Definitions

  • the invention concerns a clip machine for dividing up and closing tubular packagings filled with filling material, and a method of controlling such a clip machine.
  • the invention concerns a clip machine for dividing up and closing tubular packagings filled with filling material by means of closure clips, comprising at least a first and a second closure tool unit which for setting and closing at least one closure clip (clip) are reversibly movable relative to each other between an open position and a closure position.
  • the invention further concerns a method of controlling such a clip machine.
  • a clip machine of the kind set forth hereinbefore is typically used to close bags or tubular packagings (tubular casing or sausage case) filled with liquid to thick-pasty or also (in part) granular content.
  • the filling material is introduced into the packaging and thereafter, in the case of a tubular packaging, divided up into portions by means of displacement elements.
  • the displacement elements constrict the tubular casing in the radial direction and displace the filling material which is in the constriction region in the axial direction, with respect to the tube axis.
  • a tubular plaited portion is thus formed in the constriction region.
  • closure elements such as closure clamps or clips are applied to the tubular plaited portion formed, by means of the two closure tools which are moved relative to each other.
  • the closure tools respectively include in paired relationship a punch and a die, between which the clip is converted in shape during the closure operation until the closure position is reached (reversal point of the movement). After closure the closure tools are moved back into their starting or open position.
  • closure spacing or closure height that is to say the smallest distance between the punch and the die when the clip is closed around the tubular plaited portion, is checked and adjusted. As is known for that purpose the rest position of at least one of the closure tools is altered.
  • EP patent application 0 900 733 discloses a clip machine having a distance sensor for detecting the closure spacing with a distance sensor arranged stationarily with respect to the closure tools, and a reference surface. That makes it possible to actually detect a value corresponding to the closure clip height.
  • the distance sensor is directly subjected to the acceleration forces acting on the closure tools as it is fixedly connected thereto and is moved therewith. Depending on the sensitivity of the respective sensor the function thereof can be adversely affected thereby or the sensor itself can be damaged, whereby reliable accurate detection of the closure spacing is no longer guaranteed.
  • a further possible error source is formed here by the connecting lines of the distance sensor, which by virtue of the movement of the sensor in each closure operation are also moved and deformed and in that way can be damaged.
  • German laid-open application No 10 2005 026 219 (US 20060272374) further discloses a clip machine having a measuring device which detects the resilient deflection or spring travel of a spring upon closure of a clip, deduces the closure force therefrom and compares it to predetermined values. If a predetermined value for the spring travel is exceeded the rest position of one of the closure tools can be re-adjusted manually or by motor means. If the spring travel exceeds a maximum value it is provided that the clip machine is stopped.
  • the arrangement further has a position sensor for monitoring the rest position of the closure tool. That known clip machine permits an approximately constant pattern in respect of the spring travel and thus indirectly the closure force.
  • the measuring device of that clip machine is however of a complicated structure with many components which can represent potential sources of error.
  • the object of the present invention is to improve a clip machine and a method of controlling that clip machine such that the risk of misdirected manipulation is lessened, the loading on the closure tools is reduced and closure of a closure clamp or clip around the packaging casing is made into a more reliable procedure.
  • a clip machine for dividing up and closing tubular packagings filled with filling material by means of closure clips comprising at least a first and a second closure tool unit which for setting and closing at least one closure clip (clip) are reversibly movable relative to each other between an open position and a closure position.
  • at least one piezoelectric sensor which is connected to one of the closure tool units and which is adapted to measure a closure force applied upon closure of a closure clip and to output a measurement value representing the closure force.
  • a piezoelectric sensor includes one (or more) so-called piezoelectric crystal, on the crystal surface of which, when a mechanical strain is involved, there occur electrical charges, the magnitude of which is proportional to the strain. In the above-described arrangement the charge produced is therefore proportional to the closure force.
  • piezoelectric crystals such as quartz, piezoelectric ceramics but also all other suitable piezoelectric materials.
