Description

Field of technology to which the invention relates

The invention relates to equipment, namely to packaging for glass and a method for packaging glass for storage and/or handling and/or transportation and/or lifting. First of all, the invention is intended for packaging blocks (also called bags or bundles) of flat glass of the following sizes weighing no more than 2500 kg: 1605 x 2550 mm, 1800 x 2600 mm, 2250 x 3210 mm, 2550 x 3210 mm, but is not limited to this. The invention can be used in factories and factories of the glass industry and glass processing plants. The packaging according to the present invention is reusable because can be safely dismantled and installed on a new block of flat glass without damaging the structure.

State of the art

A device for lifting a glass package (equipment) is known from the prior art, which consists of two pairs of corner elements intended for installation on the four corners of a glass package (US patent No. 5678691, publication date - 10/21/1997). On the perpendicular sides of each of the corner elements there are brackets for fixing tapes in them. The tapes are designed for tying a package of glass simultaneously vertically and horizontally. On two corner elements, intended for installation on the upper corners of a vertically installed glass package, there are sling nodes (nodes for fixing slings in them). Moreover, the slinging units are located on the sides of the corners, i.e. on the sides adjacent to the vertical side of the glass package.

A significant disadvantage of this equipment is that the sling units are located on the sides of a vertically installed glass package, since when a large glass package is vertically lifted with a sling, the glass bends into an arc, which can lead to damage. Therefore, this equipment design cannot be used for lifting large glass. In addition, since the slinging unit is located on the sides of the glass package, in order to fix the corner elements on the glass and the possibility of lifting the glass with equipment, both horizontal and vertical fixation of the corner elements with tapes is necessary, which complicates the design of the equipment itself. Another disadvantage of the equipment is the complexity of its installation, due to the need for horizontal and vertical tying of the glass package with four pairs of tapes. Horizontal tying of large glass panes is especially labor-intensive, and it is necessary to pass tapes under the pyramid when tying, on which the glass is usually installed.

Also known is equipment for vertical lifting of glass, consisting of four corner elements for fixing them on the corners of a glass package (Chinese patent No. 201254355, publication date - 06/10/2009). A sling unit is made on two corner elements. The specified corner elements are intended for installation on the upper corners of the glass package in such a way that the side of the corner with the sling unit is adjacent to the upper horizontal end side of the glass package. On the sides of the corner elements there are recesses for placing tape in them for horizontal and vertical tying of the glass package. There are no recesses on the sides of the corner members where the sling assembly is located, since each sling assembly, consisting of a pair of eyes, is designed to accommodate the strap between the eyes.

A disadvantage of the design of this equipment is also that lifting the glass package is possible only with simultaneous horizontal and vertical tying of the glass package with tapes, which leads to labor-intensive installation of the device (especially with horizontal tying). When lifting the glass with the exception of the horizontal strapping, the upper corner elements turn out and are torn from the glass package, as a result of which the device cannot hold the glass package, which does not allow the known equipment to be considered reliable when lifting the glass.

Another disadvantage of this design is that the sling unit is made in the form of eyes, which allows the use of only a certain type of sling.

A device for lifting large glass windows is known from the prior art (Russian patent for utility model No. 203114, publication date - 03/22/2021), which was chosen as the closest analogue of the claimed invention. The device according to the closest analogue consists of a pair of corner elements connected to each other by two parallel metal strips, where on one of the corner elements there is a sling unit located between the metal strips, and the side of the corner element with the sling unit contains two sides. The corner elements are made with the possibility of installation on the oppositely located upper and lower corners of the glass package with its vertical tying with metal tapes and placement of a corner element with a sling unit on the upper corner of the glass package. Moreover, the upper corner element is configured to be installed on the glass package in such a way that the side of the corner element with the sling unit is adjacent to the upper horizontal side of the glass package.

The first main drawback of the device according to its closest analogue is the insufficient safety of glass from damage when it is placed inside this device. The second main disadvantage of the device of the closest analogue is that the sling unit is made in the form of eyes, which allows the use of only a certain type of sling. The third main disadvantage of the device according to its closest analogue is that the glass is located at the level of the floor/supporting surface, which makes it more susceptible to breakage or getting wet.

