Definitions

  • the present invention relates to a plant for supplying yarn to a loom and comprising a yarn rack, which is placed next to the loom and which comprises a number of juxtaposed, replaceable carriers that are suspended by means of carrier rolls in a ceiling rail arrangement and on which yarn spools are suspended.
  • the invention further relates to a method for supplying yarn to a loom from a yarn rack, which comprises a number of juxtaposed, replaceable carriers that are suspended by means of carrier rolls in a ceiling rail arrangement and on which yarn spools are placed.
  • the present description discusses the supply of yarn to a loom. However, the plant may also be used for supplying yarn to other machines, e.g. knitting machines.
  • Yarn racks may be fixed installations in which the yarn spools are placed on a fixedly mounted yarn rack and in which the replacement of the yarn spools is effected directly in the yarn rack, which is positioned in immediate vicinity of the loom.
  • yarn rack requires much space.
  • the yarn spools are normally mounted in the yarn carriers on pins projecting on either side. A large number of pins are mounted one over the other which means that the carrier will have an elevated centre of gravity. This leads to a risk that the carrier may overturn. This risk is particularly distinct if the carrier is only provided with yarn spools on one side. Furthermore, the actual handling of the carriers is hard work, and when replacement of the carriers is done, there will be a risk that a carrier is placed in a wrong position in the yarn rack. Then the goods formed on the loom will be useless.
  • So-called double racks are known as well. These are yarn racks having two receiver pins/yarn spools for each yarn to be fed to the loom. In these racks an operator will transfer around in the very yarn rack removing the empty yarn spools and inserting the full ones. This leads to wind transfers, which may cause the yarns in the rack to become entangled with each other. Due to this a situation arises in which the loom has to be stopped.
  • US patent No. 3,602,456 discloses a plant having a ceiling rail arrangement by means of which replaceable yarn carriers may be moved into a number of branch rails via a main rail.
  • the carriers with yarn spools are entered into the main rail via the branch of the main rail.
  • the storage station is located at a long distance from the feeding station or the yarn rack, and when the carriers are moved along the main rail, there will be a risk of misplacing carriers on wrong branch rails.
  • the yarn rack comprises a feeding station having a number of juxtaposed rails, each of which is able to carry one or more carriers, said feeding station being placed in immediate vicinity of the loom, as well as an adjacent storage station, which is connected with the feeding station via the rail arrangement and which comprises at least two related rails for each rail in the feeding station.
  • the method according to the invention is characterised in in that the yarns are unwound from the spools while each carrier is located on a rail of its own in a feeding station in immediate vicinity of the loom, that when the yarn spools have been emptied, the carriers are transferred via the ceiling rail arrangement from the rail in the feeding station to a first related rail in a storage station, that a carrier with full yarn spools is transferred from a second related rail in the storage station onto said related rail in the feeding station for subsequent supply to the loom.
  • the ceiling rail arrangement further makes it possible to ensure that carriers are always placed in their correct positions in the feeding station of the yarn rack.
  • the ceiling rail arrangement it is possible in a simple manner to construct a mechanically simple plant.
  • the rail arrangement may be constructed from rail units known per se and having switches for guiding carriers correctly between the different stations of the plant.
  • Such switch points may be operated manually by the operator who replaces the carriers in the yarn rack.
  • the switch points may be traditional type ones activated mechanically, electrically or pneumatically.
  • the rail arrangement always connects a yarn rack feeding station with the corresponding nearby storage station, there will be no risk of misplacing carriers in the feeding station. Since the feeding station and the storage station are close to each other, the replacement may take place very quickly.
  • the loom only has to be stopped for the time in which the yarns are cut, the row of carriers is transferred from the feeding station to the storage station, and during the subsequent introduction of new carriers and splicing of yarn ends of the loom with yarn ends of the full spools.
  • Fig. 1 shows a schematic view of a plant 1 according to the invention.
  • Fig. 1 illustrates schematically the structure of the plant.
  • a number of details that will be within the skilled person's option in the light of the description have not been included in the figure.
  • a number of looms 2 are shown in Fig. 1, which are supplied with yarn from the yarn rack 3 of the plant 1.
  • the yarn rack 3 comprises a number of juxtaposed carriers 4 (see Fig. 2), on which yarn spools 5 are suspended.
  • the yarn rack has a feeding station 6 positioned in immediate vicinity of the looms 2, and an adjacent storage station 7.
  • the carriers 4 are suspended by means of carrier rolls 8 (see Fig. 2) in a ceiling rail arrangement 9.
  • the rail arrangement 9 may be mounted on a number of posts or be suspended in the ceiling.
  • the ceiling rail arrangement 9 in the feeding station 6 comprises a number of first rail lengths 10 for each loom 2. In the embodiment shown there are four first rail lengths 10 for each loom 2. For each of the juxtaposed first rail lengths 10 in the feeding station 6 there are at least two second rail lengths 11 in the storage station 7. In the embodiment shown there are three second rail lengths 11 for each first rail length 10.
