Description

Technical Field

[0001] This invention relates to the field of automated production line technology, and more specifically to an automatic flipping conveyor device. Background Technology

[0002] In mechanized manufacturing, products need to be transported between different manufacturing equipment. Conveying devices are important channels connecting these equipment. After processing, each piece of equipment cannot stack or output the finished product, nor can it properly transfer it to downstream equipment. For equipment requiring feeding, manual feeding is often used. For example, in the packaging of bottled chocolates, the bottles need to be fed into the packaging machine at a consistent angle. In traditional methods, workers manually flip and arrange the bottles. Even with skilled workers, the efficiency is only 100-180 bottles per minute, indicating low productivity and difficulty in meeting hygiene standards. Summary of the Invention

[0003] This invention provides an automatic flipping conveyor device that uses a vertical conveying mechanism and a straight conveying mechanism to gradually sort out the scattered and discontinuous cone-shaped materials sent from the upstream conveyor belt, and finally convey them to the downstream equipment in a uniform manner, thereby improving work efficiency.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an automatic flipping conveyor device, disposed between an upstream conveyor belt and a downstream conveyor belt, for automatically flipping the conveyed conical material, comprising: a vertical conveying mechanism, wherein the vertical conveying mechanism is composed of two belts in the same horizontal plane, and a conveying channel is formed between the two belts, the receiving end of the conveying channel being located below the output end of the upstream conveyor belt; a straightening conveying mechanism, wherein the straightening conveying mechanism is composed of a horizontal conveyor belt and a combing channel disposed above the horizontal conveyor belt along the conveying direction, and limiting strips are provided on both sides of the combing channel, each of the limiting strips corresponding to the two sides of the conveying channel away from the upstream conveyor belt; the working surface of the horizontal conveyor belt is lower than the horizontal plane where the belt is located; the horizontal conveyor belt is provided with a first drive motor, and the vertical conveying mechanism is provided with a second drive motor, the second drive motor driving the two belts to rotate synchronously through a synchronous transmission mechanism; and a controller, wherein the controller is electrically connected to the first drive motor and the second drive motor.

[0005] Preferably, the device further includes an adjustment bracket for simultaneously fixing each of the limiting strips to the machine body. The adjustment bracket is arranged horizontally above the combing channel and has an elongated hole perpendicular to each of the limiting strips. Each of the limiting strips is fixed to the bottom of the adjustment bracket by bolts passing through the elongated holes. Each of the limiting strips has a sliding strip on one side corresponding to the combing channel.

[0006] Preferably, the vertical conveying mechanism further includes a pair of clamps respectively disposed on both sides of the conveying channel, the adjacent side walls of the two clamps being arranged parallel to each other, the two belts rotating around the corresponding clamps via their respective pulley sets, and the adjacent outer wall of each clamp being provided with a belt groove corresponding to the belt; the pulley set of each belt includes a front guide wheel disposed on the clamp near the end of the upstream conveyor belt, and a rear guide wheel disposed on the clamp near the end of the horizontal conveyor belt; the synchronous transmission mechanism consists of a first bevel gear coaxially connected to the two front guide wheels, and two second bevel gears coaxially arranged on the output shaft of the second drive motor, the two second bevel gears meshing and transmitting power with their respective corresponding first bevel gears.

[0007] Preferably, the two second bevel gears are nested on the output shaft of the second drive motor via a keyway bushing, and the bushing has a radially penetrating fixing screw in the middle.

[0008] Preferably, the controller is equipped with a first speed regulator and a second speed regulator corresponding to the first drive motor and the second drive motor, for adjusting the conveying speed of the conveying channel and the combing channel respectively.

