Figure is shown.

As shown in these drawings, the polarizing film stacking apparatus 100 according to an embodiment of the present invention, the film transport unit 110 for transporting the cut polarizing film (F, see FIG. 2), and the film transport unit The container input unit 120 and the end of the film transfer unit 110 to be inserted or taken out, the loading container 121 is provided in the lower portion of the 110 and the polarizing film (F) falling from the film transfer unit 110 is loaded The guide unit 130 is provided in the area and guides the falling path of the polarizing film F when the polarizing film F falls from the film transfer unit 110, and can enter and exit into the guide unit 130. The fork unit 140 is provided between the film transfer unit 110 and the container input unit 120 so that the polarizing film F that is dropped from the film transfer unit 110 is temporarily loaded when the loading container 121 is replaced. ).

By this configuration, not only the predetermined number of polarizing films F can be smoothly loaded in the loading container 121, but also the loading container 121 in the container loading unit 120 for replacement of the loading container 121. Even if there is no, by temporarily loading the polarizing film (F) to the fork unit 140 can improve the efficiency of the loading operation of the polarizing film (F), thereby improving the overall productivity of the polarizing film (F) manufacturing work Can be improved.

Referring to each configuration, first, as shown in FIG. 2, the film transport unit 110 includes a first transport conveyor 111 in which a polarizing film F cut into a unit size is first loaded and transported. And a second transfer conveyor 112 disposed at the rear of the first transfer conveyor 111 and driven relatively faster than the first transfer conveyor 111 so as to space apart the polarizing films F.

Here, the second transfer conveyor 112 may be driven at a higher speed than the first transfer conveyor 111 to separate the polarizing films F contacted and transferred on the first transfer conveyor 111 to be spaced apart from each other. . In other words, the polarizing films F which have been laterally contacted by the relative speed difference between the first transfer conveyor 111 and the second transfer conveyor 112 are transferred from the first transfer conveyor 111 to the second transfer conveyor 112. It can be separated separately when transported to).

For example, if the first conveyer 111 is driving the polarizing film (F) while driving at a speed of 50m / min, the second conveyer 112 is faster than the speed of 50m / min, for example 60m / min The polarizing films (F) are transported while driving at a speed of. Therefore, when the polarizing film (F) is crossed from the first conveying conveyor (111) to the second conveying conveyor (112), the interval between the polarizing films (F) may be spaced apart. It can be. Accordingly, the loading operation of the polarizing film F to be described later may be smoothly performed.

As shown in FIG. 2, the first transfer conveyor 111 and the second transfer conveyor 112 may be, but are not limited to, a belt type conveyor, and a roller type conveyor may be applied. .

On the other hand, the film conveying unit 110, as shown schematically in FIG. 2 so that the polarizing film (F) can be accurately conveyed without being pushed or deviated during the transfer operation of the polarizing film (F), the first The first rotary support part 114 provided at the connection part of the transfer conveyor 111 and the 2nd transfer conveyor 112, and the 2nd rotary support part 115 provided in the distal area | region of the 2nd transfer conveyor 112 are further added. Equipped. The first rotary support 114 and the second rotary support 115 is provided in a substantially same configuration, but is provided in a roller type that rotates in place.

The first rotary support part 114 is provided on the tip end portion of the second transfer conveyor 112 adjacent to the first transfer conveyor 111. The first rotary support 114, the first transfer conveyor 111 and the second transfer conveyor 112 when the polarizing film F on the first transfer conveyor 111 is transferred onto the second transfer conveyor 112. The polarizing film (F) in the connection portion of the serves to push the polarizing film (F) in the direction of the second conveying conveyor 112 to prevent the direction or shift. Therefore, the polarizing film F on the first transfer conveyor 111 may be smoothly transferred onto the second transfer conveyor 112.

The second rotary support 115 is provided in the distal region of the second transfer conveyor 112 so that the polarizing film F can be smoothly dropped to the loading container 121 of the container input unit 120 to be described later. That is, before the polarizing film F reaches the end region of the second conveying conveyor 112 and falls to the loading container 121, the polarizing film F which is conveyed at high speed may be pushed to one side or the direction may be distorted. At this time, the second rotation support part 115 rotates relative to the polarizing film F to the outside so that the polarizing film F can fall in the direction of the loading container 121 of the container feeding unit 120 without being distorted in the direction. do.