Disclosure of the Invention

The technical result of the present invention is to increase the reliability of packaging for storing, moving, transporting and lifting glass, to reduce the likelihood of damage/deterioration/contamination of glass, including inside the packaging itself, to increase the versatility of use, moving, transporting and lifting packaging, to reduce the likelihood of tension belts coming off when moving, transporting and lifting packaging, increasing the service life of glass, reducing labor intensity when installing packaging, simplifying the design while maintaining reliability, accelerating the glass packaging process and increasing the safety of the glass packaging process.

To achieve the above technical result, a packaging for glass is proposed, including a first group of corner elements containing an upper corner element and a lower corner element, a second group of corner elements containing an upper corner element and a lower corner element, a first pair of tightening straps and a second pair of tightening straps. Moreover, the upper corner element and the lower corner element of the first group are connected to each other by the first pair of tightening straps, and the upper corner element and the lower corner element of the second group are connected to each other by the second pair of tightening straps. Damping material is glued inside the corner elements. The upper corner elements contain a slinging unit in the form of a hook, and the lower corner elements are equipped with a group of supports.

According to the present invention, the corner elements can be made of steel.

According to the present invention, the tie belts can be made in the form of steel strips.

According to the present invention, damping material can be glued inside each corner element.

According to the present invention, each corner member includes a vertical side and a horizontal side, and a damping material can be bonded inside each side of the corner member. Also, each corner element contains sides.

According to the present invention, the damping material can be made of rubber or polyurethane.

According to the present invention, the support group may comprise three supports.

According to the present invention, the upper corner members and the lower corner members can be secured by a pair of tie-down straps with a lockless joint.

Also, to achieve the above technical result, a method is proposed for packaging glass for storage, moving, transporting or lifting, including placing glass on a stacker, installing upper corner elements on the upper corner parts of the glass, installing lower corner elements on the lower corner parts of the glass, vertical fixation with pairs of tightening belts upper corner elements with lower corner elements and slinging of the package using the slinging unit. In this case, the above-mentioned packaging for glass is used in the claimed method.

According to the present invention, a textile sling, a chain sling, a rope or a ring sling can be used, and the sling can be engaged by means of a hook-hook.

Increased reliability of packaging for storage, movement, transportation or lifting is ensured due to the design (device) of the packaging as a whole, including the presence of a glued layer of damping material inside the corner elements, which absorbs vibrations when moving sheet glass in space, leveling out the negative impacts onto the sheet glass inside the package itself. Also, the reliability of the packaging is ensured by the design of the sling unit in the form of a hook due to the possibility of using a reliable beam crane or, for example, a forklift to move the glass. In addition, the reliability of the packaging is ensured by the presence of a group of supports on the lower corner elements, which act as a limiter, preventing the tension straps from jumping off during movement, transportation or lifting.

Reducing the likelihood of damage/deterioration/contamination of glass is ensured primarily due to the presence of a group of supports on the lower corner elements, which allow you to lift the glass from the floor to avoid breaking, getting wet, getting dirty, etc. In addition, unlike the closest analogue, the claimed packaging ensures complete closure of the corner parts of the sheet glass, eliminating the risk of damage during storage, movement, transportation or lifting.

Increased versatility of use, movement, transportation or lifting of packaging is ensured by the fact that the sling unit is designed in the form of a hook, which allows the use of any type of sling for lifting, storing or moving sheet glass.

Reducing the likelihood of the tie-down straps jumping off is ensured by the presence of a group of supports on the lower corner elements, which act as a limiter for the tie-down straps when moving, transporting or lifting. In addition, special sides in the form of elongated cylindrical elements are provided on the upper corner elements.

Increasing the service life of glass is ensured by eliminating possible breakage, wetting, and contamination of glass during its movement, transportation and lifting through the presence of a glued layer of damping material inside the corner elements and the presence of a group of supports on the lower corner elements.

Reducing the labor intensity during packaging installation, simplifying the design and speeding up the glass packaging process, in contrast to the closest analogue, is ensured primarily by the use of a sling unit in the form of one element - a hook.

Increased safety of the glass packaging process is also ensured by using a sling unit in the form of a hook, because during the hooking, the slinger (person) is at a safe distance from the finished glass pack.
