Description

Technical Field

[0001] This utility model relates to the field of material transportation technology, and in particular to a vehicle dispatching and cabinet finding confirmation device. Background Technology

[0002] A distribution crane is a conveying device that distributes materials on a production line to different storage containers. Because there are many storage containers on the production line, the accuracy of positioning is crucial during the container searching and reciprocating material handling processes of the distribution crane.

[0003] The storage cabinets on the yarn-making line are arranged in parallel, with multiple sets of cabinets sharing a single distribution crane. During feeding, the distribution crane transports the material to the fabrication crane above the target cabinet. The fabrication crane's reciprocating motion spreads the material evenly into the cabinet. Before production begins, a work order is issued from the central control unit. After receiving the work order in the production control system, the system selects the cabinet number and starts the equipment for no-load operation. The distribution crane searches for the cabinet according to the set cabinet number. When the proximity sensor on the distribution crane track above the target cabinet is blocked, the cabinet search is complete, and the central control unit can execute the work order to officially start the material feeding process. In actual production, relying solely on photoelectric sensors to determine the location of the distribution crane is a relatively simple technical method. Furthermore, due to electrical and mechanical faults such as photoelectric switch misalignment and abnormal signal transmission, there have been instances where the distribution crane failed to locate the cabinet without alarming. If manual first-pass inspection is inadequate, it often leads to major quality incidents such as batch mixing and brand mixing. Utility Model Content

[0032] Figure 1 This is a structural schematic diagram of a crane dispatcher confirmation device according to an embodiment of the present utility model. Figure 2 This is a circuit connection diagram of a vehicle dispatching cabinet confirmation device according to an embodiment of the present utility model. (Combined with...) Figure 1 and Figure 2 As shown, the distribution crane cabinet finding confirmation device includes: distribution crane 1, distribution crane guide rail 2, distance measuring unit 3, proximity switch 4, baffle 5 and control unit 6;

[0033] The distribution trolley 1 is set on the distribution trolley guide rail 2, and at least two storage cabinets 7 are set on the side of the distribution trolley guide rail 2 away from the distribution trolley 1; the movement control output terminal a of the control unit 6 is communicatively connected to the movement control receiver terminal a' of the distribution trolley 1.

[0034] The ranging unit 3 is installed on the distribution trolley guide rail 2 and the ranging output terminal b of the ranging unit 3 is communicatively connected to the ranging receiver terminal b' of the control unit 6.

[0035] The proximity switch 4 is installed on the distribution trolley rail 2, and at least one proximity switch 4 is installed on the distribution trolley rail 2 corresponding to each storage cabinet 7; the baffle 5 is installed on the distribution trolley 1 and is located on the propagation path of the detection light output by the proximity switch 4; the photoelectric trigger terminal c of the proximity switch 4 is communicatively connected to the photoelectric receiver terminal c' of the control unit 6.

[0036] The distribution trolley 1 is used to transport and distribute materials on the production line to different storage cabinets 7. The distribution trolley 1 is mounted on the distribution trolley guide rail 2 and can move along the distribution trolley guide rail 2. At least two storage cabinets 7 are set on the side of the distribution trolley guide rail 2 away from the distribution trolley 1. The distribution trolley 1 can transport materials to the corresponding storage cabinet 7 by moving along the distribution trolley guide rail 2.

[0037] The control unit 6 has a movement control output terminal a connected to the movement control receiver terminal a' of the distribution trolley 1. The control unit 6 can output movement control signals to the distribution trolley 1 to control the distribution trolley 1 to move along the distribution trolley guide rail 2.

[0038] The ranging unit 3 can detect the distance between one end of the distribution trolley guide rail 2 and the distribution trolley 1. Since the storage cabinet 7 and the distribution trolley guide rail 2 are in fixed positions, and the ranging unit 3 is also fixed in the same position on the distribution trolley guide rail 2, the distribution trolley 1 moves along the distribution trolley guide rail 2, so that the ranging unit 3 can detect the distance between one end of the distribution trolley guide rail 2 and the distribution trolley 1, and thus determine whether the distribution trolley 1 has correctly located the cabinet.

