what is carton flow rack?

Carton flow rack, also known as sliding racking system, uses rollers aluminum alloy, sheet metal and other fluent strips to store goods from one side of the channel and pick up goods from the other side of the channel to achieve first-in-first-out, convenient storage, and multiple pick-ups for one replenishment. The racks are adjustable and designed from an ergonomic point of view in order to obtain efficient handling for the workers. Storing in carton flow systems has large economic advantages due to the fact that cartons are stored with a high packing density, releasing floor space compared with traditional storage methods, while also reducing travel distances and times between stock shelves and picking face.

Installation of carton flow rack

According to the different load-bearing parts of the carton flow rack, they can be divided into two types of crossbeam load-bearing and side-plate load-bearing: (1) crossbeam load-bearing i.e. front and rear crossbeams are directly installed on the upright, and support beams are installed in the middle upright; (2) side-plate load-bearing i.e. side plates are locked on the columns, and front and rear beams and support beams are installed on the side plates. The side plate load-bearing carton flow rack also needs to be installed with crossbeams to increase the stability of the rack. The tilting degree of flow bars depends on the size of the container, the weight level and the movement speed of the carton, usually the tilting degree is between 5% and 9%, the load capacity of flow bars is usually 5-6kg/roller, two flow bars are sufficient for normal load. Usually it is not the strength but the stiffness of the bars that affect the load capacity and recommends installing a support beam every 600mm below the bars.

The Main Production Process Of Carton Flow Rack

Punching Process

Punches run the length of the hanging plate at standard intervals where the cross beams are connected, most of them are 50mm or 75mm pitch.

Rolling Process

Steel coil through the rolling equipment to form the upright and beam, beam usually have P beam and interlock beam, upright usually have diamond hole and teardrop hole.

Welding Process

Through welding, the hanging plate and beam; upright and footplate are closely connected together, which effectively strengthens the stability of the rack structure.

Spraying And Baking Process

Polish the product after welding, then use electrostatic powder spraying technology on the surface, and finally use the high-temperature baking process to ensure a smooth surface.

Packaging Process

Finally came to the last step. After the production of the product is completed, we usually package the exported goods to avoid long-distance transportation damage and seawater erosion during shipping.

Carton flow racks are combined by upright frame, sliding layer, the sliding layer has a certain inclination, and the goods are stored in standard crates and cartons. When feeding, the crates slide in through the sliding layer, and when the goods in the front crates are finished, the empty crates are taken out and the back crates are automatically slid to the pick-up point, which is the best FIFO storage method. The flow bars of the carton flow rack are directly connected to the front and rear crossbeams and the middle support beam, and the crossbeam is directly hung on the upright. The inclination of the flow bar installation depends on the size and weight of the crates and the depth of the carton flow rack, which is usually taken as 5%~9%. The load capacity of fluent strip roller is 6kg/only, when the cargo is heavy, 3-4 flow bars can be installed in one slideway. Usually a support beam is installed every 0.6m in the depth direction to increase the rigidity of flow bar. When the slideway is long, the slideway can be separated by dividers. At the pick-up end, brake pads should be installed to slow down the cargo and reduce the impact.

1, High density storage, space saving, storage utilization rate increased by more than 60% compared with ordinary racks.

2, Improve logistics efficiency, save time, access efficiency is 10 times of ordinary racks.

3, Short payback period, about 2 years, the economic benefits are significant.

4, Saving forklift usage, low cost of use.

5, Easy to operate, no regular maintenance, reliable and durable.

6, Environmental protection and energy saving, no pollution and no need for any energy operation.

7, Safety, reduce or completely eliminate the damage of items, especially suitable for the storage of fragile items.

Stability is not easy to control, more electromechanical devices, higher construction cost, difficult to maintain.

1, the stability of the carton flow rack. Rack stability has been one of the key issues in the design of the rack structure, because there are many uncertainties in the design, construction and use of the rack structure, so the stability of the rack in the purchase is essential.

2, Racks in the purchase, see if there is no deformation or uneven phenomenon. Such racks are not strictly inspected at the time of production. Of course, it is also poor quality racks. The material used for the racks must meet the national standards, if it does not meet the national standards, it is also not allowed to buy.

3, Advanced planning of warehouse. Choose carton flow racking system must choose to fit their own warehouse characteristics, so before buying must be planning first, or let professional and technical personnel for customized, so that the utilization of the warehouse will be greatly increased, but also let the possibility of future problems may arise to a minimum.

