In order to fully understand the present invention, preferred embodiments of the present invention will be described with reference to the accompanying drawings. Embodiments of the present invention may be modified in various forms, and the scope of the present invention should not be construed as being limited to the examples described in detail below. This embodiment is provided to more completely explain the present invention to those skilled in the art. Therefore, the shapes of elements in the drawings may be exaggerated to emphasize a clearer explanation. It should be noted that in each drawing, the same members are sometimes indicated by the same reference numerals. Detailed descriptions of well-known functions and configurations that may unnecessarily obscure the subject matter of the present invention are omitted.

The packaging device according to the present invention can be defined as including a receiving part 1, a cutting part 2, and a packing part 3, as shown in FIG.

The accommodating unit 1 sorts and stores the package inside the wrapping paper P, one side of which is open. Meanwhile, the package in this embodiment can be understood as a comprehensive concept including various products, and in the following embodiments, the package is assumed to be a bound spring notebook for convenience.

In the accommodating unit 1, a plurality of notes are continuously aligned and stored in the wrapping paper P unwound with one side open, and in the cutting unit 2, both ends of the wrapping paper P around the notes aligned and housed in the wrapping paper P is heat-sealed to form a wrapping paper P in the form of a pouch, and in the packaging unit 3, the open portion of the wrapping paper P in this state is folded and attached to the surface of the wrapping paper P to close the open portion to wrap the packaging. The process to complete is performed.

Prior to the description of the invention, for convenience of explanation, if the direction standard of the cutting part 2, which is not strict, is specified with reference to the accompanying drawings, in the state shown in FIG. In the description related to, the direction is specified and described according to this criterion.

First, the cutting unit 2 is installed on the right side of the storage unit 1 to receive the wrapping paper P (the state in which the package is stored) passing through the storage unit 1 and heat the wrapping paper P being transferred in a row. Both ends of the wrapping paper (P) are cut and bonded simultaneously to converge both ends of the wrapping paper (P).

To this end, the cutting unit 2, as shown in FIGS. 2 and 3, has a fusing unit 100 for sequentially heat-sealing both left and right ends of the wrapping paper P with the package in the center and the fusing unit 100. It may be installed on the right side and include a support conveyor 200 that supports the wrapping paper P from the bottom and transfers the wrapping paper P formed in the form of a pouch by the fusing unit 100 in a row.

On the other hand, the wrapping paper P passing through the fusing unit 100 may be folded in half as shown in FIG. 10 and accommodate notes therebetween. That is, the fusing unit 100 heat-seals and cuts the left and right wrapping paper P of the note to continuously divide and configure the pouch-shaped wrapping paper P.

The fusing unit 100 and the support conveyor 200 may be arranged in a line, and the pouch-type wrapping paper P may be transported toward the packaging part 3 by the support conveyor 200 while accommodating notes.

For example, as shown in FIGS. 3 and 5, the fusing unit 100 is installed to be reciprocating up and down in the vertical guide bar 110 extending vertically and the vertical guide bar 110, and A fusing member 120 that heats and then cools the wrapping paper P, a support member installed to be reciprocally movable up and down in the vertical guide bar 110 and supporting the fusing member 120 at the lower part of the fusing member 120 (130), the driving member 140 for synchronously driving the fusion bonding member 120 and the support member 130 in a facing direction or in a spaced direction with the wrapping paper (P) in between, and the cooling by the fusion bonding member 120 It may be illustrated as including an air supply member for supplying compressed air.

The fusion member 120 and the support member 130 are arranged to face each other at the upper and lower portions with the wrapping paper P interposed therebetween, and can ascend and descend along the vertical guide bar 110 .

The lower end of the vertical guide bar 110 may be mounted on the support block 150, and the support block 150 is connected to the horizontal guide bar 160 extending in the left and right directions to reciprocate left and right. Although not shown, the fusing unit 100 further includes a linear guide structure for reciprocating the support block 150 left and right, and the support block 150 along the longitudinal direction of the horizontal guide bar 160 by the linear guide. ) is moved, the fusing member 120, the support member 130, etc. may also be reciprocated in the left and right directions along the conveying direction of the wrapping paper P in conjunction with it.

When the wrapping paper P is put between the fusing member 120 and the support member 130, the fusing member 120 and the supporting member 130 move in a direction facing each other, for example, the fusing member 120 descends and supports The members 130 rise and come into contact with each other with the wrapping paper P interposed therebetween, and in this process, the wrapping paper P is heated so that it can be heat-sealed and cut.

When the thermal fusion cutting is completed, the fusion member 120 and the support member 130 may move in opposite directions and be spaced apart from each other.

In the present description, heat fusion cutting means that the wrapping paper P is folded in half while being melted by heat, and the overlapping wrapping paper P is convergently joined in one line and separated from the wrapping paper P at the same time.

In particular, the fusion member 120 melts the wrapping paper P by applying heat to the wrapping paper P for thermal fusion cutting of the wrapping paper P, and at this time, by rapidly cooling the molten portion, the thermal fusion cutting portion can be stabilized.

