Description

  The present invention relates to a so-called digital picking system that picks out various kinds of articles stored in a specified box while following the instructions of a plurality of display lamps and puts them into individual collection boxes to be conveyed.

  In such a system, it is natural that a large variety of articles are accurately put into a predetermined collection box in a short time, and a plurality of people work simultaneously in the zones in their respective areas of responsibility. In some cases, the contents of articles or zones are changed frequently.

  Furthermore, when efficiently storing a large variety of goods, the storage boxes installed on the storage shelves are used in various sizes depending on the product.

  In Patent Document 1, the system is controlled so that a zone display unit with a variable display color can be handled with respect to the background, and the picking display unit in the article storage shelf is mechanically slidably and fixedly attached. The structure is presented.

  Patent Document 2 also presents a structure that facilitates mechanical replacement by using a curl-type cable and a detachable connector that are effective in changing the position and adding a picking display section in Patent Document 1. Yes.

  As shown in these documents, in the current digital picking system, the picking display unit is installed in a part of the storage shelf with a space, and is basically attached and detached mechanically according to the product size and position as necessary. Is moving.

  Furthermore, when the number of workers in the conventional structure increases or decreases, the zone area needs to be changed, and the zone partition is different when the size of the storage box for the item differs depending on the size and quantity of the stored item. The display position to be inclined has an inclination in the vertical direction, and the setting position also differs depending on the content of the target article.

  On the other hand, as shown in Non-Patent Document 1 and Non-Patent Document 2, the human viewing angle is set to about 200 degrees in the horizontal direction and about 125 degrees in the vertical direction, and the stable gaze is quickly and stably seen. The field of view is said to be about 60 to 90 degrees in the horizontal direction and about 45 to 70 degrees in the vertical direction. In other words, since the visual field in the vertical direction is narrower than that in the horizontal direction, it is desirable to avoid changing the horizontal region between the upper and lower sides of the storage shelf as much as possible in the display that is the partition of the zone. If it is confirmed that the vertical direction is the same at the partition boundary of the zone, it is possible to make a clear area determination from an area that can be visually confirmed in the horizontal direction to an area that appears indefinitely on the retina.

“Human Vision and Display”, [online], February 24, 2010, [December 10, 2014 search], Internet (http: div.net/old/violasiderea/804.html) Kiyokawa Kiyoshi, “4.5.3 Wide-angle high-definition display”, Technical trend report, Optoelectronic Industry and Technology Promotion Association, 2001, p. 395-398

  However, in the so-called digital picking system, when handling a large variety of goods, the location of the picking indicator must be moved frequently due to the multiple storage boxes, etc. Handling becomes complicated and a burden is imposed on the cable and the connector, which is not only expensive but also causes a failure during handling. In addition, when setting the picking indicator according to the position of the storage box of the product, the position of the display unit indicating the zone range in the vertical direction is shifted depending on the arrangement of the storage box, and the zone boundary becomes unclear. There was a problem. It is an object to solve such a problem.

  To solve this problem, as shown in claim 1, a plurality of frontage openings are provided in the horizontal direction, and the indicator is provided in a substantially continuous state with respect to the horizontal direction of each row of the storage shelves configured in multiple stages. It is said.

  Further, as shown in claim 2, the display unit recognizes a recognition display unit for picking, a confirmation instruction unit input when the work operation is completed, a quantity display unit indicating the number of picking, and a horizontal work zone. It is comprised by the boundary display part.

  Further, as shown in claim 3, the recognition display unit for picking the display device and the confirmation instruction unit at the completion of the operation include an illumination type switch, and the quantity display unit is as shown in claim 4. Has a digital display function

  The boundary display unit of the display is located at the left and right ends of the display as shown in claim 5 and has a display function capable of changing a display color for each boundary zone. When the storage shelf is always in a state where it can be recognized as a substantially vertical line or a vertical vertical line with respect to the vertical direction of the storage shelf, lighting of the color that can be recognized as the same instruction is turned on or blinking, so that the operator can accurately Zone recognition is possible.

  Further, the boundary display section of the display device may be formed by forming recognition devices for boundary display in a single or a plurality of columns in the vertical direction, as shown in claim 6. That is, it is possible to combine a vertically long shape and a plurality of displays for clarifying the recognition in the vertical direction.

