A weighing and packaging apparatus () includes a packaging unit (), a weighing unit (), and a frame (). The packaging unit () includes a film transport mechanism () that transports a film (F) in a film transport direction, a detachable former (), a former seat () that supports the former (), and a sealing mechanism (). The weighing unit () is positioned on an upper side in a vertical direction of the packaging unit (), and supplies articles (A) to be packaged to the packaging unit (). The frame () supports at least the weighing unit (), and includes legs including a first front leg (), a first back leg (), a second front leg (), and a second back leg (). A movable portion () including the former seat () moves in a maintenance mechanism movable space (PM) when the former () is detached. All of the legs are located so as to avoid a leg prohibited space (PP).

Weighing and packaging apparatus

Provided is a dispersion and supply apparatus and a combination weighing apparatus capable of uniformly supplying articles to a plurality of positions from a dispersion table. A dispersion and supply apparatusincludes an acquisition unitthat acquires a load amount of an article on a dispersion table, a calculation unitthat calculates a deviation in a loading state of the article based on the load amount acquired by the acquisition unit, and a control unitthat controls a driving unitsuch that a conveying direction of the article on the dispersion tableis changed based on the deviation in the loading state of the article calculated by the calculation unit

Dispersion and supply device and combination weighing device

Provided is a combination weighing device whereby a physical quantity for assessing the quantity of articles loaded on a conveyance path for conveying articles to a weighing part can be accurately sensed in non-contact manner in order to appropriately control the supplying of articles to the weighing part, without the sensing being affected by a structure above the combination weighing device and/or side walls provided to sides of the conveyance path. A combination weighing device () is provided with cameras () and a plurality of radial feeders () for conveying articles to weighing hoppers (). The radial feeders () have side walls () for surrounding sides of an article conveyance path. The side walls () extend upward and along a conveyance direction of the articles. The cameras () sense, in non-contact manner, a physical quantity for assessing a quantity of articles loaded on the radial feeders (). The cameras () sense the physical quantity from above the radial feeders (), and in an obliquely downward direction from an upstream side to a downstream side in the conveyance direction of the articles.

Combination weighing device including conveyors and cameras

The present invention provides a dispersing feed device including: a dispersion table adapted to receive articles supplied from above and to feed the articles to multiple sections on the periphery of the dispersion table; a first elastic unit inclinedly connected to the dispersion table, the first elastic unit having a first natural frequency; a second elastic unit connected to the dispersion table inclinedly in a direction different from the inclination direction of the first elastic unit, the second elastic unit having a second natural frequency which is different from the first natural frequency; and at least one vibrating source adapted to vibrate the dispersion table through the first and second elastic units.

Dispersing feed device and combination weighing device comprised of at least two elastic units inclined in different directions with different natural frequencies that can vary a feed direction of articles thereon by changing the driven vibration frequency
