ARTICLE CONVEYANCE DEVICE AND COMBINATION WEIGHING DEVICE
Problem To improve the efficiency of a combination weighing operation.
Solution 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 article discharge container 10 has discharge outlets 20 and discharges, from the discharge outlets 20, articles A it is holding. The article conveyance mechanism 30 has plural feeders 40 including a first feeder 41 to an n-th feeder 4n. The plural feeders 40 convey the articles A they have received from the discharge outlets 20. The article detection mechanism 60 has plural sensors 70. The plural sensors 70 include a first sensor 71 to an n-th sensor 7n. The first sensor 71 to the n-th sensor 7n detect the presence of the articles A in the first feeder 41 to the n-th feeder 4n, respectively. The control unit 90 judges whether or not jamming of the articles A is occurring in the discharge 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 discharge outlets 20.

VIBRATING CONVEYOR
For tuning a vibrating conveyor having an electric vibrator that drives a vibration element connected to a conveying unit of the vibrating conveyor for oscillating the conveying unit to a mechanical resonance frequency f.sub.R of the vibrating conveyor, an electric drive unit varies the frequency f.sub.v of a AC drive voltage (u.sub.v) in a given frequency range, measures a current consumption of the electric vibrator unit for different applied frequencies f.sub.v of the AC drive voltage (u.sub.v) and using the frequency f.sub.v with the lowest current consumption of the electric vibrator unit as frequency f.sub.v of the AC drive voltage (u.sub.v) for operating the vibrating conveyor.
Vibrating machine with a bearing device and method of operating a vibrating machine
A vibrating machine including a first machine part that vibrates in operation, a second machine part connected to an installation area of the vibrating machine, and a vibratory drive. A resilient bearing is arranged between the machine parts and has at least one air spring per support point and at least one compressed air reservoir fluidically connected to the air spring. A throttle is switched intermediate the air spring and the compressed air reservoir. The first machine part bearing has a resonant or natural frequency lower than an operating frequency of the vibrating machine. The bearing system has a frequency-dependent lower stiffness level with high damping at low frequencies, an upper stiffness level with low damping at higher frequencies, and a transition zone at an intermediate transitional frequency. The throttle is dimensioned such that the transitional frequency is close to, preferably slightly above, the resonant or natural frequency.
