DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cart, apparatus and cart for picking or sorting articles in a warehouse, a factory, and the like, and used for similar operations in factory cart formation.

[0002]

2. Description of the Related Art In an article storage space in a warehouse or a factory, article storage shelves are usually arranged according to a certain rule in order to improve the efficiency of picking and sorting items. Picking or sorting is performed while moving picking or sorting carts, which are carts on which picked articles or articles to be sorted are placed, along such article storage shelves.

[0003] In such a trolley, in addition to an article storage section for storing picked articles, an identification symbol reading apparatus for reading identification symbols attached to articles, article storage shelves, etc., in order to improve the efficiency of picking and sorting operations. There is also known a device provided with electronic devices such as a barcode reader as a device and a display device for displaying information on the contents of picking work.

Further, a bar code reader for reading a bar code put on an article picked by an operator, a balance on which a plurality of articles can be placed, and a weight measured by the scale and the bar code reader are used. There is also known a picking cart provided with a calculating means for calculating the number of articles placed on a balance from the obtained barcode information and a notifying means for notifying an operator of the calculation result.

[0005]

However, carts equipped with electronic devices such as barcode readers and display devices are more expensive than carts not equipped with such electronic devices. It is common to introduce only the minimum number necessary for picking and sorting work in the camps. Therefore, for example, as soon as a series of picking is completed, it is necessary to use the picking cart for the next series of picking. For this reason, after a series of picking is completed, if necessary, after inspecting the goods at the inspection place in the goods storage area, the picking cart is left in the goods storage area, and the goods are loaded onto the truck from this inspection place. In some cases, goods may be transported to the place by hand.

For example, when picking is performed from an article storage shelf facing a relatively narrow passage for a trolley sandwiched between the article storage shelves, a heavy picking trolley that already contains a considerable amount of articles is moved. At this time, care must be taken not to hit the article storage shelf facing the passage. For this reason, some workers may not be able to move the picking trolley in such a narrow passage, place the trolley on a relatively wide passage, and hold the pick-up trolley between the pick-up storage rack and the trolley. Sometimes carry.

Further, depending on the article storage space, the path sandwiched between the article storage shelves may be too narrow to accommodate a relatively large picking cart equipped with a bar code reader and a display device.

In the present invention, for example, when a series of picking is performed, the picking target articles, the number of picked items, and the articles are stored on a display of a terminal, for example, as a display device attached to the picking cart. Display an article storage shelf or the like. This type of picking data (hereinafter referred to as picking data) may be stored in a storage device attached to or incorporated in the terminal, or may be stored in a storage provided in a predetermined location such as an article storage space. The information may be obtained from the computer by wired or wireless communication (radio wave wireless communication, infrared communication, or other optical communication can be used) sequentially or to some extent collectively according to the progress of the picking operation. Instead of using such a display device, a list or the like on which items to be picked or the like are printed may be used.

The operator moves the picking cart and the cart connected to each other by the connecting device to the article storage shelf designated on the basis of the instruction by the display device or the like,
A predetermined number of the specified articles are picked from the article storage shelf.

Here, if the picking cart is already heavy because it has already accommodated a considerable amount of articles, or if the passage facing the designated article storage shelf is narrow, the picking cart and the picking cart are connected. The connection by the connecting device is released, and only the picking cart is moved to the designated article storage shelf while the picking cart remains in the relatively wide passage. Then, the designated article is picked from the storage shelf, placed on the cart, transported to the picking cart, and transferred to the cart. Then, the picking cart and the cart are connected again by the connecting device, and the picking cart and the cart are moved to the next article storage shelf in accordance with an instruction from the display device or the like.

When the picking cart is provided with an identification symbol reading device such as a bar code reader for identifying an identification symbol such as a bar code attached to the article storage shelf or the article itself, the identification symbol is read. The identification symbol is read by the device, and the readability of the picked article can be determined by comparing the read result with data or the like stored in a storage device attached to or incorporated in the identification symbol reader. The result of this determination may be notified to the worker by a notifying means such as a buzzer, or at this time, may be simply stored in a storage device or the like, and the stored data may be used for a subsequent re-picking instruction or the like. good.

