Opfindelsen angår et apparat til aftagning af snore fra halmballer, navnlig hovedsageligt kasseformede storballer, i hvilke halmen er sammenholdt af snore, som er ført omkring halmballen i snorplaner, der er ho-5 vedsageligt parallelle indbyrdes og med et første par modstående sideflader af halmballen.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to an apparatus for removing straw bales, in particular mainly box-shaped large bales, in which the straw is joined by strings passed around the straw bales in string planes which are substantially parallel to one another and with a first pair of opposite side faces of the straw bales.

Med den tiltagende brug af overskudshalm presset sammen i baller til en række forskellige anvendelsesformål, herunder som strøelse til foderbrug og til 10 halmfyring, tager opfindelsen sigte på at anvise et forholdsvis enkelt apparat, som i væsentligt omfang letter den tidrøvende manuelle fjernelse af de snore, som på den ovennævnte måde er viklet omkring ballerne.With the increasing use of surplus straw compressed into bales for a variety of uses, including as bedding for feed and for straw firing, the invention aims to provide a relatively simple apparatus which substantially facilitates the time-consuming manual removal of the cords. which in the above manner is wrapped around the balls.

En sådan maskinel snoraftagning er i forbindelse 15 med baller af affaldspapir og tørt pulpmateriale i og for sig kendt fra US patentskrift nr. 4 841 619. Snoraftagnings- og opviklingsmekanismen er ved denne kendte maskine ophængt for enden af en bom som i sin modsatte ende bæres af en parallellogramunderstøtning der er 20 forbundet med en drejeskive, der er monteret med stationær lodret akse på en fast understøtning ved siden af en balletransportør.Such machine cord removal is in connection with bales of waste paper and dry pulp material known per se from US Patent No. 4,841,619. The cord removal and winding mechanism is suspended at this known machine by the end of a boom which is carried at its opposite end. of a parallelogram support 20 connected to a turntable mounted with stationary vertical axis on a fixed support adjacent to a bale conveyor.

Selve snoraftagningsmekanismen med skæreindretningen og aftageindretningen danner således ved den 25 kendte maskine en samlet enhed en forholdsvis kompliceret mekanisk opbygning og et tilsvarende kompliceret bevægelsesmønster henover den balle, hvorfra snoren ønskes fj ernet.Thus, the string removal mechanism itself with the cutting device and the removal device forms, by the known machine, a total unit a relatively complicated mechanical structure and a correspondingly complicated pattern of movement across the bale from which the string is desired to be removed.

I forhold hertil tilsigtes det ved opfindelsen 30 at anvise en enklere og mere robust udformning som er velegnet til brug på landbrugsbedrifter.In relation to this, the invention 30 aims to provide a simpler and more robust design suitable for use on agricultural holdings.

Med henblik herpå er apparatet ifølge opfindelsen ejendommeligt ved, at der i forbindelse med en understøtningsflade for halmballen og en i forhold til 35 understøtningsfladen stationær bærekonstruktion findes et skæreorgan og en med et fangorgan forsynet snorafta- DK 169739 B1 2 geindretning anbragt ved hver sin af et andet par modstående sideflader af halmballen samt midler til frembringelse af relativ bevægelse mellem halmballen og henholdsvis nævnte skæreorgan og nævnte snoraftagein-5 dretning' på tværs af snorplanerne til overskæring af snorene i samtlige snorplaner ved den ene og efterfølgende aftagning af snorene ved den anden af nævnte andet par modstående sideflader.To this end, the apparatus according to the invention is characterized in that in connection with a support surface for the straw bale and a stationary support structure relative to the support surface, a cutting means and a lacing rope arrangement are provided at each of a second pair of opposite side faces of the straw bale and means for generating relative movement between the straw bale and said cutting means and said string removal device, respectively, across the string planes for cutting the cords in all the string planes by one and subsequent removal of the cords at the other of said second pair of facing side surfaces.

