Description

Application of Article 30, Paragraph 2 of the Patent Act [Exhibition date] June 12-15, 2018 [Exhibition name] FOOMA JAPAN 2018 (International Food Industry Exhibition) [Exhibition location] Tokyo Big Sight East Halls 1-8 ( 3-10-1 Ariake, Koto-ku, Tokyo)

The present invention relates to a molder used in shaping processes such as confectionery and bread lines.

In a confectionery and bread line, etc., a molder is used in a forming process for fermenting dough kneaded with raw material flour, dividing the dough into predetermined sizes, and then flattening the rounded dough to a predetermined thickness. . This molder is also called a shaping machine, and puts the rounded dough between a pair of rolls opposed to each other and shapes it so that it is flat and has a predetermined thickness. Since it is not possible to shape the dough to a predetermined thickness without damaging the dough only by passing it through a pair of rolls only once, it is usually between multiple pairs of rolls whose intervals are gradually narrowed, for example, a three-roll type moulder. A flattened dough of the desired thickness is obtained, sometimes by passing it between three pairs of rolls. These three pairs of rolls are called 1st roll, 2nd roll, and 3rd roll in order from the highest pair. Rotate. Since the pair of rolls are rotating toward each other, the dough put between the pair of rolls is compressed to the thickness of the gap distance between the pair of rolls and falls down to the next downward position. After passing through the process of feeding between a pair of rolls three times, the dough is shaped to the optimum thickness and size without damaging it, and then conveyed to the next process by a conveyor (for example, Patent Document 1). Since the dough has stickiness, powder is sprinkled to prevent it from adhering to the roll, but a scraper is provided close to the roll at a predetermined distance to scrape off the adhering dough.

Japanese Patent Publication No. 61-035807

Since the outer peripheral surface of the roll is coated with chrome plating or Teflon (registered trademark), the gap between the paired rolls is gradually increased due to wear due to long-term use, and furthermore, the rolls are damaged. In order to prevent a good thickness from being obtained, adjustment is made by rotating the lever of the roll gap distance adjustment device provided on the frame, but if the adjustment limit is exceeded, chrome plating or Teflon-coated rolls must be replaced. Since it is the final stage roll, for example, the third stage roll, that wears the Teflon more severely, the work of replacing this third stage roll is the most frequent. When replacing this, the front side roll of each stage is removed from the frame using a tool, then the back side roll is removed, and then the new roll is installed in the reverse order. The number of steps is large, and it takes several hours or more just to replace a pair of rolls in each stage. In addition, there was a problem that the confectionery and bread line had to be stopped because the molder could not be used during the replacement work.

The present invention has been made in view of the above-mentioned circumstances, and the means thereof is to ferment the kneaded dough, divide it into predetermined sizes, and then flatten the rolled dough to a predetermined thickness. A corrugating roll unit having two back side rolls and a front side roll which are opposed to each other with a predetermined distance and are rotationally driven are provided in a frame body in multiple stages in the vertical direction, and each of the multi-stage corrugating roll units are independently detachably fixed to the frame , the bottom roll unit of each of the multi-level roll units is separated into a back roll unit and a front roll unit, each independently and is independently and removably fixed to the frame .

Each unit frame for rotatably supporting the rotation shafts of the back roll and the front roll of each roll unit except for the bottom roll unit can be attached to and detached from the frame by being inclined so that the front roll side is positioned upward. It has to do with a fixed moulder.

Detachable fixation of each of the unit frames except for the lowest stage to the frame is achieved by the stepped portion formed on the slanted surface of the slanted frame, and the reverse stepped portion formed on the inner end surface of each unit frame. The moulder is mounted and fastened by a mounting bolt penetrating through the inclined frame so that the rear end surface is in close contact with the inclined surface of the inclined frame.

The detachable fixation of the inner roll unit and the front roll unit of the lowermost roll unit to the frame is a molder that fixes the lower side of the inner roll unit and the front roll unit to the frame with a fixture. That's what it is.

The back side roll unit and the front side roll unit of the lowermost roll unit are moulders placed slidably on guide rails provided in the front-rear direction of the frame.

