Description

Technical Field

[0001] This invention relates to the field of loading mechanisms, specifically to a mobile switching type accumulation and loading mechanism. Background Technology

[0002] In the fields of automated logistics sorting and industrial production conveying, with the diversification of goods and the increasing complexity of production line layouts, simple linear or fixed-direction conveying can no longer meet the demands. Loading devices are a crucial structure in the conveying field. Existing technologies generally employ a backward loading method. For example, the prior art, with publication number CN119796894B and titled "An Efficient Material Removal and Loading System and Its Control Method," aligns the flatbed truck with the conveying direction of the loading system, and then the loading system delivers the goods onto the flatbed truck. During the operation of the loading system, additional tasks such as shaping and reorienting the goods are required.

[0003] The loading mechanism needs to be aligned with the external conveyor belt to receive goods. For powdery or liquid materials, trace amounts of components leaked during transport can adhere to the surface of the loading mechanism, causing a decrease in the friction coefficient of the rollers and uneven distribution. When the pallet enters the loading mechanism, it is not only subjected to impact, but also experiences lateral traction deviation due to the lubrication effect of the adhered substances. This causes the goods to deflect upon reaching the feed end of the loading mechanism, ultimately resulting in goods accumulating on the loading mechanism with varying postures. Existing technologies require additional goods shaping mechanisms to address this posture, which is difficult to implement in situations with limited space.

[0004] The purpose of this invention is to design a mobile switching accumulation and loading mechanism to address the problems existing in the prior art. Summary of the Invention

[0005] In view of the problems existing in the prior art, the present invention provides a mobile switching accumulation and loading mechanism that can effectively solve at least one of the problems existing in the prior art.

[0006] The technical solution of this invention is: A mobile switching accumulation and loading mechanism includes: frame; A longitudinal conveying mechanism is provided, wherein the conveying direction of the longitudinal conveying mechanism is set along the length direction of the frame, and the longitudinal conveying mechanism is composed of several roller conveyor belts, with the bottom of several roller conveyor belts near the feed end of the frame fixedly connected to form a movable adjustment seat; A transverse conveying mechanism, wherein the conveying direction of the transverse conveying mechanism is set along the width direction of the frame, the transverse conveying mechanism is composed of several roller conveyor chains arranged at intervals, the transverse conveying mechanism and the longitudinal conveying mechanism are arranged alternately and a gap is left between the transverse conveying mechanism and the longitudinal conveying mechanism; There are several lifting mechanisms, each of which is connected to a corresponding roller conveyor belt so that it is higher or lower than the transverse conveyor mechanism; The feeding adaptive system includes an external torque detection device and an internal torque detection device disposed on the movable steering seat. The external torque detection device is used to detect the equivalent friction coefficient at both sides and the middle position of the discharge end of the connected external conveying mechanism when unloaded. The internal torque detection device is used to detect the equivalent friction coefficient at both sides and the middle position of the feeding end of the movable steering seat when unloaded. The movable steering seat is provided with a plurality of friction force adjustment mechanisms. The friction force adjustment mechanisms are used to adjust the surface friction coefficient at both sides and the middle position of the feeding end of the movable steering seat. Before the goods enter the movable steering seat, the control system adjusts the friction force adjustment mechanisms according to the equivalent friction coefficient deviation detected by the external torque detection device, so that the equivalent friction coefficient deviation at the feeding end of the movable steering seat is consistent with the equivalent friction coefficient deviation at the discharge end of the external conveying mechanism. The equivalent friction coefficient deviation represents the difference in the equivalent friction coefficients experienced by the left and right sides of the pallet. A rotating bearing is provided, which is located near the feed end of the frame. The fixed end of the rotating bearing is connected to the frame, and the rotating end of the rotating bearing is connected to the bottom of the movable adjustment seat through the lifting mechanism. Several ejection mechanisms are sequentially arranged on the side of the frame and can be ejected in the width direction of the frame. When the goods pass through the movable adjustment seat, the corresponding ejection mechanism extends and presses against the side wall of the pallet, thereby causing the pallet and the movable adjustment seat to rotate to the correction position. An angle locking device is installed at the position of the transverse conveying mechanism corresponding to the movable adjusting seat. When the movable adjusting seat is raised by the lifting mechanism, the angle locking device fixes the angle of the movable adjusting seat after a certain period of time. When the lifting mechanism drives the movable adjusting seat to descend, the angle locking device allows the movable adjusting seat to rotate in the unlocked state. A rotary mechanism is used to rotate the movable steering seat to its initial position after the movable steering seat is lowered by the lifting mechanism.

