Description

TECHNICAL FIELD [0001] The present invention relates to an alignment device for contact lenses,

More particularly, the present invention relates to a blister pack for a contact lens in which an aqueous solution and a disposable contact lens are built in, and prevents contamination and breakage of the contact lens when carrying a plurality of such blister packs And to minimize the volume of the blister pack.

In general, a blister pack is formed by thermoforming a plastic sheet to form at least one recessed space, placing the article in the space, covering the opening with paper, a synthetic resin film, a metal film, etc., , Small household appliances and small daily necessities.

Among them, the contact lens is directly contacted with the wearer's eyeball, so packaging is required to minimize bacterial inflow, deformation or breakage. Particularly, a disposable soft contact lens packaged with a liquid such as saline, such as a silicone hydrogel lens, .

In Korean Patent Registration No. 10-1218513, as shown in Fig. 1, a base member including a hydrophobic material and having sidewalls contacting the bottom surface and the bottom surface to form a cavity, and a liquid And a silicone hydrogel contact lens positioned in the liquid, wherein the silicone hydrogel contact lens is free of surface treatment, and is capable of forming a cavity without requiring an anti-fouling agent selected from the group consisting of surfactants, surface modification of the bottom surface, Is not attached to the bottom surface or side wall of the contact lens package.

As described above, since the contact lens blister pack includes a liquid such as a contact lens and a saline solution, the contact lens blister pack is heavier than a blister pack such as a general medicine. Therefore, when a plurality of contact lens blister packs are stacked or packed in a box There is a problem that the contact lens blister pack is deformed by the load, saline water is counted, or the contact lens is deformed. In addition, because of the protruding portion where the contact lens is embedded, the packing efficiency is relatively low because the packing is relatively large.

3 and 4 are a front view and a top view, respectively, of a blister pack alignment apparatus for a contact lens according to the present invention, and the detailed structure of a blister pack alignment apparatus for a contact lens according to the present invention is as follows.

In the alignment device for a contact lens blister pack 10 constructed as described above, the two base frames 20 are coupled to the base rail 21 so as to be separated from each other to the left and right, and a tilting cylinder 31, A tilting unit 30 which is tilted 90 ° about the center of the base frame 20 and which is tilted on the upper side and which is symmetrically connected to the upper center of the base frame 20, And a vacuum unit (40) provided on the tilting unit rail (33) with a height difference on the basis of the base frame (20) so as to face each other. Is a blister pack sorting device.

One of the base frames 20 is fixedly coupled to the base rail 21 and the other is movable to the left and right by a cylinder or a motor and the base rail 20 Is provided with a base rail step (21a). The vacuum unit 40 coupled to the base frame 20 to which the vacuum unit 40 coupled to the base frame 20 moving right and left by the base rail step 21a is fixedly coupled, It is possible to prevent the blister pack for contact lenses from being damaged.

In addition, the base frame 20 can be designed and changed in such a manner that both of the base frames 20 can be moved laterally by a cylinder or a motor, so that the base rail step 21a can be provided on both sides.

One of the base frames 20 is fixedly coupled to the base rail 21 and the other is movable to the left and right by a cylinder or a motor and the base rail 20 The vacuum unit 40 is provided with a base rail step 21a or a lower vacuum unit 41 based on the base frame 20 of the two vacuum units 40. The vacuum unit 40 has a blister pack- And a vacuum unit 40 in which a vacuum means 41 is formed on the basis of the base frame 20 is provided with a blister pack coupling guide 42 on the lower side.

This is because the vacuum means 41 is fixed in contact with the semi-spherical storage portion 11 in which the contact lens and the aqueous solution are contained. The storage portion 11 is not located at the center of the contact lens blister pack, When the blister pack side projections 13 for one side of the contact lenses are engaged with the blister pack front side projecting grooves 14a for contact lenses on the other side when the blister pack for a pair of contact lenses is engaged The blister pack engaging guide 42 comes close to or comes into contact with the grip portion 12 side in order to prevent the blister pack for the contact lens from being separated from the vacuum means 41. [

FIG. 5 is a photograph of a blister pack alignment apparatus for a contact lens according to the present invention and an additional apparatus for using the same, and FIG. 6 is a cross-sectional view of a blister pack alignment apparatus for a contact lens according to the present invention, An operation example of the blister pack alignment apparatus for a contact lens according to the present invention will be described below with reference to a photograph of the apparatus.

In order to implement the blister pack alignment apparatus for a contact lens according to the present invention, two conveyors (50) for transferring two blister packs for contact lenses are provided in parallel between two base frames (20) And a coupling unit 60 having two pairs of clamps 61 that are vertically and horizontally moved by a cylinder or a motor and spaced apart from a lower end of the conveyor.

The two contact lens blister packs are transported by the two conveyors 50 around the base rail 21 and the storage part 11 is laid so as to face either the left side or the right side. More specifically, as shown in Fig. 3, the respective blister pack storage portions 11 for contact lenses are transported in a state of being directed to the right.

When the transfer is completed, the tilting unit 30 tilts the vacuum means 41 by 90 DEG toward the lower side. Thereafter, after the storage unit 11 is coupled with the vacuum unit 40 to each contact lens blister pack by the vacuum means 41, the blister pack for each contact lens is again retracted by the tilting unit 30 The vacuum unit 40 is returned to the home position so as to face each other.

Thereafter, as shown in FIG. 6A, the two base frames 20 move toward the center of the base rail 21, and a pair of contact lens blister packs come close to each other.

At this time, the blister pack storage part 11 for a contact lens on one side and the blister pack storage part 11 for a contact lens on the other side are arranged to be shifted from each other.

Thereafter, as shown in Fig. 6 (b), the coupling unit 60 is lowered between the respective vacuum means 41, and the blister pack side projections 13 for one side of the contact lenses are pushed by the clamps 61, And to the blister pack front projection groove 14a for a contact lens.

After the vacuum means 41 and each contact lens blister pack are separated and the two base frames 20 are moved away from each other, the coupling unit 60 is moved as shown in FIG. 6C The pair of contact lens blister packs having been coupled to the tray are moved.

Accordingly, the process loss for separately joining the contact lens blister pack after the transfer can be remarkably reduced, and the packing efficiency can be maximized by significantly reducing the volume of the plurality of contact lens blister packs.

Although the present invention has been shown and described with respect to specific embodiments and applications thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims.
