Description

Treating stones and forming recesses in layers of bricks In industry today, the stones are shipped from the place of manufacture - to the distributor and from the latter to the trusted trust in standard stone piles, which ten layers of stones contain, each tier consisting of eleven rows of stones, each row consisting of five Stones. These stacks are usually tied together by steel straps.

In addition, in many cases these stone piles are in the third Location of the floor recesses formed to accommodate the tines of a forklift truck to make handling easier during loading and unloading shipping or otherwise. Automatic and semi-automatic devices are designed to stack stones to form a standard stone pile. The present invention relates to a method and an apparatus for Handling stones to form a pile of stones of a predetermined size, a so-called standard brick stack, and in particular the invention relates on-the shaping of recesses in certain positions of the stones in front of the stack a pre-determined pile to form, with the recesses have the task of picking up the fork of a forklift for handling to facilitate the stack.

In addition, the present invention relates to handling of stones, the. from the point of supplying a kiln car to a fast one and efficient loading of predetermined groups of stones on a horizontal Floor conveyor used to form piles of stones to facilitate. It is an object of the present invention to provide a new method and apparatus supply, for the handling of stones or similar articles to predetermined Shape pile of stones.

Such a procedure is presented in more detail herein and a device contained for forming predetermined stacks of stones is used, which has a plurality of recesses for receiving the forks of Includes forklifts or similar devices.

Another object of the present invention is a new method and a device for forming recesses in St deposits in stone stacks are included. Also herein is an illustration of such a method and apparatus for forming the recesses, the method and that in connection with the stone unloader described in United States Patent Application Serial No. 153,577 can be used.

Another object of the present invention is a device for grasping from stones to recesses in certain layers of groups of stones, from many Consisting of layers to form. The exposition includes such an apparatus, the can be used in conjunction with a horizontal movable conveyor, to form recesses in certain layers of stones before they are removed from the conveyor be deposited for further stacking.

Another object of the present invention is a method and a device for loading predetermined groups of stones onto a horizontal one to facilitate moving conveyor. This includes provision such a method and device to allow a loading of the stones at relatively high Speed with a minimum of damage to the floors of the horizontal conveyor to enable. Next in this disclosure is such a method and apparatus included, which can be used in conjunction with stones used in usual or other arrangements are stacked on kiln cars and those of removed from the stacks using a conventional overhead separator (dehacking apparatus).

The above and other objects are accomplished through a process and achieves an apparatus in conjunction with a particular facility are summarized in a stone-making factory1 in which the stones after the Production leave the kiln on kiln cars, which flat platforms are carried for movement on rails; the stones are in groups stacked at a distance from each other on the kiln car. In this particular arrangement are two kiln cars that are located on one side of a horizontal floor conveyor are as described in the above-mentioned application, except that in the presently described arrangement the floors of the conveyor are every two tiers Stones, in which each layer consists of sixteen rows of stones, with each row consisting of four stones instead of two stones as in the one mentioned above Registration described.

In the first step, two groups of stones are replaced by a common one Overhead release device taken from each of the kiln cars and to reciprocating stations moved on opposite sides of the horizontal floor conveyor; every group consists of two layers of stones, each layer consists of sixteen rows, each row consists of four stones. The two groups taken from the one kiln car will on two sledges at one of the reciprocating stations and two groups of stones from the other kiln car are placed on two carriages at the other reciprocating station deposited below the path of the conveyor from the first reciprocating station is arranged. One of the sleds at each of the float stations is with a floor of the conveyor aligned so that the stones on this carriage through a pusher, which by a pneumatic engine or a pusher is driven, from the carriage directly to the with the floor conveyor aligned with the carriage. The sliding device located at the fixed station that is aligned with the floors of the conveyor is that switched for a certain size of gradual advancement of the floors is; a pusher link is connected to each reciprocating station. The others Carriages at each of the float stations are not with the other floors of the conveyor aligned so that it is necessary to move the carriage along the conveyor path move until the other carriages are aligned with the floors of the conveyor (and the sliding link). When the latter is achieved, the sliding links are again moves ore around the group of stones from the other sledges - on the aligned ones Press bottoms of the conveyor.

In the special arrangement, the conveyor and the sled follow timed to each other so that the two carriages are at the first reciprocating station Load every other floor of the conveyor that is on the second round trip.

Floating station leaves unloaded floors that are loaded by-the sled which should be below the first. Reciprocating station are located. The carriages can be mounted on fixed rails parallel to the path of the conveyor with the carriages having rollers that move along the rails. Everyone Matching motor mechanism can be used to move the carriage along the rails to move, e.g. pneumatic motors in connection with the slide on the back and floats.

