Description

[Detailed description of the invention] Textile industry reel or reel resemblance Methods and devices for transporting cargo The present invention provides a method and apparatus for transporting cargo from a receiving location to a storage location and a vehicle. Regarding the acceptance and storage of cargo by

Transport vehicles are permanently linked to a central master computer that monitors all vehicles in operation. Control methods for transporting cargo are well known. At this time, the vehicle is unable to accomplish its mission. and is highly supported by equipment around the transport zone.

For example, in the textile industry, a wide variety of processing machines depend on the quality of each machine. Reels or reel-like goods that must be classified as such and supplied to reprocessing stations. A thing exists. This is especially true for ring spinning, open end spinning, single strand spinning, and This is an example of a winding machine and a thread winding machine. manufactured by these machines The cargo is fed to reprocessing machines such as thread winding machines and packaging machines, or relayed. It is sent to a warehouse and removed from there. Therefore, the Federal Republic of Germany patent application publication tube 3 From the specification of No. 332899, a method and device for orderly feeding out a zigzag bobbin are publicly known. It is knowledge. The zigzag bobbins produced in the zigzag bobbin manufacturing unit are They are placed in a buffer magazine and collected in a zigzag bobbin manufacturing unit and automatically sequentially. is delivered to the circulation conveyor. The circulation conveyor has hooks fixed at regular intervals. It is made of chains. The chain runs through a drive device, which allows the chain to is made to exercise. A predetermined carrying hook is recognized using a sensor and its The next transport hook is counted from among the hooks. Therefore, the reel suspended from the transport hook Continuous counting is performed. A controllable automatic reel handing device handles the traverse bob to be transported. Fit the bottle into the empty hook on the circulating conveyor.

A programmable data processing device memorizes the hook number and allows the hook to be removed. As soon as the location is reached, the bobbin is removed from the hook.

The disadvantage of this method is that the reel is hooked at each installation and removal position. An operating device shall be provided for engaging the hook or removing it again from the hook. There is no such thing. On the one hand, this increases costs and also requires a very large number of operating devices. This is because it requires a stand and a hook.

On the other hand, the flexibility of this type of system makes it possible to is impaired due to the inability to branch. Other circulation conveyor length is chain is limited by the maximum length of the chain or the maximum conveying capacity of the chain drive.

Further, from German Patent Application No. 3824874, for transporting reels Overhead conveyors are known. Reel coming from reel machine Frames are fed to the next processing point before being received by an overhead conveyor vehicle be done. The special feature of this method is that the reel frames are arranged back and forth in the transport direction, and The rod axis must be vertical. This gives the vehicle a passive trap that reacts exclusively to back pressure. It is possible to use a capture element. In terms of their type and mode of function, entrainers are Contrasted with Kasaplanker holder. The reel is adapted to the placement of the entrainer in the vehicle. The vehicle is then provided for reception at precisely defined intervals and the holding device is lowered. the holding device is lowered to a certain height, and then the reel is connected to the holding device. and moved to the upper position. At the transfer point the reel is lowered again and this If a reaction force is generated, the cage will be dislodged from the spool.

The disadvantage of this method is that receiving is not possible at both the receiving and delivery locations. processing methods, i.e. moving the reel to precisely defined positions or The pallet must be placed on the pallet at the delivery location and the reel must be placed on the pallet. They must be arranged in a way that allows them to slide to the same position. this child This means that multiple receiving and delivery locations can be provided in one system economically. This means that expenses will increase.

According to German Patent Application No. 35 32 172, spinning cans are conveyed. Unmanned transportation system control is known.

In this case, vehicle control is carried out in constant communication with a central control unit. central computer The data is used to control the transport vehicle to ensure arrival at the card, acceptance of cancer at the card, Signals inform the transportation run from the card to the draft and the unloading of cans at the draft. let The transport vehicle therefore processes commands for movements each time. After executing the command The vehicle is ready again for the next command. The disadvantage of this method is that the central High workloads must be accomplished with computers monitoring all transport vehicles in operation. In this case, there may be a waiting time for the transport vehicle when receiving the order of law. It is.

The object of the invention is therefore to provide a variable, cost-effective and quick method for transporting cargo, especially for the textile industry. The crab is transported from the receiving point to the storage point where it is unloaded and prepared for reprocessing. An object of the present invention is to provide a method and apparatus for the purpose.

The solution to this problem is clear from the claims. According to the present invention, luck The transport order is sent to a central office that determines the receiving and storage locations and the travel distance thereto. Constructed by computer. This transport command is then sent to the vehicle from the central comviator. The reception of the cargo to be transmitted to the computer unit of the vehicle and subsequently transported by the vehicle is processing and storage independently. In this case it is advantageous that during the processing of transport commands the central There is no load on the computer. Only when the command is fulfilled will the vehicle be sent to the central computer. Inform Ta.

While doing so, the central computer configures transport commands for other vehicles. or have the capacity to control other equipment in the facility. maximum depending on the vehicle Only when the transportable number of cargo is prepared, a transport command is configured and sent to the vehicle. It is advantageous to be able to do so.

transmission of data of transport orders and/or configured for this purpose to a central computer. The response of the vehicle during the part of the trip that was interrupted causes communication between both computers. It is possible that the device is necessarily installed exclusively in a part of the running section provided for this purpose. It is done profitably. On the other hand, in special cases, for example in the case of a breakdown, the vehicle's computer unit communication with the vehicle's central computer or vice versa is independent of the vehicle's respective location. It may also be advantageous to be enabled.

In this case the vehicle can receive new commands from the central computer.

In driving sections with branches, vehicles signal the branching position of the driving section in response to commands. Advantageously, a signaling device is provided for the notification. When the vehicle approaches a fork , the vehicle is stopped briefly before entering the junction. The vehicle then receives a light signal, e.g. Dark or visible, e.g. approach-departure, to indicate in which direction the branch should be set. . A similar circuit can also be used to ensure that the curve area is clear from the vehicle in front, even before the curve. It is effective to ensure that While the vehicle is stationary within the curve area, the following vehicle Entry into the curve area is prevented by the influence on the drive.

Separate receptacles are provided for the storage of different types of reels or reel-like goods in the textile industry. A designated storage location is assigned to each location. Cargo transported by type storage Advantageously, a second process of sorting the cargo for reprocessing can be avoided. subordinate This saves money and time. In this case, cargo is subject to changes in process, size, shape and/or Or sorted according to quality. This sorting is also used to protect cargo during cargo acceptance. This is also done for pipes.

The challenge is to create a cargo transport system with at least one vehicle to receive, transport and store this cargo. The problem can also be solved by transportation facilities that transport items from receiving locations to storage locations. transportation A feature of the facility is that data containing information on transportation orders is stored in a central computer. from the computer to the vehicle's computer unit and to the vehicle's computer unit. It is equipped with a device that autonomously and actively processes transport orders. So the car Both systems allow transport commands to be executed without further contact with the central computer. , including all equipment. Precise parking for handling cargo to be transported All main equipment for controlling the location is included in the vehicle.

The set task was to create an electric overhead vehicle equipped with a device that processes transport commands. This problem can also be solved by a load conveyor. The vehicle has a computer that communicates with the central computer. drive, control, branch position and handling of the computer unit and the cargo being transported. Equipment is in place for this purpose. If the processing equipment is driven by energy, the vehicle A compressed air generator is also located.

An electric overhead conveyor transports reels or reel-like cargo. If the processing equipment is A gripping device with a grinder is arranged. The reel advantageously runs approximately horizontally and It is transported horizontally. The gripping devices can be controlled independently of each other. Then, the cargo can be received at various receiving points and/or at various storage locations. Can be stored in a pipe location. A particularly careful reel treatment method can be achieved as follows. . That is, the width of the opening of the gripper is made variable by guiding it in a parallelogram.

In this way, a large frictional force is applied to the reel or the thread wound around the reel. Cannot be added.

In order to avoid dropping the transported cargo and secure the reel in the event of an energy failure, the reel is Sand suspending mechanical closure device.

