Description

The present invention relates to a tray with compartmentalized compartments.

2. Description of the Related Art Conventionally, there is a tray provided with a frame that divides a container into a plurality of compartments. Such a tray can be used for sorting articles by storing different articles in each compartment. There is an operation of picking up various types of small articles such as electronic parts and medicines using such a tray (for example, Patent Document 1).

Picking work consists of, for example, pick-up work in which the target articles are transferred from the stock space to trays according to the instructions, and inspection work in which after a series of pick-up work, it is checked whether the articles are aligned according to the instructions. be. At that time, if the tray is not divided into sections, multiple types of articles will be mixed in the tray, so the operator must re-classify the articles by type in the latter half of the inspection work.

Such a picking operation temporarily mixes the articles that were originally sorted in the stock space in the tray, and it is inefficient to sort them again during the subsequent inspection. Therefore, the picking work is made efficient by preventing articles from being mixed with each other by using the trays in which the storage sections are divided.

By the way, during the picking operation, confirmation as to which articles have not yet been picked is made by checking an instruction sheet or electronically recording. However, in many cases, it is difficult to perform such checks while visually checking the already picked items. may be misidentified.

In addition, for example, when picking drugs, if only the name of the drug is written in the instruction sheet, it is necessary to take out the drug handbook from the pocket of the white coat and examine it in order to check the shape of the drug, which causes extra line of sight movement. work becomes inefficient.

Even in such a case, skilled workers generally have a general grasp of the goods storage location, so if they are given only instructions, they move assuming the pick-up work route so as to minimize the flow line in light of their experience. can. Skilled workers are less wasteful because they can accurately distinguish between similar products. However, for example, when a dispensing pharmacy has a sick patient and temporary support is provided from another store, even if the worker who goes to the support has a lot of experience as a pharmacist, the stock space arrangement at the support pharmacy store is originally Since it is different from the store they belong to, they may have the same difficulty as unskilled workers in picking work. Beginners need a certain amount of time to learn how to arrange the stock space at the facility to which they are assigned, although the length of time varies due to differences in individual abilities.

JP 2017-206317

Picking is often considered a low skill requirement. However, if the stock space arrangement of the goods written in the instruction sheet is not well understood, the worker will walk along useless lines of flow. Also, the efficiency of the work fluctuates greatly depending on the amount of knowledge about the article. Due to these factors, individual differences in work efficiency are large. For example, even a skilled worker at a dispensing pharmacy store will need to newly learn most of the stock space layout if he/she is transferred or works at another affiliated store for temporary support. One solution is to have the same product lineup and layout at all stores, but it is not necessarily realistic. Also, when a complete beginner enters the company, there are a huge number of items to learn, so it takes a considerable amount of time to become proficient. It is extremely difficult to flexibly increase personnel during busy periods.

Therefore, there has been a problem of improving the efficiency of picking and other work of accommodating the trays.

(1) A tray according to the present invention comprises an inner tray section including a transparent bottom section and a frame section that divides the bottom section into a plurality of compartments, an outer tray section that accommodates the inner tray section, and the outer tray section. a sheet disposed between the bottom surface portion of the inner tray portion housed in the tray portion and the outer tray portion and having a display portion on the side of the bottom portion.

According to this tray, the sheet having the display section is arranged between the inner tray section and the outer tray section. If a storage instruction for storing articles in the tray, such as an instruction sheet, is written on the display part, a worker who works with the tray can confirm the storage instruction through the transparent bottom part of the inner tray part. As a result, it is possible to improve the efficiency of the operation of picking and storing the articles in the tray.

(2) In the tray described above, the sheet may have substantially the same dimensions as the bottom portion of the inner tray portion. By doing so, the display portion of the sheet can be confirmed from the entire bottom surface portion of the inner tray portion, and the entire storage space of the tray container can be effectively utilized. As a result, it is possible to improve the efficiency of the operation of picking and storing the articles in the tray.

