Abstract

A combination weighing apparatus includes a timing hopper, a frame, and a support member. The support member is a member attached to the frame and moves a position of the timing hopper between (1) a first mounting position at which the timing hopper receives and retains objects to be weighed and (2) a second mounting position related to attachment and detachment of the timing hopper without changing a fixed state of the timing hopper with respect to the support member. A movement direction in which the timing hopper moves from the first mounting position to the second mounting position intersects a removing direction in which the timing hopper fixed at the predetermined position is removed from the support member.

First claim

The invention claimed is:

1. A combination weighing apparatus comprising:
a plurality of weighers that measures objects to be weighed;
a controller that combines weights of the measured objects to be weighed and selects specific weighers corresponding to a weight value within a desired range;
a collecting chute that collects and discharges the objects to be weighed discharged from the selected weighers a timing hopper that temporarily retains the discharged objects to be weighed, and then discharges the objects to be weighed;
a frame that directly or indirectly supports at least one of the weighers, the controller, the collecting chute, and the timing hopper; and a support that is a member attached to the frame and to which the timing hopper is fixed at a predetermined position, wherein
the support is capable of movement between (1) a first mounting position at which the timing hopper receives and retains the objects to be weighed and (2) a second mounting position related to attachment and detachment of the timing hopper, the movement of the support being relative to the frame and occurring while the timing hopper is fixed at the predetermined position,
the timing hopper is capable of movement between the predetermined position and a position that enables removal from the support, the movement of the timing hopper being relative to the support, and
a movement direction in which the support moves from the first mounting position to the second mounting position intersects a moving direction in which the timing hopper moves from the predetermined position to the position that enables removal.

2. The combination weighing apparatus according to claim 1 , further comprising
a grip used when the support is moved, wherein
the support comprises a pair of supports, the pair of supports face each other in the movement direction in which the support moves from the first mounting position to the second mounting position, on a plane orthogonal to the substantially vertical direction, and
the grip is attached to a one of the supports, the one of the supports being disposed on a near side of a user in the movement direction in which the support moves.

3. The combination weighing apparatus according to claim 1 , wherein the frame has an opening opened to at least an upper side around the second mounting position.

4. The combination weighing apparatus according to claim 1 , wherein
the timing hopper has a pin engaged with the support,
the support has an end portion fixing the timing hopper by the pin being engaged therewith, and
among regions imaginarily formed around the support, (1) a first region is a region in which the pin is engaged with the end portion, (2) a second region subsequent to the first region is a region in which the pin slides on the support and is a region in which the timing hopper is removable from an upper side of the support, and (3) a third region subsequent to the second region is a region in which the timing hopper is removable from the upper side and a lower side of the support.
