Abstract

The invention relates to a textile machinery industry and is intended for use on a rotary helix-type rotary helix and improves serviceability by facilitating the "fold" tracing operation. The search for "fold" is performed by rotating the main shaft of the carriage one turn back. The reading of the program is carried out with two needles 1 and 2 and is transmitted to the actuating elements by means of the summing lever 3. The needle 1 reads the signal of the previous one, and the needle 2 reads the signal of the subsequent given shedding cycle. 2 Il.

Description

In Table 2, the variable vo denotes the state of the link 7 in the previous zero-generation cycle. and variable vi is the state of the same link in the first shedding cycle. The variable wi denotes the effect exerted on the input element of the 5th mechanism. When the knife is pushed onto the pusher 5 directed downwards along the arrow r, the link 7 moves to the left and takes the opposite position, the arrow d. The link 6 passes through the lower position, for example, under the influence of inertia force. The pusher 5 returns to its upper position under the action of a spring,

From Table 2 it follows that in order to preserve the previous state of vo link 7 in the next 5

five

In Table 3, the variable xi denotes the state of the lever 11 in the previous, zero, shedding cycle, and the variable X2, the state of the same lever in the next, first cycle. The variable vi denotes the effect exerted on the eccentric from the side of the carrier 9. As the carrier rotates (during one cycle of shedding), the eccentric 10 rotates, moving lever 11 from one end position to another.

From Table 3 it follows that in order to preserve the previous state of the lever 11. obtained by him in the zero cycle of sheddings, the eccentric 10 must be in a state of rest. , a, pos. 1 and 3, and to change the state of the lever 11 to the opposite, the eccentric should rotate, X2-X1, pos.2 and 4.

Thus, for the first shedding cycle, the logical function of the states

Even 11 is described by a function (see Formula 6 and Table 3) ",

X2 XW1 + X1V1. (9)

From formula (9), it follows that in the third control cycle, the new state of link 11 is determined (after reinstallation) by a logical summation of the state of link 9, which received a command from switch 7 and eccentric state 10, which retained its state from the previous control cycle .

By substituting the known value of wi into formula (8), see formula (1), and calculated value vi into formula (9), we obtain the state of output links 7 and 11 depending on the elements ao and az of a given rapport expressed by functions;

vi aia2 + aia2,, which corresponds to the values given in the diagram of FIG. 2.

Due to the fact that the structure of the management team is formed taking into account the previous and future conditions of remise, it becomes possible to coordinate the shedding program with the pattern on the fabric and to search for the time by simply rotating the main shaft of the carriage one turn back, which greatly improves serviceability.
