Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a powder or granular material such as a medicine, etc., in which material is automatically taken out from a storage container containing powder or granular material and distributed to a storage tank. related to transportation systems.

[Conventional technology] Conventionally, in the pharmaceutical industry, etc., materials in a quantity corresponding to a desired blending ratio are transferred into a portable closed container with a lid from a fixed source tank that stores a large amount of multiple types of powder and granules. After the container is placed in a tumbler (rotating mixing tank), it is mixed uniformly, and the mixed materials are once again transferred to the container and placed in a designated position. Generally, a compounding and mixing transportation system is employed in which the ingredients are put into a hopper of a distribution transportation device and then supplied to a desired tablet making machine, packaging machine, or the like.

However, in such conventional mixed mixing transportation systems, when the materials stored in a closed container with a lid are transferred to a tumbler or the like and the mixed materials are transferred back to the container, the materials are unnecessarily exposed to air. There were problems such as touching and scattering.

Therefore, in order to solve these conventional problems, the present applicant proposed a transportation device for fluids such as powder and granules in Japanese Patent Publication No. 4309/1983.

Figure 9 shows the structure of the device according to this proposal.
A discharge section 100a is provided at the top end of a device section consisting of a storage container A' having an opening at the top that accommodates a fluid such as powder, a transportation device B', and an inversion device CI. The conical part 100 is formed separately from the conical part 100,
It has a conveying section 101 that can support the conical section 1000 in an upside-down state with the top end facing down, and the reversing device C' includes a rotating mechanism 103 supported by a frame 102 at an appropriate position above, and a rotating mechanism 103 that is A container holding mechanism 104 fixed to the output shaft 103 & for holding the storage container A'
and an elevating frame 105 that can lift the storage container A' to the height of the container holding mechanism 104.

In such a device, the nut (not shown) of a tightening tool tightening the lid placed on the storage container A' is loosened, the lid is removed, and the top and bottom of the conical portion 100 of the transport device B' are tightened instead. Reversely, put the opening edge 10B over the open opening edge of the container A', tighten the tightening tool 104 which is the container holding mechanism again with the bolt 106 and nut 107 to seal the container 2, and then close the container. Turn the top and bottom of A' upside down as shown in the figure, and pour the material in the conical part 10 into the same container.
At the same time, a transport pipe (not shown) is connected to the connection part 109 connected to the discharge part 100a at the lower end of the conical part 100, and the pressurized air supply port of the control box is connected to the discharge part 100a.
a and the connecting part 109 with piping, and then pressurized air from a pressure supply device sent through the control box is supplied from the gas supply port provided in the discharge part 100a and the connecting part 109 to move the material to the desired location. It is designed to be pumped to
Ru.

Therefore, since the storage container into which materials are transferred from the large original tank itself becomes a material supply tank, the same container can be used consistently when transporting materials, preventing materials from scattering, and avoiding unnecessary air contact. This enables efficient transportation work.

However, in such a device, after carrying the container onto the lifting pedestal of the reversing device and cutting it, and replacing the lid and conical part, the lifting pedestal is raised to an appropriate height and then opened. The structure is such that the belt-like metal fittings of the inverting device that have been set up are manually closed, and the outer periphery of the storage container is held in the container holding mechanism by operating the tightening device. It has become difficult to adapt to today's production systems.

The present invention automatically transports the powder and granules stored in a storage container with a lid removed to a reversing loading device without exposing it to air carelessly, and connecting the reversing loading device to a storage tank. The object of the present invention is to provide a transportation system for powder and granular materials that can be distributed and supplied to an automatic pipe attachment/detachment device and that is easy to operate.

[Means for Solving the Problems] The system of the present invention proposed to achieve the above object has the following configuration.

That is, this system includes a reversing loading device that takes in and out a storage container containing powder and granular material with the lid removed, and sealingly connects the storage container to the discharge portion thereof, and a storage container set in the reversing loading device. In order to receive the material contained therein and send it to the storage tank, it is constructed by combining an automatic piping detachment device which is detachably connected to the discharge part of the reversing and feeding device.

