As the information society develops, the demand for display devices is increasing in various forms.In recent years, liquid crystal display (LCD), plasma display panel (PDP), electro luminescent display (ELD), and vacuum fluorescent display (VFD) have been developed. Various flat panel display panels have been studied, and some are already used as display devices in various devices.

Among them, flat panel display panel is the most widely used as a substitute for CRT (Cathode Ray Tube) for mobile image display because of its high image quality, light weight, thinness and low power consumption. In addition to the use of the present invention, a variety of applications such as a television, a computer monitor, and the like for receiving and displaying broadcast signals have been developed.

Such a flat panel display panel is manufactured through a number of manufacturing processes, which can be roughly divided into three processes, for example, a substrate manufacturing process, a cell manufacturing process, and a module process.

Accordingly, the operation of the interlayer lift according to the present invention will be described in detail by way of examples. Each element mentioned below should be understood with reference to the above description and drawings.

7a to 8b is an operation diagram showing an operating state of the interlayer lift according to the present invention. Here, FIG. 7A is a front view showing that the cassette supplied to the interlayer lift is lifted, FIG. 7B is a side view showing that the cassette supplied to the interlayer lift is lifted, and FIG. 8A shows the cassette supplied to the interlayer lift is lowered 8B is a side view showing that the cassette supplied to the interlayer lift is lowered.

First, when the cassette 20 on which the flat panel display panel 10 is seated by the supply conveyor enters into the input unit 140 of the interlayer lift 100, the cassette is picked up by the pickup roller 142 provided in the input unit 140. 20 is fed to the feed roller 144 side of the injection unit 140. The cassette 20 conveyed to the input unit 140 is detected by the input detection sensor 146 provided at the tip of the feed roller 144, and the input detection sensor 146 provided at the rear end of the feed roller 144.

When the cassette 20 is sensed to be transferred to the correct lift position by the input detection sensor 146, the input of the cassette 20 is completed, and the cassette 20 is moved by the lift driver 120 and the lift unit 130. Transfer operation starts.

At this time, the cassette 20 introduced into the input unit 140 is selectively limited to the entry by the entry limiting device (not shown). That is, when the cassette 20 is already inserted into the input unit 140, the entry path of the cassette 20 is blocked to restrict the entry of the cassette 20. In addition, the cassette 20 which has already entered the feeder 140 is buffered by an inertia (not shown) positioned at the rear end of the feed roller 144, and the moving inertia is buffered and devoted to the feed roller 144.

First, the transfer operation of the lifting drive unit 120 and the lifting unit 130 will be described. The motor 137 of the lifting unit 130 is rotated to rotate the rotary cam 133, and as the rotary cam 133 is rotated, the linkage bar 138 linked to the rotary cam 133 is vertically moved. Accordingly, a plurality of rotating links 134 provided to be rotated by the interlocking bar 138 is rotated so that the supporting end 136 (see FIG. 3) of the rotating link 134 does not support the cassette 20.

In this state, the elevating motor 122 of the elevating driver 120 rotates in the forward direction, and the rotational force generated by the elevating motor 122 is transferred to the timing belt pulley 124b through the reducer 126, the gear box 128, and the like. The lifting unit 130 connected to the timing belt 124a is moved downward.

On the other hand, as the lifting unit 130 is moved, the rotating link 134 provided at the lowermost end of each of the rotating links 134 provided in the lifting unit 130 is moved to the lower side of the cassette 20 introduced into the input unit 140. . Accordingly, the motor 137 of the lifting unit 130 rotates the rotary cam 133 to vertically move the interlocking bar 138, and the interlocking bar 138 when the position of the rotary cam 133 rotates 180 ° with respect to the initial position. Rotating link 134 is rotated to a position for supporting the cassette (20).

When the rotation link 134 of the lifting unit 130 is rotated to a position for supporting the cassette 20, the lifting motor 122 of the lifting driving unit 120 is reversed as shown in FIGS. 7A to 7B. Rotate to rotate the timing belt 124a in the opposite direction to move the lifting unit 130 connected to the timing belt 124a in the upward direction.

As the lifting unit 130 is moved upward, the rotating links 134 that maintain the pivoted state in the direction for supporting the cassette 20 support the lower portion of the cassette 20. The cassette 20 is supported by a plurality of rotating link 134 is transported in the upper direction, such as the lifting unit 130.