[0007] Furthermore, the rotary mechanism includes a first inclined surface and a second inclined surface. The first inclined surface is disposed at the bottom ends of both sides of the movable steering seat, and the second inclined surface is disposed on the transverse conveying mechanism and below the movable steering seat. When the conveying direction of the movable steering seat is along the length direction of the frame, the first inclined surface and the second inclined surface are disposed opposite each other in the vertical direction.

[0008] Furthermore, the angle locking device includes a hydraulic damper. The second inclined surface is provided with several notches. The hydraulic damper is provided on the side of the roller conveyor chain below the notches. The movable end of the hydraulic damper is connected to a locking block through a universal bearing. The locking block is provided with an electromagnetic mechanism. The first inclined surface is made of metal. After the lifting mechanism drives the movable steering seat to rise, the hydraulic damper drives the locking block to rise slowly, making the angle between the movable steering seat and the rotating bearing adjustable. After the hydraulic damper drives the locking block to rise to the upper limit, the electromagnetic mechanism is energized, causing the locking block to adhere to the first inclined surface, thereby locking the angle between the movable steering seat and the rotating bearing. The cross-section of the movable steering seat narrows after passing through the first inclined surface. The frame is equipped with a distance sensor. The sensing direction of the distance sensor is aligned with the position of the first inclined surface when the movable steering seat and the transverse conveying mechanism are at the same height. After the distance sensor detects that the movable steering seat is moving from bottom to top, the control system drives the electromagnetic mechanism to be energized. After the control system detects that the movable steering seat is moving from top to bottom, the control system drives the electromagnetic mechanism to be de-energized.

[0009] Furthermore, it includes a lateral drive component, the frame is provided with a plurality of grooves along its width direction, the roller conveyor chain is disposed in the grooves, and the lateral drive component drives the ejection mechanism and the lateral conveying mechanism to extend synchronously toward the width direction of the frame.

[0010] Furthermore, the ejection mechanism is disposed on the upper side of the frame corresponding to the transverse conveying mechanism. The ejection mechanism includes a plurality of first drive cylinders, which together drive a transverse push plate. The surface of the transverse push plate is provided with a wear-resistant plate.

[0011] Furthermore, the gap between the transverse conveying mechanism and the longitudinal conveying mechanism limits the maximum rotation angle of the movable steering seat to 5°.

[0012] Furthermore, the external torque detection device or the internal torque detection device includes a plurality of third drive cylinders, and each third drive cylinder has a torque sensor connected to its telescopic end. After being lifted by the third drive cylinder, the torque sensor abuts against the discharge end of the corresponding external conveying mechanism or the feed end of the movable steering seat. The telescopic end of the third drive cylinder is provided with a pressure sensor. The control system calculates the equivalent friction coefficient based on the signals from the torque sensor and the pressure sensor.

[0013] Furthermore, the outermost roller of the movable adjusting seat is a friction adjusting roller. The interior of the friction adjusting roller is a hollow structure with an embedded elastic element. The surface of the friction adjusting roller is provided with several mounting grooves along its axial direction that connect to the hollow structure. Several friction rings are equally spaced on the surface of the friction adjusting roller. The inner ring of the friction ring passes through the mounting groove and is connected to the elastic element. The friction adjusting roller is provided with sliding bearings that can move left and right on both sides and in the middle. One end of the elastic element is connected to the end of the friction adjusting roller, and the other end of the elastic element is connected to the inner ring of the sliding bearing. The movable adjusting seat is equipped with a horizontally arranged fourth drive cylinder, which is used to drive the sliding bearing, thereby driving the elastic element to move the friction ring closer or apart.

[0014] Furthermore, it includes several connecting plates, which are sequentially hinged to the side of the frame where the ejection mechanism is not provided. The connecting plates are driven by a second drive cylinder to swing up and down to dock with the corresponding truck.

