Description

  The present invention relates to a sheet-like pulp supply device used when producing an amino resin molding material.

  Amino resin molding materials such as urea resin molding materials and melamine resin molding materials are widely used for producing various molded products such as tableware, wiring devices, and electrical insulation materials. Such an amino resin molding material is produced by mixing an amino resin and a material obtained by pulverizing the sheet-like pulp 2. For example, the amino resin molding material is produced by a production facility as shown in FIG. That is, the amino resin is prepared as resin syrup (initial condensate) by first charging the raw material aldehydes and amino compound into the condensation kettle 27 and then passing them through a plurality of reaction tanks 29 by the liquid feed pump 28. The resin syrup is then fed to the crushing kneader 15. On the other hand, the sheet-like pulp 2 is supplied to the crushing kneader 15 by the sheet-like pulp supply device 1. The pulverized kneader 15 crushes the sheet pulp 2 and impregnates the pulverized pulp with resin syrup. Thereafter, the impregnated material is heated by a heating kneader 30 to remove condensed water, and is further kneaded by a mixer 31 and then dried by a rotary dryer 32. The dried product is cooled by the cooling feeder 33, temporarily stored as an amino resin molding material in the storage silo 34, and transferred to the next step such as a molding step as necessary.

Here, in producing the amino resin molding material, it is necessary to keep the blending ratio of the amino resin and the pulverized pulp constant and to stabilize the quality. As the sheet pulp supply device 1 used in such a production facility, a device capable of supplying a certain amount of the sheet pulp 2 to the crushing kneader 15 in a certain time is required. As such a sheet-shaped pulp supply apparatus 1, although the technical field utilized is not necessarily the same, the paper feeder etc. which were described in patent document 1 can be used, for example.

The small pulp 2b is arranged at substantially the center in the width direction of the large pulp 2a, and one side of the four sides is aligned, and the aligned one side is stacked and mounted on the mounting table 14 toward the supply destination side. When the large and small pulps 2a and 2b are stacked and mounted in this way, as shown in FIG. 2A, the large pulp 2a protrudes from the small pulp 2b on the side opposite to the supply destination side, and the protruding portion 16 is formed. In addition, below, the supply destination side of the sheet-like pulp 2 is made into the front, and the other side is demonstrated as back.

  In the present invention, as will be described later, the sheet-like pulp supply device 1 includes a separating means 5, a conveying means 8, air blowing means 9 and 10, a size discrimination sensor 11, a dispersion promoting means 13, and a pulp counting means 35. And a storage portion 36. Further, as shown in FIG. 7, the separating means 5, the conveying means 8, the air blowing means 9 and 10, the size discrimination sensor 11, the dispersion promoting means 13, the pulp counting means 35, and the storage unit 36 are Are electrically connected to a control unit 17 formed by a CPU or the like, and the operation of each unit is controlled by the control unit 17.

  As shown in FIG. 1, the separating means 5 is formed by providing the first suction pad 3 at the tip of the first cylinder 4. The first suction pad 3 is connected to a vacuum pump (not shown), and can freely adsorb the sheet-like pulp 2 and release the adsorption. The first cylinder 4 is formed to be movable in the vertical direction. And the ballast means 5 formed in this way is fixed and installed above the sheet-like pulp 2 stacked and mounted. Specifically, as shown in FIG. 2A, two brush means 5 are fixedly installed above the two rear corners among the four corners of the stacked small pulp 2b. In addition, the number of the ballast means 5 is not limited to two.

  As shown in FIG. 1, the conveying means 8 is formed by providing the second suction pad 6 at the tip of the second cylinder 7. Similarly to the first suction pad 3, the second suction pad 6 is also connected to a vacuum pump (not shown) so that the sheet-like pulp 2 can be freely sucked or released. It has become. Similarly to the first cylinder 4, the second cylinder 7 is also formed to be movable in the vertical direction. And the conveyance means 8 formed in this way is installed so that the movement in the supply direction (front-back direction) of the sheet-like pulp 2 is carried out above the sheet-like pulp 2 laminated and mounted. Specifically, as shown in FIG. 2A, two conveying means 8 are installed above the two front corners of the four corners of the stacked and placed small pulp 2b, and the small pulp 2b is further disposed. Two conveying means 8 are installed between the rear separating means 5 and the front conveying means 8 along the side. These four conveying means 8 can be integrally moved in the supply direction of the sheet pulp 2. Note that the number of the conveying means 8 is not limited to four.

