Detailed ways

In order to further explain the technical means and effects of the present invention to achieve the intended purpose of the invention, below in conjunction with the accompanying drawings and preferred embodiments, the specific aspects of the sound wave detection cup bottom detection system, detection method and detection module proposed according to the present invention will be described below. Embodiments, methods, steps, features and effects thereof are described in detail below.

As shown in Figure 1A, it is a detection system 100 for detecting the bottom of a cup by sound waves according to an embodiment, which includes: a feeding module T1, a vacuum suction ball 20, a conveying module 30, a voiceprint detection module 50, a rejecting module 60 and Collection module 70 .

As shown in FIG. 1A , the feeding module T1 sequentially delivers at least one cup to be tested 10 from the outlet, wherein the cup to be tested 10 has a cup mouth 11 and a cup bottom 12 . In the manufacturing and testing process of paper cups, a feeding tube can be used as the feeding module T1, and the cups 10 to be tested are sequentially sent out from the outlet of the feeding tube.

As shown in FIG. 1A , the vacuum suction ball 20 is rotatably arranged at the outlet of the feeding module T1 . The vacuum suction ball 20 sucks the mouth 11 of the cup body 10 to be tested sent out from the feeding module T1 , and rotates to drive the cup body 10 to be tested.

As shown in Figure 1A, the delivery module 30 is fixed below the vacuum suction ball 20, and the delivery module 30 has a conveyor belt 31 to transport the cup body 10 to be tested that falls from the vacuum suction bulb 20 and the cup opening 11 is upward, and the delivery module 30 There are detection area A1, rejection area A2 and collection area A3 in sequence.

As shown in Figure 1A, the voiceprint detection module 50, which is fixed above the conveyor belt 31 in the detection area A1, emits sound waves to the cup bottom 12, receives the echo (reflected wave) reflected by the cup bottom 12, and generates a detection Voiceprint. And according to the detected voiceprint, it is determined whether the cup 10 to be tested is a good cup 10G or a bad cup 10B.

The way for the voiceprint detection module 50 to determine whether the cup 10 to be tested is a good cup 10G or a bad cup 10B can be to compare the detected voiceprint with the pre-stored qualified voiceprint or unqualified voiceprint, and according to the comparison It is judged that each cup 10 to be tested is a good cup 10G with a good bottom 12 or a bad cup 10B with a bad bottom 12 .

As a qualified voiceprint for comparison reference, the cup bottom 12 of several good cup bodies 10G can be pre-detected by the voiceprint detection module 50, and the detected voiceprints can be generated and pre-stored as qualified voiceprints for comparison reference. Voiceprint.

The rejecting module 60 may have at least one rejecting blower 61 to blow off the defective cups 10B from the conveyor belt 31 under control.

The reject fan 61 can be controlled by the voiceprint detection module 50 , or can be controlled by a controller or a processor or a computer or a PC to blow the defective cups 10B off the conveyor belt 31 . When the rejecting fan 61 is controlled by a controller or processor or computer or PC, the controller or processor or computer or PC is also connected to the voiceprint detection module 50 at the same time, and rejects the fan 61 according to the detection result of the voiceprint detection module 50. control.

Also shown in Fig. 1A and Fig. 1B, collecting thing module 70, it is to be fixedly installed in collecting area A3, and has collecting material fan 71 and material collecting pipe 72, and collecting material fan 71 is to be transported into collecting material by conveyer belt 31. Good cups 10G in zone A3 are blown into collection pipe 72 from conveyor belt 31 for collection.

In a word, as described in the previous embodiments, the detection system 100 for detecting the cup bottom by sound waves can use the voiceprint detection module 50 to correctly detect the cup bottom 12 of each cup body 10 to be tested, and the defective cup body 10B can be removed by the rejection module 60. Blow off the conveyor belt 31 and blow off the box body 40 from the reject port 42, while the good cup body 10G can be collected by the collection module 70, ensuring the good manufacturing quality of the paper cup and the use safety of the paper cup.

As shown in FIG. 2 , the detection system 100 for detecting the bottom of a cup with acoustic waves may further include a box body 40 , which covers a part of the conveying module 30 , and has a material feeding port 41 and a rejecting port 42 . The detecting area A1 , the rejecting area A2 and the collecting area A3 of the conveying module 30 can be covered by the box body 40 . In addition, the conveyor belt 31 of the conveying module 30 can transport the cup body 10 to be tested from the feed port 41 into the box body 40, and the reject module 60 can be controlled to remove the bad cup body 10B from the reject port 42 to leave the box body. 40.

The casing 40 as shown in Figure 2 can still avoid the interference of external noise or air flow, so that the detection system 100 for sound wave detection of the bottom of the cup can detect the accuracy of the cup bottom 12 of the cup body 10 to be measured without being affected. Influence.
