[0001] The present invention relates to a turntable device. [Background technology]

[0002] 2. Description of the Related Art In factories and logistics centers, finished products and intermediate products are packed in fixed units into box-shaped containers such as containers and pallets, and then transported a fixed distance by a transport device such as a lift or a dolly.

[0003] In this case, empty containers, etc. are placed near the processing equipment using a transport device, and then the empty containers, etc. are set at a designated position immediately adjacent to the processing equipment by human power or a transport device. After the finished products and intermediate products discharged from the processing equipment are loaded into the containers, etc., the filled containers, etc. are moved by human power or a transport device to the removal location, and then removed by the transport device. Summary of the Invention [Problem to be solved by the invention]

[0004] In the process of moving empty containers, etc. from the location where they were transported by a conveying device to a designated location immediately adjacent to processing equipment and setting them there, and in the process of moving filled containers, etc. to an unloading location, it is difficult to move containers, etc. to a precise location quickly.

[0005] Furthermore, if the orientation of a container or the like changes during transportation, it becomes necessary to correct the orientation of the container or the like when transporting it using a transport device, resulting in the problem of extra work.

[0006] SUMMARY OF THE PRESENT EMBODIMENTS An object of the present invention is to provide a turntable device capable of moving an object such as a container while keeping the object oriented in a fixed direction. [Means for solving the problem]

[0007] In order to solve the above problem, the present invention provides a vehicle speed control system having a frame with a first gear, a second gear having the same number of teeth as the first gear and meshing with the first gear, and a third gear having the same number of teeth as the second gear and meshing with the second gear, the lower rotating member being rotatably provided with the second gear and the third gear being rotatably provided with the lower rotating member being rotatable with respect to the base; an upper rotating member that rotates together with the third gear and on which an object can be placed is provided rotatably relative to the lower rotating member; The lower rotating member is rotated relative to the first gear around the axis of the first gear, thereby rotating the upper rotating member while keeping the ornament oriented in a fixed direction in a plane perpendicular to the axis of the first gear.

[0008] Also, the first gear may be fixed to the base, and the lower rotating member may be rotated by a drive unit from the outside in the circumferential direction of the lower rotating member.

[Figure 4] FIG. 2 is a diagram showing the relationship between the first gear, the second gear, the third gear, the drive gear, the lower rotating lower plate, and the meshing members. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a turntable device according to the present invention will be described with reference to the accompanying drawings.

[0014] [Example 1] FIG. 1 is a top view of a turntable device 1 according to a first embodiment of the present invention, FIG. 2 is a schematic cross-sectional view of FIG. 1, and FIG. 3 is a left side view of FIG.

[0015] As shown in Figs. 1 to 3, the turntable device 1 has a platform 2 serving as a substantially horizontal base, and a first gear 3 is fixed to the center of the platform 2 and protrudes upward.

[0016] A lower rotating member 5 is provided on the upper side of the stand 2 so as to be rotatable relative to the first gear 3 around the axis of the first gear 3 .

[0017] 4, three second gears 6 are disposed around the first gear 3 in the circumferential direction about the axis of the first gear 3 at 120° intervals, and are rotatably provided with respect to the lower rotating member 5. Each second gear 6 is provided to mesh with the first gear 3, but the second gears 6 do not mesh with each other.

[0018] The number of teeth of each of the second gears 6 is configured to be the same as that of the first gear 3.

[0019] 4, third gears 8, the centers of which are located on the lines connecting the centers of the first gear 3 and the second gears 6, are provided rotatably relative to the lower rotating member 5, and there are three third gears 8 in total. Each third gear 8 is provided so as to mesh with only one second gear 6 located inside it.

[0020] The lower rotating member 5 has a lower rotating upper plate 5a at its upper end and a lower rotating lower plate 5b at its lower end, and each of the second gears 6 and each of the third gears 8 are rotatably sandwiched between the lower rotating upper plate 5a and the lower rotating lower plate 5b.

[0021] 2, the rotation shaft 8a of the third gear 8 is provided so as to protrude upward from the lower rotating top plate 5a. The upper surface of the first gear 3 is positioned above the lower rotating top plate 5a. A circular opening 5c ​​is formed in the center of the lower rotating top plate 5a.

