Japanese Utility Model Laid-Open No. 4-10844

However, in the above conventional cleaning system, in order to start the cleaning of the object to be cleaned, it is necessary to press the transfer start button after mounting the object to be cleaned on the mounting portion of the transfer device. .. Further, the worker may wash his or her hands before pressing the transport start button in order to prevent the transport start button from becoming dirty by pressing the transport start button with the hand that preliminarily washed the object to be cleaned. Etc. had arisen.

An object of the present invention is to provide a cleaning system capable of improving workability when starting cleaning of an object to be cleaned.

A cleaning system according to the present invention includes a transfer device for transferring an object to be cleaned, a cleaning device for cleaning the object to be cleaned transferred by the transfer device, and a lift for transferring an object to be cleaned transferred from the cleaning device to a wagon. An apparatus and a control device for controlling the transfer device, wherein the transfer device transfers a cleaning device mounted on the mounting part and a cleaning part mounted on the mounting part to the cleaning machine. The control device includes a mechanism and a detection unit that detects that the cleaning target is placed on the mounting unit. Based on the detection of the cleaning target by the detection unit, the control device determines the cleaning target by the transport mechanism. Start transportation.

In the cleaning system having this configuration, when the detection unit detects that the cleaning target is placed on the mounting unit, the cleaning target is automatically conveyed. As a result, it is not necessary to press the transport start button to start the transport of the object to be cleaned. As a result, workability at the time of starting the cleaning of the object to be cleaned can be improved.

In the cleaning system according to the present invention, the detection unit includes a first detection unit that detects an object to be cleaned located at a first distance from the cleaning machine in the direction in which the object to be cleaned is transferred by the transfer mechanism, and the cleaning machine. A second detection unit that detects an object to be cleaned at a position at a second distance that is closer to the first distance than the first distance, and the control device performs cleaning in the order of the first detection unit and the second detection unit. When the object is detected, the transfer mechanism may start the transfer of the object to be cleaned. In the cleaning system having this configuration, it is possible to detect that the object to be cleaned is slid to the cleaning machine side on the mounting portion. As a result, when the object to be cleaned is placed on the placing part without the intention of starting the cleaning, or when the object to be washed before storing the dishes is placed on the placing part, the cleaning is automatically performed. It can be prevented from being started.

In the cleaning system according to the present invention, in addition to the configuration of detecting the slide of the object to be cleaned toward the cleaning machine side, even if the detection range of the first detection unit is narrower than the detection range of the second detection unit. Good. Here, in the configuration in which the conveyance mechanism starts the conveyance of the cleaning object when the cleaning object is detected in the order of the first detection section and the second detection section, the rectangular cleaning object is slanted on the mounting section. When placed in the state of being set, the first detection unit may detect the object to be cleaned before the second detection unit, and it is erroneously detected that the object to be cleaned has slid toward the cleaning machine. There are cases where In the present embodiment, since the occurrence of such erroneous detection can be reduced, it is possible to improve the detection accuracy of the sliding of the cleaning target.

In the cleaning system according to the present invention, the detection unit may be arranged so that the detection direction of the target object is inclined from the horizontal plane. Most kitchens, etc. where a cleaning system is installed are small, and other kitchen equipment with a stainless steel surface is also installed. Since the surface of such kitchen equipment generally has a high reflectance, even if the detection part for which the detection range for the object to be cleaned is set to a predetermined distance, or even the detection part having such performance, When such a kitchen device exists outside the range, the detection unit may erroneously detect the kitchen device as an object to be cleaned. In the present invention, it is possible to prevent the reflected light from returning to the detection unit by arranging the target object so that the detection direction is inclined from the horizontal plane. This makes it possible to reduce false detections.

The cleaning system according to the present invention further includes a non-contact sensor capable of detecting the object to be detected without contacting the object to be detected, and the transfer device includes an object to be cleaned by the transfer mechanism based on the detection of the object to be detected by the non-contact sensor. May be started to be transported. In the cleaning system having this configuration, the worker or the like can start the conveyance of the object to be cleaned by holding the non-contact sensor over the hand. As a result, it is possible to easily start the transportation of the object to be cleaned. Further, with this configuration, since the stain or the like caused by the operator manually pressing the transport start button does not occur, it is possible to provide excellent hygiene.

The cleaning system according to the present invention may further include a voice recognition device that recognizes a voice, and the transport device may cause the transport mechanism to start transporting the object to be cleaned based on the recognition of the specific voice by the voice recognition device. In the cleaning system having this configuration, the worker or the like can start the conveyance of the object to be cleaned simply by emitting a specific sound. As a result, it is possible to easily start the transportation of the object to be cleaned. Further, with this configuration, since the stain or the like caused by the operator manually pressing the transport start button does not occur, it is possible to provide excellent hygiene.

