  SYSTEM FOR CUTTING AND / OR PLACING SHEETS OF

PAPER AND / OR CARTONS

  The present invention relates to a system for cutting and / or to set up sheets of paper and / or cartons, especially in the context of folding operations during the manufacture of folders. During shirtmaking operations, it is common

  inserted in the latter a sheet of paper and / or a card

tone, to facilitate their folding.

  Systems of known type, allowing a continuous execution of this operation. can only work satisfactorily with cardboard. The use of sheets of paper, alone or with cardboard,

  presents great difficulties, particularly as regards

  identify the removal of leaves from a pile and their placement

  on the shirts. On the other hand, even when appropriate means

  In order to perform these operations, it is necessary to provide bundles of paper sheets of different sizes, depending on the sizes.

  shirts that we will have to fold.

  The present invention proposes to eliminate the disadvantages set out below.

  above, by creating a system for cutting and

  this automatically sheets of paper and / or cartons on the

  updates. More particularly, the present invention proposes to provide a system that can use paper rolls, so as to allow the cutting of leaves having the desired dimensions, and provided with means

  positioning and retaining by the collar of the shirts.

  The system is simple in structure and has a high operational safety

  tioning. The system according to the present invention is characterized in that it is

  consisting essentially of two jigs placed side by side and

  both each retaining means and positioning shirts.

  At one of the ends along the longitudinal axis of the jigs is placed

  a continuous training band, allowing the unfolding and the

  dragging a sheet of paper from a roll. A mobile cart located above the training belt supports a cutting machine

leaves.

  The sheet of paper, cut to the desired size by the cutter, and / or cardboard, provided by the feed unit is put on the shirt by means of a clamp system, the folder having been

  preliminary arranged and fixed on. one of the templates.

  The advantages of the system according to the present invention will be better understood.

  - Figure 11 is a schematic representation of the cutter.

  In referring more particularly to Figure 3, the system according to

  The present invention comprises two jigs (1 and 2) mounted on a platform

  form (3), which can perform successive rotations of 1800

according to a horizontal plane. -

  Referring more particularly to FIGS. 1 and 4, a structure (4) placed at one of the ends of the jigs (1 and 2) supports a continuous drive band (5) arranged in such a way as to allow unwinding and driving a sheet of paper (6) from a roll (6 ') in the direction of the templates (1 and 2). A carriage (7) is located above the structure (4) and slides in two lateral guide rails (8) placed along said structure (4). The carriage (7) comprises a cutter movable along said carriage

  (7) formed of a disk blade (9) and a stationary fixed blade (10);

  placed on the opposite side to the jigs.

  Referring more particularly to Figures 2 and 5, a unit (11) for feeding the cardboard system is placed on the side of the structure (4). The unit (11) essentially comprises a tray (12) receiving a stack (13) of cartons having the desired dimensions. The stack (13) can be moved up and down and vice versa by means of a

cylinder (14).

  Referring also to FIG. 1, a carriage (15) provided with

  its (16) is disposed above the unit (11) o The carriage (15) can be

  move along a horizontal guide rail (17) placed perpendicularly

  relative to the templates (1 and 2) -4 - Referring more particularly to Figures 1 to 4, a plate (18) placed at the end of the structure (4) located on the template side is engaged in a rail of horizontal guide (19) arranged in the middle and

  above the jigs (1 and 2), parallel to their longitudinal axis.

  Referring also to Figures 6 and 10, the plate (18) comprises a set of clamps (20) consisting essentially of two brackets (21 and 22), one of which is fixed, and the second movable and can be adjusted from below on the first, whose horizontal arm undergoes the

pressure of a journal (23).

  Referring now and more particularly to Figures 7, 8 and 9, the templates (1 and 2) of which only one of them is shown here, are provided with means for positioning and retaining by the

  collar the shirts. A fixed block (24) of suitable shape is

  correspondence of a curved element (25). A first cylinder (26) is used to bring the curved element (25) against the fixed block (24). A pin (27) is placed against the fixed block (24) on the opposite side with respect to the curved member (25). A second cylinder (28) allows the journal (27) to move relative to the fixed block (24). These means of retaining

  shirts advantageously comprise three sets of the type described above.

  above, arranged radially and symmetrically on a shaft (29) and ef-

  rotating 120 with a gear wheel associated with a chain (30) actuated by a third cylinder (31) with three positions

fixed.

  Referring more particularly to FIG. 11, the fixed blade (10) of the cutter cooperates with a press-leaf member (33) mounted on a shank (32), which element (33) blocks the sheet of paper while

that she is cut off.

  Referring again and more particularly to FIGS. 1 and 2,

  the roller (6 ') is mounted on a carriage to facilitate the operations

  setting up and replacing the roll in the box.

  provided in the structure (4) below the drive belt (5).

  A practical mode of operation of the system according to the invention will be

  described with reference to all the figures, and assuming the operation

  placed in front of the template (2).

  A shirt is placed on the template (1); the neck of the shirt being engaged around the fixed block (24) and buttoned. The choice of the block among the three available is a function of the width of the neck of the shirt. The curved element (25), actuated by the operator with the aid of a pedal, clamps the neck against the fixed block (24) while the trunnion

  (27), apart from the block (24), stretches said neck in a suitable manner.

  At the same time, the sheet of paper (6) and / or the cardboard (13) are placed in front of the set of clips (20). In particular, in the case where a roll (6 ') of paper is used, the sheet is deployed by the drive band (5). The assembly is automatically stopped by a photocell or similar means when the sheet arrives beneath the clamps (20) in the proper position. To cut the leaves according to the desired length, it suffices to modify the distance existing between the carriage (7), which supports the cutter,

and the set of tongs (20).

  When simultaneously using a sheet of paper (6) with a card

  ton (13), it is taken from the pile on the plate (12) by the suction cups (16). The carriage (15), actuated by means of

  known, then transports the carton (13) on the sheet (6).

  This operation is carried out alone when it is decided to use only

  cardboard. In this case, the drive band (5) is then stopped.

  In a second step, the operator actuates, also by means of a pedal, the set of grippers which seizes an edge of the sheet and / or cardboard to move it and deposit it on the shirt, in the vicinity

collar which will then be cleared.

  Finally, the operator controls, always by means of a pedal, a rotation

  180 of the platform (3), which brings the jig (1) with the shirt prepared in front of him. At the same time, a new operation

can start on the template (2).
