The first checking part 130 scans (scan) the unique identifier to confirm chemical information, and the control part can confirm whether or not the chemical information is identical to the chemical required by the chemical supply device 5 from the confirmed chemical information of the chemical container 2 and the tray 3. In this case, the first inspection unit 130 may be configured to scan a unique identifier attached to the chemical container 2.
In addition, the at least one transport route 100, 200, 300, 400 may further include a second transport route 200, and the second transport route 200 may be disposed adjacent to the first transport route 100 in parallel.
A carry-out section 210, a second alignment section 220, and a second inspection section 230 are arranged in this order on the second conveyance path 200. A plurality of transport members are arranged along the transport direction in the carrying-out section 210, the second aligning section 220, and the second inspecting section 230 to transport the chemical container 2. In this case, the carrying member is rotatably driven, and the chemical container 2 can be carried bidirectionally along the second carrying route 200.
The carrying-out unit 210 is disposed to carry out the chemical container 2 used by the chemical supply device 5 to the outside after being carried through the second carrying line 200. The carry-out part 210 may be disposed adjacent to a side of the launch part 110.
When the chemical container 2 is transported to the carrying-out section 210, the tray 3 on which the chemical container 2 is loaded is lifted by the forklift 4 behind the carrying-out section 210 and carried out to the outside.
On the other hand, when a problem such as a failure occurs in the dosing unit 110 or the first transport path 100, the chemical container 2 cannot be dosed by the dosing unit 110. In this case, the chemical container 2 is loaded by the carrying-out unit 210, and the carrying-out unit 210 can be used as a loading unit. On the contrary, when a problem such as a failure occurs in the carrying-out unit 210 or the second transport path 200, the chemical container 2 may be carried out by the loading unit 110.
The second alignment portion 220 performs the same function as the first alignment portion 120. Accordingly, in order to align the chemical container 2 loaded by the carry-out section 210 in a skewed state when the chemical container is carried, the second aligning section 220 may be configured to align the chemical container 2 toward a center portion of the second carrying line 200. In addition, in the case where the used chemical container 2 is transported by the carrying-out part 210, the chemical container may be transported after alignment is performed by the second aligning part 220. The second alignment portion 220 may be disposed adjacent to a side portion of the first alignment portion 120.
The second inspection unit 230 may be configured to inspect chemical information of the chemical container 2 when the chemical container 2 is loaded by the unloading unit 210, and may have the same configuration as the first inspection unit 130.
A plurality of connection portions 140, 150, 160, 240, 250, 260 may be provided on the first and second transportation routes 100 and 200 to connect the first and second transportation routes 100 and 200.
The plurality of connection parts 140, 150, 160, 240, 250, 260 may include: first connection parts 140 and 240 connecting the first inspection part 130 and the second inspection part 230; second connecting portions 150 and 250 arranged at positions corresponding to a third conveying path 300 to be described later; the third connecting portions 160 and 260 are disposed at the end portions of the first and second conveyance paths 100 and 200, which are positions corresponding to a fourth conveyance path 400 described later.
The first connection portions 140, 240, the second connection portions 150, 250, and the third connection portions 160, 260 may be respectively configured by the first connection portion 140, the second connection portion 150, and the third connection portion 160 disposed on the first conveying path 100, and the first connection portion 240, the second connection portion 250, and the third connection portion 260 disposed on the second conveying path 200.
A plurality of transport members such as rollers are disposed at the first connection portion 140 (first transport path connection portion) of the first transport path 100 and the first connection portion 240 (second transport path connection portion) of the second transport path 200 along a direction perpendicular to the transport direction of the first transport path 100 and the second transport path 200, and when the transport members are driven, the chemical container 2 that has been placed on the transport member of the first transport path connection portion 140 is transported in the direction of the second transport path 200 and can be placed on the second transport path connection portion 240.
As an example, if the first inspection unit 130 determines that the chemical container 2 transferred from the dispenser 110 is not the chemical required by the chemical supply device 5 and determines that the chemical container is erroneously dispensed, the transfer direction of the chemical container 2 is switched, the chemical container 2 of the first transfer line connecting unit 140 is transferred to the second transfer line connecting unit 240, and then the chemical container can be transferred by the transfer unit 210. In addition, the transport can be performed in the opposite direction.
The second connection portions 150 and 250 and the third connection portions 160 and 260 may be configured in the same manner as the first connection portions 140 and 240, and the chemical container 2 may be transported in the second transport path 200 direction in the first transport path 100 or the chemical container 2 may be transported in the first transport path 100 direction in the second transport path 200.
When the chemical container 2 is dropped into the second carrying line 200 by the carry-out unit 210, the chemical container 2 is inspected by the second inspection unit 230, then passes through the first carrying line 100 in the width direction by the second connection units 150 and 250, and then is carried to the third carrying line 300.
