Abstract
Izum sodi na področje delovnih strojev, bolj natančno na področje delovanja izmeta in sesanja žagovine na rezalnih in rezalno cepilnih strojih. Pričujoči izum se nanaša na vgradno odsesovalno enoto za rezalne in rezalno-cepilne stroje ter stroje z omenjenim odsesovalno enoto. Bistvo izuma je v tem, da je pogon odsesovalne enote pogon samega cepilnega ali cepilno rezalnega stroja, pri čemer je ventilator odsesovalne enote posredno povezan z gredjo stroja, pogonsko jermenico, verižnikom ali zobnikom stroja,ki je pritrjen na vrtljivi del pogona, ali pa na kardansko gred, preko katere se poganja stroj. Povezava odsesovalne enote z ventilatorjem, ki sesa žagovino iz dovodnega kanala v izmetni kanal, na gred je lahko z jermeni, verigo, zobniki in podobnimi prenosi vrtilnega momenta in glavne gredi. Ventilator vleče žagovino iz ohišja stroja in preko kanala z izhodom izloča žagovino v zbiralnik, ki je lahko vreča ali pa ustrezno oblikovana posoda. Konstrukcija odsesovalne enote omogoča, da le-ta dela vsakič, kodela tudi stroj, kar pomeni, da se žagovina dosledno odvaja in zbira v ustreznem zbiralniku.The invention belongs to the field of working machines, more precisely to the field of ejection and suction of sawdust on cutting and splitting machines. The present invention relates to a built-in suction unit for cutting and cutting-splitting machines and machines with said suction unit. The essence of the invention is that the drive of the extraction unit is the drive of the splitting or splitting cutting machine itself, whereby the fan of the extraction unit is indirectly connected to the shaft of the machine, the drive pulley, chain or gear of the machine, which is attached to the rotating part of the drive, or to cardan shaft through which the machine is driven. The connection of the suction unit with the fan, which sucks the sawdust from the supply channel to the discharge channel, to the shaft can be with belts, chains, gears and similar transmissions of the torque and the main shaft. The fan draws the sawdust from the machine housing and discharges the sawdust through the outlet channel into the collector, which can be a bag or a suitably designed container. The design of the extraction unit allows it to work every time, even the machine, which means that the sawdust is consistently removed and collected in the appropriate collector.

Ozadje izuma in tehnični problemBackground of the Invention and Technical Problem
Les se že dolgo časa uporablja za gretje, za uporabo pa mora biti primerne velikosti in oblike. Pri obdelavi hlodov je zaželen razrez na polena, ki so primerne velikosti, da se lahko brez dodatnega razreza oziroma cepljenja uporabljajo v različnih kuriščih. Poznanih je veliko različnih naprav za obdelavo lesa, ki režejo in cepijo hlodovino z minimalnim ročnim ravnanjem. Pri cepljenju hlodovine nastaja žagovina, ki se lahko nabira in/ali leti proti operaterju rezalno-cepilnega stroja. Zato imajo številni stroji posebne odprtine in/ali cevi za vodenje žagovine, kot je to opisano v dokumentih US4621668 in US2075282, ali pa imajo stroji vgrajene odsesovalne naprave, ki skrbijo za odvajanje žagovine in njen transport izven stroja, na primer v ustrezen zbiralnik. Omenjene odsesovalne enote so lahko zunanje oziroma samostojne, ki se lahko priklopijo na stroj, ali notranje, torej vgrajene v sam stroj.Wood has been used for heating for a long time, and it must be of the right size and shape to be used. When processing logs, it is desirable to cut them into logs of suitable size so that they can be used in different fireplaces without additional cutting or splitting. A wide variety of woodworking machines are known that cut and split logs with minimal manual handling. When splitting a log, sawdust is produced, which can accumulate and/or fly towards the operator of the splitter. Therefore, many machines have special openings and/or pipes for guiding the sawdust, as described in the documents US4621668 and US2075282, or the machines have built-in suction devices that take care of the removal of the sawdust and its transport outside the machine, for example to a suitable collector. The mentioned extraction units can be external or independent, which can be connected to the machine, or internal, i.e. built into the machine itself.
