Definitions
- the present invention relates to a device for feeding flat products to a processing device for printed products.
- a device of this type is disclosed in the older CH patent application No. 03250 / 91-8 with the title "Device for gluing inserts to printed products”.
- This has a belt conveyor which feeds inserts spaced apart from one another to a takeover area. There, the inserts are taken over by a transfer conveyor and conveyed past an adhesive application device and fed to a drum-like processing device for printed products, the inserts being brought to the printed products by means of the transfer conveyor and pressed on for gluing.
- the transfer conveyor has several flat holders with suction heads or controlled grippers for taking over and conveying the inserts.
- the holders are rotatably mounted on pivot levers, which in turn are articulated on a wheel-like, rotatably driven support member.
- Handlebars continue to engage on the brackets, which are also pivotally mounted on the other side of the support member and which are coupled to an epicyclic gear to control the pivoting position.
- the holders are directed approximately tangentially to their orbit and are pivoted in the same direction in the course of about half a turn of the support member by the epicyclic gear to the support member, so that they are now oriented approximately at right angles to their orbit.
- each holder is moved forward in the direction of rotation with respect to the support member in order to bring the insert onto a printing product placed astride a saddle-shaped support of the processing device and press it on. The holder then releases the attached insert and is brought to the takeover area in order to take over an insert.
- Another device for gluing flat products in the printed product is disclosed in DE-A-21 35 303.
- Two application heads equipped with a gripper device are fixedly arranged on an endless, rotating conveyor element.
- the gripper devices serve to remove one product from a magazine and hold it until the application heads are placed on the printed product to which the product is to be glued and which is processed in the same direction and at the same speed as the processing conveyor parallel to the run of the conveyor Conveyor is driven, is transported.
- EP-A-0 312 755 and EP-A-0 305 671 as well as the corresponding US-A-4,982,944 and US-A-4,893,805, a device is known in which printed products by means of a conveyor with successively arranged individually controllable grippers be taken to a takeover area.
- a transfer conveyor has, at regular intervals, take-over grippers fastened to a driven, endless traction element, the movable jaw of which, in the open position, is pivoted laterally away from the associated fixed jaw and in the closed position this is rectified.
- the transfer conveyor is driven in the same direction as the conveying device, the grippers of which are controlled in the opposite direction to the takeover grippers of the transfer conveyor in order to use the latter to grasp the printed products fed in at their trailing edge and to feed them to a winding device, where they are wound onto a winding core.
- the device Due to the wheel-like design of the support member, the device is space-saving and simple in construction. By pivoting the clamps, the products can both be placed on a conveyor belt and introduced into pocket-like receiving parts of the processing device. Furthermore, this device also allows the products to be pressed on in the processing device if the clamps are designed accordingly.
- a particularly simple control of the position of the clips is achieved by the preferred embodiment of the device according to the invention.
- the particularly preferred embodiment of the invention Device according to claim 3 allows the products to be brought to locations of the processing device remote from the support member with a small footprint.
- the preferred embodiment of the clamps according to claim 4 allows in a simple manner the safe takeover of the products in the takeover area at high processing speed and the pressing of the products against a counter bearing of the processing device in the transfer area. This also ensures that products are securely adhered to printed products in a simple manner.
- the preferred embodiment of the device according to claim 5 allows products of different thicknesses to be transported and, in particular, these products to be pressed against a counter bearing without being damaged and without adjustment work being necessary.
- a further, particularly preferred embodiment of the device according to the invention is specified in claim 6. This ensures that the products are held securely even in the transfer area.
- the products are securely adhered to printed products in that the products are applied to the printed product in the area of adhesive application be pressed.
- Fig. 1 shows schematically a device for feeding flat products 10, in the present case of cards, to a drum-like processing device 12.
- a conveyor 16 designed as a belt conveyor 14 transports the products 10 in the conveying direction F and at conveying speed v 1 to a takeover area 18.
- a transfer conveyor 22 equipped with individually controllable clamps 20 is arranged below the slightly rising conveyor device 16 and is driven to rotate in the direction of rotation U about the axis of rotation 24.
