  Hereinafter, the present invention will be described in detail with reference to the drawings, but the present invention is not limited to the illustrated one. Moreover, although a rice cooker is used as a cooking container and a rice cooking system is used as an example of a heating cooking system, the cooking container targeted by the present invention is not limited to the rice cooking pot, and the heating targeted by the present invention. The cooking system is not limited to the rice cooking system.

  FIG. 1 is a side view showing an example of a rice cooker transport device as a cooking container transport device of the present invention. In FIG. 1, 1 is the rice cooker conveyance apparatus of this invention, 2 is the rice cooker which is a conveyance target object. Reference numerals 3 and 3 denote gripping claws that can be gripped / opened by expanding or contracting outward by a drive device (not shown). Reference numeral 4 denotes a gripping part including gripping claws 3 and 3, and the gripping part 4 is coupled to an elevating part 5 that can lift and lower the gripping part 4. A traveling unit 6 is a traveling unit that can cause the gripping unit 4 and the lifting unit 5 to travel along a predetermined route.

  The elevating unit 5 is provided with an elevating motor 7, and the elevating unit 5 performs an elevating operation by a driving force generated by the elevating motor 7. It can be raised and lowered in the direction. On the other hand, the traveling unit 6 includes a traveling motor 8, and the traveling unit 6 rotates the traveling wheels 9 and 9 by a driving force generated by the traveling motor 8, and is guided by the rail 10. It can move forward and backward freely in the horizontal arrow direction in the figure. In the illustrated example, the rail 10 is positioned below the traveling unit 6, but the rail 10 may be positioned above the traveling unit 6 and the traveling unit 6 may be suspended from the rail 10. Further, the power source for raising and lowering the elevating unit 5 is not limited to the elevating motor, and an actuator that operates with a fluid pressure such as gas or liquid can also be used.

  11 is a shutter, 12 is a shutter driving motor, 13 is a gripping / releasing operation of the gripping portion 4, a lifting / lowering operation of the lifting / lowering portion 5, a traveling operation of the traveling portion 6, a driving operation of the shutter 11 and the like. It is a control device. The power source for moving the shutter 11 is not limited to the shutter driving motor, and it is of course possible to use an actuator that operates with fluid pressure such as gas or liquid.

  The electric power used for the various mechanical operations and controls described above in the rice cooker transport apparatus 1 of the present invention can be supplied from an overhead wire (not shown) via a current collector (not shown), for example. In some cases, a power supply device such as a storage battery or a fuel cell may be mounted on the traveling unit 6 to supply power by the power supply device.

  A plurality of rice cooking units 14, 14, 14... Are arranged in a row below the rail 10, and together with the rice cooker transport device 1 of the present invention disposed above the rice cooking units 14, 14, 14. This is a rice cooking system. The rice cooker transport apparatus 1 of the present invention shows a rice cooker 2 that has been transported along another transport line (not shown) after the gripping portion 4 is lowered and gripped by the gripping claws 3 and 3, for example, as shown by a solid line in the drawing. As described above, in a state where it is lifted up to a predetermined position, it travels back and forth on the rail 10, stops on an appropriate rice cooking unit 11, lowers the grip portion 4 to the position indicated by the broken line in the figure, and It can be installed in the rice cooking unit 11. Moreover, the rice cooker 2 installed in the rice cooking unit 11 is gripped by the gripping claws 3 and 3, the lifting unit 5 is operated to raise the rice cooker 2 together with the gripping unit 4 to the solid line position in the figure, and in this state It is also possible to travel back and forth on the rail 10 and transport, for example, to an appropriate position downstream of a transport line (not shown). Thus, according to the rice cooking system of this invention, acceptance of the rice cooking pot 2 from outside the system system, installation to the rice cooking unit 14 as appropriate, removal of the rice cooking pot 2 from the rice cooking unit 14, and removal from the system system A series of operations such as unloading can be performed efficiently. And since a rice cooker conveyance apparatus can be located on a rice cooking line, there exists an advantage that space saving can be implement | achieved.

