Description

comber

The invention relates to a comber with at least one combing unit for combing out the combing unit in a conveying direction supplied fiber material according to the preamble of claim 1.

Such combing machines are z. B. from EP-1449944 A1. The fiber material presented to the combing machine is fed to a nipper unit of a respective combing unit (also called combing head). The, from the closed nipper unit outstanding end (fiber tuft) of the fiber material is combed out via a combing segment of a rotatably mounted below the nipper assembly round comb. About a tear-off device (in the example shown by Abreisswalzen) a fiber package is withdrawn from the combed tuft and soldered with an already formed web. The accessibility for maintenance work in the region of the nipper unit and for the circular comb (or combing cylinder) rotatably mounted below the nipper unit is made more difficult by the lower horizontal nipper plate of the nipper unit shown in EP'944. This circumstance is exacerbated when it is a device which operates on the "Heilmann principle", wherein the lower tong plate of the nipper unit is firmly connected to the machine frame and thus is immovably mounted Published WO

2012/097461 A1 shown. In this embodiment, the feed cylinder, the top comb, and the upper tong plate loading means are mounted on a swing-up frame to improve accessibility to the lower, fixed tong plate. However, the accessibility from the rear side of the comber to the circular comb (eg for cleaning and assembly work) of this known device is not easy. In addition, the visual monitoring of running within the nipper unit material flow is not optimally solved when passing by the operator.

The invention is therefore based on the object of proposing a device on a combing machine which overcomes the disadvantages of the known state of the art. and good accessibility to the nipper unit and mounted below the nipper unit combing cylinder to create.

This object is achieved by proposing that, viewed opposite to the conveying direction of the fiber material, a rear guide surface adjoin the feed surface to the feed trough, wherein the feed surface and the rear guide surface form an obtuse angle β and, seen in the conveying direction of the fiber material - The rear guide surface with respect to a horizontal plane E at an angle α> 35 ° sloping.

In particular, by the corresponding design of the lower tong plate, wherein the supply of the fiber material via a rear feed surface, which in the conveying direction at an angle α of> 35 ° sloping, the accessibility to the nipper unit (in short: pliers) and the visual observation of the material flow significantly improved within the forceps by an operator standing in front of the comber. At the same time, the accessibility to a combing cylinder rotatably mounted below the pliers (round comb) is improved by the proposed oblique orientation of the lower pliers plate from the back of the combing machine. Preferably, the angle α can be between 40 ° and 60 °. In order to improve the accessibility of the forceps also in their area between the feed trough and a front tong lip, it is further proposed that the front guide surface - seen in the conveying direction of the fiber material and with respect to a horizontal plane - at an angle δ> 55 ° sloping , This angle δ may preferably be between 60 ° and 80 °.

For exact fixation and easy attachment of the lower pliers plate of the forceps on the machine frame (in a version according to the Heilmann principle with a fixed lower pliers plate) is proposed that the lower pliers plate has on its underside at least one support surface which is opposite to the rear guide surface and over which the lower tong plate is mounted on a support of the combing unit.

To precisely and easily adjust the distance between the pliers lip of the lower tong plate and the enveloping circle of the combing cylinder mounted under the pliers it is proposed to attach at least one spacer between the bearing surface of the lower tong plate and the carrier. Different (eg color coded) spacer elements with different thickness dimensions can be used. It can also be cumulative with each other several spacer elements with the same thickness.

With these spacers existing tolerances can be compensated or combing resp. the combing quality can be influenced.

Furthermore, it is proposed that the lower tong plate has on its underside, starting from its front end, an arcuate, concave extending portion which faces the front guide surface and the feed trough. In this arcuate portion advantageously protrudes a portion of the attached below the pliers combing cylinder. This makes it possible to form as small as possible the distance between the enveloping circle of the combing segment of the combing cylinder and the nipper lip of the lower nipper plate. This distance can be between 0.3mm and 10mm.

As a result, the tuft protruding from the closed pliers is almost completely gripped by the combing segment of the combing cylinder during the combing process.

