Description

Technical Field

[0001] The present application relates to the technical field of packaging equipment, and in particular to an automatic bearing packaging device and a packaging method. Background Art

[0002] The bearing is an important component used to support rotating or moving parts in machinery. Its main function is to reduce friction, support rotating parts, and ensure the smoothness and precision of movement. Bearings are usually composed of an inner ring, an outer ring, rolling elements (such as balls or rollers) and a cage. After the bearings are processed and manufactured, they need to be packaged to achieve the purpose of waterproofing, moisture-proofing, dust-proofing and preventing damage during transportation. At present, the packaging of bearing products generally adopts wrapping, which manually lays plastic cloth, kraft paper, waterproof tape, woven tape, self-adhesive tape, etc. layer by layer and wraps them around the bearings. This packaging method is labor-intensive and time-consuming, with low packaging efficiency and easy to break. Therefore, it is urgent to design a device that can package bearings.

[0003] For example, in the existing Chinese patent with publication number CN112046840B, an industrial bearing packaging device is disclosed, which includes a base, an electric push rod, a push mechanism, a sealing mechanism, and a blanking frame. A support frame is fixedly connected to one side of the top of the base; the electric push rod is installed on the top of the support frame; the push mechanism is arranged on the support frame, and the push mechanism is connected to the telescopic rod of the electric push rod; the sealing mechanism is arranged on the top of the base, and the sealing mechanism is connected to the telescopic rod of the electric push rod; the blanking frame is connected to the middle of the top of the base by bolts. Through the above-mentioned existing technology, the bearings can be packaged in plastic bags, and the plastic bags can be sealed immediately after packaging, so that the bearings are not easy to spread out during packaging.

[0004] However, the above prior art has the following technical defects:

[0005] When the above-mentioned prior art is used, four bearings are placed on the pushing mechanism, and a long plastic bag is put on the pushing mechanism. The electric push rod is started to drive the pushing mechanism to push the bearings onto the plastic bag, and the plastic bag containing the bearings falls onto the blanking frame. Then the electric push rod drives the sealing mechanism to operate and seal the plastic bag; when performing the sealing operation, the staff needs to flatten the plastic bag and place it under the sealer to achieve a better sealing effect. When the above-mentioned device is in operation, one or more bearings are loaded into the plastic bag at one time and the sealing is completed before the next group of bearings can be packaged. The equipment cannot handle multiple operations at the same time, and it is necessary to wait for the previous group of packaging to be completed before subsequent operations can be carried out, which leads to low packaging efficiency, especially when the bearings are packaged separately. In addition, during the process of sealing the plastic bag, personnel are required to assist in flattening the plastic bag and placing it under the sealer, so that the degree of automation of the equipment is low, which further increases the work intensity and fatigue of the personnel.

[0006] Secondly, the above-mentioned prior art packages bearings in long plastic bags and seals them. The plastic bags are easily damaged during transportation, so that they cannot achieve the waterproof, moisture-proof, dust-proof and other effects. They are also easily damaged during the unpacking process, making them difficult to recycle and reuse. They are not environmentally friendly and have high packaging costs.

[0007] Based on this, on the basis of the existing industrial bearing packaging equipment, in order to overcome the above-mentioned technical defects, there is still room for improvement. Summary of the invention

DETAILED DESCRIPTION

[0048] The following is combined with Figure 1-Figure 18 This application is described in further detail.

[0049] The embodiment of the present application discloses an automatic bearing packaging device and a packaging method, which can perform independent closed packaging operations on multiple bearings at the same time, improve the waterproof, moisture-proof, and dust-proof properties of the bearings after packaging, and reduce the occurrence of easy damage during transportation. The present application provides an automatic bearing packaging device and a packaging method.

[0050] Embodiment 1:

[0051] Reference Figures 1 to 3As shown, in the first aspect, the present application provides an automatic bearing packaging device, including an operating table 1 and a support plate 11 installed on one side of the operating table 1. A bottom support rod 12 is arranged at the lower side of the operating table 1, and a servo motor 13 is arranged in the middle of the bottom support rod 12. It should be noted that the servo motor 13 is set to stop running every 120 degrees of rotation. A packing device 2 is arranged on the operating table 1; it is used to cooperate with the servo motor 13 to perform independent closed packaging operations on multiple bearings.

