Description

Blister sheet conveying device

Technical Field

The present invention relates to a blister sheet conveying device for conveying a blister sheet.

Background

The blister sheet comprises: a container film forming a bag portion filled with contents of tablets, capsules, and the like; and a cover film attached to the container film so as to seal the opening side of the bag portion. The blister sheet is manufactured by a blister sheet packaging machine including a bag portion forming mechanism for forming a bag portion with respect to the container film, a filling mechanism for filling the bag portion with contents, and the like.

The blister sheets are manufactured in a defined gathering device in a set of, for example, 2 blisters. Further, a predetermined number of apparatuses are provided at a time as necessary. Further, the sheet assembly in which 2 or more blister sheets are accumulated is transported to a packaging device by a blister sheet transport device and packaged. Examples of the packaging apparatus include a bundling apparatus for bundling the sheet assembly by a tape or the like, and a pillow packaging apparatus for collecting the sheet assembly and performing pillow packaging.

Further, as a blister sheet conveying device, there has been proposed a type in which a plurality of pairs of holding mechanisms are provided in a ring shape, each pair of holding mechanisms has a function of receiving and holding blister sheets supplied in parallel in 2 rows from an upstream side (for example, a gathering device side), and each pair of holding mechanisms is sequentially moved to a receiving position, a 1 st transfer position, and a 2 nd transfer position (for example, refer to patent document 1 and the like). The receiving position is a position where the holding mechanism is provided when the blister sheet is received, and the 1 st transfer position and the 2 nd transfer position are positions where the holding mechanism is provided when the blister sheet is transferred to the downstream side (packaging device side). In this apparatus, at the 1 st transfer position, the blister sheet held by one of the pair of holding mechanisms is transferred to the 1 st packaging apparatus, and at the 2 nd transfer position, the blister sheet held by the other of the pair of holding mechanisms is transferred to the 2 nd packaging apparatus.

Problems to be solved by the invention

However, in recent years, many sheet aggregates have been obtained in a short time with the improvement in productivity of blister sheet packaging machines. Thus, it is conceivable to supply the sheet aggregate to the blister sheet conveying device in a state of being juxtaposed in 4 rows instead of the past 2 rows. In this case, instead of the conventional blister sheet conveying device, it is conceivable to adopt a type in which 4 holding mechanisms corresponding to 4 rows of sheet assemblies are provided in 1 group and a plurality of groups of holding mechanisms are provided in a ring shape. In this apparatus, for example, the sheet aggregate is transferred from 2 out of 4 holding mechanisms provided at the 1 st transfer position to the 1 st packaging apparatus, and the sheet aggregate is transferred from the remaining 2 out of 4 holding mechanisms provided at the 2 nd transfer position to the 2 nd packaging apparatus.

However, in the above-described blister sheet conveying device, the rotation radius of the holding mechanism during the circular movement is large. This may lead to an increase in the size of the apparatus.

Further, since the structural part of the device such as the holding mechanism operates at a higher acceleration with an increase in the radius of rotation, it is necessary to make the driving system of the device stronger or to further improve the rigidity of the structural part. As a result, there is a risk of increasing various costs in manufacturing the device and the like. In addition, in order to more reliably hold the sheet aggregate against the centrifugal force, it is necessary to increase the holding force of the holding mechanism, but if the holding force is increased, the risk of damage to the sheet aggregate thereby increases.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a blister sheet conveying apparatus which can appropriately distribute a sheet assembly to a 1 st packaging apparatus and a 2 nd packaging apparatus and can effectively suppress an increase in size of the apparatus and an increase in manufacturing cost.

Means for solving the problems

The following describes each technical means suitable for solving the above problems in terms of items. In addition, according to needs, a special effect is added to the corresponding technical scheme.

The present invention according to claim 1 relates to a blister sheet conveying apparatus that receives a sheet aggregate from an upstream side and conveys the sheet aggregate to a downstream side where a predetermined packaging device is provided, the sheet aggregate being formed by aggregating a plurality of blister sheets each containing a content in a pocket portion, the blister sheet conveying apparatus including:

a 1 st transport mechanism in which a 1 st holding mechanism pair is provided in a plurality of ring-like forms at a predetermined interval, the 1 st holding mechanism pair has a pair of 1 st holding mechanisms capable of holding the sheet assembly, and the 1 st transport mechanism is configured to move around while sequentially moving the 1 st holding mechanism pair;

a 2 nd conveying mechanism in which a 2 nd holding mechanism pair is provided in a plurality of ring-like forms at a predetermined interval, the 2 nd holding mechanism pair has a pair of 2 nd holding mechanisms capable of holding the sheet aggregate, and the 2 nd conveying mechanism is configured to make the 2 nd holding mechanism pair move in order of position and to make the 2 nd holding mechanism pair move in a circulating manner;

the 1 st and 2 nd conveying mechanisms are arranged in parallel in an adjacent state;

the 1 st transport mechanism is configured as follows: receiving 2 rows of the sheet assembly from among the sheet assemblies supplied in parallel in 4 rows from the upstream side by the 1 st holding mechanism pair provided at a predetermined 1 st receiving position, and transferring 2 sheet assemblies held by the 1 st holding mechanism pair to a 1 st receiving port for a 1 st packaging device from the 1 st holding mechanism pair provided at a predetermined 1 st transfer position;

the 2 nd conveying mechanism is configured as follows: the sheet assembly in the remaining 2 rows of the sheet assemblies supplied in parallel in 4 rows can be received by the 2 nd holding mechanism pair provided at the 2 nd predetermined receiving position, and 2 sheet assemblies held by the 2 nd holding mechanism pair can be transferred to the 2 nd receiving port for the 2 nd packaging device from the 2 nd holding mechanism pair provided at the 2 nd predetermined transfer position.

