Description

[Technical Field]

[0001] The present invention relates to a crane-mounted batcher plant and a method for adding cement to a crane-mounted batcher plant. [Background technology]

[0002] Conventionally, a method of manually operating a crane to replenish cement in a batcher plant has been known. Conventionally, a configuration in which a crane automatically tracks a worker is well known (Patent Document 1). Conventionally, a technology for automatically controlling a crane by recording its motion coordinates is known (Patent Document 2). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 4-361985 [Patent Document 2] Japanese Unexamined Patent Publication No. 62-4192 Summary of the Invention [Problem to be solved by the invention]

[0004] Among the above-mentioned known examples, the conventional method of replenishing cement using a crane on a batcher plant has the problem that, because the crane is manually operated, someone must always be present near the plant's inlet and the lifted load, resulting in high operating costs. Among the known examples, the one in Patent Document 1 has the problem that although the crane can automatically track the worker, it cannot automatically steer the crane itself to the loading port, resulting in low operability and workability. In other words, even though the crane can automatically track the worker, the operations of lifting, rotating, and lowering the cement ton bag are not automated, and the worker must perform these operations manually each time, which is cumbersome. Of the known examples, the one in Patent Document 2 appears to automatically operate to transport a load to its destination, but the operation of recording the operating coordinates is tedious, and there is also the problem that the crane's transport destination may shift depending on the weight (load) of the load. The present invention facilitates the cement replenishment work in a crane-mounted batcher plant. [Means for solving the problem]

(b) The worker manually engages the lifting hook 14 at a predetermined position on the cement ton bag 3, (c) Again, the automatic transport control is started by the automatic pilot remote controller 23, the cement ton bag 3 is automatically transported above the inlet 25 and automatically lowered, and the cement in the cement ton bag 3 is automatically supplied to the inlet 25, (d) When the supply is completed, the automatic transport control automatically moves the hanging hook 14 located above the inlet 25 to above the next cement ton bag 3 in the set transport setting order, lowers it to a predetermined height, and stops and terminates the automatic transport control. (e) Again, the worker manually engages the lifting hook 14, which is located at a predetermined height above the cement ton bag 3, with a predetermined part of the cement ton bag 3. (f) When automatic transport control is started again by the automatic pilot remote controller 23, the cement ton bag 3 is automatically transported above the inlet 25 and lowered, and the cement in the cement ton bag 3 is automatically supplied to the inlet 25. (g) When the supply is completed, the automatic transport control automatically moves the hanging hook 14 located above the inlet 25 to above the next cement ton bag 3 in the set transport setting order, lowers it to a predetermined height, and then stops and terminates the automatic transport control again. (h) When the automatic transport control is stopped, if the automatic operation remote control 23 is not operated, the automatic transport control will end, or the worker will manually engage the lifting hook 14 located at a predetermined height above the next cement ton bag 3 in the transport setting order at a predetermined part of the cement ton bag 3, (i) When the automatic transport control is started again by the automatic pilot remote controller 23, the cement ton bag 3 is transported above the inlet 25 and lowered, and the cement in the cement ton bag 3 is automatically supplied to the inlet 25. When the supply is completed, the automatic transport control automatically moves the hanging hook 14 located above the inlet 25 to above the next cement ton bag 3 in the set transport setting order and lowers it to a predetermined height, and the automatic transport control is stopped and terminated. (j) The automatic movement of the lifting hook 14 to the cement ton-bag 3 for which the transport sequence has been set, the manual locking operation by the worker, and the automatic transport of the cement ton-bag 3 to the supply port 25 are repeated, so the cement ton-bag 3 can be transported and supplied by automatically operating the crane 4 to the inlet 25 of the cement silo 2, reducing the time required for routine work, allowing workers to spend less time on other tasks, and also reducing costs because the work can be done by one person instead of two. . In the invention of claim 2, The transport sequence of the multiple cement ton-bags 3 is set, and automatic operation of the crane 4 is started using the automatic operation remote control 23 installed in a predetermined position. The mast 10 is rotated using the swivel mechanism 12 to rotate the swivel arm 11 around the center of the mast 10 so that the lifting hook 14 is automatically positioned above the cement ton-bag 3 in the set transport sequence. The hoist crane 13 is moved in the length direction of the swivel arm 11, and the lifting hook 14 is automatically lowered above the cement ton-bag 3 for which the transport sequence has been set, thereby ending the automatic transport control. The worker manually engages the lifting hook 14, which has stopped lowering, at a predetermined part of the cement ton-bag 3. The automatic operation of the crane 4 is then started again using the automatic operation remote control 23. The wire drum 16 automatically winds up the wire 15, and the lifting hook 14 automatically raises the cement ton-bag 3 to a predetermined height. The swivel arm 11 is then moved to the inlet 25 of the cement silo 2.