In the particular device using a disconnect device, around the stones from the kiln car to the reciprocating stations by gripping members to transport, which individually grab the eleven rows of stones and which in a vertical Walk down towards the sled to get the stones on the sled after the grasping links release them, lay down the opposite sides each slide are formed by movable walls that expand after engagement move down through the grasping links to allow the grasping links to 'sidi move close enough to the sledge so that the stones are deposited on it can be.

Two layers of stones are on the floors of the conveyor in the previously described p Way loaded, the conveyor moves by switching forward to move the stones toward an unloading end of the conveyor. Before reaching the discharge end of the conveyor, certain floors reach the first station at which the formation of a recess begins with the aim of defining whole Remove rows of stones from the bottom layers of the stones to make recesses in the last shaped stone pile to form At this first station the conveyor stopped and a gripping head perpendicular to the entire upper layer of stones on the floors at the first station to grab the entire top layer and then remove it from the lower Able to lift and then move it down four stations from the conveyor, where the top layer is held over the conveyor path. The conveyor is then switched the remaining single layer of stones to the next, neighboring station to transport, ni what time a gripping head comes down and a certain number Remove rows of stones from the lower tier to make two recesses in the lower one Able to shape. The removed stones called "fork stones11" become then lifted up and moved to one side of the conveyor and onto a horizontal one Platform stored for later insertion in one of the floors of the conveyor, when the accumulated "fork stones" are enough to make a second whole layer of stones with each layer consisting of sixteen rows, with four stones in each Line.

The conveyor is then switched to the bottom row with the notches to the next neighboring station where a number of wooden pallets or plastic are placed over the lower layer to provide support for the same during further handling of the lower tier to bid when the last pile Bricks is formed after the pallets are attached to the lower layer of bricks are, the conveyor is switched again2 to the lower layer of stones to the next to move the neighboring station, which is exactly below the upper layer of stones, which, as described above, by a gripping head above the conveying path on the fourth Station is held.

The latter can then be operated down to the top layer To put stones on the layer containing the lower recess, then the conveyor can are switched again to the group stones with the recesses to the unloading station to move. At the latter station, the group of stones becomes transverse to the Conveyor unloads through an overhead operated pusher link which loads the stones a temporary horizontal support platform on one side of the Conveyor pushes as mentioned in the above-mentioned US application. the temporary support platform is then withdrawn to the straight two layers of stones on one unloaded from the conveyor with the recesses.

underlying stack of bricks (on an elevator) to stack the was previously unloaded from the conveyor. When a predetermined number of layers is on The elevator is softened, the stones on it become a swaying one Trolley conveyed, which then moves to the neighboring steel belt station, then the stones are removed from the reciprocating cart at the steel belt station unloaded, the tape is wrapped around the stones, and the stones become an exit moved for shipping or any other purpose.

The method and device that enables the unloading of the stones from affecting the conveyor and moving it to the steel belt station is an issue of US application Ser. No. 153,577 and forms the core part of the invention contained in this Registration is currently claimed. The special Device, for removing the topmost layer of stones and for shaping the recesses in the Ground layer stones is described in detail below.

Further advantages and possible applications of the invention result from the accompanying illustration of an exemplary embodiment and from the following Description.

Reference should now be made in detail to the drawings, initially to FIG. 1 will be entered where a stack or package is generally ten of stacked bricks 12, which is a standard commercial stone pact that is used for transportation the Stones from manufacture to retail or from retail to locations of the Consumption is used, among other things.

Stack 10 contains ten layers of bricks, each layer being excluded the third layer from the bottom contains eleven rows of five stones each, although it does not is shown, stack 10 is secured by steel straps so that it is as a unit during the transport can be handled. In the third layer from the floor there are two adjacent rows of bricks removed, in two places able to make a few recesses 14 to accommodate the forks of the forklift or similar device to make it possible to conveniently raise or lower the entire stack and transport it with a forklift. By training the Recesses 14 can be seen that the third, fourth, eighth and ninth rows of stones are away from the third layer.

To provide support for the third layer during the pre-stacking provisionally to provide for the formation of the final stone stack is in addition a plate 16 attached to a support between the third layer of stones to ensure. Although not shown, a board such as 16 can be about as well The second layer stones are arranged to provide a support to the third layer to depict which the recesses will contain when stacked on the second layer will. Board 16 also protects the stone surfaces from damage by the forks of the forklift. Board 16 can be made from thin sheets of wood or plastic or anything other suitable tabular or thin material can be made. Instead of one single plate can additionally and likewise not shown one Variety of panels are used by placing them in a side-by-side relationship between the third and fourth layers and between the second and third layers. It is understandable that the stone pile itself is common and not part of the present one Invention forms. The method and apparatus of the present invention will be however, used to manipulate stones, to form piles 10 and around recesses 14 to form stones in certain layers, which can be found in the stack of stones 10 are located.

