Description

Technical Field

[0001] The present application relates to the field of logistics technology, and in particular to a unloading device, an unloading method and a logistics conveying system. Background Art

[0002] Logistics refers to the entire process of planning, implementing, and managing the movement of raw materials, semi-finished products, finished products, and related information from their origin to their consumption locations through transportation, storage, and distribution to meet customer needs at the lowest possible cost. Goods must be unloaded at transshipment points.

[0003] The current unloading device directly places a conveying mechanism horizontally in the unloading compartment, and the other conveying mechanism is set at an angle, with one end placed on the ground and the other end placed below the output end of the horizontally placed conveying mechanism. The goods are then placed on the horizontally placed conveying mechanism, transported from the horizontally placed conveying mechanism to the inclined conveying mechanism, and finally transported out from the inclined conveying mechanism to complete the unloading process.

[0004] However, when the goods fall from the horizontal conveying mechanism to the inclined conveying mechanism, the goods instantly tilt downward and change direction significantly, which can easily cause the goods to shake violently, so that the goods are not transported through another conveying mechanism, but directly roll down along its inclined surface. The direct rolling method causes the goods to directly collide violently with the ground or the receiving frame, increasing the risk of damage to the goods. Summary of the Invention

[0022] The second object of the present invention is to provide a discharging method, comprising the following steps:

[0023] S1: placing the material on the first conveying mechanism and transferring it to the first transition plate;

[0024] S2: After the material is transferred to the first transition plate, the infrared sensor detects the cargo, and the driving unit drives the first transition plate to rotate around the hinge point.

[0034] 1. The present application hinges a first transition plate at the output end of the first transmission mechanism, and a second transition plate is provided at the input end of the second transmission mechanism. After the material is transmitted from the first transmission mechanism to the first transition plate, the infrared sensor monitors the goods, and the driving unit drives the first transition plate to rotate around the hinge point and overlaps it with the second transition plate. The goods then slide to the second transition plate and then slide to the second transmission mechanism.

[0035] 2. The present application closes or opens the first transmission mechanism by setting the first tactile part and the second tactile part, and making the two overlap and contact each other. When the first transition plate cooperates with the second transition plate to transfer the goods, the first transmission mechanism stops to prevent other goods on the first transmission mechanism from falling.

[0036] 3. This application sets up a baffle and uses a trigger mechanism to block or release the goods, making the goods more stable during transitional transmission and further improving the protection effect of the goods. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0048] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0049] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 9As shown, an embodiment of the present application proposes a unloading device, comprising: a bracket 1, on which a first transmission mechanism 2 and a second transmission mechanism 3 are provided, the first transmission mechanism 2 is horizontally arranged, and the second transmission mechanism 3 is inclined; a first transition plate 4 and a second transition plate 5, one end of the first transition plate 4 is hinged to the output end of the first transmission mechanism 2, and one end of the second transition plate 5 is fixed to the input end of the second transmission mechanism 3, and the first transition plate 4 can be overlapped on the second transition plate 5 by rotating around the hinge point; a driving part 6, which is provided on the first transmission mechanism 2 and is used to drive the first transition plate 4 to rotate around the hinge point; an infrared sensor 7, which is provided on the first transition plate 4 and is used to monitor the goods on the first transition plate 4, when the infrared sensor 7 detects the goods, the driving part 6 drives the first transition plate 4 to rotate around the hinge point and overlap the second transition plate 5, when the infrared sensor 7 does not detect the goods, the driving part 6 drives the first transition plate 4 to rotate and reset around the hinge point; a first touch part 8, which is provided on the first transmission mechanism 2;The support rod 9 is provided on the first transition plate 4. The end of the support rod 9 is provided with a second touch portion 10. When the first touch portion 8 overlaps with the second touch portion 10, the first transmission mechanism 2 realizes transmission. In order to make the device more reasonable, preferably, the first touch portion 8 is a pressure button for controlling the opening or closing of the first transmission mechanism 2, and the second touch portion 10 is a pressing rod. When the first touch portion 8 overlaps with the second touch portion 10, the pressing rod presses the pressure button. At this moment, the first transmission mechanism 2 is in a transmission state. At this time, the transmission surface of the first transition plate 4 and the first transmission mechanism 2 are flush with each other, and the transmission surface of the second transition plate 5 and the second transmission mechanism 3 are flush with each other. The infrared sensor 7 is electrically connected to the driving unit 6 through the controller. The infrared sensor The monitoring range of 7 is the entire surface of the first transition plate 4. When the goods are transferred from the first transmission mechanism 2 to the first transition plate 4, the infrared sensor 7 detects the goods, and the driving unit 6 drives the first transition plate 4 to rotate around the hinge point. When the first transition plate 4 rotates around the hinge point, the first touch portion 8 is disconnected from the second touch portion 10, and the pressing rod releases the pressure on the pressed button, and the first transmission mechanism 2 stops transmitting. When the first transition plate 4 overlaps with the second transition plate 5, the driving unit 6 stops driving (the driving unit 6 is a stroke operation, and the stroke operation includes a reciprocating first stroke and a second stroke. The first stroke starts when the first transition plate 4 is flush with the first transmission mechanism 2 and ends when the first transition plate 4 overlaps with the second transition plate 5. The second stroke The journey starts when the first transition plate 4 and the second transition plate 5 overlap, and ends when the first transition plate 4 is flush with the first transmission mechanism 2. When the infrared sensor 7 detects the goods, the drive unit 6 drives a journey, and the first transition plate 4 and the second transition plate 5 overlap. At this time, the drive unit 6 is in a standby state). After the first transition plate 4 and the second transition plate 5 overlap, the first transition plate 4 is in an inclined state, and the goods slide onto the second transition plate 5 in the inclined state. The goods then slide to the second transmission mechanism 3 through the second transition plate 5 for re-transmission. When the goods leave the first transition plate 4, the infrared sensor 7 can no longer detect the goods, the drive unit 6 is turned on again, and the first transition plate 4 rotates around the hinge point to reset. When the first transition plate 4 After rotation and reset, the first tactile portion 8 and the second tactile portion 10 are in contact. The pressing rod presses the pressure button again, and the first conveying mechanism 2 resumes normal transmission. The overall structure of the device ensures that during transmission, the goods do not fall directly from the first conveying mechanism 2 onto the second conveying mechanism 3. Instead, the goods are first transferred to the first transition plate 4, then slide through the first transition plate 4 to the second transition plate 5, and then slide to the second conveying mechanism 3. This sliding method of transitional transmission of the goods is relatively gentle, preventing violent vibrations during the transfer of the goods between the first conveying mechanism 2 and the second conveying mechanism 3, causing the goods to roll directly along the conveying surface of the second conveying mechanism 3, thereby reducing the risk of damage to the goods.

