Description

Technical Field

[0001] This utility model relates to the field of cargo transportation technology, specifically a corner chain roller conveyor. Background Technology

[0002] In the field of freight transportation, chain roller conveyors are common conveying equipment, widely used in logistics sorting, production line transfer, and other scenarios. Traditional chain conveyor lines are mostly linear in layout. When it is necessary to change the conveying direction, the following two methods are usually used: one is to transfer the goods to another conveyor line by means of robotic arms or transfer devices. This method is complex, costly, and inefficient; the other is to use curved chain tracks to achieve planar turning. However, this is limited by chain tension and turning radius, which can easily lead to goods deviation or jamming, especially with poor adaptability to heavy or large-sized goods.

[0003] Existing chain conveyor lines typically use a straight-line transport method, which cannot achieve vertical corner transport. Alternatively, some chain transmissions may use a combination of multiple independently driven chain lines to achieve turning, but this results in complex structures, poor synchronization, and an inability to meet the compact layout requirements in space-constrained scenarios. Therefore, a corner chain roller conveyor is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a corner chain roller conveyor, which has the advantages of vertical corner transportation, streamlined equipment structure, and efficient reverse transfer of goods. It solves the problems of difficult vertical corner transportation, complex corner transportation structure, poor synchronization, and limited space.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a corner chain roller conveyor, including a base frame, three chain conveyor frames are fixedly installed on the top of the base frame, and the three chain conveyor frames are respectively located on the left and right sides and the middle of the base frame. A lifting frame is provided on the top of the base frame and between the three chain conveyor frames. A fixing frame is fixedly installed inside the base frame and at the bottom of the lifting frame. The fixing frame is provided with three chain drive boxes. Three sets of chain drive structures for chain cargo transmission are provided inside the three chain drive boxes and the three chain conveyor frames.

[0006] Chain bogies are fixedly installed on the narrow inner walls on both sides of the three chain drive boxes. Two chain limiting grooves are opened on the arc surface of each chain bogie. Four slide bars are fixedly installed on the front and rear sides of the top of the base frame. Sliding blocks that are in clearance fit with the slide bars are slidably provided on the front and back of the lifting frame. Clearance holes are also opened on the front and back of the lifting frame. The inside of the lifting frame is provided with a roller lifting structure for driving the lifting frame to rise and fall.

[0007] Furthermore, a clearance groove is provided in the middle of the lifting frame, which is used to allow the lifting frame to avoid the chain conveyor frame at the middle of the top of the base frame during the lifting process.

[0008] Furthermore, the chain drive structure includes a chain drive motor, a transmission chain, a first transmission gear disc, three conveying chains, and a lead screw. The chain drive motor is fixedly mounted on the side of the fixed frame. The two ends of the lead screw are disposed between the three chain transmission boxes and rotatably connected to the chain transmission boxes on both sides via bearings. The first transmission gear disc is fixedly mounted on the outer surface of the lead screw. The transmission chains are respectively sleeved between the output end of the chain drive motor and the outer surface of the first transmission gear disc. The three chain transmission boxes are each fitted with a second transmission gear disc located inside the outer surface of the lead screw. The three chain conveying frames are each provided with several chain drive shafts. The three conveying chains are respectively sleeved inside the several chain drive shafts inside the three chain conveying frames and inside the second transmission gear discs inside the three chain transmission boxes.

[0009] Furthermore, each of the three chain drive boxes has a through hole on its side for the lead screw to pass through. When the conveyor chain winds around the second transmission gear, the conveyor chain also needs to be embedded into the chain limiting groove on the chain bogie for turning.

[0010] Furthermore, the roller lifting structure includes a servo motor, multiple drive rollers, a drive shaft, a fixed base, an eccentric wheel, and an eccentric wheel pressing block. The fixed base is fixedly installed on the top of the base frame. The multiple drive rollers are rotatably arranged in the middle of the lifting frame via bearings. The servo motor is fixedly installed on the top of the base frame and located on the other side of the fixed base. Two clearance holes are provided at both ends of the drive shaft between the output end of the servo motor and the fixed base. The eccentric wheel is fixedly sleeved on the outer surface of the drive shaft. The eccentric wheel pressing block is fixedly arranged on the inner wall of one side of the lifting frame.

