Description

The tray of shipping goods

Technical field

The present invention relates to be used for the tray of shipping goods and the management system of managing tray.

Background technology

The tray that is used for goods transport etc. has the shape of quadrangle (planar rectangular) usually, and its each side is provided with the fork inlet of fork to be used to transport that inserts fork truck.

The example of above-mentioned rectangle tray comprises, for example, on two sides (two relative edges of rectangle) of all sides (four sides), have the two-way inlet tray of two fork inlets of two forks that can insert fork truck, wherein fork can insert tray from both direction; And the four-way inlet tray that on all sides (four sides) of tray, has the fork inlet, wherein fork can insert tray from four direction.

The tray that is used for goods transport etc. can be transported into or transport with the goods or the product that will distribute, so that promote the transportation of fork truck.In this case, be necessary to manage the tray that is transported into or transports bunker.

According to routine, the tray that is transported into or transports bunker is managed by using manifest.Yet manifest is lost probably between the delivery period in the dispense path of complexity, also is difficult to recognize the unwarranted use of tray.

For avoiding this situation, for example in JP 2003-11973A (after this be called patent and announce 1), a kind of management system has been proposed.In this management system, phs terminal or location information transmission terminal are installed in the tray that is used for shipping goods.Receive base station by identification, and the distance of calculating and base station, can confirm the current location of tray from the electric wave of phs terminal or location information transmission terminal.

For example, in JP 2003-36405A (after this be called patent and announce 2), another system has been proposed.In this system, be transferred to administrator terminal such as the date and time of collecting tray (leasing tray), such information such as tray number of collection by networks such as internet, two-way television communications, in registrar server, set up the tray information database.

Yet patent announces that the problem of 1 described system is, is difficult to guarantee to be installed in the phs terminal on the tray or the power supply of location information transmission terminal.For example, if the terminal energy is 0, communication just can not be carried out.In addition, need time and work to be terminal charge.And, even when identifying the position of tray, can not determine whether tray is effectively used or lost.Patent announces that 2 described systems also have problems, and wherein causes the tray number and the actual inconsistent situation of number that is transported into or transports the tray of bunker that have write down probably such as the requirement of such input information such as the date and time of collecting tray, the tray number of collection.

Also have another management system, wherein the ID label is connected on the tray, from/the ID label is read/rewrites tray information.

Yet, interrogator antenna and ID label (repeater) need mutually in the face of so as from/the ID label that is connected on the tray is read/rewrite information.When being connected with a plurality of ID label on the tray, can be from arbitrary ID tag read information.Yet for the ID label is write information, each ID label needs synchronously (each ID labeling requirement has same information) each other, and this point is difficult to realize.

When only there being an ID label to be connected on the side of tray, no longer require synchronous with other ID label.Yet in this case, when attempting when the tray side relative with the side that is connected with the ID label reads the ID label, self becomes obstacle tray, thus can not from/the ID label is read/rewrite information.

The technology that addresses the above problem discloses in for example JP2002-240955A (after this be called patent and announce 3).In this technology, an ID label (RF label) can be linked the tray side by detachable mode, and the ID label can be located on any one of two sides of tray alternatively.Another technology discloses in for example JP H1O-250730A (after this be called patent and announce 4).In this technology, the ID label with antenna arranges that along a diagonal line of planar rectangular tray antenna is erect.

Yet patent announces in the 3 described technology, behind the position of confirming antenna, the ID labeling requirement link be located at fork truck on the relative tray side of interrogator antenna on.Therefore, need to confirm in addition the position of antenna and the connection of ID label.In the technology of patent announcement 4, the gain of antenna direction feature reduces, and makes and may read improperly/rewrite information.

Summary of the invention

For addressing the above problem, the invention provides a kind of tray that is used for shipping goods, described tray has can directly follow the tracks of the mobile route of tray or the contactless IC tag of this type of information, wherein, and by pitching the tray side (both sides of two-way inlet type that enter the mouth from arbitrary being provided with; And four limits of four-way inlet type) visit contactless IC tag, can be easily and reliably from/described label is read/rewrite information.