- the clamps 20 move in the same direction as the conveying direction F, the clamp jaw 26 of the clamps 20 moving in the circumferential direction U seen, is directed towards the front and the clamp speed v2 is greater than the conveying speed v1.
- each clamp 20 in the takeover area 18 detects a product 10 at its trailing edge 10 'and transports the product 10 to a transfer area 28 which is approximately diametrically opposite to the takeover area 18.
- the brackets 20 which are articulated on a wheel-like support member 30, are pivoted against the circumferential direction U about a pivot axis 32 running parallel to the axis of rotation 24 about the products 10 with their trailing edge 10 ' Leading edge 10 '' ahead, to insert into pocket-shaped receiving parts 34 of the processing device 12.
- the receiving parts 34 of the drum-like processing device 12 are delimited by walls 36 extending in the radial direction, which have saddle-like supports at their radially outer free ends, which run parallel to the horizontal axis of rotation of the processing device 12, not shown.
- Printed products 40 are laid out astride the supports 38, onto each of which a product 10 is glued in the transfer area 28 by means of the transfer conveyor 22.
- a drum-like processing device 12 of this type is disclosed in CH patent application No. 00 060 / 92-6 and the corresponding EP patent application, publication number 0 550 828. With regard to the structure and mode of operation of the processing device 12, reference is expressly made to these documents.
- drum-like processing devices are known from EP-A-0 341 425, EP-A-0 341 424 and EP-A-0 346 578, and the corresponding US-A-5,052,667, US-A-5,052,666 and US-A-5,104,108.
- a bearing element 44 is wedged on the rotary shaft 24 ′ coaxial with the axis of rotation 24, which is driven continuously in the direction of rotation U via a chain drive 42, on which the wheel-like support member 30 is seated in a rotationally fixed manner.
- the latter has two parallel, round support disks 46 running at right angles to the axis of rotation 24, which are penetrated by bearing shafts 48, in the present case twelve, on a partial circle coaxial to the axis of rotation 24.
- the distance between the support disks 46 is given by the bearing element 44 and spacers 50 which are penetrated by the bearing shafts 48.
- a swivel lever 52 is attached to each of the two ends of the bearing shafts 48, which are freely rotatably mounted on the support disks 46 via the spacers 50.
- the respective parallel pivot levers 52 are connected to one another at their free ends via the pivot axis 32.
- a plate-like first clamping jaw 54 and a second clamping jaw 56 which consists of two clamping fingers 56 ', are freely rotatably mounted on the pivot axis 32.
- the first clamping jaw 54 has plates 58 which are penetrated by the pivot axis 32, are formed on the flat clamping jaw part 54 'and protrude at right angles therefrom.
- the clamping fingers 56 'penetrated by the pivot axis 32 are designed in the manner of double levers, the first clamping jaw 54 projecting above the clamping arm 56 of the clamping fingers 56'. Between the first clamping jaw 54 and the clamping fingers 56 ', one acts around the pivot axis 32 Coil spring 60 to bias the two jaws 54, 56 against each other in the closing direction.
- the clamp jaw 26 formed by the clamping jaws 54, 56 is directed towards the front in the takeover area 18 in the direction of rotation U.
- the first clamping jaw 54 has a freely rotatable pressure roller 62, the longitudinal axis of which runs parallel to the axis of rotation 24 and pivot axis 32.
- a link 64 is articulated on the first clamping jaw 54.
- This is shaft-shaped and extends through a bearing body 66 which is arranged between the support disks 46 and is freely rotatably supported on the latter.
- the link 64 is encompassed by a spring element 68 designed as a compression spring, which is located on one side on the bearing body 66 and on the other side on the link 64 in the vicinity supports its coupling to the first jaw 54.
- the link 64 extends through the bearing body 66 in a freely displaceable manner and has a stop disk 70 at its end on this side which cooperates with the bearing body 66 in order to fix the clamp steering position of the link 64.
