Description

Technical Field

[0001] The present invention relates to the technical field of logistics conveying equipment, and particularly relates to a large-capacity buffer conveying device and a conveying method. Background Art

[0002] The on-line buffer conveying device is one of the very important devices in the logistics conveying process. Especially in the production process of cigarette rods or filter rods, the buffering and conveying of materials are indispensable devices for connecting the upstream and downstream continuous production. In the production and conveying process of some materials, not only a storage device is needed to adjust the speed difference between the upstream and downstream machines, but also a long conveying time is required to enable some characteristics of the materials themselves to be fully integrated and stabilized.

[0003] For materials such as filter rods, a certain curing time is required to form, and then they can enter the transmitter. And this time also varies depending on the different curing agents of the filter rods. In order to maximize the production capacity, a large-capacity buffer conveying device is needed to complete the conveying.

[0004] However, the existing large-capacity conveying and buffering are all composed of a hoist, a conveying channel, a cabinet-type buffer device and a cabinet-type conveying device. The length and number of layers of the cabinet determine the curing time. Such devices have the following technical problems when in use: (1) The device is designed with an integrated structure, resulting in too large an overall floor area; (2) There are too few layout methods for the devices with an integrated structure design, which is not flexible; (3) The traditional cabinet-type storage method requires turning on each layer, and the number of turns is too many, causing serious rubbing and squeezing of the filter rods; (4) For filter rods with a long curing time, devices with a larger conveying capacity are required, resulting in low versatility of the traditional cabinet-type conveying device. Summary of the Invention

[0005] The purpose of the present invention is to propose a large-capacity buffer conveying device and a conveying method to solve the problems that the traditional cabinet-type conveying device has a large floor area, is not flexible to adjust, and cannot adapt to filter rods with different curing times.

[0006] To achieve the above purpose, the present invention adopts the following technical solution: A large-capacity buffer conveying device includes a spiral first-in-first-out storage device with an upper inlet and a lower outlet. Both the inlet and the outlet of the storage device are connected to at least one conveying device through a conveying channel, and the conveying devices located on both sides of the storage device are respectively connected to an upstream machine and a downstream machine installed outside through a conveying channel.

[0007] The spiral conveyor mechanism disposed inside the conveying device includes a cylinder body, and a cantilever conveyor chain plate spirally arranged around the cylinder body and forming a closed loop. The inner side of the cantilever conveyor chain plate is slidably arranged on the corresponding spiral chute on the outer wall of the cylinder body, and the upper and lower ends respectively pass through the corresponding through holes on the cylinder wall and extend inward and then are slidably connected with the chain plate fixing guide rails inside the cylinder body until they are connected to the first tensioning mechanism at the lower part of the driving mechanism at the inner bottom of the cylinder body and the damping idler mechanism at the bottom;

[0008] The slack of the cantilever conveyor chain plate is adjusted by the first tensioning mechanism and the damping idler mechanism at the bottom, so as to ensure that the conveying device forms a conveying chain for stable conveying of filter rods that can be connected through a single conveying channel while being wound and switched around the storage device.

[0009] Further description by adopting the above scheme:

[0010] The upper and lower ends of the storage device are respectively connected to the conveying device through a conveying channel, forming a vertical path from feeding to storage and then discharging to another conveying;

[0011] The rotation directions of the cantilever conveyor chain plates in adjacent conveying devices are opposite, and the rotation directions of the cantilever conveyor chain plates in the conveying devices on both sides of the storage device are the same.

[0012] Further description by adopting the above scheme:

[0013] The driving mechanism includes a chain plate wheel matched with the cantilever conveyor chain plate. The chain plate wheel is connected to the output shaft of the speed reducer inside the cylinder body, and the input shaft of the speed reducer is connected with a first power machine.

[0014] The first tensioning mechanism includes a fixed support plate installed inside the cylinder body. A group of slide rails and sliders matched with the slide rails are fixed on the fixed support plate. A group of the sliders are fixed with an arc-shaped fixed guide rail through a connected support seat. Fixed columns are installed on both the fixed support plate and the support seat, and a spring is fixed between the two fixed columns.

