Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spinning machine of the type described in the superordinate concept of claim 1.

[0002]

2. Description of the Prior Art A spinning machine of this type is known from British Patent No. 982604 as a ring spinning machine. The collector for the exhaust of the spinning station is designed as a passage, which passes the exhaust through a filter to a ventilator which ensures the negative pressure required in the suction device.

In the above-mentioned specification, the spinning point is partially shielded from another spinning point by the partition wall of the casing, but in this case the casing only partially surrounds the spinning point and is at least completely opened upwards. ing. As a result, on one side, the spinning points are not completely shielded from the adjacent spinning points, so that especially in the event of thread breakage, the yarn parts reach the adjacent spinning points and likewise cause thread breakage there. In addition, the position and arrangement of the exhaust openings are inadequate, a relatively high ventilator output is required and the heat output from the spinning station is also defective.

[0004]

SUMMARY OF THE INVENTION The object of the invention is to avoid the disadvantages of the prior art systems and to ensure that the spinning machine with a suction device is fluff and heat resistant with a very low negative pressure and a low ventilator output. It is an improvement to ensure that the yarn can be discharged and in particular if a yarn break occurs, the obstacles to the adjacent spinning points are avoided.

[0005]

According to the present invention, the above-mentioned problems have been solved by the constitution described in the characterizing part of claim 1.

[0006]

A wide range of casings with chambers located above and below the yarn guides, which are effectively closed by a cover at the top and a bottom at the bottom, makes it possible, on the one hand, to ensure that the adjacent spinning stations are completely closed. On the one hand, they are shielded from the other and, on the other hand, in cooperation with the exhaust openings in the respective chambers, air is sucked into the chamber from above and below through openings in the cover or bottom and into the exhaust openings Such a ventilation effect is produced through the spinning points forming the yarn balloon.

In this case, the ventilator is virtually all that is needed to expel the air in the collector. This significantly reduces the required ventilator output,
This is important in order to reliably suck out the fluff generated at the spinning location, especially when yarn breakage occurs. At the same time, the heat generated at the spinning point is also discharged.

Advantageous configurations of the invention are described in the other claims. A significant improvement in the desired airflow guidance is obtained by means of an intermediate bottom with an opening for the thread balloon in the upper chamber, which intermediate bottom forms a baffle for the airflow which is arranged substantially horizontally.

Still another claim describes a device which serves to further improve the effect of the description and to improve the heat dissipation. A particularly advantageous configuration has the following features. A rectangular chamber with eccentrically arranged spinning points, a horizontal baffle for further division of the upper chamber, a cover of the chamber and a best-fitted exhaust opening in the bottom. An extensive cover of the vertical spinning points, an extension of the lower chamber, an additional vertical baffle and air guidance to the exhaust openings further improve and optimize the abovementioned features.

[0010]

1 shows a part of a spinning machine with a suction device 18 and the elements of a spinning station 10 with a spindle 11 drivably mounted on a stationary spindle rail 6. Furthermore, FIG. 1 shows four spinning stations with a substantially horizontal yarn guide 16.

In the case of a ring spinning machine, the thread guide 16 is located in a so-called ring rail, to which a ring 9 is attached for each spinning station 10. On the ring, the traveler 17 guides the yarn 12, which is wound on the spindle 11.

The casing 19 has two chambers fixed to the thread guide 16 of the ring rail and moving with it. That is, a first chamber 20 arranged below the thread guide 16 with an opening 23 for the spindle 11 in the bottom bottom and an upper cover 32.
Thread guide 1 with opening 33 for thread balloon 13 in it
6 and a second chamber 30 disposed on the upper side. Both chambers have a respective exhaust opening 21, 31 arranged at the height of the thread guide 16.

In this case, the ring rail is divided in the horizontal direction, and the upper cover 32 and the lower bottom 2 are divided.
2 perfectly closes the casing on the lower and upper sides. By this and by virtue of the configuration of the openings 23, 33 and by utilizing the rotation of the spinning points forming the yarn balloon 13, a ventilation effect is produced in the chambers 20, 30.

