Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a container tilting device that automatically tilts a container in accordance with a decrease in a liquid material in the container.
[0002]
[Prior art]
For example, conventionally, in order to suck up the liquid in the drum can without waste, a drum having a small remaining amount is fixed obliquely by using a dedicated cart. This cart has a configuration in which one side of the lower surface of the bed on which the drum can is placed is fixed by a bearing, and the opposite side is horizontally supported by a stopper with a link mechanism, and the stopper is manually removed to tilt the bed. Thus, the posture of the drum can is changed.
[0003]
However, in this apparatus, a large force is required for the operation when the bed surface is inclined and the drum can is inclined. The determination as to whether or not the amount of liquid remaining in the container is low is made based on the idle shot sound of the pumping pump attached to the container (the sound of frequently operating the pump when idling). For this reason, the operator (operator) cannot leave the apparatus because the empty shot sound determines whether or not the liquid in the drum can is empty. Furthermore, in this apparatus, the horizontal and vertical movements of the upper surface of the drum can are large, and the pump unit is largely moved.
[0004]
Therefore, a device for changing the posture of the drum can without human intervention has been proposed (for example, see Patent Documents 1 and 2). This device has a mechanism in which a truck with wheels on which a drum can is placed is placed on a rail and the drum can is inclined by pushing the truck with an air cylinder.

[0006]
[Problems to be solved by the invention]
However, these devices still need to be monitored by an operator because of the need to operate the air cylinder. Further, since the air cylinder is used, the entire apparatus becomes complicated, and there is a problem of cost due to an increase in the number of parts.
[0007]
Therefore, the present invention has been made to solve the above-described problem, and it is an object of the present invention to provide an inexpensive container tilting apparatus which does not require the monitoring of an operator and can simplify the apparatus configuration.
[0008]
[Means for Solving the Problems]
The present invention places a container containing a liquid material on the upper surface, a mounting base having rollers mounted on the lower surface, a balance weight detachably mounted on the mounting base, and a concave curved parallel to each other. And a placed rail on which the loading base is placed, and the rolling of the rollers rolling on the rail causes the container on the loading base to automatically tilt as the liquid material decreases. Device.
[0009]
And in this container inclination apparatus, a balance weight is arrange | positioned back rather than the mounting position of a container, and the back and front roller. The container is mounted on the mounting base such that the center position of the container is ahead of the center position between the front and rear rollers. In addition, the center of gravity in the sliding direction of the mounting base when the liquid material is full (a state in which the liquid material is almost completely filled in the container), the mounting base, and the balance weight when the total weight of the mounting base and the balance weight is used. The position of the center of gravity of the mounting base in the sliding direction at the time of the total weight of the empty container, the mounting base, and the balance weight than the horizontal distance L1 from the position to the center position between the front and rear rollers. The horizontal distance L2 from the center to the center position between the front and rear rollers was increased.
[0010]
As described above, according to the present invention, the liquid content in the container is reduced by utilizing the change in the balance between the liquid weight in the container and the balance weight attached to the mounting base that slides on the concave rail. Since the container on the mounting base is automatically tilted, a driving source such as an air cylinder is not required, and the configuration of the apparatus is simplified. Further, since the container is automatically tilted without requiring the operation of the operator, the monitoring of the operator is not required.
[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, specific embodiments to which the present invention is applied will be described in detail with reference to the drawings.
[0012]
"Configuration of container tilting device"
As shown in FIGS. 1 to 6, the container inclining device according to the present embodiment mounts a drum 1 as a container on an upper surface and mounts first and second rollers 2 and 3 on a lower surface in a front and rear direction. The mounting base 4, a rail 5 on which the mounting base 4 is mounted and slidable, a bogie base 6 which is a main body for fixing the rail 5, and a balance weight 7 attached to the mounting base 4. It is configured.
[0013]
As shown in FIGS. 1 and 2, the bogie base 6 has a substantially rectangular frame (frame) structure in a plane, and forms a space for mounting the mounting base 4 in the center. Wheels 8, a handle frame 9, and a handle 10 fixed to the handle frame 9 are attached to the carriage base 6 so that an operator can move the container tilting device to a predetermined position. ing. Also, a rail 5 for mounting the mounting base 4 to be slidable is fixed to the carriage base 6. The rails 5 are curved so that the rail surfaces are concave in an arc shape, and are arranged at predetermined intervals so as to be parallel to each other. The rail surface of the rail 5 is formed as a locus describing an arc centered on the upper part of the drum 1.
