Definitions

  • the invention relates to compacting devices according to the preambles of claims 1 and 10 and a method for operating a compaction device.
  • Compacting devices serve the purpose of reducing emptied containers in their volume.
  • the compacting allows space-saving storage or intermediate storage and a simple, cost-effective transport of volume-reduced containers.
  • Such a container may be, for example, a disposable plastic bottle (e.g., PE bottle or PET bottle) or a plastic or metal beverage can.
  • a disposable plastic bottle e.g., PE bottle or PET bottle
  • a plastic or metal beverage can e.g., a plastic or metal beverage can.
  • a compaction device of the type considered finds particular application in conjunction with a reverse vending machine, via which a consumer can deliver empties against return of a deposit.
  • a reverse vending machine accepts empties in forms of containers and leads these containers to a compaction device.
  • a generic compacting device which has two rotating rollers, which rotate in opposite directions and are drawn into the intermediate region to compacting container.
  • a rotating paddle assembly is provided having a paddle shaft and a plurality of paddles connected to the paddle shaft. The paddles feed an empty container to the rollers and press it against the rollers to aid in the collection of the container by the rollers.
  • a first aspect of the present invention provides for disposing the axis of rotation of the paddle shaft at an angle to the axis of rotation of at least one rotating roller, such that the paddle shaft is disposed inclined in the compacting device. Due to the inclined arrangement of the paddle shaft in the compacting device, it is made possible for the collection of a bundle to be carried along with respect to the direction of rotation of the paddle shaft and in the tangential direction with respect to the circular path of the paddles. As a result, the risk of rebounding of containers on the front sides of the paddle is significantly reduced, so that the feed conditions are significantly improved.
  • the axis of rotation of the paddle shaft and the axis of rotation of the at least one rotating roller at an angle between 15 ° and 75 °, in particular at an angle between 30 ° and 60 ° to each other.
  • This angularity can be illustrated by considering the practice of the usual case that the axis of rotation of the at least one rotating roller extends in a horizontal plane of the compacting device.
  • the axis of rotation of the paddle shaft is then inclined between 15 ° and 75 °, in particular between 30 ° and 60 ° relative to the horizontal plane. At an inclination of 0 °, the axis of rotation of the paddle shaft would be parallel to the horizontal plane (which case according to the invention is just excluded). If a plurality of rotating rollers are provided, all axes of rotation of the rotating rollers extend in the horizontal plane of the compaction device.
  • the paddles of the paddle arrangement are adapted to draw in the container into the device to perforate and compact before it is fed to the at least one rotating roller.
  • the paddle arrangement thus fulfills three functions. First, the realization of a safe collection of the container. Second, a first evacuation of the container including, if necessary, the provision of perforations. Third, the provision of a first deformation work for compacting the container.
  • the paddles of the paddle arrangement have spikes or the like at their respective end face for the perforation and evacuation of the container. It is also provided in one embodiment that the paddle shaft rotates at a higher rotational speed than the at least one roller.
  • the container supplied to the paddle assembly thus already undergoes a perforation and compression before it is fed to the at least one roller for compaction.
  • the paddle assembly is insofar as a pre-compressor of the compacting device, which compresses the container to a certain extent and presses flat and then fed to a roll column.
  • the compacting device comprises two rollers arranged in parallel, which are referred to as tapered rollers are formed.
  • the two tapered rollers are arranged in pairs with opposite cone orientation, whereby a parallel arrangement of the roller axes is present despite the design as tapered rollers.
  • the two parallel rollers are located in a horizontal plane of the set up for the operation Kompakt istsvorraum.
  • a variant of this embodiment provides that also the paddles of the paddle arrangement are funnel-shaped, i. the width of the paddles increases from a front end of the paddle shaft to a rear end of the paddle shaft. It can be provided that the paddles of the paddle arrangement have the same conicity as the tapered rollers.
  • a further embodiment provides that the paddle shaft is mechanically coupled to one of the rotating tapered rollers.
  • Such a coupling can take place, for example, via a spur gear toothing of the paddle shaft, which meshes with a toothing of one of the tapered rollers.
  • Such mechanical coupling allows easy driving of all rotating parts of the compaction device.
  • the ratio between the rotational speed of the rollers and the rotational speed of the paddle shaft can be adjusted for example via the gear ratio of a toothing of paddle shaft and tapered roller.
