Description

DEVICE FOR GENTLE TRANSFER AND SOFT STORAGE OF FRUITS OR VEGETABLES

description

The invention relates to an improvement in a known device which consists of two successively arranged conveyor belts for the transfer and storage of fruits or vegetables on a fixed or moving plane or within a container.

The aforesaid devices consisting of a horizontal

Feed conveyor belt and a vertical conveyor belt which forms a vertically adjustable filling head and are used on various machines, e.g. in the processing of apples, for filling crates or large crates or on apple harvesters for filling the crates during the advancement of the harvester between the rows of trees.

From US 4,194,343 a device for the soft filling of large crates is known which uses rows of mutually protruding brushes on mutually parallel conveyor belts. The filling head moves, in

Dependence of level reached, vertically within the large box, while it is alternately moved back and forth in a horizontal plane to deposit the product in even layers. Characterized in that the product is held in the interior of the filling head between two vertical, mutually parallel band sections, wherein it

Receiving area between the horizontal rows of brushes, which protrude against each other from the parallel, synchronously running tape sections, the size or diameter of the machinable product depends on the distance between the two parallel tape sections. In the region of the exit from the filling head, the product rests on an oblique plane and becomes elastically deformable elements which protrude against this plane braked. The four band sections of the two conveyor belts which occupy the cross section of the filling head take up much space, so the filling head takes up space. The fact that one of the conveyor belts which vertically pass through the filling head also serves as a feed belt, must for the tension of this band during the vertical movements of the

Filling head, a space-consuming tensioning mechanism with a

Be provided swivel arm. The said tensioning mechanism requires at least three pulleys over which the belt runs with the brush side, whereby noise and vibration are generated and frequent maintenance is necessary.

This device is unsuitable for products with very different sizes or very different diameters, furthermore heavy products can not be securely held by the opposing elastic brushes during their transfer down.

From EP 0040293 A1 is a system for the uniform filling of

Large crates with fruits or vegetables known. The product is introduced through a conveyor belt without receiving troughs or transverse shafts to the filling head. The filling head, which is moved vertically depending on the filling level inside the large box, is provided with a single conveyor belt which is driven by its own motor (105), this is not connected to the drive of the feed belt, which has its own motor ( 106) which also drives an inclined conveyor belt at the exit of the filling head. Because of the features of the feed belt which consists of two opposing belts with diverters to act as a memory, this device is not suitable for harvesters where on the

Feed belt usually individual product pieces and these are laid out at intervals and where this band often because of the soil texture a

occupying a rising or falling position. This device does not have a synchronization between the feeding belt and the filling belt because the feeding is not done by means of receiving troughs or transverse shafts and thus not in individual pieces or in "portions", which synchronizes with the Would require shooting areas on the vertical band. When the product is transferred from the feed belt to the vertical belt, it therefore often hits the ends of the projections projecting from the vertical belt, thereby damaging it.

From EP 0275602 A1 a harvesting machine is known which has two pivotable arms with feed conveyor belts which transfer the harvested product to two vertical filling belts within vertically movable filling heads. The said horizontal feed belts do not have receiving troughs or transverse grooves for receiving individual ones

The horizontal and vertical belts are driven centrally by a single engine reduction gear unit with a different gear ratio for the horizontal and vertical belts is limited by the fact that the horizontal band in contact with the

Projections of the vertical band comes and thus this elastic bends downwards (Division 5, lines 33 to 36). From JP S51 33470 A is known a transport device for the packaging of eggs which makes use of several conveyor belts which are all driven by a single motor and, concerning the

Recording areas with different distances at the different bands, are synchronized. The vertical transfer of the product is not done by means of a vertically adjustable band therefore this device is not suitable for the uniform filling of containers.

From US 2,889,676 there is disclosed a machine for filling cartons, e.g. known with lemons. The machine has a feed conveyor belt with rotating rollers and a vertically movable filling head with vertical

Trough transport belt with swiveling containers on. The belts are driven and synchronized by a single motor, the products can be used at the same time Changing over from the feed belt to the vertical belt will be damaged because there is always a certain free gap between them.

Practice has shown that, during the passage of the fruit or vegetables on the two conveyor belts and during the storage of the fruits or vegetables, they are exposed to stresses such

Pressure marks and damage which affect the saleability and the durability of the products.

The said harmful loads occur in two areas:

a. in the area of Überwechseseins supply band, which is usually arranged obliquely or horizontally and, for the reception of fruits or vegetables, transverse waves or depressions, on the vertical bar equipped with rungs, which is vertically adjustable to the growing level of in one To be able to adapt containers of stored product;

b. in the area of the exit from the vertical band where the transfer of the product from the vertical band to a rotating brush for the purpose of controlled transfer and storage of the product takes place.

