Definitions

• the invention relates to a packaging machine for sausage production according to the preamble of protection claim 1.
• Generic packaging machines have a filling tube with an inlet and an outlet end.
• a filling machine fills sausage meat into the inlet end, which is then fed through the filling pipe to the packaging machine.
• a sausage casing which is closed on one side is put over the outlet end of the filling tube. The pressure of the sausage meat pushed through the tube gradually pulls it away from the tube.
• the outlet end of the filling pipe is followed by a closure device which closes the filled intestine in sections, e.g. with brackets so that individual sausages are packaged little by little.
• a gut brake is used for this.
• An intestinal brake can be any object that can exert such a frictional force on the outside of the moving intestine.
• rings made of rubber or similar elastic material, which tightly enclose the filling tube, so that the filling tube only surrounds a narrow annular gap. It is also conceivable that the elastic material rests on the tube and that an annular gap only arises when a casing is pulled between the pipe and the casing brake.
• the intestinal Brake consisting of several components, in addition to the active component (s), ie the actual body (s) resting on the intestine, for example a holder for this body and a housing.
• the components of the casing brake are usually made of plastic or rubber. Components made of metal are also known.
• the casing brake can fulfill its purpose, it is arranged in the area of the outlet end of the filling pipe. In this area she is in her working position.
• the filling position is the position of the casing brake within the working position in which the casing brake is when the casing is filled.
• the active components are then on the pipe close to its outlet end.
• known devices provide that the intestinal brake can be easily moved from the filling position into an intestinal change position within the working position. This is achieved by the fact that the casing brake can be moved or swiveled.
• the casing brake can be released from the working position for maintenance and cleaning purposes.
• the object of the invention is to enable automatic determination in a simple manner whether the casing brake is in its working position. It solves this problem by the features of the characterizing part of protection claim 1.
• An inductive sensor in the sense of the invention is a measuring device which uses electromagnetic induction to measure whether metallic objects are in its vicinity.
• the strength of the output signal from the sensor depends in particular on how much and how close metallic material is to the sensor.
• the measuring field of an inductive sensor is the spatial area in which the sensor still detects changes in the position and / or the amount of metallic material, i.e. in which such changes lead to a change in the output signal.
• the metallic component is located on the detachable casing brake.
• the metallic component in the working position of the casing brake, the metallic component is in the measuring field of the inductive sensor, so that it is detected by it.
• the output signal can be used to determine whether the casing brake is in its working position.
• the operator brings the casing brake into its working position, then triggers a programming signal, as a result of which a storage unit records the output signal of the inductive sensor that is then delivered (target signal).
• An evaluation unit then continuously compares the stored target signal with the continuously tapped output signal of the inductive sensor (actual signal). If the evaluation unit detects a deviation, whereby an optionally adjustable tolerance can be taken into account, it delivers a warning signal.
• the latter can be used, for example, to automatically switch off the filling machine and possibly also the closure device, or to block their switching on.
• the metallic component is advantageously arranged rotationally symmetrically with respect to the position of the filling tube in the filling position of the casing brake.
• the advantage achieved thereby comes into play when the active component (s) of the casing brake is or are located on a rotating part which is rotatably mounted about an axis of rotation parallel to the filling tube.
• Such rotatability is desirable in applications in which a casing is twisted onto the pipe, since it then takes up less space.
• the intestine relaxes from this twisting. A shear force then occurs on the active component or components of the intestinal brake, which may lead to tearing of the intestine. This problem is alleviated by said rotatability.
• the superiority of an inductive sensor comes into play when the metallic component is arranged rotationally symmetrically about the axis of rotation.
• the metallic material is always evenly distributed in the measuring field, so that rotation of the rotating part does not lead to a change in the output signal of the inductive sensor.
• an additional inductive sensor is advantageously present, in the measuring field of which there is likewise a metallic component of the intestinal brake.
• An evaluation unit checks whether the sensors also deliver a changed output signal. If this is not the case, one of the sensors is malfunctioning, so that the evaluation unit can trigger a fault signal. If there are several sensors, correspondingly more target signals would have to be recorded and the evaluation unit would have to carry out more comparisons with actual signals.
• each evaluation unit for each sensor with its own target signal and possibly a tolerance, so that each evaluation unit supplies a warning signal that is evaluated by a higher-level evaluation unit.
• the sensors can be connected in such a way that one closes a signal line when it detects a relevant deviation of the actual signal from the target signal, and the other way round opens a signal line in such a case.
• the higher-level evaluation unit can also issue a warning signal in the event of a short circuit or a cable break.
• the casing brakes consist entirely of plastic and / or rubber, but are all surrounded by a metal ring of the same size, the same position and made of the same material.
• the output signal of the inductive sensor is the same for all intestinal brakes. This has the advantage that changing the casing brake does not affect the evaluation of the sensor output signal or the sensor output signals. When changing the casing brake, no new target signal has to be recorded.
• an evaluation unit can differentiate between the individual casing brakes, so that it can be automatically checked whether the selected casing brake fits the application otherwise set on the machine. It is conceivable, for example, that a target signal is recorded for each of the intestinal brakes, which is stored separately. The evaluation unit can then constantly check whether and if so which of the target signals the actual signal corresponds to, and then output a warning signal or a signal which stands for a specific intestinal brake.
• Fig. 1 a schematic representation of a machine according to the invention in side view
• a filling pipe 1 shown cut off in FIG. 1 opens into a casing brake 2, which is in its working position.
• the casing of the casing brake 2 is shown here.
• the active component, not shown, is located inside the housing.
• the casing brake 2 has a circumferential annular groove 3 in its circumference, into which the semicircular arms of a tripod 4 grip. In this way, the casing brake 3 is both rotatably mounted in the stand 4 and can be removed from it, that is to say can be released from its illustrated working position.
• a circumferential metal ring 5 On the casing brake 2 there is a circumferential metal ring 5. This is located in the measuring field of two inductive sensors ⁇ a and 6b, which are arranged in a plane perpendicular to the rotation axis of the casing brake 2 and offset by 45 ° with respect to the rotation axis.
• the sensors 6a, 6b are fastened via a carrier 7 to the closure device 8, which is shown schematically as a cut block.
