As shown in fig. 1, the first detecting device 400 is disposed at the first detecting position 12, and the first detecting device 400 is configured to detect whether the inner frame paper 10 exists, and select whether to send out the first rejecting signal according to a detection result. The second detection device 500 is disposed at the second detection position 13, and the second detection device 500 is configured to detect whether the inner frame paper 10 is defective and select whether to send out a second rejection signal according to the detection result.
With the above arrangement, before the inner frame paper 10 is conveyed to the first processing station 14 to form the intermediate member 20, the first detection device 400 of the first detection station 12 can first determine whether the inner frame paper 10 in the second conveying device 200 exists; after the intermediate member 20 is formed, the second detection device 500 of the second detection position 13 can determine whether the inner frame paper 10 of the intermediate member 20 is defective again, and send out a rejection signal according to the detection results of two times, so that the probability that no inner frame paper 10 or the inner frame paper 10 is damaged in the final finished product is reduced, and the yield of the finished product is improved.
