The left side panel 3c of the casing body 2 is composed of an upper tilting wall portion 58 and a lower fixed wall portion 59. As shown in FIG. The tilting wall portion 58 is coupled to the upper end portion of the fixed wall portion 59 via a coupling pin 56 at its lower end portion so as to be rotatable in the rotation direction Rb. That is, the upper end can be tilted outward. The tilting wall portion 58 has a pair of stopper arms 57 protruding toward the inside of the casing body 2 by a predetermined length on the inner surface side of the lower end portion. The tip of the stopper arm 57 is bent into a hook shape, and when the tilting wall portion 58 tilts, the hook hooks on the side edges of the front panel 3a and the rear panel 3b to limit tilting of the tilting wall portion 58.

[Replenishment of packaging bags]
The operator rotates the swing lid portion 10a around the hinge 51 in the rotation direction Ra to open the upper right end portion of the casing main body 2 . Next, the upper end of the tilting wall portion 58 in the upright position is grasped, and the tilting wall portion 58 is tilted outward in the rotation direction Rb to the tilted position. The upright and tilted positions correspond to the closed and open positions, respectively, since the tilting wall 58 opens and closes the interior of the casing, respectively.

Due to the outward rotation of the swing lid 10 a and the tilt wall 58 , the casing body 2 is formed with an opening in the region of the swing lid 10 a and the tilt wall 58 . Through this open portion, the hanger 55 becomes visible from the outside of the packaging apparatus 1, and the transparent plastic bag 25 can be replenished.

The worker sets the bundle 28 of the transparent plastic bags 25 on the hanger 55. - 特許庁The transparent plastic bag 25 is suspended from the hanger 55 by inserting the hanger 55 through the insertion hole 37 . The operator then rotates the tilting wall portion 58 in the rotational direction Rb around the coupling pin 56 to return it to the original upright position. Next, the swinging lid portion 10a is rotated in the rotational direction Ra about the hinge 51 and brought into contact with the upper end of the tilting wall portion 58, thereby closing the left upper portion of the casing body 2 with the swinging lid portion 10a.

[Operating Means and Connecting Means]
FIG. 3 is a diagram showing the operation means 60 as viewed from the side of the packaging device 1. As shown in FIG. Only the lower part of the coupling means 62 is shown in FIG. The operating means 60 and the connecting means 62 will be described with reference to FIGS. 2 and 3. FIG.

The operating means 60 includes a pedal 41, a rotating shaft 65, a standing plate 67 and an extension coil spring 70 as main components. The connecting means 62 comprises rolls 68, wires 73 and extension coil springs 74 as main components.

The pedal 41 is pivotally supported at its rear end so as to be rotatable in the rotation direction Rc about a left-right horizontal rotation shaft 65 having a predetermined height. The upright plate 67 has its lower end fixed to the upper surface of the pedal 41 and stands up from the upper surface. The extension coil spring 70 is engaged at its upper end with a shaft portion at the end of a horizontal bar 66 provided at the same height as the roll 68, and is engaged with the pedal 41 at its lower end. The horizontal bar 66 urges the pedal 41 upward in the rotational direction Rc.

When the operator steps on the portion of the pedal 41 that protrudes forward from the casing body 2 , the front end of the pedal 41 swings downward around the rotating shaft 65 against the biasing force of the extension coil spring 70 . Let When the operator releases the front end of the pedal 41 , the pedal 41 causes the front end to swing upward around the rotating shaft 65 according to the biasing force of the tension coil spring 70 . The pedal 41 abuts on the upper side edge of the pedal opening 42 and is held in a horizontal position.

In the connecting means 62 , the wire 73 is engaged at its upper end by the widening guide 93 of the forced opening means 53 and at its lower end by the upper end of the upright plate 67 of the operating means 60 . The wire 73 extends vertically along the back panel 3b, wraps around the roll 68, and is locked to the upright plate 67. As shown in FIG. A tension coil spring 74 is interposed in the middle of the wire 73 to prevent excessive operating force from acting on the operating means 60 .

