Abstract
A conveying belt is deflected around a stationary deflection roller and loops around the bottom of a deflection wheel. The deflection wheel is freely rotatably mounted on a lever and is prestressed in the direction towards the deflection roller by a spring element. The conveying belt, driven by a stepping motor, and the deflection wheel form a conveying gap for the products, which are arranged in an imbricated formation. In this formation each product, as seen in the feed direction, bears on the preceding product, with almost complete overlapping. The products form a stack-like supply and are conveyed to the discharge location, with the result that a product is always available there for discharge.
Claims15
An apparatus for the feeding of sheet-like products to a discharge location, the apparatus comprising:
- an endless conveyor belt, the endless conveyor belt having a beginning region and a conveying and load-bearing strand, the beginning region of the conveyor belt receiving the sheet-like products in a feed direction and in imbricated formation such that the products are supported on the conveyor belt on their trailing edges;
- a deflection wheel;
- the conveyor belt guided, at least approximately at the discharge location, around a stationary deflection roller such that the conveying and load-bearing strand loops around the bottom of the deflection wheel, the highest point of the deflection wheel is located at a higher level than the deflection roller, deflection means movably supporting said deflection wheel for applying a prestressing force to prestress said deflection wheel in the approximate direction towards the deflection roller and enable said deflection wheel to be forced back, against said prestressing force, a conveying gap being defined by the deflection wheel and the conveyor belt;
- and
- a drive connected to move the conveyor belt such that the products are conveyed from the beginning region and fed through the conveying gap to the discharge location.
A device for the feeding of sheet-like products to a discharge location and for feeding sheet-like products to a further-processing location, the apparatus comprising:
- an endless conveyor belt, the endless conveyor belt having a beginning region and a conveying and load-bearing strand, the beginning region of the conveyor belt receiving the sheet-like products in imbricated formation such that the products are supported on the conveyor belt on their trailing edges;
- a movably mounted deflection wheel;
- the conveyor belt guided, at least approximately at the discharge location, around a stationary deflection roller such that the conveying and load-bearing strand loops around the bottom of the deflection wheel, the highest point of the deflection wheel is located at a higher level than the deflection roller, a deflection wheel support the deflection wheel being pressed approximately in the direction towards the deflection roller, by said deflection wheel support and capable of being forced away from said deflection roller by said sheet-like products, a conveying gap being defined by the deflection wheel and the conveyor belt;
- a drive connected to move the conveyor belt such that the products are conveyed from the beginning region and fed through the conveying gap to the discharge location;
- a conveying device provided downstream of said discharge location, the conveying device receiving and transporting the products further;
- and
- a sucker arrangement raising a product located at the discharge location and feeding the product into a conveying region of the conveying device.
