Description

Technical Field

[0001] This application relates to the field of container manufacturing technology, and in particular to a container positioning device. Background Technology

[0002] The assembly of wooden flooring for shipping containers is a crucial step in container manufacturing. As the core base layer for carrying cargo, the installation accuracy of the wooden flooring directly affects the stability of the container when carrying loads. In automated container production, to ensure the continuity and efficiency of the assembly process, the industry commonly uses belt conveyors to transfer containers from the pre-processing station to the wooden flooring installation station.

[0003] In existing technologies, the positioning of containers on belt conveyors mainly relies on two positioning methods: one is manual positioning, where the operator observes the relative position of the container's edge with the preset baseline of the installation station and manually controls the belt conveyor to stop the container at the predetermined installation position; the other is simple mechanical block positioning, where metal blocks are fixedly installed at the corresponding positions of the workstations. When the container moves with the belt to the wood flooring installation station, the container will come into contact with the metal block, and the rigid blocking force of the block will force the container to stop, thus completing the positioning operation.

[0004] Regarding the aforementioned technologies, the container itself is quite heavy. Even if the operator can stop the belt conveyor in time or the container receives rigid resistance from the metal block, the container will still move a certain distance due to inertia. Utility Model Content

[0005] In order to improve the positioning accuracy of containers on the conveying mechanism, this application provides a container positioning device.

[0006] The container positioning device provided in this application adopts the following technical solution: A container positioning device includes a conveying mechanism for placing a container and a positioning mechanism disposed on one side of the conveying mechanism for limiting the container. The positioning mechanism includes a fixed base, a push cylinder disposed on the fixed base, an extension plate connected to the piston rod of the push cylinder, and a positioning rotating plate rotatably disposed on the extension plate for blocking the container.

[0007] By adopting the above technical solution, when the container moves to the preset work position with the conveying mechanism, the cylinder drives the extension plate to extend, so that the positioning plate is located on the container's travel path. When the container contacts the positioning plate, the positioning plate can buffer the inertial impact force of the container by rotating, and reset the container by its own weight to complete the positioning of the container, thereby improving the positioning accuracy of the container.

[0008] Optionally, the positioning plate is provided with a rotating column, and the extension plate is provided with an installation groove corresponding to the rotating column and for the rotating column to be rotatably installed.

[0009] By adopting the above technical solution, the cooperation between the rotating column and the mounting groove provides a stable rotation fulcrum for the positioning plate, ensuring that the positioning plate can rotate smoothly around the fixed axis when it comes into contact with the container, bounces, and ensures a stable buffering effect. At the same time, it reduces the wear of the positioning plate and the extension plate and extends the service life of the components.

[0010] Optionally, a reset torsion spring is installed around the rotating column, with one end of the reset torsion spring abutting against the inner wall of the mounting groove, and the other end of the reset torsion spring extending outside the mounting groove to abut against the positioning rotating plate.

[0011] By adopting the above technical solution, when the positioning plate is not in contact with the container, the reset torsion spring deforms and accumulates elastic potential energy; when the positioning plate is squeezed and rotated by the container, the reset torsion spring releases potential energy to drive the positioning plate to rotate, which better alleviates the inertial impact force brought by the container. Then, the positioning plate relies on its own gravity to recompress the torsion spring to form a reset, thereby improving the automation level and working efficiency of the device.

[0012] Optionally, the extension plate is provided with an inclined block that abuts against the bottom of the positioning rotating plate, and the positioning rotating plate forms an inclined angle with the extension plate through the inclined block for the positioning rotating plate to rotate.

[0013] By adopting the above technical solution, the tilting block makes the positioning rotating plate form a preset tilt angle with the extension plate in the initial state. This angle can guide the direction of force when the container contacts the positioning rotating plate, making the positioning rotating plate easier to rotate around the rotating column and reducing the rigid impact at the initial contact.

[0014] Optionally, the fixed base is provided with a guide block between the push cylinder and the extension plate, and the guide block has a guide groove that slides and engages with the extension plate.

