Description

The invention relates to devices for the supply of products and can be used in the chemical, pharmaceutical, food and other fields of industry, for example, in the packaging lines for liquids.

The purpose of the invention is to simplify the design of the device and increase productivity.

Figure 1 shows the device, a general view; figure 2 is a view of And figure 1; on fig.Z - view B in figure 1; figure 4 - section bb In figure 1.

A device for orienting and feeding items such as vials contains a belt conveyor 1, on an endless belt 2 of which, grips 3 for vials 4 are located with a certain pitch (less than the height of the vial) Two straight limiting strips moving in the transverse direction are located on the sides of the upper conveyor belt the ability to install them in a horizontal position at different heights (standard size) of the bottles. Between the restrictive bars closer to the center of the tape are located with the possibility of installing them in width and height (on the size of the bottle) two curved guide bars b curved to the axis of the belt mounted above the belt 2 of conveyor 1 with a gap for the neck of the bottle and forming in the middle part of the conveyor 1 a tapered section for the passage of the thickened portion of the vial between the guides. A gap a is formed between the guides and the neck of the vial (Fig. 4). Thus, if the neck of the bottle passes under one guideline 6, its bottom abuts against another.

At the output end of the conveyor, at the tip of the vial from the grip, a mechanism for orienting the bottles to a vertical position is installed on both sides, in the form of two vertical adjustable stops 7, which hold the bottle by the neck at the time of the fall. Moreover, the gap b (Fig. 2) between the abutment and the curved guide 6 is somewhat larger than the diameter of the neck, which eliminates the jamming of the bottle when it falls. Each stop is placed between the guide 6 and the stop bar 5.

At the end, a safety device 8 in the form of a funnel is installed under the transggort, helping with its conical upper walls to orient the falling bottle in an upright position. The safety device has a window 9 at the bottom for the removal of the vials by the discharge conveyor 10. Plank 11,

mounted between the curved guides 6 slightly above the diameter of the vials, discards incorrectly trapped vials, for example, one hundred located on the grips (Fig. 2, position III). A locking device, such as a photo sensor 12, turns off the conveyor drive 1 when the catcher overflows with vials. At the beginning of the conveyor is

0 a hopper 13 in which the lower end of the conveyor 1 is placed.

The device works as follows.

From the hopper 13 bottles 4 transport

5 by the tape 2 with the grips 3 are raised along the conveyor 1. Meeting on their way at the bend point, the guides 6 from the bottom, the bottles are shifted along the grips to the side, for example, to the right (Figure 2, position I).

0 The neck of the bottle passes under the opposite guide 6 and touches the restrictive bar 5. The bottle then moves upwardly without shifting to the side, since it is limited from the bottom side by the straight guide 6, and from the neck side by the restrictive bar five.

At the top of the conveyor at the point of capsizing the vial from the grip (on curvilinear

0 plot) stop 7 holds the bottle by the neck. As a result of the overturning moment caused by the inertia force of the moving bottle and the center of gravity shifted towards the bottom, the latter is displaced bottom to the safety device 8. The cone-shaped walls of the upper part of the catcher help the bottle to be oriented in the vertical position when it falls. The lower part of the catcher is made more narrow, preventing the vial from falling.

From the catcher through the window 9, the bottles are taken away by the discharge conveyor 10. When the catcher overflows, the locking device is activated, for example, the photosensor 12, a signal is given to disconnect the conveyor 1 and the bottles are stopped. Incorrectly oriented vials, for example, located on the grippers one hundred (figure 2, position III)

0 and not falling down themselves, are dropped by the bar 11 back to the bunkeo.

Similarly, the operation of the device when the position of the bottle in the capture of the neck to the left (position 2, figure 2). In this case

5 right, the guide 6 is bent; it displaces the vial beyond the bottom to the left as it is lifted by the conveyor belt. The vial with the neck passes under the left curved guide 6. When the vial is tilted, the left abutment 7 acts on the neck (delays).

The application of the invention allows to simplify the design, increase the reliability of the device, allows you to quickly make changeovers for various sizes of bottles with the help of restrictive plates and curved guides. This increases the equipment operation time and, consequently, its capacity by 5-10%.