In the picking, the picking cart includes a weight measuring device, and storage means for storing single item weight data of articles to be picked or sorted.
In the case where there is provided calculating means for calculating the number of articles to be measured using the measurement result of the measuring instrument and the data of the storage means, the picked articles of the designated number are placed on the weight measuring instrument. The total weight is measured, and the number of picks can be calculated by dividing the total weight by the single item weight data of the picked article stored in the storage device attached to or incorporated in the weight measuring device. The result of this calculation may be used to determine whether or not there is a match with the number of picking instructions in the picking data stored in the storage device. If there is no match, the operator may be notified by a buzzer or other notification means. At this point, the data may be simply stored in a storage device or the like, and this stored data may be used for a re-picking instruction later.

Furthermore, in this picking, the picking cart includes a weight measuring device, a storage device for storing single item weight data of the article to be picked or sorted, a measurement result of the measuring device and data of the storage device. If it is provided with a discriminating means for judging the suitability of the article related to the measurement, the article picked by the indicated number is placed on a weight measuring device to measure the total weight, and the measured total weight and The suitability of the picked article (whether there is a difference between articles) can be determined using the single item weight data of the picked article stored in the storage device attached to or incorporated in the weight measuring device. This judgment is made as to whether or not a value obtained by dividing the measured total weight by the single item weight data becomes an integer (if it is an integer, it can be presumed that there is no difference between articles), and the integer matches the indicated number. It can be determined based on whether or not (if it matches, it can be estimated that there is almost no difference in articles), or whether or not a value obtained by dividing the total weight by this integer matches the single item weight data.

The picking proceeds as described above, and when a series of picking is completed, if necessary, inspection is performed at an inspection shop, and then the picking cart and the cart are used for the next series of picking. Here, the picking cart may be used as it is for transporting the articles from the inspection station to the delivery station. In this case, the connection by the connecting device is released to separate the picking cart and the picking cart, and another picking cart is connected to the separated picking cart, which can be used for the next series of picking. . And in this invention, the said connection apparatus
However, the cart and the cart can be integrally changed in direction.

A plate-like work table 5 whose left and right ends are fixed near the upper sides of the left and right frames 4 and 4 and held horizontally,
An article storage box 6 whose left and right ends are fixed to the left and right frames 4 and 4 below the fixed position of the worktable 5 is provided.

The frames 4, 4 are composed of a fixed frame 4a having a lower end fixed to the lower support 3, and a movable frame 4b having a lower end mounted on the fixed frame 4a so as to be vertically adjustable. Has become. For example, the upper end of the movable frame 4a is hollow, and a support shaft 8 having a knob 7 and having a threaded peripheral surface is attached to a hole formed in the peripheral wall of the hollow portion. On the other hand, the lower end of the movable frame 4a can be inserted into this hollow portion,
A plurality of internally threaded holes 4c into which the screws of the support shaft 8 are screwed are formed in the insertable portion so as to be arranged vertically. Thus, the movable frame 4a can be fixed by screwing the support shaft 8 into the corresponding hole 4c in a state where the movable frame 4a is positioned at the height of the worker. In this way, instead of allowing the entire worktable 5 to be vertically adjustable, it is particularly preferable that the electronic device, for example, only the display 9, for which the position is adjusted to the height of the worker in terms of work efficiency, be moved relative to the worktable 5 It may be mounted so that the vertical position can be adjusted. The upper sides of the frames 4, 4 serve as handles 4d for pushing and moving the picking cart 1.

The work table 5 has a terminal device 10 having a display 9 composed of a liquid crystal panel or the like as a display device on its upper surface, a handy scanner 11 as a reading device connected to the terminal device 10, and A wireless communication device 12 connected to the terminal device 10 is provided. A printer 13 as an output device connected to the terminal device 10 is attached to the lower surface side. Further, a weight measuring device connected to the terminal device is also attached to the work table 5, and a mounting portion 14 on which a plurality of articles to be measured by the weight measuring device can be mounted is provided on the upper surface of the work table 5. (See FIG. 1D). These electronic devices will be described later in detail.

