Description

Technical Field

[0001] The invention relates to the technical field of fiber felt production equipment, and in particular to an efficient fiber felt stacking system and stacking method. Background Art

[0002] Metal fiber felt is a porous material interwoven with fine metal fibers. It has unique physical and chemical properties, such as high porosity, high temperature resistance, corrosion resistance, etc. It is suitable for a variety of industrial applications, such as filter media, catalyst carriers, heat exchangers, electromagnetic shielding, etc.

[0003] There are two forms of metal fiber felt production. One is that the fiber filaments are suspended in a liquid environment and then naturally settle. The other is that the fiber filaments float in the atmospheric environment and then settle to form a felt-like structure. The strip-shaped single-layer metal fiber felt needs to be cut into sheets first, then stacked layer by layer, and then sintered to form a semi-finished product. As we all know, before sintering, the single-layer metal fiber felt is soft and has no self-support. If it is subjected to external force during transportation or stacking, it is very easy to cause the evenly distributed fiber filaments to be stretched or stacked, resulting in uneven pore size distribution and uneven quality of the final product.

[0004] In existing production practices, single-layer metal fiber felt is often manually stacked. During the transportation and stacking process, the fiber felt is subjected to external forces, which may cause the fiber filaments to be stretched or stacked, which is not conducive to improving the quality of the finished product.

[0005] In the prior art, there is also a mechanical stacking method, such as Figure 1 As shown, in order to adapt to the existing fiber felt production line, the cutting knife cuts the strip fiber felt output by the production line, and the cut fiber felt is dropped to the receiving table through the loading unit, and the receiving table moves left and right to complete the stacking of the fiber felt. When an odd number of fiber felt layers need to be stacked, the receiving table moves right to complete the stacking, and when an even number of fiber felt layers need to be stacked, the receiving table moves left to complete the stacking. This is suitable for continuous production, but is not conducive to improving production efficiency.

[0006] In addition, if Figure 1 As shown, an arc-shaped connecting area is formed between adjacent layers of fiber felts. The arc-shaped connecting area needs to be cut and removed before entering the next process, or cut and removed after the subsequent process. This not only causes waste of fiber felts, but also the arc-shaped connecting area is easy to squeeze adjacent fiber felts when stacked, which is not conducive to improving the uniformity of the pore size distribution of the fiber felts and the quality of the finished product. Summary of the invention

[0007] The present invention discloses an efficient fiber mat stacking system and stacking method, which solves the technical problems in the prior art that fiber mat stacking cannot adapt to continuous production and is not conducive to improving the uniformity of the pore size distribution of the finished product after stacking. It has a reasonable structure, convenient operation, and is conducive to improving the uniformity of the pore size distribution of the finished product after stacking. The technical solution adopted is as follows: An efficient fiber felt stacking system, comprising: A support plate, which is arranged below the feeding unit and is used to receive the fiber mat; the feeding unit comprises a first conveyor belt, which conveys the cut sheet-like fiber mat to the support plate; A circulation unit, wherein the circulation unit includes a track assembly and a driving unit, wherein the track assembly supports the pallet upwards, and the driving unit can drive the pallet to move along the loop of the track assembly so that the pallet receives the fiber mat from the loading unit multiple times to complete the stacking of the fiber mat; or the driving unit can drive the pallet out of the track assembly to transfer the pallet and the fiber mat to the next workstation.

[0008] On the basis of the above technical solution, the driving unit is designed so that when the pallet receives the fiber mat, the driving unit drives the pallet and the first conveyor belt to move at the same linear speed.

[0009] On the basis of the above technical solution, it also includes a flipping drive, which can drive the end of the first conveyor belt to pitch and adjust to get closer to or away from the pallet.

[0010] On the basis of the above technical solution, the track assembly includes a bracket and a plurality of transmission rollers arranged on the bracket, and the transmission rollers support the pallet upward and drive the pallet to move.

