[0002] Nakajima vending machines, a type of prize vending machine, are a simpler form of large-scale arcade games. They feature merchandise displayed in a transparent box with a controllable robotic arm that grabs the items. Users must manipulate the arm to retrieve their desired items. Originally, they primarily held plush toys and similar stuffed animals, hence the names "claw machine" or "doll claw machine." Because the plush toys are very popular, they are especially popular with children and teenagers. Some vendors have also introduced machines that can grab watches, keychains, toys, or even snacks; however, since the principle is the same, they are all called Nakajima machines.

Detailed Implementation

[0027] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0028] Please refer to Figures 1-4 The image shows a schematic diagram of the overall structure of the rotating crane on the central island.

[0029] This embodiment provides a rotating crane structure for a central island crane, including:

[0030] The rotating assembly 1 includes a fixing member 11, a rotating shaft 12, a rotary motor 13, and a rotating member 14. The fixing member 11 is used to fix it in the middle island machine 4; the rotating shaft 12 is rotatably inserted through the fixing member 11 and one end of it is connected to the output shaft of the rotary motor 13; the rotating member 14 is connected to the rotating shaft 12.

[0031] The transverse assembly 2 includes a set of track rods 21, a set of travel wheels, a mounting plate 22, and a transverse motor 23. The set of track rods 21 is connected to the rotating component 14. The set of travel wheels is slidably mounted on the set of track rods 21 and driven by the transverse motor 23. The transverse motor 23 is mounted on the mounting plate 22.

[0032] The lifting assembly 3 includes a lifting claw 31, a lifting rope 32, a lifting rope motor 33, and a pulley mechanism 34. The lifting rope motor 33 is mounted on the mounting plate 22, and the pulley mechanism 34 is rotatably connected to the mounting plate 22 and is drivenly connected to the output end of the lifting rope motor 33. One end of the lifting rope 32 is fixedly threaded through the mounting plate 22, and the other end is wound around the pulley mechanism 34 and then connected to the lifting claw 31.

[0033] The following will further describe a rotating crane structure 00 for an island machine according to this exemplary embodiment.

[0034] In some embodiments, the aforementioned rotating assembly 1 includes a fixing member 11, a rotating shaft 12, a rotary motor 13, and a rotating component 14. The fixing member 11 is used to fix the crane structure 00 inside the island machine 4, specifically by installing it on the inner wall of the island machine 4. The rotating shaft 12 rotatably passes through the fixing member 11, and one end of it is connected to the output shaft of the rotary motor 13; the rotating component 14 is connected to the rotating shaft 12. The rotating shaft 12 is driven to rotate by the rotary motor 13, which in turn drives the rotating component 14 to rotate. The rotating component 14 then drives the transverse moving assembly 2 and the lifting assembly 3 to rotate synchronously, performing rotational motion. By controlling the rotary motor 13, the rotation angle and rotation direction can be controlled, thereby achieving the adjustment of the position of the lifting claw 31 moving back and forth inside the island machine 4.

[0035] In some embodiments, the aforementioned lateral movement assembly 2 includes a set of track rods 21, a set of travel wheels, a mounting plate 22, and a lateral movement motor 23. The set of track rods 21 is connected to the rotating component 14, and the set of travel wheels is slidably mounted on the set of track rods 21 and driven by the lateral movement motor 23. The lateral movement motor 23 is mounted on the mounting plate 22. That is, the lateral movement motor 23 drives the set of travel wheels to move horizontally along the set of track rods 21. By controlling the lateral movement motor 23, the moving speed and distance can be adjusted, thereby adjusting the position of the lifting claw 31 to move left and right. Combined with the rotational action, this achieves omnidirectional movement of the lifting claw 31 on the horizontal plane.

[0036] In some embodiments, the lifting assembly 3 includes a lifting claw 31, a lifting rope 32, a lifting rope motor 33, and a pulley mechanism 34. The lifting rope motor 33 is mounted on the mounting plate 22, and the pulley mechanism 34 is rotatably connected to the mounting plate 22 and driven by the output end of the lifting rope motor 33. One end of the lifting rope 32 is fixedly threaded through the mounting plate 22, and the other end is wound around the pulley mechanism 34 and connected to the lifting claw 31. That is, by driving the pulley mechanism 34 to rotate through the lifting rope motor 33, the lifting rope 32 can be wound around the pulley mechanism 34 or released, thereby realizing the lifting and lowering of the lifting rope 32, which in turn drives the lifting claw 31 to lift and lower, achieving longitudinal movement.

[0037] It should be noted that the aforementioned transverse motor 23 and rope motor 33 can be connected by a worm gear structure to drive the travel wheel group to move and drive the pulley mechanism 34 to rotate, respectively.

[0038] In a preferred embodiment, the aforementioned fixing member 11 is U-shaped, comprising a first plate disposed opposite to the other two plates and a second plate connected between the two first plates; the second plate is provided with mounting holes for mounting on the side wall of the central island machine 4; the rotating shaft 12 is vertically rotatably inserted through the two first plates. That is, during installation, the fixing member 11 is vertically installed, the two first plates are vertically opposite each other, and the rotating shaft 12 is rotatably inserted through the two first plates. The rotary motor 13 is disposed on the top of the upper first plate and is connected to one end of the rotating shaft 12 for transmission, driving the rotating shaft 12 to rotate, thereby driving the rotating component 14 to rotate.

