    • A coin discrimination apparatus and method is provided. Coins, preferably after cleaning, e.g. using a trommel, are singulated by a coin pickup assembly configured to reduce jamming. A coin rail assists in providing separation between coins as they travel past a sensor. The sensor provides an oscillating electromagnetic field generated on a single sensing core. The oscillating electromagnetic field is composed of one or more frequency components. The electromagnetic field interacts with a coin, and these interactions are monitored and used to classify the coin according to its physical properties. All frequency components of the magnetic field are phase-locked to a common reference frequency. The phase relationships between the various frequencies are fixed, and the interaction of each frequency component with the coin can be accurately determined without the need for complicated electrical filters. In one embodiment, a sensor having a core, preferably ferrite, which is curved, such as in a U-shape or in the shape of a section of a torus, and defining a gap, is provided with a wire winding for excitation and/or detection. The sensor can be used for simultaneously obtaining data relating to two or more parameters of a coin or other object, such as size and conductivity of the object. Two or more frequencies can be used to sense core and/or cladding properties. Objects recognized as acceptable coins, using the sensor data, are diverted by a controllable deflecting door, to tubes for delivery to acceptable coin bins.
    • 提供了一种硬币识别装置和方法。 硬币,优选清洁后,例如。 使用转筛,被配置成减少卡纸的硬币拾取组件分开。 硬币轨道有助于在硬币经过传感器时提供分离。 传感器提供在单个感测芯上产生的振荡电磁场。 振荡电磁场由一个或多个频率分量组成。 电磁场与硬币相互作用,这些相互作用被监测并用于根据其物理特性对硬币进行分类。 磁场的所有频率分量都锁相到公共参考频率。 各种频率之间的相位关系是固定的,并且可以精确地确定每个频率分量与硬币的相互作用,而不需要复杂的电过滤器。 在一个实施例中,具有弯曲的诸如U形或环形截面形状并且限定间隙的铁心的传感器优选为铁氧体,其具有用于激发和/ 或检测。 传感器可以用于同时获得与硬币或其他物体的两个或多个参数相关的数据,例如物体的尺寸和电导率。 可以使用两个或更多个频率来感测芯和/或包层属性。 使用传感器数据识别为可接受的硬币的物体被可控制的偏转门转移到用于传送到可接受的硬币箱的管道上。

    • The present invention relates to a coin counter (1) suitable with different shapes and/or sizes. The counter (1) has a linear array (13) of discrete light sensors (14) extending transversely across a coin travel path (12) having a guide member (15) at one side. The sensors (14) are disposed at different predetermined separations from the guide member (15), and a light source (20) is provided opposite the array (13) so that a coin (10) passing along the coin travel path (12) will interrupt the light (19) path between the light source (20) and one or more of the sensors (14). The array (13) is connected to an electrical circuit means including a processing (P) for receiving output signals from the sensors (14) indicating shading or otherwise thereof by individual coins (10), at short periodic intervals substantially less than the the transit time of an individual coin (10). The processor (P) means is formed and arranged for comparing a coin (10) profile reading defined by a sequence of such signals relating to the passage of a single coin (10) with a plurality of coin profile readings corresponding to the different coins (10) and held in a memory means (M) connected to the processor (P) thereby to identify said coin (10), and then incrementing a register (R) holding the total number of coins (10) having of the same type as that coin (10). The processor (P) further has output means for providing at least one of the total number of each of the different coin types in the mixture, and the total values of each of the different coins corresponding to the total numbers multiplied by the respective values of said coins.
    • 本发明涉及适合于不同形状和/或尺寸的硬币计数器(1)。 计数器(1)具有横向穿过硬币行进路径(12)的离散的光传感器(14)的线性阵列(13),硬币行进路径(12)在一侧具有引导构件(15)。 所述传感器(14)以与所述引导构件(15)不同的预定间隔设置,并且在所述阵列(13)的对面设置光源(20),使得沿着所述硬币行进路径(12)通过的硬币(10) 将中断光源(20)和一个或多个传感器(14)之间的光(19)路径。 阵列(13)连接到电路装置,该电路装置包括用于接收来自传感器(14)的输出信号的处理(P),所述传感器指示各个硬币(10)的阴影或其它方式,其短周期间隔基本上小于所述传输 个人硬币的时间(10)。 处理器(P)装置被形成和布置成用于将由与单个硬币(10)的通过相关的这种信号的序列定义的硬币(10)轮廓读数与对应于不同硬币的多个硬币简档读数进行比较 10)并且保持在连接到处理器(P)的存储装置(M)中,从而识别所述硬币(10),然后增加保存具有相同类型的硬币总数(10)的寄存器(R) 那枚硬币(10)。 处理器(P)还具有用于提供混合物中的每种不同硬币类型的总数中的至少一个的输出装置,并且对应于总数乘以相应值的总数的每个不同硬币的总值 说硬币。
