Description

Coaxial Double Layer Linear Circulation Lifting Cross Belt Sorter

technical field

The invention relates to the technical field of logistics, in particular to a coaxial double-layer linear circulating lifting cross-belt sorter.

Background technique

The cross-belt sorting system is connected by a main drive belt conveyor and a trolley carrying a small belt conveyor (referred to as sorting trolley). When the sorting trolley moves to the specified sorting position, it rotates. The small belt conveyor of the sorting trolley sorts and sends the items placed on the sorting trolley. Because the main drive belt conveyor and the belt conveyor of the sorting trolley are crossed, it is called a cross-belt cross-belt sorter.

The working principle of the coaxial double-layer linear circulating lifting cross-belt sorter is as follows: first, the sorting trolley 2 is driven to move by the linear drive motor, because the central axis of the first arc-shaped groove 304 is in line with the first The central axes of the two arc-shaped grooves 305 are coincident, the front end of the first horizontal slide rail 5 extends into the box 301 and the front end surface of the first horizontal slide rail 5 and the central axis of the first arc-shaped groove 304 The vertical distance is equal to the distance between the central axis of the first roller 204 and the central axis of the third roller 206, the first horizontal rail 5 is located inside the first support plate 302, the third horizontal rail 7 The front end extends into the box body 301 and the vertical distance between the front end surface of the third horizontal slide rail 7 and the central axis of the first circular arc groove 304 is equal to the central axis of the first roller 204 and the central axis of the third roller 206 The distance between the third horizontal slide rail 7 is located on the inner side of the first support plate 302; the front end of the second horizontal slide rail 6 extends into the box 301 and the front end surface of the second horizontal slide rail 6 The vertical distance between the central axes of the arc-shaped grooves 305 is equal to the distance between the central axis of the second roller 208 and the central axis of the fourth roller 210 . Inside, the front end of the fourth horizontal slide rail 8 protrudes into the box 301 and the vertical distance between the front end surface of the fourth horizontal slide rail 8 and the central axis of the second arc-shaped groove 305 is equal to that of the second roller 208 . The distance between the central axis and the central axis of the fourth roller 210, the fourth horizontal slide rail 8 is located on the inner side of the second support plate 303; In the process of moving just above the central axis of the shaped groove 304, the third roller 206 and the fourth roller 210 at the front end of the sorting trolley 2 are disengaged from the first horizontal slide rail 5 and the second horizontal slide rail 6 at the same time. The two adjacent sorting trolleys 2 are connected by a first connecting plate 211, a second connecting plate 212, a first synchronous belt 213, and a second synchronous belt 214. The first synchronous belt 213 and the second synchronous belt 214 move. The function is that as long as one of the sorting trolleys 2 rotates, the other sorting trolleys 2 will also rotate synchronously, that is, as long as one of the sorting trolleys 2 is in a horizontal state, the other sorting trolleys 2 will also be in a horizontal state. The sorting trolley 2 on the horizontal slide rail is in a horizontal state. At this time, even if the sorting trolley 2 is only supported by the third roller 206 and the fourth roller 210 at the rear end of the sorting trolley 2, because the first synchronous belt 213 and the second The function of the two synchronous belts 214 and the functions of the first connecting plate 211 and the second connecting plate 212 will also make all the sorting trolleys 2 in a horizontal state, which can ensure that the sorting trolleys 2 will not turn over during the moving process.