[0022] The number of teeth of each of the third gears 8 is configured to be the same as that of the first gear 3.

[0023] 1 and 2, a plurality of meshing members 12 that mesh with the drive gear 11 that constitutes the drive unit 10 are provided on the outer circumferential surface of the lower rotating member 5. In this embodiment, the meshing members 12 are configured by winding a chain around the outer circumferential surface of the lower rotating member 5, but they can be configured by any member such as a gear as long as they can mesh with the drive gear 11. For example, they can be configured by providing teeth on the periphery of the lower rotating member 5.

[0024] A table-shaped upper rotating member 15 is fixedly provided above the lower rotating member 5 and on the upper end of the rotation shaft 8a of each third gear 8. The upper rotating member 15, together with the third gear 8, is provided so as to rotate relative to the lower rotating member 5 around the rotation shaft 8a of the third gear 8. A total of three upper rotating members 15 are provided.

[0025] A roller conveyor 17 is provided on the upper side of each upper rotating member 15 and is fixed to the upper rotating member 15. The roller conveyors 17 provided on each upper rotating member 15 are provided so that the movement directions of objects 18 placed on the upper side thereof are all the same. That is, as shown in Figures 1 and 3, the objects 18 placed on the upper rotating member 15 are oriented in a fixed direction (the up and down direction of the paper in Figure 1) in a plane perpendicular to the axis of the first gear 3.

[0026] The roller conveyor 17 is provided at an incline such that one end 17a in the direction of movement of the placed object 18 is lower than the other end 17b. The roller conveyors 17 are all configured to incline in the same direction.

[0027] A positioning portion 19 is provided at one end 17a of the roller conveyor 17 in the direction in which the object 18 moves.

[0028] Note that the load 18 can be configured in any shape as long as it can be placed on the roller conveyor 17. However, in order to make the load 18 easy to move by a transport device such as a lift, it is preferable to configure it as a box-shaped container such as a container or a pallet, as shown in Figs. 2 and 4, and to provide an insertion section for the forks of the transport device such as a forklift on its floor.

[0029] As a result, when an object 18 is placed on the roller conveyor 17, the object 18 moves toward one end 17a due to its own weight and then comes into contact with the positioning portion 19, and the object 18 stops at a predetermined position relative to the upper rotating member 15.

[0030] A driving unit 10 is provided on the lower rotating member 5 radially outward from the center of the first gear 3. The driving unit 10 has a driving gear 11 that is rotated by driving means (not shown). The rotation speed, rotation amount, etc. of the driving gear 11 can be changed by the driving means.

[0031] Next, a method for rotating each of the upper rotating members 15 of the turntable device 1 will be described.

[0032] When the driving gear 11 is rotated by the driving means of the driving unit 10, the meshing member 12 meshing with the driving gear 11 rotates, and the lower rotating member 5 rotates relative to the first gear 3. This causes the second gear 6 meshing with the fixed first gear 3 and the third gear 8 meshing with the second gear 6 to rotate. Then, together with each third gear 8, each upper rotating member 15 also rotates.

[0033] By making the first gear 3, second gear 6, and third gear 8 all have the same number of teeth, the lower rotating member 5 always faces a fixed direction. In other words, as shown in Figures 1 and 3, the lower rotating member 5 and each upper rotating member 15 can be rotated with an object 18 placed on the roller conveyor 17 always facing a fixed direction.

[0034] Next, a method of using the turntable device 1 will be described.

[0035] The turntable device 1 is installed in a manufacturing factory and used. First, the rotation of the drive gear 11 of the drive unit 10 is stopped so that each upper rotating member 15 is located at the first predetermined position 21, the second predetermined position 22, and the third predetermined position 23. No object 18 is placed on the upper rotating member 15 located at the first predetermined position 21.

[0036] Next, a carrying operation is performed in which the object 18 is placed on the roller conveyor 17 of the upper rotating member 15 located at the first predetermined position 21 from the other end 17b side of the roller conveyor 17 in the moving direction of the object 18. When the engagement between the carrying device and the object 18 is released, the object 18 moves toward one end 17a of the roller conveyor 17 due to its own weight, and then comes into contact with the positioning part 19 and stops at the predetermined position.

