DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a product shipping system provided with a plurality of product loading facilities for loading products such as polyvinyl chloride on a transport vehicle such as a tank truck in the same facility.

[0002]

2. Description of the Related Art Conventionally, in a product shipping system in which a plurality of facilities for loading powdered products such as cement into a transport vehicle are provided in the same facility, and the products are loaded into the transport vehicle entering the facility, petroleum is used. Since it is difficult to control the loading amount by the flow rate as in the case of a fluid product such as that described in JP-A-2-183368, for example, a truck scale shared by a plurality of product loading facilities is installed in the facility as disclosed in Japanese Patent Application Laid-Open No. 2-183368. After measuring the tare weight of the introduced transport vehicle on the truck scale, move the transport vehicle to the corresponding product loading facility, load the product there, and then return the transport vehicle to the truck scale again and weigh it. Measured, and the difference from the previously measured tare weight is grasped as the net loading amount.

[0003] In this type of product shipping system, in order to enable efficient shipping, if there is a vacant product loading facility for handling products to be loaded into the incoming transport vehicle, the transport vehicle is promptly removed. It is important to guide to the product loading facility. However, it is extremely difficult in large facilities to make the operator of the transport vehicle determine which product loading equipment is available, and if this is done while the transport vehicle is in operation, there is a risk of inducing an accident. is there. In addition, it is not a good idea to cause a guide man arranged in the system to grasp the status of the product loading facility and guide the transport vehicle, because it causes a rise in labor costs. Therefore, for example, as shown in Japanese Patent Application Laid-Open No. 4-6088, a monitoring means such as a TV camera for monitoring whether or not there is a standby vehicle in each product loading facility is provided, and the empty state of each product loading facility is determined. A system has been reported in which monitoring is performed unattended and guidance information corresponding to the result is displayed on a display device.

[0004]

The conventional product shipping system has the above-described configuration, but has the following problems.

[0005] Since a plurality of product loading facilities share a truck scale, if a plurality of transport vehicles enter at the same time, even if there is an empty product loading facility, the truck scale waits for a long time. It takes a long time to complete.

If it is determined that the loading amount is insufficient by the weighing after the product loading is completed, it is necessary to return the transport vehicle to the product loading facility and perform the loading operation again, and conversely, it is determined that the loading amount is excessive. If so, it is necessary to move to a predetermined place and return the product once loaded. Then, it is necessary to perform measurement using the track scale again.

In order to unattendedly monitor the availability of each product loading facility for the purpose of guiding the transport vehicle to the product loading facility, a monitoring means such as a TV camera is separately required.

The present invention has been made in view of such circumstances, and a first object of the present invention is to provide a product shipping system that can efficiently load products.

A second object of the present invention is to provide a product shipping system for detecting an empty state of each product loading facility on a truck scale provided in each product loading facility.

A stand-by instruction for notifying the product loading facility as a product loading facility to be waited for is displayed on the display panel, and a transport vehicle waiting for the product loading facility when the product loading facility becomes empty. If there is, an entry instruction to guide the transport vehicle that has been in the waiting state earliest to the empty product loading facility is displayed on the display panel .

[0014] When there are a plurality of assignable product loading facilities and none of them is empty, the higher-level control device determines a product loading facility in which the standby time is minimized based on the current standby state of the transport vehicle. Determine the product loading equipment to be assigned.

Further, a configuration is adopted in which the products are loaded into each of the product loading facilities by pipeline transportation from a manufacturing plant, and the higher-level control device performs the above-mentioned processing based on the product receiving data sent from a manufacturing section through a communication line. The information on the product loading equipment in which the product arrived in the product loading equipment file is updated, and the information is transmitted via a communication line from an inspection department that inspects the products manufactured in the manufacturing plant and transported by the pipeline. Based on the inspection results, the product loading equipment file is updated with information for determining whether or not the product can be shipped to the product loading equipment in which the product has arrived, and further, based on order information sent from the sales department via a communication line. The shipping file is updated.

