Description

Detailed Description of the Invention (Field of Industrial Application) The present invention provides a cut sheet for transporting cut sheets obtained by cutting a package sheet containing a drug into a predetermined number of sections to a binding machine. The present invention relates to a conveyance device.

(Prior Art) Conventionally, in a drug packaging machine, a long packaging sheet folded in half is intermittently transferred horizontally with the folded part at the bottom, and a navy blue seal is first applied, and then the vertical seal is applied. Compartments arranged one after the other in the transfer direction are formed between the compartments, and a desired drug is subsequently introduced into the compartments, and then a horizontal seal is applied to the upper opening of the compartment to seal the drug in the compartments. ing.

Then, the long packaging sheet in which the medicine is sealed in each compartment is cut into cut sheets by a cutter into a predetermined number of compartments, and the cut sheets are collected in a predetermined number according to the prescription and tied by a binding machine. It has become so.

(Problem to be Solved by the Invention) However, in the above-mentioned conventional cut sheet conveying device, the cut sheet cut by the canter is simply conveyed by sliding and falling within the guide, so it cannot be continuously conveyed. The work of collecting a predetermined number of cut sheets, correcting the misalignment of the cut sheets, and sending the cut sheets to the binding machine are all performed manually.

Furthermore, since the cut sheets are continuously conveyed while the binding machine is performing the binding operation, it is necessary to provide a place to store the cut sheets immediately before the binding machine, resulting in high work costs.

The purpose of the present invention is to solve the problems of the conventional cut sheet conveying device described above, and to solve the problems of the conventional cut sheet conveying device, to collect a predetermined number of continuously conveyed cut sheets, to correct misalignment between the cut sheets, and to solve the problems of the conventional cut sheet conveying device. It is an object of the present invention to provide a cut sheet conveying device that can automatically carry out the entire operation of conveying cut sheets to a binding machine, and does not require a space to store cut sheets that are continuously conveyed.

(Means for Solving the Problems) To achieve this, the cut sheet conveying device of the present invention cuts a packaged sheet in which drugs are packaged into a predetermined number of sections and conveys the obtained cut sheets to a binding machine. A cut sheet conveying device for use in the present invention is provided with a reversing member having a cut sheet placing portion formed with at least a wall for leaning the cut sheets, and having a cutter and a sheet introduction portion at one side end, the reversing member is swingably supported by support means.

In normal times, the reversing member is placed in a position where the cut sheets can be stacked against one wall of the reversing member, and in a position where the stacked cut sheets are dropped during reversing. placed in

Further, in order to swing the support means, a protruding means is provided, and the ejecting speed is high at the start of ejecting and then decreases.

Furthermore, a cut sheet stopper is formed on the other end of the reversing member facing the cut sheet introducing portion, and the cut sheets stacked against one wall of the reversing member are pressed against the wall. A holding means is provided.

(Function) According to the present invention, as described above, the reversing member is provided, which has a cut sheet placement portion formed with at least a wall for leaning the cut sheet, and has a cut sheet introduction portion at one side end. The reversing member is swingably supported by support means, and the reversing member is normally placed at a position where the cut sheets can be stacked against a wall, and when reversing, Because it is placed in a position where stacked cut sheets are dropped,
A predetermined number of cut sheets can be collected in the reversing member, and the sheets can be directly conveyed to the binding machine to begin the binding operation.

Further, in order to swing the support means, an ejecting means is provided, and since the ejecting speed is high at the start of ejecting and decreases thereafter, a predetermined number of collected cut sheets can be cut in a very short time. Not only can it be reversed by transferring it in the rotational direction, but also
The cut sheets no longer shift from each other when they are turned over and dropped.

Further, since the reversing member has a cut sheet I/stosopa formed at the other end facing the cut sheet introducing portion, it is possible to correct the positional deviation of each cut sheet within the reversing member.

Since a pressing means is provided for pressing the stacked cut sheets leaning against one wall of the reversing member, each cut sheet in the stacked state falls down before the reversing operation starts. This eliminates the possibility of misalignment between the cut sheets.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view of a cut sheet conveying device showing an embodiment of the present invention.

In the figure, reference numeral 1 denotes a long packaging sheet folded in half in the width direction, and the packaging sheet 1 is made of transparent cellophane film. On one side, a polyethylene layer is laminated to form half a mirror surface and half a satin surface in the width direction, and the polyethylene layer is folded in half with the polyethylene layer inside, and the outer surface is white suitable for printing. Although the display section is formed in a strip shape with a predetermined width, it is not limited to this, and other appropriately formed display sections can be used.

