Definitions

  • the present invention relates to the unpacking of glass or plastic containers.
  • the invention relates more particularly to a new process for the disassembly of glass or plastic bottles as well as a new device for the implementation of this process.
  • Empty bottles are generally delivered or stored in crates or racks from where it is necessary to extract them for filling to align them on the conveyor feeding the machines.
  • the bottles are placed in the boxes at the place, that is to say with their neck oriented towards the top of the box.
  • a device equipped for example with inflatable tubes which are introduced between the necks simultaneously grips all of the bottles to place them on the conveyor of the filling line.
  • French patent publication 1 137838 describes a method and a device for releasing objects ligated together. In this process, we start from a set of bottles stacked horizontally in two beds which have already been rotated 90 degrees. Each bed is rotated 90 degrees in different directions to arrange all the bottles on their bottom.
  • the boxes can contain, when the shape of the bottles is suitable, not only a bed of bottles arranged at the place, but also a second bed of bottles inserted in staggered rows in reverse, that is to say with their neck oriented towards the bottom of the case. So, for example, we can have cases containing 39 bottles, namely a first bed of 6 rows of 4 bottles, which makes 24 bottles at the place and a second bed of 5 rows of 3 bottles, which makes 15 bottles staggered upside down, each of these being placed between 4 bottle necks on the right. Many other combinations using this type of storage are possible.
  • gripping means such as suction cups which grip the bottom of the bottles, then holding means which surround the seized bottles and turn them over to place them on the filling line conveyor.
  • This device has several drawbacks. It is bulky. It only works effectively when the bottom of the bottles is clean enough to be gripped by the suction cups, so it is necessary to clean these bottles before removing them from the crates.
  • US-A-3,777,913 describes a device for discharging an assembly formed by two container beds: an upper bed in which the containers are arranged upside down and a lower bed in which the containers are arranged upright , the necks of the containers of the upper bed being perpendicular to the necks of the containers of the lower bed.
  • the device described in this patent comprises a pivoting frame equipped with suction cups. In operation, the frame is placed above the containers of the upper bed, these containers are then gripped by the suction cups and returned while the containers of the lower bed not grasped remain in place.
  • the invention proposes a new automatic method of disbonding bottles, this term bottle being taken in the general sense of containers of the bottle type, arranged upside down in cases or racks and this whatever their state of cleanliness.
  • the disbursement according to the invention is rapid.
  • the device which implements it takes up little space and is easily integrated into a filling line.
  • the crate full of bottles is grabbed, it is turned over while retaining on the one hand the first bed of bottles arranged in the place in the crate, on the other hand the second bed of bottles arranged at the upside down, then this second bed of bottles is released while continuing to hold the bottles of the first in the crate.
  • the box is again turned over, which now contains only the bottles initially placed at the location, which is then disbursed in a known manner, for example using a frame equipped with inflatable tubes.
  • the box to be returned is generally entered at a standstill in a horizontal position. It can be entered at the level of the box conveyor or more advantageously at a higher level, after having been lifted for reasons of simplification of the device for the implementation of the method.
  • the invention also relates to a device for the disbonding of bottles arranged upside down, between the necks of bottles arranged upright, in a case or rack.
  • the device comprises means for lowering the second bed, comprising a gripping head provided with several grids allowing or blocking the passage of bottles according to their position, which hold the first and second beds of bottles in the box during the inversion, and which after inversion release the bottles of this second bed downwards, and means for inverting the gripping head around a preferably horizontal axis, and means for disbursing the first bed bottles.
  • the grids of the gripping head have a structure and an arrangement such that they can fulfill several functions and in particular a function of holding all the bottles in the box during the inversion, a function of releasing the bottles initially arranged upside down and at the desired time.
  • the gripping head of the device comprises a metal frame forming a support and two grids each having the same number of holes, of the same diameter and distributed in the same way, an intermediate grid, sliding in the metal frame, and a lower grid that can fulfill the role of centering of the gripping head on the body and also being able to keep the bottles upright.
  • the sliding grid can fulfill in this embodiment a function of holding the bottles upside down or on the contrary it allows their passage, this depending on the position it occupies with respect to the lower grid.
  • the metal frame forming a support in the gripping head is replaced by a grid subsequently called an upper grid, having the same number of holes as the other two, these holes being arranged in the axis of the holes in the lower grid.
  • the upper grid exerts a lateral holding function and guides the bottles during removal.