Meanwhile, as shown in detail in FIG. 3, the container input unit 120 includes a loading container 121 on which the polarizing film F is loaded, and a container transfer conveyor 123 for transferring the loading container 121. do.

 The stacking container 121 is a portion in which a predetermined number of polarizing films F are loaded and stored, and the loading container 121 in which a predetermined number of polarizing films F is loaded is loaded by a container transfer conveyor 123. After being transferred to the inlet of the container 121, it is stacked and stored in an external storage location.

The container transfer conveyor 123 is a conveyor for transferring the loading container 121. When the loading container 121 is inserted into the loading container 121 inlet, the container transfer conveyor 123 operates to drop the polarizing film F. The loading container 121 may be transferred to a position where the loading container 121 is filled. On the contrary, when a predetermined number of polarizing films F are filled in the loading container 121, the loading container 121 may be transferred to an inlet of the loading container 121 so that the loading container 121 may be moved. The loading container 121 can be taken out outside by a conveying apparatus (not shown).

This container transfer conveyor 123, as shown in Figure 3, is provided as a roller-type conveyor that rotates about the axis in place. However, this is only one embodiment, and may be provided as a belt-type conveyor or the like.

In addition, the container transfer conveyor 123 is capable of moving up and down as a whole. Therefore, after the loading container 121 is transferred to the position where the polarizing film F is dropped by the driving of the container transfer conveyor 123, the container transfer conveyor 123 is lifted as a whole, so that a part of the loading container 121 is guided. It may be drawn into the inside of the 130, thereby allowing the loading operation of the polarizing film (F) to proceed more smoothly.

On the other hand, the guide unit 130 serves to prevent the polarizing film (F) from the path when the polarizing film (F) falls from the second transfer conveyor 112 to the loading container 121.

The guide unit 130, as shown in detail in Figures 3 to 5, is provided on the upper portion of the above-described loading container 121 and polarized when the polarizing film F is dropped from the second transfer conveyor 112 When the polarizing film F is dropped from the second conveying conveyor 112 by being spaced apart from the front guide wall 131 and the rear side of the front guide wall 131 to prevent the film F from escaping forward. A pair of side surfaces provided to be movable in an inward direction between the rear guide wall 132 and the front guide wall 131 and the rear guide wall 132 to prevent the polarizing film F from deviating backward. The guide wall 133 is provided.

The front guide wall 131 and the rear guide wall 132 are spaced apart side by side in the height direction, a portion of the fork unit 140 to be described later is drawn between the front guide wall 131 and the rear guide wall 132. It is provided with a comb tooth structure formed with a plurality of openings.

The front guide wall 131 is loaded by allowing the polarizing film F falling in the diagonal direction from the second conveying conveyor 112 to fall into the loading container 121 after hitting the front guide wall 131. The polarizing film F stacked on the container 121 may be aligned to some extent. The front guide wall 131 can be approached and spaced apart in the direction of the second transfer conveyor 112 according to the operator's setting, and accordingly, according to the size of the polarizing film F loaded on the loading container 121. It can be properly adjusted.

In addition, as described above, when the polarizing film F is dropped from the second conveying conveyor 112 to the loading container 121, the polarizing film F is not directly lowered downward, but slips in a diagonal direction. At the upper end of the rear guide wall 132, a sliding wall 137 (see FIG. 4) connected to the distal end portion of the second transfer conveyor 112 in an oblique manner is provided.

The side guide wall 133 not only prevents the polarizing film F from escaping laterally but also plays a role of aligning the polarizing film F. FIG. The side guide wall 133 is operated during the operation of the fork unit 140 to be described later will be described in detail when the fork unit 140 is described.

On the other hand, in order to prevent the upper and lower portions of the polarizing film F from being reversed and loaded into the loading container 121 when the polarizing film F falls into the loading container 121, air is provided behind the rear guide wall 132. Blower unit 150 for ejecting is mounted.

The blower unit 150 is disposed on top of the fork unit 140 to be described later in the rear region of the rear guide wall 132 and temporarily polarized on the fork unit 140, as shown in detail in FIGS. 5 and 6. The upper blower 151 which injects air toward the polarizing film F when the film F is loaded, and is disposed below the upper blower 151 in the rear region of the rear guide wall 132 and the polarizing film F ) Is provided with a lower blower 153 for injecting air when loaded into the loading container 121.

