[0027] Embodiment:

[0028] Referring to Figure 1 , the present embodiment provides a pulp bag iron wire positioning system, which comprises a detection platform 1, a moving mechanism 2, an iron wire detection mechanism 3 and a control center.

[0033] The control center is connected with the moving mechanism 2, the iron wire detection mechanism 3, the pulp bag detector and the iron wire detector respectively, and is used for realizing pulp bag iron wire positioning.

[0034] Specifically, the moving mechanism comprises a servo motor 4 and a servo driver, the servo motor 4 is arranged on the detection platform 1, and the servo driver is connected with the control center and the servo motor respectively, and is used for receiving a control instruction and driving the servo motor 4.

[0035] In a specific embodiment, the detection platform 1 comprises a platform body, a longitudinal moving track 5 and a transverse moving track 6, the longitudinal moving track 5 is arranged on the platform body, the transverse moving track 6 is movably arranged on the longitudinal moving track 5 and along the length direction of the longitudinal moving track 5, and the moving mechanism 2 is movably arranged on the transverse moving track 6 and along the length direction of the transverse moving track 6.

[0036] In a specific embodiment, the wire detection mechanism 3 is adjustably arranged on the moving mechanism 2 along the length direction of the transverse moving track 6.

[0037] It should be noted that in the present embodiment, the movable arrangement can be driven by a chain and sprocket or other forms, and the power source is provided by the servo motor 4.

[0038] In a specific embodiment, the pulp bag detector includes a photoelectric switch 7, which is arranged on the moving mechanism 2 and is located in the same vertical plane as the wire detection mechanism 3. The photoelectric switch 7 in the present embodiment detects the position of the pulp bag without contacting the pulp bag, thereby positioning the wire in the next step.

[0039] In a specific embodiment, the wire detector includes two proximity switches 8, all of which are located in the same vertical plane.

[0040] The working process of the pulp bag wire positioning is as follows: the photoelectric switch 7 detects the pulp bag, and then the wire detection device is extended, the servo motor 4 is driven to make the wire detection mechanism 3 move quickly on the pulp bag, when the proximity switch 8 senses the wire, the position value of the detected wire is recorded. Finally, the offset is calculated according to the position value of the wire on the pulp bag, thereby driving the servo motor 4 to move horizontally to the corresponding position.

[0041] Further, the control center includes a human-machine interface and a controller, the human-machine interface is connected to the controller, and the controller is connected to the moving mechanism 2, the wire detection mechanism 3, the pulp bag detector and the wire detector respectively. The controller in the present embodiment is a programmable controller.

[0042] It should be noted that the human-machine interface and the servo driver communicate with the programmable controller through Profinet. The programmable controller displays the state of each sensor (photoelectric switch 7 and proximity switch 8 in the present embodiment) and the running process on the human-machine interface; the operator can set the speed and start-stop operation on the human-machine interface. The programmable controller includes a servo motion control block, a pulp bag positioning calculation block, a wire detection displacement block, an automatic positioning function block and an automatic start-stop control function block. The automatic positioning function block counts the different positions of the sensed wire by detecting the proximity switch 8, and then counts the automatic moving position and the target position of the automatic positioning by the speed and position value of the servo motor.

[0043] In addition, the embodiment further comprises a slurry bag iron wire cutting device, which comprises the iron wire cutting mechanism 9 and the slurry bag iron wire positioning system as described above.

[0044] Preferably, the iron wire cutting mechanism 9 is located in the same vertical plane as the iron wire detection mechanism 3, and the distance between the iron wire cutting mechanism 9 and the iron wire detection mechanism 3 is fixed. The iron wire cutting mechanism 9 in the embodiment can refer to the background art.

[0045] Specifically, the slurry bag iron wire positioning and cutting method in the programmable controller in the embodiment comprises the following steps:

[0046] (1) The photoelectric switch is responsible for detecting whether the slurry bag is within the detection range and transmitting the information to the programmable controller, and the proximity switch is responsible for detecting the position value of the iron wire and transmitting the information to the programmable controller;

[0047] (2) The programmable controller records the two position values X1_pos and X2_pos sensed by the two proximity switches when the iron wire detection device moves. If the iron wire is tilted, the programmable controller can calculate the center point position X3_pos according to the position values of the two points. If the iron wire is not tilted, the position value of X3_pos is equal to the position value of X2_pos;

[0048] (3) The programmable controller accurately calculates the positioning iron wire center position X3_pos through the position value X1_pos and the position value X2_pos through the principle of similar triangles, and adds a fixed offset value d between the iron wire detection mechanism 3 and the iron wire cutting mechanism 9, so as to obtain the position value to be moved, and control the servo motor to drive the iron wire cutting mechanism 9 to move to the corresponding position.

[0049] The specific calculation formula is as follows:

[0050] X3_pos=(X1_pos-X2_pos) / 2;

[0051] A_pos=d+X3_pos;

[0052] Wherein, A_pos represents the moving position value of the iron wire cutting mechanism 9, and the programmable controller drives the iron wire cutting mechanism 9 to move to the corresponding position through the moving position value, so as to realize the iron wire cutting.

[0053] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
