DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drum liquid metering and charging apparatus for metering a liquid filled in a container such as a drum can and charging the liquid into another container in a state in which the liquid is not scattered.

[0002]

2. Description of the Related Art Conventionally, when various liquids are supplied into a storage tank such as a reaction tank or a tank, a method in which a small variety of liquids are supplied in large quantities for each liquid has been adopted. Was something. However, in recent years, the demand has been diversified, and a method of introducing a large variety of liquids little by little for each liquid has been adopted. In this case, the supply means by piping was inefficient.

To solve this problem, Japanese Utility Model Publication No. Sho 60-2436 discloses a means for lifting a container such as a drum filled with liquid, turning it, turning it upside down, and putting it into a container such as a reaction tank or a tank. However, in this case, since there is no means for measuring the drums, the charged amount is measured by eye measurement or experience, so that an error occurs in the charged amount.

[0004] As means for solving this, Japanese Patent Application No. Hei 2-26 is disclosed.
No. 8454 (JP-A-4-145330) is provided. In this device, the drum can 1
A plurality of roller groups consisting of a motor roller 9 and a free roller 10 arranged on both sides on the upper surface of the lifter 3 are erected and mounted.
Are rotated by motor rollers 9 arranged alternately,
The direction and the overall position of the discharge nozzle 26 are determined.

A semicircular drum receiver 7, 7 'is fixed between the upper and lower supports 8, 8' in an upright state, and a drum receiving rod 16 is provided between the distal ends of the lower drum receiver 7 '. . At the lower ends of the supports 8, 8 ', drum receiving plates 17, 17' are provided at the same level as the drum receiving rod 16, and at the upper portions of the supports 8, 8 ', a drum holder for supporting only the drum can 1 is provided. 22, 22 'are provided.

A motor 20 capable of rotating a worm 31 via a speed reducer 21 is provided above the columns 6, 6 ′ standing on the weighing table 4 on both sides of the drum can 1. A worm wheel 32 that can mesh with the worm 31 is provided at both ends of the worm.

To charge the liquid in the drum 1,
First, the lifter 3 is lowered to move the container 1 to the drum receiving rod 1.
6 and the drum receiving plates 17 and 17 'are supported at three points, and the upper rim of the container 1 is supported by drum holders 22 and 22'. In this state, the motor 20 is driven to drive the worm 3
When the worm wheel 32 is rotated by 1, the drum can 1 can be turned over in the direction of the discharge nozzle 26 around the axis of the worm wheel 32, and the liquid is charged into a container such as a reaction tank or a tank according to the overturn angle. . Since the input amount is measured by the weighing table 4, when the input amount reaches a predetermined amount, the container 1 is turned upside down by driving the motor 20 and stands up, and is placed on the lifter 3.

[0008]

In the above-mentioned apparatus, the drum container 1 is turned over to the discharge nozzle 26 side and the liquid is introduced into another container. The drum container 1 is always measured by the measuring table 4. Therefore, there is an advantage that the injection accuracy is high.

However, since the plurality of motor rollers 9 have independent drive sources for controlling the rotation and stop of the individual rollers 9, it is necessary to control all the drive sources synchronously. Was complicated, and the weight of the entire lifter 3 was heavy.

When the liquid is introduced, the container 1 is turned over. Since the center of rotation of the container 1 is turned around the axis of the worm wheel 32, the center of rotation of the container 1 and the position of the center of rotation of the nozzle 26 are shifted. When the liquid was dropped and the liquid was supplied while falling, the nozzle 26 had a large moving angle and the liquid was scattered greatly. For this reason, there is a problem that the scattered liquid contaminates the entire apparatus, and the reaction tank, tank, etc. on the side into which the liquid is introduced and the surroundings are also contaminated by the liquid.

In view of the above-mentioned problems of the conventional metering and charging apparatus, the present invention reduces the rotation angle of the nozzle by bringing the center of rotation of the drum container close to the liquid discharge nozzle, and eliminates or temporarily disperses the liquid. It is an object of the present invention to provide a drum liquid metering / injection device in which the scattering range is extremely small even if there is any.

