Manufacturing method of bulk material conveying system:
In today's increasingly tense labor force, all kinds of enterprises urgently need automation equipment to replace manpower. This system belongs to the category of automatic material transportation and is used for automatic metering and timing and fixed-point transportation of various bulk materials (fine particles or powders). Instead of manual weighing and transportation, labor intensity is reduced, and at the same time, the spillage in the manual transportation process is avoided, and labor and raw material costs are saved for the enterprise.
Background technique:
: In printing and dyeing, chemical, leather and other types of enterprises, a large amount of materials are needed. Some of these materials are in the form of solid fine particles or powders, such as salts, alkalis and various dyes required in printing and dyeing factories, commonly known as bulk materials . These bulk materials require a very large amount, and it is inconvenient to dissolve them in water and pipe them. Otherwise, the concentration of the dye solution in the dyeing machine will be diluted, and the printing and dyeing process will be changed, which will greatly increase the cost. Some dyes are insoluble in water, and some are easy to decompose after being dissolved in water. The pipes through which the dye flows are not easy to clean. Under normal circumstances, workers frequently weigh these bulk materials with scales, and deliver them to each dyeing machine at a fixed time, fixed point and quantitative basis. There can be no mistakes in the middle, otherwise the cloth will not meet the quality requirements. The whole process is labor-intensive, cumbersome, and error-prone, and requires factory managers and workers to have a strong sense of responsibility. In view of the above situation, the present invention solves these problems well
Summary of the invention
This system consists of the following units: 1. Load-bearing guide rail with wire hanging rail 2. Electric vehicle with crane 3. Weighing device 4. Multi-grid material bucket with electromagnetic brake 5. Control console (including PLC, touch screen, relay and contact The load-bearing guide rail is made of I-steel and is erected in the air to connect the workshop and the material room. According to needs, it can be made into a straight or curved shape so that it can pass over the feeding port of each machine. The electric vehicle is installed on the guide rail and can walk on the guide rail and pass between the workshop and the material room. The multi-grid material bucket can be hung up and down by the weighing device to hang the crane. Before the system works, the electric vehicle takes the multi-grid material barrel into the material room, the crane lowers the material barrel, and the worker puts different bulk materials into the specified compartment in the material barrel, and the crane removes the material until it is full. The bucket is hoisted to the highest point. After it is stabilized, the bucket is weighed by the weighing device, and the data is transferred to the "PLC" as the initial value, which serves as the initial basis for each feeding measurement. According to the pre-established procedure, if the No. 4 material consumption unit needs material B, the amount is 7 kg, and it is required to be delivered within the specified time period. During this time period, the electric vehicle hoisted the barrel to the workshop, stopped above the feeding port of the No. 4 feeding unit, and then lowered it by the crane to a position close to the feeding port. At this time, the material B is located The electromagnetic gate below the grid is opened, and material B is drained from the gate and enters the feeding port of the No. 4 material unit. At this time, the weighing device continuously outputs data to the PLC. After 7KG is drained, the system responds, and the material B is located The electromagnetic brake is automatically closed, the feeding is stopped, and the hoist automatically hoists the bucket to the highest position, waiting for the next feeding instruction. After the various materials in the multi-grid barrel are used up, the electric vehicle will automatically enter the material room according to the procedure, put down the barrel, and remind the staff to supplement. Prepare for the next feeding. This system solves the transportation problem of fine granular bulk materials in a relatively simple way. It has the following advantages: 1. This system only needs some relatively simple equipment to perform long-distance separation of a variety of fine granular materials into time periods. Quantitative and fixed-point delivery. 2. Simple implementation and low cost. Except for multi-grid barrels, all other parts and accessories can be bought from the market, and there is no expensive thing. The processing and manufacturing of multi-grid barrels is also convenient. 3. If a workshop adopts the "liquid pipeline transportation system" at the same time, it can share a set of electrical control with this system to complete the automatic feeding of the workshop. 4. It does not occupy the area of ​​the workshop, as long as the feeding place and the place of the operation table are set in the material room, the area is small, the guide rail is overhead in the workshop, and the electric vehicle is also walking in the air while hanging the material bucket.
Detailed ways
: In a printing and dyeing factory that processes textiles, in the production process, there are two major types of chemical materials that need to be transported, one is various additives, and the other is various dyes. The salt, alkali and various dyes should be transported by this system. In the air between the workshop and the material room, erect I-steel guide rails directly above the attached cylinders (feeding positions) of each dyeing machine so that the electric vehicle can pass directly above the attached cylinders with the material barrels hanging on them. A proximity switch is installed on the guide rail at the position directly above to sense the position of the electric vehicle and send the signal to the "PLC" of the electric console. A cable hanging rail is erected next to the guide rail to suspend the cable, which can be extended or shortened with the walking of the electric vehicle. The cable gathers the electric vehicle's walking motor wire, hoist motor wire, pressure sensor device signal wire and electromagnetic brake control wire and other wires together, leading to the electric console. The electric vehicle walks on the I-steel guide rail, the attached crane is mounted with a weighing sensor device, and the barrel is hung on the device. The weight of the barrel and the materials in it are all added to it, and the weight is reflected by the output signal come out. A rotary encoder is installed on the motor of the hoist, and the signal is sent to the "PLC" of the electric operation console, and the height of the bucket can be obtained by calculating the rotation of the motor. The barrel can be designed according to the specific conditions of each printing and dyeing factory, and the total weight can be designed between 500KG and 2000KG. Design as many cells as there are kinds of materials, and determine the volume of each cell according to the usage ratio of each material. There is an electromagnetic gate under each grid. When it is opened, the material can flow down from the gate, and it stops when it is closed. In the dyeing workshop of a printing and dyeing factory, two rows of dyeing vats are generally arranged against the wall. Taking into account the load capacity of the barrel and the limitation of walking distance, two sets of such devices should be arranged in the workshop, and the electrical control system should share one set. The I-steel guide rails are erected above the attached vat of the dyeing vat, and the buckets containing salt, alkali and various dyes walk along the rails over the workshop to deliver the needed things to each dye vat regularly and quantitatively. If the liquid additive is automatically transported by pipeline, it can share a set of electrical control with this system to complete the transport of all chemical materials in the workshop. Some factories are equipped with a central main control computer room to monitor various types of machines. At this time, if communication is established between the system and the central computer to obtain the operating data of each machine, the system can become a fully automatic feeding system. If there is no central control computer room, this system can also become a semi-automatic feeding system. That is, after putting the textile into the dyeing vat, the operator sets which dyeing vat, what time, what material, and how many materials on the computer according to the specific process, and the system will complete the feeding task according to the pre-settings.