[0015] By adopting the above technical solution, the cooperation between the guide block and the guide groove can limit the sliding trajectory of the extension plate, ensure that the extension plate moves smoothly along a straight line under the drive of the push cylinder, reduce the probability of the extension plate deviating, and ensure that the positioning plate can accurately block the container; at the same time, the guide groove can also share the lateral force on the extension plate, reduce the bending stress of the piston rod of the push cylinder, and extend the service life of the cylinder.

[0016] Optionally, the guide block is provided with a guide seat for axially limiting the piston rod, and the guide seat has a guide through hole for the piston rod to pass through.

[0017] By adopting the above technical solution, the guide seat and guide through hole can axially limit the piston rod of the push cylinder, ensuring that the piston rod can stably drive the extension plate along the axial direction, further improving the accuracy and stability of the extension plate sliding, and ensuring the blocking position accuracy of the positioning plate.

[0018] Optionally, the positioning plate includes a positioning plate rotatably mounted on the extension plate and a telescopic plate for blocking containers and slidably mounted on the positioning plate. The positioning plate has a sliding groove for the telescopic plate to slide, and the positioning plate is provided with a locking structure for locking the telescopic plate.

[0019] By adopting the above technical solution, the telescopic plate can slide and adjust its length along the sliding groove of the positioning plate, so that the overall blocking height of the positioning plate can be adapted to containers of different height specifications; the locking structure can lock the adjusted position of the telescopic plate, ensuring that the telescopic plate will not slide relative to the positioning plate during the blocking process, and ensuring a stable blocking effect.

[0020] Optionally, the locking structure includes a locking block disposed on the side wall of the telescopic plate, a compression spring connected to the locking block, and a locking housing disposed on the telescopic plate and for the compression spring to be arranged. The positioning plate has a sliding groove for the telescopic plate to slide. The inner wall of the sliding groove has multiple sets of locking grooves that are locked in place with the locking block. The locking housing has a storage groove for the compression spring and the locking block to be arranged.

[0021] By adopting the above technical solution, when adjusting the length of the telescopic plate, the locking block is compressed by the inner wall of the sliding groove, compresses the spring, and retracts into the receiving groove, which facilitates the smooth sliding of the telescopic plate. When the telescopic plate moves to the target position, the locking block pops out under the action of the compression spring and embeds into the corresponding locking groove, realizing the rapid locking of the telescopic plate and the positioning plate. The setting of multiple sets of locking grooves can provide multiple length adjustment levels, further improving the adaptability of the positioning plate to containers of different specifications.

[0022] Optionally, the telescopic plate has a fixing groove for sliding installation of the locking housing, and the telescopic plate is provided with an unlocking structure for unlocking the locking block from the locked state. The unlocking structure includes a bearing seat disposed on the side of the locking housing away from the locking block, an unlocking screw rotatably mounted on the bearing seat and used to pull the locking housing, and a threaded through hole opened on the side wall of the telescopic plate and threadedly engaged with the unlocking screw.

[0023] By adopting the above technical solution, when unlocking is required, turning the handle drives the unlocking screw to rotate, and the threaded engagement pulls the locking housing, causing the locking block to disengage from the locking groove, thereby adjusting the length of the telescopic plate; the bearing seat provides stable support for the unlocking screw, ensuring that the locking housing will not rotate with the unlocking screw, thus improving the convenience of telescopic adjustment.

[0024] Optionally, the end of the unlocking screw away from the bearing seat is provided with a rotating handle, and the side wall of the positioning plate is provided with a sliding groove for the rotating handle to slide.

[0025] By adopting the above technical solution, the sliding groove provides sliding space for the rotating handle, avoiding interference between the handle and the positioning plate when the handle moves with the telescopic plate.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. By rotating the positioning plate on the extension plate in conjunction with the push cylinder, a flexible barrier is formed to buffer the inertial impact force of the container, reduce inertial slippage, improve the positioning accuracy of the container, and the positioning plate can automatically reset according to its own gravity, thus improving the automation level of the device. 2. The multi-position locking structure of the telescopic plate allows the positioning plate to be adapted to containers of different sizes, while the simplified design of the unlocking structure saves the time required for unlocking operations, significantly improving the versatility and ease of use of the device; 3. Auxiliary structures such as guide blocks and reset torsion springs optimize device performance in terms of sliding stability and automatic reset, ensuring a smooth and efficient positioning process and adapting to the continuous operation requirements of automated container production.