Meanwhile, the elevating unit 130 transported by the elevating driving unit 120 has a moving clearance equal to or slightly larger than a moving clearance such as an interval between the input unit 140, the support unit 150, and the discharge unit 160 maintaining the same interval. It is supposed to have

Therefore, when the lifting unit 130 moved by the lifting unit 120 is moved by the interval of the input unit 140, the support unit 150, and the discharge unit 160 maintaining the same interval, the lifting motor of the lifting unit 120 is moved. 122 is rotated again in the forward direction to lower the lifting unit 130 again.

At this time, the position of the cassette 20 moved by the lifting unit 130 is located on the upper portion of the support portion 150 located in the upper portion of the input portion 140, the support portion 150 located in the lower portion of the moved cassette 20 Actuator 156 is operated to move each support panel 154 in the direction of supporting the cassette (20).

Accordingly, as shown in FIGS. 8A to 8B, the cassette 20, which is maintained by the lifting unit 130 that is lowered, is supported by the pair of support panels 154 while the pivot link of the lifting unit 130 is supported. 134 is released in the supported state. At the same time, as the motor 137 of the lifting unit 130 is rotated again, the rotation link 134 is rotated in a direction in which the cassette 20 is not supported.

In addition, as described above, while the lowering operation of the elevating unit 130 is in progress, the input unit 140 maintains a state in which another cassette 20 is inserted and maintains a state of elevating by the elevating unit 130 which is lowered. do. As described above, while the lifting operation of the cassette 20 introduced into the input unit 140 is repeatedly performed, the cassette 20 introduced into the input unit 140 is elevated.

However, when the elevating unit 130 repeatedly performs the elevating operation, the cassette 20, which is first introduced into the support unit 150 positioned above the input unit 140, is supported. Therefore, the cassette 20 supported by the support 150 is supported and lifted by another pivoting link 134 positioned above the pivoting link 134 for transporting the cassette 20 positioned in the inlet 140.

In addition, when the cassette 20 supported by the support part 150 is transferred upward, the actuator 156 of the support part 150 is operated so that each support panel 154 does not support the cassette 20. The cassette 20 is moved to be positioned between the support parts 150.

Therefore, while the cassette 20 to be additionally added is lifted and passed through the support part 150 positioned at the upper part of the input part 140, it becomes a state that can be supported by the support part 150 again.

Accordingly, the elevating driver 120 and the elevating unit 130 of the interlayer lift 100 according to the present invention repeatedly insert the cassette 20 inserted into the inlet unit 140 while repeatedly performing the above-described operation. Transfer to the support 150 is located in the, and the cassette 20 transferred to the support 150 is transferred to the discharge unit.

Here, the number of the support 150 may be formed in various ways, such as the height between the layers, the height of the object to be transferred. However, each support 150 will be described only the operation of one support 150 by repeatedly performing the same operation.

When the cassette 20 supported by the support unit 150 is located above the discharge unit 160, the discharge actuator 165 of the discharge unit 160 is operated to move the discharge panel 164 of the cassette 20. Move downward The roller unit 161 provided on the upper portion of the discharge panel 164 is located at the lower portion of the cassette 20. Accordingly, the lift driving unit 120 is rotated forward again, and the lifting unit 130 is moved downward and the cassette 20 supported by the rotation link 134 is supported by the discharge unit 160.

In this process, each of the pivoting links 134 of the elevating unit 130 allows the cassette 20 to be inserted into the input unit 140 and the cassette 20 supported by the support unit 150 to be lifted discontinuously. do.

On the other hand, the cassette 20 supported by the discharge unit 160 is transferred to the outside of the discharge unit 160 by the roller unit 161 of the discharge unit 160, when the transfer of the cassette 20 is completed, The discharge panel 164 of the discharge unit 160 is moved in a direction not supporting the cassette 20, and waits for the cassette 20 to be elevated later.

Accordingly, the interlayer lift 100 according to the present invention repeatedly transfers the cassette 20 supplied by repeatedly performing the operation as described above to the input unit 140, the support unit 150, and the discharge unit 160. Interlayer transfer can be performed.

In addition, even if the cassette 20 supplied by the supply conveyor is not introduced into the input unit 140 due to an error, time difference, or the like, the lifting operation of the remaining cassettes 20 may be continuously performed without stopping.

In addition, the cassette 20, the lifting operation of the cassette 20 and the discharge operation of the cassette 20 can be carried out at the same time the process of lifting the cassette 20 by the lifting unit 130, the cassette 20 It can shorten the transfer time between layers.
