Description

Technical Field

[0001] The utility model relates to the technical field of building brick turning devices, and particularly relates to a brick turning machine. Background Art

[0002] During the production and preparation of bricks and tiles, after being cut into corresponding brick blanks by a brick cutting machine, corresponding brick turning operations need to be carried out to disperse several adjacent brick blanks, so as to facilitate subsequent transportation onto a conveyor belt and enter the next process.

[0003] In the prior art, in order to achieve rapid brick turning and reduce the rejection rate, there is a patent application document with a publication number of: CN103863949B and a name of gantry brick turning machine and its brick turning method. In this document, by arranging a plurality of sliding splint groups on a gantry, after moving the brick blanks a certain distance, the turning cylinders in the splint groups are used to achieve angle turning.

[0004] However, during use, the above-mentioned application document still has the following deficiencies:

[0005] 1. Since a gantry is used as a support member, it occupies a relatively large site position. Generally, the gantry is fixedly installed on the ground. If the position of the production line is adjusted, the entire gantry needs to be disassembled and assembled before it can be moved, and the operation is relatively difficult.

[0006] 2. Since the cross beam of the gantry is generally an I-beam, and the width of the I-beam is relatively narrow. In the above-mentioned patent application document, limited by the width, only one row of brick blanks can be clamped and turned at a time, while the brick cutting machine can cut multiple rows at a time. Therefore, during the transportation process, generally an additional auxiliary transportation device needs to be matched, and the efficiency is low.

[0007] 3. In the existing brick blank production line, the moving direction of the brick blanks is generally the same as the separating direction. Using the above-mentioned application document, it is very difficult for the gantry to span the entire conveyor belt. Therefore, the direction of blank separation is perpendicular to the moving direction of the brick blanks, and an additional transfer mechanism needs to be added, which will greatly increase the cost.

[0008] 4. Since the way of separating the brick blanks is achieved by a left and right translation cylinder pushing a connecting rod, and the splint group is also slidably connected to a linear guide rail. In order to avoid jerks, there are relatively high requirements for the installation accuracy, and the maintenance cost is also relatively high. Content of the Utility Model

[0009] To overcome the above defects, the purpose of the utility model is to provide a brick turning machine, which uses a synchronous belt as a traction device to drive the movement of the brick clamping unit, expands the brick turning distance, reduces the cost and improves the working stability of the equipment.

[0010] To achieve the above object, the utility model provides a brick turning machine, comprising a support seat and a plurality of brick clamping units; a articulated arm robot is connected to the top of the support seat; two blank dividing power cylinders are arranged oppositely in the middle of the support seat; a traction belt is fixedly arranged between adjacent two brick clamping units, and rigid push rods are respectively arranged on both sides of each brick clamping unit; the telescopic rods of the two blank dividing power cylinders are respectively hinged to the brick clamping units at the ends; fixed guide rails are respectively arranged on both sides along the length direction of the synchronous belt connecting and supporting the seat, and the tops of each brick clamping unit are respectively slidably connected to the fixed guide rails through a guide bearing assembly seat; a synchronous belt pulley is arranged at the end of the support seat, and synchronous belts are respectively wound on the synchronous belt pulleys; the brick clamping unit at the end is fixedly connected to the synchronous belt through the synchronous belt connecting and supporting the seat, and an avoidance hole is further arranged on the synchronous belt connecting and supporting the seat.

[0011] Preferably, the clamping mechanism comprises a first clamping plate and a second clamping plate. The first clamping plate is fixedly connected to the support seat. The upper end of the second clamping plate is connected with a cross beam through a sliding seat. A clamping cylinder is arranged between the first clamping plate and the second clamping plate. The telescopic rod of the clamping cylinder is connected to the second clamping plate, and a brick turning mechanism is further arranged on the outer side of the first clamping plate.

[0012] Preferably, the brick turning mechanism comprises two oppositely arranged brick turning shafts. A brick turning cylinder is further arranged on the outer side of the first clamping plate. A brick turning rotating plate is fixedly arranged on the brick turning shaft, and the telescopic rod of the brick turning cylinder is hinged to the brick turning shaft.

[0013] Preferably, the rigid push rod comprises a fixed seat and a limit bolt, and the limit bolt is fixedly connected to the fixed seat through a tightening thread.

