Description

A known machine for adjusting garments, including a table, a mechanism for pressing and holding the workpiece and moving the carriage with a knife along the table guides.

The disadvantage of this machine is the absence in it of the required number of profiles of curved lines, which are used to equip the corresponding product styles, and the replacement of some profiles with others requires the presence and replacement of a number of parts, which reduces the productivity of the machine.

The described machine provides for the adjustment of parts of garments, for example, bead and bottom, of any styles and sizes, which significantly increases the productivity of the machine. For this, the mechanism for pressing and holding - the workpiece is made in the form of upper and lower flexible rulers, hingedly connected with screw adjusting rods, and for adjusting the degree of pressing by the rulers of the editable edge of the product, the machine is equipped with a mechanism for additional clamping, made in the form of a spring-loaded pull with a pawl at the end, a cam interacting with a sleeve mounted coaxially with the thrust and fixed on the frame of the upper ruler of the second dog, interacting with the dog of thrust.

The drawing shows a circuit for setting garments.

The machine for fitting the products includes a table / and a mechanism for clamping and holding the workpiece, made in the form of upper and lower flexible bars 2 and 5, and for the convenience of filling the mounted products between the rulers, the upper ruler 2 rises up and locks in this position at an angle of 50 -75 °. The 2 L 3 rulers are pivotally connected with the adjusting screws 4, designed to create a curvilinear contour in accordance with any cut and size, for example.

No. 144794- 2 sides and bottom outerwear. The adjustment of the machine from one type of curve to another is carried out with the help of grids 4 and does not require the replacement of any parts of the machine. Rulers provide a clip for the editable edge of the product and are at the same time guides the carriage with a knife. The carriage consists of a housing 5, a fixed knife 6 of a rotating multi-blade knife 7, a driving roller 8, an upper roller 9 and a system of 10-wheelers receiving rotation from a reversing motor // through a flexible gear 12. During operation, the carriage moves along rulers 2 and 3, providing an adjustment of the curvilinear contour of the product. In order to shorten the processing cycle, the trim is performed bilaterally without idling the carriage. In connection with this, the multi-blade rotary knife 7 has a double-sided sharpening.

To eliminate the failure of the product to be installed, down between the rulers and the edge of the table, there are special valves in the table cover that eliminate the gap between the edge of the table and the rulers.

To regulate the degree of pressing with rulers 2 and 3 of the equipped edge of the product, the machine is equipped with a mechanism for additional clamping, which consists of an upper pawl 13 fixed on the frame 14 of the upper ruler 2 and a pawl 15 which is hingedly connected with spring loaded pull 16. Coaxially on , the sleeve 17 sliding along the grip 16 is retarded, which is affected by the cam 18 controlled by the handle 19. When the cam 18 does not press on the sleeve 17, the dog 15 is lifted up by the action of the spring 20 and the spring 21 is retracted yku 2. By turning the handle 19, the cam 18 presses against the sleeve 17, lowering the pawl 15 connected to the pawl 16. The draft type 15, riding straight on the roller 22, it is withdrawn towards the pawl 13 and locks the latter. Upon further lowering of the sleeve 17, the dog 15, interacting with the dog 13, creates the necessary clamp of the upper ruler 2 to the lower ruler 3.

During operation, the maschine raises the upper ruler 2 and imposes a fixed edge of the product on the lower ruler 3. Then, lowering the upper ruler 2, create a clip on the edge of the product and turn the handle 19 to provide the necessary additional clamping of the upper ruler 2 to the lower ruler 3.

Including the trigger button, the carriage is activated, the knife 7 of which, rotating, sets the edge of the product along a curvilinear contour formed by flexible rulers 2 and 5 with the help of adjustment bars 4.

After adjusting, all mechanisms of the rulers return to the initial position, the upper line 2 is lifted and the finished products are removed.

The industrial utility of this proposal has been confirmed by the Central Research Institute of Screw Industry, according to which the proposed machine allows, without replacing any parts, to fit the sides and bottom of outerwear to a large number of styles and sizes with different configurations of curves.

Subject invention

A tool for fitting garments, including a table, a mechanism for clamping and holding the workpiece and a carriage with a knife that is moved along table guides, in order to increase the productivity of the machine and to provide equipment for the parts of garments, for example, bead and bottom, any styles and sizes, the mechanism for clamping and holding the workpiece is made in the form of upper and lower flexible rulers, hingedly connected to the screw adjusting rods, and for adjusting the degree of pressing the ruler and osnoravlivaemogo edges of the product machine is provided to further clamp designed as a spring-loaded rod with the pawl on the end of the cam interacting with the sleeve mounted coaxially with the draft type, and fastened to the upper frame-it line of second pawl interacting with a pawl rod.
