Description

  The present invention relates to a wrapping paper connecting apparatus and method that can be employed in a wrapping apparatus for wrapping articles, particularly medicines.

  Conventionally, for example, as a packaging device for packaging a medicine, a long wrapping paper wound around a roll is sequentially rewound and sealed at a predetermined interval to form a bag-like shape that opens only at one edge. In some cases, after opening the medicine, the opening is sealed and packaged.

  In such a wrapping apparatus, when the wrapping paper runs out, a new wrapping paper must be set again. Various methods have been proposed in order to simplify the operation.

  In a so-called single-type wrapping paper that is not folded in a state of being wound on a roll, it can be easily connected by overlapping the heat-welding surface (glue surface) and heat-sealing (for example, Patent Document 1). For this reason, there are products that are actually commercialized.

  On the other hand, in a so-called double type wrapping paper, which is wound in advance on a roll in two, the work of overlapping the heat-welding surface (glue surface) is troublesome. In addition, the wrapping paper needs to be heat-welded with a strength that can withstand the tensile force that acts when transported in the packaging process, but it may be insufficient. For this reason, although the structure of the following patent documents 2-4 has been proposed as a method of connecting double type wrapping paper, none has been realized yet.

  For example, Patent Document 2 includes a feeding unit that feeds the wrapping paper, a guiding unit that guides the fed wrapping paper to a predetermined position, and a pulling unit that pulls the leading end of the wrapping paper guided by the guiding unit. The configuration is disclosed.

  Patent Document 3 discloses a configuration in which the tip of the wrapping paper is gripped by the holding means and the wrapping paper held by the moving means is moved to a predetermined position.

  Further, Patent Document 4 discloses a configuration in which the rear end of the wrapping paper before replacement and the front end of the wrapping paper to be newly replaced are connected by a double-sided tape to continuously perform the wrapping operation. Has been.

  For example, in a medicine packaging device, a wrapping paper unwound from a roll is complicated in order to perform printing on the wrapping paper, injection of the medicine into the wrapping paper, thermal welding of the wrapping paper, etc. in a limited space. It is configured to travel in an intricate route.

  However, in the configuration described in Patent Document 2, it is necessary to feed and guide the wrapping paper until it reaches the drawing-in means. For this reason, when a wrapping paper runs out and a new wrapping paper is mounted, a very troublesome work that requires the tip portion to be inserted through such a complicated path and set again cannot be adopted.

  In the configuration described in Patent Document 3, a structure in which the holding unit is moved by the moving unit is essential. Therefore, it is impossible to adopt such a structure in a complicated route.

  Furthermore, in the configuration described in Patent Document 4, the connection of the wrapping paper with the double-sided tape must be performed manually, and it is difficult to connect appropriately. For this reason, it is expected that the connection is inclined or the connection state becomes insufficient. In this case, there is a problem that the wrapping paper is twisted and clogged or torn while moving along the path (for this reason, there is no product that has actually been commercialized).

  Therefore, the present invention provides a wrapping paper connection device that can be appropriately connected to the previous wrapping paper and smoothly transferred to the next wrapping operation even when the wrapping paper folded in advance is replaced. It is another object of the present invention to provide a wrapping paper connection method.

As a means for solving the above problems, the present invention provides:
A wrapping paper connecting device for connecting the terminal portion of the old wrapping paper, which is folded in two and wound on a roll, and sequentially rewinds and wraps the medicine, to the tip of the newly replaced new wrapping paper,
Positioning means for positioning the terminal end of the old wrapping paper and the tip of the new wrapping paper at a predetermined connection position;
The inner side of the end portion of the old wrapping paper and the front end portion of the new wrapping paper, which are positioned at the connection position by the positioning means, is used as a sticking surface, and is folded in half between the sticking surfaces of each wrapping paper. Insert the wrapping paper pieces with the outside as the sticking surface so that the folding positions of the wrapping papers coincide with each other, the sticking surface of the end of the old wrapping paper, the sticking surface of the wrapping paper piece, and the tip of the new wrapping paper And a wrapping paper connecting means for heat-welding each of the sticking surface of the part and the sticking surface of the wrapping paper piece .

  The wrapping paper piece may be partly heat-welded in advance to either the end portion of the old wrapping paper or the leading end portion of the new wrapping paper.

