The device of orbital stretch wrapping machine 9

[0051]

The present creation as embodied herein and explained previously mentioned, will allow entirely automatic wrapping of lots at a significantly lowered expense as well as in an extremely efficient way. The simplicity from the device and its particular function permits pre-existing rotary stretch wrapping machine being retrofit to become fully automatic. By using the rotation of the turntable to facilitate thereleasing and grasping, and cutting of the packaging material, the need to supply power through the rotatable turntable of the turntable assembly to the packaging material holder and the need for expensive timing circuits is eliminated.

[0052]

It can be planned the present invention deal with all modifications and variations of this creation which come within the range of your appended orbital stretch wrappers.

An approach of wrapping a load (124) with packaging materials (116), comprising:

grasping a respected finish (30) of packaging substance (116) having a packaging substance holder (110) attached to a rotatable turntable (122) and isolated from the electrical or water power source of through the rotatable turntable (122);

dispensing packaging materials (116) coming from a packaging substance dispenser (102) and spinning the turntable (122) to place packaging material (116) round the ends in the stress (124);

automatically releasing the key conclusion (30) from the packaging materials (116) in the packaging fabric owner (11 a): and

instantly grasping a trailing finish (32) from the packaging materials with the packaging material holder (110) with a point upstream of the top finish;

? ?? recognized in that the process includes collapsing the world wide web of packaging fabric (116) before automatically grasping the trailing conclusion (32) of packaging materials (116).

The method of orbital stretch wrapper 1, described because instantly grasping consists of grasping the packaging material (116) with jaws (112,114) and the immediately issuing includes discharging the packaging fabric (116) through the jaws (112,114).

The apparatus of orbital stretch wrapping machine 8

Rotatable turntable stretch wrapping machine starts to swivel and packaging material 116 is dispensed from dispenser 102 about weight 124. As packaging material 116 passes over packaging material holder 110, wheel 41 engages the lower edge of the packaging material, ensuring that the packaging material passes over packaging material holder 110 and does not become caught on it. This eliminates a “tenting” result and permits restricted wrapping in the weight. Fill 124 is spirally twisted with packaging material 116 as dispenser 102 goes up and down coupled mast 104 since the general rotation is supplied.

See Fig, as the load is wrapped and rotatable turntable 122 enters the last rotation of the wrapping cycle. 6, a pin 130 mounted on a non-rotating section of turntable construction 120 is actuated with the control, relocating from your non-up-right placement for an vertical situation. As the turntable 122 rotates, pin 130 engages engaging element 134 of cog 132, located on top of rotatable turntable 122 of turntable assembly 120. Pin 130 triggers cog 132 to advance upstream (inside a route opposing for that of your rotation) over the leading area of rotatable turntable 122 of turntable assemblage 120 as rotation proceeds.

[0044]

As cog 132 moves, the movement causes cam follower 158 to move up onto the top of ramp 150, to the start of downstream path 152. When camera follower 158 moves to the peak of ramp 150, jaws 112, 114 open, instantly issuing top rated end portion 30 of packaging materials 116 (see Fig. 7). Moreover, dispenser of stretch wrapping machine is turn off to tension the film among stress 124 and dispenser 102.

As cog 132 moves, it drives jaws 112, 114 downstream along a downstream path 152 of ramp 150. Concurrently, scooping aspect 140 starts to move from your retracted situation to a upright placement, scooping a trailing conclusion 32 of packaging substance 116 right into a rope 118. As stretch wrapping machine consistently transfer downstream, they keep available, acquiring trailing stop wrapper of packaging materials 116 shaped into rope 118 as scooping component 140 reaches its full erect position (see Fig. 8). As cog 132 reaches the upstream end of packaging material holder 110, cam follower 158 reaches the end of path 152 and rolls off the end of ramp 150, causing jaws 112, 114 to automatically clamp shut on and grasp trailing end 32 of roped packaging material 116.

The apparatus of orbital stretch wrapping machine 8

As embodied herein and demonstrated in orbital stretch wapping machine, a packaging fabric weakener is supplied for weakening the packaging materials 116 involving the stress 124 and the dispenser 102. The packaging materials owner 110 ideally includes a cutter 142. Cutter 142 could include an compared decreasing element, including scissors, or possibly a single reducing factor say for example a razor blade. Cutter 142 is connected to an actuation handle 144 which techniques with jaws 112, 114. Actuation handle 144 is moveable between a cost-free place along with a contact situation. As jaws 112, 114 move along downstream path 152, jaws 112, 114 open, automatically releasing packaging material 116, scooping element 140 moves upward to scoop the lower edge of the web of packaging material 116 into a rope 118, and actuator lever 144 moves from the free position to the contact position. When actuation lever 144 is with the contact place, cutter 142 is activated to weaken packaging fabric 116 by decreasing a minimum of a part of the website of packaging material 116, like the rope 118 of packaging material 116.

The apparatus may include means for securing a trailing end of packaging material to the load, according to one aspect of the present invention. As embodied herein, the means for securing includes a film wipedown mechanism for wiping a film tail onto the load after the packaging material has been cut. As demonstrated in Fig. 1, the film wipedown mechanism 180 involves wash loops 182 and a wipe left arm 184. This enables a film tail to become washed on fill 124 as the packaging material 116 is minimize.

Other cutters and wipedown preparations could also be used.