Therefore, by manually performing the most difficult tasks in the automatic operation of the crane 4, such as moving the lifting hook 14 to the cement ton bag 3 in the predetermined position and transporting the cement ton bag 3 to the inlet 25 and engaging the lifting hook 14 with the cement ton bag 3, during the automation, the automatic control of the operation of the crane 4 can be simplified, reducing work time and reducing costs by allowing only one person to perform the work instead of two. . In the third invention, A slitting cutter 50 that opens the bottom of the cement ton bag 3 is provided at the inlet 25 of the cement silo 2 so as to protrude upward, and when a worker manually engages the lifting hook 14 at a predetermined part of the cement ton bag 3 and restarts the automatic operation of the crane 4 using the automatic operation remote control 23, the cement ton bag 3 is automatically transported to above the inlet 25, the lifting hook 14 is automatically lowered toward the inlet 25, and the cement ton bag 3 is opened by the slitting cutter 50 due to its own weight, and the cement is started to be poured in, and the weight measuring unit 36 ​​constantly measures the weight of the cement ton bag 3, and when it is detected that the cement ton bag 3 has become empty based on the detection value of the weight measuring unit 36, the end of the supply work is detected. The automatic transport control automatically moves the hanging hook 14 located above the inlet 25 to above the next cement ton bag 3 in the set transport setting order, lowers it to a predetermined height, and then stops and terminates the automatic transport control again. Therefore, when the cement ton bag 3 is transported to above the inlet 25, the hanging hook 14 is lowered toward the inlet 25, and the cement ton bag 3's own weight causes it to be opened by the slitting cutter 50, allowing the automatic introduction of cement. In addition, the weight measuring unit 36 ​​constantly measures the weight of the cement ton bag 3, and when the cement ton bag 3 is empty, the refilling operation is automatically stopped based on the value detected by the weight measuring unit 36, thereby achieving automation of the cement introduction operation. . In the invention of claim 4, When the weight measuring unit 36 ​​detects the end of the release of cement from the cement ton bag 3, the lifting hook 14 can be moved above the next cement ton bag 3 in the transport order, making it easier to replenish the cement. . In the invention of claim 5, In a method of placing a plurality of cement ton bags 3 filled with cement around a batcher plant 1 in advance, lifting the plurality of cement ton bags 3 by a lifting hook 14 of a hoist crane 13 of a swivel arm 11 of a crane 4, and transporting and supplying them to an inlet 25 of a cement silo 2 of the batcher plant 1, the plurality of placed cement ton bags 3 are displayed on an operation touch panel 21 of a plant unit control panel 20 provided in the batcher plant 1, and touching the operation touch panel 21 of the displayed cement ton bags 3 to set the transport order of the plurality of cement ton bags 3, (a) Automatic transport control is started using the automatic operation remote controller 23, the lifting hook 14 is moved above the first cement ton bag 3 in the transport setting order, and the lifting hook 14 is automatically lowered to a predetermined height, and then the automatic transport control is stopped and ended.

