Abstract

PURPOSE:To shorten the length of a dividing process part as a production line by restraining an interval between single piece groups from becoming larger than required in the case of dividing single pieces into the single piece groups of a large number of the single pieces. CONSTITUTION:Single pieces P1, P1 supplied to a movable belt 29 are detected by a sensor 51. The single pieces P1, P1 come to be in the state where they are accumulated on the downstream side on the upper surface of the movable belt 29 until a counter 52 reaches a set value. When the counter reaches the set value, the single pieces P1, P1 come to be in a rotating speed state equivalent to a high speed range of the movable belt 29, and high speed rotating time of a motor M continues for a certain period of time. The single pieces P1, P1 in the state accumulated on the downstream side are transferred to the downstream side integrallt at high speed. Thereafter, electric power supplied from a control means 53 is returned to a stationary state, and travel speed is returned to a low speed range. Continuously, the single piece P1 is supplied, but an interval equivalent to the high speed range is made between the following single piece P1 and the previously supplied single piece P1 on the downstream side, and they are divided into single piece groups P, P.

2. Description of the Related Art As a device for dividing a single piece such as a biscuit continuously supplied by a transfer device such as a belt conveyor into a certain number of groups, there is, for example, one shown in FIG. In this sorting device, as shown in the same figure, a transfer surface (20) inclined upward toward the downstream side is provided following the downstream end of the upstream transfer path (1), and below this, the transfer surface (20) is parallel to each other. A pair of chains that run parallel to the transfer surface (C)
(C) is provided, and the fixing pins (41) (41) are arranged on the brackets attached to the chain (C) (C) at regular intervals, and the fixing pins (41) (41) are attached to the transfer surface ( It is projected upward from 20).

A plurality of lifting pins (40) (40) are arranged between the fixing pins (41) (41) as shown in FIG. 11 and FIG. Is mounted on the bracket attached to the chain (C) (C) so that it can be moved up and down and the spring (4
It is urged downward by 3), and its attachment position is set so that the upper end thereof is lower than the transfer surface (20) at the lowered position. Above chain (C) (C)
Is to travel in a loop from the upstream end to the downstream end of the transfer surface (20), the upper traveling area is parallel to the transfer surface (20), the lower end of the lifting pins (40) (40). As shown in the figure, the chains (C) and (C) face a guide plate (K) provided in parallel with the chains in a certain range from the vicinity of the starting point of the upper traveling area. This guide plate (K) is arranged close to the chain (C) (C), and both ends are bent or inclined so as to gradually separate from the movement path of the chain (C) (C). . Therefore, the elevating pins (40) (40) facing the guide plate (K) are pushed up by the lower end of the elevating pins (40) (40) in the section close to the chains (C) (C) to transfer surface.
It will be projected from (20).

As shown in FIG. 10, the starting point of the upper traveling area of the chain (C) (C) of this sorting apparatus is, as shown in FIG.
It is arranged so as to be located near the lower front of the downstream end of (1). Therefore, if the transfer speed of the upstream transfer path (1) and the moving speed of the chains (C) and (C) are set to a predetermined timing, the upstream transfer path (1) continuously transfers them at regular intervals. Each time the single piece (P ₁ ) (P ₁ ) is moved to the transfer surface (20), it is between the fixed pin (41) and the lifting pin (40) or the lifting pin (40) (40). Between the upper and lower parts of the transfer surface (20), that is, the part where the guide plate (K) is placed,
(40) When the (40) is located, one single piece (P ₁ ) is accommodated between each pin.

In this state, the chain (C) (C) moves to the downstream side.
When moved, the lower ends of the lifting pins (40) (40) will be guided by the guide plate (K)
And the spring (43) urges it downwards below the transfer surface (20).
A single piece that was immersed and supported by this lifting pin (40)
(P₁) Slides from the downstream side to the upstream fixed pin (41) side
In this way, the single piece (P₁) (P
₁) Are stacked in the transfer direction, and the fixed
(41) and the single piece (P) at the downstream end of the single piece group (P).₁) And constant
There is an interval. That is, on the upper surface of the transfer surface (20), a single piece group
(P) (P) will be continuous at regular intervals,
Supplied in a single piece (P ₁) (P₁) Is divided into a single piece group (P) (P)
The Rukoto.

