Description

Compaction station for compaction

Bulk material in open-mouth bags and procedures

Besehreibung

The present invention relates to a compacting station with at least one compacting device for compacting bulk bags filled with bulk materials. The invention is

used in particular in connection with a device, as they have become known from WO 2016/046302 AI. In such a known device bags are filled, for example, with bulk materials such as cement, high-quality grout or other building materials. Cuboid sacks are produced with a high degree of compaction.

In the prior art are with WO 2016/046302 AI a

Apparatus and a method for filling open socks has become known, wherein in this known device the

Filling weight of a filled open bag between about 1 kg and 10 kg. With the known device

in particular bulk materials such as cement or high-quality grout or other building materials filled into open-mouth bags, which are also referred to as bags or small bags. In the known device, the bags can directly in a device upstream of the device as part of the filling process

getting produced. For this purpose, for example, a flat film is passed over a forming shoulder and the flat film is welded there to form a film tube. In the known device, the open bag to be filled is received in a receiving box and filled there. With the known device can be filling box-shaped open sacks, which are compressed during the process. At the end of the process cuboid open-mouth bags can be packed. The known device works satisfactorily.

However, when the open-sacks filled with bulk goods are picked up by many people, or when the open-sacks are pressed too hard (or fingered extensively), the sacks may soften and lose their exact parallelepiped shape.

It is therefore the object of the present invention to provide a device with which filled open sacks keep their cuboid shape even better.

This object is achieved by a compression station with the features of claim 18 and by a method with the

Characteristics of claim 15 solved. Preferred developments of the invention are subject of the dependent claims. Further advantages and features of this aspect of the invention will become apparent from the general description and the description of the

Embodiments.

A compacting station according to the invention comprises at least one compacting device for compacting bulk bags filled with bulk materials. The compression device comprises a container having a tubular inner wall and a receiving space for receiving a filled offensive bag. Furthermore, a support unit on a height-adjustable lifting device

intended. The support unit is adjustable in height, in particular by means of the height-adjustable lifting device relative to the container. The support unit is supported in a lowered position of the lifting device from below and is in a raised position to take over a filled

Offensacks suitable from an adjacent conveyor. Furthermore, a lowerable from above punch is included, which acts in a lowered position from above on the bulk material and in a raised position, allows for the transfer of a filled offsack from an adjacent conveyor.

The compacting station according to the invention has many advantages. A considerable advantage of the compression station according to the invention is that a filled open sack is compressed within a container. As a result, the opening bag is stamped on the shape of the container. For example, cuboid filled open sack can be produced with a high compression.

In particular, the support unit is supported or set down in a lowered position of the lifting device on support hooks of the container and supported by these from below. But it is also possible for other support from below.

Preferably, the container via a compression gearbox can be raised and lowered periodically by a container stroke. By periodically raising and lowering the container relative to the ram, a pounding or jarring compaction of the bulk material filled in the open sack is ensured. The container stroke is preferably less than one fifth, and more preferably less than one tenth of the length of the container. In particularly preferred embodiments, the container stroke is less than 50 mm and in particular less than 20 mm and preferably less than 10 mm. In a specific embodiment, a stroke of 6 mm is used. Depending on the container size and in particular the container height and the desired

Degree of compaction and the compaction ability of the bulk material, the hub can be selected.

Preferably, the ram is driven by a pneumatic drive. The pneumatic drive can have at least one

Include pneumatic cylinders. Preferably, the

Compression gear driven by an electric motor. The combination of one pneumatic drive and another

Example electric drive has the advantage that the Pneumatic drive can compensate for pressure surges, so a

Overload is reliably prevented.

Another significant advantage of a pneumatically operated press ram and a compactor is that the press ram is automatically tracked with increasing compression (due to the pneumatics). Even with increasing compaction, it is ensured that the acting force remains (practically) the same. Alternatively, it is also possible that the press ram stands still and the container is raised and pneumatically tracked.