[0039] The proximity switch 4, in conjunction with the baffle 5, utilizes the photoelectric effect to locate and detect storage cabinets. The proximity switch 4 is mounted on the distribution trolley rail 2, and its position is fixed. At least one proximity switch 4 is installed on the distribution trolley rail 2 corresponding to each storage cabinet 7. The baffle 5 is mounted on the distribution trolley 1, and its movement causes the baffle 5 to move. When the distribution trolley 1 moves, the baffle 5 moves into the detection range of the proximity switch 4, thus blocking the detection light and triggering the proximity switch 4 at the corresponding storage cabinet 7 location. The photoelectric trigger terminal c of the proximity switch 4 is communicatively connected to the photoelectric receiver terminal c' of the control unit 6, inputting the trigger signal to the control unit 6.

[0040] The control unit 6 can determine whether the dispatching trolley 1 has reached the cabinet based on the trigger signal of the proximity switch 4 and the measurement distance of the ranging unit 3.

[0041] Specifically, control unit 6 receives the work order and identifies the target storage cabinet 7 as storage cabinet 7 number 1. Control unit 6 outputs a movement control signal to the distribution trolley 1, which moves along the distribution trolley guide rail 2. At this time, the ranging unit 3 detects the distance between the distribution trolley 1 and one end of the distribution trolley guide rail 2 in real time. Control unit 6 determines in real time whether the real-time distance meets the preset distance corresponding to storage cabinet 7 number 1. The proximity switch 4 corresponding to storage cabinet 7 detects in real time whether there is a baffle 5 blocking the detection light, and outputs a trigger signal to control unit 6 when the light is blocked. When the real-time distance is equal to the preset distance and the trigger signal is received, it indicates that the distribution trolley 1 has reached the storage cabinet.

[0042] It is understood that the technical solution of this utility model embodiment simultaneously sets up a baffle 5, a proximity switch 4 and a ranging unit 3 on the cabinet locating confirmation device. The cabinet locating detection is performed simultaneously through the ranging principle and the photoelectric effect principle, and dual detection is performed to avoid the problem of missed alarms and false alarms caused by the failure of the photoelectric sensing of the proximity switch 4.

[0043] The technical solution of this utility model embodiment is to set up a distribution trolley 1, a distribution trolley guide rail, a ranging unit, a proximity switch, a baffle and a control unit in the distribution trolley cabinet locating confirmation device. Through the communication connection between the control unit and the distribution trolley, the ranging unit and the proximity switch, dual cabinet locating detection of the ranging unit and the proximity switch is realized. This avoids the problem of missed alarms and false alarms caused by the failure of the photoelectric sensing of the proximity switch, and prevents major abnormal accidents caused by cabinet locating errors.

[0044] Optional, continue to refer to Figure 1 As shown, the ranging unit 3 includes a rangefinder 31 and a reflector 32;

[0045] The rangefinder 31 is installed at one end of the distribution trolley guide rail 2 and emits laser light along the first direction x; the reflector 32 is installed at one end of the distribution trolley 1 and receives and reflects the laser light.

[0046] The distribution trolley 1 moves along the second direction y on the distribution trolley guide rail 2; wherein the first direction x and the second direction y are perpendicular.

[0047] The rangefinder 31 can be a device that measures distance based on the principle of light reflection. In some embodiments, the rangefinder 31 is a laser rangefinder 31 that emits laser light during the detection process. The rangefinder 31 is mounted on one end of the distribution trolley guide rail 2. The rangefinder 31 emits laser light along a first direction x, and the distribution trolley 1 moves along the distribution trolley guide rail 2 along a second direction y. The reflector 32 reflects the laser light and is mounted on one end of the distribution trolley 1, moving with the distribution trolley 1. Since the parameters of the reflected light are different at different distances, the rangefinder 31 can measure the distance between the reflector 32 and the rangefinder 31 based on the reflection of the light, thereby obtaining the real-time distance between the distribution trolley 1 and one end of the distribution trolley guide rail 2.

[0048] It is understandable that the ranging unit 3 includes a rangefinder 31 and a reflector 32. The rangefinder 31 is set at one end of the distribution trolley guide rail 2, and the reflector 32 is set on the distribution trolley 1. This allows the laser light emitted by the rangefinder 31 to be reflected by the reflector 32, thereby enabling the rangefinder 31 to obtain different distance signals according to the movement of the distribution trolley 1, ensuring the accuracy and reliability of the real-time distance acquisition by the ranging unit 3.

[0049] The technical solution of this utility model embodiment is to set a rangefinder and a reflector in the ranging unit. The rangefinder is set at one end of the distribution trolley guide rail, and the reflector is set on the distribution trolley. This allows the laser light emitted by the rangefinder to be reflected by the reflector, so that the rangefinder can obtain different distance signals according to the movement of the distribution trolley, thus ensuring the accuracy and reliability of the rangefinder unit in obtaining real-time distance.

