[0017] 1. The present invention includes a walking mechanism, a lifting mechanism and a frame, and a conveying mechanism, a horizontal arrangement mechanism and a stacking mechanism are sequentially arranged on the top of the frame. The present invention can replace manual transportation and stacking operations of packaging boxes, thereby improving the efficiency of transportation and stacking of packaging boxes, saving a lot of manpower, reducing the labor intensity of packing and the cost of logistics, and making the transportation of packaging boxes safer, avoiding the situation where the packaging boxes fall or bump due to accidents caused by manual handling, and then causing damage to the items in the packaging boxes, thereby avoiding unnecessary property losses.

[0018] 2. The conveying mechanism includes a belt conveyor and two guide rods. The two guide rods are provided with compensation plates. The compensation plates are connected with an adjustment unit. The adjustment unit includes a lead screw, a nut and two movable frames. The two movable frames are respectively connected with the corresponding guide rods. The lead screw drives the two movable frames to move synchronously in opposite directions. Under the action of the two guide rods, the packaging boxes are guided to the middle of the belt conveyor, and then transported from the belt conveyor to the horizontal mechanism and pushed into rows by the horizontal mechanism. Since the packaging boxes are sent from the belt conveyor to the same position of the horizontal mechanism, the packaging boxes will not interfere with the moving parts on the surface of the horizontal mechanism, ensuring the normal operation of the horizontal mechanism, thereby improving the loading efficiency and avoiding damage to the packaging boxes. A second plate is provided under the first plate of the adjustment unit. The synchronous belt between the second plate and the first plate can drive the first plate to move horizontally, thereby driving the two straightening rods to move synchronously in the same direction in the horizontal direction. The horizontal position of the opening between the two straightening rods is adjusted according to the packaging boxes of different specifications, so that the packaging boxes will not interfere with the moving parts on the surface of the horizontal mechanism after entering the horizontal mechanism.

[0019] 3. The horizontal row mechanism is provided with a main platform, a horizontal push plate that can be moved horizontally is provided above the main platform, and a longitudinal push plate that can be moved vertically and raised and lowered is provided on one side of the main platform. The packaging boxes sent by the conveying mechanism are pushed horizontally and pushed into rows on the main platform in turn, and are pushed to the stacking mechanism together by the longitudinal push plate for subsequent loading operations. This process does not require manual participation, which improves work efficiency and is not easy to cause damage to the packaging boxes. The horizontal push plate includes an upper horizontal push plate and a lower horizontal push plate. The upper horizontal push plate and the lower horizontal push plate can move synchronously in the same direction, and can also move separately. Before the last packaging box in the row of packaging boxes enters the main platform, the upper horizontal push plate and the lower horizontal push plate move in the opposite direction to press the two inner packaging boxes outward to prevent the two inner packaging boxes from being too close due to rebound, affecting the packaging boxes sent by the conveying mechanism, and ensuring that the last packaging box slides smoothly onto the main platform. Retractable main telescopic plates are also provided on both sides of the main platform, and rollers are elastically connected to the outside of the main telescopic plates, so that the present invention can be applied to carriages of different specifications.

[0020] 4. The stacking mechanism includes a frame, a stacking base plate, a stacking platform, a flip push plate, and a flip push box unit arranged on the stacking base plate for erecting the flip push plate and then moving longitudinally along the stacking platform to push out the rows of packaging boxes on the stacking platform. A lifting unit for driving the stacking base plate is provided on one side of the stacking base plate. After the horizontal row mechanism pushes the rows of packaging boxes to the stacking platform, the lifting unit drives the stacking platform to the height of the packaging box stacking. The flip push box unit erects the flip push plate, and then pushes the entire row of packaging boxes on the stacking platform to the left into the carriage to realize the stacking operation of the packaging boxes. Therefore, the stacking mechanism can replace manual work to stack the packaging boxes in the carriage of the truck in sequence, which improves the stacking efficiency. At the same time, the stacking is safe and reliable, and the phenomenon of the packaging boxes bumping and causing damage to the internal items will not occur. There are also movable platforms on both sides of the stacking platform, which move horizontally to adapt to the width of the carriage. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] For the convenience of description, in the following description, the direction consistent with the running direction of the belt conveyor 101 is referred to as "longitudinal", and the direction perpendicular to the running direction of the belt conveyor 101 in the horizontal plane is referred to as "transverse".

