Description
Technical Field
The invention relates to the technical field of logistics equipment, in particular to the technical field of electromechanical automatic logistics equipment, and specifically relates to a blocking mechanism.
Background
The logistics storage industry has been developed vigorously in China in recent years, and due to the continuous progress of technology and capability of the manufacturing industry and the further increase of requirements at home and abroad, higher requirements are put forward on logistics storage and the distribution capability of local materials or parts. The traditional manpower-intensive logistics mode cannot meet the modern logistics requirements of various types, large differences in shapes and weights and increasing efficiency requirements at present.
In order to meet the demand of modern logistics, a lot of automatic warehouse and handling devices, such as an automatic stereoscopic warehouse, a stacker, a gripping robot, a conveying device, an AGV (automated guided Vehicle), and the like, have been used in the industry. However, in some special logistics and parts logistics handling fields, the prior art still has certain limitations.
For example, the chinese utility model patent "an E-frame automatic wiring system" (patent No. ZL201420109121.5) discloses the following: an AGV simultaneously pulls a plurality of E-type vehicles to accurately stop, can push a material rack on an E-type frame for placing various articles such as goods or material boxes to be carried out to a powerless side roller line aligned with the frame, or can pull the material rack on the powerless side roller line aligned with the frame back to the frame, and then can pull an on-line system to other specified stations through the AGV and the like to automatically go on and off the line of the material rack; the system improves the utilization rate and the working efficiency of the operation space, and reduces the cost of installing power and control equipment at the operation station. The unpowered line side roller line mentioned in the patent is mostly fixed on the ground through four ground feet, and the unpowered line side roller line is inclined inwards by adjusting the height difference of the front ground foot and the rear ground foot, so that a material rack pushed onto the unpowered line side roller line cannot slide off from a pushing-in end; but at the artifical in-process of getting the material, especially people stand and get the material on the work or material rest, hardly guarantee that the work or material rest can not follow the end landing of pushing in, have the potential safety hazard.
At present, a one-way blocking device similar to that shown in fig. 1 is arranged on a power-free labor-saving line edge mechanism similar to a power-free roller line, the one-way blocking device generally comprises a turning plate 1, a turning plate fixing seat 2, a turning plate rotating shaft 3 and a torsion spring 4, the turning plate rotating shaft 3 is transversely arranged on the turning plate fixing seat 2, the turning plate 1 is vertically arranged and can be rotatably arranged on the turning plate rotating shaft 3 backwards (along the direction of an acting force F shown by an arrow in the figure), the turning plate 1 cannot rotate forwards, and the torsion spring 4 is sleeved on the turning plate rotating shaft 3 and respectively abuts against the turning plate 1 and the turning plate rotating shaft 3 to tend to enable the turning plate. When the automatic turnover mechanism is used, the turnover plate fixing seat 2 is fixed at the pushing-in end of the unpowered labor-saving line edge mechanism, the front of the turnover plate fixing seat faces outwards, when the material rack is pushed into the unpowered labor-saving line edge mechanism from the pushing-in end, the turnover plate 1 is pushed backwards along the direction of an acting force F shown by an arrow in the figure, the turnover plate 1 rotates backwards until the material rack is pushed into the unpowered labor-saving line edge mechanism, and the turnover plate 1 rotates forwards under the action of the torsion spring 4 until the turnover plate returns to the vertical position.
However, the one-way blocking device can only push the material rack into the material rack from the pushing end but cannot pull the material rack out of the pushing end, and the material rack can only be pulled out of other ports because the one-way blocking device blocks the material rack from being pulled out of the pushing end, so that the use is inconvenient; and the device must be fixed on a powerless labor-saving line edge mechanism, and the height and the position cannot be adjusted.
Therefore, a blocking mechanism is needed to be provided, which is installed at the pushing end of the unpowered labor-saving linear edge mechanism, can push the material rack in from the pushing end and can also pull out from the pushing end, and is convenient to use; preferably, the height and position can also be adjusted to accommodate a variety of situations.
