Description

Method and apparatus for removal

of parts adhering to vessels or containers

The invention relates to a method for removing or at least scribing adhering to vessels or containers parts, in particular labels, in which one or more substantially rotationally symmetrical or at least partially having a round cross-section elongated vessels or containers, in particular glass or plastic bottles, on a conveyor standing and moved substantially perpendicular to a longitudinal axis along a feed direction and thereby rotated at least in a portion each about the longitudinal axis, wherein during rotation with at least one tool, the parts removed from the vessels or containers or at least scored.

Furthermore, the invention relates to a device for removing or at least scribing adhering to vessels or containers parts, in particular labels, comprising at least one conveying means for moving one or more substantially rotationally symmetrical or at least partially having a circular cross-section having standing elongated vessels or containers, in particular glass - or plastic bottles, along a feed direction perpendicular to a longitudinal axis of the vessels or containers, and at least one means by which the vessels or containers in at least one section in each case about the longitudinal axis in rotational movement are displaceable, and at least one tool, the parts in the section removed or at least scratched. Glass or plastic bottles are returned to a bottler after use and processed there for reuse. For this, the bottles must be freed of all adhering parts, cleaned and checked for damage. In this case, different bottle sizes and shapes must be recognized and the respective devices for removing adhering parts adjusted accordingly. The adhering parts are made of different materials, such as

Plastic, metal or paper, and are attached with different adhesives or mechanically form-fitting, such as screw caps or capsules attached. According to the prior art, various devices of the type mentioned above are known. In US 5,718,030 A a device for removing labels from bottles is disclosed in which the bottles are guided in a continuous process on a conveyor along a circular path through a cleaning device. By rolling the bottles on a lateral guide surface, the bottles are set in rotation and cleaned by a wire brush located in the center of the cleaning device, which simultaneously adjusts the bottles to the guide surface. In this device is disadvantageous that only a small torque can be exerted on the bottles by a rotatable bottle holder and the guide surface and thus no permanent rotation of the bottles is guaranteed. Since a permanent rotation of the bottles but is required to achieve a relative speed between the outer bottle surface and wire brush, the achievable cleaning performance of the device must be considered as rather low. US 4,122,734 A discloses a device for removing labels from individual bottles, in which a bottle in the device is set in rotation and a laterally acting, spring-loaded cutting device is moved from top to bottom to detach a label. A major disadvantage is this

Device to be seen in the fact that this can only operate discontinuously and only one bottle in the device can be processed. An automated promotion of

Bottles in or out of the device is not provided so that only a low bottle throughput is achievable and the method described is considered cumbersome. In the documents DE 24 57 919 A1, US 4,715,920 A, DE 35 04 303 A1,

DE 39 02 324 A1, US Pat. No. 2,170,044 A and US Pat. No. 4,013,497 A disclose further devices for removing labels or closures from bottles. These use different conveyor and Abkratzvorrichtungen, but with different

Disadvantages. For example, it appears to be impossible for some devices to completely detach labels; some of the described processes work discontinuously, so that only a low bottle throughput is achievable; many of the disclosed devices appear difficult or impossible to adjust to different bottle sizes and shapes; in some of the described Process, it seems inevitable that bottles should be removed during cleaning or

Scratching of labels will be damaged.

The object of the invention is to eliminate these disadvantages or at least to

Reduce. In particular, the invention has for its object to provide a method of the type mentioned in the vessels or containers can be fully processed or cleaned, with a continuous conveying and

Editing the vessels or containers should be guaranteed. Another object of the invention is to provide a device of the type mentioned, with which a method described above is executable.

The first object is achieved in that in a method of the type mentioned, the vessels or containers in the at least one section are set in rotary motion by these positioned with a first, above the conveyor

Guide element are brought to rest on a second, opposite guide element, wherein the guide elements with a different

Speed can be moved relative to each other, wherein one of the guide elements can stand still, and the at least one tool above one of

Guide elements engages the vessels or containers.

