Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention reciprocates a groove-shaped article guide in small increments in the groove direction, and the aggregated articles in the guide drop and are supplied from the end of the derivative by a constant amount due to its inertia. Regarding the device.

[0002]

2. Description of the Related Art In this type of vibrating feeder, when a groove-shaped dielectric is vibrated in a horizontal direction, powdery or granular products inside the dielectric are flattened by their weight and at the same time inertial Will automatically fall from the end of the derivative. In this case, since the articles are flattened in advance, the amount of fall can be made almost equal, and it is often used as a pre-process device of the weighing device.

[0003]

[Problems to be Solved by the Invention] However, the side dishes such as chopped pickles that have irregular shapes and tend to be entangled with each other have a smaller specific gravity than powders and granules, so they are flat by horizontal vibration. However, the above-mentioned derivative is not suitable for this type of article because it tends to fall in a dumpling state from the end of the derivative.

[0004]

SUMMARY OF THE INVENTION The present invention provides for dispensing problematic articles such as chopped pickles in near-quantitative quantities.
An article supply means in which the lower machine base and the upper groove type guide are connected via a pair of parallel links which are horizontally swingable, and the machine base and the guide are connected via a vibration mechanism. In the above, a leveling plate that hangs into the other end of the bracket whose one end is fixed to the dielectric body through a pivot pin and that connects the lower portion of the pivot support pin and the machine base through a stop link. A weighing hopper disposed at the exit of the groove-shaped derivative through a weight checker between the outlet and the machine base;
A timer means for releasing the shirtter provided with the discharge port of the weighing hopper in a closed state at a constant set time, and a weighing signal of the weight checker and a time signal of the timer means are respectively inputted and within a constant time signal. And a controller that controls the output of the vibrating mechanism so that the weight checker's measured value reaches a set value.

[0005]

[Function] Since the leveling plate hung in the bracket through the pivot pin on the bracket is integral with the leveling member through the bracket, when the leveling plate is shaken horizontally by the vibrating mechanism, the leveling plate also Attempts to displace in the same direction as the derivative. However, since the middle part of the leveling plate is fixed to the machine base via the stop link, the lower end of the leveling plate moves in the direction completely opposite to the moving direction of the dielectric, and the article on the dielectric is hit. At the same time as destroying the mass of articles, the articles are swept evenly and inertia causes a nearly constant quantity of articles to be fed to the weighing hopper.

The weight of the articles stored in the weighing hopper is measured by the weight checker and simultaneously input to the controller, while the set time by the timer is input to the same controller to measure the weight checker within the set time. The controller controls the movement of the vibrating mechanism so that the value becomes the set value.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a groove type dielectric 13 is provided on a machine base 10 through a pair of swingable parallel links 11 and 12.
Is supported, and the dielectric 13 and the vibration mechanism 14 are connected. The vibration mechanism includes a crank lever 16 fixed to the shaft of the motor 15, and the crank lever and the inductor 1
Since 3 and 3 are connected via the arm 17, the derivative 13 vibrates in small directions in the directions of arrows A and B.

An intermediary plate 23 is hung by a pivot pin 22 on the abscissa to the other end of a bracket 21 which supports one end on the upper surface of the inductor 13 via a pin 20 on the ordinate, and the intermediary plate and the machine base 25 are connected to each other. Are connected via a stop link 24, and a leveling plate 26 is fixed below the intermediary plate 23 with screws 27. Therefore, as shown in FIG. 3, when the pivot pin 22 is displaced together with the inductor 13 in the direction of the arrow A, the leveling plate 26 is pushed back by the bulging of the stop link 24, and the articles 18 in the inductor are swept and leveled. . In this case, in order to prevent unnecessary pressure on the article 18 from acting on the back surface of the leveling plate 26 in FIG.
It is desirable to install 1.

As shown in FIG. 2, the leveling plate 26 has four comb-shaped plow bars 33 hanging downward in parallel. This plow stick 3
3 is effective for crushing a lump of an article with low resistance.

As shown in FIG. 1, the outlet 34 of the derivative 13
A weighing hopper 35 arranged in the lower region of the weight checker 36 is supported on the machine base 10 via a weight checker 36, and an output circuit 37 of the weight checker 36 is connected to a controller 38. The shirt 39 for closing the lower outlet of the weighing hopper 35.
When the switch 41 is closed by the timer 42 by connecting the motor 40 with the motor 40, the motor 40 causes the shirt 39
Open up. The accumulated time of the timer 42 is input to the controller 38 via the output circuit 43 and the weight checker 36 always operates.
The controller 38 sends a command signal to the vibration mechanism 14 via the circuit 39 so that the replenishment weight to the weighing hopper 35 reaches the set value within the set time by the timer 42. To do.

As shown in FIG. 4, the amount of vibration of the vibrator 14 is controlled so that the measured weight value of the weight checker 36 reaches the set value within the set time of the timer 42, that is, the closing time of the shirt 39.
