Definitions

  • the present invention relates to a method of positioning a flexible sheet piece such as a piece of fabric, on a support surface.
  • the invention also relates to a handling installation for implementing this method.
  • the object of the invention is to propose a method of easy implementation, making it possible to automatically deposit, on a receiving support, in a predetermined position, a flexible sheet piece taken from a storage support where said flexible piece has been previously deposited in an approximate position.
  • This object is achieved in accordance with the invention, due to the fact that two so-called alignment points are defined on the support surface, that the part is gripped on the storage medium, by at least two so-called gripping points, the part, spaced from each other and preferably situated along an edge of the latter, these points are displaced along trajectories which are substantially parallel to each other and extending above the support surface so that at least one end of the part drags on this surface, and each of said gripping points is released, independently of one another, as soon as a remarkable line of the part passes through a point of respective alignment of the support surface, each alignment point being situated substantially at the level of the trajectory of the corresponding gripping point.
  • This method is advantageously implemented in a handling installation which is characterized, in accordance with the invention, in that it comprises a frame on which are mounted a storage support for at least one flexible piece in sheet form, a device for reception having a reception surface for receiving a flexible part, and a gripping and transfer device for gripping at least two points, spaced apart from each other, of a part on the support to move these points to the -above the receiving surface so that one end of said piece drags on this surface and to release independently of each other, each of these points as soon as a remarkable line of the piece passes through a point respective, said alignment point, of the receiving surface.
  • This remarkable line is, for example, the free edge itself of the part, free edge delimiting said trailing end of the part.
  • the alignment points are fixed relative to the frame.
  • the reception device is the movable member of a transfer device between a first and a second station.
  • the movable member of the transfer device is substantially transparent and the alignment points are materialized by optical detectors, placed under said receiving surface.
  • the gripping and transfer device comprises means for successively gripping the upper part of the stack, by its end, called the gripping end, situated opposite the first station of the transfer device, for lifting this end d 'a certain height, to move this end above the rest of said upper part in the direction of the first station of the transfer device, so as to form a fold on this part making it easier to take off from the underlying part, and to continue the movement of said end above the reception surface of the reception device until 'that said remarkable line passes through said alignment points.
  • a free space is provided between the support and the transfer device to allow the unfolding by gravity of the part gripped by the gripping and transfer device.
  • the gripping and transfer device comprises first gripping means for gripping the gripping end of the workpiece and lifting it from a certain height, and, second gripping means for gripping this raised end and for moving it up to the plumb of the receiving surface of the receiving device.
  • the installation according to the invention thus makes it possible to carry out both the transfer and the positioning, one by one, of each of several pieces stacked in approximate positions on the storage medium.
  • This installation thus advantageously finds application in the automatic feeding of a sewing station such as, for example, a colleting station, a stitching machine, an overlocker, etc., in a piece of fabric whose finishing requires several passages in a sewing station.
  • a sewing station such as, for example, a colleting station, a stitching machine, an overlocker, etc.
  • the handling installation shown comprises (FIG. 1) a frame 1 on which are mounted a horizontal plane support 2 for a pile 3 of pieces of fabric such as pieces of underpants 4, first gripping means for gripping and lifting from a certain height one end 5 of the upper part 4a of the stack 3 (FIG. 2a), and of the second gripping means designed for:
  • the receiving support 8 is a circular transfer table, mounted on a bearing 26 of the frame 1 to rotate about its vertical axis 8a, and associated with motor means for its drive in rotation around the axis 8a.
  • These drive means are constituted by a friction roller 27 applied to the table 8 and driven in rotation from a motor 28 ( Figure 3).
  • the rotary table 8 is made of a transparent material and two optical detectors 29, 30 are arranged under the table 8, each at a fixed point of the frame 1.
  • the table 8 is located upstream of a fixed table which is coplanar with it 31 and which is the table of a colleting station 32 shown diagrammatically in FIG. 3, station in which a flange - or strip - is fixed by sewing along the concave selvedge B 'C' of a piece of underpants 4.
  • the present installation automatically picks up one by one the articles 4 stacked at station 19.
  • the panty pieces 4 are, at station 19, approximately stacked on each other and have positional deviations as shown in FIG. 5.
  • FIG. 3 shows that the gripping means 9, 10 grip the pieces 4 at the edge ABCD; after the article 4 has been turned over by the flattening carriage 16, the selvedge which will in fact be worked on the colleting station 32 will be the selvedge A ', B', C ', D'.
  • FIG. 2a shows the flattening carriage 16 advancing (arrow f 2 ) towards article 4a held in the grippers 9, 10.
  • FIG. 2b shows the phase of detachment by turning over the part 4a which is separated from the other parts 4 of the stack 3 without displacing the latter by moving the carriage 16 in the opposite direction (arrow f 1 ).
  • FIG. 2d shows the flat deposition of the part 4a on the rotary table 8.
  • the two detectors 29, 30 placed under the turntable 8 each trigger, on passing the selvedge side, respectively D'C 'and B'A', the opening of the corresponding clamp 21, 22, which makes it possible to release the 'article 4a in a relatively precise position on the table 8 and at least partially correct its starting position from the stack 3.
  • This principle makes it possible to orient the edge A'B'C'D' according to a predetermined orientation by relative to the fixed seam line 32b (FIG. 1) of the colleting station 32. This orientation constitutes a necessary step for the correct presentation of the selvedge B'C 'of the sewing machine of said station 32.
  • the carriage 1 6 stops and starts again towards the next article 4b, the gripping of which is in progress.
  • the rotary table 8 rotates 180 ° to transfer the part 4a to a next station 35 where the edge A'B'C'D'est under the pads 36a in the upper position of a hat 'transfer riot flat 36 movable between the position 35 and position 32.
  • the role of the table 8 is to provide the relay between the second gripping means 16, 21, 22 and the carriage 36 which transfers the article 4a to the sewing machine 32a of the station 32. It receives the pieces of panties 4 coming from of the approximate stack 3. These pieces 4 are placed one after the other in the table part 8 located at station 20 while the preceding article 4 is lying flat on the other half of table 8 au- above which the return end position of the carriage 36 is located. The nats 36a of the carriage 36 are applied to the part 4a of the station 35 and this part is taken by the carriage 36 to the sewing machine of the extension 32.
  • FIG. 6 shows the diagram of the control circuit for the grippers "21, 22 of the flattening carriage 16.
  • the pneumatic cylinder 25a, 25b associated with each gripper 21, 22 is controlled from: (a) a signal which is emitted by the corresponding detector 29, 30 when the so-called reference selvedge, C'D ', A'B'corresponding passes over the latter, and (b) of a signal emitted by a limit switch 37 when the carriage 16 is in its end of travel position at the station 19.
  • each jack 25a, 25b is supplied with compressed air from a source 38 via a distributor respective of the four-way two-position type 39a, 39b.
  • the clamp 21 is opened by putting the actuator 25a in the deployed position due to the switching of the distributor 39a to its position 40 putting the chamber 41 of the jack 25a under pressure and putting the other chamber into the atmosphere e 42 of this jack 25a.
  • Closing the clamp 21 is obtained by placing the actuator 25a in the contracted position, this positioning being achieved by switching the distributor 39a to its position 43 for which the chamber 42 is pressurized and the chamber 41 vented.
  • the control of the other clamp 22 takes place according to the same process, by replacing, in the description of operation given above, the detector 29, the detector 30, the jack 25a, the jack 25b, and the distributor 39a, the distributor 39b.
