Description

Technical Field

[0001] The present invention relates to a warehouse transfer device, in particular to a high-speed stacker crane. Background Art

[0002] In an automated stereoscopic warehouse, a stacker crane is essential. The automated stereoscopic warehouse can be several floors high, more than a dozen floors high, or even dozens of floors high. The function of the stacker crane is to carry a fork on a liftable load platform and send the goods to a designated position through the telescopic movement of the fork.

[0003] However, in order to send materials into different goods shelves or warehouses, an ordinary stacker crane needs to move, so it has a traveling mechanism (such as the patent name: a clamping fork for a stacker crane and its stacker crane, application number 202123016342.7). However, this traveling mechanism includes a traveling wheel set, a traveling motor, and a guide wheel set. The traveling wheel set includes four traveling wheels, and the four traveling wheels are respectively arranged on the left and right sides of the main body vertical frame and are clamped on the lower guide rail. The traveling motor is arranged on the right side of the bottom of the main body vertical frame and is fixedly connected to the right traveling wheel, and the traveling wheel moves along the lower guide rail. The guide wheel set includes four guide wheels, and the four guide wheels are respectively arranged on the left and right sides of the top of the main body vertical frame, and the four guide wheels are clamped on the upper guide rail. Start the traveling motor to drive the traveling wheels to rotate, and then drive the main body vertical frame to move along the upper guide rail and the lower guide rail.

[0004] However, when the traveling motor directly drives the traveling wheels to move along the lower guide rail, the traveling wheels are prone to slipping when the vertical frame runs too fast. Therefore, the running speed of the vertical frame with the above structure is not fast, which reduces the overall working efficiency. Summary of the Invention

[0005] In order to overcome the deficiencies of the prior art, the present invention provides a high-speed stacker crane.

[0041] As can be fully understood by those skilled in the art, the features of different embodiments of the present disclosure can be partially or fully coupled or combined with each other, and can cooperate with each other in various ways and be technically driven. The embodiments of the present disclosure can be executed independently of each other, or can be executed together in a mutually dependent relationship.

[0042] Referring to Figures 1 to 4 and Figure 15 and Figure 16 , the present invention discloses a high-speed stacker, which includes a vertical frame 100. A loading platform 101 is provided on the vertical frame 100. The vertical frame 100 is a square frame body. The loading platform 101 is located in the vertical frame 100. A hoist 102 is installed on one side of the vertical frame 100. The hoist 102 is connected to the loading platform 101 through a steel cable to drive the loading platform 101 to lift and lower. A telescopic fork is provided on the loading platform 101. Figure 1 and Figure 2 There is also a wire car 120 on the telescopic fork of

[0043] As shown in the figure, a rack 104 is arranged along the length direction of the guide rail 103. A traveling motor 105 and a driving gear 106 fixedly connected to the traveling motor 105 are provided on the vertical frame 100. The driving gear 106 meshes with the rack 104. Therefore, when the traveling motor 105 drives the driving gear 106 to rotate, but the rack 104 is fixed, so when the driving gear 106 rotates, it will push the vertical frame 100 to move, so that the vertical frame 100 can move to the position corresponding to the goods shelf or the corresponding warehouse loading port. The rack 104 can be fixed on the guide rail 103 or fixed separately. As a preferred structure of the present application, it further includes a base plate 107 and a side support plate 108 vertically arranged on the base plate 107. The rack 104 is fixed to the side support plate 108 by screws. The base plate 107 is fixed to the ground by fixing. The installation space for fixing the rack 104 on the track is too small, so the rack 104 is fixed separately through the side support plate 108.

[0044] As shown in the figure, there are two traveling motors 105, which are respectively located on both sides of the vertical frame 100. The two traveling motors 105 are started at the same time. Therefore, the driving gears 106 mesh with the rack 104 at the same time and push the vertical frame 100 to move at the same time. Because the vertical frame 100 is more than twenty meters high and is very heavy, the load on the traveling motor 105 is also large and it needs to be used for a long time. Therefore, the above structure not only increases the reliability of the equipment, but also the load on each driving gear 106 is smaller, thus extending the service life of the driving gear 106 and the rack 104.