- the bearing body 66 is pivotally mounted on the support member 30, offset with respect to the bearing shaft 48 in the radial direction inwards and counter to the circumferential direction U, by means of pins 71, so that the first clamping jaw 54 is articulated on the support member 30 in the manner of a crank gear, the pivoting lever 52 being the crank, the link 64 the rocker and the first jaw 54 form the coupling.
- a control arm like an angle lever 72 integrally formed, which carries a freely rotatable control roller 74 at its free end and on the outer side facing away from the clamping jaws 54, 56.
- These control rollers 74 run in self-contained, groove-like control links 76, which run around the rotary shaft 24 'and are formed on link plates 78 parallel to the support disks 46.
- the link plates 78 are supported on a frame 79 and the rotary shaft 24 'is freely rotatably supported on them.
- the control links 76 are shaped in such a way that in the take-over area 18, the swivel levers 52 are pivoted backwards into the take-over position counter to the direction of rotation U, as shown in FIGS. 1 and 3. Controlled by the link 64, the clamps 20 are pivoted such that the clamp jaw 26 is directed towards the front in the direction of rotation U; this position of the brackets 20 can also be referred to as the takeover position.
- the flat first clamping jaw 54 encloses an acute open angle with a tangent to the orbit, which is only a few degrees (preferably about 10 °).
- the control links 76 are shaped such that the links 64 are pivoted in the same direction as the direction of rotation U toward the front, into a transfer position in which their longitudinal direction runs approximately radially to the axis of rotation 24.
- the first clamping jaw 54 and thus the clamp 20 are pivoted in the opposite direction to the circumferential direction U by a pivoting direction S, so that that of the first clamping jaw 54 and a tangent to the orbit included angle increases (in the transfer position, this angle is preferably about 60-70 °), as shown in particular in FIG. 4.
- a crank 80 is also rotatably mounted on the bearing shaft 48, in each case between the relevant support disk 46 and the pivoting lever 52, which carries a freely rotatable follower roller 82 at its end and is connected via a coupling 84 to the relevant clamping finger 56 'of the second clamping jaw 56 is.
- the couplers 84 are articulated on the clamping fingers 56 'on the side facing away from the clamping arm. In the takeover area 18, opening scenes 86 interact with the follow rollers 82 and are fastened to the scenery signs 78.
- follow-up links 88 are provided in the transfer area 28, which interact with the follow-up rollers 82 in order to prevent the second clamping jaw 56 from also pivoting when the first clamping jaw 54 is opened by the action of counter bearings 90 in order to open the clamp 20.
- These counter bearings 90 are formed in the processing device 12 according to FIG. 1 by the walls 36 or supports 38.
- the wheel-like support disks 46 have recesses 92 on their circumference, into which the clamps 20 engage in the take-over position.
- the sawtooth-like projections between the clamps 20 form with their outer surface 94 a guide element for the trailing edge 10 'of the products 10, the outer surface 94 being flush with the free end of the second clamping jaw 56 or being further away from the axis of rotation 24 with respect to this, if the clamping fingers 56 'are pivoted into their open position, as can be seen from FIG. 1.
- the inner end of the clamp jaw 26 is formed by the plates 58, the leading edge 58 'of which, viewed in the direction of rotation U, forms a stop for the trailing edge 10' of the products 10.
- a guide plate 96 is provided between the transfer area 18 and the transfer area 28 in order to guide the leading edge 10 ′′ of the products 10 during transport by means of the transfer conveyor 22 and to prevent the products 10 from bending backwards.
- lateral guide plates 98 are fastened to the frame 79 in order to take over a side straightening function for the products 10 and a lateral displacement of the products 10 during the takeover by the transfer conveyor 22 prevent.
- guide profiles 100 which are arranged coaxially with the axis of rotation 24, are fastened to the frame in order to support the products 10 on the inner side, seen in the radial direction.
- the transfer conveyor 22 is preceded by an adhesive application device 102, indicated by an arrow (see FIG. 1), in order to apply an adhesive application 104 to the products 10, which is only indicated in FIG. 6 for the sake of clarity.
