Abstract

In the manufacture of segment filters, appropriately prepared segments (1) are transferred through a delivery zone (2) to a separation zone (4) equipped with a separating unit (5), and then transferred between the drivers (8) of a rotating disk (9) mounted on axis (10), which constitutes a transferring unit (11), and intercepted by the said unit (11.) in an interception zone (T), they are transferred individually through a transfer zone (12) to a placement zone (14), where they are positioned on the horizontal track of the grouping belt (13), and in the case of incorrect flow of filter segments (1) in any zone (2, 4, 7, 12, 14) and/or between the zones, the process of the transfer of the filter segments in at least one zone is interrupted, which causes the interruption of the filters production process. Detection of incorrect flow is effected by means of checking the resistance to motion of mechanisms by means of checking the driving torque of a motor in each zone, or by checking the change of the position of the mechanisms by means of a sensor (1_7) fixed in the transferring unit ({umlaut over (υ)}) and/or the separating unit (5). The interruption of the process is effected by removal of the transferring unit (H) and/or the separating unit out of the filter segments' (1) flow track, and the removal may be effected by means of a pneumatic cylinder moving the transferring unit (H) along its guide (16) of the axis parallel to the axis of rotation (10) of the unit (H.) or the rotating the unit around the axis of the guide. Mounted together on one guide, the separating unit and the transferring unit may be removed together by moving along a guide perpendicular to the axis of rotation of the transferring unit or by rotating around the axis of a guide parallel to the axis of rotation of the transferring unit.

