[0002] Chinese utility patent CN219525452U discloses a ball filling device for gravity winding. It is equipped with a pushing component to push the balls supported by the ball bearing support component into the material shaft supported by the material bearing support component. Since the length of the ball bearing support component is much smaller than the length of the material shaft, additional balls are needed during the ball filling process. The pushing component needs to move multiple times to complete the ball filling action. Utility Model Content

[0003] In view of the technical problems existing in the background art, the present invention aims to provide a self-weight ball filling winding device, which tilts the material shaft and uses the self-weight of the balls to complete the ball filling work.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This inclined ball-filling self-weight winding device includes a ball-filling mechanism, a winding mechanism, and a ball-turning mechanism. The ball-turning mechanism is located on the discharge side of the winding mechanism. The ball-filling mechanism includes a ball bearing support assembly and a ball bearing support assembly. The ball bearing support assembly forms a ball-filling channel with an inclined section. A ball-filling elevator connects the lower ball-turning mechanism and the upper ball bearing support assembly.

The ball bearing support assembly is connected to the winding mechanism and has a support shaft groove. The support shaft groove connects to the ball-filling channel and extends in the left-right direction.

[0005] In this scheme, the ball lifting mechanism lifts the balls from a low position to a high position and into the ball filling channel.

The ball filling channel extends in the front-back direction, and the ball lifting machine is inclined in the front-back direction and connects the ball filling channel and the ball pouring platform.

[0023] In this scheme, the balls have a certain speed in the left and right directions during the pouring process. The setting of the ball guide section allows the pouring cavity to have a certain space in the left and right directions and guides the balls to the ball outlet cavity. The balls reach the ball elevator through the ball outlet section and the ball outlet. The ball elevator lifts the balls to the ball filling channel and arranges them in the front and back directions, resulting in a compact structure.

[0024] Preferably, the bead-filling channels are distributed in a serpentine pattern.

[0042] See appendix Figure 1-2 4-8. In an embodiment of this invention, a self-weight bead-filling winding device includes a bead-filling mechanism 1, a winding mechanism 2, a bead-turning mechanism 3, and a discharge gripper 36. The bead-turning mechanism 3 is disposed on the discharge side of the winding mechanism 2, and the discharge seat 37 is configured to be raised, lowered, and moved horizontally.

[0043] The ball filling mechanism 1 includes a ball bearing support assembly 4 and a ball bearing support assembly 8. The ball bearing support assembly 4 forms a ball filling channel 5, which has an inclined section 6. The ball lifting machine 7 connects the lower ball turning mechanism 3 and the upper ball bearing support assembly 4. The ball lifting machine 7 includes a conveyor belt that is connected to a power source. The conveyor belt is provided with ball lifting plates at intervals. When the ball lifting plates pass through the ball outlet of the ball turning mechanism, a ball receiving cavity is formed. When the ball lifting plates pass through the ball inlet of the ball bearing support assembly 4, a ball discharge cavity is formed. The ball bearing support assembly 8 is connected to the winding mechanism 2. The ball bearing support assembly 8 forms a support shaft groove 9, which connects to the ball filling channel 5 and extends in the left-right direction.

[0044] The bead-turning mechanism 3 includes a bead-turning platform 25 and a lifting shaft assembly 26. The lifting shaft assembly 26 includes a fixed support plate 27 and a movable support plate 28. The movable support plate 28 is vertically adjustable. The fixed support plate 27 and the movable support plate 28 form a support groove. The discharge gripper 36 is connected to the lifting shaft assembly 26. The bead-turning platform 25 has an upward-opening bead-turning cavity 29. The cavity wall of the bead-turning cavity 29 has a bead-guiding section 30. The bead-turning platform 25 also has a bead-discharging cavity 32. 2 is connected to and located below the ball-out chamber 29. The ball-out chamber 32 has a ball-out section 33 in its wall. The ball-guide section 30 is inclined in the left-right direction. The ball-out section 33 is inclined in the front-back direction. The ball-out port 31 is located on the side wall of the ball-out chamber 32. The ball-out port 31 is connected to the ball-guide section 30. The ball-filling channel 5 extends in the front-back direction. The ball-rolling elevator 7 is inclined in the front-back direction and connects the ball-filling channel 5 and the ball-out stage 25.

