[0036] Hereinafter, Figure 1 the paper surface outer side of the container pouring device 100 in Figure 3 is referred to as the front side, and the paper surface outer side of the container pouring device 100 in

[0037] is referred to as the rear side. Figures 1 to 4 As shown in , the container pouring device 100 of the present application is in a substantially gantry shape, which is provided with: a base 30 in a flat plate shape, on the upper surface of which two slide ways 301 for sliding a workpiece (in the present embodiment, a ton barrel storing paint or glue, etc.) as an object of lifting and overturning and a stopper 302 provided at a predetermined position on the end side of the two slide ways 301 and stopping the workpiece are formed, and further, on the bottom surface of the base 30, a universal wheel 303 having a locking function is installed at each of the four corner portions; a lifting mechanism 20 provided with a pair of hydraulic cylinders 201 vertically arranged and spaced apart by a predetermined interval, the hydraulic cylinders 201 each including a cylinder body 202 and a hydraulic rod 203 inserted into the cylinder body 202 in a manner capable of being extended and retracted with respect to the cylinder body 202; a cross beam 10 fixed to the end (upper end) of the hydraulic rod 203; a pair of support arms 11 fixed to the inner side of the hydraulic rod 203 in the length direction of the cross beam 10 at a predetermined interval and each vertically and downwardly hanging from the cross beam 10; and an overturning mechanism 12 installed at the end (lower end) of one support arm 11 for overturning the workpiece.

[0038] Considering the weight of the ton barrel, it is preferable that the cross beam and the support arm are integrally formed, for example, by casting, of course, not limited thereto, but the support arm and the cross beam can also be welded together by welding.

[0039] The overturning mechanism 12 is provided with a clamping portion 13 and an overturning controller 14.

[0040] Figure 5 The clamping portion 13 is provided with: a hoop 131 as a holding member, which is detachably installed between the pair of support arms 11, can be separated in the circumferential direction, and is used to hold the ton barrel 50 (see Figure 6 ) from the outer periphery in the circumferential direction; and a locking buckle 132 as a locking member, which is installed on the outer peripheral surface of the hoop 131 and is used to lock the hoop 131. For example, in the case of installing the ton barrel 50, as long as the ton barrel 50 is put in after the hoop 131 is opened in the circumferential direction and the hoop 131 is locked by the locking buckle 132.

[0041] The overturning controller 14 is installed on the outer side of one support arm 11, and in Embodiment 1 is provided with a rotary motor 141 and an operation handle 142 connected to the rotary motor 141.

[0042] like Figures 2 to 4 As shown, protrusions 135 are formed on the two sides (at 180 degrees) facing each other on the outer peripheral surface of the hoop 131. Multiple grooves 133 arranged in height are formed on each protrusion 135. The multiple grooves 133 on both sides are at the same height from top to bottom.

[0043] The rotation shaft of the rotary motor 141 is connected to a hoop rotation connector 134 mounted on the hoop 131 of the support arm 11 on which the rotary motor 141 is mounted. At the lower end and outer side of the other support arm 11 where the rotary motor is not mounted, at the same height as the hoop rotation connector 134, a fixing pin 15 is installed (i.e., the height of the axis of the hoop rotation connector 134 and the fixing pin 15 are aligned). The hoop rotation connector 134 and the fixing pin 15 serve as the rotation shaft of the hoop, respectively inserted into two left and right grooves 133 at the same height (hereinafter referred to as corresponding in the height direction). That is, the hoop rotation connector 134 and the fixing pin 15 define the pivot axis of the hoop (ton container).

[0044] Thus, the rotation of the rotating shaft of the rotary motor 141 causes the hoop 131 to rotate around the pivot axis. In addition, the operating handle 142 is engraved with a scale, and the operator can rotate the operating handle 142 to rotate the rotary motor 141 by a specified number of revolutions.

[0045] Alternatively, instead of a control handle, the rotation angle of the rotary motor can be output to a display screen, allowing the operator to obtain the number of rotations. When precise control of the rotation number is not required, the operator can also visually adjust the rotation angle of the ton container.

