The present invention overcomes the foregoing and other

shortcomings and drawbacks of traditional turntable assemblies utilized in stretch wrapping models. As the innovation will probably be defined in experience of certain embodiments, it will be realized that this technology will not be limited by these embodiments. To the contrary, the technology consists of all choices, changes, and equivalents as may be integrated in the spirit and scope from the existing innovation.

[0009] According to one aspect of the present invention, a turntable assembly for a stretch wrapping machine comprises a frame, a turntable mounted to the frame for rotation about a generally vertical turntable axis of rotation, and a plurality of rollers rotatably mounted to the frame and defining a generally horizontal supporting plane for supporting the turntable. Each of the plurality of rollers has an axis of rotation normally parallel towards the supporting airplane and usually moving with the turntable axis of rotation. The structure is built of your material and also a geometry to be able to elastically deform, on a lot getting positioned after the turntable that contributes to the burden not being uniformly backed by the rollers, to allow the axis of rotation of a minimum of one roller from the plurality of rollers to tilt relative to the horizontal supporting plane although continue to moving with the turntable axis of rotation.

[0010] The plurality of rollers can make up a plurality of sets of rollers, each kind of rollers of your plurality of pairs of rollers being mounted on a particular body an affiliate the frame such that a single roller of your pair of rollers is situated in one part of the structure associate and also the other curler in the couple of rollers is situated on the opposite side in the frame fellow member. In a single embodiment, each and every body participant may be constructed in a way that the deflection below stress circumstances will never exceed the generate durability of your material of the body participant. Each and every framework participant could be constructed of your material as well as a geometry in an attempt to elastically deform an quantity enough to permit the curler combine axis of rotation to lean about 3 degrees every time a weight around 3,500 lbs is placed on one roller in the couple of rollers. For instance, each framework associate may be generally rectangular in go across section using a elevation of approximately 2. ” and a width of about .25 inches, and will be constructed of A36 stainlesss steel. The set of rollers may be situated normally midway along a length of the structure fellow member. If desired, the frame member can have a reduced height between the pair of rollers and each end of the frame member. On the other hand the set of rollers might be located close to 1 end from the frame participant, and the body associate can have a decreased size at the end close to which the kind of rollers is located. [0011] In an additional part of the present technology, a turntable set up for a stretch wrapping machine includes a frame, a center rotatably installed towards the body with a shaft, and a turntable installed towards the center for rotation about a normally straight turntable axis of rotation. The body includes hub deflection reducing composition spread out around the turntable axis of rotation at about degrees, at about 90 degrees, and at about 180 degrees. If the turntable is struck causing the hub to bend the shaft, the shaft will elastically deform rather than plastically deform, the deflection limiting structure is spaced from the hub by an amount such that.
