Description

Technical Field

[0001] The present invention relates to the technical field of conveying, and particularly to an article conveying system. Background Art

[0002] Whether in coal mines or coal-fired power plants, it is necessary to regularly collect coal samples to ensure that their quality and characteristics meet the standards. Coal sample bottles are used to store these collected samples and transport them to different processing and testing sites through a conveying system.

[0003] Currently, the conveying system usually adopts a pneumatic conveying system. The pneumatic conveying system is connected to relevant nodes such as a fully automatic sample preparation system, an artificial sample preparation room, an automatic sample storage and inspection system, and a laboratory through a transmission pipeline. During the actual working process, by using the suction and blowing of a power blower, a positive and negative air pressure difference is formed in the pipeline, so as to realize multi-point mutual transmission of coal sample bottles between various sites.

[0004] Since the diameter of the transmission pipeline can only accommodate one coal bottle, the transmission in the transmission pipeline is unidirectional at the same time, resulting in a low transmission efficiency of the current article conveying system. However, if bidirectional transmission is realized, two transmission pipelines need to be arranged side by side, occupying more space and reducing the space utilization rate of the factory building. Summary of the Invention

[0005] In view of this, the present invention provides an article conveying system to solve the problem of low transmission efficiency of the article conveying system.

[0006] In a first aspect, the present invention provides an article conveying system, which includes:

[0007] At least one conveying line, and each conveying line is provided with a plurality of mutually parallel tracks;

[0008] A receiving box, which is provided with a power device and traveling wheels adapted to move on the tracks, and the power device is connected to the traveling wheels; articles to be conveyed are suitable to be stored in the receiving box;

[0009] Each track has a first state of conveying the receiving box in a first direction and a second state of conveying the receiving box in a second direction; the first direction is opposite to the second direction.

[0010] Beneficial effects: In this embodiment, a conveyor line is provided, and a plurality of mutually parallel tracks are arranged on the conveyor line. During use, technicians can set the specific running direction of each track according to the actual situation, that is, each track can be switched independently, so it is possible to avoid congestion caused by path conflicts in a single-track system. Therefore, compared with the current one-way transmission of a single pipeline, the two-way transportation achieved by this technical solution through a single conveyor line can significantly improve the transmission efficiency. Moreover, there is no need to additionally set up other conveyor lines, which can occupy less space and further improve the space utilization rate of the factory building.

[0011] In an alternative embodiment, the conveyor line is a conveyor rack in an "I" shape, and semi-enclosed installation spaces are formed on both sides of the conveyor rack, and at least one track is suitable for being installed in the installation space.

[0012] Beneficial effects: In this embodiment, the "I" shape structure has high bending and compressive resistance, can bear heavy loads, such as a containment box filled with coal samples, and is not easily deformed. Moreover, the semi-enclosed installation space provides rigid support for the track, reducing the vibration of the containment box during operation and the risk of track deviation. At the same time, embedding the track in the installation space can avoid the erosion of the track by external dust, water vapor or mechanical collision. Further, the semi-enclosed structures on both sides form natural guide grooves, restricting the lateral displacement of the walking wheels of the containment box and reducing the probability of derailment. Further, the installation spaces on both sides can achieve "double tracks on one beam". Compared with the current one-way transmission of a single pipeline, the transport capacity of this embodiment is doubled under the same occupied width.

[0013] In an alternative embodiment, the track is a suspended track, and a sliding contact wire is embedded inside the track, and the power equipment obtains power from the track through the sliding contact wire.

[0014] Beneficial effects: In this embodiment, the sliding contact wire is arranged along the entire length of the track, or the sliding contact wire can be set in multiple sections along the entire length of the track, and each sliding contact wire is in a parallel connection, so that each sliding contact wire can work independently without being affected by other sliding contact wires. Moreover, the power equipment of the containment box can obtain power in real time, without relying on batteries or stopping for charging, and there is no need to set up conducting wires, simplifying the overall conductive structure, and thus being more suitable for continuous operation. And power can be directly taken, thereby reducing the energy transmission link of a long line, reducing transmission loss, and ensuring the stable operation of the power equipment.