  As shown in FIG. 1, a feeding roller 18 including a pair of rollers 18 a and 18 b is installed above the mounting table 14. One roller 18a constituting the feeding roller 18 is movable up and down, and the other roller 18b is fixed at a certain height. Further, as shown in FIG. 5, one end of a rod-shaped part to be measured 42 is attached to one roller 18a. The portion to be measured 42 is attached so as not to rotate with the roller 18a but to maintain a horizontal state. A displacement sensor 37 is installed above the other end of the measured part 42. The displacement sensor 37 is formed of a reflective photoelectric sensor, and the light emitted from the light projecting unit 40 is reflected by the measured unit 42 and detected by the light receiving unit 41, whereby the measured unit 42. The amount of vertical displacement can be measured. Since the amount of displacement corresponds to the distance between the pair of rollers 18a, 18b, there are a plurality of sheet-like pulps 2 between the pair of rollers 18a, 18b according to the measurement result obtained by the displacement sensor 37. Thus, it can be determined whether the state is a multiple feed state, or the sheet-like pulp 2 is not present between the pair of rollers 18a, 18b and is in an idle feed state. The displacement sensor is also electrically connected to the control unit 17 as shown in FIG. 1 and 3, the displacement sensor 37 is not shown.

  The air blowing means 9 and 10 are formed by an air nozzle 19 connected to an air pump (not shown). As shown in FIG. 1, a switching valve (SV) 20 provided in front of the air nozzle 19 is free. The air can be blown on or stopped. And the air spraying means 9 and 10 formed in this way are installed in the back of the sheet-like pulp 2 laminated | stacked and mounted, as shown in FIG. Has been. Hereinafter, the former air blowing means 9 will be described as the first air blowing means 9 and the latter air blowing means 10 will be described as the second air blowing means 10. In addition, when the air spraying means 9 and 10 formed so that a vertical movement is possible, the number to install can be made into one, but the number of the air spraying means 9 and 10 is limited to one or two. is not.

  The size discrimination sensor 11 is formed so as to detect the presence of the sheet-like pulp 2 when it enters the detection region. For example, the size discrimination sensor 11 can be formed by a reflective photoelectric sensor or the like. And the size discrimination | determination sensor 11 formed in this way is not the upper part of the small pulp 2b but the upper part of the back two corners among the four corners of the large pulp 2a stacked and mounted, as shown in FIG. As shown in FIG. 1, the detection area is set downward. However, in a state where the sheet-like pulp 2 is not lifted, the size-determining sensor 11 does not detect the presence of the stacked and placed sheet-like pulp 2, so that the stacked and placed sheet-like pulp 2 is size-determined. The size discrimination sensor 11 is installed at a height that does not enter the detection area of the sensor 11. That is, the distance from the uppermost sheet-like pulp 2 to the size discrimination sensor 11 is longer than the detection region (detection distance) of the size discrimination sensor 11. Therefore, in the state where the sheet-like pulp 2 is not lifted, the size discrimination sensor 11 does not detect anything, but as shown in FIG. 3B described later, when the brush means 5 lifts the large pulp 2a, the size discrimination sensor Since the protruding portion 16 of the large pulp 2a enters the 11 detection region, it is possible to determine that the uppermost sheet-like pulp 2 is the large pulp 2a. On the other hand, as shown in FIG. 1 (b), when the brush means 5 lifts the small pulp 2 b, the size discrimination sensor 11 is not installed above the small pulp 2 b, and the small pulp 2 b is located in the detection area of the size discrimination sensor 11. Since it does not enter, it can be determined that the uppermost sheet-like pulp 2 is the small pulp 2b. In this way, the size discrimination sensor 11 can discriminate the size of the sheet pulp 2. The number of size determination sensors 11 is not limited to two.

