A conveyor motor (not shown) is associated with the conveyor 300 as a conveyor driving means for driving the conveyor 300. Also, the conveyor 300 is provided with containers 4
The container 400 is engaged with the hook at the bottom of the container 400.
A hook portion 301 is provided for transferring the. In addition, the hook portion 30 of this conveyor 300
Containers to be cleaned are located near cleaning room 10.
When the container is placed on the conveyor 300 in front of the container entrance 102 and the hook portion 301 is placed in a position where it can engage with the hook portion of the container, this is detected and a container placement signal is output. Limit switch as detection means (not shown)
is provided. The detection means for outputting this container placement signal is not limited to a limit switch, but may also be a photo switch.Also, after the operator places the container to be cleaned on the conveyor 300 in front of the entrance 102 of the cleaning chamber 100, the operator operates the container placement signal. It may also be a push button switch that is pressed by a person.

The container washer mainly includes a cleaning chamber 100 and a conveyor 300, and an example of the control means of this container washer is schematically shown in FIGS. 2, 3, and 4. Figure 2 shows the drive circuit of the conveyor motor, inlet door motor, outlet door motor, wash water pump motor, and finishing water pump motor mentioned above, and Figures 3 and 4 show the drive circuit of Figure 2. A relay circuit for control is shown. FIG. 5 further shows the timing of the operation of each part of the washing machine by these drive circuits and relay circuits.

First, the entrance door 10 before the washing machine starts operating.
1 and the original position of the exit door 103 will be explained assuming that they are at the rising end. When the inlet door 101 is at the rising end, the limit switch LS ₄ associated with it is closed, and when the exit door 103 is at the rising end, the limit switch LS ₆ associated therewith is closed, thus relays R ₄ and R ₆ respectively. are energized and their normally open contacts CR ₄₁ and CR ₆₁ are closed. In addition, a relay R ₈ is energized upon completion of the draining operation of the drainer 200, which will be described later.
The normally open contact CR ₈ is closed. In this state, when the operator closes start switch SW ₁ to start cleaning, relay R ₇ is energized,
Its self-holding contact CR ₇₁ is closed, making the relay R ₇ self-holding, and at the same time its normally open contact CR ₇₂ is closed, creating a start-holding condition for the conveyor. After this, the operator should clean the container 4.
When 00 is placed at a predetermined position at the starting end of the conveyor 300, the photo switch PS as a container placement detection means is closed, relay R ₁ is energized, and its normally open contact CR ₁ is closed, so that electromagnetic switch MS ₁ is activated. energized, its contacts CMS ₁ are closed and the conveyor motor is activated. Therefore, conveyor 300
is driven to move the container 400 into the cleaning room 10.
Start transporting towards 0. In this way, container 40
0 is transferred into the cleaning chamber 100 through the fully opened entrance 102 of the entrance door 101, and when the container reaches the home position, the limit switch _LS1 serving as the container home position detection means is closed and the relay _R2 is energized. Then, its normally closed contact CR ₂₁ is opened, the electromagnetic switch MS ₁ is deenergized, the contact CMS ₁ is opened,
The conveyor motor is stopped and therefore conveyor 3
00 will also stop and the container 400 will be held in its container position. At the same time, normally open contacts CR ₂₂ and CR ₂₃ of relay R ₂ are closed, so that electromagnetic switches MS ₂ and MS ₃ are energized, respectively (see FIG. 4). Therefore, contact CMS ₂₁ of electromagnetic switch MS ₂ is closed, normally closed contacts CMS ₂₂ and
CMS ₂₃ is opened and entrance door motor 105 is driven in the direction of closing entrance door 101. Further, the contact CMS ₃₁ of the electromagnetic switch MS ₃ is closed, and the exit door motor 106 is driven in the direction of closing the exit door 103. In this way, when the entrance door 101 is completely lowered and becomes fully closed, the limit switch LS ₃ associated with it is closed, and the exit door 101 is closed.
03 is fully lowered to the fully closed state, its associated limit switch LS ₅ is closed, and therefore relays R ₃ and R ₅ are energized, respectively.
Since their normally closed contacts CR ₃₁ and CR ₅₁ are opened, respectively, the inlet door motor 105 and the outlet door motor 10
6 is stopped, and the entrance door 101 and the exit door 1
03 is in a fully closed state. At the same time, normally open contact CR ₃₂ of relay R ₃ and normally open contact CR ₅₂ of relay R ₅ are closed, so that the operation of cleaning timer T ₁ is started (see FIG. 4).