  In addition, the rice cooking unit is a unit that is equipped with appropriate heating means, a control device, a sensor and the like so that the rice cooker 2 can be heated and cooked, and can be cooked individually. When it is not specialized in cooking rice, it should be called a cooking unit.

  FIG. 2 is a side view of the shutter 11 and its structure, as seen from the left direction from the line AA in FIG. 1, and the same members as those in FIG. is there. As shown in FIGS. 1 and 2, in the illustrated example, the shutter 11 has a shape obtained by cutting a part of a cylinder in a vertical direction along the axis of the cylinder, and through a shutter support member 15, It is rotatably held around the rotary shaft 16. Since the rotation shaft 16 does not exist on the shutter 11, when the shutter 11 is rotated around the rotation shaft 16, the shutter 11 draws an arcuate rotation locus. The position indicated by the broken line in the figure is the closing position where the shutter 11 is at the lowest point of the arcuate rotation locus, and the position indicated by the solid line is approximately 90 degrees from the lowest point of the arcuate rotation locus. It is a retreat position that is raised by an angle. In the illustrated example, the rotating shaft 16 is in a horizontal direction parallel to the traveling direction of the rice cooker transport device 1, but the rotating shaft 16 may be in a horizontal direction orthogonal to the traveling direction of the rice cooker transport device 1. good.

  Note that the closing position of the shutter 11 is not necessarily the lowest point of the arcuate rotation trajectory, and as will be described later, it is possible to prevent the fallen object from falling by covering the grip 4 from below. As long as the position is possible, it may be shifted from the lowest point. Similarly, the retracted position of the shutter 11 does not necessarily have to be raised by an angle of approximately 90 degrees from the lowest point, and may be a position that does not hinder the lifting and lowering operation of the grip portion 4 as will be described later. It may be a position raised by an angle of less than 90 degrees from the lowest point or a position raised by more than 90 degrees from the lowest point.

  Further, in the example shown in the figure, the shutter 11 is a plate-like member having a shape obtained by cutting a part of a cylinder in the vertical direction along the axis of the cylinder. However, the shutter 11 has a thinner sheet shape. It is also possible to use a mesh or mesh, and it is not always necessary to be an integral member as a whole, and multiple types of materials can be stacked, bonded, added, and stretched to maintain the shape. You may be comprised from the passed flexible member. The material constituting the shutter 11 is not particularly limited, and metals such as stainless steel, steel, iron, copper, and aluminum, processed products thereof, paper, plastic, wood, etc. can be used in combination with a framework that maintains the shape. When used, a flexible material such as woven fabric, non-woven fabric, or vinyl can also be used. However, since it is used for the apparatus which conveys a cooking container like a rice cooker, it is preferable to use metals, such as stainless steel and aluminum.

  Next, operation | movement of the rice cooker conveying apparatus 1 of this invention is demonstrated using FIGS. 3 to 7 are left side views of FIG. 1, but only necessary members are shown for convenience of explanation.

  FIG. 3 shows an initial state, where the grip portion 4 is in the raised position, and the shutter 11 is in the closed position. In this state, a shutter closing signal is issued, and the control device 13 provided in the rice cooker transport device 1 gives a running permission to the running unit 6 and gives a lowering prohibition command to the lifting unit 5. ing. The shutter closing signal operates when the shutter 11 reaches a predetermined closing position or exists at a predetermined closing position, for example, using a sensor such as a non-contact type optical sensor or a contact type mechanical sensor. It is also possible to emit a signal, or a signal about a rotation angle position emitted from an encoder attached to a rotating shaft 16 that rotates the shutter 11 may be used as a shutter closing signal. The shutter closing signal may be a signal that is issued only when the shutter 11 reaches the closing position, but is a signal that is issued while the shutter 11 is in the predetermined closing position. Is more safe and preferred.

