    [0003] OCTOGONAL PRISMAT CORRUGATED HOLLOW GIVEN WITH EIGHT FACES
    [0004]
    [0005] SECTOR OF THE TECHNIQUE
    [0006]
    [0007] The present invention concerns with an apparatus for vertically raising a hollow octagonal prismatic corrugated cardboard drum, provided with eight thin and smooth side faces. The term "smooth faces" refers to the fact that said drum to be loaded has no profiles, projections, flanges, perforations or holes to allow it to be lifted. Thus, the lifting is carried out by friction. Said corrugated cardboard comprises at least one sheet of paper plain and a sheet of corrugated paper, adhered to each other.This type of corrugated cardboard is known as single-sided, so the double-sided corrugated cardboard, provided with two outer smooth sheets of paper between which is inserted at least one sheet of corrugated paper, triple-sided corrugated cardboard, etc.
    [0008]
    [0009] BACKGROUND OF THE INVENTION
    [0010]
    [0011] The apparatus of the present invention is useful for lifting the drums described in documents ES2666269A1, P201731463, U201830796, U201830798, U201830802, and U201830797. Said drum is made of prismatic, octagonal and hollow corrugated cardboard. Said drum is provided with a body of eight thin and smooth faces separated by folds parallel to the vertical direction. The drum is closed in its lower part with a base attached to the extrados of the body, and is open in its upper part. Said eight faces define an intrados and an extrados of said drum.
    [0012]
    [0013] Document US2327005A shows an apparatus for raising a metal cylindrical barrel with a cylindrical crown free of flanges at its end. Said apparatus is apt to load the barrel vertically by friction. The apparatus comprises a suffering structure with a horizontal tube and a vertical tube welded in an inverted T-shape with two round curved interiors fixed at both ends of the horizontal tube. The apparatus comprises a movable support with respect to the suffering structure. Said movable support comprises a shirt-type support slidably mounted with respect to said vertical tube of the suffering structure and two members of pressure materialized in respective arms equipped with a curved outer round. The shirt support is provided with a coupling for coupling said device to a lifting device, for example, forklift, hoist, etc. These two arms are diametrically opposite and are pivotally mounted on the sleeve support and on the respective ends of the horizontal tube. When the apparatus is lifted by pulling the coupling, the shirt support rises, the arms swing, the inner rounds of the suffering structure press on the inner wall of the barrel cylindrical crown and the outer rounds press against the outer wall of the cylindrical crown of the barrel. barrel, thus raising the load. The apparatus lifts the barrel by pressing two opposite curved portions of the barrel by friction due to the flat geometry of the apparatus.
    [0014]
    [0015] Document US20010001525A1 shows an apparatus for lifting a cylindrical container of thin-walled wooden conglomerate, that is, the container has no ridges to allow its lifting. The apparatus comprises a flat suffering structure that has a curved wall fixed at each of its two ends. The two curved walls are attached to the outside of the tubular wall. The apparatus comprises a movable support with respect to the suffering wall. When lifting the load, the mobile support is raised by pivoting two curved pressure members that trap the inner wall of the cylinder against the curved walls of the suffering structure, which press the outside of the cylinder. Mobile support and sufridera wall are locked with the pressure members in the open position by a pin inserted in a hole.
    [0016]
    [0017] A drawback of document US20010001525A1 is that the suffering structure is on the outside and the pressure members curved on the inside. This, together with the need to increase the number of pressure points, causes reduced visibility during the operation of placing the apparatus on the top of the drum and checking the closure of the pressure members.
    [0018]
    [0019] A problem with the devices of US2327005A and US20010001525A1 is that they press the load walls only at two diametrically opposite points. Since the container to be raised is metallic and a conglomerate of wood, respectively, this may be sufficient in these applications. However, a number of pressure points greater than two and a greater friction surface are needed to lift the corrugated cardboard drum full of product without breaking, crushing or crushing the corrugated paper sheet or sheets that are an integral part of the Corrugated cardboard without deforming the top of the drum or its side faces. If a sheet of corrugated paper breaks, crushes or chafa destroying its wavy shape, the expansion and compression resistance of the corrugated cardboard drum decreases dramatically. For example, the drums will resist a lower weight when a drum is stacked on top of the other, after being manipulated with the apparatus to load the drum vertically. Likewise, the upper open part and the sides of the drum must not be subject to deformations due to the use of the apparatus on the corrugated cardboard drum so as not to reduce the resistance of the drum for later use.
