Marking-out device

专利摘要:
This invention relates to devices for moving thermoplastic hollow billets having a ring shape through a heating station to a blow molding machine. The purpose of the invention is to expand the technological capabilities of the device by transporting blanks of various diameters and ensuring uniform heating of the blanks due to rotation during heating. To do this, in a device that includes a vehicle in the form of an endless conveyor, carriers of workpieces mounted on the vehicle, the conveyor is made in the form of two toothed belts moving in the opposite direction, mounted parallel to each other in a vertical plane. The blank carriers are made in the form of two rings to support the blank, one of which is mounted on one toothed belt, and the other on the other toothed belt. The device is provided with a means of rotating the rings for supporting the workpiece, consisting of two endless belts, and mounted with the ability to interact with them drive rollers connected to the rings for supporting the workpiece. In addition, the device is equipped with at least one mechanism for changing the gap between the working branches of the toothed belts, made in the form of a screw drive mounted on the supporting frame horizontally across the direction of the working branches of the toothed belts. 4 hp f-ly, 4 ill.

专利说明:

The invention relates to a device for the production of blowing hollow articles from thermoplastics, and more particularly to a device for moving hollow articles having the form of a ring, through a heating station to a blow molding machine.
The purpose of the invention is the expansion of technological capabilities through
transporting workpieces of various diameters and ensuring uniform heating of the workpieces due to their rotation during heating.
FIG. 1 given schematically the device, the communities view; in fig. 7. - device for transporting blanks, top view; in fig. 3 shows section A-A in FIG. 2; in fig. 4 - the same, another

example of the arrangement of the holders of the blanks.
The device comprises a vehicle made in the form of a two-toothed belts 1 and 2 moving in the opposite direction, mounted in the support frame 3 in parallel in a vertical plane with the formation of a gap 4 between their workers — J in the gap 4 for placing the blanks. The belts 1 and 2 are mounted on the driven rollers 5 and 6 and the driving rollers 7 and 8, the roller 8 being connected with a V-belt 9 with stepless molding, and both rollers 7 and 8 being connected with one other belt 11 on both sides and the envelope are two small bypass rollers 12, which are parallel to each other 2 on one side of roller 7, due to which rotation of the arms 7 and 8 in opposite directions and movement of the toothed belts 1 and 2 in the opposite direction are ensured. 2 The device is provided with blank carriers made in the form of two rings 13 for supporting the blank, one of which is mounted on the belt 1 and the other on the belt 2, and means for rotating the rings 13 made in the form of two driving rollers 14 having annular grooves 15 on the side surface to which the rings 13 are attached, and two endless driving belts 16 placed in the grooves 15 of the rollers 14.
Rings 13 with means of rotation are mounted on belts x 1 and 2 by means of clamps 17 attached to them with bolts and pads 18 installed in the center of each of them, on one side of which two guide rollers 19 are mounted on axes with annular projections on the side surface and 20 in the form of a rail, spaced between them, with the ability to interact with the protrusions of the rollers 19, and on the other side of the lining on the axis 21 of one of the rollers 19 is attached a driving roller 14. The drive belts 16 are tensioned onto the bypass rollers 22 and move from Drives 23 and 24, made with stepless and synchronous control. To regulate the size of the gap between the working branches of the belts 1 and 2 when moving the blanks of different diameters, the device is equipped with at least one mechanism for changing the gap, made

in the form of a screw drive that includes a two-part screw 25 with left and right threads at opposite ends, guides 26 mounted on its ends, connected to straps 1 and 2, and flywheels 2 mounted on frame 3, for rotating the screw, fixed at the ends of the screw 25.
FIG. Figure 4 shows an example of the arrangement of the drive rollers 14 relative to the support rollers 19 when the guide rail 20 is fixed at the bottom of the support frame 3 and cooperates with the support rollers through round rods 28. In FIG. 1 is a diagram of an installation in which the proposed device for moving workpieces is used, including a heating station 29 installed on a horizontal section of a vehicle of a device; heat emitters 30 of which are fixed to a support frame 3 of a device, a sorting device 31 for blanks conveyed by the conveyor 32 with a device 33 for castings, and a blow molding machine 34 installed at the exit end of the vehicle. Movable blanks and reference numeral 35.
The device works as follows.
From the device 31 for the manufacture of castings, the conveyor 30, the blanks 33 enter the sorting device 29, and then are captured by rings 13 attached to the vehicle belts 1 and 2 of the device. When the belts 1 and 2 are moved, due to their movement in opposite directions and rotation of the supporting rings 13, the blanks 33 are rotated around their axis, as a result of which they are uniformly heated by the radiators. 28 when passing through the heating station 27. The speeds of movement of the belts 1 and 2 and the rings 13 are controlled by the drives 10, 23 and 24, so that the temperature equalization of the workpieces can be affected. In the case of movement of the workpieces 33 of different diameters, the width of the gap between the working branches of the belts 1 and 2 is changed, by turning the screw 25, thereby moving along the guides 26 connected with the belts 1 and 2, or together
they move from one another, or when the rotation changes, one to another, whereby the gap width can be adjusted infinitely.