According to

claim

1, 2 rows of the sheet assembly supplied in parallel in 4 rows can be transferred to the 1 st transfer port (the 1 st packaging device side) by the 1 st transport mechanism, and the remaining 2 rows of the sheet assembly can be transferred to the 2 nd receiving port (the 2 nd packaging device side) by the 2 nd transport mechanism. Thus, the sheet assembly can be appropriately distributed to the 1 st packaging device and the 2 nd packaging device, and the case where the required packaging capacity is high can be appropriately dealt with.

For example, the packing capacities (maximum number of packs/1 minute) of 2 packing devices were respectively 200 packs/minute, and the total packing capacity was 400 packs/minute. In this case, for example, if a sheet assembly is constituted by 2 blister sheets, and the sheet assembly is supplied to the packaging apparatus at a ratio of 400 integrated units/minute, in order to package the sheet assembly without stopping the production line, it is necessary to utilize the packaging capacity of 2 packaging apparatuses to the maximum. In this case, the 1 st and 2 nd transport mechanisms are controlled in such a manner that: the reception and handover of 2 patch aggregates were performed 100 times/1 minute respectively (i.e., the reception and handover of 200 patch aggregates/1 minute were performed). Thereby, the sheet aggregate can be appropriately distributed to the 1 st packaging device and the 2 nd packaging device.

In addition, in claim 1, since each of the 2 transport mechanisms is a type in which a pair of holding mechanisms each including a pair of holding mechanisms is annularly provided, the rotation radius of each holding mechanism during the round movement can be made smaller as compared with 1 transport mechanism in which a group of 4 holding mechanisms is annularly provided. As a result, the size of the apparatus can be effectively reduced in accordance with the case where the two conveyance mechanisms are arranged in a state of being adjacent to each other.

The present invention is the blister sheet conveying device according to claim 2, wherein the first conveying mechanism 1 is configured as follows: a pair of the 1 st holding mechanisms which can be transferred from a position between predetermined conveying mechanisms to a position where the pair of the 1 st holding mechanisms transfer 2 of the sheet assemblies held by the pair of the 1 st holding mechanisms to the 2 nd conveying mechanism;

the 2 nd conveying mechanism is configured as follows: the 2-piece aggregated body transferred from the 1 st transfer device can be received by the 2 nd holding mechanism pair provided at the transfer position between the predetermined transfer mechanisms.

According to the above-described means 2, while the sheet assembly can be appropriately distributed to 2 packaging devices, when it is not necessary to require a high packaging capacity, the sheet assembly is transferred from the 1 st transport mechanism to the 2 nd transport mechanism, and the sheet assembly is packaged only by the 2 nd packaging device. That is, according to the above-described technical means 2, the operation of dispersing the sheet assembly into 2 packaging apparatuses and the operation of collectively transporting the sheet assembly to one of the packaging apparatuses can be easily switched depending on the necessary packaging capacity. Thus, it is not necessary to always use 2 packaging devices, and the cost of packaging can be reduced.

For example, the packing capacities of 2 packing devices are respectively 200 packs/minute, and the total packing capacity is 400 packs/minute. In this case, for example, if a sheet assembly is constituted by 4 blister sheets and the sheet assembly is supplied at a rate of 200 assemblies/minute to the packaging apparatus side, the operation of packaging the sheet assembly is sufficiently performed by only one of the packaging apparatuses without stopping the production line. In this case, the 1 st transport mechanism is controlled in such a manner that: the operation of receiving the sheet assembly from the upstream side and the transfer of the received sheet assembly to the 2 nd conveying mechanism (that is, the reception and transfer of the sheet assembly of 100 pieces/1 minute) were performed at a ratio of 50 pieces/1 minute, respectively. The 2 nd transport mechanism is controlled in such a manner that: the sheet aggregate was received at a ratio of 100 pieces/1 minute from the upstream side, and the sheet aggregate was received at a ratio of 100 pieces/1 minute from the 1 st carrying mechanism, and the received sheet aggregate was transferred to the 2 nd packaging device at a ratio of 200 pieces/1 minute. Thus, the sheet aggregate can be distributed only to the 2 nd packaging device, and the packaging process using only the 2 nd packaging device can be performed.

The blister sheet conveying apparatus according to claim 3 and claim 2, wherein the mode of operation of transferring the sheet assembly from the 1 st conveying mechanism to the 2 nd conveying mechanism is configured such that: one of the 2 nd holding mechanism pairs adjacent to each other in the circulating direction receives the sheet assembly supplied from the upstream side, and the other of the 2 nd holding mechanism pairs receives the sheet assembly transferred from the 1 st conveying mechanism.

According to claim 3, the 2 nd transport mechanism is configured in such a manner that: one of the 2 nd adjacent pairs of the 2 nd holding mechanisms receives the sheet aggregate supplied from the upstream side, and the other of the 2 nd pairs of the 2 nd holding mechanisms receives the sheet aggregate forwarded from the 1 st conveying mechanism. That is, each of the 2 nd holding mechanism pairs is configured to receive the sheet aggregate from a certain object at all times. Thus, it is possible to prevent the process of transferring and receiving the sheet aggregate from being complicated more reliably, and to achieve stable operation of the apparatus.

Claim 4 relates to any one of claims 1 to 3, wherein the blister sheet conveying device includes:

a 1 st take-in conveyor capable of linearly conveying the sheet assembly forwarded to the 1 st receiving port to the 1 st packaging device;

a 2 nd take-in conveyor capable of linearly conveying the sheet assembly transferred to the 2 nd receiving port to the 2 nd packaging device by the 2 nd take-in conveyor;

the 1 st intake conveyor and the 2 nd intake conveyor are provided in parallel.

According to claim 4, the size of the apparatus can be more surely suppressed than the case where 2 intake conveyors extend in different directions.

