Abstract

PURPOSE:To enable a waiting action of veneers to maintain an appropriate space among them on a conveyor so as to augment the packing efficiency to a multi-step roll drier by arranging a pooling device other than a perpendicular direction delivery device after unspecified length of the veneers on the conveyor has been cut. CONSTITUTION:A detecting device PH1 located on a forwarding conveyor 1 which conveys unspecified length of veneers at a given interval, detects the space among the veneers at all time allowing a transversal conveyor 2 to be actuated or be suspended so as to allow the veneer to come extremely close together permitting them to be cut by means of cutting devices 3A and 3B. Then, the cut veneers are transferred to a delivery conveyor 5 which is perpendicular to the above said conveyor, and then are forwarded to each step of a multi-step roll drier. Here, depending on the situation, the cut veneers are kept waiting at either said of a rear reverse rotation device 6, a pooling conveyor 15, and a front reverse rotation device 16, allowing the weiting veneers to return to the transversal conveyor so that each of the detecting devices PH allows the veneers on the transversal conveyor 2 to be spaced with the stated space apart. This operation enables the packing effect to be augmented.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for conveying a veneer veneer to an auto feeder of a multi-stage roll dryer.

Conventionally, a multi-stage low M dryer was created by inserting several pieces of parallel plywood veneer (hereinafter simply referred to as veneer) into the conveyor of the auto feeder, which workers commute directly to work at regular intervals. It was sent to each stage.

However, in recent years, with the depletion of rainwater timber, the number of long veneers obtained from low-grade logs has been decreasing, and as a result, short veneers with defective parts removed have become available. Therefore, when the operator inserts these veneers into the auto feeder, the short veneers may not be able to be inserted, and the veneers may be sent to the multi-stage roll dryer in a state that is less than one load as described above. This resulted in a decrease in the filling efficiency of the multi-stage roll dryer.

The present invention has been developed to address the above-mentioned disadvantages, and as a result, it is an attempt to improve the light filling effect of a multi-stage roll dryer.

The veneers of unspecified length that are pushed into the incoming conveyor at arbitrary intervals are transferred to the next stage cross conveyor iCj? At the same time, the steel is cut at a constant cycle by a pair of cutting devices installed side by side at a predetermined interval, and then the steel is taken out in a direction perpendicular to the cutting device. The veneers are stored in the front reversing device and pooling conveyor installed above the traverse conveyor, and when the interval between the veneers inserted into the feed conveyor becomes larger than a predetermined value, the stored veneers are This method replenishes the veneer by returning the veneer from the front reversing device to the transverse conveyor.

The present invention will be explained below with reference to the accompanying drawings.

FIG. 1 is a side layout diagram showing an embodiment of an apparatus for carrying out the method of the present invention. Reference numeral 1 denotes a feeding conveyor to which detection devices PH1 and PH2 are attached, and in particular, detection device PH1 constantly measures the distance between the veneers that are successively inserted.

is a detection device.

Following the rear reversing device 6, a pooling conveyor 15 consisting of a first endless belt 12, a second endless belt 18, and an eighth endless belt 14 is provided above the transverse conveyor 2C/).
4. PH8 and PHa are detected by the detection device.

Reference numeral 16 denotes a front reversing device constructed almost similarly to the rear reversing device 6;
In addition, the discharge side thereof is connected to a traverse conveyor 2. PH1 is a test! 1 device.

Next, its effect will be explained.

The veneers p+, P2, P8, etc. of unspecified length are inserted into the feeding conveyor 1 at arbitrary intervals as shown in FIG. be measured. As a result, assuming that this interval is within a predetermined range, the preceding veneer P1 is detected by the next detecting device PH2. At this time, the detecting device PH8 of the front reversing device 16 is turned on and off. Irrespective of this, the conveyor 2 is transported to the traverse conveyor 2 in the raised position shown by the solid line in FIG. Then, when the detection device PH8 on the carry-in side detects the rear end of the preceding veneer PI, the clutch brake (not shown) of the drive device of the transverse transfer conveyor 2 and the rear reversing device 6 is activated.
The preceding veneer P1 is then temporarily stopped. Further, the veneer P2 following the live conveyor 1 is carried into the traverse conveyor 2 which is activated again by the number M detected by the detection device PH2 located at the rear. Then, in the same way as above, the clutch brake (not shown) of the drive device of the ram feed conveyor 2 and the rear reversing device 6 cuts off the drive again in response to a signal that the detection device PH8 detects the rear end of the following veneer P2. The plate P2 is temporarily stopped. Therefore, due to this intermittent driving of the traverse conveyor 2, the preceding veneer P1 and the following veneer P2 are brought together in a very close state. Veneer Pa, p4, carried to conveyor 2...
. . . are controlled in a coordinated manner, and the rear reversing device 6 is temporarily stopped at the position shown in FIG. 4, for example, in response to a signal of a constant period. On the other hand, the veneers P8 and P9 on the feed conveyor 1 continue to be conveyed and when the detection device PH2 is turned on, the feed conveyor 1 stops and becomes temporarily in a standby state.

During this time, the veneer P ff1-P on the transverse conveyor 9 conveyor 2?
are cut at predetermined intervals by the cutting devices 3A and 3B, and then the traversal conveyor 2 is lowered to the position shown by the two points shown in the figure. direction, and is sent to each stage of a multi-stage roll dryer (1, omitted in the figure) via a carry-in conveyor (i, omitted in the figure) t-, which swings at a constant cycle of the auto feeder.

