Description

The image refers to the means of automating the loading operations of technological equipment, and in particular to devices for oriented piece work of lengthy, thin and flexible objects, in particular, made of polymeric materials, for example, blanks of writing rods.

The purpose of the invention is to increase the performance of the device when supplying parts of long flexible rods by aligning them during freezing and eliminating the deflection. FIG. 1 shows a schematic of the boot device, a general view; in fig. 2 shows section A-A in FIG. 1. The loading device consists of a straightening mechanism, made in the form of a shaft 1 rotating in supports 2, a disk 3 fitted peripherally with slots 4, designed for accommodating parts 5. On both sides of the disk 3 there are inclined trunnions 6 centered on the shaft 1 , but not rotating, on which two lateral disks 7 fit freely, equipped with the same number of sockets as the disk 3. The outer diameter of the disks 7 is chosen so that they do not extend beyond the cylinder described by on the outside the diameter of the disk 3.

t-- For transmitting rotation from disk 3

The discs 7 are provided with a wheel 8, which is provided with rods 9, play the role of the hubs, and which engage with the discs 3 and 7 freely on the trunnion 6 and the wheel 8 rotates freely on its axis, and the movement is transmitted by at each moment in the corresponding grooves of all three disks.

The shaft 1 is connected by means of gears 10 and 11 to the shaft 12 of the drum 13. The latter, on the periphery, has slots 14 arranged with the same pitch as the slots 4 of the disk 3.

The gear ratio is chosen so that at the moment of the arrival of the next slot of the disk 3 in the place of the closest approach and the greatest removal of j disks 7 to this slot is opposed to the next slot of the drum 13.

Near the place of the closest approach of the discs 7 there is a tray 15 or a hopper containing a stock of parts 5. Parts 5 that fall into the slots of the discs 5

radially limited by inner 16 and outer 17 cylindrical guides, and end walls hold them from displacement in the direction of their axes

(not shown). In a specific example, the embodiments of the guides 16 are integral with the pins 6.

The device works as follows.

5 The shaft 1 rotates with the drum 13, the feed parts 5 fall into the slots of the discs 3 and 7 in the area of the tray 15. The discs rotate in the direction of arrow B and transport the parts

0 .5 between the inner 16 and outer 17 guides. At the same time, the distance between the discs gradually increases. Otherwise, discs 7, at first exciting parts for a small

5, the length (which greatly facilitates their dropping into the grooves.), As if moving apart, the transition to their ends. Due to this, the supplied part, the arrival at the place of approaching the drum 13, turns out to be forcibly rectified so that without any difficulties using the cutter 18 is pushed out of the grooves of the disks 3 and 7 into the slots of the drum 13, having a length equal to the length of the part .

five

In the zone close to the place of the greatest discrepancy of the discs 7, the axial length of the inner 16 directions is significantly reduced. In order to prevent undesirable deflection of the parts to the axis of the shaft 1, they are held by the surfaces of the nests of the disk 3, which are spaced from the axis of rotation of the shafts 1 at a distance equal to the radius of the guides.

As regards the discs 7, the position with respect to the bottom of each slot of these disks during rotation all the time changes: as one moves away from the place of closest approach or divergence of the disks 7, the supplied workpiece sinks deeper into the slot, and vice versa. Therefore, the sockets in the disks 7 have a depth greater than the sockets of the disk 3.

It should be noted that due to the inclined position of the disks 7 relative to the axis of the shaft 1, the diameter of each disk 7 is larger than disk 3.