[0046] In this embodiment, the rotary motor 141 is a self-locking motor (a motor with an automatic locking function) that can hold the workpiece at the required angle.

[0047] In this embodiment, since multiple grooves 133 arranged in height are formed on the protrusions 135 on both sides, the height of the hoop 131 can be finely adjusted by inserting the hoop rotation connector 134 and the fixing pin 15 into the corresponding grooves 133 in the height direction, and the hoop 131 can be fixed at this height position by the fixing pin 15.

[0048] In addition, in actual processing, the actual size of the workpiece may be slightly different due to non-standard parts or processing errors. If it is the conventional clamping part 13, the radial dimension cannot be adjusted, so the workpiece may slide or even fail to be clamped because the radial dimension of the workpiece does not match the radial dimension of the hoop 131.

[0049] In the present embodiment, the above problem can be solved by replacing the clamping portion 13 of different sizes. Specifically, for example, when the radial dimension of the ton barrel 50 is slightly smaller than the radial dimension of the already installed collar 131, the collar 131 of a corresponding size can be replaced. Since the newly replaced collar 131 has a slightly smaller radial dimension, the depth of the insertion of the fixing pin 15 into the groove can be adjusted by adding a gasket. Conversely, when the radial dimension of the ton barrel 50 is slightly larger than the radial dimension of the already installed collar 131, the depth of the insertion of the fixing pin 15 into the groove can be adjusted by reducing the gasket.

[0050] Therefore, the container pouring device 100 of the present application can quickly realize the clamping and fixing of containers of different sizes, and the clamping is reliable.

[0051] In the present embodiment, in order to realize the adjustment of the height direction and the radial direction of the clamping portion, the structure of the collar rotating connecting piece 134 and the fixing pin 15 respectively inserted into different grooves 133 in the height direction is adopted, of course, not limited thereto, as long as the rotating shaft of the rotating motor is connected with the gripping piece, and the gripping piece is rotated by the rotating shaft, different structures can also be adopted.

[0052] In addition, in the present embodiment, the pair of supporting arms 11 are respectively composed of a supporting arm upper section 11a and a supporting arm lower section 11b, the supporting arm lower section 11b is inserted into the supporting arm upper section 11a in a telescopic manner relative to the supporting arm upper section 11a, and can be fixed to the supporting arm upper section 11a by a fixing piece 111. By adjusting the telescopic extension of the supporting arm lower section 11b relative to the supporting arm upper section 11a, the height of the collar 131 (ton barrel 50) can be further adjusted, and after the height is adjusted, the fixing piece 111 is tightened.

[0053] In the present embodiment, the lifting mechanism 20 adopts a known pneumatic hydraulic mechanism, that is, the transmission of the hydraulic cylinder is controlled by compressed air, more specifically, the control element in the hydraulic system is a pneumatic valve, and the opening and closing action of the pneumatic valve is controlled by using air pressure signals, when the air pressure signal reaches a certain value, the pneumatic valve is opened or closed, thereby controlling the direction and pressure of the liquid flow in the hydraulic system.

[0054] Of course, not limited thereto, a common hydraulic transmission mechanism can also be adopted, as long as it can bear the weight of the overturning object and lift.

[0055] Since the lifting mechanism 20 of the present embodiment adopts a known pneumatic hydraulic mechanism, the internal structure and principle of the pneumatic hydraulic mechanism are omitted, and only the structure of the pneumatic element is described below.

[0056] The lifting mechanism 20 has, in addition to the hydraulic cylinder 201, an air pressure stabilizer 21, an air device control section 22, and a compressed air pipe 23.

[0057] The air pressure stabilizer 21 and the air device control section 22 are provided in one of the two cylinders 202 (in the side close to the rotary motor in the drawing, but can be the other side).

[0058] As shown in Figure 3 , the air pressure stabilizer 21 has a safety valve 211 that automatically releases pressure when the pressure of the input compressed air exceeds a set threshold, a pressure gauge 212 that detects the pressure of the input compressed air, and a filter 213 that filters the input compressed air.

[0059] The air device control section 22 controls the flow direction and pressure of the working fluid in the hydraulic cylinder 201 using compressed air.

