Description

Technical Field

[0001] The invention belongs to the technical field of product feeding, and in particular relates to a turnover device for transferring products. Background Art

[0002] The products produced in a certain workshop are cylindrical in shape. After a batch of products are produced and formed, the process requires that the density of each product be measured. After the measurement, the products whose density does not meet the standard requirements are selected out.

[0003] The density measurement system used in the workshop includes a workbench, a weighing scale fixed on the workbench surface, a volume measuring device, a robot arm, and a shelf. The workbench is fixed with a shell covering the weighing scale, the volume measuring device and the shelf, and the shell is provided with a window door.

[0004] The method for the density measurement system to measure the density of the product is: S1. The worker opens the window door on the front side of the shell, and then places the product to be measured on the shelf, and ensures that the product is placed at the designated position of the shelf to complete the loading of the product; S2. The robot arm grabs the product on the shelf and puts it on the weighing scale, and the weight of the product is weighed by the weighing scale; S3. The robot arm grabs the product on the weighing scale into the volume measuring device, and the volume measuring device measures the volume of the product; S4. Finally, the density of the product is calculated by the density measurement formula.

[0005] Among them, in step S1, it is necessary to manually open the window door and place the product on the shelf inside the shell. After placing the product, the worker needs to manually close the window door, which undoubtedly increases the work intensity of the workers.

[0006] In addition, workers need to adjust the placement of products several times to place the products at the designated positions on the shelves, which undoubtedly increases the positioning time of the products, thereby increasing the loading time of the products and further reducing the loading efficiency of the products.

[0007] Therefore, there is an urgent need for a turnover device that can reduce the workload of workers and greatly improve product loading efficiency. Summary of the invention

The positions of the two positioning pins C30 match the two positioning holes A8 on the tray 6.

[0042] The working process of the present invention is as follows:

[0043] S1, take out a tray 6, and embed a product 32 to be measured in each blind hole 7 on the tray 6;

[0044] S2, the specific operation steps of transporting the tray 6 and the product 32 thereon from the outside of the housing 2 to the shelf device 4 are as follows:

[0045] S21, the worker stands at the rear side of the workbench 1, and places the pallet 6 flat on the two belts 33 of the two belt conveyors 11 of the conveying device 5; then the two belt conveyors 11 are controlled to start at the same time, the belt conveyors 11 drive the belts 33 to move, and the two belts 33 move the pallet 6 placed thereon toward the front buffer bar 14;

[0046] S22, when the tray 6 is blocked by the front buffer bar 14, the tray 6 is just above the lifting plate 17 of the lifting assembly 13;

[0047] S23, the piston rod of the lifting cylinder 16 of the control lifting assembly 13 moves upward, the piston rod drives the lifting plate 17 to move upward, and the two positioning pins A18 on the lifting plate 17 are respectively inserted into the two positioning holes A8 located on the bottom surface of the tray 6; as the lifting plate 17 continues to move upward, the lifting plate 17 lifts the tray 6 upward to separate the tray 6 from the belt 33, and at this time, the two positioning holes B9 located on the bottom surface of the tray 6 are respectively suspended on both sides of the lifting plate 17;

[0048] S24, control the moving part 20 of the screw nut pair 19 of the transfer device 3 to move backward, the moving part 20 drives the servo motor 21, the bracket 22 and the two support rods 23 to move backward synchronously, and the two support rods 23 move toward the tray 6. When the moving part 20 moves to the set distance, the controller controls the screw nut pair 19 to close. At this time, the positioning pins B24 on the two support rods 23 are respectively located directly below the two positioning holes B9 of the tray 6;

[0049] S25, the piston rod of the lifting cylinder 16 is controlled to retract downward, the piston rod drives the lifting plate 17 to move downward, and the lifting plate 17 drives the tray 6 to move downward. During the descending process, the two positioning holes B9 on the tray 6 are respectively sleeved on the positioning pins B24 of the two supporting rods 23. At this time, the tray 6 is just supported between the two supporting rods 23;

[0050] S26, control the moving part 20 of the screw nut pair 19 to move forward, the moving part 20 drives the servo motor 21, the bracket 22, and the support rod 23 to move forward synchronously, and the support rod 23 drives the tray 6 to move forward synchronously; when the moving part 20 moves to the set distance, the screw nut pair 19 is controlled to close; then the servo motor 21 is controlled to start, the servo motor 21 drives the bracket 22 to rotate, the bracket 22 drives the support rod 23 to rotate synchronously, and the support rod 23 drives the tray 6 to rotate synchronously. When the tray 6 rotates 90°, as shown in Figure 8 As shown, the controller controls the servo motor 21 to turn off, and at this time the tray 6 just moves to the top of the two cantilevers 29 of the shelf device 4. At the same time, the two positioning holes A8 on the tray 6 are respectively located above the positioning pins C30 of the two cantilevers 29. Fig. 9 As shown;

[0051] S27, control the piston rod of the lifting cylinder 27 of the shelf device 4 to move upward, the lifting plate 28 drives the two cantilevers 29 to move upward synchronously, the cantilever 29 drives the positioning pin C30 to move upward, and the two positioning pins C30 are respectively inserted into the two positioning holes A8 of the tray 6 from bottom to top; as the cantilever 29 continues to move upward, the two cantilevers 29 lift the tray 6 up, as shown in FIG. Fig.10 As shown, the tray 6 is separated from the support rod 23, thereby finally transporting the tray 6 and the product 32 thereon from the outside of the housing 2 to the shelf device 4, so that the robot arm can subsequently grab the product 32 on the tray 6;

[0052] Among them, it can be seen from step S2 that this circulation device can quickly transport the pallet 6 and the product 32 thereon from the outside of the outer shell 2 to the cantilever 29 of the shelving device 4 through the linkage cooperation of the conveying device 5, the transfer device 3 and the shelving device 4, thereby realizing the rapid loading of the product 32.

[0053] It can be seen from this that compared with manual material discharge in the workshop, this circulating device does not require frequent manual opening and closing of the window on the shell 2, thereby greatly reducing the workload of the workers. In addition, it also shortens the positioning time of the product 32, thereby shortening the loading time of the product 32, and further improving the loading efficiency of the product 32.

[0054] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.