Further advantageous embodiments of the invention are evident from the claims.

Next, the present invention will be explained in detail using figures. Example is electric overhead conveyor Regarding. However, in a similar way, the operation of an unmanned transport system as an example of transporting spinning cans is considered. Transport vehicles are also included in the present invention.

FIG. 1 schematically shows the configuration of a reel transport facility. Starting points 1.2.3.4 and 5 A reel or reel-like cargo is created. The starting point for this is the spinning machine, the reel machine. or similar machinery on which this type of cargo is manufactured or prepared. be done. Hereinafter, this cargo will be referred to as the reel 2o.

Starting points 1.2.3.4 and 5 with target points 10, 11.12.13.14 and 1 5 is compatible. This target point can be, for example, a transport box, a small pallet or a holding area. In the meantime, the next processing of the reel 2o is performed. Both the starting point and the target point are group 30. 31 may be mutually arranged.

This is advantageous when different qualities of the reel 2o are produced at the starting point. group The division into 30 and 31 allows the reel 20 to be stored by type. This thing is , in the embodiment of FIG. 1, the reel formed or prepared at the starting point 1.2 or 3. 2o is arranged at target point 10111 or 12. The next distribution is as follows. It is done in this way. That is, in group 3I, the reel 20 at the starting point 4 or 5 is Target points 13, 14 or 15 are supplied.

As shown in the example of group 31, multiple target points are distributed to a certain number of starting points. This is often advantageous. In other words, one of target points 13, 14 or 15 is defective. More advanced types provided for the reel or alternatively provided at the starting point of purity can be achieved.

If the target point is placed on the circumference of a defective reel, or if the reel does not meet the required quality. It's always brought here. Therefore, a classification dependent on the quality of the reel is ensured. Become so. A variable number of starting and destination points results in a very large number of turns at the starting point. It is also advantageous if the frame 20 is manufactured. A larger number of target points can be prepared. This causes the currently full reel container to be replaced with an empty reel container at another target point. Even when exchanging vessels, one target point is guaranteed to be free at any time. roll Types of reel Purity is related to quality and also to the shape of the reel. Cylindrical for various starting points Once the conical or conical spool 20 has been formed, this spool is sent to various destination points. must be The same applies to bobbins 20 of different diameters. Of course It is also possible to associate fewer target points with a fixed number of starting points. This thing is , when a few reels 20 are formed per unit time at the starting point, or when the target There is only a small amount of storage space compared to the point, and there are few characteristics in the purity of the species. It is advantageous when the remaining characteristics of the reel 20 are not a measure of differentiation. multiple By consolidating a number of starting points into fewer target points, the required floor space at the target point can be reduced. In addition to the area and small number of devices, the following logic is also advantageously simplified. it's only a little This is because only certain target points are wasted.

In the configuration shown schematically in FIG. Branching can be performed using a plurality of branching devices 41 at the same time. Travel section 40 is fixed It is attached to and suspended without distinction. This running section has a slight incline. Straight and curved running rails 47, which can be assembled even between different arrangements Consisting of pieces. It is also possible to integrate a vertical conveyor into the running section system. Ru. In a preferred embodiment, the running track 47 is a standardized electric overhead conveyor. Consists of expressions. The traveling rail 47 is connected to multiple planes by a vertical or diagonal conveyor. It is possible to place it in This is advantageous for warehouse operations that save space. . The curved sections of the track 47 can be bent horizontally or more or less vertically. Running The unit system-like embodiment of section 40 allows the starting point and target point to be determined in an optimal manner. extremely flexible adaptation of the driving section 40 to a driving course adapted to the location of Is possible.

At the preparation point 42, the electric overhead conveyor vehicle 7 takes over the transport command. I'm waiting for you. Front row section of a series of electric overhead conveyor vehicles 7 A vehicle 7 that has not received a command from the central computer 6 receives a transportation command from the central computer 6. and receive it. The transport order contains the corresponding information regarding the starting point and the destination point to be reached. Regarding the travel section to be passed with junctions and the starting and target points of the vehicle 7 Contains specifications regarding the exact stopping position at. Combiator unit of vehicle 7 As soon as port 72 receives the command, it begins processing the command. For this purpose the vehicle is Travel to the starting point where 20 is waiting, store the reel 2°, and move it to the planned target point. It is then delivered there and returns to the preparation location 42 again. Here vehicle 7 is Line up behind the row of electric overhead conveyor vehicles 7. The vehicle is equipped with a branching device 41. A device is provided for switching to the required position each time. This switching device is suitable This transmitter is an infrared transmitter, and this transmitter makes it possible for the transport vehicle to use a branching device. A signal for switching to the position to be switched is supplied to an infrared receiver provided in the branching device 41.

The branching device 41 of the running section 4o is connected to the preparation point 42, starting points 112.3.4 and 5. and target points 10, 11, 12, 13, 14 and 15, as well as travel section 4o. Significantly, it is recorded on a central computer. When determining transport orders , the salient points to pass are selected and the vehicle to be carried out at one salient point. 7 actions are entered in the transportation order. That is, for example, if the branching device 41 is installed at the branching point, starting point l is ignored, and starting point 2 has to be It was decided that the machine would be stopped to receive the reel. Vehicle 7 records in transport command When driving over unobtrusive points, the combiator unit of vehicle 7 must 72 determines the error by a reasonable test. Transport command or computer Depending on the reaction agreed upon in the data unit 72, it is possible to This means that the vehicle 7 travels in a traveling section and blocks other vehicles 7 in this section. It is something that can be stopped. In such secondary sections, vehicles and people It will be checked and the cause of the error will be removed.

The line of vehicles 7 at the preparation position 42 is arranged until the vehicle 7 at the front receives the command and departs. As soon as it does so, it advances to the frontmost position of the ready position 42. This advance is arranged on vehicle 7. It is initiated by the collision safety device installed. This collision safety device is located in front of the vehicle 7. react to obstacles present. Vehicles 7 behind the frontmost vehicle 7 are placed in front of it each time. A certain vehicle 7 is faced as an obstacle. Therefore, they are prevented from continuing.

The frontmost vehicle 7 is placed on a traveling rail 47 that can be passed only by the obtained transportation command. It is braked by the marked mark. Collision safety devices are mechanical or electrical proximity switches. , acts on the drive device of the vehicle 7, and stops the vehicle 7 when an obstacle is encountered.

Target points 10, 11, 12, 13, 14 and 15 in this example have loading roller controllers. conveyor is located. The advantage of this is that as soon as the transport container is filled, The container 51 can be quickly replaced. Other advantages of loading roller conveyor''? 50, the conversion points can be integrated in a simple manner. This thing is a cone It is particularly advantageous if the reel 20 is organized. It is the reel layer inside the transport container 51. can be arranged in each case in the opposite conical direction. So the place is completely reeled As soon as it is filled with 20, it is possible to convert the transport container 51 to 18σ. Ru.

At the starting point, the reel 20 for reception by the vehicle is immediately below the gripping device of the vehicle 7. Prepared as in. Advantageously, these reels are arranged close to the starting point. step conveyor bell) on top of 100. The spacing between the reels is Corresponds to the spacing between the grippers of the gripping device, but depends on the length of the sleeve. The reason is volume This is because the sleeves projecting beyond the windings of the frame 20 collide with each other.

In this case, a part of the circumferential surface of the reel 20 is above the step-conveyor belt 100. . This arrangement of the bobbin 20 has the following advantages. That is, the spacing is relative to the reel. Regardless of diameter, without the need for additional equipment to maintain precise spacing, The same is true in either case.

The traveling section 40 is divided into various closed sections. For example, the block section is one car. starts after the curve and ends, for example, before the next curve. of the start and end points of the blockage section Other elements within the running section 40 are located in receiving or storage areas and in branching devices. be. The individual closed sections can be powered independently of each other. This creates a risk of collision. When there is danger, it is possible to prevent the vehicle from reaching a dangerous position within the travel zone 40. can. For example, if a vehicle is in a curve, any vehicle following it will also be in the curve area at the same time. cannot enter the area.