[0014]
As shown in FIG. 7, a stopper 11 as a position fixing means for fixing the container tilting device at a predetermined position is attached to the cart base 6. The stopper 11 is composed of a shaft 13 which is inserted into a cylindrical stopper guide member 12 provided on the carriage base 6 and which can move up and down. An annular handle 14 for an operator to operate is formed at one end of the shaft 13. A pair of stopper pins 15 are formed on the shaft 13 so as to face each other in a direction orthogonal to the axial direction of the shaft 13.
[0015]
The stopper pins 15 are respectively engaged with a first engagement surface 16a and a second engagement surface 16b which are formed to have different heights in the axial direction of the stopper guide member 12. When the stopper pin 15 is engaged with the first engagement surface 16a, the tip of the shaft 13 comes into contact with the floor surface to prevent the carriage base 6 from moving, thereby fixing the position of the carriage base 6. On the other hand, when the stopper pin 15 is engaged with the second engagement surface 16b, the tip of the shaft 13 is separated from the floor surface, and the carriage base 6 can be moved.
[0016]
As shown in FIG. 8, the carriage base 6 is provided with a movement lock pin 17 which is a lock means for preventing movement of the mounting base 4 on the rail 5. The movement lock pin 17 is slidably attached to a slide guide member 18 fixed to the carriage base 6. A handle 19 is formed on the movable lock pin 17 so that the movable lock pin 17 can be slid by the operator.
[0017]
When the operator grips the handle 19 and slides the movable lock pin 17, as shown in FIG. 8, the distal end of the movable lock pin 17 contacts the upper surface 4 a of the mounting base 4, and The movement on the rail 5 is prevented. The upper surface 4a on which the drum 1 is mounted is made substantially parallel to the floor surface of the mounting base 4 which cannot be moved by the movable lock pin 17. For this reason, workability when the drum 1 is mounted on the mounting base 4 and when the drum 1 is taken out from the mounting base 4 are improved.
[0018]
Further, as shown in FIG. 9, a lifting prevention member 20 serving as a lifting prevention means for preventing the mounting base 4 from floating from the rail 5 is attached to the carriage base 6. The lifting prevention member 20 is made of, for example, a roller, and is rotatably attached to a fixing member 21 fixed to the carriage base 6 by a nut 22. For this reason, the bogie base 6 is pressed against the rail 5 by the lifting prevention member 20, and does not float off the rail 5.
[0019]
As shown in FIG. 10, the carriage base 6 is provided with a remaining amount detecting device 23 as remaining amount detecting means for detecting that the liquid in the drum 1 is empty. The remaining amount detecting device 23 comes into contact with a detection sensor main body 24 that is a detector, a detection sensor arm 25 connected to the detection sensor main body 24, and a roller 50 provided at a tip of the detection sensor arm 25. And a detection pin 26 attached to the mounting base 4 for rotating the detection sensor arm 25.
[0020]
The detection sensor main body 24 is mounted on a sensor mounting base 27 fixed to the carriage base 6. The detection sensor arm 25 is connected to the detection sensor main body 24, and is rotatable about a rotation shaft 28 in a direction indicated by an arrow in FIG. The detection sensor arm 25 is attached to the mounting base 4 when the mounting base 4 sliding on the rail 5 moves in a direction away from the balance weight 7 as the liquid material in the drum 1 gradually becomes empty. By being rotated by the attached detection pin 26, the detection sensor main body 24 is notified that the liquid in the drum 1 on the placement base 4 is empty.
[0021]
When this notification is transmitted to the detection sensor main body 24, an alarm sounds and informs the operator that the liquid material in the drum 1 is empty, and the pump unit 29 that pumps the liquid material in the drum 1 pumps up. Stop the operation. Thus, the operator can perform another operation at a location away from the container tilting device while pumping the liquid material in the drum 1.
[0022]
Further, a pole 31 for fixing a signal transmission cable 30 for transmitting a signal detected by the remaining amount detection device 23 to a control unit (not shown) is attached to the carriage base 6. The pole 31 is vertically mounted at a position near the tip of the mounting base 4 on the opposite side of the handle frame 9.
