Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a plan view of the entire apparatus of the present invention. Reference numeral 1 is a crane, and as shown in FIGS. 2 and 3, one side is grounded via wheels 2 and the other side is an elevated rail. The crane 1 is mounted on wheels 3 via wheels 4 and is capable of reciprocating along a fixed track in the (+) or (-) direction of the X axis. On the crane 1, a rail 5 is installed in a direction orthogonal to the X axis, and along this rail 5, the container transfer unit 6 has a Y axis (+).
Alternatively, it is installed so that it can reciprocate in the (-) direction.

There are a large number of distances within the range in which the crane 1 can reciprocate and the range in which the transfer section 6 can reciprocate, that is, the workable rectangular area of the transfer section 6 surrounded by the X and Y axes. A container 7 group and a powder processing unit 8 are arranged, and a hopper 9 for receiving the powder is installed near the powder processing unit 8 outside this space range.

The container 7 used in this embodiment is shown in FIG.
Further, as shown in FIG. 5, a screw-type lid 10 is provided on the upper surface, and four corners are formed in a rounded curve, and a recess 11 for carrying is provided at the center of the upper portion of each side.
It is made of a conventionally known plastic in which A plurality of containers 7 each containing powders having different content components are placed on a single pallet 12 in a vertically and horizontally aligned state, and such container groups are arranged in a plurality of rows along the moving direction of the crane 1. It is installed. Note that the lid 10 is not limited to the screw-in type, and for example, a one-touch rotary opening / closing type or a pressing opening / closing type lid used in a petroleum can can be used.

Since each container 7 has rounded corners as described above, when each container 7 is placed on the pallet 12 and aligned as shown in FIG. 6, the space between adjacent corners of the container 7 is reduced. A space 13 is formed in the space. Although FIG. 1 shows a case in which 16 containers 4 × 4 are placed on one pallet 12, the size of the pallet 12 or the container 7
The number of containers 7 placed on the pallet 12 can be arbitrarily selected according to the size of the.

The transfer unit 6 takes out necessary containers from a large number of containers 7 loaded on the pallet 12 and transfers them to the powder processing unit 8 or supplies powder to the hopper 9 in the powder processing unit 8. After that, the empty container 7A is transferred from the powder processing section 8 to the empty container installation place 14 provided in the vicinity of the container 7 group containing the powder in FIG. In addition, empty container setting place 1
4 is also within the space range surrounded by the X axis and the Y axis, and the empty container 7A is placed on the pallet 12.

The transfer section 6 is composed of a traveling section 15 and a hand section 16 as shown in FIGS. Running part 15
Is a portion for moving the entire transfer unit 6 in the Y-axis direction,
As shown in FIGS. 7 and 9, the pinion 19 that is horizontally mounted on the rail 5 of the crane 1 via the wheels 17 and that is directly connected to the reversible drive motor 18 is the rail 5 in the longitudinal direction. The rack 20 is meshed with the rack 20 installed integrally on the rail 5.

7 and 10 are provided on both sides of the long guide body 21 projecting along the length direction of the lower surface of the rail 5.
As shown in, the guide roller 22 rotatably installed in a horizontal state is provided in contact with the running portion 15. Therefore, if the motor 18 is driven to rotate the pinion 19, the pinion 19 moves while rotating along with the rack 20, and the traveling unit 15 and the hand unit 16 integrally connected thereto are separated. Because of the relationship between the guide body 21 and the guide roller 22, the guide body 21 and the guide roller 22 can move straight forward and backward in the Y-axis direction without lateral shake.

The hand portion 16 is integrally connected to the traveling portion 15 on one side surface of the rail 5, and the hand portion 1
Reference numeral 6 is composed of two hands 23 and 24 and one claw 25, and the entire hand portion 16 can be raised and lowered by a main cylinder 26. That is, the hands 23, 24 and the claw 25 are installed in a triangular shape on the lower surface of the horizontal holding plate 27 directly connected to the main cylinder 26, and the hand portion 16
The entire cylinder can be moved up and down by the main cylinder 26, and only the claw 25 is provided on the holding plate 27.
It is possible to move up and down independently. It should be noted that the two guide rods 29 guide the hand portion 16 so as not to cause lateral shake when the hand portion 16 is moved up and down.

