Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention is a can which is preferably used for overturning a can body in order to transfer liquid or powder contents such as pigment and solvent filled in the can body to a subdivided container or the like. Body overturn device.

[0002]

2. Description of the Related Art Generally, commercial pigments, solvents, etc. used as raw materials for cosmetics are delivered to a cosmetics factory in a state of being filled in a can such as a drum having a large internal volume. From the filled can and solvent-filled can, transfer the desired amount of pigment and solvent to a subdivision container, and mix the pigment and solvent transferred to the subdivision container appropriately to obtain a cosmetic product. It is designed to be manufactured.

[0003] Here, when the operation of transferring the contents such as the pigment and the solvent filled in the can body to the subdivision container (hereinafter referred to as the subdivision work), the contents are usually obtained by overturning the can body. BACKGROUND ART A can body overturning device is used that discharges an item into a small container little by little.

A conventional can body overturning device of this type is
Usually, a base and a can support that detachably supports the can and that is rotatably provided on the base via a support shaft; and a can support provided between the can support and the base. In general, a can body overturning mechanism and the like for rotating the can body with respect to the base by rotating the can body supporting means. Then, as the can body overturning mechanism, for example, a worm gear mechanism including a worm wheel and a worm that meshes with the worm wheel is applied. By rotating with this, the can body rolls over the base and discharges the contents into the subdivided containers.

However, in the can body overturning device using the handwheel as described above, the handwheel must be rotated with a high torque when a heavy can body such as a drum can is overturned. For this reason, a large burden is placed on the operator who performs the subdivision work, and the workability of the subdivision work is impaired, and the amount of overturning of the can body, which is performed to adjust the amount of the content discharged into the subdivision container, is adjusted. There is a problem that it is difficult to make fine adjustments.

On the other hand, a can body overturning device which is provided with a motor for driving a worm gear mechanism and which laterally rolls a can body through the worm gear mechanism by operating the motor by a switch operation is put to practical use.

[0007]

According to the can body overturning device having such a motor as a drive source, the output of the motor becomes a high torque by the worm gear mechanism to rotate the can body supporting means. Can switch over heavy cans such as drums by simply operating the switch.
The burden on the operator can be reduced and the workability of the subdivision work can be improved as compared with a can body overturning device using a handwheel.

However, in the above-described can body overturning device using a motor as a drive source, the roll speed of the can body is substantially constant, so that, for example, a small amount of content is transferred from the can body to the subdivision container during subdivision work. In some cases, it is difficult to finely adjust the amount of roll of the can body.

Further, the can body which rolls over at a constant speed is instantaneously stopped by the switching operation of the switch. Therefore, for example, even when the roll of the can body is stopped when a predetermined amount of the content is discharged into the subdivision container, There is a problem that the surplus contents are discharged to the subdivision container due to the fluctuation of the liquid surface of the container due to inertia, and the amount of the contents transferred into the subdivision container causes an error for each subdivision work. .

Furthermore, since the flow rate of the content discharged from the can to the subdivision container is substantially constant from the start to the end of the ejection, even after the transfer of the contents to the subdivision container is completed, the subdivision container is finished. Until the shaking of the inner liquid level subsides,
There is a problem in that it is not possible to perform accurate weighing of subdivided containers and it is not possible to shorten the time required for weighing work.

The present invention has been made in view of the above-mentioned problems of the prior art, and it is possible to improve the workability of the work of transferring the contents filled in the can body to the subdivision containers,
Moreover, it is an object of the present invention to provide a can body overturning device capable of transferring contents from a can body to a subdivision container in an accurate amount.

[0012]

In order to solve the above-mentioned problems, the present invention has a base and a can body which are detachably supported and are rotatably provided on the base via a support shaft. A can body supporting means, and a can body overturning mechanism which is provided between the can body supporting means and the base and which rolls the can body with respect to the base by rotating the can body supporting means. It is applied to a can body overturning device including a motor for driving the can body overturning mechanism and a overturning operation control means for controlling the operation of the motor.

