ある。 Conventionally, when processing veneer veneers (hereinafter simply referred to as veneers) in the process of manufacturing plywood, for example, the stripping process using veneer lace and the drying process using a continuous dryer are usually continuous operations, and the veneer is continuously processed. On the other hand, the cutting process with a clipper and the joining process with a horizontal hooking machine are usually intermittent operations, and the veneer is processed intermittently, and the process of inserting the veneer into a roll dryer, etc. Although it may result in intermittent processing due to changes in the transport direction, etc., differences in the processing form in each process will inevitably cause differences in the short-term processing speed of the veneer. Even if the processes have substantially the same processing speed based on the actual operating rate, etc., simply connecting them using a conveyor, etc. will prevent veneer breakage and clogging caused by short-term differences in processing speed. It is not possible to prevent such problems, and the current situation is that each process is separated and an irrational process is carried out in which deposition and removal are repeated using a huge number of people, deposition equipment, locations, etc.

The purpose is to enable the connection of processes with different processing speeds, thereby streamlining the veneer processing process at a plywood factory.

て大幅に合理化する事ができる。 The veneer processing apparatus according to the present invention is configured, for example, as described above, and includes a transport member, such as an appropriate number of pulleys (not shown) fitted to the shaft 1, from the previous process (on the right side in the figure). ) When the veneer 7 carried in by an appropriate number of conveyor belts 9 reaches the lower position of the pressing pulley 6, it pierces the piercing body 4 of the chain 3 by the pressure of the pressing pulley 6. Then, after being conveyed following the hanging of the chain 3, the conveyor belt 8 sequentially peels off the piercing body 4 and conveys it to a subsequent process (on the left side in the figure). For example, a chain 3 as shown in the figure
Figure 2 shows an example of a situation in which the processing speeds of the front and rear processes were kept balanced in a drooping state, but if the processing speed of the rear process increased compared to the processing speed of the front process. As shown in Figure 3, if the upper side of the chain 3 rises to automatically buffer the difference in processing speed, and conversely the processing speed of the subsequent process decreases compared to the processing speed of the previous process, the chain 3 will rise as shown in Figure 3. The upper part of 3 descends to automatically buffer differences in processing speed, making it possible to connect front and back processes that have different short-term processing speeds without any hindrance, making it ideal for plywood factories. The veneer processing process can be significantly streamlined compared to conventional methods.

んど差支えない。 The rotation of the pair of rotating bodies may be driven by a drive mechanism (not shown) such as a motor or clutch brake that operates in synchronization with the processing speed of each process, or by the power from each process. It may be a driven type by transmission, for example, a driven type via conveyor belts 8, 9 or a pressing shaft and pressing pulley 6. Further, as will be described later, if the rotation of the rotating body on the front process side is made into a multi-rotational type via a drive buffer member or the like, it is convenient when narrow width veneers are processed intensively. That is, for example, a rotating body on the front process side (shaft 1 and chain wheel 2 in the embodiment illustrated in FIG. 1), a drive member (not shown) that drives the rotating body, or a conveyor that is a loading member in the front process. For example, a one-way clutch or
If the rotation of the rotating body on the front process side is made into a multi-rotation system in which mutual drives can be superimposed by interposing a drive buffer member such as a torque limiter, even if the processing speed of the downstream process is lower than the processing speed of the front process, As illustrated in FIG. 2, the processing speed of chain 3 increases.
Even if the upper side rises and reaches the upper limit and becomes tense, the rotating body ( In the embodiment illustrated in FIG. 1, even if the shaft 1a and the chain wheel 2a) are rotated to cause the chain 3, which is a veneer conveyor, to rotate, the distance between the narrow veneers being conveyed increases. There is almost no difference in practical use.

止できるようにするのが望ましい。 However, when processing a relatively long veneer or a continuous veneer, if the upper part of the chain 3 reaches its upper limit and is in a tensioned state, if it continues to rotate, the difference in processing speed will result. As a result, a tensile force is applied to the veneer and the veneer breaks, so for example, as shown in FIG. The structure is configured such that it can detect that the buffering limit has been reached by means such as providing an upper limit position detector 10, and based on the detection signal, the processing of the veneer in the subsequent process is not artificially performed. Alternatively, the processing of the veneer in the post-process may be automatically temporarily stopped or decelerated based on the detection signal, or a clipper may be provided during the pre-process, although not shown. Preferably, the clipper is configured to be able to cut the veneer by operating the clipper based on the detection signal, so that breakage of the veneer due to the difference in processing speed can be prevented. Even when the processing speed of the subsequent process decreases compared to the processing speed of the previous process, and the upper side of the chain 3 descends as illustrated in FIG. 3 and reaches the lower limit, as illustrated in FIG. A lower limit position detector 11 such as a limit switch or a photoelectric switch is provided near the lower limit position on the upper side of the chain 3, so that it can be detected that the buffering limit has been reached. Based on the detection signal, the processing of the veneer in the previous process is artificially stopped temporarily, or the processing of the veneer in the previous process is automatically temporarily stopped or decelerated based on the detection signal. It is desirable to configure the system so that clogging of the veneer due to the difference in processing speed can be prevented.

