DETAILED DESCRIPTION OF THE INVENTION

[0013] A quantitative powder supplying device according to one embodiment of the present invention will be described below with reference to the drawings. In the following description, the "lateral direction" will be referred to as the "front-rear direction." The "front side" refers to the side where the chute is located, and the "rear side" refers to the side where the drive source is located.

[0014] In FIG. 1, reference numeral 1 denotes a quantitative powder supplying device according to one embodiment of the present invention. The quantitative powder supplying device 1 (hereinafter also simply referred to as "device 1") includes a drive unit 1A, a container unit 1B, and a support portion 30. The drive unit 1A and the container unit 1B are configured as separate units. The device 1 includes a slide mechanism 20. In this embodiment, the slide mechanism 20 includes a guide rail 21 and a guide groove 22. In this embodiment, the device 1 further includes positioning means 23 for positioning the container unit 1B at a predetermined position on the slide mechanism 20.

[0015] Fig. 2 shows a state in which the container unit 1B is shifted from the drive unit 1A. As shown in Fig. 2, the slide mechanism 20 allows the container unit 1B to be adjacent to the drive unit 1A by inserting the container unit 1B from the front side (one side in the horizontal direction) and moving it to the rear side (the other side in the horizontal direction), and also allows the container unit 1B to be separated from the drive unit 1A by moving the container unit 1B to the front side.

[0016] 3 shows a schematic cross-sectional view of the device 1. The device 1 includes a container 5 capable of containing powder, a metering space 7 communicating with the storage space S5 of the container 5, a supply port A2 communicating with the metering space 7, a gear mechanism 3 that drives the stirring means 4 contained in the container 5, and a drive source 2 that drives the gear mechanism 3.

[0017] The device 1 is configured as a drive unit 1A by integrating a drive source 2 and a drive side gear mechanism 3A of a gear mechanism 3, while it is configured as a container unit 1B by integrating a container 5, a metering space 7, a supply port A2, and a driven side gear mechanism 3B of a gear mechanism 3.

[0018] In this embodiment, the drive unit 1A includes a drive-side unit case 15. A drive source 2 is attached to the drive-side unit case 15. In this embodiment, the drive source 2 is a motor. In this embodiment, the drive-side gear mechanism 3A is disposed inside the drive-side unit case 15.

[0019] In this embodiment, the container unit 1B includes a container-side unit case 16. A container 5 is attached to the upper end of the container-side unit case 16. An input port A1 that communicates with the storage space S5 is formed at the upper end of the container 5. In this embodiment, a discharge chute 9 is attached to the lower end of the container-side unit case 16. A supply port A2 that communicates with the metering space 7 is formed at the lower end of the discharge chute 9.

[0020] In the device 1, the drive side gear 11 of the drive side gear mechanism 3A and the driven side gear 12 of the driven side gear mechanism 3B can be meshed with each other by moving the container unit 1B rearward, while they can be separated from each other by moving the container unit 1B forward.

[0021] The drive-side gear mechanism 3A is connected to the output shaft 2a of the drive source 2. In this embodiment, the drive-side gear 11 is a drive gear connected to the output shaft 2a. However, if the drive-side gear mechanism 3A further includes an intermediate gear that meshes with the drive gear, the drive-side gear 11 can be the intermediate gear. The driven-side gear mechanism 3B has a driven-side gear 12 that meshes with the drive-side gear 11. In this embodiment, the driven-side gear 12 is an agitation gear connected to the drive shaft 4a of the agitation means 4. However, if the driven-side gear mechanism 3B further includes an intermediate gear that meshes with the agitation gear, the driven-side gear 12 can be the intermediate gear.

[0022] The stirring means 4 stirs the powder introduced into the storage space S5 of the container 5. Examples of the stirring means 4 include a rod-shaped member and a plate-shaped member.

[0023] In this embodiment, the metering space 7 communicates with the storage space S5 through an inlet 6 provided in the container-side unit case 16. In this embodiment, the metering space 7 is formed by a gear-shaped metering disk 13 and a circular space that rotatably houses the metering disk 13. Specifically, in this embodiment, the metering space 7 is a plurality of tooth-groove-shaped metering grooves 13c formed at equal intervals in the circumferential direction on the periphery of the metering disk 13.

[0024] In this embodiment, the metering disc 13 is driven by the drive source 2. In this embodiment, a metering disc gear 14 is connected to the drive shaft 13a of the metering disc 13. The driven gear 12 of the driven gear mechanism 3B meshes with the metering disc gear 14. In this embodiment, the metering disc gear 14 meshes with an agitating gear connected to the agitating means 4. However, if an intermediate gear that meshes between the metering disc gear 14 and the agitating gear is further provided, the metering disc gear 14 can mesh with the intermediate gear.

