Description
Technical Field
[0001] This invention relates to the field of palletizing equipment technology, and in particular to a palletizing machine for outer carton production. Background Technology
[0002] On the outer carton production line, stacking individual outer cartons into stacks according to certain rules and layers after production is a key subsequent process. Traditional stacking operations mostly rely on manual labor, which is labor-intensive, inefficient, and prone to damage to the cartons or uneven stacking due to improper operation, posing safety hazards. With the development of automation technology, various automated palletizing equipment has emerged in the market. However, many existing palletizers still have some functional shortcomings. For example, during the palletizing process, in order to ensure the stability of the stack, it is usually necessary to stagger the boxes of adjacent layers. The mechanism to achieve this function is often quite complex, and its reliability needs to be improved. Moreover, during the rotation process, the stacked boxes may shift or collapse due to inertia. In addition, when transporting goods to the palletizing station, it is a challenge to smoothly and accurately transfer a row of boxes from the conveyor line to the lifting mechanism. Common robotic arm gripping or pushing methods may cause the goods to shake or shift during the transfer, affecting the accuracy of subsequent gripping and stacking. After palletizing is completed, when sending out a fully loaded pallet, due to the friction between the pallet and the support plate, it is sometimes difficult to start and send out the heavy pallet smoothly by relying solely on the rotation of the output roller. This may cause the equipment to jam or require manual intervention, affecting the smoothness of the entire automated process. Summary of the Invention
[0003] To address the aforementioned technical problems, this invention discloses a palletizing machine for outer carton production that features high automation, stable operation, reliable staggered stacking of cartons, and efficient cargo transfer and output. The technical solution adopted by this invention is as follows: A palletizing machine for outer carton production includes a palletizing mechanism for stacking produced outer cartons. The palletizing mechanism includes a palletizing bin, in which a palletizing base plate is slidably installed. The palletizing mechanism is equipped with a feeding mechanism for feeding the produced outer cartons in and a conveying mechanism for conveying the stacked outer cartons out.
[0004] Furthermore, the palletizing mechanism includes a traverse motor fixedly installed on the palletizing bin body, a traverse lead screw rotatably installed on the palletizing bin body, the traverse lead screw being fixedly installed to the motor shaft of the traverse motor, a transverse guide column fixedly installed on the palletizing bin body, a vertical lead screw rotatably installed on the palletizing bin body, a threaded drive between the palletizing bottom plate and the vertical lead screw, a lifting motor fixedly installed at the bottom of the palletizing bin body, a worm gear fixedly installed on the motor shaft of the lifting motor, and a worm wheel fixedly installed at the bottom of the vertical lead screw, the worm wheel meshing with the worm gear.
[0005] Furthermore, a rotating motor is fixedly installed on the palletizing base plate, a rotating gear is fixedly installed on the motor shaft of the rotating motor, a bottom rotating plate is rotatably installed on the palletizing base plate, a central gear is fixedly installed below the bottom rotating plate, the central gear meshes with the rotating gear, and a palletizing base is placed on the bottom rotating plate.
[0006] Furthermore, a gripping frame is slidably mounted on the transverse guide post. The gripping frame and the transverse lead screw form a threaded transmission. Two gripping motors are fixedly mounted on the gripping frame. A gripping lead screw is fixedly mounted on the motor shaft of the gripping motor. The gripping lead screw is rotatably mounted on the gripping frame. A front and rear gripping plate are rotatably mounted on the transverse sides of the gripping frame. A lower gripping rod is fixedly mounted on the front and rear gripping plates. An upper gripping rod is rotatably mounted on the lower gripping rod. A lifting block is rotatably mounted on the upper gripping rod. The lifting block and the gripping lead screw form a threaded transmission.
[0007] Furthermore, side motors are fixedly installed on both longitudinal sides of the gripping frame, and side lead screws are fixedly installed on the motor shafts of the side motors. Two side gripping plates are slidably installed on the gripping frame, and the side gripping plates and the side lead screws form a threaded transmission.
