Abstract

A universal gravity storage container for cylindrical parts, especially flange-shaped parts, intended primarily for the input part of a robotized workplace, has fixed side walls attached to an inclined beam on one side and sliding side walls opposite them, the movement of which is controlled by a common control element, while guide rails are attached to the inside of these side walls. The upper part of the beam is equipped with cassettes in several places, into which replaceable shaped inserts are inserted. Grooves are formed in these shaped inserts, in which the lower skid rails are placed. A dispenser is located in front of the removal center in the output part of the storage container, which is functionally connected to the robot control system.

BACKGROUND OF THE INVENTION The present invention relates to a universal gravity reservoir of cylindrical components, in particular flange-shaped components, intended in particular for the entrance part of a robotized workroom.

So far, the known cylindrical component magazine for the entrance section of the robotized workstation works on the principle of the chain magazine. It consists of two stands, which are connected by partitions and an adjustable frame. A prismatic conduit is screwed onto the frame, into which cylindrical parts are inserted, which are pushed to the sleeve by means of a chain operated rod, from where the industrial robot chooses them. The disadvantage of this container is the change of the component axis when changing the diameter of the component. From this point, the vertical ro-shoe, which must be adjusted so that the axis of the part coincides with the gripper axis, must be adjusted. The rebuilding must always be done when switching to a new component, which causes considerable downtime. The disadvantage of such a conveyor is also that it does not conform to the flange-shaped component and also to the cylindrical components of the various sections.

These drawbacks are eliminated by the universal gravity cylinder cylindrical stack consisting of a beam which is supported on the inclined plane by adjustable adjusters according to the invention, which consists in the fact that the beam is provided with several crossbars spaced at equal intervals on its length wherein each of the cross members is provided on one side with a fixed sidewall and on the other with a sliding sidewall controlled by a sliding mechanism. Individual sliding mechanisms are synchronized with each other. Guide rails are attached to the inner surfaces of fixed sidewalls and sliding sidewalls. Cartridges are mounted on top of each other at the top of the beam, in which replaceable insert inserts are inserted, each of which is provided with grooves in which the lower housing strips are housed. A component dispenser is provided upstream of the removal center in the exit portion of the container and is operatively connected to the robot control system. An advantage of the universal gravity stack of the cylindrical components according to the invention is that by replacing the replaceable molded components it is possible to use cylindrical parts of different diameters and also cylindrical flange-shaped parts of different diameters, with the component axis remaining unchanged, a vertical carobot that is aligned so that the axis of the part coincides with the gripper axis. It indicates that it is not necessary to convert the vertical robot unit during the transition of the machining of another component, thus saving the time needed for this adjustment. Also, the advantage of this container is that, with respect to the sliding sides, which are part of the transportable frog, it is possible to use cylindrical parts and also cylindrical flange-like parts in a relatively wide range. accident during frequent conversions of automatic technological work.

In the accompanying drawing, an example of an embodiment of a universal gravity reservoir of cylindrical parts of the invention is shown, wherein in Fig. 1 this reservoir is shown in a front view and in Fig. 2 in a plane A - A.

The universal gravity reservoir in and around the components of the invention consists of a carrier 2 which is supported in the inclined plane by displaceable stands 1. The beam 2 is provided with a plurality of crossbars 18 disposed at equal intervals on its length. Each cross member 18 is provided on one side with a fixed sidewall 8 and with a sliding sidewall 9 on the other side. Each sliding sidewall 9 is controlled by a sliding mechanism which is formed by a control screw 11 which is rotatably and non-slidably supported in the fixed sidewall 8 and also in the bracket 17 fixedly connected to the crossbar 18. The sliding sidewall 9 is provided with a continuous threaded bore through which the control screw 11 passes.

One end of the control screw 11 is provided with a chevron on which the plug 16 is pushed. The other end of the control screw 11 protrudes beyond the fixed side 8 and has a double sprocket 15 on it. the screws 11 are mechanically synchronized with each other. In order to stabilize each sliding sidewall 9, it is further provided with a continuous opening through which the sliding sidewall 9 is moved by a slidably mounted guide rod 14 which is clamped at one end in a fixed sidewall 8 and a second cone is fixedly fixed in the console 17. At the top of the beam 2, cassettes 5 in which replaceable mold inserts 6 are inserted are provided in several places. Each replaceable molding 6 has longitudinal grooves in which the lower slide rails 7 are inserted. the side guide rails 10 are attached to the inner surfaces of the fixed sidewall 8 and the sliding sidewall 9. The cylindrical flange portion 13 is supported by its lower base rails 7 and the side guide rails 10 on its side. is created by a collection prize 3 for the robot tentacle. A dispenser 12 of cylindrical components 13 is attached to the container in front of the collection center 3. The height adjustment of the axis of the spherical component 13 with the gripper axis is determined by the design of the replaceable sleeves 6. At each change of the machined cylindrical component 13

5, 254034, it is necessary to replace the replaceable shim 6 in the sheath 5 and to slide the grooves of the bottom of the shear bar 7. By turning the shank 16 from one place, the required width of the shifting sidewalls 9 is adjusted so that the cylindrical component 13 can move between the side guiding bars 10. The chain transfer through the double chain sprocket 15 ensures uniform displacement of all the sliding sidewalls 9. The container thus set is filled with cylindrical parts 13, whereby it is ready to start the automatic technological operation in the automatic cycle. The desired displacement components 13 in the reservoir are adjusted by varying the inclination of the reservoir, which is accomplished by the height adjustment of the displaceable columns 1. The aim of the dispenser 12 is to catch the cylindrical component 13 in front of the withdrawal center 3 and enter it into the withdrawal center 3 only after removal of the previous cylindrical component 13 The dispenser 12 is electrically coupled to the robot control system. The sensor housed in the withdrawal center 3 gives the signaling system the presence of the cylindrical component 13. In the case of occupancy of the withdrawal center 3 by the cylindrical component 13, the control system commands the gripper to grip the component and refine the machine tool. During the machining device, the dosing device 12 re-dispenses one cylindrical component 13 of the diving center 3, whereby the workpiece is prepared for the next cycle. This cycle is repeated until the hopper is empty. After emptying the hopper or during machining, replenish the hopper. OBJECT 1.
