Description

Technical Field

[0001] This invention relates to a logistics machine, specifically to a receiving and stacking device for use in automated loading equipment. Background Technology

[0002] A survey of several cement plants revealed that while domestic cement plants have achieved a high level of automation, many processes still rely on manual labor, including cement loading. The high cost of labor and the harsh working conditions during loading make finding suitable cement loading workers increasingly difficult.

[0003] Currently, various types of automatic palletizing machines have appeared in the domestic cement market, specifically for the automatic loading of bagged cement. This makes the existing cement loading process unattended, replacing manual palletizing operations inside the truck, avoiding occupational diseases such as pneumoconiosis among workers, and transforming manual labor in harsh environments into automated machine operations. This plays a key role in improving working conditions for enterprises, reducing individual physical labor, and increasing efficiency through workforce reduction.

[0004] To achieve automated cement loading, a receiving and stacking device is required to receive cement bags from the conveyor belt and automatically stack them into the truck bed. Existing receiving and stacking devices are structurally complex, their connection to the conveyor belt is not smooth enough, they easily obstruct the flow of cement bags, and their stacking speed is limited, thus affecting the efficiency of automated loading.

[0043] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0044] To more clearly illustrate the receiving and stacking device of the present invention, the structure and working process of the automatic loading equipment are first introduced, and then the receiving and stacking device is described in detail through Examples 1-2.

[0045] Automated loading equipment such as Figure 1 As shown, the system includes a frame 1, which serves as a support platform. The frame 1 is equipped with major components such as a horizontal conveyor belt 3, an inclined conveyor belt 4, a sliding table device 5, a folding swing arm 6, a hoisting device 7, and a receiving and stacking device 8. An auxiliary platform 2 adjacent to the frame 1 is available for maintenance personnel.

[0046] The hoisting device 7 can drive the receiving and stacking device 8 to rise and fall, and the sliding table device 5 can drive the receiving and stacking device 8 to move back and forth. The back and forth direction is distributed along the length of the frame 1.

[0047] Goods are conveyed from the horizontal conveyor belt 3 to the inclined conveyor belt 4, and then from the inclined conveyor belt 4 to the receiving and stacking device 8. The cargo vehicle is parked below the frame 1, and the goods are stacked into the vehicle compartment by the receiving and stacking device 8.

[0048] Example 1

[0049] like Figure 2 , Figure 4 , Figure 5 , Figure 7The illustration shows Embodiment 1 of the present invention. In this embodiment, a receiving and stacking device 8 for an automated loading equipment is provided, including a main frame 8-1, a buffer slide 8-2, a sorting device 8-3, a receiving hopper device, and a stacking hopper device. The buffer slide 8-2 is located in the middle of the main frame 8-1, with an inclined conveyor belt 4 connected to the upper part and the sorting device 8-3 connected to the lower part. The receiving hopper device includes two sets, respectively located on the left and right sides of the sorting device 8-3. The stacking hopper device also includes two sets, respectively located below the receiving hopper device. Goods fall from the inclined conveyor belt 4 into the buffer slide 8-2, are distributed to the left and right by the sorting device 8-3 into the receiving hopper device, fall from the receiving hopper device into the stacking hopper device, and finally fall from the stacking hopper device into the vehicle.

[0050] like Figure 2 As shown, a second receiving hopper device 8-5 and a second stacking hopper device 8-7 are provided on the left side of the main frame 8-1, and a first receiving hopper device 8-4 and a first stacking hopper device 8-7 are provided on the right side.

[0051] like Figure 6 As shown, the buffer slide 8-2 includes an inclined slide 8-2-1 and a horizontal slide 8-2-2. The upper end of the inclined slide 8-2-1 is hinged to the inclined conveyor belt 4, and the lower end of the inclined slide 8-2-1 is smoothly connected to the horizontal slide 8-2-2.