By this configuration, when the polarizing film F is temporarily loaded in the fork unit 140, or when the polarizing film F is loaded in the loading container 121, the polarizing film F is not turned over and is correctly positioned. Can be loaded on.

On the other hand, when the predetermined number of sheets of the polarizing film (F) is loaded on the loading container 121, the loading container 121 is completed to be taken out to be stored in the external loading space. At this time, when a predetermined number of polarizing films F are loaded in the loading container 121 and no more polarizing films F can be loaded in the loading container 121, the polarizing film F is temporarily loaded. In order to operate the fork unit 140 to be described later, the polarizing film stacking apparatus 100 of the present embodiment is provided on the second conveying conveyor 112 and the number of polarizing films F loaded on the stacking container 121. And a sensing unit (not shown) for sensing the control unit and a control unit (not shown) for controlling the operation of the fork unit 140 based on the sensing signal from the sensing unit.

In more detail, for example, when the number of polarizing films F that can be loaded in one loading container 121 is 100, the sensing unit may drop the number of 100 polarizing films F falling from the second transfer conveyor 112. After detecting the information to the control unit, the control unit operates the fork unit 140 based on the information from the detection unit fork unit polarized film (F) that falls while the loading container 121 is replaced Allow 140 to load temporarily.

As described above, the fork unit 140 may load the polarizing film F temporarily during the replacement time of the loading container 121 so that the loading operation of the polarizing film F may proceed without interruption. Compared to the polarization film loading device 100 plays a role of improving the overall productivity.

As shown in FIG. 4, the fork unit 140 of the present embodiment includes a fork hand 141 partially inserted into the opening of the front guide wall 131 through the above-described rear guide wall 132, and A hand driver (not shown) for driving the fork hand 141 is provided.

The plate direction of the fork hand 141 has a horizontal direction parallel to the plate direction of the front guide wall 131 and the rear guide wall 132, that is, substantially parallel to the ground, so that the fork hand 141 is When selectively disposed between the guide units 130, the polarizing film F falling from the second transfer conveyor 112 may be temporarily loaded.

The fork hand 141 is operated by the driving force of the hand drive unit. In addition, the hand drive unit is operated by the control unit as described above. That is, when the control unit drives the hand drive unit based on the signal obtained by the sensing unit, the fork hand 141 is inserted between the guide unit 130 by the driving force of the hand drive unit and falls from the second transfer conveyor 112. (F) can be temporarily loaded.

On the other hand, when the fork hand 141 is operated by the control unit by the driving force of the hand drive unit, the timing at which the fork hand 141 moves forward and backward in the direction of the guide unit 130 is important. In more detail, the polarizing film F drops the polarizing film into the loading container 121 at a predetermined time interval by the operation of the film transfer unit 110, in which case the fork is replaced when the loading container 121 is replaced. The hand 141 is advanced toward the front guide wall 131 of the guide unit 130.

However, if the forward speed of the fork hand 141 does not substantially coincide with the speed at which the polarizing film F falls during this process, that is, the fork hand 141 is not interposed between the guide units 130 at an appropriate timing. If not, the polarizing film (F) to be loaded in the loading container 121 may interfere with the fork hand (141) and may not be properly loaded. As a result, the work in which the polarizing film (F) is temporarily loaded in the fork hand (141) may be prevented. Problems that do not occur smoothly may occur.

Therefore, in order to overcome this problem, in the present embodiment, the polarizing film F to be last loaded on the loading container 121 of the polarizing film F transferred through the film transfer unit 110 is the loading container 121. The polarizer film F is properly loaded in the fork hand 141 by controlling the forward movement of the fork hand 141 so as to be substantially the same as the conveying speed of the polarizing film F which is dropped into the next and then dropped. To be possible.

