  The interval between the side walls a1 and a2 guiding the one end and the other end of the workpiece W in the vertical pipe a is such that the direction of the end face W2 of the workpiece W changes from one side wall a1 side to the other side wall a2 side. It is narrowed so that there is no gap. As a result, the workpiece W is conveyed to the capping machine while the direction of the end face W2 is always maintained in a constant direction, and is thus automatically attached to the bottle mouth by the capping machine.

  However, in the conventional air transfer device, one end or the other end of the work W comes into contact with one or the other wall portions a1 and a2 of the vertical pipe a during the transfer of the work W. This is due to the phenomenon that the workpiece W has a characteristic that the end face W2 that is closed as the aerodynamic characteristic due to the shape of the work W tends to be stabilized in the downward direction and the open end is in the upward direction. For this reason, when the corner | angular part of the front end side of the conveyance direction in the workpiece | work W contacts one or the other side wall a1, a2 of the vertical pipe | tube a, the said corner | angular part bites into one or the other side wall a1, a2. Since the rotational force acts, there is a problem that the workpiece W is easily damaged and the vertical pipe a is also easily damaged.

Is disposed at a position along the lower end portion of the substrate member, and the other end portion is disposed at a position above the conveyance plate in the low position conveyance path, so that the direction from the direction along the vertical conveyance path The length gradually changes in the direction along the low-position conveyance path. A plurality of air ejection holes configured to draw about ¼ circle in the direction and obliquely eject air toward the one direction of the conveying direction and drive the workpiece in the one direction. The high part board member is formed so as to gradually turn downward while protruding upward from a position along the upper end part of the board member by continuously curving in a semicircular shape in the width direction. And a first high substrate member having a plurality of air ejection holes for obliquely ejecting air toward the one direction of the conveying direction and driving the workpiece in the one direction, and continuous in the plate surface direction. One end of the bending direction is disposed at a position along the lower end of the first high substrate member, and the other end is positioned above the conveyance plate in the high position conveyance path. By disposing, the first high part substrate member It is configured to gradually change from the direction along the lower end of the sheet to the direction along the high-position conveyance path, and draws about 1/4 circle in the longitudinal direction, and the air is inclined toward the one direction of the conveyance direction. And a second high part substrate member having a plurality of air ejection holes for driving the workpiece in the one direction, and the low part support member faces the low part substrate member. And one end of the bending direction is arranged at a position along the lower end of the support member, and the other end is arranged at a position along the conveyance plate in the low position conveyance path. Thus, the workpiece is configured to be movably supported in the transport direction, and the high support member is continuously curved so as to face the high substrate member, and the bending direction thereof.

The high side member is arranged on the left and right between the high substrate member and the high support member so as to guide the work in the transport direction, and the high support member. It is characterized by being arranged at intervals with respect to .

According to a second aspect of the present invention, in the invention according to the first aspect, the support member, the low-part support member, and the high-part support member each have a width smaller than the diameter of the outer peripheral surface of the cylindrical portion of the workpiece. The side member, the low side member, and the high side member are formed from the support member, the low support member, or the high support member, respectively, from the substrate member, the low substrate member, or the upper substrate member. Are arranged at a certain interval on the side, and the dimension between the inner surfaces is formed to be larger than the diameter of the outer peripheral surface of the cylindrical portion, so that the supporting member, the low supporting member or the high supporting member And a row of workpieces are provided between the inner surfaces so as to be transportable .

According to a third aspect of the present invention, in the invention according to the second aspect , the support member, the low-part support member, and the high-part support member are perforated flat plates or a pair of strip-like plates arranged in parallel to each other. It is characterized by that.

  According to invention of Claims 1-3, a workpiece | work is conveyed upwards or downwards in a vertical direction conveyance path by the air which injects diagonally in one direction of a conveyance direction from the several air ejection hole in a board | substrate member. Can do.

  That is, when one direction of the conveyance direction in the vertical conveyance path is upward, the workpiece can be sequentially conveyed upward while abutting the support member by the air ejected obliquely upward from each air ejection hole. it can.

