  By the way, in recent years, with the improvement of the productivity of blister packaging machines, many sheet assemblies have been obtained in a short time. In view of this, it is conceivable to supply the sheet stack to the blister sheet conveying apparatus in a state of being arranged in four rows instead of the conventional two rows. In this case, instead of the above-described conventional blister sheet conveying device, a set of four holding means corresponding to four rows of sheet stacks and a plurality of holding means arranged annularly is used. It is possible. In this apparatus, for example, the sheet stack is delivered from two of the four holding means arranged at the first delivery position to the first packaging apparatus side, and the four sheets arranged at the second delivery position are transferred. The sheet assembly is delivered from the remaining two of the holding means to the second packaging device side.

  However, in the blister sheet conveying apparatus as described above, the turning radius when the holding means makes a circular movement becomes relatively large. Therefore, there exists a possibility of causing the enlargement of an apparatus.

  Further, as the turning radius increases, the components of the device such as the holding means operate with a larger acceleration, so that it is necessary to make the drive system of the device stronger and to increase the rigidity of the components. . As a result, there is a risk of increasing various costs related to the manufacture of the device. Furthermore, in order to hold the sheet assembly more securely against the centrifugal force, it is necessary to increase the holding force in the holding means. However, if the holding force is increased, the sheet stack is increased by that amount. The risk of damaging will increase.

  The present invention has been made in view of the above circumstances, and the object thereof is to appropriately distribute sheet aggregates arranged in four rows to the first packaging device and the second packaging device. An object of the present invention is to provide a blister sheet conveying apparatus capable of effectively suppressing an increase in size and manufacturing cost of the apparatus.

  In the following, each means suitable for solving the above-described object will be described in terms of items. In addition, the effect specific to the means to respond | corresponds as needed is added.

Means 1. A blister sheet conveying apparatus that receives a sheet aggregate formed by accumulating a plurality of blister sheets containing contents in a pocket portion from the upstream side, and conveys the sheet assembly to the downstream side where a predetermined packaging device is disposed,
A plurality of first holding pairs each including a pair of first holding means capable of holding the sheet stack are arranged in a ring shape at a predetermined interval, and the first holding pairs are circulated while sequentially moving their positions. First conveying means configured to:
A plurality of second holding pairs each having a pair of second holding means capable of holding the sheet stack are arranged in a ring shape at predetermined intervals, and the second holding pairs are circulated while sequentially moving their positions. A second conveying means configured in
The first conveying means and the second conveying means are arranged side by side in an adjacent state,
The first conveying means is configured to store the sheet stacks for two rows among the sheet stacks supplied in a row from the upstream side by the first holding pair arranged at a predetermined first receiving position. Receive and deliver the two sheet stacks held in the first holding pair from the first holding pair arranged at a predetermined first delivery position to the first receiving port for the first packaging device Composed of
The second transport means receives the sheet stack for the remaining two rows of the sheet stack supplied from the second holding pairs arranged at a predetermined second receiving position in four rows, The two sheet stacks held in the second holding pair can be transferred from the second holding pair arranged at a predetermined second delivery position to the second receiving port for the second packaging device. A blister sheet conveying apparatus, wherein

  According to the means 1, the first conveying means can deliver two rows of the sheet stacks supplied in a row to the first receiving port (first packaging device side), By the second conveying means, the remaining two rows of sheet aggregates can be delivered to the second receiving port (second packaging device side). Thereby, a sheet | seat assembly can be appropriately distributed with respect to a 1st packaging apparatus and a 2nd packaging apparatus, and can respond appropriately, when the packaging capacity requested | required is high.

  For example, it is assumed that the packaging capacity (maximum number of packaging per minute) in both packaging apparatuses is 200 packaging / minute, and the total packaging capacity is 400 packaging / minute. In this case, for example, if a sheet aggregate is constituted by two blister sheets and the sheet aggregate is supplied to the packaging device side at a rate of 400 aggregates / minute, the sheet accumulation is performed without stopping the production line. In order to wrap the body, it is necessary to make maximum use of the packaging capabilities of both packaging devices. Therefore, in this case, the first conveying means and the second conveying means each receive and deliver the two sheet stacks 100 times per minute (that is, receive 200 sheet stacks per minute). And delivery). Thereby, a sheet | seat assembly can be appropriately distributed to a 1st packaging apparatus and a 2nd packaging apparatus.

