Description

  The present invention relates to a frame for a combing machine, comprising a plurality of combing assemblies arranged in a row next to each other, the combing assemblies being mounted between two frame elements The frame elements are supported on a floor and are connected to each other via longitudinal beams extending at a distance to the floor.

  Combing machines used today in practice typically have eight combing heads arranged side by side, each of which is provided with a wrap roll for combing. The fiber fleece combed and fed out by the individual combing heads is collected into a fiber sliver using a known device and supplied to the subsequent draft device unit on the guide table in a direction transverse to the material flow direction of the combing head. Is done. The fiber sliver formed in the drafting device is then lowered into the can in a loop via a focusing wheel (Trichterrad). Such combing machines operate today with nip numbers up to 600 KS / min.

  Such known combing machines have a transmission unit, a longitudinal part with combing heads located side by side, and a drafting device unit with a subsequent sliver storage. The longitudinal part has a machine frame, which consists of a solid floor plate and a solid side shield fixed to the floor plate. The individual assemblies of combing heads are fixed between side shields that also have a support for the longitudinal axis.

  This known configuration is suitable for receiving and absorbing the high dynamic loads that occur during the combing process. However, the assembly work for such a construction of the machine frame is quite costly and requires a competent specialist to be able to make the necessary precise adjustments and adjustments. . Furthermore, the manufacturing cost of the necessary individual members is expensive.

  In order to increase the number of nips and ultimately also to increase productivity, the combing machine disclosed in Swiss Patent No. 681309 (CH-PS 681 309), instead of the known combing head, Individual combing assemblies are used, and these combing assemblies are provided with at least one fiber sliver for combing instead of wrapping a wrap roll. The fiber sliver is supplied to the combing assembly from a can located below the combing assembly. The fiber sliver that has been fed and combed to the individual combing assemblies is gathered at the run-in table and fed to the subsequent drafting device. The run-in table consists of a support extending at a distance from the floor, to which individual combing assemblies are fixed, which support is supported on the floor at both ends. Each combing assembly is driven by an electric motor and must be operated from two sides. Therefore, time-consuming control and operation are necessary.

  Thus, an improved version of the arrangement described above is disclosed in DE 102006026841 A1 (DE-102006026841 A1), in which the proposed combing assembly is located side by side. , Fixed on the support frame supported on the floor on both sides. Between the support portions, the support frame extends at a distance from the floor. The delivery direction of the fiber sliver formed in the individual combing assembly is transverse to the conveying direction of the subsequent conveyor table, as in a general-purpose combing machine. The fixing of the housing of the combing assembly in a support frame (also referred to as a longitudinal beam) shown as a rectangular tubular profile is only shown here schematically via screws.

  Furthermore, in the configuration of the combing machine disclosed in European Patent Application Publication No. 2397583 (EP 2 397 583 A2), a plurality of combing heads are arranged between the right frame portion and the left frame portion. The frame part is supported on the floor. A plurality of additional support portions may be provided on the floor in the central portion. At least two longitudinal beams are provided between the right frame portion and the left frame portion, and the nipper shaft, the circular comb shaft and the detaching roller are held by these longitudinal beams. The fixed form is not shown and described in detail here.

  Starting from the prior art described above, the problem of the present invention is that on the one hand it is sufficiently stable to take up the existing mechanical loads and on the other hand a combing machine, in particular a combing machine. It provides an inexpensive construction of the frame of the combing machine that allows easy and quick attachment of the longitudinal part of the combing machine.

  In order to solve this problem, in the configuration of the present invention, there are provided a plurality of frame shields that are fixed to the longitudinal beam at an interval and are oriented substantially vertically, and the combing assemblies are respectively connected to each other. Supported between two adjacent frame shields, the frame shields being releasably coupled to one another via at least one transverse web extending at a distance to the longitudinal beam. In this case, the expression “lateral” in the concept of “horizontal web” relates to the orientation of the web with respect to the frame shield. Each transverse web is preferably oriented parallel to the longitudinal beam.

  Such a configuration allows the use of frame shields that are as compact as possible, tailored to the size of each combing assembly, and these frame shields can be attached to the longitudinal beam without problems using fixing means. it can. The required stability and dimensional accuracy of these components is obtained through the use of an additional transverse web that is releasably coupled to the adjacent frame shield. That is, the longitudinal beam with the necessary frame shield can be preassembled relatively easily, and the bearing points are then already accurately positioned relative to each other.

