Definitions

the invention relates to a securing device for the roller support frame supporting the upper belt run in tape stores, which can be fixed in both positions by means of a swivel unlocking and locking device from the belt deflection carriage traveling under this by means of roller cam guides by means of a pivoting movement from a rest position into a working position and back are.
the devices work with latch disks rotatable about the pivot axis of the roller support frame and having latch recesses assigned to the working position or the rest position and latch actuating latch levers which can be acted upon and which are controlled via shift rollers by guide strips arranged on the belt deflection carriage.
roller cam guides in which rollers arranged on the roller support frame are detected by cam tracks arranged on the belt deflection carriage and positively guided during the carriage movement, reliably guarantee timely pivoting away of the roller support frame and the support rollers held by them from the working position into the rest position and thus out of the movement path the belt deflector;
the prerequisite for this, however, is the fixing of the roller support frame in the respective position by the device for swivel unlocking and locking, since this also determines the respective entry position of the guide rollers of the roller cam guides arranged on the roller support frame.
the roller support frames are not fixed in the respectively intended position, but remain in an intermediate position and may be pushed to the side in the direction of their rest position by the belt deflection carriage without causing harm; are then in an unpredictable position in the trajectory of the conveyor belt when it returns and cause collisions with the corresponding consequential damage.
the pivot axes of the roller support frames have predetermined breaking points that become effective in the event of such faults. With these predetermined breaking points can be uncontrolled The pivoted positions of the roller support frames within the movement path of the belt truck cannot be avoided.
the invention has for its object to ensure after occurrence of damage of the type described that the roller support frame regardless of the pivoting and locking devices or the roller cam guides in the sense of their predetermined task or not, the pivoting back of the roller support frame in their rest position and the setting is guaranteed in this rest position.
This object is achieved in that in the movement path of fixedly connected to the belt deflection guide rails on the roller support frame stop elements are arranged, which can be acted upon by the guide rails at a distance from the swivel movement path of the roller support frame determined by the roller cam, and by in the direction of Pivotal movement path arranged behind the roller support frame rest position, which detects and fixes the roller support frame.
the invention further provides, arranged on the belt deflection carriage, the stop elements of the roller support frame during its travel movement, before the guide rails can act on shock absorbers, dampen the impact of the guide rails on the stop elements and cause a smooth initiation of the pivoting movement of the roller support frame in the direction of the rest position .
the belt deflection roller 1 carrying the belt deflection carriage 2 is provided on its two longitudinal sides with a first pair of guide strips 13 which, when the belt deflection carriage 2 moves in one or the other direction of the double arrow P, actuates the switching rollers 3 and 4 of the pivoting and locking device 5, respectively Help the two roller support frames 6 in the (drawn) rest position or (dash-dotted lines) work position to be determined.
the pivoting movements of the roller support frames 6 are positively controlled by guide rollers 7 arranged on them, which run into the curved guides 8 arranged on the belt deflection carriage 1.
roller support frame 6 On the roller support frame 6 abutment elements 9 are arranged, which are in the working position of the roller support frame 6 (dash-dotted) in the path of movement of the two further guide strips 10 on the belt deflection carriage 2. These guide strips 10 are still the bump Damper 11 with buffers 11a, which are also arranged on the belt deflector 2, assigned.
roller support frame 6 in the dash-dotted swivel position or in another swivel position within the path of movement of the belt reversing carriage 2 and the guide rollers 7 in cooperation with the cam guides 8 are not able to bring the roller support frame 6 out of the movement path of the belt deflection carriage 2 before it enters the area of the roller support frames 6, then these are first pivoted by the buffers 11a of the run-up shock absorbers 11 and then by the action surfaces of the guide strips 10 by acting on the abutment elements 9 in the direction of the holding devices 12 until they are in a holding position over the full lines shown rest position, as also indicated by dash-dotted lines, detected by the holding devices 12 and held in this holding position.
the guide strips 10 are positioned on the belt deflection carriage 2 opposite the curve guides 8 so that they become active in the course of the travel movement of the belt deflection carriage 2, at a distance from the swivel path of the roller support frame 6 determined by these curve guides 8, and act on the abutment elements 9 when due to a malfunction or a break, the roller support frames 6 are still in their path of movement on the belt deflection carriage 2.
