Description

Technical Field

[0001] This invention relates to the field of material transportation technology, and in particular to a high-efficiency conveying system and its control method. Background Technology

[0002] In factory production lines, conveyor systems are frequently used to transport materials. A conveyor system typically consists of multiple motor-driven conveyor belts that transport materials to the discharge end.

[0003] During the conveying process, in order to ensure the uniformity of material flow, the number of materials on each conveyor belt is the same. When the lengths of the conveyor belts in the conveying system are not equal, the shortest conveyor belt limits the maximum conveying capacity of the entire conveying system, resulting in relatively low conveying efficiency.

The control module is also used to control all conveyor belts to stop running when the state of the rear-end photodiode of the n-th conveyor belt is in the first state. The photodiode states include a first state and a second state, where the first state indicates material detection and the second state indicates no material detection. <n,n≥2。

The first sub-packaging phototube is located at one end of the discharge belt near the nth conveyor belt. The distance between the first sub-packaging phototube and the second sub-packaging phototube is equal to the length of the material. The control module is electrically connected to the first sub-packaging phototube and the second sub-packaging phototube respectively. The control module is used to obtain the status of the second sub-packaging phototube and, when the status of the second sub-packaging phototube and the rear phototube of the nth conveyor belt are both in the first state, control the discharge belt and each of the conveyor belts to stop running.

[0009] Optionally, a discharge phototube is provided on the discharge belt, and the discharge phototube is located at the end of the discharge belt away from the nth conveyor belt. The control module is electrically connected to the discharge phototube. The control module is also used to control the operation of the discharge belt when the state of the second sub-packaging phototube is in the first state and discharge is allowed, and to control the simultaneous operation of the feeding belt, each of the conveyor belts and the discharge belt when the state of the second sub-packaging phototube changes from the first state to the second state, and when the states of the first sub-packaging phototube and the discharge phototube are both in the second state.

[0010] Optionally, the control module is further configured to acquire the state of the feeding phototube when both the second sub-packaging phototube and the rear phototube of the nth conveyor belt are in the first state, and to control the feeding belt to continue running when the state of the feeding phototube is in the second state.

[0011] Optionally, the control module is further configured to control the m-th conveyor belt and all conveyor belts between the m-th conveyor belt and the feed belt to stop operating when the duration of the second state of both the front-end phototube and the rear-end phototube of the m-th conveyor belt is greater than a threshold time.

[0012] According to another aspect of the present invention, a control method for a high-efficiency conveying system is provided. The high-efficiency conveying system includes: a control module, a feed belt, a discharge belt, and n conveyor belts. The control module is electrically connected to the feed belt, the discharge belt, and each of the conveyor belts. The n conveyor belts are sequentially arranged between the feed belt and the discharge belt along the material transport direction. The material is transported from the feed belt to the conveyor belts. In the material transport direction, a front-end photoelectric tube and a rear-end photoelectric tube are respectively arranged at both ends of each of the conveyor belts. A feed photoelectric tube is arranged at the end of the feed belt closest to the first conveyor belt. The control module is electrically connected to each of the front-end photoelectric tubes, each of the rear-end photoelectric tubes, and the feed photoelectric tube.

[0013] The control method includes:

[0014] Obtain the status of each of the front-end phototubes, each of the rear-end phototubes, and the feeding phototube;

[0015] When the feed phototube is in the first state and the rear phototube of the first conveyor belt is in the second state, the feed belt is controlled to run to transport the material to the first conveyor belt;

[0016] When the state of the front-end photodiode of the m-th conveyor belt is in the first state and the state of the rear-end photodiode of the (m+1)-th conveyor belt is in the second state, the m-th conveyor belt is controlled to run.

[0017] When the photocell at the rear end of the nth conveyor belt is in the first state, all conveyor belts are stopped. The photocell's state includes a first state and a second state. The first state indicates that the photocell has detected material, and the second state indicates that the photocell has not detected material. m <n,n≥2。

[0018] Optionally, in the material transport direction, a first sub-packaging photocell and a second sub-packaging photocell are sequentially arranged on the discharge belt. The first sub-packaging photocell is located at one end of the discharge belt near the nth conveyor belt. The distance between the first sub-packaging photocell and the second sub-packaging photocell is equal to the length of the material. The control module is electrically connected to the first sub-packaging photocell and the second sub-packaging photocell respectively. After controlling all conveyor belts to stop running when the state of the rear photocell of the nth conveyor belt is in the first state, the following steps are taken:

[0019] Obtain the status of the second sub-package phototube;

[0020] When the second sub-packaging phototube and the rear phototube of the nth conveyor belt are both in the first state, the discharge belt and each of the conveyor belts are controlled to stop running.