[0015] Furthermore, a walking track is provided on the ground, and a walking mechanism that travels on the walking track is provided at the bottom of the frame. Several loading stations are arranged side by side on the side of the frame.

[0016] Therefore, the present invention provides the following effects and / or advantages: This application utilizes a feeding adaptive system in conjunction with a movable directional seat that can rotate after being raised. By balancing the equivalent friction coefficient deviation between the external conveying mechanism and the movable directional seat within a small angle range, the frictional force deviation between the two is brought close before receiving goods. This prevents the pallet at the bottom of the goods from experiencing a sudden change in friction force that could cause polarity deflection, ensuring that the goods are in a good initial posture upon entry. Furthermore, the movable directional seat and the ejection mechanism fine-tune the posture of the goods to achieve a straightening effect.

[0017] This application forms a movable steering seat by fixing the bottom of the longitudinal roller conveyor line near the feed end, and setting a powerless slewing bearing at the bottom, allowing the movable steering seat to rotate freely around the vertical axis. When goods with pallets are conveyed to the movable steering seat, the push-out mechanism presses against the pallet sidewall, pushing the movable steering seat and the goods together to rotate to the correction position. The posture correction can be completed using the existing power of the push-out mechanism.

[0018] This application incorporates a hydraulic damper on the transverse conveying mechanism, which extends slowly at a preset speed after the movable steering seat is raised. Before the damper is fully extended, the movable steering seat is in a freely rotatable state, providing ample time for cargo posture correction and ensuring correction accuracy. After locking, the angle of the movable steering seat is fixed, preventing angle deviation from occurring again during cargo lowering.

[0019] Other features and advantages of the invention will be set forth in the following description, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the invention are realized and obtained through the structures particularly pointed out in the description and the drawings.

[0031] To facilitate understanding by those skilled in the art, the structure of the present invention will now be described in further detail with reference to the accompanying drawings: refer to Figure 1-9 A mobile switching accumulation and loading mechanism, comprising: Rack 1; The longitudinal conveying mechanism 2 is arranged along the length of the frame 1. The longitudinal conveying mechanism 2 is composed of several roller conveyor belts 201. The bottom of several roller conveyor belts 201 near the feed end of the frame 1 is fixedly connected to form a movable adjustment seat 202. A transverse conveying mechanism 3 is provided, wherein the conveying direction of the transverse conveying mechanism 3 is set along the width direction of the frame 1, and the transverse conveying mechanism 3 is composed of several roller conveying chains 301 arranged at intervals. The transverse conveying mechanism 3 and the longitudinal conveying mechanism 2 are arranged alternately, and a gap is left between the transverse conveying mechanism 3 and the longitudinal conveying mechanism 2. In this embodiment, the frame 1 is used to support or install various components, and the longitudinal conveying mechanism 2 is used to transport and accumulate goods with pallets along the length of the frame 1 from the feed end of the frame 1 to the rear. Then, after the goods are accumulated, the transverse conveying mechanism 3 can transport the goods laterally and send them into the truck from the side.

[0032] There are several lifting mechanisms 4, and each lifting mechanism 4 is connected to the corresponding roller conveyor belt 201 so that it is higher or lower than the transverse conveyor mechanism. Furthermore, the transverse conveying mechanism 3 and the longitudinal conveying mechanism 2 are staggered, similar to two comb-like structures. The lifting mechanism 4 controls the raising and lowering of the longitudinal conveying mechanism 2. When the longitudinal conveying mechanism 2 is raised, it is exposed and higher than the transverse conveying mechanism 3. At this time, after the goods enter the loading device, they fall onto the longitudinal conveying mechanism 2, and the goods can be conveyed and accumulated along the longitudinal conveying mechanism 2 in a direction away from the feed end. When the longitudinal conveying mechanism 2 is lowered, it is hidden and lower than the transverse conveying mechanism 3. At this time, the goods follow the longitudinal conveying mechanism 2 and fall onto the transverse conveying mechanism 3. The transverse conveying mechanism 3 further feeds the goods in from the side of the truck.

