The invention relates to the textile industry and can be used for the automated removal of accumulated materials and the donning of empty spools on a roving frame for flax production.

The purpose of the invention is to simplify the design and reduce the time to replace the rollers.

FIG. 1 shows a general diagram of a roving frame with a device at the time of changing coils in FIG. 2 - the same, with the lowest position.

the carriages of the machine when operating coils in FIG. 3 - the same, with the extreme upper positions of the carriage of the machine when the coils are produced in figure 4 - section aa in figure 1 in figure 5; section bb in figure 2; figure 6 - section bb In fig.Z; in fig. 7 is a view of FIG. one; in fig. 8 - gripping chain and guide with holder; figure 9 - section dd in fig. eight.

The device contains an endless guide mounted on the frame 1 with racks 2 of the roving machine, both straight lines of which are located along the machine one above the other and with at least two connectors 3 on the end sections of the upper branch 4. The top branch 4 of the guide is placed on electromagnetic locks 5, which are placed on the uprights 2 with the possibility of vertical movement together with the carriage 6 of the machine and fixing it on the uprights with the help of the lock 7 (Fig. 4-6).

The upper branch 4 of the guide has the ability to connect to the fixed part 8 of the guide by means of clamps 9 and electromagnetic locks 10.

On the guide, the holders 12 of the coils 13 are made using rollers 11, made with coaxially disposed spindles 14 with undercuts 15 through holes 16 for their passage. The number of holders 12 is twice the number of coils produced on the machine. Coaxially spindles on the top carriage of the machine are equipped with hanging flyers 17.

20 two infinite flexible traction elements are placed, which are chains 21, enveloping sprockets 22 fixed on shafts 23 mounted in brackets 24 attached to frame 1 (Fig. 7). The chains are driven from the drive 25 or from the main drive of the machine (not shown).

Chains have grippers 26, the number of which is equal to the number of holders 12.

The device works as follows.

During the development of the coils, the upper branch 4 of the guide is disconnected from its fixed part and placed together with the holders 12 on the carriage 6 of the machine. After the coils have been developed, the roving machine stops at that moment when the carriage 6 (Figs. 3 and 6) is in the upper position. Then, two or three turns of the roving are rolled out from the coils in order to create a reserve of the roving to ensure the subsequent earnings and the rolls 17 are turned to the removal position with the solution across the machine. Further, electromagnetic locks 5 and 10 are included (Figs. 1 and 4). Electro-magnetic locks 10 are connected by clamps 9 to the upper branch 4 of the guide with the fixed part 8. Electromagnetic locks 5, on which the mobile branch 4 is attached, guides 7 to prevent its bending, using clamps 7 are clamped on the vertical racks 2. In this position, the clamps 26 (Figs. 4, 8 and 9) of the endless chains 21 are engaged with the rollers 11 by the carriers 12 of the coils 13. Thereafter, the carriage 6 is moved to its lowest position (Figs. 1 and 4). As the carriage 6 is lowered, the coil 13 is lowered into the holders 12 and out of engagement with the sub-coil 15 spindles 14. Then the chains 21 are brought into motion, which by the grips 26 lead and the holders 12 with the coils 13 follow the endless guide to the ejection unit 18 . Simultaneously p. on the opposite side, the grips 26 in the direction of the empty coil supplying unit 19 are removed free space

the chains are disconnected and the holders with empty coils are installed coaxially with the spindles 14, with the pitch of the holders and grippers corresponding to the spindle pitch. In the next stage, the carriage 6 rises to the upper position, e (Figs. 3, 6) and the spindle 14 with the undercuts 15, the passage through the apertures of the holders, enter the apertures of the coil trunks, and parasitize them above the holders. Further, the electromagnetic locks 5 and 10 are disconnected and their clamps 7 and 9, returning to the initial position, disconnect the upper branch and the fixed part of the guide. After disconnection, the upper branch of the guide is lowered onto the carriage 6 due to its own weight. Then the drive of the spindles of the carriage 6 and the flyers is turned on and the winding process begins. In the process of winding, the upper part 4 of the guide with holders reciprocates along with the carriage 6. After the winding is completed, the cycle of operation of the device for removing the coils is repeated.

The proposed device has a simpler design and allows reducing the time for changing coils by reducing the number of operations to bring the elements of the device into the working position and combining the removal of the developed coils with the installation of empty coils.