[0021] Optionally, a discharge phototube is provided on the discharge belt, the discharge phototube is located at the end of the discharge belt away from the nth conveyor belt, and the control module is electrically connected to the discharge phototube;

[0022] When both the second sub-packaging phototube and the rear phototube of the nth conveyor belt are in the first state, the discharge belt and each of the conveyor belts are controlled to stop running. Afterwards, the process includes:

[0023] When material discharge is permitted, control the operation of the discharge belt;

[0024] When the state of the second sub-packaging phototube changes from the first state to the second state, and the states of the first sub-packaging phototube and the discharge phototube are both in the second state, the feeding belt, each of the conveyor belts and the discharge belt are controlled to operate simultaneously.

[0025] Optionally, when the second sub-packaging phototube and the rear phototube of the nth conveyor belt are both in the first state, after controlling the discharge belt and all the conveyor belts to stop running, the method further includes:

[0026] Obtain the status of the feed phototube;

[0027] When the feed phototube is in the second state, the feed belt is controlled to continue running.

[0028] Optionally, after obtaining the status of each of the front-end phototubes and the rear-end phototubes, the method further includes:

[0029] When the duration of the second state of both the front-end phototube and the rear-end phototube of the m-th conveyor belt exceeds a threshold time, the m-th conveyor belt and all conveyor belts between the m-th conveyor belt and the feed belt are controlled to stop operating.

[0030] The high-efficiency conveying system of this invention includes: a control module, a feed belt, a discharge belt, and n conveyor belts. The control module is electrically connected to the feed belt, the discharge belt, and each conveyor belt. The n conveyor belts are sequentially arranged between the feed belt and the discharge belt along the material transport direction, and the material is transported from the feed belt to the conveyor belts. In the material transport direction, a front-end photoelectric tube and a rear-end photoelectric tube are respectively installed at both ends of each conveyor belt, and a feed photoelectric tube is installed at the end of the feed belt closest to the first conveyor belt. The control module is electrically connected to each front-end photoelectric tube, each rear-end photoelectric tube, and the feed photoelectric tube. The control module is used to acquire the status of each front-end photoelectric tube, each rear-end photoelectric tube, and the feed photoelectric tube. When the feed photoelectric tube is in a first state and the rear-end photoelectric tube of the first conveyor belt is in a second state, the control module controls the feed belt to run to transport the material to the first conveyor belt. The control module controls the operation of the m-th conveyor belt to transport materials to the (m+1)-th conveyor belt when the state of the front photodiode of the m-th conveyor belt is in the first state and the state of the rear photodiode of the (m+1)-th conveyor belt is in the second state, thus realizing the sequential transportation of each material from the feed end to the n-th conveyor belt. The control module is also used to stop the conveyor belt when the state of the rear photodiode of the n-th conveyor belt is in the first state. In this embodiment, the control module acquires the states of each front and rear photodiode in real time, gradually transferring multiple materials from the feed belt to the n-th conveyor belt, ensuring that each conveyor belt is fully loaded with materials. Furthermore, each conveyor belt is loaded with materials according to its own length, without needing to maintain the same number of materials on each conveyor belt. The number of materials on each conveyor belt is not limited by the length of the shortest conveyor belt, maximizing the conveying capacity of the system.

[0039] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0040] Figure 1 This is a schematic diagram of a high-efficiency conveying system provided in an embodiment of the present invention, with reference to... Figure 1 The high-efficiency conveying system includes: control module 1, feed belt 2, discharge belt 4 and n conveyor belts 3. Control module 1 is electrically connected to feed belt 2, discharge belt 4 and each conveyor belt 3. The n conveyor belts 3 are arranged sequentially between feed belt 2 and discharge belt 4 along the material transport direction. Material 01 is transferred from feed belt 2 to conveyor belt 3.

[0041] In the material transport direction, each conveyor belt 3 is equipped with a front phototube 31 and a rear phototube 32 at both ends. The feeding belt 2 is equipped with a feeding phototube 21 at one end near the first conveyor belt. The control module 1 is electrically connected to each front phototube 31, each rear phototube 32 and the feeding phototube 21. The control module 1 is used to obtain the status of each front phototube 31, each rear phototube 32 and the feeding phototube 21. When the status of the feeding phototube 21 is the first state and the status of the rear phototube of the first conveyor belt is the second state, the feeding belt 2 is controlled to run to transport the material 01 to the first conveyor belt.

