Description

[Detailed description of the invention] Industrial application field This invention is a packaging bag, especially for the transportation of fixed-sized items by ship or freight car, to prevent cargo from collapsing during transportation, and to pack the bag without using equipment such as a rotary lift at the loading port. To provide a bottomless packaging bag for storing and transporting fixed-sized objects suitable for attaching a pallet to a pallet, ready-to-pack bags, and collection by simply placing a bag on a pallet, removing a lifting rope, replacing it with a bottoming rope, and hanging it.

Conventional technology Conventionally, this type of bottomless packaging bag for storing and transporting fixed-sized objects was
The backing of the pallets at the unloading port was done by using a rotary lift from the packaging bag or by labor, and there were no cases where the bottom part opened or the pallets were separated.

Problems that the invention aims to solve: Therefore, with the conventional method, it is necessary to use other equipment such as a rotary lift for loading and unloading, and it is labor-intensive, and there is a risk of the cargo collapsing. There were various problems such as:

Means for Solving the Problems As a result of intensive study to solve the above-mentioned problems, the inventor of the present invention solved the above-mentioned problems at once by using a combination of a specific packaging bag and an upper load prevention cover. We discovered what could be done and arrived at this invention.

That is, the present invention is composed of a lower bottomless packaging bag a and an upper cargo collapse prevention cover b. side parts 2, 2' necessary to surround the side parts 3, 3', which can be divided and separated;
3'', 3, lifting ropes (including bands) 4, 4' attached to the side parts 3, 3' and 3'', 3, respectively, bottoming ropes attached to the side parts 2, 2' 5 (including the band), the upper cargo collapse prevention cover b consists of a top cover portion 6 that is slightly larger than the area of the top surface of the cargo, a side surface portion 7 of a size necessary to surround the cargo, and an intermediate fastener attached to the side surface portion. This invention relates to a bottomless packaging bag for storing and transporting shaped objects, which is made of rope 8.

The lower bottom packaging bag of the present invention is manufactured, for example, as follows.

Using a woven fabric made of strong and flexible fabric, the bottom part has a width (area) slightly larger than the backing area made up of the two bottom parts to be divided, and the lower side part of the cargo is surrounded by the two bottom parts. If you form side parts (side parts) for each side part, form rope passage parts in each divided side part, attach lifting ropes (bands) to each part, and lift these lifting ropes at the same time. To enable lifting with the bottom formed. A lower bottom packaging bag can be manufactured by forming a rope passing portion on each of the two undivided side portions and attaching a bottoming rope (band) thereto.

The top cover for preventing collapse of cargo used in combination with the lower bottom packaging bag of the present invention can be applied to the one described in Utility Model Application No. 57-22518 (Utility Model Application No. 58-125132), which was previously proposed by the inventor of the present invention. For example, by using a woven fabric made of a fabric strong enough to withstand the collapse of the load, form a top covering part slightly larger than the area of the top surface of the load and a side part necessary to surround the load, and form a rope passage part in the side part. , it can be manufactured by attaching an intermediate tightening rope to it.

The woven fabric used to manufacture the lower bottom packaging bag of the present invention is a strong one, such as a plain weave made of flexible fabric such as fiber-reinforced synthetic resin.
As the lifting rope (band) and the bottoming rope (band), strong ropes (bands) that are normally used for this type of packaging bag are used.

In addition, the woven fabric used to manufacture the upper cargo collapse prevention cover of the present invention can be a strong woven fabric, for example, the same quality as the woven fabric used for the above-mentioned lower bottom packaging bag, but it does not need to be so strong. . In the case of a strong woven fabric, it can be used repeatedly, and if it is not strong, it can be used once and as a disposable item. Further, the side surface of the upper cargo collapse prevention cover can be made to cover most of the side surface depending on the type of cargo, or it can be made to cover only the upper side surface to the extent that the cargo does not collapse. , covering only the corners of the cargo, etc., can be adopted. Moreover, the number of intermediate tightening ropes can also be two or more.

As shown in FIG. 1, the bottomless packaging bag for storing and transporting fixed objects of the present invention has a lower bottomless packaging bag and an upper cover to prevent cargo from collapsing.