2. A conveyor consisting of a conveyor shaft 23 and the like. In this embodiment, as in the previous embodiment, for example, if the processing speed of the subsequent process increases compared to the processing speed of the previous process, the upper side of the toothed belt 13 rises to buffer the difference in processing speed. However, if the processing speed of the subsequent process decreases compared to the processing speed of the previous process, the upper side of the toothed belt 13 will descend to buffer the difference in processing speed, but the toothed belt, i.e. By hanging the veneer conveyor in multiple stages, it is easy to increase the buffering capacity in a relatively small space. Differences in processing speed can be buffered.

い。 In addition, as a means for making the veneer transport body hang smoothly over multiple stages, for example, as shown in FIG.・Feeding detector 1 for photoelectric switches, etc.
9 is provided, and until the feed-out detector 19 detects the lowering of the upper side of the toothed belt 13, the drive mechanism 20, such as a motor/clutch brake, etc. is operated to continuously operate the belt at an arbitrary speed. Various means can be used, such as means configured to drive the feed roll 18 so that the toothed belt 13 always hangs from the downstream side, and means for forcibly hanging the toothed belt 13 using a movable pulley-like tier roll or the like as described later. However, in any case, similarly to the embodiment illustrated in FIG. 1, if the rotation of the rotating body on the front process side is made into a multi-rotational type via a drive buffer member etc.,
This is effective when processing small width veneers intensively, and on the other hand, when processing relatively long veneers or continuous veneers, an upper limit position detector 10 and a lower limit position detector 11 may be provided. It is desirable to be able to detect that the damping limit has been reached, and to prevent breakage or clogging of the veneer due to the difference in processing speed based on the detection signal.

違を緩衝する事ができる。 The embodiment illustrated in FIG. 5 also has a veneer conveyor suspended in multiple stages. In the figure, 24 and 24a are rotating rolls which are other embodiments of the rotating body, and 25 is a veneer conveyor. 26 is a flat belt which is another embodiment of the veneer pressing member; 27 is a fixed peeling bar which is another embodiment of the veneer peeling member; 28 is a flat belt which is another embodiment of the veneer pressing member; is flat belt 25
29 is a tension roll of the flat belt 25, 30 is a tier roll of the flat belt 25,
31, 31a and 31b are weights, 32 is weight 3
Stoppers 1, 31a, and 31b, and 33 are idle rolls. In this embodiment as well, the difference in processing speed between the preceding process and the subsequent process is buffered by raising and lowering the upper side of the flat belt 25, which is a veneer conveyor. In order to make the material hang down smoothly, a forced hanging means such as a tier roll is used. That is, for example, as illustrated in FIG.
By attaching weights 31, 31a, and 31b to 0, and providing a difference in weight between each of the weights 31, 31a, and 31b, for example, 31>31a>31b, the processing speed between the preceding and following processes can be increased. If the upper side of the flat belt 25 rises due to the difference in
Next, the tiner roll 30 with the weight 31a attached rises, finally the tiner roll 30 with the weight 31 attached rises, and finally the tiner roll 30 with the weight 31 attached rises. Conversely, when the upper side of the flat belt 25 is lowered, first the tier roll 30 attached with the weight 31 is lowered, then the tier roll 30 attached with the weight 31a is lowered, and finally the tier roll 30 attached with the weight 31b is lowered. 30 descends. Along with the automatic lifting and lowering of each tier roll as described above, the upper side of the flat belt 25 also rotates while lifting and lowering automatically, so there is no stagnation during conveyance, and the hanging over multiple stages makes it relatively smooth. It is possible to buffer the short-term difference in processing speed between the long-term pre-process and post-process.

が望ましい。 The order in which the tiner rolls are raised and lowered is not limited to the above-mentioned order, but may be reversed or in a different order.Instead of attaching a weight, it is possible to set a difference in the weight of each tiner roll. However, if the veneer processing in the post-process is intermittent, the weight of the tier roll and weight may be reduced in order to reduce the inertial resistance when the veneer conveyor is rotated. It is preferable to make the weight as light as possible,
If necessary, it is desirable to support the tyner roll using a support member such as a tension spring, a pulley, or a weight to reduce inertial resistance during the ascent.

事も、前記実施例の場合と同様に可能である。 In all of the above embodiments, the upper side of the veneer conveyor is made to hang down by utilizing its own weight, etc.
Since plywood factories have relatively high ceilings, for example, as in the embodiment illustrated in FIG. The tension member is configured to be completely supported using a support member such as a pulley 36 or a tension spring/fluid cylinder (not shown), so that the upper side of the veneer conveyor can be lightly pushed upward, There is no problem in automatically buffering the difference in veneer processing speed between the front process and the back process, and if necessary, it is also possible to push up the veneer in multiple stages by installing turning rolls, etc. This is possible in the same way as in the previous embodiment.