Advantageously, it is further proposed that at least one, in the conveying direction of the fiber material extending guide web is provided on the rear guide surface of the lower tong plate within the width of the supplied fiber material, which divides the supplied fiber material into at least two partial streams.

This ensures that the, z. B. supplied from two delivery points fiber material (eg., In the form of slivers) are not mutually negatively affected before it is supplied to the feed cylinder in an entire fiber composite material.

A negative influence could be z. B. thereby arise when two supplied from different sources of supply fiber material strands rub against each other and thus can solve edge fibers from the fiber composite.

For a better transfer of the fiber material from a supply source (eg from a jug) to the rear feed surface of the lower forceps plate of the forceps, suggest that - seen against the conveying direction of the fiber material - the lower pliers plate has an insertion surface, which connects to the rear feed surface and forms an obtuse angle γ with this. This makes it possible to supply the fiber material (eg as a sliver) in an approximately horizontal plane of the forceps, although the lower forceps plate of the forceps is oriented substantially at an angle to the horizontal.

In order to prevent a mutual negative influence on the supplied material flows already in the region of the insertion surface, it is further proposed that the at least one guide web extends into the region of the insertion surface (EF). That Also on the insertion at least one, this surface superior web is provided.

For safe task of the fiber material on the insertion surface is proposed that - seen in the conveying direction (F) of the fiber material - the insertion surface is preceded by a pair of rollers for the supply of the fiber material. Through this pair of rollers, the respective fiber material strand can already be given a rectangular cross-sectional shape, which is desirable for the subsequent combing process.

On the one hand to guide the flow of material on both sides of the lower tong plate until delivery to the feed cylinder and on the other hand to increase the strength of the tong plate, it is further proposed that the lower tong plate - viewed transversely to the conveying direction of the fiber material - one, in the area their lateral edges, the top of the lower forceps plate superior ridge which extend at least partially over the length of the feed surface and the rear guide surface.

The lower tong plate can be made of an aluminum die-cast.

To that, z. B. merging of two delivery points supplied fiber material to a desired width for the subsequent processing process, it is proposed that the, opposing guide surfaces of the webs in their immediately adjacent to the feed trough end regions each over a partial area - seen in the longitudinal direction of the webs - under a Angle so, so that the clear distance between the guide surfaces in the direction of Food trough steadily reduced. By thus, seen in the conveying direction of the fiber material, existing continuous narrowing of the lateral guidance of the webs, the fiber material is gently brought together to a predetermined width. This ensures that the subsequent feed cylinder, a fiber material is supplied with a constant width constant.

So that the fiber mass is also supplied with a constant constant width to the subsequent nip in the region of the front nipper lip of the lower nipper plate, it is further proposed that above the front guide surface two, spaced from each other having guides are mounted. These side guides for the fiber material can additionally be provided with guide sections arranged under a winding, by means of which the width of the fiber mass is again brought together to a predetermined width before it is clamped for the combing process. In this combination, even protruding edge fibers can be incorporated.

Further advantages of the invention will be shown and described in more detail with reference to subsequent embodiments.

1 shows an already known embodiment of a combing machine 1, wherein a longitudinal part LT, which extends between a drive unit A and a belt deposit BA, has a longitudinal beam 8 on which a multiplicity of combing units X1 to X16 arranged side by side are fastened. These combing units generally have a smaller dimension than the combing heads of conventional combing machines. Machines, especially since these are loaded with only two fiber edges Z, which are deducted from below the longitudinal beam 8 parked pitchers F2 to Fx.

The combing units X1 to X16 with a width C are arranged directly next to one another and screwed to the carrier 8, as can be seen from FIG. 8 of the publication of DE-102006026841 A1. The combing units X1 to X16 each have a housing which is provided with corresponding bearing points to support the drive shafts, which are driven by the drive unit A.

