In the manufacturing process of ceramic tiles, in order to facilitate the packing and transportation of ceramic tiles, the production of ceramic tiles needs to be automated. The existing ceramic tile production lines generally adopt a single-line transportation method, with limited types of transferred ceramic tiles and low efficiency of split-flow transportation. Some processes require manual assistance and are not suitable for automatic production. The ceramic tile stacking system includes a stacking device, a flipping device, and a conveying device; the stacking device includes a track, a powered cart, an auxiliary cart, a supporting component, and a bundling component; the flipping device is located at the end of the track, and the flipping device includes a flipping unit and a delivery unit; the second bearing surface is provided with a second locking component; the delivery unit is located on one side of the semi-circular roller barrel, and the delivery unit includes a delivery component and a separating component; the conveying device is located at the end of the flipping device away from the track; the conveying device includes a conveying component, a second driving component, a frame, and a rectifying unit. This ceramic tile stacking system can only perform the packing process and automatic bundling for a single or two ceramic tile stacks, and cannot be compatible with the bundling of multiple tile stacks at the same time. Its tile bracket cannot circulate back, and there is no splitting and temporary storage function for the tile stacks with or without a frame for packing, resulting in low efficiency in handling ceramic tile stacks. Summary of the Invention

[0003] The object of the present invention is to provide a stacking, bundling and conveying system, which solves the problems that the existing stacking, bundling and conveying system cannot split and temporarily store different types of tile stacks and the bracket cannot be recycled.

[0015] The beneficial effects of the present invention are as follows:

[0016] (1) An automatic bagging device, a multi-station conveying device, a double-through-sword strapping device and a turnover device are provided on the stacking and strapping conveying system. The multi-station conveying device combines the automatic bagging device, the double-through-sword strapping device and the turnover device, enabling the brick stacks to be shunted, temporarily stored and conveyed through the multi-station conveying device, so that some brick stacks to be strapped are strapped, some brick stacks to be turned are reoriented, and the directly output brick stacks are quickly conveyed outwards. An omnidirectional conveyor and multiple conveying units are provided on the multi-station conveying unit, which can transport the brick stacks to the strapping machine for strapping and also convey the bracket back, completing the recycling of the bracket. Among them, multiple conveying units can cache a certain amount of brick stacks, increasing the capacity of receiving brick stacks and enhancing the efficiency of the entire brick-making line. In addition, there is a material distribution and transfer unit that can shunt and temporarily store the brick stacks, preventing blockage of the conveying channel and improving the conveying efficiency of the brick stacks and the brackets.

[0017] (2) A double-through-sword strapping device is provided on the stacking and strapping conveying system. The double-through-sword strapping device includes a gantry, an automatic strapping head, a right-through-sword assembly and a left-through-sword assembly. The brick stack is strapped and packed by the automatic strapping head under the gantry. The omnidirectional conveyor is exactly under the gantry. By rotating the brick stack through the omnidirectional conveying device, the packing direction of the brick stack can be adjusted to achieve multi-directional strapping of the brick stack. In addition, its right-through-sword assembly and left-through-sword assembly move inwards and outwards towards the center, which can convey the belt and pack the brick stacks to be strapped. For the brick stacks that do not need to be strapped but need to be turned over, they are directly let through, and for the brick stacks that only need to be strapped, they are strapped and then withdrawn, meeting the packing requirements for different brick stacks, reducing the repeated layout of equipment and improving the utilization efficiency of the site.

[0018] (3) The double-through-sword strapping device on the stacking and strapping conveying system includes left and right through-sword assemblies. The basic structures of the left and right through-sword assemblies are the same. They adopt a linear drive to push the gear-rack mechanism to act, and then drive the sprocket chain to push the lower belt-passing groove to complete the docking action, enabling the packing belt passing through the gantry to smoothly surround the brick stack. The actions of the left and right through-sword assemblies are rapid and accurate, and can quickly complete the belt-conveying action.

[0019] (4) The turnover device of the stacking and strapping conveying system includes a turnover frame and two conveying chains vertically arranged on the turnover frame. The turnover frame is semi-circular and is placed in a centerless rotation manner, guided by the grooved pulleys installed on both sides of the turnover frame. The two conveying chains are used for incoming and outgoing stacks, enabling the completed brick stack to be reoriented under the protection of the turnover frame, with high safety for the rotation of the brick stack.

The limit switch 441 is arranged on the side of the turnover frame 44. The sprocket 442 is rotatably connected to the base 41 and is in rolling cooperation with the turnover frame 44. The third driver 45 is composed of a reduction motor and a chain. The chain rotates in a loop below the turnover frame 44. Chain teeth are installed on the arc-shaped outer wall of the turnover frame 44. The chain cooperates with the chain teeth to push the turnover frame 44 to rotate, realizing the turnover action of the stack.

[0060] Preferably, it further includes a bracket 25. The bracket 25 can move on the multi-station conveying device 2 and is used for reciprocally transporting the brick stack. The bracket 25 is arranged in an L shape, and the bottom edge of the bracket 25 is inclined to the ground.

[0061] See Figure 21 , the working process of the stack bundling and conveying system is as follows:

[0062] The brick stack 1001 is grabbed by the manipulator 11, which slides on the track 13. The control system identifies the conveying unit 21 with an empty space, and the manipulator 11 places the brick stack 1001 on the bracket 25. The bracket 25 is driven by the material transfer chain 212 of the conveying unit 21 and moves into the feeding channel 22. When entering the roller 213, the jacking device 214 lifts the bracket 25 so that the bracket 25 and the brick stack 1001 are smoothly moved by the material transfer chain. The left and right piercing sword assemblies 33 and 34 are closed after the brick stack 1001 enters the packaging position, and then the automatic tying head 32 moves the strapping belt 1002 along the belt groove 31. 1. The first belt threading groove 336 and the second belt threading groove 346 wrap the brick stack 1001, and finally the automatic strapping head 32 tightens and fixes it. After the packaging is completed, for the brick stack 1001 that needs to be turned over, the omnidirectional conveyor 24 transports it to the turning device 4 for turning over. For some brick stacks 1001 that do not need to be turned over, the omnidirectional conveyor 24 turns and aligns the feeding channel 22 to convey them to the material distribution and transfer unit 23, and the material distribution and transfer unit 23 transports them to the lower material port. Some brick stacks 1001 that need to be turned over are sent to the turning frame 44 through the first conveying chain 42, and the turning frame 44 rotates a certain angle so that the brick stack 1001 falls on the second conveying chain 43 under the action of gravity, and is sent out by the second conveying chain 43 and taken away by external logistics equipment. The bracket 25 is sent back by the reset turning frame 44. For some brick stacks 1001 that do not need to be tied and turned over, they are directly transported outward by the material distribution and transfer unit 23.

[0063] Embodiment 2

[0064] like Figure 21 As shown, the same features as those in Example 1 are no longer repeated, and the difference lies in that: both ends of the multi-station conveying device 2 are equipped with material distribution and transfer units 23, each of which is connected to an independent double-sword bundling device 3. After being bundled by the double-sword bundling device 3, the brick stack 1001 is transported to the flipping device 4 for reversing, and the feeding channel 22 can realize multi-directional diversion of the brick stack 1001 to the conveying brick stacks 1001 at both ends, further improving the temporary storage capacity and transfer and conveying efficiency of the stacking and bundling conveying system, and one end of the material distribution and transfer unit 23 is a material discharge port, which can be connected to external logistics equipment to realize external transportation of the brick stack 1001.
