Description

Technical Field

[0001] This utility model relates to the field of material box conveying, and in particular to a cross-line return material rack. Background Technology

[0002] When using a zigzag cyclic speed-up line, the operator stands inside the line, and the logistics personnel need to pass the material box from the outside to the operator inside. There should be no obstruction between the height of the line and 1520mm. Passing the material box during movement will affect the rhythm and is unsafe.

[0003] Specifically, a zigzag double-speed conveyor line typically has two intersecting conveyor belts. The input end and inner side of the input conveyor belt for material boxes intersect with another output conveyor belt. Operators on the outer side and output end of the input conveyor belt need to remove the material and return the empty material box to the output conveyor belt located at the intersection, so that operators at the output conveyor belt at the intersection can perform other operations on the material box.

[0004] If traditional manual handling is used in the workshop, it will disrupt the conveyor belt rhythm and reduce work efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a cross-line return material rack that facilitates the return of materials from the input conveyor belt to the output conveyor belt.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A cross-line return material rack includes a return material rack, an outer lifting platform, an inner lifting platform, a middle flow strip slide, an outer lifting component, and an inner lifting component.

[0008] The return material rack is an internally connected gantry frame structure, including inner legs, crossbeams and outer legs, all of which are rectangular frames. The inner legs and outer legs are arranged opposite to each other, and the two ends of the horizontal crossbeam are perpendicular to the tops of the inner legs and outer legs.

[0009] The outer lifting platform is vertically slidably connected to the outer support leg, and the outer lifting component connected to the return material rack drives the outer lifting platform to rise and fall inside the outer support leg;

[0010] The inner lifting platform is vertically slidably connected to the inner support leg, and the inner lifting component connected to the return material rack drives the inner lifting platform to rise and fall inside the inner support leg;

[0011] The inclined middle slide is set in the crossbeam, and the outer lifting platform is provided with an outer flow strip slide. After receiving the material box, the outer lifting platform rises to the outer flow strip slide and connects with the middle flow strip slide. The material box slides down through the middle slide to the inner lifting platform and then descends.

[0012] Furthermore, the outer lifting platform is provided with an inclined outer flow rail slide, and the inclination angle of the outer flow rail slide is the same as that of the middle flow rail slide.

[0013] The outer support leg is provided with a baffle bar located below the input end of the middle flow rail slide, the baffle bar being used to prevent the material box from rushing out of the outer support leg.

[0014] Furthermore, the outer lifting component includes a handle and two sets of pulley rope assemblies respectively disposed at both ends of the outer lifting platform. The pulley rope assembly includes an outer rope with a U-shaped path opening downwards and multiple pulleys disposed on the return material rack.

[0015] The handle is located on the outside of the outer support leg. Two sliders that slide with the outer support leg are fixed at both ends of the handle. One end of the outer rope is fixed on each slider. The other end of the outer rope is guided upward through multiple pulleys and then fixed downward to the outer lifting platform.

[0016] Pulling down the handle lever raises the outer lifting platform; releasing the handle lever lowers the outer lifting platform.

[0017] Furthermore, the outer support leg is provided with a positioning block to prevent the handle from moving upward. Pulling the handle downward will raise the outer lifting platform; releasing the handle will lower the outer lifting platform and move the handle upward to the positioning block.

[0018] Furthermore, the outer support leg is provided with a positioning plate to prevent the outer lifting platform from moving downward. Pulling the handle downward will raise the outer lifting platform; releasing the handle will lower the outer lifting platform to the positioning plate, and the handle will move upward.

[0019] Furthermore, inner sliders are fixed to the bottom surface at the four corners of the inner lifting platform, and the inner sliders are slidably connected to the inner support legs.

[0020] The inner lifting component includes a dual-axis motor disposed on the top surface of the inner support leg and a winding spool disposed on the output shaft of each dual-axis motor;

[0021] An inner rope is wound on the reel, and the motor controls the two reels to wind and unwind the inner rope, causing the inner rope to lift both ends of the inner lifting platform downwards.

[0022] Furthermore, the outer lifting platform is provided with a docking rod, and when the docking rod abuts against the middle flow strip slide, the outer lifting platform docks with the middle flow strip slide.

[0023] Furthermore, the outer lifting platform is provided with outer sliders at each of its four corners, which are slidably fitted with the outer support legs.

