The washing water having a predetermined temperature is sent to the washing nozzle section 211 at a high pressure via the second washing water pipe 219 by the washing water pump 215 and is again sprayed from the washing nozzle section 211 to the container 1. Thus, in the cleaning region 21, the cleaning water can be circulated and reused.

  In the washing region 21, the washing water is a washing for an alkaline washing machine that has a predetermined detergent, for example, sodium hydroxide, potassium hydroxide or the like as a main raw material, and has a pH of about 10 to 12 when mixed with the predetermined water. Produced by mixing agents. In addition, what is necessary is just to adjust the kind, density | concentration, etc. of the detergent mixed in wash water according to the grade of the stain | pollution | contamination of the container 1. FIG. Moreover, it is not necessary to mix detergent in the washing water depending on the degree of contamination of the container 1.

  In this embodiment, a lower tank 212 is provided below the cleaning zone 2, and the cleaning water stored in the lower tank 212 is sent to the intermediate tank 213 by the submersible pump 214. At this time, by making the volume of the intermediate tank 213 larger than the volume of the lower tank 212, more washing water can be stored in the intermediate tank 213 than in the lower tank 212. As a result, even if the amount of the cleaning water stored in the lower tank 212 is small, the depth of the lower tank 212 can be reduced without causing an obstacle to the circulation of the cleaning water. As a result, the depth of the pit S that accommodates the lower tank 212 can be reduced.

  It is possible to omit the intermediate tank 213 and the cleaning water pump 215 by adjusting the amount of cleaning water flowing to the lower tank 212 and the amount of cleaning water discharged by the submersible pump 214. In this case, instead of the heating means for heating the wash water stored in the intermediate tank 213, the lower tank 212 is provided with a heating means, or by supplying heated wash water directly from an external hot water supply facility, The tank 213 and the cleaning pump 215 can be omitted. By doing so, the amount of washing water used in the container washing / dropping dryer W can be reduced. In that case, the cleaning water stored in the lower tank 212 is jetted from the cleaning nozzle unit 211 by the submersible pump 214.

  The predetermined detergent to be mixed with the washing water is supplied by a detergent supply machine (not shown) provided in the intermediate tank 213. A detergent concentration detection sensor (not shown) installed in the intermediate tank 213 detects the detergent concentration of the wash water stored in the intermediate tank 213, and sends the detected signal to the detergent supplier. Based on the detected signal, the detergent supply machine supplies the detergent so that the washing water has a predetermined concentration.

  The rinsing region 22 includes a rinsing nozzle portion 222 that ejects finishing water. In the rinsing region 22, the cleaning water adhering to the container 1 in the cleaning region 21 is washed away by rinsing the container 1 with finish water. The rinsing region 22 includes a flat water plate 221 that is inclined downward to the lower tank 212 of the downstream cleaning region 21 of the two cleaning regions 21. Then, the finishing water sprayed from the rinsing nozzle portion 222 to the container 1 flows down to the lower tank 212 of the cleaning region 21 on the downstream side through the water flow plate 221.

  As the finishing water, for example, tap water is used. The finishing water is supplied from the finishing water pipe 224 and flows to the rinsing nozzle portion 222 via the mixing valve 225. In the mixing valve 225, the high temperature steam supplied from the boiler 216 via the steam pipe 217 is mixed with the finish water, thereby heating the finish water to a predetermined temperature, for example, about 80 degrees C.

  As shown in FIG. 3, the container cleaning / deleting / drying machine W includes a droplet removal / drying zone 3 continuous from the cleaning zone 2. The droplet removal and drying zone 3 ejects air from the plurality of droplet removal and drying means 301 to 310 and removes moisture adhering to the container 1 (washing water and / or finishing water adhering to the container 1 in the washing zone 2). dry. In the drop removal drying zone 3, the water adhering to the container 1 is removed by the wind pressure of the air sprayed from the drop removal drying means 301 to 310. Moreover, since some of the air injected from the droplet removal drying means 301 to 310 is heated to a predetermined temperature by the heat exchangers 501 to 503, it adheres to the container 1 by being injected to the container 1. The water is evaporated by heat and dried.

  As shown in FIGS. 3 and 5, in the drop removal drying zone 3, blowers 401 to 407 and heat exchangers 501 to 503 are provided on the ceiling of the container cleaning drop removal dryer W. The blowers 401 to 407 are connected to the drop removal drying means 301 to 310 and eject air from the drop removal drying means 301 to 310. The blowers 401 and 402 are connected to the heat exchanger 501, the blowers 403 and 404 are connected to the heat exchanger 502, and the blowers 405 and 406 are connected to the heat exchanger 503.

  Since the blowers 401 to 406 are connected to the heat exchangers 501 to 503, the droplet removal drying means 301 to 308 connected to the blowers 401 to 406 inject the air heated by the heat exchangers 501 to 503. Further, since the blower 407 is not connected to the heat exchanger, the droplet removal drying means 309 and 310 connected to the blower 407 have a lower temperature than the heated air sprayed from the other droplet removal drying means 301 to 308. Jet of air.

  Part of the air jetted from each of the droplet removal drying means 301 to 310 toward the container 1 is sucked into the blowers 401 to 407 through the openings provided in the ceiling of the container cleaning droplet removal dryer W, and again. It will discharge to the container 1 (refer arrow b of FIG. 5). Therefore, air will circulate.

  In the container washing / dropping / drying machine W, each of the blowers 401 to 406 sucks air of each of the drying areas 30 to 33 (see FIG. 15) through an opening in the ceiling, and heats the air to a predetermined temperature, for example, 80 degrees C. It injects toward the container 1. A part of the air having a predetermined temperature injected into the container 1 is again sucked from the opening provided in the ceiling by the blowers 401 to 406 and heated to the predetermined temperature again by the heat exchangers 501 to 503. Is injected into. That is, since the air heated to a predetermined temperature is circulated and used, the amount of heat for heating the air again to the predetermined temperature can be reduced, and energy can be saved.

Note that the upper part 101, the middle part 102, and the lower part 103 merely refer to the order of the positions of the containers 1 in the vertical direction. That is, a position below the upper part 101 is a middle part 102, and a position below the middle part 102 is a lower part 103. Therefore, for example, from the ceiling portion 11 to the lower shelf 19 is the upper portion 101 of the container, from the lower shelf 19 to the upper surface of the bottom portion 12 is the middle portion 102 of the container, and from the upper surface of the bottom portion 12 to the ground contact point of the wheel 122 May be the lower part 103 of the container.

  Further, the left-right direction on the drawing in FIG. 6A is also referred to as the front-rear direction of the container 1, and the left-right direction on the drawing in FIG. In addition, the side surface portion 15 on the container 1 conveyance direction side is also referred to as the front side surface portion 15, and the side surface portion 15 opposite to the container 1 conveyance direction side is also referred to as the rear side surface portion 15.

  As shown in FIG. 6A, when the container 1 is cleaned, the hinge doors 16 are kept 180 degrees open by a fixing jig (not shown), and the container 1 is moved from the side portion 15 on the front side. The container 1 is carried into the container cleaning / dropping dryer W. Accordingly, the container 1 is transported from the front in the transport direction in the container cleaning / dropping / drying machine W in the order of the front door portion 161, the storage portion 17, and the rear door portion 162 of the container 1.

  The lower surface of the rectangle that forms the bottom surface of the bottom 12 of the container 1 has casters 121 that support the wheels 122 so that they can roll by metal fittings (not shown) at the four corners. The four casters 121 can rotate the wheels 122 360 degrees around the vertical direction, and roll the wheels 122 of the casters 121 so that the container 1 can move freely in the front-rear and left-right directions.

  As shown in FIG. 6B, the container 1 has a horizontally elongated recess 151 in both side surface portions 15, and a horizontally long handle 152 is provided in the recess 151. For example, in a facility that uses a large amount of tableware such as a school lunch center C for school lunch, the worker moves the container 1 while holding the handle 152 when storing and carrying the tableware. Can do.

  As shown in FIGS. 6 (A) and 6 (B), the container 1 is a bar whose both ends are supported by a pair of support portions 123 provided on the front portion 13 side and the back portion 14 side on the bottom portion 12 thereof. 124 is provided. The bar 124 is a rod-like member extending in a straight line with a cross section of a perfect circle, and both ends are formed by attaching disk-like members having an enlarged diameter. For example, a bar 124 can be formed by welding and fixing a stainless steel disc-shaped member having a diameter of 40 mm to both ends of a stainless steel rod-like member extending linearly in a cross section of a perfect circle having a diameter of 27 mm. . The bar 124 may be a rod-shaped member having a hollow cross section.

  A pair of support portions 123 are attached so that a bar 124 is provided at a substantially center in the front-rear direction of the bottom portion 12 of the container 1. The pair of support parts 123 support the bar 124 so that it can move up and down and roll while the bar 124 is inserted into the long hole 125 of the support part 123.

  Specifically, the support 123 and the bar 124 will be described. The width of the long hole 125 of the support 123 is slightly wider than the circular diameter that is the cross-sectional shape of the bar-shaped member of the bar 124. Therefore, the bar 124 inserted into the long hole 125 can move up and down by a predetermined dimension, for example, about 70 mm while being inserted into the long hole 125, and the bar 124 rolls in the circumferential direction of the cross-sectional shape. It is possible. Further, the disk-shaped members at both ends of the bar 124 have a diameter larger than the width of the long hole 125 of the support part, and the bar 124 is prevented from falling off from the pair of support parts 123.

  As shown in FIGS. 7 and 8, the container 1 is configured so that the cleaning water is less likely to accumulate and can be easily removed. Specifically, the upper shelf 18 and the lower shelf 19 of the container 1 are formed of cylindrical pipes.

  The upper shelf 18 and the lower shelf 19 of the container 1 are joined so as to be sandwiched between a pair of long pipes 182 from both ends of the short pipes 181 arranged in parallel at substantially equal intervals. Both ends of the short pipe 181 are joined to the side surface which is the inside of the long pipe 182 by welding. The cylindrical pipe is easy to flow down even if moisture is attached, and it is easy to remove the moisture attached to the container 1.

  Moreover, as shown in FIG. 7, the edge part 126 of the member which forms the bottom part 12 of the container 1 is return | folded below. The lower end of the end portion 126 faces downward so that moisture attached to the container 1 can easily flow down. In addition, holes (not shown) are formed in the lower surface of the short pipe 181 and the long pipe 182 so that moisture that has entered the short pipe 181 and the long pipe 182 is easily discharged. A discharge hole penetrating the bottom portion 12 may be provided on the upper surface of the bottom portion 12. In that case, moisture accumulated on the upper surface of the bottom portion 12 can be discharged to the outside.

