Hereinafter, an automatic filling device 1 for filling a can container according to an embodiment of the present invention will be described with reference to the drawings.
As shown in FIG. 1, the equipment including the automatic filling device 1 is provided with a pool conveyor 4, and the pool conveyor 4 has, for example, a number of drum cans 6 that can be filled with an amount of filling for half a day or one day. Prepared in advance. The drum can 6 is an example of a can container and is an open can having a detachable canopy 6 a, and an operator lifts it with a lifter 8 and places it on the pool conveyor 4.

  The automatic filling device 1 includes a can conveyance conveyor 10, a lid conveyance conveyor 12, a lid removal device 14 (see FIG. 2), a bag feeding device 16, a sealing device 18, a filling material supply device 20, and an inner bag 2 pushing device 22 ( ) And the like. The can conveyance conveyor 10 forms a can conveyance path for conveying the opened drum can 6 from which the drum can 6 and the canopy 6a are removed. The lid transport conveyor 12 forms a lid transport path different from the can transport path for transporting the canopy 6a.

The lid removing device 14 is provided in the vicinity of the start area of the lid conveying path. A large number of drums 6 placed on the pool conveyor 4 are conveyed one by one by the can conveyance conveyor 10 to the lid removing device 14. The can conveyor 10 is, for example, a roller conveyor, and the lid conveyor 12 is, for example, a hanger conveyor.
As shown in FIG. 2, the lid removing device 14 includes a suction rod 24 that extends vertically, a lifting cylinder 26 that lifts and lowers the suction rod 24, and an advancing and retracting cylinder 28 that slides the suction rod 24 and lifting cylinder 26 horizontally. It has.

  A suction cup 24 a is provided at the lower end of the suction rod 24. The elevating cylinder 26 lowers the suction rod 24 on the canopy 6a, sucks the canopy 6a with the suction cup 24a, lifts the suction rod 24, lifts the canopy 6a, and removes it from the drum can 6. The advancing / retreating cylinder 28 moves the suction rod 24 that has attracted the canopy 6a onto the table 30 removed from the can conveyor 10, and the canopy 6a is temporarily placed on the table 30 by releasing the suction by the suction cup 24a. The

  As shown in FIG. 3, the lid conveyor 12 includes a horizontally extending gripping arm 32, a driving unit 34 that opens and closes the gripping arm 32, and a lifting cylinder 36 that lifts and lowers the gripping arm 32 and the driving unit 34. And a transport roller 38 for moving the main body of the cover transport conveyor 12 along a cover transport path which is a hanging rail. The elevating cylinder 36 lowers the grip arm 32, and the drive unit 34 grips and grips the canopy 6 a on the table 30 by closing the grip arm 32. The canopy 6a is conveyed on the lid conveyance path while being held by the holding arm 32 and suspended. The lid transport conveyor 12 may include a suction rod similar to that of the lid removing device 14. Further, the lid conveyor 12 may be a roller conveyor or the like.

  On the other hand, the drum can 6 from which the canopy 6 a has been removed is transported by the can transport conveyor 10, and the inner bag 2 is automatically loaded into the drum can 6 by the bag feeder 16. The inner bag 2 is manufactured from a flexible synthetic resin film. This film has a thickness of about 100 μm to 200 μm, for example, and acquires the functions of the inner bag 2 (corrosion resistance, deodorization, moisture resistance, oxygen permeability, etc.) required according to the type of filling. Therefore, it is formed by laminating resins such as polyethylene, polypropylene, polyester and polyamide. The inner surface of the film is made of at least a heat-bondable resin that can be made by heat-sealing.

  As shown in FIG. 4, the bag supply device 16 includes an inner bag magazine 40, a pair of bag supply arms 42, and a lifter 44 (see FIG. 1) that raises and lowers the drum can. The inner bag magazine 40 is formed by stacking a large number of racks 40a (for example, about 50 stages) vertically. In each rack 40a, the folded inner bag 2 is horizontally accommodated one by one with its mouth portion 2a facing the can conveyor 10 side. Moreover, the concave notch part is formed in the both sides of each rack 40a. Each notch part exposes a part of both sides near the mouth part 2a of the inner bag 2 from the rack 40a.

  Each bag supply arm 42 is formed of a plate having a substantially U-shape when viewed from the conveyance direction X of the can conveyance conveyor 10. Between the inner bag magazine 40 and the can conveyor 10, a rotation shaft 46 extends along the conveyance direction X, and one end of each bag supply arm 42 is coupled to the rotation shaft 46. At the other end of each bag supply arm 42, side support chucks 42a are formed for gripping both sides of the inner bag 2 near the mouth 2a. When the rotation shaft 46 is rotated by the operation of the bag supply device 16, the bag supply arm 42 swings from the inner bag magazine 40 side toward the can conveyance conveyor 10 side.