  • the gripping head in its horizontal gripping position, does not hinder the possible circulation of the boxes on the conveyor and is located at a level higher than that of the boxes on this conveyor.
  • the device then comprises an elevating member which brings this box to the level of the gripping head to allow it to be taken up by it.
  • the device according to the example is used for the disbonding of a maximum of 15 bottles arranged upside down, between the necks of 24 bottles arranged upright. It applies to the unpacking of bottles arranged on the spot. It applies to the disassembly of bottles arranged regularly, in contact with each other and whose barrel is of rounded shape. It applies for example to the disbursement of curved bottles such as ORANGINA bottles (ORANGINA being a commercial name).
  • the device is shown as a whole, vis-à-vis a conveyor 1 for supplying cases 2 full of bottles, in the gripping position of a case.
  • the conveyor 1 can be slightly inclined and equipped with idle rollers 101, so that the boxes move by gravity.
  • the conveyor comprises two guides 102 and 103 arranged above the rollers, which ensure the lateral positioning of the boxes.
  • the device has a metal frame 3 carrying two bearings 4 in which rotates a horizontal turning shaft 5 controlled by a rotary actuator 104.
  • On the horizontal shaft 5 are fixed arms 6 supporting the gripping head 7 described in detail by the after.
  • the figures show the gripping head in the gripping position of the box 2 to be returned.
  • the turning shaft is linked to the end of a crank 8 by a coupling sleeve 9.
  • the other end of a crank 8 is fixed to the rod 10 of an inclined jack 11 called a balancing jack fixed to the frame, which compensates for the weight of the body during the inversion of the gripping head.
  • the gripping head comprises three superimposed grids, each of them having 15 holes corresponding to the passage of the 15 bottles arranged upside down in the box and which are to be disbursed.
  • the upper grid 12 forming a support frame supports on two opposite sides four gripping jacks 13 articulated around the horizontal axes 14 and whose rods 15 are connected to two gripping jaws 16 which, controlled by the jacks 13 at the time of gripping the box, are housed in suitable openings 17 presented by the box.
  • the lower grid 18 has a chamfer 19 a few millimeters wide, extending around the entire periphery of the grid, making it possible to center the body exactly on the gripping head.
  • the intermediate grid 20 slidably mounted to be eclipsable, is linked on one side to a stirrup 21 secured to the rod 22 of a jack 23 supported by the upper grid 12 forming a support frame.
  • This cylinder controls the movement of the intermediate grid which can move relative to the other two grids, so that the holes 24 can either be in the axis of the holes of the other grids to allow the passage of the bottles to be disbursed, or offset so that the solid parts of the grid partially block the passage formed by the holes of the others grids to keep the bottles to be disbursed in the box during the inversion.
  • the device according to the invention may also include an elevator 25 for the box to be grabbed.
  • This member can be formed of two T 26 which, in the rest position, are eclipsed in the conveyor and which, at the time of their use, rise between the rollers of the conveyor to come to support and raise the box to be turned over.
  • the downstream T is equipped with two plates forming stops 105 on which the boxes abut.
  • the two vertical rods 27 of the T are fixed to a cross member 29 secured to a vertical cylinder 29 of the rod, the end of which in the form of a yoke is linked to a horizontal axis 31 carried by the frame.
  • This cylinder controls the movement of the elevator which raises the body to the level of the gripping head.
  • the two rods of the T slides in vertical ball bushings 106 mounted on crosspieces of the frame 3.
  • the lifting member also comprises two vertical guide rods 32 screwed in their upper part on the horizontal parts, U-shaped for example, T and which slide in rings carried by connecting pieces 33 secured to the frame. These vertical guide rods maintain the T-rods in a transverse position relative to the conveyor.
  • the device can also advantageously have a sheet metal cover 34 covering the path of the gripping head during turning. This prevents bottle or liquid splashes in the event of an incident.
  • FIG. 4 represents the upper grid forming a support frame, essentially formed by a metal plate, for example made of duralumin about 20 mm thick.
  • This plate is pierced in its central part 35, thinned by approximately 5 mm, with 15 countersunk holes 36 whose axes are spaced apart by the same spacing d, for example 83 mm, each hole having a diameter of approximately 79 mm .
  • the grid also has oblong holes 37 for attaching the gripping cylinders 13, not shown here, on axes to be placed in the holes 38.
  • the two sides along the width of the plate have a suitable cutout and holes 39 for their attachment to the arms 6, not shown here, supporting the entire gripping head.
