Description

Technical Field

[0001] The invention belongs to the field of finishing and detecting flexible wool-like materials, and in particular relates to a method for finishing and height detecting flexible wool-like materials. Background Art

[0002] At present, flexible hair-like materials are widely used in the eyelash beauty industry. Since flexible hair-like materials are required to align the hair tips and not cross each other when used most of the time, most of the manufacturing industry currently adopts manual sorting. After sorting, they enter the manual retrieval stage. This manual sorting and retrieval process takes a long time and is costly, and there are large differences in manual work and judgment between people. Automatic hair retrieval requires the height of the flexible hair-like material to be determined first. Flexible hair-like materials are relatively fluffy. If the height of the flexible hair-like material is taken as the actual height of the flexible hair-like material, the amount of flexible hair-like material obtained during automatic hair retrieval will be insufficient, resulting in major defects in the products of subsequent processes. Summary of the invention

[0003] In order to solve the problems of manpower waste and uneven standards in the existing production process of flexible wool-like materials, the present invention provides a method for the arrangement and height detection of flexible wool-like materials. The specific technical solution is as follows:

[0004] A method for arranging and height detecting a flexible wool-like material comprises an oscillation arranging step and a height detecting step. In the oscillation arranging step, the flexible wool-like material is arranged into a non-crossed state by oscillation, and the wool tips are aligned; in the height detecting step, the actual height of the flexible wool-like material after compaction is obtained by compaction as a taking height.

[0005] Furthermore, the shock sorting step includes the following sub-steps:

[0006] Step 1.1, the rubbing stick first moves to the middle point B, then from the middle point B to the left point A, and then from the left point A to the right point C, and in this way, the rubbing stick moves back and forth between the left point A and the right point C. After each oscillation, the count value H increases by 1;

[0007] Step 1.2, calculate the pulse attenuation X of the first servo motor, pulse attenuation X=pulse decrement D*count value H;

[0008] Step 1.3, calculate the coordinate pulses of the left point A and the right point C after the pulse attenuation, the coordinate pulse of the left point A = the coordinate starting pulse of the left point A + the pulse attenuation amount X, the coordinate pulse of the right point C = the coordinate starting pulse of the right point C - the pulse attenuation amount X;

[0009] Step 1.4: When the count value H is equal to the oscillation target setting value Y, stop the oscillation, rub the rod back to the middle point B, and reset the counter.

[0010] Furthermore, the vibration sorting step is implemented by a material box vibration mechanism, in which the flexible wool-like material to be sorted is placed, and the rubbing rod is arranged in the material box 1 and is covered by the flexible wool-like material. The rubbing rod is driven to reciprocate left and right by the rubbing rod motion mechanism, and the rubbing rod motion mechanism is driven by the first servo motor through a transmission belt.

[0011] Furthermore, the pulse decrement amount D and the oscillation target setting value Y are set in advance and can be adjusted to obtain different finishing effects.

[0012] Furthermore, the height detection step includes the following sub-steps:

[0013] Step 2.1, the lifting Y axis quickly drops to the detection starting position, at which time the cylinder axis is not under pressure and maintains the initial state;

[0014] Step 2.2: The lifting Y axis slowly descends to the initial position of the cylinder until the magnetic opening signal is lost. At this time, the card plate contacts the flexible wool material;

[0015] Step 2.3: After the magnetic opening signal is lost, the lifting Y axis continues to descend slowly for 1 second;

[0016] Step 2.4, the lifting Y axis slowly rises to the cylinder initial position magnetic open signal, and the lifting Y axis coordinate zero_0 is recorded. At this time, the flexible wool material is in a completely compacted state, and this height is the detection height of the flexible wool material;

[0017] Step 2.5, set the target access times of the coordinate zero_0, and when the actual access times equals the target access times, re-perform height detection.

[0018] Furthermore, the height detection step is implemented by a compaction detection mechanism, which includes a card plate, which is used to extrude the flexible wool-like material after finishing. The card plate is arranged on the cylinder shaft of the cylinder. A magnetic switch is arranged in the cylinder. The cylinder is driven up and down by the second servo motor through the lifting screw transmission module for the lifting Y-axis.

[0019] Furthermore, the height detection step adjusts the cylinder pressure by using a pressure reducing valve to obtain different compaction tightness.

[0020] The flexible wool material arrangement and height detection method of the present invention adopts high-speed attenuation oscillation to arrange the flexible wool material into a non-crossed state faster than traditional manual methods, and does not require manual operation, which is conducive to the automatic movement of the machine for taking the flexible wool material; the cylinder is used to achieve accurate measurement of the zero point position of the flexible material; the elastic mechanism realized by the gas pressure of the cylinder achieves stable and adjustable pressure, and is durable compared to general elastic mechanisms; the magnetic opening signal is used as the position recording signal for accurate measurement and easy maintenance.

