Technical Field

[0001] This invention relates to the field of loading and unloading equipment, and more particularly to a transportation device. Background Technology

[0002] A shuttle bus is an industrial handling vehicle that is widely used in ports, stations, airports, warehouses and other places where a pushing device is needed to load and unload goods.

[0003] Traditional shuttle buses mainly rely on manual labor for loading and unloading goods. However, this method is inefficient and poses significant safety hazards, potentially leading to injuries or fatalities. Furthermore, if the goods contain viruses, workers are susceptible to infection during the loading and unloading process as they come into direct contact with the goods.

[0004] Therefore, there is a need for transportation equipment that can automate the loading and unloading of goods, in order to reduce manual loading and unloading, decrease the frequency of contact between operators and goods, and improve the efficiency of loading and unloading.

[0008] When the transportation equipment provided in this embodiment of the invention is in operation, an item is placed on the bearing surface of the bearing device. The control module is used to cause the transmission module to drive the telescopic module to a first position.

[0019] As can be seen from the background technology, transportation equipment is needed to automate the loading and unloading of goods, reduce the frequency of contact between operators and goods, and improve the loading and unloading efficiency.

[0020] To address the aforementioned technical problem, embodiments of the present invention provide a transportation device, comprising: a carrying device including a carrying surface for carrying articles; a pushing device disposed within the carrying device, the pushing device comprising: a transmission module for providing transmission; a telescopic module located on the transmission module for moving under the drive of the transmission module, the telescopic module including a rotatable baffle, the rotatable baffle protruding from the carrying surface; and a control module for controlling the transmission module to move to a first position, for causing the baffle of the telescopic module to rotate when the transmission module drives the telescopic module to the first position, and for controlling the transmission module to drive the telescopic module to move along a first direction after the baffle rotates out.

[0021] When the transportation equipment provided in this embodiment of the invention is in operation, an item is placed on the bearing surface of the bearing device. The control module is used to cause the transmission module to drive the telescopic module to a first position. When the telescopic module reaches the first position, the control module causes the baffle of the telescopic module to rotate out. The rotated baffle protrudes from the bearing surface. The control module is also used to control the transmission module to drive the telescopic module to move along a first direction after the baffle rotates out. During the movement of the telescopic module along the first direction, the baffle of the telescopic module pushes the item to move along the first direction. After the item is placed, the control module can coordinate and control the transmission module and the telescopic module to push the item to move along the first direction, realizing automated loading and unloading of items, reducing the frequency of contact between operators and items, and improving the loading and unloading efficiency of items.

[0022] To make the above-mentioned objects, features and advantages of the embodiments of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0023] Figure 1 This is a functional block diagram of the transportation equipment of the present invention. Figure 2 This is a schematic diagram of the transportation equipment of the present invention.

[0024] The transport equipment, used to move an article along a first direction (x), includes: a carrying device 10, including a carrying surface for carrying the article; a pushing device disposed in the carrying device 10, the pushing device including: a transmission module 20 for providing transmission; a telescopic module 30 located on the transmission module 20 for moving under the drive of the transmission module 20, the telescopic module 30 including a rotatable baffle 3130 (e.g., Figure 6As shown), the deflector 3130 protrudes from the bearing surface after being unscrewed; the control module 40 is used to control the transmission module 20 to move to the first position, and to cause the deflector 3130 of the telescopic module 30 to unscrew when the transmission module 20 drives the telescopic module 30 to the first position, and is also used to control the transmission module 20 to drive the telescopic module 30 to move along the first direction after the deflector 3130 is unscrewed.

[0025] When the transportation equipment provided in this embodiment of the invention is in operation, an item is placed on the bearing surface of the bearing device 10. The control module 40 is used to cause the transmission module 20 to drive the telescopic module 30 to a first position. When the telescopic module 30 reaches the first position, the control module 40 causes the baffle 3130 of the telescopic module 30 to rotate out. After rotating out, the baffle 3130 protrudes from the bearing surface. The control module 40 is also used to control the transmission module 20 to drive the telescopic module 30 to move along a first direction after the baffle 3130 rotates out. During the movement of the telescopic module 30 along the first direction, the baffle 3130 of the telescopic module 30 pushes the item to move along the first direction. After the item is placed, the control module 40 can coordinate and control the transmission module 20 and the telescopic module 30 to push the item to move along the first direction, realizing automated loading and unloading of items, reducing the frequency of contact between operators and items, and improving the loading and unloading efficiency of items.

[0026] refer to Figure 3 The supporting device 10 is used to support an article. The article is placed on the supporting surface.

[0027] In this embodiment, the bearing device 10 includes: a support frame 100; and a plurality of rollers 101, which are arranged at intervals along the first direction (x) on the support frame 100, and the rollers 101 are rotatably engaged with the support frame 100 to provide the bearing surface.

[0028] In this embodiment, the roller 101 is used to provide the bearing surface, that is, the top surface of the roller 101 is higher than the top of the support frame 100, and correspondingly, the item placed on the bearing surface contacts the top of the roller 101.

[0029] The roller 101 is rotatably engaged with the support frame 100, and the roller 101 is used to provide a bearing surface. Compared with the case where the bearing surface is flat, the rolling friction is smaller. Therefore, when the pusher pushes the item located on the bearing surface, the item rolls forward on the roller 101, and the pushing force required for the item is smaller, which makes the output power of the pusher smaller and helps to reduce the energy consumption of the transportation equipment.

