Description

The The invention relates to a system and a method for supply a machine with reworkable tools.

manufacturing machines need Tools that perform certain operations carry out have to. These tools wear off in the course of use, so that they must be discarded. In many cases However, the tool can be reworked, for example, reground. To minimize downtime keeping it small has to be taken care of be that constantly Tools are available that are against the useless tools can be exchanged.

In a known feeding device for machine tools ( DE 40 36 380 A1 ) are picked up by a handling device tools or pallets from a pallet rack and fed to the machine tool.

Also known is a method for supplying a machine tool with tools ( DE 40 32 003 A1 ), in which a tool changing device, when it is not needed for transporting a tool to the machine tool, can transport tools from a tool lock to a storage location in the tool magazine.

Also known is a storage device for a machine tool ( EP 24 07 09 A1 ), in which tool units can be transferred from and returned by a handling device of the machine tool.

Of the Invention is based on the object, a system and a method to provide one or more machines with tools can, where both the use of brand new as well as reworked Tools may be possible should.

to solution this task strikes the invention an attachment with the in claim 1 and a method with the features mentioned in claim 17.

further developments The invention are the subject of subclaims.

If on the machine a tool is no longer usable, it can taken out and into the magazine for the unusable tools are inserted or introduced. In The machine can then either use a tool from the magazine for brand new Tools or one from the magazine for reworked tools be used. The tool is removed from the magazine for the brand new tools taken, so there can be a registration, where both the fact of removal as well as the type of tool removed is registered, provided the magazine several types of tools contains. Under type of tool is also a different size with otherwise the same Tool to understand. By registering the removal can ensured be that, for example in an overview can be displayed, how many tools and what type still contained in the magazine.

According to the invention can fill the magazine for the brand new tools be provided with an input device with their help the number and type of hand in the magazine introduced tools can be noted. If, for example brand new tools delivered together with a delivery note can be noted on the type and number of tools, the Input device be designed so that they read the delivery note can. Instead of a delivery note, of course, a machine-readable only disk be used. In this way you always have an accurate one Information about the number and type of tools contained in the magazine.

Especially can be provided that the Magazine for the brand new tools with a computer, such as a PC, in whose memory the contents of the magazine and the Additions and disposals of the magazine are noted. Of course, other data can still be noted, for example, the time of removal and / or the input of new tools, so that a consumption statistics can be led.

Especially can also be provided in development of the invention that the removal device and / or the input device are connected to the computer.

In a further development of the invention can be provided that the magazine is designed for the brand new tools as a closed container with an output shaft. Output tray is a device through which the tool is dispensed, no matter which tray within the magazine it originates from. When dispensed through such a shaft, the fact of the removal can be checked and registered with little effort. The selection of the tool to be issued may be similar Lich as in a vending machine by selecting a keypad done, for example, a keypad on which the tools to be removed are displayed directly.

In Further development of the invention can be provided that with the Notation of removal of a brand new tool from the magazine a debit is connected to an account of the operator of the facility is. This means that the Tool in magazine still owned by the manufacturer of the tool is and that one Buying process so that is done exactly at the time to which the tool indeed is used. Through this arrangement of the magazine for the brand new, tools still owned by the manufacturer next to one Magazine for reworked tools that are already in the user's property can be achieved, an economic storage can be achieved.

In Development of the invention, the system can be a time and / or event-controlled Data communications equipment to transfer the inventory data and / or the transaction data to the manufacturer of the tools included. In this way, both reorders can be ordered as well as the charges on the account at regular intervals to date bring.

In repeated development of the invention can be provided that the tools a particularly machine-readable, the type of tool indicating Have marker. This can be, for example, a Code on the shaft, a ring in a color or the like. Act, wherein the width and / or the color of the ring the diameter of the tool can denote.

The Input device can, for example, a device for reading an accompanying document, such as a delivery note. This device may be a scanner for the delivery note act, either a handheld scanner or a scanner, in the delivery note is inserted. This can be relative quickly read the data into the computer, taking the delivery note then also by the persons themselves can be read.

