Detailed Description
Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following drawings, the same or corresponding portions are denoted by the same reference numerals, and description thereof will not be repeated.
Fig. 1 is a schematic configuration diagram of a packaging device 1 according to an embodiment.
The packaging apparatus 1 is used for packaging an object to be packaged. The object to be packaged is a drug, specifically, a solid drug. Examples of solid drugs include powders, granules, tablets, pills, and capsules. The object to be packaged is not limited to a solid drug. The object to be packaged may be a semisolid drug or a liquid drug.
The packaging device 1 is a medicine packaging device for packaging medicines based on prescriptions. The prescription is a prescription that is handed by a doctor to a patient. The prescription is recorded with patient information and medicine information. The patient information includes the name and age of the patient. The medicament information includes the name, dosage, usage and dosage of the medicament. In order to package 1 dose of medicament per time based on such prescription, the packaging device 1 is used.
The packaging device 1 includes a packaging material conveying unit 8. The packaging material conveying unit 8 applies a driving force to the packaging material 2 to convey the packaging material 2. The packing material 2 is in the form of a long sheet. The packaging material 2 is conveyed along the longitudinal direction of the packaging material 2. The packaging material 2 is fed from a packaging material roll 3. The packaging material roll 3 is formed by winding the packaging material 2 into a roll shape. The arrow in fig. 1 indicates the conveying direction DR of the packaging material 2. Hereinafter, the conveying direction DR of the packaging material 2 is simply referred to as "conveying direction DR". The upstream in the conveying direction DR (the side closer to the web 3 of packaging material) is referred to as "upstream". Downstream in the transport direction DR (the side remote from the web 3 of packaging material) is referred to as "downstream".
The packaging device 1 further includes a printing unit 4, a medicine supply unit 5, and a storage unit forming unit 6. The printing unit 4, the medicine supply unit 5, and the housing unit forming unit 6 are arranged in this order from the upstream to the downstream in the transport direction DR. The printing unit 4 prints predetermined information on the packaging material 2 conveyed by the packaging material conveying unit 8. The predetermined information is information associated with a medicament. The medicine supply unit 5 supplies the medicine to the packaging material 2 conveyed by the packaging material conveying unit 8. The medication is administered 1 dose at a time based on the prescription. The storage section forming section 6 forms a storage section using the packaging material 2 conveyed by the packaging material conveying section 8. The medicine is stored in the storage portion. The storage section forming section 6 forms a package in which the medicine is stored by thermally welding the packaging material 2 after the medicine is supplied from the medicine supply section 5.
The packaging device 1 further includes a tear line forming portion 7. The easy-tear line forming portion 7 is provided in the storage portion forming portion 6. The easy-tear line forming portion 7 forms an easy-tear line extending in a direction orthogonal to the conveying direction DR in the packaging material 2 conveyed by the packaging material conveying portion 8. The tear line has a plurality of fine holes arranged continuously along the short side direction of the packaging material 2.
In the packaging apparatus 1, the storage portion forming portion 6, the easy-tear line forming portion 7, and the packaging material conveying portion 8 form a packaging portion 9.
Fig. 2 is a schematic perspective view of the medicine feeder 5 and the storage unit forming unit 6 in the packaging device 1 shown in fig. 1.
At a medicine supply position where the medicine supply portion 5 supplies the medicine 100 to the packaging material 2, the packaging material 2 is folded in two along a center line in a short side direction of the packaging material 2. The both short-side edge portions 2a of the packaging material 2 are located above the central portion 2b of the packaging material 2 in the short-side direction, and the both short-side edge portions 2a are spaced apart from each other. In this way, an opening 2c facing upward is formed in the packaging material 2.
The packing material 2 may be folded in half in advance. In this case, the folded packaging material 2 is fed from the packaging material roll 3 in which the packaging material 2 folded in two in advance is wound into a roll shape.
Alternatively, the packaging material 2 may be folded in half in the middle of the conveyance path. In this case, the wrapping material 2 is wound in a roll shape without being folded in half. The packaging material 2 is fed from the thus produced packaging material roll 3. The mechanism for folding the packaging material 2 in two is provided upstream of the medicine supply position. The packaging material 2 fed from the packaging material roll 3 is folded in half at a position upstream of the medicine feeding position.