[0050] Optional, continue to refer to Figure 1 As shown, the ranging unit 3 also includes a support 33;

[0051] The bracket 33 is fixedly connected to one end of the distribution trolley guide rail 2; the rangefinder 31 is fixedly mounted on the bracket 33.

[0052] The bracket 33 serves to fix the rangefinder 31 to the distribution guide rail 2.

[0053] In some embodiments, the bracket 33 may be an "L" shaped bracket 33, with one end fixedly connected to the distribution trolley guide rail 2 and the other end fixedly connected to the rangefinder 31, so that the rangefinder 31 can emit laser light along the first direction x, outside the operating range of the distribution trolley 1, to avoid collision or squeezing of the device due to the distribution trolley 1 running beyond its limit.

[0054] The technical solution of this utility model embodiment fixes the rangefinder 31 on the distribution trolley guide rail 2 by the bracket 33, ensuring the stability of the rangefinder 31 and enabling the rangefinder 31 to emit laser light along the first direction x, thus ensuring the accuracy and reliability of the detection data.

[0055] Optional, continue to refer to Figure 1 As shown, the ranging unit 3 also includes a rotating shaft 34 and a dust cover 35;

[0056] The dust cover 35 is rotatably connected to the bracket 33 via the rotating shaft 34; the bracket 33 and the dust cover 35 form a receiving space, and the rangefinder 31 is set in the receiving space.

[0057] The dust cover 35 can be opened or closed by rotating the rotating shaft 34. The dust cover 35 is rotatably connected to the bracket 33 via the rotating shaft 34. When the dust cover 35 is closed, the bracket 33 and the dust cover 35 form a closed receiving space, in which the rangefinder 31 is placed to prevent dust generated during material unloading by the distribution crane 1 from contaminating the lens and affecting the detection accuracy. When the distribution crane 1 is searching for the cabinet, the dust cover 35 is opened via the rotating shaft 34, and the rangefinder 31 emits laser light along the first direction x.

[0058] The technical solution of this utility model embodiment is to set a rotating shaft and a dust cover in the ranging unit. The dust cover can be opened or closed according to the rotation of the rotating shaft, and the dust cover is closed when the trolley is discharging material, so as to avoid the dust generated when the trolley is discharging material from contaminating the lens and affecting the detection accuracy.

[0059] Optional, continue to refer to Figure 1 and Figure 2 As shown, the rotation control terminal d of the control unit 6 is communicatively connected to the rotation receiving terminal d' of the rotation shaft 34.

[0060] The control unit 6 can output a positive rotation signal to the rotating shaft 34 through the rotation control terminal d, thereby controlling the clockwise rotation of the rotating shaft 34 to open the dust cover 35.

[0061] For example, when the control unit 6 controls the movement of the vehicle 1, it outputs a positive rotation signal to the rotating shaft 34, opens the dust cover 35, and causes the rangefinder 31 to output laser light for distance detection.

[0062] Optional, continue to refer to Figure 1 and Figure 2 As shown, the cabinet search end e of the control unit 6 is communicatively connected to the rotation stop end e' of the rotating shaft 34.

[0063] Among them, the cabinet search end e of the control unit 6 can output a reverse rotation signal to the rotating shaft 34 to control the counterclockwise rotation of the rotating shaft 34, thereby closing the dust cover 35.

[0064] For example, after the distribution crane 1 finishes searching for the cabinet, the material feeding begins. At this time, the control unit 6 can detect the flow rate of the electronic scale at the front end of the production line to determine whether the cabinet searching has ended. After the distribution crane 1 finishes searching for the cabinet, the cabinet searching end e outputs a reverse motion signal to control the dust cover 35 to close, so as to prevent the dust generated when the distribution crane 1 unloads the material from contaminating the lens and affecting the detection accuracy, thereby protecting the ranging unit 3.

[0065] The technical solution of this utility model embodiment controls the rotation of the rotating shaft through the rotation control end of the control unit, thereby opening the dust cover. The rotating shaft is then controlled to close the dust cover through the cabinet search end of the control unit, thus achieving the purpose of timely opening and closing of the dust cover and ensuring the reliability and accuracy of the ranging unit.

[0066] Optional, continue to refer to Figure 2 As shown, it also includes a display unit 8;

[0067] The ranging information output terminal f of the control unit 6 is communicatively connected to the ranging information receiving terminal f' of the display unit 8.

