Description

[Detailed description of the invention] Industrial application field The present invention is applicable to a trolley-type tunnel furnace in which a running rail on which a trolley for carrying objects to be fired runs is laid inside and outside the kiln. A transfer platform that moves along a passage provided perpendicular to the end is provided with a mounting rail that is perpendicular to the direction of movement, and the transfer platform is stopped at a position where the mounting rail coincides with the end of the traveling rail, and the platform is moved. The present invention relates to a device for fixing the transfer platform at a position where the mounting rail accurately matches the traveling rail in a bogie transfer platform in which a carriage is transferred between a traveling rail and a mounting rail.

Problems to be solved by conventional techniques and ideas For example, in a bogie-type tunnel furnace, a running rail is laid through the tunnel-shaped furnace body, and a running rail is laid outside the furnace body parallel to the furnace body. A passage connecting both ends of both running rails is provided at the inlet and outlet of the furnace body, and a mounting rail is laid on a transfer platform that reciprocates between both ends of both running rails along the passage. On the exit side of the furnace, the cart carrying the fired material is transferred to a transfer table, transferred to one end of the running rail outside the furnace, and transferred to the running rail to place the fired material at a predetermined position. The fired product is unloaded from the trolley, the unfired new fired material is loaded onto the trolley, and it is driven to the other end, transferred to another transfer table, and transferred to the entrance side of the furnace body and transferred to the running rail inside the furnace. transfer,
Firing is performed while moving inside the furnace to the exit side, but when transferring the trolley between the mounting rail on the transfer table and the running rail inside and outside the furnace, it is necessary to The transfer platform may not stop at a position where the mounting rail on the transfer platform and the loading rail on the transfer platform are exactly aligned, or even if they match when stopped, play in the drive chain of the transfer platform may cause the platform to change positions. If the transfer platform moves and becomes misaligned, there is a risk that the truck may derail, or the truck may shake significantly and cause the cargo to fall apart.

For this reason, in the past, the transfer platform was stopped and fixed at a predetermined position by protruding the latch claw manually or automatically using an actuator such as a hydraulic cylinder, but in the case of manual operation, unmanned operation is required. However, when an actuator such as a hydraulic cylinder is used, the structure becomes complicated and the manufacturing cost becomes high.

The present invention eliminates these drawbacks, has a simple structure, automatically fixes the transfer table in the position where the rails match, and further corrects any slight misalignment of the stop position of the transfer table. The object of the present invention is to provide a device that allows accurate rail alignment.

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention engages with a reciprocating member provided on a transfer platform to perform transfer by locking to a cart, and moves forward and backward by its reciprocating motion. A connecting rod is provided on the transfer platform, a receiver is provided near the end of the traveling rail to fit the connecting rod almost tightly, and the other party is guided to at least one of the corresponding ends of the connecting rod and the receiver. The structure is such that a slope is formed.

Function The present invention has the above-mentioned configuration, in which the connecting rod fits into the receiver as the reciprocating member moves forward, and the transfer table is fixed at a position where the traveling rail and the loading rail match.
Due to the double movement, the connecting rod comes off and is released.
Furthermore, since slopes are formed at the corresponding ends of the connecting rod and the receiver to guide the other party, even if there is a slight deviation in the stop position of the transfer table, the reciprocating member can be quickly moved at the beginning of the forward movement. Accurate rail alignment is performed while correcting the position of the transfer table.

Embodiment An embodiment in which the present invention is applied to a cart-type tunnel furnace will be described below with reference to FIGS. 1 and 2.

On the floor 1 inside the tunnel-shaped furnace body, a traveling rail 2 for running a trolley is laid penetrating from the entrance to the exit of the furnace body, and on the side of the furnace body, there are rails 2 for loading and unloading the materials to be fired. A running rail (not shown) constituting a running path for a bogie is laid parallel to the above-mentioned running rail 2, and a transfer rail 4 is installed in a pit 3 bored so as to connect both ends of these running rails 2. is laid at right angles to both traveling rails 2, and the wheels 6, 6 of the transfer platform 5 are placed on this transfer rail 4,
Drive force transmitted from the output shaft side of the drive motor 7 attached to the front end of the transfer table 5 to one axle 11 via the sprocket 8, chain 9, and sprocket 10 causes the transfer table 5 to move along the transfer rail 4.
It is designed to reciprocate between the ends of both traveling rails 2 along the transport platform 5, and a loading rail 13 is installed on the top surface of this transfer platform 5, which is perpendicular to the direction of movement. At the end of the running rail corresponding to the inlet side of the furnace body, a cart loaded with a new unfired material to be fired is placed on the loading rail 13 of the transfer table 5.
When the transfer table 5 moves to the inlet side of the furnace body and stops at a position where the mounting rail 13 coincides with the traveling rail 2 inside the furnace body, the transfer table 5 attached to the opposite end of the transfer table 5 The operation motor 15 is started, and the drive shaft 20 having a pinion 21 fixed to the tip thereof is driven via the sprocket 16, chain 17, and sprocket 18, and the above-mentioned pinion 21 installed between the mounting rails 13 is driven. A reciprocating member 23 with a rack 22 attached to its lower surface that engages with the reciprocating member 23 is guided by guide rollers 24 and advances toward the furnace body. spans over a first sprocket 27 pivotally supported at the end of the furnace body side,
The both ends of the chain are pulled by the first chain 29 fixed to the sliding body 26 and the fixed member 28 protruding from the transfer table 5, respectively, so that the reciprocating member 23 is moved from the end opposite to the furnace body to the furnace body side. The cart slides to the end, and accordingly, the push plate 30 on the sliding body 26 pushes the cart and transfers it from the mounting rail 13 onto the traveling rail 2. When the transfer is completed, the drive shaft 20 rotates in the reverse direction. As the reciprocating member 23 retreats, the sliding body 26
is spanned over a second sprocket 32 that is pivotally supported at the end of the reciprocating member 23 opposite to the furnace body, and
It is pulled back to its original position by being pulled by a second chain 33 whose both ends are fixed to the sliding body 26 and the above-mentioned fixed member 28, respectively, and on the outlet side of the furnace body, the above-mentioned reciprocating member 23 is moved back. In this step, the carriage loaded with fired objects is transferred from the running rail 2 inside the furnace onto the mounting rail 13 of the transfer table 5 by the locking pawl 35 on the sliding body 26. There is.

