The pencils 4 on the conveyor 3 measure at such a distance from each other -be provided that this corresponds to that between the spindles 6 on the machine.

A carriage 7 is arranged so that it is at one end of all machines 1 passes, while the Trmmu of the belt conveyor 3 at right angles according to Fig. 2 crosses. On the carriage are two guide rails 9 at right angles to the direction of travel of the slide arranged. Two collectors 11 and 12 for full flasks are on the slide 7 mounted in an arrangement which is movable along the rails 9, i.e. a Movement parallel to the row of spindles 6 on the machine 1 is provided. on The reason for this movable arrangement of the collectors 11 and 12 for the full flasks The Sanunlers can easily remove the full flasks from a certain cannette collecting station or certain cannette collecting stations made will.

The carriage 7 is also provided with a feeder 13 for empty bobbins provided fixedly thereon in a position slightly different from the position of the collector 11 for the full flasks is removed.

The collector 11 for the full cans has two guide rollers 14 and 16, an endless belt 17 moving in the direction of arrows A and around the rollers 14 and 16 is running, a number of pick-up pins 18 which are attached to the belt 17 in the equidistant from each other, and a drive source (not shown) to drive the rollers 14 and 16 in an intermittent manner. According to Fig. 3 are a number of locating pins 18 on tape t7 in spaced-apart alignment Fastened across the belt width when looking out of the direction of travel of the slide 7 looks. From the drawing it is clear that the constructions of the @collectors 12 for full flasks are a mirror image of that of collector 11.

The receiving pins 18 described above and their related Portions are generally referred to as the storage portion 19 for full cannets.

This storage part 19 works with a transfer part 21 for full Flannets together, which is towards the storage part 19 and away from it on the slide 7 is movable.

The Tranefteil 21 has a movable base 22 on a horizontal screw or threaded spindle 23 is mounted by means of nuts 24 attached to the underside thereof. The threaded rod 23 extends in the direction of travel of the carriage 7 and is for rotation iit a reversible drive 26 connected via a suitable gear mechanism 27. When the threaded rod 23 is therefore rotated by the drive 26, the base 22 migrates in the direction on the memory part 19 on the slide top to and away from him.

Two support arms 36a and 36b are arranged radially on the horizontal shaft 34, and at their free ends they carry a pivot shaft 37 which extends parallel to the horizontal shaft 34 extends. This pivot shaft 37 is with a worm gear 38 provided that on a End of the same is attached and that to Rotation with a useteuerbaren drive 39 encoder a worm 4t and a shaft 42 is connected. The pivot shaft 37 also carries a number of grippers 43, the 4 fland conveyor at points directly above the upright pins 3 are stored. These grippers are used to grip the full cannets during the changing process.

Details of the empty bobbin feeder 13 are shown in Pig. 4 shown.

A number of empty bobbins 44 are in two containers 46, arranged side by side. The lower end of the container 46 is with a rotating bobbin dispenser 47 provided, which has a plurality of peripheral recesses 48 has, which receive the empty bobbins, which from the container 46 down fall. The rotating dispenser 497 is made intermittent by a suitable drive turned. A reel shaft 49 for delivering the empty reels is at the bottom of the rotating dispenser 47 is formed. The lower end of the shaft 49 is through a TQr 51 closed, which is opened at selected intervals. Therefore can the empty bobbin; which falls from the rotating dispenser 47, within the shaft 49 are held when EUr 51 is closed. A horizontal swivel shaft 52 is supported at both ends by two piston rods 53 in pressure cylinders 54, e.g. b-cylinders. Two swing arms 56 are each at one end thereof on the shaft 5? supported while they rotatably carry grippers 57 on the free inden. A swing the swing arm 56 is caused by a suitable drive (not shown), associated with it, The working strokes of the foregoing elements are carried out by Known limit switch mechanisms controlled at certain points in relation arranged on the movement paths of the elements and electrically connected to the drives of the elements for their actuation are connected.

The function of the device according to the invention is described below in individually described.

