Spinning or twisting machine, in particular two-for-one twisting machine

The innovation concerns a spy or twisting machine, in particular Two-for-one twisting machine of double-sided design, whose workplaces are made by means of external cladding walls Sound-reflecting and / or sound-absorbing material wholly or partially encapsulated from the outside environment are, with at least a part of each work station formed from a single spindle or a spindle group separately assigned cladding wall adjustable for carrying out operating work on this spindle or spindle group is.

With machines of this type, noise is relatively high during operation generates high noise level which is very uncomfortable for the operator working on the machine. Both machine manufacturers and the textile industry have therefore been working on measures to reduce this for years of the noise.

712375620.T273 ^23756201273

Efforts are already being made to especially at the main source of noise, namely the spindle, To install soundproofing devices. So it is for example

to arrange movable plate, which is in the operating position of the spindles in the hash liner frame and old these in their entirety result in a closed protective wall that includes the twisting points (DT-OS 1 510 310). Included The plates can each have a movable spindle carrier assigned or designed as such. These plates or flaps can also each be articulated from several be formed interconnected parts and consist of sound-absorbing material or a support thereof own"

With Falschdrsht-Zviraaasohinen ss is already known (ver = same the magazine "Chemieffaser" May 21, 1971- pages 442 to 446) a cube-shaped, ruman with foam to use a lined sheet metal box in which the Support roller unit 0 is located and only for the drive belt open 1st. IAi on the twisting machine operating work To be able to carry out, this sheet metal box can be pivoted away from the spindle drive belt. With this pivoting of the insulating bleeh box together with the support roller unit However, access to the interior of the machine is free.

According to the last-mentioned prior publication, Basic tests for the shielding of spindle units carried out to study the effect of different materials and cladding. It is essentially Dabai around the following types of cladding:

1. Covering almost completely closed, small slit at the top and bottom for thread passage «}

2. The width of the slot at the top is enlarged for the discharge of the Wara-luftj

3. Slot width on top and bottom enlarged;

■■ ^':' * ^'; V "';7'" · .,. ■■■■■■■ - ■ '

4. top completely removed;

5. Bottom completely removed;

6. Top and bottom completely removed - only front wall available.

However, with all known arrangements it is necessary » to open the machine room, which is completely or partially encapsulated from the outside, in order to carry out operating work, so that the operator is then essentially exposed to the noise which prevails under the adjusted or opened cladding wall or protective wall. The soundproofing conventional type is therefore only fully beneficial to those operators who carry out other work, such as changing bobbins etc.

The innovation is based on the task of making a spinning or twisting machine, in particular a Vim An »V

guarantee for the person directly operating the spindle, if operating work is to be carried out on the individual spindle or on a spindle group or on an entire machine side are. At the same time, however, the fact must be taken into account that in the production of threads & of Two-for-one twisting machines Flying fibers and soiling can occur, so that inside the machine for suction the fiber flight od. The like. Flow cross-sections should be as free as possible, so that an otherwise Offering · All-round encapsulation of every workstation or spindle is prohibited.

To solve this problem, the innovation according to the machine is characterized in that the lining wall is adjustable in such a way that the adjusted lining wall of the Rest of the machine interior with the exception of the spindle or spindle group to be operated towards the outside environment is completely or partially encapsulated.

712375620.1273

The main idea behind the innovation is thus essentially that of the normal operation of the machine Workplaces or spindles to the outside delimiting cladding walls or cladding wall parts to carry out service work so adjustable that after the adjustment, i.e. opening the cladding wall towards the outside, a demarcation of the work area to be served or Spindle or spindle group against the interior of the machine this adjusted cladding walls or wall parts is obtained, so that the first delimiting the spindle to the outside Cladding wall part comes to lie behind the spindle and thereby the remaining interior of the machine against the The spindle area open to the outside is delimited and encapsulated, with a central suction system for the other spindles is not interrupted.

The main sound-absorbing materials used it is usually fluffy fabrics with a large surface and large-pore character, so that the possibility is given to absorb the sound over a large frequency range au. Dust adheres extremely well to such materials slightly, although in cases where the finishing agent is used in the area of the twisting point, there is also a loss of time and as a result, it is to be feared that the sound-absorbing materials will become unusable. Sound absorbing materials are still sensitive to mechanical stresses, so that it is as far away as possible from the place of work, i.e. in the present Fall from the spindle work area should be arranged.

