Description

Maskinell anordning for formning av en plastisk masse, Mechanical device for forming a plastic mass,

særlig fiskefilet i passende blokkstykker. especially fish fillet in suitable block pieces.

Foreliggende oppfinnelse vedrører en maskinell anordning for formning, fortrinsvis i pak-ningsøyemed, av en plastisk masse, særlig fiskefilet i passende blokkstykker. The present invention relates to a mechanical device for shaping, preferably for packaging purposes, a plastic mass, in particular fish fillets, into suitable block pieces.

Maskinen er av den art som har en kanalformet innretning, hvortil den plastiske masse tilføres, og hvilken kanal er åpen oventil og består av et endeløst underliggende, og to ende-løse sidetransportbånd, som er periodevis, synkronisert bevegelige, og hvilken maskin ennvidere har en med den nevnte åpne kanal fort-løpende lukket kanal, som består av de nevnte tre transportbånd, samt et overliggende, med de øvrige bånd synkronisert, periodevis bevegelig endeløst bånd, som sammen med transportbåndene former og presser massen til en sammenhengende massestreng med ønsket rektangulært tverrsnitt, og mater strengen frem til en knivinnretning, hvis kniv kutter massen i passende stykker i tiden for stillstand mellom de periodevise bevegelser av kanalbåndene, idet ønsket lengde av masseblokkene oppnås ved regulering av den periodevise bevegelseslengde av kanalbåndene. The machine is of the type that has a channel-shaped device, to which the plastic mass is supplied, and which channel is open at the top and consists of an endless underlying, and two endless side conveyor belts, which are periodically, synchronized moving, and which machine further has a with the aforementioned open channel continuously closed channel, which consists of the aforementioned three conveyor belts, as well as an overlying, synchronized with the other belts, periodically moving endless belt, which together with the conveyor belts shapes and presses the mass into a continuous string of mass with the desired rectangular cross-section , and feeds the string forward to a knife device, whose knife cuts the mass into suitable pieces during the period of standstill between the periodic movements of the channel bands, the desired length of the mass blocks being achieved by regulating the periodic movement length of the channel bands.

Formålet med oppfinnelsen er å skaffe en mer enkel og formålstjenlig maskin av den nevnte art enn som hittil er kjent, og dette er oppnådd ved en maskinell anordning, hvis vesentlige nye trekk består i følgende: En med en veivarm forsynt motordrevet drivaksel hvis veivarm på i og for seg kjent måte har en radielt forstillbar og leddbart forbundet stang. Denne stang har i sin annen ende en, med stangen leddbart forbundet — og med en i og for seg kjent fjærende palinnretning forsynt —, veivarm. Ved hjelp av palen beveger denne veivarm et tannhjul periodevis rundt. Tannhjulets aksel har en drivende skive for massekanalens, langs maskinrammen gående, undre transportbånd som i rammens annen ende på vanlig måte er ført over en skive, som i båndets lengderetning fortrinsvis er forstillbar. Den sist nevnte skives aksel overfører driften, på i og for seg kjent måte ved hjelp av koniske tannhjul og kjededrift eller liknende, til skiver for synkronisk drift av massekanalens to sidetransportbånd. Det foran nevnte, med palinnretning forsynte, tannhjul står i inngrep med et tannhjul, hvis aksel ved kjededrift eller liknende overfører driften til en skive, for synkronisk drift av massekanalens lukkete dels øvre bånd, idet massekanalens samtlige bånd på vanlig måte er utstyrt med nødvendige føringshjul, og støtteskinner eller en flerhet av støtteruller for retting av båndene i den åpne — og lukkete kanal. Den ved kanalens utløpsende beliggende kniv, som kutter massen i passende stykker, beveges ved hjelp av et på maskinens drivaksel anordnet drivhjul, som fortrinsvis ved kjededrift og koniske tannhjul overfører driften til knivakselen. The purpose of the invention is to provide a more simple and expedient machine of the aforementioned kind than is known up to now, and this has been achieved by a mechanical arrangement, the essential new features of which consist of the following: A motor-driven drive shaft with a road-warming provided, whose road-warming on i and in a manner known per se has a radially adjustable and articulately connected rod. This rod has, at its other end, a rod, articulated with the rod - and equipped with a known springing paling device -, road warmer. With the help of the pawl, this road heat periodically moves a gear around. The gear shaft has a driving disk for the lower conveyor belt of the mass channel, which runs along the machine frame, and which, at the other end of the frame, is usually guided over a disk, which is preferably adjustable in the longitudinal direction of the belt. The last-mentioned disc's shaft transfers the drive, in a manner known per se by means of conical gears and chain drive or similar, to discs for synchronous operation of the mass channel's two side conveyor belts. The aforesaid gear, provided with a pawl device, meshes with a gear wheel, the shaft of which, by chain drive or the like, transfers the drive to a disc, for synchronous operation of the upper band of the closed part of the mass channel, as all the bands of the mass channel are normally equipped with the necessary guide wheels , and support rails or a plurality of support rollers for straightening the bands in the open and closed channel. The knife located at the outlet end of the channel, which cuts the mass into suitable pieces, is moved by means of a drive wheel arranged on the machine's drive shaft, which, preferably by chain drive and conical gears, transfers the drive to the knife shaft.