[0030] It should be noted that the carrying device 10 includes a tray (not shown in the figure), which is used to place items, and the pushing device pushes the items by pushing the tray in the carrying device 10.

[0031] refer to Figure 4 and Figure 5 , Figure 4 for Figure 2 Cross-sectional view at BB. Figure 5 for Figure 4 Cross-sectional view at point AA.

[0032] In this embodiment, the pushing device is disposed in the bearing device 10.

[0033] The propulsion device includes: the transmission module 20, which is used to provide power.

[0034] In this embodiment, the direction perpendicular to the first direction is the second direction (y); in the second direction, the transmission module 20 is located in the central region of the bearing device 10.

[0035] The transmission module 20 is located in the central area of ​​the carrying device 10. Accordingly, when the transport equipment is working, the item is placed on the tray of the carrying device 10, and the central area of ​​the tray is pushed by the transmission module 20, so that the item can move more smoothly in the first direction.

[0036] Specifically, when the transport equipment is in operation, the transmission module 20 is used to receive instructions from the control module 40 to drive the telescopic module 30 to move or stop moving in the first direction.

[0037] In this embodiment, the transmission module 20 includes a frame (not shown in the figure), the frame including a first track frame 2101 and a second track frame 2102 extending along a first direction and spaced apart in a second direction. The first track frame 2101 includes a first plate surface 2103 and a second plate surface 2104 that are perpendicular to each other. The second track frame 2102 includes a third plate surface 2105 and a fourth plate surface 2106 that are perpendicular to each other. The first plate surface 2103 and the third plate surface 2105 are coplanar, and the second plate surface 2104 and the fourth plate surface 2106 are located on the same side of the first plate surface 2103 and the third plate surface 2105. The second plate surface 2104 is located on the side of the first plate surface 2103 away from the third plate surface 2105, and the fourth plate surface 2106 is located on the side of the third plate surface 2105 away from the third plate surface 2105. One side of the first plate surface 2103; two first rotating rods 2107, arranged at both ends of the first track frame 2101 and the second track frame 2102 along a first direction, the first rotating rods 2107 extending along a second direction, and the two ends of the first rotating rods 2107 being rotatably connected to the second plate surface 2104 and the fourth plate surface 2106; a first rotating gear 2108, fixedly arranged on the first rotating rods 2107, and located in the semi-enclosed area formed by the first plate surface 2103 and the second plate surface 2104, and the semi-enclosed area formed by the third plate surface 2105 and the fourth plate surface 2106; a first conveyor chain 2109, meshing with the first rotating gear 2108; a first motor 2110, the output end of the first motor 2110 being connected to the first rotating rod 2107.

[0038] In this embodiment of the invention, the second plate surface 2104 and the fourth plate surface 2106 provide rotatable support for the first rotating rod 2107. The first rotating gear 2108 is rotatably fixed on the first rotating rod 2107, and the first rotating gear 2108 is located in the semi-enclosed area formed by the first plate surface 2103 and the second plate surface 2104, and the semi-enclosed area formed by the third plate surface 2105 and the fourth plate surface 2106, respectively. Because the first transmission chain 2109 meshes with the first rotating gear 2108, the first track frame 2101 and the second track frame 2102 define the transmission trajectory of the first transmission chain 2109 in the transmission module. When the transmission module 20 is in operation, the output end of the first motor 2110 drives the first rotating rod 2107 to rotate, the first rotating rod 2107 drives the first rotating gear 2108 to rotate, and the first rotating gear 2108 drives the first transmission chain 2109 to drive. Because the first rotating gear 2108 is located in the semi-enclosed area formed by the first plate surface 2103 and the second plate surface 2104, and the semi-enclosed area formed by the third plate surface 2105 and the fourth plate surface 2106, the first transmission chain 2109 drives in the semi-enclosed area. Therefore, the transmission module 20 can ensure that the first transmission chain 2109 runs along a predetermined trajectory and achieves smooth transmission.

[0039] In this embodiment, the first track frame 2101 and the second track frame 2102 in the frame extend along a first direction, and the first track frame 2101 and the second track frame 2102 are spaced apart in a second direction. When the transmission module 20 is working, a telescopic module 30 is connected to the first transmission chain 2109, and the telescopic module 30 is located in the area between the first track frame 2101 and the second track frame 2102. The telescopic module 30 is driven by the first transmission chain 2109 and moves between the first track frame 2101 and the second track frame 2102 along the first direction.

[0040] The semi-enclosed area formed by the first plate surface 2103 and the second plate surface 2104, and the semi-enclosed area formed by the third plate surface 2105 and the fourth plate surface 2106, provide space for the first rotating gear 2108 and also provide a transmission path for the first transmission chain 2109 in the first direction.

[0041] In this embodiment, the first plate surface 2103 and the second plate surface 2104 are perpendicular to each other, the third plate surface 2105 and the fourth plate surface 2106 are perpendicular to each other, the first plate surface 2103 and the third plate surface 2105 are coplanar, and thus the second plate surface 2104 and the fourth plate surface 2106 are parallel to each other. Since the first track frame 2101 and the second track frame extend along the first direction, and the first rotating rod 2107 extends along the second direction, the first rotating rod 2107 is perpendicular to the second plate surface 2104 and the fourth plate surface 2107. The first rotating rod 2107 can be rotatably connected to the second plate surface 2104 and the fourth plate surface 2107 at the same time.

