Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to specific embodiments and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

As shown in fig. 1, the present embodiment provides a package management method for an unattended logistics post, which includes the following steps:

s1, judging whether a receiving address of a current package is a receiving range of a current logistics post;

s2, if so, acquiring the weight value, the length value, the width value, the height value and the package information of the current package, and selecting the storage position of the current package according to the weight value, the length value, the width value and the height value;

s3, generating a picking code and sending the picking code to a picking person.

According to the parcel management method provided by the embodiment, whether the current parcel is the receiving range of the current logistics post can be judged under the unattended condition, after the current parcel is judged to belong to the receiving range of the current logistics post, the current parcel is transported and placed at the most suitable storage position according to various parameters of the parcel, and meanwhile, the generated pickup code can be sent to a pickup person.

In addition, the proper storage position is searched by taking the weight value, the length value, the width value and the height value of the current package as conditions, so that the matching degree of the current package and the storage position can be increased, and the waste of the storage space is avoided.

As shown in fig. 2, in this embodiment, determining whether the receiving address of the current package is the receiving range of the current logistics post station includes the following steps:

S201, identifying package information of the current package.

Specifically, a first reader is arranged right above the conveyor belt, a reading area of the first reader faces the surface of the conveyor belt and is used for reading the bar code on the current package and sending package information obtained directly by reading the bar code to a first controller.

Further, the first reader is connected with the first controller, reads the bar code on the package passing through the area below the first reader according to the triggering instruction sent by the first controller, and sends the package information obtained directly by reading the bar code to the first controller.

Further, an object sensing device is provided on at least one side of the conveyor belt in the conveying direction of the package. The object sensing device is connected with the first controller and used for sensing packages and sending sensing information to the first controller.

In addition, before the implementation of step S201, the method further includes:

the logistics personnel place the packages on the conveyor belt in sequence according to a certain time interval. The first reader is used for reading the bar code on the package, and the end face of the logistics mark in the package faces the area above the conveyor belt and faces the reading area of the first reader.

S202, the first controller obtains the receiving address information.

Specifically, the first controller receives the package information sent by the first reader, and extracts the receiving address of the current package from the package information.

Further, after the first controller obtains the package information, the keyword of the receiving address of the current package is extracted from the package information based on a text analysis technology.

Optionally, the keyword of the receiving address of the current package extracted by the first controller includes XX cell, XXX college or XXX residential building.

S203, judging whether the current receiving address belongs to the receiving range of the current logistics post.

Specifically, in the collection range database, whether the collection range database comprises a collection address which is the same as or similar to the keyword of the current collection address is matched, if so, the current package is moved to a waiting area; if not, the current package is moved to the rejection area.

Illustratively, if the key of the current shipping address is XX cell and the collection range database also includes cells of the same name, then it is determined that the current package belongs to the collection range of the current logistics post. Otherwise, the current package is judged not to belong to the collection range of the current logistics post.

S204, moving the current package to a waiting area.

Specifically, after judging that the current package belongs to the collection range of the current logistics post, the conveyor belt moves the current package to the tail end of the conveyor belt, and the first controller controls the transfer mechanical arm to move the current package to the weighing tray, so that the weight of the current package is detected.

S205, moving the current package to the reject area.

Specifically, after judging that the current package does not belong to the collection range of the current logistics post, the conveyor belt moves the current package to the tail end of the conveyor belt, and the first controller controls the transfer mechanical arm to move the current package to a removal area so as to wait for a logistics personnel to take the current package away.

Through steps S201 to S205 in this embodiment, under the circumstance that the current logistics post can be unattended, whether the current package is a receiving range of the current logistics post is determined, and corresponding processing is performed on the current package according to the determination result.

As shown in fig. 3, in this embodiment, obtaining the weight value, the length value, the width value, the height value and the package information of the current package includes the following steps:

s301, obtaining a weight value of the current package through the weighing tray.

Specifically, the weighing tray is connected with the second controller, and when the first controller controls the transferring mechanical arm to move the current package to the weighing tray, the weighing tray can detect the weight value of the current package and send the weight value to the second controller.

S302, obtaining the length value and the width value of the current package.

Specifically, a first TOF depth camera is arranged in an area above the weighing tray, a shooting area of the first TOF depth camera faces the weighing tray and is used for shooting a top depth image of a current package and sending the top depth image to a second controller. After receiving the top depth image, the second controller analyzes the top depth image based on the existing image processing technology, so as to obtain the length value and the width value of the current package.

Further, the first TOF depth camera is connected with the second controller, and shoots a top depth image of the current package according to a trigger instruction sent by the second controller after receiving the weight value, and sends the top depth image to the second controller.

