Description

The invention relates to light industry, in particular to devices for sewing the edges of upholstered furniture.

A device for sewing the edges of the upholstery of upholstered furniture, ⁵ for example, pillows, containing a platform with a toothed rack along the perimeter, a sewing machine mounted on a carriage kinematically connected with a toothed rare platform and driven plate ¹⁰ clamp mounted above the platform U is known.

However, the known device can not be used for sewing the edges of the skin upholstery complex configuration of products due to the fact that the product in ¹⁵ pro- cession processing is stationary.

The purpose of the invention is the expansion of technological capabilities.

This goal is achieved by the fact that the device for stitching the edges of the sheathing of upholstered furniture, for example, pillows, containing a platform with a toothed rack

around the perimeter, a sewing machine mounted on a carriage kinematically connected to the platform rack and drive plate clamp mounted above the platform, it has a cassette for the product located on the platform, and the plate clamp is spring-loaded, pivotally mounted on the cartridge and has a clamp plate, the contour of which corresponds to the contour of the stitched edge of the product, and the cassette has a latch for fixing the plate clip on the product. The device additionally has a clamp mounted on a cassette and connected to a plate clamp by means of a thrust.

On the phage. 1 shows the proposed device, a general view; ' in fig. 2 is a top view of FIG. one; in fig. 3 - a decorated image of the cassette at the time of compression of the pillow; in fig. 4 - the same, in a constructive version of a curly pillow; in fig. 5 - cassette at the time of laying the pillow with a seam on the end; on phage. 6,924,194

The device comprises a frame 1, on which ^{1 the} bracket 2 and the vertical shaft 3 are mounted with the possibility of horizontal turning. On the bracket 2 is mounted for rotation; about its axis (not shown) platform 4 with a 'smooth coating, having a tooth located outside the perimeter. Chat rail. 5. On the shaft 3 in the lower part there is an operating disk 6 installed on the support 7 for accommodating the operator, and on the upper part of the shaft 3 a carriage 8 mounted, kinematically connected with the rack 5 of the platform;

On the carriage 8 by means of the bracket 12 is mounted the head 13 of the sewing machine, for adjusting the position of which the flywheel 14 is provided.

with screw gear 15. On the platform.

4 is positioned to move freely over the platform 16. The cassette 4 on a rack 17 attached to the bracket 2 is mounted presser drive mechanism 18 with a vertically-rotating shoe ³⁰ pereme- 19. The pressing mechanism 18 may be configured as a screw or rack and pinion drive pair, either in the form of a hydraulic or pneumatic cylinder with a rod. Based on 20 cassettes 16 35

The plate clamp 21 is pivotally mounted, the bifurcated end of which has a clamp plate 22. The plate clamp 21 is spring-loaded with a spring 2 3 upwardly pressed and has a pressure pad 40 on top, the cartridge 16 has a pivotally fixed latch 25 made in the form of a folding latch. with an adjusting screw 26 for fastening the plate clamp 21 to the product 45 45. The device also has an additional clamp 28 mounted on the cassette 16 and connected to the plate Clamp 21 by means of a thrust 29 for compressing the product 27, with seams located in hard-to-reach for processing sites. The contour of the clamping plate 22 of the plate clamp 2 1 corresponds to the contour of the stitched edge of the product 27, and for control of the operation of the device, ₅₅ has a remote control 30.

The principle of the device follow! shy

In the initial position, the shoe 19 of the presser mechanism 18 is raised, the latch 25 in the cassette 16 is opened and the plate clamp 21 and the presser 28 is raised by the spring 23. A soft filler is inserted into the case with the open neck previously stitched from the blanks of facing fabric and the resulting blank is placed in the cassette 16 depending on the type of cushion stitching on the location of the seam. The cassette 16 with the product 27 is placed under the shoe 19 until it is aligned with the pressure pad 24 of the plate clamp 2 1. By turning on the clamping mechanism 18 the shoe 19 is lowered and, acting on the plate clamp 2 1, compresses the pad 2 7.

The clamped 2 is clamped by the locking pin 25, and then the shoe 19 is lifted, and the cushion 27 remains compressed, at which the tension of the fabric is relaxed. The position of the clamp 21 is adjusted with the screw 26. With the shoe raised, the cassette 16 with the product clamped 2 7 acquires the possibility of free movement on the platform 4. The article 27 in the cassette 16 moves towards the sewing head 13, the edges of the fabric are tucked under the needle foot and they are stapled.

Since the product 27 in the cassette 16 is not pressed in the platform 4, in the process of stitching it can, together with the cassette 16, be easily moved and deployed on the platform 4, which is what you have to do when washing the figure pillows. After completion of stitching, the finished product 4 is removed by repeated pressing of the shoe 19 on the plate clamp 21 to open the latch 25, the new preform is laid and the stitching process is repeated.

Achieved in the device, thanks to the use of a cassette for compressing the product, the possibility of free movement and reversal of the product in a compressed state, in which the edges of the fabric blanks are close to each other and their stitching does not cause difficulties, it allows to mechanize the stitching of products of complex configuration , in particular figured furniture cushions.
