The present invention relates to a gravity type fluidized shelving device which is used by a simple turning operation which is also slid down by gravity and sent back.

[0002]

[Prior art]

 Conventionally, gravity-type fluidized shelving devices having the above-described configurations and uses are described in, for example, Japanese Utility Model Publication No. 58-16987 or Japanese Utility Model Publication No. 1-75004, and belong to publicly known and practical applications. Have been served. The fluidized shelf device described in Japanese Utility Model Publication No. 58-16987 is characterized by a device for changing the direction of an object to be conveyed in a portion where upper and lower fluidized shelves are continuous in a V shape. Immediately, a pedestal equivalent to the upper and lower fluidized shelves divided into a dogleg-shaped continuous portion from the position of the intersection to a length range in which at least one transported object can be placed is called the upper and lower fluidized shelves. It is installed so as to be tiltable so that it can be connected, and the driving means for tilting the pedestal in the vertical direction, the gate for restricting the sliding of the next-order transported object at the end of the upper flow shelf, and the pedestal. The sensor means is provided so as to detect the entry of the transported object. By tilting the pedestal in the vertical direction by the driving means and connecting the pedestal with the upper and lower fluidized shelves alternately, the transported object is transferred from the end of the upper fluidized shelves to the beginning of the lower fluidized shelves.

Further, the fluidized shelving device described in Japanese Utility Model Laid-Open No. 1-75004 described above receives components at the end position of the fluidized shelves for receiving a transport container, which is an object to be transported, and storing the components in the transport container. It is characterized by a turning frame that is convenient for taking out the product for use or processing, or transferring the transport container to the lower fluidized shelf. That is, at the end position of the fluidized shelf, a revolving frame that receives and receives a container for transportation etc. that has slid down on the fluidized shelf is installed by itself at a predetermined angle in a certain direction by the rotation support mechanism with respect to the shelf frame. Has been done. The rolling frame has a substantially L-shape that is connected so as to face the ends of the upper and lower fluidized shelves, and has an L-shaped configuration due to the rotation support mechanism that is oriented substantially at right angles to the sliding direction of the fluidized shelves. The lower corner is rotatably supported. The turning frame has a manual operation lever on the top, can be tilted in a direction to connect with the upper and lower fluidized shelves, and is equipped with a positioning mechanism for temporarily fixing each tilted position of the turning frame.

[0004]

[Problems to be solved by the present invention]

 The pedestal of the gravity type fluidized shelving device described in Japanese Utility Model Publication No. 58-16987 described above uses a small article such as a microcomputer part housed in a received object to be conveyed (conveying container or the like), for example, home electric appliances. It is said that the assembler of the assembly line is not configured to support it by inclining it at an angle suitable for taking it out and using it, and it is difficult for the assembler who spares time to spare.

Next, the fluidized shelving device described in Japanese Utility Model Laid-Open No. 1-75004, and in particular, the turning frame described in FIGS. 6A and 6B of the same publication, stands along an assembly line for household appliances. Although the assembler has a structure to support the transported object by tilting it in front of the stand, it is easy for the assembler to take out small parts, but when sending back an empty transport container, the empty container is removed from the turning frame once. It would be troublesome and time consuming, because it would have to be transferred to the current shelf. Moreover, the manual operation of the turning frame located on the opposite side of the assembly line cannot be performed in an appropriate work posture. In addition, the turning frame described in FIGS. 1A and 1B of the same publication also supports the transported object by inclining it in the front direction of the assembler, so that small articles can be easily taken out. The manually operated lever horizontally blocks the open surface of the conveyed items, which is a hindrance to the troublesome picking work.

Further, the above-described conventional pedestal and turning frame are subject to the condition of sliding down due to gravity when an empty transport container (transported object) is tilted forward and delivered to the lower fluid shelf. Immediately after that, the transported object is inadvertently slipped out of the cradle or turning frame. For this reason, there are many cases in which the transported object that has slipped out carelessly collides with the end part of the upper flow shelf and other shelf frames, which not only prevents smooth delivery but also damages the transported object or the shelf structure. Yes, it has become a problem to be solved.

