Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a carrier that continuously conveys a large number of bottles in a bottle processing apparatus such as a bottle washer, and in particular, a bottle holder that contains and holds bottles is attached to an attached body (bridge) that constitutes the carrier. It is related with the attachment structure of the bottle holder of the bottle washer attached to.
[0002]
[Prior art]
In a bottle processing apparatus such as a washing machine, washing and the like are performed while a number of bottles are held and continuously conveyed by a carrier that circulates and runs in the apparatus. The carrier is usually connected to endless chains on both sides arranged in parallel with a large number of bridges extending in a direction perpendicular to the chains, and holder mounting holes are formed at predetermined intervals in each of the bridges. And it has the structure which inserted and fixed the holder in each holder attachment hole, accommodates one bottle in each bottle holder in the inverted state, and conveys the inside of the said bottle processing apparatus.
[0003]
The bottle holder must store the bottle in an inverted state, hold it in a stable posture, and transport it. Therefore, it is necessary to use a bottle with the optimum size and shape according to the size and shape of the bottle to be held. is there. Therefore, the bottle holder is replaced and used according to the shape of the bottle to be processed.
[0004]
Therefore, the bottle holder should be easily attached to and detached from the bridge, and after being attached, the bottle holder must be firmly connected without play so that the bottle can be stably conveyed. As a mounting structure of such a bottle holder to the bridge, conventionally, a flange having a connecting hole such as a rivet hole is formed on the outer surface of the cylindrical bottle holder, and the bottle holder is inserted into the holder mounting hole of the bridge. Then, the connecting hole of the rivet or the like formed on the flange and the position of the connecting hole by the rivet or the like formed around the holder mounting hole of the bridge are matched and fixed with a rivet or a screw. (See Fig. 1 of 60-30233, Fig. 9 and Fig. 11 of Utility Model Registration No. 2510412, etc.).
[0005]
In the structure in which the bottle holder is fixed to the bridge with rivets or screws as described above, there is a problem that the replacement work is very troublesome and takes time. In view of this, an attachment structure in which the bottle holder can be attached and detached with one touch has been proposed (Japanese Utility Model Publication No. 60-30233, Utility Model Registration No. 2510412).
[0006]
As shown in FIGS. 10 (a) and 10 (b), the mounting structure described in the utility model registration No. 2510412 has a carrier frame at the bottom of the flange B of the bottle cage A (corresponding to the bottle holder of the present invention). C (corresponding to the bridge of the present invention) separated by a plate thickness D (as described in the above publication, it is actually separated from the plate thickness D as described later) A protrusion E that is inclined up to the body part is formed at the top, and a notch F having a substantially inverted U shape is provided on three sides around the protrusion E. When installing the bottle cage A, when the bottle cage A is inserted into the carrier frame C, the protruding portion E is deformed to the inner side of the bottle cage A (see FIG. 10B). When the apex passes through the carrier frame C, the protrusion E returns to its original position due to elasticity, and the carrier frame C is sandwiched and fixed between the flange B and the protrusion E.
[0007]
Further, in the mounting structure described in Japanese Utility Model Publication No. 60-30233, as shown in FIGS. 11A and 11B, a locking groove H is provided on the side of the heel support G. The locking groove H has a chevron with a slightly inclined slope in the axial direction that protrudes slightly from the other part of the side of the heel support G, and a locking groove J is formed in the lateral direction at a portion corresponding to the peak of the chevron. ing. In order to increase the elasticity of the locking groove H, a slit K parallel to the axial direction of the bottle supporter G is formed. When the heel support G is attached to the bridge L, it is inserted into the hole N of the top plate M of the bridge L. When the lower slope of the locking groove H is pressed against the periphery of the hole N along with the insertion, the locking groove H bends inward. When the locking groove J reaches the position of the top plate M, the locking groove portion H is released from the pressing force and restored outward, the locking groove J fits in the periphery of the hole N, and the heel support G is bridged. The vertical movement is restricted with respect to L.
[0008]
[Problems to be solved by the invention]
When the bottle cage A is inserted into the mounting hole of the carrier frame C with the configuration of the first publication (utility model registration No. 2510412), as shown in FIG. Since E is pushed around the hole in the carrier frame C and deformed to the inside of the bottle cage A, the vertical groove width Fb (see FIG. 10B) of the notch F is the free groove width. It becomes narrower than Fa (see FIG. 10A). In order for the carrier frame C to fit into the narrowed cutout groove F, the vertical width Fa of the cutout groove F must be larger than the plate thickness D of the carrier frame. If the vertical width Fa of the cutout groove F is made larger than the thickness D of the carrier frame in this way, in the state where the carrier frame C is fitted in the cutout groove F, there is a backlash in the vertical direction between the two. It will occur. As described above, if there is a backlash between the carrier frame C and the bottle cage A attached to the carrier frame C, the bottle may be misaligned during conveyance, which may hinder the processing process. was there. In addition, there is a problem that the strength is reduced when the width of the notched groove is large.