(e) When automatic operation of the crane 4 is started again using the automatic operation remote control 23, the lifting hook 14 is automatically positioned above the cement ton-bag 3 in the set transport order, and the above steps (b) to (e) are repeated, so that the crane 4 can be automatically operated to transport and supply the cement ton-bags 3 in the set transport order to the inlet 25 of the cement silo 2 in that order, reducing the time spent on routine work and allowing the worker to focus on other tasks.In addition, the work can be done by one person instead of two, which also reduces costs. In the invention of claim 6, In a method of placing a plurality of cement ton bags 3 filled with cement around a batcher plant 1 in advance, lifting the plurality of cement ton bags 3 by a lifting hook 14 of a hoist crane 13 of a swivel arm 11 of a crane 4, and transporting and supplying them to an inlet 25 of a cement silo 2 of the batcher plant 1, the plurality of placed cement ton bags 3 are displayed on an operation touch panel 21 of a plant unit control panel 20 provided in the batcher plant 1, and touching the operation touch panel 21 of the displayed cement ton bags 3 to set the transport order of the plurality of cement ton bags 3, (a) The automatic operation of the crane 4 is started using the automatic operation remote control 23 installed in a predetermined position, the mast 10 is rotated using the swivel mechanism 12 to rotate the swivel arm 11 around the center of the mast 10 so that the lifting hook 14 is positioned above the first cement ton bag 3 in the transport setting sequence, the hoist crane 13 is moved in the length direction of the swivel arm 11, and the automatic transport control is carried out up to the lowering of the lifting hook 14 above the set cement ton bag 3, and the automatic transport control is then stopped by stopping the automatic operation of the crane 4 to end the automatic transport control. (b) With the automatic transport control terminated, the worker hooks the lifting hook 14 onto a predetermined part of the cement ton bag 3, (c) When automatic transport control of the crane 4 is started again using the automatic control remote controller 23, the wire drum 16 winds up the wire 15, the lifting hook 14 raises the cement ton bag 3 to a predetermined height, the swivel arm 11 rotates to above the inlet 25 of the cement silo 2, and once the cement ton bag 3 is transported above the inlet 25, the lifting hook 14 is lowered toward the inlet 25, and the cement ton bag 3 is opened by the slitting cutter 50 due to its own weight, and the pouring of cement begins. (d) The weight measuring unit 36 ​​constantly measures the weight of the cement ton bag 3; (e) When the discharge of the cement from the cement ton bag 3 to the inlet 25 is completed and the weight measuring unit 36 ​​detects that the cement ton bag 3 is empty, (f) automatically raising the lifting hook 14, and automatically raising, rotating and lowering the lifting hook 14 to above the next cement ton bag 3 based on a preset transport sequence; (g) When the lifting hook 14 is lowered above the cement ton bag 3, the automatic operation of the crane 4 is stopped and the automatic transport control is terminated. (h) With the automatic transport control finished, the worker removes the empty cement ton bag 3 from the lifting hook 14 and hooks it onto the specified part of the next cement ton bag 3.

DETAILED DESCRIPTION OF THE INVENTION

[0008] One embodiment of the present invention will be explained with reference to the drawings. 1 is a batcher plant equipped with a cement silo 2, and further equipped with a crane 4 that transports and supplies cement ton bags 3 to the cement silo 2 (Figure 1). The batcher plant 1 may have any configuration, and an example thereof will be described below. The batcher plant 1 has a cement silo 2 installed on top of a plant frame 5, and a crane 4 installed at a predetermined position on the plant frame 5 above the cement silo 2. A roughly flat work area 8 is provided on top of the plant frame 5 above the cement silo 2, and below the cement silo 2 are a mixer 6 that mixes water and cement to produce cement milk, and an agitator 7 that temporarily stores the cement milk produced by the mixer 6 while stirring it to prevent it from solidifying. 9 is a water supply tank that stores water to be supplied to the mixer 6.

[0009] The crane 4 has a support 12D of a vertical mast 10 fixedly attached to the plant frame 5, a rotating shaft 12E of the mast 10 attached to the support 12D via a swivel mechanism 12 so as to be rotatable only, and the base of a swivel arm 11 that protrudes laterally is attached to a predetermined position on the top of the mast 10. A swivel mechanism 12 that rotates the swivel arm 11 around the center of the mast 10 is provided on the base side of the mast 10 (Figs. 4 and 5). The configuration of the swivel mechanism 12 is arbitrary, and is configured by providing a rotary gear 12A at the base of the rotary shaft 12E of the mast 10, and meshing the rotary gear 12A with a gear 12C of a swivel motor 12B for swivel. In addition, a speed reducing gear may be engaged between the rotary gear 12A and the gear 12C of the rotation motor 12B.