(3) In the tray described above, the outer tray portion may have a rectangular bottom surface, and the bottom surface may have approximately the same dimensions as the bottom surface portion of the inner tray portion. By doing so, it is possible to prevent the inner tray portion from shifting and moving when the inner tray portion is accommodated in the outer tray portion. Even if picking or other work is carried out while holding the tray, with such a tray, the inner tray portion does not shift and move, so picking or other work can be performed easily. You can work more efficiently.

(4) In the tray described above, the inner tray section may be detachable from the outer tray section. By doing so, the sheets arranged between the inner tray section and the outer tray section can be changed to suit the storage operation. As a result, it is possible to appropriately change the contents of the storage work, so that the storage work such as picking into the tray can be made more efficient.

(5) Picking work instructions may be written on the sheet for each of the sections divided by the frame. By doing so, the articles to be accommodated can be clarified by dividing the trays of the compartmented storage spaces. As a result, since the articles to be accommodated are clarified, it is possible to improve the efficiency of picking and other operations for accommodating the articles in the tray.

(6) The tray according to the present invention includes a rectangular parallelepiped outer tray part with an open top, an inner tray part superimposed on the outer tray and divided into a plurality of compartments, and an outer peripheral wall of the outer tray. and an attachment. According to such a tray, each worker can easily perform the work according to the instructions by attaching the medium on which the information about the contents to be stored in the tray is described to the attachment.

(7) In the tray described above, the outer peripheral wall may have a socket structure to which an attachment can be attached. By doing so, the attachment can be made removable by the socket structure.

(8) In the tray described above, the attachment may be capable of gripping the paper medium with a paper clip. According to such a tray, detailed instructions can be given to each worker by attaching a paper medium instruction sheet to the upper edge of the outer tray portion with the paper holder attachment.

(9) In the tray described above, the attachment may be a mobile terminal holder that can be attached to a socket. According to such a tray, detailed dynamic instructions can be transmitted to each worker by attaching a mobile terminal capable of dynamic display such as a smart phone to the upper edge of the outer tray portion with a holder attachment.

(10) In the tray described above, the socket structure may be attachable with a work support device. According to such a tray, a work support device such as a battery and a sensor can be interlocked with a mobile terminal to easily convey dynamic instructions to each worker.

According to the present invention, efficiency can be improved simply by utilizing the in-tray function that prevents articles from being mixed. Picking workers do not need to change their work flow significantly, so they feel little resistance to using it. Therefore, by using the instruction sheet format and various attachments together, the work can be made more efficient within a range where there is no resistance. The effects of the present invention can be expected to be scalable from small-scale business establishments to large-scale business establishments.

In the tray according to the embodiment of the present invention, an outer tray portion that is held by hand during picking, an inner tray portion that is divided into small compartments that hold articles in a sorted state, and an intray that is laid on the base tray and covered from above. FIG. 4 is a perspective view showing a seat with a display visible through the bottom surface; It is an embodiment of the sheet provided with the display part in FIG. It is a top view in which the address is printed. 2 is a perspective view showing a state in which an attachment for mounting a mobile terminal is attached to the outer tray portion of the tray in FIG. 1. FIG.

A tray 1 according to an embodiment of the present invention will be described in detail with reference to FIGS. 1 to 3. FIG.

The tray 1 includes an inner tray 12 having a transparent bottom portion 121 and a frame portion 122 that divides the bottom portion 121 into a plurality of compartments, an outer tray portion 11 that accommodates the inner tray 12, and an inner tray portion 11 that accommodates the inner tray portion 11. and a sheet 13 arranged between the bottom surface portion 121 of the inner tray 12 and the outer tray portion 11 and having a display portion 131 on the bottom surface portion 121 side. In the following embodiments, the inner tray 12 is also called an intray, and the outer tray section 11 is also called a base tray. The tray 1 functions as a case for storing articles.

The inner tray 12 has an outer peripheral wall portion 123 that forms the outer periphery of the inner tray 12 corresponding to the shape of the outer tray portion 11, and a frame portion 122 that divides the inner tray 12 into a plurality of compartments within the outer peripheral wall portion 123. and each compartment forms a container. In addition, the bottom surface portion 121 of the inner tray 12 has transparency to the extent that when one side is viewed from the other side through the bottom surface portion 121 , display or the like on the other side can be viewed.

