The present invention relates generally to an apparatus for grouping objects example od bottles. The like., Which are to be detected by a system for packing and unpacking in or ₀ of a box, said installation comprising a plurality of seconded equidistant gripper heads are each provided with rows of gripping organs and move along at least one straight section of the track at a constant speed »

109850/1004

This device consists of a horizontal longitudinal conveyor, the below the straight track section with a constant Speed, which is higher than that of the gripper heads, moved and from several separate Elements that are built on a rotating drive system are and each take a row of bottles, from a device for guiding the bottles, which in a vertical position arranged to the straight track section and with retaining members is provided, which are at the same distance from each other and according to a Pitch L, which is equal to the pitch of the heads, are arranged and moving at a speed V equal to the speed of the Gripper heads corresponds to, move, as well as selectors which are arranged to move upwards in relation to the guide device

k to group a certain number of bottles in each row "

The bottles, which are randomly distributed on the elements of the conveyor, are first put together and, with the help of the selector, into uniform bottles Groups distributed; then every bottle group released by the voters is picked up by the guide device, and from here guided underneath the gripper heads so that the bottles are gripped by the gripper heads »

There are already known voters for grouping devices that temporarily hold back the bottles or the like, that is, those voters who cause an interruption in the movement of the bottles, causing bumps and thus the risk of breakage as well as a reduction in the possible throughput of the grouping devices Known voters who

for wrestling. Move speed than that of the conveyor and thereby brake the bottles. The mechanical connections between these selectors and the following guide means were not determined or described »· It follows that the guide means prevent the best possible operation of the grouping devices involved»

The purpose of the present invention is to enable the above-mentioned grouping devices to work in the best possible way. The grouping device according to the invention is characterized in that the selectors are provided with retaining members, which are arranged at the same distance from one another and according to a division] and move at a speed _ γ 1 »

The constituents of the voters move at a speed those of the restraint means of the guide device

109850/1004

within the ratio of the respective division of these restraint means is proportional, resulting in strict synchronization, a slight decrease in the speed of the bottles or similar objects and thus the best possible operation of the grouping device can be achieved

According to a further feature of the present invention, the voters comprise various separate selection devices which are arranged one after the other under the conveyor, the stops or groups of stops of each selection device located at the same distance from one another according to a respectively different division la, Ib, Ic, etc., and move at a certain speed _{= v} la · _{v Y} Ib _{v =} y Ic _{etc. # oo #} a Ib Lc L

Since the stops for each voting device with a predetermined

Division are distributed by the presence of several Various divisions made available for voting devices, i.e. " that this allows groups of bottles to be formed which differ in terms of the number of bottles and their diameter are designed «.

The known selection devices are also provided to accommodate a certain number of rows of bottles, each having a certain diameter, and for assembling these bottles into groups which _t besbehen each consisting of a likewise predetermined number of bottles ^ Ernrti.ge devices may therefore exclusively with gripper heads of a certain structure can be used, i.e. with gripper heads which have a certain number of gripping organs arranged in rows, these rows being spread apart from one another at a predetermined distance (which depends on the diameter of the bottles) and each being provided with a certain number of gripping organs This device is therefore very limited, although there are numerous designs of gripper heads that are adapted to the different types of bottles and bottle crates, so that these devices now allow the systems to be used by themselves m one or Unpacking bottles or the like in or out of a box.

Another purpose of the present invention is to facilitate the compilation and management of the bottles for their treatment to enable systems to be packed or unpacked into or out of a box, through systems that allow any number of Be able to grasp bottles with an indefinite diameter and with a gripper -

heads are provided, which are any number of rows arranged gripping organs, these rows with indefinite Arranged at a distance from one another and any number of such gripping elements are provided in each case.

The grouping device according to the invention is also characterized marked that the elements that are part of the conveyor in terms of their number and their mutual provision are adjustable, and in that the retaining members consist of groups of interchangeable stops, which on the one hand on the Guide device and on the other hand are detachably installed on the selector.

