Description

Technical Field

[0001] This invention relates to a vending machine for selecting items, and more particularly to a cord buffer mechanism for a vending machine for selecting items. Background Technology

[0002] A claw machine, also known as a prize vending machine, is an electronic game machine. Its common structure includes a transparent box displaying prizes and a robotic arm positioned above the transparent box to hold the prizes inside. A typical robotic arm mainly consists of a cable winding device and a gripper device. The cable winding device is connected to the gripper device via a control cable to control the lifting, lowering, and placing of the gripper.

[0003] However, since the displacement of the robotic arm and the operation of the gripper device inevitably cause shaking, the control lines are prone to breakage and the related structures are prone to deformation, so there is a real need for improvement. Summary of the Invention

[0004] Therefore, the object of the present invention is to provide a winding buffer mechanism for a vending machine to solve the problems of the prior art.

[0005] The present invention provides a cable winding buffer mechanism for a vending machine to solve the problems of the prior art. The mechanism is installed in a cable winding device of the vending machine. The cable winding device has a base and a winding wheel, a first pulley, a second pulley, and a cable guide tube disposed on the base. A control cable passes sequentially from the winding wheel around the first pulley and the second pulley and extends through the cable guide tube, so that the winding and unwinding of the control cable is controlled by the winding wheel. The cable winding buffer mechanism includes: a rotating plate having a pivot end and a pivoting end. The pivot end is pivotally connected to the base in a pivoting manner relative to the pivot end. The first pulley is disposed at the pivoting end. A reset member is connected between the rotating plate and the base, applying a reset force to the pivoting end to return it to an initial pivoting position, thereby providing buffering for the pivoting movement of the rotating plate and reducing the vibration of the control cable during operation of the cable winding device.

[0006] In one embodiment of the present invention, a winding buffer mechanism is provided, wherein the reset member is an elastic member and the reset force is an elastic restoring force.

[0007] In one embodiment of the present invention, a winding buffer mechanism is provided, wherein the reset member is a tension spring configured to provide an elastic restoring force that pulls the pivot end back to the initial pivot position when the pivot end pivots away from the initial pivot position.

[0008] In one embodiment of the present invention, a winding buffer mechanism is provided, further comprising a buffer block disposed on the base in such a manner as to a buffer abutment position corresponding to the pivot end, and abutting the rotating plate when the pivot end of the rotating plate pivots from the initial pivot position to the buffer abutment position, so as to provide buffering to the rotating plate.

[0009] In one embodiment of the present invention, a winding buffer mechanism is provided, further comprising a buffer elastic member, wherein the buffer block is elastically connected to the base via the buffer elastic member, so that when the rotating plate abuts against the buffer block, the elastic restoring force of the buffer elastic member provides buffering for the buffer block and the rotating plate.

[0010] In one embodiment of the present invention, a winding buffer mechanism is provided, wherein the buffer elastic member is a tension spring.

[0011] In one embodiment of the present invention, a winding buffer mechanism is provided, further comprising a pivot slider and a pivot guide rail. The pivot slider is disposed on the rotating plate, and as the rotating plate pivots, the pivot guide rail extends on the base in a manner corresponding to the pivot path of the pivot slider. The pivot slider slides on the pivot guide rail to guide the pivot movement of the rotating plate.

[0012] Through the technical means adopted in this invention, the winding buffer mechanism of the vending machine of this invention can apply a pivoting reset force to the rotating plate by means of the reset member, so that the first pulley set on the rotating plate provides appropriate tension to the control line, thereby suppressing the vibration of the control line and effectively improving various problems caused by vibration that the control line is prone to breakage and related structures are prone to deformation.

Detailed Implementation

[0015] The following is based on Figures 1 to 3 This description illustrates one embodiment of the present invention. It is not intended to limit the scope of the invention, but rather to provide one possible embodiment.

[0016] like Figures 1 to 3 As shown, a winding buffer mechanism 2 of a vending machine according to an embodiment of the present invention is provided in a winding device 1 of the vending machine. The winding device 1 has a base 11 and a winding wheel 12, a first pulley 13, a second pulley 14 and a cable guide tube 15 disposed on the base 11. A control cable 16 is provided to pass through the winding wheel 12, sequentially around the first pulley 13 and the second pulley 14 and extend through the cable guide tube 15, so that the winding and unwinding of the control cable 16 is controlled by the winding wheel 12.

[0017] like Figures 1 to 3 As shown, the winding buffer mechanism 2 includes a rotating plate 21 and a reset member 22.

[0018] like Figures 1 to 3 As shown, the rotating plate 21 has a pivot end 211 and a pivoting end 212. The pivot end 211 is pivotally connected to the base 11 in a manner that allows the pivoting end 212 to pivot relative to the pivot end 211. The first pulley 13 is disposed on the pivoting end 212. In this way, the first pulley 13 can pivot together with the rotating plate 21 and be used as a movable pulley.

