Abstract
Description
Technical Field
[0001] This utility model relates to the field of material stacking technology, specifically to a coil material fork and stacker. Background Technology
[0002] In existing automated warehouse storage systems, mobile stacker cranes are used for stacking. When transporting roll materials, conventional stacker cranes require the rolls to be placed on pallets before being flipped into the automated warehouse for storage. The following problems exist during operation: 1. Roll materials placed vertically on pallets are prone to deformation and damage. When the stacker crane accelerates or decelerates too quickly, the rolls may slide or tip over; 2. The pallet size is fixed, and even small-sized items are placed on standard-sized pallets, resulting in low space utilization in the automated warehouse. Utility Model Content
[0003] To address the shortcomings of existing technologies, a coil-type material fork includes: fork arms;
[0004] It includes a mounting component, a drive mechanism, and two support mechanisms. The support mechanisms are parallelogram structures, and the mounting component carries the drive mechanism and is mounted below the fork arm.
[0005] Both of the aforementioned support mechanisms include a connecting ear, a first connecting member, a second connecting member, and a stabilizing arm. The beginning ends of the first connecting member and the second connecting member are rotatably connected to the connecting ear, and the ends of the first connecting member and the second connecting member are rotatably connected to the stabilizing arm.
[0006] The drive mechanism includes a first linear drive component and a drive swing arm mounted on the mounting component. The support mechanism is mounted on the first linear drive component and moves accordingly. The drive swing arm is rotatably connected to the mounting component and the support mechanism. The support mechanism moves closer to or further away from the drive swing arm, causing the stabilizing arm in the support mechanism to open or close.
[0007] The first linear drive component is a lead screw and nut pair, and the two support mechanisms are symmetrically installed on both sides of the nut of the lead screw and nut pair.
[0008] The line a connecting the beginning and end of the first connector is parallel and identical to the line a connecting the beginning and end of the second connector.
[0009] The connection point between the second connector and the drive swing arm is set as the drive point, and the drive point is offset from the connection line a.
[0010] A stacker crane includes a coil material fork, a support column, a support platform, and a lifting mechanism for driving the lifting of the support platform, wherein the support platform is slidably mounted on the support column and the coil material fork is mounted on the support platform.
[0011] The support platform includes a support frame, a support plate is installed in the center of the support frame, the fork arms of the coiled material fork are slidably mounted on the upper surface of the support plate via slide rails, and a second linear drive component for driving the fork arms to slide on the support plate is installed on the support plate.
[0012] The support frame is equipped with mounting brackets on both sides, and both mounting brackets are slidably connected to the support column via rollers installed on the outer side.
[0013] The lifting mechanism includes a drive motor, a drum, a wire rope, and a fixed pulley. The drive motor carries the drum and is installed on the support column. The top of the support column is fixedly connected by a crossbeam. The fixed pulley is installed on the top of the crossbeam. The wire rope is wound around the drum and passes over the fixed pulley at the top of the support column before connecting to the support platform.
[0014] The support frame is installed in the center of the support platform by a slewing bearing, and the diameter of the slewing bearing carrying the support frame to rotate on the support platform is smaller than the distance between the two mounting frames.
[0015] The top-view length of the fork arm is less than the length of the support plate.
[0016] The fork arm includes an L-shaped structure consisting of a mounting arm and a support arm, wherein the mounting arm is vertically mounted on the upper surface of the support plate via a slide rail.
[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0018] In use, the forks of this invention extend into the inner hole of the rolled material, and then the stabilizing arm in the support mechanism opens to fit against the inner wall of the rolled material for support, thereby effectively maintaining the stability of the rolled material during movement. This solves the problems of existing pallet-compatible forks being prone to deformation when transferring rolled materials, and the fixed pallet size, which means that even small-sized materials are placed on standard-sized pallets, resulting in low space utilization in automated warehouses.

[0028] Example 1:
[0029] Please see Figures 1-2 A type of fork for rolling materials 5, comprising: fork arms 51;
[0030] It includes a mounting component 52, a drive mechanism 54, and two support mechanisms 53. The support mechanism 53 has a parallelogram structure. The mounting component 52 carries the drive mechanism 54 and is mounted below the fork arm 51.
[0031] Both support mechanisms 53 include a connecting ear 531, a first connecting member 532, a second connecting member 533, and a stabilizing arm 534. The beginning ends of the first connecting member 532 and the second connecting member 533 are rotatably connected to the connecting ear 531, and the ends of the first connecting member 532 and the second connecting member 533 are rotatably connected to the stabilizing arm 534.
[0032] The drive mechanism 54 includes a first linear drive component 541 and a drive swing arm 542 mounted on the mounting component 52. The support mechanism 53 is mounted on the first linear drive component 541 and moves with it. The drive swing arm 542 is rotatably connected to the mounting component 52 and the support mechanism 53. The support mechanism 53 moves closer to and further away from the drive swing arm 542, causing the stabilizing arm 534 in the support mechanism 53 to open or close.
