Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a product unloading device for an automatic vending machine which sells products in paper packs, cans, bottles or PET bottles.

[0002]

2. Description of the Related Art Conventionally, as this type of product unloading device,
For example, as described in Japanese Unexamined Patent Publication No. 5-108941, a plurality of product storage units that stack and store products in the vertical direction, and a vertically elongated hollow partition member that partitions each product storage unit in the width direction, There is known one provided with a carry-out unit attached to the lower end side of the partition member.

The carry-out unit includes a rotatable opening / closing plate for opening and closing the lower surface of the product storage portion, a substantially semicircular rotation restricting plate for restricting downward rotation of the opening / closing plate at a substantially horizontal position, and a product storage unit. The product holding plate is provided so as to be capable of projecting and retracting in the width direction, and a cam-shaped contact member that abuts on a predetermined portion of the product holding plate to project the product holding plate into the product storage part. In this carry-out unit, when an arbitrary product is selected, the product holding plate is projected into the product storage unit and locked to the second product from the lower side of the product storage unit to hold the second product from the lower side. By holding the plate in the product storage section and releasing the rotation restriction of the opening / closing plate by the rotation restriction plate in this state, the opening / closing plate is rotated downward by the weight of the lowest product, and the lowest product is It is designed to be dropped out of the product storage section.

Further, as shown in FIG. 13, the partition member 1 is attached to a storage plate 2 having a U-shaped cross section, and its lower end side is formed shorter than the back plate 2. That is, the lower end side of each product storage unit 3 is partitioned by the carry-out unit 4 attached to the lower end of the partition member 1.

[0005]

By the way, side plates 4b are attached to the carry-out unit 4 to cover both side surfaces of the unit body 4a in the width direction, and each side plate 4b forms a partition surface in the product storage unit 3. There is. In this case, as shown in FIG. 14, the carry-out unit 4 has its upper end inserted into the partition member 1 so as to be attached, so that a step is formed between the side surface of the partition member 1 and the side plate 4b. There is a risk of defective protrusion.

The width T of the partition member 1 includes a plate thickness T1 of each side surface of the partition member 1, a width T2 of the unit body 4a of the carry-out unit 4 and a plate thickness T3 of each side plate 4b. Become. For this reason, the width dimension T of the partition member 1 becomes large, and there is a problem that the entire device becomes large in the width direction.

Further, in the above-mentioned product unloading device, the opening / closing plate is biased by a spring so as to rotate to a predetermined position above the rotation restricting position by the rotation restricting plate, and the opening / closing plate is rotated to the upper position. Some of them are designed to detect when a product is sold out in tandem with the movement. That is, when there is a product in the product storage unit, the open / close plate does not rotate upward due to the weight of the product, but when the product in the product storage unit is sold out, the open / close plate rotates to the upper position by the spring and interlocks with this. The sold-out detection switch detects that the product is sold out.

However, in the above structure, since the opening / closing plate is biased upward by the spring, when the product is carried out, the carried-out product is always rotated by the spring biasing force against the weight of the product. Therefore, in the case of a small and light product, there is a problem that the opening and closing operation of the opening and closing plate becomes slow and, in some cases, a delivery failure occurs.

Further, the product holding plate is designed to project into the product storage portion by the contact of the abutting member. However, since the projecting amount is constant, the projecting amount is always appropriate according to the external dimensions of the product. Therefore, there is a possibility that a delivery failure may occur due to an inappropriate protrusion amount.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a product unloading device capable of reliably preventing a product unloading defect.

[0011]

In order to achieve the above object, the present invention provides a plurality of product storage units for stacking and storing products in a vertical direction and a space between each product storage unit in the width direction. A hollow partition member for partitioning, and a carry-out unit attached to the lower end side of the partition member, wherein the lower surface of the product storage unit is opened while the second product is held from below the product storage unit by the carry-out unit. Thus, in the product unloading device in which the lowest product is dropped from the product storage unit, the unit body of the unloading unit is formed so that both side surfaces in the width direction are opened, and the unloading unit is provided in the partition member. The unit body is inserted and attached so that both side surfaces are covered by the side surfaces of the partition member.

