the connecting plate 22a on the first fixed hinging element 8.

The oval element 7a is generally shaped as a link or a crossbar.

The oblong element 7a may comprise a projection 39, facing the second lever means 4, on which the driving means 12 are mounted, for manoeuvring the mobile device 1 between the open configuration a and the closed configuration C.

The counter rod means 10 may comprise a counter rod 10a, one end 40 of which is hinged to the end 31 of the second portion 26 of the connecting rod on the profiled rod 4a, and the other end 41, opposite to the end 40, is hinged to the outer surface 42a of the connecting plate 24a on the second fixed hinge element 11.

The driving means 12 may comprise a pneumatic actuator 12a and an associated rotatable hollow body 43, in particular a sliding valve stem 44 connected to the outer surface of the connection plate 24a of the second fixed hinging element 11, and to the hollow body 43.

In the illustrated implementation, the head 45 of the stem 44 is connected to the oblong element 7a, in particular to the projection 39, moving the oblong element 7a; thus, movement of the mobile device 1 between the open configuration a and the closed configuration C is achieved due to the connection of the first lever means 3, the second lever means 4, the third lever means 6, the fourth lever means 7 with the trajectory modification assembly 20 and the hinge elements 5, 8, 9, 11. In other words, the pneumatic actuator 12a used pulls and/or pushes the oblong element 7a in an operating direction transversely spaced from the movement direction X, during which the inclination with respect to the movement direction X is variable, i.e. the first living hinge element 5 is moved in the movement direction X.

The mobile device 1 may be symmetrical about a substantially vertical symmetry plane S, as shown in fig. 4. In particular, the mobile device 1 may comprise components aligned with respect to a vertical symmetry plane S.
