Description

[Detailed Description of the Invention] [Industrial Application Field] The automatic bulk filling device of the present invention stores bulk materials such as cement, food, fertilizer, and other chemicals from silos into paper bags, plastic bags, and flexible container bags (flexible container bags). This invention relates to a device that automatically fills a bag with a certain amount into a container (), and after filling the bag, sews the opening of the bag with perforations to seal it, and then transfers and handles the bag.

[Conventional technology] Filling and sealing of loose bulk materials is mainly done manually by placing a paper bag or flexible container bag under the silo against the silo's discharge port and fixing it, and then manually or electrically operating the discharge port's switch to keep it in place. When the bags were full, they were tied together with string or linen robes and sealed. In addition, because the bag and the silo outlet were not in close contact with each other, dust was scattered around, causing a deterioration of the working environment.

[Problems to be solved by the invention] However, in order to perform these filling operations, there is a lot of dust generated (and the working environment is poor, such as hot weather), and moving heavy items such as bags requires significant physical strength. Moreover, the working conditions are simple and repetitive work, and it is difficult to find enough workers due to a serious labor shortage of young workers.In addition, the number of elderly people currently working is increasing year by year, and the labor force is increasing. Currently, there is a problem of not being able to secure enough personnel.As a countermeasure to these problems, various automatic filling systems are currently being considered, but as of now there is no suitable equipment, and automation, which is inexpensive and easy to handle, is currently being considered. The reality was that the arrival of the equipment was long awaited.

[Means for Solving the Problems] Therefore, in order to make it possible to efficiently, safely, and automatically fill and seal these bulk materials, the automatic bulk material filling device of the present invention has the following features: An electric truck capable of reciprocating on a traveling rail installed directly below a silo in which bulk materials are stored; a box having a vertically movable receiving port provided on the electric truck and fitted into the silo discharge port; This is an automatic bulk material filling device consisting of a sewing machine for sewing flexible container bag intakes installed in the middle of the traveling rail, and a control panel that controls the start and stop of various power means. A hanging column that suspends a hand and tilts when filling bulk materials into a bag, a clamp mechanism that attaches and grips the empty bag intake port to the bag mouth attachment port of the receiving port, and a clamp mechanism that connects the receiving port to the silo discharge port. The structure includes a mounting column which is equipped with a power means at the upper end and which is pivotally connected at the lower end so as to be tiltable.

[Function] In the automatic bulk filling device of the present invention, after the empty bag hanger of a paper bag or flexible container bag (hereinafter referred to as bags) is suspended on a rack hanger column mounted on an electric trolley, the electric Transfer the trolley to the stopping position directly below the silo, attach and grip the empty bag intake port to the lower end of the container's receiving port using the clamp mechanism installed at the top of the mounting column, and raise the receiving port so that it hits the silo discharge port. After they are in close contact, open the on-off valve of the silo and let the bulk material fall into the bag. At this time, as the bag is filled with loose items, the lowest part of the bag, which had been suspended from the hanger column, lands on the electric trolley as described above, and the hanger is moved so that the bag can maintain its normal full shape. The column tilts to lower the bag. When filling is completed, the opening/closing valve is separated from the closing bag intake port and the peeler receiving port, and the electric trolley starts moving to the position of the sewing machine installed midway along the travel rail, and then stops. At this time, the sewing part of the sewing machine is lowered from above to the height of the upper end of the bag intake, and guided by the guide and guide roller of the sewing machine, the circular or square intake is aligned with a straight line, and the sewing machine It is sutured at the suture section.

After this work is completed, the sealed bags are transported to the loading dock at the end of the running rail while being loaded onto electric trolleys.
Here, it is unloaded onto the loading platform of a transport vehicle such as a truck using a forklift or a crane device, and then shipped to its destination. The empty electric trolley is moved towards the silo again, and if there is a bag loading machine in front of the silo, the empty bag hanger is suspended from the hanger column by the bag loading machine, or by hand. , the bag's intake port is set in an open state (circular or square).
