Description

[Detailed description of the invention] (Technical field of the invention) This invention relates to a gripping device for tile bases that continuously supplies tile bases to a glazing process (prior art) As a prior art of this type, the Utility Model Publication No. 54-1481 There is an idea described in the No.

This example consists of a dogleg-shaped rod with a support hole at the upper end so that it can be hung on a conveyor for glazing, and a holding plate at the lower end, and a guide pin fixed at right angles to the dogleg-shaped rod at the bent part of the dogleg. It consists of an L-shaped rod that loosely fits into a guide pin at one end and a holding plate is provided at the other end, and a part of the conveyor is provided with a U-shaped curved section that descends once and then rises, and the guide is attached to the curved section. It is constructed so that a rail is provided and a guide pin slides on the guide rail.

(Problems with the Prior Art) The conventional example described above has the advantage of automatically grasping the tile blank and supplying it to the glazing process, but has the following problems.

Only the dogleg-shaped rod side slides on the guide rail of the conveyor, and the L-shaped rod side is simply suspended by its own weight using the guide pin as a fulcrum.

In other words, the dogleg-shaped rod gradually changes from a vertical state to a horizontal state along the guide rail and grips the tile base, while the L-shaped rod is simply suspended by its own weight using the guide pin as a fulcrum, as mentioned above. It is merely lowered and its posture is not forcibly changed by the guide rail.

For this reason, the L-shaped rod cannot be tilted from a vertical state due to its own weight in a direction that widens the distance between it and the dogleg-shaped rod, and it is possible to avoid the phenomenon of not gripping the tile base when the opening angle is insufficient. What happened?

In particular, as mentioned above, the L-shaped rod is simply suspended from a guide pin provided on one side, so when it follows the conveyor and travels at a speed of about 24 m/min, it moves forward and backward in the direction of travel. As a result, the distance between the tile rod and the dogleg rod becomes narrow or too wide, resulting in the problem that the tile base cannot be gripped.

Furthermore, since it is not possible to completely prevent glaze from adhering to the base of the guide pin during the transportation of the tile base during the glazing process, the adhered glaze may be removed by the time the guide pin goes through the transportation process and reaches the tile base clamping position again. Once it dries, it is fixed to the fulcrum part and the L-shaped rod and dogleg-shaped rod move together.

As a result, the guide pin is not easily opened and closed using the guide pin as a fulcrum, and the gap between the L-shaped rod and the dogleg-shaped rod reaches the clamping position in a narrow or wide state, resulting in the defect that the tile base cannot be gripped reliably. Ta.

Furthermore, in the gripping hanger in this example, the guide pin simply slides on the guide rail of the conveyor, so if glaze adheres to the guide rail, the hanger will not run smoothly and will simply become a fulcrum. There was also the problem that the L-shaped rods that were hung on the roof swung violently in the front-back direction and were unable to grip the tile base.

(Technical Problem of the Invention) The purpose of this invention is to eliminate mistakes in gripping the tile base during the process of transporting the tile base.

Another object of this invention is to perform the clamping action stably and reliably by forcibly opening and closing the clamping mechanism for tile base material.

(Technical means of the invention) The basic structure of this invention is an approximately arc-shaped upper clamp with a support hole at the upper end and a presser plate for the tile base at the lower end, and a presser rod with a gap. A support piece is provided, and a substantially C-shaped clamping piece that bulges outward is fixed to the lower side of one side of the presser rod support piece, and the lower end of the clamping piece is fixed in a direction perpendicular to the clamping piece. A lower clamp is provided with a presser plate, and the lower clamp is provided in the gap between the presser rod support pieces with the support hole facing upward, the presser plate facing downward, and provided on one side of the presser rod support piece. An upper clamp is rotatably provided in the gap via a fulcrum pin by inserting it opposite the presser plate, and the upper clamp is inserted in the front and back of the presser rod support piece in a direction perpendicular to the upper clamp. A hanger for tile base material is provided with a pair of guide pins each rotatably provided,
On the other hand, a conveyor mechanism is installed in a part of the conveyor for glaze painting, which is equipped with a guide rail that curves downward in a substantially arc shape and then continues to rise. A pair of guide pins at the front and rear of the tile base hanger are rotatably provided on a guide rail in a direction perpendicular to the hanger.

(effect of invention) The effect of this idea will be explained.

A small pin is inserted into a support hole provided in the upper clamp of the gripping hanger through an appropriate metal fitting on the lower side of the conveyor, and a large number of the hangers are freely suspended at regular intervals.

Therefore, a large number of hangers are provided so as to be swingable relative to the conveyor.

Therefore, the conveyor is driven at a constant speed (generally at a speed of about 24 m/min), so that the conveyor runs at a constant speed.

As the conveyor runs, this hanger moves to the position of the tile base in a horizontal position, which is waiting for glaze coating. The upper clamp and the lower clamp, which are gradually positioned in a vertical position while being guided by a guide rail, are tilted toward the running direction of the conveyor, and are then brought into a horizontal position at the base of the running side of the guide rail. At the same time, the upper clamp and the lower clamp rotate around the fulcrum pin, and the gap between both clamps opens to the maximum. The upper and lower clamps sandwich the upper and lower clamps, and the tile base is transferred to the glazing process as it is.

In this case, the two guide pins installed at the front and rear of the upper clamp rotate the hanger along the guide rail attached to the conveyor, so both the upper and lower clamps move stably and reliably and smoothly. It goes without saying that you should.

(Embodiments of the invention) Details of embodiments of the invention will be described below with reference to the accompanying drawings.

