In order to enable those skilled in the art to better understand the technical features of the present invention, the present invention will be further described in detail below in conjunction with the drawings and embodiments.

Please refer to Fig. 1 and Fig. 2, the present invention proposes a kind of empty bag rejecting system 1, and it is arranged on the conveying device 10, and the packaging device 20 is installed on the conveying device 10; The packaging device 20 is used to pack the objects to be packaged n1 conveyed by the conveying device 10. Considering that the packaging device 20 operates in a continuous packaging manner, the corresponding objects to be packaged n1 are arranged at equal intervals by the conveyor The device 10 transports to facilitate packaging by the packaging device 20; as shown in Figure 1, in this embodiment, the correct target n1 to be packaged is two pieces of products packaged into one package. However, it is only an example and is not limited thereto.

Based on the above, the empty bag rejecting system 1 includes: a thickness sensor 11, which is installed on the conveying device 10 and before the packaging device 20. 10 Conveying a plurality of n1 to be packaged, the thickness sensor 11 is arranged at equal intervals corresponding to each of the above mentioned n1 to be packaged, so the end face of the conveying device 10 below the thickness sensor 11 is carried out at equal intervals. Detect to generate the sensing thickness, and generate abnormal sensing signals corresponding to the sensing thickness less than the preset thickness; as shown in Figure 1, the normal sensing thickness should be the thickness of two pieces of products. When sensing, the thickness sensing Under the detector 11, when there is only one piece of product (abnormal label n2) or no product (no package n0), a sensing thickness smaller than the preset thickness will be detected, and an abnormal sensing signal will be generated; After being packaged by the packaging device 20, the packaging of the two products is the normal packaging label. N1, the package with only one piece of product is marked N2 with abnormal package, and the package with no product is marked N0 with empty package.

The rejecting device 13 is installed on the conveying device 10 and behind the packaging device 20. The packaging label N1 packaged by the packaging device 20, the abnormal packaging label N2 or the empty packaging label N0 will pass through the rejecting device 13. If there is no abnormality, it will directly Through the rejecting device 13, if it is an abnormal packaging label N2 or an empty packaging label N0, the rejecting device 13 will reject the abnormal packaging label N2 or empty packaging label N0 packaged by the packaging device 20 before passing through the rejecting device 13 according to the rejecting signal. .

One end of the recycling conveyor belt 30 is connected to the conveying device 10 corresponding to the rejecting device 13, and the abnormal packaging label N2 or empty packaging label N0 rejected by the rejecting device 13 enters the recycling conveyor belt 30, and the recycling conveyor belt 30 is sequentially equipped with an unsealing device 40 and a recycling device. The device 50, the recycling conveyor belt 30 sends the rejected abnormal packaging labels N2 or empty packaging labels N0 to the unsealing device 40 for unsealing, so as to form an opening and become the NC of the unsealed abnormal packaging labels, and send it to the recycling device by the recycling conveyor belt 30 50 storage, because the NC with the abnormal packaging label has an opening, it is convenient to take out the product in the package, so as to facilitate the subsequent repackaging operation.

The controller 12 is installed on the conveying device 10 and is electrically connected to the thickness sensor 11 and the rejecting device 13 . The controller 12 receives the abnormal sensing signal and sends the rejecting signal to the rejecting device 13 after an interval.

Further, the rejecting device 13 can output gas according to the rejecting signal; in more detail, the rejecting device 13 can have a gas delivery pipeline 131, the gas delivery pipeline 131 is connected to the pneumatic device, and the gas is provided through the pneumatic device, so that the rejecting device 13 will remove the abnormal packaging target N2 or N0 of the empty packaging label is sprayed.

The above interval time is calculated by the controller 12 according to the distance between the thickness sensor 11 and the rejecting device 13 and the conveying speed of the conveying device 10 .

In order to enable the recycling conveyor belt 30 to receive the rejected abnormal packaging labels N2 or empty packaging labels N0, the rejecting device 13 preferably rejects the abnormal packaging labels N2 or empty packaging labels N0 in the direction of the recycling conveyor belt 30; The structure is such that the abnormal packaging labels N2 or empty packaging labels N0 rejected by the rejecting device 13 are guided to the recycling conveyor belt 30 corresponding to the guiding structure via the guiding structure.

Based on the above, the empty bag rejecting system 1 provided by the present invention can detect the abnormal packaging label n2 or the non-packaging label n0 through the thickness sensor 11, and control the rejecting device 13 through the controller 12 to detect the abnormal packaging label Rejection of N2 or empty packaging labels N0 to achieve the effect of automatically detecting and eliminating abnormal packaging labels N2 or empty packaging labels N0; in addition, the removed abnormal packaging labels N2 or empty packaging labels N0 will enter the recycling conveyor belt 30 and send to Go to the unsealing device 40 for unsealing, and then send it to the recycling device 50 for storage, so that the products in it can be taken out and rearranged to be put back into the conveying device 10 for repackaging, so as to achieve the effect of material recycling and repackaging.