In FIG. 1 a, a method for making recesses in layers is graphically shown of stones in a special application, with two layers of stones lengthways be moved along a horizontal path, such as Z, B. by a conveyor 20; 19a represents two layers of stones as they were originally loaded onto the conveyor 20. Conveyor 20 is preferably a floor conveyor as shown in FIGS is and will be discussed in more detail below in connection with the device of the present invention. Back to Figure Ia; the two layers of stones which form the group 19a are moved to the right, as can be seen in Figure 1a, until the group reaches station C, which is between the ends of the conveyor, at what time the conveyor will stop moving. The upper layer of the stones is then raised and from the lower layer of the stones to station c. separated and then the upper 0 1 '11 1 layer is moved in the direction of the conveying movement to station F, welE located in front of the discharge end of the conveyor 20; the movements the upper layers of stones are shown with arrows in FIG. 1a. At station F. the top layer of stones is held above the conveyor as shown in Figure 1a is.

In Figure 1b, the conveyor is switched again to the lower layer Move stones to the next neighboring station, labeled D, where two Pair of adjacent rows of stones removed from it, called the two recesses V, to form stones in the lower layer. As described below, the removed stones TB, referred to as fork stones, removed upwards and for that the following insertion is stored on the conveyor 20. In Figure 1c, the conveyor 20 operated again to move the lower layer of stones to the next adjacent static E, to move where the conveyor is stopped again and relatively solid boards, like board 16, stones are placed over the lower layer, which contains the recesses, placed.

In Figure 1d the conveyor is operated again to the lower recess containing layer stones with the board 16 on it to the next neighboring station F to move where the conveyor is stopped again. The upper layer, which was held above station F, is then lowered and comes to the lower one Lay stones back, whereupon the conveyor 20 is moved again to the two layers Stones with the recesses in the lower layer of station F to move to the unloading station of the sponsor. After unloading from the conveyor, the two lower tiers become Bricks stacked up on a hoist with the cutouts in the lower tier ten layers are reached, whereupon the stack with the ten layers to a steel belt station is promoted, according to the method and apparatus disclosed in the US application Ser. No. P3,577 is described.

It is noted that Figure 1a to Id shows only one group of stones, in which the lower layer contains recesses. The other group consisting of i9a stones of two layers that are conveyed to positions on the conveyor 20 at the same time precede and follow the group of stones that contain the recesses, which are shown in Figure 1a to d, for the sake of clarity in Figure 1a to 1d omitted. These other stones are in Figures 18a through 18d and others Figures in connection with the device of the invention included, which in larger Details will be described below. It is also understandable that if the method and apparatus of the present invention is used to produce a To form standard stone stacks, the ten layers of stones with recesses in the third Position from the ground, every fifth group (each group consisting of two layers) of stones carried on the conveyor is treated in the same way as it is in dn Figures la to 1d is shown to form recesses in the lower layer.

Referring to Figure 2, there is shown an apparatus employing the invention and that can be used to determine the procedure which. above in connection with Figures 1a to 1d has been described to perform. In the special arrangement, shown in Figure 2, which is currently in a normal operation in a brick factory is used, the stones are stacked in groups consisting of many layers, 19, with gaps on a kiln car 18, which is on rails in. an oven (not shown) for drying and firing and out of the oven for subsequent Handle for stacking is moved, like the standard most-in-stack 10 O in Figure 1 shows. After leaving the furnace, the stones are placed on the kiln car 18 to a position on one side of the floor conveyor generally designated 20, transported, which is along a horizontal path. emotional. By usual The stones are taken from the groups 19 onto the kiln car 18 and to loading or to-and-fro stations designated A and B on the other Side of the conveyor 20 forwarded as shown in Figure 2 for loading onto the floors of the conveyor is shown.

According to the invention, the stones are in two layers loaded the conveyor; each layer contains eleven rows of stones of four stones each; the two groups of layers of stones on the conveyor are designated 19a in Figure 2 After the stones in group 19a are loaded onto the conveyor, the conveyor moves Conveyor gradually around the stones 19a to an unloading station on the right side of the conveyor (see Figure .2).