[0052] The packaging device 2 includes an annular inner plate 21 rotatably mounted on the operating table 1, and the annular inner plate 21 is connected to the rotating end of the servo motor 13. An annular groove 100 for installing the annular inner plate 21 is opened on the operating table 1. The operation of the servo motor 13 can drive the annular inner plate 21 to rotate in the annular groove 100. Each time the servo motor 13 is started, the annular inner plate 21 will be driven to rotate 120 degrees; and the operating table 1 is provided with a No. 1 position 101, a No. 2 position 102 and a No. 3 position 103 in sequence. In this embodiment, three active cylinders 22 are preferably arranged vertically and equidistantly on the annular inner plate 21. It should be noted that each time the servo motor 13 drives the annular inner plate 21 to rotate once and stops, the three active cylinders 22 will accurately stop at the No. 1 position 101, the No. 2 position 102 and the No. 3 position 103 respectively.

[0053] A supporting rod 23 is installed in the middle of the working cylinder 22, a packing 24 for packing bearings is placed on the support plate 11, and a locking mechanism 3 for clamping the upper and lower sides of the packing 24 is provided on the working cylinder 22. The operating table 1 is located at the third position 103 and is provided with a buckle unit 4. When in use, the staff is located at the first position 101, takes a packing 24 from the support plate 11 and turns it inside out, and puts it on the working cylinder 22 at the first position 101 with the inside facing out, and then puts the bearing sleeve outside the packing 24, and the supporting rod 23 supports the bearing (such as Figure 3 As shown). The locking mechanism 3 can clamp the upper and lower sides of the package 24, and the servo motor 13 is running to transfer the action cylinder 22 originally at the No. 1 position 101 with the package 24 and the bearing to the No. 2 position 102 and the No. 3 position 103 in turn. The package 24 is packaged on the bearing from bottom to top and from top to bottom in turn. When the action cylinder 22 is transferred from the No. 3 position 103 back to the No. 1 position 101 again, all the packaging steps of the bearing are completed. At this time, the staff can remove the packaged bearing and then put the package 24 and the bearing again.

[0054] That is, every time the servo motor 13 rotates, a packaged bearing will be transferred from the third position 103 to the first position 101. All the staff needs to do is to remove the packaged bearing and then place the new package 24 and the bearing sleeve on the working cylinder 22 at the first position 101. At the same time, the second position 102 and the third position 103 are operating automatically. The second position 102 will package the package 24 on the bearing from bottom to top, while the third position 103 will package the package 24 on the bearing from top to bottom. With the operation of one staff member, assembly line operation is realized, which improves the efficiency of independent packaging of bearings.

[0055] Reference Figure 3 As shown, specifically, in order to be able to perform closed packaging of the bearing, further improve the waterproof, moisture-proof and anti-breakage performance, and also have environmental protection and reusable characteristics, the packaging 24 is a composite cloth made of inner and outer PE materials and middle layer PET materials, and is made into a cylindrical shape. The packaging 24 has a tightening part 241 at both ends, and an elastic band is provided at the tightening part 241, and the tightening effect is achieved through the elastic band. When making the specific packaging 24, the two materials of PE and PET are first heat-sealed to make a composite cloth, and then the heat-sealed composite cloth is divided into strips, and then the stripped composite cloth is cross-cut into pieces, and then the cross-cut composite cloth is heat-sealed to form a cylindrical shape, and finally elastic bands are provided at the upper and lower ends of the cylindrical shape to form a tightening part 241, and the above is to complete the production of the packaging 24 used.

