In FIG. 2, the left-right direction of the paper surface is the front-rear direction of the sheet pallet cleaning device, and the vertical direction of the paper surface is the vertical direction of the sheet pallet cleaning device. Moreover, the left-right direction when the sheet pallet washing apparatus is viewed from the front is defined as the left-right direction of the apparatus.

  As shown in FIGS. 1 and 2, the sheet pallet cleaning apparatus 1 according to the present invention is configured by providing a cleaning process unit 30 for cleaning the sheet pallet S at an upper portion in a box-shaped housing 10 having an upper opening. Is done.

  The housing 10 is made of a steel material or the like that has been subjected to rust prevention treatment such as galvanization, and is supported by four columns 11 provided with casters 17. An insertion port 12 and a discharge port 13 for the sheet pallet S are formed at the front and rear of the casing 10, respectively, and the sheet pallet S before cleaning is fed into the insertion port 12 into the insertion port 12. And a receiving stand 15 for receiving the sheet pallet S discharged from the discharge port 13 is provided at the discharge port 13. In the figure, reference numeral 16 denotes a free roller. When the free roller 16 freely rotates, the work after the sheet pallet S is inserted or discharged can be easily performed.

  A cleaning process unit 30 for cleaning the sheet pallet S is disposed on the upper portion of the housing 10. As shown in FIG. 2, the cleaning process unit 30 includes conveyance rollers 31, 32, and 33 that feed the sheet pallet S into the cleaning device 1 and send it out of the cleaning device 1, and dirt attached to the sheet pallet S. Cleaning brushes 34 and 35, cleaning water spray nozzles 36 and 37 for spraying cleaning water onto the sheet pallet S, and a rinsing cleaning water spray nozzle for spraying rinsing water onto the cleaned sheet pallet. 38, 39.

  The conveyance rollers 31, 32, and 33 are members that convey the sheet pallet S from the insertion port 12 to the discharge port 13, and are disposed at a certain interval in the front-rear direction of the housing 10. Each of the conveying rollers 31, 32, and 33 is configured by arranging a pair of upper and lower rubber rotating rollers each having a metal shaft as a core. The sheet pallet S is conveyed from the insertion port 12 to the discharge port 13 by rotating so as to be wound. These transport rollers 31, 32, 33 are transport rollers disposed at the lower part of the casing 10 by chains 41, 42, 43 and gears 44, 45, 46, 47 as shown in FIGS. The motor 40 is connected to the motor 40 and rotates.

  The cleaning brushes 34 and 35 are formed by implanting a large number of straight and wavy nylon hairs on the peripheral wall of a cylindrical member having substantially the same diameter as the rotating rollers constituting the transport rollers 31, 32 and 33. The diameters of the rotating brushes of the cleaning brushes 34 and 35 including the planted hair are at least twice as large as the diameters of the rotating rollers constituting the conveying rollers 31, 32 and 33. The cleaning brushes 34 and 35 are each composed of two upper and lower rotating brushes. The cleaning brush 34 is disposed between the transport rollers 31 and 32, and the cleaning brush 35 is disposed between the transport rollers 32 and 33. . The cleaning brushes 34 and 35 remove the dirt attached to the sheet pallet S by rotating and contacting the sheet pallet S conveyed by the conveyance roller 31 or the conveyance roller 32. Further, since the rotation direction of the cleaning brushes 34 and 35 is the same as the rotation direction of the conveying rollers 31, 32 and 33, the cleaning can be performed without hindering the conveyance of the sheet pallet S. As shown in FIG. 3, the cleaning brushes 34 and 35 rotate in conjunction with a cleaning brush motor 50 disposed in the lower portion of the housing 10 by chains 51, 52, 53 and 54 and a driven sprocket 55. Perform the action.

  As shown in FIG. 4, the insertion port 12 of the housing 10, the discharge port 13, the midpoints of the up and down rotation rollers of the transport rollers 31, 32, and 33 of the cleaning process unit 30, The midpoints of the up and down rotating brushes are arranged on substantially the same straight line, and this line becomes the conveyance path 80 of the sheet pallet S.