The conveyor according to the invention grouping device can therefore be provided with a number of elements which is the number of arrival% gripping member rows of gripper heads equal to the mutual spacing of these elements corresponds to the distance of the gripping member rows. In addition, since the restraint members of the voters and those of the guiding device are interchangeable, the voters and the guiding device can be provided with a set of restraining members that are adapted to the number of elements of the conveyor and their mutual spacing Gripping organs which are contained in every gripping organ row of the gripper heads, and which are adapted to the diameter of the bottles «.

In contrast to the known grouping devices, the grouping device according to the invention enables the treatment or the Handling of any number of rows of bottles, each of which has "any dimensions," does this with this device as well how the known gripper heads is generally applicable and that they no longer have any reason to limit the performance as well the applicability of the systems for input or. Unpacking bottles in or out of a box

According to a further feature of the present invention, the elements of the conveyor are provided by two ribbed drums carried, which have concurrent axes, lie in the same horizontal plane and longer than the useful width of the conveyor are designed so that these elements by lateral translational movement different positions with respect to the drums and each other can accept.

10 comprises several gripper heads arranged according to a division L

11 (two of which are shown), which with gripping organs 12 are provided, which each serve to grasp the bottles through their necks »The gripping organs 12 are in the illustrated ealin three rows each with four gripping organs distributed The gripper heads 11 are on sliders ^ built-in in which they can slide in the vertical direction, these sliding pieces in turn on two horizontally arranged endless chains 14 are installed, which are in engagement with two equiaxed pairs of sprockets 15a and 15b »Das Pair 15a is driven by a motor 16 through the transmission element 17 in Rotation offset »The gripper heads 11 are in a closed circle with a constant translation speed V of a path driven along which between the two pairs of sprockets 15a and 15b has two rectilinear sections, one of these sections, namely the front section, being above the grouping device 20 is located while the other section, viz

the rear via a (not shown) conveyor belt or the like., which is used to transport the boxes, is arranged.

The grouping device 20 comprises a horizontally arranged conveyor 21, which is made up of three but identical ones Elements 22 consists, which in turn are mounted on a rotating drive system, which consists of two on the frame 24 of the grouping device rotatably built-in drums 23a, 23b, the drum 23a being driven by the motor 16 with the aid of a chain transmission 25 is driven at a constant speed, the conveyor 21 is accordingly at a constant translational speed V,> V driven, with each element 22 of the conveyor being perpendicular Position to a corresponding gripping organ row of the gripper heads located.

The conveyor 21 is on the one hand with a device for guiding the bottles 30, which below the elements 22 and in a vertical position Position to the rectilinear section of the web is stored, as well as combined with means for selecting the bottles 40, which are connected upstream are arranged in relation to the straight track section »

The device for guiding the bottles consists of a system of endless chains 31, which by the motor 16 with the help a chain transmission 32 is driven at the speed V of the gripper heads. The chain system 31 is with retaining links 33 provided, which are distributed equally spaced according to a division L and in the spaces between the elements 22

109850/1004

each on both sides of these elements are arranged, the restraint eglieder 33 protrude beyond the horizontal plane of the conveyor.

The means for selecting the bottles 40 in the illustrated case comprise two selection devices 40a and 40b which, like the guide device 30, each consist of a system of endless chains 41a, 41b driven by the motor 16 with the aid of the transmission chains 42a, 42b at the respective Speeds ν and v- are driven, these speeds being less than V and consequently V ₁ . In the example shown, only the device 40a is provided with retaining members 43a, which are constructed identically to the retaining members 33 of the guide device 30 and are distributed equally spaced according to a pitch la. Similar to the retaining members 33, the retaining members 43a are in the spaces between the elements 22 and on both sides of the elements and protrude beyond the conveyor belts

For the sake of clarity in FIG. 1, only one set of retaining members has been used 43a shown.

The operation of the grouping device is explained below with reference to FIGS. 1 and 2. The bottles B are placed on the conveyor 21 according to three rows corresponding to the three elements of the conveyor, one after the other and with any distribution, that is, the distance between two consecutive bottles is arbitrary and is changeable. The bottles are carried along by the conveyor at a speed V _f, namely the speed of the conveyor, until the first bottle in the row hits the retaining element 43a of the selection device 40a, which is arranged below the conveyor.This bottle and the bottles behind it are forced in this way to proceed according to the speed ν of the relevant restraint member.