[0033] The feeding adaptive system 9 includes an external torque detection device 901 and an internal torque detection device 902 disposed on the movable steering seat 202. The external torque detection device 901 is used to detect the equivalent friction coefficient at both sides and the middle position of the discharge end of the connected external conveying mechanism when unloaded. The internal torque detection device 902 is used to detect the equivalent friction coefficient at both sides and the middle position of the feed end of the movable steering seat 202 when unloaded. The movable steering seat 202 is provided with a plurality of friction force adjustment mechanisms 903. The adjustment mechanism 903 is used to adjust the surface friction coefficient at both sides and the middle position of the feed end of the movable steering seat 202. Before the goods enter the movable steering seat 202, the control system adjusts the friction adjustment mechanism 903 according to the equivalent friction coefficient deviation detected by the external torque detection device, so that the equivalent friction coefficient deviation at the feed end of the movable steering seat 202 tends to be consistent with the equivalent friction coefficient deviation at the discharge end of the external conveying mechanism. The equivalent friction coefficient deviation represents the difference in the equivalent friction coefficients experienced by the left and right sides of the pallet. In this embodiment, when goods with pallets enter the movable steering seat 202 from the external conveying mechanism, the bottom of the pallet has a U-shaped structure. The main contact points between the pallet and the movable steering seat 202 are concentrated in the middle and both sides of the movable steering seat 202. If there is a significant difference between the equivalent friction coefficient deviation of the external conveying mechanism and the equivalent friction coefficient deviation of the movable steering seat 202, the pulling force on the left and right sides of the pallet will be different, resulting in different torques. In this case, the goods will rotate horizontally. Therefore, an external torque detection device 901 and an internal torque detection device 902 are provided to detect the equivalent friction coefficient deviations on the left and right sides of the pallet, respectively. When the control system detects a deviation in the equivalent friction coefficient between the left and right positions of the discharge end of the external conveying mechanism, it adjusts the friction force adjustment mechanism 903 to make the equivalent friction coefficient deviation of the feed end of the movable steering seat 202 tend to be the same. This matches the difference in equivalent friction coefficient between the left and right sides of the same pallet at the feed end of the movable steering seat 202 with the difference in equivalent friction coefficient between the left and right sides of the same pallet at the discharge end of the external conveying mechanism. This makes the change in traction force on the left and right sides of the pallet before and after the transition more consistent, eliminating the rotational torque caused by the sudden change in friction coefficient deviation. This allows the goods to smoothly reach the movable steering seat 202 without causing the movable steering seat 202 to rotate at a large angle, preventing the goods from being severely deflected and unable to rotate through the movable steering seat 202.

[0034] Rotary bearing 5 is located near the feed end of the frame 1. The fixed end of the rotary bearing 5 is connected to the frame 1, and the rotating end of the rotary bearing 5 is connected to the bottom of the movable adjustment seat through the lifting mechanism 4. refer to Figure 3 The rotating bearing 5 is one of the core improvements in this embodiment. A gap exists between the transverse conveying mechanism 3 and the longitudinal conveying mechanism 2, providing a structural basis for the rotation of the longitudinal conveying mechanism 2. Since the goods have already been shaped by the preliminary shaping mechanism of the longitudinal conveying mechanism 2 upon arrival, the edge of the pallet only deviates slightly from the conveying direction of the longitudinal conveying mechanism 2. Therefore, this gap allows for small-angle rotation of the longitudinal conveying mechanism 2. In this embodiment, the bottoms of several roller conveyor belts 201 near the feed end of the frame 1 are fixedly connected to form a movable adjusting seat 202. This allows these roller conveyor belts 201 to be individually connected to the rotating bearing 5, achieving the effect that the frame 1 and the transverse conveying mechanism 3 remain stationary while the longitudinal conveying mechanism 2 can rotate. This rotation is used to adjust the direction of the goods on the pallet.