The features of the configuration adopted by the present invention are as follows:
The overturning motion control means detects an operation member that rotates by a manual operation, a rotation amount, a rotation speed, and a rotation direction of the operation member, and outputs a detection signal according to the detected rotation amount, the rotation speed, and the rotation direction. And a motor drive circuit for outputting to the motor a forward / reverse drive signal having a lateral roll amount, a lateral roll speed and a lateral roll direction of the can body based on a detection signal from the signal generator circuit. .

[0014]

According to the above construction, when the operation member of the rollover motion control means is rotated, the rotation amount, rotation speed and rotation direction of the operation member are detected by the signal generating circuit, and the signal generating circuit detects the detected operation. It outputs a detection signal to the motor drive circuit according to the rotation amount, rotation speed, and rotation direction of the member. Then, the motor drive circuit outputs a forward / reverse drive signal having a lateral roll amount, lateral roll speed and lateral roll direction of the can body to a motor for driving the can body roll mechanism based on the detection signal from the signal generating circuit. Thereby, the operation of the motor is controlled according to the rotation amount, the rotation speed and the rotation direction of the operation member,
The lateral movement of the can body rotatably supported on the base via the can body overturning mechanism and the can body supporting means is controlled by the rotation amount of the operating member,
It can be controlled to correspond to the rotation speed and the rotation direction. Therefore, the operator can easily adjust the overturning amount, the overturning speed, and the overturning direction of the can body by operating the operation member to finely adjust the overturning angle of the can body or to gently stop the overturning operation. Can be done.

As shown in FIG. 3, a disk-shaped operation knob 30 rotatably provided on the housing 28 via a bearing 29 and rotating in forward and reverse directions by a manual operation, and an input shaft connected to the operation knob 30 via a coupling 31. Two-phase detection pulse signals p1 and p2 that are coaxially connected, have a pulse number according to the amount of rotation of the operation knob 30 and a pulse period according to the rotation speed, and have a forward / reverse direction.
Rotary encoder 3 as a signal generation circuit for outputting
2 and DC / which amplifies the levels of the two-phase detection pulse signals p1 and p2 output from the rotary encoder 32 and outputs them as the forward rotation pulse signal P1 and the reverse rotation pulse signal P2.
It comprises a DC converter 33 and a motor drive circuit 34 which outputs a forward / reverse drive signal S to the servomotor 22 based on the forward rotation pulse signal P1 and the reverse rotation pulse signal P2 from the DC / DC converter 33.

The two-phase detection pulse signals p1 and p2 output from the rotary encoder 32 are output with a phase difference of 90 degrees from each other. For example, when the operation knob 30 rotates in the positive direction, the detection pulse signal p1 is output. Is output,
When rotating in the opposite direction, the detection pulse signal p2 is output. Therefore, the DC / DC converter 33 has a function of amplifying the levels of the detection pulse signals p1 and p2, and the phase difference between the two-phase detection pulse signals p1 and p2 output from the rotary encoder 32. It plays the role of determining the rotation direction.

In this case, for example, when the operation knob 30 is rotated in the forward direction, the rotary encoder 32 outputs the detection pulse signal p1 as shown in FIG. 4, and the DC / DC converter 33 outputs the detection pulse signal p1 based on the detection pulse signal p1. It is determined that the operation knob 30 is rotating normally, and the normal rotation pulse signal P1 obtained by amplifying the level of the detection pulse signal p1 is output. Here, the rotary encoder 32 is the operation knob 3
The number set during one rotation of 0 (for example, 2000
The number of pulses of the forward rotation pulse signal P1 corresponds to the rotation amount of the operation knob 30, and the pulse period T
1, T2, etc. correspond to the rotation speed of the operation knob 30. Then, the motor drive circuit 34 outputs the normal rotation drive signal S to the servomotor 22 based on the normal rotation pulse signal P1 from the DC / DC converter 33. For example, only when the normal rotation pulse signal P1 is at the ON level, the servo is performed. Motor 2
2 is operated intermittently to control its rotation amount, rotation speed and rotation direction (forward direction).

