Description

Technical Field

[0001] This application belongs to the technical field of glass fiber production equipment, specifically relating to a clip-type automatic feeding mechanism for an automatic sleeve of a fiber drawing machine. Background Technology

[0002] A brief introduction to the manufacturing process of glass fiber: After formulating the raw ore, it is melted into molten glass in a furnace, flows out through a porous platinum stencil, is coated with a sizing agent by a monofilament oiler, and is then drawn into ultrafine fibers by various high-speed rotating drawing equipment such as drawing machines. These fibers are either wound into direct untwisted rovings or into raw filament cakes. Several drawing and winding methods require the use of a winding bobbin to form the roving, which can be made of paper or Teflon. Currently, the drawing process has been automated with features such as automatic head loading, no-cut yarn ring loading, cutting of intermediate connecting yarns, and unloading robots, replacing manual labor. However, after the robot removes the roving, a manual person must still put the winding bobbin onto the drawing machine head for further drawing and winding. This is not only inefficient but also poses safety hazards due to human-machine collaboration, hindering the overall automated production process.

[0003] Please refer to the Chinese patent: An automatic loading and unloading mechanism for fiberglass drawing machines [Application Publication No.: CN115783899 A / Application No.: 202211622113.6]. Existing automatic sleeve-sleeving equipment for fiber drawing machines generally cannot carry the winding spool, requiring multiple reciprocating movements between the winding spool storage rack and the drawing machine during sleeve loading, thus affecting the spool loading efficiency. Utility Model Content

[0004] In view of this, this application provides a clip-type automatic feeding mechanism for an automatic sleeve of a wire drawing machine, in order to solve all or part of the technical problems described in the background section of this application.

[0005] The innovative concepts of this application are: 1. Folding the wire winding cylinder into a square thin sheet to facilitate material stacking and carrying; 2.

[0006] The solution provided in this application to resolve its technical problem is as follows:

[0007] A clip-type automatic feeding mechanism for automatic sleeves in wire drawing machines includes a lifting feeding group, a primary sleeve feeding mechanism, and a secondary sleeve feeding mechanism;

[0008] The lifting and feeding group is used to complete the pressure-holding lifting and progressive feeding of the folding wire winding cylinder. The first-stage feeding mechanism is used to transfer the folding wire winding cylinder from the lifting and feeding group to the second-stage feeding mechanism. The second-stage feeding mechanism is used to open the opening of the folding wire winding cylinder and feed it forward.

[0009] Preferably, the lifting and feeding assembly includes a lifting drive component and a lifting platform; the lifting drive component is driveably connected to the lifting platform. More preferably, the lifting drive component is a rodless lifting cylinder; the lifting platform is mounted on the lifting slide of the rodless lifting cylinder. More preferably, the lifting and feeding assembly also includes a pressure-holding valve.

[0010] Preferably, the lifting and feeding assembly also includes a lifting guide column and a limiting component; the lifting guide column is used to guide the lifting movement of the lifting platform, and the limiting component is used to limit the movement range of the lifting platform.

[0011] Description of the lifting and feeding unit: Multiple wire-winding spools are folded into square sheets and stacked on the lifting platform. The lifting and feeding unit uses rodless cylinders to complete the step-by-step feeding of the folded wire-winding spools. Each time the primary feeding mechanism moves a wire-winding spool horizontally, the lifting drive component drives the lifting platform to deliver a folded wire-winding spool upwards. Thus, the robot arm can carry multiple wire-winding spools and perform automated feeding, avoiding the back-and-forth movement between the wire drawing machine and the storage rack when the robot arm picks up spools.

[0012] Preferably, the primary feeding mechanism includes a winding bobbin push-pull plate and a push-pull drive component; the push-pull drive component is connected to the winding bobbin push-pull plate.

[0013] Preferably, the bobbin push-pull plate includes a horizontal portion and a vertical portion; the horizontal portion is used to receive driving force from the lifting drive component, and the vertical portion is used to push and pull the bobbin from its edge. More preferably, the push-pull drive component is a push-pull cylinder; the piston rod of the push-pull cylinder is connected to the horizontal portion of the bobbin push-pull plate.

[0014] Preferably, the primary feeding mechanism also includes a push-pull plate guide rod; the push-pull plate guide rod is used to guide the push-pull action of the winding drum push-pull plate to increase stability.

[0015] Description of the primary feeding mechanism: The wire winding bobbin push-pull plate can move the folded wire winding bobbin horizontally from the upper feeding position of the lifting feeding group to the upper feeding position of the secondary feeding mechanism, that is, between the upper opening bobbin assembly and the lower opening bobbin assembly, under the action of the push-pull drive component.

[0016] Preferably, the secondary tube feeding mechanism includes a tube feeding frame, a tube feeding drive component, an upper tube opening assembly, and a lower tube opening assembly; the upper and lower tube opening assemblies are respectively located at the upper and lower parts of the tube feeding frame and are oriented opposite to each other, and the tube feeding drive component is driven to the tube feeding frame.

[0018] Preferably, the secondary feeding mechanism also includes a feeding frame guide rod; the feeding frame guide rod is used to guide the translational movement of the feeding frame to increase stability.

