Now, logistics sliding pallet transportation has been widely used in developed countries, but in the field of logistics in China, this transportation method has not been well popularized. As a trend of logistics development in the future, the grain profession began to explore the grain palletized transportation earlier, and specially issued a notice to promote the grain palletized transportation in the whole profession.
Sliding pallet transportation is a transportation method that the goods are assembled on a standard pallet according to certain requirements to form a transportation unit, which is convenient for loading, unloading, mailing and stacking by using the special accessories of forklift. It can effectively reduce the labor intensity of each link, reduce the ineffective labor such as repeated stacking and handling, improve power, save manpower and time cost. The technical problems of vertical sliding tray applied in standardizing bagged and boxed goods have been experienced, and large domestic commodity circulation enterprises have been improving and trying on a large scale.
For grain transportation, vertical sliding pallet transportation can avoid the damage caused by manual handling, and further improve the standardization and automation level of transportation, storage and other links, improve the whole process operation power and modern logistics construction level. At that time, when carrying out the food pallet transportation, many professional units mainly used wood or plastic cards. Although they had certain advantages, they also had some problems, such as low carrying power, difficult to recover the pallet, high cost and large storage space.
Summing up the development of sliding pallet transportation in logistics field, the author thinks that for some enterprises, it is a good choice to choose vertical plastic sliding pallet for repeated recovery or paper sliding pallet for one-time transportation. The vertical packaging plastic sliding tray, that is, the tray made of HDPE material with thickness of 0.5-2.5mm through special processing, has the advantages of high resistance, acid resistance, low temperature environment, constant brittleness at - 40 ℃ and repeated use for many times. The plastic sliding pallet can be placed on the flat ground to stack goods directly, and the whole pallet can be loaded and unloaded by using the special push-pull forklift. Because of the characteristics of thin thickness, light weight, heavy bearing and easy recovery, the selection of plastic sliding pallet can improve the loading power of transport vehicles and overcome the problem of traditional pallet recovery.
Combined with the process of professional grain logistics at that time, the author combed all aspects of the selection of plastic sliding tray transportation.
Industry: grain products are transported to the elevated warehouse offline - plastic sliding trays are placed (RFID chips have been pasted and data association has been made) - manipulator palletizing - entering the elevated warehouse - leaving the warehouse - stretching film wrapping - direct operation of the pusher and puller, and the IC data of the tray are scanned together - the pusher and puller forklift puts the whole tray of grain products into the carriage (excluding traditional trays, including paper sliding trays) ）On the way.
Commercial aspect: grain product arrival - push-pull forklift to place the whole tray of grain products on the traditional tray (including paper sliding tray) - whole tray scanning code - conventional forklift to move the whole tray of grain products to the warehouse (including traditional tray and paper sliding tray) - whole tray of grain products out of the warehouse - take back the plastic sliding tray.
At present, according to the different stacking method and height of pallets, the dimensions of sliding pallets are 1250mm × 1000mm × 150mm (length × width × height, the same below). The trunk transportation of grain products from industry to commerce is carried by Van trucks, the length of which ranges from 4.2 m to 16.5 M. for example, the dimensions of 9.6 m Van trucks are 9600 mm × 2400 mm × 2600 mm and 16.5 m, and the dimensions of Van trucks are 16500 mm × 2600 mm × 2850 mm.
In order to complete the palletized transportation of grain products with high carrying rate, not only two pallets of grain products can be arranged side by side in the carriage, but also two pallets of grain products can be stacked up and down, that is, four pallets of chemical products can be placed in each section of the carriage. Combined with the current palletizing method of professional grain product pallets and the carriage size of transport vehicles, we found that 24 pieces / pallet and 16.5m van type truck are a combination of * high power, with little change to the existing operation mode.
In addition, because of the special use of plastic sliding pallet, enterprises need to purchase special push-pull forklifts. When purchasing the corresponding sliding pallet, they also need to pay attention to the thickness, weight, tearing degree, double-sided friction coefficient of the pallet. For many enterprises, the push-pull forklift belongs to a new type of forklift, and its lifting height and operation accuracy put forward higher requirements for the driver. It can be said that the driver's operation level also directly affects the loading and unloading power.
