Abstract

The boxing machine comprises of modules (6) arranged along the conveyance path of the products for packaging. The modules include module tappets and folders for processing the products. The modules are arranged transversing the conveyance direction in which the carriages are moved from the folder and module tappet of one module to another. Separate curves (24,30) are used for controlling the movement of the carriages in conveyance direction. An independent claim is also included for the careful pushing of products into a packing container using circulating folder and module tappets.

Description

The The invention relates to a device for inserting products and / or brochures, if any, into a packaging container in a packaging machine, with one over a certain distance parallel to the products guided plug-in modules with a push-in plunger and / or a leaflet pre-insertion tongue which can be pre-positioned above the products and on the products is lowerable, wherein the insertion plunger and the leaflet pre-insertion tongue together perform a push-in movement introducing the products into the container.

Furthermore The invention relates to a method for gentle insertion of the products in the container by means of circulating brochure Vorschubschubzungen and / or Produktinschzustößeln, wherein the leaflet feed tongue and / or the product pushrod during its Circulating a product depth exceeding Make the stroke.

contraption and methods of the type mentioned are generally found to be continuous working packaging machines use, for example equipped with a product chain are on which the products to be packaged, such as tubes, bottles or stacks of blister pack strips. Parallel to the product chain, containers, such as folding cartons, guided, in which the products may be inserted together with a prospectus are. This is done with the help of Produktvoreinschubzungen and Slide tappets, the in the main conveying direction by means of a chain conveyor as well moved parallel to the product chain and for insertion a Exercise insertion movement perpendicular to their main conveying direction.

Device for simultaneous insertion of product and leaflet in boxes, wherein the transported in cells of the product transport chain product is transferred together with the leaflets in the also transported in cells of the carton transport chain boxes cell by cell, are known in packaging machines various embodiments and, for example in the DE 3 341 573 A1 , of the DE 101 48 249 A1 as well as the EP 0 995 684 B1 from which this application is based.

there it is essential that the movement of the various organs of work, d. H. the brochure pre-insertion tongue and the insertion plunger, exactly on the size of the products to be inserted and the boxes is tuned. If the cover tongue is too early on the Stack of packaging strips is deposited and on its top is moved under pressure, without the stack is supported laterally, can it happen that the upper packaging strip is moved, whereby the desired Stack shape is no longer exist and the stack is no longer in the Container inserted can be. About that In addition, at Increasing productivity Such machines are also in the horizontal direction when inserting the Product in the box elastic deformations of the blister pack occur that deform the product to the extent that it no longer safely in the box is inserted. Also, the upstream of the Machine located brochure feeder and / or the product feeder Error result, which are then sorted out of the stream ready packaged goods laboriously have to.

task The invention is therefore an apparatus and a method of the type mentioned, which increases the productivity of the machine qualitatively better deployment of the packaged finished product allows.

These The object is achieved in a generic device in that the slide assemblies two movable transversely to the transport direction guided Have carriage, preferably for the Prospektvoreinschub and one for the push-in plunger whose Movement is designed controlled by separate curves.

On that way each of the movements arbitrarily design by own cams, without that with the change a control cam and another cam is changed. Consequently the individual control processes can be influenced independently of each other.

In Embodiment of the invention it is provided that the control cam for the Product insertion between their extremes a region of lesser slope having. This area lets directly before retracting the working element into the carton arrange, so that the acceleration of the prospectus or the product for the Pushing into the box takes place almost bum-free. Will be mass forces advantageously avoided. The prospectus and the product learns in consequence the mass forces no deformations that could give rise to malfunctions.

In further advantageous embodiment of the device is provided that also the control curve for the leaflet feed has an area of lesser pitch. The susceptibility to interference the brochure Voreinschubes is reduced by this measure with advantage.

The subsequent sorting out of faulty products is facilitated if at least one of the control curves a turnout and at least one having alternative control curve. The switch may then be driven in response to appropriate sensors monitoring upstream for product accuracy. If, for example, one of the sensors upstream detects, for example, a missing leaflet, then the slide-in module can be controlled by operating the turnout so that no insertion process takes place and the products and / or brochures are removed. A subsequent quality control can be eliminated with advantage.

The Control of faulty products can also be done by means of the switch very high filling speeds done when the switch several successive switching actuators having. By successively switching actuators can even at high speeds of the withdrawable module, the switching time so extended be that no excessive forces through Shocks occur.

Also the lowering movement of the brochure Vorschubschub can advantageously independent of the other cams take place when for the lowering a vertical Control cam is provided, the fixed and transverse to the transport direction is arranged in the withdrawable module.

To For this purpose, the leaflet insert tongue is also formed vertically guided, in that the leaflet insertion tongue has a parallelogram guide and a scanning element scanning the vertical cam.

