Definitions
- the invention relates to a brush manufacturing machine with a drilling and / or tamping device and optionally downstream, further processing devices, for. B. for shearing, for rounding, for cleaning the bristles, a processing device is followed by a test device for final inspection of the brushes at least for completeness of the bristle fields.
- the invention also relates to a method for checking brushes.
- a brush production machine has already been proposed in which the processing devices have one Measuring and or testing device is connected downstream, by means of which the brushes can be checked at least for completeness of the bristle field (cf. DE-OS 34 17 086).
- This test device can have one or more mechanical scanners, by means of which it can be checked in the individual perforated field positions of the brush by lowering these scanning elements on the bristle field whether all tufts of bristles are present, as a rule also using movable optical test devices (cameras).
- test devices can be quite advantageous and are designed in particular as additional devices for existing brush manufacturing machines.
- installation of movable cameras is quite expensive in these known control devices.
- the solution according to the invention essentially consists in the fact that in a brush production machine of the type mentioned at the outset, the test device has one or more fixed recording cameras or the like and that a transport device for feeding and / or positioning brushes in a test zone of the recording camera (s) is provided .
- the solution according to the invention consists, in particular, in that the brush moves through at least one test zone and scans its bristle field, possibly its imprint or the like, for faulty deviations from at least one predefined pattern and when a deviation from the pattern occurs at least one signal is given.
- Both the test device belonging to the brush production machine mentioned at the outset with at least one fixed camera and the corresponding checking method working with at least one fixed camera also have the advantage that the test times are very short and, accordingly, the throughput of brushes to be tested is large. Therefore, such a testing device or an associated method can also be used well for testing the products of several individual brush manufacturing machines.
- Fig. 1 u. 2 essentially shows a transport device with a circulating conveyor belt 2, on which workpiece holders 3 for brush bodies 4 or for finished brushes 5 are located.
- processing devices of the brush manufacturing machine 2 are shown schematically, in particular post-processing devices.
- Fig. 1 you can see a shearing station 6 and two post-processing stations 7 u. 7a for rounding off the bristle ends.
- two control or inspection devices 8 are then arranged, by means of which a final inspection of the finished brushes 5 is carried out.
- test device 8 Although the arrangement of a test device 8 according to the invention or the corresponding test method is not tied to the arrangement of a specific processing or postprocessing station, it is particularly expedient there if the test device (s) 8 is connected downstream of the last processing station, here that 7a for rounding off the bristle ends is so that you get a final inspection of the finished brush 5.
- test device (s) 8 is connected downstream of the last processing station, here that 7a for rounding off the bristle ends is so that you get a final inspection of the finished brush 5.
- each brush can be checked for completeness of the bristle field image with regard to the bristle tuft lengths and the like in a quick manner.
- test devices 8 can have mechanical scanners arranged above and / or laterally from this bristle field to check for completeness of the bristle field and are connected to corresponding contacts.
- Fig. 5 shows a brush manufacturing machine 1 of the type mentioned, in which the test device 8, a fixed recording camera 38 or the like.
- Has testing device wherein a transport device 39 is provided for feeding and possibly positioning the brushes 5 in a test zone 40 (cf. FIG. 8) of the recording camera 38. 5 and 8, the respective recording camera is positioned on the face side adjacent to the bristle field 17 of the corresponding brushes 5.
- a test device 8 in which a deflectable sensing tab 34, which is arranged above the bristle field 17, is provided as a mechanical scanner. This is pendulum-like and rests against a stop 35 in the rest position (FIG. 3).
- the lower end face of the touch tab 34 is positioned directly above the top of the bristle field 17.
- This end face 36 can also be adapted in its longitudinal profile to the corresponding profile of the bristle field.
- the feeler tab 34 covers the correspondingly flat bristle field 17 of a brush 5 in the longitudinal direction with a linear end face 36.
