[0018]
FIGS. 9A, 9B, 9C and 9D are explanatory views showing the supply operation of the first supply mechanism.
In FIG. 9, G indicates a glass fiber.
[0019]
Next, the measurement of the glass fiber G will be described.
In addition, each slider 7A-7D exists in an advance position, and each pin 9A-9D in the 1st hopper 4 is in the state which the front-end | tips meshed | engaged, as shown to Fig.9 (a). And
Further, it is assumed that the lids 44A and 44B close the opening of the third hopper 42.
[0020]
First, the flexible container is lifted with a crane, the lid of the first hopper 4 is removed, the glass fiber G in the flexible container is put into the first hopper 4, and then the lid is attached, as shown in FIG. 9 (a). The glass fiber G is deposited on the upper side of the pins 9A and 9B.
When 300 kg of glass fiber G, for example, is supplied (introduced) into the first hopper 4 in this way, the load cell 13 is compressed by the load of the glass fiber G, and the first hopper 4 is generated by a signal obtained by compressing the load cell 13. The amount (weight) of the glass fiber G inside is displayed as 300 kg on the display unit.
[0021]
Next, when the start button of the control panel (not shown) is pressed, the hydraulic cylinders 10A and 10B are extended, and the sliders 7A and 7B are guided by the guide rails 6a and 6b to move away from each other. As shown in 9 (b), the pins 9A and 9B are retracted.
When the pins 9A and 9B retreat in this way, a lump of glass fiber G sequentially falls onto the pins 9C and 9D from between the pins 9A and 9B.
Then, when the open limit proximity switches 12A and 12B detect the detected objects, the extension of the hydraulic cylinders 10A and 10B stops.
When the hydraulic cylinders 10A and 10B are extended and stopped in this manner, the tips of the pins 9A and 9B are not positioned in the first hopper 4, and as shown in FIG. 9B, to the upper side of the pins 9C and 9D. The glass fiber G descends.
[0022]
Next, after a lapse of a short time, for example, 5 seconds, when the hydraulic cylinders 10A and 10B start to contract, the sliders 7A and 7B are guided by the guide rails 6a and 6b to move closer to the pins. 9A and 9B move forward in the glass fiber G. The contraction of the hydraulic cylinders 10A and 10B is stopped by detecting the detected objects by the closing limit proximity switches 11A and 11B.
When the hydraulic cylinders 10A and 10B are contracted and stopped in this way, the tips of the pins 9A and 9B are engaged with each other as shown in FIG. 9C, and the pins 9A and 9B are in contact with the pins 9C and 9D. For example, 60 kg of glass fiber G is accommodated. When the state shown in FIG. 9C is obtained, the first-stage weighing of the glass fiber G is started.
[0023]
First, the first-stage weighing, that is, the case where the glass fiber G is supplied while being metered from the first accommodating portion 3 to the second accommodating portion 22, will be described. The hydraulic cylinders 10C and 10D slide slowly to extend. The children 7C and 7D are guided and guided away by the guide rails 6c and 6d, and as shown in FIG. 9D, the pins 9C and 9D are slowly retracted, and the glass fiber G is inserted between the pins 9C and 9D. Are gradually dropped while being released, and are supplied into the swing box 26.
When the glass fiber G in the first hopper 4 is supplied to the swing box 26 in this way, the compression of the load cell 13 changes and the load cell 35 is also compressed, and the first and second hoppers 4 and 23 each time. The amount of the glass fiber G inside is displayed on the display unit.
[0024]
Then, when 30 kg of glass fiber G is unwound and supplied into the rocking box 26, the amount of the glass fiber G in the second hopper 23 is displayed on the display unit as 30 kg by the signal that the load cell 35 is compressed. The amount of the glass fiber G in the first hopper 4 is also displayed as 270 kg on the display unit, and the extension of the hydraulic cylinders 10C and 10D is stopped based on the detection signal of 30 kg detected by the load cell 35, so that the first hopper The supply of the glass fiber G from 4 to the second hopper 23 (swing box 26) is stopped.
When the backward movement of the pins 9C and 9D is stopped in this way, even if the space between the pins 9C and 9D is open, the glass fiber G is entangled and thus does not fall.
[0025]
Then, when the glass fiber G in the swing box 26 disappears by an operation as described later, the hydraulic cylinders 10C and 10D again slowly expand, so that the glass fiber G is dropped from the pins 9C and 9D while being slightly released. Then, the operation of feeding into the rocking box 26 is repeated.
By repeating this measuring operation, the opening limit proximity switches 12C and 12D detect the object to be detected, and the extension of the hydraulic cylinders 10C and 10D is stopped.
[0026]
Then, when the hydraulic cylinders 10C, 10D start to contract, the sliders 7C, 7D are guided by the guide rails 6a, 6b and move closer to the target, and the closing limit proximity switches 11C, 11D By detecting, the contraction of the hydraulic cylinders 10C and 10D stops.
When the hydraulic cylinders 10C and 10D are contracted and stopped in this manner, the tips of the pins 9C and 9D are engaged with each other, and the initial state without the glass fiber G between the pins 9A and 9B and the pins 9C and 9D is restored. .
[0027]
Thereafter, the glass fibers G are sequentially supplied from the first accommodation unit 3 to the second accommodation unit 22 by sequentially repeating the above-described operations.
And since the remaining amount of the glass fiber G in the 1st accommodating part 3 is sequentially displayed on a display part by the output of the load cell 13, by looking at a display part, the glass fiber G in the 1st accommodating part 3 is displayed. The remaining amount can be confirmed, and the glass fiber G can be replenished into the first housing 3 at an appropriate time.