If the heat-sealed cutting area is not rapidly cooled, the area to be convergently joined may be opened or adhered to the support conveyor 200, which causes packaging defects.

In this way, in order to perform the thermal fusion cutting and cooling of the wrapper P at the same time, the fusion member 120 is fused through the fusion frame 121 installed on the vertical guide bar 110 and the connecting rod 122a. A cutter 122 installed at a lower portion of the frame 121 at a predetermined interval and heated to a predetermined temperature, and a cover 123 whose lower end is opened to expose the lower end of the cutter 122 while accommodating the cutter 122 therein , The spray nozzle 124 installed at the lower end of the cover 123 and spraying the cooled compressed air supplied from the air supply member to the surface of the wrapping paper P, and the fusing frame 121 and the cover 123 It may be illustrated as including a first buffer spring 125 installed between and elastically pressing the cover 123 in the direction of the support member 130 .

First, the fusing frame 121 may be guided up and down along the vertical guide bar 110 and support the cutter 122 and the cover 123 downward.

The cutter 122 and the cover 123 can move up and down in conjunction with the fusing frame 121 while being supported by the fusing frame 121, and in the case of the cutter 122, the wrapping paper P in contact with the bottom is melted. It has an electric heating circuit that can be heated to a certain temperature as much as possible. The lower end of the cutter 122 protrudes to the lower end of the open cover 123 when the fusing frame 121 reaches the bottom dead center and can come into contact with the support member 130, and the fusing frame 121 reaches the top dead center. When the cover 123 can be completely accommodated inside.

The cover 123 may be elastically supported on the lower portion of the fusing frame 121 via the first buffer spring 125, and in this state accommodate the cutter 122 inside.

A pair of support walls 123a facing each other in parallel may be formed at the lower end of the cover 123, and the lower end of the cutter 122 may be interposed between the pair of support walls 123a.

The injection nozzles 124 may be provided as a pair each formed at the lower end of the pair of support walls 123a, and inject compressed air in directions facing each other. Although not shown, each of the pair of injection nozzles 124 may have nozzle holes through which compressed air is injected in directions facing each other.

The lower ends of the pair of supporting walls 123a may come into contact with the support member 130 when the fusing frame 121 reaches the bottom dead center, and is separated from the supporting member 130 when the fusing frame 121 reaches the top dead center. It can be.

At the bottom dead center of the fusing frame 121, the cover 123 is in a state of being elastically pressed downward by the first buffer spring 125 while being in contact with the support member 130, and in this state, the fusing frame 121 Even if it rises to this certain height, since the cover 123 is in a state of being elastically pressed downward by the first buffer spring 125, the cover 123 has a structure that does not separate from the support member 130.

On the other hand, in the case of the cutter 122, when the fusing frame 121 rises, it can be moved upward in the cover 123 in conjunction with it.

That is, when the fusing frame 121 rises, the cutter 122 and the cover 123 rise in association with it. In the case of the cover 123, even if the cutter 122 is separated from the wrapping paper P, the wrapping paper P ) can be maintained for a certain period of time.

Therefore, when the fusing frame 121 rises, the cover 123 rises with a time difference from the cutter 122, and the space to be sprayed with compressed air between the pair of support walls 123a and the appropriate timing for sprayed compressed air can be obtained.

For example, as shown in FIG. 8, when the fusing frame 121 rises only to the first height at the bottom dead center of the fusing frame 121, the cutter 122 is spaced apart from the wrapping paper P supported by the support member 130. And the cover 123 is elastically pressed by the first buffer spring 125 to come into contact with the wrapping paper P supported by the support member 130, and in this state, the cooled compressed air blows through the spray nozzle ( 124) to be sprayed.

In this way, the wrapping paper P supported by the support member 130 can be fixed on the support member 130 by pressing the cover 123, and the cutter 122 rises to form a pair of support walls 123a. When the space between them is secured, compressed air is sprayed to provide a structure that can quickly cool the heat-sealed cutting area.

In particular, when the wrapping paper is made of OPP material, if cooling is not performed quickly, thermal fusion cannot be achieved.

Therefore, even if compressed air is injected into the wrapping paper (P), the wrapping paper (P) is not easily disturbed, and since the compressed air is injected in the space between the pair of support walls (123a), the compressed air is blown inside the cover (123). Since it can be used for cooling the heat-sealed cutting area without loss in the cooling process, the cooling efficiency is greatly improved.

Next, the support member 130 is installed on the lower side facing the fusing member 120 to simultaneously support the wrapping paper P and the fusing member 120 upward, and in addition, the wrapping paper delivered to the support conveyor 200. By supporting the bottom of the free end of the note in (P), it is possible to have a structure that prevents the note from being thermally fused and cut in a struck state.

To this end, the support member 130 is installed on the support frame 131 installed on the vertical guide bar 110, the upper portion of the support frame 131, and the cutter 122 and the cover 123 are in contact A fixed support 132, a movable support 133 spaced apart in parallel to the right side of the fixed support 132, and installed between the movable support 133 and the support frame 131 to lower the movable support 133 It may be exemplified as including a second buffer spring 134 that elastically supports in.