[0016]

In the product shipping system of the present invention, when a transport vehicle enters a facility, a vehicle identification device provided near the entrance of the facility or the like acquires the identifier of the transport vehicle, and the higher-level control device transmits the identifier of the transport vehicle. By referring to a shipping file holding order information including an identifier, a product brand, and a quantity, the product brand and quantity to be loaded into the transport vehicle are recognized, and the product brand, stock quantity, and inspection pass flag handled by each product loading facility are recognized. A product loading facility that can be assigned to the transport vehicle is determined with reference to a product loading facility file that holds information such as the information.

The control device determines that the product loading facility that can be assigned to the transport vehicle is in an empty state based on the measured value of the truck scale of the product loading facility, and manages the state by the host control device. If the current standby state of the transport vehicle of the product loading facility is no standby transport vehicle, the host controller displays an entry instruction for guiding the transport vehicle to the determined product loading facility on the display panel. .

If the control device of the product loading equipment determines that the product loading equipment that can be assigned to the transport vehicle is not empty, the host control device waits for the determined product loading equipment. A standby instruction to be notified as a product loading facility is displayed on the display panel. When there are a plurality of assignable product loading facilities and none of them are empty,
The host controller determines the product loading facility with the minimum standby time as the target product loading facility based on the current standby status of the transport vehicle, and notifies the product loading facility as a standby product loading facility. The instructions are displayed on the display panel. And
When the product loading facility becomes vacant, an entry instruction to guide the transporting vehicle waiting at the product loading facility to the empty product loading facility is displayed on the display panel.

When the above-mentioned instructions are displayed on the display panel, the driver of the transport vehicle that has entered the vehicle can determine which product loading facility the transport vehicle should enter, and which product loading facility. You can easily know if you should wait at
In addition, during standby, it is possible to know when to enter the corresponding product loading facility.

The transport vehicle that has entered the product loading facility stops on the truck scale provided in the product loading facility, where the products are loaded. At this time, the control device of the product loading facility determines the tare weight of the transport vehicle measured by the truck scale and the filling nozzle of the transport vehicle.

The product loading amount is controlled based on a predetermined correction value corresponding to the weight of the nozzle or the like .

When the transport vehicle having finished loading the product leaves the product loading facility, the control device of the product loading facility causes the measured value of the truck scale to become equal to or less than a predetermined value, thereby loading the product. The equipment is determined to be empty.

Further, when a product arrives at a product loading facility by pipeline transportation from a manufacturing plant and product receiving data including a brand name of the received product is transmitted from a manufacturing section via a communication line, the received product is received. Based on the received data, the host controller updates the information such as the stock amount of the product loading equipment receiving the product in the product loading equipment file. At this time, the inspection pass flag, which is information for determining whether or not the product can be shipped, is set to an uninspected state.
Then, when the inspection result of the product is sent from the inspection department for inspecting the product transported by the pipeline through the communication line, the higher-level control device is based on the result, and if the inspection result is passed, the inspection of the corresponding product is performed. Update the pass flag to pass. This allows the product to be shipped. Further, when order information is sent from the sales department via the communication line, the host controller updates the shipping file based on the order information.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described in detail with reference to the drawings.

First, an outline of a product shipping facility to which the product shipping system of the present invention is applied will be described with reference to FIG.

In the product shipping facility shown in FIG. 1, an antenna 81 is installed near the entrance IN of the facility. The antenna 81 is an antenna for communicating with a data carrier a mounted on a transport vehicle that has entered the facility from the entrance IN like a transport vehicle (tank truck) A.

After passing through the entrance IN, there is a waiting area MP on the left hand side, and the transport vehicles A entering the facility are transport vehicles B and C.
As described above, the vehicle temporarily stops at the waiting place MP.

In front of the waiting area MP, two gates G
And a display panel 7 for displaying an approach instruction and a standby instruction at an easy-to-see place, for example, above each of the gates G1 and G2.
1, 72 are provided.

After passing through the first gate G1, there is a product loading facility 1 at the beginning, and a product loading facility 2 adjacent to the product loading facility. After passing through the second gate G2, there is a product loading facility 3, and a product loading facility 4 is located adjacent to the product loading facility 3. In this arrangement of the product loading equipment, the product loading equipment 2 and 4 are passed through the product loading equipment 1 and 3 because the transport vehicle advances to the target product loading equipment through each gate. However, there is an advantage that a narrow site can be effectively used as compared with a configuration in which one product loading facility is provided for each gate. Of course, depending on the shape of the site, other configurations such as 1 gate / 1 product loading facility, 1 gate / 3 product loading facility, etc. may be adopted.

