Pneumatic logistics conveyor system: fast transmission speed, for the smaller volume, lighter weight materials (such as prescription lists, small boxes of medicines, a small number of specimens) has the advantage of conveying, in the field of hospitals are widely used. Rail trolley logistics conveying system: Compared with the pneumatic logistics conveying system, the weight of conveyed materials increases, and can also convey larger volume of materials (such as large boxes of drugs, etc.). However, its individual trolley by the track limitations of the width can not do too wide, each car load can not be more than 15kg, rail trolleys can not be removed from the track, conveying materials need to be manually transported to the starting station will be loaded into the trolley, a single trolley cost is high, these problems also restrict the rail trolley logistics conveying system in the application of modern hospitals. Automatic Guided Vehicle (AGV) conveying system: the advantage is that it can convey large quantities of heavy materials, but the price of a single guided vehicle is high, the system operating environment must not be too much traffic, system security and other practical problems are also its application in hospitals need to be resolved. Box-type logistics conveyor system: can meet the vast majority of material transportation needs of hospitals, but the entire system requirements are best implemented in new or expanded hospitals, the entire system equipment occupies a certain amount of space in the hospital, not all of the hospital site are suitable for setting up logistics stations and other issues, but also need to use the hospital to consider.
Pneumatic conveying system has German Eurotech invented, more than 40 years after the popularity of the world. Principle of hospital pneumatic logistics conveyor system is a use of air compressors to extract or compress the air in the pipeline, resulting in a pressure difference in the pipeline, to transport the transfer bottle with the transfer of materials, materials from the starting site to the destination site of the conveyor system.
Medical pneumatic logistics transmission system generally consists of receiving and dispatching workstations, pipe commutator, wind direction switcher, transmission bottles, logistics pipelines, air compressors, central control equipment, control networks and other equipment. Figure 2 for a hospital's pneumatic logistics transfer system diagram.
Pneumatic logistics conveying system because the power mainly relies on the differential pressure in the pipeline, so the entire system of pipeline containment requirements are very high, the system maintenance of professional requirements.
02Scope of application
Pneumatic logistics conveying system is limited by the capacity of the equipment, the logistics transfer bottle can not be made very large, so the pneumatic system conveying materials are mainly medicines, prescriptions, cases, specimens, documents, and other kinds of small items that can be loaded into the transfer bottle.
03Main features
1. Suitable for rapid delivery of goods from a single department.
2. The transmission speed of the transfer bottle is fast, reaching 5-8 meters/second.
3. Load capacity is 5~8 kilograms.
4. Suitable for the rapid transfer of small quantities of small items. Mainly used in small emergency rapid transfer of small items, intraoperative section, emergency drugs, infusion, specimens, ICU-level operating room emergency supplies.
Rail trolley conveying system, rail trolley logistics conveying system is a kind of logistics conveying system that lays a track under the hospital floor, and conveys materials from the starting station to the destination station through the trolley running on the track. The trolley on the track is suspended on the track, and the trolley is driven by the suspension wheel on the trolley to move in the horizontal and vertical direction.
On-rail trolley logistics conveying system generally consists of receiving and dispatching workstations, intelligent rail loaded trolleys, logistics track, rail turntable, automatic isolation door, center control equipment, control network and other equipment. Figure 3 for a hospital track trolley logistics delivery system logistics receiving and sending workstations.
02 Scope of application
The rail trolley logistics system has been used abroad for more than 40 years, and can be used to load relatively heavy weight and volume of large items, generally loaded weight up to 10-30 kg, can be transported in bulk to the hospital infusion, test specimens, supply room supplies, etc.. But by the limitations of the width of the track, the maximum width of the rail loaded trolley box width can only be comparable with the track width, so the width is greater than the rail trolley materials can not be transported. In the 1980s, the hospital logistics transmission field gradually appeared in the case of the rail trolley logistics transmission system used, the efficiency of the pneumatic logistics transmission system has improved. Its main features are:
