    Detailed description of an embodiment example
    In the figures, reference numeral 50 generally designates a box stacking machine that includes a box size adaptation device according to an embodiment of the present invention. The box stacking machine 50 comprises a fixed frame 30 and an auxiliary frame 31 provided with wheels 32. An input conveyor 2 is provided on the auxiliary frame 31 provided with an endless belt that is moved in a forward direction D by a motor (not shown). In use, the input conveyor 2 is placed under a molding cavity of a box-forming machine (not shown), so that successive boxes formed by the forming machine are ejected from the molding cavity and fall on the conveyor of entry 2.
    The auxiliary frame 31 of the input conveyor 2 comprises lateral structures 18 on which input guides 1 are installed that direct the boxes moved by the input conveyor 2 towards a lifting cavity 4 located inside the fixed frame 30 a through an inlet opening 58 in the fixed frame 30. The inlet guides 1 have baffles 33 located in a region close to a distal end thereof. The lift cavity 4 is defined laterally by two movable side walls 3 parallel to the direction of advance D. Within the lift cavity 4 there is an end stop 7 which defines a box insertion limit for the box which is introduced into a direction parallel to the direction of advance D.
    A pair of lifting brackets 5 (better shown in Fig. 2) formed by respective horizontal bars adjacent to the two movable side walls 3 are installed in said lifting cavity 4. The two lifting brackets 5 have surfaces of support located in a horizontal plane. The lifting supports 5 are connected to a lifting carriage 34 which is moved vertically by actuators 6 along guides 42 fixed to the fixed frame 30 between a lower position, in which said lifting supports 5 are substantially flush with a transport surface 2a of the input conveyor 2 to receive one or more boxes from the input conveyor 2, and an upper position, in which the lifting supports 5 transfer the one or more boxes to a support device comprising a plurality of retractable nails 35 installed in the two movable side walls 3. Thus, the successive boxes are added from below to a stack of boxes that is supported by the retractable nails 35 of the support device.
    Above the level of the support device there is a pusher 36 fixed to an ejector carriage 37 that runs along a guide 38 parallel to the direction of travel D and which is moved horizontally by an actuator 39 to eject the stack of boxes from the delivery device. lift towards an exit path comprising exit guides 40 fixed to the movable side walls 3 and provided with support rollers 41. In positions adjacent to the entrance opening 58 there are retractable entry stops 59 (see the detailed detail of Fig. 1). Elastic elements 60 permanently push the input stops 59 towards a retention position above the level of the transport surface 2a of the input conveyor 2. The lifting supports 5, when moved to the lower position, push the stops of entry 59 towards a retracted position below the level of the transport sub-surface 2a of the input conveyor 2 against the force of the elastic elements 60.
    The case size adaptation device comprises first positioning means for regulating the position of the movable side walls 3 with respect to the fixed frame 30, second positioning means for regulating the position of the input guides 1 with respect to the auxiliary frame 31 of the input conveyor 2, and third positioning means for regulating the position of the end stop 7 with respect to the fixed frame 30 in order to adapt the box stacking machine to different box sizes.
    The first positioning means for regulating the position of the movable side walls 3 comprise a pair of horizontal guides 9 perpendicular to the direction of travel D fixed frame fixed 30 and located at a level lower than the transport surface 2a of the input conveyor 2. Each of the movable side walls 3 has fixed slides 11 (see also Fig. 3) slidably coupled to the corresponding horizontal guides 9 so that the movable side walls 3
    they can move along the horizontal guides 9 keeping their positions parallel to the direction of advance D.
    In a top part of the fixed frame 30 a first spindle 12 is rotatably installed perpendicular to the direction of advancement D, which has first and second threaded portions 12a, 12b with opposite thread directions. The movable side walls 3 have respective first and second nuts 13a, 13b attached to each of said first and second threaded portions 12a, 12b with opposite thread directions of the first spindle 12, so that a rotation of the spindle 12 causes about movements of the movable side walls 3 in opposite directions along the horizontal guides 9.
