Description

Изобретение относитс к текстильной промышленности, а более iконкретно - к бобино- и шпуледер:жател м , обеспечиваюцим фиксацию, центрирование и зажим бобины, и может быть использовано на всех тексгильных машинах.The invention relates to the textile industry, and more specifically, to bobbin and shpuleder: feeders, which ensure fixation, centering and clamping of the reel, and can be used on all textile machines.

Известен бобинодержатель, содержащий две обоймы, жестко смонтированные на концах вала и соединенные между собой продольными стержн ми , диски, шарнирно установленные в обоймах, и зажимные элементы, вьшолненные в виде диад, одно звено .каждой из которых несет фрикционные накладки и свободным концом шарнирно смонтировано на обойме, а другие свободным концом 1аарнирно смонтировано на соответствующем диске 1.Known bobbin holder containing two clips rigidly mounted at the ends of the shaft and interconnected by longitudinal rods, discs pivotally mounted in the cages, and clamping elements, executed in the form of dyads, one link. Each of which carries friction linings and the free end of the pivotally mounted on the holder, and the other free end 1aarniarno mounted on the corresponding disk 1.

Однако известное устройство не обеспечивает центрирование бобины с высокой точностью и не позвол ет отводить зажимные колодки от бобины перед ее съемом и надеванием.However, the known device does not provide centering of the reel with high accuracy and does not allow to remove the clamping pads from the reel before it is removed and put on.

Цель изобретени - повышение надежности работы устройства.The purpose of the invention is to increase the reliability of the device.

Поставленна цель достигаетс тем, (ЧТО бобинодержатель, содержащий две обоймы, жестко смонтированные наThe goal is achieved by the fact that a cobbling holder containing two clips rigidly mounted on

концах вала и соединенные между собой продольными стержн ми, диски, шарнирно установленные в обоймах, и зажимные элементы, выполненные в виде диад, одно звено каждой из которых несет фрикционные наклгшки и свободным концом шарнирно смонтировано на обойме, а другое свободньам концом шарнирно смонтировано на соответствуквдем дис10 ке, дополнительно имеет втулку по меньшей мере с одним винтовым пазом на ее боковой поверхности шарнирно, смонтированную на валу и жестко соединенную с торцами дисков, а вал shaft ends and interconnected longitudinal rods, discs pivotally mounted in cages, and clamping elements made in the form of dyads, one link of each of which carries friction clips and a free end pivotally mounted on the cage, and the other end is pivotally mounted on a corresponding end The disk additionally has a sleeve with at least one screw groove on its side surface pivotally mounted on the shaft and rigidly connected to the ends of the discs, and the shaft

15 имеет осевое отверстие со смонтированным в нем подпружиненным штоком, несущим жестко закрепленньй штифт, и радиальный паз, выполненный напротив винтового паза втулки дл прохо20 да штифта, при этом фрикционные накладки жестко установлены на соответствующих 3 вень х диад,15 has an axial bore with a spring-loaded rod mounted in it, carrying a rigidly fixed pin, and a radial groove made opposite to the screw groove of the sleeve for passing through the pin, while the friction linings are rigidly mounted on the corresponding 3 diameters of the dyads,

Claims

30 to 2, rigidly mounted at the ends, shaft 3, and discs. 4 and 5 pivotally mounted in the clips. The sleeves 1 and 2 are interconnected by longitudinal rods 6. Each clamping element of the bobbin holder is made in the form of a dyad, consisting of pivotally connected rods 7 and 8, and a friction lining 9 fixed on the link 7 of the dyad. The link 7 of each dyad is pivotally connected with the corresponding yoke, and the link 8 with the corresponding disk. The ends of the disks 4 and 5 are rigidly connected to each other by means of a sleeve 10 pivotally mounted on the shaft 3 and having at least one helical groove 11 on the side surface The shaft 3 has an axial bore 12 with a spring-loaded rod 13 mounted therein, carrying a rigidly fixed pin 14. The shaft 3 also has a radial groove 15 which is opposite the screw groove 11 of the bushing 10 so as to allow the pin 14 to pass, and spring 16. The device operates as follows. Before installing the reels, the rod 13 is forcibly moved to the left. At that, the pin 14 rotates the sleeve 10 and the disks 4 and 5 clockwise, and the friction linings 9 by moving the links 7 and 8 diades are recessed into the annular grooves of the sleeves. it until it stops, and release the rod 13, which moves to the right by turning the sleeve 10 and the disks 4 and 5 counterclockwise. All six friction linings 9 are moved to the working position, ensuring accurate centering of the reel and varying the diameter of the bore. When the bobbin holder rotates, the friction lining and the link of the dyad under the action of centrifugal forces tend to move away from the axis of rotation of the shaft 3, as a result, the pin 14 is unloaded, the spring 16 moves the rod 13 to the right, increasing the retaining force of the reel and does not disturb the centering accuracy. If the angle of elevation of the screw groove 11 is less than the angle of the friction, then any radial force acting on the friction lining will not cause the latter to move to the axis of the bobbin holder. To remove the bobbin from the bobbin holder, it is necessary to forcibly move the rod 13 to the left. The proposed bobbin holder allows increasing equipment productivity, as well as improving the quality of the thread and working conditions. "Claims of the invention: A coil holder containing two clips rigidly mounted at the ends of the shaft and interconnected by longitudinal rods, discs pivotally mounted in the cages, and clamping elements made in the form of dyads, one link of each of which carries friction linings and the free end of the hinge mounted on the holder, and the other with a free end pivotally mounted on a corresponding disk, characterized in that, in order to increase the reliability of operation, it has a sleeve with at least one screw groove on its b surface hinged on the shaft and rigidly connected to the ends of the discs, and the shaft has an axial bore with a spring-loaded Rod mounted in it carrying a rigidly fixed pin, and a radial groove made opposite to the screw groove of the bushing for the passage of the pin, while the friction lining is installed on the corresponding links of x dyads. - Sources of information taken into consideration during the examination 1.
