Insertion device for hard goods

0300A5 / 0A39

The invention relates to an insertion device for hard goods, preferably for bottles.

The packaging of hard goods, preferably bottles for the purposes of an end user happens in the usual way in that these hard goods are packed in a cardboard box, embedded on a flexible carrier. The flexible carrier has the task of storing the individual hardware, e.g. bottles |

separated
to store from each other / in an orderly manner in the box. Especially in the case of bottles and other fragile goods, packaging on a flexible carrier in the carton is essential; this flexible carrier is used not only for orderly storage but also for transport protection against vibrations or falls. Particularly high requirements are often placed on a packaging machine when packaging bottles: namely, the bottles must be stored on the flexible carrier in the box in such a way that the label on all bottles points in the same direction, in particular upwards. An additional difficulty in the packaging of labeled bottles is that the label was only glued to the bottles shortly before packaging and is therefore still easily displaceable. A packaging machine must accordingly place such labeled bottles on the carrier and in the packaging tray with care, but nevertheless with the desired orientation. The problem is very similar with the packaging of other consumer goods such as radios, tape recorders or cameras.

Here, too, it is always required that the object with a specific orientation placed in a flexible carrier holder which is then finally put in a cardboard box.

So far, this process has been done entirely by hand carried out. For this purpose, the hard goods were first inserted into the flexible carrier, which is usually made of foam Hand inserted. Here, as in the case of the bottles, for example, care had to be taken to ensure that the desired Orientation of the goods was observed. Since the flexible carrier, after picking up the goods, is often no longer self-supporting could be - the weight of a single full bottle of champagne is a good four pounds - now it had to be Carriers loaded by the goods are in turn placed in a box by hand. When lifting by machine and inserting it into a box would include the plastic support Security cracked or broken. Only after this packaging step has also been carried out manually can the carton is fed to the final packaging steps, i.e. folded, glued and finally labeled will. These last packaging steps can then be carried out by machine.

The invention is based on the object to insert the hard goods in the carrier and the insertion of the hard were 'also machine-filled carrier in the boxes%

This object is achieved according to the invention in that how |

is done in a second step also the% by machine with the hard goods-filled carrier in the Εηά- I

if packing box put in.

First of all, it will be described how, according to the invention, the Hardware can be placed individually in the carrier. As an an example

I for hard goods, the following description is limited to etiket-% benefited bottles. ! After the labeled bottles placed in a known per se Etikettlermaschine by ^ a per se known transfer device with handing over arms to the plate of the device according to the invention '' $ have been, these bottles are up to the plate of the ER £ inventive device by a receiving holder | pressed. This holder presses the bottle up against H

the corking down. The holder is rigidly connected to the plate via a frame arm. The movement .·; of the holder down to the plate is from ν

'ι a closing spring forced that on a locking bolt

030045 / 0A39 I.

attached mounting bracket presses down. The Schlleßbolzei is guided for this in a slide bearing of the frame arm. To The holder can be lifted off at the top using the locking bolt « by an actuating plunger. This actuating tappet is also guided by sliding bearings in the frame arm; the actuating plunger presses upwards against the locking bolt which the holder is attached. The movement of the actuating plunger is made possible by the bends in a curved strip causes the actuating tappet to run along with a tappet roller. The movement of the operating plunger upwards is thereby forced that the plate performs a translational movement together with the frame arm and the actuating plunger mounted therein, so that the plunger roller on the Curve bar runs along. Bends in the curve bar up or down then have a corresponding movement of the actuating tappet. An upward bend in the curve bar is therefore the locking bolt and thus also push the receiving holder upwards away from the plate and thus release the bottle; conversely, a bending of the curved strip downwards will move the receiving holder let go down, which is already brought about by the closing spring, so that the bottle standing on the plate is firmly pressed by the holder. The so with a predetermined orientation of the label on the plate clamped bottle can by a tilting movement around the Tilt axis of the plate and the holder connected to it via the frame square into the horizontal

030045/0439

to be turned around. So the bottle comes with the given label orientation to float above the carrier on the transport chain.

