Description

Detailed Description of the Invention (Industrial Application Field) The present invention relates to a method for transporting packages, mainly drug packages in the pharmaceutical field, until they are packed into cardboard cartons, and a loader, an unloader, and a case used in the method. It is related to.

(Prior Art) Conventionally, in the pharmaceutical field, packaging of tablets, capsules, etc. has been carried out through the following steps.

As shown in FIG. 2, first, 1. Fill an FTP sheet or strip sheet with tablets or capsules.

2. Hold the 107 sheets together with the blurred and throat sides facing inside.

3. Stack 5 tied sheets (2 sheets).

4. Wrap these 10 sheets (2 x 5) of sheet banding film to make a bundle.

5. Stack 5 bundles of 10 sheets. 6. Band and fix these 50 sheets (IOX 5 ) again to form 5 bundles.

(There are cases where 5 bundles are packed in one box.

) 7. Add (put on) silica gel.

8. Turn this into billow.

9. Pack the billows into individual boxes by hand.

10. Pack individual boxes into cardboard cartons by hand.

As described above, in order to pack drug packages such as bundles of PTP sheets or strip sheets and wrapping them in billow, that is, billow packages, into individual boxes, it is necessary to directly box the drug packages by hand or using an individual box cartoner. Was.

Conventionally, as shown in Figure 3 (a), drug packaging was done on a mechanized line and individual boxes and cardboard cartons were packed manually, and as shown in Figure 3 (b), drug packaging was mechanized. The method used was to mechanize the packing of individual packaging and cardboard cartons using individual packaging cartoners and cardboard casers. The cardboard boxes filled with individual boxes are then stocked in a warehouse until shipped.

(Problems to be Solved by the Invention) The conventional method of transporting drug packages until packaging them into individual boxes requires a lot of labor when individually packaged and packed into cardboard cartons by hand, as shown in Figure 3 (a). Something happened.

Packing into individual boxes and cardboard cartons as shown in FIG. 3 (b) using an individual box cartoner or cardboard caser reduces labor, but requires a large amount of equipment investment and space.

In addition, the processing time for mechanized drug packaging lines, individual box cartoners, and cardboard casers is different, and in the case of mechanized lines for billow packaging, the processing times for individual box cartoners and cardboard casers are the same. It is about 5 times faster than a mechanized packaging line, so if a mechanized packaging line, individual box cartoners, and cardboard casers are lined up in rows as shown in Figure 3 (b), the individual The company responded by slowing down the processing speed of cartoners and cardboard casers.

As a way to speed up the processing speed and increase efficiency of individual box cartoners and cardboard casers, the method shown in Figure 3 (c) can be considered, but if the packaging form and type of drug are changed, The mechanized drug packaging line had to be stopped to adjust the cartoner and cardboard casing.
A problem arises in that efficiency becomes low. It is also necessary to provide a merging device for drug packaging.

The present invention aims to provide a packaging form that meets user requirements without stopping the mechanized drug packaging line, and to provide an efficient transportation method that fully utilizes the throughput of individual box cartoners and cardboard casers. It is an object of the present invention to provide an efficient storage method that can accommodate changes in the size of packages, and to provide a loader and an unloader for achieving the above method.

(Means for Solving the Problems) In order to achieve the above objects, the present invention provides the following method for transporting packages, and a loader, an unloader, and a case used in the method. .

That is, a temporary stocker is provided between a loader that stores individually wrapped items in a case and an unloader that takes out individual wrapped items from the case, and after temporarily storing the cases containing the individually wrapped items, the loader removes the individually wrapped items from the case. This is a method of transporting packages in which individual packages are taken out again using an unloader.

The case used in the above-mentioned conveyance method is a case in which the individual packages can be stored vertically using a partition plate, and the partition plate can be raised and lowered so that the individual packages can be transferred toward the conveyor.

Further, the loader used in the above-mentioned transport method is a loader having the following configuration.

