Description

TECHNICAL FIELD The present invention relates to an apparatus used when packaging (wrapping) a plurality of cardboard packages with a wrap film to prevent collapse of the cargo.

When stacking a plurality of cardboard packages and storing them in a container or the like, it has recently been customary to wrap and wrap them around the waist with a wrap film (stretch) so as not to collapse the cargo. . The wrap film effectively exhibits sufficient adhesiveness and strength only by pressure bonding with each other.

At present, all of the work is performed manually or a dedicated automatic stretch wrapping machine is used, and the latter automatic wrapping machine is used to install and cut the film. The operator performs the rest and presses the button to complete the packaging automatically. For the fully automatic one, the package is automatically set by simply pressing the button after placing the load on the turntable with a forklift or the like. To complete. In any case, the basic feature is that the wrap film is wound by rotating the turntable.

However, when done manually as described above, it requires a very harsh posture and requires hard work, which tends to cause physical problems such as low back pain. Due to the price, there are many companies that are difficult to introduce.

The present invention is to provide a wrapping apparatus that matches actual needs so that the work can be performed easily and physically easily even if it is not automatic, and the cost of the apparatus can be greatly reduced. Let it be an issue.

Two pillars 3a and 3b are suspended behind a support base 2 having a movable caster 1 at the lower end, and a primary pulley 4A is attached to a lower intermediate portion of the pillars 3a and 3b, and the primary pulley is disposed above the primary pulley 4A. A rope winder 6 with a handle 6h for winding the rope 5 for rotating the pulley 4A is attached, and two rod-like slide columns 7a and 7b are parallel to each other in front of the column bodies 3a and 3b on the support base 2. The slide holes 8a and 8b that are suspended and pass through the slide columns 7a and 7b, the turntable 10 and the wrap film support column 11 on which the roll-shaped wrap film 9 is placed, and the wrap film that suspends further forward A wrap film mounting table 13 provided with a tension bar 12 is supported by the rope 5 so that the slide columns 7a and 7b penetrate and slide through the slide holes 8a and 8b. The group 5 is supported by a secondary pulley 4B provided at an intermediate position between the column bodies 3a and 3b and the slide columns 7a and 7b, and is connected to the primary pulley 4A and the rope winder 6. Thus, the lapping apparatus of the present invention is provided.

As described above, the fundamental difference from the conventional automatic stretch wrapping machine in the present invention is that the conventional one is a turntable on which the loading platform on which the load is placed rotates, and the wrapping force is applied by the rotational force. Whereas the film is wound, the present invention is to place the baggage in an arbitrary place, and conversely move the wrapping device with a movable caster around the baggage to wind it.

That is, the wrap film winding work is performed by human walking. On the other hand, the winding position (height) for the load is selected by moving the rope 5 connected to the rope winder 6 by rotating the handle 6h, and setting the wrap film via the primary pulley 4A and the secondary pulley 4B. This is done by moving the table 13 up and down. The rope 5 includes a chain.

At that time, the slide columns 7a and 7b that are vertically fixed to the support base 2 and the slide holes 8a and 8b provided in the vertically moving wrap film installation base 13 are configured to penetrate and slide with each other. The roll-wrapped wrap film 9 also moves up and down stably while maintaining a vertical state. Note that the wrap film support column 11 is used to maintain the vertical position, and the turntable 10 is a platform on which the lap film support column 11 is placed, but the latter is fundamentally different from a turntable on which conventional luggage is placed.

It is to be noted that the wrap film tension bar 12 is provided so that sufficient tension is applied regardless of the direction when the wrap film setting table 13 is moved to wind the wrap film 9 around the load. This is preferably made of rubbery material and serves to prevent the film from wrinkling or sagging.

Further, if necessary, a disk-shaped fixing weight 14 is placed on the roll-wrapped wrap film 9 so as to be inserted into the head of the wrap-film supporting column 11 in a through hole provided in the center thereof. And the upper and lower sides of the film are prevented from shaking.

Since the slide columns 7a and 7b are supported by the rope 5 so as to pass through and slide through the slide holes 8a and 8b, the wrap film setting table 13 is provided with a backrest 15 such as a chair back. It is made to stand and the lower end of the rope 5 is attached to the upper part. Alternatively, a pipe frame or a lattice may be used instead of the back plate 15. In any case, it is desirable that the wrap film mounting table 13 extending in the horizontal direction perpendicularly to it has a sufficient thickness or a two-layer structure for reinforcement.

According to the present invention, the wrapping operation for preventing the collapse of the load when the cardboard baggage is accommodated and transported in the container or the like is remarkably facilitated without installing a very expensive automatic machine. In other words, since the target baggage is usually 1 to 2 tons in weight, an automatic packaging machine not only requires a high-power motor to place and rotate it, but it is also dangerous if the vertical movement of the stretch film is not automated. Even if it is a company that is expensive and difficult to handle because it requires computerization, the device of the present invention can be easily adopted because it costs about 1 / 10th, and it can carry heavy loads and lift it. On the contrary, it is possible to carry out the work while moving the device that is extremely easy to move and close to the place where the luggage is placed without walking, so there is no painful and difficult middle waist work, causing back pain etc. There is an effect such as no sorrow.

The configuration of the present invention has already been described in detail with reference to the drawings. In practice, based on this, it is possible to design and manufacture the best form arbitrarily according to the actual situation at the site using ordinary materials. For example, the overall shape as shown in the drawing is one of the best modes, but the actual height is preferably about 120 cm, and the dimensions of each part are naturally determined accordingly.

The movable caster 1, the pulleys 4A and 4B, the rope 5, the turntable 10 and the like are all appropriately selected or newly created. In addition, structural materials such as the support base 2, the pillars 3a and 3b, and the slide pillars 7a and 7b are made of a strong metal in principle, and the wrap film installation base 13 is composed of two metal plates or a single sheet with a vertical interval. A thick low specific gravity resin plate is used. In addition, the wrap film tension bar 12 is made of rubber.

According to the test using the prototype, it was confirmed that the wrapping work was very easy, the burden on the body such as posture was drastically reduced, and the work speed was remarkably improved.

The wrapping apparatus of the present invention is highly effective, has high needs, and is easy to manufacture and mass-produce, so that it has sufficient industrial applicability.
