[0033] like Figures 1-3 As shown in the figure, this application provides a yarn insertion robot, including a lifting and flipping device 1, a vibrating hopper 2, a yarn feeding and lifting device 3, a yarn adjusting device 4, a conveying device 5, a yarn picking device 6, a negative pressure yarn feeding device 8, and a yarn delivery device 11.
[0034] The lifting and turning device 1 is used to transfer the bobbin from the bobbin transport vehicle to a vibrating hopper at a predetermined height.
[0035] The vibrating hopper 2 is used to store yarn tubes from the lifting and turning device, and the vibration causes the yarn tubes to roll down in an orderly manner to the discharge port of the vibrating hopper.
[0036] The bobbin feeding and lifting device 3 is connected and fixed to the outlet of the hopper 2, and is used to vertically lift the bobbin to a certain height.
[0037] The bobbin adjustment device 4 is located behind the bobbin feeding and lifting device 3. It is used to distinguish the large and small ends of the bobbin and adjust the falling direction of the bobbin so that the large end of the bobbin falls onto the conveying device 5.
[0038] The take-up device 6 is used to separate the yarn end from the yarn body of the bobbin that has fallen onto the conveying device 5, and to wrap the yarn end around the small end of the bobbin.

[0041] The workflow of the above-mentioned yarn insertion robot is as follows:
[0042] The bobbin is loaded into the bobbin transport vehicle, and the bobbin transport vehicle and the lifting and turning device 1 are fixed. The lifting and turning device 1 transfers the bobbin from the bobbin transport vehicle to the vibrating hopper 2 at a predetermined height.
[0043] The vibrating hopper 2 receives and stores the bobbins from the lifting and turning device 1, and the vibration causes the bobbins to roll down in an orderly manner to the discharge port of the vibrating hopper.
[0044] The bobbin feeding and lifting device 3 vertically lifts the bobbin from the outlet of the hopper to the bobbin adjusting device 4;
[0045] The yarn adjustment device 4 adjusts the falling direction of the yarn tube so that the large end of the yarn tube falls onto the conveying device 5.
[0046] The take-up device 6 separates the yarn end from the yarn body of the bobbin that has fallen onto the conveying device 5, and winds the yarn end around the small end of the bobbin;
[0047] The negative pressure yarn feeding device 8 adsorbs the yarn end of the small end of the bobbin, and the bobbin is conveyed and transferred by the conveying device 5 according to the specified path.
[0048] The yarn feeding device 11 receives the yarn head transferred by the negative pressure yarn feeding device 8 and feeds the yarn head and the corresponding yarn tube to the winding machine's yarn magazine.
[0049] In one embodiment, the yarn insertion robot also includes a control device 7 electrically connected to each device, the control device 7 including a display 72 and an electromagnetic valve cabinet 71.
[0050] In one embodiment, the yarn insertion robot may further include a fan device 9 connected to the negative pressure yarn feeding device 8 and the yarn feeding device 11, respectively. The fan device 9 provides negative pressure to the negative pressure yarn feeding device 8 and the yarn feeding device 11, respectively.
[0051] In one embodiment, the yarn insertion robot may also include an electrical cabinet 12 that provides power to all of the above devices.
[0052] In one embodiment, the yarn insertion robot may further include a roller device 10 disposed at the bottom of the frame.
[0053] The aforementioned robot can replace employees in high-intensity work and perform rapid material feeding and replenishment, improving the efficiency of the winding machine in replenishing yarn bobbins to meet the production line's needs. The yarn insertion robot of this invention achieves safe yarn bobbin transfer through a lifting and flipping device; the vibrating hopper causes the yarn bobbins to roll down in an orderly manner through vibration, avoiding tangling of the yarn ends; the yarn feeding and lifting device ensures the yarn bobbins are lifted vertically; the yarn adjusting device causes the yarn bobbins to fall onto the conveying device with the larger end facing down; the yarn picking device separates the yarn ends from the yarn body of the fallen bobbins and winds the yarn ends around the smaller end of the bobbins; the negative pressure yarn feeding device adsorbs the yarn ends at the smaller end of the bobbins; and the yarn delivery device receives the yarn ends transferred by the negative pressure yarn feeding device and delivers the yarn ends and corresponding bobbins to the winding machine's yarn magazine. The entire robot's modules operate in parallel, greatly improving work efficiency and allowing one employee to oversee multiple machines and focus on resolving malfunctions within the winding machine itself.
