Description

Technical Field

[0001] This utility model relates to the field of automated pallet processing technology, and in particular to a pallet collection, palletizing and sending device. Background Technology

[0002] In modern manufacturing and logistics industries, pallets are an important material handling tool, widely used in warehousing, transportation, and production line logistics operations. Pallets are typically made of materials such as wood, plastic, and metal, and are designed to support and stack goods, enabling efficient handling by equipment such as forklifts and stacker cranes.

[0003] Pallet palletizing and separating are critical operations in automated production processes, directly impacting operational efficiency and safety. Traditional pallet palletizing systems typically rely on manual labor or semi-automated equipment for stacking and separating pallets, but this approach has limitations. Currently, pallet collection, palletizing, and separating are generally performed by forklifts, manual labor, or simple robotic arms, resulting in low efficiency and a high risk of improper operation. For example, manual operation involves significant labor intensity and carries risks such as equipment downtime, operational errors, and personal injury. Especially in high-density storage environments, where pallets are stacked at greater heights, disassembly and separation become even more difficult. Furthermore, due to long-term storage, pallet surfaces often accumulate dust and dirt, affecting not only pallet lifespan but also potentially product quality, particularly in industries like food and pharmaceuticals where pallet cleanliness requirements are even higher.

[0004] Furthermore, traditional pallet separation devices often require additional manual intervention when separating individual pallets, resulting in inefficient separation processes and a high risk of pallet damage. Existing equipment, when performing automated pallet separation, largely fails to effectively address the issue of pallet surface cleaning, thereby increasing the workload and labor costs associated with subsequent manual cleaning.

[0005] CN 219729818U discloses an automatic pallet machine for switching pallets in a palletizing robot. It includes a frame welded from square tubing, with a pallet working station forming a palletizing workspace on the front of the frame, and a pallet output station downstream of the pallet working station. It also includes a single-pallet input component that inputs pallets stored in the pallet bin one by one into the pallet working station, a pallet working station and pallet delivery station component that transports fully loaded pallets from the pallet working station to the pallet output station, and a pallet holding component. This equipment actively transports pallets that have been palletized from the robot's palletizing station to the pallet output platform, awaiting transfer by a forklift, and then automatically replenishes empty pallets at the palletizing station.

[0006] Although the aforementioned patent discloses automatic pallet stacking and separation of pallets, the overall structure is complex, the various devices of the equipment are arranged along the width direction, occupy a large area, involve a large number of cylinders, have high manufacturing costs, and do not have pallet cleaning function.

[0032] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] like Figures 1-4 The diagram shows a pallet collecting, palletizing, and sending device, comprising a frame 1, an air shower system 2, a lifting cylinder 3, a lifting assembly 4, clamping arms, and a clamping adjustment device 7. The air shower system 2, lifting cylinder 3, and clamping adjustment device 7 are all screwed onto the frame 1. The lifting cylinder 3 is connected to the lifting assembly 4 and is used to drive the lifting assembly 4 to move up and down. The clamping arms include a left clamping arm 5 and a right clamping arm 6, respectively located on both sides of the lifting assembly 4, and can move up and down together with the lifting assembly 4 under the drive of the lifting cylinder 3. The frame 1 is equipped with a roller conveyor line 8 and a detection device, enabling the pallets to be transported on the roller conveyor line 8 and detecting the position of the pallets. The clamping adjustment device 7 is located in the perforated area of ​​the roller conveyor line 8 to correct the position of the pallets and prevent uneven pallet stacking.

[0034] Specifically, in this embodiment, the frame 1 includes a base 11 and a mounting frame 12 connected to the base; the mounting frame 12 specifically includes two vertical rods, a horizontal rod between the vertical rods, and an inclined rod between the vertical rods and the base. The roller conveyor 8 is mounted on the base 11 and located within the mounting frame 12. The air shower system 2 is suspended and screwed onto the mounting frame 12 and located above the roller conveyor 8. Additionally, detection devices are provided on both sides of the frame 1 or both sides of the roller conveyor 8. These devices are used to trigger the clamping adjustment device 7 when the pallet travels along the roller conveyor 8 to the clamping adjustment device 7. At this time, the clamping adjustment device 7 actuates, pushing the pallet to the centered position. Preferably, the detection device is a photoelectric sensor.

[0035] In this embodiment, vertical guide sliding devices 9 are provided on both longitudinal bars of the mounting frame 12, for allowing the lifting assembly 4 to slide up and down along the mounting frame 12 under the action of the lifting cylinder 3. Preferably, the vertical guide sliding device 9 includes a vertical linear guide rail and a first slider that matches the vertical linear guide rail. First slider mounting plates 42 are provided on both sides of the back of the lifting assembly 4 at positions corresponding to the first slider. The first slider mounting plates 42 are threadedly connected to the first slider, thereby driving the lifting assembly 4 to move up and down as a whole through the first slider.

