Description

Technical Field

[0001] This utility model belongs to the field of rapeseed oil packaging technology, specifically referring to a rapeseed oil barrel packing machine. Background Technology

[0002] After rapeseed oil is filled, the drums need to be packed into cardboard boxes for packaging, with a standard packaging size of four drums per box. Currently, this packaging process is mainly completed by automated robotic arms. The specific operation process is as follows: first, the empty cardboard box is accurately positioned at the packing station, and then the robotic arm uses a special gripper to grab four drums of oil at once, smoothly transfers them, and accurately places them into the cardboard box.

[0003] However, this automated packing method has some pressing issues. As a highly integrated automated device, the robotic arm requires regular professional maintenance and precision upkeep, including but not limited to joint lubrication, sensor calibration, and gripper replacement. These maintenance tasks not only require skilled technicians but also incur considerable maintenance costs and downtime. Furthermore, the core components of the robotic arm have a limited lifespan, leading to high replacement costs. In the current manufacturing context emphasizing cost reduction and efficiency improvement, this high-investment, high-maintenance automation solution contradicts the factory's goal of maximizing economic benefits and hinders the company's strategic pursuit of continuously improving production efficiency and market competitiveness. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a rapeseed oil drum packing machine, which at least partially solves the above problems.

[0005] The technical solution adopted by this utility model is as follows: This utility model proposes a rapeseed oil drum packing machine, which includes a fixed frame that is inclined perpendicular to the oil drum conveying direction;

[0006] A tray, the side of which is hinged to a fixed frame, has several turntables rotatably mounted on its upper wall, and several ball bearings rotatably mounted on the turntables;

[0007] A flexible tie rod connects the tray and the side wall of the fixed frame;

[0008] A limiting device for supporting or releasing a tray includes a supporting cone and a locking cone. The supporting cone is slidably mounted in a fixed frame via a return spring to support the tray. The locking cone is slidably mounted on one side of the supporting cone and elastically engages with the supporting cone to limit the movement of the supporting cone.

[0009] Furthermore, the side wall of the locking cone rod is provided with a telescopic spring rod, and a trapezoidal boss is provided between the supporting cone rod and the locking cone rod. The trapezoidal boss slides and fits against the side wall of the supporting cone rod, and the side wall of the supporting cone rod is provided with a locking groove. The side of the locking groove is adapted to the trapezoidal boss and the telescopic spring rod.

[0010] Furthermore, the outer end of the locking cone rod is connected to a telescopic cylinder, which is fixed to the side wall of the fixed frame. A position sensor is provided below the telescopic cylinder, which is used to detect the position of the cardboard box used to fill the oil drum.

[0011] Furthermore, the inner end of the support cone is provided with a bevel angle so as to convert the weight of the oil drum on the tray into a horizontal thrust.

[0012] Furthermore, a first baffle is provided on the upper end of the side wall of the fixed frame, and a second baffle is provided vertically at one end of the first baffle.

[0013] Furthermore, the lower end of the first baffle is provided with a limiting plate for limiting the rotation limit of the pallet.

[0014] Furthermore, the rapeseed oil drum packing machine proposed in this utility model also includes a horizontal conveying rail and an inclined conveying rail. The horizontal conveying rail is located on the material receiving side of the fixed frame and is used to transport the oil drums. The inclined conveying rail is located at the lower end of the horizontal conveying rail and is used to transport the cardboard boxes filled with the oil drums.

[0015] Furthermore, the tilt angle of the inclined conveyor rail is adapted to the tilt angle of the fixed frame.

[0016] The beneficial effects of this utility model are as follows: The inclined fixed frame, together with the turntable and ball bearings on the tray, can automatically position the oil drums and make them closely arranged. When the number of oil drums reaches the set value, the tray will open the limit device under the gravity of the oil drums, so that the oil drums on the tray will automatically fall into the carton below. The structure is simple and efficient, without the need for high-precision automated equipment, which is conducive to daily maintenance and reduces production costs. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0027] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] like Figures 1-2As shown in the figure, the rapeseed oil drum packing machine proposed in this embodiment includes a horizontal conveyor rail 1, an inclined conveyor rail 2, a fixed frame 4, a tray 5, and a limiting device. The horizontal conveyor rail 1 is used to transport oil drums. The fixed frame 4 is located on the unloading side of the horizontal conveyor rail 1 and is inclined, with its inclination direction perpendicular to the direction of oil drum conveying. The side of the tray 5 is hinged in the fixed frame 4. When the upper wall of the tray 5 coincides with the upper wall of the fixed frame 4, the tray 5 also presents the same inclined shape as the fixed frame 4. When the oil drum falls onto the tray 5, the oil drum will also tilt and eventually slide down automatically to the lowest point of the tray 5 under the action of gravity. The limiting device is located in the side wall of the fixed frame 4 and is used to support or release the tray. The tray 5 and the inclined conveyor rail 2 are located at the lower end of the horizontal conveyor rail 1 and are used to transport cartons filled with oil drums. The inclination angle of the inclined conveyor rail 2 is adapted to the inclination angle of the fixed frame 4 so that the opening direction of the carton is adapted to the material feeding direction of the oil drum. When the number of oil drums reaches the set value, the limiting device opens, causing the tray 5 to rotate and the oil drums on the tray 5 to fall into the carton. When the number of oil drums does not reach the set value, the limiting device keeps the tray 5 in the receiving state to prevent the oil drums from falling when they are not full. When the oil drums fall completely, in order to reset the tray 5 to the initial receiving position, an elastic pull rod 6 is connected between the tray 5 and the side wall of the fixed frame 4. The elastic pull rod 6 always pulls the tray 5 towards the fixed frame 4.