Znane odsesovalne naprave so gnane z lastnim pogonom, ki je bodisi hidravlični ali pa ločen elektromotor ali hidromotor. Slabost slednjih je v tem, da mora biti stroj vedno blizu vira elektrike, da odsesovalna enota deluje, kar pa še posebno v primeru dela na terenu ni pogosto izpolnjeno. Posledično odsesovanje ne deluje, žagovina se ne odvaja ter leti vsepovsod, s čemer otežuje in upočasnjuje delo, kar posledično vpliva na produktivnost. Tudi hidravlično gnane odsesovalne naprave imajo slabosti, saj nepotrebno obremenjujejo hidravlični sistem, kar posledično vpliva na optimalno delo s strojem in življenjsko dobo stroja. V takšnih primerih so potrebne tudi večje črpalke, rezervoarji olja, ventili, cevi, kar pa ni najbolj ekonomično.Known suction devices are driven by their own drive, which is either hydraulic or a separate electric motor or hydromotor. The disadvantage of the latter is that the machine must always be close to an electricity source for the extraction unit to work, which is often not fulfilled, especially in the case of field work. As a result, the suction does not work, the sawdust is not removed and flies everywhere, making work difficult and slow, which in turn affects productivity. Hydraulically driven extraction devices also have disadvantages, as they unnecessarily strain the hydraulic system, which in turn affects the optimal work with the machine and the life of the machine. In such cases, larger pumps, oil tanks, valves, pipes are also needed, which is not the most economical.
Tehnični problem je torej vezan na rešitev pomanjkljivosti znanih odsesovalnih naprav in optimizacija pogona le-teh.The technical problem is therefore related to the solution of the shortcomings of known extraction devices and the optimization of their drive.

Uporabni model CN205343349 opisuje žago, ki ima v spodnjem delu ohišja napravo za odstranjevanje žagovine, ki preko cevi izmeče žagovino stran od uporabnika. Podobno rešitev opisuje tudi patentna prijava EP1878526A opisuje krožno žago, ki ima ohišje z izhodom za žagovino, kamor se namesti zbiralnik za žagovino.Utility Model CN205343349 describes a saw that has a sawdust removal device in the lower part of the housing that ejects the sawdust away from the user via a tube. A similar solution is also described in patent application EP1878526A, which describes a circular saw that has a housing with a sawdust outlet where a sawdust collector is installed.
Patentna prijava US4228708A opisuje rezalno cepilno napravo, ki ima sistem za zbiranje žagovine s pokrovom okoli rezil žage in poleg rezil nameščeno odvodno cev. Pogon je motor, ki je nameščen na nosilcu z osjo in kolesi.Patent application US4228708A describes a cutting splitter that has a sawdust collection system with a cover around the saw blades and a discharge tube located next to the blades. The drive is a motor mounted on a support with an axle and wheels.
Patentna prijava GB776039 opisuje stroj za razrez hlodovine v drva, ki ima cepilne žage, ki jih poganja vsaj en motor, hkrati pa tudi napravo za odstranjevanje žagovine, ki je v bistvu neskončni trak, ki ga poganja ločen motor.Patent application GB776039 describes a machine for cutting logs into firewood which has splitting saws driven by at least one motor and also a sawdust removal device which is essentially an endless belt driven by a separate motor.
Vse opisane rešitve se razlikujejo od pričujočega izuma, ker nimajo pogona ali pa imajo že znane ločene pogone odsesovalne enote.All described solutions differ from the present invention in that they do not have a drive or have already known separate drives of the extraction unit.
Opis rešitve tehničnega problemaDescription of the solution to the technical problem
Tehnični problem je rešen, kot je predstavljeno v neodvisnem patentnem zahtevku, medtem ko so prednostne izvedbe rešitve tehničnega problema predstavljene v odvisnih zahtevkih.The technical problem is solved as presented in the independent patent claim, while preferred embodiments of the solution to the technical problem are presented in the dependent claims.
