Graduation Project Three dimensional warehouse Is the stepper motor the same as the push crane?

"Stacker" and "stepper motor" are not things on the same level at all, just like "car" and "diesel engine" are not the same thing. The stacker crane is a kind of machine used in warehousing to pick up and release goods, there are manual and automatic, the PLC design three-dimensional warehouse you said should be controlled by PLC programming stacker and the like; The stepper motor is a kind of motor, and the transmission unit of the stacker crane can be made of a stepper motor, just like the engine of an "off-road vehicle" is a "diesel engine", so the stacker crane and the stepper motor cannot be compared at the same level.

The stepper motor is generally driven by pulses, and the number of steps can be controlled by pulses, so as to accurately control the displacement, and there are special drive chips and drive modules (the small stepper motor drive that has been used in Leisai can be controlled very finely, and the step subdivision can be more than 1/10,000, that is, the accuracy can be controlled separately to control the rotation of the stepper motor by 1/10,000).

I would like to ask what is the difference between picking up and releasing goods with a stacker crane and using a stepper motor? The stepper motor can be an integral part of the stacker, but the stacker crane can use another motor instead of the stepper motor.

I don't know what the stacker crane and the stepper motor look like, but they all feel like they can do the same thing.

If the functionality is the same or similar, what is the difference in the process of writing the program? Take a look at the encyclopedia [Stacker].

According to the requirements of use, there are various types of stackers, which can generally be classified as follows:

1.Classified by support method.

Floor-supported stacker.

It is not possible to select without detailed parameters.

Also, why would you want to use a stepper motor? Do you want to do without the sensors associated with position detection? If so, I advise you not to...

Depending on where you use it, you need to drive the equipment specifically, and the automated three-dimensional warehouse uses DC motors and stepper motors.

Part drawings, assembly drawings. There are also component drawings. There may not be a lot of part drawings among them. There are mainly many structural diagrams. Because it's almost all made of steel.

The following is the difference between a three-dimensional warehouse and an ordinary warehouse:

The structure is more complex.

The design structure of the three-dimensional warehouse is very complex, because of its many functions, and the supporting equipment is also very much, so the construction of a three-dimensional warehouse requires a lot of investment, and the requirements of its construction technology are also very strict. Compared with the three-dimensional warehouse, the traditional warehouse construction is much reduced, without excessive requirements and diverse functional settings.

2.The shelves are in accordance with high precision.

Because most of the three-dimensional warehouses use high-rise shelves, but the high-bay racks have been greatly improved according to the accuracy compared with the traditional shelves, because the goods storage of high-rise shelves uses a mechanical arm to carry out storage operations, and will operate according to the procedures set by the operator in advance. Therefore, the installation accuracy of high-rise shelves is very high, and there can be no slightest error, otherwise it is easy to lead to problems such as inappropriate position of cargo storage shelves.

3.Personnel requirements are high.

Because the structure of the three-dimensional warehouse is more complex and the functions it provides, the technical requirements for the relevant operators are also higher. Only professionally trained personnel are qualified for warehouse operation positions. In contrast, the traditional warehouse does not require such a high technical quality of personnel, and in most cases it is just a simple handling and placement of goods.

4.Flexibility is large and can be adjusted in a timely manner.

Compared with traditional warehouses, three-dimensional warehouses have greater flexibility in the storage of goods, and can be adjusted in a timely manner according to the actual situation. For example, in a certain peak logistics period, the warehouse needs a large amount of goods circulation and transshipment, and the traditional warehouse is difficult to adapt to the circulation of large quantities of goods due to its loose operation process and complexity.

However, the three-dimensional warehouse solves this problem very well, not only the high-rise shelves can store a larger amount of goods, but also its mechanized operation can carry out goods access and handling operations for a long time, ensuring that a large number of goods circulation needs can be digested within a certain time limit.

There are other warehouse-related questions that you can continue to ask.

Due to the rapid increase in the cost of land in the country, if you want to store as many goods as possible in the same area, then you can only develop to a high level;

Three-dimensional warehouse generally refers to the automated three-dimensional warehouse, which is automatic access to goods by automated equipment, so as to achieve informatization, convenient management and high degree of automation;

Ordinary warehouses generally refer to forklift warehouses, where goods are accessed manually through forklifts;

The three-dimensional warehouse can be very high, generally recommended 24 meters high, and the ordinary forklift garage is generally high meters;

If the same amount of goods is stored, the investment in the three-dimensional warehouse is less than that of the ordinary forklift warehouse, because the land cost is too high.

The automated three-dimensional warehouse is referred to as the three-dimensional warehouse, which is a perfect combination of higher-end warehouse storage equipment, modern information processing technology and high-end storage equipment. The main body of the three-dimensional warehouse is composed of shelves, roadway stacking cranes, inbound (out) warehouse workbenches and automatic inbound (out) and operation control systems.

The difference with ordinary warehouse shelves is that the shelves are buildings or structures with steel structures or reinforced concrete structures, and the shelves are standard size cargo space in the shelves, and the roadway stacking crane travels through the roadway between the shelves to complete the work of storage and pick-up. Computer and barcode technology are used in management.

From the leading industry technology, high-quality equipment quality, perfect after-sales service and high-precision scientific research team, this has created Newamstar Filling Machine "Pilot Technology, Innovation China".

The intelligent warehousing system can complete the automatic storage and retrieval of unit goods under the control of the computer system, and use the cooperation of automatic storage equipment and computer management system to realize the rationalization of the high-rise placement of the three-dimensional warehouse, so as to reduce errors, speed up the rhythm of access to goods, and improve operation efficiency; Improve space utilization, reduce inventory, and save land investment costs; Reduce labor intensity, improve the working environment of workers, and reduce labor costs; Realize the overall optimization of the system, improve the production efficiency and modern management level of the enterprise. At the same time, improve customer satisfaction and achieve fast and reliable traceability of food safety.

