Abstract
Description
Technical Field
[0001] This utility model belongs to the field of handling tools, specifically the field of foam box handling, and specifically relates to a handling device for foam box production. Background Technology
[0002] In the production process of foam boxes, after the foam boxes have been molded, they need to be transferred from the production line to the warehouse for storage. Currently, flatbed trucks are commonly used as the main handling tool in the industry. This is mainly due to the lightweight nature of foam boxes, which allows flatbed trucks to meet basic handling requirements.
[0003] However, due to the inherent volume of foam boxes, the number of boxes that can be carried when laid flat on a regular flatbed truck is limited. For example, a typical industrial foam box measures approximately 600mm × 400mm × 300mm, and a standard flatbed truck can only carry 8-10 boxes at a time, which is insufficient to meet the handling needs of large-scale production. To improve handling efficiency, it is usually necessary to increase the number of stacking layers of foam boxes, but as the stacking height increases, the difficulty of stacking operations increases significantly.
[0004] On the other hand, the lightweight and high center of gravity of foam boxes make them extremely unstable when stacked. Even slight shaking, collisions, or road bumps can cause the entire stack of foam boxes to tip over. In actual handling, the breakage rate due to foam box tipping is as high as 15%-20%, which not only increases production costs but also affects the timeliness of product delivery. Furthermore, to avoid the risk of tipping, workers are often forced to reduce the number of stacked layers, further limiting the amount of cargo that can be transported at one time by the flatbed truck, making it difficult to improve overall handling efficiency. Utility Model Content
[0005] This invention addresses the technical problems of difficult stacking and low handling efficiency of foam boxes by providing a handling device for foam box production. It utilizes grippers to hold foam boxes and move them upwards to reconstruct the stacking space, enabling multiple stacking operations and significantly increasing the stacking capacity of foam boxes. Furthermore, a flexible arrangement of baffles prevents foam boxes from tipping over.
[0006] This application provides a handling device for foam box production, including a flatbed cart. The flatbed cart consists of a board body and wheels disposed at the bottom of the board body. The device is characterized by: through holes evenly distributed on the top surface of the flatbed cart, and a column fixedly installed on the front side of the top surface of the flatbed cart; an operating box vertically sliding on the column; the operating box being perpendicular to the column, with an opening on its rear side; and two sliders disposed inside the operating box; the two sliders being oppositely disposed and sliding relative to each other along the operating box via a driving component; a gripper detachably mounted on one side of each slider; the gripper extending through the operating box to the rear side of the flatbed cart; and a stop bar detachably inserted into the through holes.
[0007] Based on the specifications of the foam boxes to be transported, the sliding block moves along the inside of the control box, causing the two grippers to move relative to each other on the top surface of the flatbed truck. This adjusts the position of the two grippers. Multiple levers are then used to attach them to the flatbed truck, positioned at the front and outside of the grippers respectively. The foam boxes are then stacked onto the flatbed truck, between the grippers. At this point, gaps exist between the grippers and the side walls of the foam boxes, facilitating stacking. As the number of foam boxes stacked on the flatbed truck increases, the stacking of the foam boxes... As the difficulty increases, two grippers are used to clamp one of the stacked foam boxes. Then, the operating box is moved upward along the column to clamp the foam box and transport it upward. This re-establishes a stacking space for the foam boxes on the flatbed truck, making the stacking of foam boxes simpler and increasing the number of foam boxes that can be stacked, thus improving the efficiency of foam box transportation. The stop bar is located around the foam boxes to prevent them from tipping over when stacked too high. When the stacking height of the foam boxes gradually exceeds the stop bar, the stacking operation is stopped to ensure transportation safety.
[0008] In one specific implementation, the column includes a polygonal column body and a stud coaxially disposed on the bottom surface of the column body; the stud penetrates downward through the flatbed truck and is threadedly connected to a nut; the column body is assembled with the operating box via an assembly.
[0009] The polygonal column guides and constrains the control box, allowing it to move smoothly vertically. The column is fixed to the flatbed truck with studs and nuts, making operation simple and reliable.
[0010] In one specific implementation, the assembly includes a sleeve that slides onto the column; the sleeve is connected to the column by a locking member, and a wing plate is provided on the sleeve; the wing plate is detachably connected to the operating box by bolts; and a handrail is fixedly provided on the sleeve.
[0011] The sleeve that slides with the column is fixed to the control box via a wing plate. The handle on the sleeve facilitates the adjustment of the sleeve and the lifting and moving of the control box, and the locking device is used to fix the position of the sleeve and the control box, making it flexible to use.