[0054] like Figures 4-5 As shown, in one embodiment, the lifting and tilting device 1 includes a device support 101, a tilting mechanism 102, a fixing mechanism 103, and a lifting mechanism 104.
[0055] The device bracket 101 is fixed to the side wall of the feed side of the hopper. The device bracket 101 is set on the frame of the yarn insertion robot and located on both sides of the hopper 2. The flipping mechanism 102, the fixing mechanism 103 and the lifting mechanism 104 are all installed on the device bracket 10.
[0056] The flipping mechanism 102 is mounted on the device bracket 101 and is used to flip the yarn transport vehicle to a predetermined position with the hinge point between the hopper and the device bracket as the axis.
[0057] The fixing mechanism 103 is installed on the tilting mechanism and is used to fix the yarn feeding cart on the tilting mechanism. The fixing mechanism 103 cooperates with the fixed part of the yarn feeding cart to fix it, and the fixing mechanism 103 fixes the yarn feeding cart on the tilting mechanism 102.
[0058] The lifting mechanism 104 is used to control the turning mechanism to achieve the in-situ turning of the yarn conveying car.
[0059] The device support 101 includes two mounting side plates symmetrically arranged on the feed side and a crossbeam connecting the two mounting side plates.
[0060] The flipping mechanism 102 includes a sliding flipping track 111 symmetrically mounted on the mounting side plate, a first guide wheel unit 112 moving within the sliding flipping track 111, a vertical track 113, at least one set of second guide wheel units 114 moving within the vertical track 113, and a flipping plate 115.
[0061] In one embodiment, the first guide wheel unit 112 includes two first guide wheels 1121 and a first connecting rod 1122 connecting the two first guide wheels 1121. The two first guide wheels 1121 move in sliding and flipping tracks 111 respectively, which are symmetrically installed on the inner walls of the two side plates 101 of the device bracket 10.
[0062] The first link 1122 ensures that the movements of the two first guide wheels 1121 are synchronized.
[0063] The second guide wheel unit 114 includes two second guide wheels 1141 and a second connecting rod 1142 connecting the two second guide wheels 1141. The two second guide wheels 1141 move in vertical tracks 113 symmetrically installed on the inner walls of the two side plates 101 of the device bracket 10. The first connecting rod 1142 ensures that the movements of the two first guide wheels 1141 are synchronized.
[0064] The first link 1122 prevents the two first guide wheels 1121 in the first guide wheel unit 112 from moving asynchronously, thus preventing the tilting plate 115 from tilting to the side. The second link 1142 prevents the two second guide wheels 1141 in the second guide wheel unit 114 from moving asynchronously, thus preventing the tilting plate 115 from getting stuck during lifting. Furthermore, it prevents the tilting plate 115 from tilting excessively to the side and the yarn transport vehicle from becoming too heavy during the tilting process, thus preventing the first guide wheel unit 112 from falling off the sliding tilting track 111. This also prevents the tilting mechanism 11 from crashing to the ground along with the yarn transport vehicle, improving the safety of the yarn transport vehicle lifting and tilting device.
[0065] In one embodiment, the lifting mechanism 104 includes a pneumatic cylinder or a hydraulic cylinder. A pneumatic cylinder converts the pressure energy of compressed air into mechanical energy, driving the mechanism to achieve reciprocating linear motion, oscillation, or rotation. A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy, performing linear reciprocating motion (or oscillation). In this embodiment, a pneumatic or hydraulic cylinder drives the tilting mechanism 102 to move simultaneously within the sliding tilting track 111 and the vertical track 113 via the first guide wheel unit 112 and the second guide wheel unit 114. The lifting and tilting actions of the tilting plate 115 are synchronized, and the tilting plate 115 drives the yarn transport vehicle to tilt in place.
