Description
Technical Field
The utility model relates to an equipment of unreeling of one-way strip, concretely relates to possess strip equipment of unreeling of rectifying system in coordination.
Background
In order to quickly disperse ballistic shock stress waves, most of high-performance bulletproof composite materials are in a structure form of non-woven cloth and are formed by cross compounding two or more layers of unidirectional cloth.
By unidirectional fabric is meant a textile fabric having in one direction (usually the warp direction, but also the weft direction unidirectional fabric) a large number of woven or untwisted rovings, and in the other direction no or only a small number of and usually fine yarns, the full strength of the fabric being in one direction.
The ultra-high molecular weight polyethylene material applied to the bulletproof field mainly has two forms, one is in a fiber form, and the other is in a strip form. The production process of the fiber unidirectional fabric mainly comprises the processes of filament spreading, surface treatment, gum dipping, drying and the like. The ultra-high molecular weight polyethylene tapes have two-dimensional physical forms, are limited in the current production process level, are difficult to directly obtain wide (such as more than 1000mm width) tapes suitable for bulletproof products, and need to produce unidirectional tapes by splicing narrow tapes.
For the narrow band spliced wide unidirectional cloth, the traditional unreeling device is generally in a through shaft mode, and a slip shaft can be selected for increasing tension control. The slip shaft has the advantages and disadvantages that the slip shaft is obvious, for example, the advantages of simple device, small occupied space and capability of providing tension control to a certain degree; however, the method has certain disadvantages, such as independent tension of each coil cannot be independently controlled, feeding and discharging must be carried out in a whole batch, convenient material changing is not facilitated, all strip coils are placed on a through shaft, when a certain coil positioned in the middle is exhausted or quality problems occur, all coils must be unloaded, the material changing of the middle coil can be completed, and time and labor are wasted.
Furthermore, it is difficult to adjust the position of the strip when the strip position is laterally shifted during the transfer. When the strips are shifted in the transverse direction, gaps between adjacent strips are too large, or the strips overlap, and both gaps between strips and overlaps adversely affect the unidirectional fabric. The processing method for the strip deviation mainly depends on correcting the transverse position of the coiled material on the unreeling device, however, the existing unreeling device mainly depends on manually finding and adjusting the position of the coiled material, so that effective deviation correction is difficult to achieve, and time and labor are wasted. More importantly, the unidirectional cloth is usually composed of a plurality of strips, when gaps or overlapping occur in the middle of the unidirectional cloth in the strip transportation process, the defects in the middle of the unidirectional cloth cannot be eliminated only by adjusting the position of a single coiled material, so that the manual deviation correction is not only time-consuming and labor-consuming, but also the deviation correction effect is not good, and therefore the conventional unreeling device needs to be improved.

Example 1
The embodiment relates to an unwinding device for unidirectional cloth strips. As shown in fig. 1 to 3, fig. 1 is a schematic view of an overall structure of a unidirectional fabric tape unwinding apparatus described in the present embodiment, fig. 2 is a side view, fig. 3 is a front view thereof, and fig. 4 is a schematic view of arrangement of main components with a part of a secondary structure omitted.
The unidirectional cloth strip unwinding device shown in the embodiment comprises a rack 10, wherein 11 coiled material unwinding devices 20 are arranged on the rack 10, and each coiled material unwinding device 20 is correspondingly provided with a transverse displacement mechanism 30. Be provided with a plurality of support horizontal poles 11 in the frame 10, divide into 3 layers with frame 10, coiled material unwinding mechanism 20 in frame 10 places in the second floor according to (i) coiled material unwinding mechanism, No. two coiled material unwinding mechanism places in the first floor, No. three coiled material unwinding mechanism sets up in the third floor, No. four coiled material unwinding mechanism places in the order on second floor, analogize with this, set up whole coiled material unwinding mechanism intervals on the three-layer bracing piece, arrange like this and can avoid taking place the position conflict between the axle 21 of unreeling of adjacent coiled material unwinding device 20 and transverse displacement mechanism 30, thereby make the strip 40 that coiled material unwinding device 20 release obtained closely arrange to unidirectional cloth 50. The gap between any two adjacent strips is correspondingly provided with a gap monitoring device 60, and the transverse displacement mechanism 30 and the gap monitoring device 60 are both connected with a controller, which is not shown in the figure. The gap monitoring device 60 is a machine vision dimension detecting device, performs a dimension measurement on the corresponding strip gap 41 every 4 seconds, and sends the dimension measurement result to the controller. Wherein the time interval of the measurement is adaptively adjustable according to the speed of travel of the strip 40 and/or the position of the gap monitoring device 60; similarly, the adjustment frequency of the strip 40 can be simulated according to the end face neatness of the raw material coil or the gap variation range, so that the consistency of detection, prejudgment and execution can be continuously optimized, and the frequency can be automatically adjusted after the material travels for a certain distance and for a certain time.
