[0002] A capping machine, also known as a cap sealing machine, a capping press or a cap locking machine, is a device used for sealing the mouths of containers such as plastic bottles and glass bottles. It has functions such as automatic cap sorting, cap feeding, and automatic capping. It has the advantages of high production speed, high automation degree, and stable operation. It can be widely used in the fields of food, medicine, chemical industry, etc. After the capping of the bottles is completed, it is necessary to detect the capping qualification of the bottles. In the prior art, generally, the bottles are detected by visual inspection, and the unqualified products are removed by a pushing mechanism. However, the existing capping detection and rejection devices have the problems that the rejected unqualified bottles are not convenient to stack and need to be stacked manually, which affects the work efficiency and wastes a lot of manpower. Content of the Utility Model

[0003] Aiming at the above problems, the purpose of the utility model is to provide a capping detection and rejection device, which, while having the function of automatically removing the bottles with ineffective capping, can also automatically arrange the removed bottles, automatically transfer these bottles onto a tray, and conveniently stack the trays, greatly improving the work efficiency of transferring the bottles after rejection, simplifying the work process, and saving manpower.

[0007] As a further improvement of the above technical solution: a first support plate is installed on the top of the conveyor belt, an electric cylinder is installed on the side of the first support plate, and the end of the piston rod of the electric cylinder is connected to the first limit plate.

[0008] The beneficial effect of this improvement is that the first limiting plate is driven by the electric cylinder to adjust the spacing to adapt to bottles of different diameters, and the bottles are limited by the first limiting plate so that multiple bottles form a straight line.

[0009] To prevent bottle shifting:

The description of this part is only exemplary and explanatory, and should not have any restrictive effect on the protection scope of the present invention.

[0027] Such as Figure 1-6As shown in the figure, a capping detection and rejection device includes a combined cabinet 1. A conveyor belt 2 is installed on the top of the combined cabinet 1. A detection mechanism 6 is installed on the top of the combined cabinet 1. A second support plate 7 is installed on the top of the conveyor belt 2. A first electric push rod 8 is installed on the side of the second support plate 7. The end of the piston rod of the first electric push rod 8 is connected to a push plate 9. A rejection channel 10 is connected to the side of the conveyor belt 2. A support 11 is provided beside the combined cabinet 1. An aggregate table 12 is provided on the top of the support 11. A third support plate 13 is installed on the top of the aggregate table 12. A second electric push rod 14 is installed at the bottom of the third support plate 13. The piston rod of the second electric push rod 14 is connected to a fourth support plate 15. A third electric push rod 16 is installed on the side of the fourth support plate 15. The piston rod of the third electric push rod 16 is connected to a U-shaped frame 17. An automatic stacking device 18 is provided on the side of the combined cabinet 1. The automatic stacking device 18 includes an outer frame 19 of the stacking mechanism. A first motor 20 is installed inside the outer frame 19 of the stacking mechanism. The output shaft of the first motor 20 is connected to a lead screw 21. The lead screw 21 is threadedly connected to a supporting block 22. A tray is placed on the top of the supporting block 22.

[0028] While this device has the function of automatically rejecting bottles with ineffective capping, it can also automatically arrange the rejected bottles, automatically transfer these bottles onto a tray 23, and conveniently stack the tray 23, greatly improving the working efficiency of transferring bottles after rejection, simplifying the working process, and saving manpower.

[0029] A first support plate 3 is installed on the top of the conveyor belt 2. An electric cylinder 4 is installed on the side of the first support plate 3. The end of the piston rod of the electric cylinder 4 is connected to a first limiting plate 5.

[0030] The distance is adjusted by driving the first limiting plate 5 with the electric cylinder 4 to adapt to bottles of different diameters. The bottles are limited by the first limiting plate 5 to form a straight line.

[0031] One side surface of the push plate 9 is an inwardly concave arc surface.

[0032] One side surface of the push plate 9 is an inwardly concave arc surface, which can prevent the bottles from shifting when pushing the bottles.

[0033] An elastic band 24 is connected to the inner wall of one side of the tray 23. A hook 26 is provided on the inner wall of the other side of the tray 23. One end of the elastic band 24 is connected to a hanging ring 25.

[0034] Connecting the hanging ring 25 at one end of the elastic band 24 to the hook 26 can prevent the bottles from slipping off the tray 23.

[0035] A motor mounting seat 27 is provided on the side of the stacking mechanism outer frame 19 , and a second motor 28 is installed on the top of the motor mounting seat 27 . The output shaft of the second motor 28 is connected to a second limiting plate 29 .

[0036] The second limiting plate 29 is used to limit the tray 23 to prevent it from sliding due to friction as the bottles are pushed in. The second motor 28 drives the second limiting plate 29 to rotate to release the limitation on the tray 23.

[0037] Working principle and usage process of the utility model: When this device is in use, the bottles to be detected are conveyed from one end of the conveyor belt 2 towards the detection mechanism 6 through the conveyor belt 2. The first limiting plate 5 plays a role in limiting the bottles so that multiple bottles form a straight line. When the bottles move between the two groups of detection mechanisms 6, the visual cameras on the two groups of detection mechanisms 6 automatically detect whether the caps on the bottles are screwed in place. The detected bottles continue to be conveyed by the conveyor belt 2. The qualified bottles continue to be conveyed directly after passing in front of the push plate 9. When the unqualified bottles move in front of the push plate 9, the first electric push rod 8 drives the push plate 9 to move towards the bottles, pushing the bottles into the inside of the waste removal channel 10. As the unqualified bottles are successively pushed in, the bottles inside the waste removal channel 10 gradually slide to the inside of the C-shaped frame 17. When there is no space inside the C-shaped frame 17 to accommodate new bottles, the third electric push rod 16 pushes the C-shaped frame 17 to move a distance equal to the diameter of one bottle. Subsequently, the second electric push rod 14 can be controlled to push the fourth support plate 15 together with the third electric push rod 16 and the C-shaped frame 17 to rise. Then, the third electric push rod 16 is controlled to drive the C-shaped frame 17 to reset, and then the second electric push rod 14 is controlled to drive the fourth support plate 15 to descend, preparing to receive the next group of bottles. When the inside of the C-shaped frame 17 is filled with bottles again, the left side of the bottle box can be transferred again, driving the previous group of bottles to move leftward. As this process is continuously repeated, the bottles in the aggregate table 12 are gradually pushed into the inside of the tray 23. When a tray 23 is filled with bottles, the first motor 20 can be controlled to operate to drive the supporting block 22 to descend. Subsequently, a new tray 23 can be placed above the tray 23 filled with bottles. Due to the setting of the second limiting plate 29, the tray 23 will not be pushed out. As the number of trays 23 increases, the cart used to carry the trays 23 can be pushed under the trays 23 to承接 the trays 23. After the cart承接s the trays 23, the second motor 28 is controlled to operate to drive the second limiting plate 29 to rotate to release the limit on the trays 23, and then the cart can be pulled out. Connecting the hanging ring 25 at one end of the elastic band 24 to the hook 26 can play a role in preventing the bottles from slipping off the tray 23. To sum up, while this device has the function of automatically removing the bottles with ineffective screw caps, it can also automatically arrange the removed bottles, automatically transfer these bottles onto the tray 23, and conveniently stack the trays 23, greatly improving the working efficiency of transferring the bottles after waste removal, simplifying the working process, and saving manpower.