The slivers B formed on the individual combing units are laid down on a conveyor table FB (eg a driven conveyor belt) and conveyed side by side in a transport direction D to a following drafting system S. The fiber material warped in the drafting system S is combined into a fiber sliver following the drafting system and then fed to a calender roll pair KW via schematically illustrated transport means. This transfers the sliver to a subsequent funnel TR, via which the sliver is placed in a pot K looped. In this embodiment, a free space FR below the housings of the combing units X1 to X16 with a distance FA to the floor O. This space allows good accessibility to the combing units.

Starting from the embodiment described in Figure 1, an embodiment (Fig.2 - Fig.4) is shown below, which has a simple and inexpensive construction and is easy to assemble.

In the embodiment of Figure 2, a longitudinal part LT of a combing machine 1 is shown, wherein the laterally adjoining this longitudinal part drive unit A is indicated only schematically. Likewise, a subsequent tape tray BA with a drafting unit S is indicated only schematically. These can be designed as in known designs (see FIG. 1).

The longitudinal part LT in Figure 2 and Figure 3 consists of a longitudinal member 7, which is fixed to frame elements RE via schematically shown screws R at its two ends. He has a distance FA to the ground O on. The two frame elements RE are on their undersides each with two height-adjustable feet 20th provided over which they are supported on the ground O. With the adjustable feet, the longitudinal part can be compensated in relation to the ground condition.

Below the longitudinal member 7, a suction channel 17 is mounted, which (see Figure 2 and Figure 3) protrudes into openings 23 of the frame elements RE and there fastened (not shown) is. In the suction channel 17 are arranged at a distance from each other arranged suction nozzle (smaller suction channels) 17 a, which lead to the respective combing unit X1 - X8, in which the combed out during the combing process components (noils, dirt, nits, etc.) sucked from the suction nozzle 17 a and the suction channel 17 are supplied. Via the suction channel 17, which communicates with a source of vacuum, not shown, the aspirated components e.g. fed to a central disposal facility.

The term "combing unit" is to be understood as meaning a device for combing out a pulp with subsequent banding of the combed pulp., Such a device usually consists of the following individual components such as a nipper unit, round comb, fixed comb, pull-off cylinder or one with the round comb cooperating tear-off roller (Heilmann principle) with a subsequent soldering device (eg a screening drum) and a nonwoven assembly with banding.

From Fig.2 it can be seen that on the side rail 7 at a distance G, a plurality of frame shields RS are fixed, which extend vertically upwards. As can be seen from the side view X of Figure 2 in Figure 3 and the enlarged partial view of Figure 4, the longitudinal member 7 has a U-shaped longitudinal profile U with a bottom wall U1. In extension of the bottom wall U1 adjoins the longitudinal profile U, a side wall SW, which extends vertically upwards in the mounted position.

In the resulting space 22 between the one leg of the longitudinal profile U and the side wall W is a lower part of the respective frame plate RS to rest on the side member 7. That is, the frame RS is located with one side on the side wall SW and with its base GF on the longitudinal profile U on. As schematically indicated (FIG. 4), bores 21 are provided in the area of the installation from the respective frame shield RS to the longitudinal support 7, through which screws Ben R through. The threaded portion (not shown) protrudes after mounting in threaded holes (schematically indicated) of the frame plate, whereby the frame plate RS is firmly connected to the side member 7. Thus, the respective frame RS is positioned exactly on the desired position on the longitudinal member.

In addition, and at a distance from the longitudinal member 7, a transverse web QS is provided in each case between two adjacent frame plates RS, which has a length which corresponds to the distance G. The frame plates RS are thus seen in the vertical direction mounted at an exact distance on the side member 7. As indicated schematically in Figures 4 and 5, the transverse webs at their respective ends, with which they rest against the respective frame plate RS, laterally projecting tabs over which they by means of fastening means (eg screws) P on the side plate SE are attached. The side plate can be provided with corresponding stops or depressions, via which the respective transverse web QS is positioned on the frame shield RS.

The individual side shields SE are provided with a plurality of bearing seats 14 for receiving and supporting longitudinal shafts (e.g., the circular comb shaft 15 or the shaft of the brush roller 13). These longitudinal shafts are driven by drive elements, which are located in the drive unit A.

