Abstract
Description
Technical Field
[0001] This application relates to the field of dimensional inspection equipment, and in particular to a device for detecting the height and width of raw materials entering the warehouse. Background Technology
[0002] With the development of manufacturing and logistics, the level of automation is constantly improving, and the size control of raw materials is becoming increasingly stringent. Current inbound inspections mostly rely on manual visual inspection or traditional fixed measuring tools. These methods are inefficient, prone to false positives and false negatives, and cannot meet the modern requirements for high efficiency and precision.
[0003] A related technology discloses an object width and height detection device, comprising a conveyor track mounted on the ground, with a gantry frame mounted on the outside of the conveyor track. Laser sensors electrically connected to a control system are arranged on the top and sides of the gantry frame. Workers place materials, along with a loading platform, onto the conveyor track using a forklift or direct handling. During the transfer of materials to the warehouse, they pass through the gantry frame. During this process, multiple laser sensors on the gantry frame work together to detect the width and height of the materials.
[0004] However, when the material volume is small, the distance between the laser sensor and the material is relatively far, which may lead to missed detections or false detections, resulting in poor detection accuracy and obvious shortcomings. Utility Model Content
[0005] To improve measurement accuracy, this application provides a device for detecting the height and width of raw materials entering the warehouse.
[0006] The technical solution of the raw material warehousing height and width detection device provided in this application is as follows:
[0007] A raw material warehousing height and width detection device includes side slide rails arranged perpendicular to a conveyor track on both sides. Vertical uprights are slidably arranged on both side slide rails, and a first compression spring supports the uprights at the ends of their respective side slide rails closest to the conveyor track. A horizontal intermediate beam is erected between the two uprights, with collinear sliding beams slidably passing through both ends of the intermediate beam. Vertical lifting grooves are formed on the uprights, and the ends of the sliding beams extend into and slide within the lifting grooves. Reversing wheels are arranged on both uprights, and fixed rings are arranged at opposite ends of the two side slide rails. A first winch motor, electrically connected to a control system, is arranged on the ground. The wire rope of the first winch motor passes through the nearest fixed ring, then around each reversing wheel and is tied to a fixed ring farther away. A drive assembly for driving the intermediate beam to rise and fall is also arranged between the tops of the two uprights. Laser sensors, electrically connected to the control system, are arranged on both the uprights and the intermediate beam.
[0008] By adopting the above technical solution, the control system starts the first winch motor, which winds up its wire rope. Under the tension of the wire rope, the two uprights move closer to each other. During this process, the sliding beam is pushed back into the middle beam by the corresponding upright, and the drive assembly can also drive the middle beam to rise and fall. This allows the position of each laser sensor to be adjusted, thereby reducing the distance between the laser sensor and the material, which helps to reduce the possibility of missed detection and false detection.
[0009] Optionally, a buzzer alarm electrically connected to the control system is arranged on the pole.
[0010] By adopting the above technical solution, when the laser sensor detects that the distance between it and the material is too small, the buzzer alarm will sound to remind the operator.
[0011] Optionally, a second compression spring is provided between the end of the slide beam of the slide bar located in the lifting groove and the top of the lifting groove.
[0012] By adopting the above technical solution, the two second compression springs work together to push the middle beam and the two sliding beams to descend synchronously, reducing the possibility of tilting during the descent process.
[0013] Optionally, a bearing plate is slidably arranged in the lifting groove below the sliding beam. The laser sensor on the upright is located on the bearing plate. A screw rod is arranged on the bearing plate and extends to the opposite sides of the two uprights. A stop plate is slidably sleeved on the screw rod. A fastening nut for pressing the stop plate against the upright is threaded on the screw rod. A clearance groove is vertically opened on the upright to allow the screw rod to move freely during lifting.
[0014] By adopting the above technical solution, workers can manually adjust the position of the corresponding laser sensor by loosening the fastening nut, thereby improving the accuracy of laser sensor detection.
