A combination weighing apparatus includes a first stepping motor, which has a heat emitting surface, and a load cell. The load cell has a strain element and an electrical circuit including a first temperature-sensitive resistor. The strain element has a first thin portion to which a first strain gauge is attached, a second thin portion to which a second strain gauge is attached, and a first central portion disposed between them. The first central portion has a first surface that opposes the heat emitting surface of the first stepping motor and a second surface that does not oppose the heat emitting surface. The first temperature-sensitive resistor is secured to the second surface.

A weighing apparatus is configured to weigh articles, and includes a conveyance unit, a weighing unit, and a control unit. The conveyance unit is configured to convey the articles. The weighing unit is configured to output an original signal corresponding to forces acting on the conveyance unit. The control unit is configured to control the conveyance unit, and execute a selection process during a period from when the control unit sends a stop instruction to the conveyance unit to when the conveyance unit stops. The selection process includes applying a plurality of digital filters to the original signal, and selecting one of the digital filters to be used during a weighing operation of the articles based on results of applying the digital filters to the original signal.

There is a need to reduce wasteful time and energy for checking the proper functioning of a checking apparatus. A weighing apparatus includes hoppers that retain items, load cells that measure the weights of the items, a control unit, and a communication unit that receives signals from outside. The control unit causes the items to be discharged from the hoppers when the weights of the items satisfy a proper weight discharge condition. When the communication unit receives an improper weight item request signal relating to a check of the items discharged from the hoppers, the control unit causes the items whose weight is a weight deviating from the proper weight discharge condition to be discharged from the hoppers.

A weighing apparatus ( 1 ) according to an embodiment includes: adjacent hoppers ( 12 A, 12 B); and a sorting mechanism ( 20 ) disposed between the adjacent hoppers ( 12 A, 12 B), the sorting mechanism ( 20 ) sorting an article given from outside into one of the adjacent hoppers ( 12 A, 12 B), in which the sorting mechanism ( 20 ) includes a rotator ( 21 ) rotatable around a rotation shaft ( 21 R), the rotation shaft ( 21 R) and a central axis ( 21 C) of the rotator ( 21 ) are not parallel, the rotator ( 21 ) rotates when the article abuts on the rotator ( 21 ), and the rotator ( 21 ) does not rotate when the article does not abut on the rotator ( 21 ).

A training image storage device that stores training images for learning of an image related to an article, the training image storage device includes: an imaging unit configured to capture an image of the article; a determination unit configured to determine whether a captured image of the article is an outlier image; and a storage unit configured to store at least a part of the captured images as a training image. The determination unit determines whether the captured image is the outlier image based on a trained model related to the article and features of the captured image. The storage unit stores, as the training image, the captured image that is determined not to be the outlier image among a plurality of the captured images.

A conveyance apparatus includes: a conveyance unit; a posture changing unit provided on one side portion of the conveyance unit, configured to be switchable in advancing-retracting positions between a first state being advanced toward an other side portion of the conveyance unit and a second state being retracted toward the one side portion from the first state, and configured to change a position or a posture of an article being conveyed; a detection unit provided upstream of the posture changing unit, and configured to detect a position or a posture of the article; and a control unit configured to control the advancing-retracting position between the first state and the second state. The control unit determines whether to cause the article and the posture changing unit to interfere with each other, and controls the advancing-retracting position of the posture changing unit according to a result of the determination.

A flap folding device includes a first member that folds a pair of first flaps toward an inside of an opening of a cardboard box, a second member that folds a pair of second flaps toward the inside of the opening, and a holding member including a rod-shaped or plate-shaped elongated portion extending along a long side direction of the opening, and pressing and holding the pair of folded first flaps by the elongated portion. The second member folds the pair of second flaps in a state where the pair of first flaps are held by the holding member after the first member folds the pair of first flaps. The holding member is attached to be swingable.

A folding apparatus includes: a transport unit; and a folding unit disposed above the transport unit and configured to fold a front flap and a rear flap into the inside of an opening of a cardboard box. The transport unit stops transport of the cardboard box when the cardboard box is positioned below the folding unit. The folding unit includes a first abutting portion and a second abutting portion, a first mechanism configured to drive the first abutting portion and the second abutting portion and make the front flap and the rear flap stand upright from below in conjunction with an operation of the first abutting portion and the second abutting portion, and a second mechanism configured to fold the front flap and the rear flap standing upright toward the inside of the opening by moving the first abutting portion and the second abutting portion along a transport direction.

An X-ray inspection apparatus includes an irradiation unit configured to irradiate a conveyed article with X-rays, an X-ray sensor unit including a sensor unit configured to detect the X-rays by photon counting and an image generation unit configured to generate an image based on a detection result output from the sensor unit, and a control unit having a first mode for inspecting the article based on the image and a second mode for determining a state of the X-ray sensor unit at a time of time delay integration driving, in which the control unit is configured to compare a first image generated based on a detection result output from the sensor unit at a time t 1 with a second image generated by integrating detection results output from the sensor unit until a time t 2 after the time t 1 to determine the state of the X-ray sensor unit.

An X-ray inspection device includes first and second conveyors, an X-ray irradiation unit, an X-ray line sensor, and a control unit. The first and second conveyors are configured to convey first and second articles at first and second conveying speeds, respectively. The second conveying speed is different from the first conveying speed. The X-ray line sensor is configured to detect amounts of X-rays transmitted through the first and second articles at a timing based on the first conveying speed. The control unit is configured to generate a first X-ray image of the first article, and a second X-ray image of the second article, and to inspect the first and second articles, respectively. The control unit is configured to correct an effect of a speed difference between the first and second conveying speeds in inspection of the second article based on the second X-ray image.
