Abstract

PURPOSE:To discharge works at a constant rate by concentrically fitting a cylindrical hopper to a cylindrical bowl, and by projectedly providing a blade on one side periphery in the turning direction of a discharge opening which has been providing at one place on the bottom outer circumference of the hopper, so that the turning progress of the works can be impeded. CONSTITUTION:A cylindrical hopper 7 in which works 3 are filled is concentrically erected and fixed on the bottom of a cylindrical bowl 2. At one place on the bottom outer circumference of the hopper 7, a rectangular discharge port 8 is provided, and on one side periphery of the discharge port 8 on the turning direction side of a feeder, a circular-arc shape blade 9 for impeding the turning progress of the works 3 is projectedly provided. And the discharge quantity of works 3 is controlled by lifting or lowering the gate 10 of the discharge port 8. When the works 3 are filled in the hopper 7 and then the feeder 5 is turned, the turning progress of the works 3 discharged from the discharge port 8 is impeded by the blade 9, so that the works 3 are gradually discharged at a constant rate. Thus, the works can be smoothly and successively fed to the upper and lower rails 4 are contact intervals.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a hopper of an electromagnetic rotary parts feeder.

(Prior Art) As shown in FIG. 2, an electromagnetic rotary parts feeder uses alternating current to generate vibrations based on the intermittent rotational adsorption of a cylindrical ball 2 by an electromagnet 1, thereby moving a workpiece 3 placed into the ball 2 into the ball. It is sequentially fed on a spiral rail 4 provided on the inner surface of the peripheral wall.

(Problem to be Solved by the Invention) The balls 2 of the electromagnetic rotary parts feeder 5 are jammed on the spiral rail 4 provided on the inner surface of the peripheral wall due to the shape of the work 3 even if there is a capacity to accommodate the work 3. For example, when the workpieces 3 are cylindrical, several workpieces 3 may be packed vertically across the width of the rail 4 as shown in FIG. It gets caught and the following workpiece 3 becomes jammed, making it impossible to move forward. This is because by putting a large amount of workpieces 3 into the ball 2, a large number of standing workpieces 3 are generated. Therefore, even if the clogging of the work 3 is cleared each time, the supply capacity of the parts feeder 5 cannot be utilized to 100%. In other words, the work 3 put into the ball 2 cannot be completely fed, and only about 5% remains. It's something to put away.

For this reason, the workpiece 3 may be introduced into the ball 2 little by little,
As shown in FIG. 5, the ball 2 is equipped with a spare ball 6,
The work 3 placed here was sequentially fed into the ball 2. However, the former method is time-consuming, and the latter method makes it difficult to set the timing for supplying the workpiece 3 into the ball 2. Furthermore, in both methods, the amount of workpiece 3 in ball 2 suddenly increases intermittently, so the interval at which workpiece 3 is fed changes.

SUMMARY OF THE INVENTION An object of the present invention is to provide a hopper for feeding workpieces into a ball of an electromagnetic rotary parts feeder such that a constant amount of workpieces is always accommodated in the ball.

(Means for Solving the Problems) In order to solve the above problems, the hopper of the electromagnetic rotary parts feeder of the present invention has a cylindrical hopper attached concentrically to the cylindrical ball of the electromagnetic rotary parts feeder. A discharge port is provided at one position on the outer circumference of the lower end of the hopper, and a blade is provided protruding from one side edge of the discharge port on the side in the direction of rotation of the feeder.

(Function) In the hopper of the electromagnetic rotary parts feeder of the present invention configured as described above, when the upper feeder filled with the work is driven, the work is discharged from the discharge port on the outer periphery of the lower end. Since a blade is protruding from one side edge of the feeder rotating side at the outlet to prevent the rotation of the workpiece, the workpiece is not discharged all at once into the ball, but is gradually discharged in a fixed amount, and the workpiece is gradually discharged into the ball. The amount of workpiece is always constant, with no excess or deficiency.Therefore, the workpiece moves smoothly without getting stuck on the spiral rail on the inner surface of the ball peripheral wall, and without getting caught on the upper or lower rails and causing subsequent workpieces to become jammed. Sequentially sent at regular intervals.

(Embodiment) An embodiment of the hopper of the electromagnetic rotary parts feeder of the present invention will be explained with reference to FIG.
This electromagnetic parts feeder is based on intermittent rotational suction of a cylindrical ball 2 (by vibration) and sequentially feeds a workpiece 3 placed into the ball 2 on a spiral rail 4 provided on the inner surface of the ball peripheral wall. 5, a cylindrical hopper 7 for filling the workpiece 3 is installed and fixed concentrically at the bottom of the bowl 2, and a rectangular discharge port 8 is provided at one location on the outer periphery of the lower end of the hopper 7, An arc-shaped blade 9 that obstructs the rotational progress of the workpiece 3 is protruded from one side edge of the discharge port 8 on the side in the rotation direction (arrow direction) of the feeder.
is formed by cutting and raising the discharge port 8. A gate 1O is provided on the upper inner surface of the discharge port 8 so as to be adjustable up and down, and the amount of the workpiece 3 discharged from the discharge port 8 is adjusted by moving the gate 1O up and down.

The hopper 7 of the electromagnetic rotary parts feeder 5 of the embodiment configured as described above is filled with the workpiece, in this example, the clad contact material 3 for header processing, and then the parts feeder 5
When driven, the clad contact material 3 discharged from the discharge port 8 on the outer periphery of the lower end of the hopper 7 is prevented from rotating by an arc-shaped blade 9 protruding from one side edge of the discharge port 8 on the side where the feeder rotates. The cladding contact material 3 is not discharged all at once into the ball 2, but is gradually discharged in a constant amount, so that the amount of the clad contact material 3 in the ball 2 is always constant, with no excess or deficiency. Therefore, the clad contact material 3 smoothly and sequentially moves on the spiral rail 4 on the inner surface of the peripheral wall of the ball 2, without getting caught on the upper and lower rails 4 and causing the subsequent clad contact material 3 to get stuck. It is sent at regular intervals and input into a required header processing machine (not shown).

(Effects of the Invention) As can be seen from the above explanation, according to the hopper of the electromagnetic rotary parts feeder of the present invention, the workpiece can be gradually discharged into the ball, and the amount of workpieces in the ball can be kept constant (always constant). Therefore, the workpieces can be smoothly fed one after another at regular intervals without getting jammed on the spiral rail on the inner surface of the peripheral wall of the ball, making full use of the feeding capacity of the electromagnetic rotary parts feeder.