According to the invention, the just described holding and tilting device for the bottle is rigidly connected to the transport chain. This way, synchronization between the carrier for the bottle and the holding and tilting device just described is guaranteed. The tilting movement is effected by a curved rail; The rocker arm, which is rigidly connected to the plate and thus also to the receiving holder guided by the frame arm, runs in this curved rail with a lever roller. An upward bend in the curved rail causes the bottle to pivot horizontally during the translation of the transport chain. Conversely, a downward bending of the curved rail during the translation of the transport chain, on which the holding and tilting device for the bottle is attached, causes the bottle to rotate vertically. The bends in the curve rail and the curve bar to pivot from and release the bottle must of course be coordinated so that first the bottle is pivoted horizontally and then released from the holder so that the bottle in the carrier on the Ti. -asport chain can fall into it freely.

030045/0439

The tilting axis is expediently opposite to the running direction slightly twisted in the transport chain, preferably by 3, so that the bottle with < the bottle already lying next to it does not come into contact; this becomes absolute ensured that the still moist and therefore movable The label on the bottle remains unchanged.

Advantageously, not only the receiving holder is movably supported in the frame arm, but also the plate. To do this, the plate is attached to a plate bolt that is guided by a plain bearing. The plate pin is hollow so that it can accommodate a plate spring which presses the plate pin and thus the plate upwards. The movement of the plate takes place at the same time as that of the holder, but in opposite directions; for this purpose, the movement of the actuating plunger is transmitted in the opposite direction to the plate pin via an opening lever, which in turn pushes the plate down exactly when the receiving holder on the locking pin is pushed up by the actuating plunger. In this way it can be achieved that the bottle is almost completely suddenly released to fall, especially when it is lying horizontally above the carrier on the transport chain . In order to control and secure the entire insertion process, a sensor that signals that the bottle is being held can also expediently be fitted in the receiving holder.

030045 / -0439

Of course, the kinematic reversal of the entire insertion process just described imaginable. That means that a bottle lying in a carrier was made by the Holding and tilting device is removed and brought into the vertical position.

Instead of the locking bolt for the Aufnahrsehhalter and the Pneumatically operated cylinders can also be used for the plate bolt for the plate. The tilting movement also occurs, in the example of the invention described above by the curved rail over the lever roller on the rocker arm is transmitted by a pneumatic device known per se.

The complete filling of a carrier, which of course can only hold a finite number of bottles, preferably 6 of them, is expediently not carried out all at once, but rather by placing the individual bottles one after the other in the carrier. For this purpose, in the event that the carrier can hold 6 bottles, 3 bottles are transported on both sides of the device according to the invention offset from one another on the transport chain. In a first filling step, two bottles, which are offset from one another but are still opposite, are tipped into the carrier.

030045/0439

Vorte ί lh.3 f te "* ^··:? Re, the bottles are thereby prevented d ^ ran to touch each other, the tilting axes di3 to d ° r Laufrichturg the conveyor chain can be easily rotated, preferably about 3 uti Thereafter. The two following bottles opposite one another and finally the two remaining bottles opposite one another are tipped into the carrier. Now that the carrier has been so completely filled with bottles, they can be put into a rigid box, because the carrier is burdened by the heavy bottles otherwise it would tear or break immediately in transit.