Bistvo izuma je v tem, da je pogon odsesovalne enote vezan na pogon samega rezalnega ali rezalno-cepilnega stroja, pri čemer je ventilator odsesovalne enote direktno ali posredno preko vsaj enega prenosa povezan z gredjo stroja, na primer na pogonsko jermenico, ki je pritrjena na vrtljivi del pogona, ali na kardansko gred, preko katere se poganja rezalni ali rezalno-cepilni stroj. Povezava ventilatorja na gred je lahko z jermeni, verigo, zobniki in podobnimi prenosi vrtilnega momenta in glavne gredi. Ventilator sesa žagovino iz zbiralnega oziroma dovodnega kanala v zbiralnik, ki je lahko vreča ali pa ustrezno oblikovana posoda. Konstrukcija odsesovalne enote omogoča, da le-ta dela vsakič, ko dela tudi stroj, kar pomeni, da se žagovina dosledno odvaja in zbira v ustreznem zbiralniku.The essence of the invention is that the drive of the extraction unit is connected to the drive of the cutting or cutting-splitting machine itself, whereby the fan of the extraction unit is connected directly or indirectly via at least one transmission to the shaft of the machine, for example to the drive pulley, which is attached to rotating part of the drive, or to the cardan shaft, through which the cutting or cutting-splitting machine is driven. The connection of the fan to the shaft can be by belts, chains, gears and similar transmissions of the torque and the main shaft. The fan sucks the sawdust from the collection or supply channel into the collector, which can be a bag or a suitably designed container. The design of the extraction unit allows it to work every time the machine is working, which means that the sawdust is consistently removed and collected in the appropriate collector.
Po prednostnem izvedbenem primeru je odsesovalna enota sestavljena iz:According to the preferred embodiment, the extraction unit consists of:
- ohišja, znotraj katera je nameščen ventilator, vhod za povezavo na dovodni kanal in izhod za povezavo na izmetni kanal,- the housing inside which the fan is installed, the inlet for connection to the supply duct and the outlet for connection to the exhaust duct,
- ventilatorja, ki je togo pritrjen na os odsesovalne enote, na kateri je nameščena tudi pogonska jermenica, verižnik ali zobnik odsesovalne enote, pri čemer je omenjena jermenica, verižnik ali zobnik odsesovalne enote preko prirobnice in omenjene osi pritrjena na ohišje odsesovalne enote, pri čemer ventilator z vrtenjem ustvarja podtlak, s čemer sesa žagovino iz dovodnega kanala (prednostno cevi) in jo pošilja preko izmetnega kanala (prednostno cevi) v zunanjost v ustrezen zbiralnik, ki je lahko vreča ali podoben vsebnik za zbiranje žagovine,- a fan that is rigidly attached to the axis of the extraction unit, on which the drive pulley, chain or gear of the extraction unit is also mounted, wherein said pulley, chain or gear of the extraction unit is attached to the housing of the extraction unit via the flange and said axis, whereby the fan creates a negative pressure by rotating, which sucks the sawdust from the supply channel (preferably a pipe) and sends it through the discharge channel (preferably a pipe) to the outside into a suitable collector, which can be a bag or similar container for collecting sawdust,
- dovodnega kanala, katerega prvi konec sega v notranjost stroja, drugi konec pa je nameščen na omenjeni vhod ohišja odsesovalne enote z ventilatorjem, izmetnega kanala, ki je nameščen na izhod ohišja, drugi konec pa sega v zunanjost stroja ali pa se konča na ohišju stroja, pri čemer je na koncu izmetne cevi po izbiri nameščena vreča, zbiralnik ali drug element za zbiranje žagovine, konec izmetne cevi pa ima lahko ustrezno prirobnico ali podoben element za boljšo povezavo na vrečo oziroma primeren zbiralnik žagovine, ter- the inlet duct, the first end of which extends into the interior of the machine, and the other end is installed at the mentioned inlet of the casing of the extraction unit with the fan, the exhaust duct, which is installed at the outlet of the casing, and the other end extends into the exterior of the machine or ends at the machine casing , whereby a bag, collector or other element for collecting sawdust is optionally installed at the end of the discharge pipe, and the end of the discharge pipe can have a suitable flange or similar element for a better connection to the bag or a suitable sawdust collector, and
- poljubne namestitvene plošče ali podobne elemente za fiksacijo ohišja odsesovalne enote v rezalni oziroma rezalno-cepilni stroj, kjer se fiksacija lahko izvede na katerikoli primeren način, prednostno z vijačenjem.- any installation plates or similar elements for fixing the housing of the suction unit in the cutting or cutting-splitting machine, where the fixation can be done in any suitable way, preferably by screwing.