This invention basically consists of a conveyor 10 and a gripping hanger 32 for tile material vertically installed on the conveyor.
It consists of.

Most of the conveyor 10 is horizontal, but as shown in FIG. 1, a portion of the conveyor 10 is curved downward into an arc.

Two sets of arc-shaped guide trays 34 are provided below the curved portion of the conveyor 10 along the curved portion in the length direction of the conveyor.

This one set of guide rails 34 is on the inside, and the other one is on the inside.
The set of guide rails 34 are arranged on the outside.
In other words, the two sets of guide rails 34 are provided separately into a wide gauge and a narrow gauge.

These two sets of guide rails 34 support a pair of front and rear guide pins 30a and 30b of different lengths of a grip hanger 32, which will be described later (see FIG. 2).

To explain the gripping hanger 32 of this embodiment, the hanger 32 includes the upper clamp 18,
Lower clamp 28, presser rod support piece 22, fulcrum pin 21, and two long and short guide pins 30a, 3
It consists of 0b.

The upper clamp 18 has a metal fitting 40 provided at its upper end below the conveyor 10 shown in FIG.
A support hole 12 is provided in the support hole so that the tile material M can be suspended through a small pin, and a relatively small plate-shaped holding plate 14 for the tile base material M is provided at the lower end, and the support plate 14 is arranged in a substantially circular shape toward the outside. It consists of a presser rod 16 which is curved in an arc shape.

The presser rod support piece 22 has a gap 2 that is slightly larger than the thickness of the presser rod 16 of the upper clamp 18.
0, and is made up of two elongated rectangular metal plates in the drawing, but it is not limited to what is shown in the drawing, and although it is not shown, it can be made into a single metal plate by pressing. The material may be punched out to provide a long and narrow gap, or it may be made of plastic as long as it has a certain level of strength; in principle, the material does not matter.

What is required is a configuration that allows the upper clamp 18 to rotate freely and the guide pins 30a, 30, which will be described later.
b is configured to be rotatably mounted.

Then, one side (left side in the drawing) of the presser rod support piece 22 is bulged downward and outward.
A letter-shaped clamping piece 24 is fixed to the clamping piece 24.
Another pressing plate 26 is provided on the lower end side of the holding plate 26 in a direction perpendicular to the clamping piece 24 and is curved outward in an arc shape.

On the other hand, the support hole 12 of the upper clamp 18 is provided upwardly in the approximate center of the gap 20 of the presser rod support piece 22, and the presser plate 14 thereof is provided below and on one side of the presser rod support piece 22. lower clamp 2
The upper clamp 18 is opposed to the holding plate 26 of 8.
is inserted and rotatably provided by a fulcrum pin 21.

Then, on both sides of the upper clamp 18, a pair of guide pins 30 (long and short) in front and back of the presser rod support piece 22 are arranged in a direction perpendicular to the upper clamp 18.
In this embodiment, the guide pins 30a and 30b are short on one side and long on the other side, but the guide pins 30a and 30b may be configured with opposite lengths. The lengths of the relays 34 may be the same in the front and rear.

The configuration of the grip hanger 32 constituting this device is disclosed above.

Therefore, the combination structure of the hanger 32 and the conveyance mechanism will be explained.
Two sets of guide rails 34 are curved downward in a substantially arc shape on a part of the lower side and continue to rise.
A gripping hanger 32 for the tile base material M is provided in a direction perpendicular to the longitudinal direction of these guide rails 34.
A pair of front and rear guide pins 30a, 30b are rotatably provided on a guide rail 34. Furthermore, to explain the combination of the tile base hanger 32 and the guide rail 34, as shown in FIG. 1, two sets of the guide rail 34 are installed side by side at a constant interval.

Then, the tile base hanger 32 is positioned between these two sets of guide rails 34, and the upper clamp 18 and lower clamp 28 of the hanger 32 are rotated via the fulcrum pin 21 in the space between the two sets of guide rails 34. The hanger 32 for the tile base is installed in a direction perpendicular to the longitudinal direction of the guide rail 34 so as to be movable.
A pair of front and rear guide pins 30a, 30b are rotatably spanned over a guide rail 34.

In FIG. 1, another conveyor 23 is provided below the conveyor 10, and is for supplying the tile blank M to the tile blank holding hanger 32 of the conveyor 10.

This conveyor 23 moves toward the right side in the drawing.

At the right end of the conveyor 23 is a rotary tile raising machine 33.
This vertical raising machine 33 is provided with a plurality of receiving forks 35 for receiving the tile blank M.

(Effects of the invention) Since this invention has the above configuration, it has the following advantages.

(1) The upper and lower clamps of the gripping hanger are rotated on guide rails attached to the conveyor by two guide pins at different positions from the fulcrum, so both clamps are attached to the two guide pins. It is forced to open and close at a predetermined position due to the relative positional relationship of the guide pins.

Therefore, unlike the conventional example, there is no uncertainty in the opening/closing action between the two, and the opening/closing operation is stable and reliable, so there is no possibility of erroneous clamping of the tile base.

(2) In this design, both the upper and lower clamps are controlled to run, open and close by two rotating guide pins, so unlike the conventional example, the lower clamp in particular swings back and forth in the running direction. Since there is no problem, you can securely sandwich the tile base.

(3) Both the front and rear guide pins are rotatable, so the gripping hanger can run smoothly on the guide rail, and the constant rotation of the guide pin prevents glaze from adhering to the base of the guide pin. It offers difficult advantages.
