Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mounting machine for mounting comb spacers for firing onto rows of roof tiles loaded on a truck (kiln car).

An object of the present invention is to automatically mechanize the work of attaching tooth spacers to rows of tiles, thereby making the tile manufacturing line unmanned and improving the quality of the tiles.

Currently, the entire process of tile manufacturing, from kneading the clay to shipping the finished product, is largely automated.
We are doing mass production.

However, the work of attaching the comb-tooth spacers to tiles is still a manual process.

This is because, as shown in FIG.
This is because it is extremely difficult to mechanize accurately attaching roof tiles to the top of tiles arranged vertically at intervals of about CrIL without damaging them.

The installation of comb-tooth spacers is essential in the process of loading roof tiles onto carts, drying them, and firing them.

Comb tooth spacers are attached to every 6 to 8 tiles, and although the installation process is simple to do manually, it is a busy job that requires vigilance, and automated mechanization is desperately needed. .

Additionally, in the production of roof tiles, it has been empirically known that the fewer times human hands touch the roof tiles, the better the quality of the roof tiles will be. It's long awaited.

Therefore, the ultimate purpose of this invention is to create a substantially vertical rectangular cylindrical magazine in which comb spacers are stacked and stored in a substantially vertical direction in the same posture, and a magazine that is connected from the outlet at the bottom end of the machining machine to the comb spacers at the bottom end. A take-out mechanism that sequentially ejects the spacers one by one and feeds them into the guide groove in a fixed posture; A transfer mechanism that sends the comb-tooth spacers in the guide groove to a specified position in the guide groove; A comb tooth for dead firing, which is composed of a chuck device that can be raised and lowered to grab the comb tooth spacer that has reached it, and a reciprocating device that reciprocates the chuck device from the specified position to a position where the comb tooth spacer is attached to the tile. Using a spacer mounting machine or the entire configuration of the above mounting machine as the main part, the comb-tooth spacer mounting position of the chuck device is alternately shifted by an amount equivalent to the thickness of the comb-tooth spacer for each reciprocation of the chuck device. It is an object of the present invention to provide a mounting machine for a comb-tooth spacer for dead firing, which is configured to include a mounting position changing mechanism.

Next, the present invention will be explained with reference to illustrated embodiments.

1 and 2 show a plan view and a side view of a comb-tooth spacer mounting machine for dead firing, which is an embodiment of the present invention.

In the figure, 1 is a conveyor forming an automated tile manufacturing line.

The tiles 2 are stacked vertically on the conveyor 1, oriented perpendicular to the forward direction of the conveyor 1 (direction of arrow A), and stacked in a vertical line with an interval of about 2 cm to 5 cfrL from front to back. Ru.

In the figure, reference numeral 3 denotes an accompanying conveyor that holds the upper end portions of tiles 2 loaded on the conveyor 1.

This accompanying conveyor 3 moves synchronously with the conveyor 1 at the same speed.

The accompanying conveyor 3 has spacers 3a interposed between the front and rear tiles 2, 2, which are stood upright on the conveyor 1, at regular intervals (FIG. 1).

The accompanying conveyor 3 holds the upper part of the tile 2 on the conveyor 1 until it is supported by the interlocking spacer 4.

After the support of the roof tile 2 is replaced by a comb-tooth spacer, it is installed in a line configuration that separates from the roof tile 2.

As an example of the shape is shown in FIG. 6, the comb-tooth spacer 4 has a comb-tooth shape punched out of an elongated heat-resistant flat steel plate, and is generally manufactured as a press-formed product or a cast product.

In the mounting machine, the comb tooth spacer 4 is placed flat in a rectangular cylindrical magazine 5 that stands approximately vertically, and is placed vertically in order with the direction of the comb teeth aligned in the direction shown in FIG. 1 (direction of ejection). They are stacked and stored.

