[0002]
[Prior art]
As a conventional moving tank system, for example, one described in JP-A-8-40544 is known. This moving tank system is a production system for producing a small amount of fluid composites in a variety of products. As shown in FIG. 7, the rail 3, the stations 6a to 6j provided on at least one side of the rail 3, and the rail 3 are provided. The moving tank 5 travels along the rail 3 while being suspended by the cart 1, and is moved to a predetermined station 6c, 6d, 6e, 6g, 6h, 6i, 6j, etc. The transfer tank 5 is handed over, and then the transfer tank 5 suspended and held at the stations 6c, 6d, 6e, 6g, 6h, 6i, 6j, etc. and subjected to a predetermined work is received by the carriage 1, and this transfer tank 5 is sequentially moved to stations 6c, 6d, 6e, 6g, 6h, 6i, 6j and the like. The rail 3 is provided along the floor portion 101 of the building, and both the first floor and the second floor can be used as a work space and a space for arranging auxiliary equipment.
[0003]
The moving tank 5 located in each station 6c, 6d, 6e, 6g, 6h, 6i, 6j, etc. receives operations such as receiving raw materials, stirring the contents, discharging the products in the moving tank 5, and washing. The moving tanks 5a, 5b, etc., loaded with the finished product are put on standby at predetermined stations 6a, 6b, 6f, etc. while waiting for payout for inspection and shipment. For example, in the case of a moving tank system for a paint plant, it may take several days as a waiting period in order to actually paint and inspect whether the product paint has the correct color and performance. Therefore, the conventional moving tank system has been dealt with by providing a plurality of stations 6a, 6b, 6f and the like for standby.
[0004]
According to this type of moving tank system, the moving tank 5 is suspended from the carriage 1 and the carriage 1 travels on the rail 3 along the floor 101 on the second floor, which is hindered by other equipment such as piping. It is easy to move the moving tank 5 and the process is not divided over the entire hierarchy as in the method using a stacker crane. The moving tank 5 is not limited to the stations 6c, 6d, 6e, 6g. , 6h, 6i, 6j, etc. are suspended and held to receive the work, so that the simultaneous operation from the upper and lower floors to the moving tank 5 is easy. Moreover, since the moving tank 5 does not move directly on the floor portion of the first floor, the floor portion of the first floor can be used effectively for incidental facilities. In addition, it is a method that is not easily restricted by the mixed work of the moving tanks 5 having different capacities, the work floor height, and the like. In addition, instead of running on the rail 3, the cart 1 holding the moving tank 5 may run on another track, or may be caused to run on a non-track of the floor 101 with air pressure. Yes.
[0005]
[Problems to be solved by the invention]

For this reason, all the above-mentioned devices are constituted by explosion-proof structures.
[0020]
Next, the operation will be described.
Operations such as receiving of raw materials, stirring of contents, dispensing of products, and washing are given to the moving tank 5 moved to each work station 6b to 6j in the production system. The transport carriage 1 receives the moving tank 5 that has finished the work in the predetermined stations 6b to 6j, and holds it suspended. The transport cart 1 that holds the moving tank 5 suspendedly travels along the rail 3, stops in front of the next stations 6b to 6j, and delivers the moving tank 5 to the stations 6b to 6j. When the transfer tank 5 is exchanged between the transfer carriage 1 and each of the stations 6b to 6j, each driving device 31 and 35 is driven, and the transfer tank 5 suspended and held by the transfer carriage 1 is set to a predetermined station 6b. To 6j to receive a new work, and to allow the transport tank 1 to receive the moving tank 5 after the work in the predetermined stations 6b to 6j is completed.
[0021]
The moving tank 5a loaded with the finished product after receiving the predetermined work is placed on the transport carriage 1 and transported to the take-out station 6a. The moving tank 5a, which is driven to the take-out station 6a by driving the driving devices 31 and 35, locks the suspension 11 manually with the placement lid 51 placed thereon to prevent the entry of dust. Then, it is lifted by the electric hoist 71. The electric hoist 71 that lifts the moving tank 5a is driven to travel by the traveling device 70, and is carried out of the production system defined by the openings 102a and 102b.
[0022]
First, the electric hoist 71 is caused to travel to the right in FIG. 2 along the hoist rail 72 by the traveling device 70, and the electric hoist 71 is brought into contact with the traveling stopper 8a and stopped. Thereafter, the hanger 11 moved to above the take-out station 6a is lowered and locked to the locking portion 54 of the moving tank 5a. At that time, the door 12a of the safety fence 12 is opened. Next, the electric hoist 71 is driven to drive the hanger 11 and the moving tank 5a up to a predetermined height position, and the electric hoist 71 is caused to travel along the hoist rail 72 by the traveling device 70. Is brought into contact with the travel stopper 8b and stopped. Thereby, as shown in FIG. 2, the moving tank 5a will be in the state received from the open one side surface of the moving tank installation stand 9a placed in the predetermined position. Next, the suspended moving tank 5a is lowered, and the moving tank 5a is held on the moving tank installation base 9a that has been moved in advance to an appropriate position on the floor surface FL. By accepting the moving tank 5a from one side of the opening of the moving tank installation stand 9, the moving tank 5a can be transferred from the take-out station 6a to the moving tank installation stand 9a with a relatively low position.
