Description

Technical Field

[0001] This application belongs to the field of forklift fork technology, and in particular relates to a material rotation and ejection device for forklifts. Background Technology

[0002] Forklifts are widely used in warehousing and logistics, manufacturing, ports and docks, construction sites and other scenarios. Forklifts use the forks at the front end to lift, move and stack palletized goods or large materials.

[0003] In actual operation, the forks of existing forklifts are usually fixed rod-shaped or plate-shaped structures that can only be inserted into the pallet holes at the bottom of the goods. The goods are lifted and moved by the lifting mechanism of the forklift itself. However, when the goods need to be unloaded from the pallet, since the forks are always supporting the bottom of the pallet, manual assistance is required to separate the pallet from the goods, or the forklift is repeatedly adjusted to try to separate them. This not only increases labor costs, but may also cause the goods to tilt or scatter due to improper operation. At the same time, the traditional unloading method requires operating the forklift to reverse as a whole to pull the forks out from under the pallet. However, during the reversing process, the goods are easily moved synchronously with the forklift, resulting in the deviation of the goods stacking position, or even causing safety accidents such as the goods tipping over or being damaged.

[0004] To address these issues, we provide a forklift material rotation and ejection device. Summary of the Invention

[0005] The purpose of this application is to provide a material rotation and ejection device for forklifts. It is a multi-component collaborative structure that uses a clamping component to firmly clamp the goods vertically, a blocking component to prevent the goods from slipping laterally, a rotating component to flexibly flip and turn the goods, and a pushing component to smoothly eject the goods. Combined with the precise drive of power components such as clamping cylinders, drive motors, and adjusting cylinders, as well as the adaptable design of multi-directional adjustment of the pusher frame and elastic auxiliary adjustment of the ejector, it solves the problems of existing forklift forks being able to only carry and move goods in a single direction, unable to fix and protect the goods in multiple directions, resulting in easy slippage during handling, difficulty in flipping the goods to separate the pallet, and inconvenience in unloading.

[0006] To solve the above-mentioned technical problems, this application provides the following technical solution: This application discloses a material rotation and ejection device for a forklift, comprising a clamping assembly including a lower crossbar and an upper crossbar that are parallel to each other.

A movable crossbar is movably sleeved inside the fixed crossbar. A right fixed upright and a right movable upright are fixedly connected to opposite sides of the two fixed crossbars, and the right movable upright is movably sleeved inside the right fixed upright from above. A left fixed upright and a left movable upright are fixedly connected to opposite sides of the two movable crossbars, and the left movable upright is movably sleeved inside the left fixed upright from above. A side baffle for blocking goods from the side is fixedly connected to the front of the left fixed upright and the left movable upright.

[0008] This application further specifies that a clamping cylinder is fixedly connected inside the fixed sliding groove plate, and the output end of the clamping cylinder is fixedly connected to the inside of the movable sliding groove plate through a connecting pin.

[0009] This application further specifies that the pusher includes a plurality of first crossbars equidistantly fixed to the movable end of the scissor telescopic machine, a second crossbar movably sleeved inside each of the plurality of first crossbars, a second longitudinal bar orthogonally fixed to the outside of the plurality of second crossbars, a second sliding longitudinal bar slidably connected inside the second longitudinal bar, a plurality of first longitudinal bars equidistantly fixed to the front of the plurality of first crossbars, a first sliding longitudinal bar movably sleeved inside each of the plurality of first longitudinal bars, a top crossbar fixedly connected to the front of the plurality of first sliding longitudinal bars, a top sliding rod movably sleeved inside the top crossbar, and the top sliding rod fixedly connected to the outside of the second sliding longitudinal bar, and an electric telescopic rod fixedly connected to the back of the plurality of first crossbars, and the output end of the electric telescopic rod fixedly connected to the outside of the top crossbar.

