Definitions

  • the invention relates to a device for separating single-layer or multi-layer continuous form sets or the like provided with transverse perforations, with a tear-off arrangement comprising two transporters which are arranged at a distance from one another in the transport path of the set and which are possibly formed by the set of transport roller pairs between them. wherein the forward conveyor in the transport direction is drivable at a higher speed than the rear conveyor in order to generate a tensile stress which causes the tearing of one of the transverse perforations in the section of the set located between the conveyors.
  • the two transporters each run at a constant speed, the front transporter running faster than the rear one.
  • the front transporter running faster than the rear one.
  • the front piece of the set is torn off by the front carrier transported at a comparatively higher speed to a storage, whereas the following leading end of the continuous form set is moved to the front carrier at the lower speed.
  • a tension builds up again in the block, which ultimately leads to the next block being torn off.
  • the distance between the two carriers must be matched to the selected length of the sentence to be separated; the distance usually corresponds to this length. This is because at a smaller distance the tensile stress builds up too early and the set breaks off too early, possibly due to an intermediate transverse perforation.
  • the transporters can optionally be driven at the same and different speeds.
  • the transporters which may be arranged at a relatively small distance from one another, are driven at the same speed until the transverse perforation to be separated reaches the transporter area.
  • both transporters are driven at different speeds, namely the front transporter at a higher speed than the rear transporter.
  • tensile stress builds up in the section of the set between the conveyors, which ultimately leads to the tearing of the set along the previously defined transverse perforation.
  • both transporters can be driven again at the same speed until the cross perforation to be separated comes into the area of the transporters etc.
  • sentences of very different lengths can be separated with one and the same conveyor arrangement.
  • the small distance between the two transporters results in an advantageously compact design of the device. It is also particularly advantageous that, due to the possible short distance between the transporters, it is ensured that only the transverse perforation to be actually separated is between the transporters during the separation phase, whereas in the known device one or more intermediate transverse perforations are also arranged in this section can, so that it cannot be ruled out in the known device that the wrong transverse perforation tears open.
  • the device according to the invention therefore guarantees a reliable separation function at the predetermined point in the set.
  • a control device for receiving information about the length of the sentences to be separated and for issuing speed command signals to the front and / or rear transporter.
  • An automatic synchronization of the device with the run of the block is obtained by the device by a first detector for emitting a position signal indicating the exact position of the block to the control device.
  • the first detector is arranged in the area between the perforation tear point and the front conveyor and is designed to measure the passage of the leading end of the set.
  • the detector can be a microswitch, for example; however, a light barrier is preferably used because it works without wear.
  • the length of the parts to be separated is constant. This length is initially entered into the control device.
  • the control device can be connected directly to the data processing system that prints the set of continuous forms. The data processing system then outputs the information mentioned about the length of the sentences to be torn off to the control device from case to case.
  • the device according to the invention for separating continuous form sets can also be operated without a direct connection to the data processing device if a second detector is provided for reading a marking on the set indicating the length of the sentence piece to be torn off next and for delivering a corresponding cut length signal to the control device.
  • Magnetic markings are conceivable or mechanical (e.g. hole patterns) that can be read by appropriate detectors.
  • an optical marker reader is preferred, since the corresponding markings can be printed without great effort when producing the continuous form set.
  • a third detector is provided for measuring the current setting and / or speed of the front and / or rear transporter and for issuing a corresponding setting or Speed signal to the control device.
  • the third detector can be formed by an inductive sensor, which scans a slotted disc or the like running synchronously with the drive shaft of one of the transporters, preferably attached to the drive shaft in a rotationally fixed manner.
  • the lengths of the pieces to be separated are usually given in inches. A sufficiently precise control is obtained when the pitch of the slotted disc corresponds to a transport length of 1/6 inch ( '25 .4 / 6 mm).
  • control device comprises a counter which begins to count the setting signals in response to the position signal and also a comparison circuit which, when a predetermined count of the counter or derived from the cut-off length signal is reached, sends a speed command signal to the cut-off to effect the cut-off delivers front and / or rear carrier.
  • the transporters run optionally at the same speed and at different speeds if, as proposed according to the invention, the two transporters are coupled to one another via two mutually connectable gears with different transmission ratios one with a single drive motor.
  • one of the gears, the first gearing continuously couples both transporters via a freewheel, and that the second gearing can be selectively switched on, preferably by means of a magnetic coupling. Therefore, the control device only has to switch the magnetic coupling on or off to switch between the two transmissions.
  • one of the gears is a 1: 1 gear and the other gear is an approximately 1: 2 gear. Due to the relatively high gear ratio of 1: 2, the predetermined cross perforation is quickly separated. The transport speed can therefore be relatively high.
  • the 1: 1 transmission is the first transmission, the magnetic coupling only needs to be in operation for a short time, namely during the disconnection process.
  • the control device is connected to the magnetic coupling for delivering an activation signal forming the speed command signal to the magnetic coupling.
  • the individual layers of the endless form set are first separated from one another in a separating device and then the individual (endless) layers are separated at their transverse perforations.
  • both steps take place simultaneously in a single arrangement!
  • elongated, preferably band-shaped, separating members are arranged between successive layers of the set and extend in the transport direction between a rear fastening point behind the rear transporter and a front fastening point in front of the front transporter.
  • the multi-layer set is thus moved between the conveyors and is separated there as such along the overlapping transverse perforations of the individual layers; Even before the multi-layer set is fed to the conveyors, however, the individual layers are separated to a certain extent by the separating elements, which extend up to the front conveyor.
  • the individual layers of the leading sentence piece separated after tearing the transverse perforations can therefore be individually further processed without any problems, for example be filed in assigned subjects.
  • At least one of the two transport rollers of each transporter only extends over a portion of the width of the record perpendicular to the transport direction, preferably by dividing it into at least two sub-rollers arranged at a distance from one another and that the separators in the rest of the block width through the transporters.
  • the band-shaped dividers reliably guide the layers of form sets through the transporters if they are spring-loaded and therefore always run straight.
  • separating heads can be provided with prestressing springs for the band-shaped separating elements.
  • the guidance of the layers through the transporters is further improved in that a preferably band-shaped cover member is provided on at least one of the two sides of the set, which extends along the separating members.

  • FIGS. 2 to 5 In the event that continuous form sets 14 'with intermediate layers which can no longer be used later, for example carbon paper intermediate layers 42, are used, the arrangement 44 shown in FIGS. 2 to 5 is preceded by the discharge device 44 already mentioned in connection with FIG. This is explained in more detail in FIG. 6. It consists of two pairs of tractors 208 and 210, spaced apart from one another in the direction of transport A, and strip-shaped baffle plates 212 arranged between the pairs of tractors. Each baffle plate 212 lies between the underside of a printed layer 13 and the top side - a carbon paper intermediate layer 42, forming a 45 ° angle with the transport direction A.
  • Each carbon paper intermediate layer 42 is now wrapped around the front edge 214 of the overlying baffle plate 212 in the transport direction A and is led laterally outwards in the plane of the incoming set 14 'from the set 14'. Subsequently, the intermediate layers 42 are deflected, for example downwards, via deflecting rollers 216 and fed to an auxiliary roller device (not shown). In this way, the carbon paper intermediate layers 42 can be transported continuously of the set 14 'are led out laterally in direction A.
  • the set 14 ' is suspended in the tractors 208 and 210 in such a way that the section located between the two pairs of tractors can be expanded sufficiently by the baffle plates 212.
