Configured. In the worker space 5 between the storage shelf 3 and the first collection container transport means 6, the worker X is arranged corresponding to each zone, and one worker X corresponds to one In charge of the zone (12 frontage).

  The storage shelf 3 is a fluidized shelf, for example, and has a frame 11, and the frame 11 is provided with a plurality of storage units 2 for storing a plurality of articles W in a storage container B. ing. Each storage unit 2 includes a plurality of free rollers 12 arranged in parallel in a downwardly inclined manner from the rear side to the front side of the frame body 11, and the top of the free rollers 12 placed on the free rollers 12. It has a stopper 13 that abuts the storage container B, and the article W is accommodated above the free rollers 12.

  Then, when the first storage container B becomes empty, the worker X moves the empty storage container B from the free roller 12 onto the transport surface 10a of the storage container transport means 10. When the first storage container B is taken out from the free roller 12, the subsequent storage container B moves forward on the free roller 12 by its own weight until it comes into contact with the stopper 13. The replenishment of the storage container B onto the free roller 12, that is, the replenishment of the article W to the storage unit 2, is performed from the rear side of the storage shelf 3.

  For example, the type of the article W is different for each storage unit 2. That is, a plurality of identical articles W are stored in one storage unit 2. Of course, when there is an article W with a high order frequency, the same kind of article W may be stored in the plurality of storage units 2.

  Further, on the front side of the storage shelf 3, a storage unit instruction means 15 is provided corresponding to each storage unit 2 and instructing the storage unit 2 where the article W to be picked is stored for the worker X. Is provided. That is, the storage unit instruction means 15 is provided for each storage unit 2. Each storage unit instruction means 15 is instructed by light from a light source, and is constituted by, for example, an LED lamp as a display.

  The first collection container transport means 6, which is a first collection line arranged horizontally on the storage shelf 3 side, is a roller conveyor, for example, and has a conveyor frame 22. A conveyance roller 23 is rotatably provided.

  The plurality of transport rollers 23 are synchronously driven and rotated all at once by the power from a single drive source 24 such as a motor, and transport the plurality of collection containers A in the transport direction. A plurality of transport rollers 23 constitute a horizontal transport surface 6a.

  Further, on the surface of the conveyor frame 22 facing the storage shelf 3, each collection container A on the conveyance surface 6 a of the first collection container conveyance means 6, that is, the first collection container conveyance means 6 is stopped. Occasionally located corresponding to each collection container A on the stopped first collection container transport means 6, the worker X is instructed to the collection container A to which the article W picked from the storage unit 2 should be put. There is provided first collection container instruction means 26 which is a container instruction means to perform. That is, the first collection container instructing means 26 is provided for each collection container A stopped on the transport surface 6a. Each first collection container instructing means 26 is instructed by light from a light source, and is composed of, for example, an LED lamp as a display.

  Similar to the first collection container transport means 6, the second collection container transport means 7, which is a second collection line disposed in an inclined manner on the storage container transport means 10 side, is a roller conveyor, for example, a conveyor frame 32. The conveyor frame 32 is provided with a plurality of conveyance rollers 33 rotatably.

  The plurality of transport rollers 33 are synchronously driven and rotated all at once by power from a single drive source 34 such as a motor, and transport the plurality of collection containers A in the transport direction. A plurality of transport rollers 33 constitute an inclined transport surface 7a.

  Further, as shown in FIG. 1, the single drive source 24 of the first collection container transport means 6 and the single drive source 34 of the second collection container transport means 7 are electrically connected to the control means 36. The control means 36 controls both the conveying means 6 and 7 individually. That is, the drive and stop of the first collection container transport means 6 and the drive and stop of the second collection container transport means 7 are individually controlled.

  The storage container transport means 10 is a roller conveyor, for example, as with both transport means 6 and 7, and has a conveyor frame 42. A plurality of transport rollers 43 are rotatably provided on the conveyor frame 42. The plurality of transport rollers 43 are driven and rotated by power from a motor (not shown) to transport the empty storage container B. A plurality of transport rollers 43 form a horizontal transport surface 10a.

