Description

The existing constructions of devices for changing reels to conventional vaters with annular strips moving along the axes of the spindles are complex, since their organs, which are removed from the spindles of the reel, have to undergo quite a variety of movements during the removal operation.

The design of the proposed device is also simpler than the existing ones. It is designed for a pre-reconstructed vater equipped with fixed annular strips and spindles mounted obliquely during removal, and has the distinctive feature that it uses bouncers for reel-shaped reels mounted in guides and displaced reciprocatingly with non-fixed and inclined non-spars for removing and dropping reels from them, for example, onto a discharge conveyor.

The drawing shows a side view of an exemplary form of the device for the water plate, previously reconstructed in the direction noted above.

The spindles are rotated from the leading drum 4 by means of the guide drum 5 and the guide and tension blocks 6. The guide and tension blocks 6 are mounted on the cross link 2, at the ends of which the shafts 3 are placed, the holders 7 of the spindles. The movement of link 2 in the vertical plane is carried out by means of chains 23 slung over blocks 12.

Blocks 12 are placed on shafts associated with a winding mechanism. In order to protect the communication 2 from lateral movement, each of the two shafts 3 is placed in bearings 8 sliding in the vertical grooves of the intermediate frame 10.

Since, simultaneously with the movement of the spindles, the guide blocks b also move, the length of the tape and the direction of the rolling part of the tape remain constant during the operation of the water block.

The device for changing reels contains the following basic elements:

1) colliders 18 for reels, mounted in guides 9 and moved reciprocatingly from gears 19,

2) holders 11 for empty reels,

3) guides 13 for full bobbins,

4) 22 conveyors for allotment of 1n reels.

5) thread guides 21 and 14.

At the beginning of the pickup operation, the link 2 is in the upper position shown by a dotted line, and the spindle, therefore, in the top position A. As the spindle picks up, the spindle is gradually lowered so that by the end of the pickup the yarn is wound onto the upper ends of the reels. The spindle is lowered below the level of the ring bar to occupy the removal of the spindle and occupy the B rise. This occurs at the same time as the angle of the thread guides 14 is rotated. When rotated from position B to position C, the spindles simultaneously enter the forks of the knocking pin 18, which are located at the moment of rotation of the spindles in the lower position and

By turning the gears 19, the colliders 18 are moved to the upper position, thereby removing the accumulated spools of faith gene. Simultaneously with the movement of the colliders 18 and the upper position, the thread is further loosened by the thread guide 14, which in this case is moved from position S to position a.

Reels with yarn, shifted to the upper position, enter the guides 13, and then, when the latter rotates from the position to position in, the reels with the yarn fall onto the conveyors 22, located along the entire length of the watermark. During removal

The conveyors are stopped and come into operation only after the removal of the removal, transferring the removed reels from the yarn into the drawers installed at the end part of the windrow.

Reel threads; - located on the conveyors 22, are cut off by scissors 20, such as those used on the Japanese Hakoba bobbin winder, for which the lower thread guides 21 are transferred from position f; in position d, feed all the threads to the scissors 20.

Further, all the spindle of the water switch is transferred from position C to position D, stopping against holders AND empty reels. When opening the covers 17 of the holders 11 with the levers 16 mounted on the shaft 15, the reels fall onto the spindles, at the same time slipping along the threads and clamping them between the reels and spindles in the lower position. In order to grip the threads, the reels have radial slots in the lower part. After landing, the spindle spools are shifted from position D to position B, and empty spools are deposited on them manually or mechanically. The spindles are then raised to the initial position A. The excessive length of the filaments during lifting is selected by the yarn feeders 14, which are moved in this case from position a to to position c. The reverse movement of the thread guides 14 from position B to position A takes place at the time the vater starts up.

Subject invention

A device for changing bobbins to a watering machine with fixed annular strips and spindles mounted obliquely at removal, characterized by the use of knobs 18 mounted in guides 9 and moved reciprocatingly when spindles are lowered and inclined mounted to remove bobbins and drop them onto the conveyor belt.
