Description

The utility model relates to devices for rewinding rolls of tape materials, for example bandages, and can find application in the manufacture of rubber products.

Known rewinding machines for winding into a roll of tape materials (for example, patents RU 2124465 C1, filing date 11/26/1997, published 01/10/1999; RU 2513130 C1, filing date 10/19/2012, published 04/20/2014 ) containing a roll equipped with a braking mechanism for the initial roll with a fixing unit for the initial roll of tape material, a winding unit with a sleeve fixing unit, a drive and a drive switching mechanism with a pedal located under the winding unit. In accordance with patent RU 2513130 C1, the unit for fixing the initial rolls of tape materials is made in the form of a spring interacting with the drum connected to the preload device, and the peals and the winding device contain cantilevers installed in the bearing unit of the rod, the unit for fixing the sleeve is made in the form of a bead installed with the ability to move relative to the rod and interacting with a nut mounted on the threaded end of the rod, and an additional fixing unit for the roll in the form of a pressure roller is installed. In accordance with patent RU 2124465 C1, the roll contains a lifting unit for the initial roll of tape material, and the winding unit comprises a sleeve placement device, which is made in the form of a winding rod, one end of which is pivotally mounted in the first pillow block bearing and kinematically connected to the drive. The sleeve fixing unit is made in the form of a split cup, the open end of which is located with the possibility of grasping the other end of the rod, and the opposite end is rigidly connected to the rod, fixed in the second support bearing with the possibility of movement in the longitudinal direction.

The disadvantages of the known rewinding machines for winding into a roll of tape materials include the low quality of winding the material at the ends of the roll, due to the lack of alignment of the material in the direction of winding in the transverse plane. In addition, the rewinding machine, known from patent RU 2124465 C1, has a complex drive design for raising and lowering the roll, because it is designed for large masses and diameters of wound rolls. The disadvantage of the rewinding machine according to the patent RU 2513130 C1 can also be attributed to the fact that tight winding of the rolls on it is achieved not by the design features of the machine, but by pressing on the drive pedal.

In addition, the design of the known rewinding machines has great complexity and, as a consequence, low reliability and complexity in maintenance. So, the use of interchangeable pulleys according to the patent RU 2513130 C1 leads to difficulties in servicing the machine. The disadvantage of this machine is also the presence of a variator, which must be manually adjusted to match the speeds of the wound and wound materials.

A device for rewinding tape material is known, comprising means mounted in the housing for fastening unwinding material, mounted for free rotation, means for fastening winding material, fixed in supports with free rotation and kinematically connected to the drive, a first guide shaft rigidly fixed in the housing and installed behind the means for fastening the unwinding material in the direction of movement of the winding material, the clamping shaft, installed ny to come into contact with the means for fastening material to be wound. The device is equipped with a second guide shaft rigidly fixed in the housing and installed behind the first guide shaft in the direction of movement of the wound material, a friction shaft rigidly fixed in the housing and installed behind the second guide shaft in the direction of movement of the wound material, a cutting shaft, a launch unit kinematically connected with drive and with means for fastening the wound material, a braking unit kinematically connected with the clamping shaft (certificate for utility model RU 2 6543 U1, priority June 20, 2002, published December 10, 2002).

A disadvantage of the known device for rewinding tape material is the difficulty in manufacturing due to the large width and mass of the paper web of the roll.

A device for rewinding long material is known, comprising an extended conveyor with two conveying means located at a distance from each other and connected through an inclined sliding surface, a support unit for placing a roll located on one of the conveying means inclined to the latter (EP 1990297 B1, priority 05/05/2007, published on 02/13/2013).

The disadvantages of the known device for rewinding long material include the unreliable installation of the roll on the conveyor, since the roll is not located on the axis, but under its own weight, which can lead to a break in the material, as well as the complexity of the design, due to the need to synchronize the two conveying means.

The closest technical solution is a rewinding machine for winding into a roll of tape materials containing a roll, pulling shafts, a cartridge case with a device for feeding them to a winding device, including two centered winding shafts, and a clamping shaft mounted on one end of the lever, the other end of which pivotally mounted on the axis, while the lever is equipped with a means of moving its axis relative to the centers of the winding shafts (patent SU 1180337 A, filing date 03/01/1984, published 09/23/1985).

The disadvantage of the closest analogue is that it has great difficulty in manufacturing associated with the large width of the rewound paper web and the large mass of the roll, as well as the complexity of the eccentric mechanism with a membrane valve and the mechanism of raising and lowering the roll to install it on the roll.

