  The present invention relates to a container dewatering device including a container table for dewatering a cleaned container.

  For example, when a large amount of items such as bread and side dishes are delivered to a store such as a convenience store or a supermarket, a container that can accommodate a large number of these items is used. This type of container is called, for example, a plastic tray, pallet, container or the like. After the articles are brought in, the containers are collected from each store and transported to a predetermined washing place by a truck or the like in a stacked state. The transported containers in the stack are cleaned using a cleaning device for repeated use.

  The washed container is dehydrated by being held by a dehydrating apparatus described in Patent Document 1 and rotating to drain water. The dehydrator includes a rotating disk and a plurality of container holding pins. The rotating disk is provided with a plurality of container holding pins in parallel downward.

  When the container is actually washed, the conveyor conveys the inside of the container downward (backward) to a position below the rotating disk. The transported container raises the table upward, places the upper surface of the table against the inner bottom surface of the container and lifts the container, thereby positioning the container on the transport conveyor between the plurality of container holding pins. Accordingly, the plurality of container holding pins rotate the container together with the rotation of the rotating disk in a state where the container is held.

  In this way, the container table 20 is lifted in the Z1 direction, so that the container M to be dehydrated on the conveyor belts 7 and 7 is floated by the container table 20 and placed on the container table 20. 20 is lifted to the dehydrator 4 in the Z1 direction.

  Accordingly, as shown in FIGS. 2 and 3, the container table 20 is configured such that the corner portions at the four corners of the container M are rotated by using the support members 51H to 58H and the support members 61H to 64H of the dehydrator 4. It can be positioned and held detachably within.

  At this time, the lifting rod 22 of the drive device 21 remains elevated in the Z1 direction according to a command from the control unit 100. As shown in FIGS. 2 and 8, the container table 20 holds the container M to be dehydrated. Holding from below.

  Next, when the drive motor 31 is continuously rotated according to a command from the control unit 100, the rotating body 30 is continuously rotated. As a result, the container M to be dehydrated in one or more stages is continuously rotated in the V direction while being held by the rotating body 30, so that water adhering to each container M is drained by centrifugal force. Can be dehydrated.

  When the container M is dehydrated by the continuous rotation of the rotating body 30 of the dehydrator 4 shown in FIG. 2, the support members 51H to 58H of the spread prevention ring 70 are the tip portions (lower end portions) of the container guide rods 51 to 58, respectively. ) 59 side, and the support members 61H to 64H are held on the tip (lower end) 69 side of the container guide rods 61 to 64, respectively.

  For this reason, even if the length L of the support members 51H to 58H and the support members 61H to 64H is long, the spread prevention ring 70 is connected to the tip end (lower end) 59 side of the container guide rods 51 to 58 and the support members 61H to 64H. The front end portion (lower end portion) 69 side can maintain the shape and can be prevented from spreading outward due to centrifugal force.

  As described above, since the support members 51H to 58H and the support members 61H to 64H of the spread prevention ring 70 suppress the force spreading due to the centrifugal force and do not spread outward, the container M does not jump out of the rotating body 30. . The support members 51H to 58H and the support members 61H to 64H do not spread and bend even after a long period of time. Thereby, it can prevent that the container M remove | deviates from the rotary body 30 by centrifugal force. In this manner, when the container M is dehydrated, the spread prevention ring 70 prevents the support members 51H to 58H and the support members 61H to 64H from spreading outward, so that the dehydration process of the container M can be performed stably and the container The safety at the time of use of the dehydrating apparatus 1 for a container having a table is improved.

  In the container dehydrating apparatus 1 including a container table, the container table 20 includes a main body portion 80, a plate-like first table member 81, and a plate-like second table member 82. Structure. For this reason, even when the container table 20 is present when the container M is dehydrated, the discharge of moisture removed from the container M is not hindered by the presence of the container table 20.

