The flipping feeding mechanism is used to identify, screen and flip the delivered products. It includes a receiving platform that is adapted to the discharge end of the linear vibrating track, an image recognition sensor for detecting the positive and negative states of the products, and a flipping component for flipping the reversed products.

[0005] Furthermore, the linear vibrating track of the vibrating feeding mechanism is installed above the linear vibrator. Fiber optic sensors and air nozzles are respectively installed on the linear vibrating track. The fiber optic sensors are used to control the start and stop of the vibrating plate by monitoring the products on the linear vibrating track. The air nozzles are configured at the discharge end of the linear vibrating track to provide forward force to the discharged products.

[0006] Furthermore, an adsorption hole is provided on the linear vibration track, and the lower part of the adsorption hole is connected to an air intake connector installed below the linear vibration track. The air intake connector is connected to an external vacuum generator through a vacuum pipeline.

[0007] Furthermore, the bottom of the slope of the linear vibrating track has a stop of a predetermined height so that the upper layer of material in the linear vibrating track can fall smoothly into the return track below.

[0008] Furthermore, the receiving platform of the flipping feeding mechanism is installed on the swing platform cylinder and controlled by its output. The swing platform cylinder is adjustablely installed on one side of the swing cylinder fixing part two. The swing cylinder fixing part two is connected to the top of the swing cylinder fixing part one through a keyway and a waist hole.

[0009] Furthermore, the reverse material flipping assembly is installed on the other side of the swing cylinder fixing component two, including a swing cylinder, a flipping plate controlled and connected by the swing cylinder, and a suction cup installed on the flipping plate.

[0010] Furthermore, the swing cylinder is fixed to the flip base plate, and the flip base plate is installed on the other side of the swing cylinder fixing component two through the waist hole and the fixing component.

[0011] Furthermore, the output shaft of the swing cylinder is connected to the tilting plate in sequence via a coupling, a linear bearing, and a tilting shaft.

[0012] Furthermore, the first feeding position is when the receiving platform swings to a horizontal state, and the second feeding position is when the suction cup of the flipping plate picks up the product and flips it to a horizontal state.

[0013] This utility model discloses an automatic feeding device for sheet products. It uses image recognition technology to determine the front and back of the sheet, and uses a reverse material flipping component to pick up and flip the reverse material on the receiving table.

[0015] The present invention will now be described in detail with reference to the accompanying drawings.

[0016] Example 1 like Figure 1 As shown, an automatic feeding device for sheet products is used to feed such... Figure 4 The sheet products shown are conveyed to the equipment for subsequent production. The automatic feeding device includes a vibratory feeder 1, a vibratory feeding mechanism 2, and a flipping feeding mechanism 3. The vibratory feeder 1 is installed at the front, and the vibratory feeding mechanism 2 and the flipping feeding mechanism 3 are arranged sequentially behind it. The vibratory feeding mechanism 2 is located at the discharge end of the vibratory feeder 1 and is used to arrange the products conveyed by the vibratory feeder 1 neatly and convey them to the next station. The flipping feeding mechanism 3 is located at the discharge end of the vibratory feeding mechanism 2 and is used to distinguish the front and back of the products and flip the front and back products for feeding separately.

[0017] The specific structural composition of the vibrating feeding mechanism 2 and the tilting feeding mechanism 3 will be described in detail below.