When the operator does not step on the pedal 41, the pedal 41 is in a horizontal position. As a result, the upper end of the standing plate 67 is located on the back panel 3b side, and the amount of downward entrainment of the wire 73 is small. On the other hand, when the operator steps on the pedal 41, the upper end of the standing plate 67 moves toward the front panel 3a. As a result, the wire 73 descends in the range above the roll 68, and the downward entrainment amount of the forced opening means 53 by the wire 73 increases.

[Pressing means]
FIG. 4 is an enlarged view of the pressing means 54 seen from the front view of the packaging apparatus 1. As shown in FIG. The pressing means 54 is attached to the inner surface side of the tilting wall portion 58 on the base end side and tilts integrally with the tilting wall portion 58 . The pressing means 54 includes an upper link 81 , a lower link 82 and a pressing plate 85 . Base ends of the upper link 81 and the lower link 82 are rotatably supported by the upper elongated hole 77 and the lower elongated hole 78 of the tilting wall portion 58 . The tip of the upper link 81 is rotatably coupled to the intermediate portion of the lower link 82 . The pressing plate 85 is rotatably coupled to the tip of the lower link 82 .

When the tilting wall portion 58 is in the upright position, the pressing plate 85 is pressed against the lower end of the partition wall portion 50 from the hanger 55 side of the partition wall portion 50 . The inclination angle of the pressing plate 85 changes according to the thickness of the bundle 28 sandwiched between the lower end of the partition wall portion 50 and the pressing plate 85 .

FIG. 5 is a view of the dividing wall portion 50 and the upper end portion of the bundle 28 of the transparent plastic bags 25 viewed from the guide passage 47 side. For convenience of explanation, the foremost transparent plastic bag 25 (closest to the guide passage 47 side) among the plurality of transparent plastic bags 25 of the bundle 28 is denoted by reference numeral "25f".

In FIGS. 4 and 5, a bundle 28 of transparent plastic bags 25 is passed through a pair of insertion holes 37 by a hanger 55. As shown in FIG. As described above, the pressing means 54 presses the bundle 28 against the lower end of the partition wall 50 when the tilting wall 58 is in the upright position.

The pair of leaf springs 88 are fixed at their upper ends to the surface of the partition wall 50 on the side of the guide passage 47 , and their lower ends protrude downward from the lower end of the partition wall 50 to form the extending portions of the transparent plastic bags 25 of the bundle 28 . 31 is pressed toward the pressing plate 85 . As a result, the bundle 28 is pressed between the pressing plate 85 and the leaf spring 88 at the extending portion 31 of the transparent plastic bag 25 . At this time, the transparent plastic bag 25f is held at a position where the open end 29 of the transparent plastic bag 25f protrudes slightly from the right surface of the partition wall portion 50 toward the guide passage 47. As shown in FIG.

[Forced opening means]
6 and 7 are diagrams showing the forced opening means 53 in the first and second rotational positions, respectively. The forced opening means 53 has an expansion guide 93, a rotating shaft 94, a tongue piece 96, and torsion coil springs 98,99.

The expansion guide 93 is supported at its proximal end so as to be rotatable in the rotational direction Rd around the rotary shaft 94 so that its distal end faces the partition wall portion 50 side. The base end of the tongue piece 96 is coupled to the tip end of the expansion guide 93 so as to be rotatable about the rotation axis 97 in the rotation direction Re (shown only in FIG. 7). The tongue piece 96 has a tail portion 100 that protrudes from the rotating shaft 97 to the side opposite to the partition wall portion 50 side. The protruding end of the tail section 100 abuts on a stopper (not shown) on the lower surface side to prevent the tail section 100 from descending from the horizontal position.

The torsion coil spring 99 is wound around the rotating shaft 97 and has both ends in contact with the expanding guide 93 and the lower surface of the tongue piece 96 . The torsion coil spring 99 biases the tongue piece 96 against the expansion guide 93 in a direction in which the lower surface of the expansion guide 93 and the lower surface of the tongue piece 96 are expanded.

