BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0011]
FIGS. 1 to 3 are views showing an embodiment of a tray transport device according to the present invention.
[0012]
As shown in FIGS. 1 and 3, the tray transport device 10 is installed between a dining room and a dishwashing area, and the tray transport device 10 transports a tray T on which empty dishes c are placed. ing.
[0013]
Such a tray transport device 10 is provided on the cafeteria side and has an upper conveyor 11 having a placing portion 11a and an accumulating portion 11b, a lower stopper 17 provided below the upper conveyor 11 and provided on the washing place side. , A roller conveyor 16 provided between the upper conveyor 11 and the lower stopper 17.
[0014]
Among them, the upper conveyor 11, the roller conveyor 16, and the lower stopper 17 are accommodated in a stainless steel cover 20. A fixed mounting table 26 made of stainless steel is provided at the tip of the mounting portion 11a of the upper conveyor 11 adjacent to the mounting portion 11a. The fixed mounting table 26 is also stored in the cover 20 and is held on the inner surface of the cover 20.
[0015]
In addition, the tray user places the tray T on which the empty tableware c is placed on the mounting portion 11a and the fixed mounting table 26 of the upper conveyor 11. In this case, a mark serving as a mark is provided on the fixed mounting table 26 so that half of the tray T is mounted on the mounting portion 11a and the other half of the tray T is mounted on the fixed mounting table 26. Further, as the upper conveyor 11 is driven, the tray T placed on the placing section 11a and the fixed placing table 26 is sent to the stacking section 11b.
[0016]
Further, the lower stopper 17 is directed to the washing place through the opening 20b on the washing place side. Therefore, the trays T accumulated in the lower stopper 17 are drawn into the washing place by the operator through the opening 20b. I have.
[0017]
Note that the cover 20 is fitted into a wall W provided upright on the floor F, and the surface on the dining room side of the cover 20 is flush with the surface of the wall W.
[0018]
The cover 20 is open at the bottom.
[0019]
Next, the upper conveyor 11 will be described in detail. The upper conveyor 11 includes a pair of side plates 12, 12 supported on a floor F via support rods 18, a driven shaft 14 and a drive shaft 15 attached to the pair of side plates 12, 12, and a pair of driven shafts 14. And a belt 13 stretched between the drive shaft 15.
[0020]
Of these, the support rod 18 and the pair of side plates 12, 12 are made of stainless steel, and the belt 13 is made of a synthetic resin, for example, urethane rubber.
[0021]
Further, a drive control unit 25 is connected to the drive shaft 15, and a sensor 19 for detecting a tray T on which an empty tableware c is placed is provided near the placement unit 11 a of the upper conveyor 11.
[0022]
The sensor 19 is connected to a drive control unit 25, and the drive control unit 25 drives the upper conveyor 11 by operating the drive shaft 15 based on a signal from the sensor 19, and the mounting unit 11 a of the upper conveyor 11 and the fixed mounting The tray T on the table 26 is sent to the stacking unit 11b, and the tray T on the stacking unit 11b is sent from the roller conveyor 16 to the lower stopper 17 side. The upper conveyor 11 as a whole slightly rises from the placing section 11a toward the stacking section 11b.
[0023]
The roller conveyor 16 has a number of rotatable rollers 16a, and the roller conveyor 16 is entirely made of stainless steel. For this reason, the tray T sent to the roller conveyor 16 falls on the rollers 16a of the roller conveyor 16 by its own weight.
[0024]
Further, the lower stopper 17 is also made of stainless steel, and the tray T on the lower stopper 17 is drawn into the washing place side from the opening 20b of the cover 20, and is once placed on the mounting table 23 in the washing place. The leftovers of the tableware c on the tray T are discharged into the discharge port 22, and the tableware c is washed in the sink 21.
[0025]
The upper conveyor 11, the lower stopper 17, and the roller conveyor 16 may be provided in the cover 20 in a pair in the vertical direction.
[0026]
Next, the operation of the present embodiment having such a configuration will be described.
[0027]
After the meal in the cafeteria is completed, the tray user places the tray T on which the empty tableware c is placed on the mounting portion 11a of the upper conveyor 11 and the fixed mounting table 26. In this case, the tray T is placed according to the mark on the fixed mounting table 26, and half of the tray T is placed on the mounting portion 11a, and the other half is mounted on the fixed mounting table 26.
[0028]
When the sensor 19 detects that the tray T has been placed on the placement unit 11a and the fixed placement table 26, a signal from the sensor 19 is sent to the drive control unit 25. The drive control unit 25 operates the drive shaft 15 based on a signal from the sensor 19. As a result, the belt 13 of the upper conveyor 11 is driven, and the tray T on the mounting portion 11a and the fixed mounting table 26 is pulled in by the belt 13 of the upper conveyor 11, and is sent to the stacking portion 11b. At the same time, the tray T accumulated on the accumulation section 11b of the upper conveyor 11 falls on the rollers 16a of the roller conveyor 16 by its own weight, and is sent to the lower stopper 17 side.
[0029]
The trays T accumulated on the lower stopper 17 and the lower part of the roller conveyor 16 are drawn into the washing place through the opening 20b on the washing place side, and the tray T and the dishes c are washed in the washing place.
[0030]
As described above, according to the present embodiment, after the meal is finished in the dining room, the tray user places the tray T on which the empty tableware c is placed on the mounting portion 11a of the upper conveyor 11 and the fixed mounting table 26. Simply by placing the tray T, the tray T can be easily and easily transported to the washing place via the upper conveyor 11, the roller conveyor 16, and the lower stopper 17.
[0031]
Further, the trays T placed on the placing section 11a of the upper conveyor 11 and the fixed placing table 26 are temporarily accumulated in the accumulation section 11b of the upper conveyor 11, so that the placing section 11a of the upper conveyor 11 and the fixed placing table The tray 26 can always be left empty, and the tray user can easily place the tray T on the mounting portion 11a and the fixed mounting table 26. In addition, by leaving the mounting portion 11a and the fixed mounting table 26 empty, the appearance on the dining room side can be kept good.
[0032]
Further, since the upper conveyor 11 rises from the mounting portion 11a toward the stacking portion 11b, the drop height of the roller conveyor 16 from the stacking portion 11b to the lower stopper 17 can be increased, and the roller conveyor 16 The tray T can be easily and reliably dropped and transported along its own weight.
[0033]
Further, the trays T on the upper conveyor 11 are temporarily accumulated on the lower stopper 17 via the roller conveyor 16, so that a large amount of trays T are not supplied to the washing place at the same time.
[0034]
【The invention's effect】
As described above, according to the present invention, simply by placing a tray on the placement section of the upper conveyor, the tray is temporarily accumulated in the accumulation section of the upper conveyor, and then easily moved to the lower stopper side via the roller conveyor. And can be sent reliably. In addition, since the mounting portion of the upper conveyor can always be emptied, the tray can be easily mounted on the mounting portion, and the appearance of the upper conveyor side can be kept good.
