Description

Technical Field

[0001] This invention relates to the field of brick transport machinery, and in particular to an automatic brick-carrying system. Background Technology

[0002] The loading and unloading of finished bricks after they leave the kiln includes six steps: loading onto trucks, unloading at the storage site, stacking, loading onto trucks, unloading at the construction site, and stacking at the construction site. These six steps require a huge investment of manpower.

[0003] Patent application number 2016102877712 discloses a traveling brick-carrying machine, including a brick-carrying machine clamp, a lifting cylinder, and a horizontal moving device. The lifting cylinder drives the brick-carrying machine clamp to move up and down. The lifting cylinder is fixed on the horizontal moving device. The horizontal moving device includes a crossbeam, a longitudinal beam, and a moving motor. A transverse traveling device is provided on the crossbeam, and a mounting frame is provided on the transverse traveling device. The lifting cylinder is fixed on the mounting frame. A longitudinal traveling device is provided on the longitudinal beam, and the crossbeam is fixed on the longitudinal traveling device. The moving motor drives the transverse traveling device and the longitudinal traveling device to move.

[0004] However, the aforementioned brick-carrying machine still has its drawbacks: the traveling brick-carrying machine is manually operated via remote control to transport brick stacks from the storage area to the loading position. As the brick stacks are consumed, the traveling brick-carrying machine has to travel further and further, consuming more energy, and the transfer cycle of a single brick stack will also become longer. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic brick-carrying system that improves the efficiency of brick stack transportation.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: an automatic brick-carrying system, comprising a controller, a traveling brick-carrying machine, a brick-feeding rail located below the traveling brick-carrying machine, and a brick-feeding trolley placed on the brick-feeding rail. A pulling rail is provided inside the brick-feeding rail, and a pulling trolley is provided on the pulling rail to pull the brick-feeding trolley to slide. A photoelectric sensor is provided on the brick-feeding rail located below the traveling brick-carrying machine. A sensor plate is provided on the brick-feeding trolley to move and block the photoelectric sensor. The controller is connected to the pulling trolley and the photoelectric sensor.

[0007] By adopting the above technical solution, brick stacks are placed on a brick-carrying trolley. The pulling trolley pulls the brick-carrying trolley with the brick stacks to the bottom of the traveling brick-carrying machine. The induction plate blocks the photoelectric sensor to position the brick-carrying trolley directly under the traveling brick-carrying machine. After the traveling brick-carrying machine removes the brick stack, the pulling trolley pulls the brick-carrying trolley to the other end of the brick-carrying track. During this process, the traveling brick-carrying machine only needs to slide in the direction perpendicular to the brick-carrying track, which improves the transfer efficiency of the brick stacks.

[0008] A further configuration of the present invention is as follows: the pulling cart includes a cart body slidably connected to the pulling rail and a locking rod slidably connected to the top of the cart body; pulling sprockets are rotatably connected to both sides of the pulling rail; a pulling chain is sleeved between the two pulling sprockets; the cart body is fixed on the pulling chain; a drive motor for driving the pulling sprockets to rotate is provided at the end of the pulling rail; a locking hole for the locking rod to extend into is provided below the brick-feeding cart; and the controller is connected to the drive motor.

[0009] By adopting the above technical solution, the forward and reverse rotation of the drive motor drives the pulling car to move back and forth on the pulling track. When the pulling car moves to the bottom of the brick delivery car, the locking rod extends into the locking hole to lock the pulling car and the brick delivery car.

[0010] A further configuration of the present invention is as follows: the brick-carrying cart includes a frame and rollers rotatably connected to both sides of the frame; a placement plate is slidably connected to the frame; a locking post is connected to the bottom of the placement plate; a connecting hole for the locking post to pass through is provided on the frame; a push spring is provided between the placement plate and the frame; a first latch is fixedly connected to the bottom of the placement plate; a second latch is provided on the frame; and the push spring pushes the first latch to slide and engage with the second latch.

[0011] A further feature of the present invention is that: unlocking holes and unlocking posts are respectively provided on both sides of the frame, the unlocking holes and the unlocking posts are coaxially arranged, the second latch is slidably connected to the frame, and the frame is provided with a sliding groove for the second latch to be inserted and slid, and a locking spring is provided in the sliding groove to push the second latch to slide close to the unlocking hole and engage with the first latch. When the first latch disengages from the second latch, the pushing spring pushes the placement plate away from the frame, causing the locking post to disengage from the locking rod.

[0012] A further provision of the present invention is that a push plate and a pressure sensor located below the push plate are provided at the bottom of the slide cavity, and the pressure sensor is connected to the controller.

