Description

Technical Field

[0001] The utility model relates to the field of container equipment, in particular to a container overturning device suitable for a container track line. Background Art

[0002] The production floor of the open top container is a steel floor. When producing the open top container, the steel floor needs to be sprayed and dried. Previously, the container could not be turned 180 degrees before entering the container spraying process, and the steel floor could only be sprayed manually. Not only could automatic spraying equipment not be used, but the risk of pollution was increased. At the same time, the hot air in the drying room could not fully enter the interior of the box, resulting in the paint not being able to dry evenly and low drying efficiency.

[0003] In order to solve the above problems, the existing solution is to fix the two ends of the container with a large-scale flipping device, and realize the flipping of the container by synchronously lifting and rotating the two ends of the container. This solution requires a large area and cannot be used flexibly. The container needs to be transported to the location of the flipping device through corresponding auxiliary equipment and then flipped, and then the container is transported to the spraying and drying station. This process is cumbersome and time-consuming. Therefore, in order to optimize the flipping efficiency, there is an urgent need for a flipping device that can be applied to the container track line to directly flip the container on the track line, improve the flipping efficiency, and then improve the spraying and drying efficiency. Utility Model Content

[0004] The utility model aims to provide a container overturning device suitable for a container track line to solve the problems raised by the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a container turning device suitable for a container track line, comprising a plurality of parallel loose chains, each end of the chain being respectively equipped with a sprocket, and the sprocket is arranged at a high place above the track line; in an initial state, a part of the middle end of the chain falls on the ground and passes through the track line through a groove provided by the track line, forming a receiving slot for accommodating the container; after the container enters the receiving slot, the lifting and lowering of the container is achieved by controlling the sprockets at both ends of the same chain to rotate in opposite directions, and the turning of the container is achieved by controlling the sprockets at both ends of the same chain to rotate in the same direction.

[0006] Therefore, the utility model can use the grooves of the track line to automatically flip the container parked on the track line 180 degrees, reduce manual operations, and improve production efficiency; the accommodating groove formed by the loose chain is not only suitable for the flipping of different types of boxes, but also does not require the modification of the original equipment, and has good versatility; and the transmission mechanism of the chain sprocket is stable and reliable during the flipping process, which can ensure the quality of subsequent operations such as spraying and drying, and reduce the risk of pollution.

[0007] Preferably, the portion between the sprockets at both ends of the same chain is a middle section, and the distance between the two ends of the middle section is less than the width of the container. Thus, after the container is raised, the chain can clamp the container from both sides and the bottom of the container, so that when the container is turned over, there will be no slippage, and the container can be turned over efficiently.

[0008] Preferably, two sets of independent power devices are further included, and the sprockets at both ends of the same chain are connected to different power devices respectively, and the power devices control the sprockets to rotate around their own axes. Thus, the sprockets at both ends are free to turn by the independent power devices at both ends of the chain, thereby realizing a mechanism in which both ends of the chain rise and fall together or one rises and the other falls, thereby realizing the overturning of the entire container.

[0009] Preferably, it further comprises a frame, the frame spanning the track line, the power device is arranged on the frame and located at a high position above the track line, and the center of the sprocket is fixedly connected to the output end of the power device. Therefore, the utility model provides support for the sprocket and the power device above the track line through the frame, and provides a reserve space for the movement of the chain and the container.

[0010] Preferably, the power device includes a motor, a reducer and a transmission shaft, the motor and the reducer are connected in sequence, the reducer is fixed to the frame; the output end of the reducer is connected to the transmission shaft, the transmission shaft is connected to the frame through a bearing and a bearing seat, and the transmission shaft is coaxially fixed with the sprocket. Thus, through the cooperation between the motor, the reducer and the transmission shaft, power is applied to the sprocket, ensuring the accuracy and stability of the sprocket chain transmission and the container overturning process.

[0011] Preferably, when the sprockets at both ends of the same chain rotate outward at the same speed, the container is raised; when the sprockets at both ends of the same chain rotate inward at the same speed, the container is flipped; when the sprockets at both ends of the same chain rotate inward at the same speed, the container is lowered. Thus, the role of the rotation direction of the sprocket in the flipping process of the container is specifically explained: when the two sprockets rotate outward synchronously, the receiving slot and the container are raised to provide space for subsequent flipping; when one sprocket rotates outward and the other rotates inward, the chain moves unidirectionally, thereby driving the container to flip; when the two sprockets rotate inward synchronously, the flipped container is lowered so that it can continue to move along the track line and enter the next workstation.

[0012] Preferably, the chain is a double-row chain, thereby increasing the chain strength. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] According to the problems mentioned in the background technology, the utility model aims to provide a set of container turning equipment, which turns the container 3 on the track line 180 degrees before entering the container 3 spraying process. Therefore, the following embodiment discloses a container turning equipment suitable for the container track line. The equipment is installed on the container 3 production line without affecting the continued movement of the container 3 on the track. For the specific structure, please refer to Figures 1 to 7 .

[0021] See also Figures 1 to 3 The turning device includes a plurality of parallel loose chains 1, two sets of independent power devices 5 and a frame 4. The frame 4 spans the track line. The power device 5 is arranged on the frame 4 and is located high above the track line. Both ends of each chain 1 are connected to the two sets of power devices 5 through sprockets 2.

[0022] The power device 5 includes a motor 51, a reducer 52 and a transmission shaft 53. The motor 51 and the reducer 52 are connected in sequence, and the reducer 52 is fixed to the frame 4. The output end of the reducer 52 is connected to the transmission shaft 53, and the transmission shaft 53 is connected to the frame 4 through a bearing and a bearing seat. The transmission shaft 53 is coaxially fixed with a sprocket 2, that is, the center of the sprocket 2 is fixedly connected to the output end of the power device 5.