[0009] The beneficial effects of this invention are: it grades and combs tapered materials, ultimately conveying them in an orderly manner to the downstream conveyor belt via a horizontal conveyor belt. Specifically, the upper conveyor belt throws the scattered materials out of the output end, and the materials fall into the conveyor channel in a parabolic trajectory. Since the distance between the belts on both sides of the conveyor channel is between the diameter of the small end and the large end of the material, after the material falls into the conveyor channel, the small end hangs down naturally, while the large end is caught on the upper part of the belt. It is conveyed by the two belts in the conveyor channel at a vertical angle with the small end facing down. At the end of the conveyor channel, when it encounters the horizontal conveyor belt, the bottom of the material is blocked by the input end of the horizontal conveyor belt. At this time, the large end of the material continues to be conveyed by the belt, thus causing the material to fall onto the horizontal conveyor belt with the large end facing forward. Under the constraint of the limiting strips on both sides of the combing channel, the angle will not change due to rolling. The distance between the two limiting strips is slightly larger than the diameter of the large end of the material, thus ensuring the smooth conveying of the material in the combing channel. The limiting strip is adjusted laterally on the horizontal conveyor mechanism via an elongated hole on the adjusting bracket, thus adjusting the width of the combing channel to accommodate the conveying of various sizes of conical materials. The sliding strip can be made of nylon, a wear-resistant material with hygiene requirements. The second drive motor simultaneously drives two second bevel gears to rotate via its output shaft. These two second bevel gears mesh with their respective first bevel gears, driving the two belts synchronously via the front guide pulley, aligning the conveying channel with the horizontal conveyor belt's direction. Clamping plates constrain the distance between the two belts, preventing material slippage due to insufficient clamping force during conveying. The two clamping plates also have a horizontal distance adjustment structure and are fixed to the machine body using common methods to accommodate the conveying and placement requirements of different material sizes. Alternatively, in actual implementation, the synchronous transmission mechanism can also drive the belts by separately driving the two rear guide pulleys. Each second bevel gear engages with the output shaft of the second drive motor via a bushing and is secured with a fixing screw. This facilitates axial position adjustment of the second bevel gears, ensuring good meshing with the first bevel gears. Furthermore, each bushing engages with the output shaft of the second drive motor via a key, guaranteeing torque transmission. The first and second speed controllers control the rotational speeds of the first and second drive motors, respectively, thereby controlling the conveying speeds of the conveying and combing channels. The conveying speed of the conveying channel is equal to that of the upstream conveyor belt, preventing material accumulation within the channel. The conveying speed of the combing channel is higher than that of the conveying channel, preventing excessive material density and potential tipping. For example, in practical applications, the spacing between materials in the combing channel can be adjusted by the first and second speed controllers, ensuring that the minimum distance between adjacent materials is greater than the total length of the materials plus 5 mm, thus meeting the minimum spacing requirements for normal operation of the flipping process.

[0020] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1:

[0022] according to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, an automatic flipping conveyor device is installed between an upstream conveyor belt 26 and a downstream conveyor belt 27 for automatically flipping the conveyed conical material 25. It includes: a vertical conveying mechanism 2, consisting of two belts 6 on the same horizontal plane, with a conveying channel 7 formed between the two belts 6. The receiving end of the conveying channel 7 is located below the output end of the upstream conveyor belt 7; a straightening conveying mechanism 1, consisting of a horizontal conveyor belt 3 and a combing channel 4 arranged above the horizontal conveyor belt 3 along the conveying direction, with limiting strips 5 on both sides of the combing channel 4, each limiting strip 5 corresponding to the two sides of the conveying channel 7 away from the upstream conveyor belt; the working surface of the horizontal conveyor belt 3 is lower than the horizontal plane where the belts 6 are located; the horizontal conveyor belt 3 is equipped with a first drive motor 8, and the vertical conveying mechanism 2 is equipped with a second drive motor 9, which simultaneously drives the two belts 6 to rotate synchronously via a synchronous transmission mechanism; and a controller 10, electrically connected to the first drive motor 8 and the second drive motor 9.

[0023] Through the above settings, tapered materials are graded and sorted, and finally the materials 25 are transported in an orderly manner to the downstream conveyor belt 27 via the horizontal conveyor belt 3. With this automatic flipping conveyor, no manual intervention is required, and the flipping conveyor is greatly improved. By optimizing the conveying speed, the work efficiency can be greatly improved, and the material processing can reach a volume of 250-350 pieces per minute, far exceeding the level of manual operation. Specifically, the conveyor belt throws the scattered and discontinuous material 25 out of the output end. The material 25 falls into the conveyor channel 7 in a parabolic trajectory. Since the distance between the belts 6 on both sides of the conveyor channel 7 is between the diameter of the small end and the diameter of the large end of the material 25, after the material 25 falls into the conveyor channel 7, the small end hangs down naturally, while the large end is stuck on the upper part of the belt 6. It is conveyed by the two belts 6 in the conveyor channel 7 at a vertical angle with the small end facing down. At the end of the conveyor channel 7, when it encounters the horizontal conveyor belt 3, the bottom of the material 25 is blocked by the input end of the horizontal conveyor belt 3. At this time, the large end of the material 25 continues to be conveyed by the belt 6, so that the material 25 is tilted onto the horizontal conveyor belt 3 with the large end facing forward. Under the constraint of the limiting strips 5 on both sides of the combing channel 4, the angle will not change due to rolling. The distance between the two limiting strips 5 is slightly larger than the diameter of the large end of the material 25, thus ensuring the smooth conveying of the material 25 in the combing channel 4.