[0023]
The mounting base 4 is formed as a sufficiently rigid flat plate when the drum 1 filled with the liquid material is mounted. A first roller 2 and a second roller 3 that roll on the rail 5 are attached to the mounting base 4. The first roller 2 is a front roller provided at a position closer to the remaining amount detection device 23, and the second roller 3 is a rear roller provided at a position closer to the balance weight 7. Each of the first and second rollers 2 and 3 is rotatably mounted on the lower surface of the mounting base 4 by a roller mounting member 32.
[0024]
The mounting base 4 is provided with a mounting table 33 for positioning and mounting the drum 1. The mounting table 33 has a disk-shaped plate on which the drum 1 is mounted, and has a guide wall that rises up along the outer peripheral edge of the plate. The mounting table 33 is configured such that a rotation shaft attached to the mounting base 4 is inserted into an insertion hole provided at the center of the mounting table 33, and is rotatable with respect to the mounting base 4 as shown in FIG. Is rotatable by casters 35 fixed to the bottom surface. The mounting table 33 is supported so as not to be displaced from the mounting base 4 when the mounting base 4 described above slides on the rail 5 and tilts. By employing such a rotary mounting table 33, the pump unit 29 is always positioned at the center in the lateral direction of the apparatus due to the weight of the pump unit 29, and the liquid material 45 in the drum 1 is effectively pumped up. It becomes possible.
[0025]
As shown in FIG. 1, the mounting base 4 is provided with guide members 36 serving as a means for preventing the drum 1 from falling unnecessarily when the mounting base 4 is gradually inclined. Is formed. The guide members 36 are provided at front and rear positions opposite to each other with the drum 1 interposed therebetween, and support the drum 1 at a height position substantially at the center of the drum 1.
[0026]
As shown in FIG. 12, when the drum 1 is tilted, the mounting base 4 is attached to the rotating shaft formed on the mounting base 4 inserted in the insertion hole of the mounting table 33, as shown in FIG. A concentrated load relaxation preventing member 51 for preventing concentration of the first load is provided. The concentrated load relaxation prevention member 51 is rotatably attached to a support member 37 fixed to the upper surface 4a of the mounting base 4 by a nut 38. The concentrated load relaxation preventing member 51 has a roller shape, and comes into contact with the mounting table 33 and rotates with the rotation of the mounting table 33.
[0027]
Further, as shown in FIG. 10, the above-described detection pin 26 is attached to the mounting base 4. The detection pin 26 is fixed by a nut 40 to a pin support member 39 fixed at a position near the tip of the mounting base 4.
[0028]
Further, as shown in FIG. 3, a weight mounting pole 41 for mounting the balance weight 7 is mounted on the mounting base 4. The weight mounting pole 41 is fixed to the rear end of the mounting base 4 and is provided substantially perpendicular to the mounting base 4. A hook 42 for suspending the balance weight 7 is formed at the upper end of the weight mounting pole 41.
[0029]
The balance weight 7 is a weight having a predetermined weight, and has a hook portion 53 that is locked to the hook 42 of the weight mounting pole 41. The balance weight 7 is connected to the handle frame 9 by a chain 43 so that the balance weight 7 does not fall off the hook 42 and fall on the floor.
[0030]
The pump unit 29 is attached to a liquid substance discharge port 44 formed on the top surface 1a of the drum 1. As shown in FIG. 6, the pump unit 29 has a suction pipe 54 inserted into the inside of the drum 1 from the liquid substance discharge port 44, and a liquid material (for example, (Window washer liquid) 45. The pump unit 29 is supported by a chain 47 hooked on a pump unit hanging hook 46 provided at a work position where the liquid material 45 is taken out from the drum 1. For this reason, even if the drum 1 is inclined obliquely, the pump unit 29 does not fall.
[0031]
The pump unit 29 is connected with a hose 48 for transporting the sucked liquid material 45 to another container, a wiring 49 for supplying power to a power source, and the like.
[0032]
[Placement of drums, mounting base and balance weight]
Next, in the present embodiment, when the liquid substance 45 that has been fully filled is pumped up by the pump unit 29, the liquid weight of the liquid substance 45 and the balance change between the balance weight 7 are automatically used. In order to tilt the drum 1 by sliding the mounting base 4 on the rail 5, the position of the drum 1 and the position of the balance weight 7 are determined.