At stations C, D, E and F in front of the unloading station, certain Groups of stones conveyed by the device 90 and 120 are further processed to create recesses Form V in the-lowest tier in accordance with the procedure described above. The next following station F is the unloading station, where a sliding member 22a, which mounted on endless chains 22 is, works, 'around the groups stones 19a to push the side of the conveyor 20, on a temporary horizontal one Support platform, labeled 24, which lies on top of the elevator (not shown), on which previously the unloaded stones were stacked X den. Platform 24 is in a horizontal plane under the discharged stones 19a moved to the same on the underlying stack of stones on the elevator, which then takes a step is lowered to accommodate the next group of stones, which are from the conveyor 20 are unloaded on the platform 24 to be deposited. If a predetermined number If layers have arrived on the elevator, the stack becomes one from the elevator reciprocating carriage generally referred to as 26, which then moves after is moved to the right, as shown in Figure 2, to station 26, where a pusher member 29 the stack in a binding device generally designated 30, pushes where a binding head 32 provides the stack with steel bands. The stack will then go through a slide member 36 is pressed to a further process station 34. The procedure and the device concerned with the unloading (22, 22a, 24, 26) of the stones, the stacking into a finished stack and conveying to the binding station, etc., are in the U.S. application Ser. No. 153, 577 and do not form part of the invention, which is claimed in the present application. To get a more detailed description of the unloading and binding process should refer to the US application will. Close in the particular arrangement shown the floors of the conveyor 20 has a flat bottom wall 40 and upstanding opposing ones End walls 42 of sufficient height to accommodate at least two layers of stones, such as it is shown in FIG. The floors 40, 42 can be made of any suitable material, E.g. steel, and are on endless drive links, like the chains 44 secured, which are pulled around end pulleys 46 in the usual way, as shown in FIG. Any suitable steel structure, the horizontal one Channels 48 supported by vertical pillars 49 can be used to carry the floors, the endless drive chains and the pulleys.

Similarly, any suitable motor can be used to power the conveyor to drive in the usual way. In those cases where more than two layers Stones are conveyed through the conveyor, the side walls 42 of the floors executed from greater height. The same thing will be said about the distances between applied to the side walls 42 in each of the floors, changing the spacing depending on the number of rows of stones to be conveyed.

For maximum operating conditions it is preferred that the neighboring Floors are attached as close to each other as possible, as shown in Figures 2 and 3 is shown. The mode of operation of the conveyor is such that it is an intermittent Advancing and stopping allow certain work steps with the stones allow the stones to be loaded onto the conveyor at the reciprocating stations-A and B, the subsequent forming of the recesses in certain groups of the stones at stations C, D, E and F, as will be described in more detail below. Additionally is preferred to have one Pressure control button on the platform P is placed adjacent to stations C, D, E and F for the operator to allow the conveyor 20 to advance during the recess forming process and to stop.

In Figure 2 in conjunction with Figure 7b, 8 and 9 are four groups Bricks 19a taken from the groups 19 on a kiln car 18 and in two layers of sixteen over four stones at two reciprocating stations A and B, shown in Figure 2, drained. Two groups 19a are at the reciprocating station A is unloaded and two other groups are unloaded at shuttle station B, As shown in Figure 2, the outward and backward movement station A is identical to the outward and float station B except that the latter is below the conveyor path of the reciprocating station A is arranged. The float station A includes two carriages, each consisting of a base plate or platform 52 which is generally rectangular in shape and a matching one Material such as

Steel plates are made and of sufficient size and strength to to accommodate two layers of stones, each layer having sixteen rows of four Contains stones.

The carriage platform 52 is attached to side members and the Side links form a rectangular frame; the side links are steel box links 56 and the end links are shown as steel box links 54 suitable, to be connected to the side members 56 by bolts or welding. the Carriages are movable along the conveyor on a track made up of rails 50 exists parallel to the conveying path; any suitable roll mechanism, e.g. 58, can be attached to the ends of the links 54 of the carriage to slide over the rails 50 to roll, the sleds are at each station with one another with a gap connected to be operated simultaneously as a unit. Operation of the Carriage along the rails is preferably achieved by a suitable motor a pneumatic or hydraulic motor 59 having an operating rod 59a, which is connected to the two carriages at the reciprocating station to they at the same time as a unit along the rail in aligned position with the Moving floors. Alternatively, the motor 59 can be connected to one of the carriages because the sledges are spaced apart and attached to each other and the movement of one sled is transferred to the other so that both are together moving as a unit in a special arrangement where the stones are in two, Groups 19a from group 19 onto kiln car 18 by conventional Sberkopf separating devices be moved, which two groups take stones 19a, -and they in a fixed keep lateral spacing relationship, it is necessary that the distance between the platforms 52 the sled is the same as the distance between the groups of the stones 19a when they are held by the separator so that it is the Separation device is possible, both groups of stones 19a simultaneously on the two Platforms 52 to deposit the carriage. Because this distance between the platforms 52 the carriage is not the same as the distance between the floors of the conveyor 20, it is necessary to move the carriages to alternate the platforms 52 to place the carriages in alignment with the floors of the conveyor 20.

