Problems solved by technology

But in actual work, when there is a fault in each roll of fabric or the cloth is spread, a breakpoint will occur, and the spreader will automatically return to the original point, and then the operator will manually move to the fabric breakpoint after finishing the fabric. The position is adjusted left and right before spreading. The existing problems are: due to manual operation, the spreading device is moved to the breakpoint position, which increases labor intensity, reduces production efficiency and is low in automation.

Embodiment 1

[0033] like figure 1As shown, the breakpoint memory automatic return system used on the cloth spreading machine is applied to the cloth spreading machine. The cloth spreading machine includes a frame 1, a cloth bed 2, a cloth spreading device 6 and a control cabinet 3. The control cabinet 3 is installed in the The controller on the frame 1 and in the control cabinet 3 is a processing module based on PLC, and a touch screen 4 and a reset switch 5 are installed on the frame 1, and the touch screen 4 is used for input and output. The touch screen 4 is provided with a breakpoint button 41, and the reset switch 5 is a proximity switch and is in contact with and away from the spreading device 6. The cloth spreading device 6 can move back and forth at both ends of the cloth bed 2; certainly the cloth spreading device 6 can also include a cloth feeding structure and a cloth clamping structure, the cloth clamping structure is fixed on the other end of the cloth bed 2, and the cloth fee...

Embodiment 2

[0046] The spreading machine includes a frame 1, a cloth bed 2, a spreading device 6 and a control cabinet 3. The control cabinet 3 is installed on the frame 1 and the controller in the control cabinet 3 is a processing module based on PLC. A touch screen 4 and a reset switch 5 are installed, and the touch screen 4 is used for input and output. The reset switch 5 is a proximity switch and is in contact with and away from the spreading device 6 .

[0047] like figure 2 As shown, the automatic return control method includes the following steps:

[0048] S1. A coordinate establishment module is provided, which is used to establish a coordinate system (X, 0) for various positions of the cloth bed 2 along the cloth spreading direction;

[0049] S2, a breakpoint detector 7 is provided, installed at the outlet of the cloth spreading device 6, along with the cloth spreading device 6 can move back and forth on the cloth bed 2, for detecting whether there is cloth 8 coming out of the...

Embodiment 3

[0060] The difference between this embodiment and Embodiment 2 is that the specific method for determining the breakpoint coordinate module is: an encoder is installed on the motor shaft of the spreading device 6, and the stroke of the moving of the spreading device 6 after the encoder rotates one circle is S1, the rotation angle of the encoder is Q, since the spreading device 6 touches the reset switch 5 after a back and forth, the timing of the controller will also be cleared, so there are only two situations in the operation, one is the breakpoint pulse signal appears In the process that the spreading device 6 is gradually moving away from the initial position, the distance between the breakpoint and the initial position is S=S1*Q / 360; the other is that the breakpoint pulse signal appears when the spreading device 6 is gradually approaching the initial position. , the distance from the breakpoint to the initial position at this time is S=2*D-S1*Q / 360; where D is the distance...

Abstract

The invention provides an automatic break point memory returning system for a cloth spreader and a control method, belongs to the cloth spreader control technology field and solves problems of low efficiency and low automation degree caused by manual movement to the break point position after a cloth spreader has a cloth break point in the prior art. The automatic returning system comprises a break point detector, a break point button and a controller used for establishing a coordinate system (X, 0) along the position of a cloth bed in the cloth spreading direction, receiving a break point pulse signal, analyzing and calculating a break point coordinate value (X1, 0) corresponding to the position of the cloth spreader on the cloth bed when the break point pulse signal is generated, receiving a reset signal and further controlling the cloth spreader for moving to the corresponding position on the cloth bed corresponding to the break point coordinate value (X1, 0) for cloth spreading. The automatic break point memory returning system is advantaged in that the break point can be automatically identified, the cloth spreader can be automatically reset to the break point, the automationdegree is high, and efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of spreader control, and relates to a breakpoint memory automatic return system and a control method for a spreader. Background technique [0002] Spreading machine is through the active rotation of the cloth, so that the roll material is in a natural state without external force, layer by layer on the table to become a multi-layer flat state, suitable for applications of various lengths. [0003] For example, the disclosed publication number is CN105442295B, a Chinese patent titled a multi-layer spreading machine and a multi-layer spreading system. The cloth feeding device includes N cloth feeding cradles, N is a natural number greater than or equal to 2, cloth feeding cradles are provided with cloth rolls, and the cloth feeding cradles can drive the cloth rolls to rotate and send out the cloth; The cloth pulling head on the bed and the cloth holding head arranged on the cloth bed; wherein, the cloth pulli...