Both vehicles 7 thus collide with each other in the curve area due to insufficient collision protection. collision is prevented. In the branching area, the vehicle is opened by controlling the blocked section. This prevents the vehicle from entering the diverter device and falling. The vehicle controls the blocked section. As soon as the critical blockage section is reached, the current in the previous blockage section is interrupted. be called. Thus, the preceding vehicle 7 leaves the critical blockage section again, and the vehicle that fails to do so The driving of the vehicle 7 is interrupted until the closed sections of both vehicles 7 are connected to the power supply again.

In the reel transport facility shown in FIG. Data transmission is done by infrared radiation. At the preparation position 42, the vehicle 7 is in the waiting position. First of all, there are no instructions. The reel conveyor belt at starting points 1 and 2 is always Run at the time. The starting point here is a rotor spinning machine. reel conveyor belt , for the reel changing process at the individual spinning stations and also for the winding of the wound reel. It is only stopped to load the frame onto the conveyor belt. reel conveyor The belt opens onto the step conveyor bell I-100 on the front side of the rotor spinning machine. ing. The four reel frames are the step conveyor belt lo.

As soon as they were gathered in the central computer, a retrieval signal was prepared for the exam on the central computer. There is. The central computer 6 uses the Boring method to remove the reel 20 from the starting point. Inquire at the starting point whether or not it has been prepared for. The Boring method is a reeling method. 20 is present for retrieval or not. . Furthermore, the central computer 6 corresponds to an electric overhead conveyor vehicle 7. Prepare notification of transportation demand for rotor spinning machines to the directive.

Depending on the accuracy of monitoring for each type of reel 20, the configuration entered into the central computer This recognizes which materials of which quality are produced at each starting point. type species If you try to maintain the separation more precisely, the display of the individual reels will be detected at the starting point. and sent to a central computer.

Therefore, the transportation command is organized depending on the type.

The reel at the starting point is detected by the central computer and then the best adapted The target point is determined at the central computer. To determine the target point, use the reel Depending on the quality or type, it may also be carried out by the shortest and therefore fastest possible route. be called. In the embodiment of FIG. 2, the two starting points l and 2 correspond to the target points 10 and and 11. The double-edged target points 10 and 11 are in this example the loading loco. -ra conveyor 50, in which empty transport containers are fed from one side to the changeover position. and the filled transport container is delivered on the other side of the loading roller conveyor.

Sensors 110, 111 are installed on the loading roller conveyor 1 or 2.

112 or 210.211.212 are arranged. Sensor 110 or 2 10 identifies whether there is a stock of empty shipping containers. This is not the case As soon as the current transport container is filled, the respective target points cannot be considered. Sensor 111 or 211 is located on the loading roller conveyor. It is located in the conversion position. This monitors the actual position status of the turning device.

The reel 20 is stacked one above the other in a conical reel transport container, and a conical reel is formed by laminating many layers. For storage, if one layer is completely filled in the transport container, there will be 18 conversion points. Rotated by σ. In this way, the transport container is evenly filled with the conical spool. be able to. Sensor 112 or 212 indicates that loading roller conveyor 50 is fully loaded. Identify whether the transport container has a capacity greater than 5. sensor 112 Or if there is a fully loaded transport container at 212, the respective target point is the transport container. There is no longer any room for consideration of the directive.

At the beginning when the loaded fully loaded transport container is removed from the loading roller conveyor 50. This buffer area can accommodate other fully loaded containers at the diversion point. be.

As soon as a suitable target point has been determined by the central computer 6, the next The position to be placed is determined.

The position is advantageously based on the determined filling pattern.

This pattern is detailed in FIGS. 14 and 15. This determination of the next position Has a point. In other words, it is only necessary to change the stopping position of the vehicle 7, and the transportation capacity There is no need to move the container to various positions. Furthermore, in transportation commands, the central computer - According to Taro, what should be the storage direction for the conical reel 20? It is decided how. As already mentioned above, this means that the new conical reel 20 It depends on the position of the conical reel 20 in which the layer is to be placed. have opposing cone directions When the layers of two reel frames overlap, a generally vertical stacking of the reel frames 20 is performed. be called. Furthermore, depending on the implementation of the reel transport facility, the changeover point can be moved to the correct position. or in which direction the conical reel in vehicle 7 should be oriented. is determined in the Directive.

After associating the target point with the starting point, a set of data for transport commands of the vehicle 7 is organized. Ru. This data is then sent from the central computer 6 to the vehicle 7. This is In this embodiment, this is done via an infrared transmitter 61. Vehicle 7 has an infrared receiver. is provided, which transmits the data to a computer unit 72 of the vehicle 7. child The data indicates the internal travel course for the vehicle 7. Computer unit of vehicle 7 After the command is received by the vehicle 72 and the vehicle 7 departs, a decision must be made. At each position in the travel section 40 where there is no vehicle, this position is compared with the internal travel course.

This orientation of the vehicle 7 determines how the vehicle should react. . The reaction consists in the storage of the reel 20, the storage of the reel 20 or the switching of the branching device.

Three different types of flags are fixed to the running track 47. This is the sync flag 43, a counting 7 lag 44, and a zero flag 45. The vehicle 7 has an initiator 71 is located. This initiator 71 responds to flags 43, 44 or 45. do. The vehicle 7 passes the synchronization flag 43 for the first time. This allows the vehicle All counters within are set to zero. By doing this you will get the wrong start reaching a point or target point is avoided.

one meter before each starting point l or 2 and before each target point 10 or 11. A number 7 lug 44 and a zero flag 45 are arranged. These flags indicate that vehicle 7 from the vehicle 7 unless it is at a starting point or corresponding target point suitable for processing the command. is ignored. Vehicle 7 reaches the starting point specified in the command and passes count flag 44 Then, the initiator 71 causes the drive device of the vehicle 7 to reduce the traveling speed. A signal is emitted. This advantageously allows precise positioning at reduced travel speeds. It is ensured that the braking distance is small enough to reach . Reached count flag After that, the vehicle reaches the zero flag 45 at a reduced running speed.

The vehicle 7 is at the starting point 1 or 2, where the delivery position is always the same at any time. If so, the vehicle has stopped exactly at the zero flag 45. In vehicle 7 , a gripping device is arranged which is lowered to the level of the prepared reel 20. grab device The machine captures the prepared reel 20 and lifts it to overhead height. grab As soon as the device is again at the level of the vehicle 7, the vehicle is again set forward at maximum speed. The vehicle then travels further to the specified storage position. A branching device 41 is arranged on the driving course. Then, the instantaneous position of the vehicle is accepted via the initiator and the computer of the vehicle 7 Evaluated by data unit. If the branch device 4 is not in the required position, turn off the vehicle. The branching device 41 is set via the signals sent from both 7. Vehicle 7 is set When it reaches target point 10 or 11, it passes the counting 7 lag 44 again. This reduces the transport speed. Subsequently, the zero flag 45 is passed.

The exact storage location within the transport container may change when storing the reel, so transport instructions may vary. The exact distance from the zero flag 45 to the storage position is determined in the order. vehicle A summing counter located at 7 counts the number of rotations of one support roller of the vehicle 7 and thus Determine the length of the route section traveled. If you drive along a route that has been set in advance, , the vehicle 7 is stopped. The gripping device with the reel is lowered and the gripping device It is removed from the frame and then sent up again to the height of the vehicle 7. Vehicle 7 processes the command After that, the vehicle returns to the preparation station 42, where it waits for updated commands. vehicle 7 through the initiator 71, the passed position cannot match the internal command. or the reel 20 cannot be loaded or unloaded, or If another error is confirmed during the transport order processing, the transport facility configuration will be changed. It is advantageous if there is a subsection into which the vehicle enters. Do it like this What is ensured is that the implementation of other vehicle 70 commands is not inhibited. The mistake is The affected vehicle 7 is then inspected by a person to find out the cause of the error. Ru.