[0042] Specifically, the second plate surface 2104 includes a first top plate 21041 and a first bottom plate 21042, and the first plate surface 2103 and the first top plate 21041 form an angle steel; the fourth plate surface 2106 includes a second top plate 21061 and a second bottom plate 21062, and the third plate surface 2105 and the second top plate 21061 form an angle steel; the two ends of the first rotating rod 2107 and the second rotating rod 2111 are respectively connected to the first bottom plate 21042 and the second bottom plate 21062.

[0043] In this embodiment, the first top plate 21041 and the first bottom plate 21042 are spaced apart, and the first bottom plate 21042 and the second bottom plate 21062 are spaced apart. During the process of pushing the item by the pushing device, the vibrations in the first rotating rod 2107 and the second rotating rod 2111 are not easily transmitted to the angle steel through the first bottom plate 21042 and the second bottom plate 21062, and correspondingly, the vibrations in the angle steel are not easily transmitted to the first bottom plate 21042 and the second bottom plate 21062. Therefore, the spaced-apart structure of the first top plate 21041 and the first bottom plate 21042, and the spaced-apart structure of the first bottom plate 21042 and the second bottom plate 21062, helps to improve the smoothness of the pushing process.

[0044] In other embodiments, the first top plate and the first bottom plate may also be an integral unit, and the first bottom plate and the second bottom plate may be an integral unit.

[0045] In this embodiment, the top of the frame is lower than the bearing surface, that is, lower than the top of the roller. This arrangement allows the item to contact the roller during the pushing device's movement, enabling the item to move in the first direction with a small pushing force.

[0046] The first rotating rod 2107 is used to obtain rotational inertia from the first motor 2110, thereby driving the first rotating gear 2108 to rotate.

[0047] Two first rotating rods 2107 are disposed at both ends of the first track frame 2101 and the second track frame 2102 along the first direction. A first rotating gear 2108 is fixed to the first rotating rods 2107, and the first transmission chain 2109 meshes with the first rotating gear 2108. Therefore, the distance between the first rotating rods 2107 in the first direction determines the transmission distance of the transmission module 20 to the telescopic module 30. A larger distance between the two first rotating rods 2107 results in a longer transmission distance between the transmission module 20 and the telescopic module 30.

[0048] As an example, the first rotating rod 2107 is rotatably connected to the second plate surface 2104 and the fourth plate surface 2106 via a bearing end cap and a bearing that mates with the bearing end cap. Specifically, the inner diameter of the bearing is fixedly fitted with the outer diameter of the first rotating rod 2107, and the outer diameter of the bearing is fixedly fitted with the bearing end cap.

[0049] The first rotating gear 2108 is used to mesh with the first transmission chain 2109 to realize the transmission of the first transmission chain 2109.

[0050] The first rotating gear 2108 is fixedly disposed with the first rotating rod 2107. As an example, the outer diameter of the first rotating rod 2107 is clearance-fitted or interference-fitted with the first rotating gear 2108. In other embodiments, a first keyway may be formed on the outer diameter of the first rotating rod, and a matching second keyway may be formed in the hole at the center of the first rotating gear. The first keyway and the second keyway are connected by a key to achieve transmission.

[0051] In this embodiment, the first rotating gear 2108 is located in the semi-enclosed area formed by the first plate surface 2103 and the second plate surface 2104, and the semi-enclosed area formed by the third plate surface 2105 and the fourth plate surface 2106. Correspondingly, when the transmission module 20 is working, the first transmission chain 2109 moves in the semi-enclosed area. The first plate surface 2103 and the second plate surface 2104 can protect the first transmission chain 2109 in the first track frame 2101 from being squeezed by the object, and the third plate surface 2105 and the fourth plate surface 2106 can protect the first transmission chain 2109 in the second track frame 2102 from being squeezed by the object.

[0052] The first motor 2110 is used to provide power during the transmission process. The transmission module 20 is used to receive instructions from the control module 40 to drive the telescopic module 30 to move or stop moving in a first direction. That is, the control module 40 controls the first motor 2110 to rotate forward, reverse, or stop rotating.

[0053] The transmission module 20 further includes: a second rotating rod 2111, which is disposed between the first rotating rods 2107 in the first direction; and a transmission wheel 2112, which is rotatably disposed on the second rotating rod 2111, and the transmission wheel 2112 corresponds to the first rotating gear 2108 in the second direction.

[0054] The second rotating rod 2111 is located between the first rotating rods 2107. Correspondingly, in the first direction, the conveying wheel 2112 is located between the first rotating gears 2108, and the conveying wheel 2112 corresponds to the first rotating gear 2108 in the second direction. Compared with the case where only the first rotating gear meshes with the first conveyor chain, in this embodiment of the invention, the conveying wheel 2112 is located between the first conveyor chains 2109. The conveying wheel 2112 serves to constrain the conveying path of the first conveyor chain 2109, and also supports the first conveyor chain 2109, making it less prone to sagging. This reduces the likelihood of meshing errors between the first conveyor chain 2109 and the first rotating gear 2108, which is beneficial to the smoothness of the first conveyor chain 2109's transmission and ensures that the first conveyor chain runs along a predetermined trajectory, thus achieving motion guidance.

[0055] In this embodiment, the first conveyor chain 2109 includes a roller chain.