[0012]

In order to achieve the above object, according to the present invention, a turning mechanism 3 is provided on a support base 1 via an aligning mechanism 2 and a measuring device 17, and the aligning mechanism 2 has a rectangular shape. On the upper surface of the frame 5, a pair of rollers 6 and 7 are provided on both sides along the transport direction of the container A such as a drum filled with liquid, and one of the rollers can be forcibly rotated left and right while the other is rotated. The roller group is capable of free rotation in one direction and forcibly rotating in the other direction together with the roller group.

The position of the provided liquid discharge nozzle 15 can be detected, and a stopping mechanism for the container A is provided.

The other rotary drive mechanism of the pair of roller groups 6 and 7 is such that the roller group 6 is rotatable in the direction of rotation of the drive motor 13 via the drive shaft 12 and the roller group 7
Connects a universal joint 43 provided at the tip of the drive shaft 12 directly to a gear 44 on one side of a pair of horizontally movable gears 44, 45, and a gear 47 directly connected to a rotating shaft 46 of the roller 7a. Reference numeral 45 indicates that the roller group 6 can be alternately engaged with the roller group 6 so as to be capable of normal and reverse rotation.

Of the two roller groups 6, 7, one roller group,
For example, the roller group 6 can be forcibly rotated left and right by a sprocket 12a. The other roller group 7 is provided with a one-way clutch (not shown) on the sprocket 12b, so that the transport direction X of the container A idles, and the rotation in the opposite direction can be forcibly rotated by the drive shaft 12. is there. The roller groups 6 and 7 on both sides are at the same horizontal height position as the transport device 4, and the container A is carried into the alignment mechanism 2 from the transport device 4 and is transferred onto the roller groups 6 and 7.

The container A transferred onto the roller groups 6 and 7 on both sides is provided with the inertia of the transport speed from the transport device 4 and the roller group 6 forcibly rotating rightward in FIG.
As a result, the vehicle advances while being guided by the guides 14 on both sides, and stops at a predetermined position by a stop mechanism described later. If the rotation of the roller group 6 is continued at this stop position, the container A rotates counterclockwise in FIG.
5 is a roller group 6 at a position facing the liquid discharging direction on the right side of FIG.
Is stopped, and the container A is fixed.

The turning mechanism 3 is configured by erecting a support frame 16 combined in a square shape on the support base 1 via a measuring device 17, and the support frame 1, the support frame 16 and the measuring device 17 Are fixed individually. Four weighing devices 17 are installed at four corners of the support gantry 1, and FIG. 4 shows a fixed relationship between the support gantry 1, the support frame 16 and the weighing device 17 at a certain position.

That is, a square or circular measuring device 17
Is fixed to the support base 1, and the support frame 16 is fixed on the measuring sensor 18 of the measuring device 17 via the mounting plate 19. In this way, the three members are fixed, the support frame 16 is erected on the support gantry 1, and the load on the support frame 16 can be weighed through the weighing sensor 18.

On the upper side of the support frame 16, on the side of the container A in the turning direction, a turning shaft 20 is installed via a bearing 21 so as to be close to the upper part of the container A and orthogonal to the turning direction of the container A. is there. A servo motor 22 and a speed reducer 23 directly connected to the motor 22 are provided on one side of the upper surface of the support frame 16. One end of the rotating shaft 20 is connected to the speed reducer 23,
The speed reducer 23 can be rotated forward and backward by the driving force of the servo motor 22.

The upper ends of a pair of supports 24 disposed at an appropriate interval are fixed to and suspended from the turning shaft 20.
A hand 25 that is horizontal toward the direction of transport of the container A is attached to an intermediate portion of each support 24. Both hands 25
The circumferential side of the container A has a symmetrical shape that can be gripped from both sides, and the configuration and operation of one hand 25 will be described with reference to FIG.

The hand 25 has a gripping surface 26 curved along the circular outer periphery of the container A. A base 27 of the hand 25 is provided between two upper and lower support plates 28 projecting from the side surface of the support 24. A connecting plate 29 which is rotatably connected to the shaft and is horizontally provided at the tip of the base 27 is a rod 3 of a cylinder 31 which is mounted on a holding plate 30 which is provided between the two supports 24.
The two ends are rotatably connected to a shaft.