The product loading facility 1 has a truck scale 11
, Control device 12, antenna 13, and two silos T11,
T12 is the product loading facility 2 with a truck scale 21
And a control device 22, an antenna 23 and two silos T21,
T22 is the truck scale 31 on the product loading facility 3.
, A control device 32, an antenna 33 and two silos T31,
T32 is a truck scale 41 on the product loading facility 4.
And a control device 42, an antenna 43 and two silos T41,
T42, each of which allows loading of up to two types of products.

The antennas 13, 23, 33, 43
Are the truck scales 11 and 12 of each product loading facility 1-4.
An antenna for communicating with a data carrier of a transport vehicle stopped on 1, 31, 41. In addition, each silo T1
Delivery of products such as polyvinyl chloride powder to 1 etc. is performed by pipeline transportation from a manufacturing plant (not shown) by pipeline PL.

The transport vehicle loads products in the product loading facilities 1-4, and then leaves the vehicle in the direction opposite to the entrance as shown by the transport vehicle D. When proceeding along the aisle, it passes in front of the management office 6, where a higher-level control device 61 is installed.
There is a post 68 for receiving inspection sheets. The transporting vehicle having finished loading the product receives the shipping slip and the inspection slip at the filling station 68 and exits the facility from the entrance IN. In addition, the packing house 68
The nearby antenna 62 is an antenna for communicating with the data carrier of the transported vehicle after loading.

FIG. 2 is a block diagram of the product shipping system of the present embodiment, and the same reference numerals as those in FIG. 1 indicate the same parts.

The host controller 61 includes a printer 66 for printing out a shipping slip and an inspection slip, a display 68 for displaying messages and the like to maintenance personnel of the management office 6, a car number file 63, a shipping file 64, Various files (databases) such as the product loading facility file 65 and the control devices 91 and 3
2, 42, 22, 12, 83, and a remote manufacturing department 101 and an inspection department 10 via a communication line 100.
2. It is connected to the sales department 103.

The vehicle number file 63 is a file in which the identifiers (company name and vehicle number ID in this embodiment) of the transport vehicles scheduled to enter the product loading facility are registered in advance.

The shipping file 64 is a file for holding order information. This shipping file 64 is a collection of order information, and each order information includes a shipping date (planned shipping date), a company name, a car number ID, a brand name, and a quantity (the weight of the product to be shipped).

In this embodiment, order information can be registered in the shipping file 64 online from the sales department 103. That is, when order information is sent from the sales department 103 via the communication line 100, the host controller 61 receives it and stores it in the shipping file 64. Similarly, order information can be canceled or changed online.

The product loading equipment file 65 is a file for holding various information relating to each of the product loading equipments 1-4.

The product loading facility file 65 stores data for each of the product loading facilities 1 to 4 and data for each silo existing in the product loading facility.

The product loading equipment data includes a product loading equipment name, a gate number indicating which of the gates G1 and G2 the product loading equipment is located at, and a gate number at which the product loading equipment is located. Sequence information and the like indicating how many product loading facilities are present and at which positions the product loading facilities are located are included.

Further, the data of the product loading equipment includes an empty status indicating whether or not the product loading equipment is empty, an identifier when it is not empty, a transport vehicle having shipping contents being loaded, and Loading vehicle information indicating the current status (such as tare weighing), the identifier of the waiting vehicle when there is a waiting vehicle in the product loading facility, The information includes a waiting vehicle information for holding in a queue whether or not the transporting vehicle has the contents, and a waiting time of the product loading facility.