[0012] In one specific implementation, the locking element includes a mounting hole on the outer wall of the sleeve, a threaded sleeve is fitted inside the mounting hole; the threaded sleeve is fixedly connected to the sleeve, and a tightening bolt is threadedly connected to the threaded sleeve; one end of the tightening bolt abuts against the column, and the other end is fixedly connected to a handle.
[0013] The threaded tube is fixed on the sleeve, providing an installation position for the tightening bolt and sufficient strength support for its use, ensuring reliable operation.
[0014] In one specific implementation, the driving component includes a bidirectional lead screw movably mounted in the control box; one end of the bidirectional lead screw passes through the control box and is fixedly connected to the power structure, and both ends of the bidirectional lead screw are fitted with nuts; the nuts are respectively fixedly fitted with sliders.
[0015] The slider moves relative to the other side via a bidirectional lead screw, resulting in a simple structure and stable and reliable operation.
[0016] In one specific feasible implementation, the power structure is a handwheel.
[0017] The operation is simple, as the double-acting screw is rotated by handwheel.
[0018] In one specific implementation, a protective bushing is fixedly fitted inside each of the through holes, and the protective bushing is interference-fitted with the stop bar; a limit ring is fixedly fitted to the bottom of the outer side wall of the stop bar; the limit ring abuts against the top surface of the flatbed.
[0019] The protective bushing enhances the protection of the through hole, reduces wear on the through hole, and extends the service life of the flatbed. The protective bushing is also replaceable, improving the flexibility of use. Furthermore, after the stop bar is inserted into the protective bushing, the limiting ring supports the stop bar, ensuring reliable use.
[0020] In one specific implementation, the inner wall of the protective bushing is provided with an annular groove, and the bottom of the outer wall of the stop bar is fixedly fitted with an annular clamp; the clamp engages with the groove.
[0021] The clamps on the stop lever engage with the grooves on the protective bushing, enhancing the assembly strength of the stop lever and the protective bushing and ensuring reliable use.
[0022] In one specific implementation, the outer wall of the gripper is fitted with a rubber sleeve.
[0023] The rubber sleeve prevents the clamps from damaging the foam box, ensuring safe use.
[0024] In one specific implementation, the top surface of the flatbed is coated with a Teflon coating.
[0025] The Teflon coating reduces the frictional resistance between the flatbed truck and the foam box, making loading and unloading easier. Attached Figure Description

[0039] Please see the appendix Figure 1 Appendix Figure 3 Appendix Figure 5 A handling device for foam box production includes a flatbed trolley 1, which consists of a board body and wheels mounted on the board body. The flatbed trolley 1 has through holes 101 evenly distributed on it. The through holes 101 are located on the board body, which reduces the weight of the flatbed trolley 1. A column 2 is fixedly installed on the front of the top of the flatbed trolley 1. An operating box 3 is vertically slidable on the column 2. The operating box 3 is perpendicular to the column 2. The column 2 includes a polygonal column body 201. A stud 202 is coaxially mounted on the bottom surface of the column body 201. The stud 202 penetrates the flatbed trolley 1 downward and is threaded with a nut 203. After the nut 203 abuts against the bottom surface of the flatbed trolley 1, the column body 201 is tightened and fixed on the flatbed trolley 1. The column body 201 is assembled with the operating box 3 by means of an assembly.
[0040] Please see the appendix Figure 2 Appendix Figure 5 Appendix Figure 6The fitting used for assembling the column 201 is a sleeve 7 that slides onto the column 201. The inner wall of the sleeve 7 corresponds to and matches the shape of the outer wall of the column 201. The polygonal column 201 constrains the sleeve 7, making the sleeve 7 slide stably along the column 201 vertically. The sleeve 7 is provided with a protruding wing plate 701, which is fixed to the operating box 3 by bolts. Its assembly structure is simple, making disassembly and assembly convenient and efficient. A handle 702 is fixedly installed on the sleeve 7, which facilitates the adjustment of the sleeve 7 along the column 201. The upper and lower sliding of 1 adjusts the position of the operating box 3. The sleeve 7 is also equipped with a locking component, which includes a mounting hole 703 on the outer wall of the sleeve 7. A threaded sleeve 8 is installed in the mounting hole 703. The threaded sleeve 8 and the sleeve 7 can be fixed by welding. A tightening bolt 9 is connected to the threaded thread of the threaded sleeve 8. One end of the tightening bolt 9 abuts against the column 201, thereby locking the sleeve 7 to the column 201. The other end of the tightening bolt 9 is fixedly connected to a handle 901. The handle 901 can be a plum blossom handle 901 for comfortable operation.