  In addition, in the above-described means 1, since both the conveying means are each provided with a holding pair made up of a pair of holding means in an annular shape, a set of four holding means is arranged in an annular shape in a single unit. The turning radius when each holding means makes a circular movement can be made smaller than that of the conveying means. As a result, coupled with the fact that both conveying means are arranged next to each other, the increase in size of the apparatus can be effectively suppressed.

  In addition, since the turning radius of the holding means can be made smaller, the components of the apparatus such as the holding means operate with a relatively small acceleration. Therefore, it is not necessary to make the drive system of the device stronger or to increase the rigidity of the components to cope with the increase in acceleration, and effectively suppress the increase in various costs related to the manufacture of the device. can do. Furthermore, since the centrifugal force applied to the sheet stack is relatively small, it is not necessary to increase the holding force of the holding means. Therefore, it is possible to more reliably prevent a situation in which the sheet stack is damaged as the holding force increases.

Mean 2. The first conveying means can deliver the two sheet stacks held in the first holding pair from the first holding pair disposed at a predetermined inter-conveying means delivery position to the second conveying means. Configured,
The second conveying means is configured to be able to receive the two sheet stacks delivered from the first conveying means by the second holding pair disposed at a predetermined receiving position between the conveying means. The blister sheet conveying apparatus according to claim 1, characterized in that:

  According to the above means 2, when it is possible to appropriately distribute the sheet stack between the two packaging apparatuses and when a very high packaging capacity is not required, the sheet stack is transferred from the first transport means to the second transport means. By handing over, the sheet assembly can be packaged using only the second packaging device. That is, according to the above-mentioned means 2, according to the required packaging capacity, an operation mode in which the sheet aggregate is distributed and sent to both the packaging apparatuses, and the sheet aggregate is concentrated only on one of the packaging apparatuses. The operation mode to be sent automatically can be easily switched. Therefore, it is not always necessary to use both packaging devices, and the cost for packaging can be reduced.

  For example, it is assumed that the packaging capacity in both packaging apparatuses is 200 packaging / minute, and the total packaging capacity is 400 packaging / minute. In this case, for example, if a sheet stack is composed of four blister sheets, and the sheet stack is supplied at a rate of 200 stacks / min to the packaging apparatus side, the sheet stack is not stopped. Wrapping the body can be done sufficiently with only one packaging device. Therefore, in this case, the first conveying unit receives the sheet stack from the upstream side and delivers the received sheet stack to the second conveying unit at a rate of 50 times per minute. Control is performed (that is, 100 sheet stacks are received and delivered per minute). Further, the second conveying means receives the sheet stack at a rate of 100 per minute from the upstream side, and also receives the sheet stack from the first transport means at a rate of 100 per minute, and receives the received sheet stack. The body is controlled to be delivered to the second receiving port at a rate of 200 per minute. Thereby, a sheet | seat assembly can be distributed only to a 2nd packaging apparatus, and the packaging process using only a 2nd packaging apparatus can be performed.

  Means 3. In the operation mode in which the sheet stack is transferred from the first conveying unit to the second conveying unit, one of the two second holding pairs adjacent to each other along the cyclic movement direction is supplied from the upstream side. The other of the two second holding pairs is configured to receive the sheet stack delivered from the first transport means. The blister sheet conveying apparatus according to claim 2, characterized in that:

  According to the means 3, in the second conveying means, one of the two adjacent second holding pairs receives the sheet stack supplied from the upstream side, and the other of the two second holding pairs is The sheet stack delivered from the first conveying means is received. That is, each second holding pair is configured to always receive a sheet stack from a certain target. Accordingly, it is possible to more reliably prevent the processing related to delivery and receipt of the sheet stack from being more reliably prevented, and to achieve stable operation of the apparatus.

