Description

[Detailed description of the invention] This invention reliably feeds relatively weak plates such as veneer veneer and fiberboard onto the loader shelves installed in multiple stages in the loader cage frame of a multi-stage hot press. Therefore, the present invention relates to a delivery device that moves back and forth intermittently relative to the loader shelf.

Usually, a loader device having loader shelves with a number of stages corresponding to the number of hot plate stages is installed on the insertion side of a multi-stage hot press.
Since the loader cage frame is configured to be able to move up and down, a pair of upper and lower pinch rollers is installed at a predetermined interval in front of the loader device, and the temporarily glued plywood is lifted and stopped intermittently via these pinch rollers. A method was adopted in which the loader was fed sequentially onto each stage of the loader shelf in the loader cage frame.

However, in the case of a material with relatively strong plate body strength such as temporarily bonded plywood, the plate body has straightness, so feeding and receiving is generally performed smoothly from the pinch roller to each stage loader shelf spaced apart from the pinch roller by a predetermined distance. Although problems such as buckling and breakage of the front edge do not occur, when the plate body strength is weak such as veneer veneer or fiberboard, when transferring it to each stage loader shelf using the above method, By the time the edge reaches the front end of the loader shelf, it becomes bent or hits the front end of the loader shelf, causing buckling, breakage, etc., and smooth feeding and receiving becomes impossible.

In view of the above, the present invention was developed when performing contact heating drying of veneer veneer, heat pressing of fiberboard, etc. using a multi-stage hot press.
The delivery device that feeds weak plates onto the loader shelves of each stage of the loader device is configured to be able to move forward and backward with respect to the loader shelves, and moves forward in synchronization with the loader cage frame which intermittently stops rising. An embodiment of the invented device will first be described in terms of its configuration, based on the accompanying drawings.

For convenience, this example shows the case where a veneer veneer is contact-heated and dried using a multi-stage hot press.
A delivery device will be described in which a feeding conveyor 3 is used to control the transfer of the intermediate plate 2, which is a fiber perpendicular to the fiber direction of the fiber.

The original plate 1 is located on the side of the feed conveyor 3, the fibers are parallel to the insertion direction of the feed conveyor 3, a plurality of sheets are stacked as a set of front and back plates, and the upper surface is held in an appropriate position. In front of the lifting table 4, a pair of upper and lower pinch rollers 5 for inserting the original plate 1 onto the feeding conveyor 3 is installed.

The intermediate plate 2 is located in front of the feed conveyor 3, and the fibers are parallel to the insertion direction of the feed conveyor 3. In this embodiment, two sheets are arranged in parallel for the insertion width, and a plurality of each sheet is stacked. The conveyor 3 is placed on a lifting table 6 that can hold the conveyor 3 in an appropriate position, and in front of the lifting table 6 is a pair of upper and lower pinch rollers 7 for inserting the two middle plates 2 arranged side by side onto the conveyor 3. is set up.

The feed conveyor 3 supports a plurality of rolls 10 between bearings 9 installed at predetermined intervals on a machine frame 8, and has grooves cut at regular intervals over the longitudinal direction of the rolls 10. The rolls 10 are connected by a connecting body 11 such as a belt or chino suspended in the groove portion, and the original plate 1 or the intermediate plate 2 is transferred straight to a delivery device to be described later. In the gap between each roll 10, there is a stopper 12 which is swingable by a fluid cylinder 12 supported on the upper side end of the machine frame 8 so as to hold the original plate 1 perpendicularly to this straight movement.
In order to carry out orthogonal transfer to point A, an orthogonal transfer conveyor 13 is provided which can rise and fall freely starting from the height of the rolls 10.

This orthogonal transfer conveyor 13 has a chute 15 fixed on a machine base 14 that can face the rolls 10 apart, and also has rollers 16 loosely attached close to the chute 15. The guide 17 fixed to the bottom of the four corners of the machine base 14 is pivoted to a cam 20 with the bearing 19 on the frame 18 as a fulcrum, and the lower ends of the cam 20 are connected by a connecting shaft 21. connected, and the connecting shaft 21
A piston rod of a fluid cylinder 22 is attached to the horizontal shaft extending between the two, and the machine base 14 can be raised and lowered via the cam 20 by the operation of the fluid cylinder 22.

In front of the machine frame 8 in the straight forward transfer direction, a shaft 25 is mounted on a frame 23 erected on the machine frame 8 via a bearing 24, and an opening/closing body 26 is attached to the shaft 25. The shaft 25 is rotated by the operation of the fluid cylinder 27, so that the opening/closing body 26 can be opened and closed at a required angle in the transfer direction.

A cantilever-shaped pedestal 28 is erected on both sides adjacent to the front side of the
A fluid cylinder 30 is attached to approximately the center of the cross beam 29 that is suspended between the pedestals 23, and both ends of a guide bar 32 attached to the tip of the piston rod 31 are connected to the horizontal surface of the pedestal 28. It is connected to a regulating body 33 mounted on the upper front part.

On the other hand, a guide plate 35 having an elongated hole 34 drilled to a certain length is attached to the rear portion of the horizontal plane of the pedestal 28, and the regulating body 3
a pinion 37 that engages the guide roller 36 attached to the pinion 3 in the elongated hole 34 and is attached to the regulating body 33;
The movement of the regulating body 33 is regulated by meshing with a rank 38 installed on the pedestal 28.

Further, at the lower part of the regulating body 33, a pair of upper and lower clamping belts 39 consisting of a plurality of rows of belts, chinos, etc. are suspended by the upper and lower boot IJ40, 40' portions serving as the base ends, and the transfer device 4
1.