With this configuration, since both side surfaces of the unit body are covered by the side surfaces of the partition member, no step is formed on the partition surface on the side of the unloading unit in the product storage section. Further, since it is not necessary to separately attach a side plate to the unit body, the width dimension of the partition member is a dimension obtained by combining the plate thickness of the side surface of the partition member and the width dimension of the unit body.

Further, according to a second aspect of the present invention, a product storage unit for stacking and storing products in a vertical direction and an opening / closing unit that is attached to the lower end side of the product storage unit in a vertically rotatable manner to open and close the lower surface of the product storage unit. A plate, a rotation restricting member that restricts downward rotation of the opening / closing plate at a predetermined position, and a product holding member that appears in the product storage portion in the width direction, and the product holding member projects into the product storage part. The second product from the lower side is held in the product storage unit by being locked to the second product from the lower side of the product storage unit, and in this state, the downward rotation restriction of the opening / closing plate by the rotation restriction member is released. Thus, in the product unloading device in which the opening / closing plate is rotated downward to drop the lowest product from the product storage unit, the opening / closing plate is located at a predetermined position above the rotation restricting position by the rotation restricting member. First bias to rotate to A step, a sold-out detection unit that detects the sold-out of the product in conjunction with the rotation of the opening / closing plate to the upper predetermined position, and the downward rotation is restricted by the rotation restriction member. When the rotation restriction is released, the auxiliary member is locked to the opening / closing plate and rotates downward together with the opening / closing plate, and the second urging means for urging the auxiliary member downward.

As a result, when the products in the product storage section are exhausted, the opening / closing plate is rotated upward by the first urging means,
The sold-out detection means, which is linked to this, detects the sold-out of the product. In addition, since the opening / closing plate rotates downward together with the auxiliary member by the urging force of the second urging means when the product is unloaded, the lower surface of the product storage unit is forcedly rotated by the opening / closing plate not only by the weight of the product. Is released.

Further, in claim 3, a product storage portion for stacking and storing the products in a vertical direction, an opening / closing plate for opening and closing a lower surface of the product storage portion, and a product provided in the product storage portion so as to be retractable in the width direction. A holding member and an abutting member that abuts on a predetermined portion of the product holding member to cause the product holding member to project into the product storage unit, and the product holding member projects into the product storage unit from below the product storage unit. The second product from the bottom is held in the product storage unit by being locked to the second product, and in this state, the opening / closing plate is rotated downward to drop the lowest product from the product storage unit. In the carry-out device, by changing the contact position of the contact member with the product holding member, the amount of protrusion of the product holding member into the product storage unit is arbitrarily adjustable.

Thus, by appropriately adjusting the amount of protrusion of the product holding member into the product storage portion, it is possible to obtain an appropriate amount of protrusion according to the external dimensions of the product.

According to a fourth aspect of the present invention, in the article carrying-out device according to the third aspect, the contact member is provided with a plurality of contact portions corresponding to contact positions with the commodity holding member, and each contact portion serves as the commodity holding member. It is formed by an inclined surface that makes surface contact, and the inclination angle of some contact portions is different from the inclination angle of other contact portions.

Thus, in addition to the effect of the third aspect, since the projecting amount of the product holding plate becomes a projecting amount according to the inclination angle of each contact part, the projecting amount of the product holding plate by each contact part is always accurate. Can be In this case, since the product holding plate and the inclined surfaces of the respective contact portions are in surface contact with each other, wear of the parts due to local contact does not occur.

After that, when the rotation of the rotation restricting plate 24 progresses, the rotation restricting of the opening / closing plate 22 and the auxiliary plate 25 by the rotation restricting plate 24 is released. As a result, as shown in FIG. 12, the auxiliary plate 25 is rotated downward by the second spring 26, and the locking piece 25a of the auxiliary plate 25 is locked to the locking piece 22b of the opening / closing plate 22 to open / close the opening / closing plate. 22 rotates downward together with the auxiliary plate 25, the lower surface of the product storage unit 10 is opened, and the lowest product A is dropped and carried out.