Means 4. A first intake conveyor capable of linearly conveying the sheet assembly delivered to the first receiving port to the first packaging device;

The tables 11 and 21 are controlled so as to be the same number as half of the supply amount.

  For example, it is assumed that 800 PTP sheets 1 are manufactured per minute by the PTP packaging machine, and these PTP sheets 1 are conveyed to the stacking device 41. Here, assuming that the sheet stack 7 is composed of two PTP sheets 1, 400 sheet stacks 7 are supplied to the blister sheet transport device 30 per minute, and are sent to the transport devices 10 and 20. In each case, 200 sheet assemblies 7 are supplied per minute. In such a case, the control device 81 controls the transfer devices 10 and 20 so that the turning movement of the holding pairs 12 and 22 is intermittently performed 100 times per minute. That is, the receiving operation of the sheet stack 7 is performed 100 times per minute, and the operations of the conveying devices 10 and 20 are controlled so that 200 sheet stacks 7 can be received per minute. The movement time of the holding pairs 12 and 22 when moving between the positions P11 to P14 and P21 to P24 and the temporary stop time of the holding pairs 12 and 22 at the positions P11 to P14 and P21 to P24, respectively, The setting is appropriately set according to the supply amount of the sheet stack 7 from the stacking device 41 to the blister sheet conveying device 30.

  In addition, the control device 81 moves up the holding operation mechanisms 13 and 23 arranged at the receiving positions P11 and P21 at the timing when the holding pairs 12 and 22 are temporarily stopped. The holding operation mechanisms 13 and 23 are moved downward at the timing immediately after being supplied. Thereby, the sheet stack 7 supplied from the stacking apparatus 41 is sequentially held by the holding pairs 12 and 22 arranged at the receiving positions P11 and P21. The second holding operation mechanism 23 arranged at the inter-conveying means receiving position P24 is controlled so as not to operate.

  For example, as shown in FIG. 13, when the sheet stack 7 is composed of two PTP sheets 1, each time the stacking operation is performed in the stacking apparatus 41, the sheet stack 7 is moved to each conveying device 10. , 20, the supplied sheet stack 7 is sequentially held by holding pairs 12, 22 arranged at the receiving positions P 11, P 21.

  13 to 16 schematically illustrate the stacking operation performed in the stacking device 41 and the operation of the holding pairs 12 and 22 (movement / temporary stop), and the states of the transport devices 10 and 20. It is explanatory drawing containing the state diagram etc. which are shown in FIG. 13 to 16, the fact that the sheet stack 7 is supplied from the stacking device 41 to the conveying devices 10 and 20 is indicated by dotted arrows. Furthermore, in the state diagram schematically showing the states of both conveying devices 10 and 20, the receipt and delivery of the sheet stack 7 are indicated by solid arrows. In addition, in the state diagram, a black circle, a black rectangle, a white circle, and a white circle corresponding to each holding pair 12 and 22 in order to make it easier to grasp the state of both the transfer devices 10 and 20. Show the rectangle together. In each figure, the time t required for the stacking operation is always constant.

  Furthermore, the control device 81 operates the transfer mechanisms 14 and 24 arranged at the delivery positions P12 and P22 outward from the shaft portions 11a and 21a at the timing when the holding pairs 12 and 22 are temporarily stopped. As a result, the two sheet stacks 7 held by the holding pairs 12 and 22 located at the delivery positions P12 and P22 are pushed out toward the intake conveyors 61 and 62, respectively, and delivered to the receiving ports 61r and 62r. . The first transfer mechanism 14 disposed at the inter-transport means delivery position P14 is controlled so as not to operate.

  By controlling the blister sheet conveying device 30 as described above, each time the holding pair 12, 22 moves in position, the sheet stack 7 is received from the stacking device 41 and the sheets are stacked at both the receiving ports 61r, 62r. Delivery of the body 7 is performed. As a result, the sheet stack 7 supplied to the blister sheet conveying apparatus 30 is equally distributed to the packaging apparatuses 51 and 52 by the both conveying apparatuses 10 and 20.

