Abstract: First guide pipes are disposed on both sides of blasting areas, and second guide pipes are disposed on both sides of the blasting area. A wire rod W is inserted through the first guide pipes and the second guide pipes, penetrating in a conveying direction of the wire rod W. The diameter of each of first insertion holes of the first guide pipes and second insertion holes of the second guide pipes is gradually reduced toward the downstream side in the conveying direction. The second guide pipe is installed in a state in which the downstream-side end portion in the conveying direction is inserted into the first insertion hole from the inlet side of the first guide pipe.

Abstract: A shot treatment apparatus and a shot treatment method that can efficiently detect operational abnormalities and signs of operational abnormalities, and that can further take countermeasures based on the detected signs of operational abnormalities. This shot treatment apparatus is provided with a storage portion, a nozzle, a transport path, a compressed-air supply portion, a negative pressure gauge, an abnormality detection unit, an abnormality response unit, and a control unit. Shot material is transported to the nozzle by negative pressure generated in the interior of the nozzle. The negative pressure gauge is disposed on the transport path by which the shot material is transported. The abnormality detection unit detects “operational abnormalities” and “signs of operational abnormalities” based on detection results from the negative pressure gauge. The abnormality response unit operates based on the detection results from the abnormality detection unit. The control unit controls the operations of this abnormality response unit.

Abstract: An inspection device is a device that inspects the appearance of a target, including: an imaging device configured to image the target from a first direction; an illuminating unit configured to apply light to the target; and a controller configured to acquire a first inspection image by causing the imaging device to image the target to which light is applied from a first position, to acquire a second inspection image by causing the imaging device to image the target to which light is applied from a second position, and to inspect an appearance of the target based on the first inspection image, the second inspection image, and a reference image. The first position and the second position overlap each other when viewed from the first direction.

Abstract: Provided is a technique that allows an operator or the like to easily perceive a tendency of defects which are present in molds or patterns. A display device displays a result of inspection of a plurality of molds or a plurality of patterns which are inspection target objects. The display device classifies the inspection target objects into a plurality of groups, generates, for each of the plurality of groups, a heat map image from a result of defect inspection of one or more of inspection target objects which are classified into the each of the plurality of groups, the heat map image representing a spatial distribution of defect occurrence frequencies; and causes a display to display one or more of the heat map images generated, the one or more heat map images corresponding to one or more groups specified by a user from among the plurality of groups.

Abstract: Provided is the technique that allows an operator or the like to grasp a failure of a mold to be worked in the work area. An inspecting device inspects each of a plurality of molds conveyed along a conveyance path with use of image data generated by a sensor that captures an image of each of the plurality of molds. A display control device is configured to carry out: a storage process in which inspection results of the individual molds are stored in a memory; a determination process in which one or more molds satisfying a predetermined condition of a positional relation to a display are determined from among the plurality of molds conveyed along the conveyance path; and a display control process in which one or more inspection results of the respective one or more molds having been determined in the determination process are displayed on the display.