An advantage achieved by the invention is to be seen in particular in that by the rotational movement of the vessels or containers, the at least one tool can fully engage with these or process them. It is simultaneously possible to convey and rotate the vessels; a continuous conveying and processing of the vessels is thus ensured and there is no interruption of the transport movement of the vessels. Furthermore, the lateral guide elements hold the vessels hold and the vessels or containers are thereby supported against the attached tools. Thus, the tools can engage the bottles with a required force without tilting them. By the method according to the invention, among other things, labels, banderoles, capsules and closures of bottles can be removed, whereby it finds application, for example, in the reuse of glass bottles. In this case, a damage-free cleaning of bottles is possible. Preferably, the vessels or containers are continuously moved in the section.

Conveyors and tools work continuously and simultaneously, which means that the process can be integrated into a continuous conveying system. The vessels are thus freed of adhering parts during their transport movement. This ensures an effective method which allows a high throughput of vessels or containers to be cleaned.

Conveniently, several vessels or containers are moved one behind the other. It can then process one and the same tool at the same time several vessels or containers and remove adhering parts, as the vessels or containers are conveyed past the tool. Thus, a feed speed can be increased and thereby many vessels or containers can be processed per time.

It has been proven that a flat, preferably straight conveyor belt is used as a conveyor. Thus, a feeding of the vessels or containers to the tools is possible in a simple and proven way. If local conditions so require, the conveyor belt can also be curved.

It is advantageous if a circulating belt or a stationary guide plate is used as the first guide element. Above all, the guide plate, which generates a corresponding friction to the vessels and therefore can also be referred to as a friction block, corresponds to a simple realization of the first

Guide element, is inexpensive and low maintenance. Preferably, a circulating belt is used as a second guide element. Such a guide element is easily driven, adjustable in its speed and proves itself for a simple technical implementation.

In order to achieve a rotation of the vessels or containers by simple technical means and with a simple control, the second guide element can be moved faster than the first guide element. In this way, the inventive method can be realized inexpensively. It has been proven that the first guide element in plan view parallel to

Feed direction held and the second guide element perpendicular thereto

is held displaceable. This can be done to adapt to different vessel or container sizes. In particular, by a spring-mounted storage of the second guide element such an adjustment automatically and independently, d. H. without adjustment motor and control.

It is advantageous if the second guide element and / or the at least one tool is moved perpendicular to the feed direction in response to a signal of a sensor on or in front of the at least one section in plan view in order to press the vessels or containers to the first guide element or to make the at least one tool to the vessels or containers accordingly. This allows the process to be automatically tuned to different vessel or container sizes and shapes.

Expediently, the parts are removed or at least scribed with at least one rotating cutting roller with one or more circumferentially arranged knives or an oscillatingly moved beam with one or more knives. With the method adhering closures, banderoles, labels and capsules can be removed or their surface are at least scratched so that this

adhering parts are easier to remove in a subsequent washing process.

Both cutting roller and beam can be made correspondingly long and edit at a position parallel to the feed direction a plurality of vessels simultaneously. By simultaneously rotating the vessels becomes an effective,

Complete removal of adhering parts at high feed rate and thus achieved a large vessel throughput.

Preferably, the knife or knives are protrusively attached to the cutting roll or the beam, wherein a base body of the cutting roll or the beam does not touch the vessels or containers. The main body of the cutting roller also has the function, the

Keep vessels at a minimum distance from the knives so that the jars can not tip into the cutting drum, which would block the system. It is advantageous if the knife or the knife are resiliently mounted. As a result, cutting forces can be limited and contour tracking of a cut is better possible, ie, the cutting roller can adapt to vessel contours. This is particularly advantageous for fracture-sensitive vessels.

It has been proven that in a first section, a first tool engages, wherein on a head of the vessel or container adhering parts are removed, and engages in a second section, a second tool, which is arranged at a different height than the first tool. In this case, the first section may be arranged before or after the second section. In the case of commercial bottles, such a method is advantageous, since labels and the like are usually applied in two areas, namely in the area of a bottle neck and in the area of a bottle belly.

