Technical Field

[0001] The present invention relates to the technical field of cloth spreading machines, and in particular to a structure and method for automatically recording cloth spreading machine data. Background Art

[0002] The operation records of existing spreading machines only record the cumulative number of spreading layers and other various operating data, while the actual number of layers of each cloth laid, the length of each cloth cut off, the length of the remaining cloth tail, the length of the secondary cloth cut off in the middle, the length of the remnant (overlapping) cloth and other data are all measured and recorded manually, and the difference between the incoming materials and the actual materials used is calculated, and then manually entered into the computer.

[0003] With the development of science and technology and the need for intelligent manufacturing and real-time collection of big data, manual recording and data entry methods can no longer meet the needs of current production. In addition, due to the uncertainty of workers' work ability, experience, and efficiency, the real-time and accuracy of the data cannot be guaranteed. Summary of the invention

[0004] The purpose of the present invention is to provide a structure and method for automatically recording data of a spreading machine, synchronously and automatically recording data when the spreading machine is working, reducing manual intervention and human errors, and ensuring the real-time and accuracy of the data.

[0005] In order to achieve the above object, the solution of the present invention is:

[0006] A structure capable of automatically recording data of a cloth spreading machine comprises an automatic cloth spreading machine, a cloth meter counter, a cloth spreading machine displacement device, a cloth sensor, a cutter sensor and a data processing module; the automatic cloth spreading machine comprises a transmission shaft for feeding cloth and a cutter for cutting cloth; the cloth meter counter is arranged opposite to the transmission shaft, and is used to measure the length data of cloth output by the automatic cloth spreading machine; the cloth spreading machine displacement device is installed on the automatic cloth spreading machine, and is used to measure the length data of the movement of the automatic cloth spreading machine; the cloth sensor is arranged opposite to the transmission shaft, and is used to detect whether there is any cloth; the cutter sensor is arranged opposite to the cutter, and is used to detect whether the cutter is working; the data processing module is used to receive data from the cloth meter counter and the cloth spreading machine displacement device, and judge, calculate and record data according to the status of the cloth sensor and the cutter sensor.

[0007] The cloth meter counter is a pulse encoder or a photoelectric displacement sensor.

[0008] The displacement device of the spreading machine is a pulse encoder or a photoelectric displacement sensor.

[0009] The data processing module is the control panel of the automatic spreading machine, which includes operation and setting functions in addition to data judgment, calculation and recording functions.

[0010] The data processing module is a terminal independent of the automatic cloth spreading machine, and the cloth meter counter, cloth spreading machine displacement device, cloth sensor, and cutter sensor are all detachably mounted on the automatic cloth spreading machine.

[0011] The structure capable of automatically recording the data of the cloth spreading machine also includes an alarm module electrically connected to the data processing module, and an alarm reminder is issued after the data processing module processes the data and triggers the corresponding alarm rules.

[0012] The alarm module includes a warning light and a horn installed on the automatic paving machine.

[0013] A method for automatically recording data of a cloth spreading machine, using the structure for automatically recording data of a cloth spreading machine, comprises the following steps:

[0014] Step 1, setting a preset board length and a preset number of layers on the automatic spreading machine;

[0015] Step 2: The automatic cloth spreading machine starts to work, the cloth spreading machine displacement device and the cloth meter meter start to measure the length data synchronously, and the data processing module records the data:

[0016] The cloth sensor senses the presence of cloth, the cloth meter starts measuring the length, the cloth spreading machine displacement device stops moving, the cutter sensor senses the cutting of the cutter at the same time, and the cloth meter starts measuring the length of the cloth head;

[0017] The fabric sensor senses the presence of fabric, and the fabric meter starts measuring the length. When the distance of the displacement device of the spreading machine retreats equals to the preset length, the cutter sensor senses the cutting of the cutter, and the distance of the displacement device of the spreading machine retreats is the spreading length, and the real-time number of layers is increased by 1.

[0018] The fabric sensor senses the presence of fabric, and the fabric meter starts to measure the length. When the backward length of the fabric spreading machine displacement device is less than the preset length, the cutter sensor senses that the cutter has cut, and the fabric meter measures the length again. The fabric spreading machine displacement device retreats again at the same time, and the cutter sensor senses that the cutter has cut again. The length measured again by the fabric meter is the length of the secondary fabric.