Detailed Description

An embodiment will be described below with reference to the drawings. As shown in fig. 1 and 2, a PTP sheet 1 as a blister sheet includes a container film 3 having a plurality of bag portions 2; and a cover film 4 attached to the container film 3 so as to seal the bag portion 2.

The container film 3 is formed of a transparent or translucent thermoplastic resin material having a prescribed rigidity, of a relatively hard substance such as PP (polypropylene), PVC (polyvinyl chloride), or the like. The cover film 4 is made of a non-transparent material (e.g., aluminum foil or the like) coated on the surface with a sealant formed of, for example, a polypropylene resin or the like.

The PTP sheet 1 is substantially rectangular in plan view, and pockets consisting of 5 pocket portions 2 arranged in the sheet longitudinal direction are formed in 2 rows in the sheet width direction. Namely, the bag portions 2 totaling 10 are formed. The tablet 5 as the content is received in each pocket 21 at a time. Obviously, the number and arrangement of the pockets 2 of the PTP sheet 1 may be changed as appropriate.

The PTP sheet 1 is manufactured by a PTP packaging machine (not shown) for manufacturing the PTP sheet 1. The manufacturing process of the PTP sheet 1 includes: a bag portion forming step of forming the bag portion 2 on the container film 3, a filling step of filling the bag portion 2 with the tablet 5, an attaching step of attaching the cover film 4 on the container film 3, and the like. As shown in fig. 3, the manufactured PTP sheet 1 is collected by a collecting device 41 provided on the downstream side of the PTP packaging machine, and then sequentially conveyed to a 1 st packaging device 51 and a 2 nd packaging device 52 as packaging devices by a blister sheet conveying device 30, and packaged.

The collecting device 41 collects PTP sheets 1 sequentially conveyed from the PTP packaging mechanism on the upstream side every predetermined number of times, and supplies them to the blister sheet conveying device 30 on the downstream side. The collecting apparatus 41 of the present embodiment includes 4 rows of collecting lanes, each including: an inclusion mechanism that puts the PTP pieces 1 in a group of 2 wrapped state; and a superimposing mechanism that superimposes the PTP pieces 1 that have been packed together by a prescribed number of groups at a time.

The stacking device 41 performs a predetermined stacking operation 1 or more times to obtain a sheet assembly 7 in which a plurality of PTP sheets 1 are stacked, and then repeatedly feeds the sheet assembly 7 to the blister sheet conveying device 30 in 4 rows. The aggregation device 41 puts 2 PTP slices 1 in a packed state by the 1 st superimposing operation. Next, the aggregation device 41 superimposes the PTP slices 1 in the packed state by the superimposing operation of the 2 nd and subsequent times, and the number of superimposing operations can be appropriately set, and if the superimposing operation is set to be performed 1 time, for example, the slice aggregate 7 composed of 2 PTP slices 1 can be obtained, and if the superimposing operation is set to be performed 2, 3, 4, and 5 times, the slice aggregate 7 composed of 4, 6, 8, and 10 PTP slices 1 can be obtained.

The blister sheet transport device 30 has a function of receiving the sheet aggregate 7 from the aggregation device 41 and transporting the sheet aggregate 7 to the 1 st packaging device 51 or the 2 nd packaging device 52 on the downstream side. The structure and operation of the blister sheet conveying device 30 will be described later.

The 1 st and 2

nd packaging apparatuses

51 and 52 of the present embodiment are pillow packaging apparatuses that collect the sheet aggregate 7 and pillow-pack it, respectively. As the packaging device, a bundling device that bundles the sheet aggregate 7 with a tape or the like may be used.

The following describes the structure of the blister sheet conveying device 30.

The blister sheet conveying device 30 includes a 1 st conveying device 10 as a 1 st conveying mechanism, a 2 nd conveying device 20 as a 2 nd conveying mechanism, a 1 st intake conveyor 61, a 2 nd intake conveyor 62, and a control device 81. The 1 st conveyor 10 and the 2 nd conveyor 20 are disposed in parallel in an adjacent state.

In the present embodiment, from the aggregating device 41, of the sheet aggregates 7 supplied in 4 rows in parallel, the sheet aggregate 7 in 2 rows is supplied to the 1 st conveying device 10, and the remaining sheet aggregate 7 in 2 rows is supplied to the 2 nd conveying device 20. The amounts of the sheet aggregate 7 supplied per 1 minute to the

respective conveyors

10, 20 are the same.

First, the first conveying device 10 will be described. As shown in fig. 4 and 5, the 1 st transport device 10 includes a 1 st stage 11 (not shown in fig. 5 and the like for convenience), a 1 st holding mechanism pair 12, a 1 st holding operation mechanism 13, and a 1 st transfer mechanism 14.

The 1 st stage 11 includes 4 arm portions 11b that are rotatable about the shaft portion 11a and extend outward from the shaft portion 11a side. The arm portions 11b are provided at equal intervals in the rotation direction of the 1 st stage 11. The 1 st stage 11 is rotatable in 2 directions, and the rotation direction is controlled by the control device 81.

The 1 st holding mechanism pair 12 receives and holds the sheet aggregate 7 supplied from the aggregating device 41. The 1 st holding mechanism pair 12 is provided for every 1 st arm portion 11b, and is fixed to the 1 st stage 11 in a state of being suspended downward from the tip end portion of each arm portion 11 b. Thus, the 1 st holding mechanism pair 12 is annularly provided at equal intervals in plurality.

Each 1 st holding mechanism pair 12 has a pair of 1 st holding mechanisms 12 a. The 1 st holding mechanism 12a includes: a guide plate 12b fixed to the bottom surface of the 1 st stage 11 and extending vertically; a fixed clamping portion 12c, wherein the fixed clamping portion 12c protrudes outwards from the lower part of the guide plate 12 b; and an elevation holding portion 12d, the elevation holding portion 12d being vertically above the fixed holding portion 12c and vertically movable along the guide plate 12 b. The elevation clamp portion 12d is biased toward the fixed clamp portion 12c by a biasing mechanism (e.g., a spring member, etc.) not shown in the drawings.