Et annet trekk ved oppfinnelsen består i at det på knivakselen, for drift av denne, anordnete koniske tannhjul eller liknende sitter løst på akselen, men trekker denne med rundt under hjulets bevegelser ved hjelp av en til hjulet i aksiell retning festet tapp som har anlegg mot en radiell tapp på knivakselen, som på i og for seg kjent måte er utstyrt med en for en fjær anordnet veivtapp. Fjærens annen ende er forbundet med en fast del på maskinrammen, og slik at fjæren strammes når det koniske tapphjuls tapp ved hjelp av knivakseltappen beveger akselen inntil fjærens veivtapp har nådd sin ytterstilling i forhold til fjærens fastpunkt, fra hvilken stilling fjæren beveger knivakselen hurtig rundt en halv omdreining for kutting av massen fra kanalen, hvorunder knivakseltappen løper fra det koniske tapphjuls tapp, men senere atter innhentes av denne. Another feature of the invention is that the conical gears or the like arranged on the knife shaft, for its operation, sit loosely on the shaft, but pull it around during the movements of the wheel by means of a pin attached to the wheel in the axial direction, which bears against a radial pin on the knife shaft, which is equipped in a manner known per se with a crank pin arranged for a spring. The other end of the spring is connected to a fixed part on the machine frame, and so that the spring is tightened when the pin of the conical pinion wheel, by means of the knife shaft pin, moves the shaft until the spring's crank pin has reached its extreme position in relation to the fixed point of the spring, from which position the spring moves the knife shaft rapidly around a half a turn for cutting the mass from the channel, during which the knife shaft pin runs from the pin of the conical pinion wheel, but is later overtaken by this.

Nok et trekk ved oppfinnelsen består i at knivakselen, for å hindre at knivakselfjæren gir akselen en pendlende bevegelse etter knivens kutting av massen, er utstyrt med en fjærende palanordning som består av en på akselen festet skive, som har tenner på en del av sin omkrets, i forbindelse med en fjærende pal, som hviler mot tannskiven og derved stopper akselens pendelbevegelse. Another feature of the invention is that the knife shaft, in order to prevent the knife shaft spring from giving the shaft a oscillating movement after the knife has cut the mass, is equipped with a spring-loaded pawl device consisting of a disc fixed to the shaft, which has teeth on part of its circumference , in connection with a sprung pawl, which rests against the toothed disc and thereby stops the shaft's pendulum movement.

