Description

Technical Field

[0001] This utility model relates to the field of bottle testing equipment technology, and in particular to a bottle testing device. Background Technology

[0002] Bottle inspection devices are machines used to check whether recycled or newly manufactured bottles are damaged or contain impurities. Currently, after prolonged operation, the inspection accuracy of these devices may decrease due to broken glass or dust obstructing the inspection lens. Therefore, the devices need to be calibrated periodically. This involves manually placing defective bottles into the device, inspecting them, and then manually removing them. Finally, the inspection accuracy is determined by analyzing the data from the device's human-machine interface. However, this manual bottle placement and removal method is labor-intensive and inefficient. Utility Model Content

[0005] The bottle conveying assembly includes a main conveyor line and a sample bottle conveyor line, wherein both ends of the sample bottle conveyor line are connected to the main conveyor line, and sample bottles are provided on the sample bottle conveyor line;

[0006] A bottle sorting assembly, located on the main conveyor line, is used to sort bottles that enter the main conveyor line.

[0007] A bottle inspection machine is installed on the main conveyor line and is used to inspect the bottles after they have been sorted by the bottle sorting assembly.

[0008] A lane-changing assembly includes at least two lane changers located at the intersection of the sample bottle conveying line and the main conveying line, so as to alternately connect or block the sample bottle conveying line and the main conveying line.

[0009] During the calibration of the bottle inspection machine, the channel changer controls the sample bottle conveying line to connect with the main conveying line, so that the sample bottle enters the main conveying line, is sorted by the bottle sorting assembly, is inspected by the bottle inspection machine, and then returns to the sample bottle conveying line.

[0010] In one embodiment, the lane changer includes a bracket, a lane change plate, and a drive unit mounted on the bracket. The bracket is positioned above the bottle inlet conveyor line and the sample bottle conveyor line. One end of the lane change plate is hinged to the bracket, and the other end extends away from the bracket. The drive unit can drive the lane change plate to swing between the main conveyor line and the sample bottle conveyor line to connect or block the sample bottle conveyor line with the main conveyor line.

[0011] In one embodiment, the lane changer further includes a connecting rod and a rotating shaft, the rotating shaft passing through the bracket, one end of the rotating shaft being connected to one end of the connecting rod, and the other end of the rotating shaft being connected to the end of the lane change plate near the bracket, and the other end of the connecting rod being connected to the conveying shaft of the drive member.

[0012] In one embodiment, the output shaft of the drive member forms an angle S with the length direction of the bracket, and the angle S is 20°–30°.

[0013] In one embodiment, the bottle conveying assembly further includes an inlet conveyor line and an outlet conveyor line, one end of the inlet conveyor line being connected to the inlet end of the main conveyor line, and one end of the outlet conveyor line being connected to the outlet end of the main conveyor line.

[0014] In one embodiment, the sample bottle conveying line includes a first conveying line, a second conveying line, and a third conveying line connected in sequence. The main conveying line has a bottle inlet section and a bottle outlet section. One end of the first conveying line is connected to the bottle inlet section, and the other end of the first conveying line is connected to one end of the second conveying line. One end of the third conveying line is connected to the bottle outlet section, and the other end of the third conveying line is connected to the other end of the second conveying line.

[0015] In one embodiment, the bottle inspection device further includes a photoelectric detection element, which includes a transmitter and a receiver disposed on both sides of the third conveyor line.

[0016] In one embodiment, the bottle unloading assembly includes two bottle unloading units arranged opposite each other, the two bottle unloading units being located on both sides of the main conveyor line, and a bottle unloading channel for bottles to pass through is defined between the two bottle unloading units.

[0017] In one embodiment, the bottle unscrambling unit includes a drive motor, a belt, and two drive wheels, the two drive wheels being spaced apart, the belt being wound between the two drive wheels, and the output shaft of the drive motor being connected to one of the two drive wheels.