  In this embodiment, the container 1 is formed by bending and welding a sheet metal, for example, a stainless steel plate having excellent corrosion resistance. Moreover, the substantially rectangular parallelepiped storage portion 17 is configured to be divided into three stages by an upper shelf 18 and a lower shelf 19. However, the container 1 may have other shapes as long as it has casters 121 and bars 124 at the bottom. For example, a caster 121 may be provided in the lower part of the bowl whose upper surface is open, and a cooking utensil may be placed in the bowl and carried into the container washing / dropping dryer W. The shape of the container 1 can be changed to various shapes.

(Transport mechanism)
As shown in FIGS. 9 to 12, the transport mechanism 7 transports the container 1 through a straight path formed substantially horizontally in a straight line without forming a path that curves in a top view.

  As shown in FIG. 9, the transport mechanism 7 includes a pair of top chains (transport means) 71 for transporting the container 1 and a transport rail 72 that guides the wheels 122 of the container 1. The top chain 71 mounts and conveys the bar 124 of the container 1. The top chain 71 and the transport rail 72 extend linearly in parallel.

  As shown in FIGS. 11A and 11B, the top chain 71 has a plate attached to the upper part of the chain and is configured endlessly as a transport chain. The top chain 71 is folded back by a drive sprocket 74 and a driven sprocket 77, and has a feed side that drives in the conveying direction of the container 1 and a return side that drives in a direction opposite to the feed side. The upper surface on the feed side of the top chain 71 serves as a conveying surface 76 on which the bar 124 of the container 1 is placed.

  Moreover, as shown in FIG. 9, the top chain 71 is attached with engaging claws (engaging portions) 73 for engaging with the bars 124 of the container 1 at equal intervals in the transport direction. In the present embodiment, for example, the engaging claws 73 are formed at a predetermined pitch, for example, a pitch of 2 m, and the container 1 is conveyed at the predetermined pitch. The engaging claw 73 is manufactured by cutting stainless steel, for example.

  The transport mechanism 7 includes, as a driving source, an electric motor (not shown) housed in the housing box L on the side near the carry-out port 5. The electric motor is connected to an inverter (not shown), and the rotation speed and the like can be changed. The electric motor drives the top chain 71 by rotating a drive sprocket 74 (see FIGS. 5 and 11).

  A sensor (not shown) for detecting that the engagement claw 73 has passed a predetermined position is provided near the drive sprocket 74 on the return side of the top chain 71. Further, the control panel G includes an inverter, and the rotation speed of the electric motor is changed by the inverter.

  The sensor detects the engaging claw 73 that has passed a predetermined position, sends a signal to the control panel G, receives the signal, and changes the rotation speed of the electric motor by the inverter.

  The top chain 71 is based on low-speed driving, and therefore the electric motor is normally driven at low speed. The engaging claw 73 provided on the conveying surface 76 of the top chain 71 that is driven at low speed engages with the bar 124 of the container 1 to move the container 1 at a predetermined speed, for example, at a speed of 1.5 m / min.

  When the engaging claw 73 provided on the conveying surface 76 of the top chain 71 that is driven at a low speed passes a predetermined position, the sensor detects the engaging claw 73 and sends a signal to the control panel G. Upon receiving the signal, the control panel G causes the inverter to drive the electric motor at a high speed for a predetermined time, for example, 20 seconds, to drive the top chain 71 at a high speed, and to move the container 1 in which the bar 124 is engaged with the engagement claw 73 for a predetermined time. Move at a high speed, for example, 3 m / min.

  After a predetermined time has elapsed, the top chain 71 returns to low speed driving. Then, the container 1 is moved at a low speed for a predetermined time until the next engagement claw 73 passes a predetermined position, for example, for 40 seconds.

  Thus, while each engaging claw 73 provided on the top chain 71 moves by one pitch, the top chain 71 repeats high speed driving and low speed driving for a predetermined time, respectively, and the container 1 similarly Switching is possible so as to repeat high-speed movement and low-speed movement for a predetermined time. That is, the container 1 is moved at a high speed and a low speed while the container 1 travels a predetermined interval at which the engaging claws 73 are provided, for example, 2 m.

  The transport rail 72 includes a concavo-convex portion (deceleration means) 720 including a plurality of convex portions provided on the transport rail 72 on the carry-out port 5 side of the droplet removal drying zone 3. When the container 1 self-propels on the conveyance rail 72, the container 1 can obtain a deceleration effect by the wheels 122 of the container 1 getting over the uneven portion 720. That is, the concavo-convex portion 720 acts as a speed reduction unit.

  In addition, although the uneven | corrugated | grooved part 720 is comprised by providing a convex part in the conveyance rail 72, you may comprise the uneven | corrugated | grooved part 720 by providing a recessed part in the conveyance rail 72. FIG.

  As shown in FIGS. 10 and 11, in the transport mechanism 7, a pair of transport rails 72 are disposed outside in the left-right direction orthogonal to the transport direction and a pair of top chains 71 are disposed inside the utility space 70 in the center. Form.

  The feed side and the return side of the top chain 71 are arranged to be higher than the floor surface FL. In the present embodiment, the engaging claw 73 on the return side of the top chain 71 has a vertex that is substantially the same height as the floor surface FL. Therefore, in the present embodiment, the entire top chain 71 is disposed so as to be above the floor surface FL. The utility space 70 can be used as a scaffold for performing cleaning and maintenance in the container cleaning / dropping dryer W.

  Further, the transport rail 72 is provided at a height substantially equal to the floor surface FL. The height of the conveying surface 76 is, for example, 126 mm from the floor surface FL, and the height of the engaging claw 73 is, for example, 30 mm from the conveying surface 76. Therefore, the height from the floor surface FL to the top of the engaging claw 73 is 156 mm.

  In the present embodiment, the pair of transport rails 72 are provided at the same height position from the floor surface FL, but one height position of the pair of transport rails may be changed. In that case, the container 1 can be transported so as to be inclined in the left-right direction, and when the container 1 described later is subjected to droplet removal drying, the moisture adhering to the container 1 is inclined and moved toward the lower side. Thus, moisture can be removed more easily.

  As shown in FIG. 11A, the pair of top chains 71 are each provided with a pair of engaging claws 73 spaced in the left-right direction orthogonal to the transport direction. Each engagement claw 73 moves in the transport direction (see arrow c in FIG. 11) as the drive sprocket 74 of the top chain 71 rotates. In both the top chains 71, the engaging claws 73 are provided so as to be aligned in the left-right direction orthogonal to the transport direction.

  Thereby, the top chain 71 can place the linear bar 124 of the container 1 on the transport surface 76 and can be stably pressed by the four engaging claws 73. The engaging claw 73 rises from the conveying surface 76 of the top chain 71 to the front side in the conveying direction by a predetermined angle, for example, 90 degrees, and presses the pressing surface 731 for pressing the bar 124 of the container 1. And an inclined surface 732 inclined to the side.

  As shown in FIG. 11B, each top chain 71 is circulated by a driven sprocket (sprocket) 77 provided on the carry-in port 4 side and a drive sprocket (sprocket) 74 provided on the carry-out port 5 side. To do. As a result, the engaging claws 73 provided on the pair of top chains 71 push the bar 124 and convey it. At this time, the bar 124 is placed on the conveying surface 76 of the pair of top chains 71 and is pressed by the pressing surface 731 of the engaging claw 73. When the bar 124 is pressed, the container 1 is pushed through the support portion 123, and the container 1 is conveyed in the conveyance direction. At this time, the bar 124 is pushed without rolling.

  In the vicinity of the driven sprocket 77, a loading guide 81 for guiding the bar 124 of the container 1 to the conveying surface 76 of the top chain 71 is provided. The pair of top chains 71 are connected to a pair of drive sprockets 74 having the same drive shaft as that of the electric motor, and rotate at the same speed.

  The carry-in guide 81 extends in the conveyance direction with the same width as the utility space 70 in the left-right direction between the pair of top chains 71. The carry-in guide 81 is formed by bending a single plate-like member. The carry-in guide 81 in the traveling direction extends from the height lower than the bar 124 included in the container 1 to the height substantially equal to the conveyance surface 76 of the top chain 71 and extends in the conveyance direction while being inclined upward. And the horizontal guide part 83 extended in a conveyance direction to the position beyond the driven sprocket 77 in a horizontal direction following the inclination guide part 82 is provided.

  In the present embodiment, the upper surface of the horizontal guide portion 83 is positioned above the transport surface 76 of the top chain 71 by a predetermined dimension, for example, 3 millimeters, and the upper surface of the horizontal guide portion 83 and the transport surface 76 of the top chain 71 are Step 84 is formed.

  As shown in FIG. 12A, the pair of transport rails 72 of the transport mechanism 7 are connected to a pair of carry-in rails 6 provided on the carry-in entrance 4 side and a pair of carry-out rails 8 provided on the carry-out exit 5 side. The carry-in rail 6 and the transport rail 72 are connected with the carry-in entrance 4 as a boundary, and form a second step portion 92 described later. The conveyance rail 72 and the carry-out rail 8 are connected with the carry-out port 5 as a boundary, and serve as a connection point between a third inclined portion 97 described later and the carry-out rail 8 which is a flat surface. The transport rail 72 is formed from the carry-in port 4 to the carry-out port 5 in the container washing / dropping / drying machine W.

  As shown in FIG. 12B, the wheel path composed of the carry-in rail 6, the carry rail 72, and the carry-out rail 8 forms a plurality of step portions and inclined portions. FIG. 12B exaggerates the dimensions in the height direction for ease of explanation.

  The carry-in rail 6 forms a first step portion 91 at the boundary with the floor surface FL. The first step 91 is formed by the thickness of the carry-in rail 6. For example, since one end of the carry-in rail 6 has a thickness of 3 mm, the first step portion 91 is at a height position of 3 mm from the floor surface FL. Further, the carry-in rail 6 forms a second step portion 92 at the boundary with the transport rail 72. One end of the transport rail 72 on the carry-in entrance 4 side is raised above the floor surface FL, and the second step portion 92 is formed by a difference in height from the carry-in rail 6. For example, since the thickness of one end of the transport rail 72 has a thickness of 3 mm and is 3 mm higher than the floor surface FL, the second step portion 92 is a step of 3 mm.

  Further, a first inclined portion 93 that is inclined downward along the transport direction is formed from the second step portion 92. A first flat portion 94 is formed from the terminal end of the first inclined portion 93. The first flat portion 94 is formed halfway through the washing zone 2 and the drop removal drying zone 3. The conveyance rail 72 has a second inclined portion 95 that is inclined upward in the conveyance direction from the end of the first flat portion 94, and a plurality of second inclined portions 95 are provided on the upper surface of the conveyance rail 72. An uneven portion 720 provided with a convex portion is formed. A second flat portion 96 continues from the end of the second inclined portion 95, and further, a third inclined portion 97 that is inclined downward along the transport direction is formed.

