Definitions

  • the present invention relates to a machine intended for working sheet or sheet elements for the production of packaging, as defined in the preamble of claim 1.
  • the F sheets are transported individually from one station to another using a system of gripper bars B moved by a train of chains C, the circuit of which forms a closed loop with return from above.
  • a system of gripper bars B moved by a train of chains C, the circuit of which forms a closed loop with return from above.
  • two return systems Rm and Ra for example pulleys of the chain train C.
  • a first return system Rm is located upstream (relative to the direction of travel of the sheets), that is to say between the upper bed Ss of the plate press and the introduction station I.
  • the second return system Ra is located downstream of the machine, that is to say say on the downstream side of the ejection station E.
  • the treadmill Tr is driven by an electric motor different from that of the main motor since there is no need to synchronize its movement perfectly with that of other elements of the various workstations P, E, and R described above.
  • the gripper opening system B1 provided at the place where the front waste Df must be removed from the gripper bar B.
  • Such a gripper opening system B1 comprises at at least one element movable between a first position in which it is outside the space provided for the passage of the clamp bars B and a second position in which it is, when the clamp bars B are at rest, at the inside said passage to act on one of the elements forming each clamp B1 in order to open it.
  • a chain G connects, for example, a drive pulley of the clamp opening system to another pulley provided in the upstream return system Rm (this is shown in Figure 1 in broken lines because the chain G is on the side opposite the conductor). From FIG. 1, it is possible to see that the chain G must extend over a great distance, a distance which is further extended by the fact that its course is not straight but describes a path first horizontal, then vertical , so as not to obstruct access and visibility to the different workstations.
  • the linear speed of movement of the chain can be very high.
  • the fact of having to locate the treadmill Tr in the upper part of the reception station R prevents having easy access and sufficient visibility to this station, this especially on the side opposite to the driver, that is to say say at the rear or below the exit end of the treadmill Tr where slides are generally arranged to guide the front waste Df towards the waste container D placed at the bottom of the ejection station E.
  • This lack of visibility and access and also of available space are particularly troublesome when the reception station R is associated with the operation known as separation of the poses - or sides - by means of two mobile frames, one of which is located below and the other above the chain train C.
  • each front waste Df is removed from the clamp at the place where the chain train C begins to descend downwards in the direction of the upstream return pulley Rm. This place has been chosen because it allows to make the most of the space available by a judicious arrangement of the elements intended for the disposal of frontal waste.
  • Such a clamp bar B generally consists of a hollow section B4 on which are mounted, transversely offset, several clamps each consisting of an elastic blade B2 and a fixed clamp B3.
  • the opening of each clamp is carried out by pushing down the blade B2 by means of a pusher 10 in the form of a punch, the end of which is provided with an adyprene element 11 to reduce noise and wear.
  • Each pusher 10 passes through a corresponding opening of the counter-clamp B3 and is fixed to a first profile 12 extending parallel to the clamp bar B.
  • Each longitudinal end of the profile 12 is fixed to the first end of a first tilting lever 13, the other end of which is fixed to a shaft 14 mounted at its ends on the frame of the machine and which can be driven in rotation.
  • the device intended to move the front waste Df away from the clamps B2, B3 also consists of a second profile 20, one side of which, seen in profile, is provided with an extension 21 bent downwards. Seen from the front, this extension 21 has the shape of a rake between the teeth from which the clamps B2, B3 can take place.
  • the interior of each end of the second section 20 is engaged with a block 22 mounted in free rotation on the first end of a second rocking lever 23 whose other end is locked on a drive shaft 24.
  • the rake 21 can really fulfill its role which consists in pushing the waste Df out of the space between each clamp B2 and counter-clamp B3, it is necessary to give to the free end 210 of the rake which comes into contact with the waste Df, a rotational movement.
  • a rotational movement To obtain this movement, it appeared advantageous to associate the rotation of the second profile 20, relative to the second lever 23, with the tilting of the first lever 13.
  • each block 22 of the second profile 20 is linked by a link 30 to the first tilting lever 13.
  • Two tensioned springs 300 one end of each of which is fixed to the frame of the machine and the other end to a rocking lever 13 tend to bring these two levers 13 into a position such that the rake 21 and the pushers 10 are out of the way of the clamp bars B.
  • Such a location for the means for discharging the frontal waste is, of course, also possible in a press with a movable upper bed base and a fixed lower bed base.
  • the evacuation means will be fixed directly to the side frames of the machine.