[0019] Description of the secondary feeding mechanism: The upper and lower opening components respectively suck up the folding winding spool from the upper and lower sides. Then, the opening cylinder drives the opening suction cup to open the opening of the folding winding spool. Next, the feeding drive component drives the feeding frame to feed the winding spool forward and place it on the support device.

[0020] As a preferred embodiment, the automatic feeding mechanism for the automatic sleeve of the wire drawing machine also includes a chassis; the lifting feeding group, the primary feeding mechanism, and the secondary feeding mechanism are all mounted on the chassis.

[0021] Preferably, the automatic feeding mechanism of the clip type for the automatic sleeve of the wire drawing machine also includes a traveling mechanism; the traveling mechanism is used to drive the chassis to move.

[0022] To automate the feeding of the wire winding drum, the clip-type automatic feeding mechanism needs to be able to perform reciprocating motion in the XYZ axes. An existing AGV platform or an XYZ three-axis drive system can be used as the walking mechanism in this application. The entire machine's movement can be achieved by mounting the robot chassis onto the AGV platform or XYZ three-axis drive system. The walking mechanism is existing technology and will not be described in detail here.

[0023] Beneficial technical effects:

[0024] 1. This application uses a lifting platform to store folded wire winding spools and a rodless pressure-holding cylinder to achieve the spring-loaded feeding of folded wire winding spools in stages; the robotic arm can carry multiple wire winding spools and perform automated feeding, thereby avoiding the reciprocating movement between the wire drawing machine and the storage rack when the robotic arm picks up the spools, which is conducive to improving equipment efficiency.

[0025] 2. The automatic feeding mechanism of the clip type disclosed in this application allows multiple processes to be carried out synchronously. The lifting platform can immediately deliver the next winding bobbin upward after the primary feeding mechanism completes the push-pull translation of one winding bobbin; the primary feeding mechanism can immediately push-pull translation of the next winding bobbin after feeding one winding bobbin to the upper and lower opening components of the secondary feeding mechanism; the secondary feeding mechanism can immediately pick up and open the next winding bobbin after placing one winding bobbin on the subsequent support device; thus, when the winding bobbin on the drawing machine head and the automatic feeding mechanism are being translated, the materials on the lifting platform, the primary feeding mechanism, and the secondary feeding mechanism are all ready; thus, by synchronizing or overlapping the processes, it is beneficial to improve the efficiency of automatic feeding.

[0038] Please see Figures 1 to 4 The automatic feeding mechanism for automatic sleeves of wire drawing machines disclosed in this application includes a lifting feeding group 110, a primary feeding mechanism 120, and a secondary feeding mechanism 130.

[0039] The lifting and feeding group 110 is used to complete the pressure-holding lifting and progressive feeding of the folding wire winding cylinder. The first-stage feeding mechanism 120 is used to transfer the folding wire winding cylinder from the lifting and feeding group 110 to the second-stage feeding mechanism 130. The second-stage feeding mechanism 130 is used to open the opening of the folding wire winding cylinder and convey it to the flipping feeding mechanism 20.

[0040] Among them: the lifting and feeding group 110 feeds the winding drum by means of cylinder pressure holding in a spring-clamp type pressure holding progressive feeding; for each time the first-stage drum feeding mechanism 120 moves away one folding winding drum, the lifting and feeding group 110 delivers the next folding winding drum upward.

[0041] The lifting and feeding assembly 110 includes a lifting drive component 1110, a lifting platform 1120, a lifting guide column 1130, and a limiting component 1140. The lifting drive component 1110 is driveably connected to the lifting platform 1120. The lifting drive component 1110 and the lifting guide column 1130 are mounted on the robot chassis 30 and extend vertically; the limiting component 1140 is located on the top of the lifting guide column 1130. The lifting drive component 1110 is a rodless lifting cylinder, and the lifting platform 1120 is mounted on the lifting slide of the rodless lifting cylinder. The lifting platform 1120 is provided with corresponding structures, such as guide sleeves, for cooperating with the lifting guide column 1130.

[0042] The folded wire bobbins, in the form of square sheets, are stacked on the lifting platform 1120. A rodless lifting cylinder uses a throttle valve or pressure-holding valve to achieve step-by-step pressure-holding feeding of the folded wire bobbins. The lifting guide column 1130 provides motion guidance for the lifting platform 1120 to improve feeding stability, and the limiting component 1140 limits the movement range of the lifting platform 1120. This allows the robotic arm to carry multiple wire bobbins and perform automated feeding, avoiding the reciprocating motion between the wire drawing machine and the wire bobbin storage rack when the robotic arm retrieves the bobbins.

[0043] The primary bobbin feeding mechanism 120 includes a bobbin push-pull plate 1210, a push-pull drive component 1220, and a push-pull plate guide rod 1230. The bobbin push-pull plate 1210 includes a horizontal portion 1211 and a vertical portion 1212. The horizontal portion 1211 receives the driving force from the push-pull drive component 1220, and the vertical portion 1212 pushes or pulls the bobbin from the edge of the folded bobbin. The push-pull drive component 1220 is a push-pull cylinder, which is driven to the horizontal portion 1211. The push-pull plate guide rod 1230 is horizontally arranged to provide motion guidance for the bobbin push-pull plate 1210 to increase the smoothness of the push-pull action.

