As this takes place, a free space sufficient for complete release of the tyre (25) is available between the support plate (8) and arched plate (12) with rounded edges.
- the tyre (25) completely expands across the entire inner perimeter of the tyre (24) under action of internal forces. Packaging of the tyre (25) is completed (Fig. 14). Then, a reverse process takes place during which a finished package comprising tyres (24-25) is released. After this, all mechanisms of the device return to the initial position.
- the mechanism (1 1 ) for feeding and packaging the compressed smaller diameter tyre begins an upward motion. Simultaneously, the following mechanisms automatically return to initial position thereof: the mechanism (6) changing the trajectory of motion of the compressed smaller diameter tyre (the motion of the mechanism's stop reverses) and flat compressing members (10) (expand).
- the sensor (not shown) supplies a signal to operate a downward motion of the movable platform table (3). Therefore, the package comprising tyres (24-25) arranged on the table (3) becomes accessible to be unloaded out of the device. After unloading a finished package, the device is ready for further use. If an additional tyre needs to be packaged in the interior space of the package (24-25), the above process should be repeated for packaging a tyre of even smaller diameter.

Description
METHOD AND DEVICE FOR PACKAGING TYRES
The invention is related to the field of transportation of autotyres and may be used to safe transportation expenses by forming packages comprising at least two (three of more under specific conditions) tyres, thereby increasing the quantity of loading units of tyres per unit loading area during transportation thereof. Patent No. EP 0723914 discloses a device and method for insertion of tyres. The method and device disclosed in the above patent, however, not always provide tyres packaging.
The prior art device have the following disadvantages described below.
The compression method provided in the patent causes rather large residual deformations of crimp rings of an inserted autotyre and may damage it. An assembled wheel is not adequately hermetic and it is not possible to further use it without additionally placing an interior tube into it.
The mobile operation thereof is not possible due to large dimensions, mass and complexity of the device and also substantial energy input.
The object of the invention is to maintain the quality of the packaged tyres, reduce energy input associated with the packaging process, facilitate and increase convenience in operating the unit.
The above objects are to be addressed using the following solutions: -The tyres are packaged in such a way that smaller diameter tyres are compressed predominantly in one plane, perpendicular to the diameter thereof. The compressed tyre is placed at an angle to the plane of a large diameter tyre and the smaller diameter tyre is controllably inserted into an interior space of the larger diameter tyres simultaneously changing the direction of motion.
-The smaller diameter tyre is compressed by using flat compressing members. As a result, an tyre takes the form of an oval or the form resembling a figure "8". In this case, residual deformations are extremely low or absent at all resulting in a failure- free operation of tyres in the future.
- Sliding surfaces, rotary rollers and rotating elastic bands comprised in the flat compressing members contribute to the reduced friction force occurring between
surfaces of flat compressing members and a compressed tyre. This facilitates the motion of the smaller diameter tyre into an interior space of the larger diameter tyre.
- A mechanism changing a trajectory of motion of the smaller diameter tyre and eliminating excessive loads on the tyre during packaging is used to avoid deformations associated with packaging of smaller diameter tyres in the interior space of the large diameter tyres .
- An arched plate with rounded edges of a mechanism for feeding and packaging the smaller diameter tyre prevents the tyre parts from entering into the space between the arched plate and flat compressing members due to the arced shape thereof, thereby eliminating tyre excessive deformation.
- The arched plate with rounded edges fixed in some cases at a specific acute angle (or this angle will change automatically) facilitates the release of the tyre at the final packaging stage, thereby also eliminating excessive tyre deformation.
- Relatively low weight and overall dimensions of the device (if wheels are available) make it possible to freely move it, thereby allowing for mobile operation thereof.
- A minimal number of cylinders actuating the assemblies of the device allow high air (hydraulic fluid) consumption to be reduced, thereby eliminating high energy consumption.
Multiple experiments have been conducted to determine the arrangement of the tyre surfaces at an angle in the process of packaging and the method used for controllably feeding and controllably changing the trajectory of the smaller diameter tyre, as well as the construction and configuration of the mechanism changing the trajectory of the smaller diameter tyre, compression planes and the mechanism for feeding and packaging the smaller diameter tyre.
The tyre to be packaged may be packaged without damage by using exclusively the means of controllable feed and change in the trajectory of motion of the smaller diameter tyre and also by applying the method of compressing the smaller diameter tyre with flat members.