Andre trekk ved oppfinnelsen vil fremgå av etterfølgende beskrivelse i forbindelse med tegningen, hvor: Fig. 1 viser den maskinelle anordning i oppriss, sett fra siden. Fig. 2 viser anordningen i fig. 1, sett ovenfra i grunnriss, hvor motoren med dens skive for drift av maskinens drivaksel ikke er inntegnet. Fig. 3 viser den maskinelle anordning i fig. 2, sett i oppriss i pilens A retning. Fig. 4 viser den maskinelle anordning i fig. 2, sett i oppriss i pilens B retning. Fig. 5 viser detaljert i større målestokk kniv-innretningen, sett fra siden, med kniven i opp-svingt stilling. Fig. 6 viser detaljert den samme knivihn-retning som i fig. 5, sett ovenfra, med kniven i nedsvingt stilling. Den maskinelle anordning etter oppfinnelsen er oppbygd på en ramme 1 og har en drivaksel 2 som ved remmen 3 på remskiven 4 får overført kraften fra en elektrisk motor 5. Drivakselen 2 er utstyrt med en veivarm 6 som ved tappen 7 er leddbart forbundet med stangen 8. Denne er radielt forstillbar på veivarmen 6 i sporet 9. Stangen 8 er i den annen ende ved bolten 10 leddbart forbundet med veivarmen 11, som er fritt svingbar på akselen 12. Veivarmen 11 beveger et tannhjul 13 på akselen 12 ved hjelp av en på armen anbrakt fjærende palinnretning 14, periodevis rundt, og størrelsen av den periodevise bevegelse er regulerbar ved at stangens 8 tapp 7, som nevnt, er radielt forstillbar på veivarmen 6. Tannhjulsakselen 12 har en drivende skive 15 for massekanalens 16, langs maskinrammen 1 gående, undre transportbånd 17, som fortrinsvis kan være av stål. I rammens annen ende er transportbåndet 17 ført over en til akselen 18 befestiget skive 19. Denne er, for stramning av båndet 17 i rammens 1 lengderetning, forstillbar ved hjelp av stramme-skruene 20 og 21. Akselen 18 overfører driften ved de koniske tannhjul 22 og 23, se fig. 3, til en roterende skive 24 for synkronisk drift av det ene av massekanalens 16 sidetransportbånd 25, som har strammerullen 26 og føringsrullene 27, 28 og 29 samt en flerhet av antydede støtteruller 30 langs båndet for retting av dette i kanalen. Den synkroniske drift av massekanalens 16 annet sidetransportbånds 31 drivende skive 32 skjer fra akslen 18 gjennom de koniske tannhjul 22 og 33 samt kjedehjulet 34, kjeden 35 og kjedehjulet 36 til akselen 37 for skiven. Som for transportbåndet 25, har transportbåndet 31 også en strammerull 38 og føringsruller 39, 40 og 41 samt en flerhet av støtteruller 42 for retting av båndet i kanalen. Det med palinnretning 14 utstyrte tannhjul 13 står i inngrep med et tannhjul 43, hvis aksel 44 ved kjedehjulet 45, kjeden 46 og kjedehjulet 47 overfører driften til en aksel 48 med den drivende skive 49, for synkronisk drift av massekanalens 16 lukkete dels øvre bånd 50, som i den lukkete kanals annen ende løper over et føringshjul 51, og er utstyrt med strammerullen 52. Hjulet 51 er anbrakt i en om aksen 48 i pilens 53 retning svingbar ramme 54, som har de roterbare støtteruller 55 for retting av pressbåndet 50 ved massens gjenr nomføring i kanalen. Den nevnte oppsvingning av båndet 50 i pilens 53 retning foretas for kanalens rengjøring. Ved kanalens utløpsende, — som i bunnen i flukt med det undre bånds 17 horisontale del har en bunnplate 56 —, er en knivinnretning med den på knivakselen 57 svingbare kniv 58. Denne beveges, som foran nevnt, i tiden for stillstand mellom de periodevise bevegelser av kanalbåndene, for kutting av massen i porsjoner. Knivakselen 57 får sin drift fra drivakselen 2 gjennom kjedehjulet 59, kjeden 60, kjedehjulet 61 og de koniske tannhjul 62 samt 63. Tannhjulet 63 sitter løst på akselen 57, og drar denne med under hjulets' bevegelser ved hjelp av en til hjulet i aksiell retning festet tapp 64 i anlegg mot en radiell tapp 65 på knivakselen 57. Denne er utstyrt med en for en fjær fjær 66 anordnet veivtapp 67, hvor fjærens annen ende er forbundet med en fastdel 11 på maskinrammen 1, som det fremgår av figurene 5 og 6. Anordningen er slik at fjæren 66 strammes når tappen 64, ved hjelp av knivakseltappen, beveger akselen 57 inntil fjærens veivtapp 67 har nådd sin ytterstilling i forhold til fjærens fastpunkt. Fra denne stilling beveger fjæren 66 knivakselen 57 hurtig rundt en halv omdreining i pilens 68 retning, for kutting av massen fra kanalen 16, hvorunder knivakseltappen 65 løper fra tannhjulstappen 64, men senere atter innhentes av denne. For å hindre at knivakselfjæren 66 gir akselen 57 en pendlende bevegelse etter knivens kutting av massen, er knivakselen utstyrt med en fjærende palanordning. Denne består av en på akselen anordnet skive 69, som er forsynt med tenner på en del av sin omkrets, samt en mot skiven hvilende, fjærende pal 70, som stopper akselens pendelbevegelse. Tannhjulet 13, se fig. 1, er også utstyrt med en fjærende palinnretning 71 for å hindre at det dras med palen 14 tilbake etter en periodevis bevegelse i pilens 72 retning. Other features of the invention will be apparent from the following description in connection with the drawing, where: Fig. 1 shows the mechanical device in elevation, seen from the side. Fig. 2 shows the device in fig. 1, seen from above in ground plan, where the motor with its disk for operating the