  At this time, each side support chuck 42a passes through both notches of one rack 40a of the inner bag magazine 40, and grips and pulls out both sides on the mouth 2a side of the inner bag 2 exposed from both notches. . When the swing of the bag supply arm 42 is stopped, the inner bag 2 is supported in a suspended posture with the mouth portion 2a up by the side support chuck 42a. During operation of the bag feeder 16, the drum can 6 conveyed by the can conveyor 10 is temporarily stopped in front of the bag feeder 16, and the suspended inner bag 2 is positioned and set immediately above the drum can 6. .

  Next, preparation for supply of the filling material from the supply device 20 to the inner bag 2 is performed by the sealing device 18. When one inner bag 2 is pulled out from the inner bag magazine 40, the inner bag magazine 40 is raised by the height of one rack 40a by a step motor or the like (not shown). As a result, the inner bag 2 can be automatically loaded into the next drum can 6 after the inner bag 2 has been loaded into one drum can 6 and, after completion of the filling. For example, if a predetermined amount of the inner bag 2 is set in the inner bag magazine 40 in advance, the bag supply can be automated over a long period of time.

  As shown in FIGS. 5A to 5C, the sealing device 18 includes a pair of an upper end support chuck 48, a tension chuck 50, an opening bar 90, a jacket 52, a sealing bar 54, a pressing bar 56, and a seal. The bar 58 includes the chucks 48 and 50 and the advance and retreat cylinders for driving the bars 90, 54, 56 and 58, respectively. Each of the chucks 48 and 50 and the bars 54, 56, and 58 is formed of a pair of opposing bar-shaped members. The chucks 48 and 50 and the bars 54, 56 and 58 operate in a direction in which the rod-shaped members are pressed against each other with the respective forward and backward cylinders sandwiching the upper end portion of the inner bag 2, and the opening bar 90 is the opening of the inner bag 2. Acting in the direction of expanding the part 2a, the inner bag 2 is supported at different height levels.

  The sealing device 18 is disposed on the inner bag 2 supported in a hanging posture. The sealing device 18 is configured to be movable up and down as a whole. After the bag supply device 16 completes the loading of the inner bag 2 into the drum can 6, the entire sealing device 18 is first lowered. Next, the upper end support chuck 48 grips the upper end portion of the inner bag 2, and instead, the side support chuck 42 a of the bag feeding arm 42 is retracted to carry the inner bag 2, and then the entire sealing device 18 is moved. Is raised.

When the raising of the sealing device 18 is completed, the bag supply arm 42 swings and is retracted to the inner bag magazine 40 side. Next, the inner bag 2 is moved from the upper end support chuck 48 to the tension chuck 50. The tension chuck 50 grips the upper end portion of the inner bag 2.
As shown in FIG. 6, in the opening bar 90, a plurality (three in FIG. 6) of suction pads 60 are arranged on the gripping surface 90a of the opposing bar-shaped member.

Each rod-like member of the tension chuck 50 is attached to the main body of the sealing device 18 via a spring (not shown). Then, with the suction pad 60 adsorbing the upper end of the inner bag 2, the rod-shaped members are separated from each other, and the mouth portion 2a of the inner bag 2 in the folded state is opened.
The spring is for reducing the tension of the inner bag 2 by the tension chuck 50 when the opening bars 90 are separated from each other and making it easy to open the mouth portion 2a of the inner bag 2.

  Next, as shown in FIG. 7, the jacket 52 is lowered toward the opened mouth 2 a and inserted into the inner bag 2. The jacket 52 is a tube having pointed convex portions 66 on both the left and right sides. As shown in FIG. 5, the jacket 52 has an air supply port 64b and an air intake port 64c communicating with the outside. The inner bag 2 with the jacket 52 inserted is pressed against the inner bag by the sealing bar 54 and held between the convex portions 66. Thereafter, the tension chuck 50 opens the inner bag 2.