  • a piezoelectric sensor arranged in the proposed fashion is capable at any time of determining the force just acting on the closure clip. In that way the closure operation can be terminated immediately when a prescribed value for the closure force is reached. That therefore in practice excludes the closure force exceeding the predetermined value.
  • the piezoelectric sensor is arranged in at least immediate proximity with the main flow of the closure force.
  • the piezoelectric sensor is disposed directly in the flow of force acting on the closure clip. Therefore the same force or a force of the same magnitude acts on the piezoelectric sensor as on the closure clip. Additional recalculation or modification of the value delivered by the piezoelectric sensor in order for example to be able to take into consideration geometrical factors of a closure lever such as flexing by virtue of a lever action are not required. That means that determining the closure force is simpler and more accurate.
  • the piezoelectric sensor in the rest position of the closure tool unit the piezoelectric sensor is subjected to a prestressing with in a further configuration can be adjustable. That prestressing simulates an initial force which is already present, in which case the fact of that force falling below the specified value can indicate a technical problem such as jamming of a closure tool, from which a tensile stress can result.
  • the display of such a value which differs from the selected prestressing can lead to a corresponding reaction on the part of the control system.
  • the measurement range of the piezoelectric sensor can be displaced by virtue of the adjustability of the piezoelectric sensor prestressing, thereby permitting adaptation of the piezoelectric sensor to the control arrangement or to different clip sizes.
  • prestressing of the piezoelectric sensor can prevent an unwanted change in the sign of the measurement values, as can occur in the case of a wrongly adjusted variation in the neutral position or a defective variation in the neutral position which is caused by fluctuations in the ambient conditions. That can eliminate a further possible source of error in terms of measurement.
  • the piezoelectric sensor is in the form of an encapsulated sensor. In that way it is protected from almost all environmental influences whereby the accuracy of the measurement values can be increased. In particular the piezoelectric sensor can be efficiently protected from moisture in that way as clip machines have to be regularly cleaned for hygiene reasons.
  • the piezoelectric sensor is arranged on the support mounting of the closure tool units or is arranged stationarily relative to the machine housing, whereby the feed lines of the piezoelectric sensor can also be arranged stationarily relative to the machine housing. Both the piezoelectric sensor and also the feed lines are therefore not moved with the closure tools and are not subjected to the acceleration forces occurring in that case. That arrangement protects the piezoelectric sensor and the feed lines from damage due to the acceleration forces which occur and thus permits reliable measurement.
  • the piezoelectric sensor is moreover advantageous for the piezoelectric sensor to be mounted in a protected position in order to additionally protect it from damage due to moving parts. That can be implemented by a covering for the piezoelectric sensor.
  • the piezoelectric sensor however can also be disposed in an opening or recess in the support mounting or in the machine frame.
  • a control unit with an event data memory which is adapted to at least temporarily store the current measurement value and compare it to a first selected value range. With sufficient memory space it is also possible to store series of measurement values over a prolonged time.
  • control unit is adapted to compare the current measurement value with a second selected value range and to output a control signal if the measurement value leaves the second selected value range.
  • a third selected value range characterizes an increased closure force which could lead to damage to the clip machine, the closure clip or the packaging material. Therefore in an embodiment according to the invention the control unit is adapted to compare the current measurement value with a third selected value range and to stop the clip machine if the measurement value leaves the third selected value range.
  • control unit is adapted to record the variation in the closure force over travel and/or time and to analyze it in order upon deviations from a predetermined variation to output a signal which displays said deviation and/or acts in a predetermined manner on the clip machine.
  • Analysis of the force-travel pattern and/or the force-time pattern permits conclusions to be drawn about the wear for example of the closure tools or also the quality of the closure clips.
  • a position sensor by means of which the rest position of at least one closure tool unit can be detected.
  • the position sensor is connected to the control unit and can output a corresponding readiness signal upon detection of the at least one closure tool unit.
  • the position sensor used can be for example a rotary sensor, the signal of which can be used to adjust the rest position of the at least one closure tool unit.