Example Embodiment

[0005] Example I. figure 1 In the case shown, the section 1 suitably made is conveyed as a finished product string through the zone 2 to the zone 4 including the conveyor 3, where the section is separated by a separation assembly 5, which is a fixed ramp 6, and transfer between the drives 8 of the rotating disk 9 installed perpendicular to the horizontal axis 10 in the zone 7, which constitute the transfer assembly 11. The separation section 1 intercepted by the driver 8 in the zone 7 is separately transferred to the zone 12 and placed on the horizontal track of the group belt 13 in the zone 14, and the required section 1 is produced by transferring it to the next module in this way. . The shaft 10 of the disc 9 is installed in a horizontal extension arm 15, the arm is slidably installed on a guide 16 parallel to the shaft 10, and the extension arm 15 is combined with a sensor 17 installed near the shaft 10. The sensor 17 detects that the position of the disc 9 together with the shaft 10 has changed, or the resistance of the machine movement has increased, and the control system will activate the pneumatic cylinder, which is not shown in the figure. figure 2 The extension arm 15 and the conveying assembly 11 are moved in the direction indicated by the arrow 18 to stop the conveying process of the section 1, thereby stopping the filter production process.
[0006] Example II. image 3 In the case shown, the section 21 suitably made is transported as a finished product string through the zone 22 to the zone 24 including the conveyor 23, where the section is separated by a separation assembly 25, which is a fixed ramp 26, and transfer between the drives 28 of the rotating disk 29 installed horizontally to the vertical axis 30 in the zone 27, which constitute the transfer assembly 31. The separated section 21 intercepted by the driver 28 in the zone 27 is separately transferred to the zone 32 and placed on the horizontal track of the group belt 33 in the zone 34, and the required section 21 is produced by transferring it to the next module in this way. . The shaft 30 of the disc 29 is installed in a horizontal extension arm 35, the arm is rotatably installed on a guide 36 parallel to the shaft 30, and the extension arm 35 is combined with a sensor 37 installed near the shaft 30. The sensor 37 detects that the position of the disc 29 together with the shaft 30 has changed, or the resistance of the machine movement has increased, and the control system will activate the pneumatic cylinder, which is not shown in the figure. Figure 4 Rotate the extension arm 35 and the conveying assembly 31 in the direction indicated by the middle arrow 38 to stop the conveying process of the section 21, thereby stopping the filter production process.
[0007] Example III. Figure 5 In the case shown, a suitably manufactured section 41 is transported as a finished product string through the zone 42 including the conveyor 43 to the zone 44, where the section is separated by a separation assembly 45, which is a ramp 46, and The area 47 is transferred between the drives 48 of the rotating disk 49 installed perpendicular to the horizontal axis 50, which constitute the transfer assembly 51. The separation section 41 intercepted by the driver 48 in the zone 47 is separately transferred to the zone 52 and placed on the horizontal track of the group belt 53 in the zone 54, and the required section 41 is produced by transferring it to the next module in this way. . The extension arm 55 is mounted on the shaft 50 of the disc 49, and the end is a ramp 46. The extension arm 55 is slidably mounted on a guide 56 perpendicular to the shaft 50 and combined with a sensor 57 installed near the guide 56. This installation method enables the separation assembly 45 and the conveying assembly 51 to be combined stably. The sensor 57 detects that, for example, the position change of the disc 49 or the ramp 46 caused by the drive 48 colliding with the previously incorrectly positioned segment 41 on the belt 53 or the increase in the resistance of the machine movement, the control system Will activate the pneumatic cylinder, not shown in the figure, Image 6 Move the extension arm 55 and the ramp 46 that compose the separating assembly 45 and the conveying assembly 51 in the direction indicated by the arrow 58 to stop the conveying process of the section 41, thereby stopping the filter production process.
[0008] Example IV. Figure 7 In the case shown, the section 61 suitably made is transported as a finished product string through the area 62 to the area 64 including the conveyor 63, where the section is separated by a separation assembly 65, which is a rotating disc cam 66, and In the zone 67, it is transferred between the drives 68 of the rotating disk 69 installed perpendicular to the horizontal axis 70, which constitute the transfer assembly 71. The separation section 61 intercepted by the driver 68 in the zone 67 is separately transferred to the zone 72 and placed on the horizontal track of the group belt 73 in the zone 74, and the required section 61 is produced by transferring it to the next module in this way. . The shaft 70 of the disc 69 is mounted on a vertical extension arm 55, the vertical extension arm 75 is slidably mounted on a guide 76 parallel to the shaft 70, and the rotating disc cam 66 is mounted slidably parallel to the shaft. In the joystick 79 in the guide 76' of the 70, its rotation axis is perpendicular to the axis 70 of the disc 69. The separation assembly 65 and the transmission assembly 70 are not connected to each other, but affect the sensor located between the assemblies 65 and 71 77. The sensor 77 detects that the position of the disc 69 and/or the cam 66 is changed, or the resistance of the machine movement is increased, which is caused by the driver 68 colliding with the previously incorrectly positioned segment 51 on the belt 73, and the control The system will start the pneumatic cylinder, not shown in the figure, one of the pneumatic cylinders Figure 8 Slide the extension arm 75 in the opposite direction as indicated by the arrow 78, and the other pneumatic cylinder Figure 8 The cam 79 is slid in the opposite direction as indicated by the middle arrow 78 to stop the conveying process of the section 61, thereby stopping the filter production process.
[0009] Example V. Picture 9 In the case shown, the section 81 suitably made is transported as a finished product string through the zone 82 to the zone 84 including the conveyor 83, where the section is separated by a separation assembly 85, which is a rotating disc cam 86, and In the area 87, it is transported between the drive 88 of the rotating disk 89 installed perpendicular to the horizontal axis 90, which constitutes the transport assembly 91. The separated segment 81 intercepted by the driver 88 in the area 87 is separately transferred to the area 92 and placed on the horizontal track of the group belt 93 in the area 94, and the required segment 81 is produced by transferring it to the next module. . The shaft 90 of the disk 89 is mounted on an extension arm 95, the rotating disk cam 86 is mounted on the end of the extension arm, the rotation axis is perpendicular to the shaft 90 of the disk 89, and the other end of the extension arm 95 is rotatably mounted in parallel On the guide 96 of the shaft 90. The extension arm 95 is combined with a sensor 97 installed near the shaft 90 of the disc 89. Since the separation assembly 85 and the transmission assembly 91 are fixedly combined with the extension arm 95, the sensor 97 can detect the disc cam 86 and/or the disc. Any change in the position of 89. For example, the position change signal of the disc 69 and/or the cam 66 caused by the driver 88 colliding with the previously incorrectly positioned segment 81 on the belt 73, or the increase of the resistance of the machine movement will be transmitted to the control system. The control system will activate the pneumatic cylinder, which is not shown in the figure. Picture 10 Rotating the extension arm 95, the separating assembly 85 and the conveying assembly 91 in the direction indicated by the arrow 98, stops the conveying process of the section 81, thereby stopping the filter production process.
[0010] Example VI. In Figure 7 with 8 In the illustrated embodiment, the conveyor 63 in the conveying area 62, the rotating disc cam 66 in the separating assembly 65, the rotating disc 69 and the belt 73 in the conveying area 71 have independent drives, which are not shown in the figure. The measurement of torque in any motor indicates an increase in movement transmitted by section 81 in each zone. In this case, the control system cuts off the drive in this zone and activates the pneumatic cylinder, not shown in the figure, which moves the separation assembly 65 and/or the transfer assembly 91 away, and stops the operation of the section 81 Transfer process, thereby suspending the filter production process.
