Labeling machine for labeling bottles Description

The invention relates to a labeling device for labeling bottles, with a labeling unit that has a pallet rotor arranged on a gear housing and with a label container carrier that is attached to the gear housing of the labeling unit radially away from the rotor in a horizontal plane pointing outwards and is provided with a cover plate below a label magazine.

Labeling devices of this type are known. A label magazine can be arranged on a label container carrier, which holds the labels to be stuck on bottles, for example, in the form of a horizontal stack. These labels are fed in a radial direction to the labeling unit, on which, among other things, a rotatably driven pallet rotor is arranged. The pallet rotor picks up the frontmost label from the stack of the label magazine, guides this label past a glue application station and then transfers it to a suitably fed bottle.

A wide variety of switching and operating elements are required to drive the rotor and the other components on the label unit. For example, air valves and electrical and pneumatic switching valves are required to be able to drive the unit accordingly.

In the state of the art, it was known that

The air valves or switching devices required to control and operate the labeling unit should be installed, for example, on the underside of the unit table top or in completely closed boxes. In both cases, access for assembly and repair work is extremely difficult. However, with labeling machines of this type in particular, maintenance or servicing of the device by the operating personnel must be possible in the shortest possible time so that the machine downtime, which is always necessary for maintenance work, can be reduced to a minimum.

It is therefore the object of the invention to provide a labeling device of the type mentioned above in which the control and switching devices required for the labeling unit can be easily maintained, but are nevertheless housed in a protected manner on the device.

This task is solved in a labeling device of the type mentioned above in that a container is arranged below the cover plate, which has two side winches, a base and an end wall on the side facing away from the gearbox housing and which is attached to the gearbox housing at the end facing the gearbox housing with two horizontal pivot bearing bolts and that the control and switching elements required for operating the unit are arranged in the container.

With these features, a container is first created below the cover plate of the label container carrier, which is open at the top but is covered by the cover plate in its closed position. All control and

■ Switching elements are completely protected. On the other hand, the

Containers can be folded down by swiveling around the swivel bearing bolts through a certain angle, so that the control and switching elements below the cover plate are essentially freely accessible. Repair and maintenance work can then be carried out very easily.

Nevertheless, the control and switching elements are optimally protected against contamination in the closed position.

In an advantageous development of the invention, the control and switching elements are attached to the bottom of the container. This means that the control and switching elements are also swung away when the container is swung away, so that free access to these elements is guaranteed at all times when the container is swung away.

A A further development of the innovation provides for the

The container is largely covered by a wall of the gearbox housing on the front side facing the gearbox housing when it is closed. This saves a front wall on the container on the side facing the gearbox housing because the container is then covered by the wall of the gearbox housing itself on this front side when it is closed thanks to a suitable arrangement.

A further advantageous embodiment provides that the pivot bearing bolts are inserted through a slot in the side walls

of the container are screwed to the gearbox housing. This is a simple way of pivoting the container on the gearbox housing, and the slot also allows the container to be moved to a certain extent, which makes it easier to align it with the locking devices on the opposite end face that hold the container in the closed position.

The design of the front wall of the container, which runs diagonally upwards from the bottom, enables a handle to be attached so that the container can be easily lifted and then locked, particularly for moving it into the closed position.

In order to be able to hold the container in the closed position, a further embodiment of the invention provides that the front wall of the container has a cover that, in the closed position, points approximately vertically upwards and extends beyond the side walls. The cover is provided with a slot for a clamping screw that is arranged in a support element of the cover plate. The slot has the width of the clamping screw, so that in the closed position the container with the slot comes between the head of the clamping screw and the support element. When the clamping screw is screwed in, it then presses the front wall of the container against the support element of the cover plate, whereby the container remains firmly in its closed position.

In order to seal the container completely dust-tight, the cover plate is provided with bevelled sealing strips that overlap the side walls in the closed position.

In order to connect the control and switching elements housed in the container to the corresponding feed and supply lines, openings are provided in the side walls of the container for the pneumatic and electrical feed and output lines as well as for a water line.

A further embodiment provides for an emergency stop switch to be arranged on one of the side walls.

Finally, in a further development, a stop is arranged in the swivel range of the container in the open position. The stop can be formed, for example, by an edge of the machine table on which the unit rests. This stop not only serves to limit the swivel range of the container, but also serves as a counter-hold if, for example, control devices have to be unscrewed from the container, whereby a certain amount of pressure has to be exerted on the bottom of the container. The container cannot then move away.

