Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of palletizing devices, and in particular to an intelligent palletizing device and a working method thereof. Background Art
[0002] With the continuous development of industrial automation, traditional manual palletizing operations are gradually being replaced by intelligent equipment in many fields. In the production line, after the products are inspected, qualified and unqualified products need to be classified and stacked. Traditional palletizing systems usually use a single palletizing method, but in the actual production process, the types and quantities of qualified and unqualified products are often different. How to effectively and quickly classify and stack these products has become a technical problem in automated production lines. Summary of the invention
[0003] Purpose of the invention: The purpose of the present invention is to provide an intelligent palletizing device and a working method thereof, by which a plurality of gripping mechanisms work in parallel and the gripping mechanisms are controlled to rotate by a control motor, so that when qualified products are grasped and palletized, even if unqualified products are missing from the palletizing, the device can still accurately grasp and stack the products without the need for the conveyor belt to change its movement mode.
[0004] Technical solution:
[0005] An intelligent palletizing device comprises a product conveyor belt, a first palletizing mechanism for palletizing unqualified products, a second palletizing mechanism for palletizing qualified products, a qualified product conveyor belt, and a PLC control system; the second palletizing mechanism comprises a second moving seat, and a control component for controlling the second moving seat to move between the conveyor belt and the palletizing platform; the lower end of the second moving seat is connected to a first mounting seat through a control motor rotation; a cylinder is arranged on the first mounting seat, the output end of the cylinder is connected to a second mounting seat, and the lower end of the second mounting seat is provided with more than one row of grabbing mechanisms.
[0006] Furthermore, the control assembly includes a lead screw, a servo motor for controlling the rotation of the lead screw, and a guide shaft, and the second movable seat is threadedly connected to the lead screw and slidably connected to the guide shaft.
[0007] Furthermore, the grabbing mechanisms are arranged in a row.
[0008] Furthermore, the grabbing mechanism is a negative pressure adsorption device or a grabbing manipulator.
[0009] Furthermore, the first mounting seat rotates with the grabbing mechanism at the middle position as the center.
[0010] Furthermore, the first stacking mechanism and the second stacking mechanism have the same structure and are respectively arranged at different positions of the conveyor belt.
[0011] The present invention also discloses a working method of an intelligent palletizing device, comprising the following steps:
[0012] S1. After the products are inspected, they are conveyed to the lower end of the first palletizing mechanism via a conveyor belt. The first palletizing mechanism palletizes the unqualified products from the conveyor belt into the unqualified product collection device;
[0013] S2. The products palletized by the first palletizing mechanism are continuously conveyed forward to the lower end of the second palletizing mechanism, and the second palletizing mechanism palletizes the qualified products from the conveyor belt into the qualified product collecting device.
[0014] Furthermore, the grabbing mechanisms are arranged in a row. In step S2, the grabbing mechanisms are arranged along the length direction of the conveyor belt to grab qualified products on the conveyor belt. The conveyor belt first conveys the qualified products at the front end to the bottom of the grabbing mechanism at the front end. The cylinder drives the grabbing mechanism to move downward to grab the qualified products, and then drives the qualified products to move to the qualified product conveyor belt. If the grabbing mechanisms in the middle have grabbed qualified products, a row of qualified products are directly placed on the qualified product conveyor belt; if the middle grabbing mechanisms have not grabbed qualified products, the qualified products are placed on the qualified product conveyor belt in turn along the direction perpendicular to the qualified product conveyor belt, and the qualified products are skipped if there are any qualified products missing in the middle.
[0015] Furthermore, the method for the first palletizing mechanism to palletize defective products is the same as the method for the second palletizing mechanism to palletize qualified products.
[0016] Beneficial effect: By having multiple grabbing mechanisms working in parallel and controlling the grabbing mechanisms to rotate through a control motor, when grabbing and stacking qualified products, even if unqualified products are missing from the stacking, the device can still accurately grab and stack the products without the need for the conveyor belt to change its movement mode.

By having multiple grabbing mechanisms working in parallel and controlling the grabbing mechanisms to rotate through a control motor, when grabbing and palletizing qualified products, even if unqualified products are missing from the palletizing in the middle, the device can accurately grab and stack the products without the need for the conveyor belt to change the movement mode.
[0023] In this embodiment, the control assembly 22 includes a lead screw 221 , a servo motor 222 for controlling the rotation of the lead screw 221 , and a guide shaft 223 . The second movable seat 21 is threadedly connected to the lead screw 221 and is slidably connected to the guide shaft 223 .
[0024] In this embodiment, the grabbing mechanisms 26 are arranged in a row.
[0025] In this embodiment, the grabbing mechanism 26 is a negative pressure adsorption device or a grabbing robot.
[0026] In this embodiment, the first mounting seat 23 rotates with the grabbing mechanism 26 at the middle position as the center.
[0027] In this embodiment, the first palletizing mechanism 1 and the second palletizing mechanism have the same structure and are respectively arranged at different positions of the conveyor belt.
[0028] The present invention also discloses a working method of the intelligent palletizing device, comprising the following steps:
[0029] S1. After the products are inspected, they are conveyed to the lower end of the first palletizing mechanism via a conveyor belt. The first palletizing mechanism palletizes the unqualified products from the conveyor belt into the unqualified product collection device;
[0030] S2. The products palletized by the first palletizing mechanism are continuously conveyed forward to the lower end of the second palletizing mechanism, and the second palletizing mechanism palletizes the qualified products from the conveyor belt into the qualified product collecting device.
