[0002] With the continuous development of society and the continuous progress of people's living standards, turnover boxes are needed more and more in the process of goods turnover. Turnover boxes can be used for storage and transportation, and have the strength of being resistant to compression and falling. As an indispensable device in the transportation process of materials or parts, generally, the weight of a turnover box is not light. In the actual production process, generally, when in use, labels are put into an empty box and then the lid is closed, and after being sent to the required position, items are put into the box to match the labels. In this process, the operations of taking and placing the turnover box and closing the lid are generally completed manually. However, due to the weight, it will consume a large amount of physical strength of workers and the efficiency is not high. To solve this problem, this application specifically proposes a box clamping, placing and lid closing device for a turnover box. Content of the Utility Model

[0019] The following further describes the present utility model in conjunction with embodiments, but is not limited to the content in the specification.
[0020] Such as Figure 1 And Figure 2As shown in the figure, the utility model relates to a box clamping, placing and lid closing device for a turnover box, which comprises a workbench 1, a gantry 2, a clamping and placing mechanism 3 and a flip cover support 4. The flip cover supports 4 are arranged in pairs and include an upright frame 41, a telescopic driving member 42 and a pick-up rod 43. The upright frame 41 is a support structure installed on the workbench 1 and capable of lifting the telescopic driving member 42 away from the surface of the workbench 1, and the lifting height is greater than the height of the turnover box. The paired upright frames 41 are arranged in parallel, and there is an interval not less than the width of the turnover box in the middle. One end of the telescopic driving member 42 is fixedly connected to the top of the upright frame 41, and the other end forms a telescopic end and is arranged towards the direction of the opposite upright frame 41. The rod body of the pick-up rod 43 is fixedly connected to the telescopic end of the telescopic driving member 42 and is arranged parallel to the surface of the workbench 1, forming a double-bar structure with a variable interval on the workbench 1. The clamping and placing mechanism 3 is installed above the workbench 1 through the gantry 2. The clamping and placing mechanism 3 includes a gripper 31 and a lifter 32. One end of the lifter 32 is connected to the gantry 2, and the other end is arranged towards the interval between the double-bar structures, and a gripper 31 capable of grasping the turnover box is installed, forming a lifting mechanism in which the lifter 32 drives the gripper 31 to approach or move away from the surface of the workbench 1.First of all, it should be noted that the device of the present utility model is aimed at at least a turnover box with a flange at the edge of the box body, which can be used to hold and apply force for handling. In the present utility model patent, a turnover box with two grooves on the two width surfaces of the box body is taken as an example. When in use, the clamping and placing mechanism 3 grabs the turnover box at the position of the other box body. It should be noted that at this time, the turnover box is in the state of opening the lid, the rotating shaft of the lid is arranged in the length direction of the box body, and the clamping position of the clamping and placing mechanism 3 is the surface in the width direction of the box body. After clamping the box body and lifting it into the air, the lid is in the state of drooping on both sides. The clamping and placing mechanism 3 moves the turnover box to the upper part of the workbench 1 through the direction set by the gantry 2. After reaching the designated position, the clamping and placing mechanism 3 gradually lowers the turnover box. The flip cover support 4 is arranged at a position close to the falling of the box body. Because the interval between the paired flip cover supports 4 is relatively large, the position of the lifting rod 43 can be exactly located on the falling path of the turnover box and corresponds to the crack between the vertically falling box lid and the side wall of the turnover box by adjusting the position through the telescopic driving member 42. During the process of the box body falling, relying on the self-weight of the box body, when the box falls, because the height of the lifting rod 43 is higher than the height of the box, as the box falls, the lifting rod 43 will lift the vertically falling box lid. When the lifting rod 43 and the upper edge of the box body are at the same horizontal height, the box lid will be lifted by the lifting rod 43 and flattened to both sides. As the turnover box continues to fall, the position of the lifting rod 43 exceeds the upper edge of the box body, and the box lids on both sides will show a state of closing towards the middle. However, because the width between the two lifting rods 43 is greater than the width of the box body, even if the position of the lifting rod 43 exceeds the height of the upper edge of the box body, the lid cannot be closed. At this time, the two telescopic driving members 42 on both sides extend towards the middle at the same time, so that the distance between the two lifting rods 43 on both sides becomes smaller until it is less than the width of the turnover box. The lifting rod 43 pushes the box lid in the closing direction, and then the box lid is closed by gravity, completing the lid closing operation. Subsequently, the lifting rod 43 is retracted by the telescopic driving member 42 to the starting position, waiting for the next turnover box to be clamped and dropped by the clamping and placing mechanism 3 for the lid closing operation;
[0021] Preferably, during the process of the turnover box falling, the telescopic driving member 42 can also drive the pick-up rod 43 to first retract from the initial position in the gap between the box body and the box cover towards the direction away from the side wall of the box body. As the box body falls, the pick-up rod 43 is then pushed out until it is less than the width of the box body to complete the lid-closing action. That is to say, during this process, with the box body itself as a reference, when the box body falls, the pick-up rod 43 is driven by the telescopic driving device 42 to move along an arc trajectory on both sides of the turnover box. As the pick-up rod 43 moves away, the pressure of the box cover on the pick-up rod 43 will become smaller, reducing the shear force on the telescopic end of the telescopic driving member and the pick-up rod itself caused by the self-weight of the box body, improving the stress state of the device during operation, and increasing the service life of the equipment; in this device, the telescopic distance of the telescopic driving member 42 does not need to be very precise, so a telescopic cylinder can be used to reduce the equipment cost and improve the convenience of equipment maintenance.