A technical problem, the solution of which is provided by the claimed utility model, is the creation of a device for rewinding a tape, the design of which can withstand breaking load up to 300 kgf, increase the density of the winding tape material (bandage), eliminating the specific defects of the winding of the bandages, expressed in the presence of folds in them, which in turn, it can further lead to a deterioration in the quality of production of rubber products, in particular rubber sleeves, and also allows you to get a wound roll with smooth ends with the possibility of wetting with water. The technical problem of this utility model is also the creation of a simpler and more reliable design of the rewinder, which, due to the simple mounting of the coil on the rod and the simple design of the lever mechanism of the pressure roller, the use of the foot pedal and the guide roller on the bypass finger, reduces the time for reinstalling the coils and increases productivity .

The technical result obtained by using the inventive utility model is to improve the quality of the winding of the roll, which is expressed in increasing the density of the winding of the material, in the absence of folds of material in the roll and in obtaining a roll of material with smooth ends.

The technical result is achieved by the fact that in the device for rewinding tape material containing a roll stand, according to a utility model, the device further comprises a stand with a drive equipped with a rod for mounting the coil, a first roller rigidly mounted on the bypass pin of the rack, two fingers located on both sides from the first roller, the second roller mounted on a rack above the first roller and behind it on the double-lever mechanism with the possibility of radial movement relative to the coil, while the double-lever the mechanism is mounted in a bearing support in the upper part of the rack and is arranged to move along a guide connected to the upper part of the rack with a cantilever plate, and a locking mechanism installed in the upper part of the rack under the double-lever mechanism.

The device for rewinding the tape material may be provided with a bath for wetting the material installed below the coil.

The tub of the tape rewinder can be equipped with a chipper to drain the wetting agent.

The device for rewinding the tape material can be equipped with a pedal for turning on the drive.

The present useful model is illustrated by drawings (Fig. 1-2), an example of a device for rewinding tape material on which, however, is not the only possible, but clearly demonstrate the possibility of achieving the claimed technical result.

The figure 1 shows a side view of the device for rewinding the tape material, figure 2 is a front view of the device for rewinding the tape material.

According to a utility model, the device for rewinding the tape material comprises a roll-out rack 1 and a rack 2 with a drive 3. The rack 2 is provided with a rod 4 for installing a coil (Fig. 1, 2). The device for rewinding includes a first roller 5, rigidly mounted on the bypass finger 6 of the rack 2, and two fingers 7 and 8 located on both sides of the roller 5 (Fig. 1 and 2). The device for rewinding includes a second roller 9 mounted on a stand 2 above the roller 5 and behind the roller 5 on the double-lever mechanism 10 with the possibility of radial movement relative to the coil (Fig. 2). The double-lever mechanism 10 is installed in the bearing support 11 in the upper part of the rack 2 and is arranged to move along the guide 12. The guide 12 is connected in the upper part of the rack 2 with the cantilever plate 13. The device is also equipped with a locking mechanism 14 (Fig. 1) for moving the roller 9. The locking mechanism 14 is installed in the upper part of the rack 2 under the double lever mechanism 10.

If necessary, the device may include a bath 15 for wetting the material, mounted below the coil. In this case, the bath 15 can be equipped with a chipper 16 for water drainage (Fig. 2). The device for rewinding the tape material can also be equipped with a pedal 17 for turning on the drive 3 (Fig. 2).

Roller 5 serves to guide and tension the tape material (bandage), which is unwound from a roll installed in the expansion rack 1. Roller 9 is used to clamp the bandage, which is wound on a reel mounted on a rod 4.

A device for rewinding tape material works as follows.

After installing the coil on the rod 4 and installing the roll of the bandage on the roll stand 2, the bandage is inserted through the fingers 7 and 8 and the roller 5 onto the rod 4 under the second roller 9. Pressing the foot pedal 17 starts rewinding, during which the worker directs the bandage without effort to the roller 5, then the bandage enters the coil of the rod 4 under the roller 9, which presses the bandage and forms a tight roll of bandage.

The density is achieved due to the pressure roller 9, which presses on the bandage with its mass and each turn on the coil is compressed with a certain force. The density of the winding of the bandage and the direction of the bandage allows you to wind coils with a diameter of up to 700 mm, which reduces the technological time for reinstalling the coils. The bandage is pre-stitched on a sewing machine, and if the package has a bandage length of 150 m, then the stapled and rewound bandage in the spool is up to 580 m. .