However, in the case of using the above-mentioned conventional method, the division process section becomes long and the upstream transfer path (1)
There is a problem in that a sufficient height difference must be provided between the downstream process section and the downstream process section that is continuous on the downstream side of the division process section. This is a lifting pin (40) (40) interposed between a single piece (P ₁ ) (P ₁ )
The sum of the diameters of is the minimum distance between the single piece groups (P) (P), but if the number of single pieces (P ₁ ) that make up the single piece group (P) is large, This is because the distance between the groups (P) (P) becomes unnecessarily large. Further, since the single piece (P ₁ ) is divided by moving it to the upstream side by its own weight, the transfer surface (20) needs to have a certain inclination angle, and the upstream side and the downstream side of the transfer surface (20) are required. The height difference is required in the transfer path and the process section of the part continuing to the side.

The present invention is directed to such an "upstream transfer path
(1) The method of dividing the single pieces (P ₁ ) (P ₁ ) of articles continuously supplied from (1) into a single piece group (P) in which a plurality of single pieces are overlapped ''. Even when dividing into a single piece group (P) with a large number of (P ₁ ), by ensuring that the intervals between the single piece groups (P) (P) do not become unnecessarily large, the division process part as a production line It is an object of the present invention to reduce the length of the pipe and to eliminate the need for providing a height difference between the upstream side and the downstream side of the sorting process.

<< Invention of Claim 1 >>

[0009]

[Technical Means] The technical means of the present invention taken in order to solve the above technical problem is that a "separating process section (2) having a transfer surface (20) is provided at the downstream end of the upstream transfer path (1). Continuously, at the upstream end of this division process section, the single piece (P ₁ ) supplied from the upstream transfer path (1) is stocked in the state in which the single piece (P ₁ ) is sequentially stacked on the transfer surface in the downstream direction. The single piece group (P) in the stock state is integrally transferred to the downstream side by the transfer means (3) that travels in parallel with and at a constant velocity distribution, and this transfer means (3)
The velocity distribution in the transfer by means of (1) is temporarily increased every time the number of single pieces stocked at the upstream end of the transfer surface (20) reaches a certain number.

[0010]

The above technical means of the present invention operates as follows. Single piece (P ₁ ) continuously supplied from the upstream transfer path ( ₁ )
(P ₁ ) are stocked in the upstream end portion of the transfer surface (20) provided in the sorting process section (2) in a state of being sequentially stacked in the downstream direction.

In the division process section (2), the single piece (P ₁ ) (P
_While being placed on the transfer surface (20), the transfer means (3) causes the transfer means (1) to move downstream with a constant velocity distribution. The velocity distribution of this transfer means (3) shows that the single piece (P) that constitutes the single piece group (P) is
The speed is set to a predetermined value in relation to the number of ₁ ), and the speed becomes temporarily high every time the number of pieces (P ₁ ) stocked at the upstream end of the transfer surface (20) reaches the set number.

Therefore, when the number of pieces (P ₁ ) (P ₁ ) stocked at the upstream end of the transfer surface (20) reaches the number of constituents of the piece group (P), the piece (P ₁₎ ) (P ₁ ) moves as a group at a high speed and is transferred from the upstream transfer path (1) to the transfer surface (20) and the subsequent single piece (P ₁ ) and single piece group (P) There is a certain gap between the end of the and. Then, at the time when the subsequent piece (P ₁ ) moves to the transfer surface (20), the moving speed of the transfer means (3) becomes a low speed state, and the transfer surface (20) moves from the upstream transfer path (1). The pieces (P ₁ ) and (P ₁ ) transferred to the upstream end of () are serially connected in a state of being sequentially overlapped in the downstream direction.

After that, when the above series of operations are repeated,
Single piece groups (P) (P) are arranged on the transfer surface (20) at regular intervals, and in this state, they are transferred to the downstream side along the transfer surface (20). That is, the individual piece groups (P) are moved to the downstream side in a state where they are spaced from each other and are intermittently high in speed.

[0014]

[Effects] The present invention having the above-described structure has the following unique effects. Between the single piece groups (P) (P), there is only a certain gap corresponding to the high-speed moving range of the transfer means (3).
Even when dividing into a single piece group (P) with a large number of single pieces (P ₁ ) (P ₁ ), the interval between the single piece groups (P) (P) does not become larger than necessary, so the division process part The length of (2) can be shortened.

Further, since the gap is formed between the single piece groups (P) and (P) by the speed conversion of the transfer means (3), they are divided into the upstream side and the downstream side of the partitioning process section (2). There is no need to provide a height difference, and a large margin can be made for the design of a packaging line for single pieces (P ₁ ) (P ₁ ) including the sorting process. Further, since a large number of transfer pins as in the conventional case are not provided, the transfer speed in the sorting step, that is, the sorting speed can be increased, and the transfer surface can be easily cleaned.

