Even if the granular material is dropped separately by using such a vibrating cage, the resin material may fall as a set, or conversely, none of the particles may fall. In some cases, it was not possible to separate the grains. An object of the present invention is to dispense accurately divided granular resin material, thereby or accurately meter / count resin material, the feed amount / number per during unit time by or accurate is there.

  In order to achieve the above object, in the present invention, the reservoir portion and the delivery portion are arranged on the opposite sides of the concave portion moving body, and the resin material enters from the inlet end on one side of the concave portion facing the reservoir portion. The resin material was sent out from the other end of the recess facing the delivery part, and the upper end of the recess was made smaller than the end. Further, in the present invention, the resin material in the reservoir is agitated in the direction opposite to the moving direction of the concave moving body from the vicinity of the end of the moving direction of the concave moving body in the reservoir to the vicinity of the starting end.

  As a result, only the amount / number of the resin material to be measured / counted accurately enters the recess and the resin material does not enter excessively, and the resin material collides with the entrance end of the recess and is difficult to enter the recess. It will never be. Moreover, since it stirs, the resin material does not harden inside the reservoir, and the resin material does not easily enter the recess. As a result, the distribution amount / distribution number of the resin material per unit time becomes accurate (FIGS. 6 and 7). It is possible to feed one grain at a time without excess or deficiency.

(1) Field / use of resin material distribution device / resin product production device The resin material distribution device / resin product production device of the present invention is incorporated in a production apparatus / equipment for resin molded products. Resin molded products are small and light, but they can be medium / medium weight, large / weight, and they are weighed and counted one by one. The resin material P distributed by the present apparatus / method may be a natural material / N material or a master badge / MB.

  The master badge / MB includes a color master badge, which is a pigment for coloring a resin product, a UV cut material, and an antistatic material. In the case of the master badge / MB, this device is installed in the vicinity of another natural material / N material supply device, and the accurately measured / counted master badge / MB is distributed to the natural material / N material. Mixed.

  Furthermore, when mixing master badges of different colors, the mixing amount of the color master badges of the respective colors may be used for light weight and counting. The resin material P is in the form of pellets, but may be in powder form, and the shape of the grains may be cylindrical, prismatic, spherical, elliptical, cubic, rectangular, polyhedral, etc., approximately the same size or approximately the same weight However, different sizes or weights may be mixed.

  The color of such a colored resin product is not only a single color but also a pattern composed of a plurality of colors such as a wood grain pattern and a marble pattern. Such a pattern is different in melting point / melting temperature of each color master badge to be mixed.

  The weight of the resin material P is about 0.001 g to 1 g, 0.005 g to 0.5 g, 0.01 g to 0.1 g, but other heavy weights may be used.

(2) Resin material distributor (first embodiment)
FIGS. 1 to 3 show the structure of a first embodiment of a resin product production apparatus or resin material distribution apparatus that realizes a resin product production method or resin material distribution method. The case 1 is composed of two or more units, and a mechanism and equipment described later are built in between the units. A motor 2 is built in the center of the case 1 slightly below. The center of the disc-shaped concave portion moving rotor 3 is fixed to the rotating shaft of the motor 2.

  A plurality of recesses 4 are formed at equal intervals / equal angles on the periphery of the circular recess moving rotor 3. The concave portions 4 are connected through like a groove from one side of the disc-shaped concave portion moving rotor 3 to the other surface, and the peripheral edge of the concave portion moving rotor 3 has a gear shape. The size of the entrance end 5 on one side of the recess 4 is the same as the size of the exit end 6 on the other side.

  The recesses 4 are slightly larger than the size of one grain of the granular resin material P, smaller than the size of two grains, and are not large enough to contain two grains. If two grains are put into the recesses 4..., The recesses 4 are slightly larger than the size of the two grains of the granular resin material P, smaller than the size of the three grains, and are not large enough to contain the three grains. Similarly, if the number of grains to be placed in the recesses 4 is N, the recesses 4 are slightly larger than the size of the N grains of the granular resin material P, smaller than the size of the N + 1 grains, and no N + 1 grains are contained. It becomes size.