2: With the folded part facing the bottom, insert the package sheet 1 in the direction of arrow A.
The intermittent transfer member 2 includes a feed roller 3 that supports the upper edge of the packaging sheet 1, and a motor 4 that intermittently drives the feed roller 3.
It is equipped with

The package sheet 1 is heat-sealed at predetermined intervals along the transport direction, so that compartments 5 are formed with the folded portion of the package sheet 1 as the bottom and the top open. ing.

Appropriate drugs, such as powders, are introduced into the compartments 5 by a drug input member, and the upper opening of the sachet sheet 1 is sealed after injection, and the medicine is sealed in each compartment 5. A series of elongated sachet sheets 1 are formed.

Further, the packaging sheet]・1 is the intermittent transfer member 2.
A cutter (not shown) disposed in front of the sheet cuts the sheet 6 vertically into an appropriate number of packages, thereby forming a cut sheet 6.

The force sheets 6 are transferred while being held by the feed rollers 3 of the intermittent transfer member 2 and stacked in the reversing member 7. The reversing member 7 has a cut sheet mounting portion 8 formed with at least a wall 10 on which the cut sheet 6 is placed. The cut sheet 6 is placed on the cut sheet placement section 8.
The cut sheets are sent to the cut sheet stopper 9, and are stacked in a state where they are propped up against the wall 10 of the cut sheet placement section 8.

Reference numeral 11 denotes a holding plate that is swingably supported around a shaft 12, and is intermittently swung to hold the introduced cut sheets 1 and 1.
6 is pressed against the wall 10 to maintain the laminated state until the next cut sheet 6 is introduced.

Therefore, the shaft 12 swings in the direction of arrow B and releases the pressed state when the cut sheets 6 are introduced or when the stacked cut sheets 6 are dropped downward.

Further, a nozzle 13 for ejecting compressed air is provided at a position facing the wall 10 of the cut sheet placement section 8. The nozzle 13 constantly blows out compressed air in the direction of the wall 10 and maintains the stacked state of the cut sheets 6 on the cut sheet placement section 8, similar to the presser plate 11 described above.

Below the reversing member 7 having the above-mentioned configuration, there is provided a conveyance housing 14 for conveying the cut sheets 6 that fall when the reversing member 7 swings to a binding machine (not shown). The transport casing 14 includes a moving member 15 that is open at the top and has a U-shaped cross section and a movable bottom plate, and a moving mechanism 16 that moves the bottom plate using a chain or the like.

The reversing member 7 is supported so as to be swingable in the direction of arrow C. The reversing member 7 can hold the cut sheets 6 in a stacked state at the solid line position. Then, when a predetermined number of cut sheets 6 are stacked and the reversing member 7 rotates and tilts as shown by the broken line, the cut sheets 6 fall onto the moving member 15 in the stacked state and are conveyed to the binding machine. be done.

A stopper 17 is provided to stop the rotation of the reversing member 7 from tilting at a constant angle.

Next, FIG. 2 shows a mechanical diagram of the support means and protruding means for the reversing member 7, and FIG. 3 shows a perspective view of the protruding means.

In the figure, 21 is a shaft that rotatably supports the reversing member 7. Reference numeral 22 denotes a swing plate rotatably disposed about the shaft 21. A rotating disk 25 is disposed at a certain distance from the swing disk 22, and rods 24 are pivotally supported at points m and n on the peripheral edge of each rotating disk 25, respectively. The swinging disc 22 has a larger diameter than the rotating disc 25, and even if the n point of the rod 24 is located at the bottom dead center b of the rotating disc 25, the m point of the rod 24 is at the bottom dead center of the swinging disc 22. As a result, the turntable 25
The rotational motion of the swinging plate 22 is converted into a swinging motion of the swinging plate 22.

The rotary disk 25 is rotatably supported by a shaft 26, and is intermittently rotated by a motor (not shown). For this purpose, a limit switch 27 is provided around the periphery of the rotary disk 250, and upon detection by the limit switch 27, rotation is stopped.

With the above-described configuration, the rotating disk 25 intermittently shifts one rotation, thereby causing the swinging disk 22 to perform one sweeping motion.

For example, when point m of the rod 24 is at position a', n
The point is at position a, and when point m of the rod 24 is at position b', point n is at position b. Therefore, when the rotating disk 25 is rotated at a constant speed, the oscillating disk 22 will move between the above m points and the a' position and the b' position.
It swings back and forth between positions.

