Description

Technical Field

[0001] The invention relates to the field of yarn car cleaning devices, and in particular to a multifunctional narrow return empty conveyor line vehicle maintenance equipment. Background Art

[0002] High-quality products require a clean environment during the production process, and logistics vehicles and equipment need to be tested and maintained online to ensure the normal operation of the assembly line. The semi-finished products of glass fiber production are circulated using yarn carts, which are sent to various work points through conveyor lines to complete the process. When these yarn carts are running on the assembly line, they experience conveyor line vibration, corner rotation, lifting, high-temperature baking in the oven, robot automatic loading and unloading, etc. under load. During these processes, the yarn carts will be deformed and contaminated with "hair". When the vehicle deformation reaches a certain degree, the yarn balls installed on the vehicle tiles will slide out, causing damage to the yarn balls. The light "hair" on the vehicle will fly in the air, reducing the cleanliness of the environment and the quality of the product. If the wheel is stuck due to bearing damage or glass fiber winding, the loose connection screws will cause inflexible operation, vehicle skewness, rollover, and damage to the load.

[0003] The current technology uses a brush roller in an open space to clean the yarn car on the return line. The problem of "hairy" flying cannot be overcome, which will pollute the vehicle and the working space again, greatly reducing the effectiveness of cleaning. Another device is set up to detect the deformation of the vehicle and the tiles carrying the yarn balls, which occupies a section of the conveyor line for detection. There are problems such as a long conveyor line length and a long time consumption. Its carrying mechanism is set up at the bottom, which occupies a large space and cannot meet the compact layout requirements of intelligent manufacturing equipment. At present, the wheel jam detection is generally carried out through manual selection, which has problems such as labor consumption and untimely detection. Summary of the invention

[0004] The main purpose of the present invention is to provide a multifunctional vehicle maintenance equipment for narrow return conveyor lines. By adopting a one-machine-multi-purpose method, the length of the conveyor line is reduced. The mobile device upper structure is used to reduce the site occupation. The automatic closed space cleaning and dust collector are used to collect "hair", reduce the amount of wild wind entering, and effectively reduce the air volume of the dust collector. These measures effectively control the flying of "hair". Multiple groups of brush rollers are used to clean the entire vehicle, and the bottom is poured with concrete to improve the stability of the whole machine. The claw cylinder is used to clamp the four wheels at the same time, and a swing cylinder and a crank are set. The crankshaft changes the claw cylinder and the wheel rotation. When the wheel is stuck, the resistance is greater than the swing force of the swing cylinder, and the operation of the swing cylinder is blocked. It cannot swing in place and will not touch the magnetic sensor in place. At this time, the control system sends a command to transport the vehicle with the stuck wheel to the lane to be repaired.

[0007] Preferably, the brush roller base is vertically arranged perpendicular to the bottom surface; the multiple brush roller assemblies are arranged at one end of the brush roller base parallel to the ground; and a windshield is provided at the other end of the brush roller base.

[0008] Preferably, a dust collecting funnel is provided below the yarn car cleaning structure; and a dust outlet is provided below the dust collecting funnel.

[0009] Preferably, the yarn carriage cleaning structure is connected to a dust collector which is electrically connected to a PLC control system via a pipeline.

[0010] Preferably, the empty return conveyor belt is provided with a first yarn car position sensor and a second yarn car position sensor; the first yarn car position sensor and the second yarn car position sensor are both electrically connected to the PLC control system.

[0011] Preferably, the yarn car performance detection structure includes yarn car tile position detection and yarn car wheel jam detection; the yarn car tile position detection includes a second square cylinder, multiple position sensor groups, multiple sensor brackets and multiple sensor moving rods; the multiple sensor brackets and multiple sensor moving rods are all arranged on the equipment installation column; the second square cylinder is connected to the sensor bracket through the sensor moving rod; each sensor bracket is provided with a group of position sensor groups; the yarn car wheel jam detection includes two gripping cylinders, two cranks, a crankshaft, a crank bearing seat and a swing cylinder; the gripping cylinder is arranged on both sides of the yarn car wheel; the crankshaft is connected to the gripping cylinder; the crankshaft is horizontally arranged relative to the yarn car; two cranks are vertically connected to two ends of the crankshaft respectively; the crank at one end fixes the yarn car wheel jam detection under the return conveyor belt by connecting the crank bearing seat; the crank at the other end is connected to the swing cylinder.

[0012] Preferably, each position sensor group includes two position sensors; and the distance between the two position sensors is adjusted by an adjusting screw.

[0013] Preferably, a prefabricated concrete mounting seat for improving stability is provided below the equipment mounting column.

[0014] Preferably, a top protective cover is provided above the entire device.

