Description

[Technical Field]

[0001] This invention relates to a reverse sheeter that rolls out food dough into a sheet. [Background technology]

[0002] There are various types of devices for rolling out food dough such as bread dough or noodle dough into sheets, including a manual reverse sheeter such as the one shown in Figures 7 and 8. This device has a pair of first and second lower rollers 2, 3, each rotatably supported at both ends by the first and second sides 1a, 1b, arranged between opposing first and second sides 1a, 1b of a rectangular frame 1 having rubber legs L. In Figure 7, the first lower roller 2 is arranged at the front side within the frame 1, and the second lower roller 3 is arranged at the back side, with the first and second lower rollers 2, 3 arranged parallel to each other in the horizontal direction.

[0003] This device also includes first and second roller support plates 4a and 4b, an upper roller 5, and first and second positioning plates 6a and 6b. The first and second roller support plates 4a and 4b have their lower ends rotatably supported on the outer surfaces of the first and second sides 1a and 1b, respectively. The upper roller 5 is disposed between the first and second roller support plates 4a and 4b, and both ends of the upper roller 5 are rotatably supported by the first and second roller support plates 4a and 4b. The first and second positioning plates 6a and 6b have their lower ends rotatably supported on the outer surfaces of the first and second sides 1a and 1b, respectively. The first and second roller support plates 4a and 4b and the first and second positioning plates 6a and 6b intersect above the frame 1.

[0004] The first and second roller support plates 4a, 4b and the first and second positioning plates 6a, 6b are rotated to change a first intersection position between the first roller support plate 4a and the first positioning plate 6a and a second intersection position between the second roller support plate 4b and the second positioning plate 6b, thereby adjusting the height position of the upper roller 5. This allows the distance between the upper roller 5 and the first and second lower rollers 2, 3 in the height direction to be adjusted. A flat sheeter board 7 (see Figure 8) is placed on the pair of lower rollers 2, 3, and the food dough is rolled into a sheet between the upper roller 5, whose height has been adjusted as described above, and the sheeter board 7. The first lower roller 2 and upper roller 5 are connected by multiple gears (not shown) that are driven by a handle 8, and are driven simultaneously by operating the handle 8. The second lower roller 3 rotates in response to the movement of the sheeter board 7.

[0005] The first and second positioning plates 6a and 6b are formed with a plurality of positioning holes 10a and 10b and first and second guide holes 15a and 15b. The positioning holes 10a and 10b are formed continuously along the edges of the long sides of the first and second positioning plates 6a and 6b. The first and second guide holes 15a and 15b are formed along the plurality of positioning holes 10a and 10b. Corresponding to this configuration, first and second adjustment knobs 9a and 9b are provided at the intersections of the first and second roller support plates 4a and 4b with the first and second positioning plates 6a and 6b to adjust and fix the positions of the intersections. Although the second adjustment knob 9b is not shown in FIGS. 7 and 8, it is located directly opposite the first adjustment knob 9a across the frame 1.

[0006] The first and second adjusting knobs 9a and 9b are provided with positioning pins (not shown). The positioning pins penetrate the first and second roller support plates 4a and 4b, with their tips protruding from the inner surfaces of the first and second roller support plates 4a and 4b. The tips of each positioning pin are adapted to be inserted into one of the multiple positioning holes 10a and 10b in the first and second positioning plates 6a and 6b, respectively. The first and second adjusting knobs 9a and 9b are biased by elastic members such as springs (not shown) in a direction in which the tips of the positioning pins protrude into the positioning holes from the inner surfaces of the first and second roller support plates 4a and 4b.

[0007] Additionally, guide pins (not shown) are provided on the inner surfaces of the first and second roller support plates 4a and 4b near the positioning pins of the first and second adjusting knobs 9a and 9b. Each guide pin is inserted into the first and second guide holes 15a and 15b of the first and second positioning plates 6a and 6b, respectively, to guide the movement of the first and second roller support plates 4a and 4b relative to the first and second positioning plates 6a and 6b. With this configuration, the intersections can be fixed in optimal positions after the first and second roller support plates 4a and 4b are moved by inserting the tips of the positioning pins of the first and second adjusting knobs 9a and 9b into one of the multiple positioning holes 10a and 10b of the first and second positioning plates 6a and 6b, respectively. This changes the position of the intersection depending on the position of the positioning holes 10a and 10b into which the pins are inserted, thereby changing the height of the upper roller 5.