The second carried out by the device according to the invention The work step is now to put the carrier filled with the bottles into a rigid box. In addition the carrier filled with the bottles runs to the end of the transport chain; the transport chain runs at this end via the pulley of the transport chain. If this were part of the transport chain via the pulley of the transport chain, so the carriers filled with the bottles would fall down. This is why the device according to the invention is located in front of the transport chain, which runs over the pulley of the transport chain, a slope runs; those on the The transport chain of support pins guided by the movement of the transport chain is pushed onto the drainage slope. So-called back slides are attached at the end of these run-off bevels; these baking slides are preferably made

030045/0439

made of elastic spring steel strips; as a result, they are able to give way to a deflection of the carrier loaded by the bottles and at the same time adapt to it in such a way that the loaded carrier is supported. Synchronously with the drainage of the carrier loaded with the bottles on the drainage slope, a box is conveyed from below under the baking pusher and the drainage slope on a discharge belt. The carrier can now slide into the upper corner of this box. This sliding movement can be supported by a holding bump in the box, which internally engages in a corresponding recess in the carrier and thus pulls the carrier down from the drainage slope and the back slides. In this way, the carrier is finally drawn completely into the box and set down. The box filled with a carrier is then transported on the discharge belt so that the final cartoning can take place. The synchronization of the carrier on the carrier ^ nsportkette with the cartons at the discharge belt must be secured on the one hand by the fact that be effected in the same clock with the incoming to the deflection roller of the conveyor chain carriers boxes on the Abfurhband, and secondly the pre feed rates of the conveyor chain and the discharge belt are equal to each other. The synchronization of the transport chain with the discharge belt can be enforced by a kinematically rigid propellant. As a kinematically rigid propellant, a chain can be used, for example, which is connected to the pulleys of the transport chain and the discharge belt with toothed

030045/0439

wheels running. However, conventional gear drives or linkages between the steering roller, which are known per se, are also conceivable the transport chain and the pulley of the discharge belt. However, a synchronization of the transports is also conceivable by stepping motors connected in parallel. Between the individual carriers on the transport chain are expediently Empty spaces set up. These spaces correspond to spaces between the individual boxes on the discharge conveyor; these gaps between these boxes on the discharge belt should allow the free movement of one over the pulley of the discharge belt under the back slides or the drainage slope to secure incoming boxes. The shafts too are held on the discharge belt by holding pins in the conveying movement. Die3 is a technique known per se.

Instead of the slope, there is also a small moving rubber conveyor belt conceivable. This small, moving rubber conveyor belt must also be synchronized with the transport chain and the discharge belt be.

An embodiment of the device according to the invention is shown in the following drawings. These drawings are described in more detail below.

The pressure is generated by a closing spring (2o) against the locking bolt (3), which is connected to the holder is firmly connected. Receptacle holder and Locking bolts are guided in slide bearings in the frame arm (1). Inside the frame arm (1) The actuating tappet (2) also runs and is stored. If the actuating plunger (2) presses against the locking bolt (3) of the holder (4), so the bottle (16) is on the plate (6) Approved. The movement of the actuating ram

(2) is during the translational movement of the transport chain (12) with which the frame arm (1) over the tilt axis (15) is connected, controlled by the curve bar (9). On this curve bar (9) the actuating tappet (2) runs along with its tappet roller (11). The curve bar bends (9) upwards, it presses the actuating plunger (2) against the locking bolt accordingly

(3) and thus the holder (4) upwards. However, if the curved bar (9) bends down, the holder (4) is pressed down against the bottle by the closing spring (2o) via the locking bolt (3). The tilting movement of the frame (1) and the plate (6) about the tilt axis (15) is controlled by the curved rail (8).

The opening lever (19) is shown as a particularly expedient embodiment; this opening lever (19) cannot be seen in FIG. When the actuating plunger (2) is pushed upwards by the cam ledge (9), the opening lever (19) pushes the plate pin (18) on which the plate (6) is attached

below. At the same time, as already described in FIG. 1, the actuating plunger presses the receiving holder (4) over the locking bolt (3) upwards. Correspondingly like the receiving holder (4) from an I. Closing spring (2o) is pressed down over the locking bolt (3), the plate (6) is in the hollow plate bolt (18) pressed upwards by a plate spring (21). This holding and tilting device is firmly connected to the transport chain (12) on the mounting plate (13). Of course this connection is limited to a single link in the transport chain (12). The sensor (5) in the holder (4) is used to control and secure the bottle transport.

