Soak and transfer devices having floating cleaning structure for plates}

The present invention relates to a food plate soaking transfer device having a floating cleaning structure. More specifically, it is disposed between the supply side where food plates requiring cleaning are recovered and the discharge side where the plate cleaning device is disposed, so that the recovered food plates stand upright. The present invention relates to a food plate soaking transfer device having a floating cleaning structure for soaking and cleaning food plates stored in the carrier while sequentially transferring the aligned carriers to the supply side and the discharge side.

In places where group meals are served, such as schools, public institutions, military bases, and rest areas, large quantities of tableware are used. These plates are put in a dishwasher and cleaned after the meal is served, removing any leftover food left on the dishes. It removes food waste, etc.

At this time, it is difficult to remove grains of rice or some leftover residue that are heavily stuck to the dishes, so residues remain even after going through the dishwasher.

Therefore, in the art, before putting dishes in a dishwasher, food residues are first removed through a pre-cleaning step, and then the dishes are put in the dishwasher to perform washing, rinsing, and drying processes.

This pre-cleaning involves placing a plate with food residue in a large bucket filled with detergent to soak the food residue, then holding the brush with one hand and the plate with the other hand and alternately wiping the top and bottom of the plate with the brush. This has been done by separating food residue from dishes.

However, although it is possible to pre-clean dozens of dishes with the above-mentioned method, when pre-cleaning more than a few hundred dishes, a lot of strain was placed on the shoulders and limbs of the cleaner due to the repeated washing operations, which eventually led to arthritis, etc. It may also cause muscle pain.

Meanwhile, in relation to the present invention, Korean Patent Registration No. 10-1612389 uses the cleaning liquid in the water tank as a medium to generate ultrasonic waves to provide microvibration, so that contaminants attached to dishes are removed through cavitation caused by microvibration. A tableware immersion cleaning device using ultrasonic waves is being proposed.

In addition, in Korean Patent Registration No. 10-1288221, in the air bubble dishwasher, the dishes are tilted from 65 degrees to 75 degrees in the longitudinal and inner direction on the upper dish inclination angle guide and the lower dish separation guide in the soaking tank. Automatic separation and continuous filling operations are carried out, detergent and hot water are placed in the soaking tank, and the air passing through the air bubble generator and air bubble pipe is released into the air by several air bubble generating nozzles installed at the bottom of the dish separation guide block. We are proposing an air bubble dishwasher prewasher that changes into a drop shape and circulates the washing water, and at this time, the soaking work and prewashing work of the dishes are automatically performed.

These pre-washing devices are preferable in terms of work efficiency because they pre-wash a large amount of dishes by putting them into a water tank and pre-cleaning them all at once.

However, it is difficult to reliably remove food residues stuck to the dishes using ultrasonic waves or air bubbles, and foreign substances remaining on the surface of the dishes are removed by simply oscillating ultrasonic waves or dispersing air bubbles in a single water tank. Preliminary washing of dishes is performed using washing water contaminated with a large amount of foreign substances, and foreign substances contained in the washing water may cause contamination of the dishes being prewashed.

Meanwhile, in Republic of Korea Patent Registration Publication No. 10-2391504, in promoting soaking and cleaning of dishes by immersing them in a long immersion cleaning tank in the longitudinal direction, the dishes are placed in an input space formed on one side of the immersion cleaning tank. A tableware immersion cleaning device is proposed that has a tableware transport structure that moves sequentially in the longitudinal direction and is sequentially transferred to and discharged into the discharge space, thereby facilitating immersion cleaning and transport of the dishes.

If the dishes are soaked and cleaned using this dishwashing device, it has the advantage of being able to simultaneously clean the dishes and move the dishes between sections.

However, in the conventional dish immersion washing device, when impregnating a dish tray with aligned dishes in soaking washing water, the operator must directly insert or discharge the dish tray into the soaking washing water, so the worker's body is directly exposed to the soaking washing water. occurs.

Accordingly, only low-temperature soaking and washing water that does not harm the worker's body can be used, which lowers the efficiency of soaking and washing, and also requires the worker to directly transport the dish tray, resulting in hard labor for the worker. The problem of unnecessary time being consumed is being pointed out.