In advantageous embodiments of the container is a

Dedusting appropriate. It is possible, for example, that the upper container opening at least partially by a

Dedusting opening is surrounded. For example, on one side of the container or it may be on multiple sides of the

Dusting column be provided container, which suck the upper portion of the container and thus reliably dissipate a large amount of possibly exiting dust.

In preferred embodiments, an upper portion of the container is conical or funnel-shaped or the like

designed so that an insertion of an offensive sack in the

Container is facilitated.

In advantageous embodiments of the compression device is assigned to a slide, swivel arm or the like or the compression device has a slide, with which the filled open bag side of, for example, the

Conveyor on the support unit and / or pushed back back is. In addition, an offensive bag to be compacted can be removed from the conveyor and compacted in the compression station, while the conveyor itself

continues running and, for example, a second filled open bag transported to a second compression device of the compression station. About the parallel and simultaneous compression several filled open sacks can the

Processing speed can be increased with a long residence time in the compression station.

In all embodiments, it is preferred that the slider comprises suckers to keep the top bag wall open.

Preferably, the slider comprises suckers at different heights, around the upper bag wall of different heights

Open socks each purpose to keep open.

In all embodiments, it is possible that the support unit can be raised via a short-stroke device. This will allow the support unit to transfer from the support unit to the transfer unit upon transfer of a compacted offensive bag

Conveyor is positioned slightly higher than the level of the conveyor, so that a slight removal of the already compressed offensive bag is allowed on the conveyor. Conversely, the support unit slightly below the

Height levels of the conveyor are placed when the slider is transferred to an offensive bag to be compressed from the conveyor to the support unit. For example, the short-stroke device can perform a stroke of 5 mm or 10 mm or 20 mm or an intermediate value. At a stroke of 10 mm then there is preferably in each case a height difference of about 5 mm, when the conveyor to be compressed offense bag is passed by means of the slider to the support unit and there is also a height difference of about 5 mm, if subsequently after the compression of the Open sack from the support unit to the

Conveyor to be pushed back again.

In all embodiments, it is preferred that the press ram is equipped with a suction device.

In all embodiments, it is preferred that the

Compression station comprises at least 2 compression means or 3 compression means or more compression means for the compression of bulk bags filled with open-mouth bags. In this case, the compression devices are preferably each arranged one behind the other and connected to one another via a conveyor. This makes it possible to perform a multiple compression of a filled open bag. However, it is also possible in particular to simultaneously compress a filled open sack at several compression devices, so that the processing speed increases accordingly.

The method according to the invention serves for compacting bulk material in a bag filled with bulk material. In this case, a filled open bag is placed on a support unit. The

Supporting unit with the filled open bag placed thereon is lowered into a tubular receiving space of a container so far that the product level in the tubular

Recording room of the container is located. The support unit of the

Container then stands on support hooks or is supported from below. A press stamp appears simultaneously or

preferably already from above into the open end of the

Offensacks and acts from above on the bulk material, while from below the support unit (supported by the support hooks) presses against the bottom of the bag. The lifting device moves

especially down and separates z. B. of the

Support unit when the support unit strikes the support hook.

The inventive method allows an advantageous

Compaction of bulk solids in open sacks, whereby a parallelization to increase the performance of the entire system or a higher degree of compaction of the entire system is possible for a given overall performance.

Further advantages and features of the present invention will become apparent from the embodiments, which are explained below with reference to the accompanying figures. show the figures

FIG. 1 shows the basic structure of a filling machine 1. FIG. 1 shows an overall perspective view of FIG

Filling machine 1 for filling bulk materials (and possibly fluids) into flexible and open-topped sacks 3. The sacks 3 to be processed are made of a flexible material and in particular of a plastic material. The filling machine 1 comprises a filling carousel 2, a bag source 70 and an intermediate silo 80 for intermediate buffering of the bulk material to be filled. As bag source 70 here is a film roll 71 is provided, on which a film web 72 is wound. The unwound from the film roll 71 film web 72 is a forming shoulder 73rd

fed. There, the film web 72 is made of plastic film around the shoulder and it is welded a longitudinal seam, so that a continuous film tube is formed.

