With the above configuration, beverage products (not shown) in paper packs are stacked and stored in the product rack 5, and the products dispensed from the product rack 5 at the time of sale are placed on the product carry-out conveyor 7. After being dropped, the product is conveyed forward and sent from the front end of the conveyor to the product take-out port through the product carry-out port 4.

  Next, the conventional structure of the above-mentioned commodity carry-out conveyor 7 is shown in FIGS. This product carry-out conveyor is a so-called scraper-type chain conveyor (see, for example, Patent Document 1). In each figure, 8 is a pair of left and right outer frames that are U-shaped in cross section, and 9 is an outer frame 8 having an upper surface as a conveyance surface. A sheet metal shooter body laid on the inside, 10 is a left and right wing shooter extending upside down from the upper edge of the outer frame 8, and 11 is a front end of the shooter body 9 from the front end of the shooter body 9 toward the product outlet 4. And a front shooter 12 extending obliquely downward, and a rear shooter extending obliquely upward from the rear end of the shooter body 9. Further, 13 is a chain mechanism assembled so as to circulate around the shooter body 9 along the left and right sides of the shooter body 9, 13a is a sprocket arranged at the front and rear of the shooter body 9, and 13b is between the front and rear sprockets 13a. The chain 13c is a drive motor for the chain mechanism 13. Further, in the chain mechanism 13, push rods (scrapers) 14 that are installed between the left and right chains 13 b and convey the product received on the conveyance surface of the shooter body 9 forward are arranged at an appropriate interval pitch. These constitute a product carry-out shooter 7.

Moreover, the following trouble countermeasure is given to the said goods carry-out conveyor 7. As shown in FIG. In other words, if the container of a paper pack product containing beverages (milk, syrup, coffee, etc.) stored in the product rack 5 is torn due to some trouble and the content beverage leaks out, the beverage spills onto the product carry conveyor and the chain described above The mechanism 13 may be wetted. Moreover, if the liquid beverage adhering to the chain mechanism 13 is left unattended, the liquid will dry and solidify over time, hindering the movement of the chain mechanism. In the worst case, the chain mechanism 13 will lock and carry out the product. There is a risk that it will become impossible.

  Therefore, as a countermeasure against the above-mentioned problem, in Patent Document 1 described above, the tip of the left and right wing shooters protrudes in a bowl shape to cover the upper side of the chain mechanism, and beverages spilled on the shooter 10 do not wet the chain mechanism 13 directly. Such a structure is disclosed. Further, the conventional product carry-out conveyor 7 shown in FIG. 4 is also formed with a groove 9a having a V-shaped cross section at the front side of the chain 13b along the left and right sides of the shooter body 9 as shown in FIG. Before the beverage spilled on the transport surface of the shooter main body 9 spreads to the chain mechanism 13, measures are taken to prevent the liquid beverage from adhering to the chain mechanism 13 by escaping into the groove 9 a. ing.

The liquid that has flowed into the groove 9a of the shooter body 9 travels along the groove and drops to the bottom of the inside of the cabinet. This type of vending machine includes a cooler (freezer A drain drain tray is laid at the bottom of the inside of the cabinet in order to drain the defrosted water generated in the evaporator to the outside of the cabinet, and drinks dripping from the ridges 9a are also received by this tray. Because there is no particular problem.
JP-A-9-251573

  By the way, the structure which formed the ridge groove 9a (refer FIG. 5) along both the right and left sides of the shooter main body 9 as mentioned above, and poured the drink spilled on the conveyance surface of the shooter main body 9 into the groove | channel, and escapes it. Thus, although it is possible to prevent the beverage from adhering to the chain mechanism 13, it has been found that there are the following problems in terms of maintainability. That is, the beverage that has flowed down into the trough groove 9a is solidified as time passes, and the beverage trough is stuck to the bottom of the groove.

For this reason, when wiping and cleaning the shooter transport surface of the product carry-out conveyor 7 as a daily maintenance work of the vending machine installed at the location, there is a problem that the beverage cake stuck to the groove bottom of the ridge groove 9a is difficult to wipe off. There is a demand for improvement.
The present invention has been made in view of the above points, and while improving the maintenance workability at the time of cleaning the conveyor, the beverage spilled on the transport surface of the shooter body escapes from the system and adheres to the chain mechanism of the conveyor. An object of the present invention is to provide a vending machine product carrying conveyor improved so as to prevent it.

In order to achieve the above object, according to the present invention, the product rack and the product take-out port are linked to each other and arranged at the bottom of the product storage, and the product discharged from the product rack is sent to the product take-out port. The vending machine is a product carry-out conveyor, and lays a chain mechanism that circulates around the left and right sides of the sheet metal shooter body with the upper surface as the conveying surface, and between the left and right chains of the chain mechanism In the structure where the push rod that spans the transport surface of the shooter body is installed across the bridge, it leaks from the product on the near side of the chain along the left and right sides of the flat transport surface of the shooter body. A discharge hole for allowing the spilled beverage to flow out on the transport surface of the main body of the shooter is perforated (Claim 1), wherein the discharge holes are arranged in an array or a staggered pattern on the shooter book. Punching and formed on the plate surface (claim 2).

According to the above configuration, the beverage spilled on the transport surface of the shooter body can be released through the discharge holes drilled in the left and right sides of the shooter body on the near side from the laying position of the chain mechanism. Therefore, troubles that cause malfunction of the chain mechanism due to adhesion can be prevented.
In addition, this discharge hole is punched on the flat transport surface of the shooter body (made of sheet metal), so that it can be transported without leaving stickiness in the beverage bowl compared to the conventional structure in which the shooter body has a V-shaped groove. The surface can be easily wiped and cleaned, improving maintenance workability.