[0056] The transmission module 20 further includes: a second motor 2113 located on the second plate 2104 and the fourth plate 2106; a connecting rod 2114 connected to the output end of the second motor 2113; and a tension gear 2115 rotatably disposed at one end of the connecting rod 2114 away from the output end of the second motor 2113, wherein the tension gear 2115 meshes with the first transmission chain 2109.

[0057] The tensioning gear 2115 meshes with the first transmission chain 2109. The rotation of the second motor 2113 drives the connecting rod 2114 to rotate, so that the tensioning gear 2115, which is rotatably connected to the connecting rod 2114, can tension the first transmission chain 2109. This makes it less likely for the gears of the first transmission chain 2109 and the first rotating gear 2108 to mesh incorrectly, which is beneficial to the smoothness of the transmission of the first transmission chain 2109.

[0058] It should be noted that the output end of the second motor 113 is perpendicular to the connecting rod 114, and the connecting rod 2114 is parallel to the second plate surface 2104. Therefore, when the output end of the second motor 2113 rotates, the area swept by the connecting rod 2114 is parallel to the second plate surface 2104. In other words, during the process of the connecting rod 2114 being rotated by the output end of the second motor 2113, the movement trajectory of the tension gear 2115 does not have a component in the second direction, which is beneficial to improving the stability of the first transmission chain 2109.

[0059] In this embodiment, the first rotating rod 2107 is located at the top of the frame, and the second rotating rod 2111 is located at the bottom of the frame.

[0060] The first rotating rod 2107 and the second rotating rod 2111 are located at the top and bottom of the frame, respectively. Correspondingly, the first rotating gear 2108 is located at the top of the frame, and the conveyor wheel 2112 is located at the bottom of the frame. The first conveyor chain 2109 has weight, and during the conveying process, the top of the first conveyor chain 2109 is prone to drooping due to its weight. The location of the first rotating rod 2107 and the second rotating rod 2111 at the top and bottom of the frame, respectively, helps to reduce the probability of the first conveyor chain 2109 at the top of the frame coming into contact with the conveyor wheel 2112, thus ensuring smooth transmission of the first conveyor chain 2109.

[0061] It should be noted that the tensioning gear 2115 is located outside the first transmission chain 2109, and the first rotating gear 2108 is located inside the first transmission chain 2109.

[0062] During the tensioning process of the first conveyor chain 2109 by using the tensioning gear 2115, the tensioning gear 2115 moves towards the top of the frame under the drive of the second motor 114, which can keep the first conveyor chain 2109 in a taut state, which is conducive to the accurate meshing of the first conveyor chain 2109 and the first rotating gear 2108, and improves the smoothness of the first conveyor chain 2109.

[0063] In this embodiment, the transmission module 20 further includes: a second rotating gear 2117 located on a first rotating rod 2107; a third rotating gear 2118 located at the output end of the first motor 2110; and a second transmission chain 2119 meshing with the third rotating gear 2118 and the second rotating gear 2117.

[0064] When the transmission module 20 is working, the first motor 2110 rotates, and the output end of the first motor 2110 drives the third rotating gear 2118 to rotate. The third rotating gear 2118 is connected to the second rotating gear 2117 through the second transmission chain 2119, so the first rotating rod 2107 rotates under the drive of the second transmission chain 2119, and the corresponding first rotating gear 2108 located on the first rotating rod 2107 rotates. The first rotating gear 2108 can drive the first transmission chain 2109 to move.

[0065] In this embodiment, the second rotating gear 2117 is located outside the region between the first rotating gears 2108.

[0066] Therefore, compared with the case where the second rotating gear is located between the first rotating gears, in this embodiment of the invention, the second rotating gear 2117 is located outside the area between the first rotating gears 2108. When the transmission module 20 is working, when the telescopic module 30 moves to both ends of the frame in the first direction, the telescopic module 30 will not collide with the second rotating gear 2117, which is beneficial to optimizing the transmission module 20 and ensuring the smooth movement of the first transmission chain 2109.

[0067] In this embodiment, the second conveyor chain 2119 includes a roller chain.

[0068] In this embodiment, the transmission module 20 further includes a bottom panel 2200, connected to the second plate surface 2104 and the fourth plate surface 2106, and the bottom panel 2200 is located between the top first transmission chain 2109 and the bottom first transmission chain 2109. When the transmission module 20 is working, when the first transmission chain 2109 is affected by the movement during the transmission process and the weight of the first transmission chain 2109 itself, the bottom panel 2200 is used to prevent the first transmission chain 2109 from sagging too much, so that the first transmission chain 2109 can be accurately engaged, which is beneficial to ensuring the smooth transmission of the first transmission chain 2109.

[0069] It should be noted that after an item is placed on the bearing surface, the transmission module 20 is used to drive the telescopic module 30 to a first position in a first direction. Furthermore, when the baffle 3130 of the telescopic module 30 is screwed in, the baffle 3130 is flush with or lower than the bearing surface.

[0070] During the process of the transmission module 20 reaching the first position, the baffle of the telescopic module 30 is in a screw-in state. Because the baffle 3130 is flush with or lower than the bearing surface, the baffle 3130 of the telescopic module 30 will not contact the item on the bearing surface. In other words, during the process of the transmission module 20 reaching the first position, the telescopic module 30 will not push the item.

[0071] Specifically, the telescopic module 30 moves in the area between the first track frame 2101 and the second track frame 2102.

