[0070] The present invention provides a T-beam web rack storage and conveying system, such as Figure 1-Figure 3 As shown, it includes a material receiving mobile mechanism 1, a fixed transfer seat 2, a first switching mechanism 3 and a second switching mechanism 4, wherein a trolley 100 for carrying a single piece of a steel skeleton 200 can move back and forth on the material receiving mobile mechanism 1, and an empty trolley 100 is loaded on the material receiving mobile mechanism 1; the fixed transfer seat 2 is used to store and transfer multiple trolleys 100; the first switching mechanism 3 is arranged between the material receiving mobile mechanism 1 and the fixed transfer seat 2, and the first switching mechanism 3 is used to transfer the empty trolley 100 from the fixed transfer seat 2 to the material receiving mobile mechanism 1, or to transfer the trolley 100 after loading from the material receiving mobile mechanism 1 to the fixed transfer seat 2; the second switching mechanism 4 is arranged at the other end of the fixed transfer seat 2 away from the first switching mechanism 3, and the second switching mechanism 4 is used to move the trolley 100 after loading out of the fixed transfer seat 2, or to move the empty trolley 100 into the fixed transfer seat 2.

[0071] like Figure 2 As shown, the preceding equipment sequentially places a plurality of steel bar skeleton sheets 200 into the card slots of the pallet 100. The T-beam web pallet storage and conveying system provided by the present invention, when in use, is used to sequentially stack and load the steel bar skeleton sheets 200 on the empty pallet 100 and store and convey them to the next workstation for tying of the through-length reinforcement.

[0072] The T-beam web pallet storage and conveying system provided by the present invention provides a material receiving moving mechanism 1, and an unloaded pallet 100 automatically moves and receives a steel bar skeleton single piece 200 on the material receiving moving mechanism 1, thereby reducing the labor intensity of the loading process; by providing a first switching mechanism 3, a second switching mechanism 4 and a fixed transfer seat 2, the first switching mechanism 3 can sequentially move the pallet 100 after loading into the fixed transfer seat 2, and the fixed transfer seat 2 can store and transfer multiple pallet trolleys 100, and the pallet 100 after loading can be moved out of the fixed transfer seat 2 in sequence through the second switching mechanism 4 for binding of the through-length reinforcement, and the unloaded pallet 100 can also be moved into the fixed transfer seat 2 through the second switching mechanism 4, thereby realizing the orderly transfer of multiple pallet trolleys 100 after loading and unloaded, and the loading of the steel bar skeleton single piece 200 and the subsequent binding in series with the through-length reinforcement can be carried out simultaneously, thereby improving the production efficiency of the T-beam web.

[0073] In some embodiments, Figure 1 As shown, the material receiving mobile mechanism 1, the first switching mechanism 3, the fixed transfer seat 2 and the second switching mechanism 4 are arranged in sequence along the first direction (X direction), a plurality of fixed transfer seats 2 are provided, and the plurality of fixed transfer seats 2 are arranged in sequence along the second direction (Y direction), and each fixed transfer seat 2 is provided with a plurality of trolleys 100 that are movable along the first direction, and the second direction is perpendicular to the first direction.

[0074] like Figure 1 In the illustrated embodiment, the pallet 100 is located at the material receiving mobile mechanism 1 and carries a steel bar skeleton single piece 200. When the pallet 100 moves along the first direction on the material receiving mobile mechanism 1, mobile loading can be realized. After loading, the pallet 100 moves toward the direction of the first switching mechanism 3 on the material receiving mobile mechanism 1 until it is completely transferred to the first switching mechanism 3. The first switching mechanism 3 can carry the pallet 100 after loading and move along the second direction and select a fixed transfer seat 2 to transfer the pallet 100 after loading to the fixed transfer seat 2. By setting a plurality of fixed transfer seats 2 along the second direction, the pallet 100 can be arranged in multiple rows and columns in the first direction and the second direction on the fixed transfer seat 2 at the same time. In the embodiment of the present invention, the pallet 100 is provided with at least two groups, and each group of multiple pallet 100 can be divided into multiple sections and stored on multiple fixed transfer seats 2, which is conducive to shortening the length of the production line of the web of the T-beam and saving space.

[0075] In some embodiments, the material receiving and moving mechanism 1 includes a material receiving and moving bottom beam 11, a walking track 12, a first transmission roller 13 and a tractor 14. The material receiving and moving bottom beam 11 is extended along a first direction (X direction); the walking track 12 is arranged on the material receiving and moving bottom beam 11 and is arranged along the first direction; the first transmission rollers 13 are arranged in pairs on the material receiving and moving bottom beam 11, and multiple pairs of first transmission rollers 13 are arranged at intervals along the first direction, and the trolley 100 is rollingly supported on the first transmission rollers 13; the tractor 14 is slidably arranged on the walking track 12, and when the tractor 14 moves on the walking track 12, the tractor 14 can tow the trolley 100 to move on the first transmission rollers 13.

