(54) AUTOMATIC LINE TRANSPORT SYSTEM

one

The invention relates to transportation systems of automatic lines, integrating technological installations. The invention has been developed in relation to the process of painting products by the method of electrodeposition, but can be used in other areas of technology: in metallurgy, in metalworking, in the glass industry, in the baking industry, etc.

A known transport system of an automatic line, comprising a closed chain conveyor with hangers for products, passing through the process plant, and an associated transfer device made in the form of replaceable cartridges with lodgings in product row I.

However, some of the complexity of the product reloading process, due to the need for reverse movement of a closed chain conveyor with hangers for products when the latter is overloaded to a replaceable cassette, complicates the line control system.

The purpose of the invention is to simplify the process of handling products.

The goal is achieved by the fact that the reloading device cassette is located between the descending and ascending sections of the closed chain conveyor and perpendicular to them, made in the form of a closed chain conveyor with the product holders attached to its links and its periodic movement drive and equipped with fixed on it from the side of the mentioned downstream and upstream sections of the conveyor with brackets located perpendicular to the latter and at an angle of inclination to the conveyor belt about the device, respectively, to receive and issue products from it.

In addition, the reloading device cassette is equipped with support runners located along its working section.

15 conveyor belt and above the bearing surfaces of the lodgements of its chain links.

FIG. 1 is a schematic diagram of the transport system; in fig. 2 - version of its execution; in fig. 3 - overload device with a cassette installed;

20 in FIG. 4 is a view A of FIG. 3; in fig. 5 is a view B in FIG. 2; in fig. 6 is a sectional view BB in FIG. 2; in fig. 7 - location and operation of the clips; in fig. 8 - reloading products from the cassette to the conveyor. The transport system is designed to serve at least one technological installation 1 and is a main route 2, made in the form of a closed chain conveyor 3, an additional route 4 that intersects the main route 2 at the interface 5 and is equipped with interchangeable cassettes b for products 7 At the junction of tracks 2 and 4 there is a single transshipment (loading and unloading) device 8, equipped with loading and unloading of cassettes b on the device 8 and back, and products 7 from the cassette 6 to the conveyor 3 o the main track 2 and back - from the conveyor 3 to the cassette 6. The main track 2 is made in the form of a closed double-chain conveyor 3 (see Fig. 2) carrying the stops 9 (Fig. 8), located in place of the fingers of a chain with a step equal to step products. The stops 9 can be hung with painted products 7 using horizontal transverse rods 10, at the ends of which are kerchiefs 11 (Fig. 4), fixing the rods 10 on the stops 9 of both chains of the conveyor 3, connecting them to each other. The conveyor 3 (FIG. 2) has a downward 12 and an upward 13 portions, between which a transshipment device 8 is located. Each cassette 6 for products (FIG. 3) has a common frame 14 welded from angled steel, with which a pair of support runners are rigidly fastened 15 for the rods 10, with the trigger ends 16. The skids 15 are arranged horizontally, parallel to the base of the frame 14. Along the skids 15, the connecting chains 17 are located with the lodgments 18 in the form of protruding plugs 15 beyond the dimensions of the rails. The tie chain 17 is tensioned between the sprockets 19 and 20, the axis of rotation of which is rigidly fixed to the frame 14. The sprockets 19 have clamps 21 (see Fig. 8) fixing the chain 17 in the position defined by the angular position of the sprocket 19. Thus ( when latch 21 is released), the linking chain 17 is able to move parallel to the supporting runner m 15. On the horizontal part of the support runners 15, the lodgement 18 protrudes beyond the plane of the support runners 15, and at the trigger ends 16 passes below. The link of the linking chain 17 in all areas below the supporting runners 15 (see Fig. 4). A single transshipment device 8 is placed between the downward 12 and the upstream 13 sections of the double-chain conveyor 3 of the main route 2 and has a stepper pusher 22 with an independent drive in the form of a hydraulic cylinder 23. The overload device 8 has a loading table 24 and spring-loaded latches 25, which fix the base of the frame 14 of the cassette 6. For moving the cassettes 6 along the supplementary route 4, trolleys 26 are provided (Figs. 6 and 7), the rollers of the pallet 27 of which are at the level of the rollers of the station 8 platform. of inverse formed as abutments 9, 28 and the discharge boot 29 (FIG. 8) brackets lodgements 18. The apparatus operates as follows. Products 7, arriving at the painting, are loaded into the cassette 6, placing them on the support runners x 15 so that the rods 10, lying with their weight (the weight of the whole product) on the runners x 15, fall into the inner part of the cradle plug 18. With average dimensions products 7 (or when placing small-sized products in standard containers) for each fork of the cradle 18 there is one product 7 (rods 10). When large-sized products x 7 products placed through the plug. In the process of loading products into the cassette 6, the retainer 21 of the sprocket 19 fixes the binding chain 17 and the position of the cradle 18, and thus the products 7 on the support runners x 15 and generally in the cassette 6. In this position, the cassette 6 is mounted on the trolley 26, and it is ready to move along the additional route 4. Next, items 7 of the next cassette 6 are loaded, and the loaded cassette 6 either waits until the space in the device 8 is made free from the previous cassette 6 or is delivered on the trolley 26 to the device 8 . (In additional route 4 there are several rails O ways suitable to the device 8 on three sides, so the reserve can nahbdits row 26 loaded with cassette 6) prepared for painting trolleys. When approaching station 8, the cart 26 presses the spring-loaded latches 25 with its stops, loading the latter, and the loading table stops 24 inserts the cassette latches on the cart 26. Thus, the opposite stops are sunk, releasing the cassette 6 on the cart and allowing the passage of the cassette 6 to the boot table 24. At the same time, the guide rollers, along which the cassette 6 moves from the carriage 26 to the loading table 24 of the device 8 to the opposite spring-loaded clips 25, are connected along the same axis. The carriage 2 released from the cassette 6 is retracted. 6, the trolley's stop moves away from the spring-loaded latch 25, which fixes the cassette 6. The guide rollers prevent lateral movement of the cassette 6. The cassette 6 is strictly fixed on the loading table 24 of the device 8. The whole process of loading the cassettes on the device takes two minutes, which is less than one third the entire cycle of passing one

