Abstract:
In a spindle conveyor for conveying workpieces, in particular vehicle wheels, there is a rail system which includes at least one supporting rail. A plurality of transport carriages each have a chassis that is able to move on the supporting rail in a transporting direction and a carrying device for workpieces carried along by the chassis. The carrying device includes at least one workpiece spindle for receiving the workpiece and which is pivotable, at least in a particular section of the spindle conveyor, between a conveying position and a particular position different from the conveying position wherein the workpiece spindle is tilted in the particular position with respect to a vertical plane (V) which extends parallel to the transporting direction. Also, a plant for treating workpieces having such a spindle conveyor which conveys the workpieces through the plant.
Abstract:
To provide a pin tip attachment structure that can engage a container with a bottom, such as a can or bottle, and convey the container without scratching it, a small diameter portion having a predetermined length is formed at a front end portion of a pin. A bushing is fitted in a lower end portion of a cylindrical hole of a pin tip having the cylindrical hole opened at a lower end side, and the bushing is vertically movably inserted onto the small diameter portion of the pin. A stopper portion for retaining the bushing is provided at a front end of the small diameter portion. A spring receiver portion is provided below the small diameter portion, and a coil spring is provided in a compressible manner between the spring receiver portion and the bushing or the lower end of the pin tip.
Abstract:
A system and method is described for treating workpieces, in particular vehicle wheels, especially in the context of a powder coating process, with a conveying device that guides the workpieces along a movement path through the arrangement. The conveying device comprises a conveyor. The workpieces can be arranged on spindle-shaped elements that are secured to the conveyor and that are rotatable about their own axis. The conveyor device comprises at least one means for generating a spatially and/or temporally altering magnetic field, which produces a force to rotate or stop the spindle-shaped elements.
Abstract:
A module for a spiked conveyor belt and a spiked conveyor belt made from these modules, the modules being made of a flexible material and having a substantially flat first surface from which a plurality of space pins protrude; one end of each pin extends from the first surface at an angle of about 60° to the surface; the other end of the pin is mounted in a rib formed on a second surface of the module, the second surface also providing means for hinging the modules together.
Abstract:
A pin oven for curing a decorative or other coating laid down by a rotary decorator on cans has an associated transfer device by which the cans are decelerated and transferred in succession from the decorator onto the chain of the oven. The chain carries two cows of pins which are arranged in staggered and offset relation. By operating at a smaller chain circulating speed than the can output velocity of the decorator, the oven provides benefits in the size and thermal efficiency of the oven and reduced chain wear.
Abstract:
This disclosure relates to a can body transfer mechanism particularly adapted for use as part of an automatic coating and printing machine wherein can bodies and like tubular members are automatically positioned on mandrels and thereafter serially presented to coating and printing blankets. The transfer apparatus includes a vertically disposed feed screw which spaces can bodies and transfers them to a feed turret which, in turn, transfers the can bodies to a transfer turret. The transfer turret has generally horizontally disposed pockets axially aligned with mandrels carried by an endless chain and there is associated with the transfer turret a pusher turret having a plurality of pusher members thereon axially aligned with the turret pockets and the mandrels and automatically operable by a fixed cam in response to the rotation of the pusher turret to push can bodies from the transfer turret pockets onto the mandrels.
Abstract:
An automatic coating and printing machine wherein can bodies and like tubular members are atuomatically positioned on mandrels and thereafter serially presented to coating and printing blankets wherein the necessary coating and printing is effected thereon with the mandrels being rotated as the can bodies carried thereby contact the blankets of the coating and printing cylinders to transfer coating and printing materials to the can bodies. Thereafter, the appropriately coated and printed can bodies are automatically transferred from the mandrels to another conveyor. The mandrels are so mounted wherein when no can body is on a mandrel, the mandrel does not come into contact with the printing or coating blankets. The inking mechanism for the printing machine is designed to apply a uniform coating of ink to the printing drum by a drum inking roll which first has a heavy ink coat applied thereto followed by a second light smoothing ink coat over the heavy coat in advance of the printing drum.
Abstract:
A belly hook attachment is provided. The belly hook attachment has a first support arm, a second support arm spaced from the first arm, the first support arm and second support arm receiving first, second and third pins. A belly hook support arm is carried by the first pin and pivotable about the first pin. A belly hook is carried by the belly hook support arm. A translational member is also carried by the belly hook support arm and is engagable with a track on a conveyor assembly such that the interaction between the track and the translational member results in pivotal movement of the belly hook support arm about the pin between the second pin forming an upper stop and third pin forming a lower stop, thereby moving the belly hook. A modular conveyor belt is also provided.
Abstract:
An improved blow-off system wherein compressed air directed through a nozzle is used to eject individual cans from their support pins, wherein the nozzles move in synchronized manner with the individual cans such that the ejection operation is accomplished without need to stop or slow the processing equipment. The blow-off system has a sprocket, such that the sprocket of the blow-off system can be substituted for an idler or drive sprocket found in the pin chain conveyor system of the processing equipment. Multiple blow-off nozzles are disposed radially from a central distribution manifold, with each nozzle being operated by a dedicated valve. As the cans pass around the sprocket for 90 to 180 degrees, the nozzles are aligned with each can over this entire arc. If a defect is noted such that the can needs to be ejected, the individual nozzle associated with the defective can is activated.
