When carrying out manual marking off on the cloth surface, generally fix the cloth monolithic in the workstation for utilizing swager to construct, at this moment, in order to avoid drawing the cloth excessively and arouse the shrink of drawing off the back image area of accomplishing when the swager constructs the fixed cloth, generally only roughly fix the cloth, by the marking off staff one hand pressure on the cloth, the work of marking off is accomplished to the other hand. One hand is pressed on the cloth, so that on one hand, wrinkles can be flattened to keep the marking position smooth, and on the other hand, the phenomenon that the marking accuracy is influenced due to the fact that the cloth is inclined under the driving of a marking pen is avoided. The existing full-automatic marking device generally directly marks out the stretched cloth, so that the problem of excessive pulling of the cloth is easily caused, the cloth is not stretched after marking out, the cloth is found to retract to the original size, and an image formed by marking is shrunk accordingly. Even if the image is enlarged appropriately according to the degree of pulling of the fabric at the time of scribing, the degree of stretching is likely to be different depending on the force applied to the fabric in each direction, and the scribing accuracy is eventually affected.

According to the scheme, the material pressing mechanism is used for fixing the cloth on the workbench, and the material pressing mechanism keeps the overall relative flatness of the cloth so as to guarantee the matching degree of planned marking and actual marking from the overall angle. An X-Y axis displacement unit is arranged above the workbench, and the scribing pen and the flattening unit are driven by the X-Y axis displacement unit to translate along the X axis and the Y axis to complete scribing actions.

Example 1:

a garment fabric positioning and marking device as shown in fig. 1 and fig. 2 comprises a working table 1 for placing fabric, and a material pressing mechanism 4 for fixing the cloth on the workbench 1, wherein an automatic marking mechanism is arranged above the workbench 1 and comprises an X-Y axis displacement unit 2, and a scribing pen 5 and a flattening unit 3 fixed on the X-Y axis displacement unit 2, wherein the flattening unit 3 comprises a telescopic cylinder 301, and a plurality of flattening members 305 which are in transmission connection with the output shaft of the telescopic cylinder 301 and contact with the surface of the cloth, the scribing pen 5 is telescopically connected with the output shaft of the telescopic cylinder 301 and is positioned at the central position enclosed by the flattening pieces 305, the telescopic cylinder 301 drives the flattening piece 305 to rotate and reset after being lifted up, so that the cloth in the enclosing range of the flattening piece 305 is pulled outwards.

The working principle is as follows:

the preparation work before scribing is as follows, the cloth is placed on the workbench 1, the material pressing mechanism 4 is used for fixing the whole cloth, the whole cloth is enabled to be static relative to the scribing pen 5, the flattening piece 305 of the flattening unit 3 is in surface contact with the cloth, the flattening piece 305 is driven by the telescopic cylinder 301 to move, and the part of the cloth in contact with the flattening piece 305 and the part enclosed in the center by the plurality of flattening pieces 305 are enabled to be kept flat. During scribing, the X-Y axis displacement unit 2 drives the flattening unit 3 and the scribing pen 5 to move synchronously, the contact part of the scribing pen 5 and the cloth is always positioned at the center of the flattening piece 305, the cloth in the center enclosed by the flattening piece 305 is flat due to the adjustment of the flattening piece 305 before scribing, the pressure applied to the cloth by the flattening piece 305 is proper, and the flattening unit 3 can always keep the flatness of the cloth passing by the scribing pen 5 in the scribing process. In addition, the control of the telescopic cylinder 301 to the flattening piece 305 can also be on the basis of pulling the cloth, including controlling the action of the flattening piece 305 to be away from and close to the cloth, combining the connection of the telescopic cylinder 301 and the scribing pen 5, the telescopic cylinder 301 can control the flattening piece 305 and the scribing pen 5 to be away from the cloth, and when discontinuous scribing is required or after the scribing is completed, the scribing pen 5 can be timely removed to avoid forming a messy line.

It should be noted that, the output shaft of the scribing pen 5 and the telescopic cylinder 301 is telescopically connected, except the fact that the scribing pen 5 can be controlled by the telescopic cylinder 301 to perform lifting motion, the telescopic meaning of the scribing pen 5 also means that the scribing pen 5 can be installed by an elastic component, and the scribing pen 5 is ensured to be always in contact with the surface of the cloth by elastic constraint, for example, in the embodiment, the maximum telescopic stroke of the telescopic cylinder 301 can be set to be 5mm, the effective telescopic stroke of the scribing pen 5 is 3mm, and the elastic constraint is utilized to enable the scribing pen 5 to have a reciprocating motion range of 3mm in the scribing process, so as to overcome the problem that the scribing pen 5 does not continuously scribe when the surface of the cloth is uneven; when the scribing is finished, the telescopic cylinder 301 drives the scribing pen 5 to lift upwards, and the pen point of the scribing pen 5 can be naturally separated from the surface of the cloth to avoid the problem of redundant scribing.

The selection of the specific parameters is only one parameter setting which satisfies the continuous marking and avoids the marking pen 5 from abnormally contacting the cloth after the marking is finished, and other parameter settings can be selected by the skilled person under the condition that the above conditions are satisfied.

It should be noted that the X-Y axis displacement unit 2 described in the present application is a mechanism for driving the scribing pen 5 and the flattening unit 3 to move, and the movement includes a translational movement along the X axis and the Y axis, and the movement along a certain axis alone forms a linear trajectory, and the movement along the X axis and the Y axis forms an oblique or arc trajectory. The X-Y axis displacement unit 2 may be of any commercially available structure, and the mechanism for controlling the movement of the X-Y axis displacement unit 2 may be a numerical control device.

Example 2:

It should be noted that fig. 3 and 4 only show a state of the flattening unit 3 during scribing, and the state of the flattening unit 3 and the distance between the flattening member 305 and the surface of the table 1 in fig. 1 and 2 are only schematic and do not represent the actual state of the apparatus. According to the state of the flattening unit 3 as illustrated in fig. 3 and 4, when the flattening member 305 needs to move to flatten the cloth near the scribing pen 5, or the pressure applied by the flattening member 305 to the cloth needs to be adjusted, the telescopic cylinder 301 drives the output shaft thereof to shorten, the transmission disc 307 moves upwards, since the two ends of the first link 304 are respectively hinged with the transmission disc 307 and the flattening member 305, the first link 304 rotates to enable the end of the flattening member 305 far away from the scribing pen 5 to be tilted upwards, while the rotation of the first link 304 enables the cam 308 to rotate through the second link 303, and the telescopic link 306 shortens to enable the end of the flattening member 305 near the scribing pen 5 to be pressed downwards. The movement of the flattening piece 305 is integrated to form a compound movement that one end of the flattening piece 305 close to the scribing pen 5 is pressed downwards, and meanwhile, the end of the flattening piece 305 close to the scribing pen 5 is taken as a circle center, and the flattening piece 305 rotates integrally to enable one end of the flattening piece 305 far away from the scribing pen 5 to tilt upwards, which is similar to the action of manually smoothing the surface of the cloth.

In this embodiment, preferably, in order to control a movement stroke of the end, close to the scribing pen 5, of the flattening member 305, which is pressed downward or lifted upward, and avoid that the movement stroke is too large, so that a local pressure applied to the cloth is too large, which may affect the scribing precision, a spring for driving the telescopic rod 306 to return is arranged on the telescopic rod 306.

Example 3:
