Description

Technical Field

[0001] This invention relates to the field of material handling and loading / unloading equipment technology, and in particular to a ton container tilting and unloading device. Background Technology

[0002] IBCs (ton containers) are standardized liquid storage and transportation containers widely used in industries such as chemical, food, and pharmaceutical. They have advantages such as large capacity, stable structure, and ease of transportation and stacking. In actual production processes, it is often necessary to quickly and thoroughly unload the liquid materials in the IBCs. Therefore, IBC tipping and unloading devices have become key auxiliary equipment.

[0003] Currently, common ton container unloading methods mostly employ mechanical tipping mechanisms to flip the entire ton container to a certain angle (usually 180°), allowing the liquid inside to flow out from the outlet by gravity. However, in actual drainage, as the liquid continuously flows out, the gas volume inside the container increases and the pressure decreases. If there is no effective external gas replenishment channel, a negative pressure environment will quickly form inside the container. This negative pressure will significantly hinder the continued flow of liquid, and in severe cases, it may even lead to drainage interruption, affecting unloading efficiency and process continuity. To alleviate the above problems, patent publication number CN110194374B discloses an automatic tipping device for ton containers. This device applies up-and-down vibration to the ton container during the unloading process to break up local bubble accumulation or temporarily release blockages, thereby improving the drainage state. However, such methods can only achieve instantaneous disturbance and cannot establish a stable and continuous gas-liquid exchange channel inside the container. The gas pressure balance effect is limited, and the drainage speed is still constrained. In addition, the vibration method may cause fatigue damage to the ton container structure and is not suitable for shear-sensitive or easily foaming liquid materials. Summary of the Invention

[0004] In view of this, the present invention provides a ton container tilting and unloading device, which can solve the shortcomings of existing ton container tilting and unloading devices, such as poor drainage and low efficiency due to negative pressure formation inside the container during the liquid discharge process, and the limited effect of air pressure balance due to reliance on vibration disturbance, which may damage the ton container structure or is not suitable for sensitive liquid materials.

[0005] The technical implementation scheme of the present invention is as follows: a ton container tilting and unloading device includes a frame, a support frame rotatably mounted on the frame, a lifting frame slidably mounted on the support frame, a drive mechanism mounted on the frame, the drive mechanism being used to drive the support frame to rotate and the lifting frame to slide, a rotating ring rotatably mounted on both the support frame and the lifting frame, an eccentric disk eccentrically mounted inside the rotating ring, a rotating mechanism mounted on the support frame, the rotating mechanism being used to drive the rotating ring on one side to rotate, universal ball seats spaced apart on the eccentric disk on one side, a support plate for supporting the ton container being provided between the top of the universal ball seats, a spring connecting the support plate and the eccentric disk on one side, a positioning mechanism for positioning the ton container being provided on the eccentric disk on one side, an electric suction cup and an adjustment mechanism being installed on the eccentric disk on the other side, a discharge hopper slidably mounted on the adjustment mechanism, the adjustment mechanism being used to adjust the height of the discharge hopper, and a sealing mechanism for sealing the ton container being provided inside the discharge hopper.

[0006] More preferably, the drive mechanism includes a first motor and a first electric push rod. The first motor is mounted on the side of the frame, the output shaft of the first motor is connected to the support frame, the first electric push rod is mounted on the support frame, and the telescopic rod of the first electric push rod is connected to the lifting frame.

[0007] More preferably, the rotating mechanism includes a second motor, a gear, and a gear ring. The second motor is mounted on the support frame, and the output shaft of the second motor is connected to the gear. A gear ring is mounted on one side of the rotating ring, and the gear ring meshes with the gear.

[0008] More preferably, the positioning mechanism includes a lead screw motor, a sliding block, and a positioning rod. The lead screw motor is installed at intervals on one side of the eccentric disk, and the sliding block is slidably arranged at intervals on the other side of the eccentric disk. The sliding block is threadedly connected to the lead screw of the lead screw motor, and the positioning rod is connected to the sliding block.

[0009] More preferably, the adjusting mechanism includes a guide frame, a screw, and a sealing gasket. The guide frame is installed on the eccentric disc on the other side, the discharge hopper is slidably mounted on the guide frame, the screw is rotatably mounted on the guide frame, the screw is threadedly connected to the discharge hopper, and a sealing gasket is installed on the inner side of the discharge hopper.

[0010] More preferably, the sealing mechanism includes an inclined plate, a second electric push rod, and a baffle. An inclined plate is installed inside the discharge hopper, a second electric push rod is connected to the inclined plate, and a baffle is connected to the telescopic rod of the second electric push rod.