[0008] After the lifting pallet raises a row of goods, the gripping frame is positioned above the goods. The gripping motor drives the gripping screw to rotate, causing the lifting block to descend. The lifting block, through the upper and lower gripping rods, drives the two front and rear gripping plates to rotate inward. Simultaneously, the side motor drives the side screw to rotate, causing the two side gripping plates to move inward. The two side gripping plates clamp the side ends of the row of goods, while the two front and rear gripping plates clamp the front and rear ends. Subsequently, the lifting pallet descends, and the traverse motor drives the traverse screw to rotate, causing the gripping frame to slide along the horizontal guide column. The lifting motor drives the worm gear to rotate, causing the worm wheel and vertical screw to rotate, raising the palletizing base and palletizing platform. This brings the palletizing platform into contact with the bottom of the goods. When there are goods on the palletizing platform... When the gripper arrives at the edge of the goods already placed on the palletizing base with the goods in its gripping frame, the gripping motor drives the gripping screw to rotate, causing the lifting block to rise. The upper and lower gripping rods then drive the two front and rear gripping plates to rotate outward, so that the two front and rear gripping plates no longer clamp the front and rear ends of the goods. Instead, the side gripping plates clamp a row of goods forward a short distance, allowing the newly placed goods to fit snugly against the existing goods on the palletizing base. When the palletizing base is full of goods, the rotating motor drives the rotating gear to rotate, causing the central gear, bottom rotating plate, and palletizing base to rotate 90 degrees. This allows the next layer of goods to be stacked alternately with the previously stacked goods, preventing the goods from collapsing. This process is repeated, stacking multiple layers of goods one by one from bottom to top on the palletizing base.
[0009] Furthermore, the feeding mechanism includes a lifting frame fixedly installed on the palletizing bin body, a column fixedly installed on the lifting frame, a lifting tray slidably installed on the column, a lifting motor fixedly installed on the lifting frame, and a lifting screw rotatably installed on the lifting frame. The lifting motor drives the lifting screw to rotate through a lifting belt, and the lifting tray and the lifting screw form a threaded transmission.
[0010] Furthermore, a feeding frame is fixedly installed next to the lifting frame, and multiple feeding rollers are rotatably installed on the feeding frame. A motor for driving the feeding rollers to rotate is installed inside the feeding frame. Multiple side electric cylinders are fixedly installed on both sides of the feeding frame, and side positioning plates are fixedly installed on the output end of the side electric cylinders. When the goods are placed on the feeding rollers, the multiple side positioning plates are located on both sides of the goods. A front electric cylinder is fixedly installed on the feeding frame, and a front stop block is fixedly installed on the output end of the front electric cylinder.
[0011] Furthermore, a transfer motor is fixedly installed on the feeding frame, a transfer column is rotatably installed on the feeding frame, a transfer wheel and a transfer rod are fixedly installed on the transfer column, the transfer motor drives the transfer wheel to rotate through the transfer belt, a suction cup frame is rotatably installed on the transfer rod, a balance transmission belt is wound around the suction cup frame and the transfer column, multiple suction cup assemblies are arranged below the suction cup frame, and multiple suction cups are arranged on the suction cup assemblies.
[0012] The front electric cylinder is always extended. During use, goods are placed on the feed roller, which transports them to the front stop. At this point, the goods are positioned between multiple side positioning plates. The side electric cylinders extend synchronously, causing the side positioning plates to extend and center the goods. Then, the suction cup assembly picks up the top of a row of goods. The transfer motor then rotates, driving the transfer wheel, transfer column, and transfer rod via the transfer belt. The suction cup frame and suction cup assembly bring the goods to the lifting pallet. The suction cup assembly then stops picking up the goods, placing them on the lifting pallet. During the movement of the suction cup frame, the transfer column drives the balance transmission belt, which in turn rotates the suction cup frame, ensuring the goods below remain stable and preventing wobbling, thus improving the smoothness of the transfer. Once the goods are on the lifting pallet, the transfer motor drives the transfer column, transfer rod, and suction cup frame back to their initial positions, ready for the next transfer. Then, the lifting motor drives the lifting screw via the lifting belt, raising the lifting pallet along with the goods, bringing the entire row of goods to the bottom of the gripper frame.