[0035] The ejection mechanism 6, in several quantities, is sequentially arranged on the side of the frame 1 and can be ejected in the width direction of the frame 1. When the goods pass through the movable adjustment seat 202, that is, after the pallet and goods are lifted by the lifting mechanism driving the movable adjustment seat, the corresponding ejection mechanism extends out and presses against the side wall of the pallet, thereby causing the pallet together with the movable adjustment seat to rotate to the correction position. In this embodiment, during the loading process, the loading device needs to push the goods into the truck via the transverse conveying mechanism 3 by pushing out the goods in the width direction of the frame 1 through the pushing mechanism 6. At the same time, after the goods with pallets are lifted together by the lifting mechanism 4, the movable adjusting seat 202 and the rotating bearing 5 are raised together. The goods, pallets, and movable adjusting seat 202 are in a rotatable state. The push plate provided by the pushing mechanism 6 gently presses the pallet forward. The edge of the pallet facing the push plate can be driven by the push plate to rotate the movable adjusting seat 202 by a certain angle to adjust it.

[0036] An angle locking device 7 is disposed at the position of the transverse conveying mechanism 3 corresponding to the movable adjusting seat 202. When the movable adjusting seat 202 is lifted by the lifting mechanism 4, the angle locking device 7 fixes the angle of the movable adjusting seat 202 after a certain period of time. When the lifting mechanism 4 drives the movable adjusting seat 202 to descend, the angle locking device 7 allows the movable adjusting seat 202 to rotate in the unlocked state. In this embodiment, after the push-out mechanism 6 adjusts the movable directional seat 202 by pressing the tray and causing it to rotate at a certain angle, the movable directional seat 202 is still in a state of free rotation. The movable directional seat 202 eventually needs to sink and return to its original position before the goods can be further transported through the longitudinal conveying mechanism 2. During the sinking and returning process of the movable directional seat 202, the angle may change arbitrarily again. Therefore, the angle locking device 7 is needed to lock the angle of the movable directional seat 202 within a corresponding time to maintain the adjusted direction and place the goods on the transverse conveying mechanism 3. Then, the angle locking device 7 is used to unlock the movable directional seat 202 so that it can return to the initial angle.

[0037] The rotary mechanism 8 is used to rotate the movable steering seat 202 to its initial position after the movable steering seat 202 is lowered by the lifting mechanism 4.

[0038] In this embodiment, the slewing mechanism 8 is used to enable the movable directional seat 202 to return to its initial angle, thereby keeping the movable directional seat 202 in the same conveying direction as the rest of the longitudinal conveying mechanism 2, so as to further perform the conveying operation.

[0039] In this embodiment, a movable directional seat 202 is formed by fixing the bottom of the roller conveyor belt 201 near the feed end, and a non-powered rotating bearing 5 is provided at the bottom, allowing the movable directional seat 202 to rotate freely around the vertical axis. When goods with pallets are conveyed to the movable directional seat 202, the push-out mechanism 6 presses against the side wall of the pallet, pushing the movable directional seat 202 and the goods together to rotate to the correction position. No additional rotary drive motor is required; the correction of the goods is achieved solely by the push-out mechanism 6. At the same time, the angle locking device 7 and the rotation mechanism 8 work together to realize the complete realization of the entire process.

[0040] Furthermore, the rotary mechanism 8 includes a first inclined surface 801 and a second inclined surface 802. The first inclined surface 801 is disposed at the bottom ends of both sides of the movable steering seat 202, and the second inclined surface 802 is disposed on the transverse conveying mechanism 3 and corresponds to the lower part of the movable steering seat 202. When the conveying direction of the movable steering seat 202 is along the length direction of the frame 1, the first inclined surface 801 and the second inclined surface 802 are arranged opposite each other in the vertical direction.

[0041] In this embodiment, reference Figure 5 When the movable steering seat 202 descends, the pressure of the cargo causes the first inclined surface 801 and the second inclined surface 802 to engage, generating a horizontal force that drives the movable steering seat 202 to automatically rotate back to its initial position. Simultaneously, the bottom ends of both sides of the movable steering seat 202 are provided with first inclined surfaces 801, allowing the movable steering seat 202 to narrow at its bottom after being driven upwards, providing a larger clearance for rotation.

