[ The cover 111 is provided at the top of the open front of the storage unit 110 and supports the trays located at the top of the storage unit 110. Therefore, the cover 111 prevents the trays located at the upper end of the receiving part 110 from being separated from the receiving part 110.

The receiving portion 110 has a pair of grooves 112 at the upper end portions of both sides thereof. The picker can easily pick up the trays of the storage unit 110 through the grooves 112. [

The elevating part 120 supports the trays of the receiving part 110 and raises the trays so that the picker can pick up the trays through the upper surface.

The lifting unit 120 includes support bars 121, a guide member 122, a connection plate 123, and a first driver 124.

The support bars 121 support the trays. For example, the support bars 121 support the lower surface of the lowermost tray among the trays vertically stacked in the internal space of the storage unit 110. [ At least four support bars 121 may be provided to stably support the trays. For example, four support bars 121 may be provided to support the four corners of the lowermost tray.

The opening and closing part 150 selectively opens and closes the front surface of the storage part 110 and includes a pair of shutters 151 and third drivers 152 for moving the shutters 151 do.

The shutters 151 are disposed adjacent to the front surface on both sides of the receiving part 110 and extend in the vertical direction. At this time, the shutters 151 may be positioned between the height of the transfer unit 140 and the height of the cover 111. [ The shutters 151 can move between the front surface of the storage unit 110 and the both side surfaces. The shutters 151 open the front surface while the trays are supplied to the inside of the receiving part 110 and the trays are released from the inside when the feeding of the trays to the inside of the receiving part 110 is completed The front surface is cut off.

The third actuators 152 are provided on both sides of the storage part 110 and move the shutters 151 between the front surface of the storage part 110 and the both side surfaces.

Therefore, the opening / closing part 150 and the cover 111 prevent the trays in the receiving part 110 from being separated from the receiving part 110. [

The sensing unit 160 senses the height of the elevating unit 120 and includes a fixing member 161, a first sensor 162 and a second sensor 163.

The first sensor 162 senses an upper limit of the lifting unit 120 and the second sensor 163 senses a lower limit of the lifting unit 120. [ For example, when the first sensor 162 detects the connection plate 123, an upper end of the support bars 131 is the same height as the upper surface of the buffer unit 130 or the buffer unit 130. It may be slightly higher than the top of. When the second sensor 163 detects the connection plate 123, an upper end of the support bars 131 is positioned at the same height as the upper surface of the transfer unit 140 or slightly lower than an upper surface of the transfer unit 140. can do.

Therefore, the ascending and descending range of the lifting unit 120 can be accurately confirmed using the sensing unit 160. [ Therefore, it is possible to prevent the lifting unit 120 from being raised or lowered excessively.

The tray feeding apparatus 100 can quickly and stably supply the trays so that the picker can continuously convey the trays without waiting time.

3 to 6 are front views for explaining a tray feeding method using the tray feeding apparatus shown in FIG.

Referring to FIG. 3, the elevation part 120 is lowered so that the second sensor 163 detects the connection plate 123. Therefore, the upper ends of the support bars 131 may be positioned at the same height as the upper surface of the transfer unit 140 or slightly lower than the upper surface of the transfer unit 140.

Further, the shutters 151 are moved to both sides of the storage unit 110 so that the opening / closing unit 150 opens the front surface of the storage unit 110.

The trays stacked in the vertical direction are transported from the outside of the storage unit 110 to the transport unit 140 in a state in which the lifting unit 120 descends and the opening and closing unit 150 opens the front surface of the storage unit 110. [ The conveyor belts 141 are rotated so that the trays can be transferred to the inside of the receiving part 110 from the front surface of the receiving part 110. [ The transfer unit 140 can automatically transfer the trays to the inside of the storage unit 110 without an operator, so that the tray can be transferred quickly and stably.

4, when the trays are transported to the inside of the storage unit 110, the shutters 151 are moved to the front surface of the storage unit 110 so that the opening and closing unit 150 is moved to the storage unit 110, The front surface of the main body is cut off. Therefore, it is possible to prevent the trays in the storage unit 110 from being separated from the front surface of the storage unit 110.

Then, the lift unit 120 sequentially raises the trays in the storage unit 110 so that the picker can pick up the uppermost tray through the upper surface of the storage unit 110. At this time, the buffer unit 130 is pushed up by the trays by the force of the lifting unit 120 to raise the trays to release the horizontal state, or the horizontal plate of the buffer unit 130 It is possible to maintain a state in which it is not protruded toward the inside of the accommodating portion 110. [

Referring to FIG. 5, the first sensor 162 raises the elevation portion 120 to sense the connection plate 123. Therefore, the lifting unit 120 is positioned at a constant height, that is, the upper end of the support bars 131 is the same height as the upper surface of the buffer unit 130 or slightly higher than the upper surface of the buffer unit 130. Therefore, the buffer unit 130 can support the trays supported by the lifting unit 120. The trays are removed by the force of pushing up the buffer unit 130 so that the buffer unit 130 supports the trays while maintaining a plurality of horizontal states or the horizontal plate of the buffer unit 130 is supported by the receiving unit 110 So as to support the trays.

The buffer unit 130 may support a plurality of trays by a height from the upper surface of the buffer unit 130 to the upper end of the storage unit 110. Therefore, the picker can pick up the trays supported by the buffer unit 130 without waiting time while the lifting unit 120 descends to accommodate new trays into the storage unit 110. [ However, since the buffer unit 130 does not lift the trays but only raises the trays, the picker must descend gradually to pick up the tray.

Referring to FIG. 6, the buffer 130 supports the trays supported by the lifting unit 120, so that the lifting unit 120 is lowered to accommodate new trays into the storage unit 110 . The lifting unit 120 is lowered until the second sensor 163 detects the connection plate 123.

3 to 6 are fed into the receiving part 110, the trays are raised by the elevating part 120, the trays are supported by the buffer part 130, And the step of lowering the part 120 is repeated.

The picker picks up the trays held in the buffer unit 130 until the new trays are fed into the receiving unit 110 and the elevator unit 120 raises the new trays. Thus, the tray feeding method can supply the tray so that the picker picks up the trays without delay.

As described above, the tray feeding apparatus and method according to the present invention can support existing trays while the new trays are being fed to the receiving section. Therefore, the picker can continuously transport the tray without waiting time.

In addition, since the conveying section supplies the trays to the receiving section, the trays can be supplied quickly and stably.

Therefore, productivity and reliability of the tray feeding process can be improved.
