[0021]
Although the four filling devices 31 and the labeling devices 33 and the boxing devices 34 have substantially the same processing capacity, the number (four) of the filling devices 31 is the same as that of the labeling devices 33 and the boxing devices 34. Since the number is larger than the number (one), four work moving shelf systems 10 according to the present invention having a buffer function of storing the work W between the filling device 31 and the labeling device 33 are arranged. 1 and 3, only one work moving shelf system 10 is shown for convenience.
[0022]
Since the contents 35 of the work W are made of high-temperature ink, the work moving shelf system 10 also has a function of cooling the ink of the work W during storage of the work W.
[0023]
Next, the work moving shelf system 10 will be described. As shown in FIGS. 1 and 3, the work moving shelf system 10 includes a frame 10a, a supply conveyor 11 and a discharge conveyor 12 fixed to the frame 10a, and a moving shelf 13 movably provided on the frame 10a. Have.
[0024]
At the entrance side of the supply conveyor 11 fixed to the frame 10a, an entrance conveyor 21 for feeding the work W obtained in each filling device 31 to the supply conveyor 11 side is provided. Further, on the exit side of the discharge conveyor 12, an exit conveyor 22 for sending the work W to the labeling device 33 is provided.
[0025]
Next, the supply conveyor 11, the discharge conveyor 12, and the moving shelf 13 will be described in further detail.
[0026]
The supply conveyer 11 has a first base 11a that is elongated in the supply direction of the workpiece W, and a plurality of first combs 11b protruding from the first base 11a to one side, for example, to the right in FIGS. Each of the first comb portions 11b includes a driving roller that is driven to rotate.
[0027]
Further, the discharge conveyor 12 has a second base 12a extending elongated in the discharge direction of the work W (the same direction as the supply direction of the work W), and protrudes from the second base 12a to one side (the right side in FIGS. 1 and 3). And a plurality of second comb portions 12b, each of which is composed of a drive roller that is driven to rotate.
[0028]
Further, the movable shelf 13 has a third base 13a extending in the supply direction (the same direction as the discharge direction) of the work W, and a number of third combs protruding from the third base 13a to the other side (the left side in FIGS. 1 and 3). 13b. The third comb portions 13b are each fixed to the third base portion 13a.
[0029]
The supply conveyor 11 and the discharge conveyor 12 are arranged at substantially the same height, and are spaced apart from each other and arranged in parallel when viewed from a plane. The moving shelf 13 rises in the frame 10 a on the side of the supply conveyor 11, and at this time, the third comb portion 13 b of the moving shelf 13 intersects with the first comb portion 11 b of the supply conveyor 11. The moving shelf 13 moves horizontally in the upper part of the frame 10a toward the discharge conveyor 12 and then descends in the frame 10a. At this time, the third comb portion 13b of the moving shelf 13 is connected to the second comb portion 12b of the discharge conveyor 12. They are crossing. The moving shelf 13 moves horizontally from the discharge conveyor 12 side to the supply conveyor 11 side below the frame 10a.
[0030]
By the way, a guide 15 for guiding the movable conveyor 13 along the above-mentioned movement locus is provided in the frame 10a, and the movable conveyor 13 is driven by the drive chain 16 and moves along the guide 15. I do. Further, the moving shelves 13 are arranged, for example, at 15 levels on the supply conveyor 11 side and at 15 levels, for example, on the discharging conveyor 12 side, for a total of 2 rows × 15 levels. Has become.
[0031]
Next, the operation of the present embodiment having such a configuration will be described.
[0032]
As described above, in the four filling devices 31 in the preceding process, the high temperature ink is filled in the container 35, and the work W is obtained.
[0033]
The work W is sent from the filling device 31 to the supply conveyor 11 of the work moving shelf system 10 via the entrance conveyor 21. Since the first comb portions 11b of the supply conveyor 11 are each composed of a driving roller, the workpieces W are sequentially sent to the exit conveyor 22 side on the first comb portions 11b of the supply conveyor 11.
[0034]
When the work W is full on the supply conveyor 11 in this way, the moving shelf 13 arranged on the supply conveyor 11 side rises from below the supply conveyor 11. At this time, since the first comb portion 11b of the supply conveyor 11 faces one side and the third comb portion 13b of the moving shelf 13 faces the other side, the third comb portion 13b of the moving shelf 13 is The work W on the supply conveyor 11 intersects with the comb section 11b and is transferred to the movable shelf 13 side.
[0035]
Thereafter, the movable shelf 13 rises in the frame 10a, moves in the horizontal direction toward the discharge conveyor 12 above the frame 10a, and then the movable shelf 13 descends in the frame 10a.
[0036]
The movable shelf 13 maintains its posture so that the third comb portion 13b always faces the other side during horizontal movement and descent. Therefore, when the movable shelf 13 passes through the discharge conveyor 12, the third comb portion 13b of the movable shelf 13 faces the other side while the second comb portion 12b of the discharge conveyor 12 faces one side. ing. Accordingly, the third comb portion 13b of the moving shelf 13 intersects with the second comb portion 12b of the discharge conveyor 12, and the work W on the moving shelf 13 is transferred to the discharge conveyor 12 side.
[0037]
The work W on the discharge conveyor 12 is driven by the second comb unit 12b and discharged to the labeling device 33 and the box packing device 34 via the outlet conveyor 22. Next, a label is attached to the work W in the label applying device 33, and the work W is packed in a box in the box packing device.
[0038]
As described above, according to the present embodiment, the supply, storage, and discharge of the work W can be promptly performed by the work moving shelf system 10 having the buffer function. This eliminates the need to manually supply, store, and discharge the work W.
[0039]
Further, in the work moving shelf system 10, since the moving shelf 13 itself is movable, the installation area is reduced as compared with a stacker crane having a shelf and a crane unit for supplying and discharging the work to and from the shelf. be able to.
[0040]
The works W sent from the entrance conveyor 21 are sequentially arranged on the supply conveyor 11 from the exit conveyor 22 to the entrance conveyor 21 in the order in which they are sent. When the work W on the supply conveyor 11 is transferred to the discharge conveyor 12 by the moving shelf 13, the work W is similarly sequentially arranged from the exit conveyor 22 to the entrance conveyor 21 in the order in which they are sent. Will be. Therefore, the work W sent from the inlet conveyor 21 to the supply conveyor 11 can be discharged from the discharge conveyor 11 to the outlet conveyor 22 in the order in which the work W is sent, and the work W is first-in first-out (first-in first-out order). Can be executed reliably.
[0041]
Therefore, each work W filled with the high-temperature ink can be stored in the work moving shelf system 10 for a uniform time, and the ink can be cooled at the same time. In this case, since the cooling time of the ink in the work W can be made uniform, the work W having the ink of uniform quality can be sent to the subsequent process.
[0042]
In the above-described embodiment, an example is shown in which the work moving shelf system is installed between the step of filling the high-temperature ink to obtain the work W and the labeling step and the box packing step of the work W, but is not limited thereto. Alternatively, the work moving shelf system may be installed in the following production line.
(1) Canned production line (2) Beverage production line (3) Small parts production / packing line (4) Can production / sorting / packing line (5) Courier / mail parcel sorting / truck loading line (6) Other production lines in general
【The invention's effect】
As described above, according to the present invention, supply, storage, and discharge of a work can be easily performed, and the installation area of the work moving shelf system can be reduced. Further, it is possible to supply and discharge work on a first-in first-out basis on the work moving shelf.
