The top knife 7 is slidably supported on the upper surface of the main ram 8 and is supported by the top knife drive transmission mechanism T so as to reciprocate in the dough chamber 3 so as to move slightly ahead of the movement of the main ram 8. There is.

Further, the divided head 5 is disposed by a divided head drive transmission mechanism S so as to be slidably in contact with the front end surface of the dough chamber 3 and movable in the vertical direction. And the split head 5
Is divided into a plurality of divided chambers 6, and each of these divided chambers 6 has
It is adapted to communicate with the dough chamber 3 through the opening 3a. An auxiliary ram 9 is slidably fitted in each of the division chambers 6. Next, the drive transmission mechanism of the bread dough dividing device mainly includes a top knife drive transmission mechanism T, a divided head drive transmission mechanism S, a main ram drive transmission mechanism R, and the like.

First, the top knife drive transmission mechanism T mainly comprises a top knife cam 12, a first drive lever 14, a pair of top knife connecting arms 15a and 15b, and the like. The top knife cam 12 includes two side frames 10a,
Both side frames 10a are attached to the cam shaft 11 pivotally supported by 10b,
It is fixed inside 10b. First drive lever 14
Is provided at an end of a boss 21 that is rotatably supported by a first lever shaft 13 fixed between the both side frames 10a and 10b. A pair of connecting arms for top knives
5a and 15b are connected to the boss 21 and the rear end of the top knife 7, respectively, and are arranged inside the side frames 10a and 10b, respectively.

Next, the split head drive transmission mechanism S is mainly composed of a split head cam 19, a second drive lever 20, and the like. The split head cam 19 has a common cam shaft 11
It is fixed inside the both side frames 10a, 10b. The second drive lever 20 is connected to the split head cam 19 and the split head 5, and is provided on both side frames 10a and 10b.

It is swingably supported inside b.

Next, the main ram drive transmission mechanism R is mainly composed of a main ram cam 17, a third drive lever 18, a main ram connecting arm 23 and the like. The main ram cam 17 is fixed to the common cam shaft 11 inside both side frames 10a and 10b. The third drive lever 18 is swingably supported at substantially the center of the first lever shaft 13. The main ram connecting arm 23 is connected to the third drive lever 18 and the rear end of the main ram 8 via a compression spring 24.

Next, the operation of the above-mentioned bread dough dividing device will be described in detail below with reference to the process diagrams of FIGS. In the initial state, the split head 5 is located at the descending end, the communication port 4 between the hopper 2 and the dough chamber 3 is blocked by the top knife 7 located at the advancing end, and the main ram 8 is also located at the advancing end. positioned.

(1) Suction Step First, as shown in FIG. 4, the main ram 8 is started to move backward by the operation of the main ram drive transmission mechanism R described above. Next, the top knife 7 is moved backward by the operation of the top knife drive transmission mechanism T later than the backward movement of the main ram 8, and then the communication port 4 between the lower end of the hopper and the dough chamber 3 is opened. At this time, the split head 5 is located at the lower end by the operation of the split head drive transmission mechanism S.

Therefore, the front opening 3a of the dough chamber 3 is closed by the wall of the divided head 5. Therefore, the inside of the dough chamber 3 is in a negative pressure state due to the backward movement of the main ram 8 slightly ahead of the top knife 7. Then, when the top knife 7 is moved backward, the bread dough M in the hopper 2 is sucked by the negative pressure and the dough chamber 3 is sucked by its own weight.
It is moved in and filled.

(2) Compressing Process The top knife 7 shown in FIG. 5 first moves forward by the operation of the top knife drive transmission mechanism T, and shields the communication port 4 between the lower end of the hopper 2 and the dough chamber 3. Next, the main ram 8 moves forward in the closed dough chamber 3 filled with the bread dough M1 slightly behind the top knife 7 due to the operation of the main ram drive transmission mechanism R. At this time, since the divided head 5 is located at the rising end by the operation of the divided head drive transmission mechanism S, the plurality of divided chambers 6 communicate with the dough chamber 3 through the openings 3a. Therefore, the bread dough M1 in the dough chamber 3 is pressed by the forward movement of the main ram 8 and is filled in the divided chambers 6 that are divided.