[0024] Furthermore, the length direction of the input conveyor belt is along the length direction of the crossbeam, the return material rack is arranged above the input conveyor belt, and the output end of the input conveyor belt is close to the outer lifting platform;

[0025] The input end of the output conveyor belt is located outside the inner support leg and below the crossbeam;

[0026] The inner lifting platform is equipped with an inner flow rail, through which the material box can be pushed into the output conveyor belt.

[0027] In the above technical solution, the present invention has the following beneficial effects:

[0028] In operation, the outer lifting mechanism of the cross-line return rack drives the outer lifting platform to lift the material box. The material box then slides into the middle flow channel inside the line. Workers inside the line operate the inner lifting mechanism to lower the inner lifting platform to retrieve the material. Continuing to lower the inner lifting platform, the empty material box slides onto the output conveyor belt, facilitating subsequent operations such as retrieving empty boxes via a belt conveyor. The transfer of material boxes and materials via the cross-line return rack on the two intersecting conveyor belts avoids the time-consuming and labor-intensive problem of manual handling, while maintaining a regular transfer rhythm.

[0035] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0036] It should be noted that the terms "above," "one end," "up," etc. used in this document indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Similar expressions are only for illustrative purposes and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "part," "two parts," etc. are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0037] like Figure 1-3 The cross-line return material rack shown includes a return material rack 1, an outer lifting platform 3, an inner lifting platform 4, a middle flow strip slide 5, an outer lifting component 6, and an inner lifting component 2.

[0038] The return material rack 1 is an internally connected gantry-type frame structure, comprising inner legs, crossbeams, and outer legs, all of which are rectangular frames. The inner and outer legs are arranged opposite each other, and the ends of the horizontal crossbeams are perpendicular to the tops of the inner and outer legs. In use, the outer legs are close to the output end of the input conveyor belt supplying the material box, and the inner legs are close to the intersection of the output conveyor belt, which intersects with the input conveyor belt.

[0039] The outer lifting platform 3 is vertically slidably connected to the outer support leg, and the outer lifting component 6 connected to the return material rack 1 drives the outer lifting platform 3 to rise and fall inside the outer support leg.

[0040] The inner lifting platform 4 is vertically slidably connected to the inner support leg. The inner lifting component 2, connected to the return material rack 1, drives the inner lifting platform 4 to rise and fall inside the inner support leg. The outer and inner lifting platforms are used to receive the material box.

[0041] An inclined intermediate flow channel 5 is installed in the crossbeam, and an outer flow channel 5 is installed inside the outer lifting platform 3. The higher end and input end of the outer flow channel 5 face the outer support leg, and the lower end faces the inner support leg. After receiving the material box from the input conveyor belt, the outer lifting platform 3 rises to the outer flow channel 5 and connects with the intermediate flow channel 5. Baffles are respectively installed on both sides of the return material rack 1 in the width direction of the outer lifting platform 3, the intermediate flow channel 5, and the inner lifting platform 4 to prevent the material box from rushing out of the return material rack 1. The material box slides down through the intermediate flow channel 5 to the inner lifting platform 4 and then descends.

[0042] Material boxes on the input conveyor belt are manually moved to the outer fluid strip slide on the outer lifting platform. When the outer lifting platform rises to the corresponding position on the middle fluid strip slide 5 and the outer fluid strip slide is horizontal, the material box can be manually pushed onto the middle fluid strip slide 5, and then the inner lifting platform 4 receives the material box. The inner lifting platform has baffles on the width of the return material rack 1 and on the side opposite to the middle fluid strip slide 5 to prevent the material box from being pushed off the inner lifting platform 4. Baffles are provided on three sides of the inner lifting platform 4, except for the side facing the middle fluid strip slide 5. Alternatively, the inner support legs can be widened to prevent the material box from leaving the inner support legs. Driven by the inner lifting component 2, the inner lifting platform 4 moves downward. As needed, the material box filled with material can be lowered directly and manually transported to the output conveyor belt. Alternatively, as needed, the inner lifting platform 4 can be lowered partially to pick up and put down the material before lowering the inner lifting platform to manually transport the empty material box to the output conveyor belt.

[0043] In order to allow the material on the outer lifting platform to automatically slide into the middle fluid strip slide, the outer lifting platform 3 is equipped with an inclined outer fluid strip slide, and the inclination angle of the outer fluid strip slide is the same as that of the middle fluid strip slide 5.

[0044] A baffle 11 is provided on the outer support leg below the input end of the middle fluid strip slide 5. The material box is placed at an angle on the middle fluid strip slide, and the baffle 11 prevents the material box from rushing out of the outer support leg.