    [0020]
    [0021] Document DE3314806C1 shows an apparatus with eight pressure points. Said apparatus does not exhibit a suffering wall, since the apparatus is suitable for feeding cylindrical articles pressed into round storage containers. It includes a support where a motor connected to a ball screw is mounted. With the rotation of the motor, the ball screw drives eight arms, which extend radially from the center of the support. However, a hollow octagonal prismatic corrugated cardboard drum with thin faces cannot be lifted by this device, since it does not have an internal suffering structure that counteracts the pressure of the eight arms, thus allowing its lifting by friction, avoiding deformation of the faces and the damage by crushing and / or crushing the corrugated corrugated cardboard.
    [0022]
    [0023] Document FR2939452A shows a clamp for lifting plates with four pressure points and a suffering structure with a cylindrical wall of reduced surface area. Said four pressure points correspond to four pressure members that are moved by a cylinder supported in the cylindrical bearing structure against the outside of the plate to be raised. The suffering structure is fixedly connected to the lifting support, which includes a coupling for connection to a lifting device, for example, a forklift. The cylindrical wall is inserted into the center of the plate to be raised to reduce the deformation of the plate due to the pressure of the four thrust members. These four pressure members have pointed protrusions that are embedded in the cover plate for lifting. Such pointed protrusions would break the wave of corrugated cardboard and decrease the mechanical strength of the corrugated cardboard drum. In addition, the apparatus is configured and is suitable for lifting essentially flat objects, specifically plates. In addition, the cylindrical suffering structure is not even adapted for lifting thin-walled cylindrical objects.
    [0024] Document US3264027A shows a tool with four hooks facing two to two and distributed around the outer side of a cylindrical wall. The tool manually lifts a substantially cylindrical, hollow, and thin-walled container with ridges. The tool comprises a support with a movable part that, when manually pressed by an operator, moves hooks against a circular flange located in the upper part of a cylindrical wall. In the locked position, the hooks press the edge of the container against the circular flange of the cylindrical wall.
    [0025]
    [0026] A drawback of this tool is that it needs said container flange and said circular flange for lifting the load. The hooks are pusher members that do not press the wall of the cylindrical container on the cylindrical wall, but rather the hooks press the flange of the container against the circular flange. Therefore, the cylindrical wall does not suffer pressure and is not a suffering wall, and the tool is not suitable for lifting a hollow cylindrical container provided with eight smooth faces, that is, free of profiles, perforations, flanges or flanges to allow its hoisting
    [0027]
    [0028] None of the above documents provides an apparatus for vertically raising an octagonal prismatic corrugated cardboard drum provided with eight thin and smooth faces, without breaking, crushing or crushing the corrugated paper sheet or sheets that form an integral part of the corrugated cardboard, without deforming the upper part of the drum or its side faces, and improving visibility during the operation of placing the apparatus on the upper part of the drum and checking the closure of the thrust members.
    [0029]
    [0030] EXPLANATION OF THE INVENTION
    [0031]
    [0032] The present invention contributes to solve the above and other inconveniences, providing an apparatus for raising, according to a vertical direction, an octagonal and hollow prismatic corrugated cardboard drum. Said drum is provided with a body of eight thin and smooth faces separated by folds parallel to the vertical direction. The drum is closed at the bottom with a base, and open at the top. Said eight faces of the drum define an intrados and an extrados of said drum.
    [0033]
    [0034] Each face of said body may include one or more layers of corrugated cardboard, which causes its thickness to vary. Said corrugated cardboard comprises at least one sheet of plain paper and a sheet of corrugated paper, attached to each other. This type of corrugated cardboard is known as simple face. Thus, double-sided corrugated cardboard is provided within the scope of the present invention, provided with two sheets of plain paper between which at least one sheet of corrugated paper is sandwiched, triple-sided corrugated cardboard, etc.
    [0035]
    [0036] Said apparatus comprises in use a support provided with a coupling attachable to a lifting device. Examples of said lifting device can be a forklift, hoist, bridge crane, among others.
    [0037]
    [0038] Likewise, the apparatus includes four first pressure members facing two to two, connected to said support, and which are movable between an open position in which they do not exert pressure against a suffering structure and a closed position in which they exert pressure on a suffering structure.
    [0039]
    [0040] Also, the apparatus comprises a suffering structure operatively connected to the support or which is an integral part of the support against which the first four pressure members press in use in the closed position.