Predetermined time T ₁ from the start of operation of cleaning timer T ₁
Until that normally closed contact CT ₁₁ is closed, the normally open contact
CT ₁₂ is open. Therefore, first, the electromagnetic switch
MS ₄ is energized and its contacts CMS ₄ are closed;
The cleaning water pump motor is activated, and the container 400 is stationary at a fixed position from the injection nozzle of the cleaning water injection nozzle array provided in the cleaning chamber 100.
Washing water is sprayed onto the surface to perform washing, so-called rough washing. After such rough cleaning continues for T ₁ hour, the normally closed contact CT ₁₁ opens due to the operation of the cleaning timer T ₁ , the electromagnetic switch MS ₄ is deenergized, the cleaning water pump motor is stopped, and the cleaning starts. Water injection is stopped. At the same time, the normally open contact CT ₁₂ is closed and the finishing timer T ₂ is started (see FIG. 4).

The normally closed contact CT ₂₁ is closed and the normally open contact CT ₂₂ is open until a predetermined time T ₂ from the start of the finishing timer T ₂ . Therefore, first of all, the electromagnetic switch MS ₅ is energized, its contacts CMS ₅ are closed, the finishing water pump motor is activated, and the cleaning chamber 1 is activated.
Container 40 stationary at the container fixed position from the injection nozzle of the finishing nozzle array provided in 00
Finishing water is sprayed onto the 0, and following the rough cleaning using the cleaning water nozzle described above, a more complete cleaning finish, so-called rinsing, is performed. still,
The control circuits of FIGS. 2, 3, and 4 do not include means for controlling the supply of steam to the steam injection nozzle array provided in the cleaning chamber 100. If a _steam injection nozzle array such _as
It can be made to eject inward. After such rinsing has continued for T ₂ hours, the normally closed contact CT ₂₁ is opened by the operation of the finishing timer T ₂ and the electromagnetic switch MS ₅ is deenergized,
The finishing water pump motor is stopped and finishing water injection is stopped. At the same time, the normally open contact CT ₂₂ is closed and the drain time timer T ₃ is started (see FIG. 4).

A predetermined time T ₃ from the start of the operation of the draining time timer T ₃ (this time T ₃ is the draining device 2 described later
00, and is selected to be equal to or somewhat longer than the time from this time to the completion of the draining process), then the draining time timer
The action of T ₃ closes its normally open contacts CT ₃₁ and CT ₃₂ . Then, electromagnetic switch MC ₂ and
MC ₃ is energized and the respective normally closed contact CMC ₂₂
and CMC ₃₂ are opened and normally open contacts CMC ₂₃ and
CMC ₃₃ is closed and at the same time contacts CMC ₂₁ and
CMC ₃₁ is closed. Therefore, the entrance door motor 1
05 is driven in the direction to open the entrance door 101, and the exit door motor 106 is driven in the direction to open the exit door 103. Thus, when the entrance door 101 is fully raised and fully open, the limit switch LS ₄ associated with it is closed, and
When the exit door 103 is fully raised to the fully open condition, its associated limit switch LS ₆ is closed, thus energizing the relays R ₄ and R ₆ , respectively, to close their normally open contacts CR ₄₁ and R 6, respectively.
CR ₆₁ is closed. Meanwhile, by this time, due to the operation of the drain time timer T ₃ , its normally closed contact CT ₃₃
is opened and relay R ₂ is deenergized, so its normally closed contact CR ₂₁ is closed. Therefore, the electromagnetic switch MS ₁ is energized again and its contact CMS ₁ is closed, and the conveyor motor is driven again to drive the conveyor 300 again and start transporting the cleaned container 400 again. In this way, the container 400 is transferred from the cleaning chamber 100 to the draining position where the drainer 200 is located through the fully opened outlet 104 of the outlet door 103.