  The third inclined portion 97 continues to the boundary between the transport rail 72 and the carry-out rail 8. Furthermore, since the carry-out rail 8 has a thickness, the downstream end portion forms the third stepped portion 98 due to the thickness. In the present embodiment, the height of the third step 98 from the floor surface FL is 3 mm. In addition, you may adjust the thickness and inclination degree of each rail suitably.

  Note that another uneven portion may be provided on the transport rail 72 at the boundary between the cleaning zone 2 and the droplet removal drying zone 3 or at the droplet removal drying zone 3. Thereby, the rough thing of the water | moisture content adhering to the container 1 in the washing | cleaning zone 2 can be dropped and removed by the vibration at the time of the wheel 122 of the container 1 exceeding another uneven | corrugated | grooved part.

(Washing zone)
As shown in FIG. 13, the cleaning zone 2 includes two cleaning regions 21 continuing from the carry-in port 4 and a rinsing region 22 continuing downstream from the cleaning region 21.

  In each cleaning region 21, the cleaning nozzles 201 are provided in two rows and five stages as the cleaning nozzle portion 211. By these, cleaning water is sprayed from the upper part 101 to the lower part 103 of the container. Further, in the rinsing region 22, a five-stage rinsing nozzle 226 is provided in the finishing water pipe 224 that extends in the vertical direction as the rinsing nozzle portion 222. The rinsing nozzle 226 is configured by attaching a nozzle tip to an injection hole opened in the finishing water pipe 224. Thus, the finishing water is sprayed from the upper part 101 to the lower part 103 of the container.

  As shown in FIG. 14, in the cleaning region 21, a lower tank 212 is provided in the lower outer body WD below the floor surface FL, and the bottom surface of the lower tank 212 is set to one side in the left-right direction orthogonal to the transport direction. Tilt. As a result, wash water accumulates on one inclined side, and the wash water can be smoothly sent to the intermediate tank 213 by disposing the submersible pump 214 on one side. The lower tank 212 and the intermediate tank 213 can be manufactured, for example, by bending and welding a stainless steel plate material.

  Each cleaning region 21 sprays cleaning water from the cleaning nozzle 201 at a high pressure from the left-right direction toward the center. The cleaning water sprayed to the container 1 is received by the lower tank 212, sent to the intermediate tank 213 by the submersible pump 214, and sprayed again from the cleaning nozzle 201 by the cleaning water pump 215 from the intermediate tank 213. Accordingly, the cleaning water is circulated and used in the cleaning region 21.

(Drip removal drying zone)
As shown in FIG. 15, the droplet removal drying zone 3 includes a plurality of droplet removal drying regions along the conveyance direction of the container 1.

(Container movement in a container cleaning drip dryer)
Next, after the container 1 is carried into the container washing / dropping / drying machine W, the container 1 is dropped and dried by blowing air at a predetermined temperature after washing with washing water and rinsing with finishing water. A series of movements until the container 1 is unloaded from the container cleaning / deleting / drying machine W will be described. The operation of the submersible pump 214 in the cleaning zone 2, the cleaning water pump 215, the blowers 401 to 407 in the droplet removal drying zone 3, the top chain 71 of the transport mechanism 7, and the heat exchangers 501 to 503 are controlled by the control panel G. To do.

(Conveying containers to the container cleaning drip dryer)
As shown in FIG. 18, the container 1 is carried into the container washing / dropping dryer W from the carry-in port 4. A plurality of containers 1 are sequentially loaded into the container washing / deleting / drying machine W from the carry-in port 4 at a predetermined interval in the carrying direction, successively washed, removed and dried, and carried out from the carry-out port 5. Is done. In other words, the container cleaning / deleting / drying machine W cleans and drops / drys the container 1 by so-called continuous processing.

  The operation of the container 1 near the carry-in entrance 4 will be described with reference to FIGS. 19 and 20.

  As an outline, the operator moves the container 1 and places and pushes the wheels 122 of the container 1 on the pair of carry-in rails 6, thereby moving the wheels 122 of the container 1 from the pair of carry-in rails 6 to the pair of transport rails. Then, the container 1 is transferred to the container washing / dropping / drying machine W from the carry-in port 4.

  The bar 124 supported by the pair of support portions 123 provided on the bottom portion 12 of the loaded container 1 rides on the upper surface of the loading guide 81 and rolls the upper surface of the loading guide 81 in the conveying direction (clockwise in FIG. 20). ), Is dropped from the step 84 and placed on the transport surface 76 of the top chain 71. The bar 124 rolls (counterclockwise in FIG. 20) in a state where it is placed on the conveying surface 76 of the top chain 71, and makes the container 1 stand by.

  Then, the engaging claw 73 provided on the transport surface 76 of the driving top chain 71 engages with the bar 124 of the container 1 that has been waiting, and pushes the bar 124 in the transport direction, thereby moving the container 1 in the transport direction. Transport to. At this time, the wheels 122 of the container 1 are guided by a conveyance rail 72 extending in a straight line, and the container 1 is conveyed in the conveyance direction along the conveyance rail 72 by the conveyance mechanism 7.

  The state of FIG. 19 (A) is a state in which the operator pushes the container 1 and partially carries it into the carry-in port 4 of the container washing / dropping / drying machine W. The bar 124 is located at a position A in FIG. 20 and is in contact with the bottom 171 of the long hole 125 provided in the support portion 123. A distance HA between the upper side 172 of the long hole 125 which is the lower surface of the bottom 12 of the container 1 and the upper end of the bar 124 is, for example, about 47 mm. The bar 124 moves back and forth in the transport direction within the long hole 125.

  At this time, as shown in FIG. 19 (A), the wheel 122 on the front side of the container 1 passes over the first and second step portions 91 and 92 and the first inclined portion 93 and the first flat portion 94. Located on the border. The rear wheel 122 is positioned in front of the first step 91.

  While the operator further pushes the container 1 and the bar 124 moves from the position A to the position B in FIG. 20, the bar 124 contacts the inclined guide portion 82 of the carry-in guide 81. Since the bar 124 is vertically movable and rollable within the long holes 125 provided in the pair of support portions 123, the bar 124 comes into contact with the inclined guide 82 and rides on the inclined guide 82 while rolling, so that the horizontal guide It advances in the transport direction while rolling on the upper surface of the part 83 (clockwise in FIG. 20).

  The state of FIG. 19B is a state when the operator further pushes the container 1 to advance in the transport direction and the bar 124 has advanced to the position B of FIG. The bar 124 advances in the conveyance direction while rolling the upper surface of the horizontal guide portion 83 of the carry-in guide 81 in the conveyance direction (clockwise in FIG. 20). Further, the bar 124 moves upward away from the bottom 171 of the long hole 125 provided in the support portion 123, and the upper side 172 of the long hole 125, which is the lower surface of the bottom 12 of the container 1, and the upper end of the bar 124. The distance HB is smaller than the distance HA, for example, about 32 mm.

  At this time, as shown in FIG. 19B, the wheel 122 on the front side of the container 1 is located on the first flat portion 94 beyond the first inclined portion 93. The rear wheel 122 is positioned between the first step 91 and the second step 92.

  The carry-in guide 81 may be provided with a resin material at a location where the bar 124 abuts. In that case, when the operator pushes the container 1 vigorously and loads the container 1, the bar 124 comes into contact with the inclined guide portion 82 of the loading guide 81 or the bar 124 rolls on the horizontal guide portion 83 of the loading guide 81. It is possible to prevent the bar 124 from being damaged by rubbing and moving without moving.

  The state of FIG. 19C is a state when the operator further pushes the container 1 to advance in the transport direction, and the bar 124 has advanced to position C in FIG. While the bar 124 moves from the position B to the position C in FIG. 20, the bar 124 is pushed by the side 173 on the rear side of the long hole 125 of the support portion 123, and the horizontal guide portion 83 of the carry-in guide 81 is moved. The step 84 falls from the upper surface to the conveying surface 76 of the top chain 71. At this time, a falling sound is generated when the bar 124 falls. As will be described later, the falling sound of the bar 124 can be a signal to stop the operator from pushing the container 1.

  Then, when the operator stops pressing the container 1 by a signal, the bar 124 rolls (counterclockwise in FIG. 20) while being placed on the transport surface 76 of the top chain 71 driven in the transport direction. Will be around). Further, the bar 124 moves upward away from the bottom 171 of the long hole 125 provided in the support portion 123, and the upper side 172 of the long hole 125, which is the lower surface of the bottom 12 of the container 1, and the upper end of the bar 124. The distance HC is about 35 mm, for example. Then, the bar 124 keeps rolling to release the drive of the top chain 71 and keeps the container 1 on standby until the engaging claw 73 provided on the conveying surface 76 of the top chain 71 engages with the bar 124.

  At this time, as shown in FIG. 19C, the rear wheel 122 of the container 1 is positioned in front of the second step portion 92. Here, when the operator pushes the container 1, the rear wheel 122 is applied to the second step portion 92, so that it is difficult to touch the container 1 in order to get over the second step portion 92. The resistance of the feeling of pushing the container 1 can be a signal to stop the worker pushing the container 1 together with the falling sound of the bar 124.

  Even if there is a signal that the operator stops pressing the container 1, the container 1 is further pushed and moved, and the bar 124 is positioned downstream of the position C in FIG. Good.

  The state of FIG. 19D is a state when the engaging claw 73 provided on the conveying surface 76 of the top chain 71 to be driven engages with the bar 124 and the bar 124 has advanced to the position D in FIG. is there. As described above, the bar 124 is engaged with the engaging claws 73 by dropping and placing the bar 124 from the upper surface of the horizontal guide portion 83 of the carry-in guide 81 onto the conveying surface 76 of the top chain 71. It is arranged at a position where

  Then, the bar 124 with which the engagement claw 73 is engaged comes into contact with the front side 174 of the long hole 125. As a result, the bar 124 is engaged with the engaging claw 73 and pressed by the pressing surface 731, abuts against the front side 174 of the long hole 125, presses the container 1 through the support portion 123, and Transport in the transport direction. At this time, the distance HD between the upper side 172 of the long hole 125 which is the lower surface of the bottom 12 of the container 1 and the upper end of the bar 124 is the same as the distance HC, for example, about 35 mm.

  At this time, as shown in FIG. 19D, the front wheel 122 of the container 1 is positioned on the first flat portion 94. The rear wheel 122 reaches the first inclined portion 93 beyond the second step portion 92.

