Embodiment Construction

[0027] As shown in Figure 1, the moving carriage 1 of the insertion machine is mounted on a conveyor track 2 and runs continuously around the machine. As shown in FIG. 2 , the optical sensor 18 includes a fixed light source 3 and a fixed light detector 4 . The fixed light source 3 and the fixed photodetector 4 are connected with a fixed control device, such as a microprocessor, by wires.

[0028] The fixed light source 3 and the fixed light detector 4 are fixedly connected to the frame of the insertion machine and adjoin the slot 5 on the machine, the slot 5 being carried by the carriage 1 . The first optical fiber 6 has a first lens 8 connected to its first fiber first end 12 and a second lens 9 connected to its first fiber second end 13 . The second optical fiber 7 has a third lens 10 connected to its second fiber first end 14 and a fourth lens 11 connected to its second fiber second end 15 . Fibers 6 and 7 are mounted on groove 5 in a fixed manner. The first lens 8 and t...

Abstract

An optical sensor for detecting the presence or absence of sheet products in a moveable device has a fixed light source, a fixed light detector spaced from the fixed light source, and a light transfer device fixedly connected to the moveable device for directing light from the fixed light source to the light detector as the moveable device passes by the fixed light source. Also disclosed is a device for transferring and moving sheet products and a method for detecting sheet products by an optical sensor having the steps of inserting a first sheet product into a first moveable device, aligning the first moveable device with a fixed light source and a fixed light detector, and transmitting light from the fixed light source across an opening of the first moveable device.

Description

technical field [0001] The present invention relates generally to a sensor for use in a machine with movable parts, and more particularly to a device and method for detecting the presence of a sheet-like product. Background technique [0002] Many machines contain movable parts that move continuously around the machine. For example, a collating machine includes several carriages that run continuously around a loop. Each bracket includes several slots. Products from a fixed product stack are placed in each slot as the carriage operates. [0003] Collating machines can be used to arrange printed matter in a correct order. An inserter is a type of collating machine in which printed matter, such as newspaper chapters, are placed on top of each other. For example, the page numbers or chapters of a book or newspaper must be in the correct order before they can be bound or assembled. Several slots are arranged at regular intervals and are movable along a circular path. Each s...