  Further, on the surface of the conveyor frame 42 facing the storage shelf 3, each collection container A on the transport surface 7 a of the second collection container transport means 7, that is, the second collection container transport means 7 is stopped. Occasionally located corresponding to each collection container A on the stopped second collection container transport means 7, the worker X is instructed to the collection container A to which the article W picked from the storage unit 2 should be put. The second collection container instruction means 46 is provided as the container instruction means. That is, the second collection container instructing means 46 is provided for each collection container A stopped on the transport surface 7a. Each second collection container instructing means 46 is instructed by light from a light source, and is constituted by, for example, an LED lamp that is a display.

  On the other hand, as shown in FIG. 1 and FIG. 2, the picking system 1 picks up the number of articles W to be picked from one storage unit 2 according to an instruction from the storage unit instruction means 15 for the worker X (picking Pick number instruction means 51 for instructing (quantity) is provided.

  The pick number instruction means 51 is provided for each zone of the storage shelf 3, and one pick number instruction means 51 for one worker X is disposed at a position where it can be viewed from the worker X. Each pick number instruction means 51 is constituted by a liquid crystal display device, for example, and has a display screen 52 for displaying the number of picks (for example, an integer of 1 to 5).

  For example, when “3” is displayed on the display screen 52 of the pick number instruction means 51, the worker X is the same from the one storage unit 2 related to the instruction (storage unit instruction) by the storage unit instruction means 15. The three articles W are picked at the same time, and the articles W held in this hand are used as instructions (container instructions) by the container instruction means 26, 46 (the first collection container instruction means 26 or the second collection container instruction means 46). Three of them are put into the same collection container A. That is, for example, out of five collection containers A located on the first collection container transport means 6 or the second collection container transport means 7, three articles W are in one designated collection container A. It is thrown in and stored simultaneously.

  As described above, when there are a plurality of picks related to the instruction (pick number instruction) by the pick number instruction means 51, that is, n-point collection work (n is an integer of 2 to 5, for example, picking work of n articles W) Storage section instruction means 15 and container instruction means 26, 46, for example, blinks green, and a warning sound is sent to inform worker X that it is an n-point collection work. A generating means (not shown) emits.

  In the case where the number of picks related to the instruction by the pick number instruction means 51 is singular, that is, in the case of one-point collection work (picking work and loading work of one article W), the storage unit instruction means 15 and the container instruction The means 26 and 46 are lit in green, for example.

  Further, as shown in FIG. 2, the picking system 1 has an article W having a plurality of pick numbers according to an instruction from the pick number instructing means 51 when the worker X performs a multi-point collection work that is an n-point collection work. Is provided with a switch means 53 for confirming the work after being put into the collection container A.

  The switch means 53 is provided for each zone of the storage shelf 3 in the same manner as the pick number instruction means 51, and one switch means 53 is arranged at a position where the worker X can operate for one worker X. Has been.

  Each switch means 53 is composed of, for example, a rope switch, and is biased in the pulling direction by an urging body such as a spring and is brought into a substantially horizontal state and can be operated by the operator X. And a switch that is turned on when the rope 54 is pulled and turned off when the pulling operation is released. For example, although not shown, the switch means 53 may be a tape switch or the like provided on the conveyor frame 22 of the first collection container transport means 6.

  When the switch means 53 is turned on by the worker X during the n-point collection work, the storage unit instruction unit 15 and the container instruction units 26 and 46 are turned off, and one pick instruction (storage unit instruction, container A sound generation means (not shown) emits a completion sound for notifying the worker X that the collection work related to the collection instruction including the instruction and the pick number instruction is completed. Thereafter, the next pick instruction is given to the worker X under the control of the control means 36. Further, the control means 36 drives the conveying means 6 and 7 on the completed side when the collection work related to the collection container (knitting container group) A of five knitting (plural knitting) is completed in all zones. The collection container A is then carried out.

