Description

[Technical field]

[0001] The present invention relates to a weighing device suitable for volume sales, which allows customers to purchase only the amount they desire, and a shelf therefor. [Background technology]

[0002] In recent years, attention has been focused on bulk sales, which provide retailers with bundled goods for bulk purchase to be sold to businesses. When conducting bulk sales, goods supply devices are used that allow customers to purchase only the amount they desire. These devices are so-called bulk dispensers, such as cereal dispensers, nut dispensers, candy dispensers, and snack dispensers (for example, see Non-Patent Document 1). [Prior art documents] [Non-patent literature]

[0003] [Non-Patent Document 1] “DH50-FF CEREAL DISPENSER”, [online], [searched on July 21, 2023], Internet, <URL:https: / / www.idm-dispenser.com / collections / cereal-dispenser / products / dh50-ff-cereal-dispenser>

[0004] In addition, some item supply devices are configured as item sales devices suitable for a sales format in which items released from a bulk dispenser are stored in paper containers (tares) prepared by the store, pricing labels issued after weighing are attached to the containers, and the items are paid for at the cash register.

[0005] Figure 13 shows such an item sales device, in which any desired amount of item can be taken out of multiple storage sections (cylinders) by operating the supply operation section of the storage section corresponding to the desired type of item, and the item is sold by weight (measured sale). Summary of the Invention [Problem to be solved by the invention]

[0006] As shown in Fig. 13, when multiple types of goods are displayed, it is natural that some customers would like to purchase several different kinds of these multiple types of goods. However, in order to purchase goods at such a weighing sale, it is inconvenient because it is necessary to weigh each product discharged from the dispenser by individually placing it in a container or bag, and if a customer is confused about how to operate each weighing device, there is a problem that the customer cannot purchase the appropriate amount out of consideration for the next customer, etc. Even if only one type of goods is purchased, it is not entirely without the problem of inconvenience in placing the goods discharged from the dispenser in a container and weighing it.

[0007] In view of the above problems, an object of the present invention is to provide a weighing device and a shelf therefor that are easy to use. [Means for solving the problem]

[0008] The weighing device of the present invention has at least the following configuration. This is a subtraction-type weighing device that discharges items from a storage container and calculates the weight of the discharged items, and is characterized in that it comprises a main body that incorporates a weighing unit, a weighing pan provided on the main body, and an extension portion that extends upward from the weighing pan, and the storage container is removably attached to the extension portion. The shelf of the present invention has at least the following configuration. The shelf comprises a main body incorporating a weighing unit, a weighing pan provided on the main body, and an extension extending upward from the weighing pan, and the extension is a shelf for storing a weighing device to which a storage container for items is removably attached, the shelf comprising a shelf plate on which the weighing device is placed, and a weighing pan covering member that covers the weighing pan of the weighing device to prevent other items from interfering with the weighing pan. Effect of the Invention

[0009] According to the present invention, it is possible to provide a weighing device and a shelf therefor that are easy to use when selling by weight (volume sales). [Brief description of the drawings]

[0011] An example of an embodiment of a weighing device and a shelf according to the present invention will be described below with reference to the drawings. However, the drawings below have been created for the purpose of explanation, and in order to make the drawings easier to understand, some components not necessary for the explanation may not be shown intentionally. In addition, some components may be shown intentionally large or small for the purpose of explanation, and the drawings are not drawn to an accurate scale. In the following description, the same reference numerals in different drawings indicate parts with the same function, and duplicate descriptions in each drawing will be omitted as appropriate.

[0012] First Embodiment (Weighting device and shelf configuration) Fig. 1 is a perspective view showing the appearance of a plurality of weighing devices according to the first embodiment of the present invention stored on a dedicated shelf. Fig. 2 is a view showing the appearance of a plurality of weighing devices according to the first embodiment of the present invention stored on a dedicated shelf, where (a) is a front view and (b) is a cross-sectional view taken along line AA in (a). Fig. 3 is a view showing the appearance of the weighing device according to the first embodiment of the present invention, where (a) is a perspective view, (b) is an enlarged view of the display unit, and (c) is a perspective view showing a modified example.