On the other hand, the veneers PI and P! remained in the rear reversing device 6! '(
P! After the cutting devices 8A and 8B have cut the remaining material, the rear reversing device 6 is turned on again to turn on the cutting device PHf. At this time, if the detection device PH6 of the third endless band 14 located before and after is OFF, the eighth endless band 14 is activated and the veneers P1 and PHI turn on the detection device PHI. Similarly, under the condition that the preceding detection devices PH6, PH4, and PHI are OFF, the veneers PI and PHI are sequentially conveyed to the front reversing device 16 across the two endless bands 13, and are in the state shown in FIG. become.

Furthermore, the veneers P9 to p1 were carried to the transverse conveyor 9 conveyor 2.
M is similarly cut to a predetermined length and then transported in a direction perpendicular to the number 7. In addition, the veneers Pte/, P8, Ps' (remaining material after cutting ps) remaining in the rear reversing device [16] are removed from the rear reversing device 6, which is restarted after cutting by the cutting devices 3A and 3B described above.
It is conveyed to the lower side one after another, and is detected by the detection device PH4 of the first endless band 12. However, at this time, since the detection device PHI of the front reversing device 16 at the previous stage is turned on, the front reversing device 16 is not activated and the veneer Pγ′, pa
, ps are temporarily placed on standby on the first endless band 12 shown by the two-dot chain line in FIG. Thereafter, in the same manner, the veneer P remaining in the rear reversing device 6 each time is transported to the second endless #
The data are stored sequentially from 18 onwards. As a result, in rare cases, a fully loaded state as shown in FIG. 7 occurs in which the veneers P are stored up to the rear reversing device 6, and all the detection devices PHI to PHf are turned ON.

In this case, once the veneers Pa and Pb in the waiting state on the feeding conveyor 1 and the veneer conveyor 2 and the rear vomiting table 1!6 that are pushed in are broken down, the veneer conveyor 1 and the rear vomiting table 1! They are carried into the conveyor 2 and conveyed in an assembled state. And as described above
- When the preceding veneer Pa is detected by the detection device PHs, which can be detected only when all Pays are ON, these veneers Pa, Pb, Pc, Pd... , and are cut by the cutting devices 3A and 3B and carried out toward the auto feeder in the perpendicular direction.

As already mentioned, the intervals between the veneers P that are sequentially carried into the feed conveyor 1 are constantly measured via the detection device PH1. Under the condition that this interval is larger than a predetermined value, the veneer P that has been kept on standby after the front reversing device 16 can be returned to the bond feeding conveyor 2 and replenished. This will be explained below.

Veneer PI% waiting in the front reversing device 16 in Fig. 5
F! A time T for starting the conveyance of the ' to the traverse conveyor 2 is appropriately set in advance.

When the feed conveyor 1 is started, the detection devices P and l (l detects the rear end of the preceding veneer P16 and turns OFF), then detects the curved end of the following veneer pLy and turns ON. By detecting the time tt, the distance between the veneers P being inserted into the feeding conveyor 1 is constantly measured. As a result, under the condition that the time of the subsequent veneer p1y and the set time T are t)T, the veneers Pl, pg/, pt', pa, p on the front reversing device 16 and the first endless band 12 are s/ is set to the next detecting device PH* f OF F after T1 time after the rear end of the preceding veneer p r i passes through the detecting device PH1. The front reversing device 6 and the first
The endless belt 12 is activated at the same time, and the single plates P1, P2',
P1', P8, p s / are returned to the transverse 9 conveyor 2 as shown in FIG. 6, and are conveyed in an assembled state.

is detected and paused. Then, the detection device PH8 of the front reversing device 16 detects the rear end of the veneer P2' on its way back to the above-mentioned lateral conveyor 2 -'j, and the feed conveyor 1 is started again and placed on standby. Said veneer Pji inside, pr8
. . . are sequentially conveyed to the traverse conveyor 2. During this time, the front reversing device 16 is followed by the veneer P? /, Pa, p
When the front end of the veneer P7' located in the front position is detected by the detection device PH8, the e/ is once again in a standby state in preparation for returning to the next traverse conveyor 2.

Although the Guhring conveyor is constructed of an endless belt, it may be replaced with a roller conveyor.Furthermore, in the present example, the Guhring conveyor was explained as being divided into three sections, but this may be replaced with a roller conveyor. It is not limited, and is appropriately determined depending on the drying capacity of the multi-stage roll dryer, the dimensions of the veneer, etc. Further, the detection device is a phototube device according to the symbol PH, but it may also be a limit switch, a microsinch, or the like. Further, the interval between veneers inserted into the feeding conveyor can be measured using a combination of the above-mentioned detection device with a timer, a pulse counter, etc.

The non-invention is that since the VTC configuration is different from the above, the table plates t with the unloaded foot length δ inserted at arbitrary intervals are assembled on the transverse transfer conveyor, and at the same time, one load of the auto feeder's carry-in conveyor is After cutting the intersecting veneer, it can be carried out in the right angle direction.

On the other hand, if the insertion of the veneer into the feed conveyor is temporarily interrupted due to an accident, or if a short veneer is temporarily shifted to one side, the operator may be unable to load one load of the auto feeder. This one within a given time as the frequency of insertion increases.
When the gap between adjacent veneers becomes larger than a predetermined value due to the inability to insert the loaded amount, the waiting veneers stored in the front reversing device and pooling conveyor are returned to the traverse conveyor. You can replenish it by letting it go. Therefore, according to the present invention, the veneers carried in are assembled on the transverse conveyor, the veneers for one load of the auto feeder are secured, and then carried out to the auto feeder in the perpendicular direction. The filling efficiency of the multi-stage roll dryer can be significantly improved.