  The control device 13 provided in the rice cooker transport device 1 confirms the presence of the shutter closing signal, gives the travel unit 6 permission to start travel, and the rice cooker transport device 1 travels on the rail 10. At this time, since the shutter 11 is in a closed position that covers the grip portion 4 from below, even if oil, dust, dust, water droplets, or the like fall from the grip portion 4 or the lifting portion 5, for example, it is received by the shutter 11. It does not fall on the rice cooking unit 14 located below. The same applies when a part of the mechanical parts constituting the grip part 4 and the lift part 5 falls. Therefore, the rice cooker 2 installed in the rice cooker line which consists of the row | line | column of the rice cooking unit 14, and the appropriate location of the rice cooker line can avoid the risk of suffering pollution, damage, operation trouble, etc. Note that the shutter 11 covers the grip part 4 from below means that the fallen objects from the grip part 4 and the lift part 5 do not fall below it as described above. The cover range by the shutter 11 is not particularly limited, and it is of course preferable that the cover range is wider. However, oil, dust, dust, water droplets, mechanical parts, etc. are best avoided on the rice cooker 2. Therefore, it is desirable that the shutter 11 has a size that covers at least the entire upper portion of the rice cooker 2.

  When the rice cooker transport device 1 comes on the rice cooking unit 14 in which the rice cooker 2 to be transported is accommodated, the traveling unit 6 stops. Where the rice cooker transport device 1 is stopped is a control device provided in the rice cooker transport device 1 by receiving a rice cooking end signal issued from the rice cooking unit 14 by wireless or wired, directly or via a control device (not shown). 13 may make an independent determination, or may be instructed wirelessly or by cable from a control device or a portable control terminal (not shown). Further, based on a predetermined time sequence, the control device 13 provided in the rice cooker transport device 1 may independently determine, or the stop position is instructed from a control device or a portable control terminal (not shown). You may make it do.

  Next, as shown in FIG. 4, when the rice cooker transport device 1 stops at a predetermined position, a traveling unit stop signal is issued. There is no particular limitation on the means for issuing the traveling unit stop signal, and by appropriate means, for example, the power supply to the traveling motor 8 is stopped, the rotation of the wheels 9 and 9 is stopped, the position coordinates of the rice cooker transport device 1 are A traveling unit stop signal can be issued by detecting a change stop or the like.

  When the traveling unit stop signal is issued, the control device 13 provided in the rice cooker transport device 1 gives the shutter 11 permission to move from the closed position to the retracted position, operates the shutter drive motor 12, and releases the shutter. 11 is moved from the closed position to the illustrated retracted position. As a result, the shutter 11 is not removed from the lifting path of the gripper 4 and does not obstruct the lifting operation of the gripper 4. When the shutter 11 reaches the retracted position, a shutter retract signal is issued. Similarly to the shutter closing signal, the shutter evacuation signal operates when the shutter 11 reaches a predetermined evacuation position or exists at the predetermined evacuation position, for example, a non-contact type optical sensor or a contact type It is also possible to use a sensor such as a mechanical sensor, or a signal about a rotation angle position emitted from an encoder attached to a rotary shaft 16 that rotates the shutter 11 may be used as a shutter retract signal. The shutter retract signal may be a signal that is issued only when the shutter 11 reaches the retract position, but is a signal that is generated while the shutter 11 is in the predetermined retract position. Is more safe and preferred.

  Subsequently, as shown in FIG. 5, when the presence of the shutter evacuation signal is confirmed, the control device 13 provided in the rice cooker transport device 1 gives the lifting unit 5 permission to start the lifting operation, and the lifting unit drive motor 7 is driven to lower the elevating part 5 together with the grip part 4 to a predetermined position. The lowering position of the gripping part 4 can be detected by a non-contact type optical sensor, a contact type mechanical sensor, or the like, and the vertical part coordinates and the reading device thereof are provided on the lifting part 5. The vertical position 4 may be directly detected. Based on the signal from the descending position detecting means of the gripping part 4, for example, when the elevating part 5 and the gripping part 4 are in a state of being lowered from a predetermined ascending position, the shutter 11 is moved from the retracted position to the closed position. The control device 13 may emit a signal that prohibits the movement of.

