Definitions

  • the invention overcomes this drawback and in particular aims to provide a sheet part handling device which does not require such adjustments.
  • this object is achieved, in accordance with the invention because one of the gripper elements, known as the first element, forms a blistering device intended to blister on a zone, known as blistering, of the part by resting on a zone of the latter surrounding, at least partially, the blistering zone, while the means for moving the gripper elements are arranged to move the other gripper element , relative to the first element, in a direction parallel to the extension of the part to be handled so as to pinch said part at the level of the blister, between the clamp elements.
  • the process of gripping and lifting the part to be handled takes place in the following manner: the first clamp element is first applied with a certain pressure on this part. Then, this first element being kept fixed in abutment on the part, the second element is moved towards the first element in a direction substantially parallel to the extension of the part to be gripped, that is to say in a substantially orthogonal direction the pressing force of the first element on the part to be gripped.
  • the following two movements: (1) movement of applying the first element to the workpiece and (2) movement of bringing the clamp elements closer to one another, can thus, thanks to the invention, be separated in the time. It follows that the initial value of the width of the space remaining between the two clamping elements at rest, that is to say before their mutual approximation, should not be adjusted to a precise value defined according to the characteristics of the room to grab.
  • the two gripper elements are supported on the part to be handled, by bearing surfaces of different values: the bearing surface of the first element being greater than that of the second element.
  • the second element is movable relative to the first element between, on the one hand, a first position for which this second element is spaced from a so-called pinching part of the first element and, on the other hand, a second position for which the second element is biased towards said gripping part so as to pinch the part at the level of the blister between the second element and the pinch part.
  • the first element is arranged to press the part on an area surrounding the blistering zone only on three sides and said pinching part is the part of the first element coinciding with the side of the blistering zone opposite to the free side of this zone.
  • the device further comprises: means for holding the part on the support in a zone, called a holding zone which is spaced from the blistering zone, and which is preferably situated at one end of the part, these holding means pressing this area between a pressing member and the support, and means for applying a force substantially coplanar with the workpiece and directed away from the holding area on the gripper body and for moving said body away of said support.
  • the first gripper element bears on the part to be handled by a so-called pressing wall, provided with an opening, one of the sides of which, said gripping side, is intended to cooperate with the other gripper element, and this last element is a finger which is engaged in said opening and which is mounted on the clamp body movable relative to said wall between a first position for which it is spaced from said nip side and a second position for which it is applied with some pressure, against the pinch side.
  • At least one upper extreme layer of the support is elastically compressible.
  • the part to be gripped is the upper part of a stack of sheet-shaped parts, flexible and elastically compressible, resting on the support.
  • the opening of the pressing wall has an elongated shape and the nipping side coincides with an extreme edge of this opening.
  • the pressing wall only defines said opening on three sides, the central side of which coincides with the nipping side.
  • the handling device shown comprises a frame 1 on which is mounted a flat, horizontal support 2 for a stack 3 of pieces of fabric to be handled.
  • the parts 9, 9a, 9b are knitted fabric briefs, but the invention extends to the handling of all parts in flexible, compressible sheet and, more particularly, in sheets having in addition, some stretch such as knitted pieces.
  • Each clamp 5, 6 comprises a clamp body 10 of vertical planar shape ending downwards by a flat, horizontal pressing sole 11, extending towards the adjacent edge 12 of the part 9 the sole 11 is provided with a opening 13, for example rectangular, whose long sides 13a are perpendicular to the clamp body 10.
  • On the clamp body 10 is horizontally guided a vertical plate 14, parallel to the clamp body 10 and ending downwards by a finger 15 engaged in the opening 13 of the sole 11.
  • the plate 14 is fixed to the free end of the rod 16 of the piston 17 of a single-acting cylinder 18, with return spring 19, cylinder 18 whose axis is horizontal and the housing 18a of which is fixed to the gripper body 10 and projects from the face 10a of said gripper body opposite the sole 11.
  • the clamp body 10 is mounted on a vertical support 20 integral with the piston 21 of a cylinder with a vertical axis 22, the casing 22a of which is fixed to the element of structure 4, this jack 22 being single acting and having a return spring 23.
  • the support 2 is advantageously elastically compressible as shown in Figure 5; thanks to this characteristic, the formation of blisters 24 is facilitated for the last part 9b of the stack 3.
  • FIG. 7 shows another embodiment of a clamp 5, 6.
  • the opening 13 of the pressing sole 11 is surrounded by the latter only on three sides, the fourth side 13b being located opposite the extreme front side 13c.
  • This embodiment allows gripping sheets having low extensibility, such as woven fabrics.
  • the clamps 5, 6 of the device which has just been described are of simple design and do not require any particular member to be separated from the gripped part; a simple discharge of the pressure chamber 18b of the jack 18 causes the clamp to open, opening which causes the release of the part without delay.
  • the advancing movement (f 4 ) of the plate 14 corresponds to the movement of the finger 15 along a trajectory substantially coinciding with the longitudinal axis of the opening 13 which is of elongated shape.
  • the length of the finger part 15 engaged in the opening 13 is chosen as a function of the type of sheet 9, 9a, 9b to be gripped, so that during the movement of advance of said finger 15, the underlying part 9a is also not pinched between the elements 11 and 15 to the point of not being able to be released during the simultaneous movements (f 2 ) and (f 3 ) of the clamp.
  • any other means of moving the movable finger 15 could be used without departing from the scope of the present invention; in particular, an electromagnet could be used for this purpose.