The medicine feeder 5 includes a feeder main body, not shown, and a hopper 51. The supply unit main body supplies the medicine 100. The hopper 51 guides the medicine 100 supplied from the supply unit main body to the packaging material 2. The hopper 51 has a medicine inlet 52 at its tip for introducing the medicine 100 into the packaging material 2. The medicine inlet 52 is disposed so as to enter the inside of the folded packaging material 2. The medicine 100 supplied from the supply portion main body is guided by the hopper 51, passes through the opening 2c of the packing material 2, and enters the inside of the packing material 2 folded in two.
The housing section forming section 6 includes a heating member 61, a receiving member 62, and a pressurizing motor 65. A heater 61a (see fig. 5 discussed later) is built in the heating member 61. The receiving member 62 is a member that receives the heating member 61. The heating member 61 and the receiving member 62 are disposed opposite to each other so as to sandwich the packaging material 2. The pressing motor 65 drives the heating member 61 and the receiving member 62. Heating member 61 and receiving member 62 driven by pressing motor 65 press packaging material 2 from both sides or separate packaging material 2.
The heating member 61 and the receiving member 62 are each substantially T-shaped. The heating member 61 and the receiving member 62 have a long-side direction portion 63 and a short-side direction portion 64, respectively. The longitudinal portion 63 constitutes a horizontal bar portion of a T shape, and extends in the longitudinal direction of the packaging material 2. The longitudinal direction portion 63 extends along the conveying direction DR. The short-side direction portion 64 constitutes a T-shaped longitudinal bar portion extending in the short-side direction of the packaging material 2. The short-side direction portion 64 extends in a direction orthogonal to the conveying direction DR. The longitudinal portion 63 of the heating member 61 and the longitudinal portion 63 of the receiving member 62 are disposed to face each other so as to sandwich the packaging material 2. The short-side direction portion 64 of the heating member 61 and the short-side direction portion 64 of the receiving member 62 are arranged to face each other so as to sandwich the packaging material 2.
In the housing portion forming portion 6, the heating member 61 is heated by the heater 61 a. In this state, the heating member 61 and the receiving member 62 press the packaging material 2 from both sides. In this way, the longitudinal direction heat-fusion bonded portion 23 and the short direction heat-fusion bonded portion 24 are formed on the packaging material 2. The longitudinal heat-fusion portion 23 is formed by heat-fusing a part of the packaging material 2 sandwiched between the longitudinal portion 63 of the heated member 61 and the longitudinal portion 63 of the receiving member 62. The longitudinal heat-fusion portions 23 close the opening 2c of the packaging material 2. The short-side direction heat fusion bonded portion 24 is formed by heat-fusing a part of the packaging material 2 sandwiched between the short-side direction portion 64 of the heated member 61 and the short-side direction portion 64 of the receiving member 62. The short-side direction heat fusion portions 24 divide the inside of the packaging material 2 into a downstream side and an upstream side.
Thus, the packaging material 2 is divided by the fold of the packaging material 2 folded in two, the longitudinal heat-fusion portions 23, and the two short-side heat-fusion portions 24 aligned along the conveying direction DR, to form the package 21. The short-side direction heat-fusion portions 24 form boundaries of the packages 21 adjacent in the longitudinal direction of the packaging material 2. A storage portion 22 is formed inside the package 21, and the medicine 100 is stored in the storage portion 22. The storage unit 22 stores a medicine 100 as a packaging target.
Fig. 3 is a schematic view showing a schematic configuration of the easy-tear line forming portion 7 in the packaging device 1 shown in fig. 1. Fig. 3 (a) shows the arrangement of the easy-tear line forming portion 7 when the easy-tear line 25 is not formed in the packaging material 2. Fig. 3 (B) shows the arrangement of the easy-tear line forming portion 7 when the easy-tear line 25 is formed in the packaging material 2.