[0018] In one embodiment, guardrails are provided on both sides of the main conveyor line and the sample bottle conveyor line.

[0019] The technical solutions provided in this application have the following advantages compared with the prior art:

[0020] By installing a switcher at the intersection of the sample bottle conveyor line and the main conveyor line, the connection or blockage between the two lines can be controlled. When the bottle inspection machine needs to be calibrated again, the switcher switches to the position where the sample bottle conveyor line is connected to the main conveyor line. At this time, the sample bottles on the sample bottle conveyor line automatically enter the main conveyor line, are sorted by the bottle management assembly, and then enter the bottle inspection machine for inspection. The inspection results are then compared with the defects on the sample bottles to determine the inspection capability of the bottle inspection machine. After inspection, the sample bottles return from the main conveyor line to the sample bottle conveyor line for subsequent use of the bottle inspection machine. In other words, compared with the traditional method of manually placing sample bottles for calibration, this bottle inspection device can automatically pick up and place bottles, eliminating the need for manual operation, effectively reducing labor intensity, and improving the efficiency of bottle handling.

[0033] Please refer to Figure 1 and Figure 2 This application provides a bottle inspection device, which includes a bottle conveying assembly, a bottle sorting assembly 20, a bottle inspection machine 30, and a switching assembly. The bottle conveying assembly includes a main conveyor line 11 and a sample bottle conveyor line 12. Both ends of the sample bottle conveyor line 12 are connected to the main conveyor line 11, and sample bottles 50, which are defective bottles, are placed on the sample bottle conveyor line 12. After the bottle inspection machine 30 has been running for a period of time, the sample bottles 50 enter the main conveyor line 11 and are passed into the bottle inspection machine 30 for inspection. Then, by comparing the inspection results with the defects of the sample bottles 50, it is determined whether the inspection capability of the bottle inspection machine 30 has decreased, so that the quality inspector can adjust the inspection parameters of the bottle inspection machine 30 in a timely manner to prevent unqualified bottles from flowing into the next process. The bottle sorting assembly 20 is located on the main conveyor line 11 and is used to sort the bottles entering the main conveyor line 11. It should be noted that the bottles sorted by the bottle sorting assembly 20 include the sample bottles 50 and the bottles to be inspected. The term "bottle sorting" here refers to separating adjacent bottles by a distance to achieve bottle separation. The bottle inspection machine 30 is located on the main conveyor line 11, behind the bottle sorting assembly 20, and is used to inspect individual bottles after sorting. The lane changing assembly includes at least two lane changers 40, which are located at the intersection of the sample bottle conveyor line 12 and the main conveyor line 11, allowing for alternating connection or blockage between them.

[0034] During the calibration of the bottle inspection machine 30, the switcher 40 connects the sample bottle conveyor line 12 to the main conveyor line 11, allowing the sample bottle 50 to enter the inlet conveyor line 13. After being sorted by the bottle management assembly 20, the sample bottle 50 is inspected by the bottle inspection machine 30 and then returns to the sample bottle conveyor line 12. During normal bottle inspection, the switcher 40 disconnects the sample bottle conveyor line 12 from the main conveyor line 11. In this case, the sample bottle 50 on the sample bottle conveyor line 12 will not enter the main conveyor line 11; only the bottles to be inspected enter the main conveyor line 11, are sorted by the bottle management assembly 20, and then enter the bottle inspection machine 30 for inspection.

