Description
A method and apparatus for initiating the production of a fibre web to
form a sliver, for example in a carding machine.
The invention relates to a method and apparatus for initiating the production of a fibre web to form a sliver, for example in a carding machine.
In an apparatus described in our British patent application No. 90.17199 filed on 6th August, 1990 (Publication No. 2235472), a roller device, for example doffer, stripper roller, squeezing rollers or the like, is provided, downstream of which there is arranged a web transport device for the collection and further transportation of the fibre web, in which after the web transport device there is provided a conveyor device and in which below the web transport device there is arranged a funnel having a pair of delivery rollers, and in which the web transport device is arranged vertically or at an inclined angle below the roller device, the conveyor device is arranged below the web transport device, the funnel is constructed in the form of a collecting funnel and is arranged below the web transport device and above the conveyor device and the pair of delivery rollers, and the outlet opening of the collecting funnel and/or the pair of delivery rollers are displaceable relative to one another.
The problem underlying the invention is further to improve the apparatus and method described in that application.
The present invention provides an apparatus for feeding a fibre web, the apparatus including a fibre web forming device, a fibre web collecting device and a sliver forming funnel downstream of the fibre web collecting device, wherein the fibre web collecting device comprises a pair of conveyor belts on opposite sides of the fibre path and defining an outlet for the fibre therebetween, the outlet being displaceable in a direction transverse to the path that the fibre takes as it leaves the outlet by pivotal movement of guide rollers, around which the conveyor belts pass in the region of the outlet, about axes spaced from the axes of the guide rollers.
The present invention also provides an apparatus for feeding a fibre web, the apparatus including a fibre web forming device and a fibre web collecting device downstream of which there are provided alternative paths for the fibre web, there being provided along the first path fibre removing means and a conveyor device for conveying fibre discharged from the fibre web collecting device to the fibre removing means, and there being provided along the second path a sliver forming funnel and a pair of delivery rollers downstream of the sliver forming funnel, wherein the fibre web collecting device has an outlet for the web which outlet is displaceable.
The present invention further provides an apparatus for automatically initiating the production of a fibre - 3 web to form a sliver, for example in a carding machine, in which a roller device, for example doffer, stripper roller, squeezing rollers or the like, is provided, downstream of which there is arranged a web transport device for the collection and further transportation of the fibre web, in which after the web. transport device there is provided a conveyor device and in which below the web transport device there is arranged a funnel having a pair of delivery rollers, and in which the web transport device is arranged vertically or obliquely below the roller device, the conveyor device is arranged below the web transport device, the funnel is constructed in the form of a collecting funnel and is arranged below the web transport device and above the conveyor device and the pair of delivery rollers, and the outlet opening of the collecting funnel and/or the pair of delivery rollers are displaceable relative to one another, characterised in that the outlet opening of the web transport device for the fibre web is displaceable.
According to the invention, the delivery point of the fibre material at the end of the web transport device is displaceable. Both in the production initiation phase (start-up operation) and in the operating phase (rapid operation) the fibre material can be delivered vertically downwards. A special advantage lies in the fact that in rapid operation the fibre material is not pulled in obliquely over the downstream input rim of the collecting funnel (funnel edge).
Advantageously, the outlet opening is displaceable in the horizontal direction. Preferably, the guide rollers are each mounted to pivot about a pivot bearing. The guide rollers are preferably displaceable on a curved path. The guide rollers are advantageously connected via guide members to the pivot bearings. The conveyor belts of the web transport device may be tensioned by springbiassed tensioning rollers. One of the guide rollers associated with a conveyor belt may be preferably pretensioned by means of a spring.
The present invention still further provides a method of feeding a fibre web through a sliver forming arrangement in which the fibre is fed along a first path during a first start-up phase of operation and is fed along a second path during a second operational phase, the method including passing the fibre through a fibre web forming device to a fibre web collecting device which has a pair of conveyor belts between which the fibre is guided, wherein the path of the fibre from the fibre web collecting device is changed from the first path to the second path by moving the downstream ends of the pair of conveyor belts in a direction transverse to the path of the fibre by pivotal movement of guide rollers, around which the conveyor belts pass in the region of the outlet, about axes spaced from the axes of the guide rollers.