The Output means may be means for checking the tool to be dispensed contain and possibly a return option, if a wrong tool was selected has been. This may be the possibility considered be that when refill the magazine a brand new tool in a wrong manhole was inserted. If the selection of the tool to be output via a Keypad leads to a particular subject and in the tray an incorrect Tool is included, so in the output device, for example in the output slot, nevertheless, a correction done before the Tool actually spent and get paid for it. This verification option may be a visual check, For example, a window where the user can view the tool can. Also possible is also an automatic check, namely, then when the tools have marks. These can be on be read this place. Is it a wrong tool, so this can be done by pressing a key or automatically put into a return box, from where it gets back into the magazine without a burden or calculation takes place.

Becomes Nevertheless, taken a wrong tool, this is in a separate Storage box (mailbox) deposited and by the operator of the machine at next Opportunity reversed.

While that Magazine for the brand new tools with advantage designed as a closed box is, can the magazines for the reworked tools and the unusable tools be designed as open shelves. These tools are located yes already in the ownership of the operator of the plant. Under the expression Closed box or closed container can also be one Device to be understood, which is closed by grids, because it matters here that the Removal only through an output shaft in the sense mentioned possible is.

to easier identification and easier operation of the system can be provided according to the invention be that the Magazine for the reworked tools and the unusable tools are marked differently in color. For example, can one the shelf for training the finished tools in red, as a warning color, while the reworked tools are stored in a green shelf.

The Plant can according to the invention a station have summarized in which the nachzubearbeitenden tools and the Postprocessing will be sent. This station can be independent of the movement processes work between individual magazines, provided the capacity of each Magazine is correspondingly large. It can so at regular intervals the shelf for the no longer useful tools these removed and packages be summarized. The rest, too operations namely the filling the shelves for the reworked tools and possibly the brand new tools can be independent of each other done without a downtime for the Machine is created.

The Shipment station may also have a device for checking the tools then Include whether post-processing is still possible. If a tool after frequent Regrinding has become too short, it can not be sharpened further become. He must then be sorted out, so that one dispose of it.

Especially can be provided that the Shipment a means of creating a the quantity and comprising the types of data carrier to be reworked characterizing. Again, this may be again a delivery note, the can be read by both persons and machines. If the tools to be reworked in a package with the delivery note be taken away, so it is possible, for example, at the specified Redelivery date these tools use the same delivery note. Then exists the control only in the comparison of the delivery note.

At the For the rest, sorting out the tools for their disposal can also be done the mark, if it is a component of another Material is traded, removed and disposed of separately.

Further Details and benefits The invention will become apparent from the following description of a preferred embodiment of the invention, the claims, the text of which is incorporated by reference into the content of the description as well as the drawing. Hereby show:

1 schematically an overview of the system according to the invention with the most important parts;

2 in more detail the arrangement of the magazine for the brand new tools;

3 a diagram representing the treatment of the tools to be reworked.

1 shows in a highly schematic overview of the most important parts of the proposed system of the invention, with a machine 1 can be supplied with tools. For the sake of simplicity, it is assumed below that the tools are drills that are in the machine 1 used for drilling holes. This system contains a first magazine 2 , which is designed as a closed container. In the magazine 2 The brand new drills are contained in compartments. These drills differ, for example, in their diameter and in their length, possibly also in other features, since it also requires drills with different cuts for different materials. The magazine 2 for the brand new drill is via a data line 3 with a computer 4 connected, for example, designed as a hard drive memory 5 having. Everyone in the magazine 2 included drill is in the store 5 of the computer 4 noted. The removal of drills from the magazine 2 can only be done automatically by a user at a selector 6 Press a specific key associated with a particular type of drill bit. The drill is then removed from the magazine 2 taken and spent. The movement of the drills is in the scheme of 1 represented by individual arrow lines. The removed drill can therefore to the machine 1 brought and used there. At each removal of a drill, for example, triggered by pressing the keypad of the selector 6 , an entry is made in the memory 5 of the computer 4 according to which a particular tool was removed at that exact time. This removal, and the note produced by it, results in an account of the operator of the installation being debited with the value of the drill. The drill goes so with its removal from the magazine 2 into the property of the operator of the facility, while previously owned by the supplier of the drill.

