Embodiment is shown. In the drawing shows

Fig. 1 the bag testing device according to the invention in plan view,

Fig. La the adjusting device for the machine halves in a deeper horizontal section of the device according to FIG. 1,

F i g. 2 shows a side view of FIG. 1,

F i g. 3 di ^ photocells according to fig. 1 and 2 schematically in plan view in connection with a sack to be tested.

1 and 2 denote the side walls of the bag machine in which the bag inspection device according to the invention is installed. For this purpose, three cross members 3, 4, 5 (Fig. 1 and 2) are attached to each side wall, each of which carries a plate 6 at their free ends. Between the side walls 1 and 2 and the plates 6, two U-shaped holders 7, 8 are slidably mounted on the cross members 4 and j and held by a threaded spindle 9, which is rotatably mounted in the machine side frames but secured against longitudinal displacement. The spindles 9 are designed as right-hand and left-hand threaded spindles, so that the distance between the holders 7 and 8 can be changed by turning a handwheel 10 attached to the free end of the spindle 9 protruding from the side frame. Each of the four holders carries two photocells, namely the holder 7, the photocells 11, 12 and the holder 8, the photocells 13, 14. The photocells are height-adjustable by means of screws on the upright arms of the holder, which are provided with elongated holes 15. The photocells 12 and 14 are each used to scan the bottom width of the respective bag bottom to be checked, while the photocells 11 and 13 are intended to control the leading inclined grooves of the floors. If the width of the bag bottoms is changed, all eight photocells can be adjusted very easily to the new width by turning the handwheels 10, using a scale 16 that is calibrated according to the bottom widths and is attached to the Haller 8 and one to the Holder 7 attached pointer 17 cooperates. The basic setting of the line of symmetry of the control device of each bag bottom to the center of the bag bottom can be set at a screw 18, which is _{rotatably mounted in the machine side frame I 1} 2 and secured against longitudinal displacement and with a thread in an eye 19 each of a bearing 20 axially displaceable in the side frames for the threaded spindle 9 engages.

When changing the bag length, i. H. the distance between the two bag bottoms is the machine side frame 2 together with the bag testing device attached to it for a bag bottom as Whole postponed. For this purpose, threaded spindles 21 (FIG. 1 a) are provided over the length of the bag machine distributed there. The threaded spindles 21 are secured against longitudinal displacement but can be rotated in flange bearings 22 and engage with internally threaded flanges 23. The bearing 22 shown and the flange 23 are each attached to an end wall 24 ', 25' of two cross members 24 and 25, which with their other end wall 24 "and 25" are attached to the machine side frames 1 and 2. The machine side frame 1 is together with a further plate 6 'screwed to the cross member 24 on the machine foundation frame slidable screwed to the machine foundation frame in a manner not shown, while the machine side frame 2 is screwed together with one to the traverse 25 further plate 6 "is slidably mounted on the machine foundation frame, so that when the Spindles 21 the machine side frame 2 with all parts fastened in it opposite the machine side frame 1 and the parts attached to it is moved. The drive is provided by the spindles 21 each via a bevel gear set 26, 27 from a common drive shaft 28, which in a suitable manner is drivable.

'5 Since the scanning of the sloping edges of the floors in contrast to the scanning of the floor width, which during of the entire passage of the floors has to take place at a very specific point in time with regard to the location this beveled edge is bound when the sack passes through, is used to display this point in time According to the main patent, another photocell 29 is used from the front edge of the bag their passage is affected. Since this is the distance between the front edge of the bag and the sloping edges scanning photocells 11, 13 arrives and this distance changes when the Bodenbreitc changes also changes, the other photocell 29 scanning the front edge of the sack is by means of in the longitudinal direction of the machine a threaded spindle 30 adjustable on a handwheel 31. The spindle 30 is in a nut thread provided holder 32 and carries at its free end another rotatably mounted on it Holder 33. The holder 33 is held by a rod 34 which is fastened to it and which is guided in the first holder 32 and has a scale 35 calibrated according to floor widths, opposite an edge of the holder 32 as Pointer acts so that the photocell 29 by means of the handwheel 31 and the scale 3ä in the simplest way the floor width produced in each case is adjustable. The holder 32 is on a rod 36 by means of a spring 37 secured against rotation but stored adjustable along the rod, so that when changes are made to the Bag length an adjustment of the photocell 29 on the bag center level is possible. The photocell 29 is open the holder 33 can be clamped in a manner not shown further at the appropriate height in each case. In the same Thus, the photocells 11 to 14 are on the holders 7 and 8 in the manner shown for the photocells 11 and 13 bolts 38 screwed in the desired position clampable.

If the floor width is changed, all photocells are half the amount of change to the respective one To adjust the handwheel. While the scale interacting with a pointer moving in opposite directions 16 is to be laid out on a scale of 1: 1 for the width of the floor, the scale 35 is on a scale of 1: 2 for the width of the floor to interpret.

The reflective surfaces for the light beams of the reflective photo buttons 11 to 14 and 29 to be arranged below the sacked workpieces transported through the machine in the direction of arrow A or for the inlet under the inner bottom halves are dimensioned so large, in a manner not shown, that they are sufficient for the adjustment range of the photo cells.