    The first spindle 12 has a first coupling 15 fixed at one of its ends located in an easily accessible position outside the fixed frame 30. This first coupling 15 is configured so that a first hand-operated crank 14 can be attached thereto. removable, so that by said first hand-operated crank 14 an operator can rotate the first spindle 12. The movable side walls 3 approach or separate from each other depending on the direction of rotation of the first spindle 12. The distance between the movable side walls 3 define the width of the lifting cavity 4 according to one of the dimensions of the boxes to be raised.
    One skilled in the art will understand that, alternatively, the first coupling 15 and the first removable hand-operated crank 14 can be replaced by a first hand-operated crank permanently coupled to the first spindle 12
    or by a motor group operatively connected to rotate the first spindle 12 without departing from the scope of the present invention.
    In a lower part of the fixed frame 30, another first first spindle 12 (Figs. 2, 5 and 6) is rotatably installed, which also has opposite first and second threaded threaded portions coupled to respective first and second nuts fixed to the movable side walls 3. Both first spindles 12 are mutually parallel and are connected to each other by a mechanical transmission composed of a roller chain 61 (Figs. 5 and 6) that cooperates with cogwheels, so that the first two spindles 12 they rotate simultaneously through the drive of the first hand-operated crank, or, where appropriate, the corresponding motor group.
    Preferably, the first and second threaded portions 12a, 12b with opposite thread directions of the first spindle 12 have a thread pitch small enough to make the coupling with the first and second nuts 13a, 13b irreversible, which constitutes a means of fixing to fix the movable side walls 3 in selected positions. However, the device may include alternative fixing means, for example by means of flanges or the like.
    As shown in Figs. 2 and 3, the lifting carriage 34 carrying the lifting supports 5 comprises a horizontal lower cross member 45 perpendicular to the forward direction D fixed at its ends to vertical members 46 connected to extendable rods of the respective actuators 6. The cross member bottom 45 has slides 47 coupled to the vertical guides 42 fixed to the fixed frame 30. Along the bottom crossbar 45 a horizontal guide 48 is fixed and each lifting support 5 is fixed to a secondary carriage 51 that has a slide 49 fixed slidably coupled to the horizontal guide 48 fixed to the lower cross member 45.
    Each of the movable side walls 3 has a vertical drag profile 62 fixed and each secondary carriage 51 has a drag follower 63 (Fig. 3) coupled to the corresponding vertical drag profile 62 so that it can slide vertically along the same. Thus, the vertical drag profiles 62 cooperate with the drag followers 63 to move the secondary carriages 51 and the lifting supports 5 fixed thereto in a horizontal direction perpendicular to the direction of travel D together with the moving side walls 3 and at the same time the movements guide the lifting supports 5 in the vertical direction.
    In an alternative embodiment (not shown), the vertical drag profiles 62 and the drag followers 63 are omitted, so that the secondary carriages 51 carrying the lifting supports 5 can be manually slid along the horizontal guide 48 of the lifting carriage 34 and the device includes fixing means, such as flanges or pressure screws (not shown) to fix the secondary carriages 51 with respect to the lower cross member 45 of the lifting carriage 34 in selected positions.
    The said second positioning means for regulating the position of the input guides 1 with respect to the side structures 18 of the auxiliary frame 31 of the input conveyor 2 comprise, for each input guide 1, a first joint 16 with respect to a vertical axis that connects rotatably a distal end or a region near a distal end of the inlet guide 1 to the corresponding side structure 18, and a linkage element 8 that mechanically links a proximal end of the inlet guide 1 to one of the movable side walls 3. Thus, the input guides 1 are moved
    automatically by the mobile side walls 3 when the mobile side walls 3 are moved by said actuation means.
    As the enlarged detail of Fig. 1 best shows, the linking elements 8 comprise a second joint 17 with respect to a vertical axis that rotatably connects the proximal end of each of said inlet guides 1 to an arm 43 fixed to a of the movable side walls 3. The first articulation 16 admits a movement in a horizontal direction of its corresponding vertical axis with respect to the corresponding entrance guide 1 or with respect to the corresponding lateral structure 18 of said auxiliary frame 31, for which the first articulation 16 includes a small connecting rod 44 articulated at its ends articulated to the inlet guide 1 and to the lateral structure 18.
