Description

The claimed technical solution relates to vehicles driven by hand, namely trolleys designed to move metal tapes.

There are models on the market used for a similar purpose.

Known trolley unwinder for steel and polyester tape TR-304 ¹ ( ¹ https://ukrtehnika.com/product/tp-304-telezhka-razmotchik-dlja-stalnyh-lent). Unwinding trolley for steel and polyester tape TR-304 is used for packing with steel tapes, equipped with a tool box, as well as a brake for the tape. The design of the trolley allows you to place coils with a diameter of 600 mm and a tape width of 190 mm on it, the inner diameter of the spool is 406 mm. The overall dimensions of the unwinder are 600×510×1100 mm.

The dispenser-unwinder declared for registration is simpler and quieter in operation, due to the fact that the tape spins on rubber wheels, and not on bare bearings. The closed body design provides more convenient operation, since there is no risk that the tape coil will shift or fall out, which is also a disadvantage of the TR-304 product.

The technical problem to be solved by the claimed utility model is to overcome the lack of ease of use of previous samples, in particular, the above model of the TR-304 trolley designed to move metal tapes, as well as to eliminate the need to purchase additional devices, namely several devices for tapes of different sizes.

These features of mass-produced dispenser-unwinder trolleys have identified the problems that the consumer faces when using them and the solution of which will improve the consumer properties of these devices that are in demand by consumers.

A dispenser-unwinder (PROTOTYPE) is known according to the RF patent for utility model No. 199947 dated March 23, 2020, published on September 29, 2020, which contains a U-shaped frame, while the upper part of the metal frame is located at an angle, forming a handle, at the bend of which metal triangular guides are welded, to which a tool box is freely attached with the help of threaded rivets and a screw, triangular guides made of metal sheet are welded to the lower part of the frame, to which a U-shaped support from a metal pipe is welded, and metal is welded between the guides a profile along the edges of which there are wheels with bearings fixed with a nut-bolt connection, a metal cover 3 mm thick is welded to the frame in the center, to which, in turn, a holder for the drum axis is welded, made of sheet steel 3 mm thick, and the axis itself, made of a metal bar, the drum includes two circles, made made of a metal pipe, with 6 flat metal spokes extending from each circle, welded to a flat metal circle with a hole in the center, put on the axis of the drum, while 4 holes are made in the spokes for attaching metal guides for coils of tape of four standard sizes , washers and a wing nut are used to fix the drum on the axis, a metal bar equipped with a rubber tube is fixed on the frame at the level of the drum.

The common features of the claimed technical solution and the prototype of the dispenser-unwinder according to the RF patent for utility model No. 199947 are the presence of a refractory frame, wheels for moving, and also wheels for facilitating the unwinding of the metal tape.

The differences between the prototype and the proposed technical solution are due to the design features and the use of a different principle of unwinding the tape. The prototype includes studs on which the drums are put on, and the tape is spinning, and in the claimed technical solution, the tape is twisted from the inner wheels. The advantage of the proposed solution is that the weight of the tape can reach 90-100 kg, while in the prototype the weight of the tape is not more than 60 kg.

The main disadvantage of the prototype according to the patent of the Russian Federation for utility model No. 199947 is the impossibility of installing bays for tapes of different widths, the soft unwinding of which is ensured by the use of rubber wheels.

The technical problem to be solved by the claimed utility model is the insufficient ease of operation of known models of trolleys designed to move metal tapes, and the need to purchase several devices for tapes of different sizes. Or, in practice, their complete absence. And the related forced need for employees of warehouses and transport companies, as they say, to work from the floor. And knowing that the weight of the tape coil is from 50 kg, employees, as a rule, do not transfer it from place to place of direct packaging, but cut off the amount of tape by eye, which, of course, leads to losses, because. it is impossible, as a rule, to measure by eye without waste. Therefore, the claimed utility model is ergonomic, as it also protects the health and backs of employees and helps to work economically.

The purpose of the development of the proposed technical solution is to expand the functionality of the dispenser-unwinder, in particular, the possibility of using different widths in the range from 19 to 32 mm, which leads to simplified operation.

The technical task is to create such a device that would be more convenient to operate and move to the place of work, as well as allow the use of coils of several sizes and various types of tapes.

The technical result of the claimed utility model is the convenience of storage and movement.

