[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a product advancing device for holding a plurality of boxed products such as cigarettes in an upright state in a storage case side by side and holding the plurality of products side by side so that when the product is taken out of the front one, the rest is pushed forward. Is.

[0002]

[Prior art]

 Conventionally, there are various forms of this type of product advancing device, which are disclosed in, for example, Japanese Patent Publication No. 63-61007. As a means for pushing the product, usually, a compression spring is used to push the product afterward, or a tension spring is used to pull the product back to the front.In either case, a coil spring or a spiral shape is used. The leaf spring of is used.

[0003]

[Problems to be solved by the device]

 According to the conventional product advancing device described above, as shown in FIG. 4, since the coil spring or the spiral leaf spring a is provided in the storage case b, the space for installing the spring becomes large and becomes an obstacle. There is a drawback that a dead space is generated accordingly. Also, when a product is slid by a pressing force F, it is proportional to the weight W of the product (F = μW μ: coefficient of friction), so a large pressing force is applied when there are many products, and a small pressing force when there are few products. It is preferable that the pressing force acts, that is, the pressing force changes according to the number of remaining products, but in the spiral leaf spring, the winding torque is constant, so the pressing force does not change and the same is applied to the last one. It is not suitable for pressing with force. This is not the case with ordinary coil springs, but in order to make the spring installation space as small as possible, a spring with a small winding diameter will be used. It has a drawback that it is easily worn out. Even if the number of turns is the same, increasing the winding diameter can increase the maximum extension dimension, but this is inconvenient because the spring installation space becomes large. The present invention has been made in order to solve such a conventional problem, and the spring does not interfere with the occurrence of a dead space in the storage case, so that the pressing force can be appropriately changed depending on the number of products. The challenge was to provide a product advance device.

[0004]

[Means for Solving the Problems]

 As a means for technically solving this problem, the present invention provides a case main body that opens upward and a product receiving plate that is dropped into the case main body to form a spring accommodating portion between the bottom of the case main body. A leaf spring formed by zigzag-folding the spring housed in the spring housing and a slider that is locked by the spring and pushes the product on the product receiving plate. Is the gist.

[0005]

[Work]

 A spring storage section is provided between the product receiving plate that is dropped into the case body and fixed, and the bottom surface of the case body, and a leaf spring formed by bending in a zigzag shape is installed in this storage section. The dead space does not occur in the case, the height of the leaf spring does not increase even if the spring width is large, and the opening angle per pitch can be reduced to increase the maximum extension dimension. Moreover, the spring force can be gradually changed to a small value according to the number of products.

【Example】

 In FIG. 1, reference numeral 1 denotes a case body having an upward opening, and a commodity receiving plate 2 is dropped into the case body and fixed therein, and a spring accommodating portion 3 is formed between the case body 1 and a bottom surface thereof.

The product receiving plate 2 has substantially the same width as the inner width of the case body 1, and has hanging pieces 2a and 2b formed at the front and rear ends thereof, respectively, as shown in FIG. A slit-shaped guide hole 2c is provided in the longitudinal direction, and the front end portion of the upper surface is formed into an inclined surface 2d having a cross-section. Further, a pair of cutouts 2e for spring engagement are provided at the lower end portion of the front hanging piece 2a, and a rising piece 2f is formed at the rear end portion of the upper surface.

Reference numeral 4 is a leaf spring formed by bending in a zigzag shape, and a substantially U-shaped locking portion 4a is formed at the tip portion thereof, and a locking portion 4b is also formed at the rear end portion thereof. The locking portion 4a is housed in the spring housing portion 3 by being fitted and locked in the notch 2e of the front hanging piece 2a of the product receiving plate 2.

The zigzag plate spring 4 has a spring width D of not more than the product width, a height H of 4 to 5 mm, a plate thickness of 0.2 to 0.5 mm, and a length L when contracted of one product. The thickness L'at the maximum extension is set within the elastic limit of the leaf spring. In this case, even if the spring width D is increased, the height of the entire leaf spring does not increase above H, and even if it is extended to the maximum, the opening angle θ per pitch is small, and the pressing force is the extension amount. In comparison with. Therefore, the length L'when the leaf spring 4 is extended can be set to 10 times or more the length L when it is contracted in a limited narrow space, and the plate material is used rather than the wire rod by effectively utilizing the product width. Therefore, even when the number of turns is the same (the number of folds in the case of a plate material), the length when contracted is shortened, and moreover, it is optimal as a pressing spring for the advance device because it prevents the spring from settling.

