Description

GERMAN

The invention relates to a device for the joint adjustment of tool carriers in Paper bag machines. Devices for independent use are known in paper processing machines Adjustment of tool units and has already proposed two circular knives working together to adjust together. Right-hand and left-hand threaded spindles are also used as movement devices known from tool carriers.

The invention relates to a device for the common adjustment of tool carriers, in pairs are arranged symmetrically to the center line of the machining area of the workpiece and tools wear above and below the material web. With this tool arrangement were previously To adjust four tool carriers individually in each tool group, which is very time-consuming, especially in most cases a very precise setting is necessary.

The invention provides a device for the common symmetrical adjustment of four tool carriers or tools specified, which is characterized according to the invention by one in one Side frame of the machine frame not axially displaceable, but rotatably mounted spindle with a right-hand and a left-hand thread section, through a yoke each with right-hand and left-hand thread Nut thread on the corresponding spindle thread and one each through the machine frame connecting pipe between the two arms of the yoke that connects to the machine frame first lies and the also lying tool carriers, as well as through one each, in the connecting pipes slidably guided rod between the two arms of the other yoke and the other Tool carriers.

The invention is illustrated below by way of example rotating tool, namely a creasing device for pre-creasing the page covers of transversely conveyed Cross-bottom valve bags described in soil-making machines and on the basis of drawings explained.

The drawings show:

Fig. 1 is an elevation of the device in the end position according to Fig. 2,

FIG. 2 is a plan view of the device corresponding to FIG. ₁

Fig. 3 is a plan view of the device in the other end position.

On one side of the line of symmetry 1 of the machining area One pair of the interacting creasing tools 2, 3 is located on the workpieces and on the other side of the line of symmetry 1, the other pair of cooperating creasing tools 4, 5. The creasing tools, of which the top, 2 and 4,

so designed as a male mold and the lower ones, 3 and 5, as a female mold are, have a circular cross-section and run with an upper drive shaft 6 and one lower drive shaft 7, on which they are arranged to be longitudinally displaceable. Between the tool pairs a conveyor disk 8 or 9 is attached in the symmetry line 1 on the same shafts 6 or 7, which cannot be moved in the axial direction.

The creasing tools 2 to 5 are each with a disk on their side facing away from the line of symmetry connected, in which there is a circumferential groove 9, 10, 11, 12. A roller each engages in these grooves, 13,14, 15, 16, one which, preferably rotatable about ball bearings, is mounted at the end of a tool carrier 17, 18, 19, 20 is.

The tool carriers 17 and 18 of one pair of grooving tools 2, 3 are each on the end of a tube 21 and 22 and the tool carriers 19 and 20 of the other pair of grooving tools 4, 5 on each end of a star ' 23 and 24 clamped.

The tubes 21 and 22 are in the side frame 2 £ r of the machine frame and slidably mounted on her other, threaded end in the arms of a yoke 26 with two ring nuts 27 each attached.

The rods 23 and 24 pass through the tubes 21 and 22 guided through it and at its other end, which is provided with a threaded pin, with two nuts 28 fastened in the arms of a second yoke 29. In the middle part of the yokes 26 and 29 there is one each Sleeve with collar, 30 and 31, used rotatably, one of which, for example the sleeve 30, inside with Right-hand thread and the other, for example the sleeve 31, is internally provided with a left-hand thread. on the side of the yoke opposite the collar is a knurled ring 32 provided with a shoulder

attached to the sleeves so that they are fixed in the axial direction in the yokes, but are rotatable. At they are normally prevented from rotating by a knurled pressure screw 33 each. The purpose of this Arrangement is explained below.

With the right-hand and left-hand thread of the bushings 30 and 31, the yokes 26 and 29 sit on the corresponding, right-hand and left-hand threaded parts of a spindle 34 which are mounted in the side frame 25 of the machine frame with a cylindrical, thread-free part 35 rotatably mounted and by two Adjusting rings 36 on the part 35 is secured against axial movement. The spindle carries at its front end a pinned handwheel 37.

If you turn the handwheel 37 and thus the spindle 34, the yokes 26 and 29 migrate as a result of the Rechtsbzw. Left-hand thread in opposite directions. The tubes 21 and 22 and the rods 23 and 24 move with them and take the pair of tools 2, 3 in one direction and the pair of tools 4, 5 in the other direction. Since the legal and the left-hand thread have the same pitch, this movement takes place by the same amount after both Sides of the line of symmetry. For the threads specified for example, a clockwise rotation has an enlargement the distance between the tool pairs result. The yokes are the widest apart when the tool pairs are closest together and vice versa.

So first of all the symmetry of the tool pairs 2, 3 and 4, 5 exactly to the symmetry line 1 can be adjusted, the above-described arrangement is the detachable, provided with the internal thread Bushings 30 and 31 are provided in the yokes 26 and 29. Do you want one or the other pair of tools? adjust for yourself, you loosen the corresponding knurled pressure screw 33 and can then by turning the corresponding knurled ring 32, the bushing 30 or 31 in question in its Twist yoke 26 or 29, whereby only this one yoke and thus only the relevant one pair of tools is shifted sideways. This can be brought to the same distance from the line of symmetry 1, like the other pair of tools. This setting only needs to be done once during assembly the device to take place. For this purpose, the arrangement of only one sleeve in one of the both yokes. The internal thread can then be attached directly in the other yoke.

Above the tools, one of the symmetry line attached to both sides or only to one side progressing scale, not shown after which you can easily adjust the tools to the respective format can make. The invention fully achieves the intended purpose of the invention; it enables four tools working together in pairs to the right and left of a symmetry line in a paper sack machine to be adjusted together, which saves a lot of time when adjusting these machines on different formats is achieved.

The adjusting device according to the invention can also be used with other machining tools be, for example with longitudinal cutting tools or the like. You can also with appropriate simplification the yokes for adjustment for one-sided only above or only below the workpiece path Tools are applied. You can also with a corresponding design of the yokes a single Use adjustment device for several tool groups.
