(54) DEVICE FOR REMOVING CAPS FROM THE NECK OF THE TARE

(57) The invention can be used in medicine for opening empty bottles capped with aluminum caps with rubber stoppers. The essence of the invention lies in the fact that the cap puller includes symmetrically arranged plate knives, the cutting edges of each of which are inclined to the plane of the table, for gradually cutting the side forming cap, the plate knives are mounted on brackets forming movable carriages with the possibility of adjusting the angle between the directions their movement. 8 ill.

The invention relates to equipment used in medicine, in particular to devices for removing, from the neck of a used container, aluminum caps with rubber stoppers.

Cap closure devices are known in which cap removal is carried out using a pliers method.

A disadvantage of these designs is that. that manual labor is required that requires a lot of effort to break the caps, and these devices are not suitable for removing caps from vessels with a threaded neck.

A cap removal device is also known, selected as a prototype, comprising a matrix mounted on the base, a lever-handle with profiled cams pivotally connected to the base, a carriage with a grip with a tooth at its end, and three spring-loaded pushers mounted on the base.

The disadvantages of the known design are its low productivity, additional manual screwing of the caps after their expansion, and the complexity of manufacturing individual parts of the device are required. The possibility of reusing the removed caps is also doubtful, since when the contents are consumed, the protective seal breaks from the cap.

The aim of the invention is to increase labor productivity, expand technological capabilities and improve safety conditions.

This is achieved by that. that the cap-removing device comprises guides mounted on a tabletop with movable carriages in which plate knives are placed for cutting metal caps rolled on the vessel.

The carriage is connected by a lever to a manual control handle and via a link to a foot control pedal.

From FIG. 1 shows a device; in FIG. - section aa in FIG. 1; in FIG. 3 is a top view of FIG. 1; in FIG. 4 - design features of vessels a and in FIG. 5 - green II in FIG. 1, not fig. 6 - node I in FIG. 3; and FIG. 7-node III in FIG. 1; in FIG. 8-section BB in FIG. 6 occurrences in the neck of the neck of vessels a and b.

The device consists of a table 1, with a supporting plate 2 and spacers 3 and 4. On the plate 2 are fixed rails 5 with movable carriages 6 and 7 for processing vessels of type a (Fig. 5) and vessels of type b (Fig. 7), a comb 8 is also installed on the table to remove, if necessary, the cut-off caps and stops of the socket 9 for vessels a and 10 for vessels b. The movement of the carriages 6, 7 is carried out by the lever 11 from the manual control knob 12 or from the foot pedal 13 through the link 14, on which the return spring 15 and the stop 16 are mounted. and 7 differ from each other only in the number of plate knives: 17, 18 for processing vessels a and 19, 20 for vessels b. The guides consist of brackets 21, which are fixed on the tabletop 2 with bolts 22 and 23. On the bracket 21, for guiding the retails 6, 7, screws 24 fasten a parallel 25 along which the carriage body slides. To eliminate the vertical weight load (kink), the casing is supported on a plane ynqjp / 26, which is attached to the tabletop with 2 screws 27. The set of knives 17, 18 and 19, 20 consists of plates made of cutting steel with a thickness of not more than 2 mm . In each plate, a return spring 28 is fixed. The sharpening of the knife sets 17.18 and 19, 20 in the carriages is mirror symmetric. Knives are fixed in the carriage bodies on x 29 axes. Cases with knives

closed by lids 30 and 31 (Fig. 5) and lids 32 and 33 (Fig. 7). If necessary, knife sharpening covers 30, 31 and 32, 33 are given, knife packages 17, 18 and 19, 20 are removed from the axes 29. Each removed packet is fixed with technological bolts that are inserted: one into the hole of the axis 29, the other into the technological hole 34 (Fig. b). Sharpening angles are shown in FIG. 6 and 8. The grinding angle in FIG. 8 provides a gradual entry of the cutting knives into the surface of the cut-off cap, which reduces the applied force on the lever 11.

The use of plate knives allows you to remove (cut) rolled caps from both the threaded and cylindrical shapes of the neck of the vessels.

The movement of the carriages along the guide 25 is carried out by a rocker 35, which is fixed in the end sleeve 36 of the lever 11 with a screw 37. In the bracket 38 of each carriage, ball stops 39 are installed, which allow for adjustment and the need to install and fix the carriages at the required angle in the center of the cut-off cap. The drive lever 11 with its central part is mounted in

5 to the table bracket with a finger 40. T ha 14 of the foot drive to the lever 11 is fastened with a fork 41 with a finger 42. The return spring 15 allows the carriages 6 and 7 to return to their original position. An effort

0 of the spring 15 is adjusted by a stop 16 and is fixed by a nut 43.

Comb 8 is used if the cut-off cap does not come off the neck of the vessel and thereby eliminates possible hand injuries.

Sockets 9 and 10 are installed so that the neck of the processed soybean / da with a cap freely, with a gap of not more than 1 mm, fits into the socket for its stop.

0 The machine operates as follows.

The empty used Shchsud is inserted upside down into the corresponding stop socket, and with a manual drive or foot pedal through the drive lever

5 are driven with a knives with knives, which, when resting in the cap of its gap, are south. The cap after its cut from the yrlyushka falls. If for some reason the cut-off cap does not come off the neck, then a comb is used.

The time for the removal operation is rolled up. A cap of any type is spent within 3-4 s.

Feasibility

5 consists in the fact that the use of a device for cutting rolled-up metal caps on vessels eliminates manual labor to remove the caps, increases productivity, while excluding

0 injury to staff.
