Description

The invention relates to packaging equipment, namely to devices for packaging various objects (products, objects, goods) by wrapping (wrapping) them in a packaging (wrapping) material, mainly in a stretchable polymer film, also called a stretch film. Such devices are used for packing objects (products) to be transported in order to ensure ease of transportation and protect their surfaces from contamination and damage.

When transporting various objects, for example, boxes, goods, production items, etc., when delivering various goods from shopping or logistics centers, including those packed in boxes, packaging is an integral technological operation. It is important to optimally place the item in the process of packaging and ensure uniform and efficient wrapping in the packaging material.

Currently known devices for packing bulky items have large dimensions and a complex structure.

For example, semi-automatic horizontal wrappers are known [Electronic resources. Resource access mode: https://www.tk-goldenpack.ru/upakovchik_horizontal_poluavtomat_plasticband_neleo_50; http://www.one-pack.ru/orbitalnye-upakovschiki - free], designed for packing long objects, such as profiles, moldings, furniture parts in stacks, etc. Their disadvantages include a limited scope, large dimensions and design complexity.

Known electric packers [Electronic resource. Resource access mode: https://wrent.sk/en/product/wr1050t-2/ - free], their disadvantages include unreliable fixation of the packed item and a limited scope due to the table, which allows packing only items of a certain shape.

Known manual packer [Electronic resource. Access mode to the resource: https://www.instagram.com/p/B_kX_D1BIjq/ - free], its disadvantages include low packing speed, relatively high workload on the operator when packing a large volume of products.

The technical result of the claimed invention is to increase the automation and speed of packaging while simplifying and improving the reliability of the design.

This technical result is achieved due to the fact that the orbital device for packaging includes a central holder and a gearbox, made with the possibility of connection with the support, and the central holder passes through the hollow output shaft of the gearbox, which is associated with at least one lever for placing a reel with packaging material, at least one guide is installed on the holder, which is configured to hold the packaged item.

Options for the development of the main technical solution are possible, consisting in the following:

- the central holder and the gearbox are connected to the mount to the support;

- a lever for placing a bobbin with packaging material on it is connected directly to the output shaft of the gearbox;

- a lever for placing a bobbin with packaging material on it is connected to the output shaft of the gearbox through an intermediate link, which is installed between the output shaft of the gearbox and the central holder and is configured to transfer rotation from the output shaft of the gearbox to the lever fixed on it;

- the lever is fixed on the end surface of the intermediate link;

- the diameter of the end surface of the intermediate link, on which the lever is fixed, has a larger diameter than the diameter of the output shaft;

- the central holder rests on the intermediate link through the bearing;

- the guide is mounted on the holder with the possibility of rotation relative to the installation axis;

- the guide is provided with at least one stop or grip.

Thus, due to the combination of essential features, it was possible to increase the automation and speed of packing the item while simplifying and increasing the reliability of the design, thanks to the compact and reliable combination of the functions of the item holder and the lever drive with the reel in one unit. At the same time, the geometric center of the packaged item is located as close as possible to the center of rotation of the lever with the reel, which makes it possible to achieve optimal placement to ensure uniform packaging. The presence of at least one guide with the possibility of holding the packaged item allows you to fix the item of various configurations, which expands the scope of the claimed invention.

In essence, it became possible to automate and speed up the process of preparing cargo for shipment.

The essence of the claimed invention is illustrated by the figures and the following description.

On FIG. 1 shows an orbital packaging device (side sectional view).

On FIG. 2 shows a general view of the packaging device with the item installed.

On FIG. 3 shows an embodiment of one guide for holding the item to be packed.

On FIG. 4 shows a front view of a packaging device with two guides for holding the packaged item, separated by an angle A. The packaged item is shown as transparent.

On FIG. 5 shows a front view of a packaging device with two guides for holding the packaged item, set apart at angle B. The packaged item is shown as transparent.