[0045] In this embodiment, the direction of the ball bearings on the feed shaft is defined as from left to right, and the direction of the feed shaft from the winding mechanism 2 to the ball rewinding mechanism 3 is from front to back. After the feed shaft is finished by the winding mechanism 2, it is supported by the fixed support plate 27 and the movable support plate 28. The movable support plate 28 rises and lifts one end of the feed shaft, and the ball bearings roll out from the other end of the feed shaft and fall into the ball rewinding cavity 29. The ball bearings will bounce in the ball rewinding cavity 29, and finally fall into the ball outlet cavity 32 due to the guide section 30. After passing through the ball outlet section 33, they have a forward and backward speed and actively reach the ball lifting machine 7. They enter the ball receiving cavity one by one and are lifted. When passing through the ball inlet of the ball bearing support component 4, the ball receiving cavity is transformed into the ball outlet cavity. The ball bearings roll into the ball filling channel 5 through the ball inlet and finally reach the feed shaft.

[0046] The movable pallet 28 can be linearly raised and lowered by a cylinder, or it can be raised and lowered by a swinging motion. A swing arm is set to swing and drive the movable pallet 28 to rise and fall. The swing arm is fixedly connected to the rotating shaft. The rotation of the rotating shaft drives the swing arm to swing. After the ball is poured, it can be picked up by the gripper. Alternatively, the fixed pallet 27 and the movable pallet 28 can be designed as a fixed part and a movable part. The swing of the movable part makes the corresponding pallet 28 tilt into a straight line. The material shaft that has been wound up is automatically discharged due to gravity. The fixed pallet 27 and the movable pallet 28 form a V-shaped or U-shaped groove.

[0047] The cavity wall includes a bottom wall and side walls, and the bottom wall of the inverted bead cavity 29 has a bead guide section 30.

[0048] Specifically, the ball bearing elevator 7 consists of a chain, a sprocket assembly, and ball lifting plates. The ball lifting plates are spaced apart on the chain, and the chain is wound around the sprocket assembly. The sprocket assembly is connected to the power source for transmission.

[0049] The cross-section of the bead-filling channel 5 can be circular or square, and it can be a closed tube or an open groove.

[0050] The balls can queue up at the bottom of the ball lifting machine 7 and be lifted to the ball filling channel 5 by the ball lifting machine 7 during the filling process. At this time, the arrangement path is inclined so that the balls can automatically fill in the gaps. Alternatively, they can wait in the ball filling channel 5. The stop block at the outlet 35 of the ball filling channel 5 is removed to carry out the filling.

[0051] In other alternative embodiments, the ball lifting machine 7 can be set vertically, in which case the ball filling channel 5 or the ball turning mechanism 3 should be provided with a ball moving path extending forward and backward; the ball filling channel 5 can extend in the left and right direction, so that the balls have a left and right speed due to gravity and can directly enter the flat material shaft; the ball turning platform 25 can only be provided with the ball turning cavity 29, and the ball guide section 30 guides the balls to the ball lifting machine 7. The ball turning platform 25 can be tubular, and the ball guide section 30 is the inclined tube wall. The ball turning cavity 29 of the ball turning platform 25 can extend to the bottom of the shaft lifting assembly 26. The shaft lifting assembly 26 is installed on the ball turning platform 25, or it can be configured only at one end of the fixed support plate 27.

[0052] See appendix Figure 1-37. The winding mechanism 2 and the material bearing support assembly 8 are disposed between the two side wall panels. The material bearing support assembly 8 includes a support shaft platform 10, a front plate 11, and a rear plate 12. The front plate 11 and the rear plate 12 form a support shaft groove 9 that is wider at the top and narrower at the bottom. The front plate 11 and the rear plate 12 are mounted on the support shaft platform 10. Both ends of the support shaft platform 10 are hinged with lifting seats 13, and the corresponding first hinge shafts 14 extend in the front-rear direction. The lifting seats 13 are raised and lowered. A feeding cylinder 20 is provided on the lifting seat 13. The feeding cylinder 20 is connected to the support shaft platform 10. Equipped with a hinge 21, the hinge 21 is hinged to the support shaft 10 and the output shaft of the unloading cylinder 20 to form a third hinge shaft 22 and a fourth hinge shaft 23, respectively. The third hinge shaft 22 extends in the front-back direction, and the fourth hinge shaft 23 extends in the left-right direction. The first hinge shaft 14 is connected to a second hinge shaft, which extends in the left-right direction. The first hinge shaft 14 and the second hinge shaft are hinged to the support shaft 10 and the lifting seat 13, respectively. The unloading cylinder 20 drives the support shaft 10 to rotate around the second hinge shaft.

[0053] The bearing support 10 has a bearing receiving position and a bearing placing position. The two lifting seats 13 descend asynchronously to move the bearing support 10 from the bearing receiving position to the bearing placing position. During bead filling, the two ends of the bearing support 10 are vertically misaligned, and the two lifting seats 13 rise synchronously to move the bearing support 10 from the bearing placing position to the bearing receiving position.

