Definitions
- the present invention relates to an automated device for holding wooden elements on a pressing table for their assembly
- the farms are made by assembling in a triangle, on a pressing table, two rafters and a beam reinforced by triangulation pieces judiciously arranged.
- the components of the farmhouse are arranged on the pressing table and generally held by sliding sliding stops in grooves of the metal plate of the table and locked by screwing.
- "Connectors" made up of metal claw plates are then inserted at the junction points using mobile jacks carried by a gantry sliding longitudinally above the table.
- the settings and setting of the farms, as well as the control of the pressing by jacks are done by hand.
- the woods are positioned on the table and held by the stops put in place manually; the connectors are then pre-driven using a hammer, then the operator positions the jacks above the connectors and actuates a lever allowing the pressing down said cylinders.
- the disadvantage is that the adjustment operations are manual, the time required is long, resulting in high labor costs, and the equipment used (movable stops, rails) is damaged quickly.
- Patent No. 2,707,546, in the name of Mr. Christian DEBANNE, describes a device making it possible to use a table of any type, allowing unconstrained movements of the holding elements over the entire surface of the plate and minimizing the consequences of failures any chuck or computer system.
- This device uses, for the maintenance of the parts to be assembled, studs consisting of cylindrical blocks fitted in the lower part with spikes sinking into a wooden tray covering the pressing table, these studs being put in place by means of a hollow mobile mandrel provided on its internal face with lugs capable of sliding in "L" grooves provided at the periphery of the studs and arranged so that they can be released or made integral with the mandrel by causing the latter to rotate a fraction of a turn in one direction or the other.
- the device according to the present invention aims to remedy these drawbacks. It allows, in addition to the use of any type of table, to move a series of studs very quickly and has great reliability thanks to the elimination of rotational movements of the stud entry system.
- a pressing table with wooden tray and a mobile gantry comprising a magazine for storing the studs consisting of vertical pins mounted under a rail fixed laterally on the gantry and on which the studs which have a vertical bore can be threaded with spring balls ensuring their maintenance thanks to grooves provided on the pins, a motorized unit sliding on the rail, intended for the installation, removal and storage of the studs, being equipped with a vertically movable clamp having a lateral U-shaped opening capable of being inserted in grooves annulars arranged on the periphery of the studs
- FIG. 1 represents a pressing table seen from above, with a clasp in place
- FIG. 2 shows said table seen at the end, according to arrow A in FIG. 1
- FIG. 3 is an enlargement of detail B in FIG. 2
- FIG. 4 is an axono-metric view on a different scale representing the clamp of the motorized unit near a pin carrying studs
- FIG. 5 shows in axial section a stud the lower end of a pin
- the figures 6 and 7 show, under the same conditions, two variants of pins on which studs are stored.
- FIGS. 1 to 7 The device, FIGS. 1 to 7, is mounted on a pressing table 1 comprising a movable gantry 2 perpendicular to said table and moving longitudinally above it.
- the plate 3 of the pressing table 1 is made of wood, without grooves, and may consist, for example, of a plate of solid wood, plywood or chipboard covering the entire surface of a metal table.
- Pads 4 for holding the parts to be assembled can be fixed in position thanks to spikes 5 arranged at their lower part and sinking into the wood of the tray.
- the mobile gantry 2 comprises one or more jacks 6 of which at least one can move transversely to the longitudinal axis of the table 1. The role of these jacks is to exert a strong pressure from top to bottom in the direction of the plate 3.
- the constituent parts of the farms 7 are arranged on the plate 3, the connectors 8 are pre-inserted manually, then the movable gantry 2 and a jack 6 are moved successively above each connector before d 'actuate said cylinder for final tightening.
- the gantry 2 is laterally equipped with a rail 9 perpendicular to the axis of the pressing table 1, on which slides a motorized unit 10 which can be positioned above any point on the plate 3.
- This motorized unit comprises a rod 11 simple or double, vertically movable and terminated at its lower part by a clamp 12 consisting of a horizontal plate having a lateral opening in the shape of a U determined to be able to be inserted in annular grooves 13 arranged at the periphery of the studs 4.
- This opening comprises an elastic element 14, such as a spring ball, determined to maintain a stud in the clamp 12 while allowing its insertion or extraction by exerting a slight force.
- an elastic element 14 such as a spring ball
- several vertical pins 15 are mounted, each comprising a series of circular grooves 16 distributed over its height. These pins constitute a store for storing the studs 4 which have a vertical bore making it possible to thread them from below on these pins, either manually, either by means of the clamp 12.
- Each stud is provided with an internal spring ball 17 arranged to immobilize it at a determined height by penetrating one of the grooves 16.
- the circular grooves 16 can be replaced by a shoulder 18 disposed at the base of the pins 15.
- the motorized unit 10 is arranged so that the clamp 12 can be positioned facing any stud 4 present on a pin 15 and be inserted into the annular groove 13, using only the horizontal movement of the unit along the rail 9 and the vertical movement of the clamp.
- pins may for example be parallel to each other and fixed along the rail 9, at its lower part ( Figure 3).
- the clamp 12 will bypass the pins located in front of the one on which the stud to be reached is located and will rise along it to the appropriate height.
- the pins 15 are mounted on a rotating barrel, fixed under the rail 9 and the rotation of which will make it possible to present in front of the clamp 12 the pin on which the chosen stud 4 is located.
- This arrangement makes it possible to significantly reduce the amplitude of the translational movements of the gantry 2 in order to modify a configuration of the studs 4, which makes it possible to very significantly reduce the duration of the operations and consequently the manufacturing costs.
- all the pads of one zone are removed and placed on the pins 15 before bringing the gantry over another zone. We proceed in the same way for the establishment of the studs.
- the movements of the mobile gantry 2, the motorized unit 10 and the jacks 6 are controlled by an electronic assembly which can for example be installed in a cabinet mounted on this gantry.
- the data relating to the positions of the pads 4 and of the connectors 8 for a determined series of identical farms 7 are produced on a current computer, using ad hoc software, and transmitted by an appropriate means such as cable or diskette to the electronic assembly. .
- the position of each holding pad 4 is memorized after any movement, which will make it possible to find it and determine the movement to be made for a new subsequent configuration.