The essence of the proposed technical solution lies in the fact that the dispenser-unwinder includes a frame, a body, wheels for moving and wheels to facilitate the unwinding of a metal tape, and the frame is U-shaped, made of a pipe and consists of two parts connected by a fastener of the "mother" type. -dad" and three metal bolts, and the upper part of the frame is located at an angle, forming a handle, while in the lower part of the frame there is a base with the help of welded guides from a sheet, to which, in turn, a U-shaped support from a pipe is welded, ensuring stability , and a profile is welded between the guides, along the edges of which there are wheels with bearings, fixed with a wrench-screw connection, and a tool box is attached to the frame at the back with a wrench-screw connection, and a metal case is attached to the frame in front to accommodate the tape coil, while the rear wall of the housing, the lower part of which is placed in the corresponding grooves on guides, is attached to the frame with a wrench-and-screw connection, and the front wall of the case is attached to the back with metal brackets and a wrench-screw fastening, while the lower part of the front wall is placed in the corresponding grooves on the guides, and to facilitate the process of unwinding the metal tape in In the lower part of the body, two wheels are installed between the walls, which are fixed with studs and nuts.

The dispenser-unwinder can be assembled for a larger roll of tape.

The claimed technical solution is illustrated by drawings Fig.1 - Fig.4.

The drawings of the inventive dispenser-unwinder shows the following types.

Fig.1 - front view;

Fig. 2 is a side view;

Fig. 3 is a bottom view;

Fig. 4 is a sketch of a general view of the dispenser-unwinder.

In this case, the following elements are present in the images:

1 - U-shaped metal frame

2 - Tool box

3 - Front wall of the case;

4 - Rear wall of the case;

5 - U-shaped support from a metal pipe;

6 - Wheels for moving the dispenser-unwinder;

7 - Nut-screw connection;

8 - Short bracket;

9 - Guide;

10 - Wheels to facilitate the unwinding of the metal tape.

The utility model is made as follows.

U-shaped metal frame 1 is made of a metal pipe. The upper part of the metal frame of the device is angled to form a handle. The frame 1 consists of two parts connected at the attachment point using a mating type "mother-dad" and three metal bolts.

Guides 9 made of a sheet of metal are welded to the frame 1 below, to which, in turn, a U-shaped support 5 made of a metal pipe is welded, which ensures the stability of the dispenser-unwinder, and a metal profile is welded between the guides 9, along the edges of which wheels 6 are placed for moving dispenser-unwinder with bearings, fixed with a nut-screw connection 7. Together this forms the base of the dispenser-uncoiler.

A box for tools 2 is attached to the frame 1 at the back using a nut-screw connection 7. A metal case is attached to the frame 1 at the front to accommodate the tape coil. The rear wall 4 of the body is attached to the frame 1 using a nut-screw connection 7, the lower part of which is placed in the corresponding grooves on the guides 9. The front wall 3 of the body is attached to the rear wall 4 using a metal bracket 8 and a nut-screw connection 7, the lower part the front wall 3 is placed in the corresponding grooves on the guides 9.

To facilitate the process of unwinding the metal tape in the lower part of the housing between the walls, two wheels 10 are installed, which are fixed with studs and nuts.

Dispenser-unwinder works as follows.

Metal packing tape for strapping goods is produced and sold without internal spools (drums, reels). The finished coil of metal tape is installed in the dispenser-unwinder by lowering it into the hemispheres, and rests on two wheels in its lower part. The free end is threaded into a special hole in the bracket 8, on top of the hemisphere, on the right or left at the request of the user. Then the transport loops are cut off from the bay itself and the dispenser-unwinder is ready for work.

Next, the operator brings the dispenser-unwinder to the load.

Pull the tape to the desired length, tie the load and cut off the tape. Thanks to a special hole (window) in bracket 8, the free end of the tape is fixed and prevents the tape coil from unwinding or tangling, because the bay itself is densely located inside the hemispheres. At the end of the unwinding of the entire length of the coil, a new installation of a new coil of tape is made into the hemispheres of the dispenser and the device is again ready for operation.

Compared with known devices, the proposed design has greater convenience and safety of operation and storage. Consumer qualities are much higher than those of known analogues.

The possibility of repeated reproduction of the claimed design results from the method of its industrial configuration, which allows the claimed dispenser-unwinder device to be reproduced on an industrial scale.

Such a combination of versatility, achievement of the possibility of multiple reproduction with relative ease of manufacture in the prototype is not achieved.

Based on the foregoing, we can conclude that the proposed technical solution meets the criteria of "novelty" and "industrial applicability".
