DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. In the drawings for explaining the embodiment, the same components are generally designated by the same reference numerals, and the repeated description will be omitted.

[0018] FIG. 1 is an oblique view showing a prepared food supply system which is one embodiment of the present invention, FIG. 2 is an oblique view showing a container removal device, a prepared food serving device and a container conveying table which constitute the prepared food supply system of FIG. 1, and FIG. 3 is an oblique view showing a transfer device which constitutes the prepared food supply system of FIG. 1 together with the container conveying table.

[0019] 1, the prepared food supply system of this embodiment is composed of a container removal device (container removal means) 10 that removes the bottommost container B one by one from a container stack BT in which containers (small bowls, plates, bowls, etc.) B are stacked, a turntable-type container transport table (transport means) 11 that intermittently transports the containers B removed from the container removal device 10, a prepared food serving device (prepared food serving means) 30 that serves weighed prepared food in the container B transported to the container transport table 11 as prepared food (e.g., boiled food, steamed food, grilled food, fried food, mixed food, salads, etc.) is introduced, and a transfer device (transfer means) 20 that transfers the container B transported to the container transport table 11 after the prepared food has been served onto it to a tray 24. The container removal device 10, the container transport table 11, and the prepared food serving device 30 are installed on a stage 13. As shown in the figure, the stage 13 and the transfer device 20 are mounted side by side on a caster frame 14 having casters 14a attached to the four corners for freedom of movement.

[0020] As shown in FIG. 2, the container removal device 10 includes a base body 10a having an opening (not shown). A container storage section 12 is provided above the opening, in which containers B are stacked and stored as a container stack BT. A pair of first moving claws (a pair of first moving members: not shown) that can move toward and away from each other are provided on either side of the opening, and a pair of second moving claws (a pair of second moving members) 17 that can also move toward and away from each other are provided above the pair of first moving claws. A pair of guide blocks 15 are provided on both sides of the pair of first moving claws and the pair of second moving claws 17 to support the pair of first moving claws and the pair of second moving claws 17 and guide their movement.

[0021] In addition, guide rods 12a that contact the sides of the container stack BT and support it are installed in the container storage section 12 facing the up and down direction. As shown in the figure, a total of four guide rods 12a are arranged on each of a pair of moving claws (a pair of first moving claws and a pair of second moving claws), two on each side, and are attached to a rod plate 16 provided below the pair of first moving claws. This rod plate 16 is supported by the above-mentioned guide block 15 and can move toward and away from each other so as to support container stacks BT of various widths. Note that, for convenience in stacking the containers B, the height of the guide rod 12a on the front side is lower than that of the guide rod 12a on the back side. However, the number of guide rods 12a may be more than one, and it is not necessary to have four as shown in this embodiment as long as the container stack BT can be supported without falling over.

[0022] Here, the pair of first movable claws can be moved between a holding position where they approach each other to hold the bottom container B, which is the container B located at the bottom of the container stack BT, and a release position where they move away from each other to release the hold of the bottom container B. The pair of second movable claws 17 can be moved between a release position where they move away from each other to release the hold of the directly above container B (the container stacked directly above the bottom container) when the pair of first movable claws are in the holding position, and a holding position where they approach each other to hold the directly above container B when the pair of first movable claws are in the release position. Therefore, the action (approaching action and separating action) of these two pairs of movable claws supports the container stack BT from below, and the bottom container B is separated.

[0023] In addition, directly below the container storage section 12, a lifting member (not shown) is provided which can be raised and lowered to support the bottom surface of the released bottom container B, remove the bottom container B from the container stack BT, and load it onto the container transport table 11.

[0024] As shown in FIG. 2, the container transport table 11 has a lifting member that moves in and out, and holding holes 11a formed at regular intervals in the circumferential direction into which the bottommost container B removed by the lifting member fits and is held.

