Description

[Detailed description of the invention] This invention is a method for conveying roof tile materials, fired products, etc. by turning them 180 degrees without stopping the flow and supplying them to the next process. This invention relates to a reversing device.

In general, on a roof tile manufacturing line, there are times when it is necessary to change the posture of the roof tile by 180 degrees during the conveyance process of the base material or fired product in order to balance with various processing equipment in the next process. In order to carry out the reversing operation, it is necessary to carry out the reversing operation quickly without stopping the roof tile conveyance line, so it is extremely difficult to perform such an operation mechanically.

In view of such drawbacks, the present invention has been proposed to provide two
A reversal position is set in the middle of the conveyor that conveys the roof tiles with a belt, and below the reversal position there is a pedestal that receives the bottom of the roof tiles on the conveyor and can be raised and lowered freely and 180 degrees intermittently. A stopper is arranged to be rotatable, and a stopper is provided on one side at the lower front of the reversal position, and has an abutment plate that comes into contact with the front end surface of the roof tile in the feeding direction to regulate the stop position of the roof tile. The center of gravity of the stopper is set on the feed direction side with respect to the support shaft so that it is biased into an upright state by its own weight, and the stopper is pivoted so as to be able to rise and fall freely so that it can be engaged with and disengaged from the roof tile conveyance track using the support shaft as a fulcrum. , the rotation center of the pedestal is set at a position eccentric in the feeding direction from the longitudinal center of the roof tile whose position is regulated by contacting the stopper at the reversal position, and the reversal of the fired product. An embodiment of the present invention will be described below with reference to the drawings, with the aim of solving the above-mentioned drawbacks by providing a device. 1 is a conveyor for conveying the raw material or fired product of the roof tile W; Two driven urethane belts 2 are arranged in parallel, and the belts 2 place and support both sides of the lower surface of the roof tile W, so that the roof tile W can be conveyed sequentially and continuously to the next process, A reversing position 3 is set in the middle of the conveyance path of the conveyor 1.

4 is a stopper mechanism disposed at the front lower part of the reversing position 3, and a support piece 6 is erected on a frame 5 disposed below the conveyor 1, and a stopper 7 is attached to the support piece 6. This stopper 7 is pivotally supported using a support shaft 8 as a fulcrum, allowing it to rise and fall freely.
On one side end surface, a contact plate 9 that contacts the front end surface of the roof tile W that is conveyed in an undulating state is molded and fixed with rubber, urethane, etc., and the abutting plate 9 is fixed to the roof by the undulating movement of the stopper 7. A guide roller 1 made of plastic is installed on the top of the stopper 7.
0 is attached as the pivot point.

Further, the center of gravity of the stopper 7 is set on the feeding direction side with respect to the support shaft 8 which is a pivot point so that the stopper 7 is urged into an up-and-down state by its own weight in a normal state.

Reference numeral 11 denotes a block that comes into contact with the other end of the stopper 7 to restrict its position when standing up.

Reference numeral 12 denotes a reversing device disposed below the reversing position 3, and the main shaft 1 is positioned below the conveyor 1 and is controlled to move up and down by a cylinder or the like, and is controlled to alternately forward and reverse rotation by 180 degrees by a motor or the like.
3, and a pedestal 14 is attached to the upper end of the main shaft 13 to receive the lower surface of the roof tile W transported to the reversal position 3 in a state of four-point support.
The rotation center of the main shaft 13 that supports the roof tile W is regulated in position by contacting the stopper 7 at the reversal position 3.
The roof tile W in the reversal position 3 is moved horizontally by the lifting and lowering and intermittent rotation of the main shaft 13.
It is designed to allow you to change your posture 180 degrees.

Further, a phototube 15 is disposed at a position facing above the front end of the roof tile W that stops at the reversal position 3,
When the roof tile W is conveyed to the reversal position 3, a command to start operation is issued to the drive source of the main shaft 13.