  Here, as shown in claim 6, the display unit is smaller than the width dimension of the target storage box, preferably sufficiently smaller than half the size of the storage box, and the gap between the continuous display and the subsequent display unit is preferable. By arranging them close to zero, the positional accuracy of the vertical row increases, and the operator is accurately recognized.

  Furthermore, the input information of the display or confirmation work on the display unit enables a smooth series of operations by interlocking with the picking information properly arranged in the storage shelf through the control management unit.

  Further, in order to enhance the recognition of the recognition display unit for picking, the boundary display unit juxtaposed in the display unit for picking is displayed in the same color as the picking instruction display unit in addition to increasing the luminance of the display unit. It is also possible to increase the lighting area by lighting with a color different from the color.

  As for the vertical display, movie images and display are basically horizontally long and the aspect ratio is about 1.3 to 1.7. Since there are two eyes on the left and right, it is known that the horizontal field of view is wide as shown in Non-Patent Documents 1 and 2. That is, when discriminating the boundary area at the upper and lower shelf positions of the storage shelves to be picked, if the boundary position is shifted in the vertical direction, the visual field area is pointed in that direction to accurately determine the boundary area. Because it has to be done, it will force extra action than the time that the brain judges, which may lead to erroneous operation. Here, if the boundary area is always in the vertical position at the upper and lower shelf positions of a plurality of stages, the judgment can be made when entering a part of the visual field area, so the operation is greatly simplified, and the time However, it is possible to make judgments without mistakes in a short time.

  According to the picking system according to the present invention, the operator's zone may be changed by being installed at the optimum position of the storage shelf according to information such as the size of the storage box corresponding to various kinds of articles and the picking frequency. Since the zone area is automatically determined and displayed, and the position of the zone boundary is the same in the vertical direction, the storage boxes can be efficiently arranged on the storage shelf. Therefore, the display is easy to see without mistakes for the operator, and accuracy, efficiency, and safety are improved.

In the lamp tracking type picking system, a zone is partitioned in units of racks of storage shelves. This is an example in the case where the storage shelf is not partitioned in units of racks. It is the example which has arrange | positioned the storage box of a different magnitude | size, and is the figure which showed the positional relationship of the position of a storage box and a display.

  Hereinafter, a sorting device according to an embodiment of the present invention will be described with reference to the drawings. In the following, the range necessary for the description for achieving the object of the present invention is schematically shown, and the range necessary for the description of the relevant part of the present invention will be mainly described. According to a known technique.

  FIG. 1 shows that storage boxes 3 of the same size are stored in a storage shelf 1 in three rows and three stages in a rack 2, and five workers 6 perform zone work in units of one rack or a plurality of racks. An example is shown.

  FIG. 2 shows an example of the case where four workers 6 correspond in the state of the storage shelf 1 in FIG. 1 and shows a case where a zone is set in units of storage boxes in the rack 2. The case where the inside storage box is a uniform size is shown.

FIG. 3 is a diagram showing three types of large, medium, and small sizes of the storage box 3 in an example in which three display units 4 are arranged on each of the four storage shelves 1. As described above, there may be a case where it is difficult to discriminate between the two storage boxes 3 at a predetermined display position. In that case, as shown in FIG. 3B, the position of the display is mechanically moved in the direction indicated by the arrow symbol (S), and when necessary, the lamp of the display unit 4 is blinked as shown in FIG. 3C. is there. For convenience, the flashing mark (L) in bold is written on the indicator at the flashing point, and the other flashing points at that time are indicated by the flashing mark in a thin dotted line, but this point does not flash. It has disappeared. Further, when the zones are set in units of storage boxes in the rack, if the storage boxes 3 are not uniform, the zone positions (Z ₁ , Z ₂ ) are inclined with respect to the vertical direction as shown here. It will be.

  FIG. 4 shows the structure of the first display unit in the present plan, the digital display unit 43 for displaying the quantity, the lighting display unit 42 for showing the picking instruction and the work completion input, and lighting the left and right borders. It has the display parts 44 and 45 for showing with a display color.