Further, the present invention provides a means for solving the above-described problems,
A wrapping paper connecting method for connecting a terminal portion of an old wrapping paper, which is folded in half and wound around a roll, and sequentially rewound and wraps the medicine, to the tip of the newly replaced new wrapping paper,
Positioning the terminal end of the old wrapping paper and the tip of the new wrapping paper at a predetermined connection position;
The inner end of the old wrapping paper positioned at the connection position and the front end of the new wrapping paper are folded inward, and the outer side of each wrapping paper is folded in half. Insert the wrapping paper piece as the sticking surface so that the folding positions of the wrapping papers coincide with each other, and stick the sticking surface of the end of the old wrapping paper, the sticking surface of the wrapping paper piece, and the tip of the new wrapping paper And a step of bringing the surface and the attachment surface of the wrapping paper piece into surface contact and performing heat welding.

  Further, according to the present invention, as a means for solving the above-described problems, the packaging device includes the wrapping paper connecting device having any one of the above-described configurations.

(1-2. Wrapping paper connection device)
Various methods can be adopted for the wrapping paper connecting device, and for example, it can be configured as follows.

(1-2-1. Bending method using the cut-off adhesive tape piece 41)
The wrapping paper connecting apparatus shown in FIGS. 3 to 9 is arranged in the vicinity of the upper side of the ink cartridge 10. As shown in FIG. 3, the wrapping paper connecting apparatus has a configuration in which a center stage 23 is provided between the first stage 21 and the second stage 22. The first stage 21 includes a first support plate 24 and a first presser plate 25 that is rotatably attached to one end thereof. The first support plate 24 is formed with a guide piece 26 made of a magnetic material that protrudes upward on both sides of the free end, and a bearing portion 27 that supports the first presser plate 25 is formed on the base side. The first presser plate 25 is formed with an operation piece 28 having a narrow width at the free end, and a relief part 29 is formed by notching from one side edge at an intermediate portion. Further, the first presser plate 25 is integrated with permanent magnets 30 at two locations on the front end side and the base side of the surface facing the first support plate 24. The second stage 22 has the same configuration as the first stage 21 and includes a second support plate 31 and a second presser plate 32 rotatably attached to one end thereof.

  As shown in FIG. 5, the center stage 23 includes a rotation plate 33 that is rotatably attached around a support shaft (not shown), and a slide plate 34 that is slidably attached to the rotation plate 33. . A guide hole 35 is formed at the center of the rotating plate 33, and two guide protrusions 36 are formed on both sides thereof. The slide plate 34 has a shaft portion (not shown) provided on the lower surface on one end side slidably attached to the guide hole 35, and both side portions are guided by the guide protrusions 36. Thereby, the slide plate 34 is slidable between the overlapping position where it overlaps the rotation plate 33 and the pulled-out position. On the upper surface of the slide plate 34, an alignment line 37 is drawn on the center line. As will be described later, the alignment line 37 is used to align the end of the wrapping paper 9 and the front end of the newly mounted wrapping paper 9. In place of the alignment line 37, a partition plate (not shown) with which the end of each wrapping paper 9 abuts may be provided. The partition plate may be provided so as to be rotatable in a direction orthogonal to the wrapping paper 9, and after the wrapping paper 9 is aligned, the partition plate may be retracted to a position where it does not get in the way. At one end of the slide plate 34, first locking claws 38 are formed at predetermined intervals in the width direction. Notches 39 are formed on both sides of the other end side of the slide plate 34, and the second locking claws 40 protrude from the edges. Each of the locking claws 38 and 40 is inclined to the inside of the slide plate 34 and can hold the adhesive tape piece 41. The pressure-sensitive adhesive tape piece 41 is folded in half at a crease formed in the center of a predetermined length of the pressure-sensitive adhesive tape. The center stage 23 preferably includes a lock mechanism (not shown) that cannot be rotated from the inclined position to the horizontal position unless the slide plate 34 is slid from the pulled-out position to the original overlapping position.

  The wrapping paper connecting device having the above configuration is used as follows.

  That is, when the end of the wrapping paper 9 (old wrapping paper 9a) is detected by a sensor (not shown), the conveyance of the wrapping paper 9 is stopped and the installation of a new wrapping paper 9 (new wrapping paper 9b) is prompted. If the user replaces the wrapping paper 9 with a new one, the end of the old wrapping paper 9a and the front end of the new wrapping paper 9b are picked with a finger and set to the wrapping paper connecting device.