Conveniently, a rotating cutting roller engage with the circumference

arranged knives as a first tool and a rotating brush roller as a second tool, wherein the cutting roller and the brush roller on

are arranged opposite sides of the conveyor and preferably rotate in each case towards the conveyor. The use of two different tools ensures effective removal of a wide variety of adhering parts, such as closures, banderoles, capsules and adhesive labels. Next

Cutting roller and brush roller is also an embodiment with cutting needles, cutting tips and knife blades conceivable. A combination of cutting, brushing and scratching methods gives an overall effective method. Preferably, the vessels or containers with the funding with a

Speed of 0.01 to 10.0 m / s moves. This range of speeds is a good compromise between high throughput of vessels and the most thorough removal of adherent parts. It is advantageous if a capsule or screwed lid of the vessel or container is attached to the capsule or lid by employing a friction device simultaneous forward movement of the vessel or container is released. Thus, in the same operation with a removal of labels and the like also a removal of screw caps and capsules in a technically simple and effective way possible.

The second object of the invention is achieved in that in a device of the type mentioned above, a first, positioned above the conveyor

Guiding element is provided, with which the vessels or containers in at least one portion for abutment with a second, opposite guide element can be brought, wherein the guide elements are movable relative to each other at a different speed, so that the vessels or containers are set in rotational movement, and that at least a tool is positioned for engagement above one of the guide members on the vessels or containers.

By rotating the vessels or containers, the tools can process the vessels over their entire circumference. Turning and conveying the vessels take place simultaneously, whereby a continuous processing of the vessels without interrupting their transport movement is possible. The guide elements support the vessels against cutting forces exerted laterally by the tools, in particular rotating tools, on the vessels, and the conveying means against downward cutting forces. This makes it possible for the tools to be applied to the vessels with adequate force without the vessels tilting. The inventive

Device is particularly suitable for removing closures, capsules, banderoles and labels of glass and plastic bottles during a continuous

Cleaning process, wherein adhering parts can be removed at almost any point of the vessel or at least be scratched. The device can open

automatic transfer lines for reuse of glass bottles or as a single device can be used.

The vessels or containers are preferably continuously movable in the section. By simultaneously conveying or transporting the vessels and their cleaning of adhering parts, the device can be integrated into a continuous conveying system. A high throughput of vessels or containers is thus ensured. Conveniently, the conveyor is a flat, preferably straight conveyor belt. A feeding of the vessels or containers to the at least one tool is carried out in a technically simple and proven way. In order to realize the first guide element in an effective and technically simple manner, a circulating belt or a guide plate can be provided as the first guide element.

It has been proven that a circumferential band is provided as a second guide element. Such a band is easy to drive and adjustable in its speed.

It is advantageous if the first guide element in plan view parallel to

Feed direction is aligned and the second guide member is mounted to be displaceable perpendicular thereto. This makes it easy to customize

different container sizes and shapes take place. In particular, by a resilient mounting of the second guide element such an adjustment is automatically enabled. Appropriately, a sensor for detecting a dimension of the vessels or containers is provided, wherein the sensor is in communication with a drive means, the second guide element and / or the at least one tool in response to a sensor signal in plan view perpendicular to the feed direction to the first

Guide member towards or away from this or to the vessels or away from them. Thus, with the device vessels or containers of different sizes and / or shapes can be treated.

Preferably, at least one tool is height-adjustable and / or horizontally and adjustably mounted normal to the feed direction. By such adjustable storage means suspension and guiding devices can be freed of adhering parts with the tools different vessel and / or container shapes, a departure complex geometries through the tool and an adaptation to new vessel contours is easily possible. In addition, sweeping an altitude range can process a wide range of vessels. It has been proven that at least one tool is designed as a rotating cutting roller with one or more circumferentially arranged knives or as an oscillatingly moved beam with one or more knives. Because both

Cutting roller and beams can be performed long and aligned parallel to the feed direction, a simultaneous processing of many vessels or containers is possible. Together with the possibility of a continuous process in which adhering parts are removed or scratched by the moving vessels, without stopping the movement of the vessels or the conveyor and without damaging the bottles, a high feed rate and thus a high Bottle throughput can be achieved with a high cleaning performance.

It is advantageous if the knife or the knife are protrusively attached to the cutting roller or the beam. Thus, a rapid and effective removal of adhering parts is possible.

Conveniently, the blades are resiliently mounted. This allows the

Cutting roller and / or the oscillating moving beam adjust the vessel contours, whereby damage to the vessels is prevented in this process. In the course of bottle reuse the process can be carried out again and again.

In order to be able to process two areas on bottles, labels or the like, such as the area of a bottle neck and the area of a bottle belly, with which at least one tool can be processed, a first tool can be provided in a first section and a second tool can be provided in a second section be with the second tool is arranged at a different height than the first

Tool.