  Here, in the sheet pallet cleaning apparatus 1 according to the present embodiment, as illustrated in FIG. 4, the rotation operation of the conveyance roller motor 40 and the cleaning brush motor 50 is performed by the operation unit 18 provided at the upper end of the housing 10. It is configured to be able to perform start / stop operations and rotation direction reversal operations. That is, the operation unit 18 includes a rotation direction change switch (not shown) as a rotation direction change unit, and the rotation direction of the transport roller motor 40 and the cleaning brush motor 50 is determined by pressing the rotation direction change switch. Invert. As the rotation directions of the motors 40, 50 are reversed, the rotation directions of the conveyance rollers 31, 32, 33 and the cleaning brushes 34, 35 are also reversed, so that the sheet pallet S is conveyed to the insertion port 12 side. Become. Therefore, when cleaning the severely contaminated sheet pallet S, the sheet pallet S is conveyed to the discharge port 13 side to some extent, and then conveyed to the insertion port 12 side by using the rotation direction changing means. Can be cleaned carefully.

  Further, the operation unit 18 is provided with a speed adjustment switch (not shown) as a rotation speed changing means, and the rotation speed of the conveyance roller motor 40 can be adjusted by pressing the speed adjustment switch. Therefore, when cleaning the sheet pallet S that is heavily soiled, the rotation speed of the conveyance rollers 31, 32, and 33 is decreased by decreasing the rotation speed of the conveyance roller motor 40. In the case of cleaning the sheet pallet S that can be cleaned and is not very dirty, the rotation speed of the transport rollers 31, 32, and 33 is increased by increasing the rotation speed of the transport roller motor 40. Therefore, the sheet pallet S can be cleaned in a short time.

  Here, the change of the rotation direction and the adjustment of the rotation speed are controlled by a control unit 90 provided in a control box 19 provided in the lower left portion of the housing 10 as shown in FIG. The control device of the sheet pallet washing apparatus 1 in the present embodiment is configured as shown in FIG. 5, and when the control unit 90 detects that the rotation direction change switch provided in the operation unit 18 is pressed, The drive circuit 91 for the transport roller and the drive circuit 92 for the cleaning brush are requested to rotate the motor in reverse, and the drive circuits 91 and 92 that have received the request respond to the request and the motor 40 for the transport roller and the cleaning brush The motor 50 is rotated in the reverse direction.

  Similarly, when the control unit 90 detects that the rotation speed change switch provided in the operation unit 18 is pressed, the control unit 90 requests the conveyance roller drive circuit 91 to change the rotation speed of the motor, and the request. In response to the request, the conveyance roller drive circuit 91 changes the rotation speed of the conveyance roller motor 40.

  The cleaning water spray nozzles 36 and 37 are members for spraying cleaning water onto the upper surface of the sheet pallet S, and are disposed in the vicinity of the upper end of the housing 10. The cleaning water spray nozzle 36 is disposed between the transport roller 31 and the cleaning brush 34, and the cleaning water spray nozzle 37 is disposed between the transport roller 32 and the cleaning brush 35, and the upper rotating brush is cleaned. In order to supply water, these injection ports are directed near the lower ends of the upper rotating brushes of the cleaning brushes 34 and 35.

  In addition, the sheet pallet washing apparatus 1 according to the present embodiment can sufficiently remove the dirt adhered to the sheet pallet S by the washing water and the washing brushes 34 and 35, and even if the dirt is severe, it will be described later. As described above, since careful cleaning can be performed by changing the rotation direction and rotation speed of the transport rollers 31, 32, and 33 and the cleaning brushes 34 and 35, a detergent or the like that may adversely affect the environment is used. There is no need.

  Further, rinse water spray nozzles 38 and 39 for rinsing are disposed between the transport roller 33 and the discharge port 13. As will be described later, since the wash water stored in the water storage tank 71 is wash water that has been reused for the plurality of sheet pallets S, it is not preferable to finish washing with such wash water attached. . Therefore, the cleaning water spray nozzles 38 and 39 for rinsing are provided above and below the sheet pallet S with the conveying path of the sheet pallet S interposed therebetween, so that the used cleaning water is rinsed off and the cleaning is finished in a cleaner state. . The cleaning water spray nozzles 36 and 37 and the rinsing cleaning water spray nozzles 38 and 39 are connected to a cleaning water supply pipe 60 disposed on the left side surface of the sheet pallet cleaning device 1 as shown in FIG. The cleaning water supplied from the cleaning water supply pipe 60 is jetted.

