Definitions

the invention relates to a filling device for bulk goods, comprising a bulk material feed device and one that is movable with respect to the bulk material feed device Filling neck, the filling neck at least one with the bulk material feed device communicating inlet opening and at least one discharge opening for connection with the interior of a container to be filled.
the filler neck is usually made up of several parts and includes one rear opening flap, the bulk material feed device during the process of attaching the bag closes, as well as a front opening flap, which together with the rear opening flap tapers the filler neck towards the sack, so that at the discharge end of the filler neck a closed or to the contour of Opening of the sack adapted beak arises.
the filler neck pivots the filler neck down into a vertical position, while during the Swiveling movement by appropriately controlled movements of the front and the rear opening flap its beak to a defined, the sack mouth adapted cross section opens.
This known filling device for bulk goods has the construction described Disadvantage that no suitable pressure compensation option is provided, which Discharge air displaced from the inside of the sack during the filling process would. It is known that a channel in filling devices for dusty products the bulk material feed device, but this is necessary for the Pressure equalization is not conveniently arranged and is due to the to be filled Sack inflowing material is closed, which is why the bulk material path is completely completed. Due to the closure by the bulk material below the channels described above, the air displaced from the sack must pass through diffuse the contents in order to escape, which leads to an extreme Slowing of the flow behavior of the bulk material leads into the sack. This negative The effect is enhanced if there is any active suction.
the object of the present invention is to overcome the disadvantages mentioned Switch off or mitigate devices of the prior art.
a filling device at the beginning mentioned type is further developed such that the filler neck at least one both communicating with the discharge opening and the inlet opening of the filler neck Has air flow channel. This measure turns the container Air that has been displaced during the filling process should escape as freely as possible and thus the reduction in flow rate inherent in the prior art of the bulk goods reduced or eliminated.
this is at least an air flow channel is formed along an inner wall of the filler neck, wherein it preferably moves from an area at or near the inlet opening of the filler neck an area at or near the discharge opening of the filler neck around which Air exiting the container as completely as possible into the air flow channel bring and derive.
air flow channels in the filler neck be integrated into an air recirculation system in order to prevent material from escaping to the To prevent the environment or the loss of valuable material.
a particularly inexpensive to manufacture and durable construction of the invention Filling device for bulk goods is characterized in that the filler neck is at least partially double-walled and the space between the Walls defined the at least one air flow channel.
the filler neck can be constructed in several parts, wherein According to the invention, at least one air flow channel is formed in each of the parts.
the parts of the filler neck are preferably movable independently of one another.
FIG. 1 shows a first Longitudinal section through a filling device according to the invention
Fig. 2 another Longitudinal section in a plane perpendicular to the sectional plane of FIG. 1
FIGS. 3 to 6 the individual steps of filling a sack in longitudinal sectional views
the Fig. 7 the entire filling device, provided with a suction system and Air recirculation.
the filling device shown has a bulk feed device 1 designed as a fixed chute and one pivotable filler neck (2 + 3), a front opening flap 2 and one includes rear opening flap 3, which are moved by a drive device 4.
a drive device 4 During the process of attaching a bag 16 to the filler neck, the latter is approx. Pivoted 45 ° to the side, whereby the rear opening flap 3 of the filler neck Chute of the bulk material feed device is closed.
the bag 16 to be filled by means of a clamping system 5, 6 at a discharge opening 30 of the filler neck clamped and optionally additionally sealed on the side.
the filler neck tapers by appropriate arrangement of the opening flaps 2, 3 of one of the Bulk material feed device 1 (strictly the chute thereof) facing Inlet opening 31 to the discharge opening 30.
By appropriate tracking of the Opening flaps 2, 3 during the swiveling down of the filler neck in a vertical position becomes the discharge opening 30 of the contour of the bag mouth customized.
Channels 7, 8 are provided in the bulk material feed device 1.
the filling device according to the invention corresponds to the prior art.
the channels 7, 8 in the bulk material feed device 1 are advantageously through double-walled design of the chute are created, according to the invention are now formed in the filler neck 2, 3 air flow channels 9, 10, which are arranged such that it at least in the vertical position of the filler neck by means of seals 11, 12 against the Environmentally sealed to the channels 7, 8 of the fixed bulk material feed device 1 connect and communicate with it.
the filling device is in Filling position, i.e. can be seen with the filler neck 2,3 pivoted vertically downwards, the bag 16 with its pre-opened bag mouth by means of the clamping device 5, 6 is clamped on the opening flaps 2, 3 of the filler neck and by means of clamping and Sealing jaws 13, 14 is laterally sealed.
the pre-opened sack 16 is in Fig. 3 on the filler neck, which the opening flaps 2nd and 3 comprises, attached and by means of the clamping device 5, 6 and the clamping and Sealing jaws 13, 14 closely connected to it.
the product can be filled in by the rear opening flap 3 tightly closed chute 1, or directly from a metering device, not shown, which is above the filling system is ordered, without material at that time by the Dispensing opening of the filler neck emerges.
Fig. 6 shows the filling device with the filler neck in the vertical end position (Filling position) in which the full filling jet of the filling material is placed in the sack 16 flows.
both the air flow channel are the front Opening flap 9 and the air flow channel 10 of the rear opening flap 3 free and together with the channels 7, 8 communicating with them form a path for ventilation or for pressure equalization, which is also available for suction.
FIG. 7 shows an entire filling system, consisting of a funnel 17 Pressure compensation or suction connections 18 and the connected Filling device according to the invention with pressure compensation or suction connections 19.
the filling device corresponds to that of the above description of FIGS. 3 to 6, however expanded with an air recirculation system 21 in the hopper 17, which is arranged above the filling device, the air duct over a switchable valve connected to a vacuum generating device 20 is passed, which is controlled by a signal of pressure compensation operation direct return of the air into the hopper to a defined suction under Using the channels described in Fig. 3-6 switches, the Switching time can be freely selected and adapted to the product.
