    Preparatory to closing a filled upright sack by a zig-zag closure, grippers engage the flattened mouth end of the sack. A support is swung to a position adjacent the flattened end and swing arms cause the end to be folded onto the support. After rollers have been swung onto backing rollers to clamp the folded-over end, the grippers are opened and withdrawn by the swing arms.

    (54) DEVICE FOR BENDING THE MOUTH BAG
    权利要求:
    Claims (7)
    [1]
    The invention relates to equipment for packing bulk materials, and more specifically to a device for bending the neck of a bag, And can be used in various sectors of the national economy. A device for bending the neck of a bag is known, which contains a horizontal stand and grips the neck of the bag. However, the known device does not provide high performance. The purpose of the invention is to increase the productivity of the device. This is achieved by the fact that the proposed device for bending the top of the bag half is provided with a base plate for the latter mounted rotatably in a vertical plane and located in a working position corresponding to the plane folding the bag neck at an acute angle to the stand. The grip consists of grabs mounted on both sides of the plate with the possibility of rotation about the axis, parallel to the axis of rotation of the plate. At the same time, the plate is fixed on the ends of the levers, while the other ends are reinforced on the horizontal shaft. In addition, the levers are pivotally connected (J-shaped levers have pinch rollers at the ends, and grooves are formed in the plate in which the support rollers are mounted. The pinch rollers are fixed on the rod that connects the free ends of the i-shaped levers. Rollers spring-loaded and grabs attached to the shafts on which driven sprockets of chain gears are fitted with levers driven by power cylinders .Also, the plate with stand forms an angle of 25. The device for bending the neck is schematically shown in Fig. 1 An eshka in the direction of transportation, a general view; Fig. 2 is a view A of Fig.; Fig. 3 is a bag with a vertically positioned neck and on the left grapple grapple, top view; 5 is a view B in Fig. 4. The device comprises a horizontal stand (not shown), gripping the edge of the bag 1 and the base plate 2 for the neck of the bag mounted rotatably in a vertical plane. The base plate 2 is located in a working position corresponding to the plane of folding of the neck of the bag at an acute angle to the stand, with ohm plate 2 forms an angle with the stand 25. The grip consists of grabs 3 having rods 4 and mounted on both sides of the plate 2 rotatably about an axis parallel to the axis of rotation of the plate. The grabs 3 are mounted on shafts 5 and 6, on which are also cylindrical gears 7 and 8, intermesh with each other. A lever 9 is connected to the shaft b, the free end of which is connected to the piston by means of a rod of the power cylinder block 10. The shafts 5 and 6 are located in the housing 11, which is rigidly connected to the shaft 12. At the end of the shaft 12 there is a plate 13 with which the housing is connected of the power cylinder unit 10, in this case it triggers: neither the last grabs 3 can be rotated 90 ° in position 14. The shaft 12 is rotatably placed in the bearing housing 15 fixed on the free end of the chain transmission 16. The chain gear 16 is also connected to bed frame 17 and in the edge 18 bed frame in Lamy 19, which are mounted on parallel shafts 20. The arms 19 arranged in the frame 17 a shaft 21 on which the fixed arm 22 and levers 23. Levers 23 Nirni balloon connected to both levers 20 via the connecting rod 24. With the lever 22 is connected to the hinge. The piston rod 25 of the power cylinder block 26, by means of which the chain transmission 16 can be rotated to position 27. On shafts 12 and 19, the driven sprockets 28 and 29 are attached to the transmission chain 16. By means of a chain transmission 16, grabs 3 can to be rotated from a position in which the vertically disposed loading end 30 is gripped to position 31 when the loading end is placed on plate 2. Before this, the pressure and support rollers 32 and 33 should be rotated onto a fitted inverted container (not cauldron) Then at position 14 of the grabs 3 swivel sleeves can move back, where the next bag is waiting for them, which is gripped by the shank. When the bag is grabbed by the gravers 3, their rods 4 are pulled upwards from the boot end 30. The carrier plates 2 and the levers 34 are connected to the plates 35, in which a rotating shaft 36 is placed, with the lever 37 being connected to the latter. the free end of the lever 37 is pivotally connected to a block of power cylinders 38, with the cylinder head pivotally placed on the lever 39 rigidly connected to the shaft 40. The pivotally and-shaped are connected to the levers 34. the levers 41, the free ends of which are connected by a bar 42, and the pressure rollers 32 are fixed on the latter. In the plate 2 formed notches 43, in which the support rollers 33 are installed (figure 1 - solid lines). As a result of the actuation of the power cylinder unit 38, the rollers 32 can be deflected from the plate 2 to the position 44. The rollers 32 are rotatable freely placed on the levers 45, which in turn are fixed to be rotatable on the axis 46. The rollers are spring-loaded by means of springs (not shown ). The plate 2 is rigidly connected to the forming edge of the rod 47, while the plate 2 is reinforced by rectangular sections 48 which are rigidly connected to the plate 49. The plate 49 is connected to the plate 50, which can be adjusted relative to the plate 49 by means of longitudinal grooves 51. The levers 34 are rigidly fixed on the plate 50 and rigidly connected to the shaft 40, on which the lever 52 is pinched, pivotally connected to the rod of the power cylinder 53 for rotation. rod 47 to position 54, in which the walls 55 of the bags are at the level 56 of the material contained in the bag. The device works as follows. The vertically positioned end 30 of the large bag 1 is grasped by the grabs 3. The rods 47 with the supporting plate 2 are rotated to the position 54, after which the rods 4 are pulled upwards. The chain transfer 16 is rotated to position 27, with the result that the loading end 30 folds onto the support plate 2. Then the rollers 32 turn on the rollers 33 so that the loading end 30 is locked between the rollers. Next, the grabs 3 are opened and are rotated to the starting position by means of the pivoting arms. After the bag 1 is dispatched vertically to the plane (Fig. 1), the rod 47 moves in the opposite direction to its original position and the rollers 32 are lifted from the rollers 33. Next, the cycle of filling the bag is repeated. Claims I 1. A device for bending the neck of the bag, comprising a horizontal stand and a catch, the neck of the bag, characterized in that, in order to increase productivity, it is provided with a support plate for the neck of the bag, mounted to rotate the vertical plane and positioned S. in the working position corresponding to the plane of folding of the bag neck, at an acute angle to the stand, and the grip consists of grabs mounted on both sides of the slab with the possibility of rotation about an axis parallel to the axis of rotation of the slab.