[0013] Furthermore, the conveying mechanism includes a delivery frame fixedly installed on the palletizing bin body, delivery motors fixedly installed on both sides of the delivery frame, a movable frame slidably installed on the delivery frame, delivery screws rotatably installed on both sides of the delivery frame, the movable frame and the delivery screws forming a threaded transmission, the delivery screws being fixedly installed to the motor shaft of the delivery motor, a delivery roller rotatably installed on the movable frame, a motor for driving the delivery roller to rotate being provided inside the movable frame, and a top plate fixedly installed on the movable frame.
[0014] Furthermore, fixing strips are fixedly installed on both sides of the palletizing base plate, two lifting rods are rotatably installed on the fixing strips, lifting blocks are rotatably installed on the lifting rods, and an ejection electric cylinder is fixedly installed on the lifting block. An ejection block is fixedly installed on the output end of the ejection electric cylinder.
[0015] In the initial state, the movable frame is on the outermost side, the top plate is not above the stacking base plate, and the lifting block and ejection block are at the bottom. The upper surface of the ejection block is lower than the lower surface of the bottom rotating plate. The ejection block does not affect the rotation of the bottom rotating plate and the stacking base. After the goods on the stacking base are stacked, the delivery motor drives the delivery screw to rotate, causing the movable frame and top plate to move towards the stacking base plate. When the top plate contacts the bottom of the ejection cylinder, the continued movement of the top plate will push the lifting block and ejection cylinder to move. In the initial state, the lifting rotating rod is not in a horizontal state, causing the two lifting rotating rods to rotate. The movement causes the lifting block, the ejector cylinder, and the ejector block to rise, so that the ejector block reaches the rear end of the palletizing base. At this time, the ejector block does not contact the rear end of the palletizing base. Then, the ejector cylinder retracts, and the ejector block moves a certain distance towards the rear end of the palletizing base before contacting the rear end of the palletizing base. This causes the ejector block to push the palletizing base onto the delivery roller. Then, the delivery roller is driven by a motor to rotate. The delivery roller, in conjunction with the thrust of the ejector block, delivers the palletizing base and the goods stacked on top of it, thus avoiding the inability to deliver the palletizing base and goods by simply rotating the delivery roller.
[0016] The beneficial effects of this invention compared with the prior art are: (1) The palletizing mechanism of this invention, through the bottom rotating plate and the palletizing base, can accurately rotate the entire palletizing base and the goods on it by 90 degrees after a layer of goods is stacked. This allows the adjacent two layers of goods to form an interlaced structure, which greatly improves the stability and integrity of the entire stack and effectively prevents the goods from tilting or collapsing due to uneven force during storage or transportation; (2) When the transfer motor drives the suction cup frame and the goods to swing, the balance transmission belt of the feeding mechanism of this invention can force the suction cup frame to produce a reverse compensating rotation, so that the goods adsorbed below it can always maintain a horizontal posture during the entire transfer process, which greatly reduces shaking and offset and ensures that the goods are accurately placed on the lifting pallet; (3) The clamping mechanism on the gripping frame of this invention is openable The front and rear gripping plates and the movable side gripping plates work together to form a structure. When it is necessary to place new goods close to the already stacked goods, the front and rear gripping plates can open first to release the constraints on the front and rear ends of the goods. Only the side gripping plates hold the goods and move them forward a short distance to achieve close placement. The operation of clamping and handling first and then releasing and fitting avoids interference between the mechanical structure and the already stacked goods, ensuring that each layer of goods can be arranged closely. (4) The conveying mechanism set in this invention cooperates with the top plate on the movable frame and the lifting rod, lifting block and other components on the stacking base plate to lift the push block from the low position to the working position and directly act on the rear end of the stacking base. Then the push cylinder retracts to provide a strong linear thrust, which forms a combined force with the rotational power of the delivery roller to smoothly deliver the heavy stacking base fully loaded with goods, overcoming the slippage or starting difficulties that may be caused by relying solely on the friction of the roller.