S303, obtaining the height value of the current package.

Specifically, a second TOF depth camera is arranged in the side surface area of the weighing tray, and is used for shooting a side surface depth image of the current package and sending the side surface depth image to a second controller. After receiving the side depth image, the second controller analyzes the side depth image based on the existing image processing technology, so as to obtain the height value of the current package.

Further, the second TOF depth camera is connected with the second controller, and shoots a side depth image of the current package according to a trigger instruction sent by the second controller after receiving the weight value, and sends the side depth image to the second controller.

S304, acquiring package information of the current package.

Specifically, a second reader is arranged in an area above the weighing tray, the reading area of the second reader faces the weighing tray and is used for reading the bar code on the current package and sending the package information obtained directly by reading the bar code to a second controller.

Further, the second reader is connected with the second controller, and reads the bar code on the current package according to the trigger instruction sent by the second controller after receiving the weight value, and sends the read current package information to the second controller.

Through steps S301 to S304 in this embodiment, the second controller may obtain the weight value, the length value, the width value, the height value, and the package information of the current package, respectively, so as to prepare for the operation of matching the current package with the appropriate storage location in advance later.

As shown in fig. 4, in this embodiment, selecting a suitable storage location for a current package according to a weight value, a length value, a width value, and a height value includes the following steps:

S401, listing the current residual bearing value of each conventional goods shelf list in the conventional goods shelf database.

Specifically, the current remaining load bearing value of each conventional pallet in each conventional pallet list in the conventional pallet database is checked to know the maximum weight that each conventional pallet can currently bear.

S402, judging whether the current residual bearing value of the conventional goods shelf is smaller than the weight value of the current package.

Specifically, the current remaining load bearing value of each conventional shelf obtained from each conventional shelf list is compared to the weight value of the current package, respectively, to analyze on which conventional shelf the current package may be expected to be placed.

If the current load bearing value of each conventional shelf is a weight value that does not satisfy the current package, step S403 is executed.

If the current load bearing value of each conventional shelf meets the weight value of the current package, step S407 is performed.

Preferably, the package should be preferentially selected for placement on a conventional pallet, and other pallets than the conventional pallet are selected only if there are no conditions for placement of the current package in each conventional pallet.

S403, searching storage position numbers which accord with the height value, the length value and the width value of the current package in each large package shelf list of the large package shelf database.

Specifically, when the current residual bearing value of each conventional goods shelf is determined to be smaller than the weight value of the current package, the condition that each conventional goods shelf does not have the current package is indicated. At this time, the second controller checks the height value, the length value and the width value of the storage position of each large package shelf in each large package shelf list in the large package shelf database, and compares the height value, the length value and the width value of the current package with the height value, the length value and the width value of each storage position respectively, thereby screening the storage position numbers conforming to the height value, the length value and the width value of the current package.

Preferably, since the overall load bearing capacity of the large package shelf is much greater than that of a conventional shelf, and since the weight and volume of the large package are relatively small in daily packages, the specific gravity value is not required when the current package is selected to be placed on the large package shelf, thus simplifying the operation steps.

S404, associating the proper storage position number with the package information.

Specifically, after the selected storage position number is associated with the package information, the corresponding storage position can be conveniently found according to the package information when the package is fetched.

Further, the package information associated with the deposit location number is preferably a recipient contact phone, a receiving address, a logistics list number of the package, or the like.

S405, modifying the state of the storage position number in the large package shelf list.

Specifically, in the large package shelf list corresponding to the large package shelf, the state of the selected storage position number is changed from the idle state to the storage state, so that the storage position number is noted that the non-picked package is stored in the large package shelf list.

Preferably, in the large parcel shelf list, the idle state of the storage location number is indicated by the numeral "1", and the storage state of the storage location number is indicated by the numeral "0". The second controller can know the current state of the storage position number by looking at the numbers 1 and 0.

S406, conveying and placing the current package at a storage position corresponding to the storage position number.

Specifically, after selecting a proper storage position number, the second controller controls the clamping mechanical arm to place the current package on the weighing tray on the transport vehicle; then, inputting the position coordinates or position numbers of the large package shelf into the transport vehicle, and controlling the transport vehicle to transport the current package to the large package shelf; and then, inputting a storage position number to a shelf mechanical arm in the large package shelf, and controlling the shelf mechanical arm in the large package shelf to place the current package in a storage position corresponding to the storage position number.

Further, in the large package shelf, the storage position numbers are sequentially arranged from front to back according to the numerical sequence, so that the shelf mechanical arm can find the corresponding storage position only according to the storage position numbers.

