摘要:
In order to achieve reproducible operating parameters of the shaping process of an I.S. glassware forming machine, a central control of all blowing and cooling air flows is proposed, in which in accordance with sections a volume flow of the cooling air including the inlet-side and outlet-side temperatures thereof are measured by means of a measuring device (51, 52) and a heat loss which is associated with the section is ascertained. The heat thus removed in sections is compared with standard values, wherein in the event that tolerance zones are exceeded a variation of the volume flow is initiated by the actuation of restrictors (53, 54). All of the sections of the glassware forming machine which are intended for passage of cooling air are monitored in this way, namely on the basis of a determinable heat loss, so that uniform cooling conditions, which are adapted to a mathematical model, and in this respect a reproducible product quality are achieved.

A dead plate arrangement for a glass forming machine is characterized by a housing (33) which is bordered on the upper side by a dead plate (1) which is divided into fields (16, 16′, 16″) intended for putting hollow glass articles to be cooled thereon, wherein to each field, a dynamic pressure chamber (3) is allocated which is connected to a supply air chamber (4) via a valve (9), and wherein the supply air chamber (4) is connected to a cooling air supply via a valve (5). The valves (5, 9) are continuously controllable between an opening position and a closed position so that the pressure can be set for each of the dynamic pressure chambers (3), and therefore the cooling capacity of each of the fields (16, 16′, 16″) can be set individually depending on the properties of the hollow glass article to be cooled. In connection with database-supported setpoint values for article-specific dimensioning of the cooling air flows of each field, an individual cooling capacity according to demand can be implemented which is adapted to the respective hollow glass article.

Each hollow glass object (7) is pushed by a push-off unit from a dead plate (1) along a curved path (10) onto the conveyor belt (5) in such a way that the curved path (10) is brought tangentially to a contact point (11) in a movement direction (6) of the conveyor belt (5). Subsequent to the contact point (11) each hollow glass object (7) is pushed further by the push-off unit by a further linear path portion (12) in the movement direction (6) of the conveyor belt (5) as far as a release point (13) in which the push-off unit is released from the hollow glass object (7). The push-off unit is then moved back to the starting point (8).

A repositionable hot-glass contact pad composed at least in part of a relatively high-strength nonmetallic material having one or more repositionable support projections and a glass-contact surface. The high strength nonmetallic material and use of multiple support projections allow reliable attachment of the pad to a metal support structure in a plurality of positions to handle a variety of hot-glass article shapes and sizes with minimal checking or other damage.

The pusher mechanism (14) associated with an I.S. glassware forming machine (10) are controlled by a controller (30) which provides control signals which cause the mechanisms (14) to operate. The controller senses the passage past a particular location of ware (1 to 6) of ware as it is transported by a conveyor (16) on to which the pusher mechanisms (14) transfer the ware. The controller determines the spacing (s1 to S5) on the conveyor (16) of ware from different sections (12) of the machine (10), compares the spacing with a predetermined, desired, spacing and, in the event that said spacing differs from said predetermined spacing by more than a predetermined tolerance, advances or retards the supply of control signals to at least one of the pusher mechanisms (14) which transfers the ware concerned.

An apparatus for carrying bottles, having a pusher for moving the bottles and a servomotor for reciprocally rotating the pusher within a predetermined angular displacement, comprising means for emitting start and stop signals of the servomotor, servo-control means for supplying a drive current to the servomotor so as to control the angular velocity of the servomotor, and for stopping the supply of the drive current to the servomotor when the servomotor is subject to an excess load above a predetermined value. The servomotor is an AC servomotor driven by the servo-control means.

A conveyor cam adjusting apparatus permitting adjustment of the radial position of each cam on a drive shaft while it is rotating. A plurality of individual electric motors are mounted for rotation about a common drive shaft each motor being associated with a single cam. Each motor is provided with a means for manually selectively connecting it to a control means in order to enable an operator to rotate the associated cam relative to the common drive shaft while the shaft is rotating. A sensing means may be used to detect the position of each cam relative to a predetermined reference position and the output of the sensing means may be used by a computer control means to automatically selectively activate each motor to adjust the associated cam accordingly.

This invention relates to conveyor systems and more particularly to article handling or positioning mechanisms for serially conveying or transporting hot glass containers between two or more work stations and into precise locations on alignment. The systems utilize heat-resistant fingers or arms to provide spaced-apart modules for retaining the glass articles, the fingers or arms being readily replaceable and reversible in ready-releasing locking arrangement.
摘要:
A conveyor used to move and if necessary cool objects from a multiple sections in-line production machine, such as a thermoforming machine. The design is sectional, each section comprising a cooling station with high-low control of the cooling media and a push-out device used to transfer the objects from the cooling plate onto the moving conveyor belt. The pusher consists of an arm swinging around a stud, the latter also moving on a circular path, the correct sequence being obtained from a control box timed by the corresponding production machine section. The sections are secured together in the number corresponding to the number of sections of the production machine thus providing a suitable conveyor for a machine with any number of sections.