During operation and only with regard to the reciprocating station A, assuming the two carriage platforms 52 are empty, become two Groups of stones 19a removed from kiln car 18 and at the same time at station A successively set down on the slide platforms 52. At this point it is one of the carriage platforms 52 aligned with one of the bonds of the conveyor 20, and in this way enables the croup of stones 19a from the sledge to the ground the conveyor to be pushed over 2G; Figure 2 shows this alignment and a group of stones 19a just moving from the stacking platform 52 onto the floor conveyor pushed over The pushing over of the stones 19a from the sled platform 52 onto the conveyor floors can be done in any convenient way; one of the procedures is by a sliding member 82 in the form of a plate in the horizontal plane, which is operated by a pneumatic or hydraulic motor 80 so that -the Group of stones 19a is pushed over the carriage platform 52, directly onto the Bottom of the conveyor 20. After the first group of stones 19a was slid off the sled platform 52 onto the leveled floor it is then necessary to operate the carriage by the motor 59 to the other Bring the sled platform into alignment with the floor to avoid sliding over the stones 19a from the other carriage platform towards the aligned floor In the particular arrangement shown will allow 'after the first carriage is unloaded at station 4, as shown in Figure 2, the conveyor is switched twice and two steps forward moves 9 the second following floor 2 as 40a in figure 2, with the rail member 82 aligned. The sleds are then in Motion set to move the other carriage platform 52 into place, which the group of stones 19a thereon in alignment with the slide member 82 and the Contains bottom 40a, whereupon the motor 80 can be actuated to the other group Move stones 19a onto the floor 40a. In this way it can be seen that in In the particular arrangement shown, the groups of stones 19a at the shuttle station h can be loaded into any other conveyor floor. The floors that are not at station A are loaded, are loaded at station B, by a similar second carriage return and float system, which need not be described as it is identical to the first at station A.

From Figures 7, 8 and 9 it can be seen that each of the carriages are platforms 52 has upstanding side walls, shown as inwardly L-shaped Angle members 60 to the Record group stones 19a. If the Bricks are conveyed from the kiln car 18 onto the carriages by means of the overhead separating device, Indicated generally at 74 in Figures 7 and 8, it is preferred that the side walls 60 are vertically movable around the stone gripping fingers 76 of the separating device 74 to enable the groups of stones 19a to be placed precisely on the carriage platform 52, as shown in FIG. In order to achieve the mobility of the side walls 60, the latter are provided with depending rods 62, generally on the opposite ends where they are slidably mounted in vertical guide sleeves 64 are 'generally at' the four corners of platform 52 for hanging therefrom. The shorter ends of the rods 62 on either side of the platform 52 are one below the other connected by cross members 70, as shown in Figure 9, and a suitable tensioning device, such as tension springs 69 are between the frame members 56 and the lower cross members 72 connected to bias wall 60 in the up or raised position, as shown in FIGS. 8 and 9. During operation when the group has stones 19a is deposited on the carriage platform 52, as shown in Figure 7, grab the stone gripping fingers 76 of the overhead separator 74 the tops of the side panels 60 to do the same towards the platform 52 against the bias of the springs 69 to enable the stones 19a, right on the surface of the platform 52 to be ordered afterwards when the fingers 76 go apart, to let go of the stones 19a and move the severing device 74 back up away from the stones and platform 52, as shown in Figure 8, the springs 69 come into operation to bring the walls 60 to their normal raised position above the Platform 52 to bring back the stones 19a for onward transport on the floors of the sponsor.

