Description

[Technical Field]

[0001] This utility model relates to the field of crane technology for claw machines, and in particular to a crane limiting structure. [Background Technology]

[0002] A crane-style claw machine is a common type of claw machine. Similar to a traditional claw machine, it uses a crane as the grabbing mechanism. The crane typically consists of a grabber suspended from the top and a controller. Players control the crane's movement by operating a joystick on the controller and then pressing a button to make the grabber attempt to grab a plush toy or other prize. Once a plush toy is successfully grabbed, the player can take it home as a prize.

[0003] Traditional claw machine cranes typically have travel limit switches on the outside to restrict the lateral movement of the crane. In order to fix the travel limit switches, additional sheet metal parts are usually required. This not only makes the internal space of the claw machine more cramped, but also increases the production cost. At the same time, the exposed travel limit switches and sheet metal parts also affect the overall aesthetics of the claw machine and reduce its visual appeal to players. [Utility Model Content]

[0004] To address the technical problem of exposed limiting structures on current claw machine cranes, which leads to increased production costs and affects the overall aesthetics, this utility model provides a crane limiting structure.

[0005] To achieve the above objectives, this utility model is implemented by the following technical solution:

[0006] A crane limiting structure is applied to a claw machine. It is characterized by comprising a first base plate and a second base plate, with a lateral translation device connected between the first base plate and the second base plate. The lateral translation device includes a track rod and a moving mechanism mounted above the track rod for moving along the track rod. A limiting member is fixed inside the track rod, and a limiting sensor is provided on the moving mechanism. When the limiting sensor senses the limiting member, the movement stops, thereby limiting the lateral movement range of the lateral translation device.

[0007] By adopting the above technical solution, the limiting component is hidden inside the track rod. Compared with the previous method of installing the limiting switch on the outside of the track rod, there is no need to add extra sheet metal parts to fix the limiting switch, thereby reducing design costs and making the claw machine look better. Secondly, the hidden design of the limiting component also reduces the overall size of the crane and optimizes the internal space of the claw machine.

[0008] As described above, in a crane limiting structure, two track rods are provided, which are installed in parallel between the first base plate and the second base plate. The limiting member is fixed inside both ends of one of the track rods, and the limiting sensor is installed on the same side as the limiting member fixed inside the track rod.

[0009] As described above, in a crane limiting structure, the moving mechanism includes a drive wheel assembly and a first drive motor for driving the drive wheel assembly to rotate.

[0010] As described above, in a crane limiting structure, the drive wheel assembly includes a drive wheel and a driven wheel that is pulsatorically connected to the drive wheel, and the drive wheel is connected to the first drive motor.

[0011] As described above, in a crane limiting structure, a gripping device for gripping objects is installed at the bottom of the lateral translation device. The gripping device includes a jaw and a jaw motor for controlling the jaw to grip and place objects. A motion mechanism for controlling the jaw to move up and down is connected above the jaw.

[0012] As described above, the crane limiting structure includes a motion mechanism comprising a traction rope, a winding wheel, a first pulley, and a second pulley. One end of the traction rope is fixedly wound around the winding wheel, and the other end of the traction rope passes sequentially around the first pulley and the second pulley and is connected to the gripper. The winding wheel is connected to a control motor for controlling its rotation.

[0013] As described above, in a crane limiting structure, both the first base plate and the second base plate are provided with a forward and backward moving device on their sides. The forward and backward moving device is used to control the forward and backward movement of the lateral translation device. The forward and backward moving device includes a slide rail, a sliding component mounted on the slide rail, and a second drive motor that drives the sliding component to slide forward and backward.

[0014] In the overhead crane limiting structure described above, the sliding component includes a sliding wheel and a synchronous wheel, which are connected by a belt, and the sliding wheel is connected to the second drive motor.

[0015] As described above, in a crane limiting structure, the forward and backward moving device is further provided with a limiting mechanism. The limiting mechanism includes a limiting switch and a stop block installed at both ends of the slide rail. The limiting switch is located at both ends of the first base plate. When the limiting switch touches the stop block, the forward and backward moving device stops moving.

