Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for transporting green tires into a left and right two-chamber TAICE vulcanizer.

In Figure 1, the tie 1 is vulcanized at Res A. An example of a conventional green tire loading device is shown.

One tire vulcanizer is equipped with two sets of tire molds, making it possible to vulcanize two tires at the same time, creating a so-called two-chamber tire vulcanizer.

When carrying in green tires, the green tire carrying device is used to transport green tires by a combination of vertical movement in the up and down direction and horizontal rotation, as shown in Figure 1. Carrying device B1. B2 is provided separately for each.

In this way, it is necessary to have separate transport devices for the left and right sides.

(1) Separate lifting and turning drive sources for the green tire loading devices Bl and B2 and turning drive sources are provided for the left and right sides, which has the disadvantage of high equipment costs.

(2) The green tire loading device is not only required to hold and standby the green tire to be vulcanized next while the green tire is being vulcanized on the press side. It is necessary to store the vulcanized material in the next step, and the following two types of storage have been conventionally adopted.

The first type, as shown in FIG. 1, is a type in which a green tire stand is fixedly installed at the position (3) in front of the seat, and green tires are stored on the green tire stand. In this case, the green tire to be first vulcanized is suspended and held at the green tire loading position, and
It is said to be in an upper position.

While the vulcanized tire is in the upper position, the "green tire to be cured next" is placed on the green tire stand at the lower position (■).

However, in this case, there needs to be sufficient vertical clearance between the green tire that has already been suspended and the green tire stand in order to facilitate the work of installing the green tire. It needs to be sufficiently higher than the stand.

On the other hand, in the case of a vulcanizing press with only vertical movement, which has recently been considered preferable as a high-precision tire vulcanizing press, it is necessary to reduce the vertical stress of the tire in order to improve productivity and maintain high precision for a long period of time. As mentioned above, if the green tire loading device is left as it is, as it is designed to be as small as possible
There was not enough vertical clearance between the suspended and gripped green tire to be cured and the green tire stand to place the green tire to be cured next. For the preparation work, we gave the green tire loading device an extra stroke and raised it once to a high position for the preparation work, and after completing the first work,
This creates a need to perform a complex vertical operation of lowering and waiting at a lower position suitable for loading.

In addition, since the vulcanizing press is designed to be able to vulcanize tires of two different sizes, the tire mold is changed depending on the tire size to be produced. At this time, the raw tire holder is placed at the front of the press. Since the mold is installed in the middle of the mold, it interferes with the replacement work of the mold, so it is made to be a removable mold, or a type that can be swung to a position where it does not interfere only during the second work is adopted.

Therefore, this type of green tire delivery.

The accumulation method cannot be said to be suitable for a vulcanizing press with only vertical motion.

The second format is in the first format described above.

(b) Large stroke 0- in the vertical process of the green tire loading device
Requires maintenance.

(0) Controlling the vertical movement of the green tire loading device is complicated.

(At the time of replacing the mold, it is necessary to perform special operations on the raw tire stand to place it in an unobstructed position.

In order to solve the above drawbacks, the raw tie P mounting table is designed to be able to swing back and forth between the position ◯ and the position ◯ shown in Fig. 1. In the case of this type, although the above-mentioned (1(01(IN) problem is certainly solved, it becomes necessary to swing the left and right raw tire stands, making it difficult to use the same drive source for the left and right sides, and increasing the equipment cost. It has the disadvantage of being high.

(3) Furthermore, if the preparation work for green tires is performed at position ■, as can be seen from Figure 1, the space required for the vulcanization press increases, and the In cases where ten or more presses are arranged in a straight line.

(very commonly practiced) resulting in long space-consuming defects.

(4) Furthermore, since the vulcanizer is fully automated, from loading the raw tires to the unloading of the finished tires once the raw tires are supplied onto the raw tire rack, it is possible to automatically place the raw tires onto the raw tire rack. Research on distribution and installation is underway. However, as described above, if the green tire stands are separated on the left and right sides of the press, it is not suitable for automatic installation from the automatic green tire distribution equipment. That is, the automatic dispensing equipment stops at a position in front of the corresponding press and returns too far to place the green tires, and as a result, it becomes necessary to stop at a position in front of each green tire placement platform, which causes the machine to stop twice in front of the press. This results in problems such as long stoppages and complicated control.

The present invention has been proposed in view of the above-mentioned points, and its purpose is to transport green tires into the left and right chambers of a two-chamber tire vulcanizing press.