At the transfer station 60, the bag bottom is made in the appropriate welds transverse to the longitudinal extent of

Tube film are introduced. The tube film held in the appropriate cross-section is conveyed further and into the

Receiving box 62 of the transfer station 60 brought. There, the open bag 3 to be filled is received in a form-fitting manner. For the supply, the tubular film is cut off suitably so that the open-top end of the open bag is produced.

It is also possible to produce the open-topped bags from an already prefabricated and, for example, extruded

Film tube or the supply of completely prefabricated flexible bags or bags from a magazine or the like.

In Figure 1, the pivot position 63 of the transfer station 60 is shown.

The device or filling machine 1 has a base frame, on which the filling carousel 2 and the other components are fastened. The part 5 of the device is fixed, while the part 6 rotates in operation. There are various treatment stations provided at the individual filling stations, wherein at a treatment station, the filling in the coarse flow and at a further treatment station 41, the filling is carried out in fine flow. At further treatment stations is a

Compaction of the filled bulk material.

The filling carousel 2 is operated clocked here. From the

Intermediate silo 80 is supplied to the required bulk material. If the compression achieved on the filling carousel 2 is not yet sufficient, a compression station 100 can be connected downstream, as shown in FIG. The

Compaction station 100 of FIG. 2 here comprises five

different compression devices 101, here

arranged one behind the other.

Each compression device 101 comprises a pressing device 123, each via a pneumatic drive 124 in the form of a respective pneumatic cylinder. By means of a lifting and lowering unit 126 is a ram 120 can be raised or lowered. In the

lowered position is then exerted on the pneumatic cylinder 124 pressure on the bulk material.

The filled open sacks 3 are conveyed via the conveyor 106, which is preferably designed as a conveyor belt. If a compression is to take place on one of the compression devices 101, the storage flap 108 is retracted or

pivoted in order to position the opening bag defined in the conveying direction and at the appropriate moment the corresponding slide 105 is activated. Thus, an offensive bag 3 to be compacted is withdrawn from that of the conveying device 106 and introduced into a container 110. Dust removal lines 130 are provided to remove dust during compression. With the

Lifting device 102 may not be visible in Figure 2

Support unit 231 are adjusted in height.

Figure 3 shows a schematic cross section through the

Compaction station according to Figure 2. At the top is the

Pressing device 123 with the pneumatic cylinder 124 recognizable, at the bottom of a linkage and then the so

coupled punch 120 connects. The real one

Pressing surface of the ram 120 can with a

Extraction 125 be equipped to an effective

To cause venting. By the suction device 125 air can be effectively sucked out of the bulk material. The slider 105 is here in the position above the container 110, which has reached the slider after an openable bag to be compressed 3 has been transferred from the conveyor 106 to a support unit 131. The open bag 3 is shown here by dashed lines, as well as a in the open bag

immersed ram 120, which is shown in dashed lines in the lowered position 121. In the raised position 104, the open sack 3 rests on the support unit 231, which is detachably coupled to the layer composite 203 via magnets 232.

When the lifting device 102 is in the lowered position 103, the support unit 231 rests on hooks 116 at the lower end of the container 110. As a result, the support unit 231 is decoupled from the lifting device 102, since forces in

vertical direction from above to the bulk material or the Offensack directly via the hook 116 and the container 110 are derived. The magnetic connection between the support unit 231 and the layer composite 203 prevents tilting of the support unit 231 in the tubular inner wall 111 during lowering. In order to ensure a good adhesion of the magnets at any time, it is possible to individual fluid outlet openings z. B. to leave at an oblique angle in the upper cover plate or end plate to clean them from it depositing particles.