First, the support frame 131 may be guided up and down along the vertical guide bar 110, and supports the fixed support 132 and the movable support 133 upward.

The fixed support 132 and the movable support 133 can move up and down in conjunction with the support frame 131 while being supported by the support frame 131. In particular, in the case of the movable support 133, the support conveyor 200 ) has a structure in which upper movement is restricted at a height of

The fixed support 132 is integrally provided with the support frame 131 to provide an area where the fusing member 120 and the wrapping paper P are supported, and in the case of the movable support 133 via the second buffer spring 134. It serves to prevent the bottom of the note from drooping by being provided to be elastically pressed on the support frame 131 so that the free end portion of the note is supported.

On the other hand, the thermal fusion cutting of the wrapping paper (P) should be formed on the left and right sides of the note, respectively, so that a single wrapping paper (P) in the form of a pouch is formed. When doing this, there may be a concern that the left end of the note will be struck downward in the space between the fusion unit 100 and the support conveyor 200. At this time, the left end of the note is supported by the movable support 133, Heat-sealing cutting can be performed accurately.

When the support frame 131 rises in the direction facing the fusing member 120, the fixed support 132 rises in conjunction with this to be in contact with the cutter 122 and the cover 123, and the movable support 133 In the case of the upper movement is limited by the stopper 210 formed at the left end of the support conveyor 200 to limit the upper movement of the movable support 133, so that the left end of the note is supported on the same line as the support conveyor 200 can

At this time, even if the upper movement of the movable support 133 is limited by the stopper 210, in the case of the fixed support 132, the upper movement can be allowed to a certain height up to the compression limit of the second buffer spring 134. Accordingly, The fixed support 132 and the movable support 133 may form a height difference h1 up and down at the time when the thermal fusion cutting of the wrapping paper P is performed, and thus, the thermal fusion cutting is performed at the upper and lower center of the note. can be accurately formed.

Next, the driving member 140 serves to lift and lower the fusing frame 121 of the fusing member 120 and the support frame 131 of the supporting member 130 in synchronization with each other.

To this end, as shown in FIG. 4, the drive member 140 is mounted on the step motor 141 installed below the support member 130 and rotates in the forward and reverse direction, the main shaft 142, the main shaft 142 Connecting bracket 143 to be mounted, one end is rotatably mounted to the fusion frame 121, the other end is rotatably mounted to the connecting bracket 143 first rod 144 and one end to the support frame 131 It is rotatably mounted, and the other end may be exemplified as including a second rod 145 rotatably mounted to the connecting bracket 143.

That is, when the step motor 141 rotates the main shaft 142, the connecting bracket 143 rotates, and thus, the first rod 144 and the second rod 145 are fused on the vertical guide bar 110. It is possible to linearly move the frame 121 and the support frame 131, respectively.

That is, since the rotational motion of the main shaft 142 is converted into a linear motion, the fusing member 120 and the supporting member 130 can move up and down in synchronization in a direction facing each other or in a direction spaced apart from each other.

Since the driving member 140 can be designed in various ways along the line capable of moving the fusing member 120 and the support member 130 up and down, a detailed description thereof will be omitted.

The air supply member may be composed of a compressor and a pipe connecting the compressor and the spray nozzle 124, and may be provided in various ways in a line capable of supplying compressed air to the spray nozzle 124, so detailed descriptions below should be omitted.

Hereinafter, with reference to the accompanying drawings, the operation of the cutting unit 2 will be described. In this action, a process in which the fusion member 120 and the support member 130 are driven for thermal fusion cutting of the wrapping paper P will be described as an example.

First, when the wrapping paper P enters between the fusion splicing member 120 and the support member 130 spaced apart from each other vertically, as shown in FIG. 6, the fusion splicing member 120 and In the direction in which the support members 130 face each other, for example, the fusing member 120 moves downward and the support member 130 moves upward in synchronization with each other.

At this time, when the lower end of the cover 123 first contacts the fixing support 132, and then the fusing frame 121 moves to the bottom dead center, as shown in FIG. Penetrate through (P) to complete the thermal fusion cutting on the wrapping paper (P).

Subsequently, as shown in FIG. 8 , when the fusing frame 121 rises to the first height, the cutter 122 rises in association with it and is spaced upward from the fixed support 132 . Meanwhile, the cover 123 is in a state of pressing the wrapping paper P from the top, and this state may be maintained for several seconds.

Subsequently, the air supply member supplies compressed air toward the spray nozzle 124, and thus, the compressed air is sprayed into the space between the opposing support walls 123a, so that the heat-sealed cutting area can be quickly cooled.

When the cooling of the heat-sealed cutting part is completed, the fusion member 120 and the support member 130 are moved to the original position in the state shown in FIG. It can be supplied to the packaging part 3 side by the support conveyor 200.

Hereinafter, the accommodating unit 1 will be described with reference to the accompanying drawings.

