The invention relates to a machine particularly suitable for packing sliced bread in polyethylene bags. By changing the machine in a minor nature they can be individually or for the packaging of other objects in groups also, as a number of rolls _t or even a plurality of individual articles, the ala group by a slider in the opening of a held-open suitably bag "use. be moved with such -this packaging machine, it is important that the slide fast" is moved and * always under control, so that will be the good or the items clean and tight packed during the packaging process, and in that the slide quickly and is reliably withdrawn from the bag in order to return to its original position & urüok and to be ready for further packaging operation.

The packaging machine shown in the drawings has an underframe 1 which supports a structure 2 which is attached to a Long side of a table over which the goods to be packed are guided to the packing station 4 »is arranged. The movement is through Slider 5 causes that sit at the ends of curved arms that are attached to support rods 7. Each of these poles will by a collar Θ, which is carried by a roller chain 9, and a second collar 10 arranged at a distance from the collar 8, which is carried by a roller chain 11, held as in Fig. 4 is shown. The roller chain 9 is via gears 12 and moved and held and guided by these, as in the Pig. 4 and θ au can be seen. The chain 11 is made up of gears 14 and £ 1. held at the opposite end of the orbit and

* The curvatures of the two chains 9 and 11 are due to the Gear wheels aligned in the same way. They result in an orbit around which the slide support rods 7 are moved. The gears 13 and 15 are rotatably supported by a common shaft 16.

The shaft 16 '/ which carries the gears 12 and 14 also carries a drive gear 17 for rotating the shaft, as shown in FIG. An intermediate shaft 18 carries a toothed wheel 19 which is connected to the toothed wheel 17 by a chain 20. A check gear chain λ 21 is engaged with the gear 22 mounted on the shaft 18, in connection to the shaft to be driven, the force applied to the chain 21 is driving the two slide carrier chains 9 and 11 at a rate that corresponds to the speed with which the objects are to be moved on the table 3 during the packaging process. The Kechaniciüua for the drive chain 21 can be controlled by suitable control means 21 'to bring about the starting and stopping movement of the slide support rods 7 around their orbit.

At the packaging station 4 a stack of bags 23, for example made of polyethylene material, is kept ready so that the open ends of the bags are opposite the objects that are moved to them along the table by the sliders 5 * The upper bag can be passed through a The air nozzle must be opened so that the ends of sprinkling fingers 24 can reach into the end of the bag.

packs, for example sliced bread can be. When the item to be packed is put through the slider into the bag, the smooth movement of the pusher move the filled bag away from the bag stack and push it onto an outlet 25, - ^ he slide carrier mechanism then pulls the slide off the opening of the bag and allows the slide to return along the orbit given by the chains 9 and 11, to pack another item.

Each slide 5 is carried by an arcuate arm 6,

which hangs down from its support rod 7 so that the support rod extends over the path of the object to be packed, and accordingly does not interfere with the movement of the object. ! The pusher support arm is backwards and upwards bent by the slide so that the slide during the Filling a substantial distance into the mouth of the bag goes forward without the curved arm obstructing the bag opening. . "· -.

The slide should be removed far enough from the support rod 7 so that the slide can be withdrawn from the opening of the bag by rotating the rod 7 about its axis, when the object is packed, and also the rod can still be moved in the same direction around the packed one Move the bag through the slider.

The position of the slide has been found to be desirable and steer his support arms 6 when he is in orbit moved, which is given by the chains 9 and 11. The position is by controlling the movement of the pusher arm support rods on her collar 8 and, JLO-reached. The rods are in the collar freely rotatable, but they are against longitudinal displacement relative to the collar by fixed collar 26, which on "the ^ rod 7 next to * the corresponding collar 8 and 10 sit, held.