At the time of this filling, the auxiliary ram 9 which is slidably fitted in each of the division chambers 6 is pushed outward along with the filling of the bread dough M1. By this pressing movement, the auxiliary ram 9 comes into contact with the stopper 25 provided on the extension line of the moving direction of the auxiliary ram 9. The stopper 25 has a configuration in which the contact position with the auxiliary ram 9 can be adjusted, so that the movement amount of the auxiliary ram 9 can be appropriately set.

Therefore, the volume of the dough to be filled in the dividing chamber 6 is determined by the contact position of the auxiliary ram 9 with the stopper 25. Needless to say, the stroke of the main ram 8 can be adjusted according to the adjusted position of the stopper 25. As one of the adjusting means, for example, a spring may be used to absorb the change in stroke.

(3) Dividing Process When the filling of the dough into the dividing chambers 6 is completed as shown in FIG. 6, the main ram 8 and the top knife 7 move backward, and while the respective moving to the rearmost position. The divided head 5 is moved downward by the divided head drive transmission mechanism S. During the downward movement, the dividing head 5 cuts the dough filled in the dividing chamber 6 and the dough chamber 3 into M1 and M2. In this way, the division head 5 can simultaneously produce a plurality of predetermined amounts of divided dough.

(4) Discharging Process When the dividing head 5 shown in FIG. 7 reaches the lower end, the pushing rod 26 arranged corresponding to the auxiliary ram 9 in each dividing chamber 6 is moved forward, whereby the auxiliary ram 9 is moved. Are pushed into the division chamber 6. As a result, the dough M2 in each division chamber 6
Is entirely extruded from the opening side through the auxiliary ram.

Next, the division head 5 starts to move upward, but during this time, the division material M pushed out from each division chamber 6
2 is scraped off onto the discharge conveyor 28 by the counterclockwise swing of the flicker plate 27 arranged on the opening side of each division chamber 6. In this way, each step is sequentially repeated, and when this cycle is completed, the main ram 8, the top knife 7, and the split head 5 return to the initial state.

The operation of the bread dough dividing device has been described above. As can be understood by the operation thereof, a part of the bread dough leaks to the outside while the dough dividing device repeats the cycle of dividing the dough. was there. That is, such leakage occurs from the divided head side and the opposite side through the minute gap formed on the abutting surface between the main ram 8 and the dough chamber 3 or the top knife 7. Thus, the drive transmission mechanisms R, T, S are housed between the frames 10a, 10b, and the leaked bread dough drops on the upper portions of the drive transmission mechanisms R, T, S. Adhere to.

Therefore, as a countermeasure, each drive transmission mechanism R,
In the present situation, the saucer 29 is horizontally arranged above the T and S to catch the leaked bread dough. However, the saucer 29
Will soon become full because its size is limited due to the constraints of the storage space between both frames 10a, 10b.

Moreover, since it is installed in a horizontal state due to space restrictions, it cannot be discharged to the outside, and its tray 29
The dough contained in the store will eventually overflow and fall. Then, the overflowing dough is the side frame 10 shown in FIGS.
The main ram 8 between a and 10b, the top knife 7, the drive transmission mechanisms R, T, S of the split head 5, and other machine parts are attached and accumulated.

The dough thus deposited and deposited is
This causes a hindrance to the operation of the bread dough dividing device and shortens the life of the device. Also, if left unattended, it will be unfavorable for hygiene. On the other hand, each drive transmission mechanism R, T, S
Are disposed in the limited space between the both side frames 10a and 10b, respectively, so that it is a difficult task when performing maintenance of the mechanical device.

In addition, it is extremely troublesome to remove the bread dough adhering to the parts arranged in the narrow space between the both side frames 10a and 10b or accumulating on the bottom. In this way, the efficiency of maintenance and cleaning is poor, so that the operation rate is lowered and the productivity is not improved.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described below with reference to the drawings with reference to the embodiments. FIG. 1 is a side view of a bread dough dividing device showing an embodiment of the present invention, and FIG. 2 is a rear view of the bread dough dividing device.