As for the positional relationship between the hands 23 and 24 and the claw 25, as shown in FIG.
It is located below 5. Further, as shown in FIG. 11, the claw 25 is at a position where it can abut on the corner 7a of the container 7, and the two hands 23, 24 have the container corner 7a on which the claw 25 abuts. Since the container 7 is located at a position corresponding to both side surfaces in contact with the diagonal 7b, the container 7 can be held by being sandwiched between the claw 25 at the corner portion 7a and the hands 23 and 24 at the two side surfaces.

Next, a case where the container 16 on the pallet 12 is gripped by the hand portion 16 and transferred to the powder processing portion 8 will be described. The crane 1 is moved in the (+) or (-) direction along the X-axis direction, and the transfer unit 6 is stopped at a position corresponding to the container 7 aligned along the Y-axis. Next, the transfer section 6
Is moved along the rail 5 in the (+) or (-) direction of the Y-axis, and the transfer unit 6 is stopped on the predetermined container 7 on the pallet 12.

The positional relationship between the plurality of containers 7 on the plurality of pallets 12 and the content components of the powder contained in each container 7 are input and stored in a computer in advance, and the transfer unit 6 is read by the computer. The required container 7 can be selected by moving the X axis and the Y axis.

When the transfer unit 6 moves to the selected container 7 and stops, the hands 23 and 24 are moved to the recesses 1 on the two sides of the container 7 by lowering the hand unit 16 by the main cylinder 26.

The main cylinder 26 may be stopped by this sensor coming into contact with the upper surface of the lid 10 of the container 7 to detect it. Alternatively, since the height position of each container 7 and the transfer unit 6 is in a fixed state, it is possible to manage the lowered position of the transfer unit 6 by a computer.

After the hand portion 16 stops at the predetermined height position as described above, the sensor 30 attached to the hand 23 is moved by the cylinder 31 to the hand 23 as shown in FIG.
Forward, and in this state, the entire transfer unit 6 is moved in the Y-axis (−) direction (see FIGS. 3 and 8),
When the sensor 30 contacts the side surface of the container 7 and detects its presence, the movement is stopped.

At the time when the hand portion 16 descends and stops at a predetermined height position, the hand 24, as shown in FIG.
Although it is at a position displaced to one side with respect to the side surface of the container 7, the entire transfer unit 6 moves in the Y-axis (−) direction, so that FIG.
As shown in FIG. 1, the hand 24 is located at the center of the side surface of the container 7. At the same time, the claw 25 is located above the corner 7a of the container 7.

When both hands 23, 24 face the recess 11 formed on the side surface of the container 7 in this way, first the hand 2
The cylinder 3 advances by the cylinder 32, enters the concave portion 11, and stops. As shown in FIGS. 7 and 8, the hand 24 is installed on the lower surface of the holding plate 27 via a support plate 33, and the upper end of the support plate 33 slides horizontally with respect to the holding plate 27. The slide of the support plate 33, which is operably connected, is performed by a cylinder 34 attached to the lower surface of the holding plate 27.

In order to put the hand 24 into the recess 11 of the container 7, the sensor 35 attached to the hand 24 is advanced in advance to activate the cylinder 34 when the position of the container 7 is detected, and the support plate 33 is used. The hand 24 is moved toward the container 7 and the operation of the cylinder 34 is stopped when the hand 24 enters the recess 11. Next, when the claw 25 is lowered by the cylinder 28 until it comes into contact with the side surface of the corner 7a of the container 7, the container 7 is clamped at the triangular points as described above. Operations such as lowering and stopping the hand portion 16 by the main cylinder 26 and actuating and stopping the hands 23 and 24 and the claw 25 can be automatically performed in advance by computer control.

After selecting a predetermined container 7 from the group of many containers 7 as described above and gripping the container 7 with the hand portion 16,
The hand unit 16 is raised by the main cylinder 26 to a predetermined height position (a position higher than the containers 7 aligned on the pallet 12), and the crane 1 is moved along the X axis toward the powder processing unit 8. Let Transfer unit 6, that is, hand unit 1
When 6 reaches a position aligned with the powder processing unit 8, the crane 1 is stopped. Next, the transfer unit 6 is moved along the Y axis,
When the hand unit 16 (container 7) reaches a predetermined position above the powder processing unit 8, the transfer unit 6 is stopped.