[0013] The weighing device 100 according to the first embodiment of the present invention shown in Figs. 1 and 2 is a subtraction-type weighing device for purchasing products stored in a storage container 3 placed on a scale, and calculates the price by calculating the weight of the product removed from the total weight. Generally, a plurality of weighing devices 100 are installed on a dedicated shelf for use, and six weighing devices are installed here. The dedicated shelf is configured to have at least two rows of shelves, one above the other, laid horizontally. The lower shelf is a first shelf 6 on which the weighing devices 100 are placed, and the upper shelf is a second shelf 7 for covering the weighing dishes 12 (see Fig. 2) of the weighing devices 100 to prevent other items from interfering with the weighing dishes 12. Here, the second shelf 7 is a single continuous plate, but one weighing dish covering member may be provided for each weighing device 100. Alternatively, two or three weighing dish covering members may be provided. 1 and 2, a goods vending device 5 of a different type (selling by the cup) from the weighing device 100 according to the first embodiment of the present invention is placed under a first shelf 6. A console 4 is installed to the right of the weighing device 100 and goods vending device 5. The console (operating table) 4 has a printer function unit that issues payment labels printed with information for selling goods provided to customers.

[0014] 3 is a container for storing goods, but it is not required to transfer purchased goods to the storage container body 31 in order to stock them, and it is a distribution container that is wholesaled as is, so it can also be considered as a goods storage distribution container. In other words, the seller attaches a distribution container (commuting container) for the bulk goods that he or she has purchased to the weighing device 100.

[0015] As a specific structure, as shown in Fig. 3(a), the weighing device 100 comprises a main body 1 incorporating a weighing unit 11 serving as a load cell, a weighing dish 12 provided on the main body 1 (usually serving as the top plate of the main body 1), and an extension part 2 extending upward from the weighing dish 12, with a storage container 3 removably attached to the extension part 2. The storage container 3 comprises a storage container main body 31, a discharge operation part 33, and an article discharge part 34. Note that, although the weighing dish 12 is shown extending to the front end of the main body in the figure, it is also possible to configure the weighing dish 12 only below the extension part 2, with the front side being a rigid structure that is not affected by weight.

[0016] As shown in FIG. 3(a), the display unit 13 is obliquely provided at the front of the main body 1 at an angle that is easy for the operator to see. FIG. 3(b) is an enlarged view (front view) of the display unit. The display unit 13 is provided with a discharged weight display unit 131, a total weight display unit 132, a unit price display unit 133, a monetary amount display unit 134, a scale status display unit 135, and an operation unit 136. The discharged weight display unit 131 calculates the weight of the items discharged by the internal process from the change in the total weight, and displays the resultant discharged weight. The total weight display unit 132 displays the total weight of the items, which includes the weights of the extension unit 2 and the storage container 3. Even if these weights are included, there is no effect on determining the discharged weight from the change in the total weight, and by doing so, the zero point adjustment of the scale is simplified. The unit price display unit 133 displays the unit price of the items of a predetermined weight (for example, per 1 g). The amount display unit 134 displays the amount calculated by multiplying the unit price by the discharged weight. The scale status display unit 135 indicates whether the weight measured by the scale is stable or not, for example by color; in this example, red indicates that the scale is unstable, and green indicates that the scale is stable. The operation unit 136 is an operation means for confirming the purchase, and is configured here so that the purchase is confirmed by touching an appropriate medium (for example, a membership card). The operation unit 136 may be configured with touch buttons.

[0017] 3(c) is a perspective view showing a modified example of the first embodiment, in which the shape and structure of the storage container, in particular the structure for detachably mounting the storage container, are different from those of the first embodiment, as will be described later.

[0018] 4 is an exploded view showing the function for enabling a storage container to be detachably attached to the extension part, i.e., the periphery of the attachment part, in the weighing device according to the first embodiment of the present invention. Specifically, an attachment 35 is inserted into components consisting of an attachment insertion slot 32, a discharge operation part 33, and an article discharge part 34. The attachment 35 functions as a joint between the article discharge part 34 and the storage container main body 31, and multiple types of attachments 35 are prepared. The composite body in which the article discharge part 34 and the storage container main body 31 are joined is attached to the attachment part 21 connected to the extension part 2.

[0019] The attachment 35 has an opening for connecting the storage container body 31 and the article discharge section 34 in communication with each other. As shown in the figure, the attachment 35 is configured so that it can be attached and detached by being pushed into the attachment insertion slot 32 provided on the opposite side of the article discharge section 34. The reason for this is that there are storage container bodies 31 with various sizes of apertures and shapes to correspond to the large variety of products, and multiple types of attachments 35 with different aperture sizes and shapes are prepared and interchangeable to correspond to these multiple types of storage container bodies 31.

