The present invention relates to a variable drive device of a packaging box disc cutting equipment and a cutting method using the same, and more particularly employs a plurality of gear combinations that can vary the speed of the drive shaft while being engaged with the drive shaft of the cutting equipment, By applying the method of cutting by adjusting the rotation period of the cutter according to the cutting width of the original packing box by varying the rotational speed of the drive shaft, it is possible to extinguish several packing box originals having various widths with one facility. Therefore, the overall workability and productivity can be improved, and a variable driving device of a packaging box disc cutting facility capable of operating a small scale of equipment even when handling a large packaging box disc and a cutting method using the same.

In general, various types of packaging means are used to prevent damage and damage in the distribution of goods.Because of the advantages of light weight and easy handling, packaging boxes made of hexahedron by bending corrugated flat plate Is used a lot.

Such packaging box is a process of supplying a predetermined amount of original packaging box discs one by one, printing predetermined text on the packaging box disc, cutting at least six bent portions of the packaging box disc to be bent into a cube. It is produced in the form of a complete packaging box through the process of bending, the process of bending in the form of a cube actually used.

For example, the manufacturing process of the packaging box is mostly made of a generalized automated process, and at the initial stage of the process, a printing operation is performed on the original packaging box which is supplied at the same time as the original packaging box original. At the end of the process, one box is completed by bending and cutting between the wings of the disc of the box for the final product.

The present invention is the object of the drafting equipment for cutting the original packaging box of the packaging box manufacturing process as described above.

Usually, the packing box disc cutting equipment includes a cutter for cutting, a plurality of cutter fixing drums, a drive shaft for mounting and rotating the drum, a driving device that provides power to the drive shaft, and a roller that supports the lower side during the transfer and cutting of the packing box disc. When the original packaging box passes through the upper drum and the cutter and the lower roller, the cutting box for bending is made in the original packaging box disc by the cutters of the continuously rotating drum.

However, in the case of the original packaging box cutting equipment, the cutting width of the cutting box is adjusted according to the cutting width of the packaging box by adjusting the mounting width of the cutter within the range of the diameter of the drum for fixing the cutter, that is, within the circumference of the drum. There is a drawback that the size of the original packaging box that can be processed is limited.

For example, if the cutting width of the original box of the packing box is about 1500mm or less, the cutting operation can be performed while adjusting the mounting width of the cutter. There is a disadvantage in that the overall size of the equipment is increased, such as the (diameter) to be larger, and the workability and productivity are greatly reduced because it requires a lot of labor and time for the replacement of the entire cutting unit.

Accordingly, the present invention has been made in view of the above, and is provided with a deceleration means composed of a plurality of gear combinations, it is possible to vary the speed of the drive shaft while being engaged with the drive shaft of the cutting equipment, the original packaging box The speed of the drive shaft, that is, the rotation period of the cutter, can be controlled according to the cutting width of the cutter. Thus, the cutting operation can be easily performed even for the packaging box discs having various specifications (cutting widths), especially for large packaging box discs. Therefore, it is possible to improve the overall workability and productivity related to the manufacture of the packing box, and even one small facility can handle not only the small box original but also the large box original, and thus the operation of the facility can be improved. Variable drive device for packaging box disc cutting equipment that can be used more efficiently There is provided a cutting method.

The present invention for achieving the above object is a packaging box disc cutting equipment, consisting of a plurality of gear combinations are driven in the direction opposite to the rotation direction of the cutting shaft drive shaft by varying the rotational speed of the drive shaft to the cutting width of the packaging box disc Accordingly, it characterized in that it comprises a deceleration unit to enable the rotation period of the cutter.