[0010] This application further specifies that the two ejectors include two sliding sleeves respectively fixedly connected to the back of the top crossbar and the first crossbar, and ejector rods are movably sleeved inside the two sliding sleeves. One end of each ejector rod is fixedly connected to the outside of the second sliding longitudinal bar and the second longitudinal bar, and a retaining ring is fixedly connected to the outside of each ejector rod. A spring for pushing the retaining ring is movably sleeved on the outside of each ejector rod.

[0011] This application further specifies that a toothed ring is fixedly connected to the outside of the rotating collar, a drive motor is fixedly connected to the inside of the mounting bracket, and a drive gear that meshes with the toothed ring is fixedly connected to the output end of the drive motor.

[0012] This application is further configured such that an adjusting cylinder is fixedly connected to the top of the front of the plurality of first sliding uprights and the bottom of the front of the plurality of first fixed uprights, and the output ends of the two adjusting cylinders are respectively fixedly connected to the outside of the left movable upright and the left fixed upright.

[0013] The present application further specifies that the side baffle includes a fixed side plate fixedly connected to the front of the left fixed upright and a comb-shaped plate fixedly connected to the front of the left movable upright, and the comb-shaped plate is movably inserted into the interior of the fixed side plate. A baffle plate is fixedly connected to the inner side of the comb-shaped plate and the baffle plate is attached to the inner side of the fixed side plate.

[0014] This application also provides a material pushing method for a forklift material rotary ejection device, comprising the following steps for stacking materials: S1. Move the forklift to the location of the goods to be transported, adjust the position of the forklift so that the two arms of the clamping assembly are aligned with the pallet insertion holes at the bottom of the goods, and slowly insert the arms into the pallet until the top baffle is close to the back of the goods to complete the initial positioning. At this time, the fixed sliding groove plate and the movable sliding groove plate are in the initial open state, ready for subsequent clamping. S2. Activate the clamping cylinder inside the fixed sliding groove plate. The output end of the clamping cylinder pushes the movable sliding groove plate to slide along the inside of the fixed sliding groove plate through the connecting pin, causing the lower crossbar and the upper crossbar to move closer together. At the same time, the first sliding upright at the bottom of the upper crossbar slides down along the inside of the first fixed upright at the top of the lower crossbar, so that the top baffle fits tightly against the top of the goods, and works with the insert arm to clamp the goods from the top and bottom to prevent the goods from shifting. S3. Start the adjusting cylinder. The adjusting cylinder located at the top front of the first sliding upright pushes the left movable upright to slide down along the inside of the left fixed upright. The adjusting cylinder located at the bottom front of the first fixed upright pushes the left fixed upright to move laterally. At the same time, the movable crossbar inside the fixed crossbar extends outward, and the right movable upright slides along the inside of the right fixed upright for adjustment. Finally, the fixed side plate of the side baffle and the comb plate are close to the side of the goods, and the baffle plate is close to the inside of the goods, blocking the goods from the side and forming all-round protection. S4. Start the drive motor of the rotating component. The output end of the drive motor drives the drive gear to rotate. The drive gear meshes with the toothed ring outside the rotating collar, causing the rotating collar to rotate around the rotating shaft on the mounting frame. The front frame rotates synchronously with the rotating collar, thereby driving the clamping component and the goods to rotate 180 degrees. After the rotation is completed, close the drive motor and lock the position. At this time, the top baffle lifts the goods. S5. Start the scissor telescopic conveyor of the pushing assembly. The movable end of the scissor telescopic conveyor drives the pushing frame to extend towards the goods. The first longitudinal bar, the second longitudinal bar and the top crossbar of the pushing frame work together to smoothly push the goods from the insert arm to the target position. At the same time, the pallet can also be easily removed.

