Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mold for making it possible to manufacture footwear with five circumferences.

In the production of footwear, a wooden ``o'' is used that reproduces the characteristics of each leg, such as dimensions, whether it is left or right foot, and the type and appearance of the footwear. The torso or upper part of the footwear is placed on top of this ``mold,'' then the ``first part'' is attached by nailing, and finally all other operations are performed.

Today, all of these operations are done by hand, and the fins that attach the shoe uppers are manually transferred from one machine to another (e.g., broaching machine, milling machine, injection machine, etc.).
sewing machine...).

Automation of footwear manufacturing is nowadays increasingly required for the obvious reason of increased productivity, but the known molds are not practical as the molds are equipped with only very rudimentary gripping means. As a matter of fact, it is impossible to realize this, and the reality is that it is impossible to satisfy the accuracy requirements necessary for carrying out automatic one-shot meetings using rosettes.

In reality, the torso of the footwear is vertical to the arm of the rosette.
It is important to strictly maintain a certain predetermined position in both the horizontal and vertical directions. Conventional molds then have a stepped surface at the top, the central part of which is provided with a solid hole for mounting on the T-piece, which also serves as a base for footwear manufacturing. During certain operations, the mold and footwear are supported upside down. It will be clear that such a gripping device does not provide sufficient precision to enable rosette automation.

The object of the invention is to provide a shoe-making "mold" whose arrangement allows for working with the arm of the rosette. The mold is then fitted with a grip head on the upper part, and at least two hooks each arranged on its front and rear surfaces have a mechanism similar to said spatula, teeth or protrusions; Its shape is also characterized by a gripping mechanism with complementary shaped pawls, between which the hood can be gripped while keeping it in a strictly defined position.

Furthermore, it is advantageous for the grip-head to have a stepped surface on the side receiving a code-like or scale-like display for reading at the moment the mouthpiece grasps it.

Finally, said grip φ is further akin to teeth or protrusions, at least provided on its front surface.

It is advantageous to have one positioning mechanism and to allow the mold to rest resting in a precisely defined position on the storage shelf, with or without footwear.

A better understanding of the invention, and other features thereof, will become apparent from the following description of a preferred implementation with reference to the accompanying schematic drawings.

Referring to both FIG. 1 and FIG. 2, the mold of the present invention includes:
Reference number as a whole! Figure 7 shows the shoe inside the shoe during the manufacturing process, but then the upper part 3, that is, the area above the heel, is relatively removed as can be seen from the figure. It differs from conventional technology boards in that a large grip (spatula) 1g is attached. This head g is knee as shown in the figure, two polyhedron-shaped angular protrusions cut diagonally! ! , ? f, and are located on the rear and front surfaces of the spatula F-h tt, respectively. This allows the arms of the rosette with complementary grip pins Th to grip the mold while keeping it in a precisely defined position.

- it has a lateral stepped surface if arranged perpendicularly to the general plane of the bottom A and marked with corred graduations 7; As a result, the robot has a grip of type l.
When the head is fully grabbed, the size, shape, type, and whether the shoe is on the right or left side are read, and a program is selected and started accordingly. This ensures that each machine to which the shoe arm carries the shoe performs the correct operation on the shoe, taking into account all the characteristics of the mold involved.

In this embodiment, the scale 7 marked with a scale 7 is a scale 7 shown on the small plate 30 of the removable type in the groove 9 held on the stepped surface j in the sliding groove 31. .

The small plate J 0f-4 can of course be easily replaced.

- It is arranged under the projection t on the rear surface of the head μ and has an angular carved tooth IO lined with dovetail joints.

This allows Type I to rest supported in a precisely defined position on the storage shelf, as can be seen from Figure 3 below, with or without footwear. .

- The head 4 has a vertical rib at the lower center for mounting on the rear upper part 3 (heel area) of the lvl.

Therefore, the rear part of the upper surface of the mold is cut straight into a plane, and this plane part is provided with a stile, a vertical groove 13, which ends vertically forward at IJ/J. ,
The rib of the head μ fits tightly into this.

The front of the rib is a hem! It's starting to come into contact with.

In addition, in the upper part of the spatula rlt, perpendicular to the bottom l, a hole 31 that does not pass through is opened, so that the mold/fr
y, can also be used in conventional machines.

As can be seen from Figure 2, after the head μ is mounted on the heel area 3, it is inserted into the mold from the underside using two holes /7 with shoulders drilled into the mold l. It is fixed to the mold by a screw/A inserted into the mold.

Next, when we examine Fig. 3, the model of the present invention with the shoe attached is as follows.
Basically, it consists of a front support rod 19 with a uniform cross section and a rear rod 20 for supporting and accurately positioning the deaf head 4t.
It is supported in a precisely defined position on a storage shelf lI with f. The front lower part of the mold or sole is supported by a front bar 19 as shown in the figure, and a notch 21 is provided on the rear bar λO in a shape that fits the teeth of the lower rear part of the 6-hole. so that each angular tooth IO is tightly fitted into the corresponding notch 21.

In FIG. 3, as an example, it is assumed that mold 1 is placed on storage shelf lf by arm rosette 2 with fully or partially finished footwear.

The arm rosette 2λ is provided with a grip head 3 having a pinch 2a, one claw of the pinch! is fixed in a predetermined position on the head 23, and a spatula h" of type l is fixed in place on the head 23.
−, has a shape that closely matches the posterior protrusion r of t; on the other hand,
The other pawl 2, which is shaped exactly to match the front projection 9 of the head 1, is attached to the head 23 of the rosette as shown in the figure.
A jack is fixed on top of the core.

Due to the movement of the jack 2t and the arm leg robot here, the head μ can be grasped by the pinch 2ttB and the protrusions t and 9 in extremely accurate relative positions, and the complementary claws 2! , it will be firmly fitted into the 2t.

Lastly, the robot's grip HetsuPco 3 is the stepped surface of the type L spatula IF tt! It is equipped with a reading device F-29 for the Co-P scale shift mounted on the top.

In this embodiment, the reader performs all t approximate pickups (not shown) to detect the presence or absence of a pion in the corresponding threaded projection.

It will be clear that the invention is not limited only to the embodiments described above. Spatula) ′α has a protrusion! ,
The number 9 can also be provided with teeth in the form of a row of dovetails, for example, or conversely the tooth IQ can be replaced by a lug. These angular shaped protrusions or teeth can also be replaced with the shape of a portion of a circle. Finally, the conventional W made to match the spatula t based on the present invention.
It is also advantageous to make the combination of the body of the invention and the spatula in one piece, for example by molding a plastic material or a light alloy.
