Description

Machines for cutting and sewing products, made in the form of a table with the clamping of the workpiece and moving along the table guides of the carriage with an electric motor, on the shaft of which a circular knife is fixed, are known.

The described machine differs from the known ones in that at the same time it provides for the shaking of garments, for example, the outer sides of both trouser legs at a given distance from the line of their low cropped. To do this, two side supports of the holder of crayons are fixed on the carriage, and a spring-loaded roller is mounted, which rolls onto the clamp and lowers it onto the bushes.

In order to mechanize the carriage movement in the forward and reverse directions, a reversible electric motor is used in this flock, connected by gear transmission to the rail, which is attached to the table guides, switched and switched off by two end switches interacting with the carriage and connected to the magnetic starters of this electric motor.

For the convenience of sharpening a circular knife, the carriage is provided with a lever carrying a rotatable mounted abrasive wheel.

FIG. 1 shows a machine, side view; in fig. 2 is a part of the machine tool. H, in a partial section along the line of the ABEC in FIG. one; in fig. 3 - his electrical circuit.

The described machine is made in the form of a table / and carriage 2. The table is provided with a clamp 3 attached to it by means of a hinge 4 and intended to press together folded sewing goods, for example, trouser legs (not shown) on the table (on the drawing is not shown), with window 5 and guides 6 fastened to the table by means of 1 of 7 and a cut; 1 of the pins 8.

No. 126821-2 -

The rails 9 of the carriage 2 are mounted on the guides, carrying a reversible electric motor 10 with a disk knife 13 mounted on its shaft 11, spring-loaded prrussine 12 for cutting low trousers interacting with a fixed knife 14 of the table. The opposite end of the motor shaft is connected to a bevel gear transmission 15 and a worm gear box 16 with a drive gear 17 mounted on a carriage coupled to a fixed rail 18 attached to the guide channel bars.

To shuffle low trousers on the outside, at a given distance from the trim line, two carriages are mounted on the carriage by means of brackets 19 and 20; inline holders 21 and 22 of crayons 23. To automatically lower the spring loaded roller 24 onto the trouser-mounted legs on the carriage. rolling on the clamp. For sharpening the disk knife on the carriage, the lever 25, carrying a rotatable abrasive wheel 26, is fixed.

To prevent it from lifting, the carriage is equipped with two pads 27 carrying spring-loaded rollers 28 running around the channel 7. In order to mechanize the movement of the carriage in the forward direction along arrow D and the return direction, there are two limit switches 29 and 30 that interact with carriage.

The start-up motor is carried out by the start button 31, turning it on via the magnetic starter 32 and its contacts 32-1. For direct rotation and movement of the carriage along arrow D. In the extreme position, the carriage through the contacts 30-1 switch 30 turns off the magnetic starter 32, stopping the motor And at the same time, contacts 30-2 of this switch turn on another magnetic starter 33, which activates the motor to return rotation and movement of the carriage but the arrow, up to the stop in switch 29. With its contacts 33-1, this switch yuchatel your contacts 29-1 turns off the magnetic contactor 33 and the motor stops in the initial position of the carriage. The emergency shutdown of the electric motor is accomplished with a 34 "stop. The magnetic starter 32 is equipped with contacts 32-2 self-powered and the locking contacts 32-3 of another magnetic actuator 33. The latter is equipped with self-feeding contacts 33-2 and locking contacts 33-3 of the first magnetic actuator.

The action of the machine is as follows. The trouser legs are sutured, laid on table 1, after which the electric motor is started by the start button 31. The electric motor 10 of the carriage moves it along arrow D. A roller 24, rolling on the presser 5, lowers it onto the trousers, the disk knife cuts off the low trousers and at the same time both crayons 23 shade the trousers outside at a predetermined distance from the cutting line. At the end of the carriage stroke, the switch 30 switches the motor to reverse rotation, the carriage moves in rapid motion back in arrow E and at the end of the stroke the roller 24 releases the presser 3, and the switch 29 turns off the electric motor, which ends the process of trimming and shredding low trouser legs.

Subject invention

Claims (2)

1. A machine for cutting garments ;, made in the form of a table with a clamp for the workpiece and a carriage with an electric motor moved along table guides, on the shaft of which a disk knife is fixed, in order to ensure simultaneous deformation, for example, the outer sides of both trouser legs at a predetermined distance from the cut lines are low, two spring-loaded holders (me.1kch) are mounted on the carriage, and an integral roller is mounted on the carriage, which rolls onto it. 2. The form of the machine according to claim 1, about HI, and so that, in order to mechanize the movement of the carriage in the reverse direction, it uses a reversible electric motor connected with a strip with a strip to the gear , fixed on the guide table, and switched and switched off by two limit switches interacting with the carriage, included in the circuit of magnetic starters, 3, The form of the machine, but pp. 1 and 2, is designed in such a way that, in order to increase the convenience of sharpening the disk knife, the carriage is equipped with a lever that carries a rotary mounted abrasive wheel.
