Description

Technical Field

[0001] The present invention belongs to the field of textile machinery, and particularly relates to a device for manufacturing a continuous spiral net. Background Art

[0002] The spiral net is a common filtering material, usually made of high molecular plastics such as PP and polyester fibers, and has advantages such as high temperature resistance and acid and alkali resistance, and is widely used in the processing of various filtering materials. Chinese Patent CN02203004.2 discloses a spiral net structure. Usually, in the processing process of the spiral net, it is necessary to first form a spiral structure loop by a single filament through a looping machine, and then overlap the spiral structure loops on a net connecting machine. After that, the net connecting machine automatically introduces a single filament into the overlapping loops to form a spiral net sheet. Each spiral net sheet is composed of 30 left-handed spiral structure loops and 30 right-handed structure loops in parallel, with a length of about 20 cm. For the specific structure, see Figure 1 However, when the spiral net is used as a filtering material, a large area is required, and the traditional equipment cannot produce a spiral net long enough at one time, and can only splice a longer spiral net through a splicing process. In the traditional splicing process, workers stand and operate facing the net connecting machine. The net connecting machine is responsible for producing spiral net sheets, and there is a net connecting platform downstream for connecting the sheets into a net. The net connecting platform has a certain width and height. Whether it is through manual or mechanical means for wire threading operation, the phenomenon of missed threading and wrong threading of the net loops cannot be excluded. And in actual production, except for visual inspection, there is no other effective detection means for the spiral net. If the above-mentioned missed threading and wrong threading are not processed in time, it will cause a decline in the quality grade of the finished spiral net. Summary of the Invention

[0003] In order to solve the above technical problems, the purpose of the present invention is to provide a spiral net connecting platform for spiral net sheets that can provide automatic net threading and automatic detection.

[0004] For this purpose, the present invention adopts the following technical solutions:

[0005] A fully automatic spiral net connecting platform, comprising:

[0006] A spreading platform, having a tabletop extending along the X-Y plane, for placing two spiral net sheets to be spliced;

[0007] A sheet pushing mechanism, for sequentially pushing the spiral net sheets produced by the spiral net connecting machine to a specified position, so that the rear edge net loops of the next spiral net sheet overlap with the front edge net loops of the current spiral net sheet to be spliced, and the overlapping net loops of the two spiral net sheets are located on an overlapping line extending in the Y direction;

[0008] A flattening mechanism, for flattening the overlapping net loops of the two spiral net sheets located on the overlapping line so that they are nested with each other;

[0009] An automatic wire guiding mechanism is arranged on the side of the spreading platform and is configured to be able to introduce a single wire into the nested wire loops of the spiral mesh sheet and automatically feed or retract the wire along the Y direction.

[0010] A detection mechanism is used to detect whether the overlapping wire loops are correctly threaded and feedback a detection signal.

[0011] A winding mechanism is located downstream of the detection mechanism and is configured to be able to wind the spliced spiral mesh.

[0012] A control system is signal-connected to the pusher mechanism, the flattening mechanism, the automatic wire guiding mechanism, the detection mechanism, and the winding mechanism. The control system is configured to be able to receive the detection signal and send instructions to the automatic wire guiding mechanism, the flattening mechanism, the clamping and conveying mechanism, and the winding mechanism.

[0013] In the above technical solution, preferably, the spiral mesh full-automatic networking platform further includes a clamping and conveying mechanism capable of fixing the current spiral mesh to be spliced on the spreading platform. The clamping and conveying mechanism includes a pair of rotating wheel belts arranged along the Y-axis direction. The clamping and conveying mechanism and the winding mechanism are configured to be able to intermittently wind the spiral mesh.

[0014] In the above technical solution, preferably, the flattening mechanism includes at least one flattening roller and a flattening roller driving device. The flattening roller can move or roll along the X direction or the Y direction. The flattening roller can apply a uniform pressure to the overlapping spiral wire loops. By moving or rolling the flattening roller, the two overlapping wire loops of the spiral mesh are flattened and nested with each other.

