A multifunctional screening and bead removal motor device

Abstract

This invention proposes a multifunctional bead-removing and sorting motor device, including a mounting base and a bead hopper. The bead hopper is fixedly connected to the top of the mounting base, and a pressure plate is fixedly connected to the inner side of the bead hopper. A bead-clamping toothed disc is movably connected to the surface of the mounting base, and a side plate is fixedly connected to the edge of the bottom surface of the mounting base. A motor mounting plate is fixedly connected to the bottom surface of the mounting base, and a precision motor is fixedly connected to the bottom of the motor mounting plate. The advantages of this invention are: oversized beads remain in the bead hopper; the mounting base is partially hollowed out, and this hollowed-out area corresponds to the sorting position of the bead-clamping toothed disc, allowing smaller beads to fall directly and be collected in the machine, thus achieving the sorting of unqualified beads. This device not only realizes the bead-removing function but also has the function of sorting beads, separating larger and smaller beads, avoiding the sorting and recycling of unqualified beads in game equipment.

Description

Technical Field

[0001] This utility model relates to the field of bead ejection motor technology for game machines, and in particular to a multifunctional bead ejection motor device. Background Technology

[0002] In the gaming equipment industry, especially in coin-operated games, amusement devices (such as slot machines and fishing games), or children's playgrounds, the use of standardized beads (usually spherical) as game tokens or operating mediums is a common practice. These devices typically include the core function of bead dispensing (bead return). In daily operation and maintenance, ensuring that the size of the circulating beads conforms to the standard is crucial. Beads with surface stains or impurities will be larger, potentially causing machine jamming. Worn or broken beads will be smaller, posing a risk of accidental swallowing (in children's equipment) or potential use for illegal operations (such as cheating with small beads in some amusement devices). Furthermore, beads collected in bulk must undergo strict size screening before being reintroduced into the cycle.

[0003] However, the existing technologies for implementing these functions have significant limitations and shortcomings:

[0004] Traditional solutions typically require separate equipment or modules to perform bead sorting (removing oversized or undersized beads) and precise dispensing (bead removal). The sorting process may rely on a vibrating screen or manual selection, while bead removal uses a dedicated bead-removing motor in conjunction with a track or ejector mechanism. Physically integrating these two functional modules increases the complexity and size of the overall equipment structure, raises costs, and is difficult to accommodate within the limited space inside a multi-functional game machine cabinet. Therefore, a multi-functional bead-removing motor device is proposed, capable of both bead removal and sorting. Utility Model Content

[0005] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0006] Therefore, one objective of this utility model is to propose a multifunctional screening and bead-removing motor device to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0007] To achieve the above objectives, one embodiment of the present invention provides a multifunctional screening and bead-removing motor device, including a mounting base and a bead hopper, wherein the top of the mounting base is fixedly connected to the bead hopper, and a pressure plate is fixedly connected to the inner side of the bead hopper;

[0008] The surface of the mounting base is movably connected to a ball bearing, and a side plate is fixedly connected to the edge of the bottom surface of the mounting base;

[0009] A motor mounting plate is fixedly connected to the bottom surface of the mounting base, and a precision motor is fixedly connected to the bottom of the motor mounting plate.

[0010] The output end of the precision motor is connected to a ball bearing disk via several gear transmissions.

[0011] The bottom of the mounting base is fixedly connected to a rail, the outer end of the rail is inclined downwards, and the side plate has a rail outlet;

[0012] The mounting base has an opening that connects to the top of the track. A counting bracket is fixedly connected to the bottom of the mounting base, and a counting sensor is fixedly connected to the bottom of the counting bracket. The detection end of the counting sensor faces the top of the track.

[0013] Preferably, in any of the above embodiments, the mounting base and the bead hopper are connected by screws, and the bead-holding disc is located between the pressure plate and the mounting base.

[0014] Using the above technical solution: This equipment is specifically designed for removing and sifting beads in game equipment.

[0015] In this equipment, the bead hopper temporarily stores the beads. When beads need to be ejected, the precision motor starts. The precision motor and the counting sensor on the counting bracket are connected to the same main control board. When the counting sensor counts a certain number of beads for output, the precision motor stops working. During bead ejection, the precision motor drives the bead-holding toothed disc to rotate. The depth of the tooth grooves on the bead-holding disc is slightly smaller than the radius of the bead to prevent multiple beads from getting stuck in the same groove at the same time. As the bead-holding disc rotates, the grooves "capture" the beads one by one and bring them into the transmission channel. Beads that are not the correct size, i.e., larger beads, will remain in the bead hopper. The mounting base has a partial cutout, which corresponds to the screening position of the bead-holding toothed disc. Smaller beads will fall directly and be collected in the machine, thus achieving the screening of unqualified beads. Beads that are of the correct size are brought to a higher position by the bead-holding toothed disc, corresponding to the opening of the mounting base. The beads enter the track through this opening and slide down the track naturally for output, thus achieving bead ejection. The counting sensor uses the infrared counting principle to count each bead that falls onto the track.

