Description

one

The invention relates to the sewing industry and can be used to automate the embroidery process, for example, on an MV “5O embroidery machine.

A device for moving the material on an embroidery machine is known, which contains a cam program carrier kinematically connected with the main shaft of the machine and a summing mechanism, the follower link of which is associated with the material holder and the drive carrier with the program carrier. In this case, the summing mechanism is a system of levers.

Such a device does not provide the possibility of obtaining a wide range of patterns.

In order to expand the technological possibilities in the proposed device, the leading link of the summing mechanism consists of a central hollow shaft and a coaxial shaft coaxially located in it, the central shaft being kinematically connected with the main shaft of the machine, and the flood shaft with a program carrier. With this kinematic

The connection is made using bevel gear pairs.

On the FPG, 1 is shown the kinematic diagram of the device; in fig. 2 - options for contour lines.

On the main shaft 1 of the embroidery machine, a worm is rigidly set to 2, which is engaged with a worm wheel 3. A worm wheel 3 is located on the upper end of the vertical shaft 4, at the lower end of which are bevel gears 5 and 6. Gear 5 is engaged with a bevel gear 7, rigidly mounted on a horizontal shaft 8. On the shaft 8 there is a set of cams — a program carrier 9. Gear 6 is connected with a bevel gear 10, planted on the end of a horizontal shaft 11, at the other end of which there is a bevel gear and gear 12. 12. The gear 12 is engaged with a bevel gear 13, seated on a vertical central hollow shaft 14. At the other end of the central shaft 14, a bevel gear 15 is firmly seated and meshes with the gear 16

The rod 17, pressed against one of the cams 9 by a spring 18, is rigidly seated on a horizontal shaft 19, with the possibility of periodically shifting along the shaft to change the engagement with the program carrier 9 The shaft 19 ends with a bevel gear

20 meshed with bristles

21, mounted on the drive shaft 22. The drive shaft 22 passes inside the vertical central hollow shaft 14 and is formed by an L-shaped process, on which a rigid gear 16 is mounted, transmitting movement to the summing bevel gear 23.

The device works as follows.

Movement from the main shaft 1 through the worm gear pair 2, 3, vertical shaft 4, bevel gear pair 5, 7, horizontal shaft 8 is transmitted to program carrier 9 From shaft 4 rotation through bevel gear pair 6, 1 O, horizontal shaft 11, another bevel gear pair 12, 13 is transmitted to the vertical central field of the shaft 14, and therefore also to the jaws 15. When the program carrier 9 rotates via the rod 17, presses the spring 18 to one of its cams, through the shaft 19 and the conical gear pair 20, 21 the vibrations are transmitted to the drive shaft 22.the drive shaft 22 is transmitted

a conical gear 16 which is rigidly mounted on its L-shaped process, which also receives rotation from gear 15. Then the total movement from gear 16 is transferred to summing conical gear 23, which transfers it to the loop-forming and transporting mechanisms of the embroidery machine according to a well-known pattern. To change the pattern, it is necessary to move the rod 17 along the shaft 19 and connect the program carrier 9 to another cam.

The device can be used for trimming capes, slivers, skullcaps, panamas and similar items.
