Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a reel device that supports a band wound in a roll in a packing machine for winding and packing the outer circumference of an object to be packed using a thermoplastic band.

[0002]

[Prior art]

 In a packing machine in which a thermoplastic band is used to fasten an object to be packed and then both ends are welded, the rolled band is pulled out and used, so that the roll band is supported rotatably. A reel device is required.

In a reel device of a conventional packing machine, a shaft for supporting a roll winding band is rotatably attached to a housing of the packing machine by a bearing, and the roll winding band is rotatably supported by this shaft and the band is pulled out. Is possible.

[0004]

[Problems to be solved by the device]

 By the way, it is necessary to make the packing machine as compact as possible in order to reduce the cost during transportation, but when it is externally fixed to the housing as in the conventional reel device, the packing machine is as much as the reel device. However, there is a problem in that the transportation cost will be high because of the bulkiness.

Further, in the conventional reel device, if the roll winding band is rotatably supported by the shaft, the roll winding band rotates due to inertia when the band is pulled out, causing unnecessary slack in the band. There is a problem that an inertia prevention device having a complicated structure must be used in combination.

Therefore, according to the present invention, the mechanism for supporting the roll winding band is disassembled so that the mechanism can be housed in the housing of the packing machine, and the transportation of the packing machine becomes less bulky, and the cost can be reduced. At the same time, it is an object to provide a reel device of a packing machine that can prevent inertia with a simple structure.

[0007]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention provides a support member detachably attached to a lower portion of a packing machine housing supported by detachable legs so as to project downward, and a support member on one side of the support member. A horizontal shaft projecting at a central position, a pair of band support shafts projecting at both upper sides of the shaft on one side of the supporting member and supporting the inner circumference of the roll winding band, and the shaft. A lid member that is detachably fixed to the tip of the roll member, and a resistance member that makes sliding pressure contact with the end surface of the roll winding band is attached to at least one of the facing surfaces of the support member and the lid member, and the support member and the lid member. An elastic body is stretched and arranged at a position on the band pull-out side between them.

[0008]

[Action]

 A support member is attached to the housing of the packing machine, and a pair of band support shafts projecting from the support member support the inner circumference of the roll winding band inserted with respect to the support shaft and the shaft. A roll winding band can be attached by fixing the lid member to the tip, and the roll winding band can be attached by supporting the roll winding band at two points with a pair of support shafts and sliding resistance contact of the resistance member to the end surface of the roll winding band. Prevents inertial rotation of the winding band and eliminates unnecessary slack in the band.

In addition, if the lid member is removed from the shaft and the support member is removed from the housing, and the legs are also removed and housed in the housing, the packing machine can have a housing size. Therefore, it becomes less bulky and the transportation cost can be reduced.

【Example】

 An embodiment of the present invention will be described below with reference to the accompanying drawings.

As shown in the figure, the packing machine supports the lower four corners of the housing 1 with detachable legs 2, and a well-known mechanism that constitutes a main part of the packing machine is housed in the upper part of the housing, and a housing is installed. A reel device 3 is removably attached to the lower part of 1.

The reel device 3 includes a support member 4 fixed to the housing 1 so as to be detachable, and an underwater shaft 5 projecting at a substantially central position on one surface side of the support member 4, as well as the support member 4. A pair of support shafts 6, 6 projectingly provided on both sides of the upper part of the shaft 5 on one surface side, a lid member 7 fixed to the tip end side of the shaft 5 in a detachable manner, and opposing surfaces of the support member 4 and the lid member 7. And a resilient member 9 mounted on the outer peripheral portion between the support member 4 and the lid member 7, and the roll winding band A is supported by the support shafts 6, 6. .

The support member 4 is formed by crossing the strip-shaped metal plates 10 and 10 at a right angle and connecting the outer ends to each other with a ring 11. The upper end extension of both metal plates 10 and 10 is attached to the housing 1. It is detachably fixed to the angle 12 with a screw 13 and is attached in a vertical arrangement so as to project downward from the housing 1.

In order to improve the attachment strength of the support member 4 to the housing 1, the lower end of the reinforcing plate 15 whose upper end is detachably fixed to the housing 1 with the screw 14 has the lower end of the cross portion at the back surface of the strip metal plates 10 and 10. It is fixed to the upper part with screws 15a.

The shaft 5 is fixed on one surface side of the support member 4 so as to be horizontal at the center of the cross portion of the two strip-shaped metal plates 10 and 10. As shown in FIG. Is also a little longer.

The pair of support shafts 6, 6 are horizontally fixed to the strip-shaped metal plates 10, 10 so as to be located on both sides of the upper portion of the shaft 5, and are smaller than the width of the roll winding band A as shown in FIG. It's a short length.

The support shafts 6 and 6 are formed by bending a single metal wire into a planar U-shape and fixing the ends of the parallel parts on both sides to the strip-shaped metal plates 10 and 10 by welding them together. A cylindrical shaft 16 that rotatably supports the roll winding band A is externally fitted on the shafts 6, 6.