The third carrying route 300 is vertically connected to the first carrying route 100 and to the second connecting portions 150 and 250.
The fourth carrying path 400 is disposed adjacent to the third carrying path 300 in parallel at the end portion of the first carrying path 100, is perpendicularly connected to the first carrying path 100, and is connected to the third connecting portions 160 and 260.
In the third and fourth carrying lines 300 and 400, a carrying member may be disposed from a start point to an end point to carry the chemical container 2 and the tray 3. Foreign matter adheres to the outside of the chemical container 2 and the tray 3, and is carried along a carrying route or interferes with the chemical supply device 5 when removing or remounting a lid of the chemical container to cause malfunction, and may affect the purity of the chemical. Accordingly, the third carrying route 300 may have an air shower portion 310 for removing foreign materials attached to the chemical container 2 and the tray 3.
When the chemical container 2 enters the Air shower portion 310 through the second connection portion 150 of the first carrying path 100, air (Air) is injected into the Air shower portion 310 for a predetermined time, so that foreign matters attached to the chemical container 2 and the tray 3 can be removed.
At least one buffer portion 301, 302, 303, 304 is disposed on the transfer path 100, 200, 300, 400, and the at least one buffer portion 301, 302, 303, 304 allows the chemical container 2 passing through the first inspection portion 130 to temporarily wait before being supplied to the chemical supply device 5.
In the present embodiment, the buffer portions 301, 302, 303, and 304 are disposed in the third route 300 and the fourth route 400.
The buffer portions 301, 302, 303, and 304 include a first buffer portion 301 and a second buffer portion 302 arranged in the third path 300, and a third buffer portion 303 and a fourth buffer portion 304 arranged in the fourth path 400.
The first buffer portion 301 and the fourth buffer portion 304 are disposed adjacent to each other at positions facing each other, and the second buffer portion 302 and the third buffer portion 303 are disposed adjacent to each other at positions facing each other.
A chemical container feed port 331 is provided between the first buffer 301 and the second buffer 302, and allows the chemical container 2 to be fed to the chemical supply device 5. The chemical container input port 331 is a position where the chemical container 2 is input, and a fifth connection portion 330, which will be described later, can perform the function of the chemical container input port 331.
In addition, there may be a chemical container carrying-out port 341 for carrying out the chemical container 2 carried out from the chemical supply device 5 to the third carrying route 300. The chemical container outlet 341 is a position where the chemical container 2 is carried out, and a sixth connection part 340, which will be described later, may perform a function of the chemical container outlet 341.
At least two connecting portions 320, 420, 330, 430, 340, 440 are provided between the third and fourth carrying routes 300, 400 to carry the chemical container 2 from the third carrying route 300 to the fourth carrying route 400 or to carry the chemical container 2 from the fourth carrying route 400 to the third carrying route 300.
The at least two connection parts 320, 420, 330, 430, 340, 440 include: a fourth connecting portion 320, 420 connecting between the third carrying route 300 and a side close to the first carrying route 100 in the fourth carrying route 400; and sixth connecting portions 340 and 440 connecting the third carrying route 300 and a terminal portion of the fourth carrying route 400 distant from the first carrying route 100.
In this case, the chemical container 2 used in the chemical supply device 5 is guided out from the chemical supply device 5 and then is transported to the sixth connection portion 340 of the third transport path 300 by a transport vehicle 600 described later, and the chemical container 2 of the sixth connection portion 340 is transported to the sixth connection portion 440 of the fourth transport path 400. Thus, the sixth connecting portions 340 and 440 serve to move the chemical container 2 in the direction of the fourth carrying route 400 in the third carrying route 300.
On the other hand, the fourth connecting portions 320 and 420 are used for supplying the chemical container 2 temporarily waiting at the buffer portions 303 and 304 disposed on the fourth carrying route 400 to the chemical supply device 5 through the third carrying route 300. That is, the chemical container 2 in the third buffer 303 or the fourth buffer 304 is transported to the third transport path 300 through the fourth connection 320 or 420 in the fourth transport path 400, then transported to the chemical container input port 331 along the third transport path 300, and then input to the chemical supply device 5.
The sixth connecting portions 340 and 440 are used to move the chemical container 2 used in the chemical supplying apparatus 5 in the direction of the fourth carrying route 400 in the third carrying route 300. That is, the chemical container 2 in the interior of the chemical supply device 5 is transported to the sixth connection portion 340 of the third transport route 300 and then to the sixth connection portion 440 of the fourth transport route 400. The chemical container 2 transferred to the sixth connecting portion 440 is transferred along the fourth transfer path 400, the third connecting portions 160 and 260, and the second transfer path 200 in this order, and then is carried out by the carrying-out portion 210.