Detailed Implementation
[0027] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.
[0028] Example: Reference Figures 1-9 A palletizing machine for outer carton production includes a palletizing mechanism for palletizing the produced outer cartons 4. The palletizing mechanism includes a palletizing bin 101, a palletizing base plate 102 slidably installed inside the palletizing bin 101, and a feeding mechanism for feeding the produced outer cartons 4 into the palletizing mechanism and a conveying mechanism for conveying the palletized outer cartons 4 away.
[0029] like Figures 2-5As shown, the palletizing mechanism includes a lateral motor 103 fixedly installed on the palletizing bin body 101, a lateral lead screw 104 rotatably installed on the palletizing bin body 101, the lateral lead screw 104 being fixedly installed with the motor shaft of the lateral motor 103, a horizontal guide post 107 fixedly installed on the palletizing bin body 101, a vertical lead screw 106 rotatably installed on the palletizing bin body 101, a threaded drive between the palletizing base plate 102 and the vertical lead screw 106, a lifting motor 112 fixedly installed at the bottom of the palletizing bin body 101, a worm gear 113 fixedly installed on the motor shaft of the lifting motor 112, and a worm wheel 114 fixedly installed at the bottom of the vertical lead screw 106, the worm wheel 114 meshing with the worm gear 113.
[0030] like Figures 2-5 As shown, a rotating motor 110 is fixedly installed on the palletizing base plate 102, a rotating gear 111 is fixedly installed on the motor shaft of the rotating motor 110, a bottom rotating plate 108 is rotatably installed on the palletizing base plate 102, a central gear 109 is fixedly installed below the bottom rotating plate 108, the central gear 109 meshes with the rotating gear 111, and a palletizing base 105 is placed on the bottom rotating plate 108.
[0031] like Figures 2-5 As shown, a gripping frame 115 is slidably mounted on the horizontal guide post 107. The gripping frame 115 and the transverse lead screw 104 form a threaded transmission. Two gripping motors 116 are fixedly mounted on the gripping frame 115. A gripping lead screw 117 is fixedly mounted on the motor shaft of the gripping motor 116. The gripping lead screw 117 and the gripping frame 115 are rotatably mounted. A front and rear gripping plate 121 is rotatably mounted on the transverse sides of the gripping frame 115. A lower gripping rod 120 is fixedly mounted on the front and rear gripping plates 121. An upper gripping rod 118 is rotatably mounted on the lower gripping rod 120. A lifting block 119 is rotatably mounted on the upper gripping rod 118. The lifting block 119 and the gripping lead screw 117 form a threaded transmission.
[0032] like Figures 2-5 As shown, side motors 122 are fixedly installed on both longitudinal sides of the gripping frame 115, and side lead screws 123 are fixedly installed on the motor shaft of the side motors 122. Two side gripping plates 124 are slidably installed on the gripping frame 115, and the side gripping plates 124 and the side lead screws 123 form a threaded transmission.
[0033] After the lifting pallet 203 lifts a row of goods, the gripping frame 115 is positioned above the row of goods. The gripping motor 116 drives the gripping screw 117 to rotate, causing the lifting block 119 to descend. The lifting block 119 drives the two front and rear gripping plates 121 to rotate inward through the upper gripping rod 118 and the lower gripping rod 120. At the same time, the side motor 122 drives the side screw 123 to rotate, causing the two side gripping plates 124 to move inward. The two side gripping plates 124 clamp the side ends of the row of goods, and the two front and rear gripping plates 121 clamp the front and rear ends of the row of goods. Then, the lifting pallet 203 descends, the traverse motor 103 drives the traverse screw 104 to rotate, causing the gripping frame 115 to slide along the horizontal guide post 107. The lifting motor 112 drives the worm gear 113 to rotate, causing the worm wheel 114 and the vertical screw 106 to rotate, causing the palletizing base plate 102 and the palletizing base 105 to rise, so that the palletizing base 105 contacts the bottom of the goods. When there are goods on the palletizing base 105, when the gripping frame 115 arrives at the side of the goods already placed on the palletizing base 105 with the goods, the gripping motor 116 drives the gripping screw 117 to rotate, causing the lifting block 119 to rise. Through the upper gripping rod 118 and the lower gripping rod 120, the two front and rear gripping plates 121 are rotated outward, so that the two front and rear gripping plates 121 no longer clamp the front and rear ends of the goods, but only clamp a row of goods forward a short distance through the side gripping plate 124, so that the newly placed goods can fit with the original goods on the palletizing base 105. When the goods on the palletizing base 105 are filled with a whole layer, the rotating motor 110 drives the rotating gear 111 to rotate, causing the central gear 109, the bottom rotating plate 108, and the palletizing base 105 to rotate 90 degrees, so that the goods of the next layer can be placed alternately with the goods of the previous layer to prevent the goods from collapsing. In this way, multiple layers of goods are stacked on the palletizing base 105 one layer at a time from bottom to top.