The number of vehicles required per transport facility is determined by the number of rolls produced per unit time and the number of vehicles run per unit time. Determined according to the length of the row course. in a facility with 10 rotor spinning machines. Generally speaking, the optimal ratio is between 2 and 5 vehicles, i.e., when the machine is disposed of at the right time. Minute and efficiency optimization is achieved.

When the vehicle 7 reaches the preparation point 42Vc, the command from the central computer 6 is received. take over. This enables the vehicle 7 for the next command.

Target point control by intelligence present by computer unit 72 in vehicle 7 It is possible to implement

This means that the vehicle 7 has a fixed target and a route to this target itself. It means that they are communicating.

It is therefore possible to transport it to a suitable position in front of the branching device 41. Driving section 40 is divided into closed sections in this case. This blockage section can be tracked by individual vehicles 7. This is the part that cannot be overcome. One of the vehicles 70 has a malfunction, and as a result, vehicle 7 Run #! When it is no longer possible to A signal is sent, this signal is evaluated by the central computer 6 and a new command field is sent. Consultation will be given. Therefore, it is difficult for other vehicles 7 to enter this blocked area. is not possible and these vehicles must detour around the blocked blockage. 0 The initiator 71 of the vehicle 7 responds to the flags 43, 44 and 45. Synchronous hula One initiator 71 has jurisdiction over each flag 43 and zero flag 45. During this period, two initiators 71 are provided for the counting flag 44. There is. When the synchronization flag is passed, all counters in the vehicle 7 are set to zero.

The zero flag 45 sets the travel measurement to the value zero, so that the vehicle 7 does not advance from the zero flag 42. Measure the distance.

The counting 7 lag 44 sets the counter in the computer unit 72 of the vehicle 7 to the value "" increases by l'. In this way, the computer unit 72 The number of passed conspicuous points in 40 is counted. The counting flag 44 indicates that the determination is They are placed at 400 points in the driving section that must be completed. This means for example This is an example of a starting point, a destination point, and a branching device. At the starting point and the destination point The switching device The branch state is determined at . Therefore, in the transportation command, the number of items passed It is determined what will be done by the vehicle 7 at the standing point. Therefore reel transport facility What is important for trouble-free and reliable operation is that the count of count flag 44 is correct. It is the right thing to do. For this reason two initiators 71 count 7 lag 4 4 is installed on the vehicle. Both initiators 71 are connected to the vehicle 7 have passed different count flags 44 or the same count 7 has passed due to vibrations, for example. The computer determines whether the initiator 44 has sent multiple counting pulses to the initiator 71. As recognized by the data unit 72, they are interconnected. In case of vibration, The shiator 71 may pass the same counting 7 lug 44 multiple times forward and backward. Ru. With the connection of both initiators 71, the forward passage of the counting flag 44 is now controlled. The counter will now advance by 1 when passing backwards, while the counter will advance by 1 when passing backwards. This will allow you to reduce the As a result, each count 7 lag 44 is counted only once. .

The use of flags 43, 44 and 45 is advantageous because of these simple passive components. Vehicle 7 is now actively controlled by computer unit 72 . this A particular advantage achieved by It is extremely flexible in terms of If an additional counting flag 44 is placed, New starting points and destination points can be added to existing facilities at little cost; Active parts of the vehicle 7, which are more complex than flags, cannot be changed.

Figure 3 shows optical data transmission from the central computer 6 to the vehicle 7 by infrared radiation. vinegar. For this purpose, the system is divided into a moving part for facility control and a stationary part. Facility system The movable part of the control is the computer unit 72 in the individual vehicle 7.

The stationary part of facility control is the central computer 6. central computer 6, The starting and goal points used via the personal converter and the individual An input is made of the reel quality present at the starting point or at the target point. different outputs It is possible to handle completely different cargoes at the point of origin. Thus, the present invention With the conveying facilities of It is possible to process Therefore, various target points must also be defined. do not have. Similarly, this flexible method provides an advantageous way to accommodate frequently changing personalities. It is possible to newly define a starting point using a personal computer. starting point and Input of new parameters for the target point is done by computer.

The data is prepared for conversion into a signal that can be evaluated via the bus module 82. Ru. Data transmission takes place in full-duplex mode, i.e. Data can be received and transmitted by both moving and stationary parts of the control. be done.

The stationary part of the facility control is equipped with an infrared transmitter 61 as well as the movable part of the facility control. and an infrared receiver 62 are arranged. The infrared transmitter 61 in the fixed section is for facility control. to the infrared receiver 62 of the movable part. Similarly, from moving parts to stationary parts of facility control The reverse is true for data transmission. Therefore, infrared rays can be applied to both moving and stationary parts. A transmitter 61 and an infrared receiver 62 are arranged. Data transmission distance is 200 Progress is made to reach m. Infrared in the moving parts of the facility control, i.e. in the vehicle 7. The signals received via line receiver 62 can be used to control storage programs in vehicle 7. transferred to a capable control unit. This storage program control unit is a controller of the vehicle 7. computer unit 72. of the accumulation program through the received signal Variable parameters are set. This parameter includes the receiving and sending points. and switching points of branching devices.

Displays necessary for fulfilling the directives, each of which is different, are determined. As a result, vehicle 7 It becomes possible to perform command processing that is controlled by the turning point of the opposing eye.

A control unit 81 capable of controlling the accumulation program of a stationary unit for facility control is placed at a target point, for example. has been done. The loading roller is The position of the rotary plate on the belt conveyor is controlled. The central computer 6 is The control unit 81 that can control the storage program controls the storage program of the movable parts of the facility control. Similar to that in the controllable control section 72, the influence depends on the commands to be prepared. Boss. The storage program forming the computer unit 72 of the movable part is controllable. Differences between the control unit and the stationary unit for facility control with respect to the control unit 81 that can control the accumulation program lies in the possibility of data transmission. Transmission to moving parts must be flexible. In contrast, the data transmission to the control unit 81 that can control the storage program of the stationary unit is by line. It is more advantageous and more economical to carry out the process via a route.

FIG. 4 shows an advantageous alternative configuration for optical data transmission by infrared radiation. central controller As in the case of FIG. connected via. A bus module 82 is arranged at the node. Faith In the embodiment of FIG. 4, in contrast to the embodiment according to FIG. 3, the signal transmission is by infrared radiation. This is done via the sliding contact 73 and the conductor rail 46 instead of via the sliding contact 73 and the conductor rail 46. central computer An electronic signal converter 83 is arranged between the terminal 6 and the conductor rail 46. this signal The converter 83 allows the central computer to communicate with each movable controller. , prepare the data. The conductor rails 46 are completely connected to the individual movable controls or the vehicle 7. accessed via contact 73.

The signals accessed by the sliding contacts in the conductor rail 46 are thus movable. A control unit capable of controlling the accumulation program in the signal converter 83 in the control unit or It is converted into a signal that can be evaluated by a computer unit 72 of the vehicle 7. Individual A signal converter 83 is arranged in each vehicle 7. Therefore, it is especially specified for this vehicle 7. can recognize the received signal.

The embodiment according to FIG. 4 has the following advantages over the embodiment according to FIG. i.e. inside The central computer 6 communicates from time to time with the individual computer units 72 of the mobile control section. It is possible. In the embodiment of FIG. 3 this is the central combinator 6. This is only possible within the area reachable by the infrared transmitter 61. Figure 4 fruit Embodiments offer particular advantages in the event of a failure of a movable or stationary element of the facility. the upper level There are advantages associated with the storage location 42.

In the embodiment shown in Figure 4, multiple preparation locations can be set up without requiring additional costs. Therefore, it is possible to arrange the vehicles 7 uniformly throughout the entire transportation facility, but as shown in Fig. In such embodiments, additional infrared transmitting stations must be installed. All transportation The advantage of uniform distribution of vehicles 7 across the facility is that individual outputs are It is possible to keep the arrival route of the vehicle from the starting point extremely small.

FIG. 5 shows the vehicle 7 on the running track 47. The running track 47 is preferably made by German engineers. With running rails for electric overhead conveyors according to association guidance guidelines 36437C1 be. Similarly, the drive unit 74 and traveling frame 75 are connected to an electric overhead conveyor. It is a well-known element of the Y-type. A sliding line is provided on the running track 47 for current and data transmission. are arranged in a known manner. This sliding line is not shown in FIG.