Next, the operation of draining the container 400 by the draining device 200 as described above will be explained with particular reference to the schematic plan view of FIG. 9.

First, the draining device 200 further includes 12 limit switches at predetermined positions as control means for the moving drive means 240 and the expansion drive means 250.
LS ₁₁ to LS ₂₂ are provided. These limit switches LS ₁₁ to _{LS 22} are connected to the main motor for moving the main moving table 241 and the auxiliary moving table 251.
It is incorporated into the control circuit to control the operation and stop of the sub-motor for moving the motor. The configuration of this control circuit will not be described in detail here since it can be easily designed by those skilled in the art from the control examples described below.

Here, the container 400 to be drained is the ninth container.
As shown schematically in the figure, there are thick pillars 4 at the four corners.
06, and therefore, the internal width of the container 400 is narrowed by the support 406 at the front and rear entrance portions.

First, in the draining device 200 in the retracted position shown in FIG. 9, the operator presses the start switch of the control circuit to start the draining process, or
Alternatively, when the main motor is driven to rotate in the normal direction by a signal from the detection means that detects that the container 400 has reached the draining position, the main movable table 24
1 is moved in the forward direction of arrow A at a speed of, for example, 40 mm/sec. At this time, the protruding rod 24

51 and the expansion rod 252 also move together with the main moving table 241, the draining spatula portion 2 provided at the tip of the protruding rod 242 and the expansion rod 252
20 and 230 are also moved forward in their closed state to the positions indicated by the reference numerals. At this position, the most extreme part of the spatula member 226 is at its apex and about to exceed the support column 406 on the front side of the container 400. When reaching the position, the working protrusion 241 provided on the main moving table 241
Limit switch LS ₁₁ is closed by A.
When the limit switch LS ₁₁ is closed, the main motor is stopped via the control circuit, the movement of the main moving table 241 is stopped, and at the same time, the sub motor is driven in the normal direction, thereby moving the auxiliary moving table 251 forward in the direction of arrow B. direction at a speed of, for example, 45 mm/sec. At this time, the expansion rod 252 is also moved together with the auxiliary moving table 251. However, the main moving table 241 is stopped and the protruding rod 242
has also stopped. Therefore, since only the second and third spatula support pieces 222 and 223 are pushed forward, the first and fourth spatula support pieces 221 and 224 are moved outward in the direction of arrow C ( (See FIG. 8), the spatula member 226, as indicated by the reference numeral, is brought into a fully expanded state. In this state, the spatula member 226 is attached to the container 400.
It is expanded to the maximum extent to cover the entire width of the interior. When reaching this position, the auxiliary moving platform 2
The limit switch LS 12 is closed by the operating protrusion 251A provided on the limit switch LS ₁₂ . When limit switch LS ₁₂ is closed, via the control circuit,

26 is advanced in its expanded state at the position indicated by the reference numeral. In this position, the spatula member 226 is at the top and in front of the column 406 on the rear side of the container 400.
When reaching the position, the limit switch is activated by the operating protrusion 241A provided on the main moving table 241.
LS ₁₃ is closed. When the limit switch LS ₁₃ is closed, the main motor is stopped via the control circuit, the movement of the main moving table 241 is stopped, and at the same time, the sub motor is again driven in the normal direction, thereby causing the auxiliary moving table 251 to move forward again. be moved to. At this time, the expansion rod 252 is also moved together. However, the main moving table 241 is stopped and the protruding rod 242 is also stopped. Therefore,
Since only the second and third spatula support pieces 222 and 223 are pushed further forward, the first and fourth spatula support pieces 221 and 224 are now pushed forward.
is moved inward in the direction of arrow C (see FIG. 8), and the spatula member 226 as indicated by the reference numeral
is kept closed. In this state, the spatula member 226 has a width that allows it to pass between the inner sides of the support columns 406 of the container 400, and this width may be the same as in the position. When reaching this position, the auxiliary moving table 251

