    专利说明:

    [001] The present invention relates to a lifting conveyor belt with adjustable inclination.
    [002] More particularly, the present invention relates to a lifting conveyor belt in which it is possible to adjust the inclination or slope of one length or part of the belt with respect to another length or part.
    [003] As is known, conveyor belts are mechanical devices that have the function of moving, continuously or from one point to another, finished or semi-finished goods (arranged in bulk or in an orderly manner) along production lines, for example, to supply / load products on a production line, transfer them from one workstation to the next or to unload / store finished products.
    [004] Conveyor belts generally consist of a metal frame or structure comprising the belt support (the sliding surface of the support bearings), a drive pulley or bearing (usually the main pulley) and a guide pulley or bearing (usually the rear pulley) with inactive rotation and a belt made of canvas, impregnated canvas, rubber, rubberized canvas or a mesh made of plastic, steel or other known and suitable material on which semi-finished products or goods are positioned and transported, in a more or less orderly, during the production, storage or similar cycle.
    [005] Conveyor belts may have, according to specific requirements for the movement of products, with the type of product that will be moved or the layout of the system in which the conveyor belt is installed, a flat rectilinear development, may follow curvy paths or still have inclined development.
    [006] Particularly, the transmission belt with inclined or inclined development is used in the case of transporting material from a lower level to a higher level or vice versa.
    [007] A conveyor belt with such a structure may consist of a rigid and integrated structure comprising, for example, two horizontal portions arranged on different levels, rigid and stably connected to each other by means of an inclined intermediate portion with the inclination of the portion slope calculated in the design stage according to the requirements.
    [008] However, this solution has some problems related to the fact that it has to calculate precisely the inclination of the belt at the design stage and, in addition, it does not allow the reuse of the conveyor belt if different inclinations are necessary: in fact, this conveyor belt is tailored to a specific system.
    [009] According to other conventional embodiments, the structure of the inclined conveyor belt can be of the modular type with an inclined module disposed between belt modules positioned according to horizontal surfaces at different levels; for example, by varying the type of inclined intermediate module or by the level difference between the flat modules, it is possible to reconfigure the system.
    [0010] Although these solutions are convenient in relation to those with fixed inclination described previously, they still present some considerable problems related to the fact that each of the unique modules must be equipped with an adequate motor, with consequent complications regarding the control of the modules (in terms of conveyor belt speed) coupled in this way and the correct synchronization between them.
    [0011] To solve these problems, elevating conveyor belts were developed, in which the inclination of the intermediate portion for the two horizontal portions can be modified using lever mechanisms, rack and pinion type devices, return and inactive bearings for movement reciprocal sliding of the plates.
    [0012] A solution that solves the above problem is described, for example, in EP0731040, in which the conveyor belt comprises a support structure on which a sliding belt is wound, in which said structure comprises at least two articulated parts between itself for adjusting the reciprocal angular position of an inclined configuration (with an ascending or descending portion) for a configuration in which the aforementioned two portions rest on the same horizontal plane and in which, to maintain the tension of the conveyor belt constant when the configuration is changed, one of the portions of the structure comprises, with respect to the unrestricted ends, a flange that slides longitudinally within the suitable structure to change the longitudinal distance between the ends of the conveyor belt and optionally equipped with a pre-tensioned spring for elastic return .
    [0013] Another solution is described in document FR2956103, in which the adjustment of the angular position is implemented by means of a ramp equipped with bearings or similar sliding means and arranged correspondingly with the hinge connection between the portions of the structure, with one end articulated with respect to a part of the structure and with the other opposite end sliding in a groove of the adjacent portion of the structure, although the adjustment of the tension of the conveyor belt when the relative angular position between the mentioned portions is altered is obtained by means of guide bearings on which the conveyor belt is tensioned and which move in relation to the longitudinal direction of the advancement of the same belt.
    [0014] However, although these construction solutions efficiently solve the problem related to changing the inclination of the intermediate portion of the elevator and the movement control, they present some considerable problems related to the complexity of their construction (for example, large number of components) and project and, consequently, the resulting correlated costs.
    [0015] An additional disadvantage is linked to the fact that, in these conveyor belts with adjustable inclination, although they slide along parts with different inclinations, the belt tends to form "protrusions", that is, local deformations of the belt, which can prevent correct and uniform sliding of the belt and, consequently, the correct movement of the material on the same belt.
    [0016] The object of the present invention is to solve the problems indicated above.
    [0017] More specifically, the object of the present invention is the provision of an elevating conveyor belt with adjustable inclination, which is flexible and which easily adapts to different usage configurations.
    [0018] An additional object of the present invention is the provision of a lifting conveyor belt in which the adjustment of the inclination of a lift portion can be implemented simply and directly and without the formation of undesirable "protrusions".