The article storage box 6 has an opening at an upper portion. The work table 5 is provided with a sufficient input space 6a between the article storage box 6 and the work table 5 so that articles can be easily stored therein. It is attached to the left and right frames 4 and 4 apart from it.

The picking cart 1 includes:
As shown in FIG. 2A, for example, an unloadable connecting device 21 for connecting an article mounting plate 20a and a picking cart 20 having wheels 20b attached to four corners of its lower surface so as to be freely changeable direction is provided. Have. Illustrated coupling device 21
The mounting plate 22 is attached to the lower support 3 as shown in FIG.
And a stepping arm 24 fixed to the rotating shaft 23, and a connecting member 27 also fixed to the rotating shaft 23. The stepping arm 24 is formed of a material that can be bent in the left-right direction, has a free end extending to the front outside of the lower support 3 and has a stepping portion 24a formed at the end. One end of a spring 25 that pulls up and biases the free end side upward is locked. In order to allow such a downward swing of the stepping arm 24, a notch is formed in the lower support base 3 so that the arm 24 can pass when the stepping arm 24 is stepped down and rocked downward. Are formed. In order to allow the spring 25 of the stepping arm 24 to swing upward in a certain range, a notch 28a having a certain length in the vertical direction is formed in the front side concealing plate 28 attached to the left and right frames 4. And the lower support 3
A lock member 26 for preventing the spring 25 from lifting the stepping arm 24 upward is fixed to the lower support 3 so as to protrude into the notch. The connecting member 27 has a free end extending to the rear side bent upward to engage the engaging portion 27 with the picking cart 20.
a.

In the example shown in the figure, the article mounting plate 20a is used to ensure the engagement with the engaging portion 27a of the connecting member 27 with the picking cart 20 as shown in FIG.
An engagement block 29 protruding downward is fixedly provided on the lower surface of the head. The width of the picking cart 1 in the left-right direction and the front-rear direction is relatively small and is set to be narrower than those of the picking cart 20 so that the cart can be easily moved even in a relatively narrow passage sandwiched between the article storage shelves. I have.

Here, in the illustrated connecting device 21,
When the picking cart 1 and the picking cart 20 are connected, as shown by a broken line A in FIG.
2A, the back portion of the picking cart 1 is brought close to the picking cart 20 in the state where a is highest, and the connecting member in the lowermost position on the back side of the lower support 3 is shown. A block 29 in which the engaging portion 27a is fixed to the article mounting plate 20a of the picking cart 20
Pass underneath. Then, the operator steps on the step portion 24 a of the stepping arm 24 and the locking member 24.
For example, the stepping arm 2 on the left side in FIG.
While bending the arm 4, the arm 24 is moved to a position where the arm 24 has passed through the notch of the lower support 3. After that, the foot part 24
And the foot step arm 24 pulled up by the spring 25 is locked to the lock member 24. In a state where the foot arm 24 is locked by the lock member 24,
As shown in FIG. 2A, when the picking cart 1 is moved in a direction away from the picking cart 20, the engaging portion 27 a of the connecting member 27 engages with the back end face of the block 29 of the picking cart 20. Thus, the picking cart 20 can be moved integrally. In this state, even when the picking cart 1 is moved in the opposite direction, for example, as shown in FIG. 2A, the fixed frame portion 4a of the picking cart 1 The picking trolley 20 can be moved integrally by contacting the end of the plate 20a. Furthermore, picking cart 1
When the moving direction of the connecting member 27 is changed, the connecting portion 27a of the connecting member 27 and the block 29 are engaged with a certain width, and the left and right fixed frame portions 4a are in the width direction of the ends of the article mounting plate 20a. Since the abutments come into contact with different portions, the direction of the picking cart can also be changed integrally. When disconnecting the picking cart 1 and the picking cart 20,
FIG. 2 (c) shows the stepping portion 24a of the stepping arm 24, for example.
The arm 24 is moved to the middle left side to bend from the lock member 26 while bending the stepping arm 24, and the arm 24 is pulled up by the spring 25. As a result, the connecting portion 27a of the connecting member 27 is released to the lowest position where it does not engage with the block 29 to release the connection. By separating the picking cart 1 from the picking cart 20 in this disconnected state, both can be moved independently.