According to the molder of the present invention, each corrugating roll unit is independently and removably fixed to the frame, so that each corrugating roll unit can be removed. For this reason, when the coating material coated with chrome plating, Teflon (registered trademark), etc. on the outer peripheral surface of the roll wears out and the roll is replaced, only the corresponding corrugating roll unit is removed from the frame and the coating material is removed in advance. Since each corrugating roll unit with repaired rolls can be fitted, the replacement work can be done in a very short time. Therefore, the time for stopping the confectionery and bread production line can be saved, and as a result, the efficiency of manufacturing the confectionery and bread can be improved. In addition, since the rolls of each corrugating roll unit can be replaced by transporting them to a well-equipped repair shop, the work efficiency is improved and the work is easy. In addition, the bottom roll unit is separated into a back roll unit and a front roll unit, and the back roll and the front roll are driven independently by separate drive sources, so the fabric is not damaged. thickness can be obtained. In addition, since they are separately fixed to the frame in a detachable manner, they are light as a single unit and easy to work.

A unit frame that rotatably supports the roll shafts of the back and front rolls of each of the multi-level roll units except for the bottom roll is inclined with respect to the frame so that the front roll is positioned upward. Since it is fixed, it can be lifted obliquely upwards or lowered obliquely downwards during the attachment/detachment work, which facilitates the work.

Each of the roll units except for the bottom of the multi-stage roll units is fixed to the frame body by forming a reverse step portion formed at the back end of each unit frame on the inclined surface of the inclined frame body. Since it can be placed on the part, positioning is easy, and since the weight is received by the stepped part, the work can be facilitated. Furthermore, the operation is simple because it is only necessary to tighten so that the rear end surface of the bolt inserted by the mounting bolt that penetrates the tilt frame and the tilt surface of the tilt frame are in close contact with each other. In addition, since the removal can be performed by the reverse process, the work is easy.

Since the rear roll unit and the front roll unit of the bottom roll unit are installed on the guide rails provided in the front-rear direction of the frame, they slide on the guide rails without being lifted when attaching to or detaching from the frame. Since it can be installed and removed just by putting it on, the attachment and detachment work is easy.

Since the front side roll unit and the back side unit that constitute the bottom roll unit are fixed to the frame by fixing tools such as bolts from below the frame that constitutes the guide rail, Installation and removal work is easy.

BEST MODE FOR CARRYING OUT THE INVENTION The best mode for carrying out the invention will be described below with reference to the drawings. The molder 1 of this embodiment, as shown in FIG. The roll unit 5 is installed at an angle while shifting its position forward, and machinery is stored in the lower half of the frame 2. - 特許庁Above the frame 1, the tip of a dough carrying-in conveyor 6 for carrying in the dough A rounded by a rounding machine (not shown), which is the previous process of the previous confectionery and bread line, is shown in FIG. It is arranged to be positioned above the first roll unit 3, and below the tip of the third roll unit 5 in the vicinity of the center of the frame 2, the shaped dough A is conveyed to the next confectionery and bread line. A dough unloading conveyor 7 is installed through the frame body 1 so that a placement surface 7a moves from the rear to the front. Further, an upper powder sifter 8 is installed above the first-stage roll unit 3 of the frame 2, and powder is supplied above the three-stage roll unit 5 above the dough carrying-out conveyor 7 of the frame 2. A powder feed conveyor 10 is installed to sprinkle the powder discharged from the lower powder sifter 9 above the three-stage roll unit 5 . The thickness of the cloth A to be fed into the first roll unit 3 is reduced by lightly pressing the cloth A which has been rounded and conveyed above the tip side of the cloth carrying-in conveyor 6 above the frame 2. A preload roll device 11 is provided.