[0011] On the basis of the above technical solution, the bracket includes a first length segment, a second length segment, a third length segment and a fourth length segment arranged in a closed loop in the same plane, the head end of the first length segment is arranged close to the first conveyor belt, the first length segment is coaxial with the first conveyor belt and is arranged parallel to the third length segment, the two ends of the second length segment are respectively connected to the head ends of the first length segment and the third length segment, and the two ends of the second length segment form a first transition segment at the connection between the first length segment and the third length segment; the two ends of the fourth length segment are respectively connected to the tail ends of the first length segment and the third length segment, and the two ends of the fourth length segment form a second transition segment at the connection between the first length segment and the third length segment, the second transition segment connecting the first length segment and the fourth length segment includes a first drive roller group and a second drive roller group, the first drive roller group includes a plurality of first drive rollers for transferring the pallet to the next workstation along the axis of the first length segment, the second drive roller group includes a plurality of second drive rollers for transferring the pallet to the fourth length segment, and the plurality of first drive rollers are evenly spaced, and the plurality of second drive rollers are evenly spaced.

[0012] On the basis of the above technical solution, it also includes a first lifting drive and a second lifting drive, the bracket includes a fifth length segment, a sixth length segment, a seventh length segment and an eighth length segment arranged in a closed loop, the head end of the fifth length segment is arranged close to the first conveyor belt, the fifth length segment is coaxial with the first conveyor belt and is arranged parallel to the seventh length segment up and down, the first lifting drive is arranged close to the head ends of the fifth length segment and the seventh length segment, the first lifting drive supports the eighth length segment upward, the second lifting drive is arranged close to the ends of the fifth length segment and the seventh length segment, and the second lifting drive supports the sixth length segment upward.

[0013] On the basis of the above technical solution, the plurality of drive rollers include a plurality of relatively independent drive roller groups, and the driving unit is designed such that, after the pallet receives the fiber felt from the first conveyor belt, the driving unit drives the pallet to accelerate its displacement through the drive roller groups at corresponding positions; when the pallet approaches the first conveyor belt and before receiving the fiber felt, the driving unit drives the pallet to decelerate its displacement through the drive roller groups at corresponding positions, so that the pallet and the first conveyor belt move at the same linear speed.

[0014] Based on the above technical solution, a first sensor group and a second sensor group are further provided on the bracket. When the pallet receives the fiber felt from the first conveyor belt, the first sensor group identifies the pallet and sends a signal to the external controller; when the pallet approaches the first conveyor belt and before receiving the fiber felt, the second sensor group identifies the pallet and sends a signal to the external controller.

[0015] On the basis of the above technical solution, it also includes a third sensor group, which is used to identify the stacking height of the fiber felt on the pallet on the first length segment or the fifth length segment. When the stacking height of the fiber felt exceeds the set range value, the third sensor sends a signal to the external controller to make the pallet escape from the track assembly and be transported to the next workstation.

[0016] A fiber mat stacking method, using the efficient fiber mat stacking system as described above, comprises the following steps: A The cut fiber felt sheets are transported forward by the loading unit; B. The driving unit drives the support plate to move along the loop on the track assembly to receive the fiber mat multiple times to complete the fiber mat stacking; C. After the fiber mat is stacked, the driving unit drives the pallet out of the track assembly and transports it to the next station.

[0017] Beneficial Effects The present invention has a reasonable structure. The support plate is arranged below the loading unit to receive the fiber mat. The support plate is arranged above the track assembly. Under the action of the driving unit, the support plate moves along the track assembly. When the support plate moves along the track assembly loop, the support plate can receive the fiber mat in multiple layers to complete the fiber mat stacking. In this way, it can be adapted to the existing fiber mat production line. When multiple support plates are arranged, continuous production can be achieved, greatly improving production efficiency. In addition, under the action of the driving unit, the support plate can be separated from the track assembly and continue to be transported to the next station. It has good adaptability and can be well connected with the existing fiber mat production line.