It shows the detailed configuration of the unit, and Figures 3 and 4 are operation state diagrams showing the soaking and cleaning state of dishes stored in the carrier through the soaking transfer device for the plate proposed as a preferred embodiment of the present invention, and Figures 5 to 7 shows in detail the supply and discharge status of the carrier containing the dishes through the carrier elevating part in the soaking transfer device for food plates proposed as a preferred embodiment of the present invention, and Figure 8 is proposed as a preferred embodiment of the present invention. In the food plate soaking transfer device being used, the detailed configuration and operating state of the floating cleaning unit provided with a pressure pumping structure are shown. Figure 9 shows the carrier in the food plate soaking transportation device proposed as a preferred embodiment of the present invention. It shows the detailed configuration of and the state of compartmentally storing a unit number of food plates in the aligned storage space formed in the carrier.

The food plate soaking transfer device 1 proposed as a preferred embodiment of the present invention is between the supply side (IN), which collects and supplies used food plates (T), and the discharge side (OUT), where the dishwashing device is placed. It is a dedicated device for soaking and cleaning the food plates (110) recovered from the supply side (IN) by moving them to the discharge side (OUT) by impregnating them with soaking washing water.

The soaking transfer device 1 of the food plate is disposed between the supply side (IN) and the discharge side (OUT), as shown in FIGS. 1 to 4, and has a longitudinal immersion storage space ( An immersion transfer tank (10) having 11); It is disposed longitudinally at the bottom of the immersion storage space 11 of the immersion transfer tank 10 and includes a section transfer conveyor 20 that moves from the supply side (IN) to the discharge side (OUT).

The longitudinal immersion transfer tank 10 has a 3 m to 10 m long immersion storage space 11 in which a supply section 11A is formed on the supply side (IN) and a discharge section 11B is formed on the discharge side (OUT). It consists of a longitudinal enclosure.

In addition, the carrier 100 is composed of an open-top water permeable box with permeable openings 101 formed on the outer wall and bottom, and the soaking washing water stored in the immersion storage space 11 flows through the permeable openings 101. Then, the stored food plates 110 are soaked and cleaned.

At this time, as shown in Figures 1 and 9, the alignment space formed in the carrier 100 is partitioned left and right at set intervals by one or more partition bars 102, and the food plates 110 are placed on the partition bars 102. It is configured to be divided into units and stored separately in the sorting space partitioned by each unit.

In this embodiment, 20 food plates are arranged to stand in the partition alignment space divided by each partition bar 102, thereby preventing the phenomenon of the standing food plates being tilted to one side or the other and being fixed.

When configured in this way, the phenomenon of the food plates 110 being stuck in the alignment space while tilted to one side or the other is prevented, and as a result, the food plates 110 stored in partitions in the alignment space are used in the floating cleaning unit 30. Stable cleaning of foreign substances remaining on the surface can be achieved while flowing from side to side due to the flotation cleaning power, etc.

In addition, at the bottom of the immersion water storage space 11, a section transfer conveyor 20 with a plurality of transfer chains 23 attached between the drive shaft 21 and the driven shaft 22 is arranged in the longitudinal direction, and these transfer chains The carriers 100 supplied from the supply section 11A of the immersion water storage space 11 through (23) are sequentially transferred to the discharge section 11B, and are absorbed into the soaked washing water stored in the immersion water storage space 11. So that soaking cleaning is implemented.

At the bottom of the immersion transfer tank 10, soaking washing water containing food residues removed from the food plates 110 by soaking washing is collected, and food residues remaining in the collected soaking washing water are filtered through the filter net 12a. A suction cleaning port 12 for filtration and collection is formed, and the soaking cleaning water filtered through the suction cleaning port 12 is circulated and supplied to the immersion storage space 11 through a flotation cleaning portion 30, which will be described later.

In this embodiment, as shown in FIG. 4, one or more suction cleaning ports 12 are placed at the bottom of the immersion transfer tank 10, are stored in an upright position on the carrier 100, and are supplied through the section transfer conveyor 20. The food plates 110 that are transferred from the section 11A to the discharge section 11B are removed from the food plates 110 by the suction cleaning force provided through the suction cleaning port 12. ) to be suctioned and cleaned.