[0016] In this device, as the bead-catching disc rotates, the grooves "capture" the beads one by one and bring them into the conveying channel. Oversized beads remain in the bead hopper, where the mounting base has a partially open section corresponding to the screening position of the bead-catching disc. Smaller beads fall directly out and are collected in the machine, thus screening out defective beads. This device not only performs the bead ejection function but also filters beads, separating larger and smaller ones, avoiding the need for sorting and recycling of oversized beads in gaming equipment.

[0017] Preferably, in any of the above embodiments, the ball bearing disc has several screening positions, where the mounting base is hollowed out.

[0018] The above technical solution comprises the following components: a mounting base serves as the equipment base, with a bead hopper (used for temporarily storing beads to be processed) fixedly connected to its top by screws. A pressure plate is fixedly installed inside the bead hopper, forming a limiting channel between the pressure plate and the mounting base.

[0019] The mounting base surface is movably connected to a rotatable ball-holding disc via bearings. The edge of the ball-holding disc is machined with equidistant grooves (i.e., screening positions), and the groove depth is designed to be slightly less than the radius of a standard ball (ensuring that only a single ball can be inserted). The mounting base is partially hollowed out at the corresponding groove positions.

[0020] The mounting base has a side plate riveted to its bottom edge, which defines the working area boundary and has a track outlet. A precision motor is fixed to the bottom via screws on a motor mounting plate. The output of the precision motor is driven by a gear set for speed reduction and torque amplification, then connected to a ball bearing gear.

[0021] The bottom of the mounting base is welded with a stainless steel track. The inner diameter of the track is designed to allow only a single ball to pass through, and its outer end extends downwards at an angle to the side plate outlet. The top opening of the track is directly opposite the ball retraction opening on the mounting base.

[0022] The counting bracket is fixed below the mounting base and located on the outer side of the top of the track, with a counting sensor (infrared through-beam type) installed at its bottom. The detection end of the counting sensor is precisely aligned with the lower edge of the top opening of the track to monitor the bead falling signal in real time.

[0023] Preferably, in any of the above solutions, the mounting base is riveted to the side plate, and the precision motor is connected to the motor mounting plate by screws.

[0024] Preferably, of any of the above solutions, the track is made of stainless steel and the track allows only a single bead to be output.

[0025] Preferably, in any of the above embodiments, the counting bracket is located outside the top of the track.

[0026] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0027] This multi-functional bead-removing and sorting motor device uses a rotating bead-catching disc to individually "capture" beads and guide them into the transport channel. Oversized beads remain in the bead hopper, where a partially perforated mounting base corresponds to the sorting position on the bead-catching disc. Smaller beads fall directly into the machine and are collected, thus separating defective beads. This device not only removes beads but also sorts them, preventing the disposal of oversized beads in gaming equipment.

[0028] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0036] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0037] like Figure 1-4 As shown, this multi-functional screening and bead removal motor device includes a mounting base 1 and a bead hopper 2. The top of the mounting base 1 is fixedly connected to the bead hopper 2, and the inner side of the bead hopper 2 is fixedly connected to the pressure plate 3.

[0038] A ball bearing 4 is movably connected to the surface of the mounting base 1, and a side plate 5 is fixedly connected to the edge of the bottom surface of the mounting base 1.

[0039] A motor mounting plate 6 is fixedly connected to the bottom surface of the mounting base 1, and a precision motor 7 is fixedly connected to the bottom of the motor mounting plate 6.

[0040] The output end of the precision motor 7 is connected to the ball bearing disk 4 via several gear transmissions;

[0041] The bottom of the mounting base 1 is fixedly connected to a rail 9, the outer end of the rail 9 is inclined downward, and the side plate 5 has an outlet of the rail 9;

[0042] Mounting base 1 has an opening that connects to the top of track 9. A counting bracket 10 is fixedly connected to the bottom of mounting base 1. A counting sensor 11 is fixedly connected to the bottom of counting bracket 10. The detection end of counting sensor 11 faces the top of track 9.

[0043] Example 1: The mounting base 1 and the bead hopper 2 are connected by screws. The bead-holding disc 4 is located between the pressure plate 3 and the mounting base 1. The bead-holding disc 4 has several screening positions, where the mounting base 1 is hollowed out. The mounting base 1 is riveted to the side plate 5, and the precision motor 7 is connected to the motor mounting plate 6 by screws. The track 9 is made of stainless steel and only allows a single bead to be output. The counting bracket 10 is located on the outer top of the track 9.

[0044] Example 2: This device is specifically designed for removing and sifting beads in gaming equipment.

