Description

Technical Field

[0001] The present application relates to the technical field of stackers, and in particular to a guide wheel auxiliary mechanism for a stacker. Background Art

[0002] With the rapid development of the logistics industry, as the core equipment in the automated warehouse, the operating efficiency and stability of the stacker are crucial to the overall logistics operation. The stacker is mainly responsible for high-speed and accurate storage and retrieval operations between the shelves of the stereoscopic warehouse. In order to ensure the stable operation of the stacker on the shelf track, guide wheels are widely used at its bottom to play a supporting and guiding role. The design of the guide wheels must ensure that the stacker can move smoothly along the track during movement to reduce vibration and deviation.

[0003] Stackers in the prior art mostly use a single-track movement method. This design can easily cause the center of gravity to shift during the operation of the load bridge, especially when handling goods of different weights and sizes. Long-term center of gravity shift causes excessive friction between the guide wheel and the track on one side, which not only shortens the service life of the guide wheel, but also increases the risk of damage to the single-sided guide wheel. Once the guide wheel is damaged, the replacement process is often very complicated, so it needs to be improved. Utility Model Content

[0004] In order to solve the problem that the existing monorail movement method is easily damaged, the present application provides a stacker guide wheel auxiliary mechanism.

[0005] The stacker guide wheel auxiliary mechanism provided in this application adopts the following technical solution:

[0006] A stacker guide wheel auxiliary mechanism comprises two groups of guide mechanisms symmetrically arranged on both sides of a stacker bridge, each group of the guide mechanisms comprises a guide rail and two guide pulleys, the guide rails are vertically arranged along the height direction of the stacker, a connecting component for connection is provided on the guide rails, both sides of the guide rails in the width direction are provided with rail grooves, the two guide pulleys correspond to the two rail grooves respectively, the guide pulleys are slidably connected in the corresponding rail grooves, the two guide pulleys are jointly provided with a support for connecting to the stacker bridge, and a control component for controlling the contact tightness between the guide pulley and the guide rail is provided on the support.

[0007] Since most existing stackers use a single-track movement, this design can easily cause the center of gravity to shift during the operation of the load bridge, especially when handling goods of different weights and sizes. Long-term center of gravity shift causes excessive friction between the guide wheel and the track on one side, which not only shortens the service life of the guide wheel, but also increases the risk of damage to the single-sided guide wheel. Once the guide wheel is damaged, the replacement process is often very complicated. By adopting the above-mentioned technical solution, including two groups of guide mechanisms, each group of guide mechanisms includes a guide rail and two guide pulleys, the guide rails are installed on the stacker through a connecting component, and the two guide pulleys are slidably connected in the rail grooves of the guide rails. At the same time, the guide pulleys control the contact tightness between the guide rails and the guide rails through the control component. When the stacker is overloaded during operation, it means that its load is not evenly distributed on the guide pulleys on both sides. In this case, the guide pulley on the overloaded side The guide pulley will be subjected to greater extrusion pressure and produce greater friction with the guide rail. The control component works to actively apply pressure to the guide pulley on one side that has not been subjected to excessive extrusion pressure. This adjustment is intended to redistribute the load so that the guide pulleys on both sides are more evenly stressed. When the adjustment is completed, the force on the guide pulley that has previously been subjected to excessive extrusion pressure will be reduced accordingly, thereby reducing the friction between the guide pulley and the guide rail. The stability of the stacker during operation is improved through the settings of the two guide pulleys and the control component. Even when handling goods of different weights and sizes, the center of gravity offset can be effectively reduced, thereby ensuring the smooth operation of the stacker. At the same time, the guide wheels on both sides are more evenly stressed, reducing the friction between the guide wheels and the guide rails, extending the service life of the guide wheels, reducing the frequency of maintenance and replacement, and reducing the heat and wear generated by friction, thereby ensuring the working efficiency of the guide wheels.

[0008] Optionally, the control component includes a fixed seat, a control cylinder and a pulley seat, the fixed seat is connected to the support, the control cylinder is arranged on the fixed seat, the control cylinder is arranged toward the guide slide rail, the pulley seat is hinged at the output end of the control cylinder, and the guide pulley is rotatably connected to the pulley seat.

