Description

Technical Field

[0001] The invention relates to the field of storage of guide sleeves, and in particular to a multi-station storage system for guide sleeves. Background Art

[0002] As an important component in the hydraulic system, the guide sleeve mainly plays a supporting role and ensures the good coaxiality of the piston rod and the cylinder. For the hydraulic cylinder, the material collection and loading and unloading of the guide sleeve are the initial and important processes in the entire assembly process. In the traditional assembly method, the storage and loading and unloading of the guide sleeve are completed manually, which requires a lot of manpower, is time-consuming and labor-intensive, and has low work efficiency.

[0003] In recent years, with the rapid development of industrial automation and intelligence, the storage and assembly of parts have gradually changed from the original manual handling (that is, workers use material carts or baskets to carry) to efficient and highly automated intelligent storage. The existing storage systems mainly include dot matrix silos, circular rotary silos, annular rotary silos, plate chain silos, chain silos, belt silos, jacking silos and dial silos. Combined with the actual production requirements of the guide sleeve, the annular rotary silo is preferred for storage and loading and unloading operations of the guide sleeve. However, the existing annular rotary silos generally have the following problems:

[0004] First of all, the existing annular rotary silos generally need to cooperate with industrial robots to complete the loading and unloading of parts. This has high requirements on the technology of robot equipment, high equipment investment cost and expensive operating cost, and also has high requirements on the working space. There are disadvantages such as large footprint and inconvenient movement.

[0005] Secondly, in actual production, there are many types of guide sleeves, so the automation equipment needs to be able to adapt to a variety of different sizes and types of products and have a certain degree of flexibility. However, most of the existing silos are suitable for the storage of a single model of guide sleeves, with poor versatility, further increasing the equipment investment cost of manufacturers.

[0006] When a factory updates or changes its products, it means that the material handling fixture needs to be redesigned, which further increases costs and prolongs the changeover time.

[0007] Furthermore, the storage mechanism shakes during the rotation and feeding process, which poses a certain threat to the surface of the guide sleeve. The guide sleeve is a precision component, and when its surface is damaged, it will inevitably affect the assembly quality of the hydraulic cylinder. Therefore, there is a probability of scrapping parts during the rotation and feeding of the existing silo, which in turn prolongs the assembly time of the hydraulic cylinder and increases unnecessary workload.

[0008] In view of this, the present invention provides a multi-station storage system for guide sleeves, which can not only realize the stable transportation of the guide sleeves, but also realize the smooth loading, unloading and unloading of the guide sleeves.

[0061] The following is a detailed description of an embodiment of the present invention in conjunction with the accompanying drawings. This embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation method and a specific operation process are given, but the protection scope of the present invention is not limited to the following embodiment.

[0062] Combination Figure 1-3 It can be seen that the multi-station storage system for guide sleeves described in the present invention includes a frame 10, a material storage structure, a rotary conveying mechanism 20, a lifting and loading mechanism 30 and a material taking mechanism 40. The frame 10 has a working platform 101 to facilitate the installation of the rotary conveying mechanism 20, the lifting and loading mechanism 30 and the material taking mechanism 40. In addition, during actual installation, a dust cover 102 is provided above the working platform 101. Figure 1 As shown; the rotary conveying mechanism 20 is arranged on the working platform 101, including a first power source arranged below the working platform 101, a pair of transmission wheels 201 arranged at intervals on the working platform 101, and a power output part wound around the two transmission wheels 201; the material storage structure has a plurality of material storage racks 50 for containing the guide sleeves, and the plurality of material storage racks 50 are evenly spaced and arranged on the power output part. After the first power source is started, the material storage racks 50 are driven to be transported in a circular direction through the transmission wheels 201 and the power output part;

[0063] The right end of the working platform 101 is a material taking station. The lifting and loading mechanism 30 is arranged on the working platform 101 at the material taking station, and the lifting and loading mechanism 30 is located below the working platform 101. The pusher unit of the lifting and loading mechanism 30 can push the guide sleeve in each material storage rack 50 upwards, laying a foundation for taking materials.

