Description

Lens Automatic Packaging Device {.}

The present invention relates to an apparatus for automatically packaging a lens, and in particular, prior to packaging the lens, the data measuring the frequency and thickness of the lens is printed on the wrapping paper, and the lens is put into the wrapping paper where the data is printed by the above process. By automating a series of packaging process, the automatic packaging device that can effectively pack the lens while reducing the waste of manpower by maximizing the amount of work per unit time with a minimum manpower in a small space.

Various lenses are produced with unique frequency and thickness.

The frequency of each lens is measured by a frequency meter, and the measured frequency is printed on the wrapping paper, and the lens is packed in the wrapping paper.

In the automatic packaging of such a lens, when the power of the lens is measured by a frequency measuring device, necessary data including the frequency measured by a printing apparatus having a computer system is printed on the wrapping paper.

Korean Utility Model Registration No. 0180390, 'Lens Automatic Packaging Device', which is designed by the applicant of the present application, is known for an apparatus for printing the frequency measured by a lens frequency measuring device on a wrapping paper and putting the lens into a wrapping paper which has been printed.

In the automatic lens packaging apparatus, the frequency measurement is performed while the lens transferred to the conveyor is aligned by the positioning mechanism, and the measured frequency is input to the computer system and then printed on the wrapping paper by the printing apparatus.

The wrapping paper on which data is printed is discharged and waits for the lens to be inserted, and the lens after measuring the frequency is removed from the conveyor by the feeding mechanism, put into the wrapping paper, and then loaded into the loading mechanism.

The structure of the specific position correction mechanism that enables this operation is detected by the sensor when the lens conveyed by the conveyor reaches the top of the frequency measuring instrument is stopped by the sensor, the end of the piston rod of the pneumatic cylinder is formed with inclined surfaces on both sides Is located above the frequency measuring instrument, and a pair of pincers pulled from each other by a spring is installed between the piston rod and the measuring instrument so as to be movable in a horizontal direction, thereby contacting the inclined surface of the rising and lowering piston rod and pinching the lens on the conveyor. One side of the conveyor is rotated so as to be placed at the frequency measuring center of the frequency measuring instrument, and to seat the lens whose frequency measuring position is determined by the narrow strip on top of the frequency measuring instrument, and to transfer the lens of which the frequency measuring is completed to the lens input device. Possibly fixed on the other side For lifting to pivot in the upper part of the frequency measurement it is also made up of a single pneumatic cylinder.

The lens input mechanism includes a pneumatic cylinder for drawing the lens transferred to the conveyor to the guide chute, a guide chute for storing the lens discharged to the pneumatic cylinder and the wrapping paper discharged from the printing mechanism, and a lens to the wrapping paper housed in the guide chute. A pneumatic cylinder for pushing the wrapping paper to be laid down for feeding, an air spray nozzle for injecting air to expand the inlet of the wrapping paper to inject a lens into the wrapping paper laid by the pneumatic cylinder, and a spray injected from the air spray nozzle The pneumatic cylinder presses both sides of the wrapping paper so that the wrapping paper with the opening enlarged by the wind can be maintained, and the upper part of the guide chute is placed on the top of the guide chute to completely receive the dropped lens on the wrapping paper with the opening opening. Another pneumatic cylinder for pressurizing the upper portion is provided.

This automatic lens packaging device was devised to solve the problem that the measurement error occurs because the center of the lens and the lens for measuring the frequency in the conventional lens frequency measuring device can not be placed in the correct vertical center. By accurately matching the center with the center of the lens in the vertical direction, the power is accurately measured and then wrapped in a printed wrapping paper.

The following problems with the automatic lens packaging device has been found.

First, the position correcting mechanism slides the pair of narrowing zones in a direction close to each other by the pulling force of the spring so that the lens is placed at the measuring position of the frequency measuring instrument. Can be biased. Therefore, when a pair of narrow zones are pushed in either direction at the same time, the lens cannot be positioned at the exact frequency measurement center.

In addition, the lens input mechanism includes a pneumatic cylinder which pushes the wrapping paper to lie down to match the wrapping paper at the position where the lens is dropped in order to put the lens into the wrapping paper stored in the guide chute, and the inlet is opened by the air pressure sprayed from the air jet nozzle. The device is complicated by another pneumatic cylinder which pushes the upper part of the lens to completely receive the lens put into the wrapping paper, and means for restraining the wrapping paper against the wind pressure sprayed from the air jet nozzle are not provided. In other words, there is a structural problem that the packaging is blown out due to the wind pressure and the packaging fails.