[0076] like Figure 4 As shown, in this embodiment, the two movable bottom beams 11 for receiving materials are parallel to each other and are arranged at intervals and connected by a cross beam. A walking track 12 for moving a tractor 14 is arranged between the two movable bottom beams 11 through the cross beam support. The first transmission rollers 13 are rollingly arranged in pairs on the two movable bottom beams 11 for rolling the supporting trolley 100. Preferably, the walking track 12 is arranged at one end of the movable bottom beams 11 for receiving materials. The tractor 14 tows the trolley 100, so that the intermittent movement and positioning of the trolley 100 can be realized, and then the movement and loading of the trolley 100 can be realized, so that the preceding equipment can sequentially place the steel skeleton single piece 200 in the card slot on the trolley 100.

[0077] In some embodiments, the traction vehicle 14 includes a main body 141, a traction drive 142, a lifting drive 143 and a positioning seat 144. The traction drive 142 is configured to drive the main body 141 to move on the walking track 12; the lifting drive 143 is disposed on the main body 141; the positioning seat 144 is disposed at the output end of the lifting drive 143, and the lifting drive 143 can drive the lifting movement of the positioning seat 144. When the positioning seat 144 rises, it can be connected and fixed with the trolley 100 to tow the trolley 100.

[0078] like Figure 3 and Figure 4 As shown, the bottom surface of the trolley 100 is provided with a guide wheel 101, and the guide wheel 101 is matched with the positioning seat 144. When the positioning seat 144 rises, the positioning seat 144 is connected and fixed with the guide wheel 101, and the tractor 14 can pull the trolley 100 to move. The traction drive member 142 can use a chain transmission method to drive the main body 141 to move on the walking track 12, such as Figure 5 As shown, the bottom surface of the main body 141 is provided with V-shaped wheels which cooperate with the walking track 12 to achieve guided movement.

[0079] like Figure 4The material receiving and moving mechanism 1 further includes a first roller driving member 15 , which is configured to drive the rotation of the plurality of pairs of first transmission rollers 13 and thereby drive the trolley 100 to move on the plurality of pairs of first transmission rollers 13 .

[0080] It should be noted that when the tractor 14 pulls the pallet 100 to intermittently move and load materials, the pallet 100 is always supported on multiple pairs of first transmission rollers 13, which is more conducive to the traction movement of the pallet 100 and reduces the friction resistance during the movement. When the pallet 100 is loaded, the tractor 14 stops traction, the lifting drive 143 drives the positioning seat 144 to descend, the first roller drive 15 is started, and the multiple pairs of first transmission rollers 13 can rotate and drive the pallet 100 to move, and then drive the pallet 100 after loading to the first switching mechanism 3. The first roller drive 15 can drive multiple pairs of first transmission rollers 13 at the same time, or it can drive a group of active transmission wheels in a pair of first transmission rollers 13, and then drive other driven transmission wheels in sequence. The transmission method can be chain transmission or gear transmission, etc., which is not limited in this embodiment. Among them, the first roller drive 15 and the traction drive 142 can use motors, and the lifting drive 143 can use cylinders.

[0081] In some embodiments, in order to save design cost and reduce design difficulty, in the embodiments of the present invention, the first switching mechanism 3 and the second switching mechanism 4 have the same structure, but are arranged in different positions. The first switching mechanism 3 is taken as an example for detailed description.

[0082] like Figure 6 As shown, the first switching mechanism 3 includes a switching bottom beam 31 and a moving frame 32, wherein the switching bottom beam 31 is extended along the second direction; the moving frame 32 is slidably arranged on the switching bottom beam 31, and the sliding direction is along the second direction. When the moving frame 32 slides along the switching bottom beam 31, it can selectively connect between multiple fixed transfer seats 2 to move in or out of the pallet 100. It can be understood that the length of the switching bottom beam 31 along the second direction is not less than the layout width of the multiple fixed transfer seats 2, so that when the moving frame 32 slides on the switching bottom beam 31, it can be aligned and connected with any one of the fixed transfer seats 2 to transfer the pallet 100. At the same time, the moving frame 32 can be aligned and connected with the material receiving mobile mechanism 1 during the movement to transfer the pallet 100.