The layer composite may consist of individual (and prior to assembly or production) separate plates, which form a one-piece or multi-part plate composite. It is possible and preferred, however, that at least a part of the layer composite or the entire layer composite is formed in one piece as a whole and z. B. is produced in an additive manufacturing process and / or as SD printing. Then, the entire layer composite can be manufactured in one manufacturing step. It can

Guide channels or fluid passages z. B. be made by omitting material.

The container 110 has a tubular receiving space with a tubular inner wall 111. The cross section is here

rectangular, so that cuboid open sacks arise. The upper portion 115 of the container 110 is slightly conical in order to facilitate insertion of an offensive bag to be compressed.

FIG. 4 shows a part of the compression device 101

shown in perspective. At the upper end of the container 110 is inside the layer composite 203 with the magnets 232nd

recognizable on the not shown here in the operation

Support unit 231 rests. On the support unit 231 or a slide plate (not shown) arranged thereon, a bag to be compacted is turned off. Subsequently, the bag to be compacted together with the support unit 231

lowered, so that the compression device of the raised position 104 shown in Figure 4 in the in Figure 5

shown lowered position 103 is transferred.

At the lower end of the bottom open container 110 is the

Support unit 231 recognizable, which now on the hook 116 of the

Container 110 rests. This will decouple the

Lifting device 102 caused by the support unit 231. A

Height adjustment of the lifting unit 102 via the

Linear guide 233, which includes a motor.

The recognizable in Figure 4 motor 235 is used to drive the

Verdichtungsgetriebes 113, with a periodic

Stamping movement of the entire container 110 takes place.

In order to obtain a decoupling of the lifting movement of the container 110 from the dedusting 130, the dedusting 130 is decoupled from the container 110. This can be done, for example

take place that the dedusting 130 is received in a slot 131 on the container 110, so that a sufficient

Vertical offset is possible. The slot is sealed by a rubber flap.

The motor 234 recognizable in FIGS. 4 and 5 serves to drive the conveyor belt 106. FIG. 6 shows a part of the compression station 100 or the cleaning device 200 with which an effective cleaning of the inner wall 111 of the container 110 can take place even when a compressed offensive bag 3 is removed from a container 110. For this purpose, the cleaning device 202 is used with the layer composite 203.

The layer composite 203 comprises a plurality of layers 204 to 208, the structure and function of which will be explained below with reference to FIGS. 7 and 8. FIG. 7 shows a plan view of the fluid-conducting layer, in particular in the form of a fluid control plate 205, while FIG. 8 shows a schematic exploded view of the layer composite or plate composite 203.

The cleaning device 200 can be raised and lowered via the lifting device 102. The laminate 203 includes as the bottom plate here designed as a bottom layer or bottom plate end plate 204. On the bottom plate 204 is the

Fluid supply 212 connected via a fluid supply port 213. About centering pins 229 and / or screws is the

Layer composite 203 in total in the assembled state

held together.

On one or more of the plates or layers 204-208 brushes may optionally be attached or formed, which the

Support cleaning of the inner wall.

Above the bottom plate 204 is the fluid guide plate 205, on which a plurality of fluid outlet openings 210, 211 are formed distributed over the circumference.

The fluid outlet openings 210, 211 form the ends of the

Conduction channels 215, 216, each extending from a radially inner portion 219 to the outer side 220 and the outer edge on the peripheral surface 217. Here are the guide channels 215, 216 as recesses or passage opening in the Fluid guide plate 205 is formed. The respective guide channels 215, 216 are separated by material webs 222 from each other. Here, in principle, all the guide channels 215, 216 are substantially star-shaped, so that distributed over the entire circumference fluid outlet openings given here in particular as

Blow holes for blowing air serve as a cleaning medium. Here is located in the Fluidleitplatte 205 a central

Through opening 225, which has no direct connection to the guide channels of Fluidleitplatte 205.