  Next, the filling nozzle 62 of the supply device 20 is inserted into the inner bag 2 through the nozzle port 64 a of the jacket 52. Next, the sealing bar 96A is advanced by the sealing cylinder 95A, and the filling nozzle 62 is gripped by the sealing bar 96A. Thereby, the filling nozzle 62 is kept airtight with the jacket 52, and the sealing performance between the filling nozzle 62 and the jacket 52 is ensured. Next, a small amount of filling gas such as air or nitrogen is sent from the air supply port 64b of the jacket 52 to perform gas preliminary supply (gas preliminary supply means). By performing this preliminary gas supply, the inner bag 2 is slightly inflated while maintaining the folded state, and the hanging inner bag 2 is reliably positioned in a substantially vertical position directly above the center of the drum can 6.

  Next, the drum can 6 is raised by the lifter 44 (see FIG. 1) provided on the can conveyance conveyor 10, and most of the inner bag 2 except the upper end is positioned inside the drum can 6. Next, the inner bag 2 is further inflated and is brought into close contact with the inner surface of the drum can 6 by further supplying a filling gas from the air supply port 64 b of the jacket 52 and supplying the main gas. Next, the filling material supply device 20 is operated to supply the filling material to the inner bag 2.

  As shown in FIG. 1, the supply device 20 is disposed on the upper side of the sealing device 18 and includes a hopper 68, a dust collecting device 70, a cutting device 72, a weighing device 74, a filling nozzle 62, and the like in order from the top. The hopper 68 is provided with an inlet 68a through which a filler is introduced, a water inlet 68b, an air inlet 68c of a gas such as nitrogen, and the like. The cutting device 72 is, for example, a screw conveyor or the like that cuts out a predetermined amount of the filling material in the hopper 68 and conveys it to the weighing device 74. The dust collector 70 is connected to the intake port 64 c of the jacket 52 and collects dust to deaerate the inside of the inner bag 2. The collected dust is peeled off from a filter provided in the dust collector 70 by vibration, for example, passes through the cutting device 72, and is filled in the inner bag 2 again.

  Here, the filler in the inner bag 2 is, for example, incinerated ash, pellets, powder, or the like, or a solid or liquid having a corrosive action or odor such as moisture. The inner bag 2 avoids direct contact of the filling material with the inner surface of the drum can 6, thereby suppressing corrosion of the drum can 6 due to the filling material and enabling stable storage of the filling material and the drum can 6 over a long period of time. . In addition, the inner bag 2 after the filling is filled is sealed by heat sealing with a seal bar 58 to be described later, thereby blocking the filling from the outside air, spreading the odor from the filling, decaying the filling, and filling. Suppresses oxidation and the like.

  The metering device 74 includes a meter such as a load cell (not shown) and a gate valve 74a. The metering device 74 is connected to the filling nozzle 62 via a gate valve 74a. The weighing device 74 stops the cutting device 72 when the weight of the filling material measured by the weighing device reaches a specified amount, and the cutting of the filling material from the hopper 68 is completed. Next, by opening the gate valve 74a, the filling material passes through the filling nozzle 62 and is put into the inner bag 2, and then the gate valve 74a is closed.

  When the first filling of the filling material into the inner bag 2 is completed, the drum can is slightly raised by the lifter 44. This prevents the inner bag from being broken by the weight of the filling material filled in the inner bag 2. Next, the above-described series of steps from cutting out the filling to opening the gate valve 74a is repeated several times, and a predetermined amount of filling is divided into several times to fill the inner bag 2, and filling the inner bag 2 Complete filling. After the filling is completed, the pressure contact of the filling nozzle 62 by the sealing bar 96A is released, and the filling nozzle 62 can be pulled out.

  Next, the sealing device 18 and the drum 6 are lowered to a predetermined position. At this time, the filling nozzle 62 is pulled out from the nozzle port 64a of the jacket 52, and the sealing bar 96B is pressed against the inner bag after the filling nozzle 62 is pulled out. Hold 2 seals. Next, the inside of the inner bag 2 is deaerated by sucking air or a gas such as nitrogen from the air inlet 64b of the jacket 52, and an extra space occupied by other than the filler in the inner bag 2 is eliminated (a deaeration means). ).

Next, as shown in FIG. 8, in the sealing device 18, after the upper end portion of the inner bag 2 positioned below the lower end portion of the jacket 52 is pressed and held by the pressing bar 56, the sealing bar 96 </ b> B is retracted and the jacket 52 Is pulled out from the inner bag 2.
Next, as shown in FIG. 9, the seal bar 58 sandwiches the upper end portion of the inner bag 2 above the pressing bar 56. The seal bar 58 is a so-called heat sealer, and the upper end portion of the inner bag 2 is heat-sealed by heat sealing by the seal bar 58, and the mouth portion 2a of the inner bag 2 is closed. The length in the longitudinal direction of the seal bar 58 is defined in advance so as to be at least smaller than the inner diameter of the drum can 6 so that the seal bar 58 can be lowered and used without contact with the drum can 6. Next, the seal bar 58 and the pressing bar 56 are retracted, and the drum can 6 is lowered to the can conveyance conveyor 10 by the lifter 44. Then, the drum can 6 is transported to the pushing device 22 by the can transport conveyor 10.