[0045] The traveling motor 105 is vertically arranged and the motor shaft of the traveling motor 105 is vertically downward. The driving gear 106 is fixed to the motor shaft, and the rack 104 is vertically arranged. The driving gear 106 is parallel to the ground and just meshes with the rack 104, which is convenient for the installation of the traveling motor 105 and reduces the space of the equipment.

[0046] As shown in the figure, the rolling support mechanism includes two traveling wheels 109. The traveling wheels 109 are in contact with and roll on the track surface of the guide rail 103. Opposite rotating shafts 110 are provided on the traveling wheels 109. The rotating shafts 110 are arranged on the vertical frame 100 through bearings 111. The traveling wheels 109 are used as supports alone, which not only has a simple structure, but also does not affect the movement of the vertical frame 100 even if it slips.

[0047] As a further structure, it further includes a wheel seat 112. A wheel groove is provided inside the wheel seat 112. The wheel seat 112 is a square box body. The wheel groove is the inner cavity of the wheel groove. The opening at the bottom of the box body is the notch of the wheel groove. The rotating shaft 110 is arranged on the groove wall of the wheel groove through a bearing. Thus, the traveling wheel 109 is located inside the wheel groove and only partially exposes from the notch to contact the guide rail 103. The above structure is convenient for manufacturing and assembly. Moreover, a positioning strip 113 is provided on the wheel seat 112, and a positioning groove 114 matching with the positioning strip 113 is provided on the end face at the bottom of the vertical frame 100. The precision of the positioning strip 113 and the positioning groove 114 is convenient for machining, and the precision can be very high. Therefore, the perpendicularity of the wheel seat 112 relative to the guide rail 103 can be ensured through the cooperation of the positioning strip 113 and the positioning groove 114, thereby ensuring the perpendicularity of the traveling wheel 109 relative to the guide rail 103, preventing the traveling wheel 109 from skewing and generating eccentric wear, and extending the service life.

[0048] As shown in the figure, an optical distance measuring sensor 115 capable of detecting the moving distance of the vertical frame 100 is provided on the vertical frame 100, and there is a reflector 116 on the guide rail 103. Therefore, the moving distance of the vertical frame 100 can be measured by the optical distance measuring sensor 115, and a travel switch 117 for sensing the limit stroke of the vertical frame 100. When the travel switch 117 collides with the limit plate on the guide rail 103, it means that the vertical frame 100 has moved to the limit position and needs to stop. Moreover, there is also a buffer oil cylinder 118 on the guide rail 103. When the vertical frame 100 approaches the limit position, the speed will be buffered by the buffer oil cylinder 118, ensuring safety. Among the above, the optical distance measuring sensor 115, the travel switch 117 and the buffer oil cylinder are all existing devices, so the specific structures and principles will not be described in detail.

[0049] As Figure 5 shown, the telescopic fork includes a fork seat 1, a lifting frame 2 and forks 3 arranged on the lifting frame 2. Of course, there are two forks 3 arranged parallel to each other. A lifting drive mechanism is provided on the fork seat 1. The lifting drive mechanism is connected to the lifting frame 2 and can drive the lifting frame 2 to lift and lower. A telescopic drive mechanism is provided on the lifting frame 2. The telescopic drive mechanism is connected to the forks 3 and can drive the forks 3 to telescope, thereby improving the transfer speed and also improving the overall working efficiency of the stacker.

[0050] The fork 3 of the present application is used to transport the silk cart to the corresponding workshop or warehouse on the upper floor. To prevent the silk cart from moving during transportation or lifting, there is a positioning rod 4 on the fork 3, and there are positioning holes on the silk cart. Therefore, when the fork 3 lifts the silk cart, the positioning rod 4 is inserted into the positioning hole. Therefore, when initially lifting the silk cart, the fork 3 needs to rise to insert the positioning rod 4 into the positioning hole. After transporting the silk cart to the destination position, the fork 3 needs to descend to remove the positioning rod 4 from the positioning hole. Only in this way can the fork 3 retract and start to fork the next silk cart. Therefore, the present application designs a telescopic and liftable electric fork 3 for the above application environment, and realizes the lifting and telescoping of the fork 3 through a lifting drive mechanism and a telescoping drive mechanism.

