  The dish cleaning device of the present invention preferably includes a sliding contact pressure increasing means for increasing a sliding contact pressure during continuous sliding contact between the dish on the upper running surface of the belt conveyor and the cleaning brush.

  The sliding contact pressure increasing means, for example, presses the upper surface of a plate that is brought into contact with the stopper and stopped on the belt conveyor to press the plate against the belt conveyor, and the plate is perpendicular to the conveyor conveyance line. It can be a transverse feed pusher that feeds horizontally.

  Further, in another example, the sliding contact pressure increasing means has a dish upper surface abutting portion located above the dish that is brought into contact with the stopper and stopped on the belt conveyor, and the dish is moved in the conveying direction of the belt conveyor. A laterally-feeding pusher that laterally feeds in a direction perpendicular to the belt, and a belt rear surface pressing means that is located below the laterally-feeding pusher on the belt back side of the upper running surface of the belt conveyor and pushes up the conveyor belt at the position. Also good.

It is preferable to have a pair of dish side surface brushes that are provided and brush both side surfaces of the dish that is laterally fed on the rail.

  According to the above configuration, when the dishes are supplied one after another on the belt conveyor, these dishes are conveyed by the belt conveyor that is continuously driven, and the movement is stopped by the stopper located above the conveying surface of the belt conveyor. In this case, the cleaning brush is planted on the belt conveyance surface of the belt conveyor, and the belt conveyor is continuously driven in a state where the movement of the dish is stopped by the stopper, so that the cleaning brush can clean the lower surface of the dish. According to the above configuration, a space-saving and simple configuration can be provided, and the belt conveyor can have two functions of transporting the dish and cleaning the lower surface of the dish. Thus, it is possible to provide a dish cleaning apparatus capable of reliably cleaning at least the lower surface of each dish of cosmetics in a dish at high speed and in large quantities.

  According to the configuration in which negative pressure suction is performed on the cleaning brush traveling on the lower traveling surface of the belt conveyor, the cleaning brush is performed by performing negative pressure suction on the cleaning brush traveling on the lower traveling surface of the belt conveyor. It is not necessary to stop the apparatus for cleaning the belt conveyor.

  According to the structure having the sliding contact pressure increasing means, the brushing on the lower surface of the plate is strongly performed by the cleaning brush planted on the belt conveying surface of the belt conveyor, and the cleaning is performed more efficiently.

  When the lateral feed pusher presses the upper surface of the plate and presses the plate against the belt conveyor, and when the plate is laterally fed in a direction perpendicular to the conveyor conveyance line, the lateral feed pusher also serves as a sliding contact pressure increasing means.

  A cleaning brush 15 is implanted on the conveying surface of the conveyor belt 14 (see FIG. 3). The cleaning brush 15 is formed by implanting brush fibers having a length of about 3 to 8 mm, for example. The belt conveyor 10 is continuously driven when a start switch (not shown) provided in the controller 60A is turned on.

  As shown in FIG. 1, on the belt conveyor 10, a pair of guide rails 18 and 19 whose distances are adjusted according to the size of the dish P on one side reference are attached. One guide rail 18 is supported by a guide rail bracket 20 erected from the frame 11 and a support bolt 21 horizontally mounted in a cantilever manner from the bracket 20, and the other guide rail 19 is supported by the frame 11. The support bolt 23 is supported by a standing bracket 22 and a support bolt 23 horizontally mounted in a cantilevered manner from the bracket 22, and the support bolt 23 extends in a direction perpendicular to the conveyor line direction of the plate P.

  The suction removing means 27 is provided on the lower side of the belt conveyor 10 (see FIGS. 1 and 3). Since the suction removal means 27 has the same structure as that of a vacuum cleaner, a detailed configuration is not shown. The suction removing means 27 rotates the rotary blade provided inside the exhaust port to suck the adhering matter on the cleaning brush 15 from the negative pressure suction port and take it into the filter bag, and exhausts the air passing through the filter bag. By exhausting from the mouth, the deposits on the cleaning brush 15 are removed. The suction removing means 27 has a negative pressure suction port disposed in close proximity to and facing the cleaning brush 15 traveling on the lower traveling surface of the belt conveyor 10. The negative pressure suction port is formed in a wide width corresponding to the width of the conveyor belt 14 and removes deposits of the entire width of the cleaning brush 15.

