[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a process for supplying a large number of white tile groups (hereinafter simply referred to as "tiles") conveyed by a so-called upright conveyor before a firing step to a firing step or a firing step. The present invention relates to an improvement in a tile-sintering spacer mounting apparatus for mounting a tile-sintering spacer used for preventing a group of tiles from overturning on a tile standing on an upright conveyor.

[0002] In this specification, a tile firing spacer 8 is used.
Is used in a ratio of one to six or ten tiles W. The whole is elongated and one side is formed in a comb-shape, and it stands upright at an interval of about 2 to 5 cm. A groove 11 having a semi-elliptical opening is attached to an upper portion of the tiles W arranged in a row so as to maintain a gap between the tiles W, particularly at the upper portion, and to be used in a firing process or the like. This prevents the W group from falling down (see FIG. 4, Japanese Patent Publication No. 58-30519).

[0003]

2. Description of the Related Art Roof tiles are manufactured by transferring tiles having undergone molding, drying, glazing, etc., to a firing step. In general, in these steps up to the firing step, the tile W is in a horizontal state. But,
During firing, Kawaragun on prior advance called upright carrying conveyor mounted to the baking carriage for improving of tile firing efficiency are loaded into the firing carriage by orderly erected one by one.

[0004] The baking cart with the group of tiles mounted in an upright state is introduced into a baking furnace, and the group of tiles on the baking carriage moving in the furnace, though gently, is fired in the upright state. Hot air is introduced in between, and the group of tiles is fired to produce a product.

[0005] Therefore, at the time of firing on the firing carriage in the furnace of the group of tiles or moving the group of tiles in the furnace, measures to maintain a reasonable interval for introducing hot air to the group of tiles in the standing state and to prevent the tiles from overturning. There was a problem that measures had to be considered.

In order to solve this problem, a device disclosed in Japanese Patent Publication No. 58-30519 has been known.

A take-out mechanism for sequentially projecting the comb-shaped spacers one by one and feeding them into the guide groove, a transfer mechanism for feeding the comb-shaped spacers in the guide groove to a predetermined position in the guide groove, and a guide A vertically movable chuck device for grasping a comb-shaped spacer reaching a specified position in the groove, and a reciprocating device for reciprocating the chuck device from the specified position to the mounting position of the comb-shaped spacer on the roof tile. It consists of:

However, in this type of conventional apparatus, although it is possible to hold the comb-shaped spacers one by one with a chuck device and mount them on the tiles on the conveyor, the intervals between the tile groups are equally spaced. Therefore, there is a problem that it is necessary to prepare a considerable number of other spacers between the tile groups in order to keep the space.

In addition, there is a problem in that it is necessary to manually mount another spacer or to provide another facility for mounting another spacer. Further, as described in Japanese Patent Application Laid-Open No. 60-38584, there is known a device in which a tile conveyor is devised to adjust the interval of the tiles conveyed on the conveyor. In addition, the structure and control of the conveyor are extremely complicated, and it is practically impossible to install an additional spacer mounting device for firing tiles in existing equipment that uses this type of conveyor. Was.

The problem to be solved by the present invention is that when a spacer for firing a tile is mounted on a group of tiles standing on an upright conveyor, the interval between the groups of tiles is adjusted. This is a point that another spacer is required, the operation is complicated, and further another device is required. In addition, if a transport conveyor that can adjust the interval between tile groups is adopted, the structure and control of the transport conveyor will be extremely complicated, and existing equipment that uses this type of transport conveyor will have space for roof tile firing. It is practically impossible to additionally install the mounting device;

It is understood that the roof interval adjustment control unit 93 described later reciprocates a relatively short distance on the base 66 between the previous process side and the next process side in synchronization with the driving speed of the upright conveyor 10. I can do it.

Then, the tile interval adjustment control section 93 will be described next. The tile interval adjustment control unit 93 adjusts the intervals between the tiles W in the tiles W arranged in a row before the tile firing spacers 8 are mounted on the tiles W group. A square cylinder 94 is supported on a cylinder base 91 provided on the upright transfer conveyor 10 on the upper surface of the base 66, and three rods 96 are mounted on the cylinder 94 toward the upright transfer conveyor 10. (See FIGS. 1 and 6).

A base 98 is provided on the rods 96, 96, 96 of the cylinder 94 on the side of the upright conveying conveyor 10.

Next to the base 98, the standing piece 10 is set on the next process side.
A base member 99 having a zero is provided. Base 9
8, two sets of rollers 102, 102 are mounted on both sides in the longitudinal direction. A support member 104 is fitted between the rollers 102 and 102 in the longitudinal direction of the base 98.

That is, the support member 104 is slidable with respect to the base 98 through the rollers 102 toward the next process side and the previous process side.

On the next process side of the support member 104, a pin 106 is provided.
Is directed to the next process side, and is stretched through the upright piece 100 of the base member 99.

A spring 108 is fitted around the pin 106, and has a function of returning to the original position by the elastic force of the spring 108 after the support member 104 slides to the pre-process side as described later. It is.

A pair of taper members 110 project from the lower surface of the support member 104 toward the spacer mounting mechanism 12 (see FIGS. 1 and 6).

