Abstract:
PURPOSE: A method for setting up figures of shoes and operations of elements, managing work sequences, and performing a heel side lasting process by using a heel side lasting system having GUI(Graphic User Interface) is provided to enhance the reliability and reduce a labor cost by a computer for executing the GUI instead of an existing heel side raster controller using a microprocessor. CONSTITUTION: A figure setup page is displayed on a display window to display figures of shoes as linear vector figures which are formed by a CAD(Computer Aided Design) tool(S101). A scaling process is performed to increase or reduce sizes of the displayed figures(S102-S107). A selected shifting point of the displayed figures of the display window is shifted(S108-S111). The displayed figures are stored in a database and the figure setup page is closed(S112).
Abstract:
PURPOSE: A linear actuator is provided to install an inner ball circulating ball screw having an excellent transfer ratio in proportion to an entire size and having several microns of position accuracy. CONSTITUTION: A driving motor(200) connects to a motor driving power and the connect line of a sensor for measuring the rotation of the driving motor. Then the rotary axis of the driving motor is rotated in a limited RPM and a limited rotation angle. Using the connecting line, the rotation of the rotary axis is controlled and Thus, a ball circulating unit(10), a ball circulating tube(20) and a combining nut connected to the rotary axis are rotated at the same time. Balls(30) are continuously rolled through an inner return pass in proportion to the rotation of the rotary axis. Due to the rolling of the balls, a housing(40) generates thrust to be pushed by a holder(210). The pushed housing is recti-linearly moved by linear guides.

PURPOSE: A heel/side lasting system having a graphic user interface is provided to set up easily an operating sequence by using the graphic user interface. CONSTITUTION: A heel/side lasting system includes a Heel/Side laster(101), an industrial computer(102), an exclusive board(103) of the Heel/Side laster(101), and a database(104). The Heel/Side laster(101) is used for cementing an adhesive on a heel portion and a side portion of a shoe and adhering leather thereon. A communication port is installed at the industrial computer(102) in order to be connected with the exclusive board(103). Operating elements of the Heel/Side laster(101) are formed with a shoe bottom arrangement portion including toe carriage and toe lift, a bottom fixing portion, a pincer, an unloader, a jack post, a wiper, a tacker, a clamp, an adhesive injection nozzle, a finger, and a side pad band. A graphic user interface(105) is used for correcting or forming an operation control value and a shoe figure of style data stored in the database(104).
Abstract:
PURPOSE: Provided is an ideal path for applying paste at the bottom of shoes which utilizes generation algorithm for the path for applying paste and GUI to visualize the path for applying paste on window so that it raises workers' understanding. CONSTITUTION: In a system which uses information at the bottom of the shoes including an outer point of the shoes to generate the path for applying paste and transmit to a heel/side laster, the production process of the ideal path for applying paste at the bottom of the shoes comprises the steps of: (i) supplementing the outer point of the shoes to generate an outer line; (ii) taking the points of the path for applying paste distant in an inward normal direction of the outer line from each outer point; and (iii) supplementing the points of the path for applying paste to generate the path for applying paste.
Abstract:
PURPOSE: A 6 DOF(degree of freedom) parallel mechanism is provided to perform translational motion of a moving platform and rotation by a linear actuator for precise position control, and to apply to accurate work for multiple motion widely. CONSTITUTION: A 6 DOF parallel mechanism is composed of a moving plate placed in the upper part; a base platform(20) placed in the lower part; an external link(30) connecting the moving plate and the base plate; and an internal link(50) connecting the moving plate and the base plate by a multilink spherical joint(40). The tetrahedron structure is formed with connecting plural internal links around the multilink spherical joint. The moving plate is rotated with driving three external links in fixing three internal links connected to the multilink spherical joint. The parallel mechanism operates translational motion of the moving plate separated from rotation in a small space. A linear actuator as the internal link and the external link controls position finely, and operates accurately and finely.
Abstract:
PURPOSE: A multilink joint for connecting four links is provided to manufacture and perform conveniently by reducing assembling components with simple structure, and to operate relatively without interference with each other. CONSTITUTION: Plural disks(10,20,30) having each diameter are layered for relative motion, and combined with links(12,23,34) operating without interference. Extension lines of the links are concentrated to a point. A ball socket joint(40) is combined with the disk(10) in the middle of plural disks to rotate, and the links are fixed firmly by an assembling unit combined with the disks. Three links are connected through three disks, and four links are concentrated to a point by combining the ball socket joint in the middle with the upper connecting link. The motion range of the link is enlarged easily with adjusting the size of a groove of the disk for preventing interference between links. Plural links are concentrated on the point with increasing the number of links simply by increasing the number of the disks.
Abstract:
A method for generating an ideal cementing trajectory of a shoe sole for a heel/ side laster. A contour line of a shoe is generated from information based on contour points of the shoe sole, this information may be retrieved from a database of various shoes depending on a selected shoe style. The ideal cementing trajectory is automatically generated based on the information on the contour points, and offset inwardly from the contour line. Preferably the contour line and the cementing trajectory can be modified and stored upon request of a 10 worker. A cementing operation is performed not along the ideal cementing trajectory, but preferably through generation of an actual cementing trajectory, comprising a plurality of straight line segments. The actual trajectory is generated by setting operating points onto the cementing trajectory and linearly connecting these operating points. A maximum trajectory error is calculated between a line segment of two neighbouring points. These operating points can be adjusted so that the maximum error is smaller than a predetermined value. Preferably the contour line and cementing trajectory are generated by the use of NURBS and a computer-readable medium where in a program is recorded for executing the generation of the cementing trajectory.