[0052] Specifically, the lower end of the inclined slide 8-2-1 can be designed as an arc transition section to connect with the horizontal slide 8-2-2. This design allows the goods to fall more smoothly.

[0053] The upper end of the inclined slide 8-2-1 is hinged to the inclined conveyor belt 4 because the receiving and stacking device 8 needs to rotate relative to the inclined conveyor belt 4 during rising and falling, so the connection point with the inclined conveyor belt 4 must be rotatable.

[0054] like Figure 6 As shown, guardrails are installed on both sides of the inclined slide 8-2-1 to prevent goods from falling accidentally.

[0055] The horizontal slide 8-2-2 has outlets on both the left and right sides, and a baffle is installed on the front side. The sorting device 8-3 is located above the horizontal slide 8-2-2. The baffle can block and stop incoming goods. When the sorting device 8-3 distributes goods to the left and right sides, it pushes the goods out from the outlets on both sides of the horizontal slide 8-2-2.

[0056] The inclined slide 8-2-1 and the horizontal slide 8-2-2 can be made from a single piece of steel plate by stamping, or they can be made separately and then welded together.

[0057] like Figure 4 , Figure 5As shown, the sorting device 8-3 includes a push plate 8-3-7 and a first transverse drive device. The first transverse drive device includes a motor 8-3-1, a reducer, a lead screw 8-3-4, and a nut 8-3-3. The motor 8-3-1 is connected to the reducer, and the reducer is connected to the lead screw 8-3-4. The top of the main frame 8-1 is provided with two bearing seats to mount the lead screw 8-3-4, namely the first bearing seat 8-3-2 and the second bearing seat 8-3-9.

[0058] The top of the main frame 8-1 is provided with two guide rails 8-3-8, a slider 8-3-6 is provided on the guide rails 8-3-8, a slide block 8-3-5 is provided on the slider 8-3-6, a nut 8-3-3 is fixed on the slide block 8-3-5, a lead screw 8-3-4 passes through the nut 8-3-3, and a push plate 8-3-7 is fixed on the lower side of the slide block 8-3-5. When the lead screw 8-3-4 rotates, it drives the nut 8-3-3 to move axially, thereby driving the push plate 8-3-7 to move horizontally left and right.

[0059] like Figure 4 As shown, the slide block 8-3-5 is I-shaped with wider ends. Each end can be supported by two or more sliders 8-3-6 to achieve stable support.

[0060] like Figure 7 As shown, the rear side of the main frame 8-1 is provided with a second lateral movement drive device 8-8 and a third lateral movement drive device 8-9, which drive the two sets of stacking bucket devices to move horizontally left and right respectively; by adjusting the lateral position of the two sets of stacking bucket devices, the goods can be accurately stacked in the vehicle compartment.

[0061] Guide rails 8-10 are provided on the front and rear sides of the main frame 8-1. The stacking bin device is mounted on the guide rails 8-10 and moves horizontally along the guide rails 8-10 under the drive of the second transverse drive device 8-8 and the third transverse drive device 8-9.

[0062] The guide rails 8-10 consist of four rails in total. Two rails are set on the front and rear sides of the main frame 8-1, and they are arranged vertically. The first cargo bin device 8-6 is mounted on the two lower guide rails 8-10, and the second cargo bin device 8-7 is mounted on the two upper guide rails 8-10.

[0063] Slider blocks need to be installed on guide rails 8-10 to support the stacking bin device. Two or more sliders can be installed on each side to provide stable support.

[0064] like Figure 7As shown, both the second lateral movement drive device 8-8 and the third lateral movement drive device 8-9 include a motor, a reducer, a lead screw, and a nut. The motor is connected to the reducer, and the reducer is connected to the lead screw. Two bearing seats are provided on the rear side of the main frame 8-1 to mount the lead screw. The nut is connected to the stacking bin device through a connecting plate. When the lead screw rotates, it drives the nut to move axially, thereby driving the stacking bin device to move horizontally left and right.