Below the taper members 110, 110, a drive motor 112 is mounted on a cylinder base 91 via a mounting member, and a disk mounted on a rotating shaft 113 of the drive motor 112. An eccentric roller 116 is rotatably attached to a position 114 off the center.

The disk 114 is rotated between the taper members 110 by rotating the drive motor 112 with the center of the eccentric roller 116 as an eccentric shaft.
Are taper members 110 and 11 for rotating the disk 114.
It has a function of sliding the support member 104 by swinging 0 by the amount of eccentricity.

On the upper surface of the support member 104, a number of cylinders 118 corresponding to the number of the grooves 11 of the tile firing space 8 are generally directed toward the upright conveyor 10 while keeping a constant interval. It is arranged.

An adjusting rod 120 is slidably inserted through each of the plurality of cylinders 118, and an adjusting member 12 having a sharp end at the end of the adjusting rod 120 on the side of the upright conveyor 10 is provided.
2 are installed.

A spring 124 is fitted around the adjustment rod 120. The spring 124 adjusts the interval between the groups of tiles W. After the adjustment rod 120 slides so that the tile W is not damaged even if the tip of the adjustment member 122 abuts on the side surface of the tile W for some reason, The adjusting member 122 is provided to return to the original position by the force of 124.

In this embodiment, the direction of the adjusting rod 120 is slightly inclined to the next process side with respect to the upright conveying conveyor 10, but the inclination direction is slightly changed according to the shape and type of the tile. It is. Although illustration is omitted in this embodiment, a horizontal transport conveyor for transporting the tiles W one by one in a horizontal state is scheduled to be arranged on the pre-process side of the upright transport conveyor 10. Therefore, the cylinder 94 and the driving motor 112 constitute a composite moving means, and the tile interval adjustment control unit 93 has a function of performing a composite operation to equalize each interval of the tile W.

Next, the detailed operation of the present invention will be described. The roof tile W that has undergone steps such as molding, drying, and glazing is conveyed in a horizontal state toward the upright conveyance conveyor 10 by the horizontal conveyance conveyor in the previous process.

When the tile W reaches the pre-process side of the upright conveyor 10, the tile W is rotated by the intermittent drive of the rotating shaft 26 and is gradually raised up. It is scooped up and is raised between the four support rods 22, 24 in total with the other support rods 22, 24 adjacent to the rotation direction of the chains 18, 18 with the rotation of the chains 18, 18. See FIG. 1).

As described above, the tiles W are sequentially erected one by one on the upright conveyor 10 and, at the same time, the spacer mounting controller 70 is electrically controlled based on the data input in advance. It works by doing.

The body 72 of the spacer mounting control section 70, a pair of arms 74 and 76, and the holding member 78 pivot toward the spacer conveyor 14 based on a program, and the body 7
2, a set of arms 74 and 76 and a holding member 78 perform a so-called robot movement. Subsequently, at the take-out position of the spacer conveyor 14, each of the holding members 78 holds the tile firing space 8 previously mounted on the receiving table 48, and the spacer mounting control unit 70 returns to It turns toward the upright conveyor 10 and operates so that the tile firing spacer 8 is positioned above the tile W of the upright conveyor 10.

That is, the spacer mounting control unit 70
To the conveyor conveyor 14 side, and the body 72, the arm 74,
76 moves like a human upper limb,
Claw member 77 makes a movement in place of a human finger and picks up the tile firing spacer 8, and the spacer mounting control unit 70 again pivots toward the upright conveyor 10 (see FIG. 3). ), The held tile firing space 8 is mounted on the tile W by releasing the claw member 77.

In general, a single comb-shaped roof tile burning space
Since the roof 8 is configured so that about 10 roof tiles can be mounted at the same time, about 10 roof tiles W carried into the upright conveyor 10 from the previous process are sequentially erected by the support rods 22 and 24 described above. Since some time is required until a so-called time lag occurs, the spacer mounting control unit 70 is in a standby state for a while without being driven.

When about 10 tiles W are erected on the upright transport conveyor 10 while the spacer mounting control section 70 is on standby, the transport synchronization control section 53 operates first, and then the tile interval adjustment. The control unit 93 operates in the order of the spacer mounting control unit 70.

The operation of the transport synchronization control unit 53 will be described. When the spacer mounting control unit 70 enters the standby state on the upright transport conveyor 10 while holding the tile firing space 8, the basic state is as follows. The cylinder 84 attached to the upper surface of the table 66 is operated, the rod 86 is extended, and the swinging rod 82 swings downward.

When the swinging rod 82 swings downward, the guide groove 81 of the fitting member 88 provided at the end of the swinging rod 82
Of the chain 58 extending below the base 66.
It will mesh with the LA 57. At this time, the upright conveyor 10 is operating intermittently as described above, and the chain 58 is circulating through the rotating shaft 26 and the sprockets 56 and 62 toward the next process. Accordingly, when the chain 58 and the fitting member 88 mesh with each other, the base 66 is the same as the transport speed of the upright transport conveyor 10 through the fitting member 88 and the swinging rod 82 with the circulating movement of the chain 58. The guide rails 64 move at the speed toward the next process side.

