Description

[Technical field]

[0001] The present invention relates to an aperture device. [Background technology]

[0002] In processing plants, for example, viscous raw materials (hereinafter also referred to as contents) arrive sealed in bags, and a squeezing device is used to squeeze out the contents from the bags without leaving any residue.

[0003] As an example of such a squeezing device, Patent Document 1 discloses a device that is axially attached to support holes formed in each of a pair of opposing side portions, and is equipped with a winding roll and a pressing member formed with a diameter larger than the support holes, and squeezes the contents through a bag through the gap formed between them.

[0004] However, in the squeezing device according to Patent Document 1, the take-up roll and the pressing member are larger in diameter than the support hole, so they get caught on the side and can barely move in the axial direction. Therefore, the take-up roll and the pressing member cannot be removed without disassembling the device, and even if the raw material adheres to them, they cannot be easily removed and thoroughly washed. As a result, there is a problem that it is difficult to keep them clean. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2007-290729 A Summary of the Invention [Problem to be solved by the invention]

[0006] Therefore, a main object of the present invention is to make it possible to easily remove the squeeze rod without disassembling the device. [Means for solving the problem]

[0007] In other words, the squeezing device of the present invention comprises a pair of supports fixed at a distance from one another to a fixed object such as a workbench, and a pair of squeezing rods supported between the pair of supports, wherein the pair of supports have support holes formed on their opposing surfaces, and the support hole of at least one of the supports penetrates from the opposing surface to the opposite surface, and the squeezing rods are configured to be movable so as to pass through the support hole that penetrates from a support position where both ends are inserted and supported in the support holes.

[0008] According to the present invention, the squeezing rod is configured to be movable in the axial direction so as to pass through the support hole penetrating from the support position, so that it can be easily removed by removing it from the support hole penetrating from the support position without disassembling the device. As a result, the squeezing rod can be washed thoroughly and kept clean. In addition, with such a configuration, for example, one end of the squeezing rod can be inserted from the support position into the support hole penetrating from the other end and removed from the support hole. As a result, the other end that has been removed can be shifted to a position not facing the support hole, and the one end can be removed from the support hole, so that it can be easily removed without disassembling the device. With such a method of removal, the center of the squeezing rod, to which the raw material is likely to adhere, does not come into contact with the support, and the support can be kept clean.

[0009] In other words, the squeezing rod may be configured to be movable between the support position and a removal position in which one end is inserted into the through support hole and the other end is removed from the support hole. In this case, the squeezing rod may be configured to shift the other end to a position not facing the support hole in the removal position.

[0010] Furthermore, if the pair of supports are separate, the distance between them can be freely adjusted to match the width of a workbench, for example.

[0011] In addition, if the squeezing rod is a straight type, it will not get caught on the support when it is moved in the axial direction, making it easier to remove. Also, since it can be formed simply by cutting a long rod, manufacturing costs can be reduced.

[0012] At least one end of each of the squeeze rods may be inserted into a common support hole, and the cross-sectional shape of the support hole may be circular.

[0013] With this configuration, the squeeze rods rotate along the inner circumferential surface of the support hole while remaining parallel to one another, which changes the opening direction of the gap according to the direction in which the bag is pulled, making it easier to remove the bag.

[0014] In addition, the squeezing device of the present invention comprises a pair of supports fixed at a distance from one another to a fixed object such as a workbench, and a pair of squeezing rods supported between the pair of supports, wherein the pair of supports have support holes formed on their opposing surfaces, and the squeezing rods are configured to be movable between a support position in which both end portions are inserted and supported in the support holes, and a removal position in which one end portion remains inserted in the support hole while the other end portion is removed from the support hole.

[0015] According to the present invention, the squeezing rod can be moved to the removal position, and in this position, the other end is shifted to a position where it does not face the support hole, and one end is removed from the support hole, allowing it to be easily removed without disassembling the device. As a result, the squeezing rod can be washed thoroughly and kept clean. Also, by removing it in this manner, the center of the squeezing rod, which is prone to adhesion of ingredients, does not come into contact with the support, and the support can also be kept clean. Effect of the Invention

[0016] According to the present invention configured in this manner, the squeezing rod can be easily removed without disassembling the device. [Brief description of the drawings]

[0018] <Embodiment> Hereinafter, an embodiment of the aperture device according to the present invention will be described.

[0019] The squeezing device according to the present invention is for squeezing out viscous raw materials sealed in bags in, for example, a factory, and is used by being directly or indirectly fixed to an object to be fixed. Examples of the object to be fixed include a workbench, a processing device, and a wall of a house. Needless to say, the device can be used outside of factories.

