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 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.
  • Such vibratory conveyor produce, although with relatively little effort and productive manner, an oriented series of elements annelementweise d are loaded in the rivet press and processed, but the elements in their sorting work in the oscillating conveyor subject to non-negligible mechanical stress due to the used therein shaking.
  • the elements often collide against each other and against the guiding 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 common surface qualities of the elements and still use the cheap vibratory conveyors, if the stresses on the elements during their sorting work in the vibratory conveyor are limited to the necessary minimum. This is because the invention has found that the elements are brought up by the vibrating conveyor much 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. This ensures in a very simple way that the vibratory conveyor damper then 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.
  • 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 shock loads.
  • 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 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 S chwing- conveyor can be converted into a tilted position in which the existing stock of items in the bowl by gravity fall out.
  • 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 according to claim 9.
  • the distance between the two plates is adjusted by means of such adjusting means, for example an adjusting screw, 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 ll, one firmly with the pot of the Vibrating conveyor connected component form, where the elements are moved due to the shaking movement in the transport rails. 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 means that all controls and monitoring of the riveting process can be carried out pneumatically via a uniform pneumatic energy source.
  • An electric drive is only required for the vibratory conveyor 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 have a functional element, e.g. position a push button part.
  • 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 is movable in the direction of the arrow 20 in FIG. 3.
  • This lifting movement 20 could also start from the lifting drive in a timed manner to the upper punch 15, but in the present case the downward movement 20 of the control rod 19 is triggered by a foot lever, not shown, to be operated by the operator, against the action of the control rod 19 in its top dead center position of Fig. 3 holding, not shown return spring.
  • 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 arranged individually, 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. behind these tools 11, 13.
  • 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 into 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 an 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. Through the pot opening 34, the elements in the Funding pot 28 poured. From the bottom of the pot, a sorting track 33 in spiral form goes up along the inner side wall, which is equipped with various guide surfaces and internals.
  • 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 corresponding transport rail 26 is as already mentioned in continuation of this sort path 33, determined with the ördertopf F 28 is connected.
  • 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 by the transport rail 2'1 due to the movements emanating from the vibrating conveyor 37 moved through, which could be arranged horizontally and even slightly rising to the loading device 68.
  • an electrical switch 48 which in the present case is part of a PE converter 50, the latter Structure is described in more detail in Fig. 5.
  • 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.
  • a second output line 74 'of the pulse valve 72 is first connected to the line 79 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 platform 21 of the lower tool 13 and have moved the platform 21 downwards against a spring holding them in the upper position shown in FIG. 3, whereby the element there, e.g. a fastener for the push button, captured by the lower stamp 23 and 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, a check valve 54 is connected in this bypass 55, which releases the bypass 55 to a pressure chamber 58 behind the throttle 57 when the stub 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 aforementioned PE converter 50.
  • 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.
  • valve Body in the check valve 54 now blocks the bypass 55, as indicated in FIG. 1, which is why the air in the pressure chamber 58 takes some time to flow out through the narrow throttle 57.
  • the components 57, 54, 58 act in conjunction with the PE converter 50 as a sensing element 4F for a certain number of operations of the riveting press 10 per unit of time. Only after a certain time has so much air escaped from the pressure chamber 58 that the return spring 61 can move the switching element in the switch 48 to the off position in FIG. 1. As illustrated by the arrow symbol in FIGS.
  • 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 goes beyond the usual amount, 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 namely a stiffening the membrane 59 from disc 62, whereby the M em- bran 59 against internal shoulders 63 of the housing is pressed is maintained.
  • 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 which has already been mentioned several times, is located in axial alignment with the plunger 64, the contact element of which then ig according to the F. 2, is closed 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 plates 90, 93 located in the folded position of FIG. 3, which secure the normal upright position of the vibratory conveyor 32 of FIG. 3.
  • the mounting plate moves into its tilting position 93 ′′, which can be seen in FIG. 4.
  • the elements located inside the pot can fall out due to the action of gravity.
  • the vibrating conveyor is again strength in its main- position 32 from F. 3 transferred, whereupon a new filling of a different type of elements can be poured into the conveyor pot 28.
  • the transport rail connected to the conveying pot 28 is also pivoted and reaches its shown emptying position 26 ′′.
  • the elements of the previous variety located here also fall out of their own accord.
  • the transport rail 26 is therefore empty and can be filled immediately 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. There is then a corresponding sensing member 45 used which acts on an analog switch in the 4 8 Ausschaltsinne of Fig. 1, 10 is not provided the rivetting press within a certain minimum duration is operated again. 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.
