Description

  The present invention relates to a cleaning apparatus devised mainly for efficiently and efficiently cleaning foods such as vegetables and a cleaning system incorporating the cleaning apparatus.

  As a conventional cleaning system of this type, an elevating rotary table is arranged on a base so that it can be raised and lowered and intermittently rotated in a plane perpendicular to the elevating direction. Four container support parts are provided at equal intervals in the rotation direction of the lifting / lowering table, and at least a loading station, a cleaning station, and a discharging station are set in the rotation direction of the lifting / lowering table corresponding to the lifting / lowering position of the basket container. In addition, a food cleaning system has been proposed in which a water tank with an upper surface opening containing cleaning water is provided in the cleaning station (Patent Document 1).

The above-mentioned cleaning system is intended to effectively clean food in a basket container by jetting pressurized air from a small hole in a pipe laid in a water tank to generate a jet jet or a bubble flow.
Although the applicant experimentally manufactured a cleaning system similar to the above, it was found that the momentum of the jet jet was hardly reached in the soot container because it was blocked by the bottom wall and the peripheral wall of the soot container.

Needless to say, a large number of water passage holes are formed at close intervals in the bottom wall and the peripheral wall of the dredger container, but the wall surface between the holes weakens the momentum of the jet water flow more than expected.
The bubble flow was the same, and the momentum of the bubbles entering from the hole of the container did not produce a water flow enough to stir the food in the container, and it was found that the desired cleaning effect could not be obtained. .

JP 2001-78740 A

  The present invention generates a large rotational flow in the water in the container by jetting the high-pressure water into the container from above in the container, and strikes the high-pressure water against the water surface or food. It is intended to clarify a cleaning device that can effectively clean foods in a short time and a cleaning system incorporating the cleaning device.

  The food washing apparatus according to claim 1 includes a water tank (6) having an upper surface opening, a tub container (7) immersed in the water tank (6), and high-pressure water jetted from above the jar container (7) into the water tank (6). The nozzle (93) of the high pressure water injection device (9) is rotatable, and the nozzle (93) is provided with a rotating means (97). 93) is characterized in that high-pressure water is jetted in a circular path into the container (7).

  A second aspect of the present invention is the food washing apparatus according to the first aspect, wherein the nozzle (93) is disposed so as to be retractable from the upper side of the water tank (6) to the side or further upward.

  Claim 3 is the food washing apparatus according to claim 1 or 2, wherein the tip of the high-pressure water injection pipe (95) of the nozzle (93) is connected to the water surface of the water tank (6). The rotating means (97) is formed by inclining a little in the direction opposite to the rotation direction and facing downward.

  According to a fourth aspect of the present invention, in the food washing apparatus according to the first aspect, the rotating means (97) of the nozzle (93) is a motor connected to the nozzle (93).

  The food washing system according to claim 6 is provided with a lifting / lowering table (3) that can be moved up and down on the base (1) and intermittently rotatable in a plane orthogonal to the lifting and lowering direction. Three or more support portions (4) for detachably supporting the container (7) are provided in the rotational direction of the lifting / lowering rotary table (3) at equal intervals, and the base (1) is positioned at the lifting / lowering position of the basket container (7).

Since the food washing apparatus according to claim 1 injects high-pressure water from the nozzle (93) into the container (7) immersed in the water tank (6) and generates a rotating water flow by the injection of the high-pressure water, Together with the food, the food can be efficiently washed by rotating in the container (7).
Further, since the nozzle (93) itself rotates in response to the injection of the high-pressure water, the injection position of the high-pressure water with respect to the water surface continuously changes along a circular locus. For this reason, as in the case where the injection position of high-pressure water is fixed, the flow of food does not stagnate on the upstream side of the water surface in the water tank (6) with respect to the injection position of high-pressure water. Smoothes the flow of food and eliminates washing spots in food.

The lock means (5) is in a position where it hits the lever (52) (52).
That is, immediately before the dredge container (7) lands on the discharge conveyor (8), the lock of the dredge container (7) by the presser frame (42) is released. Even if the dredger container (7) lands, the receiving arm (41) is lowered a little further, so that the dredger container (7) can be smoothly and automatically discharged from the discharge station S3 by continuously operating the conveyor (8). .