[0033]
As shown in FIG. 13, the center position Dc of the drum 1 in the sliding direction (the direction of the arrow X) of the mounting base 4 is the center position Rc between the front and rear first and second rollers 2 and 3. It is arranged so as to be located further forward (closer to the first roller 2 on the side away from the balance weight 7). The balance weight 7 is disposed behind the mounting position of the drum 1 and behind the front and rear first and second rollers 2 and 3.
[0034]
Further, in order to automatically tilt the drum 1 by sliding the mounting base 4 based on a change in the balance between the liquid weight of the liquid material 45 and the balance weight 7, the following settings are made. That is, when the drum 45, the mounting base 4 and the balance weight 7 are full of the liquid material 45, the first and second positions before and after the center of gravity Gf of the mounting base 4 in the sliding direction of the mounting base 4 are measured. When the total weight of the drum 1, the mounting base 4, and the balance weight 7 where the liquid material 45 is empty is smaller than the horizontal distance L1 to the center position Rc between the rollers 2 and 3 of the mounting base 4, The horizontal distance L2 from the center of gravity Ge in the sliding direction to the center position Rc between the front and rear first and second rollers 2 and 3 is increased.
[0035]
In FIG. 13, Gm indicates the position of the center of gravity of the mounting base 4 in the sliding direction when the weight of the drum 45, the mounting base 4, and the balance weight 7 is half of the liquid material 45. The center of gravity Gm of the total weight when the liquid material 45 is half is closer to the balance weight 7 side than the center position Rc between the front and rear first and second rollers 2 and 3.
[0036]
By setting the positional relationship between the drum 1, the mounting base 4, and the balance weight 7 in this manner, the liquid weight of the liquid 45 is reduced as the liquid 45 in the drum 1 is sucked up by the pump unit 29 and reduced. Due to the balance change of the balance weight 7, the mounting base 4 slides on the rail 5, and the drum 1 in FIG. 5 shifts from the substantially horizontal posture state to the inclined state in FIG.
[0037]
When the balance weight 7 is removed, the mounting base 4 is kept parallel regardless of the presence or absence of the drum 1. When the liquid material 45 is full, the mounting base 4 is maintained regardless of the presence of the balance weight 7. Kept parallel. Therefore, the work of replacing the drum 1 can be easily performed. In addition, the mounting base 4 is kept parallel when the empty weight can 1 is taken out by removing the balance weight 7 and when the drum 1 is full. In addition, if the work of replacing the drum 1 is performed after the slide movement of the mounting base 4 on the rail 5 is prevented by the movable lock pin 17, a reliable replacement operation can be performed.
[0038]
[Principle of automatic sliding tilt of the mounting base]
Next, the principle that the mounting base 4 slides on the rails 5 with the decrease of the liquid material 45 and automatically inclines the drum 1 mounted on the mounting base 4 will be described. First, how to determine the center of gravity Gf, Gm, Ge of the total weight of the drum 1, the mounting base 4, and the balance weight 7 in the sliding direction of the mounting base 4 will be described with reference to FIGS. . The alphabetic characters shown in FIGS. 14 and 15 and the following alphabetical characters represent the following contents.
[0039]
Wdf: Drum weight when full (drum weight including liquid weight)
Wdm: Weight of drum at half liquid
Wde: Weight of drum when empty
Wd: weight of mounting base (weight Ws of mounting base body + weight Wp of weight mounting pole)
Wb: Weight of balance weight
Note that there is a relation Wdf>Wdm> Wde between Wdf, Wdm and Wde.
[0040]

Lb: Horizontal distance from the mounting base tip to the mounting base center position Dd
Ls: horizontal distance from the tip of the mounting base to half the length of the entire mounting base
Lp: Horizontal distance from the tip of the mounting base to the center of the weight mounting pole
The placement base center position Dd is obtained by {(Ws × Ls) + (Wp × Lp) / (Ws + Wp)}.
[0041]
Lw: Horizontal distance from the tip of the mounting base to the center of the balance weight
Lf: Horizontal distance from the tip of the mounting base to Gf
Lm: Horizontal distance from the tip of the mounting base to Gm
Le: Horizontal distance from the tip of the mounting base to Ge
The center of gravity Gf when the tank is full can be obtained by calculating the aforementioned Lf. Lf is obtained by the following equation (1).
[0042]
Equation (1):
Lf = (Wd × Lb + Wdf × Ld + Wb × Lw) / (Wd + Wdf + Wb)
The position Gm of the center of gravity of the liquid material at half time can be obtained by calculating Lm described above. Lm is obtained by the following equation (2).