As shown in fig. 3 (a), the easy-tear line forming portion 7 has an easy-tear line forming blade 71. The easy-tear line forming blade 71 is provided to the short-side direction portion 64 of the receiving member 62. The easy-tear line forming blade 71 is located at the widthwise central portion of the short-side direction portion 64 of the receiving member 62. The easy-tear line forming knife 71 extends in the short side direction of the packaging material 2. Heating member 61 is formed with a slit groove 72 in which a part of the surface facing packaging material 2 is recessed. Slit groove 72 extends in the short side direction of packaging material 2.
When the heating member 61 and the receiving member 62 press the packaging material 2 from both sides, the easy-tear-line forming knife 71 is pressed against the packaging material 2. The cutting edge of the easy-tear-line forming knife 71 protrudes from the receiving member 62 and penetrates the packaging material 2 in the thickness direction, thereby forming the easy-tear line 25 in the packaging material 2. As shown in fig. 3 (B), at this time, the cutting edge of the easy-tear line forming knife 71 moves into the slit groove 72. The tear line forming blade 71 is driven by the pressing motor 65 to move relative to the receiving member 62, similarly to the heating member 61 and the receiving member 62. The easy-tear line 25 is formed in the widthwise central portion of the short-side-direction heat-fusion bonded portion 24. Adjacent packages 21 are easily separated by cutting through wrapper 2 along tear line 25.
The easy-tear line forming blade 71 may not be provided to the receiving member 62. For example, the easy-tear line forming blade 71 disposed downstream of the storage portion forming portion 6 may form the easy-tear line 25 in the widthwise central portion of the short-side direction heat-fused portion 24 that has been formed. In this case, the easy-tear line forming portion 7 includes a driving portion for driving the easy-tear line forming blade 71 in addition to the easy-tear line forming blade 71.
Returning to fig. 2, the packaging material conveying section 8 has a pair of conveying rollers 81 and a conveying motor 82. The pair of conveying rollers 81 are disposed to face each other so as to sandwich the packaging material 2. The conveyance motor 82 rotationally drives the pair of conveyance rollers 81. The pair of conveying rollers 81 is rotationally driven by a conveying motor 82 to convey the packaging material 2.
In the wrapping unit 9 (fig. 1), the wrapping material conveying unit 8 intermittently conveys the wrapping material 2. When the conveyance of the packaging material 2 is stopped, the heating member 61 and the receiving member 62 press the packaging material 2 from both sides. At this time, the easy-tear line forming knife 71 is pressed against the packaging material 2. Thus, in the packaging material 2, the longitudinal direction heat-fusion portions 23 are formed so as to be continuous along the longitudinal direction of the packaging material 2, the short side direction heat-fusion portions 24 are formed at a constant interval along the longitudinal direction of the packaging material 2, and the easy-tear lines 25 are formed at a constant interval along the longitudinal direction of the packaging material 2. In this way, a plurality of packages 21 are formed along the longitudinal direction of packaging material 2.
The package 21 is a portion between the short-side direction heat-fusion portions 24 adjacent in the longitudinal direction of the packaging material 2 and a portion between the easy-tear lines 25 adjacent in the longitudinal direction of the packaging material 2. The short-side direction heat-fusion portions 24 serve as boundaries of the packages 21 adjacent in the longitudinal direction of the packaging material 2. The short-side direction portion 64 of the heating member 61 and the short-side direction portion 64 of the receiving member 62 function as a boundary forming portion that forms a boundary of the packaged objects 21 arranged along the conveying direction DR. The point in the conveyance direction DR where the easy-tear line forming blade 71 is disposed is referred to as a boundary forming point.
Here, the length between the widthwise central portions of the short-side direction heat-fusion portions 24 adjacent to each other in the conveying direction DR is referred to as the width W of the package 21 in the conveying direction DR. Width W represents the length between adjacent easy-tear lines 25 along the longitudinal direction of packaging material 2.
Fig. 4 is a schematic configuration diagram of the printing portion 4 in the packaging device 1 shown in fig. 1.
The printing unit 4 uses the thermal head 41 as a print head to thermally transfer the ink of the ink ribbon 45 to the wrapping material 2.
The printing section 4 has a thermal head 41 and an impression roller 44. The thermal head 41 has a plurality of heating elements. The embossing roller 44 supports the packaging material 2. The thermal head 41 and the platen roller 44 are disposed to face each other so as to sandwich the ink ribbon 45 and the packaging material 2.
