Description

The present invention relates to a mobile display and sales device that is suitable for use in stores such as convenience stores.

Conventionally, store display shelves were fixed between the floor and ceiling of the sales floor in a store to display products. In this case, because it was necessary to display products on fixed shelves within reach of consumers, only display shelves with a height of about 180 cm from the floor were manufactured. This made it difficult for consumers to identify what products were displayed where, and there was wasted space between the top of the display shelf and the ceiling of the store building, which led to issues such as the sales floor space in the store not being used efficiently and the need for a separate storage space for products.

To solve the above problems, for example, as shown in Figures 1 and 2, a mobile lifting display vending machine has been proposed in which several chain wheels (6) are fixed in parallel on the left and right, a chain (2) is wound around them and connected endlessly, display baskets (1) are attached to the chain (2) at appropriate intervals, and the connection part (A) of the display basket (1) to the chain (2) is a round pin that can rotate. By rotating the chain (2) using the action of a prime mover (4) and a transmission device (5), the display basket (1) can be displayed while moving in the direction of the arrow in Figure 1 (see, for example, Patent Document 1).

Japanese Utility Model Application Publication No. 59-189574

According to the above proposal, the space between the top of the display shelves and the store ceiling can be effectively utilized, and the amount of products that can be displayed can be increased compared to the past.

The number of storage boxes is not particularly limited as long as it can be attached to the endless conveyor, but is preferably 10 or more, and more preferably 15 or more. Each storage box is marked with a unique number, and the products stored in the storage box and their descriptions are registered in advance according to the storage box number and managed by the control unit.
The storage box can store not only one product but also multiple products. When multiple products are stored, it is preferable that partitions are provided in the storage box. For example, when four products are stored, three partitions are provided in the vertical or horizontal direction. The positions and number of partitions can be adjusted according to the shape and size of the products.

It is preferable that the storage box has a product presence/absence sensor that detects when all products have been removed from the storage box and it is empty. Examples of the product presence/absence sensor include a photoelectric sensor and a mass sensor.

The storage box has an attachment section and a storage section. It is attached to the endless conveyor by the attachment section, and stores products in the storage section.

The storage box preferably has a door that can be opened and closed. Having a door is suitable for cases where it is better to seal certain types of products, and also prevents products from falling out when the storage box is moved. The door is preferably transparent so that the products inside the storage box can be recognized.
If the storage box has a door, the door is opened to put in and take out the product. A safety confirmation sensor is provided on the storage box so that the power source is not operated if the door is open.
The storage boxes are labeled with unique storage box numbers to facilitate easy selection by consumers.

The products to be stored in the storage box are not particularly limited and can be selected appropriately depending on the purpose, and examples include food and beverages, confectionery, clothing, toiletries, oral care products, supplements, stationery, toys, small electrical appliances, etc.

<Endless conveyor>
The endless conveyor is looped around a first sprocket and a second sprocket, and serves as a means for attaching and moving a storage box.
The endless conveying body is not particularly limited and may be appropriately selected depending on the purpose, and examples thereof include an endless chain, an endless belt, etc. Among these, an endless chain is preferable from the viewpoints of durability and cost.
It is preferable from the viewpoint of simplifying the structure to extend one end of each of the pins at intervals among the pins in each chain unit that constitutes the endless chain, and to attach the storage box to the extension of the pin.

There are no particular limitations on the first sprocket and the second sprocket as long as they are capable of transmitting rotational power to the endless conveyor, and they can be appropriately selected depending on the purpose.
The first sprocket and the second sprocket are formed in an annular shape, and have gear portions on their outer circumferential surfaces that can mesh with an endless conveying body.
It is preferable that the first sprocket is arranged in a pair at the top of the mobile display and sales device (the ceiling side of the store), and the second sprocket is arranged in a pair at the bottom of the mobile display and sales device (the floor side of the store).

<Product removal sensor>
The product removal sensor detects the removal of a product from the storage box. Information on the name of the product stored in the storage box, the contents of the product, etc. is input in advance by reading a barcode on the operation unit, manually input, etc., and stored in the recording unit.
By detecting the product removal sensor, the number of each product (sales amount) that a consumer removes (purchases) from a storage box during a certain period of time can be calculated.
The product removal sensor is not particularly limited as long as it can detect the removal of a product from the storage box, and can be appropriately selected, for example, a combination of a sensor dog and a proximity sensor, etc. By combining a sensor dog and a proximity sensor, it is possible to detect the removal of each product even when multiple products are stored in the storage box.

<Control Unit>
The control unit can be configured with hardware such as a circuit device that realizes various functions of the mobile display and sales device of the present invention, and can also be configured with, for example, a dedicated control board, a calculation device such as an MCU (Micro Controller Unit) or a CPU (Central Processing Unit), and software executed on the calculation device.
The control unit executes various processes based on information from various sensors such as a product removal sensor, a product presence sensor, and a safety confirmation sensor, as well as input information from the operation unit, and controls the overall operation of the mobile display and sales device.

