Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for transferring continuously delivered uncured molded products such as cement compositions to pallets for transportation.

To explain the present invention in terms of an apparatus for producing a cementitious composition, as shown in FIG. An uncured molded product 1' (hereinafter simply referred to as a molded product) is transferred from a transfer conveyor 2' to a pallet 3' located below it.

For the above-mentioned transfer, a conveyor-like pallet extrusion device 4' is moved by a drive wheel 5' to an arrow 6'.
The pallet 3' is pushed in the direction of the arrow 8' by the pusher 7' mounted on the conveyor, and the conveying speed of the pallet 3' is made equal to the moving speed of the transferring conveyor 2'. Let's do it. Reference numeral 9' designates free roller conveyors installed on both sides of the pallet extrusion device 4' in the axial direction (FIG. 5). The pallet 3' separated from below the transfer conveyor 2' is transferred toward the right in FIG. 4 by a driving roller 10' provided at a key point between the free roller conveyors 9' and sent to the curing process.

This kind of conventional device is a rear push type, which is a guiding method that only pushes from the rear, and does not involve a means for advancing the pallet in a straight line, so the pallet 3' is moved left and right on the pallet extrusion device 4' with respect to the transport direction. Easy to swing. In addition, if the back surface of the pallet 3' becomes damaged and irregular due to repeated use, it will create frictional resistance on the free roller conveyor, making it difficult to move smoothly, or causing vertical vibration, which will further increase the runout. . When an uncured molded product is transferred onto the pallet 3' in such a state, the uncured molded product is transferred in a meandering manner, and when it is completely cured, it becomes a defective product that is not linear.

The present invention aims to eliminate the above-mentioned drawbacks. According to the present invention, a long uncured molded product extruded from an extruder, cut into predetermined lengths, and sent at regular intervals is placed from above the transfer conveyor to below the conveyor. A device for transferring the molded parts onto the pallets fed by a pallet extrusion device, the pallet extrusion device having at least two horizontally arranged rails and a protrusion at the tip facing the molded product transfer direction. Further, the rear end facing the protrusion has a clamping fluid pressure cylinder to removably clamp the pallet fed between the protrusion and the hydraulic cylinder, and a long cart movable on the rail. a rack fixed to the truck over almost the entire length thereof; a drive pinion for driving the rack in the molded product transfer direction and the opposite direction to reciprocate the truck; and a truck and pinion having the rail and rack. and a device for integrally raising and lowering the frame body provided with the frame body, and further provided on both sides of the truck at a level near the bottom of the pallet when the frame body is raised, for receiving and transferring pallets from the truck. The present invention provides an apparatus for transferring uncured molded products, which is equipped with a conveyor.

Prior to explaining the apparatus of the present invention, an apparatus for transporting cut long uncured molded products at regular intervals will be described. This transfer device has been used conventionally, and the transfer device described with reference to FIG. 4 also has a device similar to this in the previous process.

As shown in FIG. 1, an uncured molded product 1 extruded from an extruder (not shown) is transported by a molded product cutting conveyor 2 arranged in series with a constant low speed feed, and a variable speed conveyor 2 with a variable speed switchable between low and high speed feed. It is transported on a conveyor 3 and a constant high speed transfer conveyor 4. A free roller conveyor 5 is disposed between the conveyors 2 and 3 and between the conveyors 3 and 4, and a free roller conveyor 6 arranged in an inclined manner downstream of the conveyor 4 is disposed.

In FIG. 1A, conveyors 2 and 3 are fed at the same low speed, and conveyor 4 is fed at a constant high speed. The molded product 1 is cut on a cutting conveyor 2 by a cutter (not shown) to form molded products 1', 1'', etc. of a predetermined length. Not separated.

FIG. 1B shows a state in which the molded product 1' is being transferred from the conveyor 2 to the conveyor 3 at the same speed.

In FIG. 1C, the molded products 1' and 1'' are separated at the cut 7 where the conveyor 3 is switched to the same high speed as the conveyor 4, and the molded product 1' is transferred on the conveyor 3 as shown in FIG. 1D. Ru.

As shown in Fig. 1E, when the molded product 1' is completely transferred onto the conveyor 4, the conveyor 3 is switched to the same low speed as the conveyor 2 again, and the molded product 1'' to be sent next is transferred. The above-mentioned steps are then repeated so that the molded products 1 can be transferred onto the conveyor 3.The thus cut molded products 1 are sent onto the transfer conveyor 4 at regular intervals.

Embodiments of the present invention will be described below with reference to FIGS. 2 and 3. FIG. 2 is a plan view of the device of the present invention;
FIG. 3 is a side view of FIG. 2. In FIG. 2, the transfer conveyor shown in FIG. 3 and the inclined free roller conveyor following it are omitted for clarity.

As shown in FIGS. 2 and 3, a pallet extrusion device 10 is installed below the above-mentioned transfer conveyor 4.
A transfer device including a delivery conveyor 30 is provided.

The pallet extrusion device 10 has a frame 12 on a foundation or a fixed table via an elevating device 11 consisting of a plurality of fluid pressure cylinders.
A plurality of rails 13 are arranged in parallel in the transport direction. A long cart 14 movable on the rails 13 is placed. A pallet 16 to be placed is placed at the front end of the cart 14 facing the direction 15 in which the molded product 1 is transported.
A protrusion 17 that serves as a stopper that comes into contact with the front end
A clamping fluid pressure cylinder 18 for pressing the rear end of the pallet 16 in the transfer direction 15 is fixed to the rear end of the truck 14. A rack 19 is fixed over almost the entire length of the truck 14, and is driven in the transport direction of the molded product 1 and in the opposite direction by a pinion 20 which is attached to the frame 12 and can be driven in forward and reverse directions.

The delivery conveyor 30 includes a free roller conveyor 31 and a drive roller conveyor 32, and the frame body 1
They are placed on both sides of the truck 14 at the bottom level of the pallet 16 when the pallet 2 is raised.

During operation, as shown in FIG.
4 and is pressed and fixed against the protrusion 17 by the piston of the fluid pressure cylinder 18. Upon receiving a signal that the uncured molded product 1 has been sent onto the transfer conveyor 4, the pinion 20 is rotated, the rack 19 is driven, and the cart 1 on which the pallet 16 is placed is rotated.
4 to the right in a timely manner to receive the uncured molded product 1 as shown in FIG.

Next, as shown in FIG. It comes off. Prior to this, when the piston of the clamping fluid pressure cylinder 18 is retracted, the pallet 16 carrying the molded product 1 is released from the cart 14 and sent to the delivery conveyor 30 for the next process, for example, a curing process. . still,
By lowering the truck 14 while pressing the pallet 16 with the piston of the clamping hydraulic cylinder 18, it is also possible to extract the pallet onto the delivery conveyor 30.

In the state shown in FIG. 3C, the pinion 20 is reversed to send the cart 14 to the left in the figure, and the lifting device 11 lifts the frame 12 to lift the next supplied pallet 1.
Receive 6.

According to the apparatus of the present invention, the pallet is clamped to the cart by the protrusion and the fluid pressure cylinder, and the cart is moved along a plurality of rails, so that lateral vibration of the pallet is prevented during transfer of uncured products. It is possible to completely prevent unstable displacement such as, etc., and therefore no defective products will be produced when the molded product is cured.