The printing portion 4 also has a head contact and separation motor 42 and a head moving motor 43. The head contact and separation motor 42 reciprocates the thermal head 41 in the thickness direction (vertical direction in fig. 4) of the packaging material 2, and moves the thermal head to the pressure contact position and the separation position. The pressure contact position is a position where the thermal head 41 is pressed against the platen roller 44 via the ink ribbon 45 and the packaging material 2. The separation position is a position where the thermal head 41 is separated from the platen roller 44. A head moving motor 43 as a head moving section reciprocates the thermal head 41 and the platen roller 44 along the conveying direction DR (the left-right direction in fig. 4) of the packaging material 2. The movable range in which the thermal head 41 can move includes a printing range WA at a normal printing position and a printing range WB at a first printing position, which are discussed later.
The printing section 4 also has a tape supply shaft 46, a tape take-up shaft 47, guide rollers 48, 49, and a take-up motor 47 a. The ribbon supply shaft 46 supplies the ink ribbon 45. The ribbon take-up shaft 47 takes up the ink ribbon 45. The guide rollers 48 and 49 are provided between the tape supply shaft 46 and the tape take-up shaft 47, and guide the ink ribbon 45. The take-up motor 47a rotationally drives the tape take-up shaft 47. The ribbon take-up shaft 47 is rotationally driven by a take-up motor 47a, whereby the ink ribbon 45 is conveyed from the ribbon supply shaft 46 to the take-up shaft 47.
In the printing section 4, the thermal head 41 is moved to the pressure contact position. In this state, the thermal head is moved along the conveying path of the packaging material 2. At this time, the plurality of heating elements of the thermal head are selectively heated. Thereby, predetermined information related to the medicine 100 as the packaging object is printed on the packaging material 2.
Fig. 5 is a block diagram showing an electrical configuration of the packaging apparatus 1 according to the embodiment. As shown in fig. 5, the packaging apparatus 1 includes an operation unit 91 and an overall control unit 90.
The operation unit 91 is operated by an operator who operates the packaging apparatus 1. When the operator operates the operation unit 91, information necessary for the wrapping operation of the wrapping apparatus 1 is input to the overall control unit 90. Prescription data based on prescription and various setting information are listed as information required for the packaging operation of the packaging device 1. The setting information includes a setting interval and print contents. The width of the packages 21 is dimensioned according to the set intervals. Information necessary for the packaging operation of the packaging device 1 may be input to the overall control unit 90 from an external computer.
The overall control unit 90 controls the overall operation of the packaging apparatus 1 based on information required for the packaging operation of the packaging apparatus 1. The overall control unit 90 controls the medicine supply unit 5, the packaging unit 9, and the printing unit 4.
The overall controller 90 sends a control signal to the medicine feeder 5 to instruct the medicine feeder 5 as to the type and quantity of medicines 100 to be fed. The overall control unit 90 sends a control signal to the packing unit 9 so that the width W of the packed objects 21 in the conveying direction DR becomes a predetermined value. The width W may be a value input via the operation unit 91, or may be a value set by the overall control unit 90 based on the type and number of the medicines 100.
The packing unit 9 has a packing control unit 96. The wrapping control section 96 controls the heater 61a, the pressing motor 65, and the conveying motor 82 based on a control signal from the overall control section 90. These heater 61a, pressing motor 65, and conveying motor 82 are appropriately driven and stopped, whereby packaging of packaging material 2 is performed.
The printing unit 4 includes a printing control unit 94. The print control section 94 controls the thermal head 41, the head contact-separation motor 42, the head movement motor 43, and the take-up motor 47a based on a control signal from the overall control section 90. The heat generating elements of the thermal head 41, the head contact-separation motor 42, the head moving motor 43, and the take-up motor 47a are appropriately driven and stopped, whereby information 110 associated with the medicine 100 is printed on the packaging material 2.
Fig. 6 is a schematic diagram showing an example of printing on the packaging material 2.