[0050] like Figure 1 、 Figure 3 and Figure 7 As shown, in some embodiments, a vertical rod 11 is provided at one end of the first transition plate 4 away from the hinge point, a sleeve 12 is rotatably sleeved on the vertical rod 11, a baffle 13 is provided on the sleeve 12, and a trigger mechanism 14 is provided between the first transition plate 4 and the second transition plate 5. When the first transition plate 4 and the second transition plate 5 overlap, the trigger mechanism 14 drives the sleeve 12 to rotate, and when the first transition plate 4 is away from the second transition plate 5, the trigger mechanism 14 drives the sleeve 12 to rotate and reset. In order to make the device more reasonable, preferably, when the first transition plate 4 is away from the second transition plate 5, the baffle 13 is perpendicular to the transmission direction of the first transition plate 4 to play a role in blocking the goods. When the goods are transmitted from the first transmission mechanism 2 to the first transition plate 4, the baffle 13 blocks the goods to prevent the first transition plate 4 from When the plate surface gradually tilts during the rotation process and does not contact the second transition plate 5, some relatively smooth goods slide directly from the first transition plate 4 to the second transition plate 5. At this time, when the first transition plate 4 is not overlapped with the second transition plate 5, there is still a height difference between the two to avoid the goods from falling directly, resulting in excessive vibration amplitude. The goods roll directly along the transmission surface of the second transmission mechanism 3. When the first transition plate 4 and the second transition plate 5 are overlapped by the baffle 13, the trigger mechanism 14 drives the sleeve 12 to rotate, thereby releasing the baffle 13 from blocking the goods, and the goods slide to the second transmission mechanism 3. After the goods slide, the first transition plate 4 is reset away from the second transition plate 5, and the trigger mechanism 14 drives the sleeve 12 to rotate and reset, so that the baffle 13 can block the next goods.