[0016] In the crane limiting structure described above, a synchronizing rod is also connected between the first base plate and the second base plate to enable the lateral translation device to move smoothly back and forth.

[0017] Compared with the prior art, the crane limiting structure proposed in this utility model has the following beneficial effects:

[0018] 1. The limiting component and limiting sensor proposed in this utility model, by hiding the limiting component inside the track rod, eliminate the need for additional sheet metal parts to fix the limiting switch compared to the previous method of installing the limiting switch on the outside of the track rod, thereby reducing design costs and making the claw machine look better; secondly, the hidden design of the limiting component also reduces the overall volume of the crane and optimizes the internal space of the claw machine.

[0019] 2. The gripping device proposed in this utility model, through the cooperation of the traction rope, the winding wheel and the pulley, can realize the up and down movement of the gripper with a large stroke in a limited space, making the internal structure of the entire device more compact; at the same time, it can buffer and disperse the impact force and overload force generated when gripping the object, reduce the risk of overload damage to the entire motion mechanism, and improve the safety and reliability of the equipment operation.

Detailed Implementation Methods

[0027] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] Please refer to Figure 1The crane limiting structure described in this specification is applied to a claw machine 100. The claw machine 100 is provided with a control structure 200 for controlling the movement of the crane and a control structure 300 for controlling the grippers on the crane to pick up and put down the dolls. The control structure 200 and the control structure 300 of the claw machine are existing technologies and will not be described in detail here.

[0029] Specific embodiments, combined with Figures 2 to 6 As shown, the technical solution of this utility model is further explained. A crane limiting structure includes a first base plate 1 and a second base plate 2. A lateral translation device 10 is connected between the first base plate 1 and the second base plate 2. The lateral translation device 10 includes a track rod 11 and a moving mechanism 12 installed above the track rod 11 for moving along the track rod 11. A limiting member (not shown in the figure) is fixed inside the track rod 11. A limiting sensor 13 is provided on the moving mechanism 12. When the limiting sensor 13 senses the limiting member, it stops moving to limit the lateral movement range of the lateral translation mechanism 20.

[0030] The limiting component may include, but is not limited to, a magnet or a magnetic metal block, and in this embodiment, a magnet is preferred; the limiting sensor 13 may include, but is not limited to, an inductive proximity switch or a Hall sensor, and in this embodiment, an inductive proximity switch is preferred.

[0031] In this embodiment, the limiting component is hidden inside the track rod. Through the cooperation of the limiting sensor and the limiting component, the movement range of the lateral translation mechanism can be accurately limited. Compared with the previous method of installing the limiting switch on the outside of the track rod, there is no need to add sheet metal parts to fix the limiting switch, thereby reducing design costs and making the claw machine look better. Secondly, the hidden design of the limiting component also reduces the overall volume of the crane and optimizes the internal space of the claw machine.

[0032] Furthermore, as a preferred embodiment of this solution and not a limitation, two track rods 11 are provided, and the two track rods 11 are installed in parallel between the first substrate 1 and the second substrate 2. The limiting member is fixed inside both ends of one of the track rods 11, and the limiting sensor 13 is installed on the same side as the limiting member fixed inside the track rod 11.

[0033] In this embodiment, the two parallel track rods allow the weight and force of the moving mechanism to be distributed more evenly on the track, reducing the risk of track rod deformation and avoiding swaying or deviation of the moving mechanism due to track rod deformation, thereby improving the stability and moving accuracy of the moving mechanism during operation. The limit component and limit sensor are set on the same side, which can avoid interference between the limit sensor and other track rods or other parts of the equipment, thus avoiding misjudgment and achieving more accurate limit control. At the same time, it also helps to reduce the overall size of the overhead crane.

[0034] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the moving mechanism 12 includes a drive wheel assembly 121 and a first drive motor 122 for driving the drive wheel assembly 121 to rotate.