[0025] The metering space 7 communicates with the supply port A2. In this embodiment, the metering space 7 communicates with the supply port A2 through a metering port 8 provided in the container-side unit case 16.

[0026] The apparatus 1 agitates powder introduced through an inlet A1 of a container 5 in a storage space S5 of the container 5, and then measures the agitated powder at a fixed rate in a metering space 7 while discharging the powder to the outside through a supply port A2 until the powder reaches a desired amount. In this embodiment, the agitator 4 for agitating the powder and the metering disk 13 are driven by a drive source 2. Examples of powder include fillers such as carbon black, silica, talc, and clay; processing aids such as stearic acid, palmitic acid, and paraffin wax; various additives such as antioxidants; and other compounding agents used in rubber compositions, as well as other materials. However, the properties, particle size, and the like of the powder are not particularly limited as long as it can pass through the path from the inlet A1 to the supply port A2.

[0027] 4 shows a schematic side view of the drive unit 1A. In this embodiment, a guide rail 21 is provided on the drive unit 1A. The guide rail 21 extends forward from the drive-side unit case 15. In this embodiment, the guide rail 21 includes a guide wall 21a and a guide hook 21b connected to the upper end of the guide wall 21a.

[0028] Furthermore, in this embodiment, the guide rail 21 includes a guide extension portion 27. In this embodiment, the guide extension portion 27 is disposed at a predetermined position in the front-rear direction of the guide hook 21b. In this embodiment, the guide extension portion 27 is provided with a rod-shaped member 24.

[0029] 5 shows the drive unit 1A from the mating surface side with the container unit 1B. In this embodiment, the drive unit 1A has two guide rails 21. In this embodiment, the two guide rails 21 are arranged with a gap in the width direction. In this embodiment, the guide hooks 21b extend inward in the width direction so as to face each other.

[0030] In this embodiment, the drive-side unit case 15 is formed with a through-opening A3 that leads to the interior of the drive-side unit case 15. In this embodiment, the drive-side gear 11 can be seen through the through-opening A3, as shown in FIG. 5. As shown in FIG. 3, in this embodiment, the drive-side gear 11 is housed inside the drive-side unit case 15 so as not to be exposed forward of the drive-side unit case 15. Note that in this embodiment, the drive-side gear 11 may be housed inside the drive-side unit case 15 so as to be exposed forward of the drive-side unit case 15. However, in this case, the driven-side gear 12 is housed inside the container-side unit case 16 so as not to be exposed rearward of the container-side unit case 16.

[0031] 6 shows a schematic side view of the container unit 1B. In this embodiment, the guide groove 22 is provided in the container unit 1B. In this embodiment, the guide groove 22 extends in the front-rear direction on the side surface of the container-side unit case 16.

[0032] Additionally, in this embodiment, the container unit 1B is provided with a blind hole 25. In this embodiment, the blind hole 25 is provided on the side surface of the container side unit case 16. In this embodiment, the blind hole 25 is located at a position above the guide groove 22. In this embodiment, the blind hole 25 is located at a position that coincides with the rod-shaped member 24 when the container unit 1B is slid to a position where it contacts the drive unit 1A.

[0033] FIG. 7 shows the container unit 1B schematically from the mating surface side with the drive unit 1A. In this embodiment, the container unit 1B has two guide grooves 22. In this embodiment, the two guide grooves 22 are provided on the side surfaces of the container-side unit case 16. In this embodiment, the guide grooves 22 are recessed inward in the width direction so as to face each other. In this embodiment, as shown in FIG. 7, the guide grooves 22 are open on the mating surface side with the drive unit 1A (front side). This allows the guide hooks 21b of the guide rail 21 to be inserted into the guide grooves 22 from the front side.

[0034] In addition, the container unit 1B has two blind holes 25. In this embodiment, the two blind holes 25 are provided on the side surface of the container-side unit case 16. In this embodiment, the blind holes 25 are recessed inward in the width direction so as to face each other.

[0035] Furthermore, in this embodiment, the container-side unit case 16 is formed with a through-opening A4 that leads to the interior of the container-side unit case 16. In this embodiment, the driven gear 12 can be seen through the through-opening A4, as shown in Fig. 7. However, in this embodiment, the driven gear 12 is housed inside the container-side unit case 16 so as to be exposed rearward of the container-side unit case 16, as shown in Fig. 6.

[0036] FIG. 8 shows the slide mechanism 20 and the positioning means 23 in a partially enlarged and schematic cross-sectional view.

[0037] In this embodiment, the side walls 21a provided on the drive unit 1A are positioned adjacent to the side surfaces of the container unit case 16 when the container unit case 16 is guided in the front-to-rear direction, thereby restricting the widthwise movement of the container unit 1B when the container unit 1B is inserted into the drive unit 1A. Additionally, in this embodiment, the guide hooks 21b provided on the drive unit 1A are positioned in the guide grooves 22 of the container unit case 16, thereby restricting the up-down movement of the container unit 1B when the container unit 1B is inserted into the drive unit 1A.