  The spread promoting means 13 is formed by a coil spring 12, and as shown in FIG. 6, with the pitch direction being the vertical direction, the sheet pulp 2 It is installed to be movable in a direction (width direction) perpendicular to the supply direction (front-rear direction). 1 and 3, the separation promoting means 13 is not shown. Here, as the coil spring 12, those having the same diameter in the vertical direction as shown in FIG. 6 can be used, and those having a diameter increasing from bottom to top can be used. Further, the separation promoting means 13 can be formed to be movable in the width direction of the sheet-like pulp 2 by providing the coil spring 12 in the spring holding portion 23 of the tip portion 22 of the cylinder 21. Further, as shown in FIG. 6, the spread promoting means 13 is installed at a position where the coil spring 12 is caught on the side edge of the sheet-like pulp 2 when the uppermost sheet-like pulp 2 is lifted. ing. In the one shown in FIG. 2, two separation promoting means 13 are installed above each of two sides along the front-rear direction of the sheet-like pulp 2. Among these, the separation promoting means 13 located at the back of each side are opposed to each other, and the separation promoting means 13 located at the front of each side are opposed to each other. In addition, in the thing shown in FIG. 2, although the number of the balance promotion means 13 is four, it is not limited to this.

  The pulp counting means 35 counts the number of the sheet-like pulp 2 passing through the feeding roller 18 and is formed of a reflective photoelectric sensor. The pulp counting means 35 formed in this way is installed above the front of the feeding roller 18 as shown in FIG. Then, the light emitted from the light projecting unit 38 of the pulp counting means 35 is reflected by the sheet pulp 2 and returned to the light receiving unit 39, thereby detecting the presence of the sheet pulp 2 passing through the feeding roller 18. And the number of sheets can be counted. In FIG. 1 and FIG. 3, the pulp counting means 35 is not shown.

  The storage unit 36 can be formed of various memories, storage media, and the like. The number of sheets of sheet-like pulp 2 of each size obtained by the pulp counting means 35 and the size discrimination sensor 11 within a certain time is used as data. It can be memorized. Specifically, the number of small pulps 2b and large pulps 2a that have passed through the feeding roller 18 within a certain time can be stored in the storage unit. Further, the contents stored in the storage unit 36 can be confirmed by an operator as necessary using an output device (not shown) or the like.

  Next, a series of operations of the sheet-like pulp supply device 1 formed as described above will be described.

  First, as shown in FIG. 1A, the case where the uppermost sheet-like pulp 2 is a small pulp 2b will be described. First, before the uppermost sheet-like pulp 2 is adsorbed by the first adsorption pad 3 of the ballasting means 5, the first air blowing means 9 blows air onto the side surface of the laminated sheet-like pulp 2. Thereby, before using the separating means 5, the laminated pulp 2 can be separated to some extent.

  Next, as shown in FIG. 1 (b), the uppermost sheet-like pulp 2 is adsorbed and lifted by the first adsorption pad 3 of the ballast means 5. Since the sheet-like pulp 2 lifted at this time is the small pulp 2b, it is determined that the uppermost sheet-like pulp 2 is the small pulp 2b without entering the detection region of the size discrimination sensor 11, and this detection result is controlled. Transmitted to the unit 17. Subsequently, the ballasting means 5 swings up and down a plurality of times in a state where the uppermost sheet-like pulp 2 is adsorbed and lifted by the first adsorption pad 3. The extra sheet-like pulp 2 that is stuck to the uppermost sheet-like pulp 2 can be dropped by the brushing operation of the brush means 5. Further, as shown in FIG. 1 (b), when performing the above-described scrubbing operation, the second air spraying means 10 blows air onto the side surface of the sheet-like pulp 2 that is undergoing the scoring operation. And the fall of the excess sheet-like pulp 2 can be accelerated | stimulated during use of the brush means 5. After the end of the shrinking operation, as shown in FIG. 1C, the suction by the first suction pad 3 is released, and the sheet-like pulp 2 once lifted is dropped. Due to this drop impact, it becomes easier to separate the uppermost layer from the laminated sheet-like pulp 2.