Prior to the description of the present invention, for convenience of explanation, if the direction standard of the non-rigid housing unit 1 is specified with reference to the accompanying drawings, it is divided into up and down, left and right in the state as shown in FIG. 1, and other drawings In the description related to, the direction is specified and described according to this criterion.

First, as shown in FIGS. 9 and 11 , in the storage unit 1, notes are accommodated between the feeder 10 that supplies the wrapping paper P at a constant speed and the wrapping paper P supplied by the feeder 10. When the wrapping paper (P) and notes are transferred in a row, the transfer conveyor (20), installed on the path of the transfer conveyor (20), and the release paper (S) of the wrapping paper (P) transported by the transfer conveyor (20) While being transported by the release paper separation unit 30 and the transfer conveyor 20 for separating the notes, the edges of the notes exposed to one open side of the wrapping paper P are pressed to push the notes to the other side of the wrapping paper P to align It may be exemplified as including an alignment unit 40 .

The feeder 10 includes a plurality of supply rollers on which the wrapping paper P is wound in a roll form, and the wrapping paper P can be unwound at a constant speed from the supply roller and supplied to the transfer conveyor 20 .

In particular, the wrapper P supplied by the feeder 10 is configured to be folded in half as shown in FIG. 10 so that one side of the opposite side where the folding point is formed can be formed open for inserting a note. In addition, at least one portion of one end of the wrapping paper (P) folded in half and divided into two parts is formed relatively long to form an adhesive piece (M), and an adhesive line (L) is formed along the longitudinal direction of the adhesive piece (M2). Formed and this adhesive line (L) can be supplied to the transfer conveyor 20 in a state covered with release paper (S).

The wrapping paper P supplied by the feeder 10 passes through the path changing member 11 in the form of a triangular shape installed on the top of the transfer conveyor 20, and the path is changed parallel to the moving direction of the transfer conveyor 20, so that the transfer conveyor (20) can be supplied.

Notes are accommodated in one open portion of the wrapping paper P supplied to the transfer conveyor 20, and at this time, the supply of notes may be performed manually, or a separate means for sequentially supplying notes may be provided.

The conveying conveyor 20 may have the form of a known conveyor belt structure on a line capable of conveying the wrapping paper P in which the notes are stored in a row, for example, a frame constituting the exterior of the conveying conveyor 20, the It consists of a plurality of rollers mounted on the frame, a belt wound on the plurality of rollers in an endless track, and the like, and may further include a structure for imparting vacuum adsorption force to the conveyor belt, if necessary.

Accordingly, a structure in which the wrapping paper P is transferred to the top of the transfer conveyor 20 in an adsorbed state may be provided.

When the wrapping paper (P) transported on the transfer conveyor 20 passes through the release paper separation unit 30, it can be transported in a state where the release paper S is separated by the release paper separation unit 30.

In the setting process for the start-up of the packaging machine, the operator arbitrarily separates a certain portion of the release paper (S) of the wrapping paper (P), and interlocks the separated release paper (S) between the release paper separation unit (30) and the alignment unit (40). When the transfer conveyor 20 is driven in this state, the release paper S can be continuously separated from the wrapping paper P while the wrapping paper P is being transported in a row.

The release paper separation unit 30 is provided with a separation piece 31 in which a passage groove 32 through which the release paper S passes is cut, and the release paper S separated from the wrapping paper P through the passage groove 32 is provided. It may be guided and configured to be spaced apart from the wrapping paper (P).

The release paper S guided through the passage groove 32 may be separately collected through the alignment unit 40 .

The alignment unit 40 has a structure capable of separately collecting the release paper S separated from the wrapping paper P, in addition to correctly aligning the notes into the wrapping paper P.

To this end, the alignment unit 40 is installed rotatably in place on the support 41 installed on the upper part of the transfer conveyor 20 and the support 41, and the release paper separating unit 30 removes the wrapping paper P from the A pair of pulleys (42) on which the separated release paper (S) is wound in an endless track, a pad (43) mounted on the bottom of the pair of pulleys (42) and elastically contacted with the edge of the note, and It may be exemplified as including a winch 44 for pulling and winding the release paper S discharged from the pair of pulleys 42 .

The release paper (S) separated from the wrapper (P) by the release paper separation unit (30) is first wound around a pair of pulleys (42) in an endless orbit and is primarily guided, and then the pair of pulleys (42) and the original tooth ( 44) to be guided secondary to the idle pulley 42' provided between them and discharged to the original tooth 44 side.

In particular, the pair of pulleys 42 can be rotated in place without the configuration of a motor that generates a separate power.

For example, since the pair of pulleys 42 are configured to be rotated in place by the tensile force of the release paper S wound around the wheel 44, a separate motor can be omitted, thereby greatly simplifying the structure. have

Since the release paper S winds the pair of pulleys 42 in an endless orbit, each of the pair of pulleys 42 can rotate at synchronous speeds and directions.

The pair of pulleys 42 serve to rotate the pad 43 mounted therein in one direction while rotating. In addition, the position of the pulley 42 needs to be finely adjusted while supporting the pad 43 depending on the situation. If it is designed to include a motor for self-rotation, the structure becomes very complicated, so, The degree of freedom in the design of the alignment unit 40 is lowered, and manufacturing costs are significantly increased.