[0015] Optionally, the carrier plate is coated with polytetrafluoroethylene.
[0016] By adopting the above technical solution, polytetrafluoroethylene has a low coefficient of friction, which helps to improve the smoothness of the lifting and lowering of the support plate on the pole.
[0017] Optionally, the drive assembly includes a slide that slides with the top of the pole, and a second winch motor electrically connected to the control system is arranged on the slide, with the wire rope of the second winch motor connected to the intermediate beam.
[0018] By adopting the above technical solution, the control system starts the second winch motor, which winds up and unwinds the wire rope, thereby enabling the intermediate beam to drive the corresponding laser sensor to lift and lower.
[0019] Optionally, an elastic rope is attached between the corresponding ends of the upright and the carriage, and the distance between the two elastic ropes gradually decreases from top to bottom.
[0020] By adopting the above technical solution, multiple elastic pull ropes can be used to automatically position the second winch motor on the slide, reducing the possibility of measurement errors caused by the lateral deviation of the second winch motor.
[0021] Optionally, a pressure plate is bolted to the top of the upright, and an inverted U-shaped mounting groove is arranged on the pressure plate, through which the carriage slides.
[0022] By adopting the above technical solution, the pressure plate presses the carriage tightly onto the top of the upright, making disassembly and assembly convenient.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] 1. The control system starts the first winch motor, which winds up its wire rope. Under the tension of the wire rope, the two uprights move closer to each other. During this process, the sliding beam is pushed back into the middle beam by the corresponding upright. The drive assembly can also drive the middle beam to rise and fall, thereby adjusting the position of each laser sensor and reducing the distance between the laser sensor and the material, which helps to reduce the possibility of missed detection and false detection.
[0025] 2. After loosening the fastening nuts, workers can manually adjust the position of the corresponding laser sensor, thereby improving the accuracy of laser sensor detection;
[0026] 3. Multiple elastic pull ropes work together to automatically position the second winch motor on the carriage, reducing the possibility of measurement errors caused by the lateral deviation of the second winch motor. Attached Figure Description

[0030] The following is combined with Figure 1-2 This application is described in further detail.
[0031] This application discloses a device for detecting the height and width of raw materials entering the warehouse.
[0032] Reference Figure 1 The raw material warehousing height and width detection device includes side slide rails 2 arranged on both sides of the conveying track 1 and perpendicular to it. Each side slide rail 2 has a vertically slidable upright rod 3. A laser sensor 10 electrically connected to the control system is arranged on the upright rod 3. A first compression spring 4 supports the upright rod 3 and the end of the side slide rail 2 near the conveying track 1. The two upright rods 3 are symmetrical about the conveying track 1.
[0033] Reference Figure 1 A horizontal intermediate beam 5 is erected between the two uprights 3. A laser sensor 10 is also bolted to the bottom of the intermediate beam 5. Both ends of the intermediate beam 5 are slidably connected with collinear sliding beams 6. A vertical lifting groove 31 is opened on the upright 3. The end of the sliding beam 6 extends into the lifting groove 31 and slides with it. A second compression spring 12 supports the end of the sliding beam 6 located in the lifting groove 31 between the top of the lifting groove 31 and the top of the lifting groove 31.
[0034] Reference Figure 1 Multiple reversing wheels 7 are bolted to the two uprights 3. The opposite ends of the two side slide rails 2 are threaded with fixing rings 8. The first winch motor 9, which is electrically connected to the control system, is bolted to the ground by expansion bolts. The wire rope of the first winch motor 9 passes through the fixing ring 8 that is close to it, and then passes around each reversing wheel 7 in turn and is tied to the fixing ring 8 that is farther away from it.
[0035] Reference Figure 1 The control system starts the first winch motor 9, and the wire rope of the first winch motor 9 is wound up. Under the tension of the wire rope, the two uprights 3 move closer to each other, thereby adjusting the distance between the laser sensor 10 on the uprights 3 and the material. During the process, the uprights 3 push the corresponding sliding beam 6 back into the middle beam 5.
