Description

Technical Field

[0001] This invention relates to the field of conveyor system technology, and more specifically to a conveyor line capable of emergency rail breakage. Background Technology

[0002] Currently, conveyor lines on the market need to pass through the doors of various workshops in actual use. Due to fire safety requirements, each workshop door is equipped with a fire door. In the event of a fire, the fire door must be closed to isolate the fire source. However, closing the door will obstruct the conveyor line. Therefore, there is an urgent need to develop a fire emergency device for conveyor lines that will not obstruct the closing of the fire door when it is closed in the event of a fire.

[0003] Chinese Patent Application No. 2020201264506 discloses a transport line with a fireproof disconnection device, including a first transport track and a second transport track for transporting a vehicle. A disconnectable transition transport track is connected between the first and second transport tracks. One end of the transition transport track is hinged to the first transport track. A locking mechanism for fixed connection with the other end of the transition transport track is installed on the second transport track. A locking block for abutting against the upper end of the locking mechanism is provided on the lower side of the other end of the transition transport track. When the locking mechanism extends and is placed inside the lower end face of the locking block, it is fixedly connected to the other end of the transition transport track. When the locking mechanism retracts from below the locking block, the connection between the transition transport track and the second transport track will be disconnected.

[0004] Chinese Patent Application No. CN2018220422315 discloses a disconnectable transition device for a conveyor line. This device is disconnectable and located at the lower position of a fire door. A vehicle drive mechanism is provided in the disconnectable transition section to propel the vehicle forward. The invention includes an upstream conveyor line, a downstream conveyor line, and a transition mechanism. The starting end of the transition mechanism is horizontally rotatable on the upstream conveyor line via a rotating shaft. The end of the transition mechanism can connect to or disconnect from the starting end of the downstream conveyor line depending on the horizontal rotation of the starting end. The transition mechanism includes a sliding ramp, a climbing ramp, and a self-sliding ramp. A locking tongue on the downstream conveyor line cooperates with a positioning groove on the transition mechanism.

[0005] Chinese Patent Application No. CN2018207025696 discloses an emergency disconnection device for double fire doors in a conveyor system. This device is well-suited for the setup of double fire doors, facilitating timely activation in emergencies. The disconnection device maintains smooth operation for extended periods. The device is positioned at the break in the conveyor line of the conveyor system, corresponding to the location of the fire door, to allow for the fire door's descent in an emergency. A support rail is hinged to each end of the break, with one support rail corresponding to one fire door. The two support rails are connected to two driving mechanisms. Under the action of the driving mechanisms, the support rails move around their respective hinge points, causing their outer ends to overlap in the inclined direction, or causing the support rails to move away from the break position.

[0006] Designs similar to the prior art described above can also be found in the following Chinese patent applications: CN2020216019653, CN2020219476082, CN2018207219899, ​​CN2022223821173.

[0007] In existing technologies, the opening is achieved by rotating the guide rail at the fire door and using a carrier drive mechanism, thereby preventing the conveyor line from obstructing the closing of the fire door. However, the solutions in the above-mentioned existing technologies are only applicable to belt conveyors, chain conveyors, roller conveyors, etc., whose transmission mechanisms can be set in sections. However, when dealing with conveyors that use only a whole rack and pinion for transmission, the above solutions are no longer applicable. Summary of the Invention

[0029] As an optional technical solution, the connector is provided with a partition in the center that is adapted to the end face of the rack guide rail and the rack connecting guide rail;

[0030] Both ends of the partition are also equipped with insertion posts that are compatible with the insertion holes on the end faces of the rack and pinion guide rail and the rack and pinion connecting guide rail.

[0031] As an optional technical solution, there is a gap between the two ends of the carrier connecting guide rail and the carrier guide rail, and a transition mechanism is provided at this gap.

[0032] Optionally, the transition mechanism is a transition joint; the transition joints at both ends of the vehicle connecting rail are respectively connected to the vehicle rail or the vehicle connecting rail.

[0033] Optionally, both ends of the carrier connecting guide rail and the end of the carrier guide rail are provided with constriction grooves;

[0034] The transition mechanism includes a third drive mechanism mounted on the carrier guide rail, which is used to drive the connecting block to slide along the constriction groove.

Detailed Implementation

[0052] To further understand the content of this invention, a detailed description of the invention will be provided in conjunction with the accompanying drawings and embodiments.