[0051] As Figure 6 , Figure 12 and Figure 13 shown, as a specific structure, the lifting drive mechanism includes a lifting drive motor 5 arranged on the fork seat 1, two eccentric connectors 6, two lifting shafts 7, and a lifting transmission mechanism. The lifting shafts 7 are all slidably connected to the lifting frame 2 through bearings. The shaft heads of the lifting shafts 7 are fixedly connected to the upper parts of the corresponding eccentric connectors 6. The lifting drive motor 5 is fixedly connected to the lower parts of the eccentric connectors 6 through the lifting transmission mechanism. In this embodiment, when the lifting drive motor 5 works, it drives the two eccentric connectors 6 to rotate simultaneously through the lifting transmission mechanism. When the eccentric connectors 6 rotate, they drive the corresponding lifting shafts 7 to rotate eccentrically. Since the lifting shafts 7 are all slidably connected to the lifting frame 2 through bearings, the lifting frame 2 will maintain a horizontal state and will not rotate with the lifting shafts 7, but only move linearly up and down, thereby realizing the linear lifting of the fork 3.

[0052] A square hollow frame body is provided on the bottom surface of the lifting frame 2. The sliding groove 8 is located on the inner surface of the hollow frame body. The end parts of the lifting shafts 7 are located in the hollow box body. The bearings 9 on the lifting shafts 7 can roll in the sliding groove 8. Therefore, the friction between the bearings 9 and the sliding groove 8 is very small. And the weight of the lifting frame 2 is very large. Therefore, when the bearings 9 roll, they will not drive the lifting frame 2 to translate through the frictional force, ensuring that when the lifting shafts 7 rotate, the lifting frame 2 will not rotate with the lifting shafts 7 but only move linearly up and down. The positioning of the bearings 9 on the lifting shafts 7 is realized through two hoop fasteners, one hoop fastener on each side of the bearings 9, so as to limit the movement of the bearings 9 along the lifting shafts 7.

[0053] As shown in the figure, as a specific structure, the lifting transmission mechanism in this structure includes a lifting shaft group and a lifting gear group. The lifting shaft group includes a lifting power shaft 10 arranged in the fork seat 1, relatively arranged lifting eccentric shafts 11, and several lifting tooth shafts. The lifting gear group includes several mutually meshing lifting transmission gears 13. The lifting power shaft 10, the lifting eccentric shafts 11, and several lifting tooth shafts are fixed to the corresponding lifting transmission gears 13, and the lifting power shaft 10, the lifting eccentric shafts 11, and several lifting tooth shafts are all connected to the fork seat 1 through bearings. The lifting drive motor 5 is connected to the lifting power shaft 10. The lifting eccentric shaft 11 is fixedly connected to the lower part of the eccentric connecting piece 6. The lifting drive motor 5 can be fixedly connected to the lifting power shaft 10 through a coupling piece, so as to drive the lifting power shaft 10 to rotate, thereby driving the lifting transmission gear 13 on the lifting power shaft 10 to rotate. The lifting transmission gear 13 on the lifting power shaft 10 drives the lifting transmission gears 13 on both sides to perform one-time transmission, so as to make the outermost lifting eccentric shaft 11 rotate, thereby driving the eccentric connecting piece 6 to rotate. The above structure has good reliability and can transmit a large torque. The eccentric connecting piece 6 includes an upper plate and a lower plate, has a lower hole and an upper hole, and the upper hole is formed by locking the upper plate and the lower plate with screws. The lifting shaft 7 is fixed in the upper hole, and the lifting eccentric shaft 11 is fixed in the lower hole. The fixing methods of the lifting shaft 7 and the lifting eccentric shaft 11 to the eccentric connecting piece 6 are conventional methods, so they will not be described in detail.