[0035] In a preferred embodiment, the drive wheel assembly 121 includes a drive wheel 1211 and a driven wheel 1212 that is pulverizedly connected to the drive wheel 1211. The drive wheel 1211 is connected to the first drive motor 122.

[0036] Specifically, when the lateral translation device 10 needs to move, the first drive motor 122 will drive the drive wheel 1211 to rotate. When the drive wheel 1211 rotates, it will drive the driven wheel 1212 to rotate coaxially, thereby controlling the movement of the lateral translation device 10.

[0037] It should be noted that the coaxial rotation of the driven wheel 1212 driven by the driving wheel 1211 is achieved by means of a coupling.

[0038] Alternatively, the first drive motor 122 may be, but is not limited to, a servo motor or a stepper motor; this embodiment does not specifically limit this.

[0039] In this embodiment, the coaxial rotation of the driving wheel and the driven wheel avoids swaying or deviation caused by uneven power transmission, ensuring that the lateral translation device can operate smoothly during movement. Secondly, the driving wheel and the driven wheel work together on the track rod, increasing the contact area and friction with the track rod, improving the traction and grip of the drive wheel assembly on the lateral translation device, and preventing slippage during movement.

[0040] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the bottom of the lateral translation device 10 is equipped with a gripping device 20 for gripping items. The gripping device 20 includes a gripper 21 and a gripper motor 22 for controlling the gripper 21 to grip and place items. A motion mechanism 23 for controlling the up and down movement of the gripper 21 is connected above the gripper 21.

[0041] The items mentioned may include, but are not limited to, dolls and gift boxes. The specific items can be adjusted according to the actual application scenario. For example, if this application is used on a claw machine, then the items are dolls. Other application scenarios can be implemented based on this reference, and will not be elaborated further here.

[0042] In a preferred embodiment, the motion mechanism 23 includes a traction rope 231, a winding wheel 232, a first pulley 233, and a second pulley 234. One end of the traction rope 231 is fixedly wound around the winding wheel 232, and the other end of the traction rope 231 passes sequentially around the first pulley 233 and the second pulley 234 and is connected to the gripper 21. The winding wheel 232 is connected to a control motor 235 for controlling its rotation, so that the traction rope 231 is tightened or loosened.

[0043] Alternatively, the control motor 242 may include, but is not limited to, a drive motor, a servo motor, or a stepper motor, and the gripper motor 22 may include, but is not limited to, a drive motor or a servo motor.

[0044] Specifically, when the gripper 21 needs to be lowered to grab an item, the control motor 235 will control the winding wheel 232 to rotate clockwise. When the winding wheel 232 rotates clockwise, the traction rope 231 wound on the winding wheel 232 will be gradually released, so that the traction rope 231 is in a slack state. At this time, the gripper 21 will generate a downward traction force due to its own weight. As the traction rope 231 is gradually released, and under the action of the first pulley 233 and the second pulley 234, it will gradually be lowered.

[0045] When the gripper 21 needs to rise, the control motor 235 will control the winding wheel 232 to rotate counterclockwise. When the winding wheel 232 rotates counterclockwise, the traction rope 231 will gradually wind around the winding wheel 232, so that the traction rope 231 is in a taut state. At this time, the gripper 21 will gradually rise due to the upward traction force brought by the taut traction rope 231, and under the action of the first pulley 233 and the second pulley 234.

[0046] In this embodiment, by cooperating with the traction rope, winding wheel, and pulley, the gripper can achieve a large vertical movement within a limited space, making the internal structure of the entire device more compact. At the same time, it can buffer and disperse the impact and overload force generated when gripping items, reduce the risk of overload damage to the entire motion mechanism, and improve the safety and reliability of the device operation.

[0047] Furthermore, as a preferred embodiment of this solution and not a limitation, both the first substrate 1 and the second substrate 2 are provided with a front-to-back moving device 30 on their sides. The front-to-back moving device 30 is used to control the front-to-back movement of the lateral translation device 10. The front-to-back moving device 30 includes a slide rail 31, a sliding component 32 mounted on the slide rail 31, and a second drive motor 33 that drives the sliding component 32 to slide back and forth.

