The present invention relates to a band packaging machine, and more particularly to a band packaging machine for automatically binding the various packages to the band.

Typically, a band packaging machine that binds various packages in bands is used in a number of models are conceived.

Such a band packer is provided with a band guider for guiding the band along the outer surface of the package inside the machine of the band packer in order to bind the package to the inside of the machine to bind the band.

However, in the case of a band packaging machine that is commonly used, because the band guider is provided in a fixed type, it is possible to bind only a package of a certain size to the band.

Therefore, if the size of the package to be bound by the band is changed, there is a inconvenience to have a number of band packing machines suitable for the size of such a package.

On the other hand, in order to solve this problem, a band guider is provided in a large size, and a method of banding a small package as well as a large package that meets the specifications of the band guider through a large band guider may be considered. If there are many differences in the shape of the band guider, since the distance between the band guide and the package formed in the band guider is generated, there is a problem that it is difficult to smoothly bond the band, such as twisting the band when the band is bound.

The present invention has been made in view of the problems of the prior art to provide a band-size band band packing machine that can be banded to a package of various sizes in one band packer by moving the band guider according to the size of the package.

In order to solve the above problems, the present invention,

In order to automatically bind various packages to a band, a band guider having at least three sides to form a packing space in which the package is located, and a band guide path through which the band is supplied together with the band guider, are formed on the package. A band packing machine comprising a plurality of band guide flaps provided along the band guider to open the band guide path when the band guide path is opened, wherein the band guiders constituting at least one side of the band guiders are adjacent to each other. A movable band guider is provided to be slidable with respect to adjacent band guiders on both sides, and the movable band guider is connected to the movable band guider to move the movable band guider so that the movable band guider is slidable along the adjacent band guider. Including means Made, characterized in that one according to the size of the packages to move said movable band guider so as to adjust the size of said packaging space.

In general, the band guider may refer to a band guider having a “Π” shape except for the band guider provided in the band packer. However, in this specification, the band guider may include a packing space in which the package is located in the band packer in order to bend the package. On the basis of the fact that it is formed was described as consisting of at least three band guiders. Therefore, the band guider formed on the band packer body itself to form a band guide path may also be understood as a band guider constituting one side. In addition, the band guider as a whole does not necessarily form a sealed rectangle, and most band packing machines have a form in which a part of one side is open for transmission and binding of the band. In addition, although the movable band guider is described as constituting the side, this description does not mean that the movable band guider is formed in a straight line, and in some cases, the movable band guider is formed in an arcuate shape.

It is sufficient that the movable band guider driving means is connected to the movable band guider to move the movable band guider, and various methods are known as such driving means. That is, as the simplest means, it can be assumed that the mobile band guider applies linear force directly to the mobile band guider, taking into consideration that the linear band guider performs a linear motion. A configuration in which possible pistons are connected to the movable band guider can be considered. As a more complicated means, a motor for rotating motion, a converter connected to the motor to convert the rotational motion into a linear motion, a movable band guider connected to the converter, and the like can be considered.

In the above, both ends of the movable band guider

A corner band guider may be provided along the adjacent band guider so as to protrude toward the pavement space part so that a longitudinal section thereof forms an acute angle with the adjacent band guider. More preferably, the corner band guider has an arcuate cross section. It is desirable to achieve. The shape of this corner band guider has advantages in two respects. The first is that the band past the adjacent band guider can be smoothly transported along the corner band guider. The second is that the corner band guider is provided to the adjacent band guider as the corner band guider moves along the adjacent band guider. The band guide flaps collide with each other, and the band guide flaps may be smoothly opened and closed according to the introduction of the corner band guiders forming an acute angle with the adjacent band guiders.