It is advantageous if a rotating cutting roller with peripherally arranged knives are provided as the first tool in the first section and a rotating brush roller arranged in the second section as a second tool, wherein the cutting roller and the brush roller are arranged on opposite sides of the conveying means and preferably for each Conveyor towards are rotatable. As an alternative to knives and brushes cutting needles can be arranged on a roller. By using different types of tools can be done by cutting, brushing and / or scoring an effective removal of various adhering to the vessels or containers parts, such as closures, capsules, bands and

Adhesive labels can be achieved. It has been proven that a preferably height-adjustable over the conveyor friction device is provided, with which a capsule or a screwed lid of the vessel or container by hiring the capsule or lid with simultaneous forward movement of the vessel or container is solvable. By a simple technical device can so - even under utilization of the

Rotational movement of the vessels - Unscrew caps and capsules from the vessels or containers in the same operation by removing labels.

Further features, advantages and effects of the invention will become apparent from the embodiment illustrated below. The drawings, to which reference is made, show:

Fig. 7 is a schematic bottom view of a device according to FIG. 5 along the section Vll-VII.

In Fig. 1 is a schematic plan view of an inventive device 1 for removing or at least scribe adhering to glass or plastic bottles 2 parts, in particular labels 3, 3 ', is shown. The device 1 comprises a flat, rectilinear conveyor belt 5, which the glass or plastic bottles 2 the Purification process feeds. On both sides of the conveyor belt 5 cutting rollers 8, 8 'are arranged, the axes of rotation D parallel to the conveyor belt 5 and to a

Feed direction V are aligned. The glass or plastic bottles 2 are placed on the conveyor belt 5 and along the feed direction V with a

Feed rate of 0.01 to 10 m / s on the cutting rollers 8, 8 'moved past; a typical cycle time for transfer lines for bottle preparation is about one second per bottle. The glass or plastic bottles 2 are guided laterally by guided as circumferential bands 6, 7 guide elements. The bands 6, 7 are aligned parallel to the conveyor belt 5 and lie on both sides of the glass or

Plastic bottles 2, so that by friction, a certain force on the glass or plastic bottles 2 is transferable. The belts 6, 7 move in the feed direction V at different speeds; By this relative speed between the bands 6, 7, the glass or plastic bottles 2 each become one

Rotational motion forced about its longitudinal axis S. As an alternative to a movement of both belts 6, 7, a belt 6, 7 can also be designed as a stationary guide plate or friction block. In this case, a relative movement between a moving belt 6, 7 and the stationary guide plate or the friction block causes the rotation of the glass or plastic bottles 2. The band 6 - or optionally the guide plate - serves as a fixed stop and is laterally, d. H. horizontally and perpendicular to the feed direction V, not movable and thus positions the glass or plastic bottles 2 to

The flat belt 7 can be laterally manually or electrically controlled adjustable or spring-mounted and provides the floating bearing in the guide. It has the task of pressing the glass or plastic bottles 2 to the comparatively higher and also flat band 6 and to produce an efficient frictional connection with a short overall length. The glass or plastic bottles 2 are so on the

Conveyor belt 5 standing firmly clamped between the two belts 6, 7 and move from the belts 6, 7 forced to rotate about its longitudinal axis S in the feed direction V. The glass or plastic bottles 2 are passed to a sensor 1 1, the bottles counts and their size and shape or geometry can recognize. Accordingly, the cutting rollers 8, 8 'are adjusted in height and lateral orientation, so that an optimal processing of the glass or

Plastic bottles 2 is guaranteed. This process is controlled and documented by an electronic control unit or by a PC. There is also the possibility that the cutting rollers 8, 8 'manually in their height and lateral Orientation transversely to the feed direction V can be adjusted. In this case, the

Sensor 1 1 is not mandatory. The cutting rollers 8, 8 'are through

Drive units 12, 12 'in rotation about their axes of rotation D, which parallel to