The 1 st holding action mechanism 13 is movable in the up-down direction and is biased downward by a spring member or the like not shown in the drawings. The 1 st holding/operating mechanism 13 is raised to move the lifting/lowering clamp portion 12d upward, thereby opening the two

clamp portions

12c and 12 d. That is, the sheet aggregate 7 is in a state of being receivable (see fig. 6). Note that, in fig. 6 and 8, for convenience of illustration, the 1 st holding mechanism pair 12 provided at the intermediate position P13 described later is not illustrated). Further, if the sheet aggregate 7 is thrown between the two

grippers

12c, 12d in this state from the aggregating device 41 side, the 1 st holding operation mechanism 13 moves downward, and thereby the elevation gripper 12d moves downward by the biasing force of the biasing mechanism. As a result, the sheet assembly 7 is held in a sandwiched state by the two sandwiching

portions

12c and 12 d.

The 1 st transfer mechanism 14 moves from the rotation center side of the 1 st stage 11 toward the outside, and wipes both sides of the fixed nip portion 12c and the lifting nip portion 12d, thereby pressing the sheet assembly 7 held by the both nip

portions

12c and 12d to the outside (see fig. 6).

The 1 st holding mechanism pair 12 performs a circulating motion while sequentially moving the positions in accordance with the rotation of the 1 st stage 11. Specifically, the 1 st holding mechanism pair 12 rotates intermittently in sequence at the 1 st receiving position P11, the 1 st transfer position P12, the intermediate position P13, and the inter-conveying-mechanism receiving position P14 (see fig. 7). These positions P11, P12, P13, P14 are equally spaced in the rotation direction of the 1 st stage 11.

The 1 st receiving position P11 is a position to receive from the side of the aggregation device 41 and hold the sheet aggregate 7 of row 2. The 1 st holding operation mechanism 13 is provided corresponding to the 1 st receiving position P11, and the 1 st holding operation mechanism 13 is operated, whereby the 1 st holding mechanism pair 12 provided at the 1 st receiving position P11 receives and holds the 2 sheet assemblies 7.

The 1 st transfer position P12 is a position at which the sheet assembly 7 held by the 1 st holding mechanism pair 12 is transferred to a 1 st receiving port 61r, described later, of the 1 st intake conveyor 61. The 1 st transfer mechanism 14 is provided corresponding to the 1 st transfer position P12, and by the operation of the 1 st transfer mechanism 14, the sheet aggregate 7 is transferred from the 1 st holding mechanism pair 12 located at the 1 st transfer position P12 to the 1 st receiving port 61 r.

The inter-conveying-mechanism transfer position P14 is a position at which the sheet aggregate 7 held by the 1 st holding mechanism pair 12 is transferred to the 2 nd conveying device 20. The 1 st transfer mechanism 14 is provided corresponding to the inter-conveying-mechanism transfer position P14, and by the operation of the 1

st transfer mechanism

14, 2 pieces of the aggregated sheet 7 are pushed out from the 1 st holding mechanism pair 12 located at the inter-conveying-mechanism transfer position P14 to the 2 nd conveying device 20 side and transferred to the 2 nd conveying device 20 (see fig. 8).

In the present embodiment, when the blister sheet conveying device 30 is operated in a distributed conveying mode described later, the 1 st conveying mechanism 14 located at the 1 st transfer position P12 is operated, while the 1 st conveying mechanism 14 located at the inter-conveying-mechanism transfer position P14 is not operated. In contrast, when the blister sheet conveying device 30 is operated in the centralized conveying method described later, the 1 st conveying mechanism 14 located at the 1 st transfer position P12 is not operated, and the 1 st conveying mechanism 14 located at the inter-conveying-mechanism transfer position P14 is operated.

The following describes the 2 nd conveyance device 20. As shown in fig. 4 and 9, the 2 nd transport device 20 includes a 2 nd table 21 (not shown in fig. 9 and the like), a 2 nd holding mechanism sub 22, a 2 nd holding operation mechanism 23, and a 2 nd transfer mechanism 24.

The 2 nd stage 21 includes 4 arm portions 21b which are rotatable about the shaft portion 21a and extend outward from the shaft portion 21a side. The arm portions 21b are provided at equal intervals in the rotation direction of the 2 nd stage 21.

The 2 nd holding mechanism pair 22 receives and holds the sheet aggregate 7 supplied from the aggregating device 41 or the 1 st conveying device 10. The 2 nd holding mechanism pair 22 is provided 1 at a time with respect to the 2 nd arm portion 21b, and is provided in a plurality of ring-like shapes at equal intervals. The 2 nd holding mechanism pair 22 has a pair of 2 nd holding mechanisms 22a, respectively.

The 2 nd holding mechanism 22a has the same structure as the 1 st holding mechanism 12a, and includes a guide plate 22b, a fixing clamp 22c, and an elevation clamp 22 d. The elevation clamp portion 22d is in a state of being biased to the fixed clamp portion 22c side by a biasing mechanism (e.g., a spring member or the like) not shown in the drawings.

The 2 nd holding/operating mechanism 23 has the same configuration as the 1 st holding/operating mechanism 13, and moves the lifting/lowering nip portion 22d upward, thereby bringing the sheet assembly 7 into a state in which it can be received between the two nip

portions

22c, 22d (see fig. 10. in fig. 10, 12, the 2 nd holding mechanism pair 22 provided at an intermediate position P23 described later is not shown for convenience of illustration). Further, if the sheet assembly 7 is thrown between the two

grippers

22c, 22d in this state, the 2 nd holding operation mechanism 23 moves downward, and thereby the elevation gripper 22d moves downward by the biasing force of the biasing mechanism. As a result, the sheet assembly 7 is held in a sandwiched state by the two sandwiching

portions

22c and 22 d.

