Definitions

  • the invention relates to a rivet press of the type mentioned in the preamble of claim 1.
  • the support to be equipped with the functional element is arranged, with the press open, between the upper and lower tools and the desired attachment point is brought into axial alignment with the tools. This can be done by hand or by means of a mechanically movable frame that holds the carrier to be processed.
  • the functional and fastening elements are automatically brought by a loading device into the associated receiving points of the upper and lower tool before the press, e.g. by actuating a foot switch, is activated for a lifting cycle, where the functional element is attached by means of its fastening element to the desired location on the carrier.
  • the functional element is attached by means of its fastening element to the desired location on the carrier.
  • Vibratory conveyors of this type produce an oriented series of elements which are then loaded and processed element by element in the riveting press with relatively little effort and in a productive manner, but the elements are subject to a not inconsiderable mechanical stress due to the vibrating movement used in their sorting work in the vibratory conveyor.
  • the elements frequently collide against one another and against the guide surfaces of the sorting and guiding means in the vibratory conveyor.
  • the surfaces of the elements are consequently exposed to numerous impact and friction stresses, which can damage the surface. This applies in particular to elements that are chemically refined on the surface to make them look more attractive or to improve the corrosion resistance of the raw material.
  • the invention has recognized that it is possible to get by with the usual surface qualities of the elements and still use the cheap vibratory conveyors if the stress on the elements during their sorting work in the vibratory conveyor is limited to the necessary minimum.
  • the invention has found that the elements are brought up by the vibratory conveyor many times faster than are processed in the riveting press.
  • a switch arranged in the power supply of the vibratory feeder can always be held in its switch-on position by a certain minimum number of operations of the riveting press per unit of time.
  • the vibratory conveyor always re-sorts new elements when the riveting press is actuated in a certain minimum rhythm.
  • the feeding speed of sorted elements which can be controlled by the extent of the vibrating movement, is coordinated in accordance with the normal processing speed of the elements in the riveting press. If, on the other hand, the riveting press is operated at increasingly larger intervals, the invention automatically leads to adapted longer downtimes of the vibrating unit, which is why the vibratory conveyor does not unnecessarily re-sort new elements in such waiting times and exposes them to useless impact stresses. The stress on the elements is therefore kept to a minimum. The elements are treated gently during the conveying process.
  • the means used here are simple, space-saving links that still act like intelligent monitoring devices that would be much more expensive and complicated.
  • the manual control switch is expediently designed as a push button switch.
  • the conveyor pots can be brought into their own operating state when the riveting press with its upper and lower tools is at rest. It is thereby achieved that the newly filled elements in the vibrating conveyor get into the transport rails or up to the upper and lower tools respectively assigned loading devices, of which the elements are individually positioned in the upper or lower tool assigned to them for the riveting work will. If the feed paths are properly filled with the new elements, the manual control switch is turned off again or the key switch is released. Then the vibrating conveyor vibrates and is put back into operation, as described in the main patent, in adaptation to the actuation of the riveting press.
  • the measures of claim 7 enable the elements in the vibratory conveyor to be changed particularly quickly and conveniently. This is always necessary if, instead of a previously used type of element, another type is to be processed on the same press.
  • the vibratory conveyor can be converted into a tilted position in which the previous supply of elements in the feed pot falls out due to gravity.
  • the vibratory conveyor is then returned to its upright position, which is necessary for the operating status of the press.
  • the conveyor pots are filled with the desired new elements and the work of the press can begin again.
  • This tilting of the vibratory conveyor can be carried out particularly easily by the measure of claim 8, wherein the upright position of the vibratory conveyor can be achieved precisely and quickly by appropriate stops between the base and mounting plate.
  • the adjusting means Via such actuators, e.g. an adjusting screw, the distance between the two plates is set so that the output of the elements from the vibratory conveyor is precisely aligned with the transport rails or the upper or lower tool of the press.
  • the transport rail can namely, as proposed in claim 11, form a component firmly connected to the feed pot of the vibratory conveyor, where the elements are also moved in the transport rails due to the vibrating movement. In this case, the transport rails can even rise somewhat up to the loading devices of the two tools.
  • the attachment of the carrier to the machine frame also results in a large space saving.
  • a pneumatic drive for the press is cheap. It is recommended, according to claim 12, to use this pneumatic drive at the same time to control the drive of the jogger depending on the operation of the riveting press according to the main patent.
