SU126398A1 - Device for removing cobs and putting cartridges on spindles of spinning and twisting machines - Google Patents

Description

A device is known for removing the cobs and putting on natrons on the spindles of the spinning and twisting machines, including a lightly movable along the spindles along the guide and conductive rail carriage, a carrier mechanism for removing nightstands, equipped with an endless chain with grippers, and a mechanism for putting on natrons, consisting of a natron hopper, exhaust box, rubber roller and disc shears. This device has an intermittent movement when moving it along the spindles of the spindle, which limits the speed at which the cobs are removed.

The described device for removing the cobs has the ability to continuously move along the rail. In addition, it has a simpler design. The endless chain of the cob removal mechanism is inclined by two sprockets and carries three fork-shaped grips. The mechanism for putting on the airplanes is provided with a pusher with an iron irradiator mounted in the form of a rod with a bevel that guides the cartridge into an inclined position using an angular groove on the rod, and a double arm that interacts with an eccentric sitting on the axis of the upper sprocket of the chain. The cut roller for putting on and besieging the cartridges is cylindrical, inclined and rotated through a flexible transmission from the axis of the upper sprocket. In order to reduce thread breaks, the device is equipped with disc shears for cutting the thread on the cob, located on the axis of the upper sprocket of the endless chain and provided with a guide hook for threading the thread into the scissors.

FIG. 1 shows the device, front view; in fig. 2 - view from the side.

D (126398-2 Carriage /, made of light thin-walled tubes, is moved5 by means of rollers 2 over the relief S mounted along the spindle line of the 4th spinning machine. The rail 5, isolated from the body of the machine, is at the same time conductive bus the current is supplied to the motor 5 mounted on the carriage / to set in motion the mechanism for removing the cobs and the mechanism for putting the cartridges on the spindle 4- The mechanism for removing the cobs 6 from the spindles 4 includes an endless chain 7 mounted obliquely on a two asterisk x 8 and 9. The chain 7 carries three forks 10 of fork shape, located at equal distances from each other.The chain 7 is driven from the electric motor 5 through a gear 11 and a lower sprocket 9. The mechanism also includes a reflector 12 made in the form of a bent a canopy for dropping 4 nightstands 6 removed from the spindles into a container connected to the carriage.

The mechanism for putting the cartridges on the spindle 4 includes a removable cartridge hopper (not shown in the drawing) and an outlet box 13 with a side outlet for the cartridges having spring locking. To prevent possible congestion at the exit of cartridges from the bunker, the window of the box 13 is installed shaking and, with a frame, set in motion with the HELP. And cable 14. The mechanism of putting the cartridges on the spindle 4 is equipped with a pusher 15 and a guide 16 cartridges made in the form of a rod with a bevel , directing the cartridge to an inclined polishing with the aid of an angular groove on the push rod 15, the latter is driven by a two-arm / 7 lever on the axis of the nanopulary 16, interacting with an eccentric 18 fixed on the axis 19 of the upper sprocket 8 of price 7.

A rubber-coated cylindrical roller 20 located obliquely is mounted in the device to put the cartridges on the spindle and upset them. The roller 20 rotates through a flexible transmission from the axis 19 of the upper sprocket 8.

On the axis 19 of the upper sprocket 8 of the endless chain 7, there are disc shears 21 for cutting the thread on the cob 6, provided with a guide hook.

The device works as follows.

The inclined endless circuit 7 is driven by the electric motor 5 through a gearbox 11 w. the lower sprocket 9. The grips 10, which are rigidly placed on the price 7, alternately fit their forks under the lower part of the cobs 6, seize the latter and remove them from the spindles 4. When the cob 6 leaves the spindle 4, the upper part of the cob encounters the reflector visor 12 and falls in the container attached to the carriage. At the same time, the disc shears 21 are set in motion; the guide hook (not shown) turns the thread into scissors 21, which cuts the thread on the cob 6.

Due to the inclination of the chain, when removing the cob, the carriage / along the rail 3 does not move towards the spindle from which the cob 6 is removed, and at the time when the cob leaves the spindle 4, the fork of the next gripper 10 already approaches the bottom of the cob 6 of the next spindle 4, which ensures continuous movement of the device along the spindle line.

Simultaneously with the removal of the cobs 6, the cartridges are put on the released spindles 4. The eccentric 18 fixed on the axis 19 of the upper sprocket 8 through the double-arm lever 17 interacts with the plunger 15, which pushes the next cartridge from the lower part of the outlet box 13. At the exit of the box 13, the plunger 15 due to the presence on it of the angular groove takes an inclined position

and puts the cartridge at an angle of 45 ° to the axis of the spindle 4, holding the leaf spring secured on the box 13 from falling. When the device moves along the spindle line, the end of the free spindle 4 next to it hits the lower base of the yatron, turns it to a vertical position, after which the cartridge is put on on the spindle 4. At the same time, the rotating rubber roller 20 settles the cartridge on the spindle.

Further, the cycle of removing the cobs and putting on the cartridges is repeated on the following spindles.