  Next, a case where the blister sheet conveying device 30 is operated in a concentrated conveying manner will be described. In this case, the rotation direction of the first table 11 is set in the direction that is the shortest path from the first receiving position P11 to the inter-transport means delivery position P14. On the other hand, the rotation direction of the second table 21 is set to be the same as the rotation direction in the distributed conveyance mode. As a result, in this embodiment, the rotation directions of both tables 11 and 21 are set counterclockwise.

  In addition, the control device 81 is configured such that the number of intermittent turning movements (position movement times) of the second holding pair 22 per minute is from the stacking device 41 to the conveying devices 10 and 20 per minute. The second transport device 20 is controlled so as to be the same as the supply number.

  For example, when 100 sheet aggregates 7 are supplied to each of the conveying devices 10 and 20 per minute, the second holding pair 22 is swung intermittently 100 times per minute. The second transfer device 20 is controlled. The moving time of the second holding pair 22 when moving between the positions P21 to P24 and the temporary stop time of the second holding pair 22 at each position P21 to P24 are determined from the stacking device 41 to the blister sheet conveying device 30. Is appropriately set according to the supply amount of the sheet assembly 7 with respect to the above.

  On the other hand, in the control device 81, the number of intermittent swiveling movements (position movements) of the first holding pair 12 per minute is half of the number of sheet aggregates 7 supplied to the conveying devices 10 and 20 per minute. The first transport device 10 is controlled so as to be the same number.

  For example, when 100 sheet stacks 7 are supplied to the respective conveying devices 10 and 20 per minute, the first holding pair 12 is swung intermittently 50 times per minute. The first transfer device 10 is controlled. Thereby, while the 1st holding | maintenance pair 12 performs a pause and a movement once, the 2nd holding | maintenance pair 22 will perform a pause and a movement twice. In addition, while the 1st holding | maintenance pair 12 is paused, the timing of the movement of both the holding pairs 12 and 22 and a pause is controlled so that the 2nd holding | maintenance pair 22 pauses twice.

  Further, the control device 81 operates the first holding operation mechanism 13 disposed at the first receiving position P11 at the timing when the first holding pair 12 is temporarily stopped. On the other hand, every time the second holding pair 22 pauses twice, the control device 81 operates the second holding operation mechanism 23 arranged at the second receiving position P21 once. Thereby, the sheet stack 7 supplied from the stacking device 41 is sequentially held by the holding pairs 12 and 22 moved to the receiving positions P11 and P21, but the second holding pair 22 is swung twice. In addition, the sheet stack 7 supplied from the stacking apparatus 41 is received and held only once. As a result, only one of the pair of second holding pairs 22 adjacent in the cyclic movement direction receives the sheet stack 7 from the stacking device 41 and holds it.

  For example, as shown in FIGS. 14 to 16, when the sheet stack 7 is composed of four, six, or ten PTP sheets 1, the stacking device 41 performs the stacking operation twice, three times, or five times. After being performed, the sheet stack 7 is supplied to the conveying devices 10 and 20. At this time, the first holding pair 12 arranged at the first receiving position P11 sequentially holds the supplied sheet stack 7. On the other hand, the second holding pair 22 arranged at the second receiving position P21 holds every other supplied sheet stack 7. 14 shows a case where the number of PTP sheets 1 constituting the sheet stack 7 is four, and FIG. 15 shows a case where the number of PTP sheets 1 constituting the sheet stack 7 is six. Indicates a case where the number of PTP sheets 1 constituting the sheet assembly 7 is ten.

  Further, the control device 81 determines a predetermined timing when the first holding pair 12 is temporarily stopped (in the present embodiment, substantially the same timing as the operation timing of the second holding operation mechanism 23 arranged at the second receiving position P21). ), The second holding operation mechanism 23 arranged at the inter-conveying means receiving position P24 is operated. As a result, the second holding pair 22 arranged at the inter-transport means receiving position P <b> 24 can receive and hold the sheet stack 7 from the first transport device 10.

