Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hopper device for various uses, and more particularly to a hopper device that is optimal for taking out individual ultra-thin objects and the like.

The biggest problem with ordinary hoppers is that the flow of the recipients is inhibited by a kind of jamming phenomenon caused by mutual friction between the recipients.

On the other hand, also in the case of vibrator hoppers.

The reality is that it has not yet been possible to reliably eliminate the phenomenon of receptor jamming and stagnation as described above.

In particular, in the case of any of the above hoppers, the acceptor (+,!
There is nothing that has been developed that allows for manual feed.
Therefore, it is desired to develop a hopper that can handle this function.

This invention was made as a result of intensive research in response to the above-mentioned sushi.

The main object of the present invention is to provide a hopper device that can prevent objects in the hopper from stagnation due to mutual friction and keep the objects in a smooth flowing state at all times. .

The first object of the present invention is to apply a force to the received object in the hopper while it is being sent out, so that the sending out of the received object is always +
The hopper equipment provides a smooth and efficient 6W14 heating process.

Another object of the present invention is to provide a hopper device j'(j') that is capable of sequentially and individually discharging objects received in the hopper.

Preferred embodiments of the present invention will be described below with reference to the drawings.

First, the structure of the hopper device shown in FIG. The chute hole 3 is formed to open laterally.

A plunger 4 is inserted into the vertical grunge hole 2 to open and close the chute hole 6 and to induce fluid movement in the receiving material S in the hopper 1.

This plunger 4 is located at the upper end of a tapered surface 4aY that coincides with the partially tapered surface 1a in the hopper 1 in the lowest position, and between it and the upper hole wall surface 2a on the open side of the chute hole 6 in the vertical pushing hole 21C. A receptor alignment hole 2° is formed for introducing the receptor S into the array.

Therefore, the pusher 4 has a step wall 4b which becomes the bottom wall of the alignment hole 2'. The stepped wall has a receptor Sy! in the alignment hole 21. It is formed as an inclined surface that directs the transfer to the L-chute hole 6.

Such plunger 4 (- is driven up and down by air actuator 5 to open and close chute hole 6, and
It causes the flow of money. The details will be described later.

Above, in the example of the vortex formation in the m1 diagram, the alignment hole 2' is the hopper 1
The chute hole 5 is set to have a width that allows the receivers SY in the alignment hole 2' to be introduced into a vertically aligned state, and the chute hole 5 is set to have a width that allows the receivers SY to be placed in a vertical line. ', l is set to an aperture width that accommodates the receptor S.

Thus, the actuator 5 moves the plunger 4 up and down by 1
1 fb, the plunger pushes up the group of receptors S in the hopper 1 when it rises.

For this reason, the group of receptors that tend to stagnate due to friction between the receptors Sf near the bottom of the hopper 1 is loosened.

Therefore, the group of receptors S in the hopper 1 always flows smoothly and falls into the alignment hole 21.

The receptors S group in this alignment hole 2' are in a vertical line,
The vertical movement of the plunger 4 applies dynamic friction to each receiving object.

Due to the dynamic friction, the object 541U inside the alignment hole 21
The mutual stagnation phenomenon is eliminated before it happens.

Therefore, as the plunger 4 descends, the chute hole 6 becomes 1
51'! Upon release, the lowest object in the alignment hole 2' is introduced into the chute hole 6.

(Thus, the group of recipients S in the hopper 1 always causes a smooth flow movement, and the individual recipients S K in the alignment hole 2'
By applying the tHIJ friction, each time the plunger 4 opens and closes the chute hole 6, the recipients S 61j' are successively and smoothly introduced into the chute.

Therefore, even if the receptor S is a needle-like ultra-fine object,
Its capabilities can be fully utilized as a hopper device that individually supplies the recipient materials to, for example, a precision production line.

In the hopper device shown in FIG. 2, the upper hole wall 4i2a of the chute hole 6 in the alignment hole 21 extends outward in the hole diameter direction than the lower hole wall surface 2b.

2b are formed in a stepped manner with the chute hole 3 in between.

In this case, there is no fear that the receiver 8ta:rqa will be trapped between the step y4b of the plunger and the upper edge 3IL of the opening end of the chute hole B when the plunger 4 is raised, and the inner part of the alignment hole 21 is completely eliminated. Three types of receptors with different diameters! l- can be introduced, providing versatility.

As described above, this invention has the special effect that the objects in the hopper can always be kept in a smooth rocking state by the vertical movement of the plunger, and the objects can be sent out individually in order θ by the dynamic friction of the plunger. can get.