[0020] Here, the shape of the opening is substantially circular, and a plurality of protrusions 351 are provided at a predetermined interval in the circumferential direction of the inner circumference so that the opening can be tightened around the screw of the storage container body 31 (in FIG. 4, not all of the protrusions 351 are drawn with leader lines, and some are omitted from the illustration). The connection with the storage container body 31 is made like a so-called twist cap. However, it is not essential, and instead of the protrusions 351, a female thread can be cut on the inner circumference of the opening to form a configuration like a screw cap. It is preferable to prepare the shape of the opening of the attachment 35 according to whether the cap of the storage container body 31 to be actually connected is a twist cap or a screw cap, but it is also possible to use the protrusions 351 to correspond to all of them. However, it is necessary to prepare a plurality of different opening sizes of the attachment 35 according to the opening size of the storage container body 31.

[0021] An attachment insertion slot 32 into which an attachment 35 can be inserted is provided at the upper end of the article discharge section 34. Thus, the attachment 35 serves to connect the article discharge section 34 and the storage container main body 31 to communicate with each other. Since the storage container main body 31 is connected to the article discharge section 34 via the attachment 35 and is integrated, the extension section 2 functions to transmit the total weight of the articles stored in the storage container main body 31, the entire weight of the storage container 3, and the total weight of the extension section 2 to the weighing section 11 (load cell) built into the main body 1 via the weighing plate 12. Note that the portion of the weighing plate 12 forward of the portion from which the extension section 2 extends is covered by the second shelf plate 7, so that it is prevented that some other member is inadvertently loaded on the weighing plate 12, which would cause an error in the measured value.

[0022] The article discharge section 34 is manufactured by resin molding or the like, and is equipped with a discharge operation section 33 which the operator can rotate, a temporary storage section (not shown) which rotates inside the main body of the article discharge section 34 in conjunction with the rotation operation of the discharge operation section 33, and a discharge outlet which is open in only one direction and can store a specified volume of articles.

[0023] As shown in FIG. 4, in the first embodiment, the storage container 3 attached to the extension portion 2 is configured such that the storage container body 31 and the article discharge portion 34 are separated. This is based on the requirement that a distribution container (commutable container) for bulk products should be used as is. Otherwise, if the transfer of articles from the commutable container is not hindered, the storage portion and the discharge portion for articles can be integrated into one structure. FIG. 3(c) is a perspective view showing such a modified example, and the shape and structure of the storage container, particularly the structure for detachably attaching the storage container, are different from those of the first embodiment. In this modified example, the height position at which the storage container is installed is adjustable. The specific structure will be described in the description of the second embodiment, which is common to the second embodiment described later.

[0024] (System configuration consisting of measuring devices and other devices) FIG. 5 shows a system A consisting of a weighing device 100 according to an embodiment of the present invention, a goods sales device 5, and a console 4, with FIG. 5(a) showing the system configuration and FIG. 5(b) showing the hardware configuration of the weighing device 100. The console 4 (operation console) has a printer function unit that issues a billing label on which information for selling goods provided to a customer is printed, but the rest of the configuration is the same as the system configuration normally provided in a general-purpose PC, such as a CPU, a memory device (ROM and RAM) connected to the CPU by a bus, a storage device, a display means, a communication means, and an operation input means, so the hardware configuration is not shown. In other words, it is possible to configure the console 4 as a general-purpose PC or a tablet by providing an external printer function.

[0025] As shown in FIG. 5(a), in system A, multiple weighing devices 100 and goods sales devices 5 are connected to a console 4 via a network. In the figure, the console 4 is shown as a single unit, but it is also possible to configure it with multiple units. Here, the network is an in-store LAN, and connections are made via wired or wireless connections. Although not shown in the figure, a store controller, POS, and clerk terminals (transaction status management devices: monitoring terminals, mobile terminals, etc.) may also be connected, and master-related processing may be configured to be realized by SaaS (Software as a Service).