[0053] The structures, proportions, and sizes illustrated in the accompanying drawings are merely for illustrative purposes and to aid those skilled in the art in understanding and reading the invention. They are not intended to limit the scope of the invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of the invention, should still fall within the scope of the technical content disclosed herein. Furthermore, terms such as "upper," "lower," "left," "right," and "middle" used in this specification are merely for clarity and not intended to limit the scope of implementation. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention's implementation.

[0054] In one embodiment, such as Figure 1-6As shown, this invention proposes a conveyor line with emergency rail breakage capability, including a rack and pinion guide rail, a rack and pinion connecting guide rail 6, a connector 7, a carrier guide rail, a carrier connecting guide rail 3, a rack 8, and a cutting mechanism. The rack and pinion guide rail is fixedly installed on the conveyor line frame. This rack and pinion guide rail has a gap corresponding to the position of the fire door. In this embodiment, the rack and pinion guide rail can be divided into a first rack and pinion guide rail 4 and a second rack and pinion guide rail 5, with a gap between them to allow the fire door to fall.

[0055] The rack and pinion connecting rail 6 is a separate component from the rack and pinion guide rail. This separation means that the rack and pinion connecting rail 6 and the rack and pinion guide rail are not integral; there is a gap between them. This rack and pinion connecting rail 6 is installed in the gap. When the rack and pinion connecting rail 6 is disconnected from the rack and pinion guide rail, the fire door will not be obstructed and can fall through the gap.

[0056] Specifically, the two ends of the rack connecting guide rail 6 are connected to the rack guide rail via connectors 7 to form a rack running guide rail. In this embodiment, the first rack guide rail 4, the rack connecting guide rail 6, and the second rack guide rail 5 are arranged sequentially. The rack connecting guide rail 6 is separately arranged from the first rack guide rail 4 and the second rack guide rail 5, and the two ends of the rack connecting guide rail 6 are connected to the first rack guide rail 4 and the second rack guide rail 5 via connectors 7 to form a rack running guide rail.

[0057] The vehicle guide rail is connected to the rack and pinion guide rail, and the vehicle guide rail also has a gap corresponding to the fire door. A vehicle connecting guide rail 3 is provided at this gap. This vehicle connecting guide rail 3 is connected to the rack and pinion connecting guide rail 6, and is set separately from the vehicle guide rail to form a vehicle running guide rail. The separate setting here means that there is a gap between the vehicle connecting guide rail 3 and the vehicle guide rail.

[0058] In this embodiment, the vehicle guide rail can be divided into a first vehicle guide rail 1 and a second vehicle guide rail 2. The first rack guide rail 4, the rack connecting guide rail 6, and the second rack guide rail 5 are respectively connected to the first vehicle guide rail 1, the vehicle connecting guide rail 3, and the second vehicle guide rail 2. The vehicle connecting guide rail 3 is separately configured from the first vehicle guide rail 1 and the second vehicle guide rail 2 to form the vehicle running guide rail.

[0059] The rack 8 is a single unit, mounted on the rack running guide rail. This single-unit configuration means the rack can be assembled from segmented sub-components. Once mounted on the rack running guide rail, the sub-components cannot separate on their own, and the entire rack 8 is driven by a rack drive mechanism.

[0060] A drive component 9 is installed on the rack 8. When the rack drive mechanism drives the rack 8 to run, the drive component 9 drives the carrier to move along the carrier running guide rail.

[0061] In this embodiment, the driving component 9 can be a driving rod, which pushes the vehicle to move along the vehicle running guide rail. It should be noted that the driving component 9 is not limited to a driving rod; other structures capable of driving the vehicle to move along the vehicle running guide rail are also acceptable.

[0062] Before the connector 7 is cut, the rack and pinion connecting rail 6 is attached to the rack and pinion guide rail via the connector 7. When a fire occurs, the cutting mechanism can cut the connector 7 and the rack 8. At this time, the rack and pinion connecting rail 6 is no longer attached and falls down, and the carrier connecting rail 3 also falls down. That is, the rack and pinion connecting rail 6 and the carrier connecting rail 3 are respectively separated from the rack and pinion running rail and the carrier running rail. The fire door is no longer obstructed and can fall from the gap where the rack and pinion connecting rail 6 and the carrier connecting rail 3 are installed.

[0063] It should be noted that in this embodiment, there are gaps between the two ends of the vehicle connecting rail 3 and the ends of the first vehicle rail 1 and the second vehicle rail 2, but these gaps will not prevent the vehicle from passing through. Since the vehicle connecting rail 3 is only connected to the rack connecting rail 6 at this time, when the connector 7 and the rack 8 are cut off, the vehicle connecting rail 3 will fall off together with the rack connecting rail 6.