[0038] The positioning means 23 includes a rod-shaped member 24 that passes through either the drive unit 1A or the container unit 1B, and a blind hole 25 that is provided in the other of the drive unit 1A and the container unit 1B and that fixes the rod-shaped member 24.

[0039] In this embodiment, the positioning means 23 includes a rod-shaped member 24 that passes through the drive unit 1A and a blind hole 25 provided in the container unit 1B to fix the rod-shaped member 24. Referring to Fig. 8, in this embodiment, the rod-shaped member 24 can be inserted into the blind hole 25 provided in the container unit case 16 of the container unit 1B through a through hole 26 formed in a guide extension portion 27 provided in the guide rail 21 of the drive unit 1A. This allows the container unit 1B, guided by the guide rail 21 of the drive unit 1A, to be positioned and fixed at a position where it contacts the drive unit 1A in the front-to-rear direction (lateral direction).

[0040] In this embodiment, the rod-shaped member 24 is an index plunger. In this embodiment, the rod-shaped member 24 includes a plunger 24a, a head 24b for pushing the plunger 24a, and a locking mechanism 24c. The locking mechanism 24c locks the plunger 24a in an extended state when the plunger 24a is pushed in a first time, and releases the extended state (locked state) of the plunger 24a when the plunger 24a is pushed in a second time. In FIG. 8, the locked state is indicated by a solid line, and the unlocked state is indicated by a dashed line. In this embodiment, the locking mechanism 24c is fixed to a through-hole 26 formed in the guide extension 27.

[0041] Here, an example of how to use the device 1 will be described.

[0042] 1, in this embodiment, when the container unit 1B is in a set state in contact with the drive unit 1A in the front-to-back (lateral) direction, the container unit 1B is locked (fixed) in the set state in contact with the drive unit 1A by pushing the head 24b of the rod-shaped member 24 just once. This allows the device 1 to safely and stably supply the desired amount of agitated powder.

[0043] After using the device 1, for example, when replacing the container unit 1B to supply a different powder, or when cleaning or maintaining only the drive unit 1A or the container unit 1B, the container unit 1B can be released from the locked (fixed) set state in which it is in contact with the drive unit 1A in the front-to-rear direction by pushing the head 24b of the rod-shaped member 24 just once more. This allows the container unit 1B to be separated from the drive unit 1A by pulling it forward using the slide mechanism 20.

[0044] A new container unit 1B or a container unit 1B that has been cleaned or maintained can be set in the drive unit 1A from which the container unit 1B has been separated by using the slide mechanism 20. Then, by pressing the head 24b of the rod-shaped member 24 just once, the container unit 1B is locked (fixed) in the set state in which it is in contact with the drive unit 1A. This allows the device 1 to again safely and stably supply the desired amount of agitated powder.

[0045] In the device 1, the drive unit 1A, which includes the drive system and electrical control system, and the container unit 1B, which is frequently subject to the adhesion of powder and tends to be directly affected by the powder, are configured as separate units, and the container unit 1B can be attached and detached simply by sliding it back and forth (sideways) relative to the drive unit 1A, so that only the container side portion can be easily attached and detached. For example, a configuration in which the container unit 1B slides back and forth (sideways) relative to the drive unit 1A simplifies the attachment and detachment operation, which is expected to facilitate integration into automated facilities using robots, etc.

[0046] In this embodiment, the slide mechanism 20 is configured with a simple mechanism including a guide rail 21 and a guide groove 22. In this case, the simple configuration allows only the container side portion to be easily attached and detached.

[0047] Moreover, the device 1 according to this embodiment further includes a positioning means 23 that positions the container unit 1B at a predetermined position on the slide mechanism 20. In this case, the container unit 1B can be stably positioned at the predetermined position on the slide mechanism 20.

[0048] Furthermore, as in this embodiment, the positioning means 23 preferably includes a rod-shaped member 24 that penetrates either the drive unit 1A or the container unit 1B, and a blind hole 25 provided in the other of the drive unit 1A and the container unit 1B to which the rod-shaped member 24 is fixed. In this case, the positioning of the container unit 1B can be easily performed. In this embodiment, the positioning means 23 is configured to position the container unit 1B to the drive unit 1A via a slide mechanism 20 (a guide extension 27 provided on the guide rail 21) provided in the drive unit 1A. However, the positioning means 23 may be configured to directly position the container unit 1B to the drive unit 1A without using the slide mechanism 20. In this embodiment, the rod-shaped member 24 is provided in the drive unit 1A and the blind hole 25 is provided in the container unit 1B. However, the rod-shaped member 24 may be provided in the container unit 1B and the blind hole 25 in the drive unit 1A (or vice versa).