Dovodni kanal je prednostno speljan v središče stranske plošče ohišja, lahko pa tudi v kateri drugi del ohišja, v katerem je ventilator, povezava je narejena z varjenjem ali pa katerim drugim primernim načinom spajanja. Dovodni kanal na drugem koncu sega v notranjost stroja, kjer med postopkom rezanja lesa nastaja žagovina. Zaradi delovanja odsesovalne enote hkrati s cepljenjem oziroma rezanjem ter posledičnega delovanja ventilatorja, nastaja podtlak, ki pozroči, da nastala žagovina zapušča notranjost stroja po dovodnem kanalu proti ventilatorju, kjer se potem usmeri v izmetni kanal, ki žagovino vodi v okolico stroja ali prednostno v primeren zbiralnik.The supply channel is preferably led to the center of the side panel of the case, but it can also be in any other part of the case where the fan is located, the connection is made by welding or any other suitable connection method. The feed channel at the other end reaches inside the machine, where sawdust is produced during the wood cutting process. Due to the operation of the extraction unit at the same time as splitting or cutting and the resulting operation of the fan, a negative pressure is created, which causes the resulting sawdust to leave the interior of the machine through the inlet channel towards the fan, where it is then directed into the discharge channel, which leads the sawdust to the surroundings of the machine or preferably to a suitable collector.
Prednostno je povezava na pogon izvedena preko vsaj enega prenosa, lahko pa se uporabi dva ali več prenosov, odvisno od pogona stroja kot tudi pozicije, kjer je odsesovalna enota nameščena. Najbolj prednostno se za povezavo pogona stroja s pogonskim delom odsesovalne enote oziroma ventilatorja, ki je prednostno jermenica, uporabi pogonski jermenski prenos, ki poganja odsesovalno enoto. Pogonska jermenica stroja je fiksirana na vrtljivi del ene izmed vrtljivih gredi na stroju ali kardanske gredi, ki se nahaja na hidravlični črpalki ali multiplikatorju, na katerega je priključena hidravlična črpalka.Preferably, the connection to the drive is made via at least one transmission, but two or more transmissions can be used, depending on the machine's drive as well as the position where the extraction unit is installed. Most preferably, a drive belt transmission is used to connect the drive of the machine to the drive part of the extraction unit or the fan, which is preferably a pulley, which drives the extraction unit. The drive pulley of the machine is fixed to the rotating part of one of the rotating shafts on the machine or cardan shaft located on the hydraulic pump or multiplier to which the hydraulic pump is connected.
Omenjena pogonska jermenica je v primeru uporabe kardanske gredi prednostno togo vezana na kardansko gred preko naseda in zatik vijakov. Moč za pogon jermenice se odvzema iz kardanske gredi, kije priključena na traktorski ali elektro pogon. Pogonska jermenica je preko klinastega jermena povezana na manjšo vmesno jermenico, ki se nahaja na nosilcu za zategovanje pritrjenem na ogrodju stroja, pri čemer omenjeni nosilec za zategovanje jermena skrbi za ustrezno nastavljanje napetosti jermena. Zategovanje je lahko izvedeno na katerekoli primerne načine, ki so poznani strokovnjaku na področju. Omenjena manjša vmesna jermenica je preko uležajene povezovalne gredi povezana z veliko jermenico odsesovalne enote in posledično pogonsko jermenico odsesovalne enote, ki sta povezani z drugim klinastim jermenom. Pogonska jermenica je povezana z ventilatorjem, kot je opisano zgoraj. Povezovalna gred je lahko zaščitena z ustrezno zaščitno ploščico, pločevino ali podobnim elementom. V kolikor bi bil namesto jermena uporabljen verižni prenos, bi bila konstrukcija povsem analogna, kot je jasno strokovnjaku na področju.In the case of using a cardan shaft, the mentioned drive pulley is preferably rigidly connected to the cardan shaft via a set and pin of screws. The power to drive the pulley is taken from the cardan shaft, which is connected to the tractor or electric drive. The drive pulley is connected via a V-belt to a smaller intermediate pulley, which is located on a tensioning bracket attached to the frame of the machine, whereby the mentioned belt tensioning bracket takes care of the proper adjustment of the belt tension. Tightening may be accomplished by any suitable means known to one skilled in the art. The aforementioned smaller intermediate pulley is connected to the large pulley of the extraction unit and the drive pulley of the extraction unit via a mounted connecting shaft, which are connected to another V-belt. The drive pulley is connected to the fan as described above. The connecting shaft can be protected by a suitable protective plate, sheet metal or similar element. If a chain transmission were used instead of a belt, the construction would be completely analogous, as is clear to a person skilled in the art.