1. The rail car as a carrier can be realized point to point transmission.
2. Flexible installation space.
3. Load capacity is 15~30 kilograms.
The most famous box-type logistics conveying system is from the European brand Marit, the principle of box-type logistics conveying system is a kind of transport materials into the large-capacity crate, through the crate in the material transportation starting station and material transportation destination station back and forth to achieve the purpose of material transportation of the new hospital intelligent logistics conveying system. The main equipment of the box-type logistics conveying system consists of horizontal conveying equipment, vertical conveying equipment and auxiliary equipment. In the operation of the system, it is only necessary for the staff to put the crates with conveyed materials into the entrance equipment at the starting station, and the crates will be automatically conveyed to the equipment at the destination station. The whole process does not require manual operation to enter the starting station, and the logistics system is docked with the hospital's HIS, realizing the informationization of material conveying and docking.
02Scope of application
The crate logistics system can convey infusion drugs (I.V.), medicines, specimens, surgical instruments, sterile supplies, disinfection kits, quilts, logistical supplies and other hospital materials. The basic hospital materials that can be loaded into the crate can be automatically transported, which can solve 90% of the material transport tasks in the hospital. The box-type logistics conveyor system was initially applied to tobacco, postal service, books, medicine and other logistics automation conveying, and has been applied for more than 40 years in China with mature technology. Medium-sized box-type logistics conveyor system is generally recognized as a more scientific way of transferring goods in the hospital because of its advantages in transferring weight and transmission method. Its main features are:
1. Single box weight up to 50 kilograms.
2. Continuous transmission, efficiency up to 1000 boxes / hour.
3. The carrier state is always horizontal during transportation.
4. A variety of carriers to meet the transportation requirements of different sections.
5. It can well solve the problem of centralized transmission of large-volume materials.
Liberation Army General Hospital new outpatient building reconstruction, also will be box logistics conveying system applied to the new outpatient building. Box-type logistics conveying system in the above two hospitals into operation, the application of better feedback, for large hospitals to provide a new type of material transportation automation conveyor program.
The construction of the box-type logistics conveying system is suitable for use in new or expanded hospitals, the system is realized between different floors of the material conveyance is similar to the elevator through the vertical sorting equipment, and therefore need to be considered in the construction of hospitals in the shaft of the reservation. In addition, the box-type logistics conveying system horizontal conveying equipment layout has two forms of floor mounting and lifting, equipment deployment needs to occupy a certain amount of space.
Automatic guided vehicle (AGV) conveying system. Automatic Guided Vehicle (AGV) conveying system, also known as trackless flexible transmission system, in the hospital field called "medical logistics robot", "medical flow robot" "AGV logistics robot", is a kind of Through the automatic guided vehicle in the floor and different floors shuttle back and forth, carrying loads of cars to realize the hospital materials from the starting station to the end station of the logistics conveyor system.
Automatic guided vehicle transportation system generally consists of actuators, traveling devices, sensing elements, remote control networks and control systems. Automatic guided vehicle transport system is under the control of computers and wireless local area network unmanned automatic guided transport vehicle, guided by magnetic, laser and other guiding devices to run according to the programmed path and stop to the designated location, to complete a series of items to move loads, handling and other operational functions, so as to achieve the hospital goods transmission.
Automatic guided vehicle system first appeared in the 1950s, the 1970s began in Europe, America, Japan and other developed countries to promote the application. The automatic guided vehicle system was initially used in the industrial field, and then entered the hospital field, used to solve the problem of bulk material transportation in the hospital.
The biggest difference with the rail trolley is that the system adopts trackless horizontal transmission, which is not constrained by various piping systems on the floor. In terms of load capacity AGV logistics robot has its advantages, its load weight up to 80kg, can meet 85% of the medical goods transportation needs.
The AGV robot device is able to travel in accordance with the prescribed guidance path (electromagnetic track, etc.), with safety protection and a variety of shifting functions, but due to the terrain and environmental constraints, it is more difficult to realize the transmission of materials throughout the hospital.
Conveyor systems have their own advantages, to solve the problem of hospital material transportation is not the same. Hospitals should be based on their own actual situation, analyze the delivery of materials to determine the specific use of what kind of transmission or the use of a variety of conveyor systems to meet their actual needs.