The reversing and loading device has a main body that has a drive source and can be rotated in the horizontal direction, and a front frame that is attached to this main body via a drive shaft so that it can be vertically reversible. On the upper side of the frame plate, there is provided a discharge part having an opening edge and pulp that hermetically connects the frontage of the storage container with the lid removed, and on the lower side of the front frame, the storage container with the lid removed is provided. A loading table is provided with a roller conveyor for loading and unloading.

On the other hand, the automatic pipe attachment/detachment device has a material receiver fixed at a predetermined position in a turning area centered on the main body of the front frame plate of the reversing/feeding device, and this material receiver has an inlet. The mouth is connected to the storage tank via a transport pipe, and is configured to move up and down in order to be removably connected to the discharge part of the front frame plate of the inversion device.

In such a system of the present invention, after the storage container from which the lid has been removed is hermetically connected to the opening edge of the discharge section provided in the reversal input Ha, the pulp of the discharge section is opened and the material stored in the storage container is released. The simplest configuration is to supply the material to the mouth of the automatic piping membrane @ device by dropping the material under its own weight. A configuration may also be adopted in which gas is sent into the container and the material is exhausted by force.

[Operation] According to the system of the present invention, the storage container from which the top lid has been removed is carried into the reversing device, and the front edge of the discharge portion is crimped to the opening edge of the storage container to form a sealing connection, and then the main body portion is inserted into the material. The material receiver of the automatic pipe attachment/detachment device that is to be dispensed is rotated to the position where the mouth is located, and the material receiver is then raised with its inlet and connected to the above-mentioned discharge section to release the material contained in the container. can be supplied into the storage tank under its own weight.

Therefore, the series of operations after removing the lid of the storage container containing the powdered material and supplying it to the storage tank can be completely automated, and can be carried out without inadvertently exposing the material to the air. .

Moreover, in the system described in claim 2, the material in the storage container is discharged and distributed and supplied by pneumatic transport.

Furthermore, in the system described in claim 3, the storage container can be hermetically connected to the discharge portion easily by the cross-shaped lifting auxiliary frame plate.

, 5a are raised and connected to the discharge port 21b of the discharge section 21 of the reversing/feeding device A.

After the material receiving port 5a (5'a) is hermetically connected to the discharge part 21 in this way, the pulp 27 of the discharge part 21 is opened and the material accommodated in the container 3 is discharged. The receiver is put into the inlet 5a (5'a) and supplied into a storage tank (not shown) via the transport pipe 5.

Next, details of each device constituting the system of the present invention will be explained.

First, to explain the structure of the reversing loading device ff1l, this device A has a structure in which casters Ib are provided below a base 1a on which a main body part 1 is rotatably mounted, so that it can be transported and moved on the floor. Holding hands 23, 23 which expand as the body moves up and down are attached to the main body 1 so as to be reversible up and down by drive shafts 2a of the front frame plate 2 provided on both sides.

The main body part l of this reversing feeding device A is driven by a motor (not shown) provided in its base part la, and the material receptacle of the automatic pipe removal device B, which will be described later, is provided with an inlet 5a (5'a). The front frame plate 2 is also configured to be able to rotate the drive shaft 2a in the forward and reverse directions using a motor provided inside the main body 1 via a transmission mechanism. (In Figure 1, the front frame plate is inverted.)

Further, a support stand 26 is provided on the upper side of the front frame plate 2, and a discharge portion 21 is provided in the center thereof.

Here, the discharge part 21 is opened in order to be hermetically coupled to the opening 3& of the storage container 3 from which the lid 3b has been removed. t21
A sealing material is interposed in a, and a ball pulp 27 is provided at the lower end of the sealing material (see FIG. 6).

On the other hand, as shown in FIG. 4, the mounting table 22 attached to the lower side of the front frame plate 2 is provided with a plurality of large and small roller conveyors 28, 28' for conveying the storage containers 3. In the gaps between these roller conveyors 28, 28', the rotating shafts 28a of each roller 28, 28' are fitted into slits 29b formed below the frame member 29a, so that they can move up and down. An elevating auxiliary frame plate 29 in the form of a parallel girder is provided, and an air knocker 22d that applies vibration from the bottom of the storage container 3 is further provided on the bottom plate of the mounting table 22.
is attached.