That is, it is stored upright in the carrier and undergoes first lifting and lowering cleaning and first floating cleaning in the supply section (11A) by the impregnation input carrier lifting part 40 and the floating cleaning part 30, and then is transferred to the section. It is moved to the discharge section (11B) in a state impregnated with soaked cleaning water through the conveyor (20), by the suction cleaning force provided through each suction cleaning port (12) disposed on the bottom of the immersion transfer tank (10). Be sure to clean by suction.

Meanwhile, in this embodiment, high-temperature (50°C to 90°C) soaking washing water is stored in the immersion storage space 11 of the immersion transfer tank 10, and is stored in an upright position in each carrier 100 to form a supply section. The food plates 110 moving from 11A to the discharge section 11B are subjected to high-temperature soaking cleaning using high-temperature soaking washing water to maximize soaking cleaning efficiency.

However, in the past, there was no dedicated structure provided for impregnating or ejecting the carrier 100 containing the food plates 110 into the immersion water storage space 11 where the soaking and washing water was stored, so field workers had to use the immersion water storage space 11. Hard labor is required to directly insert or remove the food plates 110 within (11).

In particular, when soaking washing water of high temperature (50°C to 90°C) is stored in the immersion water storage space 11 as in the present embodiment, the operator stores a plurality of food plates 110 in the immersion water storage space 11. (100) During the process of putting in or taking out, the stored high-temperature soaking washing water may come into contact with the worker's hands or other bodies, harming the safety of the worker, such as burns.

In order to overcome this problem, in this embodiment, the food plates 110 are connected to a supply side (IN) that supplies the food plates 110 requiring soaking and cleaning and a discharge side (OUT) that discharges the food plates 110 that have completed soaking and cleaning. ) are impregnated by supplying and arranging the carrier 100 to the supply section 11A of the immersion water storage space 11, or the impregnated carrier 100 is lifted out from the discharge section 11B of the immersion water storage space 11. Carrier elevating parts 40 and 50 are disposed, respectively.

With this configuration, the heavy carrier 100 can be safely and conveniently impregnated into or lifted out of the immersion reservoir space 11 while preventing physical contact with the high-temperature soaking water in the immersion reservoir space 11. .

To elaborate on this, in this embodiment, the supply side (IN) of the immersion transfer tank 10 is provided with a carrier 100 that accommodates the dishes 110 that require impregnation supply to the supply section 11A of the immersion storage space 11. A carrier elevating part 40 for impregnating input that is lowered and seated on the section transfer conveyor 20 is arranged.

And, on the discharge side (OUT) of the immersion transfer tank 10, the carrier 100, which has been impregnated in the immersion water storage space 11 and moved to the discharge section 11B, rises to place the carrier 100 in the water storage space. A carrier lifting part 50 for discharging the elevating unit discharged from (11) is disposed.

The carrier lifting units 40 and 50 proposed in the present invention include lifting frames 41 and 51, as shown in FIG. 2; A movable elevator body (42, 52) arranged in a lifting structure on the lifting frames (41, 51) and formed with shoulder arms (44) for supporting the carrier (100) in which the food plates (110) are stored and aligned; It includes lifting units (43, 53) that provide lifting force according to the lifting and lowering of the movable lifters (42, 52).

Preferably, a pair of shoulder arms 44, 54 are disposed symmetrically left and right on the movable lifters 42, 52 arranged in a lifting structure on the lifting frames 41, 51, and these shoulder arms 44, 54), both sides of the carrier 100 are held together to be raised.

Accordingly, the movable lifters (42, 52) are lowered into the storage space (11) to immerse the carrier (100) requiring supply while being lifted up and down at a set stroke distance by the lifting force provided through the lifting units (43, 53). The carrier 100 containing the food plates that have been impregnated, soaked, and cleaned is lifted out of the immersion water storage space 11 and lifted out from the immersion water storage space 11.

According to this embodiment, the lifting units 43 and 53, which lift and lower the movable lifters 42 and 52 at a set stroke distance, are a general-purpose cylinder and a rack that converts the rotational force of the drive motor into lifting force through a rack and pinion. It can be implemented in various forms such as and pinion forms, and all of these are scheduled to be within the scope of the present invention.