[0044] Example 1

[0045] like Figure 1 As shown, a walking type loader comprises a walking mechanism 4, a lifting mechanism 5 and a frame 6 connected in sequence from bottom to top. The walking mechanism 4 is a rubber crawler chassis currently used on crawler engineering vehicles, the lifting mechanism 5 is a scissor-type lifting platform, the frame 6 is a frame structure formed by connecting profiles, and the top of the frame 6 is provided with a conveying mechanism 1, a horizontal arrangement mechanism 2 and a stacking mechanism 3 in sequence from right to left in the longitudinal direction. The bottom of the lifting mechanism 5 is fixedly connected to the top of the walking mechanism 4.

[0046] The present invention travels into the compartment 8 of the truck through the traveling mechanism 4, and then the conveying mechanism 1 conveys the packaging boxes 7 delivered by the conveyor on the right side of the present invention to the left one by one to the horizontal arrangement mechanism 2. The horizontal arrangement mechanism 2 pushes the packaging boxes 7 delivered by the conveying mechanism 1 into a row one by one, and then delivers the entire row of packaging boxes 7 to the left to the stacking mechanism 3, and then the stacking mechanism 3 stacks the entire row of packaging boxes 7 from the inside to the outside and from the bottom to the top in the compartment 8 of the truck layer by layer. A horizontal linear slide 9 is provided between the top of the lifting mechanism 5 and the frame 6. The linear slide 9 can be an electric screw linear slide or a gear rack linear slide, which is used to adjust the horizontal position of the frame 6 and the conveying mechanism 1, the horizontal arrangement mechanism 2 and the stacking mechanism 3 installed on the frame 6, so that the conveying mechanism 1, the horizontal arrangement mechanism 2 and the stacking mechanism 3 are located in the middle position of the compartment 8.

[0047] Therefore, the present invention replaces manual labor in the conveying and stacking operations of the packaging boxes 7 with machinery, thereby improving the conveying and stacking efficiency of the packaging boxes 7, saving a lot of manpower, reducing the labor intensity of packing and the cost of logistics, and at the same time making the transportation of the packaging boxes 7 safer, avoiding the packaging boxes 7 from falling or bumping due to accidents in manual handling, thereby avoiding damage to the items in the packaging boxes 7, thereby avoiding unnecessary property losses.

[0048] Example 2

[0049] like Figures 1 to 7 As shown, the conveying mechanism 1 includes a longitudinal belt conveyor 101 fixedly connected to the frame 6 and two symmetrical rigid guide rods 103 arranged above the belt conveyor 101. The two guide rods 103 are arranged in a herringbone shape, and the symmetry planes of the two guide rods 103 coincide with the center line of the belt conveyor 101. The right ends of the two guide rods 103 are far away from each other, and the right ends of the two guide rods 103 are rotatably connected to the front and rear sides of the belt conveyor 101 respectively. The left ends of the two guide rods 103 are close to the horizontal mechanism 2 of the loader, and the frame 6 is provided with an adjustment unit for driving the left ends of the two guide rods 103 to move closer or farther.

[0050] The adjustment unit includes a rectangular first plate 105 arranged below the belt conveyor 101 and two movable frames 106 that are laterally slidably connected to the first plate 105. The first plate 105 is connected to the frame 6. The two movable frames 106 are respectively rotatably connected to the left ends of the corresponding guide rods 103. A horizontal lead screw 111 is rotatably connected to the first plate 105. Nuts 110 threadedly connected to the lead screw 111 are fixedly connected to the two movable frames 106. The threads of the two nuts 110 and the lead screw 111 are in opposite directions. A first motor 112 is fixedly connected to the first plate 105. The first motor 112 is a servo motor. The first motor 112 is connected to the lead screw 111 through a coupling.

