Definitions
- the following invention is presented whose purpose is to introduce a series of modifications in the mechanism of the drying ovens for lids, so that it is possible to adapt the feed tower, which It transports the lids inside the oven, to the different sizes and shapes thereof, achieving greater versatility of oven operation.
- Some drying furnaces consisting of heating elements for drying the parts that are internally transferred thereto are known in installations for heating of coated metal parts by means of a transport mechanism consisting of a rotating frame having housing plates for the pieces, being provided with the control means that regulate the temperature and heating time, as well as a rotating frame drive device and an internal lifting mechanism to the drying oven.
- Other drying ovens have a ribbon Conveyor inside it to move the metal parts during the drying operation.
- furnaces that have opposing conveyor spindles, provided with grooves between which the lids that rise by the rotational movement of said spindles to the upper area are located.
- the covers are moved to the two lower spindles, which also cause the sliding of the covers with downward movement to the outlet.
- This system presents the problem of the obstructions that occur in the upper area when the covers are passed, from the spindles to the ones of descent, as well as the problems derived from the friction that the covers have in their movement. It is also noteworthy the vibrations caused during the operation of the device, and the difficulties posed by having a continuous power system.
- the solution is to mount fixed buckets, of reduced contact surface, to a rotating device, in such a way that the lids of the cans are fastened on the buckets, making possible a more uniform drying of said lids.
- this rotating device is positioned so that the distance between the buckets remains constant, making it possible only to dry the lids of the cans. same dimension.
- the present invention tries to solve the aforementioned problems by adopting a series of modifications with respect to the systems currently in existence, which allow to achieve drying of the lids for cans of different sizes and shapes, with a controlled drying time that makes it possible to obtain the pieces with a better finish.
- the proposed invention consists of an oven whose mission is the drying of the can lids, after being subjected to the operation of varnishing or coating with liquid rubber, consisting essentially of a mechanism to regulate the extension in width of a tower of feeding in which the covers are transported. Said covers remain fixed, without sliding, on movable supports by the action of drag chains to which they are linked, being able to avoid with this mechanism the frictions and vibrations that are generated in other devices.
- the pinions are provided with an inner opening in which some bushings are arranged, which are associated with the spindle that regulates the distance between pinions, by means of locking pliers in the appropriate position according to the size of the covers that are to be dried.
- the extreme chains engage in both upper and lower sprockets, so that a movement of each chain is established according to a closed cycle, determining a solidarity displacement of each of the buckets associated with the chains according to said cycle.
- the lids that are introduced through the oven inlet are placed in the corresponding buckets sequentially, one by one, then being moved in upward vertical direction until reaching the sector in which the upper gear pinion is located, where they make a rotating movement, to subsequently descend in a vertical direction until reaching the level of the output conveyor belt, being deposited on it that then moves them outside the oven.
- Figure 1. Represents a view of the drying oven with the internal situation of the power tower and the different transmission elements.
- Figure 2. represents a front view of the covers arranged on the three-channel buckets.
- Figure 3. Represents a side view of the three-channel buckets located on the chain.
- Figure 4.- represents an elevation view of the buckets of a channel.
- the drying ovens of covers for varnished cans consists of a feeding tower in which the lids of the cans (1) arranged on buckets (2) linked to the drag chains are moved (3) that engage in upper (4) and lower (5) sprockets, these sprockets facing each other and being movable to spindles (6) and (7) respectively arranged internally to said sprockets, to which they are engaged in the position which determines the distance coinciding with the length of the covers (1) that are intended to dry.
- the upper sprockets (4) move outwards or inwards depending on the rotation provided to the spindle (6), until it is fixed in the desired position the pinions (4) to the spindle (6) by means of a clamp locking system.
- the distance between the upper sprockets (6) will coincide with the distance between the lower sprockets (5).
- the metal buckets (2) that carry the covers (1) are presented in two possible configurations, one of them with four longitudinal flanges that define three internal channels in which the covers are placed that are smooth, and another variant (2 ' ) consisting of a bucket with a single adaptable channel to support double bottom lids.
- Each of the buckets (2, 2 ') has holes for passage of screws connecting the buckets with the conveyor chain (3).