[0054] As shown in the figure, as a further preferred structure, the lifting transmission mechanism further includes a lifting transmission shaft 14. There are two groups of the lifting shaft group and the lifting gear group, and one group of the lifting shaft group corresponds to one group of the lifting gear group. The end of the lifting transmission shaft 14 is connected to the corresponding lifting power shaft 10. Through the above structure, power is driven at both ends of the lifting shaft 7 to drive its rotation, so as to avoid excessive unilateral force and rapid wear, thereby reducing its service life.

[0055] As Figures 7 to 11 shown, the telescopic drive mechanism includes a telescopic drive motor 15 arranged on the lifting frame 2, a telescopic transmission structure one, and a telescopic support and guiding structure one. The forklift fork 3 makes a linear movement on the lifting frame 2 through the telescopic support and guiding structure one. The telescopic drive motor 15 drives the forklift fork 3 to telescope through the telescopic transmission structure one. The telescopic drive motor 15 is fixed on the lifting frame.

[0056] The specific structure is as follows: The first telescopic drive structure includes a telescopic main shaft 16, a first telescopic gear shaft 17, a telescopic rack 18, a telescopic main gear 19, a telescopic driven gear 20 meshing with the telescopic main gear 19, a number of first telescopic driving gears 21, and a number of first telescopic intermediate gears 22. One end of the telescopic main shaft 16 is fixedly connected to the corresponding first telescopic driving gear 21, and the other end is fixedly connected to the telescopic driven gear 20. Some of the first telescopic gear shafts 17 are fixedly connected to the corresponding first telescopic driving gears 21, and some of the first telescopic gear shafts 17 are fixedly connected to the corresponding first telescopic intermediate gears 22. The telescopic drive motor 15 is fixedly connected to the telescopic main gear 19. The first telescopic driving gear 21 meshes with the corresponding first telescopic intermediate gear 22, and the telescopic rack 18 meshes with the first telescopic driving gear 21. The telescopic main shaft 16 and the first telescopic gear shaft 17 are both arranged on the lifting frame 2 through bearings.

[0057] The brief description of its working principle: The telescopic drive motor 15 drives the telescopic main gear 19 to rotate. The telescopic main gear 19 drives the telescopic driven gear 20 to rotate, and the telescopic driven gear 20 drives the telescopic main shaft 16 to rotate. The telescopic main shaft 16 drives the corresponding first telescopic driving gear 21 to rotate, and the first telescopic driving gear 21 drives the adjacent first telescopic intermediate gear 22 to rotate. The first telescopic intermediate gear 22 drives the adjacent first telescopic driving gear 21 to rotate simultaneously, so as to realize the rotation of all the first telescopic driving gears 21 and the first telescopic intermediate gears 22. At the same time, the telescopic rack 18 is fixed, so the first telescopic driving gear 21 drives the telescopic rack 18 to move along the telescopic rack 18 under the cooperation of the telescopic rack 18. The telescopic rack 18 is fixed to the forklift fork 3, so the forklift fork 3 moves with the telescopic rack 18 to realize telescoping. In the above structure, three first telescopic driving gears 21 and two first telescopic intermediate gears 22 are meshed with each other to realize the simultaneous meshing and transmission of multiple first telescopic driving gears 21 and the telescopic rack 18, which can greatly reduce the force received when a single gear meshes with the rack 104, thereby extending the service life of the gear.

[0058] As shown in the figure, a fork plate 23 is provided on the forklift fork 3. The fork plate 23 moves under the guidance of the second telescopic support and guiding structure and is driven by the second telescopic drive structure. The second telescopic drive structure includes a second telescopic gear shaft 24, an upper rack 10425, a lower rack 10426, a number of second telescopic driving gears 27, and a number of second telescopic intermediate gears 28. The fork plate 23 is fixed to the upper rack 10425, and the lower rack 10426 is fixed to the lifting frame 2. The second telescopic driving gear 27 meshes with the corresponding second telescopic intermediate gear 28, and the second telescopic driving gear 27 meshes with both the upper rack 10425 and the lower rack 10426. Some of the second telescopic gear shafts 24 are fixed to the second telescopic driving gears 27, and some of the second telescopic gear shafts 24 are fixed to the second telescopic intermediate gears 28.