Therefore, in the present embodiment, the release paper (S), which must be separated from the wrapping paper (P) and discharged separately, is actively utilized and configured to be wound around the pair of pulleys (42) in the form of an endless track, thereby rotating the pair of pulleys (42). In doing so, the release paper (S) itself serves as a power transmission medium without the need to configure an additional power source such as a motor, so that power can be used efficiently without unnecessary loss, and furthermore, the design freedom of the alignment unit 40 is increased. and greatly simplify the structure of the alignment unit 40.

The pads 43 mounted on the bottom of each of the pair of pulleys 42 rotate in synchronization with the pulleys 42 and directly contact the notes transported in a row by the transfer conveyor 20 to transfer the notes into the wrapping paper P. acts as a push.

On the other hand, the note stored in one open portion of the wrapping paper P may not be completely stored inside the folded wrapping paper P depending on circumstances.

For example, as shown in FIGS. 12 and 13, in the case of notes before passing through the alignment unit 40, more specifically, the pad 43, the notes are not completely accommodated in the other side of the wrapping paper P, and some of the edges of the notes It frequently occurs that is somewhat poorly aligned, such as being exposed to one side of the open wrapping paper (P).

On the other hand, in the packaging unit 3, the packaging is completed by folding the adhesive piece (M) of the wrapping paper (P) onto the surface of the wrapping paper (P) and attaching the adhesive line (L) to the outer surface of the wrapping paper (P). (The state shown in FIG. 13A), the adhesive piece (M) is pressed by the exposed note, so that the adhesive piece (M) cannot be properly folded to the outer surface of the opposite wrapping paper (P), or the adhesive piece (M) is properly folded Even if it does, the adhesive line (L) is not always attached at the same point, causing a problem of deterioration in marketability. Severely, a problem that a note is attached to the adhesive line (L) and a defect occurs follows.

Accordingly, the pad 43 contacts the edge of the notes being transported in a row and pushes the exposed notes to one side of the opened wrapping paper P so that the notes are perfectly stored in the folded wrapping paper P.

That is, when the edge of the note is exposed to one open portion of the wrapping paper P while the note is being conveyed by the transfer conveyor 20, the exposed corner contacts the pad 43 and the pad 43 at the same time By being pushed to the other side, the note can be positioned deep inside the wrapping paper (P).

In particular, since the pad 43 is rotated by the pulley 42, it has a structure in which it is in rotational contact with the notes conveyed in a row on the transfer conveyor 20. Thus, even if the note is in contact with the pad 43 during transport, the note can be stored inside the wrapping paper P without being twisted eccentrically.

For example, taking as an example that notes are transferred from left to right based on FIG. 12, the pad 43 rotates in the right direction, that is, clockwise, so that the pad 43 moves the transfer conveyor 20 when it contacts the note. It is preferable in terms of not interfering with the one-way linear transfer of knots through.

In addition, since the pad 43 comes into contact with the edge of the book after binding, it is preferable to apply minimal external force to the note in order not to degrade the note's marketability.

To this end, each of the pair of pads 43 is formed in the form of a disk made of a sponge material, so that when the pad 43 comes into contact with the note, it is elastically deformed and the impact is absorbed by the pad 43 to make the note. It has a structure that prevents it from being damaged.

The wheel 44 is installed at the bottom of the transfer conveyor 20 and rotates in place by a separate drive motor to pull the release paper S via a pair of pulleys 42 and wind it to the outer circumference.

Tensile force may act on the release paper S separated from the wrapper P by the wheel 44, and thus, as long as the release paper S is wound around the wheel 44, the release paper S is wound in an endless orbit. A structure in which the pair of pulleys 42 can be rotated in place is provided.

On the other hand, notes can be bound in various sizes depending on the type. If the length of the top and bottom of the note becomes longer or shorter, the position of the pad 43 to contact the edge of the note also needs to be adjusted accordingly. have.

Accordingly, the position of the pad 43 can be adjusted according to the size of the note by moving the support 41 itself that rotates the pulley 42 in the forward and backward directions (up and down with reference to FIG. 15).

As a configuration for this, the support 41 is a fixing member 45 fixedly installed on the top of the conveying conveyor 20, and the wrapping paper P transported on the conveying conveyor 20 in a state in contact with the fixing member 45 The first support bar 46a extending toward the front and rear through which the slats 46c pass, and extending in a direction orthogonal to the first support bar 46a from the end of the first support bar 46a, but lower both ends. The bracket 46 including the second support bar 46b for rotationally supporting the furnace pulley 42 and the slat 46c and the fixing member 45 are mutually penetrated and fastened to fix the bracket 46 to the fixing member ( 45) may be illustrated as including a screw handle 47 that is fixedly coupled to the top.

The fixing member 45 is integrally formed on the upper surface of the transfer conveyor 20 and is provided so as not to move, and has a fastening hole (not shown) for fastening the screw handle 47.