[0066] like Figure 6 As shown, in one embodiment, the vibrating hopper 2 includes a hopper body 21, a sliding plate 22, a vibrating base plate 23, a vibrating mechanism 24, a wire end negative pressure suction mechanism 25, a shearing mechanism 26, and a lifting mechanism 27.
[0067] The silo body 21 has a feeding port at the top and a discharge port at the funnel-shaped bottom.
[0068] A sliding plate 22 is installed inside the hopper body to allow the yarn tubes from the yarn transport trolley to slide down slowly. The angle between the inclined surface of the upper surface of the sliding plate 22 and the horizontal ground is an acute angle. To shorten the transport path of the yarn tubes, the sliding plate 22 is fixed to the plate on the discharge side of the hopper body 21.
[0069] A vibrating base plate 23 is positioned below the sliding plate and forms a discharge port with the bottom surface of the sliding plate. It is used to control the orderly sliding of the yarn tubes from the sliding plate down the upper inclined surface of the vibrating base plate through vibration. The vibrating base plate 23 is fixed to the plate on the feed side of the hopper body 21. The inclination direction of the vibrating base plate 23 is opposite to that of the sliding plate 22.
[0070] The vibration mechanism 24 is used to control the vibration of the vibrating base plate.
[0071] A thread end negative pressure suction mechanism 25 is disposed at the tail end of the vibrating base plate for suctioning the thread end of the passing yarn tube by means of negative pressure. In one embodiment, the thread end negative pressure suction mechanism 25 is disposed on at least one slit 251 on the vibrating base plate 23 and a suction unit 252 disposed below the slit 251. The suction unit 252 includes a negative pressure suction machine and a negative pressure suction box. The negative pressure suction box is disposed below the slit 251 for wrapping the slit 251 and forming a sealed space.
[0072] The negative pressure suction machine evacuates air from the negative pressure suction box, creating a negative pressure space within the sealed area, thereby sucking up the yarn ends as they pass through the slit 251.
[0073] The shearing mechanism 26 forms a drop slit with the vibrating base plate, which is used to cut the ends of the passing yarn tubes.
[0074] The lifting mechanism 27 is located between the yarn end suction mechanism and the shearing mechanism and below the material drop slit. It is used to control the frequency at which the yarn ends that are suctioned are transported to the shearing mechanism.
[0075] The material drop slit can temporarily accommodate the yarn tube. When the downstream equipment does not need the yarn tube, the lifting mechanism 27 does not perform lifting operations, and the yarn tube is stored in the material drop slit. When the downstream equipment needs the yarn tube, the lifting mechanism 27 performs lifting operations, and the yarn tube is raised and lowered from the material drop slit until it exceeds the height of the shearing mechanism 26, and then the yarn tube passes over the top of the shearing mechanism 26.
[0076] Since the yarn end is still being held by the yarn end negative pressure suction mechanism 25 when the yarn tube passes the cutting mechanism 26, the cutting mechanism 26 can cut the yarn end of the yarn tube and obtain a yarn tube without yarn end winding.
[0077] like Figure 7 As shown, in one embodiment, the bobbin feeding and lifting device 3 includes a fixed frame 31, a feeding bin 32, a lifting module 33, a bobbin limiting module 34, and a separation module.
[0078] The fixed frame 31 is a cuboid frame; specifically, the fixed frame 31 is a polyhedral skeleton with 8 vertices, 12 outer edges, and 6 faces.
[0079] The feeding hopper 32 is installed at the bottom of the fixed frame and is used to hold the bobbins conveyed from the hopper. The feeding hopper 32 is an open hopper body. If a bobbin falls during the lifting process, the fallen bobbin falls into the open feeding hopper 32, and the lifting module 33 can lift the bobbin in the feeding hopper 32 again.