Further, in the above-mentioned product unloading device, when it is desired to adjust the position of the product holding plate 23, for example, when the product is changed to one having a different external dimension, the slide plate 23b is used.
The product holding plate 23 is vertically moved to an arbitrary position by the operation pin 23c. At this time, by aligning the product holding plate 23 with an arbitrary concave portion 29a of the contact member 29, it is possible to set the protrusion amount of the product holding plate 23 according to the inclination angle of the inclined surface 29b.

As described above, according to the product unloading apparatus of this embodiment, the unit main body 21 is formed so that both side surfaces thereof are open, and both side surfaces of the unit main body 21 are covered by the side surfaces of the partition member 11. Therefore, a step is not generated on the side of the carry-out unit 20 in the product storage unit 10, and a carry-out defect due to the step can be reliably prevented. In this case, since it is not necessary to separately attach a side plate to the unit main body 21, the width dimension of the partition member 11 can be reduced accordingly, and the entire device can be downsized in the width direction.

When the product A in the product storage unit 10 is exhausted, the opening / closing plate 21 is rotated upward by the first spring 26, and the sold-out detection mechanism 30 which is linked with the opening / closing plate 21 detects the sold-out of the product. In the above configuration, by providing the auxiliary plate 25 that rotates the opening / closing plate 21 downward by the urging force of the second spring 27 when the product is unloaded, the opening / closing plate 21 is forcedly rotated regardless of only the weight of the product A. Since the lower surface of the product storage unit 10 is opened by the movement, the product A can be quickly and reliably carried out without being affected by the first spring 26, and the carry-out failure is surely achieved even for a lightweight product. Can be prevented.

Furthermore, by changing the contact position of the contact member 29 with the product holding plate 23 in the vertical direction, the product storage unit 1
Since the protruding amount of the product holding plate 23 into 0 can be adjusted arbitrarily, the product holding plate 23 can always have an appropriate protruding amount according to the outer dimensions of the product, and It is possible to reliably prevent defective delivery.

In this case, the product holding plate 23 is attached to the product storage unit 1.
A plurality of inclined surfaces 29b that come into contact with the product holding plate 23 are provided on the abutting member 29 that projects into the 0.
Is formed so as to be different from the inclination angles of the other inclined surfaces, and the projecting amount of the product holding plate 23 is set to the projecting amount according to the tilt angle of the inclined surface 29b.
The amount of protrusion of the product holding plate 23 can always be made accurate, and the reliability can be improved.

Further, since the product holding plate 23 and the inclined surface 29b are brought into surface contact with each other, abrasion due to local contact does not occur, and the life of parts can be maintained for a long period of time.

[0041]

As described above, according to the article unloading device of the first aspect, a step does not occur on the partition surface on the unloading unit side in the article storage section, so that the unloading failure due to the step is reliably prevented. be able to. In this case, since it is not necessary to separately attach a side plate to the unit main body, the width dimension of the partition member can be reduced accordingly, and the entire device can be downsized in the width direction.

Further, according to the article discharge device of claim 2,
Even when the product is sold out by interlocking with the upward rotation of the opening / closing plate by urging the opening / closing plate upwards, the forced rotation of the opening / closing plate does not depend only on the weight of the product. Since the lower surface of the product storage unit can be opened by the movement, the product can be quickly and reliably carried out without being affected by the upward biasing force of the opening / closing plate. It can be surely prevented.

According to the article unloading device of claim 3,
Since the product holding plate can always have an appropriate protrusion amount according to the external dimensions of the product, it is possible to reliably prevent a delivery failure due to an inappropriate protrusion amount.

According to the article unloading device of claim 4,
In addition to the effect of claim 3, the amount of protrusion of the product holding plate can always be made accurate, so that the reliability can be improved and wear due to local contact between the product holding member and the contact member. Since it does not occur, the life of the component can be maintained for a long time.