[0015] This application has the following beneficial effects: This application achieves secure clamping, flexible steering, and side anti-detachment protection for goods of different sizes by using the upper and lower opening and closing adjustment structure of the clamping assembly in conjunction with the power of the clamping cylinder, the meshing transmission rotation structure of the rotating assembly, and the multi-directional adjustable side stop structure of the stop assembly. This ensures the stability and safety of goods during handling and rotation, while also allowing for easy removal of the pallet, thus improving work efficiency.

[0016] This application achieves the smooth pushing of goods of different heights and lengths through the stable pushing capability of the scissor telescopic mechanism in the pushing assembly, the multi-directional adjustable frame structure of the pushing frame, and the elastic auxiliary length adjustment function of the ejector.

[0026] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Specific Implementation Example 1 Please see Figures 1 to 7This application discloses a material rotation and ejection device for a forklift, comprising a clamping assembly 100, including a lower crossbar 101 and an upper crossbar 102 parallel to each other. The top of the lower crossbar 101 is fixedly connected to fixed sliding groove plates 103 near both ends, and the bottom of the lower crossbar 101 is fixedly connected to movable sliding groove plates 104 slidably connected inside the corresponding fixed sliding groove plates 103 near both ends. The top of the lower crossbar 101 is fixedly connected to a plurality of parallel first fixed uprights 105, and the bottom of the upper crossbar 102 is fixedly connected to a plurality of first sliding uprights 106 movably sleeved inside the corresponding first fixed uprights 105. Two insert arms 107 for inserting pallets are fixedly connected to the front of the crossbar 101, and a top baffle 108 for clamping goods is fixedly connected to the front of the upper crossbar 102. The clamping assembly 100 is arranged in parallel with the lower crossbar 101 and the upper crossbar 102, and can realize the opening and closing adjustment in the vertical direction by means of the sliding connection between the fixed sliding groove plate 103 and the movable sliding groove plate 104, and the movable sleeve connection between the first fixed upright tube 105 and the first sliding upright 106. The insert arms 107 can be stably inserted into the pallet to complete the carrying of goods, and the top baffle 108 can be attached to the goods from above, initially forming a vertical limit, laying the foundation for subsequent clamping of goods. The rotating assembly 300 includes a mounting frame 302 located on the back of the clamping assembly 100 and a front frame 301 fixedly connected to the back of a plurality of first fixed uprights 105. A rotating collar 304 is fixedly connected to the side of the front frame 301 facing the mounting frame 302. A rotating shaft 303 rotatably connected inside the rotating collar 304 is fixedly connected to the side of the mounting frame 302 facing the front frame 301. The front frame 301 is fixed to the clamping assembly 100. The mounting frame 302 serves as a fixed base. The rotational engagement between the rotating collar 304 and the rotating shaft 303 enables the front frame 301 to drive the clamping assembly 100 to rotate around the rotating shaft 303, thereby adjusting the direction of the goods. It also includes a baffle assembly 400, which includes fixed crossbars 401 fixedly connected to the bottom of the top baffle 108 and the top of the two insert arms 107 respectively. A movable crossbar 402 is movably sleeved inside the fixed crossbars 401. A right fixed upright 403 and a right movable upright 404 are fixedly connected to opposite sides of the two fixed crossbars 401 respectively, and the right movable upright 404 is movably sleeved inside the right fixed upright 403 from above. A left fixed upright 405 and a left movable upright 406 are fixedly connected to opposite sides of the two movable crossbars 402 respectively, and the left movable upright 406 is movably sleeved inside the right fixed upright 403 from above. Inside the left fixed upright 405, a side baffle 408 for blocking goods from the side is fixedly connected to the front of the left fixed upright 405 and the left movable upright 406. The baffle assembly 400 can flexibly adjust the lateral position and height of the side baffle 408 by the movable sleeve of the fixed crossbar 401 and the movable crossbar 402, the upper and lower sleeve of the right fixed upright 403 and the right movable upright 404, and the upper and lower sleeve of the left fixed upright 405 and the left movable upright 406, so that it can adapt to goods of different sizes, form an effective blockage from the side, prevent goods from slipping from the side during handling or rotation, and further improve the stability of the goods.