  • the punch 110 is driven by way of an elbow lever arrangement 112 .
  • the elbow lever arrangement 112 has a first lever 114 and a second lever 116 which form a common elbow joint 118 . With its end remote from the elbow joint 118 the lever 114 is pivotally connected to a journal 122 stationarily connected to the punch 110 .
  • the second lever 116 is pivotally connected to a support mounting 126 , with its end opposite to the elbow joint 118 .
  • the elbow lever joint 118 is bent or straightened by a force applied by way of a coupling bar 120 the punch 110 moves up and down between an upper open position and a lower closure position. In that case the punch 110 which is fixed on a punch carrier 124 is guided telescopically by a cylindrical guide 125 which is fixedly connected to the machine housing (not shown in greater detail).
  • a piezoelectric sensor 138 is arranged at the support mounting 126 . It is fitted into a recess in the support mounting 126 , which in the illustrated embodiment is formed by two projections (not identified).
  • a fixing device 140 (also not shown in greater detail) holds the piezoelectric sensor 138 in its position in the recess. It is possible by means of the fixing device 140 to brace the piezoelectric sensor 138 between the projections and thereby to act on it with a prestressing.
  • the fixing device 140 can be for example in the form of a manually actuable adjusting screw, by means of which the prestressing can be freely selectably adjusted.
  • the piezoelectric sensor 138 is an autonomous measurement system, that is to say the closure force can be ascertained therewith, independently of further system components.
  • the support mounting 126 is connected directly and rigidly to the machine housing by way of an adjusting drive 142 , 144 .
  • the adjusting drive 142 , 144 includes a drive motor 142 , for example a stepping motor, and an adjusting device 144 .
  • the stepping motor 142 drives the adjusting device 144 which for example can be a per se known adjusting screw or by way of a toothed belt which operates in slip-free fashion.
  • the adjusting device 144 which is set in rotation by the drive motor 142 about its longitudinal center line which coincides with the longitudinal center line of the cylindrical guide 125 displaces the support mounting 126 along its longitudinal center line with respect to the machine housing. That permits adjustment of the rest position of the punch 110 .
  • the closure force applied upon closure of a clip is transmitted to the housing by way of the elbow lever arrangement 112 and the support mounting 126 .
  • the support mounting 126 is compressed. That compression effect is slight but is sufficient to exert a force on the piezoelectric sensor 138 arranged in the recess of the support mounting 126 . That causes the piezoelectric sensor 138 to be deformed and it outputs an electric signal corresponding to the force causing the compression effect, that is to say the closure force.
  • a position sensor 132 is so arranged on the machine housing that it is capable of establishing the rest position of the punch carrier 124 and thus the punch 110 secured thereto.
  • this is a contactlessly measuring sensor such as for example an optical or capacitive sensor. It is however also possible to use a mechanically operating sensor.
  • a rotary sensor as the sensor for detecting the rest position of the punch carrier 124 and the thus the punch 110 secured thereto, by means of the signal of which the stepping motor of the adjusting drive 142 , 144 can also be directly actuated.
  • the closure force applied in a closure operation is determined in the above-described manner solely by the piezoelectric sensor 138 arranged in the recess in the support mounting 126 . That very simple measurement arrangement avoids possible sources of error and improves the accuracy of the measurement result as the number of deformed components has been reduced and it is possible to dispense with additional or unnecessarily complicated measurement devices. Adjustment or correction of the rest position of the punch 110 is effected for example in the manner described in greater detail with reference to FIG. 2 .
  • the portion of a further embodiment of the clip machine according to the invention, shown in FIG. 2 substantially corresponds to the embodiment of FIG. 1 .
  • Components which are identical or involve the same function are denoted by the same references.
  • the clip machine of FIG. 2 has the first closure tool unit which is identical to the FIG. 1 embodiment, with the punch 110 , the elbow lever arrangement 112 , the adjusting drive 142 , 144 and the piezoelectric sensor 138 arranged on the support mounting.
  • the support mounting 126 is connected to the machine housing by way of a support and mounting device 128 . More specifically the support and mounting device 128 has inter alia a spring 130 and the adjusting drive 142 , 144 .
  • the spring 130 is a compression spring which at its end opposite the support mounting 126 is supported against a housing 134 fixed stationarily to the machine housing of the clip machine 100 .