Po alternativni izvedbi, kjer ni uporabljena kardanska gred, je pogonska jermenica ventilatorja povezana z veliko jermenico preko klinastega jermena, omenjena velika jermenica pa je pritrjena na eno stran gredi, ki je na drugi strani opremljena s stezno pušo, s katero je togo povezana na eno izmed vrtečih se gredi rezalnega ali rezalnocepilnega stroja. Lahko pa je omenjena povezovalna gred namesto s pušo in direktno povezavo na eno izmed vrtečih se gredi, povezana na malo jermenico, ki je preko drugega klinastega jermena povezana na pogonsko jermenico rezalnega ali rezalnocepilnega stroja. Omenjena povezovalna gred je na vsako jermenico povezana preko sklopke ali drugega ustreznega strojnega elementa za prenašanje vrtilnega momenta, lahko pa je tudi dodatno zaščitena pred poškodbami s pomočjo zaščitne pločevine pritrjene na ohišje sestalne enote. Velikost jermenic je odvisna od prestavnega razmerja, ki je potreben, kar je odvisno od vhodnih obratov, s prestavo pa se potrebne končne obrate. Teoretično bi bili lahko velika in mala jermenica enaki po velikosti, vendar pa je najbolj optimalno, če sta različnih velikosti. Enak princip povezave bi bil lahko uporabljen tudi v primeru verig in verižnikov.According to an alternative embodiment, where no cardan shaft is used, the fan drive pulley is connected to the large pulley via a V-belt, and the said large pulley is attached to one side of the shaft, which is equipped with a track bush on the other side, with which it is rigidly connected to one from the rotating shafts of a cutting or splitting machine. However, instead of a bushing and a direct connection to one of the rotating shafts, the mentioned connecting shaft can be connected to a small pulley, which is connected via another V-belt to the drive pulley of the cutting or splitting machine. The mentioned connecting shaft is connected to each pulley via a clutch or other suitable mechanical element for transmitting torque, but it can also be additionally protected from damage by means of a protective sheet attached to the housing of the assembly unit. The size of the pulleys depends on the gear ratio required, which depends on the input revolutions, and with the gear, the final revolutions required. In theory, the large and small pulleys could be the same size, but it is most optimal if they are different sizes. The same connection principle could be used in the case of chains and chains.
Odsesovalna enota je vgrajena v katerikoli rezalni oziroma rezalno-cepilni stroj, kjer je pritrjena na ogrodje na katerikoli primeren način. Izum omogoča sesanje ali zbiranje žagovine pri razrezu v vrečo ali posodo, s čemer se zmanjša izmet žagovine proti operaterju.The extraction unit is built into any cutting or cutting-splitting machine, where it is attached to the frame in any suitable way. The invention enables suction or collection of sawdust during cutting into a bag or container, thereby reducing sawdust ejection towards the operator.

- Izmetnega kanala 12, ki je nameščen na izhod 1b ohišja 1, drugi konec pa sega v zunanjost stroja ali pa se konča na ohišju stroja, — pri čemer je na koncu izmetnega kanala 12 po izbiri nameščena vreča, zbiralnik ali drug element za zbiranje žagovine, konec izmetnega kanala 12 pa ima lahko ustrezno prirobnico ali podoben element za boljšo povezavo na vrečo oziroma primeren zbiralnik žagovine, ter- The discharge channel 12, which is installed at the outlet 1b of the housing 1, and the other end extends to the outside of the machine or ends at the machine housing, — where at the end of the discharge channel 12, a bag, collector or other element for collecting sawdust is optionally installed , and the end of the ejection channel 12 can have a suitable flange or similar element for a better connection to the bag or a suitable sawdust collector, and
- poljubne namestitvene plošče 7, 8 ali podobne elemente za fiksacijo ohišja odsesovalne enote v rezalni oziroma rezalno-cepilni stroj, kjer se fiksacija lahko izvede na katerikoli primeren način, prednostno z vijačenjem.- any installation plates 7, 8 or similar elements for fixing the housing of the suction unit in the cutting or cutting-splitting machine, where the fixation can be done in any suitable way, preferably by screwing.
