BEST MOPES OF CARRYING OUT THE INVENTION
With reference to the figures, reference numeral 1 generally designates a stepwise operated carrousel supported by a vertical shaft 2.
This carrousel carries a plurality of magazines, e.g. four indicated with Cl, C2, C3, C4. The magazines are arranged in quadrature and symmetrical with respect to vertical diametrical planes of the carrousel, for instance the planes Dl and D2 shown in figure 3.
It is understood that the number of magazines can vary; there can be e.g. two, three, five six, etc. magazines. The magazine Cl, and likewise all the other ones, includes : two stationary vertical stems 3, symmetrical with respect to a relative diametrical plane Dl of the ones mentioned above;
- a first pair of movable vertical stems 4, symmetrical with respect to this plane Dl, freely introduced into the relative slots 5 made in the carrousel parallel to this plane, and with the jackets 4a fastened to a first crosspiece 6 made in the region of the lower surface la of the carrousel;
- a second pair of movable vertical stems 7, symmetrical with respect to the plane Dl, freely introduced into the relative slots 5 and whose jackets 7a are fastened to a second crosspiece 8 made in the region of the lower surface la of the carrousel 1.
As already mentioned, the other magazines C2,C3 and C4 are made exactly in the same way as Cl .
These crosspieces 6, 8 are carried by two cylindrical rods 9 and can slide with respect to these rods independently from each other.
The cylindrical rods 9 are fastened to a bar 10 symmetrically with respect to the above-mentioned diametrical plane. The bar 10 is attached to the lower surface la of the carrousel 1.
A head 11a of a bolt 11, engaging with the second crosspiece 8, goes in abutment against the edge 12a of a groove 12 made in the carrousel along the diametrical plane already mentioned. Acting on the bolt 11, the position of the crosspieces 6, 8 is fixed, and consequently, the mutual positioning of the stems 4, 7 is defined.
By screwing this bolt 11, the second crosspiece 8 is pressed against the lower surface la of the carrousel thus bending the rods 9 and fastening the first crosspiece 6 to the lower surface la.
The unscrewing of the bolt 11 permits crosspieces 6, 8 sliding movement with respect to the relative rods, so as to define a new spatial configuration of the group constituted by the stationary stem 3 and movable stems 4, 7.
The slots 5 do not obstruct the movement of the movable stems during the adjustment of this spatial configuration.
The stationary stems 3 and movable stems 4, 7 define the walls of the magazine C, which receives a stack of toes P.
In its lower part, the carrousel 1 carries vertical position identification metal blocks Rl, R2 , R3, R4, placed at different levels, so as to make them each of them correspond to one of the magazines Cl, C2, C3, C4; these metal blocks Rl, R2, R3, R4 are detected by a series of corresponding sensors SI, S2, S3, S4 situated upstream of a first station 50, in which the under-toes are picked up from a relative magazine (Figure 8) .
The carrousel 1 moves stepwise in direction N, in the described case, by 90° steps.
Therefore, it is possible to place any of the magazines in the station 50, which is extremely advantageous because makes it possible to store in the magazines under-toes of different sizes, for different types of shoes .
A slide 30, situated over the carrousel 1, supports in its lower part a pick up device 31, driven to move vertically by a suitable actuator 32 controlled by an electronic control unit, not shown.
The slide 30 moves longitudinally along the diametrical plane Dl of the station 50 between two extreme positions HI, H2, first and second, respectively. In the first position HI, the pick up device 31 is situated over the first pick up station 50, while in the second position H2, this device is situated over a second working station 60, in which the under-toe P is applied to an upper T. The pick up device 31 features, made in its surface 36, several holes 35 (Figure 9) , which can be connected to a source of vacuum (not shown), and heating means (e.g. electric resistor) controlled via a thermostatic device to maintain this surface 36 with the holes at a predetermined temperature.