Fifth connection parts 330 and 430 may be disposed between the fourth connection parts 320 and 420 and the sixth connection parts 340 and 440. In the case where the sixth connection portions 340 and 440 fail to transport the chemical container 2 of the chemical supply device 5 through the sixth connection portions 340 and 440 due to a failure or the like, the chemical container 2 used up in the chemical supply device 5 can be transported to the fourth transport route 400 through the fifth connection portions 330 and 430.
That is, in the case where the delivery route at the delivery position is broken, the chemical container 2 can be delivered from the chemical supply device 5 through the delivery route at the dispensing position. In contrast, in the case where the delivery route located at the delivery position is broken, the chemical container 2 may be delivered to the chemical supply device 5 through the delivery route located at the delivery position.
The fifth connection portion 330 disposed on the third carrying route 300 may function as the chemical container input port 331 for inputting the chemical container 2 to the chemical supply device 5.
A first driving portion for conveying the chemical container 2 in the third conveyance route 300 direction and a second driving portion for conveying in the chemical supply device 5 direction, which is the direction perpendicular to the third conveyance route 300, may be arranged at the fifth connection portion 330.
The first driving portion may be constituted by the conveying member such as the roller as described above. The second driving unit may be movable in the vertical direction between the transport members, and when the chemical container 2 is positioned on the fifth connecting portion 330, the second driving unit may be driven to lift the chemical container 2 from the transport member of the first driving unit to the upper side and then may be transported in the direction of the chemical supply device 5.
On the other hand, the first to third connecting portions 140, 240, 150, 250, 160, 260 as described above are provided with a carrying member such as a roller to carry the chemical container 2 in both directions of the first carrying route 100 in the direction of the second carrying route 200 and in the opposite direction thereto. In addition, the fourth to sixth connecting portions 320, 420, 330, 430, 340, 440 also have a carrying member such as a roller to carry the chemical container 2 in both directions in the direction of the fourth carrying route 400 and in the opposite direction to the fourth carrying route 300.
As described above, if the plurality of buffer portions 301, 302, 303, 304 are disposed in the third and fourth carrying lines 300, 400, the number of chemical containers 2 to be put into the chemical supply device 5 can be secured in a large amount, and thus the demand for the chemical required by the chemical supply device 5 can be satisfied immediately.
In addition, the plurality of connection parts 320, 420, 330, 430, 340, 440 are disposed between the third transfer path 300 and the fourth transfer path 400, and the operation of putting the chemical container 2 in the chemical supplying apparatus 5 or carrying out the chemical container 2 from the chemical supplying apparatus 5 can be simultaneously performed, so that the process time can be shortened.
Further, the chemical container 2 is temporarily placed on the transportation route 300 or 400, and can be continuously transported without arranging a separate waiting place.
Further, the carrying paths 100, 200, 300, 400 of the chemical container 2 are formed at right angles and the carrying directions can be switched, so that the area occupied by the automatic chemical container carrying apparatus 1 and the apparatus size can be reduced.
On the other hand, in the case where the chemical container 2 is transported along the first to fourth transportation routes 100, 200, 300, 400, the position of the chemical container 2 can be confirmed in real time by a sensor (not shown) disposed on the transportation route. That is, when the first inspection unit 130 confirms the chemical information of one chemical container 2, the chemical container 2 whose real-time position has been confirmed is sensed by the sensor disposed on the transport path, and thus the chemical information of the chemical container 2 temporarily waiting in the buffer units 301, 302, 303, and 304 can be confirmed. Therefore, in order to transport the chemical container 2 required by the chemical supply device 5, the chemical information of the chemical container 2 temporarily waiting in the buffer units 301, 302, 303, and 304 is checked, and the checked chemical container 2 can be put into the chemical supply device 5.
The chemical container 2 is thrown into the chemical supply device 5 by an unmanned transport vehicle 600 or the used cavitation chemical container 2 can be transported from the chemical supply device 5. The driving control of the transport vehicle 600 may be realized by a control unit.
For this purpose, a transport rail 500 may be disposed between the chemical supply device 5 and the third transport route 300, and the transport vehicle 600 may reciprocate.

Fig. 8 is a diagram showing a case where the transport cart 600 and the chemical supply device 5 are plural.
When a plurality of the transport vehicles 600 are arranged, they can be used for loading and unloading separately. That is, the plurality of transport vehicles 600 may be configured by a first transport vehicle 600-1 and a second transport vehicle 600-2, the first transport vehicle 600-1 being configured to deliver the chemical container 2 to the chemical supply device 5, and the second transport vehicle 600-2 being configured to deliver the chemical container 2 from the chemical supply device 5 to the delivery route. For this, the first cart 600-1 may wait at a position close to the chemical container input port 331, and the second cart 600-2 may wait at a position close to the chemical container output port 341.