[0080] The lifting module 33 is installed within a fixed frame and is used to vertically lift the yarn bobbins in the feeding hopper to a predetermined height. The lifting module includes a support member fixed to the fixed frame, a lifting belt surrounding the support member, a drive assembly for driving the lifting belt, and multiple sets of lifting and supporting assemblies disposed on the lifting belt. Driven by the lifting belt, the lifting and supporting assemblies circulate around the support member to form a conveying channel located on one side of the support member. This conveying channel is used to vertically convey the yarn bobbins upwards.
[0081] The yarn bobbin limiting module 34 is installed on the fixed frame 31 and located inside the feeding bin 32. Through the coordinated movement of the yarn bobbin limiting module 34 and the lifting and supporting assembly 33, the yarn bobbins that are randomly fed to the lifting and supporting assembly 33 in the feeding bin 32 are orderly adjusted. This orderly adjustment includes adjusting the position and quantity of the yarn bobbins on the lifting module 33.
[0082] The separation module is installed at the top of the lifting module to separate the yarn tube from the lifting module and pass the yarn tube to the finishing device.
[0083] In one embodiment, the yarn adjusting device 4 includes an identification mechanism and a yarn splitting mechanism.
[0084] An identification mechanism is used to identify the direction of the yarn tube. The identification mechanism can be a camera unit and a processor that receives signals from the camera unit. The processor can be electrically connected to the display 72, or it can be the same processor as the display 72.
[0085] A yarn splitting mechanism is used to release the yarn bobbin with its larger end facing downwards based on the yarn direction identification result from the identification mechanism. The splitting mechanism may include a first baffle and a corresponding first flipping component, a second baffle and a corresponding second flipping component, and the yarn bobbin can fall onto the first and second baffles with its two ends respectively located on the first and second baffles. The first and second flipping components are positioned on the side near the yarn adjusting device of the yarn feeding and lifting device. The first flipping component drives the opening and closing of the first baffle, and the second flipping component drives the opening and closing of the second baffle.
[0086] like Figure 8 As shown, in one embodiment, the thread-picking device 6 includes a bracket 61, a second mounting base 62, a picking knife structure 63, a second air-jet structure 64, and a pressing rotation structure 65.
[0087] The bracket 61 is connected to the machine body and is positioned near the track of the yarn feeding station of the yarn insertion robot. The bracket 61 includes an "L"-shaped column, the short arm of which is fixed near the track where the picking knife station is located, while the long arm is parallel to the track. A second mounting base 62 and a picking knife structure 63 are mounted on the long arm of the column.
[0088] The pick-and-place mechanism 63 is used to separate the yarn end from the yarn body of the bobbin and, under inertia, winds the separated yarn end around the small end of the bobbin. For example... Figure 9 As shown, the picker structure 63 includes a first mounting base 631 and at least one picker 632. The first mounting base 631 and the second mounting base 62 are arranged in the same direction and are movable relative to the second mounting base 62. In one embodiment, the first mounting base and the second mounting base are connected by a lowering cylinder, and the relative movement between the first mounting base and the second mounting base is achieved by controlling the lowering cylinder. The picker 632 is flexibly mounted on the first mounting base 631, and the picker separates the yarn end from the yarn body of the bobbin. In one embodiment, the picker can be mounted on the first mounting base 631 by an elastic element such as a torsion spring or a rubber component to achieve flexible mounting. The torsion spring or rubber component can buffer the force and prevent the picker from breaking other yarns on the surface of the bobbin. The picker structure 63 also includes a first air jet structure 633, which provides upward force to the yarn cut by the picker structure 63 so that the yarn wraps around the small end of the bobbin under inertia.
[0089] The number of pickers 632 can be set according to the length of the picker station and the diameter of the yarn tube, or it can be set to a fixed value. The number of pickers 632 can be 1 to 8. For example, Figure 9 The number of scimitars is set to 4.
[0090] The second mounting base 62 and the first mounting base 631 are arranged in the same direction, and the first mounting base can move relative to the second mounting base.