  In the state of FIG. 19C, when the bar 124 drops from the upper surface of the horizontal guide portion 83 of the carry-in guide 81 to the conveying surface 76 of the top chain 71, the bar 124 comes into contact with the conveying surface 76. Makes a falling sound. Further, since the rear wheel 122 is engaged with the second step portion 92, there is resistance to the feeling of pushing the container 1. By stopping the operator from pressing the container 1 using the falling sound and resistance as a signal, the bar 124 is placed on the transport surface 76 and is engaged with the engaging claw 73. That is, it is possible to confirm the timing at which the worker stops pressing the container 1 by sound and touch, and to make the container 1 stand by at an optimal position.

  At that time, since the rear wheel 122 is engaged with the second step portion 92, the container 1 can be prevented from moving forward. Thereby, it is possible to prevent the container 1 that the operator is to push in and carry in first and collide with the container 1 being conveyed.

  In this way, the worker places the container 1 in a predetermined position, in this embodiment, a position where the bar 124 makes a falling sound, and the wheel 122 on the rear side of the container 1 comes in front of the second step portion 92. Can be made to stand by in the state which suppressed moving the container 1 ahead. Then, the engaging claw 73 provided on the transport surface 76 of the top chain 71 to be driven is engaged with the bar 124 with respect to the standby container 1, and then the second stage is applied to the wheel 122 on the rear side of the container 1. The container 1 can be transported in the transport direction over the section 92.

  The rolling state of the bar 124 and the wheels 122 until the container 1 is loaded and conveyed will be described. When the container 1 is loaded from the carry-in port 4, the bar 124 rolls (clockwise in FIG. 19). The wheel 122 rolls (clockwise in FIG. 19). Next, when the container 1 is waiting, the bar 124 rolls (counterclockwise in FIG. 19), and the wheel 122 is stationary. When the conveyance of the container 1 is started, the bar 124 stops and the wheel 122 rolls (clockwise in FIG. 19).

  The position where the operator stops pressing the container 1 can also be known by the fact that the rear side surface portion 15 in the transport direction of the container 1 and the surface of the carry-in entrance 4 substantially coincide with each other in the transport direction. It may be.

  In addition, by allowing the bar 124 to move up and down within the long hole 125, regardless of changes in the height position of the top chain 71, the distance between the lower surface of the bottom 12 of the container 1 and the floor surface FL, etc. In the state where the container 1 is loaded and the bar 124 is placed on the conveying surface 76 of the top chain 71, the engaging claw 73 can be engaged with the bar 124 and the container 1 can be conveyed. Accordingly, the container 1 can be transported by engaging the bar 124 of the container 1 with the engaging claw 73 without being affected by the dimensional error at the time of manufacturing the container 1.

  In the present embodiment, since the engaging claws 73 are provided on the conveying surface 76 of the top chain 71 at a predetermined interval, for example, 2 m pitch in the conveying direction of the container 1, the container in which the bar 124 is engaged with the engaging claws 73. 1 is conveyed at substantially equal intervals at intervals of 2 m.

  Next, referring to FIG. 21, when the container 1 is carried in from the carry-in entrance 4, the engagement claw 73 passes through the step 84 of the horizontal guide portion 83 of the carry-in guide 81, but the engagement claw 73 still remains. A case where the worker presses the container 1 in the transport direction and the bar 124 is engaged with the passing engagement claw 73 when it is in the vicinity of the step 84 of the horizontal guide portion 83 will be described. Note that, at the positions F, G, and H in FIG. 21, the support portion 123 is omitted for easy viewing.

  As shown in FIG. 21, the operator pushes the container 1 at a speed higher than that of the top chain 71 until the bar 124 comes to the position E in FIG. Move. At this time, the container 1 moves the container 1 further to the back than the position where the worker stops pushing the container 1 by a signal.

  The operator further pushes the container 1 to move it on the transport surface 76 of the top chain 71 that is driven in the direction of arrow c. The bar 124 is pushed while coming into contact with the rear side 173 of the long hole 125 provided in the support portion 123. Further, since the bar 124 is placed on the transport surface 76, the bar 124 is positioned above the bottom 171 of the long hole 125 provided in the support portion 123, and the interval HE from the upper end of the bar 124 to the upper side 172 of the long hole 125 is For example, it is about 35 mm.

  Thereafter, when the operator further pushes the container 1 at a speed faster than the top chain 71, the bar 124 that can move up and down is pushed while abutting against the side 173 on the rear side of the long hole 125, and the position shown in FIG. As shown in F, it moves while rolling the inclined surface 732 of the engaging claw 73 obliquely upward. Further, since the bar 124 is placed on the inclined surface 732 of the engaging claw 73, the interval HF from the upper end of the bar 124 to the upper side 172 of the long hole 125 is the inclined surface 732 of the engaging claw 73 of the bar 124. Becomes smaller as it moves while rolling upward (clockwise in FIG. 21).

  Further, when the operator pushes the container 1 at a speed higher than that of the top chain 71, the bar 124 is pushed while being in contact with the rear side 173 of the long hole 125, and the bar 124 is at the position G in FIG. The apex 733 of the engaging claw 73 is reached. The bar 124 is positioned above the bottom side 171 of the long hole 125, and the interval HG from the upper end of the bar 124 to the upper side 172 of the long hole 125 is, for example, 5 mm. Even when the bar 124 is placed on the apex 733 of the engaging claw 73, a gap is formed between the upper end of the bar 124 and the upper side 172 of the long hole 125.

  Thereafter, when the operator further pushes the container 1 at a speed higher than that of the top chain 71, the bar 124 that has overcome the apex portion 733 of the engaging claw 73 falls onto the conveying surface 76 as shown at a position H in FIG. . At this time, a falling sound is generated when the bar 124 falls. The falling sound of the bar 124 can be a signal to stop the operator from pushing the container 1. Thereafter, the pressing surface 731 of the engaging claw 73 provided on the conveying surface 76 of the top chain 71 to be driven comes into contact with and engages with the bar 124. The bar 124 with which the engaging claw 73 is engaged comes into contact with the front side 174 of the long hole 125. As a result, the bar 124 is pushed by being engaged with the engaging claw 73, abuts against the side 174 on the front side of the long hole 125, pushes the container 1 through the support portion 123, and moves the container 1 in the transport direction. Transport. At this time, the distance HH between the upper side 172 of the elongated hole 125 that is the lower surface of the bottom 12 of the container 1 and the upper end of the bar 124 is the same as the distance HC in FIG. 20, and is about 35 mm, for example.

  As described above, even when the engaging claw 73 passes without being engaged with the bar 124 and the container 1 that is sequentially transported into the container cleaning / deleting / drying machine W has an empty space, A person pushes the container 1 at a speed faster than that of the top chain 71 and moves the container 1 to engage the bar 124 with the engaging claw 73 that has passed, thereby transporting the container 1. By doing so, the container 124 can be transported while the bar 124 is engaged with the engaging claw 73 that has passed without the bar 124 being engaged.

  Even when the bar 124 is placed on the apex portion 733 of the engaging claw 73, the upper side 172 of the long hole 125 and the upper end of the bar 124 form a predetermined interval, for example, 5 mm. Thereby, the bar 124 can get over the engaging claw 73 without contacting the bottom 12 of the container 1. That is, the apex portion 733 of the engaging claw 73 is configured such that the distance from the upper side 172 formed by the lower surface of the bottom portion 12 of the container 1 is larger than the diameter of the bar 124.

  Further, the predetermined interval in the transport direction of the engaging claw 73 provided on the transport surface 76 of the top chain 71 is determined by the length of the container 1 in the transport direction and the container cleaning / dehydrating dryer W cleaning the container 1 per hour. It is set according to the ability to remove drops and dry. For this reason, the container 1 is transported by engaging the bar 124 with the engaging claw 73 that has passed without being engaged with the bar 124 and transports the container 1, so that the container 1 of the container washing and removing dryer W can be moved per hour. The ability to wash and remove droplets can be demonstrated without waste.

(Washing of containers by washing zone)
As shown in FIG. 4 and FIG. 13, the container 1 carried in from the carry-in port 4 is removed in the washing region 21 of the washing zone 2 with washing water in which detergent is mixed with dirt adhering to the container 1. In the rinsing region 22, the water is rinsed with finishing water which is tap water. Accordingly, when the container 1 exits the cleaning zone 2, the cleaning water almost flows down and is transported to the droplet removal drying zone 3 in a state where water mainly composed of finishing water is adhered.

  In the cleaning region 21, high-temperature steam supplied from the boiler 216 is blown into the cleaning water stored in the intermediate tank 213 and heated to a predetermined temperature, for example, about 50 degrees C. Then, the cleaning water heated to a predetermined temperature is sent from the intermediate tank 213 to the cleaning nozzle unit 211 by the cleaning water pump 215, and the cleaning water is jetted to the container 1. The container 1 can be heated by washing the container 1 with washing water having a predetermined temperature.

  In the rinsing region 22, the high-temperature steam supplied from the boiler 216 by the mixing valve 225 is mixed with the finishing water and heated to a predetermined temperature, for example, 80 degrees C. The container 1 can be further heated by spraying the finishing water heated to a predetermined temperature into the container 1 and rinsing the container 1 with the finishing water. By heating the container 1 in the cleaning region 21 and the rinsing region 22, it is possible to promote the dewatering and drying of the water adhering to the container 1 in the later-described droplet removing and drying zone 3.

(Dropping and drying the container by the drop removal drying zone)
As shown in FIG. 3, while the container 1 that has been cleaned and rinsed in the cleaning zone 2 is transported by the transport mechanism 7 in the droplet removal drying zone 3, the heat exchangers 501 to 503 are transferred from the droplet removal drying means 301 to 308. The air heated at a predetermined temperature, for example, 80 ° C. air is injected. And the moisture adhering to the container 1 is removed by wind pressure with the air of the predetermined | prescribed temperature injected from the droplet removal drying means 301-308 to the container 1, and it dries with heat. In addition, since the droplet removal drying means 309 and 310 are not connected to the heat exchanger, air at a temperature lower than a predetermined temperature, for example, 70 ° C. is injected, and moisture attached to the container 1 is removed by wind pressure. It is dried by heat. Thereby, the droplet removal drying means 301 to 310 remove water adhering to the container 1.

  As shown in FIG. 22 (A), a pair of wide area air nozzles 340, which are droplet removal drying means 301, are disposed in the container from the left-right direction to the center in the transport direction with respect to the container 1 passing through the preliminary droplet removal drying area 30. Air having a predetermined temperature is sprayed over the entire region from the top to the bottom of the 1. Thereby, the moisture adhering to the container 1 can be roughly removed from the upper part 101, the middle part 102, and the lower part 103 of the container. Moreover, the location which the air of predetermined temperature hits in the container 1 is heated.