Orbital device for packaging (Fig. 1-5) includes a central holder 1 and a gearbox 2, made with the possibility of connection with a support (not shown in the figures).

The central holder 1 passes through the hollow output shaft 3 of the gearbox 2.

The output shaft 3 of the gearbox 2 is connected to at least one lever 4 for placing on it the bobbin 5 with the packaging material.

At least one guide 6 is installed on the holder 1, which is configured to hold the item 7 to be packed.

The holder 1 and the gear 2 can be connected directly to the support (not shown in the figures) or to the attachment point 8 to the support (not shown in the figures), for example, using fasteners. The support can be made mobile, for example, in the form of a vertical rack, or stationary, for example, in the form of a wall. The node 8 fastening to the support can be a bracket, plate, bushing and any other device with which the reducer 2 and the holder 1 can be fixed on the support.

Lever 4 has a shoulder length that allows orbital winding of a fixed object 7 without catching it. The lever 4 is provided with means (rod, rod) for rotatably mounting the bobbin 5 with packaging material, such as stretch film, paper and any other packaging material.

The lever 4 can be connected directly to the output shaft 3 of the gearbox 2 or connected to it through an intermediate link 9. Direct connection is possible only if the output shaft 3 of the gearbox 2 is used with a suitable fitting end diameter.

The intermediate link 9 is installed between the output shaft 3 of the gearbox 2 and the central holder 1 and is configured to transmit rotation from the output shaft 3 of the gearbox 2 to the lever 4 fixed on it, which is fixed on its end surface.

The intermediate link 9 is attached to the hollow output shaft 3 of the gearbox 2 with the help of a nut 10 installed on the side opposite to the lever 4.

To simplify the design, the diameter of the end surface of the intermediate link 9, on which the lever 4 is fixed, has a larger diameter than the diameter of the output shaft 3.

In the case of an intermediate link 9, the holder 1 rests on it via a bearing 11. The bearing 11 is preferably a radial rolling bearing for absorbing radial loads. The type and type of bearings is determined based on the required characteristics and operating mode of the device (load, rotation speed, efficiency, resource, etc.).

Due to the use of the bearing 11, it is possible to exclude the contact of structural elements and, as a result, to increase the load-bearing capacity of the device, the durability of the structure and its maintainability.

The output shaft 3 of the gearbox 2 can be connected to one, two or more levers 4, which can have, for example, different arm lengths, which will allow you to choose the optimal lever 4 for a particular packaged item 7 or, for example, provide the ability to accommodate several reels 5 of different films when packing.

The gearbox 2 is configured to transmit torque to the lever 4 through the shaft 3. The gearbox 2 is a drive, namely, a gear motor or a gearbox with an electric motor. The packaging device is equipped with a power supply unit (not shown in the figures) and a control unit (not shown in the figures) connected to the electric motor and ensuring its operation. Power can also be provided directly from the mains.

The guide 6 can be fixed on the holder 1 or can be rotated relative to the installation axis (Fig. 3). If there are more guides 6, they can also be fixedly fixed on the holder 1 or mounted on it with the possibility of changing the angle between them (for example, the angle A and B in Fig. 4 and 5, respectively), providing the ability to adjust the fastening of the object 7 .

Several guides 6 can be used in the design, depending on the dimensions and shape of the item 7 to be packed.

Each guide 6 is provided with at least one means 12 for holding the item 7 to be packed, such as a stop or grip. A slot 13 can be formed in the guide 6, along which, for example, on a carriage or a plate, the holding means 12 moves to adjust to the dimensions of the object 7.

The claimed device works as follows. A bobbin 5 with packaging material is placed on the lever 4. On the guides 6 place the item 7 that needs to be packed and throw the edge of the packaging material over it. The electric motor is turned on, which, through the gearbox 2, begins to rotate the lever 4 with the reel 5, which, making an orbital movement around the holder 1 and the object 7, packs it.