[0065] To facilitate the installation of the second lateral movement drive unit 8-8 and the third lateral movement drive unit 8-9, a bracket is specially provided on the rear side of the main frame 8-1, such as... Figure 7 As shown, the second lateral movement drive unit 8-8 and the third lateral movement drive unit 8-9 are located below the inclined slide rail 8-2-1 after installation. This design can reduce the space occupied by the second lateral movement drive unit 8-8 and the third lateral movement drive unit 8-9.

[0066] Alternatively, the second lateral movement drive device 8-8 and the third lateral movement drive device 8-9 can be set on the front side of the main frame 8-1, but this will increase the width of the receiving and stacking device 8.

[0067] When the receiving and stacking device 8 is working, the buffer slide 8-2 receives the goods conveyed from the inclined conveyor belt 4 and is distributed by the sorting device 8-3 to the first receiving hopper device 8-4 and the second receiving hopper device 8-5 respectively. Under control, the goods in the first receiving hopper device 8-4 fall down to the first stacking hopper device 8-6, and the goods in the second receiving hopper device 8-5 fall down to the second stacking hopper device 8-7.

[0068] Under controlled conditions, the goods in the first stacking bin device 8-6 and the second stacking bin device 8-7 fall into the cargo compartment of the freight vehicle. The first stacking bin device 8-6 and the second stacking bin device 8-7 move left and right within the main frame 8-1 to adjust the stacking position of the goods in the cargo compartment.

[0069] The receiving and stacking device 8 can significantly improve the receiving and stacking speed by continuously distributing goods left and right, thereby improving the efficiency of automatic loading of goods.

[0070] The structures of the aforementioned first receiving hopper device 8-4, second receiving hopper device 8-5, first stacking hopper device 8-6, and second stacking hopper device 8-7 are similar. The second stacking hopper device 8-7 will be used as an example for illustration below.

[0071] like Figure 9 , Figure 10 , Figure 11As shown, the second stacking hopper device 8-7 includes a frame 8-7-1. The top of the frame 8-7-1 is provided with an inlet, and the bottom of the frame 8-7-1 is provided with an outlet. The outlet is provided with two opposing flaps 8-7-2. The front end of the frame 8-7-1 is provided with a driving device. The driving device is connected to the flaps 8-7-2 through a linkage mechanism. The driving device drives the flaps 8-7-2 to close relative to each other. The goods in the second stacking hopper device 8-7 are supported by the flaps 8-7-2. The driving device drives the flaps 8-7-2 to open relative to each other, and the goods fall from the outlet.

[0072] The frame 8-7-1 serves as the mounting base for other components and also provides protection on all sides to prevent goods from accidentally falling out of the second-yard cargo bin device 8-7.

[0073] The outer edge of the flap 8-7-2 is connected to the frame 8-7-1 via several hinges 8-7-3, preferably three or more. The hinges 8-7-3 are hinge-type hinges, allowing the flap 8-7-2 to rotate relative to the frame 8-7-1.

[0074] like Figure 12 As shown, a suitable gap is left between the two flip plates 8-7-2 so that the two flip plates 8-7-2 will not interfere when they are flipped.

[0075] The linkage mechanism includes a main link 8-7-6 and two secondary links 8-7-7. The main link 8-7-6 is U-shaped with the opening facing upwards, and the drive device is connected to the middle of the main link 8-7-6.

[0076] The upper end of the secondary connecting rod 8-7-7 is hinged to the main connecting rod 8-7-6, and the lower end of the secondary connecting rod 8-7-7 is hinged to the end of the flap 8-7-2.

[0077] When the drive device drives the main connecting rod 8-7-6 to move downward, the main connecting rod 8-7-6 drives the secondary connecting rod 8-7-7, and the secondary connecting rod 8-7-7 drives the two flaps 8-7-2 to open relative to each other; when the drive device drives the main connecting rod 8-7-6 to move upward, the main connecting rod 8-7-6 drives the secondary connecting rod 8-7-7, and the secondary connecting rod 8-7-7 drives the two flaps 8-7-2 to close relative to each other.

