Patent number: 4906163Abstract: The stacking machine for making stacks of adjacent disk-like workpieces, e.g. metal covers, has a conveyor trough along which a column of workpieces being divided into stacks moves in its longitudinal direction until the stacks reach an unloading station. To maintain a space between successive stacks spherical spacers are inserted between the stacks into a gap formed there by the feed mechanism. A return trough inclined to the conveyor trough running from the unloading station to the feed mechanism is provided for feed back of the spherical spacers. This return trough may be mounted beside or below the conveyor trough. Only a very minimal construction expense is necessary to maintain the gap between the stacks and to feed back the spherical spacers which is effected because of the action of gravity alone.Type: GrantFiled: March 9, 1989Date of Patent: March 6, 1990Assignees: Schmalbach-Lubeca AG, Eberhard HalleInventors: Jurgen Muller, Eberhard Halle

Patent number: 4869359Abstract: The apparatus for forming separate piles of equal-numbers of workpieces, especially can covers, from a stack moving longitudinally in a feed trough is equipped with an electronic counter and controller with a sensor responding to the edge of the workpiece which operates without contact with the workpiece and with a feed device which is shiftable into a clamped and a released position engaged on the stack upstream of the sensor in the feed direction. It is drivable in the clamped position with at least two feed speads. Moreover a separating mechanism is provided with a separating wedge movable to-and-fro transverse to the stack to form a separating gap in the edge region between the adjacent workpieces of the pile and the stack together with two separating knives guidable into the separating gap which are connected with a drive acting in the longitudinal direction of the stack. The new apparatus can be mounted at each position along the conveying trough without interruption of or blocking the trough.Type: GrantFiled: July 8, 1988Date of Patent: September 26, 1989Assignees: Schmalbach Lubeca AG, Eberhard HalleInventors: Jurgen Muller, Eberhard Halle

Patent number: 4842887Abstract: At least one complete surface of at least one metallic part of a can is given a uniform coating of corrosion-preventing lacquer and this part is subsequently worked such that the metal of the part is exposed at regions at least immediately adjacent the coated surface. Dots of lacquer are sprayed by the ink-jet method substantially only on the exposed regions of the part after working thereof and so that the dots together form a continuous layer covering the exposed regions. According to the viscosity of the lacquer the surface coating can be achieved by partially overlapping adjacent dots of the applied lacquer or without overlapping by the running together of the adjacent dots of the liquid, with no excess material having to be applied to and subsequently removed from the regions to be coated.Type: GrantFiled: June 15, 1988Date of Patent: June 27, 1989Assignee: Schmalbach-Lubeca AGInventor: Georg Bolte

Patent number: 4752172Abstract: The apparatus of the invention provides a coat of lacquer or varnish on a tear-off cover, which is formed from a thin ferromagnetic metal, has a circumferential supporting lip and is equipped with a tear-off opening made by scoring and/or punching in or out the cover surface. To provide the coat of lacquer or varnish the cover is moved through an electric coating tank, a washing tank and drying zone with the plane of the cover oriented substantially vertically while being supported exclusively on the surface of the inner wall of the supporting lip. The entire surface of the cover is completely covered by the lacquer or varnish coating except for a small portion on the inner wall of the supporting lip which is positioned inside the closed container in a folded seam and/or covered by a sealing material.Type: GrantFiled: August 14, 1987Date of Patent: June 21, 1988Assignee: Schmalbach-Lubeca AGInventor: Georg Bolte

Patent number: 4740284Abstract: The holding device for conveying container bodies open at both ends made of ferromagnetic material on a conveyor has at least one permanent magnet for generating magnetic forces necessary to hold the container body on it, a supporting member attachable with the conveyor and two framework components (one of which may be made slidable) held spaced from each other aligned in the longitudinal direction of the supporting member. Alternatively in two specific examples of our invention the permanent magnet is provided in the vicinity of the framework components and the supporting member is insertable in the container body or the permanent magnet is provided on the supporting member or it is the supporting member and an electrode distinct from the supporting member is insertable in the container body. The framework members have a substantially U-shape cross section and are arranged so that their free side pieces on each side thereof parallel the longitudinal direction of the supporting member.Type: GrantFiled: June 24, 1987Date of Patent: April 26, 1988Assignee: Schmalbach-Lubeca AGInventors: Georg Bolte, Hartmut Helbing

Patent number: 4693801Abstract: A decor is applied to a tin can by printing a pattern onto a metallic surface thereof directly and hardening the pattern on the metallic surface. The can is then immersion-coated in an electroimmersion lacquering unit to provide it with a lacquer coating. The printed pattern can be an electrically conductive lacquer in order to insure the electroimmersion coating of the printed pattern as well as the exposed metal surfaces which may surround it.Type: GrantFiled: July 9, 1985Date of Patent: September 15, 1987Assignee: Schmalbach-Lubeca AGInventor: Georg Bolte

Patent number: 4676366Abstract: A holding device for gripping and retaining containers, including can bodies or cans which have one open end, during transport on conveyers, includes a planar carrier which can be connected at the conveyer chain or forms part thereof. A plurality of clamp elements is secured at the carrier. The clamp elements are made of resilient material, and they are fastened for clamping or snap-like retention of the container bodies at diametrically opposite locations respectively in pairs at the carrier. The clamp elements of each pair have respectively crossing adjacent sections, and the inner clamp is adapted to operatively contact the peripheral edge of the respective retained container. The outer clamp is adapted to operatively engage the outer wall surface of the container rim which is directed towards the carrier.Type: GrantFiled: September 30, 1985Date of Patent: June 30, 1987Assignees: Schmalbach-Lubeca AG, Eisenmann Maschinenbaugesellschaft mbHInventors: Georg Bolte, Helmut Schwarz