As shown in FIG. 4, the roller conveyor 28, 28' has pulleys (not shown) attached to both ends of the rotating shaft 28a.
A belt (not shown) is passed over the belt, and the rotational output of a motor 22b provided under the loading table 22 is transmitted to the booth to rotate it. The auxiliary frame board 29 is fixed to the tip of a support frame (not shown) to which drive shafts (not shown) of a pair of left and right hydraulic cylinders provided on both sides of the front frame board 2 are connected. When the drive shaft of the provided hydraulic cylinder is operated up and down, the support frame moves up and down, and the auxiliary frame plate 29 fixed to the tip of the support frame comes out and disappears from the gap between the roller conveyors 28 and 28', and the auxiliary frame plate 29 When the container 3 is raised, the opening 3a of the container 3 from which the lid 3b has been removed is pressed against the opening edge 21a of the discharge portion 21 and is hermetically coupled.

Note that 24 is a position detection sensor for detecting whether the position of the storage container 3 transferred onto the mounting table 22 is appropriate, and 25 is a sensor for detecting the state of the storage container 3 being crimped onto the discharge part 21. This is a crimping detection sensor installed in the

Further, an auxiliary frame 23a with holding hands 23, 23 attached to both sides is installed horizontally at an intermediate position between the upper and lower sides of the front frame plate 2.
When the above-described hydraulic cylinders provided on both sides of the frame are driven, the frame expands as the auxiliary frame plate 29 moves in and out.

FIG. 4 shows an example of the operating mechanism of the holding hand in detail.

In this figure, reference numeral 23a denotes an auxiliary frame with a U-shaped cross section installed horizontally at an intermediate position above and below the front frame plate 2. This auxiliary frame 23a can be moved up and down by the drive of hydraulic cylinders provided on both sides of the front frame plate 2. It is designed to go up and down.

A box body 23b has a pair of arch-shaped hands 23.23 fixed to both ends of the auxiliary frame 23a to hold the storage container 3 placed on the mounting table 22 from both sides.
, 23b are pivotally connected by shafts 23c, 23C, and guide rollers 23d, 2 are provided on the opposite side of the box bodies 23b, 23b.
3dfi: Arms 23e and 23e are provided, and a pair of hands 23.23 is provided to expand the hand 23.23, which is always urged in the direction of contraction by a spring (not shown). When the auxiliary frame 23a moves up and down, the guide rollers 23d and 23d are provided with inclined portions 22e and 23d formed on the front frame plate 2 side.
22e, and as a result, when the rollers 23d, 23d are below the inclined portions 22e, 22e, the force resisting the biasing force of the spring is the largest, and the hand 23° 23 is opened and accommodated. The holding of the container 3 is facilitated, but as the rollers 23d and 23d move upward, the force against the biasing force of the subunong is loosened, and the holding hands 23, 23 are gradually closed to firmly hold the container 3. .

FIG. 5 shows a detailed view of the structure of the discharge section provided in the front frame. In this example, the discharge section 21' is formed in a conical shape, and the gas supply port 21' for introducing the transport gas into the interior thereof is shown in detail. ' It has a structure with c. In addition, 21'
d is an air knocker for discharging the material in the discharge section 21' without leaving any residue, and 27 is pulp.

In such a structure, when the transport gas is supplied from the gas supply port 21'c, the internal pressure of the storage container 3 containing the material is increased and the material can be exhausted from the discharge port 21'b.

Next, the structure of automatic pipe attachment/detachment device B will be explained.

In FIGS. 1 and 6, this automatic piping attachment/detachment device B is arranged so that its material receiving port 5 a + 5 a ′ is located on the floor 6 on which the above-mentioned reversing feeding device A is loaded. and these material receivers are 5 a + 5
a' is reversed! ! In the turning area centered on the main body part 1 of the position A, projecting openings are made at positions that are perpendicular to each other when viewed from the main body part 1 (FIG. 1).

(See Figure 3).

One of the inlets of the two material receivers is a main supply port 5a, and the other is an auxiliary supply port 5'a, and a transport pipe 5.5° is connected below these. The ends of the transport pipes 5 and 5' are merged together into one storage tank (
(not shown).

