Description

The invention relates to a device for recording messages on a perforated strip, in which holes punched from both sides according to the rotary position of a code disk especially for recording the course of the work in production machines.

There are punch known, the punched tape and punch cards on both sides with the help of two to each other provided information that works according to the "timesharing" principle, to double the feed speed of the punched tape or punch card. However, you have the disadvantage that they can only become a fixed one with considerable technical and economic effort Allow coding (German interpretation document. 128 203). Another known punching device with the same effect, preferably for punch cards, also aims at the general conversion of electrically cingebbarcn, in optically readable information (Swiss patent 355 639).

It is also slower working relative to the above Known punching device which can be operated by hand, the punched tape with a counter setting corresponding coding is punched. This punching device is for coding teeienet. but has the disadvantage that neither fixed code words In the form of code disks, the code disks designed as meter disks are also used (French patent specification 1351785).

To check a workflow afterwards In order to be able to do so, it is necessary to record a sequence of messages, each of which has a specific Characterized the phase of the work flow. If this recording is from a machine, for example to be carried out with a scribe or a strip punch, the. News in In the form of special signals that can operate the recorder. To do this you have to all relevant events and states are converted into such signals during the work process will. If you do not record these messages continuously, but gradually, will one cannot readily obtain information about the occurrences within the time interval between the individual steps. A temporal sampling is however with automatically working Devices are therefore desirable because many processes are carried out easily, for example by a wave of programs or an electronic clock pulse generator can be synchronized. To now be> a step-by-step record of the events that occurred between the. individual cycles take place, to be taken into account, one can combine the events into a "result" during this interval and this result play as a message at the end of the interval. Such a message only makes sense then. if it is supplemented by information about the external circumstances under which the events take place This information identifies the location, for example. the time and, if applicable, the reason for the Events and are not the »result» of a ZcitaMauf summarized. Who "- ·, these» circumstances can be foreseen or change only rarely, the signals that characterize them can be fixed in one Be stored in the recording device, it being sufficient to share them with the Output a message about the result of the events.

The object of the invention is therefore to provide a device to create the type specified at the beginning, which, in a robust design, suitable for rough workshop operation, can optionally be perforated of exchangeable message carriers with fixed code words and of counting words on the basis of commands from the machines in an economically and technically sensible way.

The device according to the invention is characterized by an adjustable code disk on which Message carrier with fixed coding aussvechsell-.ar are attached, on one side, and switched by two of the machine alternately and code disks actuated for punching while the other code disk is being indexed, on which consecutive numbers are coded, on the other side of the perforated tape.

According to the invention, a message is divided into two groups, with the first group consisting of information about current events and the second group from information about constant or themselves less often changing circumstances exist. This has the advantage that the coding mechanism is calibrated can adapt a limited number of all messages possible in a specific area. Thus becomes

By reducing the technical effort, there is also a message recording on punched tape possible where it previously had to be omitted for reasons of economy. This is the example the control of a production process in a manufacturing company.

In order to be able to draw conclusions at any time about the capacity of a company and the status of production and to be able to carry out the necessary costs onä wage calculations, reliable information must be available about the working hours and the working speed of personnel and machines and the number of manufactured parts. It is now common practice to collect the information at the end of each working day in handwritten reports on special forms that provide information about work performance and loss of work as a result of malfunctions. So-called time-quantity recorders, which are attached to the processing machines, are also used to automate this process. Such a scribe consists of a circular sheet, which rotates fully within a layer, and a pen arranged above the circular sheet, which writes a mostly radial line on the sheet after each workpiece has been completed. The message reproduced on the circular sheet, which contains information in the form of lines about the number of pieces produced and machine downtimes, is still made by manual entries, such as the operator's card number. Order number, date, processing type and reason for any downtime added.

The news on the circular sheet and the work reports mentioned are published at longer intervals, about weekly or monthly, together evaluated with the time stamped on the workforce card. Because this evaluation in most cases an electronic data processing system takes over the messages must be implemented beforehand on suitable information carriers, such as punched strips, which is complicated Equipment and trained operators are required. The long and costly journey from capturing the message can be saved until it is entered in a data processing system, when all the necessary information is automatically sent to the processing machine on a punched tape are issued.

Div.s can be realized in an economical way, if the order used for this purpose; to the Character of the message to be recorded can be adapted, as is the case with the device according to the invention the case is. For example, there are some messages for checking a machine tool (e.g. the inventory number of the machine), while other messages, such as plug-in cards from the operator, Date, order number, etc.) change at longer intervals. Another news so z. B. the number of processed pieces and the processing time per piece change constantly. For such cases, i.e. when some information is repeated frequently, the conventional ones are universal Strip punches, which are designed to receive any message, too expensive. The system would be uneconomical due to the resulting redundancy in the implementation. Besides that are the well-known punching devices for the rough workshop: ieb too sensitive and difficult in the Service. For these reasons, the automatic message recording is directly on the machine has not yet been carried out.

In the device according to the invention, for example, the messages about the identifier of the machine, the workpieces and the personnel as:> Circumstances of the work process on the code disk be stored with hard coding, while the

ίο other code disk the number of pieces manufactured Record workpieces as "counting result". In an advantageous embodiment, on both sides of the Perforated strip punch pins arranged, which are acted upon by the code disks. Through this it is

possible to punch different messages simultaneously on the punched tape so that both hole combinations lie close together on the strip.

In a further embodiment, two are alternating »Forwarded codes read on one

common axis rotatable. stored and coded on the circumference by pegs with consecutive numbers. This has the advantage that counting pulses arriving during a punching process are not lost.

In a preferred arrangement, the axes of the code disks run towards one another and towards the surface of the punched tape parallel and are perpendicular to the perforated edge. The punched tape runs with advantage vertically from top to bottom past the punching pins.

The interchangeability of the plate-shaped message carrier with fixed coding on the one code disk is beneficial in that, when the device is installed on a machine tool, a message carrier in a certain combination of holes or pins, e.g. B. information about the operator can contain, while another message carrier provides information about the order number and the name of the workpiece, etc. The message carriers, each with a fixed profile, can be pushed onto the code disk at the beginning of each shift. In this way, errors that can occur due to incorrect setting of movable pins are completely eliminated. The embodiment described is particularly advantageous for a manufacturing company because of its robustness and its low sensitivity to contamination. Holes instead of pins can also be provided in the counting code discs.
Further details and advantages of the invention are explained in more detail using an exemplary embodiment with reference to the drawing.