[0015] Further description by adopting the above scheme:

[0016] The damping idler mechanism includes a bracket and a chain plate idler installed on the bracket through a fixed shaft. A damper is installed inside the chain plate idler.

[0017] Further description by adopting the above scheme:

[0018] A conveying mechanism is installed inside the conveying channel. The conveying mechanism includes a first cross plate and a second cross plate fixedly installed in the channel. A power mechanism, a fixed wheel and a second tensioning mechanism are installed on the cross plates. A conveyor belt is sleeved on the driving wheel of the power mechanism, the fixed wheel and the idler at the output end of the second tensioning mechanism.

[0019] A conveying method for a large-capacity cache conveying device, comprising the following steps:

[0020] S1. Place the conveying device at different positions, transfer the filter rods from the upstream machine through the conveying channel to the conveying device, then transfer them to the storage device through the conveying device, and transfer them to the next conveying device through the storage device to achieve chain-type conveying of the filter rods;

[0021] S2. Utilize the cooperation of the driving mechanism, the first tensioning mechanism, and the damping idler wheel mechanism to enable the cantilever conveying chain plate to slide stably in the corresponding spiral chute to achieve smooth operation of the filter rods.

[0022] In summary, due to the adoption of the above technology, a large-capacity cache conveying device and a conveying method, the beneficial effects of the present invention are:

[0023] Place the conveying device at different positions, transfer the filter rods from the upstream machine through the conveying channel to the conveying device, and then transfer them to the storage device through the conveying device, and transfer them to the next conveying device through the storage device to achieve chain-type conveying of the filter rods. Since the positions of each conveying device can be flexibly arranged to form a chain-shaped conveying path, compared with the overall conveying equipment composed of traditional cabinet-type cache devices and cabinet-type conveying devices, the layout method is more flexible and can be adjusted according to actual needs, so that it does not occupy a large area. For filter rods with a long curing time, there is no need for a device with a large conveying capacity, and only the number of conveying devices needs to be increased or decreased, thereby improving the application range of the conveying device. In addition, by using the cantilever conveying chain plate to slide in the corresponding spiral chute, the entire conveying process of the filter rods will not have too many turning times, reducing the rubbing of the filter rods. At the same time, in cooperation with the first tensioning mechanism and the damping idler wheel mechanism, the chain can be prevented from skipping teeth or derailing, realizing multi-stage stable conveying of the material and improving the conveying efficiency.

[0045] Next, the accompanying drawings in the embodiments of the present invention will be combined to clearly and completely describe the technical solution of a large-capacity buffer conveying device and a conveying method in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

[0046] As Figures 1 - 3 、 Figures 9 - 12 shown, the present invention provides: a large-capacity buffer conveying device, including a spiral first-in-first-out storage device 5 with an upper inlet and a lower outlet. Both the inlet and the outlet of the storage device 5 are connected to at least one conveying device 3 through a conveyor channel 2. The conveying devices 3 located on both sides of the storage device 5 are respectively connected to an upstream machine 1 and a downstream machine 11 installed outside through the conveyor channel 2;

[0047] The spiral conveyor mechanism 32 disposed inside the storage device 5 and the conveying device 3 includes a cylinder body 31 and a cantilever conveyor chain plate 321 spirally arranged around the cylinder body 31 to form a closed loop. The inner side of the cantilever conveyor chain plate 321 is slidably disposed on the corresponding spiral chute 311 on the outer wall of the cylinder body 31, and the upper and lower ends respectively pass through the corresponding through holes on the wall of the cylinder body 31 and extend inward, and then are slidably connected to the chain plate fixing guide 322 inside the cylinder body 31 until they are connected to the first tensioning mechanism 324 at the lower part of the driving mechanism 323 at the inner bottom of the cylinder body 31 and the damping idler mechanism 325 at the bottom; among them, compared with the ordinary conveying device 3, the storage device 5 has two spiral conveyor mechanisms 32 with opposite directions on the cylinder body 31. Specifically, reference can be made to a spiral first-in-first-out storage device with the publication number of CN117326260A in the prior art. As the upper and lower spiral conveyor mechanisms 32 with opposite spiral directions rotate, the materials are continuously stored from bottom to top on the lower and upper spiral conveyor mechanisms 32 until they are full; when discharging materials, by using the lowering of the lifting type feeding transition conveyor mechanism and the rising of the lowering type discharging transition conveyor mechanism inside it, the materials on the upper and lower spiral conveyor mechanisms 32 are gradually emptied from bottom to top, thus completing the first-in-first-out of the materials.

