Description

Technical Field

[0001] The present invention relates to the technical field of material stacking, and particularly relates to a fork for coil materials and a stacking machine. Background Art

[0002] In the existing three-dimensional warehouse storage, a movable stacking machine is used for stacking. When the existing conventional stacking machine transports coil materials, the coil materials need to be placed on a tray first and then turned into the three-dimensional warehouse for storage. The following problems exist during the operation: 1. When the coil materials are placed vertically on the tray, they are prone to deformation, resulting in material damage. When the stacking machine accelerates and decelerates too quickly, the coil materials may slide or fall over; 2. The size of the tray is fixed, and small-sized types are also placed on the standard-sized tray, resulting in a small utilization rate of the space in the three-dimensional warehouse.

[0028] Embodiment 1:

[0029] Please refer to Figure 1 - Figure 2 , a roll material fork 5, including: a fork arm 51;

[0030] It includes a mounting part 52, a drive mechanism 54 and two support mechanisms 53. The support mechanism 53 is a parallelogram structure, and the mounting part 52 carries the drive mechanism 54 and is installed below the fork arm 51;

[0031] The two supporting mechanisms 53 each include a connecting ear 531, a first connecting member 532, a second connecting member 533 and a stabilizing arm 534. The first connecting member 532 and the second connecting member 533 are both rotatably connected to the connecting ear 531, and the first connecting member 532 and the second connecting member 533 are both rotatably connected to the stabilizing arm 534.

[0032] The driving mechanism 54 includes a first linear driving component 541 and a driving swing arm 542 installed on the mounting member 52. The supporting mechanism 53 is installed on the first linear driving component 541 and moves with it. The driving swing arm 542 is rotationally connected to the mounting member 52 and the supporting mechanism 53. The stabilizing arm 534 in the supporting mechanism 53 is opened or closed by the approach and distance of the supporting mechanism 53 to the driving swing arm 542.

[0033] Working principle:

[0034] When in use, the roll material fork 5 is inserted into the inner hole of the roll material so that the roll material is hung on the fork arm 51, and then the support mechanism 53 drives the swing arm 542 to approach or move away, driving the stabilizing arm 534 in the support mechanism 53 to open and fit the inner wall of the roll material, thereby effectively maintaining the stability of the roll material during movement.

[0035] Specifically, the first linear driving component 541 is a screw nut pair, and the two supporting mechanisms 53 are symmetrically installed on both sides of the nut of the screw nut pair; the driving swing arm 542 is rotatably installed at the far end of the screw nut pair.

[0036] When in use, the motor-driven nut of the screw-nut pair carries the support mechanism 53 to move toward the distal end on the screw, because the driving swing arm 542 is rotationally 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 driving swing arm 542 during the movement.

[0037] Further, the connecting line a between the beginning and the end of the first connecting member 532 and the connecting line a between the beginning and the end of the second connecting member 533 are parallel and identically arranged; the connecting point between the second connecting member 533 and the driving swing arm 542 is set as the driving point 56, and the driving point 56 is set away from the connecting line a55;

[0038] By deviating the driving point 56 from the connecting line a55, the supporting mechanism 53 can be effectively driven by the driving swing arm 542 when moving, thereby avoiding the situation in which the driving swing arm 542 overlaps with the connecting line a55 of the second connecting member 533 and causes the device to be stuck.

[0039] Embodiment 2:

[0040] See also Figure 1 - Figure 4A stacker includes the roll material fork 5, the support column 1, the bearing platform 3, and a lifting mechanism 4 for driving the bearing platform 3 to rise and fall in the first embodiment. The bearing platform 3 is slidably installed on the support column 1, and the roll material fork 5 is installed on the bearing 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 roll material fork 5 is slidably installed on the upper surface of the support plate 33 through a slide rail 34, and a second linear driving component 35 for driving the fork arm 51 to slide on the support plate 33 is installed on the support plate 33.

[0042] Mounting frames 36 are provided on both sides of the carrier frame 31 , and both mounting frames 36 are slidably connected to the supporting column 1 through rollers installed on the outside.

[0043] The lifting mechanism 4 includes a driving motor 41, a drum 42, a wire rope 43, and a fixed pulley 44. The driving motor 41 carries the drum 42 and is installed on the supporting column 1. The top of the supporting column 1 is fixedly connected through the crossbeam 2. The fixed pulley 44 is installed on the top of the crossbeam 2. The wire rope 43 is wound around the drum 42 and passes around the fixed pulley 44 on the top of the supporting column 1 and is connected to the supporting platform 3.

[0044] The carrier frame 31 is installed at the center of the carrier platform 3 through the slewing bearing 32 , and the diameter of the slewing bearing 32 carrying the carrier frame 31 to rotate on the carrier platform 3 is smaller than the distance between the two mounting frames 36 ; the top view length of the fork arm 51 is smaller than the length of the carrier plate 33 .

[0045] A bottom beam is provided at the bottom of the support column 1, and a self-propelled mechanism is provided on the bottom beam, such as a self-propelled mechanism in the prior art that starts a roller wheel by a motor and moves on a track.

[0046] Working principle:

[0047] When the rolled material is hung on the fork arm 51, the motor-driven nut of the screw nut pair carries the support mechanism 53 to move toward the far end on the screw, because the driving swing arm 542 is rotatably connected with the second connecting member 533 in the support mechanism 53, and the support mechanism 53 opens the stabilizing arm 534 under the push of the driving swing arm 542 during the movement, thereby effectively maintaining the stability of the rolled material during the movement;

[0048] Then the driving motor 41 in the lifting mechanism 4 is started, so that the winding drum 42 winds up the wire rope 43 to pull the supporting platform 3 to rise and fall, that is, the roll material fork 5 located on the supporting platform 3 carries the roll material to a suitable position, and then the fork arm 51 carries the roll material out of the range of the supporting platform 3 through the second linear driving component 35, so as to facilitate the removal of the roll material from the roll material fork 5; its second linear driving component 35 can be a motor carrying a gear to move on the rack.

[0049] Further, the fork arm 51 includes an L-shaped structure composed of a mounting arm 511 and a bearing arm 512. The mounting arm 511 is vertically installed on the upper surface of the bearing plate 33 through the slide rail 34. The top and bottom of the bearing arm 512 form a bearing space, and the setting of the bearing space can be used to adapt to the thickness of the roll-like material.

[0050] The above are only the embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, various changes and modifications can be made to the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the scope of the claims of the present invention.