[0008] Furthermore, the support portions of the first and second positioning plates 6a and 6b are provided with first and second fine-adjustment positioning pins 11a and 11b, which penetrate positioning holes (not shown) formed in the first and second positioning plates 6a and 6b and the first and second sides 1a and 1b of the frame 1. The second fine-adjustment positioning pin 11b, also not shown, has a similar configuration to the first fine-adjustment positioning pin 11a and faces directly opposite the first fine-adjustment positioning pin 11a. The first and second fine-adjustment positioning pins 11a and 11b are also biased inward by an elastic member (not shown), such as a spring. Changing the insertion positions of the first and second fine-adjustment positioning pins 11a and 11b allows the positions of the first and second positioning plates 6a and 6b relative to the frame 1 to be changed. This allows the lower ends of the first and second positioning plates 6a and 6b to be slightly moved, thereby allowing the height position of the upper roller 5 to be finely adjusted.

[0009] A roller arm 13 is suspended between the first and second roller support plates 4a and 4b, and a positioning arm 14 is suspended between the first and second positioning plates 6a and 6b. A handle 12 is provided on the upper surface of the roller arm 13. [Prior art documents] [Patent documents]

[0010] [Patent Document 1] Retable 2019 / 230792 Summary of the Invention [Problem to be solved by the invention]

[0011] In the conventional reverse sheeter described above, when adjusting the height of the upper roller 5, the first and second roller support plates 4a and 4b must be rotated while releasing the intersecting portions to change the positions of the intersecting portions between the first and second roller support plates 4a and 4b and the first and second positioning plates 6a and 6b. To do this, the operator of the reverse sheeter must adjust the angle of the first and second roller support plates 4a and 4b while pulling the first and second adjustment knobs 9a and 9b outward to remove the positioning pins from the first and second positioning holes 10a and 10b. Therefore, the operator must move both hands in different directions while simultaneously opening them to adjust the angle. This makes adjusting the height of the upper roller 5 difficult.

[0012] Furthermore, when operating the first and second fine-adjustment positioning pins 11a, 11b, the operator must simultaneously move the first and second fine-adjustment positioning pins 11a, 11b outward while rotating the first and second positioning plates 6a, 6b, which is not an easy task. It is also possible to release the first and second roller support plates 4a, 4b and the first and second positioning plates 6a, 6b one at a time and then rotate them, but in this case, the operator must be careful to ensure that both sides are fixed in the same position, because if the fixing positions on both sides are misaligned, not only will the plates become twisted, but the thickness of the food dough sheet will also become uneven.

[0013] The object of this invention is to make it easy to adjust the height position of the upper roller. [Means for solving the problem]

[0024] [Configuration of the embodiment] An embodiment of the present invention will be described below with reference to FIGS. Fig. 1 is an external view of a reverse sheeter according to an embodiment.

[0025] The reverse seater of this embodiment includes a rectangular frame 1 formed by combining metal plates, as shown in Figure 1. A pair of opposing short sides of the rectangle that constitutes frame 1 are designated as a first side 1a and a second side 1b. In FIG. 1, components with the same reference numerals as those in FIGS. 7 and 8 showing conventional devices function in the same way as conventional devices, and are therefore given the same names.

[0026] Furthermore, the pairs of components arranged on the first and second sides 1a and 1b are in a plane-symmetrical relationship with respect to a vertical plane located in the center of the first side 1a and the second side 1b. The components on the first side 1a are denoted by a number and a, and the components on the second side 1b are denoted by a number and b. Detailed explanations of the same components as in the conventional technology will be omitted.

[0027] 1 to 3, the reverse sheeter of this embodiment has first and second lower rollers 2, 3 arranged at a distance between the first side 1a and the second side 1b. In this embodiment, the first lower roller 2 is provided near the connecting portion on the lower end sides of the first and second roller support plates 4a, 4b, and the second lower roller 3 is provided near the supporting portion on the lower end sides of the first and second positioning plates 6a, 6b.