  Furthermore, the control device 81 controls the first transfer mechanism 14 so that the first transfer mechanism 14 disposed at the first delivery position P12 does not operate. As a result, the sheet stack 7 is not delivered from the first transport device 10 to the first receiving port 61r.

  On the other hand, the control device 81 is when both the holding pairs 12 and 22 are temporarily stopped, and at almost the same timing as when the second holding operation mechanism 23 arranged at the inter-transport means receiving position P24 is operated. Then, the first transfer mechanism 14 disposed at the inter-transport means delivery position P14 is operated. As a result, the sheet stack 7 is delivered from the first transport device 10 to the second transport device 20, and the sheet stack 7 delivered by the second holding pair 22 disposed at the inter-transport means receiving position P24. Retained.

  The second holding pair 22 that receives the sheet stack 7 from the first conveying device 10 includes a pair of second holding pairs 22 that are adjacent to each other in the circulation direction and that receives the sheet stack 7 from the stacking device 41. Are considered to be different. As described above, in this embodiment, one of the two second holding pairs 22 adjacent in the cyclic movement direction is in charge of receiving the sheet stack 7 supplied from the stacking device 41, and the two second holding pairs 22. The other of the holding pairs 22 is in charge of receiving the sheet stack 7 delivered from the first conveying device 10. For example, in the example illustrated in FIGS. 14 to 16, the second holding pair 22 corresponding to the black circle and the white circle is in charge of receiving the sheet stack 7 supplied from the stacking device 41, and the black rectangle and the white The second holding pair 22 corresponding to the blank rectangle is in charge of receiving the sheet stack 7 delivered from the first conveying device 10.

  In addition, the control device 81 operates the second transfer mechanism 24 disposed at the second delivery position P22 at the timing when the second holding pair 22 is temporarily stopped. As a result, the two sheet stacks 7 held by the second holding pair 22 are each pushed out toward the second intake conveyor 62 and delivered to the second receiving port 62r. As a result, the sheet stack 7 directly supplied from the stacking apparatus 41 and the sheet stack 7 received from the first transport apparatus 10 are alternately delivered to the second receiving port 62r.

  By controlling the operation of the blister sheet conveying apparatus 30 as described above, the sheet aggregate 7 supplied from the accumulating apparatus 41 to both the conveying apparatuses 10 and 20 is conveyed to the first packaging apparatus 51 side. Instead, it is transported only to the second packaging device 52.

  As described above in detail, according to the present embodiment, in the distributed conveyance mode, the first receiving port 61r (the first receiving port 61r) Can be delivered to the first packaging device 51 side), and the second transport device 20 delivers the remaining two rows of sheet aggregates 7 to the second receiving port 62r (second packaging device 52 side). be able to. Thereby, the sheet | seat assembly 7 can be appropriately distributed with respect to the 1st packaging apparatus 51 and the 2nd packaging apparatus 52, and can respond appropriately, for example when the required packaging capacity is high.

  On the other hand, when the packaging capacity is not so high, the blister sheet conveying device 30 is operated in the centralized conveying mode, and the sheet stack 7 is delivered from the first conveying device 10 to the second conveying device 20, The sheet assembly 7 can be packaged using only the second packaging device 52.

  Thus, in this embodiment, according to the required packaging capacity, a mode (distributed transport mode) in which the sheet stack 7 is distributed and sent to both the packaging devices 51 and 52 side, and a second packaging device 52. It is possible to easily switch the mode (concentrated transport mode) in which the sheet stack 7 is intensively fed only to the side. Therefore, it is not always necessary to use both the packaging devices 51 and 52, and the cost for packaging can be reduced.

  Further, since both conveying devices 10 and 20 are formed by holding holding pairs 12 and 22 each having a pair of holding means 12a and 22a in an annular shape, a set of four holding means is annularly formed as a single unit. The turning radius when the holding means 12a and 22a make a circular movement can be made smaller than that of the conveying means provided. As a result, the size of the blister sheet conveying device 30 can be effectively suppressed in combination with the two conveying devices 10 and 20 being arranged side by side.