Function: In the bottomless packaging bag for storing and transporting fixed objects of the present invention, after the middle tightening rope 8 of the upper cargo collapse prevention cover is tied (position 14 in Fig. 1), the bottoming rope 5
on top of the cargo, hang one of them on the middle tightening rope (position 15 in Figure 1), pull the lower rope for removing the bottom 5, and remove the upper cover and the middle tightening rope 8.
It is even more effective if you wrap the inside and pull it toward the bottom, then tie it in a way that makes it easy to untie. The lifting ropes 4, 4' are hung on the hooks for movement.

At the unloading port, lower it onto the pallet, untie the bottoming rope 5, remove the lifting ropes 4, 4',
By hanging this rope by replacing it with the bottoming rope 5, the drawer pallet can be placed on its back without the load collapsing due to the effect of the upper cargo collapse prevention cover b. (or,
For storage bags that tend to collapse easily, it is possible to make sure that they are completely secure by laying a cross-shaped rope at the bottom of the bag and tying it to the upper cover's inner tightening rope. It becomes possible.

Examples Examples of the present invention will be described below based on the drawings, but the present invention is not limited thereto.

In this example, the backing area is 1100mm x 1100mm based on freight car loading, and the backing area is 1200mm for shipping.
I will explain using a size that can be used for both 1200mm x 1200mm (if the back is 1100mm x 1100mm, the excess will become a side wall when lifting and there will be no problem).

The bottomless packaging bag for storing and transporting fixed objects of the present invention shown in Fig. 1 uses a plain weave fabric made of strong flexible fabric such as fiber reinforced synthetic resin,
The bottom and side parts of a bottomless packaging bag consisting of the bottom part 1, side parts 2, 3, 3' and the bottom part 1', side parts 2', 3'', 3 are manufactured, and a rope passage part 9 is attached to the top of the side part. ,9',9'',9 and 10,10',10'',1
0 is created. Next, as shown in Figure 3,
A cylindrical rope passing portion 9 at each end of the side surfaces 2, 2' and 3, 3', 3'', 3,
9', 9'', 9 and 10, 10', 10'', 10
The binding ropes 11, 11' are passed through the connecting ropes 12, 1 connected to the binding ropes 11', respectively.
2' is connected in a ring to produce a packaging bag with a lower bottom.

Lifting ropes 4, 4' and bottoming rope 5
The connection method is to make both ends of the lifting ropes 4, 4' into rings in advance, pass them through the binding rope 11, and tie them together.
The bottoming rope 5 is a binding rope 1 that has been made into a ring shape in advance.
It is passed through the connecting rope 12 connected to 1' and tied.

However, if this packing bag with the bottom bottom removed is used to transport the bag on its back, it will not be sufficient to prevent the cargo from collapsing during transportation, and in the case of fixed-quantity packaging, it will be difficult to handle stacking at the top and load when the bottom is removed. Since there is a problem in preventing the cargo from collapsing, the present invention further uses an upper cargo collapse prevention cover in combination. As shown in Fig. 1, this upper cargo collapse prevention cover uses a plain weave fabric made of the same fiber-reinforced synthetic resin fabric as the lower bottom packing bag, and has an upper covering portion 6 with an area slightly larger than the area of the top surface of the cargo.
A side part surrounding about 1/4 of the cargo side part is formed, a cylindrical rope passage part 13 is formed in the side part, and the inner tightening rope 8 is passed through it.

Effects of the invention The cargo can be easily pulled out with a simple operation based on the divided structure of the bottom of the lower bottom packing bag and the extremely simple structure of pulling up with the rope for removing the bottom, and in combination with the top cover to prevent cargo from collapsing. This allows you to load the bag on its back and collect the packaging bag without the load collapsing.
Loading and unloading becomes possible very easily without the use of other equipment such as rotary lifts.
In addition, the bottomless packaging bag for storing and transporting fixed objects of the present invention has a simple structure as described above, so it is easy to manufacture and has advantages such as being inexpensive and economical.