[0051] Both movable frames 106 are C-shaped. The two movable frames 106 are symmetrically arranged with the belt conveyor 101 as the center. The two movable frames 106 are respectively buckled on both sides of the belt conveyor 101. The first flat plate 105 is arranged below the movable frames 106. The bottoms of the two movable frames 106 are slidingly connected to the first flat plate 105. The nut 110 is fixedly connected to the bottom of the corresponding movable frame 106. The upper ends of the two movable frames 106 are respectively rotatably connected to the corresponding guide rods 103.

[0052] Two groups of mutually parallel transverse first linear guide modules 108 are arranged between the two movable frames 106 and the first flat plate 105. The tracks of the first linear guide modules 108 are fixedly connected to the first flat plate 105. Each group of first linear guide modules 108 has two groups of sliders, and the two groups of sliders are respectively fixedly connected to the bottom of the corresponding movable frames 106.

[0053] A compensation sheet 116 is provided at the right end of each of the two guide rods 103 , and both ends of each compensation sheet 116 are rotatably connected to the corresponding guide rod 103 and the side of the belt conveyor 101 .

[0054] During the lateral translation of the movable frame 106, the distance between the hinge position of the movable frame 106 and the compensation plate 116 and the connection position between the right end of the guide rod 103 and the belt conveyor 101 will change. The compensation plate 106 can compensate for the change in distance. Therefore, by setting the compensation plate 106, it can be ensured that the left ends of the two guide rods 103 can open and close normally without getting stuck.

[0055] The working process of the conveying mechanism is:

[0056] First, the first motor 112 is operated to drive the two movable frames 106 to move synchronously in the opposite direction in the horizontal direction, and then drive the left ends of the two guide rods 103 to move in the opposite direction, so that the distance between the left ends of the two guide rods 103 corresponds to the size of the packaging box 7. The packaging box 7 is placed on the right end of the belt conveyor 101, and the belt conveyor 101 drives the packaging box 7 to move from right to left. Under the action of the two guide rods 103, the packaging box 7 is guided to the middle of the belt conveyor 101, and then conveyed from the middle of the left end of the belt conveyor 101 to the horizontal arrangement mechanism 2, and is pushed into a row by the horizontal arrangement mechanism 2.

[0057] Since the packaging box 7 is sent from the left end of the belt conveyor 101 to the same position in the middle of the horizontal mechanism 2, the packaging box 7 will not interfere with the moving parts on the surface of the horizontal mechanism 2, thereby ensuring the normal operation of the horizontal mechanism 2.

[0058] The left end of each guide rod 103 is rotatably connected to a longitudinal righting rod 107, and the upper parts of the two movable frames 106 are respectively fixedly connected to the corresponding righting rods 107. A smooth and flexible slide bar 102 is fixedly arranged on the inner side of each guide rod 103 and the inner side of the corresponding righting rod 107, and each guide rod 103 and the corresponding righting rod 107 are connected to the same slide bar 102. The slide bar 102 can be made of plastic or rubber.

[0059] When the packing box 7 moves to the left, it passes between the two straightening rods 107, so that the packing box 7 is straightened, making it easier for the horizontal row mechanism 2 to push the packing boxes 7 into a row.

[0060] A second flat plate 104 parallel to the first flat plate 105 is also provided below the first flat plate 105. The second flat plate 104 is fixedly connected to the frame 6. Two second linear guide modules 109 parallel to each other are provided between the second flat plate 104 and the first flat plate 105. The tracks of the second linear guide modules 109 are fixedly connected to the second flat plate 104. The sliders of the second linear guide modules 109 are fixedly connected to the first flat plate 105. The second flat plate 104 and the first flat plate 105 are slidably connected through the second linear guide modules 109. A second motor 114 is fixedly provided on the second flat plate 104. A driving synchronous pulley is fixedly connected to the output shaft of the second motor 114. A driven synchronous pulley is rotatably connected to the second flat plate 104. A synchronous belt 115 is wound around the driving synchronous pulley and the driven synchronous pulley. A belt connecting plate 113 is fixedly connected to the synchronous belt 115. The belt connecting plate 113 is fixedly connected to the first flat plate 105. When the second motor 114 rotates, the first flat plate 105 is driven to move horizontally through the synchronous belt 115.

