Description

  The present invention relates to a container stopper capable of reliably stopping a container without giving permanent deformation such as a dent or a flaw to the container in a conveyance line for conveying the container by air conveyance.

  Conventionally, in transport lines for transporting soft or easily deformable containers such as aluminum cans, when a container shortage occurs on the upstream side of the transport path or when the container is full on the downstream side, or the transport line When a trouble occurs in the above or related machine, it is necessary to temporarily stop the container being transported. Therefore, a container stopper for appropriately stopping the container being conveyed to the conveyance line is provided to temporarily stop the flow of the container.

  For example, as shown in FIG. 5, the conventional container stopper used in this case includes a rubber elastic body 7 that is expanded by supplying compressed air F, a mounting plate 8 having both surfaces open, and the mounting plate. When the stopper 6 is disposed at opposite positions on both sides of the transfer line k and a stop operation is necessary due to trouble or the like. In other words, the compressed air F is supplied to each of the opposing elastic bodies 7 to be expanded, so that the side surfaces of the cylindrical container t are sandwiched from both sides and stopped.

  However, since the conventional container stopper 6 is opposed to both sides of the transport line k and supplies the compressed air F to each container stopper 6, the elastic body 7 is expanded. There was a problem that the container t could not be stopped as appropriate when the timing of insertion did not match or when the compressed air F did not enter one of the container stoppers 6.

  Further, when moisture m such as water droplets is attached to the side surface of the container t, the elastic body 7 is expanded by compressed air F as shown in FIG. When the surface of the body 7 is brought into contact, the container rotates in the transport direction due to friction, so that the moisture m is drawn between the side surface of the container t and the surface of the elastic body 7, and the container t A thin film r is generated between the side surface of the elastic member 7 and the surface of the elastic body 7. Then, since the thin film r serves as a lubricant and reduces the friction coefficient of the contact surface between the side surface of the container t and the surface of the elastic body 7, the container t is on the surface of the elastic body 7. There was also a problem of sliding down.

  Therefore, as a countermeasure for the phenomenon of sliding due to the thin film r, a method of increasing the number of the stoppers 6 opposed to both sides of the transport line k, or a pressure of the compressed air F supplied to the elastic body 7 is set. The stopping accuracy of the container t has been improved by a method of increasing it. However, in any of the methods, a large number of the elastic bodies 7 are brought into contact with the surface of a soft or easily deformable container t such as an aluminum can or pressed with a stronger force so that the side surface of the container t is recessed. There was a problem of giving a factor of occurrence of scratches.

  The present invention has a simple structure even in the case of the above-mentioned container to which moisture such as water droplets adheres when the container is temporarily stopped due to the occurrence of trouble in the conveyance line for conveying the flexible or easily deformable container, An object of the present invention is to provide a container stopper capable of reliably stopping the container.

  In order to solve the above-mentioned problem, the invention according to claim 1 is a container stopper provided at a position facing a side surface of the container of a conveyance line that conveys the container by air conveyance, and stops the container. A flat mounting plate in which the longitudinal direction is arranged along the transport direction of the container and is opposed to the side surface of the container, and an opening penetrating both surfaces is formed in the longitudinal direction, and the mounting A substrate stacked on the back side of the plate to close the opening, and disposed in the opening of the mounting plate, and an outer peripheral edge is sandwiched between the mounting plate and the substrate, and the side surface of the container A diaphragm provided so as to be able to advance and retreat with respect to the substrate, an introduction pipe that opens on the back side of the diaphragm and supplies compressed air to the diaphragm is formed in the substrate, and on the surface of the diaphragm, Protruding portion protruding-shape, the two sides intersecting portion and is characterized in that it is formed by positioning the upstream side of the conveying direction.

  According to a second aspect of the present invention, there is provided the container stopper according to the first aspect, wherein a plurality of the protrusions having the character shape are formed at intervals in the longitudinal direction of the diaphragm, The U-shaped projections are formed such that the one located at the center in the conveyance direction of the diaphragm has a larger thickness than the one located at the upstream and downstream ends in the conveyance direction. It is a feature.

  Furthermore, the present invention described in claim 3 is the container stopper according to claim 1 or 2, wherein the diaphragm is formed of natural rubber.

