Description

Die Erfindung betrifft eine Papiervorschubeinrichtung für eine Maschine zum Schneiden von Schneidgutriegeln, wie Käse- und Wurstriegel oder dergleichen, mit einer den Schneidgutriegel abstützenden und intermittierend jeweils um die Dicke der abgeschnittenen Scheiben voranbewegenden Transporteinrichtung, die aus einem den Schneidgutriegel abstützenden Förderband und einer diesen haltenden Einrichtung besteht, und mit einem vor dem vorderen Ende des Förderbandes angeordneten Kreismesser, das mit einem dieses in Querrichtung verschiebenden Antrieb versehen ist.The invention relates to a paper feed device for a machine for cutting cuttings bars, such as cheese and sausage bars or the like, with a transport device supporting the cuttings bar and moving intermittently by the thickness of the cut slices, which consists of a conveyor belt supporting the cuttings bar and a device holding the same exists, and with a circular knife arranged in front of the front end of the conveyor belt, which is provided with a drive which moves it in the transverse direction.

Beim Stapeln der von dem Schneidgutriegel abgetrennten Scheiben ist es wünschenswert, zwischen die einzelnen Scheiben des Stapels Papierzettel zu legen, die ein Verkleben der einzelnen Scheiben miteinander verhindern und beim Gebrauch das Entnehmen der einzelnen Scheiben von dem Stapel erleichtern.When stacking the slices separated from the product bar, it is desirable to place paper slips between the individual slices of the stack, which prevent the individual slices from sticking to one another and facilitate the removal of the individual slices from the stack during use.

Aufgabe der Erfindung ist es daher, eine Papiervorschubeinrichtung der eingangs angegebenen Art zu schaffen, die in einfacher Weise das Einschieben von Trennzetteln zwischen die einzelnen gestapelten Erfindungsgemäß wird diese Aufgabe bei einer Papiervorschubeinrichtung der gattungsgemäßen Art dadurch gelöst, daß unterhalb des Förderbandes ein intermittierend angetriebenes Vorzugswalzenpaar für eine von einer Vorratsrolle abgezogene Papierbahn angeordnet ist, deren Vorschubbahn im Bereich der unteren Kante der Vorderseite des auf dem Förderband liegenden Schneidgutriegels liegt. Bei der neuerungsgemäßen Vorrichtung ist die Papiervorschubeinrichtung unterhalb des Förderbandes angeordnet, deren im wesentlichen horizontale Vorschubebene im Bereich der Unterkante des in seiner Schnittstellung befindlichen Schnittgutriegels liegt und die intermittierend das vordere freie Ende der Papierbahn um jeweils etwa eine Scheibenbreite über die zuletzt geschnittene Scheibe schiebt. Das jeweils vordere Ende der Papierbahn befindet sich im Bereich der unterem vorderen Kante des Schnittgutriegels, so daß gleichzeitig mit dem Schneiden der Schnittgutscheiben auch die dem späteren besseren Trennen der Scheiben dienenden Zettel von der Papierbahn abgetrennt werden.The object of the invention is therefore to provide a paper feed device of the type specified at the outset, which in a simple manner inserts stacking slips between the individual ones According to the invention, this object is achieved in a paper feed device of the generic type in that an intermittently driven pair of feed rollers is arranged below the conveyor belt for a paper web drawn off from a supply roll, the feed path of which lies in the region of the lower edge of the front of the cutting bar lying on the conveyor belt. In the device according to the innovation, the paper feed device is arranged below the conveyor belt, the substantially horizontal feed plane of which lies in the area of the lower edge of the cut bar in its cutting position and which intermittently pushes the front free end of the paper web about one slice width each over the last cut slice. The respective front end of the paper web is located in the area of the lower front edge of the clippings bar, so that at the same time as the slices of clippings are cut, the slips which later serve to separate the slices are also separated from the paper web.