  In the wrapping paper connecting device, as shown in FIGS. 3, 9A, and 9B, the center stage 23 is set in the horizontal position in advance, and the first press plate 25 and the second press plate of the first stage 21 and the second stage 22 are used. The presser plate 32 is rotated to the upper open position. Then, as shown in FIG. 9C, the end of the old wrapping paper 9 a is aligned with the alignment line 37 formed on the slide plate 34 of the center stage 23. Subsequently, as shown in FIG. 9D, the first presser plate 25 is rotated to the horizontal position while the wrapping paper 9 is pressed with a finger. As a result, the first presser plate 25 is attracted to the first support plate 24 by the permanent magnet 30, and the old wrapping paper 9 a is sandwiched between the first support plate 24 and the first presser plate 25. At this time, the escape portion 29 formed on the first presser plate 25 prevents the finger from interfering with the first presser plate 25. Therefore, the old wrapping paper 9a can be clamped while being held down with a finger, and the old wrapping paper 9a can be accurately positioned without being displaced. Similarly, in the second stage 22, as shown in FIGS. 9 (e) and 9 (f), the leading end of the new wrapping paper 9 b is sandwiched between the second support plate 31 and the second presser plate 32.

  When the positioning of the wrapping paper 9 is completed in this way, the adhesive tape piece 41 is set on the center stage 23. In the setting of the adhesive tape piece 41, first, as shown in FIG. 4, the rotation plate 33 is rotated together with the slide plate 34 and is directed obliquely downward. From this state, the slide plate 34 is pulled out as shown in FIG. In this state, half of the adhesive tape piece 41 (first region) is guided by the first locking claw 38 and the second locking claw 40. At this time, the remaining half (second region) of the adhesive tape piece 41 maintains an extended state in which it hangs down from the tip of the slide plate 34 due to its own weight.

  When the adhesive tape piece 41 is set, the slide plate 34 is slid to the original overlapping position with respect to the rotating plate 33 as shown in FIG. 6, and the center stage 23 is moved to the horizontal position as shown in FIG. Rotate to. When the center stage 23 is rotated to the horizontal position, the adhesive surface of the first region of the adhesive tape piece 41 has the lower end surface of the old wrapping paper 9a already positioned and the lower surface of the front end portion of the new wrapping paper 9b. It sticks in contact with. Moreover, as shown in FIG. 8, the 2nd area | region of the adhesive tape piece 41 is folded in two by a crease | fold, and it adheres to the terminal part upper surface of the old wrapping paper 9a, and the front end upper surface of the new wrapping paper 9b. Thereby, the connection between the old wrapping paper 9a and the new wrapping paper 9b is completed. In this connection, since the end of the old wrapping paper 9a and the end of the new wrapping paper 9b are aligned along the alignment line, the adhesive surfaces of the adhesive tape pieces 41 to be attached are attached to each other. There is no sticking. Even if a gap is formed between the old wrapping paper 9a and the new wrapping paper 9b, the folded wrapping paper 9 is located between the adhesive tape pieces 41 and has a predetermined thickness. After all, the adhesive surfaces of the adhesive tape piece 41 do not stick to each other.

  If it connects in this way, the 1st press plate 25 and the 2nd press plate 32 will be open | released, and the packaging paper 9 will be removed from a packaging paper connection apparatus. And the wrapping paper 9 is set to a conveyance line. In this case, the old wrapping paper 9a is still inserted through the complicated conveyance path, and the connection position only needs to be positioned on the upstream side of the ink cartridge 10. For this reason, the conventional troublesome insertion operation of the wrapping paper 9 is not required, and the operation can be efficiently switched from the old wrapping paper 9a to the new wrapping paper 9b.

  According to the wrapping paper connecting device having the above-described configuration, the first stage 21 can accurately pinch the end of the old wrapping paper 9a and the second stage 22 can accurately pinch the tip of the new wrapping paper 9b. It becomes possible to connect both wrapping papers 9 accurately and straightly with the tape piece 41. Therefore, when the processing in the packaging unit 3 is resumed, the connected wrapping paper 9 is smoothly conveyed.