  According to the first aspect of the present invention, the container stopper is provided at a position facing the side surface of the container of the transport line, and the flat mounting plate in which the opening penetrating both surfaces is formed. And the substrate laminated on the back side of the mounting plate to block the opening, and the outer peripheral edge portion is sandwiched between the mounting plate and the substrate. The above-mentioned diaphragm is provided, and the substrate has a structure in which the introduction pipe for supplying compressed air to the diaphragm is perforated by opening on the back surface side of the diaphragm. Therefore, the number of parts constituting the container stopper is small, and even when used for a long time, the degree of failure is small. In addition, even when a failure or damage occurs during long-term use, the cause can be identified and the parts can be replaced smoothly, and the manufacturing cost and running cost can be suppressed.

  In addition, since the diaphragm is provided so as to be able to advance and retreat with respect to the side surface of the container, by supplying compressed air from the introduction pipe formed in the substrate, the width of the conveyance portion of the conveyance line can be obtained. Can be easily narrowed. Therefore, even when a sudden trouble occurs, the diaphragm can be instantly expanded to stop the container, and when the trouble is solved and the transport line is operated again, By pulling out the compressed air, the narrowed width of the transport unit can be instantaneously restored.

  Furthermore, the surface of the diaphragm is formed so that the two-side intersecting portion of the protruding portion protruding in the shape of a letter is positioned on the upstream side with respect to the conveying direction of the conveying line. When the container is temporarily stopped due to some trouble, even if water such as a water droplet adheres to the side surface of the container, a gradually reduced portion of the two-side crossing portion of the character-shaped protrusion Since the water contacts the side surface of the container sequentially, the water can be drained efficiently, and the contact area with the side surface of the container can be reduced by forming the character-shaped projections. be able to. Therefore, generation of a thin film that occurs when the moisture is drawn between the side surface of the container and the surface of the diaphragm is prevented, and the container is surely stopped without reducing the coefficient of friction of the contact surface. be able to.

  According to the second aspect of the present invention, by forming a plurality of the protrusions having a square shape in the longitudinal direction of the diaphragm at intervals, the container to be air-fed can be expanded by the expansion of the diaphragm. When the width of the transfer line is narrowed and the flow of the container is temporarily stopped, no matter which position the container is, any one of the protrusions captures the side surface of the container. The stopping accuracy can be improved.

  In addition, the plurality of square-shaped protrusions of the protrusions positioned at the central portion in the transport direction are more than the protrusions positioned at the upstream and downstream ends of the diaphragm in the transport direction. By increasing the thickness dimension, in the process until the container transported from the transport direction stops at the center of the diaphragm due to the expansion of the diaphragm, the vicinity of the end of the diaphragm in the transport direction In order to come into contact with the character-shaped protrusions with a small thickness, the hook-shaped protrusions are not caught by the character-shaped protrusions formed in The conveyance speed of the container can be reduced. Therefore, even when the container is forcibly stopped on the transfer line, the container can be prevented from overturning, and the pressure of the compressed air supplied to the diaphragm is increased and pressed against the container. There is no need to adjust the force, and the container can be reliably stopped.

  According to the third aspect of the present invention, when the compressed air is supplied from the introduction pipe provided on the substrate by forming the diaphragm with soft natural rubber, high compressed air is supplied. Even if it is not, the diaphragm can be instantaneously expanded to stop the container, and when the compressed air is removed, the diaphragm can be instantaneously returned to the original, so that the working efficiency can be improved.

  Further, by forming the diaphragm from soft natural rubber, the container can be inflated and brought into contact with the side of the container without causing dents or scratches on the side of the container. Can be stopped.

As shown in FIG. 1, the conveyance line k that conveys the container t by air conveyance has guide rails s extending in the conveyance direction W at the upper and lower positions in the longitudinal direction of the container t, and the side surface of the container t. The container t is disposed so as to be wider than the width of the container t, and is disposed at a position in contact with the lower surface of the container t and a position in which a gap is provided on the upper surface of the container t. And the container stopper 1 is attached between the guide rails s arrange | positioned by the upper part and the lower part of the one side of the container t. The container stopper is attached to a support member h provided in contact with the outer side of each guide rail s via an attachment member g, with the longitudinal direction being along the conveyance direction W and facing the side surface of the container t. ing.

  As shown in FIG. 2, the attachment plate 2 of the container stopper 1 is formed in a rectangular flat plate shape, and an opening 2 a penetrating through a flat portion facing the side surface of the container t is formed. The opening 2a is formed so that the length in the short direction is approximately half the length in the short direction of the mounting plate 2, and both ends in the longitudinal direction of the opening 2a are short in the opening 2a. It is formed in a semicircle having a diameter in the direction. At that time, the top of the semicircle in the longitudinal direction and the end of the mounting plate 2 are formed to have the same length as the radius of the semicircle. In addition, on the back surface side of the mounting plate 2, a plurality of screw holes 2b (28 in the figure) are formed around the outer edge of the opening 2a at equal intervals.