[0019] The cloth sensor senses the presence of cloth, the cloth meter stops measuring the length, and the length recorded when the cloth spreading machine displacement device moves forward longer than the previous cloth length and starts to move backward is the cloth spreading length;

[0020] The fabric sensor senses that there is no fabric, and the fabric meter stops measuring the length. When the length measured by the fabric meter is less than the preset length, and the shifter of the spreading machine moves forward again by a preset length after retreating by a length equal to the preset length, or when the current fabric pulling ends, the length measured by the fabric meter is the tail length of the fabric;

[0021] Step 3: When the real-time number of layers is equal to the preset number of layers, the automatic spreading machine stops working.

[0022] In step 2, when the upper and lower fabrics are mixed and spread:

[0023] For the upper cloth, the cloth sensor senses that there is no cloth, the cloth meter stop measuring the length, the cloth meter measuring length is less than the plate length, the cloth spreading machine displacement device retreats to a length equal to the preset plate length and then advances again, when its forward length is greater than the difference between the preset plate length and the measured length of the cloth meter, and is less than the preset plate length, the automatic cloth spreading machine retreats again and records data: the real-time number of layers of the next cloth + 1; the retreat length of the cloth spreading machine displacement device is added to the length of the upper cloth, and the length of the cloth tail is 0; the sum of the retreat length of the cloth spreading machine displacement device of the upper cloth and the retreat length of the cloth spreading machine displacement device of the lower cloth minus the preset plate length is recorded as the dislodged length of the lower cloth; the retreat length of the cloth spreading machine displacement device of the lower cloth minus the dislodged length of the lower cloth is added to the length of the lower cloth.

[0024] In step 2, the allowable error range for determining whether the retreat length measured by the displacement device of the spreading machine is equal to the preset length is within ±5%.

[0025] After adopting the above technical scheme, the present invention adds a fabric meter, a fabric spreading machine displacement device, a fabric sensor, a cutter sensor and a data processing module on the basis of the existing automatic fabric spreading machine. Automatic data collection can be performed while the automatic fabric spreading machine is working, reducing manual intervention, avoiding human errors, and ensuring that the collected data is real-time and accurate.

[0037] The above-mentioned cloth meter meter 2 is a pulse encoder or a photoelectric displacement sensor; the above-mentioned cloth spreading machine displacement device 3 is a pulse encoder or a photoelectric displacement sensor. The pulse encoder is an optical position detection element, and its encoding disk is directly mounted on the transmission shaft 11 to measure the rotation angle position and speed change of the shaft. Its output signal is an electric pulse, which can directly output data to the data processing module 6; the photoelectric displacement sensor uses photoelectric detection to achieve the measurement of displacement. In addition, the cloth sensor 4 and the cutter sensor 5 can use infrared sensors.

[0038] The data processing module 6 is the control panel of the automatic cloth spreading machine 1, which includes operation and setting functions in addition to data judgment, calculation and recording functions.

[0039] Alternatively, the data processing module 6 can also be a terminal independent of the automatic cloth spreading machine 1, and the cloth meter 2, the cloth spreading machine displacement device 3, the cloth sensor 4, and the cutter sensor 5 are all detachably mounted on the automatic cloth spreading machine 1. These components can be integrated into a movable device and used between different cloth spreading machines.

[0040] The present invention further comprises an alarm module electrically connected to the data processing module 6, which makes an alarm after the data processing module 6 processes the data and triggers the corresponding alarm rule. In this embodiment, the alarm module comprises a warning light 71 and a speaker 72 installed on the automatic paving machine 1.