Eine saubere Lage der abgetrennten Zettel wird dadurch begünstigt, daß eine das vordere vorgeschobene Ende der Papierbahn gegen die Schnittfläche des Riegels blasende Blasluftdüse vorgesehen ist.A clean position of the separated pieces of paper is favored by the fact that a blowing air nozzle blowing the front forward end of the paper web against the cut surface of the bar is provided.

Um eine sichere Halterung des Schnittgutriegels während des Schneidens sicherzustellen, kann im Bereich oberhalb der unteren Umlenkrolle des Förderbandes eine auf den Schnittgutriegel absenkbare Andrückwalze vorgesehen sein.In order to ensure that the cut goods bar is held securely during cutting, a pressure roller which can be lowered onto the cut goods bar can be provided in the region above the lower deflection roller of the conveyor belt.

In erfinderischer Weiterbildung ist vorgesehen, daß die die Papierbahn vorziehende Walze oder Walzen von einem Getriebe angetrieben sind, das ein Ausgleichsgetriebe einschließt, dessen dritter Eingang im Schnoidtakt von einem Kurbeltrieb durch eine Plouolstange hin- und hergedreht wird. Der Hub des Kurbeltriebs kann derart ausgelegt werden, daß nach dem Vorschub der Papierbahn und Abtrennen des Zettels die Papierbahn ein wenig zurückgezogen wird, was das erneute störungsfreie Vorschieben begünstigt. Zweckmäßigerweise ist das Ausgleichsgetriebe ein Kegelradausgleichsgetriebe, dessen die Ausgleichskegelräder lagerndes Gehäuse von dem Kurbeltrieb hin- und hergedreht wird.In a further development according to the invention it is provided that the roll or rolls which advance the paper web are driven by a gear which includes a differential gear, the third input is rotated back and forth by a crank mechanism through a Plouol rod. The stroke of the crank mechanism can be designed in such a way that after the paper web has been fed and the slip separated, the paper web is pulled back a little, which favors the trouble-free advancement again. The differential is expediently a bevel gear differential, the housing of which the differential bevel gears are mounted is rotated back and forth by the crank mechanism.

The support strips 17, 18, 17 ', 18' are driven back and forth by drive means, not shown. The gripping claw shafts also have these reciprocating drives and additional swivel drives, which consist of pneumatic pressure-piston-cylinder units.

An den äußeren Endbereichen der Tragstücke 15, 15' sind Spindelmuttern 22 befestigt, in die die Spindeln 7, 8 eingeschraubt sind. Beidseits des Förderbandes sind parallel zu den Spindeln 7, 8 verlaufende Schienen 23, 24 angeordnet, auf denen die Tragstücke 15, 15' gleitend abgestützt sind.Spindle nuts 22, into which the spindles 7, 8 are screwed, are fastened to the outer end regions of the support pieces 15, 15 '. On both sides of the conveyor belt, rails 23, 24 are arranged parallel to the spindles 7, 8, on which the support pieces 15, 15 'are slidably supported.

Hinter der oberen Umlenkwalze 10 des Förderbandes 11 ist um eine im Gestell befestigte Achse 25 eine Röllchenbahn 26 schwenkbar gelagert, die an ihrem vorderen Ende mit einem ein-und ausschwenkbaren Anschlag 27 versehen ist. Im Abstand von der Schwenkachse 25 ist. die Röllchenbahn 26 an die Kolbenstange eines Pneumatikzylinders 28 angelenkt, der gelenkig im Maschinengestell gelagert ist. Zum Einschwenken und Ausschwenken der Anschlagplatte 27 ist die Röllchenbahn 26 mit einem weiteren Pneumatikzylinder 29 versehen.Behind the upper deflection roller 10 of the conveyor belt 11, a roller track 26 is pivotally mounted about an axis 25 fastened in the frame and is provided at its front end with a stop 27 which can be swiveled in and out. Is at a distance from the pivot axis 25. the roller track 26 is articulated to the piston rod of a pneumatic cylinder 28 which is articulated in the machine frame. The roller track 26 is provided with a further pneumatic cylinder 29 for pivoting in and pivoting out the stop plate 27.