[0023] Each chain 1 has two ends respectively matched with a sprocket 2 connected to a different power device 5. In this embodiment, there are two chains 1, corresponding to the front half and the rear half of the length of the container 3, that is, each group of power devices 5 is connected to two chains 1, and the transmission shafts of the two groups of power devices 5 are also parallel to each other. In order to ensure that the strength of the chain 1 is sufficient to flip the container 3, each chain 1 is a double-row chain. The utility model can also use three chains 1. On the basis of two chains 1, one chain 1 is added so that it is located between the two chains 1.

[0024] Since the sprockets 2 at both ends of the same chain 1 are respectively connected to different power devices 5, the sprocket 2 can be controlled by the power device 5 to rotate around its own axis, which can drive the two ends of the chain 1 to rise and fall at the same time or one rises and the other falls, providing a power basis for the subsequent flipping of the entire container 3.

[0025] Since the sprocket 2 and the transmission shaft 53 are both located above the track line, the loose chain 1 has a naturally drooping portion. Here, the naturally drooping portion located between the sprockets 2 at both ends of the same chain 1 is called the middle section. Figure 3 In the initial state, the middle end of the chain 1, i.e., the middle section, partially falls on the ground and passes through the track line through the groove provided by the track line (the track line and the groove thereon are not shown in the figure). Specifically: the middle section includes a first section 11, a second section 12, and a third section 13 connected in sequence, wherein the second section 12 falls on the ground and passes through the track line through the groove provided by the track line, the head of the first section 11 and the head of the third section 13 start from the corresponding sprocket 2 respectively, and the tail of the first section 11 and the tail of the third section 13 are respectively connected to the two ends of the second section 12, thereby forming a receiving groove 14 for accommodating the container 3 between the first section 11, the second section 12, and the third section 13.

[0026] In order to prevent the container 3 in the receiving slot 14 from slipping when turning over, the distance between the two ends of the middle section should be smaller than the width of the container 3, that is, the distance between the head of the first section 11 and the head of the third section 13 is smaller than the width of the container 3, and the distance between the tail of the first section 11 and the tail of the third section 13 is larger than the width of the container 3, that is, the length of the second section 12 should be at least longer than the width of the container 3, so as to ensure that the container 3 can enter the receiving slot 14 when traveling along the track line. Therefore, after the container 3 is raised, the chain 1 can clamp the container 3 from both sides and the bottom of the container 3, so that when the container 3 is turned over, there will be no slipping, and the container 3 can be turned over efficiently.

[0027] The utility model provides support for the sprocket 2 and the power device 5 above the track line through the frame 4, and provides a reserve space for the movement of the chain 1 and the container 3. After the container 3 enters the receiving slot 14, the lifting of the container 3 is achieved by controlling the sprockets 2 at both ends of the same chain 1 to rotate in opposite directions, and the flipping of the container 3 is achieved by controlling the sprockets 2 at both ends of the same chain 1 to rotate in the same direction. Figure 4 for Figure 1 The main view, Figures 5 to 7 by Figure 4 Based on this view, the complete turning process of the container 3 after entering the receiving slot 14 can be shown. The following specifically describes the role of the rotation direction of the sprocket 2 in the turning process of the container 3, where "outside" refers to the opposite sides of the sprockets 2 at both ends of the same chain 1, and "inside" refers to the opposite sides of the sprockets 2 at both ends of the same chain 1:

[0028] When the sprockets 2 at both ends of the same chain 1 rotate outward at the same speed at the same time (the two sprockets 2 rotate in opposite directions at this time), the receiving groove 14 and the container 3 rise to provide space for subsequent turning;

[0029] When the sprockets 2 at both ends of the same chain 1 rotate at the same speed, one to the inside and the other to the outside (at this time, the two sprockets 2 rotate in the same direction), the unidirectional movement of the chain 1 drives the container 3 to flip;

[0030] When the sprockets 2 at both ends of the same chain 1 rotate inward at the same speed (the two sprockets 2 rotate in opposite directions at this time), the container 3 is lowered. After the container 3 falls onto the track, the chain 1 enters the groove of the track line to release the container 3. The container 3 can continue to move along the track line and enter the next workstation.

[0031] Figure 4 The initial state of the chain 1 and the container 3 just entering the receiving slot 14 are shown; Figure 5 The container 3 is shown after being raised. Figure 6 The container 3 is shown flipped 90 degrees. Figure 7Container 3 is shown turned 180 degrees and lowered onto the track; Figures 4 to 7 The complete turning process of the container 3 is shown. In the figure, the right power device 5 controls the corresponding sprocket 2 to rotate outward, and the left power device 5 controls the corresponding sprocket 2 to rotate inward, thereby realizing a counterclockwise turning of the container 3 by 180 degrees.

[0032] Based on the above structure, this embodiment can utilize the grooves of the track line to automatically flip the container 3 that stays on the track line 180 degrees, thereby reducing manual operations and improving production efficiency; the accommodating groove 14 formed by the loose chain 1 is not only suitable for flipping different types of boxes, but also does not require modification of the original equipment, and has good versatility; power is applied to the sprocket 2; and through the cooperation between the motor 51, the reducer 52 and the transmission shaft 53, the transmission mechanism of the chain 1 and the sprocket 2 is stable and reliable during the flipping process, ensuring the accuracy and stability of the sprocket chain transmission and the container flipping process, thereby ensuring the quality of subsequent operations such as spraying and drying, and reducing the risk of pollution.

[0033] In summary, the utility model is suitable for various production lines with steel floors and open-top containers, and has a wide range of application prospects. At the same time, the equipment has good versatility and maintainability, and can meet the needs of different customers.
