Abstract
Description
Technical Field
[0001] This utility model relates to the field of injection blow molding machine technology, specifically to a bottle rejection device in an injection blow molding machine production line. Background Technology
[0002] Injection blow molding machines can be used for injection and blow molding of plastic products. Most existing injection molding machines have a turret structure. Each time the injection mold and blow mold open and close, the turret rotates one station. Injection, blow molding, and unloading are performed on three sides of the turret, and the cyclical synchronous operation improves the working efficiency of the device. Three-station injection blow molding machines are often used in the production of plastic packaging bottles. In order to achieve fast unloading, the packaging bottles may not be able to be placed vertically, stably, and accurately on the conveyor belt during the unloading process, resulting in bottles tipping over. This requires workers to sort them out and is inconvenient for transfer. Utility Model Content
[0003] In order to overcome the above-mentioned defects in the prior art, this utility model provides a bottle rejection device for injection blow molding production line.
[0004] A bottle-removing device for an injection blow molding machine production line includes a conveyor belt located on the feeding side of the injection blow molding machine. A bottle-removing mechanism and a bottle-collecting mechanism are respectively provided on both sides of the conveyor belt. The bottle-removing mechanism includes a pusher frame for pushing the bottle away from the conveyor belt, and the bottle-collecting mechanism includes a collection cylinder for collecting the bottles that have fallen off the conveyor belt.
[0005] Furthermore, a separation box is provided below the collection cylinder, and a conveyor belt is provided inside the separation box. Baffles are provided on the conveyor belt, and an inverted bottle can be accommodated between adjacent baffles. A visual detector is provided on the side wall of the separation box, and the visual detector is used to detect the position of the neck of the inverted bottle.
[0006] Furthermore, the separation box is equipped with two sets of bottle straightening components. Each bottle straightening component includes a pusher block, which is connected to the output end of a telescopic cylinder. The telescopic cylinder is installed on the outer wall of the mounting cylinder on the side wall of the separation box. The pusher block enters the separation box from the mounting cylinder and pushes the bottle on the conveyor belt into the straightening cylinder, where the bottle becomes vertical.
[0007] Furthermore, the two sets of bottle-righting components are staggered, and the pushing direction of the two sets of bottle-righting components and the opening direction of the top of the uprighting cylinder are opposite, so that the bottle bottom is down and the neck is up as the bottle falls along the uprighting cylinder according to the position of the bottle neck.
[0008] Furthermore, each set of the straightening cylinders is provided with a collecting plate below it. The collecting plate has annular protrusions. Packaging bottles that fall from the straightening cylinders fall onto the collecting plate, with their bottoms located within the annular protrusions.
[0009] Furthermore, a movable plate is provided below the collecting plate, the movable plate is slidably connected to the slide block, the slide block is provided with a movable lead screw, the movable plate is connected to the movable lead screw, the slide block is slidably connected to the base, the base is provided with a transmission lead screw, the transmission lead screw is connected to the slide block, and both the base and the slide block are provided with drive motors for driving the movable lead screw and the transmission lead screw to rotate.
[0010] Furthermore, the pusher includes two moving blocks, the side of which near the inverted bottle is an arc-shaped surface, and the pusher is connected to the output end of the rejection cylinder.
[0011] Furthermore, a bottle-tipping detection component is provided on one side of the conveyor belt. The bottle-tipping detection component includes a mounting plate, and sensors are provided on the top and bottom of the mounting plate.

[0021] To more clearly illustrate the technical solution of this utility model, the following description is made in conjunction with the accompanying drawings. Obviously, the drawings described below are only one embodiment of this utility model. For those skilled in the art, other embodiments can be obtained based on these drawings and embodiments without creative effort, and all of them fall within the protection scope of this utility model.
[0022] according to Figure 1-7 As shown, a bottle-removing device in an injection blow molding machine production line includes a conveyor belt 2 located on the feeding side of the injection blow molding machine 1. A bottle-removing mechanism and a bottle-collecting mechanism are respectively provided on both sides of the conveyor belt 2. The bottle-removing mechanism includes a pusher 3 that pushes the bottle away from the conveyor belt 2, and the bottle-collecting mechanism includes a collection cylinder 4 for collecting bottles that have fallen off the conveyor belt 2.
[0023] In the above specific technical solution, when a bottle is tilted, the tilted bottle is pushed into the collection cylinder 4 of the tilted bottle collection mechanism by the pusher 3 of the tilted bottle rejection mechanism. Then, after being processed by the tilted bottle collection mechanism, the tilted bottle is turned into a vertical state, and the vertically turned packaging bottles are stacked neatly, so that the staff can directly transport them to the next work station of the packaging bottle processing.