  In this case, the air ejected from each air ejection hole flows out of the longitudinal conveyance path through the gap between the support member and each side member. For this reason, since the flow of the air which raises continuously in the vertical direction conveyance path does not arise, it can prevent that the rotational force which the corner | angular part of a workpiece | work bites into a support member acts on the said workpiece | work. .

  Further, when one direction of the transport direction in the vertical transport path is downward, the work can be sequentially transported downward while the work is brought into contact with the support member by the air ejected obliquely downward from each air ejection hole. it can.

  Also in this case, since the air ejected from each air ejection hole does not flow downward continuously in the longitudinal conveyance path, the rotational force that the corner of the work bites into the support member acts on the work. Can be prevented.

  Therefore, it is possible to prevent the workpiece from being damaged regardless of whether the one direction of the conveyance is upward or downward. In addition, since the work constantly comes into contact with the support member, it is possible to prevent the support member from being damaged by the work. For this reason, the longitudinal conveyance path can be maintained in a clean state for a long time. It is extremely advantageous from the viewpoint of hygiene management to maintain the vertical conveyance path in a clean state.

Further , the work is transported from the low-position transport path side to the vertical transport path side or from the vertical transport path side to the low-position transport path side by air that is obliquely ejected in one direction from the plurality of air ejection holes in the lower substrate member. be able to.

  That is, when one direction of the conveying direction in the vertical direction conveying path is upward, the workpiece is lowered by the air jetted obliquely in one direction of the conveying direction from each air ejection hole of the lower substrate member. Can be conveyed from the low-position conveyance path side to the vertical conveyance path side.

  In this case, the air ejected from each air ejection hole flows out of the low direction changing conveyance path through between the low support member and each low side member. For this reason, there is no flow of air continuously moving in one direction in the conveyance direction in the low direction conversion conveyance path, so that the rotational force that the corner of the work bites into the low part support member is generated. Can be prevented.

  Further, when one direction of the conveying direction in the vertical direction conveying path is downward, the workpiece is lowered by the air jetted obliquely in one direction of the conveying direction from each air ejection hole of the lower substrate member. Can be conveyed from the longitudinal conveyance path side to the low position conveyance path side.

  Also in this case, the air ejected from each air ejection hole does not become a flow that continuously moves in one direction of the transport direction in the lower direction conversion transport path, so the corner portion of the workpiece becomes the lower support member. It is possible to prevent a rotational force that bites into the workpiece.

  In addition, since the moving direction of the workpiece gradually changes in the lower direction conversion conveyance path, a centrifugal force acts on the workpiece. This centrifugal force acts in a direction in which the workpiece is brought into contact with the lower portion supporting member. Therefore, it is possible to prevent the workpiece from floating from the lower support member and, for example, the corner portion of the workpiece from hitting the lower substrate member.

  Therefore, it is possible to prevent the workpiece from being damaged regardless of whether the direction of conveyance in the lower direction conversion conveyance path is the upper or lower direction, and the low direction conversion conveyance path can be cleaned for a long period of time. Can be maintained in a stable state.

Furthermore , the work is transported from the vertical transport path side to the high position transport path side or from the high position transport path side to the vertical transport path side by the air jetted obliquely in one direction of the transport direction from the plurality of air ejection holes in the high substrate member. be able to.

  That is, when one direction of the transport direction in the vertical transport path is upward, the transport direction from each air ejection hole of the high substrate member including the first high substrate member and the second high substrate member. With the air jetted obliquely in one direction, the workpiece can be conveyed from the vertical conveyance path side to the high position conveyance path side while being brought into contact with the high portion support member.

  In this case, the air ejected from each air ejection hole flows out of the high direction changing conveyance path through between the high portion supporting member and each high side member. For this reason, there is no flow of air that continuously moves in one direction in the conveyance direction in the high direction conversion conveyance path, so that the rotational force in the direction in which the corners of the work bite into the high part support member is affected. Can be prevented.

  Further, when one direction of the transport direction in the vertical transport path is downward, the transport direction from each air ejection hole of the high substrate member composed of the first high substrate member and the second high substrate member With the air jetted obliquely in one direction, the work can be conveyed from the high position conveyance path to the vertical direction conveyance path while abutting the work against the high part support member.