  • the compacting device comprises two rollers arranged in parallel, which are formed as tapered rollers, wherein the two tapered rollers are arranged paired with opposite cone orientation.
  • a container to be compacted is conveyed by a roller gap formed between the conical rollers.
  • This solution according to the invention is associated with the advantage of improved perforation or improved tearing of the container. This is due to the fact that the container is exposed in the nip between the two tapered rollers additional forces due to the fact that the tapered rollers at the outer edges have different rotational speeds and only in the middle have the same rotational speed. As a result, the container is on the one hand applied to the outer edges of the tapered rollers with additional tensile forces and centered on the other to the center of the roll.
  • the compacting device according to the second aspect of the present invention using two tapered rollers is combined in an advantageous embodiment with the first aspect of the invention of providing a tilted paddle shaft.
  • the container is directed at entry to a peripheral region of a tapered rollers in which the rotational speeds of the two tapered rollers differ most, so that strong forces acting on the container and a good perforation is provided.
  • the second aspect of the invention can also be implemented without the first aspect of the invention, ie without an inclined arrangement of the paddle shaft.
  • the tapered rollers are designed such that the container experiences a Verschränkungsexcellent when passing the tapered rollers.
  • a Verschränkungsexcellent a section is called, which leads to an entanglement of the slotted and perforated container to the effect that a springing of the container after leaving the compaction device is largely prevented.
  • the individual perforated material regions of the container thus entangled with each other such that a springing is not or only to a small extent possible. This is associated with the benefit of sustained volume reduction even after leaving the compacting apparatus.
  • the invention provides a method of operating a compacting apparatus according to claim 1.
  • the container is fed along with respect to the direction of rotation of the paddle shaft of the paddle arrangement.
  • the container is thus fed to the compaction device at a speed which has at least one component of movement which coincides with the direction of rotation of the paddle shaft.
  • the container with the same motion vector, which also has the paddle of the paddle shaft the paddle assembly is supplied.
  • the supply of the container takes place in the tangential direction with respect to the circular path that make the paddles.
  • This tangential delivery of the container further reduces the risk of collision of the container with one of the paddles of the paddle assembly when feeding the container. Due to the tangential intake of the container there is a synchronism of the movement of the container and paddle of the paddle shaft.
  • a conveyor which supplies the container of the compaction device is removed in an oblique orientation, in particular at an angle between 30 ° and 60 °, for example at an angle of 45 ° relative to the horizontal plane of the compaction device, and in this orientation falls into the paddle arrangement of the compaction device.
  • This ensures that the container in addition to its supply in the tangential direction also equal to a suitable orientation for the supply to the at least one roller.
  • a corresponding guide contour can be provided on the conveyor, which removes the container at a certain angle of the conveyor.
  • FIG. 1 1 shows a compacting apparatus 1 comprising a roller assembly 2 with two rotating rollers, a drive device 3, a paddle arrangement 4, a feed chute 5 and a peripheral housing 6.
  • the device 1 further comprises a base plate 7, on which the drive device 3 is arranged and which supports the housing 6.
  • the drive device 3 comprises a motor drive 31 which drives a drive shaft 32.
  • the drive shaft 32 is coupled, for example via a worm gear 33 with an output shaft 34.
  • the output shaft 34 drives the one roller 21 of two drive rollers 21, 22 forming the roller assembly 2.
  • the two drive rollers 21, 22 are horizontal, that is arranged in the plane of the base plate 7 and parallel to each other. Their respective axes of rotation X1 and X2 are accordingly parallel.
  • the two rollers 21, 22 are each formed as tapered rollers, i. they have a conical shape. In this case, they are arranged with opposite cone orientation paired with each other, so that despite the design as a tapered rollers, a parallel arrangement of the axes of rotation X1, X2 is present.
  • the tapered rollers 21, 22 each have a basic roller body 210, 220 with a conical shape, on whose circumference a plurality of mandrels 211, 221 are formed.
  • a nip 23 through which a container can be promoted.
  • the nip 23 is in the illustration of FIG. 2 only indistinct to recognize, since the individual spikes 211, 221 of the tapered rollers 21, 22 protrude into the nip 23. A nip 23 is nonetheless formed, so that a container through the gap 23 can be promoted.
  • the coupled to the output shaft 34 tapered roller 21 further has at its front end a toothed wheel 212, which has an external toothing.
