Definitions

  • the present invention relates to an automated quality control system developed for inspection household glass products such as ovenware, cornered products, bowls and storage boxes made of borosilicate, soda-lime and crystal glasses against manufacturing defects.
  • the quality control methods employed in the state of the art are sorted according to defects at the end of the cooling process completely by manual inspection and human eye, wherein the quality control process takes place depending on the decision made by the operator by interpreting certain quality control criteria based on experience.
  • This manual method of the prior art causes varying interpretations from one operator to another, and thus delivery of the defective products to the user depending on the perspective of the operator due to the fact that glass products are sorted according to defects completely by manual inspection and human eye.
  • Said invention discloses perform ing the inspection and recording by means of cameras via transm itting a diffused beam of light for detecting the flaws in glass bottles. Thus, the flaws on the bottles can be detected from different directions.
  • Said invention discloses at least one camera and illumination apparatus for testing glass objects which are distanced at certain intervals, for use as a testing device in order to test transparent objects, in particular glass bottles, for automatically detecting manufacturing faults.
  • the transparent objects arranged on a linear plane are scanned by at least one or more cameras and the faults thereon are detected.
  • the quality control system consists of 9 cameras, 2 light sources, and two separate control sections, wherein the defect inspection criteria can be adj usted and the quality control assessment can be stably performed over these criteria. Thus, different interpretations of the quality control criteria on the same product are prevented .
  • the suff icient lighting is ensured using one or more f ixed light sources within the system and images are taken from the angles in which the measurement is desired to be made using one or more cameras. This, in turn , inspects quality control errors resulting from the quantity of light and the viewpoint to the product.
  • the newly developed system allows sorting the defective products at the rate of
  • I t is aimed by developing the quality control system according to the invention to:
  • Fig. 1 Schematic view of the quality control system along the tunnel.
  • the glass products (1 ) such as ovenware, cornered products, bowls and storage boxes made of borosilicate, soda-lime and crystal glasses are fed to the annealing lehrs or tempering units through the automatic line subsequent to being formed in press/press blowing machines at the hot end.
  • the products exiting the annealing lehrs or tempering units are transferred to the quality control system according to the invention over the conveyor (2) in a single row.
  • the quality control system operates as a defect inspection system consisting of at least 9 cameras (3, 4, 5 and 6) , at least 2 f ixed light sources (7) , and two separate control sections.
  • the bottom surface and side surfaces of the glass product (1 ) are inspected by means of at least one bottom surface camera (3) , at least two side surface cameras (4) , and at least one f ixed light source (7) .
  • the entry of the product to the quality control system is determined by a photocell (8) disposed in the entry of the system and this product (1 ) is monitored until it gets out of the system .
  • the f ixed light source (7) and the cameras (3 and 4) are activated by the signals coming from the photocell (8) used within the system .
  • the images recorded by the cameras (3, 4, 5 and 6) are processed by the control algorithm depending on the speed of the conveyor (2) belt and the product (1 ) image is formed in the computer system (1 0) .
  • These recorded images are processed in the computer ( 1 0) in the quality control system .
  • I t is possible with these processed images to detect the defects on the glass product (1 ) which are formed during or after the manufacturing process by way of the difference in the contrast.
  • I f there is any defect on the glass product ( 1 ) the system stores the defective product in its memory to be rejected at the exit of the machine.
  • the defective or non-defective products (1 ) having undergone the f irst control section are transferred to the second control section by the conveyor (2) .
  • at least one f ixed light source (7) disposed between the two-section conveyor (2) is illum inated by being triggered by a trigger photocell (9) when the product ( 1 ) assumes the suitable position ; in the meantime, the images are recorded by triggering the at least four corner cameras (6) facing the corners of the product (1 ) in the advancing direction , and if any, at least two handle cameras (5) facing the handle portion of the product (1 ) .
  • the same process is also performed by the cameras (5 and 6) at the other side facing the handle and corners of the product ( 1 ) , if any.
  • the cameras (6) facing the corners of the product ( 1 ) are located such that they will correspond to the top of each corner.
  • the cameras (5) facing the handles of the product ( 1 ) are located above the cameras (6) facing the corners in an angular manner.
  • the images thus taken are recorded in the memory of the computer system (1 0) . These recorded images are processed by the system and the defective products are detected by way of the difference in the contrast .
  • the defective products ( 1 ) are stored in the memory to be rejected at the exit of the machine. At the exit of the machine, the defective products (1 ) are rejected while the non-defective products ( 1 ) are delivered to the packaging section by the conveyors (2) according to the incom ing information from both control sections of the quality control system .
  • the fact that the process in which the defective products (1 ) are rejected and the non-defective products are sent to the packaging section is conducted accurately by the machine is ensured by monitoring the product (1 ) entering the machine until the exit of the machine.