In addition, the reduction unit is mounted to the cutting shaft drive shaft in the idle structure and the main gear receives power from the drive unit and the sub-gear integrally assembled with the main gear, and the drive shaft while being arranged side by side adjacent to one side of the sub-gear A drive gear which is integrally mounted on the drive shaft to rotate the drive shaft, and is disposed side by side of the drive gear, and is mounted in an idle structure on the drive shaft and rotatable in a direction opposite to the drive shaft, A two-stage gear type electric gear that is mounted in an idle structure on a horizontally extending pin on one side and transmits the power of the sub-gear side to the driving gear side while being engaged with the sub-gear and the driving gear at the same time, and meshed with one side of the reduction gear Reduction gear for rotating the reduction gear and reduction gear for operation of the reduction gear Characterized in that comprises a.

In addition, the subgear and the drive gear is characterized in that it has a different number of teeth.

In addition, the deceleration drive unit is characterized in that the drive is intermittently driven in response to a signal from the control unit is programmed the rotational speed of the drive shaft corresponding to the cutting width of the packaging box disc.

On the other hand, the present invention for the above purpose is to reduce the rotational speed of the drive shaft in accordance with the standard (cutting width) of the packaging box disc in a way to vary the rotational speed of the drive shaft of the cutting equipment using a reduction gear means consisting of a plurality of gear combinations. It is characterized by performing a cutting operation by setting.

In addition, the method of varying the rotational speed of the drive shaft is characterized in that the reduction gear means is rotated in the opposite direction to the rotational direction of the drive shaft to absorb some of the rotational force provided to the drive shaft.

In addition, the reduction gear means is characterized in that it can slow the rotational speed of the drive shaft while rotating intermittently with respect to the continuously rotating drive shaft.

In the present invention, if necessary through the organic gear transmission between the drive shaft of the packaging box disc cutting equipment and the reduction unit consisting of a plurality of gear combinations, for example, the rotation speed of the drive shaft when the specification (cutting width) of the packaging box disc is changed Cutting may be performed in a manner to properly control the.

For example, if a cutting box disc with a cutting width of 1500mm or more needs to be cut, the rotation speed of the drive shaft is set to be slow to slow down the cutter's one rotation cycle, that is, the cutter rotates one round after the first cutting operation. By delaying the time required to perform the cutting operation can be performed according to the cutting width of the original packaging box, and thus can actively respond to the increase in the size of the original packaging box.

This change in the rotational speed of the drive shaft is possible through the deceleration action of the reduction unit, i.e. rotation in the appropriate opposite direction.

In other words, the rotational speed of the drive shaft may be varied in such a manner that the reduction unit is rotated in the opposite direction with respect to the rotational direction of the drive shaft to absorb a part of the rotational force transmitted to the drive shaft.

At this time, the rotation speed of the drive shaft can be variously controlled by adjusting the time for operating the reduction unit.

In other words, when the cutting width of the original packaging box is very large, the rotation speed of the drive shaft can be lowered by increasing the operating time of the reduction unit.

The operation time of the deceleration unit can be controlled by a controller that controls the rotation of the drive shaft.

For example, when the size of the packaging work disc is determined, that is, the length between the primary cutting part and the secondary cutting part is determined, the control unit sets the operating time of the reduction unit based on the rotation speed of the drive shaft that is already set. Then, the deceleration unit can be controlled by outputting a control signal to the deceleration unit side during the set time at this time.

The method of setting the operating time of the deceleration unit by calculating the specifications of the original box of the packaging box and the rotational speed of the drive shaft, and the method of operating the deceleration unit through the output control of the controller are particularly limited as long as they are commonly known in the art. Can be adopted.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a cross-sectional view showing a variable drive device of the packaging box disc cutting equipment according to the present invention.

As shown in FIG. 1, the drive shaft 10 of the cutting facility is installed in both ends of the support structure rotatable while passing through the bearing housing 20 installed on the frame 110 of the cutting facility.

Only one support portion of the drive shaft 10 is shown here.

The deceleration unit 100 which decelerates the rotation of the drive shaft 10 has an operation characteristic of being driven in a direction opposite to the rotational direction of the drive shaft 10 while being combined in a gear transmission structure on the drive shaft 10.

