wide * consisting of a rod-shaped plunger, which in the mentioned channel runs and outside of the guide nit a carrier chain Terbunden let, we lohe alternately gate and performs back-to-back movements.

As is known, the automatic feeding magazines for bars consist of a store for the bars and one Length guide in which the rod is introduced to by means of A pusher can be pushed into the machine tool.

In the case of the known feed magazines, the guide is not completely piloted, but has a longitudinal base for the step of the hill, old that of the Stöeeel connected to the hit chain 1st. This “slot there are inlass SU y jamming when processing τοη bars with a small diameter or a small cross-section.

In addition, the well-known Zuftthrungsmagasine can only difficult to adapt to the different types of machine tools, especially as regards the butt jointing phase of the initial part of the bar being removed must, as it usually has irregularities that were formed when the rod was cut. This is particularly evident when the machine tool has a Version with movable headstock 1st, in which the headstock received alternative movements with poeitlT controlled door movements and a spring controlled Fiüok movements carries out which Teder must be removed from the original position so that there remains for the feed magazine Plats.

On the carrier 1, the pipe profiles 6 are attached, which the Support slide 7. You slide 7 has a longitudinal extension Same as that of the rod sections 5 and their lower edge covers the adjacent edge of the rope 3. As shown in Fig. can be seen, this edge has recesses in which Enter the projections of the part 3 of the rod sections 5. In this way it is prevented that the rods 4 », even if they are very thin, slide into gaps which »Between the guide 5 and the chute 7 remain, and jamming during the operation of the feed unit» * i ** cause. Above the rod sole 7 there are knife-like arranged plates 10. The plates are along the Slide 7 distributed and arranged transversely to this.

The lower edge of the plates 10 runs parallel to the chute 7 and defines a gap or channel in which the Rods 4 can be stored side by side on the slide. The distance of the lower edge of the plate 10 of the rod sole can be adjusted depending on the diameter of the rods to be processed. For this purpose, each plate 10 is on the arm 11a an angle lever by means of the bolts 12, which engage in longitudinal slots of the plate 10, attached. The arm 11a runs above the relevant rod section 5 and then connects to the upper arm 11b of the angled lever, which is attached to the side of the carrier 1 with screw caps 13 is attached.

Part 3 of the guide let above flat and parallel to the Level of the Ruteche 7 auegebilden. Further let this part 3 Provided at the top with a length measurement which corresponds to the length measurement which is attached to each rod at the bottom is provided. When the rod assembly 5 close off part 3, there is a construction element between these elements the closed running channel 30 (Fig. 6) and, in the case of Rare entrainment of the machine tool, the rotation channel for the inserted rod 4 is formed. Preferably they have the grooves forming the channel have a semicircular cross-section.

As can be seen from FIG. 3, at least one frustoconical pin 31 extends downward from each rod section 5, the base of which is tangential to the guide groove of the rods on the opposite side of the slide 7. The pin 31 can be inserted into a seat 32 of the stationary part 3 the guide occur when the rod section 5 closes on the part 3. The pin 31 have due to your The oblique course has the task of conveying the rods 4 into the recess of the part 3, even when the rods are suffering are curved. Except for the pins 31 and the seats 32, the parts 3 and 5 of the guides are also old pins and corresponding seats (not shown) provided, which is why the rod sections 5 always during the sliding movement Closing and opening are guided with respect to the part. Xm Channel 30 runs the ram 33 for the rods, which, as German

- 8 - 309814/0360

lent the pig. 8 can be removed, consists of a rod part which is provided at the front with an elastic sleeve 53a, which can be pushed onto the end of a rod and thereby connected to it. To enable the rod guided by the machine tool to rotate without the plunger also rotates in the guide, the elastic sleeve is mounted in such a way that it can be rotated with respect to its own axis. in the rear end of the pusher the wing 33b is radially efeatigt, which (see Fig. 3) emerges from the guide and extends under the sand of the carriage 7, which lies above the part 3, and is secured to a block 33c, which is guided between a tubular profile 6 and the leg 3. The block 33p is also firmly connected to an annularly closed chain 34 which runs around the toothed wheels 35 and 36. From FIGS. 4 and I ₉ can be seen that the bath 35 is located in the vicinity of the rear end of the frame of the Zuführungemagazins and is mounted on a Yelle 37 that rotates in bearings in the frame. The wheel 36, which is located in the area of the front end or the exit end of the magazine, is mounted in an analogous manner. The part of the chain 34 to which the plunger 33 is connected runs parallel to the guide 3, 5, whereas the other part engages on the gearwheel 40 and is tensioned by the gearwheel 39. The gear 40 1st, like the Flg. 1 and 4 show loosely mounted on the output shaft 41 of a reduction gear 42, the input shaft of which is driven by the reversible motor via the belt 43. The reduction 42 and the motor

' In addition, the one provided with a supplement of stimulating material 46 can be moved on the shaft 41 Disk 45 Uft «> e £ tte * -ie4iaf *« fe.e4 * «~ 4d mounted. Appendix 46 is pressed by a spring 47 against the bath 40, which is inserted between disk 45 and a washer 48, which latter is supported on a shoulder formed by the locknut screwed onto the shaft 41. Normally the bath 40 is rotated by the shaft 41 via the attachment 46 taken away. However, when the chain 34 is stationary, the shim 46 can slip on the toothed wheel 40. On shaft 41 is Furthermore, the pinion 49 is attached, around which the chain 50, which is closed in the form of a ring on the gear 51, runs. The last mentioned Tame wheel runs loosely on shaft 37 and can be rotated by the electromagnetic clutch 52 mounted on the shaft 37.

If das.Zahnrad 51 is coupled to the shaft 37, so The latter is more freely rotatable than when the bath 51 is freely rotatable. This is because the transmission ratio between the gears 50, 51 is smaller than that between the gears 40, 35 When the electromagnetic clutch 52 is switched on, the supplement 46 slips on the bath 40 and the chain slowly runs off. It can be seen from the above that the plunger 33 rests on the rod 4 can exert a smooth and regular boost.

Near the exit of the magazine is the lead 3 * 5 as Fig. 1 shows, of a locking member for the in channel advancing rod prevails, which it on örund the

The blocking element consists of the lever 53 »of the paralyze the feed magazine is hinged on an axis running parallel to the rod. The lever is further on its pivot axis against the return action of a spring movable. As soon as the spring 54 expands when the rod 4 strikes against the lever 53, the latter actuates the microscope holder 55 «which excites the electromagnet 56 causes that lifts the lever out of its locked position for the rod. As soon as the upper end of the rod is over the Lever 55 has moved out, the electromagnet 56 is de-energized and the lever can slide again over the rod near the bottom. As can be seen from FIG. 1, a buffer 57 acts on the chain 34 and, actuated by electromagnet 58, the chain tensioned against the stop 59.

On the shaft 37, the gear 77 is also attached (Fig. 1, 4 and 5), which meshes with the gear 78, which is mounted on the shaft 79, which is rotatable in the frame of the magazine is stored. In addition, the gear 80 is attached to the shaft 79, which is connected to the gear 81 of a shaft combs the one! Dell of a cyclical Koatroll-
