[0047] In addition, the technical features involved in the different embodiments of the present invention described later can be combined with each other as long as they do not conflict with each other.

[0048] See also Figures 1 to 5 , an embodiment of the present invention provides an automated rubber band wrapping device, comprising a screening device 1, a bundling device 2, and a product clamping and moving device 3;

[0049] The screening device 1 is used for screening and sorting rubber bands;

[0050] The bundling device 2 is provided on one side of the screening device 1 and is used to clamp the screened and sorted rubber bands and move them to a preset position before spreading them out.

[0051] The product clamping and moving device 3 is arranged on the other side of the strapping device 2. The product clamping and moving device 3 is used to clamp and move the product and cooperate with the strapping device 2 to strap the product using the stretched rubber band.

[0052] It should be noted that the screening device 1, the bundling device 2 and the product clamping and moving device 3 are distributed in sequence longitudinally, wherein the product clamping and moving device 3 also includes a transversely arranged product conveyor line 5 for conveying the products to be bundled; the product clamping and moving device 3 clamps the products to be bundled from the conveyor line and moves them to the corresponding working areas of the product clamping and moving device 3 and the bundling device 2; the bundling device 2 clamps the rubber bands screened and sorted by the screening device 1 and moves the rubber bands to the working area of ​​the bundling device 2 to stretch the rubber bands; after the rubber bands are stretched, the product clamping and moving device 3 drives the product to move toward the inside of the rubber band until the relative position of the rubber band reaches the predetermined position for product bundling, and the bundling device 2 loosens the rubber band to perform a bundling and sorting operation on the product.

[0053] In some embodiments of the present invention, the product gripping and moving device 3 can adjust the direction of the gripped product and cooperate with the strapping device 2 to strap the product in different positions and directions.

[0054] It should be noted that the placement and orientation of the products to be bundled on the conveyor line are different due to placement reasons or collisions with each other, and the product clamping and moving device 3 adjusts according to the placement orientation of the products and accurately clamps and fixes the products to be bundled. After the products to be bundled are clamped and fixed, the product clamping and moving device 3 will also rotate and adjust the orientation of the products to be bundled to adjust the bundling position of the products to be bundled, so that the products to be bundled can better enter the inner side of the stretched rubber band, making the bundling of the rubber band more accurate without causing tilted bundling.

[0055] In some embodiments of the present invention, the bundling device 2 includes a first clamping module 21 for clamping a rubber band; the first clamping module 21 includes a first pushing mechanism 211, the first pushing mechanism 211 drives a second pushing mechanism 212 to slide on the equipment frame 4, the second pushing mechanism 212 drives a third pushing mechanism 213 to slide on the equipment frame 4, and the third pushing mechanism 213 drives the clamping plate 214 to move up and down.

[0056] It should be noted that the first pushing mechanism 211 and the second pushing mechanism 212 are used to move the splint 214 to a preset position above the screening device 1. After the screening device 1 has screened and sorted the rubber bands, the third pushing mechanism 213 drives the splint 214 to move downward to clamp the rubber bands, and then the splint 214 is reset to achieve the clamping of the rubber bands.

[0057] In some embodiments of the present invention, the second pushing mechanism 212 and the third pushing mechanism 213 both include a slider 215 slidably connected to the equipment frame 4; the third pushing mechanism 213 also includes a lifting cylinder 2131, which is connected to the splint 214 and drives the splint 214 to move up and down.

[0058] The clamping plate 214 can be rotated to adjust the direction and position of the clamping plate 214 .

[0059] It should be noted that when the splint 214 clamps the rubber band and resets, the first pushing mechanism 211 contracts and drives the second pushing mechanism 212 to move to the left, and the slider 215 on the second pushing mechanism 212 and the third pushing mechanism 213 slides along the slide bar on the equipment frame 4, and then the third pushing mechanism 213 is driven by the second pushing mechanism 212 to move above the rubber band stretching area, and the third pushing mechanism 213 drives the splint 214 to move downward to the working area where the rubber band is stretched, and then the second pushing mechanism 212 contracts and drives the third pushing mechanism 213 and the splint 214 to move to the right, and the rubber band is put on the stretching part 222 in the merged state.

[0060] It should also be noted that in some embodiments of the present invention, an open groove is provided in the middle of the splint 214, and the rubber band is sleeved on both sides of the splint 214. Before the third pushing mechanism 213 drives the splint 214 to move downward, the splint 214 can be rotated to adjust the direction so that the end face of the open groove can face the rubber band stretching piece 222. As the splint 214 moves downward, the stretching piece 222 contacts one side of the rubber band, and then the second pushing mechanism 212 drives the third pushing mechanism 213 to retreat to allow the stretching piece 222 to pass through the open groove, and the stretching piece 222 enters the loop of the rubber band; the third pushing mechanism 213 then drives the splint 214 to move upward, so that the rubber band on the splint 214 can be smoothly sleeved on the stretching piece 222 in the closed state.

