Said holding device 12 is arranged in the direction of the treatment flow in front of the processing unit 11 such that the transport device 2 brings the workpiece 6 first to the holding device 12, which holds the workpiece 6 during processing.

[0012] Omenjena držalna priprava 12 obsega nosilec 16, ki je pritrjen k omenjenemu prečnemu nosilcu 13, in drsno vodilo 17, ki je obešeno na nosilcu 16, tako da je drsno vodilo 17 premakljivo glede na nosilec 16. Omenjeni nosilec 16 poteka v bistvu v ravnini, ki je vzporedna ravnini omenjene transportne naprave 2 oz. ravnini omenjenih transportnih verig 2'. Omenjeno obešenje drsnega vodila 17 na nosilcu 16 je zasnovano na način, da nosilec 16 obsega vsaj eno pritrdišče 18, prednostno dve pritrdišči 18, in da drsno vodilo obsega vsaj eno pritrdišče 19, prednostno dve pritrdišči 19, pri čemer sta pritrdišči 18 nosilca 16 zgibno povezani s pritrdiščema 19 drsnega vodila 17. V svojem nevtralnem položaju je drsno vodilo 17 razporejeno nad transportno napravo 2 na višini, ki je manjša od debeline obdelovanca 6. Omenjeno drsno vodilo 17 je na svojem vsakokratnem vzdolžnem koncu, gledano v smeri toka obdelave, zasnovano z ustrezno zaokrožitvijo ali posnetjem 17'.[0012] Said holding device 12 comprises a carrier 16 that is attached to said transverse carrier 13, and a sliding guide 17 that is suspended on the carrier 16, such that the sliding guide 17 is movable relative to the carrier 16. Said carrier 16 is essentially in a plane parallel to the plane of said transport device 2 or. the plane of said transport chains 2 '. Said sliding guide 17 on the carrier 16 is designed in such a way that the carrier 16 comprises at least one anchorage 18, preferably two anchorages 18, and that the slide guide comprises at least one anchorage 19, preferably two anchorages 19, the anchorages 18 of the carrier 16 being articulated connected to the anchorages 19 of the slide guide 17. In its neutral position, the slide guide 17 is arranged above the conveyor device 2 at a height less than the thickness of the workpiece 6. Said slide guide 17 is, at each respective longitudinal end, viewed in the direction of the workflow, designed with proper rounding or shot 17 '.

[0013] Ena od mogočih izvedb omenjenega obešenja oz. omenjene zgibne povezave predvideva, da sta nosilec 16 in drsno vodilo 17 medsebojno povezana s pomočjo togih palic 20, katerih vsaka je s svojim vsakokratnim koncem zgibno povezana z vsakokratnim parom pritrdišč 18; 19.[0013] One of the possible embodiments of said suspension or suspension. said articulated link means that the support 16 and the sliding guide 17 are interconnected by means of rigid rods 20, each of which is articulated with its respective end by a respective pair of anchorages 18; 19.

[0014] Nadaljnja mogoča izvedba omenjenega obešenja oz. omenjene zgibne povezave predvideva, da sta nosilec 16 in drsno vodilo 17 medsebojno povezana s pomočjo elastičnih sredstev 21, katerih vsako je s svojim vsakokratnim koncem povezano z vsakokratnim parom pritrdišč 18; 19. Po predlaganem izumu je omenjeno vsakokratno elastično sredstvo 21 izbrano kot vzdolžno intenzivna vzmet, ki je s svojim prvim koncem togo povezana s pritrdiščem 18 nosilca 16 in je s svojim drugim koncem togo povezana s pritrdiščem 19 drsnega vodila 17. Omenjena vzmet je lahko izbrana kot tlačna vijačna vzmet, upogibna vzmet in podobno.[0014] A further possible embodiment of said suspension or suspension. said articulated link means that the carrier 16 and the sliding guide 17 are interconnected by means of elastic means 21, each of which is connected to its respective end by a pair of anchorages 18; 19. According to the present invention, said respective elastic means 21 is selected as a longitudinally intense spring, which is rigidly connected to the anchorage 18 of the carrier 16 at its first end and rigidly connected to its second end to the anchorage 19 of the slide guide 17. Said spring may be selected such as pressure coil spring, bending spring and the like.