Wie in Fig. 4 dargestellt ist, weisen die Tragstücke 15, 15' auf ihrer dem Förderband 11 zugewandten Seite eine schwenkbare Klemmbacke 30 auf, die mit einem Widerlager 31 der Tragstücke zusammenwirkt. Sobald die Tragstücke 15, 15' in den Bereich des Förderbandes 11 gefahren worden sind, werden diese durch Schließen der Klemmbacke 30 durch einen nicht dargestellten Pneumatikzylinder reibschlüssig an das Obertrum des Förderbandes 11 angekuppelt.As shown in FIG. 4, the support pieces 15, 15 'have on their side facing the conveyor belt 11 a pivotable clamping jaw 30 which cooperates with an abutment 31 of the support pieces. As soon as the support pieces 15, 15 'have been moved into the area of the conveyor belt 11, they are frictionally coupled to the upper run of the conveyor belt 11 by closing the clamping jaw 30 by means of a pneumatic cylinder (not shown).

Unterhalb des Arbeitsbereiches des rotierenden und durch einen Exzenter über den Schnittbereich geführten Kreismessers 32 ist eine aus im Abstand parallel zueinander umlaufenden endlosen Riemen bestehende Fördereinrichtung 33 angeordnet. Weiterhin sind zwei durch einen nicht dargestellten Mechanismus bewegte Roste 34, 35 mit frei auskragenden Zinken 36 vorgesehen, die parallel zu sich selbst unter den Arbeitsbereich des Kreismessers oberhalb der Fördereinrichtung 33 im Wechsel einfahrbar und mit ihren Zinken in die Zwischenräume zwischen die endlosen Riemen 38 der Fördereinrichtung 33 absenkbar sind. Die Roste 34, 35 dienen der Bildung von Stapeln aus den geschnittenen Scheiben und sind entsprechend der zunehmenden Stapelhöhe absenkbar. Zum Abfördern der Stapel werden die Scheibenpakete auf die endlosen Riemen 38 der Fördereinrichtung 33 abgesetzt. Während des Abtransports des letzten Stapels kann bereits der andere Rost über diesen eingefahren werden, so daß durch die Abförderung der Stapel keine Unterbrechung in dem Schneidbetrieb eintritt.Below the working area of the rotating circular knife 32, which is guided by an eccentric over the cutting area a conveyor device 33 consisting of endless belts running at a distance parallel to one another is arranged. Furthermore, two gratings 34, 35, which are moved by a mechanism (not shown) and have freely projecting tines 36, are provided, which can be moved in parallel parallel to themselves under the working area of the circular knife above the conveyor device 33 and with their tines into the spaces between the endless belts 38 Conveyor 33 can be lowered. The gratings 3 4 , 35 serve to form stacks from the cut slices and can be lowered in accordance with the increasing stack height. To remove the stacks, the disk packs are placed on the endless belts 38 of the conveyor 33. During the removal of the last stack, the other grate can already be retracted over it, so that the stacking does not interrupt the cutting operation.

Wie aus Fig. 6 ersichtlich ist, ist eine aus Walzen bestehende Vorzugseinrichtung für eine von einer Vorratsrolle 39 abgezogene Papierbahn 40 vorgesehen, die intermittierend um etwa jeweils eine Scheibenbreite über die zuletzt geschnittene Scheibe 41 vorgeschoben wird. Die Papierbahn 40 wird durch wippenartig angeordnete Rollenpaare, die mit Gegenwalzen zusammenwirken, vorgezogen, wie sie ihrem grundsätzlichen Aufbau nach aus der DE-OS 22 52 605 bekannt sind. Die etwa waagerechte Vorschubebene der Papierbahn berührt den zu schneidenden Schnittgutriegel 42 an seinem unteren Kantenbereich, so daß von der Papierbahn zusammen mit der Scheibe ein Zettel 43 abgetrennt wird und zusammen mit der abgeschnittenen Scheibe auf den Stapel 44 fällt.As can be seen from FIG. 6, a preferred device consisting of rollers is provided for a paper web 40 drawn off from a supply roll 39, which is intermittently advanced by approximately one slice width over the last cut slice 41. The paper web 40 is preferred by pairs of rollers arranged in the manner of a rocker, which interact with counter-rollers, as are known in their basic structure from DE-OS 22 52 605. The approximately horizontal feed plane of the paper web touches the cut goods bar 42 to be cut at its lower edge region, so that a piece of paper 43 is separated from the paper web together with the disk and falls onto the stack 44 together with the cut disk.