[0064] The material picking mechanism 40 is mounted on the working platform 101. The clamping mechanism 401 of the material picking mechanism 40 can move above the material picking station. A pair of material picking clamps 401a of the clamping mechanism 401 are open and close structures, which can meet the clamping requirements of guide sleeves of different sizes and have a wide range of applications. Even if the product is iterated, it can be applied to new guide sleeves.

[0065] Combination Figure 2-3 It can be seen that the first power source is the motor reducer 202 arranged below the working platform 101; the transmission wheel 201 is a transmission gear rotatably arranged on the working platform 101, and the two transmission gears are located above the working platform 101, and the power output part is a conveying chain 203 in an annular structure wound around the two transmission gears. When working, the motor reducer 202 drives one of the transmission gears to rotate to realize the rotation of the annular conveying chain 203, so that multiple storage racks 50 are conveyed in an annular manner on the working platform 101 driven by the conveying chain 203, that is, the present invention is an annular storage.

[0066] Combination Figure 4-6 It can be seen that the material storage rack 50 includes a base 501, an opening and closing adjustment assembly arranged on the base 501, a supporting member for supporting the guide sleeve and a limiting unit for storing the guide sleeve, and the limiting unit and the supporting member form a material storage tank. Among them, the supporting member is a horizontally arranged supporting plate 502, and the limiting unit has not only a limiting function but also a guiding function, which guides the supporting plate 502; the opening and closing adjustment assembly includes an adjustment rod 503 with two ends mounted on the base 501 through a bearing seat and a pair of adjustment members (i.e., adjustment seats 504) arranged on the adjustment rod 503 with opposite moving directions, and the adjustment seats 504 are arranged oppositely.

[0067] The limiting unit includes a pair of fixed rods 505 fixed on the base 501 and four movable rods 506, the distance between the two fixed rods 505 is greater than the diameter of the guide sleeve; two vertical movable rods 506 are fixed on each adjustment seat 504, and the movable rods 506 on the two adjustment seats 504 are arranged opposite to each other. When in use, the distance between the upper movable rods 506 can be adjusted by screwing the adjustment rod 503, thereby meeting the storage requirements of guide sleeves of different sizes, with a wide range of applications and high flexibility.

[0068] During actual installation, the supporting plate 502 is passed through the fixed rod 505 and the movable rod 506. Since the movable rod 506 can be opened and closed, a strip-shaped perforation corresponding to the movable rod 506 is opened on the supporting plate 502 to provide a movable space for the movable rod 506.

[0069] In one embodiment of the present invention, in combination Figure 4-6 It can be seen that the adjustment rod 503 is preferably a forward and reverse adjustment screw, and the adjustment rod 503 has a pair of connecting nuts with opposite moving directions, and each connecting nut is fixedly connected to an adjustment seat 504. During operation, since the positive and reverse threads of the adjustment rod 503 are both provided with connecting nuts, the two connecting nuts can be rotated in opposite directions and in opposite directions by rotating the adjustment rod 503, and the operation is simple and convenient;

[0070] The opening and closing adjustment assembly further includes a pair of guide units, which are located on both sides of the adjustment rod 503, and each adjustment seat 504 is connected to the two guide units to ensure the smooth operation and movement accuracy of the adjustment seat 504.

[0071] In this embodiment, the guide unit preferably has the following structure: Figure 4-6 As shown, the guide unit includes a guide shaft 507 mounted on the base 501 and two slides 508 slidably mounted on the two guide shafts 507, and each slide 508 is fixedly connected to one of the adjustment seats 504. This means that two slides 508 are fixedly connected below each adjustment seat 504 to ensure the smooth operation and motion accuracy of the adjustment seat 504. In addition, the guide shaft 507 is an optical axis, and the slide 508 is preferably slidably mounted on a linear bearing of the guide shaft 507 to reduce friction and improve motion accuracy.