In the first, under point a. Area mentioned, also damage takes place when the two bands, even taking into account the vertical movement of the filling and the possible pivoting movement of the feed belt are synchronized so that the product leaves the wells of the feed belt, although not directly on the shoot tips of the second vertically adjustable Bandes meets. This damage occurs because between the two conveyor belts in the transfer area, despite synchronization, always a free gap remains and, falling from the trough or transverse product in the area of this free gap can impinge on the shoot tips of the vertical band or even with a narrow part, such as him eg Having pears or bananas, can penetrate into the gap causing pressure points; this damage occurs more frequently when, e.g. Fruits in the transverse waves of the

Zuführbandes occupy a superimposed position and thereby the

At the same time leaving the crosswave does not find enough free space around individually and gently to be able to roll or slide into the corresponding receiving area of the vertical band.

In the second, at point b. However, the area is caused by the fact that the product by gravity leaves the receiving area between projecting from the vertical band sprouts as the corresponding row of sprouts moves around the lower pulley to continue the movement vertically upward, the product in a known manner on an inclined plane in the direction of a rotating brush

horizontal axis of rotation rolls, but there is a risk to hit the tips of the arranged in rows and radially projecting bristles of this brush. This takes place because the said brush is mounted on arms which project from the lower end of the frame of the vertical band, the arms being pivotally mounted coaxially with the axis of rotation of the lower pulley of the band and moving with respect to the pivotal position of a lower support panel Gaps between the radially protruding bristle rows do not always correspond to the receiving areas between the rows of rungs of the vertical band. The object of the invention is to avoid damage to the product which takes place during the crossover from the feed belt to the vertical conveyor belt and from this vertical belt to the rotating brush. To solve this problem, the invention proposes to reduce the free gaps in the transfer area between the feed belt and the vertical conveyor belt and provide at least one adjustable or rotating element by which the product pieces emptied from the feed belt are gently absorbed and find enough space to not overlap State to be supplied to the corresponding receiving area on the vertical conveyor belt, while at the bottom of the

Filling head a synchronization of the rotating brush with the vertical Conveyor belt is proposed so that the emptied from the vertical conveyor belt product pieces can take the receiving area between the radially projecting bristle rows on the brush without obstructions. Both conveyor belts of the device are driven in a known manner via a single motor unit with reduction gear which acts on the drive roller and is connected by means of a toothed belt or chain with the drive roller at the lower end of the vertically adjustable vertical band.

According to the invention is on the same axis of said drive roller a

Pulley or a gear for a toothed belt or a chain constructed which transmits the movement to the, on the same axis of the drive roller pivotally mounted, brush.

To the vertical adjustment of the filling head with the vertical

To allow conveyor belt while maintaining the required synchronism with the feed belt, runs the drive toothed belt, which is supported by a drive pulley which is mounted on a, connected to the frame of the machine, side wall and by the single group consisting of motor with reduction gear, in a known manner via two, mounted on the same side wall, Umlenkriemenscheiben

then to run over the pulley which with the axis of the

Drive roller is connected to the lower end of the frame of the vertical conveyor belt and to run over a deflection and tension pulley which at the upper end of the frame of the vertical conveyor belt

are provided. By the above-mentioned arrangement of the toothed belt for driving the vertical conveyor belt is achieved that, by the vertical known adjustment of the filling head with the vertical conveyor belt, a rotation of the drive roller of said belt, takes place in that during said adjustment, the respective lengths of the belt section between the upper Umlenkriemenscheibe mounted on the side wall and the upper mounted on the frame of the vertical conveyor belt

Pulley and the belt section between the lower at the Sidewall mounted deflection pulley and the lower

Timing pulley, which on the axis of the drive roller of the vertical

Conveyor belt is constructed to be mutually complementary. This rotation, in the opposite direction, in response to the upward or downward movement of the filling head with the vertical conveyor belt, superimposed on the drive movement of the vertical conveyor belt during acceleration and during the downward movement, a slowing down. These said changes in the movement of the conveyor belt effect in a known manner, the maintenance of the association between the receiving areas (transverse waves or troughs) on

Feed conveyor belt and the receiving areas (between the projecting rungs) on the vertical conveyor belt, even during its vertical

Adjustment. The rotating brush experiences, during pivoting of the respective arms coaxial with the drive roller on the filling head with the vertical

Conveyor belt, with respect to the pivoting direction, a rotation which superimposes the drive rotation, which is achieved according to the invention that, in any position adopted by the brush pivot position, the receiving areas for the product on the vertical conveyor belt correspond to the receiving areas between the radially protruding bristle rows on the brush, whereby the Transfer of the product without obstacles takes place.

