The technical effect of the invention is that, with the simplicity of the device's construction, reliable guidance of sewn parts is achieved.

Description

Vynález ee týká zariadenia na vedenia šitých dielov, zvlášť časti zvršku při šiti mokasín.The invention relates to a device for guiding the sewn parts, in particular a part of the upper for sewing moccasins.

Pri zošivani epodnáho a vrchného dielu mokasíny sa okrem prevažne zauživanej technologie ručnáho šitia používajú tiež šijacie stroje. Zariadenia na vedenie šitých dielov u týchto strojov pozostávajú z prestavltelných dorazov slabo vodiacich valčekov, o ktorá aa z vonkajšej strany zošivaná diely opierajú. Nevýhodou takýchto konštrukcií ja nepřesná vedenie šitých dielov, takže pri opakovanom šiti je opakovaný steh našitý vedla prvého pevnostnáho stehu, čo je příčinou nízkej kvality výrobku. Ďalšou nevýhodou je nizka produktivita práce vzhladom na pomalý posuv dielov v snahe o čo najpresnejšie opakovaná šitia.In the sewing of the ephod and top of the moccasin, sewing machines are used in addition to the predominantly hand sewn technology. The devices for guiding the sewn parts in these machines consist of adjustable stops of the weakly guided rollers on which the and / or the sewn parts rest. A disadvantage of such constructions is the inaccurate guidance of the sewn parts, so that in the case of repeated sewing, the repeated stitch is sewn along the first strength stitch, which results in poor product quality. Another disadvantage is the low productivity of the work due to the slow movement of the parts in order to repeat the sutures as accurately as possible.

Uvádzaná nevýhody odstrašuje zariadenie na vedenie šitých dielov podlá vynálezu, kterého podstata epočiva v tom, že k upinaciemu telesu je pcostrednictvom čapu otočné připojená noená rameno, pevne spojená so stlpikom, ktorý je zverne spojený s vodiacim ráme* nom, na ktorom je otočná upravená vodlace koliesko, pričom čap a vodiace koliesko majú spoločnú oa otáčanla.The above-mentioned disadvantages are avoided by the device for guiding the sewn parts according to the invention, the essence of which is that the arm is pivotally connected to the clamping body by means of a pivot, rigidly connected to a post rigidly connected to the guide frame. the wheel and the pin and the guide wheel have a common and rotated joint.

Technický účinok vynálezu epočiva v tom, že pri jednoduchosti konštrukcie zariadenie se doeehuje spolehlivá vedenie šitých dielov.The technical effect of the invention is that in the simplicity of construction of the device reliable guidance of the sewn parts is achieved.

Přiklad vyhotovenia zariadenia podle vynálezu je achámatioky zobrazený na přiložených výkresoch, kde obr. 1 znázorňuje nárys zariadenie e čiastočným zobrazením Šitých dielov a rámu etroja a preetavitelným dorazem a obr. 2 znázorňuje půdorys tohoto zariadenie e vyobrazením jeho krajných polůh.An example of an embodiment of the device according to the invention is shown in the accompanying drawings in which: FIG. 1 shows a front view of the device e with a partial representation of the sewn parts and the machine frame and a removable stop, and FIG. 2 shows a plan view of this device by depicting its extreme positions.

K rámu 14 etroja je upínacími skrutkami 12. 13 preetavitelne pripewrená upinaoie teleeo £, v ktorom je zaliaovaná ložisko umožňujúce otáčanie čepu 7 e připevněným nosným ramenom 2. Kolmo k nosnému ramenu 2 Je připevněný atlpik £, ktoráho horný koniec je zverne spojený e vodiacim ramenom 4. Zverný apoj medzi vodlacim ramenom 4 a stlplkom £ je , zabezpečovaný ailou vyvodzovanou skrutkou 6. Polohu vodiaceho ramena 4 na stlpiku 3 možno takto v zvialom amere meniť. Na konci vodiaceho ramena 4 je otočné uložená vodiace kolieeko 5. časti zariadenia sú zmontovaná v jednej rovina, noaná rameno 2 a vodiace rameno 4 eú přitom vzájomne rovnoběžná. Vodiace kolieako 6 a čap 7 majú apoločnú oa χ otáčania. Zariadenie na vedenle šitých dielov je ešte doplněná preetavitelným dorazem 11 upevněným na platničke 16 rámu 14 stroje, V upinecom telese 1_ eú vytvořená drážky pre posuv vzhladom na upínacie skrutky 12. 13. člm aa umožňuje naetevovanie zariadenia v smere oei x.To the frame 14 of the machine, the clamping screws 12, 13 are removably fastened clamping body 8, in which a bearing enabling rotation of the pin 7e is attached by a fixed support arm 2. Perpendicular to the support arm 2 An atlpik 6 is fastened. 4. The clamping connection between the guiding arm 4 and the column 6 is provided by an aforementioned screw 6. The position of the guiding arm 4 on the column 3 can thus be varied in the vertical amera. At the end of the guiding arm 4 the guiding wheel 5 of the device is rotatably mounted. The parts of the device are assembled in one plane, the arm 2 and the guiding arm 4 eu being parallel to each other. The guide wheel 6 and the pin 7 have an apparent o and χ rotation. The device on the sewn parts is further complemented by a removable stop 11 mounted on the plate 16 of the machine frame 14. The grooves for displacement relative to the clamping screws 12, 13 are formed in the clamping body 7 and allow the device to be opened in the oe x direction.

Claims

An example of an embodiment of the device according to the invention is shown on the enclosed furnaces, where Fig. 1 shows the device elevation and a partial display of the sewn parts and frame of the machine by a stop and Fig. 2 shows the front view of this device and the illustration of its end poldh . A clamp 5 is attached to the frame 14 of the machine by the clamping screws 12, 13, in which a bearing is provided to allow rotation of the clamp 7 with a fixed arm 2. Perpendicular to the arm 2 An arm is fixed, which upper arm is attached to the arm. The guide arm 4 and the guide bar 4 are provided by the elongated guide screw 6. The position of the guide arm 4 on the tab 3 can thus be changed in this way. At the end of the guide arm 4 there is a rotatably mounted guide cradle 5 of the device and mounted in one plane, the worn arm 2 and the guide arm 4 are parallel to each other. The guide wheel 6 and pin 7 have an χ rotational axis. The device on the side panels is complemented by a removable stop 11 mounted on the plate 16 of the frame 14 of the machine. In the clamping body 1, grooves are provided for sliding on the clamping screws 12. 13. By means of an ea, the device can be fixed in the x. The equipment of the facility is naaledowná.