[0059] When in use, the fork 3 and the fork plate 23 can move simultaneously. Therefore, the moving distance of the object on the fork plate 23 is the sum of the moving distances of the fork 3 and the fork plate 23, so it will not affect the stroke of the fork 3. However, when the device is not in use, the space occupied by the fork 3 is smaller, and the fork plate 23 can overlap with the fork 3, and the fork plate 23 does not need to be additionally installed with power. The specific working principle is as follows. When the fork 3 moves, it will drive the telescopic driving gear two 27 installed in the fork 3 and several telescopic intermediate gears two 28 to move with the fork 3. The design principles of the telescopic driving gear two 27 and several telescopic intermediate gears two 28 are the same as before, so they will not be elaborated here. The telescopic driving gear two 27 meshes with the upper rack 25 and the lower rack 26 at the same time. Since the lower rack 26 is fixed on the lifting frame 2 and does not move, the telescopic driving gear two 27 will rotate as the fork 3 moves. Therefore, when rotating, it will drive the upper rack 25 to move, and the upper rack 25 will drive the fork plate 23 to move, so that when the fork 3 moves, the fork plate 23 also moves relative to the fork 3.

[0060] The telescopic support and guiding structure one includes a support wheel one 29 oppositely arranged on the lifting frame 2 and a guiding wheel one 30 oppositely arranged on the lifting frame 2. The support wheel one 29 contacts the bottom surface of the fork 3 to support the fork 3, and the side surface of the fork 3 contacts the corresponding guiding wheel one 30 to limit its deflection during movement.

[0061] The telescopic support and guiding structure two includes a support wheel two 31 oppositely arranged on the fork plate 23 and a guiding plate 32 arranged on the fork plate 23. A guiding groove 33 is provided on the fork 3, the guiding plate 32 is located in the guiding groove 33, and the upper rack 25 is fixed to the bottom surface of the guiding plate 32.

[0062] The lifting frame 2 of the present application is square. Oppositely arranged square telescopic grooves 34 are provided on the lifting frame 2. The telescopic groove 34 is surrounded by three square plates. The fork 3 is located in the corresponding telescopic groove 34, and the support wheel one 29 is located on the groove wall of the telescopic groove 34. The support wheel one 29 can adopt a common needle roller bearing. Fork grooves one are provided on both sides of the fork 3, and the support wheel one 29 is located in the fork groove one. In this way, the fork groove one forms a guide rail groove, and the guiding wheel one 30 is oppositely arranged on the groove wall of the telescopic groove 34 and abuts against the part of the fork 3 exposed from the telescopic groove 34, so as to prevent the fork 3 from swaying during movement. The guiding wheel one 30 is also a bearing, so the specific installation structure will not be elaborated here.

[0063] Side plates 35 are oppositely provided below the fork plate 23. The guiding plate 32 is in the middle of the two side plates 35. The support wheel two 31 is arranged on the inner side of the side plates 35. Fork grooves two are provided on the outer side wall of the part of the fork 3 exposed from the telescopic groove 34, and the support wheel two 31 is located in the fork groove two. In this way, the fork groove two forms a guide rail groove.

[0064] The fork seat 1 is provided with a first sensor 36 for detecting the lifting of the fork 3 and a second sensor 37 for detecting the telescoping of the fork 3. Both the first sensor 36 and the second sensor 37 are optical sensors. The first sensor 36 can sense the lifting height of the fork 3, and the second sensor 37 can sense the extension and retraction of the fork 3.

[0065] The above has introduced in detail a high-speed stacker provided by an embodiment of the present invention. Specific examples are used in this article to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention; at the same time, for those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present invention.