known way the bottles with oriented label from a labeling machine or a Hand over nudge table. For this purpose, the lower bottle tilt holders are offset by about the width of a bottle (25); The bottles are also pre-oriented from the lower transfer arms (26) to these lower bottle tilting holders (25) Hand over label. The transport chain (12) conveys the carrier (24) from right to left; included the first two bottles are first tipped into the carrier (24). In this process it turns out it is advantageous that the tilting axis (15) in relation to the direction of travel of the transport chain (12) is slightly twisted; the rotation of the tilting axes of the individual bottle tilting holders is like this chosen that always two bottles opposite one another and to be inserted into the carrier at the same time be kept a little further apart than their final position in the carrier is equivalent to. This prevents the still damp and therefore movable label one bottle cannot be touched and shifted by the neighboring bottle. After finally one after the other all bottles were placed in the carrier βΐηα ^ οπιπΐ the weighted down with the bottles Carrier at the end of the transport chain on the pulley of the transport chain.

030045/0439

This is shown in FIG.

FIG. 4 da3 an inclined run-off (27) is arranged in front of the guide pulley of the transport chain '(29). At the end of the run-up bevel, a back slide (28) is drawn, which advantageously consists of a spring steel strip. The carrier (24a) still on the transport chain (12) and filled with the bottles is pushed onto the drainage slope (27). The sliding movement is supported by the holding pins (14) on the receiving plates (13) of the transport chain (12). A void (33) is located between a carrier on the transport chain (24a) and a carrier on the run-off slope (24b). This empty space (33) corresponds to a space between the boxes on the discharge belt (35) A box is conveyed from below under the discharge bevel (27) and the baking slide (28) on the thorn discharge belt (35) under the discharge bevel (32a). The synchronization between the box under the drainage slope (32a) and the carrier on the drainage slope (24b) is ensured by a kinematically rigid propellant (31). If the carrier on the drainage slope (24b) does not slide by itself over the baking slide (28) into the box under the drainage slope (32a), the 030045/0439

Support on the drainage slope (24b) are supported by elnea holding bump (34) in the box under the drainage slope (32a), which engages in a corresponding recess in the carrier on the drainage slope (24b). However, it is also conceivable that instead of the run-off slope (27) a small moving conveyor belt made of rubber that is synchronized with the transport chain (12) and the discharge belt (35) is arranged. After the carrier on the drain incline (24b) has completely slipped or pulled or conveyed into the box under the drain incline (32a) , the filled box is conveyed in a known manner on the discharge belt (35) to the final cartoning. This is shown in the drawing by the box on the discharge belt (32b) with the carrier placed in it

The drainage incline (27) with the baking slide (28) are among the most important parts of the device according to the invention, as only prevented by them can be that the carrier with the bottles during the transfer from the transport chain (12) into the The box on the discharge belt (35) breaks or tears. Since the carrier is adapted to the shape of the bottle, when the carrier is inserted into the box a reorientation of the bottles 030045/0439

with the labels prevented. This ensures that it is finally in the box on the discharge belt (32b) the bottles in the carrier on the discharge belt (24c) all in the desired manner Way with the labels oriented. This is a special requirement of the customer, Be careful with all bottles with labels facing up.

The advantages achieved by the invention are that it is possible with it to be able to carry out the packaging of bottles or hard goods fully by machine. With bottles in particular, this means considerable progress, as the wage cost share is particularly pronounced here due to the packaging by hand. It should also be noted that now that all operations from filling a bottle bisjhin for labeling can be done by machine already in anrieh known queen bees, now up to the cartoning any further steps can be fully carried out by machine using the inventive device. Since cartoning can also be done automatically, this means that it is now possible to fill and pack bottles or hard goods automatically without any manual intervention. This is a major step forward, especially in the case of filling systems with the highest capacities, since these large capacities are now used or fully utilized without hindrance
