Definitions
- the present invention relates to a device for feeding and dissolving a sliver on an open-end spinning device, with a feed roller, a pressure roller cooperating with the feed roller, an opening roller and two the sliver between the pressure roller and opening roller laterally between leading guide walls.
- the guide walls are arranged on a filling body, which largely seals the space between the nip between the feed device consisting of a feed roller and a pressure roller and the opening roller and also serves to clean the pressure roller (DE-OS 2.130.658) .
- the fiber sliver is supported by the driven feed roller until it is transferred to the opening roller.
- the filler executes radial movements to the opening roller so that the distance between the guide walls and the feed roller changes.
- no reliable guidance of the sliver is achieved, so that fibers also reach the area of the side walls of the opening roller and can lead to a flight there.
- the fibers that collect here are transported from time to time in the form of fiber chunks to the spinning element. About that there is also the risk that the filler is pressed into the region of the clothing of the opening roller when the roll is formed on the pressure roller, so that the opening roller assembly may be damaged.
- the object of the present invention is to provide a device for feeding and dissolving a sliver in such a way that, on the one hand, a uniform and gentle on the sliver is achieved for the opening roller and, on the other hand, safe lateral guidance of the sliver into the region of the opening roller is made possible.
- the pressure roller is mounted in a feed trough which, between the feed roller and the opening roller, has a support surface which supports the sliver and is delimited by the guide walls, and in that the opening roller can be driven in the same direction of rotation as the feed roller. Because the lateral guide walls are arranged on the feed trough, there can be no relative movements between the sliver and the support surface supporting the sliver and the guide walls. This ensures that the sliver fed to the opening roller is always safely guided by the guide walls. The opening roller and the feed roller are driven in the same direction. This also contributes to the fact that it is not the feed roller that supports the sliver on its way to the opening roller, but that this is done by the feed trough.
- the pressure roller ensures that the sliver is conveyed uniformly over its entire cross-section in the direction of the opening roller, since the feed roller does not work together with a counter surface which is stationary with respect to fiber transport, but with a roller which rotates in the direction of fiber transport.
- the pressure roller is mounted in the feed trough, which has a support surface for the fiber sliver after the pressure roller in the fiber transport direction. This creates a gap between the pressure roller and the support surface.
- the support surface of the feed trough is inclined with respect to the tangent which is placed on the pressure roller and the area of the support surface on which the Sliver supplied to the opening roller is deflected in the direction of rotation, the end of the support surface facing the pressure roller being at a greater distance from the feed roller compared to the tangent.
- the fiber sliver fed to the opening roller does not reach the area of the beginning of the support surface and thus also does not reach the area of the gap mentioned, so that the risk that fibers and dirt components get caught here is very low.
- the end of the guide walls facing the pressure roller is at a greater distance from the feed roller compared to the tangent.
- the conveyance of the conveyor belt should be as uniform as possible, seen over the entire cross section of the sliver. It is therefore advantageous if the pressure roller follows the movement of the sliver particularly well. This is achieved particularly well in that the pressure roller has corrugation, whereby corrugation parallel to the axis of the pressure roller has been found to be particularly useful. Alternatively and / or additionally, however, it can also be provided for this purpose that the printing roller has a corresponding coating or a corresponding covering.
- a particularly uniform drive over the entire cross-sectional area of the sliver is achieved if the pressure roller can be driven positively in the opposite direction of rotation at the same peripheral speed as the feed roller. In this way, the staple fiber ribbon receives both from the feed roller as well also the pressure roller an inevitable drive towards the opening roller.
- the support surface has a wiping edge at its end facing the pressure roller.
- the feed trough to have a recess on its side facing away from the feed roller following the pressure roller.
- Such components can accumulate in this recess or can be removed again from this recess.
- the recess advantageously extends to the side of the feed trough facing away from the feed roller. It is advantageous if the recess widens in the direction from the pressure roller to the outer wall of the feed trough.
- this is connected according to an advantageous embodiment of the subject matter of the invention to a compressed air source or a suction air source.
- This compressed air source or this suction air source expediently generates an intermittent air flow with which the possible deposits can be removed in a particularly reliable manner.
- a wiping edge assigned to the printing roller is expediently provided in the recess.