[0033] Working principle:
[0034] When in use, the fork 5 for rolling materials extends into the inner hole of the rolling material, causing the rolling material to hang on the fork arm 51. Then, through the support mechanism 53, the stabilizing arm 534 in the support mechanism 53 opens to fit against the inner wall of the rolling material as the support mechanism moves closer to or further away from the drive swing arm 542, thereby effectively maintaining the stability of the rolling material during movement.
[0035] Specifically, the first linear drive component 541 is a lead screw and nut pair, and two support mechanisms 53 are symmetrically installed on both sides of the nut of the lead screw and nut pair; the drive swing arm 542 is rotatably installed at the far end of the lead screw and nut pair.
[0036] In use, the motor of the lead screw and nut pair drives the nut to move the support mechanism 53 to the far end on the lead screw. Because the drive arm 542 is rotatably connected to the second connecting piece 533 in the support mechanism 53, and the support mechanism 53 will open the stabilizing arm 534 under the push of the drive arm 542 during the movement.
[0037] Furthermore, the line a connecting the beginning and end of the first connector 532 is parallel and equivalent to the line a connecting the beginning and end of the second connector 533; the connection point between the second connector 533 and the drive swing arm 542 is set as the drive point 56, and the drive point 56 is offset from the connecting line a55.
[0038] By offsetting the drive point 56 from the connecting line a55, the support mechanism 53 can be effectively driven by the drive arm 542 when moving, thus avoiding the situation where the drive arm 542 and the connecting line a55 of the second connector 533 overlap, which could cause the equipment to jam.
[0039] Example 2:
[0040] Please see Figures 1-4A stacker crane includes a roll material fork 5, a support column 1, a support platform 3 as described in Embodiment 1, and a lifting mechanism 4 for driving the support platform 3 to rise and fall. The support platform 3 is slidably mounted on the support column 1, and the roll material fork 5 is mounted on the support platform 3.
[0041] The support platform 3 includes a support frame 31, a support plate 33 is installed in the center of the support frame 31, the fork arm 51 of the coil material fork 5 is slidably mounted on the upper surface of the support plate 33 via a slide rail 34, and a second linear drive component 35 for driving the fork arm 51 to slide on the support plate 33 is installed on the support plate 33.
[0042] The support frame 31 has mounting brackets 36 on both sides, and both mounting brackets 36 are slidably connected to the support column 1 through rollers installed on the outer side.
[0043] The lifting mechanism 4 includes a drive motor 41, a drum 42, a wire rope 43, and a fixed pulley 44. The drive motor 41 carries the drum 42 and is mounted on the support column 1. The top of the support column 1 is fixedly connected through a crossbeam 2. The fixed pulley 44 is mounted on the top of the crossbeam 2. The wire rope 43 is wound around the drum 42 and passes around the fixed pulley 44 at the top of the support column 1 before being connected to the support platform 3.
[0044] The support frame 31 is mounted in the center of the support platform 3 via a slewing bearing 32, and the diameter of the slewing bearing 32 carrying the support frame 31 to rotate on the support platform 3 is smaller than the distance between the two mounting brackets 36; the top view length of the fork arm 51 is smaller than the length of the support plate 33.
[0045] The support column 1 has a bottom beam at its bottom, and a self-propelled mechanism is provided on the bottom beam, such as a self-propelled mechanism that moves on a track by starting rollers with a motor, which is a conventional self-propelled mechanism.
[0046] Working principle:
[0047] When the rolled material is hung on the fork arm 51, the motor of the screw nut pair drives the nut to carry the support mechanism 53 to move to the far end on the screw. Because the drive swing arm 542 is rotatably connected to the second connecting piece 533 in the support mechanism 53, and the support mechanism 53 will open the stabilizing arm 534 under the push of the drive swing arm 542 during the movement, the stability of the rolled material is effectively maintained during the movement.
[0048] Then the drive motor 41 in the lifting mechanism 4 starts, causing the winding drum 42 to wind up the wire rope 43 and pull the support platform 3 to rise and fall. That is, the fork 5 of the rolled material on the support platform 3 carries the rolled material to a suitable position. Then, the second linear drive component 35 causes the fork arm 51 to carry the rolled material out of the range of the support platform 3, so as to facilitate the removal of the rolled material from the fork 5. The second linear drive component 35 can be a motor carrying a gear that moves on a rack.
[0049] Furthermore, the fork arm 51 includes an L-shaped structure consisting of a mounting arm 511 and a bearing arm 512. The mounting arm 511 is vertically mounted on the upper surface of the bearing plate 33 via the slide rail 34. The top and bottom of the bearing arm 512 form a bearing space, which can be used to adapt to the thickness of rolled materials.
[0050] The above are merely embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