[0060] One end of the compressed air pipe 23 is connected to a compressed air source (not shown), and the other end is connected to the hydraulic cylinder 201, so that the compressed air input from the compressed air source flows into the hydraulic cylinder 201 in sequence through the air pressure stabilizer 21 and the air device control section 22.

[0061] In addition, the compressed air pipe 23 is also connected between the two hydraulic cylinders 201 and is covered by the tubular stopper 302, i.e., the compressed air pipe 23 passes through the tubular stopper 302 between the two hydraulic cylinders 201.

[0062] In this embodiment, the portion of the compressed air pipe 23 between the two hydraulic cylinders 201 is covered by the tubular stopper 302, which can prevent the stopper and the compressed air pipe from interfering with each other, has a simple structure and saves space, and of course the two can be provided separately.

[0063] In addition, in the embodiment, the container tipping device 100 has a movable base 30 for the sake of convenience of movement and operation, but is not limited thereto, and of course the entire container tipping device 100 can be provided as a fixed type that cannot be moved.

[0064] Hereinafter, the operation process of lifting and turning the workpiece by the container tipping device 100 will be described in detail.

[0065] Figure 5 and Figure 6 indicates that the ton barrel 50 as a workpiece is clamped in the hoop 131 and the hoop 131 (ton barrel 50) is rotated 90 degrees from the horizontal state to the front of the paper, Figures 1 to 4 is a perspective view, Figure 5 is a side view. Figure 6 is a side view.

[0066] First, inFigure 1 In the state shown in FIG. 6, the container tipping device 100 is moved to the vicinity of the ton barrel 50 and the universal wheel 303 is locked, the hoop 131 is opened in the circumferential direction, and the ton barrel 50 is slid along the two slides 301 provided on the base 30 in an erected posture on the upper surface of the base 30, and the ton barrel 50 is stopped by the stopper 302 to ensure that the ton barrel 50 does not slide out of the base 30.

[0067] After the ton barrel 50 is inserted into the hoop 131, it is locked by the locking buckle 132. Thus, the clamping step is completed.

[0068] Next, the lifting step is entered.

[0069] As shown in FIG. 7, compressed air from a compressed air source (not shown) enters the compressed air line 23, and flows into the hydraulic cylinder 201 in sequence through the air source pressure stabilizer 21 and the pneumatic device control section 22. Figure 3 Figure 4 As described above, in the present embodiment, the lifting mechanism 20 employs a known pneumatic hydraulic mechanism, and by using the compressed air flowing into the two cylinder bodies 202 to control the pneumatic valve provided in the cylinder body 202, the flow direction and pressure of the working liquid can be switched.

[0070] By operating the pneumatic device adjustment handle 22, the extension, retraction and pressure holding of the hydraulic rod 203 relative to the cylinder body 202 can be controlled.

[0071] For example, when the pneumatic device adjustment handle 22 is in the lower position (vertically downward), the working liquid flows from bottom to top, pushing the hydraulic rod 203 to extend relative to the cylinder body 202, and thus the ton barrel 50 rises.

[0072] When the pneumatic device adjustment handle 22 is in the upper position (vertically upward), the working liquid flows from top to bottom, causing the hydraulic rod 203 to retract relative to the cylinder body 202, and thus the ton barrel 50 descends.

[0073] When it is necessary to keep the ton barrel 50 at a certain height, the pneumatic device adjustment handle 22 is placed in the middle position (horizontally), and the working liquid is not allowed to flow, and thus the ton barrel 50 is kept at a certain height.

[0074] After the ton barrel 50 is kept at the desired height by the lifting mechanism 20, the overturning step is entered.

[0075] Of course, before clamping the ton barrel 50, the height of the hoop 131 can also be adjusted by inserting the fixed pin 15 and the hoop rotating link 134 into another pair of grooves 133 of different heights, and / or the height of the support arm lower section 11 can be adjusted by pulling out the fixed bolt 111.

