Description

The invention relates to a device for producing book covers from a covering material Lining pieces attached by gluing, with a pressure pad carrying the cover, a around the pressure pad extending frame, a Änpreßplatte carrying the piece of lining, which for Applying the piece of lining to the cover material is displaceable against the pressure pad, the edges of the covering material around the edges of the lining piece by sliding folding sheets are foldable and can be pressed onto this.

In a known device of this type (French patent specification 1124219) the Edge areas of the pressure plate withdrawn upwards as soon as the piece of food on the pressure pad is upset. Depending on the type of material used for the cover, these are upwards standing parts of the coating are not stiff enough so that they bend and z. B. partially with come into contact with the lining piece, so that it is no longer possible to use the folding sheets to bring about uniform, wrinkle-free application of the coating to the piece of food. Then becomes the coating shifted upwards with the pressure pad to move the edge parts of the cover against the fold

to press the leaves and thus complete the adhesive bond, the due to the uneven The wrinkles created by the system are flattened and no longer removed.

In an alternative apparatus of this type (German ¹ see Patent 76 397), a pressure pad for supporting the coating, a mold for placement of the food piece, means for moving the mold for the purpose of placing the food piece in the proper location on the coating, movable folding blades ίο for inwardly folding the marginal edges of the cover and then pressing the edges into adhesive contact with the liner, as well as means for bringing about these movements of the folding sheets. The cover is made of flexible material, which, however, is reinforced by a non-flexible, rigid piece of lining, so that no external carrier or support device is required. Furthermore, the cover is stretched over the edges of the piece of food, which must have the rigidity required for this method so that only rigid bindings can be produced with the aid of this device.

Finally, it is also a method for obtaining book covers, album covers or the like are known, in which a composed of a solid material cover board with a coating, for example paper, fabric, plastic or the like is provided or from German Patent 953,431. In this way, however, only a rigid cover can be produced.

Book covers are usually made from a single piece of cover material, such as leather, book cloth, Paper od. The like. Flexible material and one or more, usually made of thin cardboard or Paper made of existing liner pieces. The lining pieces must be attached to the back of the binding piece be precisely aligned in the required position, with a uniform edge section must protrude around the entire circumference of the liner. This exposed edge section must then be bent evenly and firmly upwards around the edge of the lining and downwards be pressed. It is also necessary that the linings and bindings be firmly glued together are done, which is sometimes done along the tucked edge, but in all places where the parts are in contact with each other. Because of the past and present Used wet or tacky adhesives, binders and pastes will use this process itself still mostly done by hand today. By dividing the work among several workers and the use of conveyor belts, gluing machines, fixtures, etc., while it is possible to achieve substantial production numbers economically, but is the number required for this Workforce quite large. Furthermore, the labor cost per piece is comparatively high and it is expensive monitoring is required in order to keep such a manufacturing plant operational.

In contrast, the object of the invention is to provide an improved device for producing book covers to create from flexible covering material, in which the aforementioned disadvantages are not appear.

This object is achieved in that the working surface of the pressure plate from on Perimeter distributed arranged segments consists, which in the general plane of the work surface between an outer layer which is used to fold over the edges of the covering material and in which their free edges substantially cover the edges of the liner, and an inner layer are slidable, in which their free edges from the edges of the folded over and onto the lining piece to be pressed edge of the coating material are away and that heating devices for activation of adhesive layers are provided.

According to the invention, the covering material is removed from the folding sheets after the lining piece has been inserted before the segments attached to the pressure plate are withdrawn inward. In order to is advantageously achieved that with particularly light coating materials, the segment parts Smooth out the folds caused by folding over the edge to be glued when pulling back, before this edge is glued to the folding sheets by pressing.

In addition, the bindings made according to this process are more uniform in size and shape as hand-made bindings and even those made in a number of mechanized devices and are therefore in the ones used for embossing the covers and assembling the book Machines easier to use. Good quality is obtained at a lower cost.

The device can be used to manufacture objects with right-angled corners as well as Objects with a shape other than square or rectangular, for example circular or elliptical pieces. It can be used when assembling any Use a combination of flexible covers and lining pieces, with the exposed edge of the Binding partially or completely bent over the adjacent edges of the lining and to be glued to these.