  Further, the housing 10 has a guide 20 serving as a guide plate when the sheet pallet S conveyed from the conveying roller 33 is conveyed from the discharge port 13 to the receiving base 15. As shown in FIG. 5, the guide 20 is a substantially U-shaped plate-like member whose front end portion and rear end portion are bent downward, and the front end portion is oblique to the conveyance path 80 of the sheet pallet S. It arrange | positions at the lower end of the discharge port 13 so that it may cross. With this configuration, when the sheet pallet S is sent out from the conveyance roller 33, the sheet pallet S comes into contact with the front end portion of the guide 20 and rides on the guide 20, and is discharged out of the housing 10 while being inclined along the guide 20. Will be. Therefore, since the washing water remaining on the sheet pallet S is poured into the water storage tank 71 along the inclination, there is no fear that the washing water leaks out of the sheet pallet washing apparatus 1, which can further contribute to water saving.

  Further, the cleaning water remaining on the upper surface of the sheet pallet S is removed between the rotary roller on the upper side of the conveying roller 33 and the discharge port 13, particularly between the rinsing cleaning nozzle 38 and the discharge port 13. A draining rubber 21 is disposed in contact with the guide 20. The water draining rubber 21 has an upper portion integrally connected to a metal support 23, and both ends of the support 23 are supported by support portions 22, 22 disposed on the inner wall of the housing 10. 10 is fixed inside. By providing the draining rubber 21, the washed sheet pallet S transported on the guide 20 is transported while the upper surface is in contact with the draining rubber 21, so that the cleaning water adhering to the portion can be removed. It becomes possible. Moreover, since the wash water removed by the water rubber 21 is stored again in the water storage tank 71, the amount of water to be used can be saved.

  The cleaning water sprayed by the cleaning water spray nozzles 36 and 37 and the rinsing cleaning water spray nozzles 38 and 39 is provided inside the housing 10 and below the cleaning process unit 30 configured as described above. 10 A water storage tank 71 is provided so as not to splash outside. As shown in FIG. 2, the water storage tank 71 includes a water level adjusting pipe 72 that discharges only cleaning water that exceeds a predetermined water level to the outside of the casing 10, and all the cleaning water in the water storage tank 71 outside the casing 10. And a drain pipe 73 to be discharged.

  When a predetermined amount of cleaning water is stored in the water storage tank 71, the lower end of the lower rotating brush of the cleaning brushes 34 and 35 is in a state of being immersed in the cleaning water to some extent. When the cleaning brushes 34 and 35 are rotated in this state, the lower rotating brush scoops up the cleaning water by the rotating operation and cleans the lower surface of the sheet pallet S together with the cleaning water thus sprinkled. Do.

  At this time, most of the cleaning water sprinkled by the cleaning brushes 34 and 35 falls on the sheet pallet S and then drops and is stored in the water storage tank 71 again. Therefore, since the cleaning water once used for cleaning can be reused, the amount of cleaning water used can be greatly reduced.

  On the other hand, the cleaning water sprayed from the cleaning water spray nozzles 36 and 37 and the rinsing cleaning water spray nozzles 38 and 39 also accumulates in the water storage tank 71. As a result, the level of the cleaning water in the water storage tank 71 increases. . When the water level of the cleaning water increases, the cleaning brushes 34 and 35 are resisted more than necessary, which impedes the rotation operation, and the transport rollers 31, 32 and 33 are immersed in the cleaning water, so that the sheet pallet S can be smoothly transported. Is not preferable because it may be hindered or adversely affect various other driving members. Therefore, in the present embodiment, such a problem is solved by providing the water level adjusting pipe 72 on the side surface of the water storage tank 71.

  The water level adjusting pipe 72 is a pipe-like member curved downward, and is provided at a location corresponding to the side surface of the water storage tank 71 and the front surface of the housing 10. By providing such a water level adjusting pipe 72, cleaning water exceeding a predetermined water level is discharged out of the sheet pallet cleaning apparatus 1 through the water level adjusting pipe 72. Therefore, since the sheet pallet washing apparatus 1 can always maintain the predetermined water level, there is no inconvenience due to an increase in the water level as described above.

  Here, the predetermined water level is an optimum water level for the operation of the sheet pallet washing apparatus 1, and is specifically higher than the lower end of the lower rotating brush, and the rotation of these lower rotating brushes. It refers to a position lower than the axes 34 'and 35'. In this way, by setting the position higher than the lower end of the lower rotating brush, it is possible to prevent the cleaning water from being supplied to the sheet pallet S because the lower rotating brush does not contact the cleaning water. In addition, by setting the lower rotary brush at a position lower than the rotation shafts 34 'and 35', the lower rotary brush is excessively in contact with the cleaning water, so that the lower rotary brush is more than necessary from the cleaning water. It can prevent receiving resistance. Furthermore, as described above, the intermediate point of the up-and-down rotation rollers of the transport rollers 31, 32, and 33 and the intermediate point of the up-and-down rotation brushes of the cleaning brushes 34 and 35 are in a straight line. Since it has a diameter at least twice the diameter of the transport rollers 31, 32, 33, even if the predetermined water level is in the vicinity of the rotary shafts 34 ', 35' of the lower rotary brush, the transport rollers 31, 32 , 33 does not come into contact with cleaning water.

