DE1144629B - Pot spinning machine or twisting machine with a spinning pot that is open at the top, in which the thread stored as a cake in the pot is wrapped around a sleeve that has been introduced into the pot - Google Patents

Description

The invention relates to a pot spinning or twisting machine with a spinning pot that is open at the top which the thread deposited as a cake in the pot was brought into the pot in place of the thread guide Sleeve is wrapped.

In a known pot spinning machine, a thread guide and a thread tensioner are attached to the Coupled bobbin, in such a way that the thread guide by means of a manually operated lever from the The spinning pot can be taken and placed in the spinning pot with the thread over the edge of the The pot is cut off when the bobbin carrier is inserted into the pot and the thread by means of the thread tensioner is tensioned.

The loose, cut end of the thread that hangs down from the drafting system should then be countered again the inner wall of the pot can be brought to resume spinning. This is because of this achieves that the thread guide is coupled to a compressed air line when it enters the pot. This takes place when the thread is already in motion, whereupon the air supply is cut off again will.

In practice, however, such a device has several disadvantages.

First, the construction is rather complicated and due to the use of different ones Pivot points for thread guides, bobbin carriers, etc. prone to failure when worn; because thread guides and Coil carriers here each have their own pivot point, since they are two separate devices, and these devices are connected by means of a connecting rod for simultaneous movement to enable.

Another disadvantage is that with this device it is not possible to obtain an optimal spinning pot filling to get, so a spinning pot filling, in which after winding the bobbin straight and vertically can be taken from the pot, as the coil carrier is removed from the pot here while he rotates around its pivot point after winding.

Another disadvantage is that the thread can break when the sleeve is inserted into the pot.

Namely, the thread breaks off while it is being tensioned by means of the thread tensioner, the broken one Because of this tension, the thread slides out of the thread guide fairly easily, which is further facilitated by the tendency of the thread to pucker from the twist introduced.

In addition, a separate compressed air line is required, with which the cut thread end again with the inner wall of the pot in contact with the pot spinning machine or twisting machine

The operation of this spinning machine also has a disadvantage in terms of changing the bobbins, because the full bobbin is always in the direction of the spinning machine, i.e. from front to back, from the bobbin carrier to be removed for attaching a new sleeve, for which very little space is available.

After tearing off, the free thread end remains in contact with the pot, so that the spinning takes place immediately can take place on it.

The full bobbin can easily be removed in the direction of the arrow (i.e. from the front to the front rear).

According to Fig. 2, the processes run as follows when the pot is full:

1. An auxiliary shaft 11 is rotated from position 0 to position I, which z. B. by means of a lever 12 can happen. By rotating this auxiliary shaft, the control shaft 14 by means of a gear 13 lifted, whereby the thread guide 4 is removed from the pot 1. This twist is also used to control the control shaft with thread guide 4, bobbin carrier 3 and thread tensioner 5 turn by 90 °. For this purpose, a shock cam 15 arranged on the shaft 14 presses switch 16, causing the rotation of the shaft and the drafting system and the changing mechanism together be turned off (not shown); the thread reserve increases with the rotation provided.

2. Lever 12 is turned counterclockwise from position I to position II; the coil carrier with sleeve 3 is placed in the pot 1, it is then wrapped around the sleeve 3.

3. Lever 12 is turned clockwise from position II to position III; the bobbin with the full bobbin is lifted and brought out of the pot; at the end of the lifting the bobbin carrier and the thread guide are rotated by 90 ° by the impact cam 15 'against the switch 16 is pressed.

4. Lever 12 is turned counterclockwise from position III to position IV; the thread guide 4 is returned to pot 1; at the end of this movement, the thread is torn off at the edge of the pot, as indicated; to at the same time the drafting system and the changing mechanism, which in the meantime turned back, put into operation.

The interaction of the impact cams 15 and 15 'with the switch 16 is explained in FIGS. 2A to 2D:

When the control shaft 14 is raised, the cam pushes under the nose 16 α of the switch 16, which is pivotable about the axis 16 c, and puts it to the right (FIG. 2B) while rotating the shaft 14 from the initial position (FIG. 2A) until the End position at stop 16 e (Fig. 2C) is reached.

45 is lowered, the control shaft 14 (Fig. 2D), the cam 15 presses' by impact on the nose 16 b the switch to the side; However, this remains in the position shown in FIG. 2D and can now be actuated by the cam 15 'the next time the control shaft 14 is raised, whereby the reverse rotation of the control shaft is effected at the same time.
