The embodiment provides a beverage bottle label detection device, as shown in fig. 2, the beverage bottle label detection device comprises a support 10, the support 10 can be arranged on one side of a conveyor belt 14, an upper sensor 11, a middle sensor 12 and a lower sensor 13 are arranged on the support 10 in sequence from high to low, and the detection surfaces of the three sensors face a beverage bottle; the middle sensor 12 is adapted to detect a middle region C of the beverage bottle, and the middle sensor 12 outputs a first electrical signal after detecting the label or the bottle body; the upper sensor 11 is adapted to detect an upper area a of the beverage bottle, and the upper sensor 11 outputs a first electrical signal after detecting the label; the lower sensor 13 detects a lower region B of the beverage bottle, and the lower sensor 13 outputs a first electrical signal after detecting the label; as shown in fig. 2, the upper region a is a region from the mouth of the beverage bottle to the upper edge of the middle region C, and the lower region B is a region from the bottom of the beverage bottle to the lower edge of the middle region C. As shown in fig. 3, the first electrical signal may be a high-level electrical signal. Referring to fig. 7, the beverage bottle label detecting apparatus further comprises a controller 20, wherein a first input terminal of the controller 20 is connected to the output terminal of the upper sensor 11, a second input terminal of the controller 20 is connected to the output terminal of the middle sensor 12, and a third input terminal of the controller 20 is connected to the output terminal of the lower sensor 13; the controller 20 determines the position of the tag according to the signals output from the upper sensor 11, the middle sensor 12, and the lower sensor 13; the output of the controller 20 outputs a second electrical signal at a set time after detecting that the label position is not within the labeling area.

In the solution provided in this embodiment, as shown in fig. 2, the normal labeling areas are the lower area B and the middle area C, i.e. the area 1 is a qualified placing position, and the area 2 is a non-qualified (high-grade) placing position. As shown in fig. 3, if the signal received by the controller 20 is "110", it can be determined that the tag is attached to the upper area a, and the result is a high mark; if the signal received by the controller 20 is "011", it can be determined that the label is attached to the labeling area and the labeling result is qualified; if the signal received by the controller 20 is "010", it can be judged as no label because only the central sensor 12 having the highest sensitivity has an output signal, indicating that only a bottle body or a central area C has a label is detected, and if the signal received by the controller 20 is "000", indicating that no beverage bottle is detected at this time. Through the scheme in this application, also there is signal output when guaranteeing no mark beverage bottle to pass through, no signal output when only having no beverage bottle, can increase the testing result of no mark beverage bottle from this.

In the above solution, the upper sensor 11, the middle sensor 12 and the lower sensor 13 are all photoelectric sensors, and the first electrical signal is a high-level signal; the upper sensor 11, the middle sensor 12, and the lower sensor 13 output a low level signal when the label or the bottle is not detected. The photoelectric sensor can be provided with a transmitter for transmitting laser and a receiver for receiving reflected laser, the receiver can obtain an electric signal corresponding to the intensity of the reflected laser after receiving the reflected laser, and whether the reflected laser is reflected by the label can be judged according to the amplitude of the electric signal. If the laser is irradiated on the bottle body, the intensity of the reflected laser is very small, and if the laser is irradiated on the label, the intensity of the laser emitted by the label is relatively large. According to the principle, in order to comprehensively detect the bottle body of the beverage bottle, the number of the upper sensors, the number of the middle sensors and the number of the lower sensors can be set to be multiple, so that the detected area of the bottle body is covered.