The bracket 46 has a substantially 'T'-shaped structure by a combination of the first support bar 46a and the second support bar 46b, and can be relatively moved in the forward and backward directions on the fixing member 45.

The slats 46c formed on the first support bar 46a are provided in the form of long holes extending in the forward and backward directions and allow the movement of the bracket 46 in the forward and backward directions.

A pair of pulleys 42 may be rotatably mounted at both ends of the second support bar 46b via bearings, respectively.

The screw handle 47 has a structure in which a screw body is formed at the bottom so as to be screwable into the fastening hole and a handle is provided at the top of the screw body so that the user can grip it by hand.

That is, when the screw handle 47 is strongly screwed into the fastening hole, the handle itself has a structure that strongly compresses the bracket 46 from the top, so that the bracket 46 is restrained on the line where the positional movement of the bracket 46 is restricted. Conversely, when the screw handle 47 is released from the fastening hole, the handle is separated from the bracket 46 and the bracket 46 is restrained by the pulley 42.

In summary, since the bracket 46 is configured to be position-adjustable back and forth along the longitudinal direction of the slat 46c according to the length of the note, as a result, the position of the pad 43 supported by the bracket 46 is adjusted to that of the note. It becomes a structure that can be adjusted according to the length, and therefore, even if notes of different lengths are packed, the pad 43 always contacts the note at the same position relative to the note, so that the notes can be aligned and stored in the wrapping paper P .

Hereinafter, the operation of the storage unit 1 will be described. In this action, the process of sorting and storing notes into the wrapping paper (P) will be described as an example together with the process of operating the storage unit (1).

First, the wrapping paper P is supplied to the transfer conveyor 20 through the feeder 10. The supplied wrapping paper P is transferred in a row by the transfer conveyor 20 via the path changing member 11 . At this time, the operator arbitrarily separates a certain portion of the release paper (S) of the wrapping paper (P) so that the release paper (S) of the wrapping paper (P) can be separated, and the separated release paper (S) is passed through the groove ( 32) and then wound around a pair of pulleys 42 in the form of an endless orbit, whereby the end is wound around the original tooth 44 to complete the setting. Thus, the release paper (S) can be continuously separated from the wrapping paper (P) while the wrapping paper (P) is being transported in a row.

Subsequently, a plurality of notes are inserted at regular intervals into the open portion of one side of the wrapping paper P passing through the path changing member 11 . Accordingly, when the wrapping paper P is transferred on the transfer conveyor 20, the notes stored therein are also transferred in the same direction.

In the meantime, notes with poor alignment of the notes, for example, notes whose corners are partially exposed to the open side of the wrapping paper P, are placed on the path of the conveyor 20 and come into contact with the pad 43 rotating in place. It can be completely accommodated and aligned inside the wrapping paper (P).

The wrapping paper (P) and the note, which have been sorted and stored in this way, are put into the cutting unit (2), and both ends of the wrapping paper (P) around the note are heat-sealed and cut to form a pouch, and the pouch-shaped wrapping paper (P) is ), the adhesive piece (M) is folded so that the open portion of the wrapping paper (P) is closed, and then the adhesive line (L) is attached to the outside of the wrapping paper (P) to complete the wrapping process of the note.

In summary, the storage unit actively utilizes the release paper, which must be separated from the wrapping paper and discharged separately, and is wound on a pair of pulleys in an endless track, so that there is no need to configure an additional power source such as a motor to rotate the pair of pulleys. By allowing itself to serve as a power transmission medium, power can be used efficiently without unnecessary loss, and furthermore, freedom in the design of the alignment unit can be granted and the structure of the alignment unit can be greatly simplified.

In addition, if the edge of the note is exposed to one open part of the wrapping paper while the note is being transported by the transfer conveyor, the exposed corner contacts the pad and is pushed to the other side by the pad at the same time, so the note goes deep inside the wrapping paper. Since it can be positioned, the note can be perfectly accommodated within the folded wrapping paper. As a result, the marketability of the packaged note product is improved, and the occurrence of defective products in the packaging process can be prevented.

Hereinafter, the packaging unit 3 will be described with reference to the accompanying drawings.

Prior to the description of the invention, for convenience of explanation, if the direction standard of the packaging part 3, which is not strict, is specified with reference to the accompanying drawings, in the state shown in FIG. In the description related to, the direction is specified and described according to this criterion.

The wrapping paper P supplied to the packaging unit 3 is formed in the form of a pouch by heat-sealing both ends of the cutting unit 2, and in particular, one side may be open while storing notes therein. . In addition, a long adhesive piece M is formed on one side of the pouch-shaped wrapping paper P, and an adhesive line L may be formed in the longitudinal direction of the adhesive piece M2.

The wrapping paper (P) configured as described above can be closed while being transported in a row in the packaging unit 3 with one open side facing the right side.