[0018] The present invention also includes driving the loading unit to adjust the pitch, which has good flexibility and can be applied to the production of multiple layers of fiber mats. On the other hand, the top surface of the pallet or the stacked fiber mat always maintains a stable drop height with the loading unit to ensure a good drop state of the fiber mat, which is beneficial to improving the quality of the stacking. In addition, the driving unit is also designed so that when the pallet receives the fiber mat, it moves at the same linear speed as the first conveyor belt, which can reduce the pulling or squeezing effect on the fiber mat during the drop process, which is beneficial to improving the drop accuracy.

[0019] The track assembly in the present invention includes the first to fourth length segments arranged in a plane and extending in a closed loop, which occupies a small longitudinal space. When the pallet is repeatedly circulated along the first to fourth length segments, multiple fiber felts can be stacked, which has a high degree of automation and is conducive to reducing labor costs. There are multiple pallets, which is convenient for continuous production. The second transition segment connecting the first length segment and the fourth length segment includes a first transmission roller group and a second transmission roller group. Under the action of the drive unit, the pallet can be switched to continue to be transported in a loop or to be detached from the track assembly, which can further improve the degree of automation and facilitate continuous production. Or the track assembly includes the fifth to eighth length segments arranged in a longitudinal direction and extending in a closed loop, which occupies a small plane space and is convenient for arrangement. When the pallet is repeatedly circulated in the fifth to eighth length segments, a multi-layer fiber felt stacking operation is realized, which has a high degree of automation and is conducive to reducing labor costs. There are multiple pallets, which is convenient for continuous production.

[0020] Among them, the track assembly includes a bracket, on which are provided a number of transmission rollers, which are further divided into a number of transmission roller groups. In this way, the transport speed of the pallet on the track assembly can be flexibly adjusted, so that the pallet can be quickly displaced during the transport process, thereby improving production efficiency. At the same time, it is ensured that the pallet maintains the same linear speed as the first conveyor belt when receiving the fiber felt, and the design is reasonable.

[0021] The present invention also includes multiple groups of sensors, among which the first sensor group is used to identify whether the pallet has received all the fiber felt, the second sensor group is used to identify the distance between the fiber felt to be received and the first conveyor belt, so as to facilitate the control of the pallet to slow down and approach the first conveyor belt, and the third sensor group is used to identify whether the fiber felt on the pallet has reached the set number of stacking layers, so as to facilitate the transfer of the fiber felt to the next process. It has a high degree of automation and greatly improves production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Example 1 like Figure 2 An efficient fiber felt stacking system is shown, comprising: The support plate 1 is arranged below the feeding unit 2 for receiving the fiber felt; in this embodiment, the top and bottom surfaces of the support plate 1 are provided with an anti-skid layer, such as a rubber pad layer, and the anti-skid layer is provided with anti-skid grooves.

[0029] like Figure 2 As shown, the feeding unit 2 includes a first conveyor belt 21, a feeding active roller, a feeding driven roller and a feeding drive. The first conveyor belt 21 is sleeved outside the feeding active roller and the feeding driven roller. The roller shafts of the feeding active roller and the feeding driven roller pass through the side plates 23 on both sides and are rotatably connected to the side plates 23. The feeding drive is fixed on the side plates 23 and transmits the rotational motion to the feeding active roller. Among them, the first conveyor belt 21 is adapted to the existing metal fiber felt production line. The single-layer fiber felt is transported from the production line to the first conveyor belt 21. The fiber felt transported from the fiber felt production line to the first conveyor belt 21 has good left-right position accuracy. The first conveyor belt 21 transports the cut sheet fiber felt to the pallet 1; It also includes a flip drive, and the outer sides of the two side plates 23 are also provided with vertical plates, a pin shaft 22 passes through the two side plates 23 and is fixedly connected to the two side plates 23, and the two ends of the pin shaft 22 are respectively rotatably connected to the vertical plates, and the rotation connection is sleeved with bearings. The flip drive can drive the pin shaft 22 to rotate, and then drive the end of the first conveyor belt 21 to pitch and adjust to get closer to or away from the support plate 1. In this way, on the one hand, it has good flexibility in use and can be adapted to be used in the production of fiber mat stacking with multiple layers. On the other hand, the support plate 1 or the top surface of the stacked fiber mat always maintains a stable drop height with the loading unit 2 to ensure a good drop state of the fiber mat, which is conducive to improving the stacking quality.