[0048] Further in detail, as Figures 1 - 4 , Figures 12 - 17 shown, the driving mechanism 323 includes a chain plate wheel 3231 that is matched with the cantilever conveyor chain plate 321. The chain plate wheel 3231 is connected to the output shaft of a speed reducer 3232 inside the cylinder body 31, and the input shaft of the speed reducer 3232 is connected to a first power machine 3233; the cooperation between the first power machine 3233 and the speed reducer 3232 can adjust the rotation speed of the chain plate wheel 3231, thereby realizing the speed adjustment of the cantilever conveyor chain plate 321, enabling the cantilever conveyor chain plate 321 to convey the materials smoothly and achieving a primary buffering effect on the material conveyance.

[0049] Further in detail, as Figures 1 - 4 and Figure 17As shown, the first tensioning mechanism 324 includes a fixed support plate 3246 installed inside the cylinder body 31. A set of slide rails 3243 and sliders 3242 matching the slide rails 3243 are fixed on the fixed support plate 3246. A set of the sliders 3242 are fixed with an arc-shaped fixed guide rail 3245 through a connected support seat. Fixed columns 3244 are installed on both the fixed support plate 3246 and the support seat, and a spring 3241 is fixed between the two fixed columns 3244. The slider 3242 slides on the slide rail 3243, enabling the fixed column 3244 to stretch or compress the spring 3241. When the spring 3241 is stretched or compressed, the arc-shaped fixed guide rail 3245 can adapt to different relaxation degrees of the cantilever conveyor chain plate 321. The spring 3241 connects the moving seat and the fixed column 3244, automatically adjusting the chain plate tightness through elastic deformation, compensating for the length change caused by wear or thermal expansion and contraction, preventing slipping or jamming. At the same time, it buffers the impact load during operation, reduces component wear, and extends the service life. It plays a secondary buffering effect on material transportation.

[0050] Among them, by using the cantilever conveyor chain plate 321 to slide in the corresponding spiral chute 311, the entire transportation process of the filter rod will not have too many turning times, reducing the squeezing of the filter rod and improving the transportation efficiency.

[0051] Further in detail, as Figures 1 - 4 and Figure 19 shown, the damping idler mechanism 325 includes a bracket 3251 and a chain plate idler 3252 installed on the bracket 3251 through a fixed shaft. A damper 3253 is installed inside the chain plate idler 3252.

[0052] The chain plate idler 3252, as a guiding component of the chain drive system, is prone to violent vibration due to the instantaneous impact force of the chain during high-speed or heavy-load operation. The damper 3253 absorbs the kinetic energy transmitted by the chain through internal friction or viscous resistance and dissipates it as heat energy, thereby reducing the impact noise and mechanical wear between the chain and the idler. When the chain generates an inertial impact due to a sudden change in load or start-stop action, the damper 3253 can suppress the instantaneous acceleration of the chain plate idler 3252 and prevent the chain from skipping teeth or derailing. The damping idler mechanism 325 plays a tertiary buffering effect on material transportation.

[0053] By adjusting the relaxation degree of the cantilever conveyor chain plate 321 through the first tensioning mechanism 324 and the damping idler mechanism 325 at the bottom, it is ensured that the conveying device 3 is switched and placed around the storage device 5 while forming a conveyor chain that can stably convey the filter rod through a single conveying channel 2.

[0054] As Figures 1 - 2 、 Figures 8 - 11As shown, the upper and lower ends of the storage device 5 are respectively connected to the conveying device 3 through the conveying channels 2, forming a vertical path for feeding into storage and then discharging to another conveying.