  Further, since the turning radii of the holding means 12a and 22a can be made smaller, the components of the blister sheet conveying apparatus 30 such as the holding means 12a and 22a and the tables 11 and 21 operate with relatively small acceleration. It will be. Therefore, it is not necessary to make the drive system of the blister sheet conveying apparatus 30 stronger or to increase the rigidity of the constituent parts in order to cope with the increase in acceleration, and increase the various costs related to the manufacture of the apparatus. It can be effectively suppressed. Further, since the centrifugal force applied to the sheet stack 7 is relatively small when the holding means 12a and 22a are pivoted, it is not necessary to increase the holding force of the holding means 12a and 22a. Accordingly, it is possible to more reliably prevent a situation in which the sheet stack 7 is damaged as the holding force increases.

  Further, when the blister sheet conveying device 30 is operated in a concentrated conveying manner, one of the two adjacent second holding pairs 22 in the second conveying device 20 is the sheet stack 7 supplied from the accumulating device 41. The other of the two second holding pairs 22 is in charge of receiving the sheet stack 7 delivered from the first conveying device 10. That is, each second holding pair 22 always receives the sheet stack 7 from a certain target. Accordingly, it is possible to more reliably prevent the processing related to the delivery and receipt of the sheet stack 7 from occurring, and to achieve a stable operation of the blister sheet conveying apparatus 30.

  In addition, since the first intake conveyor 61 and the second intake conveyor 62 are arranged in parallel, the blister sheet conveying device 30 is compared with the case where the two intake conveyors 61 and 62 extend in different directions. Can be reliably suppressed.

  In addition, it is not limited to the description content of the said embodiment, For example, you may implement as follows. Of course, other application examples and modification examples not illustrated below are also possible.

  (A) In the above embodiment, the blister sheet transport device 30 is configured to distribute the sheet stack 7 evenly to the two packaging devices 51 and 52 (equivalent transport mode), or the sheet stack 7 to the second packaging device. It is configured to operate in a mode (concentrated transport mode) in which only 52 is transported. On the other hand, you may comprise so that the blister sheet | seat conveyance apparatus 30 may be operated by the aspect (uneven conveyance aspect) which distributes the sheet | seat assembly 7 with respect to both the wrapping apparatuses 51 and 52 unevenly.

  For example, in the first transport device 10, half of the sheet stack 7 supplied from the stacking device 41 is transferred to the first receiving port 61r (first packaging device 51 side), and the remaining half is transported to the second. On the other hand, in the second transport device 20, the sheet stack 7 received from the stacking device 41 and the first transport device 10 is transferred to the second receiving port 62r (second packaging device 52 side). And may be configured to deliver all of them. In this case, ¼ of the sheet stack 7 supplied from the stacking device 41 to the blister sheet transport device 30 can be transported to the first packaging device 51, and the supplied sheet stack 3/4 of 7 can be transported to the second packaging device 52. Of course, the ratio of the number of sheet stacks 7 transported to each of the packaging devices 51 and 52 can be changed by adjusting the number of sheet stacks 7 delivered from the first transport apparatus 10 to the second transport apparatus 20. it can.

  With this configuration, it is possible to cope with a case where the number of packages by the first packaging device 51 and the number of packages by the second packaging device 52 are desired to be different. For example, when a binding device is used as the first packaging device 51 and a pillow packaging device is used as the second packaging device 52, the number of sheet assemblies 7 to be band-bound and the number of sheet assemblies 7 to be pillow-wrapped. It is possible to deal with cases where and are different.

  (B) The number of holding pairs 12 and 22 in the above embodiment is an example, and the number of holding pairs 12 and 22 can be changed as appropriate. Therefore, for example, each of the transfer devices 10 and 20 may have 6 or 8 holding pairs 12 and 22, respectively. Of course, the number of holding pairs 12 and 22 may be an odd number, or the number of first holding pairs 12 and the number of second holding pairs 22 may be different.
