FR2583548A1 - METHOD AND DEVICE FOR AUTOMATICALLY COUNTING, BY TYPE OF WORKPIECES, PIECES OF DIVERSE TYPES CUT SUCCESSIVELY ON THE SAME PRESS AND DEVICE FOR THE AUTOMATIC CLASSIFICATION OF SAID PIECES BY TYPE - Google Patents

Abstract

1. A method for automatically counting, per type of pieces, pieces of various types cut out successively on the same press, characterized in that a transmitter transmits during each cutting operation of a piece a coded transmission characteristic of the type of the cut-out piece, and in that the receiver-decoder controls, as a function of the signal code, one amongst several counters for counting the number of received coded transmissions corresponding to said type.

Description

Method and device for automatic counting, by

  type of parts, parts of various types cut out succes-

  on the same press and device for the classification

  automatic said parts by type.

  The present invention relates more particularly to the counting of cut pieces with die cutters placed under a press, in particular pieces cut from skins.

  at the stage of cutting in the manufacture of shoes.

  The invention is however applicable to similar operations in which different parts are manufactured with various tools implemented in a random manner

in time.

  The problem is all the more complex that, in the process of cutting the skins, the cutters are set up, depending on the appreciation of the cutter, in various locations under the press plate to cut selected locations skin placed under said tray. In addition, the cutters have, in practice, two cutting edges on their two opposite edges, one or the other edge being used according to whether one cuts a part for a shoe.

left foot or right foot.

  In the current practice, the cutter must group together parts of the same model and count them, which may require up to 20% of the working time and this time is, in addition to a waste of time for a highly qualified professional, a dead time in the use of the cutting installation. In addition, the cut pieces must be grouped together

manually before counting.

  The object of the present invention is to remedy these drawbacks and to provide a method for automatic counting,

  by type of parts, various pieces of typE various cutouts succes-

  on the same press according to which a characteristic coded transmission is emitted during each cutting of a part

  the type of part cut and counts, by means of a receiver-

  decoder, the number of coded transmissions received corresponding to

audit type.

  According to another characteristic of the method, a cut code is used on each cut piece to sort

  later cut pieces according to their type.

  The present invention also relates to a device

  for carrying out the method, this device being characterized

  in that each punch is provided with a micro-

  non-directional transmitter whose encoded transmission is controlled by pressing the press on the punch, the device further comprising a receiver tuned to the frequency of the micro-transmitters with a decoder commander, according to the code of the signal, meters connected to a

  display device of their contents.

  Since during a cutting operation of a series of pieces in a skin or a series of skins, a limited number of die punches are used, the micro-transmitters assigned to a press and receiver associated therewith, are provided in number equal to the maximum number of punch used during the operation and they are mounted removably on the punch. The micro-transmitters and the receiver preferably operate in frequency modulation. It is possible, in the case of simultaneous work in the same room of several presses, to associate a control receiver with the transmitter as well as a

  transmitter to the receiver so as to ensure the acqui-

messages.

  The counters and the display device can be of any known type and operate according to the addition and / or counting system with display of the number of parts to be produced in each type and / or the number of parts produced and / or

  the number of pieces remaining to be made.

  Because the counting of the parts made in each type is done automatically, it is no longer necessary to group them by type to perform the counting and the parts can be evacuated in bulk. It is possible to have sorting done by a non-specialized labor force but we can also take advantage of the cutting operation to identify

  parts for sorting and / or automatic feeding

  machines or workers to ensure their

subsequent work.

  To do this and according to the invention, the punch simultaneously applies a code on the cut piece to the cut. This code can be a bar code printed or affixed in any other way. The printed code can be a specific code of the micro-transmitter when it is used only for sorting at the output of the cutting press but it can be a specific code of the part when sorting is performed

  in bulk on the production of several presses or when

  the code is used at a later stage of production.

  According to another characteristic and the pieces of the various types having various shapes and being produced with random orientations, the identification code which is placed substantially at the geometric center of the piece also forms an orientation mark and the sorter comprises, at the entry of the conveyor leading to the various storage stations, a member for refocusing and reorientation of the part so that all the codes circulate under the code readers controlling the doors or sorting members with

the same orientation.
