Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a direct-loading type product dispensing device for directly stacking and storing products.

2. Description of the Related Art This type of product dispensing apparatus is configured as shown in Japanese Patent Application Laid-Open No. 62-134787. 3 to 7 show the configuration.

As shown in FIG. 3 (a), the first and second flappers 1a and 1b are pivotally supported at one end so as to be pivotable downward, and the pivot shafts 2a and 2b are disposed inside each other. First and second
Of the first and second flappers 1a, 1 with a semi-circular cam plate 3 pivotally supported for horizontal rotation below the flappers 1a, 1b of
It is configured to support b. The first and second flappers 1a and 1b are the stockers 5a and 5 of the first and second columns 4a and 4b.
The products I1, I2, I3, ... Of the first column 4a are stacked on the first flapper 1a. Items on the second column 4b above the second flapper 1b
II1, II2, II3 ... are stacked. As shown in FIG. 3 (b) showing a view taken along the line AA 'in FIG. 3 (a), the cam plate 3
Is at a 0 ° position, and downward rotation of the first and second flappers 1a and 1b is restricted. As shown in FIGS. 4 (a) and 4 (b), when the support shaft 6 of the cam plate 3 is rotated 90 ° in the direction of arrow B, the engagement between the first flapper 1a and the cam plate 3 is released and the first flapper 1a is disengaged. The flapper 1a rotates downward. At this time, the cam body 7 attached to the support shaft 6 before the first flapper 1a and the cam plate 3 are disengaged from each other is the first stopper 8a.
And push the tip of the first stopper 8a to the products I1 and I2.
It is configured so as to project between the products, and when the first flapper 1a is opened as shown in FIG. 4, the product I2 and the products I3, I4 ... Above this are supported by the first stopper 8a. ing. Therefore, only the bottommost product I1 is paid out.

When the payout of the product I1 is completed, the cam plate 3 rotates from the 90 ° position to the 180 ° position as shown in FIGS. 5 (a) and 5 (b), and the first and second flappers 1a and 1b. The first flapper that was released by reengaging the cam plate 3 with both
1a returns to the horizontal position as shown in FIG. 5 (a). Further, before the cam plate 3 rotates to reach the 180 ° position, the pushing out of the first stopper 8a by the cam body 7 is released, and as shown in FIG. 6 (a), the product I2 and the product I3 above are sold. , I
4 drop by a distance L1 and are supported by the first flapper 1a.

The same applies to the delivery of products on the side of the second stocker 4b when the cam plate 3 rotates from the 180 ° position to the 360 ° position. FIG. 7 shows the movement of the first and second flappers 1a and 1b when the cam plate 3 is rotated from the 0 ° position to the 360 ° position and the lowering of the product by the first and second stoppers 8a and 8b. Show the situation.

SUMMARY OF THE INVENTION In such a conventional configuration, the first and second stoppers are provided.
When the fall regulation of the products by 8a, 8b is lifted, the first and second flappers 1a, 1b are in the horizontal position and the distance L
Since only one product falls, product I2 is subject to the impact load that accompanies the fall of product I3 and all products above it, and product II2 is also subjected to a large impact load, resulting in product I2, II
2 etc. may be damaged.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a direct-loading type product dispensing apparatus capable of reducing an impact load applied to a product.

Means for Solving the Problems A direct-loading type product dispensing device of the present invention rotates the flapper past a horizontal position to an upper position before releasing the state in which the second descending product from the bottom is restricted from being lowered. Lifting means for moving the flapper to maintain the flapper in the upper position and posture when the second product from the bottom is lowered is provided.

With this configuration, when the descent restriction of the product is released, the flapper is rotated upward by the lifting means from the horizontal position, and the fall distance of the product when the descent restriction is released is above the horizontal position. The distance becomes shorter by the distance turned.

Embodiment Hereinafter, an embodiment of the present invention will be described with reference to FIG. 1 and FIG. Note that components having the same functions as those in FIG. 3 showing a conventional example are denoted by the same reference numerals and described.

FIG. 1 (a) shows the product dispensing device of the present invention, in which only the first column 4a of the first and second columns 4a, 4b has the projection 9 as the lifting means and the first flapper.
It is provided on the back surface of 1a.

The shape of the projection 9 will be described based on the operation. FIGS. 1 (a) and 1 (b) show a state where the cam plate 3 is rotated to the 180 ° position. The projection 9 contacts the cam plate 3 while the first flapper 1a is rotated from the open position to the 180 ° position when the cam plate 3 is at the 90 ° position and the first flapper 1a is moved in the virtual line. After being lifted to the horizontal position as shown by, the height is gradually increased so that the first flapper 1a is lifted to the solid line position. The push-out of the stopper 8a is released, and the product I2 and the product I3 ... Above which the drop regulation is released fall on the first flapper 1a. When the cam plate 3 is rotated again toward the 90 ° position through the 270 ° position, 360 ° position and 0 ° position, the height of the projection 9 abutting on the cam plate 3 is gradually lowered to 90 °. In the position, the first flapper 1a gradually returns to the horizontal position.

Thus, when the descent restriction of the product is released, the product I2 and the product I3 ... Above it fall only the distance L2 as shown in FIG. The impact load acting on the product I2 is reduced by the amount shorter than L1.

FIG. 2 shows not only the back side of the first flapper 1a but also the second side.
The movement of the first and second flappers 1a and 1b when the same protrusion 9 is provided on the back surface of the flapper 1b and the state of the descent control of the product by the first and second stoppers 8a and 8b are shown.

EFFECTS OF THE INVENTION As described above, according to the present invention, prior to the release of the state in which the descent of the second product from the bottom is regulated, the flapper is swung to the upper position by passing the horizontal position, and then the flapper is moved to the upper position. Since the lifting means for maintaining the flapper in the upper position posture is provided when the second product descends, the drop distance becomes shorter than before by the distance lifted by this lifting means, and the impact load acting on the product is weakened. The product can be protected from damage accidents.