[0015] In an alternative embodiment, a power-taking module is integrated on the power equipment, and the power-taking module is provided with a plurality of sliding contact pieces, and all the sliding contact pieces are in contact with the sliding contact wire.

[0016] Beneficial effects: In this embodiment, redundant design compatibility is carried out. Therefore, after configuring multiple sliding contacts, multiple contacts can be in contact with the sliding contact wire simultaneously. When a single contact has poor contact, the remaining sliding contacts can still maintain the current path, avoiding the interruption of conveying caused by sudden power failure. Further, the sliding contacts can be arranged in a staggered manner or a rotationally symmetric layout to disperse the wear area and extend the overall module life.

[0017] In an alternative embodiment, the article conveying system further includes:

[0018] A pressure regulating device, disposed on the power taking module; an operating end of the pressure regulating device is connected to the sliding contact; the pressure regulating device is used to adjust the contact pressure between the sliding contact and the sliding contact wire.

[0019] Beneficial effects: In this embodiment, the operating end of the pressure regulating device is connected to each sliding contact. During actual operation, technicians can adjust the pressure according to the actual situation of the track to ensure a tight fit of the contact surface. Compared with the method of using springs in the prior art, it is significantly possible to more finely adjust the pressure applied to each sliding contact, improving the overall fineness of the system.

[0020] In an alternative embodiment, the article conveying system further includes:

[0021] A pressure detection device, disposed between the sliding contact and the sliding contact wire; the pressure detection device is used to detect the contact pressure between the sliding contact and the sliding contact wire; and the pressure detection device is communicatively connected to the pressure regulating device.

[0022] Beneficial effects: In this embodiment, the pressure detection device can detect the contact pressure between the sliding contact and the sliding contact wire in real time, and then feedback the contact pressure to the pressure regulating device. The pressure regulating device can thus adaptively adjust the pressure according to the undulation of the track surface during operation or the wear of the sliding contact, and further ensure a tight fit of the contact surface between the sliding contact and the sliding contact wire.

[0023] In an alternative embodiment, the power equipment includes:

[0024] A power controller, disposed on the accommodation box;

[0025] A driving wheel, a transmission side of the driving wheel is connected to the power controller, and a driving side of the driving wheel is connected to the walking wheel.

[0026] In an alternative embodiment, a control system is further disposed on the accommodation box, and the control system is communicatively connected to the power equipment.

[0027] In an alternative embodiment, the conveying line further includes:

[0028] A stopper, which is arranged on the track; the stopper is communicatively connected to the control system; when the accommodation box reaches a predetermined area, the control system sends a signal to the stopper to activate the stopper, and the accommodation box stops moving after reaching the position of the stopper.

[0029] Beneficial effects: In practical applications, the stopper uses a composite positioning of a Hall sensor and a mechanical stop block, so as to ensure the moving accuracy of the accommodation box, avoid overtravel or deviation of the accommodation box, improve the positioning accuracy, reduce the collision risk, and significantly reduce the failure rate. At the same time, the stopper can also be used to gradually decelerate the accommodation box. For example, when it is 5 m away from the stopper, the first-stage deceleration is triggered, and when it is 1 m away from the stopper, the second-stage deceleration is triggered, thereby avoiding the material spill caused by sudden stop.

[0030] In an optional implementation manner, the article conveying system is provided with a central control system, and a power-on switch is separately arranged on each section of the sliding contact line; the central control system is communicatively connected to the stopper and the power-on switch at the same time;

[0031] When the accommodation box reaches the predetermined area, the central control system controls the power-on switches on all the sliding contact lines in the predetermined area to be turned off;

[0032] When the accommodation box leaves the predetermined area, the central control system controls the power-on switches on all the sliding contact lines in the predetermined area to be turned on.

[0033] Beneficial effects: The stopper is installed at a key position on the track and is used to detect whether the coal bottle transporter reaches a preset safety boundary or a specific area. When the transporter approaches or crosses the set limit point, the stopper will immediately trigger a signal to notify the central control system to take corresponding measures. When the stopper is triggered, the central control system will immediately send an instruction to cut off the power supply of the sliding contact line in the high-risk area. This can prevent the transporter from entering the dangerous area and avoid potential safety accidents. Only after confirming safety, such as when the transporter has left the high-risk area, will the central control system reconnect the power supply to resume normal power supply.