As shown in FIG. 6, the water tanks (6) and (6) installed in the washing station Sa and the rinsing station Sb are open at the top and formed in a slightly inverted cone shape corresponding to the side wall (70) of the basket container (7). The size of the container (7) can be accommodated in a state where there is not much room.
The water tank (6) is provided with a bowl-shaped overflow tank (63) around the opening edge.
The height of the upper end of the water tank (6), that is, the height of the inner peripheral wall (63a) of the overflow tank (63) is determined by the water tank (7) supported by the water container support part (4) as described later. In the state immersed in 6), it is the same as or slightly higher than the height of the presser part (42c) of the support part (4).
A drain port (63c) extends shortly from the outer peripheral wall (63b) of the overflow tank (63) to the outside, and a flange (63d) projects from the tip of the drain port (63c).

At both ends of the base (1), there are provided water storage tanks (64) and (64) for collecting drainage from the drain ports (63c) and (63c) of the overflow tanks (63) and (63). The water storage tank (64) is long in the direction orthogonal to the longitudinal direction of the base (1), that is, in the direction of the discharge conveyor (8). This is to shorten the length of the base (1) including the water storage tanks (64) and (64) as much as possible so that the installation space for the cleaning device can be reduced.
The water storage tank (64) is provided with a clean water supply pipe (66) for supplying clean water into the water storage tank (64) from the outside.

A filter (69) is provided in the water flow path from the overflow tank (63) to the pump (65).
The filter (69) of the embodiment is a bottomed cylindrical lint filter, and the opening edge of the filter is fitted into the drain port (63c) of the overflow tank (63) beyond the flange (63d), It is attached so as to be detachable by being tied up (not shown). In this way, attaching a lint filter to the drain outlet (63c) of the overflow tank (63) ensures that foreign matter such as vegetable debris mixed in the water discharged from the overflow tank (63) to the water storage tank (64) can be ensured. I can capture it. In addition, the filter can be easily and securely attached, the filter can be easily maintained, and the cost of capturing foreign matter can be kept low.

As shown in FIGS. 1 to 3, on the washing station S2, high-pressure water injection devices (9) and (9) for injecting high-pressure water from above into the two water tanks (6) and (6) on the station S2. Is deployed.
Each high-pressure water injection device (9) (9) has a swivel (91) at the upper end of a discharge pipe (67) (67) provided in a vertical direction with the lower part immersed in each of the water storage tanks (64) (64). The arm tube (92) is projected so as to be rotatable in a plane orthogonal to the discharge tube (67), the tip of the arm tube (92) is bent slightly downward, and the nozzle (93) is armed at the bent tip. The tube (92) is mounted so as to rotate freely in a plane orthogonal to the plane of rotation of the tube (92).
In the arm pipe (92) or the discharge pipe (67), as shown in FIG. 1, the nozzle (93) is located right above the center of the water tank (6), that is, right above the center of the dredger container (7). As shown in FIG. 2, the operating position is linked to switching means (not shown) that automatically switches from the upper position of the water tank (6) to a retracted position for retreating in the lateral direction.

The timing of switching the position of the nozzle (93) is as follows, when the dredger container (7) is put into the water tank (6) and when the dredger container (7) is taken out from the water tank (6). When the soot container (7) is immersed in the water tank (6), it is positioned directly above the soot container (7).
The nozzle position switching means may be configured as long as the nozzle (93) can be switched between the two positions described above.
A pump (65) is connected to the lower ends of the discharge pipes (67) and (67). The pump (65) operates when the nozzle (93) is in the operating position.
The tip (66a) of the clean water supply pipe (66) opens in the vicinity of the water intake port of the pump (65).

The nozzle (93) has two injection pipes (95) projecting laterally in opposite directions from the nozzle base (94) attached to the arm pipe (92) so as to freely rotate, and the tip of the injection pipe (95). Is bent downward. However, the tips of the two injection pipes (95) and (95) are not perpendicular to the water surface of the water tanks (6) and (6), but are slightly inclined in the counter-rotating direction with respect to the rotating direction of the nozzle (93).
When the downward tip of the arm tube (92) is positioned on the axis of the water tank (6), the tip of the injection pipe (95) (95) is the upper surface opening of the dredger container (7) immersed in the water tank (6). The high pressure water is in a position where the arc trajectory can be jetted within the range.

