Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for feeding rough ground into a tile press machine, which feeds rough ground onto the lower mold of the tile press machine at high speed and smoothly in precise synchronization with the forming operation of the tile press machine. An example of the implementation of the present invention will be described based on the drawings. Reference numeral 1 denotes a press body for molding tiles that can mold a plurality of tiles at the same time, and is attached to a main shaft 2 that is rotationally driven by a drive motor (not shown). cam for operating the upper die (
A predetermined number of upper molds 3 are attached to the upper molds 3, which are moved up and down by the upper molds 3 (not shown), and the side walls 4 of the press main body 1,
A lower mold 7 is mounted on a swing bed 6 which is rotatably mounted on a pivot 5 between 4'.

A cam 8 having a predetermined shape is provided at one end of the main shaft 2.
an arm 12 having rollers 10 and 11 on one end thereof, which are attached to the cams 8 and 9 in a superimposed state and which roll on the outer periphery of the cams 8 and 9;
is pivotally supported on the side wall 4 by a pivot 13, and the main shaft 2
A fan-shaped gear 14 is formed at the other end of the arm 12, and a gear 15 meshing with the gear 14 is connected to the swing bed 6. The swing bed 6 is attached to the pivot shaft 5 so that one rotation of the main shaft 2 causes the swing bed 6 to be tilted back and forth by a predetermined angle from an upright position toward the take-out portion 16 side.

Reference numeral 17 denotes a delivery section on which the rough land 18 is placed, and is composed of fork-shaped receiving pieces 19, 19', etc., so as to receive the lower surface of the rough land 18 along its shape. It is connected to the conveyor A of the wasteland 18 at the same height, and triangular support plates 20, 20' are placed below these receiving pieces 19, 19'. The supporting plates 20, 20', . The other end of the other support shaft 22 is connected to the side wall 4 of the press body 1,
4' is pivotally connected to a predetermined position via a connecting rod 24, so that as the swing bed 6 tilts, the transfer section 17 moves to a position facing the upper mold 3 downwardly while maintaining a horizontal state.

Reference numeral 25 designates a part of a stopper installed above the transfer section 17, and a rotation shaft 26 is installed between the side walls 4 and 4' of the press body 1.
The upper end of the link 27 is fitted and fixed at both ends of the link 27, and the upper end of the other link 28 is pivoted to the side walls 4, 4' adjacent to the support position of the rotation shaft 26. Support shafts 29 and 30 are inserted between the lower ends of the support shafts 27 and 28, respectively, and hook-shaped stoppers 31. 31'...... is inserted and supported.

The stoppers 31, 31'... are connected to the rotation shaft 2.
The receiving piece 19 of the transfer portion 17 is located at a position facing downwardly from the clay mold 3 when the link 27, 28 moves forward with the rotation of the clay mold 3.
, 19'... is positioned in contact with the rear end surface of the upper rough ground 18, and when retreating, it retreats upward in an inclined manner so that it can escape from the rough ground transport trajectory by the delivery part 17. There is.

Next, the mechanism for rotating the rotation shaft 26 will be explained.
A cam 33 having a groove 32 of a predetermined shape is attached to one end of the main shaft 2, and the roller 3 fits into the groove 32.
The other end of the arm 35, which is provided with a cam 33 at one end, is fitted and fixed to the end of the rotating shaft 26, and one rotation of the main shaft 2 causes the arm 35 to reciprocate by a predetermined angle along the groove 32 of the cam 33. By tilting the arm 35, the rotation shaft 26 is reciprocated by a predetermined angle.

Next, to explain the operation of the rough ground feeding device for the tile press machine according to the present invention, first, before press forming, the swing bed 6 is in an upright state as shown by the chain line in FIG. , 19'...
. . . are waiting outside the press body 1 at the same height as the wasteland conveyor A, and the stoppers 31, 31', . Waiting to retreat above.

From this state, as the main shaft 2 rotates, the upper mold 3
While the machine is descending and press-forming the rough ground 18 on the lower die 7, the rough ground 18 that is continuously transferred on the conveyor is placed on the receiving pieces 19, 19'... of the transfer section 17. Then, the main shaft 2 rotates and the upper mold 3 rises, and the action of the cams 8 and 9 attached to the main shaft 2 moves the swing bed 6 via the arm 12 into a state where the molded material 36 after molding is placed. The swing bed 6 is tilted at a predetermined angle as shown by the solid line in FIG. 19'・
. . . The delivery section 17 placed thereon moves to a position facing the upper mold 3 below while maintaining its horizontal state.

Further, in association with the tilting of the swing bed 6, the rotation shaft 26 which controls the movement of the stopper part 25 via the arm 35 is rotated by the cam 33 which rotates integrally with the main shaft 2, as shown by the solid line in FIG. As shown in , the stopper 31.
31' advance forward and come into contact with the rear end surface of the rough ground 18 on the transfer section 17, which is waiting at a position below the upper die 3.

After that, in the process in which the main shaft 2 further rotates and the swing bed 6 returns, the transfer section 17 also returns together with the swing bed 6, but the rough ground 18 on the transfer section 17 is moved by the stopper 31, 31'... ..., and the roller 34 of the arm 35 that controls the movement of the stopper part 25 is at the deepest part 3 of the cam 33.
7, the stoppers 31, 31', . Then, the main shaft 2 further rotates and the swing bed 6 returns to a completely upright position, and the transfer section 17 also returns, and the stopper part 25 also returns to the backward position by the action of the cam 33, completing one stroke.

In this way, the rough ground 18 is supplied onto the lower mold 7,
By repeating the above operations, the rough ground 18 is continuously fed in synchronized with the press operation.

Note that the vertical movement of the upper die 3 in the press body 1 is not limited to a cam type press, and may of course be performed by a crank type, hydraulic type, or the like.

In short, in the present invention, a lower mold 7 is attached to the upper surface of the swing bed 6, which is tilted back and forth at a predetermined angle. A delivery part 17 is installed which reciprocates between the lower facing position and the upper die 3 while maintaining a horizontal state.
The rough ground 18 on the transfer section 17 when the
A stopper 31 that contacts or slightly pushes out the rear end surface.

5 is provided, and a delivery section 1 is provided in conjunction with the swing bed 6.
Stoppers 31 and 31' are placed on the rear end surface of the rough surface 18 on the transfer section 17 while the mold 7 returns from the position facing the upper mold 3.
Since the swing bed 6, the transfer section 17, and the stopper part 25 are caused to operate in a related manner by the cams 8, 9, and 33 fitted to the main shaft so as to contact or push out a little, The swing bed 6 is tilted to move the molded blank 36 together with the lower mold to the take-out part 16 side after the press molding is completed, and the rough ground 18 transported by the transport conveyor A is transferred to a position facing the upper mold 3 below. The operation of the delivery part 17 and the waste land 18 of the delivery part 17
It is possible to completely synchronize the operations of the stopper part 25 that feeds the material onto the lower die 7 in relation to the rotation of the main shaft 2 without having to individually operate them using a detection switch or the like, thereby achieving high-speed press work. The practical effects are tremendous, such as making it possible to reliably and smoothly continuously supply the rough ground 18 and to significantly improve press work efficiency.