[0034] In an optional implementation manner, the conveyor line further includes:

[0035] An information acquisition device, which is arranged at the starting end of the conveyor line; the information acquisition device is communicatively connected to the control system; the information acquisition device is used to acquire information about the articles in the accommodation box.

[0036] In an optional implementation manner, the accommodation box is provided with a chip, and the information corresponding to the articles in the accommodation box is stored in the chip; the chip is communicatively connected to the information acquisition device.

[0037] Beneficial effects: In this embodiment, by setting a chip which stores information about the items in the storage box, an information acquisition device, such as a card reader, is used to read the information and transmit it to the central control system of the item conveying system. After receiving the signal, the central control system sends an instruction to the power device of the storage box, and the storage box can be sent to the corresponding receiving and sending station, thereby further determining the specific destination of the storage box.

[0038] In an alternative embodiment, when the storage box drives the chip to move close to the information acquisition device so that the distance between the chip and the information acquisition device is within a preset distance, the information acquisition device automatically reads the information of the items in the chip.

[0039] In an alternative embodiment, the item conveying system has a first operating state of automatic operation and a second operating state of manual operation; when the item conveying system is operating normally, it is in the first operating state; when the item conveying system fails, it switches from the first operating state to the second operating state.

[0049] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0050] Whether in coal mines or coal-fired power plants, it is necessary to regularly collect coal samples to ensure that their quality and characteristics meet the standards. Coal sample bottles are used to store these collected samples and transport them to different processing and testing sites through a conveying system.

[0051] Currently, the conveying system usually adopts a pneumatic conveying system. The pneumatic conveying system is connected to relevant nodes such as a fully automatic sample preparation system, an artificial sample preparation room, an automatic sample storage and inspection system, and a testing laboratory through transmission pipelines. During the actual working process, by using the suction and blowing of a power fan, a positive and negative air pressure difference is formed in the pipeline, so as to realize multi-point mutual transmission of coal sample bottles between various sites.

[0052] Since the diameter of the transmission pipeline can only accommodate one coal bottle, the transmission in the transmission pipeline is unidirectional at the same time, resulting in a low transmission efficiency of the current article conveying system. However, if bidirectional transmission is achieved, two transmission pipelines need to be arranged side by side, occupying more space and reducing the space utilization rate of the workshop.

[0053] In view of this, the present invention provides an article conveying system to solve the problem of low transmission efficiency of the article conveying system.

[0054] The following combines Figures 1 to 3 , and describes the embodiments of the present invention.

[0055] According to an embodiment of the present invention, on the one hand, an article conveying system is provided, and the article conveying system includes a conveying line 1 and a storage box 2.

[0056] Specifically, in this embodiment, at least one conveying line 1 is provided, and each conveying line 1 is provided with a plurality of parallel tracks. That is to say, each conveying line 1 can perform multiple conveying routes at the same time. For example, the tracks can be adjusted to convey in the same direction, or one or several of them can be selected to convey in the other direction.

[0057] Furthermore, in this embodiment, the storage box 2 is provided with a power device and traveling wheels 4 adapted to move on the tracks, the power device is connected to the traveling wheels 4, and the storage box 2 is adapted to store articles to be conveyed.

[0058] Each track has a first state of conveying the storage box 2 in a first direction and a second state of conveying the storage box 2 in a second direction; the first direction is opposite to the second direction. In this embodiment, the storage box 2 can be a coal sample bottle box, and the article to be conveyed is a coal sample bottle. In this way, the coal sample bottle box can operate in a bidirectional manner at the same time.

