Abstract
A screw conveyor, for the transport of flowable substances and/or lumps of material, includes a rotatable first screw provided with helical windings arranged in a housing with an inlet opening and an outlet opening. The housing includes an inlet chamber and a pumping chamber between the openings. In at least in the pumping chamber there is a second screw provided with helical windings and arranged for rotation in the opposite direction of the first screw, the screws in the pumping chamber providing a positive displacement pumping function by mutual engagement. Also provided is a cutting device downstream of the pumping chamber and housed within a knife house including an internal channel, where the knife house is connected to the outlet opening. By providing the knife house with second outlet, overfilling of the knife house is prevented. As an alternative means for varying the internal volume of the knife house may be used.
Description
- This application is a continuation of application Ser. No. 10/483,296, which is the National Stage of International Application No. PCT/DK02/00481, filed 10 Jul. 2002 (which is hereby incorporated by reference).
- The present invention relates to a screw conveyor for the transport of flowable substances and/or material having: a rotatable first screw provided with helical windings arranged in a housing with an inlet opening and an outlet opening, the housing including an inlet chamber and a pumping chamber between the inlet and outlet openings; at least in the pumping chamber, a second screw provided with helical windings and arranged for rotation in an opposite direction of the first screw, the first and second screws in the pumping chamber providing a positive displacement pumping function by mutual engagement between the first and second screws when the rotatable first screw is rotated in a first sense of rotation; and a cutting device downstream of the pumping chamber and housed within a knife house, the cutting device including an internal channel, where the knife house is connected to the outlet opening.
- A screw conveyor for the transport of flowable substances and/or material as referred to initially may be used in connecting with meat-mincing machines, but it could also be used in other constructions, in which flowable substances are to be pumped by a positive displacement pumping function. Special problems arise, however, if the flow of substances has to be interrupted (periodically), for instance if the screw conveyor is used for carrying out filling operations in sausage manufacturing. In this application a clip device is coupled to the outlet from the screw conveyor so that the otherwise continuous flow of substance through the outlet from the conveyor is periodically interrupted. This interruption may cause problems with overfilling of the pumping chamber in the conveyor and it has been known to solve this problem by stopping the conveyor during the clipping period.
- It is an object of the present invention to provide a screw conveyor in which overfilling of the pumping chamber—and associated knife house—during the above mentioned interruptions of continuous flow of substance through the outlet section of the conveyor can be avoided without the necessity to stop the rotation of the pump screws in the screw conveyor entirely during periods of interruption of continuous flow of substance, such as during the clipping periods referred to above in connection with the manufacturing of sausages or similar products.
- According to the invention these and other objects are attained with a screw conveyor as set forth hereafter. Various embodiments of the invention are also defined hereafter.
- According to the present invention there is thus provided a screw conveyor for the transport of flowable substances and/or lumps of material, comprising a rotatable first screw provided with helical windings arranged in a housing with an inlet opening and an outlet opening, said housing comprising an inlet chamber and a pumping chamber between said inlet and outlet openings, and at least in the pumping chamber comprising a second screw provided with helical windings and arranged for rotation in the opposite direction of the first screw, said screws in said pumping chamber providing a positive displacement pumping function by mutual engagement between the two screws when said rotatable first screw is rotated in a first sense of rotation, and furthermore provided with a cutting device downstream of the pumping chamber and housed within a knife house, where said knife house is connected to said outlet opening of the screw conveyor, and where said knife house is provided with second outlet means for receiving at least a portion of said substances and/or materials provided to the knife house from said pumping chamber.
- As an alternative to the above second outlet means from the knife house the knife house is provided with a displaceable member—such as a piston—which in one position occupies a certain portion of the internal volume of the knife house and which when activated for instance at the time of interruption of said continuous flow of substance is displaced outwardly from the volume of the knife house, thereby increasing this volume and thus counteracting the tendency to overfilling the knife house during the interruption of the flow.
- The invention will now be described in more detail with reference to the accompanying drawings, in which:
-
FIG. 1 is a cross sectional view of a first embodiment of the invention where the knife house is provided with a buffer valve mechanism with associated actuator; -
FIG. 2 is a cross sectional view of a second embodiment of the invention where the knife house is provided with a return channel from the interior volume of the knife house to the inlet chamber comprising a controllable valve; and -
FIG. 3 is a cross sectional view of a third embodiment of the invention where the knife house is provided with a displaceable piston in one displacement state filling a portion of the interior volume of the knife house. - In the following a detailed description of two embodiments of the present invention is given.
