Description

  The present invention relates to a dishwashing apparatus.

  2. Description of the Related Art In recent years, restaurants have used tableware washing devices that automatically wash tableware. In restaurants that transport dishes loaded with food and drinks like a conveyor belt sushi restaurant, a large number of dishes with the same shape are used, so there is a continuous cleaning device that efficiently cleans these dishes. (See, for example, Patent Document 1).

JP 2004-8319 A

  In the dish washing apparatus that automatically cleans the stacked dish dishes, an operation is carried out in which the dish dishes stacked in the dish insertion slot are sequentially dropped into the apparatus. In the tableware washing apparatus, the tableware that has been pulled in from the plate insertion port slides side by side, and the front and back surfaces of the tableware are washed. The pressing force of the brush and the washing water is applied to the dishes being washed. Therefore, in addition to the support member that supports the tableware from below, the tableware washing apparatus in which the tableware slides side by side in order to maintain the posture of the tableware being washed, A support member for supporting the dish from above is provided. Therefore, when the tableware is inserted into the plate insertion slot in an inappropriate posture, the tableware may be caught between the support members and may not move.

  Therefore, the present application discloses a tableware washing apparatus in which the tableware is not sandwiched between the support members even when the tableware is inserted into the plate insertion port in an inappropriate posture.

  In order to solve the above-mentioned problems, the present invention has arranged the lower end of the back plate stopper in the vicinity of the end of the support rail that supports the tableware being cleaned from above.

  More specifically, the present invention relates to a dish washing apparatus, comprising a dish insertion port formed on the upper surface of the housing, and a laterally extending from a lower portion of the dish insertion port in the housing, A first support rail for supporting a horizontal portion of the thread trimming portion of the tableware dropped from the insertion port from below, and a sliding means for sliding the tableware supported by the first support rail in the horizontal direction; A second support rail that is provided on the upper side of the first support rail on the lateral side of the lower portion and from which the slide means supports the tableware that is being slid from above, and the tableware that is stacked on the tray slot from below. A turn-off means for dropping the first support rail in the housing in order, a back plate stopper having a lower end disposed near the end of the second support rail on the upper side of the first support rail; Is provided.

  In addition, the thread trimming part as used in the present application is simply a bottom part of a tableware, and is not limited to, for example, ceramics cut off from a work table using a thread before firing. If it is said tableware washing | cleaning apparatus, even if a tableware dish is set in the state which turned over in the dish insertion slot, a tableware plate will contact a backplate stopper. Therefore, it cannot enter between the 1st support rail and the 2nd support rail in the state where the tableware is turned over. Therefore, the possibility that the tableware is sandwiched between the first support rail and the second support rail is suppressed.

  In addition, the lower end of the back plate stopper is in a position higher than the surface of the tableware in a state where the surface is upward and supported by the first support rail, and in a state where the surface is downward and supported by the first support rail. You may arrange | position in the position lower than the bottom part of a tableware. If the back plate stopper is arranged in this way, the bottom of the plate is positioned higher than the bottom of the back plate stopper when the plate is accidentally set upside down at the tray slot. If an attempt is made to enter between the first support rail and the second support rail while the plate is turned upside down, the thread trimming portion comes into contact with the back plate stopper to prevent entry. Therefore, the possibility that the tableware is sandwiched between the first support rail and the second support rail is suppressed.

  Further, the first support rail may have two rails wider than the thread trimming portion of the tableware. If the 1st support rail is formed in this way, when the tableware is set in the correct position at the tray slot, the surface of the tableware will be lower than the lower end of the back plate stopper, and it will be accidentally turned over. When set in, the bottom of the tableware is positioned higher than the lower end of the back plate stopper. Therefore, if the tableware is turned upside down and tries to enter between the first support rail and the second support rail, the thread trimming portion contacts the back plate stopper and the entry is blocked, and the tableware becomes the first support rail. And the possibility of being caught between the second support rails are suppressed.

  Further, the back plate stopper may be a plate-like member having a vertical plate surface. If the back plate stopper is formed in this way, the plate surface perpendicular to the sliding direction will come into contact with the tableware when the tableware that slides in the horizontal direction contacts the back plate stopper. The slide of the tableware which tries to enter between the 1st support rail and the 2nd support rail stops reliably.