  Next, when the control unit 100 shown in FIG. 2 stops the operation of the drive motor 31 and the dehydration of each container M is completed, the lifting rod 22 of the drive device 21 contracts in the Z2 direction according to a command from the control unit 100. Then, the dehydrated container M together with the container table 20 is lowered in the Z2 direction. As a result, the container table 20 is lowered below the conveyor belts 7 and 7, so that the dehydrated containers M can be transferred from the container table 20 onto the conveyor belts 7 and 7 and returned.

  After the container M is dehydrated, when the transport belts 7 and 7 pay out the containers M from the stop position P along the transport direction X, the stopper 12 is lowered from the upper surface of the transport belts 7 and 7. Yes. Thereby, the container M to be dewatered by the conveyor belts 7 and 7 can be dispensed along the conveyance direction X.

  FIG. 12 shows a state in which the container table 20 is supported by the container table 20 in the embodiment of the present invention. On the other hand, FIG. 13 shows a state in which the table 110 supports the container M arranged face down in the conventional comparative example.

  Thereby, the container table 20 can hold | maintain the container M, without touching the inner bottom face D of the container M at all, can be lifted in the Z1 direction, or can be lowered in the Z2 direction. Therefore, there is no contact in the inner bottom surface D with which food or the like comes into contact, and the inner bottom surface D is not damaged when being lifted and lowered. For this reason, the container M after washing | cleaning and spin-dry | dehydrating eliminates the problem of hygiene.

  On the other hand, in the conventional comparative example shown in FIG. 13, the upper surface of the table 110 is directly applied to the inner bottom surface D of the container M to lift the container M. And after washing | cleaning, the container M is lowered | hung in the state which contacted the upper surface of the table 110 with the inner bottom face D of the container M again. Since the table 110 directly hits the inner bottom surface D of the container M that has been touched by the container such as food, there is a possibility that dirt will adhere from the table 110.

  Further, since the table 110 rotates together with the container M, the rotation of the container M itself stops simultaneously with the stop of the rotation of the table 110 when the dehydration of the container is completed, but the table 110 itself is not controlled to be stopped. It itself continues to rotate due to inertial force. For this reason, the inner bottom surface D of the container M and the upper surface of the table 110 are rubbed, and the inner bottom surface D of the container M may be scratched, and dirt may accumulate on the scratch.

  As described above, the container dehydrating apparatus 1 including the container table according to the embodiment of the present invention is a dehydrating apparatus for the container M that rotates and dehydrates the container M, and holds and rotates the container M to rotate the container.

A container elevating unit 3.

  As a result, the container table 20 is held in a state of receiving the edge portion MR of the container M, so that the container table 20 holds and lifts or lowers the container M without touching the inner bottom surface D of the container M. Can do. Therefore, there is no contact in the inner bottom surface with which food or the like comes into contact, and the inner bottom surface is not damaged when being lifted or lowered. For this reason, dirt is prevented from adhering to the inner bottom surface D of the cleaned container M, and the inner surface D of the container M is not damaged, and the cleaned container M is dehydrated to remove the container M. Can be kept hygienic.

  The container table 20 includes a main body portion, a plate-like first table member that receives an edge portion of the container M fixed to the main body portion, and a plate fixed to the main body portion so as to be parallel to the first table portion. A second table member having a shape. Thereby, it is a simple structure with a clearance gap which has a main-body part, a plate-shaped 1st table member, and a plate-shaped 2nd table member, and even if the container table 20 exists at the time of dehydration of the container M, a container The discharge of moisture removed from M is not disturbed by the presence of the container table 20.

  The dehydrating device 1 of the container M has a transport device that transports the container M to be dehydrated at a corresponding position of the dehydrator 4, and the transport device is a container to be dehydrated at a corresponding position of the dehydrator 4. When M is transported, the container table 20 supports the container M in a state where the container M on the transport device is raised to the dehydrator 4 side and is held by the dehydrator 4, and the container table 20 supports the container M. The container table 20 can be rotated together with the dehydrator 4, and when the dehydration of the container M is completed, the container table 20 moves down together with the container M and returns the container M to the transport device.