Ved hjælp af apparatet ifølge opfindelsen opnås 10 en problemfri maskinel fjernelse af de omviklede snore, så halmen i halmballen er umiddelbar tilgængelig for den tilsigtede anvendelse. I forbindelse med sønderdelings- eller oprivningsapparater af den art, der fx finder anvendelse til halmopskæring forud for indføring 15 i halmfyr, fjernes hermed også risikoen for driftstop som følge af mangelfuld snoroverskæring.By means of the apparatus according to the invention, 10 provides a trouble-free machine removal of the wrapped cords, so that the straw in the straw bale is readily available for the intended use. In connection with disintegrating or tearing devices of the kind that are used, for example, for straw cutting prior to introduction 15 into straw fires, the risk of downtime due to inadequate string cutting is also removed.

ved en foretrukket udførelsesform for apparatet ifølge opfindelsen er skæreorganet anbragt i en spalte i understøtningsfladen til overskæring af snorene ved 20 en mod understøtningsfladen liggende underside af en halmballe og snoraftageindretningen er lejret i nævnte bærekonstruktion til udførelse af en hovedsageligt lineær snoraftagebevægelse henover halmballens modsat liggende overside fra den ene til den anden af nævnte 25 første par modstående sideflader, hvorhos der findes midler til efterfølgende tilbageføring af snoraftageindretningen til en udgangsstilling ved nævnte ene sideflade.in a preferred embodiment of the apparatus according to the invention, the cutting means is arranged in a slot in the support surface for cutting the cords at a underside of a straw bale against the support surface and the cord removal device is mounted in said support structure for carrying out a substantially linear cantilever wall cutting edge surface. one to the other of said first 25 pairs of opposite side surfaces, wherein means for subsequently returning the cord removal device to a starting position at said one side surface are provided.

ved en foretrukken udførelsesform omfatter snor-30 aftageindretningen en snoropvikletromle, som er lejret i bærekonstruktionen til i fortsættelse af nævnte snoraftagebevægelse i en slutstilling ved den anden af nævnte første par modstående sideflader at udføre en roterende bevægelse til opvikling af de aftagne snore, 35 og at der i tilknytning til bærekonstruktionen ved den anden af nævnte par første par modstående sideflader 3 DK 169739 B1 findes midler til aftagning af de opviklede snore fra tromlen.in a preferred embodiment, the cord removal device comprises a cord winding drum which is mounted in the carrier structure to carry out a rotary motion to wind up the detached cords in a final position at the second of said first pair of opposite side surfaces. means are provided for removing the wound cords from the drum in connection with the support structure at the second of said pair of first pair of opposite side surfaces 3 DK 169739 B1.

Opfindelsen forklares i det følgende nærmere under henvisning til den skematiske tegning, hvor 5 fig. 1, 2 og 3 viser en udførelsesform for et snoraftagningsapparat ifølge opfindelsen set henholdsvis fra siden, fra oven og fra den ene ende.The invention will now be explained in more detail with reference to the schematic drawing, in which: FIG. Figures 1, 2 and 3 show an embodiment of a cord removal apparatus according to the invention viewed from the side, from above and from one end respectively.

Det i fig. 1-3 viste apparat er beregnet til aftagning af snore fra en kasseformet storballe 1, fx af 10 den såkaldte Heston type, hvor snorene 2 er viklet om ballen 1 i snorplaner, der er hovedsageligt parallelle indbyrdes og med et første par modstående sideflader 3 og 4 af halmballen. Apparatet omfatter en understøtningsflade 5, fx et bord, mod hvilken halmballen 15 1's underside 6 er i anlæg. I en slids 7 i understøtningsfladen 5 er et i den viste udførelsesform roterende skæreorgan 8 lejret til frem- og tilbagegående bevægelse i en retning vinkelret på snorplanerne mellem sidefladerne 3 og 4 med henblik på overskæ-20 ring af snorene i samtlige snorplaner.The FIG. 1-3 is intended for removing cords from a box-shaped large bale 1, for example of the so-called Heston type, where the cords 2 are wound around the bale 1 in string planes which are substantially parallel to one another and with a first pair of opposite side faces 3 and 4 of the straw ball. The apparatus comprises a support surface 5, for example a table against which the underside 6 of the straw bale 15 1 abuts. In a slot 7 in the support surface 5, a cutting member 8 rotating in the illustrated embodiment is mounted for reciprocating movement in a direction perpendicular to the string planes between the side faces 3 and 4 for cutting the strings in all the string planes.

En i forhold til understøtningsfladen 5 stationær bærekonstruktion omfatter et portalarrangement med lodrette opstandere 9-12 og vandrette overliggere 13-16.A stationary support structure relative to the support surface 5 comprises a portal arrangement with vertical uprights 9-12 and horizontal overlays 13-16.