[0023]
If the moving tank 5a is held on the moving tank installation base 9a, the lifting tool 11 is removed from the locking portion 54 of the moving tank 5a, and the air bearing device 10 is inserted into the space 90 of the moving tank installation base 9a and moved. The moving tank installation base 9 a that holds the tank 5 a suspended is moved to the standby space 101 a while being levitated by the air bearing device 10. Each moving tank installation base 9 has a structure in which the air bearing device 10 can be inserted into the space portion 90 below the hoist rail 72 from a direction perpendicular to the space portion 90 and is excellent in workability. In this way, the moving tank 5a full of finished products is moved to the standby space 101a while being placed on the moving tank installation base 9a, and waits in the standby space 101a while waiting for inspection and delivery. As mentioned above, in the case of a moving tank system for paint plants, it takes several days as a waiting period to actually check whether the product paint has the correct color and performance. is there.
[0024]
If the moving tank 5a full of completed products moves to the standby space 101a, the air bearing device 10 is extracted from the moving tank installation base 9a. Since a plurality of mobile tank installation platforms 9a to 9e can be made to stand by in the standby space 101a, if a plurality of mobile tank installation platforms 9a to 9e are prepared, a plurality of mobile tanks 5 can be produced as necessary. Can be taken out of. As a result, each station 6b-6j in the production system can be effectively used for production work. The moving tank 5, which has been required to be taken out from the standby space 101a, such as paid out for shipment after the inspection is completed, is moved from the standby space 101a to a desired location. Thus, the moving tank 5 can be taken in and out freely in the standby space 101a. Further, the moving tank 5 containing the product determined to be defective as a result of the inspection is moved again from the standby space 101a to the take-out station 6a by the reverse procedure, and any of the work stations 6b to 6 is operated. It is also possible to receive another work in 6j. Of course, it is also possible to give work to the moving tank 5a located at the take-out station 6a. It is also possible to omit the air bearing device 10 and lift the moving tank installation bases 9a to 9e on which the moving tank 5 is mounted with a powered forklift (not shown) to move to the standby space 101a.
[0025]
FIG. 5 shows a structural example in which a self-propelled mobile carriage 14 is used as a base instead of the mobile tank installation bases 9 a to 9 e and the air bearing device 10. The movable carriage 14 can run on rails 15 laid on the floor surface FL, and two movable tanks 5 can be mounted on each movable carriage 14. The moving tank 5 is held by holding the holding frame 52 of the moving tank 5 on the upper surface of the moving carriage 14 in the same manner as the moving tank installation stands 9a to 9e. A plurality of mobile tanks 5 mounted in the standby space 101a secured on both sides in the extending direction of the rail 15 by laying the rail 15 so as to intersect with the traveling path (the hoist rail 72) of the electric hoist 71 in plan view. Can be made to stand by. The mobile carriage 14 may be a manual type instead of the self-propelled type, or may be a type that pulls forward and reverse with a wire or the like from the outside. Further, the rail 15 can be omitted, and the movable carriage 14 can be constituted by a trackless carriage.
[0026]
FIG. 6 shows a structural example in which the gantry 16 is used in place of the movable tank installation gantry 9 a to 9 e and the air bearing device 10. The gantry 16 includes four casters 40 at the lower portion, and the casters 40 can run while rolling on the floor surface FL. The moving tank 5 is held by holding the holding frame 52 of the moving tank 5 on the upper surface of the mount 16 in the same manner as the moving tank installation stands 9a to 9e. The gantry 16 on which the moving tank 5 is mounted is pushed and pulled by a gantry pusher, a small electric forklift, etc., not shown, and moved to the standby space 101a. If the gantry 16 is used, it is not necessary to lift the entire gantry 16 (total weight is usually 1 to 10 tons) on which the moving tank 5 is mounted, and the gantry 16 can be moved by a small electric hawk lift.
[0027]
By the way, in the above embodiment, the rail 3 is disposed above the main opening 102a communicating with the first and second floors, and the stations 6a to 6j are formed on both sides of the rail 3, but the rail 3 It is also possible to form the stations 6a to 6j only on one side. Further, although a single take-out station 6a and a plurality of stations 6b to 6j that receive only work are provided, it is also possible to provide a plurality of take-out stations 6a to which the hoisting device 7 with traveling device is attached. Furthermore, the rail 3 is omitted, and not only the method in which the transport carriage 1 travels on other tracks, but also the method in which the carriage on the trackless surface is lifted from the floor surface by air pressure to transport the moving tank. The tank system can be applied as well.
[0028]
【The invention's effect】
As understood from the above description, the moving tank system with a standby device according to the present invention can provide the following effects.
That is, at least one of the stations in the mobile tank system is a take-out station provided with a function for taking out the mobile tank, and the mobile tank taken out of the station has a main opening and a station opening that function as a production system. It was moved to a standby space provided outside the factory, where it was decided to wait for inspection and shipment, and a large number of standby stations were avoided in the production system.
[0029]
Therefore, the mobile tank can be kept out of the production system for a long time without hindering work on the mobile tank, and the number of complicated and expensive stations of the mobile tank system can be reduced. In addition, the moving tank can be arranged close to the standby space, and the moving tank can be efficiently standby in a small occupied space, so that the space can be effectively used.
