Description

Be used for full detection mechanism of transfer chain end material

Technical Field

The utility model relates to a be used for terminal material of transfer chain to fill detection mechanism belongs to the full detection mechanism technical field of conveyer belt material.

Background

When the conveying line is used for feeding and discharging materials on a machine tool, the materials are discharged and taken by manpower or a manipulator, and the conveying line rotates in a wheel way. On the fixed-pitch feeding conveying line, when the workpieces reach the material taking position, all the workpieces are taken away by the manipulator and can move to the next station, and at the moment, a workpiece detection device needs to be additionally arranged at the tail end to prevent the workpieces from flowing to the next station and influencing the normal operation of equipment. When a plurality of workpieces are arranged on a bottom plate, the manipulator needs to take all the workpieces away so as to continue to operate.

In order to prevent the workpieces from flowing to the next station and affecting the normal operation of the equipment, a plurality of travel switches are required to be added at the tail end of the conveying line to detect whether each tool has the workpiece, so that a plurality of travel switches have to be added, but the addition of a plurality of travel switches to detect the workpieces has two disadvantages: firstly, a plurality of travel switches are installed, so that the cost of the conveying line is high; and secondly, a plurality of travel switches can simultaneously position a plurality of workpieces, and compared with the situation that only one workpiece is positioned by one travel switch, the positioning is more difficult.

Detailed Description

In order to make the technical means, the creation features, the achievement purposes and the functions of the present invention easy to understand and understand, the present invention is further explained by combining the following specific drawings.

As shown in fig. 1-3, a full material detection mechanism for a conveying line end comprises a fixed pitch conveyor 1, a tooling bottom plate 2 and a mechanical gripper 5, wherein a plurality of tooling bottom plates 2 are transported on the fixed pitch conveyor 1 in a flowing manner, each tooling bottom plate 2 is provided with a plurality of stations, each station is loaded with a workpiece 3, the mechanical gripper 5 is arranged above a material taking position at the end of the fixed pitch conveyor 1, and the full material detection mechanism further comprises an end detection mechanism 4;

the tail end detection mechanism 4 is arranged at the tail end of the fixed pitch conveyor 1 and comprises a fixing plate 41, a stop plate 42, a travel switch 43, a spring 44, linear bearings 45, guide shafts 46 and fixing supports 47, wherein the fixing supports 47 are arranged on two sides of the tail end of the fixed pitch conveyor 1, the fixing plate 41 stretches across the upper portion of the fixed pitch conveyor 1 and is fixed between the fixing supports 47 on the two sides, the fixing plate 41 is fixedly provided with two parallel guide shafts 46, each guide shaft 46 is sleeved with a linear bearing 45, the stop plate 42 is fixed on the two linear bearings 45, the spring 44 is sleeved on the guide shaft 46 between the linear bearing 45 and the fixing plate 41, and the travel switch 43 is arranged between the stop plate 42 and the fixing plate 41.

The guide shaft 46 is welded and fixed to the fixed plate 41.

The working principle is as follows:

normally, a plurality of workpieces 3 are carried on the tooling bottom plate 2 on the fixed-pitch conveyor 1, and when the tooling bottom plate 2 transports the workpieces 3 to the tail end of the fixed-pitch conveyor 1, the mechanical gripper 5 can timely grab all the workpieces 5 at the station.

The mechanical gripper 5 may fail to grab the workpiece 3 in a wrong way, and the workpiece 3 is left on the tool bottom plate 2 and continues to move forward; at the moment, the tail end detection mechanism 4 plays a role, two parallel guide shafts 46 are fixedly welded on the fixing plate 41, each guide shaft 46 is sleeved with a linear bearing 45, the stop plate 42 is fixed on the two linear bearings 45, a spring 44 is sleeved on the guide shaft 46 between the linear bearing 45 and the fixing plate 41, the workpiece 3 can touch the stop plate 42 of the tail end detection mechanism 4 when continuing to advance, the stop plate 42 receives forward thrust from the workpiece 3 to trigger a travel switch 43 between the stop plate 42 and the fixing plate 41, and after the travel switch 43 is triggered, the fixed pitch conveyor 1 gives an alarm and stops running in time to prevent the workpiece 3 from continuing to advance.