8 is a perspective view of the expansion guide 93. FIG. The spreading guide 93 has a tail 100 on the proximal side and a depending edge 106 that is bent towards the tongue 96 on the distal side. The tail portion 100 limits the rotation of the expanding guide 93 in the direction of rotation Rd, and the hanging edge 106 functions as a stopper that limits the rotation of the tongue 96 in the direction of rotation Re.

The expansion guide 93 further includes a substrate portion 102 in the center in the width direction (opposing direction of the front panel 3a and the rear panel 3b), lower protruding portions 103 on both sides of the substrate portion 102, and upper sides of the lower protruding portion 103. and an upper projecting portion 104 . The lower overhanging portion 103 is slightly inclined outward from the substrate portion 102 and rises. The upper overhanging portion 104 has a smaller outer inclination angle than the lower overhanging portion 103 and is coupled to the upper side edge of the lower overhanging portion 103 .

The tongue 96 has a proximal end coupled to the lower surface of the distal end of the base plate 102 via a rotating shaft 97 so as to be rotatable in the rotational direction Re. The side edges on both sides of the base end side of the base portion 102 do not have the lower projecting portion 103, and the expansion guide 93 is only the base portion 102 at the base end portion.

6 and 7, the upper end of the wire 73 of the connecting means 62 is locked to the lower surface of the tongue piece 96. As shown in FIG.

[Action of Forced Opening Means]
When the operator does not step on the pedal 41 , the expansion guide 93 does not receive downward operation force from the wire 73 . As a result, the expanding guide 93 is held in a horizontal position by the biasing force of the torsion coil spring 98 . That is, the forced opening means 53 is at the first pivot position shown in FIG. At the first pivot position, the tip of the tongue piece 96 is located above the open end 29 of the transparent plastic bag 25f and is in contact with the extending portion 31. As shown in FIG.

When the operator steps on the pedal 41 , the expansion guide 93 is dragged downward by the wire 73 . As a result, the expansion guide 93 rotates in the rotation direction Rd about the rotation shaft 94 against the torsion coil spring 98, and the tip side is lowered. Along with this, the tip of the tongue piece 96 slides downward on the extending portion 31 of the transparent plastic bag 25 . Then, the tip of the tongue piece 96 is inserted into the inner peripheral side of the open end 29 of the transparent plastic bag 25f, and further enters the bag portion 30. As shown in FIG.

As the amount of rotation of the forced opening means 53 about the rotation shaft 94 increases, the amount of insertion of the tongue piece 96 into the partition wall portion 50 increases, and the lower surface of the expanding guide 93 and the tongue piece 96 The crossing angle is also increased by the torsion coil spring 99 .

When the angle of intersection between the lower surface of the expanding guide 93 and the tongue piece 96 reaches a predetermined amount, the tongue piece 96 comes into contact with the hanging edge 106 and the angle of intersection stops increasing. Thereafter, the tip of the tongue piece 96 gradually moves away from the pressing plate 85 of the pressing means 54 as it rotates around the rotating shaft 94 . On the other hand, the leaf spring 88 presses the extending portion 31 of the transparent plastic bag 25f against the pressing plate 85. As shown in FIG. As a result, the transparent plastic bag 25f is forcibly opened at the open end 29 by the tongue piece 96. As shown in FIG.

The forced opening means 53 also rotates around the rotary shaft 94 . As a result, the distal end of the expansion guide 93 including the hanging edge 106 is also partially inserted into the transparent plastic bag 25f following the tongue piece 96. As shown in FIG. Thus, when the forcible opening means 53 reaches the second rotation position in FIG. 7, the transparent plastic bag 25f is positioned at the open end 29 in the width direction (horizontal direction in FIG. 5) and the thickness direction (horizontal direction in FIG. 7). It is expanded by the expansion guides 93 in both directions, and a wide opening is maintained.