[0034] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0035] This application discloses a container positioning device.

[0036] Reference Figure 1 The container positioning device includes a conveying mechanism 1 for placing containers and a positioning mechanism 2 disposed on one side of the conveying mechanism 1 for limiting the container. The conveying mechanism 1 is a conventional belt conveyor.

[0037] Reference Figure 2 and Figure 4 The positioning mechanism 2 includes a fixed base 21, a push cylinder 22 mounted on the fixed base 21, an extension plate 23 connected to the piston rod of the push cylinder 22, and a positioning rotating plate 24 rotatably mounted on the extension plate 23 for blocking the container. The push cylinder 22 is a conventional piston cylinder, and a fixing clamp 221 is fixedly mounted on the end of its piston rod. The extension plate 23 is fixedly connected to the fixing clamp 221 by welding, thereby fixing the push cylinder 22 and the extension plate 23.

[0038] Reference Figure 3 Both the extension plate 23 and the positioning rotating plate 24 are rectangular plates. The positioning rotating plate 24 has a rotating column 241 rotatably mounted to the extension plate 23 on the side near the extension plate 23. The extension plate 23 has mounting grooves 231 corresponding to the two ends of the rotating column 241. The cooperation between the rotating column 241 and the mounting grooves 231 provides a stable rotation fulcrum for the positioning rotating plate 24, ensuring that the positioning rotating plate 24 can rotate smoothly around the axis of the rotating column 241 when it contacts the container. When the container contacts the positioning rotating plate 24, the positioning rotating plate 24 can buffer the inertial impact force of the container through rotation and reset the container's position by its own weight, improving the positioning accuracy of the container. The positioning rotating plate 24 is made of lead material, utilizing the high density of lead to achieve gravity reset.

[0039] The extension plate 23 has an inclined block 232 that abuts against the bottom of the positioning rotating plate 24. The cross-section of the inclined block 232 is a trapezoidal column with a right-angled trapezoidal shape, and the inclined surface of the inclined block 232 that abuts against the positioning rotating plate 24 is the inclined surface of the trapezoidal column. The positioning rotating plate 24 forms an inclined angle with the extension plate 23 through the inclined block 232 for the rotation of the positioning rotating plate 24. This inclined angle can guide the direction of force when the container contacts the positioning rotating plate 24, making it easier for the positioning rotating plate 24 to rotate around the rotating column 241 and reducing the rigid impact at the initial contact.

[0040] Reference Figure 4 The fixed base 21 has a guide block 211 between the push cylinder 22 and the extension plate 23. The guide block 211 has a guide groove 212 that slides with the extension plate 23. The length of the guide groove 212 is greater than the displacement of the piston rod in linear motion. The inner wall of the guide groove 212 abuts against the side wall of the extension plate 23 to ensure that the extension plate 23 moves smoothly in a straight line under the drive of the push cylinder 22, reducing the probability of the extension plate 23 deviating.

[0041] The guide block 211 is equipped with a guide seat 213 for axially limiting the piston rod. The guide seat 213 has a guide through hole 2131 through which the piston rod passes. The guide seat 213 is located at one end of the guide groove 212 near the push cylinder 22. The guide seat 213 and the guide through hole 2131 can axially limit the piston rod of the push cylinder 22, ensuring that the piston rod can stably drive the extension plate 23 along the axial direction.

[0042] Reference Figure 3 A reset torsion spring 242 is mounted around both ends of the rotating column 241. One end of the reset torsion spring 242 abuts against the inner wall of the mounting groove 231, and the other end extends to the outside of the mounting groove 231 and abuts against the positioning rotating plate 24. The contact surface between the positioning rotating plate 24 and the reset torsion spring 242 is the plate surface of the positioning rotating plate 24 facing the extension plate 23.

[0043] When the positioning plate 24 is not in contact with the container, the reset torsion spring 242 deforms and accumulates elastic potential energy. When the positioning plate 24 is squeezed and rotated by the container, the reset torsion spring 242 releases potential energy to drive the positioning plate 24 to rotate, which better alleviates the inertial impact force brought by the container. Then, the positioning plate 24 recompresses the torsion spring under its own gravity to return to its original position.