[0025] The prepared food serving device 30 is structured so that prepared food put into a hopper 31 is loosened by a loosening mechanism 32, sent downward, and measured to a predetermined amount in a measuring and supply cup 33 that can be opened and closed so as to open downward, and then dropped and supplied to a container B on a container conveying table 11 located directly below. In Fig. 2, the hopper 31 is composed of an upper frame 31a and a main body portion 31b into which the upper frame 31a is fitted and which is integrated with the loosening mechanism 32. Details of the prepared food serving device 30 will be described later.

[0026] 1 and 3, the transfer device 20 includes a transfer unit 22 on which a gripper 21 for gripping and releasing a container B is mounted so as to be capable of ascending and descending, and a reciprocating unit 23 on which the transfer unit 22 is installed so as to be capable of linearly reciprocating. The container B is transferred onto a tray 24 installed on the transfer device 20 by the transfer unit 22. That is, the transfer unit 22 moving on the reciprocating unit 23 grips the container B with the gripper 21 at one end of movement (the position of the container B (container B with prepared food served on it) transported by the container transport table 11 described above) and moves upwards in a linear manner, and at the other end of movement (the position of the container B on the tray 24) the gripper 21 is lowered to transfer the container B onto the tray 24.

[0027] As shown in FIG. 3, the gripping portion 21 is provided with a pair of gripping bodies 21a, 21a that can move horizontally between a gripping position where they approach each other to grip the container B and a release position where they move away from each other to release the grip of the container B, and the container B is gripped and released as the pair of gripping bodies 21a, 21a approach and move away from each other.

[0028] The transfer device 20 also includes a tray moving conveyor (moving section) 25 that intermittently moves the above-mentioned tray 24 in a direction intersecting with the moving direction of the transfer section 22. In this embodiment, support rails 26 are provided on both sides of the tray moving conveyor 25 to support both sides of the tray 24 moved by the tray moving conveyor 25. The support rails 26 prevent the tray 24 from becoming unstable on the tray moving conveyor 25 due to poor weight balance in the front-rear and left-right directions when the container B is loaded onto the tray 24. However, if the width of the tray moving conveyor 25 is sufficiently wide relative to the tray 24 and there is no concern about poor weight balance, the support rails 26 can be omitted.

[0029] Then, if containers B are transferred onto tray 24 so that they are lined up in a row along the movement direction of transfer section 22 while the movement of tray 24 by tray moving conveyor 25 is stopped, tray 24 is moved by one row of containers B and stopped, and then transfer section 22 and tray moving conveyor 25 operate to transfer containers B onto tray 24 again so that they are lined up in a row along the movement direction of transfer section 22.

[0030] Next, the prepared food serving device 30 will be described with reference to Figures 4 to 8. Here, Figure 4 is a perspective view of the prepared food serving device constituting the prepared food supply system of this embodiment, excluding the measuring and supply cup, Figure 5 is a perspective view of the prepared food serving device of Figure 4 seen from above, Figure 6 is a perspective view showing the measuring and supply cup with the front cover of the unwinding mechanism constituting the prepared food serving device of Figure 4 removed, Figure 7 is a perspective view showing the unwinding mechanism constituting the prepared food serving device of Figure 4 from the opposite side to Figure 6 with the front cover removed, and Figure 8 is a left side view showing the unwinding mechanism constituting the prepared food serving device of Figure 4 with the front cover removed.

[0031] The prepared food serving device 30 is composed of a hopper 31 consisting of an upper frame 31a (Figure 2) and a main body 31b, into which the prepared food is put, a loosening mechanism 32 which loosens the prepared food put into the hopper 31 and sends it downward, and a measuring and supply cup 33 which can be opened and closed so as to open downward, measures out a predetermined amount of prepared food and drops it into container B on the container conveying table 11 located directly below.

[0032] As shown in Figures 4 and 5, the hopper 31 integrated with the unwinding mechanism 32 (more specifically, within the main body 31b of the hopper 31) is equipped with a conveying screw 34 that conveys the added prepared food toward the unwinding mechanism 32 located downstream in the conveying direction, and a reverse screw 35 that returns prepared food that is unable to reach the unwinding mechanism 32 by the conveying screw 34 to the upstream side in the conveying direction.