(1) At least, the vertical movement of the green tire loading device for each of the left and right rooms is performed using the same vertical vertical track and vertical vertical drive device to reduce equipment costs.

(2) The turning operation of the raw tire stand should be performed by the same drive device for the left and right sides, thereby reducing equipment costs.

(3) To provide an economical vulcanizing press with a smaller overall width than the space required for conventional vulcanizing presses, which requires less installation space.

(4) Automatic distribution of green tires and tire vulcanization that is convenient for installation. That is, when automatically distributing green tires onto a green tire stand and installing green tires by an installation device, the automatic installation device should be stopped at only one position in front of the press concerned.

It is in.

Therefore, the present invention is a tire vulcanizing press with two left and right chambers, in which a device for carrying green tires into each chamber is movably installed in the center of the press, and a stand for placing green tires is placed in the front position of the center of the press. It is movably installed, and the front position of each of the chambers is set as a standby position for the carrying-in device, and the front position of the center portion of the seat is set as a position for supplying raw tires to a raw tire stand.

1. whether the carrying-in device is moved to the tire supply position;
Alternatively, the method relates to a method for transporting raw tires, characterized in that the raw tire stand is moved to the standby position, the raw tires are received, and the raw tires are transported.

In addition, the present invention provides a tire curing press with two left and right chambers, in which a movable member that can move up and down in the vertical direction is provided in the central frame of the press, and the movable member is provided with a left and right pair of green tire gripping devices at one end. This invention relates to a green tire loading device having a rotatable arm.

Furthermore, the present invention provides a tire vulcanizing press with two left and right chambers, in which a movable member that can move up and down in the vertical direction is provided in the central frame of the press, and the movable member is provided with a left and right pair of green tire gripping devices at one end. The arm is rotatably provided and is located at a position in front of the center of the press, between a green tire supply position in front of the center of the press and another position, or between the green tire supply position and a carry-in standby position in front of each left and right chamber. This invention relates to a raw tire loading device characterized by being provided with a pair of left and right raw tire loading stands that are movable between the green tire loading stands.

The present invention will be explained below based on examples.

In Figure 2, A is a two-chamber tire curing press*
a, 82 is set at the center of the press -6.

This device is used to transport green tires into the left and right chambers where the tires are placed.As will be described later, this device is movable vertically up and down, and can be moved between one position, which is the center of the press mold, and the waiting position in front of the mold. It is possible to turn in the horizontal direction between the n position and the n position, or from the first position to the green tire supply position via the n position.

FIG. 6 shows the specific configuration of the above device, and the AI
is a single-acting type with vertical movement only, two chambers on the left and right, and has a side frame section on the right side of the left and right sacrum parts, and a center frame and A2 in the center of each chamber. The equipped green tire loading device is shown.

1 is a common base plate attached to the sector frame A2, and the base plate 1 has brackets la at its upper and lower ends.

1b.

On the base plate 1, a linear track 2 of what is commonly referred to as a lin-a-t-shoshi bear sig is fixed, which is arranged parallel to the center axis (vertical axis) of the press mold.
A trolley 3 is fixed to the mat. In this example, it is assumed that two sets of bare sign nuts are installed on each of the left and right tracks.

A nut (not shown) is fixed in place on the trolley 3, and a threaded rod 5 engaged with the nut is attached to the bracket Im.
, Ib is rotatably mounted.

An output shaft of a rotary drive device 6 is connected to an end of the threaded rod 5 protruding from the bracket 1a. Note that the drive device 6 is fixedly installed on the racket 1a.

The trolley 3 includes brackets 3a and 3b.

A known green tire gripping device C as illustrated in FIG. 3(,)
An arm 7 is rotatably mounted thereon.

Figure 3 (tb) shows a rotatable mounting structure.

It shows the state when the trolley 6 is at its lowering limit.

The arm 7 has a base boss 7a supported rotatably with respect to the brackets 3a, 3bK by a pairing 8, and the bearing 8 supports the brackets 1-3a, 3b as shown in the figure so that the arm 7 does not move in the vertical direction. is equipped with.

Further, inside the boss portion 7a, a bushing 9 is fixed to the arm 7 in a non-rotatable manner by a known method, and this bushing 9 has a square hole as shown in FIG. A square bar 10 is assembled that can engage and slide in the hole.Both ends of the square bar 100 are rotatably mounted on the brackets 1a and 1b, and an arm is attached to the downwardly protruding end of the bracket 1b. 11 is fixedly installed.

The arm 11 is rotatably connected to the D/Sodo end of a syringe 12, one end of which is rotatably mounted on a frame.