The powder processing unit 8 described above has a mechanism for weighing the entire container 7 and automatically removing the lid 10 and reversing the container 7 to throw the powder, which is the content, into the hopper 9. Have Therefore, as shown in FIG. 1, FIG. 3 and FIG. 12, at the center of the pedestal 36 on which these mechanisms are installed, there is a transport device 37 such as a roller conveyor in a state parallel to the moving Y axis of the transfer unit 6. The transfer device 37 is installed in the middle of the transfer device 37, and a lid attaching / detaching part 38 of the container 7 after weighing is provided so as to straddle the transfer device 37. Container 7 after removing 10
An inverting section 39 of is provided.

The container 7 grasped by the hand portion 16 is lowered by the main cylinder 26 and placed on the rear end portion of the transfer device 37 of the powder processing portion 8 as shown in FIGS. For example, a sensor is attached to the transport device 37, and when the sensor detects that the container 7 is placed on the transport device 37, the hand unit 16 is operated to operate the hands 23, 2.
If the container 4 and the claw 25 are lifted away from the container 7 by the operation opposite to the above, the container 7 is independently placed on the transfer device 37.

After the container 7 is placed on the transfer device 37, the transfer device 37 is operated to feed the container 7 toward the lid attaching / detaching part 38, and stop the container 7 at a position below the attaching / detaching part 38. For the roller conveyor forming the transport device 37, a sprocket may be provided at one end of each roller, and a known drive mechanism may be used in which the chain hung on each sprocket is circulated by a motor. The transport device 37 is not limited to the roller conveyor, and may be, for example, two or a plurality of chain conveyors.

In order to stop the container 7 below the attaching / detaching part 38, at the same time as stopping the transfer device 37 itself, for example, a known stopper is projected from below or to the side of the transfer device 37 to move the container 7 to a predetermined position. You can stop at.

As shown in FIGS. 3 and 12, a known weighing machine 40 is installed below the carrying device 37 at a position corresponding to the attaching / detaching portion 38. The measuring device 40 can be moved up and down by a cylinder 41, and a supporting body 42 composed of four supporting rods or a pair of supporting plates is provided on the upper surface of the measuring device 40 so as to project therefrom. 37
It is possible to project above the transport device 37 through the space. Therefore, when the container 7 stops below the detachable section 38,
The scale 40 is raised by the cylinder 41, and the container 7 is lifted by the support body 42 to weigh.

After the container 7 is weighed, the scale 40 is lowered by the cylinder 41, the support 42 is retracted below the carrier device 37, and the container 7 is again placed on the carrier device 37. Next, the lid attaching / detaching portion 38 automatically removes the lid 10 of the container 7.

Details of the lid attaching / detaching portion 38 are shown in FIGS.
As shown in FIG. 15 and FIG.

As shown in FIG. 14, the detachable portion 38 has a pair of container pressing plates 43 on both left and right sides of its lower portion, and a holding body 44 above both container pressing plates 43. Both pressing plates 43 stabilize the container 7 on the transfer device 37, and can be reciprocated toward the center by a cylinder (not shown). As shown on one side of FIG.
When the holding plate 43 moves forward, it rests on the shoulder of the container 7 body, and the holding plates 43 on both sides press the container 7,
The container 7 is stably fixed at a predetermined position of the transfer device 37.

Both clamping members 44 are curved in a circular shape as shown in FIG. 15, and a clamping member 45 such as rubber having a high friction coefficient is provided on the clamping surface in contact with the lid member 10. It is provided on a support member 47 that is vertically provided on the lower surface of a support plate 46 that is rotatable in the horizontal direction. The holding body 44 is normally located under the support member 47, but as shown in FIG. 15, the base portion of the holding body 44 is fitted on the inner side surface of the support member 47 and can be slid up and down along the support member 47. Has become. Both support members 47 themselves are slidable toward the center of the support plate 46 by a cylinder 48 provided on the lower surface of the support plate 46. The pressure contact member 45 may have an uneven surface on its surface.

The entire lid attaching / detaching portion 38 can be moved up and down by the cylinder 51 shown in FIG. 13, and when the container 7 is set at a predetermined position as described above, the attaching / detaching portion 38 is lowered. When the detaching / attaching portion 38 descends and stops, the left and right holding plates 43 are at the height position of the shoulder portion of the container 7 main body, and the both holding bodies 44 are at the same height position as the lid body 10 on the side surface of the lid body 10. It is in.