On one side of the drive shaft 10 is a power gear 120 that is operated by the operation of a drive (not shown) is disposed, from which the drive shaft 10 can be rotated by receiving the initial power.

The main gear 11 receiving initial power from the power gear 120 is disposed on the outside (left side of the drawing) based on the frame 110, and the main gear 11 at this time is driven by a bearing shaft ( 10) is mounted on the structure rotatably supported while being supported on.

The sub-gear 12, which is combined with the main gear 11 in a pair, is also mounted on the drive shaft 10 via a bearing to be freely rotatable, and is in close contact with the main gear 11 in a concentric manner. Is assembled integrally through bolting and the like.

The main gear 11 and the sub gear 12 are portions that receive power from the driving unit, and do not directly drive the driving shaft 10.

One side of the sub-gear 12, the drive gear 13 is arranged at a close distance, the drive gear 13 is mounted on the drive shaft 10 while the locking member 21, such as a key, power lock, etc. By integrally assembled with the drive shaft 10 serves to directly rotate the drive shaft (10).

That is, the main gear 11, the sub gear 12, and the drive gear 13 are arranged side by side on the drive shaft 10 to receive power and rotate the drive shaft 10.

The transmission relationship between these gears is described in detail later.

Here, the subgear 12 and the drive gear 13 have different number of teeth, for example, subgear: drive gear = about 22:20. Accordingly, the sub-gear 12 and the drive gear 13 are rotated in the same manner as being connected to the electric gear 16 having a pair of teeth, which will be described later, but the rotational ratio is different depending on the difference in the number of teeth.

The reduction gear 14, which performs the deceleration function substantially in the reduction unit 100, is mounted to the distal end of the drive shaft 10, and is assembled in a structure rotatable freely with respect to the shaft by interposing a bearing with the shaft. .

The reduction gear 14 is composed of a large gear having a larger diameter than the gears. Accordingly, the reduction gear 14 is reduced as much as possible after reducing the power (rotational speed) provided from the reduction driving unit 18 to be described later. You will be able to perform the function.

Power transmission between the main gear 11 and the sub gear 12 and the drive gear 13 is made by the electric gear 16.

The electric gear 16 has a two-stage gear shape for simultaneously engaging the sub-gear 12 and the drive gear 13, and is horizontally (vertically to the surface) at one side edge portion of the reduction gear 14. It is mounted in an idle structure on the extending pin 15.

At this time, each end of the electric gear 16 has the same number of teeth of the corresponding gear to be engaged respectively. That is, one end is engaged with the subgear 12 and the driving gear 13, respectively.

The electric gear 16 mounted as described above is engaged with the sub gear 12 and the driving gear 13 at the same time, and serves to transfer the power of the sub gear 12 side to the driving gear 13 side.

In addition, as the reduction gear 14 rotates, the sub-gear 12 and the driving gear 13 are driven along the tooth surface (as in the idle driving mode), and also partially absorb the rotational force transmitted between the gears. do. That is, when the reduction gear 14 operates, the power transmission of the electric gear 16 is transmitted to the sub gear 12 and the drive gear 13, respectively, and rotates in the same manner, but the rotation of the drive gear 13 according to the number of teeth. It will slow down.

The deceleration driving unit 18 for driving the reduction gear 14 is installed in a structure arranged side by side on one side of the drive shaft (10).

The deceleration drive unit 18 is a deceleration drive that provides power to a deceleration drive gear 17, a deceleration drive shaft 19 for returning a deceleration drive gear 17, and a deceleration drive shaft 19 to be engaged with the deceleration gear 14. It consists of a motor (not shown) and the like, the deceleration drive shaft 19 is supported in a rotatable structure on the frame 110 is arranged in parallel with the drive shaft 10, the end of the deceleration drive gear 17 is mounted. .