In some embodiments, the three sensors may be general sensors for detecting the bottle label in the prior art, such as a camera, an image captured by the camera is processed by an image processor inside the camera to determine whether the label is a set label, and if the label is identified by the image processor, the image processor may directly output the first electrical signal. Assuming that the middle area C is a labeling area, as shown in fig. 4, after the controller 20 receives the detection signals sent by the three sensors, the label position can be determined only by simple signal comparison. If the signal received by the controller 20 is "110", it can be determined that the label is attached to the upper region, if the signal received by the controller 20 is "011", it can be determined that the label is attached to the lower region, if the signal received by the controller 20 is "010", it can be determined that the label is attached to the label applying region, and if the signal received by the controller 20 is "000", it is determined that there is no label. The data acquisition and comparison method is a common function of the units with the data processing function, such as the PLC control module, and the like, is simple and easy to realize, and has high fault tolerance rate.

In some embodiments, as shown in fig. 5, the stand 10 includes a cross bar 101 and a vertical bar 102 vertically connected to the cross bar 101, the upper sensor 11, the middle sensor 12 and the lower sensor 13 are disposed on the vertical bar 102; the cross bar 101 is fixed on the side wall of the beverage bottle conveying belt. As shown in fig. 5, a plurality of threaded holes 104 may be provided on the cross bar 101, and the cross bar 101 may be fixed to the side wall of the conveyor belt by means of bolt positioning. Further, a reinforcing rib 103 is arranged at the position where the vertical rod 102 is connected with the cross rod 101. The reinforcing ribs 103 can ensure the connection stability of the vertical rod 102. In addition, in order to reduce the influence of vibration on the rack 10, a vibration damping spacer may be provided between the crossbar 101 and the side wall of the conveyor belt. It will be understood that the conveyor belt itself is arranged on a guide rail having a metal frame, in which case the fixing of the carrier to the side walls of the conveyor belt means that the carrier is fixed to the metal frame.

As mentioned above, the output end of the controller 20 outputs the second electrical signal at the set time after detecting that the label position is not in the labeling area, wherein the set time is the time required for the unqualified beverage bottle to move from the sensor mounting position to the cylinder mounting position, so that after the sensor detects the unqualified beverage bottle labeled with the label, the cylinder is not controlled to act, the cylinder is controlled to act after the unqualified beverage bottle labeled with the label is conveyed to the cylinder mounting position, and the unqualified beverage bottle labeled with the label can be pushed away from the conveying belt after the cylinder acts, so that the beverage bottle falls into the recycling box 41. In order to adapt to bottle rejecting time of beverage bottles with different specifications, the diameter D of the beverage bottle can be stored in the controller in advance, the time delta t required for passing through one beverage bottle can be obtained by detecting the pulse width in the signal through the middle sensor, and the conveying speed v of the conveying belt can be calculated by simply applying division operation. Further, when the fixed distance d between the sensor and the cylinder is known, the time t required to delay the operation of the cylinder from the detection of the defective product may be calculated as d/v, and the calculated time may be stored in the controller as the set time. Thus, the following can be realized for beverage bottles with any diameter: if the unqualified product is detected, the time for delaying bottle rejecting is calculated and counted, the electromagnetic valve is opened when the timing time is up, and the unqualified product can be just pushed away from the conveying belt by driving the air cylinder to act.

In some aspects, the case 41 may be carried by an automated guided vehicle. The automated guided vehicle is arranged at the bottom of the box body 41, the controlled end of the automated guided vehicle is connected with the output end of the controller 20, the controller 20 counts the second electric signal, a third electric signal is output to the controlled end of the automated guided vehicle after the counting value reaches a set threshold value, the third electric signal is used for driving the automated guided vehicle to move, and meanwhile the controller 20 sends a prompt signal to the upper computer.

On the other hand, the controller 20 sends an alarm signal to the upper computer for notifying an operator to handle a full box.

Preferably, in order to further improve the integration of the pneumatic bottle rejecting device, the solenoid valve 30 and the cylinder 40 may be integrated into a unitary structure. Furthermore, a box body can be arranged outside the beverage bottle label detection device, the electromagnetic valve and the air cylinder, so that the whole device only comprises a plurality of module parts in appearance, and is simple and attractive.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit the same; although the present application has been described in detail with reference to the foregoing embodiments, it should be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions in the embodiments of the present application.