  In the present embodiment, as shown in FIG. 15, in the preliminary droplet removal drying area 30, the upper portions of the pair of wide area air nozzles 340 are inclined toward the carry-in entrance 4 in the transport direction. As a result, in the preliminary droplet removal drying area 30, air at a predetermined temperature is jetted sequentially from the upper part 101 of the container to be transported to the lower part 103 of the container in accordance with the fall of the moisture adhering to the container 1, and is removed by the wind pressure. Can be dripped and dried by heat.

  Moreover, the location where the air of predetermined temperature hits in the container 1 can be heated, and the droplet removal drying effect in the subsequent droplet removal drying regions 31 to 33 can be enhanced. Furthermore, since the container 1 is heated and the temperature rises, the moisture attached to the container 1 can be evaporated and dried even when air at a predetermined temperature is not sprayed toward the container 1. .

  As shown in FIG. 22 (B), one of the straight air nozzles 311 of the pair of straight air nozzles 311 and 312 which are the droplet removing and drying means 302 is applied to the container 1 passing through the upper droplet removing and drying area 31. Then, air at a predetermined temperature is jetted obliquely upward from the right side in the transport direction of the container 1 toward the lower surface of the ceiling portion 11 of the container 1. The other straight air nozzle 312 injects air at a predetermined temperature obliquely upward from the right side in the transport direction of the container 1 toward the upper shelf 18 of the container 1. Thereby, the moisture adhering to the lower surface of the ceiling part 11 and the upper shelf 18 can be blown off to the left in the transport direction of the container 1 by the wind pressure of air at a predetermined temperature to be removed and dried by heat.

  Further, as shown in FIG. 15, a pair of rectilinear air nozzles 319 and 320 that are droplet removing and drying means 305 are disposed on the front side of the container 1 from the front with respect to the container 1 that passes through the upper droplet removing and drying area 31. 15 and air of a predetermined temperature are jetted toward the ceiling portion 11. As a result, moisture attached to the front side surface portion 15 in the transport direction of the container 1 and the upper surface of the ceiling portion 11 of the container 1 is blown off by the wind pressure of air at a predetermined temperature to be removed and dried by heat. Can do.

  In the upper drop removal drying area 31, a portion of the container 1 that has been exposed to air at a predetermined temperature is heated, and the drop removal drying effect in the middle drop removal drying area 32 and the lower drop removal drying area 33 can be enhanced. . Further, since the temperature of the container is increased by heating the container, moisture attached to the container can be evaporated and dried even when air at a predetermined temperature is not sprayed toward the container.

  As shown in FIG. 22C, for the container 1 that passes through the middle drop removal drying area 32, one of the straight advance air nozzles 313 and 314 as the drop removal drying means 303 is a container. The air at a predetermined temperature is jetted obliquely upward from the right side in the conveying direction 1 toward the lower shelf 19 of the container 1. Further, the other straight air nozzle 314 of the pair of straight air nozzles 313 and 314 serving as the droplet removing and drying means 303 injects air at a predetermined temperature obliquely downward from the right side toward the upper surface of the bottom 12 of the container 1. . Thereby, the moisture adhering to the lower shelf 19 and the upper surface of the bottom portion 12 of the container 1 is blown off to the left side in the transport direction of the container 1 by the wind pressure of air at a predetermined temperature to be removed and dried by heat. it can.

  Further, as shown in FIG. 15, a pair of rectilinear air nozzles 321 and 322 serving as a droplet removing and drying means 306 are provided on the side surface on the rear side of the container 1 from the rear side. Air of a predetermined temperature is jetted toward the part 15 and the ceiling part 11. Further, the pair of rectilinear air nozzles 323 and 324 that are the droplet removing and drying means 307 inject air at a predetermined temperature from the front toward the front side portion 15 of the container 1 and the ceiling portion 11 of the container.

  Thereby, the moisture adhering to the upper side surface of the ceiling portion 11 of the container 1 and the front side surface portion 15 and the rear side surface portion 15 in the transport direction of the container 1 is blown off by the wind pressure of air at a predetermined temperature. Drops can be removed and dried by heat.

  In the middle drop removal drying region 32, a portion of the container 1 that has been exposed to air of a predetermined temperature can be heated to enhance the drop removal drying effect in the lower drop removal drying region 33 in the subsequent stage. Further, since the temperature of the container is increased by heating the container, moisture attached to the container can be evaporated and dried even when air at a predetermined temperature is not sprayed toward the container.

  In the upper drop removal drying area 31 and the middle drop removal drying area 32, the straight air nozzles 311 to 311 are moved from one side toward the ceiling 11, the upper shelf 18, the lower shelf 19, and the bottom 12 of the container 1 in order. Air is injected by 314. Only one straight air nozzle 311, 312 is connected to one blower 402, and only one straight air nozzle 313, 314 is connected to one blower 404. Therefore, more concentrated air can be ejected, and moisture adhering to the container 1 can be more effectively brought from one side to the other side. In this embodiment, the rectilinear air nozzles 311 to 314 can inject air from the right side and draw water more effectively to the left side.

  As shown in FIG. 22 (D), with respect to the container 1 passing through the lower drop removal drying area 33, the drop removal drying means 304 is provided on the left side in the transport direction of the container 1, and the lower drop removal drying area 33 is Air of a predetermined temperature is jetted from the left side to the right side in the conveying direction of the container 1 that passes through the container 1.

  Of the four rectilinear air nozzles 315 to 318 that are the droplet removal drying means 304, the rectilinear air nozzle 315 injects air at a predetermined temperature obliquely upward toward the vicinity of the ceiling 11 of the container 1. The rectilinear air nozzle 316 injects air at a predetermined temperature obliquely upward toward a height position near the upper shelf 18 of the container 1. The rectilinear air nozzle 317 injects air having a predetermined temperature obliquely upward toward the vicinity of the shelf 19 on the lower side of the container 1. The rectilinear air nozzle 318 injects air at a predetermined temperature obliquely downward toward the bottom 12 of the container 1.

  The straight air nozzles 315 to 318 serving as the droplet removing and drying means 304 can inject air over the entire area in the vertical direction of the storage unit 17 of the container 1.

  In the upper drop removal drying area 31 and the middle drop removal drying area 32, the moisture removed to the left in the transport direction of the container 1 by the drop removal drying means 302, 303 is removed by the drop removal drying means 304 in the lower drop removal drying area 33. By injecting air of a predetermined temperature into the container 1 from the left side to the right side in the transport direction of the container 1, moisture can be removed by wind pressure, and moisture attached to the container 1 can be dried by heat.

  Further, the pair of rectilinear air nozzles 327 and 328 serving as the droplet removing and drying means 309 are air having a temperature lower than a predetermined temperature, for example, 70 degrees C., from the lower side of the bottom 12 of the container 1 toward the lower surface of the bottom 12. Inject. As a result, the lower surface of the bottom 12 of the container 1 is subjected to drop removal drying.

  Further, the pair of straight air nozzles 329 and 330 serving as the droplet removing and drying unit 310 are lower than a predetermined temperature from the position corresponding to the lower part 103 of the container from the left and right sides in the transport direction of the container 1 to the vicinity of the caster 121. Inject air of temperature. As a result, the pair of rectilinear air nozzles 329 and 330 removes and dries around the caster 121. Since the droplet removal drying means 309 and 310 are not connected to a heat exchanger and inject air having a temperature lower than a predetermined temperature, casters made of rubber, resin, etc., which are relatively heat-sensitive in the container 1, are used. 121, in particular, deterioration of the wheels 122 and the like due to heat can be suppressed.

  Further, as shown in FIG. 15, a pair of rectilinear air nozzles 325 and 326 that are droplet removing and drying means 308 are provided on the side surface on the rear side of the container 1 from the rear side. Air of a predetermined temperature is jetted toward the part 15 and the ceiling part 11. Thereby, the water | moisture content adhering to the side part 15 and the ceiling part 11 of the rear side of the container 1 can be dedrop-dried. Furthermore, the container 1 receives air of a predetermined temperature jetted from the rear by the droplet removal drying means 308 and accelerates forward in the transport direction. As a result, the container 1 leaves the engagement claw 73 and precedes the front in the transport direction, and details will be described later.

  Similar to the drop removal drying means 308, the drop removal drying means 306 injects air at a predetermined temperature from the rear toward the side part 15 and the ceiling part 11 on the rear side of the container 1. However, for the container 1 receiving the air jet from the droplet removal drying means 306, the droplet removal drying means 307 has a predetermined temperature from the front toward the side portion 15 and the ceiling portion 11 on the front side of the container 1. Since the air is jetted, the forces received by the air jetted from the drop removal drying means 306 and the drop removal drying means 307 are balanced and the container does not accelerate forward.

  Further, as shown in FIGS. 6A and 6B, a front door 161 and a rear door 162 are provided on both ends of the side portion 15 on the front side and the rear side of the container 1. 22 (A) to 22 (D), the front door portion 161 on the left side of the left and right directions orthogonal to the transport direction of the container 1 is the left side of the wide area air nozzle 340 in the preliminary droplet removal drying area 30. The distance from the straight air nozzles 315 to 318 in the lower droplet removal drying area 33 is short.

  In addition, of the left and right directions orthogonal to the transport direction of the container 1, the front door portion 161 on the right side is the right side of the wide area air nozzle 340 in the preliminary drop removal drying area 30 and the straight air nozzle in the upper drop removal drying area 31. 311, 312, the distance from the straight air nozzles 313, 314 in the middle drop removal drying region 32 is short. For this reason, the wind pressure of the injected air at a predetermined temperature is unlikely to attenuate and the temperature is unlikely to decrease. Therefore, the front door portion 161 on both sides in the left-right direction perpendicular to the transport direction of the container 1 is relatively dedrided and dried. Cheap. Similarly, the rear door 162 on both sides in the left-right direction, which is orthogonal to the conveyance direction of the container 1, is also easy to remove and dry.

(Conveying containers from container washing and drip dryer)
As shown in FIG. 23, the container 1 is carried out from the container washing / dropping / drying machine W through the carry-out port 5. The plurality of containers 1 that are sequentially carried in from the carry-in port 4 at a predetermined interval are successively carried out from the carry-out port 5 after being successively washed and subjected to droplet removal drying.

  Specifically, as shown in FIG. 23A, the bar 124 of the container 1 advances by being pushed by the engaging claw 73 on the conveying surface 76. At this time, the front wheel 122 reaches the carry-out rail 8, and the rear wheel 122 advances in the transport direction through the third inclined portion 97 that is inclined downward.

  Next, as shown in FIG. 23B, the bar 124 of the container 1 reaches the end of the top chain 71. At this time, the rear wheel 122 advances through the third inclined portion 97 in the transport direction. At the end of the top chain 71, the engaging claw 73 rotates along with the rotation of the drive sprocket 74. At this time, the engaging claw 73 can push the bar 124 of the container 1 forward by the pressing surface 731 of the engaging claw 73 with respect to the top chain 71.