The flap opening and closing portion of the corner band guider protrudes along the adjacent band guider to the opposite side of the pavement space portion so that a longitudinal section thereof forms an acute angle with the adjacent band guider (more preferably to form a concave arcuate shape). It is preferable to add. The flap opening and closing part is the corner band guider is moved along the adjacent band guider as the corner band guider collides with the band guide flap provided in the adjacent band guider, during this collision, the band guide flap is acute with the adjacent band guider. In order to be able to open and close smoothly according to the introduction of the flap opening and closing part. The flap opening and closing portion may not only be made by processing the shape of the plate, but also may be considered to form a triangle shape using a steel wire, and then attach it to the corner band guider to form an acute angle with the adjacent band guide.

In the above description, the corner band guider is divided into a band pull-in corner band guider and a band emitting corner band guider according to a band supply direction, and the band pull-in corner band guider faces the adjacent band guider. The movable coupling part consisting of a movable rail part and a movable rail groove part is formed along the longitudinal direction of the adjacent band guider, and the adjacent band guider is composed of a stationary rail groove part and a stationary rail part along the length direction on a surface facing the packing space part. It is preferable that the stationary coupling portion is formed corresponding to the movable coupling portion, and the band retractable corner portion band guider can move while forming rail coupling along the adjacent band guider. The rail coupling acts to constrain the movable band guider to linear movement.

In the above, the movable rail portion of the band lead-in corner band guider extends toward the paving space portion along the stationary rail groove portion, protrudes toward the paving space portion while forming an acute angle with the stationary rail portion, and is supplied to the band. Is preferably formed to prevent the hook from being caught in the movable rail groove.

In the above, the width of the movable rail groove portion is preferably narrower than the width of the band to be supplied. This is because if the width of the movable rail groove portion is wider than the width of the supplied band, the supplied band may directly collide with the movable rail groove portion without meeting the stopping prevention portion.

Hereinafter will be described in detail the configuration and operation according to an embodiment of the present invention.

1 is a front view of an embodiment according to the present invention, Figure 2 is a view showing the configuration of the band guide path in particular among the A-A cross section of FIG.

Referring to Figure 1 will be briefly described the configuration of the band packaging machine.

The package is transferred to the package space 50 through a conveyor 10 such as a belt conveyor or a roller conveyor, and the package is drawn to a position for bending.

When the package is located in the package space 50, the band is supplied from the packaging machine main body 20 and the band is wound after the band is wound around the outer surface of the package along the band guide path 70 formed by the band guider. The packaging operation is completed. The configuration of such a band packer is already known in a variety of ways, so a detailed description thereof will be omitted.

The band guider located above the band guider is a movable band guider (100, 200, 300).

The movable band guiders 100, 200 and 300 may move along adjacent band guiders 400 and 500, and a geared motor 40 is provided as a driving source for the movement of the movable band guiders 100, 200 and 300. Due to the rotational force of the 40, the feed screw 41 provided along the longitudinal direction of the adjacent band guiders 400, 500 is rotated on the side of the adjacent band guiders 400, 500 through a chain or the like, and the chair of the feed screw 41 is rotated. The power causes vertical movement, that is, linear movement, of the rotational force converter 42 fixed to the movable band guiders 100, 200, and 300. The rotational force converting unit 42 is coupled to the thread of the feed screw 41 to perform linear movement in accordance with the rotation of the thread of the feed screw 41. As such a means for converting the rotational motion into a linear motion is known a wide variety of means, embodiments of the present invention is only one example, it is not limited thereto.

Therefore, the movable band guiders 100, 200, and 300 coupled thereto are moved up and down according to the vertical movement of the rotation force converting unit 42. 1 is a dotted line when the mobile band guiders (100, 200, 300) is located at the lowest point, and the solid band when the position is located at the highest point.

The movable band guiders 100, 200, and 300 of the present embodiment are corner bands connected to both ends of the central movable band guider 100 and the central movable band guider 100 so as to be movable along the adjacent band guiders 400 and 500. Consists of guiders (200, 300), the corner band guiders (200, 300) is configured to slide along the adjacent band guiders (400, 500).

The corner band guider may be divided into a band retractable corner band guider 200 and a band emitting corner band guider 300 according to a band supply direction.

