Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for carrying plate bodies such as plywood, decorative boards, or veneer veneers into a horizontal multi-stage press between hot plates arranged in parallel at equal intervals. This relates to a shelf linking device for transporting containers from the warehouse.

Normally, the multistage press that is mainly used in the plywood manufacturing process has a movable platen that can be raised and lowered by a ram cylinder installed in the lower frame, and is equipped with multiple stages of hot plates between the upper and lower frames. After inserting and placing the plate to be processed in between, the movable platen is raised, and the hot plate above it is pushed up in sequence starting from the lowest hot plate, the press is closed, and the process is heated and pressurized for the required time. He had obtained a completed board.

However, in this type of multi-stage press having multiple upper and lower heating plates, when supporting each stage of heating plates,
A method is adopted in which support claws are attached to the four corners, and these support claws are sequentially placed on ladder-like supports attached to pillars. Therefore, when determining the thickness of the heating plate at each stage,
In addition to the strength required to heat and press the plate, which is the main purpose, the thickness is greater than necessary because it has to be made rigid by taking into account the strength required to cope with the deflection and bending caused by the distance between the fulcrums.

Furthermore, arranging hot plates that are thicker and heavier than necessary in multiple stages means that the upper and lower parts of the plate placed on the hot plate are Not only does this increase the variation in pressurizing force at each stage, resulting in poor adhesion and thinning of the treated plates, but also the diameter of the ram cylinder, which is the means to raise and lower the hot plates at each stage, and the supply of fluid to the cylinder. This increases the pump capacity and the load on the fluid pressure unit, which necessitates an increase in the size of the multi-stage press.

For this reason, by adopting a horizontal multi-stage press in which hot plates are arranged side by side in contrast to a multi-stage press in which multiple hot plates are arranged above and below, the pressure applied to the processed plate after heating and pressing can be increased. Attempts have been made to correct the variation in the temperature, reduce the weight of the hot plate, or downsize the fluid pressure unit. In parallel, when the press is opened, the plate to be processed is carried in an upright position between the hot plates of a horizontal multi-stage press, which are arranged side by side at equal intervals, or the processed plate is carried out in an upright position. A device is required to do this.

Generally, these devices are located close to each other, but because they need to be driven separately and independently, they are fixedly arranged at regular intervals. Therefore, the plate to be processed or the processed plate must be transferred from between the shelves of the carry-in device to between the hot plates, or from between the hot plates to the shelves of the carry-out device. It is necessary to regulate the spacing between the hot plates to be in the same phase.

However, due to thermal expansion of the members supporting each column in the carrying-in or carrying-out device, and mechanical errors caused by changes over time, a phase shift occurs between each shelf and between the hot plates, and the plates to be processed are This results in the heated plate colliding with the side surface of the heated plate or the treated plate body colliding with the side surface of the shelf.Furthermore, if the plate body itself is warped, there is a risk of colliding with each side as described above. In particular, when the board to be treated is temporarily bonded plywood, if the veneers making up the plywood are not aligned with each other at the four peripheral edges and are in a state where they easily peel off, one of the plywood sheets will If the part gets caught on the side of the hot plate and is bent, and if it is heated and pressurized as it is, a defective product will be ejected.

In view of the above, the present invention is a horizontal multi-stage press in which a plurality of hot plates are arranged side by side at equal intervals, and mounts are disposed on the loading and unloading side of the plate, and each mount is movable toward and away from the mount. The supported loader shelf and unloader shelf are intertwined at the front and rear ends of the hot plate to carry in the plate to be processed and carry out the processed plate. An example of this is shown in the attached drawing below. Based on this, we will first explain its configuration.

Frames 3 and 4 are installed on the left and right sides via a pair of upper and lower cross beams 1 and 2 arranged at arbitrary intervals in the vertical direction and the front and rear directions, and on rails 5 laid on the upper cross beams 1, The ram 10 of the fluid cylinder 9 installed on one of the frames 3 is attached to the back of the movable platen 7 by engaging the plurality of heat plates 6 and the moving members 8 protruding from both sides of the upper part of the movable platen 7. The heating plate 6 and movable platen 7 can be opened and closed.

An insertion guide 12 having a sharp tip and a substantially triangular cross section is formed on the side surface of each of the hot plates 6 on the side where the plate to be processed 11 is carried in. In addition, the brackets 13 attached near the four corners of the hot plate 6 and the movable plate 7 have
Gate-shaped cooling devices 14 are bridged to maintain equal spacing, and a supply port 15 is provided at the top of the hot plate 6, and a discharge port 16 is provided at the bottom for supplying and discharging the heating medium.

Furthermore, a pair of notch grooves 17 are bored in the lower part of the hot plate 6, and below the cutout grooves 17 there is provided a conveyor consisting of a plurality of rolls for carrying in and supporting the plate 11 to be processed and carrying out the processed plate 18. 19 is arranged on the machine frame 20 on the lower cross beam 2.

A roll at the tip of the conveyor 19 is supported between the arms 22 and interlocked with the stop member 21 .

Next, a push-up body 23 having a length of all stages of hot plates 6 capable of intervening in the notched groove 17 can be freely moved in and out of the conveyor surface of the conveyor 19 by means of a crank lever. Between 3 and 4, a pair of connecting beams 2
4 is arranged so that it can be raised and lowered by fluid movement, and this connecting beam 2
Push bodies 25 are attached to 4 at intervals of 6 hot plates when the press is opened.

Processed plate 11 of the horizontal multi-stage press 26 having the above configuration
A carry-in device 27 is installed on the carry-in side and on the processed board 18 carry-out side.
, and an unloading device 28 are arranged so as to be able to approach and separate in the direction of loading and unloading the plate, and the configuration thereof will be explained next.