  Further, when the size of one grain resin material P is large and the weight is increased, the size of the recesses 4 is increased. When the size of one grain resin material P is small and the weight is decreased, the recesses 4. The sizes of the entrance end 5 and the exit end 6 are also reduced, and the sizes of the recesses 4..., The entrance end 5 and the exit end 6 are changed depending on the size / weight of one grain of the granular resin material P.

  A rectangular parallelepiped cavity reservoir 7 is formed along the upper edge of the concave moving rotor 3. In this reservoir portion 7, a large number of granular resin materials P having substantially the same size and the same weight are supplied and stored therein. The concave portion moving rotor 3 sequentially moves in the reservoir portion 7, and the resin material P is put into the concave portions 4... While passing through the reservoir portion 7.

  A cylindrical hollow supply cavity 9 extending obliquely upward is formed in the vicinity of the start end of the rotation direction (movement direction) of the concave portion moving rotor 3 of the reservoir portion 7. From the supply cave 9, the resin material P is sent by natural fall by its own weight. The supply cave 9 is inclined with respect to the gravity direction / the direction of the weight of the resin material P, the accumulated pressure of the resin material P is relaxed, and the falling pressure of the resin material P hits the edge of the recessed portion moving rotor 3. The resin material P is not hardened by the pressure of its own weight, and it becomes easy to enter the recesses 4.

  The central direction of the supply cavity 9 is directed from the top of the recessed portion moving rotor 3 to a position shifted in the direction opposite to the rotational direction (moving direction) of the recessed portion moving rotor 3. Therefore, it can be said that the recessed portion moving rotor 3 moves from a low position to a high position in the reservoir 7 and the resin material P is supplied toward a low position in the reservoir 7.

  Therefore, the resin material P is less likely to solidify along the rotation direction (movement direction) of the concave portion moving rotor 3, and the concave portions 4 are easily entered. The resin material P is agitated from the bottom of the reservoir 7 and is agitated by the rotation (movement) of the recess moving rotor 3, so that the resin material P does not harden and easily enters the recesses 4 ....

  The vicinity of the end of the recess moving rotor 3 in the reservoir 7 in the rotational direction (movement direction) is slightly lower than the top of the recess moving rotor 3, but the end of the recess moving rotor 3 in the rotation direction (movement direction). The vicinity is higher than the vicinity of the start end, and it can be said that the concave portions 4 of the concave portion moving rotor 3 are rotated / moved from a low position in the reservoir portion 7 to a high position as a whole.

  The vicinity of the end in the rotational direction (moving direction) of the concave portion moving rotor 3 of the reservoir portion 7 is curved up and down. An air discharge hole 8 is formed at the back of the curved surface, and the air discharge hole 8 is connected to the outer surface of the case 1. Air that has been pressurized by a compressor or a blower is sent into the air discharge hole 8, and air is sent and blown to the resin material P in the reservoir 7.

  Thereby, the resin material P dragged along the rotation direction (movement direction) of the moving rotor 3 is blown away, the resin material P is stirred, and the resin material P is rotated along the rotation direction (movement direction) of the concave movement rotor 3. The material P is hard to be hardened and collected, and the resin material P easily enters the recesses 4.

  The air discharge hole 8 is provided in the vicinity of the raised center of the reservoir 7, the air discharge hole 8 is horizontally oriented, and the reservoir 7 is also substantially horizontal. Then, the inner upper half in the reservoir portion 7 becomes a cavity without the resin material P. The resin material P in the reservoir 7 is easily agitated, the resin material P in the reservoir 7 is hard to be hardened and collected, and the resin material P easily enters the recesses 4.

  As described above, the resin material P in the reservoir 7 moves from the vicinity of the end in the rotational direction / movement direction of the recess moving rotor 3 in the reservoir 7 toward the vicinity of the start by the air ejected from the air discharge hole 8. Stirring is performed in the direction opposite to the rotational direction / movement direction of the rotor 3.

  The side surface of the reservoir 7 near the air discharge hole 8 is curved, and the boundary between the reservoir 7 below the air discharge hole 8 and the inner surface of the case 1 that encloses the recessed portion moving rotor 3 is sharp. Therefore, only the resin material P in the recesses 4... Can be cut out or separated from the large number of resin materials P accumulated in the reservoir 7.

  As a result, the halfway resin material P which is half-filled in the recesses 4 is eliminated, and the entire resin material P of only one grain is reliably stored in the recesses 4. Therefore, the resin material P is stored exactly one by one in the recesses 4 of the recessed portion moving rotor 3 without excess or deficiency, and is accurately delivered one by one from the delivery unit 10 and distributed.

  Immediately below the concave portion moving rotor 3 is formed a delivery portion 10 extending vertically above and below a quadrangular columnar cavity. The thickness of the feeding portion 10 is substantially the same as the thickness of the concave portion moving rotor 3, and the width of the feeding portion 10 is slightly larger than the interval between the concave portions 4. The concave portion 4 containing the resin material P of the concave portion moving rotor 3 passes through the reservoir portion 7, the concave portion moving rotor 3 rotates and moves, and the position and orientation of the concave portion 4 changes, and the resin in the concave portion 4. The material P is fed into the delivery unit 10 by its own weight.

  The portions other than the delivery portion 10, the reservoir portion 7, and the supply cave 9 have a slight gap as the inner surface of the case 1 approaches the outer surface of the recessed portion moving rotor 3. 9 is isolated. Therefore, the resin material P that has not entered the recesses 4 of the recess moving rotor 3 is not sent from the reservoir portion 7 and the supply cavity 9 to the delivery portion 10. Therefore, according to the rotational speed of the recessed portion moving rotor 3, the resin material P is delivered from the delivery unit 10 exactly one by one and distributed.

  Further, as described above, the resin material P in the reservoir portion 7 is hard to solidify and collect, and the resin material P easily enters the recesses 4..., So that the resin material P is exactly one particle at a time in the recesses 4 of the recess moving rotor 3. It is stored in the inside without excess and deficiency, and is delivered from the delivery unit 10 accurately one by one and distributed.

  The number / rotational speed of the concave portions 4 of the concave portion moving rotor 3 varies depending on the amount / number of the resin material P to be delivered per unit time. The time spent for distributing one resin material P varies depending on the amount / number of resin materials P to be delivered per unit time.

(3) Resin material distributor (second embodiment)
4 to 5 show the structure of a second embodiment of the resin material distributor. The cylindrical reservoir 27 is inclined with respect to 45 degrees and installed with respect to the case 21. The upper portion of the reservoir 27 is isolated by a partition wall 31, and a cylindrical motor chamber 32 is formed on the partition wall 31. The thickness of the outer wall of the motor chamber 32 is thicker than the thickness of the outer wall of the reservoir 27.

  A motor 22 is fixed in the motor chamber 32. The rotation shaft 33 of the motor 22 is along the center line of the cylindrical reservoir 27 and the motor chamber 32. A disc-shaped concave portion moving rotor 23 is located inside the bottom surface of the reservoir portion 27, and the center of the concave portion moving rotor 23 is fixed to the rotating shaft 33 and is rotatable.

  A plurality of recesses 24 are formed at equal intervals on the periphery of the recess moving rotor 23. The recesses 24 are connected through like a groove from one side of the disc-shaped recess moving rotor 23 to the other side, and the periphery of the recess moving rotor 23 is gear-shaped. The size of the entrance end 25 on one side of the recesses 24 is smaller than the size of the exit end 26 on the other side.

