Definitions

  • the invention relates to a sewing machine loading device for automatically loading a sewing machine with first and second sewing parts to be sewn together according to the preamble of claim 1.
  • sewing dresses are required to cover support elements.
  • sewn dresses are used for interior design to conceal basic supports with sewn dresses.
  • the sewn clothes often consist of a plurality of sewn parts in the form of individual fabric, artificial leather or genuine leather cuts, which are joined together by sewing and/or optionally provided with decorative seams.
  • a particular difficulty is that sewing parts (material cuts) with non-congruent contours often have to be sewn in such a way that a three-dimensional Sewing dress is created. This requires the utmost precision on the part of a seamstress when the sewing parts are manually fed to a sewing machine, aligned with one another and sewn. Furthermore, the manual alignment and feeding of the sewing parts to the sewing machine is associated with a considerable amount of time and therefore costs.
  • a sewing machine loading device according to the preamble of claim 1 is known.
  • the device there has two sewing part feeding devices arranged parallel next to one another with first and second storage tables on which first and second sewing parts are arranged.
  • a second sewing part is placed on a first sewing part using a flip device, with the combination of the first and second sewing parts then being transported further to the sewing machine by means of two conveyor belts arranged next to one another.
  • the DE 102018103591 A1 discloses a sewing machine loading device which has a handling device in the form of a robot, which positions the sewing parts removed from two individual magazines and to be sewn one above the other using a suction member.
  • the DE 2644995 A1 discloses a sewing machine loading device with conveying devices for the simultaneous longitudinal feed of two separate sewing parts fed from a sewing part cutting device. The sewn parts are conveyed there on two separate conveyors that converge.
  • the invention is based on the object of creating a sewing machine loading device with which sewing parts to be sewn together can be positioned relative to one another and fed to a sewing machine fully automatically and in the most accurate and rapid manner possible.
  • the sewing machine loading device comprises a handling device for removing the sewing parts from a sewing part magazine or for picking up the sewing parts from a sewing part cutting device, a positioning device for positioning the two sewing parts in a predetermined relative position and a transport device for transporting the sewing parts from the positioning device in the direction of the sewing machine.
  • the positioning device comprises a first storage table with a first storage area for depositing the first sewing part in a predetermined storage position and a second storage table with a second storage area for depositing the second sewing part in a predetermined storage position. At least one of the storage tables can be moved from a first position in which the two storage surfaces are arranged laterally next to one another to a second position in which the two storage surfaces are arranged one above the other.
  • the transport device includes first and second conveyor belts, which are designed to move the two sewing parts on the storage tables.
  • the first and second conveyor belts are vertically spaced.
  • the first The conveyor belt can be moved together with the first storage table between the first and second positions.
  • the first sewing part can be brought into contact with the first conveyor belt and the second conveyor belt with the second sewing part, such that the sewing parts can be transported from the storage tables in the direction of the sewing machine without changing their mutual relative position.
  • the sewing parts to be sewn together can be removed fully automatically from a sewing part magazine or from a sewing part cutting device (cutter) and fed to the positioning device in order to be positioned one above the other in a predetermined manner.
  • the sewing parts positioned in this way are then automatically transported by the positioning device in the direction of the sewing machine without any further change in their relative position by means of the transport device, in particular to a sewing part manipulator arranged on the sewing machine, which continuously aligns the first and second sewing parts relative to one another transversely to the sewing direction during sewing.
  • the sewing machine loading device thus makes it possible for the sewing parts to be sewn together to be handled fully automatically between the sewing part magazine or the sewing part cutting device and the sewing machine or the sewing part manipulator.
  • the handling and positioning of the sewing parts can be carried out very precisely, at high speed and without manpower.
  • a high working speed is achieved in particular by the fact that the handling device immediately returns to the sewing part magazine or can return to the sewing part cutting device and pick up new sewing parts after the previous sewing parts have been placed on the positioning device.
  • the sewing parts can be arranged one above the other in a very precise manner, with the sewing parts preferably only being separated from one another by one of the storage tables. Due to their endlessly rotating belts, the conveyor belts can transport the sewing parts at any time and in a particularly effective manner from the positioning device to the sewing machine or to the sewing part manipulator.
  • the first conveyor belt is a lower conveyor belt and the second conveyor belt is an upper conveyor belt, the first conveyor belt having a conveyor belt section which is arranged in the area of the first storage surface and in a plane parallel to this and protrudes upwards over the first storage surface.
