The basic design of the saw is such that the overhang table is at such an angle that the workpieces move independently after it. The patent relates to the construction of an existing saws frame with an overhang table at an angle and a strip (6) with a mechanism for detecting the workpiece presence at the end of the overhang table (3), the manual actuation keys (4), the solenoid valve (5) and the hydraulic movement mechanism (1). An automated saw in the presence of a workpiece at the end of the overhang automatically activates the working stroke. The sawn workpiece is ejected, and the second part of the workpiece is moved again after the overhang table and again pressed on the mechanism for checking the presence of the workpiece (3), so that the working stroke is reactivated.

Description

Avtomatizacija žage s previsno mizo pod kotomAutomation of the saw with an overhanging table at an angle

Predmet izuma je avtomatizacija žage za drva s previsno mizo pod kotom, ki uporablja več mehanizmov za aktivacijo pomika previsne mize. Žaga za drva s previsno mizo pod kotom je kmetijski stroj namenjen žaganju lesa za kurjavo.The subject of the invention is the automation of a wood saw with an overhang table at an angle that uses several mechanisms for activating the overhang table. A wood saw with an overhanging table at an angle is an agricultural machine designed to burn wood for heating.

Tehnični problem, ki ga rešuje izum, je mehanizem za proženje delovnega giba previsne mize in mehanizem za pomik previsne mize s pomočjo hidravlike. Proženje je lahko izvedeno ročno ali avtomatsko. Ročni način predstavlja proženje previsne mize s pritiskom na tipko, ki je ergonomično nameščena na stroj in z njo upravlja delavec. Pri avtomatskem načinu mehanizem za zaznavanje prisotnosti obdelovanca, zazna prisotnost in avtomatsko aktivira delovni gib previsne mize.The technical problem solved by the invention is a mechanism for triggering a working table of the overhead table and a mechanism for moving the overhang table using hydraulics. The activation can be done manually or automatically. Manual mode represents the trigger of the overhead table by pressing the key, which is ergonomically mounted on the machine and controlled by the worker. In automatic mode, the workpiece presence detection mechanism detects the presence and automatically activates the working stroke of the overhead table.

Poznana je krožna žaga po patentu EU PATENT 15158857.1 / 12.03.2015. Ki opisuje obliko in namen uporabe žage s previsno mizo pod kotom, vendar je delovni pomik izveden le ročno. Delo s takšno žago je lahko precej utrujajoče, za to smo se odločili žago nadgraditi z avtomatskim pomikom delovnega giba.A circular saw is known under the EU patent PATENT 15158857.1 / 12.03.2015. It describes the shape and purpose of using a saw with an overhanging table at an angle, but the working shift is only performed manually. Working with such a saw can be quite tiring, for this we decided to upgrade the saw using automatic movement of the working motion.

Skupna značilnost zgoraj navedenih patentov je oblika žage. Previsna miza pod določenim kotom omogoča avtomatsko pomikanje obdelovanca v delovno območje. Z našim izumom smo zadevo nadgradili in jo popolnoma avtomatizirali.The common feature of the above patents is the shape of the saw. An overhead table at a certain angle enables automatic movement of the workpiece to the working area. With our invention, we upgraded the matter and completely automated it.

Po izumu je problem rešen z dvema načinoma proženja delovnega giba previsne mize. Delovni gib je pomik previsne mize iz mirujočega - prostega položaja v drugo skrajno lego. Med delovnim gibom list žage prečka rezalno območje, ki je namenjeno obdelovancu. Obdelovanec med gibom prereže. V tem gibu je list žage v območju rezanja izpostavljen in ni zaščiten. Povratni pomik je izveden avtomatsko s pomočjo vzvodov in vzmeti. List žage se vme v začetni položaj, kjer je skrit in popolnoma nedostopen.According to the invention, the problem is solved by two means of activating the working motion of the overhead table. The working stroke is the movement of the overhang from a stationary - free position to another extreme position. During the working stroke, the saw blade traverses the cutting area intended for the workpiece. The workman cuts during the movement. In this movement, the saw blade is exposed in the cutting area and is not protected. The reverse movement is performed automatically with the help of levers and springs. The saw blade is placed in its initial position where it is hidden and completely inaccessible.

