SU33058A1 - Cardboard Reel Machine - Google Patents

Description

For the manufacture of cardboard coils from cardboard tape, nailed onto a rectangular mandrel, with cheeks lying on the spool, automatic machines are used which have a turntable with mechanisms fixed on it that perform individual operations; at the same time, the table makes at its full turn the number of stops equal to the number of operations.

In the proposed machine, related to the specified type of machine, in order to automatically stop the machine in the event of running out of the cheeks in the magazine, the clutch is disengaged by automatically turning the axis of the disengaging lever.

In FIG. 1 is a perspective view of the automatic shutdown of the machine; FIG. 2 is a perspective view of a cheek magazine; and FIG. 3-circuit automatic shutdown.

In the proposed automatic machine for making cardboard reels intended for various small electrical equipment {relays, small transformers, etc.), 1 pressped cardboard or paper tape fed from the reel and finished stamped cheeks coming from

shops. The number of cheeks can be different, i.e. coils having only extreme or also intermediate cheeks can be made. The whole process is divided into the following operations: 1) winding the spool, sizing it and cutting off the tape, 2) putting on the cheeks, and putting on each cheek represents a separate operation, the number of which corresponds to the number of put on cheeks, 3) lubricating the main cheeks, 4) removing tie with automatic and drying.

To perform these operations, the machine has a circular rotary table equipped with spindles that can rotate around their longitudinal axis; individual operations are controlled by shafts with cam loops.

The connection and rotation of the table and the spindles can be carried out both from the transmission and from a separate drive, using a device for changing the speed, depending on the type of product, for which a Norton box or other similar device can be used. The machine is turned on and off by a gear or friction clutch 3. The machine is turned off when the supply of cheeks in the magazine 76 is exhausted as follows. The shaft 5 (Fig. 1), to which the rigidly switching lever acting on the coupling coupling 5 is connected, is connected by means of ball joints to the shafts 5 (Fig. 3), located opposite the stores for cheeks. Turning one of the pieces of this shaft system causes the lever to turn - and the machine stops. To make this stop, levers 85 are provided, shafts 5 freely attached to I 5. Levers 85 can rotate freely in one direction, j in the opposite direction, turning the lever causes the shaft to turn 5 j using the existing ratchet | devices. With clutch 3 turned on, all levers are held in the determined position by latches 84. When the toe 83 is pushed onto the lever 84, the latter is pressed out, releasing the lever 85, which is then pulled away by the spring 86.

When this happens through the ratchet device, the shaft 5 is turned off and the clutch 3 is turned off, i.e. the machine stops.

The subject of the patent.

An automatic machine for making cardboard reels (spools) made of cardboard tape, wound on a rectangular mandrel, with cheeks glued to the bobbin, consisting of a circular rotating table with a number of individual mechanisms fixed on it, a number of processing operations, and a number stops, equal to the number of processing operations, characterized in that when the store of cheeks in the magazine is exhausted, the machine is automatically stopped by turning off the clutch 3, automatically .5 th turning the switching-off lever 4.