  As shown in FIGS. 3 to 6, the transverse feed pusher 30 has an L-shaped pusher plate 31, and a pressing function for pressing the L-shaped pusher plate 31 against a plate P that is stopped by contact with the stopper 17 for 1 to 2 seconds. Then, the L-shaped pusher plate 31 reciprocally moves in the horizontal direction perpendicular to the conveying line of the belt conveyor 10 and has the function of laterally feeding the dish.

More specifically, as shown in FIGS. 1 and 3, the transverse feed pusher 30 is provided on the belt conveyor 10.
A transverse feed actuator 33 having a stage 32 that is provided above and moves reciprocally in a horizontal direction perpendicular to the conveying line of the belt conveyor 10, an L-shaped pusher plate mounting bracket 34 attached to the stage 32, and an L-shaped pusher plate An L-shaped pusher plate 31 having an upper surface pressing portion 31a that presses the upper surface of the plate P supported by the mounting bracket 34 so as to be movable up and down and a rear surface pressing portion 31b that hangs close to the rear surface in the lateral feed direction of the plate P and presses the rear surface. And an elevating actuator 35 that is attached to the L-shaped pusher plate mounting bracket 34 and moves the L-shaped pusher plate 31 up and down. When the upper surface pressing portion 31a of the L-shaped pusher plate 31 presses the upper surface of the plate P, the lower surface of the conveyor belt 14 corresponding to the plate P is received and the conveying surface of the conveyor belt 14 is not lowered. A receiving plate 36 is provided on the frame 11 of the belt conveyor 10.

  In this embodiment, the transverse feed actuator 33 uses a so-called single-axis table device. Specifically, for example, a box provided above the belt conveyor 10 and extending in a horizontal direction perpendicular to the conveyor line of the belt conveyor 10. A pair of timing gears 33a and 33b rotatably provided at both end positions in the frame, a timing belt 33c wound around the pair of timing gears 33a and 33b, and a side frame full length of the box frame connected to the timing belt 33c. A stage 32 engaged and guided in the opening opened to the center, and a servo motor 33d that reciprocally rotates one timing gear 33a so that the stage 32 repeats the required reciprocating operation shown in FIGS. Become. A first limit switch 37 is provided at the base end of the stage 32 so that the position can be adjusted, and a second limit switch 38 is provided at the projecting end of the stage 32 so that the position can be adjusted.

  As the lifting / lowering actuator 35, an appropriate actuator such as an air cylinder, a magnet cylinder, or a motor cylinder can be used.

The transverse feed pusher 30 extends and lowers the lifting actuator 35 to lower the L-shaped pusher plate 31, and the upper surface pressing portion of the L-shaped pusher plate 31 contacts the stopper 17 on the belt conveyor 10 and stops. When the upper surface is pressed and the plate P is pressed against the belt conveyor 10 and this pressing is performed, for example, for 1 to 2 seconds, the plate 32 is moved to the conveyor conveyance line by the L-shaped pusher plate 31 by moving the stage 32 laterally. Laterally feed in a perpendicular direction (see FIGS. 1 to 5).
In this embodiment, the elevating actuator 35 and the L-shaped pusher plate 31 are sliding contacts that increase the sliding contact pressure during continuous sliding contact between the dish P on the upper running surface of the belt conveyor 10 and the cleaning brush 15. It constitutes a pressure raising means.

  The rail 40 is provided on a rail bracket 41 provided on one side surface of the frame 11 of the belt conveyor 10 so that the interval can be adjusted in accordance with the size of the dish P. Two rails 40 extend in a direction perpendicular to the conveying level of the conveyor belt 14 in parallel and are laid in parallel, and slidably support the lower surface of the plate P that is laterally fed by the laterally-feed pusher 30. A chute (inclined plate) 42 is provided at the projecting end of the rail 40 to slide and feed the horizontally fed plate P to a lower position in the front of the lateral feed direction (see FIGS. 1 and 3).