[0011] Furthermore, when the eccentric wheel rotates and extrudes the eccentric wheel extrusion block, the lifting frame is restricted from lifting and lowering by the action of the slide bar and the slider.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] 1. This corner chain roller conveyor allows for seamless switching between horizontal conveying and vertical lifting of goods through the coordinated operation of the lifting frame and the chain conveyor frame. The chain limit groove on the chain steering frame ensures stable operation of the conveyor chain during turning, avoiding chain derailment or goods slippage problems caused by traditional planar turning.

[0014] 2. This corner chain roller conveyor integrates the lifting mechanism and the conveyor line into one unit by adopting a layout of embedded fixed frame and lifting frame in the base frame, thereby reducing the equipment's footprint.

[0015] 3. This corner chain roller conveyor features a roller lifting structure with mechanical limits from eccentric wheels and slide bars, ensuring smooth and undulating lifting. It is suitable for transporting precision goods. The three sets of synchronously driven chain drive structures are linked by lead screws, avoiding synchronization errors caused by multi-motor control and improving conveying efficiency.

[0016] 4. This corner chain roller conveyor can flexibly configure the number and height of the chain conveyor frames to meet the conveying needs of different scenarios, such as factory production lines and automated warehouses. It has good compatibility with heavy or irregularly shaped goods, and the design of the chain limit groove and drive roller effectively prevents goods from shifting. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-6 This embodiment of a corner chain roller conveyor includes a base frame 1, characterized in that: three chain conveyor frames 7 are fixedly installed on the top of the base frame 1, and the positions of the three chain conveyor frames 7 are respectively set on the left and right sides and the middle of the base frame 1; a lifting frame 3 is set on the top of the base frame 1 and between the three chain conveyor frames 7; a fixed frame 2 is fixedly installed inside the base frame 1 and at the bottom of the lifting frame 3; the fixed frame 2 is provided with three chain drive boxes 4; and three sets of chain drive structures 8 for chain cargo transmission are set inside the three chain drive boxes 4 and the three chain conveyor frames 7.

[0026] Chain guide frames 9 are fixedly installed on the narrow inner walls of the three chain drive boxes 4. Two chain limit grooves 10 are opened on the arc surface of the chain guide frames 9. Four slide bars 11 are fixedly installed on the front and rear sides of the top of the base frame 1. Sliding blocks 12 that are in clearance fit with the slide bars 11 are slidably set on the front and back of the lifting frame 3. The front and back of the lifting frame 3 are also provided with clearance holes 13. The inside of the lifting frame 3 is provided with a roller lifting structure 5 for driving the lifting frame 3 to rise and fall.

[0027] The lifting frame 3 has a clearance groove in the middle, which is used to allow the lifting frame 3 to avoid the chain conveyor frame 7 at the top middle of the base frame 1 during the lifting process.

[0028] Example 1:

[0029] like Figures 1 to 6 As shown, this embodiment provides a corner chain roller conveyor, including a base frame 1, a fixed frame 2, a lifting frame 3, a chain drive box 4, a roller lifting structure 5, a chain conveyor frame 7, and a chain drive structure 8. The base frame 1 serves as the fundamental support for the entire equipment, with three chain conveyor frames 7 fixedly installed on its top, located on the left, right, and middle sides of the base frame 1, respectively. A lifting frame 3 is positioned between the three chain conveyor frames 7 on the top of the base frame 1. A fixed frame 2 is fixedly installed inside the base frame 1 at the bottom of the lifting frame 3, and three chain drive boxes 4 are mounted on the fixed frame 2. Three sets of chain drive structures 8 are installed inside the three chain drive boxes 4 and the three chain conveyor frames 7 to drive the chains and achieve the transfer of goods.