  Also in this case, the air ejected from each air ejection hole does not become a flow that continuously moves in one direction of the conveyance direction in the high direction conversion conveyance path, so that the corner portion of the workpiece becomes the high portion support member. It is possible to prevent a rotational force that bites into the workpiece.

  In addition, since the moving direction of the workpiece gradually changes in the section where the first high substrate member exists, a centrifugal force acts on the workpiece. This centrifugal force acts on one of the high side members. It will act in the direction of contact. Furthermore, since the moving direction of the workpiece gradually changes even in the section where the second high substrate member exists, the centrifugal force acts on the workpiece. This centrifugal force abuts the workpiece on the high support member. It will act in the direction to make it. For this reason, it can prevent that a workpiece | work floats from a high part support member with a centrifugal force, for example, and the corner | angular part of the said workpiece | work contacts a high part board | substrate member.

  Therefore, it is possible to prevent the workpiece from being damaged regardless of whether the direction of conveyance in the high direction conversion conveyance path is the upper or lower direction, and the high direction conversion conveyance path can be cleaned for a long period of time. Can be maintained in a stable state.

Is arranged. Thus, the second high substrate member 55 is configured to gradually change from a substantially vertical direction along the lower end portion of the first high substrate member 54 to a substantially horizontal direction along the high position conveyance path 2. .

  The high substrate member 51 including the first high substrate member 54 and the second high substrate member 55 constitutes one closed surface of the plenum chamber 5 a as with the substrate member 31.

A plurality of air ejection holes 51a are formed. The air ejection holes 51 a extend continuously from the line in which the air ejection holes 31 a are arranged, and are arranged on the substantially center line in the width direction of the high-part substrate member 51 at a constant interval.

The upper end of the support member 32 is continuously connected, and the other end is disposed at a position along the transport plate 21 of the high position transport path 2. In this case, the high support member 52 is installed so that the other end thereof is in contact with the side edge of the transport plate 21 from the lateral direction (a direction orthogonal to the transport direction of the transport plate 21). The inner surface of the section is set so as to be flush with the upper surface of the transport plate 21 or slightly higher than the upper surface.

  The high portion support member 52 is formed to have the same width as the support member 32 and is formed continuously from the support member 32. The interval between the high substrate member 51 and the high support member 52 is set to be the same as the interval between the substrate member 31 and the support member 32. Furthermore, the high part support member 52 is installed so that the center line of the width direction may correspond with the line where the air ejection holes 51a are arranged.

  The high side members 53 are arranged on the left and right between the high substrate member 51 and the high support member 52 so as to guide the workpiece W in the transport direction, and from the high support member 52 to the high substrate member. It is arranged at an interval on the 51 side. That is, each of the high side members 53 is formed by continuously curving a belt-like plate in a semicircular shape in the plate surface direction in a portion corresponding to the first high board member 54. The portion corresponding to the second high-part substrate member 55 is formed by continuously curving in a width of about 1/4 in the width direction, and one side edge is one of the high-part substrate members 51. The other side edge is arranged at a distance from the high part support member 52 to the high part substrate member 51 side while being fixed to the high part substrate member 51 in contact with the surface 51b.

  In addition, each of the high side members 53 is installed at a position that is equidistant on the left and right with respect to the line in which the air ejection holes 51a are arranged, and the dimension between the opposing inner surfaces is a cylindrical portion of the workpiece W. It is larger than the diameter of W1. In addition, the clearance gap between the high part support member 52 and each high part side member 53 is set so that it may become the same as the clearance gap between the support member 32 and each side member 33, and the workpiece | work W changes high part direction. It does not jump out of the conveyance path 5. In addition, each high portion side member 53 has one end portion continuously connected to the upper end portion of each side member 33 of the longitudinal conveyance path 3, and the other end portion being one guide plate of the high position conveyance path 2. It is installed so as to abut at a substantially right angle from the lateral direction. In addition, one guide plate 22 is notched so that the workpiece W can be moved between the pair of high portion side members 53.