  The pair of dish side brushes 51 and 52 are cylindrical brushes in which brush fibers having a length of, for example, 10 to 15 cm are implanted on the peripheral surface of a rotating body having a vertical axis. The rotation shafts 54 and 55 are provided so that the distance between them can be adjusted according to the size of the plate P. The brush rotation motor 53 is fixed to each rotation shaft by rotating one of the rotation shafts 54. The gear train including the gears 56 and 57 and the two intermediate gears 58 and 59 is continuously rotated in different rotational directions as indicated by arrows a and b, and is laterally fed by the lateral feed pusher 30 and slid on the rail 40. Brush both sides of the dish P to be moved (see FIGS. 2 and 5).

<About the controller 60A>
The controller 60A shown in FIG. 1 stops the servo motor 33d when the stage 32 returns to the upper side of the belt conveyor 10 and contacts the first limit switch 37 and inputs a signal output from the first limit switch 37. Output a signal. As a result, the L-shaped pusher plate 31 is positioned on the plate P stopped by the stopper (see FIG. 3).
The controller 60 </ b> A performs an extension operation on the lifting / lowering actuator 35 by inputting the detection signal of the dish sensor 26 after the servo motor 33 d stops rotating in the return movement direction of the stage 32 or by inputting the detection signal thereafter. Output a signal. Thereby, the L-shaped pusher plate 31 presses the upper surface of the plate P (see FIG. 4).
The controller 60A counts the time during which the lifting / lowering actuator 35 holds the extended state for, for example, 1 to 2 seconds, and outputs a rotation drive signal so that the stage 32 moves laterally to the servo motor 33d when the time elapses. As a result, the L-shaped pusher plate 31 feeds the plate P laterally (see FIGS. 4 and 5).
The controller 60A outputs a signal for stopping driving to the servo motor 33d when the stage 32 moves sideways and contacts the second limit switch 38 and receives a detection signal output from the second limit switch 38. Subsequently, a drive signal that reverses so that the stage 32 moves back is output (see FIG. 6).

Next, the operation of the dish cleaning apparatus 1A configured as described above will be described.
When the start switch is turned on, under the control of the controller 60A, the conveyor driving motor 16, the fan motor (not shown) of the suction removing means 27, and the brush rotating motor 53 are continuously driven, respectively. The servo motor 33d is driven to reciprocate and intermittently rotate, and the lift actuator 35 is intermittently driven. The dish cleaning apparatus 1A operates.

  The belt conveyor 10 conveys the tray P that the conveyor belt 14 continuously travels and is supplied to the upstream portion of the belt conveyor 10. The guide rails 18 and 19 align the plates P in a single-line contact state. The stopper 17 stops the top plate P that has passed through the guide rails 18 and 19.

  The cleaning brush 15 planted on the belt conveyor 10 brushes the lower surface of each plate P that is aligned and stopped in a row to remove dirt (cake) adhering to the plate P. The suction removing means 27 sucks the cleaning brush 15 on the conveying surface of the conveyor belt 14 through the negative pressure suction port, and removes the deposit (cake) adhering to the cleaning brush 15.

  When the stage 32 of the lateral feed pusher 30 finishes the lateral feed movement and returns, and stops at the lateral feed start position, the L-shaped pusher plate 31 is positioned above the plate P stopped by the stopper 17 on the conveyor belt 14. When the dish sensor 26 confirms that the dish P is under the L-shaped pusher plate 31, the elevating actuator 35 is extended to lower the L-shaped pusher plate 31. Thereby, the upper surface of the plate P is pressed by the upper surface pressing portion 31a of the L-shaped pusher plate 31, and the plate P is pressed against the belt conveyor 10 for 1 to 2 seconds. During this time, since the conveyor belt 14 runs continuously, the cleaning brush 15 strongly brushes the lower surface of the plate P and removes the cake adhering to the lower surface of the plate P.

