Abstract: An abnormality detection method includes: acquiring a determination target image that is an image of a determination target object to be regularly aligned while standing, which is a cylindrical container; creating a difference image emphasizing a difference between an image of a normal determination target object regularly aligned and the determination target image; calculating a multi-segmentation error of the difference image to determine a maximum value of the multi-segmentation error; and determining whether the determination target object is normal or abnormal in accordance with the maximum value.

Abstract: Provided is a container processing system capable of improving a speed of processing containers with a simple configuration and providing a compact production line. The container processing system (10) includes a container conveyer (20) having a container conveying path (21a) that conveys containers (C) arranged in a row and a container processor (40) that performs processing on the containers (C) in a container processing area (A2) set lateral to a container transfer area (A1) set in a segment of the container conveying path (21a). The container conveyer (40) includes a container carrier (21) conveying the containers (C) arranged in the row along the container conveying path (21a) and a container transferrer (22) moving a container row including the plurality of containers (C) arranged in the row in the container transfer area (A1) toward the container processing area (A2).

Abstract: Provided is a container processing system that inhibits, a processing liquid that is used to process containers from being attached to peripheral equipment. A container processing system (10) includes a chamber (30) having in an inside thereof a gas flow control chamber (35) and a container processor (40) including container treaters (51) and (61) that perform processing on containers (C). The chamber (30) has container processing openings (36) and (37) making the gas flow control chamber (35) and an outside of the chamber (30) communicate with each other. The container treaters (51) and (61) are configured to perform, from inside the gas flow control chamber (35), processing on the containers (C), which are inserted into the chamber (30) through the container processing openings (36) and (37), or on the containers (C), which is opposed to the container processing openings (36) and (37), outside the chamber (30).

Abstract: Provided are a coating method and a coating device capable of making the coating film thickness of a coating agent uniform with a simple structure. Provided is a coating method, the coating; method including moving a spray gun (20) and the container (C) relative to each other to insert the spray gun (20) into the container (C), and ejecting the coating agent onto the container inner wall surface from the spray gun while adjusting a relative positional relationship between the spray gun (20) and the container (C) in the gun longitudinal direction, rotating the spray gun (20) and the container (C) relative to each other about an axis along the gun longitudinal direction, and changing at least one of a relative rotation speed between the spray gun (20) and the container (C) and an angle range of the rotation in accordance with the shape of the container (C).

Abstract: An apparatus (31) for correcting the bending of the molten resin includes a temperature-adjusting device (32) arranged surrounding an extrusion passage (12) for extruding the molten resin (8) of an extrusion die head (7) along the direction of extruding the molten resin (8), a measuring means (33) for measuring the horizontal position of the molten resin (8) extruded from an extrusion opening (20) of the extrusion passage (12), and a control means (34) for controlling the temperature-adjusting device (32) based on the results measured by the measuring means (33).

Abstract: A compression-forming system comprising a molten resin mass-feeding device equipped with the holding portions for holding the molten resin masses, a compression-forming machine equipped with the metal molds, and a molten resin mass position detector, wherein said molten resin mass position detector is a temperature sensor, and said temperature sensor measures the temperature of a portion on the outer side of an allowable range in which the molten resin masses are fed to the metal molds, and judges the presence of the molten resin masses on said portion by the temperature of said portion of the metal molds to detect that the molten resin masses are defectively handed over.

Abstract: To provide a metal mold for forming a preform decreasing the hitting of metal molds at a portion where a slide insert metal mold and a cavity metal mold undergo the sliding yet maintaining the pressure. The metal mold (33) for forming the preform includes a slide insert metal mold (36) split into at least two for forming at least a nozzle portion of the preform, wherein a pressure is maintained by using a fitting portion which includes a preform-forming portion of the slide insert metal mold (36) coupled together from the split state and a cavity metal mold (34). Auxiliary fitting portions (40a, 40b) where the slide insert metal mold (36) and the cavity metal mold (34) undergo the sliding is formed at a position of not forming the preform separate from the fitting portion that includes the preform-forming portion.

Abstract: [Problem] To provide a metal mold for forming a preform decreasing the hitting of metal molds at a portion where a slide insert metal mold and a cavity metal mold undergo the sliding yet maintaining the pressure. [Means or Solution] The metal mold 33 for forming the preform includes a slide insert metal mold 36 split into at least two for forming at least a nozzle portion of the preform, wherein a pressure is maintained by using a fitting portion which includes a preform-forming portion of the slide insert metal mold 36 coupled together from the split state and a cavity metal mold 34. Auxiliary fitting portions 40a, 40b where the slide insert metal mold 36 and the cavity metal mold 34 undergo the sliding is formed at a position of not forming the preform separate from the fitting portion that includes the preform-forming portion.
