Description
Technical Field
[0001] This utility model relates to the technical field of narrow strip machine sorting systems, and in particular to a sensor-based installation alarm system and its narrow strip machine sorting system. Background Technology
[0002] Currently, the logistics industry handles a massive volume of parcels, making efficient and accurate parcel sorting crucial. Existing logistics sorting systems often rely on manual sorting, which significantly reduces efficiency, especially for small and medium-sized distribution centers with limited budgets and space. Using larger sorting equipment increases costs. Therefore, finding a solution that is both efficient and space-saving has become a challenge. This is where narrow-belt sorting machines come in. Using narrow-belt sorting equipment in small and medium-sized distribution centers can reduce labor costs and improve sorting efficiency and accuracy.
[0003] Current narrow-band sorting machines have a small footprint, simple structure, easy maintenance, high efficiency, and high accuracy. They can sort various packages of different sizes, making them extremely suitable for small and medium-sized distribution centers. Currently, the common operating speeds of narrow-band machines in the intelligent sorting industry are 1.5m / s, 1.8m / s, 2.0m / s, and 2.5m / s. High-speed moving mechanical parts require comprehensive safety measures to ensure personal safety and equipment safety. It is necessary to strengthen the self-safety protection of narrow-band machines. Therefore, we urgently need a sensor-based alarm system. Utility Model Content
[0004] In response to the shortcomings of the existing production technology, the applicant provides a sensor-based installation alarm system and its narrowband machine sorting system. The system can trigger an alarm by detecting the status of the sensor and can accurately display the alarm location, thereby enabling safe, accurate and efficient fault location.
[0005] The technical solution adopted in this utility model is as follows:
[0006] A sensor-based installation alarm system includes: a first photoelectric sensor, a second photoelectric sensor, a third photoelectric sensor, a fourth photoelectric sensor, a fifth photoelectric sensor, two proximity sensors, two laser rangefinders, a display screen, and an MCU. The first photoelectric sensor is installed at the position of the packing conveyor belt; the second photoelectric sensor is installed at the position of the lower bottom mesh at the front end of the narrow belt; the third photoelectric sensor is installed at the position of the lower bottom mesh at the tail end of the narrow belt; the fourth photoelectric sensor is installed on the transition plate at the tail end of the narrow belt; and the fifth photoelectric sensor is installed at the gap in the transition plate at the tail end of the narrow belt. The two proximity sensors are respectively installed at the front and tail ends of the anti-collision bracket inside the narrow belt. The two laser rangefinders are respectively installed on the left and right sides of the tail end of the narrow belt frame. The first, second, third, fourth, and fifth photoelectric sensors, the proximity sensors, the laser rangefinders, and the display screen are all electrically connected to the MCU.
[0007] Therefore, by detecting the status of the first photoelectric sensor, the second photoelectric sensor, the third photoelectric sensor, the fourth photoelectric sensor, the fifth photoelectric sensor, the proximity sensor, and the laser rangefinder, it is possible to detect whether there is any abnormality at each position of the narrow strip and trigger an alarm, so that the entire narrow strip sorting system can trigger a self-protection mode. The alarm position can be accurately displayed on the display screen, thereby enabling safe, accurate, and efficient fault location.
[0008] Furthermore, the first, second, third, and fourth photoelectric sensors are all through-beam photoelectric sensors; the fifth photoelectric sensor is a reflective photoelectric sensor; and the operating mode of the first, second, third, fourth, and fifth photoelectric sensors is all L mode. Therefore, in well-lit environments, the L mode can more accurately detect changes in light, thus enabling status monitoring of whether the vehicle has detached.
[0009] Furthermore, it also includes: a first mounting bracket, through which the fifth photoelectric sensor is mounted at the gap of the narrow band tail transition plate; the first mounting bracket has a first mounting hole and a second mounting hole, the second mounting hole being an oblong hole. Thus, the reflector is fixed through the first mounting hole, and the position of the reflector is adjusted through the second mounting hole to ensure the fifth photoelectric sensor functions normally.