For this reason it is provided according to a further innovation in double-sided machines that between the two rows of spindles a sound-absorbing wall extending over the entire length of the machine is arranged, the old distance to the adjustable cladding walls assigned to the individual spindles or spindle groups and ικη their upper edge soundproofing preferably extending to both sides

712375620.1273

Connect sorbent walls that come close to the spindle axis each spindle row can reach. With "" aer such Design can encapsulate the spindles or spindle groups, i.e. the workplaces, from the outside Cladding walls to a large extent be made of la substantially smooth material that has a relatively low absorption value and directs the sound against the sound-absorbing walls, where it is converted into heat.

According to a further innovation it is provided that a single spindle outwardly shielding adjustable · cladding wall the shape of the spindle over part of the circumference and optionally has a part of its height surrounding the hollow cylinder which is rotatably mounted about the spindle axis. This rotatable «storage is preferably carried out in the area of the Spindle whorl. If in such a configuration the If the spindle is to be made accessible to an operator, the hollow cylindrical casing wall only needs be rotated around their axis.

IAn to achieve further sound insulation is according to further Innovation provided that on the hollow cylinder jacket on the bottom and / or top a radially inward protruding flange section made of sound-reflecting and / or sound-absorbing material.

Since in a two-for-one twisting machine, as a rule, for operating purposes there is not one that extends over the entire spindle height Area needs to be accessible to the operator, there is advantageously also the possibility of only to make the parts of the cladding wall adjustable in the manner described, which are in the area for the necessary free access for an operator to the workplaces.

According to further hiring it is provided that each spindle

7123756201173

or spindle group associated adjustable cladding wall has the shape of a blind, which consists of one of the respective Spindle or spindle group to the outside shielding position along a curved path to a position behind this spindle or spindle group is displaceable, preferably spindles between the individual or the individual combined Spindle groups are arranged stationary side cladding walls.

The principle according to the innovation, namely that of normal operation of the machine for sound insulation and / or soundproofing, cladding walls or cladding wall parts acting towards the outside la case to adjust the access necessary for operating work on the spindles and to use the remaining Machine interior opposite the spindle to be operated br *. Encapsulating the spindle group can be done according to further Innovation can also be realized in that the adjustable cladding wall assigned to each spindle or spindle group visor-like from a position that shields the respective spindle or spindle group from the outside into a Position behind this spindle or spindle group can be folded down, preferably between the individual spindles or stationary lateral cladding walls are arranged on the individual combined spindle groups.

The goal, then, to isolate the machine from sound is guaranteed when the outer adjustable cladding walls or wall parts for the purpose of access to a Spindle or spindle group are adjusted or pushed away, can, according to another innovation, also be achieved by that the adjustable outer cladding walls are mechanically connected to inner cladding walls that are adjusted when i.e. opening the outer cladding wall parts from one of the rest of the machine interior towards the one to be operated Spindle or spindle group in a non-isolating position in the rest of the machine interior, with the exception the spindle or spindle group to be operated to the outer one

712375620. XL 73

Surroundings are still fully or partially encapsulating position can be moved. Such a configuration, namely Assignment of separate inner cladding walls or wall parts has the advantage that it also already Have existing, working machines provided with optimal sound insulation, since such a dichotomy of outer and inner cladding wall parts a very large freedom with regard to the arrangement of these wall parts given is.

According to a further innovation, Babel can have that or the external adjustable cladding wall parts along guide tracks and od via a cable. Like. With the or the inner cladding wall parts are in communication, so that upon actuation of the outer cladding wall parts to open the spindle area or the workplaces of the spindle area at the same time the inner cladding walls be moved into their shielding position towards the interior of the machine.

Even with such a division of the outer and inner cladding wall parts, there is a further innovation Possibility of making the outer adjustable cladding wall parts visor-like in such a way that they consist of one of the operating areas the respective spindle or spindle group to the outside shielding position in an open position are pivotable, the inner lining wall parts lying behind the spindle or spindle group being rigid with this or connected to these outer cladding wall parts and thereby either in their AbscfalrmstelluÄg together with them or can be pivoted into their open position. The innovation is shown in the following on the basis of the accompanying drawings in preferred embodiments are illustrated in an exemplary manner, described in more detail. Show it:
