Description

The present invention relates to a bread cutting machine that cuts bread that has been baked into a relatively large block into an arbitrary thickness to obtain bread pieces.

  Conventionally, bread that has been baked in a block shape is cut into bread pieces having a predetermined thickness by using a bread cutting device, and the bread pieces are sold by packing a predetermined number of pieces, or further to sandwich bread. It is processed and sold. In general, a reciprocating machine is well known as the above-described bread cutting machine. This reciprocating machine has a large number of strip-shaped cutting blades arranged side by side, and can obtain a large number of bread pieces at a time from bread. Further, the bread pieces obtained in this way are arranged in a horizontal manner on the conveyor by hand, and are sent out for the next packing work.

  By the way, the strip-shaped cutting blade included in the reciprocating cutting machine has a sawtooth-shaped cutting blade, and at the time of cutting, it is reciprocated while being pressed against the bread. Therefore, it is difficult to obtain a smooth cut surface for the cut bread pieces, and there is a demand for obtaining a smoother cut surface and improving the commercial value. In addition, the baked bread has a relatively hard outer surface, while the inside is soft, and each part becomes slightly harder as time passes after baking. And since the reciprocating cutting machine mentioned above cuts bread by reciprocating movement of the cutting blade, if the bread is cut early after baking, the bread piece being cut will be deformed, so that the bread of the desired shape and size While it may not be possible to obtain a piece, in order to avoid this, if it is attempted to secure an appropriate hardness to the bread, it must be cut after a relatively long period of time (usually at least 24 hours after baking). Since it becomes impossible, the fall of the freshness of the obtained bread piece is inevitable.

  Furthermore, when using a reciprocating cutting machine, it is necessary for workers to sequentially align and replace the obtained bread pieces on the transport conveyor, so the productivity may be greatly affected by the work ability of the workers. . In addition, it is desirable that the obtained bread pieces should not be touched by humans as much as possible. However, when a reciprocating cutting machine is used, there is a possibility that an operator may come into contact with the obtained bread pieces. .

In order to cope with such circumstances, the applicant of the present application has invented a bread cutting device using a round blade (see Patent Document 1). In the case of the bread slicing device according to Patent Document 1, the round blades are movable up and down while rotating, and are configured to slice while raising the bread placed on the feeding table. In addition, a bread piece pedestal that rises together with the round blade and enters the cut end of the bread and receives the cut bread pieces is also provided. With such a configuration, the bread slicing device according to Patent Document 1 can cut bread with a round blade at an early stage after baking, obtain a bread piece with a well-organized cutting surface, and remove the bread piece. The operation of receiving and transferring the transfer conveyor for the next process can be performed without human intervention.
Patent No. 3844759 By the way, in the conventional bread cutting apparatus including the above bread cutting apparatus, periodic maintenance such as a round blade is necessary, and depending on the degree of wear, it is necessary to remove and replace it with a new one. However, in the case of the above-mentioned bread cutting device, since the round blade is disposed in the gap between the feeding table and the conveyor, the worker enters the lower part of the feeding table or the conveyor when the round blade is maintained. Or, it is troublesome because it is necessary to work by temporarily removing the conveyor.

  Furthermore, in recent years, downsizing of a bread cutting apparatus has been desired due to the limitation of installation space and the demand for cost reduction. And if the bread bread cutting device concerning patent documents 1 mentioned above is reduced in size, since the lower space of a feeding stand and a conveyance conveyor will also become narrow, it will be more difficult to go under these and perform maintenance. It becomes a thing.

  Therefore, an object of the present invention is to provide a bread slicing apparatus that can be reduced in size and price and can be improved in maintainability.

  The present invention has been made in view of the above-described circumstances, and a bread cutting apparatus according to the present invention includes a transfer table that regulates the transfer direction of the loaded bread, and the transfer table in the transfer direction of the bread. A reciprocating drive unit that reciprocates in a horizontal direction perpendicular to the crossing direction; and a reciprocating drive that is disposed downstream of the transfer table in the transfer direction of the bread and cuts the transferred bread. The part is configured to reciprocate the transfer table between a facing position facing the cutting part and an exposure position where the cutting part is exposed in a horizontal direction from the position.