- the scraper edge is expediently formed on the support surface or in the recess as an exchangeable insert, it having proven to be advantageous to manufacture the scraper edge from spring steel sheet.
- the feed trough on its side facing away from the pressure roller has a recess that extends to the outside, it is advantageous if the feed trough is acted upon in the direction of the feed roller outside the recess by a leaf spring.
- the pressure roller it has proven to be advantageous for the pressure roller to be mounted in an oscillating manner in the feed trough, so that the pressure roller can automatically adapt to fluctuations in strip width.
- the subject matter of the invention is simple in structure and can easily be exchanged subsequently in existing devices for previously usual food troughs.
- the invention enables the friction on the clamping surface opposite the feed roller to be reduced, so that the sliver can be fed uniformly over its entire cross section to the opening roller. This is particularly important when the feed device is switched off, since in this way a defined stoppage of the sliver is achieved regardless of the material. This is also of particular importance when the feed device is switched on again, since the fiber stream that arrives at the spinning element starts at a defined time. These defined stopping and start-up conditions ensure that the piecing is more uniform both in terms of strength and in appearance.
- This device has a feed roller 2 which is driven in the usual way and which cooperates with a loading part 3.
- the loading part consists of a feed trough 30, in which a pressure roller 31 is mounted so that it can be brought into contact with the feed roller 2.
- the feed trough with a sliding surface 300 bears against a guide wall 40, which is part of a housing 4 receiving an opening roller 41.
- This guide wall has an opening 400 through which the sliver 1 can be brought into the working area of the opening roller 41.
- the feed trough 30, as seen in the direction of transport of the sliver 1 indicated by an arrow 10, has a guide surface 32 in front of the pressure roller 31 and a support surface 33 behind the pressure roller 31.
- the clamping end 50 of a clamping lever 5 cooperates with the guide surface 32 and is pivotably mounted on a pivot axis 42 carried by the housing 4.
- the clamping end 50 of the clamping lever 5 has a feed hopper 51 for the sliver 1.
- the end 52 facing away from the clamping end 50 works together with the armature 530 of an electromagnet 53, which is also carried by the housing 4.
- the feed trough 30 is pressed against the guide wall 40 of the housing 4 by a compression spring 54.
- this compression spring 54 which is supported on the arm of the clamping lever 5 with the clamping end 50, holds the end 52 of the clamping lever 5 in contact with the armature 530 of the electromagnet 53.
- the feed trough 30 is further acted upon by a U-shaped leaf spring 43, one end of which is supported on the side of the feed trough 30 facing away from the feed roller 2 and the other end of which is supported on the part of the housing 4 which carries the pivot axis 42. In this way, the feed trough 30 is pressed against the feed roller 2 with the pressure roller 31 carried by it.
- a recess 34 is provided in the feed trough 30, which extends as far as the pressure roller 31 and has essentially the same cross-sectional area as that pressure roller at its end facing the pressure roller 31. This recess widens at a greater distance from the pressure roller 31 and extends to the outside of the feed trough 30.
- a hose 60 connects to the recess 34 and is connected to a suction air source 6.
- a fiber feed channel 45 is connected to the interior 44 of the housing 4, which accommodates the opening roller 41, through which the fibers 11 released from the fiber sliver 1 pass through a spinning element (not shown), e.g. is designed as a spinning rotor.
- the feed trough 30, seen in the fiber transport direction marked by the arrow 10 has guide walls 320 and 321 or 330 and 331 on both sides of the guide surface 32 and the support surface 33.
- the sliver 1 to be spun is fed to the feed device consisting of the feed roller 2 and the loading part 3 through the feed hopper 51 in the clamping lever 5 and held together by the side walls of the feed hopper 51.
- the fiber sliver 1 After the fiber sliver 1 exits the feed hopper 51, the fiber sliver 1 is located between the guide walls 320 and 321 of the feed trough 30.
- the fiber sliver 1 then passes between the feed roller 2 and the pressure roller 31.
- the feed roller 2 rotates in the direction of arrow 20 and conveys it the sliver 1 in the direction of the arrow 10.
- the sliver 1 in motion causes the pressure roller 31 to rotate in the direction of the arrow 35, which thus moves in the contact area with the sliver 1 at the same speed as the sliver 1.
- the sliver 1 now passes between the guide walls 330 and 331 onto the support surface 33 and finally into the working area of the opening roller 4l.
