As shown in Figures 1-5, it includes a bracket 1, a screw 2 mounted on the bracket 1, and a servo motor 7 that drives the screw 2 to rotate. 2. A push plate mechanism 3 that moves along the long axis. The push plate mechanism 3 includes a side plate 6 for clamping the product. The screw mandrel 2 is installed on the support 1 through a bearing, and is driven by the servo motor 7 to rotate by itself. The two push plate mechanisms 3 move in opposite directions on the screw mandrel 2, so that the push plate mechanisms 3 clamp or loosen the product under the power transmission of the servo motor 7 and the screw mandrel 2.

The screw mandrel 2 can be a whole rod, and the two sides are respectively provided with threads with opposite helical directions, so that the push plate mechanisms 3 on both sides can approach or move away from each other, and the servo motor 7 drives the screw mandrel 2 to rotate by itself through the synchronous wheel.

The screw rod 2 can also be two independent screw rods. When the two screw rods are installed on the bracket 1, the centerlines of the two screw rods coincide, the helical directions of the two screw rods are opposite, and the adjacent ends of the two screw rods Install the shaft coupling, the shaft coupling and the servo motor 7 are equipped with synchronous wheels, and the servo motor 7 drives the two screw rods to rotate by itself through the synchronous wheel. When the push plate mechanism 3 touches the product, the stop signal of the servo motor 7 is triggered to make the servo Motor 7 stops automatically.

On the one hand, the side plate 6 is used for clamping products, and on the other hand, it can also shape the scattered products. The torque control mode of the servo motor 7 can automatically stop without any additional signal collection device, and the side plate 6 will touch the product. Trigger the stop signal of the servo motor 7, thereby realizing the function of automatically identifying the product size.

As shown in Figure 5, the push plate mechanism 3 also includes a support frame 31, a short-stroke cylinder 12 for controlling the movement of the side plate 6, the short-stroke cylinder 12 is installed on the support frame 31, and the outside of the side plate 6 is installed on the short-stroke cylinder On the piston rod of 12, the short-stroke cylinder 12 controls the side plate 6 to clamp or loosen the product. When retrieving, the short-stroke cylinder 12 starts to work after the servo motor 7 stops, and controls the side plate 6 to clamp the product.

A guide rail 8 parallel to the screw mandrel 2 is installed on the support 1, and the push plate mechanism 3 is installed on the guide rail 8 and slides freely along the guide rail 8. Both sides, on the one hand, play the role of hanging the push plate mechanism 3, on the other hand, make the push plate mechanism 3 slide along the linear guide rail 8, and then clamp or loosen the product.

A connecting plate 14 is installed between the support 1 and the guide rail 8. In the present embodiment, the support 1 is an aluminum profile. If the guide rail 8 is directly installed on the aluminum profile, it cannot reach the required parallelism for the installation of the guide rail 8. Therefore, in the support 1 A connecting plate with high flatness is arranged between the guide rail 8 to meet the required parallelism of the guide rail 8 .

A base plate 9 is hinged on the base of the side plate 6 , and the outside of the side plate 6 is equipped with a standard cylinder 4 for driving the base plate 9 to rotate around the base of the side plate 6 . A hinge mechanism 5 is installed on the piston rod of the standard cylinder 4, and the standard cylinder 4 drives the base plate 9 to rotate through the hinge mechanism 5. The hinge mechanism 5 comprises a first hinge plate 51 and a second hinge plate 52, one end of the first hinge plate 51 and the second hinge plate 52 is hinged with the piston rod of the standard cylinder 4, the other end of the first hinge plate 51 is connected with the side plate 6 is hinged to the outside, and the other end of the second hinge plate 52 is hinged to the outside of the bottom plate 9.

The second hinge plate 52 is arc-shaped, which effectively prevents the activity of the second hinge plate 52 from being interfered by the bottom edge of the side plate 6, and also helps to shorten the stroke of the piston rod of the standard cylinder 4.

The working process of the utility model is as follows: Take the stacked corrugated cardboard as an example, as shown in Figure 2, the lifting equipment will transfer the bracket 1 to the top of the product to be clamped, as shown in Figure 3, the direction indicated by the horizontal arrow It is the moving direction of the push plate mechanism 3. The servo motor 7 drives the push plate mechanism 3 to move to the middle through the screw rod 2. When the side plate 6 touches the product, the stop signal of the servo motor 7 is triggered, and the servo motor 7 automatically Stop the machine, and the screw mandrel 2 will not be further rotated. Then, the short-stroke cylinder 12 drives the side plate 6 to further compress the product without damaging the product, so as to avoid the product from falling. The hoisting equipment lifts the bracket 1. The falling cardboard will also fall in an orderly manner through the shaping effect of the base plate 9, as shown in Figure 4, the direction indicated by the curved arrow is the rotation direction of the base plate 9, and during the lifting process of the support 1, the standard cylinder 4 pushes the base plate 9 Folding inward, the products that will continue to fall will directly fall on the bottom plate 9. When the bottom plate 9 is folded to a horizontal state, the hoisting equipment will transfer the bracket 1 to the destination, and the bottom plate 9 will be opened to realize unloading. Go back and repeat the gripping work.