As shown in FIG. 1, the rectangular cylindrical magazine 5 has a rectangular cylindrical shape with a cross section that is approximately the same shape and size as the comb-tooth spacer 4, and has at least two comb-tooth spacers 4 at a time.
In order to have the capacity to store approximately 2,200 sheets per hour (approximately 2 m in magazine length), the chute 5' is designed with the upper part inclined at an angle θ which is greater than the angle of repose of the spacer 4. It consists of

In other words, if the cylindrical magazine 5 is simply set vertically, there is a problem in relation to the height of the ceiling of the building, and the capacity of the magazine 5 is limited, and the loading weight of the stored comb spacer 4 is proportionally This is because as a result of the increase in size, it becomes extremely difficult to take out.

In the figure, 6 indicates the comb spacer 4 stored in the magazine 5.
This is a proximity switch 6 that monitors the remaining amount of .

Next, a mechanism for taking out the revolving spacers 4 one by one from the magazine 5 and sending them into the guide groove γ will be explained.

A table 8 is fixed horizontally on the machine frame 07, and the magazine 5 is vertically installed at a position near the end of the table 8 (close to the left end in FIG. 3).

The magazine 5 has an ejection opening 9 with a gap slightly larger than the thickness of the toothed spacer 4 on the front side of the contact portion with the table 8 (on the left side in FIG. 3).

Further, on the rear side (right side in FIG. 3), there is an ejector plate opening 10 with a gap slightly larger than the thickness of the ejector plate 11.

The thickness of the protruding plate 11 is smaller than the thickness of the toothed spacer 4.

The ejector plate 11 is installed on the table 8 so as to be in contact with the upper surface of the table 8 and to move back and forth while being guided by guide blocks 12 and 12 on its two parallel side edges.

Guide blocks 12, 12 are fixed on table 8.

A pneumatic cylinder 14 (a hydraulic cylinder or a screw feeding device can also be used) drives the ejector plate 11.

) is fixed on the machine frame 07 with a bracket 13° 13, and its piston rod 14a and the above-mentioned protruding plate 1
1 by a plate holder 15.

Therefore, due to the forward stroke of the pneumatic cylinder 14, that is, the forward stroke of the ejecting plate 11, only one of the lowest comb-tooth spacers 4 stored in the magazine 5 is moved out of the ejecting port 9. Being pushed out.

In the figure, reference numeral 16 denotes a limit switch installed below the table 8 to check whether or not the comb spacer 4 has been pushed out.

In table 8, in front of magazine 5 (UIJ (83
The end of the (left side in the figure) is formed into a slope 17 that descends steeply, and a guide plate 18 forming a symmetrical slope is installed parallel to the end, resulting in a comb tooth whose cross section is approximately square-shaped. A spacer fall port B is formed.

The lower end exit of the comb-tooth spacer falling port B is located in the guide groove 7 directly below.
The system is configured to contact the following.

Therefore, after the comb-tooth spacer 4 pushed out of the ejection port 9 of the magazine 5 by the ejection plate 11 reaches the spacer drop port B, the front edge of the comb-tooth spacer slides down along the slope of the guide plate 18. In other words, the comb teeth necessarily fall into the guide groove 7 with the comb teeth facing downward and are accommodated therein.

23 in the figure is a proximity switch 23 for confirming that the comb spacer 4 has reached the guide groove 7.

In order to make it easy and reliable for the front edge of the teeth to slide down the inclined surface of the guide plate 18, the guide plate 18 has a spring 19 at the base end of the support arm 18a18a. The guide plate 18 is mounted on the table 8 in a cantilevered manner, and the guide plate 18 itself is suspended by a tension spring 20.

In other words, the guide plate 18 vibrates effectively all the time due to vibrations generated in the mounting machine, and therefore, when the front edge of the comb spacer 4 comes into contact with it, its sliding down is effectively caused by the vibration. It is promoted.

Next, the comb-tooth spacer 4 falls into the guide groove 7 and is accommodated.
A transport mechanism for transporting the material to a position where it is grabbed by the chuck device will be explained.

As shown in FIG. 3, the guide groove 7 has two angles 21,
21 are arranged substantially parallel back to back and are fixed on the base plate 22 with a gap (groove width) slightly larger than the thickness of the comb spacer 4.