  By the way, the control part 17 which received the detection result from the size discrimination | determination sensor 11 moves the dispersion | variation promotion means 13 to the width direction based on this detection result. Specifically, since the uppermost sheet-like pulp 2 is the small pulp 2b, when the small pulp 2b is lifted, the position is such that the coil spring 12 is hooked on the side edge and does not hinder the lifting. As shown in FIG. 2B, the brush promoting means 13 is moved along the width direction of the small pulp 2b so as to come to such a position.

  And as shown in FIG.1 (d), although it adsorbs and lifts the uppermost sheet-like pulp 2 with the 2nd adsorption pad 6 of the conveyance means 8, as shown in FIG. The coil spring 12 of the brush promoting means 13 is continuously hooked to the side edge of the sheet-like pulp 2 being lifted, and the excess sheet-like pulp 2 is bounced by the coil spring 12 and falls.

  Subsequently, as shown in FIGS. 1 (e) and 2 (c), the transport means 8 moves forward and the suction by the second suction pad 6 is released, so that the uppermost sheet-like pulp 2 is fed. It is introduced into the roller 18 and supplied to the crushing kneader 15.

  Here, in order to supply the pulverization kneader 15 with a certain amount of sheet-like pulp 2 at a certain time, the number of sheet-like pulps 2 to be conveyed at a certain time is set in the storage unit 36 or the like in advance. However, the occurrence of unforeseen situations such as multiple feeding and idle feeding does not necessarily convey the set number of sheet-like pulps 2. Therefore, in the present invention, when the number of sheet-like pulp 2 actually counted by the pulp counting means 35 is smaller than the preset number of sheets-like pulp 2 conveyed, The control unit 17 controls the transport unit 8 so as to increase the transport speed. Conversely, if the number of sheet-like pulp 2 actually counted by the pulp counting means 35 is larger than the preset number of sheet-like pulp 2 conveyed, the conveyance speed of the sheet-like pulp 2 is decreased. Thus, the control unit 17 controls the conveying means 8. Therefore, even if a state such as multiple feeding or idle feeding occurs, as a result, a certain amount of the sheet-like pulp 2 can be supplied to the crushing kneader 15 in a certain time.

  In particular, when the number of sheet-like pulps 2 actually counted by the pulp counting means 35 is larger than the preset number of sheet-like pulp 2 conveyed, the conveying means 8 is idled. Also good. That is, the conveying means 8 may be made to perform a series of operations without causing the second suction pad 6 to adsorb the sheet-like pulp 2. Thus, the conveyance means 8 is idled to temporarily interrupt the conveyance of the sheet pulp 2, thereby preventing excessive supply of the sheet pulp 2, so that a certain amount of the sheet pulp 2 can be obtained in a certain time. It can be supplied to the crushing kneader 15.

  Similarly, when the number of sheet-like pulp 2 actually counted by the pulp counting means 35 is larger than the preset number of conveyed sheet-like pulp 2, the conveying means 8 is stopped. Also good. Thus, by stopping the conveying means 8 and temporarily interrupting the conveyance of the sheet-like pulp 2, the excessive supply of the sheet-like pulp 2 is prevented, and a certain amount of the sheet-like pulp 2 is dissolved in a certain time. The crushed kneader 15 can be supplied.

  In the multi-feed state, it may be difficult to count the number of sheet-like pulp 2 actually conveyed using only the pulp counting means 35, but if the displacement sensor 37 is also used, The number of conveyed sheet-like pulp 2 can be counted more accurately.

  Next, as shown in FIG. 3A, a case where the uppermost sheet-like pulp 2 is a large pulp 2a will be described. First, before the uppermost sheet-like pulp 2 is adsorbed by the first adsorption pad 3 of the ballasting means 5, the first air blowing means blows air onto the side surface of the laminated pulp 2. Thereby, before using the separating means 5, the laminated pulp 2 can be separated to some extent.