[0048] In a preferred embodiment, the sliding assembly 32 includes a sliding wheel 321 and a synchronous wheel 322, which are connected by a belt 323. The sliding wheel 321 is connected to the second drive motor 33.

[0049] Alternatively, the second drive motor 33 may include, but is not limited to, a drive motor, a servo motor, or a stepper motor.

[0050] In this embodiment, the forward and backward moving device, the lateral translation device, and the gripping device work in coordination to achieve coordinated movement in three-dimensional space, allowing the gripper to move freely within a specified space, making it convenient for players to control and play. Secondly, the cooperation of the slide rail and sliding component provides a stable linear motion path for the lateral translation device, reducing swaying and offset during movement, and ensuring that the lateral translation device can move smoothly forward and backward.

[0051] Furthermore, as a preferred embodiment of this solution and not a limitation, the forward and backward moving device 30 is also provided with a limiting mechanism 34. The limiting mechanism 34 includes a limiting switch 341 and a stop block 342 installed at both ends of the slide rail 31. The limiting switch 341 is disposed at both ends of the first base plate 1. When the limiting switch 341 touches the stop block 342, the forward and backward moving device 30 stops moving.

[0052] In this embodiment, the combination of limit switches and stops can effectively prevent the forward and backward moving devices from exceeding their movement range, thus avoiding equipment damage or safety accidents to players due to overtravel. Secondly, through precise limit control, positional deviations caused by excessive movement of the forward and backward moving devices are avoided, ensuring the overall motion accuracy of the equipment.

[0053] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, a synchronizing rod 40 is also connected between the first substrate 1 and the second substrate 2 so that the lateral translation device 10 can move smoothly back and forth.

[0054] In this embodiment, the synchronizing rod 40 can prevent the lateral translation device from swaying or deviating during its forward and backward movement, ensuring that it always maintains a stable linear motion. Secondly, the synchronizing rod can ensure that the first substrate and the second substrate remain synchronized during their forward and backward movement, preventing the lateral translation device from jamming, twisting, or wearing due to asynchronous movement between the substrates, which would cause instability when the gripping device grabs items and result in a poor gaming experience for the player.

[0055] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, both the lateral translation device 10 and the front-to-back movement device 30 are provided with protective housings on their outer sides.

[0056] In this embodiment, the protective housing effectively prevents operators from accidentally coming into contact with moving parts, thus preventing accidents such as pinching or impact injuries, and provides reliable safety protection. Secondly, it also prevents external impurities such as dust from entering the interior of the moving parts, avoiding problems such as jamming or wear of the moving parts, reducing the failure rate, and extending the service life of the equipment.

[0057] The working principle of this utility model is as follows:

[0058] This utility model proposes a crane limiting structure for use in claw machines. Through the concealed design of the limiting component, the overall size and design cost of the crane are reduced, and the appearance of the claw machine is also improved. Specifically:

[0059] When the player manipulates the horizontal translation device 10 to move horizontally, the moving mechanism 12 will move horizontally along the track rod 11. During the movement, if the limit sensor 13 of the moving mechanism 12 detects a limit member installed inside the track rod 11, the movement will stop. For example, when the player manipulates the horizontal translation device 10 to move to the left, if the limit sensor 13 of the moving mechanism 12 detects a limit member installed inside the left end of the track rod 11, the movement will stop to prevent the horizontal translation device 10 from continuing to move to the left. Similarly, the same applies when moving to the right.

[0060] Those skilled in the art should understand that the above description is one embodiment provided in conjunction with specific content, and does not imply that the specific implementation of this utility model is limited to these descriptions. Furthermore, due to differences in industry naming conventions, it is not limited to the above names or English names. Any methods or structures similar to or identical to those of this utility model, or any technical deductions or substitutions made based on the concept of this utility model, should be considered within the scope of protection of this utility model.
