BALING PRESS FOR STRAW-LIKE OR FIBRE-LIKE MATERIALS

The invention relates to a baling press for straw or fibre like materials according to the preamble of claim 1.

In order to minimise the energy consumption for heating and cooling as well as to reduce the noise, buildings today are extensively insulated. The so-called passive houses, which no longer need the classic building heating due to their elaborate external insulation, are especially economical. Materials such as foamed plastics (expanded or extruded polystyrene) as well as mineral fibres (glass or mineral wool) are often used for the insulation.

These insulating materials however have a few disadvantages. They are easily flammable to an extent and practically cannot be extinguished once they are ignited. However, what is true for all the insulating materials mentioned is that their disposal is expensive in case the building is being demolished. Other serious disadvantages of these materials include the high primary energy requirement during their manufacturing, their low moisture tolerance, mostly low permeability as well as their lack of reusability or recyclability. Furthermore, some of the conventional insulating materials contain hazardous additives (flame retardants and the likes), or release respirable fine dust particles.

Renewable and recyclable insulating materials such as wood fibres, flax, hemp and sheep's wool are thus being used more and more frequently. These natural materials are biodegradable and do not put strain on the environment. Of late, straw bales are also being used for insulation of buildings. In fact, load bearing walls of a building can be completely built from straw bales. The major advantages of the use of straw are its the ample regional availability, its positive CO2 balance, the absence of any additives in it as well as its extraordinary structural biological properties. Thanks to the existing technical constructionrelated approvals (including European technical approvals), there are no obstacles in the use of straw as construction and insulating material even legally. Till now, straw bales were available for use as insulation material only in the conventional sizes (standard sizes of baling presses of various agricultural machinery manufacturers). However of late, straw is first pressed into big bales on the field and then subjected to stationary further pressing as part of a second work step.

For this, the big bales are transported to the stationary facility and disintegrated, i.e. loosened, and the straw is then once again pressed into bales of the required (small) size. The bales in their current size must then be transported to their place of use.

Another problem of known straw bales, which arises during this process of re-formation, is the absence of different sizes. This leads to limited insulation thickness options, in turn resulting in lack of acceptance by the processors (wood workers, carpenters, manufacturers of prefabricated houses). Even bales must be frequently expensively cut since only few dimensions are available.

The objective of the invention is to create a baling press for straw-like or fibre-like materials that can be transported from one place of use to another very easily. Another objective here is to design the baling press such that it can be used to manufacture various bale sizes.

According to the invention, these objectives are achieved by means of a baling press for straw-like or fibre-like materials with the characteristics from claim 1. By providing a base frame on which components of the baling press are mounted such that they are movable and/or swivellable between a transport position and a working position, wherein the outer dimensions of the baling press with all the components in their respective working position are more than the dimensions of the base frame and the outer dimensions of the baling press with all the components in their respective transport position are less than the dimensions of the base frame, it is possible to transport the baling press very easily without requiring a crane or any other heavy equipment for loading and unloading .

The base frame can be designed as a swap body or a gliding roller structure. It can however also be permanently installed on a truck or a trailer. A swap body usually means an exchangeable load carrier that can be separated from the carrier vehicle, similar to an ISO container. Swap bodies are connected to the carrier vehicles intended for transport using so-called twist locks. The basic lock size of a swap body corresponds to that of a 20-feet ISO container such that a usual container transporter can be used for the transport of the swap body. A swap body can be equipped with a container, but can also have a structural frame for a tarpaulin covering.

A gliding roller structure is usually transported with a vehicle having a hook lift. In addition to the hook lift, the vehicle is also equipped with cylindrical glide rollers, using which the structure is moved when unloading and loading with the help of the hook lift. During transport, the gliding roller structure is locked on to the carrier vehicle using bolts.

When fixing the base frame on to a trailer or a truck, it must be noted that the relevant carrier vehicle cannot be used for any other purpose during the production of bales. This however economises the components that serve in the loading and unloading of the structure.

The baling press, according to this invention, has been conceived for the production of straw bales. However, it goes without saying that it can also be used to press other straw-like or fibre-like materials into bales.

In case of a mobile baling press, a major part of the costs for transporting the straw is dispensed with, in comparison with a stationary structure.

Further details and advantages of the invention have been specified in the dependent claims.