  The slide means may stop the slide when detecting that the tableware is in contact with the back plate stopper. If the slide is stopped when the tableware comes into contact with the back plate stopper, the tableware will not continue to receive a reaction force from the back plate stopper.

  With the dish washing apparatus according to the present invention, the dish is not sandwiched between the support members even if the dish is thrown into the dish slot in an inappropriate posture.

Hereinafter, embodiments of the present invention will be described. Embodiment shown below is one aspect | mode of this invention, and does not limit the technical scope of this invention. Each embodiment and modification shown below are suitable, for example, for restaurants that provide various foods such as sushi, beverages, soba and udon noodles, and fried and tempura.

  Drawing 1 is an example of the perspective view showing the appearance of the dishwashing device concerning an embodiment. As shown in FIG. 1, the dish washing apparatus 1 includes a dish insertion port 3 and a dish discharge port 4 on the upper surface of a substantially rectangular housing 2. Unwashed tableware D used for eating and drinking is stacked in the tray insertion port 3. In the dish discharge port 4, the washed dish D washed by the dish washing apparatus 1 is stacked. Around the tray insertion port 3 and the tray discharge port 4, a plurality of guide bars 5 are provided so as to surround the tray insertion port 3 and the dish discharge port 4 so as to prevent the stacked dish plates D from falling over. As shown by the arrows in FIG. 1, the dish washing apparatus 1 takes in the dish D stacked in the dish insertion port 3 one by one into the machine and cleans it, and stacks it on the dish discharge port 4.

  FIG. 2 is an example of a perspective view showing a state in which the tableware D is cleaned inside the tableware cleaning apparatus 1. The dish D entering the housing 2 from the tray insertion port 3 is slid horizontally one by one by a pair of conveying screws S1 and S2 arranged parallel to each other from the tray insertion port 3 to the dish discharge port 4. And reaches the dish outlet 4. In the pair of conveying screws S1, S2, spiral grooves M1, M2 are formed in different directions. The dish D is raised and lowered by a device (not shown) provided between the tray insertion port 3 and the tray discharge port 4 and the conveying screws S1 and S2. The edge of the tableware D fits into the grooves M1 and M2 of the conveying screws S1 and S2. The dish D is supported by a dish receiving member (not shown) provided inside the pair of conveying screws S1, S2. Therefore, when the pair of conveying screws S1 and S2 rotate in the opposite direction with the edges fitted in the grooves M1 and M2, the tableware D slides sideways while sliding the plate receiving member.

  FIG. 3 is an example of a diagram showing the cleaning path 10 on which the tableware D slides. The dish washing apparatus 1 is provided with a first-stage washing nozzle 6, a rotating brush 7, a second-stage washing nozzle 8, and a drying nozzle 9 in order along a washing path 10 on which the dish D slides. ing. The first-stage cleaning nozzle 6 sprays water mixed with a cleaning chemical solution onto the dish D. The rotating brush 7 brushes the front and back surfaces of the tableware D and removes solid matter adhering to the tableware D, and is rotated by the power of a motor (not shown). The second stage washing nozzle 8 sprays water for rinsing the dish D onto the dish D. The drying nozzle 9 blows a wind for blowing off the water adhering to the tableware D on the tableware D.

  Therefore, the dish D placed in the dish insertion port 3 is washed with water blown from the first-stage washing nozzle 6 while being slid to the dish discharge port 4 by the rotation of the pair of conveying screws S1 and S2. Then, it is brushed by the rotating brush 7, rinsed with the water blown from the second stage washing nozzle 8, dried with the wind blown from the drying nozzle 9, and becomes clean. The cleaned dish D that has become clean is stacked on the dish discharge port 4 from below.