The folding rail actuation device for lateral movement moves the front and rear seam rails inward toward the center of the fixture moving the attached folding sheets so that the edges of the covering material be folded over the lining piece in one straight motion from front to back. This movement is made possible by two cams provided with appropriate slots for the longitudinal folding movement ·. · Produced. These cams are mounted so that they are relative in the circumferential direction to each other and also be adjusted relative to the cam for longitudinal folding movement in order to achieve the greatest possible adaptability to the mode of operation of the folding sheets to guarantee. The longitudinal movement folding rail actuator moves four grooves in the front and rear folding rails Operating joints for longitudinal movement. These joints are operated by levers, which Swing back and forth on shafts provided in the device foundation. One shaft operated at a time two of these joints; actuation is made possible by the use of forked levers, which a Allow up and down or to and fro movement of the articulated operating blocks in the levers and thus the movement regardless of the position of the folding rails with respect to the shafts and levers transferred to the associated joints. This device is provided by the one on the main shaft Cam actuated for longitudinal movement. This movement causes the four folding sheets to become moved inwardly towards the center of the device, around the edges of the cover material over the liner to fold and stick to it.

The molded part actuator is operated by a cam attached to the main shaft actuated, which drives a cam disk provided on the rear shaft around which the mold forms four shoes in chronologically coordinated relationship to the other folding processes extend and retract.

The lifting and lowering device for the upper part of the mold is also carried out by one on the main shaft attached cam actuates and causes a lowering and lifting of the upper part of the mold the shape protruding downward from this in a time-controlled relationship with respect to the others Folding operations.

The coating material conveyor is arranged by a series of on the main shaft Controlled cams that cause the conveyor arm to remove the coating material after it has been shaped picks up and promotes to the heat gluing device.

The heat sealer can be driven at various speeds and will grip that molded cover material and conveys it to two conveyor belts, which it for example to thermostatically regulated heating devices, whereby the entire piece of lining with the covering material is glued. Two finishing press rollers are also provided, all in the cover material Smooth or iron out any irregularities such as wrinkles or the like.

The mold is practically under a continuous vacuum to hold the pieces of food thereon, while the vacuum supply to the conveyor arm is controlled by a valve which is controlled periodically and in timed relation by a cam provided on the main shaft . . ■. ■;

The device according to the invention is explained in more detail below.

ίο F i g. 1 shows a perspective view of a Part of the device in which the folding sheets 24 are aligned for the insertion of a covering material and an upper part of the mold is raised to its position of readiness for inserting a piece of food

The layered pressure pad 20 is designed so that it is capable of receiving the cover material and forms the resilient member for supporting and holding the cover material and the liner during the pressing process. Size of the pressure pad corresponding to the final size of the book cover to be formed, and thus the size of which is reduced to the pressure pad 20 as the mold, to 'the chuck pieces and the coating material during the molding passage ψ noted. Since the covering material is larger than the pressure pad, the alignment templates 21 are aligned with respect to the pressure pad 20 such that their marginal edges protrude in the correct width over the pressure pad 20 in order to be able to fold them up and over the piece of lining. The alignment templates 21 are also used as stiffening members during the folding process. The templates 21 are held rigidly on the main switch 23 by fastening and adjusting screws 22.

The folding sheets 24 are attached directly under the alignment templates 21 and with the help of flat washer strips 27 penetrating studs 26 on the spacer 25 of a respective Fold movement blocks 29 attached and anchored to this. The folding sheets 24 are provided with slots 28 provided that allow centering and alignment. The spacer 25 is on the corresponding Movement block 29 is attached and operated by it, the block in turn on a rail 32 is attached and is actuated by an actuating member 30 in longitudinal movement and with the help of studs 31 is connected to this. So it can be seen that the entire folding table is moving with an upward and downward movement of the folding rails 32, one of which each on the front and Rear of the device is fixed and moves up and down, while the main frame 23 of the folder rests on the movement blocks 29.

In addition, the member 30 moves the folding sheets 24 with the aid of the reciprocating motion Movement blocks 29 and their spacers 25 in the longitudinal direction. During the transverse movement of the Folding rails 32 transmit a similar movement to the folding sheets. These movements serve hence, first of all, lifting the edges of the covering material around the liner and then to fold the covering material inward over the lining piece and the molding segment, while later after removing the mold segments they press the inwardly creased edges allow the coating material to lower the leaves down onto the liner. More obvious-

wise are the foundation sections of the device covered with covers 33 held by screws 34 to keep dirt and dust and other undesirable Keep away deposits on the facilities arranged in the foundation.

