Description
Technical Field
[0001] This utility model relates to the field of compressor cylinder manufacturing equipment technology, and in particular to a hopper mechanism for realizing automatic feeding of compressor cylinders. Background Technology
[0002] In the compressor manufacturing process, the supply of cylinder blanks has a crucial impact on the continuity and efficiency of the entire production process. Currently, in traditional production methods, cylinder feeding often uses simple storage racks, which suffer from problems such as low efficiency, large footprint, and susceptibility to damage to the cylinders. Some automated feeding devices also have poor adaptability and are difficult to match the feeding needs of cylinders of different specifications.
[0003] In view of the problems existing in the prior art, it is necessary to study and design a new type of hopper mechanism for automatic feeding of the compressor cylinder, so as to overcome the problems existing in the prior art. Summary of the Invention
[0004] The existing cylindrical feeding methods proposed above mostly use simple storage racks, which have problems such as low efficiency, large footprint, and easy damage to the cylindrical body. Some automated feeding devices have poor adaptability and are difficult to match the feeding needs of cylindrical bodies of different specifications. Therefore, a silo mechanism is provided to realize automatic feeding of compressor cylindrical bodies, which ensures the continuity and efficiency of the compressor cylindrical body production process, while reducing manual intervention and lowering costs.
[0005] The technical means adopted in this utility model are as follows:
[0006] A hopper mechanism for automatically feeding the compressor cylinder includes: a frame, a tail plate, a non-powered roller conveyor, a transition roller conveyor, a powered roller conveyor, a material distribution roller conveyor, and a material picking position;
[0007] Furthermore, the unpowered roller conveyor, the transition roller conveyor, the powered roller conveyor, and the material distribution roller conveyor are arranged sequentially from one end of the frame to the other.
[0008] Furthermore, the tail plate is detachably mounted on one end of the frame near the unpowered roller conveyor;
[0009] Furthermore, the material taking position is detachably mounted on the material taking position mounting base at one end of the frame near the material distribution roller conveyor.
[0010] Furthermore, the frame consists of two parts: a non-powered section frame and a powered section frame, which are connected and fixed by connecting plates on the left and right sides.
[0011] Furthermore, the frame of the non-powered section is designed with an inclination, and the inclination is adjusted according to the downward force of the cylinder, so that the cylinder can slide freely to the powered roller conveyor without hitting / scratching the cylinder on the powered section roller conveyor.
[0012] Furthermore, the power section frame is designed horizontally, which facilitates the removal of the cylinder in the next process.
[0013] Furthermore, the tail plate is fixed to the rear of the non-powered section frame with screws. The surface of the tail plate is made of SUS304 stainless steel plate, which has strong impact resistance and wear resistance. The cylinder is manually moved to this position to wipe and inspect the cylinder. After that, the cylinder is pushed onto the non-powered roller conveyor.
[0014] Furthermore, the unpowered roller conveyor sits on the unpowered section frame and consists of four roller conveyors separated by partitions;
[0015] Furthermore, the unpowered roller conveyor uses deep groove ball bearings 6002zz and hardened chrome-plated rods as rolling shafts, which have low resistance and high hardness, reducing friction between the rolling shaft and the end face of the cylinder, and utilizing the weight of the cylinder to roll down, reducing the length of the power section and lowering energy consumption.
[0016] Furthermore, the transition roller conveyor sits on the unpowered section frame, and its roller conveyor section consists of 4 long hardened chrome-plated bars and deep groove ball bearings 6002zz;
[0017] Furthermore, a sprocket is installed on one side of the hardened chrome-plated rod, which drives the chain through an adjustable speed motor M590-502+5GU-30K mounted on the frame. This allows for connection between unpowered and powered roller conveyors, enabling the cylinder to transition slowly and preventing it from tipping over.
[0018] Furthermore, the powered roller conveyor sits on the powered section frame, with both sides fixed to the powered section frame, adjacent to the transition roller conveyor, and receives the cylinder conveyed by the transition roller conveyor;
[0019] Furthermore, the powered roller conveyor section consists of 12 long hardened chrome-plated bars and deep groove ball bearings 6002zz. A sprocket is mounted on one side of the hardened chrome-plated bars, and the beginning and end of the rollers on the sprocket side are connected by unpowered sprockets as chain transitions. The chain is driven by an adjustable speed motor M590-502+5GU-30K mounted on the frame to rotate the rollers, so that the rollers are conveyed forward at a uniform speed.
[0020] Furthermore, four partitions are installed on the powered roller conveyor;
[0021] Furthermore, the four partitions on the powered roller conveyor are connected to the four partitions on the unpowered roller conveyor via connecting blocks to ensure stable material supply.