When the group of stones 19a, in the recess, in the lowest Position is to be formed, station C reached, (see Figures 2, 3 and 18a to 18d), the recess forming process begins. At this point the conveyor 20 is stopped and an overhead gripping head, commonly referred to as 90, comes down to the to grab the entire upper layer of the stones and lift them up from the lower layer and then the top layer via the conveyor path four stations to station F to hold the top tier above the conveyor. The latter is in figure 6, the upper layer being designated as TL and also in FIG. 18a, which represents the movement of the upper layer over four stations to station F. The conveyor 20 is then operated again9 to move the lower layer of stones LL to the next adjacent station D- as shown in Figure 18b, AT what time the advancement of the conveyor is stopped and a gripping head generally at 120 marked, comes down to the third, fourth, and eighth, ninth row of stones in the lower position to grab LL and pick them up and them to move to one side of the conveyor where they are on a horizontal bearing plate 170, which will be described in detail below. Sponsor 20 is switched again to advance the lower layer LL to the next adjacent one Station E, where a board 16 is placed on the lower layer LL, as shown in FIG. 18c is shown to provide support for 'the same. Sponsor 20 will be back switched to advance the lower tier LL to station F whereupon feeder 20 is stopped and the rock grab head 90 comes down and the top layer CL Stones on the lower layer LL, as shown in Figure 18d, and then returns to its starting position at station C. Sponsor 20 then hosts actuated to move the group of stones holding the recesses to the unloading station, where a pusher member 22a takes the same from the conveyor 20 in the manner described above unloads the fork stones removed from the lower layer LL'S stones at station D. are, on a horizontal platform 170S as in Figure 29auS of the one Side (of it conveyor 20 stored. After the platform 17Q picked up the fork stones it is moved over the conveyor 20 to the operator who is on the Platform P stands to allow fork stones TB to be removed from platform 170 and place them on the loading platform 199 which is aligned with the floors of the conveyor 20 aligned is. The operator standing on platform P, which monitors the switching movement of the conveyor 20, calls for one at intervals empty bottom, so that when two layers of eleven over four stones are accumulated have on the loading platform 199, they on the requested empty floor through a Sliding member in the form of a vertical plate 200 which is driven by a pneumatic Cylinder or motor 202 is actuated under the supervision of the operator who on platform P can be transferred. The movement of the storage platform 170 above the conveyor result as well as gripping the top layer TL and the bottom layer Position LL of the stones and the shaping of the recess as described above is shown below described. The device incorporating the latter features has been shown in FIG 2 removed for clarity. Although not shown, another device can used to lift the -accumulated fork stones directly from the platform 170 to be transported to the conveyor floor.

Figures 4 and 6 show the gripping head 90 used to handle the entire upper layer TL stones before forming the recesses in the lower layer LL grab, which is operated vertically to raise and lower the gripped stones, by using a suitable motor, such as a pneumatic motor 98, which has an actuating rod 99 which is connected to the gripping head 90 is.

The horizontal movement of the rock gripping head 90 to their, Moving between stations C and F as described above is done by a Reached slide, generally designated 91, in which a pneumatic motor 98 is suitably attached to the slide along a fixed horizontal Rail defined by rail 93, parallel and across the conveyor line between Station C and F to be moved as shown in FIG. The rails 97 are secured with horizontal beams 94 which are at their opposite ends supported by vertical columns 95. Carriage 91 is with suitable rollers 92 on the opposite sides thereof, which are received by the Schieen93 will. In addition, there is another one between the carriage 91 and the rails 93 A pair of rollers 92a are provided for further guidance and to facilitate movement of the slide (see Figure 4).

FIGS. 12 and 14 show a stone gripping head 90 which is made from an orund plate 115 that is in the shape of a rectangular steel plate or other component may have an upstanding, generally rectangular frame which is formed by angle iron, e.g. 116 and 117 suitably attached, such as by welding or riveting to the base plate 115. On opposite On sides of the base plate 115 are rotatably a plurality of L-shaped stone gripping members attached, generally designated 100; there are eleven stone claws, on each side of the Base plate 115 to enable the eleven Rows of stones to pick up. On occasions where a greater or lesser number When rows of stones are handled, the number of stone claws will become 100 is increased or decreased. The stone gripping members 100 are on horizontal shafts 102 mounted for rotatable movement; the shafts 102 are adapted to be parallel to the base plate 115 fixed by stops 103, which on opposite Ends of the base plate 115 are attached. The standing grips 100 are at intervals disposed along shafts 102 so that each rock gripping member 700 is capable of access a single stone 12 as shown in Figure 14 '. The distance The gripping members 100 are held by suitable spacers 110 on the shaft 102 are attached via the corner parts of the gripping members 100, reached to the gripping members 100 in the appropriate position along the shaft 102 to hold.

Actuation of the stone gripping members 100 may be any suitable Way to be achieved; one of the methods is shown in Figures 12, 13 and 14, which uses what might be referred to as air bags 106 and 108 in the form of elongated inflatable and deflatable flexible guides. The stone claws 100 are formed from depending lower parts 100a which are suitable for the Gripping stones as shown in Figures 12 and 14 and upper parts 100b, which extend at an angle of approximately 900 relative to the lower parts 100a, around the grasping links between an outer stone release position, shown in Figure 13, and an inner stone gripping position shown in Figure 12, to operate. The upper parts 100b of the stone claw members 100 extend further inside of the shafts 102 to be between an overlying air bag 108 and an underlying airbag 106 to be located. The upper air bag 108 extends under an angle iron 118 attached to the frame member 116, such as it is shown in Figures 12, 13 and 14 and is suitable for its opposite Ends securely attached to the frame by means of fittings. The lower air sac 106 is similarly attached, relative to the base plate 115, to under the upper parts 100b of the stone claw members 100 to lie.