25 I bærekonstruktionen er over halmballen l lej ret en som helhed med 17 betegnet snoraftageindretning på en sådan måde, at den dels kan bevæges vandret hen over halmballen l's overside 18 vinkelret på snorplanerne mellem sidefladerne 3 og 4, dels kan udføre en 30 lodret bevægelse over en begrænset længde af de lodrette opstandere som nærmere forklaret i det følgende.25 In the supporting structure, a straw assembly 1 is mounted above the straw bale 1 as a whole, so that it can be moved horizontally across the upper side 18 of the straw bale 1 perpendicular to the string planes between the side surfaces 3 and 4 and partly can carry out a vertical movement over a limited length of the vertical uprights as explained below.

I den viste udførelsesform omfatter snoraftage-indretningen to vandrette traverser 19 og 20 i forbindelse med fortandede føringsorganer 21 i de lod- 35 rette opstandere 9-12.In the illustrated embodiment, the drawbar assembly comprises two horizontal crossers 19 and 20 in conjunction with toothed guide members 21 in the vertical uprights 9-12.

Til oversiden af traverserne 19 og 20 er fastgjort fx fortandede føringsorganer 22 for en slæ- DK 169739 B1 4 de 23, hvori selve snor aftageorganet, der i den viste udførelsesform er udformet som en snoropvikletromle 24, hvortil der er forbundet et fangorgan, fx et kroglignende organ 25, er ophængt. Som drivorgan for slæ-5 den 23' s vandrette bevægelse på traverserne 19 og 20 tjener en motor 26, som over en transmis s ions indretning 27 driver tandhjul 28, som er i indgreb med de fortandede føringsorganer 22 på traverserne 19 og 20. Med dette drivarrangement kan slæden 23 som 10 nævnt bringes til at bevæge sig i vandret retning langs traverserne 19 og 20 fra en udgangsstilling ved sidefladen 3 af den i fig. 1 viste halmballe 1 til en stilling ved den modstående sideflade 4. Under denne bevægelse vil fangorganet 25 som antydet i fig. 1 15 gribe de forinden ved halmballens underside 6 over-skårne snore og trække dem over mod halmballens sideflade 4. Denne fangebevægelse foregår uden rotation af opvikletromlen 24.To the upper side of the traverses 19 and 20 is fixed, for example, toothed guide means 22 for a trailing 23, in which the string itself takes off, which in the illustrated embodiment is formed as a string winding drum 24, to which a captive means, e.g. hook-like member 25 is suspended. As a driving member for the horizontal movement of the tow 23 on the traverses 19 and 20, serves a motor 26 which drives a gear 28 over a transmission device 27 which engages the toothed guide means 22 on the traverses 19 and 20. With this drive arrangement, as mentioned 10, the carriage 23 can be caused to move in a horizontal direction along the traverses 19 and 20 from an initial position at the side surface 3 of the one shown in FIG. 1 to a position at the opposite side surface 4. During this movement, the catch 25 as indicated in FIG. 1 15 they grasp the front strings at the underside of the straw bale 6 over-cut cords and pull them towards the side surface of the straw bale 4. This trapping movement takes place without rotation of the winding drum 24.

Når opvikletromlen 24 har nået slutstillingen 20 udenfor halmballen l's sideflade 4, sænkes traverserne 19 og 20, hvilket fx kan ske ved hjælp af ikke viste luftcylindre således at opvikletromlen 24 bringes til en position 24a umiddelbart under halmballen l's overside 18. I denne stilling bringes opvikletromlen 25 24 nu til at udføre en roterende opviklebevægelse, hvortil drivkraften leveres fra en motor 29, som over en transmissionsindretning 30 og en tandrem 31 driver opvikletromlen 24. Herved vil snorene 2, som under den ovenfor beskrevne fangbevægelse er trukket over 30 mod halmballens sideflade 4 blive viklet omkring tromlen 24. For at sikre at snorene holdes sammen under opviklebevægelse er der mod traverserne 19 og 20 forbundet tværgående udliggere 34 og 35, som afgrænser en mellemliggende snæver snorføringsspalte 36 ud for 35 fangorganet 25.When the winding drum 24 has reached the final position 20 outside the side surface 4 of the straw bale 1, the traverses 19 and 20 are lowered, for example by means of air cylinders not shown, so that the winding drum 24 is brought to a position 24a immediately below the top side of the straw bale 1. 25 24 to perform a rotary winding movement to which the driving force is supplied from a motor 29 which drives a winding drum 24 over a transmission device 30 and a toothed belt 31. Hereby, the cords 2 which are pulled over the straw surface side surface 4 as described above, For example, to be wound around the drum 24. To ensure that the cords are held together by winding motion, transverse outriggers 34 and 35 are connected to the traverses 19 and 20, which define an intermediate narrow guide guide gap 36 off the catch 25.

