FR2571987A1 - Automatic transfer machine for performing pre- and post-operative operations to that called flocking - Google Patents

Abstract

The invention consists in automatically transferring components 1, by means of a chain drive 2 supporting the support spindles 3, to the preparation vessel 4, to the flocking chamber 5, to the drying station 6 and to the ejection station 7.

Description

-1- The present invention relates to the flocking operation which consists of

  a deposit of synthetic textile material, cotton, wool, etc., of all deniers and of all lengths, on manufactured parts so that they have a finish appearance identical to a covering by a glued velvet fabric.

  Companies sell devices that allow this app

  cation. It essentially includes: a) 1 special LV / HV transformer b) 2 HT electrodes. A fixed behind the piece to flock and

  the other formed by the nozzle of the projection lance.

  c) 1 lance for spraying the product with compressed air.

  An operator, manually, projects the flock using the lance on the part that he is holding or that he has fixed in a

suction cabin.

  On the other hand, depending on the materials constituting the part (wood, plastic, iron,) of the preparatory manual operations

  are to be executed before flocking. The fixing time / se-

  chage, later requires waiting supports.

  All of these operations ultimately lead to

  flocking at a high labor and cost price.

  Reducing these costs is the object of the present invention.

  It consists of a closed chain with rollers 2 stretched and guided

  dée by the chain sprockets 9 mounted freely on their axis.

  The step-by-step advance of chain 2 is achieved by the

  quet 10 mounted on the cylinder rod 11.

  Following a constant pitch, the support axes 3 of pieces to be flocked are fixed on the chain. The end of the axis is

  split in order to be elastic when interlocking and holding.

  A pinion 12 is pinned on the top of the axle.

  On the lower part of the chassis, two jacks 13 and 15 are fixed, maneuvering in elevation the tanks 14 and 4. The tank 14,

  simple container of cleaning product for the support shaft 3.

  Bac 4 is more sophisticated. It consists of a tank

  for double wall immersion surrounding elements I - II -

  III - to allow the circulation of a heat transfer fluid from outside, cooling or heating the product

of preparation.

  The cells I - I - - II - are sealed together by

2571987-

  -2- a partition, but can be placed in communication with one another by the hydraulic connection 16 actuated by the tap 17. This blister gives the following three advantages: a) for a short time cycle, to have 1 time, 2 times or 3 times, the cycle time in preparation time with 17 open b) The taps 17 closed allow 1 to 3 different products. c) to limit the sloshing of liquids

  The so-called drip tray IV is independent of the three

  very. A flexible pipe 18 connects it from its bottom to a jerry can 28

  placed on the ground. Thus it remains empty of the drip received.

  - The cylindrical-conical flocking chamber 5 is

  open at both ends. From side 8, a corrugated pipe under-

  ple allows the aspiration of the unregistered flock to a vacuum bag

so-called "recycling" cuperation.

  The support collar 19 receives the flocking lance.

  The fixed flocking electrode 20 is fixed in the axis of

  5 on the large diameter of the trunk.

  To cover the part to be flocked at this station, the chamber 5 moves by rotation on the axis 22, under the action of the jack. At the end of the movement, the passage opening 23 is

closed by sheet 24.

  The jacks 25 and 26, each coupled respectively to a rack 27 allow each cycle by meshing on the pinions 12, to rotate the support axes 3 by

draining and flocking.

  The flocked parts are then dried in the tunnel 6, before being ejected into a basket by the ejector 29

mounted on cylinder 7.

  A group of resistors 30 in series with a motor-driven fan

  reader 31, blow into tunnel 6.

  This machine therefore allows a single operator to execute

  ter flocking and all pre- and post-operative operations

  res to this work in a very short time.

  Each movement can be executed individually for adjustment. In automatic, the operator only takes care of loading -3-

  at stations located between bins 14 and 4.

  Also after pressing the "start cycle" button, the movements and operations are executed in the following order: - Advance transfer of parts by one step by 11/10 - Rise of tanks 14 and 4 - Displacement of room 5 towards the part - Ejection of a flocked part

  - During the elevation of tray 4, in cell IV the part

  drop by centrifugation - Chamber 5 in the working position controls the rotation of the part, the flocking lance walking continuously

  - During all these operations, the jack 11 returned to po-

  high position, and the operator has loaded a single upper axis

  Harbor. When the automation which monitors, commands and controls the operations, judges a possible new transfer, orders the advance of a step. The cycles can be between 7 and

seconds.