[0015] In the above technical solution, preferably, the automatic wire guiding mechanism includes a set of first wire guiding rollers, a driving device for controlling the forward or backward movement of the single wire, and a cutting device for cutting the single wire. The cutting device includes a positioning cutter and an induction detector. The positioning cutter and the induction detector are respectively located on both sides of the operation platform.

[0016] In the above technical solution, preferably, the detection mechanism includes a photoelectric inspection device. The photoelectric inspection device includes a light emitter and a light receiver respectively arranged at both ends of the spreading platform along the Y-axis direction. The spiral mesh is configured to pass between the light emitter and the light receiver. The light emitter is configured to be able to emit a beam of light parallel to the Y-axis direction from one end of the edge wire loop where the wire threading position is located to the other end. The light receiver is used to receive the light beam passing through the detection wire loop and detect its intensity. The light emitter and the light receiver are respectively selected as a laser emitter and a laser receiver.

[0017] In the above technical solution, preferably, the detection mechanism further includes an image analysis and detection device located on the front or back of the spiral net. The image analysis device includes an image acquisition device, which is used to acquire the image information of the front or back of the spiral net. The image acquisition device is signal-connected to the control system. The control system includes a calculation and analysis module and an alarm module. The calculation and analysis module is configured to be able to compare and analyze the currently acquired image information with the standard image information of the standard spiral net and output the analysis result.

[0018] In the above technical solution, preferably, the winding mechanism is configured to be able to perform intermittent winding or unwinding of the spiral net. The linear distance of each winding or unwinding is the length of one spiral net sheet in the X direction. The intermittent time is set according to the time from the completion of the winding of the previous spiral net to the completion of the wire threading of the current spiral net.

[0019] In the above technical solution, preferably, the control system further includes a storage module for storing the standard spiral net pictures.

[0020] In the above technical solution, preferably, the spreading platform is provided with spiral net sheet positioning lines and positioners for fixing the position of the spiral net sheet in the working area.

[0021] In the above technical solution, preferably, the pusher mechanism includes a pusher and a pusher driving device. The pusher can accurately deliver the spiral net to be spliced on the spreading platform to the wire threading position.

[0022] In the above technical solution, preferably, the image acquisition device is located directly below the wire threading position, and the part of the spreading platform above the image acquisition device is set to be transparent and detachable.

[0023] In the above technical solution, preferably, the winding mechanism includes a winding shaft and a stepping motor for controlling the intermittent winding of the winding shaft.

[0024] In the above technical solution, preferably, the spreading platform further includes a second wire guiding roller for cooperating with the clamping and conveying mechanism and the winding mechanism to complete the tensioning and winding of the spiral net.

[0025] The full-automatic networking platform of the present invention is arranged downstream of the spiral net networking machine. Multiple spiral net sheets produced by the spiral net networking machine are spread on the spreading platform. The pusher mechanism accurately delivers the spiral net sheets to be spliced below the flattening mechanism, so that the edge wire loops of the spiral net overlap with each other. The flattening mechanism flattens the overlapping edge wire loops by rolling and applying a downward force, so that the two overlapping rows of edge wire loops are nested with each other. The automatic wire guiding mechanism transports the wire forward. The image detection mechanism can monitor the wire threading situation in real time through the transparent spreading platform. If abnormal wire threading is found, the control system sends a command signal to the automatic wire guiding mechanism. The automatic wire guiding mechanism retreats the wire slightly and then feeds the wire again to ensure that the wire threading process is accurate. When the induction detector on the other side of the networking platform senses the contact of the wire, the cutting device of the automatic wire guiding mechanism cuts off the single wire. Thereafter, the clamping and conveying mechanism cooperates with the winding mechanism to wind the length of a spiral net sheet in the X direction, so that the wire threading position enters the optoelectronic detection area. The optoelectronic detection mechanism performs a secondary detection on the edge wire loops. If there is no abnormality, the next wire threading process is carried out. If an abnormality is detected during the detection, the optoelectronic detection mechanism codes and marks the misthreaded position, and the spiral net retreats to the original wire threading position. After the single wire is slowly drawn out through a wire retreating component, wire threading, winding and detection are carried out again.

