Definitions

  • This invention relates to footwear making plants, and more particularly, concerns a system for mass processing semimanufactured articles, specifically for edge "carding" uppers and coating them with an adhesive preparatory to adhering a sole member thereto.
  • An industry-level footwear making cycle involves sequential operations to be performed on one and the same region of a semimanufactured article and each requiring approximately the same machine time.
  • Two operations of this kind are the "carding" of the uppers edge, as folded over and glued onto an inner supporting sole known as the insole, and the application of an adhesive over the carded region for subsequent attachment of an outer sole member thereto.
  • a process step whereby the leather surface of the uppers is roughened preparatory to gluing is commonly referred to as "carding".
  • a semimanufactured article is taken under a carding machine and processed by driving a carding tool across the folded over and glued edge of the uppers, all around the footwear peripheral contour.
  • the operation can be automated using program equipment including, for instance, template and feeler means, whereby the carding tool can be made to travel a definite processing path.
  • the semimanufactured article while still held in its fixture, is brought under an adhesive applicator machine having a moving injector operated to travel substantially the same path as the carding tool and to coat the surface to be glued with an adhesive layer.
  • the carding step is usually preceded by a preparatory or pre-carding step, to remove residual matter from the previous step (gluing of the uppers to the insole), and the adhesive application is preceded by a brushing step to remove dust and particulate left over from the carding step.
  • a preparatory or pre-carding step to remove residual matter from the previous step (gluing of the uppers to the insole)
  • the adhesive application is preceded by a brushing step to remove dust and particulate left over from the carding step.
  • Figure 1 shows schematically a shuttle-type of workpiece holder 5, shuttle track means defining two travel paths for the shuttle holder, and processing stations where the semimanufactured articles carried on the shuttle holder are variously processed or treated.
  • the largest number of said shuttle holders that can fit in the path at any one time will depend essentially on the processing time allowances at the individual stations. In actual practice, it would be selected to minimize downtime between process steps at one and the same station.
  • the shuttle track means comprise in this embodiment three parallel rails 10, 11, 12, and two parallel translation members 13 and 14 laid in the form of two juxtaposed letters "U" with the legs of the U's defining junction rails.
  • Each of these translation members can be moved in a crosswise direction to the parallel rails, such that the two legs of each "U", when in one position, merge with the center rail 11 and one of the side rails, and in another position, merge with the center rail 11 and the other of the side rails.
  • a shuttle holder 5 as shown in Figure 2, consists of a car 16 having a mounting block 17 and a former holding post 18.
  • the former has a semimanufatured article fitted thereon which consists of an uppers 19 and an insole 20.
  • the post 18 is adjustable in height to enable the shuttle holder to accommodate a range of semimanufactured articles and formers.
  • a suitable locking means of a conventional kind such as a clevis, not shown, is arranged to retain the toe and heel ends of a shoe fixedly in place.
  • the shuttle holder is held up for switching either to the rail 10 of the carding leg or the rail 12 of the adhesive application leg; B: pre-carding; C: carding; Y: in this position, i.e. with the translation member 14 leg aligned to the rail of the carding leg 10, the shuttle holder is held up for switching to the center rail 11; Z: to this position, i.e. with the translation member 13 leg aligned to rail 12, the shuttle holder is brought after moving over rail 11 from position W, via the translation member 13; D: brushing; E: adhesive application.
  • the shuttle holder movements along the path, the residence times of the shuttle holders at the various processing stations and the other positions, and the translation member movements are controlled and coordinated by a central control unit in accordance with a program stored in the unit and positional information from the individual shuttle holders and other signals, among which are control signals entered by the operator.
  • the main operational connections between the central unit UC, the shuttle holders 5, the locking A and processing B, C, D and E stations, and the parallel translation members 13 and 14 are shown diagramatically in Figure 3.
  • the central unit UC receives positional signals from the position detectors P associated with the shuttle holders and sends control signals to the drive motors M for driving the shuttle holders and to processing stations B, C, D and E, to thereby start, stop and select the processing procedures. Further signals can be received by unit UC from travel limit switches and other consent means associated with the machines in the system, and from on/off switches, generally shown at S, controlled by the operator.
  • the program functions performed by the central unit are as follows (although not necessarily in the order shown): monitoring the state of the consent means; timing the processing step durations; computing the shift paths between processing stations; timing the shuttle holder movement durations; transmitting actuating signals to each of the shuttle holders for their respective shift movements; detecting the shuttle holder positions; sending timing signals to each shuttle holder; sending actuation signals to the parallel translation members; detecting the states of the consent switches under control by the operator.
  • the operator unloads a processed workpiece from, and loads one to be processed onto, a shuttle holder located at position X (2s); the translation member 14 occupies the position shown in full lines in Figure 1 (on the left looking at the drawing); the shuttle holder moves to station A where the workpiece is locked to the former (3s); the shuttle holder reaches position W (3s) on the translation member 13 that locates as shown in full lines in Figure 1 (right-hand position); the translation member 13 moves into the position shown in dash lines in Figure 1 (left-hand position) (1s); the shuttle member reaches station B where it is pre-carded (3s); after a pause (2s), the shuttle holder moves to station C where it is carded (4s), and then into position Y (1s) while the translation member 14 occupies the left-hand position; the translation member 14 is moved into the right-hand position (1s) where the workpiece can be inspected by the operator; the shuttle holder moves once again through the locking station A (3s) and reaches position W (3s) with the translation member
  • the overall duration time of a complete processing cycle is approximately 38s.
  • the parallel translation members 13 and 14 will stay in the left-hand position for about 7s and in the right-hand position for about 5s. They will both locate simultaneously on the same side for about one half their respective residence time in either position.
  • a machine may be advantageously used whose tooling can admit of a setting with 4 degrees of freedom.
  • the carding head shown at 21 in the drawing, can move along a horizontal axis y, a vertical axis z, a vertical setting axis j, and a horizontal setting axis w.
  • the relative movement of the tool bit and the workpiece along the x direction is accomplished by holding the tool bit stationary and reciprocating the shuttle holder along the rail to have either sides of the workpiece processed.
  • the system just described operates in a fully automated manner, while still allowing the operator to intervene before the major process steps; and this can take place without discontinuing the processing cycle, and therefore, at a high rate of system throughput.
  • the track rails for the shuttle holders could be other than straight or parallel to one another, and be a larger number than three;
  • the translation members could comprise single, rather than double, U-shaped members; and the process steps to be carried out on the system could be other than those described hereinabove.