[0042] Furthermore, the angle locking device 7 includes a hydraulic damper 701. The second inclined surface 802 is provided with several notches. The hydraulic damper 701 is provided on the side of the roller conveyor chain 301 below the notches. The movable end of the hydraulic damper 701 is connected to a locking block 702 through a universal bearing (not shown). The locking block 702 is provided with an electromagnetic mechanism. The first inclined surface 801 is made of metal. After the lifting mechanism 4 drives the movable adjusting seat 202 to rise, the hydraulic damper 701 drives the locking block 702 to rise slowly, making the angle between the movable adjusting seat 202 and the rotating bearing 5 adjustable. After the hydraulic damper 701 drives the locking block 702 to rise to the upper limit, the electromagnetic mechanism is energized, causing the locking block 702 to be attracted to the first inclined surface 801, thereby locking the angle between the movable adjusting seat 202 and the rotating bearing 5.

[0043] In this embodiment, the hydraulic damper 701, which cannot extend or retract quickly, is utilized to drive the locking block 702. When the lifting mechanism 4 drives the movable adjusting seat 202 to rise rapidly, the hydraulic damper 701 slowly extends and delays for a certain period of time to deliver the locking block 702 to the lower side of the first inclined surface 801. During this process, the electromagnetic mechanism cannot lock the angle of the movable adjusting seat 202 with the locking block 702. Therefore, the angle of the movable adjusting seat 202 can be adjusted by the action of the pushing mechanism 6 during this process. Then, the locking block 702 reaches the upper limit position and presses against the lower side of the first inclined surface 801. The electromagnetic mechanism is energized and attracts the first inclined surface 801, thereby locking the angle of the movable adjusting seat 202.

[0044] Furthermore, during the process of the lifting mechanism 4 driving the movable steering seat 202 to descend, the electromagnetic mechanism is de-energized to unlock the angle of the movable steering seat 202. Under the pressure of the weight of the cargo and the movable steering seat 202, the telescopic end of the hydraulic damper 701 is driven back to the lower limit position.

[0045] The purpose of the notch is to allow the hydraulic damper 701 to pass through the second inclined plane 802.

[0046] Furthermore, the cross-section of the movable steering seat 202 narrows after passing through the first inclined surface 801, and the frame 1 is equipped with a distance sensor. The sensing direction of the distance sensor is aligned with the position of the first inclined surface 801 when the movable steering seat 202 and the transverse conveying mechanism 3 are at the same height. After the distance sensor detects that the movable steering seat 202 is moving from bottom to top, the control system drives the electromagnetic mechanism to be energized. After the control system detects that the movable steering seat 202 is moving from top to bottom, the control system drives the electromagnetic mechanism to be de-energized.

[0047] In this embodiment, reference Figure 5 The cross-section of the movable directional seat 202 narrows after passing through the first inclined surface 801, forming a structure that is wider at the top and narrower at the bottom. When the sensing direction of the distance sensor is aligned with the position of the first inclined surface 801 at the same height as the movable directional seat 202 and the transverse conveying mechanism 3, the sensing direction of the distance sensor passes through the first inclined surface 801 as the movable directional seat 202 moves from bottom to top. During the upward movement of the movable directional seat 202, the direction of the distance sensor corresponds to the transition from the wider upper portion to the narrower lower portion of the cross-section of the movable directional seat 202, causing a sudden increase in the distance sensed by the sensor. Conversely, during the downward movement of the movable directional seat 202, the distance sensed by the sensor suddenly decreases. This principle can be used to control the energization or de-energization of the electromagnetic mechanism, thereby ensuring that the electromagnetic mechanism unlocks or locks onto the first inclined surface 801 at the appropriate time. Furthermore, including a transverse drive member 10, the frame 1 is provided with a plurality of slide grooves 101 along its width direction, the roller conveyor chain 301 is disposed in the slide grooves 101, and the transverse drive member 10 drives the push-out mechanism 6 and the transverse conveying mechanism 3 to extend synchronously toward the width direction of the frame 1.

[0048] In this embodiment, the roller conveyor chain 301 is set in the chute 101 of the frame 1. The chute 101 provides support and guidance for the extension direction of the transverse conveyor mechanism 3, ensuring that the transverse conveyor mechanism 3 can accurately align with the side of the truck container each time it extends.

[0049] Furthermore, the transverse drive component 10 includes a first rotating motor, and the frame 1 is provided with a transmission belt 1001 along its width direction. The first rotating motor drives the transmission belt 1001, and the transmission belt 1001 drives the ejection mechanism 6 and the transverse conveying mechanism 3.