Here, the calculation of the waiting time is performed by the following algorithm in this embodiment. (1) Each time one new waiting vehicle is generated, the following waiting time is added. Quantity (ton number) × constant T + t1 minute Here, the quantity is the quantity in the order information, and the constant T is, for example, 1 minute. This is because the filling time becomes longer in proportion to the quantity. The time t1 takes into account the time required for auxiliary work before and after filling. (2) Every time the waiting vehicle enters the product loading facility and completes tare weighing (empty vehicle weighing), t2 minutes is subtracted from the current waiting time. (3) When the filling is completed, the quantity × the constant T is further subtracted from the current waiting time. (4) When the filled vehicle leaves the truck scale, t3 is further subtracted from the current waiting time.

Next, the data of each silo includes a silo name,
The information includes the brand of the product stored in the silo, the inspection pass flag, the net stock amount, and the like.

The inspection pass flag is a flag indicating whether or not the analysis value of the product stored in the silo satisfies a predetermined requirement, that is, whether or not the inspection has passed, and can be shipped only after passing the inspection. . That is, in the present embodiment, the products are transported from the manufacturing plant to the respective silos through the pipeline PL, and the manufacturing plant does not have a large-capacity tank for storing the manufactured products or takes a long time to transport. In consideration of this, the pipeline is transported immediately after production. For this reason, the inspection result of a product may come out after a product arrives in a silo. Therefore, an interlock between the shipment and the inspection result is set by the inspection pass flag so that a product that does not pass the inspection is not accidentally shipped. In the present embodiment, a report of the inspection result from the inspection section 102 that inspects the product is transmitted to the communication line 1.
When the inspection result is notified from the inspection department, the host controller 61 operates the inspection pass flag of the corresponding silo in the product loading facility file 65.

The data of the silo includes the stock amount after the allocation. The post-allocation inventory amount indicates the net inventory amount at a certain point in time, but is also an inventory amount that takes into account loading into a standby vehicle that has not yet been loaded.

In this embodiment, the net stock amount and the like in the silo data can be set online from the manufacturing department 101. That is, when product shipping data is sent from the manufacturing department 101 via the communication line 100,
The host controller 61 receives the information and updates the net stock amount and the like of the product loading facility file 65.

Referring again to FIG. 2, the host controller 61

FIG. 5 is a flowchart showing the host controller when a wait time calculation event occurs. FIG. 6 is a flowchart showing an example of processing performed by the host computer 61. FIG.
7 is a flowchart showing an example of a process performed by the control devices 12, 22, 32, and 42 of the product loading facilities 1 to 4, and FIG. The operation of the embodiment will be described.

(1) When a new transport vehicle enters

As shown in FIG. 1, when a new transport vehicle A enters the facility from the entrance IN, the control device 8 shown in FIG.
Under the control of 3, the antenna 81 communicates with the data carrier a mounted on the transport vehicle A, and acquires the identifier (company name, vehicle number ID) of the transport vehicle A. The acquired identifier is transmitted from the control device 83 to the higher-level control device 61, and the higher-level control device 61 starts the processing shown in FIG.

First, the acquired identifier is the vehicle number file 6
3 or not, the product loading equipment file 65
It is checked whether there is any overlap with the loading vehicle information and the identifier in the waiting vehicle information stored in (1). When the vehicle is not registered in the vehicle number file 63, the vehicle is processed as an unregistered vehicle, and for example, information of the fact is output from the upper control device 61 to the display device 68, and overlaps with the identifier in the loading vehicle information and the standby vehicle information. In this case, it is determined that the vehicle number is duplicated, and for example, the current identifier is ignored (S2).

When the check passes in the process S1, next,
It is checked whether or not there is order information including the acquired identifier and the processing date as the shipping date in the shipping file 64 (S3). If there is no such information, the order is processed as no order. 68 (S
4).

If there is order information matching the conditions,
Referring to the data of each silo stored in the product loading equipment file 65, it is checked whether or not there is a silo for storing the product of the brand name in the order information (S5). Then, it is checked whether the inspection pass flag is passed for all such silos and whether the stock amount after allocation has a stock amount corresponding to the quantity in the order information (S6).

If it is determined in step S5 that there is no matching brand silo, or if all the matching silos do not pass the check in step S6, it is determined that there is no allocation silo (S7). Is displayed on the display device 68.

If there is a silo that has passed the check in step S6, it is checked whether there are a plurality of silos that have passed the check (S8). If there is only one silo, that silo is determined as an allocation silo in step S12. .