[0010] Furthermore, it also includes: four second mounting brackets, wherein the first photoelectric sensor is mounted at the position of the packing conveyor via the second mounting brackets, the second photoelectric sensor is mounted at the position of the lower bottom mesh at the front end of the narrow belt via the second mounting brackets, the third photoelectric sensor is mounted at the position of the lower bottom mesh at the tail end of the narrow belt via the second mounting brackets, and the fourth photoelectric sensor is mounted on the transition plate at the tail end of the narrow belt via the second mounting brackets.
[0011] Furthermore, the second mounting bracket has a third mounting hole, a fourth mounting hole, and a fifth mounting hole, both of which are oblong holes. Thus, the positions of the first, second, third, and fourth photoelectric sensors are adjusted through the third mounting hole to ensure their normal operation.
[0012] Furthermore, it also includes: two third mounting brackets, each third mounting bracket having threaded mounting holes for mounting the proximity sensor onto the third mounting bracket; each third mounting bracket is provided with a baffle and a rotating shaft, the rotating shaft passing through the baffle and being fixedly connected to the baffle, both ends of the rotating shaft being rotatably connected to the third mounting bracket. Thus, the distance between the proximity sensor and the baffle can be adjusted via the threaded mounting holes.
[0013] Furthermore, it also includes: two fourth mounting brackets, each fourth mounting bracket having multiple sixth mounting holes for mounting the laser rangefinder sensor onto the fourth mounting bracket; the fourth mounting brackets also have multiple seventh mounting holes, each seventh mounting hole being an oblong shape, for mounting the fourth mounting bracket to the tail end of the narrowband frame. Thus, the illumination position of the laser rangefinder sensor can be adjusted through the seventh mounting holes.
[0014] A narrow-band sorting system includes a sensor-based installation alarm system.
[0015] The beneficial effects of this utility model are as follows:
[0016] This invention uses the status detection of a first photoelectric sensor, a second photoelectric sensor, a third photoelectric sensor, a fourth photoelectric sensor, a fifth photoelectric sensor, a proximity sensor, and a laser rangefinder to detect whether there are any abnormalities at various locations in the narrow strip and trigger an alarm, so that the entire narrow strip sorting system can trigger a self-protection mode. The alarm location can be accurately displayed on the display screen, thereby enabling safe, accurate, and efficient fault location.

[0045] The specific embodiments of this utility model are described below with reference to the accompanying drawings.
[0046] like Figures 1 to 9 The diagram shows the preferred embodiment of this utility model. This embodiment's sensor-based alarm system includes: a first photoelectric sensor 1, a second photoelectric sensor 2, a third photoelectric sensor 3, a fourth photoelectric sensor 4, a fifth photoelectric sensor 5, two proximity sensors 6, two laser rangefinders 7, a display screen 8, and an MCU 9. The first photoelectric sensor 1 is installed at the position of the packing conveyor belt; the second photoelectric sensor 2 is installed at the position of the lower bottom mesh at the front end of the narrow belt; the third photoelectric sensor 3 is installed at the position of the lower bottom mesh at the tail end of the narrow belt; the fourth photoelectric sensor 4 is installed on the transition plate at the tail end of the narrow belt; the fifth photoelectric sensor 5 is installed at the gap in the transition plate at the tail end of the narrow belt; the two proximity sensors 6 are respectively installed at the front and tail ends of the anti-collision bracket inside the narrow belt; the two laser rangefinders 7 are respectively installed on the left and right sides of the tail end of the narrow belt frame. The first photoelectric sensor 1, the second photoelectric sensor 2, the third photoelectric sensor 3, the fourth photoelectric sensor 4, the fifth photoelectric sensor 5, the proximity sensors 6, the laser rangefinders 7, and the display screen 8 are all electrically connected to the MCU 9. Therefore, by detecting the status of the first photoelectric sensor 1, the second photoelectric sensor 2, the third photoelectric sensor 3, the fourth photoelectric sensor 4, the fifth photoelectric sensor 5, the proximity sensor 6, and the laser rangefinder 7, it is possible to detect whether any abnormality occurs at any position of the narrow strip and trigger an alarm, so that the entire narrow strip sorting system can trigger a self-protection mode. The alarm position can be accurately displayed on the display screen 8, thereby enabling safe, accurate, and efficient fault location.