Unterhalb des vorderen Endes der vorgeschobenen Papierbahn 40 ist eine nicht dargestellte Blasdüse angeordnet, die das vordere Ende der Papierbahn in der aus Fig. 3 ersichtlichen Weise gegen die vordere Schnittfläche der zuletzt getrennten Scheibe andrückt.Below the front end of the advanced paper web 40 is a blowing nozzle, not shown, which is the front 3 presses against the front cut surface of the last separated disc in the manner shown in FIG.

Die Vorschubeinrichtung für die Papierbahn 40 besteht aus je zwei in einer Wippe 45, 46 frei drehbar gelagerten Walzen 47,48 und 49, 50, die jeweils mit Gegenwalzen zusammenwirken, von denen die Walzen 51, 52 angetrieben sind.The feed device for the paper web 40 consists of two rollers 47, 48 and 49, 50 which are freely rotatably mounted in a rocker 45, 46 and which each cooperate with counter-rollers, by which the rollers 51, 52 are driven.

Die Vorzugseinrichtung mit der Wippe 46 dient der Bildung einer Vorratsschlaufe in der Papierbahn 40, die von der federbelasteten Pendelwalze 53 ausgezogen wird. Aus dieser Vorratsschlaufe zieht sodann die angetriebene Walze 51 nach Absenken der Andruckwalze 48 intermittierend die Bahn um jeweils eine Zettelbreite vor. Das Verschwenken der die Walzen tragenden Wippen erfolgt in der aus der DE-OS 22 52 605 bekannten Weise durch Pneumatikzylinder.The preferred device with the rocker 46 is used to form a supply loop in the paper web 40, which is pulled out by the spring-loaded pendulum roller 53. From this supply loop, the driven roller 51 then intermittently pulls the web forward by one slip width after lowering the pressure roller 48. The pivoting of the rockers carrying the rollers is carried out in the manner known from DE-OS 22 52 605 by pneumatic cylinders.

Das die Vorzugswalze 51 antreibende Getriebe wird nachstehend anhand der Fig. 7 näher erläutert. Die Antriebswelle 54 treibt über Stirnradpaarungen die parallel zu dieser angeordneten Wellen 55, 56 an. Die Welle 55 bildet die Eingangswelle des Kebelradausgleichsgetriebes 57, dessen mit dieser fluchtende Abtriebswelle 58 mit der Papiervorschubswalze 51 in Antriebsverbindung steht. Das Kegelradausgleichsgetriebe 57 weist ein Übersetzungsverhältnis i = 1:1 auf.The transmission driving the preferred roller 51 is explained in more detail below with reference to FIG. 7. The drive shaft 54 drives the shafts 55, 56 arranged parallel to the spur gear pairs. The shaft 55 forms the input shaft of the bevel gear differential 57, the output shaft 58 of which is in alignment with this and is in drive connection with the paper feed roller 51. The bevel gear differential 57 has a gear ratio i = 1: 1.

