Definitions

  • the invention relates to a product storage device for retailing, in particular to an intelligent shelf.
  • weight sensors are generally installed under the stalls, and the types and quantities of the sold goods are judged by real-time monitoring of the weight changes of the goods on different stalls.
  • the two adjacent columns and the goods on the two columns cannot have any form of contact, otherwise the data accuracy of the weight sensor will be affected.
  • the column size of the shelf is usually not adjustable, and the width and spacing of the column cannot be adjusted by itself.
  • the width of each column of this type of shelf is limited, and it cannot adapt to goods of different sizes.
  • the widths of different types of goods in convenience stores are often different. If the width of each column is constant, there will be very few types of goods that can be placed on each shelf. For goods with different widths, it is necessary to prepare a large number of pallets of different widths. Each pallet is used to place goods of appropriate size, and storage costs, management costs, and operating costs are high.
  • Chinese patent CN108703590A discloses a shelf, which adopts the design of the pallet as a splicable and combinable structure, the weight sensor is detachably mounted on the shelf substrate through the clamp, and the pallet is detachably mounted on the weight sensor through the clamp.
  • each pallet is a column, and a weight sensor is arranged in the middle below each pallet. The operator can remove the tray and the weight sensor from the shelf substrate, and splice multiple trays into one tray, so that the tray can place goods of different widths and reduce the management cost of the operator.
  • this solution removes, moves and installs the weight sensor, so that there is only one weight sensor in the middle of the lower part of the combined tray, so that the middle part of the width-adjusted tray is directly above the weight sensor to ensure that the sensor collects the weight value. accuracy.
  • the operation process for the operator to adjust the width of the pallet is too cumbersome and cannot be adjusted directly on the shelf. For example, if the operator wants to adjust the width of the pallet to be larger, he needs to remove multiple pallets from the shelf, remove the side panels on the left and right sides of the pallet, connect multiple pallet components together, and also need to install the weight sensor Remove a few, adjust the positions of the remaining weight sensors, and then install the assembled pallet on the shelf so that each sensor is located in the middle of a pallet. If the number and position of the weight sensors are not adjusted, the center of gravity of the pallet will be inconsistent with the sensors, which will affect the accuracy of the sensors.
  • the weight data collected by the weight sensor in real time includes the weight of the pallet, fixture, and goods on the pallet. Since the range of each sensor is limited, the weight of the combined pallet itself is relatively large, and the weight of the fixture is also large, which will occupy the sensor. A larger part of the range forces the operator to choose a weight sensor with a larger range and higher cost, thereby increasing the cost of the shelf. For example, in the scheme of the aforementioned reference document, if only a weight sensor with a measuring range upper limit of 3 kg is selected, but the total weight of the combined pallet and fixture reaches 1 kg, then only lighter goods can be placed on the pallet. However, generally wide items are likely to be heavy as well, so convenience store operators are forced to use weight sensors with a measuring range of up to 10 kg.
  • each shelf needs to install a large number of fixtures (one weight sensor needs to install two fixtures), which inevitably increases the hardware cost of the shelf.

