Description

Device for loading packaging machines with sweets.

The invention relates to a device for loading a packaging machine with pieces of confectionery, such as candies, chocolate bars, pralines or the like. It is known to have such parts run in a row one after the other to the packaging point and to provide an up and down lifting ram at the end of the feeder required for this, which moves the parts one after the other into the actual packaging unit and transfers them. Such devices operate very slowly because the infeed unit _for the further confectionery pieces can always occur only after return movement of the lifting ram into its initial position, the movement of the lifting ram is again dependent on the work of the Verpackunägaggregats. Another disadvantage of the known device is that the individual articles are not fed to the lifting ram with sufficient precision and are very easily damaged, which leads to incorrect packaging.

The object of the invention is to eliminate these shortcomings and to create a feeder for packaging machines, which with the most careful handling of the individual packages a high work performance enables. According to the invention, this is achieved by that between the feeder and the lifting ram there is a distributor with two inlets running transversely across them and a pusher is arranged on both sides of the feeder, the depth of each inlet being at least twice the length of the piece and a switching mechanism driving the distributor and the push rods is provided, which their movements with those of the Lifting ram is coordinated in such a way that the incoming pieces of confectionery alternate laterally to the left from the feed direction or conveyed to the right, pushed into the inlets of the distributor by the pusher up to the height of the lifting ram and then be brought onto the lifting ram from the side.

The inlet of the pieces is preferably through one piece length behind the inlet side of the distributor limited, which is appropriate to the size of the packaging Parts is adjustable. The distributor can expediently be formed from a plate sweeping over the lifting ram, which has two slits which run parallel to one another and which are open to the front and which form the two inlets. Both sides The pushers arranged on the feeder can expediently be equipped with a common drive.

The idea of the invention allows the most diverse implementation options to. One of them is shown in the accompanying drawings, namely show the

The device essentially consists of a machine table 1, a support plate or the like, in which an opening 2 for the up and down "in the rest position with the top the plate 1 comparing lifting ram 3 is provided. In front of the table 1, the one formed from the adjustable guide rails 4 ends Feed channel for the pieces of confectionery to be packaged a, b, c, d .... A belt (not shown), a slider or the like can be used as a feeder.

Just above the table top 1 through a distribution plate 5 having inlet ducts 6, 6 ^1, guided on a guide 7 transversely ist.-The drive of the distributor plate 5 is carried out via a switching unit 8, 9> 10 in the required working stroke of the machine. On both sides i of the feeder 4, push-in punches 11, 11 'are provided which are equipped with a common drive and which have the task of pushing the individual pieces of confectionery deep into the inlets 6, 6.

The advance of the pieces of confectionery entering the device a, b, c etc. is limited by a stop 12, which is in front of the Lifting ram 3 is arranged adjustable and from the distributor plate is painted over, in which for this purpose a recess 13 drawn in dashed lines is provided on the underside. Above the Distribution plate 5 is a known per se at the height of the lifting ram Brush shaft, a folding box or the like. After on the distribution plate A blank of wrapping material over the object to be wrapped is laid aside, the lifting ram can push the object together with the wrapping material blank through the folding shaft, whereupon it is then grasped by grippers 14 arranged above it.

Of course, the wrapping of the piece of confectionery can also be done take place at another point, so that the device according to the invention is only used to move the aligned pieces of confectionery carefully handed over to gripper ZU in order to then feed them individually to other processing stations. In the pictures is only the latter case is reproduced.

- 4 The operation of the facility is as follows

The pieces of confectionery to be packaged a, b, c .... run in the Feed line 4 after the work table 1. In Fig. 1, the distributor 5 is in a central position, with the rear end of the left infeed 6 'is the piece of confectionery a, and in the front Part of the inlet 6, the piece of confectionery b. The middle bar of the distribution plate 5 limits the supply of further pieces of confectionery. the Distribution plate 5 moves from the position shown in FIG. 1 into the Position according to FIG. 2, in which it may stand still. During this movement, the piece of confectionery a is placed on the lifting ram 3 pushed. The two pushers 11 and 11 'move forward, so that the part b reaches the end of the inlet 6. The push-in 11'- runs empty. The inlet 6 'is in front of the row of incoming ones Pieces of confectionery, so that the first piece in the row c can now reach the stop 12. It is thus pushed so far into the inlet 6 ″ that, after the return movement has taken place, the Pushers 11, 11 · and of the lifting ram 3, the distributor plate 5 is theirs Return to the left can take place. Right now is the arrangement in the position shown in FIG. The piece of confectionery a has already returned to its original position Lifting ram 3 delivered to the gripper jaws I4.

After a further work step, the position of the parts according to FIG. 4 is given. This is a middle position in which the piece of confectionery b in the inlet 6 is not yet completely above the lifting ram 3 and the piece of confectionery ν is not yet in front of the pusher 11 '. Only in the position according to FIG. 5 can the part c be ^{pushed into the end of the inlet 6 1} and the part d up to the stop 12 during the forward stroke of the pusher 11, 11 ′. While this is taking place, the lifting ram 3 lifts the part b into the gripper jaws I4. There is enough time to move back. Only when the position of the parts according to FIG. 6 is given does the distributor plate 5 switch over so that the piece of confectionery c reaches the lifting ram 3 and the part d in front of the pusher 11.

With the arrangement according to the invention it can be achieved, for example, that at an assumed packaging speed of 300 pieces / miö · the lower punch 3 and the pusher 11, 11 ^r 3OO strokes / min, while the distributor plate 5 ¹¹ ^ r 150 strokes / min, As a result of these different working speeds, a very long time is available for the articles to enter the distribution plate, namely the time in which the lower punch completes its upward and downward stroke guided exactly, so that their exact fitting support on the lower punch is guaranteed.