[0010] A hoist crane 13 that moves in the longitudinal direction of the swivel arm 11 is attached to the swivel arm 11 (Figure 1). The hoist crane 13 is configured so that a wire 15 having a lifting hook 14 is wound around a wire drum 16, and a motor 17 is provided to drive the wire drum 16. The motor 17 rotates the wire drum 16 to pay out and rewind the wire 15. In FIG. 6 and other figures, the wire drum 16 is housed in a drum case 16A. The hoist crane 13 has a drum case 16A and a motor 17 attached to a support member 18, and a travel motor 19, a lower roller 19A that is driven to rotate by the travel motor 19, and a freely rotating upper roller 19B attached to the support member 18. 19C is a reducer that reduces the rotation of the travel motor 19 and transmits it. The lower roller 19A and the upper roller 19B clamp the swivel arm 11 from both the top and bottom, and by driving and rotating the lower roller 19A by the movement motor 19, the support member 18 of the hoist crane 13 is moved in the longitudinal direction of the swivel arm 11.

[0011] Reference numeral 20 denotes a plant unit control panel of the batcher plant 1, and the plant unit control panel 20 is provided with an operation touch panel 21 that displays a plurality of cement ton bags 3 that have been placed in advance around the batcher plant 1 and sets the transportation order of the displayed plurality of cement ton bags 3. In Figure 1, 23 is a crane automatic operation remote control that automatically operates a crane 4 installed at a predetermined position, and 25 is an inlet installed in the work area 8, and the inlet 25 is closed with a cover member 25A except when cement is being supplied. To explain an example of a cement supply work method, a plurality of cement ton bags 3 filled with cement are arranged around the batcher plant 1 in advance (Figures 11 and 13), and the plurality of arranged cement ton bags 3 are displayed on the operation touch panel 21 of the plant unit control panel 20 of the batcher plant 1 (Figures 12 and 13). The portion of the operation touch panel 21 corresponding to the displayed cement ton bag 3 is touched to set the transport order of the plurality of cement ton bags 3.

[0012] When the operation touch panel 21 is touched, the position information based on the X and Y coordinates and the transport order are set as shown by the circled numbers in FIG. The automatic operation of the crane 4 is started using a crane automatic control remote control 23 (Figures 1 and 15) installed in a predetermined position, and the mast 10 is rotated using the swivel mechanism 12 to rotate the swivel arm 11 to a predetermined angle around the mast 10 so that the lifting hook 14 is positioned above the cement ton bag 3 in the transport setting order, and the swivel arm 11 is then automatically stopped.Next, the hoist crane 13 is moved in the lengthwise direction of the swivel arm 11 and automatically stopped, and the lifting hook 14 is lowered to a predetermined height above the set cement ton bag 3 and stopped, and the automatic operation of the crane 4 is then automatically stopped. Then, when the lifting hook 14 is positioned at a predetermined height above the set cement ton bag 3, the automatic operation of the crane 4 is automatically stopped, allowing the worker to easily engage the lifting hook 14 at a predetermined part of the cement ton bag 3.

[0013] In this way, when automating the operation of the clay 4 to move the placed cement ton bag 3 to the inlet 25 of the cement silo 2, the lifting hook 14 at an arbitrary position is automatically moved to the cement ton bag 3, and then the automatic operation is stopped (interrupted) and the lifting hook 14 is manually engaged with the cement ton bag 3. Therefore, by automatically suspending the automatic control during automatic operation of the crane 4 and manually engaging the lifting hook 14 with the cement ton bag 3, the overall automation program for the crane 4 can be simplified and the creation of the overall automation program can be made easier.

[0014] When the worker engages the lifting hook 14 at a predetermined part of the cement ton bag 3 and again starts automatic operation of the crane 4 using the crane automatic operation remote control 23, the wire drum 16 winds up the wire 15 and the lifting hook 14 raises the cement ton bag 3 to a predetermined height. Once the cement ton bag 3 has been raised to the predetermined height, the swivel arm 11 is rotated to an angle above the inlet 25 of the cement silo 2, and the hoist crane 13 is moved to above the inlet 25. When the hoist crane 13 moves above the inlet 25, the cement ton bag 3 is automatically lowered and cement is poured into the inlet 25 of the cement ton bag 3, and the automatic crane operation for transporting and supplying cement is temporarily terminated.