[0030] The flexible wool-like material finishing and height detection method of the present invention comprises an oscillation finishing step and a height detection step. In the oscillation finishing step, the flexible wool-like material is arranged into a non-crossed state by oscillation, and the wool tips are aligned; in the height detection step, the height of the flexible wool-like material after compaction is obtained by compaction, so as to prepare for subsequent wool removal.

[0031] like Figure 1 and 3 The oscillation sorting step is implemented by a material box oscillation mechanism, a flexible wool-like material to be sorted is placed in the material box 1, a rubbing rod 2 is arranged in the material box 1 and is covered by the flexible wool-like material, the rubbing rod 2 is driven by a rubbing rod motion mechanism 3 to reciprocate left and right, and the rubbing rod motion mechanism 3 is driven by a first servo motor 4 through a transmission belt 5.

[0032] The shock finishing step includes the following sub-steps:

[0033] Step 1.1, the rubbing stick first moves to the middle point B, then from the middle point B to the left point A, and then from the left point A to the right point C, and in this way, the rubbing stick moves back and forth between the left point A and the right point C. After each oscillation, the count value H increases by 1;

[0034] Step 1.2, calculate the pulse attenuation X of the first servo motor, pulse attenuation X=pulse decrement D*count value H; pulse decrement D is set in advance; the number of pulses of the first servo motor is gradually reduced, so that the frequency of the reciprocating motion of the rubbing rod is gradually increased, and the amplitude of the reciprocating motion of the rubbing rod is gradually reduced; by using the high-speed attenuation oscillation of the rubbing rod, the oscillation amplitude decreases as the number of oscillations increases, and the oscillation frequency increases as the number of oscillations increases. Under high-speed oscillation, the flexible wool material is arranged into a non-crossed state for use;

[0035] Step 1.3, calculate the coordinate pulses of the left point A and the right point C after the pulse decays, the coordinate pulse of the left point A = the coordinate starting pulse of the left point A + the pulse decay amount X, the coordinate pulse of the right point C = the coordinate starting pulse of the right point C - the pulse decay amount X. In this way, the left point A and the right point C of the rubbing rod movement limit gradually move closer to the middle point B;

[0036] Step 1.4: When the count value H is equal to the oscillation target setting value Y, stop the oscillation, rub the rod back to the middle point B, and reset the counter.

[0037] The vibration finishing step effectively increases the vibration frequency of the rubbing rod. In the final stage of rubbing, the amplitude of the rubbing rod is reduced, thereby reducing the problem of cross-over of flexible wool materials caused by large amplitude and improving the stability of vibration grooming.

[0038] The pulse decrement amount D and the oscillation target setting value Y can be adjusted to achieve the best finishing effect.

[0039] like Figure 2 and 4 As shown, the height of the flexible wool material after the shaking and arranging step needs to be determined before taking it out. If the flexible wool material is in a fluffy state, the amount of wool taken out by the wool taking mechanism will be less than the actual amount required. Therefore, it is necessary to compact the wool material to obtain the height of the compacted flexible wool material, so as to prepare for the subsequent wool taking.

[0040] The height detection step is implemented by a compaction detection mechanism, which includes a card plate 6, which is used to extrude the flexible wool-like material after finishing. The card plate 6 is arranged on the cylinder shaft of the cylinder 7. A magnetic switch is arranged in the cylinder 7. The cylinder 7 is driven up and down by the second servo motor 8 through the lifting screw transmission module 9 for the lifting Y-axis.

[0041] The height detection step includes the following sub-steps:

[0042] Step 2.1, the lifting Y axis quickly drops to the detection starting position, at which time the cylinder axis is not under pressure and maintains the initial state;

[0043] Step 2.2: The lifting Y axis slowly descends to the initial position of the cylinder until the magnetic opening signal is lost. At this time, the card plate contacts the flexible wool material;

[0044] Step 2.3: After the magnetic opening signal is lost, the lifting Y axis continues to descend slowly for 1 second;

[0045] Step 2.4, the lifting Y axis slowly rises to the cylinder initial position magnetic open signal, and the lifting Y axis coordinate zero_0 is recorded. At this time, the flexible wool material is in a completely compacted state, and this height is the detection height of the flexible wool material;

[0046] Step 2.5, set the target access times of the coordinate zero_0, and when the actual access times equals the target access times, re-perform height detection.

[0047] The height detection step can be performed by using a pressure reducing valve to adjust the cylinder pressure, so that the cylinder maintains elasticity to obtain different compaction tightness, press the flexible wool-like material, detect its actual stacking height, and use the cylinder stroke and magnetic opening signal to perform fixed-point stroke recording to record the actual available material removal height of the flexible wool-like material.