In the present embodiment, the band is supplied from the lower part of the packaging machine main body 20 and moved along the band guider 400, 200, 100, 200, 500 in a clockwise direction and then introduced into the upper packaging machine main body 20. It is assumed. Accordingly, the band retractable corner band guider 200 has a band introduced in a relationship with the adjacent band guider 400, and the band emitting corner band guider 300 has a band emitted in a relationship with the adjacent band guider 500. will be.

2 is a view for showing the configuration of the band guide path of the cross section AA of Figure 1, the band guide path 70 refers to the space where the band 80 is fed, in the present embodiment the stationary coupling portion 410, both The band guide path 70 is formed through the guide wall 71 constituting the side wall and the band guide flap 72.

The stationary coupling part 410 constituting the lower portion of the band guide path 70 (refer to FIG. 2) has a unique shape as the shape of the band pull-in corner band guider 200, which will be described later, to be rail-coupled, but in another part. This shape does not necessarily have to be maintained. That is, the portion where the sliding of the band lead-in corner band guider 200 does not occur may be modified in various forms.

The guide wall 71 serves to prevent the band 80 is separated from the side of the band guide path 70, the band guide flap 72 is elastically supported by the spring 73 to the band guide Close the top of 70.

The band guide flap 72 is opened when the band is bound, and is closed again by the elastic force of the spring 73 when the band leaves the band guide path 70 for the band. Such a configuration can be variously modified as a known technique.

3 is a perspective view illustrating a state before coupling the corner band guider and the adjacent band guider of FIG. 1, and FIG. 4 is a view of the band-input corner band guider and the adjacent band guider with the flap opening and closing portion 220 of FIG. 3 removed. Figure 5 is a perspective view showing a state before coupling, Figure 5 is a view of the band guide-in corner band guider of Figure 4 from the bottom, Figure 6 is a view showing the band is supplied along the band guide-in corner band guider of Figure 5 Conceptual diagram.

A band retractable corner band guider 200 among corner band guiders will be described.

The band retractable corner band guider 200 is formed to protrude toward the pavement space 40 along the adjacent band guider 400 and its longitudinal section forms an acute angle with the adjacent band guider 400. To achieve. The band guider 200 has a shape in which a plurality of bands are formed along the adjacent band guider 400 and a point for easily feeding the band from the adjacent band guider 400 to the band retractable corner band guider 200. The guide flap 72 is to prevent the sliding of the band guide-type corner band guider 200. That is, when the band guider 200 moves forward, the band guide flaps 72 provided at the front end of the band guider 200 form an acute angle gradually in turn, and when the band guider 200 passes, the band guide 200 passes. The flap 72 is closed by the elastic force of the spring 73.

In addition, the band retractable corner band guider 200 also protrudes along the adjacent band guider 400 to the opposite side of the packing space 40 so that its longitudinal section forms an acute angle with the adjacent band guider 400. More preferably, an arcuate flap opening and closing portion 220 is provided. The flap opening and closing part 220 prevents the band guide flap 72 from interfering with the reverse of the band retractable corner band guider 200.

Meanwhile, the band lead-in corner band guider 200 has a movable coupling part 210 formed on a surface in contact with the adjacent band guider 400.

The movable coupling part 210 is formed by alternating the movable rail part 211 and the movable rail groove part 212 along the longitudinal direction of the adjacent band guider 400, and the movable coupling part 210 is the adjacent band guider 400. The rail is engaged with the stationary coupling portion 410 of the.

On the other hand, the adjacent band guide 400 adjacent to the band pull-in corner band guider 200, the stationary coupling portion 410 is formed on the surface facing the band pull-in corner band guider 200. The word stationary above and below means that the engagement surface of the adjacent band guider remains relatively stationary with respect to the movement of the movable band guider.

The stationary coupling part 410 is composed of a stationary rail groove part 411 and a stationary rail part 412 corresponding to the movable coupling part 210. Therefore, the movable rail part 211 is moved to the stationary rail groove part 411. The rail groove portions 212 are rail-coupled to the stationary rail portions 412, respectively.