[0015] Then, when the crane automatic control remote control 23 is used again to start automatic control of the crane 4, the lifting hook 14 located above the inlet 25 automatically moves to the next cement ton bag 3 in the set transport order and lowers it to the specified height (the empty cement ton bag 3 is disengaged from the lifting hook 14 when it is engaged), then the automatic control is temporarily stopped (interrupted), the lifting hook 14 is manually engaged with the cement ton bag 3, and the automatic control of the crane 4 is resumed again, the cement ton bag 3 is automatically transported to the inlet 25, and this operation is repeated to transport and supply the cement ton bags 3.

[0016] Furthermore, if, at the start of work, the lifting hook 14 is already positioned above the cement ton bag 3 in the transport setting order because, for example, the previous replenishment work is continuing, the worker can engage the lifting hook 14 at a specified part of the cement ton bag 3 without rotating the swivel arm 11, and start automatic operation of the crane 4 using the crane automatic operation remote control 23. When automatic operation begins, the lifting hook 14 raises the cement ton bag 3 and automatically stops it. Next, the swivel arm 11 is automatically rotated to above the inlet 25 of the cement silo 2, the hoist crane 13 is automatically stopped above the inlet 25, the cement ton bag 3 is automatically lowered, and cement is automatically poured into the inlet 25 of the cement ton bag 3. The lifting hook 14 is then automatically moved so that it is positioned above the next cement ton bag 3 in the transport setting order, and the cement replenishment work is repeated in automatic operation.

[0017] In this way, when the lifting hook 14 is engaged with the cement ton bag 3, the cement ton bag 3 is automatically transported to the inlet 25, automatically released, and the lifting hook 14 is moved above the next cement ton bag 3 in the transport setting order, but the work start and end conditions can be determined arbitrarily by operating the crane automatic control remote control 23. That is, after the last cement ton bag 3 is transported, the hanging hook 14 can be operated arbitrarily, for example, by leaving it on standby above the insertion port 25. The automatic operation of the crane 4 is performed by providing a rotation position detection unit 30 on the mast 10 that detects the rotation position of the rotation arm 11, a distance (radius) detection unit 31 on the mast 10 that detects the movement distance of the hoist crane 13 relative to the mast 10, and a height detection unit 32 on the hoist crane 13 that detects the height position of the lifting hook 14, and the control unit 33 performs calculations based on these detection data to automatically control the system. The turning position detection unit 30 may have any configuration, and may be configured with, for example, a gyro sensor or a potentiometer.

[0018] The distance detection unit 31 may have any configuration, and may be configured, for example, by a so-called laser range finder. The height detection unit 32 may have any configuration. In this embodiment, it is provided in the drum case 16A and calculates the height of the hanging hook 14 from the movement speed and time of the wire 15, but it may also be configured, for example, by a so-called long-distance photoelectric sensor. In addition, a weight measuring unit 36 ​​that constantly measures the weight of the cement ton bag 3 is detachably attached to the hanging hook 14 or the wire 15 near the hanging hook 14, and the weight measuring unit 36 ​​sends the weight measured in real time to the control unit 33, which controls the process to proceed to the next step. For example, when cement is being poured into the inlet 25, the weight is constantly measured and the cement in the cement ton bag 3 is released into the inlet 25, and when the cement ton bag 3 becomes empty, an alarm means 37 notifies the user of this based on the value detected by the weight measuring unit 36.

[0019] Furthermore, when the weight measuring unit 36 ​​detects a weight equal to or greater than the set weight of the cement ton bag 3 at the start of transportation, the control unit 33 issues a warning by the notification means 37 based on the detected value of the weight measuring unit 36 ​​. In this case, although not shown in the drawings, the notification means 37 is configured to notify by sounding a speaker or displaying on a monitor. The configuration of the crane autopilot remote control 23 is arbitrary, but as an example, it is provided with an autopilot start switch 40, an autopilot pause switch 41, a next process switch 42 for moving to the next process, and an autopilot end switch 43, and the crane autopilot remote control 23 is connected to the control unit 33 by wire or wirelessly. The crane automatic operation remote control 23 is provided on the plant unit control panel 20, the silo unit control panel 45, and the hoist crane 13, and is configured to be operable at each location.