In other words, there is an inverting device that stands up the individual packages that have been horizontally transferred by the supply conveyor, and an inverter that supports the upright individual packages in the upright state while following the subsequent individual packages that are sent out by the inverter. The front receiver is a plate that sequentially retreats to line up a plurality of individual packages, and the front receiver is a plate device that holds a certain number of vertical individual packages lined up between the front and rear feeding claws between the storage blades of the slat conveyor. A pusher device transfers and sets the individual packages transferred to the storage blade of the slat container, and the multiple rows of individual packages transferred to the storage blade of the slat container are held between the front and rear multi-column feed claws, and the middle package is sent one by one from the case separation device. This loader consists of a multi-row transfer device that transfers and loads cases into cases with partition plates, and a case transport conveyor that temporarily transfers the cases in which multiple rows of individual packages are transferred to the partition plates toward a stocker.

Additionally, the following device is used to invert the loader.

In other words, the front support, which can freely move back and forth with a cylinder, is perpendicular to the plate, and the bottom support is a swinging arm that fixes the plate. It is an inverted device which is provided with an actuating cylinder for moving the plate, and the front receiver is provided with shutters on the left and right sides of the rear surface of the plate to support the left and right sides of the last individual package in a group of individual packages in an upright state.

Further, the following unloader is used as the unloader.

In other words, there is a container that temporarily transfers cases containing upright individual packages between multiple rows of partition plates from a stoker toward a multi-row transfer device, and a row of individual packages on the partition plates that are raised from the case. A multi-row transfer device that transfers the individual packages on the slat conveyor between the storage blades of the slat conveyor by holding them between the front and rear feed claws, and a rear feed claw of the pusher with the forward feed claw of the pusher raised. This unloader is comprised of a take-out device that transfers the items one by one from an upright state to a horizontal state toward a discharge conveyor.

(Function) The conveying method of the present invention provides a temporary stocker between the drug packaging mechanized line, the individual box cartoner, and the cardboard caser, so that when the packaging form or type of drug is changed, the individual box cartoner By temporarily stocking the packaged items in a stocker, the time required for adjusting the cardboard casing and the time required for adjusting the cardboard caser is reduced, thereby forming an efficient transportation method that operates without stopping the mechanized drug packaging line.

Since the capacity of individual packaging machines and cardboard cartoning machines is higher than that of mechanized drug packaging lines, there is a gap between multiple mechanized pharmaceutical packaging lines and one individual packaging machine and cardboard cartoning machine. multiple loaders
By providing a stocker and an unloader, an efficient transport method is constructed.

(Example) Figure 1 shows the conveying method of the present invention. When the throughput of an individual cartoning machine and a cardboard cartoning machine is five times that of a mechanized line, parallel A loader is connected to each end of the mechanized line, and the individual packages of drugs stacked in cases by each loader are temporarily stored in temporary stockers in their cases, which has a processing capacity five times that of the loader. The product is carried into an individual cartoning machine using one unloader, and then packed into cardboard boxes by a cardboard cartoning machine.

According to the transport method described above, the loader-unloader
Since the system does not require an operator, it is more labor-saving and takes up less space than the traditional method of arranging packaging lines in parallel.

However, the capital investment required for the loader and unloader is lower than that for the individual packing machine and the cardboard cartoning machine, since the stocker is inexpensive.

Therefore, to explain the case equipped with a partition plate used in the conveyance method of the present invention, in FIGS. 4 and 5, (
1) is a case, and there are four positioning holes (2) at four corners of the bottom plate (1a).

A positioning boss (5) that fits into the hole (2) is provided on the bottom outer surface of a partition plate (4) equipped with a partition (3) that is installed inside the case (1).

The positioning boss (5) can be pushed up with the four push-up ronds (7) of the inner partition plate (4) and the beam lid (6), and the tip of the push-up rond (7) ) There is a protrusion (8) that fits into the hole.

Inside the case (1) equipped with the partition plates (4) as described above, individual packages (a) are stacked up between the partition plates (3) as shown in Figure 6. The loader loads the individual packages into the stacked state, and the unloader takes out the individual packages from inside the case. Such a loader and unloader are arranged before and after the temporary stocker via conveyor conveyors.

So, to explain the loader, the loader consists of a supply conveyor (A), an inversion device (B), an alignment device (C),
It consists of a row transfer device (D), a case separation device (E), and an individual package loading device (F).

The supply conveyor (A) has the seventh
As shown in Fig. 9, there is a direction changing roller (9), and the individual packages (
a) is changed in its posture in the vertical direction by the direction changing roller (9) and the guide (10), and is moved to the next inclined roller (1).
2). At the end of the inclined roller (12) there is an inversion device (B).