[0045] In this device, the bead hopper 2 temporarily stores the beads. When beads need to be ejected, the precision motor 7 starts. The precision motor 7 and the counting sensor 11 on the counting bracket 10 are connected to the same main control board. When the counting sensor 11 counts a certain number of beads, the precision motor 7 stops working. During bead ejection, the precision motor 7 drives the bead-holding toothed disc 4 to rotate. The tooth groove depth of the bead-holding toothed disc 4 is slightly smaller than the radius of the bead to prevent multiple beads from being stuck in the same tooth groove at the same time. As the bead-holding toothed disc 4 rotates, the tooth grooves "capture" the beads one by one and bring them into the transmission channel. Beads that are not the correct size, i.e., larger beads, will remain in the bead hopper 2. The mounting base 1 is partially hollowed out, and this hollowed-out area corresponds to the screening position of the bead-holding toothed disc 4. Smaller beads will fall directly and be recycled in the machine, thus achieving the screening of unqualified beads. A bead of the correct size is carried to a high position by the bead-holding disc 4, corresponding to the opening of the mounting base 1. The bead enters the track 9 through this opening and slides down naturally along the track 9 to be output, thus realizing the bead ejection. The counting sensor 11 uses the infrared counting principle to count each bead that falls to the track 9.

[0046] Device Composition: Mounting base 1 serves as the equipment base, with a bead hopper 2 (used for temporarily storing beads to be processed) fixedly connected to its top by screws. A pressure plate 3 is fixedly installed inside the bead hopper 2, forming a limiting channel between the pressure plate 3 and the mounting base 1.

[0047] The mounting base 1 is movably connected to a rotatable ball-holding disc 4 via bearings. The edge of the ball-holding disc 4 is machined with equally spaced grooves (i.e., screening positions), and the groove depth is designed to be slightly smaller than the radius of a standard bead (to ensure that only a single bead can be inserted). The mounting base 1 is partially hollowed out at the corresponding groove positions.

[0048] The mounting base 1 has a side plate 5 riveted to its bottom edge, which defines the working area boundary and has a track outlet. A precision motor 7 is fixed to the bottom via screws on a motor mounting plate 6. The output of the precision motor 7 is driven by a gear set for speed reduction and torque amplification, then connected to a ball bearing 4.

[0049] The bottom of the mounting base 1 is welded with a stainless steel track 9. The inner diameter of the track 9 is designed to allow only a single ball to pass through, and its outer end extends downwards at an angle to the outlet of the side plate 5. The top opening of the track 9 is directly opposite the ball retraction opening on the mounting base 1.

[0050] The counting bracket 10 is fixed below the mounting base 1 and located on the outer side of the top of the track 9, with a counting sensor 11 (infrared through-beam type) installed at its bottom. The detection end of the counting sensor 11 is precisely aligned with the lower edge of the top opening of the track 9 to monitor the bead falling signal in real time.

[0051] The working principle of this utility model is as follows:

[0052] Initialization and feeding: Beads to be processed are stored in bead hopper 2. Pressure plate 3 limits the bead stacking height, ensuring that the beads contact the tooth surface of the bead-holding disc 4 in a single layer.

[0053] The ball retraction and triple screening mechanism, after starting the precision motor 7, drives the ball-holding disk 4 to rotate in a specific direction through the gear set, performing the following key operations:

[0054] In the first stage of screening (large bead blocking), the beads are embedded into the grooves of the bead-holding disc 4 under the influence of gravity. Because the groove depth is less than the radius of a standard bead, extra-large diameter beads cannot be fully embedded in the groove and are blocked by the tooth surface of the disc and remain in the bead hopper 2.

[0055] Secondary screening (small bead recycling): When the slotted beads rotate with the toothed disc 4 to the hollow screening position, beads with a diameter smaller than the standard fall directly from the hollow due to gravity and are recycled to the waste bin (or returned to the feed hopper) through the internal channel of the equipment.

[0056] Qualified beads are conveyed, and beads of the correct size continue to rotate under the drive of the tooth groove. When they reach the bead unloading opening of the mounting seat 1, they are released from the tooth groove due to gravity and fall precisely into the top opening of the track 9.

[0057] The track conveying and counting control system ensures that qualified beads enter the inclined track 9 and naturally accelerate towards the exit. The counting sensor 11 (infrared type) detects in real time at the top of track 9: each bead blocking the infrared beam as it falls triggers a counting pulse.

[0058] The control system (main control board) accumulates the number of counted pulses.

[0059] When the count reaches the preset amount of beads to be ejected, the main control board immediately controls the precision motor 7 to stop rotating, thus achieving precise quantitative bead ejection.

[0060] Compared with the prior art, the present invention has the following advantages:

[0061] This multi-functional bead-removing and sorting motor device uses a rotating bead-catching disc 4. The teeth individually "capture" the beads and guide them into the transport channel. Larger beads remain in the bead hopper 2. The partially open mounting base 1 corresponds to the sorting position on the bead-catching disc 4, allowing smaller beads to fall directly and be collected in the machine, thus achieving the sorting of defective beads. This device not only removes beads but also sorts them, separating larger and smaller beads and avoiding the need for sorting and recycling of unqualified beads in gaming equipment.