[0072] In actual installation, Figure 4-6 As shown, two pairs of running wheels 509 running on the working platform 101 are also provided at the bottom of the base 501, so that each storage rack can move circumferentially on the working platform under the action of the annular conveyor chain, thereby realizing the loading and unloading of each storage rack.

[0073] Combination Figure 7-8 It can be seen that the lifting and loading mechanism 30 also includes a base 301 arranged below the working platform 101, a first power mechanism arranged on the base 301, and a lifting member driven by the first power mechanism, and the pusher unit is arranged on the lifting member. When working, the first power mechanism drives the pusher unit to rise and fall through the lifting member to achieve stable lifting of the guide sleeve.

[0074] Specifically, the first power mechanism is a synchronous belt transmission pair driven by a first motor 302 and a transmission screw 303 fixedly connected to the synchronous belt transmission pair, and the transmission screw 303 is arranged vertically; the lifting member is a lifting plate 304 horizontally arranged below the base 301, and the lifting plate 304 is fixedly connected to the first nut of the transmission screw 303;

[0075] The pusher unit includes four material picking push rods 305 arranged at the corners of the lifting plate 304. The material picking push rods 305 are arranged vertically. The working platform 101 and the base 501 of each storage rack 50 are provided with through holes corresponding to the material picking push rods 305 one by one, ensuring that the material picking push rods 305 can pass through the working platform 101 and the base 501 to lift the supporting plate 502 to realize the loading of the guide sleeve.

[0076] In order to ensure the movement accuracy of each material picking push rod 305, a limiting guide sleeve 306 corresponding to each material picking push rod 305 is fixedly connected to the base 301. The material picking push rod 305 passes through the limiting guide sleeve 306, which not only has a limiting function, but also has a guiding function to ensure the pushing accuracy of the material picking push rod 305. In addition, the present invention uses four material picking push rods 305 to act on the four corners of the support plate 502, so that the support plate 502 is balanced in force, avoiding the guide sleeve from being skewed during the feeding process, and avoiding the collision damage caused by the guide sleeve due to the tilt.

[0077] Combination Fig. 9 It can be seen that the material-retrieving mechanism 40 is a truss-type material-retrieving manipulator, including a mounting unit, a bidirectional power mechanism, a slewing mechanism and a clamping mechanism 401. The mounting unit includes a supporting unit fixedly connected to the working platform 101 and a crossbeam 402a arranged on the supporting unit, the supporting unit includes a pair of vertically arranged supporting legs 402b, and the crossbeam 402a is horizontally arranged on the upper part of the two supporting legs 402b;

[0078] The bidirectional power mechanism includes a Y-direction moving mechanism disposed on the crossbeam 402a and a Z-direction moving mechanism driven by the Y-direction moving mechanism to move back and forth horizontally, and the Z-direction moving mechanism has a lifting frame 403a;

[0079] The slewing mechanism is arranged on the lifting frame 403a, and comprises a slewing power source, a slewing transmission assembly connected to the slewing power source, and a slewing frame 404a fixedly connected to the slewing transmission assembly;

[0080] The clamping mechanism 401 is arranged on the rotary frame 404a, and has an opening and closing structure driven by the second power mechanism, and two material-taking clamping members 401a are fixed on the opening and closing structure.

[0081] When working, the bidirectional power mechanism can meet the arbitrary adjustment of the clamping mechanism 401 in the horizontal and height directions, and meet the round-trip requirements of the clamping mechanism 401 between the material picking station and the loading station; the rotary power source can drive the rotary frame 404a to rotate through the rotary transmission assembly, thereby realizing the 90-degree flip of the clamping mechanism 401 described later, so that the clamping mechanism 401 has two working states, namely, horizontal state and vertical state. The guide sleeve is flipped 90 degrees and assembled on the piston rod of the hydraulic cylinder, and the structure is ingenious; the material picking clamp 401a can be opened freely, thereby meeting the clamping requirements of different guide sleeves.