[0044] Reference Figure 5 In other embodiments, the positioning plate 24 includes a positioning plate 3 rotatably mounted on the extension plate 23 and a telescopic plate 4 slidably mounted on the positioning plate 3. The positioning plate 3 has a sliding groove 31 for the telescopic plate 4 to slide, and the telescopic plate 4 is provided with a locking structure. The telescopic plate 4 can slide along the sliding groove 31 of the positioning plate 3 to adjust its length, so that the overall blocking height of the positioning plate 24 can be adapted to containers of different widths.

[0045] The locking structure includes a locking housing 41, a compression spring 42, and a locking block 43. The locking housing 41 has a storage groove 411 for arranging the compression spring 42 and the locking block 43, and the telescopic plate 4 has a fixing groove 44 for sliding installation of the housing. One end of the compression spring 42 is fixedly connected to the inner wall of the locking housing 41, and the other end is fixed to the locking block 43. The locking block 43 has a guide slope 431 facing the opening of the sliding groove 31. When adjusting the length of the telescopic plate 4, the locking block 43 is compressed by the inner wall of the sliding groove 31, compressing the compression spring 42 and retracting into the storage groove 411. When the telescopic plate 4 moves to the target position, the locking block 43 pops out under the action of the compression spring 42 and embeds into the corresponding locking groove 32, achieving rapid locking between the telescopic plate 4 and the positioning plate 3. The multiple sets of locking grooves 32 provide multiple length adjustment levels, further improving the adaptability of the positioning plate 24 to containers of different specifications.

[0046] Reference Figure 6 The telescopic plate 4 is provided with an unlocking structure for unlocking the locking block 43 from its locked state. The unlocking structure includes a bearing seat 45, an unlocking screw 46, and a threaded through hole 47. The bearing seat 45 is installed on the side of the locking housing 41 away from the opening of the fixing groove 44. One end of the unlocking screw 46 is rotatably mounted to the bearing seat 45, and the other end extends through the threaded through hole 47 to the outside of the telescopic plate 4. The fixing groove 44 communicates with the threaded through hole 47, and the length of the fixing groove 44 is greater than the length of the locking housing 41. Rotating the unlocking screw 46 can drive the locking housing 41 to slide within the fixing groove 44, thereby unlocking and fixing the locking block 43. The other end of the unlocking screw 46 has a rotating handle 461, saving the operator the driving force applied to the unlocking screw 46. The side wall of the positioning plate 3 has a sliding groove 33 for the rotating handle 461 to slide, providing sliding space for the rotating handle 461 to slide with the telescopic plate 4.

[0047] The implementation principle of the container positioning device in this application embodiment is as follows: During the wood flooring assembly process, the conveyor mechanism 1 is activated to move the container to a preset workstation. Then, the conveyor mechanism 1 is shut down, and the positioning mechanism 2 is activated. The cylinder 22 pushes the extension plate 23, so that the positioning rotating plate 24 on the extension plate 23 is positioned on the travel path of the container. When the container contacts the positioning rotating plate 24, the positioning rotating plate 24, under the action of the tilting block 232 and the return torsion spring 242, rotates around the rotating column 241 to buffer the inertial impact force of the container. The positioning rotating plate 24 returns to its original position by its own gravity, thus completing the positioning of the container.

[0048] When assembling wooden flooring on containers of different specifications, the length of the positioning plate 24 can be adjusted by adjusting the telescopic plate 4. Rotating the unlocking screw 46 releases the locking block 43, adjusting the length of the telescopic plate 4 inserted into the positioning plate 3. As the telescopic plate 4 slides within the sliding groove, the locking block 43 is compressed by the inner wall of the sliding groove 31, compressing the compression spring 42 and retracting into the receiving groove 411. When the telescopic plate 4 moves to the target position, the locking block 43 pops out under the action of the compression spring 42 and embeds into the corresponding locking groove 32. Finally, rotating the unlocking screw 46 causes the limiting block of the locking housing 41 to abut against the opening of the fixing groove 44, fixing the telescopic plate 4 to the positioning plate 3 and achieving the effect of adjusting the length of the telescopic plate 4.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