When the deceleration drive unit 18 is operated by the control signal of the control unit, that is, when the deceleration drive shaft 19 is rotated by the operation of the supplied deceleration drive motor, the deceleration drive gear 17 rotates the deceleration gear 14. At this time, the rotation of the reduction shaft 14 causes the electric gear 16 not to be in place and rides on the toothed surfaces of the sub-gear 12 and the drive gear 13, and the rotational direction of the drive shaft 10 As it proceeds in the opposite direction, the rotation speed of the drive gear 13 and the drive shaft 10 connected thereto having fewer teeth than the sub gear 12 is slowed down.

Therefore, the power supplied from the power gear 120 at the drive side is transmitted through the transmission path of the main gear 11 → sub gear 12 → electric gear 16 → drive gear 13 → drive shaft 10, Subsequently, the cutter rotates at regular intervals by the rotation of the drive shaft 10, and the cutting operation can be performed, and the power of the deceleration drive unit 18 is reduced in the deceleration drive shaft 19 → deceleration drive gear 17 → deceleration gear 14 It is transmitted through the transmission path of the) to the idle movement of the electric gear 16 can be reduced rotation of the drive shaft (10).

Referring to the operating state of the variable drive device according to the invention configured as described above are as follows.

2 and 3 are perspective views showing a primary cutting operation state and a secondary cutting operation state of the packaging box disc cutting equipment according to the present invention.

As shown in FIG. 2, when the original packaging box is moved in the width direction by the conveyor means and positioned in the cutting work area, the primary cutting of the original packaging box is performed by a cutter on the drive shaft 10.

Of course, the drive shaft 10 at this time is in a state of continuously rotating.

As shown in FIG. 3, after the first cutting, the original packaging box is continued, and the driving shaft 10 at this time is also continuously rotating.

At this time, while the deceleration drive unit 18 is operated by the output control of the control unit, the reduction gear 14 rotates in the opposite direction to the rotational direction of the drive shaft 10, and together with the drive gear 14 and the subgear 12. ), The electric gear 16 engaged with the gear moves along a tooth surface of these gears and moves at a constant trajectory. After the predetermined trajectory is performed, the electric gear 16 is stopped at the position by power cutoff of the reduction gear.

Of course, in addition to the intermittent progression of the electric gear 16 as described above, if appropriately adjusted in consideration of the rotational speed of the reduction gear 14 and the rotational speed of the drive shaft 10, the movement state of the electric gear 16 is always in the progression mode. If the standard (cutting width) of the original packaging box is increased, the movement trajectory of the electric gear may be set longer in the case of advancing intermittently, and the movement speed of the electric gear in the case of the continuous progress. (Speed of reduction gear) can be set faster.

Thus, the power transmitted between the sub-gear 12 and the drive gear 13 while the electric gear 16 is moved is reduced by the movement of the electric gear 16, that is, as long as the electric gear 16 is moved As the power transmitted from the gear to the sub gear is lost by the gear tooth difference engaged with the electric gear, the rotation speed of the drive shaft 10 is slowed.

The rotation speed of the drive shaft 10, that is, the rotation period of the cutter, is set in consideration of the above-mentioned deceleration action according to the specifications of the packaging box original handled for cutting, so that the traveling speed of the packaging box original and the rotation period of the cutter The second cutting part of the original box of the packaging box can be accurately cut by the first rotation operation of the cutter after the first cutting while falling.

Therefore, since the rotational speed of the drive shaft can be appropriately set in accordance with the specifications of the corresponding packing box disc in a manner of controlling the above-mentioned reduction unit, the cutting process of the packing box disc of various specifications is possible.

As described above, the present invention performs cutting while adjusting the speed of the drive shaft in accordance with the standard (cutting width) of the means and a box capable of varying the speed of the drive shaft while being engaged with the drive shaft of the cutting equipment. By providing a way to do this, it is possible to handle all the packing box discs of various specifications, from the small packing box originals to the large packing box originals, so that the overall workability and productivity of the packing box manufacturing can be improved. In addition, as a small facility can be handled in a variety of small box packaging disc as well as a large packaging box original, there is an effect that can operate the equipment more efficiently.