The device for packaging smaller diameter tyres into the interior space of the larger diameter tyres comprises the following components: a movable platform; a mechanism for stretching a larger diameter tyre; a mechanism changing the trajectory of motion of a smaller diameter tyre; a mechanism for compressing a smaller diameter tyre; and a mechanism for feeding and packaging the compressed smaller diameter tyre.
A base (1) of a movable platform is a stationary part and has a frame construction serving as a foundation for the movable platform. Connecting struts of the entire device are secured thereto.
The movable platform is intended for placing a larger diameter tyre thereon and stretching it. It comprises the base (1 ), a lifting device (2) and a table (3).
The lifting device (2) of the movable platform is a movable part and it comprises two movable frames connected therebetween with a longitudinal axle in
the middle. It is intended to actuate the table of the movable platform (3). The lifting device (2) of the movable platform is provided with attachment points designed to secure it to the table and movable platform base.
The movable platform table (3) is intended for arranging a large diameter tyre thereupon. It has a frame construction mounting two expandable grips (4), a mechanism (6) changing the trajectory of motion of the smaller diameter tyre and a support plate (8). Attachment points of pneumatic (hydraulic) cylinders (17) actuating expandable grips (4) are disposed on the sides of the table frame. In this case, the expandable grips (4) are arranged in such a way that holding plates are directed upward.
The mechanism for stretching a larger diameter tyre is intended to stretch and hold the larger diameter tyre in the process of packaging of the smaller diameter tyres in the interior space thereof. It comprises the movable platform> expandable grips (4) and a middle part (9).
The base (1 ) and lifting device (2) of the movable platform are provided with attachment points for pneumatic (hydraulic) cylinders (16) actuating the movable platform table (3).
The expandable grips (4) comprise movable members and are intended for gripping and holding the large diameter tyre while it is being stretched. The grips are configured as a rectangular frame provided with a semicircular segment with a holding plate. The grip frame construction is provided with attachment points which are used to mount the grips in the frame of the movable platform table (3) and the frame of the middle part (9), and components for connecting with pneumatic (hydraulic) cylinders (17) actuating the grips (4) are also provided. A synchronizer (5) provides a synchronous motion of the expandable grips disposed in the middle part (9). It is required to avoid contact between the grips (4) and plate (12) in the process of packaging. Unavailability of the synchronizer may lead to blocking of the feeding and packaging device (1 1 ).
The middle part (9) is a stationary component and it serves for holding the larger diameter tyre while it is being stretched by the movable platform of the stretching mechanism. It is also an intermediate part of the entire device construction to which connecting struts are secured. The middle part (9) has a frame construction to mount two expandable grips (4) within it. The attachment points of pneumatic (hydraulic) cylinder (17) actuating the expandable grips (4) are disposed on the sides
of the middle part frame. In this case, the expandable grips (4) are arranged in a position in which holding plates are directed upward. A guard plate (22) is disposed on the rear part of the frame and center-oriented. A safety panel (21 ) is also disposed in the middle in the rear space between the middle and upper parts of the device. These means are intended to prevent inadvertent deviation of the compressed tyre (25) from the trajectory which is required to be followed in the process of packaging.
The mechanism (6) changing the trajectory of motion of the compressed smaller diameter tyres erves to change over this tyre to the plane of the larger diameter tyre.
It comprises the guides along which a movable stop (7) moves, a support plate (8) and a protective housing (23). The mechanism (6) changing the trajectory of motion of the compressed smaller diameter tyre is disposed in the middle of the frame of the movable platform table (3) and is covered with the support plate (8) from the top. In this case, an upper part of the stop (7) is located at a specific distance over the support plate (8). The mechanism changing the trajectory of motion of the tyre is provided with an attachment point of a pneumatic (hydraulic) cylinder (19) actuating the platform with the stop (7). The protective housing (23) is a plate bent to form a U-shaped profile and serves to protect the pneumatic (hydraulic) cylinder (19) from possible damage and dirt ingress. The mechanism (6) changing the trajectory motion of the compressed smaller diameter tyre may be also provided with a guiding plate instead of a stop.
The support plate (8) serves as a sliding surface for the smaller diameter tyre when it changes the trajectory. It is made of a sheet metal and is provided with two parallel recesses to guide the motion of the stop (7) (guiding plate) of the mechanism (6). The support plate (8) is also provided with a protrusion on one side limiting free space between a crimp ring of the larger diameter tire and the support plate (8). Unavailability of the protrusion causes blockage of the smaller diameter tyre when it enters the above space, thereby significantly complicating the packaging process.
