Description

Technical Field

[0001] The utility model belongs to the technical field of plastic bottle detection, and more specifically, particularly relates to a rejection device for an integrated blow molding, filling and sealing machine for plastic bottles. Background Art

[0002] The integrated blow molding, filling and sealing machine for pharmaceutical plastic bottles is a highly automated device that combines three main steps: blow molding, filling, and sealing. It is mainly used for the aseptic packaging of plastic containers in the pharmaceutical industry. After the medicine is filled and sealed in the plastic bottle, there may be some unqualified products, such as deformation, damage, contamination, or insufficient filling volume, etc. It is necessary to detect and reject defective products. The existing plastic bottle detection and rejection device generally consists of a conveyor belt, a vision scanning mechanism with devices such as a vision camera, a driving cylinder that pushes the defective product out of the conveyor belt after detecting the defective product, and a collection box for collecting the defective products.

[0003] Based on the above, although the vision scanning mechanism has the advanced function of accurately identifying the problems of defective products and instantaneously recording images, however, after the defective products are pushed into the collection box by the driving cylinder, there are often situations where multiple defective products are stacked and mixed. This phenomenon forces the staff to compare multiple defective products one by one according to the images stored in the vision scanning mechanism when conducting manual detailed analysis of the defective products later, significantly reducing the analysis efficiency and increasing the risk of errors.

This phenomenon forces the staff to compare multiple defective products one by one according to the images stored in the vision scanning mechanism when conducting manual detailed analysis of the defective products later, significantly reducing the analysis efficiency and increasing the risk of errors.

[0005] The purpose and effect of the rejection device for an integrated blow molding, filling and sealing machine for plastic bottles of the utility model are achieved by the following specific technical means:

Rotating the handwheel drives the transmission lead screw, so that the second transmission rack drives the cover plate to reset, ensuring that each cover plate returns to its initial state, preparing for the next batch of detections and improving the convenience of the reset operation of the collection box.

[0039] The present utility model works in cooperation with the separation and collection component and the driving cylinder to independently collect the removed defective plastic bottles in the collection box in sequence, avoiding the occurrence of stacking phenomena, facilitating the subsequent rapid positioning and analysis, improving the efficiency and accuracy. After the detection is completed, the handwheel drives the reset mechanism, so that the collection box and multiple cover plates quickly return to the initial state, seamlessly connecting to a new round of detections, demonstrating an efficient and convenient collection and reset process, and optimizing the overall detection and removal operation.

[0062] The first transmission gear 4, the first transmission gear 4 is rotatably connected to the bottom of the fixed box 5, the first transmission gear 4 meshes with the first transmission rack 303, and the function is that the piston rod of the driving cylinder 3 drives the push plate 301 to move backward, pushing the defective plastic bottles towards the collection box 2, and the blocking plate 201 can ensure that the plastic bottles fall into the collection box 2. During this process, when the first transmission gear 4 meshes with the first transmission rack 303, the first transmission gear 4 will rotate.

[0063] Among them, the separation and collection assembly also includes:

[0064] The transmission ratchet 401, the transmission ratchet 401 is coaxially and fixedly connected to the first transmission gear 4 above;

[0065] The transmission lead screw 6, the transmission lead screw 6 is rotatably connected inside the fixed box 5;

[0066] The transmission pawl 601, the transmission pawl 601 is coaxially and fixedly connected to the bottom of the transmission lead screw 6, the transmission pawl 601 meshes with the transmission ratchet 401, and the function is that under the action of the ratchet and pawl transmission mechanism jointly formed by the meshing of the transmission pawl 601 and the transmission ratchet 401, when the first transmission rack 303 moves backward to drive the first transmission gear 4 to rotate, the transmission pawl 601 and the transmission lead screw 6 will not rotate. When the piston rod of the driving cylinder 3 retracts, the first transmission gear 4 rotates in the reverse direction to drive the transmission lead screw 6 to rotate.

[0067] Among them, the separation and collection assembly also includes:

[0068] The connecting slider 7, the connecting slider 7 is slidably connected inside the fixed box 5, and the connecting slider 7 is threadedly connected to the transmission lead screw 6;

[0076] The specific usage mode and function of this embodiment:

[0077] After the visual scanning mechanism 101 detects a defective plastic bottle, it sends a signal to the driving cylinder 3. The piston rod of the driving cylinder 3 drives the push plate 301 to move backward, pushing the defective plastic bottle towards the collection box 2. The blocking plate 201 can ensure that the plastic bottle falls into the interior of the collection box 2; during this process, when the first transmission gear 4 meshes with the first transmission rack 303, the first transmission gear 4 will rotate. Under the action of the ratchet and pawl transmission mechanism formed by the engagement of the transmission pawl 601 and the transmission ratchet 401, the transmission pawl 601 and the transmission lead screw 6 will not rotate. When the piston rod of the driving cylinder 3 retracts, the first transmission gear 4 rotates in the reverse direction to drive the transmission lead screw 6 to rotate. The rotation of the transmission lead screw 6 drives the second transmission rack 701 to move upward through the thread transmission mechanism formed with the connecting slider 7. When the second transmission rack 701 moves upward to mesh with a second transmission gear 801, it drives the corresponding connecting shaft 8 to rotate. The rotation of the connecting shaft 8 drives the cover plate 802 to flip. The stop block 9 enables the flipped cover plate 802 to rest on it, so that the next defective plastic bottle will fall on the surface of the flipped cover plate 802, enabling multiple defective plastic bottles to fall on the surfaces of multiple cover plates 802 in sequence; this facilitates quickly finding the corresponding defective products for inspection and problem analysis according to the defective product rejection sequence recorded by the visual scanning mechanism 101 later.
