Definitions

  • the invention relates to a machine for collecting printed sheets, which has a continuous saddle-like conveyor, a plurality of loading devices for feeding printed sheets onto the conveyor belt, a stapler with a stapler head and reciprocal devices for receiving the collected printed sheets from the conveyor chain and to feed them towards the stapler head.
  • the printed sheets are collected on a spine-like saddle, with the two sheets spread apart on it.
  • the printed sheets are then collected, with the individual sheets being fed step by step along the saddle to the stapling station, where the book is stapled along the spine, which is usually done with staples.
  • the gradual forward movement of the book to the booklet takes place with the help of a gripper on a gripper bar, this gripper bar executing a horizontal back and forth movement.
  • the book After the book has been stapled, it is transported to a delivery point, where pairs of rollers are provided in order to convey the finished book, for example to a cutting station, for re-cutting at the top and bottom.
  • the book is still lifted off the saddle, using a so-called folder, and gets into the curvature of take-off rollers.
  • the invention has for its object to improve a machine of the known type in such a way that such vibrations are eliminated, especially when they are close to the natural vibration number of the transport chain.
  • devices for reducing vibrations are provided in the conveyor chain, including a lower bar which is attached above the return of the conveyor and a continuous guidance of the return over its entire length.
  • a further advantageous embodiment provides that an end gear is attached to the end part of the return of the conveyor and devices for driving the end gear.
  • devices are provided for damping the vibration of the conveyor chain by attaching a flywheel to the main drive shaft between the first and second devices.
  • the end gear is provided on the end part of the return of the conveyor chain and devices for driving the end gear are provided.
  • the invention has the effect that the chain vibration is controlled and these disturbing natural vibrations can be eliminated with simple measures.
  • the invention is explained in more detail in the following description with reference to exemplary embodiments shown in the drawings.
  • the machine 10 shown in FIG. 1 for collecting printed sheets has a feed chain or conveyor 12, which is usually in the form of a saddle-shaped conveyor.
  • the individual printed sheets are arranged on the saddle conveyor in a spread form in a plurality of insertion pockets 14.
  • a button 16 which measures the thickness of the book to ensure that none of the sheets are missing.
  • the books are advanced to a stapling station which is provided with the reference number 18. This movement of the books is brought about by a horizontal, reciprocal gripper.
  • the stapling machine has a base 20, a gripper bar drive 22, a cam-operated part 24 and a gripper bar slide 26.
  • the finished books are removed from the stapling station with the help of the same grippers that have transported the books over the supply chain.
  • the books are advanced to a delivery point where a vertically movable finishing sheet is attached under the saddle.
  • the finishing sheet causes each book to be lifted off the saddle and brought to the transport means 28.
  • the transport takes place in the direction of arrow 30 to a book trimming machine 32.
  • the book trimming machine cuts each book up and down so that the corners are flat.
  • All components of the collecting machine 10 are driven by a main drive unit 34.
  • the mechanical force to the individual parts is transmitted by a main drive shaft 36.
  • an end portion of the return gear drive is generally indicated at 38.
  • the structure is described in detail below.
  • the right end of the drive shaft is connected to the gripper bar drive unit 22 of the stapler.
  • a flywheel 40 is arranged between the main drive 34 and the gripper bar drive 22. The task of this flywheel will be described later.
  • the gripper bar drive 22 is provided with a speed reducer. This speed reducer exits via the drive shaft 42, which is provided with a bushing 44. A hub 46 is fastened to the bush 44 by means of bolts and rotate together on the drive shaft 42.
  • a gear transmission is mounted eccentrically on the hub 46 with the aid of a pivot pin 50.
  • the pivot pin is secured by a cap screw 52.
  • An internal drive 54 is mounted on a pair of support rods 56.
  • the inner drive has teeth 58 which engage the outer teeth of a gear transmission 48.
  • a drive arm 60 is rotatably supported on the front side of the gear transmission 48, as shown in FIG.
  • the drive arm 60 is carried along with the gear by the gear transmission 48 driven by the wheel hub 46 around the inner race 58. Since the gear mechanism rotates around the inner drive, the axis 62 of the drive arm 60 serving as the fulcrum also describes a circle.
  • the end of the drive arm 60 is attached to the connecting rod 66 with a pin 64.
  • the other end of the connecting rod is attached to a carriage arm 68 and a carriage 70, the connection being made by a guide pin 72.
  • the gripper bar itself is provided with the reference symbol 74.
