Definitions

  • the subject of the invention is a device for distributing strips of wound materials with an automatic device for replacing the roll in service.
  • the object of the invention relates to the technical sector of the means for distributing lengths of strips wound on a reel or core (see in particular FR-A-2402613).
  • the invention applies to apparatus for the simultaneous distribution and cutting of paper, wadding and other wiping materials.
  • the apparatus which comprises an operating roller carried by a support and a reserve roller carried by a second support, the two supports being pivotally mounted on a rigid structure, is characterized in that the two roller supports are connected together by an articulated link with play on one side, in order to bring the ends of their rigid arms carrying the rolls of material to be distributed towards each other, and to automatically transfer the roll in reserve to the roll support service which is then ejected; a mechanism articulated on the roll support in use and releasing the roll support in reserve from its locking means when said roll in use is almost completely unwound; the strips of material coming from the two rollers then being distributed simultaneously until the roller in service is exhausted and the support of the roll in reserve automatically resumes its standby position by elastic return and automatic engagement of the locking means, and the support with its roller new, being returned by spring to ensure firm contact of the roller on the drum, without however hampering its rotation.
  • the apparatus comprises a base plate (1) for wall mounting, with an inclined bottom (la) and two lateral sides (1b-1c), the lower part of which has a bearing directly or attached. (2) equipped with a slot (2a) for mounting the freely rotating support means of a drum (3) whose periphery is made rough, in order to drive the free end of the wound material without slipping on a reel resting on the drum.
  • the support means In a known manner, the support means.
  • the drum consist for one side, of a fixed axis (4) successively comprising a threaded surface (4a) with parallel flats, to be engaged without possibility of rotation, in the slot (2a) of a bearing (2), then a smooth bearing (4b) of larger diameter to which a cleat (5) articulated in (6) is applied to a side wall of the drum.
  • the axis (4) has a bearing for the free rotation of the drum, with an eccentric (4c) at the end, suitably oriented and dimensioned to control the pivoting of a blade holder (7) articulated at (8) on the side walls of the drum, in order to periodically obtain the projection of the blade (7a) out of the drum having for this purpose an opening (3a).
  • the drum rotation support means is constituted by an axis (9) one end of which is made integral with the side wall of the drum, while its central part (9a) rotates in a ring (10) with parallel flats or other angular indexing means, engaged in the slot (2a) of the bearing (2).
  • the axis (9) finally has a collar (9b) carrying an eccentric (9c) which is angularly oriented and connected to a spring (11) attached to a lateral side (1b) of the wall plate, to operate the launching of the drum after cutting or separation of the material by the blade (7a), with a view to returning the drum to its initial position with overflow of a new strip of material.
  • an oriented projection (3b) of the side wall deviates (by mounting assembly of the drum) from a shock absorber (12) articulated on the threaded bearing (2a) of the axis (2).
  • the drum is stopped by pressing the cleat (5) on said axis, while by reaction, the drum starts again until the projection (3b) is supported on the shock absorber which collects the force and restores it by its retaining spring (13) attached to a lateral side (1c) of the wall plate.
  • the cleat (5) rocks by gravity, due to its offset articulation, releasing the drum which is thus ready to be again driven by traction on the strip projecting from the material.
  • the device for automatically replacing the roll in service comprises a rigid structure (14) fixed to the wall plate (1) and composed for example of two lateral uprights (14a) and of a crosspiece (14b).
  • the structure In the lower part, located above the drum, the structure carries free rotation at (15), a support (16) rigidly formed by a hinge crosspiece (16a) and two parallel arms (16b). At the free ends of the arms (16b) are fixed crescent-shaped plates (16c), the lower ends of which form cradles (16d) for receiving and freely rotating positioning of the roll of material (R1), this by means of pins (T1) which are formed on end caps (E1) centered in the coil or core for winding the material.
  • the structure (14) carries free rotation at (17), a support (18) rigidly formed of a hinge crosspiece (18a) and two parallel arms (18b).
  • the free ends of the arms form cradles (18c) for receiving and positioning pins (T2) formed on end caps (E2) which are centered in the coil or core of a roll (R2) of material to be distributed.
  • a spring (27) recalls the support (18) in the high position.
  • rollers (R1 and R2) are called respectively “roll in service and” roll in reserve “, because it is the roller (R2), mounted in the upper part, which must automatically replace the roller ( R1) when the latter is almost entirely unwound.
  • the two supports (16 and 18) are connected to each other by a link (19) which is articulated at (20) on an overhanging tab (18d). of the support (18) and adjustable in articulation on a pin (21) fixed on an arm (16b) of the support (16) via an oblong opening (19a) of the link.
  • the arms of the two supports (16 and 18) are precisely dimensioned and spaced apart so that, by the action of the connecting rod (19), the free ends forming the cradles (16d) - (18c) can cross .
  • the distance (x) between the cradles (18c) is greater than the distance (y) between the cradles (16d).
  • the cradles (18c) are oriented and profiled to receive and retain the pins (T2) of the roller (R2) in reserve until, during the transfer of said roller (R2) on the support (16) , the weight of the roller (R2) drives the pins (T2) out of the cradles which then abut against the crescent-shaped plates (16c).
  • the cradles (18c) form on the outside a bead (18th) between the receiving part and the end.