  The entrance ends 25 and the exit ends 26 of the recesses 4 are slightly larger than the size of one grain of the granular resin material P, smaller than the size of two grains, and are not large enough to contain two grains. If two grains are put into the entrance ends 25 and the exit ends 26 of the recesses 4, the entrance ends 25 and the exit ends 26 of the recesses 4 are slightly larger than the size of the two grains of the granular resin material P, The size is smaller than the size of the three grains, and the three grains do not enter.

  Similarly, if the number of grains desired to be placed in the entrance ends 25 and the exit ends 26 of the recesses 4 is N, the entrance ends 25 and the exit ends 26 of the recesses 4 are formed of the granular resin material P. The size is slightly larger than the size of N grains, smaller than the size of N + 1 grains, and does not contain N + 1 grains.

  Further, when the size of one grain of the granular resin material P is large and the weight is increased, the sizes of the entrance ends 25 and the exit ends 26 of the recesses 24 are also increased, and the size of one grain of the granular resin material P is increased. If the size is small and the weight is light, the size of the recess 24..., The entrance end 25 and the exit end 26 is reduced, and the recess 24... The size of 26 also changes.

  The circular bottom plate 34 of the cylindrical reservoir 27 is also inclined obliquely by 45 degrees, and a circular hole is partially opened on the upper side of the bottom plate 34. A mounting plate 35 is joined under the bottom plate 34, and a circular hole is formed in the mounting plate 35. The circular hole of the mounting plate 35 and the circular hole of the bottom plate 34 have the same shape and size. It is fixed in the same position without being displaced. The upper end of the cylindrical delivery part 30 is joined to the circular hole of the mounting plate 35.

  A circular hole is formed in the upper side above the side surface of the reservoir 27, and a curved cylindrical supply sinus 29 is joined to the circular hole. From the supply cave 29, the resin material P is sent by natural fall by its own weight. The supply cave 9 is curved so as to be separated from the bottom plate 34 of the reservoir 27, so that the falling pressure of the resin material P and the accumulated pressure of the resin material P are not applied to the recessed portion moving rotor 23. Is not hardened by the pressure of its own weight and can easily enter the recesses 4 of the recess moving rotor 23.

  The supplied resin material P is in the form of a large number of particles having substantially the same size and the same weight, and is stored in the storage portion 27. The recesses 24 of the recess moving rotor 23 sequentially move in the reservoir 27, and the resin material P is put into the recesses 4 while passing through the resin material P stored in the reservoir 27. .

  The reservoir portion 27 and the delivery portion 30 are disposed on the opposite sides with respect to the concave portion moving rotor 23. The concave portion 24 of the concave portion moving rotor 23 is inserted into the concave portion 24 facing the reservoir portion 27 from one input end 25 of the concave portion 24. The resin material P is sent out from the end 26 to the delivery part 30.

  The entrance ends 25 of the recesses 24 are smaller than the exit ends 26, and the recesses 24, that is, the inner surface, that is, the inner bottom surface and the inner surface are inclined from the entrance ends 25 to the exit ends 26. Therefore, the inclined surface approaches a vertical direction when the recesses 24 are positioned in the delivery part 30, so that the resin material P in the recesses 24 is easily sent out by its own weight.

  Further, when the recesses 24 are positioned below the reservoir 27, the inner bottom surface of the recesses 24 approaches the horizontal, and the angle between the upper side surface of the recess moving rotor 23 and the inner bottom surface of the recesses 24 is sharp. The inner bottom surface of 24... And the upper surface of the recess moving rotor 23 can cut or separate only the resin material P in the recess 24.

  As a result, the halfway half of the resin material P that is half-entered in the recesses 24 is eliminated, and the entire resin material P of only one grain is reliably stored in the recesses 24. Therefore, the resin material P is stored exactly one by one in the recesses 24 of the concave portion moving rotor 23 without being excessive and insufficient, and is accurately delivered one by one from the delivery unit 30 and distributed.

