A coin channel selection structure

Abstract

A coin channel selection structure for reversing the direction of rolling coins includes a drive unit, a timing belt, a slider, multiple reversing blocks, and a support plate. The reversing blocks are rotatably mounted on the support plate. Each reversing block includes a U-shaped groove. Multiple reversing blocks are arranged horizontally so that the multiple U-shaped grooves are joined to form a continuous coin rolling channel. The slider is mounted on the timing belt. When the drive unit drives the timing belt to move, the slider moves synchronously and squeezes one of the reversing blocks. After being squeezed, the reversing block rotates relative to the support plate, causing a gap to form in the local coin rolling channel corresponding to the U-shaped groove of the reversing block. The coin falls through the gap, completing the reversal. This coin channel selection structure is characterized by low cost and a simple structure.

Description

Technical Field

[0001] This utility model relates to the technical field of coin handling devices, specifically to a coin channel selection structure. Background Technology

[0002] In existing coin reversal processes, coins mostly roll from high to low. Traditional coin channel selection structures often use a combination of solenoid valves and mechanical levers to control the coin's reversal during the rolling process. The solenoid valves require additional circuit control, resulting in a complex structure, while the lever mechanism requires multi-stage transmission and precise calibration, leading to high maintenance costs. Therefore, there is an urgent need for a coin channel selection structure to solve the above problems. Utility Model Content

[0003] In view of this, a low-cost and simple coin channel selection structure is provided.

[0004] A coin channel selection structure for reversing the direction of rolling coins includes a drive unit, a timing belt, a slider, multiple reversing blocks, and a support plate. The reversing blocks are rotatably mounted on the support plate. Each reversing block includes a U-shaped groove. Multiple reversing blocks are arranged horizontally so that the multiple U-shaped grooves are spliced ​​together to form a continuous coin rolling channel. The slider is mounted on the timing belt. When the drive unit drives the timing belt to move, the slider moves synchronously and squeezes one of the reversing blocks. After being squeezed, the reversing block rotates relative to the support plate, causing a gap to be formed in the local coin rolling channel corresponding to the U-shaped groove of the reversing block. The coin falls from the gap, completing the reversal.

[0005] Furthermore, the reversing block has rotating shaft protrusions on both sides, and the support plate has a first receiving groove corresponding to the rotating shaft protrusions, with the rotating shaft protrusions installed in the first receiving grooves.

[0006] Furthermore, the reversing block also includes a push head facing the synchronous belt, and the U-shaped groove and the push head are located on both sides of the axial direction of the rotating shaft protrusion. The reversing block uses the rotating shaft protrusion as the pivot point.

[0007] Furthermore, the coin channel selection structure also includes a first baffle, the support plate is provided with a limiting post, the limiting post is used to position the first baffle, the support plate is detachably connected to the first baffle by fasteners, and the first baffle is used to cover the first receiving groove to prevent the rotating shaft protrusion from coming out.

[0008] Furthermore, the coin channel selection structure also includes a reset elastic element, and the reversing block also includes a connecting part. One end of the reset elastic element acts on the connecting part, and the other end is fixed. When the slider squeezes the reversing block, the reset elastic element is stretched to produce elastic deformation. After the slider leaves, the reversing block is reset by elastic force so that the U-shaped groove is reassembled to form a complete coin rolling channel.

[0009] Furthermore, the slider has a second receiving groove in the middle, the timing belt passes through the second receiving groove, and the coin channel selection structure also includes a second baffle, which is detachably connected to the slider. The second baffle is used to block the second receiving groove to prevent the timing belt from coming out.

[0010] Furthermore, the inner side of the synchronous belt has a toothed structure, and the groove wall of the second receiving groove is provided with teeth, which engage with the toothed structure to engage and fix the slider with the synchronous belt.

[0011] Furthermore, the reversing block also includes a baffle, which is an arc extending from the reversing block. The arc is configured such that when the reversing block is compressed and rotates relative to the support plate, the baffle can rotate to be opposite the coin rolling channel to prevent the coin from jumping over the gap.

[0012] Furthermore, the driving component includes a motor and a driving wheel, the driving wheel is mounted on the output end of the motor, the inner side of the synchronous belt has a toothed structure, and the driving wheel is meshed with the synchronous belt.