(1-2-2. Crimping method with long roll adhesive tape)
The wrapping paper connecting apparatus shown in FIGS. 11 and 12 is also configured to include a center stage 23 between the first stage 21 and the second stage 22 as in the case shown in FIGS. 3 to 9. Is different.

  That is, the first support plate 24 of the first stage 21 and the second support plate 31 of the second stage 22 are configured by an integral base plate 42. The base plate 42 includes a horizontal plane portion 43 and a vertical plane portion 44 that are bent into a substantially L shape. A central portion of the horizontal surface portion 43 and an upper central portion of the vertical surface portion 44 are continuously cut out, and a center stage 23 is provided at the central portion of the horizontal surface portion 43.

  The center stage 23 is provided with a first clamping plate 45 that is rotatable about a support shaft 45a, and a second clamping plate that is provided at the tip of the first clamping plate 45 so as to be rotatable about a support shaft 46a. 46. The first clamping plate 45 is positioned at a horizontal sticking position and a standby position inclined obliquely downward. The tip of the second clamping plate 46 is bent at a substantially right angle, and serves as a gripping portion 47 for gripping and operating by hand. In addition, a pair of guide pieces 46 b that project obliquely are formed at both ends of the second clamping plate 46 in order to guide both sides of the adhesive tape 49.

  A mounting plate 48 is fixed to the lower surface of the horizontal surface portion 43 of the base plate 42 and the side surface of the vertical surface portion 44 so as to be orthogonal to each other. A rotating shaft that is rotationally driven by driving means such as a motor (not shown) protrudes from the mounting plate 48, and an adhesive tape 49 wound around a roll 49a is detachably mounted thereon. In addition, a guide roller 50 is provided in the width direction on the lower surface on one end side of the horizontal surface portion 43 of the base plate 42. The guide roller 50 changes the direction of the drawn adhesive tape 49 and guides it to the first clamping surface 45 b of the first clamping plate 45.

  Reference numeral 51 denotes a cutter, which is used to cut the adhesive tape 49 so as to have an appropriate length for connecting the rear end portion of the old wrapping paper 9a and the front end portion of the new wrapping paper 9b.

  The wrapping paper connecting device having the above configuration is used as follows.

  The positioning of the old wrapping paper 9a and the new wrapping paper 9b is performed in the same manner as in the case of the folding method using the separating adhesive tape piece 41. When the positioning of the wrapping paper 9 is completed, the adhesive tape 49 is rewound from the roll 8, the direction is changed by the guide roller 50, and the second clamping plate 46 is second clamped from the first clamping surface of the first clamping plate 45. Supply to the surface. At this time, the 1st clamping plate 45 is positioned in the retraction position which goes diagonally downward centering on the spindle 45a. The adhesive tape 49 is cut into an appropriate length by the cutter 51 and placed on the first clamping surface 45b of the first clamping plate 45 and is guided by the guide piece 46b formed on the second clamping plate 46. Then, the 1st clamping plate 45 is rotated to a horizontal sticking position, and the adhesive tape 49 is stuck to the lower surface of the positioned old packaging paper 9a and the new packaging paper 9b. Subsequently, the gripping portion 47 is picked with a finger to rotate the second clamping plate 46, and the wrapping paper 9 is sandwiched between the first clamping plate 45, whereby the upper surfaces of the old wrapping paper 9a and the new wrapping paper 9b. Adhesive tape 49 is also attached. However, the cutting of the wrapping paper 9 by the cutter 51 may be performed when the wrapping paper 9 is removed from the stage after the pasting to the old wrapping paper 9a and the new wrapping paper 9b is completed.

  3 to 12, the alignment between the rear end of the old wrapping paper 9a and the front end of the new wrapping paper 9b is performed using the alignment line 37 as a mark. The end portion and the leading end portion of the new wrapping paper 9b may be set so as to overlap each other, and may be cut by cutting means such as scissors (note that the leading end of each wrapping paper 9 has been cut off) Discard the part.) According to this, it is sufficient that the old wrapping paper 9a and the new wrapping paper 9b are connected in a straight line, and it is possible to perform alignment more easily than when the alignment line 37 is used.