[0022] As Figure 3 shown, preferably, the upright frame 41 can either be a fixed bracket structure or a liftable bracket. Specifically, the liftable upright frame 41 includes a linear guide rail base 411, a driving slider 412, and a connecting frame 413. The linear guide rail base 411 is fixedly installed on the workbench surface of the workbench 1, and the guide rail is arranged upward. The driving slider 412 is slidably connected to the guide rail on the linear guide rail base 411 and moves up and down along the guide rail. The connecting frame 413 is fixedly connected to the driving slider. By sliding the driving slider on the guide rail, the connecting frame is driven to move up and down. The telescopic driving member 42 is installed at the end of the connecting frame 413. When in use, during the process of the clamping and placing mechanism 3 putting down the picked-up turnover box, the height of the upright frame 41 is fixed. The process of closing the lid is equivalent to the pick-up rod 43 needing to overcome the self-weight of the box cover. At the same time, the clamping and placing mechanism 3 continuously presses down the turnover box to put it down, which will also be applied to the pick-up rod 43, imposing a greater burden on the pick-up rod 43. And during the process of closing the lid with the pick-up rod 43 of fixed height, the movement trajectory of the box cover is basically fixed, and it is easy to cause the problem that the box cover hits the clamping and placing mechanism 3. When the liftable upright frame 41 is in use, in cooperation with the process of the clamping and placing mechanism 3 putting down the box body, the upright frame 41 first rises, so that the pick-up rod 43 can receive the box cover, playing a transitional role from lifting the box cover to the lid-closing action. The lid-closing action is carried out when at a high position. When the lid-closing work is about to be completed, it cooperates with the clamping and placing mechanism 3 to descend synchronously. After the clamping and placing mechanism 3 lifts away, the lid-closing is completed, and it will not hit the clamping and placing mechanism 3. Moreover, the stress burden on the pick-up rod 43 will be correspondingly reduced, improving the service life of the equipment.
[0023] In order to further improve the friction problem between the pick rod 43 and the lid of the turnover box during the lid flipping operation, preferably, in addition to using a solid rod, the pick rod 43 can also use a roller with a built-in rotating shaft. The outer surface of the pick rod 43 with such a roller structure can rotate, which greatly reduces the friction with the box lid during the above-mentioned lid flipping operation of the pick rod 43. This can not only protect the surface of the box lid, but also reduce the wear of the pick rod 43 itself, extend its service life and the interval between maintenance and repair.
[0024] The gripper 31 includes a fixed frame base 311, an extension frame 312 and a second telescopic driving member 313. The fixed frame base 311 is fixedly connected to the lifting end of the elevator 32. The extension frames 312 are respectively installed at both ends of the fixed frame base 311 in the length extension direction, forming a protruding structure facing the workbench 1 at both ends. The spacing distance between the two extension frames 312 is greater than the length of the turnover box, and the second telescopic driving members 313 are installed on both extension frames 312. The telescopic ends of the second telescopic driving members 313 are arranged oppositely and expand and contract synchronously to form a gripper capable of clamping the side wall of the turnover box. During use, the oppositely arranged second telescopic driving members 313 extend out relatively, then contact the side wall in the width direction of the turnover box and clamp the box body. The arrangement of the extension frames 312 at both ends of the fixed frame base 311 can make the second telescopic driving members 313 have a distance from the top fixed frame base 311. During the process of closing the lid, the flipping path of the box lid will not be blocked by the fixed frame base 311, ensuring that the lid closing is not hindered.