In order to be able to load or unload the mobile baling press on to or from a truck or a trailer without the use of an additional crane, braces are installed on the base frame, which can be moved between the transport and working positions and whose height can be adjusted. In particular, these braces are hydraulically moved. It is especially advantageous to equip each of the braces with a control unit so that the settings can be directly configured on the brace itself and the brace can be adjusted according to the relevant floor condition.

In the transport position, the baling press can be sealed using a cover and four side walls. However, opening such a closed container at the place of use of the baling press would be a time-consuming process. It is therefore especially advantageous to install a structural frame that allows all the necessary movements of the components. The base frame can then be sealed using tarpaulin covers.

It should be possible to operate the mobile baling press anywhere. It should also be usable in places where external energy cannot be supplied. Therefore, a combustion motor, in particular a vegetable oil motor, is provided on the base frame.

A generator that can be operated using combustion motors is provided to ensure current supply for operating the components even in the field.

Insulating materials must have reproducible insulation values. In order to be able to ensure this, only a small quantity of foreign materials and contamination can be tolerated. If straw is pressed into big bales on the field at the time of grain harvesting, certain amount of dirt in the straw is unavoidable. It is therefore advantageous to have a dust extraction system with a filter, which can be moved between its transport and working positions. This ensures effective cleaning, and the dust extraction system can still be brought to such a position at the time of transport where it cannot perform its task, but can be well-integrated into the place available on the swap body. The dust extraction system is mechanically moved to both its possible positions using hydraulic cylinders.

In a cleaning unit, the material to be pressed is usually loosened such that the contaminations and foreign materials can be extracted downwards. In order to be able to carry out such a cleaning process and to be able to make space available for it on the base frame, a cleaning unit is provided, which can be swivelled between its transport and working positions using two jibs, and in particular can be swivelled manually.

Particularly advantageously, the cleaning unit in its working position approximately corresponds to the dust extraction system in its transport position. In this way, it facilitates the connection between the cleaning unit and the dust extraction unit, which is necessary when both the components are in their working positions.

The equipment for feeding the straw-like or fibre-like materials can be designed as simple transport equipment that feeds the mobile baling press with loose material. However, advantageously, it is designed as equipment for disintegrating big bales so that big bales that have already been pressed can be disintegrated and pressed in a new size. In its transport position, the equipment is fixed upright on the base frame so that it can still be positioned within the scope of the base frame. However in its working position, this equipment must be in an angled position so that the big bales that are placed on it are securely retained. The equipment for disintegrating the big bales can therefore be swivelled between its transport and working positions using levers of different lengths. In this way, the equipment can be slightly raised and set on its lower end at the same time. Advantageously, this movement is carried out mechanically with the help of hydraulic cylinders. It must be emphasised that the equipment for disintegrating big bales can naturally also be used for feeding loose material into the press module.

At the time of their output, it must be possible to stack the pressed bales. It is thus advantageous to have equipment for depositing the pressed bales, which can be swivelled between its transport and working positions, where in the working position, a foot can be extendable downwards and a deposit table can be adjusted in height. This makes it possible to place equipment that is very flat in its transport position under the output opening of the press module. In the working position, the deposit table can be lowered slowly so that the pressed bales can be stacked in several layers on a pallet placed on the deposit table. This lowering can be carried out automatically if the deposit table is equipped with a weighing device. The weighing device is necessary for checking and documenting the bale thickness at the same time. This deposit equipment is also preferably hydraulically operated. In order to be able to pack a completely loaded pallet on the deposit table in a foil, the deposit table has, particularly advantageously, an electrically operated rotary plate.

It should be possible to produce bales in different sizes using the baling press. This can, for example, be done by dividing the floor of the press channel into multiple individual components as per their length, wherein these components are individually adjustable in height. If the side walls of the press channel are also adjustable, a wide range of bale sizes are possible, depending on the number of individual components of the floor. The switching can be done in a few steps or mechanically.

However in order to be able to use an existing press module, the invention specifies the use of elements installable in the press channel, which change the crosssection of the press channel. A reconstruction of the entire press module can thus be avoided and expenses can be limited.

In both the abovementioned variants, the cross-section of the press channel is changed. However since the press ram must practically entirely cover the cross-section of the press channel, advantageously different press rams are installable, whose size is adapted to the changeable crosssections of the press channel.

