Definitions

  • the subject of the present invention is a form for producing shoes.
  • a part called shape which very schematically simulates the shape of an individual's foot.
  • This form is used to receive the part of the shoe called upper, for the purpose of shaping the same and different assembly operations for placing the ends of the shoe, carding operations, welding, assembly of a sole, or injection of a sole.
  • a shape is made up of a part monolithic made of solid synthetic material, in particular resin, or metallic, if it is necessary to heat the shape for certain shoe-making operations.
  • a handling device also called a gripper, which allows the shape to be taken, for example, using the end of the arm from a robot, to transfer this shape to another robot, or to a station of work.
  • a first drawback of such a form is that it is monolithic. Therefore, it is undeformable, which makes it difficult to put in place of the uppers on the form, as well as removing the shoe out of the form.
  • each form is equipped with a gripping device.
  • Each shape having dimensions specific to a size and a type of shoe, a manufacturer should have a very large number of forms, and as many gripping devices, which leads to high investment. This investment is poorly valued, since all available forms cannot be used at the same time.
  • the object of the invention is to provide a shape which allows facilitate the operations of placing and removing the rod, while having excellent rigidity allowing robotic manufacturing of shoes.
  • the shape it relates to includes a framework rigid unit equipped with a gripping device or gripper protruding from the shape, this orientation framework substantially perpendicular to the longitudinal axis of the form having a first part integral with the gripper and intended to receive removably but using a rigid attachment, a component part of the shape, front or rear, and a second part which, sliding mounted on the first part in a sense of distance from the gripper, with possibility pivot at the end of the travel distance, is intended to receive removable but with a rigid attachment a component of another part of the form, respectively rear or front part.
  • the second part of the framework of the form is pivotally mounted on the first part, in a direction of approximation of the toe and the heel.
  • the structure of the frame allows movement important between the front part and the back part of the shape, and so bring the toe and heel closer, which makes operations easier for installing and removing the rod.
  • this structure allows mounting on the same frame different types of rods, which is a very economical sensitive. It is enough for an industrialist to have a certain number grippers equipped with a framework, and to mount the forms thereon used to make one type of shoe. So the number of grippers and frameworks can be significantly less than the number of shapes. It can also be noted that the framework being rigid and made in a material such as steel, strengthens the shape, the structure of which can be lightened compared to the structure of traditional forms. This relief translates into another economy in the manufacturing of shapes.
  • the first part of the framework integral with the gripper, is constituted by a profile
  • the second part of the framework consists of a shaped section profile general of C, guided in translation and in rotation on the first profile.
  • the first profile comprises, close to its ends, two sets of fingers intended to be engaged in the grooves the second C-profile, to guide it, the second profile comprising in the grooves that it has two stops to limit the release of the second profile out of the first profile.
  • each part of the frame has turned fingers forward and backward respectively for receiving coins constitutive of the form, which have complementary cavities. This fixing is carried out by wedging.
  • each finger has a diametrical slot and an axial threaded hole intended for receive a screw allowing the finger section to be perfectly adjusted to the section of the corresponding cavity.
  • the shape shown in the drawing includes a plate 2, on which are fixed two tubular elements 3 forming grippers. Each tubular element 3 is provided on its outer face with two grooves annular 4 offset longitudinally relative to each other.
  • This gripper is provided with a framework which extends it towards the inside of the forms, over its entire height, perpendicular to the axis longitudinal of the shape.
  • This frame includes a first profile metal 5 of T section. This metal profile comprises, on the core of the T, two sets of fingers 6 located near its ends.
  • the framework also includes a second section 7 of C section, delimiting grooves, in which the fingers 6 engage to ensure the profile 7 guide with respect to profile 5.
  • profile 7 In the grooves of profile 7 two stops 8 are provided near the upper end of the profile, in the position shown in the drawing, these stops 8 avoiding release complete of profile 7 opposite profile 5, by pressing against the fingers lower 6 of the profile 5. It appears from this structure that, if the two profiles are perfectly parallel and held against each other when the profile 7 is engaged in the profile 5, the profile 7 can pivot relative profile 5 when it is released therefrom, as shown in FIG. 5. The profile 7 can be kept in the engaged position on profile 5, by example using a ball, not shown in the drawing, pushed elastically. Profile 5 comprises, on its face opposite to profile 7, two parallel cylindrical fingers 9 each having a slot diametral 10 opening in its free end, as well as a tapped hole 12 opening into this same free end.
  • the threaded hole 12 is used for the engagement of a screw 13 allowing, according to the screwing, to adjust the section of the finger 9.
  • the two fingers 9 are used for the engagement of a part 14 forming the rear part of the form and comprising the heel thereof, this part having for this purpose two cavities 15 of shape complementary to that of the fingers 9.
  • the adjustment of the section of the fingers 9 ensures excellent friction resistance of the rear part 14 of the shape on the fingers 9.
  • the profile 7 comprises, for its part, a finger 9 of same structure as the fingers 9 described above, intended for the engagement of the front part 16 of the form. After assembly of the parts front 16 and rear 14 on the framework 5, 7, the shape has the configuration shown in Figure 2. To achieve the establishment of a rod or the removal of it, it is possible to slide the profile 7 opposite the profile 5, then rotate it to bring the toe closer to the heel, which facilitates manipulations of the rod.
  • the invention is not limited to the single form of execution of this form, described above by way of example. This is how in particular that the means for guiding the two parts of the framework, one compared to each other could be different, or that the part central frame could carry part of the shape which would then made in three pieces, without leaving the framework of the invention.
