DE2254096A1 - STACKING MACHINE FOR MAGNET-FREE STACKING - Google Patents

Description

PRIOR ART High-performance stacking machines with operationally reliable Gear for fine iron profiles with sufficient capacity are not known to this day.

Magnet-free stacking has long been the wish of many rolled steel producers, since many customers of the rolled products refuse to magnetize the products.

Demagnetizing requires additional expenditure of time and money, which is understandably undesirable.

Stacking machines for non-ferrous material with reliable operation are also not known.

DESCRIPTION OF THE STACKER General - The rolled profiles coming from a counting device, which are collected to the width of a stack, run into the stacking machine via a roller table or a Wimmler and are stacked into stacks by this.

STRUCTURE AND FUNCTION Structure - (Fig. 1 and 2) The stacking machine system consists of a certain number of gear racks arranged one behind the other, in which two different swivel lever systems are rotatably and displaceably mounted (see Fig. 1 and 2, pos. a + b). These latter swivel lever systems swivel the stacking position by 180.

The gear racks are connected to each other by means of electro magnetic couplings disconnected connected. It is driven by one, depending on the length of the stacking system or two pages. A reduction gear is connected upstream of the DC motor.

The transfer carriages (g) are located between the gear racks at certain intervals arranged. These transfer vehicles transfer the stacking position to the stacking table without turning (k).

The transfer trolley is moved by hydraulic cylinders.

FUNCTION (Fig. 1 and 2) Fig. 1 Representation I stack position is on the Roller table "1" has run up, guide lever b is by means of drive "e" and "c" over the Stacked position swiveled.

Illustration II swivel lever systems "a" and b are non-positive Connected via electro-magnetic couplings (p) (Fig. 2) and pivot the stack position by 180 ° over the stacking table "k" to the deposit, swivel lever "a" is locked by means of a locking cylinder "r" (Fig. 2) prevented from moving axially when pivoting.

Illustration III Stopper "m" is brought into the appropriate position.

The stacking layer is placed on the stacking table "k" by the simultaneous retraction of the swivel lever systems, swivel lever a is through Cylinder "f" is withdrawn, guide lever "b" is withdrawn by its own drive "c", Guide lever b is designed as a rack and is driven by an electric gear motor withdrawn.

Illustration IV stacking position can be continuously without hindrance Pass roller table 1.

Illustration V The transfer car "g" is in the starting position Pos. 1 under the run-up roller table "l", which is now the stacked layer lifted by the transfer carriage in pos. 2 (by means of the parallel rocker arm).

This pivoting back is required to move over the guide and Conveying away the stop part of the pivot lever a.

In order to be able to carry out the "pivoting back" (lifting) safely, the guide wheels are stopped for a short moment by means of locking cylinder "n" '(see Fig. 2 detail of the transfer car "g").

The lifting cylinder "i" now pushes the stack layer over the stacking table "k" which is reached by pulling back the lifting cylinder "i" in pos. 3 (lowering).

The adjustable stopper "h" was swiveled over the stacking layer and now stops the stack to be deposited.

The transfer car is now continuously withdrawn. At this Movement slide the individual profiles down onto the stacking table "k".

Illustration VI After the upper carriage "g" has reached its starting position Pos. 1 has reached again, the adjustable stopper h 'swivels back.

The force-locking of the electro-magnetic clutches "p" is canceled (Fig. 2).

The drive "e" switches on and swivels over a spur gear "o" the swivel lever b with simultaneous drive "c" (move) over the already returned new pile.

Pivoting around 1800 over the stacking table by frictional locking of all electro-magnetic clutches.

Main drive switched on, etc. analogous to II.

OUTSTANDING FEATURES OF THE STAPE2IASCHI E With the stacking machine for Magnet-free stacking, fixed packs can be achieved, the U and angle profiles nested stacks, i.e., there? every second bar shelf is mechanically turned around 1800 is placed on the package.

The cycle time is particularly short, because the stack material without a break can run in continuously, which results, among other things, in the extremely high performance.

1 stacking system is sufficient in most cases for a fine iron mill.

The stacking table can be raised and lowered; it can also be moved sideways, in order to be able to do justice to different stack widths.

The undesired magnetization of the stack material is excluded. Non-ferrous material can also be stacked.

The stacking system works automatically and can be used in fine and medium iron mills can be used.

The very low and compact design of the stacking system hinders existing ones Hardly any hall cranes over the stacking system.

Claims (1)

PROTECTION CLAIMS "Stacking machine for magnet-free stacking (Fig. 1 and 2) The invention is characterized in: Fig. 19 (I) to (1V) 1) a) that the material to be stacked, as shown in Fig. 1, runs over the pivot lever a and the guide lever "b" pivots over the stacked material; b) ending (panning around 1800) is done by swiveling both lever systems "a" and "b" at the same time; c) the stacking layer is deposited by pulling back both lever systems at the same time a and "b"; d) the pivot lever system "a" remains in this position and is for free a new work cycle; Fig. 1, (V) to (VI) e) the position not to be turned is moved over the stacking table by means of an upper trolley flgll via a rocker lever system. Stopper "h" swings over the stacking layer; the stacking layer is deposited through Withdrawing the transfer cart "g"; f) Guide lever "b" swivels over analogously to 1a) the, batch material - new work cycle begins.