  Before or after the elevating unit 5 starts to descend, the gripping claws 3 and 3 expand outward, reach the position where the rice cooker 2 is gripped, and then shrink to the inside again to grip the rice cooker 2. Sensors (not shown) are attached to the gripping claws 3 and 3, and when detecting that the rice cooker 2 is gripped, a signal is sent to the control device 13 provided in the rice cooker transport device 1.

  Next, as shown in FIG. 6, when a signal notifying that the rice cooker 2 has been gripped is sent to the control device 13 provided in the rice cooker transport device 1, the control device 13 drives the elevator drive motor 7. And the raising / lowering part 5 is raised to the predetermined position of illustration with the holding part 4 and the rice cooker 2 currently hold | gripped. Also at this time, since the shutter 11 is in the retracted position, the raising operation is not hindered.

  Further, as shown in FIG. 7, it is detected by the above-described sensor or the vertical position detecting means provided in the elevating unit 5 that the elevating unit 5 is raised to a predetermined position together with the grasping unit 4 and the rice cooker 2 being grasped. Then, the control device 13 provided in the rice cooker transport device 1 gives the shutter 11 permission to move from the retracted position to the closed position, and drives the shutter driving motor 12 to show the shutter 11 from the retracted position. Move to the closed position. When the shutter 11 reaches a predetermined closing position, a shutter closing signal is issued, and the control device 13 provided in the rice cooker transport device 1 gives the traveling unit 6 permission to start traveling and drives the traveling motor 8 to drive the traveling motor 8. The rice cooker transport device 1 is moved to the next predetermined position. Also in this case, since the shutter 11 is in the closed position that covers the grip 4 from below, even if oil, dust, dust, water droplets, mechanical parts, etc. fall from the grip 4 or the lift 5, the shutter 11 is received by 11 and does not fall on the rice cooking unit 14 located under the traveling rice cooker transport device 1. While the traveling unit 6 is traveling, a traveling unit traveling signal is issued, and movement of the shutter 11 from the closed position to the retracted position is prohibited.

  The above is the case of taking out the rice cooking pot 2 from the rice cooking unit 14, but when the rice cooking pot 2 is set in the rice cooking unit 14, it is clear that the procedure is the reverse of the above description. Moreover, the rice cooker conveyance apparatus 1 of this invention is conveyed not only by taking out the rice cooker 2 from the rice cooking unit 14, or setting the rice cooker 2 in the rice cooking unit 14, but also by another upstream conveyance line, and waiting. Needless to say, the rice cooker in the state can be gripped, lifted and transported, and the rice cooker can be transported, lowered and opened onto another transport line on the downstream side.

  As shown in FIGS. 4 to 6, when the shutter 11 is in the retracted position, the shutter 11 is inclined, so that falling objects received by the shutter 11 may fall from the shutter 11 in some cases. There is a risk that. In such a case, for example, as shown in FIG. 8, it is preferable to provide a falling object receiver 15 at the lower end of the shutter 11 at the retracted position. In the illustrated example, the falling object receiver 15 has a shape in which the end of the shutter 11 is folded back inward, and even if the shutter 11 is inclined, it receives the falling object on the shutter 11 and falls downward. Can be prevented.

  The fallen object receiver 15 may be provided at least at the lower end portion of the shutter 11 in the retracted position, but may be provided also on the side portion of the shutter 11. When the shutter 11 moves to the retracted position and is tilted, the fallen object receiver 15 catches anything that rolls, slides, or flows on the shutter 11 so that it does not fall below the shutter 11. The shape is not limited to the shape in which the end portion of the shutter 11 is folded inward as shown in FIG. For example, as shown in FIG. 9, a shape in which a recess is once provided in the end portion of the shutter 11 and then folded inward may be used. Further, the falling object receiver 15 does not necessarily have to be formed by recessing or folding the end of the shutter 11, and other members are recessed or folded by means such as welding or adhesion. You may attach so that.