The 2 nd transfer mechanism 24 has the same configuration as the 1 st transfer mechanism 14, and has a function of pressing the sheet aggregate 7 held by the 2 nd holding mechanism pair 22 to the outside by moving from the shaft portion 21a side to the outside (see fig. 10).

The 2 nd holding mechanism pair 22 performs a circulating motion while sequentially moving the positions in accordance with the rotation of the 2 nd stage 21. Specifically, the 2 nd holding mechanism pair 22 rotates intermittently in sequence at the 2 nd receiving position P21, the 2 nd transfer position P22, the intermediate position P23, and the inter-conveying-mechanism receiving position P24 (see fig. 11). These positions P21, P22, P23, P24 are equally spaced in the rotation direction of the 2 nd stage 21.

The 2 nd receiving position P21 is a position to receive and hold the remaining sheet aggregate 7 in the 2 rows among the sheet aggregates 7 fed in parallel in the 4 rows from the aggregation device 41. The 2 nd holding operation mechanism 23 is provided at the 2 nd receiving position P21, and the 2 nd holding mechanism pair 22 provided at the 2 nd receiving position P21 receives and holds the 2 nd aggregation of sheets 7 by the operation of the 2 nd holding operation mechanism 23.

The 2 nd transfer position P22 is a position at which the sheet assembly 7 held by the 2 nd holding mechanism pair 22 is transferred to a 2 nd receiving port 62r, which will be described later, of the 2 nd intake conveyor 62. The 2 nd transfer mechanism 24 is provided corresponding to the 2 nd transfer position P22, and the 2 nd transfer mechanism 24 operates to transfer the 2 nd aggregated piece 7 from the 2 nd holding mechanism pair 22 located at the 2 nd transfer position P22 to the 2 nd receiving port 62 r.

The inter-conveyor-mechanism receiving position P24 is a position at which the sheet aggregate 7 is received from the 1 st conveyor 10. By providing the 2 nd holding operation mechanism 23 at the inter-conveying-mechanism receiving position P24 and operating the 2 nd holding operation mechanism 23, the 2 nd holding mechanism pair 22 can receive the 2 piece aggregation bodies 7, and the 2 piece aggregation bodies 7 are handed over from the 1 st holding mechanism pair 12 located at the inter-conveying-mechanism receiving position P14 (see fig. 12).

Next, referring back to fig. 3, the 1 st intake conveyor 61 and the 2 nd intake conveyor 62 will be described.

The 1 st intake conveyor 61 linearly conveys the sheet aggregate 7 received from the 1 st conveying device 10 to the 1 st packing device 51. The 1 st intake conveyor 61 includes a 1 st receiving port 61r provided adjacent to the 1 st transfer position P12, and can receive 2 sheet assemblies 7 at a time at the 1 st receiving port 61 r.

The 2 nd intake conveyor 62 linearly conveys the sheet aggregate 7 received from the 2 nd conveying device 20 to the 2 nd packaging device 52. The 2 nd intake conveyor 62 includes a 2 nd receiving port 62r provided adjacent to the 2 nd transfer position P22, and can receive 2 sheet assemblies 7 at a time at the 2 nd receiving port 62 r.

The 1 st intake conveyor 61 and the 2 nd intake conveyor 62 are provided in parallel.

The 1 st intake conveyor 61 and the 2 nd intake conveyor 62 may be constituted by a conveying device having, for example, a conveying base (not shown in the drawings) for loading the sheet aggregate 7, and a support pin (not shown in the drawings) projecting from an upper surface of the conveying base and conveying the sheet aggregate 7 to the

packaging devices

51 and 52 while hooking the sheet aggregate 7.

The control device 81 will be explained below. The control device 81 includes: a CPU as an arithmetic means, a ROM for storing various programs, a RAM for temporarily storing various data such as arithmetic data and input/output data, and a hard disk for storing arithmetic data for a long period of time.

The control device 81 controls the operation of the blister sheet conveying device 30 so that the blister sheet conveying device 30 operates in a manner of uniformly distributing the sheet aggregate 7 supplied from the aggregating device 41 to the 2 packaging devices 51, 52 (distributed conveying manner) or conveying the sheet aggregate 7 only to the 2 nd packaging device 52 (centralized conveying manner). Next, the operation of the control device 81 when the blister sheet conveying device 30 is operated by the distributed conveying method and the operation of the control device 81 when the blister sheet conveying device 30 is operated by the collective conveying method will be described in detail as 1.

First, a case where the blister sheet conveying device 30 is operated in the distributed conveying system will be described. In this case, the controller 81 sets the rotation direction of each of the

stations

11 and 21 on the shortest route from the reception positions P11 and P21 to the transfer positions P12 and P22. In the case of the present embodiment, the rotation direction of the 1 st stage 11 is set to the clockwise rotation direction, and the rotation direction of the 2 nd stage 21 is set to the counterclockwise rotation direction.

The control device 81 controls the respective tables 11 and 21 in such a manner that: the number of intermittent rotational movements (number of positional movements) of the holding mechanism pairs 12 and 22 per 1 minute is the same as half of the amount of supply per 1 minute from the accumulating device 41 to the sheet aggregate 7 of the respective conveying

devices

10 and 20.

