Description

  The present invention relates to a cleaning apparatus for cleaning an object to be cleaned such as a container with dirt.

  Conventionally, there are washing machines in which a plurality of nozzles rotate, but the sprinkler system as in Patent Document 1 is used. In this method, the cleaning liquid rotates in either direction due to the reaction of pressure injection, and for example, the rotation direction of each nozzle cannot normally be changed individually, so there is a limit to increasing the cleaning effect.

  Hereinafter, embodiments of the present invention will be described with reference to examples shown in the drawings. As shown in FIGS. 1 and 2, the cleaning apparatus 1 according to the present invention transports the object A to be cleaned on the support 2b and passes the support 2b so that the cleaning liquid B reaches the object A to be cleaned. A possible conveyor 2, an enclosure 3 that is provided on the conveyance path of the conveyor 2, surrounds the object A to be cleaned with a predetermined space, and protrudes to the inside of the enclosure 3 to be rotatable and can be rotated with respect to the object A to be cleaned The ejection units 41 to 44 and the ejection units 41 to 44 which are provided so that the cleaning liquid B can be ejected and are located at a plurality of locations (4 locations in this example) corresponding to different parts of the object A to be cleaned are separated from each other and independently of each other. The number of direct drive type injection unit rotation motors 51 to 54 corresponding to the number of injection units 4 to be rotated, and the controller that gives the rotation number, rotation direction, rotation pattern, and other drive conditions of the injection unit rotation motors 51 to 54 6 (control unit) and each injection unit 4 Includes a cleaning liquid supply unit 7 for pumping cleaning liquid B in ~ 44, a cleaning liquid recovery section 8 for collecting the dirty cleaning solution i.e. waste C after washing, the.

  Specifically, the conveyor 2 is composed of a chain conveyor that is wound around a plurality (two in this example) of chain sprockets 2a by connecting roller chains 2b (see FIG. 3). Two sets are provided, one on each of the left and right sides of the direction (see FIG. 2). The chain conveyor 2 is driven by a conveying motor 2c, and the roller chain 2b forms a support part on which the object A to be cleaned is placed.

  As shown in FIG. 2, the enclosure 3 is formed in a tunnel shape that forms a closed cross section that encloses the conveyance path in the middle of the conveyance path of the chain conveyor 2. Specifically, the enclosure 3 includes front and rear inlets 3I and 3E, and has a ceiling wall 31 and a bottom wall 32, and side walls 33 and 34 on both left and right sides in the transport direction.

  The injection parts 41 to 44 are respectively provided inward from the ceiling wall 31, the bottom wall 32, and the side walls 33 and 34 on both sides, and the injection part rotation motor is coaxially corresponding to the injection parts 41 to 44 on a one-to-one basis. 51-54 are arrange | positioned on the outer side of the ceiling wall 31, the bottom wall 32, and the side walls 33 and 34 of both sides, respectively. Each of the injection units 41 to 44 is individually rotated independently by the corresponding injection unit rotation motors 51 to 54 to inject the cleaning liquid B onto the object A to be cleaned. Since the chain conveyor 2 is connected to the roller chain 2b on both sides in the transport direction, the cleaning liquid B sprayed from the lower spraying part 42 can reach the object A to be cleaned through the roller chain 2b.

  In the cleaning liquid supply unit 7, when the pump 7b is driven by the rotation of the pump motor 7a, the cleaning liquid B pumped from the cleaning liquid tank 7c is distributed to the four injection units 41 to 44 via the electromagnetic valve 7d and the cleaning liquid supply unit pipe 7e. Supplied.

  As shown in FIG. 1 and FIG. 2, the object to be cleaned A is conveyed by the chain conveyor 2 and enters from the entrance 3I of the enclosure 3 until it exits from the exit 3E (or stops in the enclosure 3). In this state, the cleaning liquid B is sprayed onto the object A to be cleaned from the plurality of spraying units 41 to 44 rotated by the plurality of spraying unit rotating motors 51 to 54. However, there is a case where the back of the enclosure 3 is a dead end and enters from the entrance 3I and exits from the entrance 3I. In this case, the conveyance motor 2c rotates in reverse at a predetermined timing.

