Definitions

  • the invention relates to a device for drawing in and compacting solid and elastic materials in the field of collection, sorting, recycling and reprocessing of plastics, textiles, cardboard, paper, aluminum sheets etc. in industry, the processing of animal feed and storage materials for animal stables in agriculture Etc.
  • a method and a device are known in which, by heating, plastic waste is provided in the form of thermoplastic packaging films in blocks, the plastic waste being introduced into a container having side walls, a bottom wall and a stamp; the plastic waste is compressed, heat is supplied to the plastic waste through the side walls of the container to soften the surface of the plastic waste, thereafter the plastic waste is cooled, whereby the softened outer layer becomes hard and the resulting compressed block-like plastic waste can be removed from the container, characterized in that the compression of the plastic waste is carried out at a pressure of 250 to 400 g/cm2, heat is also supplied to the plastic waste through the solid bottom wall of the container and by a stamp to heat the surface of the plastic waste at a temperature of 120 to 180 °C to soften and further melt, the cooling of the plastic waste is carried out by supplying air into the container by means of a fan or blower for 5 to 15 minutes, whereby the softened and melted outer layer becomes hard.
  • the inner walls of the container are
  • the apparatus for the process appears to be of a simple design, but requires, by pre-treating the plastic by heating, for compression with pressure means, Cooling by air with a blower, etc. requires a high level of construction, process engineering and energy expenditure, which is above all costly and time-consuming.
  • EP 0 605 709 B1 is a device for disposing of household waste items, especially in the kitchen, made of materials such as plastic, metal, especially tinplate, glass, in a housing, for example in a piece of furniture, for the direct shredding of the waste items, via a chute of the Shredders can be assigned to several downstream containers for different types of material via a distribution shaft under the shredder.
  • This solution is also structurally complex and only suitable for receiving shredded waste and small amounts.
  • the facility includes a tilting door to receive the waste and a series of waste processing devices in which the waste products are compressed and compacted.
  • This includes several receptacles for receiving various types of solid waste.
  • the device also includes devices for analyzing one or more properties of the waste to be disposed of, devices for monitoring the operations and for interrupting the waste processing process.
  • a device for drawing in and compacting solid and elastic materials was developed, characterized in that the frame consists of two horizontally and oppositely connected longitudinal beams and two oppositely arranged transverse beams is formed, the two Transverse beams are made in one piece and the two longitudinal beams are divided in the vertical direction and the separate parts of the respective longitudinal beam are movably bridged with a spring arranged on both sides, and can be pulled apart and contracted so that the longitudinal beams are parallel to their dividing surfaces on both sides and opposite one another at least by a shaft are connected, on each of which a gear roller is mounted, each of which is composed of a plurality of separate pinions which are arranged to rotate in opposite directions to one another and which mesh in the state of rest, with at least one of the shafts closing as a drive shaft a motor, it is provided that all pinions are spaced on both sides by metal sheets on the shafts, with the metal sheets on the shafts protruding radially beyond the pinions in the direction under
  • the structure is simple and straightforward, and can be manufactured in a kit at low cost.
  • the selection of more or less blunt-faced pinions with tooth flanks of different lengths and shorts up to the shaft surface and their spacing with metal sheets on both sides, as well as the mobility of the frame in the horizontal longitudinal direction, means that the distance between the gear rollers can be automatically mechanically adjusted by the arranged springs , given the strength of the material.
  • the tooth flanks can also be equipped with one or more piercing or cutting elements, such as spikes or pointed blades. The material parts are not crushed, but flattened and pre-compacted, released into the receptacle underneath and further compacted.
  • the metal sheets arranged on the shafts between the pinions of the gear wheel rollers which fulfill two functions. They protrude radially through their outer contour below the gear wheel rollers into the receiving container and are held firmly at the ends on the opposite transverse beams.
  • the sheet metal edges, which point radially downwards, form an interrupted, stable holding surface over the entire horizontal width of the frame, which on the one hand prevents the drawn-in material from getting back into the gear wheel rollers and which, on the other hand, holds the material already in the receptacle in the direction of the same and mechanically compresses the material as the receptacle becomes increasingly full and compacts it more and more.
  • the frame with the vertically separated longitudinal beams is mounted on both sides to be longitudinally movable on any mounting frame on rails or shafts and at least one motor is detachably arranged on the mounting frame for connection to at least one drive shaft.