As shown in the figure, the bread dough dividing device mainly shields the hopper 31, the dough chamber 32, the main ram 33, the top knife 34, the dividing head 35, and the communication port 36 between the hopper 31 and the dough chamber 32. A top knife drive transmission mechanism T, a main ram drive transmission mechanism R for pressing and filling the bread dough in the dough chamber 32 into the dividing chamber 37, and the dividing head 35 is moved downward to the dividing chamber 37 and the dough chamber 32. It is composed of a split head drive transmission mechanism S and the like for separating the bread dough that is filled across.

More specifically, the hopper 31 is composed of an upper hopper 31a and a lower hopper 31b,
The lower hopper 31b is connected to the dough chamber 32 through the communication port 36.
It is open to the public. The inner peripheral surface of the hopper 31 is preferably a smooth surface and non-adhesive to the cloth, and is preferably formed by a special coating or a resin material. The dough chamber 32 is formed in the base Ua shown in FIG. 1, and the base Ua is inclined downward (15 degrees with respect to the horizontal plane) toward the front between the pair of frames 38 a and 38 b arranged side by side on the base 30. It is fixed at (° -30 °).

This downward slope is adopted to improve the fluidity of the dough in the hopper 31 and the dough chamber 32, and is extremely effective. The dough chamber 32 is arranged at the lower end of the hopper 31 supported on the upper part of the base Ua, and is configured to open to the hopper through the communication port 36. Then, the top knife 34 and the main ram 33 are fitted in the dough chamber 32 in a state of vertically slidingly contacting each other. The main ram 33 is supported in the dough chamber 32 by the main ram drive transmission mechanism R in a reciprocally movable state.

The top knife 34 is slidably supported on the upper surface of the main ram 33 and is reciprocally movable by the top knife drive transmission mechanism T. Top knife 34
Are supported in the dough chamber 32 so as to move slightly ahead of the forward movement of the main ram 33. Here, referring to the movement of the dough, since the rear wall surface of the hopper 31 is inclined toward the front communication port 36, the cloth M near the communication port 36 or the rear wall surface of the hopper is the top knife 34.
Is moved forward, it is pulled by the tip of the top knife 34 and moved forward.

At the time of this movement, since the rear wall surface of the hopper 31 is inclined, the cloth in the vicinity thereof is smoothly drawn into the cloth chamber 32 along the slope. On the other hand, the split head 35 is arranged so as to be slidably in contact with the front end face of the dough chamber by a split head drive transmission mechanism S (not shown) and movable in the vertical direction. Further, the division head 35 is formed into a plurality of division chambers 37 whose interior is partitioned and formed, and each of the division chambers 37 is formed through the opening 32a when the division head 35 is at the rising end. It is possible to communicate with 32. In addition, an auxiliary ram 38 is slidably inserted into each of the plurality of divided chambers 37 that are partitioned and formed.

On the other hand, a stopper 39 is arranged on the movement line of the auxiliary ram 38 of the plurality of division chambers 37, and the auxiliary ram 3
The contact position with 8 can be adjusted. The stopper 39 abuts when the auxiliary ram 38 moves along with the filling of the cloth, and determines the depth of the division chamber 37. As a result, the amount of dough to be pressed and filled in the division chamber 37 is regulated. A pair of push rods 40 are disposed below the split head 35 so as to be movable back and forth. The extruding rod 40 has a pair of extruding rods 40 and a connecting shaft 4 at the tip thereof.
0a is connected.

When the dividing head 35 descends, the pushing rod 40 is moved backward so that the auxiliary ram 38 is pushed into the dividing chamber 38 through the connecting shaft 40a and the dough in the dividing chamber 38 is discharged. It is a thing. Here, the pushing rod 40 is located in the retracted position (that is, the position close to the split head 35) when the auxiliary ram 38 is pushed into the split chamber 38 via the connecting shaft 40a. Next, the split head 35 is raised again to move the dough chamber 32.
The dough inside is filled in the dividing chamber 38, and at this time, the auxiliary ram 38 moves forward and projects forward from the dividing head 35.

Therefore, when the dividing head 35 descends,
The auxiliary ram 3 in which the connecting shaft 40 a projects from the split head 35 is caused by moving the push-out rod 40 located in the retracted position forward (position separated from the split head 35) and waiting.
Avoiding interference with 8.