[0020] The squeezing device 100 of this embodiment is fixed directly to the workbench X, and as shown in Figure 1, comprises a pair of supports 10 fixed to the workbench X with a gap between them, and a pair of squeezing rods 20 supported by being stretched between the pair of supports 10, and as shown in Figure 4, the contents Z are squeezed out through a bag Y between the pair of squeezing rods 20.

[0021] The pair of supports 10 are separate bodies having the same shape as shown in Fig. 1. In this embodiment, they are fixed to the side of the workbench X, but the present invention is not limited to this and they may be fixed to the top or bottom surface, for example. Specifically, as shown in Figs. 2 and 3, the support 10 includes a support portion 11 and a base 12 for fixing the support portion 11 to the workbench, and a support hole 11h is formed in the support portion 11.

[0022] The support hole 11h penetrates from the opposing surface 11a of the supports 11 to the opposite surface 11b, and has a circular cross section taken in a direction perpendicular to the penetration direction. The support hole 11h is formed to have the same diameter from the opposing surface 11a to the opposite surface 11b.

[0023] The base 12 is provided with a plate-shaped magnet 12a on the surface that comes into contact with the workbench X, and is detachably fixed to a metal part of the workbench X by the magnetic force of this magnet. Here, "detachable" means that it can be removed with one touch without removing screws or the like. For the magnet, for example, a neodymium magnet with strong magnetic force is used. The support 10 may be formed from a hard material such as metal or resin.

[0024] The pair of squeezing rods 20 are straight type, and the cross section cut in the direction perpendicular to the axial direction is circular. The squeezing rod 20 in this embodiment is a cylindrical body, but it does not necessarily have to be a cylindrical body and may be a solid body. The squeezing rod 20 may be made of a hard material such as metal or resin.

[0025] In this embodiment, the pair of squeezing rods 20 have the same diameter, but they do not necessarily have to be the same diameter and may have different diameters. Here, the diameter of the squeezing rod 20 is smaller than the diameter of the support hole 11h. Specifically, the sum of the diameters (outer diameters) of both squeezing rods 20 is smaller than the diameter (inner diameter) of the support hole 11h, so that both squeezing rods 20 can be inserted into the common support hole 11h. In addition, when both squeezing rods 20 are inserted into the common support hole 11h, a gap g is formed between them that opens in a direction intersecting (perpendicular to) the opposing direction of both squeezing rods 10 as viewed from the axial direction, and the content Z is squeezed out through the bag Y through this gap g.

[0026] 7(a), the squeezing rod 20 is capable of moving in the axial direction from support position A, where both ends 20a, 20b are inserted and supported in support holes 11h, to pass through any of the penetrating support holes 11h. More specifically, the squeezing rod 20 is configured so that the entirety of the squeezing rod 20 can pass through the penetrating support hole 11h.

[0027] As shown in FIG. 7(b), the squeezing rod 20 is configured to be movable between the support position A and a removal position B where the other end 20b is removed from the support hole 11h while the one end 20a is inserted into the support hole 11h. That is, the squeezing rod 20 can be moved from the support position A to a removal position B where the other end 20b is removed from the support hole 11h by inserting the one end 20a further into the support hole 11h. As shown in FIG. 7(c), the squeezing rod 20 is configured to shift the other end 20b removed from the support hole 11h to a position not facing the support hole 11h when moved to the removal position B. At this position, the squeezing rod 20, which was approximately parallel to the central axis direction of both support holes 11h at the support position A, is tilted with respect to the central axis direction. In other words, the support hole 11h has an inner diameter longer than the outer diameter of the squeezing rod 20, and a gap is formed between the support hole 11h and the squeezing rod 20 inserted into the support hole 11h. Therefore, when the squeezing rod 20 is rotated in a direction perpendicular to its axial direction with one end 20a as a fulcrum at the removal position B, the one end 20a will tilt until it comes into contact with the inner circumferential surface of the support hole 11h and rotation is restricted. More specifically, the squeezing rod 20 rotates and tilts until one end 20a comes into contact with the support hole 11h at two points, the back side and the opening side.

[0028] In the present embodiment, squeezing rod 20 is long enough that both ends 20a, 20b protrude from opposite surface 11b of support 10 when moved to support position A, but this length is not essential. For example, both ends 20a, 20b may be long enough to fit within support hole 11h when moved to support position A.

[0029] Next, a method of using the aperture device 100 according to this embodiment will be described with reference to FIGS.

[0030] First, one end of the bag Y is sandwiched in the gap g between a pair of squeeze rods 20. The other end of the bag Y is left open. Then, as shown in Figures 4 and 5, one end of the bag Y is pulled in a predetermined direction (upward in Figures 4 and 5) and the entire bag Y is passed through the gap g. This causes the contents Z to be squeezed out from the other end of the bag Y.

