Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the configuration of an apparatus for automatically producing fragrant wood incense sticks.

More specifically, the present invention is an apparatus for manufacturing fragrant wood incense sticks that is equipped with a body cutting device that automatically cuts raw incense sticks grown on a drying board into pieces of a certain size during transportation.

Traditionally, the production of incense sticks has been a manual process because the objects to be processed are extremely fine and soft, and a large number of incense sticks must be processed at all times. In other words, the manufacturing process according to the conventional method consists of processing the powdered raw material into water-kneaded lumps, forming the same into a plurality of linear objects using an extruder, and taking out the sagging pieces on a tray, and drying. In order to prevent polarization, the raw incense sticks taken out in this way are transferred from the tray board to the drying board (the 9th stage).
As shown in the figure and FIG. 10, a wooden board ruler F is pressed against the raw incense stick B grown on the drying board A, and the raw incense stick is cut along the side edge of the wooden board ruler using the manual disc cutter G. The raw incense stick is then air-dried on a drying board A. The drying method in this case is to support the vertical walls a, a provided at both edges of the drying plate A in contact with the front or back surfaces of the vertically adjacent drying plates, respectively, as shown in FIG. By means of a device in which a gap a' is formed by... A large amount of raw incense sticks is dried using this drying method. The dried incense sticks are bundled into units and packaged to produce products.

Note that the disk cutter conventionally used in the above-mentioned body cutting process has a rounded cutting edge. This shape of the cutting edge was adopted to prevent danger during manual work or damage to the wooden board ruler F itself, and it was impossible to sharpen it. When such a disk cutter is used, cutting is performed by moving and deforming the cutter by pressing. Therefore, the cut end c' of the shredded raw incense stick b' often suffers from bending deformation e as well as chisel blade shape deformation d'.

In addition, when the disc cutter G is manually operated, as shown in Fig. 10, it requires considerable skill to always keep the disc cutter G perpendicular to the side edge of the wooden board ruler F. If the cutter G' is even slightly tilted, the cutting position relative to the fresh incense stick will be significantly shifted. Due to this misalignment of the cutting position, the lengths of the product incense sticks will not be the same.

Furthermore, delays in this manual process of cutting the body tend to delay the incense process, resulting in uneven drying of the raw incense sticks, and as a result, the incense sticks themselves become bent. The purpose of the present invention is to eliminate the drawbacks of the above-mentioned conventional methods, and to automate the entire manufacturing process by automating the body cutting process, thereby providing an apparatus that can quickly manufacture regular-shaped product incense sticks. That is.

In order to achieve this objective, the following configuration is adopted in the present invention regarding an apparatus for manufacturing fragrant wood incense sticks.

That is, it has a conveyor that transports a drying plate on which a large number of raw incense sticks are grown in parallel, in a direction perpendicular to the longitudinal direction of each of the raw incense sticks, and the surface of the drying plate that is transported by this conveyor is A disc-shaped blade having a cutting edge with an apex angle of 12° to 18° is always vertically in contact with the conveyor, is rotatable along the conveying direction of the conveyor, is movable in the vertical direction, and is constantly coated with a mold release agent. The present invention is characterized in that a plurality of cutters are sequentially arranged at regular intervals in the width direction of the conveyor, each under a constant weight at a position above the drying plate surface.

The present invention operates as follows.

The loading configuration for the disc-shaped cutter is such that the cutting edge is vertically in contact with the drying board surface, and the disc-shaped cutter is movable in the vertical direction.
To automatically obtain the rotation of a disc-shaped cutter from the operation of a conveyor, and to ensure cutting of fresh incense sticks. In addition, the sharp shape of the disc-shaped cutter blade makes it possible to quickly cut the raw incense sticks on the drying board without causing any deformation due to the coating structure of the release agent and dust. At the same time, when cutting the bodies, the arrangement of each raw incense stick is not disturbed due to the rotational movement of the disc-shaped cutter and dust.

Next, examples of the present invention will be described.

An automatic incense stick manufacturing apparatus according to an embodiment is shown in a side view and a plan view in FIGS. 1 and 2.