[0059] With such a setting, in this embodiment, the conveying line 1 is provided, and a plurality of parallel tracks are provided on the conveying line 1. During use, technicians can set the specific running direction of each track according to the actual situation, that is, each track can be individually switched in direction, so that congestion caused by path conflicts in a single-track system can be avoided. Therefore, compared with the current unidirectional transmission of a single pipeline, the technical solution of realizing bidirectional transportation through a single conveying line 1 can significantly improve the transmission efficiency. Moreover, there is no need to additionally set other conveying routes, so that less space can be occupied, and further the space utilization rate of the workshop can be improved.

[0060] Further, in an alternative embodiment, the conveyor line 1 is a conveyor frame in an "I" shape, that is, an "I"-shaped track is adopted. Semi-enclosed installation spaces are formed on both sides of the conveyor frame, and at least one track is suitable for being installed in the installation space.

[0061] With such a setting, in this embodiment, the "I" shape structure has high bending and compressive resistance performance and can bear heavy loads, such as the accommodation box 2 filled with coal samples, without being easily deformed. Moreover, the semi-enclosed installation space provides rigid support for the track, reducing the vibration of the accommodation box 2 during operation and the risk of track deviation. At the same time, embedding the track into the installation space can prevent the track from being eroded by external dust, water vapor or mechanical collision. Further, the semi-enclosed structures on both sides form natural guide grooves, restricting the lateral displacement of the traveling wheels 4 of the accommodation box 2 and reducing the probability of derailment. Further, the installation spaces on both sides can achieve "one beam with two tracks". Compared with the current single-pipeline one-way transmission, the transportation capacity of this embodiment is doubled under the same occupied width.

[0062] Further, in an alternative embodiment, the track is a hanging track, and a sliding contact wire is embedded inside the track. The power equipment obtains electricity from the track through the sliding contact wire. During the operation of the system, power is obtained by the power-taking method of the sliding contact wire and is regulated by the hanging track coal bottle conveying control system, and the coal sample is conveyed to a designated place. This application applies the hanging track coal bottle conveying system to the intelligent sampling, preparation and analysis system and is regulated by the hanging track coal bottle conveying control system to realize automatic and intelligent coal bottle conveying.

[0063] With such a setting, in this embodiment, the sliding contact wire is arranged along the entire length of the track, or the sliding contact wire can be set in multiple segments along the entire length of the track. Each sliding contact wire is in a parallel connection, so that each sliding contact wire can work independently without being affected by other sliding contact wires. Moreover, the power equipment of the accommodation box 2 can obtain electricity in real time, without relying on a battery or stopping for charging, and there is no need to set up a conducting wire, simplifying the overall conductive structure, and thus being more suitable for continuous operation. And power can be directly taken, thereby reducing the energy transmission link of a long line, reducing transmission loss and ensuring the stable operation of the power equipment. Further, the power-taking method of the sliding contact wire provides power for the conveying system, providing continuous and stable power supply to ensure the efficient operation of the conveying system. The sliding contact wire has a simple structure and is convenient to maintain, reducing the downtime and maintenance cost of the system. This method has the advantages of high efficiency, stability and convenient maintenance. Its advantages in improving the system operation efficiency and reducing the maintenance cost. Compared with the currently widely used pneumatic transmission system and traditional rack drive, the energy consumption of the sliding contact wire power-taking can save 20% and the failure rate is significantly reduced.

[0064] Further, in an alternative embodiment, a power taking module is integrated on the power device, and the power taking module is provided with a plurality of sliding contacts, and all the plurality of sliding contacts are in contact with the sliding contact wire.

[0065] With such a setting, redundant design compatibility is carried out in this embodiment. Therefore, after configuring a plurality of sliding contacts, a plurality of contacts can be in contact with the sliding contact wire simultaneously. When a single contact is poorly contacted, the remaining sliding contacts can still maintain the current path, avoiding the interruption of conveying caused by sudden power failure. The power supply continuity is increased to 99.9%, supporting the stable operation of high-power devices. Further, the sliding contacts can be arranged in a staggered manner or a rotationally symmetric layout to disperse the wear area and extend the overall module life.

[0066] Further, in an alternative embodiment, the article conveying system further includes a pressure regulating device, and the pressure regulating device is arranged on the power taking module; an operating end of the pressure regulating device is connected to the sliding contact; the pressure regulating device is used to regulate the contact pressure between the sliding contact and the sliding contact wire.

