  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a cleaning process diagram of an in-container cleaning apparatus according to an embodiment of the present invention. As shown in the figure, the in-container cleaning apparatus of FIG. 1 performs only two steps of a single cleaning process S1 and a drying process S2, and is more than the conventional cleaning apparatus shown in FIGS. It is characterized in that the number of processes can be greatly reduced. As will be described later, in the present embodiment, since the cleaning liquid is also discharged in parallel with the cleaning process S1, unlike the cleaning process S1, it is not necessary to provide the cleaning liquid discharge process separately from the cleaning process S1.

  2-6 is a figure which shows the structure of the washing | cleaning apparatus in a container which concerns on one Embodiment of this invention, This embodiment is demonstrated based on these figures. In these drawings, in order to make the structure easy to understand, the container 2 to be cleaned and the receiving container 3 are illustrated in a transparent color.

  2 is an external view of the in-container cleaning apparatus 1, FIG. 3 is a plan view showing a state before the container 2 to be cleaned is gripped, and FIG. 4 is a plan view showing a state in which the container 2 to be cleaned is gripped and rotated. 5 is a plan view showing the operation of the rotation mechanism 7 described later, and FIG. 6 is a perspective view of the periphery of the operation member 17 described later.

  As shown in these drawings, the in-container cleaning apparatus 1 includes a receiving container 3 that can store a container 2 to be cleaned with the opening portion down, and an opening of the container 2 to be cleaned from the receiving container 3. A cleaning pipe 4 extending upward, an injection unit 5 that is attached to the cleaning pipe 4 and injects a high-pressure liquid toward the inner wall of the container 2 to be cleaned, and a waste liquid duct 6 that is attached to the bottom or side of the receiving container 3 A rotating mechanism 7 that rotates the container 2 to be cleaned within the receiving container 3.

  An annular member 8 is attached inside the receiving container 3 at a position higher than the bottom surface. The outer peripheral portion of the annular member 8 is joined to the inner wall of the receiving container 3, and a circular groove 8 a having a smaller diameter than the inner peripheral surface of the receiving container 3 is formed on the surface of the annular member 8. The end of the opening of the container 2 to be cleaned can be fitted into the groove 8a. The container 2 to be cleaned is rotated with the end of the opening fitted in the groove 8a. For this reason, depending on the material of the container 2 to be cleaned and the groove 8a, the opening of the container 2 to be cleaned may be damaged by friction. Therefore, the surface of the groove 8a may be covered with an elastic material such as rubber.

  As described above, since the end of the opening of the container 2 to be cleaned is fitted into the groove 8a, only the container 2 to be cleaned having the same opening as the diameter of the groove 8a can be cleaned. Therefore, a plurality of grooves 8a having different diameters may be formed in the annular member 8 in advance. Alternatively, a plurality of annular members 8 each having a groove 8 a having a different diameter may be prepared, and the corresponding annular member 8 may be attached to the receiving container 3 in accordance with the diameter of the opening of the container 3 to be cleaned. .

  Since the annular member 8 is mounted above the bottom surface of the receiving container 3, the liquid used for cleaning in the container to be cleaned 2 flows below the annular member 8 in the receiving container 3, and the waste liquid duct 6. It is discharged to the outside through. For this reason, the annular member 8 needs to be provided above the waste liquid duct 6.

  For example, the cleaning tube 4 extends upward from the bottom surface of the receiving container 3 through the annular member 8 and the opening of the container 2 to be cleaned, and the tip thereof is the bottom surface of the container 2 to be cleaned (uppermost part). ) Located nearby. Injecting sections 5 are attached to a plurality of locations of the cleaning pipe 4, and each injecting section 5 includes a large number of nozzles 5 a, and high-pressure liquid (for example, water) is directed from the nozzles 5 a toward the inner wall of the container 2 to be cleaned. Be injected. In this way, a high-pressure pump (not shown) is provided at the base end of the cleaning pipe 4 in order to send the high-pressure liquid agent from below to above through the cleaning pipe 4.

  As will be described later, in the present embodiment, since the high-pressure liquid agent is injected from the injection unit 5 while rotating the container 2 to be cleaned, the injection unit 5 is not necessarily arranged evenly with respect to the inner wall surface of the container 2 to be cleaned. You don't have to. However, since the position of the bottom surface of the container 2 to be cleaned does not change even when the container 2 to be cleaned is rotated, the liquid is injected above the injection unit 5 so that a high-pressure liquid agent is injected onto the bottom surface of the container 2 to be cleaned. It is desirable to arrange the part 5.