[0034] like Figure 6 , Figure 7 As shown, the feeding mechanism includes a lifting frame 201 fixedly installed on the palletizing bin 101, a column 202 fixedly installed on the lifting frame 201, a lifting pallet 203 slidably installed on the column 202, a lifting motor 204 fixedly installed on the lifting frame 201, and a lifting screw 206 rotatably installed on the lifting frame 201. The lifting motor 204 drives the lifting screw 206 to rotate through the lifting belt 205, and the lifting pallet 203 and the lifting screw 206 form a threaded transmission.
[0035] like Figure 6 , Figure 7As shown, a feeding frame 215 is fixedly installed next to the lifting frame 201. Multiple feeding rollers 216 are rotatably installed on the feeding frame 215. A motor for driving the feeding rollers 216 to rotate is installed inside the feeding frame 215. Multiple side electric cylinders 217 are fixedly installed on both sides of the feeding frame 215. Side positioning plates 218 are fixedly installed on the output end of the side electric cylinders 217. When the goods are placed on the feeding rollers 216, the multiple side positioning plates 218 are located on both sides of the goods. A front electric cylinder 220 is fixedly installed on the feeding frame 215. A front stop block 219 is fixedly installed on the output end of the front electric cylinder 220.
[0036] like Figure 6 , Figure 7 As shown, a transfer motor 207 is fixedly installed on the feeding frame 215, a transfer column 210 is rotatably installed on the feeding frame 215, a transfer wheel 209 and a transfer rod 211 are fixedly installed on the transfer column 210, the transfer motor 207 drives the transfer wheel 209 to rotate through the transfer belt 208, a suction cup frame 213 is rotatably installed on the transfer rod 211, a balance transmission belt 212 is wound around the suction cup frame 213 and the transfer column 210, and multiple suction cup assemblies 214 are arranged below the suction cup frame 213, with multiple suction cups arranged on the suction cup assemblies 214.
[0037] The front electric cylinder 220 is always extended. During use, goods are placed on the feed roller 216, which transports the goods to the front stop 219. At this point, the goods are positioned between multiple side positioning plates 218. The side electric cylinders 217 extend synchronously, causing the side positioning plates 218 to extend. The goods are centered by the side positioning plates 218 on both sides. Then, the suction cup assembly 214 suctions the top of a row of goods. The transfer motor 207 then rotates, driving the transfer wheel 209, transfer column 210, and transfer rod 211 to rotate via the transfer belt 208. The suction cup frame 213 and suction cup assembly 214 bring the goods onto the lifting pallet 203. Afterward, the suction cup assembly 214 stops suctioning the goods, and the goods are placed... On the lifting pallet 203, during the movement of the suction cup frame 213, the rotation of the balance transmission belt 212 driven by the transfer column 210 drives the suction cup frame 213 to rotate, so that the goods under the suction cup frame 213 can always be in a stable state without shaking, thus improving the stability of the goods transfer. After the goods are placed on the lifting pallet 203, the transfer motor 207 drives the transfer column 210, transfer rod 211 and suction cup frame 213 back to the initial position, ready for the next transfer. Then, the lifting motor 204 drives the lifting screw 206 to rotate through the lifting belt 205, which drives the lifting pallet 203 to rise. The lifting pallet 203 rises with the goods, so that a row of goods reaches below the gripping frame 115.
