Abstract

1515607 Trimming moulded ceramic handles V E WISSENSCHAFTLICH-TECHNISCHER BETRIEB KERAMIK 6 Oct 1976 [9 Oct 1975] 41552/76 Heading B5A In apparatus for trimming and cutting freshly moulded ceramic handles prior to attaching them to vessels, pairs of handles each attached to a core 1 are located upon supports 3 and 4 carried by plates 38 themselves releasably supported upon a turntable 2. The handles are indexed to a station III at which a resiliently supported vibrating member is lowered into contact with the handles to cause a smoothing out of the irregularities in the handles by thixotropic flow. The handles are then indexed to a station V where the ends of the handles are cut to conform with the surface of the vessels to which they are to be attached. Cutting is effected by blades 27, 28 (see Fig. 4) carried by arms 21, 22 pivoted to levers 19 and 20. The levers are pivotable by cylinders 17, 18 to position where their free ends abut stops 23 and 24 respectively. Further movement of the levers causes the arms 21 and 22 to pivot relative to the levers, against the action of springs 31, 32, and the blades to effect the cutting operation. Retraction of cylinders 17 and 18 causes withdrawal of the blades &c. to their initial positions. The cut and trimmed handles are then indexed to a station VI at which they are transferred on to a take-off conveyor 51. Transfer is effected by a pair of electromagnets 44, 45 mounted upon the ends of arms 39 and a take-over plate 50 carried at the end of an arm 46. In operation, the plates 38 are bodily picked up by the electromagnets on arm 39 and pivoted to a position at which they are transferred on to the take-over plates. The arm 46 is pivoted to bring the take-over plates to a position above the take-off conveyor and the handles slip from the take-over plates on to the conveyor. Alternatively the take-off conveyor can be replaced by a second turntable. In a further alternative (see Fig. 6, not shown) the plates 50 are deposited on to the take-off conveyor and the arm electromagnetically picks up an empty plate for receiving the next handle.

Description

(54) INSTALLATION FOR TREATMENT OF CERAMIC

PRODUCTS

one

The invention relates to the processing of ceramic products and can be used in the processing of pens, cups and other products.

Closest to the proposed technical solution is an installation for processing ceramic products, including a rotary table, a receiving, unloading, clamping and stripping device 1J.

A disadvantage of the known installations is low productivity.

The purpose of the invention is to increase productivity.

The goal is achieved by the fact that the installation for processing ceramic products, including a rotary table, receiving, unloading, clamping and stripping devices, is equipped with rotary cutting devices driven by power cylinders, one of which is located above the table, and the other is under it, In this case, each device is made in the form of a lever with a curvilinear knife fixed with a hinge on it, the shape of which corresponds to the shape of the product, and the wiping devices are placed on the receiving device and nabzheny vibroexciters E, and the receiving device is mounted for vertical movement by actuators, wherein the turntable is provided with a cover plate with clamps products, and unloading device - the pivot arm for detachably products.

In installation, the fixture of products on the patch plate can be made in the form of an electromagnet.

In this case, the knives can be made replaceable.

FIG. 1 shows the proposed device; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. 2; in fig. 4 shows a section B-B in FIG. one; in fig. 5 shows a section of a CC in FIG. one; in fig. 6 is a sectional view of DD-D. one.

The installation contains a rotary table 1, receiving 2, unloading 3, clamping 4 fixtures and protective devices

5, which are placed on the receiving device 2 and are supplied with vibration exciters

6. The receiving device is installed on the lifting shtang 7, mounted on the power cylinder 8 mounted on the frame 9.

The cutting tools 10 and 11 are located one above the turntable 1 and the other below it.

Each cutting device is made in the form of a lever 12 with a curvilinear knife 13 hinged on it, the shape of which corresponds to the shape of the product. Each cutting device has a displacement drive from a power cylinder 14. Knives 13 separate knobs 15 from the core portion. On the surface of the table 1, an overlay plate 16 is fixed with fixtures of the product in the form of electromagnets 17, 18. The unloading device is equipped with pivoting levers 19 for removing the products.

The installation works as follows.

From the loading device, the untreated double handle 20 is fed to the pivot foot 1, after which it is centered by the clamping device 4, then the table is rotated and the double handle is fed to the wiper 5, the vibration exciter 6 is turned on and the butt weld is driven in with simultaneous cleaning of the internal seam. After the stripping is completed, the wiper is raised, after which the table is rotated. Then the power cylinders 14 move to a certain position, first the arms 12 with knives 13. This position is fixed by stops 21. Then the power cylinders 14 knives 13 separate the handles from the core part, after which the knives are removed from the table motion zone 1. After turning the table, the individual handles 15 are placed on the plates 16, where they are fixed by electromagnets 17 18, then the levers 19 of the handle are fed to the conveyor 22.