The ends of the air bags 106 and 108 are provided with an air source and other air regulators and valves (not shown), so that they can be alternately inflated and deflated to the stone claws 100a to rotate in stone release or stone engagement positions.

It can be seen that when the upper air bag 108 is inflated as shown in FIG Figure 13, engages the upper portions 100b of the gripping members 100, to move the same downward by rotation about the shaft 102, what the lower Stone gripping link parts 100a are moved counterclockwise by the stones as shown in Figure 13 to release the stones. When the top Air bag 108 deflated is-t and the lower air bag inflated is, as shown in Figure 12, the result is an opposite movement the stone claw members, which causes the lower stone claw parts to move Turn 100a inwards in order to reduce the damage to the stones and to achieve an accurate To be sure of gripping movement are the inner surfaces of the link parts 100a with flexible covers, such as rubber or plastic pads 100c of a suitable type Provide flexibility and strength.

The extension of the operating rods 142 is controlled by the motor 140 causes that. moves the fork stone grab head 120 to one side of the conveyor, such as it is shown in dashed lines in Figure 4 while retracting the Actuating rod 142 'causes the gripping head 120 to move over the conveyor into the Frc; ition moves that with full lines shown in FIG is.

As described above, the clevis gripping head 120 is also in one vertical direction-movable back and forth from the conveyor 20 by the movement carriage 150 along rails 156 attached to column 157; the.

Frame 137 is attached to carriage 150 and extends in generally at right angles to this. The, carriage 150 is provided with rollers 154, which are raised by the rails 156, as well as the additional rollers 152 movable by one of the flanges from the rails 156, as shown in FIG Figures 4 and 5 is shown. The vertically movable carriage 150 is slow Rail 156 operated by any suitable motor, preferably pneumatic Engine (not shown).

After the fork block TB has been picked up by the gripper head 120, the latter is moved up and then to one side of the conveyor moved down to store the fork stone on the bearing plate 170, which is in a horizontal plane is attached to the movement * of the conveyor as indicated by dashed lines Lines shown in Figure 4 is and an advanced position which is the conveyor 40 as shown by solid lines in FIG. The withdrawn Position of the bearing plate 179 is used to hold the fork stones TB from the gripping head 120 up- * between the retracted position on one side gain weight, while the extended position of platform 170 is used to lift the fork stones to be placed sufficiently close to the platform P (see Figure 2) to allow the operating personnel to that stands on the platform P, to enable the fork stones TB to be removed and them on the loading platform 199 for re-loading onto the floor 40 of the conveyor 20 as described above. The horizontal movement of platform 170 between the extended and retracted positions is adjusted by rollers 174 the opposite sides of it fastened in rails which are fastened by a Frame 172 are formed and a motor, preferably a pneumatic motor 176, which has an operating rod 178 which with the platform 170 through a band 179 is connected. The frame 172 is a steel structure, suitable attached to and between the pillars 157 in a horizontal plane. Engine 176 is attached to the underside of the frame 172 as shown in FIG The removal of the fork stones TB in the process of forming the recess is still to be carried out To summarize once: when the lower layer of the stones LL reaches station D. (see Figures 2 and 18b) the advancement of the conveyor 20 is stopped and accordingly Figure 17A, the pneumatic motor 140 actuates to drive the movable frame 130 of the Gripper head 120 outwardly over conveyor 20, as shown in Figure 17A is shown. The bearing plate 170 is withdrawn, the carriage 140 then becomes to the lower frame 130 and the gripping head 120 moved down to the stone gripping members 124 for gripping the fork stones TB in position, as shown in Figure 17B shown is, after inflating and deflating the air bags 126, 128 as described above became. The carriage 150 is then moved upward to remove the fork stones TB from the lower layer LL of the stones shown in Figure 17C. The ones left behind Stones in the lower tier left on the floor 40 of the conveyor 20 are not shown in Figure 17C to avoid confusion. The frame 130 of the gripping head 120 is then moved back to one side of the conveyor after the motor 140 has been actuated, whereupon the carriage 150 moves downwards, to place the fork stones TB on the platform 170 as shown in Figure 17D is, wherein the gripping members 124 are operated to the stones on the platform 170 letting go. The carriage 150 is then raised back to its original position, as shown in Figure 17A after the platform 170 advances through the the motor 176 is actuated to bring the fork stones TB over the conveyor path, (see FIG. 17E) in order to allow the operating personnel standing at the platform P. to allow the fork stones to be removed from the platform 170 and placed on the To set the loading platform 199, as shown in FIG.

The fork stones are removed from the lower stone layer LL, the conveyor 20 is actuated again to move the lower layer with the recesses V to the station E as shown in Figure 18C, where operator pointing to the platform P stands, puts a board 16 over the lower layer LL.

