In a weighing and packaging system 1, an analysis unit 714 ascertains a fluctuation tendency in a time series for a measured value of information pertaining to a time in which a group of articles C passes between a light-projecting unit 27a and a light-receiving unit 27b of a detection sensor 27 of a bag-making and packaging unit 3, and adjusts a transverse seal timing or a cycle time in accordance with the fluctuation tendency. As a result, articles can be prevented in advance from being bitten during transverse sealing.

A combination weighing apparatus includes a timing hopper, a frame, and a support member. The support member is a member attached to the frame and moves a position of the timing hopper between (1) a first mounting position at which the timing hopper receives and retains objects to be weighed and (2) a second mounting position related to attachment and detachment of the timing hopper without changing a fixed state of the timing hopper with respect to the support member. A movement direction in which the timing hopper moves from the first mounting position to the second mounting position intersects a removing direction in which the timing hopper fixed at the predetermined position is removed from the support member.

A combination weighing device includes a conveying unit configured to convey articles, a controller configured to perform combination weighing of the articles, and an interface configured to receive an input of information from an operator. The controller has a first operation mode including a first control parameter that defines a conveying operation of the conveying unit and is automatically set in the device, and a second operation mode including a second control parameter that defines the conveying operation of the conveying unit and is set based on the information input from the interface, and when the interface receives an input of the information during an operation of the conveying unit in the first operation mode, the controller makes a transition from the first operation mode to the second operation mode, and controls the operation of the conveying unit using the second control parameter.

A combination scale includes a pedestal having, at its center, an opening that vertically penetrates therethrough, and a center base body equipped with linear feeders and hoppers. The center base body is supported on the pedestal through leg portions. The pedestal has an upper surface formed so as to incline downward toward an outer end thereof.

A weighing mechanism (1) includes: a hopper (105) configured to store an article; a hanger (2) on which the hopper is hung; a mass weighing instrument (3) configured to weigh the article stored in the hopper; a connection member (4) that connects the hanger and the mass weighing instrument; a main body member (6) having a through hole (5) through which the connection member penetrates; a diaphragm (7) that connects an outer edge of the connection member and an inner edge of the through hole of the main body member; and a waterproof cover (8) that covers at least part of the through hole between the diaphragm and the hanger. The waterproof cover is detachably attached only to the hanger among the main body member and the hanger.

A management system (1) manages a production line (2) including a processing apparatus (20) and an inspection apparatus (40). The management system (1) includes: a control unit (61) that estimates a processing time at which a defective food is processed by the processing apparatus (20) based on a time at which the defective food determined as a defective product by inspection by the inspection apparatus (40) is inspected; and a storage unit (62) that stores processing information of the processing apparatus (20) related to the processing time estimated by the control unit (61) such that the processing information can be output.