By way of example certain embodiments of the invention will now be described with reference to the 1 k - 5 accompanying drawings, in which:
Figures la, 1b are end views of a fibre feed apparatus with two conveyor belts each having three guide rollers, the guide rollers being displaceable at the fibre delivery point, when transferring from the start-up phase to the operating phase, is an end view of a modified form of the apparatus of Figure 1 employing two spring-biassed tensioning rollers, and is an end view of a modification with a spring-biassed guide roller.
Figure 2 Figure 3 The apparatus for feeding a fibre web shown in Figs. la and lb is provided on a carding machine which may for example be generally of the kind sold by TrUtzschler GmbH & Co. KG under the trade mark EXACTACARD DK. Such a carding machine has, downstream of the carding cylinder, a doffer, a stripper roller, delivery (squeezing) rollers, a web guide device, a sliver funnel and a can coiling system. The apparatus shown in Figs. la and lb provides the delivery (squeezing) rollers and the web guide device of the carding machine.
Referring now to Figures la, lb, below the delivery rollers 8, there is a web guide device comprising two conveyor belts 50, 51 which revolve about guide rollers 39,', 3911, 39111 and 401, 4011, 40111, respectively.In the 1 - 6 start-up phase of the machine, the guide rollers 39111 and 40111 are displaced approximately horizontally to the left and are in the position shown in Figure la, whilst in the operating phase, the guide rollers 39111 and 40111 are arranged vertically below the guide rollers 391, 401 in the position shown in Figure lb. The guide rollers 39111, 4011 in the start-up phase (Figure 1a) are displaced in the horizontal direction in the operating phase (Figure 1b) in such a 'manner that they are arranged vertically below guide rollers 391, 401. As a result the gap 52 and the outlet opening 52a between the conveyor belts 50, 51 instead of extending at an inclined angle then extend vertically. The pre-sliver F is delivered vertically downwards from the outlet opening 52a both in the start- up phase and in the operating phase. In the start-up phase the pre-sliver is delivered to a conveyor device vertically below the opening 52a and then passed to a removal device, while in the operational phase the presliver is delivered to a sliver funnel which is verti- cally below the outlet opening 52a.
The guide rollers 39"', 40111 at the outlet opening 52a are pivotally mounted by means of guide members 62, 63 pivoted on fixed pivot bearings 60, 61, respectively.
The guide rollers 39111, 40111 can be arranged to act simultaneously as guide rollers and tensioning rollers for the conveyor belts (for example by making the members 62, 63 telescopic and spring- biassed towards an elongated form), a separate tensioning device then being 1 k 4 unnecessary.
In the modified arrangement of Figure 2 each conveyor belt is associated with a tensioning roller 66, 67 biassed by a spring 68, 69, respectively. When the guide roller moves in the direction of arrow 64 from position 39111 into position 39al" shown by dotted lines, or conversely in the direction of arrow 65 from 39al" to 39111, optimum tensioning of the belt is ensured. In a structurally advantageous manner that has spatial 10advantages the separating bearings 60, 61 (only 60 being shown in Fig. 2) are arranged in the region between the guide rollers 391, 39111 and 401, 401".
In the modified arrangement of Figure 3, the outermost guide roller 3911, 4011 (only 4011 is shown) is pretensioned by a spring 70, 71 (only 71 is shown). The reference numeral 72 indicates a drive device, for example a drive motor which drives the guide roller 401 and hence the belt 51. The drive roller 39, and belt 50 may be similarly driven.
In Figures 2 and 3, the function of the guide rollers 39f", 40111 lies only in the guidance of the conveyor belts 50, 51, while the pretensioning of the conveyor belts 50, 51 is effected by the tensioning springs 68, 69 and 70, 71.
The apparatus described above is similar to the apparatus described in our patent application No. 90.17199 filed on 6th August, 1990, the description of which is incorporated herein by reference.