The roll winding band A has a cylindrical shape in which the band a is wound around the outer circumference of the paper tube B, and the upper two places are supported by the support shafts 6 and 6 on the inner circumference of the paper tube B. The shaft 5 and the shaft 5 are arranged substantially coaxially.

The lid member 7 is formed by crossing the strip-shaped metal plates 17, 17 at a right angle and connecting the outer ends with a ring 18, and a boss 19 provided at the center of the cross portion is fitted to the tip of the shaft 5. It is fitted and inserted, and the screw 20 is tightened to be detachably fixed to the shaft 5.

The resistance member 8 attached to the opposing surfaces of the support member 4 and the lid member 7 is made up of a combination of an elastic body 21 such as rubber or sponge and a sliding plate 22, and each strip-shaped metal plate 10, 10 and 17 is formed. , 17 attached to the support shafts 6 and 6, the lid member 7 is compressed with the elastic member 21 so that the sliding plates 22 are in pressure contact with both end surfaces of the roll winding band A fitted to the support shafts 6, 6. Fixed to.

Between the ring 11 of the support member 4 and the ring 18 of the lid member 7, a pair of elastic bodies 9 and 9 sandwiching the band a are stretched at a position where the band a is pulled out from the roll winding band A. There is.

In the illustrated case, elastic bodies 9 and 9 are coil springs, one end of which is fixed to the ring 11 of the support member 4 and the other end of which is detached from the ring 18 of the lid member 7. The band a is free to be pulled out to the packing machine side by sandwiching the band a in a parallel state in which they are in contact with each other, and when the band a is pulled back, the band a is supported and drooped down. It serves to reduce the amount generated. The elastic bodies 9, 9 may be attached to the lower part of the housing 1 and arranged.

The reel device of the present invention has the above-described structure, and the reel device 3 must set the roll winding band A on the lower part of the packing device housing 1 supported by the legs 2 before the housing 1 is set. The support member 4 is fixed with screws 13 and is reinforced with the reinforcing plate 15, and the roll winding band A is externally fitted to both the support shafts 6 and 6 and the shaft 5, and the support band 4 is attached to the support shaft 6. , 6, support.

Next, the lid member 7 is inserted into the tip of the shaft 5, positioned so that the strip-shaped metal plates 17 and 17 face the strip-shaped metal plates 10 and 10 of the support member 4, and the cover member 7 is pushed in. Then, the elastic members 21 on both sides are compressed, and the lid member 7 is fixed to the shaft 5 so that the roll winding band A is sandwiched between the sliding plates 22 on both sides.

The band a drawn from the roll winding band A is drawn into the housing 1 of the packing machine through the space between the elastic members 9 stretched between the support member 4 and the lid member 7.

During the band drawing process of the packing machine, as indicated by the solid line in FIG. 2, the band a is drawn in a tensioned state, and the roll winding band A rotates counterclockwise in FIG.

Since the sliding plates 22 are pressed against both end surfaces of the roll winding band A, resistance to rotation is generated, and further, the support shafts 6 support the upper two portions of the inner circumference of the paper tube B. Since the part is used as the fulcrum of rotation, the smoothness of the rotation is lacking, and when the pulling out of the band a is stopped, the roll winding band A quickly stops without inertial rotation, which causes an extra It is possible to prevent the band from being sent out and causing the band to droop. Due to the elasticity of the elastic body 21, the resistance member 8 follows changes in both end faces when the roll winding band A rotates, and constantly exerts a braking effect.

Further, during the band tightening process of the packing machine, the pulled back band a is returned to the lower part of the housing 1. However, as shown by the alternate long and short dash line in FIG. Since it is held by the elastic members 9 and 9, the amount of drooping of the retracted band can be reduced in the lower portion of the housing 1.

Further, during transportation of the packing machine, the lid member 7 is removed from the shaft 5, the support member 4 and the reinforcing plate 15 are removed from the housing 1, and these are stored together with the legs 2 in the space inside the housing 1. If this is the case, the overall volume will be low, and transportation costs can be reduced.

[0030]

[Effect of device]

 As described above, according to the present invention, since the configuration is as described above, the components can be disassembled and housed in the housing, the packing machine can be made bulky, and the transportation cost can be reduced.

In addition, since the roll winding band is supported at two places and is sandwiched by the resistance members from both sides, the inertial rotation of the roll winding band is prevented when the band is pulled out, and the band is not pulled out unnecessarily. You can

Furthermore, since the pulled-out portion of the band is supported by the elastic body stretched between the support member and the lid member, it is possible to reduce the occurrence of drooping of the pulled-back band.

Further, since the roll winding band is sandwiched from both sides by fixing the lid member to the shaft, even if there is an error in the width of the roll winding band, by selecting the fixing position of the lid member, Resistance can be imparted to the roll band.