[0067] With such a setting, in this embodiment, the operating end of the pressure regulating device is connected to each sliding contact. During actual operation, technicians can adjust the pressure according to the actual situation of the track to ensure that the contact surface fits closely. Compared with the method of using a spring in the prior art, it is obviously possible to more finely adjust the pressure applied to each sliding contact, improving the overall fineness of the system.

[0068] Further, in an alternative embodiment, the article conveying system further includes a pressure detecting device, and the pressure detecting device is arranged between the sliding contact and the sliding contact wire; the pressure detecting device is used to detect the contact pressure between the sliding contact and the sliding contact wire; and the pressure detecting device is communicatively connected to the pressure regulating device.

[0069] With such a setting, in this embodiment, the pressure detecting device can detect the contact pressure between the sliding contact and the sliding contact wire in real time, and then feedback the contact pressure to the pressure regulating device. The pressure regulating device can thus adaptively adjust the pressure according to the undulation of the track surface during operation or the wear of the sliding contact, and further ensure that the contact surface between the sliding contact and the sliding contact wire fits closely.

[0070] Further, in an alternative embodiment, the power device includes a power controller 6 and a driving wheel 3.

[0071] Specifically, in this embodiment, the power controller 6 is arranged on the accommodation box 2. The driving side of the driving wheel 3 is connected to the power controller 6, and the driven side of the driving wheel 3 is connected to the traveling wheel 4. The power controller 6 drives the driving wheel 3 to rotate, and the driving wheel 3 drives the traveling wheel 4 to rotate, thereby driving the coal sample bottle box to move on the "I"-shaped track.

[0072] Further, in an alternative embodiment, a control system is also arranged on the accommodation box 2, and the control system is communicatively connected to the power equipment. The control system is used to control the start and stop of the power equipment.

[0073] Further, in an alternative embodiment, the conveyor line 1 further includes a stopper 5. The stopper 5 is arranged on the track, and the stopper 5 is communicatively connected to the control system. When the accommodation box 2 reaches a predetermined area, the control system sends a signal to the stopper 5 to activate the stopper 5. After the accommodation box 2 reaches the position of the stopper 5, it stops moving. In this embodiment, the stopper 5 adopts a photoelectric switch or an encoder, which is linked with the control system, and can detect the position of the coal bottle in real time and dynamically adjust the conveying path.

[0074] That is to say, when the coal sample bottle box is about to reach the predetermined position, the control system sends a signal to the stopper 5, the stopper 5 is activated, and the coal sample bottle stops naturally after reaching the position of the stopper 5. The entire transmission process is automatically completed without human intervention.

[0075] With such a setting, in practical applications, the stopper 5 adopts the composite positioning of a Hall sensor and a mechanical stop block, so as to ensure the moving accuracy of the accommodation box 2, avoid overtravel or deviation of the accommodation box 2, improve the positioning accuracy, reduce the collision risk, and significantly reduce the failure rate. At the same time, multi-stage stoppers 5 are arranged at key nodes of the track, and segmented control is realized through PLC programming, so that the stopper 5 can be used to gradually decelerate the accommodation box 2. For example, when it is 5 m away from the stopper 5, the first-stage deceleration is triggered, and when it is 1 m away from the stopper, the second-stage deceleration is carried out, thereby avoiding the material spill caused by sudden stop.

[0076] Further, in an alternative embodiment, the article conveying system is provided with a central control system, and a power-on switch is separately arranged on each section of the sliding contact wire. The central control system is communicatively connected to the stopper 5 and the power-on switch at the same time.

[0077] Specifically, when the accommodation box 2 reaches the predetermined area, the central control system controls the power-on switches on all the sliding contact wires in the predetermined area to be turned off; when the accommodation box 2 leaves the predetermined area, the central control system controls the power-on switches on all the sliding contact wires in the predetermined area to be turned on. In this embodiment, a linkage design is carried out for the power taking of the stopper 5 and the sliding contact wire to deepen the intelligent control logic.