[0013] A further provision of the present invention includes a method for using the automatic brick-holding system, comprising the following steps:

[0014] S1: The pressure signals from the pressure sensor are categorized by control, including F0 when the placement plate is fully attached to the frame and the end of the locking rod is in contact with the end of the locking post; F1 when the placement plate is fully attached to the frame and the locking rod extends into the slide bar cavity; F2 when the second latch is engaged with the first latch and the locking rod extends into the slide bar cavity; and F3 when the second latch is disengaged from the first latch and remains stable.

[0015] S2: The stacked and packaged bricks are placed onto the placement plates of the brick delivery trucks by a traveling brick-carrying machine.

[0016] S3: The controller drives the trolley to move under the placement plate via the drive motor. When the controller detects that the pressure signal increases from F3 to F0, the controller controls the drive motor to continue rotating for T seconds, causing the pressure signal to decrease and stabilize at F1.

[0017] S4: When the controller detects that the pressure signal has decreased and stabilized at F1, the controller controls the drive motor to reverse. When the sensor plate blocks the photoelectric sensor, the controller controls the drive motor to stop.

[0018] S5: The vehicle-mounted brick-carrying machine removes the stack of bricks from the brick-carrying vehicle;

[0019] S6: When the controller detects that the pressure signal changes from F1 to F2, the controller controls the drive motor to continue rotating in the same direction as the most recent rotation.

[0020] S7: When the controller detects that the pressure signal changes from F2 to F3, the controller controls the drive motor to reverse.

[0021] S8: Repeat steps S3-S7 above.

[0022] The beneficial effects of this invention are:

[0023] 1. The trolley pulls the brick-feeding trolley to slide on the brick-feeding track and stop directly below the traveling brick-holding machine. During this process, the traveling brick-holding machine only slides in a direction perpendicular to the brick-feeding track, which improves the transfer efficiency of the brick stack.

[0024] 2. A locking rod with a pushing ramp is slidably connected to the pulling trolley. A locking hole is provided at the end of the locking pin. The locking pin automatically locks with the brick delivery trolley when the pulling trolley moves under the brick delivery trolley due to the setting of the pushing ramp, thereby realizing the rapid positioning of the pulling trolley and the brick delivery trolley.

[0025] 3. By setting the pressure signal to three types, and by configuring the cart as a frame and sliding connection between the cart and the frame's placement plate, and by locking buckle one and locking buckle two, the status of the brick-delivering cart is automatically sensed through the three types of pressure signals, further improving the transfer efficiency.

[0037] The technical solution of the present invention will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0038] Example: An automatic brick-carrying system, such as Figure 1 , Figure 2 As shown, the system includes a controller, a traveling brick-carrying machine 1, a brick-feeding rail 2 located below the traveling brick-carrying machine 1, and a brick-feeding trolley 3 placed on the brick-feeding rail 2. A pulling rail 4 is provided inside the brick-feeding rail 2, and a pulling trolley 5 is provided on the pulling rail 4 to pull the brick-feeding trolley 3 to slide. A photoelectric sensor 6 located below the traveling brick-carrying machine 1 is provided on the brick-feeding rail 2, and a sensor plate 31 that moves to block the photoelectric sensor 6 is provided on the brick-feeding trolley 3. The controller is connected to the pulling trolley 5 and the photoelectric sensor 6.

[0039] like Figure 1 , Figure 6 As shown, the pulling cart 5 includes a cart body 51, wheels rotatably connected to both sides of the cart body 51, and a locking rod 52 slidably connected to the top of the cart body 51. Pulling sprockets 53 are rotatably connected to both sides of the pulling track 4, and a pulling chain 54 is sleeved between the two pulling sprockets 53. The cart body 51 is fixed on the pulling chain 54. A drive motor for driving the pulling sprockets 53 to rotate is provided at the end of the pulling track 4. A locking hole 332 for the locking rod 52 to extend into is provided below the brick delivery cart 3. The controller is connected to the drive motor.

[0040] like Figure 6 , Figure 7 As shown, the vehicle body 51 is provided with a sliding rod cavity 511 into which the locking rod 52 extends. A lifting spring 512 is provided in the sliding rod cavity 511 to push the locking rod 52 to slide outward from the sliding rod cavity 511. A pushing inclined surface 521 is provided at the end of the locking rod 52. A locking post 331 is provided at the bottom of the brick delivery vehicle 3. The locking hole 332 is located at the bottom of the locking post 331. When the locking rod 52 approaches the locking hole 332, the end of the locking post 331 applies a pushing force to the pushing inclined surface 521 to push the locking rod 52 to slide into the sliding rod cavity 511. The brick delivery cart 3 includes a frame 32 and rollers rotatably connected to both sides of the frame 32. A placement plate 33 is slidably connected to the frame 32. A locking pin 331 is connected to the bottom of the placement plate 33. The frame 32 is provided with a connecting hole 321 for the locking pin 331 to pass through. A push spring 34 is provided between the placement plate 33 and the frame 32. A first lock 333 is fixedly connected to the bottom of the placement plate 33. A second lock 322 is provided on the frame 32. The push spring 34 pushes the first lock 333 to slide and engage with the second lock 322.