[0026] FIG. 5(b) is a hardware configuration diagram of the weighing device 100. As shown in the figure, the weighing device 100 includes a control unit (CPU), and storage devices such as a RAM and a ROM. The control unit (CPU) comprehensively controls each component of the weighing device 100. The control unit executes a control program, for example, to cause a computer to realize each function of the weighing device 100. The ROM stores the control program and the like. The control unit is connected to a display unit consisting of the discharge weight display unit 131, total weight display unit 132, unit price display unit 133, amount display unit 134, scale status display unit 135, etc., as described above, via an interface circuit, and is also connected to a communication unit and the weighing unit 11.

[0027] The communication unit is realized by one or more communication means for realizing a connection with the console 4. For example, the mutual connection with the console 4 is realized by a wired or wireless LAN. When the communication unit is realized by a wired LAN, the power supply of the weighing device 100 may be secured by POE (Power over Ethernet) supply from the console 4 connected to an external power supply. However, this does not prevent the weighing device 100 from being directly connected to an external power supply or being powered by an internal battery.

[0028] The weighing unit 11 measures the weight of an item. More specifically, the weighing unit 11 is composed of a detector and an AD converter (neither shown). The weighing unit 11 is realized by a load cell, and the AD converter converts an analog signal input from the load cell into a digital signal. In converting into a digital signal, a range in which the weight value can be appropriately acquired is set, and the zero point and the maximum weighing value are recorded. The value converted into digital data is displayed as the weight (weighing value) on the total weight display unit 132.

[0029] (Operation procedure and processing contents) With reference to Fig. 3, the operation procedure and the processing contents of the device when a customer purchases only the desired amount of products will be explained. The customer takes his / her own container or a bag or container provided, and operates the discharge operation unit 33 to put the products from the product discharge unit 34 into his / her own container, etc. At this time, the display unit 13 is configured to sequentially display the total weight, unit price, weight of the discharged products, and amount (unit price x weight) of the products.

[0030] While an item is being dispensed or immediately after it is dispensed, the displayed weight is not stable and the scale status display unit 135 is lit in red, but eventually, when the weight stabilizes, the scale status display unit 135 changes from red to green. After it turns green, the purchase is confirmed by operating the operation unit 136 on the lower right side of the display unit, specifically, by touching it with a membership card or by touching (or pressing) the touch button. Note that the control process is such that no reaction occurs when the light is red even if you perform a touch operation, but a reaction occurs when the light turns green.

[0031] After the operation of the operation unit 136, the information on the product to be purchased and the amount (unit price x weight) are output so that they can be confirmed on the console 4. By holding the membership card over the console 4, an operator indicating the product is displayed, and by touching the displayed operator, a label containing the product information is issued. This label can also be configured as a receipt. The customer takes the issued label and the product in the container to the payment machine to make the payment. As shown in Figs. 1 and 2, it is common for multiple weighing devices 100 to be installed to correspond to multiple different products, and the master is configured to link each weighing device to the product. As a specific operation, when the member's card or the like is touched on the standby screen on the console 4 displaying "Please touch the card", for example, if a signal indicating that the product has been released from the weighing device 100A containing almonds has been received, "almonds" will be displayed. When the customer confirms this and touches the "issuance receipt" button, a guide screen is displayed informing the customer that a receipt will be issued and that the receipt should be handed over to a staff member. In addition, the master stores the weight of the storage container 3 and the total weight of the extension portion 2, so that by monitoring the total weight at the time of purchase, it is possible to detect when the product is near the end and to notify this.

[0032] <Another embodiment> If one storage unit is provided on one scale as in the first embodiment, space is inevitably wasted. Therefore, it is possible to provide multiple storage units on one scale. FIG. 6 is a perspective view showing the appearance of a weighing device according to a second embodiment and a third embodiment of the present invention. FIG. 6(a) shows a second embodiment in which two storage units are provided on one scale, and FIG. 6(b) shows a third embodiment in which three storage units are provided on one scale. As is clear from the drawings, the problem of installation space is greatly improved.

[0033] Second Embodiment FIG. 7 is an explanatory diagram showing the appearance of a weighing device according to a second embodiment of the present invention, and is a perspective view with a part removed. As shown in FIG. 7, the weighing device 100A according to the second embodiment of the present invention includes a main body 1 incorporating a weighing unit 11 as a load cell, a weighing dish 12 provided on the main body 1, and an extension part 2A extending upward from the weighing dish 12, and two storage containers 3A are detachably attached to the extension part 2A via an attachment part 21A and a height adjustment part 22A. The height adjustment part 22A can be attached to a plurality of positions of different heights of the attachment part 21A by a urea screw or the like, and is configured to adjust the installation height of the storage container 3A. The modified example of the first embodiment described above is also height adjustable with a similar structure.