[0025] The elevator 32 includes a lifting driving member 321 and a mounting bracket 322. The lifting driving member 321 is installed on the gantry 2, and the mounting bracket 322 is fixedly connected to both the lifting end of the lifting driving member 321 and the fixed frame base 311. Specifically, the mounting bracket 322 is a right-angled triangle bracket. Such a setting can make the gripper 31 installed at the lower part laterally offset and not directly below the gantry 2, so that the position of the gantry can be shifted to the side, thus leaving a moving path for the turnover box, that is, the path for picking up the stacked boxes and sending them to the lid closing position. In this way, the gripper 31 can be directly sent to the lid closing position along the straight path of the gantry 2 at the picking position. Specifically, when the lifting driving member 321 is in use, it is respectively used to lower at the position where the boxes are stacked so that the gripper 31 can pick up the turnover box, and then raise it. After reaching above the workbench 1, the gripper 31 is lowered again, and the lid closing is completed by using the lid flipping support member 4 during this process. After landing on the workbench, the gripper 31 is released, and then the elevator 32 repeats the above lifting actions to cooperate with the gripper 31 to complete the picking and lid closing operations.
[0026] The gripper 31 also includes a gripping contact head 314, which is fixedly connected to the telescopic end of the telescopic drive member 2 313, and is provided with a convex head in the direction of the side wall of the turnover box for contacting the turnover box. In order to improve the stability when gripping the box, the gripping contact head 314 is provided on the gripper 31, especially at the end in contact with the box. Specifically, the gripping contact head 314 is made of hard silicone, which can increase the friction with the outer wall of the turnover box during gripping contact to avoid the risk of slipping.
[0027] It also includes a translation mechanism 5 installed on the gantry 2, the translation mechanism 5 includes a fixed slide rail base 51 and a slider 52, the fixed slide rail base 51 is fixedly connected to the crossbeam of the gantry 2, and has a track on the fixed slide rail base 51, the slider 52 is slidably connected to the track, and is fixedly connected to the elevator 32, forming a sliding mechanism that can link the elevator 32 to translate on the track. The translation mechanism 5 can realize the automatic setting of the whole process from the grasping position to the placing and closing position of the device. Specifically, through the sliding action of the slider 52 on the fixed slide rail base 51, the gripper 31 can be translated along the crossbeam of the gantry at two workstations. By setting the start and stop time of the mobile drive device in the control system, its translation movement between two points can be controlled. These two points can be set as the position for grasping the box body and the closing position on the corresponding table, respectively. The boxes at the grasping position can be stacked to reduce the space on the other side. The height is raised and lowered by the elevator 32 to realize the gripping of the box body, and then the translation mechanism 5 moves and slides to translate the gripper to the placing and closing position, completing the complete material picking and closing process.
[0028] The track on the fixed rail base 51 includes a driving rail 511 with a linear driver 513 and a limiting rail 512. The linear driver 513 can slide on the driving rail 511. The driving rail 511 and the limiting rail 512 are arranged in parallel. The slider 52 is fixedly connected to the linear driver 513 and is slidably connected to the limiting rail 512. Specifically, the limiting rail 512 is used to limit the slider 52 to prevent the slider from tilting and causing movement jams during the translation process after being clamped to the box. The driving rail 511 is used for the linear driver 513 to move on it and drive the slider to slide. The linear driver 513 can use a linear rail driving device.
[0029] like Figure 4As shown in the figure, in order to enable the turnover box to quickly leave the position of the lid closing operation and enter the next working station after the lid closing operation is completed, so as not to affect the lid closing operation of the subsequent turnover boxes, it further includes a roller conveyor 6. The roller conveyor 6 is laid on the workbench 1 to form a rolling conveyor surface on the workbench surface. The roller conveyor 6 includes rollers 61, a transmission mechanism 62 and a driving power source 63. The number of rollers 61 is multiple and they are arranged evenly along the length extension direction of the cross beam of the gantry 2 to form a rolling transmission channel. The driving power source 63 is fixedly installed on the workbench 1, and the power end is power-connected to the rollers 61 through the transmission mechanism 62. The transmission mechanism 62 is a gear transmission mechanism. Specifically, the roller conveyor 6 is equivalent to setting a conveyor belt on the workbench surface to move the turnover box. Among them, the multiple and evenly arranged rollers 61 can enable the turnover box to slide on it. It can be set as an inclined plane, and after the clamping device releases, it slides away relying on the gravity of the turnover box. In addition, it can also be set as a horizontal plane, and the driving power source 63 and the transmission mechanism 62 are used to actively rotate the rollers 61 to move the turnover box above. Specifically, the driving power source 63 can use a motor. Gears for transmission are provided at the ends of the rollers 61, and the gears at the ends of adjacent rollers mesh with each other. The gear at the outermost edge is power-connected to the power end of the driving power source 63. For example, by using gear meshing settings, the driving power source 63 is driven to drive all the rollers to rotate. A reduction gear can also be provided between the roller gear and the driving gear of the driving power source 63. Here, the gear transmission mechanism of this device can be adjusted adaptively according to the actual needs of the equipment to achieve the speed and torque balance of the equipment. These gears together form the transmission mechanism.
