Description

Pallet insertion type automatic ton bag packaging machine {Automatic bulk bag filling machine}

The present invention relates to a pallet-loading automatic tone bag packaging machine. More specifically, the tone bag stacked up and down can be placed in the correct position by reversing the direction of the entrance and can be put into the device, and the entrance part of the tone bag for which the raw materials have been input is completed with high bonding force. This is a pallet-loading automatic tone bag packaging machine that minimizes tone bag packaging defects through heat fusion.

In general, a ton bag refers to a bag containing more than 1 ton of contents, and is used when transporting or packaging contents such as fertilizers, minerals, chemical raw materials, grains, etc. to load and store. When opening a toned bag at a site handling powders such as flour, the toned bag is opened using a cutting tool such as a knife while the powder is exposed to the site, and then the powder is poured from the opened toned bag. As described above, the toned bag is opened. Since the bag opening operation is performed while exposed to the field, the powder scatters throughout the field and contaminates the work site. If the powder is a harmful chemical, there is a problem of causing damage to the human body. It had problems such as increased powder loss due to scattering on exposed work sites.

In order to solve this problem, the ton bag can be opened inside a closed space such as a barrel when the ton bag is opened using Korea Registered Utility Model Publication No. 20-0208551, "Powder Bag Opening Device," so that the powder can be opened to the outside. It is a device that cleans the surrounding environment as it is not exposed, prevents loss of powder, and can shake off a small amount of powder remaining inside. However, when the material in the tone bag hardens, it is inconvenient for a person to apply impact to the tone bag using a hammer or bat, and the configuration of the previously known opening device is complicated, making it difficult to provide with expensive equipment.

Meanwhile, the present applicant has developed the "Tone Bag Unloading System" in Korean Patent Publication No. 10-2024880. The "Tone Bag Unloading System" recognizes barcodes and determines the material in the tone bag, the weight of the tone bag, the ring direction of the tone bag, etc. Receive information from the tone bag so that the ring of the tone bag is supplied in the same direction. The ring of the tone bag is formed horizontally at a certain position to guide the clamp to be easily installed. Hold the ring of the tone bag and move it vertically and horizontally at high speed. It has a technical feature that prevents the tone bag from shaking when stopped, and pressurizes the inner contents to go down to the bottom when the tone bag is opened.

However, in the past, the entire process of ton bag supply, raw material input, packaging, and discharge was not automated, resulting in low productivity and workers being exposed to an unsanitary environment during the work process.

Meanwhile, most of the ton bags used in Korea are imported from China, Vietnam, etc., and are imported by shipping a pallet with a large number of ton bags stacked on top and bottom in a container. Here, if the pallet loaded with ton bags is put directly into the pallet-loading automatic ton bag packaging machine, production volume will increase. However, since ton bags are loaded on pallets with the bottom folded to a certain area, the ton bags are stacked top and bottom with the entrance direction reversed. The bags are loaded horizontally and not tilted. Accordingly, when supplying tone bags on a pallet into the pallet-loading automatic tone bag packaging machine, it is necessary to position the inlet direction of the tone bags correctly.
