Description

Splicing conveyor line and its control method

This case is about a conveyor line, especially a splicing conveyor line and its control method

Traditional conveyor lines include belt conveyor lines, chain conveyor lines and roller conveyor lines. Among them, the belt conveyor line relies on the friction between the belt and the drive roller to perform the work. Therefore, it is generally used to transport materials of low quality, such as a large number of manual assembly lines. In addition, the chain conveyor line uses the movement of the chain and combines with other additional devices, such as hangers, hooks, and flat plates, to automatically transport materials from one location to another; it is mainly used in automated production lines and can use more accurate stepping. Conveying can also use professional blocking cylinders on the production line, so that the workpiece stays exactly where it is needed, and does not affect the continuous operation of the chain.

If the traditional conveying line needs to change the attitude and direction of conveying materials, the general methods include:

(1) The trajectory of the conveyor line is designed to be curved or inclined according to needs, so that the material changes its posture and running direction when moving along the conveyor line;

(2) Set up a blocking device on the conveyor line to change the center of gravity of the material due to collision with the blocking device during transportation, and then change the posture and direction of the material;

(3) Set up lifting, overturning, rotating and other devices to coordinate the posture and running direction of the material with the conveyor line;

(4) Set up special planes or manipulators, and cooperate with gripping fixtures to reprocess the posture and running direction of materials.

Some automated production lines often need to perform operations such as positioning, posture changing, and changing the conveying direction of materials to meet the needs of the production process. As mentioned above, the traditional method of conveying lines is generally to set up devices such as blocking, jacking, rotating, and loading to meet the demand, but first of all, it will cause the entire conveying system to be complex in structure and difficult to control. Secondly, the entire automated production line needs to be carefully planned at the design stage. The workload of processing, installation and commissioning is very huge, and it is generally difficult to change after it is officially put into production. Finally, once the traditional conveyor line fails, the maintenance time will be longer, and it will cause the production line to stop, causing economic losses.

Therefore, how to develop a splicing conveyor line with reliable connection and convenient disassembly and assembly to improve the above-mentioned lack of conventional technology is a problem that urgently needs to be solved by those in the relevant technical field.

Furthermore, power and torque are transmitted by non-contact magnetic force. Magnetic transmission has the advantages of overload protection, adjustable torque, maintenance-free, low vibration, low noise, simple isolation and sealing, and no dust accumulation. Therefore, the connection and disassembly between the passive conveying unit and the active conveying unit are very convenient and fast. And in the process of use, if one of the conveying units fails, it can be easily removed and replaced with a new conveying unit, together with other conveying units to form a new conveying line to continue to use, without the need to shut down for a long time for maintenance, effectively improving Conveying efficiency.

When the material 100 runs between the two conveying units, the second conveying roller 3 of one conveying unit rotates in the forward direction, and the second conveying roller 3 of the other conveying unit rotates in the reverse direction, so that the material 100 produces a The torque rotates until the material 100 rotates to a desired angle, the second conveying roller 3 stops moving toward each other, and the material 100 stops rotating.

As shown in FIG. 8C, the first conveying roller 2 and the second conveying roller 3 rotate simultaneously in the forward or reverse direction, so that the material 100 obtains a combined speed of the lateral and longitudinal motion speeds, and drives the material 100 into another conveying channel.

Refer to FIG. 9, which shows a schematic diagram of the principle that the material rotates on the splicing conveyor line of the present invention. As shown in Fig. 9, in the conveyor line formed by splicing the 2×4 arrangement of conveying units, the first conveying roller 2 between two adjacent conveying units rotates oppositely, or two adjacent conveying units When the second conveying roller 3 rotates in the opposite direction, the material 100 will obtain a torque when it runs between two adjacent conveying units, thereby causing the material 100 to rotate. Therefore, if the material 100 needs to be rotated, only the material 100 needs to be run to the boundary line between the conveying units, and then the two conveying units can be controlled by the control unit to rotate the horizontal rollers or the longitudinal rollers to rotate. .

On the other hand, according to the structure of the aforementioned splicing conveyor line, this case further discloses a control method of the splicing conveyor line.

According to the control method of the splicing conveyor line of the embodiment of the present disclosure, by providing the above-mentioned splicing conveyor line of the present disclosure, the material is placed on the splicing conveyor line, and a control unit is provided, and the control unit controls the operation of the splicing conveyor line, and Realize the transportation of materials.

By controlling the rotation speed and direction of the first conveying roller group and the second conveying roller group, the animal material is accelerated, decelerated, or turned.