[0072] It should be noted that the transmission module 20 further includes: a first baffle (not shown in the figure) and a second baffle (not shown in the figure), the first baffle and the second baffle extending along the second direction, and the first baffle and the second baffle respectively located at both ends of the frame in the first direction, and the first baffle and the second baffle are both connected to the first track frame 2101 and the second track frame 2102.

[0073] The first baffle and the second baffle are used to define the operating area of ​​the telescopic module 30 in the first direction.

[0074] refer to Figures 6 to 8 , Figure 6 This is a schematic diagram of the structure of the telescopic module 30 with the baffle rotated out; Figure 7 This is a schematic diagram of the structure in which the baffle of the telescopic module 30 is screwed in; Figure 8 This is a schematic diagram of the baffle plate.

[0075] The telescopic module 30 is located on the transmission module 20 and is used to move under the drive of the transmission module 20. The telescopic module 30 includes a rotatable baffle 3130, which protrudes from the bearing surface after being rotatable.

[0076] The deflector 3130 protrudes from the bearing surface after being unscrewed, enabling the deflector 3130 to push the item to move in the first direction.

[0077] In this embodiment, the first direction also includes a second position, and the first and second positions are respectively located at both ends of the telescopic module 30's movement path in the first direction. Specifically, the first and second positions are located on the first baffle and the second baffle, respectively.

[0078] In the first direction, the first position and the second position define the distance by which the telescopic module 30 is pushed by the transmission module 20, that is, the distance by which the item is pushed.

[0079] The pushing device further includes a sensor (not shown in the figure), which is disposed at the first position and the second position of the bearing device 10, for detecting whether the telescopic module 30 has reached the first position and the second position.

[0080] Once the telescopic module 30 reaches the first and second positions, the sensor will transmit the signal indicating that the telescopic module 30 has reached the first and second positions to the control module 40.

[0081] In this embodiment, the sensor includes a limit switch.

[0082] It should be noted that the sensor is located on the first baffle and the second baffle, and is also located between the first track frame 2101 and the second track frame 2102.

[0083] The telescopic module 30 includes: a fixing member; a linear drive mechanism 3120 connected to the fixing member, the linear drive mechanism 3120 including an output end 3121 capable of reciprocating along a straight line; a connecting rod 3200 including a first end 3201 and a second end 3202, the first end 3201 being rotatably connected to the output end 3121; and a baffle 3130 including an input end 3133 rotatably connected to the second end 3202, a free end 3132 opposite to the input end 3133, and a connecting portion 3131 located between the input end 3133 and the free end 3132, the baffle 3130 being rotatably connected to the fixing member through the connecting portion 3131.

[0084] In the telescopic module 30 provided in this embodiment of the invention, the first end 3201 of the connecting rod 3200 is rotatably connected to the output end 3121 of the linear drive mechanism 3120. The baffle 3130 includes an input end 3133 rotatably connected to the second end 3202. The fixing member is rotatably connected to the connecting portion 3131 of the baffle 3130. When the telescopic module 30 is working, the extension of the output end 3121 of the linear drive mechanism 3120 causes the first end 3201 of the connecting rod 3200 to move linearly. The second end 3202 of the connecting rod 3200 provides rotational inertia to the input end 3133. The baffle 3130 and the fixing member rotate at the connecting portion 3131, thereby the baffle 3130 rotates clockwise relative to the fixing member, realizing... The unscrewing of the baffle 3130 causes its free end 3132 to be higher than the top of the fixing member and the bearing surface, which facilitates the free end 3132 in pushing the object. After the object is pushed, the output end 3121 of the linear drive mechanism 3120 retracts, causing the first end 3201 of the connecting rod 3200 to move linearly. The second end 3202 of the connecting rod 3200 provides rotational inertia to the input end 3133. The baffle 3130 and the fixing member rotate at the connection 3131, thereby rotating the baffle 3130 counterclockwise relative to the fixing member, thus screwing the baffle 3130 in, so that the free end 3132 of the baffle 3130 is lower than the top of the fixing member and the bearing surface.

[0085] In this embodiment, the fixing member includes a first fixing part 3110 and a second fixing part 3160 located on one side of the first fixing part 3110; the linear drive mechanism 3120 is connected to the second fixing part 3160; the connecting part 3131 of the baffle 3130 is rotatably connected to the first fixing part 3110.

[0086] In this embodiment, the second fixing part 3160 is connected to the first fixing part 3110. In other embodiments, the second fixing member and the first fixing member may also be separable.

[0087] The output end 3121 of the linear drive mechanism 3120 is rotatably connected to the first end 3201 of the connecting rod 3200, so that the displacement of the output end 3121 of the linear drive mechanism 3120 can be transmitted to the first end 3201 of the connecting rod 3200.

[0088] In this embodiment, the linear drive mechanism 3120 includes: a fixed rod 3122, which has a fixed end (not shown in the figure) and a movable end (not shown in the figure) in the extending direction of the fixed rod 3122; and a telescopic rod 3123, which is slidably disposed on the movable end in the extending direction of the fixed rod 3122, and the end of the telescopic rod 3123 away from the fixed rod 3122 serves as the output end 3121 of the linear drive mechanism.

[0089] As an example, the telescopic rod 3123 is pneumatically powered and slidably disposed at the moving end of the fixed rod 3122, and the linear drive structure 3120 includes a pneumatic cylinder. In other embodiments, the telescopic rod may also be hydraulically powered and slidably disposed at the moving end of the fixed rod. As an example, the linear drive mechanism includes a hydraulic cylinder. In other embodiments, the linear drive mechanism may also include an electric push rod.