Further details and advantages of the invention will become apparent from the description of an exemplary embodiment, which is explained in detail with reference to the drawing.

Further details and advantages of the invention have been provided in the description of a design example that will be explained in detail with the help of the drawing.

In the	drawing description, it is assumed that the mobile
baling	press, according to the invention, is used for the

production of straw bales. It must however be explicitly highlighted that the equipment can be used not only for processing straw, but also for all other straw-like or fibre-like materials such as hemp, flax, bulrush, jute,

grass,	wood and cellulose fibres, as well as for recycled
fibres,	synthetic fibres and the likes.
Fig. 1	shows a swap body with the mobile baling press 1

installed on it, as it would be mounted on a truck. The

entire

baling press is covered with cover 4. Cover 4 can

naturally be divided into several individual parts for ease of handling. Two of the braces 5 can be seen in folded and retracted state at the lower front edge under the cover 4. The baling press 1 is in the transport position and the swap body serving as base frame 2 (see fig. 2) can be carried by any appropriately equipped truck.

Fig. 2 shows the same mobile baling press with unfolded and extended braces 5. Similarly, cover 4 has been removed such that structural frame 3 is now visible. Structural frame 3 is designed such that all movable or swivellable components of the baling press 1 can be moved to their working or transport positions without parts of structural frame 3 coming in the way. Since braces 5 are already fulfilling their function, swap body 2 with the baling press 1 mounted on it can manage in the shown position even without a truck .

In Fig. 2, all the movable or swivellable components of the baling press 1 are in their transport position. The actual press module 13 is permanently installed on the base frame 2. The same is applicable for the combustion motor 21 that is visible only in outlines here. Both the components have considerable weight and can be moved or swivelled between the transport and working positions only with great difficulty

The press module 13 has press drive 14 and belt pulley 15. The press drive 14 is connected to a gearbox, which executes all the movements necessary for the pressing process, via a V-belt and another belt pulley that is not visible here.

A cover 22 is provided over th ecombustion motor 21 and protects it from environmental factors even when the tarpaulin cover 4 has been taken off. Another cover can also be provided on the side, but it would have to be folded up in the working position to ensure good ventilation .

In Fig. 3, the movable or swivellable components are already in their working positions.

The following explanations about the shown components are with reference to both the figures.

At the big bale feeding device 6, the scraper floor in the transport position is aligned at approximately right angle to the base frame 2 and the big bale support 7 is also folded up. In this position, the big bale feeding device 6 takes up very little space on base frame 2. In the working position, the feed roll 8 is also visible.

The extraction and filter unit 10 is installed on a mobile frame 11. The extraction and filter unit 10 is moved using a hydraulic cylinder that is not visible here. In its transport position, the extraction and filter unit 10 occupies the place that is intended for cleaning unit 12 in the working position.

In its transport position, the cleaning unit 12 is parallel to press module 13 above the fuel tank that is not visible here. While swivelling to the working position, the cleaning unit is rotated by an angle of 90° and its outlet is brought to the inlet of press module 13. The swivel mechanism is further explained in detail below in the description of Fig. 6.

In the transport position, the deposit module 16 is positioned under the bale output of press module 13. It is hydraulically swivelled outwards over an axle by an angle of 90°. Foot 20 is then lowered till it reaches the floor. The deposit table 17 with the rotary plate 18 can then be adjusted in height using the scissor-like frame 19. The height adjustment is hydraulic, during which the rotary plate 18 is rotated using an electric drive.

Fig. 4 shows the big bale feeding device 6 in the transport position (Fig. 4a) and in a transition phase (Fig. 4b) to the working position. At the upper and lower ends, the chain drive for the scraper floor 9 that is not visible here (see Fig. 3) can be covertly seen. In the transport position, the scraper floor 9 is parallel to the feed receiving device 23 that consists of profiled pipes and whose lower end is installed upright on base frame 2.

The big bale feeding device 6 is connected to the feed receiving device 23 using two swivelling levers 24. Since the lower lever is longer than the upper lever, the big bale feeding device 6 reaches the angle shown in Fig. 4B upon swivelling. The hydraulic drive for swivelling is not visible in this illustration.

In order to bring also the big bale support 7 to the working position, the hydraulic cylinder 25 must be operated. This then leads to the working position shown in Fig. 3, where the feed roll 8 is also freely accessible.