FIG. 4 is a system configuration diagram of the tableware washing apparatus 1. The dish washing apparatus 1 includes a screw drive motor 13 that drives the conveying screws S1 and S2. The dishwasher 1 also includes a hot water storage tank 23 for storing water sent to the first stage cleaning nozzle 6 and the second stage cleaning nozzle 8, and a cleaning water pump for sending the cleaning water from the hot water storage tank to each cleaning nozzle. 16. A solenoid valve 17 is provided to keep the water level of the hot water tank 23 within a certain range. Further, the dish washing apparatus 1 includes a detergent tank 15 and a detergent pump 14 for adding detergent to water flowing from the electromagnetic valve 17 to the first-stage washing nozzle 6. In addition, the dish washing apparatus 1 includes a blower 18 that sends air to the drying nozzle 9. The screw drive motor 13, the detergent pump 14, the washing water pump 16, the electromagnetic valve 17, and the blower 18 are controlled by a control device 20 connected to the dish sensor 19. The dish sensor 19 is an optical sensor that detects the presence or absence of the dish D loaded in the dish insertion port 3. While the dish sensor 19 detects the dish D, the control device 20 operates the screw drive motor 13, the detergent pump 14, the washing water pump 16 and the blower 18. While the dish sensor 19 is not detecting the dish D, the control device 20 stops the screw drive motor 13, the detergent pump 14, the washing water pump 16, and the blower 18.

  FIG. 5 is an example of a diagram showing a portion directly below the tray insertion port 3 from above. FIG. 6 is an example of a diagram showing a portion directly below the tray insertion port 3 from the front side. FIG. 7 is an example of a diagram showing a portion directly below the tray insertion port 3 from the left side. The cleaning path 10 is a path in which the dish D is cleaned while sliding in the horizontal direction, and the first support rail 11 extending in the horizontal direction from the lower portion of the dish insertion port 3 in the housing 2; It is provided on the upper side of the first support rail 11 on the lateral direction side with respect to the dish insertion port 3, and is formed by a second support rail 21 that supports the dish D being washed from above. The tray insertion port 3 is provided with a roll-off device 12 for dropping the tableware D stacked on the tray insertion port 3 into the housing 2 in order from the bottom.

  The carry-down device 12 includes two roll-down members R1 and R2 each provided with a groove MK having a size to fit the edge of the tableware D. Since the carry-down members R1 and R2 are arranged in parallel with an interval slightly narrower than the width of the tableware D, the tableware D stacked on the plate insertion port 3 can be supported from below. The carry-down members R1, R2 are members that are rotationally driven in opposite directions. When the groove MK of the carry-down member R1 faces the roll-off member R2, the groove MK of the roll-off member R2 is also on the roll-off member R1 side. The rotation angle is adjusted so that it faces. Therefore, when the dropping members R1 and R2 are rotationally driven so that the grooves MK move downward in a state where the grooves MK provided in the dropping members R1 and R2 face each other, the dropping is performed. Of the tableware D stacked on the plate insertion slot 3 while being supported by the members R1 and R2, the lowermost tableware D is fitted into the two grooves MK provided in the roll-off members R1 and R2, respectively, and the plate is inserted. It is dropped into the housing 2 from the mouth 3.

  Incidentally, a back plate stopper 22 is provided at the entrance of the cleaning path 10. The lower end of the back plate stopper 22 is disposed on the upper side of the first support rail 11 and in the vicinity of the end portion of the second support rail 21 on the lower portion side of the tray insertion port 3. The back plate stopper 22 is a plate-like member, and the plate surface is fixed vertically. Therefore, the back plate stopper 22 plays the following role.

  Hereinafter, the movement of the tableware D when the tableware D is rolled down in a correct posture will be described. FIG. 8 is a first diagram showing the operation of the carry-off device 12 dropping the tableware D.

  Since the roll-off members R1 and R2 of the roll-off device 12 are arranged in parallel with an interval slightly narrower than the horizontal width of the tableware D, they are stacked when the tableware D is stacked on the plate insertion slot 3. The dish D is supported from below (see FIG. 8A). When the carry-down members R1 and R2 rotate in this state, the lowermost tableware D of the tableware D stacked on the plate loading port 3 while being supported by the roll-off members R1 and R2 is moved to the carry-down members R1 and R1. It starts to fit into the two grooves MK provided in R2 (see FIG. 8B). Then, when the carry-down members R1 and R2 continue to rotate as they are, the lowermost tableware D is separated from the upper tableware D and eventually the grooves MK provided in the carry-down members R1 and R2. Becomes downward, the tableware D fitted in the two grooves MK falls down (see FIG. 8C). The tableware D that has been pulled down from the tray loading port 3 by the roll-off device 12 is placed on the first support rail 11 that forms the cleaning path 10.