machine's drive shaft is not drawn. Fig. 3 shows the mechanical device in fig. 2, seen in elevation in the direction of arrow A. Fig. 4 shows the mechanical device in fig. 2, seen in elevation in the direction of arrow B. Fig. 5 shows the knife device in detail on a larger scale, seen from the side, with the knife in an upturned position. Fig. 6 shows in detail the same knivihn direction as in fig. 5, seen from above, with the knife in the downswing position. The mechanical device according to the invention is built on a frame 1 and has a drive shaft 2 which, by means of the belt 3 on the pulley 4, transmits the power from an electric motor 5. The drive shaft 2 is equipped with a crank 6 which, at the pin 7, is articulately connected to the rod 8 This can be radially adjusted on the crank arm 6 in the groove 9. The rod 8 is at the other end at the bolt 10 articulatedly connected to the crank arm 11, which is freely pivotable on the shaft 12. The crank arm 11 moves a gear 13 on the shaft 12 by means of a The arm is fitted with a sprung pawl device 14, periodically around, and the size of the periodic movement is adjustable by the rod 8 pin 7, as mentioned, being radially adjustable on the crank 6. The gear shaft 12 has a driving disk 15 for the mass channel 16, running along the machine frame 1, lower conveyor belt 17, which can preferably be made of steel. At the other end of the frame, the conveyor belt 17 is guided over a disk 19 attached to the shaft 18. This can be adjusted, for tightening the belt 17 in the longitudinal direction of the frame 1, by means of the tightening screws 20 and 21. The shaft 18 transmits the operation by the conical gears 22 and 23, see fig. 3, to a rotating disc 24 for synchronous operation of one of the pulp channel 16 side conveyor belts 25, which has the tension roller 26 and guide rollers 27, 28 and 29 as well as a plurality of indicated support rollers 30 along the belt for straightening this in the channel. It synchronous operation of the mass channel 16's other side conveyor belt 31's driving disk 32 takes place from the shaft 18 through the bevel gears 22 and 33 as well as the sprocket 34, the chain 35 and the sprocket 36 to the shaft 37 for the disk. As for the conveyor belt 25, the conveyor belt 31 also has a tension roller 38 and guide rollers 39, 40 and 41 as well as a plurality of support rollers 42 for straightening the belt in the channel. The pinion device 14-equipped gear 13 meshes with a gear 43, whose axle 44 at the sprocket 45, the chain 46 and the sprocket 47 transfers the operation to an axle 48 with the driving disc 49, for synchronous operation of the upper band 50 of the mass channel 16, which is closed , which at the other end of the closed channel runs over a guide wheel 51, and is equipped with the tension roller 52. The wheel 51 is placed in a frame 54 which can be pivoted about the axis 48 in the direction of the arrow 53, which has the rotatable support rollers 55 for straightening the press belt 50 by the transfer of the mass in the channel. The aforementioned swinging of the belt 50 in the direction of the arrow 53 is carried out for cleaning the channel. At the outlet end of the channel, — which has a bottom plate 56 at the bottom flush with the horizontal part of the lower band 17 —, is a knife device with the knife 58 pivotable on the knife shaft 57. This is moved, as mentioned above, during the period of standstill between the periodic movements of the duct tapes, for cutting the mass into portions. The blade shaft 57 receives its operation from the drive shaft 2 through the sprocket 59, the chain 60, the sprocket 61 and the conical gears 62 and 63. The sprocket 63 is loosely attached to the shaft 57, and pulls it along during the wheel's movements with the help of a to the wheel in the axial direction fixed pin 64 in abutment against a radial pin 65 on the knife shaft 57. This is equipped with a crank pin 67 arranged for a spring spring 66, where the other end of the spring is connected to a fixed part 11 on the machine frame 1, as can be seen from figures 5 and 6 The device is such that the spring 66 is tightened when the pin 64, by means of the knife shaft pin, moves the shaft 57 until the spring's crank pin 67 has reached its extreme position in relation to the spring's fixed point. From this position, the spring 66 moves the knife shaft 57 quickly around half a turn in the direction of the arrow 68, for cutting the mass from the channel 16, under which the knife shaft pin 65 runs from the gear pin 64, but is later caught up by this. In order to prevent the knife shaft spring 66 from giving the shaft 57 a oscillating movement after the knife has cut the mass, the knife shaft is equipped with a spring-loaded pawl device. This consists of a disk 69 arranged on the shaft, which is provided with teeth on part of its circumference, as well as a spring-loaded pawl 70 resting against the disk, which stops the pendulum movement of the shaft. The toothed wheel 13, see fig. 1, is also equipped with a spring-loaded pawl device 71 to prevent the pawl 14 from being pulled back after a periodic movement in the direction of the arrow 72.