Die Welle 56 ist mit einem exzentrischen Kurbelzapfen 59 versehen, auf dem die Pleuelstange 60 gelagert ist, die an den Käfig 61 des Kegelradausgleichsgetriebes 57 angelenkt ist und diesen in eine pendelnd hin- und hergehende Bewegung versetzt. Diese Pendelbewegung entspricht aufgrund der gewählten Ubersetzungen dem Maschinentakt und'weist eine Amplitude auf, die dem gewünschten intermittierenden Vorschub der Papierbahn entspricht.The shaft 56 is provided with an eccentric crank pin 59, on which the connecting rod 60 is mounted, which is articulated on the cage 61 of the bevel gear differential gear 57 and sets it in an oscillating reciprocating motion. Due to the selected gear ratios, this pendulum movement corresponds to the machine cycle and has an amplitude that corresponds to the desired intermittent feed of the paper web.

Wird kein Papiervorschub gewünscht, wird die Andruckrolle 48 von der Vorzugswalze 51 abgehoben und die Papierbahn durch die Walze 47 festgeklemmt.If no paper feed is desired, the pressure roller 48 is lifted off the feed roller 51 and the paper web is clamped by the roller 47.

Das Getriebe für den intermittierenden Vorschubantrieb der Spindeln 7, 8 wird nachstehend anhand der Fig. 8 näher erläutert. Auf der Antriebswelle 62 sind exzentrisch zwei Kugellager 63, 64 aufgekeilt, die zusammen mit den Pleuelstangen 65, 66 jeweils Kurbeltriebe bilden. Die zu der Antriebswelle 62 parallele Abtriebswelle 77, die mit den Spindeln 7, 8 in Antriebsverbindung steht, ist mit einer Kupplungsbremskombination 78 versehen.The gear for the intermittent feed drive of the spindles 7, 8 is explained in more detail below with reference to FIG. 8. Eccentrically, two ball bearings 63, 64 are wedged on the drive shaft 62, which together with the connecting rods 65, 66 each form crank drives. The output shaft 77 parallel to the drive shaft 62, which is in drive connection with the spindles 7, 8, is provided with a clutch / brake combination 78.

Die Kupplungsbremskombination 78 weist einen Kupplungsteller 79 auf, der mit einer innenkonusförmigen Kupplungsfläche versehen und mit der Abtriebswelle 57 drehschlüssig verbunden ist. Relativ zu der Abtriebswelle 57 ist der Kupplungsteller 78 auf axialen Mitnehmerbolzen 80 axialverschieblich geführt und durch Druckfedern 81 belastet. In der.Bremsstellung drücken die Druckfedern 81 den Kupplungsteller 79 mit seinem konusförmigen äußeren Ring gegen den gehäusefesten innenkonusförmigen Bremsring 82.The clutch / brake combination 78 has a clutch actuator 79, which is provided with an internally conical clutch surface and is connected to the output shaft 57 in a rotationally locking manner. Relative to the output shaft 57, the clutch actuator 78 is axially displaceably guided on the axial driving pins 80 and is loaded by compression springs 81. In the braking position, the compression springs 81 press the clutch actuator 79 with its conical outer ring against the inner conical brake ring 82.

Das Pleuel 66 treibt über den exzentrischen Bolzen 83 die Antriebshülse 84, die drehbar auf der Abtriebswelle 77 gelagert ist, hin- und hergehend pendelnd an. Die Antriebshülse 84 ist mit axial verlaufenden Bolzen 85 versehen, auf denen die Kupplungshülse 86 axial verschieblich geführt ist. Die Kupplungshülse 86 ist frei drehbar, aber axial unverschieblich mit der Schalthülse 87 verbunden. Die Schalthülse 87 ist in ein dreigängiges Trapezgewinde 88 der Steuerhülse 89 eingeschraubt, die über Nadellager frei drehbar, aber axial unverschieblich auf der Antriebshülse 84 gelagert ist. Die Steuerhülse 89 ist mit einem exzentrischen Bolzen 90 versehen, auf dem die Pleuelstange 65 gelagert ist. Durch den Kurbeltrieb 63, 65 wird somit die Steuerhülse 89 im Maschinentakt in eine pendelnde Bewegung versetzt, so daß im Maschinentakt der Kupplungsteller 79 von der Kupplungshülse 86 von dem Bremsring 82 abgehoben und an die Antriebshülse 84 angekuppelt wird.The connecting rod 66 drives the drive sleeve 84, which is rotatably mounted on the output shaft 77, to oscillate back and forth via the eccentric bolt 83. The drive sleeve 84 is provided with axially extending bolts 85, on which the coupling sleeve 86 is axially displaceably guided. The coupling sleeve 86 is freely rotatable, but axially immovably connected to the switching sleeve 87. The switching sleeve 87 is in a three common trapezoidal thread 88 of the control sleeve 89 is screwed in, which is freely rotatable via the needle bearing, but is axially immovable on the drive sleeve 84. The control sleeve 89 is provided with an eccentric pin 90 on which the connecting rod 65 is mounted. By means of the crank mechanism 63, 65, the control sleeve 89 is thus set in an oscillating movement in the machine cycle, so that the clutch actuator 79 is lifted from the clutch sleeve 86 by the brake ring 82 in the machine cycle and is coupled to the drive sleeve 84.

