Definitions

  • Said device has been developed around a single specific type of device Climb open with collapsible side panels and is therefore not suitable for climbing the same typology but with different ones constructive details and possibly different dimensions which, despite Compliance with the standard dimensions, just within the specified dimensional deviations are to unfold.
  • the invention therefore has as its object a method and a device for Unfold collapsible crates of the same type to create which but deviating dimensions just within the standardized dimensional deviations, Hinges between floor and side walls of different types and Arrangement, snap locks between the side walls different Type and arrangement, stiffening structures of the individual parts extremely of different types and geometries, and thus also during the automated opening bevel, can take different loads which results in different deformations.
  • the device according to the invention is advantageous device described in the aforementioned patent, on the loading side with Mechanism equipped with individual crates, from a stack of folded crates, while taking on the exit side Mechanism is provided which stacks the opened crates; like in The aforementioned patent also takes place in accordance with the subject method of Process according to a single direction of passage of the trays Unfolding in, to the loading and discharge level, raised position takes place.
  • the crate according to the invention on the mechanism of vertical conveyance by means of four Pairs of roles recorded with at least one role per pair with one Toothing is provided.
  • the rollers are on a rocker arm with a vertical Swivel axis mounted, which in turn with a swivel arm vertical axis of rotation is mounted laterally on the support structure for the crate and is pulled against the side edge area of the tray bottom.
  • the invention proposes to provide rolling elements on the gripping members of these swivel arms which secure the gripping capacity while opening but at the same time compensating sliding and, during the lowering movement of the opened crates, sliding without damaging the Enable crate surfaces.
  • the invention proposes in the gripping area of the swivel arm a series of rollers with an external thread or protruding rings, or a series of disks which are mounted on several parallel axes lying transversely to the swivel radius of the swivel arm and in the same plane and in the circumferential region have a triangular cross section
  • the problems of gripping the swivel arms on the transverse side walls, which are opened after the longitudinal side walls, are solved in accordance with the invention in that the tray base is easily raised by means of pneumatically liftable supports such that a pressure against the swivel arm on the transverse side wall the tray bottom is exercised, causing it to bend downwards and so, be it the insertion of the gripping tooth between the tray bottom and the non-bent transverse side wall, as well as the attachment of the gripping members at the upper edge of the side walls, which, with regard to the different tray manufacturers, have different strengths, structures and Can have hinge linkage to allow.
  • the gripping end of the swivel arm is according to the invention, for the purpose of opening the Transverse sidewalls, provided with a flange which in the middle area has a wedge-shaped tooth which is located during the gripping process upper edge of the transverse side wall in the space which by the Bending of the bottom of the crate due to lifting by the pneumatic operated conditions in the area of the four riser corners, with the Back surface directed against the bottom of the tray, pushes in.
  • the tooth under the edge of the transverse side wall has two effects Pads which are in the gripping area, laterally shifted in relation to the wedge-shaped tooth are arranged and on the opposite surface of the act on the same wall.
  • the invention proposes a second use of the pneumatic from below in the four corner areas on Steigenboden in front of existing supports by lifting this floor slightly to prevent that, while lowering the crates into the feed and Outlet level and especially while pulling out the unfolded Get out of the gripping organs which stress and deform the Rising parts cause the undesired loosening of one of the snap connections which could be caused by mutual displacement under load, by the cushions which are prevented from below in the corner areas of the Rise work.
  • This process is also particularly effective, be it on climbs less stable and easily deformable structure as well as on crates with stiffer Divide those in the lowering phase of the crate by pulling out the side walls the gripping organs, require greater forces and thus tend to have greater forces To cause loads at the joints between the side walls.
  • the folded crate 8 during its feeding 8a and during the changeover from the Guides 1 on the guides 3 of the lifting mechanism, from four pairs of rollers 4h, 4i retained which are articulated on spring-loaded rocker arms are.
  • the rollers act laterally on the two surfaces of the longitudinal edge of the floor where the different crates stiffening structures of different types and very of different dimensions, which are essentially vertical arranged ribs 8x and flat surfaces 8y are marked which in the same level with the backs of the ribs and with the outermost circumferential edge 8z of the lower support surface of the tray bottom, Layer.
  • At least one of the rollers 3h, 3i is each Pair with teeth so that the ribs 8x in the gaps between the Teeth can protrude and so the lower side surfaces of the teeth during the Sequence of all movements of the lifting mechanism 8c on the tray with the floor restrain the structure of the lifting mechanism.
  • the tray 8 to be subsequently opened is vertically into the opening station raised 8c where in a first moment the opening of the long side walls 8k by means of swivel arm 7a.
  • This is coaxial with its swivel axis to a hypotetic swivel axis which is made up of, out of different hinge axis positions between the long side wall 8k and floor 8d of the different crate models, Average position results.
  • the arm 7a has two gripping elements 7b laterally on the opposite edges of the same longitudinal side wall 8k Act.
  • both gripping elements 7b are with rollers 7f with an external thread which are rotatable, parallel to each other and at right angles to the Swivel radius arranged axes, are stored.
  • the rollers 7b allow during the unfolding movement of the side wall 8k, the compensation sliding which is required when the swivel arm 7, with respect to the hinge axis of the Sidewalls 8k, not coaxial to the pivot axis of the arm Damage to the hinges between side wall 8k and floor 8d too avoid.
  • Swing frame 6c for opening the transverse side walls 8b in operation are pivotable with a hypotetically arranged axis of rotation 6 stored which is from the mean of the hinge axis positions between Cross side wall 8b and bottom 8d of the different from the device hinged trays 8 results.
  • the frames 6c have one at the end Angular arm 6a the adjustable 6j gripping element 6b.
  • the arm 6a can different heights of the side walls 8b of the trays 8 are adapted and is driven by pneumatic cylinders 6e 6g around the top of the To take transverse side wall 8b.
  • the bottom 8d of the crates in the four corners corresponding areas by movable supports 9 which on the support 3rd of the lifting mechanism are provided, raised 9a.
  • Lifting 9a causes the gripping element 6b the tray bottom with the centrally arranged wedge-shaped tooth bends down 6h and then this in the resulting gap between bottom 8d and side wall 8b introduces 6g.
  • the side wall 8b progressively through introduction surfaces which on two, are provided on the gripping element 6b attached angle 6i, bent.
  • the support members 9 which function in the corner areas on the bottom of the crate by this slightly raises 9a and thereby causes that subsequently, during the Lowering 3e of the crate 8 which by the rollers 3h, 3i on the support 3 of the Lifting mechanism is held and thus during the loads by pulling the riser parts out of the gripping elements for the Unfolding and snapping the sidewalls occur, the snap organs which don't seem to let go between the side walls.
  • the support guides 3 are for the crate 8 again with the guides 4 for the exit from the opening station B. and with those 4a of the subsequent stacking station for the opened crates aligned.
  • the movement of the crates 8 takes place along these guides by means of pneumatic cylinder 5c which actuates a pivotable driver 5a.