In this embodiment, for example, the outer peripheral wall portion 123, the frame portion 122, and the bottom portion 121 are integrally formed of a synthetic resin by injection molding. However, the outer peripheral wall portion 123 and the bottom portion 121 and the frame portion 122 may be formed separately, and for example, the frame portion 122 may be fitted into the outer peripheral wall portion 123 . Also, the inner tray 12 can be made of various materials as long as the bottom portion 121 has a predetermined degree of transparency. That is, for example, the outer peripheral wall portion 123 and the bottom portion 121 and the frame portion 122 may be made of different materials.

The outer tray portion 11 is formed in a rectangular parallelepiped box shape with an open top. Therefore, the outer tray 1 has a rectangular bottom surface 111 . The bottom surface 111 of the outer tray 1 is slightly larger than the bottom surface 121 of the inner tray 12 and has approximately the same dimensions. Further, the peripheral tray 1 is made of paper, for example. The outer tray portion 11 may be made of other material as long as it has enough rigidity to maintain its shape with the inner tray 12 attached to the outer tray portion 11 and predetermined articles accommodated therein.

The outer tray portion 11 has an outer peripheral wall 113 forming a rectangular parallelepiped box shape, and an attachment A such as a holder attachment to which a mobile terminal such as a smartphone can be attached is attached to the outer peripheral wall 113 (see FIG. 3 ). ). The outer peripheral wall 113 of the outer tray portion 11 has a socket structure (not shown), and the attachment A is detachably attached to the upper edge of the outer peripheral wall 113 of the tray 1 .

As is conventionally known, a smart phone attachable to the attachment A is capable of dynamic display, and can display picking instructions and the like to the user of the tray 1 depending on the situation. Also, the attachment A may be a paper clip to which paper such as an instruction sheet can be attached. Also, the outer tray portion 11 can be made of various materials as long as it has the rigidity to maintain its shape.

The sheet 13 is sandwiched between the bottom surface portion 121 of the inner tray 12 and the bottom surface 111 of the outer tray portion 11 and has a display portion 131 that is visible through the transparent bottom surface portion 121 of the inner tray 12 . The display unit 131 can be formed by conventionally well-known printing means such as printing on the sheet 13 with a color printer or pasting a sticker printed with the display content on the sheet 13 according to the display content.

In this embodiment, the sheet 13 has approximately the same dimensions as the bottom portion 121 of the inner tray 12 . However, the sheets 13 may have different dimensions than the bottom portion 121 of the inner tray 12 . Further, in the present embodiment, the display unit 131 (display surface) displays picking work instructions for each section divided by the frame section 122 (see FIG. 2).

The tray 1 is configured by stacking the inner tray 12 and the outer tray portion 11 such that the sheet 13 is sandwiched between the bottom portion 121 of the inner tray 12 and the bottom surface 111 of the outer tray portion 11 . Here, the inner tray 12 and the sheet 13 are each detachable from the outer tray section 11 . However, the inner tray 12 and the outer tray portion 11 are integrally formed, a cut is provided near the bottom surface 111 of the outer tray 1, and the bottom surface portion 121 of the inner tray 12 and the bottom surface 111 of the outer tray portion 11 are separated from the cut. You may insert the sheet|seat 13 so that it may pinch between.

Next, how to use the tray 1 will be described. In the following description, regarding the tray 1, a form in which the present invention exhibits the most effect will be described assuming IT devices that are generally available at present. That is, when using the tray 1 according to the embodiment, conventionally well-known IT devices can be used together.

First, a base tray (outer tray section 11), an intray (inner tray 12), and a color printer are prepared. The color printer may be an ink jet type or a laser type, but a laser type is more suitable for efficiently outputting a highly visible instruction sheet (sheet 13). When the articles to be picked and the respective quantities are determined, the photograph of the shape of each article, the location of the stock space, and the symbol color of the rack or zone of the stock space are printed at the location corresponding to the small section of the intray to which the article is to be transferred. Place the instructions on the base tray as an insole and place the intray on top. At least the bottom of the intray is made of a transparent material, and the name, quantity, location of the stock space, its symbol color, and shape picture of the items to be put in each small compartment are clearly visible on the display part of the sheet. be.

