Abstract
Two belts 20a and 20b disposed perpendicularly to a bottom belt 10 passed round and driven by a pair of pulleys 11 and 12, have profile members 23 for accelerating or decelerating conveyed matter conveyed on the bottom belt 10 in contact with the leading or trailing end of the conveyed matter, thus permitting conveying of successive items of conveyed matter at a predetermined conveying interval without clamping the conveyed matter and independently of the thickness of shape thereof.
Claims18
A conveying interval adjusting apparatus comprising:
- a bottom belt movable at a predetermined speed in the direction of conveying conveyed matter;
- and
- at least one belt disposed perpendicularly to the bottom belt, the at least one perpendicular belt having profile members for selectively accelerating and decelerating the conveyed matter conveyed on the bottom belt, thereby increasing and decreasing a conveying interval of the conveyed matter.
A conveying interval adjusting apparatus comprising:
- a bottom belt movable at a predetermined speed in the direction of conveying conveyed matter;
- and
- two belts each having profile members are disposed in parallel and driven alternately and independently and are disposed perpendicularly to the bottom belt, the profile members accelerate or decelerate the conveyed matter conveyed on the bottom belt, thereby adjusting the conveying interval of the conveyed matter.
A conveying interval adjusting apparatus comprising:
- a bottom belt movable at a predetermined speed in the direction of conveying conveyed matter;
- and
- two belts each having profile members are disposed in parallel and driven alternately and independently, are disposed perpendicularly to the bottom belt and are each driven by a pair of pulleys which are coaxial or a same axis with pair pulleys, respectively, for driving the other, the profile members accelerate or decelerate the conveyed matter conveyed on the bottom belt, thereby adjusting the conveying interval of the conveyed matter.
A conveying interval adjusting apparatus comprising:
- a bottom belt movable at a predetermined speed in the direction of conveying conveyed matter;
- and
- two belts each having profile members are disposed in parallel and driven alternately and independently, are disposed perpendicularly to the bottom belt and are each driven by a pair of pulleys which are coaxial in a same axis with pair pulleys coupled by synchro-belts to drive motors, respectively, for driving the other, the profile members accelerate or decelerate the conveyed matter conveyed on the bottom belt, thereby adjusting the conveying interval of the conveyed matter.
A conveying interval adjusting method for adjusting the conveying interval of conveyed matter, comprising the steps of:
- driving a bottom belt at a predetermined speed in the direction of conveying the conveyed matter;
- and
- selectively accelerating and decelerating the conveyed matter by causing profiles on at least one perpendicular to the bottom belt to contact with one of leading and trailing ends of the conveyed matter.