  A substrate 3 is laminated on the back side of the mounting plate 2. The substrate 3 is formed in a flat plate shape, a circular through hole 3c is formed in the center of the surface facing the mounting plate 2, and compressed air F is supplied to the opposite side of the surface facing the mounting plate 2. The introduction pipe 3a is screwed into the through-hole 3c, and a plurality of counterbore holes 3b (in the drawing, through which the bolts p are inserted at the same positions as the centers of the screw holes 2b formed in the mounting plate 2). 28) are drilled.

  As shown in FIG. 3, the diaphragm 4 disposed in the opening 2a of the mounting plate 2 has a convex protrusion 4c extending in the longitudinal direction of the rectangular natural rubber sheet. A semicircle whose diameter is the length in the short direction of the projecting portion 4c, and is formed integrally with the length in which the opening 2a of the mounting plate 2 is loosely inserted into the width in the direction. And is inserted loosely with the semicircle formed at the end of the opening 2a of the mounting plate 2.

  Further, the outer peripheral edge 4a of the diaphragm 4 is provided with mounting holes 4b through which the bolts p are inserted when the outer peripheral edge 4a is sandwiched between the mounting plate 2 and the substrate 3, respectively. A plurality (28 in the figure) are formed at the same position as the center.

  Further, a plurality of protrusions 5 protruding in the shape of the same shape on the surface of the top of the protruding protrusion 4c extending in the longitudinal direction of the diaphragm 4 are spaced over the entire length (in the figure, 29). Further, the two-side intersecting portion 5a of the letter-shaped protrusion 5 is formed in the same longitudinal direction, and the letter-shaped protrusion 5 is located at the center of the diaphragm 4 in the transport direction W. The protruding portion 5 is formed to have a thickness larger than that of the square-shaped protruding portion 5 positioned at the upstream and downstream ends in the transport direction W.

  As shown in FIG. 2, the container stopper 1 has a projection 4 c of the diaphragm 4 disposed in the opening 2 a of the mounting plate 2, and the substrate 3 is placed on the back side of the mounting plate 2. The provided introduction pipes 3a are laminated outward, and bolts p are inserted into the counterbore holes 3b formed in the substrate 3, so that the screw holes 2b formed in the mounting plate 2 are respectively It is configured to be screwed.

  In order to stop the container t conveyed by air conveyance on the conveyance line k using the container stopper 1 having the above configuration, first, as shown in FIG. 1, the longitudinal direction of the container stopper 1 is set to the conveyance line k. The diaphragm 4 is attached to a position where the diaphragm 4 can move forward and backward with respect to the side surface of the container t.

  Next, the container t is transported and operated on the transport line k by air transport. At that time, if a trouble such as a shortage of the container t occurs on the upstream side of the transport line k or the container t becomes full on the downstream side, the substrate on the opposite side of the transport line k of the container stopper 1. Compressed air F is supplied from the introduction pipe 3 a formed in 3.

  The supplied compressed air F is sent to the diaphragm 4 sandwiched between the mounting plate 2 and the substrate 3, and when the internal pressure in the diaphragm 4 becomes higher than the external pressure, the opening 2 a of the mounting plate 2. As a result, the diaphragm 4 expands toward the transport line k.

  At this time, the container t is pushed out from the end portion of the expanding diaphragm 4 to the guide rail s on the opposite side of the diaphragm 4 while coming into contact with the thin-shaped projection 5 having a small thickness, while reducing the speed. , It proceeds to the narrowest part of the central part of the diaphragm 4.

  And in the center part of the diaphragm 4, it is pinched | interposed between the guide rail s and the square-shaped projection part 5 of the diaphragm 4, and stops. At this time, even when moisture m such as water droplets adheres to the container t, the water is removed between the side surface of the container t and the surface of the diaphragm 4 by the drainage action of the rectangular protrusion 5. Since generation of the thin film r due to m does not occur, it can be surely stopped (see FIG. 4).

  In addition, when the problem related to the transfer line k is solved and the transfer line k is operated again, the compressed air is extracted from the introduction pipe 3a of the substrate 3, so that the internal force in the diaphragm 4 is reduced to the external pressure. Diaphragm 4 is restored. And the container t conveyed by air conveyance is conveyed again along the conveyance direction W along the conveyance line k.