When there are a plurality of silos, it is checked whether or not the silos extend over a plurality of product loading facilities by the gate numbers of the product loading facilities of the silos in the product loading facility file 65 (S9). If it does not straddle, that is, if the silo is under the same product loading facility, an arbitrary silo is determined as the allocation silo in step S12.

When a plurality of silos extend over a plurality of product loading facilities, it is checked whether or not there is a difference in waiting time by referring to the waiting times of these product loading facilities (S10), and there is no difference. For example, in the process S12, an arbitrary silo is determined as an allocation silo.

If there is a difference in the waiting time, a silo on the side of the product loading facility with the shortest waiting time is selected (S11), and that silo is determined as an allocation silo in step S12.

When the allocation silo is determined, in step S12, the determined allocation silo, the identifier of the current transportation vehicle A, and the contents of the order information are set as one standby vehicle information, and the allocation silo in the product loading facility file 65 is stored. It is stored at the end of the queue in the waiting vehicle information in the data of the product loading facilities owned by the subordinate.

Next, the availability of the product loading facility having the allocation silo this time is checked, and if it is in use, the transportation vehicle A, which has entered this time, is made to stand by for a while in the standby area MP. The standby instruction including the number is displayed on the display panels 71 and 72 of the gate to which the product loading equipment to be standby belongs (S13). When the corresponding product loading facility is empty, an entry instruction is promptly displayed as described later.

Finally, a wait time calculation event indicating that one new waiting vehicle has occurred is issued (S14), and FIG.
Then, the processing of FIG. 4 ends.

In response to the issued wait time calculation event, the host controller 61 starts the processing shown in FIG.
In step S1, the occurrence of a new waiting vehicle is identified, and the current waiting time corresponding to the product loading facility in which the waiting vehicle has occurred is updated (S32). Further, the number of products to be loaded in the waiting vehicle is subtracted from the stock amount after allocation in the data of the allocation silo (S33).

The above processing is performed every time a transport vehicle newly enters a facility.

(2) Guidance of standby transport vehicles

The host controller 61 executes the processing shown in FIG. 6, for example, every 10 seconds.

First, the availability of each of the product loading facilities 1 and 2 belonging to the first gate G1 is checked (S
51). If only the product loading facility 2 on the exit side is vacant or if both are not vacant, the process proceeds to step S59 without issuing an entry instruction. The reason why the entry instruction is not issued when only the product loading equipment 2 on the exit side is empty is because the approach to the product loading equipment 2 is hindered by the transport vehicle at the product loading equipment 1 on the entrance side. is there.

When only the product loading facility 1 on the entrance side is empty, the transport vehicle of the product loading facility 2 on the exit side determines whether or not the tare measurement has been completed. (S5)
2) If the tare measurement has not been completed, the processing S is performed without issuing the entry instruction.
Go to 59. This means that, even if the waiting vehicle enters the product loading facility 1 and is loaded, the transport vehicle of the product loading facility 2 on the exit side may not be departed yet when loading is completed and may be kept waiting. Because. On the other hand, if the tare measurement has been completed, such a problem is small. Then, it is checked whether or not there is a waiting vehicle in the product loading facility 1 on the entrance side (S53), and if so, an entry instruction is displayed on the display panel 71. (S54). At this time, if a standby instruction is displayed on the display panel 71 for the standby vehicle that has issued the approach instruction, the standby instruction is deleted, and subsequent standby instructions are sequentially advanced.

Then, the product loading facility file 65 is updated and the control data is sent to the control device 12 (S57,
S58), and the process proceeds to S59. In the update of the product loading equipment file 65 in this process S57, the operation of transferring the standby vehicle information of the transporting vehicle that has issued the entry instruction this time to the loading vehicle information and changing the vacancy status of the product loading equipment to in use. Is performed. In step S58, control data including the identifier of the transport vehicle permitted to enter, the quantity of loading, the filling silo, and the like are sent to the control device of the product loading facility at the entry destination.