A method for wrapping a load according to the present invention is shown in Figs. 5 – 11. As displayed in Fig. 5 and according to a preferred embodiment of the present invention, a load 124 is conveyed by a conveyor 118 to a turntable assembly 120 in the wrapping station and load 124 is positioned on top of rotatable turntable 122 of turntable assembly 120. Jaws 112, 114 of packaging substance holder 110 keep a major stop segment 30 of the roped sheet of stretch wrapping packaging materials 116, preferably stretch cover packaging material. Cog 132 is located at a downstream conclusion of packaging material owner 110, and jaws 112, 114 are positioned in the upstream finish of packaging material owner 110, and cam follower 158 is located towards the upstream part of ramp.

The equipment of orbital stretch wrapping machine 6

[0031]

Packaging material holder 110 is mounted on the top surface of rotatable turntable 122, and jaws 112, 114 of packaging material holder 110 are actuated to automatically open and close at predetermined points along the length of ramp 150 of packaging material holder 110, as discussed above. As embodied herein, packaging material holder 110 is isolated from any electrical or fluid source of power by the turntable, in contrast to conventional devices in which the packaging material holder is connected to an electrical or fluid source of power by the turntable such as by a power connection through the journal of the turntable to the packaging material holder. Which means that the packaging material owner also does not obtain any electric powered or fluid energy from brushes, or perhaps the like, around a circumference in the turntable. The rotatable turntable 122 therefore fails to hold electric or substance power sources by using it during rotation and acts as a buffer involving the packaging materials owner as well as electric or liquid supply of strength.

[0032]

This enables the current innovation to benefit from the changing from the perspective of your packaging substance relative to the load as the turntable rotates. The rotation of the turntable is harnessed to linearly move the packaging fabric holder along the turntable area. During the last rotation of the turntable orbital stretch wrapper , because the angle becomes smaller and also the packaging material techniques one side from the load, the packaging materials holder is driven from the rotation in the turntable into a position to take part the trailing stop in the packaging substance.

[0033]

In the favored embodiment, as displayed in Fig. 2, the motion of your turntable is utilized to maneuver jaws 112, opening, 114 and closing stretch wrapping machine to automatically release and understanding, respectively, packaging fabric 116. As discussed above, cog element 132 cooperates with pin 130 to move jaws 112, 114 relative to rotatable turntable 122 and thereby open and close jaws 112, 114. Pin 130 may be actuated to advance through the no-vertical place for the up-right situation in a predetermined point in the wrapping routine with the control. If possible, pin 130 is actuated during the last rotation in the wrapping pattern, and a lot ideally over the past quarter transform in the wrapping period, to engage cog 132. Because cog 132 moves with rotatable surface 122 of turntable 120, the rotation of the turntable can be used to move cog 132. If cog 132 moves to the left, jaws 112, 114 will move to the right, Cog 132 is moveably connected to jaws 112, 114 such that. Alternatively, if cog 132 is moved to the right, jaws 112, 114 will move to the left. Thus, this is the rotation from the turntable, as opposed to a power or substance power source transported through the spinning turntable, which is used to advance and thus instantly close and open stretch wrapping machine.

[0031]

As discussed above, packaging material holder 110 is mounted on the top surface of rotatable turntable 122, and jaws 112, 114 of packaging material holder 110 are actuated to automatically open and close at predetermined points along the length of ramp 150 of packaging material holder 110. Packaging material holder 110 is isolated from any electrical or fluid source of power by the turntable, in contrast to conventional devices in which the packaging material holder is connected to an electrical or fluid source of power by the turntable such as by a power connection through the journal of the turntable to the packaging material holder, as embodied herein. This means that the packaging fabric owner also does not get any electric powered or fluid potential from brushes, or the like, close to a circumference from the turntable. The rotatable turntable 122 as a result does not bring electrical or fluid energy sources along with it while in acts and rotation like a obstacle involving the packaging substance owner and any electric or liquid method to obtain potential.

[0032]

This lets the current invention to benefit from the transforming of the perspective of your packaging material in accordance with the stress as the turntable rotates. The rotation of your turntable is harnessed to linearly transfer the packaging fabric holder across the turntable work surface. During the last rotation from the turntable orbital stretch wrapper , as being the position gets to be smaller sized and also the packaging material techniques along side it of your load, the packaging fabric holder is pushed by the rotation of the turntable into a place to interact with the trailing end of the packaging material.

[0033]

Inside a recommended embodiment, as proven in Fig. 2, the motion from the turntable is commonly used to move jaws 112, 114, closing and opening stretch wrapping machine to immediately launch and grasp, correspondingly, packaging fabric 116. Cog element 132 cooperates with pin 130 to move jaws 112, 114 relative to rotatable turntable 122 and thereby open and close jaws 112, 114, as discussed above. Pin 130 might be actuated to go in the no-vertical situation on the upright situation at the predetermined part of the wrapping period with the controller. Ideally, pin 130 is actuated during the last rotation from the wrapping cycle, and most if at all possible during the last quarter transform of your wrapping pattern, to interact with cog 132. The rotation of the turntable can be used to move cog 132, because cog 132 moves with rotatable surface 122 of turntable 120. Cog 132 is moveably connected to jaws 112, 114 such that, if cog 132 moves to the left, jaws 112, 114 will move to the right. Alternatively, if cog 132 is moved to the right, jaws 112, 114 will move to the left. Hence, it is the rotation in the turntable, rather than a power or substance power source transported with the turning turntable, that is used to move and thus automatically open and close stretch wrapping machine.
