Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a transfer device for transferring a cylindrical body such as a belt or tread band from one molding drum to another in a tire manufacturing process, for example.

Wataru Nijihisa 1 Conventionally, as a transfer device for transferring the above-mentioned cylindrical body from one molding drum whose diameter can be expanded and contracted to the other molding drum whose diameter can be expanded and contracted, for example, a transfer device installed between both bottom type drums has been used. a rail, and a conveying body that is slidably supported by the rail and has a ring portion at the top that can approach and separate from the one and the other molding drums, and the ring portion expands and contracts to move the cylindrical body outward. It has a chuck that can be gripped from the When transferring a cylindrical body using such a transfer device, first, the conveying body is brought close to one of the molding drums, and its ring portion is loosely fitted to the outside of the molding drum, and then the diameter of the chuck is reduced. grip the cylindrical body on the molding drum from the outside with a char 2, reduce the diameter of one of the molding drums, and then move the conveyor to approach the other molding drum and bring the ring part into contact with the molding drum. Next, the diameter of the other forming drum is expanded to support the cylindrical body from the inside, and the diameter of the chuck is expanded to release the cylindrical body from its grip, thereby transporting the cylindrical body. Transfer from the body to the other forming drum.

However, such a cylindrical body transfer device easily transfers the cylindrical body when one and the other forming drums are coaxial and there are no obstacles between the forming drums. However, if the axes of one and the other molding drums are not coaxial, for example parallel but separated in a direction perpendicular to the axial direction, or even if they are coaxial, a fixed device may be provided between the forming drums. In such cases, for example, it is necessary to make complicated bends in the middle of the rail, and in this case, it is necessary to move a heavy transport object along a complicated route. Therefore, there are problems in that the overall equipment becomes larger and the 812 transport time takes longer, reducing work efficiency.

This invention has a simple structure and is compact in that when the image forming drums are not coaxial or when there is an obstacle between the two bottom type drums, the cylindrical body can be moved from one forming drum to the other while maintaining accuracy. The purpose of the present invention is to provide a transfer device that can transfer with high efficiency.

This purpose is to provide one base that can be moved relatively close to and separated from one molding drum, another base that can be moved relatively close to and separated from the other molding drum, and one base that can be moved relatively close to and separated from the other molding drum. It has a chuck that can be placed on a base and can grasp the cylindrical body from the outside by receiving a driving force from the base and expanding and contracting when placed on the base, and it can be removed from the base. A ring body that can maintain the chuck in a state where it grips the cylindrical body when it is removed, and a ring body that is provided between one base and the other base and that is capable of keeping the chuck gripping the cylindrical body on one side. This can be achieved by including a transport mechanism that transports an empty ring body from one base to another base or from another base to one base.

1. When transferring a cylindrical body from one molding drum to the other, first place the ring body on one base.0 Next, place the ring body on one base on which the ring body is placed. and one of the molding drums are brought relatively close to each other, and the ring body is loosely fitted into the molding drum.

Next, the diameter of the chuck is reduced by the driving force from the base, and the cylindrical body on one of the molding drums is gripped from the outside by the chuck. At this time, one of the molding drums is reduced in diameter and the cylindrical body is transferred from the molding drum to the ring body.
Next, one of the bases, the ring body, the cylindrical body, and one of the molding drums are relatively separated from each other.Next, after the ring body holding the cylindrical body is taken out from the one base by the conveyance mechanism, , and then transported to the other base and placed on the other base.