In addition, there is no device for measuring the power of the lens as well as measuring the thickness of the lens, etc., so that there is a limit to printing necessary data on the wrapping paper.

An object of the present invention is to provide a lens automatic packaging device capable of accurately measuring the power at all times by automatically matching the center of gravity of the lens measuring meter and the lens center on the correct vertical center line while automatically supplying the lens.

Another object of the present invention is to provide an automatic lens packaging apparatus that can accurately measure the thickness of a lens and print it on a wrapping paper by automatically matching the measuring center of the lens thickness meter with the center of the lens on an accurate vertical center line while automatically supplying the lens. To provide.

Another object of the present invention is the configuration of the lens input mechanism is complicated in the conventional device, and solve the structural problem that the wrapping paper is separated from the work line can prevent the mechanism configuration of the simple lens feeding mechanism and the wrapping paper is separated. The present invention provides an automatic lens packaging apparatus that can reduce manufacturing costs and improve the success rate of packaging operations.

In the forming of the automatic lens packaging device consisting of a loading mechanism for discharging the wrapping paper into which the lens is inserted, and for loading the discharged wrapping paper by frequency, the first lens narrow region of the position correction mechanism is the vertical center of the frequency measuring instrument Space keeping means of the first lens narrow strip to be placed at the same distance from the center symmetrically; Thickness measurement for measuring the thickness of the lens so that the sensor can stop the conveyor by detecting the lens is transferred from the position determined by the interval holding means of the first lens narrow zone and then conveyed to the wrapping paper in the printing mechanism An appliance; A sensor detects a lens conveyed after the thickness is measured by the thickness gauge, and stops the conveyor, accommodates the wrapping paper discharged from the printing apparatus, and is placed horizontally with the conveyor so that one side is rotatably fixed to the conveyor. And, the other side is rotatably fixed to the piston rod of the pneumatic cylinder, characterized in that it comprises a wrapping paper holder having an air jet nozzle to put the lens in the wrapping paper supplied after printing in the printing mechanism.

The automatic lens packaging apparatus of the present invention has a transport system in which conveyors of various stages are installed within a range allowed by the installation space so that the lens can be supplied from one conveyor to another conveyor.

For example, in order to sequentially supply a lens from one first conveyor, a sensor is installed in a frame in which the first conveyor is installed while the second conveyor is disposed in a direction crossing the right angle at the end of the first conveyor. Is stopped when reaching the end of the first drive belt constituting the first conveyor, the first pneumatic cylinder disposed toward the second conveyor is provided with a position correction mechanism for measuring the frequency from the side the lens is stopped Thereby transferring one lens from the first conveyor to the second conveyor.

In the frame where the second conveyor is installed, a detection sensor is installed together with a position correction mechanism, and a frequency measuring instrument is disposed below the position correction mechanism. The lens transferred from the first conveyor reaches the upper portion of the frequency measuring instrument so that the detection sensor is a lens. When the second conveyor stops, the center of gravity is measured by the positioning device.

The second driving belt of the second conveyor is divided into two sides so that the lens placed thereon can be seated in the frequency measuring instrument, and is connected to both roller ends of the conveyor, thereby exposing the frequency measuring meter installed at the bottom and the upper lens. It consists of a pair of belts arranged between the spaces.

The positioning mechanism for measuring the power of the lens includes a pusher fixed to an end of a piston rod of a second pneumatic cylinder fixed to a frame on which a second conveyor is installed to correct the position of the lens, and having inclined surfaces formed on both sides thereof; A pair of first lens narrowing zones which are installed to face each other so as to be in contact with an inclined surface formed on the pusher and to be moved so that the lens can be positioned at the frequency measuring center of the frequency measuring device by holding the lens moved from the second conveyor to the upper part of the frequency measuring device; Wow; The lens is provided with an elastic member installed in the first lens narrow strip so that the clamping gripping grips and releases the lens as the second pneumatic cylinder is operated. One side of the second conveyor is rotatably fixed, and the other side is lifted up and down so as to pivot on the frequency measuring instrument so as to be seated above the frequency measuring instrument, and the lens having completed the frequency measurement can be transferred to the lens input device.

