るように作動する。[Function] By operating the vibrator of the vibrating type supply device 7, the small bulk articles a in the vibrating tray 5 flow out and are supplied to the weighing tray 11. This weighing tray 11 is filled with loose small items a.
When a certain amount has been fed, the weighing rod 12 with a pan tilts due to a change in the weight balance, and the weighing rod 12 moves away from the proximity switch 16, and the vibrator operation of the feeding device 7 is stopped by the signal transmitted by the switch 16, and the small bulk articles are removed. The supply of a to the weighing tray 11 is stopped. Furthermore, with the start of the tilting of the weighing rod 12, the weight ball B placed at the weighing weight determining position A rolls along the trough-like long groove 12a to the stop position B on the swing fulcrum side, and to this stop position B. Due to the rolling of the ball, the pivoting moment of the weighing rod changes greatly such that it becomes larger on the side of the tray 11 and smaller on the opposite side, and this change in the pivoting moment of the weighing rod causes the article sliding angle at which the weighing rod 12 is regulated by the stopper 15. The small articles a in the receiving tray 11 are rapidly tilted to α, breaking the static friction and being ejected and dropped into the hopper 1. Then, the weight balance of the weighing rod 12 changes so that the tray 11 side becomes lighter and the ball side becomes heavier, so the weighing rod 12 rotates to its original position (initial posture state) due to the change in weight balance after the article is discharged. At this time, the weight ball B, which is in the stop position B on the swing fulcrum side, rolls backward and returns to the weighing weight determination position A. is detected, and in response to the signal, the vibrator operation of the feeding device 7 is started and operated to feed the bulk articles to the weighing tray 11.

自動包装することが可能となる。 Incidentally, since a certain amount of small bulk articles a put into the hopper 1 are automatically packed and packaged by sealing the tube-shaped bag material P with the heat seals 2 and 3, the timing of this bagging and packaging is determined. By matching the supply and weighing timing of the small bulk articles a with the timing of supplying and weighing the small bulk articles a, it becomes possible to continuously and automatically package a predetermined amount of weighed small bulk articles a.

とするばら小物品の自動包装機。 A predetermined amount of weighed small articles a is put into the hopper 1, and the small articles a of the bag material P are dropped and fed into a tube-shaped bag material P whose bottom b is sealed.
In an automatic packaging machine, a fixed amount of small bulk articles a are automatically packaged continuously by sealing with a pair of heat seals 2 and 3 which are operated to open and close an upper receiving part to which the above-mentioned On top of the machine frame top plate 4 on which the hopper 1 is attached, there is a vibrating type supply device 7 for discharging the bulk articles a in the vibrating tray 5 by a vibrator operation, and an outlet 8 of this supply device 7.
and a weighing device 10 for receiving and weighing the small bulk articles a falling from the hopper 1,
This weighing device 10 has a weighing tray 11 on the front end side through which small bulk articles a are fed in a fixed quantity, and a gutter-like long groove 12a on the rear end side in which a ball can roll. A weighing rod 12 with a plate that rotates within a certain angle range, and the weighing rod 12 is placed in a weighing weight determination position A at the end of the long groove 12a of the weighing rod, and the weighing rod 12 is maintained in an initial posture slightly tilted backward;
When a certain amount of small bulk articles a is placed in the weighing tray 11 and the weighing rod 12 with a pan begins to tilt due to a change in weight balance, the weighing rod 12 rolls along the trough-like long groove 12a to a stop position B on the swing fulcrum side. saucer 1
The bulk articles a in the weighing rod 1 break the static friction and are discharged and dropped into the hopper 1.
In order to determine the weighing weight at which when 2 rotates back to the original position due to a change in weight balance after the article is discharged, it rolls backward from the swing fulcrum side stop position B and returns to the weighing weight determining position A. The weight ball B and the vibrator operation of the feeding device 7 are stopped when the weighing rod 12 with a plate is tilted, and the feeding device 7 is stopped when the weighing rod 12 is rotated back to its original position.
and a proximity switch 16 which issues a signal to start the vibrator operation.