A pivotable upper mold part 35 has a frame 37 with two attached to the rear shaft 36 Bracket arms 38 and 39 on. The shape consists of four segments 40, each with the help of is movable by holders 41 to expand or retract the shape before and after the hemming process. The piece of food is placed on a form pressure plate 42 and on this through holes 43 and 44 held until it is deposited in the coating material. The piece of food is made with the aid of side templates 45 provided on a template mounting block 48 and 46 and a rear template 47 held on the pressure plate 42 in the correct position. The mounting block 48 is resilient to the brackets 38 and 39 of the by means of rods 50 and 51 Upper part frame attached and is provided on the bracket arms 38 and 39 stops 52 and 53 held. When the mold is lowered, the template strips are in contact with the alignment templates 21 moved upwards out of the path of movement.

The rear shaft 36 is supported at both ends in self-centering bearings 54 and 55. This Bearings are inserted into arms 56 and 57 of the frame and thus form a circumferential link on the rear side of the frame to enable the molded part to be operated and to lower the upper part of the mold 35. The actuation of the mold or segments 40 to expand and retract the same takes place through a joint 59, which, as will be described in more detail later, moves in a straight line is actuated to thereby cause a rotary oscillatory movement of a motion transmission bracket 60 through an arm 61. This movement is applied to a shaft 36 attached to the rear Transfer sleeve 62, which is prevented by adjusting rings 63 and 64 from a longitudinal displacement will. At one end of the sleeve 62 a cam 65 is attached to actuate the mold, while at the other end of the movement transmitting bracket 60 is attached, so that the entire Arrangement according to FIG. 8 is able to swing back and forth on the shaft 36. The swinging movement of the Cam 65, which has a rectangular cam groove 66, transmits a straight back and forth Movement on a bracket 67, which has a bracket sliding on the sleeve 62 and one on its one Has side attached driver member 69 to come with the cam groove 66 in engagement and to produce an actuation movement for the form. The following are done in order Operations: lowering of the upper part of the mold with the extended one arranged on the pressure pad Form, then forming the folds of the coating material over the form, withdrawing the Forming and lifting the same into position for inserting a new piece of food.

The upper mold part 35 has on its front side an adjusting nut 70 for a back and forth size adjustment the shape as well as studs 71 and profile pieces 72 for lengthwise size adjustment the shape. The vacuum supply to the mold platen 42 to hold the chuck in place takes place via a vacuum distribution line 73 and

In Fig. 2, the upper form part 35 is omitted and the folding device is closed in the folding position Folding sheets and folding movement rails lowered into this position are shown. The joints 30 for longitudinal movement have moved the folding sheets longitudinally into the device,

ίο while the folding rails 32 through the device for the transverse movement from the back ■ moved to the front in order to find all the folding sheets in the to bring them fully into the folded position in the correct order. In addition, the fold-lifting device has the entire arrangement is lowered onto the pressure pad 20. "·

In FIG. 3, the alignment templates 21 are not shown, and the folding device is illustrated with the folding sheets in the insertion position, while the folding-lifting device is also in the insertion position. The in F i g. 3 A shown folding sheets 24 A and 24 B show how the overlapping ends are formed in order not to have to change the thickness of the folding sheets. The hatched areas 76 and 79 are milled off on the upper side to half the panel thickness, while the other two areas 77 and 78 are milled off on the underside in order to allow the sheets to overlap or push together without changing the thickness. In addition, it can be seen that the slots 80, 81, 82 and 83 forming the corners are elongated in shape so that the right-angled corners can be formed while avoiding thick creases. To form such right-angled corners, the folding movement is coordinated so that the folding sheets are first moved crosswise from the front and back inwards towards the center and then endwise or in the longitudinal direction towards the center, so that a right-angled corner fold of minimal thickness is produced before pressing will. The two in FIG. 3 B illustrated folding sheets 24 D and 24 C illustrate how the overlapping ends are designed so as not to have to change the thickness of sheets 24 α and 24 b , and also leave the formation of the corners and the type of sheet actuation recognize. When forming round corners, the movement is modified to such an extent that all four sheets are moved inwards at an angle of .45 ° by performing the transverse and longitudinal sheet movement simultaneously and not gradually as when forming right-angled corners. How this operation is performed will be described later in connection with the operation of the main shaft.

