Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a bag loading method in a bag loading device for a transport vehicle that automatically stacks bags in multiple stages on the loading platform of a transport vehicle.

[Prior art] As a device for automatically loading bags of cement, grain, etc. in multiple stages onto the loading platform of a transport vehicle, a bag loading section is used as shown in Utility Model Application Publication No. 58-48635. There is a device that is movable vertically, horizontally, and longitudinally relative to the loading platform of a vehicle and sequentially loads bags onto the loading platform.

The general loading method for these bag loading devices is to sequentially load bag loads from one row next to the driver's cab side by side, and when the first stage is finished loading, the second stage is loaded.
By stacking the first row and then the third row, the cargo is loaded to a predetermined height. When the first row is finished loading, the loading section is moved back, and in the same manner, the second and third rows are loaded sequentially to the rear of the platform. .

[Problems to be Solved by the Invention] However, when bag cargoes are loaded one after another from one end of the loading platform while being adjacent to each other, bag cargoes whose external shapes are easily deformed, such as cement bags, come into contact with adjacent bag cargoes. Frequently loaded at an angle,
It may become impossible to load the next bag on top of that bag, or even if the bag can be loaded, it may not be positioned correctly, so if multiple stacks are stacked, the bag may collapse.

Therefore, even if the loading of bags could be automated, there is still a worker on the loading platform who monitors and corrects the loading position of the bags, and complete automation has not yet been achieved.

Therefore, in view of the above points, the present invention aims to load bag cargo onto a loading platform without causing the cargo to disintegrate and achieve complete automation, and also to efficiently load bag cargo. It proposes a loading method.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a bag loading device for a transport vehicle in which a bag discharge part is movable in the front, rear, left, right, and up and down directions with respect to the transport vehicle. When stacking multiple bags on the loading platform of a transport vehicle, the lowest tier of bags is discharged and loaded every other bag onto the loading platform, and from then on, the dispensing section is placed directly above the empty space between the bags. position, open and close the delivery gate to deliver the bag to an empty space and load it, and then place the next bag on top of the bag and open and close the delivery gate to load it, stacking two bags at a time. The present invention provides a method for loading bags in a bag loading device for a transport vehicle, characterized in that bags are loaded in multiple stages on a loading platform.

Furthermore, the present invention allows the dispensing gate provided in the dispensing section to face downward and open on both sides, so that when loading bags while stacking two bags at a time as described above, the second bag is guided by the dispensing gate. To provide a method for loading bags in a bag loading device for a transport vehicle, which allows bags to be loaded in multiple stages without shifting by positioning the bags while loading the bags.

[Function] In the present invention, when discharging bags from the bag discharging section of the bag loading device for a transport vehicle and loading them onto the loading platform of the transport vehicle, the discharging section is first lowered to bring it close to the loading platform surface, and then The bags in the lower tier are delivered every other bag onto the loading platform and loaded.

Then, the dispensing unit is moved to the open space between adjacent bags loaded every other bag, and the bags are discharged and loaded. In this way, the bag to be loaded is guided by the bags on both sides, smoothly enters the empty space, and is correctly positioned without tilting. Furthermore, in order to improve loading efficiency, the next bag is delivered and stacked on top of that bag. In this way, subsequent loading is carried out in multiple stages by stacking two bags at a time in the empty spaces between adjacent bags.

In addition, when stacking two bags at a time in the empty space between bags, the first bag smoothly enters the empty space between the bags and is positioned, and the second bag is guided by a dispensing gate that opens downward on both sides. However, by loading the bag on top of the bag on the lower tier, the bag does not tilt and is correctly positioned directly above the bag on the lower tier. By using this method to load the second bag, it becomes possible to stack the bags in multiple stages without causing the loads to collapse.

[Example] Hereinafter, an example of the present invention will be described based on the drawings.

A conveyor 21 is provided in the chute section 20 to smoothly send the bags to the discharging section 15.
is arranged.

Reference numeral 22 denotes a conveyor for transporting and supplying bags to the chute section 20, whose upper end is pinned and fixed to the traveling body 12, and whose lower end is slidably and rotatably supported. The conveyor 2 moves up and down together with the elevating body 3 while sliding its lower end, and its upper end moves laterally as the traveling body 12 moves laterally.
The upper end of the chute 2 always faces the input portion of the chute 20.

Reference numeral 23 denotes a transport vehicle moving device for moving the transport vehicle back and forth.The rear wheel portion of the transport vehicle is placed on the moving body 24, and a chain 28 is passed around sprockets 26 and 27 arranged in the front and rear. A moving body 24 is attached to 28, and a drive motor 29 is driven to move the carrier back and forth.

As described above, the bag loading device 1 allows the bag discharge part 15 to be moved horizontally and vertically with respect to the loading platform of the carrier, and the carrier can be moved back and forth by the carrier moving device 23. By doing so, the dispensing section 15 can be moved back and forth relative to the loading platform.