[0007]

[Means for Solving the Problems]

 As a means for solving the above-mentioned problems of the prior art, a gravity type fluidized shelving device according to the present invention is configured such that a plurality of fluidized shelves 9 and 10 are moved up and down at a gradient at which a transported object 30 slides due to its gravity action. In a gravity type fluidized shelving device installed in a continuous V shape, at least one transported object can be placed from the position of the intersection point 4 of the doglegged portions of the fluidized shelves 9 and 10. One movable shelf 7 equal to the one divided into the range is installed so as to be tiltable in the vertical direction about the intersection 4, and a drive means 17 for tilting the movable shelf 7 is provided. The object 30 to be transported is sized so that it can be placed in the frame of the movable shelf 7 and can be tilted independently of the movable shelf. The inner frame 8 provided with the vertical direction with the intersection 4 as the center It is characterized in that it can be freely tilted and the driving means 15 for tilting the inner frame is installed.

According to the present invention, a plurality of fluidized shelves 9 and 10 are installed in a vertical V-shaped continuous manner with a gradient that the transported object 30 slides due to its gravity action. One movable shelf 7 equivalent to a shape part divided from the position of the intersection 4 to a length range in which at least one transported object 30 can be placed can be tilted in the vertical direction about the intersection 4. Installed on the movable shelf 7 and provided with a sensor means 13 for detecting the arrival of an object to be conveyed on the movable shelf 7 and a driving means 17 for tilting the movable shelf 7, in the frame of the movable shelf 7. The inner frame 8 has a size such that the transferred object 30 can be placed thereon, can be tilted independently of the movable shelf 7, and has a dead end 8a of the transferred object at its tip end. Can be freely tilted up and down around the intersection 4 The driving means 15 for tilting the inner frame 8 is installed, and the first stopper 19 which can freely move in and out is installed at the end portion of the upper flow shelf 9 for feeding the transported object 30 to the movable shelf 7. A second stopper 22 is installed at a position separated from the position of the first stopper by a distance corresponding to the length of the transported object, and the sensor means 13 of the movable shelf 7 detects the arrival of the transported object 30. By controlling the drive parts of the first and second stoppers, the transported object is placed at a position separated from the starting end of the lower flow shelf 10 for delivering the transported object 30 from the movable shelf 7 by a distance corresponding to the length of the transported object. It is also characterized in that a sensor means 24 for detecting the stay is provided.

[0009]

[Action]

 The transported object 30 loaded on the upper fluid shelf 9 slides down the fluid shelf 9 by the action of gravity, is stopped by the first stopper 19 at the end, and the sensor means 14 detects that the object 30 has reached the position. It On the basis of the detection signal, the second stopper 22 on the upstream side is projected, and the sliding down of the next conveyed object 30 is restricted. Alternately, the first stopper 19 is released, and the transported object of the preceding order is advanced to the movable rack 7 of the turning mechanism 6 and stopped at the stop 8a of the inner frame 8.

The arrival of the transported object 30 at the movable shelf 7 is detected by the sensor means 13. Based on the detection signal, the first stopper 19 is ejected, the second stopper 22 is alternately released, and one transported object 30 advances to the first stopper 19. In addition, the driving means 15 of the inner frame 8 tilts the transported object 30 on the movable shelf 7 together with the inner frame forward and downward in the sliding direction up to an angle (position in FIG. 2) suitable for taking out the stored items around the intersection 4. Tilt to. Therefore, the transported object 30 is tilted so as to face the front of the assembler standing along the assembly line of the home electric appliance as shown in FIG. 5, and the assembler does not move its position and turns to the rear. Since the contained items can be taken out without any action, the labor of the assembler at the time of taking out the contained items is reduced and the loss time is also reduced.

Based on a signal (electrical signal) that the assembler has completely taken out the contained items, the drive means 17, 15 for the movable shelf 7 and the inner frame 8 are arranged so that the movable shelf 7 precedes the lower stage flow. It is tilted to a position (position in FIG. 2) where it is connected to the shelf 10. Therefore, the empty transported object 30 placed on the inner frame 8 does not slip accidentally on the inner frame 8 inclined forward and downward due to the sliding resistance with the inner frame 8. Then, at the time when the object 30 to be conveyed is caught from the inner frame 8 to the movable shelf 7 by catching up with the movable shelf 7 that has been tilted to the position where it is connected to the lower flow shelf 10 in advance, the object 30 to be conveyed is transferred. Slides on the movable bear 7 on the coroconveyor 7a due to gravity. In this way, the timing and the angle at which the transported object 30 slides down from the movable shelf 7 to the lower shelves 10 are quantitative.