[0028] Ring-shaped friction members 2a and 2b made of rubber or the like are attached to the surface of the first lower roller 2 to prevent slippage of a sheeter board 7 (see FIG. 8) placed on the first and second lower rollers 2 and 3 during use. In addition, the lower ends of the first roller support plate 4a and the first positioning plate 6a are rotatably connected to the first side 1a, and the upper ends of the first roller support plate 4a and the first positioning plate 6a intersect above the frame 1.

[0029] Similarly, the lower ends of the second roller support plate 4b and the second positioning plate 6b are rotatably connected to the second side 1b, and the upper ends of the second roller support plate 4b and the second positioning plate 6b intersect above the frame 1. An upper roller 5 is disposed between the first and second roller support plates 4a, 4b, and a roller arm 13 having a generally U-shaped cross section perpendicular to its length is hung from the upper end of the roller arm 5. A handle 12 is provided on the upper surface (outer surface) of the roller arm 13 in the longitudinal center.

[0030] A gear box 16 is attached to the outer surface of the first roller support plate 4a. A gear that rotates one of the lower rollers 2 and the upper roller 5 in the same direction is incorporated in this gear box 16, and a handle (not shown, corresponding to the handle 8 in FIG. 8) is attached so that the lower roller 2 and the upper roller 5 rotate in accordance with the rotation of the handle. The second lower roller 3 is free to rotate, and is pulled by the sheeter board 7 placed on top.

[0031] A positioning arm 14 is suspended across the upper ends of the first and second positioning plates 6a, 6b. As shown in Figures 2 and 3, each of the first and second positioning plates 6a, 6b is provided with a plurality of positioning holes 10a, 10b formed continuously in the length direction, and first and second guide holes 15a, 15b formed along the plurality of positioning holes 10a, 10b. On the other hand, each of the first and second roller support plates 4a, 4b has one positioning hole on the roller support plate side (not shown) formed at a position that can align with either of the positioning holes 10a, 10b when intersecting with the first and second positioning plates 6a, 6b.

[0032] As shown in FIGS. 2 and 3, a crossing position fixing connecting member 17 is provided on the lower surface of the roller arm 13 (the side opposite to the handle 12 or the inner surface). The intersecting position fixing connecting member 17 is made of a long plate member, and a main body portion 17c is disposed along the roller arm 13. First and second support pieces 17a, 17b are formed at both ends of the main body portion 17c. The first and second support pieces 17a, 17b are disposed by bending at a right angle from the end of the main body portion 17c toward the first and second roller support plates 4a, 4b. As shown in FIG. 2, the first support piece 17a is located inside the first roller support plate 4a, and its tip portion contacts the inner surface of the first positioning plate 6a. Meanwhile, as shown in FIGS. 1 and 3, the second support piece 17b protrudes outward from between the second roller support plate 4b and the roller arm 13 and contacts the outer surface of the second roller support plate 4b. The tip portion of the second support piece 17b is located at the intersection of the second roller support plate 4b and the second positioning plate 6a.

[0033] First and second fixing pins 18a and 18b, which are members for fixing the intersecting position, are provided on the first and second support pieces 17a and 17b with their tips facing in the same direction (see FIGS. 1, 2, and 4). The first fixing pin 18a passes through the first positioning hole 10a and the positioning hole of the first roller support plate 4a in that order, and the second fixing pin 18b passes through the positioning hole of the second roller support plate 4b and the second positioning hole 10b in that order, thereby fixing the position of the intersecting portion.

[0034] Furthermore, a lever 19 is provided inside the handle 12. A long hole 20 that guides the movement of the lever 19 is formed in the roller arm 13 (see Figure 4). One end of the lever 19 is fixed to the intersecting position fixing connecting member 17, and the other end is inserted into the long hole 20 and positioned inside the handle 12. As a result, when the lever 19 is operated along the long hole 20, the intersecting position fixing connecting member 17 also moves along the roller arm 13.