[0090] In this embodiment, the telescopic module 30 further includes a third rotating connector 3203, which is rotatably connected to both the output end 3121 and the first end 3201. During the operation of the telescopic module 30, there is no torque between the telescopic rod 3123 and the connecting rod 3200, which helps ensure the stable operation of the telescopic module 30.

[0091] Specifically, the third rotating connector 3203 includes a pin.

[0092] The connecting rod 3200 is used to transmit the displacement of the output end 3121 of the linear drive mechanism 3120 to the input end 3133 of the baffle 3130, providing the rotational inertia of the baffle 3130.

[0093] In this embodiment, the connecting rod 3200 is a single integral rod. In other embodiments, the connecting rod may further comprise two or three rotatably connected rods.

[0094] The input end 3133 is rotatably connected to the second end 3202 of the connecting rod 3200. During the operation of the telescopic module 30, the input end 3133 provides rotational inertia to the baffle 3130 relative to the connecting part 3131. During the operation of the telescopic module 30, there is no torque between the connecting rod 3200 and the baffle 3130, which helps to ensure the stable operation of the telescopic module 30.

[0095] In this embodiment, the input end 3133 of the baffle 3130 includes a first rotating hole 3301, and the telescopic module 30 further includes a first rotating connector 3140 that passes through the first rotating hole 3301 and the second end 3202. The first rotating connector 3140 is rotatably connected to the second end 3202 and the first rotating hole 3301.

[0096] The first rotating hole 3301 is used to rotatably connect the baffle 3130 to the first rotating connector 3140. Specifically, the baffle 3130 is rotatably connected to the second end 3202 of the connecting rod 3200 through the first rotating hole 3301.

[0097] The first rotating connector 3140 rotatably connects the second end 3202 to the input end 3133. In this embodiment, the position of the first rotating connector 3140 is the position of the output end 3121.

[0098] In this embodiment, the first rotating connector 3140 includes a pin. In other embodiments, the first rotating connector may also be other boss rotating connectors that can provide a clearance fit.

[0099] During the operation of the telescopic module 30, the baffle 3130 rotates through the connecting part 3131.

[0100] like Figure 8 As shown, in this embodiment, the connecting portion 3131, the input end 3133, and the free end 3132 of the baffle 3130 are separated by a dotted line.

[0101] The connecting part 3131 has a second rotating hole 3302, and the fixing member has a third rotating hole (not shown in the figure), with the second rotating hole 3302 and the third rotating hole corresponding to each other.

[0102] The telescopic module 30 includes a second rotating connector 3150, which passes through the second rotating hole 3302 and the third rotating hole, and is rotatably connected to both the connecting part 3131 and the first fixing part 3110.

[0103] The second rotating hole 3302 and the third rotating hole are used for the second rotating connector 3150 to pass through, and are used to determine the relative rotation fulcrum of the baffle 3130 and the first fixing part 3110.

[0104] The second rotating connector 3150 rotatably connects the connecting part 3131 to the first fixing part 3110, and the rotation point of the connecting part 3131 and the first fixing part 3110 is the position of the second rotating connector 3150.

[0105] In this embodiment, the second rotating connector 3150 includes a pin. In other embodiments, the second rotating connector may also be other boss rotating connectors capable of providing clearance fit.

[0106] During the operation of the telescopic module 30, when the baffle 3130 is rotated out, the free end 3132 is used to push the item to complete loading and unloading.

[0107] During the operation of the telescopic module 30, the first end 3201 of the connecting rod 3200 is rotatably connected to the output end 3121, and the second end 3202 of the connecting rod 3200 is rotatably connected to the input end 3133 of the baffle 3130. This resolves the interference caused by the change in distance between the output end 3121 and the input end 3133, allowing the output end 3121 of the linear drive mechanism 3120 to smoothly drive the baffle 3130 to rotate relative to the connecting part 3131. In other words, it can smoothly drive the baffle 3130 to rotate relative to the first rotating connecting member 3140.

[0108] It should be noted that the area near the first rotating hole 3301 in the input end 3133 of the baffle 3130 is an arc L (e.g., Figure 8 As shown), during the rotation of the baffle 3130, compared with the case where the input end has a square sharp corner, the input end 3133 is less likely to interfere with the rest of the structure.

[0109] It should be noted that the free end 3132 of the baffle 3130, away from the second rotating hole 3302, has a groove 3400. The groove 3400 is used to prevent the baffle 3130 from contacting the third rotating connector 3203 during the extension and retraction process, which helps to ensure the smooth rotation of the baffle 3130.

[0110] In this embodiment, the distance between the connecting part 3131 and the free end 3132 is greater than the distance between the connecting part 3131 and the input end 3133.

[0111] The distance relationship between the connecting part 3131, the free end 3132 and the input end 3133 is set such that, during the process of the baffle 3130 rotating out, the output end 3121 moves linearly, providing the rotational inertia of the input end 3133. The small linear displacement of the input end 3133 achieves a large linear displacement of the free end 3132, so that the length of the free end 132 extending out of the top of the fixing member is long enough, which is beneficial for the free end 3132 to push the object.

[0112] In this embodiment, the first rotating hole 3301 is closer to the linear drive mechanism 3120 than the second rotating hole 3302.