[0013] Furthermore, the coin channel selection structure also includes a transmission bracket and a synchronous wheel. The transmission bracket is fixed to the support plate, and the synchronous wheel and the motor are both mounted on the transmission bracket. The synchronous wheel and the drive wheel are connected by a synchronous belt.

[0014] Compared with the prior art, the present invention has at least the following beneficial effects: This coin selection structure uses a synchronous belt to drive a slider that directly presses against the reversing block, eliminating the need for multi-stage transmission mechanisms and additional circuitry such as solenoid valves. After the reversing block rotates under pressure, a gap appears in the coin rolling channel. The coin rolls to the gap and falls through, completing the reversal. It is low-cost and has a simplified structure. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1 to 9This illustration shows a coin channel selection structure provided by an embodiment of the present invention, used to change the direction of rolling coins. It includes a drive unit, a timing belt 1, a slider 2, multiple reversing blocks 3, and a support plate 4. Each reversing block 3 is rotatably mounted on the support plate 4. Each reversing block 3 includes a U-shaped groove 5. Multiple reversing blocks 3 are arranged horizontally so that the multiple U-shaped grooves 5 are joined to form a continuous coin rolling channel. The slider 2 is mounted on the timing belt 1. When the drive unit drives the timing belt 1 to move, the slider 2 moves synchronously and squeezes one of the reversing blocks 3. After being squeezed, the reversing block 3 rotates relative to the support plate 4, causing a gap 6 to be formed in the local coin rolling channel corresponding to the U-shaped groove 5 of the reversing block 3. The coin falls from the gap 6, completing the reversal.

[0027] In some specific embodiments, the reversing block 3 is mounted on the support plate 4 and the push head 9 can rotate around the rotating shaft protrusion 7. At the same time, the U-shaped grooves 5 of a row of multiple reversing blocks 3 are connected end to end to form a coin rolling channel. When the coin channel selection structure is in the initial state, the coin rolling channel is a complete channel. When a coin falls onto the channel, it can roll along the channel. When a reversal is required, the motor 17 drives the synchronous belt 1 and the slider 2 to move. When the slider 2 moves to the last reversing block 3 and stops there, the slider 2 squeezes the push head 9 of the reversing block 3, causing the reversing block 3 to rotate around the support plate 4. After rotation, the section of the coin rolling channel corresponding to this reversing block 3 is missing. At this time, the rolling coin enters the rolling channel and falls from the gap 6. Since the gap 6 opens the reversing channel, the rolling coins will all fall from the reversing channel connected to this gap 6, thus realizing the reversal selection. If it is necessary to switch to another reversing channel, the motor 17 continues to drive the synchronous belt 1 and the slider 2 to move. After the slider 2 leaves the last reversing block 3, the last reversing block 3 is reset by the pulling force of the reset elastic element 12. When the slider 2 moves to the reversing block 3 corresponding to the predetermined reversing channel, it can stop and achieve reversing selection as described above.

[0028] In some specific embodiments, slider 2 needs to move to the reversing block 3 corresponding to the predetermined reversing channel and stay there. After the predetermined reversing channel is opened, the coin is dispensed into the rolling channel and will fall from the gap 6 corresponding to the predetermined reversing channel. When the reversing channel needs to be changed, the coin dispensing is paused first, slider 2 moves to the reversing block 3 corresponding to the new reversing channel and stays there. After the new reversing channel is opened, the coin is dispensed again and will fall from the gap 6 corresponding to the new reversing channel, thereby realizing the ability to switch multiple reversing channels.

[0029] like Figure 7 and Figure 8 As shown, specifically, the two sides of the reversing block 3 are provided with pivot protrusions 7, and the support plate 4 is provided with a first receiving groove 8 corresponding to the pivot protrusions 7, and the pivot protrusions 7 are installed in the first receiving groove 8.

[0030] More specifically, the reversing block 3 also includes a push head 9, which faces the synchronous belt 1. The U-shaped groove 5 and the push head 9 are respectively disposed on the axial sides of the rotating shaft protrusion 7, and the reversing block 3 uses the rotating shaft protrusion 7 as the fulcrum for rotation.