A pair of elongated connecting rods 41, 41 are inserted into the mounting rails 13, 13 of the transfer table 5 described above through a plurality of guide tubes 42 fixed to the mounting rail 13, and the length of the mounting rail 13 is extended. It is attached so that it can slide freely along the horizontal direction, and each connecting rod 41, 41
At the end of the furnace body side, there is a tapered surface 4.
3 and 43 are formed, and both connecting rods 4
One abutment plate 4 at the end opposite to the furnace body 1, 41
4 is fixed across the connecting rods 4, and tension coil springs 46, 46 are installed between the abutting plate 44 and the hanging members 45, 45 protruding from the transfer table 5.
1 and 41 are applied with a moving force toward the furnace body, and the abutting plate 44 abuts against the end of the reciprocating member 23, thereby restricting its movement.
1 and 41 are held in a position where the ends with tapered surfaces 43 are retracted from the ends of the mounting rails 13 and 13, and the running rails 2 and 2 in the furnace body
A pair of receiving tubes 48, 48, which fit substantially tightly with the connecting rods 41, 41, are fixed to the ends of the rods.

Next, the operation of this embodiment will be explained.

When the reciprocating member 23 starts advancing toward the furnace body while the transfer table 5 moves to the inlet side or the outlet side of the furnace body and stops, this reciprocating member 23, which also serves as a stopper for the abutment plate 44, moves toward the furnace body. By moving toward the furnace body, the impact plate 44 is pulled by the spring force of the tension coil springs 46, 46, as shown by the chain line in FIG. 1, and the tips of the connecting rods 41, 41 are moved toward the furnace body. The transfer platform 5 is fitted into the protruding receiver tubes 48, 48 provided on the running rails 2, 2, and is fixed with the mounting rail 13 and the running rail 2 accurately aligned. When the member 23 moves backward in the direction away from the furnace body, in the final stroke of the backward movement, the reciprocating member 23 pulls the abutment plate 44 against the spring force of the coil springs 46, 46 on the side opposite to the furnace body. By this, the connecting rod 41,
41 is removed from the receiving cylinders 48, 48, and the transfer table 5 is released from being fixed.

Further, since tapered surfaces 43, 43 are formed at the tips of the connecting rods 41, 41, if strong springs are used as the tension coil springs 46, 46, the mounting rail 13 and the running rail 2 may be slightly misaligned. Even if the transfer table 5 is stopped in this state, when the connecting rod 41 is fitted into the receiving cylinder 48, it is guided and centered by the tapered surface 43, and the position of the transfer table 5 is aligned with the loading rail 13 and the traveling rail 2. is corrected to a predetermined position that matches.

In addition, if a weak spring that cannot correct the position of the transfer table 5 is used as the tension coil spring 46, the transfer table 5 will stop at a position where the mounting rail 13 and the traveling rail 2 are misaligned. Connecting rod 4
1 does not fit into the receiving tube 48 and its advancement amount is restricted. Therefore, for example, a limit switch is provided near the abutment plate 44 so that the connecting rod 41 does not fit into the receiving tube 48.
It may also be possible to detect that the transfer table 5 is not inserted into the internal space and to sound an alarm buzzer to notify that the transfer table 5 is not stopped at a predetermined position.

In addition to the above-mentioned embodiments, the present invention also includes, for example,
A trolley-type tunnel drying oven is installed on the top of the trolley-type tunnel kiln, and the trolleys that come out of the drying oven are lowered one after another and transferred to the entrance side of the kiln.It can also be used to align the rails of an elevating-type trolley transfer platform. In the case of this elevating type, the transfer table moves up and down when the cart is transferred, and a step is likely to occur between the rails, so positioning using the above-mentioned connecting rod is effective.

Effects of the Invention As explained above, the present invention provides a connecting rod that moves forward and backward while engaging with a reciprocating member for transferring a trolley to a transfer platform, and is fitted almost tightly with the connecting rod near the end of the traveling rail. Since the transfer table is fixed by the fitting of the connecting rod and the receiving device as the reciprocating member moves forward, it can be automatically transferred with a simple structure without using a special actuator. The transfer platform can be fixed at the position where the rails match, and furthermore, a slope is provided on either the corresponding end of the connecting rod and the receiver to guide the other party,
Even if the transfer table is slightly misaligned, the position of the transfer table can be corrected to accurately align the rails.