JEl

to move, where the speed ν is lower than the speed V. is so that the therefore braked bottles on the conveyor slide and be brought butt against each other. The division la of the retaining members 43a of the selection device 40a is chosen so that they corresponds to an integer number of bottles (i.e. that la ^ fc nD, where na represent the number of bottles and Da represent the diameter of the bottles separated by the selector 40a) “In this way, if the following retaining element comes over the conveyor, it is placed in the space between the η-th and the η + 1-th bottle (in the case shown between the fourth and the fifth bottle) and hold back all bottles from the η + 1-th bottle (in

109850/1004

the Pall shown from the fifth bottle). If the first bottle at the end of Nutzstrums the endless chain arrives 41a, pushes the retaining member, which retains this bottle can be returned so that released the four retained between two retention members bottles below the conveyor _o Thereafter it by the conveyor 21 at a speed V .taken. The selection device 40a distributes the bottles into separate, uniform groups of four bottles each - in the present case.

The group of four bottles moves with speed V. until they hit a retaining member 33 of the guide device 30 hits o The retaining members 33 move with the speed V of the gripper heads and are each in a perpendicular position to the front part of the gripper heads during their Bek movement on the upper run of the endless chain 31 that the group of bottles is placed exactly below a gripper head and moves at the speed of the gripper heads.

It goes without saying that the time required by a restraint element 43a of the selection device 40a to travel through the route la corresponds to the time which is required by a retaining member 33 of the guide device 30 to traverse the distance L. If ν is the constant translation speed of the

Tbsp

Retaining members 43a, denoted, it is said that: (1) ^ a = VxJS

The evolute of the chains of a selection device, such as 40a and the number of retaining members of this device are chosen so that "never less than one retention member or more than two retaining members come into position at the same time in which they come to the bottom of the bottles in contact ₀

In this way, the pushing action exerted on the bottles is always retained by a retaining member, which the conveyor only leaves when the next restraint member occurs »No bottle can then be taken without being in a group of bottles to be framed. On the other hand, since the division of the retaining members 43a is chosen so that it corresponds to an integer number of bottles, if the retaining element protruding above the level of the conveyor - Flawlessly incorporated behind the group of bottles which are currently will be left unsuccessful.

The three elements 22 of the bottle conveyor 21 can as on the

109850 / 100A

Figures 3 to 6 consist of chains with wings, 220, which are installed on guide rails 221 and are in engagement with two drums 23a and 23b, which in turn are provided with ribs over their entire length, so that these wing chains laterally i.e. concurrently with the axis of rotation can slide the drum in which they remain with the ribs of the drum is engaged _o in this way, one can arbitrarily adjust the distance between two consecutive wings chains, so that this distance is adapted to the diameter of the bottles and of course to the distance between the gripping organ rows of gripper heads · The length of the drum 23a and 23b depends on the maximum number of wing chains which are placed next to one another to form the conveyor 21. In the case shown, the length of the drum 23a and 23b is significantly greater than the useful width of the conveyor consisting of three wing chains 220. This makes it possible on the one hand to spread the chains more apart than is shown in the figure, whereby bottles with a larger diameter than shown can be transported, and on the other hand to add two or even three additional wing chains so that the grouping device no longer has three but five or six rows of bottles receives »

The provision of the elements 22 is achieved by means of rods 26 which are rotatably mounted on the frame 24 and are provided on their circumference with a number of flat spots 26a and 26b located in the same plane, which are mutually perpendicular. The flats of the same group as "26a are distributed according to a given pitch which z from the pitch of the flats of the other group _o B. 26 b differs ₀ The Beistellungsstangen 26 are the elements 22 of the Föderers provided for supporting the rails 221, each The pair of rails 221 is mounted in a flat spot, so that the three elements 22 are arranged with the desired spacing corresponding to the division of the flat spot group in question «

Assuming that the rails are supported on the flats 26a (as is the case in Figure 3) and if you want to change the distance between the three elements of the conveyor 21, it is sufficient to turn each rod 26 by 90 ° so that the flat spots 26b are brought into a horizontal plane, and the elements 22 to move sideways «. These elements were due to the rotary motion of the bar raised from a height which is the depth of the flats corresponds, and are supported on a generatrix of the rod 26, bia the rails 221 fit into the flat spots 26b, (Figure 4). During this translational movement, the move

Upholstered chains 220 on the ribbed drums 23a and 23b.

