The present invention relates to a hanging display tool with a weighing function and an article management system capable of measuring suspended and displayed articles.

In recent years, at retail stores such as supermarkets and convenience stores, attention has been focused on the opening of unmanned stores, and research and development of related technologies is progressing. Especially in unmanned stores, it is necessary to accurately grasp the items taken out by customers and their numbers in order to make payments. In addition, in order to replenish and display the goods, it was necessary to accurately grasp the inventory status of the goods. Therefore, in order to accurately manage the inventory of goods, a display tool capable of measuring the displayed goods has been proposed (see Patent Document 1). The display tool shown in Patent Document 1 locks a hole or a hook formed in an article (single article or a packaging bag containing the article) in a rod-shaped hanging arm portion of a hanging display tool attached to a display fixture. It is a hanging display that hangs an article by giving it a measurable function.

The hanging display tool with a weighing function of Patent Document 1 is configured by attaching a hanging arm portion capable of holding an article in a suspended state to the front surface of a load cell whose rear surface is bolted to a display fixture. The load cell can measure the amount of deformation of a metal strain-causing body caused by strain as a change in resistance value with a strain gauge attached to the strain-causing body, and is an article suspended from a hanging arm and displayed. Can be weighed. According to this, the number of articles taken out can be calculated from the change in the total weight of the articles suspended and displayed on the hanging arm portion based on the resistance value recorded in advance.

The load cell 4 is a shear-sensitive so-called beam-type load cell, and is mainly composed of a rod-shaped strain-causing body 11 and a strain gauge 15 attached to the strain-causing body 11. The wiring connected from the load cell 4 and the detection unit connected to the wiring are not shown. The load cell 4 is arranged so that the longitudinal direction of the strain generating body 11 is along the front-rear direction of the hanging display tool 1, that is, the extending direction of the hanging arm portion 6, and the load cell 4 is arranged substantially at the center of the strain generating body 11 in the longitudinal direction. A through hole 11a penetrating in the left-right direction is formed, and the upper portion and the lower portion of the through hole 11a are fragile portions that are easily deformed, and a strain gauge 15 is attached to the fragile portion.

In the upper plate portion 9a of the rod member 9 of the holding member 2, two holes 16 penetrating in the thickness direction are formed side by side in the longitudinal direction on the rear side (one end side in the longitudinal direction). The strain generating body 11 of the load cell 4 is formed with two screw holes 17 penetrating in the thickness direction arranged side by side in the longitudinal direction on the rear side (one end side in the longitudinal direction). Bolts 19 are inserted from above the two holes 16 formed in the rod member 9 of the holding member 2 and screwed into the two screw holes 17 formed in the strain generating body 11 of the load cell 4, so that the holding member 2 is formed. It is fixed to the upper surface 11b of the strain generating body 11. Further, an annular spacer 20 through which the bolt 19 is inserted is arranged between the rod member 9 and the strain generating body 11, and the rod member 9 and the strain generating body 11 are separated from each other at a predetermined interval.

The base member 8 of the base member 3 is formed with two holes 18 penetrating in the thickness direction on the front side (the other end side in the longitudinal direction) side by side in the longitudinal direction, and the locking portion 7 of the base member 3 is formed. A hole 23 penetrating in the thickness direction is formed in the hole 23, a bolt 19 is inserted into the hole 18 from below, a bolt 21 is inserted into the holes 23 and 18 from below, and the front side of the strain generating body 11 of the load cell 4 ( The base member 3 is fixed to the lower surface 11c of the strain generating body 11 by being screwed into two screw holes 17 formed on the other end side in the longitudinal direction. Further, an annular spacer 20 through which bolts 19 and 21 are inserted is arranged between the base member 8 and the strain generating body 11, and the base member 8 and the strain generating body 11 are separated from each other at predetermined intervals. Further, a screw hole 7c penetrating in the front-rear direction is formed in the rear plate portion 7b of the locking portion 7, and a knob screw 22 is screwed.

Specifically, as shown in FIG. 3, the locking portion 7 is fixed to the front side of the base member 8 of the base member 3 and overlaps with one of the holes 18 formed in the base member 8 on the front side. A hole 23 is formed in the hole 23 so that the bolt 21 can be inserted through the hole 23. Therefore, the locking portion 7 of the base member 3 is provided below the front side of the load cell 4 which is vertically overlapped with the front side of the base member 8 in the longitudinal direction. Further, the hole 23 is counterbored so that the head 21a of the bolt 21 does not project inside the downward U-shaped locking portion 7.

The strain gauge 15 of the load cell 4 is communicably connected to a management device (calculation means, see FIG. 1) 50 capable of performing calculations such as a computer.

Since the hanging display tool 1 has the above-described configuration, when the article A is suspended from the hanging arm portion 6 of the holding member 2, the strain-causing body 11 is distorted around the fragile portion by the load of the article A. It will be. The load cell 4 can output the amount of deformation of the strain-causing body caused by this strain as a change in resistance value by the attached strain gauge 15. A communication unit (not shown) provided for each load cell 4 transmits resistance value information to the management device 50. In the management device 50, the weight is calculated from the resistance value measured by the strain gauge 15, and the weight can be measured as the number of articles A suspended from the hanging arm portion 6 and displayed.

In the management device 50, identification information is given to each hanging display tool 1, and for each identification information, the type of the displayed article A, the number displayed, and the resistance value due to the increase or decrease of the article A The load corresponding to the change in the above is managed in association with the reference information obtained in advance. Since the weight of each item is different depending on the type of the article A, the change in the resistance value due to the increase or decrease of the article A is also different.

The management device 50 can calculate the change in the total load of the article A suspended and displayed on the hanging arm portion 6 as the number of the articles A taken out while using the reference information associated with the identification information. can.

The information on the type of the item A taken out and the number thereof grasped in this way can be used for the settlement at the unmanned store. In addition, the clerk can grasp which article A should be replenished to which hanging display tool 1 at the time of the replenishment display of the article A.

Since the hanging arm portion 6 is formed so as to extend in the depth direction of the display fixture 10, the force point moves back and forth depending on whether the article A is suspended on the tip side or the root side thereof. There is a difference in the force applied to the strain generating body 11 of the load cell 4 which is located on the side and serves as the point of action. Therefore, as the management device 50, with respect to the identification information of the hanging display tool 1, two articles A are taken out from the state where the resistance value changes due to the increase / decrease from the total number of displays (for example, the total number of displays is 10). It is preferable that the reference information includes the change in the resistance value in the case of the above case and the change in the resistance value when one article A is taken out from the state where the total number of displays is 3. As shown in FIG. 3, since the hanging arm portion 6 is attached so as to be inclined so as to gradually face upward toward the tip, the article A suspended on the root side is always collected, so that the reference information is used. The error of the standard of the change of the resistance value due to the increase or decrease from the total number of displays included is small.
