Description

  The present invention relates to an apparatus for manufacturing a vibration sieve machine.

The vibration sieving machine includes a sieving frame that vibrates by driving means (see, for example, Patent Document 1). The sieving frame is configured by fixing a net member to an annular frame member. Conventionally, in a sieving frame used in this vibration sieving machine, the mesh member is held on four sides by clamps, and tension is adjusted by pulling the clamps outward. The net member whose tension is adjusted is fixed to the frame member by, for example, adhesion.
However, when the net member is held by a clamp as in the prior art, it is difficult to hold the net member with a large force. This is because the mesh member is assumed to be made of a resin such as polyamide resin, and the holding force is set so as not to cause damage to the mesh member. Therefore, when the clamp holding the mesh member is pulled outward, the tensile force acts toward the outside of the clamp, that is, in the direction perpendicular to the direction in which the clamp sandwiches the mesh member. It may come off from the member. Accordingly, it is difficult to set a tension exceeding the holding force, and there is a problem that a metal net member that requires a large holding force such as stainless steel cannot be assembled.

No. 8-1025

  Accordingly, an object of the present invention is to provide an apparatus for manufacturing a vibration sieve machine in which a mesh member is assembled with a desired tension regardless of the material of the mesh member.

According to another aspect of the present invention, there is provided a vibration sieving machine manufacturing apparatus, comprising: a holding portion that holds a mesh member formed in a mesh shape; and a reciprocating movement in an axial direction of the holding portion inside the holding portion. By pushing the frame member supporting portion that supports the frame member and the mesh member held by the holding portion together with the frame member supported by the frame member supporting portion into one axial direction of the holding portion. A tension adjusting unit that adjusts the tension of the mesh member.
According to this configuration, the tension of the net member held by the holding unit is adjusted by the tension adjusting unit pushing the net member together with the frame member supported by the frame member support unit in one of the axial directions of the holding unit. The That is, the holding member that holds the mesh member sandwiched and held is not pulled toward the outside, that is, the direction in which the holding unit is perpendicular to the direction in which the mesh member is sandwiched, but the mesh member is in the axial direction of the holding portion, that is, The tension | tensile_strength of a mesh member comes to be adjusted by extending a holding | maintenance part along the direction which pinches | interposes a mesh member. Therefore, even if a large pulling force for adjusting the tension acts on the net member, the pulling force acts in a direction in which the holding member sandwiches the net member, and thus the holding unit is not easily detached from the net member. As a result, for example, even if the net member is a metal net member that requires a large holding force, the tension can be adjusted by applying a large pulling force. Instead, the net member can be assembled with a desired tension.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
As shown in FIGS. 1 and 2, the vibration sieve manufacturing apparatus 10 (hereinafter simply referred to as the manufacturing apparatus 10) includes a holding unit 11, a frame member support unit 12, and a tension adjusting unit 13. Has been. In addition, this manufacturing apparatus 10 can also be regarded as an apparatus for manufacturing a sieve frame F (see FIG. 3D), which is one of components of a vibration sieve machine (not shown), that is, a manufacturing apparatus for a sieve frame.
The holding unit 11 includes an upper holding frame 14, a lower holding frame 15, and a clamp 16. Both the upper holding frame 14 and the lower holding frame 15 are formed in an annular shape having a rectangular cross section when viewed in the circumferential direction, and face each other in the axial direction of the holding portion 11 (in this case, the vertical direction). Superimposed. The clamp 16 includes a lower clamping arm 16a, an upper clamping arm 16b, and a rotating pin 16c for adjusting the holding force. The lower clamping arm 16a has a distal end portion (free end portion) bent upward. The upper clamping arm 16b has a distal end portion (free end portion) that is bent downward, and is rotatably provided at a substantially central portion of the lower clamping arm 16a. The distal end portion of the lower sandwiching arm 16a and the distal end portion of the upper sandwiching arm 16b are opposed to each other. The rotation pin 16c adjusts the amount of rotation of the upper clamping arm 16b relative to the lower clamping arm 16a in accordance with the amount of rotation thereof, whereby the clamping force of the clamp 16 (the upper holding frame 14 and the lower holding frame 15 are held by the holding unit 11). Adjust the tightening force along the axial direction. In FIG. 2, the clamp 16 is shown in a transparent manner, and an internal rotation structure and the like are also shown.