The second working station 60 has a support surface 61 with a locking element 62 driven to move vertically by a relative actuator 63 between a working lowered position 0 (Figures 1, 2) and a working raised position (not shown). Operation of the machine becomes evident from the following description.
One of the magazines C, storing under-toes corresponding to the upper T, is moved to the pick up station 50.
The part of the upper on which the under-toe is to be applied, is placed on the surface 61 and the locking element 62 clamps the fore edge of the under-toe to the surface 61.
In time relation with the above operations, the pick up device 31, already placed in the pick up station 50, lowers until it strikes the stems 4,7, which are pushed downward against the elastic reaction of elastic means 73, connected to these stems, until the pick up device goes in abutment against the uppermost under-toe P of the stack of under-toes stored in the magazine C situated below (Figure 1) .
The pick up device 31 can pick up the under-toe P due to the holes 35 being connected to the vacuum source.
Then, the pick up device 31 is raised, so as to be locate, by motion of the slide 30, over the second working station 60.
During the pick up device 31 upward movement, the adhesive applied to the lower surface of the under-toe is activated due to the heat that the surface 36 transmits to the under-toe (Figure 2) . Lowering of the device 31 allows application of the under-toe with the adhesive already activated; this application is optimized by the pressure of the device 31 on the under-toe .
The pressure is maintained for a predetermined period of time, which is considerably shorter than time needed for the solutions described in the prior art. This is because, according to the present invention, the adhesive is already active at the moment in which the under-toe touches the upper. After the pressure period has finished, the device 31 is raised and the slide 30 goes back to the first working position HI.
This makes it possible to apply adhesive to the other surface of the under-toe, so that a suitable lining can be put thereon.
The adhesive is applied to the under-toe by a spray gun 70, operated either by an operator, or automatically by means 80 controlled by the control unit and moving along axes X, Y in relation to the under-toe size.
Consequently, the proposed machine activates the adhesive on the run, while the under-toe is transferred from the magazine to the second working station 60, which reduces the time necessary to apply the under-toe to the upper. The under-toe is positioned on the upper automatically, which, on the one hand, reduces the time necessary for performing the above described working steps, and on the other hand, optimizes the positioning, which does not depend on the operator's ability. It is also to be pointed out that the proposed machine allows to use a vast range of under-toes, four of which (in the present case) always available.
In order to use under-toes different form the ones in the magazine, it is necessary to act on the magazines, i.e. on the stems 4, 7, whose mutual distance and distance from the stationary stems 3 define the type of under-toe to be stored in the magazine.
In the present case, the magazines are situated on the carrousel 1, however they can be arranged in a different way, e.g. aligned in one or more lines, or in a still different way. Figure 10 shows an interesting embodiment of the proposed machine .
As seen m this Figure, a heat source 150 is situated between the pick up station 50 and under-toe application station 60, for sending heat (e.g hot air, infrareα rays, etc.) upwards.
This heat source 150 makes the machine extremely versatile, as far as the technical-functional aspects of the adhesive activation are concerned. For instance, the adhesive can be activated solely by this heat source; in this case, the pick up device 31 has only the task of picking up the under-toe and transferring it to the application station 60.
The adhesive is activated preferably by stopping the pick up device 31 over the heat source 150 (position F) for a period of time necessary to activate the adhesive.
This operation can be optimized and shortened by lowering the pick up device 31 by the actuator 32.
The adhesive can be activated also on the run, by the heat source 150, i.e. without stopping the pick up device 31.
The heat necessary to activate the adhesive can be supplied either by the pick up device 31 or by the heat source 150. As far as the heat source 150 is concerned, reference is made to the above described situation.
All these consideration allow for the best dimensioning of the electric resistors and of the heat source 150.
It is necessary to point out that the proposed machine can be also used for only transferring a under-toe from - l i ¬
the pick up station 50 to the application station 60, without adhesive activation (by deactivating the heat source 150 and heating means of the pick up device 31); in this case, it is obvious that the adhesive is activated in the application station 60 according to known techniques.
