Description

Background Technology

[0001] The large-scale production of architectural ceramic tiles has a history of over a century, during which technology has continuously advanced. For large-format ceramic tiles, the entire production process has well-established mechanized operation plans. However, for small-format tiles, such as 100x100, 100x200, and 150x150mm, the picking and stacking of tiles after they exit the kiln currently must be done manually. No machine can currently handle this task because the number of small-format tiles exiting the kiln is particularly large, the speed is fast, and the arrangement is irregular. The single-tile grabbing or suction nozzle picking methods widely used for large tiles are not applicable here. Therefore, small tiles still must be picked up one by one by workers in high-temperature and harsh environments, making the work extremely arduous.

[0002] To completely change this situation, I invented a high-speed integrated brick picking and stacking machine with alternating lifting and lowering mechanisms. It can pick up and stack ceramic bricks neatly at high speed. No matter how fast or how many bricks are produced from the kiln, this small machine can easily handle the task. Summary of the Invention

[0003] For ease of explanation, the term "brick stacking machine" will be used below to refer to "interlocking alternating lifting ultra-high speed brick stacking machine".

[0004] The brick stacking machine consists of three main parts: a brick-flying system, a brick-catching system, and a brick-moving system. The brick-flying system is responsible for neatly arranging the bricks coming from the kiln and quickly throwing them off the kiln roller table. The brick-catching system catches the incoming bricks and stacks them neatly. The brick-moving system transfers the stacked bricks to a designated location. All three systems can efficiently complete the entire brick-picking and stacking task with minimal workload. Attached Figure Description

[0006] The following is a detailed explanation with reference to the accompanying drawings. For simplicity, the term "brick stacking machine" will be used in the following description to refer to the "linked lifting ultra-high-speed brick picking and stacking machine".

[0007] like Figure 1 , Figure 2 , Figure 3 , Figure 5 The brick stacking machine consists of three main parts: the brick-flying system 1, the brick-receiving system 2, and the brick-moving system 3. The brick-flying system 1 is responsible for arranging the bricks coming out of the kiln neatly and quickly throwing them away from the high-speed roller table 11. The brick-receiving system 2 is responsible for catching the incoming bricks 15 and stacking them neatly. The brick-moving system 3 is responsible for transferring the stacked bricks to a designated location.

[0008] like Figure 2 The brick-flying system includes a high-speed roller table 11, a front brick-blocking plate 12, a rear brick-blocking plate 13, a brick-flying belt 14, and bricks 15. Its operation is as follows: when the first row of bricks 15 passes the front brick-blocking plate 12, the front brick-blocking plate 12 quickly rises to prevent subsequent bricks from entering the brick-flying area; then the brick-flying belt 14 quickly rises to lift the first row of bricks 15 away from the high-speed roller table 11; subsequently, the brick-flying belt 14 rotates rapidly, causing the entire row of bricks 15 to fly laterally away from the high-speed roller table 11 area at a relatively high speed; these flying bricks 15 will then enter the next stage of the brick-receiving system 2.

[0009] like Figure 3 The brick receiving system 2 includes a brick receiving frame 21, a brick receiving box 22, a brick guide plate 23, a brick guide plate motor 24, and a photoelectric tube 25. For example... Figure 4 The working process of the brick receiving system 2 is as follows: After the first brick 15 from the flying brick system 1 enters the brick receiving box 22, the inclined brick guide plate 23 will guide the left end of the brick 15 along the left inner wall of the brick receiving box 22 and land on the left brick receiving plate 36 (see...). Figure 5When phototube 25 detects that the first brick is blocking the light, it immediately notifies the brick guide plate motor 24 to start, rotating the brick guide plate 23 to fit tightly against the right inner wall of the brick receiving box 22. The right end of the first brick 15 then falls onto the right brick receiving plate 36; the subsequent bricks 15 will then be neatly stacked one after another on top of the first brick. The subsequent work is completed by the brick moving system 3.

[0010] like Figure 5 , Figure 6 The brick-moving system 3 includes a base plate 31, a lifting unit 32, a central connecting rod 33, a drive rod 34, a lifting motor 35, a brick receiving plate 36, a solenoid valve 37, and a brick-moving belt 38. A row of bricks 15 continuously enters the brick receiving box 22 and immediately stacks on top of two brick receiving plates 36. During the formation of the brick stack, the lifting motor 35 also starts, causing the left lifting frame 32A, along with the brick stack, to descend at a set speed. Simultaneously, the right lifting frame 32B also rises. Once the first row of bricks 15 is stacked, the bottom of the brick stack is very close to the upper surface of the brick-moving conveyor belt 38. The left lifting frame 32A continues to descend until the brick stack is completely lifted away from the brick receiving plate 36 by the brick-moving conveyor belt 38. At this time, the solenoid valve 37 under the brick receiving plate 36 of the left lifting frame 32A quickly actuates, pushing the two brick receiving plates 36 to expand outward rapidly. At the same time, the solenoid valve 37 of the right lifting frame 32B also quickly actuates, pushing the other two brick receiving plates 36 to retract inward rapidly to the bottom of the brick receiving box 22, ready to receive bricks. Thus, the next round of brick flying, brick receiving, and brick moving begins, and so on, continuously collecting, stacking, and transferring all the bricks produced from the kiln to the designated location.

[0011] from Figure 7 As can be seen, when the two mating brick plates 36 of the left lifting frame 32A and the right lifting frame 32B are in the intersecting state, they will not touch each other, because the states of the two mating brick plates 36 are always opposite. That is, if one pair is in the outward-opening state, the other pair must be in the inward-retracting state, and they are always staggered.