Depending on the length of the vehicle 7, two or more support rollers as well as several lateral supports A traveling frame 75 made of rollers accommodates a suspension section 76 at a lower receiving position. Ru. The suspension section 76 is generally an element for generating compressed air, controlling the winding frame, and processing the winding frame. Consists of. A computer unit 72 is installed on the suspension section 76 to control the vehicle 7. It is placed in a switch box 310. This switch box 31 0 includes a control unit capable of controlling the storage program and a signal converter 8 depending on the embodiment. 3 is placed. If the data transmission is carried out by optical means via infrared radiation , the computer unit 72 transmits the signal to an infrared receiver provided on the suspension section 76. The receiver is picked up via the transmitter 62. Data is transferred from computer unit 72 to a central computer. An infrared transmitter 61 is likewise arranged on the suspension 76 for transmitting to the data controller 6. . Advantages of arranging the infrared receiver and the infrared transmitter 61, 62 on the suspension part 76 The point is that the area below the running track 47 has the least number of obstacles. optical decoding For data transmission, visual inspection is required between the transmitter and receiver to ensure data transmission. International communication is necessary.

Generally, the upper area of the running rail 47 is a suspension area of the running rail 47 that is a hindrance to visual communication. The racking equipment is running. If the running rail is supported by the bottom support, the running rail 4 7 in the vehicle 7 is advantageous. The reason is that in this case the running rail 47 This is because failures on the lower side of are more frequent. Further, the traveling frame 75 has an initiator. 71 is arranged. This initiator 71 places it on the running rail 47. The selected switching flag is recorded. Initiator 71 is a computer in the switch box. It is connected to the data unit 72.

The traveling frame 75 is connected to the crossbeam 300 of the suspension section 76. Therefore, the running rail 47 It is guaranteed that horizontal and vertical curve driving is possible. Suspended on crossbeam 300 The portion 76 is immovably fixed. There is a pressure tank along with the switch box 310. A compressor having a compressor 320 and a processing device 330 are arranged. pressure tank 320 is fixed to a support 321. Processing device 33 not shown in FIG. The drive for 0 and the compressor 325 are fixed to the support 321. processing equipment 330 is composed of a plurality of gripping strings 332 arranged across the running direction of the vehicle 70. Then it is advantageous. Due to the arrangement transverse to the direction of travel, it is advantageous to accommodate the reel and Storage can be carried out with very little expense for the arrangement of storage areas and storage areas. I'm going to growl. As a result, an extremely cost-effective and flexible transportation system has been achieved. will be accomplished. Another advantage lies in the short overall length of the vehicle 7 achieved thereby. vehicle Since the length of the vehicle 7 does not directly influence the minimum radius of the running track 47, the shorter length of the vehicle 7 It has a long overall length.

It is advantageous. Vehicle 7 is also 1. The shorter the crossbeam 300, the easier it is to realize a narrow curve. can be easily adapted to the building layout or facility layout. . If the length of the vehicle exceeds the maximum value, the suspension section 76 is configured by a hinged connection and this This results in a loss of stability, which is compensated by the additional carriage 75. So By arranging the upper operating device 330 laterally with respect to the traveling direction, the suspension section 7 It is certainly possible to freely adapt the number of gripping devices 332 without deforming the become capable. Therefore, it is possible to install, for example, 3, 4 or 5 sets in a vehicle without requiring large additional costs. A set of gripping devices 332 can be provided. However, the operating device has four sets of gripping devices. It has been found advantageous to place 332. This advantageous number allows the reel to be stored This is manifested by frequent use of standard transport containers. This can be done as follows It is done. That is, four reels 20 fit into the transport container in a line with their width. Do it like this.

The gripping devices 332 are flexibly connected to each other so that they can move in a parallelogram shape. tied together. Therefore, relative motion acting on the winding frame 1C can be avoided. to this This allows for extremely careful handling of the reel. The reason is that the gripping device 5: This is because it is always positioned vertically and grips the reel from below without any rotational movement. Ru. When grasping the winding frame, the individual winding threads may be pulled forcibly. The twisted thread may be worn out. Other advantages of this type of movement of the gripping device are , the space required on the sides of the catch device 332 for gripping and releasing the reel is extremely small. That's a certain point. This requires extremely high packaging density, especially for the reel. Appears in the case of a large transport container. If the gripping device protrudes across the width when the reel is released, The spacing relative to the transport container wall or the next spool is determined by the distance between the adjacent spools of the gripping device 332. must be extremely large to avoid contact with the The gripping device 332 is Controlled by compressed air. The gripping force of the gripping device 332 depends on the pressure of the compressed air. Adjustable. As a result, the reel with a small reel density can be collected with a small gripping force. This ensures that damage is avoided.

The gripping device is arranged such that the reel is gripped with its recesses. The axis of the reel is approximately Arranged horizontally across the direction of conveyance. The advantage of this is that inside the transport container On the one hand, a high packing density is achieved and on the other hand, the reel rotates only slightly. That's a very good thing. In the same way that the reel is positioned within the transport container, These reels are frequently not captured by the device and are It should be able to rotate to the correct position instantly. As a result, there is less risk of damage to the windings. Careful handling of the frame is possible in an advantageous manner.

The operating device consists of individual gripping devices, in this case one set of gripping devices 332 for each field device. is located. Therefore, the reel of each chapter is individually grabbed by a set of grippers 332. captured.

Depending on the type distinction to be achieved in the storage area, all gripping devices in one operating device can be configured so that they can be controlled commonly or independently of each other. Become.

To achieve a high degree of species purity, each individual gripping device is individually controllable. That's advantageous. Since there are different types of K, they are compatible with other reeling frames of transportation instructions. The possibility of transporting individual reels to other destination points is provided. that high species °C where purity is not required or the reel has already been sorted into the receiving area. If so, all the grabbers 332 of one vehicle 7 are opened and closed simultaneously.

This possibility makes the control outlays lower 1-1 and also the mechanical outlays lower.

The force of gripping the reel, which depends on the reel density, is controlled by a valve that regulates the air pressure in the gripping device. Adjustable through. For careful gripping of the gripping device on the reel, the gripping force is Besides, it is equally important to adjust the gripping speed of the gripping device. Grasping device Reducing the gripping speed of the It is regulated through a diaphragm that regulates the amount of compressed air. Grasping of the gripping device against the reel The lower the speed, the more carefully the reel is gripped. Because grasping machine 332 is braked by the winding of the reel, so the winding load at low speeds is relatively low. This is because it is less than at high speeds.

Regardless of the gripping force and gripping speed of the gripping device, the gripping device shown in FIG. It is possible to grip reel frames of various diameters. The gripping devices are arranged in parallel in the running direction. and the winding rod shafts are aligned generally transversely to the direction of travel and aligned with each other, i.e. In other words, by arranging them so that they are lined up across the running direction, the space between the reel frames can be reduced. The distance is always constant. This means that bobbins with different diameters have the same side surface requirement. It represents having a place. The maximum reel diameter is the maximum diameter of the gripper 332. Limited only by the large gripping width, but also by the spacing between the gripping devices Not done.

The switch box 310 is advantageously arranged at the end of the vehicle 7. This switchboard The box is closed via a cover 311. Lower part of switch box 310 Maintenance work is easy due to the location. Since the cover 311 can be flipped up, the unobstructed by the converter unit 72 or the control unit that can control the storage program. Access is well guaranteed. In addition, the switch box 310 has a coupler. It is located. It is possible to connect a manual control device to the vehicle 7 via this coupler. It is Noh. A manual control device allows the starting point to be changed, for example in the event of a failure of the central computer 6. It is ensured that the removal is carried out under manual control. Check the operating ability of vehicle 7. , or when attempting to drive the broken vehicle out of the driving zone 40. Manual control is also advantageous when For manual control, the movement of the vehicle 7 and The movement of the gripper 332 or the lowering of the operating device 330 is manually controlled.