Since the hand 25 rotates in the horizontal direction around the base 27 by the expansion and contraction of the cylinder rod 32, when the rod 32 is pulled, the distal ends of both hands 25 expand outward and open. The container A transferred on the alignment mechanism 2 as described above is received between the gripping surfaces 26 of the two hands 25 in the open state. still,
In the figure, reference numeral 33 denotes a non-slip material having appropriate elasticity and frictional property, such as urethane rubber, provided on the gripping surface 26 of the hand 25.

The container A, which has been transferred from the transfer device 4 onto the roller groups 6 and 7 of the alignment mechanism 2 as described above and has reached between the open hands 25, is transferred onto the alignment mechanism 2 by the above-mentioned stopping mechanism. At a predetermined position. As shown in FIG. 6, the stop mechanism is provided on the support 24 facing the container A side.
A pair of roller stoppers 35 are provided on a plate 34 disposed therebetween, and the roller stopper 35 having elasticity such as rubber is rotatable in the horizontal direction. When the container A rotates on the roller groups 6 and 7, the body of the container A rotates in contact with the roller stopper 35 in the free state.

In FIG. 2, reference numeral 36 denotes a sensor.
The support frame 16 is provided symmetrically between the upper surfaces. The sensor 36 detects the position of the discharge nozzle 15 of the container A. The container A, which has been moved onto the alignment mechanism 2 as described above and has been stopped from moving forward by the roller stopper 35, is rotated in a horizontal state by the rotation of the roller group 6, and the position of the discharge nozzle 15 is changed by the sensor 36. When the discharge nozzle 15 is detected by the sensor 36, the drive of the motor 13 is stopped, and the container A is fixed at a predetermined position where the nozzle 15 faces right in FIG.

As the sensor 36, a light-transmitting or blocking light sensor can be used. The sensor 36 is merely an example, and the position of the discharge nozzle 15 may be detected by physical or mechanical operation.

After the direction of the discharge nozzle 15 is determined and the container A is fixed as described above, if the cylinder rod 32 is extended, both hands 25 move in the closing direction, and the gripping surface 26 becomes the outer body of the container A. , And the outer periphery of the container A is strongly gripped between the gripping surfaces 26 of the hands 25 on both sides and tightly wound. In this state, when the motor 22 is driven and the speed reducer 23 is operated, the rotating shaft 20 rotates rightward in FIG.

The upper ends of two supports 24 are fixed to the turning shaft 20, and a hand 25 connected to each support 24 is fixed.
Is holding the container A, so that the container A rotates with the support 24 and the hand 25 according to the rotation of the turning shaft 20.
It turns around 0. FIG. 7 shows the turning state of the container A in a stepwise manner. The nozzle 15 is directed downward as the container A turns, and the liquid flows out from the tip. Reference numeral 37 denotes a container such as a reaction tank or a tank which receives supply of a liquid.

The outflow amount of the liquid is measured by the measuring device 17. The measuring device 17 includes a support frame 16 and a rotating shaft 20 attached thereto, a motor 22, a speed reducer 23, a support 24 and a hand 25. Since the weight of the liquid is measured and stored in advance, the outflow amount of the liquid can be calculated by adding the weight of the container A filled with the liquid and calculating the whole.

When the outflow amount of the liquid from the container A which has been rotated and inclined approaches the predetermined amount, the motor 22 is stopped, and the rotation of the container A is stopped. As described above, the container A is stopped in a state where the container A is tilted in the turning direction, and thereafter, the motor 22 is rotated in the opposite direction to the above, and the outflow amount is adjusted while controlling the reverse rotation speed to adjust the outflow amount to the specified amount. . When the outflow amount reaches the specified amount, the container A is inverted in the opposite direction via the speed reducer 23 and the turning shaft 20, and is returned to the alignment mechanism 2, and the liquid supply operation is completed. That is, a certain amount of liquid flows out in the turning direction, and flows out until reaching a predetermined amount when rotating back in the stationary direction.

When both hands 25 are released, the container A is in a free state and stands on both roller groups 6 and 7. Motor 13
By rotating the two roller groups 6 and 7 in the left direction in FIG. 1 in synchronization with each other, the container A is moved to the transporting device 4 side, and is transported to an accumulation place or another charging device.

FIGS. 8 and 9 show another embodiment of the support 24. FIG. In this embodiment, supports 38 and 39 are horizontally provided at the upper and lower ends of both supports 24 in the same direction as the hand 25. Upper and lower supports 38, 39
Has a small gap between the containers A, the upper support 38 having an L-shaped cross section has a curved shape along the container A similarly to the hand 25, and the lower support 39 has a plate-like or rod-like shape. It is.