[0009] By adopting the above technical solution, the control component includes a fixed seat, a control cylinder and a pulley seat; when the stacker is overloaded during operation, the guide pulley on the overloaded side will be subjected to a greater extrusion pressure and produce a greater friction with the guide slide rail, and the control cylinder on the other side will work, and the control cylinder drives the pulley seat to move, actively applying pressure to the guide pulley on the other side, thereby reducing the force on the guide pulley that was previously subjected to excessive extrusion pressure; the setting of the fixed seat, the control cylinder and the pulley seat helps to achieve dynamic balance adjustment, and the contact force between the guide pulley and the guide slide rail can be adjusted to balance the pressure on both sides, reducing the problem of excessive extrusion pressure on one side of the guide pulley caused by overload, which accelerates the wear of the guide pulley, and extending the service life of the guide pulley and the guide slide rail.

[0010] Optionally, a stabilizing component for stabilizing the movement direction of the control cylinder is provided on the fixed seat, and the stabilizing component includes a fixed rail, a fixed slider and a sliding plate, the fixed rail is connected to the fixed seat, the fixed slider is slidably connected to the fixed rail, the sliding plate is connected to the top of the fixed slider, the output end of the control cylinder is hinged on the sliding plate, and the pulley seat is connected to the sliding plate.

[0011] By adopting the above technical solution, a stabilizing component is installed on a fixed seat, and the stabilizing component includes a fixed track, a fixed slider and a sliding plate; when the control cylinder is working, the control cylinder pushes the sliding plate, and the sliding plate slides on the fixed track through the fixed slider, and as the sliding plate moves, the guide pulley on the sliding seat is driven to change, thereby adjusting the contact tightness between the guide pulley and the guide slide rail to balance the pressure on both sides; by setting the fixed track, the fixed slider and the sliding plate, the movement direction of the control cylinder when pushing the sliding plate is ensured to be stable, thereby improving the working efficiency of the control cylinder and ensuring the accuracy and speed of the guide pulley adjustment.

[0012] Optionally, the sliding plate is provided with a fixing bolt for connecting with the fixed sliding block, and the fixing bolt passes through the sliding plate and is threadedly connected to the fixed sliding block.

[0013] By adopting the above technical solution, the sliding plate and the fixed slider are fixed by fixing bolts. The setting of the fixing bolts ensures that the connection between the sliding plate and the fixed slider is firm and reliable, reducing the risk of loosening or falling off between the sliding plate and the fixed slider. At the same time, disassembly and assembly are convenient, simplifying the installation process.

[0014] Optionally, a guide rod is provided on the sliding plate, a sliding sleeve is hingedly provided on the output end of the control cylinder, the sliding sleeve is slidably connected to the guide rod, and an elastic member for buffering is provided between the guide rod and the sliding sleeve.

[0015] By adopting the above technical solution, the guide rod is installed on the sliding plate, the sliding sleeve is slidably installed on the guide rod, and an elastic member is installed between the guide rod and the sliding sleeve; through the arrangement of the guide rod, the sliding sleeve and the elastic member, when the stacker is overloaded during operation, the control cylinder will perform corresponding telescopic movement according to the overload situation, and this movement is transmitted to the sliding sleeve through the hinge point. Since the elastic member is installed on the guide rod, the sliding sleeve drives the sliding plate to move, thereby adjusting the contact tightness between the guide pulley and the guide slide rail; in this process, the contact force between the guide pulley and the guide slide rail is too large. When the contact force is large, the compression deformation of the elastic part will absorb part of the force and reduce the contact force. When the contact force is too small, the tensile deformation of the elastic part will increase the contact force to ensure proper contact between the guide pulley and the guide rail. The stability under eccentric load conditions is improved by setting the guide rod, sliding sleeve and elastic part, which can respond quickly and accurately to ensure that the stacker can still operate stably under eccentric load conditions. At the same time, the size of the contact force can be dynamically adjusted through the compression and tensile deformation of the elastic part to prevent overload and wear caused by excessive contact force, and also avoid sliding and instability caused by too small contact force.

[0016] Optionally, a limiting collar for limiting the detachment of the sliding sleeve is provided at the end of the guide rod, and the limiting collar is connected to the outer wall of the guide rod.

[0017] By adopting the above technical solution, a limit collar is installed at the end of the guide rod; the setting of the limit collar ensures that the sliding sleeve will not detach from the guide rod due to unexpected circumstances when sliding along the guide rod, thereby reducing equipment failures or safety accidents caused by the sliding sleeve falling off and improving the stability of equipment operation.