[0029] In some embodiments, such as Figure 3 As shown, in order to make the oil drums on the tray 5 slide more smoothly and to allow the oil drums to be arranged in sequence, the size of the tray 5 is adapted to the inner cavity size of the carton, and the upper wall of the tray 5 is provided with several turntables 9, and several ball bearings 10 are rotatably mounted on the turntables 9. When the oil drum slides onto the tray 5, under the action of gravity, and with the action of the ball bearings 10 and the turntables 9, it slides down to the lowest point it can reach, until it is in contact with the side wall of the fixed frame 4 or the side wall of the previous oil drum, and is pushed by the next oil drum to an orderly arrangement. The ball bearings 10 and the turntables 9 can reduce the friction on the bottom of the oil drum, so that the oil drums can be arranged in an orderly manner by gravity when tilted.

[0030] In some embodiments, such as Figures 4-5 As shown, the limiting device includes a supporting cone rod 13 and a locking cone rod 14. The supporting cone rod 13 is slidably disposed in the fixed frame 4 via a return spring 16. The return spring 16 always pushes the supporting cone rod 13 toward the fixed frame 4 to support the tray 5. The locking cone rod 14 is slidably disposed on one side of the supporting cone rod 13 and elastically engages with the supporting cone rod 13. The locking cone rod 14 is used to limit the movement of the supporting cone rod 13, such as... Figures 6-7As shown, the support cone rod 13 has a bevel at one end near the tray 5 to determine the number of oil drums on the tray 5. When the number of oil drums on the tray 5 reaches the set value, the weight of the oil drums will be decomposed into horizontal and vertical components under the action of the bevel. When the horizontal component is greater than the resistance of the return spring 16, the support cone rod 13 has the condition to retract inward. However, the support cone rod 13 is still restricted by the locking cone rod 14 and cannot move. Only when the number of oil drums on the tray 5 meets the requirements and the carton on the inclined conveyor rail 2 reaches the filling position can the locking cone rod 14 be opened so that the oil drums can fall accurately into the carton and prevent the oil drums from falling prematurely before the carton is in place.

[0031] In some embodiments, the outer end of the locking cone rod 14 is connected to a telescopic cylinder 8, the telescopic cylinder 8 is fixed to the side wall of the fixed frame 4, and a position sensor 3 is provided below the telescopic cylinder 8. The position sensor 3 is used to detect the position of the carton for filling the oil drum, and the detection signal of the position sensor 3 is electrically connected to the telescopic cylinder 8.

[0032] In some embodiments, such as Figures 4-5As shown, the side wall of the locking cone rod 14 is provided with a telescopic spring rod 15, and a trapezoidal boss 17 is provided between the supporting cone rod 13 and the locking cone rod 14. The trapezoidal boss 17 slides against the side wall of the supporting cone rod 13. The side wall of the supporting cone rod 13 is provided with a locking groove 18, and the side of the locking groove 18 is adapted to the trapezoidal boss 17 and the telescopic spring rod 15, that is, the side of the locking groove 18 and the side of the trapezoidal boss 17 can be aligned and coincident, and the locking groove 18 can be engaged with the telescopic spring rod 15. The ends of 5 are engaged, and the ends of the telescopic spring rod 15 can extend and retract through the internal elastic element. When the locking cone rod 14 is driven to retract by the telescopic cylinder 8, the telescopic spring rod 15 moves synchronously along the length direction of the locking cone rod 14. During the movement, the head of the telescopic spring rod 15 exits from the locking groove 18 and slides and retracts along the side wall of the trapezoidal boss 17 until it slides to the other side of the trapezoidal boss 17 and waits. At this time, the supporting cone rod 1 Under the pressure of the tray 5, the support cone rod 13 can overcome the resistance of the return spring 16 to retract, so as to release the oil drum on the tray 5. When the support cone rod 13 retracts, the locking groove 18 moves synchronously to the other side of the trapezoidal boss 17, and the head of the telescopic spring rod 15 will once again embed into the locking groove 18, locking the support cone rod 13 again. After the tray 5 is unloaded, because the support cone rod 13 is locked, the elastic pull rod 6 can pull the tray 5 back to the initial receiving position. The support cone rod 13 will not hinder the resetting of the tray 5. After the carton is filled with oil drums, it moves with the inclined conveyor rail 2. The signal of the position sensor 3 changes and controls the telescopic cylinder 8 to extend, so that the locking cone rod 14 extends. The locking cone rod 14 separates from the support cone rod 13 again. Under the action of the return spring 16, the support cone rod 13 retracts to the lower wall of the tray 5 again, and is once again engaged and fixed with the telescopic spring rod 15 through the locking groove 18, so as to repeat the next round of receiving operation.

[0033] In some embodiments, such as Figure 3 and Figure 6 As shown, the upper side wall of the fixed frame 4 is provided with a first baffle 11, and a second baffle 12 is provided vertically at one end of the first baffle 11. The lower end of the first baffle 11 is provided with a limiting plate 7 for limiting the rotation limit of the tray 5. The limiting plate 7 is set perpendicular to the inclined conveyor rail 2. The first baffle 11 is located on the inclined side of the fixed frame 4. The first baffle 11 and the second baffle 12 are used to limit and support the oil drum. The limiting plate 7 allows the oil drum to slide down at an angle perpendicular to the inclined conveyor rail 2 so as to better fill the oil drum.

[0034] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0035] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
