摘要:
A conveyor device comprising a guiding rail for guiding at least one transport mechanism. A ferromagnetic guide, including a magnet, is fixed to the guiding rail. An article carrying part is detachably connected to the transport mechanism through a magnetic circuit that flows through two spaced apart ferromagnetic guide parts carried by the transport mechanism. The ferromagnetic guide and the ferromagnetic guide parts are located relative to each other such that there is an air gap there between through which the magnetic circuit flows to create an attractive force, Fm, holding the article carrying part on the transport mechanism.

Method and apparatus (1a) for optical detection of the position of large-area printed products (10). The apparatus (1a) has conveyance means (2a) for movement of the printed products (10) along a conveyor path (4) past at least one contrasting light source (30), and at least one optical sensor (16). The conveyance means (2, 2a), the contrasting light source (30) and optical sensor (16) are arranged such that the printed products (10) can be conveyed between the contrasting light source (30) and the optical sensor (16).

The invention concerns a movable object, e.g. a roll of printed products (1) with a winding core (2) onto which printed products are wound with the help of a winding tape (3). The inventive movable object carries data stored in an integrated circuit (23) and an antenna, whereby the data can be read or overwritten respectively without contact by a reading/writing device with a main reading direction (L). The antenna is designed as an antenna loop (5) with a gap, whereby the ends of the loop (5) are contacted with the integrated circuit which is e.g. arranged on a connecting piece and whereby an antenna area is defined by the antenna loop (5). The object is position able relative to the reading/writing device (10) such that the main reading direction (L) penetrates the antenna area vertically or obliquely.

A clamping element for attaching a gripper onto a clamping tongue as well as a gripper with this kind of clamping element is provided. The clamping element has a longitudinal carrier the width of which substantially corresponds to the width of the clamping tongue and at least two mutually distanced clamping regions. At least one fastening element for the detachable fastening of the clamping elements to the clamping tongue (42, 44) is provided. The clamping element provides an improved force division as well as a secure support on the clamping tongue.

The device (10) according to the invention for counting and detecting flat products (14) comprises a light source (16) having an illumination beam profile (24), an optical sensor (18) having a detection beam profile (30) and an evaluation unit (20) connected to the optical sensor (18). The detection beam profile (30) overlaps the illumination beam profile (24) in a detection region in which a section (33) of a surface profile of the flat products (14) is illuminated, the section being at least partially delimited by the illumination beam profile (24). A detection signal generated by the optical sensor (18) is fed to the evaluation unit (20), which determines therefrom the number of flat products located in the detection region.
摘要:
A static charge is produced on surfaces of superimposed, flat articles (2) by passing the superimposed articles (2) through an electric d.c. voltage field that is oriented substantially perpendicular to the principal surfaces of the articles. Due to the charging, electric forces of attraction between the surfaces of the articles increase the mutual adhesion of the flat articles. The effect of the static charging is reduced or prevented for at least one of two surfaces participating at a predetermined separation point, by treating the surface beforehand with an anti-static agent (3). Due to the anti-static agent there is little or no charge concentration on the surface such that there is little or no increase in adhesion at the separation point. Thus, at the separation point it is possible to displace the articles against one another with much smaller force expenditure than is required to displace the articles at non-separation points. The method is particularly suitable for opening multipage printed products between two predetermined pages.

The invention concerns a clamping element (1) for attaching a gripper (42, 44) onto a clamping tongue as well as a gripper with this kind of clamping element (1). The clamping element (1) has a longitudinal carrier (10) the width of which substantially corresponds to the width of the clamping tongue (42, 44) and at least two mutually distanced clamping regions (20, 20′). Besides at least one fastening element (30, 30′) for the detachable fastening of the clamping elements (1) to the clamping tongue (42, 44) is provided. By means of the invention an improved force division as well as a secure support on the clamping tongue is achieved.
摘要:
The invention relates to a method as well as to a conveyor-technology device for processing printed products. The conveyor-technology device comprises a guide means and conveyor means which may be moved along the guide means, for conveying printed products which are fed by way of feeders. The guide means is curved in several spatial directions. The conveyor-technology device comprises holding means which serve for the temporary fixing of printed products in a manner such that these at least in regions may be conveyed against gravitational force.
摘要:
A counting device associated with a conveying device for conveying flexible flat objects, such as printed products, in an overlapping stream. The counting device includes a slide mounted for forward and return movement along a guide which extends in the conveying direction, and a drive is provided for moving the slide along the guide at a higher speed than the conveying speed. The slide mounts a flexible contact element which engages the objects, and a sensor element which is engaged by the contact element when the contact element is deflected by engagement with a rear edge of each object, as the slide is forwardly advanced. A catch element, which is also mounted to the slide, then comes into contact with the rear edge of the object to displace the object in the conveying direction.
摘要:
An apparatus for counting flexible flat objects, such as printed products, which are conveyed in an overlapping formation. A detection device counts the objects as they are being conveyed, and comprises an insertion element which is moved in the direction of conveyance at a speed greater than the conveying speed of the objects so as to catch up with an object and interact with an end section of the object, and a detection element which emits a signal to a counter when the insertion element interacts with an end section of an object.