[0082] Combination Fig. 9 It can be seen that the Y-axis moving mechanism includes a moving seat 403b and a first linear power mechanism that drives the moving seat 403b to move back and forth laterally on the beam 402a; to ensure the movement trajectory and accuracy of the moving seat 403b, the beam 402a is provided with a third guide rail 403c extending along its length direction, and the moving seat 403b is provided with a third slider clamped on the third guide rail 403c.

[0083] Combination Fig. 9 It can be seen that the first linear power mechanism includes a second motor 403d fixed on the moving seat 403b, a third gear mounted on the motor shaft of the second motor 403d, and a third rack 403e fixed on the beam 402a, and the third rack 403e is arranged along the length direction of the beam 402a and meshes with the third gear. When working, the second motor 403d drives the third gear to rotate, so that the third gear moves laterally along the third rack 403e on the beam 402a, and then drives the moving seat 403b to move back and forth laterally along the third guide rail 403c on the beam 402a, so as to meet the material taking needs of the clamping mechanism 401.

[0084] Combination Fig. 9 It can be seen that the Z-direction moving mechanism also includes a third power mechanism and a vertically arranged linear module 403f. The third power mechanism is transmission-connected to the linear module 403f. The lifting frame 403a is fixedly connected to the lifting block of the linear module 403f. The second power mechanism drives the lifting frame 403a to rise and fall through the linear module 403f to meet the reciprocating requirements of the clamping mechanism 401 in the Z direction.

[0085] In actual installation, the third power mechanism is preferably a compact synchronous belt transmission mechanism, that is, a synchronous belt transmission pair driven by the third motor 403g, which is connected to the screw in the linear module 403f. When working, the third motor 403g drives the transmission screw of the linear module 403f to rotate through the synchronous belt transmission pair, thereby realizing the up and down movement of the lifting frame 403a in the Z direction, so that the clamping mechanism 401 can be adjusted arbitrarily in the Z direction.

[0086] Combination Figure 10-11It can be seen that the rotary power source includes a first cylinder 404b, which is vertically arranged, and the lifting frame 403a has a horizontally arranged support 404c, and the first cylinder 404b is fixed on the support 404c; the rotary transmission assembly includes a first rack 404d that is lifted and lowered along the first guide rail on the lifting frame 403a (the first rack 404d has a first slider that cooperates with the first guide rail) and a first gear 404e that meshes with the first rack 404d, and the wheel axle of the first gear 404e is rotatably penetrated and arranged on a vertical plate of the lifting frame 403a, and the other end of the wheel axle is fixedly connected to the rotary frame 404a; the piston rod of the first cylinder 404b is connected to the first rack 404d, and when its piston rod is extended and retracted, it drives the first rack 404d to lift and lower along the first guide rail, thereby realizing the forward and reverse rotation of the first gear 404e to meet the flipping and resetting requirements of the clamping mechanism 401.

[0087] A spring buffer 404f is also fixedly connected to the first rack 404d, and the other end of the spring buffer 404f is passed through the support 404c of the first cylinder 404b, which has a buffering effect and effectively ensures the operating reliability of the rotary mechanism.

[0088] Combination Fig.11 It can be seen that the rotating frame 404a includes a base plate fixed on the rotating shaft and a pair of reinforcing plates fixed on the base plate. The opening and closing structure includes a fixing member (i.e., a fixing seat 401b fixed on the rotating frame 404a), and two reinforcing plates are fixedly connected to the back of the fixing seat 401b at intervals to realize the transmission connection between the fixing seat 401b and the first gear 404e.