[0051] like Figure 3 and Figure 7As shown, in some embodiments, the trigger mechanism 14 includes a fixed seat 1401, a shaft 1402, a transmission bevel gear 1403, a driven bevel gear 1404 and a trigger plate 1405, wherein: the fixed seat 1401 is fixed on the first transition plate 4, the trigger plate 1405 is fixed on the second transition plate 5, the shaft 1402 rotates through the fixed seat 1401, the driven bevel gear 1404 is fixed on the sleeve 12, the transmission bevel gear 1403 is fixed on one end of the shaft 1402 and meshes with the teeth of the driven bevel gear 1404, the other end of the shaft 1402 is fixed with a first gear 1406, and the first transition plate 1405 is fixed on the second transition plate 5. A trigger rod 1407 is vertically movable through the ferry plate 4, and a first rack 1408 is provided on the top of the trigger rod 1407, which is meshed with the teeth of the first gear 1406. A first limit plate 1409 is fixed on the trigger rod 1407, and a first spring 1410 is provided between the first limit plate 1409 and the first transition plate 4. When the first transition plate 4 rotates around the hinge and is about to overlap with the second transition plate 5, the trigger rod 1407 first contacts the trigger plate 1405. As the first transition plate 4 continues to rotate, the trigger rod 1407 slides under the resistance force, and the first The limiting plate 1409 squeezes the first spring 1410, and the trigger rod 1407 slides to drive the first rack 1408 to move. When the first rack 1408 moves, it engages with the teeth of the first gear 1406, thereby driving the shaft 1402 to rotate. When the shaft 1402 rotates, it drives the transmission bevel gear 1403 to rotate. When the transmission bevel gear 1403 rotates, it engages with the teeth of the driven bevel gear 1404, thereby driving the sleeve 12 to rotate. When the first transition plate 4 is about to overlap with the second transition plate 5, the trigger rod 1407 conflicts with the trigger plate 1405. As the first transition plate 4 When the first transition plate 4 overlaps with the second transition plate 5, the contact force between the trigger rod 1407 and the trigger plate 1405 increases, and the sliding distance of the trigger rod 1407 increases, thereby increasing the rotation amplitude of the sleeve 12 and the opening and closing degree of the baffle 13. When the first transition plate 4 overlaps with the second transition plate 5, the baffle 13 is completely opened and closed to facilitate the sliding of the goods out of the first transition plate 4. When the first transition plate 4 rotates and resets to move away from the second transition plate 5, the contact between the trigger rod 1407 and the trigger plate 1405 is released. Under the elastic force of the first spring 1410, the trigger rod 1407 slides and resets, thereby causing the sleeve 12 to rotate and reset.

[0052] like Figure 9As shown, in some embodiments, a connecting rod 15 is vertically movable through the support rod 9, and a limit block is constructed at the top end of the connecting rod 15. The second tactile portion 10 is arranged at the bottom end of the connecting rod 15, and a second limit plate 16 is fixed on the connecting rod 15. A second spring 17 is provided on the connecting rod 15 between the second limit plate 16 and the support rod 9. When the second tactile portion 10 overlaps and contacts the first tactile portion 8, the connecting rod 15 slides under the action of the resistance force, and the second limit plate 16 squeezes the second spring 17. The elastic force of the second spring 17 is used to resist, so that the second tactile portion 10 is more stable when in contact with the first tactile portion 8, and at the same time, it also avoids the second tactile portion 10 from rigidly contacting the first tactile portion 8, which may cause damage.

[0053] like Figure 8 As shown, in some embodiments, the driving part 6 includes a second gear 601, a second rack 602 and an electric push rod 603, wherein: a guide rod 604 is rotated and passed through the first transmission mechanism 2, the number of the guide rods 604 is two and the two guide rods 604 are symmetrically rotated and passed through the first transmission mechanism 2, the first transition plate 4 is arranged between the opposite sides of the two guide rods 604, the first transition plate 4 is fixed on the guide rod 604, the second gear 601 is fixed on the guide rod 604, the electric push rod 603 is arranged on the first transmission mechanism 2, the second rack 602 is arranged at the piston end of the electric push rod 603 and is engaged with the teeth of the second gear 601, the electric push rod 603 does work, and its piston end pushes the second rack 602 to move, and when the second rack 602 moves, it engages with the teeth of the second gear 601 to achieve the effect of driving the guide rod 604 to rotate, so as to achieve the effect of driving the first transition plate 4 to rotate around the hinge point, and the piston end of the electric push rod 603 retracts or extends to meet the rotation or reset stroke of the first transition plate 4.

[0054] like Figure 10 As shown, in some embodiments, a groove 18 is provided on the first transition plate 4, and a plurality of rollers 19 are arranged in an array in the groove 18. Through the arrangement of the rollers 19, the goods can slide more smoothly to the first transition plate 4 under the transmission of the first transmission mechanism 2. At the same time, it is also convenient for some goods with rough surfaces and high friction to slide smoothly from the first transition plate 4 to the second transition plate 5.

[0055] like Figure 4 and Figure 10 As shown, in some embodiments, a first overlapping groove 20 is provided at one end of the first transition plate 4 away from the hinge point, and a second overlapping groove 21 is provided at the free end of the second transition plate 5 to overlap with the first overlapping groove 20. By opening the first overlapping groove 20 and the second overlapping groove 21, after the first transition plate 4 and the second transition plate 5 are overlapped, the plate surfaces of the first transition plate 4 and the second transition plate 5 are flush, so that the vibration amplitude of the goods is smaller during the sliding process, and the transition transportation is smoother.