<< Invention of Claim 2 >>

[0017]

The invention according to claim 2 relates to an apparatus for carrying out the invention according to claim 1, in which "a single piece (P ₁ ) (at the end of the upstream transfer path (1) is (P ₁ ) is transferred to the downstream side, the transfer surface (20) is continuous, and this transfer surface is a movable surface that travels at a constant speed distribution, and the speed distribution is defined as a temporary high speed range (H) and Low speed range (L)
And the moving speed of the transfer surface (20) in the low speed region (L), the single piece (P ₁ ) supplied from the upstream transfer path ( ₁ )
(P ₁ ) is set to a constant speed which should be serially overlapped on the downstream side. '

[0018]

[Operation] The single pieces (P ₁ ) (P ₁ ) continuously supplied at a predetermined interval from the upstream transfer path (1) are sequentially transferred to the upstream end of the transfer surface (20). The surface (20) is designed to move in the downstream direction with a predetermined velocity distribution, and in the low velocity region, the intermittent transfer velocity of the single piece (P ₁ ) from the upstream transfer path (1) is reached. It has a corresponding movement speed. That is, one piece
Between the transfer of (P ₁ ) to the transfer surface (20) and the transfer of the succeeding piece (P ₁ ) to the transfer surface (20), the transfer surface (20) is a single piece (P ₁ ). Travel to the downstream side by a distance corresponding to the width in the moving direction of ₁ ). Therefore, in this low velocity region, the _single pieces (P ₁ ) (P ₁ ) are sequentially stocked in the upstream end portion of the transfer surface (20) in a serial state in which they are sequentially overlapped on the downstream side. Since the transfer surface (20) enters the high speed range (H) when this stock number reaches the set value, the subsequent single piece transferred from the upstream transfer path (1) at this point.
There is a constant interval with (P ₁ ). That is, the single piece group (P)
Will be divided into. After that, the transfer surface (20) is in the low speed state again, so that the single piece (P ₁ ) transferred to its upstream end
(P ₁ ) will be stocked in the state that they are successively stacked on the downstream side.

After that, the above series of operations proceed, and the transfer surface
In (20), a single piece group (P) consisting of a fixed number of single pieces (P ₁ ) (P ₁ ) continues at a constant interval, and is transferred downstream in this state. In this way, the method of the invention of claim 1 is carried out.

[0020]

[Effects] The present invention having the above-described structure has the following unique effects. According to the above configuration, the invention of claim 1 is smoothly implemented, and has the same effect as the invention of claim 1.
In addition, by continuously moving the transfer surface (20) with a predetermined velocity distribution, the continuously supplied single pieces (P ₁ ) (P ₁ ) are single piece groups.
(P) Since it is divided into (P), the structure for carrying out the invention of claim 1 becomes simple.

Furthermore, since the number of sections can be changed only by changing the velocity distribution of the transfer surface (20), compared with the conventional one,
It is highly versatile.

[0022]

Embodiments of the present invention will be described below with reference to FIGS. * About the first embodiment The first embodiment shown in FIGS. 1 to 3 is an apparatus for carrying out the invention of claim 1 and corresponds to the embodiment of the invention of claim 2.

In this embodiment, a belt conveyor (19) is used as the upstream transfer path (1), and the belt conveyor (19) is used.
The traveling speed of (19) is set to a constant speed, and the single piece (P ₁ ) (P ₁ )
Are transferred to the sorting process section (2) side at regular intervals. or,
The sorting process section (2) also has a structure including a transfer surface (20) composed of a movable belt (29) similar to the belt conveyor (19), and the movable belt (29) is the same as the invention of claim 1. In the relationship of, it corresponds to the transportation means (3). The upper surface of the movable belt (29) is arranged at a position lower than the upper surface of the belt conveyor (19), and shoots the downstream end of the belt conveyor (19) and the upstream end of the movable belt (29) (18). ) Let me know. Therefore, the belt conveyor (1
The single piece (P ₁ ) (P ₁ ) supplied from the downstream end of 9) is the shoot
It will be intermittently transferred to the upper surface of the belt conveyor (19) via (18).