The position correction mechanism detects when the lens to be transferred is located between the first lens narrow regions of both sides at the upper part of the frequency measuring instrument, and the second conveyor is stopped while the operation of the first conveyor and the first pneumatic cylinder is stopped. Next, the second pneumatic cylinder completes one reciprocating operation, and the preliminary alignment process of positioning the lens at the measurement center is performed by the first lens narrow strip holding and releasing the lens with elasticity of the elastic member.

In the one-time reciprocating operation of the second pneumatic cylinder, when the piston rod is lowered and the inclined surface of the pusher formed at the end presses both narrow regions at the same time, the elastic lens is accumulated in the elastic member, and the first lens narrow regions move toward each other. Arrives between the first lens narrow zones, and the first lens narrow zones, which are freed because the piston rod is lifted and are not in contact with the pushers, move toward each other by the tension of the elastic member to grip the lens. .

Here, when the first lens narrow zone is in a state of sliding movement, and the elasticity of the elastic member is repeatedly applied, a pair including the elastic member when the piston rod is raised and there is no lens between the first lens narrow zones. The narrow region of the lens can be biased to either side, and the first lens narrow region maintains a precisely divided distance from the upper part of the measurement center of the frequency measuring instrument by the spacing means.

It is seated horizontally without falling off the meter.

When the lens is placed on the frequency measuring instrument, the second pneumatic cylinder is reciprocated once again so that the pincer grips and disengages the lens to finally coincide with the measuring center.

At this time, the piston rod of the second pneumatic cylinder 20 of the position correction mechanism 2 for measuring the power of the lens is advanced so that the inclined surfaces 26 and 26a of the pusher 25 become the first lens narrow region 22 ( 22a) is pushed outward so that the first lens narrow regions 22 and 22a move along the first fixing shafts 28 and 28a in a spaced apart direction from each other so that the lens L2 can enter. .

As shown in FIG. 3, when the lens L2 is moved to the second driving belts 111 and 111a and reaches the upper portion of the frequency measuring instrument 7, the detection sensor senses the first and second driving belts 101 together with the first driving belt 101. The two driving belts 111 and 111a stop.

In this state, when the piston rod 20a is lowered by the operation of the second pneumatic cylinder 20, the inclined surfaces 26 and 26a of the pusher 25 are slidably installed on the first fixed shafts 28 and 28a. In contact with the first lens narrow strips 22 and 22a, as shown in FIG. 3, the first lens narrow strips 22 and 22a are pushed outward to extend the lens between the first lens narrow strips 22 and 22a. L2 can enter, and the elastic members 23 and 23a accumulate elasticity.

When the second conveyor 11 is stopped, the position correction mechanism 2 is operated to coincide with the center of the frequency measuring instrument 7 and the center of the lens L2.

The state in which this positioning mechanism is operated is shown in FIGS. 3 to 6.

Referring to this drawing, when the detection sensor 220 detects that the lens L2 is located above the frequency measuring instrument 7 and the second driving belts 111 and 111a stop, the second pneumatic cylinder 20 Is activated to raise the piston rod 20a and the pusher 25.

When the pusher 25 is raised, the first lens narrow strips 22 and 22a are guided to the first fixing shafts 28 and 28a by the tensile force of the elastic members 23 and 23a and move inwards to prevent the lens L2. G) on both sides. In this way, the lens L2, which has been misaligned while being transferred, is primarily aligned so that its center of gravity coincides with the center of the frequency measuring instrument 7.

Thereafter, the pusher 25, which is driven by the second pneumatic cylinder 20 and descends, cancels the first lens narrow strips 22 and 22a holding the lens L2, thereby leaving a state as shown in FIG. 3.

When the lens L2 is aligned in this manner, the second conveyor 11 rotates as in the operation of a known device so that the lens L2 is accurately seated on the frequency measuring instrument 7 to perform frequency measurement. After completing the frequency measurement, the second conveyor 11 is raised again and positioned at the same height as the third conveyor 13, and the raised lens L2 is driven by the second driving belts 111 and 111a. It is delivered to the conveyor 12, another lens (L) from the first conveyor (10) is transferred to the second conveyor (11) to continue the continuous packaging operation.

During the operation of the positioning mechanism 2, the inclined surfaces 200 and 200a of the gap holding region 29 which are supported to be lifted and lowered in the vertical direction to the fixing booth 202 are always the first lens narrowing region 22. In contact with 22a, the first lens narrow strips 22 and 22a always maintain the same distance around the frequency measuring instrument 7.