Efter denne opvikling bringes traverserne 19 og 20 og den derpå hvilende slæde 23 ved en lodret DK 169739 B1 5 bevægelse opefter til en stilling, hvor opvikletromlen 24b bringes i kontakt med et roterende skæreorgan 32, som er lejret i et til den ene af de vandrette overliggere 16 fastgjort hus 33. Efter at de på tromlen 24 5 opviklede snore på denne måde er frigjort og umiddelbart kan fjernes fra tromlen, føres slæden 23 i denne hævede stiling af snoraftageindretningen tilbage til udgangspositionen med tromlen 24 placeret ved sidefladen 3 af en ny halmballe 1.After this winding, the traverses 19 and 20 and the then-resting carriage 23 are brought upwards in a vertical movement upwards to a position where the winding drum 24b is brought into contact with a rotary cutting member 32 which is mounted in one of the horizontal baffles 16 attached housing 33. After the cords wound on the drum 24 5 are thus released and can be immediately removed from the drum, the sled 23 in this raised position of the cord removal device is returned to the starting position with the drum 24 located at the lateral surface 3 of a new straw bale. first

10 Når en halmballe 1 er anbragt på understøt ningsfladen 5 som vist i fig. 1, foretages først overskæring af snorene ved halmballens underside 6 ved hjælp af det roterende og frem- og tilbagegående skæreorgan 8 under bevægelse af dette fra halmballens 15 sideflade 3 til sidefladen 4. Derefter udføres den ovenfor beskrevne fangebevægelse ved at slæden 23 køres vandret henover halmballen l's overside 18 med opviklet tromle 24 og fangorganet 25 i anlæg mod halmballens overside. Når tromlen 24 har nået en 20 stilling udenfor halmballens sideflade 4, aktiveres motoren 29 efter sænkning af traverserne 19 og 20 til den i fig. 1 viste stilling 24a af tromlen 24, hvorved snorene 2 opvikles på tromlen. Endelig føres traverserne 19 og 20 opefter, således at tromlen 24 25 bringes til stillingen 24b, hvor de opviklede snore overskæres ved selektiv aktivering af det roterende skæreorgan 32.10 When a straw baler 1 is placed on the support surface 5 as shown in FIG. 1, the strings are first cut at the underside 6 of the straw bale by means of the rotating and reciprocating cutting member 8, moving it from the side surface 3 of the straw bale 15 to the side surface 4. Thereafter, the capturing movement described above is carried out by moving the carriage 23 horizontally across the straw bale. 1's upper side 18 with wound drum 24 and catch member 25 abutting the top of the straw ball. When the drum 24 has reached a position 20 outside the straw surface side surface 4, the motor 29 is activated after lowering the traverses 19 and 20 to the position shown in FIG. 1 shows position 24a of the drum 24, whereby the cords 2 are wound on the drum. Finally, the traverses 19 and 20 are moved upwardly so that the drum 24 25 is brought to the position 24b where the wound cords are cut by selectively activating the rotary cutting member 32.

Det bemærkes, at snoraftageindretningen ikke behøver at være udført som vist på tegningen, idet man 30 ved en mere enkel udførelse fx kan undvære den roterende opviklebevægelse, hvorved de hertil nødvendige driv-og transmissionsorganer bortfalder. Ligeledes behøver snoroverskæring og -opfangning ikke nødvendigvis at ske henholdsvis ved undersiden og oversiden af halmballen 35 men kan fx udføres ved det andet par modstående sideflader, som er vinkelrette på snorplanerne.It should be noted that the drawbar assembly does not have to be designed as shown in the drawing, for example, in a simpler embodiment, the rotary winding movement can be dispensed with, thereby eliminating the necessary drive and transmission means. Likewise, cord cutting and intercepting do not necessarily have to occur at the underside and upper side of the straw bale 35, but may, for example, be performed at the second pair of opposite side surfaces perpendicular to the string planes.
