Description

Automatic drum replacement device for grease

The present invention relates to a device for smoothly operating a facility by detecting whether the grease should be supplied according to the amount of grease by a sensor and automatically replacing the grease drum.

In general, grease is supplied to correction lines and rolling lines in order to operate the machine smoothly. Frequent replacement and dissemination of grease drum can reduce work efficiency and cause safety accidents during manual replacement. According to Grease's Grease Supply, a 18-litre pail was manually mounted on a manual grease pump and a manual grease nipple of a manual grease pump was connected to the nipple of a 40-litre grease punk to manually stir the grease to the tank. The nipples were connected and the operator manually stirred to replenish grease to the tank. Since grease needs to go to the site and check the supply time, the wear and damage of the equipment has occurred.

The present invention is made to solve the problems of the prior art as described above, when grease is automatically supplied to the machine to determine the replacement time of the grease in advance to automatically replace the grease drum barrel to extend the life of the machine and to prevent equipment accidents in advance Provided with a grease automatic replacement device that can prevent the bar, the device according to the present invention, by installing an airless pump (Airless) pump to transfer the grease drum barrel to the replacement place automatically by using the forward and backward cylinder by the moving truck and the detection sensor It is configured to transfer and install the grease drum by grasping the replacement time by the bar, and the wheel on which the rail is placed on the rail and the hole in which the grease drum is to be seated is formed, and the bogie is operated to raise and lower the bogie. And a cylinder for opening and closing the rail lifting door, The vehicle is fixed to facilitate the injection of grease, and the rail lifting and lowering door opened and closed by the connecting rod of the cylinder, the cylinder for moving the truck forward and backward, and the grease drum can be detected to indicate whether the replacement time is lower and upper. It consists of an airless pump equipped with a limit sensor installed in the sensor, a sensing bar and an electronic valve that automatically mounts the pump.

The present invention provides a device that automatically replaces the grease drum when grease is supplied, which can extend the life of the machine and prevent the accident in advance by detecting the grease replacement time automatically when grease is automatically fed to the machine. The purpose is to provide.

The grease drum barrel automatic replacement device according to the present invention will be described in detail below with reference to the accompanying drawings illustrating preferred embodiments.

Figure 2 is a side view of the grease drum barrel automatic replacement device according to the present invention, Figure 3 is a plan view of the device shown in Figure 2, Figure 4 is a perspective view showing the state of use of the device of the present invention. In addition, Figures 5 to 8 is a view showing in detail the cart, the door and the side panel, and the connecting rod constituting the device of the present invention. As shown in the figure, the airless pump body 1 is provided with a sensing bar 1d in the middle of the main body as shown in FIG. The position moved adjacent to is indicated by the limit sensor 1f, and the electromagnetic valve 1g is disposed opposite the sensing bar, and is disposed below the airless pump main body 1, and the grease drum 1a is seated. The trolley 2 is provided with a hole 3 to prevent the swing of the upper side, the support plate 3a is located in the lower portion of the hole 3 of the trolley 2 on which the drum cylinder 1a is seated. The support plate is coupled to and supported by a link coupled with a branch rod extending both sides at the middle and the end of the connecting rod 10 connected to the moving cylinder 7.

In addition, as shown in FIG. 5 (a) and FIG. 7, a swivel 8a is installed in the main body of the cylinder 8 to prevent the impact of the cylinder 8 while the bogie 2 is lowered when the replenishment position is mounted. As shown in Figs. 7 and 8, a proximity sensor 2a for monitoring the forward and backward movement of the trolley is arranged on the side of the trolley, and the proximity sensor 2b shows the reversed state. On the side of the vertical movement cylinder (7) is arranged a proximity sensor (7a) for monitoring the movement of the shank, as shown in FIG. 2 and FIG. 4, the rail on which the wheel (5) of the trolley (2) is placed ( A rail raising and lowering 6 for accommodating 9) is provided, and a stopper 4 for preventing the wheel 5 from shaking when the rail is lowered is also provided.

Hereinafter, the operation of the device of the present invention will be described with reference to the operation flowchart shown in FIG.

After mounting the grease drum 1a by the hoist 11 to the hole 3 formed in the trolley | bogie, it operates by AUTO at the side panel 12. FIG. The operation sequence is as follows. When the RUN button is pressed after switching the selector switch to auto on the side panel 12, the cart 2 advances by the forward and backward cylinder 8. Advancement is completed by the proximity sensor 2a provided in the side of a trolley | bogie. The rail elevating door 6 is opened by the elevating cylinder 7 by the advance completion signal, and the wheel of the trolley is landed on the floor to prevent the swing of the grease drum. In response to the falling completion signal from the proximity sensor 7b disposed on the side of the elevating cylinder 7, the electromagnetic valve 1g installed in the airless pump 1 is operated so that the airless pump 1 is lowered to be mounted in operation standby state. do. If the grease drum is empty after the airless pump repeatedly feeds the grease by operating the lever on the cab panel, the sensing bar 1d installed on the main body of the airless pump contacts the lower limit sensor 1e to the airless pump 1. The installed electromagnetic valve 1g is opened and the airless pump 1 is raised.

At this time, the buzzer notifies when the grease is replaced in the cab. When it is detected that the lift is completed by the limit sensor 1e installed in the upper portion, the rail lift door 6 is closed by the lift cylinder 7 in response to the lift completion signal. At this time, since the wheel stopper is formed to prevent rocking of the wheel 5, it naturally rises.

The lifting lowering cylinder 7 is fixed and is raised and lowered by the connecting rod 10. When the trolley 2 is raised, the forward and backward cylinders 8 are reversed by the rising completion signal, and arrival or not at the right position is monitored by the proximity sensor 2b provided on the side of the trolley. When the truck arrives, the empty grease drum is taken out with the hoist 11, and a new drum is installed again to replenish grease. When the trolley 2 is mounted at the replenishment position, the swivel 8a is installed in the cylinder main body in order to fully lower the impact of the forward and backward cylinders 8 so that the cylinders are naturally raised and lowered.

According to the automatic replacement device for the grease supply drum according to the present invention, the grease is automatically detected and notified to the driver so that the grease is smoothly supplied to the facility to prevent the wear and accident of the facility and to reduce the frequent replenishment of the grease. By supplying grease for a long time with one supply, the fatigue of the worker can be reduced due to manual supply, and it is possible to prevent safety accidents when manually supplying with a pair of two people.
