A hopper attachment structure is provided that allows a hopper to be removably attached to a driving unit. The hopper has an outlet in a body thereof and a gate driven to open and close by the driving unit. The outlet of the hopper is allowed to open and close with the gate. The driving unit has an engaging protrusion and a support protrusion. The hopper further has an attachment bracket extending from the body. The attachment bracket has a hook portion engageable with the engaging protrusion and also has a contact portion allowed to contact the support protrusion. The hopper is attachable to the driving unit by having the hook portion of the attachment bracket engaged with the engaging protrusion of the driving unit and by further having the contact portion of the attachment bracket supportably contact the support protrusion of the driving unit.

An article transport feeder is equipped with an article transporter removably attachable to a vibratory head of a vibration mechanism. The article transport feeder is also equipped with a fastening unit having an operation lever. The fastening unit rotates the operation lever to retainably engage the article transporter with the vibratory head by fastening. The article transport feeder is further equipped with a movable coupling member having a spindle elastically deformable. The movable coupling member is coupleable to the fastening unit and allowed to move along with the rotation of the operation lever. The spindle is elastically deformable by moving the movable coupling member along with the rotation of the operation lever of the fastening unit to elastically retain the engagement of the article transporter with the vibratory head.

A combination weighing device is provided that includes a plurality of article suppliers disposed in juxtaposition with each other and adapted to transport and supply articles to a plurality of weighing units. The combination weighing device further includes an article transporter adapted to drop and supply the transported articles from a direction intersecting with a direction of transport of the articles by the article suppliers, and an article split-and-guide member adapted to split, drop and guide the articles in a direction of juxtaposition of the article suppliers.

Combination weighing apparatus with a plurality of article suppliers

A combination weighing device is provided that discharges, from a hopper, an article oversupplied into and received by the hopper and that collects the article using the collection container. The combination weighing device includes an oversupplied article retainer disposed at a position on a discharge path for the article to be discharged from the hopper and collected by the collection container. The oversupplied article retainer has a collection chute and a blocking shutters and temporarily retains the article guided to flow downward using the collection chute and the blocking shutter.

Combination weighing device

A combination weighing apparatus includes a retaining hopper that retains an article and supplies the retained article onto a transport path. The retaining hopper has a coupling portion adapted to be inserted in along the support rails and pulled off from support rails disposed in a pair. The retaining hopper is thus supportable by the support rails and is readily mounted to and dismounted from the apparatus without using any tool for cleaning and other purposes.