  After the upper surface pressing portion 31a of the L-shaped pusher plate 31 presses the upper surface of the plate P for 1 to 2 seconds, the lifting / lowering actuator 35 weakens the applied pressure without rising and slightly contacts the upper surface of the plate P. Then, when the servo motor 33d rotates forward, the lateral feed pusher 30 starts to move the stage 32 supporting the L-shaped pusher plate 31 in the lateral feed direction. When the plate P is laterally fed, one subsequent plate is conveyed and stopped by the stopper 17.

  When the movement of the stage 32 in the lateral feed and lateral feed directions is started, the L-shaped pusher plate 31 abuts the rear surface pressing portion 31b on the rear surface in the lateral feed direction of the dish P, and feeds the dish P in the lateral direction. The pair of dish side brushes 51 and 52 brush the both side surfaces of the dish P and remove the cake adhering to the dish P when the dish P that is laterally fed by the L-shaped pusher plate 31 passes.

When the L-shaped pusher plate 31 is laterally fed to the tip of the rail 40, the servo motor 33d stops the forward rotation, and the lifting / lowering actuator 35 is retracted so that the L-shaped pusher plate 31 is lifted and separated from the plate P. P slides down on the chute 42.
Thereafter, when the servo motor 33d is driven by switching from forward rotation to reverse rotation, the lateral feed pusher 30 returns the L-shaped pusher plate 31 to an upper position separated from the plate P on the conveyor belt 14.

An endless timing belt 73 that circulates clockwise in FIG. 8 in a vertical plane, and a plurality of (provided at each position that divides the circumference of the timing belt 73 into two equal parts in the example of FIG. 8). 2) feed claws 74 and 75, and a lateral feed servomotor 76 for driving and rotating one timing gear 71.

  In the lateral feed pusher 70, an endless timing belt 73 abuts on the upper surface of the plate P. The timing belt 73 functions as a plate upper surface contact portion. The transverse feed pusher 70 has two feeding claws 74 and 75 alternating and pushes the rear surface in the transverse feed direction of the plate P that is stopped by abutting against the stopper 17 on the belt conveyor 10 to make a right angle to the conveying line of the belt conveyor 10. Moves horizontally in the horizontal direction.

  As shown in FIGS. 8 to 10, the belt back surface pressing means 80 is provided on the frame 11 of the belt conveyor 10 so as to be movable up and down corresponding to the lower side of the lateral feed pusher 70 and presses the belt back surface on the upper running surface of the belt conveyor 10. A belt back surface pressing plate 81, a cam receiving block 82 which is provided on the lower surface of the belt back surface pressing plate 81 and has a recess in the block, and the upper surface of the recess and the lower surface of the recess serve as a cam receiving surface; A rotating shaft 83 supported at both ends of the frame 11 so as to be adjustable in height and passed through the cam receiving block 82, and a pair of shafts fixed to the rotating shaft 83 in an eccentric state and engaged with the upper surface and the lower surface of the recessed portion of the cam receiving block 82 An eccentric disc cam 84, and a rotation actuator 85 that reciprocally rotates the rotary shaft 83 at an angle of 180 ° based on the control of the controller 60B. That.

  The belt back surface pressing unit 80 rotates the rotation actuator 85 by 180 °, thereby changing the pair of eccentric disk cams 84 halfway by changing the maximum radius downward from the center of the rotation shaft upward. Then, the cam receiving block 82 is lifted by the cam action of the eccentric disk cam 84 by 180 ° rotation, and the belt back surface pressing plate 81 corresponds to the plate P which is stopped by contacting the stopper on the upper running surface of the belt conveyor. Press the back of the belt for the full width of the belt to be pressed. In this embodiment, the belt back surface pressing means 80 uses a cam, but other means such as an air cylinder may be used.

  In this embodiment, the lateral contact pusher 70 and the belt back surface pressing means 80 are used for sliding contact to increase the sliding contact pressure during continuous sliding contact between the dish P on the upper running surface of the belt conveyor 10 and the cleaning brush 15. It constitutes a pressure raising means.