On the contrary, when the loading container 121 is replaced and the fork hand 141 needs to be reversed to the rear of the rear guide wall 132, the fork hand 141 may be precisely considered in consideration of the timing in which the polarizing film F falls. By reversing, the polarizing film F temporarily loaded in the fork hand 141 and the polarizing film F falling from the film transfer unit 110 can be smoothly loaded in the newly replaced loading container 121. do. Here, when the fork hand 141 moves backward, the polarizing films F loaded on the upper surface of the fork hand 141 collide with the rear guide wall 132, thereby temporarily placing the polarizing film loaded on the fork hand 141. (F) can be smoothly loaded in the loading container.

Therefore, unlike the prior art, the loading operation of the polarizing film (F) can be continuously carried out even during the time when the loading container 121 is replaced, it is possible to improve the loading efficiency of the polarizing film (F).

However, in order to transfer the polarizing films F loaded on the fork unit 140 to the loading container 121 of the container loading unit 120, the alignment of the polarizing films F on the fork unit 140 is aligned. To some degree. As described above, the polarizing film F on the fork unit 140 is aligned in the front and rear directions by the front guide wall 131, and the alignment in the lateral direction is the side guide wall 133. Is executed by

That is, the pair of side guide walls 133 are polarized in the fork unit 140 by performing alignment while pushing inward from both sides with the polarizing film F loaded in the fork unit 140 interposed therebetween. The film F may be aligned to some extent. In addition, the aligned polarizing films F may be dropped into the loading container 121 as the fork hand 141 retreats backward and may be loaded into the loading container 121.

Here, if the configuration of the side guide wall 133 will be described in detail, the pair of side guide walls 133 are moved to the guide body 135 in which the moving rails 134 are formed, as shown in detail in FIG. 3. Possibly combined. Although not shown, the pair of side guide walls 133 may be driven by a guide driver (not shown) to linearly move along the moving rails 134 of the guide body 135. F) can be gathered squarely inward.

Hereinafter, a method of operating the polarizing film stacking device 100 having such a configuration will be described.

After the circular polarizing film is cut into a predetermined unit size through a separate polarizing film cutting unit (not shown), the cut polarizing film F is loaded on the first conveying conveyor 111 of the film conveying unit 110 to be predetermined. At a speed of 50 m / min. The polarizing film F transferred by the first transfer conveyor 111 is transferred to the second transfer conveyor 112 and then transferred to the container input unit 120 by circulation of the belt of the second transfer conveyor 112. . However, at this time, the belt circulation speed of the second transport conveyor 112 is circulated by the belt of the first transport conveyor 111 so that the polarizing films F contacted with each other on the first transport conveyor 111 may be spaced apart from each other. Fast compared to speed

Subsequently, the polarizing film F conveyed by the second conveying conveyor 112 is a loading container 121 of the container dispensing unit 120 along the sliding wall 137 provided at the distal end portion of the second conveying conveyor 112. It is dropped to and stacked on top of the loading container 121. However, in order to prevent the polarizing film F from deviating from the falling path during the dropping process of the polarizing film F, the guide unit 130 is provided on the upper portion of the loading container 121, and as a result, the second transfer is performed. The polarizing film F falling from the conveyor 112 may be smoothly loaded in the loading container 121.

Meanwhile, the fork hand 141 of the fork unit 140 while the operation of replacing the loading container 121 filled with the predetermined number of sheets of the polarizing film F in the loading container 121 with a new loading container 121 is in progress. ) Is introduced into the guide unit 130, the polarizing film F falling from the second transfer conveyor 112 may be temporarily loaded. The operation of the fork unit 140 is controlled by the control unit based on the detection signal from the detection unit. Therefore, the loading operation of the polarizing film F may be continuously performed by the fork unit 140 even during the replacement process of the loading container 121, thereby improving the efficiency of the loading operation of the polarizing film F.

As described above, according to the present exemplary embodiment, a predetermined number of polarizing films F are stacked in the loading container 121, and the polarizing film is temporarily placed on the fork unit 140 while the replacement operation of the loading container 121 is performed. F) can be loaded, and thus the stacking operation of the polarizing film F can be continuously performed without interruption, thereby improving the efficiency of the stacking operation of the polarizing film F, and also Improve overall productivity.

In the above-described embodiment, it has been described that the opening of the comb teeth is provided in the guide unit for the entry and exit of the fork unit, but the shape of the guide unit is not limited thereto, and the entry and exit portions to which the fork unit can enter and exit are different from the guide unit. It may be arranged.