[0041] like Figure 2 , Figure 4 As shown, unlocking holes 35 and unlocking posts 36 are respectively provided on both sides of the frame 32. The unlocking holes 35 and unlocking posts 36 are coaxially arranged. Locking buckle 322 is slidably connected to the frame 32. The frame 32 is provided with a sliding groove 37 for locking buckle 322 to be inserted and slid. A locking spring 38 is provided in the sliding groove 37 to push locking buckle 322 to slide close to the unlocking hole 35 and engage with locking buckle 333. When locking buckle 333 disengages from locking buckle 322, the pushing spring 38 pushes the placement plate 33 away from the frame 32, causing locking post 331 to disengage from locking rod 52. A pushing plate 513 and a pressure sensor 514 located below the pushing plate 513 are provided at the bottom of the sliding rod cavity 511. The pressure sensor 514 is connected to the controller.

[0042] The method of using an automatic brick-laying system includes the following steps:

[0043] S1: The pressure signal of the pressure sensor 514 is classified by control, including F0 when the placement plate 33 is completely attached to the frame 32 and the end of the locking rod 52 is in contact with the end of the locking post 331; F1 when the placement plate 33 is completely attached to the frame 32 and the locking rod 52 extends into the locking hole 332; F2 when the placement plate 33 is separated from the end face of the frame 32, the second latch 322 is engaged with the first latch 333 and the locking rod 52 extends into the locking hole 332; and F3 when the position of the second latch 322 and the first latch 333 is separated from the placement plate 33 and remains stable.

[0044] S2: Multiple stacks of bricks, after being packed, are placed onto the placement plates 33 of the brick-feeding carts 3 by the overhead brick-handling machine 1. At this time, the placement plates 33 are completely in contact with the cart frame 32. Figure 2 , Figure 5 As shown;

[0045] S3: The controller drives the trolley 5 to move below the placement plate 33 via the drive motor. When the controller detects that the pressure signal increases from F3 to F0, the controller controls the drive motor to continue rotating for T seconds, causing the pressure signal to decrease and stabilize at F1. At this time, the locking rod 52 approaches the locking post 331. The end of the locking post 331 applies a pushing force to the pushing inclined surface 521, pushing the locking rod 52 to slide into the sliding rod cavity 511, so that the locking rod 52 contacts the end of the locking post 331. However, when the trolley 5 continues to move, the lifting spring 512 pushes the locking rod 52 to fully extend into the locking cavity. Figure 2 , Figure 6 As shown.

[0046] S4: When the controller detects a decrease in the pressure signal and it stabilizes at F1, the controller controls the drive motor to reverse. When the sensing plate 31 blocks the photoelectric sensor 6, the controller controls the drive motor to stop. During this process, the brick-feeding cart 3, along with the brick stack, moves directly under the cart-type brick-carrying machine. Figure 9 As shown;

[0047] S5: The car-type brick-carrying machine removes the brick stacks from the brick-carrying car 3;

[0048] S6: When the controller detects that the pressure signal changes from F1 to F2, the controller controls the drive motor to continue rotating in the same direction as the most recent rotation. During this process, the placement plate 33 loses the pressure of the brick stack, and the push spring 34 pushes the placement plate 33 away from the frame 32. Lock one 333 and lock two 322 engage, and the lifting spring 512 is initially released. Figure 3 , Figure 7 As shown;

[0049] S7: When the controller detects that the pressure signal changes from F2 to F3, the controller controls the drive motor to reverse. During this process, the unlocking pin 36 extends into the unlocking hole 35. The unlocking pin 36 pushes the second latch 322 to slide in the slide groove 37, causing the first latch 333 to disengage from the second latch 322. The end of the locking pin 331 disengages from the end of the locking rod 52, and the lifting spring 512 is further relaxed. Figure 4 , Figure 8 As shown;

[0050] S8: Repeat steps S3-S7 above.

[0051] like Figure 2 , Figure 3 As shown, a positioning frame 7 is provided at one end of the moving track where the empty brick delivery cart 3 is placed. An initial rod 71 is provided on the positioning frame 7 and extends into the unlocking hole 35. A sensing frame 8 is provided at one end of the pulling track 4 where the brick delivery cart 3 with brick stacks is placed. A limit switch 81 connected to the controller is provided on the sensing frame 8. When the first brick delivery cart 3 is delivered to the end where the empty brick delivery cart 3 is placed, the initial rod 71 extends into the unlocking hole 35 to disengage the first lock 333 and the second lock 322. When the brick stack is delivered, the pulling cart 5 slides and contacts the limit switch 81, and the controller controls the drive motor to stop moving.
