Terminal control device and distributed control system for conveying equipment

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This disclosure claims priority to Chinese patent application number 2023233888456, filed with the Chinese Patent Office on December 11, 2023, entitled “A terminal control device and a distributed control system for conveying equipment,” the entire contents of which are incorporated by reference into this disclosure. Technical Field

[0003] The present disclosure relates to the field of logistics technology, and in particular to a terminal control device and a distributed control system for conveying equipment. Background Art

[0004] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art.

[0005] The lightweight material box conveying application solutions currently used in the logistics industry all use a single roller drive card as the drive to realize the conveyance of material box goods. A centralized I / O control solution is adopted, and the control points are integrated in the PLC control cabinet. Each roller control card needs to be individually connected to the PLC control cabinet, and all control points on the conveyor line are introduced to the control cabinet through control cables; and each roller control card also needs to be powered separately. The power supply of each roller control card also needs to be individually connected to the control cabinet, resulting in a large number of cables to be laid, complex on-site construction, and increased maintenance labor costs for the control cabinet.

[0006] In addition, the existing roller control card requires additional photoelectric I / O interface control when driving. Each conveying section of the material box conveying system requires a photoelectric signal to control the stop of the material box. If a centralized solution is used, a separate control line needs to be led out from the main control cabinet, which will also result in a large number of cables to be laid.

[0036] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of the present disclosure. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present disclosure belongs.

[0037] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present disclosure.

[0038] In the absence of conflict, the embodiments of the present disclosure and the features thereof may be combined with each other.

[0039] As shown in Figures 1 to 3, this embodiment provides a terminal control device, including: a first shell 1 and a second shell 3 arranged opposite to each other, the first shell 1 is provided with a first puncture needle 6 and a second puncture needle 7, the first shell 1 and the second shell 3 clamp a power line configured for power supply and a communication line configured for communication; the first puncture needle 6 is configured to puncture the power line to electrically connect to the power line, and the second puncture needle 7 is configured to puncture the communication line to electrically connect to the communication line.

[0040] In this embodiment, one end of the first shell 1 and one end of the second shell 3 are connected via a connecting shaft.

[0041] As an optional embodiment, the first shell 1 and the second shell 3 are of an open-close structure, one side of the first shell 1 and one side of the second shell 3 are movably connected, and the connecting side of the first shell 1 and the second shell 3 is provided with a matching hole-shaft connection structure;

[0042] Optionally, a connecting shaft is provided on the first shell 1 , a connecting hole 10 is provided on the second shell 3 , and the connecting hole 10 is a vertical long hole. The connecting shaft on the first shell 1 is movably provided in the connecting hole 10 of the second shell 3 .

[0043] It should be noted that the first shell 1 and the second shell 3 mainly rely on the tightening of fasteners to puncture the power cord and the communication line. The connection hole 10 is set as a long strip hole to avoid affecting the connection structure. After the first shell 1 and the second shell 3 are merged, when the puncture needle is not inserted, there is a gap between the first shell 1 and the second shell 3. After being connected by fasteners, the puncture needle is vertically inserted into the line.

[0044] It is understandable that as long as the opening and closing connection between the first shell 1 and the second shell 3 can be achieved, the specific connection method is not limited.

[0045] In this embodiment, the first shell 1 and the second shell 3 are fixedly connected by fasteners, so that the first puncture needle 6 pierces the power line after aligning with the power line, and the second puncture needle 7 pierces the communication line after aligning with the communication line.

[0046] As an optional embodiment, both the first shell 1 and the second shell 3 are provided with a through hole 2 configured to pass through a fastener.

[0047] As an optional embodiment, the position where the fastener is fixed, that is, the position of the through hole 2 can be set between the first puncture needle 6 and the second puncture needle 7.

[0048] It is understandable that the position where the fastener is fixed can also be set on one side of the first puncture needle 6 or the second puncture needle 7 or other positions, as long as the fastening connection between the first shell 1 and the second shell 3 and the puncture of the power cord and the communication line can be achieved, without limitation.

[0049] As an optional embodiment, the fastener fixing position can be set at one location, such as in the middle of the surface of the first shell 1, or at two or more locations, such as at both ends of the surface of the first shell 1, which is also not specifically limited.

[0050] As an optional embodiment, the fasteners are bolts, and the fastening connection between the first shell 1 and the second shell 3 is achieved by bolt connection.

[0051] It is understandable that bolt connection is only one embodiment, and other connection methods can also be used, as long as the first shell 1 and the second shell 3 can be securely connected, without limitation.

[0052] As an optional embodiment, the through hole 2 on the first shell 1 passes through the first shell 1 , and the fastener passes through the first shell 1 through the through hole 2 and is fixed to the second shell 3 .