To replace a drill in the machine 1 can not just a functioning drill from the magazine 2 but also off the shelf 7 be removed. The shelve 7 contains reworked drills, ie drills that have been reground, for example. The drills on the shelf 7 So have been used before or in other words, they are already in the ownership of the operator of the system. Therefore, if necessary, first a drill from the shelf 7 taken as long as the desired type on the shelf 7 is available. Only if on the shelf 7 If no drill of the desired type is left, a removal from the magazine took place 2 for the brand new drills.

The dulled drills coming out of the machine 1 be removed, are in the shelf 8th inserted, in which all blunted drills are included. Off the shelf 8th The drills can then also be removed and sent for reworking, ie regrinding. The reworked drills can then be returned to the shelf 7 be introduced. All processes, namely the filling of the magazine 2 with brand new drilling, filling the shelf 7 with reworked drills, removing the drills from the magazine, inserting the dull drills into the shelf 8th , etc., can be done independently, as the shelves 7 . 8th and the magazine 2 have sufficient capacity. There are therefore no downtimes.

2 shows in more detail the operations during the removal and filling of the magazine 2 for the brand new drills. The drills, for example, in a container 9 delivered. The container 9 is opened and the drills are checked and distributed. It is from the container 9 a delivery note 11 taken. This is represented in the scheme by the double arrows. The double arrows should represent an information transfer. The checked drills are then manually inserted into the open magazine 2 inserted. At the same time or immediately afterwards the delivery note becomes 11 containing information about all the drills by means of an input device 12 read and in the computer 4 entered. At the input device 12 For example, it could be a scanner 13 act, which is symbolically indicated. After filling the magazine 2 with brand new drilling and reading the delivery note 11 is in the store 5 of the computer will contain a complete listing of all drills.

When removing a drill from the magazine 2 takes place at 14 checking if the drill that has entered the exit chute is actually the drill that is on the keypad of the selection device 6 was selected. This check can be carried out either optically by the user of the system or automatically with a corresponding marking of the drill. Join the review 14 Out that the drill is the right drill, it is ejected from the output shaft. At the same time takes place in the memory 5 of the computer 4 a note that a drill of a certain type has been taken.

If it turns out during the check that this is not the correct drill, it will be put into a rebook box 15 from which he returns to the magazine 2 can get. At the same time a stock correction, which then also via an input device 16 in the computer 4 is entered. Again, this may be a scanner 13 Act a phrase of wrapping box 15 read.

With the computer 4 is a data transmission device 17 For example, a modem that communicates data to the drill supplier at regular or irregular intervals. The transmitted data may be order data, billing operations or the like.

Based on this transmitted data, a calculation of the delivery of the drills and also a reordering takes place. The transmission of the data can for example be done daily at a certain time. Of course, a transmission is also possible when a particular event occurs, so for example, the degree of filling of the magazine 2 falls below a certain value.

3 shows schematically the process, as the dull drills from the shelf 8th be treated further. The shelf 8th is a separate station 18 assigned to the drill from the shelf 8th taken and checked. If it turns out during the check that a certain drill can no longer be reground, the mark consisting of a ring is removed and the drill is separated from the ring for disposal 19 given. The drills that can still be reworked will be added 20 summarized and in a container or package 21 brought. At the same time is at 20 a delivery note 22 created, so a list of drills included in the package 21 are included. The delivery note 22 contains a table containing the number of drills for each drill type. The package 21 is then taken to the regrinding service, for example the supplier of the drill. After regrinding the drills are the same drills that are in the package 21 were in a new package 23 brought back to the facility at a given time. Again, after opening the package 23 the drills at 24 checked and in the shelf 7 distributed. In the package 23 is the delivery note 22 included in the 20 was created. This returned delivery note 22 will be checked. The package 23 Contains the same drills as the package 21 , but now in reworked condition.

It is possible that in the computer 4 For each drill type a minimum inventory and a reporting inventory is defined. The subjects of the magazine 2 are divided according to the consumption of drill types. This division may be due to the computer 4 stored data can also be changed if the need changes.

Instead of using a scanner 13 It is also possible to use a bar code reader, or else a machine-readable data carrier, for example a floppy disk. Of course, manual inputs can also be used via a keyboard.

The filling of the magazine 2 for example, once a week. However, if there is a greater need, it may be due to the transfer of consumption data and a more frequent refill.

The processing of blunt drills on the shelf 8th can be sorted by type, for example by assigning a specific type to each day of the week.