[0068] The display unit 8 can be used to output display information.

[0069] Specifically, the distance measurement information output terminal f of the control unit 6 is communicatively connected to the distance measurement information receiving terminal f' of the display unit 8. The control unit 6 can output real-time distance measurement information to the display unit 8, and the display unit 8 can display the measured distance in real time, thereby enabling staff to obtain the measurement results in real time and perform real-time monitoring.

[0070] The technical solution of this utility model embodiment, by setting up a display unit, connects the distance measurement information output terminal of the control unit with the distance measurement information receiving terminal of the display unit, so that the control unit can output the measured distance of the distance measuring instrument in real time and input the measured distance to the display unit for real-time display, ensuring that the staff can obtain the working status of the display unit in a timely manner, so as to monitor the dispatching of vehicles in real time.

[0071] Optional, continue to refer to Figure 1 and Figure 2 As shown, the control unit 6 also includes a cabinet search confirmation output terminal g;

[0072] The cabinet locating confirmation output terminal g is connected to the hoist 9 for communication; the cabinet locating confirmation output terminal g is used to output a correct cabinet locating signal when the real-time distance input by the ranging unit 3 is equal to the preset distance and the trigger signal of the proximity switch 4 is received.

[0073] The cabinet locating confirmation output terminal g can be used to output a correct cabinet locating signal. When the control unit 6 receives the trigger signal from the proximity switch 4 and determines that the real-time distance is equal to the preset distance, it indicates that both the proximity switch 4 and the rangefinder 31 have detected that the dispatching crane 1 has located the target storage cabinet 7. At this time, the cabinet locating confirmation output terminal g outputs a correct cabinet locating signal to the hoist 9. The hoist 9 controls the hoisting belt to operate and transfer the material to the target storage cabinet 7, completing the cabinet locating and storage process.

[0074] The technical solution of this utility model embodiment connects the cabinet search confirmation output terminal of the control unit to the hoist. After cabinet search confirmation, the hoist is controlled to operate and complete the material transfer, ensuring the accuracy of material storage and preventing quality abnormality accidents.

[0075] Optional, continue to refer to Figure 1 and Figure 2 As shown, the control unit 6 also includes a cabinet search error output terminal h;

[0076] The cabinet search error output terminal h is connected to the hoist 9 for communication; the cabinet search error output terminal h is used to output a cabinet search error signal when the real-time distance input by the ranging unit 3 is not equal to the preset distance and / or the trigger signal of the proximity switch 4 is not received.

[0077] The cabinet search error output terminal h can be used to output a cabinet search error signal. When the control unit 6 does not receive the trigger signal from the proximity switch 4 and determines that the real-time distance is equal to the preset distance, the proximity switch 4 may be malfunctioning. At this time, the cabinet search error signal is output to the hoist 9, controlling the hoist 9 to stop operating and stop material feeding, and maintenance personnel perform equipment inspection.

[0078] When the control unit 6 does not receive the trigger signal from the proximity switch 4 and determines that the real-time distance is not equal to the preset distance, it may be that the distribution crane 1 is in the wrong cabinet search. At this time, the cabinet search error signal is output to the hoist 9, and the hoist 9 is controlled to stop running and stop material feeding. The maintenance personnel then check the distribution crane 1.

[0079] When the control unit 6 receives the trigger signal from the proximity switch 4 and determines that the real-time distance is not equal to the preset distance, it may be that the proximity switch 4 or the rangefinder 31 has malfunctioned. At this time, the control unit 6 outputs a cabinet search error signal to the hoist 9, controls the hoist 9 to stop running, stops material feeding, and maintenance personnel perform equipment inspection.

[0080] It is understandable that the crane 1 will only be judged to be in position when it receives the trigger signal from the proximity switch 4 and the real-time distance is equal to the preset distance. Otherwise, if the cabinet is not found or the detection equipment malfunctions, the elevator 9 needs to be stopped and the equipment needs to be inspected to ensure the reliability and accuracy of material storage.

[0081] The technical solution of this utility model embodiment connects the cabinet-finding error output terminal of the control unit to the hoist. When it is determined that the real-time distance input by the ranging unit is not equal to the preset distance and / or the trigger signal of the proximity switch is not received, the hoist is controlled to stop operating, reminding the staff to perform timely equipment inspection, ensuring the accuracy of material storage, and preventing quality abnormality accidents.

[0082] The specific embodiments described above do not constitute a limitation on the scope of protection of this utility model. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