- the clothing (not shown) of the opening roller 41 acts on the front end of the sliver 1 and in this case releases fibers 11 from the front end of the sliver 1.
- a tension is exerted on the fiber sliver 1, which holds the fiber sliver 1 stretched between the pressure roller 31 and the region 333 of the support surface 33, on which the fiber sliver 1 is deflected in the direction of rotation of the opening roller 41 indicated by an arrow 46.
- the feed roller 2 and the opening roller 41 rotate in the same direction of rotation, indicated by the arrows 20 and 46.
- a defined supply of the fiber sliver 1 to the opening roller 41 is thus also guaranteed in width.
- the electromagnet 53 is excited. This pivots the clamping lever 5 in such a way that its clamping end 50 bears against the guide surface 32 of the feed trough 30 and the fiber sliver 1 clamps between it and the guide surface 32. During this pivoting movement of the clamping lever 5, the feed trough 30 with the pressure roller 31 carried by it is also removed from the feed roller 2, so that the sliver 1 is no longer subjected to the transport effect of the feed roller 2 which continues to rotate.
- the sliver 1 or its fiber beard takes a defined extended position with respect to the feed trough 30 and the opening roller 41 a. This position is also independent of the material, i.e. of the staple fiber length and the adhesive forces between the fiber material and the loading part 3.
- the fiber feed to the opening roller 41 and thus also to the spinning element, not shown starts again to a defined extent.
- defined piecings are obtained, the tensile strength and uniformity of which can be precisely predetermined.
- the time between the last shutdown of the sliver feed to the opening roller 41 and the new start of the fiber feed must be precisely defined, or the piecing program must be adapted to possibly different downtimes of the fiber feed.
- a defined position of the sliver 1 on the feed trough 30 is brought about by the supply of the sliver 1 to the opening roller 41 with the aid of a feed roller 2 and a pressure roller 31 cooperating therewith, the arrangement of the pressure roller 31 in that with guide walls 320 and 321 Provided feed trough 30 ensures that the width of the sliver 1 fed to the opening roller 41 is precisely defined without the risk of the edge regions of the sliver 1 becoming trapped.
- the feed trough it is entirely possible to pivotally mount the loading part 3, which essentially consists of a feed trough 36 and a pressure roller 31, on a pivot axis 37, which can also serve to support the clamping lever 5 mentioned in connection with FIG. 1 .
- the feed trough 36 is acted upon in a manner known per se by a compression spring 47, which is supported in a suitable manner on part of the housing 4.
- the gap 38 according to FIG. 2 is shown in the direction of transport indicated by arrow 10 of the sliver 1, not shown a scraper edge 39 limited.
- this scraper edge is designed as an insert made from a spring steel sheet, so that the scraper edge 39 can be easily replaced on the one hand and can be adjusted in a simple manner on the other hand.
- a further wiping edge 390 which cooperates with the pressure roller 31 is provided in the recess 340 of the feed trough 30 on the side of the pressure roller 31 facing away from the feed roller 2 and which can also be adjustable and exchangeable. Should fibers, dust constituents, shell particles or other constituents get into the recess 340 and remain adhering to the surface of the pressure roller 31, these constituents are stripped off by the wiping edge 390 and removed by the air flow acting in the recess 34.
- the feed trough 36 is guided in a manner not shown between two sections of a compressed air line 61, with the aid of which a compressed air flow is guided through the recess 340 parallel to the axis of the pressure roller 31 and possibly removes dirt or fiber components that have accumulated there.
- This compressed air flow can act continuously or optionally also intermittently, just as the suction air flow described in connection with FIG. 1 can be applied continuously or intermittently to the recess 34.
- Fig. 2 shows yet another measure by which the risk that fibers or dirt components can get into the gap 38 is reduced. If a tangent 332 is placed on the circumference of the pressure roller 31 facing the feed roller and the region 333 of the support surface 33, at which the fiber sliver 1 fed to the opening roller 41 is deflected in the direction of rotation of the opening roller 41 indicated by an arrow 46, then the support surface 33 2 inclined to this tangent 332. This inclination is chosen so that the end 334 of the support surface 33 facing the pressure roller 31 does not reach the tangent 332 (see distance a), but is arranged at a greater distance from the feed roller 2 compared to this tangent 332.
