[Conventional technology]

Known from European Patent No. 0060444,
The device for plating components has at least one pretreatment bath, a plating unit, and an aftertreatment bath. Each of these processing stations has a plurality of processing cells, each of which is supplied with a respective process medium. In order to transport the components, a moving device is provided, so that in addition to the actual processing time at the processing station, corresponding loading and unloading times have to be taken into account. The loading, unloading and transport times are therefore added to the processing time of the longest process to form the total cycle time, ie the time during which the component is transferred further.

[Problem to be solved by the invention]

The object of the invention is to improve a device for surface treatment of component hangers of the type mentioned in the introduction, which makes it possible to shorten the cycle time for a given treatment time with as little expense as possible. The object of the present invention is to provide an apparatus in which the number of components coated per unit time can be significantly increased.

[Means to solve all problems]

In order to solve this problem, an inventive configuration is provided in which each processing station is assigned at least one second processing plane, which processing plane has the same number of processing cells as the first processing plane. , components were supplied alternately to these processing planes.

〔Effect of the invention〕

According to the invention, by arranging the processing planes in this way and supplying these processing planes with components alternately, it is possible to significantly shorten the cycle time. If, for example, the transport time approximately corresponds to the longest processing time, the arrangement of two processing planes allows approximately a multiple of the components to be covered per unit time.

In such a case, a doubling of the equipment efficiency is obtained, while the costs for installing the second processing plane are small compared to the total equipment costs, so that a significantly lower investment per workpiece is obtained.

At the same time, a space-saving installation is obtained. This is because only the processing station can be changed by arranging another processing plane.

In one inventive configuration, the processing planes are arranged horizontally and on top of each other, so that the entire installation is not subject to expansion or extension, but is constructed higher only in the area of the processing stations. .

A particularly advantageous embodiment of the device is obtained in that the treatment planes are arranged in such a way that they run vertically and parallel to each other. Such a vertical arrangement makes it possible to dispense with the handling/unloading times required in a horizontal arrangement when loading and unloading components from the processing cell, which reduces cycle times. Bring forth. Furthermore, cleaning is also improved when the components are vertically arranged in the cleaning station. The reason is that better chiseling is guaranteed.

According to the invention, the process medium is supplied alternately to the processing plane, so that a uniform and continuous use of said process medium is guaranteed. In this case, up to 100% of industrial equipment that is not normally used for optical separation during the process, such as transport units, media systems, energy, control equipment, disposal equipment, etc., is used for optical separation. . Furthermore, according to the invention, at least five processing cells are arranged in one processing plane. By increasing the number of cells in each processing plane, higher equipment efficiencies can be obtained as well.

A particularly economical method of operation with a simple construction of the device according to the invention is obtained in that the processing plane of each processing station is followed by a cleaning station with a cleaning plane offset. A very powerful use of the cleaning station is therefore obtained in this case.

〔Example〕

In the following, embodiments of the invention will be explained in detail with reference to the drawings.

The illustrated device according to the invention has a complete transport unit 1, which is arranged to be movable horizontally and vertically and consists of gripping units connected to one another.

These gripping units are equipped with grippers 2.

The transport unit 1 supplies components to the stations of the apparatus which are arranged one after the other and located below the transport unit. The first station, supply station 3, is equipped with components (not shown in FIG. 1) corresponding to the number and position of the grippers 2 arranged in each gripping unit. A processing station 4 is provided in addition to the supply station 3.
This processing station has a first processing plane 11 and a second processing plane 12 . In the exemplary embodiment shown, five processing cells 13 are assigned to the processing plane 11 and ninety-five processing cells 14 are assigned to the processing plane 12. Typically, the components are cleaned at this first processing station 4. In the next transport step of the transport unit 1, these components are brought to a cleaning station 7, which is equipped with only one cleaning plane 15. The structure of the subsequent processing stations 5 and 6 corresponds to the processing station 4, and the cleaning stations 8 and 9 take over the cleaning process sound after the treatment in the treatment station 5 or 6. The processing station 5 serves, for example, for etching the component 16, while the processing station 6 carries out surface refining, for example by chroming. , is removed from this device at this location.

When processing component parts in this device, it is possible to start from the fact that all stations 3 to 10 have introduced component parts 16 and that transport unit 1 is located in the position shown.

These components are then, for example, processed at processing station 4.
．． Processing cells 1 provided in the first processing plane of 5 and 6
It is drawn from 3. Subsequently, the transport unit 1 sends out a gripping unit with two grippers to grasp the components 16 located at the stations 3 to 9, and then the components 16 are removed from the unloading and drying station 10. In order to further transport said components by one processing step, they are raised together with these components into the transport unit 1 and subsequently moved to the right to the next station. This transport unit thus moves, for example, from processing station 4 to cleaning station 7 or from processing station 5 to cleaning station 8. After the transport unit 1 has been lowered, electrical energy contact is made, if necessary, in particular at the processing station 6. In the next step, the gripper 2 releases the component and the transport unit 1 moves upwards and to the left back to the starting position. At the same time, component 16 is drawn into processing cell 13. The next working cycle is defined in relation to the processing time that takes the longest, for example in the processing station 6, and this working cycle is defined in the processing cell 14.
The process begins with these components being pulled out after the processing time has elapsed. The aforementioned working sequence then now takes place in the second processing plane 12 of the processing stations 4, 5 and 6.
repeated for. Since the image processing planes 11 and 12 are operated alternately and the transport time is only slightly shorter than the longest processing time, the transport unit 1
This results in extremely short downtimes. The reason is that this transport unit allows processing stations 4.5 and 6.
This is because the image processing planes 11 and 12 of are operated alternately.

Such a device is easily possible in which the components are arranged vertically for processing and also have a plurality of mutually parallel processing planes. The only difference is in the structure of the gripping device and the processing cell, the working sequence being carried out in this case as well as in the previously described embodiment. If the processing cells are arranged vertically, it is not necessary for the components to be taken out of these processing cells and loaded parallel to them during replacement, and the workpiece is not a functional subsurface. Advantageously, part accuracy is improved because of the grip.

Cycle time is correspondingly reduced by the time required for parallel unloading and loading.