[0041] Please see the appendix Figure 1 Appendix Figure 7 The control box 3 has a horizontal opening at its rear and contains two sliders 4. The two sliders 4 slide relative to each other within the control box 3 via a driving mechanism. The driving mechanism includes a bidirectional lead screw 10 rotatably mounted within the control box 3. Each bidirectional lead screw 10 is fitted with two nuts 1001, which are fixedly mounted to the sliders 4. One end of the bidirectional lead screw 10 passes through the control box 3 and is equipped with a power mechanism. The power mechanism can be selected using a handwheel 1002, allowing manual rotation of the bidirectional lead screw 10 to drive the two sliders 4 to move within the control box 3, providing flexible operation. Furthermore, the power structure can be driven by an electric motor. The drive motor is fixedly mounted on the operating box 3 via a motor support, and the output shaft of the drive motor is connected to the bidirectional lead screw 10 via a transmission component, such as a gearbox or a transmission belt, thereby driving the bidirectional lead screw 10 and the slider 4 to run, improving the level of automation. However, the motor will be limited by its range, reducing the flexibility of use, and the maintenance cost will be high. In addition, the slider 4 can be detachably mounted with grippers 5 for clamping foam boxes. Since the required clamping force is not large, the handwheel 1002 is preferred for driving.
[0042] Please see the appendix Figure 4 Appendix Figure 8 Appendix Figure 9When handling foam boxes, the outer wall of the gripper 5 is fitted with a rubber sleeve 501. After adjusting the gripper 5 to a suitable position, the stop bar 6 is placed outside the gripper 5 and inserted into the through hole 101 on the top surface of the flatbed trolley 1. Each through hole 101 is fitted with a protective bushing 11. The protective bushing 11 prevents wear between the baffle and the through hole 101 and facilitates subsequent maintenance and replacement, extending the service life of the flatbed trolley 1. The inner side wall of the protective bushing 11 is provided with an annular groove 1101. The bottom of the outer side wall of the stop bar 6 is fixedly fitted with an annular clamp 601. The clamp 601 engages with the groove 1101, enhancing the firmness of the connection between the stop bar 6 and the through hole 101. The bottom of the outer side wall of the stop bar 6 is fixedly fitted with a limit ring 602. The limit ring 602 abuts against the top surface of the flatbed trolley 1, thereby supporting the stop bar 6 and ensuring safety during use. The stop bar 6 prevents the foam boxes from tipping over when stacked too high, ensuring safety during transportation.
[0043] The working principle of the handling device for foam box production is as follows: according to the specifications of the foam box to be handled, the position of the two grippers 5 is adjusted by rotating the double-acting screw 10, and at least six stops 6 are taken. Two of them are inserted into the front of the flatbed trolley 1, and their positions are located on both sides of the uprights 2. Then the other uprights 2 are evenly placed on the outside of the grippers 5 and inserted into the protective bushings 11 in the through holes 101. The foam boxes are then moved to the top of the flatbed trolley 1 and placed between the two grippers 5. Taking a single foam box with dimensions of approximately 600mm×400mm×300mm as an example, the position indication of the grippers 5 and the position constraint of the stop bar 6 reduce the requirements for the stacking position of the foam boxes, ensuring stacking accuracy and improving stacking efficiency. After stacking 6-8 foam boxes, which makes subsequent stacking more difficult, the operator rotates the double-acting screw 10 to clamp one of the foam boxes with the grippers 5. The sleeve 7 is then moved upward along the column 2 by the handle 702, and the sleeve 7 is locked with the tightening bolt 9. This re-establishes the stacking space for the foam boxes on the flatbed trolley 1 so that the foam boxes can continue to be stacked. The preferred method for lifting and moving foam boxes is to select those in the middle or upper middle position on the flatbed trolley 1, such as the third or fourth layer. This facilitates stacking other foam boxes on top of the existing ones, reduces the lifting force required by the grippers 5, and is labor-saving, flexible, and allows for multiple stacking operations. This enables the stacking of 6-8 layers of foam boxes, increasing the number of stacked foam boxes transported and improving handling efficiency. The baffle 6 is located around the foam boxes to prevent them from tipping over due to excessive stacking. Stacking stops when the stacked foam boxes exceed the baffle 6, ensuring transport safety. After stacking, the grippers 5 hold the middle layer of foam boxes, distributing the weight of the bottom layer and improving the overall stability of the foam boxes during transfer.
