[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for exchanging a tire building drum and a conveying apparatus for a forming drum used therefor, which greatly improves the efficiency of exchanging a tire building drum.

[0002]

2. Description of the Related Art In order to replace a used tire building drum attached to a tire building machine body with a tire building drum for the next use, conventionally, a hoisting device such as a chain block or a hoist has been used. With the used tire building drum supported, the tire building drum is separated from the output shaft of the molding machine by hand, and transported to the required standby position under the action of a chain block, etc. The tire building drum according to the next use is transported from its standby position or the preparation position to the vicinity of the main body of the forming machine with a chain block or the like, and the position and the position of the tire building drum are corrected, and It is common to align the forming drum with the output shaft, and then manually connect the forming drum to the output shaft. .

[0003]

For this reason, in this prior art, a hoisting device such as a chain block at a standby position is used for separating and discharging a used tire building drum, and
It is necessary to make one reciprocation every time the next used tire building drum is directly connected, and the next use of the tire building drum, which has been transported to the vicinity of the molding machine body, is sufficiently accurate to the output shaft. Usually, it is necessary to correct the position a plurality of times in order to align the tires, which has the problem of reducing the efficiency of replacing the tire building drum. If high,
This is particularly important when the tire molding machine is expensive.

An object of the present invention is to solve such problems of the prior art, and an object of the present invention is to use a used tire building drum and a tire building drum to be used next. An object of the present invention is to provide a method for exchanging a tire building drum, which can easily and easily perform exchange with a drum with high work efficiency, and a molding drum conveying device used for the method.

[0005]

A method for replacing a tire building drum according to the present invention has at least one drum mounting space for supporting a tire building drum newly mounted on a molding machine body in a horizontal posture. The support base having one or more empty spaces for receiving used tire building drums to be removed from the molding machine body is translated so that a specific tire building drum to be mounted next is already attached to the molding machine body. The used tire building drum is positioned parallel to the used tire building drum, and the empty space drum support is brought into contact with the used tire building drum, and then the used tire building drum is separated from the output shaft of the molding machine body. Then, the specific tire building drum to be supported by the drum supporting portion in the empty space and the mounted Orthogonal is displaced in the direction of, the drum axis, is aligned with the axis of the output shaft of the molding machine body,
In this state, a specific tire building drum is connected to the output shaft, and the used tire building drum received in the empty space is transported to the standby position by the translation of the support base.

According to this method, the empty space is brought into contact with the used molding drum by a translational movement of the drum mounting space on the support base, which actually supports the tire building drum, and the empty space. Then, the used molding drum is separated from the molding machine main body. Subsequently, the tire mounting drum mounted on the drum mounting space is moved, for example, based on its horizontal displacement, so that the drum axis is aligned with the molding machine main body. In addition to the posture that is aligned with the axis of the output shaft, and connected to the output shaft, as in the prior art,
A plurality of reciprocating transports by a chain block or the like can be omitted, which is particularly effective when the support base has two or more drum mounting spaces.

[0007] Here, in addition to the respective translational movements of the support base, based on, for example, horizontal displacement of a specific tire building drum to be mounted in a direction perpendicular to the drum axis.
By specifying each final stop position by a positioning means or the like, it is possible to eliminate the necessity of a plurality of times of position correction and posture correction as in the case of using a chain block or the like.

Thus, according to the present invention, the removal of the used tire building drum from the molding machine main body and the connection of the tire molding drum to be used next to the molding machine main body, and thus the tire Replacement of the molding drum can be performed easily and quickly, and the replacement work efficiency is improved.
It can be greatly improved as compared with the prior art.

Here, when the used tire building drum is separated from the output shaft of the molding machine main body, the used building drum is displaced backward in a direction away from the molding machine main body. When connecting the output shaft to the output shaft, when the forming drum is advanced and displaced toward the forming machine main body side, the output shaft and the tire building drum can be fitted and connected by a flashing portion, and the connection accuracy can be improved. Improvement and dispersion support of the load on the molding drum side can be effectively realized.

[0010] To achieve this, specifically, an independent plate provided with an empty space on the support base is brought into contact with the used tire building drum of the empty space drum supporting portion prior to contact. In order to separate the tire building drum from the output shaft while retracting the tire building drum from the output shaft in advance, the used tire building drum is provided with the expected removal force without twisting, etc. In order to smoothly work on the tire, the other independent plate, which is provided on the support base and has a drum mounting space, is connected to the molding machine main body side when the specific tire building drum is connected to the output shaft. The advance displacement is preferable in order to realize a smooth fit of the next mounted drum mounted on the drum mounting space to the output shaft. .