  Next, as shown in FIG. 23C, since the bar 124 of the container 1 is not pressed when it is separated from the engaging claw 73, the container 1 pushes the engaging claw 73 to release the bar 124 of the container 1. Stops after proceeding in the transport direction with slight inertia due to pressure. At this time, the bar 124 comes into contact with the bottom 171 of the long hole 125 included in the support portion 123.

  At this time, since the front wheel 122 exceeds the third stepped portion 98 and the rear wheel 122 is placed on the third inclined portion 97, the droplet removal drying in which the container 1 is rearward in the transport direction. Returning to zone 3 can be suppressed. In addition, you may provide the uneven | corrugated | grooved part similar to the uneven | corrugated | grooved part 720 in the path | route of the wheel 122 so that the container 1 may not advance too much by inertia due to the exterior of the carrying-out port 5.

(Container transport speed and droplet removal drying in the droplet removal drying zone)
With reference to FIGS. 24A to 24E, the conveyance of the container 1 from the vicinity of the upper droplet removal drying region 31 to the vicinity of the lower droplet removal drying region 33 and the droplet removal drying will be described. The containers 1001, 2001, 3001, 4001, and 5001 are transported when the engaging claw 73 provided on the transport surface 76 of the top chain 71 is engaged with the bar 124 of each container 1 and the top chain 71 is driven. The

  Since the top chain 71 is driven by an electric motor as a drive source, the speed at which the top chain 71 is driven is switched between high speed driving and low speed driving by an inverter that controls the electric motor. Then, the high-speed driving and the low-speed driving are repeated in a predetermined cycle, for example, one cycle in which the high-speed driving is 20 seconds and the low-speed driving is 40 seconds.

  When the bar 124 is pushed and conveyed by the engaging claw 73 of the top chain 71, the container 1 moves at a high speed when the top chain 71 is driven at a high speed, and moves at a low speed when the top chain 71 is driven at a low speed. Further, when the container 1 receives the air sprayed from the droplet removal drying means 308 serving as the acceleration means on the side surface portion 15 on the rear side of the container 1, the container 1 accelerates and the bar 124 moves away from the engaging claw 73 in the transport direction. Proceed forward. In FIG. 24, the top chain 71 is omitted for easy understanding.

  In FIG. 24A, the top chain 71 is driven at high speed, and the containers 1001, 2001, 3001, 4001 are moving at high speed. At this time, since each of the containers 1001, 2001, 3001, 4001 is transported with the bars 1124, 2124, 3124, 4124 engaged with the provided engaging claws 73, the containers 1001, 2001, 3001, 4001 The interval is equal to the interval between the engaging claws 73 and is a predetermined interval, for example, an interval s that is 2 m. In addition, the wheel 1122 on the rear side of the container 1001 after the completion of the droplet removal and drying is located at a position past the concavo-convex portion 720 serving as a speed reduction unit.

  Further, the droplet removal drying means 302, 303, 304, 309, and 310 are generally located near the front ends of the front door portions 4161, 3161, and 2161 of the containers 4001, 3001, and 2001 that move at high speed, and air at a predetermined temperature Spraying.

  Further, as described above, the front door portions 2161, 3161, 4161 and the rear door portions 2162, 3162, 4162 attached to both sides in the left-right direction orthogonal to the transport direction of the containers 2001, 3001, 4001 are relatively excluded. Easy to drip dry.

  When the front doors 2161, 3161, 4161, etc., which are relatively easy to remove the droplets, are removed by drying, the containers 2001, 3001, 4001 can be sufficiently removed even if they are moved at a high speed. , 3001, 4001 can be shortened in time required for drop-drying.

  At this time, the droplet removal drying means 308 generally injects air at a predetermined temperature onto the side surface portion 2015 and the ceiling 2011 on the rear side of the container 2001. As a result, the container 2001 is pushed from behind and further accelerated from the high-speed movement, and the bar 2124 moves away from the engaging claw 73 and starts to move to a preceding movement that moves at a higher speed than the high-speed movement. That is, the droplet removal drying means 308 also functions as an acceleration means. When the container 2001 accelerates and the bar 2124 moves away from the engaging claw 73, the bar 2124 rolls and moves in the transport direction.

  In the state of FIG. 24B, the top chain 71 starts to shift from high speed driving to low speed driving. At this time, the containers 1001, 3001, and 4001 have the bars 1124, 3124, and 4124 pushed by the engaging claws 73, and start to move from high speed movement to low speed movement. On the other hand, in the container 2001, the bar 2124 is separated from the engaging claw 73 by air of a predetermined temperature jetted from the droplet removal drying means 308 being jetted to the side face portion 2015 on the rear side of the container 1, so that the high speed. The movement has shifted to a preceding movement that moves at a faster speed. Thereby, the space | interval with the front container 1001 shrinks to the space | interval v smaller than the space | interval s, for example, 1.5 m, and the space | interval with the back container spreads to the space | interval t larger than the space | interval s, for example, 2.5 m.

  Further, the droplet removal drying means 302 generally injects air at a predetermined temperature near the boundary between the front door portion 4161 and the storage portion 4017 of the container 4001, and the droplet removal drying means 303 is roughly the front door of the container 3001. Air having a predetermined temperature is injected near the boundary between the portion 3161 and the storage portion 3017.

  The droplet removal drying means 304 injects air at a predetermined temperature near the boundary between the front door portion 2161 and the storage portion 2017 of the container 2001, and the droplet removal drying means 309 is provided on the lower surface of the bottom 2012 of the container 2001. Air having a temperature lower than a predetermined temperature is jetted near the front end, and the droplet removal drying means 310 jets air having a temperature lower than the predetermined temperature to a position in front of the wheel 2122 on the front side of the container 2001.

  Since the top chain 71 is driven at a low speed in the state of FIG. 24C, the containers 1001, 3001, 4001 are moved at a low speed by the bars 1124, 3124, 4124 being pushed by the engaging claws 73. On the other hand, in the container 2001, the front wheel 2122 reaches the uneven portion 720, and the uneven portion of the uneven portion 720 becomes resistance to rolling of the front wheel 2122, and the container 2001 stops after being decelerated. The distance from the front container 1001 extends to a distance w larger than the distance v, for example, 1.8 m, and the distance from the rear container 3001 is reduced to a distance u smaller than the distance t, for example, 2.2 m.

  Further, the droplet removal drying means 302 roughly injects air of a predetermined temperature into the storage portion 4017 of the container 4001 that moves at a low speed, and the droplet removal drying means 303 generally applies a predetermined amount to the storage portion 3017 of the container 3001 that moves at a low speed. The air of the temperature of is jetted. The storage units 3017 and 4017 of the containers 3001 and 4001 receive air at a predetermined temperature while moving at a low speed, and thus are effectively subjected to droplet removal and drying.

  On the other hand, in the container 2001, until the engaging claw 73 is engaged with the bar 2124 of the container 2001, the droplet removal drying means 304 is predetermined within the entire area in the vertical direction of the storage portion 2017 of the container 2001 that is stopped. Air having a temperature is jetted, and the droplet removal drying means 309 jets air having a temperature lower than a predetermined temperature to the lower surface of the bottom 2012 of the stopped container 2001. Thereby, until the engaging claw 73 is engaged with the bar 2124 of the container 2001, the entire area in the storage portion 2017, the lower surface of the bottom portion 2012 of the container 2001, and the container 2001 are stopped. It is possible to effectively remove and dry the existing bar 2124.

  Further, while the container 2001 is stopped, the droplet removal drying unit 310 injects air having a temperature lower than a predetermined temperature between the front wheel 2122 and the rear wheel 2122 of the container 2001. As a result, air having a temperature lower than a predetermined temperature is not directly injected to the front wheel 2122 and the rear wheel 2122, so even if the container 2001 is stopped, the front wheel 2122 and the rear wheel Deterioration due to heat of the rubber and the resin material used for 2122 can be suppressed.

  Further, since the droplet removal drying means 310 is disposed on both sides in the left-right direction orthogonal to the transport direction, air having a temperature lower than a predetermined temperature injected between the front wheel 2122 and the rear wheel 2122. May collide in the vicinity of the lower surface of the bottom portion 2012 of the container 2001 and change the flow in the vertical direction to promote the drip-drying of moisture attached to the lower surface of the bottom portion 2012 of the container 2001. it can.

  From the state shown in FIG. 24A to the state shown in FIG. 24C, the container 2001 is sprayed with air at a predetermined temperature on the rear side surface 2015 by the droplet removal drying means 308 in the state shown in FIG. 24A, the front wheel 2122 starts to be engaged with the concave and convex portion 720 as the vehicle moves past the position shown in FIG. 24B and approaches the position shown in FIG. The unevenness of the uneven portion 720 becomes a rolling resistance of the front wheel 2122, and the container 2001 decelerates. Then, the container 2001 stops in the vicinity where the droplet removal drying means 304, 309, and 310 are located approximately at the center in the transport direction of the container 2001.

  While the container 2001 is decelerating, the droplet removal drying means 304 injects air at a predetermined temperature over the entire area in the vertical direction of the storage portion 2017 of the container 2001. The drop removal drying means 309 injects air having a temperature lower than a predetermined temperature to the bottom of the bottom 2012 of the container 2001. The air at a predetermined temperature injected into the container 2001 is slowed down by the container 2001, so that the amount of air at the predetermined temperature injected into the same location per time increases, and the amount of heat is given to the same location. Since the time becomes longer, it is possible to effectively remove and dry.

  Further, while the container 2001 is decelerating, the droplet removal drying means 310 disposed on both sides in the left-right direction orthogonal to the transport direction has a temperature lower than a predetermined temperature in the vicinity of the front wheels 2122 on the left and right sides of the container 2001. Air is being injected. In the meantime, the wheel 2122 rolls so that the specific part of the ground contact surface of the wheel 2122 does not remain in contact with the transport rail 72. Therefore, the water adhering to the entire rolling contact surface that is the ground contact surface of the front wheels 2122 on both the left and right sides can be effectively removed and dried. And since the air injected from the droplet removal drying means 310 is air of temperature lower than predetermined temperature, the deterioration by the heat | fever of the rubber | gum used for the wheel 122 and the resin material can be suppressed.

  In addition, after the front wheel 2122 passes in front of the droplet removal drying means 310, air having a temperature lower than a predetermined temperature is dropped between the front wheel 2122 and the rear wheel 2122. Injected from 310. Since the droplet removal drying means 310 is disposed on both sides in the left-right direction orthogonal to the transport direction, air having a temperature lower than a predetermined temperature injected between the front wheel 2122 and the rear wheel 2122 is: By colliding in the vicinity of the lower surface of the bottom portion 2012 of the container 2001 and changing the flow in the vertical direction, it is possible to promote the removal of water adhering to the lower surface of the bottom portion 2012 of the container 2001.