Instead of the connecting device 21 using the connection and disconnection by the stepping operation of the stepping arm 24 as described above, an electric connecting device 21 as shown in FIG. 2A may be used. The illustrated electric coupling device 21 includes the coupling member 2.
And an actuator such as a solenoid (not shown) for swinging the pickup 7 and a picking cart 2
0, based on a signal from the sensor 30 for detecting contact or proximity with the end of the article mounting plate 20a,
And a control unit (not shown) for controlling the actuator. The control unit controls the actuator, for example, as follows. That is, the actuator is driven to move the connecting member 27 to the most lowered connection releasing position by a signal from a worker operation switch for issuing a connection release instruction (not shown). When the sensor 30 detects the contact or proximity of the picking cart 20 to the end of the article mounting plate 20a, the actuator is driven to move the connecting member 27 to the highest connecting position. According to this, the connecting operation can be automatically performed by bringing the picking cart 1 close to the picking cart 20.

The picking cart 1 shown in FIG.
Includes a motor 31, a drive transmission mechanism (not shown) for transmitting the drive of the motor to the wheels, a control unit (not shown) for the motor and the drive transmission mechanism, and a travel instructing device by an operator. A riding step 32 having two wheels 33 is foldably mounted as shown. (Hereinafter, margin)

Further, instead of connecting the block 29 and the connecting member 27 by mechanical engagement as in the above-described connecting device 21, the block 29 and the connecting member 27 may be connected electromagnetically using an electromagnet or the like. Further, such a connecting device 21 may be fixedly attached to the picking cart 20 instead of being fixedly attached to the picking cart 1.

Next, electronic equipment such as the terminal 10 will be described in detail. FIG. 3 is a block diagram of the electronic device. The terminal device 10 has a built-in computer having an information processing function. The CPU 39 of the computer has, in addition to the display 9, the printer 13, the wireless communication device 12, and the weight measuring device 40, a notification device provided as necessary. Are connected via an interface (not shown). Here, the wireless communication device 12 is for performing data communication with an information processing device 42 disposed in a picking place or the like. Also, this CPU 39
A storage device 43 for storing a program for controlling operation of an electronic device, which will be described later, and picking data transmitted by communication from the information processing device 42 is also connected thereto.

Next, a picking operation using the picking device having the above-described configuration and an operation of the picking device will be described with reference to FIGS. FIG. 4 is a flowchart of control in the information processing apparatus, and FIG.
It is a flowchart of the control in PU39. First, as a prerequisite for using this picking device, a code for identifying each of the various types of articles stored in an article storage shelf of a warehouse or the like is provided in a barcode format. I have. The worker connects the picking cart 1 and the picking cart 20 as shown in FIG.
Further, an article container 44 made of, for example, a cardboard for accommodating the picked articles for each delivery destination is placed on the article placing plate 20 of the picking cart 20. Further, picking data necessary for a host computer or the like (not shown) according to an order slip of an article to be picked, that is, codes (or types, if necessary) of a plurality of kinds of articles to be taken out, the number of articles taken out, The data such as the single item weight and the delivery destination are prepared.

Referring to FIG. 4, the information processing device 42
For example, picking data taken by all pickers for one day from the host computer is wireless, floppy,
It waits for being provided by wire or the like, and when this is provided (Y in step 1), the data is sorted for each terminal 10, that is, for each picker, and transmitted for each terminal 10 (steps 2, 3).

In FIG. 5, the terminal 10 of each picker
Then, upon receiving the data from the information processing device 42,
The received data is recorded in the storage device 43 (steps 1 and 2). Here, the storage device 43 stores the type of the article and the storage position information in the warehouse, that is, for example, the number of the shelf, etc., corresponding to the code for identifying the article. Therefore, the CPU 23 reads out the kind and storage position information of the article corresponding to the identification code of the article to be picked first from the storage device 43, and associates the kind of the article, the expected number of pieces to be taken out, and the storage position information with each other. It is displayed on the display 9 (step 3).