[0113] Compared to the case where the second rotating hole 3302 is farther away from the linear drive mechanism 3120 than the first rotating hole 3301, the connecting rod 3200 rotates at a smaller angle when the telescopic module 30 is working. This makes it less likely for large torque to exist between the output end 3121 and the first end 3201, and between the second end 3202 and the input end 3133, which is beneficial for the baffle 3130 to be screwed in and out smoothly.

[0114] refer to Figure 9 The diagram shows a structural schematic of the transmission module 20 and the telescopic module 30 connected by the transmission chain connection. The transmission module 20 further includes a transmission chain connection 270 located at both ends of the fixing member in the second direction, and the transmission chain connection 270 is fixedly connected to the first transmission chain 2109.

[0115] When the transport equipment is in operation, the first transmission chain 2109 of the transmission module 20 is connected to the telescopic module 30 through the transmission chain connection part 270, driving the telescopic module 30 to move in the first direction.

[0116] In this embodiment, the conveyor chain connection part 270 includes: a first side plate 2701 and a second side plate 2702 extending along a first direction and spaced apart in a second direction, and the first side plate 2701 and the second side plate 2702 are spaced apart from the fixing member.

[0117] The conveyor chain connection part 270 further includes a top plate 2703, located on top of the first side plate 2701 and the second side plate 2702, and the top plate 2703 is connected to the fixing member.

[0118] Specifically, the first conveyor chain 2109 is located between the first side plate 2701 and the second side plate 2702, and is fixedly connected to the first side plate 2701 and the second side plate 2702 by a pin 2704.

[0119] The control module 40 is used to control the transmission module 20 to move to the first position, to cause the baffle 3130 of the telescopic module 30 to rotate out when the transmission module 20 drives the telescopic module 30 to the first position, and to control the transmission module 20 to drive the telescopic module 30 to move along the first direction after the baffle 3130 rotates out.

[0120] The control module 40 can coordinate and control the transmission module 20 and the telescopic module 30 to push the item to move along the first direction, thereby realizing automated loading and unloading of the item, reducing the frequency of contact between the operator and the item, and improving the loading and unloading efficiency of the item.

[0121] In this embodiment, the control module 40 includes a field controller.

[0122] In this embodiment, the control module 40 is used to control the transmission module 20 to stop transmission when the telescopic module 30 reaches the first position, and is also used to control the baffle 3130 to rotate out after the transmission module 20 stops transmission.

[0123] The control module 40 stops the telescopic module 30 at the first position and rotates out the baffle 3130 for subsequently pushing the item to the second position.

[0124] Specifically, the control module 40 stops the first motor 2110 from rotating, thereby stopping the transmission module 20 from transmitting power; the control module 40 extends the output end 3121 of the linear drive mechanism 3120, thereby driving the first end 2201 of the connecting rod 3200 to rotate, and the second end 2202 of the connecting rod 3200 drives the baffle 3130 to rotate clockwise relative to the second rotating connector 3150, thereby causing the baffle 3130 to rotate out.

[0125] In this embodiment, the control module 40 is used to control the transmission module 40 to stop transmission when the telescopic module 30 reaches the second position, and is also used to control the baffle 3130 to screw in after the transmission module 20 stops transmission.

[0126] The control module 40 positions the telescopic module 30 in the second position, and the baffle 3130 is screwed in, so that the telescopic module 30 can subsequently move to the third position to prepare for the next pushing of the item.

[0127] Specifically, the control module 40 controls the retraction of the first end 3201 of the linear drive mechanism 3120, which drives the first end 3201 of the connecting rod 3200 to rotate. The second end 3202 of the connecting rod 3200 drives the baffle 3130 to rotate counterclockwise relative to the second rotating connector 3150, so that the baffle 3130 is screwed in.

[0128] In this embodiment, the control module 40 is used to cause the telescopic module 30 to reach the second position and then cause the baffle 3130 of the telescopic module 30 to be screwed in, so that the baffle 3130 after being screwed in is flush with or lower than the bearing surface.

[0129] After being screwed in, the baffle 3130 is flush with or lower than the bearing surface, so that when an item is placed on the bearing surface, the telescopic module 30 moves smoothly between the first and second positions under the drive of the control module 40, and the baffle 3130 will not push the item.

[0130] The control module 40 is used to cause the transmission module 20 to drive the telescopic module 30 to move to a third position in a standby state after the baffle 3130 is screwed in. The third position is located between the first position and the second position.

[0131] The control module 40 controls the transmission module 20 to drive the telescopic module 30 to the third position. The third position is located between the first and second positions, and is used so that after an item is placed on the bearing surface, it can reach the first position with a shorter movement distance.

[0132] Figure 10 This is a flowchart of the transportation equipment workflow, which is described below in conjunction with... Figure 10 The working process of the aforementioned transportation equipment is analyzed in detail.

[0133] Step S1: Control module 40 controls transmission module 20 to start, and transmission module 20 drives telescopic module 30 to the first position.

[0134] Specifically, the control module 40 controls the first motor 2110 in the transmission module 20 to rotate. The first motor 2110 drives the third rotating gear 2118 to rotate. The third rotating gear 2118 is connected to the second rotating gear 2117 through the second transmission chain 2119. Thus, the first rotating rod 2107 rotates under the drive of the second transmission chain 2117, and the corresponding first rotating gear 2108 located on the first rotating rod 2107 rotates. The first rotating gear 2108 can drive the first transmission chain 2109 to move. The first transmission chain 2109 moves to the first position through the transmission chain connecting part 270 and the telescopic module 30.