  The rotating mechanism 7 includes a gripping tool 11 that grips the container 2 to be cleaned, a gripping tool connecting portion 12 that is connected to the proximal end of the gripping tool 11, an auxiliary tool 13 that supports an intermediate portion of the gripping tool 11, and an auxiliary Auxiliary tool connecting portion 14 connected to the base end of tool 13, gripping tool 11, gripping tool connecting portion 12, rotating tool 15 for rotating auxiliary tool 13 and auxiliary tool connecting part 14, and rotary shaft 15 for rotational driving A rotation drive unit 16 that controls the gripping tool 11, and an operation member 17 that controls the gripping operation of the gripping tool 11.

  The gripper 11 can grip the container 2 to be cleaned by operating the operation member 17. The gripping tool connecting portion 12 is inserted into the rotary shaft 15 and moves up and down along the rotary shaft 15 in accordance with the operation of the operation member 17. The auxiliary tool connecting portion 14 is fixed to the rotating shaft 15 and rotates together with the rotating shaft 15. Since the auxiliary tool 13 is connected to the auxiliary tool connector 14, the auxiliary tool 13 rotates when the auxiliary tool connector 14 rotates. Moreover, since the auxiliary tool 13 is also connected to the gripping tool 11, when the auxiliary tool 13 rotates, the gripping tool 11 also rotates. Furthermore, since the gripping tool 11 is connected to the gripping tool connecting portion 12, eventually, when the rotary shaft 15 rotates, the gripping tool 11, the gripping tool connecting portion 12, the auxiliary tool 13 and the auxiliary tool connecting portion 14 are adjusted accordingly. Will rotate together.

  The tip of the gripper 11 is covered with, for example, an elastic material so as not to damage the container 2 to be cleaned when the container 2 to be cleaned is gripped.

  A first urging member 18 is provided along the axial direction of the rotation shaft 15 below the bottom surface of the gripping tool connecting portion 12. Due to the biasing force of the first biasing member 18, the gripper connecting portion 12 moves up and down along the rotation shaft 15. More specifically, the gripping tool connecting portion 12 moves upward from the length when the first biasing member 18 is biased to the length when the biasing is released. As a result, when the urging is released, the gripping tool connecting portion 12 rises to a position where it is opposed to the operation member 17 and stops. Thereby, the operation member 17 is brought into contact with the gripping tool connecting portion 12 and does not protrude from the outer peripheral surface of the rotating shaft 15. That is, the movement of the operating member 17 protruding from the outer peripheral surface of the rotating shaft 15 is restricted by the gripper connecting portion 12.

  The operation member 17 is attached at two locations in the radial direction of the rotary shaft 15, and a second urging member 19 is provided between the operation members 17. When the operator presses both operation members 17 by hand, the second urging member 19 contracts, and the operation member 17 moves to the inside of the outer peripheral surface of the rotating shaft 15.

  As described above, the gripping tool connecting portion 12 moves up and down along the rotating shaft 15 by the biasing force of the first biasing member 18, but the operation member 17 protrudes from the outer peripheral surface of the rotating shaft 15. In this case, upward movement is restricted by the operation member 17. This is shown in FIGS. 5 (a) and 5 (b). In this case, the first urging member 18 is urged and the second urging member 19 is in a released state.

  When the operator presses the operating member 17 from the state of FIG. 5A and the operating member 17 does not protrude from the outer peripheral surface of the rotary shaft 15, the upward movement restriction of the gripping tool connecting portion 12 is released, The gripping tool connecting portion 12 moves upward by the biasing force of the first biasing member 18. Thereby, the gripping tool 11 moves in the gripping direction. This is shown in FIG. 5 (c) and FIG. 5 (d).

  Hereinafter, the cleaning and drying step S2 of the in-container cleaning device 1 according to the present embodiment will be described in more detail.

(Washing step S1)
First, the container 2 to be cleaned is positioned below the rotating mechanism 7 in an upside down state. At this time, the operation member 17 of the rotation mechanism 7 is in a state of protruding from the outer peripheral surface of the rotation shaft 15 (FIGS. 5A and 5B), and the gripping tool connecting portion 12 is moved upward by the operation member 17. Movement is restricted, the gripping tool 11 remains open, and no gripping operation is performed.

  Next, the operator presses the operation member 17 with a finger until the operation member 17 does not protrude from the outer peripheral surface of the rotating shaft 15. As a result, the restriction on the upward movement of the gripping tool connecting portion 12 is released, and the gripping tool connecting portion 12 is moved upward by the biasing force of the first biasing member 18 and is positioned opposite to the operation member 17. Stop (FIG. 5 (c) and FIG. 5 (d)). When the gripping tool connecting portion 12 moves upward, the auxiliary tool 13 presses the gripping tool 11 inward. Thereby, the gripping tool 11 grips the outer surface on the opposite side to the opening of the container 2 to be cleaned.