More specifically, the packaging unit 3 is between the first and second adsorption conveyors CB1 and CB2 and the first and second adsorption conveyors CB1 and CB2 that transport the wrapping paper P in a row while adsorbing the lower surface. It is installed and injects compressed air upward to bend the adhesive piece (M) passing between the first and second adsorption conveyors (CB1, CB2) upward. The adsorption member 400 installed on the upper side and adsorbing the adhesive piece M bent upward by the air blowing member 300 and the adsorption member 400 installed on the adsorption member 400 and adsorbed on the adsorption member 400 It may be exemplified as including a brush member 500 for attaching the piece (M) to the surface of the wrapping paper (P) by pressing it.

The first and second suction conveyors CB1 and CB2 are disposed adjacent to each other in a row on the left and right, and transfer the pouch-shaped wrapping paper P to the top. In order to prevent the wrapping paper (P) from being moved during the transfer process, the wrapping paper (P) can be transferred in a row while vacuum adsorbing the wrapping paper (P) by exerting an adsorption force downward.

The first suction conveyor CB1 may be installed adjacent to the cutting unit 2 to be described later, and may receive the heat-sealed and cut pouch-type wrapping paper P from the support conveyor 200 of the cutting unit 2.

Since the first and second adsorption conveyors CB1 and CB2 may follow a known vacuum adsorption type conveyor structure in a line capable of transporting objects in a row while vacuum adsorbing them, a detailed description thereof will be omitted.

Next, the air blowing member 300 injects compressed air upward from the lower part of the space provided between the first and second adsorption conveyors CB1 and CB2 to vertically bend the adhesive piece M in the form of a free end.

The air injection member 300 may be connected to a compressor (not shown) and may include a plurality of nozzles having an upward injection direction.

Since the air injection member 300 may be provided in various ways on a line capable of injecting compressed air from the bottom of the adhesive piece (M), a detailed description thereof will be omitted.

On the other hand, in the case of wrapping paper (P), since it is transported while being adsorbed on the first and second adsorption conveyors (CB1 and CB2), positional movement such as being eccentric or rotated on the first and second adsorption conveyors (CB1.CB2) can be suppressed. have. However, in the case of the note stored inside the wrapping paper (P), since it is not in a separate position-fixed state, there is a risk of being exposed to one side of the open wrapping paper (P) by moving by inertia during the transfer process.

For example, as shown in FIG. 13A, when a part of the note moves to one side of the open wrapping paper P and invades the adhesive piece M, the adhesive piece M is pressed by the exposed note and the adhesive piece M The outer surface of the wrapping paper P on the other side cannot be properly folded, or even if the adhesive piece M is properly folded, the adhesive line L is not always adhered at the same point, resulting in a decrease in marketability. Severely, a problem that a note is attached to the adhesive line (L) and a defect occurs follows.

Accordingly, in the adsorbing member 400 described later, by adsorbing and holding the vertically bent adhesive piece M at the top, the exposed note through the adhesive piece M can be pushed to the other side of the wrapping paper P, so that the adhesive Before the line (L) is contacted, the note is perfectly accommodated in the wrapping paper (P).

To this end, the suction member 400 may be exemplified as including an outer frame 410, a first suction pipe 420, a second suction pipe 430, and a connection hose 440.

First, the outer frame 410 is installed on top of the first and second suction conveyors CB1 and CB2, and constitutes the main skeleton of the suction member 400, and the first suction pipe 420 and the second suction pipe ( 430) can be supported.

The first suction tube 420 may be supported by the outer frame 410 directly above the air blowing member 300 . Subsequently, the first adsorption pipe 420 is formed in the form of a hollow tube, and has a first adsorption hole 421 on the lower surface and a second adsorption hole on the left side perpendicular to the surface on which the first adsorption hole 421 is formed. (422) may be formed.

When a suction force is applied to the inside of the first suction tube 420, external air is sucked into the first suction hole 421 and the second suction hole 422, and suction force may be generated.

A flat first suction surface 423 is formed on the outer lower surface of the first suction tube 420, and a second suction surface 424 is formed on the outer left surface. At this time, the first suction surface 423 The first suction hole 421 may be formed on the second suction surface 424 and the second suction hole 422 may be formed on the second suction surface 424 .

Accordingly, when the adhesive piece M is adsorbed to the outside of the first suction tube 420, the adhesive piece M comes into contact with the outside of the first suction tube 420 face-to-face, increasing the contact area, thereby increasing the adsorption efficiency. It can be further improved, and shape deformation of the adhesive piece (M) can be minimized.

In addition, the adhesive piece M may be adsorbed on at least two surfaces of the first suction pipe 420. At this time, as shown in FIG. Even when the length of is relatively long, it is possible to adsorb the adhesive pieces (M) bent vertically toward the top without difficulty. The adsorption action can be performed stably without destruction of the adsorbent. The step-by-step adsorption process of the adhesive piece M will be described in detail in the action of the packaging part 3 to be described later.

The brush member 500 may be installed adjacent to the right side of the first suction pipe 420 .

Next, the second suction pipe 430 is installed on the outer frame 410, and is directly connected to a suction motor (not shown separately) so that suction force is applied to the inside. Like the first suction tube 420, the second suction tube 430 may have a tube shape with an empty inside.