[0091] The second jet structure 64 corresponds to the position of the pick-up knife and is used to jet air diagonally downwards into the yarn tube.
[0092] A clamping rotation structure 65 is disposed on the second mounting base 62 for clamping the bobbin and rotating it along the yarn winding direction. The clamping rotation structure 65 includes a movable base 652, a rotation mechanism, and a clamping drive member 651.
[0093] The movable seat 652 is set at the yarn take-up station to convey the yarn tube horizontally, and the yarn tube is fitted onto the movable seat. The yarn take-up station is equipped with a travel track for the movable seat.
[0094] The rotating mechanism includes a rotating component and a rotating drive component. The rotating component is located above the movable base. The rotating drive component is connected to the rotating component and is located below the movable base 652, providing the driving force for the rotating component to rotate.
[0095] The clamping drive 651 is mounted on the second mounting base 62 and can be vertically opposite to the movable base 652. It is used to cooperate with the rotating part to clamp or loosen the yarn tube.
[0096] In one embodiment, the pick knife includes a pick knife body and a pick knife blade.
[0097] The take-up knife body makes flexible contact with the surface of the yarn tube under the action of external force, and is used to pick up the outer layer of yarn on the surface. The take-up knife body includes a blunt blade for picking up the yarn, a mounting part installed on the take-up device, and a blade body section connecting the blunt blade and the mounting part.
[0098] The pick-up blade is located in the blade body and is used to cut the picked-up yarn from the yarn body.
[0099] like Figure 10 As shown, in one embodiment, the negative pressure yarn feeding device 8 includes a first negative pressure suction unit 81, a negative pressure rotary suction unit 82, a third negative pressure suction unit 83, and a control unit. The control unit can be connected to... Figure 3 The display 72 is electrically connected, or it is the same processor as the display 72.
[0100] The first negative pressure suction unit 81 includes a first suction head 811, a yarn end transfer unit 812, and a first negative pressure pipeline 813. The first suction head 811 sucks up the yarn ends of the bobbin conveyed to the first designated position on the worktable one by one, and the sucked yarn ends enter the first negative pressure pipeline 813.
[0101] The negative pressure rotary suction unit 82 has a swing arm and a second negative pressure pipeline connected to the swing arm. When the swing arm moves to the vicinity of the first suction head, the yarn end transfer unit temporarily blocks the first suction head and moves the yarn end to the vicinity of the swing arm. The swing arm uses negative pressure to suck up the yarn ends one by one.
[0102] The third negative pressure suction unit 83 uses negative pressure to suction the ends of multiple yarn tubes fed by the rotating swing arm.
[0103] The control unit is used to control the negative pressure of the first negative pressure suction unit 81, the negative pressure rotary suction unit 82, and the third negative pressure suction unit 83.
[0104] like Figure 11 As shown, in one embodiment, the first suction head 811 includes a vertical guide rod 8111 and a telescopic tube 8112.
[0105] The vertical guide rod 8111 is located near the first designated position, and the movable seat 8113 is sleeved on the outer side wall.
[0106] The telescopic tube 8112 can move up and down, with one end connected to the first negative pressure pipe 813, and the other end reciprocating vertically along the vertical guide rod 8111 under the drive of the movable seat 8113. The telescopic tube 8112 can accommodate the end of the yarn tube at the first designated position. When the end of the yarn tube enters the telescopic tube, the end of the yarn tube is in a negative pressure environment, so the yarn end can smoothly enter the telescopic tube 8112 and the first negative pressure pipe 813.
[0107] The yarn end transfer unit 812 is disposed at the port of the first suction head 811. The yarn end transfer unit 812 is used to guide the yarn end into the first negative pressure pipe or to guide the yarn end into the negative pressure rotary suction part.
[0108] The yarn end transfer unit includes a yarn end deflector and a drive unit.
[0109] The thread end deflector rotates horizontally along the port of the first suction head to guide the thread end into the first suction head or to guide the yarn end into the swing arm.
[0110] The drive unit is used to drive the wire end deflector.