Of course, the association between the, at the individual transport organs (feed conveyor belt, vertical conveyor belt, brush) of the device

receiving areas are set during their assembly, wherein the product freely rolling or sliding distances covered on inclined surfaces, which between the Zuführtransportband and the vertical

Conveyor belt, as well as between this and the brush are provided, are taken into account. According to the invention, the inclined surface is formed in the transfer region between the feed belt and the vertical band of an adjustable in the slope and position element whose inclined surface with elastic

Foam, fabric or bristles is coated, the conveyor belts facing sides of this surface may be elastically deformable or provided with elastic bristles or strips which may be on the

Transport belts abut or interfere with these and are elastically deformed. This said element with the inclined surface can be replaced according to the invention by at least one rotating brush or a profiled or cylindrical, soft coated roller which can also be in both cases with the vertical conveyor belt or with both belts in contact or interfere, the rotation of these brushes or rollers may be synchronized with the belts or by a separate motor, with the ability to change the speed independently of the conveyor belts to slow down or accelerate the changeover of the product pieces.

The invention will be explained in more detail with reference to a preferred embodiment of a device according to the invention for the gentle transfer and the gentle placement of fruits or vegetables schematically illustrated in the attached drawings; The drawings fulfill a purely explanatory, non-limiting purpose.

Fig. 5a is a vertical sectional view of the lower part of the vertical conveyor belt with pivoting brush and lower pivotable

Supporting panels. The device for the transfer and storage of fruit or vegetables consists essentially of a feed conveyor belt 1 with transverse shafts or troughs 1 a, 1 b with frame, from a vertical conveyor belt 1 with belt 2 a with protruding rungs 2 x and 2 b frame and from a rotating 3 r Brush 3 which is constructed on at least one pivotable 3c arm 3b. The

Feed conveyor belt 1 runs for 1 s via a drive roller 1 r and an idler roller 1t, which are mounted on the frame 1 b, this is fed, e.g. loaded via an introduction device 1 c at the free end of the frame 1 a with fruits or vegetables, the deposited product F is distributed by gravity, according to rows transverse to locomotion 1 s, in the troughs or transverse waves 1 a of the conveyor belt. The frame 1 b is at the end which is opposite to the loading area between side walls 1 d, coaxial with the axis of the drive roller 1 r, 1w pivotally mounted, these are firmly connected to the frame of the machine and also serve for the known vertical sliding 2v storage of the filling head for The vertical conveyor belt 2. Both side walls 1 b are fixed to the frame of the harvester or the fruit processing machine, while the feed belt 1, in particular to harvesters on these side walls pivotally 1 w is mounted to compensate for any inclinations in the busy terrain can. On one of these side walls 1 d is the outside

Drive unit, consisting of motor with reduction gear M, constructed which drives the, provided on the inside of the side wall, gear 1 m, this meshes with a gear 1 n which the drive roller 1 r of the

Transport belt 1 drives. The said gear 1 n combs further with the gear 1 p which is coupled to a toothed belt pulley for a toothed belt 2w, which via two pulleys 1f, 1 g, via an idle, at the upper end of the frame 2b of the vertical conveyor belt mounted, pulley 1z and via a toothed belt pulley 2u at the lower end of the frame 2b, which runs on the shaft of the drive roller 2r of the vertical conveyor belt 2 is constructed. The Umlenkriemenscheiben 1f, 1 g are mounted on the inside of the side wall 1 d.

The frame 2b of the conveyor belt 2 is vertically slidably mounted 2v and driven by a motor which is controlled in a known manner via a probe which is mounted below its own, independent of the support panel 3g at the lower end of the frame 2b, 3f pivotal panel 3e. The conveyor belt 2 is equipped with projecting elastic rungs 2x which occupy a direction opposite to the direction of angled position and are arranged in horizontal, spaced apart, rows to form between them, receiving areas 2a for the products F.

At the lower end of the frame 2b of the vertical conveyor belt 2, the products F move from the rungs 2x over the support panel 3g, rolling or sliding in the direction of rotating 3r brush 3 with radially protruding bristle rows 3x so that the product F in receiving areas 3a between the rows of bristles is received and moved in the direction of the protruding edge of the support panel 3g. This brush 3 is mounted on at least one coaxially to the drive roller 3r of the vertical conveyor belt 2 pivotable 3c arm 3b. An abutment prevents the arm 3b from being lowered too far so that the brush 3 does not contact the support panel 3g while the upward pivoting is free and possibly influenced by gravity or by a spring.

