Description

Material stop mechanism and roller way type AGV with same

Technical Field

The utility model relates to the technical field of roller bed AGVs, in particular to a material stop mechanism. The utility model also relates to a roller way type AGV comprising the material stop mechanism.

Background

AGV (Automated Guided Vehicle), namely, an automated guided vehicle, is a vehicle equipped with an electromagnetic or optical automated guide device, which can travel along a predetermined guide path and has safety protection and various transfer functions. The roller bed AGV is one of the important mechanisms of the AGV, namely a stop mechanism, and plays a role in preventing materials from sliding out of a roller bed.

Referring to patent CN202022110848, in the prior art, the stop mechanism of the roller table type AGV is typically a lifting pushrod vertically disposed on the material inlet and outlet side of the roller table. The lifting push rod descends when the material needs to pass through, and the lifting push rod ascends when the material needs to be stopped. In the structure, the lifting push rod is directly stressed, the stopped material is easy to deform under the condition of heavier or impacted, and the lifting and the lowering are blocked when the material is deformed, so that the stopping function cannot be realized; and because the vertical direction of push rod sets up, has certain requirement to the height of AGV, need leave the space that is greater than or equal to push rod length in the roll table below, consequently is not applicable to comparatively frivolous AGV.

Disclosure of Invention

In order to solve the technical problems, it is necessary to provide a material stop mechanism which is not easy to damage, occupies a small space in the vertical direction and can be applied to a light and thin AGV.

In order to solve the technical problems, the utility model provides the following technical scheme:

the material stop mechanism comprises a stop piece capable of rotating to switch between a blocking position and a non-blocking position, and a stop push rod which is matched with the stop piece and limits the stop piece to rotate.

When the material stop mechanism is used, the material stop mechanism is arranged in parallel with a roller way of the roller way type AGV and is arranged on one side of a material inlet and outlet roller way. When the material needs to pass through, the stop push rod is separated from the stop piece, the rotation limitation of the stop piece is relieved, the stop piece is rotated and pressed down by the gravity of the material in the process that the material is conveyed by the roller way to pass through the stop mechanism and enter the AGV, the material passes through smoothly, and the stop piece is rotated to return to the blocking position after the material passes through; when the material needs to be stopped after being in place, the stop push rod is pushed in, so that the stop piece is limited in rotation, the stress is still kept at the blocking position, at the moment, the material cannot pass through the stop mechanism, and the stop mechanism plays a role in preventing the material from sliding out of the roller way. Because the part directly stressed is a stop piece rather than a stop push rod, the stop push rod is not easy to damage, and compared with a conventional material stop mechanism, the durability is improved; because the backstop push rod level sets up, occupation to vertical space is less, material backstop mechanism can be used for comparatively frivolous AGV.

Preferably, the rotation center of the stopper is deviated from the gravity center thereof, and the self weight thereof is in the blocking position in a natural state. In this structure, since the center of gravity of the stopper is deviated from the rotation center, the stopper rotates and remains in the blocking position with the center of gravity located below the rotation center by the own weight.

Preferably, the stopper is directly or indirectly connected with a weight. In this structure, the balancing weight further stabilizes the center of gravity of the stopper below the center of rotation.

Preferably, the stop is directly or indirectly connected with a return spring. In this structure, the stopper is rotated by an external force, the return spring is opened, or the stopper is removed by an external force, the return spring is elastically restored, and the stopper returns to the blocking position. The return spring provides elastic potential energy to pull the stop piece back to the blocking position, and meanwhile a certain buffering effect is achieved.

Preferably, a roller is connected to the head of the stopper. In this structure, the material passes through when the backstop piece, through the effect of running roller, make the sliding friction of material and backstop piece become rolling friction, not only avoid damaging the material, still ensure that the material is effective to be carried.

Preferably, the stop push rod is connected with a driving mechanism for driving the stop push rod to reciprocate in a linear motion. In this structure, the stopper push rod does not need to be manually operated.

Preferably, the driving mechanism is an electric push rod, a linear motor or an air cylinder.

Preferably, the material stop mechanism comprises a stop piece mounting seat, a rotatable rotating shaft is horizontally connected to the stop piece mounting seat, and the stop piece and the balancing weight are sleeved on the rotating shaft and rotate along with the rotating shaft.

Preferably, a connecting rod is arranged on the balancing weight, the end of the return spring is connected to the mounting seat of the stop piece, and the other end of the return spring is connected to the connecting rod; and/or a bayonet for horizontally penetrating the stop push rod is arranged on the stop piece; and/or the stop piece mounting seat comprises two brackets arranged at intervals, the rotating shaft is rotatably and horizontally connected between the two brackets, and a push rod through hole for the stop push rod to pass through is formed in the bracket. In this structure, the stress point that the backstop push rod limited the backstop spare is rotatory is located with on the contact point of bayonet socket, between two brackets, owing to the existence of bracket, the arm of force of push rod atress is shorter, be difficult for the deformation.

A roller way type AGV comprises a vehicle body and a roller way arranged on the vehicle body, wherein one end of the vehicle body for feeding and discharging materials is provided with the material stop mechanism.

The track type AGV provided by the utility model comprises the material stop mechanism, so that the track type AGV has all the beneficial technical effects brought by the material stop mechanism, and the material stop mechanism is not repeated herein.