[0030] The circulation unit includes a track assembly 3 and a driving unit. The track assembly 3 supports the pallet 1 upward. The driving unit can drive the pallet 1 to move along the loop of the track assembly 3 so that the pallet 1 receives the fiber felt from the loading unit 3 multiple times to complete the stacking of the fiber felt; or the driving unit can drive the pallet 1 out of the track assembly 3 to transfer the pallet 1 and the fiber felt to the next workstation.

[0031] Specifically, the track assembly 3 includes a bracket 31 and a plurality of transmission rollers 32 arranged on the bracket 31. The bracket 31 is fixedly arranged. The transmission rollers 32 support the support plate 1 upward and drive the support plate 1 to move. The plurality of transmission rollers 32 include a plurality of relatively independent transmission roller groups. The plurality of transmission rollers in one transmission roller group are driven by a chain, such as Figure 2 As shown; in this embodiment, the driving unit includes a plurality of independent sub-driving components, and each transmission roller group is powered by a sub-driving component.

[0032] In this embodiment, the bracket 31 includes a fifth length segment 315, a sixth length segment 316, a seventh length segment 317 and an eighth length segment 318 arranged in a closed loop, the head end of the fifth length segment 315 is arranged close to the first conveyor belt 21, the fifth length segment 315 is coaxial with the first conveyor belt 21 and is arranged vertically parallel to the seventh length segment 317; The first lifting drive 300 and the second lifting drive 400 are also included. The first lifting drive 300 is arranged near the beginning of the fifth length segment 315 and the seventh length segment 317. The first lifting drive 300 supports the eighth length segment 400 upwards, as shown in FIG. 2. The first lifting drive 300 includes two first lifting cylinders. The two first lifting cylinders lift the two ends of the eighth length segment 318 and act synchronously. When the eighth length segment 318 rises to the upper limit, the eighth length segment 318 is flush with the fifth length segment 315. When the eighth length segment 318 falls to the lower limit, the eighth length segment 318 is flush with the seventh length segment 317. The second lifting drive 400 is arranged near the ends of the fifth length segment 315 and the seventh length segment 317, and the second lifting drive 400 supports the sixth length segment 316 upwards, as shown in FIG. Figure 2As shown, the second lifting drive 400 includes two second lifting cylinders, which lift the two ends of the sixth length segment 316 and act synchronously. When the sixth length segment 316 rises to the upper limit, the sixth length segment 316 is flush with the fifth length segment 315. When the sixth length segment 316 falls to the lower limit, the sixth length segment 316 is flush with the seventh length segment 317. In this embodiment, the lifting and lowering of the eighth length segment 318 and the sixth length segment 316 are controlled by a set of travel switches, which are electrically connected to the external controller. The travel switches are prior art and will not be described in detail here.

[0033] Among them, when the first lifting drive 300 lifts the eighth length segment 318 to the upper limit and is flush with the fifth length segment 315, the sub-drive component at the corresponding position is actuated to transport the pallet 1 from the eighth length segment 318 to the fifth length segment 315, and then the first lifting drive 300 is reset; in addition, the sub-drive component is also designed that when the pallet passes under the first conveyor belt 21 and receives the fiber felt, the self-drive component drives the pallet 1 and the first conveyor belt 21 to move at the same linear speed, which can reduce the pulling or squeezing effect on the fiber felt during the blanking process, which is beneficial to improving the blanking accuracy.