As can be seen in particular from FIG. 5 (enlarged partial view of FIG. 4), in each case a lower tong plate 2 of a nipper unit 10 ("tongs" for short) is fastened to the transverse webs Q. The lower nipper plate 2 has a bottom side Bearing surface AF, with which it rests on an upper surface OF of the transverse web Q. The respective transverse web QS is arranged at an angle k with respect to a horizontal plane E. To adjust the distance a between an upstream nipper lip 5 and 1 and 2, one or more spacer plates 25 can be provided between the surface OF of the transverse web QS and the bearing surface AF of the lower tong plate 2. This can be done during assembly using the enveloping circle HK of a combing segment 29 of a combing cylinder 1 1 rotatably mounted below the forceps 10 The lower pliers plate is exactly aligned in its longitudinal direction (by means of two cylindrical pins (not shown) nd the conveying direction F) positioned on the transverse web QS. The recess V in the support surface AF supports the positioning of the tong plate during assembly. To attach the lower pliers plate 2 on the transverse web QS also screws M are provided, which, as shown schematically, project through through holes DB of the transverse web QS and protrude into threaded holes GB of the lower pliers plate 2. If spacer plates 25 are used, they must likewise be provided with corresponding through holes for the screws M.

Thus, the distance a between the enveloping circle HK of the combing segment 29 of the combing cylinder 1 1 and the nipper lip 5 of the lower nipper plate 2 can be kept as small as possible, the lower nipper plate on its underside following the nipper lip 5 an arcuate, concave extending portion 35 on in which the combing cylinder 1 1 projects with its enveloping circle HK.

On the upper side of the lower tong plate 2, which is opposite to the arcuate portion 35, it has, starting from its front tong lip 5, an obliquely rising front guide surface VF, to which (viewed counter to the conveying direction F) a feed trough 19 connects. The front guide surface VF is inclined in the installed position of the lower tong plate 2 and counter to the conveying direction F with respect to a horizontal plane E at an angle δ> 55 °. Preferably, the angle δ can be between 60 ° and 80 °.

In order to keep the fiber material Z supplied from the feed trough 19 of the front tong lip 5 at a desired width, lateral guides 44, 45 are provided above the front guide surface VF at a distance d (FIG. 6). These guides 44, 45 can - seen in the conveying direction F - be provided with at an angle n extending feed surfaces, which narrow the fiber material in the implementation between the guides again in their width before it reaches the nip at the nipper lip 5. This ensures that the fiber material Z is of constant width for the subsequent combing process.

In the feed trough 19 protrudes within the pliers 10 rotatably mounted feed cylinder 9, which is driven in steps by a drive not shown in detail. The fiber material Z (eg in the form of fiber slivers) fed to the forceps 10 via a pair of rollers 28 arranged upstream of the forceps is guided in a first section on an upper feed surface ZF of the lower forceps plate 2. This feed surface runs approximately horizontally and forms an obtuse angle γ with a (in the conveying direction F). following, located on the upper side of the lower tong plate 2 rear guide surface HF, on which the fiber material Z is further guided in the direction of the subsequent feed trough 19. Viewed in the conveying direction F, the rear guide surface HF is arranged at an angle α> 35 ° with respect to a horizontal plane E sloping. Preferably, this angle α can be between 40 ° and 60 °. Between the feed trough 19 and the rear guide surface HF, the lower tong plate 2 has an insertion surface EF which forms an obtuse angle β with the rear feed surface HF.

The proposed oblique arrangement of the lower tong plate 2, in particular the rear guide surface HF, the material flow within the forceps 10 can be visually monitored by an operator visually. Also, the accessibility to the lower tong plate 2 is improved in order to perform appropriate service. At the same time the access to the below the pliers 10 mounted combing cylinder 1 1 and the brush roller 13 is simplified from the rear side of the combing machine by the proposed skew of the lower pliers plate 2.