  As shown in FIG. 10, the pushing device 22 includes a disk-shaped pressing plate 76, a motor 78 that rotates the pressing plate 76, and a lifting cylinder 80 that moves the pressing plate 76 and the motor 78 up and down. The pressing plate 76 descends to the inside of the upper end portion of the drum can 6 while rotating by the operation of the motor 78 and the lifting cylinder 80. At this time, the upper end portion of the inner bag 2 protruding from the upper portion of the drum can 6 is pushed into the drum can 6 and stored. Next, the drum can 6 is transported by the can transport conveyor 10 to a region where the lid transport conveyor 12 is directly above.

  The lid transport conveyor 12 lowers the grip arm 32 by the lift cylinder 36 and opens the grip arm 32 by the drive unit 34 to release the grip of the canopy 6 a and mounts it on the drum can 6. That is, the lid transport conveyor 12 is also used as a lid attaching device for the drum can 6. Although not shown, a lid attaching device separate from the lid conveyor 12 may be provided.

  Next, as shown in FIG. 1, data necessary for managing the drum can 6 is printed on the top of the canopy 6 a of the drum can 6 to which the canopy 6 a is attached, and then the drum can 6 is moved by the palletizer 84. It is placed on the pallet 86 and carried out of the facility by a forklift 88. In addition, you may use other moving means, such as a conveyor other than the forklift 88, for carrying out the drum can 6 from the said equipment. Further, when the canopy 6a must be attached to the drum can 6 immediately after filling with the filling material, an automatic lid closing machine (not shown) may be introduced into the equipment.

  As described above, the automatic filling device 1 according to the present embodiment can automatically pull out the folded inner bags 2 one by one by the bag feeding device 16 and position the inner bag 2 inside the drum can 6. After filling the filling gas from the filling nozzle 62 and bringing the inner bag 2 into close contact with the inner surface of the drum 6, the filling can be supplied and filled. Furthermore, the upper end part of the inner bag 2 after filling with the filling material can be sandwiched and sealed by the sealing device 18.

  Thereby, the inner bag 2 can be automatically loaded in the drum can 6, the filling can be efficiently automatically filled in the inner bag 2, and further, the filling can be reliably shut off from the outside and stored for a long time. Accordingly, it is possible to perform filling work and poison filling in a bad environment while increasing the filling efficiency of the filling material into the drum can 6, and in a state where the filling material is reliably shut off from the outside for a long period of time. Since it can be stored, it is possible to prevent leakage of odors from the inner bag 2 and thus the drum can 6, prevention of ignition, and the like.

In addition, the automatic filling device 1 includes the lid removing device 14 and the lid transporting conveyor 12 that also serves as a lid attaching device, so that the automatic loading of the inner bag 2 into the drum can 6 and the automatic filling of the filling material are more efficiently performed. It can be carried out.
In addition, before the drum can 6 is lifted by the lifter 44 by the sealing device 18, the inner bag 2 is slightly inflated while maintaining the folded state by prefilling the filling gas from the filling nozzle 62, and is in a hanging position. Since the inner bag 2 is reliably positioned in a substantially vertical position directly above the center of the drum can 6, the positional accuracy of the bag supply to the drum can 6 can be increased.

In addition, since the sealing device 18 includes the jacket 52 and the sealing bar 54, the sealing performance between the mouth portion 2a of the inner bag 2 and the filling nozzle 62 during automatic filling of the filling can be ensured. It is possible to reliably eliminate the leakage of the filler during automatic filling.
Further, the jacket 52 has an air supply port 64b and an air intake port 64c communicating with the outside, and the seal device 18 passes through the inner bag 2 via the air intake port 64b and the air exhaust port 64c before sealing the inner bag 2. By degassing, the inside of the inner bag 2 can be brought close to a vacuum state after filling. Thereby, prevention of odor leakage from the inner bag 2 and consequently the drum can 6, prevention of ignition, etc. can be realized more reliably.

The present invention is not limited to the above embodiment, and various modifications can be made.
For example, the inner bag 2 may be attached to a can container other than the drum can 6.