  • This gear wheel 212 meshes with a further toothed wheel 222, which is arranged on the one end face of the other tapered roller 22.
  • the gear disk 222 is arranged at the front end of the tapered roller 22, at which the cone of the roll body 220 has its largest diameter. Accordingly, the toothed wheel 212 of the tapered roller 21 is disposed at that end of the tapered roller 21 at which the cone of the roller base body 210 has the smallest diameter.
  • the second tapered roller 22 has at its other end face a conical toothing 223 which meshes with a toothing 43 of a paddle shaft of the paddle assembly 4, with respect to the FIG. 3 will be explained.
  • the power transmission of the components of FIG. 2 is such that a torque of the drive shaft 32 is transmitted via the worm gear 33 to the output shaft 34.
  • the first tapered roller 21 is set in rotation.
  • the rotation of the tapered roller 21 is transmitted via the gear wheels 212, 222 to the second tapered roller 22, which rotates at the same speed, but in opposite directions.
  • the rotational movement of the second tapered roller 22 is transmitted via the teeth 223 and 43 to the paddle shaft of the paddle assembly 4. In this case, a desired transmission ratio can be adjusted.
  • the paddle shaft rotates at a higher rotational speed than the tapered rollers.
  • the rotational speed of the paddle shaft is twice or generally n times the rotational speed of the tapered rollers 21, 22.
  • the FIG. 3 shows in addition to in terms of the FIG. 2 This consists of the already mentioned paddle shaft 41 and a plurality of paddles 42. In the illustrated embodiment, but not necessarily, three paddles in a symmetrical arrangement, that are circumferentially evenly connected to the paddle shaft 41.
  • the paddle shaft 41 forms at its lower end already in relation to the FIG. 2 mentioned spur gear teeth 43, which meshes with the conical toothing 223 of the second tapered roller 22.
  • the paddles 42 of the paddle assembly 4 are themselves funnel-shaped, and their radial distance from the paddle shaft 41 accordingly increases steadily from a minimum at the lower end of the paddle shaft 41 to a maximum. It is further provided that the paddles 42 of the paddle arrangement at their respective end face thorns 421 form, which serve a perforation and evacuation of a container.
  • the axis of rotation X3 of the paddle shaft 43 at an angle, that is not parallel to the axes of rotation X1, X2 (see. FIG. 2 ) of the tapered rollers 21, 22 extends.
  • a low overall height of the compacting device 1 is achieved.
  • the collection of a container is improved and made safer, as in relation to the FIGS. 6 to 8 will be explained.
  • FIG. 4 shows the compaction device of FIG. 1 in a representation obliquely from above, in which the intake shaft 5 and their interaction with the paddle assembly 4 is better recognizable.
  • the feed chute 5 tapers downwards, ie in the direction of the tapered rollers 21, 22, wherein the feed chute 5 forms a sliding surface 51, along which a container to be compacted is fed to an end region of the roller assembly 2, ie a region of the roller assembly 2 in which the rotational speeds of the two tapered rollers 21, 22 differ the most.
  • the rotational speeds of the two tapered rollers 21, 22 are identical only in the middle of the tapered rollers 21, 22.
  • the paddles 42 likewise form part of the catchment area and, together with the intake shaft 5, form a downwardly tapering catchment area.
  • FIG. 5 corresponds to the representation of FIG. 4
  • only the tapered rollers 21, 22 and the paddle assembly 4 with the paddle shaft 41 and the paddle 42 are shown in detail.
  • the inclined arrangement of the paddle shaft 41 in the compacting device 1 can be seen well.

  • the container 8 has the same motion vector as the paddle 42 of the paddle assembly 4, so that the supply of the container 8 in the tangential direction with respect to the circular path that run the paddles 42 takes place. This prevents that the container 8 rebounds on the individual paddles 42, in particular on the end faces of the paddles 42 and thus the compacting device 1 can not be fed properly. Due to the inclination of the paddle shaft 41, such a tangential indentation can be achieved despite the vertical movement component of the container 8 caused by gravity.
  • the container 8 is then, as already explained, drawn in by the paddles 42, in particular the mandrels 421 arranged on the end face of the paddles 42, in the direction of the two tapered rollers 21, 22 and in the process evacuated and perforated by the mandrels 421, wherein already a first compression of the container 8 takes place.