[0034] In this embodiment, the plurality of drive rollers 32 include a plurality of drive roller groups, and the plurality of drive rollers 32 in one drive roller group are driven by a chain. In addition, the drive unit includes a plurality of independent sub-drive components, and each drive roller group is powered by a sub-drive component. This creates conditions for the pallet 1 to speed up or slow down along the track component 3. Specifically, the drive unit is designed such that after the pallet 1 receives the fiber felt from the first conveyor belt 21, the drive unit drives the pallet 1 to accelerate its displacement through the drive roller groups at the corresponding positions; when the pallet 1 moves from the eighth length segment 318 to the fifth length segment 315, approaches the first conveyor belt 21, and before receiving the fiber felt, the drive unit drives the pallet 1 to slow down its displacement through the drive roller groups at the corresponding positions, so that the pallet 1 and the first conveyor belt 21 move at the same linear speed.

[0035] In this way, the driving unit can drive the pallet 1 to move along the circular line of the track assembly 3, so that the pallet 1 receives the fiber felt from the loading unit 2 multiple times to complete the stacking of the fiber felt; when the stacking of the fiber felt is completed, the second lifting drive 400 drives the sixth length segment 316 to rise to the upper limit, and then the sub-drive assembly at the corresponding position is actuated to transfer the pallet 1 and the fiber felt thereon to the next workstation, and out of the track assembly 3, and then the second lifting drive 400 is reset.

[0036] In the present embodiment, there are multiple pallets 1, and multiple pallets 1 are transported on the track assembly 3 at the same time, which can not only adapt to the existing fiber felt production line, but also realize continuous production, greatly improving production efficiency; in addition, when a pallet 1 escapes from the track assembly 3 and is transported to the next workstation, a new pallet 1 is added to the circulation assembly 3 by the worker or the upper plate unit, ensuring that there are always a fixed number of pallets 1 in operation on the circulation assembly 3 to maintain a stable production rhythm.

[0037] To facilitate automatic control, the bracket 31 is also provided with a first sensor group, a second sensor group and a third sensor group. When the pallet 1 receives the fiber mat from the first conveyor belt 21, the first sensor group identifies the pallet and sends a signal to the external controller. The controller controls the transmission roller 32 in front of the pallet 1 to accelerate the rotation, so that the pallet 1 accelerates forward. When the pallet 1 approaches the first conveyor belt 21 and before receiving the fiber felt, the second sensor group identifies the pallet 1 and sends a signal to the external controller. The controller controls the transmission roller 32 in front of the pallet 1 to slow down its rotation, so that the pallet 1 slows down its forward movement. Then, when the pallet 1 receives the fiber felt from the first conveyor belt 21 again, the first conveyor belt 21 and the pallet 1 have the same linear speed.

[0038] In this embodiment, the third sensor group is used to identify the stacking height of the fiber mat on the upper pallet 1 at the end of the fifth length segment 315. When the stacking height of the fiber mat exceeds the set range value, the third sensor sends a signal to the external controller to make the pallet 1 escape from the track assembly 3 and be transported to the next station. Among them, the first sensor group, the second sensor group and the third sensor group are existing technologies, and those skilled in the art can select them according to their needs, and will not be repeated here.

