Description

The invention relates to equipment used in the clothing industry, in particular for the production of mattresses.

A known machine for picking mattresses [1], including a drive, a mechanism for raising and lowering a needle with a valve, a presser foot, a yarn spreader, a cassette with picks and a transporting device consisting of a ring rotated by a dog, a roller applying glue to the surface of the ring to hold the pick on ring.

The main disadvantages of the above machines are:

- the use of manual labor in the preparation of the lower pick;

- the need for continuous cleaning of the ring from adhesive residues;

- when the glue dries, the picks become stiff, which affects the quality of the mattresses;

- the absence of a stopper and ring fixation is the cause of a frequent malfunction of the machine, which leads to breakage of the needles.

The present invention is directed to solving the technical problem of eliminating these disadvantages:

- reduction of manual labor;

- improving the quality of products and the reliability of the machine;

- reducing the cost of maintenance and repair of equipment.

The technical result, which consists in solving these drawbacks in a machine for picking mattresses, including a drive, a mechanism for raising and lowering the needle with a valve, a presser foot, a thread spreader, a cassette with picks and a conveying device consisting of a ring rotated by a dog, a roller applying glue to the surface rings to hold the pick on the ring, is achieved due to the fact that the machine is equipped with a roll drive for pick braid, a mechanism for cutting the lower pick, clamp and limiter, and the picking device for feeding the lower pick is made in the form of a rim aligned with a disk on which the teeth of ratchets of the opposite direction are cut into two rows in diameter, while the needles are fixed to the rim along the edges on both sides of the longitudinal grooves and, additionally, the diameter of the transverse closed , and along the end open grooves.

The invention is illustrated by drawings, where:

- figure 1 schematically shows a General view of the machine;

- figure 2 is a view a in figure 1.

The machine for picking mattresses comprises a frame 1 on which a drive 2 is mounted, a needle bar 3 with a needle 4, a presser foot 5, a thread spreader 6, a roll accumulator 7 for a braid 8, a latch 9, a limiter 10, an eccentric 11, a pedal 12 that interacts with the spring 13.

In addition, on frame 1 there are:

- a transport device 14 of the lower pick 15, which is a rim 16, combined with a disk on which the teeth of the ratchets 17, 18 are cut in two rows in different directions, while the needles 19 are fixed on the rim 16 along the longitudinal grooves on both sides and transverse closed, and at the end open grooves, respectively, B, C;

- a mechanism for cutting 20 of the lower pick 15, consisting of a knife 21, a holder 22, mounted on a rotary axis 23, a pressure plate 24, fixed to a fork 25, freely mounted on the rotary axis 23 and the spring 26.

A lever 27 is freely mounted on the axis of the rim 16, on which the dog 28 is fixed, and which is connected to the pedal 12 through a system of levers 29.

The main working mechanisms of the machine are controlled through the clutch 30 by means of an eccentric 11. The frame 1 is made in the form of a table with a plate 31 on which the workable mattress 32 is laid. The upper peak 33 is laid on the mattress 32 manually.

Machine for picking mattresses works as follows.

Threading from the bobbin to the yarn spreader 6, the braid 8 from the roll accumulator 7 to the rim 16, is threaded by pricking it on the needles 19. In the initial position, the pedal 12 is in the upper position by means of the spring 13 and the lever system 27, 29. At the same time, the dog 28, being in contact with the ratchet 17, engages with the upstream tooth of the ratchet 17, and the limiter 10, relying on the lever 28, is out of engagement with the ratchet 18.

Not including the drive 2, by pressing the pedal 12 through the system of levers 27, 29 by means of the dog 28 and the ratchet 17, the rim 16 moves to the stop of the stopper 10 with the ratchet 18 (Fig. 2).

In this case, the braid 8 enters the zone of the mechanism for cutting 20 of the lower pick 15 and is held on the conveying device 14 by means of needles 19, a pressure plate 24 fixed to the fork 25 and the spring 26.

After that, the machine is ready for use.

On the plate 31 of the frame 1, the processed mattress 32 is laid. The upper peak 33 is laid on the mattress 32 in the flashing zone under the tab 5 (figure 1, 2).

The drive of 2 cars turns on.

By pressing the pedal 12 occurs:

- the movement of the rim 16 to the stop of the stopper 10 with the ratchet 18 (figure 2), which is provided through a system of levers 27, 29 by means of a dog 28 and ratchet 17;

- supply of the lower pick 15 to the firmware zone, which is held on the rim 16 by needles 19;

- actuation of the clutch 30 and the inclusion of the clown 11. When this is done:

- lowering the foot 5 on the upper pick 33 and the mattress 32;

- moving the latch 9 into the open groove "B" of the rim 16, ensuring the fixation of the conveying device 14;

- rotation of the axis 23, on which the mechanism for cutting 20 of the lower pick 15 is fixed, consisting of a knife 21 and a holder 22, the knife 21 of which, passing through the groove of the pressure plate 24 and the transverse groove "B" of the rim 16, cuts the braid 8, thereby forming bottom pick 15;

- lowering the needle bar 3 with the needle 4, which pierces the mattress 32 with picks 15, 33 through it, grabs the thread from the yarn spreader 6 and returns to its original upper position, while fixing the upper and lower picks 15, 33 to the mattress 32.

Then, the needle bar 6, at the command of the eccentric 11, is rotated 180 ° and again lowered down, the needle 4 grabs the thread from the yarn spreader 6 and returns to its original position. This completes the fixing cycle of picks 15, 33 on the mattress 32.

In this case, the retainer 9 and the mechanism for cutting 20 of the lower pick 15 are returned to their original position.

Next, the mattress 32 is manually moved along the plate 31 by a certain step, and when you press the pedal 12, the process of picking the mattress 32 is repeated.