A printing range 29 indicated by a two-dot chain line rectangle in fig. 6 is set in the packaging material 2. Predetermined information 110 is printed in the printing range 29. The predetermined information 110 is information related to the medicine 100 stored in the storage portion 22 of the package 21. The information 110 related to the medicine 100 includes the name, the drug name, and the usage of the patient.
The printing range 29 is set in the to-be-packaged-article forming portion 21 a. The to-be-packaged-article forming portion 21a is a portion set on the packaging material 2 and is a portion intended to constitute 1 packaged article 21. The planned packing material forming portions 21a are defined by planned boundary forming portions 25a adjacent to each other in the conveying direction DR.
The boundary forming scheduled portion 25a shown by a two-dot chain line in fig. 6 is a portion set on the packaging material 2 and is a portion scheduled to form a boundary of the packaged objects 21 adjacent in the conveying direction DR. That is, the boundary forming portion 25a is a portion intended to be a central portion in the conveying direction DR of the short-side direction heat welded portion 24 or a portion intended to form the easy-tear line 25 formed by the easy-tear line forming portion 7. The distance between the boundary-forming scheduled portions 25a adjacent to each other in the conveying direction DR corresponds to the width W of the packaged objects 21 in the conveying direction DR.
A margin is provided around the printing range 29. An upstream side margin 27 is provided on the upstream side of the printing range 29. The upstream margin 27 is a margin from the boundary forming scheduled portion 25a on the upstream side to the upstream end of the printing range 29 in the scheduled package forming portion 21 a. A downstream margin 28 is provided on the downstream side of the printing range 29. The downstream margin 28 is a margin from the boundary forming scheduled portion 25a on the downstream side to the downstream end of the printing range 29 in the scheduled package forming portion 21 a.
A width w1 shown in fig. 6 indicates a width in the conveying direction DR of the upstream side margin 27, and a width w2 indicates a width in the conveying direction DR of the downstream side margin 28. The width w1 of the upstream side margin 27 and the width w2 of the downstream side margin 28 may be the same or different.
Fig. 7 is a schematic diagram showing the arrangement of the primary printing position and the normal printing position in the conveyance direction DR. The straight lines with marks extending in the left-right direction in fig. 7 are used to indicate respective points in the conveying direction DR of the packaging material 2. The boundary forming point F shown in fig. 7 indicates a point where the storage section forming portion 6 forms a boundary between the packages 21 adjacent to each other in the conveying direction DR. As described above with reference to fig. 3, the boundary forming point F may be a point where the tear line forming blade 71 is disposed in the conveying direction DR.
A point at which a distance LA1, which is n times the width W of the packages 21 in the conveying direction DR, is separated upstream in the conveying direction DR from the boundary forming point F is the 1 st base point P1. Here, n is an integer of 1 or more. The normal printing position defines the 1 st base point P1 as the base point. More specifically, the 1 st base point P1 constitutes an upstream end in the conveyance direction DR of the normal printing position. A point at which the width W of the packages 21 in the conveying direction DR is divided downstream in the conveying direction DR from the 1 st base point P1 is the 2 nd base point P2. The 2 nd base point P2 constitutes a downstream end in the conveyance direction DR of the normal printing position. The 2 nd base point P2 is a point separated from the boundary forming point F by a distance LA2 that is (n-1) times the width W of the packaged objects 21 in the conveying direction DR upstream in the conveying direction DR. The distance between the 1 st base point P1 and the 2 nd base point P2 corresponds to the width W of the packages 21 in the conveying direction DR.
Between the distance LA1 and the width W, a relationship of LA1 — nW holds. Between the distance LA2 and the width W, a relationship of LA2 ═ n-1) W holds. Between distance LA1 and distance LA2, the relationship LA2 — LA1-W holds.
A point separated downstream in the conveyance direction DR by a width w1 of the upstream side margin 27 (fig. 6) from the 1 st base point P1 is an upstream end Pa1 of the printing range WA at the normal printing position. A point separated from the 2 nd base point P2 by the width w2 in the conveyance direction DR of the downstream side margin 28 (fig. 6) upstream in the conveyance direction DR is the downstream end Pa2 of the printing range WA at the normal printing position.