Lens L3 transferred from the position correction mechanism 2 to the thickness measuring mechanism 3, that is, lens L3 transferred from the second driving belts 111 and 111a to the third driving belts 31 and 31a. When the bottom of the thickness measuring instrument 8 and the upper of the third pneumatic cylinder 36 arrives, the detection sensor 32 detects and the third driving belts 31 and 31a stop.

In this case, the second lens narrow regions 22 and 22a are spaced apart from each other on the second fixing shafts 34 and 34a as shown in FIGS. 8, 10, and 11 to allow the lens L3 to enter. When the pneumatic motor 30 operates afterwards, as shown in FIGS. 9 and 12, the horizontal movable stages 35 and 35a are guided to the second fixed shafts 34 and 34a to move inwards. The lens narrow strips 33 and 33a hold the lens L3.

The lens L3 clamped by the second lens pinching zones 33 and 33a is aligned with the center of the disturbance in the process of being transported, and the center portion of the lens L3 is vertically formed by the thickness gauge 8 and the third pneumatic cylinder 36. Exactly in the center

Thereafter, the third pneumatic cylinder 36 is driven to raise the piston rod 39. As shown in FIG. 13, the piston rod 39 supports the lens L3 to contact the lower end of the thickness gauge 8. To be.

At this time, the second lens narrow regions 33 and 33a holding the lens L3 are guided to the guide grooves 38 and 38a of the horizontal movable plates 35 and 35a and rise together with the lens L3. .

The thickness measurement of the lens L3 is determined by the distance that the piston rod 39 of the third pneumatic cylinder 36 has risen until the moment the lens L3 comes into contact with the lower end of the thickness gauge 8 and stops.

The data measured by the thickness gauge 8 is calculated in a known computer system 50 and printed on the wrapping paper P by the printing mechanism 5.

On the other hand, one wrapping paper P printed with the frequency and thickness in the printing mechanism 5 is dropped along the wrapping paper discharge chute 52 by a known discharge mechanism as shown in Figs. It is supplied to the wrapping paper storage base 44 of the lens input mechanism (4) while being caught by the stopper (403).

When the sensing sensor 404 formed on the horizontal fixing stand 402 detects the moment when the wrapping paper P1 arrives at the wrapping paper storage box 44, the fifth pneumatic cylinder (as shown in FIGS. 17, 19, and 21) is illustrated. 410, 410a is driven to advance the first wrapping paper narrow zone 46, 46a toward the wrapping paper P1, compressing the wrapping paper P1, and at the same time, the air is sprayed from the air spray nozzle 45, thereby wrapping the wrapping paper ( Open the inlet of P1).

When the inlet of the wrapping paper P1 is opened, the air injected from the air spray nozzle 45 is stopped, and the sixth pneumatic cylinders 411 and 411a are continuously driven so that the second wrapping paper narrowing region 47 and 47a is opened. Pressing the wrapping paper (P2) to maintain the open state of the open wrapping paper (P2).

At this time, the protruding ends 400 and 400a of the first wrapping paper narrow zone 46 and 46a are positioned on the upper surface of the wrapping paper P2 so that the wrapping paper P2 is not separated from the wrapping paper storage stand 44 due to the wind pressure. Do not let it.

In this state, when the fourth pneumatic cylinder 43 is driven to push the lens L3 toward the wrapping paper storage box 44, the lens L3 is stored in the wrapping paper P2.

When the lens L5 is inserted into the wrapping paper P2 by the operation of the fourth pneumatic cylinder 43, the fifth and sixth pneumatic cylinders 410, 410a, 411 and 411a are driven back to the first package. When the isthmus region 46, 46a and the second pavement isthmus region 47, 47a are pushed in the direction away from each other, the wrapping paper P2 carrying the lens L5 is free.

Thereafter, when the seventh pneumatic cylinder 401 is driven and the piston rod 405 is pulled, the packing holder 44 is pivoted about the fixed shaft 406 as shown in FIG. Wrapping paper (P2) carrying the will be sent to the loading mechanism (6).

When the wrapping paper P2 is discharged to the loading mechanism 6, the piston rod 405 of the seventh pneumatic cylinder 401 is advanced again, and the wrapping paper storage stand 44 is horizontally placed again to receive the wrapping paper and the lens. do.

Since the structure and operation of the loading mechanism 6 in which the wrapping paper carrying the lens is loaded are the same as those of the known apparatus, detailed description thereof will be omitted.
