Description

one

The invention relates to automatic coating and can be used in paint systems for applying coatings by pneumatic or pneumoelectrostatic spraying methods during painting of products consisting of flat or reduced to them surfaces moving on a conveyor in such a way that their side surfaces are mainly parallel to the direction of movement. conveyor belt

A device for coloring is known, which contains spray guns and the mechanism of their reciprocating movement in guides.

The disadvantage of this device is that it is impossible to change the vertical stroke, it will spray ole.

It is also known a coating device comprising a pantograph system of levers with a spray gun connected to a carriage mounted in guides with the possibility of reciprocating motion.

The disadvantages of this device is the limited range of sizes of the machined

products height, low production at low sizes of products and the structural complexity of the control unit supply air for spraying.

The purpose of the invention is to increase the height range of the painted products.

To achieve this, the device is equipped with a swinging mechanism of a leverage system, made in the form of a hinged link with the link arms, interacting with the carrier mounted on the drive rail to the carriage mounted on the above-mentioned scraps. Such a device divides the entire stroke of the dispensers by their movement together with the carriage with the help of a cooler-chain mechanism of the carriage drive and by the movement of the dispensers relative to the carriage using the pantograph system of levers with an autonomous drive, which allows coloring different BbiCoie products without readjusting the individual mechanisms of the device with a full working cycle sprayers, i.e. both up and down. Fig, 1 shows a device, a longitudinal section; in fig. 2 is a section A-A in FIG. 1; in fig. 3 - section B-B in Fig. 1, the coating device D with a stand 1, support-guide structure 2 with cylindrical directions fixed on it, 5 points 3 and a fence 4, Carriage 5 installed in guides 3 with the possibility of sliding on rollers 6 on the outside of the guides 3, On the carriage 5, the rocker 7 is fixed with a groove interacting with a water 8 rigidly connected with a vertical chain 9 driven by the variator motor 10. Inside the carriage 5 there is a shaped rail 11 with rollers 12, wrapping around When the cylindrical guide 3 and to the carrier 13 through the associated connecting link 14 with the pantographic lever system comprising levers connected by hinges 15 and 16 and the link 17, which is fixed to the bracket 18 with the sprayer adjustably its position. At a certain ratio of the lengths of the levers, the nozzles move strictly vertically within certain limits of their angular displacements. Since the carriage 5 has a sufficiently large weight, the device is equipped with a balancing system comprising a chain 19, an EO chi 2O and a load 21. Individual reciprocating - translational movement of the shaped rail - the carriage 11, which is transformed into a swinging motion of a pantograph system of levers 15, 16, 17, includes the variable speed motor 22, the chain drive 23 and the pinwheel 24, the swing of the levers of the pantograph system is carried out when the carrier 13 is acting on the link 14, the supporting - guiding structure 2 has a movement device relative to one hundred Plains 1 for approximating or removing a device for intrinsically coloring a product (not shown in the drawing). The operation of the device can be carried out in the following modes: in the operation mode only of the drive of the pantograph lever system; in the drive only mode of operation, the return of the carriage movement is continued; in the mode of joint operation of the carriage drives and the system of levers. Work in the first mode. When the motor-variator 22 is turned on through the chain drive 23 and the pinwheel 24, the shafts of which engage with the shaped cuts of the rail - carriage 11, the latter reciprocates relative to the carriage 5 along the guides 3, through the carrier 13 and the slide 14 is returnable the movement of the carriage 11 is transformed into the swinging movement of the pantograph system of levers 15, 16, 17, with a resolution of 18. When working in this mode, paint products having small dimensions in height. When the dimensions of the products increase in height, they are transferred to the second direction of work, i.e., the variator motor 10 is switched on and through the chain gear 9, the carrier 8 and the slide 7 are transmitted to the carriage 5, which is combined with the pantograph system of levers 15, 16, 17 and the nozzles 18 reciprocates by the height of the cylindrical guides 3. If the dimensions of the product being painted are higher in height than the cylindrical guides 3, the device operates in the third mode, i.e. with the motors turned on - variators 10 and 22, the nozzles 18 make a complex movement: reciprocating together with the carriage 5 and the swinging movement of the pantograph CHCTGFVIM levers 15, 16, 17,. The described device, in its small dimensions, is universal in coloring products of various sizes in height. DETAILED DESCRIPTION OF THE INVENTION A coating apparatus comprising a pantograph leverage system with a spray gun, connected to a carriage mounted in guides with the possibility of reciprocating motion, of which - and so on. that, in order to increase the height of the range of products to be painted, the device is equipped with a swinging mechanism of a system of levers made in the form of a hinge connected to the levers of the knapsack interacting with the carrier mounted on the drive rail - the carriage mounted on the mentioned lines: 1.