- the adhesive application device 102 is controlled in a known manner in such a way that it applies the adhesive application 104 at one point of the product 10 attaches, which is in the product 10 gripped by a clamp 20, seen in the direction of the axis of rotation 24, between the clamping fingers 56 'of the second clamping jaw 56 and, seen in the direction of rotation U, between the trailing edge 10' and the pressure roller 62.
- the adhesive application 104 is located on the side of the products 10 facing the axis of rotation 24.
- This location of the adhesive application 104 has advantages which are to be described further below in connection with the transfer of the products 10 to the processing device 12; in principle, however, it is also possible for the adhesive application device 102 to apply the adhesive application 104 at another location. If the products 10 are not to be glued to the printed products, the adhesive application device 102 is switched off, or none is provided at all.
- the conveyor device 16 has a ribbon conveyor 106, the endless conveyor ribbon 108, which is round in cross section and made of elastic material, is guided around deflection rollers 110, 110 'at the beginning and at the end of the takeover area 18.
- the conveyor belt 108 together with the pressure roller 62 of the clamps 20, forms a nip for the products 10.
- the belt conveyor 106 is preceded by the belt conveyor 14, which has a pair of conveyor belts 112, which forms a conveyor gap 112 'between them, around the products 10 in the conveying direction F to the takeover area 18.
- the ribbon conveyor 106 and the pair of conveyor belts 112 are driven at the conveying speed v 1 in the conveying direction F; this is less than the speed v2 of the brackets 20 in the takeover area 18th
- each product 10 is conveyed by means of the conveying device 16 in a scale formation 114 to the takeover area 18, in which each product 10 rests on the leading end.
- the trailing edge 10 ′ of each product 10 thus lies on the trailing product 10 on the side facing away from the ribbon conveyor 106.
- FIGS. 6 and 7, show the takeover area 18 enlarged by two times which are different from each other by half a working cycle.
- the reference numerals correspond to those in FIGS. 1 to 5. If a product 10 leaves the conveying gap 112 ′ with its leading edge 10 ′′, it arrives directly in the takeover area 18, where it is only on the leading area with its area adjoining the leading edge 10 ′′ Product 10 rests. However, it is still held in the conveying gap 112 'and is transported further at the conveying speed v 1 (see FIG. 7).
- a clamp 20 now catches up with the product 10 and presses it with its pressure roller 62 against the conveyor belt 108, see the clamp 20 on the left in FIG. 6.
- the clamp 20 now presses the product 10 onto the conveyor belt 108 with the pressure roller 62, as a result of which the product 10 is also held when its trailing edge 10 'has left the conveyor gap 112', see the second clamp in FIG. 7 20 from the left.
- the pressure roller 62 pressing the product 10 against the conveyor belt 108 runs off the conveyor belt 108 and the trailing clamp 20 is closed in order to grasp and hold this product 10 at the trailing edge 10 ', see FIG. 6 clamp 20 on the far right and in FIG. 7 the two brackets 20 on the right.
- the products 10 are thus always held and guided until they are gripped by a clamp 20. Your position is always precisely determined. This allows a large processing capacity and in particular an arbitrary position of the conveyor 16 and the transfer conveyor 22.
- the clamps 20 hold the products 10 securely, since the bending of the products 10 and the lifting of the conveyor belt 108 by the clamp 20 to be grasped the product 10 ensure that the product 10 with the trailing edge 10 ′ of the conveyor belt 108 or the trailing one Product 10 lifts off and is overlapped by the first jaw 54.
- the guide profiles 100 and the outer surface 94 ensure that the second clamping jaw 56 engages the product 10.
- an exact alignment of the products 10 is ensured by the fact that the edges 58 'of the plates 58 run onto the trailing edge 10' of the products 10.
- the guide surface 98 prevents the products 10 from being twisted or laterally sheared out.
- FIGS. 8 and 9 Another embodiment of the conveyor 16 in the takeover area 18 is shown in FIGS. 8 and 9.
- the conveyor belt 108 of the ribbon conveyor 106 is guided around the stationary deflection roller 110 at the end of the conveying gap 112 'and the stationary deflection roller 110' at the end of the takeover area 18 and is also driven in the conveying direction F at the conveying speed v 1.