  The holding unit 11 configured as described above is configured so that the mesh member A (see FIG. 3, a member formed in a net shape by weaving a large number of wire rods) constituting the sieve net, which is a part of the sieve frame F, is the upper holding frame 14. And the lower holding frame 15, and the upper holding frame 14 and the lower holding frame 15 sandwiching the net member A in this way are tightened by a plurality of clamps 16. As a result, the holding unit 11 holds the mesh member A sandwiched in the axial direction of the holding unit 11 (in this case, the vertical direction). The holding force of the mesh member A by the holding portion 11 can be adjusted as appropriate by adjusting the amount of rotation of the rotation pin 16c of the clamp 16. In order to hold the net member A evenly, the plurality of clamps 16 are preferably arranged at equal intervals in the circumferential direction of the holding portion 11.

The frame member support portion 12 includes two rail portions 17 that extend in a horizontal direction (direction perpendicular to the axial direction of the holding portion 11) perpendicular to each other, and slide portions that are provided at both ends of each rail portion 17, respectively. 18. Each slide portion 18 is provided to be slidable on each rail portion 17 along the direction in which the rail portion 17 extends. Each slide portion 18 is configured such that its position (slide position on the rail portion 17) can be fixed by a stopper 19 respectively. Further, support metal fittings 20 are attached to the upper surface of the tip of each slide portion 18.
The frame member support portion 12 configured in this manner supports the annular frame member W (see FIG. 3) that constitutes the outer frame that is a part of the sieve frame F by locking each support fitting 20. . In this case, the frame member support portion 12 supports the frame members W having different diameters by adjusting the slide position of each slide portion 18 having the support metal fitting 20 according to the diameter size of the frame member W to be supported. Is possible.

  The tension adjusting unit 13 is configured to move the rectangular plate-shaped lifting platform 22 up and down (reciprocate vertically in the axial direction of the holding unit 11) by the lifting mechanism unit 21 including a known hydraulic lift. An intermediate base 23 formed in a rectangular parallelepiped shape by a plurality of frame materials is placed in the central part of the upper part of the lift base 22. The frame member support portion 12 described above is installed on the upper surface of the intermediate base 23. That is, the frame member support portion 12 is configured to be indirectly placed on the upper surface of the lifting platform 22 with the intermediate platform 23 interposed therebetween. Wheels 21 a are attached to the four corners of the bottom of the elevating mechanism 21. A handle portion 21 b is attached to the lifting mechanism portion 21.

The elevating mechanism 21 is fitted into and fixed to the center of the bottom of the substantially rectangular parallelepiped outer frame member 13 a that forms the outline of the tension adjuster 13. The outer frame member 13a is also formed of a plurality of frame members, of which, at the outer edge of the outer frame member 13a, the upper end portions of the four corner frame members 13a1 extending in the vertical direction are fixed to the holding portions, respectively. A fixing mechanism 24 is provided.
The fixing mechanism portion 24 includes a main body portion 24a and a fixing portion 24b. The main body 24a is formed in a rectangular parallelepiped shape as a whole, and its longitudinal direction is the center of the frame member support 12 (the portion where the two rails 17 intersect, in other words, the frame member support 12 is arranged so as to be directed toward the center portion of the frame member W supported by 12. The fixing portion 24b is provided on the main body portion 24a so as to be slidable along the longitudinal direction of the main body portion 24a. The position of the fixing portion 24b (sliding position on the main body portion 24a) can be fixed by rotating the position fixing lever 24c.

The holding part 11 holding the mesh member A as described above is fixed to the tension adjusting part 13 by the plurality of (in this case, four) fixing mechanism parts 24. In this case, each fixing mechanism 24 adjusts the sliding position of the fixing part 24b according to the diameter of the holding part 11 (the upper holding frame 14 and the lower holding frame 15) to be fixed, thereby holding different diameter dimensions. The part 11 can be fixed.
When the holding portion 11 is fixed to the fixing mechanism portion 24 of the tension adjusting portion 13 in this way, the fixing mechanism portion 24 is the outer edge portion of the outer frame member 13a (outer outline of the tension adjusting portion 13), that is, the outer frame. Since the frame member support portion 12 is positioned outside the frame member support portion 12 disposed inside the member 13a (tension adjusting portion 13), the frame member support portion 12 is located inside the holding portion 11 fixed to the fixing mechanism portion 24. Will come to be located. And the frame member support part 12 is in the state which can be reciprocated along the axial direction (up-down direction) of the said holding | maintenance part 11 inside the holding | maintenance part 11 with the raising / lowering mechanism part 21 raising / lowering the raising / lowering stand 22. Become.