The inversion device (B) has a link (15) with a piston rod (14) of a cylinder (13) as shown in Figure 11.12.13.
) The bottom support that supports the tip of the individual package @J (a) is fixed to the swing arm (17) that swings around the fulcrum (16) via the play (18), The front support that supports the body of the individual package (a) in the direction is a plate (
20), which is moved back and forth by the piston rod of the cylinder (19).

In addition, the swing arm (F) moves the individual packages (a) from the same direction as the inclined rollers (work 2) on the left and right sides of the chute to the upright state.
) is oscillated by the cylinder (13) so as to change the position.

(The front receiver is a play) (20) is placed on the left and right side of the upright rear where the receiver stops the left and right of the last individual package in the group of individual packages.
A cylinder (21a) enters and exits an alignment passageway (24) with alignment guides (23) on the left and right sides.

Therefore, the individual packages (a) that have fallen horizontally in the vertical direction by the inclined rollers (12) are placed on the bottom plate (18).
The receiver is stopped by the cylinder (13), and by rotating the swinging arm (17), the bottom receiver is a plate (1, 8) and the front receiver is a plate (20), and the individually packaged items are transformed into an upright state. and a shank protruding into the alignment passageway (24).
(21) to the left and right sides of the individual packages (a), and the alignment device (C)
forward play) Receive the forward at (25).

When the next individual package is sent, the front receiver is placed on the plate (25
) retreats, and the shutters (21) maintain the right and left sides of the last individual package, so the group of individual packages maintains an aligned upright state.

Therefore, to explain the alignment device (C), the front support plate (25) is designed so that its support plate (30) can be retracted from the shutter (21) position along the guide rod (28), and the rod Res cylinder (
31) allows you to move forward.

Front reception is a play) (25) is also a cylinder (26)
It can be lowered using the piston rod (29).

Therefore, the cylinder (26) is a supporting play) (3
0), and the front receiver moves forward and backward together with the plate (25). This front receiver has a slit slot (27) in the alignment passageway (24) for advancing and retracting the plate (25).

When a certain number of individual packages are lined up in the alignment path (24), the sensor (32) shown in Fig. 12 detects this, and the shutter (21) opens left and right by the shutter cylinder (21a), allowing the group of individual packages to be aligned. Open the left and right sides of the last individual package. The forward feed pawl (33) and the rear feed pawl (34) descend onto the alignment path using cylinders (35) and (36), and clamp the group of aligned individual packages from the front and back.

The forward feed claw (33) and the rear feed claw (34) are connected to the cylinder (
35) It descends at (36) and clamps the lined up group of individual packages.

The group of individual packages held by the pushers is stored between the storage blades of the slat container of the next three-row transfer device (D) by the operation of the Rondress cylinder (38). Although the embodiment is a three-row transfer device, a plurality of rows other than three rows may be used.

At the same time as the pusher (37) holds the group of individual packages, the plate (25) of the front receiver is lowered by the cylinder (26), and then returned to its original position by the rodless cylinder (31) and aligned again. A cylinder (2
6) stands out. Forward feed claw (33) and rear feed claw (34)
(25)
is now inserted.

Further, the front receiver has shock absorbers (40) and (41), respectively, to dampen the back and forth movement of the plate (25) and the back and forth movement of the pusher (37).

The alignment device (C) is configured as described above, and the group of individual packages aligned in the alignment bag W (C) is transported to the next three-row transfer device (D).

Pusher (37) transfers a group of individually packaged items in three rows (D)
When the conveyance is finished, the forward feed claw (33) rises first, and then the rear feed claw (34) also rises. Then, the forward feed pawl (33) and the rear feed pawl (34) are raised and retracted to their original positions to move to the standby position.

Therefore, to explain the three-row transfer device (D), first, the storage blades are arranged so that they can receive one row of individual packages sent from the alignment device (C) as shown in Figure 7.9. , and a slat conhair (43) movable in a direction perpendicular to the alignment device (C).

When one row of individual packages is inserted between the blades (42), the slat conhair (43) rotates, the one row of individual packages moves forward, and the next one is inserted between the next empty blade (42). When rows of individual packages are loaded, and the same operation is repeated to load three rows of individual packages into the slant container, the third row of storage blades (42) move to the third row transfer device ( Stop under D). Then, the 3-row transfer device (D) is activated.

