Definitions

• the invention relates to a fat handling system for supplying fat metering devices, which is provided with a plurality of portable fat storage containers and a container pump.
• So-called container or barrel pumps are usually used to supply grease dosing devices to semi or fully automatic assembly facilities. These pumps convey the grease from the original containers, which have a content between 10 and 200 liters, via lines into the metering devices.
• the use of such tank pumps directly at the workplace has various disadvantages, so the tank pumps have to be positioned on the floor in such a way that access for changing the tanks is possible. The space requirement is therefore large, the cable routes are long. Changing the grease container is time-consuming and requires trained personnel. A carryover or contamination of the grease by opening the grease container and moving the grease follower cover cannot be ruled out. If synthetic fats are stored in large containers for a longer period of time - which is very often the case with small doses - the solid components of the fat can separate from the carrier oil.
• the invention has for its object to provide a grease handling system that makes the arrangement of drum pumps in the area of assembly machines unnecessary.
• the filling and removal stations each having a locking coupling for the Grease and are provided with a locking coupling for compressed air and the plurality of fat storage containers are each provided with a grease nipple which cooperates with them and leads to a grease space and a compressed air nipple which leads to a compressed air space.
• the fat space and the compressed air space are separated from one another by a movable wall.
• the wall can be formed by a membrane or a bellows, but a configuration is preferred in which the fat storage containers consist of a cylindrical tube, a lower blind flange closing the tube down, an upper blind flange closing the tube upwards and supporting the nipple with one of the nipples communicating, in the blind flanges centrally mounted hollow shaft and one on the hollow shaft guided, sealed against this and against the inner wall of the tube, forming the movable wall piston, the other of the nipple communicating with the upper space and the lower end of the hollow shaft with the lower space.
• the upper room should be the compressed air room and the lower room the fat room.
• the piston be provided with a magnetic ring, which allows the filling level to be queried with a magnetic sensor.
• FIG. 2 is a schematic view of the fat storage container in a side view with the handle pointing upward, a partial side view with a handle folded down and a top view,
• FIG 3 shows the fat storage container used in a filling and removal station in a sectional view or in a front view, the filling and removal station being connected to a fat metering device, and
• Fig. 4 is an illustration of one of the filling and removal stations, which is connected to a container pump.
• the fat storage container 12 shown in FIG. 1 is formed by a cylindrical tube 32, an upper blind flange 36 and a lower blind flange 34 and a centrally arranged hollow shaft 38, on which a piston 30 is mounted so as to be longitudinally movable.
• the piston 30 is provided with seals in the area of the contact surfaces between the piston 30 and the pipe 32 and between the piston 30 and the hollow shaft 38.
• the piston 30 separates an upper space 26 loaded with compressed air from a lower space 22 filled with grease.
• a locking nipple 24 of a quick-release coupling which closes on both sides, is mounted in the upper blind flange 36 and connects the systems carrying grease (i.e. the container pump or the metering device) with the grease chamber located below the piston 30.
• a further locking nipple 28 of a quick-action coupling that shuts off on both sides on the upper blind flange 36 serves to connect the compressed air space 26 above the piston 30 to a controllable compressed air system.
• the hollow shaft 38 is mounted in the lower blind flange 34 so that the bore of the shaft 38 has a connection to the grease chamber 22 below the piston 30.
• a bore 42 which is closed by a screw plug 44, is used when the piston 30 is lowered to vent the grease system, which is particularly necessary for the initial filling.
• FIG. 2 shows that a carrying handle 46 is arranged on the upper flange 36, which handle can be folded over by 90 ° after a brief lifting against the force of a spring 48 in the direction of the container axis.
• a U-shaped plate 50 (FIG. 1) is provided between the carrying bars of the handle 46 and protects the closure nipples 24, 28 from dirt when the container is inactive.
• an exchangeable plate 52 On the front side of the upper flange 36 there is an exchangeable plate 52 on which the material designation for the grease and a code number encoded in the number sequence 1-8 can be inserted.
• a steel bracket 54 is bolted to the back of the upper flange 36 which can be set in one of the eight positions in accordance with the code number of the material.
• the piston 30 is provided with a magnetic ring 40 (FIG. 1) which can be queried by external magnetic sensors in order to enable a fill level control.
• the filling and removal stations 16 consist of a frame 56, preferably made of sheet steel.
• a receptacle 58 for the fat storage container is fastened to the lower base of the frame.
• a coupling device 60 is provided on the upper part of the frame 16, in which a grease quick-release coupling 18 and a dry air quick-release coupling 20 are arranged.
• a compressed air cylinder 62 attached to the coupling device 60 serves for the automatic locking and unlocking of the quick-release couplings 18, 20.
• the coupling device 60 is firmly connected to the frame 56 via a compressed air cylinder 64.
• the entire electro-pneumatic control system which controls the loading and unloading of the fat storage container 12, is integrated in the frame 56.
• Two control buttons 68, 70 are used to trigger the automatic process for coupling the systems carrying grease or compressed air to the grease storage container 12 or to separate both.
• a precision pressure regulator 72 allows adjustment of the pneumatic delivery pressure for unloading the fat storage container 12 or a constant counter pressure when loading the fat storage container 12.
• An interrogation sensor 74 checks the exact position of the fat storage container 12 in the frame 56, an interrogation sensor 76 the correct allocation of the fat storage container to the fat metering device 10 or to the container pump 14, a query sensor 78 for querying the highest filling level in the fat storage container when using the device with the container pump 14 and query sensors 80 for querying the discharge state in the fat storage container 12 when using the device with the fat metering device.
• the sensor 74 reports the correct position of the fat storage container 12. 1.1.2 The sensor 76 reports the code match between the fat storage container 12 and the respective filling station 16, the control button 68 flashes.
• the sensor 78 signals the end of the filling process, the control button 70 flashes.
• the control button 70 flashes and signals the impending discharge of the container.
• the sensor 74 reports the correct positioning of the fat storage container 12.
• the sensor 76 reports the code correspondence between the fat reservoir 12 and the filling removal station 16, the operating button 68 flashes.
• the fat storage container 12 is automatically coupled to the fat and compressed air system.
• the device for emptying the fat storage containers 12 require little space, they can be placed in the immediate vicinity of the fat metering devices 10.
• the cable routes are short, reserve containers for changing can be stored in stock.
• the pre-pressure of the fat to the fat metering device is absolutely constant.
• the coding system prevents the use of incorrect greases in the workplace.