However, in this embodiment, drive motors 43a and 53a that generate rotational force; One end of the drive motor (43a, 53a) is fixed to the rotation axis, and the movable lift body (42, 52) connected to the eccentric link structure moves around the end by the rotation of the rotation axis along the lifting frame (41, 51). An eccentric link type lifting unit (43, 53) including eccentric link arms (43b, 53b) for lifting is proposed as a more preferable embodiment.

In order to achieve smoother lifting and lowering of the movable lifters 42 and 52, in this embodiment, interlocking slots 41a and 51a are formed in the movable lifters 42 and 52, and the interlocking slots 41a and 51a ), the turning ends of the eccentric link arms (43b, 53b) are assembled into a rolling link structure through rolling rollers, so that the rotational force of the driving motors (43a, 53a) is converted into lifting force and the movable lift body (42, 52) Ensure that the machine is lifted and lowered repeatedly at the set stroke distance.

Therefore, when the rotation axis of the drive motors 43a and 53a rotates in one direction, the eccentric link arms 43b and 53b arranged in an eccentric structure on the rotation axis of the drive motors 43a and 53a, as shown in FIGS. 4 to 7. ) rotates, and the movable lift body 42, 52 holding the carrier 100 is raised and lowered by the rotation of the eccentric link arms 43b and 53b.

At this time, in this embodiment, the carrier 100, which is raised and lowered by the carrier elevating parts 40 and 50, is installed on the bottom of the supply section 11A and the bottom of the discharge section 11B of the immersion storage space 11. An elastic elevation sphere (13) that elastically supports upward is placed.

According to the present embodiment, the elastic support force of the elastic lifter 13 is configured to be smaller than the weight of the carrier 100 in which the dishes are stored, so that it is held in the carrier 100 that is lowered by the carrier lifting parts 40 and 50. It is elastically compressed and naturally absorbs the downward shock of the carrier 100.

In addition, when the carrier 100 is raised by the carrier lifting units 40 and 50, the carrier 100 is elastically supported upward through elastic force due to compression, so that the carrier 100 in the soaked washing water rises. Suppresses the occurrence of overload of the lifting units (43, 53).

Therefore, when the operator on the supply side (IN) places the carrier 100 in which the food plates requiring soaking and cleaning are stored and aligned on the shoulder arms 44 and 54 of the raised movable lifters 42 and 52, the impregnation carrier The lifting unit 40 descends along the immersion water storage space 11 and seats the carrier 100 on the section transfer conveyor 20, and in this process, the carrier ( The dishes 110 stored and arranged in 100 are impregnated.

In particular, in the present invention, the soaked washing water is discharged upward to the carrier 100, which is repeatedly impregnated, supplied and lifted by the carrier elevating parts 40 and 50, so that the food plates 110 stored in the carrier 100 It further includes a flotation cleaning unit 30 that provides a flotation force including a vertical flotation force and a water force.

The floating cleaning unit 30 is located in the supply section 11A of the immersion storage space 11 where the carrier 100 containing the food plates 110 is impregnated, supplied, and lifted out by the carrier elevating units 40 and 50. At the bottom of and the bottom of the discharge section 11B, the soaked washing water is discharged upward from the bottom of the sections 11A and 11B through the circulating water pump 31.

More specifically, as shown in Figures 1 and 4 to 8, the flotation cleaning unit 30 includes a distribution chamber 32; A circulation water pump (31) disposed between the immersion water storage space (11) and the distribution chamber (32) to circulately supply soaked washing water stored in the immersion water storage space (11) to the distribution chamber (32); And it is formed in communication with the distribution chamber 32, and the soaked washing water supplied to the distribution chamber 32 is distributed to the bottom of the supply section 11A where the carrier elevating parts 40 and 50 are arranged, or to the discharge section 11B. A plurality of sprays are ejected upward from the bottom of the carrier 110, which is raised and lowered by the carrier elevating units 40 and 50, and provide levitation cleaning power to the carrier 100 and the food plates 110 stored in the carrier 100. Contains a levitation tube (33).