  • the components used such as bypass, non-return valve and PE converter, are simple components that are characterized by their reliable operation. This enables all controls and monitoring of the riveting process to be carried out pneumatically via a uniform pneumatic energy source.
  • An electric drive is only required for the vibratory feeder vibrating mechanism if the usual devices on the market are used for this.
  • a pneumatic drive could also be used for the vibratory conveyor.
  • the riveting press 10 comprises a two-part upper tool 11 according to FIG. 3, which is moved by a pneumatic lifting drive 12 according to FIGS. 1 and 2, and also a two-part lower tool 13.
  • a pneumatic lifting drive 12 instead of the pneumatic operating mode shown, an electrical lifting drive 12 could also be used, which but is not shown in more detail.
  • One part of the upper tool 11 consists of an upper punch 15 which can be actuated up and down in the direction of the arrow 14, while the other part comprises a pair of pliers 16 with two holding claws which position a functional element, for example a push-button part, between them.
  • the pliers 16 are fastened via a lifting head 18 to a control rod 19, which is guided parallel to the upper punch 15 and can be moved in the direction of the arrow 20 in FIG. 3.
  • This stroke movement 20 could also be timed by the stroke drive ter way to the upper punch 15, but in the present case the downward movement 20 of the control rod 19 is triggered by an operator-operated foot lever, not shown, against the action of a control rod 19 holding it in its top dead center position of FIG. 3, not closer return spring shown.
  • the two-part lower tool 13 initially consists of a stage 21, the top of which acts as a table surface for placing the carrier to be treated, e.g. of a garment. Any textile fabric, plastic sheet or film can be used as a carrier.
  • the stage has a recess 24, in which a stationary lower punch 23 is arranged as the second tool part in alignment with the upper punch 15.
  • the elements complementary to the upper tool 11, namely fastening elements are individually arranged, such as bendable cramps, rollable hollow rivets, compressible rivet shafts or insertable or deformable pins.
  • fasteners are part of the functional element used here in the upper tool, which is why the complementary receiving means, such as perforated disks, caps or the like, are used in the lower tool 13, in which anchoring of the fasteners guided through the carrier from above is used. It would also be possible to perform the assignment of the functional and fastening elements between the upper and lower tools 11, 13 in the reverse manner.
  • the description according to the invention then applies mutatis mutandis.
  • the fasteners used here are usually "self-piercing", i.e. they make their own way through the material of the carrier during the riveting.
  • FIG. 1 and 3 show the idle state of the riveting press, where the two tools 11, 13 are in their top dead center position. Between the holding claws of the pliers 16 there is a receiving nest 25 which, like the mentioned cutout 24 in the lower tool 13, is then aligned with the feed channel of an upper or lower loading device 68, 69, which in the front view of FIG. 3 is behind these tools 11, 13 lies.
  • These loading devices comprise a slide, not shown in more detail, which transfers a single element, which reaches the feed channel there, piece by piece to the recess 24 or the receiving nest 25. There is therefore an automatic loading process of the functional and fastening elements.
  • Such elements are fed to the two loading devices 68, 69 via transport rails 26, 27 which, in the case of FIG. 3, form a fixed structural unit with an oscillating conveyor 32 or 32 '.
  • a vibratory conveyor 32, 32 ' consists of a storage container 28, 29, in which a certain type of functional or fastening elements is filled. It would also be conceivable to use 10 different types of such elements for processing in the press. In this case, a corresponding number of independent vibratory conveyors 32, 32 'is used for each element type, where the elements are fed in aligned form via transport rails 26, 27 and controllable gates to a busbar.
  • the selected element is guided from the various transport rails 26, 27 into the busbar, from where it is brought into the associated loading device 68, 69. Because of the matching structure, it is sufficient to describe one of these vibratory conveyors 32, which then applies mutatis mutandis to all the others.
  • the vibratory conveyor 32 has a pot-shaped container 28, which is connected as a so-called “conveying pot” to a vibrating unit 35 by means of elastic members.
  • the elements are poured into the conveyor pot 28 through the pot opening 34.
  • a spiral sorting track 33 which is equipped with various guide surfaces and internals, goes up from the bottom of the pot along the inner side wall.
  • the vibrating mechanism 35 is driven here by an electric motor located there, the power supply 36 of which is shown in more detail in FIG. 1.
  • the conveying pot 28, as indicated by the arrow 37 in FIG. 3 is set in vibration, as a result of which a movement impulse is exerted on the elements located therein.