[0035] As shown in Fig. 3, a spring member 21 is provided inside the roller arm 13 to maintain the intersecting position fixing connecting member 17 in the position shown in Fig. 3. When the lever 19 is not operated, the spring member 21 biases the intersecting position fixing connecting member 17 in a direction that presses the support piece 17b against the second roller support plate 4b. This maintains the first and second fixing pins 18a, 18b inserted into the first and second positioning holes 10a, 10b. Note that symbol 22a in FIG. 1 and symbol 22b in FIG. 3 are first and second notches along the trajectory along which the rotation axis moves when adjusting the height position of the upper roller 5, and are intended to prevent the first side 1a and the second side 1b from interfering with the movement of the upper roller 5.

[0036] Next, the support portions of the first and second positioning plates 6a and 6b on the first and second sides 1a and 1b will be described.

[0037] The lower end of the first positioning plate 6a is rotatably supported by a first cam member 23a on the first side 1a. The first cam member 23a is a disk, cylinder, or the like, and is a member with a perfectly circular cross section. A first circular hole 24a that roughly coincides with the outer periphery of the first cam member 23a is formed on the lower end of the first positioning plate 6a, and the first cam member 23a is fitted into this first circular hole 24a. Therefore, the first positioning plate 6a can rotate around the first cam member 23a.

[0038] Similarly, on the second side 1b, the lower end side of a second positioning plate 6b is rotatably supported by a second cam member 23b having the same shape as the first cam member 23a. Also, a second circular hole 24b having the same shape as the first circular hole 24a is formed on the lower end side of the second positioning plate 6b, and the second cam member 23b is fitted into this second circular hole 24b. The first cam member 23a and the second cam member 23b, and the first circular hole 24a and the second circular hole 24b are opposed to each other and maintain a plane-symmetric relationship with the vertical plane located at the center of the first side 1a and the second side 1b as the reference plane. The relationship between the first and second cam members 23a and 23b and the first and second circular holes 24a and 24b is as shown in FIG.

[0039] 6, a shaft member 25, which is a positioning support portion connecting member (not shown in other figures), is fixed to a point P1 on the first cam member 23a that is eccentric from the outer circumferential circle thereof and the center O1 of the first circular hole 24a, and to a point P2 on the second cam member 23b that is eccentric from the outer circumferential circle thereof and the center O2 of the second circular hole 24b. This shaft member 25 penetrates the first and second sides 1a, 1b of the frame 1 and serves as the rotational center axis of the first and second cam members 23a, 23b, which rotate integrally. The shaft member 25 also serves as a rotation axis that rotatably supports the second lower roller 3 inside the frame 1.

[0040] 5, a generally cylindrical knob 26 is attached to the outside of the first cam member 23a. A protrusion 27 protruding in the radially outward direction is provided on the knob 26. The protrusion 27 extends outward from the peripheral side surface of the first positioning plate 6a, that is, to a position facing the first side 1a of the frame 1, and a fixing pin 28 is provided at its tip. The fixing pin 28 protrudes toward the first side 1a of the frame 1. Corresponding to the fixing pin 28, a plurality of positioning holes 29 are formed in the first side 1a of the frame 1 along the peripheral side surface of the first positioning plate 6a, through which the fixing pin 28 can be inserted.

[0041] Knob 26 is biased by an elastic member such as a spring (not shown) in the direction (inward) in which fixing pin 28 is inserted into positioning hole 29. By pulling knob 26 outward, fixing pin 28 can be pulled out of positioning hole 29, causing knob 26 to rotate about point P1, and first cam member 23a to rotate on a circular orbit centered on point P1. Therefore, first cam member 23a rotates about shaft member 25, i.e., performs eccentric motion.

[0042] When the first cam member 23a rotates, the second cam member 23b connected by the shaft member 25 also rotates. Therefore, the first and second cam members 23a and 23b simultaneously move eccentrically around the shaft member 25. When the first and second cam members 23a and 23b move eccentrically, the first and second circular holes 24a and 24b, indicated by solid lines in FIG. 6 and into which the first and second cam members 23a and 23b are fitted, move to the positions indicated by chain double-dashed lines as their outer peripheries move. In this way, the fixing pin 28 of the knob 26 can be inserted into one of the positioning holes 29 at an appropriate position while the first and second circular holes 24a and 24b move, thereby fixing the support portions of the moved first and second positioning plates 6a and 6b to the first and second sides 1a and 1b.