[0012] Beneficial effects From the above description, we can see that the brick stacking machine has the following outstanding advantages: The efficiency is extremely high. As you can see, this solution doesn't require picking up bricks one by one from the kiln; instead, an entire row of bricks is carried away and collected into the box in a single, instantaneous process. Simultaneously, the brick stack descends towards the brick-moving conveyor belt 38. Once the brick-receiving box 22 has received the entire row, the bottom of the stack is already very close to the top surface of the conveyor belt 38. A short descent completes the previous stacking and allows the next round of work to begin. There is virtually no pause between the two stacking actions. This method far surpasses the efficiency of any other existing brick-picking and stacking method in the world.

[0013] Extremely low energy consumption: a) A single rotation of the brick-flying conveyor belt 14 is sufficient to collect an entire row of bricks, far more energy-efficient than picking up individual bricks mechanically or using a suction nozzle to lift them elsewhere; b) Simply extend the brick-receiving plate 36 to support the falling bricks, utilizing their own weight to lower them, allowing the brick stack to detach from the brick-receiving box 22 and enter the working surface of the brick-moving conveyor belt 38, requiring no additional machinery or movement; c) As the brick stack descends, another brick-receiving plate 36 automatically rises, requiring no additional lifting energy. This design, utilizing the weight of the bricks for work, is extremely ingenious, both energy-saving and highly efficient; d) The lifting motor 35 primarily controls the speed, consuming very little energy.

[0014] The mechanism is simple and compact. The main components are a few linkage arms, four brick-receiving plates 36, and four solenoid valves 37 – extremely simple components. Control is also very simple, relying on phototubes to control the start and stop of the brick-receiving plate motor 24 and the lifting motor 35. This simple mechanism offers higher reliability and is easier to maintain; basically, it only requires periodic lubrication.

[0015] The specifications are easy to adjust. When it is necessary to adjust the specifications of the bricks, it is only necessary to adjust the size of the brick receiving box 22 and the distance between the front and rear halves of the lifting unit 32, which is very simple and easy.

[0016] High reliability and low error rate. In particular, the linkage lifting mechanism of the lifting unit 32 only requires two central connecting rods 33 to pivotally connect the left lifting unit 32A and the right lifting unit 32B, so that one lifting motor 35 can simultaneously drive the synchronous lifting of the two mating brick plates 6. This linkage is not only simple, but also extremely reliable, with virtually no possibility of error; these components only need to perform low-speed movements, making them extremely difficult to wear, so the entire system is durable.

[0017] The directional terms used in this document, such as "front," "rear," "left," and "right," are determined based on the reader's line of sight. The component names used in this document are also designed for easy understanding by the average reader and should be identified in conjunction with the accompanying drawings. The technical features and scope of protection of this solution shall be determined by the claims.

Brick receiving plate 36, solenoid valve 37, brick moving belt 38; The lifting motor 35 drives the drive rod 34 to rotate and periodically change direction, thereby realizing the alternating rise and fall of the brick receiving plates 36 of the left lifting frame 32A and the right lifting frame 32B. When the lifting unit 32 rises to the highest point, the solenoid valve 37 controls the raised brick receiving plate 36 to retract inward to start receiving bricks from above. When the lifting unit 32 falls to the lowest point and the brick stack has contacted the upper surface of the brick moving belt 38, the solenoid valve 37 controls the low-point brick receiving plate 36 to quickly expand outward and withdraw from the brick stack area, and then start to rise to prepare for the next brick receiving.

2. According to claim 1, it is characterized by: Each of the lifting units 32 includes two equal parallelogram frames 321, which are stacked vertically and joined together by a common central rod 322. The common central rod 322 has a central groove 323 in the middle. Each of the two adjacent sides of each parallelogram frame 321 is also connected to a symmetrical sliding rod 324. The two symmetrical sliding rods 324 are identical, with one end of the sliding rod 324 being equidistant from the joint point of the parallelogram frame 321 to one end of the common central rod 322, and the other end being pivotally connected together by a pivot 325. The pivot 325 passes through the central groove 323 of the common central rod 322 and can slide back and forth along the central groove 323.

3. According to claim 1, it is characterized by: After numerous bricks 15 emerge from the kiln, the first row enters the high-speed roller table 11. The high-speed roller table 11 drives the front row of bricks 15 forward rapidly, where they are blocked by the rear brick baffle 13, thus forming a neat front row. At this time, the front brick baffle 12 quickly rises to prevent the second row of bricks 15 from entering the high-speed roller table. During this period, the brick-flying belt 14 quickly rises and rotates, flying the first row of bricks 15 laterally into the brick-receiving box 22. After the brick-flying is completed, the brick-flying belt 14 quickly descends and resets to welcome the next row of bricks. Subsequently, the front brick baffle 12 quickly descends and resets, and the second row of bricks 15 enters the high-speed roller table 11, beginning the next round of brick-flying and brick-receiving actions.

4. According to claim 1, it is characterized by: When the first brick 15 of the first row flies into the brick receiving box 22, the inclined brick guide plate 23 and the inner wall of the brick receiving box 22 will force the front end of the brick 15 to fall accurately onto the brick receiving plate 36 on the left. At this time, the phototube 25 senses that the first brick 15 has arrived and immediately notifies the brick guide plate motor 24 to rotate, turning the brick guide plate 23 to be close to the right wall of the brick receiving box 22, so that the right end of the first brick 15 falls onto the right brick receiving plate 36. Subsequent bricks 15 will fly into the brick receiving box 22 one after another and will be neatly stacked on top of the first brick 15.