[0024] Below the collection cylinder 4 is a separation box 5, inside which is a conveyor belt 6, and on the conveyor belt 6 are baffles 7. A bottle can be accommodated between adjacent baffles 7. A visual detector 8 is provided on the side wall of the separation box 5, and the visual detector 8 is used to detect the position of the bottle neck.
[0025] The separation box 5 is equipped with two sets of bottle straightening components. Each bottle straightening component includes a pusher 9, which is connected to the output end of a telescopic cylinder 10. The telescopic cylinder 10 is installed on the outer wall of the mounting cylinder 11 on the side wall of the separation box 5. The pusher 9 enters the separation box 5 from the mounting cylinder 11 and pushes the bottle on the conveyor belt 6 into the straightening cylinder 12, where the bottle becomes vertical.
[0026] The two sets of bottle-righting components are staggered, and the direction of movement of the push block 9 of the two sets of bottle-righting components is opposite to the direction of the opening at the top of the uprighting cylinder 12. Thus, according to the position of the bottle neck, the bottle will be in a state with the bottom down and the neck up as it falls along the uprighting cylinder 12.
[0027] In the above specific technical solution, the inverted bottle falls from the collection cylinder 4 onto the conveyor belt 6 in the separation box 5. The partitions on the conveyor belt 6 divide it into multiple relatively independent spaces, each capable of holding one inverted bottle. As the conveyor belt 6 rotates, it transports the inverted bottle to the detection station. A vision detector 8 detects the neck position of the inverted bottle and determines which set of bottle-correcting components needs to operate. The inverted bottle is then transported to the corresponding working point of the bottle-correcting component via the conveyor belt 6. The telescopic cylinder 10 is activated, and the pusher 9 enters the separation box 5 from the mounting cylinder 11, pushing the inverted bottle on the conveyor belt 6 into the correcting cylinder 12. The bottle falls into the correcting cylinder 12 with the bottom down and the neck up. It is worth noting that the conveyor belt 6 transports the bottle in a direction perpendicular to the length of the bottle, while the pusher 9 moves parallel to the length of the bottle.
[0028] Each set of straightening cylinders 12 is provided with a collecting plate 13 below it. The collecting plate 13 is provided with annular protrusions 14. Packaging bottles that fall from the straightening cylinder 12 fall onto the collecting plate 13, and their bottoms are located inside the annular protrusions 14.
[0029] Below the collecting plate 13, there is a movable plate 15. The movable plate 15 is slidably connected to the slide block 16. The slide block 16 is provided with a movable lead screw 17. The movable plate 15 and the movable lead screw 17 are connected in cooperation. The slide block 16 is slidably connected to the base 18. The base 18 is provided with a transmission lead screw 19. The transmission lead screw 19 is connected in cooperation with the slide block 16. Both the base 18 and the slide block 16 are provided with drive motors that drive the movable lead screw 17 and the transmission lead screw 19 to rotate.
[0030] In the above specific technical solution, the packaging bottles falling from the straightening cylinder 12 fall onto the collecting plate 13, and the bottom of the bottle falls into the annular protrusion 14. Then, by moving the moving plate 15, the falling packaging bottles fall into the empty annular protrusion 14 in sequence. When the collecting plate 13 is full of packaging bottles, the workers can remove it from the moving plate 15, replace it with a new collecting plate 13, and then uniformly transport the full collecting plate 13 to the next working point. Preferably, the collecting plate 13 can be provided with a handle to facilitate the removal of the collecting plate 13. Furthermore, the moving plate 15 is provided with a limiting component for positioning the collecting plate 13.
[0031] The pusher 3 includes two moving blocks 20. The side of the moving block 20 closest to the bottle inverting is an arc-shaped surface 21. The pusher 3 is connected to the output end of the rejection cylinder 22. The pusher 3 pushes the inverted bottle on the conveyor belt 2 into the collection cylinder 4. It is worth noting that the pusher 3 and the corresponding conveyor frame of the collection cylinder 4 are provided with notches to facilitate pushing the inverted bottle into the collection cylinder 4.
[0032] A bottle-inverting detection component is also provided on one side of the conveyor belt 2. The bottle-inverting detection component includes a mounting plate 23. Sensors 24 are provided at the top and bottom of the mounting plate 23. When both the upper and lower sensors 24 detect or do not detect the packaging bottle, the bottle-inverting rejection mechanism and the bottle-inverting collection mechanism do not work. When only the bottom sensor 24 detects the packaging bottle, the bottle-inverting rejection mechanism and the bottle-inverting collection mechanism start to work.
[0033] The above embodiments are merely exemplary embodiments of the present utility model and are not intended to limit the present utility model. The scope of protection of the present utility model is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to the present utility model within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of the present utility model.