As shown in Figure 7 and Figures 14, 15, and 16, the three-row transfer device (D) is a sulin that fits into the storage blade (42).
The front 3 row feed claws (45) have (44) and the rear 3 rows have a slit (46) that fits into the storage blade (42).
A pusher (48) with a row feed claw (47) arranged at a certain distance is moved left and right by a rodless cylinder (49) along a pole pusher guide (50) of a support (51). It has become.

Therefore, the group of individual packages loaded into the three rows of storage blades (42) is held between the front and rear three rows of feeding claws (45) (47), and the rodless cylinder (49) of the pusher (48)
), the group of individual packages in three rows moves to the left in FIG. 7, moves to the left in FIG. 9, and is conveyed to the next individual package loading device (F).

At the individual package loading device (F) position, a partition plate (4) elevated from the case (1) on the case transport conveyor consisting of a roller conveyor is waiting, and between this partition (3) each row is Groups of individual packages are loaded.

The pusher (4B) has been transferred as described above.
) is returned to its original position by the Rondress cylinder (49).

When moving the pusher (48), use the front and rear three rows of feed claws (45
) (47) have slits (44) and (46), respectively, so the storage blade (42) does not interfere.
The pusher can be moved, and the case (1)
There is no interference with the partition (3) of the partition plate (4) above.

When the pusher (48) has finished transferring the individual packages, the pusher (48) moves back, but at this point the slat conveyor (43) moves between the front and rear three rows of feeding claws (45) and (47). There is no interference between the blade (42) and the pusher (48).

Next, to explain the case separating device (E), the case separating device (E) is located in the position shown in Fig. 9, and the stacked empty cases (with partition plates loaded) are shown in Fig. 19. When the cases are sent by the roller conveyor (52) from the direction of the arrow, the cases stacked on the roller conveyor are stopped by a stopper (53) operated by a cylinder (54) and a link (55). At the stop position, as shown in FIG. 17, the case receiving plate (56) is raised by the cylinder (61) along the guide (57), and the stacked cases are placed on the case receiving plate (56).

Next, the cylinder (58) shown in FIG. 17 is operated, and the lever (60) projects from the left and right through its link (59) to support the second stage empty case.

When the empty case on the second stage is supported by the lever (60), the cylinder (61) is operated and the case receiving plate (56) is lowered, and the empty case on the lowest stage is placed on the roller conveyor (52). When the lowest empty case is placed on the roller conveyor (52), the stopper (53) in Fig. 19 is moved to the cylinder (5).
4), the empty cases at the bottom are freed, and the empty cases are transferred to the 3-row transfer device (D) using the roller conveyor (52).
The individual packaging group loading device shown in FIGS. 7 and 9 corresponding to
F) transported to position. Empty cases in the second and higher stages are supported by a lever (60), and the next case receiving plate (5) is supported by a lever (60).
6), the lever (60) is released and the case holder of the second empty case rests on the plate (56). When the second stage empty case is placed on the case holder (56), the lever (60) protrudes and supports the third stage case. When the third stage case is supported, the case holder is a plate (56)
is lowered, and the empty cases on the second stage are transferred to the individual package group loading device (F) shown in FIGS. 7 and 9 by the three-row transfer device (D).

By repeating the above operations, empty cases are transferred to the 3-row transfer device (
It is supplied to the individual package group loading device (F) position corresponding to D).

Now, the empty case (1) is moved to the second place on the roller conveyor (52).
When it reaches the position shown in Figure 2, the stopper (62) operates to stop the empty case in position.

At this stop position, guides (63) are located on the left and right sides of the roller conveyor (52) in a direction perpendicular to the transport direction, as shown in Figure 7.9.

Further, as shown in FIG. 20, at this stop position 1, the case receivers (64) (64) can be raised and lowered by a piston rod (66) of a cylinder (65).

Furthermore, there is a lifter (6) for the partition plate mounted along the guide (68) in the cylinder (67).

