Definitions

  • the invention relates to a covering device for goods stored in particular in cold stores or storage rooms according to the preamble of claim 1.
  • Covering devices of this type are used, for example, to be able to subject fruit products, such as bananas, which are stored in refrigerated or storage rooms, usually packaged in cartons or boxes, to effective cooling and / or ventilation, which is of great importance for the ripening and quality-preserving storage of the fruit products.
  • the cover unit also called the cover panel, which has been lowered from the ceiling of the refrigerator or storage room after the fruit products have been introduced, together with the air guide elements arranged above the cover unit, mean that the air cooled or circulated by air coolers or fans on the ceiling must flow through the goods underneath and not above the goods can circulate ineffectively.
  • the invention has for its object to provide a cover device of the type mentioned, in which the raising and lowering of the cover unit can be done in a simple, smooth, low-wear, maintenance-friendly and absolutely uniform manner.
  • a plurality of flexible suspension elements for example suspension ropes
  • a common pull rod which are acted upon simultaneously and evenly in the lifting or lowering direction when the pull rods are displaced.
  • This causes a corresponding Even, horizontal lifting and lowering of the cover unit.
  • the tie rods have no elongation at all and the suspension ropes can be of the same and a minimal length.
  • the elongation of these suspension ropes will therefore be relatively low even after a long period of use and is completely harmless since, provided the suspension ropes are subjected to the same load, the elongation amounts are the same.
  • the use of the pull rod according to the invention also enables a very low-friction and smooth lifting and lowering of the cover unit, so that the effort required for this is reduced.
  • a further advantage is that the wear on the ropes attached to the cover unit can be significantly reduced, since these ropes are no longer wound on rods and are subjected to permanent bending stress and additional friction.
  • An advantageous embodiment of the invention is characterized in that the pull rod is slidably supported in a horizontal plane and deflection devices are provided for the flexible suspension elements attached to the cover unit.
  • the horizontal arrangement of the pull rod enables a very space-saving design and a favorable force distribution along the pull rod.
  • the pull rod is guided by means of roller bearings, each of which consists of a pair of guide rollers arranged on opposite sides of the pull rod and the pull rod being held between them.
  • roller bearings enable a very low-friction and smooth movement of the pull rod.
  • slide bearings for example in or on slide rails.
  • holding and guiding devices for the pull rod and the rope deflection rollers are provided, which have flat or cranked, preferably identical holding plates, between which both a pair of guide rollers for the pull rod and a rope deflection roller for the suspension cables are held.
  • the rope deflection roller is advantageously arranged at a small axial distance from a guide roller and the radial distance between the side cheeks of this guide roller and the rope deflection roller is less than the diameter of the suspension cable guided on the rope deflection roller. In this way, a simple, space-saving and assembly-friendly mounting of the pull rod and the rope deflection roller as well as a secure guidance of the pulling ropes on the rope deflection rollers in the lateral direction is provided.
  • two tie rods parallel to one another and to the longitudinal or transverse sides of the covering unit are provided above an area near the edge of a rectangular covering unit.
  • This enables the cover unit to be raised and lowered in a simple and tilt-free manner.
  • the tie rods and the associated holding elements and cable deflection rollers can be arranged in a freely accessible ceiling area, so that assembly and maintenance are considerably simplified.
  • a uniform load distribution on the individual suspension cables and an even horizontal lifting of the cover unit is achieved in that at least two, preferably four to eight flexible suspension elements spaced apart from one another in accordance with an at least approximately equal tensile load are attached to each cover rod for hanging the cover unit.
  • the pull rod can advantageously be moved in the direction of displacement by means of a cable pulling device.
  • a cable pulling device for example a motor provided with a wind-up device or a manually operated crank device, can be attached to an easily accessible location of the cooling or storage space that is remote from the pull rods.
  • the pull cables of this cable pulling device can also be laid over relatively long distances in a simple manner by means of suitably arranged cable deflection rollers at non-disturbing points in the cooling or storage room.
  • Expansions of the pull cables of this pull cable device are harmless with regard to a uniform raising or lowering of the covering unit if, according to an advantageous embodiment of the invention, the pull cable device, pull rods and flexible suspension elements are arranged symmetrically with respect to the vertical center plane of the covering unit. In this case, the amounts of elongation of the traction cables guided between the drive unit and the tie rods are the same high, so that the tie rods are moved absolutely simultaneously and evenly again.
  • FIG. 1 shows the walls 2 of a cooling or storage room in which two parallel and spaced-apart stack rows 4, 6 of banana boxes or cartons 8 are stored on pallets 10, 12 in the longitudinal direction.
  • cover unit 14 On the two rows of stacks 8, 6 there is a cover unit 14 which has a foam seal 16 on its underside.
  • the cover unit 14 is suspended in a height-adjustable manner from the ceiling 18 of the refrigerator or storage space by means of flexible suspension elements in the form of suspension ropes 40, 42 that can be moved by a lifting and lowering device and is connected at the top to a bellows 20 that runs around the edge of the cover unit 14.
  • the bellows 20 is connected to a ceiling-mounted air cooling unit or an evaporator 22, so that when the cover unit 14 is lowered, the air cooled and circulated by the evaporator 22 is directed outwards, then into a space between the side walls of the cooling or storage space and the rows of stacks 4, 6 downwards, through the stack rows 8, 6 to the central space 24 and from there through corresponding openings in the cover unit 14 in the direction of arrow 28 to the evaporator 22 again.