[0044] When the piston rod of the push-pull cylinder extends, it pushes the winding drum push-pull plate 1210 to the rear end of the lifting and feeding position. When the piston rod of the push-pull cylinder retracts, it pulls the winding drum push-pull plate 1210 and the winding drum to the front end of the lifting and feeding position, that is, between the upper opening drum assembly 1330 and the lower opening drum assembly 1340 of the secondary drum feeding mechanism 130.

[0045] In a modified implementation, the push-pull cylinder can also be located on the rear side of the lifting and feeding position; when the piston rod of the push-pull cylinder extends, it pushes the folding winding bobbin between the upper opening assembly 1330 and the lower opening assembly 1340; when the piston rod of the push-pull cylinder retracts, it pulls the winding bobbin push-pull plate 1210 to the rear end of the lifting and feeding position.

[0046] The secondary tube feeding mechanism 130 includes a tube feeding frame 1310, a tube feeding drive component 1320, an upper tube opening assembly 1330, a lower tube opening assembly 1340, and a tube feeding frame guide rod 1350.

[0047] The tube feeding guide rod 1350 is horizontally mounted on the robot arm chassis 30 via a vertical column, and the tube feeding frame 1310 is slidably connected to the tube feeding guide rod 1350 via a guide sleeve. The tube feeding drive component 1320 is a tube feeding cylinder, which is mounted on the robot arm chassis 30 and driven to the tube feeding frame 1310. The upper tube opening assembly 1330 and the lower tube opening assembly 1340 are respectively located at the upper and lower parts of the tube feeding frame 1310 and are oriented opposite each other.

[0048] Both the upper opening assembly 1330 and the lower opening assembly 1340 include an opening cylinder 1331 and an opening suction cup 1332; the opening cylinder 1331 is driven to the opening suction cup 1332. The upper and lower opening suction cups 1332 face each other to simultaneously grip the folded winding bobbin from both the upper and lower sides; the upper and lower opening cylinders 1331 extend and retract in opposite directions so that the opening of the folded winding bobbin is opened by the simultaneous retraction of the two piston rods.

[0049] Description of the secondary feeding mechanism: The upper and lower opening components respectively suck up the folded winding bobbin from the upper and lower sides. Then, the opening cylinder drives the opening suction cup to open the opening of the folded winding bobbin. Next, the feeding drive component 1320 drives the feeding frame 1310 to feed the partially opened winding bobbin onto the subsequent support device.

[0050] The feeding process of the aforementioned automatic feeding mechanism for the automatic sleeve of the wire drawing machine is described below. For the sake of simplicity, the following is a simplified description: the lifting drive component 1110 of the lifting feeding group 110 is a rodless lifting cylinder, the push-pull drive component 1220 of the first-stage cylinder feeding mechanism 120 is a push-pull cylinder, the cylinder feeding drive component of the second-stage cylinder feeding mechanism 130 is a cylinder feeding cylinder, and the drive component of the upper and lower cylinder opening assembly is an opening cylinder.

[0051] S01, Under the pressure-holding state of the rodless lifting cylinder, the lifting and feeding group 110 starts to work;

[0052] S02, the push-pull cylinder of the first-stage feeding mechanism 120 starts to work, moving the folded winding bobbin forward between the upper and lower opening components;

[0053] S03, the upper opening assembly 1330 and the lower opening assembly 1340 of the secondary tube feeding mechanism 130 are working, and the vacuum generator is started;

[0054] S04, the upper and lower cylinders operate simultaneously to open the opening of the winding spool;

[0055] S05, the secondary feeding cylinder of the secondary feeding mechanism 130 feeds the material forward and places the wire winding cylinder on the subsequent support cylinder equipment;

[0056] S06, the upper and lower cylinders blow away in opposite directions, causing the upper and lower cylinder suction cups to separate from the winding drum;

[0057] S07, the cylinder of the secondary cylinder feeding mechanism 130 drives the secondary cylinder feeding mechanism 130 to return to its original position;

[0058] S08. Repeat the above steps to complete the continuous automated feeding of the wire winding drum.

[0059] In summary, the clip-type automatic feeding mechanism for automatic sleeves in wire drawing machines disclosed in this application can not only carry multiple winding spools, but also achieve automated feeding of winding spools through the cooperation of a lifting feeding group, a primary spool feeding mechanism, and a secondary spool feeding mechanism. This avoids the reciprocating motion between the wire drawing machine and the storage rack when the robotic arm retrieves spools, thus improving equipment efficiency. Furthermore, since multiple spool feeding processes can be performed synchronously or alternately, it also helps to improve the efficiency of automatic spool feeding.

[0060] The technical solutions and effects of this application have been described in detail above with reference to the accompanying drawings and specific embodiments. It should be noted that those skilled in the art can develop other embodiments based on this. Any simple modifications and equivalent substitutions that do not depart from the innovative concept of this application are covered by this application and fall within the protection scope of this patent.
