Stretch wrapping apparatus and method

A stretch wrapping apparatus is adapted for use with an automated palletizing machine to securely stabilize loads prepared by the palletizing machine. The stretch wrapping machine works with a rotatable turntable on which the palletized load is placed. A stretch wrapping head feeds pre-stretched wrapping film toward the rotating load and air jets blow the tail of the film onto the load. Relative rotational movement is created between the wrapping head and the load and the free end of the film is unsupported by any mechanical structure and is directed toward the load only with air from the jets. The film attaches to an outer surface the load and the wrapping head moves vertically so that the load is helically wrapped. Film is dispensed at a rate to provide payout of film that is consistent with the demand as each load corner transitions through its relative distance change from the dispensing point based on calculations intervals. A sensor detects changes in the optical character of the filmdefectsto determine an out of bounds condition such as a film break. A film cutter arm assembly uses a hot wire and press rolls to cut the film when the load is wrapped.

Coil packaging system

Packaging mattresses as a double spiral roll
10597185 · 2020-03-24 · ·

Mattresses are packaged by successively rolling two compressed mattresses into a roll in which a rolling wrapper forms a spiral when viewed from an end of the roll. The bottom surface of a first mattress is placed on the wrapper such that the wrapper wraps around a first end of the mattress. The first end is then inserted between the bars of a mechanical roller. The first end is bent over onto the top surface of the mattress, and the mattress is rolled. The bottom surface of a second mattress is placed on the wrapper, and the first mattress is further rolled until successive portions of the bottom surface of the first mattress become adjacent to successive portions of the top surface of the second mattress. The wrapper is cut, and a first location near the cut edge is taped to a second location one revolution earlier on the wrapper.

The invention relates to a wrapping machine for wrapping a load with a film including at least one operating unit for performing operations on the load or on the film and a conveying device for moving the load along an advancing direction through the machine. The machine includes a movement system that is adapted for moving the operating unit and comprises a shuttle assembly movable along a path and arranged for supporting and moving the operating unit. The shuttle assembly and the conveying device are drivable in a coordinated manner in order to enable the operating unit to perform operations on the load wrapped with the fi8lm even while the load is moved along the advancing direction and out of the machine.

WRAPPING MACHINE WITH IMPROVED CUT, CLAMP, AND SEAM SYSTEM
20200039669 · 2020-02-06 ·

Various embodiments of the present disclosure provide a wrapping machine that includes an improved cut, clamp, and seam system configured to, after film drawn from a film roll has been wrapped around an object, cut the film from the film roll, hold the now-leading end of the film of the film roll, and attach the now-trailing end of the film wrapped around the object to part of the film wrapped around the object.

Walking type winding machine

A walking type winding machine includes a front protection ring being fixed on a steering part and a steering counting device. The steering counting device includes a first sensor for sensing the steering of a machine body, and the first sensor is connected to a controller of the walking type winding machine. The steering part includes a second sensor which is supported by an elastic component such that the second sensor is movably installed on the steering part, and the second sensor is used for sensing the backward movement of the frame of the steering part with respect to the second sensor. The walking type winding machine makes the control of a film winding path become simple and accurate, and it can protect important components of the steering part, improve walking steering sensitivity, and mitigate the impact on the machine body when colliding with an obstacle.