- a position sensor 37 for example a reflective light barrier, is arranged adjacent to the touch flag 34, by means of which a deflection position of the touch flag 34, as shown in FIG. 4, can be signaled.
- the brushes 5 move according to the arrow Pf 1 on a transport path, not shown here with appropriate brush holders below the button flag 34. If one or more bristles protrude beyond the intended height of the bristle field 17 in the incorrect position 19, the touch flag 14 is taken along accordingly by the transport movement of the brush 5. As a result, the position sensor 37 can recognize this brush 5 as faulty.
- the position sensor thus works in connection with the touch flag similarly as the recording camera 38 already described in connection with FIGS. 5 and 8. After the brush 5 tested has passed, the touch flag 34 swings back against the stop 35 into its initial position (FIG. 3 ) back.
- FIG. 7 shows a test device 8 with a plurality of recording cameras 38a, 38b u. 38c.
- the brushes 5 to be checked are transported past these recording cameras 38 by means of the transport device 39 already mentioned.
- the respective test object In the area of the test zone 40 (FIG. 8), the respective test object can be positioned in a stationary position for a short time during the test process.
- the test times of the recording camera (s) 38 are very short.
- 8 shows only one recording camera 8; with this arrangement, of course, the further recording cameras 8b u. 8c may be provided.
- Fig. 7 it can be seen particularly well on the test device 8 that two recording cameras 38a and. 38b are arranged at an angle to one another. You can check the bristle field 17 in the direction of the end face and the direction of supervision at the same time.
- the recording camera 38b arranged above the bristle field 17 serves in particular for recognizing errors due to missing or incomplete tufts of bristles, while the front-mounted recording camera 38a can capture the errors shown and described in connection with FIG. 6 well.
- the testing device 8 also includes a third recording camera 38c for checking a stamp imprint 41.
- z. B one of the fixed recording cameras 38 or the like. be designed to be laterally movable, for example for checking the bristle field 17 and the stamp imprint 41 (FIG. 7).
- the recording camera 38 which is fixed relative to the test specimen, can be arranged to run in regions in the transport direction during the test process when the brushes 5 to be checked are continuously passed through.
- a step-by-step transport movement with the test specimen at a brief standstill during the test phase can also be expedient.
- one of the recording cameras 38 is used for a number of test points - e.g. Bristle field view and stamp imprint (cf. FIG. 7) - this camera 38b can take part in a transport step for the second inspection process with simultaneous repositioning in order to achieve a uniform sequence of steps with practically no dead time.
- the checking of the brushes 5 with recording cameras 38 takes place by means of a comparison measurement with a reference pattern of a good brush stored in the respective camera. It is possible to deviate several reference patterns in one camera, so that they can also check different brushes or on different test centers can be used. The reference patterns are then switched accordingly. As a result, there is also the possibility that a test device 8 separate from the rest of the brush manufacturing machine can be used for several brush machines. With this alternate or optional checking of different brushes, the switchover to the different reference patterns can take place either quickly and preferably automatically in accordance with the production sequence; or you can switch from an identifier on the brushes or the feed devices or the like. Taxes.
- Another option for checking different brushes 5 within a production sequence is that all the different brushes 5 provided are stored in the camera as reference patterns. If a test object is then in the test area of this recording camera, all stored reference patterns can be activated one after the other and compared with the test object. If the conformity with one of these reference samples is determined, this test object is considered "good”. Otherwise, the brush is removed from the further transport route.
- Test devices can also be connected to an evaluation unit which e.g. gives a signal when errors accumulate. Such an accumulation of errors can e.g. are present if a predeterminable number of defective brushes occur in succession or if a certain, predeterminable number of defective brushes occur in a certain period of time.
- the devices according to the invention can be used in particular for toothbrushes, but also for other quality brushes.
- a plurality of recording cameras 38 can also be expediently provided if there is no complete control option in one viewing direction, e.g. because of himself mutually covering bristle tufts 9.
