Description

Detailed Description of the Invention

BACKGROUND OF THE INVENTION The present invention relates to a fiber comprising a number of spinning positions in which the installation position is engaged with respect to the can containing the fiber bundle to be spun, and a conveyor belt having essentially horizontal sections and essentially vertical sections. The present invention relates to a spinning machine equipped with a transport device for transporting a bundle from a can to the spinning position.

In a known spinning machine of the type mentioned at the beginning (GB patent 10 15 780), the installation locations are arranged in rows in front of the spinning machine. The fiber bundles are drawn by rolls installed above the cans, then pass between pairs of conveyor belts starting between the rows of installation locations, and then proceed vertically downwards there, and further below the floor in a ring spinning machine. To the center and run upward from there towards the stretching device.

Unpublished German patent applications (P 41 09 026.8 and P 41)
No. 09 096.9), it is proposed to equip a conveyor belt for conveying the fiber bundle between the can and the installation site, and at that time, a sliding plate that presses the fiber bundle against the conveyor belt with a light pressure. Are partially arranged.

The object of the invention is to simplify a spinning machine of the type mentioned at the outset.

For this purpose, the conveyor belt is covered in at least essentially horizontal sections by slide plates, which are supported on the conveyor belt and at their ends in essentially vertical sections. This is achieved by having a transitional turning guide.

The slide plate presses the fiber bundles onto the conveyor belt with a light pressure, so that a reliable and draft-free conveyance is achieved without the need to install a large number of driven and / or rotating elements. At this time, the fiber bundle is flattened and guided correctly, so that the parallel state of the fibers is maintained.
The sliding plates also function by their turning guides so that the fiber bundles remain on the conveyor belt in the transition range from the horizontal section to the vertical section. This type of feeding of the fiber bundles from the can to the spinning position does not cause drafts in the fiber bundles during transport of the relatively thin fiber bundles, i.e. fiber bundles with a fineness of 0.3-0.8.
It is possible to reliably convey and supply.

In a further development of the invention, it is provided that the slides, which are arranged in essentially horizontal sections of the conveyor belt, are guided laterally in the conveyor belt. As a result, it is possible to provide a sliding plate having a simple structure that is adjusted on the conveyor belt.

In a further development of the invention, it is provided that the sliding plate arranged in an essentially horizontal section of the conveyor belt is positioned by a stop member in the direction of travel of the conveyor belt. Thereby it is provided in particular that the deflection guides of the sliding plate are arranged at a constant position with respect to the conveyor belt without great expense.

In a first embodiment of the invention, the ends of the sliding plates arranged in the essentially horizontal section of the conveyor belt are curved and their radius of curvature is such that the associated conveyor belt is deflected in this range. It is provided that it is adapted to the diameter of the turning rolls.

In another embodiment of the invention, it is provided that the end of the sliding plate, which is arranged in the essentially horizontal section of the conveyor belt, is provided with turning guide elements. These turning guide elements can have a special shape, for example a compressor shape.

In another aspect of the invention, it is provided that the sliding plate is provided with guide grooves for the longitudinally extending fiber bundles. This ensures that lateral deviations of the fiber bundle from the conveying direction are prevented.

In yet another aspect of the invention, an insertion element is provided for inserting the fiber bundle between the conveyor belt and the associated slide. This ensures that the fiber bundle is inserted at a fixed position between the conveyor belt and the associated slide plate and is properly conveyed.

Other features and advantages of the invention will be apparent from the following description of the embodiments shown in the drawings and from the dependent claims.

The spinning frame (1), which is preferentially a ring spinning frame only as outlined in FIG. 1, preferably has a number of spinning positions (2) on both machine sides. Only one of these spinning positions, the drawing device (3), is shown, but it is designed as a three-cylinder drawing device. A fiber bundle (4) drawn from each can (5) is supplied to each drawing device (3). The can (5) is mounted on the pedestal (6) at a high position above the spinning machine (1). In a manner not shown in detail, the cans (5) are installed in several rows extending in the machine longitudinal direction, because the diameter of the cans (5) is the spindle of the spinning machine (1).
This is because it is bigger than the pitch.