- a first pressure wheel 118 is provided, which is arranged between the two runs of the conveyor belt 108 and is freely rotatably mounted on the free end of a lever 120 which is pivotally articulated on the other end on a bearing plate 122 of the conveyor device 16.
- a tensioning wheel 124 is freely rotatably mounted about the pivot axis 120 'of this lever 120 and presses the upper inactive strand of the conveyor belt 108 in the direction of the lower active strand between the deflection roller 110 and the first pressing wheel 118. Furthermore, between these two strands and, seen in the conveying direction F, between the tensioning wheel 124 and the deflection roller 110, a second pressure wheel 126 is provided, which is freely rotatably mounted at the free end of a further lever 128, which in turn is pivotably mounted about the axis of the deflection roller 110 is. Between the deflecting rollers 110 and 110 'there are thus two elastically yieldable supports which counter the conveyor belt 108 in the downward direction the transfer conveyor 22, press. The downward force is generated in each case by the upper non-active run of the conveyor belt 108, which elastically prestresses the pressure wheels 118, 126 against the bottom due to the stationary tensioning wheel 124.
- the products 10 supplied with the conveyor 16 are taken over by the clamps 20 of the transfer conveyor 22 in basically the same way as in the embodiment according to FIGS. 6 and 7 It has been shown that as a result of the multiple, elastic support of the conveyor belt 108 in the takeover area 18, between the deflecting rollers 110, 110 ', the processing capacity can be increased further by a greater conveying speed v 1 with the same reliable and safe transfer of the products 10 and higher clamp speed v2 are permissible. The products 10 are also held over a longer path.
- a product 10 (FIG. 9) leaving the conveyor gap 112 'of the conveyor belt pair 112 is picked up by a clamp 20 and pressed with the pressure roller 62 against the conveyor belt 108 before the trailing edge 10' leaves the conveyor gap 112 '(FIG. 8) .
- the product 10 is now transported further at the conveying speed v 1, whereas, due to the higher clamp speed v 2, the subsequent opened clamp 20 catches up with the product 10 and comprises it in the area of the trailing edge 10 '.
- the pressure roller 62 By deflecting the conveyor belt 108 in the upward direction, by the pressure roller 62, the product 10 is again bent and by the pressure wheel 126 in the direction pressed against the bottom, against the top of the jaw part 54 '(FIG.
- FIG. 10 shows the device according to the invention in the same representation as FIG. 1, but the conveyor device 16 transporting the products 10 to the takeover area 18 is designed as a gripper conveyor.
- This has a dash-dotted line, guided in a channel 130, endless traction element 132, which is driven in the conveying direction F at the conveying speed v 1.
- Individually controllable grippers 134 are attached to the traction element 132 at a fixed distance one behind the other.
- Grippers 134 of this type are disclosed, for example, in Swiss Patent Application Nos. 00 495 / 92-8 and 00 496 / 92-0.
- Each gripper 134 holds a product 10 at its upper edge, which becomes the leading edge 10 ′′ when the product 10 is supported in the otherwise freely hanging area of the lower edge, which then becomes the trailing edge 10 ′.
- the transfer conveyor 22 is arranged below the conveyor device 16 and is essentially of the same design as described above and shown in FIGS. 1 to 5. This is expressly referred to. The differences to this are described in detail below.
- U driven pulleys 46 are hinged in the same way via pivoting levers 52 clamps 20, the pivoting position about the pivot axis 32 in turn via a handlebar 64 acting on the first jaw 54, depending is controlled by the pivot position of the pivot lever 52.
- the pivot position of the pivot lever 52 is given via the control roller 74 which is guided in the control link 76 of the link plate 78.
- the second jaw 56 is in the closed position against the first jaw 54 biased and is brought into the open position by means of the opening gate 86, which cooperates with the follower roller 82.
- the follower roller 82 is mounted on the crank 80 and is connected to the second clamping jaw 56 via the coupling 84.
- a follow-up backdrop 88 is also provided, which interacts with the follow-up roller 82 in the transfer area 28.
- the clamps 20 on the first clamping jaw 54 have no pressure roller 62.
