  • Publication number: 20150000484
    Abstract: Disclosed herein is a method of manufacturing one or more kinds of rectangular unit pieces from a long base material sheet at a predetermined angle through a continuous cutting process using a cutting frame, the method including (a) manufacturing a base material sheet of a laminate structure having two or more stacked sheets and winding the base material sheet on a roll, (b) continuously feeding the base material sheet, wound on the roll, (c) cutting the fed base material sheet using a cutting frame having cutters mounted or formed therein in a structure in which the cutters correspond to rectangular unit pieces to be manufactured, the cutters being arranged such that the shapes of opposite side ends of the cutters coincide with each other when the cutters are successively arranged, the cutting being carried out while the base material sheet is partially overlapped such that a length (‘pitch’) for a one-time cutting process is equal to a spacing distance between the opposite side ends of the cutters in the lo

  • Publication number: 20140106118
    Abstract: Disclosed herein is a cutter frame including a plurality of cutters for cutting one or more kinds of rectangular unit pieces having a relatively small size from a rectangular base material at a predetermined inclination, the cutters being mounted or formed in the cutter frame such that the cutters correspond to the rectangular unit pieces, two of the rectangular unit pieces being arranged mainly in the inclination direction such that the rectangular unit pieces are in contact with each other at one side of each rectangular unit piece, wherein, on the assumption that imaginary vertex coordinates of a leftmost end are (Ax, Ay), and imaginary vertex coordinates of a rightmost end are (Bx, By), when the rectangular unit pieces coincide with each other at a left or right side of each rectangular unit piece, vertex coordinates (B?x, B?y) of the rightmost end are greater than the imaginary vertex coordinates (Bx, By) of the rightmost end based on the imaginary vertex coordinates (Ax, Ay) of the leftmost end in an ar

  • Publication number: 20110048209
    Abstract: Disclosed herein is a cutting frame including a plurality of cutters for cutting two or more kinds of rectangular unit pieces having relatively small sizes from a rectangular base material at a predetermined inclination, the cutters being mounted or formed in the cutting frame such that the cutters correspond to the rectangular unit pieces, wherein the cutters are formed in the cutting frame in an array structure of the rectangular unit pieces in which largest-sized rectangular unit pieces are arranged at a central part of a base material based on the height of the base material in the longitudinal direction of the base material, and small-sized rectangular unit pieces are arranged above and below the largest-sized rectangular unit pieces.

  • Publication number: 20100288100
    Abstract: Disclosed herein is a cutting frame including a plurality of cutters for cutting one or more kinds of rectangular unit pieces having a relatively small size from a rectangular base material at a predetermined inclination, the cutters being mounted or formed in the cutting frame such that the cutters correspond to the rectangular unit pieces, wherein the cutters are mounted or formed in the cutting frame in an array structure of the rectangular unit pieces in which the rectangular unit pieces adjacent to one another at each side thereof have a vertex coincidence ratio equivalent to less than 50%.

  • Patent number: 7528715
    Abstract: A vehicle dispatch system enables optimal dispatch of a plurality of vehicles with information of available vehicles from transportation company terminals and information of orders from client terminals under restrictive conditions such as vehicle sizes, minimum loading rates, and a maximum number of assignment locations, based on transportation regions preset in consideration of transportation times, past order quantities, and order congestion degrees, such that a relevant vehicle can perform delivery of freight within a predetermined transportation region to minimize a total transportation cost for each transportation region. The system minimizes a delivery distance of each vehicle, increases a loading volume of the vehicle to reduce an empty rate of vehicles, and minimizes the number of dispatched vehicles, thereby reducing the total transportation cost.