[0039] like Figure 2 As shown, the conveying device for conveying the pallet 1 to the next workstation is arranged outside the bracket 31, and forms an extension section when the sixth length section 316 is at the highest limit, so that the pallet 1 can be smoothly removed from the track assembly 3 and enter the next process, ensuring smooth production A fiber mat stacking method, using the efficient fiber mat stacking system as described above, comprises the following steps: A The cut sheet fiber mat is transported forward by the feeding unit 2; B The driving unit drives the pallet 1 to move along the loop on the track assembly 3 to receive the fiber mat multiple times and complete the stacking of the fiber mat. Specifically, when the fiber mat falls from the first conveyor belt 21 to the pallet 1, the pallet 1 and the first conveyor belt 21 always have the same linear speed. After the pallet 1 receives the fiber mat, the driving unit accelerates the pallet 1 along the track assembly 3. When the pallet 1 moves from the end of the fifth length segment 315 to the sixth length segment 316, the second lifting drive 400 moves the sixth length segment 316 from the upper limit to the lower limit, so that the sixth length segment 316 is flush with the seventh length segment 317; then, the sixth length segment 316 is moved to the lower limit by the second lifting drive 400. The sub-drive assembly corresponding to the seventh length segment 317 is actuated to move the pallet 1 from the sixth length segment 316 to the seventh length segment 317. Afterwards, the pallet 1 continues to accelerate its displacement along the seventh length segment 317 and moves to the eighth length segment 318. At the same time, the second lifting drive 400 is reset to the upper limit. Afterwards, the first lifting drive 300 moves the eighth length segment 318 from the lower limit to the upper limit, so that the eighth length segment 318 is flush with the fifth length segment 315. Afterwards, the pallet 1 decelerates its displacement and moves at the same linear speed as the first conveyor belt 21. At the same time, the third lifting drive 300 is reset to the lower limit. This cycle is repeated until the fiber felt stacking is completed.

[0040] C After the fiber felt is stacked, the driving unit drives the pallet 1 to escape from the track assembly 3 and be transported to the next station. In this embodiment, after the limited felt is stacked, under the action of multiple sub-driving assemblies, the pallet 1 and the fiber felt thereon are positioned to the end of the fifth length segment 315, and then continue to move forward, so that the pallet 1 escapes from the track assembly 3 and is transported to the next station.

[0041] D After a pallet 1 escapes from the rail assembly 3 , an empty pallet 1 is added to the rail assembly 3 , and the empty pallet 1 is designed to be transported on the rail assembly 3 instead of the pallet 1 that escaped from the rail assembly 3 .

[0042] Example 2 The difference between Example 2 and Example 1 is that Figure 3 and 4As shown, the bracket 31 includes a first length segment 311, a second length segment 312, a third length segment 313 and a fourth length segment 314 which are arranged in a closed loop in the same plane. The head end of the first length segment 311 is arranged close to the first conveyor belt 21, the first length segment 311 is coaxial with the first conveyor belt 21 and is arranged parallel to the third length segment 313, the two ends of the second length segment 312 are respectively connected to the head ends of the first length segment 311 and the third length segment 313, and the two ends of the second length segment 312 are connected to the first length segment 311 and the third length segment 313 to form a first transition segment 100, and the first transition segment 100 extends along an arc or a broken line; the two ends of the fourth length segment 314 are respectively connected to the tail ends of the first length segment 311 and the third length segment 313, and the two ends of the fourth length segment 314 are connected to the first length segment 311 and the third length segment 313 to form a second transition segment 200, and the second transition segment 200 extends along an arc or a broken line.

[0043] Among them, the second transition section 200 connecting the first length section 311 and the fourth length section 314 includes a first transmission roller group and a second transmission roller group. The first transmission roller group includes a plurality of first transmission rollers 201 for transferring the pallet 1 to the next workstation along the axis of the first length section 311, and the second transmission roller group includes a plurality of second transmission rollers 202 for transferring the pallet 1 to the fourth length section 314. The plurality of first transmission rollers 201 are evenly spaced, and the plurality of second transmission rollers 202 are evenly spaced, and the second transmission rollers 202 avoid the first transmission rollers 201. In this embodiment, the first transmission roller 201 extends uninterruptedly along its axis, and the second transmission rollers 202 at the corresponding position include multiple length sections along its axial direction to avoid the first transmission roller 201. In addition, a conveying device for conveying the pallet 1 to the next workstation is arranged outside the bracket 31 and forms an extension section of the first length section 311, so that the pallet 1 can be smoothly removed from the track assembly 3 and enter the next process, thereby ensuring smooth production.