[0038] like Figure 8 , Figure 9As shown, the conveying mechanism includes a delivery frame 301 fixedly installed on the palletizing bin 101. Delivery motors 302 are fixedly installed on both sides of the delivery frame 301. A movable frame 304 is slidably installed on the delivery frame 301. Delivery screws 303 are rotatably installed on both sides of the delivery frame 301. The movable frame 304 and the delivery screws 303 form a threaded transmission. The delivery screws 303 are fixedly installed on the motor shaft of the delivery motors 302. A delivery roller 305 is rotatably installed on the movable frame 304. A motor for driving the delivery roller 305 to rotate is provided inside the movable frame 304. A top plate 306 is fixedly installed on the movable frame 304.
[0039] like Figure 8 , Figure 9 As shown, fixing strips 307 are fixedly installed on both sides of the palletizing base plate 102. Two lifting rods 308 are rotatably installed on the fixing strips 307. Lifting blocks 309 are rotatably installed on the lifting rods 308. Pushing cylinders 310 are fixedly installed on the lifting blocks 309. Pushing blocks 311 are fixedly installed on the output end of the pushing cylinders 310.
[0040] In the initial state, the movable frame 304 is on the outermost side, the top plate 306 is not above the stacking base plate 102, and the lifting block 309 and the ejection block 311 are at the bottom. The upper surface of the ejection block 311 is lower than the lower surface of the bottom rotating plate 108. The ejection block 311 does not affect the rotation of the bottom rotating plate 108 and the stacking base 105. After the goods on the stacking base 105 are stacked, the delivery motor 302 drives the delivery screw 303 to rotate, causing the movable frame 304 and the top plate 306 to move towards the stacking base plate 102. When the top plate 306 contacts the bottom of the ejection cylinder 310, the continued movement of the top plate 306 will push the lifting block 309 and the ejection cylinder 310 to move. In the initial state, the lifting rotating rod 308 is not in a horizontal state, driving the two lifting rotating rods 309 and 300 to move. 08 rotates, thereby driving the lifting block 309, the push-out electric cylinder 310, and the push-out block 311 to rise, so that the push-out block 311 reaches the rear end of the palletizing base 105. At this time, the push-out block 311 is not in contact with the rear end of the palletizing base 105. Then, the push-out electric cylinder 310 retracts, and the push-out block 311 moves a certain distance towards the rear end of the palletizing base 105. After that, the push-out block 311 contacts the rear end of the palletizing base 105, driving the push-out block 311 to push the palletizing base 105 onto the delivery roller 305. Then, the delivery roller 305 is driven to rotate by the motor. With the push-out force of the delivery roller 305 and the push-out block 311, the palletizing base 105 and the goods stacked on it are delivered out, avoiding the inability to deliver the palletizing base 105 and the goods by simply rotating the delivery roller 305.
[0041] The working principle of the palletizing machine for outer carton production disclosed in this invention is as follows: The front electric cylinder 220 is always in the extended state. During use, the goods are placed on the feed roller 216, which transports the goods to the front stop 219. At this time, the goods are located between multiple side positioning plates 218. The side electric cylinders 217 extend synchronously, driving the side positioning plates 218 to extend. The goods are centered by the side positioning plates 218 on both sides of the goods. Then, the suction cup assembly 214 adsorbs the top of a row of goods. Subsequently, the transfer motor 207 rotates, driving the transfer wheel 209, transfer column 210 and transfer rod 211 to rotate through the transfer belt 208. The suction cup frame 213 and the suction cup assembly 214 bring the goods to the lifting pallet 203. The suction cup frame 213 is no longer attached to the goods. It is placed on the lifting pallet 203. During the movement of the suction cup frame 213, the transfer column 210 drives the rotation of the balance transmission belt 212, which in turn drives the suction cup frame 213 to rotate. This ensures that the goods under the suction cup frame 213 remain stable and do not shake, thus improving the stability of the goods transfer. After the goods are placed on the lifting pallet 203, the transfer motor 207 drives the transfer column 210, transfer rod 211 and suction cup frame 213 back to their initial positions, ready for the next transfer. Then, the lifting motor 204 drives the lifting screw 206 to rotate through the lifting belt 205, which drives the lifting pallet 203 to rise. The lifting pallet 203 rises with the goods, so that a row of goods reaches below the gripper frame 115.