The shape of goods transport tray of the present invention is a planar rectangular, is provided with two forks that the fork inlet holds fork truck.The fork inlet is located on two relative sides of tray.Tray also be provided with from have fork inlet from a side of described two sides through hole (after this also abbreviating the through hole that passes two sides as) through another side.Through hole is between the fork inlet.Contactless IC tag is located within the through hole, and is positioned near the centre of through hole length direction.

As mentioned above, tray is provided with through hole, and contactless IC tag places within the through hole.Therefore, through hole is a kind of transmission path that leads to contactless IC tag.By being installed in reading signal or rewriteeing the internal communication of signal via through holes and be delivered to contactless IC tag of interrogator antenna transmission on the fork truck.Therefore, might from arbitrary side of two sides (or four sides) of planar rectangular tray from/contactless IC tag is read/rewrite information.

In addition, contactless IC tag can be located near the middle part of through hole length direction.In this case, be connected in the through hole in-to-in noncontact label that canned data can not have deflection and reliably the arbitrary side from two sides (or four sides) of tray read.In addition, also rewrite information reliably.

In the tray of the present invention, preferably, the inside face of through hole has covered conductive material.

In the tray of the present invention, when the shape of the cross-sectional plane of through hole was rectangle, the length of the arbitrary side of rectangular through-hole should be equal to or greater than λ/2, and wherein λ represents the wavelength of employed frequency between contactless IC tag and the interrogator.

Alternatively, when the shape of the cross-sectional plane of through hole was circle, the radius of manhole should be equal to or greater than λ/3.4, and wherein λ represents the wavelength of employed frequency between contactless IC tag and the interrogator.

In addition, when through hole had the ridged cross-sectional plane, the length of side or the radius of through hole were little in the time of having rectangle or circular cross section than through hole, wherein use identical frequency to compare.

Equally preferably, the area of through hole cross-sectional plane increases to the side of tray from the inside of tray.

inlet

2,2 is located at two sides (two relative edges of rectangle) 1a of tray 1, on the 1b.Described fork can insert tray 1 from both direction (two-way inlet type).

Fork inlet

2,2 centers (center of Width) bilateral symmetric arrangement with respect to loan dish 1.

Tray 1 is provided with along the center extension of tray 1 and is positioned at the through hole of pitching between the inlet 2,23.Through hole 3 passes two side 1a which is provided with the fork inlet, 1b.

Through hole 3 has rectangular cross section.Towards

side

1a, 1b is cumulative at the two ends of through hole 3 for the cross-sectional area of through hole 3.The inside face of through hole 3 has covered the conductive material such as metal.RFID label 4 is contained within the through hole 3.RFID label 4 is located near the middle part of length direction of through hole 3.Should be noted that product/goods information, identifying information (for example pallet sizes, model, tray ID etc.) about being transported on the tray 1 record in the RFID label 4.

In the tray 1 of present embodiment, the through hole of being located between the

fork inlet

2,23 is a kind of transmission paths for RFID label 4.(see Fig. 9 A, RFID label 4 is propagated and be delivered to reading signal or rewriteeing signal of antenna 50 transmission 9B) by through hole 3 by being connected in interrogator 5 on the fork truck.

As mentioned above, RFID label 4 is located near the middle part of length direction of through hole 3.Therefore, no matter the fork of fork truck 100 101 whether from

side

1a or 1b insertion tray 1, can not have deflection and reads the information that is stored in the RFID label 4 that is connected within the through hole 3 reliably.In addition, also rewrite information reliably.

Should be noted that RFID label 4 can be connected on either side surface, top surface and the basal surface within the through hole 3.RFID label 4 can place any position of the length direction of through hole 3.Yet, consider above-mentioned can be from two side 1a, one side 1b any do not have and read the purpose that is stored in the information in the RFID label 4 partially and reliably, RFID label 4 preferably is located near the middle part of length direction of through hole 3.

