Description

Interactive vending machine switching mechanism

The utility model relates to an interactive vending machine switching mechanism. In particular, the invention relates to a gear that is inserted into the connecting piece by an elastic element, and then the elastic force applied by the elastic element can be smoothly engaged in the phase. An interactive vending machine switching mechanism for adjacent interlocking gears.

As shown in "1" and "2", a conventional interactive vending machine 2, such as a coin machine or a commemorative coin vending machine, is usually provided with an operation dial 21 outside the casing for the user to select. After the commemorative coin pattern is coined and coin-operated, a switching mechanism 22 is actuated to drive a rotary power source (such as an electric motor) to output power and drive through at least one of the drive gears (2211, 2212, ...). The push rod 222 on the drive gear 2212 pushes a push arm 223, and after being pushed, a bridge gear 224 disposed coaxially with the push arm moves toward the meshing position with the other interlocking gears (23, 24, ...). After meshing, the power can be transmitted to the adjacent interlocking gears (23, 24...); however, the teeth of the bridge gear 224 and the teeth of the adjacent interlocking gears (23, 24...) are mutually rimped to each other. When engaged, it may be caused by collision between the teeth, because the teeth themselves wear, or because of large impurities in the slots, causing toothing or even jamming. Phenomenon, at this time, if the rotary power source continues to apply the steering force, it may cause the gear teeth to collapse, and even directly damage the entire mechanical switching mechanism, thereby affecting the transmission operation of the entire vending machine, and even causing unnecessary losses.

Therefore, when the bridge gear is moved to a position where it can mesh with other interlocking gears, how to avoid interference when the bridge gear and the interlocking gear are touched, and thus the toothing phenomenon occurs, so that the bridge gear and the interlocking gear cannot be engaged. It is a problem to be solved.

In view of the above problems, the inventors have studied the related problems based on the switching mechanism of the interactive vending machine for many years, and have studied the foregoing problems; therefore, the main object of the present invention is to provide a way for the bridge gear to move to When it is in a position to mesh with other interlocking gears, it is possible to avoid an "interactive vending machine switching mechanism" in which the bridge gear can be easily engaged with the interlocking gear when the bridge gear is in contact with the interlocking gear.

In order to achieve the above objective, the interactive vending machine switching mechanism of the present invention comprises: a base internally provided with an operating shaft and a transmission shaft extending through the two sides of the base; and a first transmission group including a push arm and a link piece disposed on the shaft, the upper arm of the push arm is provided with an elastic component, a surface of the link piece is formed with a perforation, the through hole is inserted with a bridge gear; and a manual gear is arranged at one end of the operating shaft ( Corresponding to the operation dial operated by the user); a second transmission group comprising a transmission gear and a transmission shaft arranged in a common axis The key of the present invention is that when the push arm is pushed, the linkage piece can be rotated, and the bridge gear is moved toward the meshing position between the manual gear and the transmission gear. When engaged, the elastic element is pressed against the linkage piece. The bridge gear can be elastically biased by the elastic member, and smoothly meshes between the manual gear and the transmission gear, so that the second transmission group can continue to transmit power; accordingly, the present invention does provide a mechanism for moving the bridge gear to be When the other interlocking gears are engaged with each other, the "interactive vending machine switching mechanism" in which the bridge gear can be easily engaged with the interlocking gear can be prevented from being easily interfered when the bridge gear is in contact with the interlocking gear.

Please refer to "Figures 8 and 9" for the implementation of the second embodiment of the present invention (1) and (2). Please refer to "Figure 3" and "Figure 4" together. The second transmission group 14 does not complete the transmission operation of the interactive vending machine within a predetermined time (for example, after the user deposits the coin, the rotating carousel is rotated to the positioning within a limited time, and the coin pressing operation or the conveying operation cannot be completed). That is, the starter motor 151 of the starter motor group 15 is driven to synchronously drive the driven gear 153 to rotate, so that the stud 1531 is away from the position of the push arm 121 that can push the first transmission group 12, so that the push arm 121 and the link piece 122 are moved. During resetting and resetting, the second driving gear 162 on the linking piece 122 moves toward the meshing position with the transmission gear 141, and the bridge gear 1221 on the linking piece 122 is disengaged from the meshing position between the manual gear 13 and the transmission gear 141, such as "Anatar 8"; after the reset, the driving of the starter motor 151 is stopped, and the standby motor 161 of the standby motor group 16 is driven to drive the second drive gear 162 by the backup motor 161 to drive the transmission gear 141 to rotate. Making the second transmission set 14 The power can be continuously transmitted; in addition, in order to smoothly reset the push arm 121, the link piece 122, and the bridge gear 1221 of the first transmission group 12, the elastic body 173 of the elastic return mechanism 17 will generate a returning force upon resetting. In order to ensure that the first transmission group 12 is indeed reset to the initial position, as shown in "Fig. 9".