FIG. 9 is a first view showing the state in which the tableware D slides from an oblique direction. When the roll-off members R1 and R2 rotate, the lowermost tableware D fits into the two grooves MK and is separated from the upper tableware D (see FIG. 9A). And the tableware D which was drawn down from the tray insertion port 3 by the rotation of the dropping members R1 and R2 and placed on the first support rail 11 is removed from the tray insertion port 3 by the rotation operation of the pair of conveying screws S1 and S2. Slide toward the dish outlet 4. As shown in FIG. 8C, the lower end of the back plate stopper 22 is higher than the surface of the tableware D in a state in which the back plate stopper 22 is supported by the first support rail 11 in a correct posture (that is, a posture in which the surface is upward). Placed in position. Therefore, the dish D that slides from the tray insertion port 3 toward the tray discharge port 4 by the rotational operation of the screws S1 and S2 can pass under the back plate stopper 22 without contacting the back plate stopper 22. (See FIG. 9B).

  Hereinafter, the movement of the tableware D when the tableware D is rolled down in an upside down posture will be described. FIG. 10 is a second diagram illustrating the operation of the carry-off device 12 moving the tableware D down.

  Since the carry-down members R1 and R2 of the roll-off device 12 are arranged in parallel with a space slightly narrower than the horizontal width of the tableware D, the tableware D is turned upside down at the plate insertion port 3 (that is, the yarn Even when set with the cut portion DS facing upward, the tableware D is supported from below (see FIG. 10A). Then, when the carry-down members R1 and R2 rotate in this state, the inverted dish D starts to fit into the two grooves MK provided on the roll-off members R1 and R2 (see FIG. 10B). . When the carry-down members R1 and R2 continue to rotate as they are, the tableware D falls down while being turned over (see FIG. 10C). The tableware D that has been pulled down from the tray loading port 3 by the roll-off device 12 is placed in an inverted state on the first support rail 11 that forms the cleaning path 10.

  FIG. 11 is a second view showing the state in which the tableware D slides from an oblique direction. When the carry-down members R1 and R2 rotate, the inverted dish D is fitted into the two grooves MK and separated from the upper dish D (see FIG. 11A). And the tableware D which was drawn down from the tray insertion port 3 by the rotation of the dropping members R1 and R2 and placed on the first support rail 11 is removed from the tray insertion port 3 by the rotation operation of the pair of conveying screws S1 and S2. Slide toward the dish outlet 4. However, as shown in FIG. 10 (C), the lower end of the back plate stopper 22 is the bottom of the tableware D in a state where it is supported by the first support rail 11 in an upside down posture (that is, a posture in which the surface is directed downward). It is arranged at a position lower than the bottom (the part that comes into contact with the table when placed on the table in the correct posture). Therefore, the thread trimming portion DS of the dish D that slides from the tray insertion port 3 toward the tray discharge port 4 by the rotation operation of the screws S1 and S2 contacts the back plate stopper 22 before the second support rail 21 enters. . When the thread trimming portion DS of the tableware D comes into contact with the back plate stopper 22, the torque limiter of the screw drive motor 13 of the conveying screws S1 and S2 for sliding the tableware D is operated. When the torque limiter of the screw drive motor 13 is activated, the control device 20 stops the screw drive motor 13, the detergent pump 14, the washing water pump 16 and the blower 18 and closes the electromagnetic valve 17.

  With the dish washing apparatus 1 according to the present embodiment, even if the dish D is set in the dish insertion port 3 in an inverted state, the thread trimming portion DS of the dish D contacts the back dish stopper 22. Since the screw drive motor 13 is stopped, the cleaning path 10 is not slid while the dish D is turned over. Therefore, when the tableware D enters the cleaning path 10 while being turned upside down, the tableware D is not moved between the first support rail 11 and the second support rail 21 and cannot be taken out. .

  In addition, the back plate stopper 22 is not limited to the form mentioned above. The back plate stopper 22 may be a non-plate-like member, for example. Moreover, the tableware washing | cleaning apparatus 1 is not limited to what is provided with the back plate stopper 22 when shipping from a factory as a product. For example, the dish washing apparatus 1 may be shipped to a restaurant or the like in a state where the back plate stopper 22 is omitted, and then the back plate stopper 22 is attached.