[0014] Preferably, a middle baffle for limiting the moving distance of the brick clamping unit is further arranged in the middle of the support seat.

[0015] After adopting the above technical solution, the beneficial technical effects obtained by the utility model are as follows:

[0016] 1. Since an articulated arm robot is connected to the top of the support seat, the elevation and lowering of the support seat and a plurality of brick clamping units are realized through the articulated arm robot, the occupied volume is smaller, the articulated arm robot is easy to install and has a wider working range, so it can be adapted to conveyor belts of various specifications and is more convenient for regularizing, blank dividing / aligning joints and handling brick blanks.

[0017] 2. Since fixed guide rails are respectively provided on both sides along the length direction of the synchronous belt connection support base, the tops of each blank clamping unit are respectively slidably connected to the fixed guide rails through at least two guide bearing assembly seats. The guide bearings of the guide bearing assembly seats have stronger bearing capacity and lower installation accuracy than linear guide rails. When the blank separating power cylinder drives multiple blank clamping units to move along the fixed guide rails, it can not only avoid the phenomenon of jerks, but also have a longer span, and is more suitable for regularizing brick blanks with larger volumes.

[0018] 3. Since fixed guide rails are respectively provided on both sides along the length direction of the synchronous belt connection support base, the tops of each blank clamping unit are respectively slidably connected to the fixed guide rails through guide bearing assembly seats; synchronous belt pulleys are provided at the ends of the support base, and synchronous belts are respectively wound around the synchronous belt pulleys; the blank clamping units at the ends are fixedly connected to the synchronous belts through the synchronous belt connection support base, and avoidance holes are also provided on the synchronous belt connection support base. After the synchronous belt pulleys and synchronous belts are provided, the width distance between the relatively arranged first clamping plate and the second clamping plate can be larger and more stable. Therefore, when in use, at least two groups of brick blanks can be clamped and flipped simultaneously, and the efficiency is higher.

[0019] 4. Since the blank clamping units at the ends are fixed to the synchronous belts through the synchronous belt connection support base, and the synchronous belts are wound around the synchronous belt pulleys and the belts are in a ring shape, and the movement directions of the upper half and the lower half are opposite. Therefore, after the two synchronous belt connection support bases located on the same synchronous belt are respectively fixedly connected, when the synchronous belt moves, the movement consistency of the blank clamping units on both sides can be ensured, and it is easier to control.

[0031] In order to make the purpose, technical solution and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0032] See Figures 1 - 3 , the present utility model provides a brick turning machine, including a support base 1 and a plurality of brick clamping units 2; a robotic arm (not shown in the figure) is connected to the top of the support base 1; the robotic arm is a mature existing technology, occupying less space and can be directly connected to the support base 1 for the overall transfer of the brick blank. At this time, the present utility model serves as a mechanical gripper of the robotic arm to transfer the brick blank to the conveyor belt. Two blanking power cylinders 11 are arranged opposite to each other in the middle of the support base 1; a traction belt 26 is fixedly arranged between adjacent brick clamping units 2, and rigid push rods are arranged on both sides of each brick clamping unit 2; the blanking unit has two working states, blanking or joint alignment.

[0033] Blanking state, see Figure 4 , when blanking, the blanking units are basically attached together. When each brick clamping unit 2 clamps a certain number of brick blanks, and then under the action of the telescopic rods of the two blanking power cylinders 11, it moves to both sides. The adjacent blanking units are connected by a flexible traction belt 26. When the traction belt 26 is straightened, it will drag the adjacent brick clamping units 2 level by level. The two blanking units on both sides move synchronously. The final state is as shown in Figure 1 , at this time, the distances between all the brick clamping units 2 are the same, and they all move along the fixed guide rail 12 to the designated position. Since the brick blank is clamped and fixed in the middle, blanking is achieved. Since the thickness of the traction belt 26 is relatively thin and it has a certain flexibility, it is not shown in some of the drawings to avoid interference.

[0034] The butting state is exactly the opposite of the above process. The power still comes from the billet splitting power cylinder 11. At this time, the billet splitting power cylinder 11 retracts, driving the cross beam 44 to move inwards. At this time, when the billet clamping units 2 at the ends move towards the middle of the support base 1, the limit bolts 21 in each billet clamping unit 2 touch each other and push against the adjacent billet clamping unit 2, pushing level by level until there is no gap between the brick billets clamped by all the billet clamping units 2, completing the butting. The final position is as Figure 4 shown.