A drive unit 74 is responsible for the movement of the vehicle 7. Motor 741 connects transmission device 742 The drive roller is connected to the drive roller through the drive roller. This roller rolls on a running track 47.

Manual sliding operation is possible via a mechanical connection in the transmission 742. Vehicle 7 In the event of a power outage or control failure, the operator must activate the mechanical coupling device. The vehicle 7 can be pushed out onto the side track by manual sliding operation. on the side track The main section of the facility will not be blocked. This leaves unimpeded reel transport. This will continue to be carried out by the existing vehicle 7.

For guiding the receiving and storage locations ((switching flags are placed in the travel section) . Two flags are provided for each stationary point. At the first flag, the motor – The speed is reduced from fast to slow. The role of the second flag is that its predecessor was the central controller. The route section defined by the computer 8 is measured until it reaches the stopping point.

An increment measuring device 75] is provided for accurate route section measurement, and this device are arranged on the non-driven rollers of the carriage 5. Increment measurement device 75 1 counts the revolutions of the undriven roller, in which case the process that has proceeded can be inferred. be measured. The rollers generally slip because the rear rollers are not driven. Start running without a problem. This allows extremely accurate route section measurements. measured The determined route section is transmitted to the computer unit 72, which results in the planned route being After reaching the section, a signal is sent to the motor 741, which stops the vehicle 7.

The pressure tank 320 is connected to the operating device 3 via a helically wound compressed air hose 322. It is connected to 30. The spirally wound compressed air hose 322 Advantageously, snagging of the compressed air hose 322 during movement of the operating device 330 is prevented. Ru. Moreover, the spirally wound compressed air hose 322 is connected to the operating state of the operating device 330. In this state, the vehicle 70 does not hang downwardly from the lower edge of the ridge. As a result, vehicle 7 The risk of snagging the compressed air hose while driving is prevented. Suspension of operating device 330 In order to achieve as space-saving an attachment as possible to the section 76, The base 322 is attached to the operating device 330 via the swinging portion 323. compressed air hose 322 is open in the swinging part 323, but this swinging part itself is connected to the operating device 330. It is attached to the upper joint 324 of the. When the operating device 330 is in the raised position, it swings. The section 323 is folded flat on the upper side of the operating device 330. Operating device 33 In the extended state of 0, the swinging portion 323 is folded upward via the joint 324. brought to the specified position. By doing this, the reel can be stored in the transport container. When doing so, you no longer need additional lateral space for insults. This allows the inside of the transport container to A high packing density of the reel is guaranteed.

In order to receive the conical reel, the gripper 332 is rotated in each case about a vertical axis. In this way, the gripper 332 can hold the reel as much as possible. This ensures that the grip is carried out on a larger surface. By doing this, the reel Surface pressure on the winding can be minimized. The center is moved by operating the gripper 332. The state of the conical direction of the reel captured by the sensor is detected. individually in vehicle 7 Since the embodiment with the rotatable grabber string 332 is in question, this signal It is therefore possible to align the conical reels in the same direction.

Sorting the conical reel into the same position already takes place in the receiving position of the device. If the gripper string 332 is centered on the vertical axis of the operating device 330, It is shown in detail that the conical reel is rotated, thereby reorienting the conical reel. possible in embodiments that do not. By doing this, at the target point The turning point can be omitted. The reason is that it depends on the conditions in the transport container. This is because the correct positioning of the reel has already taken place in the vehicle 7.

If the spacing between the reels is not large enough, it may be difficult to obtain sufficient spacing between the reels. It is necessary for each reel to rotate. This is achieved by the mutually expanding movement of the operating device 330. This is possible through telescopic expansion. For transportation, the reels must be moved relative to each other with minimum spacing. It is advantageous to let This increases the running stability of the vehicle and The lateral space required for the upper vehicle is reduced.

FIG. 6 is a plan view of the suspension section 76 removed from the traveling frame. Figures 7 to 7 The cross section of FIG. 10 is shown in FIG. 6.

A motor 340 is arranged on the support 321 . This motor 340 The height of the mounting 330 can be varied.

Motor 340 is a slip armature motor that is braked with no voltage applied. It's advantageous. In this case, the pressure spring is attached to the motor shaft to which the rotor and brake are fixedly attached. slide. When the voltage is cut off at the motor, the brake is pushed into the brake seat. be pressured. This allows the operating device 330 to be fixed at the instantaneous height in the event of a power outage. will be carried out reliably. In this case, the operating device 330 may suddenly fall during a power outage and may The risk of injury to staff is avoided. Moreover, as a result, the operating device 330 Advantages are achieved when mechanical fixation is provided in its upper position.

As a result, the motor 340 may not be powered during the transportation process. Mo A transmission 341 is arranged on the support 331 and connected to the motor 340 . Transmission gear The rotation speed of the motor is increased or decreased to the desired rotation speed of the roller 334 by the position 341. You can A coupler 342 is provided between the transmission device 341 and the operating device 330. is located. This coupler offers convenient assembly possibilities and adjustment possibilities. bring about. This is because it can compensate for slight axis deviations. be. If an excessively large force is applied to the operating device 330, the coupler 342 will cause the motor 34 to 0 and the transmission 341. Excessive force may cause the operating device to e.g. This may happen to the operating device 340 when it gets caught on an object when it is being pulled.

An increment measuring device 343 is arranged on the shaft leading from the coupler 342 to the operating device 330. ing. This increment measuring device 343 measures the actual rotation of the hoisting device 333. determined. This is advantageous for accurately measuring the instantaneous height of the gripper 332. be. A flexible belt is wound around the roller 334 of the hoisting device 333. A gripper 332 in the frame is fixed to the belt. The thickness of the flexible belt This makes it possible to maintain suspension of the gripper 332 with less vibration. It is proved. A flexible belt is attached to rollers 334. i.e. both It is arranged so as to be guided by the direction change roller 335. The roller 334 rotates Both parts of the flexible belt are then wrapped or unwound.

By doing this, the gripper 332 is moved upward or downward. .

Increment measuring device 334 consists of a metal impeller and an inductive measuring device. The blade is guided A signal is recorded as soon as a passing movement is made at the station. The impeller has many blades. The more accurately the partial rotation of the shaft can be measured. B -2334 The girth of the gripping machine and the thickness of the flexible belt, along with the number of rotations. The actual height is inferred.

FIG. 7 shows a cross section AA in FIG. 6. This side view shows the gripper 332 and the switch. The casing 76 is shown without the box 310. Advantageous in this example Functional unit motor 3401 transmission 341, coupler 342 and roller 3 34 is arranged below the crossbeam 300. By doing this, the vehicle 7 is guaranteed not to be blocked when driving through narrow vertical curves. this place The total height of the joint carriage 75 can be reduced, thus VDI-Guidance Guide 1136 Standard components according to 43/CI can be relied upon. In the display of Figure 7, the buffer vessel 344 can be clearly identified. The buffer 344 gently displaces the end position of the gripper 332. Let me try it. Another advantage of the buffer 344 is that the gripper 332 is always lightly biased in the upper position. It is in a state where a space has been added. As a result, when vehicle 7 arrives, it is possible to run the curve. Shaking of the gripper during running or braking is avoided. The buffer 344 is attached to the gripper 332. Advantageously, they are arranged at the four corners of the support. This allows the required characteristics to be achieved to the extreme. This can be achieved successfully. The bias of the operating device 330 is applied and guided. Other types of spring-buffer systems are, of course, possible which provide end positions.

The pressure tank 320 is arranged under the support 331 in the embodiment of FIG.

Compressor 325 is arranged on support 321 alongside motor 340 . The arrangement of the motor 340, compressor 325, and operating device 330 is based on the vehicle 7. It varies depending on the implementation. The arrangement depends on the weight of the components used.

However, it should always be kept in mind that the weight distribution in the vehicle 7 should be as uniform as possible. Be objective. This means safer running of electric overhead conveyors. Guarantee operation.