Next, a protruding means for protruding the reversing member 7 will be explained.

The swinging plate 22 can swing as the rotary disc 25 performs a rotational movement to give a swinging movement to the reversing member 7 . That is, the rocking plate 22 has a bump 28 protruding from one location on its circumference, and as the rocking plate 22 swings, the bump 28 moves against the wall 10 of the reversing member 7. to hit. Due to this impact, the wall body 10 is pushed forward, and the wall body 10 is tilted as shown by the broken line in FIG.
The upper cut sheet 6 is allowed to fall.

At this time, the impact force caused by the impact is set to be maximum when the reversing member 7 starts rotating, and gradually decrease. That is, when the rotary disk 25 rotates at a constant speed in FIG. 2, the speed at point n of the rotor 24 is within the range ! The directional component connecting the axis 21 and the axis 26 becomes maximum at .

Therefore, it is sufficient to fix the m point of the rod 24 so that the swing plate 22 is placed at the swing start position when the n point of the rod 24 is located in the section ρ.

When the hitter 2B hits the wall 10, the reversing member 7 rotates forward and drops the cut sheet 6 into the transport housing 14, and then returns to the solid line position in FIG. 1 to perform the next cut. It is necessary to prepare for the introduction of Sea 1 and Sea 6. Therefore, as shown in FIG. 3, a spring 30 is stretched between the other wall 29 of the reversing member 7 and the hinter 28.

Note that the present invention is not limited to the above embodiments,
Various modifications are possible based on the spirit of the present invention, and these are not excluded from the scope of the present invention.

For example, in the above embodiment, the cut sheet placement section 8
Although at least a wall 10 for leaning the cut sheet 6 is formed and the cross section is approximately L-shaped, a plate portion protruding forward is provided at the upper end of the wall 10 so that the cross section is approximately U-shaped. Good too.

Due to the U-shaped shape, the compressed air ejected from the nozzle 13 enters the U-shaped groove and spreads evenly upward and downward, making it possible to suppress the force and seat 6 well. It becomes possible.

Further, when the cut sheet placement section 8 has a substantially U-shaped cross section, the plate section at the upper end of the wall 10 is caused by centrifugal force when the stacked cut sheets 6 fall due to the reversal of the reversing member 7. Since it serves to prevent the sheet from flying out straight in the tangential direction, it is possible to further improve the fall of the sheet 6.

Further, the shutter 28 is formed to protrude from a swinging plate 22 provided on the side of the cut sheet placement section 8, and the shaft 21 causes a force to be applied to the cut sheet placement section 8. The rod-shaped tip may extend to the center of the wall 10, and the center portion of the wall 10 may be struck by the rod-shaped tip. In this case, a spring fixing portion is formed to protrude apart from the rounded bumper, and the spring is disposed between the spring fixing portion and the wall 10.

Further, the cut sheet stopper 9 has a structure fixed to one end of the force/tight sheet loading section 8, but the stopping position of the cut sheet 6 can be changed depending on the number of compartments of the cut sheet 6. Alternatively, it may be slidable in the longitudinal direction with respect to the cut sheet placement section 8.

(Effects of the Invention) As described in detail above, according to the present invention, the inverted sheet has a cut sheet placement section in which at least a wall for leaning the cut sheet is formed, and has a cut sheet introduction section at one side end. The reversing member is swingably supported by the supporting means;
The reversing member is placed at a position where the cut sheets can be stacked by leaning against the wall in normal times, and at a position where the stacked cut sheets 1 can be dropped when reversing. It is possible to collect a number of cut sheets and transport them directly to the binding machine to begin the binding process. Therefore, it becomes possible to reduce work costs.

Further, in order to swing the supporting means, an ejecting means is provided, and the ejecting speed is high at the start of ejecting and then decreases, so that a predetermined number of collected cut sheets can be cut in a very short time. Not only can the cut sheets be reversed, but the cut sheets will not shift relative to each other when they are reversed and dropped.

Further, since a cut sheet stomper is formed on the other end of the reversing member facing the cut sheet introducing portion, it is possible to correct the positional deviation of each cut sheet within the reversing member.

Since a pressing means is provided for pressing the stacked cut sheets against one wall of the reversing member, each of the cut sheets 1 and 1 in the stacked state is・It will no longer fall down and cause misalignment of the sheets.