For example, 800 PTP sheets 1 are manufactured every 1 minute by the PTP packaging machine described above, and these PTP sheets 1 are fed to the accumulation device 41. Here, if the sheet aggregate 7 is composed of 2 PTP sheets 1, 400 sheet aggregates 7 are supplied to the blister sheet conveying device 30 every 1 minute, and 200 sheet aggregates 7 are supplied to the conveying

devices

10, 20 every 1 minute. In this case, the control device 81 controls the respective conveying

devices

10 and 20 so that the rotational movement of the holding mechanism pairs 12 and 22 is intermittently performed 100 times every 1 minute. That is, the operations of the

respective conveyors

10 and 20 are controlled so that the receiving operation of the sheet aggregate 7 is performed every 1 minute and every 100 times, and 200 sheet aggregates 7 are received every 1 minute. The movement time of each of the holding mechanism pairs 12 and 22 when moving between the respective positions P11 to P14 and P21 to P24 and the temporary stop time of each of the holding mechanism pairs 12 and 22 at the respective positions P11 to P14 and P21 to P24 are appropriately set in accordance with the supply amount of the sheet aggregate 7 from the aggregating device 41 to the blister sheet conveying device 30, and the like.

Further, the control device 81 causes the 1 st and 2 nd holding/

operating mechanisms

13, 23 provided at the receiving positions P11, P21 to operate upward at the time when the respective holding mechanism pairs 12, 22 are temporarily stopped, and causes the 1 st and 2 nd holding/

operating mechanisms

13, 23 to move downward at the time immediately after the sheet aggregate 7 is supplied from the aggregation device 41. Thus, the sheet assembly 7 supplied from the assembly device 41 is sequentially held by the holding mechanism pairs 12 and 22 provided at the receiving positions P11 and P21. The 2 nd holding operation mechanism 23 provided at the receiving position P24 between the conveyance mechanisms is controlled so as not to operate.

For example, as shown in fig. 13, in the case where the sheet aggregate 7 is composed of 2 PTP sheets 1, the sheet aggregate 7 is supplied to each of the

conveyors

10, 20 every 1 time the stacking operation is performed in the aggregating device 41, but the supplied sheet aggregate 7 is sequentially held by the holding mechanism pairs 12, 22 provided at the receiving positions P11, P21.

Fig. 13 to 16 are explanatory diagrams including timing charts showing the superimposing operation by the accumulating device 41 or the operations (movement and temporary stop) of the 2 holding mechanism pairs 12 and 22, and state diagrams schematically showing states of the 2 conveying

devices

10 and 20. In fig. 13 to 16, the case where the sheet aggregate 7 is supplied from the aggregating device 41 to the conveying

devices

10 and 20 is shown by broken-line arrows. In the state diagram schematically showing the states of the 2 conveying

devices

10 and 20, the receiving and forwarding of the sheet aggregate 7 are shown by solid arrows. In the state diagram, black circles, black rectangles, blank circles, and blank arrows are shown corresponding to the respective holding mechanism pairs 12 and 22, so that the states of the 2

transport devices

10 and 20 can be grasped more easily. In each drawing, the time t required for the superimposing operation is always constant.

Further, the controller 81 operates the 1 st transfer mechanism 14 and the 2 nd transfer mechanism 24 provided at the transfer positions P12 and P22 from the

shaft portions

11a and 21a side to the outside at the time when the holding mechanism pairs 12 and 22 are temporarily stopped. Thereby, the 2 sheet assemblies 7 held by the holding mechanism pairs 12 and 22 located at the transfer positions P12 and P22 are pushed toward the

intake conveyors

61 and 62, respectively, and transferred to the receiving

ports

61r and 62 r. The 1 st transfer mechanism 14 provided at the inter-conveyor transfer position P14 is controlled to be non-operative.

By controlling the blister sheet conveying device 30 as described above, each time the holding mechanism pairs 12 and 22 move positions, the sheet aggregate 7 is received by the aggregation device 41 and the sheet aggregate 7 is transferred to the 2 receiving

ports

61r and 62 r. As a result, the sheet aggregate 7 supplied to the blister sheet conveying device 30 is equally distributed to the

packaging devices

51, 52 by the 2 conveying

devices

10, 20.

Next, the case where the blister sheet conveying device 30 is operated by the collective conveying method will be described. In this case, the rotation direction of the 1 st stage 11 is set to the direction of the route from the 1 st receiving position P11 to the shortest receiving position P14 between the transport mechanisms. On the other hand, the rotation direction of the 2 nd stage 21 is set in the same manner as the rotation direction of the distributed conveyance system. As a result, in the present embodiment, the rotation directions of the 2 tables 11 and 21 are set to be the counterclockwise rotation directions, respectively.

Next, the controller 81 controls the 2 nd conveying device 20 so that the number of intermittent rotational movements (number of positional movements) of the 2 nd holding mechanism pair 22 per 1 minute is equal to the number of supply of the sheet aggregate 7 per minute from the aggregating device 41 to each of the conveying

devices

10 and 20.

For example, when 100 pieces of the aggregated sheets 7 are supplied to the respective conveying

devices

10 and 20 per minute, the second conveying device 20 is controlled as follows: the rotational movement of the 2 nd holding mechanism pair 22 is intermittently performed 100 times per minute. The movement time of the 2 nd holding mechanism pair 22 when moving between the respective positions P21 to P24 and the temporary stop time of the 2 nd holding mechanism pair 22 at the respective positions P21 to P24 are appropriately set in accordance with the supply amount of the sheet aggregate 7 from the aggregating device 41 to the blister sheet conveying device 30, and the like.

On the other hand, the control device 81 controls the 1 st transport device 10 in such a manner that: the number of intermittent turning movements (number of positional movements) of the 1 st holding mechanism pair 12 per 1 minute is the same as half the number of sheet aggregate 7 fed per minute to each of the

conveyors

10, 20.

For example, when 100 pieces of the sheet aggregate 7 are supplied to the respective conveying

devices

10 and 20 per minute, the 1 st conveying device 10 is controlled so that the turning motion of the 1 st holding mechanism pair 12 is intermittently performed 50 times every 1 minute. Thus, while the 1 st holding mechanism pair 12 is temporarily stopped and moved 1 time, the 2 nd holding mechanism pair 22 is temporarily stopped and moved 2 times. While the 1 st holding mechanism pair 12 is temporarily stopped, the movement and the timing of the temporary stop of the 2 nd

holding mechanism pair

12, 22 are controlled so that the 2 nd holding mechanism pair 22 is temporarily stopped 2 times.

