Description

[Detailed description of the invention] The present invention relates to an automatic tile size measuring and sorting machine.

Conventional tile dimensional measurements and selection based on the measurements are generally performed by sampling inspection.

In other words, select a number of tiles arbitrarily from among the tiles sintered for each fixed loft, measure the width with a caliper, etc., and if the width is within the specified standard dimension, the loft is considered to have passed the standard. If it was outside the dimensions, the method used was to measure all four pieces individually and sort them out.

However, this inspection method has the following drawbacks.

(+,) Since not all inspections are carried out, even if a randomly selected inspection happens to pass, there is no guarantee that all lofts that pass the inspection will be within the standard dimensions. For this reason, during the on-site construction stage, tiles with non-standard dimensions are often discovered.
This had to be removed each time the work was carried out, resulting in a problem of poor construction efficiency.

(2) Even if an arbitrary selection test is performed, the test efficiency is low because it is done manually using a vernier caliper. In particular, for tiles that are out of standard dimensions, the dimensions of all tiles must be measured using a caliper, which has the disadvantage of making the drilling process more difficult and inefficient.

This invention was made with an eye on the conventional intermediary points, and its purpose is to position the tiles that are sequentially transferred and to detect the width dimension of the tiles using an analog sensor. If the width dimension read is outside the preset standard dimension, remove the blockage by 1.
Automatic tile dimensions)
I'll give you another chance! (There is.

The present invention will be explained below based on actual lung examples shown in FIGS. 1 to 3.

FIG. 1 is a sectional view taken along the line Tl--Tl of FIG.

In the figure, 1 is a tile, 2 is a belt conveyor that transports the tile 1 in the direction of the arrow a, and 2 is a belt conveyor synchronization belt that extends along the belt conveyor 2 to the machine frame F.

This bell) V is a guide bell) 7 that is stretched between the first pulley 5 and second pulley 6 fixed to the rotating shafts 3 and 4 attached to the machine frame F, and the alignment plate 5 provided along the belt conveyor 2. The third pulley 8 is fixed to the rotating shaft 3 of the first pulley 5 and is driven by a belt 9.

The bell) V is synchronized with the belt conveyor 2, is driven in the direction of the arrow Na at the same speed as the conveyor 2, and is transported on the belt conveyor 2 by sliding on the alignment plate q. One side surface 1& of the tile 1 is received and the tile position is defined while guiding this.

What about M? It is a 1159 rod and is installed on the opposite side of the belt conveyor tuning bell (V) across the belt conveyor 2. That is, this measuring rod M is rotatably supported by a rotary shaft 10 attached to a bearing of the machine frame F, so that it can be rotated in the direction of the belt conveyor synchronizing bell), and in the direction of the arrow, that is, as shown in FIG. For example, the upper end of the measuring rod M [1
7 until it hits the analog sensor 5.
It is installed by being biased by a spring 11 attached to the lunge 5.

Reference numeral 12 denotes a contact roller installed at the lower end of the measuring rod M, which is in contact with the other side surface 1b of the tile 1 that is transported on the belt conveyor 2 with its position specified by the belt conveyor tuning bell (V). Then, it rotates on the side surface 1b.

S is an analog sensor attached to the flange 13 of the machine frame F facing the measuring rod M. This sensor S is
It has a function of reading the distance t from the upper end of the measuring rod M as it rotates, and therefore the width W of the tile 1, based on the strength of the electric signal, and outputting this to an electronic control device (not shown). ing.

The electronic control device referred to here has the standard dimensions of the tile 1, that is, the standard dimension value W and its tolerance range, stored in advance, and is compared with the width dimension W according to the input electric signal, and this is the standard dimension. When it is outside, the signal is output to a bush-out cylinder (not shown). Then, the push-out cylinder that receives the signal removes the tile 1 from the belt conveyor 2.

Note that C is a tile count switch that counts tiles 1.

Next, the effect will be explained.

When the tile 1 is transferred by the belt conveyor 2, the belt conveyor synchronizing bell (V) sends the tile 1 in the direction of the arrow a while receiving and positioning the tile 1 by one side surface 1a.

Then, the contact roller 12 of the measuring rod M rides on the other side surface 1b of the tile 1 and rotates thereon.

At this time, the measuring rod M rotates in the direction indicated by the arrow around the rotating shaft 10 by an amount corresponding to the width W of the tile 1,
The analog sensor A facing this reads the distance t from the measuring rod M, that is, the width W of the tile 1, based on the strength of the electric signal, and outputs it to the electronic control device. Then, the electronic control device compares the input width dimension W with the standard dimension of the tile 1 stored in advance. If the size is outside the standard size, the push-out sill inputs the signal and removes the corresponding tile 1 from the belt conveyor 2.

In the above embodiment, the rotation of the measuring rod M - [(10
By increasing the length from the contact roller 12 to the contact roller 12, it is possible to measure and sort with sufficient accuracy even widths of 100 to 300 mm.

Further, in the above embodiment, the measuring rod M is configured to rotate around the rotating shaft 10, but the measuring rod may be configured to be translated in a conventional manner.

When measuring the width dimension W of the tile 1, for example, transfer it to another belt conveyor that intersects with the belt conveyor 2,
This may be carried out using the same measuring and sorting machine as in the above embodiment.

As explained above, the tile size measuring and sorting machine according to the present invention includes a belt conveyor for transporting tiles, a belt conveyor along the belt conveyor, and a v A belt conveyor synchronizing belt that defines the tile position while guiding, and a contact roller disposed on the opposite side of the belt conveyor, movable in the direction of the belt, and provided at the lower end of the belt conveyor. A spring-loaded measuring rod is installed to face the upper end of the measuring rod so that it can rotate on the other side of the tile, and the width of the tile is determined by the distance from the upper end. Consisting of an analog sensor that reads whether the width of the tile is within the standard size or other than the standard size, and a push-out cylinder that receives a signal that the read width of the tile is outside the standard size and removes the tile from the belt conveyor. Therefore, the following effects can be obtained. That is, since it is possible to automatically measure the dimensions of the tiles and to sort them based on the measurements, it is possible to improve the efficiency of measuring and sorting the tiles, and to prevent a decrease in the operational efficiency due to omissions in sorting.