Above the fluid guide plate 205, a spacer plate 206 is used, which has a distribution trough 223 (distribution space), which is designed here as a passage opening in the spacer plate 26. Via the distribution trough 223, the fluid to be distributed (in this case air) is distributed to all guide channels 215, 216, so that air is blown outward through all the guide channels 215, 216 via the air supply through the central fluid supply opening 213. About the cross-sectional area of the individual guide channels, the

Intensity of the blown air can be adjusted.

It is possible that separate feedthroughs 226 are formed, through which a supply of further components can be realized. For example, vacuum can be conducted through the feedthrough feedthrough 226. Or compressed air is being carried out. It is also possible that electricity or

Sensor signals are performed by the feedthrough 226.

Above the spacer plate 206 is still a cover plate 207 is provided, to which finally the end plate 208 connects.

If appropriate, the cleaning device 200 can also only be a plate composite or layer composite of, for example, three

Include plates or layers, wherein the middle layer or plate then z. B. is designed as Fluidleitplatte. In all cases, it is possible that the guide channels are formed in the Fluidleitplatte as through holes. It is possible Also, that the guide channels are milled, for example, in the surface of Fluidleitplatte.

In the top plate 208 additional functions can be integrated. Thus, for example, a magnet 232 (or more) may be provided there or further actuators may be attached, such. B. a Kurzhubeinrichtung 140, by means of

Supply bushings 226 is controlled.

A cleaning device 200 can also be used in a corresponding manner for cleaning the receiving boxes 30 or 62 of the filling machine 1. Thus, automatic cleaning of the receiving boxes 30 and / or 62 can take place after each change of bag.

With the compression station, the compression of the filled into an open bag bulk material can be significantly increased. It is possible to provide a compression station in which a plurality of compression devices are arranged one behind the other, so that a parallel operation and a parallel compression of a plurality of filled open sacks is possible. It can via a slide or the like to

compressed offensive bag are pushed by a conveyor such as a flat belt conveyor to the compacting device. The actual compression takes place in the container with the tubular inner wall, wherein from above a ram is lowered and immersed in the open-top bag, while the bottom of the open bag is supported by a support unit on hooks of the container. At the same time, the

Tank environment are sucked through a dedusting.

During pressing with the ram, the container can perform a periodic raising and lowering movement, the

Compaction process significantly supported. At the same time, air can be sucked out by the press punch. This can be the

Contact surface of the press ram, for example by a

Wire mesh or wire mesh are formed through which can be sucked. If dust should escape during the compression process, the inner wall of the container 100 can be cleaned of adhering bulk material particles via the integrated cleaning device. For this purpose, the layer composite 203 of the cleaning device 202, wherein on the peripheral surface 217 of the plate assembly 203, a plurality of fluid outlet openings 210, 211 is formed, through which a fluid flow can be directed to the inner wall of the container.

The control of the airways can be done in a simple manner by a corresponding design of Fluidleitplatte, wherein the intensity by a cross-sectional adaptation or the number of outlet openings 210, 211 per circumferential length

can be adjusted accordingly. The orientation of the

Air outlet 210, 211 defines the direction of flow of the fluid and thus the direction of the fluid flow 209.

If, for example, above the plate assembly 203 further devices are provided, which are also to be controlled, a supply feedthrough 226 may be formed on the layer composite, for example a

Compressed air or vacuum connection or a compressed air or

To allow vacuum transmission.

Since the outer dimensions of the panel composite are regularly adapted to the inner dimensions of the container 110, a simple media exchange or data exchange can be realized by a supply bushing 226.

The construction of the compression station 100 and the structure of the

Cleaning device 200 is each easy and inexpensive to implement.

FIG. 9 shows a detail of a lifting device 102, wherein a short-stroke device 140, which can adjust the plate 208 by +/- 5 mm in height, is mounted on the layer composite 203. As a result, the support unit 231 is adjusted accordingly. The Kurzhubeinrichtung 140 could also be integrated into the linear guide 233.

The layer composite 203 here comprises the layers 204, 205 and 207. The layers 204 and 207 between them