This automatic incense stick manufacturing device has guide rails 32, 32 that are parallel to each other along the transfer direction between frames 3, 3 installed on the foundation, and the ends of each guide rail 32 are opposite to each other. frame 3,
A guide wheel 3 rotatably supported at 3
3, 33' are disposed, and two conveyor chains 35 are disposed in parallel, supported and guided by the guide rail 32, and circulate between the guide wheels 33, 33'.
Conveyor bars 36 arranged at regular intervals to 5
A conveyor 2 has a configuration in which... are suspended over a rack, and this conveyor 2 consists of a motor wheel 3 fixed to the end of a rotating shaft of a conveyor drive motor 37 below a frame 3.
8 to the guide wheel 3 via the transmission belt 39
The rotating operation is performed by transmitting power to the transmission wheel 33'' at the end of the 3' axis.

Next, as shown in FIGS. 3 and 4, the body cutting device 1 has a bridge 4 fixed on frames 3, 3 in a state that straddles the transfer surface of the conveyor 2. has a shaft 13 that is rotatably supported in the transfer direction, and three holders 12 are loosely fitted at appropriate positions on the shaft 13 and are locked by collars 14 so as to be able to swing freely. A support arm 8 is provided, which is screwed to a bearing 6 having each end formed in the vertical direction.
Further, a disc-shaped cutter 5 is vertically supported by a support shaft 7 at the lower end of each bearing 6 of each of these support arms 8 so as to be rotatable along the conveyance direction of the conveyor 2. At the tip, a parting roller 9 is circumscribed to the disc-shaped cutter 5 and rotatably supported by a support shaft 10, and automatically and continuously applies a mold release agent such as silicone oil onto the surface of the disc-shaped cutter 5. be able to.

Further, a weight 11 is pivotally attached to the upper part of each support arm 8 so as to apply constant pressure vertically downward at all times.

Further, a gear 17 is disposed at the extreme end of the shaft 13 that extends outside the bridge 4, and this gear 17
It meshes with a gear 18 fixed to the end of the rotating shaft supported by a bearing 23 at the upper part of the bridge 4.
A swinging lever 22 is connected to the other end of the rotating shaft, and a contact roller 21 is attached to the end of the lever 22.
is rotatably supported. This contact roller 2
1 constantly pushes a cam wheel 20 disposed on the rotating shaft of a cam drive motor 19 mounted on the upper part of the bridge 4. Therefore, when the cam wheel 20 rotates once, the lever 22 swings and rotates the shaft 13 via the gears 18 and 17.

In addition, a brush drive motor 2 is mounted on the top of the bridge 4.
6 is mounted, and a gear 27 is arranged at the end of its rotation shaft. A gear 28 on a rotating shaft supported by a coupling ring 29 meshes with this gear 27 .

As shown in FIGS. 1 and 2, flexible shafts 30 are connected to the rotating shaft supported by the above-mentioned coupling ring 29, respectively, from both ends thereof. A brush 31 is connected and supported on the frame 3.

Therefore, the brush 31 is rotated by the power of the brush drive motor 26 via the gear 27, the gear 28, the rotating shaft, and the flexible shaft 30, respectively. When the brush 31 rotates, it acts to sweep the cut end of the shredded raw incense stick downward.

In addition, the cutter lifting lever 15, which is held on the shaft 13 and communicates between the lever arms 16, 16 protruding in the transfer direction, is parallel to the shaft 13 and simultaneously contacts each support arm 8 from below. It is placed in a location where it is possible. Therefore, as the shaft 13 rotates based on the drive of the motor 19, the lever 15 swings up and down to raise and lower each cutter 5 via each support arm 8.

The purpose of this vertical movement of the cutter 5 is to avoid collision with the vertical wall a at the front of the drying plate A which is being transported on the conveyor 2.

Each support arm 8..., as shown in FIG. The pressure applied to the shaped cutter 5 can be adjusted. Note that this pressing force can also be achieved by replacing the weight 11 itself.

The disk-shaped cutters 5 in this loaded state are swingable with respect to the shaft 13 via the support arms 8, and as shown in FIG. Even if this plate surface is not completely smooth, the cutting edges are always in contact with each other in a perpendicular state. This causes contact resistance, and rotation in the direction of arrow A is obtained in accordance with this drying plate.

By the rotation of each of the disc-shaped cutters 5, the end portions of the raw incense sticks B arranged in a column on the surface of the drying plate A are cut to a fixed size without disturbing their arrangement.

In addition, in front of the bridge 4, a limit switch 25 is disposed on the frame 3 and has an arm with which the vertical wall a comes into contact when the drying plate A placed on the conveyor bar 36 of the conveyor 2 and being transferred advances. Become. When the limit switch 25 is turned on, the motor 19 is driven.