  Since the bar 2124 of the container 2001 is rolling until the container 2001 is decelerated and stopped after the preceding movement, the droplet is dried and sprayed from the drying unit 309 to the lower surface of the bottom part 2012 of the container 2001. The entire bar 2124 can be effectively subjected to drop-drying with air having a temperature lower than a predetermined temperature.

  That is, when the bar 2124 is pressed by the pressing surface 731 of the engaging claw 73, the bar 2124 does not roll, and the bar 2124 adheres to a place where the pressing surface 731 and the transport surface 76 are in contact with each other. Moisture is difficult to remove and dry. However, since the bar 2124 is rolling, the moisture adhering to the entire rolling surface, which is the outer peripheral surface of the bar 2124, can be effectively subjected to droplet removal drying with air having a temperature lower than a predetermined temperature.

  In the state of FIG. 24D, the top chain 71 is still driven at a low speed. Therefore, the containers 2001, 3001, 4001, and 5001 move at low speed by the bars 2124, 3124, 4124, and 5124 being pushed by the engaging claws 73. Accordingly, the intervals between the containers 2001, 3001, 4001, and 5001 are all the interval s again. In addition, the container 1001 that has been subjected to droplet removal and drying is carried out from the carry-out port 5.

  Further, the droplet removal drying means 302, 303, and 304 inject air at a predetermined temperature to the rear door portions 2162, 3162, and 4162 that move at low speeds and in the vicinity thereof. Since the containers 2001, 3001, and 4001 receive air at a predetermined temperature while moving at a low speed, the containers 2001, 3001, and 4001 are effectively subjected to drop removal drying.

  In addition, while the container 2001 is moving at a low speed, the temperature is lower than a predetermined temperature in the vicinity of the rear wheels 2122 on the left and right sides of the container 2001 from the droplet removal drying means 310 disposed on both sides in the left and right direction orthogonal to the transport direction. Air of temperature is being jetted. In the meantime, the wheel 2122 rolls so that the specific part of the ground contact surface of the wheel 2122 does not remain in contact with the transport rail 72. Therefore, moisture adhering to the entire rolling contact surface, which is the ground contact surface of the rear wheels 2122 on both the left and right sides, can be effectively removed and dried. And since the air injected from the droplet removal drying means 310 is air of temperature lower than predetermined temperature, the deterioration by the heat | fever of the rubber | gum used for the wheel 122 and the resin material can be suppressed.

  In the state of FIG. 24E, the top chain 71 has shifted from the low speed drive to the high speed drive, and returns to the same state as in FIG. Therefore, the containers 2001, 3001, 4001, and 5001 are moving at high speed. At this time, the containers 2001, 3001, 4001, and 5001 are transported by pressing the bars 2124, 3124, 4124, and 5124 by the engaging claws 73 provided at a predetermined interval, for example, an equal interval of 2 m. The intervals between the containers 2001, 3001, 4001, 5001 are equal and become the interval s.

  In the present embodiment, the timing at which the containers 2001, 3001, 4001, and 5001 shift from the low-speed movement to the high-speed movement is during the shift from FIG. 24 (D) to FIG. 24 (E). Specifically, after the droplet removal drying means 302 to 310 inject air of a predetermined temperature toward the ends of the rear door portions 2162, 3162, and 4162, the containers 2001, 3001, 4001, and 5001 are slow. The timing for shifting from movement to high-speed movement may be advanced.

  For example, after injecting air at a predetermined temperature to the rear side surfaces 2015, 3015, and 4015 on the rear side of the containers 2001, 3001, and 4001, the containers 2001, 3001, 4001, and 5001 may be shifted from low-speed movement to high-speed movement. Good. By doing so, after the storage parts 2017, 3017, and 4017 of the containers 2001, 3001, 4001, and 5001 that are difficult to dry are dried, the rear door parts 2162, 3162, and 4162 that are easy to dry are replaced with the containers 2001, 3001, The number of containers 1 that can be processed by dropping the droplets while moving 4001 at a high speed, shortening the time taken to carry containers 2001, 3001, 4001, and 5001 from the carry-in port 4 and unload from the carry-out port 5. Can be increased.

  Thereafter, the operations shown in FIGS. 24A to 24E are repeated for the containers 1 that are sequentially conveyed.

  In this way, in FIGS. 24B to 24D, when the top chain 71 is driven at a low speed, the containers 3001 and 4001 moving at a low speed are connected to the front door portions 3161 and 4161 and the storage portions 3017 and 4017. Drop removal drying is performed by the drop removal drying means 303 and 302 from the vicinity of each boundary to the rear door portions 3162 and 4162. As a result, the containers 3001 and 4001 are effectively subjected to droplet removal drying.

  As described above, the container 1 transported at equal intervals is subjected to drop removal drying while being transported, and the transported container 1 is moved in advance by air of a predetermined temperature ejected from the droplet removal drying means 308. It is decelerated by the uneven part 720 and stopped.

  The storage unit 17 in which the outside and the inside communicate with each other in the left-right direction orthogonal to the transport direction of the container 1 includes an upper shelf 18 and a lower shelf 19 that are a combination of a long pipe 182 and a short pipe 181. Since the storage unit 17 has a distance between both ends in the length direction of the short pipe 181 (see FIG. 8) on the provided (see FIG. 6), it is ejected from the droplet removal drying means 302, 303, 304. The air having a predetermined temperature tends to attenuate the wind pressure in the storage unit 17 and the temperature tends to decrease. For this reason, the storage unit 17 is difficult to remove and dry.

  The amount of air at a predetermined temperature that is sprayed to the same location per hour is reduced by drying the storage unit 17 that is difficult to remove and dry while the container 1 is being decelerated and stopped. In addition, since the time for applying the amount of heat to the same location becomes longer, the moisture attached to the container 1 can be efficiently removed. In addition, since the concentrated air nozzle member 300 is attached to the droplet removal drying means 302 and 303, the wind pressure of the air at a predetermined temperature sprayed from the droplet removal drying means 302 and 303 is not easily attenuated, and the container 1 storage section It is easy to remove the water adhering to 17.

  Further, by removing the water adhering to the container 1, in particular by sufficiently removing the water adhering to the lower part 103 or the bottom 12 of the container 1, the water adhering to the container 1 is removed after the container 1 is carried out from the carry-out port 5. It can suppress falling to the floor surface FL of a facility. Moreover, since the water | moisture content adhering to the wheel 122 of the container 1 can be removed efficiently, after carrying out the container 1 from the carrying-out exit 5, the trace by a water | moisture content remains on the path | route which the wheel 122 of the container 1 traveled. Can be suppressed.

  Then, the portion of the container 1 that is easy to remove is dried at a high speed when it is removed by drying, and the portion that is difficult to remove from the container 1 is moved at a low speed, decelerated, and stopped when it is removed. While shortening the time required for drying, it is possible to surely remove the drops. That is, the water adhering to the container 1 can be efficiently removed.

(Embodiment 2)
Next, as a second embodiment of the container processing apparatus P, a container drop dryer H will be described in detail with reference to FIGS. In the description of the second embodiment, only the characteristic part of the second embodiment will be described to simplify the description, and a part of the description of the same part as the first embodiment will be omitted. Further, the same configuration as that of the first embodiment will be described using the same reference numerals. The container drop removing dryer H of the second embodiment is different from the container cleaning drop removing dryer W of the first embodiment in that it does not include a cleaning zone.

  Similarly to the container 1 of the first embodiment, the container 1 needs to be washed and dedried and dried in preparation for delivery the next day after being returned to the feeding center C. After such manual cleaning with the container 1 as an object to be cleaned and after cleaning with a cleaning machine, the container drop removing dryer H removes and dries the container 1.

(Container drop dryer)
As shown in FIG. 25 and FIG. 26, the container drop drying machine H includes a drop removal drying zone 3 that is formed in a long tunnel shape in the transport direction for transporting the container 1 and that drops and dries the cleaned container 1. . Further, the container drop dryer D is provided with an inlet 4 for carrying the container 1 on the upstream side of the drop removal drying zone 3 in the transport direction of the container 1, and an outlet 5 for carrying out the container 1 is provided for the drop removal drying zone 3. The container 1 is provided on the downstream side in the transport direction. Therefore, in the container removal drier H, the container 1 is carried in from the carry-in port 4, passes through the drop removal drying zone 3, and is carried out from the carry-out port 5.

  Similarly to the container cleaning / dropping dryer W of the first embodiment, the container dropping / drying dryer H is provided with an exhaust port E on the ceiling near the carry-in port 4. The exhaust port E takes in air from the carry-out port 5 and discharges the air that has passed through the drop removal drying zone 3 of the container drop dryer D to the outside of the facility where the container drop dryer H is installed (FIG. 26). See arrow a).

  As shown in FIG. 25, in the container drop dryer D, a carry-in rail 6 for guiding the container 1 to the carry-in port 4 is provided at the carry-in port 4 as in the container cleaning drip-dryer W in the first embodiment. The carry-out port 5 is provided with a carry-out rail (not shown) for guiding the container 1 from the carry-out port 5. When carrying in the container 1, the wheel 122 of the container 1 is carried on the carry-in rail 6.

  As shown in FIGS. 26 and 27, the container drop dryer H accommodates a part of the lower side of the container drop dryer H in a pit (accommodating space) S dug in the floor. Thereby, since the conveyance rail 72 can be arrange | positioned in the substantially same height as the floor surface FL, the container 1 can be carried in the container dewatering dryer H substantially horizontally. In the present embodiment, the pit S is dug from the floor surface FL to a predetermined depth, for example, about 250 mm. The container drip dryer H is formed in a tunnel shape so that the upper outer body HU is above the floor FL and the lower outer body HD is below, and the upper outer body HU has a substantially rectangular cross section. Has been.

  The container drip dryer H includes the transport mechanism 7 similar to the container cleaning drip dryer W of the first embodiment, and the wheels 122 of the container 1 are placed on the transport rail 72 to engage the claw of the top chain 71. 73 is engaged with the bar 124 of the container 1 to convey the container 1. The transport rail 72 is provided at substantially the same height as the floor surface FL. Further, the feed side and the return side of the top chain 71 are disposed so as to be higher than the floor surface FL. In the present embodiment, the engaging claw 73 on the return side of the top chain 71 has a vertex that is substantially the same height as the floor surface FL. Therefore, in the present embodiment, the entire top chain 71 is disposed so as to be above the floor surface FL. The utility space 70 can be used as a scaffold for cleaning and maintenance in the container drop dryer D.