[0039] In a preferred embodiment, the rotating member 14 is U-shaped, comprising a third plate disposed opposite to the other two third plates and a fourth plate connected between the two third plates; the two third plates are fixedly inserted through the rotating shaft 12; and the track rod 21 group is fixedly connected to the side of the fourth plate away from the second plate. The rotating member 14 is also vertically mounted, disposed opposite to the fixing member 11, with their openings facing each other to facilitate the rotation of the rotating member 14. The track rod 21 group is connected to the outside of the fourth plate, facilitating connection and fixation, and also facilitating the synchronous rotation of the track rod 21 group.

[0040] In a preferred embodiment, an outer frame 15 is provided above the two third plates, and a fixing plate 16 is provided inside the outer frame 15 for mounting the rotary motor 13. The fixing plate 16 is positioned above the first plate and is horizontally aligned with it. The motor is mounted on top of the fixing plate 16 and located inside the outer frame 15 for shielding and protection. The output shaft of the rotary motor 13 extends downward and is connected to the rotating shaft 12 for driving the rotating shaft 12 to rotate. This structural design results in a compact structure and prevents interference between the components.

[0041] In a preferred embodiment, both the first and third plates are triangular in shape, with one vertex forming a circular arc transition; the axis of the rotating shaft 12 is opposite to the center of this circular arc. By setting the plates to a triangular shape, the rotating member 14 can rotate at a larger angle relative to the fixed member 11, and there will be no mutual interference between the two.

[0042] In a preferred embodiment, the aforementioned track rod 21 assembly includes two track rods 21 and a fixed housing 24. The fixed housing 24 is L-shaped, with one side positioned parallel above the two track rods 21 and connected to the outer frame 15. One end of each of the two track rods 21 is fixedly connected to the fourth plate, and the other end is fixedly connected to the other side of the fixed housing 24. The fixed housing 24 is used to fix the two parallel track rods 21 and the outer frame 15, connecting the aforementioned structures into a single unit.

[0043] In a preferred embodiment, the aforementioned travel wheel set includes a drive wheel 25 and multiple driven wheels 26, which are slidably mounted on two track rods 21. Specifically, it may include one drive wheel 25 and four driven wheels 26. The output end of the transverse motor 23 is driven by the drive wheel 25, and the driven wheels 26 are rotatably mounted on the outer wall of the transverse motor 23 or on the mounting plate 22. The mounting plate 22 and the transverse motor 23 are positioned between the two track rods 21. The output end of the transverse motor 23 is driven by the axle of the drive wheel 25, driving the drive wheel 25 to rotate and actively move along the track rod 21. The other three driven wheels 26 rotate synchronously under the drive of the drive wheel 25, assisting its movement along the track rod 21.

[0044] In a preferred embodiment, the pulley mechanism 34 includes a driving pulley 341 and at least one driven pulley 342. The driving pulley 341 is rotatably mounted on the mounting plate 22 and is connected to the output end of the suspension rope motor 33. The driven pulley 342 is rotatably mounted on the mounting plate 22 and offset below the driving pulley 341. The driving pulley 341 is driven to rotate by the suspension rope motor 33 to achieve the contraction and release of the suspension rope 32. The driven pulley 342 guides and assists in the contraction and extension of the suspension rope 32, preventing the suspension rope 32 from getting stuck.

[0045] In a preferred embodiment, a stainless steel cover 35 is provided below the aforementioned track rod 21. The stainless steel cover 35 is located on the outside of the mounting plate 22 and connected to the mounting plate 22. A through hole is provided at the center of the bottom of the stainless steel cover 35 for the hoisting rope 32 to pass through. The stainless steel cover 35 is used to shield and protect the transverse motor 23 and the mounting plate 22, etc., thus providing protection and making the structure more aesthetically pleasing.

[0046] In a preferred embodiment, an elastic top rod cylinder 343 is inserted through the aforementioned through hole, through which the lifting rope 32 passes. This serves to limit and guide the lifting rope 32, ensuring it exits from the center of the bottom of the stainless steel cover 35 and is positioned in the middle, maintaining stable clamping. The mounting plate 22 is also equipped with a rocker arm 344 and two microswitches 345. The rocker arm 344 is inclined below the active pulley 341, and one end of the rocker arm 344 is rotatably connected to the mounting plate 22 via a torsion spring 347. The other end of the rocker arm 344 is rotatably connected to a movable pulley 346. The two microswitches 345 are respectively linked to the rocker arm 344 and the elastic top rod cylinder 343. By providing a rocker arm 344 that can rotate up and down, it can rotate up and down with the movable pulley 346 driven by the lifting rope 32, triggering the corresponding microswitches 345 to output a signal indicating that the lifting claw 31 has reached its vertical position, thereby controlling the start / stop and rotation direction of the lifting rope motor 33. Specifically, when the lifting claw 31 is lowered, the lifting rope 32 is pulled by the gravity of the lifting claw 31, causing the rocker arm 344 to rotate upward, which in turn drives the movable pulley 346 to move upward. At this time, the micro switch 345 at the end of the rocker arm 344 away from the movable pulley 346 is disconnected. When the lifting claw 31 contacts the object, the movable pulley 346 is no longer pulled by the gravity of the lifting claw 31 and returns to its original position under the action of the torsion spring 347. Both micro switches 345 are closed, which is the electrical signal for the lowering to the correct position. After the object is clamped, the hoisting rope motor 33 drives the active pulley 341 to rotate, causing the hoisting rope 32 to rise. At the same time, it drives the movable pulley 346 to move upward, and the rocker arm 344 rotates upward, which in turn disconnects the micro switch 345 linked to it. When the clamped object rises to the top, the elastic push rod cylinder 343 pushes upward, disconnecting the micro switch 345 below. At this time, both micro switches 345 are disconnected, which is the electrical signal that the claw 31 has risen to the position.
