Definitions

  • the invention relates to a device for mechanical comminution of Plastic parts and / or sprue.
  • Known devices of the type mentioned initially include a comminution device with an inlet, a crushing chamber and an outlet.
  • a parts feeder for feeding the plastic parts and / or sprues attached.
  • the other end are conventional parts feeders open, from where they with plastic parts and / or sprues.
  • the alternative second solution has the disadvantage that the device is very bulky, particularly high-rise. Arranging a separator above the high-rise shredder with parts feeder problematic for reasons of space and stability. Will the separator Arranged next to the shredder must have driven conveyors be provided to feed the plastic parts or sprues of the parts to hand over.
  • the object of the present invention is to provide a device for Shredding to be specified with an even better secured parts feeder at the same time a more compact arrangement of separating device and shredding device allowed.
  • a key concept of the present invention is to connect the separating device and the reducing device as a compact unit and not only connect the parts feeder to the separating device, but also to provide means for non-intrusive fastening of the parts feeder to the separating device. Due to the fact that the separating device is secured to the parts feed in a tamper-proof manner, the conventionally open end of the parts feed is eliminated. Reaching in is no longer possible with the parts feeder connected to both the separating device and the shredding device, so that neither the installation of baffles in the parts feeder nor the criticized high-rise training is necessary. As a result, the parts feed can be made shorter and with a freer passage, so that the combined unit comprising the separating device and comminuting device together take up considerably less space.
  • the arrangement according to the invention furthermore introduces dirt together with the parts to be shrunk into the shredding device further complicated or prevented. Soiling of the plastic granulate can lead to defects in the plastic part for which the shredded part Plastic is used, and in the worst case against claims for recourse the manufacturer of the plastic part.
  • the parts feed is on the comminution device and / or the separating device by means of a coupling device releasably attached.
  • the coupling device allows a quick, preferably tool-free loosening of the parts feed. Installation, retrofitting or replacement individual components is in a quick-release coupling device easy and convenient.
  • the separating device two alternative connection positions are provided, each with a first Coupling element are equipped. At these connection positions can be over the first coupling elements using the assigned end of the parts feed connect a corresponding second coupling element.
  • first connection position of the separating device for feeding larger geometrically
  • second connection position for feeding geometrically smaller parts intended.
  • the compact unit consisting of a separator and shredder can therefore be easily shredded from larger Change parts to shredding smaller parts. They are different Variants conceivable that make this possible in a simple manner.
  • the parts feed is on the comminution device pivotally attached such that after loosening the coupling device when swiveling the parts feed, either the first and the second connection position of the separating device can be reached.
  • the compact unit of can thus be pivoted shredding larger parts to shredding smaller parts (or vice versa) switch.
  • the change can be made between the first and second connection position also by a relative shift reach between separating device and shredding device.
  • the separating device and comminuting device are relative slidably arranged to each other.
  • guidance is preferred, in particular guidance Linear guide provided, which is preferably a tool-free movement of the Crushing device allowed relative to the separating device.
  • the Parts feed can either be designed so that there is a separating device and shredding device next to each other or alternatively the shredding device Arrange directly below the separator.
  • the order according to the first alternative is necessary with regard to Prefer maintenance and cleaning.
  • the arrangement according to the second Alternative allows a particularly compact design with an extremely short Parts feed, which may already be on the separating device and / or the shredding device could be formed. Also in the arrangement According to the first alternative, it would in principle be conceivable to feed the parts directly to be molded on the separating device and / or the comminuting device.
  • a protective device is expediently provided, for example by means of an electric motor brake, the safety of the operating personnel even when Guaranteed opening of the quick-release connection.
  • connection devices mechanically connect with each other.
  • the Connection devices quickly releasable connecting elements, so that here too rapid separation or regrouping of the unit from the separation device and shredding device is possible.
  • the tamperproof shielding when connected the separating device and the shredding device via the parts feeder both through the parts feed itself and also as a supplement or alternative can be guaranteed by other shielding devices.
  • FIG. 1 shows an embodiment of the device according to the invention, in which a separating device 16 next to a shredding device 11 is arranged.
  • the crushing device 11 and the separating device 16 are connected to one another via a parts feed 15.
  • the parts feeder 15 transfers plastic parts and / or sprues to be shredded to the shredding device 11.
  • the parts feed 15 is both direct connected to the comminution device 11 and the separating device 16. Intervention in the shredding device 11 is thereby made impossible.
  • the parts feed 15 is so stable that it Shredding device 11 and the separating device 16 simultaneously mechanically connects sufficiently securely.
  • additional connection devices 24 may be provided.
  • the device shown in Fig. 1 has between the parts feed 15 and the Separating device 16 has a coupling device 18, which is a tool-free Connection or disconnection of the parts feed 15 permitted by the separating device 16.
  • a protective device 23 ensures that when the parts feeder is open 15 can not pose any danger from the shredding device 11.
  • a safety switch is provided, for example, the in conjunction with a suitable electrical protection unit of the shredding device, e.g. an electric motor brake, the safety of People also when opening the quick-release connection of the parts feeder 15 guaranteed while the shredding device 11 is running.
  • FIG. 2 shows an alternative embodiment to that of FIG. 1, in which the shredding device 11 not next to, but directly below the separating device 16 is arranged.
  • the device according to the invention even more compact, so that more floor space can be saved.
  • the embodiment of FIG. 1 for cleaning and maintenance work somewhat more accessible.
  • 3 to 5 are different embodiments of the invention in one compared to the views from FIGS. 1 and 2 orthogonal view.
  • the shredding device and the separator basically depending on the size of the shredded Plastic parts or sprues joined together in two different positions become.
  • the Separating device as known per se - two screw conveyors rotating against each other 25, 26. Smaller parts or sprues fall between the rotating ones Screw conveyors 25, 26 pass through and enter a funnel-shaped trough 27.
  • At the lower end of the tub 27 is an outlet with a first coupling element provided to connect the parts to the guide 15 if necessary.
  • the parts feed 15 is arranged on a in the collecting box 28 Coupling element connected.
  • the shredding device 11 is released in brought the desired position and then fixed again.
  • the shredding device 11 and the Separating device 16 in a fixed relative position to one another.
  • the parts feed 15 on the comminution device 11 is pivotally mounted and facing the shredding device 11 Opening of the parts feed 15 eccentrically above the pivot axis of the shredding device 11 is arranged.
  • the shredding device 11 can be relative to Move separating device 16 by means of a linear guide 22. This leaves the device according to the invention is tool-free in a few simple steps from the first connection position to the second connection position or vice versa switch.
  • the danger area of the shredding device can thus be through the parts feed itself or connection with other elements of the separating device be safely shielded. It becomes a complete unit consisting of a separator and shredding device proposed, which is compact in the result and takes up little floor space. Simultaneously with the proposed Construction increases security.
