摘要:
An apparatus for inserting tuft assemblies (P) through a mattress (M), with retention disks (D1, D2), comprising a mattress locking structure composed of: two walls (2, 3), flat and parallel with a space for accommodating the mattress for compression; a first carriage (11), supported by one (2) of the walls with a first disk feeder (87a) and a tuft insertion device (10); a second carriage (23), supported by the second wall (3) supporting a second disk feeder (87); an actuator (13-20; 24-31) for the carriages (11, 23); each one of the feeders (87, 87a) for disks (D1, D2) comprises a disk magazine (91) that is supported on a respective carriage (11, 23) and contains disks arranged in stack acted upon by a pusher (93) in order to keep a front disk (D1a, D2a) of the stack in a pick-up position; and pick-up elements each with a transfer element (36, 51, 59, 64), supported by a carriage.
摘要:
A magazine for a plurality of reels (3) of tape (2) provided with a device for selecting a reel of tape to be used, comprising a plurality of supports for the reels, which can slide on a guide (8) so that the reels form a stack whose axis is parallel to the guide, elements (9,13) for actuating simultaneously the plurality of supports along the guide (8) in order to position the reel (3) of tape (2) to be used in a preset point of the guide (8).
摘要:
A machine for packaging a mattress in a sheet, comprising horizontal supporting and receiving mattress surfaces, guides (3,18,19) for guiding the sheet (4) on a vertical plane, so that by moving the mattress in the advancement direction (7) from the supporting surface (1) toward the receiving surface (5) the sheet is arranged over and under the mattress, a device for joining and cutting the sheet upstream of the mattress and for forming a bag which wraps around the mattress, sheet unwinding assemblies (27,28) comprising two rollers (42,42a) movable along the receiving surface with a return stroke, the rollers (42,42a) being articulated to rotate between alignment and parallel positions in which they are perpendicular or parallel to the advancement direction (F) and to the sides of the mattress, and actuators (45,45a) for actuating the rollers (42,42a).
摘要:
A device for positioning and joining at an angle, by means of a sewing machine, the edges of two flaps of fabric (P, F), particularly of a horizontal sheet and of a vertical band for forming a mattress case, said device comprising a first guiding wall (17a) for the edge of the sheet (P) and a second guiding wall (17b) for the edge of the band (F), said walls forming mutually adjacent cylindrical sectors (17, 18), two advancement elements being further provided which comprise rotating heads (6, 7) accommodated within cavities formed by said walls, said walls being movable between a position in which said rotating heads tangentially engage the edges of said sheet and said band on said walls in order to advance said edges toward a sewing region and a position in which said walls allow said heads to disengage from said walls.
摘要:
An apparatus for temporarily storing manufactured items, particularly mattresses, comprising: a framework (2a-4d) for supporting a plurality of horizontal and superimposed frames (8a-8f) for supporting the mattresses to be stored, the framework being provided with guides (6a,6b) for guiding the frames vertically; an actuation system (19a-19d,23,24) for individually actuating the frames between a lowered position, in which they are mutually close so as to form a stack, and a raised position, in which they are mutually spaced by an extent which is greater than the height of the individual mattresses; a platform for receiving a mattress which lies above the upper frame of the stack; transfer elements (31,32) for individually transferring and positioning the mattresses on the receiving platform and for individually removing the mattresses from the receiving platform, the transfer elements (31,32) being synchronized with the actuation system (19a-19d,23,24) for actuating the frames (8a-8f) so that during the storage of the mattresses the upper frame (8f) of the stack is raised until the mattress is brought to a level which, with respect to the receiving platform, is greater than the height of one mattress, while during mattress removal the lowest (2a) of the raised frames is lowered below the receiving platform, so as to deposit the mattress onto the receiving platform.
摘要:
An apparatus for temporarily storing products at the exit of a quilting machine comprising an inclined guiding element (28) along which at least one carriage (33), provided with an element (46, 47) for gripping the product manufactured by the quilting machine, can slide by gravity, a first (54) and a second (55) stop elements for the carriage (33) being arranged along the guiding element, and actuation elements (61), which act on the grip element (46, 47) to release the removed product, being associated with the stop elements (54, 55). The carriage (33) released by the second stop element (55) is transferred onto a vertical lifting unit (14), which is provided with retention and release elements (16, 17) for retaining the carriage (33) at the lower stroke limit and releasing it at the upper stroke limit to insert the carriage (33) on the guiding element (28).