  Further, as shown in FIGS. 1 and 3, the picking system 1 includes a photoelectric sensor or the like that detects whether or not an article W has been put into one collection container A according to instructions from the container instruction means 26 and 46. Detection means (input sensor), that is, for example, first detection means 61 and second detection means 62 are provided.

  The first detection means 61 detects whether or not the article W has been put into the collection container A according to the instruction from the first collection container instruction means 26, and is provided for each first collection container instruction means 26. And corresponding to each collection container A on the first collection container transport means 6. Each first detection unit 61 includes a light projecting unit 61a that projects detection light and a light receiving unit 61b that receives the detection light from the light projecting unit 61a.

  The second detection means 62 detects whether or not the article W has been put into the collection container A according to the instruction from the second collection container instruction means 46, and is provided for each second collection container instruction means 46. And corresponding to each collection container A on the second collection container transport means 7. Each of the second detection means 62 includes a light projecting unit 62a that projects detection light and a light receiving unit 62b that receives the detection light from the light projecting unit 62a.

  When the detection light on the one collection container A related to the instruction by the container instruction means 26 and 46 is blocked by the hand of the article W or the operator X during the one-point collection work, the storage unit instruction means 15 and the container Completion to inform the worker X that the instruction means 26 and 46 are extinguished and the collection work related to one pick instruction (collection instruction comprising storage section instruction, container instruction and pick number instruction) is completed. Sound generating means (not shown) emits sound. Thereafter, the next pick instruction is given to the worker X under the control of the control means 36. Further, the control means 36 drives the conveying means 6 and 7 on the completed side when the collection work related to the collection container (knitting container group) A of five knitting (plural knitting) is completed in all zones. The collection container A is then carried out.

  Here, the control means 36 is composed of hardware such as a CPU and memory and software such as a program. The instruction means 15, 26, 46, 51 instructs the operator X to pick, that is, a storage unit instruction, Collecting instructions including container instructions and pick number instructions are determined for each group of organized containers, and the instruction means 15, 26, 46, 51 are appropriately controlled so that the determined instructions are issued to the worker X. .

  Then, the control means 36 rearranges the pick instructions so that the pick instructions of the same number of picks do not continue (rearrangement function) and the function of dividing the pick instructions based on a preset division table (split number division) Function) and a function of dividing the pick instruction based on the item information (item information dividing function).

  First, the rearrangement by the control means 36 will be described. When the pick instructions of the same number of picks continue in one knitting container group, the control means 36 has different pick numbers in the one knitting container group. When there is a pick instruction, another pick instruction is inserted between pick instructions having the same number of picks.

  For example, as shown in FIG. 5, when the number of picks in the three pick instructions is “2-2-1”, the control unit 36 sets the number of picks to “2-1-2”. Rearrange pick instructions.

  For this reason, pick instructions of the same number of picks do not continue, the same number of collection work by the worker X does not continue, and it is difficult for the worker X to mistake the number of articles that is the number of picks of the article W to be picked, Collecting work mistakes by the worker X are reduced.

  Next, the pick number division by the control means 36 will be described. In the control means 36, the number of picks in one pick instruction (one pick instruction) is equal to or greater than a preset division setting value (for example, “5” or the like). In this case, the one pick instruction is divided into a plurality of pick instructions (a plurality of pick instructions) whose number of picks is less than the preset division setting value based on a preset division table. Note that a pick instruction having a number of picks less than the division setting value is instructed without being divided.

  FIG. 6 shows an example of a division table whose division setting value is “5”, and FIG. 7 shows an example of a division table whose division setting value is “6”. The division set value is the number of articles W that can be held by the worker X at a time and can be visually confirmed, and is any one of “4”, “5”, and “6”, for example. It is one.

