Abstract

PURPOSE: To improve the convergence action of a sliver end and a controlled following-up action of an auxiliary sliver by forming a common pressurizing clearance in separated conveyance passages for the sliver and a preliminary sliver, and parallel-feeding the stating end parts of the sliver and the preliminary sliver into the pressurizing clearance. CONSTITUTION: A common pressurizing clearance 47 is formed in separated conveyance passages 118, 18a for a sliver 12 and a preliminary sliver 12a, and the starting end parts of the sliver 12 and the preliminary sliver 12a are parallel- fed into the pressurizing clearance 47. The preliminary sliver 12a acceleratedly- fed through an introduction table is compressed together with the running sliver 12 by the pressure of a pressurizing roller 48 against the conveyer belt 18a, and an angle of an introduction direction to a delivery direction can be selected freely. Especially, by using a change direction carrier acting tangentially, it is possible to deliver the sliver 12 in any direction, or change the sliver which has almost finished its work with the preliminary sliver 12a.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The invention relates to a device for feeding sliver drawn from a can or similar storage container to a textile processing machine via conveying means of an introduction table. In this case, a standby spare sliver is associated with the sliver conveyance path, and the spare sliver is connected to the sliver transport path in such a way that, when the sliver is destroyed or terminated, the starting end of the spare sliver is spliced to the end of the running sliver. This invention relates to a device capable of operating a sliver based on a control unit. [Prior Art] Individual slivers are drawn out of a spinning can via a pair of rollers arranged above the spinning can and transferred to a subsequent sliver via a plurality of support rollers or other guiding means.
! The equipment for feeding processing machines (for example drawing machines) is known from practical use. According to German Patent Application No. 22 30 644, the sliver to be processed is removed from the spinning can via a take-off roller and fed to a conveyor belt for further transport. Associated with each so-called working can is one so-called spare can arranged in pairs, the sliver of which is taken up as a spare sliver via a pair of draw-off rollers and placed in a waiting state. Retained. The sliver and spare sliver drawing roller pair is
They are arranged linearly from front to back when viewed in the transport direction. In the event of a sliver failure, the attached spare sliver drawing device is activated via the control device. This ensures automatic follow-up of the spare sliver when the sliver breaks or ends. It is considered a disadvantage of this type of transverse construction that the connection of the sliver ends remains incomplete, especially if the latter slivers do not move exactly in a straight line. This significantly limits the placement possibilities of the introduction table. [Problem to be Solved by the Invention] To this end, the inventor of the present invention avoided the above-mentioned drawbacks of the known devices and solved the convergence effect of the sliver end at any angle between the input direction and the output direction, as well as the preliminary The task was set to improve the controlled tracking action of the sliver. On top of that,
A reliable introduction table is produced in a particularly simple manner,
It is also required to be maintainable. [Means for Solving the Problem] The problem is that a common pressurizing gap is associated with the separately configured conveyance paths of the sliver and the preliminary sliver, in which case the sliver and the preliminary sliver The problem is solved by a device that can supply the starting end of the preliminary sliver to the pressurized gap in parallel. Furthermore, the pressure gap should be configured as a roller gap defined by a roller, which roller is arranged on a roller axis extending approximately perpendicular to the conveying path of the sliver. Such a measure guarantees an optimal convergence effect at the sliver ends. According to other features of the invention, one of said rollers is
Reversing means of a rotating belt conveyor, which belt conveyor overlaps the conveying path of the sliver and the attached spare sliver at an approximately horizontal adjustment angle. In this case one of the rollers of the belt conveyor is
It can be used as a pressure roller to come into contact with the part between the cars facing each other in the conveyance direction. Advantageously, a plurality of roller pairs are arranged side by side,
The roller gaps of the roller pair are provided at intervals from each other along the conveying direction. Further, the respective axes of the pressure rollers may be positioned at 151 intervals from each other along the delivery direction. It is particularly important that the side guide portion, which constitutes a funnel-shaped surface that captures both of the conveyance paths, is arranged in front of the roller gap. The invention makes it possible to change the direction of the free end of the sliver at any angle and to replenish the same sliver end during the same change in direction. That is, the preliminary sliver fed through the introduction table at an accelerated rate is
Due to the pressing force of the pressure roller against the transfer belt, the sliver is compressed together with the sliver running away. In this case, the angle between the introduction direction and the delivery direction can be freely selected.