In addition, the transport vehicle 600 may be provided with a plurality of transport vehicles for separately supplying or transporting different chemicals to or from the chemical supply device 5. That is, the plurality of carts 600 may be configured by a first cart 600-1 for putting a first chemical container storing a first chemical into the chemical supply apparatus 5 or carrying out from the chemical supply apparatus 5, and a second cart 600-2 for putting a second chemical container storing a second chemical into the chemical supply apparatus 5 or carrying out from the chemical supply apparatus 5.
In this case, the chemical supply device 5 may be constituted by a first chemical supply device 5-1 and a second chemical supply device 5-2, the first chemical supply device 5-1 dosing a first chemical container storing a first chemical, and the second chemical supply device 5-2 dosing a second chemical container storing a second chemical.
Of course, other chemical supply means may be provided for supplying also other kinds of chemicals than the first chemical and the second chemical.
The first cart 600-1 may be configured to allow the first chemical container to be introduced into the first chemical supply device 5-1, and the second cart 600-2 may be configured to allow the second chemical container to be introduced into the second chemical supply device 5-2.

In the case of placing a second chemical container in the second chemical supply device 5-2, a place of placement is between the second chemical supply device 5-2 and the third transport route 300.
On the other hand, another embodiment of the automatic chemical container conveying apparatus of the present invention may be configured as follows: when one of the 2 transport vehicles 600-1 and 600-2 malfunctions, the other transport vehicle is used to place a plurality of chemical containers into a plurality of chemical supply devices and to transport the plurality of chemical containers out of the plurality of chemical supply devices.
That is, the chemical agent container is constituted by a plurality of chemical agent containers that store a plurality of chemical agents, respectively; the chemical supply device 5 is constituted by a plurality of chemical supply devices 5-1, 5-2 to which the plurality of chemical containers are respectively put. In the case where the plurality of transport vehicles 600 are provided, one transport vehicle 600-1 of the plurality of transport vehicles 600-1 and 600-2 may be configured to place the plurality of chemical containers in the plurality of chemical supply devices 5-1 and 5-2, respectively, and then to carry out the plurality of chemical containers from the plurality of chemical supply devices 5-1 and 5-2, respectively.
In another embodiment, when a plurality of transport carts 600 are provided, the chemical container may be loaded into the chemical supply device 5 by at least one transport cart, and the chemical container may be transported out of the chemical supply device 5 by another transport cart. In this case, the chemical container and the chemical supply device 5 may be constituted in plural numbers, respectively.
This will be explained in more detail. The chemical supply means 5 is constituted by a first chemical supply means 5-1 for supplying a first chemical and a second chemical supply means 5-2 for supplying a second chemical. In addition, the transport cart 600 is composed of a first transport cart 600-1 and a second transport cart 600-2. In addition, the chemical container is constituted by a first chemical container storing the first chemical and a second chemical container storing the second chemical. In this case, the first carriage 600-1 is used for feeding the first chemical container to the first chemical supply device 5-1 and the second chemical container to the second chemical supply device 5-2. The second cart 600-2 carries out the first chemical container from the first chemical supply device 5-1 and carries out the second chemical container from the second chemical supply device 5-2 as carrying-out.
Referring to fig. 9, a path for carrying the chemical container 2 and the tray 3 when the chemical container is dropped by the dropping unit 110 will be described.
When the chemical container 2 is placed on the placing portion 110 by the forklift 4, the chemical container 2 is transported along the first transport path 100 by the driving of the transport means.
The chemical container 2 is aligned by the first alignment portion 120. Thereafter, the first inspection unit 130 inspects the chemical information, the position abnormality, and the like, and then, if the inspection result indicates that there is no abnormality, the chemical container is transported along the first transport route 100, if an abnormality is found, an Alarm (Alarm) is generated to allow the worker to directly confirm again, and if the confirmation result determines to collect the chemical container 2 and the tray 3, the chemical container is transported from the first transport route connecting unit 140 to the second transport route connecting unit 240, transported along the second transport route 200 to the delivery unit 210, and then collected by the forklift 4.
If the worker confirms that the first inspection unit 130 takes measures after finding the abnormal portion, the worker performs the re-inspection by the first inspection unit 130, and if there is no abnormality, the worker carries the work along the first carrying route 100.
The chemical container 2 confirmed by the first inspection part 130 as having no abnormality is transferred to the air shower part 310 by switching the transfer direction by 90 degrees at the second connection part 150. The Air shower portion 310 sprays Air (Air) for a predetermined time to remove foreign matters attached to the outside of the chemical container 2 and the tray 3.
