DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a medicine bag used for delivering a medicine prescribed at a dispensing pharmacy or a hospital pharmacy to a patient, and an apparatus for automatically printing the usage and patient name on the medicine bag without the description. This is a technology related to a medicine bag feeder used for a medical device.

2. Description of the Related Art Conventionally, a technique relating to a medicine bag printing apparatus for automatically printing on a medicine bag is disclosed in Japanese Unexamined Patent Publication Nos. H4-112055 and H4-112056. There is disclosed a technique for performing printing by operating a printer corresponding to a selected medicine bag size in accordance with prescription data. The medicine bag feeder used in the medicine bag printing apparatus is configured to carry out only the surface of the stacked medicine bags by using the frictional force of the conveying roller on the surface of the stacked medicine bags. Is simultaneously pulled into the printer, causing a transport error. As a technology for transporting paper with the same technology, copiers and FA
Although there are feeders used for X, even with the adoption of equivalent technology, pull-in errors occur at a rate of about 10% to 20%. The paper used in copiers etc. is a simple piece of paper. The medicine bag is made of paper and the inside is made of a moisture-proof laminate material. The moisture-proof surfaces are overlapped, and the side of the medicine bag is heat-sealed. Form a medicine bag. The difference between the copy paper and the medicine bag is that the thickness of the bag composed of two sheets increases, and the difference in thickness, weight, and bulk between the sealing surface and non-sealing surface is suppressed, so that the loading thickness is reduced by pressing after loading. Because of the thinness, significant differences such as deterioration of the releasability between medicine bags occur. Also, some large-sized medicine bags have valley-folded sides, and such medicine bags can be filled with a large amount of medicine because the bag swells greatly, but the thickness is centered because the sides are valley-folded. When 250 sheets are loaded, the loaded medicine bags are greatly distorted, and the center of the medicine bags is abnormally thin with respect to the thickness of the side of the medicine bags.

[0003]

As described above, the rate of occurrence of a draw-in error caused by the characteristic of a medicine bag and a draw-in error of a medicine bag feeder are reduced at least as much as a feeder used in a copier or the like in which a plurality of sheets are simultaneously drawn in. Is a major challenge.

[0004]

According to the present invention, a bottom plate of a tension device applied to a loaded medicine bag in a medicine bag feeder transport section is provided.
By receiving the bottom plate levels of the central area of the medicine bag and the side area of the medicine bag at different heights, the vicinity of the surface of the medicine bag on which the medicine bag is loaded becomes substantially parallel, and further, the bottom plate provided for loading the medicine bag. Is used to generate a layer of air between the loaded medicine bags by using the repulsive force of the loaded medicine bags to become the plane of the medicine bags, and to convey the medicine bags in an environment where the loaded medicine bags are easily separated from each other. I did it.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a side view of a medicine bag feeder, in which a bottom plate 3 curved by a spring 2 is pushed up from a bottom in a container of a medicine bag feeder frame 1 by a transfer port, and a medicine bag 4 loaded on an upper portion of the bottom plate 3. Is installed. From the upper part of the medicine bag 4, the medicine bags 4 loaded on the printer are conveyed one by one by a conveyance roller 5 rotated by a motor drive (not shown). An auxiliary roller 21 is provided at a transport port so that the medicine bag 4 pushed up by the spring 2 is not directly transmitted to the transport roller 5,
In the medicine bag loaded on the curved bottom plate 3, the medicine bag gap on the transport side is configured such that the auxiliary roller 21 collects a gap at the center of the medicine bag. Since the transport roller 5 is made of rubber or resin material, the contact bag is soft and has high contact friction, and the medicine bag is discharged along with the rotation of the transport roller. On both sides of the medicine bag 4, the adjustment roller 6 is rotated by rotation of a motor (not shown) so as to carry the medicine bag in a direction opposite to the carrying direction of the medicine bag, and the rotating shaft of the adjustment roller 6 is inclined by about 10 degrees in the carrying direction. It is more effective to attach it. This adjustment roller 6
Are made of the same material as the transport roller 5, and are soft and have high contact friction.

FIG. 2 is a side view of the medicine bag feeder. By providing a projection at a position substantially at the center of the bottom plate 3 in the transport direction, the loaded medicine bag 4 is curved, and the same effect as in FIG. 1 is obtained. be able to. The medicine bag on the surface opposite to the carrying port of the loaded medicine bag is supported by a pressing roller 7 supporting arm 8 for lightly pressing the surface of the medicine bag, and is provided to swing vertically in the medicine bag feeder frame 1.