In particular, by using tangentially acting reversing conveyors, it is possible to feed the sliver in all directions or also to exchange half-finished sliver with spare sliver. Within the scope of the solution to the set problem, it is provided that each transport means or each transport path of the introduction table can be driven individually or in groups in relation to each sliver and each preliminary sliver. It is constituted by a separate guide element, in particular a transfer belt, which
connected in series at an angle to at least one delivery-side transfer element; In order to easily follow the preliminary sliver, the respective transfer bells for the sliver and the preliminary sliver)
・must be arranged parallel to each other in pairs. It has also proven advantageous to connect pairwise integrated transfer belts to one another in a controlled manner. By using individual transfer belts, it is possible to set the length of the transfer belt so as not to exceed the required quantity. This means that each transfer belt can start above the associated spinning can and end at a common transfer position. Each starting end of the sliver arranged in stages is provided above each spinning can that is aligned. The mass of the transfer belt to be moved is limited to the minimum necessary, resulting in a relatively low drive output and relatively little dust kick-up. The proposal to configure the deflection roller on the inlet side of the transfer belt, in cooperation with a pivotable pressure roller, as a withdrawal means for the sliver allows for a compact arrangement. In this case, the sliver is guided directly onto a transport belt for further transport, without significant changes in direction. The idea of the invention of mounting the separate transport belts on respective base parts or supports is of particular importance and is placed under independent protection. The base of the introduction table should be composed of modules according to the requirements of the time. For this purpose, the individual supports have a drive roller at one end and a deflection roller at the other end, preferably the latter deflection roller (but not the drive roller). It has turned out to be advantageous for the belt to be movable in the axial direction on the support as a tension roller for the transport belt. The support body is constituted by a tubular cross-section member, on which a U-shaped cross-section member is placed. In the cross-sectional space of the U-shaped cross-section member, an upper inter-car portion of the transfer belt is located and can be moved protected therein. For the other inter-car part of the transfer belt, a tubular or diagonal additional element is provided below the tubular cross-section element, in which at least one sag-preventing element is provided. A support roller is attached. The support roller may also be located in a cross beam holding the support apart from the clean additional member. A plurality of parallel supports are held by at least one common crossbeam as part of the base of the introduction table, so that the base requires only a small number of parts. It is particularly important that the support can be constituted by axial support elements, on which each support element the transport belt is commonly stretched. The support member is produced in a prefabricated manner with predetermined pattern dimensions of various lengths. In this case, there should preferably be a basic length and also dimensions 1.5 and 2 times that length. According to another embodiment of the invention, the drive of the transfer belt is provided in a drive unit attached as a module to the support, the drive unit being arranged in a loop of the endless transfer belt. Contains engaging drive rollers. In order to improve the sliver insertion, at least one pressure roller can be pivoted around the drive roller, the pressure roller itself being part of the drive unit. or external to the drive unit and pivoted to a support of the drive unit, or pivoted to an adjacent support that overlaps said support opposite in the conveying direction. Embodiments Other advantages, features and details of the invention will become apparent from the following description of preferred embodiments and from the drawings. An introduction table 10 of the textile machine for processing the sliver 12 is arranged above a so-called can 14 from which the sliver 12 is guided by rollers 16 onto an introduction table lo. Spare cans 14a are arranged alternately with the cans 14, and a spare sliver 12a is guided to the introduction table 10 from the spare cans 14a. The end 12e of the preliminary sliver 12a at the front along the supply direction
In order to avoid interruptions in the sliver supply, it is joined to the rear end 12i of the sliver 12 which runs away adjacently. The individual slivers 12 or auxiliary slivers 12a reach separate transport belts l8 or 18a. As can be seen, for example, from FIG. 1, the transfer belts of stepwise length are connected with their delivery ends to a transfer head 20. In FIG. 3, 19 indicates a lateral guide. The guide section is a transfer belt 18.
Sliver 12.1 over the entire length of 18a or a part thereof
Located on the side of 2a. Also present in the area of the transfer head 20 is a drive roller 23 for the transport belt 18.18a, which is connected to a drive 22. Although not shown, the transport belts 18 to 18a can be driven individually or in groups via drive rollers 23.
The drive roller 23 is associated with a clutch and a brake (not shown), and is connected to a control unit 24. In front of the drive roller 23 in the conveying direction It is attached to. Drive roller 23 and redirected feed belt 18.1
The transfer belt 20 constituted by 8a is taken over below by a relatively short conveyor belt 32 common to each conveyor belt 18.18a. The width of the conveyor belt corresponds to at least the width of the pulling head 20. Two mutually inclined side guide portions 34 are provided above the upper inter-vehicle portion 32h of the conveyor belt 32. The side guide section grabs the sliver 12 located on the outside and turns the sliver to the conveying roller 38 which forms a roller gap 37 together with the reversing roller 33 at the rear of the conveying belt 32. Inside the funnel-shaped surface defined by each side guide 34, an intermediate guide 36 is provided which is inclined with respect to the longitudinal axis A of the transporter. Associated with each guide N34, 36 is a sliver 12 together with an adjacent spare sliver 12a. The sliver 12 in FIG. 3.4 is guided by guide elements 34, 36 into the roller nip 37 and is cut into a single fiber in the same roller nip in the area of the drawing machine 40. 1142
It is converged to In the embodiment of FIG. 4, two introducing tables 10 for two slivers 12 and two pre-slivers 12a respectively are arranged with adjustment angles w 1 , w 1 relative to the longitudinal axis A of the conveyor. It also abuts the central guide 35 in the region of the transfer head 20. While it is possible to adjust any introduction angle t of 90° or less between the transport direction X on the introduction side and the delivery direction y,
In order to guarantee the reliability of the operation when converging the sliver 12 and its spare sliver 12a at an introduction speed of 001/Win, as shown in FIG. Two vertically oriented belt rollers 44.44a are arranged on the straight line G. In the illustrated example, when the introduction angle t is 90', the straight line G is at an angle of 130° to 140° with respect to the longitudinal axis A of the conveyor.