[0053] In this embodiment, the first puncture needle 6 and the second puncture needle 7 pierce the insulation layer of the power cord and the communication line respectively and then contact the wire core, thereby achieving electrical connection; the second shell 3 is provided with a first wire groove 8 configured to pass through the power cord and a second wire groove 9 configured to pass through the communication line, and the first wire groove 8 and the second wire groove 9 respectively correspond to the positions of the first puncture needle 6 and the second puncture needle 7 on the first shell 1, wherein the first puncture needle 6 is aligned with the first wire groove 8 to pierce the power cord and then electrically connect to the power cord; the second puncture needle 7 is aligned with the second wire groove 9 to pierce the communication line and then electrically connect to the communication line.

[0054] The first wire slot 8 and the second wire slot 9 are preferably flat slots. Correspondingly, the power line and the communication line are flat lines corresponding to the first wire slot 8 and the second wire slot 9, respectively, which facilitate positioning and accurate insertion.

[0055] As an optional embodiment, the second shell 3 can also form a positioning mechanism such as a guide column to fix the power cord and the communication line, and then pierce the power cord and the communication line by tightening the fastener with a puncture needle. In this way, the power cord and the communication line can be positioned and punctured by the puncture needle.

[0056] As an optional embodiment, the first puncture needles 6 and the second puncture needles 7 are each provided with two groups, which are configured to form a connection loop after being connected to the corresponding wiring harness; the upper and lower rows of the first puncture needles 6 shown in Figure 1 correspond to the positive and negative lines of the power line respectively, and there is at least one positive puncture needle and one negative puncture needle, and multiple puncture needles can be provided respectively. The provision of multiple puncture needles can reduce the possibility of the puncture needles being unable to connect with the power line or the communication line, thereby ensuring the connection effect. The second puncture needle 7 connected to the communication line is similar.

[0057] In this embodiment, the first housing 1 is further provided with a first slot 4 configured to connect to an actuator motor element, and a second slot 5 configured to connect to a photoelectric detection element.

[0058] It can be understood that the execution motor element can be a motor configured to drive the roller.

[0059] As an optional embodiment, the first slot 4 and the second slot 5 are respectively provided at two ends of the first shell 1 .

[0060] In this embodiment, as shown in Figure 4, the terminal control device mainly processes data through the processor MCU, and the processor is provided with a power interface, an address configuration interface, an optoelectronic IO interface, a debugging interface, a CAN interface, a Hall interface and a PWM interface; the power interface is configured to introduce power from the power circuit to the processor, and the address configuration interface is configured to configure the CAN protocol address; the optoelectronic IO interface is configured to connect to the photoelectric detection element, the debugging interface is configured to debug the processor with an external debugging device, the CAN interface is configured to connect to the communication line, and the Hall interface and PWM are configured to connect to the execution motor.

[0061] Existing control cards require additional photoelectric I / O interfaces for control during drive. Each section of the bin conveying system requires a photoelectric signal to stop the bin. Centralized solutions require cables from the master control cabinet, resulting in a large number of cables. The control device of this embodiment integrates drive and control functions into one, featuring an integrated DI interface. Each section's photoelectric I / O signal input can be connected to the control device nearby, reducing cabling and on-site operation steps.

[0062] As shown in FIG5 , this embodiment provides a distributed control system for conveying equipment, including:

[0063] Multiple terminal control devices as in the above embodiments, each terminal control device is connected to a terminal element;

[0064] The power supply unit and the terminal control device are serially connected to the power supply unit hand in hand through the power supply line;

[0065] The communication unit and the terminal control device are serially connected to the communication unit hand in hand through the communication line.

[0066] In this embodiment, the power supply unit includes an electric control cabinet and a DC power supply device provided in the electric control cabinet, and a plurality of terminal control devices connected in series are connected to the DC power supply device;

[0067] The communication unit includes a PLC master, a switch and a Profinet to CAN gateway, and multiple terminal control devices connected in series are connected to the Profinet to CAN gateway.

[0068] In this embodiment, the terminal element includes an actuator element and a photodetection element.

[0069] In this embodiment, the distributed control system of the conveying equipment includes three parts: a network framework, a power supply framework and a motor framework; among them, the network framework realizes information communication interaction between the on-site PLC and each terminal control device through a switch, and the communication line starts from the first terminal control device and is connected to the remaining terminal control devices in sequence; the power supply framework realizes power supply to each terminal control device, and the power line starts from the first terminal control device and is connected to the remaining terminal control devices in sequence; the motor framework realizes the puncture connection of power supply and communication in the terminal control device and the access of DI signals, etc.; the above three frameworks are combined into a distributed control solution for conveying equipment.

[0070] This embodiment provides a distributed control system for conveying equipment, in which multiple terminal control devices are connected in sequence to avoid having to lead the wiring of all terminal control devices out of the control cabinet, thereby realizing distributed control of the conveying system, reducing on-site control wiring and power supply wiring, and reducing the number of large signal control cabinets.

[0071] Although the above describes the specific implementation methods of the present disclosure in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present disclosure. Those skilled in the art should understand that, based on the technical solution of the present disclosure, various modifications or variations that can be made by those skilled in the art without creative work are still within the scope of protection of the present disclosure. Industrial Applicability

[0072] The above solution can realize distributed control of the conveying system, reduce on-site control wiring and power supply wiring, and reduce the number of large signal control cabinets.