[0034] In the first embodiment, the storage container body and the article discharge unit are separate, but in the second embodiment, the article discharge unit and the operation unit are integrally provided in the storage container 3A. The returnable container cannot be used as it is, and the work of transferring the articles from the returnable container is required, but the labor-saving of the installation space is a great merit for the store.

[0035] (Operation procedure and processing contents) In this way, according to the second embodiment, the problem of installation space that the first embodiment had is solved. However, a new problem arises in that sales management of individual items becomes complicated. Therefore, in a system equipped with the second embodiment, each storage container 3A, 3A is linked to the product in the master. To avoid complicated processing, although different products are stored in the two storage containers 3A, 3A, the unit price of the products is set so that the same products are included in one set.

[0036] The operation procedure and processing contents in the system having the second embodiment configured as described above will be described below. The operations from when the customer puts the product into his / her own container, confirms that the scale has stabilized on the display unit 13 of the weighing device 100A, until the customer confirms the purchase are the same as in the first embodiment. After that, the operations performed on the console 4 will be described. Figure 8 is an explanatory diagram showing the transition of the operation display screen of the console used together with the weighing device according to the second embodiment of the present invention.

[0037] After operating the weighing device 100A, the product information and the price (unit price x weight) to be purchased are output to the console 4 so that they can be confirmed. By holding the membership card over the console 4, an operator indicating the product is displayed, and by touching the displayed operator, a label containing the product information is issued. Specifically, the member card or the like is touched on the standby screen on the console 4 displaying "Please touch your card". Then, the screen of the console 4 displays a screen asking which product to purchase, since it has received a signal from the weighing device 100A, which contains peanuts and almonds in the double storage container 3A, that one of the products has been released. In this case, the customer has purchased almonds, so "almonds" is touched. Note that the unit prices of peanuts and almonds are set to the same, so even if the wrong one is selected, neither the store nor the customer will suffer any economic disadvantage. Next, when the customer confirms that the selected "almonds" is displayed and touches the "issuance receipt" button, a screen appears informing the customer that a receipt will be issued and that the receipt should be handed over to a staff member. In this way, the customer can smoothly carry out their shopping, and the store can manage product sales.

[0038] Furthermore, if a sensor is provided on each of the two storage containers 3A, 3A, the management of products can be simplified. That is, two sensor IDs of the sensors provided on each operation unit are linked to the respective product information, and when the right operation unit is turned, the right product information and unit price are output to the weighing device 100A, and when the left operation unit is turned, the left product information and unit price are output to the weighing device 100A, and the weighing device 100A that receives the information outputs the information and the measured weight so that the upper device or console 4 can call it. By configuring in this way, even if two different products are stored in the weighing device 100A, single product management can be performed without any problems. That is, even if products with different unit prices are stored in the two storage containers 3A, 3A of one weighing device 100A, the store can manage them without any problems.

[0039] Third embodiment FIG. 9 is an explanatory diagram showing the appearance of a weighing device according to a third embodiment of the present invention, and is a perspective view with a part removed. As shown in FIG. 9, the weighing device 100B according to the third embodiment of the present invention includes a main body 1 incorporating a weighing unit 11 as a load cell, a weighing dish 12 provided on the main body 1, and an extension part 2B extending upward from the weighing dish 12, and three storage containers 3B are detachably attached to the extension part 2B via an attachment part 21B and a height adjustment part 22B. The height adjustment part 22B can be attached to a plurality of positions of different heights of the attachment part 21B by a urea screw or the like, and is configured to adjust the installation height of the storage containers 3B. In this way, in the third embodiment, it is possible to further promote labor-saving of the installation space.

[0040] (Fourth embodiment) Fig. 10 is a perspective view showing the appearance of a weighing device according to a fourth embodiment of the present invention. As shown in Fig. 10, the weighing devices 100C and 100C' according to the fourth embodiment of the present invention include a main body 1 incorporating a weighing unit 11 as a load cell, a weighing dish 12 provided on the main body 1, and an extension part 2C extending upward from the weighing dish 12, and one storage container 3C or two storage containers 3C, 3C are placed on the extension part 2C. In addition, a display part 13 is provided in front of the main body 1 via an expandable part EX. As shown in the figure, the weighing device 100C includes one storage container 3C, and the weighing device 100C' includes two storage containers 3C, 3C.