The guide groove 7 is installed at a position directly below the reciprocation of the chuck device described below and has a length that allows the chuck device to grip the comb-tooth spacer 4.

The relationship between the depth of the guide groove 7 and the height of the comb spacer 4 is as follows:
As shown in FIG. 4, the height relationship is such that the toothed spacer 4 protrudes by a size that allows it to be easily grasped by the chuck device.

In the figure, reference numeral 24 denotes a button that feeds the comb-tooth spacer 4 that has fallen into the guide groove γ to a position where it can be gripped by the chuck device.

As shown in FIG. 3, the bushing 24 has a thin plate-shaped suppressing portion 24a that has approximately the same thickness as the toothed spacer 4 and is always located in the guide groove 7.

As shown in FIG. 1, the bushing 24 is attached to the tip of a long feed shaft 25 arranged parallel to the guide groove 7.

The feed shaft 25 is slidably supported by a sliding bearing 26 fixed on the base plate 22.

The feed shaft 25 has a length greater than or equal to the transfer distance of the toothed spacer 4.

The base end of the feed shaft 225 is connected to the piston rod 28 of the pneumatic cylinder 28 with a long stroke by the connecting block 27.
It is connected to a.

The pneumatic cylinder 28 is fixed on the base plate 22 in a position parallel to the guide groove 7 .

The pneumatic cylinder 28 has an effective stroke equal to <the transport distance of the toothed spacer 4.

Therefore, when it is confirmed by the limit switch 16 and the proximity switch 23 that one comb spacer 4 has been ejected from the magazine 5 and has reached the guide groove 7, the forward stroke of the pneumatic cylinder 28 is started by that signal. do.

As a result, the comb spacer 4 in the guide groove 7 is pressed by the pressing portion 24a of the bushing 24 attached to the feed shaft 25.
It is pushed toward a position where it is grabbed by a chuck device.

When the comb spacer 4 reaches the specified position where it is gripped by the chuck device, the limit switch 29 issues a confirmation signal.

The limit switch 29 is installed on a stand 30 that stands upright at the tip of the guide groove 7, as shown in FIGS. 1 and 4.

The limit switch 29 is configured to issue a confirmation signal when the front end of the comb spacer 4 abuts against the input arm 29a and is moved by a certain stroke.

Reference numeral 31 in FIG. 4 is a stopper for the comb-tooth spacer 4 installed at the tip of the guide groove 7.

When the limit switch 29 issues a confirmation signal, the pneumatic cylinder 28 stops its forward stroke and then starts its backward stroke, moving the pusher 24 to its initial position (the position in FIG. 1).
Return to and stop.

Next, a chuck device that grips the comb-tooth spacer 4 sent to a prescribed position in the guide groove 7 and a reciprocating device that reciprocates the chuck device from the prescribed position to a position where the comb-tooth spacer is attached to the tile will be described.

Two guide rods 32, 32 are arranged at right angles to the conveyor 1 for transporting the tiles 2 and the guide groove 7 for transporting the comb-tooth spacers 4, and their ends are connected to a frame 33.
, 33, and are screwed in and fixed with nuts 35, so that they are installed horizontally and in parallel.

The guide sleeves 37, 37 of the carriage 36 are fitted onto the guide rods 32, 32, and the guide rods 32, 3
It is possible to freely move back and forth along 2.

A chuck device 38 is installed below the carriage 36 so as to face downward.

The base plate 39 of the chuck device 38 is connected at its center to a piston rod 40a of a vertical pneumatic cylinder 40 fixed to the carriage 36 (FIG. 6).

Guide rods 41, 4 standing upright from the base plate 39
1 of the carriage 36 is slidably passed through the idle sleeve 42,42.

Therefore, the horizontal base plate 39 is connected to the pneumatic cylinder 40
vertically raised and lowered by

Note that the means for raising and lowering the base plate 39 is not limited to the method using the pneumatic cylinder 40.

For example, a rack-and-pinion type electric motor drive or a hydraulic motor drive raising and lowering method may be adopted.