[0035] For example, the channel changer 40 serves to control the connection or blockage between the sample bottle conveyor line 12 and the main conveyor line 11, depending on whether the bottle inspection machine 30 in the bottle inspection device needs to be calibrated. That is, when the calibration function is not activated, the channel changer 40 blocks the sample bottle conveyor line 12, so that the sample bottle conveyor line 12 and the main conveyor line 11 are in a blocked state. At this time, the bottle to be inspected is fed into the main conveyor line 11, and after being calibrated by the bottle sorting assembly 20, it enters the bottle inspection machine 30 for inspection, and finally exits from the other end of the main conveyor line 11 to complete the bottle inspection. When the bottle inspection device has been running for a period of time and the bottle inspection machine 30 needs to be inspected, the calibration function is activated, causing the channel changer 40 to connect or block the sample bottle conveyor line 12. The bottle inlet end of the main conveyor line 11 is sealed. At this time, the sample bottle conveyor line 12 is connected to the main conveyor line 11. Under the action of the sample bottle conveyor line 12, the sample bottles 50 enter the main conveyor line 11 in sequence. After the bottle sorting assembly 20 sorts the bottles, the individual bottles enter the bottle inspection machine 30 for inspection in sequence. Finally, by comparing the test results with the defects of the sample bottles 50, it is determined whether the inspection capability of the bottle inspection machine 30 has decreased. This allows the quality inspector to adjust the test parameters of the bottle inspection machine 30 in a timely manner to prevent unqualified bottles from flowing into the next process.

[0036] In summary, the bottle inspection device of this embodiment uses a switcher 40 at the intersection of the sample bottle conveyor line 12 and the main conveyor line 11 to control the connection or blockage between them. When the bottle inspection machine 30 needs to be calibrated again, the switcher 40 switches to the position where the sample bottle conveyor line 12 and the main conveyor line 11 are connected. At this time, the sample bottles 50 on the sample bottle conveyor line 12 automatically enter the main conveyor line 11, are sorted by the bottle management assembly 20, and then enter the bottle inspection machine 30 for inspection. The inspection capability of the bottle inspection machine 30 is determined by comparing the inspection results with the defects on the sample bottles 50. After inspection, the sample bottles 50 return from the main conveyor line 11 to the sample bottle conveyor line 12 for subsequent use of the bottle inspection machine 30. In other words, compared with the traditional method of manually placing sample bottles 50 for calibration, this bottle inspection device can automatically pick up and place bottles, eliminating the need for manual operation, effectively reducing labor intensity and improving the efficiency of bottle handling.

[0037] For example, the bottle inspection machine 30 serves to inspect the bottles to prevent unqualified bottles from flowing into the next process. Therefore, the bottle inspection machine 30 can employ existing equipment commonly used for bottle inspection, which will not be elaborated upon here.

[0038] It should be noted that the switcher 40 can be a component in the prior art that can switch between connecting and blocking the sample bottle conveying line 12 and the main conveying line 11, or it can be the specific structure used in the following embodiments, which is not limited.

[0039] Reference Figure 3 Specifically, the lane changer 40 includes a bracket 41, a lane change plate 42, and a drive unit 43 mounted on the bracket 41. The bracket 41 spans over the bottle inlet conveyor line 13 and the sample bottle conveyor line 12. One end of the lane change plate 42 is hinged to the bracket 41, and the other end extends away from the bracket 41. The drive unit 43 can drive the lane change plate 42 to swing between the main conveyor line 11 and the sample bottle conveyor line 12, so that the sample bottle conveyor line 12 can connect with or block the main conveyor line 11.