[0028]
Next, the second-stage weighing, that is, the case where the glass fiber G is supplied while being metered from the second accommodating portion 22 to the third accommodating portion 41 will be described. For example, the detection that the load cell 35 detects 30 kg of glass fiber G. Based on the signal, the motor 30 is rotated to reciprocate the swing box 26, so that the glass fiber G is further broken by the round bars 25 and 28 and supplied into the third hopper 42.
When the glass fiber G in the second hopper 23 is supplied to the third hopper 42 in this way, the compression of the load cell 35 changes and the load cell 46 is also distorted, and the inside of the second and third hoppers 23 and 46 in each case. The amount of the glass fiber G is displayed on the display unit.
[0029]
Then, when 10 kg of glass fiber G is unwound and supplied into the third hopper 42, the amount of the glass fiber G in the third hopper 42 is displayed as 10 kg on the display unit by a signal distorted by the load cell 46, The amount of the glass fiber G in the second hopper 23 is also displayed as 20 kg on the display unit, and the motor 30 is stopped based on the detection signal of 10 kg detected by the load cell 46, and the second hopper 23 to the third hopper 42. The supply of the glass fiber G to is stopped.
Thus, when the motor 30 stops and the reciprocation of the swing box 26 stops, the glass fiber G does not fall.
[0030]
Then, the glass fiber G is required, and by operating the control panel, the hydraulic cylinders 45A and 45B are contracted to rotate the lids 44A and 44B to open the opening of the third hopper 42. Since 10 kg of glass fiber G in the hopper 42 is guided by the guide cylinder 47 and accommodated in a box placed on the lower side of the guide cylinder 47, the glass phi G can be used.
Since the hydraulic cylinders 45A and 45B start to expand after contracting, the opening of the third hopper 42 from which the glass fiber G is discharged is closed by the lid bodies 44A and 44B.
[0031]
When the opening of the third hopper 42 is closed by the lids 44A and 44B in this way, the closure detection mechanism detects the closure of the lids 44A and 44B, so that the closure detection mechanism outputs a closure detection signal. Based on the output of the load cell 46 based on the closing detection signal of the closing detection mechanism (a signal in which the amount of the glass fiber G in the third hopper 42 is zero) or closing of the closing detection mechanism After confirming the detection signal, the motor 30 rotates based on the operation of the control panel, whereby the operation of further breaking the glass fiber G and supplying it into the third hopper 42 is repeated.
[0032]
As described above, according to one embodiment of the present invention, the specific gravity is light (scatters like smoke), and the lower container in the flexible container or the first housing 3 is compressed and hardened. Since the glass fiber G (chopped strand) is divided twice and used (third predetermined weight) is weighed, the glass fiber G can be automatically weighed accurately with each used amount.
And since the discharge | emission mechanism 43 was provided in the 3rd accommodating part 41, the glass fiber G can be taken out from the 3rd accommodating part 41 easily.
[0033]
Further, since the anti-scattering covers 51 and 52 are provided between the first accommodating portion 3 and the second accommodating portion 22 and between the second accommodating portion 22 and the third accommodating portion 41, the glass fiber G is scattered. And the glass fiber G can be used effectively.
Further, since the load cell 13 is provided, the remaining amount of the glass fiber G in the first accommodating portion 3 can be confirmed based on the output of the load cell 13, and the glass fiber G is placed in the first accommodating portion 3 at an appropriate time. Can be replenished.
[0034]
In the above-described embodiment, an example in which the glass fibers G are sequentially supplied by being dropped from the first housing portion 3 to the second housing portion 22 and from the second housing portion 22 to the third housing portion 41 has been described. The 1st accommodating part 3 and the 2nd accommodating part 22 are set apart in the horizontal direction, are covered with a scattering prevention mechanism (scattering prevention cover), and the first accommodating part 3 is a transfer mechanism that moves the glass fiber G by the flow of air. The glass fiber G may be transferred from the second storage unit 22 to the second storage unit 22, or similarly, the glass fiber G may be transferred from the second storage unit 22 to the third storage unit 41.
With such a configuration, the overall height of the apparatus can be reduced.
[0035]
In addition, the example in which the glass fiber G can be sequentially supplied from the upstream accommodating portion to the downstream accommodating portion has been described, but the weighing signal having a predetermined weight is not detected from the lower weighing mechanism, and the inside of the upper accommodating portion is not detected. When the glass fiber G is no longer present, the measurement can be resumed in the same manner after the glass fiber G is supplied to the upper accommodating portion while keeping the lower accommodating portion in that state.
[0036]
【The invention's effect】
As described above, according to the present invention, a fiber (chopped strand) that has a light specific gravity (scatters like smoke) and that is compressed and hardened in the lower portion of the flexible container or the first housing portion. Since the amount of use (third predetermined weight) is weighed by dividing it into two, the fibers can be automatically weighed with a certain amount of use.
And since the discharge | emission mechanism was provided in the 3rd accommodating part, a fiber can be easily taken out from a 3rd accommodating part.
[0037]
Furthermore, since the anti-scattering mechanism is provided between the first accommodating part and the second accommodating part and between the second accommodating part and the third accommodating part, it is possible to prevent the fiber from scattering and to effectively use the fiber. Can be used.
In addition, since the first weighing mechanism is provided in the first accommodating portion, the remaining amount of the fiber in the first accommodating portion can be confirmed based on the output of the first weighing mechanism, and the fiber is appropriately placed in the first accommodating portion. Can be replenished at the time.