products 7 through technological equipment 1 coloring; The fixed position of the cassette 6 in the device 8 provides the interface of the means for transferring the products 7 from the cassette 6 to the conveyor 3 of the main route 2 located in the device 8 and on the cassette 6 closest (free) to the downstream 12 section of the conveyor 3 fork of the cradle 18 ( located on the cassette 6) is oriented towards the discharge bracket 28, the loading bracket 29 is located close under the trigger ends of the 16 supporting runners 15.

The first, which did not fit in the descending 12 section of the conveyor 3, painted and dried product 7, abutted against the discharge bracket 28 with the rod 10, as the conveyor 3 moves downward, removes the rod 10 with kerchiefs 11 onto the stops 9 of the conveyor 3 and transfers it to the discharge bracket 28. The stop 9 goes out from under the rod 10 and finally slides along the unloading bracket 28 into the fork of the cradle 18, oriented along the unloading bracket. An emphasis 9, which has gone out from under the rod 10, drives the step pusher 22 of the binding chain 17. The step pusher 22 of the linking chain 17 moves the bar of the rod 10 along the support runners 15 by one step. In this case, the rod 10 located in the cradle 18 carries along the connecting chain 17 and with it all placed on the support skids x 15 and located in the cradles 18, the rods 10 (and the products 7 suspended on them). Closest to the ascending 13 section of the rod 10, moving along the supporting runner m 15 for a total step length, goes to the trigger ends 16, and the lodgement 18 of the connecting chain 17, in which this rod was hooked, goes below the trigger ends, withdrawing the rod 10 from engaging and not preventing it from sliding on the trigger ends 16 onto the loading bracket 29. Having reached the loading bracket 29, the rod 10 is located exactly on the trajectory of the stops 9 at the upstream 13 section of the conveyor 3 and waits for the approach of the nearest upward stop 9 (from the unloading 28 to boot 29 brackets, stops 9 are free from shtang 10). The nearest ascending stop 9 picks up the rod 10 by the kerchief 11 and transports the product 7 suspended on it further along the main route 2 to the technological installations 1 (see Fig. 2). Having completed all the dyeing processing units 1, the product 7 approaches the drying process installation 1 and is transferred to a second conveyor passing through the drying processing installation 1, where the products are compacted. Pass the second conveyor of the main route 2, passing through the drying equipment 1, colored and dried (finished)

The product 7 again gets on the double-chain conveyor 3 and, on the descending section 12, approaches the discharge bracket 28, on which, with the described image of the template, the finished product 7 is automatically overloaded to the cassette 6.

As the new products pass through the technological units 1 for dyeing and drying along the main route 2, the cartridge 6 is automatically filled with ready-made products 7. After the last 16 are gone from the trigger ends in the cartridge 6 standing in the device 8, the unpainted product is given a signal and the cartridge 6 ready for reloading from device 8. For this on rail tracks

, additional track 4 (as indicated above, loading and unloading of cassettes can be carried out from all three sides of the device 8) roll the cart 26 without the cartridge 6, with the mutually opposite stops of the cart 26 and the platform of the loading table 24 retracting the spring-loaded latches 25, then the cartridge 6 with painted products is pushed onto the trolley 26. The cart 26 with the cartridge 6 filled with finished products 7 is retracted from the loading table 24 of the injector 8, thus returning the latches 25 to the raised position and transporting re additional route 4 to the finished goods warehouse. The station platform 8 is ready to receive a new cassette 6 with products 7 still to be painted. A new cassette 6 is loaded into the device 8. as proposed.

The use of the transport system in an automatic coating line provides the following technical advantages compared to existing systems: the rhythm of the additional track does not depend on the rhythm of the transfer station and the main route; the possibility of the automatic line failing due to the use of cassettes with pre-loaded products is excluded; facilitates the work of the operators serving the line by using an overload station; the number of staff can be reduced, since the cassettes are loaded with articles in advance and with a certain reserve at the machining section.