Fig. 5 shows the actual press module 13 with two conversion kits 28-30 and 31-34 to change the bale size. The press module 13 is operated via the press drive 14, which transmits its power via the belt pulley 15 and a V-belt to the press ram inside the press module 13 in a manner that has not been shown here in detail. From this drive train, the driving force for the hydraulic pump 26 is reduced via belt pulley 27 and another V-belt.

The first conversion kit 28-30 is intended for a bale size with a cross section of 800x375 mm, which only differs in height from the original bale size with a cross section of 800x500 mm. It is therefore sufficient to just raise the floor of the press channel using an overlay. Since the prepress channel leads to the floor of the actual press channel and this outlet must be kept free, the floor elevation is divided into a press channel insert 29 before the outlet of the pre-press channel and a press channel insert 30 after the outlet of the pre-press channel. This first conversion kit contains yet another interchange press ram 28 that is adjusted to the reduced height of the press channel.

The second conversion kit 31-34 should produce bales with a cross-section of 400x375 mm, which differs from the original bale size due to a reduced height as well as a reduced width. The complete press channel insert 33 can therefore be one-piece. It has an opening in the floor into which the pre-press channel leads. In order to adapt even the pre-press channel to the reduced width of the actual press channel, lateral inserts 34 are provided for the prepress channel.

Furthermore, yet another interchange press ram 31 is included in the second conversion kit, which is also reduced in width and height and thus adapted to the changed cross-section of converted press channel. Since the piston rods intended for the original press ram do not fit the reduced width of the second interchange press ram 31, the second conversion kit includes a correspondingly adapted piston rod 32, whose one end is adapted to the rod holder of the press module and the other end to the narrow second interchange press ram 31.

As per the same scheme, further combinations of bale heights and widths can be achieved using other conversion kits. However, using another press module (e.g. with cutting equipment and/or projection shredder, with wire connection or with foil bag packaging) can provide further options of use.

The operating principle of the swivel mechanism of the cleaning unit 12 is schematically represented in Fig. 6. The cleaning unit 12 is specified here using only a dashed line in order to provide a view of the swivel mechanism.

The cleaning unit 12 rests on two swivel cantilevers 35 and 36 that are rotatably connected to the base frame 2 at one end. The other end of swivel cantilever 35 is rotatably connected to the floor of the cleaning unit 12. The other end of the swivel cantilever 36 too is rotatably connected to the floor of the cleaning unit 12, but close to one of the narrow sides.

In the transport position, the cleaning unit 12 is approximately parallel to the press module 13 (see Fig. 6a) . The control cabinet - not visible here - is located under the cleaning unit 12. If the cleaning unit 12 is now swivelled over both the swivel cantilevers 35 and 36 to its working position (see Fig. 6b), then it goes into a position in which the inlet for the material to be pressed is below the output of the big bale feeding device 6, that is not shown here, and its outlet is opposite to the inlet into the press module 13. The swivelling can be carried out manually or using hydraulic cylinders.

Fig. 7 schematically shows the electrical wiring diagram of the mobile baling press. The central power supply unit 39 is connected to a connection 40 for external three-phase alternating current, a generator 41 operated by the combustion motor 21 and a rechargeable battery 42. The central power supply unit 39 has equipment for discharge of alternating current with 230 V and for conversion of alternating current into 12 V direct current. In this way, the mobile baling press 1 can be operated either via the combustion motor 21 or via the connection 40 for external three-phase alternating current. The rechargeable battery is made of two truck batteries of 12 V each as a composite connected in series. Alternating current with 230 V, threephase alternating current with 400 V as well as direct current with 24 V can then be provided via the central power supply unit 39.

Alternating current of 230 V is provided via the line 43. Using this line, voltage is supplied to compressor 37 for the generation of compressed air, to rotary plate 18 of the deposit table 17 with the weighing device and the hydraulic unit for the component positioning.

The three-phase alternating current is present at line 44. This supplies the press drive 14 as the largest consumer, the extraction and filter unit 10, the cleaning unit 12, the scraper floor 9 and the feed roll 8.

