Providing a weighing apparatus that weighs an article while conveying the article, the weighing apparatus being able to calculate a proper correction value for correcting the weight measured by a measurement unit and the actual weight of the article while reducing the operating time of the weighing apparatus needed for calculating the correction value. The weighing apparatus includes a second conveyor, a load cell, and a control unit. The second conveyor receives and conveys an article. The load cell detects a weight of the second conveyor or, in a case where the second conveyor is conveying the article, a weight of the second conveyor and the weight of the article on the second conveyor and outputs a weigh signal. The control unit calculates a correction value for correcting the weight of the article detected by the load cell, based on the weigh signals output by the load cell when a reference sample is conveyed by the second conveyor for a number of times of the reference sample weighings. The control unit calculates the number of times of reference sample weighings based on the weigh signals output by the load cell when the control unit drives the second conveyor.

Providing a weighing apparatus that measures the weight of an article while conveying the article, the weighing apparatus being able to accurately infer defect factors. A weighing apparatus 100 measures the weight of an article P while conveying the article. The weighing apparatus includes a second conveyor 14 that conveys the article, a load cell 28, and a control unit 84. The second conveyor has a variable conveyance speed. The load cell detects the weight of the second conveyor or, in a case where the second conveyor is conveying the article, the weight of the second conveyor and the weight of the article on the second conveyor and outputs a weigh signal. The control unit generates statistical information from the weigh signals output by the load cell in a state in which there is no article on the second conveyor in regard to each of plural conveyance speeds. The control unit determines and outputs candidates for defect factors based on the statistical information for each of the conveyance speeds.

A weighing device (1) has: a weighing unit (WH) that weighs a weight value of an article put from an outside;a trough (21) that extends toward the weighing unit and has an open upper portion; a screw (22) that rotates in the trough (21) to convey the article put in the trough (21) toward the weighing unit; a drive portion (40) that rotates the screw (22); and a control unit (50) that controls the rotation. The control unit (50) causes the screw (22) to convey the article by switching between a first rotation in which the article is conveyed in a direction of approaching the weighing unit and a second rotation in which the article is conveyed in a direction away from the weighing unit, on the basis of a torque generated at the time of the rotation or a rotation speed of the rotation.

An X-ray inspection apparatus (1) including: an X-ray irradiation unit (6); a transport unit (5); an X-ray detection unit (7); and an X-ray shielding door (20). An inclined portion (60) that is inclined downward from the one side (left side) toward the other side (right side) in the width direction (Y-direction) when seen in the transport direction (X-direction) in the closed state is formed in at least a part of an inner surface (31) of the X-ray shielding door. In the closed state, a lower end portion (62) of the inclined portion (60) in the vertical direction is located closer to the other side (right side) of the width direction (Y-direction) than a position of an end portion of the transport unit (5) on the one side (left side) of the width direction.

Problem To improve the efficiency of a combination weighing operation.Solution An article conveyance device 110 includes an article discharge container 10, an article conveyance mechanism 30, an article detection mechanism 60, and a control unit 90. The article discharge container 10 has discharge outlets 20 and discharges, from the discharge outlets 20, articles A it is holding. The article conveyance mechanism 30 has plural feeders 40 including a first feeder 41 to an n-th feeder 4n. The plural feeders 40 convey the articles A they have received from the discharge outlets 20. The article detection mechanism 60 has plural sensors 70. The plural sensors 70 include a first sensor 71 to an n-th sensor 7n. The first sensor 71 to the n-th sensor 7n detect the presence of the articles A in the first feeder 41 to the n-th feeder 4n, respectively. The control unit 90 judges whether or not jamming of the articles A is occurring in the discharge outlets 20 based on output of the article detection mechanism 60. The control unit 90 increases a conveyance intensity of some feeders receiving the articles A from places where the jamming is occurring in the discharge outlets 20.

A packaging apparatus (100) reducing the possibility that packages inconsistent with desired specifications is manufactured due to an optional device (50) being mistakenly set to an operative or inoperative setting. A bag-making and packaging apparatus (100) operates a bag-making and packaging unit to manufacture bags (B) containing articles inside (A), and a gas replacement device (50) can be optionally attached to the bag-making and packaging apparatus (100). The bag-making and packaging apparatus (100) includes an operation control unit (96a) controlling the operation of the bag-making and packaging unit (100), a first detection unit (96c) detecting whether or not the gas replacement device is attached to the bag-making and packaging apparatus (100), a second detection unit (96d) detecting whether a setting of the gas replacement device (50) is set to an operative or an inoperative setting, a notification unit (94, 97) issuing a notification of information relating to the gas replacement device (50), and a notification control unit (96b). The notification control unit (96b) makes the notification unit (94, 97) issuing a notification that the gas replacement device (50) is set to the inoperative setting when the first detection unit (96c) detects that the gas replacement device (50) is attached to the bag-making and packaging apparatus (100) and the second detection unit (96d) detects that the gas replacement device (50) is set to the inoperative setting before the operation of the bag-making and packaging unit (100) is started.