- With reference to
FIG. 1 there is shown a first embodiment of the screw conveyor according to the invention. More specifically there is shown a meat-mincing machine incorporating a screw conveyor and comprising aninlet chamber 4 into which the material to be handled is introduced and in the bottom of which twotransport screws 8 are mounted to move the material towards a set of pumpingscrews 1, 6 provided with inter-engaginghelical windings screws 1, 6 and pumping chamber 5 provides a positive displacement pumping function by the mutual engagement between the twoscrews 1, 6 inside the pumping chamber 5. The first screw 1, thesecond screw 6 and thetransport screws 8 are mounted oncommon axles 9 for rotation by a drive gear and motor. Theaxles 9 are rotated in opposite directions and so are thescrews axles 9. As shown thepumping screws 1, 6 extend approximately one and a half winding out of the pumping chamber 5 and into theinlet chamber 4. - The outlet from the pumping chamber 5 is connected to the inlet of the
knife house 13 comprising aperforated disc 10 co-operating with a set of rotating knives 11 being rotated by theaxle 9. The outlet from the pumping chamber 5 is connected to this cutting device by a relativelysmall volume channel 21 in order to reduce the amount of material left inside this volume when stopping the machine for cleaning/changing handled material. - As mentioned above in the disclosure of the invention a sudden interruption of flow of material out of the
outlet 12 of the machine will cause an unwanted accumulation of material in thechannel 21 and eventual malfunction of the machinery. In order to solve this problem thechannel 21 is according to the first embodiment of the invention provided with a buffer valve system being able to accommodate a sufficient amount of material to prevent the problems of unacceptable accumulation of material in thechannel 21. The buffer valve system is connected to thechannel 21 via a small lateral passage 17 connected to a tubular member comprising apiston 16 operated by a suitable actuator means 22. When the flow of material through theoutlet 12 is interrupted the actuator displaces thepiston 15 in a direction away from thechannel 21 thereby creating avolume 15 of sufficient size to be able to contain the amount of material which is being kept from leaving theknife house 13 through theoutlet 12. The operation of the actuator means is controlled by means of appropriate sensing means that are able to sense the interruptions of the continuous flow of material through theoutlet 12 together with appropriate hardware and software. - An advantageous effect of the operation of the buffer valve system as described above is that it upon activation lessens the pressure exerted on the skin or casing of a sausage during the clip operation by creating a “vacuum” in the
chamber 21, thereby reducing the risk of fractures of the skin of the sausage during the clip operation. - Using the buffer valve system according to this embodiment of the invention it is thus possible to obtain satisfactory operation of the machine during interruptions of continuous flow without it being necessary to stop the rotation of the
axles 9. In order to reduce to amount of material which must be accommodated by thevolume 15 of the buffer valve it is however possible if desired to reduce the speed of rotation of theaxles 9 during clip operations. - After termination of each of the clip operations—and controlled by said hardware/software—the
piston 16 is returned to its initial position thereby returning the accommodated amount of material to thechannel 21 and hence to the cutting means 10, 11. - Referring now to
FIG. 2 there is shown a second embodiment of the screw conveyor according to the invention. According to this embodiment theknife house 13 is still provided with a passage 17 extending from thechannel 21 as in the first embodiment. The buffer valve system is however replaced by achannel 20 providing communication between thechannel 21 in theknife house 13 and back to theinlet chamber 4 via an appropriatecontrollable valve 18 which again can be controlled 19 by appropriate sensing means and hardware/software. This second embodiment of the invention would still solve the problem of making it unnecessary to stop rotation of theaxles 9 during interruptions of substance flow through theoutlet 12 but would not yield the possibly beneficial effect of providing “vacuum” to thechannel 21 in the knife house 5 as described above. - Referring now to
FIG. 3 there is shown a third embodiment of the screw conveyor according to the invention. According to this embodiment theknife house 13 is provided with adisplaceable piston 23 driven by theactuator 22. In the situation shown inFIG. 3 thepiston 23 is displaced to a position where it occupies a portion of thechannel 21 in the knife house 5, but when said interruption of the flow of material through theoutlet 12 takes place thepiston 23 is being displaced outwardly from thechannel 21 driven by theactuator 22 in a manner similar to thepiston 16 in the first embodiment of the invention shown inFIG. 1 . By this outward displacement the volume of thechannel 21 is increased, thus reducing the risk of overfilling of thechannel 21, and if the displacement is carried out fast enough the increase of said volume during a short interval of time will exceed the volume of material provided to thechannel 21 by thescrews 1, 6 during this time interval, and a “vacuum” will be created as described above. - Finally as a completely alternative means compared to those described above the said “vacuum”—and generally an interruption of the positive displacement of material outwardly through the
outlet 12—could be obtained by gradually reducing the speed of rotation of theaxles 9 and finally reversing the sense of rotation of these during the clip operations. - Although various embodiments of the present invention have been shown and described in the preceding parts of the detailed description it is understood that a person skilled in the art may conceive other embodiments of the invention without departing from the scope of the invention as defined by the following claims.