Existing brief description from/read being connected in RFID label 4 on the tray 1/exemplary method of rewrite information.For example, shown in Fig. 9 A and 9B, the antenna 50 of RFID interrogator 5 is connected near the root of fork 101 of fork truck 100.In this case, the fork that inserts trays 1 when the fork 101 of fork truck 100 enters the mouth 2 the time, can from/the RFID label 4 on the tray 1 is read/rewrite information.

The antenna 50 of interrogator 5 can be connected in the top of support component of the fork 101 of fork truck 100.At tray a plurality of trays 1 of time spent not ..., under 1 situation of piling up, by mentioning tray 1 ..., 1 fork 101 together with fork truck 100, can from/the RFID label 4 on each tray 1 is read/rewrite information.

When empty tray 1 was placed on storage location, canned data can use the RFID interrogator that is located at the tray storage location to read in the RFID label 4.As a result, can read identifying information from empty tray 1, thereby can manage the availability of tray 1.

The example of the concrete numerical value of through hole 3 then will be described.

Under the situation of the tray 1 of Figure 1A-1C, the cross-sectional plane of through hole 3 is rectangles.Therefore, arbitrary side of rectangle need have length lambda/2 or longer (λ: the wavelength of the frequency that the RFID interrogator uses).Reason will be described as follows.

Rectangular waveguide (having rectangular cross section) has the transmission feature of HPF (high-pass filter of the frequency by being higher than preset frequency (fo)).In other words, rectangular waveguide has the character of not transmitting the frequency that is lower than fo.Under the situation of rectangular waveguide, frequency f o is as follows by the side edge length L decision of rectangular waveguide:

Fo* λ=C (C: L=λ/2 light velocity)

Among the embodiment of Figure 1A-1C, the through hole 3 of tray 1 conforms to rectangular waveguide.When the frequency of using as RFID was 2.45GHz, the size of through hole 3 (transverse width) needed wideer than about 61.2mm, so that by through hole 3 transmission frequencies and the label information that reads the RFID label 4 that is connected within the through hole 3.

Therefore, for example, when using the 2.45GHz frequency, arbitrary side of through hole 3 need be equal to or greater than about 62mm, so that the reading signal or rewrite signal of the internal transmission RFID of the through hole 3 by tray 1.

Embodiment 2

As mentioned above, RFID label 4 is located near the middle part of length direction of each through hole 13,13.Therefore, though the fork of fork truck 100 101 whether from side 11a, 11b, 11c or 11d insert tray 11, can not have deflection and read the information that is stored in the RFID label 4 that is connected within the through hole 13,13 reliably.In addition, also rewrite information reliably.

Should be noted that RFID label 4 can be connected on either side surface, top surface and the basal surface within the through hole 13,13.RFID label 4 can place any position of the length direction of through hole 13,13.Yet, consider that above-mentioned can not having from any one side of tray 11 4 side 11a, 11b, 11c and 11d read and rewrite the purpose that is stored in the information in the RFID label 4 partially and reliably, RFID label 4 preferably is located near the middle part of length direction of through hole 13,13.

In addition, in embodiment 2, through hole has rectangular cross section.As reason same among the embodiment 1, arbitrary side of through hole 13 need have length lambda/2 or longer (λ: the wavelength of the frequency that the RFID interrogator uses).For example, when using the 2.45GHz frequency, arbitrary side of through hole 13 need be equal to and greater than about 62mm, so that the reading signal or rewrite signal of the internal transmission RFID of the through hole 13 by tray 11.

Embodiment 3

Fig. 3 A is the front elevation that shows according to the tray of another embodiment of the present invention.Fig. 3 B is its center vertical cross-section.Fig. 3 C is its horizontal cross-sectional view.

Tray 21 shown in Fig. 3 A-3C is characterised in that the through hole 23 with circular cross section is located between the fork inlet 2,2.Other structure is basic identical with the embodiment of Figure 1A-1C.