  • the selection of one or more value ranges from the database is effected in dependence on the rest position value outputted by the position sensor 214 and/or on the basis of a read-in item of product information.
  • the product information can be directly inputted manually by way of an input unit 216 for example before the commencement of production. Alternatively the product information can also be automatically read in out of a product information database (not shown).
  • a comparison device 218 of the control 200 makes a comparison of the value range or ranges with the measurement value which is outputted by the measuring device 220 and which represents the closure force applied upon closure of a clip.

  • the comparison device 218 makes the choice to which of the components 222 , 224 , 226 and 228 is outputted, on the basis of the comparison of the measurement value obtained with the measuring device 220 with a plurality of value ranges, as described by way of example with reference to FIG. 4 .
  • the value ranges are typically different but can also be partly or completely coincident.
  • the display device 222 displays the event. That can preferably be effected optically but also or additionally acoustically.
  • a display or screen in combination with an acoustic warning signal is appropriate for that purpose.
  • Each production start S 300 involves beginning initialization of the clip machine, which includes inter alia the control method according to the invention.
  • a production selection is made with initialization at S 304 .
  • the set-up method begins with determining the rest position S 302 by means of the position sensor which is coupled to an adjustable closure tool unit and which produces and outputs a rest position value representing the rest position of the set closure tool unit.
  • a next method step S 306 involves checking whether the determined rest position value suits the selected product. If that is not the case the rest position is set in the method step S 308 .
  • Setting is effected by means of a setting drive which can be controlled manually or automatically by a signal outputted by the control system in accordance with the product selection. In a further alternative any motor drive can be regulated by way of a rest position value which is virtually permanently detected so that it moves the closure tool into the desired reference position which suits the selected product.
  • the closure force is measured at S 310 with the first closure operation (and at each further closure operation).
  • the measured closure force is compared in the interrogation step S 314 to the value range which was previously selected in the step S 312 and which is ascertained on the basis of the product selection made in step S 304 . If the comparison shows that the measured closure force lies outside the selected value range 3 the clip machine is stopped in the step S 316 and the event is protocolled and/or displayed in the step S 318 .
  • the closure force is compared to a second selected value range. If the comparison shows that the closure force is outside the value range 2 the rest position is re-adjusted in the step S 322 and the event protocolled and/or displayed in the step S 324 .
  • step S 320 If the checking procedure in step S 320 shows that the measured closure force is also within the selected value range 2 then in a next step S 326 a check is made to ascertain whether it is in a first selected value range.

  • step S 330 involves querying whether production is concluded and/or whether in the meantime a manual command has been given to stop the machine. The same interrogation, whether production is concluded or whether a stop command has issued, in step S 330 is also effected in relation to step S 322 of adjusting the rest position if the measured closure force is outside the selected value range 2. If that is the case the machine is stopped in step S 332 . Otherwise the next closure cycle is set in operation with step S 310 .
  • the value ranges are so staggered that, when the values rise above or fall below first limit values, that is only protocolled and/or displayed in order for example to obtain an indication of a possible error source, the effects of which however are acceptable in regard to wear of the clip machine and the durability of the closure produced.
  • the closure force rises above or falls below second limit values which generally cover a greater value range
  • the rest position is re-adjusted in order to bring the closure force back into an acceptable value range again. Whether the adjustment of the rest position was sufficient is checked in the next closure cycle by again measuring the closure force. That produces a closed regulating circuit. It will be noted however that if the closure force should be outside a still wider third value range, which generally occurs as a consequence of a malfunction or serious incorrect operation, the machine is stopped immediately to be able to remove the error before the production or indeed the machine can suffer damage.
  • Evaluation of those relationships makes it possible to obtain information about the quality of the closure. It is also possible to infer possible quality fluctuations in regard to the closure clips or wear of the closure tools, from deviations from ideal force relationships. In a development of the above-described control it is possible for the results of such evaluation to be incorporated into the control of the clip machine, insofar for example with excessively severe wear of the closure tools, a corresponding signal is outputted or the clip machine is stopped.

  • the steps S 302 through S 308 for adjustment for the rest position are effected not after the start of production but after product selection which is effected independently of a start signal.
  • FIG. 2 embodiment In a further configuration (not shown) of the clip machine according to the invention it is possible for the FIG. 2 embodiment to be modified in such a way that the adjusting drive 142 , 144 is omitted and the support mounting 126 is connected directly to the machine housing. Adjustment of the rest position of the punch 110 would then no longer be possible.
  • the force acting on the punch 110 can be measured by means of the piezoelectric sensor 138 at any moment of a closing operation.
  • the control could be modified in such a way that the drive for the punch 110 is switched off when a given value of the closure force is reached and a movement is initiated in the opposite direction.

  • the piezoelectric sensor 138 can also be used as a pure monitoring device which triggers stoppage of the clip machine if the value rises above or falls below a given measurement value range. If it can be ensured that the closure force does not depart from a preset range under normal operating conditions the control of the clip machine according to the invention can be further simplified in that way. As the clip machine is then stopped by the piezoelectric sensor 138 only in emergency situations such as machine damage or wear phenomena and in which repair is to be effected, post-regulation of the closure force by the control 200 can then be entirely omitted.
