Description
; The present inven-tion relates to a continuous cycle pressing apparatus, particularly for assembling furniture pieces.
The currently used pressing apparatus for assembling furniture pieces, also called clampers, provide Eor side and upper pressing means, as located above a bench, thereby it is possible to press, on opposing sides, furniture pieces or component parts thereof, of prismatic shape, to assemble the furniture piece.
These known apparatus, however, are not able -to provide for a mass production, in that they operate in a discontinuous or batch way and require a constant surveillance and labour by operators, to load and unload the furniture ;~ pieces and drive the several pressing means.
; The main objec-t of the present invention is to provide an apparatus for assembling furniture pieces and component parts thereof which is able to operate in a continuous way, with an au-tomatic loading and unloading of the articles -to be handled, directly on the operating or treating line, thereby reducing at a minimum the operator labour.
Another important object of the invention is to provide a clamper for assembling furniture pieces in which the assembliny pressures are applied in a very efficient and uniform way, thereby obtaining a perfect connecting of the component parts to be assembled.
~ ~ ;
These objects are achieved, in accordance with the invention, by a continuous cycle pressing apparatos which comprises a horizontal conveying belt aLicJned with a making line, .
a fixed bridge frame loca-ted above the conveying belt in -the movement direction thereof, upper pressing means mounted on the upper portion of the bridge frame, side autocentering pressing means mounted on the uprights o~ the bridge frame and able to ~ . .
.
.
transversely reciprocate to locate the side pressing means above the conveying belt during the pressing step and laterally spaced therefrom during the advancing step of the furniture pieces on the conveying belt, after each pressing step, and driving .
members for actuating the upper and side pressing means and for :~
transversely moving the side pressing means.
According to a preerred embodiment, the upper and side pressing means are provided with autocentering pantograph~
: shaped driving arms.
The advantages of the presen-t inven-tion in particular consist in that, by suitably coordinating the movements of the several pressure means, it is possible to carry out a ~:
continuous cycle operation, with automatic loading and unloading ~ ; .
: of the furniture pieces to be made, thereby reducing at a minimum the labour.

horizontal conveying belt l, driven by a motor variator 2 and aligned with the making line, for example downstream of ;~
a continuous type of conveyor 3 advancing the furniture pieces 4 from a preceding ma]cing step towards the assembling station.
At said station a fixed bridge frame is provided above said conveying belt l, generally indicated by the refer-ence number 5, and located in the movement direction of said conveying belt.
More precisely, the bridge frame 5 comprises four vertical uprights 6 supporting horizontal longitudinal members 7 located parallely to the belt l length.
Said horizontal longitudinal members 7 in turn support upper pressing means 8 effective to press on the upper surfaces of the furniture pieces 4 and preferably of ; the pantograph type.
Said upper pressure means 8 are driven by hydraulic cylinder 9 and comprise horizontal rods lO having a T-shaped cross section effective to press, directly or through inter-.
mediate suitable plates, on the upper surfaces of the furniture pieces 4.
Likewise, at the uprights 6, side pressing means ll are provided, also preferably of the pantograph type, effective to opposingly press on the opposing vertical sides of said ` furniture pieces 4.
More precisely two opposed side assemblies ll are provided, driven by hydraulic cylinders 12 and comprising vertical rods 13, effective to press either directly or through suitable intermediate plates, on opposed verticaI surfaces of the furniture pieces 4.
- 3o Each said side assembly ll may be rectilinearly reciprocated, perpendicularly to the advancing direction of the belt l, being support by a slide 14 vertically extending ';) - - 3 ~
.:
, ' and horizontally movable, thereby each assembly 11 may be located in an operative position above the belt 1, or at .
a rest position, laterally with respect to said belt.
The sliding movement of the slides 14 is obtained by means of horizontal guides 15 cantilever-wise supported by the uprights 6, in which small rollers 16 may slide, said rollers being associated to said slides(fig. 4).
Each slide 14 is horizontally moved by a hydraulic cylinder 17, having a horizontal axis and fixed at the uprights ;~ :~
6 and provided with a stem 17a connected to a projection 18 of that same slide.
. At the rest position, the slides 14 flank the conveying belt 1,: thereby the furniture pieces 4 may be freely moved therefrom, as shown in figures 1 and 3.
At the operating position, reached by actuating the hydraulic cylinders 17, said slides are located above the conveying belt 1, in order to locate the pressing assemblies ~ .
11 ovsr the belt t~ act on the furniture pieces.
Obviously, the upper pressing asserrlbly 8 will be , ; 20 suitably offset with respect to the side pressing assernblies, as these latter are in an operating position, thereby present-ing no mutual obstacle during the movement of the pantograph - .
elernents in the pressing step.
The above described clamper operates in the following manner.
- : By maintaining at first the pressing assernblies 8 and 11 at the rest position~ as shown in fig.1, a furniture piece 4 to be assernbled is advanced by means of the conveying ~ .
belt 1 thereby locating said furniture piece substantially . 30 at the center of the bridge frame 5. ~ .

hydraulic cylinders 17 are actuated thereby horizontally )., _ 4 _ :

shifting the slides 14 from the position thereof flanking the belt 1 to a position above said belt.
The hydraulic cylinders 9 and 12 are then operated thereby actuating the pressing assemblies 8 and 11.
More precisely the cylinder 9 causes the horizontal rods 10 of the pressing assembly 8 to lower and press on the uppe~ surface of the furniture piece 4 located on the belt 1, whereas the cylinders 12 cause the vertical rods 13 of the autocentering side assemblies 11 to hori~ontally move and ~ -press, with opposing relationship, the opposed side surface of that same furniture piece 4.
A rational pressing on the horizontal and vertical eurfaces of the furniture piece under processing is thus obtained, said furniture piece being perfectly autocentered and assembled.
Subsequently the hydraulic cylinders 9 and 12 are driven in an opposing direction, thereby freeing the pressed furniture piece 4, and the hydraulic cylinders 17 are then actuated to locate the slides 14 at the rest positions thereof, ~ ;at the sides of the belt 1.
The assembled furniture piece 4 may be then advanced, by again operating the belt 1 to discharge said;furniture ~ piece for a subsequent processiny and simul*aneously to prepare -( ~ a place for a new furniture piece to be assembled.
Thus the apparatus is ready for assembling a new furniture piece 4, in the above described manner.
' The operating cycle is then repeated in a continuous manner and indefinitely by suitably programming the operation of the several moving and pressing members, according to a predetermined sequence.
~ As it should be clear the apparatus according to the ;~
.. ' ;-~ ' present invention allowe for a continuous processing of ., :
furniture pieces moving all along a single processing line, ~ -.
without requesting any manual operation for loading and discharging the furniture pieces at the clamper. ;~
According to a modification of the present inven-tion it is possible to provide for a vertical movement of the side assemblies 13, instead of horizontal, by rising said assemblies from the belt 1, after each operation, thereby freeing the passage on said belt.
With respect to the conveying belt 1, it may be of any type such as of the rolling shutter or carpet type or the like.
Obviously the invention is not limited to the above described embodiments, and several modifications and variations are possible within the scope of the inventi.e concept.