The primary printing position is a position downstream in the conveyance direction DR from the normal printing position. A point separated downstream in the conveying direction DR from the 1 st base point P1 by a distance L shorter than the width W of the packages 21 in the conveying direction DR is a3 rd base point P3. The 3 rd base point P3 constitutes an upstream end in the conveyance direction DR of the primary printing position. A point separated downstream in the conveying direction DR by the distance L from the 2 nd base point P2 is a 4 th base point P4. The 4 th base point P4 constitutes a downstream end in the conveying direction DR of the primary printing position. The distance between the 3 rd base point P3 and the 4 th base point P4 corresponds to the width W of the packaged objects 21 in the conveying direction DR.
A point separated downstream in the conveyance direction DR by a width w1 of the upstream side margin 27 (fig. 6) from the 3 rd base point P3 in the conveyance direction DR is the upstream end Pb1 of the printing range WB at the primary printing position. A point separating the width w2 of the downstream side margin 28 (fig. 6) in the conveyance direction DR from the 4 th base point P4 upstream in the conveyance direction DR is the downstream end Pb2 of the printing range WB at the primary printing position.
The printing unit 4 can perform printing at a normal printing position and a first printing position that is a position downstream of the normal printing position. The normal printing position is a range between the 1 st base point P1 and the 2 nd base point P2 in the conveyance direction DR. The primary printing position is a range between the 3 rd base point P3 and the 4 th base point P4 in the conveyance direction DR. The primary printing position is a position downstream in the conveying direction DR by a distance L shorter than the width W in the conveying direction DR of the packaged objects 21 from the normal printing position.
The predetermined limit positions are determined according to the configuration of the packaging unit 1. The extreme positions are determined as follows: the printing portion 4 interferes with the hopper 51 of the medicine feeder 5 or the like at a position downstream of the limit position in the conveying direction DR, and printing by the printing portion 4 is not performed. The limit position is a position upstream in the conveyance direction DR from the position where the storage section forming section 6 forms the storage section 22. The limit position is a position upstream in the conveying direction DR from the position where the medicine 100 is supplied by the medicine supply unit 5. The printing by the printing unit 4 can be performed at a position upstream of the limit position in the conveyance direction DR.
The primary printing position is set such that the entire printing range WB at the primary printing position is located upstream in the conveyance direction DR from the limit position. And it is desirable that the primary printing position be set as downstream in the conveying direction DR as possible. Therefore, the downstream end Pb2 of the printing range WB at the first printing position is set upstream in the conveyance direction DR from the limit position and near the limit position. Most desirably, the downstream end Pb2 of the printing range WB at the first printing position is set to the same position as the limit position. In this case, the 4 th base point P4 is located downstream of the limit position.
The printing position is usually a position upstream of the primary printing position. By setting the downstream end Pb2 of the printing range WB at the first printing position to a position upstream in the conveying direction DR from the limit position, the entire printing range WA at the normal printing position is set to a position upstream in the conveying direction DR from the limit position.
Fig. 8 is a schematic view showing a printing position when the width W in the conveying direction DR of the packaged objects 21 is changed. Similarly to fig. 7, the straight lines with marks extending in the left-right direction in fig. 8 are used to indicate respective points in the conveying direction DR of the packaging material 2. The width W in the conveying direction DR of the packaged objects 21 can be changed. By changing the width W, the capacity of the housing portion 22 can be changed. The width W is appropriately set according to the amount of the medicine 100 stored in the storage portion 22. In the example shown in fig. 8, the 1 st width W1, the 2 nd width W2, and the 3 rd width W3 are set.
The printing range WA1 at the normal printing position in the case of the 1 st width W1 is defined based on the 1 st base point of the distance LA11 from the boundary forming point F to the upstream side in the conveying direction DR, which is an integral multiple of the width W1 in the conveying direction DR of the packaged objects 21. The printing range WA2 at the normal printing position in the case of the 2 nd width W2 is defined based on the 1 st base point of the distance LA21 from the boundary forming point F to the upstream side in the conveying direction DR, which is an integral multiple of the width W2 in the conveying direction DR of the packaged objects 21. The printing range WA3 at the normal printing position in the case of the 3 rd width W3 is defined based on the 1 st base point of the distance LA31 from the boundary forming point F to the upstream side in the conveying direction DR, which is an integral multiple of the width W3 in the conveying direction DR of the packages 21.