  • the cradles (16d) have a rear spout (16e) shorter than the front spout (16f), in order to allow the trunnions (T2) to pass when the reserve roller must take the place of the roller in service, then to retain it in the receiving part which is separated from the end of the rear spout by a bead (16g).
  • a hook or bolt (23) which comprises for this purpose an active end (23a) intended to retain in the raised position the support (18) having at this location a hooking projection (18h).
  • the lock (23) has an axis (24) on which the end of a connecting rod (25) is freely articulated, the other end of which has an oblong opening (25a) for articulation with play on one of the arms (16b) of the support (16) by a pin (26).
  • the opening (25a) is of such length that when the roll in service is almost fully unwound, the hinge pin (26) between the arm and the connecting rod pulls on said connecting rod to tilt the hook (23) .
  • the connecting rod (25) is preferably made in two parts (25b-25c) to be adjustable in length by a screw-nut system (28) placed at the ends of the parts facing each other, this in order to operate the lifting adjustable support (16) by the rod (25), as will be seen later.
  • a spring (29) attached to the structure constantly recalls the connecting rod (25) in the high position to prevent the latch (23) from tilting under the weight of the connecting rod.
  • the reserve roller (R2) when placed in the cradles (18c), is braked in rotation by an elastic blade (30) fixed on the wall plate (1), in order to prevent it takes place during distribution with the other roller.
  • the roller (R2) must be mounted with the free end of the strip going up behind to be trapped by the blade (30) and be automatically placed on the other strip wound on the drum (3) when the roller (R2) takes the place of the roller (R1) on the support (16).
  • parallel bars (35) fixed on the structure (14) extend above the drum (3), up to the proximity of the cradles (16d).
  • the free ends of the bars are shouldered at (35a) to serve as a stop for the journals (T1 or T2) when the support (16) is raised, releasing the roller in service almost empty, this in order to prevent said roller driven by rotation of the drum, engaging in the back of the drum.
  • said roller is ejected in the direction of the cover where a suitable receptacle (36) receives it for complete the distribution simultaneously with that of the reserve roller which has taken its place in the support (16).
  • an elastic curved blade (37) is provided. passing in front of said cross and going up higher.
  • This blade can also serve, as illustrated, as an attachment point for a flexible rod (38) or equivalent member, intended to apply the end of the wound strip, to the drum and direct it towards the outlet opening made between the inclined plane (1a) and the bottom of the cover (33).
  • a damping block (39) is fixed on the structure (14) opposite a support tab (18i) formed on the support (18), in order to soften the shock, including the noise, produced by the support ( 18) when it has released its roller and it is returned to the hook (23) by its spring (27).
  • a window (40) suitably sized is provided on the cover (33) to quickly display the loading state of the device.
  • the support (18) pivots on its axis (17) by driving with it the connecting rod (19) with the support (16) of the roller in service, which thus causes said support to rise simultaneously (16) by pivoting on its axis (15).
  • the pairs of cradle arms of each support come very close to each other, and the pins (T2) of the roller (R2), by gravity. emerge from their cradles (18c) to abut against the crescent-shaped plates (16c) of the support (16) ( Figure 6).
  • the operating roller (R1) which has been released from the cradles (16d), abuts against the bars (35), as shown by the broken lines in FIG. 6, then the roller (R1) passes under the elastic blade (31) which has just elastically escaped from said roller during its advance, and rolls on the drum (3) to be received in the receptacle (36) of the cover.
  • the roller (R2) has therefore taken the place of the roller (R1) and the free end of its strip (B2) is ready to be wound on the drum above the strip remaining from the roller (R1), either because it was correctly placed at the rear of the device to apply to the drum naturally during the transfer of the roller (R2), or because it is guided by the elastic blade (31) which accompanied the roller (R2) to be placed as close as possible to the drum.
  • a metal part (42) or other rigid material, generally U-shaped, and whose wings (42a) extend above the drum (3) is attached to the base plate (1) substantially. beyond its axis of rotation.
  • the wings (42a) are raised at their vertical ends to form stops (42b) rising up to the level where the two roller holders cross during the transfer of the roll in reserve on the service roller holder.
  • the ends of the wings (42a) thus prevent the almost empty roller in use (R1) from engaging behind the drum.
  • the roll holder (16) is equipped with a spring with flange (43) which is adjustably attached (arrow F) to one end on the base plate (1), for example on a threaded rod (44) between two nuts (45) while the other end is attached to the roller holder (16) at a particular point (16h), so that when the roller (R1) is new the line of action of the spring forms a very flat triangle with the attachment points and the axis ( 15) pivoting of the roll holder (figure 9).
  • the pressure is adjustable by varying the point of attachment of the spring on the rod (44), by displacement of the nuts (45).
  • attempts have also been made to improve security at the level of the lower opening for passage of the strips of material to be pulled.
  • attempts have been made to prevent the user's fingers from being able to engage in the opening which must be wide enough for the strips of the two rollers to pass.
  • a device comprising for example two axes (46) carried by each wing of the base plate of the device, and on which is mounted with free rotation a hollow shaft (47), or a commercial profile tube.
  • This shaft is driven in the same direction as the drum by means of a belt (48) positioned in the appropriate grooves (47a) of the shaft (35) and (3c) of the drum.
  • the shaft (47) rotates in the direction of drum and thereby facilitates passage through the opening.
