Continuous vertical conveyor for unit goods in logistics warehousing distribution center

1 Scope

China's national standard for continuous vertical conveyors handling unit loads in warehouses and distribution centres, applied together with Amendment 1 of 2021. It specifies the terms and definitions, the types and basic parameters, the technical requirements, the test methods, the inspection rules and the marking, packaging and transport. A continuous vertical conveyor moves cartons and totes between floors on a chain of carriers that never stops, taking a load at the bottom and delivering it at the top without the batching a lift imposes. That distinction is the whole point: a goods lift moves one load at a time and its throughput is limited by the round trip, whereas a continuous conveyor's throughput is limited only by how closely the carriers follow one another. In a distribution centre sorting thousands of parcels an hour across several floors, that difference decides the building's layout. The requirements concentrate on what happens when a load is taken on or released while everything is still moving, which is where these machines jam and where people get hurt.

This document specifies the terms, types, basic parameters, technical requirements, test methods, inspection rules, marks, packaging, transportation and storage for continuous vertical conveyor for unit goods. This Standard applies to the conveyors that convey the unit goods in layers along the vertical direction (hereinafter referred to as "conveyors"). Other continuous vertical conveyors can use this Standard as reference.

3 Terms and definitions

For the purposes of this document, the following terms and definitions apply.

3.1 unit goods A single regular item that can be conveyed or a single conveyed item formed in a container.

3.2 carrying device A device capable of carrying an item and operating with a lift traction part.

3.4 conveying rate The number of pieces conveyed in a unit time.

4 Types and basic parameters

4.1 Types Conveyors are divided into type Z, type C, type E according to the conveying method, as shown in Figure 1.

4.2.1 Conveying speed The conveying speed shall preferably use the values specified in Table 1.

4.2.2 Width of carrying device The width of the carrying device shall preferably be the value specified in Table 2.

6 Test methods

6.1 Visual inspection Visually inspect whether the safety warning signs, entrance and exit protection devices, transmission protection devices, outer protection facilities, chain guides, and the interface between the guide rails meet the requirements.

6.2 Level state testing of carrying device Check whether the connection point between the carrying device and the traction part is in a horizontal state. Use a laser level to measure whether the carrying device and the corresponding link of the connecting chain are the same height.

6.5 Noise measurement When the conveyor is running at rated speed with no load, take 4 points from 1m at the exit and entrance to the direction of the conveyor. See Figure

5.Use gear A reading of the sound level meter to test the noise of each point. During the test, except for impulse sound peaks, according to the noise measurement value of each point, calculate the average sound pressure level noise.

6.6 Testing of coating adhesion The measurement method for paint film adhesion shall comply with the provisions of

8 Marks, packaging, transportation and storage

8.1 Marks Signage shall be fixed at a prominent position on the conveyor. The signage shall comply with the provisions of GB/T 13306, and at least indicate the following contents.