The limit position at which printing by the printing unit 4 is not possible at the initial printing position is set as the base point regardless of the widths W1, W2, and W3 of the packages 21. As shown in fig. 8, the downstream end Pb12 of the printing range WB1 at the first printing position in the case of the 1 st width W1, the downstream end Pb22 of the printing range WB2 at the first printing position in the case of the 2 nd width W2, and the downstream end Pb32 of the printing range WB3 at the first printing position in the case of the 3 rd width W3 are set at the same position in the conveyance direction DR.
In the case of the 3 rd width W3, the printing range WA3 at the normal printing position and the printing range WB3 at the first printing position are the same position in the conveyance direction DR. In this way, the primary printing position is not necessarily a position downstream in the conveyance direction DR from the normal printing position. The primary printing position and the normal printing position may be the same position depending on the width W in the conveying direction DR of the packaged object 21.
The operation of printing the information 110 on the packaging material 2 by the printing unit 4 will be described below. Fig. 9 is a view 1 showing a printing operation by the printing section 4 when forming the package 21. In fig. 9 to 13 below, the left-right direction in the drawing indicates the conveying direction DR of the packaging material 2, the left side in the drawing indicates the upstream side in the conveying direction DR, and the right side in the drawing indicates the downstream side in the conveying direction DR. The counting numbers in the printing field 29 schematically represent the information 110 printed to the packaging material 2. When information necessary for the packaging operation is input, the packaging operation by the packaging apparatus 1 is started.
When the wrapping operation is started, as shown in fig. 9, the thermal head 41 is first moved to the downstream end Pb2 of the printing range WB at the first printing position. At this time, the thermal head 41 is maintained at the separated position. The ink ribbon 45 is not conveyed. The packaging material 2 is not conveyed. The packing material 2 is not pressed by the heating member 61 and the receiving member 62.
Fig. 10 is a view 2 showing a printing operation by the printing section 4 when forming the package 21. The thermal head 41 moved to the downstream end Pb2 of the printing range WB at the first printing position is moved from the separation position to the pressure contact position. Next, as shown in fig. 10, the thermal head 41 is moved from the downstream end Pb2 of the printing range WB at the first printing position to the upstream end Pb1 of the printing range WB at the first printing position.
At this time, the thermal head 41 is maintained at the pressure contact position. The plurality of heating elements of the thermal head 41 selectively generate heat. The ink ribbon 45 is not conveyed. The packaging material 2 is not conveyed. The packing material 2 is not pressed by the heating member 61 and the receiving member 62. In this way, the information 110 of the 1 st packet schematically indicated by the count number "1" in fig. 10 is printed on the packaging material 2 at the primary printing position. Printing is performed during the period in which the packaging material 2 is not being conveyed, thereby improving the print quality.
Fig. 11 is a view 3 showing a printing operation by the printing section 4 when forming the package 21. The thermal head 41 moved to the upstream end Pb1 of the printing range WB at the first printing position is moved from the pressure contact position to the separation position. Next, as shown in fig. 11, the thermal head 41 is moved downstream from the upstream end Pb1 of the printing range WB at the first printing position to the downstream end Pa2 of the printing range WA at the normal printing position.
At this time, the thermal head 41 is maintained at the separated position. The ink ribbon 45 is conveyed. The conveyance distance of the ink ribbon 45 corresponds to the distance between the upstream end Pb1 of the printing range WB at the first printing position and the downstream end Pa2 of the printing range WA at the normal printing position. The packaging material 2 is conveyed. The conveying distance of packaging material 2 corresponds to the distance between 3 rd base point P3 and 2 nd base point P2. That is, the conveying distance of the packing material 2 corresponds to a distance obtained by subtracting the distance L between the primary printing position and the normal printing position from the width W in the conveying direction DR of the packing material 21. The packing material 2 is not pressed by the heating member 61 and the receiving member 62.