The Maintenance of the cartoning device is greatly facilitated if the cartoning device is arranged in the manner of a balcony in front of a machine frame. All drive elements are thus easily accessible and the various Cams can be easily exchanged in a format change.

The Process task is by a gentle process for insertion of products in a packaging container by means of circulating leaflet insertion tongues and / or product tappets, wherein the brochure insert tongue and / or the product insert plunger during its Circulate a product depth exceeding the product Accomplish stroke, thereby solved that at least one of the working bodies, i. H. the leaflet insert tongue and / or the product insert plunger, before Delayed insertion of the product and / or the prospectus subsequently is accelerated again for insertion of the product and / or the prospectus. The maximum possible Hub of the work organ also determines the maximum carton depth, into which the product can be inserted. This hub remains even with a smaller format. Become folding cartons filled with products of lesser depth, it comes with conventional cartoners to bumps, since the Organs are already working at high speed on the products Approach insertion. The inventive delay of Work organs before this point avoids such shocks and the Danger of deformations of the product. Such deformations as a result of the mass forces occurring during insertion can malfunctions lead that by the method according to the invention be avoided.

In Embodiment of the method is provided that in dependence a signal of suitable sensors of at least one of the working organs led an alternative way becomes. The upstream For example, missing sensors will report missing leaflets or insufficiently filled with products cells, so that in such cases by the controller a faulty filling of the carton guide the working organs are omitted on an alternative path and one latter quality control on such mistakes can be avoided.

The Invention is in a preferred embodiment with reference on a drawing by way of example, with further advantageous details the figures of the drawing can be seen.

Functionally same Parts are provided with the same reference numerals.

The Figures of the drawing show in detail:

1 : the front view of a cartoner,

2 a side view of a cartoner according to 2 .

In 1 , the front view of a cartoner, only a few essential parts are shown schematically. At the frame 1 of the cartoner are left and right two sprockets 2 . 3 shown to drive two chains 4 . 5 ( 2 ) serve, in turn, a variety of plug-in modules 6 Wear the chain in the direction of the arrow 7 revolve. Of the slide-in modules, only four are shown for the sake of clarity. The products and brochures become parallel to the moving plug-in modules 6 in the direction of the arrow 8th fed. The top product drawer assembly 6 pushes it in the direction of the arrow 8th supplied product in the also in the arrow direction 8th parallel folding cartons, while the sub-turner assembly 6 moves outside the product transport, in the drawing from right to left. The insertion of the products takes place in such a cartoner without rest, ie continuously without individual cycles.

In 2 the cartoner is shown as a side view. Clearly recognizable here are the parallel guided chains 4 and 5 and the plug-in modules attached thereto 6 , Altogether are at the parallel led chains 4 and 5 for example, seventeen such drawer assemblies 6 available. Particularly advantageous is the balcony-like on the frame 1 freely protruding structure of the drive unit 42 ,

In 3 is the structure of such a slide-in module 6 from the side view and in 4 shown in more detail as a plan. According to 3 is in a cartoner one in the main conveying direction 8th that is, folded carton transport chain running perpendicular to the plane of the drawing 9 provided next to a product transport chain 10 runs parallel. In the illustrated state is located on the carton transport chain 9 an erect, on the product transport chain 3 facing side of an open carton 11 , On the product transport chain 10 are products 12 provided in the form of four superimposed blister pack strips. Between the carton 11 and the products 12 is a brochure 13 arranged, together with the products 12 in the carton 11 should be inserted.

The plug-in module 6 includes a support element 14 , which connects the two spaced transport chains, in the main conveying direction 8th ( 8th ). With the support element 14 is a horizontal guide 15 for the first sled 16 provided, which the sheet metal tongue 17 for the brochure feed via a parallelogram guide 18 emotional. This parallelogram guide 18 sits down from the handlebars 19 and with these in four points of articulation 20 associated brochure feed 40 and sledges 16 together, leaving the metal tongue 17 parallelogram with the carriage 16 connected is. On the flyer 40 on which the metal tongue 17 is attached, there is a cam follower 21 that about scanning the vertical backdrop curve 22 firmly attached to the support element 14 is connected, the lowering movement of the tongue 17 generated. The first slide is over a leadership role 29 in contact with a control cam 24 , in the 5 is shown.

On another horizontal lead 25 is a longitudinally displaceable second carriage 26 who is looking towards the product transportation chain 10 extending push-in plunger 27 carries, at the front free end of a slide 28 is arranged. By moving the carriage 26 can the arm 27 and with him the slider 28 horizontally in the direction of the product 12 be moved. For the drive is the second carriage for this purpose with the leadership role 23 in contact with a horizontal cam 30 ( 5 ).