A locking device is provided for holding the elements 22 on a predetermined group of flats of the rod 26. This device in turn consists of a rod 27 provided with a flat spot 27a, which is installed so that it can rotate on the frame 24 and is in engagement with locking elements which are firmly connected to the rails 221 and consist of stops 222 which are fastened by means of the screws 223 Depending on whether the rod 27 is in the position shown in FIG the rails are locked or not _β the guiding device 30 and the selectors 40a and

W 40b are constructed identically, so that only the guide device 30 is described below, for example.

With reference to FIG. 7, it can be seen that the guide device 30 consists of two vertical, synchronous endless chains 31 which are in engagement with two Ketfcenrräderaaren 34a and 34b, which in turn are each firmly installed on a shaft 35a, 35b by one of these shafts A drive shaft is (35a for the guide device). Between the chains 31, a support 300 is provided for the exchangeable retaining members, which consist of the stops 33 firmly connected to a common plate 36. The support 300 comprises a crossbeam 301, which serves as a strut for the chains 31 and is attached to these chains by its ends, as well as a lower part 302 which is rotatably installed on the crossbeam and in this way can rotate about a horizontal axis »The Lower part 302 is provided with a fork-shaped piece 303, d _o h <. a piece that has a notch or recess 303a. A guide rod 305 is attached by its ends also connected to the two chains 31, namely concurrently to the cross member '301 and in front of this cross member with respect to the direction indicated by the arrow F direction of translation of the chains ₀ The guide rod 305 has, in its central region a portion with a smaller diameter 305a, in which the notch 303a is inserted. The plate 36 provided with the stops 33 has two pins or the like 37 in its lower region, which are provided with a notch 37 a for adaptation to the cross member 301. The plate 36 is in turn supported on the lower part 302 and is secured by means of a locking element which consists of a retractable pin 37

slidable finger 38 consists, attached to this lower part The Pinger 38 is exposed to the action of a return spring (not shown) and is firmly connected to a button or dglo 39 » This button enables the pinger to be withdrawn by sliding the plate under the action of the return spring, whereby this pinger with a projection or the like 302a_ of the lower part cooperated

The support 300, which caused by the cross member 301 and the guide rod is supported by two relatively far apart locations of the chains 31 305 this way secure hold of the attacks that do not tilt under the effect of the advance of the bottles kö "can ₀ On the other hand, in the case of the selector, the control of the rotation of the base 302 and consequently the stops themselves simplify the insertion of the fingers between the bottles and accelerate their withdrawal when they reach their end position, thereby synchronizing with the guide device is improved

If you have different types of stop sets, i.e. The guide device and the selection devices can use sets that include a different number of correspondingly spread stops be adapted to the number of elements used for the conveyor as well as to their mutual position.

The selection devices 40a, 40b, etc. are provided with supports for the stops, which are arranged according to a certain different division. The stopper rows 43 are installed course only on one of these selection devices, said device comprising a to the length of the matched to forming groups of bottles division has "Each selector is driven ν at a by GELsidiung (1) ν" V r- certain speed. A sufficient number of selection devices will be provided in order to satisfy all the selections required by the gripper heads and bottle types.

It should be noted that the dialers 40ji and 40b, the chains 41a, 41b are driven with the aid of the upstream chain wheels (as FIG. 1 shows) so that the upper Chain strand is held in place thanks to the thrust exerted by the bottles on the stops, while the anterior chain strand is loose «.

Furthermore, the adjustment of the arrangement of the stop rows of the guide device in relation to the gripper heads should be provided so that the exact provision of the bottles in relation to the gripping heads is secured, and this for every type of bottle or