In this case, ambient air is drawn into the chambers 20, 30 from above via a suitably designed opening 33 and from below via the opening 23 near the spindle 11 or the thread balloon 13 and from the spindle axis A. It is pushed again into the collector 14 via the exhaust openings 21, 31 which are located at a sufficient distance. Evacuation of air in collector 14 is aided by a relatively low power ventilator (not shown).

The energy used to rotate the spindle 11 according to the inventive design of the casing is therefore additionally utilized to suck out the fluff as best as possible and to dissipate the heat generated at the spinning station 10. It

In this embodiment and in FIGS. 2 and 3,
A balloon restriction ring 15 is fitted in the cover 32 near the upper casing closure. This also makes the required opening 33 for the thread balloon 13 smaller.
Advantageously, the balloon restriction ring 15 or the thread balloon 1
An annular gap 50 having a width of several millimeters, for example, 4 to 10 millimeters, is opened between 3 and the limiting portion of the opening 33. In this case, due to the movement of the thread 12 or the thread balloon 13, air is additionally drawn into the second chamber 30 via the gap 50.

In order to control the function of the traveler 17 on the ring 9, when using a traveler sensor 57 which continuously moves from one spinning point 10 to the next, the intermediate between the spinning points. Within the wall 44 is provided the smallest possible opening 51 for passing the traveler sensor. It is advantageous if the traveler sensor is guided in a separate tunnel 52, which can penetrate the second chamber 30 and thus completely seal adjacent spinning points to one another.

2 and 3, the spinning station 10 with the casing 19 is shown in side and plan views.
Both the lower and upper chambers 20, 30 of the ring rail or the bottom 22 and the cover 32 have a rectangular base surface. The chamber is formed by a front wall 42, a back wall 43 and a side wall 44 which also forms an intermediate wall for the adjacent spinning station 10.

The length S2 of the side wall 44 is preferably greater than the length S1 of the back wall 43 and the front wall 42, which is equal to the spacing between adjacent spinning stations 10. The length S2 is preferably at least 1.2 times, preferably 1.5 to 2 times the length S1.
Chambers 20, 30 that are significantly different from the concentric annular shape
With said geometry of the air flow is controlled in the desired manner. That is, a high air velocity is generated in the spindle 11 and the yarn balloon 13 as shown by the arrow,
This air velocity decreases as the distance from the spindle axis A increases and is additionally dammed at the corners of the chamber.

Since the exhaust openings 21 and 31 are provided at the height of the thread guide or the ring rail, the ambient air in the upper chamber is drawn along the thread balloon 13 to the ring rail and discharged. On the other hand, in a similar manner, the ambient air in the lower chamber and thus also the heat generated at the spinning point is sucked along the spindle to the ring rail and discharged there.

Since the chambers 20 and 30 move up and down together with the ring rail over the travel range HH, the casing height H is chosen to be relatively large, that is to say the casing height H is between 70 and 90 of the travel range HH. It is a percentage.

As also shown in the embodiment of FIGS. 4 and 5, in this case the height of the lower chamber is limited approximately by the given space up to the spindle rail 6. The height H2 of the upper chamber is limited by the upper space provided up to the thread eye 7.

Normally, the height H2 of the upper chamber 30 is selected to be approximately twice the height H1 of the lower chamber. Advantageously, the height H2 is between 50 and 80 of the casing height.
Percentage and correspondingly the height H1 is 20 to 50 percent of the casing height.

The front wall 42 of the casing is designed as a door 47 in order to ensure a good access to the spinning station 10. According to FIGS. 2 and 3 and FIGS. 6 and 7, the height of the stationary exhaust collector 14 is such that the exhaust opening 2 of the chambers 20, 30 rubbing the stroke range HH.
1,31 is always covered by the collector 14,
Is designed. For this reason, the gap seal 55 constitutes a simple sealing means.

