Description

  The present invention relates to a rewritable medium record information updating method and apparatus for erasing record information of a rewritable medium provided in a reusable transport container in a physical distribution system and writing new record information, and a transport container.

A typical example of using a returnable box in a distribution system is a picking instruction system.
The following devices are known as conventional picking instruction systems.
FIG. 11 is a perspective view showing the overall configuration of the picking instruction system according to the embodiment. Storage shelves 2 having a large number of storage units 1 are arranged along a conveyor line 10. An extraction indicator 4 is provided, and a switch 7 that is operated at the end of the extraction operation is further provided. In addition, an article removal number display 6 is provided at the upper part of the storage shelf 2.

  On the other hand, a bucket (return box) 11 that is a reusable transport container is transported by the conveyor line 10, and an IC card 12 is attached to the bucket 11. The card 12 includes a number assigned to each customer, information on the picking instruction to be given to the operator, information on the direction in which the bucket 11 should be transported, and the like in the system. All the information necessary for transporting the bucket and performing the picking work is stored, and has a function of displaying the information.

  Further, in the vicinity of the conveyor line 10, a read / write device 13 is provided for each storage shelf block including a plurality of storage shelves, and the read / write device 13 stores information on the IC card 12 attached to the bucket 11. For example, it has a function of reading without contacting the card by a signal such as a microwave (ultra-short wave) and writing new information on the card 12 and a function of displaying the information on the card. (Non-contact information reading with such an IC card is referred to as RFID (Radio-Frequency-IDentification).)

  In such a configuration, when the bucket 11 arrives in front of the readable / writable machine 13, the readable / writable machine 13 reads the information on the IC card 12, and the type of article to be put into the bucket 11, that is, the position of the storage unit 1 and The number of articles to be picked from the storage unit can be displayed on the individual takeout display 4 and the takeout number display 6 respectively.

  According to the display, the operator picks the necessary articles, that is, the articles in the storage unit 1 whose individual take-out display 4 is lit, by the required number, that is, the number displayed on the take-out number display 6 and puts it into the bucket 11. However, the worker usually performs a picking operation based on the display on the IC card 12.

When picking is completed, the operator presses the switch 7 attached to the storage shelf 2.
A work completion command is given to the IC card 12 from the readable / writable machine 13, and the IC card 12 moves to display picking information relating to the next article.
When the other individual takeout indicator 4 in the storage shelf 2 is turned on and the article takeout number display 6 displays the number, the operator performs the same picking as described above and repeats this sequentially.

In the system described above, it is possible to read information recorded with an IC card attached to the bucket, but since the operator cannot directly view the contents of the IC card, the label is added to the IC card. Some devices print information (character information) that can be read by the operator.
Also, without using the IC card attached to the bucket in FIG. 11, a barcode (including a two-dimensional barcode) is printed on a label affixed to the basket, and the barcode is read by a barcode reader. There was also a device that analyzed the barcode and handled it.

  As reusable labels, the following are known. (See Patent Document 1) “As a reversible thermal paper using a reversible thermal recording material, for example, a leuco-based rewritable thermal paper using an electron-donating dye precursor has been developed. Color develops when the lactone ring in the molecule opens in an acidic atmosphere, and when the acidic atmosphere is removed, the lactone ring closes and returns to a colorless state. And a reversible developer, which reacts with an electron-donating dye precursor and develops reversibility of color development / decoloration. A phenolic compound having a long-chain alkyl group is used.

  FIG. 12 is a characteristic explanatory diagram of the above-described reversible thermal paper. In this figure, the horizontal axis indicates the temperature, and the vertical axis indicates the color density. As shown by the arrows in this figure, when a reversible thermosensitive recording layer (for example, comprising an electron donating dye precursor and a reversible developer) in a decolored state (A) is heated, both melt and become a colored state (B). When this is rapidly cooled, it solidifies in a state close to the molten state and maintains the solid color state (C). On the contrary, when it is gradually cooled from the molten state (B), the electron-donating dye precursor and the reversible developer are phase-separated to return to the original decolored state (A). Further, in the solid color development state (C), there is a property of transitioning to the original decoloring state (A) when held for a certain time in a temperature region slightly lower than the molten state. This temperature region (a temperature region slightly lower than the melting temperature) is referred to as a “decoloring temperature region”.