However, even if a signal indicating that the removal of the contained items is completed is input, the sensor means 24 of the lower flow shelf 10 generates an off signal indicating that the transported object does not stay on the flow shelf 10. Unless this is done, the downward tilting of the inner frame 8 by the drive means 15 is awaited. This is to prevent the subsequent confusion of the automatic control system. Thus, the emptied transported object 30 exits the movable shelf 7 and slides down to the lower fluidized shelf 10, the sensor means 24 detects the arrival (or passage) of the transported object 30, and When the sensor means 13 of the movable shelf 7 detects that there is no object to be conveyed and generates an OFF signal, the driving means 17 causes the movable shelf 7 to tilt to a position (position in FIG. 2) where it is connected to the upper fluid shelf 9. To be done.

In short, the movable shelf 7 of the turning mechanism 6 is tilted stepwise to the position shown in FIG. 2 and the inner frame 8 is tilted stepwise to the position shown in FIG. The posture of taking out the object and the discharge of the emptied object are carried out.

【Example】

 Next, the illustrated embodiment of the present invention will be described. First, FIG. 1 generally shows an embodiment of a gravity type fluidized shelf device. The gravity-type fluidized shelving apparatus 1 has two shelves 9 and 10 above and below a shelf frame 3, each of which is installed in a dogleg shape with a downward slope in which a transported object 30 slides by gravity. Has been done. The fluidized shelves 9 and 10 are configured as roller conveyors. By the way, the upper shelves 9, which are filled with contents and supplied with heavy transported objects 30, are installed at a gentle downward slope of 3 to 4 °, and the empty transported shelves 30 are discharged to the lower level. The fluidized shelves 10 are installed at a slightly steep downward slope of 10 to 15 °. The shelf frame 3 has a rigid frame structure in which resin-coated steel pipes having an outer diameter of φ28 to 32 are adhered to each other by coating and adhering a synthetic resin in a thin and uniform layer on the outer periphery of the thin-walled steel pipe by a joint made of synthetic resin. Are organized as. Casters 33 are attached to the lower surface of the shelf frame 3 so as to be movable. 1 and 3, the shelf frame is constructed as a combination of two independent front and rear frame bodies, both of which are formed by connecting the adjacent columns 3a and 3b with a fastening metal 25 as shown in FIG. It is used on the other hand, but on the other hand, when moving to the installation place, it shows a structure that separates the two frames to facilitate the work, but this is not limited to this, but as one frame or more It can also be implemented in a separable configuration.

Portions of the above-described upper and lower two-stage fluidized shelves 9 and 10 which are continuous with the dogleg shape are provided as a rolling mechanism 6 on the overhanging frame 2 installed so as to project to the left side surface of the shelf frame 3. There is. However, this is a configuration in consideration of the workability of taking out the contained object of the transported object 30 in the product assembly line, and in some cases, it may be implemented with a configuration in which a turning mechanism is provided in the frame of the shelf frame 3. .

The turning mechanism 6 has a length at which at least one transported object 30 can be placed from the position of the intersection 4 with respect to the portions of the upper and lower two-stage fluidized shelves 9 and 10 that are continuous with the dogleg shape. It is composed of a combination of a movable shelf 7 and an inner frame 8 which are divided into a range. The movable shelf 7 is composed of a roller conveyor 7a that can be connected in series with the upper and lower fluidized shelves 9 and 10. The movable shelves 7 are the tips of the overhanging frame 2 and are connected to the upper and lower fluidized shelves 9 and 10. It is installed so that it can be tilted in the vertical direction about the spindle 4 installed at the intersection of the letters. As shown in FIGS. 3 and 4, the specific structure is such that the base ends of the roller conveyor 7a and the vertical frame 7b that constitute the movable shelf 7 are rotatably mounted around the support shaft 4 by a rotary joint 7c. ing. An output rod 17a of a pneumatic cylinder 17 as a driving means for tilting the movable shelf 7 is connected to a substantially central position of the horizontal frame 7d on the free end side. A base end portion of the pneumatic cylinder 17 is rotatably supported by a fixed bracket 18 by a pin 18a. Therefore, when the pneumatic cylinder 17 is extended, the movable rack 7 can be connected to the end of the upper fluid rack 9 at a series of angles as shown in the position of FIG. On the contrary, when the contraction operation is performed, it is possible to connect to the starting end of the lower flow shelf 10 at a series of angles as shown as the position in FIG. It is detected that the transported object 30 has fully loaded (reached) on the movable shelf 7 at a position close to the support shaft 4 on the inner surface of one of the movable conveyors 7a of the movable shelf 7. A detector 13 such as a limit switch is installed as a sensor means.