In order to further improve the flow guidance, in the embodiment of FIGS. 4 and 5, a circular opening 45 for the thread balloon 13 is provided.
A baffle or intermediate bottom 40 having a In this case also, in this case, a downward air intake action is obtained for the upper inlet opening 33 in a manner similar to that described above.

Chambers 20, 3 for spindle 11
0 and ring rail, and depending on the winding state of the spindle, an annular free inflow area provided for the air between the edges of the openings 33, 45 and the spindle 11 or the thread balloon 13. And the suction ratio changes accordingly.

By dividing the chamber 30 by the baffle plate 40, the suction effect of the geometry according to the invention is doubled and the effect is magnified over the entire travel height HH. In this case, as a further element for the flow guidance, in the lower chamber 20, a ramp 49 is used which is guided upwards from the bottom 22 and which is the exhaust opening 3.
Immediately before 1, the exhaust gas guided into the second chamber 30 is guided into the exhaust opening 21. In this case, the exhaust gas in both chambers is guided from the exhaust opening 31 to the collector 14 via a hose 53 as a flexible connecting member, for example.

FIGS. 6 and 7 show a two-chamber casing according to the invention with a spindle which is almost completely wound at the upper end of the travel range HH (FIG. 6) and at the lower position at the start of winding ( FIG. 7). In this case, the casing is additionally extended.

A balloon restriction ring 1 is provided in the upper chamber.
Above 5, there is a mounting part 38 with an annular opening corresponding to the cover with the opening 33 of the previous embodiment. Thereby, the upper second chamber 30 is essentially divided by two horizontal baffles 40, 41.

The lower first chamber 20 has an extension 28 which can be pulled out, for example by the action of gravity. Sixth
In the upper position of the figure, the extension portion 28 is pulled out by its own weight,
The extension thus covers the spindle 11 completely. In the lower position of FIG. 7, the extension 28 contacts the stop of the spindle rail 6 and is correspondingly compressed.

All circular openings in the cover, the bottom and the intermediate wall are always designed to provide the required space for the wound spindle and thread balloon in all stroke positions and winding conditions. Further, the plurality of openings in the chamber allow air to flow from the first inlet opening through all the other passage openings to the exhaust openings 21,31, and
Aligned with each other so that they do not cause damming.

In FIG. 7, the exhaust of the chambers 20, 30 is led into a separate collector 14.2, which is the first collector 1 for the air sucked from the draft mechanism 5.
Separated from 4.1. This allows both collectors 1
The wicked fluff of different qualities within 4.1, 14.2 is considered for reuse. In this case, the required suction power is adapted separately for each collector 14.1, 14, 2.

FIGS. 8 and 9 show the divided baffles 40a and 40b in a side view and a plan view. In this case, the front half baffle plate 40 a is provided on the front wall 42 forming the door 47. This makes access to the spinning machine easier.

FIG. 10 shows slanted and divided baffle plates 46a and 46b. When viewed from the front toward the back wall 43, the front half of the baffle plate 46a extends from the upper right to the lower left, whereas the latter half of the baffle plate 46b extends obliquely from the upper left to the lower right.

In this case, when operating the spinning point with Z-twist, it is driven by a yarn balloon or a spindle.
As shown by the arrow, the air rotating around the axis A is pushed forward along the baffle plate 46a from the upper right to the lower left and then at the rear via the baffle plate 46b from the upper left to the lower right. Be done.

As a result, the air spirals downward toward the exhaust opening 31 due to the spiral arrangement of the baffles. For operation in the opposite S-twist direction, the baffles 46a, 46b are switched appropriately, ie the inclination is reversed.

In FIG. 11 an additional vertical deflector 48 is shown near the exhaust opening 31. Therefore, the exhaust opening 3 is adapted to the twisting direction of the spinning point.
An additional exhaust action for air in the one direction occurs. Such vertical baffles are also switched depending on the twisting direction selected and are provided, for example, at the end of the exhaust opening, so that a deflection and damming corresponding to the twisting direction occurs in the collector 14.