[0045] The outer lifting component 6 is used to lift the outer lifting platform, and can refer to the prior art or the preferred embodiments described later. In the prior art, the outer lifting component 6 can be a vertical cylinder, one end of which is fixed to the return material rack, and the free end of which is fixed to the bottom surface of the outer lifting platform. The cylinder pushes the outer lifting platform to move.

[0046] Preferably, the outer lifting component 6 includes a handle 31 and two sets of pulley rope assemblies respectively disposed at both ends of the outer lifting platform 3. The pulley rope assembly includes an outer rope with a U-shaped path opening downwards and multiple pulleys 32 disposed on the return material rack 1.

[0047] The handle lever 31 is positioned on the outer side of the outer support leg, away from the inner support leg. Two sliders 311, which slide and engage with the outer support leg, are fixed to both ends of the handle lever 31, enabling a vertical sliding connection between the handle lever 31 and the outer support leg. One end of an outer rope is fixed to each slider 311, and the other end of the outer rope is guided upwards through multiple pulleys 32 and then fixed downwards to the outer lifting platform 3. The outer lifting platform 3 is pulled up at both ends along the width direction of the return material rack 1 by the outer ropes.

[0048] Because the length of the outer rope is fixed, pulling down the handle 31 raises the outer lifting platform 3; releasing the handle 31 lowers the outer lifting platform 3 and raises the handle 31. In use, after manually pulling down the handle 31 and the material box leaving the outer lifting platform, releasing the handle 31 allows its own weight to position it on the outer support leg, at which point the outer lifting platform descends to near the input conveyor belt.

[0049] To prevent the material box from falling excessively due to its weight, a positioning block is installed on the outer support leg to prevent the handle 31 from moving upward. Pulling the handle 31 downward raises the outer lifting platform 3; releasing the handle 31 lowers the outer lifting platform 3 and moves the handle 31 upward to the positioning block. The positioning block protects the material box from colliding with the ground or being fed onto the conveyor belt.

[0050] To prevent the material box from falling excessively due to its weight, a positioning plate is installed on the outer support leg to prevent the outer lifting platform 3 from moving downwards. Pulling down the handle lever 31 raises the outer lifting platform 3; releasing the handle lever 31 lowers the outer lifting platform 3 to the positioning plate, and the handle lever 31 moves upwards. The positioning plate serves to protect the material box from impacting the ground or entering the conveyor belt.

[0051] Preferably, inner sliders 41 are fixed to the bottom surface at each of the four corners of the inner lifting platform 4, and the inner sliders 41 are slidably connected to the inner support legs. Guide rails that cooperate with the inner sliders 41 are provided at the four corners of the inner support legs.

[0052] The structure of the inner lifting component 2 is existing technology. Preferably, it includes a dual-axis motor 21 mounted on the top surface of the inner support leg and a winding spool mounted on the output shaft of the dual-axis motor 21. An inner rope is wound on the winding spool, and the dual-axis motor 21 controls the two winding spools to wind and unwind the inner rope, causing the inner rope to lift both ends of the inner lifting platform 4 downwards. Depending on the operational requirements, the inner lifting platform 4 can be equipped with multiple stopping points.

[0053] Preferably, the outer lifting platform 3 is equipped with a connecting rod (not shown in the figure) that can abut against the bottom surface of the input end of the middle flow strip slide 5. When the connecting rod abuts against the middle flow strip slide 5, the outer lifting platform 3 is connected to the middle flow strip slide 5. The function of the connecting rod is to prevent the middle flow strip slide 5 from moving upward too far or too fast and missing the middle flow strip slide 5. The connecting rod also has a positioning function.

[0054] The outer lifting platform 3 has outer sliders 33 at each of its four corners that slide with the outer outriggers. The outer outriggers also have guide rails at each of their four corners that slide with the outer sliders 3.

[0055] Preferably, the length direction of the input conveyor belt 8 for the material box is along the length direction of the crossbeam, the return material rack 1 is set above the input conveyor belt 8, and the output end of the input conveyor belt 8 is close to the outer lifting platform 3, so as to facilitate the material box on the output end of the input conveyor belt 8 to be moved onto the outer lifting platform 3.

[0056] The output conveyor belt 9 intersects with the input drive belt 8. The input end of the output conveyor belt 9 is located outside the inner support leg and below the crossbeam. An inner flow rail is provided on the inner lifting platform 4, through which the material box can be pushed into the output conveyor belt 9. The inner flow rail can be set horizontally or at an angle.

[0057] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
