Abstract

PURPOSE:To make it possible to ensure the supply of articles one by one from a lightweight article supply device, by manipulating a pair of separated air jet ports and a suction port which are formed in an article supply passage, in combination so as to repeat the suction of articles into the passage, the advance inhibition for the next article, the conveyance of the preceding article and the suction of the next article. CONSTITUTION:A first air jet port 5 and a second air jet port 3 orthogonal to the first air jet port 5, having therebetween a space having width which is slightly narrower than that of articles, are provided in an article passage 1 in a body 8. A suction port 4 having a diameter greater than that of the first air jet port 5 is provided coaxially with the latter. With this arrangement, when air is jetted from the first air jet port 5, an article 11 is sucked into the passage 1. When the article reaches the suction port 4 and is stopped, the entrance of the article 11a is inhibited by the jetted air, Then the operation is changed over into jetting by the second jet port 3 so as to restrain the motion of the articles subsequent to the article 11a which is then fed to a dropping port 2. With the repetition of the above-mentioned steps, it is possible to feed the articles 11 one by one.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a product supply method, and particularly to a product supply method for sequentially supplying relatively lightweight products.

[Prior art and its problems]

2. Description of the Related Art Conventionally, there has been a product supply method for conveying and supplying relatively lightweight products using a flow of air.

However, in conventional air flow conveyance, products are conveyed continuously and cannot be conveyed and supplied one by one because they are conveyed by a continuous air flow. It is difficult to transport only a predetermined number of products, and there is a problem in that it is impossible to reliably transport and supply the required number of products.

The second invention solves the problems of the conventional method as described above, and provides a product supply method that can reliably transport and supply products one by one using air flow. The purpose is to

[Means for Solving the Problems] In order to solve the above problems, the present invention provides air flow ejected from two jet ports and an air flow sucked into one suction port. This is a product supply method in which the first product is suctioned into the product passage by an air flow ejected from one of the jet ports, and reaches the upper surface of the suction port to apply a suction force. ejecting air from the other outlet to prevent a second product from being drawn into the product passage by this air flow and the air flow not drawn into the inlet; After this, the jetting from the negative spout is stopped, and
The first product is further conveyed into the product passage by an air flow from the other jet port, and the second and subsequent products are sequentially conveyed in the same manner.

[Effect]

By adopting the above-mentioned means, this invention can reliably separate the products that have passed through the product passage one by one.
This makes it possible to count the products and to reliably supply the required number of products.

〔Example〕

An embodiment of the invention shown in a concave form will be described below.

1 to 3 show an apparatus for performing the product supply method according to the present invention, and FIG. 1 is a front view of the cormorant apparatus;
FIG. 2 is a cross-sectional plan view of the device, and FIG. 3 is a side view.

A product passage 1 bored in the body 8 opens at the end of the body 8, extends horizontally inward, and communicates with a product drop hole 2 that opens downward on the back side. has a width and height that allow one product to pass through, and the product drop hole 2 has a shape that allows the product to fall as it is after moving horizontally through the product path 1. ing.

The product passage 1 has a first air outlet 5 extending from the top surface of the body 8 and a second air outlet 3 extending from the side surface of the body 8 and perpendicular to the first air outlet. In this case, the second air outlet 3 is on the inlet side of the product passage 1, and is further coaxial with the first air outlet 5. At the same time, an air inlet 4 having a larger diameter than the first air outlet 5 is provided, and the air in the product passage 1 is blown out to the outside of the body 8 through this air inlet 4. ing.

Next, a case in which products are supplied using the above-mentioned apparatus will be explained.

First, as shown in FIG. 4, the product passage 1 of the body 8 of the device
and a product drop hole 2 communicating with the product passage 1.
A transport path 12 is connected to each.

In the state shown in FIG. 4(1), first, the air 6 ejected from the first air ejection port 5 passes through the product passage l and is exhausted via the air intake port 4.
In the product passage 1, there is an air flow 9a directed inward from the end surface.
This airflow 9a causes the first product 11, which is moved in the direction of the arrow 10a through the conveyance path 12, to be conveyed into the product path 1.

When the transported first product 11 reaches the air intake port 4 and partially blocks it, the first product 11 stops at that position and , a part of the air 6 ejected from the first air ejection port 5 moves inside the product passage 1 without being discharged through the air intake port 4, creating an air flow 9b directed toward the entrance of the product passage l. The second product 11a is discharged from the product passage 1, and the second product 11a moves backward as shown by the arrow 10b by the air flow 9b at this time, and is no longer conveyed into the interior of the product passage 1.

Next, as shown in FIG. 4(3), when the air 7 is ejected from the second air ejection port 3, this air flow generates an acting force in the direction of conveying the product, and the first air ejection port 5
Together with the air flow 9b due to the
On the other hand, the first product 11 is protected against the action of the air 6 by the first air outlet 5 and the action of the air 7 by the second air outlet 3. It is maintained in the state shown in the figure in balance with the force.

Next, if the flow of air 6 from the first air outlet 5 is cut off in the above state, the second air outlet 3 will appear as shown in FIG. 4 (4).
The first product 11 moves forward as shown by the arrow 10d by the airflow 9d of the air 7 from the air 7, and is conveyed to the product drop hole 2.
On the other hand, the movement of the following products 11a, 11b1, . . . is regulated by the air flow 9d.

The above action is reversed, and after the products are sequentially transported through the product path 1, they are passed through the product drop hole 2 into the transport path 1.
2, the products are reliably supplied one by one, and any number of products can be counted and supplied as needed.

〔Effect of the invention〕

Since this invention takes the above-mentioned means, the products are transported by air flow, and the products are not transported continuously, but are reliably separated and transported one by one, making it easy to count the products. This method has excellent effects such as easy transportation and the ability to transport only the required number of products.