[0078] For ease of connection, the inner sides of the two arms of the main connecting rod 8-7-6 are provided with protrusions, and the upper end of the secondary connecting rod 8-7-7 is hinged to the protrusions.

[0079] Two parallel guide rails 8-7-8 are provided on the front end plate 8-7-4 of the frame 8-7-1. A slider 8-7-9 is provided on the guide rail 8-7-8. The two ends of the main connecting rod 8-7-6 are respectively connected and fixed to the slider 8-7-9. When the driving device drives the main connecting rod 8-7-6 to move, it is guided by the guide rail 8-7-8.

[0080] The aforementioned guiding mechanism ensures that the main connecting rod 8-7-6 does not wobble, and that the opening and closing of the two flaps 8-7-2 proceeds synchronously and smoothly.

[0081] The slider 8-7-9 is engaged with the guide rail 8-7-8 and will not detach from the guide rail 8-7-8 (except for the two ends, which can detach from the two ends of the guide rail 8-7-8).

[0082] In this embodiment, the frame 8-7-1 is rectangular, and the flap 8-7-2 is rectangular. The frame 8-7-1 can be made of welded steel plates, and the flap 8-7-2 can be made of steel plates.

[0083] The drive unit specifically uses cylinder 8-7-5, but an electric cylinder can also be used. The piston rod end of cylinder 8-7-5 is hinged to the middle of the main connecting rod 8-7-6.

[0084] Cylinder 8-7-5 is a double-acting cylinder; it can perform work by extending the piston rod downwards and retracting it upwards. When the two flaps 8-7-2 are closed relative to each other to support the goods, cylinder 8-7-5 needs to provide an upward pulling force to prevent the two flaps 8-7-2 from opening relative to each other, thereby supporting the goods.

[0085] The upper and lower ends of the outer cylinder of cylinder 8-7-5 are fixed to the front end plate 8-7-4.

[0086] The first-stage cargo bin device 8-6 also adopts the same structural setup as described above, and its working process is also the same.

[0087] When the first stacking bin device 8-6 and the second stacking bin device 8-7 are installed in the receiving and stacking device 8, they can be connected to the front and rear end plates of the first stacking bin device 8-6 and the second stacking bin device 8-7 via connecting plates, such as... Figure 3 As shown.

[0088] The receiving hopper device and the stacking hopper device in this embodiment have simple structures, stable and reliable operation, and ensure the efficiency of automatic loading of goods.

[0089] An inlet is provided on the side of the frame, thus forming a first receiving hopper device 8-4 and a second receiving hopper device 8-5. The sorting device 8-3 can push goods into the first receiving hopper device 8-4 and the second receiving hopper device 8-5.

[0090] The structure of the first receiving hopper device 8-4 is as follows: Figure 8 As shown, the right side panel of the frame is lower, thus forming the inlet, while the outlet is still located at the bottom of the frame.

[0091] The top of the frame can be closed, thereby increasing the structural strength of the frame, and the frame top is used to fix the receiving and stacking device 8.

[0092] Example 2

[0093] The difference between Example 2 and Example 1 is that the driving device of the receiving hopper device and the stacking hopper device includes two sets of parallel cylinders, which simultaneously drive the flap.

[0094] Using two sets of parallel cylinders to drive the flap simultaneously can increase the driving force and carry heavier goods.

[0095] In this embodiment, the other structures of the receiving and stacking device 8 are the same as those in Embodiment 1, and will not be described again here.

[0096] The above are merely specific embodiments of the present invention. Under the teachings of the present invention, those skilled in the art can make other improvements or modifications based on the above embodiments. Those skilled in the art should understand that the above specific description is only to better explain the purpose of the present invention, and the scope of protection of the present invention should be determined by the scope of the claims.