Fig. 12 is a view 4 showing a printing operation by the printing section 4 when forming the package 21. The thermal head 41 moved to the downstream end Pa2 of the printing range WA at the normal printing position is moved from the separation position to the pressure contact position. Next, as shown in fig. 12, the thermal head 41 is moved from the downstream end Pa2 of the printing range WA at the normal printing position to the upstream end Pa1 of the printing range WA at the normal printing position.
At this time, the thermal head 41 is maintained at the crimping position. The plurality of heating elements of the thermal head 41 selectively generate heat. The ink ribbon 45 is not conveyed. The packaging material 2 is not conveyed. The packaging material 2 is pressed by the heating member 61 and the receiving member 62. In this way, the information 110 of the 2 nd package schematically indicated by the count number "2" in fig. 12 is printed on the packaging material 2 at the normal printing position. Printing and heat-welding of the packaging material 2 are performed simultaneously while the packaging material 2 is not being conveyed, thereby shortening the time required for the operation of the packaging apparatus 1.
Fig. 13 is a view 5 showing a printing operation by the printing section 4 when forming the package 21. The thermal head 41 moved to the upstream end Pa1 of the printing range WA at the normal printing position is moved from the pressure contact position to the separation position. Next, as shown in fig. 13, the thermal head 41 is moved from the upstream end Pa1 of the printing range WA at the normal printing position to the downstream end Pa2 of the printing range WA at the normal printing position.
At this time, the thermal head 41 is maintained at the separated position. The ink ribbon 45 is conveyed. The conveyance distance of the ink ribbon 45 corresponds to a distance between an upstream end Pa1 of the printing range WA at the normal printing position and a downstream end Pa2 of the printing range WA at the normal printing position. The packaging material 2 is conveyed. The conveying distance of packaging material 2 corresponds to the distance between 1 st base point P1 and 2 nd base point P2. That is, the conveying distance of the packing material 2 corresponds to the width W in the conveying direction DR of the packages 21. The packing material 2 is not pressed by the heating member 61 and the receiving member 62.
After the thermal head 41 is moved to the downstream end Pa2 of the printing range WA at the normal printing position, the operations described with reference to fig. 12 and 13 are repeated. In this way, the information 110 of the 3 rd and subsequent packages is sequentially printed on the packaging material 2 at the normal printing position.
The printed portion on which the predetermined information 110 is printed moves along the conveying direction DR as the packaging material 2 is conveyed. When the printed portion reaches the medicine supply position, the medicine 100 is supplied to the packaging material 2. In other words, the medicine 100 is not supplied to the packaging material 2 until the printed portion reaches the medicine supply position. Therefore, an empty bag is formed at a position downstream of the packing material 21 of the 1 st bag. An empty pack refers to a package 21 that does not contain a medicament 100.
The printing unit is configured to be capable of printing at a normal printing position and a first printing position downstream of the normal printing position in the conveying direction DR, and to print the information 110 of the 1 st packet at the first printing position and the information 110 of the 2 nd and subsequent packets at the normal printing position, thereby reducing empty packets. Therefore, the amount of waste of the packing material 2 can be reduced, and therefore, the amount of the packing material 2 used can be reduced.
In the above description, an example in which the packaging object packaged by the packaging device 1 is the medicine 100 is described. In the case of packaging the medicines 100 based on the prescription, the packaging material 2 is frequently wasted for each prescription, but the packaging device 1 according to the present embodiment can reduce the waste of the packaging material 2, and as a result, the waste of the packaging material 2 can be significantly reduced. The object to be packaged is not limited to the medicine 100, and may be any object.
The printing section 4 for printing the information 110 is not limited to the thermal transfer type, and may be, for example, an ink jet type.
The heating member 61 and the receiving member 62 constituting the housing portion forming portion 6 may not be T-shaped. For example, the following configuration may be adopted: the short-side direction heat-fusion part is arranged at the upstream side, the long-side direction heat-fusion part is arranged at the downstream side, the packaging object is supplied into the pre-separated accommodating part, and then the opening is heat-fused.
While the embodiments of the present invention have been described above, the embodiments disclosed herein are not intended to be limiting, but are merely illustrative in all respects. The scope of the present invention is defined by the claims, not by the above description, and is intended to include meanings equivalent to those in the claims and all modifications within the claims.