  Further, the control means 36 does not continue pick instructions having the same number of picks when dividing one pick instruction whose number of picks is equal to or greater than the division setting value based on the division table. For example, the number of picks “8” is divided into “2-4-2” and “5-3” instead of “4-4” and “2-2-2-2”, for example.

  Furthermore, the control means 36 does not create a pick instruction with the number of picks of “1” when dividing one pick instruction whose number of picks is equal to or greater than the division setting value based on the division table. In order to improve work efficiency, it is preferable not to create a pick instruction with the number of picks “1”, but a pick instruction with the number of picks “1” may be generated.

  Further, regarding the number of picks divided, it is preferable to set the number of instructions to be smaller, and it is preferable that the number of picks after the division is not extremely open or biased. For example, the number of picks “9” is divided into “5-4” and “3-4-2” instead of “8-1”.

  Since the pick number dividing function divides the pick instruction having the pick number equal to or greater than the set division value into a plurality of parts, the worker X can check the picked articles W at the same time with each pick instruction. As a result, it becomes difficult for the worker X to mistake the number of articles, which is the number of picks of the article W to be picked, and mistakes in collecting work by the worker X are reduced.

  Next, the item information division by the control means 36 will be described. The control means 36 gives a plurality of pick instructions for a specific article W based on item information (article information) including, for example, the size, weight, and characteristics of the article W. Divide into pick instructions.

  That is, the control means 36 calculates the number of items that can be collected in one operation by the worker X based on the item information, and uses the calculated number as an instruction upper limit value, and one pick instruction is less than the instruction upper limit value. Divide into multiple pick instructions.

  For example, in relation to the size / weight, the number of items that can be held by the worker X at one time by hand is 2 (the instruction upper limit value for item information division is “2”). When the number of picks is “8”, for example, it is divided into five pick instructions “2-1-2-1-2”. At this time, pick instructions having the same number of picks are not consecutively performed. For example, when the article W is easy to deform and difficult to hold, the instruction upper limit value can be set to “1”, for example.

  And since the pick instruction in which the number of picks exceeds the instruction upper limit value is divided into a plurality of pieces by the item information dividing function in this way, excessive holding of the article by the worker X is avoided, and dropping or breakage of the article W is reduced. .

  Here, there are eight patterns of combinations of the three functions as shown in FIG. For example, “Pattern No. 4” is a case where all of the pick number division, item information division, and rearrangement are performed.

  FIG. 9 shows an example in which the pick instruction for one knitted container group in a certain zone is three times. FIG. 10 shows an example in which the pick instruction for one knitted container group in a certain zone is performed twice. The pattern numbers in FIGS. 9 and 10 correspond to the pattern numbers in FIG.

  The pick number division in FIG. 9 is based on the division table shown in FIG. 6, but the pick number division in FIG. 10 is different from the division table shown in FIG. 1 ”).

  FIG. 11 shows an example in which pick instructions with the same number of picks are given even if rearrangement is performed. That is, as shown in the example shown in FIG. 11, even when rearrangement is performed for the set number of times, pick instructions with the same number of picks may continue.

  In such a case, the control means 36 rearranges the pick instructions so that pick instructions of the same number of picks regarding the same storage unit (frontage) 2 do not continue. In other words, the control means 36, when pick instructions of the same frontage and the same number of picks continue, when there are other pick instructions having the same number of picks but different frontage, the other pick instructions are the same frontage and Interrupt between pick instructions with the same number of picks. As a result, the same number of collection work for the same article W by the worker X does not continue, and the collection work mistake by the worker X is reduced.

  Next, the process of the control means 36 is demonstrated with reference to the flowchart shown in FIG.

  When each knitted container group including a plurality of collection containers A starts (or arrives) (step 1), the control means 36 searches the data to determine whether there is a pick instruction (step 2).

  If it is determined in step 2 that there is a pick instruction, a pick instruction dividing process is started (step 3), and it is determined whether or not the number of picks in the pick instruction is equal to or greater than a set division value (step 4).