[0041] The fourth embodiment differs from the first to third embodiments shown so far in that the extension portion 2C has a greater depth than those shown so far and is placed on almost the entire weighing pan, so that it is stable from the viewpoint of placing the entire device and from the viewpoint of measurement. As a specific structure, a U-shaped metal plate 2C1 is provided at the rear end of the upper surface of the extension portion 2C, and the rear end of the storage container 3C is hooked onto this portion for installation. In addition, a restricting portion (2C2) is provided on the upper surface of the extension portion 2C, and is configured to restrict left-right deviation of the storage container 3C. As shown in FIG. 10, in a type in which only one storage container 3C is arranged, the restricting portion 2C2 is arranged at two locations on both the left and right sides of the storage container 3C, and in a type in which two storage containers 3C are arranged, the restricting portion 2C2 is arranged at a total of three locations, two locations on both the left and right ends of the storage containers 3C, 3C combined, and one location between the storage containers.

[0042] Although the extension portion 2C is placed on almost the entire weighing dish, the upper surface of the weighing dish is exposed, albeit slightly, as shown in Fig. 10. Therefore, the fourth embodiment is similar to the previous embodiments in that this portion is covered with a shelf. However, the display unit 13 can be extended and retracted forward by the extension portion EX, allowing for flexible settings according to the installation site.

[0043] FIG. 11 shows an example of a layout in which two types of weighing devices 100C and 100C' of the fourth embodiment are efficiently arranged. The weighing device 100C' has two storage containers 3C, 3C, so it protrudes from the width of the weighing dish on the left and right. Therefore, by arranging the weighing devices 100C and 100C' alternately on the left and right, it is possible to avoid the occurrence of wasted space. When installing the weighing devices with the left and right width narrowed in this way, it is efficient to make the second shelf board 7 (not shown in FIG. 11) a single continuous board that spans multiple weighing devices. However, when the weighing devices are installed at a distance, a weighing dish covering member that covers the weighing dish for each weighing device may be provided. Alternatively, a weighing dish covering member may be provided for two or three weighing devices.

[0044] In the fourth embodiment, further improvements are made for stable weighing. FIG. 12 is an exploded perspective view of the weighing device 100C'. The weighing unit 11 (load cell), which has not been visible so far because it is built into the main body 1, is clearly shown in FIG. 12. A notable improvement is the vibration-proof materials 111 provided at the four corners of the weighing unit 11. Since the weight of the storage container (dispenser) is larger than the original weighing target of the weighing pan, the scale's scale interval fluctuates and it is difficult to stabilize the scale. However, by providing the vibration-proof materials 111, it is possible to absorb the fluctuation of the scale interval. The vibration-proof materials 111 may be provided between the weighing pan and the extension portion.

[0045] Returning to FIG. 1 and FIG. 2, in the space for bulk sales, in addition to the weighing device 100 according to the embodiment of the present invention, a goods sales device 5 is also installed. The goods sales device 5 is a subtraction processing type weighing device that calculates the weight scooped by a cup or spoon from the total weight placed on the weighing plate and calculates the selling price from the unit price, thereby enabling fixed-quantity sales. In the case of the subtraction type, after the goods are moved to a scooping container, the data required for fixed-quantity sales is transmitted by operating a button on the condition that the weight is stable. By using multiple sales methods such as cup sales and single spoon sales in combination, it is possible to deal with various types of goods, and the possibility of development in the sales floor is increased. When it comes to subtraction type weighing devices, such cup sales and single spoon sales were typical. And, in a device that releases and supplies any amount of goods by rotating an operating part such as a dial, the only idea was to prepare a weighing device separately from the release and supply device, as shown in FIG. 13. According to the present invention, a completely new idea makes it possible to realize easy-to-use bulk sales.