Accordingly, when high pressure water is injected from the injection pipes (95) and (95) into the water surface in the dredger container (7) from a slightly oblique direction, a rotating water flow is generated in the dredge container (7), and the nozzle (93) The arm tube (92) rotates around the downward tip by the reaction of the high-pressure water jet. That is, high-pressure water is jetted from the jet pipe (95) so as to draw a circular locus centering on the center of the soot container (7).
In order to generate a rotating water flow in the container (7) by jetting high-pressure water from the nozzle (93) to effectively stir the water, the nozzle (93) can be adjusted in height, and the nozzle (93 It is desirable to be able to adjust the inclination angle of the tip of the injection pipe (95).
The number of the injection pipes (95) of the nozzle (93) is not limited to two, and may be one or a plurality of three or more.

The operation of the food cleaning system described below is automatically performed by a preset program or the action of a detector provided at an appropriate place except for the manual operation of the operator.
However, the basket container support part (4) in the lowered position at the loading station S1 stands by with the presser frame (42) jumped up and the basket container support part (4) emptied.

  The operator places the flange (71) of the basket container (7) containing the cut vegetables on the receiving arm (41) of the basket container support section (4), and holds the presser frame (42) against the torsion spring (46). Then, the flange (71) of the container (7) is pressed down, and this state is locked by the locking means (5). The flange (71) of the dredge container (7) is sandwiched between the receiving arm (41) and the presser frame (42), and the dredge container (7) is being lifted or lowered during rotation. Can be reliably prevented from coming off the support portion (4) inadvertently.

Next, the elevating turntable (3) rises and rotates by one pitch (90 °) at the raised position, and the basket container (7) stops just above the water tank (6) of the washing station Sa.
The elevating turntable (3) is lowered and the dredger container (7) is immersed in the water tank (6) (see FIGS. 1 and 6).
At this time, the high-pressure water injection nozzle (93) is retracted from the upper side of the water tank (6) to the side, and does not obstruct the introduction of the dredger container (7) into the water tank (6).
When the nozzle (93) is switched to the operating position directly above the water tank, high-pressure water is injected from the injection pipe (95) of the nozzle (93), and a rotating water flow is generated in the dredger vessel (7). ) Is rotated by the reaction of high-pressure water injection.
As a result, the injection position of the high-pressure water with respect to the water surface continuously changes while drawing a circular locus, and the water surface and the cut vegetables of the straw container (7) are struck violently.

As shown in FIG. 12, if the injection pipe (95) is at a fixed position for rotation and the injection position of the high-pressure water is fixed, the water surface in the direction indicated by the arrow D at the high-pressure water injection position. A force F2 that is smaller than the force F1 but in the opposite direction to the force F1 is also applied to the force F1 that pushes. As a result, a phenomenon that the flow of the cut vegetables (100) stagnates upstream of the injection position of the high-pressure water occurs, and the cleaning action is halved. Moreover, the cut vegetables could not be stably rotated on the water stream due to differences in the type, size, amount, specific gravity, and the like of the cut vegetables.
In the present invention, as described above, the injection position of the high-pressure water with respect to the water surface continuously changes while drawing a circular locus. Therefore, regardless of the type of the cut vegetable, the flow of the cut food by the water flow is smooth, It is effective in shortening the cleaning time and eliminating washing spots.

Next, when the nozzle (93) returns again to the retracted position, the elevating turntable (3) rises and rotates one pitch at the raised position, the dredger container (7) is placed in the water tank (6) of the rinsing station Sb. Located on the top. As the elevating turntable (3) descends, the dredger container (7) is immersed in the water tank (6).
The nozzle (93) returns to the operating position, and the nozzle (93) also rotates in the water tank (6) while spraying high-pressure water to rotate the water in the container (7) and the cut vegetables. As a result, rinsing can be completed in a short time.
During the above washing and rinsing operations, the high pressure water sprayed from the nozzle (93) strikes the vegetables violently and cuts the top and bottom cut vegetables so that the top and bottom are replaced upside down. More effective in shortening the time.

The water overflowing from the jar container (7) escapes from the water-permeable cylindrical wall (45) of the presser frame (42) to the outside of the cylindrical wall (45). At this time, the cylindrical wall (45) serves as a filter, and cut vegetables can be prevented from escaping from the basket container (7).
Further, the gap formed between the side wall (70) of the basket container (7) and the annular wall (47) of the presser frame (42) is narrow, and cut vegetables pass through the gap and the flange (71) of the basket container (7). ), Even if the cut vegetables flow out of the gap, the flange (71) is held by the presser frame (42), and the cut vegetables go out of the basket container (7). Escape is effectively prevented.
The water overflowing from the water tank (6) flows into the overflow tank (63) and is discharged from the drain port (63c) to the water tank (64).