  Moreover, as shown in FIG. 2, it is formed in the substantially V shape by the side view at the bottom part of the said water tank 71. As shown in FIG. Further, a drainage pipe 73 for discharging all the cleaning water in the water storage tank 71 to the outside of the housing 10 when the cleaning of the sheet pallet S is completed is provided in the valley portion of the substantially V-shaped bottom. It has been. With this configuration, when all the cleaning water in the water storage tank 71 is discharged to the outside of the housing 10, the cleaning water, the mud removed from the sheet pallet S, and the like, that is, the drain pipe 73 according to gravity. Since it gathers around, the washing water, mud, etc. which remain | survive in the bottom part of the water storage tank 71 can be reduced, and discharge operation | work of this washing water can be performed rapidly.

  The sheet pallet washing apparatus 1 in the present embodiment is configured as described above, and the operation thereof will be described in detail below with reference to the drawings.

  When cleaning the sheet pallet S using the sheet pallet cleaning apparatus 1 according to the present embodiment, first, the cleaning water supply pipe 60 is connected to a water pipe or the like, and the cleaning water jet nozzles 36 and 37 and the rinsing cleaning water are used. Washing water is supplied to the spray nozzle 38 and the washing water is stored in the water storage tank 71. At this time, in order to prevent the cleaning water from being jetted upward, the valve 61 provided in the cleaning water supply pipe 60 is closed so that the cleaning water is not supplied to the rinsing cleaning water spray nozzle 39. Next, the sheet pallet cleaning device 1 is turned on, and the rotation start switches of the conveying rollers 31, 32, 33 and the cleaning brushes 34, 35 are pressed to rotate them. Then, after opening the valve 61 and supplying cleaning water to the rinsing cleaning water jet nozzle 39, as shown in FIG. 1, the sheet pallet S is fed and placed on the mount 14 and slid on the free roller 16 to be inserted into the insertion port. Move to 12.

  As shown in FIG. 2, the sheet pallet S that has entered the apparatus 1 from the insertion port 12 is caught in the rotation of the up and down rotation rollers of the conveying roller 31 and conveyed to the back of the apparatus 1. Next, the sheet pallet S conveyed by the conveying roller 31 is cleaned by the cleaning brush 34. At this time, the upper rotary brush removes dirt in cooperation with the cleaning water sprayed from the cleaning water spray nozzle 36. Further, the lower rotating brush pumps up the cleaning water stored in the water storage tank 71 by its own rotating operation, and removes dirt in cooperation with the cleaned cleaning water. Next, the sheet pallet S is conveyed further back by the conveying roller 32 and is cleaned by the cleaning brush 35 and the cleaning water spray nozzle 37. If the sheet pallet S is very dirty, the rotation direction and rotation speed of the conveying rollers 31, 32 and 33 and the cleaning brushes 34 and 35 are changed by using a rotation direction changing means and a speed adjustment unit. Careful cleaning of the pallet S can also be performed. Next, the sheet pallet S is subjected to final rinse by the rinse water spray nozzles 38 and 39 disposed in the vicinity of the discharge port 13, so that the water stored in the plurality of sheet pallets S is reused. The washing water in the tank 71 is removed.

  Finally, after the cleaning water remaining by the guide 20 and the draining rubber 21 is removed, the sheet pallet S is discharged from the discharge port 13 to the outside of the apparatus 1, and is placed on the free roller 16 along the inclination of the receiving base 15. And the cleaning of the sheet pallet S is completed. In the present embodiment, the washed sheet pallet S removes water remaining by natural drying by sun drying. That is, the sheet pallet washing apparatus 1 in this embodiment not only realizes weight reduction and space saving of the apparatus by omitting drying means such as a dryer and a heater, but also uses natural energy for the drying process. In this respect, the device is excellent in terms of environment.

  The preferred embodiments of the present invention have been described above. However, the present invention is not limited to such specific embodiments, and various modifications can be made within the scope of the present invention described in the claims of the utility model registration. Deformation / change is possible.