The control unit calculates the sales volume of each product for a certain period based on information from the product removal sensor, and performs a process of moving the storage box storing the product with a high sales volume to a position where the product can be easily seen by consumers. This allows the product with a high sales volume to be displayed in a position where the product can be easily seen by consumers (a position where the product is likely to catch the consumer's eye), thereby increasing the sales of the product.
The sales amount of each product can be calculated by counting the electrical signals from the product removal sensor for a certain period of time, such as one week or one month.
The sales amount is the number of purchases of the product or the sales amount of the product, and is determined taking into consideration the number of products in stock. In other words, even if the sales amount of a product is high, if the product is out of stock, the product is not selected, and a process is performed to select the product with the next highest sales amount.
The position where the consumer can easily see is determined based on the position of the consumer's eyes and differs depending on the type of store and the age group of the consumer, but for example, a position of 150 cm±30 cm from the floor is preferable.
For example, the storage boxes housing the first and second most popular weekly sales items can be adjusted to be positioned to the left and right at a height of 150 cm from the floor.
The method of adjusting the display position of the storage boxes to a position that is easy for consumers to see is to automatically adjust the position by the control unit when there is no replacement of products in the storage boxes, and when it is necessary to replace products in the storage boxes, the store clerk manually replaces the products and then automatically adjusts the position.

When an empty storage box is generated after all products have been removed based on information from the product presence/absence sensor, the control unit moves the empty storage box to a product storage position and notifies a store clerk that products need to be stored in the box, thereby enabling products to be quickly replenished in the empty storage box.
The control unit adjusts the movement of the storage box to the product storage position in the shortest time possible.
The product storage position is not particularly limited as long as it is a position where the store clerk can easily store the products in the storage box, but a position of 100 cm±30 cm from the floor surface is preferable.
Methods for contacting the store clerk include, for example, a voice notification, a warning displayed on the cash register terminal screen, and a call to a mobile terminal.

When the consumer inputs the storage box number selected by the consumer into the operation unit, the control unit performs a process of displaying the product name and product description stored in the storage box on the display panel of the operation unit. This makes it easier for the consumer to select a product. The product name and product description stored in the storage box are previously input by barcode reading or manual input by the operation unit and stored in the recording unit.
When a consumer inputs a storage box number into the operation unit and presses a purchase button on the operation unit, the control unit performs a process of moving the corresponding storage box to a product removal position. This makes it easy for the consumer to pick up the product. The movement of the storage box to the product removal position is adjusted so as to minimize the time. There are no particular restrictions on the product removal position as long as it is a position where the consumer can easily remove the product from the storage box, but a position of 100 cm ± 30 cm from the floor is preferable.
The control unit adjusts the movement of the storage box to the product removal position in the shortest time possible.

<Operation section>

The mobile display and sales device 100 shown in Figures 3 and 4 is arranged without any unnecessary gaps in the space from the floor to the ceiling of a store, and has a plurality of movable storage boxes 101 attached at specified intervals, and stores and displays goods in the storage boxes 101 to sell the goods to consumers.
This mobile display and sales device 100 has a first sprocket 103, a second sprocket 104, an endless conveying body 102 wound around the first sprocket 103 and the second sprocket 104, and a plurality of storage boxes 101 attached to the endless conveying body 102 at predetermined intervals.

An annular endless chain 33 is stretched between a first sprocket 103 and a second sprocket 104, and is engaged with the endless conveying body 102 by a gear portion provided on the outer circumferential surface.
The first sprocket 103 is arranged in a pair at the top of the mobile display and sales device 100 (on the ceiling side of the store), and the second sprocket 104 is arranged in a pair at the bottom of the mobile display and sales device 100 (on the floor side of the store).
4, the second sprocket 104 rotates via the drive belt 124 by the operation of the motor serving as the power source 105, thereby rotating the endless conveyor 102 in the vertical direction to move the storage box 101 attached to the endless conveyor 102. The rotation direction of the endless conveyor 102 may be either clockwise or counterclockwise, and can be adjusted by switching the rotation direction of the motor serving as the power source 105.

An endless chain is used as the endless conveyor 102. As shown in FIG. 6, one end of a pin 121 in a chain unit 120 that constitutes the endless chain can be extended, and a storage box 101 can be attached to the extension of the pin 121. The storage box 101 is rotatably fixed to the extension with a nut 122.

The storage box 101 is made of plastic, and in this embodiment, polycarbonate resin is used.

The storage section 101b of the storage box can store a plurality of products. For example, in Fig. 5, three partitions 123 are provided in the horizontal direction of the storage box so that four products can be stored. The positions of the partitions 123 can be adjusted as appropriate.