[0043]
Equation (2):
Lm = (Wd × Lb + Wdm × Ld + Wb × Lw) / (Wd + Wdm + Wb)
The position of the center of gravity Ge when the liquid material is empty can be obtained by calculating the above-mentioned Le. Le is obtained by the following equation (3).
[0044]
Equation (3):
Le = (Wd × Lb + Wde × Ld + Wb × Lw) / (Wd + Wde + Wb)
As described above, when the liquid material 45 in the drum 1 is gradually sucked out by the pump unit 29, the liquid weight of the liquid material 45 decreases, so that the drum 1 (including the liquid material 45) and the mounting base 4 And the position of the center of gravity of the total weight of the balance weight 7 gradually moves to the right position closer to the balance weight 7. Due to the change in the position of the center of gravity, the magnitudes of the respective forces applied to the front and rear first and second rollers 2 and 3 differ. Due to the difference in size, a force for moving the placement base 4 forward is generated, and the drum 1 can be tilted.
[0045]
Next, how to determine the magnitude of the force applied to the front and rear first and second rollers 2 and 3 will be described with reference to FIGS. The alphabetic characters shown in FIGS. 16 and 17 and the following alphabetical characters represent the following contents.
[0046]
Wf: Total weight of drum, loading base and balance weight when full
Wm: Total weight of drum, mounting base and balance weight when liquid is half
We: Total weight of empty liquid drum, mounting base and balance weight
Note that there is a relationship Wf>Wm> We between Wf, Wm and We.
[0047]

Lwf: horizontal distance from the center position of the front first roller 2 to the center of gravity Gf of the total weight when the tank is full
Lwm: Horizontal distance from the center of the first roller 2 in front to the center of gravity Gm of the total weight when the liquid is half
Lwe: horizontal distance from the center position of the front first roller 2 to the center of gravity Ge of the total weight when the liquid material is empty
WAf: vertical force applied to the front first roller 2 when the tank is full
WBf: vertical force applied to the rear second roller 3 when the tank is full
WAfx: Force on the rail slope horizontal direction applied to the front first roller 2 when the tank is full
WBfx: horizontal force on rail slope applied to rear second roller 3 when full
WAm: vertical force applied to the front first roller 2 when the liquid is halfway
WBm: vertical force applied to the rear second roller 3 when the liquid is half
WAmx: horizontal force on rail slope applied to front first roller 2 when liquid is halfway
WBmx: horizontal force on rail slope applied to rear second roller 3 when liquid is half
WAe: vertical force acting on the front first roller 2 when the liquid is empty
WBe: Vertical force applied to the rear second roller 3 when the liquid is empty
WAex: horizontal force on rail slope applied to front first roller 2 when liquid material is empty
WBex: horizontal force on rail slope applied to rear second roller 3 when liquid material is empty
Since the force required to slide the mounting base 4 is the difference between WAfx and WBfx, WAfx and WBfx are obtained. First, WAf and WBf are obtained. WAf and WBf are obtained by Expressions (4) and (5).
[0048]
Equation (4):
WAf = (Wf × (L−Lwf)) / L
Equation (5):
WBf = (Wf × Lwf) / L
Then, the force required to slide the mounting base 4 is obtained by Expressions (6) and (7).
[0049]
Equation (6):
WAfx = WAf · sin θA
Equation (7):
WBfx = WBf · sin θB
Then, the difference between WBfx and WAfx calculated by Expressions (6) and (7) is a force for sliding the mounting base 4. That is, the following equation (8) is a force Ff for sliding the mounting base 4 along the rail 5.
[0050]
Equation (8):
Ff = WBfx−WAfx
Similarly, WAm and WBm when the liquid material is half are obtained by the following equations (9) and (10). Further, the force required to slide the mounting base 4 is represented by Expressions (11) and (12), and the force Fm is represented by Expression (13).
[0051]
Equation (9):
WAm = (Wm × (L−Lwm)) / L
Equation (10):
WBm = (Wm × Lwm) / L
Equation (11):
WAmx = WAm · sin θA
Equation (12):
WBmx = WBm · sin θB
Equation (13):
Fm = WBmx-WAmx.