  If it is determined in step 4 that the number of picks in the pick instruction is equal to or greater than the set division value, the pick instruction is divided based on the division table (step 5).

  Next, the control means 36 refers to the item information (step 6), and determines whether or not division by the item information is necessary (step 7).

  If it is determined in step 7 that division by item information is necessary, whether the number of picks in the pick instruction exceeds the instruction upper limit value (upper limit value at the time of division set only for a specific article according to article characteristics) It is determined whether or not (step 8).

  If it is determined in step 8 that the number of picks in the pick instruction exceeds the instruction upper limit value, division based on item information is performed, and the pick instruction is divided (step 9).

  On the other hand, if it is determined in step 8 that the number of picks in the pick instruction does not exceed the instruction upper limit value, division by item information is not performed (step 10).

  If it is determined in step 7 that division by item information is not necessary, it is determined whether or not there is a pick instruction for which division processing has not been performed (step 11). Return to step 4.

  If it is determined in step 11 that there are no pick instructions that have not been divided, pick instruction sorting processing for eliminating the same number of picks is started (step 12), and whether or not pick instructions of the same number of picks are consecutive. (Step 13).

  If it is determined in step 13 that the same number of pick instructions are consecutive, it is determined whether there is another pick instruction with a different number of picks (step 14).

  If it is determined in step 14 that there is another pick instruction having a different number of picks, another pick instruction having a different number of picks is interrupted between pick instructions having the same number of picks (step 15).

  On the other hand, if it is determined in step 13 that pick instructions with the same number of picks are not consecutive, or if it is determined in step 14 that there is no other pick instruction with a different number of picks, pick instructions that have not been sorted. If there is a pick instruction that has not been sorted, the process returns to step 13.

  If it is determined in step 16 that there is no pick instruction that has not been sorted, all pick instructions for each knitting container group are determined (step 17).

  According to the picking system 1, the control means 36 has a function of rearranging the pick instructions so that the pick instructions of the same number of picks do not continue, so that the same number of collection work by the worker X does not continue. Therefore, it becomes difficult for the operator X to mistake the number of picks of the article W to be picked, and it is possible to reduce work mistakes by the worker X.

In addition, since the control means 36 has a function of dividing the pick instruction based on the division table,
The operator X does not collect a plurality of times in response to one pick instruction, and therefore, it becomes difficult for the operator X to mistake the number of picks of the article W to be picked. Mitigation can be achieved.

  Furthermore, since the control means 36 has a function of dividing the pick instruction based on the item information that is the product information, it is possible to avoid excessive holding of the article by the worker X and reduce the fall or breakage of the article W.

  In the above embodiment, the configuration including the two rows of transport means 6 and 7 for transporting the collection container A has been described. However, for example, one or three or more rows may be used, and the number of lines of the transport means is arbitrary. is there.

  Further, the number of storage units (frontage) 2 for each zone is not limited to a total of 12 in 4 rows and 3 stages, and may be, for example, 4 rows by 4 stages or 5 rows by 3 stages.

  Furthermore, for example, a configuration in which a loading completion button or the like is provided instead of the detection means 61 and 62 may be used.

  Further, the control means 36 is not limited to one having the three functions of the rearrangement function, the pick number division function, and the item information division function, and may have at least one of these three functions. .

  Furthermore, the division setting value in the pick number division function may be set to “7” or more if the article W that is a collection target is small, for example.

  The pick number instruction means 51 is not limited to the configuration provided for each zone of the storage shelf 3. For example, the pick number instruction means may be provided for each storage unit.

  Further, for example, when a pick number instruction means is provided for each storage unit, the pick number instruction means and the storage unit instruction means may be integrated. That is, for example, the display device that constitutes both the instruction means simultaneously instructs the storage unit and the number of picks, or the display device that constitutes both instruction means instructs the number of picks that also serves as the instruction of the storage unit. A configuration or the like may be used.