  Next, FIG. 3 shows the operation when the sieve frame F which is a part of the vibration sieve machine (not shown) is manufactured by the vibration sieve machine manufacturing apparatus 10 having the above-described configuration (the sieve frame F and thus the manufacturing process of the vibration sieve machine). This will be described with reference to (a) to (d). 3A shows a fixing process for fixing the holding portion 11, FIG. 3B shows a contact process for bringing the frame member W into contact with the mesh member A, and FIG. FIG. 3D shows a finishing process (cutting process) in which the screen frame F is formed by cutting the net member A. FIG. 3A to 3D, illustration of the tension adjusting unit 13, the fixing mechanism unit 24, the elevating mechanism unit 21, the elevating platform 22, and the like is omitted.

  3A shows a state in which the holding portion 11 holding the mesh member A is fixed to the fixing mechanism portion 24 of the tension adjusting portion 13, and at this time, the frame member supporting portion that supports the frame member W is shown. 12 is lowered to at least a position lower than the fixing mechanism 24 before fixing the holding unit 11 to the tension adjusting unit 13 (fixing mechanism 24). Then, in this case, an adhesive is applied to the portion (in this case, the upper surface portion) of the frame member W supported by the frame member support portion 12 that comes into contact with the mesh member A as an adhesion preparation process.

From the state shown in FIG. 3A, the lifting platform 22 is lifted by the lifting mechanism 21 of the tension adjusting unit 13, whereby the frame member W supported by the frame member supporting unit 12 is moved to the axis of the holding unit 11. Move upward in one of the directions. Then, as shown in FIG. 3B, the upper surface of the frame member W, that is, the surface to which the adhesive is applied comes into contact with the lower surface of the net member A. Further, when the frame member W supported by the frame member support portion 12 is moved upward by the elevating mechanism portion 21 of the tension adjusting portion 13, the holding portion 11 holds the frame member W as shown in FIG. The mesh member A is pushed upward together with the frame member W supported by the frame member support part 12 in one of the axial directions of the holding part 11. At this time, as the frame member W moves upward, the mesh member A is gradually pulled in the upward direction (upward in one of the axial directions of the holding portion 11). By adjusting the tension, the tension of the mesh member A is adjusted.
When a desired tension is applied to the mesh member A, the state is maintained until at least the adhesive is sufficiently dried and the mesh member A is fixed to the frame member W. Then, as shown in FIG. 3 (d), when a portion of the mesh member A outside the frame member W is cut, a sieve frame F in which the mesh member A is fixed to the frame member W is manufactured.

  As described above, according to the present embodiment, the frame member support portion 12 that supports the annular frame member W is provided inside the holding portion 11 that holds the mesh member A formed in a mesh shape. It was provided to be able to reciprocate in the axial direction. The mesh member A held by the holding unit 11 is one of the holding member 11 in the axial direction together with the frame member W supported by the frame member supporting unit 12 by the lifting mechanism unit 21 of the tension adjusting unit 13. The tension of the mesh member A was adjusted by pushing upward. That is, by adjusting the relative positional relationship between the mesh member A held by the holding portion 11 and the frame member W supported by the frame member supporting portion 12 along the axial direction of the holding portion 11, The tension of the member A was adjusted.

  According to this configuration, the tension of the net member A held by the holding unit 11 is such that the tension adjusting unit 13 moves upward along with the frame member W supported by the frame member support unit 12 by the lifting mechanism unit 21 ( Adjustment is made by pushing the holding part 11 into one side in the axial direction. That is, rather than pulling the holding portion 11 holding the mesh member A sandwiched outward, that is, in the direction perpendicular to the direction in which the holding portion 11 sandwiches the mesh member A (in this case, the horizontal direction) The tension of the mesh member A is adjusted by extending the mesh member A along the axial direction of the holding portion 11, that is, the direction in which the holding portion 11 sandwiches the mesh member A (in this case, the vertical direction). become. Therefore, even if a large pulling force for adjusting the tension acts on the mesh member A, all or most of the pulling force acts in the direction in which the retaining member 11 sandwiches the mesh member A. 11 becomes difficult to remove from the net member A. Thereby, for example, even if the net member A is a metal net member that requires a large holding force, the tension can be adjusted by applying a large tensile force. Regardless, the mesh member A can be assembled to the frame member W with a desired tension regardless of whether the mesh member A is made of a resin such as polyamide resin or a metal such as stainless steel.

