Abstract

PURPOSE:To reduce the driving force of a driving part by pushing out only a sales product so as to sell it. CONSTITUTION:Commodity holding plates 9A and 9B hold the next product by permitting the commodity holding plates 9A and 9B which are appear/ disappear in a commodity passage to appear/disappear by cams 10A and 10B provided for the driving part. Then, a supporting stand 2 loading the sales commodity 3 is moved in a lower direction by the operation of the other cam provided for a driving shaft. Thus, the next commodity and the sales commodity 3 are detached and therefore the sticking of the commodities owing to freezing is removed by the dead weight of the sales commodity 3. Furthermore, the load of the upper commodity added to the sales commodity 3 is also removed. Consequently, the driving force of the driving part discharging the sales commodity 3 can be reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a vending machine, and particularly to a vending device suitable for selling heavy products with weak containers.

(B) Conventional technology There is a vending device that stacks up products and sells the lowest products one by one by using the reciprocating motion of a drive unit to push out the products one by one (1986- 74179
Publication No.). In addition, there is a sales device that operates a delivery board on which the next sale product is placed while blocking the next sale product, and drops and discharges the sale product one by one (Special Publication No. 54-3375
Publication No. 9).

(c) Problems to be Solved by the Invention However, in the case of the former type of vending device, the weight of the vending products is relatively light, and the atmospheric conditions of the product storage section are either normal temperature or refrigerated.
It is useful for things that are limited to things like hot storage.

Therefore, if the atmospheric conditions in the product storage section are frozen, the products may freeze and stick together, making it necessary to peel them off and sell them during the selling operation, which increases the thrust of the selling device. , a problem arises in that the container may be damaged due to the peeling off.

In addition, in the case of the latter type of vending device, the sold products fall directly into the sales aisle and are discharged through the outlet, so especially in the case of heavy products, the container may be deformed due to the impact of the fall.
There is a problem with damage.

The present invention has been made in view of the above-mentioned problems, and is a vending machine that enables the vending device to operate reliably without problems under the conditions that the product weight is large and the container form is weak against drop impact. The purpose is to provide sales equipment for

(d) Means for Solving the Problems In order to solve the above-mentioned problems, the present invention has a product holding plate that can freely move into and out of the product storage aisle to hold the next product for sale.
A cam that controls the appearance and retraction of the product holding plate is used to hold the product holding plate, and a support base on which the product to be sold is placed is movable in the product loading direction. It is configured to operate in the loading direction.

In addition, if the vending machine is left open on the sales aisle side, and the entire vending machine is shaken due to mischief, etc.
Since there is a possibility that the product may be ejected, a restraining member pivotally supported by the cam is provided so as to be retractable from the sales passage side.

(e) Operation A product holding plate that can freely appear and retract into the product passage is moved in and out using a cam provided in the drive unit, so that the product holding plate holds the next sale product and also supports the support stand on which the sales product is placed. By moving the next product downwards using another cam action installed on the drive shaft, the next product and the product to be sold are separated, and the weight of the product to be sold releases the frozen adhesion of the products, and the product is separated from the product to be sold. Since the load applied to the upper product is also released, the thrust of the drive unit for dispensing the sales product can be reduced. In addition, damage to products due to freeze lock is eliminated.

(f) Example Embodiments of the present invention will be described below based on the drawings.

FIG. 1 is a front view of the vending apparatus showing the sales period state. To explain according to the figure, products 3 are loaded on a support stand 2 provided at the bottom of the product storage section 1. Here, the product 3 is relatively heavy, such as a lunch box, and the container 3a thereof is made of a soft synthetic resin member or the like with low strength. The support stand 2 has a piece 2A standing upright on its left end.
and a roller 17.1 provided on this piece 2A.
7, and a rail 5 provided in the space path 16 on the side of the product storage section 1.
This allows the support stand 2 to be moved up and down.

Reference numeral 8 denotes a semicircular cam fixed to the rotary drive shaft 7A, and a guide plate 6 protruding from the middle of the piece 2A of the support base 2 is engaged with this cam 8. During the sales waiting period, the cam 8 is stopped in a horizontal state with the cam surface facing upward as shown in FIG. 1, and the guide plate 6 abuts and locks the cam 8 in this state. On the other hand, the upper end is attached to the side walls 4A and 4B (more specifically, the side surfaces facing each other in the front and back) of the product storage section 1 with a pivot support 18.1.
The product holding plates 9A, 9B are arranged between the rotary drive shafts 7A, 7B and the product 3 so as to face each other with the product 3 in between. And product holding plates 9A, 9
The lower end gripping pieces 9a and 9b of A are the openings 19.1 in the side wall.
Appears from 9 onwards. The drive shafts 7A and 7B have cams IOA for moving the product holding plates 9A and 9B into and out of the product storage section,
The IOB is provided with a phase shift of 90'' with respect to the cam 8. Drive shaft 7A.

7B is link 1 so that it operates in opposite directions with one driving source.
They are connected by 1. A cart 12 for dispensing products is arranged below the support stand 2, and the cart 12 is reciprocated by swinging a link 13 whose one end is pivotally supported. A pusher 12a provided on the trolley 12 pushes out the products 3 to a from the sales passage 14. A stopping member 15 having one end pivotally supported on the cam IOB is provided to cut off the sales passage 14.

Next, the operation will be explained. The drive shaft 7A is moved to the first position by the recording means.
Move in the direction of the arrow in the figure. The cam IOA pushes the product holding plate 9A toward the product storage section, and the operation of the m drive shaft 7A reversely moves the opposing drive shaft 7B at the link 11, and the cam IOB also pushes the product holding plate 9B toward the product storage section. push out

FIG. 2 shows a state in which the drive shaft has rotated 90' from the timing state. The product holding plates 9A and 9B hold the cooked rice products 3 to b. When the drive shaft is further rotated 90 degrees, cam 10A
, the cam IOB rotates while holding the cooked rice products 3 to b. As shown in FIG. 3, the cam 8 rotates 90 degrees and stops while lowering the guide plate 6 protruding from the side of the support base 2. The guide plate 6 is at a point where the stroke is lowered by approximately the radius of the cam 8.
Since it stops when it hits the drive shaft 7A, the sales products 3 to b on the support stand 2 move downward by the stroke.

The restraining member 15 pivotally supported by the cam IOH is completely recessed from the sales passage 14, and the sales passage 14 is opened. In this state, by swinging the link 13 by another cantering source, the cart 12 uses its pusher 12a to push out the sales items 3-b toward the sales passage 14, and returns to its original state. When the trolley 12 returns to the timing state, the drive shaft 7A