[0049] Furthermore, as in this embodiment, it is preferable that the rod-shaped member 24 is an index plunger. In this case, the rod-shaped member 24 can be easily and stably fixed to the blind hole 25. Furthermore, even when the rod-shaped member 24 is an index plunger, it is expected to be easier to incorporate into automated facilities using robots, for example. However, the rod-shaped member 24 may also be a simple insert pin.

[0050] Furthermore, as shown in Figure 3, the device 1 of this embodiment further includes a control unit 100 that operates the drive source 2 so as to rotate the drive side gear 11 by less than one pitch when the drive side gear 11 and the driven side gear 12 do not mesh when the container unit 1B is moved from the front side (one side in the horizontal direction) to the rear side (the other side in the horizontal direction).

[0051] 5, in this embodiment, the drive unit 1A is provided with a contact sensor 101. The contact sensor 101 detects whether or not there is contact between the drive unit 1A and the container unit 1B in the front-to-rear direction (lateral direction). In this embodiment, the contact sensor 101 is provided on the mating surface of the drive-side unit case 15 with the container-side unit case 16.

[0052] The control unit 100 controls the rotation angle of the driving source 2. For example, if the driving source 2 is a stepping motor, the control unit 100 is a computer that controls the rotation angle of the stepping motor.

[0053] Figure 9 is a plan view that schematically shows an example of a state in which the driving side gear 11 and the driven side gear 12 are not meshed, and then a plan view that schematically shows a state in which the driving side gear 11 and the driven side gear 12 are meshed by controlling the rotation of the driving side gear 11.

[0054] The upper part of Figure 9 shows a state in which, when the container unit 1B is inserted into the drive unit 1A, the gear teeth 11a of the drive gear 11 and the gear teeth 12a of the driven gear 12 interfere with each other on the same line. In this case, even when the container unit 1B is inserted into the drive unit 1A, the container unit 1B does not come into contact with the drive unit 1A in the front-to-back direction (lateral direction). In this case, a signal notifying the contact from the contact sensor 101 is not input to the control unit 100 even after a predetermined time has elapsed. In this case, the control unit 100 commands the drive source 2 to rotate the drive gear 11 by less than one pitch of the gear teeth 11a of the drive gear 11. As a specific example, in an automated facility using a robot or the like, if a signal indicating contact is not input from contact sensor 101 even after a predetermined time has elapsed since the robot or the like inserted container unit 1B into drive unit 1A, control unit 100 commands the robot or the like to move container unit 1B slightly forward and also commands drive-side gear 11 to rotate, for example, half a pitch. After drive-side gear 11 has rotated half a pitch, the control unit 100 again commands the robot or the like to move container unit 1B toward drive unit 1A, thereby allowing drive-side gear 11 and driven-side gear 12 to mesh together, as shown in the lower part of FIG. 9.

[0055] Figure 10 is a plan view that schematically shows another example of a state in which the driving side gear 11 and the driven side gear 12 are not meshed, and then a plan view that schematically shows a state in which the driving side gear 11 and the driven side gear 12 are meshed by controlling the rotation of the driving side gear 11.

[0056] The upper part of FIG. 10 shows a state in which two gear teeth 11a of the drive gear 11 interfere with two gear teeth 12a of the driven gear 12 when the container unit 1B is inserted into the drive unit 1A. In this case, as in FIG. 9, even when the container unit 1B is inserted into the drive unit 1A, the container unit 1B does not come into contact with the drive unit 1A in the front-to-back direction (lateral direction). In this case, as in the case of FIG. 9, the control unit 100 commands the drive source 2 to rotate the drive gear 11 by less than one pitch (e.g., half a pitch) of the gear teeth 11a of the drive gear 11. This allows the drive gear 11 and the driven gear 12 to mesh together, as shown in the lower part of FIG. 10.

[0057] When the device 1 moves the container unit 1B from the front side (one lateral side) to the rear side (the other lateral side), if the gear teeth 11a of the drive gear 11 and the gear teeth 12a of the driven gear 12 do not mesh with each other, the device 1 may further include a control unit 100 that operates the drive source 2 to rotate the gear teeth 11a of the drive gear 11 by less than one pitch, thereby correcting the meshing between the drive gear of the drive gear mechanism and the driven gear of the driven gear mechanism. Note that the contact sensor 101 may be, for example, a position sensor.

[0058] The above is an exemplary embodiment of the present invention. Therefore, the present invention is not limited to the above embodiment and can be modified in various ways within the scope of the claims. The device 1 may include at least a drive unit 1A and a container unit 1B. For example, the support unit 30 may be a stand or vibration-isolating material that supports the drive unit 1A and the container unit 1B. The support unit 30 may also include a measuring instrument.
