Definitions
- the present invention refers in a rotating head for a back part molding machine for shoe uppers with an integrated system of wipers and a system of independent, divided, pincers for the lengthwise stretching of the uppers, which has been invented, designed, manufactured and applied on this type of machines for the first time and exclusively by us.
- the shoe Due to its manufacturing requirements i.e the shoe consists of one isolated seat without any side parts and a front part of some shape which is not connected with the seat, expendable stretching strips of material are introduced on the edges of the sides of the seat part, in order to enable it to be stretched and finally be formed-molded in a controlled way, while the proper angles for the seat, lasting margin and correct overall shape can be achieved only when the operator has visual contact with the back and bottom part of the seat -seat upper, the part that is folded under the finished shoe as well as the back seam.
- the purpose of the present invention is to eliminate all the drawbacks as well as the problems that arise from the use of the known shoe back part molding machines, by presenting a new technology rotating head for the forming of shoe uppers, which includes in a complete system all the necessary items for the forming of the seat of the shoe upper, except the male mould, in cooperation with a system of divided-independent pincers, where each pincer operates and is adjusted independently of the other giving thus the ability to the pincers to be a natural continue of the base shape of the male mould.
- the referred to system of rotating head has a support base for a female mould, means to compress the female mould on the male mould, a female mould, a system of pneumatically moving wipers with capability of alteration of their horizontal distance from the female mould and the mentioned wipers system is permanently positioned on a base which supports the female mould, it also has the capability to alter the wipers starting point by 100 mm.
- the whole system comprises a complete assembly which can, due to its proper attachment and its housing, be rotated by 180 degrees around its vertical axis, which passes along the mean vertical axis of the female mould.
- the new pincers can be adjusted in the sense of the width of the base of the male mould and with different distances from the vertical axis were the male mould is housed and in the sense of the asymmetrical adjustment of distance between the operator and the pincers -one pincer closer than the other where both of these adjustments can be introduced simultaneously.
- the divided independent pincers system has no stroke distance (pulling distance) stop screw, but the stroke is adjusted with a pneumatic way through the control of the output flow of the pneumatic cylinder that moves the system in the vertical axis -stretch parallel with the male mould -the operator chooses a starting pull, exactly like the present technological level and through the exhaust of a time calculated volume of air from the cylinder when the need occurs for a further pull, one just presses on a switch placed for this purpose which exhausts the extra amount of air performing a further pull from the cylinder, while the control of the initial pull occurs via a solenoid valve at the outlet of the cylinder and with a timing of the electrical signal of its solenoid.
- Drawing 2 Displays the side section view of the rotating head system with the wiper and the male mould at an open position.
- Drawing 3 Displays the front view of the system of the rotating head system with the wiper at a closed position.
- Drawing 4 Displays the side section view of the rotating head system with the wiper and the male mould at a closed position.
- Drawing 5 Displays the top view of the housing point of the rotating head system, in a front position of the wipers.
- Drawing 6 Displays the top view of the housing point of the rotating head system, in a back position of the wipers.
- Drawing 7 Displays the pincers at a side view.
- Drawing 8 Displays the pincers at a front view.
- Drawing 9 Displays the pincers at a top view.
- the rotating shoe back part molding machine head with integrated wiper system consists of a supporting and rotating base with integrated wipers (1), a main head body (2), a plate for the alteration of the staring point of the wipers (3), a housing plate that supports the pneumatic cylinder for the movement of the wipers (4), a housing plate to support the wipers system on the body of the head (5) a quick exhaust valve (6), a housing and air tightening of the pressure mean of the female mould to the male mould (7) a right wiper carrier with slots (8) a wiper for the flanging of the material of the shoe upper (9) a female mould for the forming of the shoe upper (10) a wiper for the flanging of the material of the shoe upper (11) a left wiper carrier with slots (12) a mean of pressure creation of the female mould on the male mould (13), a screw for wiper holding (14) a screw for wiper holding (15) lower ball bearings with a screw and a nut for their housing (16) upper
- the whole system presents a complete assembly which due to its housing and fixing mechanism can rotate around its vertical axis, which passes in the sense of the mean vertical axis of the female mould (10), with this rotation and with the rotation of the male mould (38) the same machine is converted and can process moccasin . . + . + . . ., , shoe uppers and mim counters, m a very short time, smce the operator can nave visual contact with the wipers (9) (11) as well as with the back and under part of the shoe upper (37) and when rotated to the normal front position it can process normal shoe uppers, while with the known today technological level two different machines would be required dedicated to each type of work.
- the system of independent divided pincers consists of a pneumatic cylinder base (42) an pincer alignment guide (43) and arc shaped base for the support of the pincers assembly (44) a plate for the housing-fixing of the pincers system (45), a pneumatic cylinder for the pulling (46), a screw for the fixing of the pneumatic cylinder shaft (47) a pneumatic cylinder shaft (48) a jaw (49) a jaw protection pad (50) a screw for the cover fixing (51) a base for the jaws fixing (52) a housing for the jaws base (53) a jaw movement pneumatic cylinder (54) an elesa screw for the adjustment of the inclination of the base of the pincers ( 58) a guide screw (59) a connecting plate for the adjustment of the base of the pincers (60), an articulation pin for the jaw (61) and an articulation pin for the pneumatic cylinder (62).
- the jaw (49) With the activation of the two cylinders (54) through the shaft (48) the jaw (49) is pushed so as to come in contact with the upper material (37) and to hold it at the relevant place and then the pneumatic cylinder for the stretching is activated (46) in order to stretch the shoe upper, while through the back up stop screw (57) one can adjust the pulling distance and trough the screws (58) the inclination of the complete system of the pincers so as to adapt and process any type of last.
- the pincers can be adjusted simultaneously and in the sense of the width of the base of the male mould and with different distances from the vertical axis of its housing, but also in the sense of the asymmetrical adjustment of the distance between the operator and each individual pincer, one outer of the other, and since there is no conventional stop screw for the adjustment, the stroke of the system is controlled with pneumatic means by the control of the exhaust flow of the vertical movement pneumatic cylinder - pulling in a parallel sense with the male mould ,in this way the operator chooses an initial pull, exactly like the present technological level and through the exhaust of a time calculated volume of air from the cylinder when the need occurs for a further pull, one just presses on a switch placed for this purpose which exhausts the extra amount of air performing a further pull from the cylinder, while the control of the initial pull occurs via a solenoid valve at the outlet of the cylinder and with a timing of the electrical signal of its solenoid.