[0043] In other words, the fixing pin 28 is a support portion fixing member, and the knob 26 serves both as a support portion operating portion that moves the first and second support portions of the first and second positioning plates 6a, 6b, and as a fixing portion operating portion. By changing the positions of the support portions of the first and second positioning plates 6a, 6b, the intersection position and intersection angle of the intersection portion with the first and second roller support plates 4a, 4b are changed, and the height position of the upper roller 5 can be adjusted.

[0044] [Actions and effects] In the reverse sheeter of the above embodiment, the sheeter board 7 is placed on the first and second lower rollers 2, 3, and food dough such as bread dough is placed thereon. In this reverse sheeter, by gripping the handle 12 with one hand and operating the lever 19 with the fingers of that hand, the lever 19 can be moved in the direction of arrow x shown in Figure 4. When the intersecting position fixing connecting member 17 moves together with the lever 19, the first and second fixing pins 18a and 18b are simultaneously removed from the positioning holes 10a and 10b formed in the first and second positioning plates 6a and 6b, thereby releasing the intersecting portion. In this state, by moving the roller arm 13 with the handle 12, the angle of the first and second roller support plates 4a and 4b can be changed, thereby adjusting the height position of the upper roller 5. In other words, by gripping the device with one hand, the intersecting portion can be released by operating the lever 19, and further, the height position of the upper roller 5 can be adjusted by moving the roller arm 13. There is no need to operate the first and second adjustment knobs 9a, 9b simultaneously with both hands as in the conventional case, making height adjustment easier.

[0045] Furthermore, fine adjustments to change the positions of the support parts of the first and second positioning plates 6a and 6b can be made simply by operating the knob 26 on the first side 1a with one hand. In conventional devices, the first and second fine adjustment positioning pins 11a and 11b on both sides of the first side 1a and second side 1b of the frame 1 had to be operated separately with both hands and adjusted to the same position, but in the device of this embodiment, the positions of the first and second support parts of the first and second positioning plates 6a and 6b can be adjusted simultaneously by operating the knob 26 on the first side 1a with one hand only. Therefore, the height position of the upper roller 5 can be adjusted easily and accurately, and a food dough sheet having a uniform desired thickness can be produced with good workability.

[0046] In the reverse sheeter of the embodiment, the height of the upper roller 5 can be adjusted with one hand, leaving one hand free during the height position adjustment. Therefore, during the adjustment, there is a possibility that a finger may be inserted into the notches 22a, 22b formed in accordance with the movement trajectory of the rotation shaft of the upper roller 5. To prevent this, covers 30 as shown by the two-dot chain line in Figure 5 may be attached to the outside of the first and second sides 1a, 1b to cover the notches 22a, 22b.

[0047] In the above embodiment, the first and second cam members 23a, 23b are disk-shaped parts, but the pair of cam members need only be in contact with the inner peripheries of the first and second circular holes 24a, 24b formed in the first and second positioning plates 6a, 6b and move eccentrically, and are not limited to those with a circular outer periphery. Furthermore, the shaft member 25, which is the positioning support portion connecting member, only needs to enable the pair of cam members to operate integrally, and does not need to also serve as the rotation shaft of the second lower roller 3. However, if it also serves as the rotation shaft of the second lower roller 3 as described above, space can be saved and the device can be made compact.

[0048] In the above embodiment, the tips of the first and second fixing pins 18a, 18b are directed in the same direction and are moved in the same direction by operating the lever 19, but the mechanism for simultaneously moving the first and second fixing pins 18a, 18b is not limited to the above. For example, if the first and second fixing pins 18a, 18b are inserted into the positioning holes 10a, 10b from the outside and the support pieces 17a, 17b are simultaneously opened outward by operating the lever, the fixing on both sides can be released simultaneously. [Industrial Applicability]

[0049] The height position of the upper roller can be easily adjusted, allowing sheets of various food doughs to be formed with high precision. [Explanation of symbols]