    [0041]
    [0042] Likewise, said suffering structure comprises four first lateral suffering walls that provide respective essentially flat pressure surfaces, essentially parallel to said vertical direction of elevation, and facing two to two.
    [0043]
    [0044] Said first four lateral suffering walls define an octagonal contour of eight sides suitable for introduction by the top of the drum. Said octagonal contour is configured so that, in use, each first side wall is facing and attached with a respective alternate face of the drum intrados.
    [0045] Each pair of first essentially flat lateral walls are separated by distances greater than the length of the other pair of first lateral walls, whereby the lateral ends of each first lateral wall define an octagonal contour.
    [0046]
    [0047] In said apparatus, each first movable pressure member is disposed on the outside of its respective first side wall of the wall structure.
    [0048] In addition, in the apparatus, each first pressure member presses in use in the closed position a respective alternate face of the drum extractors against a respective first side wall.
    [0049] Also, in said apparatus the distance between the pressure surface of each first pressure member in its closed position and its respective first alternating side wall is between 3 and 50 mm.
    [0050]
    [0051] Thus, the present invention provides an apparatus for vertically raising an octagonal prismatic corrugated cardboard drum provided with eight thin and smooth faces, without breaking, crushing or crushing the corrugated paper sheet or sheets that form an integral part of the corrugated cardboard, without deforming the upper part of the drum or its side faces, and improving visibility during the operation of placing the apparatus on the upper part of the drum and checking the closure of the thrust members.
    [0052]
    [0053] Thus, with said apparatus with at least four pressure points, by means of said four pressure members, and a greater greater friction surface by means of the first suffering side walls, the corrugated cardboard drum filled with product rises without breaking, crushing or crushing. the sheet or sheets of corrugated paper that are an integral part of the corrugated cardboard and without deforming the top of the drum or its side faces.
    [0054]
    [0055] Also, the quality of the corrugated cardboard can be diminished, and therefore, the manufacturing cost of the drum can decrease without the sheets of corrugated paper being crushed or broken when the drum is handled with said lifting device.
    [0056]
    [0057] Preferably, said suffering structure further comprises four second lateral suffering walls, which provide respective essentially flat pressure surfaces, essentially parallel to said vertical direction of elevation, and facing two to two.
    [0058]
    [0059] Said four second lateral side walls, together with the first four side walls, define said octagonal contour of eight sides. The first four and four second side walls are arranged in alternate edges of the octagonal contour. Said octagonal contour is suitable for introduction by the top of the drum. Likewise, said octagonal contour is configured so that, in use, each of the eight lateral suffering walls is arranged facing and attached to each of the eight faces of the drum intrados.
    [0060] Also preferably, the apparatus further comprises four second pressure members arranged on the outside of the suffering structure, and connected to said support.
    [0061] Said four second pressure members are movable between an open position in which they do not exert pressure on the suffering structure and a closed position in which they exert pressure on the suffering structure.
    [0062]
    [0063] Each second movable pressure member is disposed on the outside of its respective second side wall of the wall structure.
    [0064]
    [0065] Likewise, each second pressure member presses in use in the closed position a respective alternate face of the extrados of the drum against a respective second side wall.
    [0066]
    [0067] With this, the eight faces of the drum are subject to friction in use by the pressure of the first four pressure members against their respective first lateral suffering walls and the pressure of the four second pressure members against the respective four second lateral suffering walls.
    [0068]
    [0069] Thus, with said apparatus with eight pressure points, by means of said first four pressure members and said four second pressure members, and a greater friction surface by means of the first and second suffering side walls, the corrugated cardboard drum filled with product is without breaking, crushing or crushing the corrugated paper or sheets that form an integral part of the corrugated cardboard and without deforming the top of the drum or its side faces.
    [0070]
    [0071] Also, the quality of the corrugated cardboard can be further reduced, and therefore, the manufacturing cost of the drum can be further reduced without the corrugated paper sheets being crushed or broken when the drum is handled with said lifting device.
    [0072]
    [0073] The distance between each second pressure member in its closed position and its respective second side wall is between 3 and 50 mm.
    [0074]
    [0075] Optionally, in the apparatus, said support and said suffering structure are slidably connected. Thus, said support is movable between a lower position, where the first and / or second pressure members are in said open position; and a lifting position, wherein the first and / or second pressure members are in said closed position.