[0018] Optionally, the connecting assembly includes a plurality of connecting plates and a plurality of fixing parts, the plurality of connecting plates are arranged in sequence along the length direction of the guide rail, the connecting plates are arranged vertically on the end walls of the guide rail, the plurality of fixing parts are connected to corresponding connecting plates, and each of the fixing parts is provided with a through hole for bolts to pass through.

[0019] By adopting the above technical solution, the connecting assembly includes a plurality of connecting plates and a plurality of fixing parts. The connecting plates are welded and fixed on the guide rails and fixed by the fixing parts. By setting the connecting plates and the fixing parts, the structural stability of the guide rails can be enhanced, and deformation and displacement can be better resisted, thereby ensuring the normal operation of the equipment. At the same time, it is easy to install and fix, simple to operate, and easy to adjust.

[0020] Optionally, two of the fixing members form a group, each group of the fixing members corresponds to a single connecting plate, and the two fixing members are symmetrically arranged on the corresponding connecting plates.

[0021] By adopting the above technical solution, two fixings are grouped together; the connection strength is improved by setting the layout of the fixings, and the symmetrical design enables the connecting plate to evenly disperse the force when subjected to force, further enhancing the stability of the overall structure and helping to reduce deformation and distortion caused by uneven force, thereby maintaining long-term stable operation of the equipment.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] The two guide pulleys and control components are used to improve the stability of the stacker during operation. Even when handling goods of different weights and sizes, the center of gravity deviation can be effectively reduced, thereby ensuring the smooth operation of the stacker. At the same time, the guide wheels on both sides are more evenly stressed, reducing the friction between the guide wheels and the guide rails, extending the service life of the guide wheels, reducing the maintenance and replacement frequency, and reducing the heat and wear caused by friction, thereby ensuring the working efficiency of the guide wheels.

[0024] The setting of the fixed seat, the control cylinder and the pulley seat is helpful to achieve dynamic balance adjustment. The contact force between the guide pulley and the guide rail can be adjusted to balance the pressure on both sides, reduce the problem of excessive extrusion pressure on one side of the guide pulley due to eccentric load, and accelerate the wear of the guide pulley, and extend the service life of the guide pulley and the guide rail;

[0025] By setting the guide rod, sliding sleeve and elastic parts, the stability under the condition of eccentric load is improved, and it can respond quickly and accurately to ensure that the stacker can still operate stably under the condition of eccentric load. At the same time, through the compression and tensile deformation of the elastic parts, the size of the contact force can be dynamically adjusted to prevent overload and wear caused by excessive contact force, and also avoid sliding and instability caused by too small contact force.

[0031] The present application embodiment discloses a stacker guide wheel auxiliary mechanism. Figure 1 The stacker guide wheel auxiliary mechanism includes two sets of guide mechanisms 1. In this embodiment, the two sets of guide mechanisms 1 are symmetrically installed on both sides of the stacker bridge. The guide mechanisms 1 are used for guiding when the stacker bridge is lifted or lowered.

The guide rail 2 is vertically installed along the height direction of the stacker frame. A connecting assembly 4 is installed on the guide rail 2. The connecting assembly 4 includes a plurality of connecting plates 41 and a plurality of fixing members 42. The plurality of connecting plates 41 are welded and fixed on the guide rail 2. The plurality of connecting plates 41 are installed in sequence and equidistantly along the length direction of the guide rail 2, and each connecting plate 41 is arranged vertically to the guide rail 2.

[0033] Reference Figure 1 and Figure 2 In this embodiment, the number of fixing members 42 is twice the number of connecting plates 41, and two fixing members 42 form a group. Each group of fixing members 42 corresponds to a single connecting plate 41. The fixing members 42 are pressed from steel. The two fixing members 42 in each group are symmetrically installed on the connecting plate 41, and each fixing member 42 is penetrated by a plurality of through holes 421, through which bolts can pass to realize the installation between the fixing members 42 and the stacking machine frame, so as to enhance the stability of the installation structure of the guide rail 2, better resist deformation and displacement, thereby ensuring the normal operation of the equipment, and at the same time facilitate installation and fixation, simple operation, and easy adjustment.

[0034] Reference Figure 1 and Figure 2The guide rail 2 is provided with rail grooves 21 on both sides along the width direction. The rail grooves 21 are provided along the length direction of the guide rail 2. The two rail grooves 21 correspond to the two guide pulleys 3 respectively. The guide pulleys 3 are slidably connected in the rail grooves 21. The two guide pulleys 3 are jointly installed with a support 5. In this embodiment, the support 5 is installed on the stacker bridge frame. A control component 6 is installed on the support 5. The control component 6 is used to control the contact tightness between the guide pulley 3 and the guide rail 2. The control component 6 is divided into two groups, and the two groups of control components 6 correspond to the two guide pulleys 3 respectively.

