Definitions

  • the invention relates to a device for the transverse cutting of strips, in particular metal strips, which cuts into the strip with a cutting device which cuts into the strip at intervals which determine the length of the strip section in each case, with a spacing in the conveying direction of the strip the cutting device, which drives the belt to the cutting device, and is equipped with a transport device, which is arranged behind the cutting device in the conveying direction of the belt and transports the strip sections separated by the cutting device.
  • Devices of this type are used, for example, in the processing of rolled steel or light metal strips in order to separate sheet metal blanks from the respective strip.
  • the boards obtained in this way are then passed on for further processing.
  • the strip to be cut is usually conveyed continuously to the cutting device.
  • the necessary distance between the cutting device and the driver device must be bridged.
  • the one that takes over the respectively sectioned strip section and, for example, into one Storage or a further processing station transporting transport device is usually also unavoidably arranged at a certain distance behind the cutting device.
  • the object of the invention is, based on the above-described prior art, to provide a powerful device for cross-cutting with simple means, in which the trouble-free division and removal of the sheet metal blanks is ensured.
  • a device is provided in a device of the type specified at the outset, which can be moved from a waiting position remote from the cutting area of the cutting device and assigned to the conveying device into a supporting position arranged near the transport device.
  • the support device assumes a waiting position during the cutting process, in which it does not hinder the division of the respective sheet metal blank.
  • the support device is moved from the waiting position into a support position advanced in the conveying direction of the belt. In this position it secures the beginning of the belt section to be cut off in such a way that its trouble-free transition to the transport device is guaranteed even if the belt is continuously conveyed on.
  • the invention thus enables the safe operation of a cross-cutting device continuously supplied with the strip to be cut without affecting the strip transport or having to take costly other measures to control the production process.
  • a particularly advantageous embodiment of a device according to the invention is characterized in that the movement of the support device from the waiting position into the support position and back is forcibly coupled to the movement of the cutting device via a mechanical coupling device.
  • a forced coupling can be implemented inexpensively on the one hand with particularly simple means and with little outlay on equipment.
  • the means required for the mechanical coupling are not susceptible to malfunction and do not require any additional hydraulic or pneumatically transmitted energy.
  • the invention can be used particularly advantageously in connection with cross-section devices in which the cutting device has a pair of knives, one of which is assigned to one of the surfaces of the strip.
  • the knives perform a lifting movement directed essentially perpendicular to the belt, the problem solved by the invention of securely bridging one between the cutting device and the respective upstream or downstream drive or processing devices.
  • a stroke-driven drive of the knives it is also possible to hold the knives of the cutting device on a parallel guide, which are driven by a rotary drive. In this way, the lifting movement required for the cutting process can be achieved in a particularly simple manner. This applies in particular when the knives are each held on a holder which is guided by means of two cranks which are rotatably coupled to them in such a way that the respective knife executes a circular movement during operation.
  • the mechanical coupling between the cutting device and the support device can be realized particularly simply in this connection in that the coupling device comprises a coupling member which is firmly coupled to one of the knives and a gear which converts the movement of the coupling member into a movement of the support device.
  • the coupling device comprises a coupling member which is firmly coupled to one of the knives and a gear which converts the movement of the coupling member into a movement of the support device.
  • the support device has a device for conveying the belt supported by it.
  • This additional conveyor which is designed as part of the support device, can be used in such cases, in which the last section of a belt encompassing the end of the belt is too short for automated conveying out of the cross-section device, even without such a short section Need for intervention, which is usually dangerous To transport operators out of the device.
  • Belt conveyors are particularly suitable for this purpose.
  • at least one friction shaft extending transversely to the conveying direction can also be used, on which the belt rests, so that it is driven forward when the shaft rotates.

  • the device 1 shown in FIGS. 1 to 3 for the transverse division of a steel or light metal uncoiled by a device, not shown existing belt B comprises a driver device 2 which conveys the belt B in the conveying direction F to a cutting device 3.
  • the driver device 2 has two drive rollers 5, 6, via which the belt B is driven.
  • a transport device 4 designed as a belt conveyor is arranged behind the cutting device 3.
  • the cutting device 3 has two knives 7, 8 which extend over the width of the band B to be cut and are each carried by a knife bar 9, 10 which also extends over the width of the band B.
  • the cutter bars 9, 10 are arranged in the lateral direction of the conveying path of the belt B, here guides 11, not shown in detail in the vertical direction.
  • the cutter bars can also be cyclically moved from the cutting position shown in FIG. 1 to the starting position shown in FIGS. 2 and 3, in which they are in a position removed from the belt B, by means of lifting devices, also not shown.
  • a coupling member 12 is fixedly connected to the cutter bar 10 assigned to the underside of the band B and engages with its free end in a receptacle 13 of a slide 14 movable axially parallel to the cutter bar 10 in a guide. With each stroke of the lower cutter bar 10, the slide 14 accordingly carries out a stroke.
  • the slide 14 With its end assigned to the band B, the slide 14 is coupled to a mechanically operating gear 15, which converts the essentially vertical movement of the slide 14 into a horizontal, parallel one Movement of a support device 16 aligned to the conveyor path of the belt B is implemented.
  • the support device 16 is slidably mounted in a guide 17 carried by the driver device 2 so that it can be moved from its waiting position shown in FIG. 1 to the support position shown in FIGS. 2 and 3, in which its front end in the conveying direction F. protrudes through the cutting area of the cutting device 3 to the transport device 4.
  • the support device 16 is table-shaped in the manner of a plate and extends over the width of the belt B. At the same time, its length, measured in the conveying direction F, is dimensioned such that, in its waiting position, the distance A between the driver device 2 and the entrance area of the cutting device 3 bridged.
  • the side of the support device 16 assigned to the driver device 2 is bevelled in such a way that this side in the waiting position of the support device 16 in the immediate vicinity of the lower drive roller 6 of the drive device 2 can be arranged.

  • the belt B lies on the part of the belt conveyor 18 arranged on the upper side of the support device 16 on its way to the cutting device 3.
  • the cutter bars 9, 10 are moved towards one another until the are carried by them, horizontally offset from each other positioned knife 7,8 and the band B located between them is sheared.
  • the support device 16 is in its waiting position next to the driver device 2, into which it has been moved along with the movement of the cutter bar 10 due to the coupling mechanically forced by the gear 15, the slide 14 and the coupling member 12.
  • the strip section Ba separated by the cutting process is transported by the transport device 4 to a storage unit (not shown) (FIG. 1).
  • the support device 16 is moved in the direction of the cutter device 3 due to its positive coupling with the cutter bar 10.
  • the end of the support device 16 assigned to the cutting device 3 only reaches the cutting area after the lower cutter bar 10 has moved sufficiently far from the belt B. In this way, the support device 16 is advanced without interference through the cutting area until the end in question is arranged near the transport device 4.
  • the belt B is continuously conveyed further by the driver device 2.
  • the support device positioned near the transport device 4 ensures that, in particular, the beginning Bb of the new belt section to be separated is reliably guided onto the transport device 4 (FIG. 2).
