[Detailed description of the invention]

[0001]

[Industrial application field] The present invention holds a plurality of boxed products such as cigarettes in an upright state in a storage case.
The present invention relates to a product advancing device in which the entire remaining portion is pushed forward when the product is taken out of the device at the time of sale.

[0002]

2. Description of the Related Art Heretofore, there have been various types of this type of product advancing device, for example, disclosed in Japanese Patent Publication No. 63-61007. As means for pushing the product, the product is usually pushed backward by using a compression spring, or the product is pulled back by using a tension spring, but in either case, a coil spring or a spiral spring is used. A leaf spring is used.

[0003]

According to the above-mentioned conventional product advancing device, a coil spring or a spiral leaf spring a is provided in a storage case b as shown in FIG.
There is a drawback that not only does the installation space for the springs become large and hinders, but also dead space is created. When the product is slid by the pressing force F, the pressing force is proportional to the weight W of the product (F = μW μ: friction coefficient). It is preferable that the pressure acts, that is, the pressing force changes in accordance with the number of remaining products, but in the case of a spiral leaf spring, the winding force is constant, so the pressing force does not change and the same force is applied to the last one. It is not suitable for pressing. This is not the case with ordinary coil springs, but a spring with a small winding diameter will be used to make the installation space of the spring as small as possible. There is a disadvantage that it is easy to set. Even if the number of turns is the same, if the winding diameter is increased, the maximum elongation dimension can be increased, but the installation space for the spring is increased, which is inconvenient. The present invention has been made to solve such a conventional problem, so that the spring does not obstruct and there is no dead space in the storage case, and the pressing force changes according to the number of products. An object of the present invention is to provide a product advance device.

[0004]

According to the present invention, as a means for technically solving this problem, a spring housing is provided between a case body that opens upward and a bottom surface of the case body that is dropped into the case body. A product receiving plate forming a portion, a spring stored in the spring storage portion, and a slider locked by the spring and pressing a product on the product receiving plate, wherein the spring is bent in a zigzag shape. The gist is that the leaf spring is formed.

[0005]

[Operation] A spring storage section is provided between the product receiving plate dropped and fixed in the case main body and the bottom of the case main body, and a leaf spring formed by being bent in a zigzag shape is mounted in this storage section. There is no obstruction and no dead space in the case.Even if the spring width is large, the height of the leaf spring does not increase, and the opening angle per pitch can be reduced to increase the maximum extension size. It becomes possible, and the spring force can be gradually reduced according to the number of products.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1, reference numeral 1 denotes a case body which opens upward, into which a product receiving plate 2 is dropped and fixed.
The spring housing 3 is formed between the case body 1 and the bottom surface.

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 as shown in FIG. A slit-shaped guide hole 2c is provided in the longitudinal direction, and the front end of the upper surface is formed as a cross-sectionally inclined surface 2d. or,
A pair of cuts 2e for locking the spring are provided at the lower end of the front hanging piece 2a, and a rising piece 2f is formed at the rear end of the upper surface.

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

The zigzag leaf spring 4 has a spring width D equal to or less than the product width, a height H of 4 to 5 mm, and a plate thickness of 0.2 to 0.5 mm.
The length L at the time of contraction is 5 mm or less, and the length L 'at the time of maximum extension is set within the elastic limit of the leaf spring. In this case, even if the spring width D is increased, the overall height of the leaf spring does not increase to H or more, and even if it is extended to the maximum, the opening angle θ per pitch may be small, and the pressing force is the amount of extension. Is proportional to Therefore, the length L 'at the time of extension of the leaf spring 4 can be set to 10 times or more of the length L at the time of contraction in a limited narrow space, and the width of the product is effectively used to use the plate material rather than the wire material. Therefore, even if the number of turns (the number of folds in the case of a plate material) is the same, the length at the time of contraction is shortened, and furthermore, it is most suitable as a pressing spring of an advance device such as preventing sagging of the spring.

Reference numeral 5 denotes a slider, which is an L-shaped product push plate 5a.
A horizontal stabilizer plate 5b for preventing rolling is attached to the product push plate 5a, and a cutout 5c for locking the spring is provided at the lower end of the front part of the product push plate 5a. The slider 5 is fitted and locked by fitting the rear end locking portion 4b of the leaf spring 4 into the cut 5c, and projects the vertical portion of the product pushing plate 5a upward from the guide hole 2c of the product receiving plate 2. Let it.

The device for unloading goods according to the present invention is constructed as described above, and pulls the slider 5 backward (to the right in the figure) against the leaf spring 4 as shown in FIG. A plurality of boxed products 6 are arranged on the product receiving plate 2 in an upright state, and are used by being pressed and held by the slider 5. In this case, since the leaf spring 4 is housed in the spring housing portion 3 below the product receiving plate 2, there is no obstruction, and the rear part in the case body 1 does not become a dead space, so that the number of stored products can be increased. Can be done. However, in the example shown in the drawing, the sample product 7 is used as a sample space, and the sample product 7 is stood and stored between the rising piece 2f at the rear of the product receiving plate 2 and the rear face plate 1b of the case body 1.

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

When the foremost product 6 'is taken out, the leaf spring 4 is contracted and the slider 5 is pulled forward, that is, the product 6 group is advanced by the product push plate 5a, and the product is brought to the top. The product 6 is again held in a forwardly inclined state by the inclined surface 2 d having a cross section of the product receiving plate 2. Therefore, it is very easy to take out the next product in the foreground.

In this way, the sliding operation is performed by the slider 5 sequentially. However, as described above, the leaf spring 4 is set so that its spring force is gradually reduced in accordance with the remaining number of the product 6, so that The advance operation is reliably performed without applying an excessively large pressing force. As described above, the length L when contracted to the maximum is less than the thickness of one product, so that even if the product is the last one, the advance is properly performed.

At the time of feeding, the slider 5 slides while the horizontal stabilizing plate 5b is in contact with the lower surface of the product receiving plate 2, so that the slider 5 is prevented from rolling and the vertical portion of the product pushing plate 5a is received. The plate 2 can be smoothly moved along the guide hole 2c.

FIG. 3 shows an embodiment in which a plurality of advance devices according to the present invention are arranged in a row, and a storage case 1 'having a predetermined size.
Is divided into a plurality of sections by a partition plate 8, and a member of the advance device is incorporated in each section.
In this case, since various kinds of products can be stored separately, it is very convenient in the case of cigarette sales with many brands.

[0017] The advance device according to the present invention can be widely applied not only to cigarettes but also to other products. Further, the zigzag plate spring can be used not only as a tension spring but also as a compression spring. However, when the spring is compressed, it may bulge outward and rub against the inner wall of the spring accommodating portion to cause extra friction. Therefore, the tension spring is safer.

[0018]

[Effects of the Invention] As described above, according to the present invention,
A spring storage part was provided between the product receiving plate dropped and fixed in the case body and the bottom of the case body, and a leaf spring formed by zigzag bending was attached to this spring storage part, so that the spring was completely in the way. In addition, since no dead space occurs in the case, the inside of the case body can be effectively used. The use of zigzag leaf springs does not increase the leaf spring height even if the spring width is increased, making it possible to increase the maximum extension size by reducing the opening angle per pitch. And excellent effects such as being able to gradually change the spring force according to the number of products.