Further, the control device 81 operates the 1 st holding operation mechanism 13 provided at the 1 st receiving position P11 at the time when the 1 st holding mechanism pair 12 is temporarily stopped. On the other hand, the controller 81 causes the 2 nd holding operation mechanism 23 provided at the 2 nd receiving position P21 to perform 1 operation each time the 2 nd holding mechanism pair 22 is temporarily stopped 2 times. Thus, the sheet aggregate 7 fed from the aggregating device 41 is sequentially held by the holding mechanism pairs 12, 22 moved to the receiving positions P11, P21, but the 2 nd holding mechanism pair 22 holds the sheet aggregate 7 fed from the aggregating device 41 by 1 time of reception during 2 times of rotational movement. As a result, only one of the pair of 2 nd holding mechanism pairs 22 adjacent in the direction of the cyclic movement receives from the aggregation device 41 and holds the sheet aggregate 7.

For example, as shown in fig. 14 to 16, when the sheet aggregate 7 is composed of 4, 6, or 10 PTP sheets 1, the stacking operation is performed 2 times, 3 times, or 5 times in the stacking apparatus 41, and then the sheet aggregate 7 is supplied to the respective conveying

apparatuses

10, 20. At this time, the 1 st holding mechanism pair 12 provided at the 1 st receiving position P11 sequentially holds the supplied sheet assembly 7. On the other hand, the 2 nd holding mechanism pair 22 provided at the 2 nd receiving position P21 holds the fed sheet aggregate 7 every 1. Fig. 14 shows a case where the number of PTP pieces 1 constituting the piece aggregate 7 is 4, fig. 15 shows a case where the number of PTP pieces 1 constituting the piece aggregate 7 is 6, and fig. 16 shows a case where the number of PTP pieces 1 constituting the piece aggregate 7 is 10.

The controller 81 operates the 2 nd holding operation mechanism 23 provided at the inter-conveyor receiving position P24 at a predetermined timing (in the present embodiment, substantially the same timing as the operation timing of the 2 nd holding operation mechanism 23 provided at the 2 nd receiving position P21) when the 1 st holding mechanism pair 12 is temporarily stopped. Thus, the 2 nd holding mechanism pair 22 provided at the inter-conveying-mechanism receiving position P24 can receive the sheet aggregate 7 from the 1 st conveying device 10 and hold it.

The control device 81 controls the 1 st transfer mechanism 14 so that the 1 st transfer mechanism 14 provided at the 1 st handover position P12 does not operate. Thereby, the sheet aggregate 7 is not transferred from the 1 st transport device 10 to the 1 st receiving port 61 r.

On the other hand, when the respective 2 holding mechanism pairs 12 and 22 are temporarily stopped, the controller 81 operates the 1 st transfer mechanism 14 provided at the inter-conveyor-mechanism transfer position P14 at substantially the same timing as when the 2 nd holding/operating mechanism 23 provided at the inter-conveyor-mechanism receiving position P24 is operated. Thereby, the sheet aggregate 7 is transferred from the 1 st conveying device 10 to the 2 nd conveying device 20, and the sheet aggregate 7 transferred by the 2 nd holding mechanism pair 22 provided at the inter-conveying-mechanism receiving position P24 is held.

Further, the 2 nd holding mechanism pair 22 that receives the sheet aggregate 7 from the 1 st transport device 10 is different from the pair of 2 nd holding mechanism pairs 22 adjacent in the circulating direction, and one of the sheet aggregates 7 is received from the aggregation device 41. As described above, in the present embodiment, one of the 2 nd holding mechanism pairs 22 adjacent to each other in the circulating direction receives the sheet aggregate 7 supplied from the aggregation device 41, and the other of the 2 nd holding mechanism pairs 22 receives the sheet aggregate 7 transferred from the 1 st transport device 10. For example, in the example shown in fig. 14 to 16, the 2 nd holding mechanism pair 22 corresponding to the black circle and the blank circle receives the sheet aggregate 7 supplied from the aggregation device 41, and the 2 nd holding mechanism pair 22 corresponding to the black rectangle and the blank rectangle receives the sheet aggregate 7 transferred from the 1 st transport device 10.

Further, the control device 81 operates the 2 nd transfer mechanism 24 provided at the 2 nd transfer position P22 at the time when the 2 nd holding mechanism pair 22 is temporarily stopped. Thereby, the 2 sheet assemblies 7 held by the 2 nd holding mechanism pair 22 are pushed toward the 2 nd intake conveyor 62 and transferred to the 2 nd receiving port 62 r. As a result, the sheet aggregate 7 directly supplied from the aggregation device 41 and the sheet aggregate 7 received from the 1 st transport device 10 are alternately transferred to the 2 nd receiving port 62 r.

By controlling the operation of the blister sheet conveying device 30 in this manner, the sheet aggregate 7 supplied from the accumulating device 41 to the 2 conveying

devices

10 and 20 is conveyed only to the 2 nd packaging device 52 without being conveyed to the 1 st packaging device 51 side.

As described above in detail, according to the present embodiment, in the case of the distributed conveyance system, 2 rows of the sheet aggregate 7 supplied in parallel in 4 rows can be transferred to the 1 st transfer port 61r (the 1 st packaging device 51 side) by the 1 st conveying device 10, and the remaining 2 rows of the sheet aggregate 7 can be transferred to the 2 nd receiving port 62r (the 2 nd packaging device 52 side) by the 2 nd conveying device 20. This makes it possible to appropriately distribute the sheet assembly 7 to the 1 st packaging device 51 and the 2 nd packaging device 52, and appropriately cope with cases where the required packaging capacity is high.