  Further, the reservoir 27 is located below the delivery portion 30, and the resin material P is put into the recesses 24 below the recess moving rotor 23, and the resin material P is above the recess moving rotor 23 from the recess 24. Is issued. As a result, when the recesses 24 are positioned in the delivery part 30, the resin material P other than the resin material P in the recesses 24 does not hit the entry ends 25 of the recesses 24, so that the delivery parts 30 are passed from the recesses 24. When the resin material P is sent out, the resin material P is not mistakenly passed through the recesses 24...

  The opposite side of the recessed portion moving rotor 23 to the feeding portion 30 is opened as an upper portion of the reservoir portion 27, and the opposite side of the recessed portion moving rotor 23 to the reservoir portion 27 is closed by the bottom plate 34 and the mounting plate 35. All the exit ends 26 except for 30 are closed. Therefore, the resin material P that has entered the recesses 24 at the lower side of the reservoir 27 is not sent out from the exit ends 26 of the recesses 24 at locations other than the delivery part 30.

  An air discharge nozzle 28 is provided on the upper side below the side surface of the reservoir 27, and air pressurized by a compressor or a blower is sent and discharged. The air discharge nozzles 28 are directed to the entrance ends 25 of the recesses 24 of the recess moving rotor 23. Therefore, when the recesses 24 are located in the delivery part 30, air is sent from the entry end 25 ... side and blown against the resin material P that has entered the recesses 24, so that the delivery part 30 is surely received. Sent out.

  The clearance between the peripheral edge of the recessed portion moving rotor 23 and the inner surface of the cylindrical reservoir 27 is very small, and the delivery portion 30, the reservoir 27, and the supply cavity 29 are separated from each other by a bottom plate 34, a mounting plate 35, and the like. Has been. Therefore, the resin material P that has not entered the recesses 24 of the recess moving rotor 23 is not sent from the reservoir portion 27 and the supply cavity 29 to the delivery portion 30. Therefore, according to the rotational speed of the recessed portion moving rotor 23, the resin material P is accurately delivered from the delivery unit 30 one by one and distributed.

  In the lower half of the upper half of the reservoir 27, a shielding chamber 36 is provided to prevent the resin material P from entering. The shielding chamber 36 is surrounded by a rectangular plate that passes through the center of the reservoir 27 and two rectangular plates that are arranged obliquely along the rotation axis of the motor 22. The rotating shaft of the motor 22 passes between the two rectangular plates.

  As a result, the opposite side of the recess moving rotor 23 to the delivery portion 30 is closed, and when the recesses 24 are positioned in the delivery portion 30, the resin material P in the recesses 24 is placed at the entry ends 25 of the recesses 24. When the resin material P other than the resin material P does not hit and the resin material P is sent out from the recesses 24 to the delivery part 30, the resin material P erroneously passes through the recesses 24 following the sent out resin material P and is sent out excessively. It will not be.

  The reservoir 27 in FIG. 4 is cylindrical and has a circular cross section. However, the lower half of this cylinder may be the reservoir 27. In this case, the resin material P may protrude from the reservoir 27 or may not protrude. The upper half of the reservoir 27 may be omitted, may be filled with some member, or may be thinner.

  As a result, the opposite side of the recessed portion moving rotor 23 from the delivery portion 30 is closed, and the opposite side of the recessed portion moving rotor 23 from the reservoir portion 27 is also closed. On the contrary, the delivery part 30 may be thick and may have the same thickness as the reservoir 27, or may be thicker than the reservoir 27.

  As a result, the reservoir 27 is located below the delivery portion 30, the resin material P is put into the recesses 24 below the recess moving rotor 23, and the resin material P comes out of the recess above the recess moving rotor 23. Will be. Even in this case, the resin material P other than the resin material P in the recesses 24 does not hit the entry ends 25 of the recesses 24.

  Other configurations, operations, and effects of the second embodiment are the same as those of the first embodiment, and these descriptions are also described in the present embodiment. It is also described in the first embodiment. Other embodiments are referred to as not being described in the second embodiment, and embodiments other than the first embodiment are referred to as not being described in the first embodiment.

