Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a table-top packaging machine, and more particularly to the shape of a band coil for said table-top packaging machine and means for attaching and using its container.

[Technical background]

Conventionally, the band coil of a so-called fully automatic packing machine having a band guide arch on the main body of a packing machine, for example, has a width of 15.5 mm and is made of plastic, such as polypropylene, by the method disclosed in Japanese Utility Model Publication No. 47-37999. A series of strips formed into a cylindrical shape with an outer diameter of approximately 400 mm and a width of 200 mm by wrapping the band in multiple layers in the width direction of the paper core while moving the band end side in the width direction of the paper core for approximately 2500 m. The band coil weighs approximately 12 kg, and in order to prevent the band coil from dispersing in the width direction and unraveling during use, both ends are held with disc-shaped circular plates and attached to the end of the main body via support rods as appropriate. It is being Also, in so-called semi-automatic packaging machines which do not have a band guide arch, a substantially similar band coil is held at the edge of the main body or below.

[Prior art and problems]

Furthermore, in the case of a small so-called tabletop packaging machine as shown in Figure 5, the outer diameter is approximately 180 mm.
A band coil 1 with a weight of about 1.3 kg is wound with a series of band-shaped bands of 130 mm in width, 70 mm in diameter of the paper core, and about 500 m in length, with a typical band width of 9 mm, and a diameter of 200 mm.
The main body 4 is sandwiched between circular plates 2, 2 and supported by a support rod 3 on the edge of the main body 4. This tabletop packing machine is widely used for packing relatively small products when sold at stores, etc. Generally, the size of the main body 4 is 200 mm to 300 mm in height and width.
It is small at about 450 mm and depth is about 350 mm, and when the band coil with the support rod 3 and circular plates 2, 2 is attached to this main body 4, the total width becomes a little less than 800 mm, and when it is placed on a desk, the width from the floor is small. The height is
It is used with a length of about 750mm. In other words, even a desktop packaging machine is quite large and takes up a lot of space. Therefore, in order to make the packaging machine more compact than the original desktop packaging machine, the applicant first made technical improvements to make the packaging machine body more compact, and as a result, some results were obtained, but the shape of the band coil etc. Because it is standardized by the manufacturer, the parts consisting of the band coil 1, the circular plates 2, 2 that hold the band coil 1, and the support rod 3 that supports the circular plates 2, 2 cannot be miniaturized. By attaching it to the above-mentioned main body which has been made compact, the compactness becomes meaningless, and it is also impossible to attach it to the main body, or if it is attached, the whole becomes extremely unbalanced, and the band coil This marked the limit for miniaturization of tabletop packaging machines. Therefore, in order to downsize the band coil, it is possible to create a band coil in which the band is wound into an elongated cylindrical shape with a small outer diameter, but since the outer diameter is short in this case, the band that is unwound and taken out from the band coil has a tendency to meander. This has the disadvantage that the band cannot be smoothly fed out by the band feeding mechanism inside the main body, and if this band coil is attached outside the main body, the overall size cannot be made as compact as expected.

【the purpose】

The inventor aimed to solve the above-mentioned problems by focusing on the fact that desk-top packaging machines pack mostly small items and the amount of band consumption is naturally extremely small compared to general-purpose fully automatic packaging machines. The present invention has been created, and its purpose is to make the band coil itself extremely compact, mainly to meet the demand for downsizing of the desk-top packaging machine mentioned above, and to make it easy to replace and carry the band coil. At the same time, the purpose is to enable the user to purchase an inexpensive band coil of necessary and sufficient length at any time.

[Composition/effect]

In order to achieve the above-mentioned object, the present invention accommodates a coil of a band formed by winding a series of plastic bands for packaging into a disk shape in a single layer. It is characterized by a storage body having an outlet that can be inserted into and removed from a guide provided on the bottom of the main body.
The storage body is inserted along the guide on the bottom of the main unit, and the tip of the band taken out from the band outlet is guided into the main body. When used, the band coil rotates within the storage body and the diameter of the center expands and is pulled out smoothly. After use, remove the storage container and replace it with a new one.
Insert another storage body into the guide on the bottom of the main body to replace the storage body, that is, the band.