Feed direction V are aligned, offset. In sections A, A 'the rotating glass or plastic bottles 2 are guided past the cutting rollers 8, 8', without interrupting the rotational and longitudinal movement; d. h., the process is continuous. Alternatively, there is also the possibility that the process is carried out discontinuously. Fig. 2 shows a schematic view in the feed direction V of the device 1 according to the invention as shown in FIG. 1. The cutting rollers 8, 8 'engage in different heights on the glass or plastic bottles 2 with knives 9 to adhesive labels 3, 3' or bands to remove or at least to scratch. Since the glass or plastic bottles 2 are clamped between and guided by the belts 6, 7 and the conveyor belt 5, they are thereby supported against forces exerted by the cutting rollers 8, 8 '. By a relative movement between the two bands 6, 7, the glass or plastic bottles 2 are forced to rotate about their longitudinal axis S. Thus, the cutting rollers 8, 8 'the glass or plastic bottles 2 process fully. The knives 9 of the cutting rollers 8, 8 'are mounted on a base body 10. The cutting rollers 8, 8 'are designed so that the base body 10 does not touch the glass or plastic bottles 2. The cutting rollers 8, 8 'rotate at a speed of between 0.1 and 1000 rpm in such a way that during the passage of a glass or plastic bottle 2, at least one blade 9 touches the glass or plastic bottle 2 and adheres to a part Downward movement of the engaged knife 9 can remove. The cutting rollers 8, 8 'are constructed so that at least one blade 9 is mounted on the circumference of a cutting roller 8, 8'. As an alternative to the illustrated cutting operation, which is from top to bottom, the cutting process can also be carried out from the bottom up; For this, the cutting rollers 8, 8 'must be oriented differently and an additional support is provided from above, which engages, for example, in a bottle opening.

In Fig. 3 is a section through a cutting roller 8, 8 'is shown. On the main body 10, which has a substantially circular cross section, knives 9 are attached. A knife 9 is connected to at least one fastener 13 on Basic body 10 attached. This attachment can be flexible via a compression spring 14. The compression spring 14 is mounted between the knife 9 and a spring plate 15, wherein advantageously the fastening element 13 is guided by the spring plate 15. This ensures that the knife 9 has a defined contact pressure on the glass or plastic bottles 2 during cutting adhering parts. With such a flexible blade 9 and minor differences in shape of the individual bottles can be compensated. By the main body 10 of the cutting rollers 8, 8 ', the bottles are supported and guided and held at a minimum distance from the knife 9, so that the bottle can not tilt in the direction of the cutting roller 8, 8' and thus in a knife 9, whereby the system blocks would become. Thus, the vessels are not damaged during cutting and the device 1 is not blocked by tipping vessels. The main body 10 can be made in various materials, such as plastic, elastomer, metal or wood. The knife 9 is attached to a certain angle 16 to a tangent to allow the best possible cutting engagement angle. The main body 10 has a recess 17 in which the knife 9 is inserted and bears radially and tangentially. A cutting force can either by the positive radial and tangential recess 17 or through the

Fastener 13 are received. The main body 10 is provided with a bore 19 parallel to the axis of rotation D of the cutting rollers 8, 8 '. In this bore 19, a rod 18 is mounted, which thus runs parallel to the surface of the base body 10. The fastening element 13 is provided with a thread, which is screwed into a mating thread in the rod 18. Thus, a knife 9 with a plurality of fasteners 13 in the longitudinal direction of the rod 18 and thus attached to the main body 10. The fasteners 13 are in the

Threaded the rod 18 secured against rotation.

The device 1 is controlled in such a way that at least one knife engagement occurs during a passage of a glass or plastic bottle 2, but advantageously several. This is achieved in that the cutting roller 8, 8 'is carried out so long or so many blades 9 distributed around the circumference that at least one or more blades 9 come to each bottle during its passage through a section A, A' for engagement. Preference is given to several cutting operations per bottle, so that the most complete removal of adhering parts can be done. The glass or plastic bottles 2 pass successively through the two sections A, A ', in which they from the cutting rollers 8, 8 'are processed at different heights. The rotational movements of the cutting rollers 8, 8 'are such that a cut can be made on a bottle from top to bottom and the bottle against against the cutting rollers 8, 8' exerted cutting forces by the conveyor belt 5 and the belts 6, 7 are supported; the force support follows continuously during the rotation of the vessels and during their transport movement. The conveyor belt 5 transports the vessels in a row, which they can touch; but no cutting forces are transmitted from one vessel to another, they are taken up exclusively by the conveyor belt 5 and by the belts 6, 7. Thus, the vessels do not interfere or interfere with each other during transportation.