[0076] Of course, before clamping the ton barrel 50, the height of the hoop 131 can also be adjusted by inserting the fixed pin 15 and the hoop rotating link 134 into another pair of grooves 133 of different heights, and / or the height of the support arm lower section 11 can be adjusted by pulling out the fixed bolt 111.

[0077] ​The operator rotates the operation handle 142, controls the number of rotations of the rotating motor 141 according to the scale engraved on the operation handle 142, and rotates the hoop 131 connected to the rotating shaft by a predetermined angle.

[0078] For example, as shown in Figure 5 , Figure 6 , the hoop 131 with the ton barrel 50 clamped is rotated 90 degrees from the position shown in Figures 1 to 4 to the front of the paper and kept in a horizontal posture.

[0079] Here, the horizontal posture is only an example, and the container pouring device 100 of the present application can turn the workpiece 360 degrees or even more.

[0080] When the ton barrel 50 is kept in a proper posture, the liquid in the ton barrel 50 is output to the outside through the discharge pipe 60.

[0081] At this time, the outflow speed of the liquid in the ton barrel 50 can be controlled by controlling the angle of inclination of the ton barrel 50.

[0082] Of course, the operation sequence of the above clamping step, lifting step and turning step is only an example, for example, the operator can appropriately change according to the height relationship between the workpiece and the hoop and the current posture of the hoop. The lifting step can be performed first, followed by the clamping step, and finally the turning step. The turning step can be performed first, followed by the clamping step, and then the lifting step and the turning step. In addition, the turning step can be performed simultaneously with the lifting step.

[0083] After discharging, the ton barrel 50 (which can be an empty ton barrel or a ton barrel with remaining liquid) is turned to an upright state, and then from the turning position (rising position) to the descending position, and then the ton barrel is loosened, and then the ton barrel is removed from the base.

[0084] As described above, according to the container pouring device of embodiment 1, it is easy to operate, safe, and can quickly achieve clamping and fixing of containers of different sizes, and the clamping is firm, and the container bottom can not be left.

[0085] In addition, by controlling the outflow speed of the liquid in the ton barrel 50, precise discharge control can be achieved.

[0086] Therefore, the container pouring device of the present application can balance the versatility, convenience and safety, and can accurately control the discharge.

[0087] Example 2

[0088] In addition, a charging pipe 70 can be connected to the ton barrel 50 according to actual needs, and a gas is input through the charging pipe 70 to push the liquid in the ton barrel 50 to be output from the discharging pipe 60. In order to ensure that the liquid in the ton barrel 50 is not oxidized, a non-active gas, such as nitrogen, is preferably used. At this time, the pressure of the gas input from the charging pipe 70 can be controlled through a pressure gauge (not shown), so that the outflow speed of the liquid in the ton barrel 50 can be controlled, and accurate discharging control can be further achieved.

[0089] Example 3

[0090] In addition, as preferred, a flow meter (not shown) can be connected to the discharging pipe 60, the flow rate is detected, and the detected output is displayed in real time on a display panel (not shown), so that the quantitative output of the liquid in the ton barrel 50 can be achieved.

[0091] Through quantitative output and control of the outflow speed, accurate discharging control can be further achieved.

[0092] In the present application, the large container refers to a container with a volume of 100L or more or a container with a total weight of 100kg or more, such as the ton barrel mentioned above, and the total weight of the ton barrel itself plus the content stored therein, such as paint or glue, is usually 200-300kg.

[0093] It should be noted that the above description of the container pouring device of the present application is exemplary, and the application object of the container pouring device of the present application is not limited to a ton barrel, and is not limited to a large container for storing liquid, but is a large container, and those skilled in the art can make various modifications and changes within a reasonable range.

[0094] In addition, it should be noted that in the above embodiment, the cross beam, the supporting arm, the cylinder body and the hoop of the container pouring device are made of cast iron coated with anti-rust paint, and the hydraulic rod is made of carbon steel. Of course, those skilled in the art can make reasonable choices from the environment of the use site, the cost of the device and the service life for each component of the container pouring device of the present application.

[0095] In addition, it should be noted that in the above embodiment, the lifting device uses a hydraulic cylinder, but it is not limited thereto, and any cylinder-piston device can be used.