4, process issues. Choose whether the material of the rack meets the requirements you need, in line with your standards; carton flow rack parts should be degreased, rust removal, pretreatment, electrostatic spraying, high temperature curing and many other links. The quality of the powder is also superior and poor, generally each rack company has a standard color, spraying standard color is generally low cost, if you use a special color, changing the powder will increase the work period, waste powder, so the cost will be relatively high.

5, whether the parts are complete. When you buy the carton flow rack, but also look at the carton flow rack on the parts, screws, etc. if there is no matching complete, then be sure to talk to the carton flow rack supplier, this can avoid some losses.

1, from the rack surface maintenance. racks in the warehouse, especially in small and medium-sized warehouses, uncertainty is predominant, prone to a lot of interference and surface problems. Such as moisture, rust, dust, etc… If the racks appear peeling and rust problems, should be time to deal with these places, the protective paint spraying treatment, these parts of the treatment evenly, to prevent the emergence of secondary problems. At the same time, the warehouse to do timely and targeted ventilation and other processing, to maintain a certain amount of airflow, in order to prevent excessive moisture or other situations occur. At the same time, falling on the rack dust, etc. is also must-do maintenance, dust is not only easy to contaminate the product, and the use of racks will also have a negative impact, such as the rack on the sign, or the pollution of fixed parts and management personnel operations, etc. cause trouble, in not serious when it should be cleaned up in a timely and effective manner.

2, Maintenance from the physical protection of the carton flow rack. This maintenance is mainly manifested in the racks in a reasonable load-bearing operation, to avoid unnecessary rack safety problems occur. In particular, storage racks, each type has its own design standards, load-bearing range is limited. In the actual use should follow this requirement, try not to exceed the standard, to avoid the deformation of the racks and other safety problems of their own. To follow the principle of racks bottom heavy top light, that is, the bottom layer put heavy things, the upper layer put light things. In addition, the treatment of racks, certain occasions to take the necessary anti-creation measures to prevent the occurrence of accidental damage to the physical. Such as anti-collision network, anti-collision bar and other settings.

3, from the daily details of the carton flow rack maintenance. Details of the maintenance often play a key effect. racks this thing often surface can not see why the problem, focus on the details of the hitch, can avoid many problems. Daily operations should be strictly in accordance with the specifications of the designated good storage management engaged in, so that the system specification, operation specification, the details of the specification. Avoid the management problems of light-heartedness and fluke. Usually, the warehouse should be implemented to each detail processing range of hygiene and the regular placement of goods, etc., from the usual, as far as possible to do consistently.

Carton flow racking system are highly efficient in storage and suitable for short-term storage and picking of large quantities of goods. It can be equipped with electronic tags to achieve easy management of goods. Commonly used sliding containers include crates, parts boxes and cartons, which are suitable for short-term storage and picking of large quantities of goods. Carton flow rack is widely used in manufacturing, commerce, distribution centers, assembly plants and warehouses with high shipment frequency, and is suitable for production lines and distribution centers.

Stocking goods from one side of the aisle and picking up goods from the other side of the aisle realizes FIFO, convenient storage, as well as multiple pickups for one replenishment, which is advantageous for short-term storage and picking of some large quantities of goods. Carton flow racking system is also beneficial for goods with strict rack life requirements because it can guarantee FIFO, so it is widely used in manufacturing, commerce, distribution centers, assembly plants and warehouses with high shipment frequency.

1, the load-bearing of the two racking types is different, the load of carton flow rack is normally within 500kg, while the single pallet load of gravity flow rack is generally around 1000kg.

2, the main structure of the two racks is different, carton flow racking systems are used in the framework of medium duty racks, while gravity flow racks are used in the framework of heavy duty racks.

3, the internal structure of the two differences, gravity racking system is equipped with rollers, in addition to the guide plate, damping roller and other devices, while the carton flow rack and gravity flow racks compared to the simpler, the basic configuration is only flow bars.

4、The cost of gravity flow rack is much more expensive than carton flow rack.

In fact, from the name of the two racks, we can see the main difference between the two racks, that is, the two different weight-bearing capacities. Because of the different materials chosen in the production, gravity flow racks are better than carton flow racks in terms of load-bearing capacity. The material used for carton flow rack is flow bars, while gravity flow rack uses rollers with stronger load-bearing capacity, and some damping devices are usually installed to prevent the goods from sliding too fast. Although the load-bearing capacity of rollers is better, but it is also more expensive to manufacture, so companies should choose according to their actual needs.