It forms an adjustment angle t1 of °. For example, 2 belts are arranged around both belt rollers 44, 44a.
The direction changing belt conveyor 46 rotates at 600 RPM.
The sliver 12 is brought into contact with the transfer belt 18 at the adjustment angle t1 into the roller gap 47. The roller gap is limited by the direction change belt conveyor a'l 46 and the lateral pressure rollers 48. The roller gap 47

6, the preliminary sliver 12a passes through the roller gap 47.
The free end 12c of the sliver 12c is pressed by the pressing force of the pressure roller 48 against the sliver 12 being sent out. The strength of the joint 1 2 i / 1 2 e is sufficient to allow the delivered sliver 12z to be introduced into a drawing machine or the like. In this case, a transfer belt 18 for the sliver 12 or a transfer belt 18a for the preliminary sliver 12a
It is not important which of the two is closer to the pressure roller 48. Corresponding to FIG. 6, the distance e in the delivery direction y of each belt roller 44 of the direction changing means associated with each other is also

Consisting of 48. In this case, due to the short clamping stroke, the adhesion of the preliminary sliver 12a to the sliver 12 becomes relatively weak. FIGS. 8 to 11 show a width of 40 I, for example, which is guided separately from one another by separate reversing rollers 30 and moved along the transport direction X by separate drive rollers 23a.
Another configuration of the introduction table 10 with II1 transfer belt l818a is reproduced in detail. Unlike FIG. 1, the drive roller 23a is not provided at the delivery position 11 near the electric a 122, but is instead part of a modular drive unit 25 that includes a unique drive section. The drive unit 25 is located at the retracting end 11 of the substantially horizontal support 38. The support includes a number of support members 38a. 38b and 38c are integrated. In order to establish as many different overall lengths n of the support body 38 as possible, the support elements are used, according to FIG. 8, for example in three different lengths.
The length n1 of the support member 38a corresponds to half the length of the support member 38c, and the length n2 of the support member 38b is equal to 1 of the length n1.
Equivalent to 5 times. Each support member 38a. Each support 38, which is constructed with stepwise overall length n by 38b and 38c, has a common horizontal wire 5.
It is located above 2. The cross beam itself is connected to a vertical support 54. Each support 38, which together with the drive unit 25 and the deflection roller 30 mounted at the other end constitutes a replacement unit, is introduced with a cross beam 52 and a vertical column 54 (the bottom of which is simplified in the drawing). It forms part of the base 56 of the table 10. Lower inter-vehicle portion 18t of the transfer belts 18 to 18a stretched between the direction change roller 30 and the drive roller 23a
is located on the support roller 3l that prevents slack. Support body 38 or support member 38a. 38b. 38c is
According to FIG. 12, a tubular cross-section member 58 that performs a supporting function
A tubular or groove-shaped additional member 60 for accommodating the support roller 3l is coupled to the lower part of the tubular cross-sectional member by rivets or screws. Tubular cross-sectional member 5
A U-shaped cross-section member 62 is located above 8, the legs 64 of which support the transport belt 1 moving in the cross-section space 66.
The groove-shaped additional member 60 is located on the side surface of the upper inter-vehicle portion 18h of 8, 18a to protect the sliver 12 placed thereon, and similarly the groove-shaped additional member 60 protects the lower inter-vehicle portion 18t. The drive unit 25 is connected to the retracting end 11 of the tube section member 58.
It is attached to. F around the drive roller 23a or the sliver 12 placed thereon.
A pressure roller 68 pivotally mounted via a swinging arm is in contact with the console of the support 38 that rotates J tB. A sensor integrated in the drive unit 25 or otherwise arranged in the retraction area controls the movement of the sliver 12 as it runs through. 4. To replace the transfer belt 18.18a, the support 38
is removed from its crossbeam 40 and the variable-position deflection roller 30, which serves as a tension roller, is loosened. After the new transfer belt 18.18a has been fitted, it is tensioned by the deflection roller 30 and the support 38 is reinserted.