[0061] When the first plate 105 moves laterally, it drives the two straightening rods 107 to move synchronously in the same direction laterally. The horizontal position of the opening between the two straightening rods 107 is adjusted according to the different specifications of the packaging boxes 7, so that the packaging boxes 7 will not interfere with the moving parts on the surface of the horizontal arrangement mechanism 2 after entering the horizontal arrangement mechanism 2.

[0063] Combination Figures 8 to 12 As shown, the horizontal mechanism 2 includes a horizontal mounting base plate 225 fixedly connected to the left side of the top of the frame 6, a horizontal main platform 210 fixedly connected above the mounting base plate 225 through a bracket, a horizontal push plate arranged above the main platform 210, and a first driving mechanism arranged on the mounting base plate 225 for driving the horizontal movement of the horizontal push plate.

[0064] The horizontal push plate includes an L-shaped lower horizontal push plate 216 and an L-shaped upper horizontal push plate 215 which are sequentially arranged above the main platform 210 from bottom to top. The upper horizontal push plate 215 is sleeved on the outer side of the lower horizontal push plate 216. The lower horizontal push plate 216 and the upper horizontal push plate 215 are independent of each other. Two horizontal horizontal push linear slides 224 are arranged on the mounting base plate 225. Both horizontal push linear slides 224 are lead screw linear slides driven by servo motors. The two horizontal push linear slides 224 are parallel to each other, and the slide seats of the two horizontal push linear slides 224 are fixedly connected to the mounting base plate 225. The sliders of the two horizontal push linear slides 224 are fixedly connected to the lower horizontal push plate 216 and the upper horizontal push plate 215, respectively.

[0065] A transverse longitudinal push plate 203 is provided between the main platform 210 and the conveying mechanism 1. The two ends of the longitudinal push plate 203 are telescopic auxiliary push plates 202 with scales. The total length of the longitudinal push plate 203 can be adjusted by telescoping the auxiliary push plates 202 according to the width of the carriage 8. The right side of the longitudinal push plate 203 is connected with longitudinal longitudinal push cylinders 201 near the front and rear ends. The push rods of the longitudinal push cylinders 201 are all facing left, and the left ends of the push rods of the longitudinal push cylinders 201 are fixedly connected to the longitudinal push plate 203 through the connecting plate 204. The two longitudinal push cylinders 201 are both located above the frame 6. The frame 6 is fixedly connected with a vertical fixed plate 209 at a position corresponding to the cylinder body of each longitudinal push cylinder 201. The outer side of each fixed plate 209 is slidably connected with a vertical movable plate 206, and the movable plates 206 are respectively fixedly connected to the cylinder body of the corresponding longitudinal push cylinder 201.

[0066] The middle part of the fixed plate 209 is rotatably connected with a driving gear 207, and the movable plate 206 is provided with vertical grooves at positions corresponding to the driving gears 207. The driving gears 207 are respectively located in the corresponding grooves, and the movable plates 206 are fixedly connected with vertical racks 208 meshing with the corresponding driving gears 207 in the grooves. The two fixed plates 209 are respectively arranged on both sides of the conveying mechanism 1, and the two driving gears 207 are connected through a transmission shaft arranged under the conveying mechanism 1, and a reduction motor connected to the transmission shaft is fixedly connected to one of the fixed plates 209.

[0067] When the reduction motor rotates, the active plate 206 is driven to move up and down through the driving gear 207 and the rack 208, and then the two longitudinal push cylinders 201 and the longitudinal push plate 203 move up and down. When the longitudinal push plate 203 moves upward, the longitudinal push plate 203 is higher than the upper horizontal push plate 215, and when the longitudinal push plate 203 moves downward, the longitudinal push plate 203 is lower than the main platform 210.