[0064] In one embodiment, such as Figure 5 As shown, the cutting mechanism includes a first drive mechanism 13, which drives a second drive mechanism 15 to move toward the point to be cut of the connector 7 and the rack 8. The second drive mechanism 15 drives a cutting blade 14 to cut the connector 7 and the rack 8. When it is necessary to cut the connector 7 and the rack 8, the first drive mechanism 13 first drives the second drive mechanism 15 to move toward the point to be cut of the connector 7 and the rack 8. At the same time, the cutting blade 14 also moves toward the point to be cut of the connector 7 and the rack 8. Simultaneously, the second drive mechanism 15 drives the cutting blade 14 to move. When the cutting blade 14 contacts the connector 7 and the rack 8, it begins to cut the connector 7 and the rack 8.

[0065] Specifically, the cutting mechanism includes two slide rails 11 mounted on the conveyor frame. The slide rails 11 are located above the rack and pinion connecting guide rail 6 and are horizontally positioned, perpendicular to the rack and pinion connecting guide rail 6. Slider blocks 12 are mounted on the two slide rails 11, and a first drive mechanism 13 can drive the sliders 12 to move along the slide rails 11. The first drive mechanism 13 can be a cylinder, an electric push rod, a linear module, etc. The specific first drive mechanism 13 is not limited here, as it is relatively mature in the prior art and will not be elaborated further.

[0066] The second drive mechanism 15 is mounted on the slider 12. The second drive mechanism 15 can drive the cutting blade 14 to perform up-and-down reciprocating motion, such as a cylinder, electric push rod, linear module, etc. The second drive mechanism 15 can also be a motor that drives the cutting blade to rotate. The second drive mechanism 15 is not limited here, as it is relatively mature in the prior art and will not be described in detail here.

[0067] In one embodiment, the connector 7 includes a side connector and a top connector. Both the side connector and the top connector are simultaneously fixedly connected to the rack guide rail and the rack connecting guide rail 6, that is, simultaneously fixedly connected to the first rack guide rail 4, the rack connecting guide rail 6, and the second rack guide rail 5. For example, they can be connected by screws, which is a mature technology in the prior art and will not be described in detail here. This fixed connection method is not limited here.

[0068] In this embodiment, the side connector is provided with a slot 7.1, which is adapted to the side mounting plate 6.1 of the rack guide rail and the rack connecting guide rail 6, that is, it is adapted to the side mounting plate 6.1 of the first rack guide rail 4, the rack connecting guide rail 6, and the second rack guide rail 5. The side connector is also provided with a connecting part 7.2, which is adapted to the guide cavity 6.2 of the rack guide rail and the rack connecting guide rail 6, that is, it is adapted to the guide cavity 6.2 of the first rack guide rail 4, the rack connecting guide rail 6, and the second rack guide rail 5.

[0069] The top connector is provided with a limiting groove 7.3 for accommodating the cutting blade 14. In this embodiment, the side connector and the top connector connect the two ends of the rack connecting guide 6 to the first rack guide 4 and the second rack guide 5 respectively, thereby connecting the rack connecting guide 6 to the rack guide.

[0070] In one embodiment, such as Figure 7-10 As shown, the connector 7 has a centrally located partition 7.4 that matches the end faces of the rack guide rail and the rack connecting guide rail 6. Both ends of the partition 7.4 have insertion posts 7.5 that match the insertion holes on the end faces of the rack guide rail and the rack connecting guide rail 6. In this embodiment, the partition 7.4 matches the end faces of the first rack guide rail 4, the rack connecting guide rail 6, and the second rack guide rail 5, and both ends of the partition 7.4 have insertion posts 7.5 that match the insertion holes on the end faces of the first rack guide rail 4, the rack connecting guide rail 6, and the second rack guide rail 5. The two ends of the rack connecting guide rail 6 are connected to the first rack guide rail 4 and the second rack guide rail 5 respectively, thereby connecting the rack connecting guide rail 6 to the rack guide rail.

[0071] In one embodiment, the invention further includes a controller electrically connected to the rack drive mechanism, the first drive mechanism 13, and the second drive mechanism 15, the controller being used to control the start and stop of the rack drive mechanism, the first drive mechanism 13, and the second drive mechanism 15.

[0072] The controller is also electrically connected to a first detection mechanism 16 and a second detection mechanism 17. The first detection mechanism 16 is located at the end of the slider 12 in the running direction and is used to detect whether the connector 7 and the rack 8 are cut off. The second detection mechanism 17 is located above the rack connecting guide rail 6 and is used to detect whether the fire door has fallen.