  By adopting such a configuration, the transfer table can be moved in the horizontal direction to the position where the cutting unit is exposed. Therefore, maintenance of the cutting unit is possible without being submerged below the transfer table, and workability is improved. Improvements can be made. In addition, the transfer table is configured to reciprocate in the horizontal direction when the bread is cut, but in this way, the output torque of the drive source (for example, an electric motor) is compared with the case where the transfer table is operated in the vertical direction. Therefore, it is possible to use a small and inexpensive drive source. Further, since the transfer table is moved, the position of the cutting part can be fixed, and safety can be improved.

  In addition, it further includes a projecting dimension restricting part that abuts the downstream end surface of the bread pan and restricts the projecting dimension of the bread pan from the downstream end of the transfer table, and the cutting unit is configured to move the transfer table during the reciprocating operation of the transfer table. It may have a round blade which is located between the downstream end and the protruding dimension restricting portion and cuts the protruding portion of the bread from the downstream end of the transfer table. By setting it as such a structure, the bread piece which has fixed thickness and a smooth cut surface can be obtained.

  Moreover, you may further provide the bread piece delivery part which receives the bread piece obtained by cut | disconnecting bread with the said round blade, and moves this bread piece to a predetermined position further. By setting it as such a structure, in order to perform the following process (for example, cutting of an ear | edge part) to the bread piece after a cutting | disconnection, it is possible to deliver to predetermined positions, such as on a conveyance conveyor.

  In addition, the cutting unit has a peeling unit that enters the cut during the cutting of the bread with the round blade and peels the bread pieces from the bread, and the bread piece delivery unit accommodates the bread pieces peeled from the bread. A bread piece receiving portion, and a displacement portion for displacing the bread piece receiving portion, the displacement portion receiving a bread piece, and a discharging position for discharging the received bread piece to the predetermined position. The bread piece receiving part may be displaced between the two. With this configuration, the bread piece received at the receiving position can be discharged at the discharge position, and the bread piece can be delivered to a predetermined position.

  In addition, the bread piece receiving portion has a first support surface that is horizontal to support the lower surface of the bread piece at the receiving position, and the first support surface to support a surface opposite to the cut surface of the bread piece. A second support surface erected on the first support surface, and an open portion that is located above the first support surface and that opens the top of the bread piece, and at the discharge position, the open portion is more than the first support surface. The second support surface may be configured to be inclined and inclined. With such a configuration, the bread piece can be discharged from the opening portion at the discharge position while the bread piece is reliably supported and received by the first support surface and the second support surface at the reception position. In addition, the bread piece receiving portion can be realized with a simple configuration in this way.

  Moreover, the said bread piece receiving part may be comprised so that a said 2nd support surface may follow the said peeling part in the said receiving position. By setting it as such a structure, the bread piece peeled from the bread by the peeling part can be reliably supported by the 2nd support surface.

  According to the bread cutting device according to the present invention, it is possible to reduce the size and the price, and to improve the maintainability.

The bread piece housing portion 51, in a state located in the receiving position P _3, is constituted by three supporting surfaces 51a~51c provided so as to be perpendicular to each other.

  Of these, the first support surface 51a is horizontal to support the lower surface of the cut bread piece 1B, and has a trapezoidal shape with a size larger than the lower surface of the bread piece 1B. The second support surface 51b has a square shape larger than this surface so as to support the surface opposite to the cut surface of the bread piece 1B (that is, the surface that is in contact with the contact plate 23a at the time of cutting). And is erected so as to be orthogonal to the first support surface 51a. The third support surface 51c has a rectangular shape larger than this surface so as to support the right side surface of the bread piece 1B, and is orthogonal to both the first support surface 51a and the second support surface 51b. The first support surface 51a is erected. Furthermore, the upper part of the first support surface 51a is open, forming an open part 51d.

Thereby, the bread piece 1B in the bread piece accommodating part 51 is discharged | emitted to a predetermined position from the open part 51d outside along the 2nd support surface 51b.

