Description

BACKGROUND OF THE INVENTION
The presente invention relates to a cross-lapping machine, which has been specifically designed for creasing, folding and cross-lapping, as well as collecting corrugated board materials.
The corrugated board material, in particular, is conveyed by conveyor belts, which are slidably supported on drive rollers and tension means.
The subject machine is very different from prior commercially available corrugated board folding machines.
The inventive machine, moreover, is adapted to perform not only creasing operations, but also folding, cross-lapping and collecting operations on the corrugated board material, the latter being conveyed into the subject cross-lapping machine as a continuous strip or web.
In this connection it should be pointed out that creasing, folding and cross-lapping operations are performed as a continuous process, to process comparatively high amount of corrugated board material, with a comparatively high yield much greater than that of prior batch operating cross-lapping machines.
A further advantage of the cross-lapping machine according to the present invention is that it is very simple construction-wise, and very competitive from a mere economic standpoint, the machine being moreover very safe and reliable in operation.
SUMMARY OF THE INVENTION
The above mentioned advantages, as well as yet other advantages, of functional and constructional nature, are achieved by the subject cross-lapping machine, specifically designed for creasing, folding, cross-lapping and collecting a corrugated board material, which is continuously fed, said cross-lapping machine being characterized in that it comprises a rotary member having, in an elevation view, a polygonal cross-section, preferably an octagonal cross-section, including, at the octagon apex points, a creasing contour, pressing the corrugated board material layers.
The mentioned creasing contour cooperates with a counter-roller, having a second creasing contour which is perfectly timed with respect to the first creasing contour, thereby the mentioned two creasing contours deform, at a cross direction and at opposite, but coinciding positions, the corrugated board material strip conveyed into the body of said cross-lapping machine.

    • DESCRIPTION OF THE PREFERRED EMBODIMENT
    With reference to the number reference of the figures of the accompanying drawings, the cross-lapping machine 6 according to the present invention is characterized in that it comprises an octagonal construction or structure 10', which can turn about a cross horizontal shaft 40.
    Said construction 10' is provided, as seen from a side, with a polygonal cross-section, preferably an octagonal cross-section, and comprises moreover, at the apex points of the octagon, creasing contours 32, provided for pressing the corrugated board material layers, in cooperation with a top counter-element 7 or 7''.
    The mentioned counter-element, or biassing-abutment element, comprises, as is shown in Figure 5, a top cylinder 7, covered by a layer of rubber or any other suitable resilient material, adapted to operate as a counter-biassing element for a creasing contour 32 applied at the apex points of said octagonal or polygonal grid construction 10'.
    The sides 10 of said grid construction are coupled and supported by diametrical arms 8, which extend spoke-like and are pivoted about the horizontal and cross shaft or axis 40.
    Alternatively, and as is shown in Figure 6, the creasing contours 32 are successively engaged at set positions coinciding with further contours 7'' applied to a cylinder 7'.
    The perimetrical extension of the cylinder 7 has been so designed as to correspond to the length of each side 10 of the octagonal construction 10'.
    The latter, in particular, is supported by a grid construction or structure 41, which supports, at a variable height, both the octagonal structure 10' and a top cradle 43, defined by the side walls 42, the bottom wall 14 and levelling side walls 22 and 27 which can perform a small reciprocating rectilinear movement.
    The mentioned top cradle 43 can be raised and lowered, since it is supported by the arms 44 in turn coupled to the supporting elements 45 and 46.
    The raising and lowering of said top cradle 43 is driven by hydraulic or pneumatic pistons 50, fixed, at an end thereof, to said structure 2 and pivoted, at their other ends, to the swinging arms 44.
    In this connection it should be pointed out that the octagonal structure or construction 10' comprises a vacuum pump, coupled to a rotary metering device 25, for metering air, coaxial with the rotary axis or shaft 40 of the octagonal structure 10'.