The synchronization system which operates between the feed conveyor belt 1 and the vertical conveyor belt 2 and the rotary brush 3r 3 always, even during the vertical movement 2v of the frame of the vertical

Transport belt 2, during the pivoting movement 1 w of the feed belt 1 and during the pivoting movement 3c of the rotating 3r brush 3, the assignment between the receiving areas 1 a - 2a; 2a - 3a for the transfer of the products F, so that these, during the change of one

Transport organ on the next, always find the following receiving area in the receiving position, the collision with the tips of the sprouts 2x, or with the tips of the bristles 3x, is avoided. This is achieved by the already mentioned, centralized controlled drive of all the individual transporting members 1, 2, 3 for the product F, by the mechanical drive for the transmission of the movement to the vertical conveyor belt 2 and to the rotating brush 3.

In the transfer area A between the feed conveyor belt 1 and the vertical conveyor belt 2 according to the invention an element with oblique surface 1 e is provided which, in terms of inclination and position, with respect to the

said conveyor belts is adjustable. The oblique, soft coated

Surface 1 e allows the product pieces F free in the direction of vertical

Roll or slide conveyor belt. The, the conveyor belts 1, 2 facing sides of the inclined surface 1 e are preferably made of elastic material, with a series of elastic bristles or with elastic protruding

Plastic strips provided and can touch the conveyor belts or interfere with these, with deformation of the bristles, the elastic coating or the elastic protruding strips to create a "seamless" transition to the conveyor belts 1, 2.

The element with inclined plane 1 e can be replaced according to the invention by at least one rotating brush 1 1 e or a cylindrical or profiled roller 12 e. The roller 12e is preferably with elastic Schaustoff, with

coated elastic fibers or protruding bristles. Be it the brush 1 1 e, as well as the roller 12e, both conveyor belts, or even the vertical conveyor belt 2 tangentially touch or with this, with deformation of the bristles, or the elastic coating or the elastic protruding strips interfere to the for Product pieces F to create a "seamless" transition.

The invention does not exclude that the above-mentioned rotating brush 1 1 e or rollers 12 e are arranged together with an element with an inclined surface 1 e. The rotation of the brushes 1 1 e, or rollers 12 e, with the

Synchronized conveyor belts or via its own drive and, regarding the peripheral speed, made adjustable. The well-known mechanism for the permanent synchronization of the movements of the conveyor belts 1, 2, even during the vertical

Adjustments 2v of the vertical conveyor belt 2 and the pivoting movement 1w of the feed belt 1 is characterized by the course of the toothed belt 2w for transmitting the movement to the vertical conveyor belt 2 on the two, spaced apart, at one of, with the frame of the harvesting vehicle or the processing machine firmly connected, side walls 1 d stored rollers 1f, 1 g running, by the course on the shaft of the drive roller 2r mounted pulley 2u and the idler pulley 2z, which are mounted spaced from each other, each of them at one end the frame 2b of the vertical conveyor belt which is vertically slidably guided 2v between the side walls 1 d. This mechanical drive causes, during the vertical adjustment 2v of the vertical conveyor belt 2 and the pivoting movement 1 w of the feed conveyor belt 1, such an influence on the motor M via the toothed belt 2w outgoing

Drive movement that the mutual association between the

Receiving areas 1 a, 2 a for the product F at the two conveyor belts 1, 2, in the transition region A from one band to the next, is secured. The mechanism for the permanent synchronization of the movement 2s of the vertical conveyor belt 2 with the rotation 3r of the brush 3, also during the pivoting movement 3c of the brush 3, is characterized according to the invention in that the pivotal movement 3c is coaxial with the shaft of the drive roller 2r of the vertical conveyor belt 2 and in cooperation with the transmission of the movement by means of toothed belt 3w from the toothed belt pulley 3t, next to the pulley 2u, onto which, mounted on the shaft of the brush 3,

Timing belt pulley 3u, wherein both are mounted on the pivotable 3c arm 3b, the first 3t coaxial with the toothed belt pulley 2u and the drive roller 2r and the second coaxial with the shaft of the brush 3. This arrangement causes a

Influencing the rotation of the brush 3r 3r depending on the width of the angle of the pivoting movement 3c and their direction, always being the perfect

Assignment, between the receiving areas 2a for the product F at the vertical Conveyor belt 2b and the receiving areas 3a between the rows of bristles 3x on the brush 3, is secured.