[0009]
Further, even in the configuration described in the second publication (Japanese Utility Model Publication No. 60-30233), the heel support G is inserted into the hole N of the top plate M of the bridge L as shown in FIG. Then, the locking groove H is pushed into the top plate M of the bridge L and is deformed to the inner side of the saddle support G, and the width of the locking groove J becomes narrower than the free state. Therefore, the width of the locking groove J must be made significantly wider than the thickness of the bridge L. For this reason, there is a problem that play occurs between the attached saddle support G and the bridge L, and the accuracy of the bottle position is impaired.
[0010]
The present invention has been made to eliminate the above-mentioned drawbacks, and the inner peripheral edge of the bridge holder mounting hole is inserted into a groove having a width substantially the same as the plate thickness of the portion where the bridge holder mounting hole is provided. It is an object of the present invention to provide a bottle holder mounting structure in which a bottle holder can be mounted on a bridge without any backlash and can be mounted by an extremely simple operation.
[0011]
[Means for Solving the Problems]
The bottle holder mounting structure of the bottle washer according to the present invention is configured such that a cylindrical bottle holder that accommodates a bottle in an inverted state is inserted into a plurality of holes formed at equal intervals in the mounted body. A notch groove having a vertical groove and a horizontal groove on the peripheral wall of the bottle holder, a flange spaced above the horizontal groove by a predetermined distance, and a guide portion below the flange, And a projecting portion that gradually protrudes outward from the lower side toward the upper side is formed below the lateral groove, and when the projecting portion is pressed, the projecting portion becomes circumferential. The longitudinal groove and the lateral groove are arranged so as to be elastically deformed toward the inner surface, and the inner peripheral edge of the hole of the mounted body is fitted between the lower surface of the flange and the upper surface of the protruding portion. The inner surface is brought into contact with the guide portion .
[0012]
The mounting structure of the bottle holder washing bottle machine according to prior Symbol onset bright, inserting a bottle holder in the bore of the mounting member, the elastic deformation inner circumferential edge of the hole presses the protrusion to the inner side of the bottle holder However, since the projecting portion is deformed so as to rotate in the circumferential direction, even in the deformed state, the interval between the portions where the inner peripheral edge of the hole of the attached body is fitted is not narrowed. Accordingly, it is not necessary to enlarge the vertical width of the lateral groove, so that the play after the bottle holder is attached to the mounted body can be eliminated, and the strength of the bottle holder can be prevented from being lowered. be able to. Further, since the inner surface of the hole of the mounted body comes into contact with the guide portion, the entire circumference of the bottle holder is supported by the mounted body and its deformation is prevented.
[0015]
DETAILED DESCRIPTION OF THE INVENTION
The present invention will be described below with reference to embodiments shown in the drawings. FIGS. 1 to 6 are views showing an example of a bottle holder applied to a bottle holder mounting structure of a bottle washer according to an embodiment of the present invention, and FIGS. 7 to 9 are mounting targets to which the bottle holder is mounted. It is a figure which shows an example of a body (bridge). First, the configuration of the bottle holder 2 will be described. The bottle holder 2 has a cylindrical shape, the upper part 4 (the part in which the bottle body is accommodated) has a large diameter, and the lower part 6 is slightly tapered toward the tip side. A plurality of (four in this embodiment) ribs 8 are radially formed on the inner surface of the lower portion 6 at equal intervals, and the shoulder portion of the bottle inserted into the bottle holder 2 in an inverted state is provided. , Supported by these ribs 8.
[0016]
A flange 10 is formed on the outer peripheral surface of the upper portion 4 of the bottle holder 2 over the entire circumference. Furthermore, the rectangular expansion part 10a with which an end surface is parallel is formed in two right and left places of this flange 10 (refer FIG. 2). The enlarged portions 10a of the flanges 10 are in contact with the enlarged portions 10a of the adjacent bottle holders 2 when the large number of bottle holders 2 are arranged and attached to the bridge 20, and serve to prevent rotation. Below the flange 10, an inverted L-shaped notch groove 16 including a lateral groove 12 and a longitudinal groove 14 is formed. Two sets of the notch grooves 16 are provided at symmetrical positions with a pair of the lateral grooves 12 facing in opposite directions. As shown in an enlarged view in FIG. 5, the lateral groove 12 is formed at a position slightly away from the lower surface 10 b of the flange 10, and a portion immediately below the flange 10 is a bridge 20 as will be described later. It becomes the guide part 18 at the time of attaching to. The lower surface of the guide portion 18 is an inclined surface whose inner surface extends downward.