Next, a method of loading bags onto the loading platform of a transport vehicle using the bag loading device as described above will be explained with reference to FIGS. 3 to 6.

When unloading bags from the bag unloading unit 15 of the bag loading device and loading them onto the loading platform of a transport vehicle, the bags are stacked one after another from the first horizontal row on the driver's cab side and loaded toward the rear of the loading platform. FIG. 1 is a diagram showing the starting state of stacking at the bottom of the row.

First, the loading method for the lowest stage is to lower the bag discharger 15 to bring it closer to the loading platform surface, open and close the discharge gate 16 while moving it laterally, and discharge the bags one by one to the loading platform as shown in Figure 1. I'll put it on. The numbers written on the bags indicate the loading order, and the following No.
It is expressed as 1, No. 2, No. 3, etc. bag cargo.

Next, as shown in Fig. 4, the dispensing unit 15 is moved to the upper part of the empty space between the adjacent No. 2 and No. 3 bags loaded with every other bag, and the bags are discharged from the dispensing unit 15. . The delivered bag load No. 4 is guided by the bag loads on both sides and smoothly enters the empty space and is correctly positioned without tilting. Next, payout section 1
5 may be moved to the upper part of the empty space between No. 1 and No. 2 bags to discharge the bags, but in the method of the present invention, in order to shorten the loading time of the bags, it is possible to move the bag to the position shown in Fig. 4. Then, another bag No. 5 is delivered from the delivery unit 15 and stacked. After this, loading is performed by stacking two bags at a time in the empty space between adjacent bags.

When the No. 5 bag is loaded, the unloading section moves to the upper part of the empty space between the No. 1 and No. 2 bags, and then the No. 6 and No. 2 bags are loaded.
7 bags of cargo will be delivered. When the bags are loaded in this way, stacking two bags at a time, there is an empty space every other bag in the second tier due to bags No. 5 and No. 7. Therefore, in the third tier, two bags are stacked one on top of the other in this empty space.

In the present invention, in order to increase loading efficiency, two bags are stacked one on top of the other as described above, and the first bag is guided by the bags on both sides and neatly enters the empty space between the bags. However, since the second bag is placed on top of the previous bag, depending on how it is placed, the bag may tilt. As shown in FIG. 4, although the dispensing unit 15 is moved as close as possible to the loading position to dispense the products, it cannot be said that the dispensing unit 15 will not tilt.

Therefore, in the present invention, the dispensing gate 16 of the dispensing section 15 is opened and closed symmetrically on both sides with the dispensing gate 16 pointing downward, and the second bag is opened downward as shown in FIG. Both sides of the bag to be discharged are in contact with each other, and the bag is placed directly above the lower bag in the correct posture.
The bag of cargo is positioned using the robot as a guide.

When dispensing is performed using the dispensing gate 16 as a loading guide for bag cargo in this way, after discharging the bag No. It stops in the open space between No. 1 and No. 2 bags, and then moves down by one bag, prolonging the loading time. However, the bags can be positioned in the correct posture without tilting, and the worker It becomes possible to stack multiple layers without having to modify the load.

FIG. 5 is a diagram showing bags stacked by repeating the above operations, and the bags are numbered to indicate the order of loading. Bags with a triangular mark next to the number are placed so that both sides of the bag to be delivered by the delivery gate 16 are guided.

Figure 6 is a diagram showing the loading state of the top layer, with No. 28, No. 29, and No. 3 bags on both sides of No. 25 and No. 27 bags.
The loading of one row is completed by loading the bags one bag at a time.

Then, the transport vehicle is moved forward by the transport vehicle moving device 23, and the next row is loaded using the same loading method as described above, and by repeating this process, the entire area of the loading platform is loaded with bags.

[Effects of the Invention] As described above, according to the present invention, when a bag is discharged from the bag discharge part 15 of the bag loading device 1 and loaded onto the loading platform of a transport vehicle, first, every other bag is placed on the lowest stage. After that, every other bag is loaded into the empty space between the adjacent loaded bags, so the bags on both sides act as a guide and smoothly enter the empty space and are positioned correctly. .
Furthermore, the next bag is delivered and stacked directly above the bag, and the loading is carried out by stacking two bags at a time, thereby increasing the loading efficiency.

Also, when stacking two bags at a time in the empty space between bags, the first bag smoothly enters the empty space between the bags and is positioned, and the second bag opens and closes symmetrically on both sides downward. By guiding the bags at the unloading gate 16 and loading them, the bags can be loaded in the correct posture without tilting directly above the bags on the lower tier, so it is possible to stack multiple tiers without causing the loads to collapse, making it easier to carry out the work. This eliminates the need for personnel to modify the load, making it possible to fully automate the bag loading device.
