Description
- The present invention concerns a mamchine with various operative functions for the processing of shoes.
- More in particular, the present invention concerns a machine for the processing of shoes comprising various work stations supported by the same structure, each capable of carrying out, semi-automatically or automatically, a specific operation of production of the shoes, like precarding, felling, straightening, glueing in sequential phases and/or in different versions.
- There are many shoe processing machines; among them those at present most widely diffused carry out, according to single phases, or in sequential coupling on assembly lines, single operations in semi-automatic or automatic fashion. Said machines, while very efficient and valid from the point of view of the quality of the end product, and that of productivity, have so far been designed for installation on single stations arranged in sequence or in highly automized assembly lines.
- Consequently, said single, independent machines and said assembly lines are unsuitable in particular conditions, e.g. in production cycles with special series of shoes, or in the production of series of shoes with high varieties of models and/or sizes, as they lead to unfunctional, expensive organizing and productive solutions.
- The object of the present patent is to solve the above pro blems.
- According to the present invention, this object is obtained by means of a machine with various operative functions for the processing of shoes, comprising:
- a supporting structure with a front part;
- a first operating head for the removal of tufts, precarding and preparation of the shoes;
- a column, movable vertically and horizontally, to move away from or approach the operating head, equipped with centering and supporting means of the shoes;
- a second operating head for the felling and straightening of the heel of the shoes, movable along a circular trajectory with the center at the heel;
a a heating plate coaxial to the column, mounted on said operating head above said column;
- a third operating head for straightening, felling, glueing and carding;
- means to move said third on a vertical plane backwards and forwards with respect to the longitudinal axis of the shoe;
- means to move third head on a vertical plane away from or towards the surface of the plant of the shoe; and
- means to move said third head on a horizontal plane to the right or left of the fixed position of the shoe. - In the machine of the present invention, various motorized operating heads, each suitable to carry out a specific function, are grouped in a same structure.
- Said machine is therefore substantially compact and with limited dimensions and is capable of carrying out automatically the most important operations of preparation of the shoes.
- The advantages essentially consist in the fact that the machine, in its compactness and limited dimensions and in its versions, is capable of carrying out in sequence the precarding, felling, straightening, carding and glueing operations. Another advantage consists in the fact that the machine, even in its plurality of functions and of mechanical positioning, fixing, moving and centering members, does not require the presence of any operators except for the precarding, loading and discharge phases.
- Furthermore, its compact, functional structure permits its installation in any type of room, even of modest dimensions, solving, in particular, also the operative applications of the socalled "island" type.
- The present invention can be better understood from the following detailed description in which reference is made to the figures of the enclosed drawings which represent some preferred but unbinding constructive forms, and in which:
- fig. 1 shows the shcematic view of the cross-section of the machine of the present invention in the carding version;
- fig. 2 shows the schematic view of the longitudianl section of the machine of figure 1, in felling+straightening version;
- fig. 3 shows the schematic view in plan of the machine of the previous figures in carding version;
- fig. 4 shows the schematic view of the longitudinal section of the machine in the previous figures, in carding version;
- fig. 5 shows the schematic view in plan of some processing phases with the respective positionings and displacements of the operating carding heads;
- fig. 6 shows the lateral schematic view of a carding roller of barrel shape with knurl with double opposite screw;
- fig. 7 shows the schematic view of the cross-section of a felling roller;
- figs. 8 and 9 show respectively the front and lateral schematic view of the centering and fixing device of the point of the shoe; and
- fig. 10 shows the schematic view of the cross-section of the control device of the felling roller of the heel of the machine of the present invention in felling and straightening version.