る部材であれば差支えない。 In addition, each member such as the rotating body, veneer conveyor, veneer peeling member, veneer pressing member, etc. in each of the above-mentioned embodiments can be replaced with those of other embodiments. It is also possible to replace it with another shape or form that has a similar effect, and it is not necessarily necessary to select the optimal combination. That is, for example, for the engagement between the rotating body and the veneer conveyor, from the viewpoint of reliably preventing slippage, it is preferable to engage by meshing, such as between a chain and a chain wheel, or a toothed belt and a spline shaft, but a flat belt Even if the engagement is based on friction, such as between a rotating roll or a flat belt and a rotating pulley, there is no practical problem or is necessary as long as consideration is given to the coefficient of friction, wrapping angle, tension, etc. to prevent large slippage. Figures 5 and 6 depending on
As illustrated in the figure, it is also effective to apply a pressing force by attaching an idling roll or the like, and for example, a combination such as a flat belt and a spline shaft may be used in practice. In addition, the piercing body of the veneer conveyor may be needle-shaped or
Various shapes such as mushroom-shaped, pyramid-shaped, and conical shapes can be mentioned, but the point is that any shape that can easily pierce the veneer, be difficult to pull out, and not leave a puncture wound will do. In addition, when piercing a veneer with the piercing body, the spacing between the tips of adjacent piercing bodies changes between the arc-shaped portion and the straight-line portion of the veneer transport body, so the relatively thick Since there is a risk that the veneer, etc. may bulge and fall out, it is effective and necessary to take measures to prevent the veneer from falling out, such as by running the veneer conveyor in a straight line or in a reversely curved manner while piercing. Depending on the length (height) of the piercing body
The thickness of the veneer should be several times the thickness of the veneer, and the veneer should be pierced near the tip to provide enough room for the veneer to bend in a wavy manner, or the base material, i.e., the veneer conveyor, should be made elastic, such as a rubber belt. It is desirable to take care to prevent the veneer from coming off as a flexible member, and it is also effective to impart elasticity to the veneer by subjecting it to a tenderizing process. Furthermore, the number and width of the veneer conveyor, the pitch at which the pierced bodies are arranged, etc. may be appropriately selected depending on the thickness, shape, etc. of the veneer to be processed. In addition, the veneer pressing member is preferably a rotating member such as a pressing shaft, a pressing pulley, or a pressing roll, but even if it is a non-rotating type such as a leaf spring-shaped pressing bar, the friction coefficient, approach angle, etc. should be considered. There is no problem as long as care is taken to allow the veneer to slide smoothly.In short, any member that can be pressed so that the veneer can be properly pierced by the piercing body of the veneer transporter can be used. Also, as for the veneer stripping member, it is preferable to use a traveling type member such as a conveyor belt or a large-diameter roll, but even if it is a non-travelling type member such as a fixed type stripping bar, it is possible to remove the veneer by considering the friction coefficient, approach angle, etc. There is no problem as long as care is taken so that the veneer can slide smoothly.In short, there is no problem as long as the veneer can be properly peeled off from the piercing body of the veneer conveyor.

構成の方が望ましい。 For example, as in the embodiment illustrated in FIG. 7, the veneer is inserted into the lower side of the veneer conveyor, and the length of the conveyance process expands and contracts as the lower side of the veneer conveyor rises and lowers. Although it is possible to buffer the short-term difference in processing speed between the process and the subsequent process, there is always the inherent risk that the veneer will slip out of the piercing body and fall. It is preferable to have a configuration in which the veneer is stuck on the upper side of the veneer conveyor, as in each of the embodiments described above, to reliably prevent at least the veneer from falling.

めて多大である。 As is clear from the above, the apparatus of the present invention has a veneer conveying body for pricking and conveying veneers that is loosely rotated in a pair of rotating pairs, and the length of the conveying process of the veneer expands and contracts as the conveyor moves up and down. It is designed to buffer the difference in short-term processing speed between the process and the subsequent process. Of course, it is possible to connect a continuous pre-process and an intermittent post-process, such as a clipper and a continuous dryer, or a horizontal hooking machine and a veneer winder, etc.
It is also possible to connect an intermittent pre-process and a continuous post-process, and also to connect an intermittent pre-process and an intermittent post-process, such as an automatic insertion device between a clipper and a horizontal hooking machine or a clipper and a roll dryer. Moreover, it is possible to process veneers of all thicknesses and shapes, from discontinuous narrow veneers to continuous veneers.
The veneer processing process can be significantly streamlined compared to the conventional method, and the effects of implementing the present invention in plywood factories are extremely large.