[0020] In addition, a crane remote control 23A may be connected to the hoist crane 13 so that, in addition to operating the crane automatic control remote control 23, fine adjustments to the movement of the hoist crane 13 and the up and down operation of the lifting hook 14 can be performed. The inlet 25 is provided with a slitting cutter 50 for opening the lower part of the cement ton bag 3, and when the cement ton bag 3 is lowered, the weight of the cement ton bag 3 automatically opens the part in contact with the slitting cutter 50. In addition, a transmitting tag 56 that transmits installation location information may be attached to the lifting portion 55 of the cement ton bag 3, and the location information may be received by a receiving unit 57 installed at a predetermined location on the rotating arm 11, thereby automatically controlling the crane 4.

[0021] (Operation of the embodiment) The present invention has the above-described configuration, and the batcher plant 1 is transported and installed at a work site for pile driving or soil improvement or near the work site. The batcher plant 1 is equipped with a crane 4 for transporting cement ton bags 3, so a plurality of cement ton bags 3 filled with cement are placed in advance at predetermined positions around the batcher plant 1, and the plurality of placed cement ton bags 3 are displayed on the operation touch panel 21 of the plant unit control panel 20 of the batcher plant 1, and the operation touch panel 21 for the portion of the displayed cement ton bag 3 is touched to set the transport order of the plurality of cement ton bags 3.

[0022] The automatic operation of the crane 4 is started using a crane automatic operation remote control 23 installed in a predetermined position, and the mast 10 is rotated using the swivel mechanism 12 to rotate the swivel arm 11 around the center of the mast 10 so that the lifting hook 14 is positioned above the cement ton bag 3 in the transport setting order, the hoist crane 13 is moved in the length direction of the swivel arm 11, the lifting hook 14 is lowered above the set cement ton bag 3, and the automatic operation of the crane 4 is temporarily stopped (interrupted). Therefore, by manually performing the most difficult task of automatically operating the crane 4, which involves moving the lifting hook 14 to the cement ton bag 3 in its designated position and transporting the cement ton bag 3 to the inlet 25 and engaging the lifting hook 14 with the cement ton bag 3 during the automation process, the automatic operation of the crane 4 can be simplified, reducing work time and costs as the work can be done by one person instead of two.

[0023] The worker engages the lifting hook 14 at a predetermined part of the cement ton bag 3 and again starts automatic operation of the crane 4 using the crane automatic operation remote control 23, causing the wire drum 16 to wind up the wire 15 and the lifting hook 14 to raise the cement ton bag 3 to a predetermined height.Once the cement ton bag 3 has risen, the swivel arm 11 automatically rotates to above the inlet 25 of the cement silo 2, and the hoist crane 13 is moved to above the inlet 25. When the hoist crane 13 moves above the inlet 25, the cement ton bag 3 is automatically lowered and cement is poured into the inlet 25 of the cement ton bag 3, and the automatic crane operation for transporting and supplying cement is temporarily terminated. Then, the crane automatic operation remote controller 23 is again operated to start the automatic operation of the crane 4, and the crane 4 is automatically operated to repeat the work of transporting and supplying the cement ton bag 3.

[0024] The automatic operation of the crane 4 is performed by providing a rotation position detection unit 30 on the mast 10 that detects the rotation position of the rotation arm 11, a distance (radius) detection unit 31 on the mast 10 that detects the movement distance of the hoist crane 13 relative to the mast 10, and a height detection unit 32 on the hoist crane 13 that detects the height position of the lifting hook 14, and the detection data of the rotation position detection unit 30, distance detection unit 31 and height detection unit 32 are calculated by a control unit 33 to perform automatic control. A weight measuring unit 36 ​​that measures the weight of the cement ton bag 3 is provided on the hanging hook 14 or the wire 15 near the hanging hook 14, and when the weight measuring unit 36 ​​detects a weight greater than the set value, the control unit 33 issues a warning based on the detection value of the weight measuring unit 36.