    [0076]
    [0077] Optionally, the apparatus further comprises a locking and unlocking device supported on the support. The locking and unlocking device blocks the support with respect to the blocking structure and the first and / or second pressure members in the closed position, when the coupling is pulled in the vertical direction upward to raise the drum. The locking and unlocking device maintains the blocking of the first and / or second pressure members during lifting and after lowering the drum.
    [0078]
    [0079] In another option, the apparatus further comprises a second locking and unlocking device supported on the support. The second locking and unlocking device blocks the support with respect to the suffering structure and blocks the first and / or second pressure members in the open position, when the coupling is pulled in the vertical direction upwards to raise the drum.
    [0080]
    [0081] Optionally, each first and / or second pressure member is provided with an essentially flat pressure surface. According to one option, each of first and / or second essentially flat pressure members may be provided with an essentially rectangular pressure surface with two second lateral edges coinciding with two respective contiguous folds of the eight faces of the drum.
    [0082]
    [0083] Optionally, each of the first four and / or four second essentially flat side wall walls are provided with a respective essentially rectangular pressure surface with two side edges parallel to the vertical direction and essentially coinciding with two respective contiguous folds of the eight faces of the drum. Thus, at least one said edge coincides with each of the eight folds of the drum body. This helps to mitigate the deformation of the top of the drum.
    [0084]
    [0085] Also in a complementary manner, the apparatus comprises four or eight arms mounted radially on an XY plane of the suffering structure perpendicular to the vertical direction. Also, each of said arms is provided with a respective proximal end and a respective distal end, and pivotally connected to the suffering structure by a respective first axis.
    [0086]
    [0087] Likewise, each of the arms is connected by its proximal end pivotally to the support by means of a respective second axis. In addition, each distal end of the arms is fixed to a respective first or second pressure member.
    [0088]
    [0089] Thus, said arms can pivot about the first axis between the open position when the support is in its lower position, and the closed position when the support is in its upper position. Said support is movable between said positions thanks to the sliding connection of the support with respect to the suffering structure.
    [0090] Optionally, in the apparatus, each arm further comprises a link provided with a lower end and an upper end. Said lower end is pivotally connected to the proximal end of the arm by said second axis. Said upper end is pivotally connected to the third axis. Each arm also comprises a third axis that pivotally connects the upper end of the link with the support.
    [0091]
    [0092] In addition, the apparatus further comprises two projections, associated with two respective first opposite side walls. Each of the projections is provided with respective support surface in an XY plane perpendicular to the vertical direction that supports in use against the edge of the opening and / or mouth of the top of the drum.
    [0093]
    [0094] The terms "corrugated cardboard" and "corrugated cardboard" are synonyms. The term "thin faces" includes faces whose thickness is between 3 and 50 mm.

    [0126] DETAILED EXHIBITION OF EMBODIMENTS / EXAMPLES
    [0127]
    [0128] According to a first aspect of the present invention, Figs. 1, 2, 3, 5 and 6 show a first embodiment of the apparatus (50) for raising, according to a vertical direction (Z), a drum (80) of octagonal and hollow prismatic corrugated cardboard.
    [0129]
    [0130] An example of said drum (80) is shown in detail in Figs. 13 to 15. Said drum (80) is provided with a body (85) of eight thin and smooth faces (81) separated by folds (82) parallel to the vertical direction (Z). The drum (80) is closed at its bottom with a base (83). The drum (80) is open at its top. Said eight faces (81) of the drum (80) define an intrados and an extrados of said drum (80).
    [0131] In Fig. 14 the layers (86) of the body (85) that make up said drum (80) are shown in detail. In Figs. 13 and 14 the body (85) comprises two layers (86). Each of the layers (86) of the example may represent a triple-sided corrugated cardboard. The triple-sided corrugated cardboard comprises three smooth sheets (87), two outer and one inner, between which two corrugated sheets (88) are interspersed alternately. In the Fig. 14 shows that one wave of a wavy sheet (88) is smaller and the other wave of the other wavy sheet (88) is larger.
    [0132]
    [0133] Going back to Figs. 1 and 2, the apparatus (50) comprises a support (1) with a coupling (2) fixedly connected in use to the support (1). The coupling (2) is attachable to a lifting device (not shown).
    [0134]
    [0135] In Figs. 1 to 3 it is shown that the apparatus (50) includes four first pressure members (41) facing two to two and connected to said support (1). The first four pressure members (41) are movable between an open position (Fig. 5) in which they do not exert pressure against a suffering structure (6) and a closed position (Fig. 6) in which they use pressure on a sufridera structure (6).
