Abstract: A combination weighing device (1) performs combination weighing of at least two different articles, weighing hoppers (5) and booster hoppers (6) are divided into at least two groups on the basis of types of the articles, a controller (1) sets each of the groups to either a first mode or a second mode, in the group set to the first mode, the articles retained in the weighing hopper (5) are discharged to a receiver (9) via the booster hopper (6), and in the group set to the second mode, the articles retained in the weighing hopper (5) are discharged to either the booster hopper (6) or the receiver (9).

Abstract: A combination weighing apparatus includes a plurality of hoppers a conveying unit; a weighing unit; a controller; and a setting unit, the controller executing the combination weighing based on a measured value acquired in a cycle in which the combination weighing failed and corresponding to the articles that were forcibly discharged from at least some of the hoppers and measuring values associated with the respective hoppers weighed in a cycle after the cycle in which the combination weighing failed.

Abstract: A weighing device includes a conveyance unit which conveys an article, a hopper which receives the article conveyed by the conveyance unit, temporarily holds the article, and then discharges the article downstream, a detection unit which detects the article between a conveyance end of the conveyance unit and the hopper, and a control unit which controls driving of the conveyance unit. When the detection unit does not detect the article at a start of driving of the conveyance unit, the control unit drives the conveyance unit for a first period. When the detection unit detects the article at a start of driving of the conveyance unit, the control unit drives the conveyance unit for a second period longer than the first period.

Abstract: The present invention provides a combination weighing apparatus (1) capable of eliminating the need for memo paper for messages and reminders. A memory (22) of a control unit (20), which comprehensively controls the operation of the combination weighing apparatus (1), is provided with a memo information storage unit (22b) that stores memo information. In addition, the control unit (20) is provided with a retrieval control unit (21a) that retrieves memo information stored in the memo information storage unit (22b), and a display control unit (21b) for displaying the memo information retrieved by the retrieval control unit (21a). Furthermore, a touch screen (30), which is a memo information input means for inputting memo information, is connected, capable of sending and receiving signals, to the control unit (20).

Abstract: A weighing and packaging system includes a weighing unit, a packaging unit, a dropping path, a display unit, a determination unit and a display control unit. The dropping path is disposed between the weighing unit and the packaging unit. The display unit includes a display screen to display an image representing the weighing unit, the dropping path and the packaging unit. The determination unit is configured to determine whether the articles are present in the weighing unit, the dropping path, and the packaging unit, respectively. The display control unit is configured to display an indicator indicative of the articles on the image representing the weighing unit, the dropping path and the packaging unit displayed on the display screen according to a determination result by the determination unit.

Abstract: The present invention provides an article manufacturing apparatus that even a user unfamiliar with the article manufacturing apparatus can operate appropriately.