[0047] Specifically, the first photoelectric sensor 1 is used to detect whether the trolley at the position of the packing conveyor belt detaches when it flips from the lower layer to the upper layer; the second photoelectric sensor 2 is used to detect whether the trolley at the position of the lower bottom net at the front end of the narrow belt detaches when it flips from the lower layer to the upper layer; the third photoelectric sensor 3 is used to detect whether the trolley at the position of the lower bottom net at the tail end of the narrow belt detaches when it flips from the upper layer to the lower layer; the fourth photoelectric sensor 4 is used to detect whether the trolley on the transition plate at the tail end of the narrow belt has fallen off; the fifth photoelectric sensor 5 is used to detect whether the trolley at the gap position of the transition plate at the tail end of the narrow belt has fallen off; the proximity sensor 6 is used to detect whether foreign objects are attracted to the magnets at the front and tail ends of the anti-collision bracket inside the narrow belt; and the laser rangefinder 7 is used to detect whether the trolleys on the left and right sides at the tail end of the narrow belt frame are loose or have fallen off.
[0048] In this embodiment, the first photoelectric sensor 1, the second photoelectric sensor 2, the third photoelectric sensor 3, and the fourth photoelectric sensor 4 are all through-beam photoelectric sensors, and the fifth photoelectric sensor 5 is a reflective photoelectric sensor. All of these sensors operate in the L mode. Therefore, in well-lit environments, the L mode can more accurately detect changes in light, thus enabling the monitoring of whether the vehicle has detached.
[0049] Specifically, the photoelectric sensor is used to detect unexpected situations during the movement of the trolley. When the narrowband machine is running normally, the screws used to fix the trolley will not fall off. When the screws loosen, the trolley will fall off due to loss of fixation. The trolley usually falls off in a one-sided drop. When the falling surface exceeds the detection distance of the photoelectric sensor, an alarm will be triggered.
[0050] Specifically, L mode refers to Light Action mode.
[0051] In this embodiment, the system further includes a first mounting bracket 10, through which the fifth photoelectric sensor 5 is mounted at the gap of the narrow strip tail transition plate. The first mounting bracket 10 has a first mounting hole 11 and a second mounting hole 12, the second mounting hole 12 being an oblong hole. Thus, the reflector is fixed through the first mounting hole 11, and the position of the reflector is adjusted through the second mounting hole 12 to ensure that the fifth photoelectric sensor 5 functions normally.
[0052] Specifically, reflective photoelectric sensors are used to detect situations where goods or detached carts are stuck in gaps.
[0053] In this embodiment, it further includes: four second mounting brackets 13. The first photoelectric sensor 1 is mounted on the supply belt conveyor via the second mounting brackets 13; the second photoelectric sensor 2 is mounted on the lower bottom mesh at the front end of the narrow belt via the second mounting brackets 13; the third photoelectric sensor 3 is mounted on the lower bottom mesh at the tail end of the narrow belt via the second mounting brackets 13; and the fourth photoelectric sensor 4 is mounted on the transition plate at the tail end of the narrow belt via the second mounting brackets 13. The second mounting brackets 13 have a third mounting hole 14, a fourth mounting hole 15, and a fifth mounting hole 16, where the third mounting hole 14 and the fifth mounting hole 16 are both oblong holes. Thus, the positions of the first photoelectric sensor 1, the second photoelectric sensor 2, the third photoelectric sensor 3, and the fourth photoelectric sensor 4 are adjusted via the third mounting hole 14 to ensure their normal operation.