The connecting hose 440 connects the second suction pipe 430 and the first suction pipe 420 to apply a suction force to the first suction pipe 420 .

Meanwhile, a plurality of first suction holes 421 and second suction holes 422 may be formed in succession along the longitudinal direction of the first suction pipe 420, and the second suction pipe 430 and the connecting hose 440 ) plays a role of distributing and providing the adsorption force so that a uniform adsorption force is applied to the plurality of first adsorption holes 421 and the second adsorption hole 422.

That is, when the suction motor operates to configure the inside of the second suction pipe 430 in a vacuum low pressure state, the suction force is uniformly distributed and transmitted to the inside of the first suction pipe 420 through the connection hose 440, and the first suction pipe A more uniform suction force acts on the inside of the 420, and thus, a balanced suction force can be exerted in the first suction hole 421 and the second suction hole 422.

Therefore, by effectively preventing excessive or non-adsorption of the adhesive piece M in a specific portion, it is possible to prevent the specific portion of the adhesive piece M from being adhered in a folded or shrunken state.

On the other hand, the packaging unit 3 has a structure that can adjust the adsorption time or adsorption height of the adhesive piece (M) according to the thickness, length, etc. of the note to be packed.

For example, if the thickness of the note is relatively thin or thick, the vertical height of the first suction tube 420 can be adjusted accordingly, and if the length of the adhesive piece (M) or note is long or conversely short, the first suction tube By moving the 420 in the left and right directions, the adsorption time of the adhesive piece (M) can be adjusted according to the position of the adhesive piece (M).

To this end, the outer frame 410 is formed in the form of a square frame and includes a fixed frame 411 having rails 411a formed on the upper surface in the left and right directions, and a first frame connected to the rails 411a and installed slidably in the left and right directions. 1 movable frame 412, a second movable frame 413 which supports the first suction tube 420 and is installed on the first movable frame 412 so as to be able to adjust the height upwards and downwards, and the upper part of the first movable frame 413 A height adjustment handle 414 that is rotatably installed in the frame 412 and has a lower end screwed to the second movable frame 413 to pull the second movable frame 413 up and down as it rotates. ).

The fixed frame 411 serves as a fixed body, and the first movable frame 412 can slide in the left and right directions on the fixed frame 411 .

A guide member 412a may be formed on the first movable frame 412 in a vertical direction, and a second movable frame 413 may be connected to the guide member 412a and guided in a vertical direction.

Therefore, when the first movable frame 412 is moved along the rail 411a, the second movable frame 413 can also be moved in the left and right directions in conjunction with this, and at the same time, on the second movable frame 413 The supported first suction pipe 420 may also be moved in the left and right directions.

The height adjustment handle 414 is mounted through the first movable frame 412 and the second movable frame 413, and when the user arbitrarily rotates, the first movable frame 412 may be provided to rotate in place. .

Accordingly, when the height adjustment handle 414 is rotated, the second movable frame 413 may be raised or lowered along the screw section provided at the lower end of the height adjustment handle 414 .

Although not shown, a screw hole through which the lower end of the height adjustment handle 414 is screwed may be formed in the second movable frame 413 .

Hereinafter, the operation of the packaging unit 3 will be described with reference to the accompanying drawings. In this action, the process of closing the open portion of the wrapping paper P according to the driving of the wrapping part 3 will be described as an example.

First, the wrapping paper P received from the cutting unit 2 can be conveyed in a row along the first adsorption conveyor CB1, and in the meantime, as shown in FIG. 19A, the adhesive piece M of the wrapping paper P ) passes through a point between the first adsorption conveyor (CB1) and the second adsorption conveyor (CB2), the air injection member 300 injects compressed air from below.

As shown in FIG. 19B, by this compressed air, the adhesive piece M of the wrapping paper P is vertically bent upwards, and at the same time, the second adsorption hole 422 is the primary first will adsorb

In this state, when the wrapping paper P continues to move toward the second adsorption conveyor CB2, the remaining portion not adsorbed by the second adsorption hole 422 is adsorbed to the first adsorption hole 421 as shown in FIG. 20A. While doing so, the adhesive piece M is deformed into an approximate 'B' shape and is simultaneously adsorbed on at least two surfaces of the first adsorption tube 420 .

Subsequently, the wrapping paper P continues to move toward the second suction conveyor CB2, and the adhesive piece M pushes the notes into the wrapping paper P, and at the same time, the brush member provided on the right side of the first suction pipe 420 ( 500), as shown in FIG. 20B, the adhesive piece (M) adsorbed on the first suction tube 420 is pressed by the brush member 500 and separated from the first suction tube 420 to wrapper. (P) It is attached to the outer surface, and the brush member 500 sweeps the adhesive piece (M) and presses the adhesive line (L) to be adhered to the outer surface of the wrapping paper (P).

Thus, the open portion of the wrapping paper P can be completely closed by the adhesive piece M. The wrapping paper (P) whose opening is closed in this way can be discharged to the outside on the second adsorption conveyor (CB2).
