Description

Technical Field

[0001] The invention relates to the technical field of plate conveying and processing, and in particular to a plate conveying buffer mechanism. Background Art

[0002] In the field of sheet metal processing technology, conveyor lines are usually used to transport sheets. When sheets are transported from high to low, inclined conveyor lines are required, such as Figure 1 In the horizontal conveyor line 1 and the inclined conveyor line 2 described in the figure, when the plate 3 enters the inclined conveyor line 2 from the horizontal conveyor line 1, when the center of gravity of the horizontal plate 3 exceeds the horizontal conveyor line, it will directly tilt and flip onto the inclined conveyor line 2. When the area of ​​the plate is large and the plate is thin, the strength of the plate itself is large. As one end of the plate gradually exceeds the horizontal conveyor line 1, the plate will bend and deform, which will lead to cracking of the plate. When the plate is transferred from the horizontal conveyor line to the inclined conveyor line, a certain collision will occur during the contact between the plate and the inclined conveyor line, which will also cause damage to the plate. Summary of the invention

[0003] In order to solve the above problems existing in the prior art, the present invention provides a plate conveying buffer mechanism which can provide buffering protection for plate conveying and prevent the plate from being damaged.

[0004] In order to achieve the above object, the present invention adopts the following technical solution: A plate conveying buffer mechanism includes buffer components arranged on both sides of the upper end of an inclined conveyor line, the buffer components include a connecting strip fixedly mounted on a conveyor line bracket, a buffer rod rotatably connected to the upper end of the connecting strip, a first elastic member driving the buffer rod to open is arranged between the buffer rod and the connecting strip, and an angle limiter assembly for limiting the opening angle of the buffer rod is arranged between the buffer rod and the connecting strip. When the plate moves from a horizontal conveyor line to an inclined conveyor line, both sides of the plate are supported by the buffer rod, and as the center of gravity of the plate moves forward, the buffer rod is compressed and the angle is reduced (closer to the connecting strip) until the plate is completely moved to the inclined conveyor line; through the buffering effect of the buffer rod, the plate is stably transferred from the horizontal conveyor line to the inclined conveyor, and the plate is not easy to bend, deform, or crack.

[0005] Preferably, the angle limiting assembly includes an arc-shaped limiting rod, the center of the circle corresponding to the arc-shaped limiting rod coincides with the rotation center of the buffer rod, the upper end of the arc-shaped limiting rod is fixedly connected to the buffer rod, the lower end of the arc-shaped limiting rod passes through the connecting strip, and the first elastic member is configured as a compression spring, which is sleeved on the arc-shaped limiting rod. The arc-shaped limiting rod can limit the opening angle of the buffer rod.

[0006] Preferably, the lower end of the arc-shaped limiting rod extends to form a stud, the stud is provided with a limiting plate, and both ends of the limiting plate are provided with adjusting nuts. Thus, the limiting plate, the adjusting nut and the screw are connected, and the position of the buffer rod can be adjusted according to actual needs.

[0007] Preferably, a flexible buffer block is provided at the upper end of the limit plate. When the plate is separated from the buffer rod, the buffer rod will be reset under the action of the first elastic member, and the flexible buffer block can play a buffering role to prevent rigid collision during the reset process.

[0008] Preferably, a parallel support rod is provided on the upper side of the buffer rod, a plurality of connecting arms are provided between the support rod and the buffer rod, the lower end of the connecting arm is rotatably connected to the buffer rod, the upper end of the connecting arm is rotatably connected to the support rod, and a second elastic member is provided between the connecting bar and the support rod to drive the support rod away from the buffer rod. The support rod can approach and move away from the buffer rod, and when the plate is supported by the support rod, the support rod can stably release the plate to the surface of the inclined conveyor line, and the overall buffering effect is better.

[0009] Preferably, a limit pin is provided on the buffer rod, and the second elastic member is configured as a tension spring, one end of the tension spring is connected to the upper end of the buffer rod, and the other end of the tension spring is connected to the support rod; when the connecting arm is acted upon by the tension spring and contacts the limit pin for limit, the connecting arm and the buffer rod form an acute angle.

[0010] Preferably, a plurality of parallel and coplanar connecting rods are provided between the two support rods, and the connecting rods are mounted on the upper side of the inclined conveyor line. When the width of the plate is small (when the support rods and buffer rods cannot support both sides of the plate), the connecting rods are used to support the plate and buffer the plate from the horizontal conveyor line to the inclined conveyor line.

[0011] Preferably, the two ends of the connecting rod are fixedly connected to the support rod respectively, the outer side of the connecting rod is rotatably provided with a roller, and the two ends of the connecting rod located at the roller are rotatably provided with support wheels, and the diameter of the support wheel is larger than the diameter of the roller. When the connecting rod is close to the surface of the inclined conveyor line, the support wheel acts on the surface of the inclined conveyor line, and the roller maintains a small gap with the surface of the inclined conveyor line. At this time, the plate slides down along the roller to the surface of the inclined conveyor line, and the whole is more stable and smooth.

[0012] Therefore, the present invention has the beneficial effect of providing buffer protection for plate transportation and preventing the plate from being damaged. BRIEF DESCRIPTION OF THE DRAWINGS

The plate is stably stressed during the whole process, and is not easy to bend or break. This type of buffer mechanism is particularly suitable for conveying plates with large area, small thickness and low self-strength.