- The figures illustrate a machine with various operative functions for the processing of shoes substantially composed of a structure 1 on which the heads of a plurality of work stations are installed. The
first operating head 2 comprises anabrasive belt 3 stretched between alower idle pulley 4 and anupper pulley 5 moved by amotor 6. Theidle pulley 4 is equipped with a stretching means 7 of known type. Below theidle pulley 4 is present aconveyor 8 connected to a motorizedexhaust fan 9. - At the height of the
conveyor 8, the structure 1 presents an opening from which projects thehead 53 of apercussion device 54, preferably of pneumatic type, which can be used by the operator for any finishing hammerings. - The
percussion device 54 is positioned inside the structure 1. - The motorized
abrasive belt 3 is substantially positioned at the exterior of the structure 1 , at its front part (19), at height of man, and can easily be used by the operator for the necessary preliminary operations of removal of the tufts in front and behind, of precarding and at any rate of preparation of theshoes 10, before these are positioned and fixed on a supportingcolumn 11. - Said
column 11 comprises some centering and fixing members of the toes of theshoes 10 comprising apiston 13 equipped at the upper free end with supportingplugs 14 and apiston 15 connected to two centeringjaws 16, as illustrated in figures 5, 8 and 9. - The
plugs 14 comprise also elastic means 17 elastically supporting aroller 14′ which accompanies and guides especially the short shoes in the approach phase to said plugs. Said elastic means 17 facilitate and guarantee the adherence of the plugs to the toes of the shoes, regardless of their shape or size. - The centering
jaws 16 are connected to therespective control piston 15 by a series of levers arranged withparallelogram 18 which permit the opening and closing movements round the toes of the shoes, according to the return and outward stroke of said piston. - The
column 11 is supported at the base to thefulcrum 20, and, to facilitate the loading and discharge operations of the shoes, said column may take up theinclined position 11′ towards thefront part 19 of the machine, rotating round itsfulcrum 20, under the action of a lateral piston 21 (see fig. 1). - In the
abovementioned front zone 19 opens a protectedwindow 50 which gives access to the interior of the structure 1. The operator positioned in thiszone 19, after having carried out the specific operations with theabrasive belt 3 of theoperating head 2, places theshoe 10, with the relative last, on the connecting pin of thecolumn 11 ininclined position 11′, then the column returns to vertical position. Subsequently, theshoe 10 is centered and supported by the abovementioned centering and supportingmembers - The
column 11 is fixed in the lower part to a pneumatic or hydraulic oroleodynamic piston 11˝ with vertical axis. Aheating plate 51 is fixed to the second operatinghead 22, above and coaxially to thecolumn 11. - In a first version, when the machine operates as felling and straightening machine, the
column 11 is thrust vertically upwards by thelower piston 11˝ until it brings the heel zone of theupturned shoe 10 into contact with a heat-plate 51. - The force of contact between
plate 51 andshoe 10 is adjustable according to the product to be treated and to the squashing and straightening needs of said heel zone. - The machine in the felling and straightening version comprises a second operating
head 22 composed of a percussion unit 25 (see fig. 10), preferably but unbindingly of pneumatic type,equipped with fellingroller 26, shaped to adhere and beat uniformly and regularly along the crown of the heel of theshoes 10. - The
operating head 22 is fixed, in position substantially oriented in horizontal direction, to acarriage 52 which can make ahorizontal arc movement 27, whose center corresponds to theposition 28 taken up by the heel of theshoe 10. Thecenter 28 is therefore aligned with the vertical axis of thecolumn 11. - During the movement of circular traverse round the
arc 27 of thecarriage 52, theshaped roller 26, of substantially conical conformation, presses and strikes the leather of the heel of the shoe along the crown of the heel to make it perfectly adherent to the last. - The driving
head 22 rotates in synchronism with the third operatinghead 29. It comprises (see figs. 2 and 3) amotor 30 supporting therollers 31, mounted on anadjustable support 32 applied to acrosspiece 33. Said crosspiece is, in turn, mounted in swinging manner round afulcrum 34 positioned at the upper end of avertical support 35 fixed at the base to thepin 36 and swinging round saidfulcrum 36, by means of the action of a reartransversal piston 37. - The vertical oscillation of the
