Description: Apparatus for assembling of angle plates on the flanges of ventilation ducts The subject of invention is an apparatus for assembling of angle plates on the flanges of ventilation ducts. Invention is known from United State Patent No.: 5 283 944 as the apparatus for placement of angle plates in transverse duct flanges comprising platen for placing of the ventilation duct, blocking device for blocking the duct in preselected position, advancing device moving the angle plate into engagement with a corner of blocked ventilation duct and pressing device for pressing of angle plate into duct flange. The angle plate advancing device in said invention comprising slider for sliding of the lowest angle plate from angle plate stack in the supply hopper and moving it to the ventilation duct. The angle plates moved from the stack must be shaped in the way that their sliding does not create too much resistance. An apparatus for assembling of angle plates on flanges of ventilation ducts comprising platen with the ventilation duct blocking device, angle plate advancing device with the slider and angle plate supply hopper, pressing device for pressing of an angle plate in the ventilation duct flanges and ventilation duct flange crimping device in accordance with this invention characteristic of that angle plate advancing device comprise two arms movable carrier and slider. The carrier stays on the base plate. There is an angle plate supply hopper over the carrier. The slider has an oblong slot and socket and is moving in the guide located in the lower part of base plate and on slider working plane performing to-and-fro motion forced by fluid motor piston rod which has stable joint with slider. The slider working plane has a furrow which width is smaller then angle plate arms spun. The base plate has an angle plate shape port and oblong hole with long axis parallel to slider movement direction. There is a pilot stably fixed to the front part of base plate located close over furrow in the slider working plane. The pilot is used for rising of the angle plate arms when it is advanced into ventilation duct corner. The carrier arms have oval holes at the ends where the rest buttons stably fixed to the base plate are installed. The carrier oval holes long axis are parallel to the slider movement. In the center of the carrier there is stably fixed carrying pin located in base plate oblong hole and the slider oblong slot. The carrier arms are finished with the shaped catches sliding the lowest angle plate out of the supply hopper. The catches with the internal parts of carrier arms are shaped like external part of the angle plate but their dimensions are slightly bigger then angle plate. The carrier is shifted by slider only at the last parts of its to-and-fro movement. The angle plate supply hopper in the top view has an angle bar shape with the arms separated a little more then 90° and with the edges bent out twice. The angle plates stacked in the supply hopper are supported on the carrier during the time of assembling cycle. The invention subject is the universal apparatus. It can be applied for different shape of angle plates because of the angle plate catching is performed by suitably shaped carrier catches. The apparatus operation enable correct and stable the angle plate assembling in the ventilation duct flanges. The subject of invention is presented on the drawing where fig. 1 - presenting an apparatus side view, fig. 2 - an apparatus top view, fig. 3 - top view of a carrier in slider extreme positions, fig. 4 - cross-section of a carrier with a slider front position. The apparatus as a subject of invention comprising the ventilation duct .3 blocking device 2 installed on the platen 1, the angle plate 5. advancing device 4., pressing device 6 for pressing of the angle plate 5 in the ventilation duct 3 flange 7 and crimping device 8. for crimping the ventilation duct 3 flange 2 on the angle plate 5 edges. The angle plate 5 advancing device 4. comprising two arms carrier 9_ and slider 10. There is the angle plate 5. supply hopper U over the carrier 9_. The slider IfJ is sliding in the guide 2J5 located in the lower part of the base plate 19. and on the slider 10 working plane H. The slider .10 is stably joined with the piston rod 15 of fluid motor 16. The carrier 9_ is located on the base plate 19. The slider 10 working plane 14. has a furrow 26.. There are port 22 and oblong hole 21 in the base plate 19. In the front part of the base plate 19 the pilot 2A is fixed it is located over the furrow 26. in the slider 10 . working plane U . . The carrier 9. arms at ends have an oval holes 12 where the rest buttons 18 stably fixed to the base plate 19 are installed. There is a carrying pin 2Q fixed to the central part of the carrier 9 . The carrying pin 20 is placed in the oblong hole 1 of the base plate and oblong slot 12 of the slider 1Q_. The carrier 9_ arms are ended with the catches 22. The operation of the apparatus according to invention - starts from filling of the supply hopper H with the angle plates 5 and from placing the ventilation duct 3 on the platen 1 - When the apparatus is switched on the blocking device 2 sets up and blocks ventilation duct 3 in proper place for full time of assembling cycle. When the ventilation duct is blocked the advancing device 4. starts its operation. The fluid motor 16. piston rod 1_5 which is stably fixed to the slider 10 starts moving back from the ventilation duct 3.. When the slider JLQ front edge of slot 12 contacts the carrying pin 2Q stably fixed on carrier 9. at the same moment the slider 10. and the carrier 9. start their movement back. The carrier 9_ arms catches 22. catch the lowest angle plate 5 stocked in supply hopper H and move it to the base plate 19 port 23. The angle plate 5 drops down through the port 1 to slider 10. working plane 14 until its corner gets the slider 10. socket 12. The fluid motor 16 piston rod 15 changes its movement direction at the same time. The slider IP. moves the angle plate 5 on the working plane 14. into the ventilation duct 2. The angle plate 5. is moved to the pilot 2 which is fixed in the lower part of base plate 19 over the furrow 26. in the slider 0 working plane 14.. The pilot 24. presses the angle plate 5. corner causing the rising of its arms. When the slider 10 back edge of slot 12 contacts with the carrier 9. carrying pin 20 the carrier 9 and the slider 10 start their forward movement. The carrier 9_ is moved under the angle plate 5. supply hopper 11 and at the same time slider 10 places the angle plate 5 with the raised arms over the channel bar flanges 2 of the ventilation ducts 2- The presser device is switched on and angle plate 5_ arms are pressed into the channel bar flanges 2 of the ventilation duct 3_. The final operation of angle plate 5 assembling is activating of two crimping devices 8. which crimp the ventilation duct 2 flanges 2 on the angle plate 5. edges.
