Problems solved by technology

[0003] The laser is arranged externally, at some distance from the carriage, so some errors in this optical positioning cannot be eliminated
[0004] The disadvantage is that the current position of the carriage cannot be reported when the carriage is moving towards the sliding platform
So there is no way of knowing exactly how the carriage is positioned on the sliding platform or exactly where
Another disadvantage is that the laser must be arranged to be movable

Embodiment Construction

[0017] Figure 1 shows a conveying device 1, such as a sliding platform, which is moved in the direction of the double arrow 4 by means of a guide roller 3 driven by an electric motor 2, a roll handling unit (not shown here), such as a roll changer , close to or away from the conveying equipment. On the conveying device 1, the carriage 6, also called a trolley, can move in the direction of the double arrow 5 (see figure 2 ). The carriage 6 , loaded or not loaded with the wound reel 7 , is initially moved up to the conveyor 1 by means of externally fixed, driven conveyor rollers 19 ; 20 , arranged for example under the floor. The outer conveyor rollers 19; 20 move the carriage 6 onto the conveyor 1 via the conveyor rollers 9 driven by the electric motor 8 and arranged on the conveyor 1 as long as the carriage 6 remains on these conveyor rollers 19 ; 20 , the externally driven conveyor rollers 19 ; 20 assist in moving the carriage 6 onto the conveyor 1 . Before the carriage 6 ...

Abstract

In combination with a transport mechanism that includes a plurality of conveyor rollers, an apparatus is used to position a carriage loadable with a wound reel at a desired location on the transport mechanism. The apparatus includes a rotary pulse generator associated with one of the plural conveyor rollers for registering the revolutions of the one of the plural conveyor rollers wherein the revolutions embody a measure of the distance traveled on the transport mechanism by the carriage. The apparatus also includes at least a first and a second initiator for determining the current position of the carriage on the transport mechanism. The first initiator detects a first position of the carriage. The second initiator detects a second position of the carriage. The revolutions of the rotary pulse generator and a distance between the first and second initiator are used to calculate a slip (K), which is used to determine distance (W) between the current position of the carriage and the desired position (S) of the carriage.

Description

technical field [0001] The invention relates to a positioning device for a pallet according to the preamble of claim 1, wherein the pallet is used for loading or unloading rolled rolls. Background technique [0002] De 43 34 582 A1 discloses a reel changing device in which the movement of the carriage with the reeled reel into position is determined by a laser, which is movable and arranged above a sliding platform. For this purpose, the laser is moved to the position calculated for the carriage by the computer of the reel changer, and when the calculated position is reached, the leading edge of the carriage is registered with the laser and at the same time a signal is sent to the computer of the reel changer that the carriage has been The calculated position is reached. [0003] The laser is arranged externally, at some distance from the carriage, so some errors in this optical positioning cannot be eliminated. [0004] The disadvantage is that the current position of the...