Further, the cut ends of the raw incense sticks that have been cut into bodies fall into a hopper 40 arranged below the frame 3.
This hopper 40 has screw blades 41' inside.
The conveyor 2 has a screw 41 which is fixedly fixed in a spiral manner and is rotatably disposed in the side direction of the conveyor 2. This screw 41 has a screw wheel 42 at its end, a conduction chain 43 and a motor wheel 4.
4 and is rotated by the power of a drive motor 45. As the screw 41 rotates, the cut ends of the raw incense sticks in the hopper 40 are re-kneaded and compressed while being pushed out in the direction of the screw axis and reused.

In addition, in the process of transferring the dry plate that has been grown on the conveyor 2 before the body cutting process, the correction of the deviation of the dry plate on the conveyor 2 and its positioning are carried out in the sixth step.
As shown in the figure, a cam lever 46 is rotatably supported on an upper end of each frame 3 in a horizontal plane. That is, the leading end of the drying plate A introduced onto the conveyor 2 is positioned by making the tip end of each cam lever 46 come into contact with the rear standing wall a of the drying plate A in a downward position. In this case, the tip portion rotates outward and each cam lever 46 does not come into contact with the fresh incense stick end. Further, as shown in FIG. 7, plate-shaped position holding claws 49 are provided at both ends of the conveyor bar 36 to protrude in the traveling direction, and the vertical wall a of the positioned drying plate A is moved upward onto the conveyor bar 36. Fixed to. Further, guide bars 47, 47 each having an expanded tip are provided above the conveyor chain 35 and supported by U-shaped support arms 48 fixed on each frame 3 along the transport direction. By abutting each of these guide bars 47 with the end of the vertical wall a in the upward position, it is possible to correct the deviation and position the drying plate A with respect to the rear thereof.

In the above-mentioned body cutting device 1, the disc-shaped cutter 5 has a diameter of 50 mm, a thickness of 0.8 mm, and a blade apex angle of 15 degrees, and the weight 11 is loaded with 500 g to cut the body with a cross-sectional diameter of 2.0 mm. As a result of operating the device to transport drying plate A with a considerable number of incense sticks on it at a speed of 7.5 m/min,
A considerable number of shredded raw incense sticks with uniform length and no bending were obtained, and as shown in Fig. 5, shredded raw incense sticks b
The cut end c had a smooth surface with only a chisel-blade-shaped protrusion d. The presence of the protrusions d does not pose an obstacle when processing into a unit number of incense stick bundles, and also has the effect of improving ignition.

If the apex angle of the cutting edge of the disc-shaped cutter 5 is 12 degrees or less, as shown in FIG. 11, the cutting edge will be extremely sharp and will be damaged by contact with the drying plate A side. It easily wears out, shortening its lifespan, and the blade becomes too thin, making it weak as a whole, making it impractical.
If you try to strengthen the blade part X and make it smaller,
The overall blade thickness becomes thinner and weaker, and if the blade thickness itself is increased, the cutter diameter itself increases, making it difficult to handle due to the device configuration. In addition, if the apex angle is 18° or more, as shown in Figure 12, there is a disadvantage that the blade thickness becomes too large when trying to obtain the blade Y necessary for cutting raw incense sticks. Due to this widening of the apex angle, the workpiece obtained by cutting has the disadvantage that a bending deformation e similar to that obtained by push-cutting with the conventional manual cutter occurs. Regarding the blade thickness, it is desirable that the blade be relatively thin, preferably 0.8 mm or less. Also, this cutter diameter is
It is appropriate to use a relatively small blade of 30 mm to 70 mm with little distortion for the blade itself.

As described above, according to the present invention, it is possible to quickly and automatically process a large number of raw incense sticks by directly applying the drying board that has been inlaid using the conventional method, and to improve the product incense sticks obtained. Since the body cutting process involves substantial cutting, almost no deformation occurs at the cut end. This prevents breakage and the like during the convergence processing in the final process of product production. In addition, since the process of cutting the body is quick and stable, there is no bending caused by uneven drying of raw incense sticks during other processes, such as those before and after planting, and the rotational force of the disc-shaped cutter is reduced. Since it depends on the operation of the conveyor, effects such as a simplified device configuration can be obtained.