[0042] Control module 1 is used to control the operation of the m-th conveyor belt when the state of the front-end photodiode of the m-th conveyor belt is in the first state and the state of the rear-end photodiode of the (m+1)-th conveyor belt is in the second state. The control module is also used to control all conveyor belts to stop operating when the state of the rear-end photodiode 32 of the n-th conveyor belt is in the first state. The states of the photodiodes include a first state and a second state; the first state indicates that material has been detected, and the second state indicates that no material has been detected. <n,n≥2。

[0043] Specifically, each conveyor belt (feed belt 2, conveyor belt 3, or discharge belt 4) is driven by a motor and runs or stops under motor control. In this embodiment, the control module 1 is connected to the feed belt 2, each conveyor belt 3, and the discharge belt 4. Specifically, the control module 1 is connected to the motor of each conveyor belt to indirectly control each conveyor belt through the motor. The length of each conveyor belt 3 can be set according to requirements. The lengths of each conveyor belt 3 can be the same or different. This embodiment does not make a specific limitation in this regard. In the material transportation direction, a front photoelectric tube 31 and a rear photoelectric tube 32 are respectively set at both ends of each conveyor belt 3. Specifically, the front photoelectric tube 31 and the rear photoelectric tube 32 can be set at a position on the conveyor belt 3 that does not affect the transportation of material 01, or the front photoelectric tube 31 and the rear photoelectric tube 32 can be set at a position within a set distance from the conveyor belt 3 to detect whether material 01 has passed. Optionally, the distance between the feed photoelectric tube 21 and the front photoelectric tube 31 of the first conveyor belt is less than the length of the material.

[0044] Control module 1 is used to acquire the status of each front-end phototube 31, each rear-end phototube 32, and the feed phototube 21. Specifically, the high-efficiency conveying system also includes a start button. After the user presses the start button, a start command is sent to control module 1. After receiving the start command, control module 1 acquires the status of each front-end phototube 31 and rear-end phototube 32 in real time. When material 01 blocks the front-end phototube 31, the rear-end phototube 32, or the feed phototube 21, the phototube's status is in the first state. When material 01 does not block the front-end phototube 31 or the rear-end phototube 32, the phototube's status is in the second state. Thus, the presence or absence of material 01 can be determined based on the status of the front-end phototube 31 or the rear-end phototube 32.

[0045] The control module 21 is used to control the feeding belt 2 to transport material 01 to the first conveyor belt when the state of the feeding phototube 21 is in the first state and the state of the rear phototube 32 of the first conveyor belt is in the second state.

[0046] When the feed phototube 21 is in the first state, it indicates that there is material 01 at the tail end of the feed belt 2 (the end closest to the first conveyor belt). If the tail end phototube 32 of the first conveyor belt is in the second state, that is, there is no material 01 at the tail end of the first conveyor belt (the end closest to the second conveyor belt), and the first conveyor belt is not full, the control module 1 controls the feed belt 2 to run to transport another material 01 to the first conveyor belt. If the feed phototube 21 is in the first state, and the tail end phototube 32 of the first conveyor belt is in the first state, that is, the first conveyor belt is full, the control module 1 controls the feed belt 1 to stop running until the material 01 on the first conveyor belt is transported to the second conveyor belt. The tail end phototube 32 of the first conveyor belt then changes to the second state, and the control module 1 controls the feed belt 1 to run again to transport another material 01 to the first conveyor belt. It is worth noting that after the user presses the start button, the control module 1 receives the start command and controls the feed belt 2, each conveyor belt 3 and the discharge belt 4 to run at the same speed to transport material 01 to the first conveyor belt.

[0047] Control module 1 controls the operation of the m-th conveyor belt when the state of the front photodiode 31 of the m-th conveyor belt is in the first state and the state of the rear photodiode 32 of the (m+1)-th conveyor belt is in the second state. Specifically, taking m=1 as an example, when the state of the front photodiode 31 of the first conveyor belt is in the first state, it indicates that material 01 has been transported to the first conveyor belt. Control module 1 continues to acquire the state of the rear photodiode 32 of the second conveyor belt. When the state of the rear photodiode 32 of the second conveyor belt is in the second state, it indicates that the second conveyor belt is not full, and control module 1 can control the first conveyor belt to run to transport material 01 to the second conveyor belt. When the state of the rear photodiode 32 of the second conveyor belt is in the first state, it indicates that the second conveyor belt is full, and control module 1 controls the first conveyor belt to stop running until the second conveyor belt transports one piece of material 01 to the third conveyor belt. After the state of the rear photodiode 32 of the second conveyor belt changes to the second state, control module 1 can continue to control the first conveyor belt to run. Other conveyor belts follow the same principle.