Tray 21 is provided with through hole 23, and described through hole 23 extends and pass two side 1a of

tray

21,1b along the center of tray 21.Towards

side

1a, 1b is cumulative at the two ends of through hole 23 for the cross-sectional area of through hole 23.The inside face of through hole 23 has covered the conductive material such as metal.

In the tray 21 of Fig. 3 A-3C, through hole 23 has circular cross section.The radius of through hole 23 need be equal to or greater than λ/3.4 (λ: the wavelength of the frequency that the RFID interrogator uses).Reason will be described as follows.

Similar to rectangular waveguide, circular waveguide (having circular cross section) has the transmission feature of HPF (high-pass filter of the frequency by being higher than preset frequency (fo)).Under the situation of circular waveguide, in calculated rate fo, need to relate to the Bessel function, therefore, calculation of complex.Yet frequency f o determines that according to the radius r of circular waveguide the relation between them is expressed as follows:

Fo* λ=C (C: r=λ/3.4 light velocity)

Among the embodiment of Fig. 3 A-3C, the through hole 23 of tray 21 conforms to circular waveguide.When the frequency of using as RFID was 2.45GHz, the radius r of through hole 3 needed greater than approximately 36.0mm is wide, so that by through hole 23 transmission frequencies and the label information that reads the RFID label 4 that is connected within the through hole 23.

Embodiment 4

Fig. 4 A is the front elevation that shows according to the tray of another embodiment of the present invention.Fig. 4 B is its center vertical cross-section.Fig. 4 C is its horizontal cross-sectional view.

Tray 71 shown in Fig. 4 A-4C is characterised in that the through hole 73 with ridged cross-sectional plane is located between the fork inlet 2,2.Other structure is basic identical with the embodiment of Figure 1A-1C.

Tray 71 is provided with through hole 73, and described through hole 73 extends and pass two side 1a of tray 71,1b along the center of tray 71.The inside face of through hole 73 has covered the conductive material such as metal.As the through hole 3 of Figure 1A-1C, towards

side

1a, 1b is cumulative at the two ends of through hole 73 for the cross-sectional area of through hole 73.

As mentioned above, in the tray 1 of embodiment 1, when for example using the 2.45GHz frequency, the length of arbitrary side of through hole 3 need be equal to or greater than about 62mm, so that the reading signal or rewrite signal of the internal transmission RFID by through hole 3.Under the situation of the tray 71 of Fig. 4 A-4C, because through hole 73 has the ridged cross-sectional plane, the length of arbitrary side of through hole 73 can be equal to or less than about 62mm, and reason will be described as follows.

Ridge waveguide, for example the through hole with ridged cross-sectional plane 73 of 4A-4C can have quite low cutoff frequency than the rectangular waveguide of equal length and width dimensions.In other words, when using identical frequency, ridge waveguide can have littler length and width dimensions than those rectangular waveguides.Therefore, if that uses 4A-4C has a ridged cross-sectional plane through hole 73, when the frequency of RFID use is 2.45GHz, the length of arbitrary side of through hole 73 can be equal to or less than about 62mm, so that the internal transmission RFID by through hole 73 reads signal or rewrites signal, and can read the label information of the RFID label 4 that is connected within the through hole 73.The ridged cross-sectional plane of through hole is not only " recessed " shape shown in Fig. 4 A-4C (vertical cross-section, through hole 73), and can be, for example " H " shape shown in Fig. 5 A-5C (vertical cross-section, through hole 83).

Embodiment 5

Fig. 6 A is still the front elevation of demonstration according to the tray of another embodiment of the present invention.Fig. 6 B is its center vertical cross-section.Fig. 4 C is its horizontal cross-sectional view.Fig. 7 is the transparent view of the tray of Fig. 6 A-6C.