Workers head to an easily accessible stock space and pick up according to the instructions marked on the small compartment. Since the object to be picked in the vicinity can be intuitively recognized by the symbol color, the worker completes the pick-up operation in the vicinity as much as possible. The worker moves to another zone and completes the picking operation there for the picking objects also in the zone. The pick up operation ends when there are no more unfinished zones, ie, no more untransferred intray parcels.

Next, the worker moves on to audit work. The operator removes the intray and places it on the inspection table. It is also easy to take out the instruction book which was put in the insole. After checking the number of items in each small section and confirming that they are in accordance with the instructions, a mark such as a check is specified in the designated column of the instructions. When all parcels are marked with the correct quantity, the audit is completed and the picking operation is successfully completed.

Now, if the stock space is not so large or if the number of workers is as small as 1 or 2, handwritten instructions will work. The instructions may be gripped by a paper clip attachment attached to the base tray. The operator holds the tray 1 with one hand and picks it up with the other hand, putting each article into a separate compartment. In the subsequent inspection work, each item is placed in a separate square for each type, so the inspection work is completed only by checking the quantity.

Conversely, if there are many people working in a very large facility, there is concern that the picking workers will gather in a part of the stock space, resulting in reduced work efficiency and errors. Since this situation includes factors that cannot be predicted at the time the instruction sheet is printed, it is necessary to give dynamic instructions to each worker in addition to static instructions. Detailed dynamic instructions can be conveyed to each worker by attaching a mobile terminal capable of dynamic display, such as a smartphone, to the upper edge of the base tray with a holder attachment. Workers can also provide feedback to the system via mobile terminals when they discover exceptional situations. The mobile terminal can also serve multiple functions such as a slave unit function for indoor positioning. The base tray can also be provided with an auxiliary battery function for a mobile terminal in the form of side wall attachments A as long as the weight distribution of the base tray is not compromised.

When organic EL sheet displays and thin liquid crystal display devices become available in the future, instead of paper-printed instructions, which is currently envisioned, organic EL sheet displays and liquid crystal display devices will be installed in the base tray and in-tray. It is possible to perform the picking operation by dynamically displaying the instruction by sandwiching it between them.

A dispensing pharmacy store will be described as an example of the tray 1 according to the present invention. The receptionist receives the prescription brought into the store. The pharmacist stocks the medicines written in the received prescriptions with generic drug names or representative product names at their own stores and converts them to the corresponding drug names that can be provided. It is assumed that the receipt computer to which the conversion results have been input stores incidental information such as drug stock space locations and drug shape photographs. Grid-like instructions with symbol colors such as stock space racks and zones are printed.

A pharmacist who carries out picking work puts the instruction sheet between the base tray and the intray and moves it to the stock area. The pharmacist starts by picking up any prescribed drug. The pharmacist refers to the symbol color that represents the stock space arrangement, and after picking up as many other drugs to be picked up as possible that are stocked near the drug that has just been picked up, moves to another zone and picks up the drugs to be picked up in that zone. Pick up as much as possible. When the pharmacist finishes picking up all the medicines instructed in this repetition, the pharmacist moves on to inspection work.

The pharmacist places the intray removed from the base tray on the inspection work table and takes out the instruction sheet laid out on the base tray. The quantity of medication in each compartment of the intray is audited and, if correct, marked with a checkmark or other marking in the designated column of the instructions. When the inspection results for all squares are confirmed on the correct sheet 13, the inspection work is completed and the picking work is normally completed.

In the case of small pharmacies, the pharmacist directly appends the name of the equivalent that they have in stock to the received prescription. The pharmacist grips the marked-up prescription with a paperclip attachment attached to the upper edge of the base tray. The pharmacist picks up each drug described in the prescription and transfers it to a separate square, completing the pick-up operation for all the drugs. Next, the pharmacist places the removed intray on the inspection table, confirms that each item and quantity of the prescription is correct, and marks it with a checkmark or the like. The inspection work is completed when the checks for all drugs are completed, and the picking work is normally completed.