[0068] The working process of the horizontal mechanism 2 is:

The conveying mechanism 1 conveys the packaging box 7 from right to left to the middle of the main platform 210, and then the two horizontal push linear slides 224 operate, driving the upper horizontal push plate 215 and the lower horizontal push plate 216 to move synchronously in the same direction, pushing the packaging box 7 horizontally toward the direction close to the carriage 8 and pushing it into a row.

[0070] 2. Before the last packing box 7 in the row of packing boxes 7 enters the main platform 210, the two horizontal push linear slides 224 drive the upper horizontal push plate 215 and the lower horizontal push plate 216 to move in the opposite direction, pressing the two inner packing boxes 7 outward to prevent the two inner packing boxes 7 from being too close to each other due to rebound and affecting the packing boxes 7 delivered by the conveying mechanism 1.

[0071] 3. The reduction motor drives the longitudinal push plate 203 to move upward, so that the longitudinal push plate 203 is higher than the upper horizontal push plate 215, and then the two longitudinal push cylinders 201 are actuated to push the entire row of packaging boxes 7 to the left onto the stacking mechanism 3.

[0072] Therefore, the packaging boxes 7 delivered by the conveying mechanism 1 can be pushed horizontally and into rows in sequence through the horizontal row mechanism 2, and then sent to the stacking mechanism 3 together for subsequent loading operations. This process does not require manual participation, improves work efficiency, and is not easy to cause damage to the packaging boxes 7.

[0073] The two ends of the main platform 210 in the transverse direction are respectively slidably connected with the main telescopic plates 211 , and the mounting base plate 225 is provided with a second driving mechanism for driving the two main telescopic plates 211 to extend or retract in the transverse direction.

[0074] The second driving mechanism includes two parallel transverse extension rails 221, and each main telescopic plate 211 is fixedly connected to a connecting frame 223 at the bottom. The outer ends of the two extension rails 221 are respectively fixedly connected to the corresponding connecting frames 223 through connecting rods 220. The two extension rails 221 are respectively slidably connected to the mounting base plate 225 through corresponding sliders arranged on the mounting base plate 225, and each slider is fixedly connected to the mounting base plate 225 through a bracket. An extension reduction motor 218 is provided between the two extension slide rails 221 and is fixedly connected to the output axis on the mounting base plate 225. The output shaft of the extension reduction motor 218 is provided with a rotating arm 219. The middle part of the rotating arm 219 is fixedly connected to the output shaft of the extension reduction motor 218. A driving plate 222 is provided at the inner end of the two extension slide rails 221. A connecting rod 220 is also provided between the driving plate 222 and the corresponding extension slide rail 221. The two driving plates 222 are fixedly connected to the extension slide rail 221 through the corresponding connecting rod 220, and the two ends of the rotating arm 219 are respectively connected to the corresponding driving plate 222 in both rotation and sliding manner.

[0075] The driving plate 222 is provided with a longitudinal slide groove, and the outer end of the rotating arm 219 is fixedly connected with a slide pin that can slide in the slide groove. When the extension reduction motor 218 rotates, the extension slide rail 221 is driven to move horizontally through the rotating arm 219, and then the two main telescopic plates 211 are driven to move synchronously in the opposite direction, so that the two ends of the main telescopic plates 211 are as close to the side plates of the carriage 8 as possible, so that the horizontal arrangement mechanism 2 can be used for carriages 8 of different sizes.

[0076] A group of longitudinally arranged rollers 212 are provided on the outer side of each main telescopic plate 211 , and each group of rollers 212 is rotatably connected to a slot plate, which is elastically connected to the connecting frame 223 via a nitrogen spring 226 fixedly arranged on the connecting frame 223 .

[0077] After the main telescopic plate 211 is extended outward, the two sets of rollers 212 are respectively pressed against the side walls of the carriage 8, so that the packaging box 7 maintains the stability of the present invention when it is pushed horizontally to avoid shaking.