A loader cage frame 42 is installed at a predetermined distance from the transfer device 41 in a loader support (not shown) so as to be able to move up and down. A plurality of loader shelves 43 of a corresponding number are installed at board intervals, and a loader device 44
It consists of

Next, the operation of this embodiment will be explained.

First, while contact heating and drying the original plate 1 or intermediate plate 2 supplied between the hot plates of the multi-stage hot press, the loader cage frame 42 reaches its lowering limit, and the clamping transfer band 39 of the delivery device is located at the forward limit position, that is, at the rear end of the uppermost loader shelf 43.

At this time, if the next veneer veneer sheet to be supplied to the multi-stage hot press is the original sheet 1, the piston rod of the fluid cylinder 12 is contracted on the feed conveyor 3, the stopper 12A is lowered, and the fluid cylinder 22 is The piston rod is extended and the cam 20 is swung upward using the bearing 19 as a fulcrum, and the machine base 14 is raised until the upper surface of the orthogonal transfer conveyor 13 floats above the upper surface of the rolls 10.

A worker or a known feeding device picks up the uppermost original sheet 1 from the pile of original sheets 1 deposited on the lifting platform 4, and the original sheet 1 with its fibers parallel to the insertion direction is placed on the feed conveyor 3. It is inserted through the pinch roller 5 from the side of the navel.

The inserted original plate 1 is rotated on the chute 15 by the rotation of the rollers 16, is orthogonally transferred on the feed conveyor 3, reaches the stopper 12A located on the other side, and the sides are once aligned.

Next, the orthogonal transfer conveyor 13 is lowered from the upper surface of the roll 10 by an operation opposite to that described above, and the feed conveyor 3
The opening/closing body 26 detects the presence of the upper original plate 1 and enters the closed state.
Up to this point, the fibers of the original sheet 1 are transported in a straight line orthogonal to the traveling direction by the rotation of the rolls 10, but the fibers are rolled into the gaps between the rolls 10 and buckled by the connecting bodies 11 suspended between the rolls 10 in multiple rows. etc., and the front edge of the forward hip is aligned.

Thereafter, when the shaft 25 is rotated by a required angle by the operation of the fluid cylinder 27, the opening/closing body 26 is opened, and the original plate 1 is transferred onto the delivery device 41 located at the forward limit, and is placed between the pair of upper and lower holding and transferring bands 39. The loader is transferred onto the uppermost loader shelf 43 of the loader cage frame 42 while regulating its position.

After the transfer is completed, the delivery device 41 causes the regulating body 33 mounted on the horizontal surface of the pedestal 28 to engage with the guide roller 36 and the elongated hole 34 of the guide plate 35 due to the contraction of the piston rod 31 of the fluid cylinder 30. As the pinion 37 and the guide roller 36 move back to the horizontal backward limit position due to the meshing action between the pinion 37 and the rank 38, that is, the pinion 37 and the guide roller 36 move back to the position shown by the dashed line in Figure 4, the regulator 33 is suspended from the lower part. The front ends of the pair of upper and lower clamp transfer bands 39 are separated from the rear end of the loader shelf 43 to the position shown by the dashed line in Figure 4, and the delivery state is released.

When the delivery state is released, the loader cage frame 42 moves up intermittently until the next stage loader shelf 43 reaches the insertion position of the original plate 1, and then stops once, and this intermittent rise is detected by a detector as appropriate.
The transfer device 41 is again moved forward to the forward limit by the operation opposite to that described above, and brought into a transfer state with the next stage loader shelf 43.
It shall be prepared for the original plate 1 to be transferred next.

The rotor cage frame 42 is orthogonally transferred and straightly transferred as described above by the intermittent upward movement of each stage, and the delivery device 41
When the original plate 1 fed through is sequentially transferred to each stage loader shelf 43 until reaching the upper limit and the multi-stage hot press is opened, each stage loader shelf 43 moves forward in the direction of the multi-stage hot press by appropriate means. .

Next, the veneer veneer is fed to the multi-stage hot press as the middle plate 2.
In this case, in the feed conveyor 3, the piston rod of the fluid cylinder 12 is extended, the stopper 12A is raised and retracted from the direction of transporting the intermediate plate 2, and the piston rod of the fluid cylinder 22 is contracted, and the orthogonal transport conveyor 13 is The upper surface is maintained in a state sunken below the upper surface of the roll 10.

The middle plates 2 are a set of two, and the fibers thereof are parallel to the insertion direction, and the uppermost one is fed from the lifting table 6 by an operator or a known feeding device through the pinch rollers 7 to the conveyor 3. inserted from the front.

The intermediate plate 2 inserted onto the feed conveyor 3 is transferred onto each stage loader shelf 43 in the same way as the straight transfer of the original plate 1 described above.

Note that while the fibers of the intermediate plate 2 are perpendicular to the straight direction of the original plate 1, the fibers of the intermediate plate 2 are parallel to each other, so compared to the original plate 1, the strength of the plate during transportation is lower than that of the original plate 1. Failures such as edge buckling are relatively unlikely to occur.

As described above, according to the device of the present invention, the transfer device, which can move forward and backward with respect to the loader shelf, advances the weak plate body transferred via the feed conveyor in synchronization with the loader cage frame, which stops rising intermittently, and the loader device As described above, it has the function of smoothly transferring onto each stage loader shelf.
This eliminates the drawbacks of conventional systems, such as bending, buckling, and damage up to the front end of the loader shelf.
