With the feed device of the invention described below, sleeves, where the height is greater than the diameter, automatically fed to the tool will. The basic condition when retightening pre-drawn sleeves is that they always point in the same direction get to the tool, d. H. the bottom of the pods must always face the same direction

ίο lie. It is also essential that the automatic further processing of pre-drawn tubes the feeding device just as many sleeves can be brought in as the tool processes further so that the machine does is fully exploited. These conditions are described with the establishment according to the Invention fully fulfilled.

Fig. Ι shows a container α in the front view in section.

Fig. 2 shows this container in a side view in section.

In the container α are the sleeves b that have already been pulled forward. These pre-drawn sleeves b are caught by the rotating hooks c, which are set in a rotating movement in the direction of arrow e by the drive d , and taken in the position thus detected up to the highest point and delivered to the channel / here. The channel / merges into the pipe g . The sleeves are fed to the slide // through the tube g. The slider /; brings these sleeves in a horizontal or vertical direction in front of the tool (not shown).

So that the slide /; can return a sleeve with each working stroke, the corresponding number of sleeves must be fed to the slide h. This cannot be achieved by a rigid drive, the speed of which is adapted to the working strokes of the slide /; because not all hooks c grasp a sleeve and deliver it to channel f rigid drive empty after some time. The feeder with the hooks c must therefore lead a larger number of sleeves to the channel f than the slide h takes away. This is achieved by the device according to the invention as follows:

Fig. 3 shows the arrangement of the hooks tr on a larger scale.

Fig. 4 shows the side view of these hooks with the feed chute /. / 'Is the bolt on which hook c can rotate; k ¹ , k ² are two rollers attached to hook c. When the hook c with the sleeve b has reached the upper point, as shown in Fig. 3. so the rollers k ¹ , k ² strike against the projection / the channel f. Since the cross to which the hooks c are attached is moved further in the direction of rotation e , the rollers k ¹ , k ^{2 run} on the projection / the channel f , and the hook c therefore makes a corresponding rotary movement, whereby the tips of the hooks c off

the sleeve h, which in turn is held by the stripper m, are unscrewed. This gives the hook c the position shown at μ (Fig. 3) and can thus continue its direction of rotation unhindered. When the hooks c have run off the projection I of the channel /, the hooks c are retracted to the original position by the coil springs.

> o Are the Rohrg · and the channel / with sleeves filled and a hook comes c with a sleeve to the upper point, this sleeve is no longer in the gutter / in, so can not behind the striker in reach

«5 and thus remains hanging on the tip of this hook during the turning movement of the hook c and is taken back into the container again by the hook c, as shown at 0 (Fig. 3). It is thus achieved that the channel / is always full of sleeves, since the hooks c bring more sleeves than are removed by the slide Ji. The unnecessarily raised sleeves are when the hook c rotates

these are taken back into the container.

Claims (5)

Patent claims: I. A device for feeding sleeves, characterized in that hooks (c) are rotatably arranged on a rotating cross or other part so that these hooks are rotated out of the sleeve (i>) when the rollers (k ¹ , k ² ) run up against the projection Q) of the channel (/). 2. Device according to. Claim 1, characterized characterized in that the hooks (c) are on the fixed bolt (i), In order to achieve the corresponding deflection during the rotary movement, move in an elongated hole on the bolt (z). 3. Apparatus according to claim 1 and 2, characterized in that at the beginning of the channel (/) a scraper (in) sits, which in the channel (/) introduced sleeves (b) during the rotational movement of the hook (c) of the same strips off. 4. Apparatus according to claim 1 to 3, characterized in that the sleeves (&), if the channel (/) is filled, through the hooks (c) back into the Containers are taken back. 5. Apparatus according to claim 1 to 4, characterized in that the tips of those hooks (c) that do not "take back a sleeve" back into the container in the divided channel (/) slip past the sleeves sitting therein and so the result Loosen the sleeves that are easily stuck by dirt and push them forward so that with each stroke of the slide Qi) a sleeve must go into it. 1 sheet of drawings
