Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an abnormality detection device for a vending machine, which detects an abnormal setting of a holding bar that maintains the stacked state of stacked products that are sequentially dispensed during a vending operation. related to a device for

[Conventional technology]

Generally, in a vending machine that sequentially dispenses this type of stacked products, such as a cigarette vending machine, storage sections that store and hold products stacked vertically are arranged in parallel in the left and right direction, and each storage section The configuration is such that the products are dispensed sequentially starting from the bottom row. A holding rod is provided on the product storage opening side of the product stack storage section so that the products are held in a stacked state, and this holding rod rotates so that the storage section can be replenished with products. It can be retracted from the product storage opening surface position, and after replenishing products, the holding rod is returned to the front position of the storage section to hold the stacked products in the storage section.

In the above-mentioned conventional vending machine, if you forget to return the holding rod to the product holding position after storing the products in a stacked manner in the storage section, if you continue dispensing the products, the stacking may occur due to vibration etc. There have been problems in that the stacked state of the products is disturbed, the products fall from the product storage opening of the storage section, and the products become clogged in the dispensing section, making it impossible to dispense them for sale.

Therefore, as described in Japanese Utility Model Publication No. 60-692, when the holding rod is retracted from the storage opening surface of the storage section where products are stacked, the detector is activated and lights up the lamp or sounds the buzzer. A configuration is known in which the holding rod is activated to notify an abnormal state of the holding rod.

[Problem that the invention seeks to solve]

The above-mentioned conventional device can notify the state in which the holding rod has opened the product storage opening surface of the storage section, but the notification means only reports an abnormality in the holding rod, and does not need to be provided separately from the product sold-out notification. However, there is a problem that the number of man-hours required for installation is increased and the configuration becomes complicated.

The present invention has been made in view of the above-mentioned problems, and when the holding rod is retracted from the product storage opening surface of the storage section when replenishing the product, it is assumed that the product is sold out. If the holding rod is not returned to the original position while the storage area is being evacuated, the product will continue to be sold out, and the product in this storage section will be stopped from being sold. The present invention provides an abnormality detection device for vending machines.

[Means for solving problems]

The abnormality detection device for a vending machine of the present invention has a product storage section that stores products in a stacked state, and a holding rod holds one side of the stacked products located at the product storage opening surface of the product storage section. In a vending machine in which the holding rod is rotated to move from the product storage opening surface of the product storage section to a retracted position when replenishing products, a magnetic detection means for detecting the presence or absence of magnetic flux; It is moved integrally with a detection piece that detects the presence or absence of a product, and when the detection piece detects the product, it applies magnetic flux to the magnetic detection means, and when the detection piece does not detect the product, it applies magnetic flux to the magnetic detection means. a shielding member positioned between the magnetic detection means and a magnet imparting magnetic flux to the detection means and shielding the magnetic flux of the magnet when the holding bar is not in a holding state for holding the product; The apparatus further includes a sold-out detection section that outputs a sold-out signal if the magnetic flux of the magnet is not detected by the magnetic detection means.

[Function] When replenishing products, the abnormality detection device for a vending machine of the present invention rotates and retracts the holding rod from the product storage opening surface of the storage section where products are stacked and stored, and removes the holding rod from the opened product storage opening surface. Store products in layers. When the holding rod is retracted from the product storage opening surface, a shielding member that shields the magnetic flux is interposed between the magnetic detection means and the magnet, and since the magnetic detection means does not detect the magnetic flux, the sold-out detection section By outputting a signal to prevent the selling operation and returning the holding rod to the storage opening surface after storing the product, the laminated product is held so that it will not collapse due to vibrations, etc.
In addition, when the holding rod returns, the shielding member retreats from between the magnetic detection means and the magnet, and the magnetic detection means detects the magnetic flux of the magnet, and the magnetic detection means detects the magnetic flux.
The sold-out detection section does not output a sold-out signal, allowing the selling operation, and if the holding rod is forgotten to return after stacking and storing the products, the shielding member is interposed between the magnetic detection means and the magnet. Since the magnetic detection means does not detect magnetic flux, the sold-out detection section continuously outputs the product sold-out signal to prevent the product from being sold and prevent the laminated product from collapsing due to vibration or the like.

Furthermore, when there is a shortage of products in the storage section, the detection piece that detects the presence or absence of products is activated to prevent the magnetic flux of the magnet from bending to the magnetic detection means. This outputs a sold-out signal for the product.
