RU2396387C1 - Measuring-inspection machine with device of fabric orientation along centre - Google Patents

Abstract

FIELD: textile, paper.

SUBSTANCE: invention relates to light industry and measuring-inspection machine with device for central orientation of fabric. Machine includes winding device, screen for visual sorting and unwinding device. Winding device is arranged in the form of movable carriage, which moves along guides of frame, transporting shafts with independent adjustments of shaft position in horizontal and vertical plane are installed into seats of carriage. Central orientation of fabric is done by sending a signal to stepped motor by optical sensor arranged on metering-inspection table. Pulse from sensor identifies direction of pulley rotation in stepped motor, which interacts with carriage via toothed gear and rack.

EFFECT: invention makes it possible to minimise consequences of fabric deformation in longitudinal direction, using machine with one drive, and also provides for more stable contact of fabric roll with transporting shafts.

Description

The invention relates to light industry and can be used to control textile materials and the formation of fabric into a roll in the preparatory production.

Known reject measuring machine PS-1 / Franz V.Ya. Equipment for sewing production. 2005 /, including the unwinding fabric device 1, into the trough of which a roll of material 2 is loaded, the fabric passes through the transport rollers 3 and 4 of the unwinding device, the fabric is smoothed out and the folds are removed during the movement. After this, the fabric enters the screening area on an inclined screen for visual screening 5. Then the fabric enters a group of rollers located after the measuring device and providing the necessary fabric tension. The fabric is wound into a roll by means of a winding device 6. The winding is carried out due to friction between the conveying roller and the roll of fabric (figure 1).

The disadvantages of this machine are: a significant deformation of the fabric in the longitudinal direction during its interaction with the working bodies of the machine; the formation of uneven edges of the fabric in the roll; the complexity of loading and unloading operations; inconsistency of contact between the material and the conveyor shaft.

An object of the invention is to eliminate uneven edges in a roll of rewound fabric by ensuring the position of the fabric relative to the center with a given deviation.

This object is achieved in that the measuring and rejecting machine with the device for orienting the fabric in the center includes a reeling device, a screen for visual screening and an unwinding device, characterized in that the reeling device is made in the form of a movable carriage moving along the frame guides and set to the carriage seats transporting shafts having independent adjustment of the shaft position in horizontal and vertical planes, this design allows orientation Central web by supplying a signal to the stepper motor by an optical sensor located on Surveying razbrakovochnom-table; the pulse from the sensor determines the direction of rotation of the pulley of the stepper motor, which interacts by means of a gear gear and a rack with a carriage.

The device is illustrated in figure 2.

The design of the reeling device includes a gear motor 7 with a chain gear 8, 9, 10, 11, which transmits rotational motion to the transporting shafts 12 and 13 installed in the seats of the carriage 1. The carriage 14 has the ability to move in the longitudinal direction along the guides of the frame 15 and receives movement from a stepper motor 16 through a gear wheel 17 and a rail.

The work of the proposed device is as follows: a roll of fabric is installed in the guides of the rolling pin rotating in the supports. The fabric passes through the guide rollers and enters the viewing screen, where the processes of material sorting, the determination of the coordinates of the surface defects of the fabric and the measurement of geometric characteristics take place. Then the fabric with the help of guide rollers is leveled and wrinkles are eliminated. Next, the fabric enters the reeling device and is wound on a rolling pin 18, which is held in the guides 19. The position of the rolling pin is controlled by the offset of the link 20 along the axis of the guides. The provision of the required pressing of the roll to the transporting shafts 21 is provided by the loads. The movement of the fabric is carried out due to friction forces arising between the transporting shafts 12, 13 and the roll of fabric. The transporting shafts 12, 13 are driven by a chain transmission consisting of driven sprockets 9, 11, a chain 10 and a drive sprocket receiving movement through a gearbox 7 from an electric motor. It should be noted that the transporting shafts 12, 13 have independent adjustment of position in the horizontal 23, 24 and vertical planes 22, which eliminates the skew of the fabric. The electric motor, gearbox 7 and transporting shafts 12, 13 are mounted on a movable carriage 25, which moves in the desired direction depending on the direction of rotation of the gear 17 of the stepper motor 16, which engages with a rail rigidly mounted on the movable carriage 25.

Thus, the proposed device allows to achieve the goal.