Conversely, when there are many pharmacists working in a large-scale pharmacy, if many pharmacists are concentrated in some dispensing shelves, there is concern that work efficiency will decrease and errors will occur. Since this situation includes unpredictable factors at the time of printing the instructions, it is necessary to convey dynamic instructions to each pharmacist in addition to static instructions. Detailed dynamic instructions can be transmitted to each pharmacist by attaching and fixing a mobile terminal capable of dynamic display like a smartphone to the upper edge of the base tray with a holder attachment. If the pharmacist discovers an exceptional event during the picking operation, feedback information can be sent to the system via the mobile terminal. The mobile terminal can also serve multiple functions such as a slave unit function for indoor positioning. The base tray can also be provided with an auxiliary battery function for a mobile terminal in the form of a wall attachment A within a range that does not impair its weight distribution.

When organic EL sheet displays or ultra-thin liquid crystal display devices become available in the future, instead of printing instructions on paper, which is currently assumed, an organic EL sheet display will be placed between the base tray and the intray. It is possible to dynamically guide the picking work by sandwiching and dynamically displaying instructions.

A basic function of physical distribution is to transport specified goods from stock spaces such as warehouses. Aside from on-demand production or complex individual customized products, it is thought that for the time being, uniform products will be manufactured on a line, stocked, and shipped according to demand. Many attempts have been made to robotize logistics. In many cases, existing robot technology can be used to handle items that are large enough to be carried by a forklift or box-shaped items of standard size.

On the other hand, in the case of the dispensing pharmacy mentioned in the example, the final consumer is provided not in units of boxes but in units of capsules or tablets. In addition, packaging forms lack uniformity, and most of them assume manual work. PTP packaging, which is the majority at present, avoids humidity and is easy to count visually, but it does not consider removal by machine. Even this is at the discretion of the manufacturer, and little consideration is given to mechanical detection. In such business conditions and industries that assume only human work, we believe that the situation will continue for the time being where the human eye, which has a wide range of responsiveness, will be used as a sensor for detection and the hand as an actuator.

At present, the packaging cost has been reduced to the limit, and there is no sign of accepting mechanization as an added value that pushes up the cost. On the other hand, humans functioning as sensors and actuators are multifunctional devices and at the same time, devices that generate errors such as prejudice and misreading in percentage units. In actual work, an individual's ability to continue work at the time of returning to the picking work after interrupting the picking work by answering the phone during the picking work, for example, is greatly influenced by the quality of the individual. In addition, if the content of the corresponding phone call causes a great deal of mental stress, the probability of error occurrence increases. There are some assumption errors due to veterans, but in general, multifaceted checkpoints that verify discrepancies with instructions and have redundancy help reduce human errors.

In addition, it is clear that the latter is easier to understand than the instructions that consist only of letters and the instructions that include actual photographs. In any case, it is undeniable that the manager decided that the picking work was easy enough that anyone could do it if he followed the instructions, so that when a mistake occurred, it was the responsibility of the worker. In facilities with clear human resources, this assumption often works. However, in the future, when the mobility of the labor force will increase more than ever, human resources who are good at actively interpreting written information cannot be the only premise.

On the contrary, it is more important than the steps on the system side that even a complete beginner can do some work. In recent years, when the introduction of foreign workers is being considered due to the decrease in young workers, an environment has arrived in which seemingly simple tasks cannot be performed with only character information written in Japanese. It is time to put in place a system that can get the job done if possible. However, even with a large investment in mechanization, it is not currently satisfactory in terms of function and speed, and it cannot be denied that it may result in a situation in which the system becomes rigid.

And if you look overseas, there is a big difference in the level of education, and you may not be able to expect literacy. However, there are many people who want to work. It is important to incorporate them into the workforce in Japan, but it is expected that the domestic needs for healthcare, such as dispensing pharmacies, will follow the current situation in Japan and face the same problems as Japan. Naturally, there is a demand for an easy-to-learn method that has a low introduction cost hurdle, utilizes abundant human resources, and can be expected to improve efficiency and reduce errors. The present invention provides a powerful solution to these problems regardless of national conditions or languages, and at the same time, when it is introduced, it can be used from stationery-like uses to advanced uses.