Abstract

一种货架，包括安装支架及货架板（100），货架板（100）包括基板（10）、两个以上支架（20）、两个以上重量传感器（30）以及两个以上托盘（40）；相邻的两个以上托盘（40）组成一个栏位（110），每一栏位（110）用以摆放同一种类的至少一货品。

Description

一种货架 技术领域
本发明涉及一种用于零售业的货品存放装置，具体地说，涉及一种智能货架。
背景技术
在无人超市或无人便利店技术中，需要解决顾客选购货品的判断和记录问题，具体地说，需要用计算机系统准确判定顾客从货架上取走货品的种类、取走货品的数量及单价等，以便为顾客结算。
现有技术中，一般是在栏位下方安装重量传感器，通过实时监控不同栏位上货品的重量变化的方式来判断售出货品的种类和数量。在这类方案中，相邻的两个栏位及两个栏位上的货品不能有任何形式的接触，否则会影响重量传感器的数据准确性。
现有技术中，货架的栏位尺寸通常是不可调节的，栏位的宽度、间距也不能自行调整，这类货架每一栏位的宽度有限，不能适应不同尺寸的货品。
然而，便利店中不同种类货品的宽度往往是不同的，如果每一栏位的宽度是恒定不变的，每一货架能摆放的货品种类就会很少，便利店经营者为了摆放不同宽度的货品，需要准备大量不同宽度的托盘，每一托盘用于摆放尺寸合适的货品，仓储成本、管理成本、运营成本都很高。
在无人便利店领域，需要有一种栏位间距可调整的货架，从而可以用于摆放不同宽度、不同种类的货品，从而降低便利店的仓储成本和管理成本。
中国专利CN108703590A中公开了一种货架，其采用将托盘设计为可拼接可组合的结构，将重量传感器通过夹具可拆卸式安装在货架基板上，将托盘通过夹具可拆卸式安装在重量传感器上。在这一方案中，每一托盘就是一个栏位，每个托盘下方的中部设置一个重量传感器。经营者可以将托盘、重量传感器从货架基板上取下，将多个托盘拼接成一个托盘，从而使得托盘可以摆放不同宽度的货品，减少经营者管理成本。同时，这一方案通过拆除、移动和安装重量传感器，使得组合后托盘下方的中部有且仅有一个重量传感器，让宽度调整后的托盘的中部在重量传感器正上方，以保证传感器采集重量数值的准确性。
这一方案的不足之处在于：
第一，当多个托盘组件彼此连接组合成一个大托盘时，托盘与重量传感器之间仅有一个夹具，重量传感器与底板之间仅有一个夹具，托盘四角处容易发生晃动，稳定性较差，会影响重量传感器的数据精度。重量传感器在安装时，如果不是设置在大托盘中部的下方，托盘及商品的重心不在传感器的正上方，也会影响传感器的数据精度。
第二，经营者调整托盘宽度的操作过程太过繁琐，不能直接在货架上调整。例如，经营者若想要将托盘宽度调整更大，需要将多个托盘从货架上取下，将托盘左右两侧的侧板拆除，将多个托盘组件拼合连接为一体，还需要将重量传感器取下几个，再调整剩下几个重量传感器的位置，再将拼装好的托盘安装在货架上，使得每一个传感器位于一个托盘下方中部。如果不调整重量传感器的数量和位置，就会导致托盘重心与传感器不一致，从而影响传感器的精度。
第三，重量传感器实时采集的重量数据包括托盘、夹具以及托盘上货品的重量，由于每个传感器的量程是有限的，组合后的托盘自身重量较大、夹具的重量也较大，会占据传感器量程中较大的一部分，迫使经营者选择更大量程、成本更高的重量传感器，从而提升货架成本。例如，在前述对比文件的方案中，若仅选择量程上限为3公斤的重量传感器，但组合后的托盘和夹具的总重量就达到了1公斤，那么托盘上只能摆放较轻的货品。然而，一般宽度较大的货品很可能重量也很大，因此，便利店经营者被迫要使用量程上限为10公斤的重量传感器。
第四，每一货架都需要安装大量夹具(一个重量传感器要安装两个夹具)，不可避免地提升了货架的硬件成本，虽然可以在一定程度上减少托盘的采购和管理成本，但是降本效果较差，不能满足便利店经营者的需求。

较佳实施方式(实施例1)
以下参考说明书附图介绍本发明的优选实施方式，用以举例证明本发明可以实施，这些实施例可以向本领域中的技术人员完整介绍本发明的技术内容，使得本发明的技术内容更加清楚和便于理解。然而本发明可以通过许多不同形式的实施例来得以体现，本发明的保护范围并非仅限于文中提到的实施例。