  The bottom wall 32 of the enclosure 3 is formed with an inclined portion 32 a that is inclined so as to become lower toward the downstream side in the transport direction and guides the waste liquid C to the outside of the enclosure 3. The cleaning liquid recovery unit 8 includes a recovery tank 8a that recovers the waste liquid C that flows to the outside of the enclosure 3 by the inclined portion 32a, and a recovery drain 8b that discharges the waste liquid C in the recovery tank 8a. Note that the waste liquid C discharged from the collected drain 8b is removed by a dirty water treatment apparatus (not shown) and reused as the cleaning liquid B.

  As shown in FIG. 2 and FIG. 3, the controller 6 performs the rotation number, rotation direction (forward / reverse switching), rotation pattern for each of the upper, lower, left, and right injection unit rotation motors 51 to 54. (Continuous rotation, intermittent rotation, alternate rotation, pause, etc.) An operation command signal for giving other driving conditions is output. As a result, the upper, lower, left, and right injection sections 41 to 44 rotate independently of each other. In addition, the controller 6 outputs an operation command signal that gives conveyance conditions such as rotation speed, forward / reverse rotation, and stop to the conveyance motor 2c, and also supplies the cleaning liquid B to the pump motor 7a and the electromagnetic valve 7d. An operation command signal for supplying supply conditions such as supply amount and distribution amount is output. These command signals may be programmed in advance, or an operator may input commands each time using buttons or the like.

  Thus, the control unit (controller 6) outputs an operation command signal that gives a driving condition for cleaning the object to be cleaned A to each of the plurality of injection unit rotating motors (51 to 54). The plurality of injection units (41 to 44) are rotationally controlled separately and independently of each other. The control unit (controller 6) outputs an operation command signal for giving an operating condition to the transport motor (2c), the pump motor (7a), and the electromagnetic valve (7d), and performs control so as to enhance the cleaning effect. .

  As shown in FIGS. 1 to 3, when cleaning the object A to be cleaned in the cleaning apparatus 1, the controller 6 drives the transport motor 2 c to rotate the chain conveyor 2 in the transport direction, so that the roller chain 2 b The object A to be cleaned is transported into the enclosure 3. At the same time, the controller 6 drives the upper, lower, left, and right injection unit rotating motors 51 to 54, and independently controls the upper, lower, left, and right injection units 41 to 44 independently. The pump motor 7a and the electromagnetic valve 7d are operated while continuously rotating in this direction at a predetermined number of revolutions, and the cleaning liquid B is injected from the injection units 41 to 44 onto the object A to be cleaned. The waste liquid C after the object to be cleaned A is cleaned is recovered by the cleaning liquid recovery unit 8 from the inclined portion 32 a formed on the bottom wall 32 of the enclosure 3.

  As shown to FIG. 4A, each injection part 41-44 is provided in the front-end | tip part of the rotating tube 4a rotatably supported by the enclosure part 3 (refer FIG. 2, FIG. 3), and the rotating tube 4a. 4a and a rotating nozzle 4c that rotates integrally. The output shafts 5a of the injection unit rotary motors 51 to 54 are coaxially connected so as to drive the rotary tube 4a. On the other hand, the cleaning liquid supply unit 7 is provided so as to intersect with the rotary tube 4a (orthogonal in the figure), and includes a cleaning liquid supply tube 7e that supplies the cleaning liquid B to the rotary tube 4a, a cleaning liquid supply tube 7e, and the rotary tube 4a. And a rotary joint 7f that connects the cleaning liquid B to communicate with each other.

  Specifically, the rotary joint 7f is fixed to the outer periphery of the rotating tube 4a and rotates integrally with the rotating tube 4a. The rotary joint 7f is concentric with the inner tube 7g and has a larger diameter than the inner tube 7g, and the cleaning liquid supply tube 7e. An outer cylinder 7h fixed to the tip of the inner cylinder, a plurality of (two rows in the figure) ball rows 7i that can roll between the inner cylinder 7g and the outer cylinder 7h, and an inner cylinder 7g inside each ball row 7i. And an annular seal 7j that closes between the outer cylinder 7h. A plurality of holes 4b are formed on the peripheral surface of the rotary tube 4a at predetermined intervals so as to allow the cleaning liquid B to flow in communication with the cleaning liquid supply pipe 7e. Therefore, when the output shaft 5a of the injection unit rotating motors 51 to 54 is driven, the rotating tube 4a (and the rotating nozzle 4c) can smoothly rotate via the rotary joint 7f with respect to the cleaning liquid supply tube 7e in a fixed state. The cleaning liquid B flows from the cleaning liquid supply pipe 7e through the hole 4b into the rotary pipe 4a and is ejected from the rotary nozzle 4c.

