Description

The utility model relates to the field of containers for storage and transportation of products and materials, namely to containers with detachable elements and can be used for storage and transportation of wire coils.

Known reusable container containing parts for its assembly and fixation [1].

However, this device is difficult to manufacture and is not intended for storage and transportation of wire coils.

A collapsible box is also known, comprising walls interconnected by rods connected to the lid and the bottom, and the walls, lid and bottom at the junction points with each other have grooves that are combined at adjacent parts with their valleys and protrusions through which the closing rods are passed [2].

However, this technical solution has drawbacks - it is laborious to manufacture and is not intended for storage and transportation of wire coils.

In addition, a reusable collapsible container is known for storing and transporting bulk, grease and liquid products [3]. The container comprises a cylindrical body with a blind bottom and a top having a neck, a lid and annularly controversial orienting elements.

But this container also has a number of disadvantages: it is labor-consuming to manufacture and cannot be used for storage and transportation of wire coils.

Also known collapsible container for storage and transportation of goods [4].

The disadvantages of this container are: the complexity of its manufacture and the inability to pack, store and transport coils of wire.

The closest analogue to the claimed technical solution is the packaging of brass wire for the shoe industry in accordance with GOST 5529-75, p.5.7. [5].

The technical task of the utility model is packaging designed for storage and transportation of wire coils of any sizes produced by the industry.

The technical problem is solved in that the package for storage and transportation of wire coils, contains an apron of polypropylene fabric, sewn from the upper and lower sides, with the formation of channels for pulling and placing cords through the flashing, moreover, these packaging details provide cover for the wire coil lap on all sides with an overlap width of 100 ÷ 120 mm, while the length (L), the width (B) of the apron and the length of the cord (L ₁ ) in mm are found depending on the height of the wire coil (h), its inner (d ₁ ) and the outer diameter (D) of the holes zheny:

L = 3 (Dd ₁ ): 2 + 3h mm,

B = πD + 100 ÷ 120 mm,

L ₁ = B + 150 ÷ 200 mm.

Moreover, the relationship of the members of each mathematical expression, depending on the size of the coil of wire (shown in figure 2), height (h), inner diameter (d ₁ ) and outer diameter (D) is as follows:

1. L is the length of the apron.

Dd ₁ - the difference between the outer and inner diameters of the bay.

3 - the number of shelters of the wire bay.

2 - only half of the difference in diameter is hidden (or completely the difference in radii)

3h - the bay takes refuge 3 times in its height.

Hence, the length of the apron (L) in accordance with the first expression is:

L = 3 (Dd ₁ ): 2 + 3h mm.

2. B - the width of the apron.

The width of the apron (B) should provide cover for the wire coil with an outer diameter (D), while the circumference of the diameter (B) is D with an overlap width of the outer diameter (D) of 100 ÷ 120 mm.

Hence, the width of the apron in accordance with the second expression is:

B = πD + 100 ÷ 120 mm

3. L ₁ - the length of the cord.

The length of the cord (L ₁ ) is equal to the width of the apron (B) + 150 ÷ 200 mm. This, as indicated above, ensures that the cord is tied with a bow when assembling the package and excludes accidental contact with load-gripping devices and eliminates unintentional unpacking of the package during loading and unloading.

With this technical solution, it is possible to pack wire coils of any sizes produced by the industry with minimal cost.

The essence of the proposed technical solution is illustrated by drawings.

Figure 1 and figure 2 shows the packaging details.

Figure 1 shows an apron with cords: 1 - an apron, 2 - a cord, 3 - a seam, 4 - a channel for a cord, L - apron length, B - apron width, L ₁ - cord length, dimensions in mm.

The cord (2) is longer than the width B of the apron (1) by 150 ÷ 200 mm., 150 mm - the minimum excess of the length of the cord (2) over the width B of the apron (1) - ensures that the cord is tied with a bow when assembling the package.

200 mm - the maximum excess of the length of the cord (2) over the width B of the apron (1) - ensures the optimal length of the loop when assembling the container. If the length of the cord (2) exceeds the width B of the apron (1) more than 200 mm, accidentally grabbing the packing bow and its unpacking during loading and unloading is not excluded.

Figure 2 shows the coil of wire with a height (h), an outer diameter (D) and an inner diameter (d ₁ ).

Figure 3 shows a package with a coiled wire (1) placed in it, with an opening (2) for load gripping devices, an overlap butt (3), bows (5 and 6), after packaging is completed by pulling the cord.

Figure 4 shows a coil of wire (1) with a hole (2) and an apron (6) during the packaging of the bay.

The assembly of the packaging and the process of packing the coils of wire into it is carried out sequentially in 3 positions (positions 1-3).

1st position. An apron (6) (see Fig. 4) covers the outer surface of the bay (1). Then pull the cord (4) and tie it with a bow (5). The apron is spread over the outer surface of the bay (1). As a result, an overlap joint is formed (3).

2nd position. An apron (6) (see figure 4) is pulled through the hole (2) of the wire coil (1) to cover the inner surface of the coil (1). As a result of this, an overlap is formed (3). Then the internal lap joint (3) is straightened and the apron (6) extends all the way.

3rd position (see figure 4). Secondary covering of the outer surface of the bay (4) is carried out, the outer joint overlap is straightened (3) and the second end of the apron is pulled together by the second cord (4) of the apron (6) and tied with a second bow (5). The packaging is complete. In the packaging of the coil of wire (see figure 3), shows the first (5) and second (6) bows.

Dismantling of the packaging (see figure 3) after storage and transportation is carried out in the reverse order, i.e. the first bow (5) of the cord (4) is untied and then everything is done in accordance with positions 3-1.

Examples of specific performance

Example 1

In the wire workshop of the Magnitogorsk Hardware and Metallurgical Plant OJSC MMK made experimental packaging of steel wire coils with an outer diameter (D) 800 mm, an inner diameter (d ₁ ) 400 mm and a height (h) 1200 mm using packaging according to the prototype (GOST 5529- 75 p.5.7.) And in accordance with the claimed utility model, the following results were obtained.

The packaging capacity of the bays using the proposed technical solution increases by 20-30%, while the cost of packaging is reduced by 5.3 times.

Example 2

In the wire workshop of the Beloretsk Metallurgical Plant, larger bays were packaged with an outer diameter (D) 1200 mm, an inner diameter (d ₁ ) 400 mm and a height (h) 1400 mm. When packing larger bays, productivity increases by 35-40%, the cost of packaging decreases 7.2 times.

Thus, the claimed technical solution allows, in comparison with the prototype, to increase productivity by 20-40% while reducing the cost of packaging from 3.5 to 7.2 times.