  In yet another aspect, a lower nipper plate of the nipper assembly is secured to each transverse web. When configured in this way, the transverse web can be used as a mounting aid for mounting (exact positioning) of the nipper assembly. For the maintenance of the nipper assembly (good accessibility) and for the installation of the feeding device for the textile material, preferably the nipper assembly, in particular the lower nipper plate, is mounted at an angle to the horizontal plane At this time, the lower nipper plate rises rearward from the front nipper lip. Therefore, in the aspect of the present invention, each of the transverse webs is lifted at an angle (α) when viewed laterally with respect to the longitudinal direction of the transverse web and starting from the front operating side of the combing machine. It extends.

  In a further preferred aspect, the longitudinal beam comprises a longitudinal profile, the longitudinal profile comprising side walls projecting on one side beyond the longitudinal profile, and the frame shield comprises: It is in contact with the longitudinal profile and the side wall in the free space between the longitudinal profile and the side wall and is fixed in the area of the contact. Such a configuration increases the torsional strength of the longitudinal beam, particularly in the region of the joint with the frame shield.

  At this time, in a further aspect, the longitudinal profile is formed as an open U-shaped profile on one side, and the opening of the U-shaped profile is on the opposite side of the operating side of the front side of the combing machine. The side wall is open upward and extends upward in the vertical direction as an extension of the bottom wall of the U-shaped profile. This configuration allows for a simple connection between the longitudinal profile and the frame shield, which can be easily installed and installed in the free space that is present for installation. Can do.

  In particular, in a mode in which the strength in the longitudinal direction of the longitudinal profile is further increased, the longitudinal profile of the longitudinal beam includes a lateral stay extending in a direction transverse to the longitudinal direction of the longitudinal profile. If comprised in this way, the bending strength of a longitudinal beam can be raised simultaneously with reducing the weight of a longitudinal beam.

  Preferably, the longitudinal beam can be manufactured as a casting. Similarly, both the frame shield and the frame element can be manufactured as a casting. Each casting is preferably made from gray cast iron or spheroidal graphite cast iron. In this way, all members to be screwed have the same coefficient of thermal expansion, and non-uniform deformation is not caused by heating.

  In order to easily attach at least one suction passage, in another aspect, the frame element comprises a through-opening, in which at least one is arranged longitudinally and parallel to the longitudinal beam. Two suction passages have entered. When configured in this way, the suction passage can be positioned and fixed in this position by simple insertion into the existing through-opening.

  In order to couple the suction passages to the individual combing assemblies, in another aspect, the suction passages comprise suction tube pieces spaced from each other between the frame elements, the suction tube pieces being individually Connected to the combing assembly.

  In order to attach the longitudinal axis accurately and simply, in another aspect, the frame shield includes a bearing housing for supporting the longitudinal axis.

  Preferably, the frame is used in a combing machine.

The calender roller pair KW delivers the fiber sliver to a focusing vehicle (Trichterrad) TR, and passes through the focusing vehicle TR. The fiber sliver is then lowered into a loop in the cans K.

  FIG. 2 shows another already known configuration of the combing machine 1, in which the longitudinal part LT extending between the drive unit A and the sliver storage BA has a longitudinal beam 8. The longitudinal beam 8 has a plurality of combing assemblies X1 to X16 arranged side by side. These combing assemblies typically have smaller dimensions than the combing head of the configuration shown in FIG. 1, and in particular this combing assembly is drawn from the canes F <b> 2 to Fx installed under the longitudinal beam 8. Only one or two fiber slivers Z are supplied.

  Combing assemblies X1 to X16 having a width C are arranged side by side close to each other and, as can be seen from FIG. 8 of DE 102006026841 A1 (DE-102006026841 A1), the longitudinal beam 8 It is screwed to. The combing assemblies X1 to X16 each have a housing, which is provided with corresponding bearing points for supporting the drive shaft driven by the drive unit A.