[Explanation of the operation of the bread cutting device]
The bread bread cutting device 3 having the configuration as described above sequentially cuts (slices) the bread 1A supplied from the downstream conveyor 11 from its front portion, and the bread pieces 1B to the ear cutting device 4 in the next process. Perform a series of tasks of passing. And more specifically about this series of operations, when the transfer table 21 is positioned at the supply position P _1, bread 1A is supplied to the motion stage 21 from the downstream side conveyor 11 by extrusion mechanism 11c. The bread 1 </ b> A on the transfer table 21 is transferred forward by the pusher 22 a of the movement drive unit 22 and is brought into contact with the abutment plate 23 a of the protruding dimension regulating unit 23 at a preset position.

Next, the transfer table 21 is horizontally moved from the position P ₁ to the position P ₂ by driving the reciprocating drive unit 30. As a result, the bread 1 </ b> A approaches the round blade 41 that is rotated by driving the cutting unit 40, and the protruding portion from the downstream end of the transfer table 21 is cut by the round blade 41 from the right side of the bread 1 </ b> A. . Further, during the cutting of the bread 1A, the acute angle portion 43b of the peeling portion 43 enters the cut end, and the protruding portion of the bread 1A being cut is separated from the remaining bread 1A. Then, the protruding portion will be disconnected from the bread 1A is guided along the peeling unit 43, will be housed in the pan piece housing portion 51 of the pan piece transfer part 50 having been positioned in the accommodation position P _3.

When the transfer table 21 reaches the position P ₂ through such a cutting operation, the protruding portion of the bread loaf 1A is completely cut to obtain the bread piece 1B, and the bread piece 1B is accommodated in the bread piece accommodating portion 51. The Furthermore, by the displacement unit 52 of the pan piece transfer unit 50 is driven, the pan piece housing portion 51 revolves around the transmission shaft 52 b, is displaced from the housed position P3 to the discharge position P _4. As a result, the pan pieces 1B is discharged from the pan piece housing portion 51 at the discharge position P _4, the ear cutting device 4 which will be described is adapted to be passed at a predetermined position of the mounting table 103 provided in the.

Also, when one pan piece 1B is obtained by cutting, the transfer table 21 is returned to the position P _1, is transferred to the front until it abuts against the contact plate 23a by the pushing of the pusher 22a. Then, when the transfer table 21 is moved again from the position P ₁ to the position P ₂ , the protruding portion of the bread 1A is cut to form the next bread piece 1B. When such cutting of the bread 1A is repeated and all bread pieces 1B cut from one bread 1A are obtained, the transfer table 21 is returned to the position P ₁ and the transfer drive unit 22 is moved during the movement. The pusher 22a is raised and retracted and returned to the initial position. Then, the transfer table 21 reaches a position P _1, then bread 1A that was on the downstream side conveyor 11 to be cut is to be supplied to the motion stage 21 by extrusion mechanism 11c.

  Such a bread cutting device 3 is configured such that a rotating round blade 41 is fixedly provided, and the transfer table 21 on which the bread 1A is placed moves relative thereto. Therefore, higher safety is ensured. In addition, since the transfer table 21 is configured to move in the horizontal direction, the output torque of the drive source (servo motor 31 in the present embodiment) can be smaller than that in the case of moving in the vertical direction, for example. Pricing is possible.

Furthermore, even when the entire apparatus is downsized, the space 45 is formed behind the round blade 41 by retracting the transfer table 21 to the position P ₁ in the horizontal direction with respect to the round blade 41. There is an advantage that maintenance such as replacement work of the round blade 41 can be easily performed through the space 45.

When the air is supplied to the actuator 131, the plunger 131 a advances downward and obliquely rearward, and accordingly, the front support member 134 also moves downward and obliquely rearward, and is a predetermined distance slightly upward from the upper surface of the endless transport sheet 112. Reach position. At this time, the rear end surface of the front support member 134 (the surface facing the bread piece 1B) abuts the front end surface of the bread piece 1B placed on the endless conveyance sheet 112, so that the bread piece 1B can be supported from the front. It has become. Further, since the front support member 134 is wider than the bread piece 1B, even if the bread piece 1B on the endless conveyance sheet 112 is slightly shifted left and right, it can be received and supported. Yes.