[0033] 5, a substantially semicircular storage groove 36 is formed in the center of the inner bottom surface of the hopper 31 so as to extend toward the unwinding mechanism 32, and the aforementioned conveying screw 34 is disposed in the storage groove 36. In addition, the reverse screws 35 are disposed on both sides of the conveying screw 34 at positions higher than the storage groove 36.

[0034] Here, the conveying screw 34 is composed of a shaft 34a which is a rotating shaft, and a spiral blade 34b formed around the shaft 34a. The reverse screw 35 is composed of a shaft 35a which is a rotating shaft, a spiral blade 35b which is formed on the shaft 35a on the downstream side in the conveying direction and which faces in the opposite direction to the spiral blade 34b of the conveying screw 34, and a plate 35c which is formed along the shaft 35a on the upstream side in the conveying direction and which sends the prepared food returned by the spiral blade 35b into the storage groove 36 in which the conveying screw 34 is arranged.

[0035] In this embodiment, two reverse screws 35 are arranged on both sides of the conveying screw 34, but one may be used. The shapes of the conveying screw 34 and the reverse screw 35 are not limited to this embodiment. In other words, various shapes can be adopted for the conveying screw 34 as long as it can convey the prepared food toward the loosening mechanism 32, and for the reverse screw 35 as long as it can return the prepared food that could not reach the loosening mechanism 32 to the upstream side in the conveying direction.

[0036] As shown in FIGS. 4 and 5, the unwinding mechanism 32 includes a housing 32a that is composed of a cover main body 32aa attached to the hopper 31 and a front cover 32ab that is detachably attached to the cover main body 32aa.

[0037] 6 to 8, upper and lower two-stage loosening rollers 37 for loosening and sending the prepared food conveyed by the conveying screw 34 downward are rotatably provided in the housing 32a with both ends supported by the housing 32a. As shown in the figures, these loosening rollers 37 include a roller main body 37a and multiple loosening blades 37b provided in the radial direction of the roller main body 37a. The prepared food is loosened and sent downward by the multiple loosening blades 37b rotating around the roller main body 37a.

[0038] A gear 38 having many teeth formed on its outer circumference is attached to one end of the roller body 37a. The gear 38 attached to the upper roller body 37a and the gear 38 attached to the lower roller body 37a are gear-coupled via an idle gear 39. This allows the upper and lower unwinding rollers 37 to rotate in the same direction. An endless belt may be stretched between the upper and lower gears 38 to rotate them in the same direction.

[0039] A transmission gear 42 to which driving force from a motor (not shown) is transmitted is attached to the end opposite to the gear 38 of the roller body 37a constituting the lower unwinding roller 37. Therefore, in this embodiment, the lower unwinding roller 37 is the driving side, and the upper unwinding roller 37 is the driven side that rotates with the rotation of the lower unwinding roller 37.

[0040] In addition, the diameter of the upper gear 38 is larger than that of the lower gear 38, so that the rotation speed of the upper loosening roller 37 is set to be slower than that of the lower loosening roller 37. As a result, the prepared food in the hopper 31 conveyed by the conveying screw 34 is scraped in large quantities by the upper loosening roller 37 and loosened, and the prepared food scraped in by the upper loosening roller 37 is further finely broken down by the lower loosening roller 37, after which it is measured in the measuring and supply cup 33.

[0041] As shown in Fig. 6, the measuring and supplying cup 33 provided immediately below the unwinding mechanism 32 can be opened and closed so as to open downward as described above. That is, the measuring and supplying cup 33 is composed of two cup pieces 33a and 33b divided into left and right, and has an inverted triangular shape when viewed from the front. Each cup piece 33a and 33b is fitted with a pivot 40 (the cup piece 33b side is not shown) for opening and closing the measuring and supplying cup 33 by pivoting the cup pieces 33a and 33b, respectively. Furthermore, the prepared food serving device 30 is provided with a load cell 41 for weighing prepared food with the measuring and supplying cup 33 in the closed position.

