Definitions

  • the invention relates to a method for transporting a sequence of small-parts containers in a warehouse under a horizontal removal opening of an assembly table, in particular for printed circuit boards.
  • DE 31 14 032 C2 discloses a method for transporting a sequence of small parts containers to a removal opening, in which a bearing located below the working level of the assembly table is moved in such a way that the small parts container contains the small parts required for processing comes to lie below the removal opening.
  • the containers are arranged in a fixed order when they are brought in, so that very short access times are only possible if small parts that are required one after the other are accommodated in adjacent containers.
  • Another known method for transporting small parts containers (brochure from ROYONIC, RHS D 851 A 11/83), which is used in an assembly table with a storage area with small parts containers running around in its rear area.
  • the object of the invention is to create a method for transporting a sequence of small-parts containers to a removal opening, with which very short delivery times for successive containers can be achieved largely independently of the spatial arrangement of the small-parts containers in a warehouse permit.
  • the invention solves this problem based on the method defined above in that at least one of the small parts containers in the warehouse is determined by a program control according to a request, that an access element of a loading and unloading device and the warehouse are moved relative to each other and thereby the access organ is guided to the parking space of the specific small parts container, that this container is removed from the warehouse and moved with the loading and unloading device and a transport arrangement with at least two transport tracks to the removal opening, that after removal of a predetermined number of small parts of the containers via the transport arrangement and the loading and unloading device to an empty parking space in the warehouse selected by the program control and this position is stored.
  • a major advantage of the method is that because of the loading and unloading device and the transport arrangement formed, divided transport path from the warehouse to the removal opening, the transport arrangement can be utilized as a buffer by, for example, during movement in the transport arrangement and des necessary dwelling of a small parts container under the removal opening at least one further, subsequently required small parts container is conveyed by means of the loading and unloading device to the transport arrangement.
  • the design of the transport arrangement can be varied according to the desired working method.
  • the supply and removal of the small parts containers to and from the removal opening can take place from one or more sides as well as on several levels. If it is useful to shorten the transport time, each transport track can be used alternately in one or both directions as required. However, it is to be regarded as particularly advantageous that each small parts container (6) is brought back to the removal opening (8) via a transport track (9a) and to the loading and unloading device (10) via a transport track (9b).
  • a certain number of empty parking spaces in the warehouse makes it easier for the program control to shorten the route taken by the access organ. For example, a small-parts container that is no longer needed is taken to an empty parking space that is as close as possible to the storage space for the next container to be fetched.
  • the arrangement for carrying out the method is characterized in that the mounting table with removal opening is immediately adjacent to the warehouse, that the access element of the loading and unloading device can be guided to any parking space and to the transport arrangement, that the transport arrangement between removal opening and loading and Unloading device is located and that the program control of the loading and unloading device and the transport arrangement is assigned.
  • Such an arrangement offers the advantage of very short transport routes or deployment times.
  • the time that Access organ needed to reach a specific parking space can be further shortened if the bearing is movable - especially linearly be ⁇ movable in the horizontal direction - is. Thus, it can be moved towards the access organ, for example, halfway.
  • the transport arrangement is designed in such a way that it lies outside the area of the printed circuit board to be assembled, the ergonomically favorable arrangement of a horizontal removal opening in the immediate vicinity of the printed circuit board to be assembled can be achieved with a program-controlled cutting and bending tool be combined.
  • a loading and unloading device and at least one transport track are assigned to each sub-storage facility.
  • a connecting device between the stores in order to prevent the occurrence of an overcrowding of an individual part store and not to disturb the work process at the removal opening.
  • This connecting device is preferably equipped with a drivable conveyor device.
  • Each transport arrangement preferably contains a transport device which corresponds to at least one transport track.
  • a horizontally circulating conveyor belt is chosen to connect the supply position and the removal opening, this conveyor belt can both feed and remove small parts containers.
  • a single transport device thus corresponds to two transport tracks, as a result of which the transport arrangement is mechanically simplified.
  • the degree of automation of the arrangement for carrying out the method according to the invention can be further increased if empty small parts containers are detected by means of weighing devices; Using the program control, the empty containers can then be replaced with full ones when using an automatic loading system.
  • FIG. 1 shows a perspective view of a first arrangement for carrying out the method according to the invention
  • FIG. 2 shows the outline of a second arrangement for carrying out the method according to the invention
  • FIG. 3 shows the top view of the second arrangement.
  • FIG. 1 represents a Be Services ⁇ place for printed circuit boards 1. They are fed into stacking containers 2 via a conveyor 3 and a stack lift 4. An operator removes the printed circuit board 1 and places it in the working position of the mounting table 5.
  • the components are located located in small parts containers 6, which are taken below the working level from a warehouse 7 to a Ent ⁇ opening 8 of the placement table 5.