[0026] The present invention has the following beneficial effects compared with the current technology: realizing the automated production of spiral nets, improving the production efficiency of spiral nets, reducing the labor cost. In addition, the automatic detection mechanism can further ensure the quality of the finished spiral nets. Brief Description of the Drawings

Detailed implementation mode

[0033] To describe in detail the technical content, structural features, achieved objectives and effects of the invention, the following will be described in detail in combination with embodiments and with reference to the accompanying drawings. Among them, the Figure 2 upper part in the drawing is the "front" described in this specification, and the lower part is the "rear" described in this specification. Figure 2 The left side in the drawing is the "left side" in this specification, and the right side is the "right side" described in the specification. The Figure 3 rewinding direction in the drawing is from left to right. The Figure 2 X direction in the drawing is the "front and back" direction described in this article, and the Y direction is the left and right direction described in this article, that is, the "row direction". The "upper" and "lower" orientations described in the specification correspond to the upper and lower orientations shown in the Figure 3 drawing, and the "upstream" and "downstream" described in the specification correspond to the upstream and downstream positions along the rewinding direction respectively.

[0034] The spiral mesh is as Figure 1 shown. It is sequentially spliced along the X direction by multiple spiral mesh sheets 21, 22. Each spiral mesh sheet contains multiple rows of nested mesh rings. It includes two rows of edge mesh rings 211, 221 located on both sides of the spiral mesh sheet, and multiple intermediate mesh rings 212, 222 located between the two edge mesh rings. Through the spiral mesh networking platform, the edge mesh rings 211 and 221 of the adjacent two spiral mesh sheets: the first spiral mesh sheet 21 and the second spiral mesh sheet 22 can be overlapped with each other. By passing the monofilament 23 through the overlapping area of the two edge mesh rings, the first spiral mesh sheet 21 and the second spiral mesh sheet 22 can be connected into a spiral mesh. After splicing multiple sheets together, a continuous and longer spiral mesh coil can be formed.

[0035] The present invention provides a fully automatic spiral mesh networking platform, which can realize the automatic networking and automatic detection of multiple spiral mesh sheets. As Figures 2 - 5 shown, it includes the following components.

[0036] The frame 15 is used to support the networking operation platform and connect the following components.

[0037] The spreading platform 1 has a tabletop extending along the X-Y plane. The first spiral mesh sheet 21 and the second spiral mesh sheet 22 to be spliced are laid flat on the spreading platform 1. Positioning lines and positioners are provided on the spreading platform 1, which can detect whether the spiral mesh sheet has reached the specified position.

[0038] The sheet pushing mechanism 2 is used to sequentially push the spiral mesh sheets to be spliced to the above-mentioned specified position, so that the rear edge mesh loops 211 of the first spiral mesh sheet 21 overlap with the front edge mesh loops 221 of the second spiral mesh sheet 22, and the overlapping part of the two sheets is located on an overlapping line extending along the Y-axis direction, so as to facilitate subsequent flattening and wire threading.

[0039] The flattening mechanism 3 is used to flatten the overlapping mesh loops of the two spiral mesh sheets to be spliced located on this overlapping line, so that the edge mesh loops 211 and 221 are nested with each other. The flattening mechanism 3 can be as Figure 5 shown, including a pair of flattening rollers 31 whose axis directions extend along the X direction and can move along the Y direction, or it can also be a flattening roller whose axis extends along the Y direction and moves along the X direction. During the movement or rolling of the flattening roller 31, the mesh loops in the overlapping area are flattened, so that the single wire 23 can smoothly pass through all the overlapping mesh loops, that is, Figure 5 the wire threading position 25 in, and in this example, a pair of flattening rollers whose axis directions extend along the X direction and can move along the Y direction are selected.