[0028] Specifically, a clamping cylinder 109 is fixedly connected inside the fixed sliding trough plate 103, and the output end of the clamping cylinder 109 is fixedly connected to the inside of the movable sliding trough plate 104 through a connecting pin. The clamping cylinder 109 provides power for the opening and closing of the clamping assembly 100. By pushing the movable sliding trough plate 104 along the fixed sliding trough plate 103 through the output end, the relative proximity of the lower crossbar 101 and the upper crossbar 102 can be controlled, thereby ensuring that the goods are firmly clamped. A gear ring 305 is fixedly connected to the outside of the rotating collar 304, and a drive motor 306 is fixedly connected to the inside of the mounting bracket 302. A drive gear 307 that meshes with the gear ring 305 is fixedly connected to the output end of the drive motor 306. The drive motor 306 transmits power to the rotating collar 304 through the meshing of the drive gear 307 and the gear ring 305, thereby driving the clamping assembly 100 to rotate. Adjusting cylinders 407 are fixedly connected to the top front of multiple first sliding uprights 106 and the bottom front of multiple first fixed uprights 105. The output ends of the two adjusting cylinders 407 are fixedly connected to the outside of the left movable upright 406 and the left fixed upright 405, respectively. The adjusting cylinders 407 provide power for the up-and-down movement of the left movable upright 406 and the lateral movement of the left fixed upright 405, thereby enabling them to quickly adapt to goods of different heights and widths. The side baffle 408 includes a fixed side plate 408a fixedly connected to the front of the left fixed upright 405 and a comb plate 408b fixedly connected to the front of the left movable upright 406. The comb plate 408b is movably inserted into the interior of the fixed side plate 408a. A baffle plate 408c is fixedly connected to the inner side of the comb plate 408b and fits against the inner side of the fixed side plate 408a. The side baffle 408 adopts a structure in which the fixed side plate 408a and the comb plate 408b are movably inserted. When the left movable upright 406 moves the comb plate 408b up and down, the height of the side baffle 408 can be flexibly adjusted. The insertion structure can ensure stability during the adjustment process.

[0029] The operation process of this embodiment is as follows: When it is necessary to flip the goods and remove the pallet, firstly, the clamping cylinder 109 is activated. Its output end pushes the movable sliding groove plate 104 to slide along the inside of the fixed sliding groove plate 103 through the connecting pin, driving the upper crossbar 102 to move closer to the lower crossbar 101. At the same time, the first sliding upright 106 slides down synchronously along the inside of the first fixed upright 105 until the top baffle 108 is tightly attached to the top of the goods and the insert arm 107 stably supports the bottom of the goods, completing the clamping and fixing of the goods in the vertical direction. Then, according to the width of the goods, the adjusting cylinder 407 connected to the left fixed upright 405 is activated, pushing the movable crossbar 402 to slide along the inside of the fixed crossbar 401, driving the left fixed upright 405 and the left movable upright 406 to move laterally, so that the side baffle 408 is attached to the side of the goods. Then, the adjusting cylinder 407 connected to the left movable upright 406 is activated, pushing the left movable upright 406 to move laterally. The forklift slides up and down along the inside of the left fixed upright 405, causing the comb plate 408b to move along the inside of the fixed side plate 408a until the baffle plate 408c completely covers the side height of the goods, forming a side limit. At the same time, the right movable upright 404 adjusts synchronously along the right fixed upright 403 to ensure the force balance on both sides. Then, the drive motor 306 is started, and its output end drives the drive gear 307 to rotate. Through the meshing transmission between the drive gear 307 and the gear ring 305, the rotating collar 304 is driven to rotate along the rotating shaft 303, which in turn causes the front frame 301 to drive the clamping assembly 100 and the goods to flip around the rotating shaft 303. At this time, the pallet is facing up and the goods are facing down. Finally, the power output of the clamping cylinder 109 is released, causing the upper crossbar 102 to separate from the lower crossbar 101, the top baffle plate 108 to detach from the top of the goods, and the forklift is controlled to move so that the insert arm 107 is pulled out from the bottom of the pallet, completing the separation of the pallet and the goods. Specific Implementation Example 2 Please see Figure 1 , Figure 4 , Figure 5 and Figure 6Based on the first specific embodiment, the pushing assembly 200 includes a scissor telescopic mechanism 201 fixedly connected to the front of a plurality of first fixed uprights 105. The movable end of the scissor telescopic mechanism 201 is fixedly connected to a pushing frame 202 for pushing goods. The back of the pushing frame 202 is provided with an ejector 203 for adjusting the length of the pushing frame 202. The scissor telescopic mechanism 201 has the characteristics of large telescopic stroke and strong load-bearing capacity, which can drive the pushing frame 202 to extend stably and push the goods from the insert arm 107 to the target position. The ejector 203 can adjust the length of the pushing frame 202 so that the pushing frame 202 can be adapted to goods of different lengths.

