Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a tire type reading device used in a tire sorting yard of a tire factory.

[Conventional technology]

In a tire factory, for example, the types of products flowing into a warehouse are not constant, and various types of products flow irregularly. Therefore, a sorting operation is required. Conventionally, this sorting work has depended on humans.

[Problems to be solved by the invention]

In order to automate the tire type reading operation, which has conventionally relied on human power, the following functions must be provided.

(1) The identification mark to be attached to the tire can be read on the inner surface of the tire because the inner surface of the tire is desired from the viewpoint of commercial value and the preservability of the mark.

(2) Since the mold release agent and the like are applied to the inner surface of the tire due to manufacturing technology, the process is performed without being obstructed by the mold release agent and the like.

(3) Since the position of the identification mark is not constant, the mark can be read on the entire inner circumference of the tire.

[Means for solving the problem]

A centering device that is provided on the tire transport device, detects that the tire has been transported to a predetermined position, operates and performs centering of the tire, and is installed above the centering device, and when the tire is centered, A driving mechanism for moving the moving bar in the axial direction, the radial direction, and the circumferential direction with respect to the center thereof, and a driving mechanism including the moving bar, and a driving mechanism provided below the moving bar and in a tire centered by the driving mechanism. A cleaning device that is inserted and moved in the radial and circumferential directions to clean the inner surface of the tire, a tire type reading sensor that reads an identification mark provided on the inner surface, and a position that does not hinder the transfer of the tire by the tire transfer device. And a cleaning device for cleaning the cleaning device that is moved to the position at an appropriate frequency, and is transported by the tire transport device. And characterized in that a readable the type of tire automatically that.

[Action]

(1) The centering device accurately positions the tire position with respect to the frame device.

(2) The frame device allows a sensor and a cleaning device to approach a predetermined position on the inner surface of the tire so that cleaning and mark reading are possible.

(3) The dirt on the tire inner surface cleaner attached to the head is refreshed by the cleaning device.

(4) The sensor identifies the identification mark.

Reference numeral 16 denotes a chain (or a belt) stretched on a sprocket mounted on the upper end of the geared motor 12 and the elevating feed screw 10. Reference numeral 17 denotes a cleaning device. And is fixed to the pillar 11. Cleaning equipment
17 is provided at a place where the cleaning device 3 can be approached without obstructing the passage of the tire. Reference numeral 21 denotes a centering roller, which is located in the center area of the tire width in the height direction. 22 is the centering roller 21
23 is a gear attached to the arm 22 and 2
The rotational motions of the centering rollers 21 are symmetrically moved. Reference numeral 24 denotes a lever, reference numeral 25 denotes a ring, and reference numeral 26 denotes a lever, which has a function of symmetrically synchronizing the rotational movements of the centering roller 21 and the arm 22 on the right side of FIG. Reference numeral 27 denotes an air cylinder which moves the four centering rollers 21 concentrically to position and hold the center of the tire 101 to be identified as the rotation center of the shaft 6. Said 2
The components 1 to 27 form the centering device 28. 102 is a tire transport device, 103 and 104 are transmissive auto-switch light emitting and receiving devices that detect the passage of the tire and detect the tire diameter based on the time required for the passage, and control the tire transport device 102 to stop immediately below the axis 6. I do.

 Next, the operation will be described.

(1) The tire 101 is transported on the tire transport device 102.

(2) The flat switches 103 and 104 detect the arrival of the tire 101 and the diameter of the tire 101, and stop the tire transfer device 102 when the tire 101 is transferred near immediately below the shaft 6.

(3) The tire 101 is centered and held by pulling the air cylinder 27.

(4) The geared motor 12 is lowered and stopped by the auto switch 4 at a height corresponding to the tire width.

(5) The cleaning device 3 is brought into contact with the tire inner wall by the pulling operation of the cylinder 7. At this time, the radial reading position of the sensor 1 is also determined at the same time.

(6) When the air cylinder 8 is pushed (the next time, the pulling operation is alternated), the cleaning device 3 and the sensor 1 rotate once,
The sensor 1 reads a tire identification bar code on the inner surface of the tire.

The cleaning device 3 includes a sensor 1 and a light 2 when viewed from above.
(In the case of one, there is no precedence of the cleaner 3 in the case of the alternate operation of the shaft 6).

(7) The cleaning device 3 is returned to the center of the tire by pushing the air cylinder 7.

(8) The geared motor 12 is raised and the sensor 1
Then, the cleaning device 3 is stopped at the prescribed ascending position.

(9) The tire is released by pushing the air cylinder 27.

(10) The tire transport device 102 is driven to send out the tire.

This is one cycle, but the next cleaning cycle of the cleaning device 3 is performed at a required frequency.

(1) Pull the air cylinder 7 to bring the cleaning device 3 into contact with the cleaning device 17.

(2) The cleaning device 3 and the cleaning device 17 are rotated, filled with water, washed for a certain period of time, and stopped.

(3) Push the air cylinder 7 to return to the standby state.