[0056] Reference Figure 4 and Figure 5 As shown, considering the need to clamp and lock the upper and lower sides of the packaging material 24 in different states, so as to facilitate the subsequent automated packaging operation of the bearing, the locking mechanism 3 includes a clamping cylinder 32 movably arranged on the upper end of the working cylinder 22 through a spring rod 31, the spring rod 31 is fixedly installed on the upper end of the working cylinder 22, and the top end of the clamping cylinder 32 is fixedly connected to the telescopic end of the spring rod 31; in this embodiment, four supporting blocks 33 are preferably installed at the bottom end of the clamping cylinder 32, and the working cylinder 22 is provided with an income groove 221 adapted to the supporting blocks 33. Under the drive of the spring rod 31, the bottom side of the clamping cylinder 32 will always be tightly pressed against the upper side of the working cylinder 22. When the clamping cylinder 32 is pulled upward, the four supporting blocks 33 are synchronously driven to rise, and a gap is formed between the clamping cylinder 32 and the working cylinder 22. A magnet disc 34 is installed at the upper end of the clamping cylinder 32, and the magnet disc 34 is fixedly connected to the clamping cylinder 32.

[0057] The side wall of the action cylinder 22 located below the support rod 23 is symmetrically embedded with an arc-shaped magnet 35, and the action cylinder 22 is provided with an arc-shaped groove 222 for installing the arc-shaped magnet 35. The action cylinder 22 is provided with a metal ring 36 that attracts the arc-shaped magnet 35. In this embodiment, four outer support rods 37 are preferably provided on the outer wall of the metal ring 36. After the staff puts the package 24 on the action cylinder 22, they lift the clamping cylinder 32 and insert the upper edge of the package 24 into the gap between the clamping cylinder 32 and the action cylinder 22, and then release the clamping cylinder 32. The clamping cylinder 32 can clamp the upper edge of the package 24 under the drive of the spring rod 31 to achieve the purpose of locking the upper edge of the package 24, so as to facilitate the bearing sleeve outside the package 24.

[0058] Reference Figure 6 and Figure 7 As shown, a middle plate 39 is provided on the outer support rod 37 through the bottom seat 38 to limit the sliding. A sliding groove 371 is provided on the outer support rod 37 for the bottom seat 38 to be installed. A terminal plate 311 is provided on the middle plate 39 through the inner shaft 310 to rotate. A connecting hole 391 is provided on the middle plate 39 for the inner shaft 310 to be installed. A reset torsion spring 312 is sleeved on the inner shaft 310. A limit side rod 313 is installed on one side of the terminal plate 311. The reset torsion spring 312 always has a driving force to drive the terminal plate 311 to rotate away from the action cylinder 22. However, due to the limitation of the limit side rod 313, the terminal plate 311 can always maintain a vertical state without the action of other external forces. When the bottom seat 38 is driven by external force, it can drive the middle plate 39 and the terminal plate 311 to slide synchronously on the outer support rod 37.

[0059] Reference Figure 7As shown, since it is necessary to automatically clamp and release different positions of the bottom edge of the package 24 synchronously, a clamp 5 is provided on the terminal plate 311, and the clamp 5 includes a locking electromagnet 51 embedded in one side of the terminal plate 311, and a rectangular groove 314 for installing the locking electromagnet 51 is provided on the terminal plate 311. A metal lock block 53 is slidably provided on the side of the terminal plate 311 facing the action cylinder 22 through two limit rods 52, and a sliding plug hole 315 for installing the two limit rods 52 is provided through the terminal plate 311, and a reset spring 54 connected to the side wall of the terminal plate 311 is sleeved on the limit rod 52. The reset spring 54 always has a driving force to push the metal lock block 53 to slide toward the action cylinder 22, that is, a driving force to slide away from the locking electromagnet 51. It should be noted that the suction force generated by the locking electromagnet 51 on the metal lock block 53 after power is turned on is greater than the force of the reset spring 54. After the staff puts the package 24 on the working cylinder 22, they need to pay attention to placing the bottom of the package 24 between the metal locking blocks 53 and the edge locking electromagnets 51 on the four outer support rods 37. After the bearing sleeve is placed on the package 24, the edge locking electromagnets 51 are energized at the same time, and the metal locking blocks 53 can clamp the bottom edge of the package 24 under the action of suction. The metal locking blocks 53 and the edge locking electromagnets 51 at four different positions on the four outer support rods 37 can achieve the effect of clamping the bottom edge of the package 24 from different directions.