  • the covering unit 14 therefore causes the cooling air not to be able to circulate above the stack of goods, but is inevitably passed through the partially open banana boxes or cartons 8.
  • the cover unit 14 is a known cover panel, which is designed in a cassette design.
  • the individual cassette elements are arranged in accordance with the stack rows 4, 6 below, in two longitudinal rows, which are at a distance from one another which corresponds to the width of the intermediate space 24.
  • the cooling air can thus flow freely through the central space between the two rows of cassettes.
  • FIG. 1 shows a drive unit 30 of the lifting and lowering device for the cover unit 14.
  • This drive unit 30 can be an electrically operated servomotor or a manually operated device such as a crank mechanism.
  • the drive unit 30 is connected to a winding device 32 for a pull rope 34.
  • This traction cable 34 is connected to traction cables 36, 38 guided horizontally below the ceiling 18 (see also FIGS. 2 and 3), which are attached at their other end to traction rods 62, 64 shown in FIG. 2 and cause a horizontal longitudinal displacement of these traction rods.
  • a plurality of flexible suspension elements 40, 42 in the form of steel cables are fastened to the pull rods 62, 64, which are guided over cable deflection pulleys 44, 46 and fastened at the other end to the top of the cover unit 14.
  • the covering unit 14 can thus be raised and lowered via the suspension cables 40, 42, as will be described in more detail later.
  • link chains can also be provided as an alternative to suspension ropes, wherein instead of the rope deflection pulleys 44, 46, suitably designed chain deflection pulleys are to be provided.
  • Safety ropes 48, 50 can also be seen in FIG. 1, which, however, have no further significance for the raising and lowering of the covering unit 14.
  • the dashed lines 52 show the cover unit 14 in the raised position, in which the goods can easily be brought into the refrigerator or storage room.
  • the cover unit 14 is held by a plurality of suspension cables 40, 42 which are fastened to the two long sides of the cover unit 14 by means of suitable holding members 54, 56.
  • FIGS. 2 and 3 which shows the entire arrangement in a shortened version, only three suspension ropes 40, 42 are shown on each side, but the number of suspension ropes 40, 42 can, however, according to the dimensions and weight of the cover unit 14 and the desired tensile load per suspension rope can be varied.
  • the suspension ropes 40, 42 run vertically upwards from the fastening members 54, 56, are guided over rope deflection rollers 44, 46 and are fastened to the pull rod 62, 64.
  • the attachment of the suspension ropes 40, 42 to the tie rod 62, 64 takes place via fastening members 66 (FIG. 4) which consist of flat elements made of iron or steel screwed onto the tie rod 62, 64 and projecting downward over the tie rod 62, 64.
  • the fastening members 66 have a through opening 68 in the projecting part, through which the end of the suspension cable 40, 42 is passed so that it can be fastened with the aid of a thimble, not shown.
  • the lower end of the suspension cable 40, 42 is attached to the holding members 54, 56 in the same way.
  • a support frame 68 is fastened to the ceiling 18 of the cooling or storage space, which consists of a hollow or steel hollow profile which is square or rectangular in cross section.
  • the holding and guiding devices 70, 72 are arranged above the holding members 54, 56 of the covering unit 14 in such a way that the suspension ropes 40, 42 are guided exactly vertically upwards.
  • the holding and guiding device 70 which is identical to each holding and guiding device 72, has two holding plates 76, 78 which are cranked below the support frame 68 and which are arranged parallel to one another and downwards get narrower. Between the holding plates 76, 78, an upper guide roller 80, a lower guide roller 82 and a cable deflection roller 44 are rotatably supported on axes which are formed by screws 86, 88 and 90, respectively.
  • the guide rollers 80, 82 serve for the vertical and lateral guidance of the pull rod 62 and enable a low-friction longitudinal displacement of the pull rod 62 in the horizontal direction. The lateral guidance of the pull rod 62 is ensured by radially projecting side cheeks 92, 94 of the guide rollers 80, 82.
  • the distance between the side cheeks 94 of the lower guide roller 82 and the rope deflection roller 44 is less than the diameter of the suspension rope 40, so that the side cheeks 94 serve at the same time as a securing means against undesired sliding of the suspension rope 40 from the rope deflection roller 44.
  • flat holding plates can also be used without difficulty, with spacers of suitable thickness between the holding plates and the rollers being able to be used to compensate for the axial play of the guide rollers 80, 82 and the cable deflection roller 44.
  • the tie rod 62 consists of solid material and has a rectangular cross section.
  • the pull rod 62 lies upright on the lower guide rollers 82.
  • differently designed elements such as hollow profiles or solid material elements of other cross-sectional shapes can also be used as pull rods, provided that they have the required strength.
  • the pull cables 36, 38 are fastened and guided in line with the direction of displacement of the tie rods 62, 64 by means of rope deflection rollers 96, 98 having vertical axes of rotation.
  • the cable deflection rollers 96, 98 are located on or in the vicinity of the front end wall of the cooling or storage room, so that the pull cables 36, 38 are guided parallel to the side walls of the cooling or storage room up to this end wall (FIG. 2).
  • the traction cables 36, 38 are guided along the end wall of the cooling or storage space to the center via cable deflection pulleys 100, 102 attached there with a horizontal axis of rotation and from there vertically downwards.
  • the two ends of the pull cables 36, 38 are connected to the common vertical pull cable 34, which cooperates with the winding device 32.