The support body 331 is provided with a valve 322 . Through valve 322, the compressor The air pressure acting on the gripper 332 from 325 can be adjusted. Winding due to changes in air pressure The force with which the frame is gripped can be changed. This means that the force can be adjusted depending on the reel density. It is advantageous for The aperture 323 can adjust the action speed of the grasping device make it possible. Through the throttle 323, the air pressure of the compressor 325 acting on the gripping device can be adjusted.

FIG. 8 shows a cross section BB in FIG. 6. A compressor 320 runs on a support 331 placed across the direction.

A transmission 341 is mounted on the support 331 . Increase on coupler 342 A minute measuring device 343 is provided. The increment measurement device 343 measures the increment (not shown). It consists of a measuring device and an incremental transmitter. The incremental transmitter consists of an impeller.

The impeller of this example has four blades. From this K, the roller 334 is driven. The measurement accuracy of % rotation of the axis is achieved. Of course, there are blades with more blades than this. It is also possible to position the vehicle, which achieves a higher degree of measurement accuracy.

Support 331 is fixed to base support 301. The basic support 301 is It helps to stably install the individual equipment necessary to complete the directive. On top of that The basic support 301 provides an orderly and therefore easy to assemble arrangement of the individual components. Make it seem possible. The foundation support 301 is connected to the crossbeam via a centrally located hanging part. 300 IC is installed. Crossbeam 300 is an electric overhead conveyor city It serves as an interface to sales elements.

FIG. 9 shows a cross section CC in FIG. 6. Cross section C-C shows the winding device 333 in more detail. Show in detail. A roller 334 and a turning roller 3 are mounted on the support across the base support 301. 35 are arranged. A synthetic belt 337 is wrapped around the roller 334. To be loosened or unrolled. FIG. 9 shows the roller 334 in its unwound state.

The arrangement of the synthetic belt 337 on the roller 334 is such that it wraps evenly on both sides. K to be loosened or unrolled. This makes the bell made of synthetic materials The symmetrical upward movement and downward movement of the operating device 330 attached to the is guaranteed.

One of the direction changing rollers 335 is supported in a variable height. Synthetic belt 3 37 is loaded, i.e. the operating device 330 is connected to the synthetic belt 337. When freely suspended, the direction changing roll 335 is supported at a variable height. is pushed down to its lowest position. When the operating device 330 moves downward, there is no obstacle. As soon as the synthetic belt 337 collides with the The held redirection roll 335 moves to its upper position, resulting in load relief. then operate switch 336. The load relief switch 336 immediately switches off the motor 340. make it stop. By doing this, the operating device 330 at the receiving location can be The lowering is carried out until the height of the prepared reel is reached and the transported reel is When the frame is transferred, the sweeping device 330 automatically maintains it at the height of the last position in the transport container. It is advantageous to be held.

If the load relief switch 336 fails or the storage or receiving location is For cases lower than the minimum possible descent of 30, synthetic belt 337 A metal body 338 is placed in the distal region of the metal body 338 . As soon as the roller 334 is almost unwound Rather, the metal body 338 passes by the sensor 339, which causes the motor 340 to A signal is generated to stop the The metal body 338 is mounted within a synthetic belt 337. Preferably, they are attached metal rivets. The advantage of this is that When winding the root 337 around the roller 334, the metal body Damage to the synthetic belt 337 wrapped over 338 is prevented.

When the synthetic belt 337 is unloaded, the deflection roller 335 is in position 3. When moved to 35', the load relief switch 336 releases the load and modulates the signal. data 340.

This signal causes motor 340 to stop. The update start of the motor 340 is performed by the computer. is controlled by a data unit 72.

Therefore, the load relief switch 338 only has the function of cutting off the motor 340. and does not have any connection functions.

FIG. 10 shows a cross section DD in FIG. 6. Here, the altitude variable direction changing roller 335 Indicates support status. The shaft of the direction change roller 335 is connected to an index spring 345 at both ends thereof. tied together. The index spring is in a high position with the deflection roller 335 unloaded. be moved to a desired position. By doing this, the load relief switch 336 is operated. The index spring 345 is used when the load on the operating device 330 is reduced. The turning roller 335 is configured to move to the upper position very quickly. There is. As a result, prompt shutdown of motor 340 is ensured.

FIG. 11 shows the vehicle 7 during various positions during the transport process. The figure shows the vehicle 7 at one starting point. The operating device 330 is placed at the height of the reel 20. It's descending. The gripper 332 surrounds the reel 20 around it.

The gripper 332 is controlled by a compressed air cylinder.

A compressed air hose 322 therefore leads from the compressor 320 to the operating device 330. There is. In this case, the swinging portion 323 is slightly inclined upward. Synthetic belt 3 37 is partially unwound by a roller 334. The gripper is at the height of the reel 20. As soon as it reached the reel and hit the reel frame, it was placed on the direction change roll 335. Load relief switch 336 responds and stops motor 340. Following this From the combiator unit 72, the compressed air cylinder in the operating device 330 is activated. This sends a signal to close the gripper 332. The reel 20 is gripped As soon as the synthetic material is captured by the grinder 332, the motor 340 is moved again and the synthetic material A manufactured belt 337 is wound around the roller 334. As a result, the operating device 330 It will be sent to the location shown in the diagram.

When the operating device 330 is in the uppermost position as shown in FIG. It is in a ready state. At this position, the vehicle 7 completes the next transport command. this place The combined vehicle travels from the starting point specified in the transport command to the predetermined target point. . In the position shown in FIG. 12, the operating device 330 is in its most stable position. So In this position, the total height of the vehicle 7 reaching the lower edge of the running rail 470 is minimized. Suppression is ensured. As a result, the risk of collision with obstacles is reduced. It will be done.

FIG. 13 shows the vehicle 7 at the target point 10. The operating device 330 controls the transport container 51. It's inside. The gripper 332 is still gripping the reel 20. Operate as next step The pneumatic cylinder of device 330 is placed in an unpressurized position. In this case, the gripper 332 is No compressed air is applied, so the gripper 332 exerts substantially no force on the bobbin 20. stomach. By arranging the gripper 332 so that it can bend and expand, the side when the gripper 332 is opened is It is guaranteed that the surface area required will be kept to a minimum. The gripping machine 332 becomes unpressurized. After that, a synthetic belt 337 is wrapped around the roll 337. Grasping machine 33 2 is assisted by the shape of the gripper, and the reel 20 can be moved without contacting the adjacent reel 20. It glides smoothly beside 20. In particular, the lift path of the operating device 330 is thus high. The advantageous arrangement of the synthetic belt 337 is advantageous in cases where both synthetic belts 337 The quality belts 337 are arranged side by side on the running rails 47 in the suspension section 76. ing. In an advantageous configuration, the width of the synthetic belt 3370 is approximately 10 cm. this Vibrations during withdrawal and retraction of the operating device are thereby avoided. . The use of only two synthetic belts 337 requires little technical outlay. It is extremely advantageous for This is because especially for stable operation of the operating device 330, 1 This is because two hoisting devices 332 are not required.

Compressor 325 supplies compressed air to gripper 332 .

The compressor is connected in this example via two helically wound hose conduits. and is connected to a gripper 332. Starting from the no-pressure position, both compressed air A first of the hoses 322 is connected to the closing of the gripper 332 and to a second compressed air. The air hose 322 is used to open the gripper 322.

A filter is provided in front of the air supply port and exhaust port of the compressor 320. However, this prevents a high degree of dust generation in the spinning mill.

When the exhaust valve of the compressor 325 is properly arranged, the exhaust air of the compressor 325 is It can be used for cleaning air filters and blowing dust off the running track 47. child Especially in textile mills, compressor 325 and electric overhead This is advantageous since a large amount of dust is generated which adversely affects the functioning of the conveyor.

The advantage of the spirally wound compressed air hose 322 is that the hose 330 to reach the lowest position, and on the other hand the height (raised operating device). The reason is that the space occupied by the housing 330 is small. In this way compressed air Snagging or tangling of the hose 322 is avoided. Other implementations according to the invention In the example, the compressed air hose 322 is in one roll with the synthetic belt 337. To be wrapped or unwound. An advantage of this embodiment is that the compressed air hose 322 Must be handled with care.