The tray 31 of Fig. 6 A-6C and Fig. 7 is provided with two side 1a that pass tray 31, the through hole 3 of 1b, and the vertical through hole 33 that extends between the top board of tray 31 and base plate.Vertical through hole 33 is located near the middle part of planar rectangular tray 31.Tray 31 is characterised in that RFID label 4 is connected near the middle part of the through hole 3 between vertical through hole 33 and the fork inlet 2,2.Other structure is basic identical with the embodiment of Figure 1A-1C.

Under the situation of the tray 31 of present embodiment, when empty tray 31 when the tray storage location is piled up, vertical through hole 33 ..., arrange as shown in Figure 8 according to the order of sequence at 33 middle part.As a result, form the through hole that vertically passes each tray 31 middle parts.This through hole is as a kind of the same transmission path of through hole that resembles between the fork inlet 2,2.In this case, for example, the flat plane antenna of RFID interrogator is set, just might reads to read simultaneously the tray (empty tray) 31 that is stored in accumulation by bottom surface in the tray storage location ..., the information in 31 the RFID label 4.In addition, also can the while rewrite information.Be the direction that reads the RFID label among Fig. 8 shown in the arrow A.

When transporting a plurality of empty trays 31 together by fork truck 100 ..., 31 o'clock, be located at fork truck 100 (see Fig. 9 A, 9B) antenna 50 of the RFID interrogator 5 on can be used for right/from the empty tray 31 of each accumulation ..., 31RFID label 4 read/write information.For example, when tray right/from the hirer lend/when giving back, tray can real-time management.

In addition, for example, by reading information transfer to administrative center, the stock of empty tray can be managed in the concentrated area, improves the Occupation coefficient of tray.

As mentioned above, empty tray can easily be managed, thereby also prevents losing and outflowing of tray.

Under the situation of the tray 31 of present embodiment, vertical through hole 33 portions located therein.Therefore, the RFID label 4 on being connected in tray 31 is owing to defective, when failure and other reasons need be changed, and RFID label 4 can be changed by using vertical through hole 33.

Have as Fig. 6 A-6C and circular cross section shown in Figure 7 if be located at the vertical through hole 33 at tray 31 middle parts, the radius of vertical through hole 33 should be equal to or greater than λ/3.4 (λ: the wavelength of the frequency that the RFID interrogator uses).For example, when the frequency of RFID use was 2.45GHz, the radius r of vertical through hole 33 was greater than about 36.0mm.

Have rectangular cross section if be located at vertical through hole 33, have the λ/2 (λ: the wavelength of the frequency that the RFID interrogator uses) of rectangular cross section.For example, when the frequency of RFID use was 2.45GHz, the length of arbitrary side of through hole should be equal to or greater than about 62mm.

Tray according to embodiments of the invention can be by timber or synthetic resin manufacturing.Because synthetic resin is easy to moulding, the tray of being made by synthetic resin is preferred.

According to the tray of embodiments of the invention, or be two-way inlet type, wherein tray is provided with the fork inlet to hold two forks of fork truck on two side, and described fork can insert tray from both direction; Be the four-way inlet type, wherein tray all is provided with the fork inlet on its all sides (four sides), and described fork can insert tray from four direction.

After this, use the exemplary tray management system of tray of the present invention to be described as follows.

In this example, use the tray 31 of Fig. 6 A-6C and Fig. 7.Suppose to be stored in the RFID label 4 that is connected on the tray 31 such as identifying informations such as pallet sizes, model, tray ID.Suppose that also fork truck 100 is provided with the A as Fig. 9, RFID interrogator 5 shown in the 9B and antenna 50 thereof and transceiver 6.The antenna 50 that should be noted that RFID interrogator 5 is connected near the root of fork 101 of fork truck 100.

The basic structure that is used for the rfid system of tray management with reference to Figure 10 explanation.

The rfid system of Figure 10 comprises above-mentioned RFID interrogator 5 on the fork truck 100 and antenna 50 thereof, above-mentioned RFID label 4 on the tray 31 and antenna 40 thereof etc. of being connected in of being installed in.