On the other hand, the movable shelf 7 is housed in a frame surrounded by the roller conveyors 7a, 7a on both sides and the lateral frame 7d on the free end side, and is tiltable independently of the movable shelf 7. Moreover, the inner frame 8 of a size capable of stably mounting the transported object 30 independently is installed in the frame of the movable shelf 7 so as to be tiltable in the vertical direction about the support shaft 4 as well. Has been done. As shown in FIGS. 3 and 4, the specific structure is such that the base end portion of the inner frame 8 is rotatably attached to the support shaft 4 by a rotary joint 8b. At the base end of the inner frame 8, a stop 8a of the transported object 30 is erected vertically upward using the rotary joint 8b. An output rod 15a of a pneumatic cylinder 15 is connected to a central portion near the free end of the inner frame 8 as a driving means for tilting the inner frame 8. The pneumatic cylinder 15 is rotatably supported at its relatively upper position by a trunnion shaft 16a on a fixed bracket 16. Therefore, when the pneumatic cylinder 15 is extended, the inner frame 8 operates independently of the movable shelf 7, and the inner frame 8 moves from the position shown in FIG. In the state of tilting to the upper right as indicated by, the tilt angle is tilted to about 40 to 45 °. Therefore, the inner frame 8 rides on the movable shelf 7 at the position shown in FIG. 2 and lifts the transported object 30 stopped at the front end and stopped at 8a and tilts to the state of the inclination angle. Therefore, as illustrated in FIG. 5, for the worker who takes out and uses the stored items such as the assembled parts accommodated in the transported object 30, the transported object 30 is stored in the front facing direction and is stored. It is supported by inclining it at the most suitable angle for taking out items. Therefore, the worker hardly needs to move, and does not have to take a position to look into the transported object 30, and the contents can be quickly and reliably taken out easily. On the contrary, when the pneumatic cylinder 15 is contracted, the pneumatic cylinder 15 can be tilted rightward from the position shown in FIG. 2 to a position where it is connected to the lower flow shelf 10 at a series of angles. . As a result, the transported object 30 placed on the inner frame 8 is delivered to the roller conveyer 7a of the movable shelf 7 waiting at the preceding position, and flows on the movable shelf 7 in the lower stage. Gravity descends to the shelf 10.

The movable shelves 7 and the inner frame 8 of the turning mechanism 6 described above can be assembled by using the resin-coated metal pipes described above as the respective frame members and connecting them by a joint made of synthetic resin. Next, as shown in FIG. 2, a first stopper 19 that is vertically moved in and out by a pneumatic cylinder 21 is installed at the terminal end of the upper flow shelf 9, and the first stopper 19 moves the material to be transported. The objects 30 are controlled to enter the movable shelf 7 intermittently one by one. Then, a detector 14 such as a limit switch as a sensor means for detecting the transported object 30 stopped by the first stopper 19 by sliding down on the fluidized shelf 9 by the action of gravity is positioned near the end of the fluidized shelf 9. It is installed in. Reference numeral 20 in FIG. 2 is a lever for interlocking the output rod of the pneumatic cylinder 21 and the first stopper 19, and 20a is a fulcrum supporting the intermediate portion. In the same upper flow shelf 9, the pneumatic cylinder 23 vertically moves the upstream side of the position of the first stopper 19 at a position separated by a distance corresponding to the length of one transported object 30. A second stopper 22 that is moved in and out is installed. The second stopper 22 presses the next transported object on the upstream side before releasing the transported object 30 stopped by the first stopper 19 and sliding down the movable shelf 7 by gravity. It is something to put. By the way, when the detector 14 of the upper flow shelf 9 detects the arrival of the transported object 30, the second stopper 22 is pushed out based on the detection signal, and the upstream next-side transported object 30 slides down. Regulate and hold down. In turn, the first stopper 19 is released, and one transported object 30 slides down into the movable shelf 7. When the transported object 30 is completely loaded on the movable shelf 7 and detected by the detector 13, the first stopper 19 is projected based on the detection signal, and then the second stopper 22 is released. Then, the next transported object 30 slides down and is stopped by the first stopper 19. Subsequently, based on the detection signal of the detector 13, the pneumatic cylinder 15 is extended, and the inner frame 8 is tilted to the position shown in FIG. 2 with the transported object 30 placed thereon. At the position of, when the worker takes out the assembled parts and the like housed in the transported object 30 and runs out, the two pneumatic cylinders 15 and 17 are activated based on the operator's signal from the completion button 12 (Fig. 3). The contraction operation is performed, and the movable rack 7 precedes and the inner frame 8 follows, so that both are tilted to the position shown in FIG. When the inner frame 8 catches up with the movable shelf 7 waiting at the preceding position, the empty transported object 30 slides down on the roller conveyor 7a of the movable shelf 7 to the lower flow shelf 10 by the action of gravity. Go on.