[0031] Specifically, the pusher frame 202 includes multiple first crossbars 202a equidistantly fixed to the movable end of the scissor telescopic machine 201. Second crossbars 202d are movably sleeved inside each of the multiple first crossbars 202a. Second longitudinal bars 202c are orthogonally fixed to the outside of the multiple second crossbars 202d. Second sliding longitudinal bars 202i are slidably connected inside the second longitudinal bars 202c. Multiple first longitudinal bars 202b are equidistantly fixed to the front of the multiple first crossbars 202a. First sliding longitudinal bars 202g are movably sleeved inside each of the multiple first longitudinal bars 202b. Top crossbars 202e are fixedly connected to the front of the multiple first sliding longitudinal bars 202g. Top sliding bars 202f are movably sleeved inside the top crossbars 202e. 2f is fixedly connected to the outside of the second sliding vertical bar 202i. The back of multiple first horizontal bars 202a is fixedly connected to an electric telescopic rod 202h, and the output end of the electric telescopic rod 202h is fixedly connected to the outside of the top horizontal bar 202e. The pusher 202 forms a multi-directional adjustable frame structure through multiple sets of movable connections between the first horizontal bar 202a and the second horizontal bar 202d, the first vertical bar 202b and the first sliding vertical bar 202g, the second vertical bar 202c and the second sliding vertical bar 202i, and the top horizontal bar 202e and the top sliding rod 202f. The electric telescopic rod 202h can drive the top horizontal bar 202e to move related components, realizing flexible adjustment of the overall height of the pusher 202, which can adapt to goods of different sizes.

[0032] Furthermore, the two ejectors 203 include two sliding sleeves 203a that are respectively fixedly connected to the back of the top crossbar 202e and the first crossbar 202a. An ejector rod 203b is movably sleeved inside each of the two sliding sleeves 203a, and one end of each ejector rod 203b is fixedly connected to the outside of the second sliding vertical bar 202i and the second vertical bar 202c. A retaining ring 203c is fixedly connected to the outside of each of the two ejector rods 203b, and a spring 203d for pushing the retaining ring 203c is movably sleeved on the outside of each of the two ejector rods 203b. The ejector 203 uses the elastic force of the spring 203d to push the retaining ring 203c, causing the ejector rod 203b to slide along the sliding sleeve 203a, thereby pushing the second sliding vertical bar 202i and the second vertical bar 202c to move, thus assisting in adjusting the length of the pusher frame 202.

