Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
158 words
An apparatus for producing sheet metal plates having reinforcing members welded thereon, comprising a transport device for the sheet metal plates and device for holding the reinforcing members in a substantially upright position on the sheet metal plates prior to welding, said holding device including clamping means arranged in stationary manner in a mounting station for holding said reinforcing members on said plates, a feed device comprising means for horizontally moving the reinforcing members, stationary transverse guide means located adjacent the feed path of the sheet metal plate and extending transversely to the direction of feed of the sheet metal plate, through which said reinforcing members are moved by said means for horizontally moving, whereby said reinforcing members, after leaving the transverse guide, slide over the sheet metal plate and reach their mounting position, welding means being provided at said holding device for welding said reinforcing members to said sheet metal plates while secured by said holding device.
Claim 2
Independent Claim
158 words
An apparatus for producing sheet metal plates having reinforcing members welded thereon, comprising a transport device for the sheet metal plates and device for holding the reinforcing members in a substantially upright position on the sheet metal plates prior to welding, said holding device including clamping means arranged in stationary manner in a mounting station for holding said reinforcing members on said plates, a feed device comprising means for horizontally moving the reinforcing members, stationary transverse guide means located adjacent the feed path of the sheet metal plate and extending transversely to the direction of feed of the sheet metal plate, through which said reinforcing members are moved by said means for horizontally moving, whereby said reinforcing members, after leaving the transverse guide, slide over the sheet metal plate and reach their mounting position, welding means being provided at said holding device for welding said reinforcing members to said sheet metal plates while secured by said holding device.
Claim 3
Dependent Claim
42 words
An apparatus as claimed in claim 1, wherein the feed device for horizontally moving the reinforcing members comprises a slide member which is movable along the transverse guide and has a lug adapted to engage the trailing end of the reinforcing member.
Claim 4
Dependent Claim
48 words
An apparatus as claimed in claim 2, wherein the transverse guide comprises a channel section provided at its bottom with supporting rollers and at its sides with lateral guide rollers for the reinforcing member, the latter being adapted to be inserted from above into the said channel section.
Claim 5
Dependent Claim
29 words
An apparatus as claimed in claim 3, wherein supporting rails for the slide member are provided halfway up to the guide channel section and in the side walls thereof.
Claim 6
Dependent Claim
38 words
An apparatus as claimed in claim 1, wherein said the clamping means is provided with a bridge freely extending above the entire width of the sheet metal plate, groups of adjustable clamping members being disposed on said bridge.
Claim 7
Dependent Claim
26 words
An apparatus as claimed in claim 5, wherein the clamping means includes a group of downwardly acting holding members and a group a laterally-acting holding members.
Claim 8
Dependent Claim
17 words
An apparatus as claimed in claim 6, wherein the downwardly-acting holding members consist of hydraulically actuated plungers.
Claim 9
Dependent Claim
31 words
An apparatus as claimed in claim 6, wherein the laterally acting holding members are provided with pairs of oppositely movable clamping elements which engage on both sides of the reinforcing members.
Claim 10
Dependent Claim
36 words
An apparatus as claimed in claim 8, wherein the laterally-acting holding members are arranged on slide members which are capable of travelling upwards and downwards, are forked in their lower region, and engage the reinforcing member.
Claim 11
Dependent Claim
29 words
An apparatus as claimed in claim 9, wherein the laterally acting holding members are connected together by continuous support members which interconnect the arms of the forked slide members.
Claim 12
Dependent Claim
49 words
An apparatus as claimed in claim 10, wherein a beam-shaped abutment is arranged within the feed path for the sheet metal plate, said abutment being adjustable in its height by means of wedges which are arranged on its underside and are provided with drive means for their horizontal displacement.
Claim 13
Dependent Claim
78 words
An apparatus as claimed in claim 10, with a welding carriage movably arranged on the bridge of the clamping device, wherein two separate drive motors are provIded to which a drive mechanism shaft is alternately connectable by means of clutches, one of said motors being a variable speed DC drive motor for effecting a variable speed movement during welding, and the other being a sliding armature motor for effecting a rapid movement from and to the welding point.
Claim 14
Dependent Claim
54 words
An apparatus as claimed in claim 10, with a welding head which is adjustable in height and laterally, wherein the welding head is carried by a first, substantially vertical, linear piston drive, whose other part is carried with the movable part of a second, substantially horizontal, linear piston drive secured to the welding carriage.
Claim 15
Dependent Claim
17 words
An apparatus as claimed in claim 13, wherein the welding head is provided with a roller guide.
Claim 16
Dependent Claim
15 words
An apparatus as claimed in claim 13, wherein the linear piston drives are operated pneumatically.
Claim 17
Dependent Claim
30 words
An apparatus as claimed in claim 13, wherein the welding head only rests with part of its weight on a support being provided with a pressure relief device acting thereon.
Claim 18
Dependent Claim
70 words
TAn apparatus as claimed in claim 16, wherein the vertical linear piston drive constituting the pressure relief device for the welding head, is subject to different pressures when travelling upwards and when travelling downwards, both these pressures being upwardly directed and of a magnitude such that the pressure difference between the hydraulic or pneumatic pressure and the gravitational force of the welding head is alternately positive (upward travel) and negative.
Claim 19
Dependent Claim
80 words
An apparatus as claimed in claim 17, wherein the vertical linear piston drive is connected to a one-way valve, which is adapted to be switched between two supply ducts leading from the pressure medium source and wherein one of the said supply ducts, provided for downward travel into the welding position, contains a pressure reducing device and the other supply duct, which is provided for upward travel, incorporates a slide valve adapted to be switched on or off as required.
