Abstract

The invention relates to packaging production and can be used on textile machines. The aim of the invention is the expansion of technological capabilities by winding a reel of a given density. The device contains a friction drum, a roller and a connecting rod with a bobbin holder attached to it. The drive of the connecting rod changes the force of pressing the reel to the friction drum, depending on the readings of the position sensor of the bobbin holder, made in the form of a cam mounted on the drive shaft of the connecting rod, and the selsyn in contact with it. 2 hp f-ly, 5 ill.

Description

The invention relates to packaging production and can be used on textile machines.

The purpose of the invention is the expansion of technological capabilities by winding a reel of a given density.

FIG. 1 shows the device, a general view; in fig. 2 - the same, side view; in fig. 3 - the mechanism of uncoupling the cartridge; in fig. 4 - bobin holding sensor; in fig. 5 - functional electrical circuit of the device.

The device consists of a housing 1 on which the assemblies of the friction drum 2 and the needle spreader 3 with the drive 4 are mounted, the paddle roller 5 with the shank 6 and the spring 7, the bobbin holder 8 and the tensioner 9 tension the material. The bobbin holder assembly 8 consists of a spindle 10 with a retainer 11 reels, a connecting rod 12, which can be rotated together with a shaft 13, which is connected via a gearbox 14 to an electric motor 15 entering the reel-pressing mechanism to the friction drum 2. The gearbox serves to increase torque developed by an electric motor to clamp the cartridge with the winding thread to the friction drum and retract and supply it when the reel is removed from the spindle. A cam 1b is fixed on the shaft 13, kinematically coupled by the eccentric with the selsyn 17 and forming the bobbin holder position sensor with it. When the connecting rod 12 is deflected, the resolver 17 sends a signal through the clamping force regulator to the electric motor 15, the reverse of which is performed by the command of the positioners 18 and 19.

To fix the bobbin holder 20 on the connecting rod 12, a double-arm lever 21 is mounted hingedly to a pusher 22, at the end of which a roller 23 is fixed, which can be moved along the guide 24 with an oblique support 25. The tensioner 9 of filamentary material consists of a lever 26, at one end of which the directional roller 27 is mounted, and the other is pivotally connected to the float 28, spring loaded 29 and placed in

bath for 30 seconds with a viscous liquid. To limit the stroke of the connecting rod 12, a stop 31 is mounted on the housing. A bipod 32 is fixed to the selsyn 17 axis with a roller 33 at one end and a spring 34 at the other. The cam 16 has a profile 35. When the shaft 13 is rotated and, therefore, the cam 16, the roller 33 rolls the profile 35, turning the axle 17 along the bipod 32. The profile is made in accordance with the angle of rotation of the connecting rod 12.

The device works as follows.

The bobbin holder 20 is threaded onto the spindle 10 and secured with a latch 11. The lever 21 and the pusher 22 with the roller 23 are in the position shown in FIG. 3. The drive 4 of the friction drum 2 and the yarn guide 3 and the electric motor 15 are turned on. The connecting rod 12 rotates and presses the bobbin holder 20 against the friction drum 2 and the roller roller 5, and winding starts after threading. As the diameter of the reel increases, the crank 12 deflects the cam 16 through the roller 33 to the bipod 32. which rotates the axis of the selsyn 17, which through the regulator 36 adjusts the clamping force to regulate the torque of the electric motor 15, thereby changing the clamping force.

After winding is completed, the crank 12 presses the positioner 19, the electric motor 15 reverses and retracts the crank from the friction clutch to the stopper 31. The roller 23 rolls onto the oblique stop 25, moves the plunger 22, which turns the lever 21, depressing the latch 11. Thus, it is removed. reels and installation of the empty cartridge; the reverse of the electric motor 15 is turned on, the connecting rod 12 with the bobbin holder returns to its original position, the thread is bored, and the positioner 18 gives the command to switch on. The winding cycle is repeated.

To compensate for the tension of the thread in the end positions of the yarn threader 3 serves as a tensioner 9. In the extreme positions of the yarn feeder, the thread pulls the spring 29 through the roller 27, and in the middle position the roller returns to its original position. The float 28 in the liquid bath plays the role of a shock absorber.