FIG. 6 shows a plan view H (according to FIG. 5) on the lower tong plate 2. In the respective edge regions of the lower tong plate 2 webs 40, 41 are provided, which extend over the feed surface ZF, the rear guide surface HF and partially over the insertion surface EF. These webs 40, 41 serve on the one hand for lateral guidance of the moving on the upper side of the lower tong plate fiber material Z, which is present in the example shown in the form of two slivers Z and on the other hand to increase the strength of the lower tong plate 2. This can, for. B. be made of an aluminum die-cast.

To that, z. B. merge supplied from two delivery points fiber material Z to a desired width for the subsequent processing process, the guide surfaces 42, 43 of the webs 40, 41 in their immediately adjacent to the feed trough 19 end regions each with an inwardly inclined by an angle I surface Mistake. This results - seen in the conveying direction F of the fiber material - a narrowing of the lateral guide by the webs 40, 41st That is, the clear distance between the guide surfaces 42, 43 is steadily reduced in the conveying direction F. By this continuous narrowing of the lateral guide surfaces 42, 43 of the webs 40, 41st the fiber material is gently brought together to a predetermined width. This ensures that the subsequent feed cylinder, a fiber material is supplied with a constant width constant. So that collisions (displacements and loosening of fibers in the edge areas) between the two fiber slivers Z supplied at least in the area of application of the fiber material Z to the lower tong plate 2 (ie above the feed surface ZF), a guide web 38 is centrally located above the feed surface ZF attached, which partially protrudes into the subsequent rear guide surface HF. As a result, the merging of the two fiber slivers Z supplied in a width c to form a closed fiber material flow takes place only in a region of the insertion surface EF, shortly before the fiber material is detected by the feed cylinder 9. Threaded holes GB are still schematically shown in FIG. 6, via which the tong plate 2 is fastened by means of screws M on the transverse web QS.

Above the lower tong plate 2, a pivotal frame 4 (or pivot arms) is mounted, which carries an upper tong plate 3, which together with the lower tong plate 2 can form a nip in the region of the front tong lip 5, as from the present view of Figure 5 can be seen. The frame 4 is pivotally mounted about not shown means to an attached to the frame signs RS axis 6 (see double arrow). In the example shown, the over the

Clamping point protruding tuft FS combed by a combing segment 29 of a combing cylinder 1 1. The tuft FS represents the free end of a fiber material, which in the form of one or more slivers Z, which are withdrawn from cans KV, the clamping point of the forceps are fed under the action of the feed cylinder 9. On the opposite side of the combing segment 29, a tear-off segment 30 is mounted, which cooperates in the tearing off of the combed end of the tuft FS with an undeliverable tear-off roller 12. The withdrawn fiber packets are then brought together (soldered) on a subsequent screening drum 16 and formed into a sliver B on a unit 26 (with fleece straightener and calender rolls).

A detailed description of such a device may e.g. B. also be taken from EP-2 350 361 A1. The fiber sliver B formed in this way is deposited on a conveyor table FB (FIG. 4), on which it is transferred to a subsequent drafting unit S with further, adjacent sliver bands of adjacent combing units. The conveyor table FB may consist of a driven conveyor belt.

As already described, the fiber sliver formed on the drafting unit S is fed to a depositing device (belt deposit BA), by means of which it is deposited in cans K in the shape of a loop.

To keep the combing cylinder 1 1 clean, a brush roller 13 is arranged below the combing cylinder and is mounted in bearing units which are integrated in the frame shield of the RS.

To increase the strength of the longitudinal member 7 and thus the entire longitudinal part LT transverse struts 18 are mounted within the U-shaped longitudinal profile. Seen in the longitudinal direction of the longitudinal member 7, the adjoining transverse struts 18 each extend at an opposite angle b to a horizontal plane, which results in a honeycomb-shaped structure of the stiffeners, seen over the length of the U-profile. The individual stiffeners extend - seen transversely to the longitudinal direction of the longitudinal member - about the height of the free legs of the U-profile U.