[0015] Z gonilom 10 kontinuirano gnana transportna naprava 2 z vgrajenimi sojemali 3 odvzame vsakokratni spodnji obdelovanec 6 iz zaloge, vsebovane v zalogovniku 5, in ga potiska proti in skozi vsakokratno obdelovalno postajo 7. Sojemala 3 prinesejo obdelovanec 6 najprej do vstopnega območja drsnega vodila 17 prve obdelovalne postaje 7. Ker je drsno vodilo 17 razporejeno nad transportno napravo 2 na manjši višini kot je debelina obdelovanca 6, slednji drsi po zaokrožitvi 17', pri čemer odmika drsno vodilo 17 v smeri toka obdelave. Ko je drsno vodilo 17 zadosti odmaknjeno (na sl. 4 predstavljeno s črtkano črto), zdrsne obdelovanec 6 pod drsno vodilo, ki ga bodisi zaradi lastne teže in/ali sile elastičnega sredstva 21 pritiska k transportni napravi 2. Posledično je obdelovanec 6 dovolj togo vpet, da ga obdelovalna enota 11 oz. krožna žaga 14 v prvi delovni postaji 7 obdela oz. obreže pod zahtevanim kotom. Ko je obdelovanec 6 obdelan oz. ko zapusti obdelovalno enoto 11 prve delovne postaje 7 ga omenjena sojemala 3 transportne naprave 2 potisnejo izpod območja drsnega vodila 17, ki posledično pade v smeri proti transportni napravi 2 nazaj v svoj nevtralni položaj. Sojemala 3 potisnejo obdelovance 6 proti drugi delovni postaji 7, kjer se opisani postopek ponovi tolikokrat zapored, kolikor delovnih postaj 7 obsega stroj po izumu.[0015] With gear unit 10, a continuously driven transport device 2 with embedded sockets 3 removes the lower workpiece 6 from the stock contained in the container 5 and pushes it towards and through the respective work station 7. The hooks 3 bring the workpiece 6 first to the inlet region of the slide guide 17 of the first machining station 7. Since the sliding guide 17 is arranged above the conveyor 2 at a lower height than the thickness of the workpiece 6, the latter slides after rounding 17 ', moving the sliding guide 17 in the direction of the workflow. When the slide 17 is sufficiently spaced (in Fig. 4 represented by the dashed line), the workpiece 6 slides under the slide guide, which, either due to its own weight and / or the force of the elastic means 21, presses against the transport device 2. Consequently, workpiece 6 is rigid enough. fastened to the processing unit 11 or. the circular saw 14 in the first workstation 7 processes or trims at the required angle. When the workpiece 6 is machined or. when it leaves the processing unit 11 of the first workstation 7, said clamps 3 of the conveyor device 2 push it below the region of the slide guide 17, which subsequently falls in the direction of the conveyor 2 back to its neutral position. The workpieces 3 push the workpieces 6 toward the second workstation 7, where the procedure described is repeated as many times as the workstations 7 comprise the machine according to the invention.

[0016] Zasnova držalne priprave 12 po izumu zagotavlja, da morebitno dimenzijsko odstopanje zaporednih obdelovancev 6 ne more vplivati na togost vpetja. S tem je zagotovljena visoko stopnja zanesljivosti delovanja stroja ne glede na dimenzijska odstopanja obdelovancev 6 v katerikoli njegovi prečni smeri. Dalje je na izstopnem koncu 8 stroja po izumu prigrajen zbiralnik 9 obdelanih obdelovancev 6, od koder jih pobira in zatem pakira na primer posluževalno osebje, robotska naprava in podobno.[0016] The design of the holding device 12 according to the invention ensures that any dimensional deviation of successive workpieces 6 cannot affect the rigidity of the clamp. This ensures a high degree of machine reliability regardless of the dimensional deviations of the workpiece 6 in any of its transverse directions. Further, at the outlet end 8 of the machine according to the invention, there is a collector 9 of machined workpieces 6, from which they are picked up and subsequently packed, for example, by the operating personnel, the robotic device and the like.