  When the gripping tool 11 grips the container 2 to be cleaned, when the rotating shaft 15 is rotated by the rotation driving unit 16, the auxiliary tool connecting portion 14 fixed to the rotating shaft 15 rotates together with the rotating shaft 15, and accordingly. The assisting tool 13 connected to the assisting tool connecting part 14, the gripping tool 11 connected to the assisting tool 13, and the gripping tool connecting part 12 connected to the gripping tool 11 rotate together. As a result, the container to be cleaned 2 rotates around the rotation axis 15.

  Along with the rotation of the container 2 to be cleaned, a high-pressure liquid agent is fed from the cleaning tube 4 and this liquid agent is sprayed from the spray unit 5 toward the inner wall of the container 2 to be cleaned. Thereby, even if the liquid agent is simply water, the deposits stuck to the inner wall of the container 2 to be cleaned can be removed cleanly by the rotation of the container 2 to be cleaned and the pressure of the water to be sprayed.

  Since the high-pressure liquid agent injected from the injection unit 5 automatically flows into the waste liquid duct 6 through the central portion of the annular member 8, the cleaning liquid is discharged in parallel with the above-described cleaning step S1.

  Although the cleaning step S1 is completed as described above, how long the cleaning time is continued may be determined based on past experience. Alternatively, the cleaning may be performed for a short time at first, and the operator may visually check the cleaning state in the container to determine whether or not the cleaning should be continued.

(Drying step S2)
When the cleaning is finished, the operator pushes the gripping tool connecting portion 12 downward, so that the operation member 17 protrudes from the outer peripheral surface of the rotary shaft 15, whereby the gripping tool connecting portion 12 is moved upward by the operating member 17. Is restricted, and the grasping tool 11 releases the grasping operation. In this state, the operator takes out the container 2 to be cleaned and visually confirms the internal cleaning state, and then attaches the pallet 31 and the support plate 35 to the bottom surface of the container 2 to be cleaned as in FIG. Further, the rotation shaft 46 is attached to the center portion of the support plate 35. Then, an air nozzle 49 is installed inside the container 2 to be cleaned, and the inner wall of the container 2 to be cleaned is dried by the air from the air nozzle 49.

  As described above, in the present embodiment, since the cleaning step S1 is completed in one step without being divided into a plurality of steps, the cleaning step S1 can be simplified and workability can be improved. In the cleaning step S1, since the cleaning liquid is discharged in parallel with the cleaning, there is no need to provide a separate cleaning liquid discharging step. Furthermore, since only one type of in-container cleaning apparatus 1 is used for the cleaning step S1, costs can be reduced and maintainability is improved.

  Moreover, in this embodiment, since the high-pressure liquid agent is sprayed onto the inner wall of the container 2 to be cleaned by the spray unit 5 while rotating the container 2 to be cleaned, a special cleaning liquid having an excellent cleaning action is used as the liquid agent. It is not necessary to use it, and a sufficient detergency can be obtained even with simple water. For this reason, the cleaning cost can be reduced.

  The effect of this embodiment mentioned above is acquired by the characteristic structure of the cleaning apparatus 1 in a container. That is, in a state where the end of the opening of the container 2 to be cleaned is fitted in the groove 8a in the receiving container 3 and the container 2 to be cleaned is rotated, a high-pressure liquid agent is sprayed on the inner wall of the container 2 to be cleaned, By allowing the waste liquid after washing to flow from the receiving container 3 to the waste liquid duct 6, even when paint or the like is spread on the inner wall of the container 2 to be washed, it can be removed cleanly by one washing.

  In the above-described embodiment, the cleaning of the paint container has been described in mind, but the container 2 to be cleaned is not limited to the paint. The present invention can be widely applied to cleaning of containers containing various materials. Depending on the type of the contents stored in the container, the type of cleaning liquid, the pressure at the time of jetting the liquid, the length of the cleaning time in the above-described cleaning step S1, the rotational speed at the time of cleaning the container 2 to be cleaned, the jet It is desirable to perform cleaning in an optimal state by variously adjusting the number and arrangement of the nozzles 5a in the apparatus.

  The aspect of the present invention is not limited to the individual embodiments described above, and includes various modifications that can be conceived by those skilled in the art, and the effects of the present invention are not limited to the contents described above. That is, various additions, modifications, and partial deletions can be made without departing from the concept and spirit of the present invention derived from the contents defined in the claims and equivalents thereof.