In addition, according to the present embodiment, the tension adjusting unit 13 performs the adhesion preparation process on the portion (in this case, the upper surface portion) of the frame member W supported by the frame member support unit 12 that contacts the net member A. In the state (in this case, the state where the adhesive is applied), the elevating mechanism portion 21 pushes the mesh member A together with the frame member W upward (one in the axial direction of the holding portion 11).
According to this configuration, since the adhesive is applied to the portion of the frame member W that contacts the mesh member A, it is only necessary to push the mesh member A together with the frame member W upward (one in the axial direction of the holding portion). The mesh member A can be fixed to the frame member W with its tension adjusted, thereby making it easier to manufacture the sieve frame F assembled with the mesh member A with a desired tension. Thus, it is possible to easily manufacture a vibration sieving machine including the sieving frame F.

In addition, this invention is not limited only to one embodiment mentioned above, It can apply to various embodiment in the range which does not deviate from the summary, For example, it can deform | transform or expand as follows. .
By appropriately changing and setting the height dimension of the intermediate base 23, the reciprocating range of the frame member support portion 12 with respect to the holding portion 11 holding the mesh member A, in other words, supported by the frame member support portion 12 is supported. The reciprocating range of the frame member W can be adjusted as appropriate. If the frame member W supported by the frame member support portion 12 can be sufficiently raised above the holding portion 11 holding the mesh member A (one in the axial direction), the intermediate base 23 is It is good also as a structure which mounts the frame member support part 12 directly on the upper surface of the raising / lowering stand 22, without installing.

The frame member support portion 12 is not limited to the configuration including the two rail portions 17. For example, the frame member support portion 12 may be configured to include one rail portion 17 or may be configured to include three or more rail portions 17. Good.
The tension adjusting unit 13 is installed above the holding unit 11 holding the mesh member A, and the tension of the mesh member A is adjusted by pushing the mesh member A downward with the frame member W (the other in the axial direction of the holding unit). It is good also as composition to do.

The tension adjusting unit 13 is not limited to the lifting mechanism unit 21 formed of a hydraulic lift, and various lifting mechanisms such as a mechanism that moves up and down by rotating the lifting platform 22 itself can be employed. In short, any mechanism that reciprocates the lifting platform 22 along the axial direction of the holding unit 11 may be used. Further, the elevating mechanism unit 21 may be an electric type or a manual type.
The upper holding frame 14 and the lower holding frame 15 are not limited to a rectangular cross section, and may be configured in various cross sectional shapes such as a circular cross section and an elliptical cross section. It is also possible to configure either the upper holding frame 14 or the lower holding frame 15 in a rectangular cross section and the other in a circular cross section. In short, any shape that can sandwich the net member A along the axial direction of the holding portion 11 may be used.

The clamp 16 can also be composed of, for example, a clip. The point is that the upper holding frame 14 and the lower holding frame 15 sandwiching the mesh member A may be configured to be sandwiched along the direction in which the upper retaining frame 14 and the lower holding frame 15 sandwich the mesh member A.
The frame member W, in other words, the sieve frame F manufactured by the manufacturing apparatus 10 is not limited to an annular shape, and may be formed in an elliptical shape or a polygonal shape as long as it is annular. In this case, the shape of the holding portion 11 can be changed as appropriate in accordance with the shape of the frame member W (the shape of the sieve frame F to be manufactured). Moreover, the holding part 11 does not need to be annular, for example, the holding part is constituted by a plurality of holding parts (clamp-like parts), and a plurality of outer edge portions of the mesh member A are formed by the plurality of holding parts. It is good also as a structure hold | maintained partially.

  The adhesion preparation process is not limited to the process of applying an adhesive, and may be a process of attaching a double-sided adhesive tape, for example. Alternatively, the net member A may be fixed to the frame member W when a desired tension is applied to the net member A without performing the adhesion preparation process. That is, in the fixing step shown in FIG. 3A, the frame member W is moved along the axial direction of the holding portion 11 without performing an adhesion preparation process on the portion of the frame member W that contacts the mesh member A. And when desired tension | tensile_strength is provided to the mesh member A, you may fix the part which the frame member W and the mesh member A contact using various fixing methods, such as welding and brazing, for example.