[0041] The present invention also includes a method for automatically recording data of a cloth spreading machine, using the above-mentioned structure for automatically recording data of a cloth spreading machine, comprising the following steps:

[0043] Step 2, the automatic cloth spreading machine 1 starts working, the cloth spreading machine displacement device 3 and the cloth meter meter 2 start to measure the length data synchronously, and the data processing module 6 records the data:

[0044] (Cloth spreading starts) The cloth sensor 4 senses that there is cloth, and the cloth meter 2 starts to measure the length (when the cloth meter 2 reverses, the recorded length needs to be deducted), the cloth spreading machine displacement device 3 stops moving, and the cutter sensor 5 simultaneously senses that the cutter 12 is cutting, and the length that the cloth meter 2 starts to measure is the length of the cloth head;

[0045] (Cloth spreading starts) Fabric sensor 4 senses that there is fabric, fabric meter 2 starts to measure the length (when fabric meter 2 reverses, the recorded length needs to be deducted), when the backward length of spreading machine displacement device 3 (when the forward distance of spreading machine displacement device 3 is less than the plate length, the backward length needs to be deducted) is equal to the preset plate length, cutting knife sensor 5 senses that cutting knife 12 cuts, and the backward length of spreading machine displacement device 3 is the spreading length, and the real-time number of layers is increased by 1;

[0046] (Cloth spreading process) When the fabric sensor 4 senses that there is fabric, the fabric meter 2 starts to measure the length (when the fabric meter 2 reverses, the recorded length needs to be deducted), and the spreading machine displacement device 3 retreats the length (when the spreading machine displacement device 3 retreats the length less than the plate length, the retreat length needs to be deducted) less than the preset plate length, the cutter sensor 5 senses that the cutter 12 cuts, and the fabric meter 2 measures the length again, and the spreading machine displacement device 3 retreats at the same time again, and the cutter sensor 5 senses that the cutter 12 cuts again, and the length measured by the fabric meter 2 again is the secondary cloth length;

[0047] (Cloth spreading process) The fabric sensor 4 senses the presence of fabric, the fabric meter 2 stops measuring the length, and the length recorded when the fabric spreading machine displacement device 3 moves forward longer than the previous fabric length (the same fabric) and then starts to move backward is the fabric spreading length;

[0048] (Cloth spreading process) The fabric sensor 4 senses that there is no fabric, and the fabric meter 2 stops measuring the length. The length measured by the fabric meter 2 is less than the preset length. The fabric spreading machine shifter 3 moves back to a length equal to the preset length and then moves forward again (to load the upper and lower fabrics) for a preset length or when the current cloth stretching is finished, the length measured by the fabric meter 2 is the length of the tail of the fabric.

[0049] Step 3: When the real-time number of layers is equal to the preset number of layers, the automatic spreading machine 1 stops working.

[0050] In step 2 above, when the upper and lower fabrics are mixed and laid:

[0051] Upper cloth, (cloth spreading process) cloth sensor 4 senses that there is no cloth, cloth meter 2 stops measuring length, the measured length of cloth meter 2 is less than the plate length, and the cloth spreading machine displacement device 3 retreats to a length equal to the preset plate length and then advances again (installs upper and lower cloths), when its forward length is greater than the difference between the preset plate length and the measured length of cloth meter 2 and is less than the preset plate length, the automatic cloth spreading machine 1 retreats again and records data: the real-time number of layers of the next cloth + 1; the retreat length of the cloth spreading machine displacement device 3 is added to the length of the upper cloth, and the length of the cloth tail is 0; the sum of the retreat length of the cloth spreading machine displacement device 3 of the upper cloth and the retreat length of the cloth spreading machine displacement device 3 of the lower cloth minus the preset plate length is recorded as the dislodged length of the lower cloth; the retreat length of the cloth spreading machine displacement device 3 of the lower cloth minus the dislodged length of the lower cloth is added to the length of the lower cloth.

[0052] In the above step 2, the allowable error range for determining whether the retreat length measured by the cloth spreading machine displacement device 3 is equal to the preset plate length is within ±5%.

[0053] Through the above scheme, the present invention adds a cloth meter 2, a cloth spreading machine displacement device 3, a cloth sensor 4, a cutter sensor 5 and a data processing module 6 on the basis of the existing automatic cloth spreading machine 1. Automatic data collection can be performed while the automatic cloth spreading machine 1 is working, reducing manual intervention, avoiding human errors, and ensuring that the collected data is real-time and accurate.

[0054] The above embodiments and drawings do not limit the product form and style of the present invention. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present invention.
