Description

Conveyor system shelf turning device Technical field

The present invention relates to a delivery system, and more particularly to a transfer device for effecting a transfer of a shelf between a screening line and a feed line.

Background technique

The conveying system is used for long-distance transmission of goods. In the modern warehousing and logistics management system, it is usually applied to the conveying system. The conveying system includes a screening line and a plurality of feeding lines, and the feeding line is connected with the screening line for clamping. The shelf of the cargo needs to travel between the screening line and the feeding line. Since the screening line and the feeding line usually have an angle between them, at the position where the two conveying lines meet, the shelf needs to be tracked. The hooks on the shelves are generally formed by bending the metal strips. The stability of the hooks during the hooking process is relatively poor. During the process of changing the racks, the racking phenomenon may occur due to the shaking of the racks. In the process of transporting goods, some goods are fragile, and the falling of the shelves will bring losses. Therefore, in the actual application process, the speed of the shelf during the traveling process is relatively low, which leads to low working efficiency of the conveying system, and the falling of the shelf during the orbit change also occurs from time to time.

Summary of the invention

The technical problem to be solved by the present invention is to provide a conveyor system shelf turning device, which can effectively reduce the probability of the shelf falling when changing the track between the screening line and the feeding line.

In order to solve the technical problem, the technical solution of the present invention is: a conveyor system shelf turning device, disposed between the screening line and the feeding line, comprising a feeding rod formed on the outlet end side of the feeding line, the feeding rod and The screening line has an angle between the screening lines, and the hanging line of the supply rack hook is attached to the screening line, and the outlet end of the feeding rod extends from the upper side of the hanging portion to the screening line, wherein the screening line is close to the feeding line. The opposite sides of the rod outlet end position are respectively provided with blocking members, and the interval between the two blocking members is smaller than the outer diameter of the shelf hook, and the blocking member corrects the position of the hook by blocking the shelf hook at a high position, the blocking member and the blocking member Between the outlet end of the feeding rod, there is a space where the supply rack hook falls onto the screening line hanging portion, and there is a space between the blocking member and the hanging portion through which the supply rack hook passes, and the position of the limiting member on the screening line is biased toward The downstream side of the position where the exit end of the rod is placed.

The angle between the screening line and the feeding rod is generally that the feeding rod is inclined with respect to the screening line, and the two are not parallel. Moreover, the feeding rod is inclined in the vertical direction, and the shelf is slid on the feeding rod to the screening line by the gravity of the rack and the cargo itself. The limiting member is located on the downstream side of the outlet end of the feeding rod, which is determined by the direction in which the screening line is transported to the shelf. When the shelf enters the screening line from the feeding rod, the shelf needs to undergo a process of changing the track. In addition, the structure of the screening line itself may adversely affect the stability of the shelf hook. During the orbital change process, the spatial position of the shelf may be greatly deviated. By placing two limit members on opposite sides of the screening line, the shelf During the orbital travel process, if the position of the hook on the shelf is large, the touch of the hook through the limit member is corrected, so that the shelf enters the hook of the screening line in a substantially ideal space state, and the shelf is reduced. probability. The limiting member may be a rod-shaped body, generally adopting the following limiting plate, and the two limiting plates are flush with the side facing the outlet end of the feeding rod.

Further, the limiting member is a limiting plate, and the two limiting plates are arranged in parallel at opposite sides of the conveying line. The limiting plate is selected to facilitate the connection of the limiting member, so that the stability of the limiting member is good.

Further, in the conveying direction of the screening line to the shelf, the distance between the outlet end of the feeding rod and the limiting member is between 5-8 mm. This makes it possible to stabilize the hook on the upper part of the hooking part of the screening line after the shelf is fed out of the rod, and the correction effect of the limiting piece on the hook is ensured.

Further, a mounting plate is provided on the feeding rod at the inner side of the outlet end, and the mounting plate is disposed in the direction of the feeding rod and spaced apart from the feeding rod. A sprocket is mounted on the mounting plate for overlapping with the chain in the needle drive mechanism to facilitate setting of the drive mechanism on the feed line.

Further, a coupling block is fixed on the feeding line, and an adjusting rod is screwed into the coupling block, and one end of the adjusting rod abuts against the mounting plate. The adjustment of the position of the mounting plate is achieved by the arrangement of the coupling block and the adjustment lever, so that the mounting plate can be well adapted to the tensioning requirements of the drive chain.

Further, the lower side edge of the mounting plate has a flange extending toward the feeding rod. In addition to increasing the strength of the mounting plate, the folding edge can also achieve the limitation of the shelf hook by folding close contact with the shelf hook, and the sliding friction force on the shelf hook is small, and the shelf can be effectively increased. Position stability on the pole.

Further, a flat head is formed at the outlet end of the feeding rod, the flat head is parallel to the conveying direction of the screening line, the outer end portion of the flat head extends to the limiting member, and the outer end portion of the flat head is the outlet end of the feeding rod. By providing a flat head, the position of the shelf hook on the feeding rod can be perpendicular to the conveying direction of the screening line as much as possible, and the shelf is facilitated to enter the hanging portion of the screening line.

Further, the screening line includes a plurality of knuckles, the truss includes two vertically disposed booms connected together and a horizontally disposed load bearing rod, the load bearing rods constituting the hook portion. The position at which the load-bearing rod is connected to the boom is offset from the side of the load-bearing rod that faces away from the feed-in rod, and overlaps between the flat head and the load-bearing rod in the vertical direction. The positional relationship between the boom and the load-bearing rod enables the flat head to extend as far as possible to the screening line, facilitating the entry of the shelf into the screening line, which can effectively reduce the probability of the shelf falling.

Further, a protruding plate extending toward the flat head is fixed on the mounting plate, and the protruding plate is formed with a bend, and the bending is matched with the angle between the flat head and the feeding rod, and the protruding plate is extended There is a space between the feed rods through which the supply rack hooks pass, and the extension plates are used to limit the shelf hooks that travel on the flat head. When the shelf passes through the feed bar and the flat position, the extension plate can provide a limit for the shelf hook so that the shelf is in a stable position before entering the screening line.

Compared with the prior art, the present invention has the beneficial effects that since the limiting member is disposed on the downstream side of the outlet end of the feeding rod on the screening line, and the position of the limiting member is close to the feeding rod, the shelf is self-contained. When entering the rod and entering the screening line, due to the orientation of the feeding line relative to the screening line, the shelf will inevitably have a certain degree of shaking, but before the shelf hook enters the hanging portion of the screening line, the limiting member will By making the touch correction of the hook, the whole shelf is in a relatively correct position, and the hook can achieve stable attachment with the hook portion. By setting the limiting member in pairs, the hook can be biased regardless of the direction to which the hook is biased, and one of the limiting members can touch the hook. The working stability of the rotating device is good, and the hook can be stably connected to the screening line. On the hook, it can effectively reduce the chance of falling on the shelf.