  As already described in the first known configuration example, the fiber slivers B formed in the individual combing heads are again lowered onto the conveyor table FB (eg driven conveyor belt) and are mutually connected in the conveying direction D. It is supplied to the subsequent draft device S so as to be positioned side by side. The fiber material drawn in the draft device S is collected into one fiber sliver after the draft device S, and then supplied to the calender roller pair KW through a conveying device schematically shown. The calender roller pair KW delivers the fiber sliver to the following focusing wheel (Trichterrad) TR, and the fiber sliver is lowered into the Kens K through the focusing wheel TR. With this configuration, a free space FR is obtained which is located with a spacing FA with respect to the floor O under the housing of the combing assemblies X1 to X16. In this free space FR, for example, cans F2 to Fx which are schematically shown can be installed. This free space FR likewise allows a good access to the combing assembly. Further, it is possible to attach a suction passage for sucking out the components removed from the combing to the free space FR.

  Starting from the last described configuration example, an embodiment of the present invention (FIGS. 3 to 5) having a simple and inexpensive structure and capable of being easily attached will be described below. In the embodiment of the present invention, the desired strength value in the longitudinal portion LT is met and partly further enhanced, so that it can withstand the loads that occur during operation.

  In the embodiment of FIG. 3, the longitudinal part LT of the combing machine 1 is shown, in which the drive unit A connected to the side of this longitudinal part LT is only schematically shown. Similarly, the subsequent sliver storage unit BA with the draft device unit S is also simply indicated. These may be configured as in a known configuration (see FIGS. 1 and 2).

  The longitudinal sections LT in FIGS. 3 and 4 consist of individual longitudinal beams 7 which are fixed at both ends via screws R which are shown schematically in the frame element RE. . The longitudinal beam 7 has a spacing FA with respect to the floor O. Both frame elements RE are each provided with two legs 20 whose heights can be adjusted, and the frame elements RE are supported on the floor O via these legs 20. Via the adjustable foot 20, the longitudinal portion LT can be adjusted in relation to the floor characteristics.

  A suction passage 17 is mounted under the longitudinal beam 7 and this suction passage 17 (see FIGS. 4 and 5) enters the opening 23 of the frame element RE and is fixed there (not shown). ) In the suction passage 17, suction pipe pieces (relatively small suction passages) 17a arranged at intervals are opened, and these suction pipe pieces 17a communicate with the combing assemblies X1 to X8, In each of the combing assemblies X <b> 1 to X <b> 8, components (noils, dirt, nips, etc.) that have been combed and removed during the combing process are sucked out by the suction pipe piece 17 a and supplied to the suction passage 17. The sucked component is supplied to, for example, a central discharge device via a suction passage 17 connected to a negative pressure source (not shown).

  The concept of “combing assembly” should be understood as a device with the function of combing the fiber material and then sliver the combed fiber material. Typically, such devices are, for example, nipper assemblies, circular combs, top combs, detaching cylinders or detaching rollers (Heilman principle) that work with circular combs, with subsequent joining devices (eg screen drums), And individual components such as a fleece assembly guide having a sliver forming function.

  As can be seen from FIG. 3, a plurality of frame shields RS are fixed to the longitudinal beam 7 at intervals G, and the frame shields RS extend upward in the vertical direction. As can be seen from FIG. 4 as viewed from the line-of-sight direction X of FIG. 3 and FIG. 5 which is an enlarged partial view, the longitudinal beam 7 has a U-shaped longitudinal profile U with a bottom wall U1. Yes. On the extended line of the bottom wall U1, a side wall SW is connected to the longitudinal profile U, and the side wall SW extends upward in the vertical direction at the attached position.

  The lower part of each frame shield RS is in contact with the longitudinal beam 7 in the free space 22 formed between one leg of the longitudinal profile U and the side wall SW. That is, the frame shield RS contacts the side wall SW on one side and rests on the longitudinal profile U at the bottom surface GF. As schematically shown (FIG. 5), holes 21 are provided in the contact region of each frame shield RS in the longitudinal beam 7, and screws R pass through these holes 21. After installation, the thread portion (not shown) enters a threaded hole (not shown) in the frame shield RS, whereby the frame shield RS is firmly coupled to the longitudinal beam 7. With this configuration, it is possible to accurately position and fix each frame shield RS at a desired position in the longitudinal beam 7 at the time of attachment. This allows a simple and accurate pre-assembly of these parts.