In addition, after the package is placed at the storage position, the goods shelf mechanical arm automatically moves to the reset position, and meanwhile, the transport vehicle also returns to the reset area according to the navigation map in the transport vehicle.

S407, listing the height value, the length value and the width value of the storage position number in the idle state in a conventional shelf list meeting the weight value requirement of the current package.

Specifically, the height value, the length value and the width value of each storage position number meeting the weight value requirement of the current package are listed, so that the height value, the length value and the width value of the current package can be conveniently compared with each other.

S408, judging whether the height value, the length value and the width value of each storage position number are smaller than the height value, the length value and the width value of the current package.

Specifically, the height value, the length value and the width value of each storage position number are respectively compared with the height value, the length value and the width value of the current package, so that the storage position number meeting the conditions is found.

Further, only when the height value, the length value and the width value are not smaller than the height value, the length value and the width value of the current package, the current storage position number is judged to be the storage position number meeting the condition.

If all the storage positions meeting the weight value condition of the current package do not meet the height value, the length value and the width value of the current package, step S403 to step S406 are executed.

If the storage location numbers meeting the weight value condition of the current package also meet the height value, the length value and the width value of the current package, step S409 is performed.

S409, associating the storage position numbers meeting the requirements with the package information.

Specifically, after the determination in step S408, if it is determined that there are a plurality of storage location numbers that meet the requirement, the second controller may arbitrarily select one of the plurality of storage location numbers for storing the current package. If only one storage position number meeting the requirements is judged, the storage position number is directly selected to store the current package.

After the selected storage position number is associated with the package information, the corresponding storage position can be conveniently found according to any field in the package information when the package is fetched.

S410, modifying the state of the storage position number in the conventional goods shelf list.

Specifically, in the conventional shelf list corresponding to the conventional shelf, the state of the selected storage position number is changed from the idle state to the storage state, so that the storage position number is noted in the conventional shelf list that the non-picked package is already stored.

Preferably, in the conventional pallet list, the idle state of the storage location number is denoted by a numeral "1", and the storage state of the storage location number is denoted by a numeral "0". The second controller can know the current state of the storage position number by looking at the numbers 1 and 0.

S411, the current package is transported and placed at a storage location corresponding to the storage location number.

Specifically, after selecting a proper storage position number, the second controller controls the clamping mechanical arm to place the current package on the weighing tray on the transport vehicle; then, inputting the position coordinates or position numbers of the conventional goods shelves into the transport cart, and controlling the transport cart to transport the current packages to the conventional goods shelves; and then, inputting a storage position number to a shelf mechanical arm in the conventional shelf, and controlling the shelf mechanical arm in the conventional shelf to place the current package in a storage position corresponding to the storage position number.

Further, in a conventional shelf, the storage position numbers are sequentially arranged from front to back according to the numerical order, so that the shelf mechanical arm can find the corresponding storage position only according to the storage position numbers.

In this embodiment, the storage position meeting the requirements is searched by taking the weight value, the height value, the length value and the width value of the current package as the conditions, so that the current package can be placed at the most suitable storage position, the accuracy of package warehouse entry is improved, and the space waste caused when the storage position with a larger space is used for placing the package with a smaller volume is avoided.

In this embodiment, the pickup code is generated at least by a shelf number field, a storage location number field, a date of storage field, a contact phone field for the recipient, a physical distribution number field, and a separator between adjacent fields.

Further, the shelf number field may be a regular shelf number field or a large package shelf number field, and the deposit location number field may be a deposit location number field in a regular shelf or a deposit location number field in a large package shelf.

And after the pickup code is generated, the pickup code is sent to the pickup person according to the contact telephone of the pickup person.

As shown in fig. 5, in this embodiment, after generating a pickup code and sending the pickup code to a pickup person, the method includes: the picking-up and reading terminal reads the picking-up code, and after picking-up, the state of the storage position number in the belonging goods shelf list is modified, and the picking-up and reading terminal comprises the following steps:

s501: the part taking and reading terminal is used for reading part codes.

S502: and analyzing each field information contained in the extracted piece code.

Specifically, after the pickup identification terminal identifies and reads the pickup code, the shelf number field, the storage position number field, the warehouse date field, the contact telephone field of the receiver and the logistics number field included in the pickup code are analyzed through the separator between the adjacent fields.

Alternatively, if the shelf number field is a regular shelf number field, it is determined that the package is placed on a regular shelf. If the shelf number field is a large package shelf number field, it is determined that the package is placed on the large package shelf.

S503, judging whether the goods shelf list comprises specified field information.

Specifically, according to the field information analyzed from the picking code, whether the shelf list comprises a storage position number corresponding to the storage position number is judged.

