Description

Technical Field

[0001] This application proposes a novel rotating chain machine, which is activated by fire alarm linkage or manual control to rotate itself, thereby facilitating the closure of the conveying space for fireproof rolling shutter doors, and belongs to the field of logistics and warehousing. Background Technology

[0002] In the existing logistics and warehousing field, conveyor lines used in express delivery, e-commerce, and manufacturing enterprise warehousing and distribution centers are typically designed with different functional zones. Current fire safety laws and regulations in my country clearly stipulate the building area for fire-prevention zones in factory buildings. Fire-prevention zones must be separated by firewalls, and connecting spaces must also be fire-separated, using measures such as fire-resistant roller shutters or fire-resistant water curtains to isolate fire.

[0003] When a fire occurs and fire isolation is required, the fire-resistant roller shutter door initiates its closing procedure. However, the conveyor system beneath the shutter door often interferes with its closure, preventing complete fire isolation. Manually moving this conveyor system during a fire significantly increases evacuation time and poses safety hazards. Currently designed and used tilting chain conveyors typically have a tilting function and allow for a large clearance when considering the opening and closing of fire doors to ensure their normal raising and lowering.

[0004] The existing disclosed flipping chain machine has the following main disadvantages: 1. The flipping drive motor adopts an external installation structure, which significantly increases the requirements for installation space; 2. The transmission chain does not have a tensioning device, which brings additional maintenance costs for long-term use of the equipment; 3. The flipping part does not have a guide positioning when it is flattened and returned to its original position, which causes the docking deviation with the original docking conveyor line and affects the conveying of the equipment.

[0005] In view of the above, this patent application is hereby filed. Summary of the Invention

[0006] The purpose of this application for a chain-reversing machine is to solve the problems existing in the prior art. It significantly reduces the installation space and maintenance costs of the drive components, while simultaneously improving the stability of the equipment and the smoothness of material flow.

[0007] To achieve the above design objectives, the tilting chain machine includes a fixed frame assembly, and a tilting frame assembly driven by a tilting drive assembly is provided on one side of the fixed frame assembly. The tilting frame assembly can reciprocate around the axial direction of its connection with the fixed frame assembly. Two sets of end-to-end connected conveyor chain assemblies, driven by a conveyor drive assembly, are provided on the fixed frame assembly and the tilting frame assembly. The fixed frame assembly is supported and vertically supported by fixed support leg assemblies, and during cargo transport, the tilting frame assembly is supported and vertically supported by tilting guide support leg assemblies.

[0009] Furthermore, the conveying drive assembly includes a conveying drive motor and a conveying transmission shaft mounted on one side of the fixed frame weldment.

[0029] Example 1, such as Figures 1 to 5 As shown, a novel flipping chain machine includes a fixed frame assembly 1. A flipping frame assembly 2, driven by a flipping drive assembly 4, is provided on one side of the fixed frame assembly 1. The flipping frame assembly 2 can reciprocate around the axial direction of its connection with the fixed frame assembly 1. Two sets of conveyor chain assemblies, connected end-to-end and driven by a conveyor drive assembly 3, are provided on the fixed frame assembly 1 and the flipping frame assembly 2. The fixed frame assembly 1 is supported and vertically supported by a fixed support leg assembly 5. During the transport of goods, the flipping frame assembly 2 is supported and vertically supported by a flipping guide support leg assembly 6.

[0030] The conveyor drive assembly 3 can be installed on one side of the fixed frame assembly 1 to reduce the weight of the tilting frame assembly 2 when it is tilted; the fixed support leg assembly 5 is installed on the ground and is fastened to the fixed frame assembly 1 by an array of bolts.

[0031] The fixed frame assembly 1 has a fixed frame weldment 1.2. A set of pallet guide assemblies 1.5 and at least one set of photoelectric detection assemblies 1.6 are respectively arranged on both sides of the top of the fixed frame weldment 1.2. An end sprocket assembly 1.1 is arranged along the conveying direction. A conveying chain 1.3 running in the chain guide rail 1.4 is driven and connected between the end sprocket assemblies 1.1 at both ends. The goods conveying operation is realized by the rotation of the conveying chain 1.3. The photoelectric detection assembly 1.6 is used to detect whether goods are transferred to the conveying chain 1.3.