[0054] In this embodiment, the system further includes two third mounting brackets 601. Each third mounting bracket 601 has threaded mounting holes 602 for mounting the proximity sensor 6 onto it. Each third mounting bracket 601 has a baffle 603 and a rotating shaft 604. The rotating shaft 604 passes through the baffle 603 and is fixedly connected to it. Both ends of the rotating shaft 604 are rotatably connected to the third mounting bracket 601. Therefore, the distance between the proximity sensor 6 and the baffle 603 can be adjusted via the threaded mounting holes 602.
[0055] Specifically, when the magnet attracts a foreign object, it will impact the baffle 603. The rotating shaft 604 will increase the distance between the proximity sensor 6 and the baffle 603. When the increased distance between the proximity sensor 6 and the baffle 603 exceeds the preset first detection distance, a signal (i.e., the signal that the increased distance between the proximity sensor 6 and the baffle 603 exceeds the preset detection distance) is sent to the MCU9 to issue an emergency stop signal, thereby stopping the narrow strip machine sorting system.
[0056] Specifically, in actual use, the proximity sensor 6 works together with the third bracket, which is installed at the front and rear ends of the anti-collision bracket inside the narrow band. The third bracket is placed at the front of the linear motor. When the car is running, it passes the third bracket first and then the linear motor. If the magnet attracts foreign objects, the anti-collision mechanism will be triggered first, and the car will stop after running a certain distance, thus protecting the linear motor.
[0057] In this embodiment, the system further includes: two fourth mounting brackets 701, each fourth mounting bracket 701 having multiple sixth mounting holes 702 for mounting the laser rangefinder 7 onto the fourth mounting bracket 701; the fourth mounting bracket 701 also has multiple seventh mounting holes 703, which are oblong holes for mounting the fourth mounting bracket 701 to the tail end of the narrow-band frame. Thus, the illumination position of the laser rangefinder 7 can be adjusted through the seventh mounting holes 703.
[0058] Specifically, the laser rangefinder 7 is positioned downwards (i.e., the detection end of the laser rangefinder 7 is facing downwards), directly illuminating the belt surface of the trolley. A second detection distance A is preset (this distance is the actual distance from the laser displacement sensor to the belt surface; in this embodiment, A = 200 mm), and an offset data X is preset (in this embodiment, X = 5 mm) to form a detection range (AX, A+X) (in this embodiment, the detection range is (195 mm, 205 mm)). Within this range, the trolley belt surface is normal and will not trigger an alarm shutdown.
[0059] The monitoring process of the alarm system of this utility model is as follows: The narrow-band sorting system is started, and the status of each sensor (first photoelectric sensor 1, second photoelectric sensor 2, third photoelectric sensor 3, fourth photoelectric sensor 4, fifth photoelectric sensor 5, proximity sensor 6, and laser rangefinder 7) is read in real time and displayed on the display screen 8. If the sensor detection status is normal, the narrow-band sorting system operates normally; if the sensor detection status is abnormal, the narrow-band sorting system stops operating. When the narrow-band sorting system stops operating, the fault is handled. If the fault handling is completed, the narrow-band sorting system is started again, and the status of each sensor is read in real time. If the fault handling is not completed, the fault handling continues until the fault is resolved.
[0060] A narrow-band sorting system includes a sensor-based installation alarm system.
[0061] In summary, this utility model, through the status detection of the first photoelectric sensor 1, the second photoelectric sensor 2, the third photoelectric sensor 3, the fourth photoelectric sensor 4, the fifth photoelectric sensor 5, the proximity sensor 6, and the laser rangefinder 7, can detect whether there are any abnormalities at various positions of the narrow strip and trigger an alarm, so that the entire narrow strip sorting system can trigger a self-protection mode. Furthermore, the alarm position can be accurately displayed on the display screen 8, thereby enabling safe, accurate, and efficient fault location.