At the upstream end of this movable belt (29), a _single piece (P ₁ ) (P
_In order to ensure that ( ₁ ) is continuously stocked, in this embodiment, the movable belt (29) travels at a speed distribution as shown in FIG. 2, and the low speed range (L) The speed of the belt conveyor (19) is synchronized with that of the traveling speed of the belt conveyor (19). That is, the belt conveyor (1
After supplying _one piece (P ₁ ) from (9), the next piece (P ₁ )
_The movable belt (29) is set to travel downstream by a distance corresponding to the width (W) of the single piece (P ₁ ) before the supply of ₁ ).

As a result, in this low speed range (L), the single piece (P ₁ ) (P ₁ ) intermittently supplied from the belt conveyor (19) to the movable belt (29) is as shown in FIG. The upper surface of the movable belt (29) is connected in series (stock) on the downstream side. Next, in order to make the traveling speed of the movable belt (29) variable, in this embodiment, the motor (M) is adopted as the drive source of the drive pulley (28), and the servo motor (M)
By temporarily increasing the rotation speed of the above, the high speed range (H) shown in FIG. 3 is realized.

The high speed range (H) is maintained at a predetermined timing for a certain period of time. Therefore, in this embodiment, the sensor arranged facing the chute (18).
(51) and a counter that counts the number of times it is output (52)
Also, the motor (M) is controlled by the control means (53) for controlling the input voltage or the input current value to the motor (M) by the output of this counter.

The sensor (51) includes a chute (18) as a single piece (P
_It outputs a constant signal when ₁ ) passes.
The counter (52) counts the number of outputs and outputs a constant output signal every time the number of outputs reaches a set value, and when the number of outputs from the sensor (51) reaches the set value. The count value is reset. The control means (53) normally supplies electric power of a constant level current value or voltage value to the motor (M), and if there is a signal input from the counter (52), it corresponds to the high speed range (H). It operates so as to supply electric power of current value or voltage value. That is, in the case of the method of controlling the rotation speed by voltage control, the high voltage is input to the motor (M) for a certain period of time, and in the case of the current control type, a large current is supplied to the motor (M) for a certain period of time. It will be. In this embodiment, the counter (5
When the count value of 2) becomes "4", it changes from the low speed range (L) to the high speed range (H).

In the embodiment having the above structure, the belt belt is intermittently moved.
Unit (P) supplied from the conveyor (19) to the movable belt (29)₁) (P
₁) Is detected separately by the sensor (51), and the number of times
Are counted by the counter (52). At the same time,
The traveling speed of the movable belt (29) is always the belt conveyor (19).
Because the speed is set to a certain value due to
Until (52) reaches the set value, as shown in Fig. 1, the movable bell
On the top of the ₁) (P₁) Overlaps with the downstream side
Become.

Then, when the counter (52) reaches the set value,
The electric power supplied from the control means (53) to the motor (M) becomes a rotation speed state corresponding to the high speed range (H) of the movable belt (29), and the timer provided in the control means (53). The high-speed rotation time of the motor (M) is maintained for a certain time by control means such as. Then, until then, the single piece that is in the state of being overlapped on the downstream side on the upper surface of the movable belt (29) (stock state)
(P ₁ ) and (P ₁ ) will be integrally and temporarily transferred to the downstream side at a high speed. After that, since the electric power supplied from the control means (53) returns to the steady state, the rotation speed of the motor (M) returns to the low speed state and the moving speed of the movable belt (29) falls in the low speed range.
Return to (L). In this state, the single piece (P ₁ ) is continuously supplied to the movable belt (29), but at this time, the subsequent single piece (P ₁ ) and the downstream single piece that was previously supplied. A space corresponding to the high speed region (H) is generated between the piece (P ₁ ). That is, a single piece (P
₁ ) (P ₁ ) will be divided into single-piece groups (P) (P) as shown in FIG.

In the above, the specific relationship among the sensor (51), the counter (52) and the control means (53) is shown in FIG.
The configuration shown in can be adopted. The control device shown in the figure temporarily raises the speed of the motor (M) by voltage control, and a counter (52) to which the output of the sensor (51) is input.
A combination of a switching transistor (54) that is turned on by the output of and a relay (R) connected in series to this is adopted, and the output contact of this relay (R) becomes the switching contact (56). There is. Therefore, when the relay becomes conductive, the switching contact (56) is connected to the high voltage circuit (55), and the motor connected in series to the switching contact (56).
When a high voltage is supplied to (M) and it is in a high speed drive state, and conversely the relay (R) is in the non-conducting state, the switching contact is connected to the low voltage circuit (57) side, and the motor (M) Becomes a low speed drive state. As a result, the above-mentioned velocity distribution of the movable belt (29) can be obtained.

