[0001] This invention relates to the field of packing and stacking equipment, and in particular to a multi-station automatic packing and stacking integrated equipment. Background Technology

[0002] In the wave of global manufacturing and logistics industry transformation towards intelligence and efficiency, the packaging and stacking links, as the key connection point between the end of the production chain and the beginning of the logistics chain, directly determine the smoothness of the entire production line and the economic efficiency of enterprise operation. Against this background, integrated, collaborative, and intelligent packaging and stacking equipment has gradually become the mainstream direction of the market. However, traditional manual packaging and stacking methods not only face the real dilemma of continuously rising labor costs and labor shortages, but also suffer from many problems such as low operating efficiency, poor stacking accuracy, high safety risks, and difficulty in ensuring operational consistency. At the same time, market demand is showing a trend of flexible production with multiple varieties and small batches, and consumers' requirements for product delivery speed and quality are also constantly increasing. This forces enterprises to seek more efficient, flexible and intelligent solutions to break through development bottlenecks. Although automatic packaging and stacking integrated equipment has emerged under the drive of such industry demand, the existing equipment has limited workstations and still cannot meet the demand for high-efficiency packaging and stacking. At the same time, the low stacking accuracy leads to damage to goods. Therefore, this paper proposes a multi-station automatic packaging and stacking integrated equipment that combines multiple operations to solve the above-mentioned technical problems.

[0008] As a further embodiment of the present invention, a stacking mechanism is provided between the four supports. The stacking mechanism includes two second slides, which are fixedly installed side by side on the top of the four supports. A second motor is fixedly installed at one end of each of the two second slides, and a second screw is fixedly installed at the output end of the second motor. A second ball nut is threaded onto the second screw. A third slide is fixedly installed between the two second ball nuts. A third motor is fixedly installed at one end of the third slide.

[0011] As a further embodiment of the present invention, a packaging mechanism is provided on the upper side of the unloading conveyor belt. The packaging mechanism includes an arch frame, which is fixedly installed on the upper side of the unloading conveyor belt. A rotary motor is fixedly installed on the upper side of the arch frame. A folding rod is fixedly installed on the output end of the rotary motor. A base is fixedly installed on one end of the folding rod. A film tube is sleeved on the base, and a pressure plate is fixedly installed on one side of the base for compacting the film tube.

[0013] As a further embodiment of the present invention, the film cylinder is rotatably connected to the base, and the pressure plate is made of high-elastic steel.

[0014] The beneficial effects of this invention are as follows: By setting up cargo conveyor belts, pallet conveyor belts and unloading conveyor belts, when several single workstations are connected in series, several cargo conveyor belts form a single cargo conveying space, while the pallet conveyor belts and unloading conveyor belts respectively carry and transport empty pallets and pallets with stacked goods. Pallets are continuously put onto the pallet conveyor belts through support platforms for accurate stacking and packaging of goods in the later stage. By setting up a conveyor mechanism, multiple different sensors work together with the conveyor belt to identify the position of goods on the goods conveyor belt, as well as pallet information and goods stacking progress information on the pallet conveyor belt and unloading conveyor belt, forming a precise and orderly goods stacking, packaging, feedback and transportation system. By setting a second ball nut, a third ball nut, and a fourth ball nut, and making the three ball nuts slide connected to the second slide block, the third slide block, and the fourth slide block respectively, when in use, only the second motor 302, the third motor 306, and the fourth motor 310 need to be controlled to make the hanger 313 move in three-dimensional space. The bottom end of the hanger 313 is rotatably connected to the clamp 314, which is controlled by the hydraulic telescopic rod 315 to realize the grabbing and delivery of goods. By setting up a cargo conveyor belt and a pallet conveyor belt between four supports, a cargo conveying, cargo sensing, and cargo stacking space is formed from bottom to top between four clamps. In use, the clamps are moved and controlled to pick up, move, and place the cargo on the cargo conveyor belt onto the pallet in sequence. Once the cargo stacking height reaches the height limit sensor, the stacked cargo will be further conveyed to the middle of the unloading conveyor belt for later packaging. By setting up a packaging mechanism, in which the film tube, together with the base and the folding rod, is driven by a rotary motor to rotate around the stacked goods, and the film is pressed by a pressure plate, one end of the film can be clamped to the goods. Further control of the rotary motor to make the film tube rotate around the stacked goods achieves the effect of film packaging of the stacked goods, thereby increasing the stability of the stacked goods during transportation. In summary, the entire multi-station automated packing and stacking integrated equipment has multiple functions including conveying, sensing, stacking, and packing. It can effectively automate various operations in the packing and stacking of goods, solving the problems of low efficiency and low accuracy in traditional packing and stacking operations. Moreover, because the position of the height limit sensor is adjustable, the stacking height of goods is controllable, reducing the dependence on operators and providing effective assistance in the packing and stacking process, making the packing and stacking work more convenient, faster, more automated, and more stable.

