Description

This invention relates to devices for turning hollow articles and can be used in light industry for turning gloves.

The purpose of the invention is to increase the durability.

FIG. Figure 1 shows an installation for inverting glove articles, a general view; in fig. 2 is a chamber for placing inverted articles, an axial section; in fig. 3 shows section A-A in FIG. 2

The installation comprises a vacuum pump 1 with a main pipe 2, a receiver 3 equipped with a valve 4, and a system of chambers 5 for accommodating inverted articles connected by a collector 6 to a receiver 3 The installation is equipped with an additional pipe 7 with a valve 8 connected to the main piping through a bypass line 9 and a manifold 10 for injecting air into the chambers 5 connected to the piping 7. The collectors 6 and 10 are connected to each of the chambers 5 by three-way valves 11. The main piping 2 has a safety valve Apan 12. The housing of each chamber 5 is made in the form of a hollow cylinder, but the free end of which has a removable conical tip 13 with a figured hole 14 and a hollow mandrel 15 in the shape of a hand, the ends of the fingers have holes 16. The thumb 17 of the mandrel is offset. In the cavity of the cylinder. The grid 18 is placed and is mounted for movement

piston 19. The latter is rigidly connected to the mandrel 15. A spring 20 is installed between the piston 19 and the grill 18. The mandrel 15 is installed in the nozzle 13 with a clearance.

The installation works as follows.

The vacuum pump 1 is turned on, which creates a vacuum in the receiver 3 and the collector 6 before the safety valve 4 trips. The air from the vacuum pump 1 through the oil-separator 21 enters the main pipe 2 with the safety valve 12, which is set to ejection pressure, and the closed valve 8 on the additional pipeline 7 enters the collector 10. When there is an excess of pressure, the safety valve 12 is activated and the air is partially released into the atmosphere. At the same time, the worker puts a glove on the mandrel 15 so that the fingers of the glove enter the fingers of the mandrel 15 and the wrist of the glove on the conical tip 13 Turn the three-way valve 11 into the Vacuum position. A vacuum is created in the cylinder. The pins of the mandrel are sealed through their holes 16 by the glove material, and the piston 19 together with the mandrel 15 and the glove begin to move in the cylinder 5 and the tip 13. The glove wrinkles, and since in the tip 13 there is a gap in the shaped hole 14, it starts to turn out . Upon further movement of the piston, the fingers of the glove are also turned out. When the piston 19 moves a stroke more than two lengths of the glove, the mandrel is detached from the fingers. The three-way valve 11 is turned to the Air position and under the action of it and the spring 20 the piston with the mandrel returns to its original position, pushing the glove onto the working table.

The valve 8 is made regulating. If the holding performance is not sufficient, the glove wrist cone 22 is clamped with a conic protrusion 22, for example, with a hoop.

Installation in other embodiments can be performed without fingers on the mandrel or in the absence of a piston 19 with a mandrel, for example, for rubber gloves. The acceptance of the variant depends on the flexibility and density of the materials of the glove products.
