The invention relates to packaging technology, in particular to devices for molding (manufacturing) liners for fragile cylindrical glass products, for example, ampoules, and is an improvement of the device according to the main author. St. № 1 123943.

A device for forming an insert for ampoules is known, comprising a carrier with an insert carrier, a die and die stamp and a mechanism for feeding the insert into the carrier. In this case, the stamp is mounted coaxially with the feed mechanism and its die and punch are made in the form of plate packs. Between the die and the punch there is a presser bar with through windows in which the punch plates are installed with the possibility of reciprocating movement. Through molding channels are made at the end of the die, the punch is rigidly fixed to the punch holder, and the feed mechanism to the carriers is made in the form of a pusher connected to the carriage, while the punch holder, the punch, the clamping plate and the matrix are made coaxially through the pusher passage holes. The clamping plate is spring-loaded relative to the punch holder, and the pusher is spring-loaded relative to the carriage, with the carriage and the pressing plate mounted for reciprocating movement in the direction of movement of the punch.

The purpose of the invention is the safety of the device in operation by

introducing control over the presence of an insert in the zone of its formation, elimination of see and break, contribution to the process of their formation and placement in the carrier of the conveyor, as well as clogging of the forming channels of the matrix by breaking the lateral partitions of the insert in the process of dragging them through the matrix.

0 Ampoule forming unit for ampoules contains a billet input supply mechanism (not shown), a stamp with a movable punch I and a fixed die 2 for forming 5 inserts made of two parts (packages) 3 and 4 in the form of a set of plates 5 and 6 each, movable the clamping bar 7 with windows 8 for the passage of the plates 5 of the punch I, located between the die 2 and the punch I of the stamp, the mechanism 9 for inserting inserts into the carrier 10, mounted on an endless chain conveyor 11, the mechanism 9 is made in the form of a movable pusher 12 with a plate 13, mouth ment of the die along the axis of symmetry and mounted on the carriage 14 with the possibility of reciprocating movement of the latter along the guide columns 15 Yui them in gishsKOc-iHj perpendicular napravleggiyu .podachi preform liner for guiding .16 vkladsha, mounted before the matrix 2 GOVERNMENTAL stamp. In the middle part of the movable elements of the strain on the pressure plate 7, the punch holder 17 with the punch 1 and the die 2, respectively, openings (holes) 18-20 are made for the passage of the plate 13 of the pusher 12 of the feeding mechanism 9 to the carrier 10. Putin 5 of the punch I is placed in the windows 8 of the presser bar 7 with the possibility of reciprocating relative to the latter and rigidly fixed in the punch holder 17, and the plates 6 of the matrix 2 are displaced relative to the plates 5 of the punch I in the transverse direction. Molding channels 2I are made in the matrix. The punch holder I7 with the punch 1 and the pressing plate 7 of the stamp are mounted with the possibility of reciprocating movement along guide columns 22 under the action of the lever-rocker mechanism 23 interacting with its roller 24 with the corresponding cam (not shown). The carriage 14 with the pusher 12 of the mechanism 9 is mounted with the possibility reciprocating movement under the action of a lever mechanism 25, interacting with its roller 26 with a corresponding cam (not shown. The pressure bar 7 with windows 8 and I8 for respectively, the plates 5 of the punch 1 and the plate 13 of the pusher 12 are movably connected to the punch holder 17 by a spring 27., and the pusher 12 of the mechanism 9 with the carriage 14 is spring 28. On the upper part of the guide 16 for the billet blank above the die 2, a control mechanism is mounted the presence of a workpiece insert, which is made of a photosensor .29 and an illuminator 30. On the carriage 14, the centering pin 31 is periodically mounted, periodically interacting with the corresponding sockets (not shown) of the carrier 10 and spring-loaded springs 32 relative to the carriage 14 the pusher 12 of the mechanism 9 for supplying inserts to the carrier 10, while the end of one of the center pins 3 is provided with an abutment 33 periodically acting on the limit switch 34 rigidly mounted on the carriage 14 of the pusher 12. The matrix 2 is made removable and fixed to the device body 35 by means of racks 36 and lining 37, wherein each plate 6 of the packages 3 and 4 of the matrix 2 in its middle part is made in the form of a knife 38 with an open arc-shaped contour 39. The matrix 2, the guide columns 15 and 22, as well as lever-link mechanisms 23 and 25 secured to the building mustache 35 device. The device for forming the liner for ampoules works as follows. The liner blanks are fed alternately one by one between the die 2 and the die 1 with the clamping bar 7, by means of a mechanism for feeding them, the stability and regularity of feeding the liner workpiece is controlled by a photosensor 29, which, in case of an insert workpiece stuck in the liner 16, turns off the drive device, thereby eliminating the clogging of the matrix 2 of the device fragments of inserts. After that, under the action of the lever-rocker mechanism 23 from the corresponding cam (not shown the Punch holder I7 with the punch 1 and the presser bar 7 is moved along the guide columns 22 to the die 2, while the presser plate 7 with its front surface presses the insert to the plates 6 of the die 2 places that are not subject to bending, and stops. With further movement of the punch holder I7 towards the die 2 of the plate .5 of the punch J, overcoming the resistance of the springs 27, are displaced along the windows 8 of the clamping bar 7 and and 6 of the matrix 2, fold the side parts (partitions) of the insert, forming a longitudinal edge on it. After forming the lateral longitudinal partitions on the insert, the Punch holder 17 with the punch I and the supporting bar 7 returns to its original position, releasing the insert 7 from the lever-link mechanism 23. pressing it against the plates 6 of the matrix 2. After that, under the action of the cuneo-lever mechanism 25, which interacts with its roller 26 with the corresponding cam (not shown), the recess 14 of the mechanism 9 moves the iO guide columns 15 to the side;

matrix 2, initially with its centering pins 31, interacting with the corresponding THesflaNm (not shown) carriers 10, shift the gray ones, ensuring strict co-jness of their output window and the molding channels 21 of the matrix 2, regardless of the conveyor chain hood 11, then the plate 13 of the pusher 12, the passage through the windows (openings) of 18-20 th, respectively, the punch-knob 17. With the punch 1, the presser bar 7 and the die 2, bends the insert in the middle part in the transverse direction, folds it in half and pulling t5 bent side parts {burnout DKI) of the insert molding channels 21 through matrix 2 transmits to the support 10, fastened to an endless conveyor tsepiom. 20

I

At the moment of folding the insert twice and dragging even the incomplete bent side partitions of the insert through the molding channels 21 of the matrix 2, knife elements 38 first interact with them, and then open circular copier 39 of each of the plates 6 of package 3 and 4 of the matrix 2, with a smooth finish. torshi limb of the lateral longitudinal partitions of the insert. In the case of a large displacement of the carrier 10 relative to the exit window and the molding channels 21 of the matrix 2, the centering 35 pins 31, resting against the end of the carrier 10 and overcoming the resistance of the springs 32, are displaced towards the carriage

14 and one of them focus 33

affects the limit switch 34, rigidly fixed on the carriage 14, the pusher 12, which turns off the drive of the device, excluding the contact and breakage of the drive when it is placed in the carrier 10 of the conveyor 11,

After completion of the process of laying (feeding) the formed insert into the carriers 10, the carriage 14 with the pusher 12 of the mechanism 9 is returned to its original position by the action of the rocker-lever mechanism 25 and the operation cycle of the device is repeated.

The expected annual economic effect from the use of the proposed device will be 3.2 thousand rubles.
