In a state where the work table 31 is located in the initial position, the operator pushes the tray into the work table 31 after filling the drying target in the tray placed on the work table. Accordingly, when the tray is completely placed on the work table 31, the seating detection unit 162 detects that the tray is placed on the work table 31 and transmits a second detection signal to the control device 140a.

When the control device 140a receives the second detection signal (S1006), it operates the vertical driving unit 120 to vertically move the worktable 31 downward (S1007). Here, when the work start position is set higher than the initial position, the control device 140a vertically moves the work table 31 upward. While the vertical driving unit 120 operates, the control device 140a operates the vertical movement distance measuring unit 170 to measure the distance.

On the other hand, if the seating detection unit 162 is not configured, the operator pushes the tray into the work table 31 and then manipulates the console box 130a to notify the start of the work, and the control device 140a starts the work. By operating the vertical driving unit 120 according to the signal, the work table 31 is vertically moved downward. That is, in the case where the seating detection unit 162 is not configured, the process S1006 is omitted and the process S1007 corresponding to the work start signal is performed.

While the worktable 31 is vertically moving, the start position detection unit 163 detects the work start position flag and transmits a third detection signal accordingly to the control device 140a. When the control device 140a receives the third detection signal (S1008), it stops the worktable 31 and sets the position at this time as the work start position (S1009).

And the control device 140a receives and stores the first distance measured by the vertical movement distance measuring unit 170 (S1010). Then, the control device 140a operates the horizontal driving unit 110 to move the guide 32 in the horizontal direction or to move the work table 31 horizontally so that the tray placed on the work table 31 is loaded in the dryer. (S1011).

When the loading of the tray is completed, the control device 140a counts the number of trays loaded, operates the horizontal driving unit 110 to return the guide 32 or the work table 31 to its original position, and drives the vertical driving unit 120 . to return the worktable 31 to the initial position (S1012). In this case, the return to the initial position may use the initial position detection unit 161 or may use the first distance.

Meanwhile, according to the above bar, the control device 140a has been described as setting the work start position after first setting the initial position of the work table 31, but as another embodiment, the initial position after setting the work start position first After setting, it is possible to move the work table 31 to the work start position when the second detection signal is received.

11 is a flowchart illustrating a loading operation after the initial loading operation of the lift apparatus for a dryer according to the second embodiment of the present invention. Referring to FIG. 11 , the control device 140a returns the work table 31 to the initial position after putting the tray into the set work start position in the dryer (S1101).

In this state, the operator puts the second tray on the work table, and then pushes the tray into the work table 31 after filling the drying object. Accordingly, when the tray is completely placed on the work table 31, the seating detection unit 162 detects that the tray is placed on the work table 31 and transmits a second detection signal to the control device 140a.

When the control device 140a receives the second detection signal (S1102), it determines the number of trays loaded in the dryer. Then, the control device 140a calculates the vertical movement distance corresponding to the second tray by grasping the first distance and the vertical tray interval (S1103). At this time, the calculated vertical movement distance is the result of subtracting (vertical tray interval * number of loaded trays) from the first distance. That is, "the calculated vertical movement distance = (first distance) - (vertical tray interval * the number of trays loaded)".

The control device 140a drives the vertical drive unit 120 to vertically move the work table 31 downward (S1104), and measures the vertical movement distance through the vertical movement distance measurement unit 170, and the vertical movement distance measurement unit The vertical movement distance measured in 170 is received (S1105). Then, the control device 140a determines whether the measured vertical movement distance is the same as the calculated vertical movement distance (S1106), and if different, continues to vertically move the work table 31, and if it is the same, the work table 31 is stopped (S1107) ).

In a state in which the work table 31 is stopped, the control device 140a operates the horizontal driving unit 110 to move the guide 32 in the horizontal direction or to move the work table 31 horizontally to be placed on the work table 31 . Let the tray be loaded in the dryer (S1108).

When the loading of the tray is completed, the control device 140a counts the number of trays loaded, operates the horizontal driving unit 110 to return the guide 32 or the work table 30 to its original position, and drives the vertical driving unit 120 . to return the worktable 31 to the initial position (S1109).

Next, an operation of sequentially taking out the trays in the dryer one by one will be described. The operation of taking out the trays in the dryer one by one is almost the same as the operation of loading the trays into the dryer one by one.

However, in the carrying out operation, since the process of placing the tray on the work table 31 by the operator is omitted, the process of receiving the second detection signal is omitted. In addition, the process of connecting the connecting part 34 to the tray in the dryer is added to the carrying out operation. At this time, the added process is to move the guide 32 or the workbench 30 horizontally after performing the process S1107 of FIG. It is a process of connecting to the , a process of horizontally moving the guide 32 or the worktable 30 to return to its original position, and a process of returning the workbench 30 on which the tray is placed to the work position.

Although the embodiment of the present invention has been described in detail above, the scope of the present invention is not limited thereto, and various modifications and improvements by those of ordinary skill in the field to which the present invention pertains are also rights of the present invention. belong to the scope
