Description

Detailed Description of the Invention (a) Field of Industrial Application The present invention relates to a container transfer/rotation device that transfers and inputs a fluid by raising and lowering a container in which the fluid is stored. It becomes possible to introduce the fluid into a container at a fixed position to receive it without leaking the fluid.

(B) Prior Art Conventional container transfer and rotation devices generally lack a reversing arm as shown in FIG. In some cases, the fluid container 35 is rotated and tilted around a clamper tilt shaft 32 provided at approximately the center of the fluid container 35 at the upper stop position, and the storage container is moved to a location corresponding to the input path to receive the fluid container.

In this method, after the fluid container 35 is raised, another storage container is moved to the empty space at the bottom to receive the fluid, but the fluid flow at the start and end of the fluid flow is different. In order to follow the momentary changes in the outflow path of the fluid content due to changes in the inclination angle of the body container 35, use a container with a large opening, or move the container as appropriate to receive the liquid.
This required a tedious task.

Another example, which will be explained with reference to FIG. However, there was one in which the fluid container 35 was tilted and reversed by the rotational angle of the reversing arm while being vertically reversed without changing.

In this method, if the size of the container and the length of the reversing arm are appropriate, the fluid container 35 can be expected to move in the horizontal direction as the arm is reversed, so it is not necessary to move the container 38 to be loaded each time. You may also be able to get away with it. However, if the fluid container 35 has a large amount of content, it will begin to flow out soon after the reversing arm 23 starts tilting, and the fluid container will have to be tilted considerably at the end of the flow. Changes greatly.

Therefore, the caliber of the container to receive the fluid must be quite large, but if the space for movement of the fluid container is taken into account, there will be restrictions on the size of the container.

In order to solve the above-mentioned problems of the prior art, some devices have been designed to increase the degree of freedom by attaching wheels to the container transfer/rotation device itself and moving the entire device to alleviate constraints.

In any case, considerable trials and careful driving are required.
Work efficiency was also extremely low.

(c) Problems to be Solved by the Invention As mentioned above, in the conventional technology, the reversal movement of the fluid container is performed around one central axis near the container, or is performed integrally with the rotation of the reversal arm. Therefore, there is a possibility that the fluid content may flow out at the same time as the fluid container begins to tilt, and as the capacity decreases and the end of charging approaches, it becomes necessary to increase the tilt angle of the fluid container. As the inclination angle of the reversing arm or the container itself increases, the vertical and horizontal distances of the outflow origin of the liquid content change.

Therefore, unless the diameter of the receiving container is very large, it is necessary to gradually move the position of either the device itself or the container.

The present invention facilitates such a nerve-wracking, complicated and inefficient operation, and the rotation of the reversing arm provides optimal movement of the transfer space to the receiving container necessary for loading the contents of the fluid container. Even if the reversing arm rotates, the opening of the fluid container always faces upward until it reaches the appropriate position to start dispensing, so there is no fear of spillage, and each movement of raising, lowering, reversing, and tilting the container can be freely performed. The purpose is to enable automatic transfer operation based on a sequence program.

(d) Means for Solving the Problems The present invention provides a container transfer/rotation device for holding, lifting, lowering, and rotating a container having an open top and containing a fluid. is provided with a reversing arm in which the reversing arm is rotated, and a clamper unit that is rotatably attached to the self-contained end of the reversing arm and holds the container; The means are characterized in that they are individually provided.

(E) Function In the present invention, since the turning drive means for the reversing arm and the rotation driving means for the clamper unit that holds the container are provided separately, the content fluid can flow out at the same time as the reversing arm starts rotating. Even if the reversing arm rotates, the opening of the fluid container is always kept facing upward until the required position, and the fluid container is moved appropriately through the required transfer space.
Regardless of the amount of remaining fluid content, it is possible to easily and efficiently charge the fluid into the storage container through an ideal charging route. Therefore, automatic sequence control is also possible.

It can be fixed by sandwiching it between the clamper arms 37 and 37. Instead of the manual tightening mechanism 36, a hydraulic cylinder may be used to hold the container 35 under pressure from both sides.

Note that the clamper unit 34 may be detachably attached to the reversing arm 23 so that clamper units of different shapes and structures can be attached to the reversing arm 23 depending on the form of the container 35.