Reference numeral 5 denotes a slider, which is formed by attaching a horizontal stabilizer plate 5b for preventing lateral movement to an L-shaped product pushing plate 5a, and a notch for spring locking at a lower end of a front portion of the product pushing plate 5a. 5 c is provided. In this slider 5, the rear end locking portion 4b of the leaf spring 4 is fitted and locked in the notch 5c, and the vertical portion of the product pressing plate 5a is moved upward from the guide hole 2c of the product receiving plate 2. Make it protrude.

The product advancing device according to the present invention is configured as described above, and as shown in FIG. 1, pulls the slider 5 backwards (to the right in the drawing) against the leaf spring 4 to remove a cigarette or the like. A plurality of boxed products 6 are arranged on the product receiving plate 2 in an upright state, and are pressed and held by the slider 5 for use. In this case, since the leaf spring 4 is stored in the spring storage portion 3 below the product receiving plate 2, there is no obstruction and the rear portion of the case body 1 does not become a dead space, so the number of products to be stored is increased. It can be done. However, in the illustrated example, the sample product 7 is used as a sample space, and the sample product 7 is stood up and stored between the rising piece 2f at the rear part of the product receiving plate 2 and the rear surface plate 1b of the case body 1.

The frontmost product 6 ′ is pushed up by the inclined surface 2 d having a cross section of the product receiving plate 2 to the forward tilted state, so that it can be easily grasped and easily taken out.

When the frontmost product 6 ′ is taken out, the leaf spring 4 contracts to draw the slider 5 forward, that is, the product pushing plate 5 a causes the product 6 group to be forwarded, and becomes the head. The merchandise 6 is held forward by the inclined surface 2d having a cross section of the merchandise receiving plate 2. Therefore, it becomes very easy to take out the next frontmost product.

In this way, the forward movement is sequentially performed by the slider 5, but as described above, since the spring force of the leaf spring 4 is set to gradually weaken according to the remaining number of the products 6, The forward movement can be reliably performed without applying an excessively large pressing force. Since the length L when contracted to the maximum is not more than the thickness of one product as described above, even if the product becomes the last one, the advance is properly performed.

At the time of the forward movement, the slider 5 slides while the horizontal stabilizer 5b is in contact with the lower surface of the product receiving plate 2 to prevent lateral rolling, and to prevent the vertical portion of the product pressing plate 5a from receiving the product. The plate 2 can be smoothly moved along the guide hole 2c.

FIG. 3 shows an embodiment in which a plurality of the advance devices of the present invention are arranged side by side. A storage case 1 ′ having a predetermined size is divided into a plurality of compartments by a partition plate 8 and each compartment is divided into a plurality of compartments. It is configured to incorporate the members of the dispensing device. In this case, various commodities can be stored separately, which is very convenient when selling cigarettes with many brands.

The advance device according to the present invention can be widely applied to not only tobacco but also other products. Further, the zigzag leaf spring can be used not only as a tension spring but also as a compression spring, but when the spring is compressed, it may bulge outward and rub against the inner wall of the spring accommodating portion, causing extra friction. Because of this, tension springs are safer.

[0018]

[Effect of device]

 As described above, according to the present invention, the spring accommodating portion is provided between the commodity receiving plate fixed by dropping it in the case body and the bottom surface of the case body, and is formed by bending the spring accommodating portion in a zigzag shape. Since the leaf springs are installed, the springs do not interfere at all and there is no dead space inside the case, so the inside of the case can be used effectively. Also, since the zigzag leaf spring is used, the height of the leaf spring does not increase even if the spring width is increased, and it is possible to reduce the opening angle per pitch and increase the maximum extension dimension. In addition, there is an excellent effect that the spring force can be gradually changed according to the number of products.