  • the rail arrangement further comprises a central rail length 12. Each of the second rail lengths 11 is connected by means of switch points 13 and the central rail length 12 with the corresponding first rail length 10. It is thus possible to transfer the carriers 4 between different stations in the rail arrangement.
  • a row of carriers 4 is indicated by 14, which carriers 4 are suspended in a first rail length 10.
  • Each row 14 comprises preferably four to six carriers of the type shown in Fig. 2. These carriers occupy a width 15 when supplied with yarn spools 5.
  • the width 15 comprises the width of the full yarn carrier 15' itself which is approximately 700 mm, and a free space 15'' of approximately 400 mm on either side of it in order to ensure unhampered unwinding of the yarns, which are fed to the loom in traditional manner via a pipe system (not shown) on either side of the row 14 of yarn carriers 4.
  • each carrier 4 there will be a distance or a passage area 16, which only has to be wide enough for an operator to be placed between the yarn carriers in order to perform the necessary operations of cutting and splicing yarns in a manner known per se during replacement of the yarn spools.
  • This distance will preferably be between 700 and 800 mm, preferably around 800 mm. This is a space saving of about 20% compared to traditional plants in which an operator must also be able to bring a trolley for replacement of yarn spools.
  • the rail arrangement 9 connects the yarn rack 3 via the central rail length 12 with a filling station 17, in which full yarn spools are placed in the carriers.
  • the yarn rack 3 is likewise connected with an emptying station 18, in which spools with any remaining yarn are removed from the carriers 4.
  • the plant 1 is optionally connected with a computer unit (not shown) controlling the transfer of the carriers 4 between the different stations as well as the settings of the different switch points 13 when the carriers are transferred on the rail arrangement 9.
  • the plant may be supervised manually, and the transfer of carriers 4 between the different stations will then be accomplished by the operator setting the switch points 13 according to requirements.
  • the switch points may be set by means of electric, pneumatic or mechanical actuators, which will be known to a person skilled in the art.
  • Figs. 2 to 5 show different details of the plant 1 as well as the carrier 4.
  • the carrier rolls 8 comprise wheels 19 rotating around substantially horizontal axles 20. It is seen in Fig. 4 that the rail arrangement comprises a substantially C-shaped profile having an opening 21 at its downward side. A connection flange 22 for the carrier roll 8 passes through the opening 21. The connection flange 22 is connected with an upper carrier profile 23 forming part of the carrier 4.
  • Each carrier profile 23 in the embodiment shown is provided with four vertical posts 24. Alternatively, a larger number of posts may be used, e.g. up to eight. At their bottoms the posts 24 are connected by means of a lower support profile 25. Mounted at the underside of the lower support profile 25 are guiding rolls 26 rotating around substantially vertical axles.
  • the guiding rolls 26 co-operate with a floor rail 27, which is intended to be placed at least in the feeding station 6 of the yarn rack 3 under a corresponding first rail length 10. This provides secure vertical orientation of the carriers when they are placed in the feeding station. This is important in respect to correct unwinding of the yarns from the yarn spools 5.
  • the floor rail 27 has the shape of a funnel 28 so that the guiding rolls 26 will easily get into correct engagement with the guiding rail 27.
  • Each of the vertical posts 24 is provided with a number of pins 29 arranged one over the other.
  • the pins 29 project to either side of the carrier, as appears from Fig. 3.
  • eight pins 29 are arranged one over the other on each vertical post 24.
  • a total number of sixteen yarn spools 5 may be placed on each post.
  • the pins 23 extend perpendicularly to the vertical posts 24.
  • the loom 2 is stopped. Then the yarn ends are cut, so that loose yarns ends are hanging from each of the pipes supplying the loom 2 with yarn from the feeding station 6.
  • the switch point 13 is set so that a first rail length 10 in the feeding station 6 is connected with one of the corresponding second rail lengths 11 in the storage station 7. Then the row of carriers 4 with empty yarn spools 5 is transferred onto said corresponding second rail length 11. Then the switch point 13 is shifted so that one of the other two of the second rail lengths 11 in the storage station 7 is connected with the corresponding first rail length 10 in the feeding station 6. The operator repeats this for de four first rail lengths belonging to the loom 2. Then the yarn ends of the full yarn spools 5 are spliced with the yarn ends of the loom. Then the loom may be restarted.
  • the second rail lengths 11 may be provided with colour codes.
  • the operator may transfer the carriers 4 via the central rail length 12 to the emptying station 18 where yarn spools 15 with any remaining yarn are removed from the carriers 4. Then the carriers are transferred to the filling station 17 where new yarn spools are placed in the carriers. When this has been done, the carriers may again be transferred via the central rail length 12 into the storage station 7 of the yarn rack 3 on a correct second rail length 11.