[0035] See Figures 5 - 6 , fixed guide rails 12 are respectively arranged on both sides along the length direction of the synchronous belt connection support base 25. The tops of each billet clamping unit 2 are respectively slidably connected to the fixed guide rails 12 through guide bearing assembly seats 22; the guide bearing assembly seats 22 are prior art, and their shape is similar to the hanging support of a glass curtain wall. Generally, there are two groups of rollers at the upper part. The fixed guide rail 12 is placed between the two groups of rollers, and the lower seat body is fixed to the cross beam 44 for supporting and driving the cross beam 44 to move. Synchronous belt wheels 23 are arranged at the ends of the support base 1, and synchronous belts 24 are respectively wound around the synchronous belt wheels 23; the billet clamping units 2 at the ends are fixedly connected to the synchronous belts 24 through the synchronous belt connection support base 25, and the synchronous belt connection support base 25 is also provided with avoidance holes. The two support bases 1 along the length direction of the support base 1 should be fixedly connected to the same synchronous belt 24. One is fixedly connected to the upper half of the synchronous belt 24, and the other synchronous belt connection support base 25 is fixedly connected to the lower half of the synchronous belt 24. In this way, when the synchronous belt 24 moves under the action of the power of the billet splitting power cylinder 11, the moving directions of the two synchronous belt connection support bases 25 are exactly the same. Both synchronous belts 24 are wound around the synchronous belt wheels 23, and an avoidance hole needs to be arranged in the middle of one of the synchronous belt connection support bases 25 for penetrating the synchronous belt 24 to ensure the synchronism of the movement.

[0036] A clamping mechanism 4 is arranged in the billet clamping unit 2 of the present utility model. The clamping mechanism 4 includes a first clamping plate 42 and a second clamping plate 43. The first clamping plate 42 is fixedly connected to the support base 1. The upper end of the second clamping plate 43 is connected to the cross beam 44 through a sliding seat. A clamping cylinder 41 is arranged between the first clamping plate 42 and the second clamping plate 43. The telescopic rod of the clamping cylinder 41 is connected to the second clamping plate 43, and a billet turning mechanism 3 is also arranged outside the first clamping plate 42. There are many ways to clamp and fix the brick billets. For the convenience of installation and control, generally, the clamping cylinder 41 can be selected. The first clamping plate 42 is fixed, and the second clamping plate 43 slides along the cross beam 44 through the sliding seat. The second clamping plate 43 approaches the first clamping plate 42 to realize the clamping and fixing of the middle brick billet. In the attached drawings, the top of the support base 1 is provided with a plurality of electromagnetic control valves for connecting a plurality of cylinders to a power control system.

[0037] The brick overturning mechanism 3 of the present utility model includes two relatively arranged brick overturning shafts 32. An overturning cylinder 31 is further provided on the outer side of the first clamping plate 42. The brick overturning shaft 32 is fixedly provided with a brick overturning rotating plate 33, and the telescopic rod of the overturning cylinder 31 is hinged to the brick overturning shaft 32. The overturning cylinder 31 is generally also a cylinder and is located on the outer side of the first clamping plate 42. The first clamping plate 42 is fixed. The brick overturning shaft 32 is connected through the brick overturning rotating plate 33. The brick blank is clamped between the two brick overturning shafts 32. Under the action of the overturning cylinder 31, the brick overturning rotating plate 33 drives the brick overturning shaft 32 to rotate a certain angle to realize brick overturning.

[0038] The rigid push rod of the present utility model includes a fixed seat and a limit bolt 21. The limit bolt 21 is fixedly connected to the fixed seat by screwing the thread. The extending distance of the limit bolt 21 can be adjusted, which is mainly used to adjust the gap between the brick blanks to keep the consistency of the spacing.

[0039] In the middle of the support seat 1 of the present utility model, a middle baffle for limiting the moving distance of the blank clamping unit 2 is further provided. The middle baffle is fixedly connected to the support seat 1 and is used to limit the moving distance of the two innermost blank clamping units 2.

[0040] Certainly, the present utility model can also have many other embodiments. Without departing from the spirit and essence of the present utility model, those skilled in the art can make various corresponding changes and deformations according to the present utility model. However, these corresponding changes and deformations should all fall within the protection scope of the appended claims of the present utility model.