  • the material receptacle to be placed on the frame and the receptacle arranged on the underside, according to claim 3, ensures easy throwing in of the material to be drawn in and represents a significant safety factor for the users, in that they cannot come into contact with the gear wheel rollers.
  • An additional sensor technology prevents the operator from accessing the gear wheel rollers when throwing the material to be recycled into the material receptacle and when changing the receptacle filled with the compacted material.
  • the metal sheets protruding into the receiving container prevent the material that has already been drawn in from being unintentionally returned to the gear wheel rollers, as a result of which the gear wheel shafts can be prevented from being blocked and these are thus secured against unwanted interruptions or failures of the device. Time-consuming repairs are consequently avoided.
  • the motor can be adjusted in such a way that it switches off in the event of overload, for example when the receptacle is full. This allows for a safety shutdown to avoid engine failure and ensures users know the receptacle is full and needs to be replaced.
  • the design of the assembly frame as a stationary frame or with arranged rollers supports the variability of the use of the frame according to the invention.
  • Fig.1 is a basic perspective top view of the frame 1 according to the invention with two oppositely arranged, centrally divided, closed, longitudinal bars 1.1 and two oppositely arranged transverse bars 1.2 made in one piece.
  • a shaft 5 is arranged, for example, each preferably with a gear roller 2, which is composed of several pinions 2.1 and which are spaced on both sides by metal sheets 6, the metal sheets 6, according to Fig.2 , Protrude vertically below the pinion 2.1 and are held stable with their contour at the end and opposite to the cross members 1.2 of the frame 1.
  • the tooth flanks of the pinion 2.1 can also be equipped with one or more piercing or cutting elements, such as spikes or pointed blades, to stabilize the feeding and pre-compacting effect of the device, for example also for feeding and pre-compacting air-filled packaging materials , to be equipped.
  • the two parts of the oppositely arranged longitudinal bars 1.1 are each bridged by a spring 4, not shown in the drawings, for example a tension spring, which, according to Fig.3 , are stretchable to be pushed apart in the horizontal longitudinal direction when material is inserted between the gear rollers 2 and, after the material has passed through the gear rollers 2, be pulled together again, whereby the gear rollers 2 again mesh.
  • the frame 1 can initially be produced as a kit and is now stored on both sides in any mounting frame 8 with its longitudinal bars 1.1.
  • rails are preferably arranged in the two opposite longitudinal parts of the mounting frame 8, in which the longitudinal beams 1.1 of the frame 1 move when material is picked up between the Can stretch gear rollers 2 in a horizontal plane and contract.
  • a symbolically represented motor 3, preferably an electric motor, is coupled to one of the shafts 5, which serves as a drive shaft, and is fastened to the mounting frame 8 and detachably connected to the frame 1.
  • motors 5 preferably an electric motor
  • a material holder 9 is placed on the frame 1, which is designed, for example, as a concave sheet metal jacket, which bridges the shafts 5 and the upward gear rollers 2 and closes them to the outside.
  • the user can throw material into these from above, which falls into the frame 1 between the gear rollers 2, is caught by them and between the pinions 2.1 and the metal sheets 6 spaced apart into a receptacle 7 arranged under the frame 1, for example a plastic bag, is drawn in. The fuller the receptacle 7 becomes, the surface of the material rises upwards.
  • the sheets 6 protrude from the frame 1 vertically into the receptacle 7 and form, according to Fig.2 and 3 , a broken plane directed vertically downwards, which pushes the surface of the material in the filled receptacle 7 down and progressively compacts it. If the plastic bag used, for example, fills up and the material cannot move any further downwards, the motor 3 is overloaded and automatically stops according to its previously performed adjustment. The users now know that the receptacle 7 has to be replaced and replaced with an empty receptacle 7 . According to Fig.4 the frame 1 is mounted, for example, on a mobile mounting frame 10 . The user can therefore move the completed device to another location where new material is ready to be pulled in and compacted.
  • plastic or rubber rollers with different shapes and surfaces can be arranged on the shafts, which are also spaced apart by metal sheets 6.
  • This roller embodiment allows the strapping to be drawn in vertically and, above all, prevents it from being fed back between the plastic or rubber rollers.