【Example】

DESCRIPTION OF THE PREFERRED EMBODIMENTS The details will be explained below with reference to the drawings showing embodiments of the present invention. In Fig. 1, reference numeral 10 denotes a band coil according to the present invention, which is made by winding a series of belt-shaped polypropylene bands in a single layer in the width direction to form a disc-shaped band coil. The diameter is approximately 22cm according to the area of the bottom of the main unit, which will be described later, and the weight is approximately 250Kg.
It is. Reference numeral 11 denotes a storage body, which has a volume slightly larger than the entire volume of the coil of the band and a thickness slightly thicker than the width of the band, and is formed into a box shape by plastic molding or paperboard appropriately folded. This storage body 11 can also be formed into a bag shape as shown in FIG. Reference numeral 13 is an outlet of the band, and a groove slightly wider than the thickness of the band is cut out to an appropriate length on the side surface 14 of the storage body 11, and the tip end of the band protrudes from the outlet 13 by a length that can be pinched with the fingertips. In FIG. 1, reference numeral 15 denotes a core, which is made of plastic or paper and molded into a disc shape like the storage body 11, and the central hollow part of the band coil 10 is fitted into the core 15, and the outer diameter of the band coil is The band coil is protruded from the center of the storage part 11 in order to make the rotation of the band coil smoother when the band is pulled out, such as when there is too much room between the sides of the storage body. Reference numerals 16 and 16 denote guide pins that are erected near the outlet 13 of the storage section 12 with a gap slightly wider than the thickness of the band.゜To make it curve,
In addition, in order to prevent the band from moving unnecessarily in the width direction of the outlet 13 when the band is pulled out, the core body 1 is
5 and is provided as necessary. As shown in FIG. 3, the bottom surface of the tabletop packing machine main body 20 has a guide 24 formed of an approximately L-shaped angle having a gap in which both side edges of the storage body 11 can be inserted and removed freely. They also function as legs for supporting the packing machine main body 20 and are fixed to both side edges of the bottom surface 22. FIG. 4 shows the usage state of the band coil 10. The band coil 10 is placed horizontally on the bottom surface of the tabletop packing machine main body 20, and the tip of the band pulled out by a desired amount from the outlet 13 of the storage body 11 is placed on the tabletop. The work table top surface 23 on the tabletop packing machine body 20 is inserted into the band insertion opening 21 of the tabletop packing machine body 20, and is inserted into the work table top surface 23 on the tabletop packing machine body 20 via a roller (not shown) that constitutes a band feeding and tightening mechanism in the tabletop packing machine body 20. sent to the outside. The embodiment of the present invention is constructed as described above, and its operation will be explained next. As mentioned above, the bottom surface 2 of the tabletop packing machine main body 20
2. The tip of the band protruding from the outlet 13 of the storage body 11 of the band coil 10 inserted into the guide 24 fixed below is inserted into the tabletop packing machine main body 2.
Insert the band into the band insertion slot 21 of 0, set it in the band feeding and tightening mechanism, and turn on the forward rotation button.
is sent out from the work table 23. At this time, there is moderate friction between the surface on which the coil of the band of the storage body 11 is placed in the storage part 12 and the entire side surface of the coil of the band that is rotated by the band being pulled out, and the inertia due to the pulling out of the band is applied to the coil of the band. This can prevent excess bands from being pulled out from the outlet 13 of the storage body 11. As the band is consumed by packaging, the coil of the band in the storage body 11 expands in the direction of the side surface 14 of the storage body 11 so that the circular space in the center increases in diameter due to the elasticity of the band itself, and the remaining coil remains. The band to be used is storage body 1.
It stays in the center of 1 and does not become difficult to pull out. When the bands are further consumed and all the bands are finally pulled out from the storage body 11, the storage body 11 is pulled out from the guide 24 attached to the bottom surface 22 of the tabletop packing machine main body 20 and replaced with another band coil, and the band is set. I do.

[Other Examples]

In the above embodiment, one band coil was stored in one storage body, but the storage body was formed to a size that could accommodate two band coils horizontally, and the band outlet was formed in this way. It is also possible to provide each on both sides of the storage body in the longitudinal direction. Furthermore, various design changes and usage methods are possible, such as stacking a plurality of storage bodies for storing one band coil and placing them under the bottom surface of the main body.

【effect】

As described above, the present invention accommodates a coil of a band formed by winding a series of plastic bands for packaging into a disk shape in a single layer, is formed slightly thicker than the width of the band, and has a band outlet. Since the storage body containing the band coil can be inserted into and removed from the guide provided on the bottom of the main body, the conventional components for holding the band coil, such as the circular plate and support rod, which support the band coil, are eliminated. Since it is a band coil, it can perfectly meet the demand for compactness by reducing the installation space of the tabletop packaging machine.In addition, the weight and shape of the band coil can be reduced and reduced, making it easy to carry and replace. This makes it possible to provide a tabletop packaging machine that can use inexpensive band coils.