In this experiment, the resin material P is a color masterbatch, 0.02 g per grain, and one grain is charged at a time, 0.1 g or 5 grains are charged per resin product, that is, one molding shot, and the charging speed is 5 / Min = 0.1 g / min.

  A conventional screw-type resin material supply device was used as a comparison object. In FIG. 6, the conventional screw type is indicated by a broken line of Δ, and the resin material distributor / resin product production apparatus of the present embodiment / the present invention is indicated by a broken line of ◇. In this example / present invention, the actual dispensing amount / feeding amount was weighed / counted 100 times at a speed of 0.27 g / 10 seconds for the conventional screw type and 0.43 g / 10 seconds for the conventional screw type.

  In the experiment shown in FIG. 6, the distribution amount / supply amount of the resin material in the conventional screw type of the broken line marked with △ varies considerably, but this example of the broken line marked with ◇ / distribution amount of the resin material of the present invention / The variation in supply is considerably reduced. Even when the conventional screw type is set to 0.25 g / 10 seconds, the above variation is only slightly reduced. From this, it can be seen that the distribution amount / supply amount of the present embodiment / present invention is quite accurate and has little variation.

  In the experiment of FIG. 7, the supply rate / distribution rate of the resin material distribution device / resin product production device of the present example / invention was set to 0.35 g / min (◇ broken line), 2.25 g / min (□ mark). The amount of distribution / feed per minute was weighed / counted 30 times, changing to three stages of 4.85 g / min (Δ marked line).

  Even in the experiment of FIG. 7, even when the distribution rate / supply rate is changed, the distribution amount / supply amount of the resin material of this example / present invention is accurate and the variation is considerably reduced. As a result, the distribution amount / number of distribution of the resin material per unit time becomes accurate, and it can be delivered accurately one by one without excess or deficiency.

(5) Other Embodiments The present invention is not limited to the above embodiments, and various modifications can be made. For example, some or all of the supply cavities 9 and 29, the reservoirs 7 and 27, the delivery parts 10 and 30, the case 1, the recessed portion moving rotors 3 and 23, the partition wall 31, the rotating shaft 33, the bottom plate 34, and the mounting plate 35 It can be a name. As a result, the movement of the resin material P is well understood, and inspection, failure discovery, and repair are facilitated.

  The resin material P may be a mixture of granular materials having different sizes in addition to many of the same size. In this case, among the resin materials P having different sizes, only a specific resin material P that matches the size of the recesses 24 of the recess moving rotors 3 and 23 can be selected and distributed from the delivery units 10 and 30. The particle size of the resin material P is arbitrary, and may be large, small, or powder.

  The supply cave 9 is obliquely close to the vertical, and the directions of the supply cave 29 and the reservoir 27 are 45 degrees, but may be vertical, may be horizontal, or may be nearly vertical. The reservoir 7 may be on the recess moving rotor 3, on the side, or between these positions, and the reservoir 27 may be below, on the side of the recess moving rotor 23, or between these positions. Even in this case, the accumulated pressure of the resin material P is relaxed. When the direction of the supply cave 9 is horizontal or nearly horizontal, the resin material P may be fed by blowing air into the supply cave 9 along the flow of the resin material P.

  The supply amount of the resin material P per unit time is determined so that there is a gap without the resin material P in the reservoirs 7 and 27. Further, a gap is formed in the resin material P in the reservoirs 7 and 27 also by the air ejected from the air discharge hole 8. Such an air discharge hole 8 may also be provided in the reservoir 27 of FIG. As a result, the resin material P is well agitated without being solidified by the accumulated pressure, and the resin material P smoothly enters the concave portions 4, 24, of the concave portion moving rotors 3, 23.

  Although one grain of the resin material P is contained in the concave parts 4. Correspondingly, or when the size of one resin material P is changed, or when the amount / number of the resin material P delivered per unit time is changed, the concave portions 4 of the concave portion moving rotors 3, 23,. The size / width / depth / number is changed.