Here, the main supply port 5a is used when the entire amount of material in the storage container 3 can be stored in the storage tank, and the auxiliary supply port 5a is used when the storage tank is almost full and the material in the storage container 3 is used. It is used to receive a portion of the amount on a preliminary basis when the entire amount cannot be supplied. The selection of the main supply port 5a and the auxiliary supply port 5'a is performed under the control of a controller (not shown).

The material receiving port 6a, which serves as the main supply port, has an inner cylinder 50 that is raised and lowered up and down by the expansion and contraction movements of the rods 41a and 41a of two lifting cylinders 41 and 41.
A cover plate 43 constituting a shutter means is provided at the opening 0. As shown in FIG. 2, the inner shutter means 1150 has a disc-shaped cover plate 43 with an arm 43a attached to the center, and a link 43b attached to the arm 43a is movable. The structure is such that the opening of the inner cylinder can be opened and closed by sliding the lid plate 43.

Of these, the shutter means provided in 1ff 150 is closed when the discharge port of the discharge section 21 of the above-mentioned reversing and feeding device tA is not coupled to prevent dirt and dust from entering from the outside.

A tapered cylinder 5b is connected to the lower part of the inner cylinder 50, and a transport pipe 5 in which pulp 61 is interposed is connected to the lower part of the cylinder 5b. This transport pipe 6 has a material receiving port 6a.
A supply tank 11 is provided on the lower floor surface 16 to temporarily store the supplied material. A metering supply device 14 is provided, and the structure is such that the material can be metered to a storage tank (not shown) provided ahead of the meter.

Air knockers 5c, 5c are provided at an appropriate interval in the middle of the transport pipe 5 connected to the main supply port 5a, so that the material falling in the transport pipe δ stays in the transport pipe 6. This prevents pipe clogging from occurring.

The other material receiver serving as an auxiliary supply port is also the inlet 5a, and the above-mentioned material receiver is a lifting cylinder 41' similar to the inlet 6a.
It has an inner W50'' that expands and contracts up and down, and a charge tank 16 for temporarily storing the material is provided below the crest-shaped 11I5'b provided below it.
Further below, a feeder 13 is provided on a frame 13a installed on the floor 16, and the outlet of the feeder 13 is connected to the transport pipe 5 via a branch pipe 12.

In addition, while transporting the storage container 3 containing the material, 7
This is a device that automatically removes the lid 3b, and the lid 3b is removed by suction force between a transport lane consisting of a plurality of roller conveyors 7a that are rotationally driven by a motor 7c, and a transport lane along the way. A frame 7d is provided on which the suction pad 7b is suspended so as to be vertically movable.

When the storage container 3 is conveyed on the conveyor lane 32 and the actuating pieces 8a, 8a of the passage detection sensor 8 detect the passage of the storage container, the suction pad 7 suspended and supported by the frame 7d
b descends and applies a suction force to lift the lid 3b out of the container 3 and remove it.

In this way, the container 3 with the lid 3b removed is fed into the weighing station 9, where it is stopped and the weight of the container 3 filled with material is measured.

The weighing station 9 has a roller conveyor 9a that is rotationally driven by a motor 9b similar to the lid removal station described above, and the conveyor lane is provided with a guide frame 9C that prevents the container from shifting. .

After such preliminary work is performed, the container 3 is sent to the mounting table 22 of the front frame 2 of the reversing and loading device 1iA.

Next, the control operation of the system of the present invention will be explained.

The system is controlled by a controller (not shown), which operates limit switches, sensors, etc. provided within the system, and sends signals to the controller to carry out the next process.

When the storage container 3 containing the powder or granules is transferred by a conveyor or other transfer means to the reversing feeding device 8 with the front frame plate 2 in the forward rotation position, the motor 22b is driven to rotate the front frame plate 2. The roller conveyor 2 provided on the loading table 22 rotates and carries the container @3 onto the loading table 22 (see Figure 6).