(1-2-3. Pinch method)
In the wrapping paper connecting device shown in FIGS. 13 to 15, the adhesive tape 49 is set in a separate clamping device 52, and the end portion of the old wrapping paper 9a and the front end portion of the new wrapping paper 9b are pre-positioned in the same manner as described above. It is intended to be attached to.

  The clamping device 52 is configured such that a tape guide 54 is provided on a base 53 and a clamping member 55 is detachable. The tape guide portion 54 is formed by forming guide protrusions 57 at predetermined intervals on the pedestal portion 56, and an adhesive tape 49 is supplied between the guide protrusions 57 and guided to the holding member 55. In addition, as shown in FIG. 10, the adhesive tape 49 used here has a strip-shaped adhesive tape piece 59 attached to a long mount 58 at a predetermined interval (here, 5 cm) so as to be peeled off. It is dedicated to the clamping device 52.

  The clamping member 55 includes a first rotation part 60 and a second rotation part 61 provided so as to be rotatable about a support shaft 60a. One end portion of a guide plate 62 formed in a substantially U shape is attached to the first rotating portion 60. The other end side of the guide plate 62 is disposed in the opening 63 formed in the second rotating portion 61. The guide plate 62 guides the adhesive tape piece 59 from the first rotation unit 60 to the second rotation unit 61.

  In the vicinity of the support shaft 60a, a peeling portion 64 for peeling the adhesive tape piece 59 from the mount 58 of the supplied adhesive tape 49 is provided. The peeling portion 64 includes a first guide piece 65 and a second guide piece 66. The first guide piece 65 is formed by curving the lower surface side, that is, the side on which the adhesive tape 49 comes into sliding contact. The adhesive tape 49 is supplied to the peeling portion 64 so that the mount 58 is positioned above, and only the mount 58 is pulled out between the guide pieces 65 and 66 for use. At this time, the mount 58 and the adhesive tape piece 59 are smoothly separated at a pointed portion (portion formed at an acute angle) of the first guide piece 65. The second guide piece 66 is provided to reliably separate the mount 58 and the adhesive tape piece 59. The adhesive tape piece 59 peeled off by the peeling portion 64 moves along the guide plate 62 and is guided in a substantially U shape along the shape of the guide plate 62. The second rotating portion 61 is formed with a misalignment prevention piece 67 located on both sides of the guide plate 62. In addition, the first rotating portion 60 is provided with a back-preventing piece 68 that prevents a back-contact by contacting the rear end of the adhesive tape piece 59 when sticking to the wrapping paper 9 as will be described later. .

  The wrapping paper connecting device having the above configuration is used as follows.

  That is, as shown in FIG. 15, the clamping member 55 is set in the clamping device 52, and the adhesive tape 49 is supplied using the tape guide portion 54. The supplied adhesive tape 49 is set by pulling out only the mount 58 from between the first guide piece 65 and the second guide piece 66 and moving the adhesive tape piece 59 to the guide plate 62. At this time, the adhesive tape piece 59 is guided by the misalignment prevention pieces 67 on both side edges. Thereby, the adhesive tape piece 59 is smoothly guided to the second rotating portion 61 through the guide plate 62 without being displaced.

  When the adhesive tape piece 59 is set on the holding member 55, as shown in FIG. 16, the end portion of the old wrapping paper 9a and the front end portion of the new wrapping paper 9b set in the same manner as in each of the above-described methods are used. It is surrounded by an adhesive tape piece 59 supported in a substantially U shape by the moving part 60 and the second rotating part 61. And as shown in FIG. 17, the packaging paper 9 is stuck from both sides by rotating the 2nd rotation part 61 with respect to the 1st rotation part 60. As shown in FIG. At this time, since the reverse prevention piece 68 contacts the rear end of the adhesive tape piece 59, the adhesive tape piece 59 does not return in the direction opposite to the insertion direction. Therefore, the adhesive tape piece 59 can be securely attached to the wrapping paper 9.

  In this way, in the wrapping paper connecting apparatus shown in FIGS. 13 to 14, the adhesive tape piece 59 can be set in a state where it can be attached in advance. Moreover, since it is only necessary to set the old wrapping paper 9a and the new wrapping paper 9b in the medicine packaging device, the configuration can be simplified.

(1-2-4. Wrapping paper insertion method (short piece))
The wrapping paper connecting device shown in FIG. 18 inserts a strip-shaped wrapping paper piece 70 with an insertion plate 69 between the old wrapping paper 9a and the new wrapping paper 9b, similar to each wrapping paper connecting device, It is made to stick by 1 heat seal member 71.