[0052]
Similarly, WAe and WBe when the liquid material is empty can be obtained by the following equations (14) and (15). Further, the force required to slide the mounting base 4 is represented by Expressions (16) and (17), and the force Fe is represented by Expression (18).
[0053]
Equation (14):
WAe = (We × (L-Lwe)) / L
Equation (15):
WBe = (We × Lwe) / L
Equation (16):
WAex = WAe · sin θA
Equation (17):
WBex = WBe · sin θB
Equation (18):
Fe = WBex−WAex.
[0054]
As can be seen from these equations, when the liquid material 45 in the drum 1 is sucked up by the pump unit 29 and the remaining amount gradually decreases, as shown in FIG. The center of gravity of the total weight of the drum 1 (including the liquid material 45), the mounting base 4 and the balance weight 7 is Gf, Gm, and Ge, and is gradually closer to the second roller 3, which is further away from the center of the rollers 2, 3. , The difference (Ff, Fm, Fe) in the horizontal force on the rail slope applied to the front and rear rollers 2 and 3 increases. That is, the relationship of the force for sliding the mounting base 4 along the rail 5 satisfies Ff <Fm <Fe.
[0055]
At this time, the horizontal distance from the center position Rc to the center of gravity Ge when the liquid is empty is shorter than the horizontal distance L1 from the center position Rc between the front and rear rollers 2 and 3 to the center of gravity Gf when the tank is full. Since L2 is large, the difference in moment at the position of the first roller 2 and the position of the second roller 3 when the liquid is empty is the difference between the moment at the position of the first roller 2 and the position of the second roller 3 when the liquid is full. Be larger. For this reason, the absolute value of the force for sliding the mounting base 4 along the rail 5 has a relationship of Ff <Fe. Accordingly, as the liquid material 45 is gradually sucked up by the pump unit 29, the mounting base 4 slides forward, and the drum 1 mounted on the mounting base 4 tilts.
[0056]
If there is no difference in the horizontal force applied to the front and rear first and second rollers 2 and 3 on the rail slope, the mounting base 4 is kept horizontal. In this embodiment, when the liquid material 45 is full, the mounting base 4 is kept substantially horizontal.
[0057]
[Description of operation]
Next, an operation of automatically tilting the drum 1 with the operation of sucking up the liquid material 45 in the drum 1 by the pump unit 29 will be described. First, the operator carries the container tilting device to a predetermined place, and then operates the stopper 11 to fix the container tilting device on the floor. Next, the operator slides the movement lock pin 17 to lock the slide movement of the mounting base 4 on the rail 5. In this locked state, the mounting base 4 has the upper surface 4a on which the drum 1 is mounted is substantially horizontal with respect to the floor surface, and is fixed while maintaining this horizontal state.
[0058]
Next, the operator places the drum 1 full of the liquid material 45 on the mounting table 33 provided on the mounting base 4. At this time, since the mounting base 4 is fixed and held in a substantially horizontal state, the water surface of the liquid material 45 in the drum 1 is also substantially horizontal. After attaching the pump unit 29 to the drum 1, the operator releases the lock by the stopper 11, turns on the power, and sucks up the liquid material 45 in the drum 1.
[0059]
When the liquid material 45 in the drum 1 is gradually sucked up, the mounting base 4 slides forward along the rail 5 according to the principle described above, and the drum 1 on the mounting base 4 tilts. At this time, the mounting base 4 is regulated by the lifting prevention member 20 so as not to float off the rail 5, so that the mounting base 4 can slide along the rail 5 in a stable state.
[0060]
Then, as shown in FIGS. 4 and 6, even when the liquid material 45 in the drum can 1 becomes small, the posture of the drum can 1 changes around its upper part. The movement of the hose 48 and the wiring 49 connected to the pump unit 29 can be minimized. Further, the pump unit 29 can suck up the liquid material 45 remaining in the drum 1 without remaining.
[0061]
When the mounting base 4 is further slid forward to rotate the detection sensor arm 25 provided on the carriage base 6 with the detection pin 26 attached to the mounting base 4, an alarm sounds and the operator is notified. To inform that the liquid material 45 in the drum 1 is empty. At the same time, the pumping operation of the pump unit 29 is automatically stopped. The operator listens to the alarm siren, comes to the place where the container tilting device is placed, unloads the emptied drum 1 from the mounting base 4, and then takes the next full liquid material 45. Is placed, and the above operation is repeated.
[0062]