  • Other bores 40 are provided for the passage of the axes of rotation of the two gripping jaws.
  • FIG. 5 represents the lower grid formed essentially by a metal plate, for example made of duralumin approximately 20 mm thick, pierced with 15 countersunk holes 41 whose axes are spaced apart by the same spacing d, as in the upper grid.
  • the dimensions of the lower grid are a function of those of the box to be returned, and, in this example, its outer cut into notches 42 and the dimensions of these correspond to a particular structure of this box to be returned.
  • This grid has over its entire periphery a chamfer 19 which is used for centering the gripping head on the body to be gripped.
  • the figure shows the sliding intermediate grid 20 formed essentially of a metal plate, for example of steel 4 mm thick.
  • This grid is pierced with 15 countersunk holes 43 spaced from each other by a spacing d.
  • the diameter of the holes is identical to that of the holes of the two other grids previously described.
  • the grid 20 has, on one side, two tongues 44 each pierced with two holes 45 for fixing to the control bracket 21 not shown here. Its dimensions allow the intermediate grid to slide between the two external grids in the thinned region of the upper grid.
  • This intermediate grid is shown in Figure 4 in phantom in offset position, that is to say in its position when gripping the body and when it is turned.
  • the operation of the device is as follows: The device is placed in the gripping position, that is to say with the gripping head arranged horizontally above the conveyor 1 for supplying the boxes.
  • the intermediate grid is in an offset position with respect to the other two grids whose holes are in coincidence.
  • the first crate is identified by a detector which activates the jack 29 which raises the elevator until the stops 105 appear above the level of the rollers, the T remaining overshadowed between the rollers. This intermediate position is maintained until the box comes into contact with the stops 105. During this time the following boxes are blocked by an annex transverse stop.
  • the cylinder 29 is then actuated a second time, which causes the two T-shaped rods of the elevator to rise.
  • the horizontal parts of the T's come into contact with the bottom of the box then lift the latter to come and place it facing the gripping head. Precise centering of the body on the head is effected by the external chamfer 19 of the lower grid 18.
  • the jacks 13 of the gripping jaws are actuated and the latter close on both sides of the body, partly engaging in the two lateral openings 17 presented by the body. This operation completes the body approach movement. In the gripping position, the bottles are generally not in contact with the lower grid.
  • the rotary actuator 104 is actuated which causes, around the turning shaft 5, the turning of the box, which, initially arranged along the axis A, is then placed along the axis B.
  • the bottles of the second bed initially arranged upside down, come under the effect of their weights engage in the openings of the lower grid. Thanks to the arrangement of the holes of the lower grid separated by a distance d greater than the diameter of the bottles and also thanks to the partially rounded shape of the barrel of the bottles, the latter deviate slightly from each other during the inversion, l 'thickness of the lower grid being sufficient to allow the spacing of the bottles.
  • the bottoms of the bottles of the second bed initially placed upside down abut against the solid parts of the offset intermediate grid.
  • the bottles of the first bed initially placed at the place abut by their neck on the solid parts of the lower grid 18.
  • the actuator 23 is actuated which causes the sliding of the intermediate grid 20 in the thinned part of the grid 12 now placed downwards.
  • the sliding of the intermediate grid has the effect of placing its holes in the axis of the corresponding holes of the upper grid and the lower grid.
  • This has the effect of releasing the bottles from the second bed initially placed upside down and which, after having been guided by the holes in the upper grid, are found by turning upside down arranged on the moving evacuation conveyor. This then drives them, for example, to the filling station while, by the action of the rotary actuator 104, the box is again turned over again still containing the bottles of the first bed initially placed at the location.
  • the body returns in axis A, above the elevator.
  • the jacks 13 are actuated, the rods of which push the gripping jaws which release the box.
  • the elevator is lowered which deposits the box on the conveyor rollers.
  • the latter driven by its weight, goes towards the station for disassembling the bottles from the first bed arranged at the place.
  • the device can be fitted with a jack, the role of which is to give the necessary impulse to start the box.
  • the disassembly of the bottles from the bed arranged at the place is then carried out in a known manner, for example by using a device equipped with inflatable tubes.
  • the detector having identified the distance from the first box triggers the movement of the next by releasing it from its stop.
  • the total duration of the operation according to the invention is of the order of a few seconds. We therefore process approximately 6 to 10 cases per minute.