In Fig. 4 the folding sheets are also omitted, around the folder main frame, the pressure padding and to make the frame surrounding the pressure pad visible. The folder main frame 23 rests on the movement blocks 29 and can be moved up and down by these, when the fold elevator moves the fold rails 32 up and down. The frame 23 is arranged around the pressure pad 20 and is therefore in its vertical movement by this guided. Lateral rails 86 and 87 are provided to the left and right of the pressure pad 20, while T-shaped rails 88 and 89 are arranged in front of and behind the pressure pad 20, from

j The following is the folding rail lifting device on the basis of F i g. 20 described in more detail. \ In the device according to the invention, two folding rails are used, one of which each extends over; the front and are extended beyond the rear side of the ■ \ apparatus and both simultaneously actuated by the joint rails-Anhebbewegungseinrichtung. Two folding rail lifting shafts 126 and 127 are arranged on the device foundation and extend on the left and right side of the device from the front to the rear thereof. Lifting levers 128 , 129, 130 and 131 are pinned to these shafts 126, 127 and are actuated by them. The front levers 128 and 129 are connected to downwardly projecting actuating arms 132 and 133 , which have slots 134 and 133 at their free ends and are also provided with drivers 136 and 137 , which with the help of adjusting studs 138 and 139 for the driver 136 and adjusting studs 140 and 141 for the driver 137 in the slots 134 and 135 are adjustable. The drivers 136 and 137 run on the left and right folder lifting cams 142 and 143, respectively, in order to produce an oscillating movement for lifting and lowering the folding sheet arrangement with respect to the pressure pad. The adjustment options provided at the lower ends of the actuating arms 132 and 133 serve to align and synchronize the mode of operation of the two sets of levers. The actual amount of lift imparted to the fold rails 32 is controlled by four adjustable lift stoppers 144, 145, 146 and 147 located on the lower surfaces of the front and rear fold rails 32 immediately above the lift levers in contact with them. Both lifting cams 142, 143 are keyed to the main shaft 100 and attached to it and are thus driven synchronously by the latter.

Next, the folding rail actuator for transverse movement is discussed in connection with FIG. 21 described. This mechanism moves the front and rear fold rails 32 inwardly toward the center of the machine and always keeps them parallel to each other to move the fold sheets inward over the pressure pad and fold the cover material inward over the liner. In this device, two flat, right-angled rails are provided which penetrate the foundation in order to couple the actuation of the two folding rails with one another and thereby allow them to be actuated together.

The left and right folding device guide rails 150, 151 are arranged as right-angled, flat strips below the folding rails 32 and can be moved at their front ends with the help of sliding groove blocks 152, 153, 154 and 155 attached to the underside of the folding rails, but are rigidly connected to these folding rails at their rear ends. These blocks are provided with downwardly directed fork pieces 156, 157, 158 and 159 , which form the actuating device to move the two folding rails back and forth completely parallel to one another. The device is actuated by three actuating arms 160, 161 and 162 which are combined to form an actuating element and which can be attached to the underside of the foundation in an actuating element holder 163 . The two arms 160 and 161 are formed on their outer surfaces to receive eccentric bolts 166 and 167 which are held by screws and nuts and connected to the fork pieces 156 and 157 , while at the same time allowing adjustment of the actuating parts to to maintain the parallelism between the front and rear folding rails 32 . The lower, downwardly directed actuating arm 162 has on one side a cam follower 168 which is actuated by the slot provided on cam 169 for the transverse movement. The rear folding rail 32 is supported by a similar one shown in FIG. 8 is driven and actuated by the cam 171 arranged on the cam 170 for the longitudinal folding movement for the transverse movement. The holder provided at the rear end is arranged rotated by 180 ° in order to align the actuating arm located on the right-hand side for engagement in the curve 171.

In the following, the actuating device for the longitudinal folding movement is now based on FIG. 22 explained. This device is capable of moving the folding sheets in and out toward and away from the center of the device in order to fold the cover material over the liner. As with the other movement device, two shafts arranged in bearings provided in the base frame 103 are also provided here in order to coordinate the modes of action on the front and rear and to adapt them to one another. The shafts 178 and 179 are each provided at their two ends with non-rotatably pinned, forked actuating levers 172,173,174 and 175 , which are actuated by an arm 176 protruding downward from the fork actuating lever 172 , which has an inwardly directed cam follower 177 for engaging an in Has circumference of the curve 170 provided for end-fold folding movement circumferential control groove. This control groove transmits an oscillating movement to the fork actuating lever 172, which in turn transmits this oscillating movement to a movement transmission block 180 arranged in the fork section of the lever. This arrangement enables the up and down folding movement with respect to these operating levers as well as the inward and outward folding movement performed by the levers. In the tops of the front and rear Falzschiene 32 slots provided, the actuating members 30 is arranged for longitudinal movement, which are pinned to the in the fork pieces of the lever 172 to 175 attached to blocks 180 and ensure the longitudinal folding movement in that they go into the slots - and are moved and set the fold motion blocks 29 attached to them in motion. The transmission of the movements is ensured by the fact that the lower outer ends of the forked actuating levers 172 to 175