Under such circumstances, the present applicant has proposed a device using rewritable media (Patent Document 2). This apparatus uses the above-described label using rewritable thermal paper (rewritable media) and arranges the erasing means and the writing means along the vicinity of the conveyor of the distribution system to which the transport container is transported. Means and writing means are moved toward the rewritable medium affixed to the side surface of the transport container, and these erasing means and writing means convey the old recording information of the rewritable medium and the writing of new recording information. The above is executed continuously.
JP 2002-215038 A JP 2007-76121 A

  However, the conventional reusable transport container has the following problems in the system in which the rewritable medium is provided in the transport container.

  Here, the rewritable media is usually attached to the side wall of the transport container. Therefore, in order to continuously erase old recording information on the rewritable medium and write new recording information on the conveyor, the erasing means and the writing means are pressed against the side wall of the transport container. .

  However, when the erasing means and the writing means are pressed against the side wall of the transport container, the erasing means and the writing means erase old recording information on the rewritable medium and write new recording information due to unevenness or distortion of the side walls. And it turns out that you can't perform well.

  Also, when affixing rewritable media to the side wall of the transport container, it is necessary to increase the price of the rewritable media, such as by providing an adhesive on the back of the rewritable media. When replacing the attached rewritable media, it had problems such as troublesome removal work.

An object (object) of the present invention is to provide a rewritable medium record information updating method capable of rewriting the recorded contents of a rewritable medium provided in a transport container or the like used in a distribution system for shipping, etc., uniformly and reliably, and To provide an apparatus.
Still another object of the present invention is to provide a transport container that allows easy replacement of a rewritable medium and allows good rewriting of the contents recorded on the medium.

In order to solve the above problems, a recorded information update method according to the present invention is provided in the vicinity of a rewritable medium composed of reversible thermal paper capable of erasing and writing predetermined recorded information, and a conveyor of a physical distribution system. Arranged on the rewritable medium, and erases the recorded information recorded on the rewritable medium and writes new recorded information, and the rewritable medium is provided with heat insulation on the surface of the transport container between the rewritable medium and the rewritable medium . Using a reusable transport container transported on the conveyor, and pressing means provided with a restraining member including a cushion member, for erasing and writing information on the rewritable medium. sometimes, the pressing means by the pressing member, the pressing hand and thermal insulating cushioning members of the transport container Via the cushion member, the rewritable media to press the side of the erasing means and writing means, characterized by pressing the transport container on the conveyor (claim 1).

  Thus, by performing the above operation with the cushion member interposed between at least one of the rewritable medium and the transport container and between the transport container and the pressing means, erasing by the erasing means and the writing means is performed. In the writing operation, not only the back surface of the rewritable medium is pressed by the pressing means, but also the erasing means and the writing means can be provided even if the rewritable media is provided with irregularities by interposing a cushion member in the pressing. On the other hand, the rewritable medium can be contacted without unevenness, the erasing means and the writing means can be pressed well against the rewritable medium, and extremely reliable rewriting can be performed.

Further, the recording information update device for rewritable media according to the present invention is recorded on a rewritable media composed of reversible thermal paper that is arranged in the vicinity of the conveyor of the physical distribution system and can erase and write the predetermined recorded information. An eraser and a writing means for erasing the recorded information and writing new recorded information, and a holding member provided with a cushion member are provided, and the rewritable medium is provided with heat insulation on the surface of the transport container between the rewritable medium and the rewritable medium . And a pressing means for pressing a reusable transport container transported on the conveyor, the rewritable medium recording information updating device, wherein the pressing means is configured by the restraining member, and the transport container via the heat insulating property of the cushioning member and the cushion member of the pressing means, said rewrite Bull media to press the side of the erasing means and writing means, characterized in that it is configured to press the transfer container on said conveyor (claim 2).