Preferably, the slide 5 and their holding arms remain in the stand in the same position while their ■ 1-aItentang.en along the

upper and lower stretches of orbit are moved. The position of the slide can be determined by rotating the rods 7. and rotation may be the arms of a crank 2NC disposed on the rod 7 by controlling the pivoting movement can be achieved. As best in Pig. 4, the crank arm carries upper and lower blocks 30 at a fixed distance from each other and at a considerable distance from the axis of the shaft 7. The rollers ride on a straight guide rail 31 which runs along the upper and lower sections of the support rod orbit Ψ extends between the gears carrying the chains. Since the connection between each roller 30 and the rail 31 holds the crank arm 29 against pivoting movement, the slide support rod 7 is accordingly prevented from rotating and the slide 5 and its curved shaft 6 are held in a constant position.

At the two ends of the carrier rod circulation path, it is necessary to transfer the connection of the crank arm rollers 30 with one of the rails 31 to the connection with the other rail 31. For this purpose, the rollers and their crank arm on the side of the material feed must be lowered from the upper rail 31 to the lower rail 31. At the outlet end of the filled bags, the rollers 30 and their crank arms must be lifted from the lower rail 31 to the upper rail 31. In order to achieve a predetermined control of the position of the slide 5 and its support arms 6 at the ends of the round and to a random change of the position of the slider and of the arms during movement of the Trä _e; erotangen at the ends of the orbit to prevent, is a MechOtiiomus bulge, the duo swiveling the cranks 29 from the time where the

In order to control the pivoting of the crank 29 at each end of the orbit of the support bars 7 during the transition described above, unidirectional control means are provided at each end of the orbit of the bars. This tax means on | At the end of the orbit near the packaging station they have an arm 32 which is fastened to a stub shaft 33 which can be rotated via a gear 34, as can best be seen in FIGS. This toothed wheel is driven by a toothed wheel 35 which is connected to the toothed wheel 34 via a short chain on the part 16 which carries the toothed wheels 15 and 15. The distance between the axis of the shaft 16 and 33 corresponds to the distance between the axes of the slide support rod 7 and the axis of one of the rollers 30 on the crank arm 29, which has an axle pin 37 which is long enough to be connected to the arm 32 get. The end of the arm has a recess therein of a size and shape for engaging the axle bolt 37.

Rod 7 is described, but removed from it. The gears 34 and 35 and the chain 36 are timed such that
the received end of the arm 32 engages the roller axle pins 37 when the crank arm 9 is moved to the end of the orbit near the packing station, as shown in Pig. 4 is shown. In addition, the support rods 7 are along the chains and 11 at a distance that corresponds to one or more complete TJirr rotations of the arm 32, so that the excluded end
of the arm can come into position, do the end of the axle pin 37 of each crank yarn to receive when a Trsgerstan.re approaches the gears 13 and 15, as shown in Pig, 4 is shown.

At the outlet end of the filled bags of the orbit of the carrier bars 7 have the unidirectional rotatable control means to control the location of the slide 5 and its support arm the shape of a rotor 38, which has a group of guide rollers in a square 39 carries. These roles have a sufficient distance from each other, in order to grasp passages between them for receiving a wing carried by the crank arm 29. That wing advantageously has a double beveled end to facilitate its entry between the guide rollers 39 au. The rotor is rotatably mounted in a support block 41 attached to the end of the lower rail 31, as best shown in Pig. 8 to see is.

A spring loaded locking roller 42 mounted near the block 41 engages a recess in the periphery of the rotor 38 to hold the rotor in a position where one of the passages between the opposing rollers 39 is level with it the crank arm wing 40 is, while the rollers 30 of the crank arm are still in engagement with the lower rail 31.

As a result of this leverage of the wing 40, the rotor 38 is rotated through an angle of approximately 90 °, so that the locking roller 42 in at least a partial connection with a Another recess 43 is located, which is arranged offset by 90 on the periphery of the rotor 38. When the wing 40 of the With rollers 39 free, the locking roller 42 will come fully into engagement with a recess 43 to provide the rotor with another passage between the rollers 39 on the same tyb'he with a nearby one To bring wing 40 of another crank arm 29 into position.