[0032] The tilting frame assembly 2 includes a tilting frame weldment 2.1. An array of transition sprockets 2.3 and end sprockets 2.6, as well as at least one set of tilting sensor assemblies 2.7, are provided on the top of the tilting frame weldment 2.1. An auxiliary conveying chain 2.2 runs in a closed loop between the end sprockets 2.6. The transition sprockets 2.3 cooperate with the end sprocket assembly 1.1 to realize the rotation and closure of the conveying chain 1.3. A transition chain 2.4 runs in a closed loop between the transition sprockets 2.3. The transition chain 2.4 is used to transmit the conveying power from the fixed frame assembly 1 to the tilting frame assembly 2.

[0033] A chain tensioning assembly 2.5 is provided at the running end of the transition chain 2.4 and on the side of the flip frame weldment 2.1 to enable rapid tension adjustment of the transition chain 2.4, reduce manual maintenance costs and equipment operating costs.

[0034] The chain tensioning assembly 2.5 includes a mounting plate 2.5.1, a positioning mounting block 2.5.2, and an adjusting mounting block 2.5.3. The mounting plate 2.5.1 is connected to the outside of the tilting frame weldment 2.1 by an array of bolts 2.5.4. Each set of bolts 2.5.4 is inserted through and into the adjusting groove 2.5.5 provided on the mounting plate 2.5.1. The positioning mounting block 2.5.2 is fastened to the tilting frame weldment 2.1, and the adjusting mounting block 2.5.3 is fastened to the mounting plate 2.5.1. The adjusting bolt 2.5.6 passes through the positioning mounting block 2.5.2 and the adjusting mounting block 2.5.3 in sequence, and the end of the adjusting bolt 2.5.6 is fixed to the shaft end of the drive shaft of the winding transition chain 2.4. When adjusting the tension of the transition chain 2.4, first loosen and remove bolt 2.5.4 to release the adjusting mounting block 2.5.3 and mounting plate 2.5.1. Then, manually rotate the adjusting bolt 2.5.6. The adjusting bolt 2.5.6 moves back and forth between the positioning mounting block 2.5.2 and the adjusting mounting block 2.5.3, thereby moving the end of the drive shaft winding the transition chain 2.4, thus adjusting the tension of the transition chain 2.4. After adjustment, reinstall bolt 2.5.4 and fasten mounting plate 2.5.1 on the outside of the tilting frame weldment 2.1.

[0035] The conveying drive assembly 3 includes a conveying drive motor 3.1 and a conveying transmission shaft 3.5 mounted on one side of the fixed frame weldment 1.2. The output end of the conveying drive motor 3.1 is fitted with a conveying drive sprocket 3.2. A conveying transmission sprocket 3.3 and a conveying sprocket meshing with the conveying chain 1.3 are fitted on the conveying transmission shaft 3.5. A conveying transmission chain 3.4 that drives the conveying transmission shaft 3.5 to rotate is running in a closed loop between the conveying drive sprocket 3.2 and the conveying transmission sprocket 3.3. Under the drive of the conveying drive motor 3.1, the conveying transmission shaft 3.5 rotates while transmitting conveying power to the conveying chain 1.3.

[0036] The flipping drive assembly 4 is provided on the inner side of the end where the flipping frame assembly 2 connects with the fixed frame assembly 1. Since the flipping drive assembly 4 is located entirely inside the flipping frame assembly 2 and does not occupy the space outside the frame assembly, the flipping drive assembly 4 is more compact, and therefore the overall size and space occupied by the flipping chain machine are smaller. Specifically, the tilting drive assembly 4 includes a tilting shaft 4.5, a tilting transmission shaft 4.4, and a tilting drive motor 4.1, all fixedly connected to the tilting frame welded part 2.1. A tilting drive sprocket 4.2 is fitted onto the output end of the tilting drive motor 4.1, and a tilting transmission sprocket 4.3 is fitted onto the tilting transmission shaft 4.4. A chain runs in a closed loop between the tilting drive sprocket 4.2 and the tilting transmission sprocket 4.3 to transmit the power output from the tilting drive motor 4.1 to the tilting transmission shaft 4.4. A set of sprockets meshing with a tilting transmission chain 4.6 is fitted onto both ends of the tilting transmission shaft 4.4. The tilting transmission chain 4.6 winds in a closed loop between the tilting shaft 4.5 and the tilting transmission shaft 4.4 to ultimately transmit the power to the tilting shaft 4.5, thereby realizing the overall reciprocating tilting of the tilting frame assembly 2. A tilting sprocket guard 4.7 is fitted onto the outside of the tilting shaft 4.5 to prevent personnel injury and to prevent foreign objects from entering the interior of the tilting drive assembly 4 and causing equipment damage.

