    End stop device for box stacking machine. The end stop device comprises an end stop (7) disposed in a lifting cavity (4) of a box stacking machine where there is a lifting support (5) that is moved vertically by at least one actuator (6) between a lower position, wherein said lifting support (5) receives one or more boxes from an input conveyor (2), and an upper position, in which the lifting support (5) transfers the one or more boxes to a lift device. The position of the end stop (7) is adjustable with respect to a fixed frame (30) of the machine in a forward direction (d) of the input conveyor (2), and the position of the end stop (7) determines that the cavity lift (4) can accommodate one or more boxes at a time, and/or adapts the lifting cavity (4) to different box sizes.

    Lower level of the stack, or what is the same, is capable of simultaneously supporting several stacks of adjacent boxes.
    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 input 59 towards a retracted position below the level of the transport surface 2a of the input conveyor 2 against the force of the elastic elements 60.
    In order to adapt the box stacking machine 50 to different box sizes, the box stacking machine 50 comprises first positioning means for regulating the position of the end stop 7 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 movable side walls 3 with respect to the fixed frame 30.
    The first 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 D 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 movable side walls 3. The end stop 7 it is installed on a mobile 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 spindle 23 is rotatably installed parallel to said horizontal guide 20, and the mobile support 22 has fixed a nut 24 coupled to the spindle 23. Thus, a rotation of the spindle 23 causes movements of the stop 7 in a direction parallel to the forward direction D. Preferably Then, the spindle 23 has a thread pitch small enough to make the coupling with the nut 24 irreversible.

    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 they guide the movements of 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 automatically moved by the moving side walls 3 when the moving 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 1 or in the lateral structure 18.
    Fig. 5 shows a box stacking machine 50 with several elements 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 lift brackets 5 are adjacent to the movable side walls 3.
    Fig. 6 shows a box stacking machine 50 with the elements arranged according to a relatively small box size. In this case, the inlet guides 1 are arranged in inclined directions with respect to the direction of advance D 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 lift cavity 4. The lift supports 5 are adjacent to the movable side walls 3.
    The scope of the present invention is defined in the appended claims.