在附图中，结构相同的部件以相同数字标号表示，各处结构或功能相似的组件以相似数字标号表示。当一个组件被描述为“连接至”另一组件时，二者可以理解为直接“连接”，或者一个组件通过一中间组件“连接至”另一个组件。
本发明实施例1中提供一种货架，包括落地式安装支架和货架板，货架板的两端可拆卸式安装至所述安装支架，每一货架板水平设置，用于摆放货品。按照零售业的行业习惯，货架板及托盘朝向顾客、靠近顾客的一端被称为前端，远离顾客的一端被称为后端。
如图1-图3所示，货架板100包括基板10、两个以上支架20、两个以上重量传感器30以及两个以上托盘40；具体地，所述两个以上支架20并列设置于基板10上方；每一重量传感器30一端的底面连接至基板10，其另一端的顶面连接至一支架20的底面；每一托盘40被安装至一支架20顶部；其中，相邻的两个以上托盘40组成一个栏位110，每一栏位110用以摆放同一种类的至少一货品。
如图3-图5所示，每一托盘40通过一水平设置的支架20连接至一重量传感器30。
本实施例中，支架20与重量传感器30之间有且仅有一个连接部；连接部为一垫片21，其底面连接至重量传感器30一端的顶面。这样设置使得重量传 感器30的上端连接支架20，其下端连接至基板10，上下两端分别只有一个支点，且分处于水平设置的重量传感器两端，已获得准确性最好的称重效果。
如图3-图6所示，本实施例中，支架20中部包括两根彼此平行的条形杆22以及垫片21；两根彼此平行的条形杆22与重量传感器30的中心线平行；垫片21连接至两根条形杆22，支架20通过垫片21连接至重量传感器30。
如图4-图6所示，支架20还包括第一安装架23和第二安装架24，两个安装架分别位于基板10前端和后端的上方，分别连接至两根条形杆22的两端。支架20中部的垫片21及两根条形杆22，以及支架20两端的第一安装架23和第二安装架24可以为一体化结构，以便增强支架20的刚性，提升托盘的稳定性。
支架20还包括第一条形槽231以及第一安装孔232，第一条形槽231下凹于第一安装架23顶部；第一安装孔232贯穿于第一条形槽231的底面。支架20还包括第二条形槽241以及第二安装孔242；第二条形槽241设于第二安装架24顶部；第二安装孔242贯穿于第二条形槽241的底面。
其中，第一安装架23、第二安装架24与基板10之间存在间隙，用于放置重量传感器30，确保整个支架20与基板10不会发生直接接触，以保证重量传感器30的精度。其中，两个安装架为弯折后的金属薄片，金属薄片上设有镂空孔，既可以保证支架强度又可以尽可能减轻重量，减少支架重量对传感器的量程占用量，且硬件成本较低。
如图4、图7所示，每一托盘40包括托盘底板41、两个托盘侧板42、托盘前板43和托盘后板44。托盘底板41被安装至一支架20顶部，优选两个托盘侧板42分别安装在托盘底板41的左右两侧，托盘前板43可拆卸式安装至托盘底板41或支架20的前端；托盘后板44可拆卸式安装至支架20的后端，托盘侧板42可拆卸式安装至托盘底板41及托盘后板44的一侧或两侧，从托盘40的后端延伸至其前端。托盘底板41、托盘前板43及托盘后板44均安装至支架20，相当于支架20的延伸，使得托盘40的结构更加稳固。在其他实施例中，托盘也可仅设置一个托盘前板43或一个托盘后板44，托盘其他部分的结构也可以作出适当改进。
本实施例中，每一托盘前板43的底面设有突出的前板卡块431，每一托盘后板44的底面设有突出的后板卡块441，托盘底板41的底部的前、后端分别 设突出的底板卡板411，每一底板卡板411的底面设有突出的底板卡块412。
托盘底板41的底部的前端、后端分别设有突出的底板卡板411，与托盘底板41垂直连接。底板卡板411的底部分别设有突出的底板卡块412，可拆卸式卡合至第一安装孔232、第二安装孔242内。