A relatively thin fiber bundle (4), that is, a fiber bundle finer than the conventional one is processed. These fiber bundles (4) have a fineness of 0.3 to 0.8, preferably 0.5 to 0.7. Due to this fineness, the fiber bundle (4) can be drawn into a fiber bundle (7) or roving having a high fineness in the three-cylinder type drawing device (3), and the feeding roller pair of the drawing device (3) can be drawn. The speed of rotation is high enough to guarantee full rotation.

In order to ensure that the fine fiber bundles (4) do not undergo undesired drafts during their transport to the spinning position, the fiber bundles (4) are first drawn upwards in the direction of the arrow (A), A transport device (8) is then provided, which feeds approximately horizontally in the direction of the arrow (B) to approximately the center of the machine and from there to feeds the lower stretching device (3) in the direction of the arrow (C). The drawn fiber bundle (7) proceeds from the drawing device (3) in the direction of the arrow (D) and further reaches a twisting device (not shown). This twisting device is preferentially a ring spindle. However, it is also possible to install a lap spindle, an air nozzle or the like as the twisting device.

The transfer device (8) has a horizontal transfer section (1
0) and a number of conveyor belts (9) forming a conveyor section (11) perpendicular to the belt. The conveyor belt (9) is shown in FIG.
As illustrated in FIGS. 3 and 7, they are each formed wide enough to accommodate two juxtaposed fiber bundles (4). These fiber bundles (4) are fed to two adjacent drawing devices (3), i.e. in a known manner, a drawing device (3) with a common holding roller pair as the upper rollers. The cans (5) from which both fiber bundles (4) are drawn are juxtaposed and they are arranged in one common row or in two adjacent rows. The conveyor belt (9) starts approximately in the middle of the area between the cans (5).

The conveyor belts (9) are guided by turning rolls (13, 15, 16) such that they exhibit a square run consisting of a horizontal section (10) and a vertical section (11). The fourth turning roll (14) is the turning roll (1
3) Since it is arranged at a slightly lower position on the lower side, the returning inter-vehicle portion of the conveyor belt (9) also follows this rectangular traveling. The turning roll (15), which is arranged close to and above the can (5), is held by the tightening member (18),
This member is pivotable about an axis (19) extending in the machine longitudinal direction and is fixed in position on the carrying device (21).
The conveyor belt (9) is loaded so as to be tensioned by the leaf spring (20) supported by. Tightening member (1
8) comprises entry funnels (17) for the fiber bundle (4), ie preferably two insertion funnels (17) each. It should be pointed out for the sake of clarity that in a practical machine the adjacent conveyor belts (9) have horizontal sections (10) with different lengths, respectively, but they do not correspond to the respective can rows in question. ) Is arranged to start in the middle of the two cans.

A sliding plate (22) is engaged with each of the conveyor belts (9), and since the sliding plate is mounted on the fiber bundle (4) by its own weight, the fiber bundle (4) is lightly pressed. It is pressed against the conveyor belt (9). The sliding plate (22), which is preferentially made of iron plate, has a smooth lower surface with a coefficient of friction that is much lower than that of the conveyor belt with respect to the fiber bundle (4). In some cases, the sliding surface of the sliding plate (22) is coated with a coating material. However, the surface quality of unrusted steel is usually sufficient.

Since the front end (23) of the sliding plate (22) protrudes from the turning roll (15), a groove-like entry portion for the fiber bundle (4) is formed. Sliding plate (22)
The rear end (24) in the transport direction of the is provided with a turning guide portion (12) for turning the fiber bundle (4) downward in the range of the turning roll (13) toward the vertical section (11) of the conveyor belt (9). Form. In the embodiment based on FIG. 1,
The turning guide (12) is formed by the curved end (25) of the sliding plate (22), the curvature of which conforms to the outer circumference of the turning roll (13). In this way, the rear end (24) of the sliding plate (22) surrounds a part of the outer circumference of the turning roll (13).

The sliding plate (22) is a guide element (26, 27).
With which the sliding plate (22) is guided on the side of the conveyor belt (9).