[0060] Reference Figures 8 to 10 As shown, in order to be able to simultaneously stretch the bottom edge of the packaging material 24 outward from different directions and wrap it around the bearing from bottom to top, an extension piece 6 is provided on the action cylinder 22, and the extension piece 6 includes a push ring 61 slidably mounted on the bottom of the action cylinder 22. In this embodiment, four connecting push rods 62 are hingedly arranged on the outer wall of the push ring 61, and the four connecting push rods 62 are respectively connected to the bottom connecting seats 38 slidably arranged on the four outer support rods 37. Two bottom side electric push rods 64 are installed at the second position 102 on the lower side of the operating table 1 through the lifting rod seat 63. The operating table 1 has assembly holes 104 adapted to the two bottom side electric push rods 64, and a circular through hole 211 for the bottom side electric push rod 64 to extend into is opened on the annular inner plate 21 below the push ring 61. It should be noted that, since three action cylinders 22 are mounted on the annular inner plate 21 and a push ring 61 is sleeved on the bottom of each action cylinder 22 , the annular inner plate 21 has three groups of circular through holes 211 extending therethrough.

[0061] After the upper and lower edges of the package 24 are clamped, the servo motor 13 is started to operate, so that the action cylinder 22 originally in the No. 1 position 101 with the package 24 and the bearing placed thereon is transferred to the No. 2 position 102, and the two bottom side electric push rods 64 are started to rise. After the telescopic ends enter and pass through the round through hole 211, they will conflict with the bottom side of the push ring 61, thereby pushing the push ring 61 to move upward. In addition, since the metal ring 36 is attracted to the arc-shaped magnet 35 in the initial state and will not move upward temporarily, the bottom connecting seat 38 will be driven by the connecting push rod 62, pushing the bottom connecting seat 38 to slide away from the action cylinder 22, and cooperating with the metal locking block 53 and the locking electromagnet 51 to clamp the bottom edge of the package 24, thereby achieving the effect of synchronously stretching the package 24 in four different directions. It should be noted that the return torsion spring 312 sleeved on the inner circular shaft 310 has a relatively large force. Although the tightening portion 241 is provided with an elastic band, the terminal plate 311 will not rotate inward at this time.

[0062] When the bottom of the package 24 is stretched to the limit and the diameter is larger than the outer diameter of the bearing, driven by the two bottom electric push rods 64, the push ring 61 continues to move upward, forcing the metal ring 36 to separate from the arc magnet 35 and move upward, and the bottom seat 38 has a certain damping when sliding in the slide slot 371, so that the tightening force of the tightening part 241 will not drive the bottom seat 38 to slide and reset in the direction of the action cylinder 22, and the bottom edge of the package 24 will still remain in the stretched state. When the metal ring 36 moves upward, the package 24 in the stretched state can be wrapped on the bearing from bottom to top, until the bottom of the package 24 is completely covered on the bearing and can no longer move upward, and the terminal plate 311 is restricted and can rotate; the locking electromagnet 51 is powered off, and the metal lock block 53 can release the clamping of the bottom edge of the package 24 under the drive of the reset spring 54. This can achieve the effect of automatically stretching and expanding the bottom of the package 24 from bottom to top and wrapping it on the bearing.

[0063] The two bottom side electric push rods 64 shrink and reset and withdraw from the round hole 211. The metal ring 36 and the push ring 61 move downward and reset under the action of their own weight. The metal ring 36 returns to the arc-shaped magnet 35 and attracts it. It should be noted that since the bottom connection seat 38 has damping in the slide groove 371, when the metal ring 36 and the arc-shaped magnet 35 are attracted and locked, the push ring 61 will slide downward and reset under the action of its own weight, and drive the corresponding bottom connection seat 38 to slide and reset through the four connecting push rods 62. At this time, the two bottom side electric push rods 64 have been withdrawn from the round hole 211, so that the servo motor 13 can start and drive the annular inner plate 21 to rotate again, so that the bearing that was originally in the second position 102 and has completed the bottom outsourcing continues to move to the third position 103.