[0078] A vertical baffle 213 is provided on the side of the main platform 210 away from the conveying mechanism 1, and three vertical baffle cylinders 217 are provided under the mounting base plate 225. The cylinder bodies of the baffle cylinders 217 are fixedly connected to the bottom surface of the main platform 210, and the cylinder rods of the baffle cylinders 217 are upward and fixedly connected to the baffle 213.

[0079] When the conveying mechanism 1 conveys the packaging box 7 to the main platform 210, the baffle cylinder 217 operates to make the baffle 213 higher than the main platform 210, blocking the delivered packaging box 7 to prevent the packaging box 7 from jumping out of the main platform 210 to the left due to inertia, and at the same time ensuring that the packaging box 7 is neatly pushed into a row. When the packaging boxes 7 are discharged in a row, the baffle cylinder 217 drives the baffle 213 to move downward, so that the longitudinal push plate 203 can smoothly push the entire row of packaging boxes 7 onto the stacking mechanism 3.

[0080] A secondary platform 205 is provided on the side of the main platform 210 away from the conveying mechanism 1, and the baffle 213 is set in the gap between the main platform 210 and the secondary platform 205. The main platform 210 is flush with the secondary platform 205 or slightly higher than the secondary platform 205. The secondary platform 205 is connected to the stacking mechanism 3 and can move up and down with the stacking mechanism 3. Secondary telescopic plates 214 are provided at the front and rear ends of the secondary platform 205, and the secondary telescopic plates 214 are fixedly connected to the corresponding main telescopic plates 211 respectively.

[0081] Example 4

[0082] Combination Figures 13 to 18As shown, the stacking mechanism 3 is arranged at the packaging box output side on the left side of the horizontal row mechanism 2, and the stacking mechanism includes a vertically liftable rectangular stacking bottom plate 320 arranged on the left side of the frame 6, a rectangular stacking platform 304 arranged above the stacking bottom plate 320, a horizontal long strip flip push plate 302 arranged on the right side of the stacking platform 304, and a flip push box unit arranged on the stacking bottom plate 320 for erecting the flip push plate 302 and then moving it longitudinally along the stacking platform 304. The stacking bottom plate 320 is fixedly connected to the stacking platform 304 through a connecting vertical plate 332 arranged between the stacking bottom plate 320 and the stacking platform 304, and the stacking bottom plate 320 is arranged horizontally.

[0083] The right side of the stacking bottom plate 320 is connected with a lifting unit, and the lifting unit includes a lifting frame 305 arranged on the right side of the stacking bottom plate 320, and the lifting frame 305 is vertically slidably connected with the frame 6 through the first vertical slide rail module 311. The track of the first vertical slide rail module 311 is fixedly connected to the left side of the frame 6, and the slider of the first vertical slide rail module 311 is fixedly connected to the right side of the lifting frame 305.

[0084] The stacking base plate 320 is vertically slidably connected to the lifting frame 305 via a second vertical slide rail module 333 , the track of the second vertical slide rail module 333 is fixedly connected to the left side of the lifting frame 305 , and the slider of the second vertical slide rail module 333 is fixedly connected to the right side of the stacking base plate 320 .

[0085] Two longitudinal symmetrical and parallel groove rails 310 are fixedly connected to the top of the frame 6 on the right side of the lifting frame 305. The two groove rails 310 are made of C-shaped steel. A trolley 309 is arranged between the two groove rails 310. The wheels at both ends of the trolley 309 are respectively located in the grooves of the corresponding groove rails 310, so that the trolley can move along the groove rails 310.

[0086] The left side of the trolley 309 is rotatably connected to the first sprocket 308, the top of the frame 6 is rotatably connected to the second sprocket 315 at the left end, the bottom of the lifting frame 305 is rotatably connected to the third sprocket 312, the top of the lifting frame 305 is rotatably connected to the fourth sprocket 313, and the frame 6 is connected to a chain 306, one end of the chain 306 is fixedly connected to the frame 6 between the trolley 309 and the lifting frame 305, and the other end is fixedly connected to the right side of the stacking bottom plate 320 after passing through the first sprocket 308, the second sprocket 315, the third sprocket 312 and the fourth sprocket 313 in sequence.