The reversing arm rotation drive device includes an arm reversing gear motor 15, a reversing arm rotation shaft, and a reversing arm 2.
3. A system consisting of a pillow block 31, 31, a sprocket and a roller chain that connect and drive these, and the clamper unit tilt drive device includes a gear motor 16 for tilting the clamper, a clamper tilt drive shaft 20, a clamper tilt shaft 32, This refers to a system consisting of the clamper unit 34 and a sprocket and roller chain that connect and drive the clamper unit 34. The entire configuration described above forms the elevating unit 2.

Next, the operation of this device subjected to the FV# command as described above will be explained. This type of device generally transfers a container 35 placed on the floor by holding it under pressure with a clamper arm 37, 37, or transfers fluid into a container that is inseparably integrated with the clamper arm. It was transported after being loaded.

In an embodiment according to the invention, a container filled with a liquid content is first positioned between the clamper arms 37.37, the clamper arms 37.37 are closed so as to touch each other from both sides, and the open ends are closed using a manual tightening mechanism 36. Connect and tighten firmly at the same time.

The subsequent operation of the device may be performed by sequentially operating the control levers or switch buttons for each function, and visually controlling the operating position so that each function reaches a predetermined transfer position or angle, or by using a sequencer or the like to control these operating positions. The program may be stored and set to enable automatic operation.

Furthermore, the lifting/lowering unit 2 can detect the stop position of lifting/lowering, reversing/tilting, etc. using a pre-adjusted limit switch, proximity sensor, photocoupler, etc.
As mentioned above, the clamper unit 34 and the reversing arm 2
3, and a drive device for controlling these angles are integrated. When the lift button (10 shown in the figure) is pressed, the output shaft of the lift gear motor 7 moves counterclockwise ( Fig. 3) rotates and moves up and down small sprocket 8
And the vertical drive large sprocket 6 rotates counterclockwise. At this time, the rotation of the sprocket shaft is decelerated, and instead, the driving torque is increased and transmitted.

In response to this driving rotation, the upper and lower lifting sprockets 3, 36
Rotating counterclockwise, the lifting unit 2 is raised by the lifting roller chain 4 and the upper lifting roller chain joint 5.

The lifting unit 2 holds the container 35 while keeping the inclination angle of the reversing arm 23 constant, rises from the position A to the position B in FIG. 2, and stops at the pre-adjusted detection point of the upward expansion proximity switch. .

Next, when the arm reversal button (not shown) is pressed, the gear art motor 1 for arm reversal will appear in Figures 3 and 4.
5 rotates clockwise when viewed from the output shaft side, and is decelerated through the arm reversing small sprocket 24 and the arm reversing roller chain 25, increasing the driving torque to rotationally drive the arm reversing large sprocket 22.

This driving force is transmitted to the reversing arm rotation shaft 19, causing the reversing arm 23 to rotate counterclockwise in FIG. Stop at.

During this time, the gear motor 1 for tilting the clamper unit
6 is not driven to rotate, but is fixed to the small clamper tilt sprocket 29, the clamper tilt roller chain 30, the large clamper tilt sprocket 27, the clamper tilt drive shaft 20, and the clamper tilt roller chain 30.

However, as the inclination angle of the reversing arm 23 changes, the center position of the parallel operating sprocket 28 fixed to the clamper tilt shaft 32 moves from position B to D in FIG. Since the operating sprockets 28 have the same number of teeth (strictly speaking, pitch inner diameter) and are connected by a parallel operating roller chain 33, they always act like a so-called parallel link, and the clapper tilt shaft 32 is always connected regardless of the angle change of the reversing arm 23. does not produce a rotation angle with respect to the ground. Therefore, the clamper unit 34 does not tilt, and therefore the container 35 moves with the opening facing upward.

Next, when the clamper tilt button (not shown) is pressed, the clamper tilt gear motor 16 rotates clockwise when viewed from the output shaft side, and the clamper tilt small sprocket 29 and the clamper tilt gear motor 16 rotate as shown in FIGS. The speed is reduced through the roller chain 30, the driving torque is increased, and the clamper tilt large sprocket 27
This driving force that rotates the clamper tilt drive shaft 2
Parallel acting sprocket 2 fixed to the shaft end
8 in the counterclockwise direction when viewed from the right side of FIG.

