Sorting and supplying apparatus for plurality of packaging products

A sorting and suppling apparatus for a plurality of packaging products, the apparatus comprising:

• a plurality of defect sorting units spaced by a predetermined distance in a line and each including a sorting conveyor configured to measure a weight of a product that is input from a product input part and transfer the product in a non-defective product transfer direction or a defective product transfer direction,
• a weight measuring part formed on one side of the sorting conveyor and configured to measure the weight of the input product,
• a forward-reverse rotation motor configured to rotate the sorting conveyor forward or backward, and
• a control unit configured to receive a weight measurement value signal of the product from the weight measuring part and determine whether a weight measurement value is within a preset non-defective value range so as to control forward-backward rotation of the forward reverse rotation motor;
• and
• a shortage supplement unit which includes a supplement conveyor mounted on a front side of the defect sorting unit and configured to transfer the product in a supplement direction so as to supplement products with as many products as the number of sorted and separated defective products of the products transferred from the defect sorting unit,
• a driving motor configured to drive a conveyor belt of the supplement conveyor in the supplement direction, and
• a control unit configured to receive a signal of the number of the defective products from the defect sorting unit and control operation of the driving motor to supplement products with as many products as a preset number of non-defective products,
• wherein each of the sorting conveyors of the defect sorting units includes a driving roller configured to receive power of the forward reverse rotation motor and configured to be axially rotated, a driven roller disposed on a side opposite to the driving roller and spaced by a predetermined distance to be collinear with the driving roller, and a conveyor belt configured to surround the driving roller and the driven roller and slide forward or backward, and
• the weight measuring part includes a weight detecting part disposed adjacent and parallel to a lower surface of the conveyor belt and configured to detect the weight of the input product,
• a connection part which has an upper end portion connected with one side of the weight detecting part and a lower end portion extending downward,
• a cell-upper plate connected with a bottom of the connection part and configured to receive a weight detection value of the weight detection part through the connection part,
• a load cell which is connected with the cell-upper plate, measures the weight detection value of the product transferred to the cell-upper plate, and transfers a weight measurement value signal to the control unit,
• the weight measuring part further includes a head block provided between a vertically upper surface of the load cell and one lower surface of the cell-upper plate and configured to connect the vertically upper surface of the load cell and the one lower surface of the cell-upper plate to certainly provide the weight detection value of the product, which is transferred to the cell-upper plate, to the load cell,
• a plurality of partitions are provided on a surface of the conveyor belt of the shortage supplement unit and are spaced by a predetermined distance in a driving direction to partition the conveyor belt by each product to be supplemented, and
• the supplement conveyor includes a lifting part configured to be vertically lifted to a predetermined height.