The unwinding shaft 21 of the coiled material unwinding device 20 is an inflatable shaft, and when the coiled material 22 is not placed on the coiled material unwinding device 20, the unwinding shaft 21 is in a loose state, so that the coiled material 22 can be conveniently loaded and unloaded; after the feeding of the coiled materials is completed, the unwinding shaft 21 is ventilated, the air expansion shaft expands and tensions, the coiled materials 22 are fixed on the unwinding shaft 21, the phenomenon that the tension of the strips 40 is uneven due to the fact that the coiled materials 22 slip is avoided, and therefore the effect of avoiding the position deviation of the strips 40 is achieved.
The transverse displacement mechanism 30 comprises a sliding plate 31, the coiled material unwinding device 20 is arranged on the sliding plate 31, a sliding rail 32 and a deviation rectifying motor 33 are arranged below the sliding plate, the sliding rail 32 is arranged along the width direction of the strip 40, and the controller can control the deviation rectifying motor 33 to drive the sliding plate 31 to move on the sliding rail 32. When the lateral displacement mechanism 30 receives an instruction from the controller, the deviation correcting motor 33 starts to operate, so as to drive the coiled material unwinding device 20 arranged on the sliding plate 31 to move along the sliding rail 32.
The unwinding device for the unidirectional cloth strips further comprises a tension control module 70, wherein the tension control module 70 comprises a tension detection roller 71, two driving rollers 72 and a tension brake 73, the tension detection roller 71 and the tension brake 73 are connected with a controller, and the tension brake 73 controls the resistance of the coiled material unwinding device 20 to release the strips 40. The angles formed by each tension detection roller 71 and two adjacent driving rollers 72 are the same, and the tension detection rollers 71 and the two adjacent driving rollers 72 are arranged between the coiled material unwinding device 20 and the gap monitoring device 60, so that the tension on the strip 40 can be adjusted before the strip is corrected, and if the tension is adjusted after the strip is corrected, the strip 40 after the correction may deviate again due to the change of the tension. When the tension control module 70 works, the tension roller 71 feeds back the monitored tension value to the controller, and the controller judges whether the tension applied to the strip meets the requirement. When the controller determines that the tension applied to the strap 40 is too high, it sends a command to the tension brake 73 to reduce the release resistance of the web 22; the controller determines that the tension on the strip 40 is too low and sends a command to the tension brake 73 to increase the release resistance of the web 22. The tension of each strip 40 adjusted by the tension control module 70 is stable during the transmission process, and the function of avoiding the transverse deviation of the strip 40 caused by the tension change during the conveying process can be achieved.
The working process of the unidirectional cloth strip unwinding equipment is as follows:
first, the plurality of coils 22 are placed on the unwinding shaft 21, and the air-inflation switch is opened to fix the coils 22 to the unwinding shaft 21. And then the strips 40 released from the coiled material 22 sequentially penetrate through the driving rollers and the tension detection roller 71 according to the mode shown in fig. 2, finally all the penetrating paths of the strips 40 are converged on the same driving roller to form the unidirectional fabric 50, and the strips 40 forming the unidirectional fabric 50 continue to penetrate through the subsequent processing equipment along the subsequent driving roller until the blanking equipment. The whole production line is started, and the driving roller in the subsequent equipment drives the strip 40 to advance along the preset direction, so as to drive the coiled material unreeling equipment 20 to release the coiled material 22, and obtain the strip 40 which advances towards the subsequent equipment.
After the web unwinding apparatus 20 starts unwinding, the strip 40 is released from the web 22 and passes through the tension detecting roller 71 and the gap monitoring device 60 in sequence along the predetermined direction.
During the forward movement of the strip 40, the tension detection roller 71 continuously detects the tension applied to the strip 40, feeds the detected tension value back to the controller, and sends a command to the tension brake 73 to reduce the release resistance of the web 22 when the controller judges that the tension is excessive; when the controller determines that the tension is too low, it sends a command to the tension brake 73 to increase the release resistance of the web 22, thereby controlling the tension experienced by the strip 40 to stabilize.
The deviation rectifying process of the unwinding device for unidirectional cloth strips according to this embodiment is as follows (the "left" and "right" are described based on the relative position of fig. 3 in the following description):
in this embodiment there are 11 coils 22, and therefore 11 strips 40, and 10 strip gaps 41. The 11 strips 40 are collected on the same transmission roller to form the unidirectional fabric 50, when the unreeling device runs stably and the position of each strip 40 in the unidirectional fabric 50 is adjusted properly, each gap monitoring device 60 measures the width X of the corresponding strip gap 41 every 4 seconds, and feeds back the measurement result to the controller. In this embodiment, the width X of the tape gap 41 is required to be in the range of 0.5mm to 5mm, and the width X is preferably 2 mm. Since the tape 40 is usually pulled by a worker manually to penetrate the transmission roller, the unidirectional fabric 50 which is just penetrated is usually wrinkled, overlapped and the like, and the unidirectional fabric 50 can be regular and stable only after the equipment runs for a period of time, so that the gap monitoring device 60 is required to start to collect data after the equipment runs stably.