[0037] Accordingly, a flip sensing sensor assembly 2.7 can be provided at the end of the flip shaft 4.5 to detect the overall flip position and angle of the flip frame assembly 2.

[0038] During installation, the conveyor chain 1.3 on the fixed frame assembly 1 passes through the transition sprocket 2.3 fitted on the flip shaft 4.5 and returns to the fixed frame assembly 1 to form a closed chain; the transition chain 2.4 passes through the transition sprocket 2.3 fitted on the flip shaft 4.5 and forms a closed chain with the end sprocket 2.6 on the flip frame assembly 2. The end sprocket 2.6 of the flip frame assembly 2 can be tensioned by the chain tensioning assembly 2.5; the conveyor chain 2.2 on the flip frame assembly 2 passes through the end sprocket 2.3 and returns to the flip frame assembly 2 to form a closed chain. Through the above three closed chains, the synchronous conveying of the chains on the fixed frame assembly 1 and the flip frame assembly 2 is achieved.

[0039] The fixed support leg assembly 5 includes a fixed support leg weldment 5.1, and an adjustable foot 5.2 is provided at the bottom of the fixed support leg weldment 5.1 to adjust the installation height of the assembly.

[0040] The flip-up guide leg assembly 6 includes a flip-up leg weldment 6.1. A flip-up adjustment foot 6.2 is provided at the bottom of the flip-up leg weldment 6.1 to adjust the installation height of the assembly. A set of guide plates 6.3 are symmetrically arranged on both sides of the top of the flip-up leg weldment 6.1. The guide plates 6.3 have outward and upward inclined bends, which can provide guidance when the flip-up frame assembly 2 is flipped back to its original position.

[0041] When there is no fire, the roller shutter door is in the rolled-up state, the tilting frame assembly 2 is in a horizontal state, and it is connected to the front fixed frame assembly 1, with the tail end resting above the tilting guide leg assembly 6. The drive motor in the conveyor drive assembly 3 rotates normally, driving the chain conveyor on the fixed frame assembly 1, and then transmitting the power to the chain of the tilting frame assembly 2 through the transition chain 2.4, thereby realizing the normal conveying of the entire tilting chain machine and ensuring the smooth flow of the conveyor line.

[0042] When the rotating chain conveyor needs to descend in case of fire, the motor in the conveyor drive assembly 3 stops and locks. The conveyor chains in the fixed frame assembly 1 and the rotating frame assembly 2 stop conveying. The drive motor in the rotating drive assembly drives the rotating shaft 3 to rotate, causing the rotating frame to rotate upward around the rotating shaft 3. After the sensor assembly at the end of the rotating shaft 3 detects that the rotating frame has reached its position, the rotating drive motor stops. At this time, the rotating chain conveyor makes way for the fireproof roller shutter door, which can then be lowered smoothly to achieve fire isolation.

[0043] After the fire is extinguished, the fireproof roller shutter door rises, and the drive motor in the tilting drive assembly 3 reverses, driving the tilting frame assembly 2 to tilt downwards around the tilting shaft 4.4 until the tilting reactor sensing sensor assembly 2.7 senses that the tilting frame assembly has returned to its position, at which point the drive motor stops. At this time, the tilting frame 3, under the action of the guide leg assembly 5, accurately returns to a horizontal state and can accurately connect with the front and rear conveyor lines without misalignment.

[0044] As described above, the embodiments given in conjunction with the accompanying drawings are merely preferred solutions for achieving the objectives of this invention. Those skilled in the art can draw inspiration from this and directly derive other alternative structures that conform to the design concept of this invention. Other structural features derived therefrom should also fall within the scope of the solutions described in this invention.
