Abstract

Forming machine (1) for forming soles and insoles for footwear including a base (2) which supports: at least one storage container (3) for said unformed insoles; handling means (19) to retrieve said insoles (15) from said storage container (3) and position them between the forming means (4); forming means (4) including a die (6) and a punch (7) facing each other; pressing means (5) suited to reciprocally force said die (6) and said punch (7) against each other along a thrust axis (X-X), to produce the forming of said insoles. At least one of said die (6) and punch (7) is linked to a rocking bolster plate (14) pivoted to said pressing means (5), suited to set said die (6) or punch (7) at an angle to said thrust axis (X-X) allowing the progressive closure of said die and punch during the rotation of said plate (14) around said pivot and the release of said insole by said handling means (19). <IMAGE>

Description

DESCRIZIONE DESCRIPTION

Secondo il trovato si viene a realizzare una macchina garbatrice con la quale si esegue la curvatura e la sagomatura delle suolette ‘<“>sotto piede” nell’industria calzaturiera. -La macchina è essenzialmente costituita da una grossa pressa che agisce sul piano orizzontale e comprime con una lbrza di circa 30 tonnellate due stampi, maschio e femmina, fra i quali viene automaticamente posizionata la suoleta da sagomare.-Carateristica principale della macchina garbatrice ideata è il fatto che la suoleta viene compressa gradualmente, dato che lo stampo maschio esercita la compressione sulla femmina mediante un contato volvente, iniziando ad esempio dalla zona del tallone della suoletta per terminare in corrispondenza della punta.-Nelle due tavole di disegni unite, la fig.l mostra dall<’>alto la macchina ideata; la fig.2 è una sezione verticale della stessa; la Fig.3 rappresenta di fianco la macchina, provvista di un alimentatore automatico delle suolette.-NEL, DETTAGLIO.- Come mostra la fig.l, la macchina comprende un banco fisso _1, portante quatro colonne cilindriche metalliche 2 sulle quali può scorrere lo spallamento trasversale 3, spinto dallla testa 4 di un pistone oleod inamico. -La traversa scorrevole 3 porta, fulcrata sulla stessa, una leva oscillante 5 la cui estremità libera è sostenuta e spinta dalla molla 6.-la leva 5 è solidale con lo stampo maschio 7 e, in fase di riposo si mantiene inclinata come in fig.1. According to the invention, a molding machine is created with which the bending and shaping of the '<"> underfoot" insoles in the footwear industry is carried out. -The machine is essentially made up of a large press which acts on the horizontal plane and compresses two molds, male and female, between which the sole to be shaped is automatically positioned. the fact that the sole is gradually compressed, since the male mold exerts the compression on the female by means of a rolling contact, starting for example from the heel area of the sole and ending at the toe. .l shows the machine conceived from above; Fig. 2 is a vertical section thereof; Fig. 3 shows the side of the machine, equipped with an automatic feeder of the soles. - IN, DETAIL - As shown in fig. transverse shoulder 3, pushed by the head 4 of an oleod inamic piston. -The sliding crosspiece 3 carries, pivoted on it, an oscillating lever 5 whose free end is supported and pushed by the spring 6. -The lever 5 is integral with the male mold 7 and, in the rest phase, remains inclined as in fig. .1.

Lo stampo femmina 8 è ancorato alla testata 1 del banco fisso e, quando viene interposta la suoletta ira i due stampi, inizia l’avvicinamento dello stampo maschio che comincia a toccare la suoletta in corrispondenza del tallone. -La leva oscillante 5 si inclina per la preesenza della molla 6 e lo stampo completa il contatto volvente con la suoletta che così si deforma gradualmente prima di subire la elevata compressione finale ad opera del pistone oleodinamico che provoca la stabile sagomatura della stessa. -Un alimentatore automatico di suolette 9. comprende una ventosa 10 che preleva una ad una le suolette e le sposta di quanto occorre perchè una pinza 11 le possa prendere e portare nella giusta posizione fra gli stampi 7 ed 8 -Data la disposizione degli stessi, appena inizia il contatto, la suoletta rimane in posizione e la pinza può abbandonare la presa per tornare airalimentatore a prendere la successiva, e così via.-l a macchina può essere attrezzata con una moltitudine di coppie di stampi, in base alle diverse dimensioni e ai diversi tipi di scarpe da produrre, siano esse da uomo, donna o bambino.-Per migliorare ancor più la graduale deformazione della suoletta si prevede di realizzare l accoppiamento dei due stampi anche secondo una esecuzione del tipo "a forbice’<’>, rendendo cioè oscillante anche il supporto dello stampo femmina. -Da quanto esposto ed illustrato, risultano evidenti la novità e roriginalità della macchina garbatrice ideata la quale, nella fase esecutiva potrà comportare le necessarie modifiche ai suoi particolari costruttivi, senza peraltro uscire dai concetti inventivi ampiamente esposti.-Ogni variante esecutiva rientrerà nell’ambito della presente invenzione. The female mold 8 is anchored to the head 1 of the fixed bench and, when the insole is interposed between the two molds, the male mold approaches, which begins to touch the insole at the heel. -The oscillating lever 5 tilts due to the presence of the spring 6 and the mold completes the rolling contact with the insole which thus gradually deforms before undergoing the high final compression by the hydraulic piston which causes the stable shaping of the same. -An automatic feeder of insoles 9. comprises a suction cup 10 which picks up the insoles one by one and moves them as necessary so that a gripper 11 can take them and bring them into the right position between the molds 7 and 8 -Given the arrangement of the same, as soon as contact begins, the insole remains in position and the gripper can leave its grip to return to the feeder to take the next one, and so on. different types of shoes to be produced, be they for men, women or children. that is, the support of the female mold also oscillates. bring the necessary changes to its construction details, without however departing from the inventive concepts widely exposed. - Each executive variant will fall within the scope of the present invention.

Claims

CLAIMS 1) "GARBATRICE MACHINE FOR BENDING AND SHAPING THE INSOLES UNDER FOOT OF SHOES FOR MEN, WOMEN AND CHILDREN, IN THE FOOTWEAR INDUSTRY", characterized by the fact that it consists of a large press formed by a fixed bench, which acts on] the horizontal and compresses two molds, male and female, between which the insole is automatically positioned under the foot to be shaped. -2) "GARBATRICE MACHINE. . . as in Claim 1), characterized by the fact that the insole being worked is gradually compressed by the male mold which exerts the initial compression on the female by means of a rolling contact which starts for example from the heel area and ends at the toe. -3) - “GARBATRICE MACHINE. . . as in Rev. 2), characterized by the fact that the initial and gradual compression of the insole occurs by means of an oscillating lever carrying the male mold, pivoted on one side to the swift side of the press and with the free end supported and pushed by an adequate spring.- ' 4) - “GARBATRICE MACHINE. . . as in Claims 2) and 3), characterized by the fact that the gradual deformation of the insole can be obtained with both molds carried by two oscillating levers, according to a "scissor <"> type execution. -5- “GARBATRICE MACHINE. as in the preceding claims, characterized in that the automatic feeding of the insoles takes place through a distributor from which the soles are taken one by one from a suction cup and brought between the shaping molds by a to and fro gripper.