[0011] More preferably, it also includes a buffer pad, with a buffer pad installed on top of the support plate, the buffer pad being used to cushion the ton container.

[0012] More preferably, it also includes a support mechanism, which includes ball joints and hinges. Ball joints are installed at intervals on the support frame, the lifting frame and the eccentric plates on both sides, and hinges are rotatably installed between two adjacent ball joints.

[0013] Compared with the prior art, the present invention has the following advantages: 1. The present invention sets up an eccentric disk rotation mechanism driven by a second motor, so that the ton container performs eccentric rotation in an inverted state. The liquid inside the container forms a high-speed swirling flow under the combined action of centrifugal force and gravity, and establishes a stable low-pressure airflow channel in the center of the container cavity, thereby continuously balancing the air pressure inside and outside the container, completely eliminating the "air resistance" and "wall hanging" phenomenon caused by negative pressure, and achieving rapid and thorough emptying. It is especially suitable for sensitive liquid materials such as high viscosity or easy foaming.

[0014] 2. This invention uses a radial positioning mechanism driven by a screw motor, combined with a universal ball seat and a spring buffer system, to achieve automatic centering, flexible clamping, and multi-degree-of-freedom adaptive leveling of ton containers of different specifications. At the same time, the electric suction cup and the adjustable discharge hopper with a sealing gasket work together to ensure a tight connection at the liquid outlet and no leakage. The entire loading, unloading, flipping, unloading, and resetting process can be completed automatically, greatly improving the safety and efficiency of the operation.

[0015] 3. The present invention is equipped with a buffer pad to absorb the impact of placement and avoid damage to the bottom of the ton container; the support mechanism adopts a flexible multi-point support network composed of ball joints and hinges, which effectively disperses the load and prevents the eccentric disk from deforming while ensuring smooth eccentric rotation. The overall structure takes into account both rigidity and flexibility, enhancing the reliability and durability of the device in long-term operation. Attached Figure Description

[0032] See Figure 1 and Figure 2 As shown, the drive mechanism includes a first motor 401 and a first electric push rod 402; the first motor 401 is installed on the upper right side of the frame 1, and the output shaft of the first motor 401 is connected to the support frame 2; two first electric push rods 402 are symmetrically installed on the inner side of the support frame 2, and the telescopic rods of the two first electric push rods 402 are connected to the lifting frame 3.

[0033] See Figure 3 and Figure 4 As shown, the rotating mechanism includes a second motor 701, a gear 702, and a gear ring 703; the second motor 701 is installed on the front side of the inner support frame 2; the gear 702 is connected to the output shaft of the second motor 701, and the gear ring 703 is installed on the outer side of the rotating ring 5 on the lower side, and the gear ring 703 meshes with the gear 702.

[0034] See Figure 6 and Figure 7 As shown, the positioning mechanism includes a lead screw motor 1101, a sliding block 1102, and a positioning rod 1103; four lead screw motors 1101 are evenly spaced on the lower eccentric disk 6; four sliding blocks 1102 are evenly spaced on the lower eccentric disk 6, and the sliding blocks 1102 are threadedly connected to the lead screw of the lead screw motor 1101; the top of each of the four sliding blocks 1102 is connected to a positioning rod 1103.

[0035] See Figures 8-11As shown, the adjustment mechanism includes a guide frame 1301, a screw 1302, and a sealing gasket 1303; the guide frame 1301 is installed in the middle of the top of the eccentric disk 6 on the upper side; the discharge hopper 14 is slidably disposed on the guide frame 1301, and the screw 1302 is rotatably disposed on both the front and rear sides of the guide frame 1301, and the screw 1302 is threadedly connected to the discharge hopper 14; a sealing gasket 1303 is installed on the lower side inside the discharge hopper 14.

[0036] See Figures 9-11 As shown, the sealing mechanism includes an inclined plate 1501, a second electric push rod 1502, and a baffle 1503; two inclined plates 1501 are symmetrically installed on the upper side of the discharge hopper 14, and the inclined plates 1501 can guide the flow of liquid; the second electric push rod 1502 is connected between the two inclined plates 1501, and the baffle 1503 is connected to the telescopic rod of the second electric push rod 1502, and the baffle 1503 blocks the inner side of the discharge hopper 14.