当一托盘底板41被安装至一支架20时，托盘底板41前端的底板卡板411被插入至该支架20的第一条形槽231内，前端的底板卡块412可拆卸式卡合至第一条形槽231的第一安装孔232内；同时，托盘底板41后端的底板卡板411被插入至该支架20的第二条形槽241内，后端的底板卡块412可拆卸式卡合至第二条形槽241的第二安装孔242内。
当一托盘前板43被安装至一支架20时，托盘前板43的下端被插入至该支架20的第一条形槽231内，前板卡块431可拆卸式卡合至第一条形槽231的第一安装孔232内。
当一托盘后板44被安装至一支架20时，托盘后板44的下端被插入至该支架20的第二条形槽241内，后板卡块441可拆卸式卡合至第二条形槽241的第二安装孔242内。
本实施例中，两个前板卡块431的底部的侧壁设有突出的钩板，分别可以卡合至第一安装孔232两侧的内侧壁。由于前板卡块431设有钩板，两个前板卡块431整体结构会比第一安装孔232略宽。托盘前板43的中部或下部设有一第一开口432，延伸至托盘前板43底部，两个前板卡块431分别位于第一开口432两侧。当两个前板卡块431插入第一安装孔232时，托盘前板43可以产生微小形变，使得两个前板卡块431可以插入第一安装孔232，插入过程完成后，托盘前板43恢复原状，两个前板卡块431可以更好地与第一安装孔232实现卡合连接。当托盘前板43需要从支架20拆除时，用力挤压托盘前板43两侧，第一开口432可以使托盘前板43产生微小形变，以便于将前板卡块431拔出。
类似地，两个后板卡块441的底部的侧壁设有突出的钩板，分别可以卡合至第二安装孔242两侧的内侧壁。托盘后板44的中部或下部设有一第二开口442，延伸至托盘后板44底部；两个后板卡块441分别位于第二开口442两侧。当两个后板卡块441插入第二安装孔242时，托盘后板44可以产生微小形变，使得两个后板卡块441可以插入第二安装孔242，插入过程完成后，托盘后板44 恢复原状，两个后板卡块441可以更好地与第二安装孔242实现卡合。同理，当托盘后板44需要从支架20拆除时，用力挤压托盘后板44两侧，第二开口442可以使托盘后板44产生微小形变，以便于将托盘后板44拔出。
如图4-图6所示，本实施例中，每一托盘底板41或支架40左右两侧的边缘处设有第三安装孔413，在每一支架40左右两侧的边缘处设有第四安装孔414，第四安装孔414与第三安装孔413对应设置；每一托盘侧板42的底部设有突出的侧板卡块421，可拆卸式安装至第三安装孔413和/或第四安装孔414内。当一托盘侧板42被安装至一托盘底板41时，托盘侧板42的侧板卡块421插入至第三安装孔413和/或第四安装孔414内。
托盘后板44左右两侧的边缘处设置有竖直式的条形孔443。托盘侧板42的边缘处设置有突出的卡勾422，其向下弯折且延伸；卡勾422与托盘侧板42位于同一平面内，卡勾422可拆卸式卡入至条形孔443内。条形孔443和卡勾422的设置使得托盘侧板42的拆卸更加方便，也使得托盘侧板42在安装后的更加稳定。
在其他实施例中，第三安装孔413和/或第四安装孔414也可以设于每一支架20两侧的边缘处，托盘前板43也可以可拆卸式安装至托盘底板41前端；托盘后板44也可以可拆卸式安装至托盘底板41后端。
本实施例中无需使用夹具，重量传感器30与托盘底板41之间稳固连接，从而使得托盘40不易发生晃动，稳定性较好，使得重量传感器30的实时检测数据的精度更高。本实施例的托盘侧板的拆卸组装简单方便，用户可以直接在货架上直接插拔托盘侧板，简单快捷。
本实施例每个传感器除了承担托盘上的货品重量之外，只需承担一个小支架和一个小托盘的重量，因此只需选用量程较小的重量传感器即可；如果多个小托盘组合成一个栏位，货品的重量会被同一栏位下的多个传感器共同分担，因此可以进一步降低重量传感器的成本。
如图4、图5所示，货架板100还包括加强板101；加强板101固定至基板10的上表面；多个重量传感器30一端的底面连接至同一加强板101。加强板101与基板10之间还可以设置长条形缓冲板103，以实现更好地固定效果，使得整个托盘更加稳定。重量传感器30两端分别设有竖直通孔，在其一端可以用一 螺栓穿过缓冲板103、加强板101，将重量传感器30一端的下表面连接至基板10，在其另一端可以用一螺栓穿过垫片21，将重量传感器30另一端的上表面连接至支架20。
