Device for the connecting of strips
The invention relates to a device ( 100 ) for the connecting of strips to an endless strip with a clamping arrangement ( 110, 120 ) with a clamping device ( 110 - r, 120 - r ) on the inlet side and a clamping device ( 110 - l, 120 - l ) on the outlet side, a cutting arrangement ( 155 ) with an upper cutter ( 150 ) and a lower cutter ( 130 ) and with a joining arrangement, in which at least the clamping device ( 110 - r, 120 - r ) on the inlet side and/or the clamping device ( 110 - l, 120 - l ) on the outlet side is constructed as a premountable unit.
1. A device ( 100 ) for connecting separate strips in an endless strip, comprising:
a first clamping device provided on an inlet side of the connecting device for clamping one separate strip and a second clamping device provided on an outlet side of the connecting device for clamping another separate strip, the first clamping device and the second clamping device each having an upper clamp ( 110 - r , 110 - l ), a lower clamp ( 120 - r , 120 - l ), and means (H 1 , H 2 , H 3 ) for displacing the upper clamp ( 110 - r , 110 - l ) and the lower clamp ( 120 - r , 120 - l ) between an open position in which a strip can be freely displaced therebetween, and a closed position in which the strip is clamped therebetween, and the first clamping device and the second clamping device each being formed as a separate unit releasably mountable into the connecting device;
cutting means ( 155 ) located between the first clamping device and the second clamping device for cutting ends of the one strip and the another strip; and
joining means ( 183 ) for connecting the one strip and the another strip with each other;
a frame ( 340 );
a first lifting and positioning device ( 400 ) and;
a second lifting and positioning device ( 500 ),
both supported on the frame for supporting the first clamping device and the second clamping device and for adjusting their respective height and lateral positions.
2. The device according to claim 1 , wherein the cutting means ( 155 ) has upper cutting means ( 150 ) and lower cutting means ( 130 ).
3. The claim according to claim 2 , wherein the lower cutting means ( 130 ) is releasably secured in a frame ( 300 ) of the connecting device, and the upper cutting means ( 150 ) is displaceable in a controlled manner at least vertically.
4. The device according to claim 1 , comprising means (H 8 , H 9 , H 10 , H 11 ) for laterally displacing of the first clamping device and the second clamping device toward each other, whereby the cut ends of the one strip and the another strip move toward each other.
5. The device according to claim 1 , comprising at least one welding table ( 170 ) movable under the strip.
6. The device according to claim 5 , wherein the cutting means ( 155 ) comprises two cutting devices ( 130 - r , 150 - r ; 130 - l , 150 - l ); and wherein the first and second clamping devices and the two cutting devices are arranged substantially symmetrically with respect to each other.
7. The device according to claim 1 , further comprising means ( 170 - r , 170 - l ) for brining the cut ends of the one strip and the another strip in contact with each other.
8. The device according to claim 1 , wherein the displacing means comprises a lever arrangement (H 1 , H 2 ).
9. The device according to claim 7 , wherein the bringing means comprises a first table ( 170 - r ) and a second table ( 170 - l ) displaceable in a position in which the one strip and the another strip contact each other, the first table ( 170 - r ) and the second table ( 170 - l ) forming part of the first clamping device and the second clamping device, respectively.
10. The device according to claim 9 , wherein the first clamping device and the second clamping device each comprises means for displacing the tables into a position in which the one strip and the another strip contact each other.
11. The device according to claim 10 , wherein the table displacing means comprises two rocker-arms ( 171 , 172 ) and a fluid cylinder (H 12 ) for displacing the rocker arms.
12. The device according to claim 8 , wherein the first clamping device and the second clamping device each comprises a fluid cylinder for displacing the lever arrangement between the open and closed positions of the upper clamp ( 110 - r , 110 l ) and lower clamp ( 120 - r , 120 - l ).
13. The device according to claim 1 , wherein the first and second clamping devices are releasably secured to the first and second lifting and positioning devices.