As shown in FIG. 2, the guide element (26,
27) is formed as a U-shaped holding element attached to the sliding plate (22) as a kind of platform. Side rail (3
The leg portion (34) protruding from 3) has a recess (35) at a position apart from the cross rail (33), and the sliding plate (22) is sandwiched between the leg portions (34) at that portion. The guide elements (26, 27) are made of elastic plastic. As can be seen from FIG. 2, the legs (34) have a spacing slightly larger than the width of the conveyor belt (9). Figure 2
The guide element (26) engaging the front end (23) of the sliding plate (22), as indicated by the line (36) at the end, is more than the guide element (27) engaging in the range of the rear end (24). Has short legs. The longer legs (34) of the guide element (27), represented by (28) in FIG. 1, provide a stop member by which the sliding plates (22) are positioned in their longitudinal direction on the conveyor belt (9). Form. By the traveling conveyor belt (9), the slide plate (22) is conveyed in the conveying direction (arrow B) until the stop member (28) contacts the turning roll (13). As a result, the turning guide portion (12), that is, the curved end portion (25) can be accurately positioned on the outer circumference of the turning roll (13). In this case, the guide element (27) is attached to the slide plate, e.g. by means of a fixed groove, so that it can be adjusted in the longitudinal direction of the slide plate (22), so that the deflection guide (12) can be adapted to different fiber bundle thicknesses. It is rational to

Since the sliding plates (22) are not fixedly mounted on the conveyor belt (9) or the fiber bundle (4), they are easily taken out by the operator, which is the spinning machine (1). It is advantageous to insert the fiber bundle (4) during operation or change of setup.

A slide plate (29) is also arranged in the vertical section (11) of the conveyor belt (9). These sliding plates (2
9) consists of a thin spring steel plate suspended on an upper retaining device (30) in the center of the machine. The slides are guided by rods (32, 32 ', 32'') which penetrate in the machine longitudinal direction such that they bear against the vertical section (11) of the conveyor belt (9) with a slight pressure. In some cases it is possible to dispense with these vertical slides (29). This is especially true when the sliding plate (22) presses the fiber bundles (4) onto the conveyor belt (9) such that they are held by light adhesion on the surface of the conveyor belt (9). This is further aided by the fact that the conveyor belt (9) is roughly formed on the upper surface on which it is conveyed or is provided with moldings, eg holes. It should be mentioned that the turning rolls (13, 15, 16) and the turning rolls (14) also comprise annular collars, so that the conveyor belt (9) is guided on its side.

As shown in FIG. 3, the modified embodiment has a U-shaped cross section and also has their legs (38).
The sliding plate (3) that holds the side surface of the conveyor belt (9) by the
7) is provided. In this case, the auxiliary guide elements (26, 27) can be omitted. However, it must be ensured that the sliding plates (37) are guided positively with respect to their turning guidance in the transport direction.

In the embodiment according to FIG. 4, the sliding plate (2
It is provided that the guide element (27) of 2) is supported by a preferably adjustable stop member (41) arranged above the sliding plate (22) rather than the turning roll (13).

In the embodiment according to FIG. 5, the horizontal section (1
It is provided that the sliding plate (42) which engages 0) comprises a turning guide (43), preferably made of plastic, as a separate member. This turning guide element (43)
Is a forming member having a curved inner surface on the side of a turning roll (13) for turning the fiber bundle (4) in the direction of the vertical section (11). Here, the bend (44) can be provided with lateral divider bars, so that it acts as a kind of compressor for the fiber bundle (4). The turning guide element (43) comprises a leg (45) surrounding the associated conveyor belt (9), which rests on the turning roll (13), whereby the sliding plate (42) and the turning guide element (43). 43) is positioned. The turning guide element (43) is rigidly connected to the slide plate (42), for example by means of a clasp connection or an adhesive. In an embodiment different from the embodiment according to FIG. 5, the turning guide elements (43) comprise replaceable inserts, which act in the area of the bend (44) and, by their replacement, different weights. It is provided that an exchange for the weaving bundle of sasa is possible. Such inserts can also be designed as compressors, that is to say they can have side rails that narrow in the conveying direction.

In the embodiment according to FIG. 6, the slide plate (46) shown therein is provided with a guide element (47) in the form of a cradle, which element by its legs (48) conveys a conveyor belt ( It is provided to enclose 9) in the area of the front turning rolls (15). The guide element (47) is engaged by an adjustable stop member (49) against which the guide element rests in the conveying direction (B) of the conveyor belt (9) and thus the sliding plate. (46) is positioned by a turning guide portion (not shown).

FIG. 7 shows a sliding plate (50) with two longitudinal grooves (51) extending away from each other, which groove serves as a side guide for the fiber bundle (4). Each slide plate (22, 37, 42, 46) of the previously described embodiments can also be provided with such a vertical groove (51).
