Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a device for wrapping loads using a strip of stretch film or the like, and in particular, it involves manually applying stretch film or the like to a load stacked on a pallet. This relates to a portable handle wrapper that can be twisted and stretched while being wrapped.

[Conventional technology] With the advent of the era of mass logistics, pallet transportation is expected to further expand as sheet pallets become more widespread, and a number of measures have been taken to prevent cargo collapse, which is an important problem in pallet transportation. There is. Stretch packaging is an effective way to prevent cargo from collapsing. Usually, stretch packaging involves placing the cargo on a turntable and applying tension to the film that is unwound as the cargo rotates. This is a method in which cargo is wrapped in pallets using stretch film, and the cargo and pallets can be firmly tied together using stretch film.It is suitable for large cargo, and most pallets are now packed using this method. is generally adopted.

One feature of this stretch packaging is that it applies a brake to the film material to generate tension for film stretching (for example, an electromagnetic brake,
(powder brake, various other friction bar braking methods, etc.), and packaging methods include the so-called turntable method, which generates stretching force by rotating the cargo while the brake is applied. On the other hand, a method was developed in which there was no need to move the pallet load, and a motion-controlled robot ran around the pallet load to wind up the film.

These wrapping devices are classified based on the type of wrapping machine, and are standard types that insert the tip of the stretch film into the cargo placed on a turntable, press the start button, and complete automatic wrapping according to the set number of wraps. A fully automatic type that stops the cargo moving on a roller conveyor at the center of the turntable, completes packaging according to the set number of wraps, cuts the film, seals the end of the film, and moves it downstream on a roller conveyor. It was from.

[Problems to be solved by the invention] However, as is clear from the above, the equipment used in the conventional stretch film packaging method is large and complicated, and requires incidental equipment, which increases equipment costs. There were flaws.

[Means for Solving the Problems] The present invention was devised in consideration of the above-mentioned conventional drawbacks, and it provides a handler part for winding a belt-shaped material wound around a winding core around a loaded object while unwinding it from the winding core. A first receiving member for receiving one end of the winding core, a second receiving member for receiving the other end of the winding core, a shaft for supporting these first and second receiving members, and at least one of the shafts. a handle that supports one end; a spring that presses the first and second receiving members against the winding core; an adjustment member that adjusts the pressing force of the spring;
and a rotation preventing member that prevents rotation of at least one of the receiving members.

[Function] In the present invention, constant tension is always applied to the strip by the pressing force of the spring, and the pushing force of the spring can be adjusted, making it possible to set the tension of the strip to a desired value. .

[Example] Next, the present invention will be explained in detail based on the example shown in FIGS. 1 to 4.

In the figure, reference numeral 1 denotes a hand wrapper, which rotatably attaches a stretch film roll A on which a stretch film (strip material) b is wound around a paper tube (core) a, and pulls out the stretch film b. It is possible.

Reference numeral 2 denotes a U-shaped handle, which is composed of an L-shaped handle body 20 and an arm portion 21 that is inserted into and taken out from the end of the handle body 20, and the arm portion 21 is telescopically connected. This is what is being done.
Reference numeral 3 denotes a shaft, which is erected on a bottom plate c fixed to the other end of the handle main body 2, and has a threaded end and a screw member (adjustment member) 4 screwed into the shaft. Further, a lower plate 5 fixed to the handle body 20 is located at the base of the shaft 3.

6 is an upper disk (first receiving member), and 7 is a lower disk (second receiving member), each of which is inserted into both ends of the paper tube a of the stretch film roll A. The shaft 3 is inserted through the holes in the upper disk 6 and the lower disk 7. Moreover, the upper disk 6 and the lower disk 7 are paper tubes a
It is not firmly inserted into the paper tube a, but is slidably connected to the opening periphery of the paper tube a, and rotatably supports the paper tube a, that is, the stretch film roll A. Note that 70 is a locking pin provided on the lower disk 7, and the locking pin (rotation preventing member) 70 locks on the lower plate 5 to prevent the lower disk 7 from rotating.

Reference numeral 8 denotes an upper plate fixed to the tip of the arm portion 21, which, as shown in FIG. Locking pin (rotating member)
80. 9 is a spring,
It is interposed between the upper plate 8 and the upper disk 6 and presses the upper disk 6 downward.

In the handler par with the above structure, in order to replace the stretch film roll, the stretch film roll A can be replaced by removing the screw member 4, and then removing the arm portion 21, the spring 9, and the upper disk 6. A new stretch film roll is inserted into the shaft, the upper disk 6 is attached, and the upper plate 8 is attached to the shaft 3 protruding from the upper disk 6 via the spring 9 (the arm 21 is connected to the handle body 20). ), it is only necessary to tighten it with the screw member 4.

When packaging using the above-mentioned handle wrapper, by tightening the screw member 4, the upper plate 8 presses the upper disk 6 downward via the spring 9, and this upper disk 6 becomes a stretch film. The paper tube a rotates as the paper is pulled out.
The rotation of the paper tube a is regulated by being pressed against the paper tube a. That is, a braking force is applied to the rotating paper tube a, and tension is applied to the stretch film to be drawn out, causing it to stretch. and the upper disk 6
Since the locking pin 80 does not rotate, the spring 9 also does not rotate, and as a result, there is no change in the pressing force caused by the intermittently rotating spring, so a constant tension can be applied to the stretch film. This is possible. Further, since the pressing force of the spring 9 can be changed by the screw member 4, the tension of the film can be adjusted to a desired value.

In the handle of the handler tupper, the arm part may be connected to the upper end of the handle body via a pin so as to be rotatable in the vertical direction.
As shown in the figure, a pin e provided on the arm section 22 is engaged with a long hole d at the upper end of the handle body 20, so that the arm section 22 is movable in the vertical direction and rotatably connected. Good too. Further, as shown in FIG. 4, a short stay 23 is rotatably provided at the upper end of the handle body 20, and a long hole g is provided in the arm portion 24, and the pin f of the stay 23 is moved into the long hole g. By freely locking the arm portion 24, the arm portion 24 can be made vertically movable and rotatably connected.

[Effects of the invention] As explained above, according to the invention, it is possible to always apply a constant tension to the strip by the pressing force of the spring, and it is also possible to adjust the pressing force of the spring, so that the tension of the strip can be adjusted. can be set to a desired value. Therefore, the baggage can be packed with the simple operation of holding the handle with your fingers, pulling out the strip from the core, and wrapping it around the loaded load, making it extremely easy to handle, and moreover, it can be carried anywhere as needed. It has excellent practical effects, such as being able to be carried freely anywhere.