  As described above, since the pressing unit is configured to press the transport container via the cushion member, the pressing unit only presses the back surface of the rewritable medium during the erasing and writing operations by the erasing unit and the writing unit. In addition, since the cushion member is interposed in the pressing, the rewritable medium can be brought into contact with the erasing means and the writing means without any unevenness, and the erasing means and the writing means can be pressed well against the rewritable medium.

  Furthermore, the rewritable medium recording information updating apparatus according to the present invention is configured by a pressing arm that swings so that the pressing means can press the transport container from the inside to the side where the rewritable medium is provided, The pressing arm includes the cushion member at the tip thereof (Claim 3).

  As described above, the pressing means presses the transport container via the cushion member, and this pressing can be performed from the inside of the transport container, so that the pressing means can be used during the erasing and writing operations by the erasing means and the writing means. Since the cushion member can intervene and press the back side of the wall surface on which the rewritable medium is disposed, the rewritable medium can be effectively brought into contact with the erasing means and the writing means without unevenness.

Further, a transport container according to the present invention is a transport container used in the rewritable medium recording information update device according to claim 2 or 3, wherein the rewritable medium is placed on the heat insulating cushion member on the surface of the transport container. It is provided with the latching means which latches (Claim 4).

  As described above, since the transport container includes the cushion member, the followability corresponding to the unevenness of the rewritable medium itself is increased during the erasing and writing operations by the erasing means and the writing means. Media can be effectively contacted without unevenness.

  Furthermore, since the cushion member can be made of a heat insulating material, when it is made of a heat insulating material, the information can be erased effectively when the information is erased with a hot plate. I can.

  According to such a configuration, at the time of erasing and writing operations by the erasing means and the writing means, the followability corresponding to the unevenness of the rewritable media is increased, so that the rewritable media can be effectively and uniformly applied to the erasing means and the writing means. Not only can it be brought into contact, it is not necessary to rely on adhesives to hold the rewritable media.

Further, the transport container according to the present invention is configured such that the locking means is a frame member surrounding the heat insulating cushion member on the surface of the transport container, and the rewritable media can be inserted freely. (Claim 5).

  According to such a configuration, the followability corresponding to the unevenness of the rewritable medium itself is enhanced during the erasing and writing operations by the erasing means and the writing means, so that the rewritable medium is effectively used evenly with respect to the erasing means and the writing means. The rewritable media can be easily attached and detached.

  Moreover, the transport container according to the present invention is configured such that the rewritable medium on the cushion member is pressed against the locking means by the elastic force of the cushion member.

  According to such a configuration, the followability corresponding to the unevenness of the rewritable medium itself is enhanced during the erasing and writing operations by the erasing means and the writing means, so that the rewritable medium is effectively used evenly with respect to the erasing means and the writing means. It is not necessary to provide a special structure for preventing the rewritable media from falling off.

  The recording information update method and apparatus for rewritable media according to the present invention erases even if there is unevenness in the location where the rewritable media is provided by pressing the cushioning member when pressing from the back side of the rewritable media with the pressing means. In addition, the contact between the writing means and the rewritable medium can be ensured, and the writing and erasing of information can be ensured.

  Further, since the transport container according to the present invention includes a cushion member between the rewritable medium and the transport container, the followability corresponding to the unevenness of the rewritable medium itself is increased during the erasing and writing operations by the erasing means and the writing means. The rewritable medium can be effectively brought into contact with the erasing means and the writing means without any unevenness, and the writing and erasing of information can be ensured.

  With reference to FIG. 1, a recording information update method for rewritable media according to the present invention will be described. FIG. 1 is a diagram showing the concept of the present invention.