The system can be upgraded on the basis of the existing warehouse, operate independently, or be connected to the packaging production line.

The system consists of the transit and storage of goods - high-rise shelves, pallets, containers.

Inbound and outbound operation equipment - stacker.

Inbound and outbound distribution systems – rollers, chain conveyors, distribution carts, lifts, etc.

WCS control system - including computer-controlled inbound and outbound equipment, distribution system and all electronic control devices of various testing and insurance institutions.

WMS warehouse management system - warehouse account management, data analysis, reasonable management of cargo location, equipment operation and inventory status status display, etc.

As far as Newamstar intelligent three-dimensional warehouse is concerned, the difference between intelligent three-dimensional warehouse and traditional warehouse is that it can reduce errors; improve operational efficiency; improve space utilization; Save land investment costs; improving the working environment for workers; Reduce labor costs; Achieve overall system optimization; Improve the production efficiency and modern management level of enterprises.

The advantages of automated three-dimensional warehouse are multifaceted, and for enterprises, they can be reflected in the following aspects:

1. Save the floor space of the warehouse, so that the space of the warehouse can be fully utilized. Because the automated three-dimensional warehouse adopts the assembly of large storage shelves, and the automatic management technology makes the goods easy to find, the construction of the automated three-dimensional warehouse covers a smaller area than the traditional warehouse, but the space utilization rate is large. In developed countries, improving the utilization rate of space has been taken as an important assessment index of system rationality and advancement.

In advocating energy conservation and environmental protection today, the automated three-dimensional warehouse has a good effect in saving land resources, and it is also a major trend in the future development of warehousing.

Second, automatic management has improved the management level of the warehouse. The automated three-dimensional warehouse uses computers to carry out accurate information management of goods information, which reduces the errors that may occur in the storage of goods and improves work efficiency. At the same time, the three-dimensional automated warehouse realizes motorization in the transportation of goods in and out of the warehouse, and the handling work is safe and reliable, reduces the damage rate of the goods, and can also make some goods with special requirements for the environment through special design to have a good preservation environment, such as toxic and explosive goods, and also reduces the harm that people may suffer when handling goods.

3. Automated three-dimensional warehouse can form an advanced production chain and promote the progress of productivity. Professionals pointed out that due to the high access efficiency of the automated three-dimensional warehouse, it can effectively connect the production links in the warehouse and form an automated logistics system in storage, so as to form a planned and arranged production chain, so that the production capacity has been greatly improved.

Disadvantages of automated three-dimensional warehouse.

1) The structure is complex, and there are many supporting equipment, which requires a lot of infrastructure and equipment investment.

2) A large amount of steel should be used for high-rise shelves, and the installation accuracy of shelves is high, and the construction is more difficult, and the construction period is long.

3) Once the control system fails, the entire warehouse will be paralyzed, and the sending and receiving operations will be interrupted.

4) The variety of stored goods is limited to a certain extent, and a separate storage system must be set up for large and bulky goods.

5) The quality requirements for warehouse management and technical personnel are high, and they must be trained to be competent.

The main advantages of automated three-dimensional warehouse:

1) All warehouse operations are mechanized and automated.

2) The use of high-rise shelves and three-dimensional storage can effectively use space, reduce floor space, and reduce land purchase costs.

3) The use of pallets or containers to store goods, the damage rate of goods is significantly reduced.

4) The cargo location is centralized, which is convenient for control and management, especially the use of electronic computers, which can not only realize the automatic control of the operation process, but also carry out information processing.

Disadvantages of automated three-dimensional warehouse.

1) The structure is complex, there are many supporting equipment, and the required infrastructure and equipment investment is high.

2) The installation accuracy of the shelf is high, the construction is more difficult, and the construction period is long.

3) The variety of stored goods is subject to certain restrictions, and a separate storage system must be set up for large and bulky goods and goods requiring special storage conditions.

4) The requirements for warehouse management and technical personnel are high, and they must be trained to be competent.

5) High process requirements, including process design before the construction of the library and operation according to the process design during production.

6) The elasticity is small, and it is difficult to cope with the peak demand of storage.

7) It is necessary to pay attention to the custody and maintenance of the equipment and maintain a long-term relationship with the equipment provider.

8) Because the automated warehouse wants to give full play to its economic benefits, it must be combined with the procurement management system, distribution management system, sales management system and other consulting systems, but the construction of these management consulting systems requires a lot of investment.

1. The whole workflow can be done with steps. You can write one step at a time for each action.

2. The emergency stop can be completed with the main control (command MC and MCR are used together) 3, if the program wants to be perfected, you can initialize it at the beginning of the program. M8002 is recommended

Anyway, I'm going to have to try it myself. It's been so many years, give yourself an explanation.

It's a very simple procedure.,But,Through your content description,It doesn't seem to be a 3x4 warehouse automatic storage.,It's manually put into the specified "third column of the first layer、The third column of the second layer、The third column of the third layer.。。 In this case, it will be easier to program the program, call me, and I'll get you ......

It is not the same as the automated warehouse, which refers to the operation of the warehouse, which is not necessarily a three-dimensional warehouse. Automated three-dimensional warehouse refers to a shelf system, a stacking system, an automatic sorting system, etc.

In a general sense, these two names are the same. Strictly speaking, it is not exactly the same, for example, the warehouse has a conveyor line and sorting, but there is no automated three-dimensional warehouse, is it considered an automated warehouse?
