SU1520023A1 - Automatic machine for loading indicator tubes - Google Patents

Abstract

The invention relates to the construction and building materials industry, to glass production, to the field of manufacturing indicator tubes, and can be used in the chemical and pharmaceutical fields. The purpose of the invention is the expansion of technological capabilities, ensuring the provision of groups of blanks of different heights. To do this, in an automatic machine, each mechanism for lifting and pressing a group of blanks is made in the form of a carriage kinematically connected with a camshaft with damping elements and interacting with the rods of levers with stops. The carriage and levers are mounted on a common axis with the possibility of rotation. Each of the group of blanks 2 that hit the working position is pressed in the middle part of the strap 29 against the upper 30 and lower centering prisms. Under the action of the copier, the carriage 12 rotates on the axis 13, turning the levers 15. The levers 15 raise the rods 22 with the billet 2 tubes located on the tables 25, pressing their upper ends to the base surface 31 of the gear. 3 il.

technological capabilities, ensuring the provision of groups of blanks of different heights. For this, in the automaton — each mechanism for lifting and pressing the group of zagrotechs is made in the form of a carriage kinematically connected with the camshaft with damping elements and interacting with the stock levers with limiters. Carriage and levers. mounted on a common axis with the possibility of rotation. Each of the group of workpieces 2 that hit the working position is shown in the middle part of the strap 29 towards the upper 30 and lower centering prisms. Under the action of the copier, the carriage 12 rotates on the axis 13, turning the levers 15, the levers 15 raise the stem 22 with the billet 2 tubes located on the tables 25, pressing their upper ends to the base surface 31 of the gear mechanism, 3 or more.

The invention relates to the construction of the construction and building materials, glass production, the manufacture of indicator tubes and can be used in the chemical and pharmaceutical fields,

The aim of the invention is the expansion of technological capabilities, providing equipment for groups of workpieces of different heights.

Fig, 1 shows the machine, a general view; Fig, 2 - mechanism for lifting and pressing, cross section; Fig. 3 is a view A of Fig. 2 (with raised blanks).

The indicator tube loading machine contains a hopper 1 for blanks 2 tubes, a mechanism for feeding blanks 3, a grab mechanism 4 for moving workpieces, a mechanism for inserting a workpiece part, a mechanism for feeding a filler (indicator mass), a grid for inserting parts of a mesh 8. , the mechanism 9 for unloading the tubes, as well as the mechanisms 10 for lifting and pressing the group of blanks at the working positions. All elements of the machine are fixed on the frame 11, the machine has a drive with a cam shaft 20 and a control system (not shown). Each mechanism 10 lifting and pressing the group of blanks includes a carriage 12 mounted to rotate on an axis 13, the ends of which are rigidly fixed in the bracket 14. On the axis 13 also

two shoulders levers 15 are installed, equipped with limiters 16 of rotation, Damping elements 18 are placed under the shoulder 17 of the lever 15, Carriage 12 is connected to the hinge lever

connection 19 with a corresponding cam cam shaft 20

Above the shoulder 17 of each lever 15, there is a lower end 21 of a vertical stem 22 installed in guide sleeves 23 placed in a housing 24 fixed to station 11, and a supporting table 25 with a lower centering prism is fixed at the upper end of the stem 22 . A plug 26 is fastened on the rod 22 between the guide sleeves 23, against which the return spring 27 abuts, Vipka 26 and the screw 28 fixed in the housing 2A are designed to prevent the rod 22 from turning and setting the level of the table 25 in height.

The machine works as follows.

The blanks 2 are stacked horizontally in the hopper 1, from where they are removed by the mechanism 3 at the same time several pieces (in the example shown, three pieces) and transferred to the vertical position. The line of the clamshell mechanism 4 captures a group of blanks 2 and transports them along the machine sequentially to the position of equipment and control. The mechanism 5 inserts the fairings inside the blanks 2, the mechanism 6 drops the dose of the filler in them, after which the mechanism 7 inserts the nets. Mechanism 8 determines the presence of grids in the blanks 2 and discards blanks that turn out to be without grids. Mechanism 9 removes the loaded tubes from the machine.

The mechanisms 10 for lifting and pressing the blanks to the base surfaces by the mechanism of work work as follows. Each of the groups of blanks 2 that hit the working position Po is pressed in the middle part of the strip 29 against the upper 30 and lower centering prisms,

Under the action of the corresponding cam cam shaft 20 and the hinged link 19, the carriage 12 rotates on the axis 13, turning the levers 15 through the damping elements 18, which, overcoming the action of the springs 27, lift the rods 22 with 2 tubes on the tables 25 pressing their upper thoriums against the base surface 31 of the mechanism.

Upon completion of the process operation, the carriage 12 rotates in the opposite direction. The rods 22 with the tables 25 under the action of the springs 27 are lowered, occupying the initial position, the Grab mechanism 4 transfers the group of blanks to the next position. The cycle is repeated.