When the operator keeps stepping on the pedal 41, the forced opening means 53 is held at the second rotational position shown in FIG. When the operator drops the calendar 15 from the insertion opening 14 of the casing main body 2 in this state, the calendar 15 descends the guide passage 47 by gravity. It is guided to the opening of the transparent plastic bag 25f by the expansion guide 93, and is also guided into the bag portion 30 of the transparent plastic bag 25f at the leading end of the expansion guide 93. As shown in FIG.

As a result, the calendar 15 is loaded into the bag portion 30 of the transparent plastic bag 25f. After that, as described above for the overall operation of the packaging apparatus 1, the operator puts one hand into the outlet 19 and pulls down the bag portion 30 of the transparent vinyl bag 25f. As a result, the transparent plastic bag 25 is vertically divided at the perforations 38 .

Next, the worker pulls out the transparent vinyl bag 25f with the calendar 15 loaded in the bag portion 30 from the outlet 19. As shown in FIG. FIG. 9 shows the dimensional relationship of each part of the transparent plastic bag 25 when pulled out from the outlet 19. As shown in FIG.

In FIG. 9, each code is defined as follows. The longitudinal dimension of the transparent plastic bag 25 is called "length", and the widthwise dimension of the transparent plastic bag 25 is called "width".
La: length of transparent plastic bag 25 between perforation 38 and upper end of calendar 15 in bag portion 30 Lb: length between opening end 29 and perforation 38 Lc: opening end 29 and bag portion 30 Length Wa between the inner calender 15 and the upper end: the outer diameter (diameter) of the calender 15 loaded in the bag portion 30 in a scroll shape
Note that La=Lb+Lc.

For the transparent plastic bag 25 containing the calendar 15 taken out by the operator from the take-out port 19, the transparent vinyl is preferably placed so that the relationship La>Wa is established, more preferably the relationship 2Wa>La>Wa is established. The dimensions of bag 25 are set. Note that Lc is preferably 2 cm or more, more preferably 3 to 6 cm.

With such a dimensional regulation, when the cover portion as the portion of the transparent plastic bag 25 above the roll-shaped calendar 15 in the bag portion 30 of the transparent plastic bag 25 covers the upper end surface of the calendar 15, the cover portion is guaranteed to be larger than the size of the top surface of the calender 15 . Thereby, the cover portion can be inserted into the inner peripheral surface side of the bag portion 30 from the upper end side thereof so that the upper end surface of the roll-shaped calendar 15 can be sealed within the bag portion 30 .

[Modification]
In the embodiment, the perforations 38 of the transparent plastic bag 25 are separated by an operator inserting one hand from the take-out port 19 and pulling downward the transparent plastic bag 25 after the calendar 15 is loaded. . Alternatively, the transparent plastic bag 25 may be automatically divided within the packaging apparatus 1 according to the weight of the calendar 15 when the calendar 15 is loaded into the transparent plastic bag 25 . In this case, the fact that the insertion hole 37 and the perforation 38 are formed at the same position in the longitudinal direction of the transparent plastic bag 25 is advantageous for automatic separation of the perforation 38l. This is because the presence of the insertion hole 37 sufficiently reduces the binding force at the longitudinal position of the perforation 38 .

In the embodiment, a roll-shaped calendar 15 is described as an example of the roll-up sheet. The roll-up sheet of the present invention may be a roll-shaped sheet such as a poster. In addition, it is preferable that the roll sheet has a long shape.

In the embodiment, a tongue piece 96 is employed as the insert piece. The insertion piece of the forcible opening means of the present invention may be a nail or other means as long as it rotates to forcibly open the opening end of the packaging bag.

In the embodiment, as the pressing means of the present invention, the pressing plate 85 is pressed against the lower end of the partition wall portion 50 by a link mechanism including the upper link 81 and the lower link 82 . The pressing means of the present invention can also press the pressing plate against the partition wall by using a biasing means such as a spring instead of the link mechanism.

In the embodiment, the tilting wall portion 58 is arranged on the left side of the packaging device 1 when viewed from the front. Therefore, the tilting wall side as one of the left and right sides of the present invention is the left side. However, the tilting wall side of the present invention can also be on the right side.