Prvi način aktivacije delovnega giba je ročni, kjer s tipko aktiviramo delovni gib previsne mize. Ta način proženja je mogoče izvesti kadarkoli, tudi takrat, ko v previsni mizi ni obdelovanca. Tipka je nameščena na stroju na vami lokaciji, s katere je nemogoče dostopati do nevarnih, ostrih in vrtečih se delov stroja. Drugi način proženja se izvaja avtomatsko in je za to potrebna prisotnost obdelovanca na koncu previsne mize. Za zaznavanje prisotnosti je izdelan preprost mehanizem, ki je stvar tega izuma in bo detajlno opisan v nadaljevanju.The first mode of activation of the working motion is a manual one, where the key of the overclocking table activates with the key. This mode of activation can be performed at any time, even when there is no workpiece in the overhang table. The button is located on the machine at you location, from which it is impossible to access the dangerous, sharp and rotating parts of the machine. The second mode of triggering is performed automatically and requires the presence of the workpiece at the end of the overhang table. A simple mechanism is created to detect the presence, which is a matter of this invention and will be described in detail below.

Izum bo opisan na izvedenem primeru in slikah, ki prikazujejoThe invention will be described in the embodiment and the illustrations shown

Sl. 1 žaga s previsno mizo pod kotomFig. 1 saw with an overhanging table at an angle

Sl. 2 mehanizem za zaznavanje obdelovancaFig. 2 workpiece detection mechanism

Sl. 1 prikazuje žago s previsno mizo pod kotom in tekočem traku. Žaga je namenjena žaganju polenov, drvov in vej premera od 4 do 24 centimetrov. Žaga je lahko gnana na traktor preko kardanskega pogona ali elektromotoija. Na ogrodje je poleg lista žage, hidravličnega ali električnega pogona, traku za transport drv, tritočkovnega priklopa, nog oz. podstavka in zaščitnih pokrovov pritijena tudi previsna miza. Previsna miza (2) je pod kotom pritrjena na ogrodje žage (6) s tečaji, ki s pomočjo hidravličnega mehanizma za izvajanje delovnega giba (1) omogoča pomik mize v delovno območje. Drva se dozirajo skozi odprtino na previsni mizi (2) in se zaradi teže in pravilnega kota avtomatsko popeljejo do mehanizma za zaznavanje prisotnosti obdelovanca (3) na koncu previsne mize. Druga opcija je tipka za proženje delovnega giba (4), ki je pritrjena na ogrodje žage (6) in je postavljena ob previsno mizo na pozicijo s katere ni mogoče segati delovni prostor stroja. V obeh primerih proženja delovnega giba se ob prisotnosti signala iz mehanizma za zaznavanje prisotnosti obdelovanca (3) ali s tipke (4) sproži elektromagnetni ventil (5).Fig. 1 shows a saw with an overhang table and a conveyor belt. The saw is intended for sawing pollen, wood and branches with a diameter of 4 to 24 centimeters. The saw can be driven to the tractor via a PTO or electromotor. On the frame there is a saw blade, a hydraulic or electric drive, a timber for the transport of logs, a three-point connection, the base and protective covers are also attached to the overhang table. The overpressing table (2) is at an angle fixed to the frame of the saw (6) with hinges, which allows the table to move the work area with the aid of a hydraulic mechanism for carrying the working stroke (1). The wood is fed through the aperture on the overhang table (2) and, due to the weight and the correct angle, it automatically moves to the mechanism for detecting the presence of the workpiece (3) at the end of the overhang table. The second option is the actuation pushbutton (4), which is attached to the frame of the saw (6) and is positioned at the overpass table at a position from which the working area of the machine can not be reached. In both cases of triggering of the working motion, an electromagnetic valve (5) is triggered in the presence of the signal from the mechanism for detecting the presence of the workpiece (3) or the key (4).

Sl. 2 detajlno prikazuje mehanizem za zaznavanje prisotnosti obdelovanca (3) na koncu previsne mize iz sl. 1. Mehanizem je sestavljen iz omejevala drv (3.2), ki ga z ročajem (3.5) v celoti premikamo in nastavljamo dolžino odrezanih obdelovancev - drv. Izbrano dolžino zaklenemo z vzvodom za izbiro dolžine (3.3). Zaznavanje prisotnosti obdelovanca je izvedeno s ploščo, kije s tečaji (3.6) pritijena na omejevalo drv (3.2). Plošča (3.1) je oblikovana tako, da omogoča zaznavanje vseh vrst, premerov in oblik obdelovancev - drv. Signal prisotnosti zajamemo s merjenjem prisotnosti in oddaljenosti plošče (3.1) do senzorja (3.4).Fig. 2 shows a mechanism for detecting the presence of a workpiece (3) at the end of the overhang table of Fig. 1. The mechanism consists of the limiter of the logs (3.2), which is completely moved by the handle (3.5) and the length of the cut pieces is adjusted - log. The selected length is locked with a lever for selecting the length (3.3). The detection of the presence of the workpiece is carried out with a plate, which is attached to the limiter (3.2) by the hinges (3.6). The panel (3.1) is designed to allow for the detection of all types, diameters and shapes of workpieces - wood. The presence signal is detected by measuring the presence and distance of the plate (3.1) to the sensor (3.4).