With the support 24 having the above structure, when the container A is gripped and turned by the hand 25,
If the gripping force of the hand 25 is weak and the gripping surface 26 and the container A slide, the upper surface of the container A is held by the support 38,
Further, when returning to the normal position, the lower support 39 receives the container A, so that the container A does not fall off the entire charging device and fall.

As shown in FIG. 9, if the transmissive optical sensors 40 and 41 are provided between the two supports 38, the nozzle 15 of the rotating container A can be used to detect both the sensors 40 # 40 and 41 #. When the liquid reaches the intersection point 41, that is, the liquid dischargeable position, this is detected, the drive of the motor 13 is stopped, and the container A can be fixed on the alignment mechanism 2.

Reference numeral 42 denotes a roller stopper provided in the side surface of both supports 38 facing the container A, which fixes the container A transferred on the alignment mechanism 2 at a predetermined position. Therefore, the roller stopper 42 has the same function as the roller stopper 35 used in the above-mentioned stopping mechanism, and the container A can be fixed if any one of the roller stoppers 35 and 42 is provided.

In the above description, the upper support 38
Has a curved shape that matches the outer shape of the container A,
It is not limited to this, as shown in FIG.
The support 38 may be a linear body.

FIGS. 11 and 12 show another embodiment of the rotary drive mechanism of the two roller groups 6 and 7, and the same reference numerals are used for the same parts as those in the above-mentioned embodiment. The drive mechanism according to this embodiment is directly connected to the motor 13 and
A pair of gears 44 and 45 connected side by side in the horizontal direction to the tip of the drive shaft 12 capable of driving the drive shaft 7 via a known universal joint 43 having flexibility and elasticity.
Out of the gears, for example, the gear 44 is fixed, and the gear 47 that can mesh with both gears 44 and 45 is fixed to the rotating shaft 46 of the roller 7a located at the end near the drive shaft 12 of the roller group 7. Has a basic configuration.

A pair of gears 44 and 45 are installed on a carriage 48, and the carriage 48 can be reciprocated by a cylinder 50 on a guide rail 49. Trolley 4
As the gear 8 moves, the gear 44 and the gear 47 or the gear 45 and the gear 47 mesh with each other at the up and down positions, and the universal joint 43 is extendable, so that the gear 44 moves from the linear position of the drive shaft 12 to the lateral direction. However, it can transmit torque.

Each roller forming the roller group 7 is rotatable by a gear 47. FIG. 13 shows a driving structure of the roller group 6. That is, two sprockets 8, 8a, 12c and 12d are respectively provided on the rotation shaft 51 and the drive shaft 12 of the roller 6a which is arranged in the axial direction with the roller 7a.
Is attached.

As described above, the sprocket 8 transmits rotation to the other rollers. The sprocket 8a is connected to the sprocket 12c of the drive shaft 12 by a chain, and the sprocket 12d is connected to the sprocket of the motor 13. is there. Each roller of the roller group 6 is rotatable in the same direction along the rotation direction of the motor 13, and the roller group 7 is rotatable in the normal and reverse directions by changing the engagement between the gears 44 and 45 and the gear 47.

A description will be given of a case where the container A is loaded into the aligning mechanism 2, a case where the container A is rotated, and a case where the container A is unloaded, in the above-described rotary drive mechanism of the roller groups 6 and 7. When the container A is carried into the alignment mechanism 2 from the transport device 4, the carriage 48 is moved in the direction of the cylinder 50 by the cylinder 50 as shown in FIGS.
5 and the gear 47 are meshed up and down. When the sprocket 12d of the drive shaft 12 is rotated by the motor 13 in the direction of the arrow Y (see FIG. 13), each roller of the roller group 6 rotates in the X direction for loading the container A. The roller group 7 is rotated via a gear 44 ギ ア a gear 45─a gear 47, and the rotation direction of the motor 13 is
, Each roller of the roller group 7 rotates in the same direction as the roller group 6. Therefore, the container A placed on both the roller groups 6 and 7 advances in the X direction, and is stopped at a predetermined position by the stop mechanism.