- a fiber sliver 1 is fed to the opening roller 41 during operation with the aid of the feeding device formed by the feed roller 2 and the loading part 3, the fiber sliver 1 is essentially guided on a path that is connected to the web by the tension caused by the rotation of the opening roller 41 Tangent 332 matches.
- the sliver 1 thus does not come into contact with this support surface 33 in the region of the end 334 of the support surface 33 facing the pressure roller 31, but is kept at a distance from it.
- the sliver 1 Since the sliver 1 can neither expand laterally nor vertically after leaving the clamping line formed by the line of contact between the feed roller 2 and the pressure roller 31, the sliver 1 comes into contact with the support surface 33 before it reaches the area 333, but not so early that the fibers 11 held in the sliver 1 can get into the gap 38. Only fiber constituents and dirt constituents, which - in particular as a result of the compression effect caused by the pressing of the fiber sliver 1 between the feed roller 2 and the pressure roller 31 - had already detached from the fiber sliver 1 and adhere to the pressure roller 31, can pass through the gap 38 in reach the area of the air flow generated in the recess 340 and are thus discharged.
- the pressure roller 31 extends laterally beyond the guide walls 330 and 331.
- these guide walls 330 and 331 that their end facing the pressure roller in comparison to the tangent 332 has a larger distance from the feed roller 2.
- the tension generated in the sliver 1 due to the rotation of the opening roller 41 also prevents fibers 11 protruding from the sliver 1 from coming into contact with the pressure roller 31 in the region of the guide walls 330 and 331.
- the pressure roller 31 is driven by the moving fiber sliver 1. It is therefore advantageous if the pressure roller 31 has a surface such that it is well carried along by the sliver 1.
- the pressure roller 31 can have a suitable coating or covering, e.g. made of rubber or the like.
- a corresponding design of the roughness of the pressure roller 31 has proven to be particularly advantageous, this roughness being formed in the embodiment shown in FIG. 3 by corrugation 310, which in the preferred embodiment shown in FIG. 3 is parallel to the axis of the pressure roller 31 runs.
- FIG. 2 An alternative embodiment of the rotary drive for the pressure roller 31 is indicated in dashed lines in FIG. 2.
- the pressure roller 31 is connected to the feed roller 2 via a suitable gear 21 with the drive of the feed roller 2 in such a way that the feed roller 2 in the direction of arrow 20 and the pressure roller 31 in the direction of arrow 35, i.e. in the opposite direction.
- both the feed roller 2 and the pressure roller 31 give the sliver 1 (see FIG. 1) a movement component in the direction of the arrow 10.
- the device for feeding and dissolving a sliver 1 to an open-end spinning device can be modified in many ways. It is thus possible in particular to replace individual features of the device with equivalent features or to use the features described in other combinations. It is also not always necessary to use all of the features shown at once. 1, it is entirely possible to omit the wiping edge 39 and / or also the wiping edge 390, in particular when the printing roller has a profiled surface, in order in this way to avoid damage to the surface of the printing roller or the wiping edge .
- the recess 34 it is also not absolutely necessary to generate an air flow on the side of the pressure roller 31 facing away from the feed roller 2. It may be sufficient to design the recess 34 in such a way that it contains fiber and dirt components to a removal means, e.g. a conveyor belt provided with a set, or can itself be designed as a collection container that is emptied from time to time, possibly also manually.
- the shape of the recess 34 can also be different than shown.
- FIGS. 1 and 2 show, not only the special shape and storage of the feed trough 30 or 36 plays a decisive role for the described device for feeding and dissolving a sliver, but also the application thereof by one or more springs irrelevant.
- a compression spring 47 as shown in FIG. 2, concentrically with a hose 60 according to FIG. 1, this compression spring 47 surrounding the hose 60.
- the type of drive control for the sliver 1 is also of no importance to the invention.
- the feed roller 2 is assigned a clutch, not shown, by means of which the feed roller 2 can be coupled to or decoupled from a drive.
- Fig. 4 shows a cross section through a pressure roller 31.
- the pressure roller 31 is pivoted with the aid of a pin 311 and a self-aligning bearing 312, so that the pressure roller 31 can adapt to changes in cross-section of the fiber sliver 1 that occur across the width of the fiber sliver 1 .
- the advantages described are obtained.
