Abstract

The invention relates to the textile industry — to the combed mechanisms of the devices — and allows for increasing the reliability of the operation of the mechanism by ensuring the stable position of the combed slats when they are transferred from one screw to another. The mechanism contains working and idle worms for moving the combed strips along the guide tracks along the field and cams for converting the combed strips from single worms to others. At both ends of the screws, spring-loaded clamping guides and pushing strips are installed in pairs, which are mounted on the axles and can be turned in the direction perpendicular to the ends of the screws. The axis of rotation of the pushing bar of each pair is placed on the side of the receiving combed bar of the screw, and the axis of rotation of the guide bar is placed on the side of the other screw. The strings of each pair of hinges are free from each other. The pushing bar is installed with the possibility of forming a working surface with a lead-in part of the screw narrowing the gap in the direction of movement of the combed bar. 3 il. i SL

Description

The invention relates to the textile industry and can be used in combed exhaust devices for tape and similar machines.

The aim of the invention is to increase the reliability of the mechanism by ensuring the stable position of the combed arms when they are transferred from one screw to another.

Figure 1 shows the combed mechanism, a longitudinal section, at the time of the start of the entry of the comb tail of the comb into the lead-in part of the screw; Fig. 2 is the same at the moment when the entrance of the tail of the combed bar ends; fig.Z - combed mechanism, a cross-section from the ends of the screws,

The combing mechanism contains horizontally mounted workers 1 and idle 2 worms for horizontal movement of combed strips 4 and cams 5 in order to transfer strips A from one cam to another (FIG. 3),

At both ends of the screws, the spring guides 8 and the pushing 9 bars, which are spring-loaded with springs 6 and 7, are installed in pairs, which can be rotated in the direction perpendicular to the ends of the screws. The axis 10 of the pushing bar 9 of each pair is placed on the side of the receiving combed bar screw (in FIG. 1 the operating screw), and the axis 11 of the guide bar 8 is on the side of the other screw. The slats 8 and 9 are articulated by means of the finger 12 and the slits 13 are connected with free ends to one another.

The pushing bar 9 is installed with the possibility of forming the working surface 14 with the lead-in part 15 of the screw narrowing the gap 16 in the direction of movement of the combed bar. In the process of operation of the combed mechanism, the combed bars 4 enter the movement zone of the fiber product being pulled out - horizontally working worms 1, and then go out of this zone and move in the opposite direction in idle worms.2,

Under the action of the rotating cams 5, the comb-strips 4 pass a gap between the end of the lower track 3 and the guide bar 8, pressing the latter. Plank 8 with a finger 12 acts on the pushing bar 9, which, also pressed to the left, opens the entrance to the tail of the combed bar in the cutting of the screw 1, while the working surface 14 of the bar 9, creating a slot with the lead-in part of the screw , guaranteeing tight control over the movement of combed planks at the initial moment of entering the cutting of screws. Upon further movement, the comb bar passes the end of the lower track 3 and the bar 8 moves to the right, dragging the bar 9, which, ahead of the guide bar 8, starts pushing the back part of the shank to the screw thread, thus closing the comb in

thread worm ka.

Claims (1)

This combed mechanism allows rigid control of the vertical movement of the combed strips in all areas of their movement, which excludes cases of striking of the combed strips and jamming of the mechanism, which increases the reliability of the combed mechanism and the mask as a whole. Invention Formula Combed mechanism of a textile machine, containing workers and hollow worms for moving the combed strips along guide rails along a field, cams for translation combed strips from one screw to another and located in pairs at both ends of the screws of spring-loaded pressure guides and pushing strips mounted at one end on the axles with the possibility of rotation in the direction of the ends of the screws, which is characterized by the fact that, in order to increase the reliability of the mechanism by ensuring a stable position of the combed bars when they are transferred from one screw to another, the axis of rotation of the pushing bar each the pair is placed on the side of the host of the combed strips of the screw, and the axis of rotation of the guide bar is from the side of the other screw, while the pushing and guiding bars are pivotally connected by free ends to one another, and the pushing bar installed with the possibility of forming a working surface with a lead-in part of the screw, which narrows in the direction of movement of the combed backlash.