    One skilled in the art will understand that, alternatively, it could be the second joint 17 that admits said movement in a horizontal direction instead of the first joint 16, and that in any case this movement in a horizontal direction could be provided by others alternative means, such as by means of the corresponding vertical axis of the joint slidingly inserted in an elongated hole formed in the inlet guide 10 in the lateral structure 18.
    The aforementioned third positioning means for regulating the position of the end stop 7 with respect to the fixed frame 30 comprise at least one horizontal guide 20 (better shown in Fig. 4) parallel to the direction of travel O fixed to a base 52 located at a level lower than the transport surface 2a of the input conveyor 2, which is in turn fixed to lower members of the fixed frame 30 that support the horizontal guides 9 that guide the movements of the moving side walls 3. The stop end 7 is installed on a movable support 22 that has a slide 21 fixedly slidably coupled to the horizontal guide 20. On the base 52 fixed to the fixed frame 30 a second spindle 23 parallel to said horizontal guide 20 is rotatably installed, and the movable support 22 has a third nut 24 attached to the second spindle 23. Thus, a rotation of the second spindle 23 causes movements of the stop 7 in a direction parallel to the direction of advance D.
    In the fixed frame 30, a drive shaft 25 is installed rotatably bearing a driving pulley 54, and the second spindle 23 has a driven pulley 55 fixed at one of its ends. A roller chain 56 is installed on the driving pulley. 54, the driven pulley 55, and several guide pulleys 57, so that a rotation of the drive shaft 25 drives the movements of the end stop 7. The guide pulleys 57 maintain
    the roller chain 56 in a position that does not interfere with the movements of the boxes that are introduced by the inlet conveyor 2 to the lifting cavity 4.
    The drive shaft 25 has a second coupling 26 fixed at one of its ends located in an easily accessible position outside the fixed frame 30, and this second coupling 26 is configured so that a second drive crank can be attached thereto. manual 27 removable, so that through this second hand-operated crank 27 an operator can rotate the second spindle 23.
    The end stop 7 approaches or moves away from the inlet opening 58 of the lift cavity 4 depending on the direction of rotation of the second spindle 23. The separation distance between the end stop 7 and the inlet opening 58 of the cavity Lift 4 defines the depth of the lift cavity 4 according to another of the dimensions of the boxes to be raised. Optionally, the end stop 7 can be positioned so that the lifting cavity 4 can accommodate two or more successive boxes at the same time.
    One skilled in the art will understand that, alternatively, the second coupling 26 and the second removable hand-operated crank 27 can be replaced by a second hand-operated crank permanently coupled to one end of the drive shaft 25 or by an operatively connected motor group to rotate drive shaft 25 without departing from the scope of the present invention.
    Preferably, the second spindle 23 has a thread pitch small enough to make the coupling with the third nut 24 irreversible. Alternatively, the second spindle and the third nut may be omitted and the third positioning means may include fixing means, such as one or more flanges or one
    or more pressure screws to fix the movable support 22 and the end stop 7 in a desired position along the horizontal guide 20.
    Fig. 5 shows box stacking machine 50 with the elements of the box size adaptation device of the present invention arranged in accordance with a maximum permissible box size. In such a case, the input guides 1 associated with the input conveyor 2 are arranged in a direction parallel to the forward direction D, the movable side walls 3 are aligned with the input guides 1, and the end stop 7 is in a position as far as possible from the inlet opening 58 of the lift cavity
    4. The lifting supports 5 are adjacent to the movable side walls 3.
    Fig. 6 shows box stacking machine 50 with the elements of the box size adaptation device of the present invention arranged in accordance with a relatively small box size. In this case, the inlet guides 1 are arranged in inclined directions with respect to the direction of advance O and convergent towards the inlet opening 58 of the lift cavity 4, the movable side walls 3 are aligned with the proximal ends of the inlet guides 1, and the end stop 7 is in a position relatively close to the inlet opening 58 of the lifting cavity