[0135] It should be noted that the rotation direction of the first motor 2110 is defined as forward rotation.

[0136] Step S2: The sensor is used to send a signal that the telescopic module 30 has reached the first position to the control module 40.

[0137] In this embodiment, the sensor includes a limit switch. When the telescopic module 30 touches the limit switch, the limit switch sends a signal that the telescopic module 30 has reached the first position to the control module 40.

[0138] Step S3: After the telescopic module 30 reaches the first position, the control module 40 stops the transmission module 20 from driving.

[0139] Specifically, the control module 40 controls the first motor 2110 in the transmission module 20 to stop rotating, thereby stopping the first transmission chain 2109 from transmitting.

[0140] In other embodiments, after the control module stops driving the transmission module, the transmission module transmits a signal to the control module to stop the telescopic module from moving.

[0141] Step S4: After the control module 40 stops driving the transmission module 20, the control module 40 causes the baffle 3130 of the telescopic module 30 to rotate out.

[0142] Specifically, the control module 40 controls the output end 3121 of the linear drive mechanism 3120 in the telescopic module 30 to extend. The output end 3121 drives the first end 3201 of the connecting rod 3200 to move linearly. The second end 3202 of the connecting rod 3200 provides rotational inertia to the input end 3133. The baffle 3130 and the fixing member rotate at the connection part 3131, so that the baffle 3130 rotates clockwise relative to the fixing member, realizing the extension of the baffle 3130. This makes the free end 3132 of the baffle 3130 higher than the top of the fixing member and higher than the bearing surface, which is beneficial for the free end 3132 to push the object.

[0143] It should be noted that after the control module 40 causes the baffle 3130 of the telescopic module 30 to rotate out, the telescopic module 30 transmits the signal of the baffle 3130 rotating out to the control module 40, which is used by the control module 40 to control the transmission module to drive.

[0144] Step S5: After the baffle 3130 of the telescopic module 30 is rotated out, the transmission module 20 is controlled to drive the telescopic module 30 to the second position.

[0145] Specifically, the control module 40 controls the first motor 2110 in the transmission module 20 to rotate. The first motor 2110 drives the third rotating gear 3118 to rotate. The third rotating gear 3118 is connected to the second rotating gear 3117 through the second transmission chain 2117. Thus, the first rotating rod 2107 rotates under the drive of the second transmission chain 2117, and the corresponding first rotating gear 2108 located on the first rotating rod 2107 rotates. The first rotating gear 2108 can drive the first transmission chain 2109 to move. The first transmission chain 2109 moves to the second position through the transmission chain connecting part and the telescopic module 30.

[0146] It should be noted that the rotation direction of the first motor 2110 is defined as reverse rotation. The reverse rotation of the first motor 2110 causes the telescopic module 30 to move in the opposite direction in the first direction.

[0147] Step S6: The sensor is used to send the signal that the telescopic module 30 has reached the second position to the control module 40.

[0148] In this embodiment, the sensor includes a limit switch. When the telescopic module 30 touches the limit switch, the limit switch sends a signal that the telescopic module 30 has reached the second position to the control module 40.

[0149] Step S7: After the telescopic module 30 reaches the second position, the control module 40 stops the transmission module 20 from driving.

[0150] Specifically, the control module 40 controls the first motor 2110 in the transmission module 20 to stop rotating, thereby stopping the first transmission chain 2109 from transmitting.

[0151] In other embodiments, after the control module stops driving the transmission module, the transmission module transmits a signal to the control module to stop the telescopic module from moving.

[0152] Step S8: After the control module 40 stops driving the transmission module 20, the control module 40 screws in the baffle 3130 of the telescopic module 30.

[0153] Specifically, the control module 40 controls the retraction of the output end 3121 of the linear drive mechanism 3120 in the telescopic module 30. The output end 3121 drives the first end 3201 of the connecting rod 3200 to move linearly. The second end 3202 of the connecting rod 3200 provides rotational inertia to the input end 3133. The baffle 3130 and the fixing member rotate at the connection part 3131, so that the baffle 3130 rotates counterclockwise relative to the fixing member, realizing the screwing in of the baffle 3130, so that the free end 3132 of the baffle 3130 is lower than the top of the fixing member and lower than the bearing surface.

[0154] It should be noted that after the baffle 3130 of the telescopic module 30 is screwed in, the telescopic module 30 transmits the signal of the baffle 3130 being screwed in to the control module 40, which is used by the control module 40 to control the transmission module to drive.

[0155] Step S9: After the baffle 3130 is screwed in, the transmission module 20 drives the telescopic module 30 to move to the third position, which is located between the first position and the second position in the first direction.

[0156] Specifically, the control module 40 controls the first motor 2110 in the transmission module 20 to rotate. The first motor 2110 drives the third rotating gear 3118 to rotate. The third rotating gear 3118 is connected to the second rotating gear 3117 through the second transmission chain 2117. Thus, the first rotating rod 2107 rotates under the drive of the second transmission chain 2117, and the corresponding first rotating gear 2108 located on the first rotating rod 2107 rotates. The first rotating gear 2108 can drive the first transmission chain 2109 to move. The first transmission chain 2109 moves to the third position through the transmission chain connecting part and the telescopic module 30.

[0157] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