If both the product loading facilities 1 and 2 on the entrance side and the exit side are vacant, it is first checked whether there is a waiting vehicle in the product loading facility 2 on the exit side (S55). An instruction to enter the product loading facility 2 is displayed on the display panel 71 (S
56). Also at this time, if the standby instruction is displayed on the display panel 71 for the standby vehicle that has issued the approach instruction, the standby instruction is deleted and the subsequent standby instruction is sequentially advanced. Next, the product loading facility file 65 is updated and the control data is sent to the control device 22 as described above (S57, S58), and the process proceeds to step S59. If there is no standby vehicle in the product loading facility 2 on the exit side, it is checked whether there is a standby vehicle in the product loading facility 1 on the entrance side (S53), and if not, the process proceeds to step S59.
If so, an instruction to enter the product loading facility 1 is displayed on the display panel 71 (S54), and the product loading facility file 65 is updated and control data is sent to the control device 12 as described above (S57). , S58), and proceeds to processing S59.

In step S59, it is determined whether or not the processing has been completed for all the gates. If not, the above-described processing is repeated for the remaining gates. Therefore, the product loading facilities 3 and 4 of the second gate are processed next to the first gate, at which point the processing of FIG. 6 ends.

By executing the processing as shown in FIG. 6 in a short cycle, if there is a vacancy in the product loading equipment to be allocated to the transport vehicle entering the facility, the gate of the gate to which the product loading equipment belongs is assigned. The entry instruction is promptly displayed on the display panel. In addition, if there is a vacancy in the waiting product loading facility for the transport vehicle that has been waiting at the waiting area without vacancy, an entry instruction is promptly displayed.

(3) Loading of Product The control data including the identifier of the transport vehicle permitted to enter, the quantity of loading, the loading silo, etc., transmitted from the upper control device 61 in step S58 in FIG. Received by the control device of the product loading facility. Hereinafter, a description will be given assuming that the control data is received by the control device 42 in the product loading facility 4.

When the control device 42 receives the control data, it starts the processing shown in FIG. 7, first sets the received control data in an internal register or the like (S71), and
Wait for the result of checking the identifier from (step S72).

When the transport vehicle moves on the truck scale 41 of the product loading facility 4 and stops according to the entry instruction, the data carrier mounted on the transport vehicle is transmitted through the antenna 43 under the control of the control device 91 in FIG. The identifier of the transport vehicle is obtained and transmitted to the host controller 61.

The host controller 61 checks whether or not the transmitted identifier of the transport vehicle matches the identifier of the transport vehicle which has issued the entry instruction to the product loading facility 4, and controls the result. Notify the device 42.

The control device 42 determines the result of this check (S73), and if the identifiers do not match, the operation panel 44
Is displayed to notify the operator of the transport vehicle (S74), and the process is terminated. This prevents loading from an incorrect product loading facility.

If the check result indicates that the identifiers match, the tare weight of the transport vehicle is measured by the truck scale 41 and stored in an internal register or the like (S75). At this time, a wait time calculation event to the effect that the tare weighing has been completed is issued to the host controller 61.

As a result, the process S35 of FIG. 5 is executed, and the waiting time in the data of the product loading facility 4 in the product loading facility file 65 is reduced by t2. At this time, at the same time, the tare status is recorded in the loading vehicle information in the data of the product loading facility 4 in the product loading facility file 65.

Thereafter, the operator sets the filling nozzle for the designated filling silo in the hatch of the transport vehicle. At this time, the limit switch linked to the attachment and detachment of the filling nozzle is operated, and the control device 42 identifies the used filling nozzle, that is, the used silo from the operated limit switch,
It is checked whether or not this matches the filling silo in the control data held in the internal register or the like (S76). If they do not match, a guide message indicating that the filling silo is incorrect is displayed on the operation panel 44 (S77), and the process returns to step S76. This prevents silo selection errors.

On the other hand, when the filling nozzle of the correct silo is set on the hatch of the transport vehicle, the control device 42 executes an automatic filling sequence (S78).

In this automatic filling sequence, the product is filled into the transport vehicle from the filling silo while measuring the weight of the transport vehicle by the truck scale 41, and the measured weight of the transport vehicle satisfies the following equation. It is determined that the filling is completed at the time when the charging is completed.