[0056] The present application also proposes a discharging method of a discharging device, comprising the following steps:

[0057] S1: placing the material on the first conveying mechanism 2 and conveying it to the first transition plate 4;

[0058] S2: After the material is transferred to the first transition plate 4, the infrared sensor 7 detects the cargo, and the driving unit 6 drives the first transition plate 4 to rotate around the hinge point. At this time, when the first transition plate 4 rotates, the first touch portion 8 is disconnected from the second touch portion 10, and the first transmission mechanism 2 stops transmission. During the rotation of the first transition plate 4, the baffle 13 blocks the cargo to prevent relatively smooth cargo from directly sliding off the first transition plate 4 when the first transition plate 4 is not overlapped with the second transition plate 5;

[0059] S3: After the first transition plate 4 and the second transition plate 5 are overlapped, the trigger mechanism 14 is activated, the sleeve 12 rotates and resets, and the baffle 13 releases the obstruction of the goods. The goods slide onto the second transition plate 5 due to the inclination of the first transition plate 4, and then slide onto the second transmission mechanism 3 via the second transition plate 5, thereby realizing the transition of the goods from the first transmission mechanism 2 to the second transmission mechanism 3. Finally, the goods slide to the second transmission mechanism 3 for further transmission;

[0060] S4: When the goods slide out of the first transition plate 4, the infrared sensor 7 cannot detect the goods, and the driving unit 6 drives the first transition plate 4 to rotate around the hinge point and reset. When the first transition plate 4 is reset, the baffle 13 is reset again to form a blocking state, the second tactile part 10 overlaps with the first tactile part 8, and the first transmission mechanism 2 realizes transmission again.

[0061] like Figure 1 、 Figure 5 and Figure 6As shown, the present application also proposes a logistics conveying system, including the above-mentioned unloading device, and also includes: a car plate 22; located at the output end of the second transmission mechanism 3, a material box 32 is provided on the car plate 22, and the bottom of the material box 32 is structured with a pad. The structure of the pad allows a plurality of material boxes 32 to be overlapped and leave a gap between them, which is convenient for subsequent forklift operations; a gantry 23, which is provided on the car plate 22, and the opposite sides of the inner wall of the gantry 23 are provided with a slide groove 24 along its height direction; a screw rod 25, which rotates vertically and passes through the car plate 22 and the gantry 23, and one end of the screw rod 25 is connected to a servo motor 26 provided on the gantry 23; a mounting plate 27, which is threadedly sleeved on the screw rod 25, and the two ends of the mounting plate 27 are respectively slidably inserted into the two slide grooves 24; an insertion rod 28, which has a U-shaped structure, and the insertion rod 28 The movable plate 27 passes through the mounting plate 27. When the unloaded goods need to be transported and transferred, the car plate 22 is pushed to the output end of the second transmission mechanism 3. The servo motor 26 works, and its output shaft drives the screw rod 25 to rotate. Under the action of the screw rod 25 thread and the sliding limit of the slide 24, the mounting plate 27 is driven to move vertically. When receiving materials, the position of the mounting plate 27 is first adjusted, and then the insertion rod 28 is movably inserted at the bottom of the material box 32. The servo motor 26 works and then drives the screw rod 25 to rotate, thereby adjusting the mounting plate 27 upward, so that the insertion rod 28 lifts the material box 32 to a certain height, so that the staff does not need to bend over when transferring the materials on the second transmission mechanism 3 to the material box 32, thereby reducing the labor of the staff. Figure 5 As shown, there are three material boxes 32. When loading materials, the insertion rod 28 can be adjusted to lift the material box 32 at the top. When the material box 32 at the top is full, the mounting plate 27 is adjusted upward by a certain distance to take out the material box 32 at the bottom, and then the filled material box 32 is moved and placed on the vehicle plate 22. In the actual material transfer, multiple material boxes 32 can be placed on the vehicle plate 22, and during the loading process, the material box 32 being loaded can always maintain a certain height to facilitate the staff to release the material. After multiple material boxes 32 are full, batch transfer is carried out.

[0062] like Figure 5 and Figure 6 As shown, in some embodiments, two connecting seats 29 are provided on the top of the portal frame 23, and a receiving frame 30 is hinged on the two connecting seats 29, and a receiving cloth 31 is provided on the receiving frame 30. When loading, the receiving frame 30 can be rotated around the hinge point so that the receiving frame 30 is overlapped on the portal frame 23, the receiving frame 30 remains in a horizontal state, and the receiving cloth 31 is located above the second transmission mechanism 3. The receiving cloth 31 can temporarily place the goods transmitted on the second transmission mechanism 3, so that the staff has enough time to place the goods neatly in the material box 32, so that the material box 32 can make full use of the storage space.