In addition, as shown in FIG. 7, one or more spiral guide pieces (33a) are disposed in the floating washing pipe (33), and the soaking washing water ejected through the floating washing pipe (33) is directed to the spiral guiding piece (33a). It interferes with the spiral structure and turns into a spiral structure and is ejected upward into the immersion storage space (11).

Therefore, when the distribution chamber 32 is filled with the soaking washing water stored in the immersion storage space 11 through the circulation water pump 31, the soaking washing water filled in the distribution chamber 32 is supplied to the supply section 11A. ) and is ejected upward to the supply section (11A) and the discharge section (11B) through the floating cleaning pipes (33) disposed at the bottom of the discharge section (11B).

In Figure 8, which shows another embodiment, a compression pumping block 34 is pressurized by a carrier 100 descending into the distribution chamber 32 and enters the distribution chamber 32 to increase the internal pressure of the distribution chamber 32. By arranging, the compression pumping block 34 enters the distribution chamber 32 by the carrier 100 descending by the carrier elevating units 40 and 50, thereby increasing the internal pressure of the distribution chamber 32 to form a floating washing pipe. The soaked washing water filled in the distribution chamber 32 is discharged at a higher pressure through (33). With this configuration, even if the capacity of the circulating water pump 31 is small, the soaking washing water can be ejected upward at a higher pressure.

At this time, the compression pumping block 34 is pushed upward by the elastic lifting port 13 and is configured to advance upward from the distribution chamber 32 unless pressurized by the carrier 100 is applied.

Therefore, the carrier 100, which stores the food plates 110 in an upright position and repeatedly raises and lowers them in the supply section 11A and the discharge section 11B by the carrier elevating units 40 and 50, has a floating cleaning tube ( 33) The flotation cleaning power is provided by the soaking cleaning water that is jetted upward through the holes.

That is, as shown in FIG. 5b, the food plates 110 stored in an upright position on the carrier 100 experience friction with the soaking washing water ejected upward by the floating washing pipes 33 during the raising and lowering process of the carrier 100. Washing is performed by, and in particular, in the lowering process, as shown in FIGS. 5b and 7a, stronger friction occurs with the soaking washing water ejected upward, resulting in more stable washing of foreign substances remaining on the surface of the food plate 110.

In addition, in the process of raising the carrier 100, as shown in FIGS. 5A and 7B, not only the washing by the upwardly sprayed soaking water but also the vertical lifting force is assisted, making it possible to raise the carrier 100 with a small amount of force. And, as a result, the carrier lifting units 40 and 50 are capable of lifting the carrier 100 accommodating the food plates 110 upright without generating excessive load.

In addition, in this embodiment, a transport conveyor 60 is disposed to transport the empty carriers 100 collected from the discharge side OUT to the supply side IN, thereby improving the convenience of transporting the empty carriers 100. Ensure that it is secured.

To describe this in detail, in this embodiment, the transfer conveyor 60 that transfers the section from the discharge side (OUT) to the supply side (IN) is placed on the upper part of the immersion transfer tank 100 to be spaced apart vertically.

The conveyor 60 is attached to the drive shaft 61 and the driven shaft 62 and between these drive shafts and the driven shaft as shown in FIG. 4, and is transferred from the discharge side (OUT) to the supply side (IN) by driving the drive shaft. A conveyor structure including a conveyance belt 63; The conveyor structure is supported to be spaced apart from the upper part of the immersion transfer tank 10, and the immersion storage space is provided through the carrier elevation parts 40 and 50 between the vertically spaced immersion transfer tank 10 and the return conveyor 60. It includes a support body 64 that forms a carrier ingress and egress space 65, which is an ingress and egress path for the dish trays 100 supplied to or discharged from (11).

In configuring the transfer conveyor 60 to be placed on the upper part of the immersion transfer tank 10 as in the present embodiment to transfer the empty carrier 100, there is at least a portion of the carrier between the transfer conveyor 60 and the immersion transfer tank. If an entry and exit space higher than the height is secured, the worker's hard labor can be eliminated by directly transporting the empty carrier 100 with the dishes taken out from the discharge side (OUT) to the supply side (IN) located on the opposite side. It also has the unique feature of enabling stable supply and discharge of the carrier 100 through the carrier elevating units 40 and 50.