<About the controller 60B>
In the controller 60B, one feed claw of the lateral feed pusher 70 is close to the rear surface in the lateral feed direction of the plate P that is stopped by contact with the stopper 17 on the belt conveyor 10 (in FIG. 8, the feed claw 74 is close). When a detection signal for the feed claw 74 output by the proximity switch 77 provided to detect the claw 74 is input at this position, the rotation of the lateral feed servo motor 76 is stopped.
When both the detection signal of the proximity switch 77 and the detection signal of the dish sensor 26 are input, the controller 60B outputs a control signal for rotating the rotation actuator 85 by 180 °. Thereby, the belt back surface pressing plate 81 of the belt back surface pressing means 80 presses the belt back surface of the upper running surface of the belt conveyor 10.
The controller 60 </ b> B outputs a control signal that causes the rotation actuator 85 to rotate 180 ° reversely after, for example, 1 to 2 seconds after the rotation actuator 85 rotates 180 °. Thereby, the belt back surface pressing plate 81 of the belt back surface pressing means 80 releases the pressure on the belt back surface of the upper running surface of the belt conveyor 10.
The controller 60B outputs a control signal to a driver (not shown) of the lateral feed servomotor 76 so that the lateral feed pusher 70 performs lateral feed after the rotary actuator 85 rotates 180 °.

Next, the operation of the dish cleaning apparatus 1B configured as described above will be described.
When the start switch is turned on, the dish cleaning device 1B is operated based on the control of the controller 60B. The belt conveyor 10 conveys the dishes P supplied to the upstream part of the belt conveyor 10, and the guide rails 18 and 19 align the dishes P in a row. The stopper 17 stops the top plate P that has passed through the guide rails 18 and 19. The cleaning brush 15 brushes the lower surface of each plate P that is aligned and stopped in a row to remove dirt (cake) adhering to the plate P. The suction removing means 27 sucks the cleaning brush 15 on the conveying surface of the conveyor belt 14 through the negative pressure suction port, and removes the deposit (cake) adhering to the cleaning brush 15. Each operation described above is the same as that of the first embodiment.

<Operation of the transverse feed pusher 70 and the belt back surface pressing means 80>
The horizontal feed pusher 70 performs horizontal feed of the dish with one feed claw, and during this time, the other dish P is not laterally fed with respect to the next dish P that is brought into contact with and stopped by the stopper 17 on the belt conveyor 10. When the feed claw comes close to the rear surface in the lateral feed direction of the plate P that is stopped by contact with the stopper 17 on the belt conveyor 10, the lateral feed operation is stopped. The timing belt 73 of the lateral feed pusher 70 is in close contact with the upper surface of the plate P.

  Next, the belt back surface pressing means 80 presses the belt back surface corresponding to the plate P that is brought into contact with and stopped by the stopper 17 by the belt back surface pressing plate 81 by rotating the rotation actuator 85 by 180 °. For this reason, the plate P is pinched between the running belt conveyor 10 and the timing belt 73 of the lateral feed pusher 70. This clamping pressure is maintained for 1-2 seconds. Thereby, the cleaning brush 15 on the conveying surface of the conveyor belt 14 brushes the lower surface of the dish to remove cake stains on the lower surface of the dish.

Next, the rotation actuator 85 is rotated 180 ° reversely, the belt back surface pressing plate 81 is lowered to the original height position to release the pressure on the belt back surface, the lateral feed servo motor 76 is driven, and the lateral feed pusher is driven. The 70 feed claws push the rear surface of the plate P in the lateral feed direction to perform lateral feed.
The transverse feed pusher 70 and the belt back surface pressing means 80 repeat the above operations.

  The pair of dish side brushes 51 and 52, when the dish P which is laterally fed by the L-shaped pusher plate 31 passes, brushes both side surfaces of the dish P to remove the adhering to the dish P (see FIG. 9). ).

  When the feed claws 74 and 75 are laterally fed to the tip of the rail 40, they are separated from the plate P, and the plate P slides down on the chute 42 (see FIG. 10).