Perform a write operation. The transport container 21 is continuously transferred by transport means such as a conveyor 28.
A characteristic feature of the present invention is that cushioning is provided between at least one of the rewritable medium 22 and the transport container 21 and between the transport container 21 and the pressing means 25 when erasing and writing information on the rewritable medium 22. It is to be performed with the members 51 and 52 interposed.

  Thus, when there is a cushion member 52 between the rewritable medium 22 and the transport container 21 or when there is a cushion member 51 between the transport container 21 and the pressing means 25, both the cushion members 51, 52 are In the case where there are simultaneously, by performing the information erasing and writing operation in either case, not only the pressing means 25 presses the back surface of the rewritable medium 22 during the erasing and writing operations by the erasing means and the writing means 24. Therefore, the elasticity of the cushion members 51 and 52 can be appropriately interposed in the pressing, thereby allowing the rewritable medium 22 to flexibly correspond to the erasing unit and the information erasing unit 31 (information writing unit 32) of the writing unit 24. Can be contacted evenly. As a result, information can be written and erased very reliably.

  In addition, the cushion members 51 and 52 are not particularly limited in material, and for example, rubber, synthetic resin (foaming material such as sponge), nonwoven fabric, or the like can be used. In addition, the cushion members 51 and 52 are configured to be arranged at the same time, and by making the elasticity (cushion function) different, the range of the cushion performance can be set widely, and the effect is excellent. it can.

  The embodiment of the recording information updating apparatus for rewritable media according to the present invention will be described below in more detail with reference to FIGS.

That is, the erasing unit and the writing unit 24 are arranged along the vicinity of the conveyor 28 of the physical distribution system to which the transport container 21 is transported, and the information erasing unit 31 for erasing information with the heating roller and the information with the thermal head are written. An information writing unit 32 is provided.
The information erasing unit 31 and the information writing unit 32 are configured to be horizontally movable in an arrow direction (see FIGS. 4 and 5) so as to be pressed against a rewritable medium 22 described later.

In FIG. 4, the arrow indicating the moving direction is shown only in the horizontal direction, but it may be configured to move in the vertical direction according to the position of the rewritable label 22.
In FIG. 4, the information erasing unit 31 and the information writing unit 32 are formed separately, but the information erasing unit 31 and the information writing unit 32 may be integrally formed.

  During the erasing and writing operations by the erasing and writing means 24, the pressing means 25 is provided on the back side of the rewritable medium 22 from the inner side 21 b of the rewritable label 22 (specifically, the transport container 21 corresponding to the back side). It is movable so as to press the inner side surface 21c (see FIG. 3).

In the pressing means 25, an arm 36 is provided on the support frame 23 via a support shaft 35 of the movable means 26 so that the arm 36 can swing up and down, and a holding member 37 having a cushion member 51 at the tip is provided. Yes.
The arm 36 is moved up and down with the support shaft 35 as an axis to move the holding member 37 including the cushion member 51 up and down while drawing an arc (see FIGS. 6 and 8).
The holding member 37 provided with the cushion member 51 is raised in an arc so as to be retreated to the retreat position at the upper part of the transport container 21. On the other hand, the holding member 37 provided with the cushion member 51 is lowered to the pressing position while drawing an arc. The holding member 37 including the lowered cushion member 51 presses the inner side surface 21 c of the transport container 21 corresponding to the back surface of the rewritable medium 22 from the inner side 21 b of the transport container 21.

The movable means 26 presses the inner side 21b of the transport container 21 with the rewritable medium 22 attached to the side surface 21a of the transport container 21 as the transport container 21 on the conveyor 28 approaches the erasing and writing means 24. The holding member 37 provided with 25 cushion members 51 is moved.
That is, the movable means 25 includes a support shaft 35 that is supported by the support frame 23 via a mounting bracket 33 (see FIG. 3) and that can be rotated by the actuator 34. An arm 36 is provided on the support shaft 35.