[0042] After the lifting pallet 203 lifts a row of goods, the gripping frame 115 is positioned above the row of goods. The gripping motor 116 drives the gripping screw 117 to rotate, causing the lifting block 119 to descend. The lifting block 119 drives the two front and rear gripping plates 121 to rotate inward through the upper gripping rod 118 and the lower gripping rod 120. At the same time, the side motor 122 drives the side screw 123 to rotate, causing the two side gripping plates 124 to move inward. The two side gripping plates 124 clamp the side ends of the row of goods, and the two front and rear gripping plates 121 clamp the front and rear ends of the row of goods. Then, the lifting pallet 203 descends, the traverse motor 103 drives the traverse screw 104 to rotate, causing the gripping frame 115 to slide along the horizontal guide post 107. The lifting motor 112 drives the worm gear 113 to rotate, causing the worm wheel 114 and the vertical screw 106 to rotate, causing the palletizing base plate 102 and the palletizing base 105 to rise, so that the palletizing base 105 contacts the bottom of the goods. When there are goods on the palletizing base 105, when the gripping frame 115 arrives at the side of the goods already placed on the palletizing base 105 with the goods, the gripping motor 116 drives the gripping screw 117 to rotate, causing the lifting block 119 to rise. Through the upper gripping rod 118 and the lower gripping rod 120, the two front and rear gripping plates 121 are rotated outward, so that the two front and rear gripping plates 121 no longer clamp the front and rear ends of the goods, but only clamp a row of goods forward a short distance through the side gripping plate 124, so that the newly placed goods can fit with the original goods on the palletizing base 105. When the goods on the palletizing base 105 are filled with a whole layer, the rotating motor 110 drives the rotating gear 111 to rotate, causing the central gear 109, the bottom rotating plate 108, and the palletizing base 105 to rotate 90 degrees, so that the goods of the next layer can be placed alternately with the goods of the previous layer to prevent the goods from collapsing. In this way, multiple layers of goods are stacked on the palletizing base 105 one layer at a time from bottom to top.
[0043] In the initial state, the movable frame 304 is on the outermost side, the top plate 306 is not above the stacking base plate 102, and the lifting block 309 and the ejection block 311 are at the bottom. The upper surface of the ejection block 311 is lower than the lower surface of the bottom rotating plate 108. The ejection block 311 does not affect the rotation of the bottom rotating plate 108 and the stacking base 105. After the goods on the stacking base 105 are stacked, the delivery motor 302 drives the delivery screw 303 to rotate, causing the movable frame 304 and the top plate 306 to move towards the stacking base plate 102. When the top plate 306 contacts the bottom of the ejection cylinder 310, the continued movement of the top plate 306 will push the lifting block 309 and the ejection cylinder 310 to move. In the initial state, the lifting rotating rod 308 is not in a horizontal state, driving the two lifting rotating rods 309 and 300 to move. 08 rotates, thereby driving the lifting block 309, the push-out electric cylinder 310, and the push-out block 311 to rise, so that the push-out block 311 reaches the rear end of the palletizing base 105. At this time, the push-out block 311 is not in contact with the rear end of the palletizing base 105. Then, the push-out electric cylinder 310 retracts, and the push-out block 311 moves a certain distance towards the rear end of the palletizing base 105. After that, the push-out block 311 contacts the rear end of the palletizing base 105, driving the push-out block 311 to push the palletizing base 105 onto the delivery roller 305. Then, the delivery roller 305 is driven to rotate by the motor. With the push-out force of the delivery roller 305 and the push-out block 311, the palletizing base 105 and the goods stacked on it are delivered out, avoiding the inability to deliver the palletizing base 105 and the goods by simply rotating the delivery roller 305.
