DETAILED DESCRIPTION

[0033] In order to make the technical solution of the utility model clearer, the utility model is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] Example 1

[0035] Combination Figure 1-4The present embodiment provides a preform detection device, comprising: a mandrel head detection component 1, comprising a first camera 11 and a first backlight source 12 located on different sides, and also comprising a first trigger sensor 13; a stain detection component 2, comprising a first shooting unit 21 and a backlight source 1 22 located on different sides, and a second shooting unit 23 and a backlight source 2 24 located on different sides, and also comprising a second trigger sensor; a controller connected to the first camera 11, the first backlight source 12, the first trigger sensor 13, the first shooting unit 21, the backlight source 1 22, the second shooting unit 23, the backlight source 2 24 and the second trigger sensor.

[0036] Specifically, when the first trigger sensor 13 detects the preform 6, it transmits a detection signal to the controller. The controller turns on the first camera 11 and the first backlight source 12, and controls the first camera 11 to take pictures of the preform 6 and perform image analysis. If the preform 6 is found to be skewed, dropped or stuck, the first camera 11 transmits a rejection signal to the controller. The preform detection device of the present application cooperates with the rejection component 3 of the relevant bottle blowing machine to reject the problematic preform 6, so that the relevant bottle blowing machine can reject defective bottles in time.

[0037] When the second trigger sensor detects the preform 6, the detection signal is transmitted to the controller, and the controller turns on the first shooting unit 21, the backlight source 1 22, the second shooting unit 23 and the backlight source 2 24, and controls the first shooting unit 21 and the second shooting unit 23 to take pictures of the preform 6 and perform image analysis. If stains are found on the preform 6, the first shooting unit 21 and the second shooting unit 23 both transmit rejection signals to the controller. The preform detection device of the present application cooperates with the rejection component 3 of the relevant bottle blowing machine to reject the problematic preform 6, thereby further enabling the relevant bottle blowing machine to reject defective bottles in time. The first shooting unit 21 and the second shooting unit 23 perform dual shooting, which is convenient for making the shooting comprehensive and preventing missed detection.

[0038] The first trigger sensor 13 may be a non-contact sensor such as a photoelectric sensor; the second trigger sensor may be a non-contact sensor such as a photoelectric sensor; and the controller is preferably a programmable logic controller, ie, a PLC.

[0039] Further, such as Figure 1 The spindle head detection component 1 also includes a first mounting frame 14, and the first camera 11, the first backlight source 12 and the first trigger sensor 13 are all connected to the first mounting frame 14, and the first mounting frame 14 is used to carry the first camera 11, the first backlight source 12 and the first trigger sensor 13.

[0040] Further, such as Figure 1The first camera 11 and the first backlight source 12 are both movably and tightly connected to the first mounting frame 14. The movably and tightly connected connection facilitates the adjustment of the height of the first camera 11 and the first backlight source 12 according to the size of the bottle embryo 6. Specifically, the locking can be achieved by fasteners such as screws and bolts.

[0041] Further, such as Figure 2 The stain detection component 2 also includes a second mounting frame 25, and the first shooting unit 21, the backlight source 1 22, the second shooting unit 23 and the backlight source 2 24 are all connected to the second mounting frame 25, and the second mounting frame 25 is used to carry the first shooting unit 21, the backlight source 1 22, the second shooting unit 23 and the backlight source 2 24.

[0042] Further, such as Figure 2 The first shooting unit 21, the backlight source 1 22, the second shooting unit 23 and the backlight source 2 24 are all movably locked and connected to the second mounting frame 25. The movably locked connection facilitates the first shooting unit 21, the backlight source 1 22, the second shooting unit 23 and the backlight source 2 24 to adjust the height according to the size of the bottle embryo 6. Specifically, the locking can be achieved by fasteners such as screws and bolts.

[0043] Further, such as Figure 2 The first shooting unit 21 includes a camera 1 211 and a camera 2 212 located on the same side, and the camera 1 211 and the camera 2 212 are located on different sides from the backlight source 1 22; the second shooting unit 23 includes a camera 3 231 and a camera 4 232 located on the same side, and the camera 3 231 and the camera 4 232 are located on different sides from the backlight source 2 24. The camera 1 211, the camera 2 212, the camera 3 231 and the camera 4 232 are all connected to the controller, and the camera 1 211, the camera 2 212, the camera 3 231 and the camera 4 232 are used for shooting, so as to make the shooting comprehensive and prevent missed detection.

[0044] Further, such as Figure 2 The camera 1 211 and the camera 2 212 are located on the same vertical line, and the camera 3 231 and the camera 4 232 are located on the same vertical line. Being located on the same vertical line facilitates the camera 1 211 and the camera 2 212 to be used for photographing the upper and lower positions on one side of the bottle embryo 6, and facilitates the camera 3 231 and the camera 4 232 to be used for photographing the upper and lower positions on the other side of the bottle embryo 6.

[0045] Further, such as Figure 2 The camera 1 211 and the camera 2 212 are perpendicular to each other as are the camera 3 231 and the camera 4 232. The backlight source 1 22 and the backlight source 2 24 are perpendicular to each other. The perpendicularity facilitates dual-angle shooting of the preform 6, thereby making the shooting comprehensive and preventing missed inspections.

[0046] The present embodiment also provides a bottle blowing machine, including a bottle embryo detection device of the present embodiment, and also including: a rejection component 3; a bottle blowing component 4; a conveying component 5 that penetrates the mandrel head detection component 1, the stain detection component 2, the rejection component 3 and the bottle blowing component 4; wherein the mandrel head detection component 1, the stain detection component 2, the bottle blowing component 4 and the rejection component 3 are arranged in sequence along the conveying direction of the conveying component 5, the rejection component 3 and the conveying component 5 are both connected to the controller, the first camera 11 and the first backlight source 12 are located on different sides of the conveying component 5, the first shooting unit 21 and the backlight source 1 22 are located on different sides of the conveying component 5, and the second shooting unit 23 and the backlight source 2 24 are located on different sides of the conveying component 5.

[0047] Specifically, the rejection component 3 is used to receive the rejection signal from the controller and to reject the problematic preform 6; the bottle blowing component 4 is used to process the preform 6 into a bottle; the conveying component 5 is used to convey the preform 6 and the bottle, and the conveying component 5 includes an encoder connected to the controller, and the encoder is used to transmit the conveying position signal of the conveying component 5 to the controller, so that the controller can control the rejection component 3 to accurately reject the problematic preform 6.

[0048] Further, such as Figure 3 The rejecting assembly 3 includes: a driving cylinder 31; and a rejecting head 32 connected to the driving shaft of the driving cylinder 31; wherein the driving cylinder 31 is connected to the controller via a solenoid valve 33.

[0049] Specifically, the controller controls the electromagnetic valve 33 , the electromagnetic valve 33 controls the driving cylinder 31 , and the driving cylinder 31 controls the rejecting head 32 to reject the problematic preform 6 .
