Description

  The present invention relates to detection of a product carried out from a product storage unit of a vending machine to a product outlet.

  The vending machine has a product storage column for storing products, and a product transporting device that receives the products sent from the product storage column by the bucket and moves them downward to drop the products to the product outlet. Is provided with a product detection sensor that detects a product dropped from the bucket portion.

  When a user inserts a coin into the coin slot of the vending machine and presses a product selection button, a sales command signal is output. Based on the sales command signal, the product selected by the product selection button is displayed. The bucket portion is moved to a position corresponding to the stored product storage column. When the bucket part moves to a position corresponding to the product storage column in which the selected product is stored, the product delivery mechanism equipped in the product storage column operates to push the product in the product storage column forward. The product in the front row falls on the bucket part. And if a bucket part moves below and reaches the lowest part, goods will fall from a bucket part to a goods take-out mouth. When the product falls to the product outlet, the product detection sensor provided at the product outlet detects that the product has dropped to the product outlet. When the product detection sensor detects that the product has dropped to the product take-out port, the bucket unit moves upward and stops at the top to enter a sales standby state for the next sales operation (see, for example, Patent Document 1). .
