Definitions

  • the invention relates to an industrial sewing machine with an electronic control device, which triggers and controls one of various functions depending on the seam length produced, wherein a seam length section is defined by the product of stitch length and number of stitches, for which purpose the control device processes predetermined stitch lengths and stitch numbers for function control .
  • Controlling the functions of the sewing machine depending on the length of the seam produced in each case presupposes that the respectively completed one at all times Seam length is known. Then the necessary functions can be triggered, e.g. cutting, inserting a label, changing the differentials for folding or stretching the fabric.
  • EP-A-0 148 281 a non-volatile read / write memory that can be connected to the control device via plug connections is provided as a special feature, in which the program steps for a certain ready-made article are stored in a memory part while it is being produced different clothing sizes the associated different numbers of stitches are stored in a different memory area, in groups. A number of memories is provided in each group for a certain number of stitches, the number of stitches within each group differing in accordance with the respective clothing size.
  • the invention has for its object to provide an industrial sewing machine with an electronic control of the type mentioned, in which the specification of seam length sections necessary for function control and their correction can be carried out considerably less work.
  • this object is achieved in that the Input device for entering stitch lengths and setpoint and correction values is provided, and that the set length information is divided by the stitch length using a computing unit in the control device.
  • a single stitch length in connection with several lengths can be entered via the input device.
  • the length information is expediently entered in mm.
  • the arithmetic unit then divides the individual length specifications by the stitch length (several stitch lengths can also be entered), which results in the number of stitches for each seam length section. This number of stitches is then compared in operation in a manner known per se to the changing count of a number of stitches in order to trigger the desired function if they match.
  • the number of stitches can be calculated in the electronic control with the help of the computing unit for each individual sewing process.
  • the stored target length specification is then multiplied accordingly by a correction factor.
  • the number of stitches is first determined and saved in a preparation run after entering stitch lengths and target length specifications for each seam length section.
  • the correction value specified in mm is converted into a corresponding factor and the individual number of stitches is multiplied by this factor.
  • the electronic control has a microprocessor and a programmable read-only memory as a computing unit.
  • the present invention is particularly suitable for an industrial sewing machine which is equipped with an insertable storage part, as described in the above-mentioned EP-A-0 148 281. Accordingly, the invention provides in a further development: a memory section for the program steps of a clothing item to be sewn without the different seam length sections (for example in the form of stitch numbers) with different clothing sizes and a number of memory groups corresponding to the maximum number of executable program steps, each one of the number contains the number of memories corresponding to the different clothing sizes for the seam length sections of the individual clothing sizes belonging to the program step, with the memory of each storage group assigned to a specific clothing size being selected when the clothing size is entered using a keyboard of the input device.
  • a memory section for the program steps of a clothing item to be sewn without the different seam length sections (for example in the form of stitch numbers) with different clothing sizes and a number of memory groups corresponding to the maximum number of executable program steps each one of the number contains the number of memories corresponding to the different clothing sizes for the seam length sections of
  • FIG. 1 schematically shows an industrial sewing machine with a sewing head 1 on a table 2.
  • a sewing head 1 To control the sewing head 1, its drive and the additional device (not shown here), such as thread cutter, label feeder, stacker and the like, an electronic control device is provided in a housing 15. which is connected to the sewing head 1 via control lines 17 and is carried by a holder 16 on the table 2.
  • Fig. 2 shows the housing 15 of the electronic control device in a perspective view. Only the front plate 18 of the housing 15 is of interest here. On the front plate 18 there is a display device 7, which, for example, is 32 Characters comprehensive LCD display is executed. There is also a keyboard 19 on the front panel, via which the commands for programming and control can be entered. In addition, there is an access opening 20 for a storage cassette 13 on the front panel 18. Finally, a numeric keyboard 21 is provided on the left on the front panel 18.
  • the cassette 13 In its side facing the housing 15, the cassette 13 has a plurality of plug pins which can be inserted into corresponding sockets in the housing 15.
  • the control device contains: a microprocessor 3, an EPROM 4, a read / write memory 5 (RAM), a non-volatile read / write memory 6, which is contained in the cassette 13 (FIG. 2), the display device 7 , a control device designated overall with 8 for the sewing head and the additional devices, a control bus 9, a data bus 10 and an address bus 11.
  • the keyboard parts 19 and 21 are connected to the buses 9, 10, 11 in the manner shown in FIG. 3.
  • the non-volatile read / write memory hereinafter referred to as NOV-RAM 6, contains a memory section in which the program steps for a specific ready-made article are stored without the different number of stitches or target seam lengths provided for different ready-made sizes.
  • NOV-RAM 6 contains several groups of memories and counters, one of which is assigned to each memory. Each storage group is assigned to one of the program steps. Each memory in a group contains the different number of stitches or target seam lengths of the different clothing sizes of the article in question.
  • the cassette 13 in whose NOV-RAM 6 the associated sewing program is stored is inserted into the cassette holder 20.
  • the selection of the memories in which the number of stitches or desired seam lengths for the clothing size to be sewn by this article is stored is selected by entering the clothing size using the keyboard 19. This means that only the number of stitches or target seam lengths belonging to this clothing size are queried from the memories during the program run. With the help of the counters, the corresponding number of stitches is counted in order to trigger a certain function if the pre-stored number of stitches matches.
  • the new clothing size need only be entered using the keyboard 19 or 21 before the start of the first program step.
  • the NOV-RAM 6 can be programmed using the keyboards 19 and 21 when the cassette 13 is inserted into the receiving opening. But you can also use a special programming device, not shown here, for this purpose. With regard to the details of this external programming, reference is made to EP-A-0 148 281 already mentioned above.
  • the seam length sections required for function control and function triggering are not entered by entering the stitch number, but a stitch length is entered in conjunction with the nominal length information for the individual seam length sections. It is also possible to enter different stitch lengths for different sections.
  • This entry of stitch lengths and target length information for the individual seam length sections takes place via the keyboard 21, which is a numeric keyboard.
  • the entered numerical values are temporarily stored in the RAM 5, and the microprocessor 3 uses this information to calculate the number of stitches required for the control of each seam length section by dividing the individual nominal length information by the associated stitch length.
  • the resulting number of stitches is stored in the NOV-RAM 6 for a respective seam length section. After all values have been saved, you can start sewing. The number of stitches can also be calculated continuously during the sewing operation (on-line).
  • the number of stitches usually has to be corrected because the actual values for the length measurements have changed due to changes in the mechanics or for other reasons.
  • a correction is carried out using the keyboards 19 and 21 in such a way that a correction length in mm is additionally specified with the correction commands.
  • the microprocessor 3 calculates a correction factor from this correction value, and all the stitch numbers for the individual seam length sections are multiplied (or divided) with this correction factor.
  • the number of stitches for the individual sections was calculated and stored after the entry of stitch lengths and target length specifications for the individual seam length sections in order to be able to be called up directly.
  • the stored nominal length information is then corrected additively or multiplicatively with the entered correction value.
  • the subsequent process when calculating the individual Stitch numbers are the same as described above.