The movable means 26 rotates the support shaft 35 by driving the actuator 34. By setting the actuator 34 to a non-driving state, the support shaft 35 is held stationary.
According to the movable means 26, the pressing means 25 is held on the upper part of the transport container 21 except during the erasing and writing operations of the recorded information on the rewritable medium 22.
Further, according to the movable means 26, when the erasing and writing operations are performed by the erasing and writing means 24, the holding member 37 including the cushion member 51 of the pressing means 25 is lowered while drawing an arc. Thereby, it is possible to press the inner side surface 21c (see FIG. 3) of the transport container 21 corresponding to the back surface of the rewritable medium 22 from the inner side 21b of the transport container 21 with the holding member 37 provided with the cushion member 51.

Next, the operation of the recorded information update apparatus 20 will be described below with reference to FIGS.
In FIG. 5, the erasing and writing means 24 is held at the standby position, and the pressing means 25 is kept at the retracted position.

With the movable means 26, the pressing means 25 is moved to the inner side 21 b of the transport container 21 as the transport container 21 approaches the erasing and writing means 24. Therefore, the pressing means 25 can be moved automatically.

As shown in FIG. 7, the holding member 37 including the cushion member 51 descends from the retracted position to the pressing position in an arc, and the conveyance container 21 corresponding to the back surface of the rewritable medium 22 from the inner side 21 b of the conveyance container 21. The inner surface 21c is pressed.
Next, the information erasing unit 31 and the information writing unit 32 of the erasing and writing unit 24 are pressed against the rewritable medium 22 by horizontally moving the erasing and writing unit 24 from the standby position as indicated by an arrow.

Here, from the inner side 21 b of the transport container 21 to which the rewritable medium 22 is attached, the inner side surface 21 c of the transport container 21 corresponding to the back surface of the rewritable label 22 is pressed by the holding member 37 provided with the cushion member 51.
Therefore, when the information erasing unit 31 and the information writing unit 32 are pressed against the rewritable medium 22, the rewritable medium 22 is prevented from escaping in a direction away from the information erasing unit 31 and the information writing unit 32.
As a result, the information erasing unit 31 and the information writing unit 32 can be suitably pressed against the rewritable medium 22, and the information erasing unit 31 and the information writing unit 32 can be brought into close contact with the rewritable label 22.

  With the information erasing unit 31 in close contact, the reversible thermosensitive recording layer of the rewritable medium 22 (for example, consisting of an electron donating dye precursor and a reversible developer) is heated well by a heating roller. Therefore, from the colored state C in FIG. 12 to the melted state (B) in FIG. 12, when this is slowly cooled, the electron-donating dye precursor and the reversible developer are phase-separated to the original decolored state (A). Therefore, the old recorded information recorded on the rewritable medium 22 can be erased satisfactorily.

The reversible thermosensitive recording layer (for example, electron donating property) of the label in the decolored state (A) in FIG. When heated (consisting of a dye precursor and a reversible developer), both melt and become a colored state (B).
When this is rapidly cooled, it is solidified in a state close to the molten state and the solid color state (C) is maintained, and new information can be recorded.

In the present embodiment, a heating roller is used as the information erasing unit 31, but a metal plate heated to a specific temperature can also be used.
The information recorded on the rewritable medium 22 by the thermal head of the information writing unit 32 is not limited to characters and symbols but can be various information such as a barcode and a two-dimensional barcode.

As shown in FIG. 8, after the new information is recorded, the information erasing unit 31 and the information writing unit 32 are moved away from the rewritable medium 22 by horizontally moving in the direction of the arrow of the erasing and writing means 24. At the same time, the actuator 34 of the movable means 26 is driven, and the arm 36 is swung upward by the support shaft 35.
The holding member 37 having the cushion member 51 rises from the pressing position to the retracted position while drawing an arc, and holds the pressing means 25 on the upper portion of the transport container 21.
By making it possible to hold the pressing means 25 on the upper part of the transport container 21, it is possible to prevent the transport container 21 from being obstructed when transported by the conveyor 28. Thereby, the conveyance container 21 can be favorably conveyed by the conveyor 28.