  Note that the method of enabling the shutter 11 to move between the closed position and the retracted position is not limited to the method of rotating the shutter having the shape described above around the rotation axis. For example, a flexible and foldable flexible sheet-like member may be horizontally stretched to a closed position, and drawn to one side to draw a curtain and folded to a retracted position. Further, a sheet-like member that is folded in a bellows shape may be pushed horizontally to be in the closed position as described above, folded along the bellows fold, and drawn to one side to be in the retracted position. Alternatively, the shutter may be formed in a fan shape, and the state where the fan is widened may be the closed position, and the state where the fan is folded is the retracted position. As described above, “movable between the closed position and the retracted position” in this specification includes not only the movement of the position of the shutter 11 but also the change of the shape. In short, any shape and structure of the shutter can be used as long as it can move between a closed position that covers the grip portion 4 from below and a retracted position that does not hinder the lifting and lowering operation of the lifting and lowering portion 5. However, as exemplified above, a shutter constituted by a plate-like or sheet-like member having a shape obtained by cutting a part of a cylinder along the axial direction of the cylinder is used. It is most preferable to make it possible to move between the closed position and the retracted position by rotating about a non-rotating shaft because it can be realized in a limited space and with a simple mechanism.

  FIG. 10 is a diagram illustrating another example of the rice cooker transport device 1 according to the present invention, and the same members as those described above are denoted by the same reference numerals. In the rice cooker conveying apparatus 1 shown in FIG. 10, two gripping units 4 and two lifting units 5 are provided for one traveling unit 6, and two rice cookers 2 are conveyed at a time. Can be done. In the illustrated example, the shutter driving motor 12 that moves the shutter 11 is also used as one motor to move the two shutters 11, 11. A motor 12 may be provided. Of course, even when one shutter drive motor 12 is also used as a power source for moving the two shutters 11 and 11, the movement of the two shutters 11 and 11 is made independent through appropriate clutch means. The control device 13 can hold and release the two gripping portions 4 and 4, lift and lower the two lifting portions 5 and 5, and move the two shutters 11 and 11. Can be controlled independently of each other.

  According to such a rice cooker transport apparatus 1 of the present invention, two rice cookers 2 can be transported at a time. For example, during the transportation of one rice cooker 2, it stops on an appropriate rice cooking unit 14. Then, another rice cooker 2 is taken out from the rice cooking unit 14 and transported, or is stopped on an appropriate rice cooking unit 14 while another rice cooker 2 is being transported, and another rice cooker 2 can be lowered and installed in the rice cooking unit 14, and the conveyance efficiency can be improved more than when the conveyance capacity is simply doubled.

  In addition, the number of the holding | grip part 4, the raising / lowering part 5, and the shutter 11 mounted in the one traveling part 6 is not restricted to two of illustration, Three or more may be sufficient. Further, in the illustrated example, the two gripping parts 4, 4, 2 lifting parts 5, 5, and 2 shutters 11, 11 are all arranged side by side along the traveling direction of the rice cooker transport device 1. However, in the case of a rice cooking line in which a plurality of rice cooking units 14, 14, 14... Are arranged in two rows or three or more rows, for example, two or more gripping portions 4 and lifting portions 5. The shutter 11 may be arranged side by side in a direction parallel to the traveling direction of the rice cooker transport device 1.

  As described above, according to the cooking container transport device and the heating cooking system of the present invention, it is possible to perform sanitary and safe transport of the cooking container and heat cooking, and to heat the cooking container transport device. Since it can be installed on the cooking line, there is an advantage that space can be saved. When the cooking container transport device and the heating cooking system of the present invention are applied to rice cooker transportation and rice cooking, it is possible to cook in a sanitary, safe and space-saving manner. In view of the prosperity of the industry, the impact on the related industry is significant.