[0040] The automatic wire guiding mechanism 4 is arranged on one side of the spreading platform 1. The automatic wire guiding mechanism 4 includes a group of first wire guiding rollers 14 and a driving device for controlling the feeding or retraction of the single wire 23, and also includes a positioning cutter 12 for cutting off the single wire after wire threading and an induction detector 13. Since the wire 23 used for splicing the spiral mesh is a high molecular material with a certain hardness, the automatic wire guiding mechanism 4 only needs to align the single wire 23 with the overlapping mesh loops after flattening, and then automatically feed the wire to be able to thread the single wire 23 into the mesh loops. Once the image detection mechanism under the spreading platform finds abnormal wire threading, the automatic wire guiding mechanism can also retract the wire and then feed the wire again, and finally make the wire 23 pass through all the overlapping mesh loops. When the wire threading of a row of mesh loops is completed, after the induction detector 13 on the right side of the spreading platform 1 senses that the single wire 23 has reached the position, the positioning cutter 12 can automatically cut off the wire on the left side of the operation platform.

[0041] The detection mechanism 27, located downstream of the automatic wire guiding mechanism 4, is configured to be able to detect the loop shape of the spiral net and feedback a detection signal to the control system. The detection mechanism includes an image detection mechanism 272 and a photoelectric detection mechanism 271. The image detection mechanism 272 is located directly below the wire threading position and can monitor the wire threading process in real time through the transparent and detachable spreading platform. Once abnormal wire threading is found, the control system sends a command signal to the automatic wire guiding mechanism 4. After the automatic wire guiding mechanism 4 retracts the wire slightly and then feeds the wire again, it ensures that the wire threading process is accurate. After splicing is completed, the clamping and conveying mechanism 7 and the second wire guiding roller 8 cooperate with the winding mechanism 9 to wind up the spiral net. The photoelectric detection mechanism 271 performs a secondary detection on the edge loop where the wire threading position is located. If there is no abnormality, the next splicing process is automatically carried out. If an abnormality is detected during the detection, the inkjet printing device in the photoelectric detection mechanism 271 can code and mark the misthreaded loop. The clamping and conveying mechanism 7 cooperates with the winding mechanism 9 to retract the spiral net back to the original wire threading position. After a single wire is slowly drawn out through a wire retracting assembly 16, it is re-threaded, wound up, and detected. The wire retracting assembly 16 is located on the right side of the spreading platform, opposite to the automatic wire guiding mechanism. The wire retracting assembly 16 can be realized by a pair of pinch wheels, clamping rollers, or jaws, etc. In this example, the wire retracting assembly 16 is realized by a pair of clamping rollers.

[0042] The winding mechanism 9 provides a tension force along the X direction. While realizing the winding or retraction of the spiral net, it can make the loops in the spiral net open, facilitating photoelectric detection. The winding mechanism 9 is driven by a stepping motor, and the winding line distance is the length of a spiral net sheet in the X direction.

[0043] The clamping and conveying mechanism 7 can fix the current spiral net to be wire-threaded, that is, the second spiral net sheet 22, on the spreading platform 1. The clamping and conveying mechanism 7 includes a pair of rotatable belt wheels that are respectively arranged on the left and right sides of the spreading platform and can move. When the clamping and conveying mechanism 7 stops rotating, it can press the spiral net against the spreading platform to fix it; when the clamping and conveying mechanism 7 is running, the clamping and conveying mechanism 7 also cooperates with the winding mechanism 9 to convey the spiral net forward or backward through friction, realizing the intermittent winding or unwinding of the spiral net, winding a fixed length each time, and stopping winding during wire threading.

[0044] The control system can be realized through a PLC controller or a computer system, and includes input / output devices, a calculation and analysis module, a storage module, an alarm module, and several sensors. The control system is respectively connected to the pushing plate mechanism 2, the flattening mechanism 3, the automatic wire guiding mechanism 4, the clamping and conveying mechanism 7, the detection mechanism 27, and the winding mechanism 9 by signals.