[0048] The control module 1 is also used to control all conveyor belts to stop running when the state of the photoelectric tube 32 at the rear end of the nth conveyor belt is in the first state. When the state of the photoelectric tube at the rear end of the nth conveyor belt is in the first state, it indicates that the last conveyor belt is full of material. At this time, the material preparation process is over, and the operation of each conveyor belt can be stopped to wait for the subsequent discharge command.

[0049] The control module controls the operation of the m-th conveyor belt to transport materials to the (m+1)-th conveyor belt when the state of the front photodiode of the m-th conveyor belt is in the first state and the state of the rear photodiode of the (m+1)-th conveyor belt is in the second state, thus realizing the sequential transport of each material from the feed belt to the n-th conveyor belt. The control module also controls the conveyor belt to stop operating when the state of the rear photodiode of the n-th conveyor belt is in the first state. In this embodiment, the control module acquires the real-time states of each front photodiode, rear photodiode, and feed photodiode, gradually transferring multiple materials from the feed belt to the n-th conveyor belt. This ensures that each conveyor belt is fully loaded with materials, and that each conveyor belt is placed according to its own length, without needing to maintain the same number of materials on each conveyor belt. The number of materials on each conveyor belt is not limited by the length of the shortest conveyor belt, maximizing the conveying capacity of the system.

[0050] Figure 2 This is a schematic diagram of another high-efficiency conveying system provided in an embodiment of the present invention, with reference to... Figure 2 Optionally, in the material transport direction, a first sub-packaging phototube 41 and a second sub-packaging phototube 42 are sequentially installed on the discharge belt 4. The first sub-packaging phototube 41 is located at one end of the discharge belt 4 near the nth conveyor belt. The distance between the first sub-packaging phototube 41 and the second sub-packaging phototube 42 is equal to the length of the material 01. The control module 1 is electrically connected to the first sub-packaging phototube 42 and the second sub-packaging phototube 42 respectively. The control module 1 is used to obtain the state of the second sub-packaging phototube 42, and when the states of the second sub-packaging phototube 42 and the rear phototube 32 of the nth conveyor belt are both in the first state, the control module 1 controls the discharge belt 4 and each conveyor belt 3 to stop running.

[0051] When the second sub-packaging phototube 42 is in the first state, it indicates that there is already one material on the discharge belt 4. The discharge belt 4 and each conveyor belt 3 are then stopped and awaiting discharge. The length between the first sub-packaging phototube 41 and the second sub-packaging phototube 42 is equal to the length of the material 01, which ensures that only one material 01 exists on the discharge belt 4 during the discharge stage, thus ensuring orderly discharge.

[0052] Continue to refer to Figure 2 Optionally, a discharge phototube 43 is installed on the discharge belt 4. The discharge phototube 43 is located at the end of the discharge belt 4 away from the nth conveyor belt. The control module 1 is electrically connected to the discharge phototube 43. The control module 1 is also used to control the operation of the discharge belt 4 when the state of the second sub-packaging phototube 42 is in the first state and discharge is allowed, and to control the simultaneous operation of the feeding belt 2, each conveyor belt 3 and the discharge belt 4 when the state of the second sub-packaging phototube 42 changes from the first state to the second state, and the states of the first sub-packaging phototube 41 and the discharge phototube 43 are both in the second state.

[0053] The rear end of the discharge belt 4 is connected to a receiving device for receiving materials. When the material on the discharge belt 4 is transferred to the receiving device, one material 01 is discharged. After the receiving device is in position and ready to receive the relevant material 01, discharge is permitted, and a discharge command is sent to the control module 1. The control module 1 controls the discharge belt 4 to run, transporting the material 01 to the receiving device. After the material 01 is transported to the receiving device, there is no material 01 on the discharge belt 4. That is, the states of the second sub-packaging phototube 42, the first sub-packaging phototube 41, and the discharge phototube 43 are all in the second state. At this time, the feeding belt 2, each conveyor belt 3, and the discharge belt 4 are controlled to run simultaneously, pushing the material on each conveyor belt forward one step, continuing to transport the next material 01 to the receiving device.

[0054] Continue to refer to Figure 2 Optionally, the control module 1 is also used to obtain the state of the feeding phototube 21 when the states of the second sub-packaging phototube 42 and the rear phototube 32 of the nth conveyor belt are both in the first state, and to control the feeding belt 2 to continue running when the state of the feeding phototube 21 is in the second state.