[0036] like Figure 5 and Figure 6 As shown: In this embodiment, the lifting assembly 4 is located between the clamping and adjusting device 7 and the air shower system 2, including a main frame 41, with a left clamping arm 5 and a right clamping arm 6 extending from both sides of the front of the main frame 41. The back of the main frame 41 is provided with two first slider mounting plates 42, a baffle mounting seat 43, a lifting cylinder mounting seat 44, and two transverse cylinder mounting seats 45. Preferably, the two first slider mounting plates 42 are respectively located at the two side edges of the main frame 41; the baffle mounting seat 43 is located at the center of the back of the main frame 41; the lifting cylinder mounting seat 44 is screwed onto the baffle mounting seat 43; one transverse cylinder mounting seat 45 is located between the baffle mounting seat 43 and one side of the first slider mounting plate 42, and the other transverse cylinder mounting seat 45 is located between the baffle mounting seat 43 and the other side of the first slider mounting plate 42.

[0037] The main frame 41 includes an upper crossbeam, a lower crossbeam, and a support rod between them. A set of transverse guide sliding devices 46 is provided on both sides of the front of the upper and lower crossbeams. Preferably, the transverse guide sliding device 46 includes two transverse linear guide rails on the upper and lower crossbeams, with an upper slider and a lower slider respectively matched on the upper and lower transverse linear guide rails. The upper and lower sliders are connected to a second slider mounting plate 48. The left clamping arm 5 is threadedly connected to the left side of the second slider mounting plate 48 via a connecting plate 51, and the right clamping arm 6 is threadedly connected to the right side of the second slider mounting plate 48 via a connecting plate. A limiting baffle 47 is provided in the center of the front of the main frame 41 to limit the pallets stacked on the roller conveyor line. The limiting baffle 47 is bolted to the upper and lower ends of the baffle mounting base 43 via a connecting assembly.

[0038] In this embodiment, the lateral movement of the left clamping arm 5 and the right clamping arm 6 is driven by two lateral cylinders 10. The fixed end of the lateral cylinder 10 is threadedly connected to the lateral cylinder mounting seat 45, and the two lateral cylinders 10 are located between the upper and lower crossbeams of the main frame 41. The second slider mounting plate 48 has a piston connecting seat at the center of its back side for connecting to the piston end of the lateral cylinder 10. The two lateral cylinders 10 can extend and retract to drive the left clamping arm 5 and the right clamping arm 6 to move towards each other or away from each other, forming an opening and closing action. The upper and lower sliders move along the lateral linear guide rail under the drive of the corresponding lateral cylinders 10.

[0039] In this embodiment, the left clamping arm 5 and the right clamping arm 6 have the same structure, both including a connecting rod 52 extending vertically along the front of the main frame 41, a clamping arm body 53 welded or screwed onto the connecting rod, and an insert plate 54 extending along the connecting rod 52; a reinforcing plate 55 is also provided between the clamping arm body 53 and the connecting plate 51. Specifically, the clamping arm body 53 includes two columns and at least two clamping arm beams disposed between the columns. The columns and clamping arm beams are preferably designed as channel steel structures, and the top of the columns is provided with a slope. The left clamping arm 5 and the right clamping arm 6 are provided with multiple sets of sensing devices at corresponding positions, that is, sensing devices are provided at each position of the pallet stacking. For example, multiple sets of photoelectric sensors are provided on the columns of the clamping arm body 53, each set of sensors corresponding to one layer of pallets, used to detect the number of pallets and provide feedback. Two insert plates 54 extend from the bottom surface of the connecting rod 52 of the left clamping arm 5 and the right clamping arm 6, used to embed into the hollowed-out parts of the edge of the pallet. The connecting rod 52 is welded or screwed onto the connecting plate 51, and then connected to the second slider mounting plate 48 through the connecting plate 51. Thus, driven by the transverse cylinder 10, and in combination with the upper and lower sliders, it can move smoothly along the transverse linear guide rail.

[0040] In this embodiment, the lifting assembly 4 is driven to rise and fall by the lifting cylinder 3. The fixed end of the lifting cylinder 3 is connected to the frame 1, and the piston end is connected to the lifting cylinder mounting base 44, that is, a mounting block 441 extends from the lifting cylinder mounting base, and the mounting block 441 is provided with a hole for connecting the piston end. Preferably, the lifting cylinder 3 is a multi-position cylinder for driving the lifting and falling and provides signal feedback. By selecting a multi-position cylinder model for the lifting cylinder 3, the lifting assembly 4 can be stopped at the set target position under the drive of the lifting cylinder 3. In this embodiment, two stopping points are preferably set, namely target position 1 and target position 2. Target position 1 is located at the second to last clamping plate at the bottom, so that the insert plates on the left clamping arm 5 and the right clamping arm 6 can be embedded in the edge cutout of the second to last clamping plate; target position 2 is located at the lowest point, that is, at the bottom clamping plate, so that the insert plates on the left clamping arm 5 and the right clamping arm 6 can be embedded in the edge cutout of the bottom clamping plate.