[0111] like Figure 12 As shown, in one embodiment, the yarn delivery device 11 includes a robotic arm 121, a telescopic sleeve 122, and an airbag clamping tube assembly 123.
[0112] One end of the robotic arm 121 is fixed to the body of the yarn insertion robot, and the other end moves horizontally according to the control signal.
[0113] The telescopic sleeve 122 is fixed to the other end of the robot arm and can move vertically according to the control signal.
[0114] The airbag clamping assembly 123 is used to clamp at least one yarn tube and deliver the yarn tube to the winding machine's yarn magazine. The airbag clamping assembly 123 includes a fan-shaped mounting plate and multiple yarn clamps disposed at the front end of the mounting plate. The number of yarn clamps can be set from 1 to 8. The more yarn clamps there are, the more the fan shape of the mounting plate deviates from a circular shape.
[0115] The mounting plate has a hollow sleeve at its center, which is connected to the hollow pipe of the telescopic sleeve 122 for negative pressure suction of the yarn end of the transferred bobbin. This connection between the hollow sleeve and the hollow pipe of the telescopic sleeve 122 utilizes the hollow space of the lead screw to create negative pressure, saving space and effectively achieving negative pressure to ensure that the yarn end is sucked up.
[0116] A yarn clamp is used to hold the yarn tube.
[0117] The specific process of the yarn feeding device feeding the yarn is as follows:
[0118] The transferred bobbins surround the yarn head suction section in the negative pressure yarn feeding device 8, and the yarn head suction section sucks up a predetermined number of yarn heads from the bobbins.
[0119] According to the control signal, the tube feeding device 11 controls the robot arm 121 to move the airbag tube clamping assembly 123 horizontally, and controls the telescopic sleeve 122 to move the airbag tube clamping assembly 123 vertically until the airbag tube clamping assembly 123 is moved to the vicinity of the yarn head suction part in the negative pressure yarn feeding device 8.
[0120] The hollow sleeve covers the yarn end suction part in the negative pressure yarn feeding device 8 and sucks up the yarn end of the transferred bobbin yarn through negative pressure; at the same time, the yarn clamp holds the bobbin yarn, and at this time both the bobbin yarn and the yarn end are gripped by the airbag clamp assembly 123.
[0121] The tube feeding device 11 then controls the robot arm 121 to move the airbag tube clamping assembly 123 horizontally according to the control signal, and controls the telescopic sleeve 122 to move the airbag tube clamping assembly 123 vertically until the airbag tube clamping assembly 123 is moved to the winding machine yarn magazine.
[0122] When the bobbin is conveyed above the winding machine, the yarn clamp can release the bobbin, and the bobbin falls naturally and accurately into the yarn magazine of the winding machine (first predetermined storage area).
[0123] Then, the mounting plate moves downward under the drive of the robotic arm 121 and the telescopic sleeve 122. The yarn feeding device 11 then transports the adsorbed yarn ends through the hollow sleeve to the area above the second predetermined storage zone of the winding machine (the yarn storage negative pressure hole, which adsorbs yarn ends through negative pressure). The hollow sleeve then sprays air to blow the corresponding yarn ends of the yarn into the yarn storage negative pressure hole, which simultaneously adsorbs the yarn ends through negative pressure, ensuring that the yarn ends enter the yarn storage negative pressure hole. The first predetermined storage zone and the second predetermined storage zone are different areas; the first predetermined storage zone can be arranged around the second predetermined storage zone.
[0124] The control signal can be generated by the controller. In one embodiment, the airbag clamping tube assembly 123 can also be equipped with a camera unit. The camera unit will take pictures of the position of the winding machine in real time and transmit the pictures to the controller. The controller will analyze whether there is bobbin yarn in the yarn magazine of the winding machine in the picture. When it is determined that there is no bobbin yarn, the controller will generate a corresponding control signal to control the movement of the robot arm 121 and the telescopic sleeve 122, thereby controlling the airbag clamping tube assembly 123 to clamp or release the bobbin yarn.
[0125] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