  In addition to the longitudinal beam 7 and spaced from the longitudinal beam 7, a lateral web QS is provided between each two adjacent frame shields RS. It has a corresponding length. Accordingly, when the individual frame shields RS are attached to the longitudinal beam 7 using the lateral web QS, the frame shields RS can be attached at an accurate distance from each other even in the vertical direction. As schematically shown in FIG. 5, the horizontal web QS has a connecting plate protruding laterally at each end where the horizontal web QS is in contact with each frame shield RS. The transverse web QS is fixed to the side shield SE using fixing means (for example, screws) P via the connection plate. This side shield may be provided with a corresponding stopper or recess, so that the transverse web QS can be accurately positioned for mounting purposes.

  Each of the side shields SE includes a plurality of bearing accommodating portions 14, which can accommodate and support a longitudinal axis (for example, the circular comb shaft 15 or the brush roller 13 axis). These longitudinal axes are driven by drive elements located in the drive unit A.

  In the present embodiment, each lower nipper plate 2 of a nipper assembly (abbreviated as “nipper”) 10 is fixed to the lateral web QS. As can be seen from FIG. 5, a spacer plate 25 may be provided between the upper side surface of the lateral web QS and the lower nipper plate 2, thereby lowering the lower nipper plate 2 with respect to the envelope circle of the circular comb. Can be adjusted.

  A pivotable frame 4 is mounted on the lower nipper plate 2, and this frame 4 holds an upper nipper plate 3, which can be seen from the view shown in FIG. Together with the lower nipper plate 2, a nip location can be formed. The frame 4 is supported so as to be pivotable about a shaft 6 attached to the frame shield RS through means not shown. As an alternative configuration, the frame 4 may be supported by the nipper plate 2 so as to be directly pivotable. In the illustrated example, the fiber tuft that protrudes beyond the nip location is combed by the combing segment of the circular comb 11. The fiber tuft is the free end of the fiber material, and this fiber material is subjected to the action of the supply cylinder 9 at the nip location of the nipper 10 in the conveying direction F as one or more fiber sliver Z drawn from the can KV. Supplied. On the opposite side of the combing segment is attached a detaching segment which cooperates with an accessible detaching roller 12 when the combed end of the fiber tuft is broken. To do. The drawn fiber groups are then combined (joined) in a subsequent screen drum 16 and formed into a single fiber sliver B in a unit 26 (having a fleece concentrator and a calender roller).

  A detailed description of such a device can also be obtained, for example, from EP 2350361 (EP-2 350 361 A1).

  The fiber sliver B formed in this way is lowered onto a conveyor table FB, in which a subsequent drafting device is brought together with another fiber sliver located next to each other in an adjacent combing assembly. Delivered to S. The conveyor table FB may consist of a driven conveyor belt. The fiber sliver can also be transported to a draft device unit in a plurality of, for example, two layers positioned one above the other.

  As already described, the fiber sliver formed in the draft device unit S is supplied to the storage device, and is lowered into the cane K in a loop shape through this storage device.

  In order to keep the circular comb 11 clean, a brush roller 13 is disposed under the circular comb 11, and this brush roller 13 is supported by a bearing unit incorporated in the frame shield RS.

  After the pre-assembly of the frame element RE with the longitudinal beam 7, the frame shield RS and the transverse web QS by the mounting of the bearing unit 14 in the frame shield RS, the required longitudinal axis is utilized by using the elements attached to the shaft. Can be easily passed through from the side. The structure according to the invention of the frame for the longitudinal part LT allows simple and quick installation and precise positioning of the individual assemblies.

  In order to increase the strength of the longitudinal beam 7 and thus to increase the strength of the longitudinal portion LT, a lateral stay 18 is attached inside the U-shaped longitudinal profile U. When viewed in the longitudinal direction of the longitudinal beam 7, the lateral stays 18 adjacent to each other extend at an angle β opposite to the horizontal plane. As a result, a honeycomb structure of the reinforcing material can be obtained over the length of the U-shaped profile. The individual reinforcements extend approximately over the free leg height of the U-shaped profile U as viewed transverse to the longitudinal direction of the longitudinal beam 7.

  As a result, the strength is greatly increased by the attachment of the reinforcing material or the lateral stay 18 and reaches the standard, so that the size and the weight of the longitudinal beam 7 can be kept as small as possible.