As shown in FIGS. 5 and 7, the first-stage roll unit 3 is rotatably supported at both ends of a rotating shaft 32 by a first-stage unit frame 31. The outer peripheral surface is coated with SS hard chromium plating or the like. A pair of rolls, a back side roll 33 and a front side roll 34, are installed with a predetermined pressure interval and are rotated in the directions in which the upper sides face each other. In addition, when the chrome plating coated on the outer peripheral surface of the front roll 34 is worn out, the pressure gap can be adjusted by approaching the back roll 33. A first-stage adjusting mechanism 35 is provided on the first-stage unit frame 31 . The first-stage adjusting mechanism 35 can be operated by rotating left and right adjusting levers 35a, which are projected from the front of the first-stage unit frame 31 and shown only in FIG. The two-stage roll unit 4 also has the same configuration except that the outer peripheral surfaces of the back roll 43 and the front roll 44 are coated with Teflon, which is a softer material than chrome plating. That is, when the front side roll 44 and the back side roll 43 are worn, the pressure interval can be adjusted by rotating the left and right adjustment levers 45a provided by projecting forward from the second stage adjustment mechanism 45. It's becoming

As shown in FIGS. 4 to 9, the three-stage roll unit 5 is separated into a back roll unit 5A and a front roll unit 5B. Both sides thereof are rotatably supported by the back side unit frame 51A, and both sides of the rotating shaft 52 of the front roll 54 of the front side roll unit 5B are rotatably supported by the front side unit frame 51B. In the front side roll unit 5B, a front side roll 54 paired with the back side roll 53 is installed so that the upper sides of the rolls 53 and 53 are rotated in opposite directions with a predetermined pressure interval. The pressing interval can be adjusted by rotating left and right adjustment levers 55a projecting forward from the front roll unit 5B of the third stage adjustment mechanism 55 provided in the front unit frame 51B.

The first roll unit 3, the second roll unit 4 and the third roll unit 5, as shown particularly well in FIG. Since the lines connecting the centers of the back side roll and the front side roll are fixed so as to be perpendicular to each other, the roll units 3, 4 and 5 of each stage are inclined so that the front side faces upward. Further, as can be seen from FIG. 4 , the rotation shafts 32 , 32 , 42 of the respective four rolls of the inner rolls 33 , 43 and the front rolls 34 , 44 of the one-step roll unit 3 and the two-step roll unit 4 , 42 is rotationally driven by transmitting a belt 15 to one first drive source 14 by appropriately winding an auxiliary roll 16 so that the rotation directions of the rolls match. The back side roll unit 5A and the front side roll unit 5B of the three-stage roll unit 5 are driven by the belts 15 transmitted from the independent second drive source 18 and third drive source 17, respectively. The third drive source 17 of the front roll unit 5B is provided on the same side as the first drive source 14, and the third drive source 18 of the back roll unit 5A is provided on the opposite side as shown in FIG. ing. The reason why the inner roll unit 5A and the front roll unit 5B of the three-stage roll unit 5 are provided with separate drive sources is that the fabric A needs to be spread more smoothly and thinly.

Attachment of each corrugating roll unit 3, 4, 5 to the inclined surface 13a of the inclined frame 13 will be described below with reference to FIGS. 5 and 8 to 10. FIG.
The inclined frame 13 of the first-stage roll unit 3 is fixed to the inclined surface 13a by screwing the inclined frame 13 laterally into the bolt hole 31a formed in the inner end surface of the first-stage unit frame 31 of the first-stage roll unit 3. A mounting bolt 20 with a hexagonal hole or the like is inserted from the side of the frame 2 by using an appropriate tool B through the insertion hole 19a that penetrates the tilt frame 13 from the side of the slant frame 13 in the recess 19 formed in the side surface. by rotating and screwing and tightening. The mounting bolts 20 are tightened at four points by inserting them from four depressions 19 formed two by two in the vertical direction on both lateral sides of the inclined frame 13 of each stage of the roll unit. ing. A reverse stepped portion 31b is formed on the inner side surface of the first-step unit frame 31 of the one-step roll unit 3, and a stepped portion 13b on the inclined surface 13a of the inclined frame body 13 forms a pair with the reverse stepped portion 31b. By placing the opposite stepped portion 31b on the stepped portion 13b, the through hole 19a and the bolt hole 31a are aligned so that the mounting bolt 20 can be inserted from the side of the recessed portion 19 through the through hole 19a. It facilitates screwing into the bolt hole 31a and also supports the weight of the first roll unit 3. As shown in FIG. The attachment of the first-stage roll unit 3 to the frame 2 has been described above, but the same applies to the attachment of the second-stage roll unit 4 to the frame 2, so a description thereof will be omitted.

