Automatic reset blocking device and conveying system

Abstract

The invention discloses an automatic reset blocking device. The device comprises a blocking assembly and a jacking assembly, the blocking assembly comprises a check block body and a movable shaft which are connected with each other, the check block body comprises an upper check block and a lower check block, the movable shaft is used for being fixedly connected with a conveying roller way, and the weight of the upper check block is smaller than that of the lower check block; the jacking assembly comprises a jacking rod, a jacking block and a driving device, the upper end of the jacking rod is connected with the jacking block, the lower end of the jacking rod is connected with the driving device, and the jacking rod and the jacking block can be driven by the driving device to reciprocate up and down; the jacking block is located below the lower check block, and when the jacking block acts on the lower check block, and the check block body can move on the movable shaft along with vertical movement of the jacking block, so that the upper check block is higher than or lower than the conveying surface of the conveying roller way. The invention further discloses a conveying system. According to the automatic reset blocking device and the conveying system, automatic reset is achieved through gravity, the structure is simple, workpieces can be effectively prevented from leaving the conveying roller way by mistake, and the probability of workpiece scrapping and equipment damage caused by mistake can be reduced.

Description

technical field [0001] The invention relates to the technical field of roller conveying, in particular to an automatic reset blocking device and a conveying system. Background technique [0002] Roller conveyors are used in all aspects of production and life, and are often used to transport various goods. Due to the advantages of simple structure and strong reliability of roller conveyors, different roller conveyors or combinations with other equipment are suitable for applications that require heavy loads. It is also suitable for the occasion of conveying large workpieces in the case of shock load. [0003] Among them, when the roller table is set in parallel to transport large workpieces, in order to transport the workpieces conveyed on the roller table to other stations or processes, it is often used to set up a transfer device such as a translation trolley at the end of the roller table as a transfer device. At present, when the workpiece is transported to the end, the ...

Problems solved by technology

[0004] However, there are some defects in completely relying on the photoelectric switch. Since there is no effective blocking structure at the exit of the roller table, if the photoelectric signal is delayed, the workpiece will continue to move forward beyond the normal forming range and protrude from the roller table, and the subsequent translation trolley will move past here. It will collide with the workpiece, which will easily cause the workpiece to be scrapped and the translation trolley to be damaged.

If the electrical control abnormality, hardware damage or short circuit cause abnormal events for a long time, the workpiece will keep falling down under the conveying of the roller table, which will also cause scrapping and damage