RFID interrogator 5 comprises the transporting part 51 that is used to inquire, the receiving unit 52 that is used to read, the transporting part 53 that is used to write and control part 54 etc.RFID label 4 comprises that modulating/demodulating part 41, modulation signal produce part 42, demodulation part 43 and information storage part 44 etc.Antenna 50 and 40 mutual communications that RFID interrogator 5 and RFID label 4 pass through separately.

The rfid system operation is as follows.The fork 101 of fork truck 100 inserts the fork inlet 2 of tray 31.Cause the antenna 50 of antenna 40 basic sides of RFID label 4 to RFID interrogator 5.RFID interrogator 5 passes to RFID label 4 with control signal and non-modulation carrier wave from antenna 50.The wireless signal that RFID label 4 receives from RFID interrogator 4 by antenna 40 decodes the control signal that receives with the understanding data read operation.Obtain such as the information storage part 44 of data from be stored in RFID label 4 such as ID number, tray number and hirers, the data of obtaining from information storage part 44 are with the non-modulation carrier modulation that receives.The signal of gained is to 5 transmission (reflection) of RFID interrogator.The signal that the receiving unit 52 of RFID interrogator 5 (being used to read) receives and demodulation is come from 4 transmission (reflection) of RFID label is with the acquisition desired data.RFID interrogator 5 also transmits the information that will write RFID label 4 from transporting part 53 (being used to write).Institute's information transmitted stores (writing) information storage part 44 into then by demodulation part 43 demodulation of RFID label 4.

Rfid system uses frequency bands such as 125KHz, 13.56MHz and 2.45GHz usually.Unless wireless device (transceiver) uses the frequency band identical with rfid system, rfid system and wireless device can be about the time independent operatings.When rfid system and wireless device all used the 2.45GHz frequency, usually preferably, control rfid system and wireless device did not transmit simultaneously to avoid radio interference.

For example, lease information is handled as follows.The client who wants to lease tray by mode such as phone with lease loan dish company and get in touch.Client leases the content of order and leases company's input by tray.Alternatively, client visits by leasing the website that tray company is managed by modes such as networks, imports them by client oneself on display screen and leases the content of order.The content of order is stored.

The specifying information of tray is by leasing all or part of information that tray company has.Suppose unique number or symbol are appointed as the tray ID of each tray.For example, tray ID is assigned to the tray of new purchase and registers in the master data base.

Wireless device base station 202 is connected to host terminal 201, and has the control part (not shown) that is used to transmit and receive various information.Wireless device base station 202 is transferred to the transceiver 6 of other local explanation in this with canned data in the host terminal 201, and is received from the various information about tray of transceiver 6 transmission.

Fork truck 100 comprises two forks (fork branch) 100 that are used to mention tray 31, as Fig. 9 A, shown in the 9B.The control part (not shown) of transceiver 6 is located in the operating seat of fork truck 100, makes chaufeur can handle control part.In addition, RFID interrogator 5 and antenna 50 thereof are located near near the root middle (middle part that two are pitched between 101,101) of the fork 101 of fork truck 100.Therefore, the fork that inserts trays 31 when the fork 101 of fork truck 100 enters the mouth 2 the time, can from/to being connected in RFID label 4 read on the tray 31.Transceiver 6 is to the various information of wireless device base station 202 transmission about tray.

The forks inlet that inserts trays 31 when fork 101 is so that during fork truck 100 transport pallets, can write RFID label 4 by the antenna 50 of RFID interrogator 5 such as the position information such as (storehouses) of current date, fork truck 100.In addition, can read from the RFID label of tray 31 about tray hirer's information or about giving back the entity information of tray.

Next step will illustrate the management stock and lease the allocation situation of tray and the method for the situation of collection with reference to Figure 12.

At first, the exemplary system of leasing is described, the tray of wherein giving back with lend identical, rent is paid later on.

Step S1: the content that client's tray is leased order deposits host terminal in as rental information.The content of leasing order comprises, for example, the hirer: the A of company, model: the T11 tray, required tray number: 10, the required date: on June 1 12 point, the required rental period: 10 days etc.