[0042] Therefore, in the measuring and supply cup 33, the side dish loosened by the loosening mechanism 32 is weighed by the load cell 41 when the pivot shaft 40 is in the closed position, and when the specified set weight is reached, the pivot shaft 40 is rotated to the open position and the side dish is dropped and supplied into container B on the container conveying table 11 located directly below.

[0043] In the above description, the loosening rollers 37 are arranged in two vertical stages so that they can rotate in the same direction, but this is not limited to two vertical stages, and may be one stage or three or more vertical stages. In addition, the loosening rollers 37 may have various shapes as long as the roller body 37a is provided with loosening blades 37b for loosening the side dishes.

[0044] As an example, an unraveling mechanism 32 in which unraveling rollers 37 are arranged in only one stage will be described with reference to Figures 9 to 11. Here, Figure 9 is a perspective view showing the unraveling mechanism constituting the prepared food serving device as a modified example of this embodiment with its front cover removed and without the measuring and supply cup, Figure 10 is a perspective view showing the unraveling rollers attached to the prepared food serving device of Figure 9, and Figure 11 is a front view of Figure 10.

[0045] As shown in these drawings, the roller body 37a of the unwinding roller 37 arranged in the unwinding mechanism 32 has a smallest diameter in the axial center and gradually becomes larger toward both sides. In addition, flanges 37c are formed on both ends of the roller body 37a to prevent the prepared food from protruding from both ends of the roller body 37a and getting between the roller body 37a and the housing 32a. Furthermore, the peripheral surface of the roller body 37a is embossed to prevent the prepared food from adhering.

[0046] The diameter of roller body 37a of unwinding roller 37 shown in Figures 9 to 11 is larger overall than the diameter of roller body 37a of unwinding roller 37 shown in Figures 6 to 8 described above. Moreover, the length of multiple unwinding blades 37b provided on roller body 37a of unwinding roller 37 shown in Figures 9 to 11 is conversely shorter than the length of multiple unwinding blades 37b of unwinding roller 37 shown in Figures 6 to 8.

[0047] As described above, the prepared food supply system of this embodiment is composed of a container removal device 10 that removes the bottommost container B one by one from a container stack BT in which containers B are stacked, a container transport table 11 that carries and intermittently transports the containers B removed from the container removal device 10, a prepared food plating device 30 that receives the prepared food and plates the weighed prepared food into the container B transported to the container transport table 11, and a transfer device 20 that transfers the container B after the prepared food has been plated and transported to the container transport table 11 to a tray 24.

[0048] Therefore, by simply stacking the containers B in the container removal device 10 and loading the cooked side dishes into the side dish plating device 30, it is possible to automatically perform operations from supplying the containers B to plating a fixed amount of the side dishes and transferring them to the tray 24.

[0049] The invention made by the inventor has been specifically described above based on the embodiment, but the embodiment disclosed in this specification is illustrative in all respects and is not limited to the disclosed technology. In other words, the technical scope of the present invention should not be interpreted restrictively based on the description in the above embodiment, but should be interpreted strictly according to the description in the claims, and includes technologies equivalent to the described technologies in the claims and all modifications that do not deviate from the gist of the claims.

[0050] For example, in this embodiment, two types of loosening rollers (loosening roller 37 shown in Figs. 6 to 8 and loosening roller 37 shown in Figs. 6 to 8) are disclosed, but since the ease of loosening varies depending on the type of prepared food, such as the type of ingredients used, the cutting size, and the cooking method, it is desirable to determine the number of stages of loosening roller 37, the shape of roller main body 37a, the number and shape of loosening blades 37b, etc., depending on the type of prepared food. Therefore, the two types of loosening rollers 37 shown in this embodiment are merely examples, and are not limited to these.

[0051] In addition, in this embodiment, a belt-type conveyor called the tray moving conveyor 25 is used as the moving part for the tray 24, but it is sufficient if the tray 24 can be moved intermittently by one row of containers at a time, and it may be moved by, for example, a roller-type conveyor. [Industrial Applicability]

[0052] In the prepared food supply system described above, the type of prepared food that is put into the container is not particularly limited, and this prepared food supply system can be used for various prepared foods that can be put into a container. [Explanation of symbols]
