Definitions

  • This invention concerns a system to handle and store woven piece goods. To be more exact, the invention concerns a system able to remove woven goods produced on looms, to convey them to appropriate storage zones and to store them thereafter in temporary storage.
  • the system of the invention can be applied to any weaving shed where woven piece goods are taken up on traditional cloth rollers on the looms.
  • the system will operate disadvantageously, but not only, in coooperation with the department that inspects the woven goods downstream of the looms.
  • the woven products are run on appropriate apparatuses where their suitability as regards quality is inspected; they are then wound up to form a finished product or a product ready for further treatment.
  • the present applicant has designed, tested and embodied a system for handling and storage of woven piece goods which is suitable to overcome all the drawbacks of the state of the art.
  • the system according to the invention provides for the inclusion of movable means able to run through the weaving shed independently, these movable means being advantageously of a type guided by a magnetic wire.
  • the movable means are equipped to unwind automatically from, and at the side of, the looms the woven products wound on the cloth rollers and thus to empty the full cloth rollers and make them suitable for another weaving step.
  • the unwound woven product is taken up on a support borne by the movable means and capable of being fully analogous to the cloth rollers of the looms.
  • the movable means are summoned advantageously to the looms which require tending, and follow pre-set and pre-determinable paths between the looms and a zone for storage of such supports full of woven products taken from the looms.
  • the movable means cooperate with means which unwind the woven products from a full support and rewind it on available analogous empty supports.
  • the full support on the movable means is unloaded in the storage zone and an empty support is loaded thereafter on the same movable means.
  • the storage zone provides for temporary storage of the full supports before use of the latter in the equipment used for inspection of the prepared woven goods.
  • the storage period and the number of full supports being temporarily stored will normally depend on the daily working period of the looms and of the inspection equipment and will therefore provide also for a possible buffer stock.
  • Means to handle and store empty supports will also be included in the storage zone, such empty supports waiting to take up woven products from the looms or else to be loaded on the movable means according to the variant cited above.
  • the system according to the invention provides a plurality of advantages, particularly as regards the labour force required, transport, overall working times of the cycle and the space taken up together with the relative savings of costs.
  • Fig.1 gives a diagram of a weaving shed 10 holding a plurality of looms 11, which are arranged in this example in such a way as to have their sides discharging the woven product facing each other.
  • One or more of the movable means which are advantageously trolleys 13 of a type guided by a magnetic wire, can run along the runways 12.
  • Each trolley 13 is equipped with devices able to converse with each loom 11 so that it can be summoned and directed as required.
  • the trolley 13 can halt conveniently immediately upstream of a zone 14 for temporary storage of woven products taken from the looms 11, this storage zone 14 in turn being located immediately upstream of a zone 15 for inspection of the woven products.
  • Figs.2 and 3 show diagrammatically one form of embodiment of the trolley 13, which consists of a frame 16 able to move on wheels 17.
  • the frame 16 comprises casing means 18 to hold the drive means and motion transmission means, and also actuation means, such as sets of batteries and other devices.
  • the trolley 13 travels on runways 12 in the direction of its lengthwise development and is halted at the loom 11 which has summoned it in the vicinity of the full cloth roller 19.
  • Fig.3 shows an example, with lines of dashes, of possible full cloth rollers 19 on two facing looms 11; in Fig.3 the trolley 13 is shown in an enlarged front view for illustrative purposes.
  • the trolley 13 is equipped with a pair of oscillatory arms 20, which are conformed to bear a cloth support 21 and to position the same 21 by means of a suitable angular displacement 22 (positions shown with lines of dashes in Fig.3) in its working position against a full cloth roller 19 of the loom 11.
  • This angular displacement 22 is obtained by suitable motor means in the casing 18, these motor means not being shown in the figures.
  • the cloth support 21 is connected to a drive means 23, which rotates the support 21 about its axis according to the arrow 24 whenever the support 21 is brought into contact with a full cloth roller 19.
  • the trolley 13 is therefore able to remove the prepared cloth from the loom 11 and to enable the loom 11 to start a new weaving step.
  • Fig.4 gives a diagrammatic side view of a temporary storage zone 14 and a connected zone 15 for inspection of woven products.
  • the trolley 13 returning from a travel in the runway 12 is brought to a cloth unwinding zone 26, in which suitable unwinding means 27 unwind the woven cloth from the support 21 on the trolley 13 and wind it on an analogous support 21 borne by the unwinding means 27.
  • the trolley 13 therefore holds an empty support 21 and can return to the weaving area, while the full cloth packages 28 are discharged onto a buffer storage unit 29 suitable to accommodate a plurality of such packages 28.
  • the buffer storage unit 29 may be a conveyor belt, roller conveyor or another means suitable to feed a plurality of adjacent packages in succession.
  • the trolley 13 discharges directly onto the buffer storage unit 29 the woven cloth support 21 with the layer of wound cloth 25 thereon and is loaded with a fresh empty support 21, as will be made clearer hereafter.
  • the looms 11 may work three shifts, whereas the inspection department 15 may work only one shift, and it will be possible to have available a storage zone 14 of a size able to accommodate the output of at least two shifts of the looms 11.
  • One or more machine operators 31 are usually present in the inspection zone 15 and are able to take the wound cloth packages 28 from the movable store 30 so as to feed an inspection apparatus, which is normally a winding machine 32; this removal of packages 28 from the store 30 may also be of an automatic type.
  • the removal of packages 28 from the movable store 30 by the machine operator 31 may take place at any position of the movable store 30 without impairing the continuity of feed to the winding machine 32 and with advantage to the working methods of the operator 31.
  • the winding machine 32 winds the inspected woven cloth on final packages 33, while the empty support 21 of the unwound packages 28 may be put advantageously onto an endless circuit 34 able to carry and deliver the empty supports 21 to the cloth unwinding zone 26 so that one of the supports 21 can be automatically engaged and used by the unwinding means 27.
  • the empty cloth supports 21 are loaded directly in the unwinding zone 26 onto the movable trolley 13 on arrival there of the latter 13.
