Abstract: A conveyance mechanism (1) includes: a trough (10) that conveys an article; a support member (20) to which the trough is detachably coupled, the support member including a vibrator that vibrates the trough; and a coupling member (30) that couples the trough and the support member. The trough includes a first abutting member (11) that is located on a back side of a conveyance face for conveyance of the article and abuts on the support member. The support member includes a second abutting member (21) that is plate-shaped and has a second circumferential edge (22) vertically identical to a first circumferential edge (12) that is a circumferential edge of the first abutting member. The coupling member couples the trough and the support member by fastening the first abutting member and the second abutting member with the first circumferential edge and the second circumferential edge in superposition. The second abutting member (21) is provided with a through hole (23) passing through the second abutting member.

Abstract: Problem To improve the efficiency of a combination weighing operation.
An article conveyance device 110 includes an article discharge container 10, an article conveyance mechanism 30, an article detection mechanism 60, and a control unit 90. The container 10 has outlets 20 to discharge articles A. The article conveyance mechanism 30 has feeders 40 including a first feeder 41 to an n-th feeder 4n configured to convey the articles A. The article detection mechanism 60 has sensors 70 including a first sensor 71 to an n-th sensor 7n configured to detect the articles A in the first feeder 41 to the n-th feeder 4n, respectively. The control unit 90 judges whether jamming of the articles A is occurring in the outlets 20 based on output of the article detection mechanism 60. The control unit 90 increases a conveyance intensity of some feeders receiving the articles A from places where the jamming is occurring in the outlets 20.

Abstract: It is an object of the present invention to provide a timing hopper that inhibits the occurrence of the problem that articles end up getting stuck inside the timing hopper and are not normally discharged.
A timing hopper 9 includes a first member 91, a second member 92, and a gate 9a. The first member 91 has a first opening 91a to which articles A are input. The second member 92 has a second opening 92a from which the articles A are discharged. The gate 9a opens and closes the second opening 92a. The first member 91 has a first side wall 91b and a second side wall 91c. The second side wall 91c opposes the first side wall 91b. The second member 92 has a third side wall 92b and a fourth side wall 92c. The third side wall 92b is continuously connected to the first side wall 91b. The fourth side wall 92c opposes the third side wall 92b and is continuously connected to the second side wall 91c. The height position where the first side wall 91b and the third side wall 92b are interconnected is different from the height position where the second side wall 91c and the fourth side wall 92c are interconnected.

Abstract: A weighing device is equipped with a first overload protection mechanism and a second overload protection mechanism. The first overload protection mechanism includes a first support portion disposed on a fixing member and a first section disposed on a connecting member. The second overload protection mechanism includes a second support portion disposed on the fixing member and a second section disposed on the connecting member. When a first load acts on a weigh hopper, the first support portion supports the first section from below. When a second load greater than the first load acts on the weigh hopper, the second support portion supports the second section from above at the same time that the first support portion supports the first section.

Abstract: A remedy judging system includes a weight checking device and a judgment unit. The weight checking device checks the weight of weighed product discharged from a weighing device. The judgment unit makes a judgment relating to remedies for the weighing device on the basis of “correct weight,” “overweight,” and “underweight” checking results, relative to a predetermined weight serving as a norm, obtained by the weight checking device. The judgment unit makes the judgment on the basis of determination patterns having an “underweight” checking result and at least one checking result that consecutively follows the “underweight” checking result.

Abstract: A combination weighing apparatus (1) according to one embodiment includes: a plurality of hoppers (4) to (6) that receives articles inputted from an outside, temporarily stores the articles, and discharges the stored articles downstream; a discharge chute (9) that receives the articles discharged from the hoppers and causes the articles to slide downstream; an acquisition unit (50) that acquires weight values of the articles stored in each hopper; and a control unit (30) that performs combination calculation on the basis of the weight values acquired by the acquisition unit and discharges the articles from a hopper determined by the combination calculation to the discharge chute. The discharge chute includes: a first slide surface (91) having a plurality of openings (91A); and a second slide surface (92) that covers a part of the opening and is disposed at a position on an inner side of the discharge chute with respect to the first slide surface. The second slide surface is formed continuously with the first slide surface on an upstream side, a left side, and a right side of the opening.