Next, the operator pushes the picking cart and the carts 1 and 20 while watching the storage position information of the article to be taken out displayed on the display 9 and moves to the first article storage location. . When the user arrives at the target place, the number of articles to be taken out is taken out from the shelf, and the bar code reader 11 reads the bar code of one of the articles. When the article identification code is read (Y in step 4), the CPU 23 determines whether or not the read code matches the code of the article specified on the display 9 (step 5).

Here, if the two coincide, the procedure proceeds to the measurement of the number of articles by the weight measuring device 40. If the two do not match, a warning process such as sounding a warning sound with the buzzer 41 is performed (step 13), and the operator determines that there is a difference between the articles and returns all the articles taken out to the shelf. Wait for the operator to judge that the barcode is read for one of the articles to be taken out or to attach a wrong barcode to the correct article and input a confirmation signal (step). 14,1
5). When the barcode is read again (Y in step 14), the process returns to step 5. When the confirmation signal is input (Y in step 15), the read barcode data and the data indicating that the barcode is not attached are stored in the storage device 43 (step 16). Proceed to measurement of the number of articles by 40.

The input of the determination signal may be performed by using an operation key provided on the terminal device 10 or a bar code of a determination code attached to a predetermined position of the picking cart 1 may be read by a bar code reader. It is also possible to read and input in step 11.

In the measurement of the number of articles by the weight measuring device 40, it is first determined whether or not an article has been placed based on a change in the measured weight placed on the placement section 14 (step 6). When it is determined that the article is placed, the measured weight at that time is divided by the single item weight of the picking target article read out from the storage device 43, and whether or not the value is an integer that matches the expected number to be taken out, It is determined whether the number of articles taken out is appropriate (step 8).

Here, if the two match, the actual data storage process in the storage device 43 and the printer 1
3 (steps 9 and 10). If the two do not match, a warning process such as sounding a warning sound with the buzzer 41 is performed (step 17), and the operator determines that the number of articles to be taken out is different and increases or decreases the number of articles on the article mounting portion 14. Or, it is determined that the number of articles stored in the shelf is insufficient, and it is waited to input a confirmation signal (steps 18 and 19). When the number of articles on the article placement unit 14 has been increased or decreased (Y in step 18), the process returns to step 7. When the confirmation signal is input (Y in step 19), the process proceeds to the actual data storage processing in the storage device 43 and the output processing by the printer 13 (steps 9 and 10). In the actual data storage processing after the input of the confirmation signal and the output processing by the printer 13 (steps 9 and 10), the data indicating the missing parts and the number of missing parts are stored and printed.

After the actual data storage processing and the output processing by the printer 13 (steps 9 and 10) are completed, it is determined whether or not the picking has been completed for all the articles to be picked using the data in the storage device 43. (Step 11). If it is determined that the picking has not been completed, the process returns to step S3. When it is determined that the processing has been completed, the recording data of all the pickings up to that time is transmitted to the information processing device 42, and the process waits for data relating to the next picking operation to be transmitted from the information processing device 42 ( Step 1).

Returning to FIG. 4, when the information processing device 42 receives the data relating to the picking operation that has been completed from the terminal device 10 in step 4, whether the data of the next picking operation for the picker of the terminal device 10 remains. It is determined whether or not it is (step 5). If the next data remains, the data of the next picking operation is transmitted to the terminal device 10. If there is no more data left,
In other words, if all the work of the picker of the terminal device 10 has been completed for the day, the data received so far from the terminal device 10 is printed out, for example, organized by customer (step 8), It is determined whether or not the work has been completed for all the terminals 10 (step 9).
If it is determined that the operation has not been completed for all the terminals 10, the process waits for data transmission from the terminals 10 (step 4). Conversely, if it is determined that the work has been completed for all the terminals 10, the data received from all the terminals 10 is transmitted to the host computer by wireless transmission, for example (step 10).

The picker that has completed the series of picking of the range of the data transmitted at one time from the information processing device 42, removes the picking cart 1 and the carts 1 and 20 from each other.
It is moved to a predetermined position in the picking place, where the picking cart 1 and the picking cart 20 are disconnected, and the worker himself or the worker in charge of delivery picks up the cart 2
Only 0 can be moved to the delivery point. The picking cart 1 separated from the trolley 20 is connected to another picking trolley 20 on which articles have not yet been placed, and used for the next series of picking operations.