In the lower-level fluidized shelves 10, at the position separated from the starting end by the length of one transported object 30, the transported object 30 that has left the movable shelf 7 reaches (or passes) and stays there. The above-mentioned detector 24 is installed as a sensor means for detecting the presence or absence. When the detector 24 detects a signal to detect the transported object 30 and the detector 13 of the movable shelf 7 generates an OFF signal indicating that the transported object does not exist, the pneumatic cylinder 17 starts the extension operation, and the The movable rack 7 is tilted to a position where it is connected to the upper fluid rack 9.

An empty transported object that slides down on the lower flow shelf 10 is temporarily stopped by a stopper (not shown) at the end, or slides down as it is and transferred to a separately prepared conveyor to accommodate assembly parts and the like. After sorting the items, they go to the place where they are stored, and after the storage, they are circulated back to the gravity type flow shelf device 1 again by a conveyor or the like. However, even when the worker is in the above-mentioned state until the empty transport object stays on the lower flow shelf 10 and the detector 24 of the same flow shelf issues an off signal indicating that there is no transport object. Even if the completion button 12 is pressed and a signal is input, the pneumatic cylinder 15 does not start the contraction operation, and the automatic control system is configured to stand by at the position until the lower fluid shelf 10 becomes empty.

Linkage control of the above-mentioned detectors 13 and 24 and the two pneumatic cylinders 15 and 17, and linkage control between the first and second stoppers 19 and 22 and the detectors 13 and 14 in the upper fluid shelf 9. In addition, a control box 11 that centrally and automatically controls the connection between the detector 24 of the lower fluid shelf 10 and the pneumatic cylinders 15 and 17 is installed in the lower portion of the shelf frame 3 (FIG. 1). When the power of the control box 11 is turned on, the detector 13 first detects that there is no object 30 to be transported on the movable shelf 7. The pneumatic cylinder 17 expands based on the detection signal, tilts the movable rack 7 to the position of → in FIG. 2, and connects it to the upper flow rack 9. Further, the pneumatic cylinder 15 operates to contract, and the inner frame 8 is tilted downward to the position of → in FIG. The first stopper 19 of the upper fluid shelf 9 is projected and waits for the arrival of the transported object 30, while the second stopper 22 goes down and escapes, and the transported object 30 is loaded above the fluidized shelf 9. Wait for

The gradient of the lower fluid shelf 10 is, as shown by the two-dot chain line 10 ′ in FIG. 1, the upper fluid shelf 9 and the upper fluid shelf 9 to the extent that the empty transported object 30 slides down by gravity. A configuration in which the floors are installed at a gentle gradient to the same extent and thus the floor height H at the right end of the upper flow shelf 9 is reduced as much as possible to facilitate the work of loading the transported objects 30 to the right end side of the flow shelf 9. It is also preferable to carry out. In this way, the lower fluid shelf 10 and the movable shelf 7 and the inner frame 8 of the turning mechanism 6 are connected with a slight bending angle, and the spindle 4 is located at the intersection of the upper and lower fluid shelves 9, 10. Although it is difficult to say, the interval L between the left ends of the upper and lower fluidized shelves 9 and 10 can be secured as large as possible to obtain a structure that is advantageous in changing the direction of the tall transported object 30. It is convenient.

[Effects of the present invention]

 The turning mechanism 6 of the gravity-type fluidized shelving device 1 according to the present invention not only receives and changes the direction of the transported object 30, but also faces the front of the worker standing along the assembly line, and also the worker. Since the support is supported by tilting the contained items such as assembled parts contained in the transported object at an angle that is easy to take out, unnecessary work of the worker and a difficult posture are not required, the work burden is reduced, and the work efficiency is improved. Contribute to.

When the empty conveyed object 30 is discharged from the rolling mechanism 6, the inner frame 8 is transferred to the movable shelf 7 that is connected to the lower flow shelf 10 in advance. The transported object 30 is handed over to the movable shelf 7, and the transported object 30 slides down on the roller-conveyor 7a of the movable shelf 7 due to the action of gravity and is discharged to the lower fluidized shelf 10. There is no inconvenient downhill, and there is no problem that the transported object 30 collides with the shelf frame or the floating shelf and the transported object is stagnant or damaged.