[0089] like Figure 10-14 As shown, the opening and closing structure includes a second gear 401c rotatably arranged in the middle of the fixed seat 401b and a pair of second racks 401d meshing with the second gear 401c. The two second racks 401d are located on both sides of the second gear 401c and are arranged in parallel, so that the movement directions of the two second racks 401d are always opposite, thereby realizing the opening and closing of the two clamping members to meet the material taking requirements of the guide sleeve;

[0090] Combination Figure 10-12 It can be seen that the opening and closing structure also includes a pair of connecting parts (i.e. connecting plates 401e), each second rack 401d is fixedly connected to a connecting plate 401e, and each connecting plate 401e is fixedly connected to a material picking clamp 401a, thereby realizing the transmission connection between the material picking clamp 401a and the second rack 401d.

[0091] In order to ensure the movement trajectory of each material picking clamp 401a, a pair of second guide rails 401f arranged along the length direction of the fixed seat 401b are also provided, and each connecting plate 401e is provided with a pair of second sliders 401g matched with the second guide rails 401f, so as to ensure the stable operation of the material picking clamp 401a and improve the movement accuracy of the connecting plate 401e and the material picking clamp 401a;

[0092] Combination Fig.13 It can be seen that the second power mechanism includes a second cylinder 401i mounted on a fixed seat 401b through a bracket 401h, a cylinder body of the second cylinder 401i is fixed to one end of the fixed seat 401b, and a piston rod of the second cylinder 401i is fixed to the material-taking clamping member 401a at the other end of the fixed seat 401b. During operation, since the two second racks 401d are located on both sides of the second gear 401c and mesh with the second gear 401c, when the second cylinder 401i drives one of the second racks 401d to move linearly, the second rack 401d will inevitably drive the other second rack 401d to move linearly in the opposite direction through the second gear 401c, thereby realizing the opening and closing of the two material-taking clamping members 401a.

[0093] In actual installation, in order to ensure the normal operation of the rack, a gate-shaped limit frame 401j is fixed on the second gear 401c, and the ends of the two second racks 401d pass through the limit frame 401j. Fig.12 shown.

[0094] Combination Figure 12-14 It can be seen that the two material-retrieving clamping members 401a have the same structure, and the material-retrieving clamping member 401a includes a supporting block 401a1 and a clamping block 401a2 in an annular structure, and the upper surface of the supporting block 401a1 has a groove, and the clamping block 401a2 is fixed in the groove. The two clamping blocks 401a2 are arranged opposite to each other, and clamp guide sleeves of different sizes by opening and closing.

[0095] In order to avoid damaging the guide sleeve surface, Fig.14As shown, the clamping mechanism 401 also includes an adsorption structure, which includes a crossbar 401k mounted on a fixed seat 401b (the crossbar 401k is mounted on the fixed seat 401b through a pair of connecting blocks 401m) and an electromagnet 401n for adsorbing the top surface of the guide sleeve, the crossbar 401k passes through two support blocks 401a1, and the electromagnet 401n is fixed on the crossbar 401k located between the two support blocks 401a1 through an elastic buffer (preferably a compression spring). When working, the top surface of the guide sleeve is adsorbed by the electromagnet 401n, and the side ring surface of the guide sleeve is clamped by the clamping block 401a2, which can not only ensure the stable clamping of the guide sleeve, but also protect the surface of the guide sleeve from damage. In addition, when actually installed, the elastic buffer is preferably a compression spring to ensure that the end face of the electromagnet 401n floats and fits with the guide sleeve, further protecting the surface of the guide sleeve from damage.

[0096] The working principle and process of the clamping mechanism 401 of the present invention are as follows: the piston rod of the second cylinder 401i extends outward, so that the two material-picking clamping members 401a are in an open state; when the clamping mechanism 401 reaches the material-picking station, the electromagnet 401n is energized and magnetized, and then floats and absorbs the guide sleeve. Since there is a compression spring between the electromagnet 401n and the cross bar 401k, the floating adsorption of the guide sleeve is achieved, protecting the guide sleeve from damage; after the electromagnet 401n adsorbs the guide sleeve, the piston rod of the second cylinder 401i retracts, and the two second racks 401d both move toward the direction of the second gear 401c, so that the material-picking clamping members 401a are closed and the guide sleeve is clamped, and the clamping effect is good.