[0061] In some embodiments, the binding device 2 includes an expansion module 22 for expanding the rubber band; the expansion module 22 includes a limiting plate 221, on which a limiting groove 2211 and an expansion member 222 are provided; the limiting groove 2211 is used to limit the shape and size of the rubber band expanded by the expansion member 222.

[0062] The spreading member 222 includes four sector-shaped columns 2221 , which are driven by a cylinder provided on the limiting plate 221 to perform merging and spreading actions.

[0063] It should be noted that the expansion piece 222 is a cylinder in the combined state, and the end of the expansion piece 222 is a conical design, so that the rubber band can be more accurately put on the expansion piece 222; and when the rubber band is put on the expansion piece 222 in the combined state, the expansion piece 222 will be separated under the action of the cylinder and the rubber band will be stretched to form a square frame; the limiting plate 221 can limit the position and shape of the expansion piece 222 after it is separated.

[0064] It should also be noted that in some embodiments, the limit plate 221 and the equipment frame 4 are connected by a cylinder, and the limit plate 221 can move relative to the equipment frame 4. The limit plate 221 can cooperate with the product clamping and moving device 3 to better adjust the bundling position of the bundled product. At the same time, the movability of the limit plate 221 also provides another insertion action for the process of inserting the rubber band into the stretching piece 222.

[0065] In some embodiments of the present invention, the expansion module 22 also includes a bundling plate 223, which is provided with a receiving slot 2231, and the receiving slot 2231 is used to position and receive the product to be bundled; the bundling plate 223 can push the expanded rubber band from the expansion member 222 and bundle the product.

[0066] It should be noted that the bundling plate 223 and the limiting plate 221 are connected by a cylinder, and the bundling plate 223 can move relative to the limiting plate 221. When the product to be bundled enters the frame of the stretched rubber band and reaches the predetermined bundling position, the bundling plate 223 moves under the drive of the cylinder, pushing the rubber band on the stretching part 222 away from the stretching part 222 to achieve bundling of the product.

[0067] In other embodiments, when the product to be bundled enters the frame of the stretched rubber band and reaches the predetermined bundling position, the stretching member 222 begins to merge under the action of the cylinder, and the rubber band can also be put on the product to complete a bundling action.

[0068] The product clamping and moving device 3 includes a second clamping module 31 for clamping and fixing the product and a moving module 32 for moving the position of the product; the second clamping module 31 and the moving module 32 are rotatably connected to adjust the position of the product tied with the rubber band.

[0069] It should be noted that, in some embodiments of the present invention, the moving module 32 includes a first base plate 321 slidably connected to the equipment frame 4 bracket and a pulley mechanism 322 for driving the first base plate 321 to move, and a product lifting mechanism 323 is also slidably connected to the first base plate 321, and a rotatable second clamping module 31 for clamping the product is connected below the product lifting mechanism 323.

[0070] The present invention also provides a method for using an automatic rubber band wrapping device, comprising the following steps:

[0071] S1: After the mobile module 32 drives the second clamping module 31 to descend and clamp the product to be bundled, the mobile module then drives the second clamping module 31 and the product to be bundled to ascend and reset, and then adjusts the direction of the product to be bundled and moves the product to be bundled to the working area;

[0072] S2, screening device 1 screens and sorts the rubber bands;

[0073] S3, the first clamping module 21 drives the clamping plate 214 to reach the preset position, moves downward, and clamps the screened and sorted rubber bands, and then the first clamping module 21 drives the clamping plate 214 to move the rubber bands upward and reset;

[0074] S4, the first clamping module 21 drives the clamping plate 214 to move to a designated position and puts the rubber band on the expanded member 222 in the merged state;

[0075] S5, the stretching member 222 stretches the rubber band under the drive of the cylinder;

[0076] S6. The product to be bundled enters the receiving slot 2231 and the stretched rubber band under the drive of the moving module 32;

[0077] S7, the spreading member 222 is reset and cooperates with the bundling plate 223 to bundle the rubber band onto the product to be bundled under the drive of the cylinder;

[0078] S8, the moving module 32 moves the second gripping module 31 and the product outward, and then drives the second gripping module 31 and the product to rotate horizontally 180 degrees, and then repeats steps S2 to S7;

[0079] S9, the moving module 32 drives the second clamping module 31 and the bundled products to move outward to the conveyor line, the second clamping module 31 releases the bundled products, the moving module 32 resets and repeats steps S1 to S9.

[0080] It should be noted that in some embodiments of the present invention, the products are transported through a conveyor line, wherein a baffle 6 driven by a cylinder to rise and fall is provided on the conveyor line to isolate the products to be bundled. When the products to be bundled enter the product clamping area, the mobile module 32 drives the second clamping module 31 to move to the top of the products to be bundled and lowers the second clamping module 31 to clamp and fix the products; the clamped products to be bundled will be moved to the working area to be bundled under the drive of the mobile module 32 and adjust the direction and position; and after the products are bundled, the mobile module 32 will move the bundled products to the unloading line 7 for unloading, completing one bundling work, and then the mobile module 32 and the second clamping module 31 are reset and ready to start the next mobile clamping action.

[0081] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced therein.