Therefore, when the empty case (1) stops at the stopper (62), the cylinder (65) operates and the case receiver (6
4) Raise (64) and move the roller conveyor (52)
Lift the case (1) from the

When the case is lifted into a predetermined position by the case receiver (64), the cylinder (67) is activated to raise the partition plate lifter (6), and its push-up rod (7) moves the positioning boss ( 5) to the same level as the slat conveyor (43) of the 3-row transfer device (D). At that position, the lock (69) of the lid (6)
) is set by hitting the sensor (70).

When the partition plate (4) is lifted to the same level as the slat conveyor (43) by the push-up rod (7), the group of individual packages is moved to the guide (63) by the pusher (48) of the 3-row transfer device (D). Partition (3) of middle partition plate (4) in 3 rows along
) is loaded between.

In this case, since there are no guides on either side of the partition plate (4), an outer guide (74) as shown in FIG. 7.9 is used in addition to the guide (63) as necessary. Once loaded, the pusher (48) moves back, so the cylinder (6
7) to lower the partition plate lifter (6), load the partition plate into the case (1), and lower the cylinder (6).
In step 5), the case receiver (64) is lowered and the case is transferred to the roller conveyor (52). At that time, the stopper (62) shown in Fig. 22 has been lowered and the push-up rod (7) has been displaced from the hole (2) in the case and the positioning boss (5) of the partition plate (4). The cases loaded with the group of individual packages are conveyed by a roller conveyor (52) toward a temporary stocker (71) shown in FIG. 9. Then, the cases loaded with the group of individual packages are temporarily stored in the stocker (71) and transported toward the next unloader.

According to the one shown in FIG. 7, there is a case stop positioning cylinder (72) and a stopper (73) that moves up and down.
).

In addition, although some outer circumferential guides (74) are shown, any design changes may be made within the spirit of the present invention.

Next, the unloader will be explained.

The unloader consists of a supply conveyor (G), an individual package discharge device (I (), a 3-row transfer device (I), a take-out device (J), and a discharge conveyor (K). (H) has the same structure as the individual package loading device (F) of the loader.

Now, the case (1) stored in the -hour stocker (71) is transferred by the roller conveyor (75) which is the supply conveyor (G) shown in Fig. 8.10, and at its stop position, the case (1) is transferred to the -hour stocker (71). .22 Individual packaging discharge device with the same structure as in Figure 22 (H
) works. That is, the stopper (62) operates at the stop position, and the case (1) loaded with the group of individual packages is stopped. Then, the cylinder (65) similar to the one in Fig.
is activated to lift the case (1) with the case holder (64), and the cylinder (67) is further activated and the lifting rod (7) of the partition plate lifter (6) lifts the partition plate (4) to the case ( 1) Lift it up.

Then, when the partition plate (4) is lifted to the same level as the slat conveyor (76) shown in FIG.
The three-row transfer device (1) shown in Figure 25 is activated.

The 3-row transfer device (I) is arranged in front 3 rows with a certain distance between them.
A pusher (79) consisting of a row feed claw (77) and a rear three row feed claw (78) is supported by a column (80), and is guided by a ronless cylinder (81) (82) (83).
move back and forth along.

In addition, there are partition plates (
There are slits (84) (84) that fit into the partitions (4), so the three rows of front and rear feed claws (77) (78) can be moved up and down by the Rondress cylinder (85).

Since the three-row transfer device (1) is configured as described above,
Push the pusher (79') at the raised partition plate (4).
is lowered by a rodless cylinder (85), the group of individual packages in three rows is held between the front and rear three rows of feeding claws (77) (78), and then conveyed by a rodless cylinder (81) on a slat conveyor (
76).

The three rows of conhair packages are loaded between the storage blades (86) of the slat conveyor (76) by means of a pusher (79). When the pusher (79) is completely retracted, it is raised by the rodless cylinder (85), and further retreated by the rodless cylinder (81) to move to the next standby position. The reason why the storage blade (86) of the slat conveyor rises is when the slat conveyor storing the group of individual packages rotates.
This is to avoid collision with the row feed claw (77).

At that time, use the lifter (6) for the middle partition plate (4) to remove the middle partition plate (4).
is charged into the case (1), and when the partition plate (4) is completely inserted into the case, the case receiver (64) is lowered and the case (1) is transferred to the roller conveyor as shown by the arrow in Fig. 10. (7
5) and transported toward the empty case stacking position (87).