[0017] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0018] like Figure 1-10As shown, a multi-station automatic packaging and stacking integrated equipment includes several single-station platforms 1, and a conveying mechanism 2 is provided on each single-station platform 1. The conveying mechanism 2 includes two cargo conveyor belts 201, a pallet conveyor belt 202, and an unloading conveyor belt 203. The cargo conveyor belts 201 are used to transport goods, while the pallet conveyor belts 202 and 203 are used to receive and transport pallets. All three conveyor belts 201, 202, and 203 are fixedly installed on the upper side of the single-station platform 1. A cargo sensor 204 is fixedly installed on one side of the cargo conveyor belts 201, and a support platform 205 is fixedly installed on one side of the pallet conveyor belts 202. An electric telescopic rod 206 is fixedly installed on the upper side of the support platform 205, and a [missing information - likely a device or component] is fixedly installed on the output end of the electric telescopic rod 206. There is a push plate 207. Four brackets 208 are fixedly installed on the upper side of the single workstation 1. A fixing plate 209 is fixedly installed between two brackets 208. Two first slides 210 are fixedly installed side by side on one side of the fixing plate 209. A first motor 211 is fixedly installed at one end of the two first slides 210. A first screw 212 is fixedly installed on the output end of the first motor 211. A first ball nut 213 is threaded on the first screw 212. A height limit sensor 214 is fixedly installed on one side of the first ball nut 213. A pallet sensor 215 is fixedly installed between the pallet conveyor belt 202 and the unloading conveyor belt 203.

[0019] In this embodiment, both the pallet conveyor belt 202 and the unloading conveyor belt 203 are perpendicular to the cargo conveyor belt 201. The unloading conveyor belt 203 protrudes from the single workstation 1 to leave space for packaging goods.

[0020] Multiple single-station stations 1 are connected in series to form a multi-station automatic packaging, stacking and conveying system. The goods are continuously conveyed under the action of the goods conveyor belt 201. When the goods pass through the goods sensor 204, its position information will be acquired and automatically fed back to the stacking system, which will facilitate the subsequent clamping of the goods.

[0021] In this embodiment, one end of the support platform 205 is connected to the pallet conveyor belt 202, and the upper surface of the support platform 205 is 3cm higher than the upper surface of the pallet conveyor belt 202.

[0022] The support platform 205 is set 3cm above the upper surface of the pallet conveyor belt 202. When in use, the pallet is placed on it, and the electric telescopic rod 206 is further controlled to push the push plate 207, so that the pallet reaches the pallet conveyor belt 202 under the push of the push plate 207. At this time, the pallet sensor 215 obtains the pallet position information and automatically feeds it back to the stacking system, so that the goods can be stacked.

[0023] In this embodiment, the first ball nut 213 is slidably connected to the first slide block 210, and the two first motors 211 have the same driving effect, which is used to control the two height limit sensors 214 to lift or lower synchronously and set the maximum height of the goods stack.

[0024] Two first motors 211 synchronously control two height limit sensors 214, so that the two height limit sensors 214 are at the same height. When the height of the stacked goods reaches the scanning range of the height limit sensor 214, the height limit sensor 214 will automatically feed back to the stacking and conveying system, so that the pallet and goods are transferred to the unloading conveyor belt 203. When the pallet sensor 215 detects that the pallet has arrived at the middle of the unloading conveyor belt 203, it will automatically feed back to the packaging system, which facilitates the accurate packaging of the stacked goods in the later stage.

[0025] In this embodiment, a stacking mechanism 3 is provided between the four supports 208. The stacking mechanism 3 includes two second slides 301, which are fixedly installed side by side on the top of the four supports 208. A second motor 302 is fixedly installed at one end of each of the two second slides 301, and a second screw 303 is fixedly installed on the output end of the second motor 302. A second ball nut 304 is threaded onto the second screw 303. A third slide 305 is fixedly installed between the two second ball nuts 304. A third motor 306 is fixedly installed at one end of the third slide 305, and a third motor 306 is fixedly installed on the output end of the third motor 306. A third screw 307 is fixedly installed, and a third ball nut 308 is threaded onto the third screw 307. A fourth slide 309 is fixedly installed on one side of the third ball nut 308. A fourth motor 310 is fixedly installed on one end of the fourth slide 309. A fourth screw 311 is fixedly installed on the output end of the fourth motor 310. A fourth ball nut 312 is fixedly installed on one side of the fourth screw 311. A hanger 313 is fixedly installed on one side of the fourth ball nut 312. Two clamps 314 are rotatably mounted on one end of the hanger 313. A hydraulic telescopic rod 315 is rotatably mounted between the clamps 314 and the hanger 313.

[0026] The stacking mechanism 3 uses feedback information from the cargo sensor 204, pallet sensor 215, and height limit sensor 214 to control the second motor 302, the third motor 306, and the fourth motor 310 to move the hanger 313 in three-dimensional space. It also works with the hydraulic telescopic rod 315 and the clamp 314 to accurately grab the cargo on the cargo conveyor belt 201 and further accurately stack the cargo on the pallet.