[0050] The structure of the lateral drive component 10 can be referenced. Figure 2 A connecting seat 1002 is installed on the transmission belt 1001, which is connected to the ejection mechanism 6 and the roller conveyor chain 301. When the belt drives the connecting seat to move in the width direction of the frame 1, the ejection mechanism 6 and the transverse conveyor mechanism 3 are ejected synchronously.

[0051] Furthermore, the ejection mechanism 6 is disposed on the upper side of the frame 1 corresponding to the transverse conveying mechanism 3. The ejection mechanism 6 includes a plurality of first drive cylinders 601, which together drive a transverse push plate 602. The surface of the transverse push plate 602 is provided with a wear-resistant plate.

[0052] refer to Figure 2 In this embodiment, multiple first drive cylinders 601 jointly drive a transverse push plate 602. The pushing force at each point of the transverse push plate is evenly distributed, avoiding the push plate tilting or uneven force on the goods caused by single-point drive, and ensuring that the goods are aligned in the correct direction.

[0053] Preferably, the lowest point of the transverse push plate 602 is set at the height of the corresponding movable adjusting seat 202 of the frame 1 when it is raised to the upper limit position. In this structure, the transverse push plate 602 pushes against the bottom of the pallet, and during the process of the pallet being lowered onto the transverse conveying mechanism 3, the transverse push plate 602 can still remain in contact with the side of the pallet, and the wear-resistant plate can provide low friction so that the pallet can be lowered smoothly.

[0054] Furthermore, it includes several connecting plates 102, which are sequentially hinged to the side of the frame 1 where the ejection mechanism 6 is not provided. The connecting plates 102 are driven to swing up and down by the second drive cylinder 103 so as to dock with the corresponding truck.

[0055] In this embodiment, by swinging the connecting plate 102 up and down, when the truck is parked on the side of the loading device, the connecting plate 102 can be swung down so that the connecting plate is connected between the side of the truck and the loading device.

[0056] Furthermore, the gap between the transverse conveying mechanism 3 and the longitudinal conveying mechanism 2 limits the maximum rotation angle of the movable steering seat 202 to 5°.

[0057] In this embodiment, the movable adjusting seat 202 not only needs to receive goods with pallets, but also needs to adjust the goods in conjunction with the push plate. When the movable adjusting seat 202 is lifted, it is in a freely rotatable state. In order to receive goods smoothly, the maximum rotation angle of the movable adjusting seat 202 needs to be limited to 5° to prevent the movable adjusting seat 202 from rotating arbitrarily and losing its function of receiving goods.

[0058] Furthermore, the external torque detection device 901 or the internal torque detection device 902 includes a plurality of third drive cylinders 91. Each third drive cylinder 91 has a torque sensor 92 connected to its telescopic end. After being lifted by the third drive cylinder 91, the torque sensor 92 abuts against the discharge end of the corresponding external conveying mechanism or the feed end of the movable steering seat 202. The telescopic end of the third drive cylinder 91 is provided with a pressure sensor (not shown). The control system calculates the equivalent friction coefficient based on the signals from the torque sensor 92 and the pressure sensor.

[0059] In this embodiment, the external conveying mechanism is also a roller conveyor belt. The external torque detection device 901 can be set on the outside of the movable steering seat 202. After the external conveying mechanism is connected to the movable steering seat 202, the corresponding third drive cylinder 91 rises and abuts the corresponding torque sensor 92 against the end of the external conveying mechanism. The internal torque detection device 902 is set below the outermost roller of the movable steering seat 202. After the corresponding third drive cylinder 91 rises, the corresponding torque sensor 92 abuts against the outermost roller of the movable steering seat 202. At this time, the pressure N detected by the pressure sensor and the drag force F converted by the torque sensor 92 are obtained. The equivalent friction coefficient is calculated by F / N.