The group of individual packages transferred to the slat container (76) is conveyed to the next unloading device (J). The take-out device (J) is attached to the rear feed claw (87) as shown in Figures 26, 27, and 28.
) and a forward feed claw (88
) and the pusher (91).
1) The slat conveyor will stop when it reaches the position. In this state, the rear feed claw (87) of the pusher is in a state where it is supporting one row of individual packages later.

Next, the forward feed claw (88) of the pusher is lowered by the rodless cylinder (90), and the group of individual packages is held between it and the rear feed claw (87).

The pusher (91) moves with the rodless cylinder (89) and pushes out the group of individually packaged items from the storage blade of the slat con hair, and when it comes to the shutter (93), the advance claw (88) moves with the rodless cylinder (90). ), and since the shutter (93) is opened by the cylinder (94), the individual packages are pushed by the backward feed claw (87) in an upright state.

Therefore, the individual packages are discharged one by one by the backward feed claw (87) toward the discharge conveyor (96).

At that time, the shutter (93) with guides (92) on the left and right
) There is a step between the passageway (97) and the discharge container (96), and between this there is a sloped plate (95) that slopes forward downward, where individual packages that are upright are tilted forward and leveled. They are discharged one by one onto a discharge conveyor (96).

When a row of individual packages is sent out, the forward feed claw (88) descends, and the pusher (91) moves back to its original position between the empty storage blades together with the rear feed claw (87). When the process is finished, the slat conveyor moves one space and takes a standby position for discharging the next row.

The discharge conveyor (K) consists of a so-called first discharge conveyor (96) and a second discharge conveyor (97) as shown in Fig. 8.10.
), all of which have variable speeds.

Thus, from the second conveyor (97) to the cartoner (9
In step 8), the individual packages are transferred and packed into individual boxes and cardboard cartons.

Empty cases from the unloader are transferred to a stacking device (87), and the stacked cases are transferred to a case separating device by an unmanned conveyor, a conveyor, or the like.

In any case, in the loader, the individual packages are fed in a horizontal state by the supply conhair (A), the attitude is changed to an upright state by the inversion device (B), and the individual packages of a fixed number are fed by the alignment device (C). are arranged and sent to the 3-row transfer device (D), and in this transfer device (D), the 3-row individually packaged groups are transferred to the case separation device (
The individual packages sent from E) are loaded into the partition plate of the case at the position of the filling device (F), and the case is transferred to the stocker and temporarily stored there. In the unloader, the cases loaded with the group of individual packages are transported from the stocker to the individual package discharge device (H) by the supply conveyor (C), and then 3
A group of individual packages is taken out from the case by the row transfer device (I),
The group of individual packages is pushed out one row at a time by the next take-out device (J), and one by one, the individual packages are changed from the end of the take-out device to a horizontal position and are discharged onto the discharge conveyor (K). It is now being transferred to

In other words, by simultaneously unloading groups of individual packages from three rows using the three-row transfer device, it is possible to save time for setting cases containing groups of individual packages on the unloader, and to continuously supply individual packages to the cartoner. It can be done in a specific manner.

Therefore, packages can be transported rationally using a case with a partition plate, a loader, an unloader, and a time stocker.

(Effects of the Invention) According to the present invention, a plurality of loaders - 21 unloaders -
By installing a temporary stocker between the mechanized drug packaging lines, it is possible to respond to changes in packaging formats and drug types without stopping the mechanized drug packaging lines, individual box cartoners, and cardboard carton filling machines. By providing a transportation method according to the processing capacity of the packaging process, the packaging process can be made labor-saving, space-saving, and efficient.

However, since the case of the present invention has a partition plate that can be raised and lowered in the case, it is easy to carry in individual packages from the slat conveyor and carry them out from the partition plate to the slat conveyor.
Moreover, since it can be stacked vertically and loaded into the case of individually packaged items,
Even if the size of individually packaged items changes, it can be accommodated and efficiently stored.

In addition, the loader changes the posture of individual packages from a horizontal state to an upright vertical position, so that a plurality of individual packages can be easily loaded into several rows of cases, making it easy to temporarily store them in a stocker.

Furthermore, the unloader can take out the vertically stacked individual packages from the case and easily change the posture from an upright position to a horizontal position, making it easy to handle the cartoner.