The line 45 supplied with 24 V direct current supplies the hydraulic unit for the braces 5. It is thus possible to position the braces even before an external voltage supply unit is installed or the combustion motor 21 is put into operation. The same applies when dismantling the mobile baling press 1 if all the components are already in the transport position and an external power supply unit has already been disconnected. As soon as a truck is driven under the swap body, the braces 5 can be retracted and folded in with the help of the 24 V direct current connection. The connection between the central power supply unit 39 and the battery composite 41 can be used to charge the batteries, and voltage can be obtained for the braces 5.

Fig. 8 shows the operation panel for the central control unit 46. This panel is basically divided in two halves, where one half is assigned to the transport on the truck and the other half to the production. Each half has different switch positions 47 for the main switch 48. The switch position 0 for an emergency stop of the unit is at the centre between both the halves and completely switches off the power.

The function of the unit has been explained in detail below. The mobile baling press 1 can be transported to the place of use very easily on a truck. During this phase, the main switch 48 of the central control unit is in the switch position Transport. In this switch position, all electrical loads are disconnected from the central power supply unit. The mobile baling press looks like the picture shown in Fig. 1.

As soon as the place of use is reached, the main switch 48 is brought to the switch position Align braces. The hydraulic unit for the operation of the braces 5 is now connected to the batteries via the central power supply unit and supplied with

V direct current. Since a separate control unit is mounted on each of the braces 5, each of the braces can be individually folded out, extended and accurately adjusted in height as per the desired position of the baling press 1 and the ground condition.

The end position of the braces should be adjusted such that the mobile baling press 1 is easily lifted from the truck .

In this position, the truck can be driven out from under the swap body 2. The cover 4 is then removed and the mobile baling press 1 looks like the picture shown in Fig. 2.

In order to be able to switch the components from the transport position to the working position, an alternating current with 230 V is now needed. For this, the connection 40 must either be connected to an external network for three-phase alternating current or the combustion motor 21 should be started in order to be able to generate power using the connected generator 41.

The main switch 48 of the central control unit 46 is then brought in the switch position Position components. In this switch position, the hydraulic unit 38 is supplied with an alternating current of 230 V via the central power supply unit 39 for the component positioning.

In the first step, the big bale feeding device 6 is brought to its working position. The entire module - as shown in Fig. 4 - is hydraulically activated for this. The big bale support 7 is then hydraulically opened.

In the next step, the extraction and filter unit 10 must be moved to its working position. The hydraulic cylinders are actuated for this which move the extraction and filter unit 10 on the mobile frame 11 from the area over the swap body in an area near the swap body. The area where the extraction and filter unit 10 was in its transport position is thus completely free and can be used for other purposes.

The cleaning unit 12 that is arranged in its transport position near the press module 13 is turned into the gap that has been formed due to the extraction and filter unit 10 being pulled out. The swivel mechanism can be seen in Fig. 6. While swivelling, the extraction opening of the cleaning unit 12 is brought in alignment with the suction opening of the extraction and filter unit 10. In the working position, the feed opening of the cleaning unit 12 is in a position in which the upper edge of the big bale feeding device 6 is located over it. The output opening of

the cleaning unit 12 aligns	with	the	input	opening	of the
press	module 13.
Now,	the deposit module 16	under	the	press	module	13 must
still	be swung out and the	foot 20 must be	lowered	till it

stands on the floor. The rotary plate 18 is now under the output opening of the press module 13.

If the combustion motor 21 is protected by side plates during transport, they must also be removed or folded up in order to not hinder the cooling of the combustion motor 21. The mobile baling press for the standard size (here, for a bale cross-section of 800x500 mm) is then ready for use.

The main switch 48 of the central control unit 46 can now be turned further to the switch position Production. In this position, only the compressor 37, the rotary plate 18 of the deposit table 17, the press drive 14, the exhaust and filter unit 10, the cleaning unit 12 and the feed roll 8 as well as the scraper floor 9 of the big bale feeding device 6 are supplied with the respective voltages via the central power supply unit 39. Furthermore, another charging unit is provided with 230 V alternating current for charging the rechargeable batteries.

It must be assumed in the following sections that, big bales - round or square - should be disintegrated and pressed into bales with a cross-section of 800x500 mm for use as wall blocks for buildings with timber frame construction or even for weight-bearing construction. For these bale sizes, the production with the mobile baling press 1 can start in the position described in the last paragraph.

For this, a big bale is placed on the big bale support 7 and pressed against the scraper floor 9 with the help of hydraulic cylinders, using which the angle between big bale support 7 and the scraper floor 9 can be changed. This angle becomes smaller and smaller as the size of the straw bales reduces.