The three-stage unit 5 is fixed to the frame 2 by penetrating the guide rail 21 from below the guide rail 21 of the frame 2 on which the rear roll unit 5A and the front roll unit 5B are independently mounted. Mounting bolts 22 are screwed into bolt holes (not shown) formed in the bottom surfaces of the three-stage back roll unit 5A and the front roll unit 5B through the through holes 21a. At this time, the reverse stepped portion 51b formed on the end face on the far side of the far side unit frame 51A of the far side roll unit 5A is positioned at the lowest position formed on the inclined surface 13a of the inclined frame 13 of the frame 2. It is stably placed on the stepped portion 13b. As shown in FIG. 7, a scraper 23 for scraping off the dough A adhering to the surfaces of the pair of rolls facing each other of the roll units 3, 4 and 5 of each stage is provided in the roll units in the vicinity of each roll. It is

As shown in FIG. 4, a total of four rolls, ie, the first roll unit 3 and the second roll unit 4, are rotated by a belt 15 wound around one first drive source 14, which transmits the rotary force. . In each of the back side rolls 33, 43, 53 and the front side rolls 34, 44, 54 of each of the roll units 3, 4, 5 from 1 to 3 steps, the 3-step unit 5 is the final shaping, and the speed difference In order to spread the dough more smoothly and thinly, the back side roll 53 and the front side roll 54 are adapted to receive rotational forces from separate drive sources 17 and 18 via separate belts 15. - 特許庁The reason why the third drive source 18 of the back side roll 54 is on the opposite side is because of the installation space.

The operation of the molder 1 according to the embodiment of the present invention having the above configuration will be described. As shown in FIGS. 1 to 5, the round dough A conveyed by the dough carrying-in conveyor 6 from the rounding machine (not shown) of the previous confectionery and bread line is slightly flattened by the pre-pressure roll device 11 immediately before being carried out. After being pressed from the first roll unit 3 , it is put into the upper part between the back side roll 33 and the front side roll 34 of the one-stage roll unit 3 . During this time, the powder sprinkled from the upper powder sifter 8 is dispersed and dropped on the surfaces of both rolls 33 and 34, so that it does not adhere to the roll surfaces. is scraped off by a scraper 23 provided with a predetermined gap from the surface of the . The scraper 23 is also provided on each of the second and third rolls to scrape off the dough A adhering to the surface thereof. The fabric A is sandwiched between the rolls 33 and 34, stretched to a thickness equal to the distance between the rolls 33 and 34, flattened, and shaped obliquely downward. is dropped upward between the back side roll 43 and the front side roll 44 of the two-stage roll unit 4 located at . The distance between the rolls 43 and 44 of the two-step roll unit 4 is slightly narrower than the distance between the rolls 33 and 34 of the one-step roll unit 3, and the pressure between the rolls 53 and 54 of the three-step roll unit 5 is small. is narrower than the pressing distance between the two rolls 43 and 44 of the two-stage roll unit 4, the dough A, which is gradually pressed thinly and widely, finally reaches the dough carrying-out conveyor 7. It is dropped and mounted above the mounting surface 7a and conveyed to the next process.

By repeating the above operation continuously for a long period of time, the coating material on the outer peripheral surfaces of the paired rolls 33, 34, 43, 44, 53, 54 of the roll units 3, 4, 5 of each stage is worn. In this case, the adjustment levers 35a, 45a, and 55a of each stage are operated to adjust the pressing interval to an appropriate distance. However, if the wear exceeds the adjustment limit or if the roll surface is damaged and the thickness is no longer in good condition, the roll must be replaced. This replacement work is performed independently for each stage. Since the first roll unit 3 and the second roll unit 4 are replaced with each other in the same manner, the two roll units have the same structure. Therefore, only replacement of the first-stage roll unit 3 will be described, and replacement of the second-stage roll unit 4 will be omitted.