[0055] When both the second sub-packaging phototube 42 and the rear phototube 32 of the nth conveyor belt are in the first state, it indicates that each conveyor belt is full and can be stopped to await material discharge. Whether the feeding belt 2 should be stopped requires further judgment. The operator places the material on the feeding belt. Due to the possible influence of other processes at the feeding end, the spacing of material 01 on the feeding belt 2 can vary. To avoid material 01 being located at the end of the feeding belt 2 furthest from the feeding phototube 21, when the state of the feeding phototube 21 is in the second state, the feeding belt 2 is controlled to continue running to transport material 01 on the feeding belt 2 to the feeding phototube 21 and then stop to await subsequent transportation instructions, thereby improving transportation efficiency and eliminating the impact of uneven material distribution on the feeding belt 2.

[0056] Continue to refer to Figure 2 Optionally, the control module is also used to control the m-th conveyor belt and each conveyor belt 3 between the m-th conveyor belt and the feed belt 2 to stop running when the duration of the second state of the front phototube 31 and the rear phototube 32 of the m-th conveyor belt is greater than a threshold time.

[0057] For example, the threshold time can be set according to requirements, such as 20 minutes. When the duration of the second state of both the front phototube 31 and the rear phototube 32 of the m-th conveyor belt is greater than the threshold time, it indicates that no material 01 has passed on the m-th conveyor belt for a period of time. That is, there is no material to be transported from the feed belt 2 to the m-th conveyor belt. The control module 1 controls the m-th conveyor belt and each conveyor belt 3 between the m-th conveyor belt and the feed belt 2 to stop running in order to reduce the power consumption of the system.

[0058] Optionally, the control module 1 is further configured to control the feeding belt 2 to stop operating when the duration of the second state of the feeding phototube 21 is greater than a threshold time. When the duration of the second state of the feeding phototube 21 is greater than the threshold time, it indicates that the feeding has reached the tail end and there is no more material 01 that can be placed on the feeding belt 2 for transportation. The control module 1 controls the feeding belt 2 to stop to reduce system power consumption. Optionally, the control module is further configured to control the feeding belt 1, each conveyor belt 3, and the discharge belt 4 to stop operating when the duration of the second state of the first sub-packaging phototube 41, the second sub-packaging phototube 42, and the discharge phototube 43 is greater than the threshold time, in order to reduce system power consumption.

[0059] This invention also provides a control method for a high-efficiency conveying system, see reference. Figure 1 The high-efficiency conveying system includes a control module 1, a feeding belt 2, a discharging belt 4, and n conveyor belts 3. The control module 1 is electrically connected to the feeding belt 2, the discharging belt 4, and each conveyor belt 3. The n conveyor belts 3 are arranged sequentially between the feeding belt 2 and the discharging belt 4 along the material transport direction. The material is transported from the feeding belt 2 to the conveyor belts 3. In the material transport direction, a front photoelectric tube 31 and a rear photoelectric tube 32 are respectively installed at both ends of each conveyor belt 3. A feeding photoelectric tube 21 is installed at the end of the feeding belt 2 closest to the first conveyor belt. The control module 1 is electrically connected to each front photoelectric tube 31, each rear photoelectric tube 32, and the feeding photoelectric tube 21.

[0061] S10: Obtain the status of each front-end phototube, each rear-end phototube, and the feeding phototube.

[0062] S20: When the feed phototube is in the first state and the rear phototube of the first conveyor belt is in the second state, control the feed belt to transport the material to the first conveyor belt.

[0063] S30: When the state of the front-end photodiode of the m-th conveyor belt is in the first state and the state of the rear-end photodiode of the (m+1)-th conveyor belt is in the second state, control the operation of the m-th conveyor belt.

[0064] S40: When the phototube at the rear end of the nth conveyor belt is in the first state, control all conveyor belts to stop running.

[0065] The phototube's state includes a first state and a second state. The first state is when the phototube detects material, and the second state is when the phototube does not detect material. <n,n≥2。

[0066] The control method of the high-efficiency conveying system has the same beneficial effects as the high-efficiency conveying system, and will not be described in detail here.

[0067] Figure 4 A flowchart of another control method for a high-efficiency conveying system provided in an embodiment of the present invention is shown below. Figure 2 and Figure 4 Optionally, in the material transport direction, a first sub-packaging phototube 41 and a second sub-packaging phototube 42 are sequentially arranged on the discharge belt 4. The first sub-packaging phototube 41 is located at the end of the discharge belt 4 closest to the nth conveyor belt. The distance between the first sub-packaging phototube 41 and the second sub-packaging phototube 42 is equal to the length of the material. The control module 1 is electrically connected to the first sub-packaging phototube 41 and the second sub-packaging phototube 42 respectively.