When exhausted from the actuator 131, the plunger 131 a moves backward obliquely forward, and accordingly, the front support member 134 also moves obliquely upward forward, and a predetermined height H from the upper surface of the endless transport sheet 112. To reach the position. Since this height H is higher than the height dimension (thickness) H _B of the bread piece 1B, the bread piece 1B (more accurately, by turning the endless conveying sheet 112 with the front support member 134 retracted). Even if the processed bread 1D) after cutting the ear portion 1C moves forward, the bread piece 1B can pass below the front support member 134 without contacting it.

  On the other hand, as shown in the front view of FIG. 8, the side support mechanism 104 b has a symmetrical configuration on the left and right sides, and an electric actuator 140 disposed below the seat support plate 114 and the actuator 140. Left and right side support members 141 that can be moved on the mounting surface 112a. More specifically, the actuator 140 has two plungers 140a and 140a that advance and retract simultaneously in opposite directions, and these plungers 140a are arranged to advance and retract in the left-right direction. That is, when both plungers 140a advance, the actuator 140 extends to the left and right outwards, and when both plungers 140a move backward, the actuator 140 contracts to the left and right inwards.

The blade support frame 165 has a rectangular shape in plan view and is provided upright from a main surface plate 165a provided in parallel to the placement surface 112a of the endless conveyance sheet 112, and left and right sides of the main surface plate 165a. The side plate 165b has a rectangular shape that is long in the front-rear direction. And the lower end part of the transmission rod 164 is pivotally supported in the center position of the front-back direction in this side plate 165b (refer FIG. 7).

As shown in FIG. 7, the blade support frame 165 is also supported by a guide portion 167 provided on the frame body 6. The guide portion 167 includes a guide rod 167a extending in the vertical direction, and a rod receiving portion 167b through which the guide rod 167a is inserted and sliding in the vertical direction along the guide rod 167a. As shown in FIGS. 7 and 8, the guide rods 167a, in the ear cutting device 2 group 4 so as to surround the cut position P ₅ to cut the ear 1C bread piece 1B, its front left and right and rear left and right A total of four are arranged. The rod receiving portions 167b are respectively provided on the front and rear sides of the left and right side plates 165b of the blade support frame 165 corresponding to the four guide rods 167a.

  Four cutting blades 150 are attached to the lower surface of the main surface plate 165 a of the blade support frame 165 via a bracket 170. As shown in FIG. 10, the cutting blade 150 is disposed opposite to the front and rear and a pair of long cutting blades 150 a for cutting the front and rear ear portions 1 </ b> C of the bread piece 1 </ b> B. It has a pair of short cutting blades 150b for cutting the left and right ear portions 1C of 1B. The short cutting blade 150b is disposed between the pair of long cutting blades 150a.

  11 is a cross-sectional view showing a configuration when the cutting blade 150 is cut along the XI-XI line parallel to the long cutting blade 150a shown in FIG. 10, and FIG. 12 is a short cutting shown in FIG. It is sectional drawing which shows a structure when the cutting blade 150 is cut | disconnected along the XII-XII line | wire parallel to the blade 150b.

  As shown in FIG. 11, the long cutting blade 150a has a horizontally long rectangular shape, and a double-edged blade 171 is formed on the lower side of the long cutting blade 150a so that the cutting edge 171a is a straight line parallel to the mounting surface 112a. Has been. Further, through holes 172 are formed on the left and right of the upper part, respectively, and the long cutting blade 150a is set up vertically and the cutting edge 171a is in a posture along the left and right direction (direction perpendicular to the conveying direction). The bolt 170 is fastened to the bracket 170 through 172.