When the ring body is transported by this transport mechanism, the ring body is removed from either base, so it cannot receive the driving force from the base, and as a result, the diameter of the chuck expands and the cylindrical body is released from the grip. However, in this invention, when the ring body is removed from the base, the chuck is maintained in a state in which it grips one cylindrical body, so the occurrence of the above-mentioned situation is avoided. Next, the other base, ring body, cylindrical body and the other molding drum are brought relatively close to each other, and the cylindrical body and ring body are loosely fitted into the other molding drum. Next, when the diameter of the other molding drum is expanded and the chuck of the ring body is expanded in diameter by the driving force from the other base, the cylindrical body is transferred from the ring body to the other molding drum. In this way, the cylindrical body is transferred by removing the small, lightweight ring body that only has the function of gripping the cylindrical body from one base and transporting it to the other base, so that the forming drum can One cylindrical body can be easily transported even when the cylinders are not coaxial or there are obstacles along the way.

On the second band forming drum 27 side, the following operations are performed simultaneously with the winding of the belt plies v1, v2 and the tread T (forming of the band U) onto the first band forming drum 26. That is, first, the transport mechanism
161, the empty ring body 46 is carried into the second base 38I located at the take-out position F and placed thereon. At this time, the fitting protrusion 57 of the ring body 4B is fitted into the fitting hole 4o of the second base 38, and the ring body 4B is accurately positioned with respect to the second base 38, and the connection port 41. 5
8 are connected to each other, and it becomes possible to apply driving force (air power) to the cylinder 54 of the ring body 46.

Next, the piston rod 2 of the cylinder 29 protrudes, and the second
The band type machine 21 moves to the left and approaches the ring body 46 on the second base 38. Then, when the second band forming drum 27 moves by the distance ML and reaches the take-out position F, the movement of the second band forming machine 21 is stopped. At this time,
The second band hollow-shaped drum 27 is loosely fitted into the ring body 46 and the band U, and the switching valve is switched so that the air source is connected to the second base 3 through the connection port 41.58 and the hose.
Driving force (air) is supplied to the cylinder 54 of the ring body 48 on the top. As a result, the piston rod 55 of the cylinder 54 protrudes, the cam ring 49 of the ring body 4B rotates, and the respective char segments 52 move radially inward in synchronism, causing the char 53 to contract in diameter. The diameter reduction of the chuck 53 stops when the inner periphery of the chuck segment 52 comes into contact with the outer periphery of the band U.Next, when the second band hollow-shaped drum 27 reduces its diameter, the band U is stopped when the inner periphery of the chuck segment 52 comes into contact with the outer periphery of the band U. Next, the piston rod of the cylinder 2S is transferred from the mold drum 27 to the chuck 53 of the ring body 46, and the second band mold drum 27 moves to the right and returns to the supply position ME.

Next, the ring body 46 gripping the band U from the outside is taken out from above the second base 38 by the transport mechanism 161. At this time, the ring body 4B is removed from the second base 38 and cannot receive the driving force (air power) from the second base 38, so the chuck 53 expands in diameter and the band U However, in this embodiment, when the ring body 46 is removed from the second base 38, the spring 60 presses the chuck 53 against the band U. Since the grip is maintained, the above-mentioned situation is reliably prevented. The winding of the belt plies Vl, V2 and the tread T onto the first band forming drum 26 described above is a work, and the second
The work of taking out the band U from the band forming drum 27 using the ring body 46 is performed at the same time, but since the cycle time of these works is almost the same, the first band forming drum 26 and the second band forming drum 26 are 27, there was almost no loss time.

Next, the rodless cylinder 17 is actuated to move the second traveling cart 13 to the left by twice the distance, and the cylinder 29 is actuated to move the second band forming machine 21 by a distance ftL.
move it only to the left. As a result, the second band forming drum 27 moves from the supply position E to the supply position A, and then transfers the belt ply v1 from the belt ply supply means 1 to the second band forming drum 27.
After being supplied to the band forming drum 27 and wrapped around it, the cylinder 28 is actuated to move the second band forming drum 27 to the right by an equal distance. As a result, the second
The band or mold drum 27 is moved from supply position A to supply position B. In this state, the belt ply v2 is supplied from the belt ply supplying means 2 to the second band-shaped drum 27, and is wound over the belt ply v1.