  According to the container stopper of the above-described embodiment, the container stopper 1 includes a flat mounting plate 2 in which openings 2a penetrating both surfaces are formed, and a substrate 3 laminated on the back side of the mounting plate 2, The diaphragm 4 is provided in the opening 2 a of the mounting plate 2 and the outer peripheral edge 4 a is sandwiched between the mounting plate 2 and the substrate 3. The substrate 3 is supplied with compressed air F to the diaphragm 4. It has a structure in which an introduction pipe 3a is formed. Therefore, the number of parts constituting the container stopper 1 is small, and even when used for a long time, the degree of failure is small. In addition, even when a failure or damage occurs during long-term use, the cause can be identified and the parts can be replaced smoothly, and the manufacturing cost and running cost can be suppressed.

  Further, since the diaphragm 4 is provided so as to be able to advance and retreat with respect to the side surface of the container t, by supplying compressed air F from the introduction pipe 3a provided on the substrate 3, the width of the conveyance portion of the conveyance line k is increased. It can be narrowed easily. Therefore, even when a sudden trouble occurs, the diaphragm 4 can be instantaneously expanded to stop the container t, and when the trouble is solved and the transport line k is operated again, the inside of the diaphragm 4 By pulling out the compressed air, the narrowed width of the transport unit can be instantaneously restored.

  Furthermore, since the two-side intersecting portion 5a of the protruding portion 5 protruding like a letter is located on the surface of the diaphragm 4 so as to be located upstream with respect to the transport direction W of the transport line k, When the container t is temporarily stopped due to some trouble, even if the water m such as a water droplet adheres to the side surface of the container t, the two-side intersecting portion 5a of the rectangular protrusion 5 is gradually reduced. Since the portion sequentially contacts the side surface of the container t, the water m can be drained efficiently, and the contact area with the side surface of the container can be reduced by forming the square-shaped protrusion 5. be able to. Accordingly, it is possible to prevent the generation of the thin film r that is caused when the moisture m is drawn between the side surface of the container t and the surface of the diaphragm 4, and reliably the container t without reducing the friction coefficient of the contact surface. Therefore, it is not necessary to install a plurality of container stoppers 1.

  Then, by forming a plurality of letter-shaped protrusions 5 in the longitudinal direction of the diaphragm 4 at intervals, the container t to be conveyed by air is narrowed by the expansion of the diaphragm 4. Thus, when temporarily stopping the flow of the container t, since any one of the protrusions 5 captures the side surface of the container t regardless of the position of the container t, the stopping accuracy can be improved. .

  In addition, the plurality of protrusions 5 having a letter-shaped shape are formed on the protrusions 5 positioned at the center of the conveyance direction W rather than the protrusions 5 positioned at the upstream and downstream ends of the diaphragm 4 in the conveyance direction W. By increasing the thickness dimension, the end of the diaphragm 4 in the transport direction W in the process until the container t transported in the transport direction W stops at the center of the diaphragm 4 due to expansion of the diaphragm 4. Since the contact is made in order from the thin-shaped projection 5 having a small thickness to the central portion where the width of the transport line k is narrowest without being caught by the square-shaped projection 5 formed in the vicinity, The conveyance speed of the container t can be reduced. Therefore, even when the container t is forcibly stopped on the transport line k, the container t can be prevented from overturning, and the pressure of the compressed air F supplied to the diaphragm 4 can be increased and pressed. There is no need to raise it, and the container t can be stopped reliably.

  Then, by forming the diaphragm 4 from soft natural rubber, when supplying the compressed air F from the introduction pipe 3a provided on the substrate 3, the diaphragm 4 can be instantaneously supplied without supplying high-compressed air. The container t can be stopped by being inflated, and when the compressed air F is extracted, the diaphragm 4 can be instantaneously returned to the original, so that the working efficiency can be improved.

  Further, by forming the diaphragm 4 from soft natural rubber, when the diaphragm 4 is expanded and brought into contact with the side surface of the container t, the side surface of the container t is not damaged by dents or scratches, The container t can be stopped.

  In the above-described embodiment, only the case where the protrusion 5 protruding in a letter shape is used on the surface of the diaphragm 4 is described. However, the present invention is not limited to this. For example, the protrusion 4 protrudes in a letter W shape. This can be dealt with by using a protrusion. In that case, each two-side crossing portion of the protruding portion protruding in a W shape is formed on the upstream side in the transport direction W.
