Dispensing device for a machine of supply

Abstract

A dispensing device ( 1 ) for a dispensing machine to supply liquid food products that have a high degree of viscosity such as dairy products in which the product is stored in a container that has an outlet tube in order to be connected to the dispensing device ( 1 ), that is fitted with geared motor ( 3 ) on the inside from which a motor shaft ( 4 ) protrudes and which is fitted to a rotating roller ( 5 ) that has a multitude of “idler roller” ( 6 ) separated from each other but connected to said roller ( 5 ), and a space between the “idler roller” and the external body ( 2 ) having been provided, in such a way that the outlet pipe ( 13 ) passes through the space between the “idler roller” and the external body ( 2 ), in such a way that in its working position the roller ( 5 ) turns supplying the product by means of impulses, whilst in its rest position the outlet tube ( 13 ) is held tightly by applying pressure of the idler rollers ( 6 ) against it.

1 . A dispensing device for a dispensing machine, especially for liquid food products that have a high degree of viscosity as can be the case of dairy products such as yoghurt or similar items in which the dairy produce is stored in a container that has an outlet tube that is located in a lower position in order to be connected to the dispensing device, wherein it has an external body that is fitted with geared motor on the inside from which a motor shaft protrudes and which is fitted to an axially turning roller that on the external cylindrical surface has a multitude of “idler rollers” separated from each other but connected to said roller, and a space between the “idler rollers” and the external body having been provided, in such a way that the outlet pipe passes through the space between the “idler rollers” and the external body, in such a way that in its working position the roller turns supplying the product by means of impulses, whilst in its rest position from the dispensing device the outlet tube is held tightly by the application of pressure from at least one of the idler rollers against it. 
   
   
       2 . A dispensing device according to  claim 1 , wherein the roller body is made from a plastic material that has a first cylindrical section located on the inside of the body and a second section that has two opposing and separated protrusions between which the idler rollers are located. 
   
   
       3 . A dispensing device according to  claim 2 , wherein the second section of the roller is located in the central longitudinal part of the body. 
   
   
       4 . A dispensing device according to  claim 1 , wherein the body is fitted into the supply machine by means of an upwardly directed extension that has an upper flanged section in order for it to be fitted into a housing located in said dispensing machine. 
   
   
       5 . A dispensing device according to  claim 1 , wherein it has a manual activation element for the geared motor located on the lateral end of the body. 
   
   
       6 . A dispensing device according to  claim 1 , wherein it has a hinged protector cap that covers the supply outlet pipe that crosses the dispensing device coinciding with the second roller section.