The cutting rollers 8, 8 'may be the same or in different embodiments. In addition to the described or illustrated embodiments, multiple cutting rollers with numerous knives 9 distributed around the circumference are also possible. In addition to knives 9 can also cutting needles, cutting tips, brushes or

Wire brushing use find. Thus, successive cutting, brushing and scratching methods can be used to remove or at least scratch the adhered parts. Partially removable parts are easier to remove from the vessels in a subsequent washing process. The fallen parts are collected with a safety gear and transported away to be recycled.

As shown in FIG. 1, after the sections A, A is another sensor 20

arranged, which detects whether all adhering parts have been removed or whether capsules etc. hang on the glass or plastic bottles 2. In the latter case, the corresponding bottle is discharged after the sensor 20 and fed to the process again.

As an alternative to a cutting roller 8, 8 'can also be used a knife bar with linear motion, which in a directed from top to bottom movement the

Knife blade to the capsule or the label 3, 3 'leads and this or this of the glass or plastic bottle 2 cuts or tears. It can also be a kinematic

Cutting movement to be performed, consisting of a combination of a

Rotary movement and a linear motion exists. Thus, a cutting movement be executed, which moves the knife blade in a certain space curve. This cutting movement in space can be optimized by a numerical control (CNC-controlled) so that this cutting movement follows the contour of the vessel and thus encapsulated special forms of vessels and bottles and / or can be cleaned from labels 3, 3 '.

It is also possible to perform with a cutting roller 8, 8 'with a small diameter, a free-form movement of the cutting roller 8 in the room, the one of

Control unit is calculated and specified. In Fig. 4, such a construction of a cutting roller 8 with a Z-shaped suspension for producing any manually or numerically controlled movement of the cutting roller 8 is shown. With this device, the cutting roller 8 can start special contours and thus process complex bottle geometries. In Fig. 5 is a schematic view in the feed direction V of a device 1 is shown, which has a Aufschraubmechanismus for unscrewing

Screw caps of screw-in containers, in particular glass or

Plastic bottles 2, has. The Aufschraubmechanismus includes a friction block 21 and a screw unit 22, which are adjustable to the screw caps or screwed cover 4. The glass or plastic bottle 2 is through

Feed devices 23, 24 on two sliding guides 25, 26 along the

Feed direction V moves; In this case, a rotation about the longitudinal axes S is possible, but not absolutely necessary for the Abschraubmechanismus. By adjusting the spring-mounted friction block 21 to the screwed cover 4, a frictional force is generated. To generate a torque opening the screw cap a corresponding counterforce is generated by the employed screw unit 22, for which purpose it is moved with a corresponding conveying speed or with a

Rotational speed rotates. For a clearer illustration of the method, FIG. 6 shows a schematic top view of the device 1 according to FIG. 5 along the section VI-VI (lower area) and FIG. 7 shows a schematic bottom view of a device 1 according to FIG. 5 along the section Vll-Vll (upper area, screw-on mechanism) shown. As an alternative to an embodiment of the screw-on mechanism according to FIGS. 5 to 7, in which the screw cap is set in rotation, wherein the vessel does not have to rotate, an embodiment is also conceivable in which the bottle is replaced by bands 6, 7 (or by a band 6 or 7 together with a friction block) set in rotation and the

Screw cap only translating, so without rotation, is performed. That is, the screw cap of a rotating bottle transported by a

Feed mechanism clamped, this feed mechanism two

Feed devices comprises, which are engageable by two sides of the screw and work on both sides at the same speed, namely the feed rate of the bottle. By the rotation of the bottle and the fixation of the screw cap relative to the bottle by the feed mechanism, the screw is now unscrewed (actually the bottle is unscrewed from the screw). By a pitch of the feed mechanism relative to the feed direction V of the transported bottle, the screw cap can be removed from the bottle and transported away via a guide plate.

In summary, both variants of the Aufschraubmechanismus are so too

characterize that the screw caps are set in rotation about the longitudinal axis S of the vessel relative to the translating and / or rotating vessels, thereby unscrewed from the vessels and then removed.
