[0002]
[Prior art]
Conventionally, a support base that supports the bottom of the bag is provided below the supply nozzle provided at the lower end of the weighing hopper, and a predetermined weight of content is supplied from the supply nozzle to the inside of the bag placed in an open state on the support base. A filling device for dropping and filling is disclosed in Japanese Utility Model Publication No. 49-43004.
Since the conventional filling device is a device that fills a light and hard-to-break powder, even if the content is dropped directly into the bag from the upper supply nozzle, the quality of the filled content is exceptional. There is no inconvenience. However, if the contents are relatively heavy and soft solids such as potatoes and onions, they may be damaged by a drop impact and the commercial value may be reduced.
[0003]
[Problems to be solved by the invention]
This invention makes it a subject to provide the filling apparatus which can be filled automatically in a bag, even if it is a heavy and easily damaged content, without being damaged by the impact of dropping.
[0004]
[Means for Solving the Problems]
Filling device of the present invention has established the supply port of the contents supply apparatus above the bag supporting platform for supporting the bag bottom, on both sides of the bag support base, the receiving rod of the extension building pair in parallel to face The pair of receiving rods are arranged so as to be movable toward and away from each other and can be moved up and down, and a lifting device is connected to the pair of receiving rods so that the contents are sandwiched between the pair of receiving rods. While close to each other so as to be received, it is possible to move away from the position above the bag support base and to move to a position below the bag support base.
[0005]
An empty bag is placed in an open state on the bag support, and a pair of receiving hooks are raised toward the bag mouth by an elevating device, and the pair of receiving hooks are sandwiched from the outside of the bag. In this state, the contents are discharged from the supply port of the contents supply device into the bag. Then, the contents are received on the way by a pair of receiving hooks that are close to each other, and the impact caused by dropping is reduced.
As the height of the contents deposited on the pair of receptacles increases, the pair of receptacles are gradually lowered by the lifting device, and finally the contents received by the pair of receptacles are bagged. After lowering to the bottom, the pair of receptacles are separated, and the accumulated contents are dropped into the bag.
By making the pair of receiving rods movable to the lower side of the bag support base, the bag can be supplied and discharged on the bag support base from the direction intersecting the axis of the receiving basket.
[0006]
A bag mouth gripping device that opens and supports the bag mouth can be provided above the bag support base. With this configuration, it is possible to prevent the bag mouth from closing or the bag from falling down during the supply of the contents .

[0015]
The lifting range by the lifting device 6 is such that when the pair of receiving rods 5 are in contact with each other near the top of the rotation when the rotating arm 15 is rotated, the pair of receiving rods 5 support the bag. This is a range that moves up and down between the table 2 and the supply port 3 ′ of the content supply device 3.
Further, when the lifting frame 19 is lowered to the lower limit position and the pair of receiving rods 5 are rotated downward, the pair of receiving rods 5 are moved to a position below the bag support 2 as shown in FIG. Therefore, it does not get in the way when the bag feeder 8 supplies the bag A above the bag support 2.
[0016]
The filling device 1 of the present invention is used as follows.
In advance, the rod of the air cylinder 23 of the lifting device 6 is extended to lower the lifting frame 19 and the tip of the rotating arm 15 is rotated downward so that the pair of receiving rods 5 are below the bag support 2. Place it in.
Further, the holding plate 9 and the suction cup of the bag mouth gripping device 4 are separated from each other.
In this state, one bag A is erected and supplied by the bag feeder 8 directly above the bag support 2.
[0017]
Next, both sides of the bag mouth of the bag A placed on the bag support 2 are clamped by the clamping plates 9 of the bag mouth gripping device 4, and a suction cup (not shown) is brought close to the front and rear surfaces of the bag mouth.
Next, the rod of the air cylinder 14 of the bag mouth gripping device 4 is retracted to bring the holding plates 9 closer to each other, and the suction cup is separated to open the bag mouth of the bag A.
Further, the rod of the air cylinder 23 of the lifting device 6 is retracted, and the lifting frame 19 and the pair of receiving rods 5 supported by the lifting frame 19 are raised.
[0018]
Thereafter, the rotary cylinder 17 is driven to rotate the rotating shaft 16 in the opposite directions, thereby rotating the rotating arm 15 and the pair of receiving rods 5 fixed to the tip thereof upward. The pair of receiving rods 5 are brought close to each other so as to sandwich the bag A from the front and rear, slightly below the bag mouth of the bag A. At this time, the distance between the pair of receiving rods 5 is slightly narrower than the diameter of the contents.
In this state, the supply port 3 ′ of the content supply device 3 is opened, and the content is discharged toward the bag A. The contents discharged from the supply port 3 ′ are once received by the pair of receiving rods 5 and do not fall directly to the bottom of the bag.
[0019]
Further, when the discharge of the contents is started, the rod of the air cylinder 23 of the lifting device 6 is slowly extended. Along with this, the elevating frame 19 and the pair of receiving rods 5 supported by the elevating frame 19 slowly descend together with the contents accumulated on the receiving rod 5, so that the height of the accumulated contents gradually increases. However, the apex is kept at a substantially constant distance from the supply port 3 ′.
When the discharge of the set weight of the content is completed, the supply port 3 ′ of the content supply device 3 is closed, and the height of the pair of receiving rods 5 substantially matching the upper surface of the bag support 2 (the height of the bag bottom). Then, the rotary cylinder 17 is driven to rotate the rotary arm 15 and the pair of receiving rods 5 downward, thereby separating the pair of receiving rods 5 and depositing on them. Drop the contents on the bottom of the bag.
[0020]
Next, the bag support 2 is vibrated and leveled so that the contents are uniformly filled in the bag A without any gaps. Finally, the bag A is carried out toward the bag mouth closing device or the like .
[0021]
【The invention's effect】
According to the configuration of the first aspect, even if relatively heavy contents such as potatoes are dropped into the bag from the upper content supply device, the contents are received in the middle of dropping by the pair of receiving hooks. The contents are gradually lowered toward the bottom of the bag, so that the contents are not damaged by the impact of the drop.
Further, it is possible to supply the bag above the bag support base and to discharge the bag after filling the contents from the direction intersecting the axis of the receiving rod.
According to the structure of Claim 2, it can prevent that a bag mouth closes or a bag falls down in the middle of supplying the contents, and a content spills out of a bag .