209 537/1

by means of. Brackets 182 and 183 are coupled to one another, which in turn is resilient by one on one attached plate 184 welded connecting rod are coupled together. Plate 184 (Figs. 7 and 8) is by means of hinge-like, only an up and down movement of the connecting rod universal fastening devices in a single perpendicular plane 185 and 186 resiliently attached to the side plate 107 of the device. Obviously made possible and this arrangement ensures the transmission of a uniform amount of motion, whereby, the actuation of the members 30 in the folding rails 32 is always the same. As shown in FIG. 22, it can be seen, the ends of the universal stiffeners at the extreme ends of the stirrups 182 and 183 can be adjusted to ensure uniform length and displacement of the links 30. In addition, the displacement of the hemming movement block relative to the link 30 and 40 allows its attachment to it with the help of the studs 31 an additional adjustability.

In this connection it should be pointed out that the rear curve 171 attached to the left end of the curve 170 for the longitudinal folding movement for the transverse movement as well as the one shown in FIG. 7, front curve 169 attached to the right-hand side of this curve are fastened to curve 170 so as to be adjustable for transverse movement in the radial direction in order to be able to change the working sequence of the folding sheets 24. In FIG. 23, the main shaft 100 supported in the bearings 101 and 102 is shown with the curve 170, which has two hubs for centering and fastening the transverse movement curves. The transverse folding movement curves 169 and 171 are provided with a slot for their adjustment taking place in the circumferential direction and their fastening with screws 189 and the nut 190 and have three receiving bores for a screw 187 cooperating with a nut 188, with the help of which they are located on both end faces the -. Curve 170 arranged and thus the working order of the folding sheets can be changed. In the block diagram according to FIG. 23 A the various working sequences are shown schematically, which can be achieved by adjusting the transverse movement curves in the radial direction with respect to the longitudinal movement curve in order to produce these movements. According to the diagrams in FIG. 23 A results in the following relationships:. .

Left: The front and rear transverse movement curves 169 and 171 move the folding sheets 24 first in the transverse direction (1) inwards towards the pressure pad, whereupon the longitudinal movement curve the Folding sheets 24 moved longitudinally inwards (FIG. 2) against the pressure pad in order to fold the cover material in an inward direction over the lining piece and complete the shape.

Middle: The folding longitudinal movement curve 170 first moves the folding sheets 24 in the longitudinal direction (1) against the pressure pad, and then move the front and rear lateral motion curve 169 or 171 the folding sheets 24 in the transverse direction inwards (2) towards the pressure pad in order to fold inwards of the coating material over the liner and the mold.

Right: The longitudinal movement curve 170 as well as the front and rear transverse movement curve 169 and 171 move the folding sheets24 simultaneously, inward, around, as shown, an angle of 45 ° with respect to the pressure pad running on this Bring movement and perform the inward folding of the cover material in one operation.

The movements described above under "Left" and "Middle" are used in conjunction with the folding sheets 24 A and 24 B according to FIG. 3A in order to produce bindings with right-angled corners. The forming sequence can be modified to form the cover material as desired: In either direction over the liner. . ..-.-.

The movement described under "Right" is used in conjunction with the folding sheets 24 C and 24 D for rounded corners as shown in FIG. 3 B used only for the production of bindings with rounded corners, the control of the cover material producing very smooth corners at the corners. This process will be described in more detail later in connection with another figure. It should be noted, however, that when forming rounded corners, the pressure pad and the contour of the mold must be adapted to one another and must therefore work together evenly in order to ensure flat corners with evenly distributed excess material.

· ■■ The upper part lifting and lowering device is in Fig. 18 and in FIGS. 7 and 8 and is now based on these figures explained in more detail. The upper mold actuation cam attached to and keyed to main shaft 100 204 is used to actuate this part of the device, while the back of the curve is additional serves as a sliding guide for the entire actuating device.