The mechanism for compressing a smaller diameter tyre comprise two flat compressing members (10), an upper part (13), a synchronizer (15) and attachment members of pneumatic (hydraulic) cylinders.
Flat compressing members (10) are movable members and are designed to compress smaller diameter tires. They are configured as a frame construction to mount two rollers, a sliding plane and an elastic band.
The rollers are mounted in the lower and upper parts of the compression plane and serve to stretch the elastic band. The sliding surface is disposed therebetween. It is provided with a special coating reducing friction force occurring when the smaller diameter tyre is fed to the interior space of the larger diameter tyre. In this case, the friction force occurs between the sliding plane and an inner side of the elastic band which is also characterized by low friction coefficient. Therefore, the elastic band is intended to fix the smaller diameter tyre during compression and facilitates motion thereof inward the larger diameter tire. Flat compressing members are provided with assemblies designed to mount them to the upper part and with attachment points designed to connect with pneumatic (hydraulic) cylinders actuating the compressing members.
The upper part (13) is a stationary component. It comprises a frame construction to which flat compressing members (compressing planes) (10) are secured by axles. Connecting struts of the device are also secured to the upper part (13). The upper part construction is provided with attachment points of the pneumatic (hydraulic) cylinder (20) actuating the mechanism (11 ) for feeding the compressed smaller diameter tyre into the interior space of the larger diameter tyre.
A synchronizer comprises parts (15) shaped as a gear segment. The segments are fixed on axles of compressing plates and go into engagement with each other. The synchronizer (15) controls a uniform motion of the flat compressing elements (10). It is required to prevent the mechanism (11 ) for feeding and packaging the compressed smaller diameter tyre from being prematurely operated. If the synchronizer (15) is not available, this may hinder operation of the device and lead to serious damage of the smaller diameter tyre.
Attachment members of pneumatic (hydraulic) cylinders (14) actuating compressing planes may be disposed on connecting struts or on the upper part of the device.
The mechanism (11) for feeding and packaging the compressed smaller diameter tyre is a movable component. It is designed to insert the compressed smaller diameter tyre into interior space of the larger diameter tyre to be subsequently packaged in this space. This mechanism comprises a frame
construction traveling vertically along the guides. The mechanism mounts a stop in the middle to which the arched plate (12) with rounded edges is secured. The stop with plate (12) is directed toward the movable platform of the mechanism for stretching larger diameter tyre . The shape of the arched plate (12) with rounded edges prevents parts of the compressed smaller diameter tyre from entering into the space between walls of expandable grips and the plate itself during packaging.
Device Operation
To package tyres , make sure that the device is in the initial position. In the initial position, the movable platform table (3) of the mechanism for stretching a large diameter tyre (24) is at the lower position, flat compressing members (10) are opened and the mechanism (11 ) for feeding and packaging a compressed smaller diameter tyre is in the upper position. Expandable grips (4) of the stretching mechanism are closed. Such arrangement allows tyres to be packaged.
The larger diameter tyre is placed on the movable platform table (3) in such a way that the support plate (8) is disposed in the middle of the tyre (Fig. 6). Then, a pneumatic (hydraulic) valve (not shown) controlling the movable platform motion is actuated. The movable platform table (3) jointly with the larger diameter tyre (24) placed thereon begins moving upward toward the middle part (9) (under the action of pneumatic (hydraulic) cylinders (16)). When the movable platform table (3) reaches a specific level limited by a sensor (not shown), it stops (Fig. 7). The expandable grips (4) which were closed up to this point begin to expand under the action of pneumatic (hydraulic) cylinders (17) gripping the larger diameter tyre (24) from both sides (Fig. 8). Once the grip walls contact crimp rings of the tyre, the sensor (not shown) supplies a signal to operate the motion of the movable platform table (3) downward. Therefore, the tyre (24) held by grips (4) located in the middle part (9) and in the movable platform table (3) begins to stretch to acquire a volume exceeding that in the normal state of the tyre (Fig. 9). The downward travel of the movable platform table (3) is limited by maximal width of the stretched tyre. Once the platform stops and the larger diameter tyre acquires a maximal volume, the small diameter tyre may be inserted. The smaller diameter tyre (25) is arranged in a front-face position between flat compressing elements (10) over the grips (4) of the middle part (9). In this case, an angle of the plane thereof relative to the plane of the stretched larger diameter tyre (24) should be close to 90° (Fig. 10). Once the loading is completed, the