4 shows the plug-in module 6 according to 3 in supervision.

In 5 is a view of the cartoner according to 1 and 2 shown in FIG 5 only three exemplary plug-in modules 6 are shown. The leadership roles are clear 29 the slide-in modules 6 to recognize that in attachment to the control curve 30 for the second carriage. This second carriage controls the movement of the leaflet while the guide rollers 23 at the control curve 24 abuts that control the product feed. The control curve 30 runs forward from the left side in the retracted position until it steadily engages in a rest 31 From there, in turn, steadily up to the extreme front position 32 runs, then back again until it reaches the outermost inner position 33 on the right side of the roll 29 reached. Similarly, the cam runs 24 for the leadership roles 23 , Also the curve 24 has a rest 34 on. At the extreme front 34 change the leading sides of the curve 24 , In addition, there is an alternative control curve 24 ' , on the by a sensor, not shown, by means of switch 35 staggered guide rollers 23 ' issue. Another turnout 43 simultaneously controls guiding role in dependence of the mentioned sensor 29 ' in the direction of the alternative control curve 30 ' so then the leadership 29 ' takes a path corresponding to the dashed-dotted line. The switches 35 and 43 with cam 24 ' and 30 ' thus give way to staged leadership roles 23 ' and 24 ' before, so that the insertion process is omitted.

A view of a switch according to detail 6 in 5 is in 6 shown enlarged, with the front view in 7 and the side view in 8th and 9 is shown. In normal operation, the guide rollers 23 along the control curve 24 guided. As soon as an unillustrated sensor detects a faulty filling or defective starting material, the leading role becomes 23 through a first and second curve segment 36 . 37 in the alternative control curve 24 ' urged, what by the leadership 23 ' is indicated. The switching process is by two cylinders 38 allows its piston rod 39 the two curve segments 36 and 37 one after the other into the appropriate switching position. Due to the small roll spacing of about 5 inches at a performance of 500 fillings per minute is the modulation of a single leadership role 23 ' a very time-critical process. It is located during the switching process auszusteuernde leadership role 23 ' still in the area of the first curve segment 36 while the lead role 23 that the control curve 24 should go through, even in the area of the second curve segment 37 located. Only when the leadership 23 the area of the second curve segment 37 left behind, can the second curve segment 37 from the cylinder 38 via piston rod 39 be spent in the shift position, so that the lead role 23 ' the alternative control curve 24 ' can go through. The distance between the guide rollers is actually narrower than in the drawing 6 shown. The soft 43 for guide rollers 29 is analogous to the switch 35 built and works accordingly.

The following is an insertion cycle based on the 3 and 5 explained. In the in 3 shown withdrawn position is the brochure Vorschub 40 and the metal tongue attached to it 17 in a retracted position in which the roll 23 within the control curve 24 near the products 12 the opposite end is arranged and wherein the tongue 6 above the products 12 and withdrawn from these is arranged.

When passing through the packaging machine is first the product feed 40 along the horizontal guide 15 to the right, d. h in the direction of the product transport chain 10 shifted, which also the product feed 40 with the metal tongue 17 is shifted to the right and where the role 21 on the vertical guide curve 22 rolls along and the product feed 40 with the metal tongue 17 while above the products 12 holds. The product feed 40 is postponed until the metal tongue 17 above the products 12 is arranged. Upon further passage through the packaging machine or the responsible control curve, the leading role 23 in a rest 34 having portion of the cam 24 , where previously the cam follower 21 the slope 41 the scenery curve 22 left behind and the metal tongue 17 on the products 12 has lowered.

At the same time and parallel to the movement of the product feed-in 40 is also the insertion plunger 27 through the leadership 29 moved and with his slider 28 to the product 12 moved up to the area of rest 31 to delay briefly and to stop in front of the product, and then back towards the product 12 together with the resting tongue 12 almost bum-free the stack towards the carton transport chain 9 and in the opening of the carton 11 retract while the prospectus 13 with introduce. After the two working organs, ie the metal tongue 17 and the slider 28 their foremost position in the fields 32 and 34 the guide curves 30 and 24 have reached, they are in a correspondingly reverse manner, but now without rest, led back to its extreme rear position, first with the tongue 17 out of the carton and only then the slide 28 the inserted product leaves.

Before the plug-in modules carry out the filling of the folding box, the condition of the parallel product and the folding boxes as well as the leaflets are checked with suitable sensors for their regularity. If an error is detected, then by operating the switch described above 35 and 43 the relevant leadership role 23 and 29 in the position 23 ' respectively. 29 ' crowded and along the control curve 24 ' and 30 ' guided.

On this way it is possible the productivity Such cartoning continue to increase.