[0037] Next, the drive gear 11 is rotated by the drive means of the drive unit 10, the lower rotating member 5 is rotated by 120 degrees, and the upper rotating member 15, which is positioned at the first predetermined position 21, is moved to the second predetermined position 22, and the drive means of the drive unit 10 is stopped.

[0038] Next, the work of packing the placed object 18 with finished products or intermediate products is performed. After this work is completed, the drive gear 11 is rotated by the drive means of the drive unit 10, the lower rotating member 5 is rotated, and the upper rotating member 15 located at the second predetermined position 22 is moved to the third predetermined position 23, and the drive means of the drive unit 10 is stopped. This makes it possible to keep the position of the placed object 18 on the upper rotating member 15 constant and to make the position reference the same.

[0039] Next, the object 18 placed on the roller conveyor 17 of the upper rotating member 15 located at the third predetermined position 23 is removed from the other end 17b side of the roller conveyor 17 in the direction of movement of the object 18 by a transport device such as a lift, and a removal operation is performed to remove the object 18 from the upper rotating member 15.

[0040] Next, the drive gear 11 is rotated by the drive means of the drive unit 10, the lower rotating member 5 is rotated by 120 degrees, and the upper rotating member 15, which is positioned at the third predetermined position 23, is moved to the first predetermined position 21, and the drive means of the drive unit 10 is stopped.

[0041] In the same manner as above, the lower rotating member 5 is rotated to continue the work.

[0042] In this way, while the work of packing finished products and intermediate products onto the load 18 is being carried out at the second predetermined position 22, the loading work at the first predetermined position 21 and the unloading work at the third predetermined position 23 are being carried out simultaneously, so that each work can be carried out efficiently.

[0043] In addition, since the placed object 18 faces a fixed direction when performing each operation, there is no need to change the orientation of the placed object 18 during carrying-in and carrying-out operations, etc., and work efficiency can be improved.

[0044] [Example 2] In the above-mentioned first embodiment, the first gear 3 is fixed to the stand 2, but the first gear 3 may be rotated by a driving means to rotate the lower rotating member 5.

[0045] In the above embodiment 1, the number of each of the first gear 3, second gear 6, third gear 8, and upper rotating member 15 is three, but the number of each of the first gear 3, second gear 6, third gear 8, and upper rotating member 15 can be set to any number as long as they are the same. It is preferable that the number of each of the first gear 3, second gear 6, third gear 8, and upper rotating member 15 is three or more.

[0046] The other configurations and structures are the same as those in the first embodiment, and therefore the description thereof will be omitted.

[0047] In the second embodiment, the same actions and effects as those of the first embodiment are achieved.

[0048] [Example 3] In the above-mentioned Examples 1 and 2, the turntable device 1 was installed in a manufacturing plant, and loading operations were performed at the first position, the operation of loading products or intermediate products onto the load 18 was performed at the second position, and the operation of removing products was performed at the third position. However, the turntable device can be used in various places other than manufacturing plants, such as automobile inspection centers.

[0049] For example, the turntable device 1 may be installed in a manufacturing plant and used to perform an loading operation of loading an unprocessed product onto the upper rotating member 15 at a first position, an operation of removing an unprocessed product from the load 18, processing it in processing equipment, and returning it to the load 18 at a second position, and an operation of removing the processed product or finished product at a third position.

[0050] Also, for example, the turntable device 1 may be used in such a way that the turntable device 1 is installed at an automobile inspection center or the like, and an automobile is received at a first position and placed on the upper rotating member 15 for an acceptance operation, the automobile on the upper rotating member 15 is inspected, serviced, washed, etc. for an acceptance operation at a second position, and the automobile is received after inspection, service, etc. are completed at a third position.

[0051] The other configurations and structures are the same as those of the first and second embodiments, and therefore the description thereof will be omitted.

[0052] In the present embodiment, the same actions and effects as those in the first and second embodiments are achieved. [Explanation of symbols]