The invention is further explained and described below using the embodiment shown in the drawing.

The labeling device 1 comprises a labeling unit 3, only partially shown, in which a pallet rotor **, also only partially shown, is rotatably mounted on a gear housing 5. Radially towards the pallet rotor 4, in the peripheral area of the labeling unit, there is a label container carrier which projects essentially horizontally outwards and is designated as a whole by 2. In the example shown, this label container carrier carries a label magazine 6 in which a label stack 7 is housed. When the pallet rotor 4 rotates, the pallet shafts designed there take a label from the end of the label stack assigned to the labeling unit and convey it in a known manner past a glue application device onto the bottles to be labeled.

Below the label magazine 6, a cover plate 8 is arranged in the form of a thin-walled sheet metal on a cross member 9. This cover plate 8 has bent side strips 8a on both long sides that widen downwards.

A container 12 is arranged beneath the cover plate 8. The container 12 essentially consists of an end wall 13, the two parallel, identically designed side walls 14 and 15 and a base 16. On the side facing the gear housing 5, the side walls 14 and 15 and thus the container 12 are connected to the gear housing via pivot bearing bolts 18. The free ends of the side walls 14 and 15 overlap a wall of the gear housing 20 at the side, which in the closed position of the container shown in Figure 2 supports the container on its side facing the gear housing 5.

facing front side.

The container contains the components required to operate the 1st labelling unit required control and

K Switching elements, such as air valves, hydraulic Control valves and electrical switches are housed.

All of these parts are firmly attached to the bottom of the container. In order to be able to introduce the corresponding supply lines into the container, appropriate holes or openings are provided in the bottom and/or side walls of the container.

The pivot bearing pin 18 shown in Figure 1 and the pivot bearing pin provided on the other side wall, which is not shown in the drawing, form a horizontal pivot axis for the container 12, about which the container can be pivoted downwards or upwards.

On the front wall 13 of the container 12 there is a

; upwardly projecting aperture 13a. This aperture

is provided approximately in the middle with a slot 19 that runs downwards from the free edge. When the container is swiveled up, this slot 19 comes to lie between a clamping screw 11 provided on a support element 10 of the cover plate and the support element, so that by tightening the clamping screw 11 the container is held in its closed position because the screw 11 presses the cover 13a against the support element 10 below the cross member 9.

The container can be made of thin-walled sheet metal, or it can be a plastic container or made of • other suitable material. An emergency stop switch 22 is arranged on the filter line of the container.

Figure 2 shows the schematic side view of the container with solid lines in its closed position. It can be seen that in the closed position the side strips 8a overlap the side walls 15 of the container. In its closed position S the container is therefore completely covered by the cover plate 8 both from above and from the side and is thus reliably sealed against the ingress of dirt. As Figure 2 also shows, the pivot bearing bolts 18 can be inserted through elongated holes 23 in the side walls 14 and 15 of the container 12. This allows the container to be brought into a position when pivoted up so that the slot 19 can be inserted under the clamping screw 11.

In order to limit the swivel range of the container in the open position, stops (not shown in detail) can be attached. A stop can be formed, for example, by placing the container on the machine table 24 on which the entire device rests. This is indicated in Figure 2 at 25.

The front wall 13 of the container slopes downwards, as shown in particular in Figure 2. This makes it easy to attach a handle 21 without the handle protruding forwards beyond the contour of the container in a disruptive manner.

As Figure 1 clearly shows, in the folded-down position all control and switching elements housed in the container are easily accessible for maintenance and repair work. To do this, simply loosen the clamping screw 11 so that the container can then be folded down. To fold down the container, pull the

Handle 21 is held and slowly swung downwards. After completion of the repair* or hardening work, the container is returned to its closed position shown in Figure 2 and secured with the clamping screw 11. The cover plate & completely covers the container/ so that the control and switching elements housed in the container are reliably protected against the ingress of dust and dirt particles.

The arrangement of the container below the labeling container carrier 2 also offers the advantage that the control and switching elements are protected in an area that does not hinder accessibility, in particular to the labeling unit.

In cases where, for example, complete encapsulation of these elements 17 is not necessary due to the control and switching elements housed in the container being particularly resistant to dirt or due to a low level of dust and dirt at the installation location of the device, side walls or end walls on the container can be dispensed with entirely or at least partially.