Next, to explain the operation of the reversing device for roof tile bases and fired products according to the present invention, the roof tile W such as the base material after molding or the fired product after firing is transferred to the conveyor 1.
When the roof tile W is conveyed along the belt 2 and reaches the reversal position 3, the front end surface of the roof tile W comes into contact with the abutting plate 9 of the stopper 7 and is forcibly stopped at a predetermined position, as shown in FIG. At the same time, the phototube 15 senses the entry of the roof tile W into the reversal position 3, and an activation command is issued to the drive source of the main shaft 13.

In response to this operation command, the main shaft 13 is raised as shown in FIG. 2, and the roof tile W on the conveyor 1 is lifted and supported via the pedestal 14, and the roof tile W on the conveyor 1 is lifted and supported as shown in FIGS. 3 and 4. As the main shaft 13 rotates 180 degrees intermittently at the rising end, the pedestal 14
The roof tile W on the top is reversed back and forth and its attitude is changed 180 degrees in the horizontal direction, and then as the main shaft 13 moves downward, the roof tile W on the pedestal 14 is changed in attitude onto the conveyor 1. It will be placed.

At this time, the main shaft 13, which is the center of rotation of the roof tile W, is set at a position eccentric in the feeding direction from the longitudinal center of the roof tile W, whose position is regulated by contacting the stopper 7 at the reversal position 3. Therefore, as shown in FIG. 5, when the roof tile W is reversed 180 degrees, the position of the front end surface is shifted in the feeding direction compared to before the reversal, and therefore, the roof tile W is not placed on the conveyor 1. At the bottom of the front end of the roof tile W, the abutting plate 9 of the stopper 7
The side is pressed, and the stopper 7 falls down due to the pressing action, moves out of the traveling path of the roof tile W, and the position restriction by the stopper 7 is released, and the roof tile W is sequentially conveyed by the action of the conveyor 1. The stopper 7 is maintained in a depressed and pressed state until the roof tile W passes through the guide roller 10, and after the roof tile W has passed, it returns to the upright state due to its own weight and faces the next roof tile W to be conveyed. It is located.

In short, the present invention consists of a conveyor 1 that conveys roof tiles W using two belts 2 that are driven in circulation.
Set the reversal position 3 in the middle of the reversal position 3.
A pedestal 14 for receiving the bottom surface of the roof tile W on the conveyor 1 is disposed below so that it can be raised and lowered and rotated 180 degrees intermittently, so that no excessive external force is applied to the roof tile W being conveyed. It is possible to change the posture on the inverted position 3 without any trouble, and at that time, the cradle 14
The can repeat forward and reverse rotations of 180 degrees and can be started from either direction, saving time in returning to the original position and contributing to speeding up the conveyance line itself. Since it can be driven by a single main shaft 13, the mechanism is simple, there are few breakdowns, and maintenance and inspection are easy. It can also be installed in a small space, and is lightweight, contributing to energy saving. A stopper 7 is disposed on one side of the lower part and includes a contact plate 9 that comes into contact with the front end surface of the roof tile W in the feeding direction to regulate the stop position of the roof tile W, and the stopper 7 is brought into an upright state by its own weight. The center of gravity of the support shaft 8 is set on the feed direction side so as to be biased, and the support shaft 8 is used as a fulcrum and is pivotally supported so as to be freely movable so as to engage and disengage from the conveyance track of the roof tile W. The roof tile W can be reliably regulated at the fixed position of the reversing position 3, and the reversing operation at this position can be performed smoothly, and after the roof tile W has passed, the stopper 7 can be moved by its own weight without requiring any other driving means. This makes it possible to return to the upright state that provides a stopper effect.

In addition, since the center of rotation of the pedestal 14 is set at a position eccentric to the feed direction side from the center in the length direction of the roof tile W, which is once completed by contacting the stopper 7 at the reversal position 3, When transferring the roof tile W to the conveyor 1 at the end of the process, the position of the front end surface of the roof tile W shifts in the feeding direction compared to before the reversal, so the roof tile W
The position regulating action of the stopper 7 can be automatically released by pressing the abutting plate 9 side of the stopper 7 at the bottom of the front end of the stopper. It has great practical effects, such as simplifying the mechanism and ensuring reliable operation without fear of failure.