[0033] The operation process of this embodiment is as follows: When it is necessary to push the goods, firstly, according to the length and height of the goods, start the electric telescopic rod 202h. Its output end pushes the top crossbar 202e to move, causing the first sliding vertical rod 202g to slide along the inside of the first vertical rod 202b. At the same time, the top sliding rod 202f slides along the inside of the top crossbar 202e, and the second sliding vertical rod 202i slides along the inside of the second vertical rod 202c. Adjust the overall height of the pusher 202 until the pusher 202 matches the height of the goods. At this time, the spring 203d in the ejector 203 pushes the retaining ring 203c through elastic force, causing the ejector rod 203b to slide along the inside of the first vertical rod 202b. The sliding sleeve 203a slides inside, further pushing the second longitudinal bar 202c and the second sliding longitudinal bar 202i to move, so that the second cross bar 202d slides inside the first cross bar 202a to adapt to the length of the goods and ensure that the pusher 202 can fully contact the goods; then confirm that the clamping assembly 100 and the blocking assembly 400 have released the clamping and limiting of the goods, start the scissor telescopic machine 201, and its movable end drives the pusher 202 to extend towards the goods. After the first longitudinal bar 202b and the second longitudinal bar 202c of the pusher 202 contact the side of the goods, they continuously apply a pushing force to smoothly push the goods out from the top of the insert arm 107. Specific Implementation Example 3 This embodiment is the third embodiment of this application. This embodiment provides a material pushing method for a forklift material rotary ejection device, which stacks materials according to the following steps: S1. Move the forklift to the location of the goods to be transported, adjust the position of the forklift so that the two insert arms 107 of the clamping assembly 100 are aligned with the pallet insertion holes at the bottom of the goods, and slowly insert the insert arms 107 into the pallet until the top baffle 108 is close to the back of the goods to complete the initial positioning. At this time, the fixed sliding groove plate 103 and the movable sliding groove plate 104 are in the initial open state to prepare for subsequent clamping. S2. Activate the clamping cylinder 109 inside the fixed sliding groove plate 103. The output end of the clamping cylinder 109 pushes the movable sliding groove plate 104 to slide along the inside of the fixed sliding groove plate 103 via a connecting pin, causing the lower crossbar 101 and the upper crossbar 102 to move closer together. At the same time, the first sliding upright 106 at the bottom of the upper crossbar 102 slides down along the inside of the first fixed upright tube 105 at the top of the lower crossbar 101, so that the top baffle 108 fits tightly against the top of the goods, and works with the insert arm 107 to clamp the goods from the top and bottom, preventing the goods from shifting. S3. Start the adjusting cylinder 407. The adjusting cylinder 407 located at the top front of the first sliding upright 106 pushes the left movable upright 406 to slide down along the inside of the left fixed upright 405. The adjusting cylinder 407 located at the bottom front of the first fixed upright 105 pushes the left fixed upright 405 to move laterally. At the same time, the movable crossbar 402 inside the fixed crossbar 401 extends outward, and the right movable upright 404 slides and adjusts along the inside of the right fixed upright 403. Finally, the fixed side plate 408a and comb plate 408b of the side baffle 408 are close to the side of the goods, and the baffle plate 408c is close to the inside of the goods, blocking the goods from the side and forming all-round protection. S4. Start the drive motor 306 of the rotating component 300. The output end of the drive motor 306 drives the drive gear 307 to rotate. The drive gear 307 meshes with the toothed ring 305 outside the rotating collar 304, causing the rotating collar 304 to rotate around the rotating shaft 303 on the mounting frame 302. The front frame 301 rotates synchronously with the rotating collar 304, thereby driving the clamping component 100 and the goods to rotate 180 degrees. After the rotation is completed, the drive motor 306 is locked in the locked position. At this time, the top baffle 108 lifts the goods. S5. Start the scissor telescopic mechanism 201 of the pushing assembly 200. The movable end of the scissor telescopic mechanism 201 drives the pushing frame 202 to extend towards the goods. The first longitudinal bar 202b, the second longitudinal bar 202c and the top crossbar 202e of the pushing frame 202 work together to push the goods smoothly from the insert arm 107 to the target position. At the same time, the pallet can also be easily removed.
