DE479110C - Switching memory, especially for mountains of waste - Google Patents

Description

There are already different types of switch memories, i.e. devices that have a Can record series of switching operations and these later automatically depending on any operating processes return. These Schaltapeicher exist mostly of two rotating parts, one of which is the one in question when storing Receives switching pulse and is moved forward by one division, while the other lags behind during delivery and the Impulse passes on.

There are also devices known in which the drums in opposite directions Directions are rotatable. There are also already known switch memories, in which the storage and the decrease of the stored orders from one and the same device, the rotatable trip

ao voter, was exercised and it was proposed, either this trip voter or to arrange the drum rotatably.

These constructions result in nested parts that are difficult to access and are confusing and cannot be monitored in the company.

According to the present invention, there is a simpler and more reliable switching memory created in that the storage takes place on a fixed drum, around whose axis the stepping mechanisms rotate, one of which is the storage and whose other worries about the decrease.

In the following, the device according to the invention is described with reference to the two schematic figures. For the sake of simplicity, only two switching operations A and B are assumed here. The storage is carried out by the magnet a, the armature of which is provided with a (stepping) pawl b , which engages in the stepping mechanism c. The movement of the wheel c takes place with the help of the pawl b through the spring d when the magnet α is de-energized and the spring d pulls off the armature. This has the advantage that a simple contact device is sufficient for the actual switching operation, because when the magnet α is switched on, the switching magnet e can also be switched on at the same time. . The switching magnet e is attached to the switching wheel c and serves to influence the pins /, which are resiliently mounted in the stationary drum g , according to the switching pulse. The changeover switch h on the other side of the drum, which is attached to the second indexing wheel k, is actuated by the pins /. This wheel k is moved on by the magnet I , which is triggered by the operating processes in question. As the wheel k continues to rotate , the switch h is controlled by the pins, depending on whether its role is above a pin that has been pushed in or out. In this way, the accumulations of

The drum is released again, whereby storage and removal can take place at the same time. So that no over-storage can occur, a contact device / M ₁ and m _{2 is provided} on the two switching wheels c and k , which also, since the contact / Tz _{1 is} bipolar , indicates the rest position of the switching memory.

How this switch memory works

ίο is as follows:

If the magnet α receives current by closing the relevant contact, it attracts its armature with the indexing pawl b so that it is in the next tooth gap of the indexing wheel c . By tightening the armature, the tension spring d is tensioned at the same time.

The respective pin / in question for the storage has previously been pressed into the storage drum - against the pull of its spring. This is effected ti by a c at Schritts'chaltrad fixed endpiece that the Speicheras c in the rotation of the wheel on the edge of the drum along grinds and each pin -, pushes before it comes into question for the accumulation in the rim of the storage drum. In this position, each pin is held in place by the cam p, which sits on a leaf spring ο. The pressed-in position of the pins / is intended, for example, to trigger switching process A.

If the switching process A is now required for the storage, then all the preconditions for this have already been met. If the magnet a is de-energized again and the stepping mechanism c is pulled further by one tooth pitch by the spring d, the pin / is still held in place by the leaf spring ο with its cam ρ .

For switching operation B , on the other hand, the already mentioned switching magnet e is required, which in this case is triggered together with magnet α. If the magnet e receives current, it attracts its armature with the spring pin r attached to it. This spring pin r moves the leaf spring ο so high that the pin / is pushed past the cam ρ by the pressure of its spring out of the storage drum. If the switching magnet e is de-energized again together with the magnet α , the spring pushes the spring pin r with the armature back into the basic position.

The accumulations are released automatically by the operating processes that trigger the magnet / and thereby actuate the second indexing wheel k with the switch h , which is controlled by the pins / when the wheel k is moving. The pins / initially remain in the same position after the output of their switching impulses; However, before they receive a new switching pulse, they are brought back to the basic position using the approach η hi. When all accumulations have been released from the storage drum, the rest position is indicated by the contact device m ₁ and m _2.