如图4、图5所示，本实施例中，货架板100还包括加强板挡板102；加强板挡板102垂直连接至加强板101的后端，与加强板101制成一体化结构，以进一步提升加强板101的刚性；加强板挡板102与支架20、托盘40之间存在间隙，以免影响重量传感器的测量精度。为了追求货架板的轻量化，货架板100的基板10一般为一金属薄板，当基板10的宽度和长度较大时，基板10局部容易发生晃动或翘曲，加强板101、加强板挡板102可以使得基板10更加坚固，不易发生晃动或翘曲。
本实施例中，每一栏位110可以为一个托盘组成，也可以为多个托盘共同组成，包括两个以上托盘底板41以及两个托盘侧板42；任意两个相邻托盘底板41之间存在间隙，该间隙的宽度不能太大，也不能太小，一般为5mm-30mm，优选10mm、15mm或20mm，是为了避免相邻两个托盘40相互干扰；两个托盘侧板42分别安装至该栏位110的左右两侧。当该间隙的两边存在托盘侧板时，该间隙两边的两个托盘底板分别属于两个不同的栏位，若间隙宽度太小，两个栏位中的商品就可能互相接触、彼此干扰，影响重量传感器的数据精度。当该间隙的两边不存在托盘侧板时，该间隙两边的两个托盘底板属于同一个栏位，该间隙位于该栏位底部，若间隙宽度太大，浪费空间较多，影响托盘的布局。
当一个货架上摆放的所有货品都为宽度较小的货品时，用一个托盘形成一个栏位，例如一个托盘10cm宽，可用以摆放宽度为8cm的商品。当货架上需要摆放宽度较大货品时，经营者可以直接拆卸分别属于两个托盘40的两个相邻的托盘侧板42，使得相邻的两个托盘40组成一个栏位110，使得栏位宽度变为原来的2倍；进一步地，经营者可以拆卸多个托盘侧板42，使得相邻的多个托盘40组成一个栏位110，使得栏位宽度变为原来的多倍。托盘侧板42的拆卸和安装简单方便，用户可以直接在货架板上操作，无需将托盘从货架上拆下，便于推广应用。栏位宽度被调整后，该栏位对应的重量传感器数量也会发生变化，若一个栏位的托盘的数量由一个变成多个，多个托盘下方的重量传感器采集到的多个重量感应值的总和为该栏位的实时重量感应值，工作人员需要通过键盘或手持 终端在计算机系统中修改设置参数，以确保计算机系统中该栏位的实时重量感应值真实可信。例如，货架的某一层货架板上设有编号为A1、A2、A3、A4、A5、A6的六个托盘，下方分别设有编号为B1、B2、B3、B4、B5、B6的六个重量传感器，原来每一托盘分别形成一个栏位，计算机同时可以获取六个实时重量值，分别为每一栏位的重量感应值。若将相邻的三个托盘合并成一个栏位，托盘A1、A2、A3形成第一栏位，托盘A4、A5、A6形成第二栏位，需要在计算机系统中更改设置参数，对传感器B1、B2、B3采集的实时数据求和处理，获得的总重量值即为第一栏位的重量感应值；对传感器B4、B5、B6采集的实时数据求和处理，获得的总重量值即为第二栏位的重量感应值。
一般来说，尺寸更大的货品和托盘，重量都会更重，如果一个加宽的栏位下方仅设置一个重量传感器，对传感器的量程要求就会很高，例如0-20千克，这类传感器普遍价格很高，一家便利店需要大量重量传感器，成本会高得惊人。本实施例中，在每一托盘下方设有一个重量传感器，当多个托盘组成一个栏位时，一个栏位的重量被分布到多个重量传感器上，托盘和支架占用量程较少，便利店经营者可以使用量程较小、价格较低的重量传感器，无需调整重量传感器位置，也无需使用夹具，可以有效降低硬件成本和提升测量精度。
本实施例通过插拔托盘侧板42调整栏位110的宽度，可用以解决现有货架存在的栏位宽度单一、管理成本较高的技术问题；另一方面本实施例不用拆卸下托盘40及重量传感器30即可实现栏位110大小的调节，操作简单方便，而且不用设置便于拆卸的夹具等结构，货架的重量轻、体积小、成本低。