Illustratively, if the second controller determines that the shelf number field in the pick code is a regular shelf number field, a query is made in each regular shelf list in the regular shelf database.

S504, if the second controller judges that all the goods shelf lists do not include all the field information analyzed by the picking codes, the picking code error is prompted, and the picking operation is finished.

S505, taking out the package in the storage position.

For example, if the second controller queries the corresponding field information in the conventional shelf list, the storage position number corresponding to the field information is extracted, the position coordinates or the position number of the conventional shelf and the storage position number are input into the transport vehicle, and the storage position number is input into the shelf mechanical arm corresponding to the conventional shelf number. The goods shelf mechanical arm takes out the package and then puts the package into the transport vehicle, the transport vehicle transports the package to the clamping range of the pick-up mechanical arm, and the second controller controls the pick-up mechanical arm to place the package at the pick-up opening.

S506, after the acquirer confirms, the state of the storage position number in the belonging goods shelf list is modified.

Specifically, after the pick-up person confirms that the package is correct, the second controller modifies the storage state of the current storage position number represented by the number "0" to the idle state represented by the number "1" in the current shelf list, thereby completing the pick-up operation.

In this embodiment, after the package is removed, the state of the storage location number is modified to the storage state indicated by the numeral "0" so that the second controller can know the state of each storage location number in real time, thereby preparing for the next placement of the package for that storage location number.

As shown in fig. 6, in this embodiment, after generating a pickup code and sending the pickup code to a pickup person, the second controller counts storage time of packages in each shelf, transfers non-picked packages determined to be overtime to an overtime storage area, and sends a new pickup code to the pickup person, including the following steps:

s601, the second controller counts the state duration time of each storage position number in the storage state in each shelf list.

Specifically, when the state of the storage location number indicated by the numeral "1" is modified to the storage state indicated by the numeral "0", the second controller counts the storage state indicated by the numeral "0" from the time of the state modification, thereby counting the duration of the storage location number in the storage state.

S602, judging whether the state duration reaches a preset storage time point.

In order to avoid that each storage position in the conventional goods shelf and the large package goods shelf is always occupied by the stored package, the second controller presets a storage time point for the storage state duration of the storage position.

Specifically, the second controller counts the duration time of each storage position number in the storage state, and judges whether the duration time of each storage position number in the storage state reaches a preset storage time point or not.

Further, if it is determined that the duration of the storage state of the current storage location number does not reach the preset storage time point, step S601 is executed to continuously count the duration of each storage location number in the storage state. If it is determined that the duration of the storage state of the current storage location number reaches the preset storage time point, step S603 is executed.

S603, judging that the package in the storage position number is not taken out after overtime.

Specifically, if it is determined that the duration of the storage state of the current storage location number reaches a preset storage time point, the second controller determines that the package in the current storage location number is a non-picked package after timeout.

S604, transferring the package from the current storage position to a timeout storage area.

Specifically, the second controller searches the storage position number which is in an idle state and is suitable for placing the package in the overtime storage database according to the package information associated with the storage position number. And after finding a proper storage position number in the overtime storage database, the second controller controls the shelf mechanical arm to take out the package in the storage position according to the current storage position number of the package and the shelf number to which the package belongs, and places the package in a transport vehicle waiting on one side of the shelf. The transport vehicle moves to the overtime storage area according to the position coordinates or the position numbers of the overtime storage area, and the mechanical arm in the overtime storage area places the current package in the corresponding storage position according to the storage position numbers input by the second controller.

S605, after generating a new picking code, the new picking code is sent to a picking person.

Specifically, a new pick-up code is regenerated according to the overtime storage area number field, the storage position number field, the storage date field, the addressee contact telephone field, the logistics number field and the separator between adjacent fields, and is sent to the pick-up person.

Further, after the new pick is generated, the second controller also associates the new pick with the old pick. If the new picking code is lost, the current storage position of the package can be queried through the old picking code associated with the new picking code, so that the picking operation is completed.

S606, modifying the state of the storage position number of the non-fetched package judged to be overtime before storage in the goods shelf list.

Specifically, after placing the package that has not been taken out of time in the storage position of the time-out storage area, the second controller modifies the storage state, in which the state of the current storage position number is indicated by the numeral "0", to the idle state, indicated by the numeral "1", in the belonging shelf list, so as to prepare for the storage position number at the next time of placing the package.

In this embodiment, the duration of the storage status of the storage location is timed, so that the second controller can know the storage time of each package in the conventional shelf and the large package shelf conveniently. Updating the packages in the storage locations according to the storage time points facilitates placement of newly-warehoused packages in the appropriate storage locations.