  Next, as shown in FIG. 3 (b), the uppermost sheet-like pulp 2 is adsorbed and lifted by the first adsorption pad 3 of the brush means 5. Since the sheet-like pulp 2 lifted at this time is the large pulp 2a, the protruding portion 16 of the large pulp 2a enters the detection region of the size discrimination sensor 11, and the uppermost sheet-like pulp 2 is the large pulp 2a. The detection result is transmitted to the control unit 17. Subsequently, the ballasting means 5 swings up and down a plurality of times in a state where the uppermost sheet-like pulp 2 is adsorbed and lifted by the first adsorption pad 3. The extra sheet-like pulp 2 that is stuck to the uppermost sheet-like pulp 2 can be dropped by the brushing operation of the brush means 5. Further, as shown in FIG. 3 (b), when performing the above-described crushing operation, the second air blowing means 10 blows air onto the side surface of the sheet-like pulp 2 that is undergoing the crushing operation. And the fall of the excess sheet-like pulp 2 can be accelerated | stimulated. After the end of the shrinking operation, as shown in FIG. 3C, the suction by the first suction pad 3 is released, and the sheet-like pulp 2 once lifted is dropped. Due to this drop impact, it becomes easier to separate the uppermost layer from the laminated sheet-like pulp 2.

  By the way, the control part 17 which received the detection result from the size discrimination | determination sensor 11 moves the dispersion | variation promotion means 13 to the width direction based on this detection result. Specifically, since the uppermost sheet-like pulp 2 is the large pulp 2a, when the large pulp 2a is lifted, the position is such that the coil spring 12 is hooked on the side edge, and does not hinder the lifting. As shown in FIG. 4B, the brush promoting means 13 is moved along the width direction of the large pulp 2a so as to come to such a position.

  And as shown in FIG.3 (d), although it adsorbs and lifts the uppermost sheet-like pulp 2 with the 2nd adsorption pad 6 of the conveyance means 8, as shown in FIG. The coil spring 12 of the brush promoting means 13 is continuously hooked to the side edge of the sheet-like pulp 2 being lifted, and the excess sheet-like pulp 2 is bounced by the coil spring 12 and falls.

  Subsequently, as shown in FIG. 3 (e) and FIG. 4 (c), the transport means 8 moves forward and the suction by the second suction pad 6 is released, so that the uppermost sheet pulp 2 is fed. It is introduced into the roller 18 and supplied to the crushing kneader 15.

  Here, in order to supply the pulverization kneader 15 with a certain amount of sheet-like pulp 2 at a certain time, the number of sheet-like pulps 2 to be conveyed at a certain time is set in the storage unit 36 or the like in advance. However, the occurrence of unforeseen situations such as multiple feeding and idle feeding does not necessarily convey the set number of sheet-like pulps 2. Therefore, in the present invention, when the number of sheet-like pulp 2 actually counted by the pulp counting means 35 is smaller than the preset number of sheets-like pulp 2 conveyed, The control unit 17 controls the transport unit 8 so as to increase the transport speed. Conversely, if the number of sheet-like pulp 2 actually counted by the pulp counting means 35 is larger than the preset number of sheet-like pulp 2 conveyed, the conveyance speed of the sheet-like pulp 2 is decreased. Thus, the control unit 17 controls the conveying means 8. Therefore, even if a state such as multiple feeding or idle feeding occurs, as a result, a certain amount of the sheet-like pulp 2 can be supplied to the crushing kneader 15 in a certain time.

  In particular, when the number of sheet-like pulps 2 actually counted by the pulp counting means 35 is larger than the preset number of sheet-like pulp 2 conveyed, the conveying means 8 is idled. Also good. That is, the conveying means 8 may be made to perform a series of operations without causing the second suction pad 6 to adsorb the sheet-like pulp 2. Thus, the conveyance means 8 is idled to temporarily interrupt the conveyance of the sheet pulp 2, thereby preventing excessive supply of the sheet pulp 2, so that a certain amount of the sheet pulp 2 can be obtained in a certain time. It can be supplied to the crushing kneader 15.