After the container A is set in place, FIG. 12 and FIG.
As shown in the figure, the carriage 48 is moved in the opposite direction to release the gears 45 and 47, the gears 44 and 47 are engaged with each other, and the roller group 6 is driven by the motor 13 to move the roller group 6 to the same X as described above. , The roller group 7 rotates in the opposite direction to the roller group 6.
The container A resting on 7 rotates counterclockwise in the horizontal direction.
If the sensor 36 or the sensors 40 and 41 detect the discharge nozzle 15 during the rotation, the rotation is stopped, and the rotation mechanism 3 rotates the container A as described above.

The container A that has finished discharging the liquid and returned to the alignment mechanism 2 is carried out and transferred to the transport device 4. For this reason, it is necessary to rotate the roller groups 6 and 7 in the direction opposite to the direction at the time of loading. If the sprocket 12d is rotated in the direction opposite to the arrow Y, the roller group 6 is taken out (to the left in FIG. 1).
To rotate. Then, as in the case of the above-described carrying in, the roller group 7 rotates in the same direction as the roller group 6 by meshing the gear 45 and the gear 47, so that the container A can be carried out.

FIGS. 16 and 17 show still another embodiment of the rotary drive mechanism of both roller groups 6 and 7, and the same reference numerals are used for the same parts as those in the above embodiments. In the present embodiment, the drive shaft 12 is divided, and the divided drive shaft 12 can be disconnected and connected by the clutch 52, so that the rotation of the roller group 7 is free in one direction and can be forcibly rotated in the other direction. It is characterized by doing.

More specifically, the drive shaft 12 divided into two parts is disposed concentrically in the longitudinal direction, one of which is supported on the frame 5 as a drive side and the other as a driven side by bearings. . The drive shaft 12e on the drive side is directly connected to the motor 13 as in FIG. 3, and the sprocket 8 of the roller group 6 and the sprocket 12a are connected by the chain 10. Further, the driven shaft 12f is connected to the rotating shaft of the roller 7a at the end of the roller group 7 and the gears 53 and 54.
As described above, the roller group 7 rotates by connecting the sprocket 9 of each roller with a chain 11.

The drive shafts 12e and 12f can be disengaged and connected by a clutch 52 provided at a divided end. A flange 52a on the drive shaft 12e side is formed by a spline shaft 55 formed at an end of the drive shaft 12e. Movable, drive shaft 1
The flange 52b on the 2f side is fixed. Flange 52
A cylinder 56 is used to make a movable. For this reason, a ring 57 is rotatably loosely fitted in an annular groove formed in the body of the flange 52a, and the ring 57 and the cylinder 56 are fixed via a rod 56a.

Therefore, the flange 5 is formed by the cylinder 56.
2a is advanced to the side of the flange 52b.
2a and 52b are connected and the driving force of the motor 13 is the driving shaft 1
It is transmitted to the drive shaft 12f side via 2e. Flange 52a
Rotates with the drive shaft 12e, but since the ring 57 is loosely fitted to the flange 52a, no rotational force is transmitted to the cylinder 56.

Next, the operation state when the container A is loaded, rotated and unloaded will be described. When the container A is carried in the X direction, the clutch 52 is shut off, the roller group 7 is set in the free state, and only the roller group 6 is forcibly rotated. It moves forward and stops at a predetermined position.

After the container A is fixed, the cylinder 52 moves the flange 52a to the flange 52b side along the spline shaft 55, and when the clutch 52 is connected, the roller group 7 can be forcibly rotated.
As a result, the roller group 7 is rotated in the opposite direction to the roller group 6, so that the container A is rotated in the horizontal direction by the reverse rotation of the roller groups 6 and 7, and the discharge nozzle 15 is detected by the sensor as described above. Then, the rotation of the roller groups 6 and 7 is stopped, and the rotation is started in the liquid discharging direction.

When the discharge of the predetermined amount of liquid is completed and the container A is fixed on the alignment mechanism 2 again, the clutch 52 is disconnected to set the roller group 7 in a free state, and only the roller group 6 is rotated to rotate the container group. A is moved in the direction of the transport device 4.

In the drawing, the case of the meshing clutch is shown as the clutch 52, but the clutch 52 is not limited to this, and a known friction clutch such as a plate clutch or a conical clutch may be used.