  Thus, since the injection parts 41-44 are driven separately and independently by the injection part rotation motors 51-54, the drive condition suitable for the to-be-cleaned object A can be set. Moreover, since the injection parts 41-44 are directly driven by the output shaft 5a of the injection part rotation motors 51-54, the control conditions can be set (or changed) by the controller 6 quickly. For example, a food container is carried on the roller chain 2b as the object to be cleaned A, and the cleaning liquid B is sprayed from the upper, lower, left, and right spraying portions 41 to 44 to clean the inner and outer surfaces of the container (see FIG. 3).

  Two inner and outer circular injection plates 4d and 4e formed with a large number of injection holes 4f penetrating the tip of the rotary nozzle 4c are orthogonal to the rotation axis and spaced apart by a predetermined distance in the rotation axis direction. Are arranged. Further, at least one of the injection plates 4d and 4e (for example, the outer injection plate 4e) is provided to be rotatable about the rotation axis. When the phases of the ejection holes 4f of the ejection plates 4d and 4e are aligned, the cleaning liquid B is ejected in the direction of the rotation axis of the rotary nozzle 4c, but the ejection direction is changed by rotating the ejection plate 4e and shifting the phase of the ejection holes 4f. (FIG. 4A virtual arrow state).

  FIG. 4B shows another example of the connection between the injection unit and the cleaning liquid supply unit. Similarly to FIG. 4A, each of the injection units 41 to 44 in FIG. 4B also has a rotating tube 4a rotatably supported by the enclosure 3, and a rotating nozzle that is provided at the tip of the rotating tube 4a and rotates integrally with the rotating tube 4a. 4c. Specifically, a fixed base 9 is fixed to the enclosure 3, and a housing 9 a and a motor base 9 d are fixed to the fixed base 9. The rotary tube 4a is rotatably supported by the housing 9a via an O-ring 9b and an oil seal 9c. On the other hand, the injection base rotating motors 51 to 54 and the transmission case 9e are attached to the motor base 9d, and the motors 51 to 54 rotate the rotary tube 4a via a transmission mechanism in the transmission case 9e. In this embodiment, a bevel gear or the like is used for the transmission mechanism, and the output shafts of the motors 51 to 54 and the rotary tube 4a are connected in an intersecting manner (for example, in an orthogonal manner).

  A plurality of (for example, four) rotating arms 4g projecting from the rotating tube 4a in a cross shape (orthogonal shape in the figure) and radially are connected to the distal end portion of the rotating tube 4a. The tip of each rotating arm 4g is connected to the rotating nozzle 4c via an elbow 4h, and the cleaning liquid B is ejected from each rotating nozzle 4c in the axial direction of the rotating tube 4a. Since the rotary nozzle 4c is provided at the tip of the rotary arm 4g, the cleaning liquid B can be ejected over a wide range. In addition, the ejection direction from the rotating nozzle 4c can be changed by changing the mounting angle among the rotating arm 4g, the elbow 4h, and the rotating nozzle 4c. Moreover, although the connection position of each rotary arm 4g with respect to the rotary tube 4a is shifted in the axial direction of the rotary tube 4a in FIG. 4B, it may be connected radially at the same axial position.

  The cleaning liquid supply unit 7 is provided so as to intersect with the rotary tube 4a (orthogonal in the figure), and the cleaning liquid supply tube 7e that supplies the cleaning liquid B to the rotary tube 4a, the cleaning liquid supply tube 7e, and the rotary tube 4a are connected to the cleaning liquid. And a rotary joint 7f connected so that B communicates. The rotary joint 7f has a structure similar to that shown in FIG. 4A. In addition, 4i is a socket which connects the rotary tube 7k of the rotary joint 7f and the rotary tube 4a of the injection parts 41-44. Reference numeral 9f denotes a cover body that also serves as a detent for preventing the stationary part such as the cleaning liquid supply pipe 7e from rotating with the rotating parts such as the rotary pipes 4a and 7k, and is attached to the transmission case 9e via the intermediate base 9g. It has been.