[0060] Furthermore, the outermost roller of the movable adjusting seat 202 is a friction adjusting roller 2021. The friction adjusting roller 2021 has a hollow structure inside and an elastic element 93 is embedded therein. The surface of the friction adjusting roller 2021 has a plurality of mounting grooves 2022 connected to the hollow structure along its axial direction. The surface of the friction adjusting roller 2021 is fitted with a plurality of friction rings 94 at equal intervals. The inner ring of the friction ring 94 passes through the mounting grooves 2022 and is connected to the elastic element 93. The friction adjusting roller 2021 is provided with sliding bearings 95 that can move left and right on both sides and in the middle. One end of the elastic element 93 is connected to the end of the friction adjusting roller 2021, and the other end of the elastic element 93 is connected to the inner ring of the sliding bearing 95. The movable adjusting seat 202 is equipped with a horizontally arranged fourth drive cylinder 96, which is used to drive the sliding bearing 95, thereby driving the elastic element 93 to move the friction ring 94 closer or apart.

[0061] In this embodiment, reference Figure 8-9 The elastic element 93 is a spring, and the surface of the friction rings 94 is provided with the same texture for generating friction. The friction rings 94 and the sliding bearing 95 can move left and right on the surface of the friction force adjusting roller 2021. The friction rings 94 are evenly spaced on the surface of the friction force adjusting roller 2021. Since only the bottom of the pallet's zigzag structure rests on the conveyor belt, the friction coefficient of the contact surfaces on both sides of the bottom of the pallet can be adjusted by adjusting the middle position and both sides of the friction force adjusting roller 2021 before the pallet enters the conveyor belt. The principle is that when the friction rings 94 are close together, the effective contact area between the pallet longitudinal beam and the friction force adjusting roller 2021 is directly increased by changing the axial density of the friction rings 94, thereby increasing the equivalent friction coefficient. When the friction rings 94 are separated, the equivalent friction coefficient is decreased. Adjusting the left and right position of the sliding bearing 95 by the fourth drive cylinder 96 can adjust the equivalent friction coefficient of the friction force adjusting roller 2021 on both sides of the pallet, creating a corresponding deviation in the equivalent friction coefficient.

[0062] Furthermore, a walking track 104 is provided on the ground, and a walking mechanism 105 that travels on the walking track 104 is provided at the bottom of the frame 1. Several loading stations are arranged side by side on the side of the frame 1.

[0063] In this embodiment, the frame 1 is configured as a walkable structure, and an external conveying mechanism is provided at the end of the walking track 104. The frame 1 walks to the external conveying mechanism via the walking mechanism 105 to receive the corresponding goods. Then, the frame 1 walks to the corresponding loading station via the walking mechanism 105 and loads the goods by pushing them into the truck laterally.

[0064] The control method in this embodiment includes: S0, after the external conveying mechanism is connected to the longitudinal conveying mechanism, the lifting mechanism 4 is controlled to lift the movable adjusting seat 202 and the rotating bearing 5 together. The friction force adjusting mechanism 903 is adjusted according to the equivalent friction coefficient deviation detected by the external torque detection device 901, so that the equivalent friction coefficient deviation at the feed end of the movable adjusting seat 202 is consistent with the equivalent friction coefficient deviation at the discharge end of the external conveying mechanism. S1, receiving goods with a pallet, the movable steering seat 202 is higher than the transverse conveying mechanism 3, and conveying the goods with the pallet to the center position of the movable steering seat 202; S2, control the ejection mechanism 6 to eject and press against the side wall of the tray, thereby rotating the tray together with the movable adjustment seat 202 to the correction position, and control the angle locking device 7 to fix the angle of the movable adjustment seat 202; S3, control the lifting mechanism 4 to lower the movable adjusting seat 202 and the rotating bearing 5 together, so that the goods with the pallet are temporarily placed on the transverse conveying mechanism 3, and at the same time, the movable adjusting seat 202 is rotated to the initial position by the rotating mechanism 8; S4, control the lifting mechanism 4 to drive all the roller conveyor belts 201 to rise, control the push-out mechanism 6 to retract, and transport the goods to the rear end of the longitudinal conveyor mechanism 2; S5, repeat S1~S4 multiple times, after the goods are accumulated on the longitudinal conveyor 2 to form a whole column of goods, control the longitudinal conveyor 2 to descend so that the whole column of goods is placed on the transverse conveyor 3, and push the goods with pallets from the side of the truck through the push-out mechanism 6.
