Definitions
- the stacks are generally conveyed on a horizontal line that is preferably constituted by belts being closed in a loop and wound around pulleys.
- Such feeders have a drawback related to the positioning of the stacks in the holding station at the output of the line: when a stack arrives at the output and leaves the belts, it tends by gravity to break up or tip, arranging itself incorrectly in the holding station and making it difficult to transfer the trays toward the subsequent processing stations.
- the aim of the present invention is to obviate this drawback by providing a feeder that allows to deposit the stacks of trays correctly and tidily at the output, thus facilitating transfer to the subsequent processing stations.
- an object of the present invention is to provide a feeder that is versatile and flexible, i.e., adapted to transfer effectively, from one station to the next, stacks of trays having different shapes and dimensions.
Abstract
Description
Claims (7)
- A feeder for trays packed in vertical stacks, comprising a conveyance line (2a) with belts (6, 7) that has, at its output, a subsequent station where said stacks (4) are deposited, characterized in that it comprises support, transfer and retention means (15) that are adapted to support the base of each one of said stacks (4) as they leave said conveyance line (2a).
- The feeder according to claim 1, characterized in that said belt-type conveyance line (2a) comprises at least two parallel belts (6, 7), which are closed in a loop and form a horizontal active upper portion for conveying said stacks (4) between two opposite shoulders (10, 11).
- The feeder according to claims 1 and 2, characterized in that said support, transfer and retention means (15) comprise two horizontal bars (16) that are parallel to said belts (6, 7), can be actuated by translational motion means (17) so as to advance from a retracted position to an extended position in which they protrude beyond the output (5b) of said conveyance line (2a) in order to support said base of each one of said stacks (4) as it leaves, and can be actuated so as to perform a backward translational motion from said extended position to said retracted position during the step for depositing said stack (4), so as to allow the descent of said stack (4) by gravity.
- The feeder according to claim 3, characterized in that said support, transfer and retention means (15) comprise a pusher (18) that is associated with linear actuation means (19) and can perform a translational motion from a first position, in which it lies below the conveyance plane of said stacks (4), to a second position, in which it is engaged in a rear region on said stack in order to push in the advancement direction, allowing said stack (4) to leave said conveyance line on said bars (16), said pusher (18) constituting an abutment for said stack (4) during the backward translational motion of said bars (16) in order to allow the correct positioning of said stack (4) in said holding station.
- The feeder according to claim 3, characterized in that said translational motion means (17) comprise a first double-acting linear pneumatic actuator (20) that acts along a direction that is substantially parallel to the advancement direction of said stacks (4), its stem (21) being rigidly coupled to the centerline of a plate (22) that has, at its opposite ends, holes (23) for fixing said bars (16).
- The feeder according to claim 4, characterized in that said actuation means (19) comprise a second double-acting linear pneumatic actuator (25) that acts along a direction that is substantially inclined with respect to the advancement direction of said stacks (4) and in which the end portion of the stem (28) is connected to said pusher (18).
- The feeder according to claims 4 and 6, characterized in that said pusher is constituted by a front plate (29) and by a rear plate (30), which are connected along their respective upper edges and are monolithic, in a downward region, with an L-shaped element (31) for fixing to the stem (28) of said second pneumatic actuator (25), said front plate (29) having a cambered profile that is adapted to apply a thrust that has a component in a substantially horizontal direction to the rear of said stack (4), so as to make said stack (4) leave said conveyance line (2a).