[0078] Set in this way, the stopper 5 is installed at the key position of the track to detect whether the coal bottle transporter reaches the preset safety boundary or specific area. When the transporter approaches or crosses the set limit point, the stopper 5 will immediately trigger a signal to notify the central control system to take corresponding measures. When the stopper 5 is triggered, the central control system will immediately send an instruction to cut off the power supply of the trolley wire in the high-risk area. This can prevent the transporter from entering the dangerous area and avoid potential safety accidents. Only after confirming safety, such as the transporter has left the high-risk area, will the central control system reconnect the power supply to restore normal power supply.

[0079] Furthermore, in an alternative embodiment, the conveyor line 1 further includes an information acquisition device. The information acquisition device is arranged at the starting end of the conveyor line 1 and is communicatively connected to the control system; the information acquisition device is used to acquire information about the items in the storage box 2. The information acquisition device can be manually input by technicians, or a two-dimensional code can be set on the storage box 2. The two-dimensional code is bound to the information of the items. The information acquisition device is a code scanning device. After scanning the two-dimensional code on the storage box 2, it automatically acquires the information about the items in the storage box 2.

[0080] Furthermore, in an alternative embodiment, the storage box 2 is provided with a chip. The chip stores information corresponding to the items in the storage box 2, and the chip is communicatively connected to the information acquisition device.

[0081] Set in this way, in this embodiment, by setting a chip which stores information corresponding to the items in the storage box 2, using an information acquisition device, such as a card reader, to read the information and transmit it to the central control system of the item conveying system. After receiving the signal, the central control system sends an instruction to the power equipment of the storage box 2, and the storage box 2 can be sent to the corresponding receiving and dispatching station, and further determines the specific destination of the storage box 2.

[0082] Furthermore, in an alternative embodiment, when the storage box 2 drives the chip to move close to the information acquisition device so that the distance between the chip and the information acquisition device is within a preset distance, the information acquisition device automatically reads the information of the items in the chip.

[0083] Furthermore, in an alternative embodiment, the item conveying system has a first operating state of automatic operation and a second operating state of manual operation; when the item conveying system is operating normally, it is in the first operating state; when the item conveying system fails, it switches from the first operating state to the second operating state.

[0084] Specifically, the article conveying system can standby for 24 hours to wait for conveying coal sample bottles. At the same time, the article conveying system has automatic and manual operation functions, is associated with the central control system, and has a good man-machine dialogue interface. The operating status and working parameters of the equipment can be transmitted to the display screen through the central control system for real-time display. Moreover, the central control system has a fault alarm and information prompt function to judge the cause of the fault. When a fault occurs in the article conveying system, it can be switched to the manual mode.

[0085] Moreover, in this embodiment, the central control system can monitor and adjust the conveying process in real time to ensure the stable operation and efficient management of the system. The central control system can also be specifically linked with the coal quality control system of the coal yard in real time. The central control system can collect and analyze the conveying data in real time for intelligent management and optimization. The conveying path of the coal bottles is dynamically optimized according to the overall technological process.

[0086] During the operation process, the full-process automation rate is increased to 95%, the manual intervention is reduced by 80%, and the overall operation cycle is shortened by 40%.

[0087] This technical solution solves the pain points existing in the existing rail conveying system, such as high failure rate, low operation efficiency, low positioning accuracy, and insufficient intelligence, through three core technologies: dynamic control by the limiter 5, highly reliable power supply by the double-rail sliding contact line, and deep integration of the intelligent sampling, preparation, and analysis system.

[0088] Furthermore, as Figure 2 shown, this article conveying system can be called a hanging-rail coal bottle conveying system, which is used to connect each station, for example, a fully automatic sample preparation system, an online total moisture system, an artificial laboratory station, a fully automatic storage and sample checking cabinet, a fully automatic testing system, and a waste sample station. These stations are all the stations that the coal sample bottles need to pass through during the conveying process. This embodiment is only for illustration.

[0089] Furthermore, as Figure 3 shown, this article conveying system can be called a hanging-rail coal bottle conveying system, Figure 3 which shows the specific working process of this embodiment.