[0097] When it is necessary to flip, the piston rod of the first cylinder 404b extends downward, and the first rack 404d drives the first gear 404e to rotate clockwise, so that the rotating frame 404a and the fixed seat 401b rotate clockwise by 90 degrees, thereby turning the clamping mechanism 401 from a horizontal state to a vertical state, so as to facilitate the unloading and assembly of the guide sleeve; after the guide sleeve is unloaded, the piston rod of the first cylinder 404b retracts, and the first rack 404d drives the first gear 404e to rotate counterclockwise, so that the rotating frame 404a and the fixed seat 401b rotate counterclockwise by 90 degrees, and the clamping mechanism 401 is reset. The present invention fixes the clamping mechanism 401 on the rotating mechanism, realizes the flexible adjustment of the direction of the guide sleeve, and has an ingenious structure, which can not only realize the material taking of the guide sleeve, but also realize the rapid unloading of the guide sleeve.

[0098] The specific working process and principle of the multi-station storage system of the present invention are as follows:

[0099] The spacing of the movable rods 506 of each material storage rack 50 is adjusted according to the specifications of the guide sleeve to be assembled. When adjusting, the adjustment rod 503 is screwed to make the two adjustment seats 504 move back to back at the same time (of course, according to the actual situation, the adjustment rod 503 can also be screwed in the opposite direction to make the two adjustment seats 504 move towards each other) until the guide sleeve can enter the material storage slot and the movable rod 506 contacts the outer ring of the guide sleeve;

[0100] Each set of guide sleeves (multiple guide sleeves are stacked together) is sequentially loaded into the passing storage rack 50; the motor reducer 202 of the rotary conveying mechanism 20 drives the storage rack 50 equipped with the guide sleeves to move to the material taking station;

[0101] When the material storage rack 50 reaches the material taking station, the first motor 302 of the lifting loading mechanism 30 drives the lifting plate 304 to rise through the transmission screw, and the four material taking push rods 305 on the lifting plate 304 pass through the working platform 101 and the base 501 of the material storage rack 50 in turn upward and act on the four corners of the supporting plate 502. The material taking push rods 305 push the supporting plate 502 up smoothly, and the supporting plate 502 rises smoothly along the fixed rod 505 and the movable rod 506, thereby realizing the overall rise of the guide sleeve, so that the guide sleeve is sequentially removed from the top of the material storage tank;

[0102] During the lifting process, the bidirectional power mechanism adjusts the clamping mechanism 401 (the initial state is horizontal) to move to the top of the guide sleeve. After the clamping mechanism 401 is lowered to the position, the electromagnet 401n is energized to make it electromagnetic. The electromagnet 401n floats and absorbs the guide sleeve, and then the material-taking clamping member 401a clamps the guide sleeve to ensure the clamping effect of the guide sleeve.

[0103] After the guide sleeve of the material-retrieving station is taken away, the bidirectional power mechanism adjusts the height and horizontal position of the clamping mechanism 401 and the guide sleeve, and the first cylinder 404b of the rotary mechanism works to make the clamping mechanism 401 and the guide sleeve synchronously flip 90 degrees; the bidirectional power mechanism is used to adjust the height of the central axis of the guide sleeve to make it coaxial with the piston rod of the hydraulic cylinder, and finally the bidirectional power mechanism is used to adjust the horizontal position of the guide sleeve, and the guide sleeve is assembled onto the piston rod of the hydraulic cylinder, thereby realizing the automatic material retrieving and loading of the piston rod, and the structure is ingenious.