  • the width of the sorting track 33 is dimensioned such that the elements only go up one by one in a row. An aligned, individual element therefore appears at the upper end 38 of the web.
  • the associated transport rail 26 is firmly connected to the conveyor pot 28.
  • the aligned elements are brought up to the aforementioned aligned loading device 68.
  • the transport rail 26 could be a body separate from the vibratory conveyor 32, where the elements can slide down to the loading device 68 by gravity. In the present case, they are also moved through the transport rail 26 by the movements emanating from the vibratory conveyor 32, which is why this could be arranged horizontally and even slightly rising towards the loading device 68.
  • an electrical switch 48 which in the present case is part of a PE converter 50, the construction of which is shown in FIG. 5 is described in more detail.
  • a parallel branch 44 is connected to the line 41 and bridges the electrical switch 48.
  • a manual control switch 46 is arranged, which here consists of a push button switch. If the push button switch 46 is actuated, the circuit via the lines 41, 42 is closed, which is why the vibratory feeders 32, 32 'then carry out their working vibrations independently of the operation of the riveting press 10.
  • FIG. 1 shows the idle state of the riveting press 10.
  • the switching element of the switch 48 is brought into the switch-off position shown in FIG. 1 by a return spring 61.
  • the operation of the vibratory conveyor 32, 32 ' is consequently only possible by the aforementioned manual actuation of the key switch 46.
  • the top dead center position of the tools is present, as can be seen from the position of the upper punch 15 shown in FIG. 1 indicated by the upward arrow 14 '.
  • the pneumatic stroke drive 12 comprises a cylinder 17 with a piston 52 displaceable therein, which is connected to the upper punch 15 via a piston rod 56.
  • the following pneumatic circuit 70 is present:
  • Compressed air is supplied from a compressed air connection (not shown in more detail) via the supply line 71 to a pulse valve 72 which can be converted into two switching positions, where it reaches one output line 74 via the one valve channel 73. From the output line 74, the compressed air passes through a check valve 75 to the rod-side end of the cylinder 17, where a rod-side pressure 51 keeps the piston 52 pressed into its upper position.
  • the valve body 76 of this check valve 75 indicated by a ball, is in an upper position closing a ventilation opening 77, to which a silencer 78 is connected.
  • the other piston-side compressed air line 53 ′ located on the cylinder 17 is connected via a similar check valve 75 ′ to a line 79 leading to a distributor 80. In the working position of FIG. 1, however, the associated valve body 76 'closes this line 79 and keeps the associated ventilation opening 77' open to the silencer 78 '.
  • a second output line 74 'of the pulse valve 72 is initially connected to the line 7 in the distributor 80, which leads via a second valve channel 73' to a ventilation opening 82 equipped with a silencer 81.
  • a control line 83 is also connected to the distributor 80, which is why it is only shown in dashed lines in the diagram of FIG. 1. This leads to a pressure switching valve, not shown in any more detail, which is kept depressurized in any case via the silencer 81 in this working position. In this rest position of the riveting press 10, the two vibrating conveyors 32, 32 'rest because of the opened electrical switch 48.
  • the switching position of the pulse valve 72 which is responsible for this, is generated and secured by exerting pressure on the associated valve body via a further one indicated by a broken line in FIG. 1 Control line 84, while another control line 84 ′ acting on the opposite end of the valve body is kept depressurized.
  • the working position of the riveting press 10 shown in FIG. 2 is brought about in that the control line 84 is now vented, while pressure is applied to the other control line 84 'via a control valve, which presses the pulse valve into the second switching position 72' shown in FIG. 2. convicted and held.
  • the aforementioned supply line 71 leads the compressed air via a valve channel 85 to the second output line 74 ′, where it is initially passed on to the compressed air line 79 via the distributor 80.
  • the upper punch 15 strikes the element located in the pliers 16.
  • the pliers 16 have previously been pressed by the already mentioned actuation of a foot lever against the carrier lying on the mentioned stage 21 of the lower tool 13 and have moved the stage 21 downwards against a spring holding them in the upper position shown in FIG. 3, whereby the element there, for example a fastener for the push button, captured by the lower stamp 23 and is brought against the underside of the carrier web.
  • the upper punch 15 now carries out the riveting work, as a result of which the functional element located on one side of the carrier is connected to the fastening element located on the opposite side of the carrier.
  • a pneumatic stub 67 is connected to the distributor 80, in which a throttle 57 is initially connected.
