Abstract

The invention provides a connector device of a cord fabric cutting machine and a method thereof, which feed the previous cord fabric and the next cord fabric in sequence forwards by adopting the same integrated connector conveying belt, and lift the tail part of the previous cord fabric from the conveying belt before the connector is stitched and position the cord fabric so as to completely solvethe problem of dynamic shortage of a strip of the cord fabric and realize a resistance-free conveying mode. The connector device of the cord fabric cutting machine is mainly provided with a frame carrying the connector conveying belt, wherein the connector conveying belt is driven by a servo motor and conveys the cord fabric along the vertical direction of the frame; the front end of the frame isprovided with a connector mechanism which is used for connecting the previous cord fabric and the next cord fabric together; the upper part of the frame is only provided with the integrated connectorconveying belt; the vertical length of the conveying belt is larger than the maximum length specification of the conveyed cord fabric; the front end of the connector conveying belt is provided with acord fabric lead device; and a cross beam of the connector mechanism is provided with an adsorption mechanism which is used for upwards lifting and positioning the end part of the cord fabric.

Example Embodiment

[0058] Example 1, such as Figure 3 to Figure 7-4 As shown, the joint device of the cord cutting machine mainly includes a frame 1 carrying a joint conveyor belt 2, and only one integral joint conveyor belt 2 is provided on the upper part of the frame 1.

[0059] The joint conveyor belt 2 is driven by a servo motor 3 and conveys the curtain along the longitudinal direction of the frame 1, and its longitudinal length is 1.3 times the maximum length of the conveyed curtain.

[0060] The front end of the frame 1 is provided with a joint mechanism 4 for connecting the front and rear curtains together.

[0061] At the front end of the joint conveyor belt 2 is provided a curtain pull-out device 5, the curtain pull-out device 5 includes a vertically fixed pull-out roller 51 and a unidirectional pressure roller 52 arranged above the pull-out roller 51.

[0062] The vertical height of the leading roller 51 is higher than the joint conveyor belt 2.

[0063] On the beam of the joint mechanism 4, a suction mechanism for lifting and positioning the end of the curtain is provided.

[0064] When the joint is pressed with a steel cord, the adsorption mechanism used is a magnet sucker 61, which uses the magnet sucker to attract the tail of the previous cord and lift it off the joint conveyor 2.

[0065] When the fiber cord is pressed into the joint, the suction mechanism used is the vacuum suction cup 62, and the tail of the previous cord is sucked and lifted off the joint conveyor belt 2 by the magnet suction cup.

[0066] On the upper part of the frame 1 and the rear side of the joint mechanism 4, a set of photoelectric sensors 7 are provided.

[0067] The joint method of the curtain cutting machine is to drive the joint conveyor belt 2 through the servo motor 3 and convey the curtain along the longitudinal direction of the frame 1, and use the joint mechanism 4 to perform joint pressing at the junction of the front and rear curtains.

[0068] The two curtain fabrics with the head and the tail jointed and pressed together are sequentially conveyed forward to the joint mechanism 4 by the same integral joint conveyor belt 2.

[0069] Before the joint is pressed, the previous curtain is drawn out from the front end of the joint conveyor belt 2 through the curtain pulling device 5, and the tail of the previous curtain is lifted upwards from the joint conveyor belt 2 by an adsorption mechanism and positioned.

[0070] When the head of the next curtain reaches the joint mechanism 4, the tail of the previous curtain is released by the suction mechanism and falls down and engages with the head of the next curtain.

[0071] Before the joint pressing is performed, the previous curtain cloth passes between the lead-out roller 51 and the one-way pressing roller 52 and is drawn out from the front end of the joint conveyor belt 2.

[0072] Before the joint is pressed, the tail of the previous curtain is lifted up from the joint conveyor belt 2 by the magnet suction cup 61 or the vacuum suction cup 62 provided on the beam of the joint mechanism 4 and positioned.

[0073] During the conveying process of the front and rear curtains, the photoelectric sensor 7 arranged on the rear side of the joint mechanism 4 stops the tail of the previous curtain and the head of the following curtain at the joint mechanism 4.

[0074] Such as Figure 7-1 to Figure 7-4 As shown, the operation flow for realizing joint compression is:

[0075] The first step is to use the joint conveyor belt 2 to transport the first cord forward at a low speed, manually pass its head through the lead roller 51 and the one-way pressure roller 52, and use the photoelectric sensor 7 to control its tail to stop at the joint mechanism At 4 locations, the joint conveyor belt 2 stops running at this time;

[0076] In the second step, if the joint pressing is a steel cord, the tail of the first cord is sucked by the magnet sucker 61.

[0077] If the fiber cord is pressed by the joint, the tail is sucked by the vacuum suction cup 62,

[0078] The crossbeam of the joint mechanism 4 is driven to move upward by the air cylinder, and the tail of the first curtain is lifted up from the joint conveyor belt 2 and then positioned;

[0079] The third step is to use the same integrated joint conveyor belt 2 to transport the second curtain forward, and control the head of the second curtain to stop at the joint mechanism 4 through the photoelectric sensor 7. At this time, the joint conveyor belt 2 stops running ,

[0080] The air cylinder drives the beam of the joint mechanism 4 to reset downward, and the tail of the first curtain is released by the magnet suction cup 61 or the vacuum suction cup 62 and falls on the joint conveyor belt 2 again. At this time, the heads and tails of the front and rear curtains are connected to each other. , Use the joint mechanism 4 to joint and press;

[0081] In the fourth step, the joint conveyor belt 2 and the leading roller 51 start running at the same time. When the tail of the cord after the joint is separated from the photoelectric sensor 7, the fixed length mode is operated to ensure that the tail of the cord stops at the joint mechanism 4;

[0082] The fifth step is to repeat the operations from the second to the fourth step to sequentially and automatically perform the joint pressing between the multiple cords.

[0083] As described above, the present embodiment with reference to the drawings only describes the preferred embodiment of the present invention. Those skilled in the art can obtain enlightenment based on this, and directly derive other alternative structures that conform to the design concept of the present invention, and other structural features obtained therefrom should also belong to the scope of the solution described in the present invention.