When the dividing head 35 filled with the divided dough descends to the lower end, the auxiliary ram 38 is pushed into the dividing chamber 38 by the backward movement in the arrow direction via the connecting shaft 40a of the pushing rod 40. As a result, the plurality of divided doughs in each of the divided chambers 38 are extruded to the outside via the auxiliary ram 38, scraped off by the descending motion of the flicker plate 41, and placed on the conveyor 42 arranged below. Will be placed.

Next, the top knife drive transmission mechanism T, the main ram drive transmission mechanism R, and the split head drive transmission mechanism S for respectively driving the top knife 34, the main ram 33, and the split head 35 configured as described above are sequentially arranged. explain. First, the top knife drive transmission mechanism T is mainly composed of a drive shaft 44, a first drive disk 45, an operating rod 46, a first lever shaft 47, a first link lever 48, a top knife lever 49 and the like. The drive shaft 44 is connected to the drive source 43 and is rotatably supported by both frames 38a and 38b.

The first drive disk 45 has a drive shaft 44.
Are fixed to both ends of the frame outside the frames 38a and 38b. Further, one end of the operating rod 46 is axially supported by the eccentric pin 50 of the first drive disc 45, and the other end thereof is the top knife lever 4.
It is elastically and rotatably supported by an intermediate shaft 51 of No. 9.
It should be noted that this operating rod 46 is thereby provided with the top knife lever 4
When moving 9 forward, the other split heads and main rams return to their initial positions, and the flexure of the compression spring is used to wait at the forward end until the conditions for starting the dough dividing device are met. Is.

Specifically, as shown in FIG. 3, the operating rod 46
Is composed of a first locking portion 52, a cylinder 54, a cap 53, a compression spring 55, a second locking portion 56, a third locking portion 57 and a locking rod 58. Then, the first locking portion 52 is the first
Insertion hole 5 for axially supporting the eccentric pin 50 of the drive disk 45
9, a bracket 61 having a flange 60a. The cylindrical body 54 has a flange 60b attached to the flange 60a of the first locking portion 52 at one end, and a screw 62 for screwing the cap 53 is screwed at the other end.

A through guide hole 63 having a guide bush mounted therein is formed in the head of the cap 53. On the other hand, the second locking portion 56 has the insertion hole 6 that supports the intermediate shaft 51.
4 and a boss 66 extending from the bracket 65 and having a screw hole formed at an end thereof. The locking rod 58 has a threaded portion 67 that is screwed into the threaded hole of the boss 66 at one end, and has a third locking portion 57 at the other end.

Referring back to FIGS. 1 and 2, the top knife lever 49 mainly includes the first top knife lever 49a and the second top knife lever 49a.
It consists of a top knife lever 49b and the like. One end of the first top knife lever 49a is rotatably supported by the end of the first lever shaft 47 outside the frames 38a, 38b, and the other end thereof is supported by the intermediate shaft 51.

The second top knife lever 49b is
One end has a first link lever 48 at the rear end of the top knife 34.
Is pivotally supported via the first top knife lever 4
The intermediate shaft 51 of 9a is rotatably supported. The extended end extending from the intermediate portion is engaged with the first top knife lever 49a via the shear pin 68.

Next, the operation of the operating rod 46 will be described below. The operating rod 46 has the first drive disk 45 in the insertion holes 59 and 64 of the first locking portion 52 and the second locking portion 56 at both ends.
Eccentric pin 50, intermediate shaft 51 of top knife lever 49
Are inserted and locked. Returning now to FIG. 1, the operating rod 46 extends and contracts in the axial direction via the eccentric pin 50 which is eccentrically rotated by the first drive disk 45. That is, when the eccentric pin 50 rotates counterclockwise from the position (bottom dead center) in FIG. 1, the top knife lever 49 is also swung counterclockwise to move the top knife 34 to the forward position.