As shown in FIG. 12, the short cutting blade 150b has the same height dimension as the long cutting blade 150a, the upper part is rectangular, and the lower part is an isosceles table whose width dimension increases toward the lower side. The lower end 175 has an acute angle A ₁ when viewed from the normal direction. Then, the angle A ₁ of the lower ends 175, opposing surface 171b of the blade 171 of the elongate cutting blade 150a that are opposed is set to be smaller than the angle A ₂ to form with respect to a horizontal plane. The blade 173 at the lower side of the short cutting blade 150b is also a double-edged type, and the blade edge 173a is formed in a straight line parallel to the placement surface 112a. Further, through holes 174 are formed on the upper left and right, respectively, and the short cutting blade 150b is set up vertically and the cutting edge 173a is in a posture along the front-rear direction (conveying direction). The bolt is fastened.

In this way, the long cutting blade 150a and the short cutting blade 150b fixed to the bracket 170 have their respective blade edges 171a and 173a parallel to the placement surface 112a of the endless conveying sheet 112 and are positioned at the same height. is doing. Further, both ends of the cutting edge 173a of the short cutting blade 150b are in contact with the opposing surfaces 171b and 171b (see FIG. 12) of the blade 171 of the pair of long cutting blades 150a at right angles. Here, since both ends 175 of the blade 173 of the short cutting blade 150b are formed at an acute angle A ₁ (<A ₂ ) as described above, the cutting edge 173a of the short cutting blade 150b and the long cutting blade 150a The cutting edge 171a is continuously connected to each other, and the connecting portion between the two cutting edges 171a and 173a intersects at right angles with no gap as much as possible. As a result, the cutting edges 171a and 173a are arranged so as to form four rectangular sides that are smaller than the bread pieces 1B.

Meanwhile, as shown in FIG. 10, left and right (the length of the cutting edge 171a) dimension L ₃ of the elongate cutting blade 150a is greater than the dimension W _B of one side of the pan pieces 1B, the length dimension of the front supporting member 134 L ₁ and are substantially the same. L ₄ (length of the cutting edge 173a) longitudinal dimension of the part length cutting blade 150b is smaller than the dimension W _B of one side of the pan pieces 1B, with and slightly larger than the length L ₂ of the side support members 141 Yes. That is, the pair of front and rear long cutting blades 150a sandwiching the short cutting blade 150b has a distance between each other (= front-rear direction dimension L ₄ of the short cutting blade 150b) is the length dimension of the side support member 141. is larger than L _2, as shown in FIG. 10, elongate cutting blade 150a is located on the rear side than the front side and the rear end from the front end of the side support members 141. Therefore, even if the side support member 141 moves toward the center in the left-right direction, it only enters between the front and rear long cutting blades 150a and does not come into contact therewith (in FIG. (Refer to the side support member 141 indicated by a dotted line.)

  In the ear cutting mechanism 105, when the motor 151 is driven and the output shaft 153 rotates, the rotational motion is converted into a linear reciprocating motion in the vertical direction via the crank 162. This reciprocating motion in the vertical direction is transmitted to the cutting blade 150 supported by the blade support frame 165 via the transmission rod 164, and the four cutting blades 150 (150a, 150b) simultaneously move up and down with a predetermined stroke. Reciprocates. When the cutting blade 150 reaches the lowermost position, the cutting edges 171a and 173a come into contact with the placement surface 112a of the endless transport sheet 112, and when the cutting edge 150 reaches the uppermost position, the cutting edges 171a and 173a are the bread pieces 1B. It is located above the upper surface of.

[Operation of ear cutting device]
As shown in FIGS. 6 to 8, in the ear cutting device 4 as described above, the endless transport sheet 112 is rotated by the motor 113 included in the transport mechanism 110 and is placed on the placement surface 112a. The bread piece 1B is conveyed toward the front. When the bread piece 1B reaches a predetermined cutting position P ₅ (see FIG. 6), the transport mechanism 110 is temporarily stopped. Incidentally, as shown in FIG. 6, the rear vicinity of the cutting position P ₅ is sensor 180 consisting of a light emitting portion 180a disposed opposite each other across the endless conveying sheet 112 and the light receiving portion 180b is provided. Then, it has become possible to detect that the pan piece 1B has reached the cutting position P ₅ by the sensor 180, the transport mechanism 110 by detecting this is adapted to stop.