Since the auxiliary moving table 251 and the expansion rod 252 also move rearward together with the main moving table 241, the spatula member 226 is moved backward while remaining in the closed position, and the rear support column 406 of the container 400 is moved backward. It reaches the position indicated by the reference symbol where the apex is to be crossed. When the position is reached, the limit switch LS ₁₆ is closed by the operating protrusion 241B provided on the main carriage 241. When the limit switch LS ₁₆ is closed, the reverse drive of the main motor is stopped via the control circuit, the backward movement of the main moving table 241 is stopped, and at the same time, the sub motor is driven in the reverse direction, so that the auxiliary moving table 251 moves as shown in the arrow B is moved backwards. At this time, the expansion rod 25
2 is also moved backwards. However, the main moving table 241 is stopped and the protruding rod 242 is also stopped. Therefore, only the second and third spatula support pieces 222 and 223 are pulled rearward, so the first and fourth spatula support pieces 221 and 224 move outward in the direction of arrow C again. (see FIG. 8), and the spatula member 226 is fully expanded, as indicated by the reference numerals. In this state, the spatula member 226 is expanded to the maximum so as to cover the entire width inside the container 400. When this position is reached, the limit switch LS ₁₇ is closed by the operating protrusion 251B provided on the auxiliary moving table 251. When the limit switch LS ₁₇ is closed, the sub motor is stopped via the control circuit, and the auxiliary moving table 251
movement stops, and at the same time, the main motor is driven in the reverse direction again, thereby moving the main moving table 241 in the rear direction again. At this time, the protruding rod 242, the auxiliary moving table 251 and the expanding rod 25
2 also moves together with the main moving table 241, the spatula member 226 is moved backward while remaining in the expanded state at the position, and comes to the position indicated by the reference numeral. In this position, the spatula member 226 is at the top and the container 400 is
This is the position in front of the pillar 406 on the front side. When this position is reached, the limit switch is activated by the operating protrusion 241B of the main moving table 241.
LS ₁₈ is closed. When the limit switch LS ₁₈ is closed, the main motor is stopped via the control circuit, the movement of the main moving table 241 is stopped, and at the same time, the sub motor is driven in the reverse direction again, thereby causing the auxiliary moving table 251 to move backward again. be moved. At this time, the expansion rod 252 is also moved together. However, the main moving table 241 is stopped and the protruding rod 242 is also stopped. Therefore,
Since only the second and third spatula support pieces 222 and 223 are pulled further rearward, the first and fourth spatula support pieces 221 and 224 are moved inward in the direction of arrow C (see FIG. ), the spatula member 226 is brought into a closed state, as indicated by the reference numeral. In this state, the spatula member 226 has a width that allows it to pass between the insides of the columns 406 of the container 400, and this width is the same as in the position. When reaching this position, the working protrusion 251B of the auxiliary moving table 251
limit switch LS ₁₉ is closed by .
When the limit switch LS ₁₉ is closed, the sub motor is stopped via the control circuit, the movement of the auxiliary moving table 251 is stopped, and at the same time, the main motor is driven in the reverse direction again, thereby moving the main moving table 251 in the rear direction again. I am made to do so. At this time, the protruding rod 242, the auxiliary moving table 251 and the expanding rod 2
52 also moves together with the main carriage 241, the spatula member 226 is retracted while remaining in the closed position and returns to its original position indicated by the reference numeral. When reaching the original position, the limit switch LS ₂₀ is closed by the operating protrusion 241B provided on the main moving carriage 241. limit switch