  The wrapping paper piece 70 is formed of a heat-weldable sheet that can be heat-welded only on one side as with the wrapping paper 9. When the wrapping paper piece 70 is inserted between the old wrapping paper 9a and the new wrapping paper 9b, the wrapping paper piece 70 is inserted in two so that the sticking surfaces are in contact with each other. The insertion plate 69 is formed wider than the wrapping paper piece 70, and is used to insert the wrapping paper piece 70 between the old wrapping paper 9a and the new wrapping paper 9b. However, the insertion plate 69 may be removed or kept inserted when heat-welding. The 1st heat seal member 71 forms heat seal part 15 in the tip opposite face of the support plate made to oppose so that contact and separation are possible. The first heat seal member 71 approaches and heats the old wrapping paper 9a and the new wrapping paper 9b, and heat-bonds the old wrapping paper 9a and the new wrapping paper 9b to the wrapping paper piece 70. Here, the wrapping paper piece 70 is formed to have a larger width dimension than the first heat seal member 71. This is to prevent the inner surfaces (sticking surfaces) of the wrapping paper 9 from being stuck together by heat sealing and being caught by the development guide and the hopper 14 on the downstream side in the transport direction. Moreover, since the bonding surfaces of the wrapping paper 9 are welded to each other, sufficient strength is ensured, and problems such as separation during transportation are not generated.

  In FIG. 18, the wrapping paper piece 70 is inserted between the old wrapping paper 9 a and the new wrapping paper 9 b set in advance using the insertion plate 69. It may be set and set so as to be sandwiched between the old wrapping paper 9a and the new wrapping paper 9b on both sides thereof. Further, the wrapping paper piece 70 is inserted between the old wrapping paper 9a and the new wrapping paper 9b by the insertion plate 69, but the old wrapping paper 9a and the new wrapping paper 9b may be brought closer to the wrapping paper piece 70. . In short, both may be moved relatively.

  In FIG. 18, the wrapping paper piece 70 is positioned between the old wrapping paper 9a and the new wrapping paper 9b. However, as shown in FIG. 19, the wrapping paper 9 wound around a roll (not shown) is attached. It is also possible to use rewinding and, if appropriate, separated ones. In this case, a rotating shaft for mounting the wrapping paper 9 and a cutter for cutting the wrapping paper 9 are required.

  In FIG. 18, the wrapping paper piece 70 is positioned between the old wrapping paper 9a and the new wrapping paper 9b. However, half of the wrapping paper piece 70 is heat-welded to one of the wrapping papers 9a or 9b in advance. You may leave it. According to this, it becomes possible to further simplify the connection work of the wrapping paper 9 and quickly return to the packaging work. In this case, without positioning each wrapping paper 9 by the first stage 21 or the second stage 22 as described above, the other wrapping paper 9a or 9b is pressed by a finger with the wrapping paper piece 70 heat-welded in advance. In such a state, it is possible to perform heat welding.

(1-2-5. Wrapping method for wrapping paper edge)
The wrapping paper connecting device shown in FIGS. 20 and 21 has an adhesive surface 72 on the surface by folding back one of the end portion of the old wrapping paper 9a and the front end portion of the new wrapping paper 9b (here, the new wrapping paper 9b). And a second heat seal member 73 that is heat-welded with the adhesive surface of the other wrapping paper 9 remaining on the exposed adhesive surface. When the partition plate 74 is inserted into the inner side of the wrapping paper 9 with one end folded back and heat-welded, the opposing inner surfaces (adhesion surfaces) do not adhere to each other (therefore, the partition plate 74 is 2) The width dimension is larger than that of the heat seal member 73.) In this case, it is preferable to provide positioning means for positioning the wrapping papers. In addition to the first stage 21 and the second stage 22 as described above, this positioning means may be a pin (not shown) that guides both sides of both wrapping papers 9.

  In such a wrapping paper connecting device, it is not necessary to prepare the adhesive tape 49 and the wrapping paper piece 70 separately, and the connecting operation can be performed by simply folding back one end portion of one wrapping paper 9. Further, if the existing heat seal portion 15 is used instead of the second heat seal member 73 for the heat welding, it is possible to cope with the low cost only by preparing the partition plate 74.