[0045] Among them, preferably, the optoelectronic inspection device 271 includes a laser emitter 5 disposed on the left side of the spiral mesh and a laser receiver 6 located on the right side of the spiral mesh. The laser emitter 5 is configured to emit a laser beam along the Y direction from inside the mesh loop. The laser receiver 6 is located at the other end of the mesh loop, for receiving the beam passing through the mesh loop, detecting its intensity, and simultaneously feeding back its intensity signal to the control system. After the first spiral mesh sheet 21 and the second spiral mesh sheet 22 are joined at the wire threading position 25, since the winding mechanism 9 provides a tension to the spliced spiral mesh, the spliced mesh loops in the spiral mesh are stretched. If there is no missed wire threading, then the contour of the edge mesh loop where the wire threading position 25 is located is neat, and there is a relatively large space in the middle of the edge mesh loop ( Figure 1 and 5 the detection position 24 in

[0046] ) that can allow all the detection light to pass through; if some mesh loops are missed, then the missed mesh loops will have no tension, resulting in uneven arrangement of the mesh loops, further blocking the detection beam, thereby reducing the intensity of the beam reaching the laser receiver 6. The control system can judge whether there is a missed mesh loop at the current detection position based on the beam intensity information fed back by the laser receiver 6.

[0047] The image acquisition device 272 includes an array camera for acquiring image information on the back of the spiral mesh. The image acquisition device 272 is signal-connected to the control system. The control system performs real-time graphic comparison and analysis on the image information fed back by the image acquisition device 272 and the standard image information of the standard spiral mesh, and judges whether there is a missed or misthreaded mesh loop.The control system first controls the sheet pushing mechanism 2 to push the first spiral mesh sheet 21 to be spliced into the specified position. The clamping and conveying mechanism 7 clamps and fixes the current second spiral mesh sheet 22 on the spreading platform 1, and overlaps the front and rear edge wire loops of the two sheets. The flattening roller 31 of the flattening mechanism 3 rolls in the overlapping area, so that the rear edge wire loop 211 of the first spiral mesh sheet 21 and the front edge wire loop 221 of the second spiral mesh sheet 22 are nested with each other. The automatic wire guiding mechanism 4 introduces the single wire 23 along the row direction into the nested wire loops. The image detection mechanism 272 located below the wire threading position monitors the wire threading process in real time. If wire threading is abnormal, the control system sends a command signal to the automatic wire guiding mechanism 4. The automatic wire guiding mechanism 4 retreats the wire slightly and then feeds the wire again until the wire threading is completed. When the induction detector 13 senses the arrival of the single wire, the positioning cutter 12 cuts off the single wire 23. The clamping and conveying mechanism 7 cooperates with the winding mechanism 9 to wind up the spiral mesh. The winding wire distance is the length of a spiral mesh sheet in the X direction, so that the just-completed edge wire loops 211 and 221 just reach the position where the photoelectric detection mechanism 271 is located, and then the spiral mesh is subjected to photoelectric detection. If the control system does not receive a wire threading abnormal signal, the next wire threading process can be carried out; if the control system receives a wire threading abnormal signal, the clamping and conveying mechanism 7 cooperates with the winding mechanism 9 to retreat the just-wired wire loop to the original wire threading position. The wire retreating component extracts the single wire and then the automatic wire guiding mechanism 4 feeds the wire automatically. After that, winding and detection are carried out again. When the detection passes, the next wire threading is carried out.

[0048] In addition, a weight sensor and a warning light are arranged on the bobbin holder included in the automatic wire guiding mechanism 4, and are set to turn on the warning light when the weight of the bobbin is lower than a certain value, reminding the worker to replace the bobbin in time;

[0049] When the above-mentioned networking operation platform is working, it is arranged downstream of the spiral mesh networking machine. Multiple spiral mesh sheets produced by the spiral mesh networking machine are spread on the spreading platform 1 to realize the automatic networking of multiple spiral mesh sheets.

Any equivalent changes or modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