Sliki 1a in 1b prikazujeta odsesovalno enoto po prvem izvedbenem primeru, kjer je povezava na pogon stroja izvedena tako, da je pogonska jermenica 4 povezana z veliko jermenico 6 odsesovalne enote preko klinastega jermena 5. Povezovalna gred 9 je na eni strani pritrjena s pomočjo veznega strojnega elementa, prednostno puše 10, na eno izmed vrtljivih gredi na stroju (ni prikazana), na drugi strani pa je podprta z ležajem, ki je vpet na nosilec 7. Omenjena povezovalna gred 9 je na veliko jermenico 6 povezana preko sklopke, tako da se vrtilni moment prenaša iz pogona stroja preko povezovalne gredi 9 na veliko jermenico 6 in posledično na pogonsko jermenico 4 odsesovalne enote, kar povzroči delovanje ventilatorja 2 ter sesanje žagovine iz dovodnega kanala 11 v izmetni kanal 12.

Omenjena pogonska jermenica 15 je togo vezana na kardansko gred preko naseda in zatik vijakov. Moč za pogon jermenice 15 se odvzema iz kardanske gredi, ki je priključena na traktorski ali elektro pogon. Pogonska jermenica 15 je preko klinastega jermena 13 povezana na manjšo vmesno jermenico 14, ki se nahaja na nosilcu za zategovanje, ki omogoča namestitev in opcijsko zategovanje jermenov, ki je včasih potrebno. Omenjena manjša vmesna jermenica 14 je preko uležajene povezovalne gredi 9 povezana z veliko jermenico 6 odsesovalne enote in posledično pogonsko jermenico 4 odsesovalne enote, ki sta povezani z drugim klinastim jermenom 5. Pogonska jermenica 4 je povezana z ventilatorjem 2, kot je opisano zgoraj pri prvem izvedbenem primeru. Povezovalna gred 9 je zaščitena z ustrezno zaščitno ploščico, pločevino ali podobnim elementom 16. Tako se vrtilni moment prenaša na pogonsko jermenico 15 stroja, vmesno malo jermenico 14 ter preko gredi 9 in velike jermenice 6 posledično na pogonsko jermenico 4 odsesovalne enote, kar povzroči delovanje ventilatorja 2 ter sesanje žagovine iz dovodnega kanala 11 v izmetni kanal 12.Figures 2a to 2c show an embodiment when the drive of the machine is provided via the cardan shaft. The drive pulley of the machine 15 is fixed to the rotating part of the cardan shaft. The aforementioned drive pulley 15 is rigidly connected to the cardan shaft via a misalignment and a screw pin. The power to drive the pulley 15 is taken from the cardan shaft, which is connected to the tractor or electric drive. The drive pulley 15 is connected via a V-belt 13 to a smaller intermediate pulley 14 located on the tensioning bracket, which allows for the installation and optional tightening of the belts, which is sometimes necessary. The mentioned smaller intermediate pulley 14 is connected via a mounted connecting shaft 9 to the large pulley 6 of the extraction unit and consequently the drive pulley 4 of the extraction unit, which are connected to another V-belt 5. The drive pulley 4 is connected to the fan 2, as described above for the first implementation example. The connecting shaft 9 is protected by a suitable protective plate, sheet or similar element 16. Thus, the torque is transmitted to the drive pulley 15 of the machine, the intermediate small pulley 14 and via the shaft 9 and the large pulley 6 to the drive pulley 4 of the extraction unit, which causes the operation fan 2 and suction of sawdust from the inlet channel 11 into the discharge channel 12.