According to an embodiment of the present disclosure, when the material is transferred between two adjacent conveying units, the first conveying roller group of the two conveying units is controlled to move toward each other, and/or the second conveying roller group of the two conveying units is controlled to move toward each other to achieve The rotation of the material realizes the transformation of posture.

According to the control method of the splicing conveyor line according to the embodiment of the present disclosure, there is no need to change the splicing conveyor line when the material needs to change the speed, and it can be achieved by controlling the rotation speed of the conveying roller group; further, when the material needs to be changed and conveyed Direction, without changing the physical hardware facilities of the splicing conveyor line, but only need to control the speed and rotation direction of the first and second conveyor roller groups; when you need to change the position of the material bit, you only need to control the two adjacent The first conveying roller group or the second conveying roller group of the conveying unit moves toward each other, and a torque can be generated to achieve rotation. The control is simple, convenient, efficient, and cost-saving.

Referring to FIG. 1A, two materials 100 separated by a gap G are conveyed and turned on the two sets of conveying rollers of the conveying line. Different trajectories and postures can be operated between different materials 100 through the control of the control unit, and the distance G between the two materials 100 can be quantitatively controlled to achieve the purpose of intelligent transportation.

For example, sometimes it is necessary to control the material 100 to be transported to different positions, and in practice, it often occurs that the material 100 in the front needs to be transferred, and the material 100 in the rear follows behind with no gap in the middle. If the traditional conveyor line is used, the transfer mechanism needs to be used to transfer the material 100, and additional material separation equipment is added to divide the front and rear materials 100 first, and then the back material 100 is stopped before the front material 100 can be normally carried out. Transfer. Through the modular splicing conveying line based on the conveying unit of the present disclosure, the speed and direction of the conveying rollers of different conveying units can be different. By controlling the speed of the conveying rollers by the control unit, the speed difference of the material 100 can be achieved, increasing The large spacing G reduces the conveyance and realizes the separation of continuous materials 100, and vice versa. In a conveying unit, the simultaneous movement of the horizontal conveying roller and the longitudinal conveying roller will produce a set of vector friction forces on the material 100. By changing the direction and speed of the conveying roller motion vector, the running speed and direction of the material 100 can be controlled . In addition, by controlling the rotation speed and direction of the rollers of adjacent conveying units, the relative movement between the lateral conveying rollers of the two adjacent conveying units, or the longitudinal motion between the longitudinal conveying rollers, the two groups of oppositely moving rollers can be achieved The wheel can generate a set of torque to the material 100, so that the material 100 rotates, and the purpose of changing the attitude of the material 100 is realized.

The splicing conveyor line of the present disclosure and its control method can be applied to various occasions, for example, in the sorting of items, the material 100 needs to be moved to a specified position in a specified posture, because the splicing conveyor line of the present disclosure has a good extension Sex and flexibility, you can quickly transfer and sort materials 100 for sorting applications. In addition, a buffer area can also be set up in the splicing conveyor line of the present disclosure. The buffer area is also constructed by the splicing of the conveying unit, which can orient, arrange and transport the material 100 to a designated location for temporary storage, when needed Then return the material 100 to the conveyor line in the specified direction and posture. On the other hand, it can also be used in smart warehousing. Since the conveying unit can be powered by magnetic drive, the non-contact characteristics of the magnetic drive ensure that the AGV trolley is used to transfer and place the conveying unit to achieve the The rapid installation makes it possible for the AGV trolley to transfer the transport unit and rebuild the transport line; in addition, the material 100 can be transported to the designated transport unit through the control of the control unit, and then passed through the unmanned guided vehicle (Automated Guided Vehicle, (AGV) pick and place the conveying unit, thus realizing the intelligent logistics system.

In summary, this case provides a splicing conveyor line with reliable connection, convenient disassembly and assembly, and its control method. The splicing conveying line is composed of multiple modular conveying units. The multiple conveying units include a passive conveying unit and an active conveying unit. When the passive conveying unit and the active conveying unit are connected by the first magnetic coupling, the A magnetic coupling transmits the driving force of the active conveying unit to the transmission mechanism of the passive conveying unit, driving the conveying roller group of the passive conveying unit to rotate. Furthermore, power and torque are transmitted by non-contact magnetic force. Magnetic transmission has the advantages of overload protection, adjustable torque, maintenance-free, low vibration, low noise, simple isolation and sealing, and no dust accumulation. Therefore, the connection and disassembly between the passive conveying unit and the active conveying unit are very convenient and fast. And in the process of use, if one of the conveying units fails, it can be easily removed and replaced with a new conveying unit, together with other conveying units to form a new conveying line to continue to use, without the need to shut down for a long time for maintenance, effectively improving Conveying efficiency.