vertical support 35 is oriented with respect to the longitudinal axis of theshoe 10; it therefore permits a forward and backward travel from same. The swinging vertical movement of the crosspiece round thefulcrum 34 is produced by arear piston 38 and permits lower- or lifting of themotor 30, bringing theroller 31 towards or away from the surface of the plant of theshoe 10. Theadjustable support 32, finally, is driven by alateral piston 39 and makes it possible to rotate themotor 30, withrelative roller 31, in a horizontal plane, to the right or left of the fixed position of the shoe in processing. - Through said movements: vertical forward or backward produced by the rear
transversal piston 37; vertical upwards or downwards produced by therear piston 38, and horizontal to the right or left produced by thelateral piston 39, it is possible to carry out the necessary processings of felling and straightening, on the entire lower surface of theshoes 10 in processing, regardless of their last; for men, for women, conformed for applications of low or high heels, for children, and of their size. In particular, to the oscillation to the right and left of themotor 30, and therefore of theroller 31, permits the perfect processing of straightening of the two lateral edges of the shoes, both during the outward and return stroke of thevertical support 35. The amplitudes of the various strokes of oscillation are regulated bylimit switches 80 whose micrometric regulation of the amplitude of displacement is obtained by means of a motor reducer 81 through a right-left threadedbar 82. - In the carding version, the
drive head 22 may be exchanged with adrive head 22′ comprising amotor 23 supporting acarding roller 24 and fixed to the abovementioned movable carriage (52). - Said carding roller (24) operates on a horizontal plane corresponding to that of the heel of the shoes (10).
- In this case, the
column 11 comprises a piston device (12) of known type, suitable to fix the last of theshoe 10, while the same centering and fixingmembers third operating head 29 withmotor 30 is used in the carding version, using in this casesuitable carding rollers 31′. The felling, straightening and carding operations are carried out using, respectively,rollers 31′ and 31˝ with different characteristics. - In particular, besides the rollers of traditional type known for straightening and carding, with concave surfaces towards the center and with opposite spirals of rigid type and of soft type with inserts of metal bristles,
rollers 31′ and 31˝ with some particularities which improve their performances are used. - The straightening
felling rollers 31′ are preferably barrel-shaped and present the surface furrowed by opposite double smooth screws, which, however, do not develop long spirals of circumferential development, but long polygonal developments. In substance, the peripheral surface of therollers 31′ presents a quantity of flat smoothtransversal strips 41, alternated to curved smooth strips 42. - The quantity of said flat strips may vary according to straightening needs. During rotation of the
roller 31′, produced by themotor 30, thecurved surfaces 42 andflat surfaces 41 alternate in the pressure-contact on the surface of theshoes 10 and their difference causes a striking action which carries out a perfect action of straightening. - Similar
flat surfaces 41 are obtainable also on therollers 31˝ with concave conformation towards the center and at any rate on any other type of roller, possibly cylindrical, conical or similar. - The carding
rollers 31˝′, also substantially and preferably present a barrel shape, with surface covered by doubleopposite screws 43, knurled, inserted with double opposite smooth screws 40. Similarly, the same double spiral conformation may be used also on cardingrollers 31˝′ with concave surfaces towards the center. At any rate, for the carding of the shoes which can be carried out with the operatinghead 29, traditional rollers with abrasive or cutting surfaces can also be used. The same abovementioned characteristics, present on the rollers of themotor 30 are also present on therollers 24 of themotor 23, for rear rotating carding. - For any glueing phase it is sufficient to substitute the straightening
roller 31′ or cardingroller 31˝ with a special glueing roller, of traditional type, equipped with a glue tray. A cleaning/suction device 83, comprising an idlerotating brush 84, is fixed on thesupport 32 and has the function of cleaning periodically both the fellingroller 31′ and the cardingroller 31˝. The forward and backward movement of thebrush 84 from theroller 31′ or 31˝ to be cleaned, is carried out by apiston 85, which acts on saiddevice 83, making it rotate round the fulcrum.