When the storage container 3 is carried to a predetermined position on the loading table 22 of the reversing/feeding device 1A, the sensor 24 detects this, the drive of the roller conveyor 28 is stopped, and then the auxiliary container stored in the gap between the roller conveyor 28 is The frame plate 29 is raised, and the opening m21a of the discharge part 21 is pressed to the upper opening 3a of the storage container 3, so that the opening m21a is hermetically connected.

This barking state is detected by the sensor 25, and when the discharge part 21 is crimped and hermetically coupled to the entrance 3a of the storage container 30, the drive shaft 2& is driven, and the front frame plate 2 is reversed and moved up and down. is the opposite (see Figure 7).

Next, the main body l has a material receiving opening 5a (or 5').
a) Turn to a certain position.

Here, the turning position of the main body l is defined by a command signal from the controller that has determined the amount of material stored in the storage tank. When the turning of the main body l is completed,
The shutter means is activated, and the material receiver in the automatic pipe attachment/detachment device B is opened with the lid 43 of the inlet 5a opened.
0 rises (see Figure 2, double-dot chain II, N).

In order to prevent the inner cylinder 111r50 from shifting, the two guide cylinders 42, 42 provided outside the inner cylinder are driven, and these guide rods 42a, 42a are moved by two arms from the support base 26. Guide holes 21d and 21 of the collar 21C are protruded and provided on the outer periphery of the discharge port 21b of the discharge portion 21.
I have d enter the reception.

The material in the storage container a is collected by connecting the inner tube to the discharge port 21b provided at the end of the discharge section 21, and then plucking the pulp 27 of the discharge section to drop the material stored in the storage container 3. When the material is discharged, the air knocker 22d is operated at the same time to prevent the material from remaining in the container a (FIG. 8 IIM).

The discharge of the material is controlled by a timer that has been set in advance for the time required for discharge. When the timer expires, the pulp 271 of the discharge section 21 is closed and the air knocker 2 is closed.
The operation of 2d is also stopped.

After that, the pulp 27 closes and the guide cylinder 42°42
After the guide rods 42a and 42j of the material receiver are lowered and the material receiving opening 5a is lowered, the shutter means is activated and the lid 43 is lowered.
When the frame plate 2 is closed and the front frame plate 2 returns to the normal rotation state, the auxiliary frame plate 29 is lowered and the crimping connection with the container 3 is released.

Next, the conveyor motor 22b is operated in reverse, and the container 3 placed on the mounting table 22 of the front frame plate 2 is carried out to the weighing station 9, and finally the conveyor motor 22b stops feeding. Weighing station 9
The total weight of the storage container 3 that was taken out was measured, and
When it is confirmed by the weighed value that the entire amount of material is empty, the material is delivered to the delivery station 31 (see FIG. 2) and ready for receiving the next container.

The above example shows the case where the entire amount of material contained in the storage container 3 is supplied from the main supply port 5a, but when the storage tank approaches fullness, the material in the storage container 3 is supplied from the auxiliary supply port 5'. It will be supplied from a.

In this case, the main body part 1 of the reversing input H position A carries the storage container 3, connects the storage container 3 to the discharge part 21 in a hermetically sealed manner, and then rotates to the position where the auxiliary supply port 5'a is located. The front frame plate 2 of A is reversed, and then the material receiving port of the auxiliary supply port 5''a is raised and hermetically connected to the opening fi21a of the discharge section 21.After that, the material is transported in the same manner as above. Supplied.

In addition, in the above explanation, the material contained in the storage container is
We have explained that when the pulp in the discharge section is opened, it falls under its own weight and is supplied.However, it is also possible to provide a gas supply port in the discharge section, supply the transport gas from there into the container, and discharge it by force. It goes without saying that this is a good thing, but in this case,
It is preferable to use a reverse input H position as shown in FIG.

[Effects of the Invention] According to the system of the present invention, when used in combination with a conveyor lane or other transfer means, the storage container with the lid removed is carried to the loading table, and the opening of the storage container is crimped to the discharge part. After the material is sealed and combined, the material receiver connected to the storage tank can transport the powdered material into the inlet without any personnel.Moreover, at this time, the material in the storage container is inadvertently exposed to air. Therefore, if it is applied to the transportation of materials such as powdered and granular chemicals, an ideal transportation system for powdered and granular materials with high production efficiency can be provided.