[0037] In use, the ton container is first placed on the support plate 9. Then, the four lead screw motors 1101 in the positioning mechanism drive the corresponding sliding blocks 1102 to move synchronously towards the center in the radial direction, causing the positioning rod 1103 to press against the outer wall of the ton container, thereby achieving precise positioning and centering of the ton container in the horizontal plane. During this process, the support plate 9 achieves multi-degree-of-freedom fine adjustment through the universal ball seat 8, and the spring 10 deforms. In this way, the positioning and clamping of the ton container can be completed. Then, the first electric push rod 402 drives the lifting frame 3 to move downward, which drives the upper eccentric plate 6, electric suction cup 12, guide frame 1301 and discharge hopper 14 to descend synchronously. When the electric suction cup 12 contacts the top of the ton barrel, it generates negative pressure by powering on, which firmly adsorbs the top of the ton barrel and achieves a rigid connection. Then, the screw 1302 is twisted to rotate, so that the discharge hopper 14 moves precisely down along the guide frame 1301 until the sealing gasket 1303 on it tightly fits the liquid outlet of the ton barrel, forming a docking channel with good airtightness to prevent leakage during unloading. In this way, the top adsorption of the ton barrel and the docking of the liquid outlet can be completed. Then, the first motor 401 drives the support frame 2, together with the entire lifting frame 3 and the ton barrel, to rotate 180°, so that the ton barrel is flipped from an upright state to an inverted state. At this time, the liquid in the ton barrel begins to flow to the outlet under the action of gravity. After the flipping is completed, the second electric push rod 1502 drives the baffle 1503 to move, so that the baffle 1503 no longer blocks the inside of the discharge hopper 14, so that the liquid in the ton barrel is discharged from the outlet through the discharge hopper 14. At the same time, the second motor 701 rotates through the gear 702, so that the gear 702 drives the gear ring 703 and the rotating ring 5 to rotate, thereby driving the upper and lower eccentric disks 6 to rotate synchronously and eccentrically, and then driving the ton barrel to rotate eccentrically with the eccentric disks 6. This movement causes the residual liquid in the barrel to form a high-speed swirling flow under the combined action of centrifugal force and gravity, forming a stable low-pressure airflow channel in the center of the barrel cavity, effectively breaking the phenomenon of liquid "hanging on the wall" and "air resistance", and significantly improving the emptying efficiency. After the liquid in the ton container is drained, the second motor 701 drives the gear 702 to stop rotating, causing the rotating ring 5, eccentric disk 6, and ton container to stop rotating. Then, the second electric push rod 1502 drives the baffle 1503 to move and reset, so that the baffle 1503 blocks the inside of the discharge hopper 14 again. Then, the first motor 401 drives the support frame 2, together with the entire lifting frame 3 and the ton container, to rotate 180° in the opposite direction to reset, so that the ton container slowly returns to its original upright position. Next, the electric suction cup 12 is de-energized to release the top of the ton container. Then, the first electric push rod 402 drives the lifting frame 3 to rise, so that the discharge hopper 14 is separated from the liquid outlet of the ton container and the electric suction cup 12 is removed from the top of the ton container. Then, the lead screw motor 1101 drives the positioning rod 1103 to return to the initial position, releasing the constraint on the ton container. At the same time, the spring 10 returns to its original state and drives the support plate 9 to move and reset. Then, the empty ton container can be removed from the support plate 9.

[0038] See Figure 6 and Figure 7 As shown, it also includes a buffer pad 16; the top of the support plate 9 is equipped with a buffer pad 16, which is used to buffer the ton container.

[0039] By setting the buffer pad 16, the impact and vibration can be effectively absorbed during the placement of the ton container, preventing the bottom of the ton container from deforming, wearing or breaking due to rigid contact. At the same time, the buffer pad 16 can also enhance the friction between the ton container and the support plate 9, and improve stability.

[0040] See Figure 12 and Figure 13 As shown, it also includes a support mechanism, which includes a ball joint 17 and a hinge 18; ball joints 17 are installed at intervals on the bottom of the support frame 2, the bottom of the lifting frame 3, the bottom of the lower eccentric plate 6, and the top of the upper eccentric plate 6; a hinge 18 is rotatably installed between two adjacent ball joints 17.

[0041] By setting up a support mechanism, a stable support network with multiple flexible connections can be formed on the upper and lower eccentric discs 6, thereby providing support for the eccentric discs 6 and preventing them from denting after being squeezed by the ton barrel. Moreover, the combination of the ball joint 17 and the hinge 18 allows the support frame 2, the lifting frame 3, and the upper and lower eccentric discs 6 to make flexible angle adjustments and rotational movements at multiple contact points. This design can effectively adapt to the eccentric rotation of the eccentric discs 6.

Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