A lint filter (69a) is attached to the drain outlet (63c), and foreign matter such as cut vegetable scraps mixed in the drainage is captured by the lint filter (69a), so the foreign matter is the performance of the pump (65). Can be prevented, or the pump (65) can be damaged.
Furthermore, since an external clean water supply pipe (66) is opened in the vicinity of the water inlet of the pump (65), the water sprayed from the nozzle (93) to the water tank (6) is highly clean and washed. The effect can be enhanced.

Water that overflows from the water tank (6) is received in the overflow tank (63), further accumulated in the water storage tank (64), injected into the water tank (6) by the pump (65), and water is circulated for use. Can wash the cut vegetables.
Further, since the water tank (6) is slightly larger than the dredger container (7), there is little water remaining in the water tank (6) during the water circulation, and the external clean water and Since the water filtered by the lint filter (69a) is supplied to the water tank (6) and circulated, the cleaning effect of the cut vegetables can be enhanced also from this point.

Next, when the nozzle (93) is moved to the retracted position, the elevating turntable (3) is raised and rotated by one pitch at the raised position, the soot container (7) is located immediately above the discharge station S3.
When the elevating turntable (3) is lowered, the lever (52) of the locking means (5) hits the stopper (57a) of the unlocking means (56) immediately before the dredger container (7) is placed on the discharge conveyor (8), The lever (52) rotates against the lever torsion spring (58) in the direction opposite to the locking direction indicated by the arrow C in FIG. As a result, the lock claw (51) is detached from the receiving arm (41), and the lock of the presser frame (42) is automatically released.
When the lock on the presser frame (42) is released, the presser frame (42) jumps up in the direction of arrow B in FIG. 8 by the jumping torsion spring (46).

At the discharge station S3, the dredge container (7) is landed on the discharge conveyor (8) immediately before the receiving arm (41) of the dredge container support (4) reaches the descending end, so the dredge container (7) is the discharge conveyor. Immediately after landing on (8), the receiving arm (41) is released from the support. For this reason, the basket container (7) can be quickly and automatically escaped from the opening of the receiving arm (41) by being placed on the conveyor (8) substantially simultaneously with the landing on the discharge conveyor (8).
Next, when the elevating turntable (3) rises and rotates one pitch at the raised position, the empty container support (4) is positioned directly above the loading station S1. Due to the lowering of the lifting / lowering turntable (3), the empty container support (4) again stands by at the lowered position of the charging station S1.
The above operation is repeated each time the empty basket container support part (4) waits at the charging station S1, and the cut vegetables in the basket container can be efficiently washed.

  It should be noted that the time when the elevating turntable (3) is lowered, that is, the time when the straw container (7) is immersed in the water tank (6), or the straw container (7) in which the worker holds vegetables is put into the charging station. The maximum time that can be spent for setting on the support part (4) on S1 may be determined according to conditions such as the type of food to be cleaned and the amount of food contained in one basket container (7). About 1 to 5 minutes is appropriate.

  Even if the discharge conveyor (8) is omitted, since the discharge station S3 and the input station S1 are located next to each other, one worker can support the basket container (7) at the input station S1 (4 ) And taking out the soot container (7) from the discharge station S3.

  In the above embodiment, the tip of the injection pipe (95) of the nozzle (93) is inclined with respect to the water surface in the dredger container (7), so that the rotation means (97) of the nozzle (93) is obtained. (97) is not limited to this, a motor (not shown) is mounted on the arm tube (92), and the nozzle (93) can be rotated, such as rotating the nozzle (93) by the motor. Any configuration is possible.

  In the above embodiment, the nozzle (93) is retracted to the side, so that the container (7) can be put into the water tank (6) and taken out from the water tank (6). The nozzle (93) can be raised and retracted to a position higher than the height at which the dredger container (7) is put into the water tank (6) by making 67) a double slide tube or the like.

  Alternatively, if the height position of the nozzle (93) is maintained at a position higher than the height at which the dredger container (7) is put into the water tank (6) from the beginning, it is not necessary to retract the nozzle (93).

  Further, the number of stations on which the basket container (7) stops on the base (1) is not limited to four as described above, and can be implemented if it is three or more.

  The discharge conveyor (8) can be a roller conveyor.