(1-2-6. Wrapping paper edge T-shaped bending method)
The wrapping paper connecting device shown in FIGS. 22 to 27 includes a third heat seal member 75 that thermally welds the end portion of the old wrapping paper 9a and the front end portion of the new wrapping paper 9b.

  The third heat seal member 75 includes two sets of heating portions 76a, 76b, 76c, and 76d that face each other so as to be able to contact and separate. Each of the heating parts 76a, 76b, 76c, and 76d is made of a rod having a substantially square cross section, has a built-in heating means such as a heater, and is adjusted to a predetermined temperature (however, the heating means is provided only on one of the opposing sides). For example, the heating means may be incorporated only on the fixed side of 76a and 76c, and 76b and 76d may be a contact plate). The heating parts 76a and 76b are slidably supported by the guide bar 77, respectively. The heating unit 76c is configured to move in synchronization with the heating unit 76a, and the heating unit 76d is configured to move in synchronization with the heating unit 76b. Then, by manually rotating the lever 78, the heating units 76a and 76c and the heating units 76b and 76d can be moved in synchronization to be positioned at the open position and the closed position, respectively. However, the heating units 76a, 76c and 76b, 76d may be operated not by manual operation but by driving means (not shown) (for example, a solenoid or a motor). Moreover, the heating parts 76a and 76c, 76b and 76d are each comprised so that contact / separation is possible separately. By bringing the heating parts 76a and 76c closer, the old wrapping paper 9a can be sandwiched and positioned, and by bringing the heating parts 76b and 76d closer, the new wrapping paper 9b can be positioned. Yes. The conveyance path of the wrapping paper 9 at the time of medicine packaging is below the third heat seal member 75 so as not to be affected by heat. The wrapping paper 9 is folded in the same manner as described above. Here, the wrapping paper 9 is formed by cutting a predetermined dimension (about 20 mm) from the end at the folding position.

  As described above, according to the wrapping paper connecting apparatus shown in FIGS. 22 to 27, the occupied space can be suppressed as compared with the one disclosed in the above embodiment, and the third position is close to the conveyance path of the wrapping paper 9. A seal member 75 can be disposed. Thereby, it becomes possible to suppress the loss of the wrapping paper 9 at the time of replacement (the shorter the distance between the print position on the upstream side of the conveyance path and the seal position on the downstream side where the medicine is introduced, the shorter the loss). Less.)

  The wrapping paper connecting device having the above configuration is used as follows.

  That is, the heating parts 76a, 76b, 76c, and 76d are moved to the open position by the third heat seal member 75, and the wrapping paper 9 is set. The wrapping paper 9 forms a notch from the end along the folding line, and bends it so as to be substantially T-shaped, thereby forming a sticking portion. And the termination | terminus part of the old wrapping paper 9a is arrange | positioned between a pair of upper and lower heating parts 76a and 76c located in the conveyance direction downstream of the wrapping paper 9, and it positions. In addition, the leading end of the new wrapping paper 9b is disposed between the pair of upper and lower heating portions 76b and 76d located on the upstream side in the conveyance direction of the wrapping paper 9, and is positioned by sandwiching. Thereby, each wrapping paper 9 will be in the state which made the sticking part mutually oppose. Therefore, by rotating the lever 78, the heating parts 76a and 76b, 76b and 76d are relatively brought close to each other, and the sticking surfaces of the sticking parts are brought into surface contact. Subsequently, the wrapping paper 9 is heated and thermally welded by the heating units 76a, 76b, 76c, and 76d. Thereafter, the lever 78 is rotated to the original position, and the heat-welded portion of the wrapping paper 9 is detached from the third heat seal member 75 and set to the regular conveyance path.

  When transport of the wrapping paper 9 is resumed in this state, the transport path is moved in a state where the heat-welded portion is folded along the outer surface of the wrapping paper 9. Since the wrapping paper itself is very thin, the folded portion does not become an obstacle to conveyance, and it is possible to smoothly move the complicated conveyance path and resume packaging.

  In the above-described embodiment, the case where the tablet is packaged by the medicine packaging apparatus has been described. However, as a medicine, the wrapping paper connecting apparatus having the above-described configuration can be used even if it is a powder or the like. is there.