When the attaching / detaching part 38 descends to a predetermined position and stops in this way, the pressing plate 43 is advanced to move the container 7
After the main body is stabilized, the holding member 44 is advanced to the container 7 side together with the support member 47 by the cylinder 48, and the pressure contact members 45 are pressed against both sides of the lid body 10 and held. Thereafter, if the support plate 46 is rotated in the screw opening direction of the lid body 10 via the chain 50 by the reversible drive motor 49, the lid body 10 is pulled up along the spiral, but the holding body 44 is held.
Since it is slidably provided on the support member 47, the holding body 44 also rises as the lid 10 rises.

When the lid 10 rises while rotating and reaches the position where it is separated from the threaded portion of the container 7 main body, the entire detachable portion 38 is raised by the cylinder 51 and stopped at a predetermined height position. As a result, the holding plate 43 is separated from the main body of the container 7 to open the container 7, and the holding body 44 holds the lid 10 in the hollow portion. The support plate 46 is adapted to rotate independently in the detachable portion 38 about the bearing 46a, and therefore the detachable portion 38 itself and the holding plate 43 do not rotate.

In FIG. 14, reference numeral 52 denotes a vacuum pad, which is attached to a frame body connected to the lower center of the support plate 46 so as to be vertically movable. In a normal state, the spring 52a has an elastic action so as to have a downward habit. Has been granted. Lid 10
In order to remove the vacuum pad 52, the vacuum pad 52 comes into contact with the upper surface of the lid body 10 at this time. At this time, a vacuum pump (not shown) directly connected to the vacuum pad 52 is operated, and the vacuum pad 52 is attracted by a suction force. If is attached to the lid 10, the existence of the lid 10 is confirmed. If the vacuum force does not work, it means that the lid body 10 does not exist at a predetermined position or the lid body 10 does not exist in the main body of the container 7, and at this time, the lid body attaching / detaching portion 38 should not operate. You can

The lid 10 is provided on both sides of the vacuum pad 52.
A pressing member 53 is provided. The pair of pressing members 53 themselves are also attached to the frame body so as to be movable up and down, and in the same state as the vacuum pad 52, the elastic action of the spring 53a imparts downward habit. If the pressing member 53 is pressed against the upper surface of the lid body 10 by the spring 53a when the removal work of the lid body 10 is started, the lid body 10 can rotate in a horizontal state without tilting.

Then, as described above, when the lid 10 is separated from the container 7 and the entire attaching / detaching portion 38 rises, the spring 52a is released.
And 53a act to push down the lid body 10 by the elastic elasticity thereof, so that both nipping bodies 44 holding the lid body 10 are held.
Also moves to the lower end of the support member 47 to hold the lid 10. Although the lid 10 is removed after weighing in the above description, the lid 10 may be removed first and then weighing may be performed.

The container 7 with the lid 10 removed is moved forward by the transport device 37 and stopped at the position where it reaches the reversing portion 39. In this case as well, similarly to the above, the stopper may be used at the same time when the transport device 37 is stopped. In the reversing section 39, the openings are reversed toward the hopper 9 side centering on both sides of the container 7, and the powder is put into the hopper 9. As the reversing mechanism of the container 7, for example, Japanese Patent Application No. 5-48692.
It is possible to use a turning mechanism provided as a Japanese Patent Laid-Open No. 6-241871.

Further, it is also possible to use the reversing unit 39 shown in FIGS. 16 and 17. Inversion unit 3 shown in FIG.
A pair of left and right pressing members 54 can be pressed against both side surfaces of the container 7 and can be inverted in the direction of the hopper 9 while holding both sides of the container 7 therebetween.

For this purpose, the drive shaft 55 of the pressure contact member 54 and the cylinder 56 are connected via a link ball 57, and both drive shafts 55 are synchronized via a rotary shaft 58 provided above the reversing portion 39. It is rotatably connected. Each of the drive shaft 55 and the rotary shaft 58 has a sprocket 5
9 and 60 are connected by a chain 61, and another sprocket 62 provided on the drive shaft 55 on one side is connected by a chain to a drive sprocket of a motor (not shown).

The container 7 from which the lid 10 is removed is the transport device 3
When it is transferred to the reversing section 39 by 7 and stopped, the cylinder 56 is operated and the pressure contact member 54 is moved forward to move the pressure contact member 5
4 is brought into contact with the side surface of the container 7. The contact surface of the pressure contact member 54 with the container 7 is provided with a pressure contact material such as rubber having a high friction coefficient.