When the last operation is done, the operator operates on platform P again the conveyor to the lower layer with the recesses and Then move the board to station F, whereupon the conveyor stopped again will. The motor 98 is then operated to lower the gripping head 90 to place the upper layer TL on the lower layer LL again, as shown in FIG 18D is shown; after the top layer is placed on top of the bottom layer the gripping members 100 of the gripping head 90 rotated outwards to the upper layer of stones let go.

The gripping head 90 is then stationed in its original position C as shown in FIG. The operating staff on the platform P can then move the conveyor around the group of stones 19A with the recesses move the lower tier to the unloading station for the conveyor to pass through To unload slide members 22A in the manner described above.

Although the recess-forming process described above requires that the upper layer of the group of stones, the lower layer of which contains recesses over the lower tier must be raised to provide access to remove the fork stones to allow from the lower layer, the recesses can also be on another Be shaped in ways that avoid the need for the gripping head 90, which used is used to lift the top layer of stones. This is done by using the Layer that contains the recesses'ais a single layer, i.e., without any upper layer. This happens, for example, when a standard brick stack with ten layers is formed by conveying the stones in four successive floors in two layers and then the following floor in a layer which is the one with the recesses is, and the next floor in one layer. The fork stone removal head 120 can then used to remove the fork stones from each layer of the floor remove as described above. The location with the cutouts in it will then unloaded from the conveyor 20 as a single layer after the recesses were molded in it. Another alternative when forming a standard pile of stones With ten layers of stones, the stones is in three successive floors in two To promote layers per floor, with the fourth floor containing three layers and the fifth Bottom contains a single layer that contains the recesses.

This in turn avoids the need to use a gripping head 90 and the associated device to place the upper layer of stones, as described above, In Figures 15 and 16, a modified stone gripping head is shown, i. a modification of the rock gripping head 120 shown in Figure 10 and above was described .. The modified gripping head, generally designated 220, consists of a main frame in the form of a steel beam 222, which is attached to the opposite Sides two pairs of parallel right-angled tubes 224 has 0 The right angle tubes 224 are with each other as well as with the main frame 222 connected by threaded bolts 2309 which are taken up by SHtahlpipes 226, the across the top surface of the main frame 222 and frame tubes 224 are attached. The tubes 226 are solid, relative to and relative to each other attached to the frame 220 in a suitable position by lock nuts 232, which are of the bolts 230 on the opposite sides of the frame are taken out For example, the tubes 226 are internally threaded to receive the bolts 230.

Each pneumatic motor 250 is. to sliding Movement to the Top of the connected tubular frame 224 by an upstanding bracket 256 attached, with 'a cylinder, which is in a parallel plane above the tubular frame 224 lies. One end of the pneumatic cylinder is at 260 with a gripping member 240 connected via an arm 241a which is fixed to the link 240 at right angles thereto is attached as shown in FIG.

The other Greifgiied is with a moving back and forth Piston rod 252 of an air cylinder 250 through an arm '251 and a link at 253 as shown in FIG. Any suitable piston arrangement can be provided in the air cylinder 250 so that after filling or emptying with air in or out of the cylinder 250, the limbs 240 straight in or out move the engagement with the fork stones TB: the movement of the links 240 will inevitably guided in a sliding manner in the tubes 224 by the rods 242. The shown Arrangement wherein the pneumatic motor 250 has a single inner piston 250a owns, tr / a piston rod 252 is attached, if air on the left Side of the head 250a, as can be seen in Figure 15, is effected, that the piston moves together with the rod 252 to the right, whereby the left gripping member 240 is brought into engagement with the stone, at which time ~ further air is introduced into the left side of the piston 250a, which causes that the inner cylinder 250 moves to the left as shown in dashed lines is shown in Figure 15, with the right side of the fork stones TB engages. Side and vertical movement of the pneumatic motor 250 is prevented by upstanding brackets 256 connected to it, the are forked over the cylinder 250. The brackets 256 shown in FIG are omitted from Figure 16 for clarity.

The vertical movement of the inner clevis head 220 will achieved in the same way as described above in connection with the Gripping head 120, by means of a vertical rod, suitably attached to the frame 222 attached above stops 270 as shown in Figure 16; the vertical ' Rod is mounted in a movable frame such as the one described above 130. If so desired, and although not shown, a second piston assembly may be used be provided in each pneumatic motor cylinder 250 with two operating rods, which are connected to the piston or to the gripping members 240. In this modification the pneumatic motor cylinders 250 are attached to the frame against all movements, and movement of the gripping members 240 is provided solely by their connected piston rods achieved.