The unidirectional cloth after the equipment stably operates is shown in fig. 3, wherein 11 strips 40 in the figure are sequentially marked as N from left to right 0 ，N 1 ，……，N 10 (ii) a The 10 gap monitoring devices 60 in the figure are labeled M in sequence from left to right 1 ，M 1 ，……，M 10 (ii) a The widths of the 10 gaps 41 corresponding thereto, which are monitored by the 10 gap monitoring devices 60, are sequentially marked as X 1 ，X 2 ，……，X 10 . Whenever M is present i Measuring the corresponding strip gap 41 to obtain the measured value X i Then, the measured value X is measured i Sending to the controller, judging X by the controller i Whether the numerical value of (A) is within the required range of 0.5mm-5mm, when the controller judges that X is within the required range of 0.5mm-5mm i When the thickness is larger than 5mm, the controller moves to N i The corresponding lateral displacement mechanism sends a leftward movement (X) i -2) an instruction of mm; when the controller judges X i When the thickness is less than 0.5mm, the controller moves to N i The corresponding lateral displacement mechanism sends a right movement (2-X) i ) mm instructions.
Specific examples are as follows, for example, when the strip N 5 And a band N 6 When the gap between the two parts is widened, the response flow of the whole deviation correcting system is as follows:
1) due to the strip N 5 And a band N 6 Clearance monitoring device M 6 Measuring the corresponding strip gap every 4s, and measuring the measured gap width X 6 Sent to the controller, thus when the gap monitoring device M is in use 6 Monitoring the corresponding strip gap width X 6 If it is larger than 5mm, for example, 5.5mm, the controller judges X 6 Greater than 5mm, towards N 6 The corresponding lateral displacement mechanism 30 is commanded to move 5.5-2-3.5 mm to the left, at which time t is assumed to be 0 ；
2)N 6 The corresponding transverse displacement mechanism 30 drives the corresponding coiled material to unreelThe strip at device 20 has moved 3.5mm to the left;
3)(t 0 +4s), strip N 6 The corresponding strip 40 moving leftwards at the coil unreeling device 20 moves to the gap monitoring device M 6 At this time M 6 Again proceeding with gap width X 6 And sending the measurement result to the controller, and the controller again compares X with the other 6 And judging whether the requirements are met. At this time X 6 Has been corrected to the range of 0.5mm-5mm, at the same time, due to the band N 6 Moved to the left, strip N 6 And N 7 In-between, i.e. clearance monitoring means M 7 Corresponding gap width X 7 Usually, it will change accordingly, so that when the gap width X is changed 6 While corrected, the controller also simultaneously aligns the gap width X 7 Is judged if X is 6 The correcting action of (2) makes X 7 If the value of (2) does not meet the standard, the controller also moves to N 7 The corresponding transverse displacement mechanism 30 sends a moving instruction to move the corresponding roll unwinding device 20.
3)(t 0 +8s), strip N 7 The corresponding strip 40 moved by the coil unreeling device 20 moves to the gap monitoring device M 7 A, M 7 Again for its corresponding strip gap X 7 Measure and send the measurement result to the controller, and the controller again compares X 7 Judging whether the requirements are met;
4) likewise, X 7 If X is satisfied after the width of (A) is satisfied 7 Is simultaneously adjusted for X 8 Has an effect on the width of X, the controller controls X 8 The width of (a) is adjusted, and so on until all the strip gaps 41 meet the requirements.
In the above rectification example process, the visual representation of the motion of the equipment is as follows:
a) during the transmission of the unidirectional fabric 50 obtained by splicing the strips 40 on the transmission roller, 10 gap monitoring devices 60 on the equipment continuously perform the monitoring on the width X of each gap on the unidirectional fabric 50 every 4s 1 -X 10 Carrying out measurement;
b) number N 5 And N 6 Of the stripWidth X of gap therebetween 6 When it becomes wider, the controller finds its change and moves it to N 6 The corresponding lateral displacement mechanism 30 sends a command to move 3.5mm to the left, and the time at this point is assumed to be t 0 ；
c) Subsequent strip N 6 The corresponding lateral displacement mechanism 30 is moved 3.5mm to the left, (t) 0 +4s) rear gap monitoring device M6 the strip N6 moved 3.5mm to the left, X 6 Meets the requirement and simultaneously causes the gap width X 7 Broadening, controller finding X 7 Widening towards N 7 The corresponding lateral displacement mechanism 30 sends a command to move to the left, causing the strip N to move 7 Moving to the left;
d) by analogy, stripe N 8 To N 10 Also successively move to the left, finally at (t) 0 +20s) to achieve elimination of the excessively large gap occurring in the middle of the unidirectional fabric 50.
The above description is about the elimination process of the too large gaps with gaps larger than 5mm in the unidirectional cloth 50, and when the too small gaps smaller than 0.5mm are present in the unidirectional cloth, the system response and the device motion performance are similar, and for brevity, the details are not repeated here.