[0083] In some embodiments, the moving frame 32 includes a base frame 321, a moving driving member 322, a second transmission roller 323, and a second roller driving member 324. The base frame 321 is slidably arranged on the switching bottom beam 31; the moving driving member 322 is configured to drive the base frame 321 to slide on the switching bottom beam 31; the second transmission rollers 323 are arranged in pairs on the base frame 321, and multiple pairs of second transmission rollers 323 are arranged at intervals along the first direction to carry the trolley 100; the second roller driving member 324 is arranged on the base frame 321, and the second roller driving member 324 is configured to drive the rotation of multiple second transmission rollers 323 to move the trolley 100.

[0084] like Figure 6 As shown, in the embodiment of the present invention, the mobile driving member 322 is used to drive the chassis 321 to slide on the switching bottom beam 31, and the driving connection mode includes but is not limited to the screw transmission connection or the gear transmission connection. In some embodiments, the mobile driving member 322 is arranged at the middle position of the chassis 321, and the mobile driving member 322 is a double output end, and the double output ends are respectively connected to the connecting rods, and the ends of the connecting rods are provided with gears. The switching bottom beam 31 is provided with a rack connected to the gear meshing transmission. When the double output ends of the mobile driving member 322 rotate to drive the connecting rods to rotate, the gears rotate on the racks, thereby driving the movement of the chassis 321. When the mobile driving member 322 drives the chassis 321 to align with the material receiving mobile mechanism 1 or with any fixed transfer seat 2, the pallet 100 can be transferred to the chassis 321 and carried on multiple pairs of second transmission rollers 323. The second transmission rollers 323 are driven to rotate by the second roller driving member 324 to realize the mobile drive of the pallet 100.

[0085] In some embodiments, the plurality of fixed transfer seats 2 include a first fixed transfer seat and a second fixed transfer seat. The first fixed transfer seat can be unidirectionally moved into the pallet trolley 100 at one end facing the first switching mechanism 3, and the second fixed transfer seat can be unidirectionally moved out of the pallet trolley 100 at one end facing the first switching mechanism 3.

[0086] like Figure 1As shown, in this embodiment, five fixed transfer seats 2 are provided along the second direction, of which four are first fixed transfer seats and the outermost one is a second fixed transfer seat. Each first fixed transfer seat can carry four pallet trolleys 100 at the same time. The pallet trolley 100 can only move from the first switching mechanism 3 to the first fixed transfer seat in one direction, and the reverse movement is restricted; the pallet trolley 100 on the second fixed transfer seat can realize bidirectional movement in and out. Through the first switching mechanism 3 and the second switching mechanism 4, the empty pallet trolley 100 and the loaded pallet trolley 100 can be orderly arranged and stored on the fixed transfer seat 2, and can be moved out and moved in in sequence. It should be noted that, according to the demand and efficiency of the steel skeleton single piece 200 in the T-beam web production line, the present invention preferably sets two groups of pallet trolleys 100, each group includes eight pallet trolleys 100, and the eight pallet trolleys 100 are stored and arranged through two first fixed transfer seats. When loading is required, the rightmost empty pallet trolley 100 on the first fixed transfer seat is first transferred to the second fixed transfer seat through the second switching mechanism 4, and then the empty pallet trolley 100 is transferred to the material receiving mobile mechanism 1 for loading through the first switching mechanism 3, and accordingly the first fixed transfer seat steps into the storage position of one pallet trolley 100 After loading, the trolley 100 is moved into the leftmost storage position of the first fixed transfer seat through the first switching mechanism 3. After repeating the above process to realize the sequential loading of the trolley 100 on the first fixed transfer seat, the second switching mechanism 4 can transfer the loaded trolley 100 to the full-length reinforcement binding station, and execute the loading cycle process of the next empty trolley 100 on the first fixed transfer seat and the process of sequentially transferring the loaded trolley 100 to the full-length reinforcement binding station again. In this way, the loading of the trolley 100 and the subsequent full-length reinforcement binding can be carried out in series at the same time, which greatly improves the production efficiency.

[0087] In some embodiments, the first fixed transfer seat and the second fixed transfer seat both include a transfer base beam 21, a third transmission roller 22 and a third roller driving member 23, the transfer base beam 21 is extended along the first direction; the third transmission rollers 22 are arranged in pairs on the transfer base beam 21, and multiple pairs of third transmission rollers 22 are arranged at intervals along the first direction; the third roller driving member 23 is configured to drive the rotation of the third transmission roller 22 to drive the movement of the trolley 100.