The straw from the bales is disintegrated using straw claws that are mounted on the transverse bars of the scraper floor 9 moving upwards. The feed roll 8 moving in the other direction can be adjusted in height so that a constant flow of straw conveyed upwards by the scraper floor 9 can be set above the feed roll 8. Naturally, loose straw can also be fed into the mobile baling press 1 using the big bale feed unit 6.

The straw released from the big bales is delivered to the cleaning unit 12 at the upper edge of the scraper floor 9. The basic principle of this cleaning is well known and thus does not need to be described here in detail. The straw is roughly combed during the cleaning process so that impurities can be separated and removed from below. The dust arising in this process is sucked by the extraction and filter unit 10 and filtered out.

The cleaned straw is now transferred to the pre-press channel of the press module 13. Since the basic equipment of the press module 13 for bales with a cross-section of 800x500 mm is not a new development, the functionality should only be roughly described here. In the design

example shown here, the Quadrant 1150 RC	the press type from	module of Claas was	a baling used.	press	of
The	straw in the	pre-press	channel	is	pushed	in	the

direction of the press channel using a fork-like rake. Since the inlet into the press channel is blocked by the press ram, the straw is pre-compressed due to the movement of the rake. As soon as the press ram is withdrawn, the pre-compressed straw is pushed into the press channel due to further movements of the rake.

The straw bales are a result of the pressure of the press ram that pushes the straw against the pressure that is built up due to a narrowing press channel in the direction of the output. The narrowing of the press channel can be adjusted; it is brought about by threaded rods, hydraulic or pneumatic cylinders and mostly balanced out using spiral springs. After reaching the pre-set bale length, a cord is tied with the help of yarn needles and weavers. The finished straw bales are pushed further up to the output.

Ideally, a standard pallet is placed on the rotary plate 18 of the deposit table 17. The first straw bales that leave the press channel are moved to the right place by a worker on the pallet till the lowest layer is filled. When the first layer is completed, the deposit table 17 is lowered by a bale height using the scissor-like frame 19 so that the surface of the first layer is now under the bale output. The lowering can be done automatically using a weighing unit or manually by the worker.

Wrapping using a stretch foil can be done either after every bale layer or when the pallet is filled. A dispenser, not seen here, is provided for this, which can be adjusted in height. The free end of the foil is sealed on to the pallet or the straw bales. The pallet is then rotated by the rotary plate 18 and the dispenser is slowly moved up at the same time. When the pallet is completely wrapped, it can, for instance, be removed from the rotary plate 18 with a lift truck and replaced by an empty pallet. The rotary plate 18 is then brought back to its original height using the scissor-like frame 19.

If the straw bales are to be created in another size, the press module 13 must be converted. Depending on the desired bale size, the conversion kit 28-30 or the conversion kit 31-34 can be used for this. As already mentioned above, other conversion kits can also be be used for other bale sizes .

If the mobile baling press 1 needs to be moved to another location of use, the variable components must once again be brought from their working position to their transport position. The sequence for this is the reverse of the one used for setting up.

After a thorough cleaning, the main switch 48 of the central control unit is brought to the switch position Position components. In a first step, the deposit table 17 of the deposit module 18 is now lowered using the scissor-like frame 19. All the components from the deposit table 17, rotary plate 18, scissor-like frame 19 and foot 20 are then raised and swivelled under the bale output of the press module 13.

In the next step, the cleaning unit 12 is again switched to its transport position, parallel adjacent to the press module 13. The extraction and filter unit 10 on the mobile frame 11 can now be retracted into the formed gap. In the last step, the big bale support 7 is also folded in and the entire big bale feeding device 6 is brought back to a vertical position. The mobile baling press 1 can then either be disconnected from the external power network or the combustion motor 21 can be switched off.

As soon as the cover 4 is placed, the baling press 1 is ready for transport. A truck with equipment to carry a swap body is now steered under the base frame. When it is in the right position, the main switch 48 is brought to the switch position Align braces. The frame 2 can now be lowered by lowering the braces 5 till it rests on the truck and can then be fastened. The braces 5 can then be fully retracted and folded.

As soon as the main switch 48 is brought to the switch position Transport, the transport to the next place of use can start.