When the base 66 is moved at the same speed as the transport speed of the upright transport conveyor 10, the tile spacing adjustment control unit 93 starts to operate. First, the cylinder 94 provided on the upper surface of the base 66 is operated, and the rods 96 and 9696 are gradually extended toward the upright conveyor 10 (FIG. 6).
See).

When the cylinder 94 is actuated, the base 98 approaches the upright conveyor 10 and is inserted through the cylindrical body 118 of the support member 104 and attached to the ends of a pair of adjacent adjustment rods 120. The respective adjustment members 122 approach toward the space between the adjacent tiles W standing on the upright conveyor 10 (see FIG. 1).

Then, at the same time as the rods 96, 96, 96 are gradually extended, the drive motor 112 provided on the cylinder base 91 is operated to rotate the disk 114. Since the eccentric roller 116 is rotated between the tape members 110, 110 provided on the lower surface of the support member 104, the eccentric roller 116 is fixed to the tape members 110, 110 by a certain short length. The contact will be repeated periodically.

The support member 104 to which the tape members 110 and 110 are attached is fitted to the group of rollers 102 provided on the upper surface of the base 98, so that the support member 104 is directed toward the pre-process side and the next process side. Reciprocate within a certain range.

Therefore, the taper members 110, 110 contacted by the eccentricity of the eccentric roller 116 are subjected to a force for moving the taper members 110, 110 toward the previous process side and the next process side. The adjusting rod 120 and the adjusting member 122 are adjacent to each other due to the gradual extension of the rods 96, 96, 96 of the cylinder 94 while reciprocating while reciprocating while relatively reciprocating with the elastic force of the spring 108 toward the pre-process side. It is inserted for a certain distance while abutting between the side surfaces of the roof tile W (see FIG. 1).

Thus, the driving of the adjusting rod 120 to advance to the upright conveyor 10 and the reciprocating drive of the upright conveyor 10 to the next process side and the previous process side are forcibly combined between the adjacent tiles W. As a result, the intervals between the adjacent tiles W are quickly adjusted to be equal, and a preparation for mounting the tile firing spacer 8 is prepared.

When the intervals between the tiles W are equal, the spacer mounting control section 70 starts operating again. The arms 74 and 76 of the spacer mounting control unit 70 in the standby state and the holding member 78 are operated again, and the tile firing space 8 held by the holding member 78 is mounted on the roof W.

Since the roof firing spacer 8 has a comb-like structure, it can be mounted on about 10 roof tiles W at the same time so that the roof tiles W do not fall down.

When the tile firing space 8 is mounted on the roof W, the holding member 78 of the mounting control unit 70 moves upward, and the body 7
2. The arms 74 and 76 rotate, and the holding member 78 faces the tile firing and conveying conveyor 14 side.

After the operation of the spacer mounting control unit 70, the base 6
The operation of the cylinder 84 on the cylinder 6 is released, and the rod 86 contracts by the action of the spring 87, so that the swinging rod 82 swings upward and the fitting member 88 is released from the chain 58.

When the fitting member 88 is released from the chain 58, the cylinder 90 mounted between the vertical columns 54, 54 on the pre-process side operates, and the rod 92 contracts (FIG. 1).
See).

When the rod 92 contracts, the base 66 moves on the guide rails 64, 64 toward the preceding process side, returns to the original position, and waits for the next operation.

At this time, the holding member 78 of the spacer mounting control unit 70 is located above the take-out position of the spacer transporting conveyor 14, and the spacer mounting control unit 70
Starts the next clamping operation of the tile firing space 8.

When all the spacers 8 for firing the tiles on the receiving tray 48 are taken out, the driving motor 42 drives the spacer transporting conveyor 14 to perform an intermittent operation, and the next receiving tray (FIG. 1 (see the dashed line in the rectangle)) to the take-out position.

On the other hand, the group of tiles W on which the tile firing space 8 is mounted is mounted on a firing cart, and is carried into the firing step in the next step while maintaining an ideal interval between the group of tiles W.

[0085]

Since the present invention is constructed as described above, when a tile firing spacer is mounted on a group of tiles standing on an upright conveyor, another space adjusting space is required. Since no spacer is required, the operation for mounting the tile firing spacer is not complicated, and no separate device is required. Also,
The spacer is controlled intermittently by the upright conveyor by reciprocatingly driving the spacer mounting control unit and the tile interval adjustment control unit while synchronizing with the intermittent drive of the upright conveyor via the operation of the conveyance synchronization control unit. The tile groups can be arranged in order and the intervals between the tiles can be adjusted equally, and the tile firing spacer can be mounted on the roof group by the spacer mounting mechanism so that the tile groups do not fall down. Furthermore, since the spacer mounting mechanism is provided beside the upright conveyor, and the tile mounting mechanism is provided in the spacer mounting mechanism, the upright conveyor has a function of adjusting the tile interval. There is no need to provide. Therefore, it is possible to avoid complication of the structure and control of the upright conveyor, and it is possible to additionally install a spacer mounting device for roof tile firing on existing equipment.