  In this case, the concave portion moving rotors 3 and 23 are exchanged in accordance with the size / width / depth / number of the desired concave portions 4. Further, when changing the feed amount / number of grains per unit time, the rotational speed of the recessed portion moving rotors 3 and 23 is changed, or the recessed portion moving rotors 3 and 23 are replaced with the recessed portion moving rotors 3 and 23 having a small number of recessed portions 4. The

  In addition to the “U” shape, the cross-sectional shape of the concave portions 4, 24 of the concave portion moving rotors 3, 23 is “V” shape, “C” shape, rectangular shape, circular shape, elliptical shape, trapezoidal shape, polygonal shape, star shape, A curved shape or a stepped shape may be used. The thicknesses of the recess moving rotors 3 and 23 and the depth / width dimensions of the recesses 4... 24 are not different and are not more than twice as large. There is no difference and the difference is twice or less.

  Further, the thicknesses of the concave portion moving rotors 3 and 23 and the depth / width dimensions of the concave portions 4... 24 are slightly larger than the largest dimension of the length and width width of the resin material P. As a result, the resin material P is reliably stored one by one in the recesses 4... 24 of the recess moving rotors 3, 23, and two or more resin materials P are not stored in excess.

  The recess moving rotors 3, 23 may be belts having recesses 4, 24,... Formed at regular intervals / predetermined intervals. The recesses 4, 24, 24 containing the resin material P pass through the reservoirs 7, 27. As long as the position and orientation of the recesses 4... 24 are changed and the resin material P in the recesses 4. In this case, the belt is stretched around a plurality of pulleys, and the belt circulates between the reservoir portions 7 and 27 and the delivery portions 10 and 30.

  In addition to the case 1, the bottom plate 34, and the mounting plate 35, the reservoirs 7 and 27 and the supply cavities 9 and 29 can be separated from the delivery unit 30 as long as they can be separated. The supply cavities 9 and 29 may be a hopper tank or the like in which the resin material P is stored in addition to the cylindrical shape. The reservoirs 7 and 27 may also be the lower part of a hopper tank in which the resin material P is stored.

  Reservoir parts 7 and 27 and delivery parts 10 and 30 are arranged on the opposite side of the upper and lower sides in FIG. 1 with respect to recess moving rotors 3 and 23, and on the opposite side of one side and the other side in FIG. Has been placed. However, they may be arranged on the same side.

Thus, the resin material P other than the resin material P in the recesses 4 does not hit the input ends 5 of the recesses 4.

  In the first embodiment of FIG. 1, when the recessed end moving rotor 3 has an inlet end 5 smaller than the outlet end 6, and the recessed portion 4 is positioned in the delivery portion 10, the resin material P is in the delivery portion 10. In addition, air may be applied from the entry end 5 side of the recess 4. In this case, air may be applied from the end 6. In this case, the resin material P is discharged and sent out from between the input end 5... And the output end 6. Moreover, the delivery part 10 may be extended to the outgoing end 6 ... side, and may be extended on both sides of the outgoing end 6 ... and the incoming end 5 .... In this case, air is applied from the input end 5 side.

  In the second embodiment of FIG. 4, the recessed portion moving rotor 23 circulates between a high position and a low position, but in the half of the reservoir portion 27, the recessed portion moving rotor 23 moves from a low position to a high position. It can be said. In this case, only the half of the cylindrical reservoir 27 may be the reservoir 27, and the other half may be closed / filled, or the cylindrical reservoir 27 may be semicylindrical.

  In the second embodiment of FIG. 4, the shielding chamber 36 may be omitted. In this case, the supply amount per unit time of the resin material P fed into the reservoir portion 27 is adjusted so that the resin material P does not reach the upper side of the recessed portion moving rotor 23, that is, the opposite side of the delivery portion 30.