  As shown in FIGS. 25 to 27, the drop removal drying zone 3 is provided with blowers 401 to 407, heat exchangers 501 to 503, and drop removal drying means 301 to 310 similar to the container washing drop removal dryer W, The container 1 carried into the container drop dryer H after washing is drop-dried.

(Drip removal drying zone)
As shown in FIG. 27, similarly to the container cleaning drop removal dryer W of Embodiment 1, the drop removal drying zone 3 includes a plurality of drop removal drying areas in the conveyance direction of the container 1. A preliminary drop removal drying area 30, an upper drop removal drying area 31, a middle drop removal drying area 32, and a lower drop removal drying area 33 are provided in this order from the carry-in port 4 side. On the downstream side in the transport direction of the container 1 in the lower droplet removal drying area 33, the carry-out port 5 continues.

  Each drop removal drying area 30-33 is provided with drop removal drying means 301-310 like the container washing | cleaning drop removal dryer W of Embodiment 1, and each droplet removal drying means is container washing droplet removal of Embodiment 1. As with the dryer W, a wide area air nozzle 340 and straight air nozzles 311 to 330 are provided.

  Similarly to the container washing / dropping dryer W, the lower droplet removing / drying area 33 of the container dropping / drying machine H is provided with a drop removing / drying means 309 that jets air from below toward the bottom 12 of the container 1. The droplet removal drying means 309 is connected from the blower 407 via the air pipe 370. A part of the air pipe 370 is disposed at a position lower than the floor surface FL, and is connected to the straight air nozzle 327 of the droplet removal drying means 309.

  Thereby, a space for installing the air pipe 370 can be widened, and the path of the air pipe 370 can be configured so that the air flowing through the air pipe 370 can flow as smoothly as possible. it can. Therefore, air having a temperature lower than the predetermined temperature can be ejected from the droplet removal drying means 309 without greatly damaging the wind pressure of the air to be ejected and without disturbing the flow.

(Operation and effect of container processing equipment)
In the container processing apparatus P according to the first and second embodiments as described above, the transport rail 72 of the transport mechanism 7 has substantially the same height as the floor surface FL, and extends substantially horizontally from the carry-in port 4 to the carry-out port 5. Provide as follows. Thereby, since the container 1 can be advanced to a substantially horizontal direction and can be mounted in the conveyance rail 72, the container 1 can be carried in smoothly and the container 1 can be carried out smoothly. Accordingly, the container 1 can be carried in, transported and carried out substantially horizontally by one transport mechanism.

  Further, the transport mechanism 7 transports the wheels 122 of the casters 121 while rolling on the transport rails 72 while pressing the bars 124 of the container 1 with the engaging claws 73. Thereby, compared with the system which mounts the wheel 122 on the top chain 71 and conveys the container 1, in this invention, the load concerning the conveyance mechanism 7 can be made small.

  In addition, the top chain 71 is circulated and driven by a drive sprocket 74 and a driven sprocket 77, but since the pitch diameter of the sprocket used for the top chain is generally small, the top chain 71 is attached to the transport mechanism 7. By using it, the vertical dimension of the transport mechanism 7 can be reduced. Then, by reducing the vertical dimension of the transport mechanism 7, even if the transport mechanism 7 is provided below the bottom 12 of the container 1 to be transported, the transport mechanism 7 does not enter the pit S deeply. Thereby, the pit S can be made shallow.

  Further, since the pressing surface 731 of the engaging claw 73 rises at a predetermined angle, for example, 90 degrees, the bar 124 can be reliably engaged with the engaging claw 73 without escaping. Note that while the container 1 is being transported with the predetermined angle of the pressing surface 731 being, for example, 70 degrees to 80 degrees, a force exceeding the expected direction in the direction opposite to the transport direction of the container 1 should be The bar 124 may be released from the engaging claw 73 when it is added.

  By doing so, when the container 1 is no longer transported in the transport direction for an unexpected reason, the bar 124 rolls upward on the pressing surface of the engaging claw 73, and the bar 124 moves the engaging claw 73 to the container. It is possible to stop the conveyance of the container 1 by overcoming in the direction opposite to the conveyance direction 1 and to protect the conveyance mechanism 7 and the container 1 that is the object to be conveyed.

  In that case, a sensor that detects that the container 1 has stopped without being transported in the transport direction is installed in the container processing apparatus P so as not to collide with the subsequent container 1, and a signal is transmitted from the sensor to the control panel G. Thus, the operation of the container processing apparatus P may be stopped together with a warning sound. Thereby, when the force beyond assumption is applied in the direction opposite to the conveyance direction of the container 1, the conveyance mechanism 7 can be protected, and the container 1 in which the bar 124 has escaped from the engaging claw 73 is moved to the subsequent position. A collision with the container 1 can be prevented. And in order to discover the cause which the container processing apparatus P stopped, it can check immediately.

  The driving speed and driving time of the top chain 71 at low speed driving and high speed driving are processed by the predetermined interval of the engaging claw 73 and the container processing device P per time (cleaning and droplet removal drying, or droplet removal drying). ) Can be set optimally according to the ability.

  Further, since the bar 124 can be moved in the vertical direction in the long hole 125 having the support portion 123, the height relationship between the bar 124 and the conveying surface 76 of the top chain 71 and the engaging claw 73 is made constant. Can keep. Thereby, for example, even if the wheel 122 of the container 1 is worn down and the height of the bar 124 supported by the support portion 123 of the container 1 is changed, the bar 124 is placed on the transport surface 76 of the top chain 71, It can be conveyed by the engaging claw 73.

  Further, even when the height from the floor surface FL to the lower surface of the bottom 12 of the container 1 is different, the bar 124 can move up and down within a range necessary for engaging with the engaging claw 73. This enables the container 1 to be transported by engaging the bar 124 with the engaging claw 73 regardless of the height of the container 1 up to the lower surface of the bottom 12. Therefore, the height of the top chain 71 of the container processing apparatus P can be adjusted even if the container 1 has a different height from the floor surface FL to the lower surface of the bottom 12 of the container 1 for each container 1. First, the container 1 can be carried in, conveyed, and carried out by moving the bar 124 of the container 1 up and down.

  Furthermore, the engaging claw 73 may be of a height that can be engaged with the bar 124, and the bar 124 can be moved up and down in the long hole 125 and kept on the conveying surface 76. The height of the engaging claw 73 from the conveyance surface 76 can be adjusted to the minimum. By minimizing the height of the engaging claw 73, the height of the transport mechanism 7 can be lowered, and the pit S can be made shallower.

  In the container 1 transported by the transport mechanism 7, the adhering moisture is sequentially removed from the upper drop removal drying area 31, the middle drop removal drying area 32, the lower drop removal drying area 33, and the upper part 101 of the container to the middle part 102 and the lower part 103. It can be blown off by wind pressure to remove the droplets and dried by heat. Thereby, since it can remove and dry according to the motion which a water | moisture falls, the water | moisture content adhering to the container 1 can be removed effectively.

  In addition, when the container 1 is located in each of the drop removal drying regions 30 to 33 by the partition plate 35, air at a predetermined temperature for removing the droplets of the container 1 is retained in each region, The drying of the container 1 can be promoted by the temperature.

  When the container 1 is moved from the droplet removal drying region by the conveyance of the container 1, the partition of the droplet removal drying region formed by the partition plate 35 and the container 1 is removed, and the container 1 is removed and dried at a high temperature. The humid air can be exhausted from the container processing apparatus P to the outside by being put on the flow of air exhausted from the upper exhaust port E on the carry-in port 4 side of the container 1.

  The droplet removal drying means 301 to 310 are constituted by straight-ahead air nozzles 311 to 330 and a wide area air nozzle 340 that inject air. However, the droplet removing and drying means is not limited to the air nozzle as long as it can remove and dry the water adhering to the container 1, and may have other configurations. For example, water adhering to the container 1 may be removed with a water-absorbing material such as a sponge, or a member such as a scraper, and dried by heating with infrared radiation.

  As an embodiment of the container processing apparatus P, the container cleaning / deleting / drying machine W that cleans and drip-drying the container 1 and the container-deletion / drying machine H that performs drop-drying the container 1 have been described. However, the container processing apparatus P may be a container cleaning machine that only cleans containers. Such a container cleaning machine includes, for example, a cleaning zone 2 of the container cleaning / dropping / drying machine W, an inlet 4 on the upstream side in the transport direction of the container 1, and an outlet 5 on the downstream side. In addition to these, if the container processing apparatus P performs processing while transporting the container 1, processing other than cleaning and droplet removal drying, for example, high-temperature steam, alcohol or hypochlorous acid aqueous solution is used. The container 1 may be sprayed to disinfect the container 1, or the container 1 may be sprayed with a chemical to perform surface treatment of the container 1.

  In addition, the container 1 processed by the container processing apparatus P is formed with the upper and lower shelves 18 and 19 of the storage unit 17 mainly composed of cylindrical pipes. Thereby, even if washing water adheres, a cylindrical pipe can flow down easily and can make it easy to remove the moisture adhering to the container 1. Further, the end 126 of the member forming the bottom 12 of the container 1 is folded downward. The lower end of the end portion 126 faces downward so that moisture attached to the container 1 can easily flow down. Thereby, it is possible to easily remove the moisture attached to the container 1.

  In addition, the container processing apparatus P accommodates a part of the lower side in the pit S dug in the floor of the facility. When the legs F are installed on the bottom surface of the pit S, a sufficient predetermined space, for example, a 150 mm space is formed between the lower surface of the container processing apparatus P and the bottom surface of the pit S so as to be cleaned with a mop or the like. It is common to do.

  In addition, when the legs F are installed on the floor surface FL, it is necessary to form a sufficient predetermined space between the lower surface of the container processing apparatus P and the floor surface FL, for example, the carry-in rail 6 and the carry-out rail 6 It is necessary to make the rail 8 into a slope shape, or to install a lifter in place of the carry-in rail 6 and the carry-out rail 8 to move the container 1 up and down, and carry the container 1 into and out of the container processing apparatus P. The work efficiency is reduced.

  Therefore, the pit S is dug in the floor, and the legs F are installed on the bottom surface of the pit S to form a sufficient predetermined space between the lower surface of the container processing apparatus P and the bottom surface of the pit S, and the container 1 It is preferable to make the carry-in rail 6, the transfer rail 72, and the carry-out rail 8 substantially horizontal so as to improve the work efficiency of the carry-in and carry-out.

  However, the configurations shown in the above embodiments are specific examples of the components, and the configurations, shapes, or attachment modes are limited to those shown as the embodiments unless departing from the gist of the present invention. Various modifications or changes are possible.

  The present invention can be applied to a container processing apparatus that performs various processes while transporting a container.