    [0019] Another object of the present invention is the provision of a lifting conveyor belt that has simple construction and structure.
    [0020] An additional object of the present invention is to provide users with a conveyor belt with an adjustable tilt appropriate to ensure a high level of resistance and reliability over time and also in a way that it is produced easily and cheaply.
    [0021] These and other objects are achieved by the device according to the present invention which has the characteristics claimed in claim 1.
    [0022] According to the present invention, an elevating conveyor belt with adjustable inclination, suitable for moving finished or semi-finished products on different levels along production lines, is provided, comprising a support and rigidity structure divided into at least two adjacent sections defined by a horizontal section or loading section arranged according to a horizontal plane and by means of a lifting section arranged according to an inclined plane and a tensioned belt between an opposite front end of the horizontal section and a rear end of the lifting section and operated so that it slides by means of an electric motor, the horizontal or loading section and the lifting section are reciprocally articulated by means of an articulated connection comprising a mobile means suitable to ensure constant belt tension with the change in the reciprocal inclination between the mentioned sections.
    [0023] Convenient embodiments of the present invention will become apparent from the dependent claims.
    [0024] The functional and construction characteristics of the elevating conveyor belt with adjustable inclination in accordance with the present invention will be better understood from the detailed description below, in which reference is made to the attached figures, which represent one of his preferred achievements , but not limiting, in which: - Figure 1 schematically represents a side view of an elevating conveyor belt with adjustable inclination according to the present invention; Figure 2 schematically represents an axonometric view of the lifting conveyor belt according to the present invention; Figure 3 represents a schematic sectional view according to a vertical plane of the lifting conveyor belt of Figure 1; Figure 4 schematically represents a perspective view from below of the elevating conveyor belt according to the present invention, partially exploded to show the internal components; Figure 5 represents a schematic axonometric view partially exploded from above the conveyor belt; Figures 6 and 7 schematically represent two details enlarged, respectively, of Figure 5 (detail H) and Figure 4 (detail K); and - Figures 8A and 8B, 9A and 9B, 10A and 10B, 11A and 11B represent, according to a front and rear side view, different angular configurations of an inclination adjustment element of the conveyor belt according to the present invention. .
    [0025] With respect to the figures mentioned above, the elevating conveyor belt with adjustable inclination according to the present invention, indicated as a whole by 10, comprises a generally metallic structure defined by a structure 12 which, in the preferred embodiment according to the figures comprise at least two adjacent sections 14 and 16, reciprocally restricted by means of an articulated connection 13 according to the methods described below and arranged according to a horizontal plane (horizontal section 14 or loading section) and according to with a sloping plane (elevation section 16).
    [0026] The structure of the horizontal section 14 or loading section comprises two opposite edges 14 ', while the elevation section 16 comprises two opposite edges 16', with the mentioned opposite edges 14 'and 16' stiffened by means of transverse elements 21 .
    [0027] The structure 12 must be of appropriate size depending on the material (finished, semi-finished or similar products) moved and, consequently, the loads and static and dynamic stresses to which the conveyor belt is subjected during its operation.
    [0028] In addition, the aforementioned structure 12 is fixedly fixed to the floor by means of a fixed base and uprights, with optionally adjustable height or, as shown in the figures, by means of uprights 18 (with adjustable height) fixed to a base 20 movable by means of wheels 22 or equivalent means.
    [0029] The aforementioned frame has the function of maintaining and tightening the structure of the conveyor belt.
    [0030] With respect to the figures and considering the horizontal section 14 or loading section as the front element and the lifting section as the rear element, the frame 12 comprises a motor pulley 24 swiveled to the lifting section 26 corresponding to its rear end and a guide pulley 26 swiveled to the horizontal section 14 corresponding to its front end; wherein said motor pulley 24 and guide pulley 26 are disposed between the opposite edges 14 'and 16' of the two sections 14 and 16 and transversely thereto.
    [0031] The motor pulley 24 is rotated by means of an electric motor 25 (optionally equipped with a reduction unit), while the guide pulley 26 is an idle pulley, to determine the sliding movement of a belt 28 wrapped and tensioned on these pulleys.
    [0032] In addition, the frame 12 may comprise elements defined, for example, by idle rotational transverse bearings or by plate-like elements, positioned to support the sliding of the belt 28 to substantially define a suitable sliding surface to ensure improved stability products transported by the same belt.
    [0033] As introduced above, the horizontal section 14 or loading section and the lifting section 16 are reciprocally restricted by means of a hinged connection 13 comprising two opposite horizontal plates 30 fixed correspondingly to the rear end of the horizontal section 14 or section load and two opposite lifting plates 32 fixed correspondingly to the front end of the lifting section 16, with the mentioned opposite plates 30 and 32 fixed to the edges of the frames of the horizontal and lifting sections by means of retaining screw or similar type .