[0087] The first sprocket 308, the second sprocket 315, the third sprocket 312, the fourth sprocket 313 and the chain 306 constitute a chain transmission unit, and the chain transmission units are two symmetrically arranged. The frame 6 is provided with a longitudinal lifting hydraulic cylinder 307, and the lifting hydraulic cylinder 307 is arranged between the two chain transmission units. The two ends of the lifting hydraulic cylinder 307 are respectively hinged to the frame 6 and the trolley 309, and the groove rail 310 is located below the pushing mechanism 2, so that the structure is more compact.

[0088] A horizontal strip plate 301 is further provided on the right side of the flip push plate 302 . The strip plate 301 is fixedly connected to the top surface of the connecting vertical plate 332 to fill the gap between the flip push plate 302 and the horizontal mechanism 2 .

[0089] After the horizontal row mechanism 2 pushes the rows of packaging boxes 7 to the stacking platform 304, the lifting hydraulic cylinder 307 is extended, and driven by the chain 306, the stacking bottom plate 320 is first raised, and when the stacking bottom plate 320 rises to the top of the lifting frame 305, the lifting frame 305 is driven to rise under the action of the limit block on the top of the lifting frame 305 until it reaches the stacking height of the packaging boxes 7. The flip pusher unit makes the flip pusher plate 302 stand up, and then pushes the entire row of packaging boxes 7 on the stacking platform 304 to the left into the carriage 8.

[0090] After the stacking platform 304 rises, the stacking platform 304 first rises to the top of the lifting frame 305, and then the lifting frame 305 drives the stacking platform 304 to rise together. Therefore, the lifting frame 305 will not be higher than the top of the stacking platform 304. Therefore, when stacking the packaging boxes 7 in the carriage 8, the lifting frame 305 will not hit the top of the carriage 8 of the truck. Therefore, the present invention can stack the packaging boxes 7 near the top of the carriage 8, and can fill the carriage 8 from bottom to top.

[0091] The stacking mechanism 3 can replace manual work to stack the packaging boxes 7 in the compartment 8 of the truck in sequence, thereby improving the stacking efficiency. At the same time, the stacking is safe and reliable, and the packaging boxes 7 will not collide with each other, causing damage to the internal items.

[0092] The right side of the stacking bottom plate 320 is also fixedly connected with a sub-platform bracket 314, and the sub-platform bracket 314 is fixedly connected to the bottom surface of the sub-platform 205 of the horizontal arrangement mechanism 2. When the stacking platform 304 is raised along with the lifting frame 305, the sub-platform bracket 314 is also raised, thereby preventing the sub-platform 205 located above the lifting frame 305 from affecting the raising of the lifting frame 305. The lifting frame 305 is arranged below the horizontal arrangement mechanism 2, so that the overall structure of the loader is compact, occupies less space, and is more flexible.

[0093] The flipping and pushing box unit includes a longitudinal pushing linear slide 318 longitudinally arranged on the stacking base 320, a longitudinal flipping slide 323 fixedly connected to one side of the pushing linear slide base 326 of the pushing linear slide 318, and a flipping swing arm 325 with one end rotatably connected to the pushing slider 322 of the pushing linear slide 318 close to the flipping slide 323. The pushing linear slide 318 is a screw linear slide driven by a servo motor.