[0040] In practical applications, when the bottle inspection machine 30 does not require calibration, the drive unit 43 drives the switching plate 42 to swing between the main conveyor line 11 and the sample bottle conveyor line 12, so that the switching plate 42 switches to block the port of the sample bottle conveyor line 12 (see reference). Figure 1 At this time, the bottles to be inspected are fed into the main conveyor line 11. Then, under the action of the bottle sorting assembly 20, the individual bottles are spaced apart and enter the bottle inspection machine 30 for inspection in sequence, thus ensuring normal inspection of the bottles. When the bottle inspection machine 30 needs to be calibrated, the drive unit 43 drives the changing plate 42 to swing from the port of the sample bottle conveyor line 12 toward the main conveyor line 11, so that the changing plate 42 switches to the port of the main conveyor line 11 for sealing. At this time, the sample bottle conveyor line 12 is connected to the main conveyor line 11 (refer to...). Figure 2 Afterwards, the sample bottles 50 located on the sample bottle conveyor line 12 enter the main conveyor line 11, and then, under the action of the bottle sorting assembly 20, they are formed into spaced individual bottles that sequentially enter the bottle inspection machine 30 for inspection. Finally, the inspection capability of the bottle inspection machine 30 is determined by comparing the inspection results with the defects on the sample bottles 50. In addition, the sample bottles 50 inspected by the bottle inspection machine 30 will return from the main conveyor line 11 to the sample bottle conveyor line 12, so that the bottle inspection machine 30 can be used again later without the need for manual placement of new sample bottles 50 on the sample bottle conveyor line 12.

[0041] In addition, the drive unit 43 can be driven by a cylinder or by a power component that can drive the lane change plate 42 for switching, and there is no limitation on the latter.

[0042] Reference Figure 3In one embodiment, the lane changer 40 further includes a connecting rod 44 and a rotating shaft 45. The rotating shaft 45 passes through the bracket 41, with one end of the rotating shaft 45 connected to one end of the connecting rod 44, and the other end of the rotating shaft 45 connected to the end of the lane change plate 42 near the bracket 41. The other end of the connecting rod 44 is connected to the conveying shaft of the drive member 43. That is, by using the rotating shaft 45 to pass through the bracket 41, and then connecting the end of the lane change plate 42 near the bracket 41 and the end of the connecting rod to both ends of the rotating shaft 45, and by using the output shaft of the drive member 43 to connect to the other end of the connecting rod, the lane change plate 42 can be connected to the drive member 43. This ensures that when the drive member 43 determines that the connecting rod 44 is rotating, the lane change plate 42 can be driven to swing between the main conveyor line 11 and the sample bottle conveyor line 12, thereby controlling the connection or blockage between the main conveyor line 11 and the sample bottle conveyor line 12.

[0043] In one embodiment, the output shaft of the drive member 43 forms an angle S with the length direction of the bracket 41, where the angle S is 20°–30°. That is, the drive member 43 is mounted on the bracket 41 in an inclined manner to make full use of space, avoid the component interference problems caused by traditional vertical installation, and reduce energy loss during transmission.

[0044] In one embodiment, the bottle conveying assembly further includes an inlet conveyor line 13 and an outlet conveyor line 14. One end of the inlet conveyor line 13 is connected to the inlet end of the main conveyor line 11, and one end of the outlet conveyor line 14 is connected to the outlet end of the main conveyor line 11. That is, when the bottle to be tested is being tested, the guide plate 42 blocks the port of the sample bottle conveyor line 12. At this time, both the inlet conveyor line 13 and the outlet conveyor line 14 are connected to the main conveyor line 11. The bottle to be tested enters the main conveyor line 11 under the action of the inlet conveyor line 13, and then passes through the bottle sorting assembly 20 and the bottle inspection machine 30 in sequence. Finally, the inspected bottle is conveyed to the placement position for storage via the outlet conveyor line 14. When the verification function is activated, the switching plate 42 blocks the port of the main conveyor line 11. At this time, the bottle inlet conveyor line 13 and the bottle outlet conveyor line 14 are not connected to the main conveyor line 11. Only the sample bottle conveyor line 12 is connected to the main conveyor line 11 to form a circular conveying path, so that the inspected bottle will return to the sample bottle conveyor line 12, ensuring that the sample bottle 50 can be used again.