[0073] Specifically, when the second detection mechanism 17 detects the fire door falling, the controller stops the rack and pinion drive mechanism from driving the rack 8 and opens the first drive mechanism 13 and the second drive mechanism 15, allowing the cutting blade 14 to cut the connector 7 and the rack 8. When the first detection mechanism 16 detects the cutting blade 14, it means that the cutting blade 14 has cut the connector 7 and the rack 8, at which point the controller closes the first drive mechanism 13 and the second drive mechanism 15.

[0074] In one embodiment, the first detection mechanism 16 and the second detection mechanism 17 can be selected from proximity sensors, which are relatively mature in the prior art and will not be described in detail here. No limitation is made here.

[0075] In one embodiment, a gap exists between the two ends of the vehicle connecting rail 3 and the vehicle guide rail, and a transition mechanism is provided at this gap. It should be noted that even without the transition mechanism, the gap between the two ends of the vehicle connecting rail 3 and the vehicle guide rail will not impede the vehicle's passage, but the vehicle's passage will not be smooth. The transition mechanism is used to ensure smooth operation of the vehicle between the first vehicle guide rail 1 and the vehicle connecting rail 3, and between the second vehicle guide rail 2 and the vehicle connecting rail 3.

[0076] As an optional implementation, the transition mechanism is a transition overlap 18. The transition overlaps 18 at both ends of the vehicle connecting rail 3 are connected to either the vehicle rail or the vehicle connecting rail 3, respectively. That is, only one end of the transition overlap 18 is connected to the rail, and the other end rests only on the rail on the other side. When the vehicle connecting rail 3 falls, the transition overlap 18 will not obstruct its fall.

[0077] As another optional implementation, both ends of the vehicle connecting guide rail 3 and the end of the vehicle guide rail are provided with constriction grooves 23. The transition mechanism includes a third drive mechanism 22 installed on the vehicle guide rail. This third drive mechanism 22 is used to drive the connecting block 24 to slide along the constriction groove 23.

[0078] The third drive mechanism 22 is also electrically connected to the controller. The third drive mechanism 22 can be a cylinder, an electric actuator, a linear module, etc. There is no limitation on the third drive mechanism 22 here, as this is relatively mature in the existing technology and will not be described in detail here.

[0079] Specifically, both the first vehicle guide rail 1 and the second vehicle guide rail 2 have constriction grooves 23 at their ends. The transition mechanism includes a third drive mechanism 22 mounted on the first vehicle guide rail 1 and the second vehicle guide rail 2. This third drive mechanism 22 drives the connecting block 24 to move to the alignment point between the end of the vehicle connecting guide rail 3 and the end of the vehicle guide rail, thereby providing support and alignment for the vehicle connecting guide rail 3, allowing the vehicle to move smoothly at this point. In the event of a fire, the third drive mechanism 22 drives the connecting block 24 to move away, allowing the vehicle connecting guide rail 3 to fall down along with the rack connecting guide rail 6.

[0080] In one embodiment, one end of the rack and pinion connecting rail 6 is connected to the rack and pinion guide rail or the conveyor frame via a connecting rope 21. When the rack and pinion connecting rail 6 detaches from the rack and pinion running guide rail, it hangs below the rack and pinion guide rail, avoiding the installation location of the rack and pinion connecting rail 6. Because the rack and pinion connecting rail 6 hangs below the rack and pinion guide rail after falling, it can prevent falling objects from obstructing the closing of the fire door.

[0081] In one embodiment, the vehicle guide rail and the vehicle connecting guide rail 3 are both connected to the rack guide rail and the rack connecting guide rail 6 respectively via brackets 10. Specifically, the brackets 10 are C-shaped, and the first vehicle guide rail 1, the vehicle connecting guide rail 3, and the second vehicle guide rail 2 are respectively connected to the first rack guide rail 4, the rack connecting guide rail 6, and the second rack guide rail 5 via at least two C-shaped brackets 10.

[0082] In one embodiment, the rack 8 is a flexible rack, and the connector 7 and the rack 8 can be made of easily cut plastic. However, it should be noted that the material of the connector 7 and the rack 8 is sufficient to allow them to be cut, and they are not limited to being made of plastic.

[0083] In one embodiment, the conveyor line is a loop conveyor line, thus having two paths, one in each direction.

[0084] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the present invention, such designs should fall within the protection scope of the present invention.
