Description

Technical Field

[0001] The present invention relates to the technical field of contact lens PP cup collection, and specifically to a contact lens PP cup collector and its collection and palletizing methods. Background Art

[0002] Contact lens PP cups are cups made of polypropylene (PP) material, which are specifically used for contact lens care. The PP material is a non-toxic, odorless, and high-temperature resistant plastic, with good chemical stability and corrosion resistance. Therefore, it is suitable for making care products that come into direct contact with the eyes. PP cups are used to store contact lenses. When the contact lenses are not being worn, they can be placed in the PP cups to keep them clean and moist. PP cups are usually used together with contact lens care solution to soak and disinfect the contact lenses, in order to remove proteins, bacteria, and other impurities on the lenses. The PP cups are designed to be compact and easy to carry, making them suitable for use when traveling or going out.

[0003] Existing PP cups have a large amount of static electricity and dust after coming out of the injection molding machine. Operators need to wear heavy protective clothing to manually remove the PP cups from the injection molding machine, which poses a risk of being electrocuted. At the same time, after the PP cups are removed, they need to be de-electrified and dusted separately, and then manually stacked together by workers. After arranging them in several rows, they are manually bagged. The operation is relatively cumbersome, with a large labor intensity and low efficiency. Summary of the Invention

The mobile end of the material pushing rodless cylinder 501 is fixedly connected with a material pushing plate 506 through a notch plate 505.

[0019] As a preferred solution, in order to realize the bagging process of stacked PP cups, the material pushing component 5 is used to push the stacked PP cups into the bag sealing component 6.

[0021] The collection and palletizing method of the above-mentioned contact lens PP cup collector specifically includes the following steps: S1. After the PP cups are placed on the straight section conveying assembly 3, the spacing component 8 spreads the PP cups equidistantly on the straight section conveying assembly 3. Then, the straight section conveying assembly 3 conveys the PP cups to the inclined section conveying assembly 4. Finally, the PP cups fall into the pushing head 707. During this process, the ion blower 9 and the negative pressure dust suction component 10 are started to remove static electricity and dust from the PP cups. S2. The servo motor 702 is started to drive the rotating plate 703 to rotate. The rotating plate 703 drives the connecting rod 704 to make the push rod 706 reciprocate in the positioning sleeve 705. The push rod 706 drives the pushing head 707 to move the PP cups towards the storage baffle 504. The receiving buffer cylinder 502 drives the cross plate 503 to move the storage baffle 504 by one storage station. As the PP cups are continuously conveyed, the PP cups are continuously stacked on the working plate 2 until the storage baffle 504 moves to the notch of the notch plate 505. S3. During the stacking process of the PP cups in S2, the front and rear transverse moving component 603 extends, and the lifting cylinder 602 extends, so that the two first negative pressure suction cups 604 and the two second negative pressure suction cups 605 suck the empty packaging bags from the empty bag area 202. The lifting cylinder 602 contracts, the front and rear transverse moving component 603 contracts, and the transplanting rodless cylinder 601 drives the lifting cylinder 602 to move to the bagging area 203.

The pushing rodless cylinder 501 is started. The moving end of the pushing rodless cylinder 501 drives the notch plate 505 to make the pushing plate 506 push the stacked PP cups into the packaging bag with the supported bag mouth, and then the pushing rodless cylinder 501 is controlled to reset. S5. The heating element 609 is started, the downward pressing cylinder 607 extends, and the downward pressing block 608 is pushed down to squeeze and contact the packaged packaging bag with the heating wire 6011 for bag sealing. After the sealing is completed, the heating element 609 is turned off, and the downward pressing cylinder 607 resets. After the bagging and sealing are completed, the two second negative pressure suction cups 605 adsorb the packaging bag, the front and rear transverse moving member 603 contracts, and the transplanting rodless cylinder 601 drives the lifting cylinder 602 to move to the side of the bagging area 203 away from the empty bag area 202. At this time, the lifting cylinder 602 has moved away from directly above the working plate 2. Move the palletizing trolley to directly below the lifting cylinder 602, that is, the palletizing area. After the two first negative pressure suction cups 604 and the two second negative pressure suction cups 605 break the vacuum, the whole bag of PP cups with the sealing completed falls onto the palletizing trolley to complete the palletizing. Then, the transplanting rodless cylinder 601 resets above the empty bag area to perform the bagging and transfer operation for the next batch.
