- the invention relates to a process for manufacturing, installing and installing elements produced by following the successive steps. following:
- the step of liquefying the face opposite to the marked face is carried out by adding molten hot-melt material.
- the molten hot-melt material is the same as that of the element;
- a final step consists in placing another piece on the marked face of the element secured to the previous piece.
- the invention also relates to an installation of the type comprising a barrel emptying device receiving a tank of hot-melt product, said tank being connected to a volumetric spray gun for laying hot-melt material in the at least one imprint of a mold, the installation comprising at least one marking means coming into contact with the material in the imprint, a cooling means and a transfer means for removing the element in order to bring it to the station of the liquid side.
- the installation comprises a means, in particular a nozzle for depositing on said element cooled with a drop of liquid hot-melt product, said means for depositing connected to the barrel emitter being located upstream of the volumetric gun.
- the invention also relates to a device according to which the mold comprises at least a second imprint in the form of a bar making it possible to manufacture bars of hot-melt product intended to supply a manual gun for placing liquid product on one side of the 'element.
- the mold and the cooling means are constituted by a rotary table comprising cavities arranged along a trajectory circular, the table comprising means for advancing in stepwise rotation corresponding to the spacing of each imprint, the marking means consisting of the shape of the bottom of the imprint or the shape of the surface of a pusher coming form
- the transfer means is a suction cup.
- FIG. 1 schematically shows in vertical section a manufacturing installation for installing and installing wedging elements according to the invention and the manufacturing devices.
- FIG. 1 schematically represents in vertical section, the devices for setting up and placing an installation according to the invention supplementing FIG. 1.
- - Fig. 3 shows in top view, the indexing table according to FIGS. 1 and 2.
- - Figs. 4, 5 and 6 are partial schematic sectional views illustrating phases of shaping of the wedging elements.
- - Fig. 7 schematically represents an installation part according to the invention allowing the manufacture of wedging elements for manual laying seen in vertical section.
- Fig. 8 shows a gun for manual installation of the liquid face.
- FIG. 9 shows a variant of a device for manufacturing an installation according to the invention.
- FIG. 10 shows a variant of the step of the method for producing the liquid face.
- the installation shown in FIG. 1 includes a barrel emptying device 1.
- This device 1 comprises a chassis 2 on which a tank or barrel 3 filled is placed of hot-melt product 4, a pumping group 5 is arranged above the barrel 3.
- Cylinders 66 adjust the pumping group 5 according to the level of the surface of the hot-melt product 4 contained in the barrel 5.
- the pumping group 5 is connected by a pipe 6 to a gear gun 7 for distributing the hot product, that is to say in liquid form.
- the gun 7 comprises a housing 8 delimited by six flat walls 9.
- a wall has a supply opening 10; the facing wall has an outlet 11 opening into a nozzle 12.
- An electric motor 13 controlled by an electronic variator is fixed to a wall 9.
- the nozzle 12 and the motor 13 are positioned on the housing 8 by means of a heating support element 14.
- the piping 6 for supplying hot-melt product 4 is linked to the supply opening 10.
- a pipe 15 connects the outlet orifice 11 at the nozzle 12.
- Two pressure taps 16, 17 are mounted respectively at the feed opening 10 and at the pipe outlet 15 in the nozzle 12.
- the nozzle 12 comprises an extrusion orifice 18 hollow conical sealable by a rod 19 forming a valve and integral with a pneumatic actuating cylinder 20.
- the housing 8 contains a gear formed by two pinions 21 and 22. The pinions 21 and 22 parallel to each other are mounted perpendicular to the orifice of exit 11.
- the gun 7 supplies product with an indexing table 23.
- the table 23 includes indentations 24 for molding and a cooling means 25.
- the table 23 which includes a device 26 for setting in motion step by step is circular as shown Fig. 3 and the imprints 24 are arranged near the edge along a circular trajectory.
- a pusher 27 makes it possible to form the imprints 2.
- the gun 7, the pusher 27 and the gripper 28, all being movable relative to the surface 29 of the table 23, are arranged above the path of the imprints 24.
- the installation according to the invention also comprises a gripper 28 with suction cups 29 by air suction 30, as shown in FIG. 2.
- the gripper 28 is manipulated by a robot 31 to an articulated mechanism 32 comprising a plate 33 for receiving the element 34.
- the articulated plate 32 being placed under an extrusion nozzle 35 connected to the piping 6.
- a jack 36 pushes mechanism 32 to glass volumes stacked on a pallet 38.
- the operation of the installation is as follows, the product 4 is pumped into the barrel 3 by the pumping unit 5 which supplies the gun 7 through the conduit 6.
- the product 4 is driven towards the extrusion orifice 18 by the rotation of the pinions 21, 22 of the gear.
- the pinions 21, 22 are driven and controlled in rotation by the motor, so the motor controls the flow.
- the robot 31 gives the authorization to start the engine and to open the nozzle when the gun 7 is in the working position above an imprint 24, the product flows at a regulated flow rate, which allows to obtain repetitive filling of an imprint.
- the indexing table 23 rotates one step so as to bring the impression 24 which has just been filled under the pusher 27 and the following impression under the gun 7.
- the pusher 27 the bearing face of which can be marked, descends as shown in FIG. 4.
- This pusher descends to the level of the impression or in the impression 24 shown in FIG. 5.
- the pusher withdraws and the hot element 39 shown in FIG. 6, is formed.
- the cycle ends with the closure of the nozzle and the simultaneous stop of the motor controlled by the robot and the table.
- the cooled elements are taken out of the impressions 24 by the gripper 28 and brought to the nozzle 35 for depositing liquid product on the smooth face of the element 34; then the jack 36 pushes until the liquid face sticks the element 34 on the glass volumes.
- the robot 31 positions and moves the gripper 28, the pusher 27 and the nozzle 35.
- the bottom of the imprint 24 is marked in low relief and the pusher is smooth.
- the barrel emptying device comprises a fixed pumping group 5 and a movable barrel placed on a elevating chair in accordance with the German utility model G 9420028.9 in the name of the
- FIG. 7 differs from that of FIGS. 1 and 2 in that it does not include an automatic nozzle for depositing liquid product 4 on the elements 34, nor means for automatic transfer of these elements to the volumes 37.
- the table 23 includes a very deep circular imprint 40 so as to form a bar of hot-melt product.
- the installation in FIG. 7 comprises a box 41 which the robot fills with elements 34.
- FIG. 8 shows a known glue gun 42. The bar from the imprint 40 is introduced into the glue gun 42, which allows the liquid face to be deposited on the elements 34 by melting the end of the bar.
- Fig. 9 shows another variant of an installation for manufacturing elements according to the method of the invention.
- This installation comprises a barrel 3 of hot-melt product 4 pumped by a pumping group 5 in a pipe 6 which fills the metal cooling tube 43, the outlet of which emerges under the stroke 44 of a serrated knife 45 so as to cut out product pellets 4 to form the elements 39 according to the invention.
- Fig. 10 shows a variant of the step of producing the liquid face of the element 34.
- the element 34 is brought close to a heat source 46 whose radiation 47 melts the closest face , the element 34 being made of a hot-melt material.