In this way, the second band hollow-shaped drum 27 is connected to the second moving means 3.
1 ff1t moves one after another to the supply positions A and B of the belt ply supply means 1 and 2, and at each supply position A and H, different types of belt plies Vl and V2 from the belt ply supply means 1 and 2 are distributed around the belt ply supply means 1 and 2, respectively. Wound sequentially.

Next, the rodless cylinder 17 is actuated to move the second traveling trolley 13 to the right a distance l! IIL and move the second band hollow drum 27 from supply position B to supply position 1.
Next, the tread T is supplied from the second tread supply means 4 to the second band hollow drum 27, and the second band forming drum 27 is moved to the second drive section 2.
5, and the tread T is wrapped around the belt plies Vl and V2 on the second band forming drum 27 in an overlapping manner. As a result, a band U is formed around the second band hollow-shaped drum 27.

On the first band forming drum 26 side, the belt ply V1. V2
The following operations are performed simultaneously with the winding of the tread T (forming of the band U). That is, first, the empty ring body 4B is carried by the transport mechanism 181 onto the first base 37 located at the take-out position WD and placed thereon. At this time, the fitting protrusion 57 of the ring body 48 is fitted into the fitting hole 40 of the first base 37, and the ring body 48 is accurately positioned with respect to the first base 37, and the connection port 41. 58

Next, the piston rod of the cylinder 28 protrudes, and the first band forming drum 2B moves rightward by a distance IaL and reaches the take-out position. At this time, the first band forming drum 26 is loosely fitted into the ring body 46 and the band U. Air is supplied to the cylinder 54 of the ring body 46, and the diameter of the chuck 53 is reduced. While gripping from the outside, the first band forming drum 2B
is reduced in diameter, and the band U is transferred from the first band forming drum 26 to the ring body 46. Next, the cylinder 28 is activated and the first band forming drum 2B is moved to the left by the distance. Return to supply position C.

Next, the ring body 46 gripping the band U from the outside is taken out from the first base 37 by the transport mechanism 1fil. At this time, since the spring 60 maintains the chuck 53 in a state in which it grips the band U, even if the ring body 46 is taken out from the first base 37, the band U will not separate from the chuck 53 in the same way as described above. There is no belt ply V1. ．． Wrapping of V2 and tread T is done during work and first
The work of taking out the band U from the band forming drum 2G using the ring body 46 is performed at the same time, but since the cycle time of these operations is almost the same, the first band forming drum 26 and the second band forming drum 27 Here, the above-mentioned "simultaneously" means that the /\and type in the first band forming drum 2B and the taking out of the formed band U in the second band forming drum 27 are also Second band forming drum 27
It goes without saying that the band forming in , and the taking out of the formed band U in the first band forming drum 26 may start and end at the same time in the same cycle time; This includes cases where one of the tasks starts or ends earlier due to different timings, in other words, there are times when both tasks are progressing at the same time.

This is the first. This is one cycle of operation centered on the $2 band forming drums 26 and 27, but the same cycle is repeated thereafter to form bands U one after another, and the formed bands U are transferred to the first band forming drum 26. and the second band drum 27 are taken out alternately. In this embodiment, the belt ply supplying means 1.2, which has a large number of units, is shared by two band forming drums 26,27.
The overall structure of the device is simplified and downsized, and ply replacement work when changing sizes is also facilitated. Moreover, even if one of the /kund molding drums 26, 27 or tread supply means 3, 4 breaks down,
The remaining band forming drum 26.27. Since the tread supply means 3 and 4 can continue band forming without being affected by the above-mentioned failure, there is no possibility that the entire apparatus will stop due to a partial failure.Furthermore, as mentioned above, the belt ply supply means Although it is thought that there will be loss time if 1 and 2 are shared, we have prevented the occurrence of loss time as much as possible by performing belt ply winding, tread winding, and band removal at the same time, so there is no possibility that production efficiency will decrease.