FIG. 5 shows an example in which three types of large, medium and small storage boxes 3 are arranged on each shelf in which a continuously arranged display is incorporated in the shelf portion of a four-stage storage shelf 1 as shown in FIG. For example, in a state where the storage boxes 3 corresponding to FIGS. 3A to 3D are installed, as shown in FIG. 5B, a display section 42 for inputting a lighting instruction indicating completion of picking and an operation completion is provided at the substantially central portion of each storage box 3. This indicates that the determination of identification with the adjacent storage box becomes clear. Further, when the zone is set for each storage box in the rack, even if the storage box 3 is not uniform, the zone position display (Z ₃ , Z ₄ ) is a picking instruction of the display unit 4 as shown in FIG. 5C. Since the lighting display part 42 and the display parts 44 and 45 indicating the boundary part blink or light on the different display parts 4, they are displayed evenly in the vertical direction without causing an inclination as in the conventional method. It becomes possible to recognize correctly.

  In other words, even if the region where the gazing point of the human eye appears quickly and stably becomes narrower in the vertical direction than in the horizontal direction, instant recognition is facilitated by vertically lining up at the same position in the vertical position. Therefore, accurate and gentle instructions can be given to human eyes.

  FIG. 6 shows an example of zone display in a state corresponding to FIG. 2, in which the lamps of the display portions 44 and 45 indicating the left and right boundary portions in the first display portion 4 shown in FIG. Illuminating with the symbol indicates that, for example, four workers 6 set a zone in units of storage boxes in the rack 2. For example, if the lamp of the left end display unit 45 in the left first display unit 4 in the left end zone (a) lights up red, the lamp of the right end display unit 44 in the same zone (a) also has the same red color. By indicating the lit display, the zone can be recognized, and the lamps of the display units 44 and 45 in the first display unit 4 located on the left and right of the adjacent right zone (b) are different from red, for example, lit in blue Each boundary can be determined by displaying. Incidentally, if the power consumption is not taken into consideration, the same effect can be obtained by lighting all the areas in the same color.

  FIG. 6 shows an example in which storage boxes 3 having a uniform size are arranged. However, when there are many storage boxes 3 of different sizes, a zone is set for each storage box in the rack 2. Even in this case, the same effect can be obtained as shown in FIG. 5C.

  FIG. 7 shows an example of a technique in the conventional method. That is, various target articles are stored in the storage box 3 stored in the storage shelf 2, and the operator picks the target articles of the quantity displayed on the numerical display from the storage box 3 at the position where the picking display is displayed, While moving from the upstream on the belt conveyor 9, the target article is put into the collection box 8 at the position indicated by the guide lamp 7. Further, various instruction lamps and numerical displays are displayed according to information managed by the control unit so that the designated article is accurately picked and put into a regular collection box.

  The present invention is an invention relating to the storage shelf 2, the storage box 3, and the display unit 4 in FIG. 7. A series of operations, that is, the articles instructed to be picked into the collection box 8 which moves on the belt conveyor 9 are guided by the guide lamp 7 The work to be put into the collection box 8 corresponding to the display is the same as the conventional work.

  FIG. 8 shows a visual field region 51 having a horizontal viewing angle (about 200 degrees) and a vertical viewing angle (about 125 degrees, precisely 50 degrees and 75 degrees below), and a gaze point of the eye. Is a view in which a stable gazing area 52 (horizontal direction 60 to 90 degrees, vertical direction 45 to 70 degrees) is superimposed.

  FIG. 9 shows the visual field area 51 and the stable focus visual field area 52 that are visible when the worker 6 located in front of the storage shelf is stationary, in accordance with the ratio of FIG. 8, and by moving the head horizontally. The area is widened, and the positions of the uppermost and lowermost storage boxes need to shake their heads up and down, left and right.

  In the lamp tracking type picking system according to the present invention, the display position of the picking indicator with respect to the storage box is set at the same time as the storage box according to the information such as the size of the storage box and the picking frequency corresponding to various kinds of articles. It is automatically determined and the zone area is displayed automatically when the operator's zone is changed, and the position of the zone boundary is the same in the vertical direction. Since it is possible to perform efficient arrangement and an easy-to-see display without mistakes for workers, the industrial utility value is increased.