Step S2: when transporting the tray 31 that will hire out (for example, the fork 101 of fork truck 100 inserts the fork inlet 2 of trays 31), the RFID interrogator 5 of fork truck 100 reads ID number in the RFID label 4 that is stored in tray 31 etc.The RFID interrogator 5 of fork truck 100 also can write rental information and taxi date in the RFID label 4 of tray 31.

Step S3: the tray ID that the transceiver 6 that links to each other with the RFID interrogator 5 of fork truck 100 will use RFID interrogator 5 to read is transferred to wireless device base station 202.

Step S4: the tray ID that is transferred to wireless device base station 202 deposits host terminal 201 in.

Step S5: when in a position (storehouse) when giving back tray 31 (for example, the fork 101 of fork truck 100 inserts the fork inlet of being given back tray 31), the RFID interrogator 5 of fork truck 100 reads the ID in the RFID label 4 that is stored in tray 31.

Step S6: the tray ID that the transceiver 6 that links to each other with the RFID interrogator 5 of fork truck 100 will use RFID interrogator 5 to read is transferred to wireless device base station 202.

Step S7: the tray ID that is transferred to wireless device base station 202 deposits host terminal 201 in.

Step S8: host terminal 201 compares the rental information of each tray in himself data bank and the tray ID of collection.

Step S9: host terminal 201 according to pallet sizes, model, tray number, lend the date and collect the date and calculate the rent of tray.

According to above-mentioned steps, (for example, the fork of fork truck inserts tray) leases ID number that tray company can read each tray when fork truck moves (transportation) tray.When the fork of fork truck inserts the tray of collecting, lease tray company and also can write about the location information of assembling position (storehouse) and the information on collection date.As a result, might understand the dispense path of each tray and collect the path, make it possible to reality in conjunction with tray and move (transportation) and manage stock, allocation situation and the collection situation of leasing tray.

In addition, for example, when the program that is used for tray rent system before had been stored in host terminal 201, can construct an instantaneous accurate and careful expense system.

Next step illustrates the exemplary system of leasing, the tray of wherein giving back with lend identical, rent is paid in advance.

In this example, suppose that client pays in advance to lease the certain rent of tray company that the amount of money depends on that client leases the content of order.Should be noted that the step in the later example of paying of this routine step S1-S8 and above-mentioned rent is identical, will no longer illustrate.Different part in this example and the above-mentioned example below will only be described.

Process forwards later step S10 or S11 to from above-mentioned steps S8.

Step S10: give back before leasing tray finished in the tray rental period when putting (storehouse) in place when the result of host terminal comparison among the step S8 shows, calculate the rent difference of returning client.Reimbursement can calculate in the fate ratio in the rent of original payment.Alternatively, the ratio in the predetermined rental period that reimbursement can be according to the rules (for example, based on weekly) calculates.

Step S11: give back put in place (storehouse) when leasing tray after finishing in the tray rental period, the rent difference that calculating will be collected in addition from client.

As mentioned above, for example, can effectively be used in the tray management system that the stock of tray, allocation situation, collection situation etc. are leased in management according to the tray of the above embodiment of the present invention.In this tray management system, contactless IC tag (for example, RFID label etc.) is linked on the tray, therefore, can directly follow the tracks of the mobile route of tray, thereby might reduce the work with hand-written manifest of quantitative data input or computing machine.In addition, can accurately follow the tracks of the distribution of tray, thereby might understand that tray is lost or the reason of unwarranted use.Therefore, owing to can discern the personnel that are responsible for allocated phase, for example, might require owing to the not defrayment that tray is lost or unwarranted use causes or the expense of claiming damages.

The present invention can implement by other different form under the situation that does not deviate from its spirit or inner characteristic.The various aspects that the foregoing description is considered only are illustrative, rather than restrictive.Therefore, scope of the present invention is by appended claim rather than be described by the foregoing specification.Change within all and the claims full scope of equivalents and revising all will be included within the scope of claim.