In the following, the process of soaking and transferring food plates through the soaking and transferring device according to this embodiment will be described in detail.

The food plates recovered from the initial supply side are aligned and stored in the carrier in an upright manner, and the carrier is supplied to the impregnating carrier elevating unit 40 disposed on the supply side (plate alignment supply process).

Afterwards, the impregnation input carrier lifting unit 40 repeatedly moves up and down along the supply section of the immersion water storage space to repeatedly inject and extract the soaking washing water stored in the immersion water storage space. (First lifting and lowering cleaning) process)

In this way, the food plates 110 arranged on the carrier 100 are lowered, entered, and lifted into the soaking washing water stored in the immersion storage space 11 in the process of being repeatedly raised and lowered by the impregnation input carrier elevating part 40. As it is taken out, preliminary cleaning is performed by friction with the soaking washing water stored in the immersion storage space 11.

In this process, the carrier 100, which is lifted up and down in the supply section (11A) by the impregnation input carrier elevating part 40, has a vertical flotation force and water force due to a flotation water force provided through the flotation cleaning part 30. The force is provided to minimize the load on the impregnation carrier elevating part 40, and the foreign substances remaining on the surface of the food plate 110 are stably washed away by strong friction with the soaking washing water sprayed upward. (1) Tea flotation and washing process)

The impregnating carrier lifting unit 40 disposed on the supply side (IN) implements a lifting and lowering cleaning process in which the carrier 100 is repeatedly raised and lowered in the supply section 11A several times, and then is finally lowered to lower the carrier 100. Ensure that it is seated on the section transfer conveyor 20 (carrier impregnation input process).

Thereafter, the carrier 100 impregnated and introduced into the section transfer conveyor 20 in the supply section 11A is supplied along the immersion water storage space 11 in which high-temperature soaking cleaning water is stored by the section transfer conveyor 20. ) to the discharge section 11B, and during this process, the food plates 110 stored in the carrier 100 are cleaned by high-temperature soaking with high-temperature soaking washing water (high-temperature soaking and section transfer process).

In this high-temperature soaking and section transfer process, the suction cleaning port (12) sucks the soaking cleaning water stored in the soaking water storage space (11) into the suction cleaning port (12) by the suction force provided through the circulating water pump (31). do.

The food plate 110 is stored in an upright position in the carrier 100 by the suction cleaning force provided by the suction and is moved sectionally to the discharge section 11B through the suction cleaning port 12 through the section transfer conveyor 20. The remaining foreign matter is removed by suction into the suction cleaning port 12 formed at the bottom (suction cleaning process).

The carrier 100, which has been moved to the discharge section 11B by the section transfer conveyor 20, rises along the discharge section 11B of the immersion water storage space 11 by the carrier lifting unit 50 for lifting. Next, the descending process is repeated several times, and the descending inflow and upward extraction are repeated into the soaking washing water stored in the immersion storage space (11) (second lifting and lowering washing process).

In this process, the carrier 100, which is raised and lowered in the discharge section (11B) by the lifting carrier elevating section 50 for elevating the extraction, causes the soaked washing water to be ejected upward into the discharge section (11B) through the floating cleaning section 30. Vertical lifting force and water force are provided from the carrier 100 to minimize the load on the lifting and ejecting carrier lifting unit 50 due to the lifting of the carrier 100, and the food plate 110 is removed by strong friction with the soaking washing water sprayed upward. ) Stable washing of foreign substances remaining on the surface is achieved (second flotation washing process).

The carrier lifting unit 50 for elevating the discharge disposed on the discharge side (IN) implements a secondary lifting and lowering cleaning process in which the carrier 100 is repeatedly raised and lowered several times in the discharge section (11B), and then the discharge section (11B) Finally, the carrier 100 is lifted out (carrier lifted out process).

Afterwards, the worker takes out the soaked and cleaned dishes 110 one by one from the carrier 100 that has been lifted out of the immersion storage space 11 by the lifting unit 50 and places the dishes on one side. They are sequentially supplied to the cleaning device, and the empty carriers 100 from which the food plates 110 have been removed are put into the return conveyor 60, and the empty carriers are sent to the supply side (IN) where the food plates 100 requiring immersion cleaning are recovered. 100) is returned.