[0030] In this embodiment, the chain drive structure 8 includes a chain drive motor 81, a transmission chain 82, a first transmission gear 83, three conveying chains 84, and a lead screw 85. The chain drive motor 81 is fixedly mounted on the side of the fixed frame 2. The two ends of the lead screw 85 are located between the three chain transmission boxes 4 and are rotatably connected to the chain transmission boxes 4 on both sides through bearings. The first transmission gear 83 is fixedly mounted on the outer surface of the lead screw 85. The transmission chains 82 are respectively sleeved between the output end of the chain drive motor 81 and the outer surface of the first transmission gear 83. The three chain transmission boxes 4 are each equipped with a second transmission gear 86 located on the outer surface of the lead screw 85. The three chain conveying frames 7 are each equipped with a plurality of chain drive shafts 87. The three conveying chains 84 are respectively sleeved inside the plurality of chain drive shafts 87 inside the three chain conveying frames 7 and inside the second transmission gear 86 inside the three chain transmission boxes 4.

[0031] The three chain drive boxes 4 are provided with through holes on their sides for the lead screw 85 to pass through. When the conveying chain 84 is wound around the transmission gear 86, the conveying chain 84 needs to be embedded into the chain limiting groove 10 on the chain bogie 9 for turning.

[0032] Specifically, by activating the chain drive motor 81 on the side of the fixed frame 2, the lead screw 85 is rotatably connected to the chain transmission boxes 4 on both sides via bearings, and the first transmission gear 83 is fixed on the lead screw 85. The transmission chain 82 is sleeved between the output end of the chain drive motor 81 and the first transmission gear 83 to realize power transmission. When the lead screw 85 rotates, it drives the second transmission gear 86 to rotate, thereby driving the conveyor chain 84 to move on the chain drive shaft 87 inside the chain conveyor frame 7 to realize the conveying of goods. The chain limiting groove 10 on the chain bogie 9 is used to guide the conveyor chain 84 to turn, ensuring that the chain does not derail during the turning process.

[0033] In this embodiment, the roller lifting structure 5 includes a servo motor 51, multiple transmission rollers 52, a transmission shaft 53, a fixed seat 54, an eccentric wheel 55, and an eccentric wheel pressing block 56. The fixed seat 54 is fixedly installed on the top of the base frame 1. The multiple transmission rollers 52 are rotatably arranged in the middle of the lifting frame 3 through bearings. The servo motor 51 is fixedly installed on the top of the base frame 1 and located on the other side of the fixed seat 54. Two clearance holes are provided at both ends of the transmission shaft 53 between the output end of the servo motor 51 and the fixed seat 54. The eccentric wheel 55 is fixedly sleeved on the outer surface of the transmission shaft 53. The eccentric wheel pressing block 56 is fixedly arranged on the inner wall of one side of the lifting frame 3.

[0034] When the eccentric wheel 55 rotates and squeezes the eccentric wheel extrusion block 56, the lifting frame 3 is restricted from lifting and lowering under the action of the slide bar 11 and the slider 12.

[0035] Specifically, the servo motor 51 drives the transmission shaft 53 to rotate, which in turn drives the eccentric wheel 55 to rotate. When the eccentric wheel 55 rotates to the point where the protruding part contacts the eccentric wheel pressing block 56, the pressing block pushes the lifting frame 3 upward; when the eccentric wheel 55 continues to rotate to the concave part, the lifting frame 3 descends under the action of gravity. The cooperation of the slide bar 11 and the slider 12 restricts the horizontal displacement of the lifting frame 3, ensuring that it only performs vertical lifting movements. The clearance groove design of the lifting frame 3 allows it to avoid interference with the intermediate chain conveyor frame 7 during the lifting process.

[0036] The working principle of the above embodiments is as follows:

[0037] The first step is to transport the goods in a straight line via the conveyor chain 84 on the chain conveyor frame 7.

[0038] The second step is that when a turn is required, the chain drive structure 8 drives the conveyor chain 84 into the chain limiting groove 10 of the chain bogie 9 to complete the turn.

[0039] Third, the lifting frame 3 uses the lifting movement of the roller lifting structure 5 to realize the transfer of goods between different height conveyor lines.

[0040] Fourthly, the cooperation between slide bar 11 and slider 12 ensures the stability of the movement of the lifting frame 3, and the design of eccentric wheel 55 and eccentric wheel pressing block 56 realizes precise control of lifting.