    [0136]
    [0137] Following in Figs. 1 to 3, the apparatus (50) comprises a suffering structure (6) operatively connected to the support (1) against which the four pressure members (41) press in use in the closed position (Fig. 6). The sufridera structure (6) is slidably connected through its tube (16) to the support (1).
    [0138]
    [0139] Said sufferer structure (6) shown in Figs. 1, 2 and 3 comprises four first lateral suffering walls (51) that provide respective essentially flat pressure surfaces, essentially parallel to said vertical direction (Z) of elevation, and facing two to two (Fig. 3).
    [0140]
    [0141] Figs. 1, 2 and 3 show that said four lateral suffering walls (51) define an octagonal contour (C) of eight sides suitable for introduction by the top of the drum (80). In Fig. 3 the octagonal contour (C) is shown in dashed line and dot. In Figs. 5 and 6 shows said apparatus (50) introduced by the top of the drum (80). Said octagonal contour (C) is configured so that, in use, each first lateral bearing wall (51) is facing and attached with a respective alternate face (81) of the drum intrados (80), as shown in Figs. 5 and 6
    [0142]
    [0143] In Figs. 1 to 3, each pair of first lateral suffering walls (51) facing each other is separated by distances greater than the length of the other pair of first lateral suffering walls (51) facing each other, bringing the lateral ends of each wall lateral bearing (51) defines an octagonal contour (C) as can be seen in detail in Fig. 3. In Fig. 3, the first lateral bearing walls (51) aligned according to the X direction are separated a distance greater than the along the first lateral side walls (51) aligned according to the Y direction. Similarly, in Fig. 3 the first walls side rails (51) aligned according to the Y direction are separated a distance greater than the length of the first side rails walls (51) aligned according to the X direction
    [0144]
    [0145] Figs. 1, 2, 3, 5 and 6 show that in said apparatus (50) each first movable pressure member (41) is disposed on the outside of its respective first side wall (51) of the wall structure (6).
    [0146]
    [0147] Fig. 5 shows that, in the apparatus (50), each first pressure member (41) presses in use in the closed position a respective alternating face (81) of the extrados of the drum (80) against a respective first lateral suffering wall (51).
    [0148]
    [0149] Figs. 1 to 3 show that in said apparatus (50) the distance (D1) between the pressure surface of each first pressure member (41) in its closed position and its respective first alternating lateral bearing wall (51) is between 3 and 50 mm Said distance (D1) is associated with the thickness of the layers (86) of the body (85) of the drum (80).
    [0150]
    [0151] According to a second embodiment of the apparatus (50) of the present invention, Figs. 7 and 8 show that the apparatus (50) comprises the characteristics and elements of the first embodiment and in addition the suffering structure (6) comprises four second lateral suffering walls (52). Said four second side bearing walls (52) provide respective essentially flat pressure surfaces, essentially parallel to said vertical direction (Z) of elevation, and facing two to two.
    [0152]
    [0153] In Figs. 7 and 8, the four second lateral suffering walls (52), together with the first four lateral walls (51), define said octagonal contour (C) of eight sides. The first four and four second lateral suffering walls (51, 52) are arranged in alternate edges of the octagonal contour (C). Said octagonal contour (C) is suitable for introduction by the top of the drum (80).
    [0154]
    [0155] Likewise, in use, each of the eight lateral suffering walls (51, 52) is arranged facing and attached to each of the eight faces (81) of the drum intrados (80). Fig. 15 shows this situation for the third embodiment, which will be explained later.
    [0156]
    [0157] According to a third embodiment of the apparatus (50) of the present invention, Figs. 4, 15 and 9 to 12 show that the apparatus (50) comprises the elements and characteristics of the second embodiment and also four second pressure members (42). Sayings four second pressure members (42) are arranged on the outside of the suffering structure (6) and connected to said support (1).
    [0158]
    [0159] Furthermore, said four second pressure members (42) are movable between an open position in which they do not exert pressure on the suffering structure (6) and a closed position in which they use pressure on the suffering structure (6).
    [0160] In Figs. 9 and 10 it can be seen that each second movable pressure member (42) is disposed on the outside of its respective first side wall (52) of the wall structure (6).
    [0161]
    [0162] Likewise, in Fig. 15 it is shown that each second pressure member (42) presses in use in the closed position a respective alternate face (81) of the extrados of the drum (80) against a respective second lateral suffering wall (52) .
    [0163]