  FIG. 5 shows another embodiment of the rotating nozzle. As shown in FIG. 5 (A), a swing-type rotary nozzle 4c 'that precesses (purges) by the jetting part rotation motors 51 to 54 and the swing mechanism 4a' may be used. In FIG. 5B, a plurality of injection parts 4c2 are provided in a horizontal pipe part 4c1 extending in the horizontal direction from the rotary pipe 4a, and this whole rotates (turns). Both are so-called sprinkler systems, but are not rotated by the reaction of injection as in the prior art, but the injection units 41 to 44 are rotated by the injection unit rotation motors 51 to 54 separately and independently of each other. is there.

  Next, in the cleaning apparatus 1 shown in FIG. 6, the enclosures 3, 13, and 23 are installed at a plurality of locations (three locations in the figure) along the transport path of the conveyor 2. Of these, in the first enclosure 3 located on the most upstream side of the conveyor 2, for example, water is sprayed from the first injection unit 4 to perform rough cleaning, and in the second enclosure 13 located on the downstream side thereof, For example, the main cleaning is performed by injecting detergent from the second injection unit 14. In the third enclosure 23 located on the most downstream side, for example, water is injected from the third injection unit 24 to perform rinsing cleaning. Done. Further, a drying chamber 33 is provided downstream of the third enclosure 23, and a drying device 34 for drying the cleaned object A is provided in the drying chamber 33. The length of the cleaning line can be adjusted according to the degree of contamination, and the processing after cleaning can be performed efficiently.

  Further, in the cleaning apparatus 1 shown in FIG. 7, the enclosure 3 provided on the transport path of the roller conveyor 2e (conveyor) that transports the object A to be cleaned is disposed on the upper side and the lower side of the object A to be cleaned. The cleaning liquid B is jetted from the two jetting parts 41 and 42 thus cleaned. When the object to be cleaned A is a relatively flat part or the like such as a cylinder head, a relatively low cost cleaning device can be provided.

In other words, in the case of a simple cleaning device in which the injection unit is disposed on the upper side and the lower side of the object to be cleaned,
A conveyor on which the object to be cleaned is placed and conveyed on the support part, and through which the cleaning liquid can reach the object to be cleaned;
An enclosure provided on a conveying path of the conveyor, surrounding the object to be cleaned with a predetermined space therebetween;
An injecting portion which is provided on the upper side and the lower side of the object to be cleaned, provided to protrude inside the enclosure and to be rotatable and capable of injecting a cleaning liquid to the object to be cleaned;
A direct drive type injection unit rotation motor corresponding to the upper and lower injection units, which rotate the injection units separately and independently from each other;
A control unit that gives the drive speed of the injection unit rotation motor, the rotation direction, the rotation pattern, and the like;
A cleaning liquid supply unit that pumps the cleaning liquid to each of the injection units;
A cleaning liquid recovery unit for recovering a dirty cleaning liquid after cleaning;
Will be provided.

  In FIG. 7, a sprocket 2d that is engaged with and driven by the roller chain 2b of the chain conveyor 2 used in FIG. 3 is provided, and a roller conveyor 2e is provided coaxially with the sprocket 2d. Therefore, when the conveyor motor 2c is driven to rotate the chain conveyor 2, the sprocket 2d is engaged with the roller chain 2b and the sprocket 2d and the roller conveyor 2e coaxial with the sprocket 2d are rotated together. The article A to be cleaned is transported on a roller conveyor 2e that forms a support portion.

  In this embodiment, the chain conveyor 2 has a function of transmitting power to the roller conveyor 2e, but does not have a function of conveying the object A to be cleaned (the roller conveyor 2e has a function of conveying the object A to be cleaned). It may be provided on either the left or right side in the transport direction. Further, the rotation direction of the chain conveyor 2 and the rotation direction (conveying direction) of the roller conveyor 2e are opposite to each other. Each of the injection units 41 and 42 is individually independently rotated by the corresponding injection unit rotation motors 51 and 52 to inject the cleaning liquid B onto the object A to be cleaned. Since the chain conveyor 2 connects the roller chain 2b on one side in the conveying direction, and the roller conveyor 2e rotates at a fixed position, the cleaning liquid B sprayed from the lower spraying section 42 passes through the roller chain 2b and the roller conveyor 2e. The object to be cleaned A can be reached.

  In the above description, the mounting position of the injection unit has been the ceiling wall, bottom wall, and side wall of the enclosure, but is not limited thereto. The conveyor may be other than a chain conveyor or a roller conveyor (for example, a wire, a rope, etc.).