Measured weight of transport vehicle = Tare weight + Product quantity in control data + α where α is a correction value such as the weight of the filling nozzle and is set in advance.

Next, when the control device 42 finishes filling the delivery vehicle with the product of the filling silo, the control device 42 issues a wait time calculation event indicating that the filling has been completed to the upper control device 61 (S).
79).

As a result, the process S37 in FIG. 5 is executed, and the time corresponding to the quantity × T is subtracted from the waiting time in the data of the product loading facility 4 in the product loading facility file 65.

Thereafter, the control device 42 measures the weight of the transported vehicle again using the truck scale 41, and notifies the host control device 61 of this as a filling actual value (S80). The actual filling value indicates a net loading amount not including the weight of the filling nozzle and the like.

Thereafter, when the operator who finished loading moves the transport vehicle and exits the truck scale 41 of the product loading facility 4, the measured value of the truck scale 41 drops below a predetermined value. The control device 42 determines that the product loading facility 4 has become empty by detecting in step S81 that the measured value of the truck scale 41 has dropped below a predetermined value.

When the control unit 42 determines that the product loading facility 4 has become vacant, it issues a vacancy report wait time calculation event to the host control unit 61 (S82), and terminates the control for the current transport vehicle. .

The host controller 61, which has received the waiting time calculation event of the availability report, executes the process 38 of FIG. 5 to erase the loading vehicle information in the data of the product loading equipment 4 in the product loading equipment file 65. And change the empty state to empty. Further, t3 is subtracted from the waiting time (S39).

Although the operation of the product loading facility 4 has been described above as an example, the same operation is performed in the other product loading facilities 1 to 3.

When the transported vehicle having finished loading stops in front of the filling station 68 of the management office 6, the identifier of the transported vehicle is obtained from the data carrier mounted on the transported vehicle via the antenna 62, and the host control is performed. The device 61 is notified.

[0092] Based on this identifier, the host controller 61
The transport vehicle that has finished loading is identified, a shipping slip and an inspection slip are created from the contents of the shipping file, the actual filling value, and the like, and output from the printer 66. The operator of the transport vehicle uses this shipping slip,
Upon receiving the inspection form, the person leaves the facility from the entrance IN.

The embodiments of the present invention have been described above.
The present invention is not limited to the above embodiments, and various other additions and changes are possible. For example, instead of a data carrier, an operator of a transport vehicle holds an IC card or the like,
The company name, car number, and the like recorded on the C card may be read by a card reader or the like. Further, the arrangement structure of the product loading equipment is not limited to the structure shown in FIG.

[0094]

According to the product shipping system of the present invention described above, the following effects can be obtained.

Since a truck scale is provided for each product loading facility, the product scale does not have to wait for a long time on the truck scale even if there is a space in the product loading facility.
Since the products are loaded while measuring the weight of the transport vehicle in each product loading facility, an accurate amount of the products can be loaded at one time. Therefore, products can be efficiently loaded.

Since the empty state of each product loading facility is detected by the truck scale for each product loading facility, a separate monitoring means such as a TV camera is not required.

[0097] The product loading equipment that handles the products to be loaded on the transport vehicle that has entered the facility is automatically recognized, and the products to be entered into the transport vehicle are determined based on the availability or standby state of each product loading facility. Since the loading equipment and the product loading equipment to be waited for are displayed on the display panel, the operator of the transport vehicle can easily know the destination, and the guiding person in the system can be omitted.

When there are a plurality of allocable product loading facilities and none of them is empty, the product loading facility with the minimum waiting time is determined as the allocation target based on the current waiting state of the transport vehicle. Loading efficiency can be further improved.

[0099] Information on the stock quantity of the product can be automatically set based on the product arrival data sent from the manufacturing section through the communication line.

Since information such as an inspection pass flag for determining whether or not a product can be shipped is automatically updated based on the inspection result sent from the inspection department via the communication line, the inspection result can be promptly reflected on the product loading facility.

Since the shipping file is automatically updated based on the order information sent from the sales department via the communication line, no manual operation is required for updating the shipping file, and the order can be canceled or changed at any time before shipping. be able to.