In the above embodiment, the moving speed of the movable belt (29) is switched from the low speed range (L) to the high speed range (H) by the outputs of the sensor (51) and the counter (52). However, the moving speed of the belt conveyor (19) and the movable belt
If the moving speed in the low speed range (L) of (29) can be accurately maintained at a constant speed, the start timing and end time of the high speed range (H) may be controlled only by time. This is because the time required to count the single pieces (P ₁ ) (P ₁ ) forming the single piece group (P) matches the time required for the low speed range (L).

* Regarding the Second Embodiment Next, the second embodiment shown in FIGS. 4 to 9 uses the first transfer path (X) arranged in the transfer direction as the upstream transfer path (1). A belt (10) with a large number of transfer rods (11) (11) protruding upward
The transfer device is configured to run in parallel with the transfer path. Then, from the combination of the stock device (S) at the downstream end of the upstream transfer path (1), the loop-shaped traveling body (31) equipped with the transfer claws (30) and (30), and the transfer surface (20). It consists of a continuous division process section (2).

Stock device of the dividing process section (2)
(S) consists of a pair of cams (9) (9) whose outer shape is a windmill,
At the upstream end of the transfer surface (20), change the posture of the biscuit as a single piece (P ₁ ) that is transferred at regular intervals by the transfer rods (11) (11) of the belt (10) from the sideways state to the upright state. They are stocked in series. Because of this, the cam
(9) Six notches (90) (90) are formed around (9),
Each notch (90) (90) is an arcuate portion (91) that is inclined obliquely, a straight line portion (92) in the radial direction following this, and a protrusion formed at the tip of this straight line portion (92) ( 93) and the straight part (92)
Is slightly larger than the thickness of the biscuit, and the arcuate portion (91) is set rearward in the rotational direction to approach the peripheral edge of the cam (9). Also, this cam (9)
The rotation speed of (9) is synchronized with the moving speed of the belt (10), and when the biscuits in the lying state are transferred to the downstream end of the belt (10), the notches (90) and (90) cause the belt (10) to move. It is designed to coincide with the downstream end of 10).

Further, the transfer surface (20) has a pair of guide bars (22) (2) having an L-shaped cross section which protrudes to the outside of the ends of the cams (9) (9).
2), the space between the upright walls of the guide bars (22), (22) is set slightly larger than the width of the biscuit as a single piece (P ₁ ), and its height is the same as the height of the biscuit. It is set lower than Sa. In addition, the transfer surface (2
The bottom surface of (0) is arranged at a position lower than the first transfer path (X) by one step.

Then, the outward path of the first chain (32) constituting the loop-shaped traveling body (31) runs parallel to the outside of each guide rail (22), and a plurality of transfer claws (30) ( The part (30) projects inwardly beyond the upright wall of the guide bar (22). The first chains 32 and 32 are driven and driven by one driving means so that they travel in synchronization with each other. In this embodiment, a variable speed motor (not shown) such as a motor is used. is doing.

At the upstream side of the sorting process section (2) having the above construction, the biscuits intermittently transferred by the transfer rods (11) (11) of the belt (10) are located downstream of the first transfer path (X). Cam at the edge
(9) It is fed into the notches (90) and (90) of (9), and when it rotates, the biscuit comes into contact with the bottom of the transfer surface (20) when the biscuit approaches the upright posture, and the cam ( 9) When (9) rotates, it is pushed into the downstream side of the transfer surface (20) in the abutting state by a distance corresponding to the inclination degree of the arc of the arc-shaped portions (91) (91). This push-in distance is from the end of the straight part (92)
It corresponds to the distance to the periphery of (9), and this distance approximately corresponds to the thickness of one piece of biscuit. The biscuit pieces are now transferred to the transfer surface (20) in an upright position.

At the time when the transfer to the transfer surface (20) for one biscuit piece is completed, the subsequent notch (90) and the transfer rod (1
The biscuits transferred by 1) coincide with each other at the downstream end of the first transfer path (X), and the biscuits are transferred to the transfer surface (20) in the upright state by the same procedure as above. In this way, the biscuits moving on the first transfer path (X) are sequentially stocked in the upright state and in the overlapping state.