  • the small-parts containers 6 are fed in via an upper transport track 9a and removed via a lower transport track 9b.
  • the small parts container 6 required in each case is determined by a program control which controls a loading and unloading device 10 to its position in the warehouse 7 .
  • the loading and unloading device 10 consists of two linearly movable parts, the horizontal part 10a and the vertical part 10b.
  • the vertical part 10b contains two access organs, the. are assigned to both transport paths 9a, 9b.
  • the upper access organ now removes the container 6 determined by the program control from the store.
  • the loading and unloading device 10 a provision ment position approached at which the small parts container 6 is transferred to the transport path 9a.
  • the lower access element takes over a small parts container 6 from the lower transport track 9b in order to bring it back to the store 7. While the upper transport track 9a brings the small parts container 6 that has just been brought to the removal opening 8, the loading and unloading device 10 fetches the next one and brings the one that is no longer required to an empty storage space in the warehouse 7.
  • the position of the parked container 6, which is new in most cases, is saved.
  • the delivery time specified by the operation of the loading and unloading device 10 is on average shorter than the time required by the operator of the loading table 5 for the loading of a printed circuit board 1 with the components from a container 6. This makes it possible to use several Line up small parts container 6 on the transport path 9a. Thus the loading time of the operator is not lengthened by the preparation time for the small parts container 6 .
  • a monitor 11 informs the operator of the number of small parts to be removed. To do this, it takes about three seconds on average and can then use the foot switch 12 to replace the small parts container 6 . This results in an average availability time for the loading and unloading device 10 of less than three seconds.
  • a luminous pointer 13 which is also guided by the program control, indicates to the operator the position of the small parts on the printed circuit board 1 to be fitted. Below the printed circuit board 1 there is a cutting and bending tool (not shown). This shortens the connecting wires of the small parts and bends them so that they do not come out of the solder bath during the onward transport of the printed circuit board 1 PCB 1 can fall. Since the printed circuit boards 1 have different sizes, 14 mask inserts are stored on a shelf for adaptation.
  • Empty small parts containers 6 can be detected by a weighing device, for example in the vertical part 10b.
  • the program control then regulates the exchange of empty containers 6 for full ones with the aid of an external loading system. This exchange takes place via the side of the bearing 7 facing away from the mounting table 5.
  • simpler solutions to this problem are also conceivable. If, for example, the original number of small parts in a container 6 is stored in the program control, then by subtracting the number of small parts removed, the program control can determine the time for filling the corresponding container 6 .
  • Two assembly tables can also be arranged on the same side of a shared warehouse. With correspondingly rapid movements of the loading and unloading device 10, it can be used to supply both placement tables—preferably arranged opposite one another.
  • the second exemplary embodiment shown in FIGS. 2 and 3 differs from the first essentially by a two-part store 7a, 7b and a transport arrangement which further shortens the availability times of the individual small parts containers 6 due to flexible operation.
  • Each of the two sub-warehouses 7a, 7b has its own loading and unloading device 10--shown only for sub-warehouse 7a--assigned to one access organ each.
  • the transport arrangement consists of two transport paths 9, which lead to the removal opening 8 from two opposite sides. The special feature of this arrangement is that now each of the two transport paths 9 small parts container 6 can supply or discharge, either independently or in combination.
  • the program control determines the direction of transport depending on whether small parts containers 6 have to be fetched from the right part store 7b or the left part store 7a. If a small parts container 6 is brought under the removal opening 8 from the left, for example, it is advantageous to transport it away to the right if the next one also comes from the left. However, if the next one is already on the right, the small parts container 6 must be moved to an empty parking space on the left. In order to be able to maintain this working method with only a slight oversupply of empty parking spaces, an additional connecting device 15 is required. This ensures compensation by enabling small parts containers 6 to be moved from one sub-storage facility 7a or 7b directly to the other transport animals.
  • the small-parts containers 6 can be returned to any empty parking space, and their position is also stored by the program control.
  • the removal opening 8 is twice as long and is provided with a sliding cover. From two sides, the small-parts containers 6 are supplied from two part stores 7a, 7b via two transport tracks 9a, 9b each, as well as removed. The part of the removal opening 8 required in each case is released by the sliding cover.
  • the transport arrangement and the connector 15, devices can be used in the exemplary embodiments, as shown in the prospectus "Modular Handling System” from Siemens, MCH 01810.8310.
  • the loading and unloading devices 10 can consist, for example, of so-called “gantry loaders”, such as she shows on page 3.
  • the transport tracks 9, 9a, 9b of the transport arrangement and the connecting device 15 can be "portal axes" according to page 6. It is also by no means mandatory to arrange the bearing 7, 7a, 7b in a linear manner.
  • a rotatable and pivotable arm as the loading and unloading device 10 it is also possible to set it up along part of an arc of a circle.