After completing the changing and placing operations on the Masc 1 gel @@ gt the carriage 7 in the position shown in FIGS. 1 and 2. In this egg State the belt conveyor 3 moves in such a way that the full canets 58 sitting on them come directly under the gripper 43 of the transfer part 21 for the full cans. Then the drive 31 begins its normal rotation to the gripper 43 in the direction to lower the full flasks 58 on the belt conveyor 3. After the grippers 43 Having grasped the heads of the full flasks 58, the drive 31 begins its reverse rotation to raise the grippers 43 so that the full flasks in reach the prescribed height.

The reversing drive 39 then rotates in such a way that the grippers 43 rotate 90 degrees around the axis of the pivot shaft 37, and the full flasks 58 are held horizontally, as indicated by the dash-dotted lines in Fig. 1 is shown.

In this state, the reversing drive 26 begins to rotate, and by the rotation of the threaded rod 23 caused thereby the base 22 and the overall construction of the tranfer part 21 for the full Cannettes, which is arranged thereon, the storage part 19 for full cannettes. By this approach of the transfer parts 21 are full flutes 58, which by the grippers 43 are placed over the pins 18 of the band 17. After completing this Placing the full cans 58 are released from the grip of the gripper 43, the Transfer part 21 returns to its starting position and the grippers take theirs Starting situation again. During the return of the transfer part 21 and rotation the gripper 43 moves the tape 17 by a unit pitch in the indicated by the arrow indicated direction so that the next empty pins 18 in the position arrive, in which the next full cans 58 can be received. Simultaneously the belt conveyors 3 move in such a way that the next following full cans> 8 get directly under the gripper 43.

By repeating the above steps, all will become full Canettes 58 on the belt conveyors 3 on the collectors 11 and 12 for full cans collected on slide 7. At this moment the wanders sleds such that the feeder 13 for empty bobbins in the position of the can holder 2 for the supply of empty bobbins 44 arrives.

Before the dobine feeder 13 arrives at this position, it becomes an empty one Bobine 44 in each shaft 49 by the rotation of the respective red-generating dispenser 47 and held there in support on the respective door 51 Time is closed. In this arrangement, the respective swing arm 56 operated to oscillate so that the gripper carried by it 57 grab the heads of the corresponding empty bobbins 44 that are in the shafts 49 seated. Simultaneously with the return oscillation of the rocking arm 56 opens the door 51, and the empty reel 44 thus gripped becomes vertically straight Ei belt conveyor 3 held above the corresponding empty pin 4. After that, the Pressure cylinder 54 set in function, so that the empty bobbin 44, which by the Gripper 57 has been grasped, is lowered over the elements 53, 52 and 56. As a result of this lowering movement, the empty bobbins 44 are on the belt conveyor via the pins 4 3 set and then released from the grip of the gripper 57. Then all take corresponding parts their starting position for the next feeding of the empty bobbins back on. After the feeding of the empty bobbins in relation to the belt conveyor is completed on one side of the machine, the slide moves on, like this that the feeder for empty bobbins comes into the position in which the belt conveyor is on the other side of the machine.

As can be seen from the above description, there is the inventive Procedure dus the following steps, which are roughly summarized as follows can be: (1) Raising the full canisters away from the belt conveyor onto the they are put on after the change process.

(2) Transferring the full rannettes raised in this way to the storage part in a horizontal arrangement.

(3) Prepare the storage part for the next full exposure Flasks.

(4) Arrangement of empty bobbins in readiness positions.

(5) Mutual alignment of the positions of the empty bobbins with the belt conveyor * (6) lowering the empty bobbins onto the banu conveyor.

To perform these steps automatically in a sequence, assigns the above first embodiment of the device according to the invention one Slide on on which two collectors for full cans and a feeder for empty ones Bobbins sit.

The second embodiment of the invention is described below in a seldom described on the basis of a device in which the collecting of full flasks and feeding the empty bobbins by a single integrated mechanism that sits on a sledge that travels in a way as described essentially in connection with the first embodiment has been.