Along with this, the parallel action sprocket 28 fixed to the clamper tilt shaft 32 connected by the parallel action roller chain also rotates in the same direction, and the clamper tilt shaft 3
2. The clamper unit 34 and the container 35 are integrally rotated and tilted counterclockwise in FIG. This rotary movement stops at a detection point of a preset rotation limit proximity switch. Due to this clamper tilt movement, the fluid content in the container 35 is moved to the storage container 3 installed at a predetermined position.
8 (Figure 2).

When the container 35 is emptied, the device goes through the reverse sequence of operations described above, and the fluid container 35 returns to the floor.
The aircraft lands on the ground and completes one transfer and injection.

Here, in FIG. 2, after the rising process, the reversing arm 2
3, and after stopping at point D, the tilting process (tilting) of the clamper unit 34 and container 35 begins. It is also possible to start rotating the geared motor 16 for tilting the clamper in parallel with the reversing process (for example, from point 0), thereby overlapping the tilting processes.

Moreover, if the operation is controlled by a sequence program, it is also possible to control by the operating time of each process instead of detecting each stop point by a proximity switch.

Needless to say, a power supply line and a signal circuit line for driving the motor are flexibly wired to the elevating unit (not shown) so that the elevating unit can follow the elevating movement.

In addition, in an appropriate space on the side of the mast or near the base! A panel, operation panel, sequencer, etc. are installed (not shown).

In one embodiment of the invention, parallel acting sprockets 28, 2
8 and the parallel operating roller chain 33 are arranged inside the reversing arm 23 for the purpose of safety and compactness, but the functions can be satisfied even if they are arranged outside along the reversing arm 23.

Further, in one embodiment of the present invention, the arm reversing large sprocket 22 is attached to the left end of the reversing arm rotation shaft 19, but the function will also be satisfied even if it is attached to the base of the reversing arm 23 at the right end of the reversing arm rotation shaft. FIG. 6 shows an example of how the device according to the present invention is installed. Figure 6 (a
), in order to make the installation of the mast 1 more solid, the upper flange 102 integrated with the mast 1 is fixed to the ceiling 101 with bolts, and the lower flange 42 fixed to the floor 103 is combined with the upper flange 102 to make the upper and lower is fixed.

In the device shown in FIG. 6(b), the entire device is rotatable around a vertical axis. That is, the mast bearing housings 105 and htaku are welded and fixed to the upper and lower ends of the mast 1, the radial bearing is inserted into the upper part, the thrust bearing 106 is inserted into the lower part, and the upper part is equipped with the mast rotation shaft 104 to which the radial pair rig is pivoted. The upper flange 102 fixed by welding is attached to the ceiling 101 with bolts, and the lower part is attached with a lower mast rotating shaft (not shown) to which the thrust bearing 106 is pivoted, and the lower flange 42 fixed by welding is attached to the floor with bolts. It is rotatable, further increasing the freedom of movement of the entire device.

The one shown in FIG. 6(C)# is a device that allows the entire apparatus according to the present invention to be moved on the floor.A lower frame integrated with a mast 1 has a fixed ring 107 and a caster wheel 108. There are two of each, but on the front side,
One each is attached to an outrigger 109 projecting from a cross member 110 so that the movement of the fluid container 35 is not hindered.

(G) Effects of the Invention In the present invention, since the turning drive means for the reversing arm and the rotation drive means for the clamper unit holding the container are provided separately, the two-dimensional path for transporting the container and the loading There is no need for initial leakage from the container that occurs because the angle of inclination of the container is not independent, and there is no need to move the storage container each time the container is loaded and make fine adjustments during the loading operation.

Furthermore, with the adoption of parallel acting sprockets, the structure is simple,
As long as the rotation of the gear motor for tilting the clamper is stopped, the opening of the container can always be directed upward, regardless of other operations.

Therefore, it is possible to efficiently transfer and put in containers without having to worry about operating the device, and without requiring any skill even in containers with small openings.

If the operation is controlled by a program using a sequencer, it is possible to make the system even more effective.
