Definitions

  • the present invention relates to an apparatus for loading and replacing piece goods, or fabric rolls, effective to be associated with spreading machines of the type used in the clothes field.
  • suitable spreading machines comprising an equipped turret effective to longitudinally slide along a table and bearing the piece to be spread.
  • the GB Patent 2,023,201 discloses an apparatus for tentering clothes including a single fabric laying reciprocable carriage carrying the rolls of fabric to be deposited on a bench in tentered form, which carriage carries out both the fabric loading and unloading operations.
  • a single carriage the operation of the apparatus is rather slow, with a consequent poor tentering efficiency.
  • the task of the present invention is that of overcoming the thereinabove mentioned drawbacks by providing an apparatus for loading and unloading fabric rolls onto spreading machines, and able of carrying out the mentioned roll loading and unloading operations in a fully automatic way, that is without any manual processings, and with a high efficiency.
  • Yet another object of the present invention is to provide an apparatus for loading and unloading fabric rolls which is effective to discharge the empty mandrel from the spreading machine and load a new piece according to a predetermined program.
  • Yet another object of the present invention is to provide an apparatus for loading and unloading fabric rolls which is effective to be associated with any spreading machine presently available.
  • the movements of the piece bearing carousel and of said carriages are controlled by programming means effective to preset the movements of the fabric rolls to be supplied, by causing said rolls to be displaced to the loading carriage end of stroke position.
  • the carousel is driven in such a way as to bring the roll being spread balance supporting member to the proximity of the end of stroke position of the discharging carriage.
  • the apparatus for automatically loading and replacing piece goods effective to be associated with piece spreading machines, according to the present invention, comprises a vertically extending magazine or carousel 1, formed by two shoulders at the top and bottom portions thereof there are provided rotating gear wheel sets or assemblies 2, driven by a geared motor 3 through a driveshaft 4 and suitable transmission gear pairs 5.
  • the mentioned gear wheel sets are engaged with correspondng chain members 6 bearing, at even spacings, balance supporting members 7, effective to support the mandrel 8 in turn supporting the piece goods 9.
  • a piece loading device 10 comprising two shaped shoulders 11, whereon there are provided two guide pairs 12 and 12', 13 and 13' respectively, which guides are differently slanted with respect to the horizontal direction and converging toward said shoulder edge opposite to said carousel.
  • corresponding carriages 14 and 15 are capable of sliding as driven by chain members indicated respectively at 16 and 17, which extend between end gear wheel pairs 18 and 18', 19 and 19'.
  • gear wheel pairs 18 and 19 are driven through chain members 20 and 21, by pignon pairs 22 and 23, coupled by transmission or driving shafts which latter are in turn driven through respective chain members 24 by corresponding geared motor sets 25.
  • the mentioned carriages 14 and 15 are provided with an elongated arm member, indicated respectively at 14' and 15', along one edge thereof a chain 2b is capable of sliding being affixed, at an intermediate point, 27, to a small bracket 28 rigid with one of the mentioned guides 12 and 13.
  • Said chain 26 in particular, bears two adjoining projecting small plates 29 which define an intermediate seat or housing 30 effective to receive one of the ends of the mandrels 8 bearing the piece goods.
  • Said small plates owing to the chains being affixed at 27, are able of moving, jointly to the carriages 14 and 15, from one end to the other of the carriage arm members 14' and 15'.
  • the mentioned small plates 29 are able of alternatively approaching one of the balance supporting members 7 of the carousel, and suitable supporting members 31 comprising roller pairs, one thereof is controlled for laterally moving, said rollers being supported by the movable turret or slide of a known piece spreading machine.
  • the mandrel of the first piece is located at the upper guides of the piece loading device, whereas the carriage 14 locates its arm provided with the small plates 29 in such a position as to be able of receiving said mandrel.
  • the carriage 14 is driven in such a way as to bring said small plates to the opposite end of its arm, thereby discharging the piece on the turret of the piece spreading machine.
  • the carousel will have brought the second piece to be spread (as per program) to such a position effective to supply the piece loading device.
  • the carousel rotates to bring the balance supporting member 7 supporting the piece being spread to the guides 13 and 13'.
  • the carousel brings the subsequent piece to be spread at the guides 12, 12' in such a way as to load the carriage 14 again, which afterwards, will wait for the discharging of the second mandrel from the turret of the piece spreading machine.
  • the carousel rotates in such a way to locate said second mandrel balance supporting member at said guides 13 and 13' and so on.
