| Abstract | 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. |

| Claim | A combination weighing apparatus, comprising: a retaining hopper that retains an article and supplies the article retained onto a transport path; and support rails disposed in a pair, the retaining hopper comprising a coupling portion adapted to be inserted in along the support rails and pulled off from the support rails, the retaining hopper being supported by the support rails by having the coupling portion inserted in and coupled to the support rails. The combination weighing apparatus according to claim 1, wherein the coupling portion is a flange formed at an upper end of the retaining hopper, and the retaining hopper is supportably suspended from the support rails by having the flange inserted in and coupled to the support rails. The combination weighing apparatus according to claim 2, wherein the support rails comprise: a first stopper on a rear-end side in a direction of the retaining hopper being inserted, the first stopper being adapted to contact and restrict the retaining hopper from moving in the direction of the retaining hopper being inserted after the retaining hopper is inserted to a certain position; and a second stopper on a front-end side in the direction of the retaining hopper being inserted, the second stopper being adapted to contact and restrict the retaining hopper from moving in a direction of the retaining hopper being pulled off after the retaining hopper is inserted to a certain position. The combination weighing apparatus according to claim 3, wherein the flange is formed at an outer peripheral position of a rectangular throw-in port of the retaining hopper, the flange formed is formed along the directions of the retaining hopper being inserted and pulled off and is inserted in and engageable with the support rails, an end of the flange on a side in the direction of the retaining hopper being inserted is allowed to contact the first stopper, and an end of the flange on another side in the direction of the retaining hopper being pulled off is allowed to contact the second stopper. The combination weighing apparatus according to one of claims 1 to 4, wherein the support rails are disposed at a lower end part of a retaining tank located in an upper direction of the retaining hopper. The combination weighing apparatus according to one of claims 1 to 4, further comprising: a plurality of supply units that are linearly arranged next to each other, the plurality of supply units each comprising the retaining hopper and a linear feeder that receives the article supplied from the retaining hopper; and a plurality of weighing units that are linearly arranged next to each other, the plurality of weighing units each comprising a set of a supply hopper and a weighing hopper that are vertically disposed, wherein the supply hopper retains the article supplied from the linear feeder of each of the supply units and discharges the article retained, and the weighing hopper retains the article discharged from the supply hopper and measures a weight of the article retained. The combination weighing apparatus according to claim 5, further comprising: a plurality of supply units that are linearly arranged next to each other, the plurality of supply units each comprising the retaining hopper and a linear feeder that receives the article supplied from the retaining hopper; and a plurality of weighing units that are linearly arranged next to each other, the plurality of weighing units each comprising a set of a supply hopper and a weighing hopper that are vertically disposed, wherein the supply hopper retains the article supplied from the linear feeder of each of the supply units and discharges the article retained, and the weighing hopper retains the article discharged from the supply hopper and measures a weight of the article retained. |