Therefore, the lateral movement operation of the drum can D by the lateral body overturning mechanism 16 using the servomotor 22 as a drive source changes at any time following changes in the rotation amount, the rotation speed and the rotation direction of the operation knob 30, and the subdivision work is performed. The operator performing the operation can arbitrarily change the lateral roll amount, lateral roll speed, and lateral roll direction of the drum can D by operating the operation knob 30.

The can body overturning device according to the present embodiment has the above-described structure, and a case of performing a subdivision work using this can body overturning device will be described below.

First, the semi-circular metal fitting 1 of the can body supporting means 11
The outer peripheral portion of the drum can D is gripped by 4 and the drum can D is fixed in a positioned state by the can body fixing member 15. Then, the operating lever 25 of the elevating / lowering operation control unit 24 is operated to the upward side to extend the rod 7B of the hydraulic cylinder 7, thereby raising the drum can D to a desired position via the elevating member 5 and the can body supporting means 11. Then, press the base 1,
The drum can D is conveyed to the vicinity of the subdivision container 36 placed on the weighing machine 35.

In this state, when the operation knob 30 of the rollover motion control section 27 is rotated in the forward direction, the rotary encoder 3
2 outputs the two-phase detection pulse signals p1 and p2 having the number of pulses corresponding to the rotation amount of the operation knob 30, and the respective pulses forming the respective detection pulse signals p1 and p2 have a rotational speed of the operation knob 30. When the rotation speed is slow, the pulse is output continuously with a long pulse period, and when the rotation speed is fast, the pulse is output continuously with a short pulse period. Then, the DC / DC converter 3
Reference numeral 3 identifies the rotation direction (normal rotation direction) of the operation knob 30 based on the phase difference between the detection pulse signals p1 and p2 output from the rotary encoder 32, and detects the detection pulse signal p1 indicating the normal rotation. The forward rotation pulse signal P1 whose level has been amplified is output to the motor drive circuit 34. As a result, the motor drive circuit 34 causes the DC / DC converter 33 to
The normal rotation drive signal S based on the normal rotation pulse signal P1 from the servo motor 22 is output to the servomotor 22, and the servomotor 22 operates only during the period when the normal rotation pulse signal P1 is at the ON level to intermittently move the can body overturning mechanism 16. Drive. As a result, the can body supporting means 11 rotates about the support shaft 12 with respect to the base 1, and the drum can D supported by the can body supporting means 11 rolls over from the initial position indicated by the solid line to the lateral direction indicated by the chain double-dashed line. Roll over to the position.

As described above, when the operator rotates the operation knob 30 in the forward direction, the drum can D is overturned with the amount of overturn corresponding to the amount of rotation of the operation knob 30 and the overturn direction corresponding to the direction of rotation. At this time, the roll speed of the drum can D can be arbitrarily adjusted by changing the rotation speed of the operation knob 30.

Therefore, for example, in the initial stage of the overturning operation, the operation knob 30 is swiftly rotated to rapidly overturn the drum can D to a position where the contents start to be discharged toward the subdivision container 36, and thereafter, the weighing machine 35. By gently rotating the operation knob 30 while observing the display of, the lateral roll amount and lateral roll speed of the drum can D can be finely adjusted. As a result, the contents can be transferred from the drum can D into the subdivision container 36 quickly and accurately, and the workability of the subdivision work can be significantly improved.