[0094] The flip swing arm 325 is arranged longitudinally, and the other end of the flip swing arm 325 is close to the horizontal mechanism 2 and fixedly connected to the bottom surface of the flip push plate 302. A longitudinal flip chute 324 is provided on the inner side of the flip slide plate 323. The flip chute 324 extends downward at one end close to the horizontal mechanism 2 so that the flip chute 324 forms an L shape. A flip slide pin 328 is fixedly connected to the flip swing arm 325, and the flip slide pin 328 is located in the flip chute 324. When the flip push plate 302 is horizontal, the flip slide pin 328 is located at one end of the flip chute 324 close to the horizontal mechanism 2 and the flip slide pin 328 is lower than the rotation center of the flip swing arm 325. When the push slider 322 of the push linear slide 318 moves in the longitudinal direction away from the horizontal mechanism 2, the flip slide pin 328 first rises along the flip chute 324, and then slides in the flip chute 324 in the longitudinal direction away from the horizontal mechanism 2. During this process, one end of the flip swing arm 325 close to the horizontal row mechanism 2 flips upward by 90 degrees, so that the flip push plate 302 stands upright, and then moves in the longitudinal direction away from the flip push plate 302 .

[0095] The stacking platform 304 is provided with rectangular movable platforms 303 on both sides in the horizontal direction, the top surface of the movable platform 303 is flush with the stacking platform 304, and there is a gap between the movable platform 303 and the stacking platform 304. The movable platform 303 is fixedly connected to the top-pushing linear slide base 326, and the top-pushing linear slide base 326 is connected to the stacking bottom plate 320 for horizontal sliding. The stacking bottom plate 320 is provided with a horizontal driving unit for driving the top-pushing linear slide base 326 to slide horizontally.

[0096] There are four push linear slides 318, and correspondingly, the flip swing arms 325 connected to the four push linear slides 318 are respectively arranged on both sides of the two movable platforms 303. When the flip slide pin 328 slides along the flip slide groove 324 in a direction away from the horizontal row mechanism 2, the outer end of the flip swing arm 325 flips up and moves along the side of the movable platform 303.

[0097] In this embodiment, the two movable platforms 303 are driven to move horizontally by the horizontal driving unit, so as to adapt to the width of the carriage. When the horizontal arrangement mechanism 2 pushes the packaging box 7 onto the stacking platform 304 and the movable platform 303, the flip push plate 302 is in a horizontal state, so as to facilitate the passage of the packaging box 7. The flip push plate 302 can be erected and the box can be pushed only by the action of pushing the linear slide 318, which has a simpler structure and a lower failure rate.

[0098] The transverse drive unit includes a transverse drive motor 331 fixedly connected to the output axis in the middle of the stacking base plate 320, and the transverse drive motor 331 is a servo motor. Four push linear slides 318 are symmetrically arranged on both sides of the transverse drive motor 331 in two groups, with two in each group. The two transverse drive motors 331 in each group are fixedly connected by two mutually parallel transverse first transverse slide rails 316. A transverse rotating arm 330 is provided on the output shaft of the transverse drive motor 331, and the outer end of the transverse rotating arm 330 is provided with a transverse second transverse slide rail 319, one end of which is fixedly connected to the inner side of the push linear slide base 326 of the inner push linear slide 318.

[0099] The middle part of the transverse shift arm 330 is fixedly connected to the output shaft of the transverse drive motor 331, and the stacking base plate 320 is fixedly connected to the second transverse sliding block 327 under the second transverse sliding rail 319. The second transverse sliding rail 319 is slidably connected to the second transverse sliding block 327, and the other end of the second transverse sliding rail 319 is rotatably and slidably connected to the outer end of the transverse shift arm 330.

[0100] The second transverse slide rail 319 is fixedly connected to one end close to the transverse rotating arm 330 with an intermediate connecting plate 321, and the intermediate connecting plate 321 is provided with a longitudinal slide groove, and the slide groove is provided with a cylindrical pin which can slide longitudinally therein, and the cylindrical pin is fixedly connected to the outer end of the transverse rotating arm 330, thereby realizing both rotational and sliding connection between the second transverse slide rail 319 and the transverse rotating arm 330.

[0101] In this embodiment, two movable platforms 303 can be driven by one transverse driving motor 331 to achieve synchronous reverse movement of the two movable platforms 303 , with a compact structure, simple and reliable.