[0022] Furthermore, the material distribution roller conveyor is located on the powered section frame, serving as the last roller conveyor, situated between the powered roller conveyor and the material pick-up position;
[0023] Furthermore, the roller section of the material distribution roller conveyor consists of four long, hardened chrome-plated bars and a deep groove ball bearing 6002zz. A sprocket is mounted on one side of the hardened chrome-plated bar, which is driven by a variable speed motor M590-502+5GU-30K mounted on the frame. It works in conjunction with the material handling position to separate the first row of cylinders from the rear row of cylinders, preventing scratches during handling.
[0024] Furthermore, the material handling position includes: a cylinder, a guide rail, a proximity sensor, and a limit plate;
[0025] Furthermore, the guide rail adopts the HIWIN / EGH25CA1R170ZBCⅡ standard guide rail. The guide rail track is fixed on the material picking position mounting base, and the upper part of the slider is fixed to the lower end of the limit plate, which plays the role of supporting the limit plate and guiding and positioning.
[0026] Furthermore, the cylinder adopts the Japanese SMC / CDG1LN40-70Z-A93 standard cylinder. The cylinder body is screwed onto the material picking position mounting seat. The piston rod and the limit plate are connected by a floating connection. The cylinder action will drive the limit plate to move forward and backward.
[0027] Furthermore, the limiting plate is equipped with four V-shaped material picking positions, which are used to position the cylinder by positioning the circular object using the V-shape; the material distribution roller conveyor transports the cylinder to the limiting plate, and the V-shaped material picking positions at the limiting plate can automatically guide the cylinder to the correct position;
[0028] Furthermore, the sensor uses a Keyence EV-118M proximity sensor, installed at the rear of the V-shaped material handling position, which can detect whether there is a cylinder at this position, facilitating automatic operation in the next process.
[0029] Furthermore, the hopper mechanism that enables automatic feeding of the compressor cylinder is also equipped with a cylinder monitoring device installed on both sides of the roller conveyor to monitor the number of compressor cylinders. When the number of cylinders is lower than the preset value, an alarm device is triggered to remind manual replenishment of cylinders, ensuring the continuity of cylinder supply.
[0030] Furthermore, the control system uses PLC to control the material distribution and conveying actions, and is linked with the main control system of the production line to achieve fully automatic material feeding.
[0031] The working process of this utility model is as follows:
[0032] After the cylinder is processed in the previous step, it is placed on the tail plate. After wiping and inspection, it is pushed onto the unpowered roller conveyor. The cylinder slides forward along the unpowered roller conveyor under its own weight to the transition roller conveyor. The motor on the transition roller conveyor drives the rollers to rotate continuously, correcting the cylinder's posture and reducing its downward speed. Finally, the stabilized cylinder is transported to the powered roller conveyor. The motors of the powered roller conveyor and the distribution roller conveyor rotate together, transporting the cylinder to the sensor position and stopping after a certain delay. Then, the picking position retracts to its original position, and the distribution roller conveyor motor starts independently, rotating the cylinder back to the sensor position before stopping. Finally, it waits for the robot to pick up the cylinder.
[0033] When the material handling equipment is working normally, the cylinder extends and drives the limit plate forward, pushing all the cylinders out of their original positions and then retracting them; at this time, the material distribution roller conveyor starts, driving the row of cylinders in its position forward to the limit plate position; at this time, the first row of cylinders is separated from the second row of cylinders. The end of the limit plate is V-shaped, which can guide and position the cylinders, making it convenient for automated clamping. There is a proximity sensor on the limit plate to detect whether there are cylinders at the material handling position.
[0034] Compared with the prior art, the present invention has the following advantages:
[0035] 1. The hopper mechanism provided by this utility model realizes automatic feeding of compressor cylinders. After the hopper mechanism buffers a certain amount of cylinders, it can balance the production rhythm of the front and rear equipment. When the current process is under maintenance or abnormal, the rear equipment can still produce. When the rear equipment is abnormal, the cylinders produced by the front process are buffered in the hopper mechanism, and the equipment production will not be interrupted.
[0036] 2. The hopper mechanism provided by this utility model realizes automatic feeding of the compressor cylinder. The hopper mechanism automatically feeds the cylinder. After the cylinder feeding is stable, the rear equipment can be automated and robots can be used to replace manual labor, saving costs.
[0037] 3. The hopper mechanism for automatic feeding of the compressor cylinder provided by this utility model has a V-shaped structure at the end, and the product positioning accuracy is within ±0.1, which is 50% higher than the traditional accuracy.
[0038] 4. The hopper mechanism for automatic feeding of the compressor cylinder provided by this utility model has rollers that directly contact the cylinder without a bottom support plate, which can effectively prevent foreign objects from sticking to the end face of the cylinder.
[0039] In summary, the technical solution of this utility model solves the problems of low efficiency, large footprint, and easy damage to the cylinder caused by the simple storage racks used in the existing cylinder feeding technology, and the difficulty of matching the feeding needs of cylinders of different specifications due to poor adaptability of some automated feeding devices.