[0054] The winding mechanism 2 includes a first winding assembly 15, which includes a first winding shaft 16 and a second winding shaft 17 that cooperate with each other. A first clamping plate 18 is provided between the first winding shaft 16 and the second winding shaft 17 and moves left and right.

[0055] A positioning plate 19 is provided in the bearing groove 9, which moves left and right. The positioning plate 19 is raised and lowered to allow the balls to pass through. A push plate 24 is provided in the bearing groove 9, which moves laterally. The ball filling channel 5 is distributed in a serpentine pattern. A telescopic stop is provided at the outlet 35 of the ball filling channel 5. The outlet 35 of the ball filling channel 5 is located at the end of the guide tube 34. The guide tube 34 is inclined. The outlet 35 of the ball filling channel 5 is higher than the bearing groove 9.

[0056] In this embodiment, after the shaft dropping mechanism drives the material shaft to fall into the shaft support groove 9, the positioning plate 19 and the push plate 24 push the material shaft to align. The positioning plate 19 rises, the single lifting seat 13 descends, the shaft support platform 10 rotates and tilts around the first hinge axis 14 and the third hinge axis 22, the stop block retracts, and the balls arranged in the ball filling channel 5 fall into the material shaft along the ball guide tube 34. After the ball filling is completed, the other end lifting seat 13 descends and the shaft support platform 10 completes the movement from the shaft receiving position to the shaft placing position. The unloading cylinder 20 actuates to lift the hinge member 21, and the shaft support platform 10 rotates around the fourth hinge axis 23 and the second hinge axis. The shaft support platform 10 tilts and pours the material shaft into the space between the first winding shaft 16 and the first winding shaft 16. The two first clamping plates 18 abut against the positioning plate 19 and the push plate 24 respectively to prevent the balls from falling out and the material shaft from shifting laterally.

[0057] Among them, the shaft dropping mechanism is a mature technology that can realize the dropping of a single material shaft; the shaft support table 10 can float along the axial direction of the second hinge shaft and the fourth hinge shaft 23 to adapt to the change of spacing in the left and right directions, and one end of the second hinge shaft and the fourth hinge shaft 23 is connected by a sleeve.

[0058] The balls can roll into the material shaft along the support groove 9 or fall directly into the material shaft; the stop block is connected to the cylinder output shaft, and an inclined plate is set in the ball storage chamber to form a ball filling channel 5. The cylinder is set on the wall of the ball storage chamber, and the power source is a mature technology, not limited to pneumatic and electric; the trajectory of the ball after leaving the guide tube 34 is a parabola. The design of the inclination and length of the guide tube 34 can control the lateral velocity component of the ball and the vertex of the parabola. The through hole on the wall plate is also considered as the guide tube 34.

[0059] The push plate 24 can be fixedly mounted on the bearing support 10. Correspondingly, a fixed first clamping plate 18 should be set to cooperate with the push plate 24. The lifting seat 13 is driven by a cylinder.

[0060] The winding mechanism 2 also includes a second winding assembly. The first winding assembly 15 performs pre-winding, and the second winding assembly performs winding. The material shaft moves from the first winding assembly 15 to the second winding assembly and exits from the second winding assembly. The material shaft can be poured out by the action of the two rollers that perform winding, or the material shaft can be pushed out by a pusher. A lifting and cutting assembly is provided between the first winding assembly 15 and the second winding assembly. This is a mature technology.

[0061] In other alternative embodiments, the material shaft is transferred to the first winding assembly 15 after bead filling, which can be achieved by its own weight. During bead filling, the material shaft is placed horizontally, the front plate 11 and / or the rear plate 12 move, and the material shaft loses support and falls due to gravity. A guide plate is provided to guide the material shaft to the first winding assembly 15. The guide plate can be connected to the front plate 11 or the rear plate 12 to form an operating space for the material shaft at the first winding assembly 15 to discharge. Alternatively, the material shaft support assembly 8 can include a lower support plate, a front baffle and a rear baffle. The support plate is movably set, and there is a gap between the front baffle and the rear baffle. During bead filling, the material shaft positioning block makes the end of the material shaft align with the outlet 35 of the bead filling channel 5. The support plate swings or is set on a rotating part to rotate around the rotation center, which allows the material shaft to lose support and fall due to gravity.

[0062] The above description represents the preferred embodiment of this utility model. It should be noted that the scope of protection of this utility model is not limited thereto. For those skilled in the art, various improvements, modifications, or equivalent substitutions can be made without departing from the equivalent inventive concept disclosed in this utility model, and these can also be considered as part of the scope of protection of this utility model.
