Detailed description of the invention
In order to the technical characteristic to utility model, object and effect have understanding clearly, now contrast accompanying drawing and detailed description of the invention of the present utility model is described, label identical in the various figures represents identical part.
In this article, " one " not only represents " only this ", also can represent the situation of " more than one ".
In this article, " schematically " expression " serves as example, example or explanation ", not should by being described to any diagram of " schematically " in this article, embodiment is interpreted as a kind of preferred or have more the technical scheme of advantage.
In this article, the restriction in the mathematics of " parallel " etc. non-critical and/or geometry meaning, it also can comprise it will be appreciated by those skilled in the art that and manufacture or use the error allowed time this product (or method).
Fig. 1 is for illustration of a kind of schematically embodiment of screening plant of article.As shown in Figure 1, the screening plant of article, it comprises a weight sensor 10, rejecting mechanism 20.Wherein, weight sensor 10 can detect the weight Wt of tested article 60, if the weight Wt of tested article 60 does not reach weight preset value, rejecting mechanism 20 can reject this tested article.
Wherein, rejecting mechanism 20 comprises a comparing unit 21, air injection unit 22 and a propelling movement cylinder 26.Wherein, comparing unit 21 is connected with weight sensor 10 signal, and air injection unit 22 all can be connected with comparing unit 21 signal with propelling movement cylinder 26.
In comparing unit 21, have two weight preset value W1 and W2, wherein W1 is less than W2.After weight sensor 10 senses tested article 60 weight Wt, the weight Wt data of tested article 60 can be transferred to comparing unit 21.If when tested article 60 weight Wt is less than weight preset value medium and small weight preset value W1, namely during Wt < W1, as shown in Figure 2, comparing unit 21 can export a jet signal S1, this jet signal S1 can control air injection unit 22 and be communicated with a source of the gas 50, with to tested article 60 gas jet; If when tested article 60 weight Wt is not less than the medium and small weight preset value W1 of weight preset value but is less than another weight preset value W2, namely during W1≤Wt < W2, as shown in Figure 3, comparing unit 21 can export one and push signal S2, pushes signal S2 and can control to push the reciprocating motion of cylinder to push tested article 60.
