Description

Technical Field

[0001] This utility model relates to the field of pallet technology, and in particular to a pallet flipping device. Background Technology

[0002] Pallets, as standardized tools for carrying goods in logistics transportation and warehousing management, are widely used in various fields due to their "unitization, standardization, and efficiency," becoming a core carrier connecting production, warehousing, transportation, and distribution. In logistics operations, due to practical needs, pallets carrying goods need to be flipped 180° or 90° to solve problems such as "direction adjustment," "pallet changing," and "loading and unloading assistance" during the flow, storage, and processing of goods. During the flipping process (especially a 180° flip), the pallet and goods undergo a drastic change in the direction of gravity (from vertically downward to upward or lateral). Without clamping and fixing, the lack of constraint between the goods and the pallet, and between the pallet and the flipping device, makes it easy for relative sliding to occur due to inertia. Based on this, this utility model proposes a pallet flipping device. Utility Model Content

A vertical groove is formed on the flipping frame away from the rotating shaft and perpendicular to the center of the transverse groove. A plurality of clamping components are slidably mounted on the transverse and vertical grooves respectively. An opening and closing mechanism is provided below the transverse groove, which drives the clamping components symmetrically mounted on the transverse groove to move.

[0022] like Figure 1-4 As shown, a pallet tilting device includes a rotating shaft 1, on which a tilting frame 6 is vertically mounted. The rotating shaft 1 is driven to rotate by a power mechanism. The power mechanism includes a motor 5, which is connected to the rotating shaft 1 via a coupling 4. Bearings 3 are respectively mounted at both ends of the rotating shaft 1, and the bearings 3 are installed in bearing seats 2. The motor 5 is mounted on a motor mounting base.

[0023] A horizontally distributed rear baffle 7 is installed on the upper surface of the tilting frame 6 near the rotating shaft 1. A horizontal sliding groove 8 is formed in the middle of the tilting frame 6 along the horizontal direction. A vertical sliding groove 10 is formed in the tilting frame 6 away from the rotating shaft 1 and perpendicular to the center of the horizontal sliding groove 8. The vertical sliding groove 10 is located on the side away from the rear baffle 7. Several clamping components 9 are slidably installed on the horizontal sliding groove 8 and the vertical sliding groove 10, respectively. The vertical sliding groove 10, together with the rear baffle 7, clamps the pallet 12 in the front-to-back direction. The two symmetrical clamping components 9 on the horizontal sliding groove 8 clamp the pallet 12 on the left and right sides, preventing the goods from falling or being damaged due to the sliding force generated by gravity and inertia of the pallet 12 during the tilting process, thereby improving the stability of the tilting process.

[0024] An opening and closing mechanism is installed below the horizontal slide 8. The opening and closing mechanism drives the clamping components 9, which are symmetrically installed on the horizontal slide 8, to move (mainly for opening and closing operations). The clamping components 9, which are installed on the vertical slide 10, are driven to move (moving in the front and back direction) below the vertical slide 10 through a lead screw mechanism.

[0025] The clamping assembly 9 includes a fixed base 901 at the bottom for fixing the opening and closing mechanism or the lead screw mechanism. A sliding vertical rod 902 is installed at the upper center of the fixed base 901. After passing through the horizontal slide groove 8 / vertical slide groove 10, a clamping plate 904 is installed on the sliding vertical rod 902. A piezoelectric force sensor is installed on the clamping plate 904. The piezoelectric force sensor utilizes the property of piezoelectric materials (such as quartz crystals) to generate electric charge when subjected to force, converting the force signal into an electrical signal to directly measure the clamping force between the contact surface between the clamping plate 904 and the tray 12, avoiding excessive force (damaging the tray 12) or insufficient force (loosening and failure). The outer periphery of the sliding vertical rod 902 is provided with a limiting groove 903 that cooperates with the horizontal slide groove 8 / vertical slide groove 10 to prevent it from jumping up and down during movement, allowing it to slide along the direction of the slide groove.

[0026] The opening and closing mechanism includes a base 13, with a rotating disk 14 mounted at the upper center of the base 13. A motor 3, which drives the rotating disk 14 to rotate, is mounted at the bottom of the base 13. Rotating rods 15 are symmetrically mounted on the rotating disk 14. Limiting components are symmetrically mounted on the left and right sides of the base 13. Moving rods 17 are slidably mounted on the limiting components. The rotating rods 15 and moving rods 17 are hinged together by a connecting rod 16. A mounting hole 19 is installed at the end of the moving rod 17 away from the connecting rod 16. The limiting components include symmetrically mounted limiting blocks 18, which are inverted L-shaped structures, restricting the moving rods 17 to move along a straight line and improving the stability of the sliding process. The top of the limiting blocks 18 is fixedly connected to the bottom of the flipping frame 6. Specifically, the forward and reverse rotation of the rotating disk 14 enables the forward and reverse rotation of the rotating rod 15, thereby enabling the moving rod 17 to move inward and outward under the restriction of the limiting block 18 via the connecting rod 16, thus satisfying the opening and closing movement of the clamping assembly 9.

[0027] The lead screw mechanism includes a lead screw 21, with a lead screw block 22 threadedly connected to the lead screw 21. Mounting seats 20 are rotatably mounted at both ends of the lead screw 21. One end of the lead screw 21 extends through the mounting seat 20 and is connected to a motor 23. The top of the mounting seat 20 is fixedly connected to the bottom of the tilting frame 6. According to the lead screw principle, by rotating the lead screw 21 forward and backward, the lead screw block 22, under the combined action of the clamping assembly 9 and the sliding groove, restricts its back-and-forth movement on the lead screw 21.

[0028] An electrical control cabinet 11 is installed on one side of the flipping frame 6. The electrical control cabinet 11 is electrically connected to a piezoelectric force sensor, motor 5, motor 23, and motor 3. Specifically, the piezoelectric force sensor transmits the detected clamping force to the electrical control cabinet 11, which controls the operation of motors 23 and 3 to achieve automated clamping and releasing of the pallet 12.

[0029] The operation process of this utility model is as follows:

[0030] First, the flipping frame 6 is in a horizontal position; then, the tray 12 is placed on the flipping frame 6 and pressed against the rear baffle 7; then, the clamping components 9 on the horizontal slide 8 are adjusted by the opening and closing mechanism to clamp the left and right end faces of the tray 12, and the screw mechanism is adjusted by the clamping components 9 on the vertical slide 10 to cooperate with the rear baffle 7 to clamp the front and rear end faces of the tray 12; finally, the motor 5 is started, the rotating shaft 1 rotates, and the tray 12 is flipped together.

[0031] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
