Description

Technical Field

[0001] This utility model relates to the field of rejection equipment technology, specifically a rejection mechanism for star wheel conveying. Background Technology

[0002] At one stage of the automated production line, an empty bottle inspection machine checks each passing bottle. If a bottle lacks a cork, a rejector quickly removes it from the production line. This step is crucial for ensuring product quality because allowing bottles without corks to proceed to the next process could cause problems in subsequent operations and even affect the quality and safety of the final product.

[0003] Currently, in existing technologies, the removal of empty bottles is generally accomplished by directly pushing the bottles with a cylinder. However, due to the frequent use of the removal operation, the cylinder seals and piston rod may wear out quickly under high load or long-term operation conditions, affecting stability. Furthermore, the exposed power source is unsightly. Therefore, a removal mechanism for star wheel conveyors is proposed. Utility Model Content

[0004] The main objective of this invention is to provide a rejection mechanism for star wheel conveying, which can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention proposes a rejection mechanism for a star wheel conveyor, comprising a frame, a guide plate fixedly connected to the upper side of the frame, a stepper motor fixedly connected to the bottom of the frame, a star wheel conveyor disk fixedly connected to the output shaft of the stepper motor, a collection box fixedly connected to the outer wall of the frame, a rejection device disposed below the star wheel conveyor disk, and a bottle stopper detection photoelectric sensor fixedly connected to the upper side of the guide plate. The rejection device includes:

[0006] A fixed sleeve is fitted with a lifting shaft, which can be raised and lowered by an electric telescopic rod;

[0007] A fixed arm is fixedly connected to the outer wall of the lifting shaft. A hinge rod is hinged to the top of the fixed arm, and a pusher is hinged to the end of the hinge rod away from the fixed arm.

[0008] The fixed block is slidably connected to the pusher and is raised and lowered by the lifting shaft, which drives the fixed arm to rise and fall. Then, under the action of the hinge rod, the pusher slides on the fixed block to remove bottles without stoppers.

[0009] Preferably, the fixing block is fixedly connected to the inner surface of the frame.

[0010] Preferably, the outer wall of the guide plate has an opening, and the opening is aligned with the collection box.

[0011] Preferably, the pushing member includes a pushing rod, an elastic telescopic rod is fixedly connected to the inner wall of the pushing rod, a top block is fixedly connected to the telescopic end of the elastic telescopic rod, and the telescopic end of the elastic telescopic rod passes through a ring and is fixedly connected to the ring.

[0012] Preferably, a positioning shaft is fixedly connected to the inner wall of the push rod, and the positioning shaft passes through the L plate and is rotatably connected to the L plate.

[0013] Preferably, there are two sets of L-plates, and the two sets of L-plates are symmetrically arranged with the central axis of the elastic telescopic rod as the axis of symmetry. The top block contacts the bottle, and the bottle squeezes the top block to compress the telescopic end of the elastic telescopic rod. The ring squeezes the L-plate to move, so that the L-plate positions the two sides of the bottle and improves the stability of the bottle conveying.

[0014] This utility model provides a rejection mechanism for star wheel conveying. It has the following beneficial effects:

[0015] (1) The star wheel conveyor rejection mechanism uses a rejection device to lift and lower the lifting shaft, which drives the fixed arm to lift and lower. Then, under the action of the hinge rod, the pusher slides on the fixed block to reject bottles without stoppers. It has good stability, the power source is not exposed, and the device is aesthetically pleasing.

[0016] (2) The star wheel conveyor rejection mechanism uses a pusher to make the top block contact the bottle during the pushing process. The bottle squeezes the top block to compress the telescopic end of the elastic telescopic rod, and the ring squeezes the L plate to move, so that the L plate positions the two sides of the bottle and improves the stability of the bottle conveying.

The bottle stopper detection photoelectric sensor 6 can detect the bottle stopper. When the bottle stopper detection photoelectric sensor 6 does not detect the bottle stopper, the star wheel conveyor disk 3 continues to rotate and stops at the position corresponding to the collection box 4.

[0028] To remove bottles without stoppers, the outer wall of the guide plate 2 has an opening aligned with the collection box 4. The removal device 5 includes a fixed sleeve 51, a fixed arm 53, and a fixed block 56. The fixed sleeve 51 is fitted with a lifting shaft 52, which can be raised and lowered by an electric telescopic rod. The fixed arm 53 is fixedly connected to the outer wall of the lifting shaft 52. A hinge rod 54 is hinged to the top of the fixed arm 53, and a pusher 55 is hinged to the end of the hinge rod 54 away from the fixed arm 53. The fixed block 56 is slidably connected to the pusher 55 and is fixedly connected to the inner surface of the frame 1. The lifting shaft 52 raises and lowers, driving the fixed arm 53 to rise and fall. Under the action of the hinge rod 54, the pusher 55 slides on the fixed block 56, thus removing bottles without stoppers and pushing them into the collection box 4 to complete the removal. The device has good stability, the power source is not exposed, and the device is aesthetically pleasing.

[0029] Example 2

[0030] Based on Example 1, please refer to Figure 4 The pushing component 55 includes a pushing rod 551, an elastic telescopic rod 552 fixedly connected to the inner wall of the pushing rod 551, a top block 553 fixedly connected to the telescopic end of the elastic telescopic rod 552, the telescopic end of the elastic telescopic rod 552 passing through and fixedly connected to the ring 554, a positioning shaft 556 fixedly connected to the inner wall of the pushing rod 551, the positioning shaft 556 passing through the L plate 555 and rotatably connected to the L plate 555, two sets of L plates 555 are provided, and the two sets of L plates 555 are symmetrically arranged about the central axis of the elastic telescopic rod 552. During the pushing process, the top block 553 contacts the bottle, the bottle squeezes the top block 553 to compress the telescopic end of the elastic telescopic rod 552, causing the ring 554 to squeeze the L plate 555 to move, thereby positioning the L plate 555 on both sides of the bottle and improving the stability of the bottle conveying.

[0031] It should be noted that all the electrical components mentioned above are existing technology products. Those skilled in the art should select, install, and debug the circuits according to their needs to ensure that all electrical appliances function properly. All components are general standard parts or parts known to those skilled in the art, and their structures and principles can be obtained by those skilled in the art through technical manuals or conventional experimental methods. No specific restrictions are imposed here.

[0032] In use, the stepper motor is first started to drive the star wheel conveyor 3 to rotate. The bottle stopper detection photoelectric sensor 6 detects the bottle stopper. When the bottle stopper detection photoelectric sensor 6 does not detect the bottle stopper, the star wheel conveyor 3 continues to rotate and stops at the position corresponding to the collection box 4. Then, it is raised and lowered by the lifting shaft 52, which drives the fixed arm 53 to rise and fall. Then, under the action of the hinge rod 54, the pusher 55 slides on the fixed block 56 to remove bottles without bottle stoppers. During this process, the top block 553 contacts the bottle, and the bottle squeezes the top block 553 to compress the telescopic end of the elastic telescopic rod 552, causing the ring 554 to squeeze the L plate 555 to move, thereby positioning the L plate 555 on both sides of the bottle.