  In the air conveyance device configured as described above, the plurality of air ejection holes 41a, 31a, 51a in each of the lower substrate member 41, the substrate member 31, and the higher substrate member 51 are obliquely inclined in one direction of the conveyance direction. The workpiece W supplied from the low position conveyance path 1 is conveyed to the high position conveyance path 2 via the low direction conversion conveyance path 4, the vertical direction conveyance path 3, and the high direction conversion conveyance path 5 by the jetted air. Can do.

  That is, the workpiece W supplied from the low position transport path 1 to the low direction conversion transport path 4 is end-faced by air jetted obliquely in one direction in the transport direction from each air ejection hole 41a of the low part substrate member 41. The portion W2 is conveyed to the vertical conveyance path 3 while being in contact with the lower portion support member 42.

  In this case, the air ejected from each air ejection hole 41a flows out of the low direction changing conveyance path 4 through the gap between the low portion supporting member 42 and each low side member 43. . For this reason, since the flow of the air which moves continuously in one direction in the conveyance direction in the low part direction conversion conveyance path 4 does not occur, the corner part of the end surface part W2 in the workpiece W bites into the low part support member 42. It is possible to prevent the rotational force in such a direction from acting on the workpiece W.

  In addition, since the moving direction of the workpiece W gradually changes in an arc shape in the lower direction conversion conveyance path 4, a centrifugal force acts on the workpiece W. This centrifugal force acts on the end surface portion W2 of the workpiece W. Since it acts in the direction to contact the low part support member 42, it is possible to prevent the corner of the work W from hitting the low part substrate member 41 by floating the work W from the low part support member 42. Can do.

  Therefore, it is possible to prevent the workpiece W from being damaged in the lower direction changing conveyance path 4. Further, since the workpiece W is in a state of being in constant contact with the lower portion support member 42, it is possible to prevent the lower portion support member 42 from being damaged from the workpiece W. For this reason, the low direction change conveyance path 4 can be maintained in a clean state over a long period of time. In addition, it is very advantageous also from hygiene management to maintain the low part direction conversion conveyance path 4 in a beautiful state.

  Next, the workpiece W supplied from the lower direction conversion conveyance path 4 to the vertical direction conveyance path 3 has its end face W2 abutted against the support member 32 by the air jetted obliquely upward from each air ejection hole 31a. As a result, the paper is sequentially conveyed upward.

  Also in this case, the air ejected from each air ejection hole 31a flows out of the vertical conveyance path 3 through between the support member 32 and each side member 33. For this reason, there is no flow of air that continuously rises in the vertical conveyance path 3, so that the rotational force in the direction in which the corner portion of the end surface portion W2 of the workpiece W bites into the support member 32 is affected. It can prevent acting on the workpiece W.

  Accordingly, it is possible to prevent the workpiece W from being damaged in the vertical conveyance path 3 and to maintain the vertical conveyance path 3 in a clean state for a long period of time.

  Next, the work W supplied from the vertical conveyance path 3 to the high part direction conversion conveyance path 5 has its end face W2 at a high part by the air jetted obliquely in one direction of the conveyance direction from each air ejection hole 51a. It is conveyed to the high position conveyance path 2 while being brought into contact with the support member 52.

  Also in this case, the air ejected from each air ejection hole 51 a flows out of the high direction changing conveyance path 5 through between the high portion supporting member 52 and each high portion side member 53. For this reason, since the flow of the air which moves continuously in one direction of the conveyance direction in the high portion direction conversion conveyance path 5 does not occur, the corner portion of the end surface portion W2 in the workpiece W bites into the high portion support member 52. It is possible to prevent the rotational force in such a direction from acting on the workpiece W.

  In addition, since the moving direction of the workpiece W gradually changes in an arc shape in the section where the first high substrate member 51 exists, a centrifugal force acts on the workpiece W. This centrifugal force is applied to the cylinder in the workpiece W. Since the outer peripheral surface of the portion W1 acts in the direction in which the outer peripheral surface of the portion W1 comes into contact with the inner surface of the one high portion side member 53, neither the workpiece W nor the high portion side member 53 is damaged. Furthermore, since the moving direction of the workpiece W gradually changes in an arc shape in the section where the second high-level substrate member 51 exists, a centrifugal force acts on the workpiece W. This centrifugal force is applied to the workpiece W. This acts in a direction in which the end surface portion W2 is brought into contact with the high portion support member 52. For this reason, it can prevent that the workpiece | work W floats from the high part support member 52 with a centrifugal force, and the corner | angular part of the said workpiece | work W hits the high part board | substrate member 51. FIG.