pneumatic (hydraulic) valve controlling the motion of flat compressing members (10) and mechanism (1 1 ) for feeding and packaging the compressed smaller diameter tyre into the interior space of the larger diameter tyres hould be actuated. The flat compressing members (10) begin to move toward each other under the action of pneumatic (hydraulic) cylinders (18). The cover (25) is compressed (Fig. 1 1 ). When flat compressing members (10) reach a specific position restricted by the length of a rod of pneumatic (hydraulic) cylinders (18), they stop. Synchronous with the stop of compressing members (10), the sensor (not shown) supplies a signal to operate the motion of a pneumatic (hydraulic) cylinder (20) actuating the mechanism (1 1 ) for feeding and packaging of the compressed smaller diameter tyre. Operation of the feeding mechanism (1 1 ) forces the compressed tyre (25) to move at a right angle (or an angle close to it) into the interior space of the larger diameter tyre (24) (Fig. 12). Once the compressed tyre (25) reaches the surface of the support plate (8), the mechanism (1 1 ) for feeding and packaging of the compressed small diameter tyre temporarily ceases the motion thereof. This is required to avoid unnecessary deformations which may occur upon contact of the tyre (25) with the support plate (8). These deformations may result not only in tyre damage, but also in malfunction of the mechanism (6) changing the trajectory of motion of the compressed smaller diameter tyre. The tyres cannot be effectively packaged due to the above causes. Once the mechanism (1 1 ) stops, the sensor (not shown) supplies a signal actuating the mechanism (6) changing the trajectory of motion of the compressed tyre (using a pneumatic (hydraulic) cylinder (19)). The movable stop (7) of the mechanism (6) moves a lower part of the compressed tyre (25) toward the interior wall of the larger diameter tyre (Fig. 13). Therefore, an angle between the plane of the compressed tyre (25) and the plane of the stretched tyre (24) changes from the right angle (or an angle close thereto) to an angle of 45° (or close thereto). After changing over the tyre planes to a new condition, the sensor (not shown) supplies a signal to resume the motion of the feeding and packaging mechanism (1 1 ) which moves the compressed tyre (25) further into the interior space of the stretched tyre (25). As this takes place, the mechanism (6) of changing the trajectory of motion also continues motion thereof moving a lower part of the compressed tyre (25) further toward the interior wall of the stretched tyre (24). Therefore, combined action of the above mechanisms brings the plane of the compressed tyre (25) into coincidence with the plane of the stretched tyre (24). Once the feeding and packaging mechanism (1 1 ) and mechanism (6)
changing the trajectory of motion reach a specific position limited by the length of the rod of the pneumatic (hydraulic) cylinder (20), they stop. As this takes place, a free space sufficient for complete release of the tyre (25) is available between the support plate (8) and arched plate (12) with rounded edges. The tyre (25) completely expands across the entire inner perimeter of the tyre (24) under action of internal forces. Packaging of the tyre (25) is completed (Fig. 14). Then, a reverse process takes place during which a finished package comprising tyres (24-25) is released. After this, all mechanisms of the device return to the initial position. The mechanism (1 1 ) for feeding and packaging the compressed smaller diameter tyre begins an upward motion. Simultaneously, the following mechanisms automatically return to initial position thereof: the mechanism (6) changing the trajectory of motion of the compressed smaller diameter tyre (the motion of the mechanism's stop reverses) and flat compressing members (10) (expand). When the mechanism (11 ) for feeding and packaging the compressed smaller diameter tyre reaches a specific position restricted by the length of a rod of a pneumatic (hydraulic) cylinder (20), it stops. Then, the pneumatic (hydraulic) control valve is actuated to operate an upward motion of the movable platform table (3). When it reaches a specific level limited by the sensor (not shown), the movable platform table (3) stops. The expandable grips (4) which were in the expanded condition up to this moment begin to move toward each other under the action of pneumatic (hydraulic) cylinders (17) releasing a package comprising larger and smaller diameter tyres. Once the grips fully close, the sensor (not shown) supplies a signal to operate a downward motion of the movable platform table (3). Therefore, the package comprising tyres (24-25) arranged on the table (3) becomes accessible to be unloaded out of the device. After unloading a finished package, the device is ready for further use. If an additional tyre needs to be packaged in the interior space of the package (24-25), the above process should be repeated for packaging a tyre of even smaller diameter.
Industrial use of this invention has been tested using the constructed device.
Testing the method and device has proved practicability and quality of packaging without damaging inner and outer tyres.
It will be understood by those skilled in the art that description of the specific embodiment of the device does not confine the scope of the invention and any similar embodiments may be used within the scope of original claims.