[0025] In addition, when the cement in the cement ton bag 3 is released into the inlet 25 of the cement silo 2 and the cement ton bag 3 becomes empty, an alert is issued based on the detection value of the weight measuring unit 36, allowing the worker to proceed to the next process.When the next process switch 42 on the crane automatic control remote control 23 is operated, the lifting hook 14 of the hoist crane 13 is automatically lowered above the next cement ton bag 3 that has been set in advance, and the cement dispensing work is carried out. The crane autopilot remote control 23 is provided with an autopilot start switch 40, an autopilot pause switch 41, a next process switch 42 for moving to the next process, and an autopilot end switch 43, and since the crane autopilot remote control 23 is connected to the control unit 33 by wire or wirelessly, the crane 4 can be operated from a location away from the batcher plant 1.

[0026] The crane automatic operation remote control 23 is hung from the plant unit control panel 20, the silo unit control panel 45, and the hoist crane 13, so that it can be operated in the most suitable place, improving operability. The inlet 25 is provided with a slitting cutter 50 for opening the bottom of the cement ton bag 3, so when the cement ton bag 3 is lowered, the weight of the cement ton bag 3 automatically tears open the part in contact with the slitting cutter 50, and cement is poured into the inlet 25. When a transmitting tag 56 that transmits installation location information is attached to the lifting part 55 of the cement ton bag 3, the location information, etc. is received from the transmitting tag 56 of the cement ton bag 3 by a receiving unit 57 installed at a predetermined location on the rotating arm 11. Therefore, if the insertion order, etc. is input and set into the transmitting tag 56, the operation of the control unit 33 when automatically controlling the crane 4 can be simplified, and operability can be improved.

[0027] That is, when automatic operation of the crane 4 is started by the crane automatic operation remote control 23 installed at a predetermined position, the receiver 57 receives the installation position information transmitted by the transmitting tag 56 so that the lifting hook 14 is positioned above the cement ton bag 3 in the transportation setting order, and the lifting hook 14 is moved to above the cement ton bag 3 in the transportation setting order, and the worker engages the lifting hook 14 at a predetermined part of the cement ton bag 3, and when automatic operation of the crane 4 is started again by the crane automatic operation remote control 23, the wire drum 16 reels in the wire 15, and the lifting hook 14 raises the cement ton bag 3 to a predetermined height, the swivel arm 11 is swung to above the inlet 25 of the cement silo 2, and the cement ton bag 3 is transported to above the inlet 25, and the lifting hook 14 is then raised toward the inlet 25. 4 is lowered, and the cement ton bag 3 is opened by a slitting cutter 50 using its own weight, starting the pouring of cement. The weight measuring unit 36 ​​constantly measures the weight of the cement ton bag 3. When the release of the cement in the cement ton bag 3 into the pouring port 25 is completed and the weight measuring unit 36 ​​detects this, the lifting hook 14 is automatically raised and automatically raised, rotated and lowered to above the next cement ton bag 3 based on the preset transport order. Once the lifting hook 14 has been lowered above the cement ton bag 3, the automatic operation of the crane 4 is stopped, and the worker removes the empty cement ton bag 3 from the lifting hook 14 and hooks it to the specified part of the next cement ton bag 3. The automatic operation of the crane 4 is then started again using the crane automatic control remote control 23, and this process is repeated to perform the cement replenishment work.

[0028] In addition, since the calculation is performed using the rotation position detection unit 30, distance detection unit 31, or height detection unit 32, even if there is a slight change in weight of each cement ton bag 3, it is possible to reliably transport the cement ton bags 3 to the inlet 25 of the cement silo 2. In addition, the control unit 33 automatically and efficiently controls the crane 4 to the location of the insertion port 25 using the rotation position detection unit 30, so work can be done faster than if a person were to operate the crane 4, improving work efficiency.

[0029] A weight measuring unit 36 ​​that measures the mass of the cement ton bag 3 is installed on the lifting hook 14 or wire 15, so the load of the cement ton bag 3 during transportation by the crane 4 can be determined, and if the mass measured is greater than the maximum lifting load, an alarm can be issued. In addition, when the cement has been poured into the inlet 25 of the cement silo 2, the mass can be measured while pouring, so that the cement can be poured automatically even if there is no worker at the inlet 25 of the cement ton bag 3. Since the hoist crane 13 itself is provided with a height detection unit 32, if a person enters the vicinity of the cement ton bag 3, the hoist crane 13 can be stopped, thereby improving safety.