  • the gripper bar contains a plurality of spring-inclined, rotatably mounted gripper fingers 80. One end of the finger carries one cam 82 while the other End abuts against a support rod 84.
  • the support rod 84 and the gripper slide rod 76 are connected to the slide arm 68 by a joint 86.
  • a link lever 88 moves towards the gripper fingers and acts on a cam actuator 90 by means of a gripper cam 82.
  • the finger 80 rotates around its holder until it does the cam opener is pulled away again, whereupon the finger is pulled back by the spring.
  • the book is then held between the finger and the support bar 84.
  • FIGS 3 to 5 show a possibility for damping the supply chain.
  • the feed chain 12 is driven by a main drive gear 92.
  • the feed chain rotates around upper and lower head support gears 94 and 96 and upper and lower idler gears 98 and 100.
  • the idler gears are mounted on arms 102 in series are arranged on an adjustable post 104. The post allows the tension of the feed chain 12 to be regulated.
  • the forward movement of the feed chain 12 is supported by an upper bar 106.
  • the ledge 106 is supported on a series of support arms 108, one of which is shown.
  • the supply chain is supported by a head end bar 110 on its underside and on the upper side by a head end saddle track 112.
  • These components can be mounted on a suitable bracket.
  • An end saddle track 114 and an end guide strip 116 are also provided at the other end of the conveyor.
  • a return saddle track 118 supports the underside of the conveyor when the conveyor returns.
  • a return guide bar 120 extends essentially over the entire length between the lower headrest support gear 96 and the lower deflection gear 100.
  • the links of the feed chain itself are shown at reference number 122.
  • the links carry a plurality of support links 124 on which the printed sheets are placed.
  • the upper guide bar 106 extends between the parts of the links 122 to support the chain.
  • the return is the return saddle track 118, which is usually made of wood.
  • very short chain guides were used for the lower run of the chain. These guides are of a similar design to the return bar 120 in that these two types of guides extend between the protruding parts of the chain links, as shown in FIG.
  • the purpose of these guides is only to ensure that the chain does not ver wraps or knots when it runs from one pocket insert to the next.
  • the known guides are short, interrupted and not suitable for damping chain vibrations. In the invention, continuous strips are used which run essentially along the entire return of the conveyor.
  • the lower run of the chain is guided by the return guide bar 120 in such a way that an oscillatory movement is neither possible to the side nor vertically. This also substantially prevents longitudinal movements from being produced in the forward running of the chain.
  • the lower run of the chain can only vibrate if it picks up some of the hanging end of the forward run of the chain. When this drooping end is picked up, there is longitudinal vibration when running forward. With a long chain drive there is a relatively large amount of play due to the necessary looseness of the pins and links. Due to the guidance in the lower barrel, the vibration is therefore reduced and thus also in the upper barrel. However, this means that unwanted vibrations in the upper run of the conveyor are prevented.
  • the guide bars 110 and 116 also have a constriction for the chain and the underflow vibration is further reduced.
  • the final gear drive is provided with the reference symbol 38. It has a manual transmission 126 which is mounted on the bottom surface 128 of the machine and is connected to the main drive shaft 36 by a coupling 130. A gear 132 is mounted on the output shaft of the manual transmission. A drive gear 134 is keyed onto a common shaft 136 on which the lower deflection gear 100 is arranged. A chain 138 connects gear 134 with gear 132.
  • the continuous constraint on the feed conveyor return may be sufficient to solve the vibration problems.
  • the source of vibration is essentially in the feed conveyor or the oscillating linear movement in the stapling machine together with the corresponding drive. It has now surprisingly been found that this source of vibration can essentially be switched off by attaching a flywheel to the main drive shaft at the height of the starting point for the reciprocal drive mechanism.
  • FIG. 6 shows the arrangement of a flywheel 40 on the main drive shaft 36.
  • the flywheel also couples two sections of the main drive shaft to one another.
  • the right part of the shaft extends up to the gripper bar drive 22.
  • the shaft is supported in a bearing 140 which is fastened to a cantilever plate 142.
  • the left part of the drive shaft has first drive devices which take the shaft with it to drive the stapler heads.
  • the drive devices are provided in the form of a gear 144.
  • This part of the shaft is supported on a bearing 146 which is attached to an upstanding portion 148 of the stapler frame.
  • the weight of the flywheel was determined to be approximately 154 kg in order to significantly reduce the vibrations in the feed conveyor.