Incidentally, when the drum support portion in the empty space is brought into contact with the used tire building drum, the translational movement of the support base is caused by one-dimensional or two-dimensional linear displacement in a horizontal plane and the support base. Itself or
It can be a combination with the upward displacement of the empty space drum support, in which case the upward displacement is performed last. Here, when the support base is caused to perform only one-dimensional linear displacement, the displacement direction is the used tire building drum mounted on the molding machine main body, in other words, the direction of the axis of the output shaft of the device main body or the direction orthogonal to the direction. When two-dimensional linear displacement is performed, the two directions are used.

When the used tire building drum received in the empty space is transported to the standby position, the translation of the support base is caused by the downward displacement thereof and the linear displacement in one or two dimensions in a horizontal plane. Or only linear displacement of the support base in one or two dimensions in the horizontal plane, in which case the descending displacement is performed first. The direction of the linear displacement of the support base is the same as described above.

In the above-described method for replacing a tire building drum, in a case where the tire building drum is rotated and displaced in a plane perpendicular to the axis thereof, a specific tire to be newly mounted is used. Prior to aligning the axis of the molding drum with the axis of the output shaft of the molding machine, rotate the axis of the output shaft 180 ° around a center of rotation outside the output shaft in a plane perpendicular to the axis. Dynamic displacement.

According to this, for example, the support base is
When there is one drum mounting space and one empty space, the movement area of the support base can be substantially contained in the rotation area of the tire building drum attached to the molding machine main body. The entire exchange device can be made sufficiently small, and only the interference of the support base and the tire building drum supported thereon with other members can be effectively eliminated.

[0015] The conveying device for a molding drum according to the present invention comprises:
At least one independent plate provided with a drum mounting space for horizontally supporting a tire building drum newly mounted on the molding machine body, and an empty space for receiving a used tire building drum removed from the molding machine body. And at least the other independent plates extend in parallel with each other, and these two plates are disposed on a horizontal support base so as to be individually movable in the extending direction thereof,
The support base is disposed so as to be horizontally displaceable at least in a direction orthogonal to the central axis of the independent plate. According to this device, the drum exchange can be performed easily and quickly.

Here, in order to automate the drum changing operation, each drive means for moving the independent plate forward and backward is provided on the support base, and the drive means for horizontally displacing the support base is provided with a guide frame of the support base. Further, it is preferable to provide a drive means for vertically moving the respective drum supporting portions of the drum mounting space and the empty space on each independent plate, and to provide these portions in a predetermined order in a predetermined order based on sequence control or the like. Is preferably displaced. In addition, instead of or in addition to the above-described lifting / lowering driving means of the drum support portion,
Driving means for raising and lowering the support base itself may be provided.

Here, when the support base can be displaced horizontally also in the center axis direction of the independent plate, the degree of freedom of the support base can be further increased, and the drum replacement operation can be performed more smoothly. Further, when the driving means for this horizontal displacement is provided on a fixed base that supports the guide frame, the horizontal displacement of the support base can be performed as required at a required timing.

By the way, in this device, the support base is arranged on the bogie via a linear motion guide for guiding a horizontal displacement of the support base in a direction orthogonal to the center axis of the independent plate, and the support base is attached to the support base. It is also possible to provide a lifter to be displaced up and down together with the trolley, on the fixed base or the trolley, in which case, the support base is moved to the expected position at the required timing under the action of the trolley wheels, At a predetermined drum replacement position, the support base can be raised and lowered to a required position by a lifter. And here also, a drive means for vertically moving each drum support independently of the operation of the lifter can be provided.

Here, when a guide means for guiding the rolling path of the bogie wheels is provided and a stopper for specifying the forward limit of the bogie is provided, the bogie itself is positioned at the drum replacement position. The accuracy can be increased, and when the bogie under the action of the lifter, and thus the positioning means for specifying the upper limit position and the position in the horizontal plane of the support base are provided, the support for the drum replacement operation is provided. The positioning accuracy of the base and the independent plate can be improved, and the operation can be performed more smoothly and easily.

When the position specifying means for positioning the lifter and the truck or the fixed base in the horizontal plane is provided, the positioning of the truck at the upper limit position can be advantageously assisted.

[0021] More preferably, means for positioning the tire building drum in the circumferential direction is provided on the drum support provided in the drum mounting space. According to this, the tire building drum newly mounted on the output shaft of the molding machine main body can be always aligned with the output shaft in a fixed posture by the action of the circumferential direction positioning means. Their interconnection, for example by means of bolts and nuts, can be performed easily and quickly with a reliable alignment of the bolt holes with each other.