[0024] Example 2:

[0025] It also includes an adjustment bracket 14 for simultaneously fixing each of the limiting strips 5 to the machine body. The adjustment bracket 14 is arranged horizontally above the combing channel 4 and has an elongated hole perpendicular to each of the limiting strips 5. Each of the limiting strips 5 is fixed to the bottom of the adjustment bracket 14 by a bolt 13 passing through the elongated hole. Each of the limiting strips 5 has a sliding strip 15 on one side corresponding to the combing channel 4.

[0026] In the above configuration, the limiting strip 5 is adjusted laterally on the horizontal conveying mechanism through the elongated hole on the adjusting bracket 14, and completes the width adjustment function of the combing channel 4, thereby adapting to the conveying task of various sizes of conical materials 25. The sliding strip 15 can be made of nylon, a wear-resistant material with hygiene requirements.

[0027] Example 3:

[0028] The vertical conveying mechanism 2 further includes a pair of clamping plates 16 respectively disposed on both sides of the conveying channel 7. The two adjacent side walls of the two clamping plates 16 are arranged parallel to each other. The two belts 6 rotate around the corresponding clamping plates 16 through their respective pulley sets. The outer wall of the adjacent side of each clamping plate 16 is provided with a belt groove 28 corresponding to the belt 6. The pulley set of each belt 6 includes a front guide wheel 17 disposed on the clamping plate 16 near the upstream conveyor belt 26 and a rear guide wheel 18 disposed on the clamping plate 16 near the horizontal conveyor belt 3. The synchronous transmission mechanism consists of a first bevel gear 20 coaxially connected to the two front guide wheels 17 and two second bevel gears 21 coaxially arranged on the output shaft 22 of the second drive motor 9. The two second bevel gears 21 mesh with their respective first bevel gears 20 for transmission.

[0029] In the above configuration, the second drive motor 9 simultaneously drives two second bevel gears 21 to rotate via the output shaft 22. Each of the two second bevel gears 21 meshes with its own first bevel gear 20, thereby driving the two belts 6 synchronously via the front guide wheel 17, aligning the conveying channel 7 with the conveying direction of the horizontal conveyor belt 3. The clamping plate 16 constrains the distance between the two belts 6 and, under the constraint of the belt groove 28, achieves the conveying action, preventing material 25 from falling off due to insufficient clamping force on the belts 6 during conveying. The two clamping plates 16 also have corresponding horizontal distance adjustment structures and are fixed to the machine body in a common manner to accommodate the conveying requirements of conical materials of different specifications. Alternatively, in actual implementation, the synchronous transmission mechanism can also drive the belts 6 by driving the two rear guide wheels 18 separately.

[0030] Example 4:

[0031] The two second bevel gears 21 are nested on the output shaft 22 of the second drive motor 9 via a keyway bushing 29, and the bushing 29 is provided with a radially penetrating fixing screw 30 in the middle.

[0032] With the above configuration, each second bevel gear 21 is engaged with the output shaft 22 of the second drive motor 9 via a bushing 29. The bushing 29 is locked and fixed to the output shaft 22 by a fixing screw 30. This facilitates the adjustment of the axial position of the second bevel gear 21, making it easier to form a good meshing effect with the first bevel gear 20. In addition, the bushing 29 is engaged with the output shaft 22 of the second drive motor 9 via a key, ensuring the transmission of torque.

[0033] Example 5:

[0034] The controller 10 is equipped with a first speed regulator 23 and a second speed regulator 24 corresponding to the first drive motor 8 and the second drive motor 9, respectively, for adjusting the conveying speed of the conveying channel 7 and the combing channel 4.

[0035] In the above configuration, the first speed controller 23 and the second speed controller 24 control the rotational speeds of the first drive motor 8 and the second drive motor 9, respectively, thereby achieving the conveying speeds of the conveying channel 7 and the combing channel 4. The conveying speed of the conveying channel 7 is the same as the conveying speed of the upstream conveyor belt 26, thus preventing the accumulation of material 25 falling into the conveying channel 7. The conveying speed of the combing channel 4 is greater than that of the conveying channel 7, thus preventing the material 25 from being too densely packed in the combing channel 4 and causing it to tip over. For example, in practical applications, the spacing between the material 25 in the combing channel 4 can be adjusted by controlling the first speed controller 23 and the second speed controller 24, so that the minimum spacing between adjacent material 25 is greater than the total length of the material 25 plus 5 mm, thereby meeting the minimum spacing required for normal operation of the flipping process.

[0036] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