[0045] In one embodiment, the sample bottle conveying line 12 includes a first conveying line 121, a second conveying line 122, and a third conveying line 123 connected in sequence. The main conveying line 11 has a bottle inlet section 11a and a bottle outlet section 11b. One end of the first conveying line 121 is connected to the bottle inlet section 11a, and the other end of the first conveying line 121 is connected to one end of the second conveying line 122. One end of the third conveying line 123 is connected to the bottle outlet section 11b, and the other end of the third conveying line 123 is connected to the other end of the second conveying line 122. Furthermore, the bottle inspection device also includes a photoelectric detection element 60, which includes a transmitter 61 and a receiver 62 respectively disposed on both sides of the third conveying line 123. The transmitter 61 and the receiver 62 cooperate to detect the number of sample bottles 50 passing through.

[0046] In practical applications, multiple sample bottles 50 are arranged side-by-side on the first conveyor line 121. When the verification function is activated, the first conveyor line 121 starts to sequentially feed the sample bottles 50 onto the main conveyor line 11. The bottle sorting assembly 20 then sorts the side-by-side sample bottles 50, separating adjacent bottles by a distance. Each sample bottle 50 then sequentially enters the bottle inspection machine 30 for inspection. After inspection, the sample bottles 50 move from the main conveyor line 11 to the third conveyor line 123 and are then detected by the transmitter 61. In conjunction with the receiver 62, the number of sample bottles 50 passing through is counted. At this time, the second conveyor line 122 is not started. The inspected sample bottles 50 are located on the second conveyor line 122. After the number of sample bottles 50 entering the main conveyor line 11 is counted, it indicates that the verification of the bottle inspection machine 30 is completed. At this time, the switch plate 42 switches to the position of blocking the port of the first conveyor line 121 and starts the second conveyor line 122 to transport the sample bottles 50 to the first conveyor line 121 to ensure that the sample bottles 50 can be used again.

[0047] Reference Figure 4 In one embodiment, the bottle-sorting assembly 20 includes two bottle-sorting units 21 arranged opposite each other on both sides of the main conveyor line 11, with a bottle-sorting channel defined between the two bottle-sorting units 21 for the bottles to pass through. Thus, by symmetrically distributing the two bottle-sorting units 21 on both sides of the main conveyor line 11, a stable bottle-sorting channel is formed. Then, a balanced clamping or pushing force is provided by bidirectional synchronous drive, ensuring that the bottles run centered within the channel, reducing the risk of deviation or tipping, and improving bottle-sorting efficiency and stability.

[0048] Specifically, the bottle sorting unit 21 includes a drive motor 212, a belt 213, and two drive wheels 211. The two drive wheels 211 are spaced apart, and the belt 213 is wound between the two drive wheels 211. The output shaft of the drive motor 212 is connected to one of the two drive wheels 211. That is, when separating adjacent bottles, the drive motor 212 drives one of the two drive wheels 211 to rotate. Since the belt 213 is connected between the two drive wheels 211 and the belt 213 is in contact with the bottle body, the belt 213 drives the bottle to accelerate forward, thereby separating adjacent bottles by a distance, which facilitates subsequent inspection and comprehensive testing of the bottles.

[0049] In one embodiment, guardrails 70 are provided on both sides of the main conveyor line 11 and the sample bottle conveyor line 12. In this way, the symmetrical arrangement of the guardrails 70 forms a physical barrier, effectively preventing the bottles from slipping off the sides of the conveyor line due to vibration, collision or inertia during high-speed conveying, thereby reducing bottle breakage.

[0050] In addition, it should be noted that the bottle inlet conveyor line 13, bottle outlet conveyor line 14, first conveyor line 121, second conveyor line 122 and third conveyor line 123 in the embodiments of this application all adopt a combination of servo motor and conveyor belt. The technical solution of how to use servo motor to drive the conveyor belt is common knowledge to those skilled in the art, and will not be described in detail.

[0051] It is understood that the above embodiments only illustrate preferred embodiments of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present utility model patent. It should be noted that for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present utility model, all of which fall within the protection scope of the present utility model. Therefore, all equivalent transformations and modifications made within the scope of the claims of the present utility model should fall within the coverage of the claims of the present utility model.