To replace the one-stage roll unit 3, after removing the belt 15 wound around the rotating shaft 32 of each roll 33, 34 shown in FIG. A tool B for rotating the mounting bolts 20 is sequentially inserted into the four depressions 19 from the side of the frame 2 to release the connection between the inclined frame 13 and the first roll unit 3 . At this time, the 1st roll unit 3 is supported from both sides by using a take-out holding device (not shown) so that it does not drop from above the 2nd roll unit 4 due to its own weight. It is only necessary to take out the device while lifting it obliquely upward in the direction of arrow B shown. After that, it is transported to a repair shop or the like, and the chrome plating coated on the surfaces of both rolls 34 and 35 and the Teflon in the case of the two-stage and three-stage roll units 4 and 5 are removed from each roll and coated again. At the same time, the scraper 23 is adjusted to prepare for the next use. After the detachment, the one-stage roll unit 3 that has been prepared in advance is moved from the obliquely upward direction to the inclined surface 13a of the inclined frame 13 by using the take-out and holding device described above, via the upper side of the two-stage roll unit 4. After placing the opposite stepped portion 31b formed on the inner side surface of the one-step roll unit 3 on the stepped portion 13b and positioning it, the mounting bolts 20 are sequentially inserted into the four recessed portions 19 and passed through the insertion holes 19a to insert the one-step roll. It is inserted into the bolt hole 31a of the unit 3 and fixed by tightening.

Detachment and attachment of the two-stage roll unit 4 are the same as those of the one-stage roll unit 3 except that the outer peripheral surface of the roll is made of Teflon, so the description thereof will be omitted.

Since the three-stage roll unit 5 is separated into a back side roll unit 5A and a front side roll unit 5B, these units 5A and 5B are laid in parallel on both sides of the fabric carry-out conveyor 7 provided in the frame 2. It is fixed on the guide rail 21 which is installed. As shown in FIGS. 4 and 9, the rear roll unit 5A and the front roll unit 5B are fixed from below the guide rail 21 to the lower surfaces of the rear unit frame 51A and the front unit frame 51B of the roll units 5A and 5B. A mounting bolt 22 passing through a hole 21a is screwed into the provided screw hole and tightened. At this time, the reverse stepped portion 51b formed on the inner side surface of the inner side unit frame 51A of the inner roll unit 5A is placed on the stepped portion 15b provided on the inclined surface 13a of the inclined frame 13 .

Therefore, when removing the three-stage roll unit 5, the mounting bolts 22 fixing the back roll unit 5A and the front roll unit 5B are removed, and then the front roll unit 5B is guided in the conveying direction of the dough unloading conveyor 7. After sliding it on the rail 21, it is removed from the frame 2 by a lift-mounting device (not shown), and then the rear roll unit 5A is removed from the frame 2 in the same procedure. After that, the inner roll unit 5A and the front roll unit 5B, which have been previously coated with Teflon on the two rolls 53 and 54 and have finished adjusting the clearance between the scrapers 23, are slid on the guide rails 21 in this order to remove the inner rolls. After pushing until the reverse stepped portion 51b of the unit 5A and the third stepped portion 15b from above the inclined surface 13a of the inclined frame 13 engage with each other, the front side roll unit 5B is brought into close contact with the back side roll unit 5A and guided. The rails 21 are fixed to the frame 2 by inserting mounting bolts 22 into the respective bolt holes from below and screwing them.
In the above embodiment, an example using a three-stage roll unit was described, but the same applies to a molder using a two-stage roll unit or a four-stage roll unit or more. Only the bottom roll unit can be attached and detached by sliding on the guide rail. Also, it can be used for shaping of dough other than the confectionery and bread line.

In the manner described above, each of the roll units 3, 4, 5 of tiers 1 to 3 can be independently replaced with a new, repaired roll unit. Therefore, in the past, the replacement work was done at the site where the confectionery and bread production line was installed, which was a difficult task that took a long time and required the production line to be stopped during the work. According to this invention, it is only necessary to remove the roll units of each required stage, transport them to a repair shop, and replace the corrected roll units. Since it is small, production loss can be minimized.

According to the molder of the present invention, replacement work can be performed easily and in a short time, so that the stoppage time of the confectionery and bread line can be shortened, and the production capacity of confectionery and bread can be increased.