- no lateral guide surfaces 98 and guide profiles 100 are provided.
- the guide plate 96 guides the products 10 in the area of their leading edge 10 ′′ when they are introduced into the receiving parts 34 of the processing device 12 designed in the manner of a drum.
- the transfer conveyor 22 is preceded by the adhesive application device 102, the distance of which, measured in the vertical direction, from the orbit of the gripper 134 is smaller than the length of the products 10, so that the area adjacent to the trailing edge 10 'is slid over the adhesive application device 102 and the adhesive application 104 can apply.
- the distance between the conveying device 16 and the transfer conveyor 22 is substantially smaller than the length of the products 10 from their leading edge 10 ′′ to the trailing edge 10 ′, so that the product fed to the transfer region 18 with its central region onto a clamp 20 and with its trailing edge 10 'on which this bracket 20, seen in the direction of rotation U, trailing outer surface 94 of the support disks 46 comes to rest.
- the pivoting levers 52 due to the shape of the control link 76, are pivoted forward in the area following the takeover area 18 in the same direction of rotation as the direction of rotation U until they are approximately in the transfer area 28 run in the radial direction.
- the quadrilateral control of the pivoting position of the clamps 20 via the links 64 they pivot in the opposite direction of rotation S in the direction of rotation U.
- the clamp jaw 26 is thus directed towards the relevant receiving part 34 of the processing device 12.
- the transfer conveyor 22 and the processing device 12 are matched to one another in such a way that a clamp 20 reaching the transfer area 28 is seen in the direction of rotation V of the drum-like processing device 12, approximately in the middle between two Walls 36 and thus a receiving part 34 comes to rest. Since the clamp speed v'2 is greater than the peripheral speed v3 of the supports 38 of the processing device 12, the clamp 20 now catches up in the transfer area 28, seen in the direction of rotation U and direction of rotation V, leading wall 36. The product 10 is brought into contact with this wall 36 or with a printed product 40 lying against this wall 36. The product 10 is then released by opening the relevant clamp 20.
- Different possibilities of transferring the products 10 to the processing device 12 will now be described in more detail with reference to FIGS. 11 to 15.
- FIG. 11 shows a part of the transfer conveyor 22 and the processing device 12, which enlarges the embodiment shown in FIG. 1.
- the position of a clamp 20 feeding a product 10 to the processing device 12 and a printed product 40 straddling a wall 36 of the processing device 12 are shown at intervals of half a work cycle.
- the position of the bracket 20 at the full work cycles can be seen in that the linkage to the support member 30 is shown. Only a part of the bracket 20 is shown shifted by half a working cycle.
- the wall 36 is only shown in the positions it occupies during the full work cycles. Only the printed product 40 is indicated in between.
- the product 10 held by the clamp 20 slides with its leading edge 10 ′′ along the guide plate 96. This ends at a short distance from the orbit
- the processing device 12 and the transfer conveyor 22 are synchronized in such a way that the leading edge 10 ′′ of the product 10 penetrates into a receiving part 34 approximately in the middle.
- the pivot lever 52 has not yet been pivoted completely into the transfer position. The remaining pivotal movement has the result that the product 10 is inserted into the receiving part 34 at an increased speed and at the same time the difference between the clamp speed v'2 and rotational speed v3 of the support 38 is increased.
- the clamp 20 catches up the leading wall 36 in the takeover area 18 and presses the product against the printed product 40 with its pressure roller 62, which is supported by the wall 36 acting as a counter bearing 90. Since the clamp speed v'2 is greater than the rotational speed v3, the first jaw 54 is pivoted counter-clockwise against the force of the spring element 68. The follower link 88 cooperating with the follower roller 82 prevents the second jaw 56, which is resiliently biased against the first jaw 54, from following this pivoting movement. This opens the clamp 20 and at the same time presses the product 10 against the counter bearing 90. In the course of the further movement, the pressure roller 62 now rolls on the product 10 and presses its adhesive application 104 onto the printed product 40. This ensures reliable bonding.
- the clamp 20 closes, insofar as the link 64 and the follow link 88 allow this.
