Contact lens packaging system {CONTACT LENS PACKING SYSTEM}

The present invention relates to a contact lens packaging system, and more particularly, a contact lens packaging system configured to automatically perform a series of processes of storing, sealing, and unloading a contact lens package for individually sealing a plurality of contact lenses in a packaging box is about

A contact lens is a lens that is mounted on the cornea of the eye for medical purposes such as vision correction or treatment, or for cosmetic purposes. Compared to glasses, there are various advantages such as almost no aberration, a wide field of view, and almost no indication of the wearing state, so they are widely used.

Since the cornea of the eye to which the contact lens is mounted forms a substantially spherical surface, the structure of the contact lens also forms a structure including a front curve, a rear curve, and an edge accordingly.

Contact lenses are generally manufactured by a casting method using a casting mold, and by injecting a monomer, a raw material for contact lenses, into the space formed between the female and male molds and curing the monomer for a certain period of time, to produce a contact lens shape. do.

Since contact lenses are vulnerable to external damage in material and require careful handling, such as maintaining aseptic conditions, most contact lenses are individually sealed in packaging materials such as packaging containers or blister packages, and then stored and supplied in a packaging box. packaging is done.

For example, Korean Patent Registration No. 10-0408580 discloses at least one molded plastic base member having a cavity for accommodating a contact lens and comprising a flange extending outwardly around the cavity and a support wall portion extending from the flange, the cavity a base member comprising a curved concave indentation and having a shape consistent with that of a contact lens suitable for receiving within the cavity; A row packaging container for sealingly receiving a contact lens comprising a flexible cover sheet adapted to be releasably sealed to a flange having a support wall portion at one end of a planar surface extending away from it.

As another example, Korean Patent Registration No. 10 - 1975160 discloses a packaging for contact lenses comprising an individual sealed blister pack and a connecting label including a polymer film, and each of the individual sealed blister packs is a single contact a plastic base member to receive the lens, and a sealing member, wherein a label is affixed to each sealing member of the individual sealed blister packs to constitute packaging that binds the blister packs together.

Korea Patent Registration No. 10 - 0408580 (2005.02.03) Korean Patent Registration No. 10 - 1975160 (2019.05.03) Korean Patent Registration No. 10 - 0912460 (2009.08.14) Korean Patent Registration No. 10 - 1343713 (2013.12.20)

The contact lens packaging technology to which the prior art as described above is applied forms a plurality of cavities in the shape of a contact lens, a plastic base member for accommodating individual contact lenses in each cavity, and a blister comprising a cover sheet attached to and sealed to the base member After the primary packaging is made with the package, a secondary packaging process of accommodating the package in a packaging box is performed.

However, in the conventional contact lens packaging method, the blister packaging process of primary packaging of contact lenses is automated, but the secondary packaging of the package in a packaging box is mostly performed manually by manpower.

A box seating module 120 that picks up the packaging box material from the box supply module 110, makes it three-dimensional, and sits on the box transport module 140;

A lens package supply module 130 for supplying and accommodating individually sealed packages of contact lenses inside the packaging box seated on the box transport module 140;

A box transfer module 140 for fixing the packaging box in which the package is accommodated one unit at a time and transferring it in one direction;

A wing folding module 150 arranged on both sides on the path of the box transfer module 140 to sequentially fold the folding wings of the packaging box being transported;

A wing sealing module 160 for sealing both sides of the packaging box by bonding the folding wings that are finally folded by the wing folding module 150, and;

By including the discharge module 170 for sorting and discharging the packaging box sealed by the wing sealing module 160, a series of processes of accommodating, sealing and unloading the contact lens package in the packaging box can be performed automatically. purpose can be achieved.

The present invention provides a contact lens packaging system that automatically performs a series of processes of accommodating contact lenses individually sealed in packaging materials such as packaging containers or blister packages in a packaging box and taking them out.

Therefore, the present invention has the effect of improving the process quality by minimizing the possibility of errors compared to the conventional manual packaging method by automating the overall contact lens packaging process.

It is made so that both upper folding wings are folded at the same time while passing.

The seventh and eighth folding steps (S100) are steps of simultaneously folding the lower folding wings of both sides of the packaging box to which the adhesive is applied. Among the eight folded wings provided on both sides of the packaging box, the last remaining lower folded wings are folded, and the seventh and eighth folding steps (S100) are a process of applying an adhesive in the wing sealing step (S110) to be described later. do it first and then do it. In the process of being transported through the box transfer step (S50), the upper folded wings on both sides are simultaneously folded while passing through the lower folding slopes 157 of the seventh and eighth blade folding parts 156 of the blade folding module 150. .

The wing sealing step (S110) is a step of sealing both sides by applying an adhesive to the inner surface of the folding wing, which is finally folded in the packaging box, and then pressurizing it. Before carrying out the 7th and 8th folding steps (S100), an adhesive is applied to the inner surfaces of the upper folding wings on both sides by the adhesive part 161 of the wing sealing module 160, and the 7th and 8th blade folding steps After carrying out, the outer surfaces of the lower folding blades on both sides are pressed by the wing pressing unit 162 to achieve complete sealing, and transferred toward the discharge module 170 in a pressurized state while passing through the pressing guide unit 163 . is done

The discharging step (S120) is a step of discharging packaging boxes sealed on both sides one by one, but selecting and discharging defective packaging products by weight measurement. The packaging box transferred to the discharge module 170 through the wing sealing step (S110) as described above is located in the load cell 171 by the discharge guide unit 172, measures the weight, and then moves to the sorting unit 173. fall down The sorting unit 173 is configured to sort and discharge good products and defective products through different paths according to the measurement result by the load cell 171 .

As described above, the contact lens packaging system according to the present invention provides a contact lens packaging system that automatically performs a series of processes of accommodating, sealing, and discharging a contact lens package in a packaging box.

Therefore, the present invention automates the overall contact lens packaging process to improve the process quality compared to the conventional manual packaging method, as well as optimize the system configuration according to the type of packaging box, so the operation of the contact lens packaging system is improved. It is easy and has various advantages such as significantly increasing productivity and efficiency, so it is expected to have a very large industrial application.