[0018] The vibrating feeding mechanism 2 is as follows Figure 2 As shown, the system includes a linear vibrating fixing plate 21 and a linear vibrating fixing plate 22. The linear vibrating fixing plate 22 is fixedly installed via a base. The linear vibrating fixing plate 21 is connected to the linear vibrating fixing plate 22 via a key and a slot, allowing the linear vibrating fixing plate 21 to be adjusted vertically relative to the linear vibrating fixing plate 22. This ensures that the overall height of the mechanism can be adjusted, thereby ensuring that the height of the linear vibrating track 24 is consistent with the discharge port of the vibrating plate 1. A linear vibrator 23, which provides power for product conveying, is installed above the linear vibrating fixing plate 21. The linear vibrator 23 is connected to the linear vibrating track 24 and the return track 25 via two pads. The linear vibrating track 24 is used to convey products, and its conveying surface is a slope with a certain inclination. The return track 25 is located below the slope of the linear vibrating track 24 to collect products that fall from the linear vibrating track 24. The bottom of the sloping surface of the vertical vibration track 24 has a suitable height of retaining edge design, so that when products are stacked on the vertical vibration track 24, the products stacked on top can automatically fall into the return track 25 below for return. The vertical vibration track 24 has threaded holes on the side and bottom for installing fiber optic sensor 26, air nozzle 27 and suction connector, respectively; the fiber optic sensor 26 is used to monitor whether the number of products on the vertical vibration track 24 is sufficient, thereby controlling the start and stop of the vibratory feeder 1; the air nozzle 27 is located at the end of the vertical vibration track 24 to provide forward force for the discharged products; the suction connector is installed below the vertical vibration track 24, one end of which is connected to a vacuum generator through a vacuum pipeline, and the other end is connected to an adsorption hole opened on the vertical vibration track 24, so that the thin sheet products are firmly adsorbed in the vertical vibration track 24 through vacuum action.

[0019] The flipping feeding mechanism 3 is as follows Figure 3As shown, it includes a swing cylinder fixing component 1 31, a swing cylinder fixing component 2 32, a swing platform cylinder 33, a receiving platform 34, a photoelectric sensor 35, an image recognition sensor 36, and a reverse material flipping assembly for flipping the reversed products on the receiving platform 34.

[0020] The first swing cylinder fixing component 31 is fixedly installed via the base below. The second swing cylinder fixing component 32 is connected above the first swing cylinder fixing component 31 via a keyway and a waist hole, allowing the second swing cylinder fixing component 32 to be adjusted up and down relative to the first swing cylinder fixing component 31. The swing platform cylinder 33 is fixed to one side of the second swing cylinder fixing component 32 via a waist hole and an adjustment plate, facilitating individual adjustment of the height of the swing platform cylinder 33. The receiving platform 34 is fixed to the swing platform cylinder 33 via a receiving platform fixing plate 34a, enabling the receiving platform 34 to swing under the drive of the swing platform cylinder 33. The photoelectric sensor 35 is fixed to the receiving platform 34 via a sensor fixing plate, and together with the image recognition sensor 36, monitors the incoming product status.

[0021] The reverse material flipping assembly includes a swing cylinder 371, a flipping plate 372 controlled and connected by the swing cylinder 371, and a suction cup 373 mounted on the flipping plate 372. The swing cylinder 371 is fixed to the flipping base plate 374 by two vertical plates. The flipping base plate 374 is mounted on the other side of the swing cylinder fixing component 32 through a waist hole and a fixing member, which facilitates the individual adjustment of the height of the swing cylinder 371. The output shaft of the swing cylinder 371 is connected to the flipping plate 372 in sequence via a coupling 375, a linear bearing 376, and a flipping shaft 377. The suction cup 373 is fixed on the flipping plate 372 and is used to pick up the reverse material and flip it.

[0022] The automatic feeding device for sheet products in this embodiment has the following design principle and operation process: The products enter the linear vibrating track 24 of the vibrating feeding mechanism 2 sequentially from the vibrating plate 1. Under the action of the linear vibrator 23, they are conveyed forward in an orderly manner and finally enter the receiving table 34 of the flipping feeding mechanism 3 through the discharge end of the linear vibrating track 24. At this time, the photoelectric sensor 34 and the image recognition sensor 35 cooperate to monitor the orientation of the incoming material on the receiving table, thereby placing different incoming materials in different feeding positions. If the incoming material is in the forward direction, the receiving table 33 rotates to the first feeding position (the receiving table is in a horizontal state) to feed the material and blocks the incoming material from the rear to prevent stacking. If the incoming material is in the reverse direction, the receiving table 33 first rotates to the first feeding position (the receiving table is in a horizontal state), and then the swing cylinder 371 installed on the other side is activated to control the flipping plate 372 to rotate and make the suction cup side rotate to the top of the receiving table 33. After the product is sucked up by the suction cup 373, it is flipped to the second feeding position (the flipping plate is in a horizontal state) to feed the material.