  Similarly, when the number of sheet-like pulp 2 actually counted by the pulp counting means 35 is larger than the preset number of conveyed sheet-like pulp 2, the conveying means 8 is stopped. Also good. Thus, by stopping the conveying means 8 and temporarily interrupting the conveyance of the sheet-like pulp 2, the excessive supply of the sheet-like pulp 2 is prevented, and a certain amount of the sheet-like pulp 2 is dissolved in a certain time. The crushed kneader 15 can be supplied.

  In the multi-feed state, it may be difficult to count the number of sheet-like pulp 2 actually conveyed using only the pulp counting means 35, but if the displacement sensor 37 is also used, The number of conveyed sheet-like pulp 2 can be counted more accurately.

  As described above, the process shown in FIG. 1 or 3 is repeated depending on whether the uppermost sheet-like pulp 2 is the small pulp 2b or the large pulp 2a.

  Here, when the order of stacking the small pulp 2b and the large pulp 2a mounted on the mounting table 14 is random, if both the small pulp 2b and the large pulp 2a are transported at the same transport speed, in a certain time. There is a possibility that the total amount of the sheet-like pulp 2 supplied to the pulverization kneader 15 and the total amount of the sheet-like pulp 2 supplied to the pulverization kneader 15 at another predetermined time may be different. Therefore, when the sheet pulp 2 determined by the size determination sensor 11 is small, the control unit 17 controls the transport unit 8 so as to increase the transport speed of the sheet pulp 2. On the contrary, when the sheet pulp 2 determined by the size determination sensor 11 is large, the control unit 17 controls the transport unit 8 so as to decrease the transport speed of the sheet pulp 2. In this way, even if the size of the sheet-like pulp 2 is different, a certain amount of the sheet-like pulp 2 can be supplied to the crushing kneader 15 in a certain time.

  In addition, when the amino resin molding material is manufactured, since the blending of the amino resin and the pulverized pulp is performed based on the weight ratio, only the number of the sheet-like pulp 2 supplied to the pulverization kneader 15 is grasped. Inconvenient. Therefore, the weight of each size of the sheet-like pulp 2 is set in the storage unit 36 or the like in advance. And first, the number of sheets of sheet-like pulp 2 of each size obtained by the pulp counting means 35 and the size discrimination sensor 11, and the weight per sheet of sheet-like pulp 2 of each size set in advance, Are multiplied to calculate the total weight for each size of the sheet-like pulp 2. Specifically, the total weight of the conveyed small pulp 2b is calculated by multiplying the number of conveyed small pulps 2b and the weight of each small pulp 2b, and the number of conveyed large pulps 2a is large. The total weight of the transported large pulp 2a is calculated by multiplying the weight per pulp 2a. Next, the total weight of all the sheet-like pulps 2 is calculated by adding them together, and the total weight obtained in this way is stored in the storage unit 36. If it does in this way, the total weight of the sheet-like pulp 2 supplied to the crushing kneader 15 can be grasped, and it can be easily managed whether there is any abnormality in the blending ratio with the amino resin. is there.

  However, since the weight per sheet of each size of the sheet-shaped pulp 2 set in advance is not an actual measurement value, the total weight of the sheet-shaped pulp 2 supplied to the crushing kneader 15 should be accurately grasped. May not be possible. Therefore, in such a case, a load cell (not shown) may be provided in the transport unit 8 to provide a weight measuring function. And whenever the sheet-like pulp 2 is conveyed with the conveyance means 8, and the weight is measured and this measured value is integrated | accumulated, the total weight of all the sheet-like pulp 2 supplied to the crushing kneader 15 will be obtained. The total weight obtained in this way is stored in the storage unit 36. If it does in this way, the total weight of the sheet-like pulp 2 supplied to the crushing kneader 15 can be grasped more accurately, and it can be easily managed whether there is an abnormality in the blending ratio with the amino resin. It can be done.