[0027] In this embodiment, the second ball nut 304, the third ball nut 308 and the fourth ball nut 312 are respectively snapped and slidably connected to the second slide block 301, the third slide block 305 and the fourth slide block 309. The two second motors 302 have the same driving effect and are used to control the two ends of the third slide block 305 to slide synchronously.

[0028] Driven by the second motor 302 and the third motor 306, the third ball nut 308 moves freely on the plane, and driven by the fourth motor 310, the fourth ball nut 312 moves freely in the vertical direction, thereby achieving the effect of free movement of the hanger 313 in three-dimensional space.

[0029] In this embodiment, a horizontal plate is provided at one end of each of the two clamps 314. The horizontal plate is used to increase the friction with the goods. A goods conveyor belt 201 and a pallet conveyor belt 202 are located between the four supports 208.

[0030] When the hanger 313 reaches the set position, the two hydraulic telescopic rods 315 are controlled to extend and retract synchronously, which enables the clamp 314 to quickly clamp and place the goods. The shape of the clamp 314 ensures the stability of the goods gripping, while the movement space of the hanger 313 is limited between the four supports 208.

[0031] In this embodiment, a packing mechanism 4 is provided on the upper side of the unloading conveyor belt 203. The packing mechanism 4 includes an arch frame 401, which is fixedly installed on the upper side of the unloading conveyor belt 203. A rotary motor 402 is fixedly installed on the upper side of the arch frame 401. A folding rod 403 is fixedly installed on the output end of the rotary motor 402. A base support 404 is fixedly installed on one end of the folding rod 403. A film cylinder 405 is sleeved on the base support 404. A pressure plate 406 is fixedly installed on one side of the base support 404 to compact the film cylinder 405.

[0032] The packaging mechanism 4 uses the feedback information from the pallet sensor 215 to control the rotary motor 402 and, in conjunction with the folding rod 403, make the film tube 405 rotate around the stacked goods, thereby packaging the stacked goods and ensuring the stability of the stacked goods during subsequent transportation.

[0033] In this embodiment, the arch frame 401 is in the shape of an inverted U, and the rotary motor 402 is located directly above the unloading conveyor belt 203.

[0034] The arch frame 401 mounts the rotary motor 402 directly above the unloading conveyor belt 203, and the pallet with stacked goods will also arrive directly above the unloading conveyor belt 203. When the rotary motor 402 is driven, the front end of the folding rod 403 below it will support the base 404 to rotate around the periphery of the stacked goods.

[0035] In this embodiment, the film cylinder 405 is rotatably connected to the base 404, and the pressure plate 406 is made of high-elastic steel.

[0036] The membrane cylinder 405 and the base 404 are connected by a sleeve, so that the membrane cylinder 405 can be flexibly installed and removed on the base 404, which facilitates the replacement of the membrane cylinder 405. The high-elasticity pressure plate 406 acts on the outside of the membrane cylinder 405 to compact the membrane on it, which can prevent the membrane cylinder 405 from rotating on its own and prevent the membrane from falling off.

[0037] It should be noted that the present invention is a multi-station automatic packaging and stacking integrated equipment. In use, several single workstations 1 are connected in series according to the production capacity requirements, so that several cargo conveyor belts 201 form a continuous cargo conveying space. Each single workstation 1 is equipped with a pallet conveyor belt 202 and an unloading conveyor belt 203, and a support platform 205 is set on one side of the pallet conveyor belt 202. The pallet can be pushed onto the pallet conveyor belt 202 by the push plate 207 on the support platform 205, so that the cargo can be further stacked. Among them, cargo sensor 204 identifies the position of cargo on cargo conveyor belt 201, pallet sensor 215 identifies the position of pallets on pallet conveyor belt 202 and unloading conveyor belt 203, and height adjustable limit sensor 214 is used to set the cargo stacking height and identify the cargo stacking progress, providing accurate information for subsequent cargo stacking and packaging. By controlling the second motor 302, the third motor 306 and the fourth motor 310, the hanger 313 moves in three-dimensional space, and in conjunction with the hydraulic telescopic rod 315 and the clamp 314, the goods on the cargo conveyor belt 201 are precisely gripped and the goods are further precisely stacked on the pallet. After the goods are stacked, the pallet will be transported to the middle of the unloading conveyor belt 203. Space will be left on the pallet conveyor belt 202 for the next pallet of goods to be stacked. The above process will complete the operation of precise grabbing, stacking and transporting of stacked goods. The entire process is coordinated with the goods sensor 204, pallet sensor 215 and height limit sensor 214 to achieve the effect of multi-station automatic stacking. The rotary motor 402 is controlled to rotate the folding rod 403, causing the base 404 to rotate around the stacked goods. In use, a film tube 405 is placed on the base 404. The film end only needs to be clamped between the goods to further rotate the film tube 405 around the stacked goods, thereby achieving the packaging effect of the stacked goods and improving the stability of the stacked goods during subsequent transportation. After the film is wrapped, the film can be cut.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