[0088] like Figure 7 As shown, two transfer bottom beams 21 are parallel to each other and spaced apart, and two third transmission rollers 22 in each pair of third transmission rollers 22 are respectively rotatably connected to the two transfer bottom beams 21, and the pallet 100 can be carried on the third transmission rollers 22 and moved along the first direction for transfer. The third roller driving member 23 can be a chain drive to drive the rotation of multiple third transmission rollers 22, or a gear drive drive mode, which is not limited to the specific one.

[0089] It can be understood that in the present invention, the spacing between the two first transmission rollers 13 in each pair of first transmission rollers 13, the spacing between the two second transmission rollers 323 in each pair of second transmission rollers 323, and the spacing between the two third transmission rollers 22 in each pair of third transmission rollers 22 all need to be adapted to the width of the trolley 100 in order to stably support the trolley 100 and drive the movement of the trolley 100.

[0090] In some embodiments, the multiple pairs of third transmission rollers 22 on the first fixed transfer seat are divided into two groups along the first direction, and two third roller driving components 23 are provided. The two third roller driving components 23 respectively drive and connect the two groups of third transmission rollers 22.

[0091] For example Figure 7 , Figure 7 The two sides of the middle dotted line are the first group of third transmission rollers 22 on the left and the second group of third transmission rollers 22 on the right. The multiple pairs of third transmission rollers 22 on the left can carry three trolleys 100 at the same time, and are driven and moved individually by a third roller driving member 23 to move the trolley 100 from left to right; the multiple pairs on the right are used to carry one trolley 100, and are driven and moved individually by another third roller driving member 23 to move the trolley 100 from left to right to the second switching mechanism 4. By setting two groups of independently driven third transmission rollers 22, the unloaded or loaded trolley 100 on the far right side facing the second switching mechanism 4 can be driven and moved individually and transported first, freeing up the storage position, and sending the unloaded trolley 100 to the second fixed transfer seat in advance, or sending the loaded trolley 100 to the subsequent station. When the first switching mechanism 3 transports the loaded pallet 100 to the first fixed transfer seat, because there is an empty storage position, the moving frame 32 of the second switching mechanism 4 does not need to stop at the corresponding first fixed transfer seat. At this time, the moving frame 32 may be transporting an empty or loaded pallet 100. The first switching mechanism 3 and the second switching mechanism 4 can respectively and synchronously perform the transfer switching of the pallet 100 to improve the storage and transportation efficiency; and can reduce the number of simultaneous transfers of multiple pallet trolleys 100 on the first fixed transfer seat, save power and energy, and can effectively utilize the storage positions on the first fixed transfer seat.

[0092] In some embodiments, the first fixed transfer seat also includes a one-way limit device 24, which is in a normally open state to limit the trolley 100 on the first fixed transfer seat; when the trolley 100 moves from the first switching mechanism 3 into the first fixed transfer seat, the one-way limit device 24 can be closed.

[0093] like Figure 8 FIG. 2 is a schematic diagram showing the structure of the one-way limit device 24 in a normally open state. Fig. 9 and Fig.10The figure shows a schematic diagram of the process of the one-way limit device 24 rotating and closing. When the trolley 100 contacts the one-way limit device 24, the trolley 100 can rotate and close the one-way limit device 24, so that the trolley 100 can be smoothly moved into the first fixed transfer seat. When the trolley 100 is completely moved into the first solid transfer seat and disengaged from the one-way limit device 24, the one-way limit device 24 is reset to the normally open state again, thereby limiting the trolley 100 on the first fixed transfer seat to prevent the trolley 100 on the first fixed transfer seat from moving out in the opposite direction.

[0094] In some embodiments, the one-way limit device 24 includes a limit seat 241, a limit column 242 and a limit plate 244. The limit seat 241 is arranged on one end of the transfer bottom beam 21 facing the first switching mechanism 3; the limit column 242 is rotatably connected to the limit seat 241 through a center axis 243, and the center axis 243 is arranged along the second direction; the bottom end of the limit column 242 is away from the side of the first switching mechanism 3 and can abut against the limit plate 244 for one-way rotation limitation.

[0095] Combination Fig. 9 and Fig.10 As shown, the top end of the limit seat 241 is rotatably connected to the limit column 242 through the center axis 243. The center of gravity of the limit column 242 is biased to one side relative to the center axis 243. When the limit column 242 rotates under the action of the eccentric force, it can abut against the limit plate 244 to be in a vertical state. At this time, the top end of the limit column 242 can limit the trolley 100. After the trolley 100 contacts the limit column 242 during the movement process and overcomes the eccentric force, the limit column 242 rotates in the opposite direction and closes the limit, so that the trolley 100 can smoothly move into the first fixed transfer seat.