[0036] Reference Figure 1 A bearing plate 13 is slidably arranged in the lifting groove 31 below the sliding beam 6. The laser sensor 10 on the upright 3 is bolted to the bearing plate 13. A screw 14 is integrally formed on the bearing plate 13 and passes through to the opposite sides of the two uprights 3. A stop plate 15 is slidably sleeved on the screw 14. A fastening nut 16 for pressing the stop plate 15 against the upright 3 is threaded on the screw 14. A clearance groove 32 is vertically opened on the upright 3 to allow the screw 14 to be raised and lowered.
[0037] Reference Figure 1Workers can manually slide the support plate 13 up and down to flexibly adjust the height of the laser sensor 10 measuring station on the upright 3, thus making it suitable for measuring the width of materials of different heights.
[0038] Reference Figure 1 The support plate 13 is coated with polytetrafluoroethylene (PTFE). PTFE has a low coefficient of friction, which helps improve the smoothness of manual adjustment of the laser sensor 10 by the worker.
[0039] Reference Figure 1 Between the tops of the two uprights 3, a drive assembly for driving the intermediate beam 5 to rise and fall is arranged. The drive assembly includes a carriage 17 and a second winch motor 18 bolted to the carriage 17. The second winch motor 18 is electrically connected to the control system.
[0040] Reference Figure 1 and Figure 2 The carriage 17 includes two round rods 171 and a fixing plate 172 welded between the two round rods 171. A pressure plate 20 is bolted to the top of the upright 3. Two inverted U-shaped mounting grooves 201 are arranged on the pressure plate 20. The two round rods 171 correspond one-to-one with the two mounting grooves 201 on the pressure plate 20, and the round rods 171 slide through the mounting grooves 201.
[0041] The bottom of the fixed plate 172 is bolted with a second winch motor 18 that is electrically connected to the control system. The wire rope of the second winch motor 18 is tied at the midpoint of the top length of the intermediate beam 5.
[0042] Reference Figure 1 An elastic rope 19 is attached between the corresponding ends of the upright pole 3 and the round pole 171, and the distance between the two sets of elastic ropes 19 gradually decreases from top to bottom.
[0043] As the upright 3 slides on the side rail 2, the elastic pull rope 19 is stretched. The two sets of elastic pull ropes 19 work together to ensure that the second winch motor 18 is located in the center position between the two uprights 3, thereby reducing the possibility of measurement error caused by the lateral deviation of the second winch motor 18.
[0044] Reference Figure 1 The control system starts the second winch motor 18, which winds up and unwinds the wire rope. This allows the intermediate beam 5 to drive the corresponding laser sensor 10 to rise and fall, further improving the applicability and accuracy of measuring the width and height of materials of different volumes.
[0045] Reference Figure 1 One of the uprights 3 is attached to a buzzer alarm 11 that is electrically connected to the control system. When the laser sensor 10 detects that the distance between it and the material is too small, the buzzer alarm 11 will sound an alarm to remind the operator.
[0046] The implementation principle of the raw material warehousing height and width detection device in this application embodiment is as follows:
[0047] The control system starts the first winch motor 9, and the wire rope of the first winch motor 9 is wound up. Under the tension of the wire rope, the two uprights 3 move closer to each other, thereby adjusting the distance between the laser sensor 10 on the uprights 3 and the material. The worker manually slides the support plate 13 up and down, thereby flexibly adjusting the height of the measuring station of the laser sensor 10 on the uprights 3.
[0048] The control system starts the second winch motor 18, which winds up and unwinds the wire rope, thereby raising and lowering the laser sensor 10 on the intermediate beam 5. This application can flexibly adjust the position of each laser sensor 10, thereby reducing the distance between the laser sensor 10 and the material, which helps to reduce the possibility of missed detection and false detection.
[0049] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