[0055] Among them, the rotating directions of the cantilever conveying chain plates 321 in adjacent conveying devices 3 are opposite, and the rotating directions of the cantilever conveying chain plates 321 in the conveying devices 3 on both sides of the storage device 5 are the same; the conveying device 3 connected to the inlet of the storage device 5 is a left helix, its inlet height is the same as the outlet height of the upstream machine 1, and its outlet height is the same as the inlet height of the spiral first-in-first-out storage device 5; the conveying device 3 connected to the outlet of the storage device 5 is also a left helix, its inlet height is the same as the outlet height of the spiral first-in-first-out storage device 5, and its outlet height is the same as the inlet height of the third conveying device 3. If there is no third conveying device 3, it is the same as the inlet height of the downstream machine 11; the third conveying device 3 is a right helix, its inlet height is the same as the outlet height of the previous conveying device 3, and its outlet height is the same as the inlet height of the downstream machine 11, forming a vertical path for feeding into storage and then discharging to another conveying.

[0056] Place the conveying device 3 at different positions, transfer the filter rods coming out of the upstream machine 1 to the conveying device 3 through the conveying channel 2, then transfer them to the storage device 5 through the conveying device 3, and transfer them to the next conveying device 3 through the storage device 5, realizing the chain-type conveying of the filter rods. Since the position of each conveying device 3 can be flexibly placed, forming a chain-shaped conveying path, compared with the overall conveying equipment composed of traditional cabinet-type buffer devices and cabinet-type conveying devices, the layout method is more flexible and can be adjusted according to actual needs, so that it does not occupy a large area. For filter rods with a long curing time, there is no need for a device with a large conveying capacity, and only the number of conveying devices 3 needs to be increased or decreased, improving the application range of the conveying device 3.

[0057] As Figures 1 - 2 , Figures 5 - 7 and Figure 16 , a conveying mechanism is installed inside the conveying channel 2. The conveying mechanism includes a first cross plate 27 and a second cross plate 28 fixedly installed in the channel. A power mechanism 22, a fixed wheel 24, and a second tensioning mechanism 26 are installed on the cross plates. A conveyor belt 21 is sleeved on the driving wheel 221 of the power mechanism 22, the fixed wheel 24, and the idler wheel 25 of the second tensioning mechanism 26.

[0058] More specifically, the inside of the conveying channel 2 further includes a transition plate installed on the first cross plate 27 and the second cross plate 28. The transition plate plays a role in propping up and transitioning the material. The transition plate is connected to the cantilever conveying chain plate 321 of the conveying device 3. One end of the conveying channel 2 without a transition plate is connected to the outlet or inlet of the spiral first-in-first-out storage device 5, the upstream machine 1, and the downstream machine 11.

[0059] As Figures 1 - 8 shown, in further detail, the power mechanism 22 includes a drive group, a power group, a support plate, and a transmission belt. The drive group includes a transmission belt pulley, a rotating shaft, a bearing seat, a drive wheel 221, and a support block. The transmission belt pulley, the bearing seat, and the drive wheel 221 are disposed on the rotating shaft and are fixed on the first horizontal plate 27 of the channel through the support plate and the support block. The power group includes a third power machine, a speed reducer, and a transmission belt pulley. The third power machine and the transmission belt pulley are respectively disposed on the input shaft and the output shaft of the speed reducer. The speed reducer is fixed on the first horizontal plate 27 of the channel through the support plate. The third power machine acts on the drive wheel 221 through the speed reducer and via the transmission belt to drive the conveyor belt 21 to move.

[0060] A conveying method for a large-capacity buffer conveying device includes the following steps:

[0061] S1. Place the conveying device 3 at different positions, transfer the filter rods coming out of the upstream machine 1 through the conveying channel 2 to the conveying device 3, then transfer them to the storage device 5 through the conveying device 3, and transfer them to the next conveying device 3 through the storage device 5 to achieve the chain-type conveying of the filter rods;

[0062] S2. Utilize the cooperation of the drive mechanism 323, the first tensioning mechanism 324, and the damping idler mechanism 325 to enable the cantilever conveying chain plate 321 to stably slide in the corresponding spiral chute 311 to achieve the smooth operation of the filter rods.

[0063] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
