(54) ROTARY CONVEYOR SORTING MACHINE

PRODUCTS

The invention relates to a control and sorting technique, namely, rotor conveyor machines for sorting products whose dimensions are controlled by mechanical means. Such machines consist of a rotor with measuring stations placed on its periphery and product carriers, or a rounded conveyor with product carriers.

Known rotary conveyor machines 1, in measuring stations of which control means are combined with sorting means; Moreover, each control means is also made in the form of a reciprocating movable measuring rod, and the sorting tool combined with it is in the form of a lever mechanism. The measuring brush has a measuring base movable along it, due to which the difference in the positions of the measuring bases does not affect the control results. Thus, similar rotor-conveyor machines, having high productivity, provide sufficient accuracy of control and sorting. However, they can sort items by the same limit, namely: select only those items that have a controlled size less than the allowable quality as defective.

The purpose of the invention is to expand technological capabilities by being able to sort items not only by lower, but also by upper tolerance limit.

This goal is achieved by the fact that in a well-known rotor-conveyor machine containing a rotor with carriers of sorted products and evenly placed measuring stations on its periphery, each of which has a measuring probe installed with the possibility of reciprocating movement, coaxially measuring brush, a sorting mechanism and chag for controlling the position of the measuring rod, mounted on the measuring probe, the sorting mechanism is made in the form of a spring-loaded clip mounted on the measuring rod With a spring-loaded lever grip mounted on it, 20 vol.

FIG. 1 shows a rotary conveyor machine, a plan view; in fig. 2 - machine conveyor, longitudinal section; in fig. 3 - the same plan view; in fig. 4 is the same, section A-A in FIG. one; in fig. 5 - measuring station, while monitoring a suitable case; in fig. 6 - the same, when checking the body without a gasket; in fig. 7 - the same, when checking the body with two gaskets. A rotary conveyor machine for sorting the valve body cases of aerosol packages is a combination of power supply rotors 1, control and sorting 2 and delivery of suitable products 3, rounded by a chain conveyor 4 equipped with carriers 5 of sortable cases 6. Each carrier 5 consists of a sleeve 7 and an upper plate 8 of the outer link of the chain conveyor 4; with this. each layer | , and 8 serves as the measuring base of the sorted cases 6.. The control and sorting rotor 2 is a rotating base 9 mounted in bearings 10 and 11 on column 12. Along the periphery of the rotating base 9, measuring stations 13 are located. Each station 13 is mounted 1; 1 is mounted in a pusher 14, a cam mechanism, the spatial cam 15 of which fixed in the upper part of the column 12. In each pusher 14 is placed reciprocating moving with him measuring rod 16 with level 17. Each measuring rod 16 is equipped with a movable along the probe 18 measuring base, otorrhea equipped with means controlling the position of the measuring rod 16; this means is made in the form of a two-arm lever 19, one arm 20 of which interacts with the stage 17 of the measuring rod 16. Each measuring station 13 also has a means for sorting, which is made in the form of a yoke 21 in contact with the second shoulder 22 of the lever 19. The holder 21 is equipped with a lever gripping 23 defective housings 6. Lever grips 23 are controlled by cams 24 attached to the upper part of the rotatable base 9. For passage of lever grips 23 under the defective housings 6, two plates are provided in each plate 8 of conveyor 4 Section 25: To the bottom of the rotatable base 9, there is attached a gear wheel 26, and above it to the flange 27, an asterisk 28, bent around a chain conveyor 4. Collection 29 serves to receive rejected cases 6. Around the periphery of the rotor there are 3 suitable products - size: control Capable grabs. The GO collection serves to receive fit cases 6. Fit cases 6 have one gasket 31, rejected or do not have gaskets, or have two gaskets. The rotor conveyor for control and sorting works as follows. Sorted housing 6 comes from the hopper of the rotor 1 in the carrier 5 of the conveyor L, which transports them to the rotor 2 control and sorting. Under the action of the cam 15, the pushers 14 with the measuring stations 13 are gradually lowered onto the sorted bodies 6. At the same time, the probe 18 of each measuring station 13 abuts against the corresponding plate 8 of the conveyor 4, which is the measuring base. Then, upon further lowering of the pusher 14, the measuring pin 16 rests on the sorted lever 19 and, depending on the quality of the sorted body 6 (with one gasket, without gasket or with two gaskets), takes one of three positions. which are shown respectively in FIG. 5, 6 and 7. Meanwhile, the pusher 14 continues to fall, and with it the holder 21 together with the lever grip 23. In the first case, if the housing 6 is fit, i.e., has a gasket 31, then the shoulder 22 of the lever 19 becomes the path of the yoke 21 and stops it, together with the yoke. My 21 stops the lever grip 23 in the position when its lower shoulder rests on the lateral surface of the probe 18. If the body 6 is defective, i.e. it does not have a gasket 31 or has two gaskets 31 the arm of the lever 19 takes up such a position that allows the cage 21 to continue to fall, since The lower grip arm 23 passes the side surface of the probe 18, enters the corresponding groove 25 of the plate 8 under the defective body 6. Then the pushers 14 with the measuring stations 13 begin to rise, while the usable bodies 6 remain in the carrier 5 and are transported by the conveyor 4 to the rotor 3. The rejected bodies 6 when lifting the pushers 14 are removed by the grippers 23 from the carriers 5 of the conveyor 4 and held until they interact with the cams 24. This occurs in the area of the rotor where the measuring stations 13 are above sat. This is where the grippers release defective housings 6, which fall into the collector 29. Fitted housings 6 on the arc of curvature by the conveyor 4 of the rotor 3 are taken out of the grips from the carriers 5 and then released into the collection of 30 fit products. Thus, the invention allows with high accuracy and performance, sort products by completeness or linear size by two limits of the tolerance field.
