Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a band coil for a packaging machine, and more particularly to the shape of the band coil and its container. Conventionally, the band coil of a so-called fully automatic packing machine which has a band guide arch on the main body of the packing machine, for example,
Width 15 made of plastic, for example, polypropylene, by the means disclosed in Japanese Patent No. 37999.
, about 2500 m of a series of 5 mm strips.
While moving the band end side in the width direction of the paper core, wrap it in multiple layers in the width direction of the paper core to an outer diameter of approximately 400 mm.

Cylindrical shape with width 200+mm and weight approximately 12kg
In order to prevent the band coil from dispersing and unraveling in the width direction during use, both ends are held by disc-shaped circular plates and support rods are used as appropriate to prevent the band coil from unraveling.
It is attached to the end of the main body. 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. Furthermore, in the case of a small so-called desktop packaging machine as shown in Fig. 5, the outer diameter is about 180 mm, the diameter is about 130 mm, the diameter of the paper core is about 70 mm, the length is about 500 m, and the band width is typical. A series of 9 mm band-like bands are wound around the band coil 1, which weighs about 1.3 kg, and is sandwiched between circular plates 2.2 with a diameter of 200 mm, and this is supported on the edge of the main body 4 by support rods 3. has been done.

This tabletop packing machine is widely used for packing relatively small products at the time of sale at stores, etc. Generally, the size of the main body 4 is 200 mm to 300 mm in height, 450 mm in width,
The depth is small, about 350 mm, and when the band coil with the support rod 3 and the circular plate 2°2 is attached to the main body 4, the total width becomes a little less than 800 mm, and the height from the floor when placed on a desk. It is used with a length of about 750 mm. 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 as an original desktop packaging machine, the applicant first made the packaging machine body more compact.As a result of repeated technical improvements, some results were obtained, but the shape of the band coil etc. Since it is standardized by the band manufacturer, band coil 1, sergular play that holds this band coil 1) 2, 2
The part consisting of the support rod 3 that supports the circular plates 2, 2 cannot be miniaturized, and therefore there is no point in making it more compact by attaching it to the compact body. It is impossible to install the band coil, or if it is installed, the overall structure becomes extremely unbalanced, and the band coil sets a limit to the miniaturization of the tabletop packaging machine.

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. It has the disadvantage that it has a tendency to meander, making it impossible for the band feeding mechanism inside the main body to smoothly feed out the band, and if this band coil is attached outside the main body, the overall size cannot be made as compact as expected. .

The inventor aimed to solve the above-mentioned problems by focusing on the fact that tabletop packaging machines pack mostly small items, and the consumption of bands i 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 packing 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.

In order to achieve the above object, the present invention provides a band coil formed by winding a series of band-shaped packing plastic bands in a single layer into a disk shape, and a storage body for storing the band coil. It is characterized in that it consists of an outlet of a band perforated in the storage body.

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 22 cm, matching the area of the bottom surface of the main body, which will be described later, and the weight is approximately 250 g. Reference numeral 11 denotes a storage body which has a volume slightly larger than the entire volume of the coils of the band and whose thickness is slightly thicker than the width of the band, and is formed into a box shape by appropriately folding plastic molding or paperboard.

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 addition, in Figure 1,
A core body 15 is made of plastic or paper and molded into a disk shape like the storage body 11, and the central hollow part of the band coil 10 is fitted into the core body 15 so that there is a margin between the outer diameter of the band coil and the side surface of the storage body. In order to make the rotation of the band coil smoother when pulling out the band when there is too much, storage part 1 is installed.
It is protruding from the center of 1.

Reference numeral 16.16 denotes a guide pin, which is installed near the outlet 13 of the storage section 12 with a gap slightly wider than the thickness of the band. In order to curve the band and to prevent the band from moving unnecessarily in the width direction of the outlet 13 when the band is pulled out, it is provided as necessary together with the core body 15.

As shown in FIG. 3, on the bottom of the packaging machine main body 20, a guide 24 formed of an approximately 11-shaped angle having a gap in which both side edges of the storage body 11 can be freely inserted and removed is attached to the packaging machine main body 20. The bottom surface 22 also serves as a leg part that supports the bottom surface 22.
It is fixed to both side edges of.

FIG. 4 shows the usage state of the band coil 10. The band coil 10 is placed horizontally on the bottom surface of the packaging machine body 20, and the tip of the band pulled out by a desired amount from the outlet 13 of the storage body 11 is attached to the packaging machine body. 20, and is sent out from the top surface 23 of the work table on the packaging machine body 20 via rollers (not shown) that constitute a band feeding and tightening mechanism in the packaging machine body 20.

The present invention is constructed as described above, and its operation will be explained next.

As mentioned above, the end of the band protruding from the outlet 13 of the storage body 11 of the band coil 10 inserted and placed in the guide 24 fixed below the bottom surface 22 of the packaging machine main body 20 (77-) is inserted into the packaging machine. Band insertion slot 2 of main body 20
1, and when the band is fed, Seriton is set as the tightening mechanism, and the forward rotation button is turned on, a predetermined amount of the band is sent out from the work table 23 of the packing machine main body 20 using a timer or the like. 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 will not stay in the center of the storage body 11 and 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 attached to the bottom surface 22 of the packing machine body 2°=8- and pulled out from the guide 24 and replaced with another band coil. Perform a set of

As described above, the present invention provides a band coil formed by winding a series of band-shaped packaging plastic bands in a single layer into a disk shape, a storage body for storing the band coil, and a perforation in the storage body. Since it is constructed from the exit of the band, conventional components for holding the band coil such as circular plates and support rods that support the band coil are eliminated.
Since it is a cassette-shaped 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 compacted to make it portable and convenient. This makes it possible to supply an inexpensive band coil that is easy to replace.

In addition, in the above-mentioned embodiment, the bottom surface 22 of the packaging machine main body 20
Explanation regarding the guide 24 provided at the top The band coil 10 may be placed at any position as long as the band pulled out from the storage body 11 is not twisted near the packing machine main body 20, but it is preferable ( Position the outlet of the storage body in the space formed by the suitably shaped legs that support the main body on the bottom of the main body in the direction of the band insertion opening of the main body so that the disk shape formed by the storage body and the coil inside the storage body is horizontal. Alternatively, the storage body may be formed to a size that allows two coils of the band to be stored horizontally, and the outlet of the band may be placed on both longitudinal sides of the storage body formed in this way. It is also possible to store them in a row.Furthermore, various design changes and usage methods are possible, such as stacking a plurality of storage bodies for storing negative band coils and placing them under the bottom of the main body.

The band coil according to the present invention is not limited to the above-mentioned band coil for a tabletop packaging machine, but can also be applied to a general-purpose automatic packaging machine by winding the band in multiple layers in the width direction of the paper core. The characteristic of the present invention, such as the meandering tendency caused by this, is completely eliminated, and the above-mentioned features of the present invention, such as being convenient to carry, replace, etc., and being inexpensive, can be utilized.