[0041] In this embodiment, the air shower system 2 is installed on the side of the frame away from the lifting assembly. The air shower system 2 is equipped with a blowing and dust collection system. When the pallet moves to the air shower system 2 via the roller conveyor, the air shower system 2 will activate its blowing and dust collection functions. The movement of the roller conveyor cleans the surface of the pallet and simultaneously collects the dust. It is understood that a detection sensor can be installed at the air shower system 2 to detect whether a pallet has entered the system.

[0042] In this embodiment, the clamping adjustment device 7 is located at a cutout in the roller conveyor line 8. Specifically, the roller conveyor line 8 has a cutout located below the lifting assembly 4. This cutout refers to removing at least one roller from the roller conveyor line 8 to create a gap for installing the clamping adjustment device 7. During installation, the clamping adjustment device 7 must ensure that the pallet can be clamped during transport. The specific structure of the clamping adjustment device 7 has been patented by the applicant (application number: 202422806971.7), and will not be described in detail here.

[0043] The working principle of this embodiment is as follows:

[0044] The pallet collection and palletizing process is as follows: When the first pallet enters from left to right (i.e., from the direction of the air shower system 2) via the roller conveyor line 8, it triggers the detection device after reaching the target position. The clamping adjustment device 7 then activates, pushing the pallet to the center position. Once the pallet is centered, the lifting cylinder 3 activates, driving the lifting assembly 4 and the left and right clamping arms 5 and 6 to descend to the target position 1. At this point, the left and right clamping arms 5 and 6 move in opposite directions under the drive of the two horizontal cylinders 10, forming an opening action. The lifting cylinder then continues to activate, driving the lifting assembly 4 and the left and right clamping arms 5 and 6 to descend to the target position 2. At this point, the left and right clamping arms 5 and 6 move towards each other under the drive of the two horizontal cylinders 10, clamping the pallet. Simultaneously, the insert plates 5 on the left and right clamping arms 5 and 6... 4. The clamping device is inserted into the cutout at the edge of the pallet to firmly hold the pallet. Then, the lifting cylinder 3 raises the lifting assembly 4, the left clamping arm 5, the right clamping arm 6, and the pallet back to the initial position. After that, the second pallet enters the roller conveyor line 8, and the clamping adjustment device 7 will center it again. The lifting cylinder 3 drives the first pallet down to the target position 1. The left clamping arm 5 and the right clamping arm 6 open, placing the first pallet on the newly entered second pallet for stacking. Then, the lifting cylinder 3 continues to move, driving the lifting assembly 4 and the left clamping arm 5 and the right clamping arm 6 down to the target position 2. The insert plates 54 on the left clamping arm 5 and the right clamping arm 6 are inserted into the cutout at the edge of the bottom pallet, lifting both pallets back to the initial position at the same time. This repetitive action completes the collection and stacking of the pallets.

[0045] The pallet separation and delivery process is as follows: First, the lifting cylinder 3 lowers the lifting assembly 4 and the left and right clamping arms 5 and 6 to the target position 1, causing the left and right clamping arms 5 and 6 to open. At this point, the pallet is transported from the right side by a forklift to the roller conveyor 8. Then, the lifting cylinder 3 continues to lower the lifting assembly 4 and the left and right clamping arms 5 and 6 to the target position 2. At this time, the roller conveyor 8 starts, and the pallet moves from right to left to the limit baffle 47. Multiple sets of sensors on the left and right clamping arms 5 and 6 then check the pallet's position. The number of pallets is detected and reported. Then, the lifting cylinder 3 moves the lifting assembly 4 and the right and left clamping arms 5 and 6 to the target position 1. Driven by two horizontal cylinders 10, the left and right clamping arms 5 and 6 move towards each other, clamping the pallets. Simultaneously, the insert plates 54 on the left and right clamping arms 5 and 6 embed into the cutouts on the edge of the second pallet below. At this point, the lifting cylinder 3 moves the lifting assembly 4, left and right clamping arms 5 and 6, and all the upper pallets except the bottom pallets, to the initial position, completing the separation of the bottom pallets from the other pallets. The roller conveyor 8 then restarts, transporting the separated pallets to other positions, completing the pallet dispatch. Afterwards, the lifting cylinder 3 moves the lifting assembly 4, left and right clamping arms 5 and 6, and the remaining pallets down to the target position 2, and the cycle repeats, completing the automatic pallet dispatch.

[0046] In addition, regardless of whether the pallet enters from left to right or from right to left, as long as the pallet moves to the air shower system 2 via the roller conveyor line 8, the air shower system 2 will start blowing and vacuuming, cleaning the surface of the pallet through the movement of the roller conveyor line 8, and collecting the dust at the same time.

[0047] In summary, this embodiment can achieve automated collection, palletizing, and individual dispatch of pallets; on the other hand, it can clean the pallet surface and collect dust while palletizing and dispatching.