[0064] Reference Fig.11As shown, considering that after completing the packaging operation of the bearing from bottom to top, it is necessary to wrap the upper side of the packaging material 24 on the bearing from top to bottom to achieve the purpose of closed packaging, the buckle unit 4 includes an L-shaped assembly rod 41 installed on the outer wall of the operating table 1, and an end top ring plate 42 is clamped on the L-shaped assembly rod 41, and the end top ring plate 42 and the L-shaped assembly rod 41 are fixedly connected; an annular electromagnet 43 matching the magnet disc 34 is installed on the L-shaped assembly rod 41, and an electric push rod 45 is arranged on one side of the L-shaped assembly rod 41 through a sleeve rod seat 44, and an outward expansion component 7 is arranged at the telescopic end of the electric push rod 45, which can synchronously push the upper side of the packaging material 24 outward from different directions. After the action cylinder 22 is transferred to the third position 103, the annular electromagnet 43 is first started and energized. The position where the clamping cylinder 32 stays is just below the annular electromagnet 43. The annular electromagnet 43 after being energized will generate suction force on the magnet disc 34, and the suction force is greater than the force of the spring rod 31 on the clamping cylinder 32, thereby pulling the clamping cylinder 32 upward to achieve the purpose of releasing the clamping lock on the upper side of the package 24. When the clamping cylinder 32 moves upward, the four supporting blocks 33 installed on the lower side of the clamping cylinder 32 will move upward synchronously to push the upper side of the package 24 in the gap outward, so that the upper side of the package 24 is separated from the gap between the clamping cylinder 32 and the action cylinder 22. This is to facilitate the subsequent expansion operation in coordination with the external expansion component 7.

[0065] Reference Fig.12 and Fig.13 As shown, since the upper side of the packaging 24 needs to be propped open so that it can be sleeved on the bearing, the expansion assembly 7 includes a base ring 70 installed on the telescopic end of the electric push rod 45. In this embodiment, four rectangular end seats 71 are equidistantly embedded on the base ring 70, and a rectangular groove 701 for installing the rectangular end seats 71 is opened on the base ring 70. Two rectangular side rods 72 are inserted and slidably provided on the rectangular end seat 71, and an insertion hole 711 is opened through the rectangular end seat 71 for installing the rectangular side rods 72. The contraction of the electric push rod 45 can drive the base ring 70 and the four rectangular end seats 71 on the base ring 70 to move downward.

[0066] Reference Fig.14 and Fig.15As shown, an L-shaped hook rod 73 is installed between the two rectangular side rods 72, and a U-shaped rod 75 is slidably provided at the hooking end of the L-shaped hook rod 73 through the end plug rod 74. A round plug hole 730 adapted to the end plug rod 74 is penetrated on the L-shaped hook rod 73, and a downward spring 76 is sleeved on the end plug rod 74. The end plug rod 74 and the U-shaped rod 75 are fixedly connected, and the downward spring 76 always has a driving force to push the U-shaped rod 75 downward, but due to the end limit of the end plug rod 74, the U-shaped rod 75 will not be separated from the L-shaped hook rod 73; the four support blocks 33 push the upper edge of the package 24 outward to ensure that the U-shaped rod 75 at the hooking end of the L-shaped hook rod 73 is inserted into the edge of the package 24. A pulling spring 77 is provided between the L-shaped hook rod 73 and the rectangular end seat 71, and the pulling spring 77 always has a driving force to pull the L-shaped hook rod 73 to slide in the direction of the rectangular end seat 71. The rectangular end seat 71 is provided with a receiving circular hole 712 for the pull spring 77 to be contracted and installed, a positioning electromagnet 78 is provided on the upper side of the rectangular end seat 71, and a hinged connecting rod 79 is provided on the L-shaped hook rod 73 and the rectangular end seat 71, and the hinged connecting rod 79 is made of metal. It should be noted that the hinged connecting rod 79 is composed of two connecting rods and the ends are hingedly assembled.

