Adjustable length conveyor
First Claim
1. An adjustable conveyor for conveying articles, the adjustable conveyor comprising:
- a frame;
a first track including a first conveyor belt;
a second track including a second conveyor belt;
the first track and the second track being mounted on the frame so that the first track and the second track are parallel to each other;
each of the first track and the second track includes a first element and a second element that are slidably connected to each other so that a space between the first element and the second element is adjustable so as to change a length of the respective track; and
each of the first and second tracks includes a plurality of guides that are slidably mounted on the respective track in an overlapping manner so that an amount of overlap between the guides is adjusted as the space between the first element and the second element is adjusted.

Abstract
An adjustable conveyor for conveying a printed circuit board includes a frame, a first track including a first conveyor belt, a second track including a second conveyor belt, wherein the first track and the second track are mounted on the frame so that the first track and the second track are parallel to each other. Each of the first track and the second track includes a first element and a second element that are slidably connected to each other so that a space between the first element and the second element is adjustable so as to change a length of the respective track. Each of the first elements includes a plurality of slide blocks. The slide blocks are slidably mounted on the first elements in an overlapping manner so that an amount of overlap between the slide blocks is adjustable as the space between the first element and the second element is adjusted. The conveyor also includes a device for simultaneously driving the first and second conveyor belts.

15. An adjustable conveyor belt assembly used for conveying printed circuit boards, the adjustable conveyor belt assembly comprising:
-
a conveyor belt;
means for supporting the conveyor belt, the supporting means including a first element and a second element that are slidably connected to each other so that a space between the first element and the second element is adjustable so as to change a length of the adjustable conveyor belt assembly; and
guide means mounted on the supporting means for guiding the conveyor belt along the supporting means, the guide means including a plurality of slide blocks that are slidably mounted on the supporting means in an overlapping manner so that an amount of overlap between the slide blocks is adjusted as the length of the adjustable conveyor belt assembly is changed. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24)