The tray 1 as described above is composed of a base tray to be held by a picking operator and an intray that partitions the inner cavity into small compartments as basic entities. In addition, it is assumed that printing software and a printing device capable of printing various kinds of information on the articles to be picked are used in combination on portions corresponding to the small compartment bottom portions 121 of the intray.

The base tray provides a flat lumen bottom surface 111 . When removing one piece from a stack of base trays, the negative pressure generated at the time of separation may make the work difficult. In order to prevent this phenomenon, ventilation holes may be provided on the bottom surface 111 or the side surfaces as long as the respective strength and structure are not impaired. The upper peripheral edge is provided with a gripping structure for holding by hand. If the thickness of the base tray in the height direction is small, the upper surface rim structure may be a structure that allows a thumb to be easily put thereon, and a usage method in which the bottom surface 111 is supported from below by fingers other than the thumb may be provided. The upper edge or side wall is for attaching various attachments A, such as a holder for holding documents such as original instructions to be referred to during picking work, and mobile terminals used when linking with electronic systems. A socket for attachment A may be provided.

The intray is sized to fit within the base tray lumen at least to the extent that it has a removable clearance. The intray has a structure that divides the bottom surface of the lumen of the base tray into a plurality of small compartments. It is desirable that the boundaries separating the small compartments have a height that prevents the contents from unintentionally moving to adjacent compartments due to shaking during transportation. On the other hand, it is desired that the opening area is large enough for the depth of the subsection so that it does not become difficult to take out articles during the later inspection work. The material of the intray is not limited, but at least the bottom portion 121 that comes into contact with the instruction sheet during use should have light transmittance and low distortion to the extent that characters and color tones on the opposite side can be clearly identified.

A handwritten item list of picking instructions is available. However, by linking with a computer system, convenience is further improved. For example, in a receipt computer used in a dispensing pharmacy or the like, various information such as a photograph of the shape of a medicine described in an item list is stored in the system as data. In addition, it is easy to associate the address information of the stock space with the article information. In such a system, not only character information but also additional information such as shape pictures and stock space addresses can be retrieved and extracted when generating instructions. Also, by converting the format, it is possible to print out the information of each article in a grid-separated area instead of a simple line-format list.

By matching the size and arrangement of the squares in the printout of the preceding paragraph with the size and arrangement of the small compartments of the intray in the present invention, the picking operator can put the instructions on the bottom surface 111 of the base tray and stack the intray on top of it. The contents of instructions in each section can be clearly visually recognized during actual use. The picker can intuitively know at a glance not only essential information such as the names and quantities of items to be put into each small section, but also shape photographs for confirmation, points of identification from similar items, and stock space addresses. The sizes of the base tray and the intray are not particularly limited, but it is desirable to conform to the paper size that can be output by a general printer. When there are many stock spaces in a large space, the items to be picked can be placed in adjacent racks or neighboring zones by appropriately using symbol colors for each rack or each zone so that the storage location can be intuitively understood. Since it is possible to intuitively recognize the existence of the , the picking can be performed collectively without moving unnecessary flow lines. As a result, wasteful movements are reduced, and the work efficiency of the entire facility can be improved. For the above reasons, it is desirable that the printer be capable of color output.

When operating the tray 1 system of the present invention, the instruction sheet sandwiched between the base tray and the intray is assumed to be output paper from a personal computer printing device up to the preceding paragraph, but the medium of instruction display is not limited to paper. not present. Instructions may be displayed by a thin display device such as electronic paper, a liquid crystal panel capable of dynamic display, or an organic EL sheet.

The top edge of the base tray provides structure for manual gripping. The upper rim of the base tray can have socket structures for mounting various attachments A thereon. For example, a paperclip for holding a paper document with auxiliary information written on it, or a smartphone holder for use with a mobile terminal that dynamically displays instructions, etc., can be considered. By providing the mechanism on the upper edge or outside of the side wall, the base tray can accommodate various attachments A, including device applications that may appear in the future.