When the side surface of the first top knife lever 49a of the top knife lever 49 is brought into contact with a stopper (not shown), the movement of the top knife lever 49 is stopped, but the eccentric pin 50 of the first drive disk 45 is reversed. Continue to rotate clockwise. Therefore, although the operating rod 46 extends in the axial direction, when the eccentric pin 50 passes (top dead center) and reaches a predetermined position, the dough dividing device starts to start from the initial position and the top knife 34 moves backward. start.
This is the top knife lever 49 via the eccentric pin 50.
Is oscillated clockwise, and the operating rod 46 is compressed in the axial direction while being contracted.

Due to the expansion and contraction of the operating rod 46, the top knife lever 49 swings in the clockwise and counterclockwise directions via the intermediate shaft 51, so that a varying load of compressive force or tensile force acts. When a compressive force is applied to the operating rod 46, the state shown in FIG. 3A is obtained, and when a tensile force is applied, the state shown in FIG. 3B is obtained. That is, in the case of FIG. 3A, the end of the compression spring 55, which is internally housed in the tubular body 54, is locked to the third locking portion 57 of the locking rod 58, so that a slight preload may occur. It is in the state that it is set in the hanging state.

Therefore, the third locking portion 57 is in contact with the bottom of the cylindrical body 54, that is, the end of the bracket 61. Further, in the case of FIG. 3B, the first top knife lever 49a is in contact with a stopper (not shown) and stopped, and the eccentric pin 50 is rotated counterclockwise by the first drive disk 45. By moving, the operating rod 46 is in an extended state.

In this case, the operating rod 46 extends between the intermediate shaft 51 and the eccentric pin 50 by, for example, α at the maximum. In this case, the compression spring 55 is pressed and compressed by the third locking portion 57 of the locking rod 58 and the cap 53 at the end of the tubular body 54 that moves together with the first locking portion 52.

Next, returning to FIGS. 1 and 2, the operation of the top knife drive transmission mechanism T will be described. As shown in Figure 1,
When the first drive disk 45 rotates counterclockwise, for example, when the drive shaft 44 is activated, the top knife lever 49 rotates,
The intermediate rod 5 is locked by the operating rod 46 that is locked to the eccentric pin 50.
Swing counterclockwise via 1. By this swinging, the top knife 34 moves forward through the first link lever 48 connected to the upper end of the top knife lever 49.

The first top knife lever 49a, which constitutes the top knife lever 49, simultaneously comes into contact with a stopper (not shown) when the top knife 34 moves to the forward end.
In this case, the first drive disk 45 continues to rotate, and a tensile force acts on the operating rod 46 that is pulled through the eccentric pin 50 so as to extend between the intermediate rod 51 and the operating rod 4.
The compression spring 55 installed in 6 is compressed.

That is, the compression spring 55 makes the top knife 34 stand by at the forward position until immediately after the split head 35 has moved to the rising end and the main ram 33 has started the backward movement. As a result, the timing of the top knife 34 is adjusted by making the top end of the top knife 34 stand by at the forward end by utilizing the bending of the compression spring until the conditions for starting the material dividing device are met.

Next, the main ram drive transmission mechanism R will be described. The main ram drive transmission mechanism R mainly includes a drive shaft 44, an eccentric wheel 69, a pair of second main ram levers 71, a connecting rod 72, a compression spring 73, a first main ram lever 75, and the like. The eccentric wheel 69 is rotatably supported in the middle of the drive shaft 44 in an eccentric state. One end of each of the pair of second main ram levers 71 is fixed in the middle of the first lever shaft 47, and the support shaft 70 is rotatably supported at the other end. One end of the connecting rod 72 is attached to the end of the eccentric wheel 69,
The other end is inserted and locked to the support shaft 70 of the second main ram lever 71.

The compression spring 73 is mounted on the connecting rod 72,
Moreover, it is interposed between the eccentric wheel 69 and the second main ram lever 71 to press and urge the second main ram lever 71.
The first main ram lever 75 has one end fixed to the end of the first lever shaft 47 outside the frames 38a, 38b, and the other end pivotally supported at the rear end of the main ram 33 via the second link lever 74. .

The main ram drive transmission mechanism R configured as described above operates as follows. That is, the first main ram lever 75 rotates the drive shaft 44 to drive the eccentric wheel 6.
9 makes eccentric rotation, and is swung in the clockwise and counterclockwise directions by the compressive force acting on the support shaft 70 of the pair of second main ram levers 71 via the connecting rod 72 and the compression spring 73.