The winding of the synthetic belt 337 is advantageously determined by the incremental measuring device 343. It is also controlled by the load relief switch 336. load relief switch 336 is reacting to the unloading of the synthetic belt 336. By measuring the length of the root 336 and winding or unwinding, various Winding can be done by speed. In other words, most of the section to be rewound is faster. Advantageously, it is carried out at a fast speed.

Shortly before reaching the predetermined unwinding length, the synthetic belt 3370 Rewind speed is reduced.

As a result, the slow movement process starts slightly before the end position, and the operating device 330 It is necessary to carefully stop the

on the sides of the running track 47 so that the width of the synthetic belt 3370 extends in the running direction. By arranging the synthetic material belt 337 next to the degree of lateral stability and, on the other hand, stability against rocking movements in the direction of travel. You can also get sex. This also means that the synthetic belt 3 in the operating device 330 37 widely spaced installations are aided by points.

14 and 15 show various filling patterns of rolls of different diameters in the transport container 51. Indicates a turn. A characteristic feature of the storage order of the reel is that the reel is stored in the transport container 51. The principle is to organize items from the center to the outside.

This sequence in particular ensures that the reel that will be located at the edge of the container is predetermined. This position offers two advantages. In FIG. 14, the critical position is number 8. 9.17.18.26 and 27. Here, the gripping machine 332 Despite the small lateral space requirement, the reel can be accidentally placed in the wrong place during storage. You may fall into a position where you are not properly positioned. Therefore, for example, the number 8 reel is number 6. It is possible that the machine may fall to the 0 reel position. However, this position is already occupied. and position 80 ensures that the reel remains in a predetermined location. .

Otherwise, this may cause the central computer to This prevents them from being treated as reserved.

In the container 51 of FIG. 14 and FIG. are placed in front and behind. As is clear from Figure 1, this is true for the four reel frames. It is advantageous if

By locating the operating device 330 on the vehicle 7, the overall self-sufficient vehicle 7 can also be Depending on the concept, the arrangement order will be consistent with the filling patterns in Figures 14 and 15. Implemented to advantage. In the central computer 6, the arrangement order is determined in the transport container 51. It is determined according to the various reel diameters. Already secured in the transport container 51 The location of the reel that follows is stored in the central computer 6. It becomes clear where things have been sorted out. The vehicle is determined by the central computer 6 based on the next sorting point. In the transportation command for 7, the distance from the zero flag 45 to the vehicle's stopping point is determined. Storage according to the filling pattern shown in FIG. 15 is carried out in the transport container 51 shown in FIG. This is shown in the top view. What is well recognized here is that the transport container 51 is It must be fixedly placed during the period. From zero flag 45 to the stopping point Only the length of the travel section changes.

FIG. 16 shows a side view of the operating device 330. In this embodiment, four reel frames 20 are used. A handling device 330 for transport is shown. The grippers 332 are separated from each other by a certain distance. Because they are spaced apart, each of the reels has its windings picked up by the gripper 332. Captured. The operating device 330 has a synthetic belt 33 at the fixing device 346. It is connected to 7. By placing the fixation devices 346 widely apart from each other, Raising and lowering movement of the operating device 330 with less vibration is ensured. The gripper 332 is a reel It is formed so that the surface area is as large as possible at the point where it contacts 20. As a result, only A low surface pressure occurs, which ensures careful handling of the reel 20.

The gripper 332 is rotatably arranged on the rocking element 352.

FIG. 17 shows a side view of the operating device 330. The fixation device 346 is a synthetic bell. The entire width of the plate 337 is configured so that it can be placed on the fixation device 346. compressed air Air cylinder 350 opens and closes gripper 332. Compressed air cylinder 350 It is articulated on rocking element 352 . The rocking element is on the one hand an operating device It is articulated on the fixed part of 330 and on the other hand on the gripper 332. Miscellaneous Further, between the fixed element of the actuating device 330 and the gripping device 332, each is arranged in an articulated manner. A guide frame 351 is provided. This guide frame 351 is used to open the gripper 332. The parallelogram geometry of the center of rotation ensures that the gripper 332 always Make sure it's vertical. This advantageously results in the gripper 332 being slightly lateral when released. This ensures that only the required space is taken up.

This is particularly advantageous when organizing the reel 20 in close proximity to the walls of the transport container 51. . Additionally, this ensures careful handling of the rolls. So This is because only a small frictional force is generated in the windings of the winding frame 20. Grasping machine 332 is rotatably supported on a vertically arranged rotating shaft 353. This grabs Adaptation of machine 332 to a conical reel is possible as follows. In other words, grab Since the gripping device 332 adapts to the shape of the reel, here too the gripping device 332 should be made as large as possible. This is possible by making the large side come into contact with the reel 20.

In FIG. 17, the operating device 330 is shown in a pressure position in which it does not carry a reel. However, Fig. 18 shows the operation when transporting the reel 20 of small diameter and large diameter. A depiction of each half of device 330 is shown. As you can clearly see, it is rotating Parallelogram-like control of the gripper 332 is achieved by the arrangement of the center and the guide frame 351. It will be done. The gripper 332 is therefore independent of the bobbin diameter in the vertical position.

By gripping the reel 20 slightly by the gripper 332, the operating device 330 is already activated. The slight opening ensures reliable loading and unloading of the reel 20.

FIG. 19 shows a vehicle 7 equipped with safety devices 400, 410 and 420. safety gear A station 400 is provided to secure the reel 20 in case of an energy failure.

Due to an energy failure, the operating device 330 can no longer grip the reel 20 securely enough. It is possible that something is wrong. The safety device 400 causes the reel to fall onto the support of the safety device 400. After lowering and energy is supplied to the vehicle again, the reel is moved from this abutment to the operating device. 330. The safety device 400 is rotatably supported by a rotating shaft 401. ing. When the operating device 330 is lowered, it is biased by a spring. The safety device 400 is lowered from the underside of the operating device. The operating device 330 winds up again. , i.e. the safety device 400 moves towards the platform 402 again. Then, the safety device 400 moves the platform 40 again around the rotation axis 401. 2 and rotates below the reel 20. Platform 402 is a safety device 400 is a fixedly connected component of

The safety device 410 functions to prevent a rear-end collision with the preceding vehicle 7. In this example In many cases, ultrasonic sensors are used. Ultrasonic sensors are particularly useful for optical transmission of transport commands. It has been found that the issue of contempt is not raised during the transfer.

As another safety device 420, the vehicle 7 is provided with a rear-end collision prevention device. Collision prevention equipment The contact with the obstacle sends a signal to the drive system of the vehicle 7. In a favorable configuration The motor first switches to slow motion and then stops. This reduces braking distance It has been found to be shorter with an immediate stop of the drive. Obstacle is in front of vehicle 7 is no longer present, i.e. the collision prevention device has returned to its original position. the vehicle will start moving again automatically.

The vehicle 7 is further provided with an indicator 430. Indicator 430 is shown as a solid line It can move from the position to the position shown in dashed lines. Based on the indicator 430, the vehicle 7 The branching device determines in which direction further travel is required to process the transport order. It is obvious for the circuit. If the indicator 430 is in the retracted or protruded position Depending on whether the branching device is moved into a straight position or into a bent position, for example.

In addition, the indicator 430 may be used to determine the function of the storage location, the functionality of the control of the storage location, and/or the It has the function of notifying the central computer of the successful storage of transported cargo.

As soon as the vehicle 7 is in the storage position and the cargo is unloaded, the indicator 430 is in the traveled position. The vehicle is moved and captured by sensors installed along the route. This senna is then Information that the object has been loaded or unloaded is transmitted to the control unit. This information is used in the following transport instructions It can be used to detect the correct storage location of the next cargo.

The invention does not necessarily relate only to the embodiments shown in the figures. i.e. for example Storage of reels is not limited to storage in transport containers of the type described. for example It is also possible to organize the reels into small pallets or type-specific holding sections.