[0019] like Figures 1 to 3 As shown, the reset member 22 is connected between the rotating plate 21 and the base 11, and applies a pivoting initial position to the pivoting end 212. Figure 1 The resetting force 221 of the pivot reset provides a buffer for the pivoting motion of the rotating plate 21, reducing the vibration of the control line 16 during operation of the winding device 1.

[0020] With the above structure, the winding buffer mechanism 2 of the vending machine of the present invention can apply a pivoting reset force 221 to the rotating plate 21 by means of the reset member 22, so that the first pulley 13 provided on the rotating plate 21 provides appropriate tension to the control line 16, thereby suppressing the vibration of the control line 16 and effectively improving various problems such as easy breakage of the control line and easy deformation of related structures caused by vibration.

[0021] Better, such as Figures 1 to 3 As shown, in the cord buffer mechanism 2 of the vending machine according to an embodiment of the present invention, the reset member 22 is an elastic member, and the reset force 221 is an elastic restoring force. Further, the reset member 22 is a tension spring, configured to provide the elastic restoring force to pull the pivot end 212 back to the initial pivot position when the pivot end 212 pivots away from the initial pivot position. Of course, the present invention is not limited thereto; in other embodiments, the reset member 22 may also be a compression spring or other types of elastic members.

[0022] Specifically, such as Figure 2 and Figure 3 As shown, when the winding device 1 controls the winding and unwinding of the control line 16, the first pulley 13 will displace due to the tension of the control line 16, and will pivot together with the rotating plate 21. When the pivoting end 212 of the rotating plate 21 moves away from the initial pivoting position... Figure 1 When the spring is stretched, the reset member 22 (tension spring) will be stretched accordingly. At the same time, the reset member 22 (tension spring) will also provide the elastic restoring force to its free end object (i.e., the rotating plate 21) due to its own elastic deformation.

[0023] like Figure 2 and Figure 3 As shown, according to Hooke's Law, the reset member 22 (tension spring) is located away from the initial position of the pivot ( Figure 1 The farther away the spring is, the greater the elastic restoring force becomes. The elastic restoring force of the reset member 22 (tension spring) can provide appropriate buffering for the pivoting motion of the rotating plate 21, suppress the vibration generated during the motion, and properly tighten the control line 16, thereby reducing both the pivoting motion of the rotating plate 21 and the vibration of the control line 16, thus improving many problems caused by vibration, such as control line breakage and structural deformation.

[0024] Better, such as Figures 1 to 3 As shown, in a vending machine according to an embodiment of the present invention, the winding buffer mechanism 2 further includes a buffer block 231, which is positioned at a buffer abutment position corresponding to the pivot end 212. Figure 3The base 11 is arranged in a manner that allows it to pivot at the pivot end 212 of the rotating plate 21 from the initial pivot position. Figure 1 ) pivot to the buffer abutment position ( Figure 3 When it comes into contact with the rotating plate 21, it provides a cushioning to the rotating plate 21.

[0025] Specifically, by setting the buffer block 231, when the pivot end 212 of the rotating plate 21 pivots to the buffer abutment position (Figure), the buffer block 231 will abut against the rotating plate 21 and provide buffer for the pivot movement of the rotating plate 21, reduce its vibration, and achieve the effect of improving the structural deformation problem caused by vibration.

[0026] Better, such as Figures 1 to 3 As shown, in the cord buffer mechanism 2 of the vending machine according to an embodiment of the present invention, a buffer elastic member 232 is further included. The buffer block 231 is elastically connected to the base 11 via the buffer elastic member 232, so that when the rotating plate 21 abuts against the buffer block 231, the elastic restoring force of the buffer elastic member 232 provides buffering for the buffer block 231 and the rotating plate 21. Further, the buffer elastic member 232 is a tension spring, which is configured to be stretched when the rotating plate 21 abuts against the buffer block 231, so as to provide buffering by its elastic restoring force.

[0027] Better, such as Figures 1 to 3 As shown, in the winding buffer mechanism 2 of the vending machine in one embodiment of the present invention, a pivot slider 241 and a pivot guide rail 242 are further included. The pivot slider 241 is disposed on the rotating plate 21. As the rotating plate 21 pivots, the pivot guide rail 242 extends and is disposed on the base 11 in a manner corresponding to the pivot path of the pivot slider 241. The pivot slider 241 slides on the pivot guide rail 242 to guide the pivot movement of the rotating plate 21.

[0028] By means of the pivot slider 241 and the pivot guide rail 242, the pivoting motion of the rotating plate 21 can be guided, making the pivoting motion smoother and further reducing the generation of vibration.

Equivalent substitutions or modifications made by those skilled in the art based on this specification are all within the scope of protection of this specification. The scope of protection of this specification is defined by the claims.