When the transport mechanism 110 pan piece 1B has reached the cutting position P ₅ is stopped, the support mechanism 104 is driven, the front support member 134 actuator 131 of the front support mechanism 104a is distracted support the front of the pan pieces 1B (See FIG. 9). Further, the actuator 140 of the side support mechanism 104b is reduced, and the side support member 141 supports the both sides of the bread piece 1B so as to sandwich the both sides. Accordingly, the pan pieces 1B, at the cutting position P _5, is supported from the front and both sides, is held in a predetermined posture.

Next, the motor 151 of the ear cutting mechanism 105 is rotationally driven in a state where the bread piece 1B is held in a predetermined posture. As a result, the cutting blade 150 (150a, 150b) located above in the initial state is lowered and cut so as to approach the bread piece 1B from above and beat the four ear portions 1C. A finished bread 1D is formed. Since elongated cutting blade 150a is elongated from the length W _B of one side of the pan pieces 1B, 4 sides of the ear portions 1C after cutting becomes each state separated from each other, before and after forming the elongated Ear portions 1C and left and right ear portions 1C that are relatively short are formed (see FIG. 1). And these ear | edge parts 1C will be in the state mounted in the mounting surface 112a of the endless conveyance sheet 112 so that the vicinity of 4 sides of processed bread | pan 1D may be followed.

  When the cutting of the ear portion 1C is completed, the cutting blade 150 is retracted upward by the rotational drive of the motor 151 of the ear cutting mechanism 105, and the support mechanism 104 is also driven to retract the front support member 134 and the side support member 141, respectively. . Next, the conveyance mechanism 110 is re-driven to rotate the endless conveyance sheet 112, and conveys the processed bread 1D and the ear portion 1C forward. The processed bread 1D that has been transferred moves to the driving conveyor 106 and is transferred further forward by the endless transfer sheet 116 for the next step.

Further, as already described, when the processed bread 1D moves from the transport mechanism 110 to the conveyor 106, it moves across the gap 119 between the transport mechanism 110 and the conveyor 106. Accordingly, the ear portions 1C that existed before and after the processed bread 1D during conveyance by the conveyance mechanism 110 fall downward from the gap 119. Further, the width W ₂ of the endless conveying sheet 116 of the conveyor 106, since that is substantially the same as the dimension W _D of one side of the processed bread 1D, present in the left and right machined pan 1D during conveyance by the conveying mechanism 110 The ear portion 1 </ b> C that has been used cannot be transferred to the conveyor 106, and these also fall downward. As described above, when the processed bread 1D moves from the transport mechanism 110 to the conveyor 106, none of the four ear portions 1C can be transferred to the conveyor 106, and falls downward and is separated from the processed bread 1D. It has become so.

  Thus, the bread piece 1B conveyed by the conveyance mechanism 110 is supported by the support mechanism 104, and the ear portion 1C is accurately cut by the ear cutting mechanism 105 to form a processed bread 1D. Further, when being conveyed to the conveyor 106, the ear portion 1C is separated from the processed bread 1D, and only the processed bread 1D can be obtained.

  As is clear from the above description, according to the ear cutting device 4 according to the present embodiment, the cutting blades 150 (150a, 150b) have a rectangular shape corresponding to each of the four sides of the bread piece 1B. Since it is disposed, all the ear portions 1C of the bread piece 1B can be excised at a time, and the apparatus can be reduced in size and cost. Further, since the ear portion 1C is excised as if it is beaten by the cutting blade 150 descending from above, the bread piece 1B is not pulled in the longitudinal direction of each side at the time of cutting (as when using a round blade). . Therefore, processed bread 1D (sandwich bread) having a corner portion of approximately 90 degrees can be manufactured, and the merchantability can be improved.

  Then, by combining the bread cutting device 3 already described and the ear cutting device 4 to configure the bread processing device 1, the bread 1A is sliced into bread pieces 1B having a certain thickness, and the ear portion 1C is further excised. As a device that can automatically manufacture processed bread 1D for sandwiches, it is possible to provide an unprecedented miniaturized and low-priced device, and easy maintenance of the round blade 41 for slicing is possible. Can be realized.