According to this structure, the drive device 6 can arbitrarily move and stop the carriage 6 vertically and up and down, and the syringe 12 can independently rotate the left and right arms 7 regardless of the positions of the two carriages 3. In other words, the left and right green tire loading devices can be vertically raised and lowered by one drive device, which is economical, and the swing drive device (in this example, the syringe 12 is located on the press frame side, so the piping of the syringe 12 can be moved up and down). There is no need to move up and down accordingly (this prevents troubles such as damage to piping hoses).

Here, the cylinder 12 is connected to the first raw tie t), which will be described later. When the loading method is adopted, the loading device is the I
, It, and I are operated, and when the second raw tire loading method is adopted, the control is operated to perform two-position control 1 and II shown in FIG. 2.

Figure 4 is an explanatory diagram of the attachment of the common base plate 1 to the press frame A2.The common base plate 1 is equipped with a number of equipment as shown in Figure 3, but only the base plate 1 is omitted. is shown, and the lower end of the common base plate 1 is connected to the appropriate position of the center frame A2 with a pin 713,
The biscuit 13 is fixed to the press frame A2. Further, the bracket 14 is incorporated at the upper end of the common base plate 1 and is fixedly installed at a suitable position on the upper end of the turf.

Therefore, when the sesquiturm A2 expands or contracts, the base plate 1 can slide on the bracket 14, and no force is generated due to the expansion or contraction.

This means that in a frame-type vulcanizing press with a gate-shaped frame type in which a pressure reaction force of JL7 is applied to the vertical frame, the 1-f loading device is This provides a new mounting method for mounting on a vertical frame. That is, in the case of the above-mentioned vulcanizing press, distortion occurs in the vertical frame as pressure is applied, and the elongation of the frame 6 in the vertical direction occurs in proportion to the quantity, and when the pressure is released, this vertical frame The frame elongation decreases and returns to the original state.

If the plywood of the green tire loading device is fixed to the vertical frame, which expands and contracts repeatedly in this way, with bolts, etc., a large force will be applied to the bolts when pressurized. This may cause the bolts to become loose or the bolts to be damaged. Therefore,
When attaching the green tire carrying device to a press frame that repeatedly expands and contracts due to press force, one end of the plywood of the green tire 4P carrying device should be installed in a free state relative to the direction in which the press frame stretches, so that there is no strain on the mounting area. This is effective in preventing the generation of force and providing a long-life green tire loading device.

The structure related to this fastening part is not limited to presses in which the green tire loading device is installed in the center of the press, but also in presses in which the green tire loading device is installed at the left and right positions of the press. Needless to say, this method is often used when mounting plywood of a tire loading device on a press frame that repeatedly expands and contracts.

Next, a first embodiment of a raw tire stand for supplying raw tires will be described with reference to FIG.

As shown in FIGS. 5(a) and fb), the pair of left and right mounting stands 20, 21 are attached to the same arm 22, which is installed on the floor in front of the center of the press.

It is rotatably mounted on a pedestal 25 having a known rotary mechanism (not shown).

When this green tire loading stand is used in the first carrying method described later, when the green tire carrying-in device B comes to the 1st position, the center of the green tire carrying-in stand 20 is at the 1st position. When B2 comes to the I position, the center of the mounting stand 21 (fit
When the table 2o is in the 1 position, the coordinates of the center of rotation (with respect to ``5'') are set in stages so that the table 2o is rotated by 180° and brought to the rest position.

In addition, when using the second loading method described later, when each green tire loading device BI+B2 is in the 1 position and the green tire loading platform is turned 90 degrees from the state shown in FIG. 5 taJ, each loading platform 20, 21 medium equipment.

Day 6220 rotation radius 9 rotation center coordinates are designed so that tV coincides with one position of each green tire carrying device B, , B2.

When using the above-mentioned green tire loading platform in the first green tire loading method described later, when the loading platform 20 or 21 is in the 1 position, the distance from the center of the press can be shortened;
It is necessary to control the position of the carry-in device Bl + B2 by three-position control.

On the other hand, when using the second green tire carrying method, the green tire carrying device B+, B2 may be controlled at two positions, whereas in the case of the first method, the rotation center of the green tire stand may be controlled at two positions. Figure 5 (further forward of the press from the a1 position,
Also, make the turning radius of the raw tire stand a little larger than in the first method.

It is necessary to move each n position of the green tire carrying device closer to the ■ position, and the space required in the front direction of the press becomes a little thicker.