    At the other end of said rotary axis or shaft 40 a rotary metering device 24 and electrovalves coupled to an air compressor are arranged.
    The mentioned central rotary metering devices 24 and 25, through suitable ducts 33 and 34, as formed in and/or applied to the octagonal structure 10', are respectively coupled to suction suckers 30 and two blowing nozzles 31, which are suitably arranged on the arms 10 forming the above mentioned octagonal structure 10'.
    The suckers 30 and nozzles 31 provided respectively for holding the starting portions of the laps 3', 3'', 3''' and blowing on the opposite ends of said laps 3', 3'', 3''', allow to fold as a continuous strip the mentioned laps, as preliminarily creased.
    The mentioned corrugated board material laps or flaps 3', 3'', 3''' are collected on a supporting element 49 which is arranged, at the start, at a high position, thereby supporting, on its top rollers 18, the cross-lapped board material flaps.
    Said supporting and conveying device 49 is so designed as to assume variable heights, tending to reduce as the overlapped laps 3', 3'', 3''' are accumulated, said laps being folded by 180° onto one another, thereby providing a cross-lapping arrangement.
    As the lap stack 60 achieves a set height, a piston 15 is driven for operating a separating wall 14, to close the bottom of the mentioned cradle 43.
    Simultaneously with the closing operation, a cross movable blade transversely cuts the cross-lapped board laps or flaps 3' and 3'' at a folding line thereof.
    Upon cutting, the cross-lapped board material supporting device 49 is aligned, at the bottom, with a platform 35 including conveyor chains 37, pushing the bottom cross-lapped board material 60 in suitable directions A and B as shown in Figure 7.
    The conveyor chains, in particular, are driven by suitable motor-reducing units 54, 55, 56 and 57.
    Thus, the board laps or flaps 3 are collected on the cradle 43 which, as the stack height increases, tend to be lowered.
    The conveyor device 49, which is vertically movable, upon having unloaded the cross-lapped board stack 60, tend to rise and being arranged under the cradle 43 at a high position.
    As the conveyor device 49 arrives at its top dead point, the piston 15 will drive the separating wall 14 thereby opening the bottom of the cradle 43.
    In this operation, the cross-lapped board material portion collected on the bottom of the cradle, will be again arranged on the conveyor device 49, by falling on the rollers 18 of the platform 17.
    In this connection it should be pointed out that, during the creasing, folding and cross-lapping operations, a motor-reducing unit 19 will cause, through a rod-crank system 20 and 21, a levelling wall 22 to be displaced by a reciprocating type of movement.
    A further guide and holding wall 27 is moreover provided on a side of the cradle 43, for guiding and holding the creased, folded and cross-lapped board material.
    The cradle element 43, as stated, included a movable bottom wall 14, driven by a pneumatic cylinder 15.
    The stack 60 conveying and unloading device 49 comprises, in turn, a plurality of top rollers 18 which are supported by a perimetrical frame 17, in turn supported by swinging arms 16 pivoted to a bottom construction 48.
    The subject cross-lapping machine includes, according to a feature of the invention, a conveyor device including therein a plurality of conveyor chains 37 and motorized conveyor rollers.
    The octagonal construction 10' is rotatively driven by a motor-reducing unit or assembly 13, in turn rotatively driving a gear 12 meshing with a large diameter toothed wheel 11, coupled to said octagonal construction 10'.
    The toothed wheel 11, in turn, meshes with a further toothed wheel 61 engaging with a gear 62 rotatively driving yet another toothed wheel 63 coaxial with the creasing roller 7.
    It should be apparent that the cross-lapping machine according to the present invention has been disclosed and illustrated exclusively by way of an illustrative but not limitative example.
    Thus, while the inventive cross-lapping machine has been disclosed and illustrated with reference to a preferred embodiment thereof, it should be apparent that the disclosed embodiment is susceptible to several modifications and variations all of which will come within the scope of the invention as defined in the accompanying claims.