    [0034] The opposite horizontal plates 30 and the opposite lifting plates 32 are coupled together (with the opposite lifting plates 32 arranged internally to the opposite horizontal plates 30) correspondingly to the rear portions opposite to the fastening portions with respect to the opposite edges of the frame 12 of the two sections to define a fulcrum or joint comprising a coaxial pair of opposing bearings 31 (generally, though not exclusively, ball bearings) that support the idle rotation of a support bearing 34 arranged transversely in pairs opposites of plates 30 and 32; wherein said support bearing 34 is disposed less than belt 28 and, as defined above, produces a support for sliding said belt.
    [0035] The opposite plates 30 and 32 comprise grooves 36 with straight development that intersect each other appropriately to define the position of two opposite return bearings 38 facing inwards of the plates 30 and 32 towards the belt 28 and with the axis disposed parallel and above the axis of the support bearing 34; the return bearing 38 is in contact with the upper surface of the belt 28 and slides in an intermediate position between the mentioned return bearings 38 and the mentioned support bearing 34.
    [0036] The combined opposing horizontal plates 30 and the lifting plates 32 comprise additional grooves 40, with straight development, equipped with a graduated scale 42 (formed on the external face of the plates visible to the operator) for the function described in more detail below; transverse and internally to it, a containment element defined by a fixing screw 40 'is provided, which has the function of rigidly fixing the pairs of opposite plates and preventing relative rotation movements between them.
    [0037] The longitudinal development of the grooves 36 and the additional grooves 40 is calculated to allow changing the inclination of the lifting section 16 with respect to the horizontal section 14 or loading section in an angular range y (calculated with reference to a horizontal surface) generally from 15 ° to 60 °, as shown in Figures 8A to 11B.
    [0038] The method of adjusting the inclination of the conveyor belt described in detail above with respect to the construction characteristics is detailed below.
    [0039] If a change in the inclination of the elevation section 16 is necessary, the operator loosens the fixing screws 40 'and any stop elements 46 of the uprights 18 of the frame 12 that block the change in the height of the mentioned uprights 18 and, for in the middle of the graduated scale 42, they precisely adjust the inclination of the lifting section 16 with respect to the horizontal section 14 or the loading section to the desired angular value, with the return bearing 38 and the fixing screws 40 ', and slide with respect grooves 36 and additional grooves 40, as shown in Figures 8A to 11B.
    [0040] After reaching the required angular position, the fixing screw 40 'of the opposite plates 30 and 32 and the stop elements 46 of the uprights 18 of the frame 12 are fixed to prevent any relative rotation movements between the horizontal section or section load 14 and lifting section 16.
    [0041] Particularly, during the inclination adjustment step of the elevation section 16, the angular position of the return bearing 38 varies along a straight path (determined by the shape of the grooves 36) with an angular amplitude defined by an angle a, calculated with reference to the vertical drawn from the center of the bearing 31 and equal to the bisector of the angle y; in this way, it is possible to maintain the constant tension of the belt 28 by changing the inclination of the lifting section 16 with respect to the horizontal or loading section 14.
    [0042] As can be seen above, the advantages obtained by the conveyor belt according to the present invention are evident.
    [0043] Due to the articulated connection described, the elevating conveyor belt with adjustable inclination according to the present invention conveniently allows a quick, easy and precise change of the inclination of the conveyor belt, in order to adapt the conveyor belt to configurations of different layout.
    [0044] An additional advantage is represented by the fact that the opposing return bearings 38, by changing their position during the adjustment of the inclination of the lifting section along a straight line, ensure the constant tension of the belt 28, avoiding the formation of "protrusions", without the need to tighten or loosen them with an accessory means with the change of inclination.
    [0045] Another advantage is represented by the support bearing 34 which, arranged coaxially to the joint defined by the opposite plates 30 and 32, allows the number of components of the conveyor belt to be reduced and its construction to be simplified.
    [0046] An additional advantage is the fact that the conveyor belt according to the present invention has a modular structure that allows the expansion of the structure described with respect to the main realization shown in the figures by adding horizontal and / or tilting sections in series.
    [0047] Although not illustrated in the attached figures, on the belt 28, usually are provided, depending on the type of product transported, suitable transversal strips to support the production during the transfer.
    [0048] Although the present invention has been described above with particular regard to one of its realizations provided only by way of non-limiting examples, several modifications and variants of the above specification will be apparent to those skilled in the art. Therefore, the present invention is intended to include all modifications and variants that fall within the scope of the appended claims.