On the other hand, when the band 80 directly meets the movable rail groove part 212, when the band 80 is viewed based on the band 80, the band 80 moves along the stationary rail part 412 and is higher than the stationary rail part 412. Meet the movable rail groove portion 212 in the position, in this case the band 80 is not smoothly supplied as shown in Figure 6 along the band guider 200, the band 80 is formed below the movable rail groove portion 212 It may be a case where the gap is entered or caught by the front end of the movable rail groove 212. That is, due to the structural relationship of the rail coupling, from the standpoint of the band 80, the height of the movable rail groove portion 212 inevitably be higher than the stationary rail portion 412, so that the meeting with the movable rail groove portion 212 Should be avoided.

In order to solve this problem, in the present embodiment, the movable rail part 211 extends along the stationary rail groove part 411 to the pavement space part 50 side (the lower part in the present embodiment), and the stationary rail part ( 412 to form an acute angle preventing protrusion 211a protruding toward the packaging space 50 side (in the case of this embodiment, the right side).

In addition, the width of the movable rail groove 212 is to be narrower than the width of the band 80 is supplied. This is when the width of the movable rail groove portion 212 is wider than the width of the band 80 is supplied when the band 80 meets the movable rail groove portion 212 through the space between the stopper (211a) With that in mind.

Therefore, according to the present embodiment, the band 80 does not meet the movable rail groove 212 in any case, and necessarily meets the locking prevention portion 211a first, so that it can be smoothly supplied as shown in FIG. 6.

FIG. 7 is a perspective view illustrating a state in which the band emitting corner band guider and the adjacent band guider are coupled before the flap opening and closing unit 320 of FIG. 3 is removed, and FIG. 8 is a lower portion of the band emitting corner band guider of FIG. 7. 9 is a conceptual view showing a state in which the band is supplied along the band-emitting corner band guider of FIG. 8.

The band emitting corner band guider 300 will be described among the corner band guiders.

The flap opening and closing portion 320 of the band emitting corner band guider 300 plays the same role as the flap opening and closing portion 220 of the band retractable corner band guider 200.

Meanwhile, the band emitting corner band guider 300 also includes a movable rail part 311 and a movable rail groove part 312 as the movable coupling part 310, and the adjacent band guider 500 has a stationary coupling part 510. ) To form a stationary rail groove portion 511 and the stationary rail portion 512 to form a rail coupling with each other.

However, the sliding coupling of the band emitting corner band guider 300 and the adjacent band guider 500 is not necessarily a rail coupling of the present embodiment, and much more various combinations than the band retractable corner band guider 300. I think this is possible.

That is, the band 80 supplied as shown in FIG. 9 meets the adjacent band guider 500 after passing the band emitting corner band guider 300, but in this supplying process, if there is no special reason (the position of the band 80). Since the height of the stationary rail portion 512 of the adjacent band guider 500 is always lower than the height of the movable rail groove portion 312 of the band emitting corner band guider 300, it is possible to supply a smooth band without a special structure. do.

Parts not specifically mentioned for other parts related to the band emitting corner band guider can be regarded as the same as those described in the band retractable corner band guider.

FIG. 10 is a perspective view illustrating a state after coupling of a corner band guider and an adjacent band guider of FIG. 1.

On the other hand, the present band packer is generally considered to be used in two modes.

If the size of the package to be wrapped is changed over a period of time, the machine itself can be operated by moving the movable band guider to a certain height.

However, if the size of the package to be band-wrapped changes more than once a day, the measuring means for measuring the size of the package is placed on the conveyor section so that the measuring means transmits the information on the measured size of the package to the band packing machine. The movable band guide can be automatically moved to an appropriate height according to the information about the size of the package.

The above embodiment is only a preferred embodiment of the present invention, the technical idea of the present invention can be variously modified or adjusted by those skilled in the art, if such adjustment or modification uses the technical idea of the present invention it is the scope of the present invention It belongs to.

According to the present invention, it is possible to provide a band size variable band packing machine that can be banded to a package of various sizes in a band packing machine having a movable band guider and its driving means to move the band guider according to the size of the package.