After the transfer of the contents from the drum can D to the subdivision container 36 is completed in this way, for example, when the operator rotates the operation knob 30 in the reverse direction, the DC / DC of the overturning operation control unit 27 is turned on. The converter 33 outputs the two-phase detection pulse signal p output from the rotary encoder 32.
The rotation direction (reverse rotation direction) of the operation knob 30 is determined based on the phase difference between 1 and p2, and the reverse rotation pulse signal P is obtained by amplifying the level of the detection pulse signal p2 indicating the reverse rotation.
2 is output to the motor drive circuit 34. Then, the motor drive circuit 34 outputs the reverse rotation drive signal S based on the reverse rotation pulse signal P2 from the DC / DC converter 33 to the servo motor 2
2 to control its operation. As a result, the can body overturning mechanism 16 causes the drum can D to be in a rollover position indicated by a two-dot chain line with a rollover amount corresponding to the rotation amount of the operation knob 30, a rollover direction corresponding to the rotation direction, and a rollover speed corresponding to the rotation speed. To the initial position indicated by the solid line.

As described above, according to this embodiment, by rotating the operation knob 30 which constitutes the overturning operation control unit 27, the overturning direction corresponding to the rotation direction of the operation knob 30 and the overturning corresponding to the rotation amount. Drum can with quantity
Rolls over, and at this time, the roll speed of the drum can D can be arbitrarily adjusted by changing the rotation speed of the operation knob 30. Therefore, by adjusting the overturning amount and overturning speed of the drum can D as needed, the contents can be transferred from the drum can D into the subdivision container 36 quickly and reliably, and, for example, from the drum can D to the subdivision container. Even if a small amount of the content is transferred to 36, the discharge amount of the content transferred to the subdivision container 36 can be finely adjusted.

Further, if the rotation speed of the operation knob 30 is decreased to gradually decrease the overturning speed of the drum can D, the overturning operation of the drum can D is performed when a specified amount of the content is transferred into the subdivision container 36. Even if is stopped, it is possible to reliably prevent the liquid level in the drum can D from shaking due to inertia, and thus it is possible to significantly reduce the error in the amount of the contents transferred into the subdivision container 36.

Further, immediately before the specified amount of the contents transferred into the subdivision container 36 reaches the specified amount, the rotation amount of the operation knob 30 is decreased to finely adjust the amount of overturning of the drum can D to discharge the contents from the drum can D. The flow rate of the contents can be reduced. Therefore, the shaking of the liquid level in the subdivision container 36 can be quickly converged, and the time required for the weighing work of the contents transferred into the subdivision container 36 can be shortened.

In the above-described embodiment, the hydraulic cylinder 7 is arranged between the base 1 and the can body supporting means 11, and the drum can D supported by the can body supporting means 11 by using the hydraulic cylinder 7. However, the present invention is not limited to this, and the drum can may be lifted and lowered by using, for example, a handwheel, and a can body having no drum can lifting mechanism. It can also be applied to rollover devices.

In the above-described embodiment, the case where the DC / DC converter 33, which is a separate circuit, is provided between the rotary encoder 32 and the motor drive circuit 34 has been described as an example. A circuit configuration in which 33 and the motor drive circuit 34 are integrated may be used.

Further, the motor for driving the can body overturning mechanism 16 is not limited to the AC servo motor, but a stepping motor or the like may be used.

[0039]

As described above in detail, according to the present invention, the operation of the motor for driving the can body overturning mechanism is controlled in accordance with the rotation amount, the rotation speed and the rotating direction of the operating member to thereby cause the can body overturning. A lateral movement amount, a lateral rotation speed, and a lateral rotation direction of a can body rotatably supported on a base via a mechanism and a can body supporting means can be adjusted according to the rotation amount, the rotational speed, and the rotation direction of an operating member. With this configuration, by manually operating the operation member arbitrarily, it is possible to easily perform delicate adjustment of the amount of overturning of the can body, gradual stop of the overturning operation, and the like. As a result, the work of transferring the contents filled in the can to the subdivision container can be performed quickly and efficiently while significantly reducing the burden on the operator, and the workability is greatly improved.