A slide plate 48 is installed parallel to the base plate 39 on shafts 47, 47 supported by bearings 46, 46 on the lower surface of the base plate 39, and its position can be adjusted in the left-right direction by turning an adjustment nut 49. There is.

A chuck plate 50 is installed below and parallel to the slide plate 48.

The chuck plate 50 is attached to the slide plate 4 by a vertical guide pin 51 and a compression coil spring 52.
8, and is installed in a resilient state that allows it to move to some extent in the vertical direction.

A pair of chucks 5 are provided on the lower surface of the chuck plate 50.
3 and 53 are installed in a symmetrical arrangement.

The chuck device 53 is based on the principle of a so-called four-bar parallel link mechanism, in which an upper movable pin 54 is connected to a piston rod 5 of a pneumatic cylinder 56 via a knuckle joint 55.
It is connected to 6a.

The pneumatic cylinder 56 is fixed to the chuck plate 50,
It is installed vertically downward.

The lower fixing pin 57 has both ends attached to the brackets 1-58.
5B, it is supported in a fixed position.

Link members 59 and 6 connected by fixing pins 57
The comb-tooth spacer 4 is sandwiched and gripped by the fingers 59a and 60a at 0.

In other words, as the piston rod 56a of the pneumatic cylinder 56 moves downward, the pair of fingers 592
．． 60a closes and holds the comb spacer 4 between them.

Then, the pair of fingers 5592.60a opens due to the previous upward stroke of the piston rod 56a, releasing the comb spacer 4.

The reciprocating stroke of the piston rod 56a is controlled by a limit switch 61°62 (Fig. 2) installed on the bracket 58.
Detected by

In the figure, 45 is a pneumatic cylinder with a long stroke for reciprocating the carriage 36.

As shown in FIGS. 1 and 2, this pneumatic cylinder 45 is swingably installed at its intermediate portion on a bracket 43 on the pedestal 33 by means of a trunnion shaft 44. As shown in FIGS.

The tip of the piston rod 45a is coupled to a pressing plate 63 of the reciprocating table 36.

In the figure, 64 and 65 are limit switches that detect the reciprocating stroke of the pneumatic cylinder 45.

Note that the movement of the carriage 36 is not limited to the method using the pneumatic cylinder 45 described above.

For example, a rack-and-pinion electric motor drive system or a hydraulic motor drive system may also be adopted.

Therefore, when the limit switch 29 detects that the toothed spacer 4 has reached the specified position where it is gripped by the chuck device 38, the return stroke of the pneumatic cylinder 45 starts in response to the detection signal, and the reciprocating table 36 is moved to the second position. Move to the right side of the diagram.

When the carriage 336 generates a detection signal to the right limit switch 65, that is, when it detects that the chuck device 38 has just reached the specified position to grip the comb spacer 4 in the guide groove I, the detection signal causes the empty The return stroke of the pressure cylinder 45 is accompanied.

Subsequently, the pneumatic cylinder 40 of the chuck device 38 starts a downward forward stroke, and the chuck device 38 descends toward the comb-tooth spacer 4 directly below. , and comes into contact with the upper edge of the comb-tooth spacer 4 located in the guide groove 7 directly below (FIG. 6).

Note that the impact force and slight stroke error when the bracket 58 hits the comb-tooth spacer 4 are caused by the coil spring 52.
It is elastically absorbed by the contraction of .

When the forward stroke of the pneumatic cylinder 40 is completed, the pneumatic cylinder 56 of the chuck 53 then starts a downward forward stroke, and the chuck 53 based on the four-bar parallel link mechanism principle has a pair of fingers 59a.

Close 60a and hold the comb spacer 4.

The forward stroke of the pneumatic cylinder 56 is controlled by the limit switch 61 (
(Fig. 2) ends at the position where the signal is emitted.

As a result, the tooth spacer 4 is supported at two points by the pair of left and right clamps 53, 53, as shown in FIG.