  Therefore, it is possible to prevent the workpiece W from being damaged in the high direction changing transfer path 5 and to maintain the high direction changing transfer path 5 in a clean state for a long period of time.

  In addition, the workpiece W with the end surface portion W2 facing downward in the low position conveyance path 1 passes through the low direction conversion conveyance path 4, the vertical direction conveyance path 3, and the high direction conversion conveyance path 5 to thereby move in the vertical direction. Without being changed, the sheet is supplied to the high-position conveyance path 2 with the end face W2 facing downward. Accordingly, the work W supplied to the high-position transport path 2 is transported to, for example, a capping machine while maintaining a certain posture with the end face W2 facing downward, and the bottle mouth can be closed without delay. Become.

  In the above embodiment, one direction of the transport direction is the direction from the low-position transport path 1 to the vertical transport path 3 in the low direction conversion transport path 4 and the upper direction in the vertical transport path 3. In the high direction changing transport path 5, the direction from the longitudinal transport path 3 to the high position transport path 2 is set, but the opposite direction may be set as one direction. However, in that case, air ejection holes 11a, 21a, 31a, 41a, 51a are provided in order to eject air obliquely in a direction opposite to the air ejection direction.

  However, in this case, by connecting the other end of the high position conveyance path 2 and the high direction changing conveyance path 5 in the same manner as the other position of the low position conveyance path and the low direction changing conveyance path 4. It is preferable that the work W can be continuously transported from the high position transport path 2 to the high direction changing transport path 5.

  Even when the air ejection holes 11a, 21a, 31a, 41a, 51a are provided in the reverse direction as described above, the corners of the work W bite into the high part support member 52, the support member 32, or the low part support member 42. The end surface W2 of the workpiece W is suspended from the high portion support member 52, the support member 32 or the low portion support member 42, and the corner portion of the workpiece W is the high portion substrate. It is possible to prevent the member 51, the board member 31 or the lower board member 41 from being hit. Therefore, it is possible to prevent the workpiece W, the high direction changing conveyance path 5, the vertical direction conveying path 3 and the low direction changing conveyance path 4 from being damaged.

  Further, as shown in FIG. 2B, the support member 32, the low part support member 42, and the high part support member 52 may be configured by a pair of belt-like plates 6 and 6 arranged in parallel to each other. Each of the belt-like plates 6 and 6 is configured such that one side edge of each of the belt-like plates 6 and 6 is installed at a certain interval with respect to the substrate member 31, the lower substrate member 41, and the higher substrate member 51. In addition, it is preferable to provide the low friction member 6a formed with resin with a small friction coefficient with respect to the workpiece | work W in the part along one side edge.

  When the support member 32, the low part support member 42, and the high part support member 52 are configured by the pair of belt-like plates 6, 6, the air ejected from the air ejection holes 31a, 41a, 51a is the side member 33, low Since it flows out to the outside from the gap between the part side member 43 and the high part side member 53 and the belt-like plate 6, it also flows out from between the belt-like plates 6 and 6 facing each other. W can be stably maintained in a state where W is brought into contact with one side edge of each belt-like plate 6 (or the low friction member 6a when the low friction member 6a is provided).

  Further, as shown in FIG. 2C, the support member 32, the low part support member 42, and the high part support member 52 are formed by a perforated flat plate (punching metal) 7 having a plurality of circular through holes. May be.

  Even when the support member 32, the low part support member 42, and the high part support member 52 are constituted by the perforated flat plate 7, the air ejected from the air ejection holes 31a, 41a, 51a is the side member 33, the low side member. 43 and the high-part side member 53 and the perforated flat plate 7 and the perforated flat plate 7 and the perforated flat plate 7. It can be stably maintained by contacting the low part support member 42 and the high part support member 52.

  Further, the support member 32, the low part support member 42 and the high part support member 52 are simply flat plates provided that a sufficient gap is provided between the support member 32, the low part support member 42 and the high part support member 52. You may comprise by.