After the container 7 is gripped by the two pressure contact members 54, the motor is driven to rotate the drive shaft 55 on one side, and the rotational force is transmitted to the other drive shaft 55 via the rotary shaft 58.
Both drive shafts 55 rotate in synchronization. The rotation direction is set so that the opening of the container 7 faces the hopper 9 side (left side in FIG. 12), whereby the powder contained in the container 7 is put into the hopper 9. It will be. When all the powders have been charged, the container 7 is reversed and returned to a predetermined state. In this state, the pressure contact member 54 is pulled back to a predetermined position by the cylinder 56, and the container 7 is opened.

The opened container 7 is moved in the opposite direction by the transfer device 37 and stops below the lid attaching / detaching portion 38. As described above, the holding body 44 waits upward while holding the lid body 10 therebetween, and the empty container 7A stops below the lid body 10 (the empty container 7A is stopped in the same manner as described above). Then, the detachable portion 38 is lowered by the cylinder 51 and stopped at a predetermined height position. Presser plate 4
3 is placed on the shoulder of the container 7 body to hold down the container 7,
Since the lid body 10 is in a position where it comes into contact with the lid body 10 by the springs 52a and 53a, if the support plate 46 is rotated in the opposite direction to the above, that is, in the screwing direction of the lid body 10 by the operation of the drive motor 49, The lid 10 descends along the spiral of the container 10 and is fastened and attached to the container 7.

The containers 7 may have the same structure but different weights. Therefore, the empty container 7A after the powder is charged is weighed again by the weighing device 40, and the measured value of the entire container 7 when the powder is stored and the measured value of the empty container 7A are calculated, and the hopper 9
Measure the amount of powder supplied to. In this case, the measurement is carried out under the same conditions as the initial measurement. That is, when the powder container 7 with the lid 10 removed is weighed, the empty container 7A is also in the state with the lid 10 removed, and when the powder container 7 with the lid 10 is weighed. It is necessary that the empty container 7A also be provided with the lid 10.

An empty container 7A with the lid 10 finally attached
Is further returned to a predetermined position by the transport device 37, grasped by the hand section 16 of the transfer section 6, and carried to the empty container setting section 14. The work of gripping the container 7 by the hand portion 16 is the same as the above case. After carrying the empty container 7A to the installation unit 14, the transfer unit 6 moves to a predetermined container 7, and the powder processing unit 8
The powder in the container 7 is fed to the hopper 9 by the same operation.

By repeating the above operation, a plurality of kinds of powders having different content components are supplied to the hopper 9. Crane 1 moves and first container 7
Since a series of operations for grasping the powder and putting the powder in the container 7 into the hopper 9 in the powder processing unit 8 are all managed and controlled by the computer, they can be automatically processed. Since the direction of the container 7 is always constant on the powder processing unit 8, when the empty container 7A after the powder is fed in is returned below the lid attaching / detaching unit 38, the lid 1 descends while rotating.
0 is screwed into the container 7 as it is, and the transfer device 37
Even when returning to the predetermined position, the gripping operation by the hand unit 16 can be reliably performed.

As shown in FIGS. 1 and 13, if a temporary storage space 63 for the container 7 containing the powder is formed on the side of the powder processing unit 8, the container 7 containing the powder in advance can be provided. It can be installed in this temporary storage space 63. Therefore, when the powder processing operation is performed in the powder processing unit 8, the transfer unit 6 installs a new container 7 in the temporary storage space 63, and the transfer unit 6 transfers the empty container 7A into which the powder has been charged. If the container 7 on the temporary storage space 63 is sent to the transfer device 37 by the cylinder 64 during the transportation to the installation location 14, the powder treatment can be continuously performed without waiting for the passage of time. Further, after the empty container 7A is carried to a predetermined place, the transfer unit 6 moves the next container 7 to the temporary storage space 6
Just bring it to 3.

The hands 23 and 24 of the hand section 16 described above.
Corresponds to a rectangular container 7 having a concave portion 11 that can be lifted on the side surface. The hands 23 and 24 cannot be used in the case of a circular container such as a container having no such recess 11 or a drum can. In such a case, the pads shown in FIGS. 18 and 19 can be used as an alternative to the hands 23 and 24.

The pad 64 shown in FIG. 18 is for vacuum suction, and a large number of small holes 65 are formed in the suction surface of the pad 64, and each small hole 65 is provided with one air suction pipe 66. It is connected to a vacuum pump (not shown).