[0096] In other embodiments, the structure in which the limit column 242 abuts against the limit plate 244 through eccentric force can also be achieved by setting a spring between the limit column 242 and the limit plate 244. The bottom end of the limit column 242 (located below the center axis 243) abuts against the limit portion under the action of the spring to achieve rotational limit; when the trolley 100 contacts the top end of the limit column 242 (located above the center axis 243) and overcomes the elastic force of the spring, the limit column 242 rotates and closes the limit, so that the trolley 100 can be smoothly moved into the first fixed transfer seat. When the trolley 100 is separated from the limit column 242, the limit column 242 is reset to the open limit state again under the action of the spring.

[0097] In the preferred embodiment, the one-way limiting device 24 is detachably connected to the transfer bottom beam 21, so that the first fixed transfer seat and the second fixed transfer seat can be switched. Alternatively, the limiting plate 244 is detachably connected to the limiting seat 241, and the limiting column 242 can rotate freely around the central axis 243, so that the first fixed transfer seat and the second transfer seat can be switched. Then, the position and number of the second fixed transfer seats can be flexibly set by setting the one-way limiting device 24 to meet the efficiency requirements of the T-beam web production line.

[0098] The present invention also provides a T-beam web trolley storage and transportation method, using the T-beam web trolley storage and transportation system, combined with Fig.11 The storage and transportation method of the T-beam web trolley includes the following steps:

[0099] A plurality of unloaded or loaded pallet vehicles 100 are arranged on the fixed transfer seat 2;

[0100] The first switching mechanism 3 transfers the empty pallet 100 on the fixed transfer seat 2 to the material receiving mobile structure, and the empty pallet 100 is moved and loaded on the material receiving mobile mechanism 1 to obtain the loaded pallet 100; the first switching mechanism 3 transfers the loaded pallet 100 from the material receiving mobile mechanism 1 to the fixed transfer seat 2;

[0101] The second switching mechanism 4 moves the loaded trolley 100 out of the fixed transfer seat 2 for binding of the through-length reinforcement, and moves the empty trolley 100 into or out of the fixed transfer seat 2.

[0102] In some embodiments, the unloaded pallet trolley 100 on the first fixed transfer seat is transferred to the second fixed transfer seat through the second switching mechanism 4, and then transferred to the material receiving and moving mechanism 1 through the first switching mechanism 3.

[0103] The storage and transportation method of the T-beam web trolley is described below with a specific embodiment:

[0104] Set up two groups of pallet vehicles 100, A and B, each group has eight pallet vehicles 100, Fig.11 Taking group A as an example, the T-beam web pallet storage and conveying system includes five fixed transfer seats 2, of which the upper four are first fixed transfer seats and the lower one is a second fixed transfer seat. Each group of pallet trolleys 100 is divided into two sections and stored in parallel on two first fixed transfer seats, shortening the overall layout length of the production line and saving space.

[0105] Taking group A as an example, at the beginning, eight empty pallet vehicles 100 are sequentially stored on the first fixed transfer seat. Fig.11The hollow letters represent the empty pallet 100, and the solid letters represent the pallet 100 after loading. When the eight pallets B1-B8 of group B are transferred to the next station for the through-rebar binding process, the eight pallets A1-A8 of group A start to receive and transfer materials:

[0106] First, the empty pallet trolley A1 is passed into the second switching mechanism 4 on the right, and the second switching mechanism 4 transfers the empty pallet trolley A1 to the second fixed transfer seat below. After continuing to be driven and moved on the second fixed transfer seat, it is connected by the first switching mechanism 3 and transferred to the material receiving mobile mechanism 1 for material receiving.

[0107] After the material is received, the loaded pallet trolley A1 is transferred to the first fixed transfer seat of the second row through the first switching mechanism 3. At the same time, the first fixed transfer seat of the second row transfers the empty pallet trolley A2 to the second switching mechanism 4 on the right, completing a cycle.

[0108] By analogy, on the first fixed transfer seat in the second row, from left to right, are the pallet trolleys A4, A3, A2, and A1 after loading. In this way, when group B completes the next process and is transferred back to the first fixed transfer seats in the third and fourth rows, the pallet trolley 100 of group A can be transferred to the next workstation in sequence.

[0109] From this, it can be understood that when Group B is performing full-length reinforcement binding at the next workstation, Group A is loading the steel skeleton single piece 200, and then alternately cycles with Group B, thereby achieving synchronization of the loading process and the full-length reinforcement binding process, which in turn helps to improve the production efficiency of the T-beam web.

For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention.