Next, the loop-shaped traveling body (31) for dividing the stocked biscuits into a fixed number of biscuits will be described. The forward side of the pair of loop-shaped traveling bodies (31) (31) arranged outside the guide bars (22) (22) is set parallel to the guide bars (22). The loop-shaped traveling body (31) comprises a first chain (32) and a plurality of transfer claws (30) (30) attached to the chain link of the first chain (32) to form the first chain (32). A part of the chain link is provided with a claw body projecting inside the guide bar (22), and this serves as the transfer claws (30) (30). The distance between the transfer claws (30) and (30) should be slightly larger than the length of the single piece group (P) in the transfer direction (the overlapping length of the single side (P ₁ ) (P ₁ )). Is set to. In addition, loop-shaped running body (31)
The traveling height of (31) depends on the relationship with the guide rail (22) and the guide rail.
(22) It is set to a predetermined value in relation to the biscuit that moves between (22), and when the transfer claws (30) (30) project above the guide bars (22), the upper rear surface of both ends of the biscuit Will be faced with.

Each of the loop-shaped running bodies (31) (31) having the above-mentioned structure is wound between the sprockets (33) (33), and these sprockets (33) (33) serve as the transfer surface (20). Become a guide cross
(22) Located outside the vicinity of the upstream and downstream ends of (22). Then, at the upstream side (33) of the transfer surface (20), the first chain (32)
The transfer claws (30) (30) attached to the chain link of (1) enter the guide bar (22) from the lateral outside of the guide bar (22), and this insertion position is the position of the cam (9) (9). It is the end on the transfer surface (20) side.

Since the transfer claws (30) (30) which operate in this way are arranged on both sides of the transfer surface (20), the transfer device (S) is used by the stock device (S) as shown in FIG. The biscuits stocked at the upstream end of the are in the downstream side when the transfer claws (30) (30) enter the upper area of the transfer surface (20) according to the operation of the loop-shaped traveling body (31) (31). And the transfer speed matches the moving speed distribution of the loop-shaped traveling bodies (31), (31).

In particular, in this embodiment, the loop-shaped traveling body (3
1) and (31) are set so that they travel in synchronization with each other, and their traveling speed distributions are the same as those in the first embodiment shown in FIG.
, The high speed region (H) and the low speed region (L), and the number of biscuits stocked by the stocking device (S) is fixed (5 in this example). ), The high speed range (H) is entered. Therefore, as described above, every time the number of biscuits stocked by the stock device (S) reaches the set quantity, the transfer claws (30) (30) attached to the first chain (32) (32) are cammed.
(9) From the outside of (9), it enters the upper area of the transfer surface (20) at a speed that matches the high speed area (H), and the biscuit group that had been stocked up to that point is downstream of the transfer surface (20). Transferred to the side temporarily at high speed. At this time, the cams (9) (9) are on the first transfer path.
Transfer the biscuit sent from (X) at a constant speed.
Although it is stocked at the upstream end of (20), the transfer claws (30) (30)
By this operation, a certain interval is generated between the trailing biscuit and the subsequent biscuit that are temporarily transferred to the downstream side at a high speed.

Thereafter, this operation is continued, and the biscuit stocked on the upper surface of the transfer surface (20) is divided into a predetermined number by the stocking device (S) so that the loop-shaped traveling body (31) (31) ) Is transferred to the downstream side. It is needless to say that the method of the first embodiment can be directly adopted as the control method of the motor for driving the loop-shaped traveling body in this embodiment as well.

Further, the number of the loop-shaped traveling bodies (31) may be one. Further, in this case, the loop-shaped traveling body (31) is attached to the transfer surface.
The transfer claws (30) and (30) may be arranged above or below the (20) so that the transfer claws (30) and (30) project into the transfer area above the transfer surface (20) in the forward path. Further, in this embodiment, a transfer device as shown in FIG. 6 is continuously provided in the downstream transfer path (6), and the biscuit group divided in the above-mentioned separation process section (2) is further downstream. Be transferred.

For this reason, the downstream transfer path (6) has the second chain (61) running in a loop and the arm (6
2) and swinging arm (63), and this arm (62) and swinging arm (63)
The interval of is matched with the length of the biscuit group,
These arms (62) and swing arms (63) project at the downstream end of the transfer surface (20). In order to realize this operation, the second chain (61) is set so as to move upward at the downstream end of the transfer surface (20) and then move horizontally, and the arm (62) is moved as shown in FIG. , Is directly fixed to the chain link of the second chain (61) and projects in a direction perpendicular to this.