On the loading and unloading sides of the horizontal multi-stage press 26, rails 30 with stoppers 29 arranged on the negative side are installed, although the horizontal multi-stage presses 26 are located close to each other, in order to regulate the distance at which they can be driven separately. and wheels 3 supported at the four corners.
On the other hand, on the other side of this rail 30, a chain drive by a motor and a rack and pinion drive are provided so that the frame 32 can freely approach and separate from the horizontal multi-stage press 26. , or as shown,
A fluid cylinder 33 for contact and separation is arranged, and this rod 34 is attached to the pedestal 32.

A pair of shafts 35 are supported on this pedestal 32 at arbitrary intervals, and a chain wheel 36 is fitted to both ends of this shaft 35, and a pulley 37 is fitted adjacent to the inside of the shaft 35. The belt 39 is suspended between the pulleys 37 of the chain 738, and an endless track is arranged so that the upper conveyance surface of the belt 39 is held slightly higher than that of the chain 738.

A frame member 41 is vertically fixed to the upper part of the attachment 40 constituting the pair of chess 738, and each pair of frame member 4
A loader shelf 43 or an unloader shelf 44 is constructed by connecting the two ends of the chain 7 with an intermediate member 42 that is perpendicular to the rotating direction of the chain 7.

At this time, a gap 45 is formed at the rear end of the loader shelf 43 in which the insertion guide 12 of the hot plate 6 is inserted, and a gap 45 is formed at the front end of the unloader shelf I at the rear end of the hot plate 6. A guide surface 47 that fits into the clearance 46 is formed.

Next, a regulating member such as a spacer or a roller is placed at the upper free end of the loader shelf 43 or the unloader shelf 44, that is, at a position that does not impede the loading, mounting, and unloading of the processed plates 11 and the processed plates 18. Attach the. In this embodiment, at the upper end of each frame member 41 constituting the loader shelf 43 or the unloader shelf 44, there is provided a spacer at the upper end of each frame member 41 that is the same as the left-right spacing of the hot plates 6, and in order to reduce the impact between adjacent ones. A spacer 48 to which an elastic body such as rubber is attached is attached.

Therefore, the loader shelf 43 or the unloader shelf 44 is supported so as to be able to rise and fall orthogonally to the board loading/unloading direction as the checker 738 rotates. Insert the plate 11 to be processed into the conveyor 50
In the carry-out device 28 , the processed plate 18 is taken out from between the unloader shelves 44 and transferred to the lift table 52 via the conveyor 51 .

Further, on the pedestal 32, an inlet conveyor 53 for carrying in the plate 11 to be processed or an ejecting conveyor 54 for carrying out the processed plate 18 is arranged so as to be able to move in and out of the upper conveyance surface of the belt 39 by fluid movement. The projection limit is set at the same height as the conveyor 19 of the horizontal multi-stage press 26.

In this embodiment, the loader shelf 43 or the unloader shelf 44 is supported by a chain 738 having an endless track so as to be able to rise and fall freely, but its lower end is supported on a frame parallel to the horizontal multi-stage press 26. It is also possible to use a supporting mechanism.

Next, the effect will be explained.

When heating and pressing the plate 11 to be processed in the horizontal multi-stage press 26, the carrying device 27 uses a checker 738 and a belt 39.
As the plate rotates, the plates 11 to be processed next to be heated and pressurized are inserted one by one between the loader shelves 43 from the top of the lifting platform 49,
By supporting the lower end of the loader shelf 43 on the belt 39, the loader shelves 43 are sequentially raised and loaded with full load.

In addition, in the unloading device 28, a check/38, a belt 3
9, the processed plate 18 that has been carried out first is loaded from the take-out conveyor 51 onto the lifting platform 52 while supporting its lower end on the belt 39, and the processed plate 18 is stacked between the unloader shelves 44. The body 18 is transferred.

After the heating and pressurization is completed and the press is opened, the intervals between the loader shelf 43, the hot plate 6, and the unloader shelf 44 become the same. At this time, the approaching/separating fluid cylinder 33 is operated, and the rod 3
4, each frame 32 runs on the rail 30 as shown in the chain double-dashed line in FIG. 1 or as shown in FIG.
The cavities 45 of each loader shelf 43 approach each other in the direction of 6.
The insertion guides 12 of each hot plate 6, the clearance portion 46 of each hot plate 6, and the guide surface 47 of each unloader shelf 44 intertwine with each other and become linked.

Under this condition, the push-up body 23 is lowered and retracted to transfer the processed plate 18 onto the conveyor 19, and at the same time, the carry-in conveyor 53 and the carry-out conveyor 54 are made to protrude from the belt 39 surface, so that the conveyance surfaces are the same, and each conveyor 19, 53
, 54, the processed plate 18 is reliably carried in and out from between the hot plates 6 to between the unloader shelves 44, and the processed plate 11 is reliably carried in and out from between the loader shelves 43 to between the hot plates 6. .

Next, when the rod 34 is extended by reverse operation of the moving/separating fluid cylinder 33, the linked state is released.

Thereafter, the horizontal multistage press 26 is closed to heat and press the loaded plate 11 to be processed, and the loading device 27 and the loading device 28 stand by in preparation for the next operation as described above.

As described above, according to the apparatus of the present invention, frames are disposed on the plate loading/unloading side of a horizontal multi-stage press consisting of a plurality of hot plates arranged at regular intervals, and can be moved toward and away from each other. The loader shelf and unloader shelf supported by each frame are intertwined with the front and rear ends of the hot plate and are interconnected to carry in the plate to be processed and carry out the processed plate, so that the process as described above is carried out. , it is possible to avoid collisions of processed plates with the side of the hot plate or of processed plates with the side of the unloader shelf, discharge of defective products, etc.