[0015] The beneficial effects of the present invention are:

[0016] (1) The whole machine adopts the guide rail top design, the brush roller frame adopts the hollow structure to reduce the weight, the prefabricated concrete mounting seat is set under the installation column to improve the stability, and the thrust selection of the brush push cylinder is appropriately improved to overcome the influence of multiple brushes on gravity. This design can meet the needs of equipment installation sites in narrow and confined spaces;

[0017] (2) When the empty yarn car is cleaned, light hairiness and yarn will fly in the air, causing secondary pollution to the car and reducing the cleaning effect. This design adds movable light baffles on the top, left and right, and uses the conveyor line low plate at the bottom to form a movable closed windshield wall, so that the "hairiness" can be collected and the wild wind can be blocked, which greatly reduces the air volume of the dust collector and realizes the hairiness collection at a low cost;

[0018] (3) This time, 10 sets of brush rollers are used to clean the four-layer tiles and chassis. The brush roller frame adopts a long hole design, and the brush roller spacing is adjustable to meet the needs of changing tile spacing between the cake yarn car and the direct yarn car. This design determines the tile spacing structure during assembly, and the cost is not high. If mixed cleaning of the two yarn cars is to be achieved, it is necessary to add a spacing adjustment guide roller pair and a spacing adjustment drive mechanism (cylinder or mechanical adjustment power), and add a yarn car variety identification device, which will increase the cost of the whole machine;

[0019] (4) After the yarn car is cleaned, a linear guide pair is set above the machine, and four pairs of eight beam sensors are installed to detect whether the tile deformation exceeds 3 degrees (the specific accuracy value can be adjusted). Through the program setting of the conveyor line control system, the faulty yarn car can be moved out of the empty conveyor line and put into the repair area for disposal;

[0020] (5) When the yarn car is in long-term operation, the wheel bearings are easily damaged and stuck due to the high temperature of the load being baked in the oven, the vibration of the conveyor line, and the high humidity in the production workshop. If the car continues to run, it will overturn and the load will fall, causing losses and safety hazards. The automatic inspection of wheel jams does not require manual inspection of each car, saving labor and improving the detection accuracy and timeliness. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Furthermore, the yarn car performance detection structure includes yarn car tile position detection and yarn car wheel jam detection; the yarn car tile position detection includes a second square cylinder 18, a plurality of position sensor groups 19, a plurality of sensor brackets 20 and a plurality of sensor moving rods 21; the plurality of sensor brackets 20 and the plurality of sensor moving rods 21 are all arranged on the equipment installation column; the second square cylinder 18 is connected to the sensor bracket 20 through the sensor moving rod 21; each sensor bracket 20 is provided with a group of position sensor groups 19;

[0033] The yarn cart wheel jam detection includes two gripping cylinders 22, two cranks 23, a crankshaft 24, a crank bearing seat 25 and a swing cylinder 26; the gripping cylinder 22 is arranged on both sides of the wheel of the yarn cart 1; the crankshaft 24 is connected to the gripping cylinder 22; the crankshaft 24 is arranged horizontally relative to the yarn cart 1; the two ends of the crankshaft 24 are respectively vertically connected to the two cranks 23; one end of the crank 23 is connected to the crank bearing seat 25 to fix the yarn cart wheel jam detection under the return conveyor belt 2; the other end of the crank 23 is connected to the swing cylinder 26; each position sensor group 19 includes two position sensors; the distance between the two position sensors is adjusted by the adjusting screw 27.

[0034] Working principle: The yarn car 1 enters the windshield 13 of the yarn car cleaning device through the return conveyor line 2. When it reaches the first yarn car position sensor 16, the return conveyor line 2 stops running, and the first yarn car position sensor 16 sends a signal to the PLC control system, which issues a control instruction to make the first square cylinder 3 drive the brush roller base 5 and the brush roller assembly 6 to move, and the brush roller base 5 drives the windshield 13 to move at the same time, forming a closed space for the yarn car 1. At this time, the PLC control system issues a control instruction again to start the worm gear reducer 11 and drive the brush roller assembly 6 to rotate through the driving roller chain 12 to clean all tiles of the yarn car 1. During the cleaning of the yarn car 1, the control system also issues an instruction to start the dust collector 15 to collect the "hair" generated in the closed cleaning space through the pipeline.

[0035] After the cleaning is completed, the first square cylinder 3 runs in the reverse direction, driving the brush roller base 5, the brush roller assembly 6, and the windshield 13 to return to their original positions. After returning to their original positions, the electronic control system issues a command, and the empty conveyor line 2 continues to run forward. When the yarn car 1 runs to the position of the second yarn car position sensor 17, the empty conveyor line 2 stops running, and the PLC issues a command to make the second square cylinder 18 work, driving the sensor bracket 20 and the sensor moving rod 21 to move into the yarn car 1. The position sensor group 19 is used to detect the tile position of the yarn car 1 to determine whether the upward and downward deformation angle a of the tile exceeds the set value. The setting of the upward and downward deformation value a of the tile is achieved by adjusting the adjusting screw 27. When the a value exceeds the set value, the PLC issues a command to move the yarn car 1 to the rear end through the empty conveyor line 2, and move it out of the normal operation conveyor line through the rotating table to enter the maintenance lane for maintenance.

[0036] After the detection is completed, the sensor bracket 20 and the sensor moving rod 21 return to their original positions through the action of the second square cylinder 18. While detecting the deformation of the tile, the gripper cylinder 22 set at the bottom of the yarn car 1 clamps the two sides of the wheel of the yarn car 1. After clamping and positioning, the swing cylinder 26 drives the gripper cylinder 22 and the clamped wheel to rotate a set angle through the crank 23 and the crankshaft 24. When the wheel is damaged due to bearing damage and the glass fiber is wrapped and clamped, and its resistance is greater than the torque set by the swing cylinder 26, the swing cylinder 26 will not swing, and the control system determines that the wheel is faulty and issues a command to transport the vehicle with the stuck wheel to the lane to be repaired.