On the other hand, when it is not necessary to require a packaging capacity as high, the blister sheet transport device 30 is operated in a collective transport system to transfer the sheet assembly 7 from the 1 st transport device 10 to the 2 nd transport device 20, whereby the sheet assembly 7 can be packaged only by the 2 nd packaging device 52.

As described above, in the case of the present embodiment, the mode (the distributed conveying mode) of dispersing the sheet assembly to the side of the 2

packaging devices

51, 52 can be easily switched depending on the necessary packaging capacity; the sheet aggregate 7 is collectively conveyed to the 2 nd packaging device 52 side (collective conveyance method). Thus, it is not necessary to use 2

packing devices

51 and 52, and the cost of packing can be reduced.

In addition, since the holding mechanism pairs 12 and 22 each including the pair of holding

mechanisms

12a and 22a are provided in the form of a ring in the 2

transport devices

10 and 20, the turning radius of the holding

mechanisms

12a and 22a during the round movement can be made smaller than that of a transport mechanism in which a group including 4 holding mechanisms is provided in the form of a ring. As a result, the size increase of the blister sheet conveying device 30 can be effectively suppressed in accordance with the case where 2 conveying

devices

10 and 20 are arranged in parallel in an adjacent state.

Further, since the radius of rotation of the holding

mechanisms

12a and 22a can be made smaller, the holding

mechanisms

12a and 22a, and the components of the blister sheet conveying device 30 such as the tables 11 and 21 operate at a small acceleration. Accordingly, it is not necessary to make the driving system of the blister sheet conveying device 30 more robust or to make the structural parts more rigid so as to cope with an increase in acceleration, and it is possible to effectively suppress an increase in various costs such as manufacturing the device. Further, at the time of the turning motion of the holding

mechanisms

12a, 22a, since the centrifugal force applied to the sheet aggregate 7 is small, it is not necessary to increase the holding force of the holding

mechanisms

12a, 22 a. Thus, damage to the sheet aggregate 7 accompanying an increase in holding force can be more reliably prevented.

When the blister sheet conveying device 30 is operated in the collective conveying manner, in the 2 nd conveying device 20, one of the 2 nd holding mechanism pairs 22 adjacent thereto receives the sheet collective body 7 supplied from the aggregating device 41, and the other of the 2 nd holding mechanism pairs 22 receives the sheet collective body 7 transferred from the 1 st conveying device 10. That is, each of the 2 nd holding mechanism pairs 22 often receives the sheet aggregate 7 from a certain object. Thus, it is possible to prevent the process of transferring and receiving the sheet assembly 7 from being complicated more reliably, and to achieve stable operation of the blister sheet conveying device 30.

Further, since the 1 st intake conveyor 61 and the 2 nd intake conveyor 62 are provided in parallel, the size increase of the blister sheet conveying device 30 can be more reliably suppressed as compared with the case where the 2

intake conveyors

61, 62 extend in different directions.

The present invention is not limited to the description of the above embodiments, and may be implemented as follows, for example. Obviously, other application examples and modification examples not listed below are of course possible.

(a) In the above embodiment, the blister sheet conveying device 30 is configured as follows: the sheet aggregate 7 is conveyed (centralized conveyance system) only to the 2 nd packaging device 52 so as to distribute the sheet aggregate 7 uniformly to the 2 packaging devices 51 and 52 (uniform conveyance system). In contrast, the blister sheet conveying device 30 may be operated so as to distribute the sheet assembly 7 unequally to the 2 packaging devices 51 and 52 (unequal conveyance system).

For example, the 1 st transport device 10 is configured as follows: half of the sheet assembly 7 supplied from the assembling device 41 is transferred to the 1 st receiving port 61r (the 1 st packaging device 51 side), and the remaining half is transferred to the 2 nd conveying device 20, and the 2 nd conveying device 20 is configured as follows: the sheet aggregate 7 received from the aggregating device 41 and the 1 st conveying device 10 is entirely transferred to the 2 nd receiving port 62r (the 2 nd packaging device 52 side). In this case, 1/4 in the sheet aggregate 7 supplied from the aggregating device 41 to the blister sheet conveying device 30 can be conveyed to the 1

st packaging device

51, and 3/4 in the supplied sheet aggregate 7 can be conveyed to the 2 nd packaging device 52. Obviously, the ratio of the number of sheet aggregates 7 conveyed to each of the

packing devices

51, 52 can be changed by adjusting the number of passes of the sheet aggregate 7 from the 1 st conveyor 10 to the 2 nd conveyor 20.

The packaging machine can be configured in this manner, and can cope with the case where the number of packages in the 1 st packaging device 51 is different from the number of packages in the 2 nd packaging device 52. For example, when the bundling apparatus is used as the 1 st packaging apparatus 5 and the pillow packaging apparatus is used as the 2 nd packaging apparatus 52, the number of the sheet assemblies 7 bundled by the tape and the number of the sheet assemblies 7 to be pillow-packaged can be different.

(b) The number of the holding mechanism pairs 12 and 22 of the above embodiment is exemplary, and the number of the holding mechanism pairs 12 and 22 may be changed as appropriate. Accordingly, each of the

transport devices

10 and 20 may have 6 or 8 holding mechanism pairs 12 and 22, respectively. Obviously, the number of the holding mechanism pairs 12 and 22 may be an odd number, or the number of the 1 st holding mechanism pair 12 and the number of the 2 nd holding mechanism pair 22 may be different.

(c) In the case of the above embodiment, the PTP sheet 1 is exemplified as the blister sheet, but the technical idea of the present invention can be applied to blister sheets other than the PTP sheet 1. In the case of the above embodiment, the tablet 5 is exemplified as the content, but the content may be a capsule, an electronic device, or the like.
