Description

Technical Field

[0001] The invention relates to the technical field of lifting and conveying equipment, and in particular to an electric end stop mechanism. Background Art

[0002] During the process of painting the car body in white, the car body in white needs to be transported to the corresponding position by being installed on the transfer roller bed, and then the transfer roller bed and the car body in white need to be raised or lowered to a corresponding height by the elevator and then docked with the fixed roller bed fixed on the platform at different heights to realize the lifting and transfer of the car body in white to the corresponding platform for processing. During the lifting process, in order to prevent the car body in white from sliding out of the roller bed, a corresponding end stop mechanism is generally set at the end side of the roller bed for protection.

[0003] However, the existing end stop mechanism completely relies on the realization of control, resulting in the end stop mechanism of the transfer roller bed always colliding with the end stop mechanism of the fixed roller bed arranged on the different height platforms on the end side during the lifting process, regardless of whether it carries objects or whether it needs to stop. This not only causes loud noise and environmental pollution, but also easily damages the end stop mechanism. Summary of the invention

[0004] The purpose of the present invention is to provide an electric end stop mechanism to address the technical defects in the prior art.

[0005] The technical solution adopted to achieve the purpose of the present invention is:

[0006] An electric end stop mechanism comprises a rotatable lifting side blocking plate arranged at both ends of a lifting roller bed and a rotatable fixed side blocking plate arranged at the corresponding side ends of a fixed roller bed, fixed side paddle plates arranged at the side ends of the fixed roller bed corresponding to the lifting side blocking plate and the fixed side blocking plate respectively, and lifting side paddle plates installed at both ends of the lifting roller bed, the fixed side blocking plate and the fixed side paddle plates are kept in a vertical state under the action of gravity to prevent the workpiece from rushing out from the sides of the lifting roller bed and the fixed roller bed; a lifting side blocking plate and a lifting side paddle plate are respectively installed at both ends of the lifting roller bed through two symmetrical moving frames driven by a motor and capable of moving synchronously; when the elevator stops at a certain layer to stop and hand over the workpiece, the moving frame extends outward synchronously, and the lifting side blocking plate and the fixed side blocking plate are paddled by the fixed side paddle plate and the lifting side paddle plate, so that the lifting side blocking plate and the fixed side blocking plate are opened to realize the handover of the workpiece.

[0007] Among them, two symmetrically arranged moving frames are respectively connected to connecting rods driven by motors to achieve synchronous telescopic movement.

[0008] Wherein, the movable frame is moved by rollers.

[0009] Wherein, the fixed side paddle plate and the lifting side paddle plate are arranged horizontally.

[0010] Compared with the traditional end shifter mechanism that completely relies on gravity, the present invention avoids the problem of frequent collision of the end shifter when passing through multiple layers at high speed, reduces noise, and is reliable. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0019] like Figure 1-7 As shown, the electric end stop mechanism of the present invention comprises a rotatable lifting side stop plate 12 arranged at both ends of the lifting roller bed 10 and a rotatable fixed side stop plate 6 arranged at the corresponding side end of the fixed roller bed 7, a fixed side paddle plate 11 arranged at the side end of the fixed roller bed corresponding to the lifting side stop plate and the fixed side stop plate respectively, and a lifting side paddle plate 5 installed at both ends of the lifting roller bed, wherein the fixed side stop plate and the fixed side paddle plate are kept in a vertical state under the action of gravity to prevent the workpiece from rushing out from the side of the lifting roller bed and the fixed roller bed; a lifting side stop plate and a lifting side paddle plate are respectively installed at both ends of the lifting roller bed through two symmetrical moving frames 4 driven by a motor 1 and capable of moving synchronously; when the elevator stops at a certain layer to stop and hand over the workpiece, the moving frame extends outward synchronously, and the lifting side stop plate and the fixed side stop plate are paddled by the fixed side paddle plate and the lifting side paddle plate, so that the lifting side stop plate and the fixed side stop plate are opened to realize the handover of the workpiece.

[0020] The two symmetrically arranged moving frames are respectively connected to the connecting rod 3 driven by the motor 1 to achieve synchronous telescopic movement. The motor 1 can be connected to the connecting rod through the crank mechanism 2. Of course, other methods can also be used to drive the two connecting rods to telescope synchronously, without limitation.

[0021] Among them, the fixed side paddle plate and the lifting side paddle plate are arranged horizontally. Specifically, the lifting side paddle plate is installed on a vertical plate, the vertical plate is installed on the upper end of the mobile frame, the fixed side paddle plate is installed on the paddle plate frame, and the paddle plate frame is fixed on the fixed platform 8 of the fixed roller bed 7.

[0022] The lifting roller bed 10 is installed on the lifting frame, and the fixed side blocking plate is used to prevent the workpiece from rushing out of the fixed roller bed 7 to the elevator hole when the lifting frame is not parked at the layer.

[0023] Among them, the principle of the fixed side blocking plate is: when the lifting frame is not docked at that layer, the blocking plate on the fixed side is kept in a vertical state by the action of gravity to prevent the workpiece from rushing out from the fixed side due to accidental operation; when the elevator is docked at that layer and needs to be handed over, the motor drives the crank to drive the connecting rod to extend, and the connecting rod drives the paddle to extend to open the blocking plate on the fixed side. At this time, the workpiece can be handed over. After the handover is completed, the elevator goes to other layers. At this time, the blocking plate on this layer is kept in a vertical state by the action of gravity and continues to play a protective role.

[0024] Wherein, the function of the lifting frame blocking plate is to provide end blocking protection for the workpiece on the lifting roller bed during the lifting process of the elevator.

[0025] The principle of the lifting frame blocking plate is that during the lifting process of the lifting frame, the blocking plate is affected by gravity and remains in a vertical state to prevent the workpiece from rushing out of the lifting frame. When the elevator stops at a certain floor and needs to be handed over, the motor drives the crank to drive the connecting rod to extend, and the connecting rod drives the blocking plate to extend, and the paddle on the fixed side opens the blocking plate on the lifting frame, and the workpiece can be handed over. After the handover is completed, the elevator goes to other floors. At this time, during the lifting process, the blocking plate is affected by gravity and remains in a vertical state, continuing to play a protective role.

[0026] Among them, the mobile frame 4 is moved by the roller 12, and under the action of the connecting rod, the motor and the crank mechanism, it realizes synchronous telescopic movement, thereby controlling the synchronous movement of the blocking plates and the paddle plates at both ends, and cooperating with the paddle plates and the blocking plates at the upper ends of the corresponding fixed roller beds, or not cooperating. When cooperating, the blocking plates are contacted and opened, or when separated, the corresponding blocking plates are affected by gravity to maintain a vertical state, thereby closing and preventing the workpiece from rushing out of the roller bed.

[0027] The motor drive part of the present invention that is not described in detail is the prior art. For details, please refer to the contents disclosed in Patent 2018221021904.

[0028] Compared with the traditional end shifting mechanism that completely relies on gravity, the electric end shifting mechanism of the present invention avoids the problem of frequent collision of the end shifting mechanism when passing through multiple layers at high speed, reduces noise, and is reliable and safe.

[0029] The above is only a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