The storage box 101 has a photoelectric sensor 113 as a product presence/absence sensor for detecting the presence or absence of each product in the storage box (see FIGS. 7 and 8).
When an empty storage box is found based on information from the photoelectric sensor 113, the control unit 107 moves the empty storage box to the product storage position and notifies a store clerk that products need to be stored in the box. This allows products to be quickly replenished in the empty storage box.
The product storage position is not particularly limited as long as it is a position where the store clerk can easily store the products in the storage box, but it is preferably a position of 100 cm±30 cm from the floor surface. In this embodiment, it is set to a position of 100 cm from the floor surface.
Methods for contacting the store clerk include, for example, a voice notification, a warning displayed on the cash register terminal screen, and a call to a mobile terminal.
The control unit 107 controls the motor serving as the power source 105 to adjust the time required for the storage box 101 to move to the product storage position to be as short as possible.

As shown in Figs. 9 and 10, the operation unit 106 has operation keys operated by the consumer and a display panel 106a that displays the product name, product details, etc. The operation unit 106 and the control unit 107 are electrically connected via a cable.

The control unit 107 may be, for example, a dedicated control board or MCU.
The control unit 107 calculates the sales amount of each product for a certain period based on information from the product removal sensor, and adjusts the display position of the storage box storing the high-selling product so that it is easily visible to consumers. This allows the high-selling product to be displayed in a position that is easily visible to consumers, i.e., in a position that is likely to catch the consumer's eye, which is expected to further increase sales.

As a product removal sensor, a combination of a sensor dog and a proximity sensor as shown in Figures 7 and 8 is used. This makes it possible to detect which product has been removed when multiple products are stored in a storage box, and to calculate the sales volume for a certain period of time.

In FIG. 7, sensor dog 1 (108), sensor dog 2 (109), sensor dog 3 (110), sensor dog 4 (111), and sensor dog N (112) are provided to correspond to the four stored products. Sensor dog 1 and sensor dog N are electrically connected to recognize product 1. Sensor dog 1 and sensor dog N are electrically connected to recognize product 1. Sensor dog 2 and sensor dog N are electrically connected to recognize product 2. Sensor dog 3 and sensor dog N are electrically connected to recognize product 3. Sensor dog 4 and sensor dog N are electrically connected to recognize product 4.

In other words, it is possible to detect which of product 1 to product 4 has been removed.
The number of items taken out of each product is counted for a certain period of time using an electrical signal, and the sales amount for the certain period of time can be calculated. In this embodiment, the certain period of time is one week, and the weekly sales amount is calculated.
The sales amount is the number of purchases of the product or the sales amount of the product, and is determined taking into consideration the number of products in stock. In other words, even if the sales amount of a product is high, if the product is out of stock, the product is not selected, and a process is performed to select the product with the next highest sales amount.

The position that is easily visible to consumers is a position that is easily noticeable to consumers, and is determined based on the position of the consumers' eyes, and differs depending on the type of store, the age group of consumers, etc., but for example, a position of 150 cm ± 30 cm from the floor is preferable. In this embodiment, the position is set to 150 cm from the floor.
In this embodiment, the storage boxes housing the first and second most popular weekly sales items are adjusted to be located on the left and right at a height of 150 cm from the floor.
As a method for adjusting the display positions of the storage boxes so that they are easily visible to consumers, when there is no replacement of products in the storage boxes, the control unit 107 can automatically adjust the positions.

The storage boxes 101 are marked with storage box numbers so that consumers can recognize them. In this embodiment, as shown in Fig. 3, a total of 16 storage boxes are attached, and the storage box numbers (1) to (16) are displayed on the attachment parts 101a.
As shown in Fig. 9, when the control unit 107 inputs the storage box number selected by the consumer into the operation unit 106, it performs a process of displaying the product name and product description stored in the storage box on the display panel 106a of the operation unit 106. This makes it easier for consumers to select products, which can contribute to increased sales. The product name and product description stored in the storage box are previously input by barcode reading or manual input by the operation unit 106 and stored in the recording unit.

As shown in Fig. 9, when a consumer inputs a storage box number into the operation unit 106 and presses the purchase button on the display panel 106a of the operation unit 106, the control unit 107 performs a process of moving the corresponding storage box to the product removal position. This allows the consumer to smoothly remove products, improving operability. If the consumer inputs a wrong number or wishes to cancel the purchase of a product, the reset button on the display panel 106a can be pressed to release the setting.
The product removal position is not particularly limited as long as it is a position where the store clerk can easily store the products in the storage box, but it is preferably a position of 100 cm±30 cm from the floor surface. In this embodiment, it is set to a position of 110 cm from the floor surface.
The control unit 107 controls the motor serving as the power source 105 to adjust the time required for the storage box 101 to move to the product removal position to be as short as possible.

In addition, in the first embodiment, multiple mobile display and sales devices can be arranged in parallel. This allows for more efficient use of the sales floor space in the store.