[0035] Reference Figure 3 Each control component 6 includes a fixed seat 61, a control cylinder 62 and a pulley seat 63. The fixed seat 61 is fixed on the support 5, and the control cylinder 62 is installed on the fixed seat 61. The control cylinder 62 is installed toward the guide rail 2. A stabilizing component 7 is installed between the control cylinder 62 and the pulley seat 63. The guide pulley 3 is rotatably installed on the pulley seat 63. In this embodiment, the control cylinder 62 can be finally controlled by sensor induction.

[0036] Reference Figure 3 The stabilizing assembly 7 includes a fixed rail 71, a fixed slider 72 and a sliding plate 73. The fixed rail 71 is installed on the fixed seat 61. The fixed rail 71 is arranged along the running direction of the control cylinder 62. The fixed slider 72 is slidably connected to the fixed rail 71. The sliding plate 73 is installed on the top of the fixed slider 72. A fixing bolt 8 is installed on the sliding plate 73. The fixing bolt 8 passes through the sliding plate 73 and is threadedly connected to the fixed slider 72 to achieve the fixation of the sliding plate 73 and the fixed slider 72. In this embodiment, the pulley seat 63 is installed and fixed to the end of the sliding plate 73.

[0037] Reference Figure 3 A guide rod 9 is fixedly mounted on the sliding plate 73, and the guide rod 9 is arranged in the same direction as the fixed rail 71. A sliding sleeve plate 10 is hingedly mounted on the output end of the control cylinder 62, and the sliding sleeve plate 10 is slidably connected to the guide rod 9, and an elastic member 11 is installed between the guide rod 9 and the sliding sleeve plate 10. The elastic member 11 can be a spring, and the spring has a corresponding damper. In this embodiment, the number of guide rods 9 on the sliding plate 73 can be two groups, so as to be able to respond quickly and accurately to ensure that the stacker can still operate stably under eccentric load conditions. At the same time, through the compression and tension deformation of the elastic member 11, the size of the contact force can be dynamically adjusted to prevent overload and wear caused by excessive contact force, and also avoid sliding and instability caused by too small contact force.

[0038] Reference Figure 3A limit collar 91 is fixedly installed at the end of each guide rod 9. The limit collar 91 is installed at the end of the guide rod 9 close to the control cylinder 62 to ensure that the sliding sleeve 10 will not fall off the guide rod 9 due to unexpected circumstances when sliding along the guide rod 9, thereby reducing equipment failures or safety accidents caused by the falling off of the sliding sleeve 10 and improving the stability of equipment operation.

[0039] The implementation principle of a stacker guide wheel auxiliary mechanism in an embodiment of the present application is as follows: when the stacker is unbalancedly loaded during operation, it means that its load is not evenly distributed on the guide pulleys 3 on both sides. In this case, the guide pulley 3 on the unbalanced side will be subjected to a greater extrusion force and produce a greater friction with the guide rail 2. The control cylinder 62 will perform corresponding telescopic movement according to the unbalanced load situation. This movement is transmitted to the sliding sleeve 10 through the hinge point. Since the elastic member 11 is installed on the guide rod 9, the sliding sleeve 10 drives the sliding plate 73 to move, thereby adjusting the contact tightness between the guide pulley 3 on the other side and the guide rail 2, and actively applying pressure to the guide pulley 3 on the other side that is not subjected to excessive extrusion force. This adjustment purpose The load is redistributed so that the force on the guide pulleys 3 on both sides is more evenly distributed. After the adjustment is completed, the force on the guide pulley 3 that has previously been subjected to too much extrusion force will be reduced accordingly, thereby reducing the friction between the guide pulley 3 and the guide rail 2. The stability of the stacker during operation is improved by means of the two guide pulleys 3 and the control component 6. Even when handling goods of different weights and sizes, the center of gravity deviation can be effectively reduced, thereby ensuring the smooth operation of the stacker. At the same time, the force on the guide wheels on both sides is more evenly distributed, reducing the friction between the guide wheels and the guide rail 2, extending the service life of the guide wheels, reducing the maintenance and replacement frequency, and reducing the heat and wear generated by friction, thereby ensuring the working efficiency of the guide wheels.

[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