[0031] More specifically, the coin channel selection structure further includes a first baffle, the support plate 4 is provided with a limiting post 11, the limiting post 11 is used to position the first baffle, the support plate 4 is detachably connected to the first baffle by fasteners, and the first baffle is used to cover the first receiving groove 8 to prevent the rotating shaft protrusion 7 from coming out.

[0032] Specifically, the coin channel selection structure further includes a reset elastic element 12, and the reversing block 3 further includes a connecting part 13. One end of the reset elastic element 12 acts on the connecting part 13, and the other end is fixed. When the slider 2 squeezes the reversing block 3, the reset elastic element 12 is stretched and generates elastic deformation. After the slider 2 leaves, the reversing block 3 is reset by the elastic force so that the U-shaped groove 5 is reassembled to form a complete coin rolling channel. In some specific embodiments, the reset elastic element 12 is preferably a spring. One end of the spring is hooked to the connecting part 13, and the other end is hooked to the support plate 4. When the slider 2 presses the push head 9 of the reversing block 3 and causes the push head 9 to rotate around the rotating shaft protrusion 7, the connecting part 13 of the reversing block 3 rotates towards the transmission bracket 19, and the spring is stretched. When the slider 2 leaves the reversing block 3 and the pressing force is eliminated, the connecting part 13 of the reversing block 3 is pulled back to its original position under the elastic force of the spring. The U-shaped groove 5 of the reversing block 3 is also reset and rotated back to its initial position, connecting with the U-shaped groove 5 of the adjacent reversing block 3. More specifically, the groove length direction of the U-shaped groove 5 is consistent with the arrangement direction of the reversing blocks 3. Therefore, after the U-shaped groove 5 of the reversing block 3 is reset synchronously, the U-shaped grooves 5 of each reversing block 3 are spliced ​​together to form a continuous coin rolling channel.

[0033] Specifically, the slider 2 has a second receiving groove 14 in the middle, the timing belt 1 passes through the second receiving groove 14, and the coin channel selection structure also includes a second baffle. The second baffle is detachably connected to the slider 2 and is used to block the second receiving groove 14 to prevent the timing belt 1 from coming off.

[0034] More specifically, the inner side of the synchronous belt 1 is a toothed structure 10, and the groove wall of the second receiving groove 14 is provided with teeth 15. The teeth 15 engage with the toothed structure 10 to engage and fix the slider 2 with the synchronous belt 1. The engaging structure is the preferred embodiment, but a snap-fit ​​structure, magnetic structure, etc. can also be used to fix the slider 2 with the synchronous belt 1.

[0035] Specifically, the reversing block 3 further includes a baffle 16, which is an arc shape extending from the reversing block 3. The arc shape is designed so that when the reversing block 3 is squeezed and rotates relative to the support plate 4, the baffle 16 can rotate to be opposite to the coin rolling channel to prevent the coin from jumping over the gap 6.

[0036] Specifically, the driving component includes a motor 17 and a drive wheel 18. The drive wheel 18 is mounted on the output end of the motor 17. The inner side of the synchronous belt 1 has a toothed structure 10. The drive wheel 18 is meshed with the synchronous belt 1.

[0037] More specifically, the coin channel selection structure also includes a transmission bracket 19 and a synchronous wheel 20. The transmission bracket 19 is fixed to the support plate 4. The synchronous wheel 20 and the motor 17 are both mounted on the transmission bracket 19. The synchronous wheel 20 is connected to the drive wheel 18 via a synchronous belt 1.

[0038] In summary, this coin channel selection structure uses a synchronous belt 1 to drive the slider 2 to directly press the reversing block 3, eliminating the need for multi-stage transmission mechanisms and additional circuit control such as solenoid valves. After the reversing block 3 is pressed and rotated, a gap 6 appears in the coin rolling channel. The coin rolls to the gap 6 and falls from the gap 6, thus completing the reversal. It is low-cost, has a simple structure, and can select multiple reversing channels separately. The purpose of coin selection is achieved by switching the reversing channels, making it highly practical.

[0039] It should be noted that this utility model is not limited to the above-described embodiments. Based on the inventive spirit of this utility model, those skilled in the art can make other changes, and these changes made based on the inventive spirit of this utility model should be included within the scope of protection claimed by this utility model.