In the cleaning system according to the present invention, the transport mechanism has an arm member that pushes out the object to be cleaned toward the cleaning machine, and the arm member has an advancing region that overlaps with the mounting unit in plan view, and a mounting unit. It is movably provided between the retreat area and the retreat area, and may be retreated into the retreat area when the object to be cleaned is not pushed out. With this configuration, when the object to be cleaned is not pushed out, the arm member is retracted from the mounting portion, so that the object to be cleaned can be brought closer to the upstream side of the transport device. As a result, the workability of the worker can be improved.

When the arm member 11A reaches the push-out position (when the dish rack L has been handed over to the dishwasher 4), the controller 12 drives the drive unit 11E to support the support unit as shown in FIG. Move 11B to the right.

When the arm member 11A moves rightward, the arm member 11A comes into contact with the R chamfered portion at the left end portion of the shutter 16 as shown in FIGS. 11(a) and 11(b). Although the shutter 16 is swingably connected to the inner surface of the panel forming the housing 17 via a connecting member 16A, its rotation is restricted by a stopper 16B provided at the right end of the shutter 16, and the shutter 16 rotates counterclockwise. I can't move. As a result, the movement of the arm member 11A to the right is restricted when the tip of the arm member 11A has advanced to the advance area A2. Then, as shown in FIGS. 11( a) and 11 (c ), the arm member 11</b>A rotates rightward against the biasing force of the torsion spring so that its tip faces the dishwasher 4. Move towards. The arm member 11A is housed in the retreat area A1 inside the housing 17 due to the regulation of the shutter 16 as described above. The arm member 11A moves to the standby position P1 and stands by until the push-out of the tableware rack L is detected next.

Further, when the arm member 11A reaches the pushing position, the controller 12 activates the drive motor 60 of the drive mechanism 7 after a predetermined time. As a result, the door 23 of the dishwasher 4 is closed and the door 23 is located at the closed position. The dishwasher 4 starts the washing operation when the door 23 is at the closed position. The dishwasher 4 outputs an end signal to the controller 12 when the washing operation is finished. When the controller 12 receives the end signal, the controller 12 operates the drive motor 60 of the drive mechanism 7, whereby the door 23 of the dishwasher 4 is opened and the door 23 is located at the open position.

The conveyance of the tableware rack L has started. In the cleaning system 1 having this configuration, it is possible to detect that the tableware rack L is slid to the tableware washing machine 4 side on the mounting surface 10a. As a result, when the tableware rack L is placed on the placing surface 10a without the intention of starting washing, or when the tableware rack L before storing the tableware D is placed on the placing surface 10a, It is possible to prevent the cleaning from being started.

In the cleaning system 1 according to the present embodiment, in addition to the configuration of detecting the slide of the tableware rack L toward the tableware washing machine 4 described above, the detection range of the first sensor 14A is greater than the detection range of the second sensor 14B. It is narrowing. Here, when the tableware rack L is detected in the order of the first sensor 14A and the second sensor 14B, the transport of the tableware rack L by the arm member 11A is started, for example, a rectangular tableware rack L (FIG. 9). Even when the tableware rack L indicated by the broken line in (a) is placed on the placing surface 10a from the front in a slanted state, the first sensor 14A moves the tableware rack L before the second sensor 14B. Detect. In this case, the controller 12 erroneously detects that the tableware rack L has been slid in the direction of the dishwasher 4.

In the present embodiment, since the detection range of the first sensor 14A is narrower than that of the second sensor 14B, even when the tableware rack L is diagonally arranged, the first sensor 14A can be placed before the second sensor 14B. Can be reduced. This can reduce the occurrence of erroneous detection as described above, so that the detection accuracy of the tableware rack L being slid can be improved.

By disposing the first sensor 14A and the second sensor 14B of the cleaning system 1 according to the present embodiment so that the detection direction of the tableware rack L is inclined from the horizontal plane, stainless steel having a relatively high reflectance. This prevents erroneous detection due to detection of infrared rays or the like reflected by other kitchen equipment formed by the above. This makes it possible to reduce false detections.

In the arm member 11A of the cleaning system 1 according to the present embodiment, when the tableware rack L is not pushed out, the arm member 11A is retracted from the placing surface 10a, so the upstream side of the carry table 3, that is, the dipping tank 2 It is possible to move the tableware rack L to. As a result, the operator can easily store the tableware D in the tableware rack L after preliminarily cleaning the tableware D in the dipping tank 2, so that the workability of the operator can be improved.