FIG. 3 is a front view of the medicine bag feeder as viewed from the conveying direction. The bottom plate 3 is configured to be separated into a central area and a side area of the medicine bag, and the bottom plate 3 in the central area is set to be higher. Then, the medicine bag side is folded in, and is suitable for a medicine bag having a structure corresponding to a medicine bag having a large thickness difference between the center of the medicine bag and the side.

The medicine bags 4 taken out one by one from the medicine bag feeder having such a configuration are stacked as shown in the right diagram of FIG. 4. When the medicine bags 4 are stacked on a plane, they become as shown in the left diagram.
At this time, the medicine bag interval a described inside the circle in the detailed view is the interval b
When the loaded medicine bag is curved, although slightly larger than that, and the loaded medicine bag is curved, the gap b generated at this time is further enlarged by the repulsive force of the medicine bag that is to be flattened.

FIG. 5 is a plan view of the medicine bag feeder. The auxiliary roller 21 is provided on the feeder side with respect to the transport roller 5. However, the auxiliary roller 21 may be located on the transport port side of the transport roller 5 or directly below it.

As a means for solving the problem that two or three medicine bags overlap and are discharged when the transport roller 5 is operated, the adjusting roller 6 shown in FIG. As mentioned above, it is effective to apply a load in the direction in which the medicine bag that moves is returned, but this will be described in detail here. When the adjustment roller 6 is rotated at an angle of about 10 degrees in the discharge direction of the medicine bag, the medicine bag side is curved as shown in FIG. 6B, and at the same time, the stacked medicine bags are easily separated and the medicine bag below the surface is ejected. Since the sheet is fed in the direction opposite to the direction, the sheets are almost certainly discharged one by one. Further, as an application example, it has been obtained from the experimental results that a cushion material such as rubber may be set in place of the adjusting roller 5 in the same manner as the adjusting roller and the both sides of the loaded medicine bag may be pressed.

As means for making the effect of the present invention more effective, means for preventing the medicine bag immediately below the medicine bag sticking and moving at the time of the initial movement of the medicine bag retraction is provided as shown in FIG. The rubber 13 which is provided immediately below and rises toward the transport roller exerts a transport blocking resistance on the attached medicine bag, and in this situation, the rubber 1 is moved so that the pressing roller moves from the surface medicine bag to the second medicine bag surface.
Preferably, position 3 is adjusted.

Further, as shown in FIG. 8, it is more effective to provide the rubber 13 so as to extend beyond the line connecting the contact point of the transport roller and the contact point of the next transport roller.

It is most preferable that the pressing member has the following structure. The pressing member is formed of a roller. Further, the pressing roller 7 rotates only in one direction, and a high friction material is applied to the outer periphery of the clutch bearing. When the medicine bag is pulled out by the conveying roller 5 for discharging the medicine bag, the pressing roller 7 is used.
Does not rotate, and a pressing load is applied to the medicine bag.

As shown in FIG. 8, in many situations, the medicine bag 4 on the surface is discharged, and the medicine bag stuck to the discharged medicine bag is prevented from being discharged by the rubber 13 standing up, and is discharged one by one. Conveying rollers 5b, 5
In the prior art, the transport rollers were rotated in the transport direction for both 5b and 5c. However, the present invention rotates the transport rollers 5c in the opposite direction to the transport direction to remove the second medicine bag. The operation of returning to the medicine bag feeder is performed.

FIG. 9 (a) shows a state in which the medicine bag is conveyed while being adhered to the medicine bag carried by the carrying roller 5a, and FIG. 9 (b) shows a state where the second medicine bag has arrived between the carrying rollers 5b and 5c. In (c), while the upper medicine bag is conveyed in the conveyance direction, the lower medicine bag adhered to the lower part is blocked by the rotation of the conveyance roller 5c and returned, and (d) shows a state in which the front medicine bag is taken into the printer. A sensor (not shown) detects that the transport rollers 5a, 5b, and 5c are all reversed. At this time, since the pressing roller 7 rotates according to the surface of the medicine bag, the excess medicine bag is returned to the medicine bag feeder. It is.

[0016]

As described above, according to the present invention, the bottom plate of the tension device applied to the loaded medicine bags in the medicine bag feeder transport unit receives the bottom plate levels of the center area of the medicine bags and the side area of the medicine bags at different heights. By doing so, the vicinity of the loaded medicine bag surface transfer port is made substantially parallel, and furthermore, the bottom plate provided for loading the medicine bags is curved, and the resilience of the loaded medicine bags trying to become a flat surface has Use your power
Since a layer of air is generated between the loaded medicine bags and the medicine bags are transported in an environment in which the loaded medicine bags are easily separated from each other, the stoppage of the printing apparatus due to clogging or the like caused by poor retraction of the medicine bags has been drastically reduced.
