(54) ЗЕВООБРАЗУЮЩЕЕ УСГЮЙСТВО(54) CULTIVATING USGY

Изобретение касаетс конструкции зевообразующего устройства дл круглой ткацкой машины со мнотими образованными одновременно волнистыми зевами, в пучности волн которых располагаетс по одному челноку и привод ремиз которого осуществл етс от двух укрепленных на средием приводном средстве раопределительных дисков с криволинейными пазами, в которые заход т закрепленные на шатунах направл ющие ролики и механизм передачи движени ремизкам.The invention relates to the design of a shedding device for a round weaving machine with many incorpore wavy pharynias formed simultaneously, in the antinodes of which there is one shuttle and the remise drive of which comes from two defining discs with curvilinear grooves, which are attached to the connecting rods guide rollers and a mechanism for transmitting movement to the shafts.

Однако трубчатые издели , вырабатьюаемые на таких устройствах, мотут иметь только полотн иое переплетение. Дл изготовлени трубчатых изделий с саржевьпм перюплетением требуютс сложные и дорогосто щие механизмы.However, tubular products produced on such devices may only have weaves. Complicated and expensive mechanisms are required to manufacture tubular products with twill twill.

С целью обеспечени возможности получени трубчатых изделий в саржевом переплетении в предлагаемом зевообразующем устройстве механизм передачи движени от привода к ремизкам вьшолнен в виде шестеренчато-реечной передачи, включающей две группы зубчатых реек, св занных при помощи шестерен, одна из которых соединена с направл ющими роликами, а друга с ремизками.In order to provide the possibility of obtaining tubular products in a twill weave in the proposed shedding device, the drive-to-helix transmission mechanism is implemented in the form of a gear-slatted transmission comprising two groups of gear racks connected with gears, one of which is connected to guide rollers, and a friend with remises.

На фиг. 1-3 изображено предложенное зевоо5разующее устройство.FIG. 1-3 depicts the proposed shedding device.

Привод зевосадбраззтащсгс устройства ос тцествл етс даумж распределкхельиыми дисками I и 2 е крзшолкнейными пазжж 3 и 4. На шатунах 5 и 6 закреплены ролики 7-10 йхо, в криволинейные лазы. При этом каждош криволгагейному пазу соподта ены два различных направл ющих ролика , которыге соеданены при помощи болтов 11 и 12 друг с другом и- соответствувмщц ® шатунами. Вьшолненные в ввде сферических шаршсоподошпНИКОВ направл ющие ролики 7 и 9 большего диаметра прилегают к внутрешшм направл ющим 13, 14, а ролики 8 и 10 с меньожм диаметром (вьшолненные точно так же как и ролики 7 и 9) прилегают только к внепшим направл ющим 15 и 16. ВысотаThe drive of the zevosadbrasztachtststsy device is equipped with a daumge distribution discs I and 2 with short collision pazzhzh 3 and 4. On rods 5 and 6 there are fixed rollers 7-10 iho, in curvilinear holes. At the same time, each different curvilga-ny groove is accompanied by two different guide rollers, which are connected with the help of bolts 11 and 12 with each other and with corresponding rods. The larger-diameter guide rollers 7 and 9, which are made in a vvde of spherical scores of the supporting heads, are adjacent to the inner rails 13, 14, and the 8 and 10 rollers with a smaller diameter (executed exactly the same as the rollers 7 and 9) are adjacent only to the outer ones 15 and 16. Height

Claims

the perimeter of the teeth 20, which are engaged with the gear 22 mounted on the drive shaft 21, the simultaneous rotation of the rotating gear of the shuttles. Both crankshaft grooves 3 and 4 are con ﬁ gured and, through 180 °, the interior radnuses are different, and are also fixed on the housing under shshka 18 with shifted to one relative to the other. The connecting rods 5 and b are located in the directions of 23 n 24, which are mounted on one end of the toothed racks 25 n 26, which engage with secured pin on the individual rollers 27 and 28 of the gear wheels 29 and 30 in the housing 31 of the transmission mechanism from the drive to remizkam. On the roller 28, another gear wheel 32 is reinforced, which works in conjunction with the end of the head made in the form of a toothed rack 33 and which also moves vertically with the guide rod 34. This guide rod is positioned between the second and third rods 35 and 36 shafts and is provided with a rotating gear wheel 37, the second one is engaged on both sides with the heads of both rods 35 and 36 of shafts made in the form of gear racks 38 and 39. The rods 35, 36, 40, as well as the guide rod 34, are moved in height to the housing of the guide 41 of the mechanism for transmitting movement from straight to helix. The shafts 42 - 44 are strengthened over the rods 35, 36, 40. The operation of the described shedding device is as follows. In the position shown in FIG. 2 and 3, the first shaft of the shank 40 and, therefore, the shim 42 is in the position of the upper pharynx so that all warp threads (not shown in the drawing) form the upper branch of the pharynx. All diverted from shafts 43, 44, the main thread (not shown) image from the lower branch of the pharynx. Thus, when the weft yarn is first laid, the first main thread is connected in height to the weave patterns. The next weft yarn to achieve a twill weave, the second main thread must be connected in height and the next weave third third thread should be connected in height to the weave pattern. This is achieved by a mechanism for transferring motion from the drive to the shafts. The upper position of the shaft of the shim 40 with the shim 42 (see Figs. 2 and 3) is achieved by extending the lower flange 6, as a result of which the shank 40 of the gear wheel 29 with the shaft 28 rotates in one direction. While the gear 29 mounted on the shaft 28 lifts the rod shafts 40. As soon as the lower shatun 6 leaves the belt-raising mechanism, the shaft 28 will rotate in the other direction, as a result of which the shim rod 40 will move down again. At the same time, the gear 32 engages with the gear 33 and lifts the pick bar 34. The gear 37 rolls along the locked gear rack 39 and lifts the second hem 35 with the gear bar 38. in the upper pozcin. Further, the gear 5 is displaced by a curvilinear groove 3 to the heald mechanism. In doing so, the shaft 27 of the gear rack 25 and the gear wheel 30 rotates, as a result of which the gear wheel 45, which sits on the shaft 27, lifts the shaft 36 of the shim. At the same time, the pin 35 with the hem 43 is moved down by the toothed wheel 37. Thus, the last necessary twill weave is achieved. During these operations, the distributor disks 1, 2 turn on n, as soon as their curved grooves 3, 4 begin to cross each other, both connecting rods 5 and 6 move oppositely and the operation is repeated in reverse order. Claim 1. The sieve-forming device for multi-seam round weaving machine containing heald blades is driven by two spreading discs with curvilinear grooves fixed on connecting rods of guide rollers mounted on middle driving gear, and shafts, characterized in that, in order to provide the possibility of obtaining tubular products in twill weave, the mechanism for transferring movement from drive to shafts is made in the form of pinion gears, including two groups of gear racks, connected by means of gears, one of which is connected to the guide rollers, and the other one is connected to shims.

2. The device according to claim 1, characterized in that the gear racks of one of the groups of the rack and pinion gear are made at the free ends of the rods, each rake of one group interacting with two of the other rails.