On the other hand, the method shown in Figure 6 is green tire transport method B.
1, B2 position control is 2 position control (.

In addition, the space required for the green tire 'pif stand in the front direction of the press can be the same as in the case of the first loading method, which is an even better feature. 20 and 21 are attached to the same arm 24, and this arm 24 is rotatably mounted on a bracket 25 at the lower front of the press frame A2. Also.

A press frame A is attached to one end of the arm 24 in a proper position.

The zero end is rotated around the arm 24 so as to be able to swing freely. A rotatably mounted syringe 26 is attached.

When the holder 20 is in the 1 position, the other holder 21 is at the lower position corresponding to the n position of the right raw tie P carrying device B, the syringe 26 is extended, the arm 24 is rotated, and the holder 2o is moved to the left side. When the inner tire loading device B is at the lower position corresponding to the n position, the placing stand 21 is at the 1 position.

Furthermore, the one shown in FIG. 7 requires less space in the front direction of the press than the one shown in FIG. 6.

As shown in FIG. 7, the mounting stands 20 and 21 are mounted on the same table 27, and the linear trajectory 2 of what is commonly called a linear T-sho: J pair: Niji is placed on the bottom surface of the same table 27.
A bearing link nut 28b, which is engaged with the track 28a, is fixed on the upper surface of a pedestal 29 fixed on the floor in front of the press.
A rack dea 50 is fixed at a proper place on the lower surface, and a biniosi f aro 1, which is engaged with the rack f aro 0, is attached to the output shaft of a rotary drive device fixed to a pedestal 29. The rack a29 and the track 28a are arranged so that the centers of the stands 20 and 21 are parallel to the center line of each chamber of the press.
The center line at the position is matched with the center line of the green tire stand, and the distance between the centers of the green tire stand is 172, which is the distance between the centers of the green tire loading method at the n position. The limits of movement of the table 27 in both left and right directions are as follows. That is, when the table 27 moves to the left, the center of the stand 20 is at the center of the carry-in device B, and the center of the stand 21 is at the n position, and when the table 27 moves to the right, the center of the stand 20 is at the center of the carry-in device B. is at the central position, and the center of the stand 21 is the center of the general access device B2. Therefore.

In one position, raw Nui P can be sequentially supplied to each placing table.

The supplied raw ties P can be delivered to each of the carry-in devices B, , B, at each n position. For this reason, it will be understood that the raw tie PifIi press machines B and B2 can be controlled in two positions at the I and 11 positions, and the space required in the front direction of the press is smaller than in any of the above cases. .

Furthermore, when replacing the mold, it should be understood that in any of the above cases, the green tire stand does not obstruct the mold replacement work. That is, the case shown in Fig. 5 is vulcanized-3.
(In the case of the one shown in Figure 6, when replacing the left mold, replace the mold on the right as shown in Figure 6 1al). When replacing it, just do it in the opposite direction (in the case of the one shown in Figure 7).

When replacing the left mold, please refer to Figure 6g7 (al).

For the right side, do the opposite.

Next, a 10th green tire transport method for transporting green tires using the green tire transport device shown in FIG. 2 and the green tire stand shown in FIG. 5 will be described in detail.

(1) The katai P is equipped with up to four vulcanizing presses during vulcanization, which does not prevent fully automatic operation of the vulcanizing presses.

(2) It is possible to raise and lower the green tire loading devices B, , and B using the same lifting drive device, thereby providing an economical 16-person device.

(3) Since the two sets of stands 20 and 21 can be moved by the same drive device, an economical green tire stand can be achieved.

(4) The installation of green tires on the green tie device table is carried out at the central part (i) of the tie.

(5) Since the replenishment of green tires is not carried out at a position below the raw tie 1-I suspended in the clamps, the upward stroke of the raw tie 1-I & one-man device is small, making it possible to provide an economical carrying-in device.

(6) Since the green tire carrying device and the raw tire 1 straight stand are placed in the center of the zure, the entire width of the zure is shorter than when the left and right sides are separated, and less installation space is required.

(Power) When replacing the mold, there are no obstacles on the front of the press, allowing for efficient replacement work.

(8) Since the drive source for the swing motion of the green tire loading device is located on the side of the frame, there is no need to move the wiring or piping of the swing drive device as it goes up and down, resulting in improved durability and It is excellent in terms of safety.

(9) The attachment points of the two plywood sheets of the green tire loading device to the press frame are movable, so even if the press frame expands and contracts, no force is generated at the attachment points, reducing the accuracy of the 112-man device. Let's do it.

Will not be damaged.