[0031] Here, when the direction in which the bag Y is pulled is changed while the bag Y is being pulled out of the gap g, as shown in Fig. 6, the opening direction of the gap g changes accordingly to match the pulling direction. In more detail, for example, when the bag Y is pulled straight up as shown in Fig. 5, the gap g also opens straight up. From this state, when the pulling direction of the bag Y is changed and it is pulled diagonally upward as shown in Fig. 6, both squeezing rods 20 slide along the inner circumferential surface of the support hole 11h while maintaining a parallel state, and as a result, the direction of the gap g changes so that it opens diagonally upward.

[0032] Next, a method for removing the squeezing rod 20 from the squeezing device 100 according to this embodiment will be described with reference to FIG.

[0033] In this embodiment, since both of the pair of support holes 11h are through holes, the squeezing rod 20 can be removed by simply moving it in the axial direction and pulled out from both support holes 11h. As another method of removal, first, as shown in Fig. 7(a), the squeezing rod 20 is placed at support position A, and as shown in Fig. 7(b), one end 20a of the squeezing rod 20 is further inserted into the support hole 11h, and the other end 20b is removed from the support hole 11h. From this state, as shown in Fig. 7(c), the other end 20b removed from the support hole 11h is shifted so that it does not face the support hole 11h, and the squeezing rod 20 is tilted as a whole, and then one end 20a can be pulled out from the support hole 11h and removed.

[0034] According to this embodiment, since at least one of the support holes 11h is a through hole, the entire squeezing rod 20 can be passed through the support hole 11h, and can be easily removed without disassembling the device. As a result, the squeezing rod 20 can be washed thoroughly and kept clean. In addition, since the squeezing rod 20 can be moved to the removal position B, the other end 20b can be shifted to a position not facing the support hole 11h at this position B, and one end 20a can be removed from the support hole 11h, and can be easily removed without disassembling the device. By removing it in this manner, the center of the squeezing rod 20, to which the contents Z are likely to adhere, does not come into contact with the support 10, and the support 10 can also be kept clean.

[0035] In this embodiment, both ends 20a, 20b of both squeezing rods 20 are inserted into a common support hole 11h, and the support hole 11h has a circular cross section, so that when the direction in which the bag Y is pulled is changed, the direction of the gap g between both squeezing rods 20 changes accordingly. This reduces the resistance that occurs when the bag Y is pulled out of the gap g.

[0036] In addition, in this embodiment, the squeezing rod 20 is a cylindrical body, so it is light and can be easily removed even by a worker with little strength.

[0037] In addition, since the support hole 11h has a circular cross section, its inner peripheral surface tapers toward the pulling direction when viewed from the axial direction. As a result, when the bag Y is pulled, both squeeze rods 20 move toward each other along the inner peripheral surface of the support hole 11h. This increases the force that pinches the bag Y, making it easier to squeeze out the contents Z. Since the support hole 11h has a circular cross section, this state is maintained even if the pulling direction changes.

[0038] <Other embodiments> The aperture device according to the present invention is not limited to the aspects of the above-described embodiment. For example, in the above-described embodiment, the pair of supports are separate, but they do not have to be separate. For example, the bases may be connected to each other to form an integrated unit.

[0039] In the above embodiment, the support holes of both supports are through holes, but the present invention is not limited to this. For example, the support holes of one or both supports may be bottomed and closed on the opposite surface.

[0040] In addition, in the above embodiment, a pair of squeezing rods is inserted into a common support hole, but, for example, two support holes may be formed in the support body, and a pair of squeezing rods may be inserted into separate support holes.

[0041] In the above embodiment, the squeeze rod is of a straight type, but the present invention is not limited to this. For example, only the ends that are inserted into the support holes may have a small diameter.

[0042] The cross-sectional shape of the squeeze rod is not limited to a circle, but may be, for example, a polygon or an ellipse. The cross-sectional shape of the support hole is also not limited to a circle, but may be, for example, a polygon or an ellipse.

[0043] Also, as shown in Fig. 8, for example, three or more supports 10 may be installed at intervals, and a pair of squeezing rods 20 may be inserted into the support holes 11h. In this case, at least one of the supports 10 at both ends and the supports 10 disposed between the supports 10 at both ends must each have a through hole. With this configuration, squeezing work can be performed between adjacent supports 10, allowing multiple people to work simultaneously.

[0044] Furthermore, the present invention is not limited to the above-described embodiments, and it goes without saying that various modifications are possible without departing from the spirit of the present invention. [Explanation of symbols]