  • the throttle 57 is, however, as shown in FIG. 2, bypassed pneumatically by a bypass 55, wherein a check valve 54 is connected in this bypass 55, which releases the bypass 55 to a pressure chamber 58 located behind the throttle 57 when the branch line 67 is pressurized
  • a check valve 54 is connected in this bypass 55, which releases the bypass 55 to a pressure chamber 58 located behind the throttle 57 when the branch line 67 is pressurized
  • compressed air is quickly transferred to the other side of the throttle 57 via the opened bypass 55 and can act on the PE converter 50 mentioned.
  • the switching element of the electrical switch 48 is transferred from the switch-off position of FIG. 1 to the switch-on position shown in FIG. 2.
  • Such a drive of the vibratory conveyor 32, 32 ' is available as long as the riveting press 10 is operated in the usual working rhythm. This depends on the time interval at which the foot pedal mentioned is actuated by the operator. If, by reversing the two lines 84, 84 ', the pulse valve is moved back into its switch position 72 shown in FIG. 1 and the upper dead center position of the upper punch 15 shown there is brought about, the switch 48 does not immediately go into the corresponding switch-off position of FIG. 1, but remains switched on, according to FIG. 2. This is because the amount of air accumulated in the pressure chamber 58 cannot flow away immediately, although, as shown in FIG.
  • the throttle 57 is adjustable, which is why the minimum number of actuations of the rivet press per unit of time at which the sensor element 45 only brings the switch 48 into its switched-off position can be set.
  • the sensing element 45 thus monitors the cycle sequence of the operations of the riveting press 10. If there is a delay in the actuation of the foot switch that exceeds the usual level, the drive of the vibratory feeders 32, 32 'is interrupted and the elements are not unnecessarily subject to wear in the associated ones Funding pots 28 and 29 exposed.
  • FIG. 5 shows the structure of the press in the area of the PE converter 50 in a semi-schematic manner.
  • the pressure chamber 58 mentioned is located in front of a membrane 59 which is held in the illustrated starting position by a spring 61 which is supported at one end in the housing.
  • the other end of the support spring 61 is supported on a disk 62 stiffening the membrane 59, whereby the membrane 59 is held pressed against the inner shoulders 63 of the housing.
  • a plunger 64 points in the direction of movement of the membrane and bears against the disk 62 with its upper end. Under the action of the pressure medium in the pressure chamber 58, the membrane 59 is finally bent downward against the force of the return spring 61 and takes the plunger 64 with it.
  • the handle 65 of the electrical switch 48 is located in axial alignment with the plunger 64, the contact member of which is then closed according to FIG. 2 and connects the two contact connections 66 shown in FIG. 5. In this way, the pneumatic signal occurring in the pressure chamber 58 is converted into an electrical switching pulse.
  • a frame 86 of the rivet press 10 which can be formed by a smooth column, an angle piece with its one leg 87 is attached via a first clamping connection 89, while on the other angle leg 88, the associated vibratory conveyor 82 is attached.
  • the invention enables a quick exchange.
  • Locking members could be provided, for example between the two in the closed position of FIG 3 plates 90, 93, which secure the normal upright position of the vibratory conveyor 32 of Fig. 3.
  • the mounting plate moves into its tilting position 93 "shown in Fig. 4.
  • the elements located inside the pot can fall out due to the action of gravity.
  • the vibratory conveyor is then moved back to its upright position 32 from FIG. 3, whereupon a new filling of another type of elements can be poured into the conveyor pot 28. 4, the transport rail connected to the conveyor pot 28 is also pivoted and reaches its shown emptying position 26 ". The elements of the preceding type located here also consequently fall out of their own accord.
  • the transport rail 26 is therefore empty and can immediately be filled with the new type of elements. This is done, as has already been described above, by actuating the pushbutton switch 46, as a result of which the elements can be brought up to the loading device 68 or 69 without a working stroke of the riveting press 10. The riveting press 10 is thus quickly ready for operation again for the new type of elements.
  • the riveting press 10 can also bring about its working stroke by means of electrical drive means, which then take the place of the pneumatic operation.
  • a corresponding sensing element 45 is then used, which acts on an analog switch 48 in the opening direction of FIG. 1, provided that the riveting press 10 is not actuated again within a certain minimum period.
  • Such a sensing element therefore counts the number of switch-on operations of a corresponding electric lifting drive for the upper tool 11 per unit of time.
