Machine for the automatic production of material test samples.

The invention relates to a machine for automatic production of material test samples, with a marking device, a cutting device and a sorting device, in the manner of a transfer machine.

It is already known to use the following work steps to obtain samples for material testing:

A material test specimen is made from a matrix plate Scissors or Gasscheneiden obtained and marked with an identification number e.g. marked with the plate number »on the test item.

This test item is clearly entered in a sample book and cutting lines are also marked on the test item, as predetermined according to the book, Uffl the test item into individual test items cut to a predetermined size.

Thirdly, the Marking of cutting lines carried out.

Fourth, the rait marking lines and Test specimen provided with plate numbers cut into individual test specimens and

fifth are the individual test specimens cut out of the material divided into plates by a sorting device.

However, these steps are carried out by hand and considerable laboratory work is required for the large number of specimens required in series production to win.

The invention is based on the object of specifying a machine or a device system for series production required large number of test items completely to win automatically.

According to the invention it is proposed that a marking device, a lateral cutting device, a longitudinal slitting device and a sorting device arranged on a transport device at predetermined equal intervals are that a first adjusting device is present, through which each of these devices can be switched on and through which Transport device is adjusted in sections by a distance corresponding to these distances forward, that a second

Adjusting device is available through which one to be treated or metal plate serving as the test object, in particular steel plate, is fed to this transport device every time the transport device is adjusted by a distance is, and that a third adjusting device is available, which the work processes of this facility, facilities, Device or devices regulates, so that the test object serving steel plate, marked, cut to size in accordance with a predetermined die or pattern and is sorted.

According to the invention, groups of differently working devices or devices are arranged in one or more work paths or work lines, it being essential that after the test object or the material to be treated has been introduced into the transfer machine, this test object automatically passes through a row or line of treatment devices or devices is treated while the specimen is aur ^s of the transfer apparatus. Preferably, a transfer machine and a transfer system are used in which a number of work steps are carried out automatically, e.g. for the production of a desired sample piece as a relatively thick steel plate from a given raw steel test piece,

The machine according to the invention saves work and achieved the high effective efficiency and precision,

Circuit of the test specimen feed device (not shown) of the material preparation station 1 started. These output signals switch on a drive device (not shown) by means of which the direction switch stage 2 and the transport device 7 are switched on. As a result, a new test specimen 15 is fed to the material preparation station 1 of the switch stage 2 and arrives at the marking device 3 in the direction of the arrow, this arrow departing from the switch stage 2 in the drawing. Simultaneously with this, a test specimen 15 ', which was now marked by the marking device 3, is fed to the subsequent cutting device h , and then the test specimen is fed to the longitudinal slitting device 5 and the test specimen ^{treated by the slit burner 5 1} is then placed in the sorting device 6. FIGS. 3a, 3b and 3c show various examples of patterns for test specimens and FIG.

An encoder 8 is actuated by the output signal of the coincidence circuit 13 and converts the input information from the card & or tape-based unit i6. So a converted signal is obtained, which contains data that the new from the preparation. Station 1 relate to the test specimen, these data, for example, relate to the sample number, plate thickness, marking letters and the hardness of the material, and the converted signal is stored in the memory. 9 saved. If on the transport device 7 a new test item is fed to the marking device 3 with the help of the switch stage 2 from the station 1 after a new test item is fed to the switch stage by a material feed device (not shown) of the station 1, via the follower circuit 12 ', so At the same time, the information signal stored in the memory 9 is shifted to the parallel shift register 10 so that an output signal is sent to the decoder 11, and the signal stored in the register is shifted to the register 10 'so that an output signal is sent to the decoder 11' , and the signal contained in this register in the memory part is shifted to the register 10 "and gives an output to the decoder 11 ', and the signal stored in the last register is shifted to the register 10"' and gives an output to the decoder 11 '·' Correspondingly read 11 or sample the decoders 11 to 11 '* · the new signals, u nd, corresponding to this signal sample,.

works follower circuit 12 to the working machine or device 3 to 6 for the test items to be monitored, which have been supplied to these facilities in the aforementioned manner was.

Are the work sequences of the machine or device 3 to ended, an end-of-work signal is fed independently to the coincidence circuit 13 from the respective devices, and the work processes of all these facilities are finished, an output signal is given again to the coincidence circuit 13, which causes the duty cycle the signal transmission is repeated.

What the. Operation or workflow of the 2nd work line of the System is or are these the same as for the 1st working line of the system.

Further, when the 1st and 2nd work lines of the system operate together, there is a priority determination circuit 14 to improve the closed cycle time. This circuit Ik receives an output signal from the coincidence circuit 13 of the respective work line and uses the output signal as a drive input signal of the encoder ^ of the switch stage 2 and the transport device 7.

Therefore, if the output of the coincidence stage 13 of the 2nd work line is formed earlier as compared with that 1st work line output signal because the work flow switch level 2 is activated in the 2nd working line earlier than those in the 1st working line.

Drifted to the next test item on the 2 »work street align, and the output signal of the encoder 8 · · is in the memory 9 of the 2nd work line with the help of the train " subordinate AND gate 19 is saved. If the work of the 1st Work line ended earlier than the work on the 2nd work line, so it is easy to understand that the work flow then run the other way round. The type of working method after # <tf · new test item from the material preparation station. 1 has been fed to the work line, the same ivie indicated above, and accordingly speaking details can be omitted here.

It should also be noted that a manually operated switch is used or button can use to feed input signals in the encoder 8 only when a material to be tested or the like is fed to the work line for the purpose of a completed work flow or if the one with a card or a band equipped unit 1ö is out of order.

It is true that the above invention is described on the basis of an exemplary embodiment which works with 2 working lines and uses k devices in order to cut the test specimen in a mechanical manner and to collect the work result. However, it is understood by an average person skilled in the art that the teaching of the invention also extends "to equivalent embodiments, depending on the individual case, including a larger number of work lines and facilities *