- the clip 20 is closed completely at the latest when the following roller 82 runs from the following backdrop 88.
- the pivot lever 52 is then pivoted back into the take-over position, as a result of which the clamp jaw 26 is again directed forward in the direction of rotation U.
- the clamp 20 approaches the takeover area 18, it is opened as a result of the action of the opening link 86, whereby it is ready for the detection of a product 10.
- the embodiment according to FIG. 10 functions in the same way as described above. The only difference is that the free end region of the first clamping jaw 54 acts as a sliding shoe when the product 10 is pressed against the counter bearing 90.
- FIG. 12 corresponds exactly to FIG. 11, only the distance between the axis of rotation 24 of the transfer conveyor 22 (see FIG. 1) and the axis of rotation of the drum-like processing device 12 being reduced. The consequence of this is that the clips 20 engage deeper in the receiving parts 34 and the products 10 are thus glued to the printed products 40 at a corresponding other location. It should be noted that the supports 38 engage in the recesses 92 of the support disks 46 without contact.
- FIG. 13 also shows the transfer conveyor 22 and the drum-like processing device 12 according to FIG. 1 in an enlarged manner in the transfer area 28.
- the only difference from the variant according to FIG. 11 is that the products 10 are not provided with an adhesive application.
- the products 10 are in turn with their leading edge 10 ′′ ahead by means of the transfer conveyor 22 in a receiving part 34 of the processing device 12 is inserted.
- the relevant clamp 20 in turn catches up with the leading wall 36 and presses the product 10 with its pressure roller 62 against the printed product 40 supported by the wall 36 acting as a counter bearing 90.
- the clamp 20 is in turn opened in that, as a result of the action of the counter bearing 90 the first clamping jaw 54, counter to the action of the spring element 68, is pivoted counterclockwise and the following jaw 88 is prevented from following the pivoting movement 56 by the following link 88. As soon as the pressure roller 62 has rolled on the product 10, it falls into the bottom of the receiving part 34.
- the processing device 12 has a processing conveyor 136, the conveyor belt 138 of which is driven in the transfer area 28 in the direction of removal W, the direction of rotation U in the same direction.
- the conveying speed v3 is less than the rotational speed v'2 of the pressure rollers 62 of the clamps 20 in the transfer area 28.
- On the conveyor belt 138 there are printed products 40, onto each of which a product 10 is deposited and optionally glued.
- the conveyor belt 138 is supported by a support element 140 so that it can serve as a counter bearing 90.
- the transfer conveyor 22 is of exactly the same design, as shown in FIGS.
- the products 10 are deposited on the printed products 40 by means of the transfer conveyor 22, the leading edge 10 ′′ now becoming trailing with respect to the trailing edge 10 ′ due to the pivoting movement of the clamps 20. Since the uninfluenced orbit of the pressure roller 62 cuts the conveyor belt 138, the pressure roller 62, under the force of the spring element 68, in turn presses the product 10 against the printed product 40, as a result of which the first clamping jaw 54 is pivoted counterclockwise. As a result of the action of the counter bearing 90, the conveyor belt 138 cannot evade the action of the first clamping jaw 54. The follow link 88 in turn prevents the second clamping jaw 56 from following the pivoting movement of the first clamping jaw 54, as a result of which the clamp 20 is opened.
- the product 10 is again pressed onto the printed product 40. If the product 10 is provided with an adhesive application 104, this in turn leads to a secure adhesive connection. If there is no adhesive application 104 on the product 10, it is securely guided onto the corresponding printed product 40 or, if there is none, on the conveyor belt 138.
- control link 76 in such a way that the pivoting of the pivoting levers 52 from the transfer position back into the transfer position already begins in the transfer area 28, while the product 10 is still pressed on.
- the distance between the clamps 20 is greater than the distance between the trailing edges 10 'of the takeover area 18 Products 10.
- the distance between the clamps 20 in the transfer area 28 is greater than the distance between the supports 38.
- the wall 36 leading in front of a clamp 20 is brought about solely by the pivoting movement of the pivot levers 52.