[0067] In the initial state, the positioning electromagnet 78 is energized, and affected by the resistance of the end top ring plate 42, the hinged link 79 is close to a parallel state, and a part of the hinged link 79 is in contact with the positioning electromagnet 78. The energized positioning electromagnet 78 has a suction force on the metal hinged link 79, and the suction force is greater than the force of the pulling spring 77. Therefore, when the electric push rod 45 drives the base ring 70 to move downward, due to the locking of the hinged link 79 by the positioning electromagnet 78, even if the hinged link 79 does not conflict with the end top ring plate 42, it is still close to a parallel state, and the distance between the U-shaped rod 75 and the rectangular end seat 71 is at the maximum state.

[0068] When the electric push rod 45 drives the base ring 70 to move downward, the U-shaped rods 75 at different positions can be stuck at the upper port of the package 24, and the positioning electromagnet 78 is turned off. The L-shaped hook rod 73 will drive the U-shaped rod 75 to slide toward the rectangular end seat 71 under the drive of the pull spring 77, and the hinged connecting rod 79 will bulge upward, thereby achieving the effect of stretching the upper side of the package 24 outward until the diameter of the package 24 is larger than the outer diameter of the bearing. The force of the downward spring 76 is relatively large, and even if the U-shaped rod 75 is hooked at the port of the package 24, the electric push rod 45 drives the base ring 70 to move downward, and the U-shaped rod 75 will not slide upward due to the resistance of the package 24. Until the expanded upper side of the packaging material 24 is completely covered on the bearing from top to bottom and cannot be covered any further, at this time, under the force of resistance, the U-shaped rod 75 will slide up at the end of the L-shaped hook rod 73, causing the downward spring 76 to contract until the bottom end of the U-shaped rod 75 is flush with the bottom side of the L-shaped hook rod 73, ensuring that the upper side of the packaging material 24 can be smoothly separated from the U-shaped rod 75, so as to release the hooking state of the upper side of the packaging material 24, so that the packaging material 24 can be smoothly covered on the bearing. At this point, all steps of the closed packaging operation of the bearing are completed. When the action cylinder 22 of the third position 103 is transferred to the first position 101, the staff can remove the packed bearing.

[0069] When the electric push rod 45 drives the base ring 70 to move up and reset, the raised hinged link 79 will come into contact with the lower side of the end top ring plate 42, thereby driving the hinged link 79 to return to its initial state and re-energizing the positioning electromagnet 78 to lock the hinged link 79, thereby achieving the purpose of restoring the initial state.

[0070] Embodiment 2:

[0071] Reference Fig.16 and Fig.17 As shown, on the basis of the first embodiment, in order to support bearings of different diameters, an adjustment control 8 for adjusting the support rod 23 is provided in the middle of the working cylinder 22, and the adjustment control 8 includes a support rod 23 symmetrically limited and slidably arranged in the middle of the working cylinder 22 through a dovetail bar 81, and a dovetail slot 223 for installing the dovetail bar 81 is symmetrically opened in the middle of the working cylinder 22, and a transmission rack 82 is provided on one side of the two support rods 23. It should be noted that the transmission rack 82 is fixedly installed on the bearing On one side of the supporting rod 23; a driving gear 84 meshing with the two transmission racks 82 is rotatably installed in the middle of the working cylinder 22 through the inner rotating shaft 83, and a central opening 224 for installing the inner rotating shaft 83 and the driving gear 84 is opened in the middle of the working cylinder 22, a limiting plug rod 85 is inserted on one of the supporting rods 23, and six limiting plug holes 231 for inserting and installing the limiting plug rod 85 are equidistantly opened on one of the supporting rods 23, and a positioning hole 225 adapted to the limiting plug rod 85 is opened in the middle of the working cylinder 22.

[0072] In the actual packaging process, when it is necessary to package bearings with larger diameters, in order to support them, before putting the packaging material 24 on the action cylinder 22, the supporting length of the two supporting rods 23 is adjusted. Specifically, the limiting rod 85 is first pulled upward to disengage it from the positioning hole 225 to release the lock on the supporting rod 23, and then one of the supporting rods 23 is pulled, and under the action of the transmission rack 82 and the driving gear 84, the other supporting rod 23 slides synchronously in the opposite direction. After adjusting to a suitable length, the limiting rod 85 is inserted into the positioning hole 225 to lock the supporting rod 23 again, so that the length of the two supporting rods 23 can be adjusted, and bearings with larger diameters can be supported.

