SU33059A1 - Cardboard Reel Machine - Google Patents

Description

For the manufacture of cardboard coils intended for various small electrical equipment (relays, small trp 1nsformers, etc.), automatic machines are used, which have a rotary table with mechanisms fixed on it to carry out individual production operations.

In the proposed machine, referred to the indicated type, the device for putting the stamped cheeks onto a cardboard tape spool, wound on a rectangular mandrel, consists of a rectangular sleeve with spring surfaces, the cheeks clamped in the holes of the three frames and between them. and the whole device moves to the slider to move the frames with the cheek from the sleeve to the / -shpool.

In FIG. 1 is a perspective view of a cheek shop; FIG. 2, perspective view of the liner with frames; FIG. 3 is a longitudinal vertical section of the sleeve and FIG. 4 is a perspective view of the device for pulling the cheeks onto the spool (in a position moved apart for clarity).

The raw materials used are pressboard cardboard or paper tape fed from the reel, and ready-made stamped cheeks coming from stores, with the number of

cheeks can be different, i.e. coils can be made with only extreme or intermediate cheeks. The whole process is broken down into the following operations; 1) winding the bobbin, sizing it and cutting off the tape, 2) putting on the cheeks, where each cheek is a separate operation, the number of which corresponds to the number of cheeks put on, 3) lubricating the main cheeks with glue, 4) removing it from the machine and drying it.

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

The pre-stamped cheeks are placed in the magazine 76 (Fig. 1), in which the cargo / 8 moved by the tension of the load / 8 is pressed towards the outlet by means of the flap 77. The cam mechanism 8 /, 82 controls the flap 79 and pushes the front cheek through the prot 80. The flap 77 is connected with the flap 77, which is designed to act on the mechanism for stopping the machine when the entire stock of cheeks is consumed.

Putting on the cheeks is carried out using the device represented

in fig. 4 / dl with clarity and extended form.

Guide sleeve 61, consisting of several thin leaf springs, enters inside frames 75, 65 that can move along the sleeve, with the window in frame 75 somewhat narrower than in frame 65. The purpose of the frame 75 is to compress the plates of the sleeve 61 when passing through a hole in the cheek and let go when they push the sleeve 61 on the spool before putting it on the last cheek. The purpose of the folding frame 66 is to hold the cheek before placing it in place.

The entire device is controlled by the respective cam washers and levers and performs the following movements: 1) under magazine 76, with the sleeve 61 bent backwards, 2) the cheek from the magazine is moved between frames 65vi66- the sleeve 61 moves forward, and its plates expand, 3 ) the whole system moves forward, with the plates 61 covering the spool, 4) the sleeve 61 remains in place, the frame system 75, 65, 66 brings the cheek to the nozzle, while the cheek comes off the sleeve 61, 5) the frame 66 flips to the side, 6 ) Sun system is moving away

back, at the same time, the frame 66 is in place, and the sleeve 61 settles back, freeing up space for the next cheek.

The subject of the patent.

An automatic machine for making cardboard reels (spools) of cardboard tape, wound on a rectangular mandrel with cheeks glued to the bobbin, consisting of a round turning table, with separate mechanisms fixed on it for processing operations, making at its full turn a stop on the number of said operations, characterized in that the device for putting the cheeks on the bobbin consists of a rectangular sleeve with spring surfaces entering the hole of the three rectangular frames and clamped into the hole There is a cardboard cheek between them, the whole device moving closer to the bobbin until the spring surfaces of the liner come into contact with it, which serve as guiding surfaces for sliding the frames together with the cardboard cheek from the liner to the bobbin.