Entsprechend der jeweils gewünschten intermittierenden Vorschubbewegung ist der Hub des Kurbeltriebes 64, 66 veränderbar. Zu diesem Zwecke ist auf die Antriebswelle 62 das Sonnenrad 92 eines Planetenräder-Umlaufgetriebes 91 aufgekeilt, das bei stillstehendem Planetenrädersteg 94 die Antriebsdrehzahl auf die Ausgangshülse 93, die über Nadellager auf der Antriebswelle 62 gelagert ist, überträgt, so daß die Antriebswelle 62 und die Ausgangshülse 93 mit gleicher Drehzahl rotieren. Auf die Ausgangshülse 93 ist ein Rad 95 mit stirnseitiger spiralförmiger Trapezverzahnung aufgekeilt. Mit der Trapezverzahnung kämmt ein verzahnter Block 96, der mit dem das Kugellager 64 tragenden Ring fest verbunden ist und in einer radialen Führung 97 der Scheibe 98 geführt ist, die auf die Antriebswelle 62 aufgekeilt ist. Über einen Schneckenradtrieb 99 ist eine zusätzliche Drehbewegung in den Planetenrädersteg 94 des Planetenräderumlaufgetriebes 91 einspeisbar, so daß zur Verstellung der Exzentrizität des Kurbeltriebes 64, 66 die Scheibe 64 verdrehbar ist.The stroke of the crank mechanism 64, 66 can be changed in accordance with the desired intermittent feed movement. For this purpose, the sun gear 92 of a planetary planetary gear 91 is keyed onto the drive shaft 62, which transmits the drive speed to the output sleeve 93, which is supported on the drive shaft 62 via needle bearings, when the planet gear web 94 is at rest, so that the drive shaft 62 and the output sleeve 93 rotate at the same speed. A wheel 95 with helical trapezoidal toothing on the face is wedged onto the output sleeve 93. The trapezoidal toothing meshes with a toothed block 96 which is fixedly connected to the ring carrying the ball bearing 64 and is guided in a radial guide 97 of the disk 98 which is wedged onto the drive shaft 62. An additional rotary movement can be fed into the planet gear web 94 of the planetary planetary gear train 91 via a worm gear drive 99, so that the disk 64 can be rotated to adjust the eccentricity of the crank drive 64, 66.

Das intermittierende Vorschubgetriebe für die Spindeln 7, 8 ist so ausgelegt, daß über die Kupplungsbremskombination 78 je Umdrehung des Kurbeltriebes 64, 66 eine Rotationsbewegung von 25% mit ansteigender sinusförmiger Beschleunigung, 25% abfallender sinusförmiger Verzögerung und anschließendem 50%igem Stillstand übertragen wird.The intermittent feed gear for the spindles 7, 8 is designed such that a rotation movement of 25% with increasing sinusoidal acceleration, 25% falling sinusoidal deceleration and subsequent 50% standstill is transmitted via the clutch brake combination 78 per revolution of the crank mechanism 64, 66.