Next, upon receiving the detection signal from the limit switch 61,
The pneumatic cylinder 40 of the chuck device 38 starts an upward return stroke, and the comb spacer 4 gripped by the chuck 53 is
Pull it out from the guide groove 7 and lift it up.

When the hydraulic cylinder 40 completes the full backward stroke, the hydraulic cylinder 45 then starts the forward stroke to the left in FIG.
Move 6.

When the reciprocating table 336 reaches the position where the left limit switch 64 generates a signal, that is, the position where the chuck device 38 and the tooth spacer 4 are attached to the upper part of the tile 2..., the detection signal causes the pneumatic cylinder to 45 is stopped.

Subsequently, the chuck device 38 is lowered by the downward stroke of the pneumatic cylinder 40 of the chuck device 38, and as shown in FIG. Each comb tooth is attached to the tiles 2 standing upright on the conveyor 1 which has stopped running in such a manner that each comb tooth fits between the adjacent tiles 2, 2....

The forward stroke of the pneumatic cylinder 40 completes the installation of the comb spacer 4.

Subsequently, due to the upward return stroke of the pneumatic cylinder 56, the chuck 53 opens the pair of fingers 593.60a and releases the toothed spacer 4.

When the limit switch 62 generates a signal, the pneumatic cylinder 40 of the chuck device 38 starts an upward return stroke in response to the signal, and the chuck device 38 is raised and ready to wait for the next signal input.

Note that the number of roof tiles 2... conveyed by the conveyor 1 is counted by a counter.

Then, this counting signal is determined according to the number of teeth of the comb-tooth spacer 4. For example, in the case of FIG. Used as a control signal for intermittent driving.

Comb tooth spacer 4゜4 that moves back and forth in the running direction of the conveyor 1
At both ends, wrap and add one tile so that it is held in common.

That is, the conveyor 1 is stopped by a count signal from a counter, and starts running again after a certain period of time (approximately 20 seconds to 40 seconds) set by a timer.

Next, when attaching the comb-tooth spacer 4 to the top of the tile 2..., one tile is held in common at both ends of the comb-tooth spacers 4, which are adjacent to each other in the running direction of the conveyor 1. In order to wrap and add without any trouble, the following measures are adopted.

The first method is to attach the comb-tooth spacer 4 to the tile 2, as shown in FIG. ...
The conveyor 1 is installed at a certain angle with respect to the traveling direction of the conveyor 1, that is, the traveling direction of the conveyor 1.

Specifically, a configuration in which the guide rod 32, 32 is tilted at a certain angle with respect to the traveling direction of the conveyor 1, a configuration in which the guide groove I and the chucks 53, 53 are tilted at a certain angle, or the entire chuck device 38 is required. Means a method such as twisting (rotating) a certain angle according to the

The second method is to alternately shift the position at which the chuck device 38 and the comb-tooth spacers 4 are attached to the roof tiles 2 by the thickness of the comb-tooth spacers 4 one by one, and alternately one by one in a staggered manner. The structure is such that it can be worn.

Specifically, as shown by the two-dot chain line in Figures 1 and 2,
A guide sleeve 6 is attached to a predetermined position of the guide rods 32, 32.
7 is fixed, an upright bracket 68 is attached to the guide sleeve 6T, and a pneumatic cylinder 69 is installed vertically downward on the front surface of the bracket 68.

On the other hand, a ruler plate 71 having a thickness equal to or slightly larger than the tooth spacer 4 is attached to the piston rod 9a of the pneumatic cylinder 69, and the ruler plate 71 is attached to the bracket 68.
It is configured to move up and down along the front guide 72, and therefore,
Once every two reciprocations of the carriage 36, the pneumatic cylinder 6
When the ruler plate 71 is lowered at step 9, the normal stop position of the carriage 36 changes by the thickness of the ruler plate T1, and the mounting position changing mechanism is configured such that the mounting positions of the tooth spacers 4 are arranged in a staggered manner. .

Reference numeral 70 in FIG. 1 is a connecting beam that connects the left and right guide sleeves 67, 67.

Next, the chuck 53 is not limited to the one based on the illustrated four-bar parallel link mechanism principle.