Due to this swing, the main ram 33 moves back and forth. For example, if it moves forward, the dough enclosed in the dough chamber by the top knife 34 that has already moved is divided into the divided chambers 37 of the divided heads 35 waiting forward.
It is pressed and filled inside. However, during this pressure filling,
In the dough chamber 32, there will always be residual dough that is not pushed into the division chamber 37. Therefore, in the next step, the main ram 33 is pressed and filled in the division chamber 37 together with the dough remaining in the dough chamber 32 and the dough introduced next.

Further, the stroke amount of the main ram 33 varies because the amount of the dough in the dough chamber is divided depending on the product to be manufactured (the amount stored in the divided chamber). Therefore, the compression spring 73 absorbs the stroke fluctuation of the main ram 33 by the difference in the bending amount of the compression spring 73. Further, the retreating operation of the main ram 33 is performed by the pulling operation of the connecting rod 72 which is eccentrically rotated by the eccentric wheel 69 and the clockwise swinging operation of the first and second main ram levers 75 and 71 about the first lever shaft 47. Done by

Next, the split head drive transmission mechanism S will be described. The split head drive transmission mechanism S is mainly composed of a second lever shaft 76, a drive disk 77, a split head arm 79 and the like. The second lever shaft 76 is connected to a drive source and is rotatably supported on both frames 38a and 38b on the outer side thereof. The drive disk 77 is
It is fixed to both ends of the second lever shaft 76 outside the frames 38a and 38b. Furthermore, the split head arm 79
Has one end pivotally supported by the eccentric pin 78 of the drive disk 77 and the other end pivotally supported by the side surface of the split head 35.

The divided head drive transmission mechanism S thus constructed operates as follows. When the drive disc 77 is started, the eccentric pin 78 also eccentrically rotates together with the drive disc 77, thereby moving the divided head arm 79 upward. When the split head arm 79 starts to move upward, the split head 35 starts to move upward from the lower end position shown in the figure via the split head arm 79.

When the work for filling the material into the dividing chamber 37 is completed at the rising end of the dividing head 35, the dividing head arm 79 is caused by the eccentric rotation of the eccentric pin 79 by the drive disk 77.
The downward movement is performed again via. By the downward movement of the dividing head 35, a part of the dough filled in the dividing chamber 37 is cut from the dough in the dough chamber 32, and a predetermined amount of divided dough is produced.

As described above, the top knife drive transmission mechanism T, the main ram drive transmission mechanism R, and the split head drive transmission mechanism S can be arranged outside the frames 38a, 38b. A sufficiently wide space is formed inside 38b. Therefore, in this space portion, the saucer 80 having a steep downward slope toward the back surface of the apparatus is provided.
And a discharging means 8 comprising a receiving box 81 arranged at the lower end thereof
It has become possible to set 0.

The tray 80 is formed so as to have a width that is the inside of both frames 38a and 38b from the lower surface of the top knife and the rear end position of the main ram, and is installed so as to be inclined downward toward the rear surface of the apparatus. Furthermore, the receiving box 81 installed at the lower end of the receiving tray 80 can be taken out to the outside.

As a result, the dough leaked from the rear end of the top knife and the main ram falls into the tray 80, slides down the inclined portion, and is finally housed in the receiving box 81. When a certain amount of the leaking cloth is accumulated in the receiving box 81, the door (not shown) is opened, the receiving box 81 is taken out, and the leaking cloth is discarded. Further, since the top knife drive transmission mechanism T, the main ram drive transmission mechanism R, and the split head drive transmission mechanism S are arranged outside both frames 38a, 38b, maintenance of this type of mechanism becomes easy. Although the present invention has been described above, the present invention is not limited to the embodiments, and various other modifications are possible without departing from the essence thereof.

By arranging all the various drive transmission mechanisms on the outside of both frames, a sufficient space can be obtained between both frames. Therefore, maintenance of each drive system of the bread dough dividing device can be easily performed. Furthermore, the leaked bread dough can be reliably received without leaking inside the device, and can be easily discharged to the outside.