本实施例中，货架板100还包括数据处理设备(未图示)，数据处理设备连接至多个重量传感器30。重量传感器30用于实时采集每一栏位110的实时重量值，实时重量值为每一栏位110下方的至少一重量传感器30实时数值的总和，也即每一时刻下，托盘、支架及托盘上货品的总重量。在完成重量传感器30的采集频率和时间间隔的设置之后，每一栏位110相邻两次的实时重量值的差值即为该栏位中发生变动的货品重量值，预先存储每一栏位货品的单品重量值，数据处理设备由此可以计算出被取走或被放回的货品的数量。
最佳实施方式(实施例2)
如图8所示，在本实施例2中包含了实施例1的全部技术特征，其区别 在于，在实施例2中还包括接近传感器50，连接至数据处理设备(如计算机系统)，接近传感器50设于所述基板10上表面；每一接近传感器50与一第三安装孔413和/或一第四安装孔414相对设置。所述数据处理设备用于实时采集货架板上每一侧板的位置，获取每一栏位与至少一重量传感器的对应关系。
每一托盘下方的左右两侧分别设有至少一个接近传感器50，可以位于前后两端的支架20下方，也可以位于托盘底板左右侧边的中部的下方。托盘底板左右两侧的托盘侧板42被移除或被安装时，都可以被接近传感器50感应到。当第三安装孔413或第四安装孔414内设有侧板卡块421时，接近传感器50与一侧板卡块421相对设置，从而可以判断此处存在托盘侧板42；当某一托盘侧板42被取走时，接近传感器50感应不到侧板42，因此，计算机系统可以根据每一个接近传感器50的感应信号判断留存在货架板上的托盘侧板42的位置，从而明确每一个栏位110的位置和宽度，计算机系统可以由此找出每一个栏位对应的重量传感器的位置和数量，设置每一个栏位对应的实时重量值为该栏位下方的至少一重量传感器采集到的至少一实时数值的总和。也就是说，工作人员手动拆除或安装托盘侧板后，计算机系统可以同步获取每一栏位的位置、宽度及其对应的重量感应值，进而可以根据重量感应值的变化监控该栏位的商品数量变化，无需用人力重新设置栏位的位置、重量感应值，实现了计算机系统的全自动化控制。
接近传感器50优选为霍尔传感器，此时，侧板卡块421整体或部分由磁性材料制成。例如，侧板卡块421的表面设有含磁性材料的磁性层。当侧板卡块421被插入至第三安装孔413或第四安装孔414时，霍尔传感器50与侧板卡块421的距离小于霍尔传感器的感应距离(如10mm)，计算机可以判断该传感器对应的位置是否存在侧板42。
每一托盘40下方设有至少两个接近传感器50，用于感应托盘40的左右两侧是否存在侧板42，可以位于前后两端的支架20下方，也可以位于感应托盘40中部的下方。
在一实施例中，如图9所示，所有接近传感器50被排列在一条直线上。可以将所有接近传感器50排列在托盘前板43或托盘后板44下方所对应的一条直线上。
在另一实施例中，也可以在每一侧板42下方的基板上对应设置两个以上 接近传感器50，例如，可以将接近传感器50排列在托盘前板43下方和托盘后板44下方的两条直线上。
如图10所示，在另一实施例中，优选地，托盘底板41为矩形，每一托盘底板41的两个角落下方的基板上分别设有一个接近传感器，每一接近传感器50与一第三安装孔413和/或一第四安装孔414相对设置。托盘底板41下方的两个接近传感器50的连线在该托盘底板41的投影位于该托盘底板41的对角线上。同理，可按照图10的方式将在对应托盘前板43位置的接近传感器50与在对应托盘后板44位置的接近传感器50的位置对换，同样使得两个接近传感器50的连线在该托盘底板41的投影位于该托盘底板41的对角线上。
在其他实施例中，接近传感器50还可以包括距离传感器，也称位移传感器，如红外测距传感器、激光测距传感器或超声波测距传感器，等等。计算机系统可以通过距离传感器检测与侧板卡块421的实际距离判断货架上留存的托盘侧板42的位置，从而计算出栏位的位置和宽度，并找出每一栏位对应的重量传感器的位置和数量。
每一接近传感器50用以识别一个托盘侧板，为了防止接近传感器50误识别到位置相邻的、无对应关系的另一侧板卡块421，任意两个相邻托盘40之间存在间隙，且该间隙大于等于霍尔传感器的感应距离10mm从而避免误识别。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
