Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention draws out a viscous fluid from a bellows type cartridge containing a viscous fluid such as grease according to a predetermined control from a control unit by a plunger pump linked with a motor driven by a dry cell, and a small amount at regular intervals. One by one, it relates to a viscous fluid supply pump that discharges directly to the lubrication points of industrial equipment.

[0002]

[Prior art and its problems]

 In the conventional viscous fluid supply pump of the type driven by dry batteries, the bellows type cartridge and the drive system including the dry batteries are not integrated but provided separately in separate storage cases. Therefore, there are the following problems. (1) When replacing the cartridge, it is easy to forget to replace the dry battery, which causes discharge failure due to exhaustion of the dry battery, and problems such as bearing seizure are likely to occur. (2) The replacement work of the cartridge and the dry battery was troublesome because it was necessary to attach and detach both storage cases. (3) The viscous fluid supply pump is often installed in a narrow place, but if it is installed in a narrow place and the mounting direction of the cartridge and the mounting direction of the dry cell are different, replacement work is not necessary. It was difficult. In order to eliminate such a difficulty, it had to be installed in a wide area, and there were restrictions on the installation location.

The control board 5 controls the motor 3 to operate every 4 hours for 3 seconds when the activation timer is set to 4 hours and the operation timer is set to 3 seconds. The amount of viscous fluid in the cartridge 2 is set so that it will almost disappear when the life of the dry battery 41 is exhausted.

FIG. 10 is a longitudinal sectional view showing the cover 6, and FIG. 11 is a view taken in the direction of arrow XI in FIG. The cover 6 covers the cartridge 2, the motor 3, the holder 4, the control board 5, and the like, and is attached to the pump body 1. Inward projections 61 are formed on the lower edge of the cover 6 at three locations at equal intervals in the circumferential direction. On the other hand, on the peripheral surface of the main body 11 of the pump body 1, as shown in FIG. 4, a groove 62 into which the protrusion 61 can be fitted is continuously formed in the circumferential direction. Reference numeral 63 is a notch formed by notching a part of the groove 62 so as to open upward, and is formed at three locations at equal intervals in the circumferential direction. The cover 6 is attached to the main body 11 by fitting the protrusion 61 from the notch 63 into the groove 62 and rotating the cover to displace the protrusion 61 from the notch 63, and vice versa. It is designed to be removed by operation. That is, the cover 6 is vertically detachable from the pump body 1. Reference numeral 64 denotes a stopper projection formed in the groove 62 for stopping the rotation of the cover 6 along the groove 62.

As shown in FIG. 1, a bottomed cylindrical spring holder 71 is placed on the upper surface of the cartridge 2, and a spring 7 is provided in the spring holder 71 so as to cover the upper surface of the cover 6 and the cartridge. It is housed so as to urge them in opposite directions.

Next, the operation of the viscous fluid supply pump having the above configuration will be described. When the motor 3 operates under the control of the control board 5 in the state shown in FIG. 1, the plunger 31 reciprocates via the cam mechanism 33 and the crank lever 34, and the viscous fluid in the cartridge 2 exits the hole 21 and the hole 121. Through the passage 122, the piston chamber 123, and the passage 124. At this time, the check valve 125 prevents the backflow of the viscous fluid. Further, since the cartridge 2 is always urged downward by the spring 7 provided between the cartridge 2 and the cover 6, the viscous fluid in the cartridge 2 is always pushed out from the outlet 21. Suction of the viscous fluid by the plunger 31 is promoted, and the viscous fluid is discharged well. Further, since the guide cylinder 21 prevents the cartridge 2 from bending, the viscous fluid can be discharged well from this point as well. Although the viscous fluid supply pump as a whole vibrates due to the operation of the motor 3, the projection 221 of the guide cylinder 22 is fitted into the groove 222, and the cover 6 is fitted with the projection 61 into the groove 62. Sometimes it does not come off from the pump body 1. In particular, since the cover 6 is biased upward by the spring 7, the projection 61 is strongly hooked to the upper edge of the groove 62, and is hard to come off.

In the viscous fluid supply pump configured as described above, the replacement work of the cartridge 2 and the dry battery 41 is performed as follows. First, the cover 6 is rotated so that the protrusion 61 is located at the position of the cutout 63, and is pulled up to be removed from the main body 11 of the pump body 1. Next, when removing the cartridge 2, first, the guide tube 22 is rotated so that the projection 221 is located at the notch 223, and is pulled upward to remove it from the projection 12 of the pump body 1. Then, the cartridge 2 is rotated, the outlet 21 is pulled out from the hole 121, and is pulled up. When the dry battery 41 is removed, the holder 4 is pulled upward while resisting the pressing force of the pressing plate 44 until the upright portion 45a of the mounting plate 45 comes out of the gap 44b, and the holder 4 is opened to remove the dry battery 41. Take out. The attachment of a new cartridge 2 or dry battery 41 may be carried out in the reverse order of the above operation.

Since both the cartridge 2 and the dry battery 41 are provided on the upper surface of the pump body 1 so as to be covered with the cover 6, they can be exposed by simply removing the cover 6. Therefore, in the above replacement work, it is hard to forget one of the replacements.

Further, since the cover 6, the guide tube 22, the cartridge 2, and the holder 4 are all attached and detached in the vertical direction, that is, in the same direction, even if the viscous fluid supply pump is installed in a narrow place, the replacement work of them is not required. It will be easy. Also, it can be installed in a small space without any problem.

Since the cover 6 and the guide cylinder 22 are transparent or translucent, each component housed in the cover 6 can be visually observed from the outside. Therefore, not only the amount of the viscous fluid remaining in the cartridge 2 but also the pump function including the drive system such as the plunger 31 can be checked.