[0073] Reference Fig.18 As shown, on the other hand, the present application also discloses a bearing automatic packaging method, the packaging method comprises the following steps:

[0074] The first step is to place the material: take the package 24 on the pallet 11, turn it inside out and place it on the working cylinder 22 at the No. 1 position 101, then put the bearing on the package 24, and the supporting rod 23 holds up the bearing; during the specific operation, the staff stands at the No. 1 position 101, takes a package 24 from the pallet 11 and turns it outside out, places it on the working cylinder 22 at the No. 1 position 101 with the inside out, and then puts the bearing on the outside of the package 24, and the supporting rod 23 can support the bearing.

[0075] The second step is to lock the port: lift up the clamping cylinder 32 to lock the upper side of the package 24, and the locking mechanism 3 operates to clamp the lower side of the package 24 in multiple directions; specifically, after the package 24 is put on the working cylinder 22, lift up the clamping cylinder 32 to insert the upper side of the package 24 into the gap between the clamping cylinder 32 and the working cylinder 22, and then release the clamping cylinder 32 to clamp the upper side of the package 24; finally, it is necessary to place the bottom of the package 24 between the metal locking blocks 53 and the locking electromagnet 51 on the four outer support rods 37, and the locking electromagnet 51 is energized. Under the action of suction, the metal locking block 53 can clamp the bottom side of the package 24.

[0076] The third step is to wrap the bottom side outward: the servo motor 13 drives the annular inner plate 21 to rotate, and the active cylinder 22 at the No. 1 position 101 is transferred to the No. 2 position 102. The bottom side of the package 24 is expanded synchronously in multiple directions through the edge locking mechanism 3, and the bearing is wrapped from bottom to top; the two bottom side electric push rods 64 are started, so that their telescopic ends pass through the round through holes 211 and contact with the push ring 61 and push the push ring 61 to move upward. Under the action of the connecting push rod 62, the bottom connecting seat 38 can be pushed to slide away from the active cylinder 22, so as to achieve the purpose of stretching the bottom side of the package 24.

[0077] When the bottom edge of the package 24 is stretched to the limit and the diameter is larger than the outer diameter of the bearing, the metal ring 36 is forced to separate from the arc-shaped magnet 35 and move upward, so that the package 24 is wrapped around the bearing from bottom to top. The edge locking electromagnet 51 is powered off, and the clamping of the bottom edge of the package 24 is released. The effect of automatically stretching the bottom edge of the package 24 from bottom to top and wrapping it around the bearing is achieved.

[0078] Step 4: Upper side wrapping: When the action cylinder 22 is transferred to the third position 103 under the operation drive of the servo motor 13, the lower buckle unit 4 operates to release the lock on the upper side of the package 24, and expand the package 24 from top to bottom and wrap it on the bearing. Specifically, the electric push rod 45 drives the base ring 70 to move downward, so that the U-shaped rods 75 in different directions are stuck at the upper port of the package 24, and then the positioning electromagnet 78 is powered off. Under the drive of the pull spring 77, the L-shaped hook rod 73 will drive the U-shaped rod 75 to slide, stretching the upper side of the package 24 outward. The electric push rod 45 continues to drive the base ring 70 downward to wrap the expanded package 24 from top to bottom on the bearing. At this time, under the force of the resistance, the U-shaped rod 75 will slide up and the probe spring 76 will contract to ensure that the upper side of the package 24 can be smoothly separated from the U-shaped rod 75, and the hooking state of the upper side of the package 24 is released, so that the package 24 can be smoothly wrapped on the bearing. In the event of a power outage or damage to the equipment, the staff can also manually operate the packaging material 24, directly put it one-to-one on the outer diameter of the bearing, then insert part of the packaging material 24 into the inner diameter of the bearing and pull it out, then repeat the process of putting it on the outer diameter of the bearing and automatically lock it, thus completing the individual packaging of the bearing.

[0079] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