[0046] <Summary of the embodiment> [Technical field] The present invention relates to a weighing device suitable for volume sales, which allows customers to purchase only the amount they desire, and a shelf therefor. [Background technology] In recent years, attention has been focused on bulk sales, which provide retailers with bundled goods for bulk purchase to be sold to businesses. When conducting bulk sales, goods supply devices are used that allow customers to purchase only the amount they desire. These devices are so-called bulk dispensers, such as cereal dispensers, nut dispensers, candy dispensers, and snack dispensers (for example, see Non-Patent Document 1). [Prior art document] [Non-patent literature] [Non-patent literature 1] “DH50-FF CEREAL DISPENSER”, [online], [searched on July 21, 2023], Internet, <URL:https: / / www.idm-dispenser.com / collections / cereal-dispenser / products / dh50-ff-cereal-dispenser> In addition, some item supply devices are configured as item sales devices suitable for a sales format in which items released from a bulk dispenser are stored in paper containers (tares) prepared by the store, pricing labels issued after weighing are attached to the containers, and the items are paid for at the cash register. Figure 13 shows such an item sales device, in which any desired amount of item can be taken out of multiple storage sections (cylinders) by operating the supply operation section of the storage section corresponding to the desired type of item, and the item is sold by weight (measured sale). [Summary of the invention] [Problem to be solved by the invention] As shown in Fig. 13, when multiple types of goods are displayed, it is natural that some customers would like to purchase several different kinds of these multiple types of goods. However, in order to purchase goods at such a weighing sale, it is inconvenient because it is necessary to weigh each product discharged from the dispenser by individually placing it in a container or bag, and if a customer is confused about how to operate each weighing device, there is a problem that the customer cannot purchase the appropriate amount out of consideration for the next customer, etc. Even if only one type of goods is purchased, it is not entirely without the problem of inconvenience in placing the goods discharged from the dispenser in a container and weighing it. In view of the above problems, an object of the present invention is to provide a weighing device and a shelf therefor that are easy to use. [Means for solving the problem] (1) As described above, one aspect of this embodiment is a subtraction-type weighing device 100, 100A, 100B, 100C that discharges items from storage containers 3, 3A, 3B, 3C and calculates the weight of the discharged items, and is characterized in that it comprises a main body 1 having a built-in weighing section 11, a weighing pan 12 provided on the main body 1, and extension portions 2, 2A, 2B, 2C extending upward from the weighing pan 12, and the storage containers 3, 3A, 3B, 3C are removably attached to the extension portions 2, 2A, 2B, 2C.

[0047] According to the above configuration, it is possible to provide a weighing device that is easy to use and eliminates the need to separately weigh the items after they have been packed into the container.

[0048] (2) One aspect of this embodiment is characterized in that in the weighing devices 100, 100A, 100B, and 100C described in (1), a vibration-proof material 111 is provided on the upper surface or the lower surface of the weighing dish 12.

[0049] According to the above configuration, fluctuations in scale interval can be absorbed.

[0050] (3) One aspect of this embodiment is characterized in that the weighing device 100, 100A, 100B, 100C described in (1) or (2) is provided with a display means 13 that displays at least the total weight of goods stored in the storage containers 3, 3A, 3B, 3C and the discharged weight of goods discharged from the storage containers 3, 3A, 3B, 3C, and the total weight of goods includes the weight of the extension portions 2, 2A, 2B, 2C and the storage containers 3, 3A, 3B, 3C.

[0051] According to the above-mentioned configuration, the zero point can be adjusted in the same way as usual (regardless of the extension portion or the storage container), which is convenient.

[0052] (4) One aspect of this embodiment is a shelf for storing the weighing devices 100, 100A, 100B, 100C described in (1) or (2), characterized in that it includes a shelf board 6 on which the weighing devices 100, 100A, 100B, 100C are placed, and a weighing plate cover member that covers the weighing plates 12 of the weighing devices 100, 100A, 100B, 100C to prevent other items from interfering with the weighing plates 12.

[0053] According to the above-mentioned configuration, it is possible to realize a usage environment in which any other member is not inadvertently placed on the weighing dish 12, which would cause an error in the measured value.

[0054] (5) One aspect of this embodiment is the shelf 6 according to (4), characterized in that the covering member is a second shelf that continuously covers the weighing dishes of a plurality of weighing devices.

[0055] According to the above configuration, when multiple weighing devices are placed close to each other, it is possible to efficiently realize an operating environment in which there is no risk of other components being inadvertently placed on the weighing pan 12, causing errors in the measured values.

[0056] The weighing device and shelf according to the embodiments of the present invention have been described in detail above with reference to the drawings.