[0017]
A tapered protrusion 22 is formed adjacent to the longitudinal groove 14 constituting each notch groove 16. The tapered protrusion 22 is highest on the lateral groove 12 side, that is, on the upper side, and gradually lowers as it goes downward, and its lower end coincides with the outer surface of the cylindrical upper part 4 (see FIG. 3). The distance d between the upper end surface 22a of the projecting portion 22 and the lower surface 10a of the flange 10 substantially matches the plate thickness t (see FIG. 8) of the mounting surface 24 of the bridge 20 described later.
[0018]
On the other hand, the bridge 20 has a shape obtained by bending a plate body into a U-shaped cross section, and a plurality of holder mounting holes 24a for inserting the bottle holder 2 are formed at equal intervals on the upper mounting surface 24. . The inner diameters of these holder mounting holes 24a substantially coincide with the outer diameter of the upper portion 4 of the bottle holder 2. Further, the lower portions 26a, 28a side of the side walls 26, 28 are bent slightly inward. Both ends in the longitudinal direction of the bridge 20 are connected to an endless chain 30 wound around a plurality of sprockets arranged in a bottle processing device such as a bottle washer, and these chains 30 are connected to the chains 30 as the sprocket rotates. The attached roller 32 travels while being supported by a rail 34, and circulates in the bottle processing apparatus.
[0019]
When attaching the bottle holder 2 to the bridge 20, the bottle holder 2 is inserted into the holder attachment hole 24 a of the bridge 20 from the small diameter portion 6 side of the tip of the bottle holder 2. When the bottle holder 2 is inserted and the lower side of the protruding portion 22 hits the inner surface of the holder mounting hole 24a, the protruding portion 22 protrudes greatly outward and gradually upwards, so that the bottle holder 2 faces downward. As pushed down, the protrusion 22 is pushed by the inner surface of the mounting hole 24 a and elastically deforms toward the inner side of the bottle holder 2. At this time, as shown in FIGS. 10B and 12C, the protrusion of the conventional bottle holder is pushed in the axial direction (the direction of the axis of the bottle inserted into the bottle holder). As a result, the width of the notch groove is significantly reduced. On the other hand, in the present embodiment, the notch groove 16 is L-shaped consisting of the lateral groove 12 and the longitudinal groove 14, so that it not only deforms in the axial direction but also rotates in the circumferential direction. And pushed. For this reason, the width (vertical width) of the lateral groove 12 is not greatly reduced as in the conventional configuration. Therefore, the vertical width of the portion where the inner periphery of the mounting hole 24a of the bridge 20 is fitted, that is, this In the embodiment, although the distance d between the lower surface 10b of the flange 10 and the lower side of the lateral groove 12 (the upper end surface 22a of the protrusion 22) is substantially equal to the plate thickness t of the bridge 20, the bridge 20 is attached. The part 24 can be fitted.
[0020]
When the tapered protrusion 22 formed on the outer surface of the bottle holder 2 is pressed against the inner surface of the mounting hole 24a, the protrusion 22 is moved in the vertical direction when the bottle holder 2 is elastically deformed inward. Therefore, the amount of deformation in the axial direction is smaller than in the prior art. Therefore, the distance d between the portions where the mounting surface 24 of the bridge 20 is fitted can be made smaller than that of the conventional configuration, and the backlash after mounting can be reduced. Moreover, as an attaching operation, it is only necessary to insert the bottle holder 2 into the attaching hole 24a of the bridge 20 from the small diameter portion 6 side at the lower end thereof, which is extremely simple. Further, in the embodiment, since the guide portion 18 is formed in the lower portion of the flange 10, the inner peripheral surface of the mounting hole 24 a of the bridge 20 fitted between the lower surface 10 b of the flange 10 and the upper surface 22 a of the protruding portion 22. However, it abuts over the entire circumference of the bottle holder 2. Therefore, since the bottle holder 2 is reinforced by the attachment portion 24 of the bridge 20 having high rigidity, it is possible to prevent the bottle holder 2 from being deformed by the action of an external force.
[0021]
In the above-described embodiment, the notch groove 16 including the lateral groove 12 and the longitudinal groove 14 is formed on the outer wall of the bottle holder 2, and the tapered protrusion 22 provided adjacent to the notch groove 16 is formed. Since the protrusion 22 is elastically deformed toward the inner side of the bottle holder 2 by being pressed by the inner peripheral surface of the mounting hole 24a of the bridge 20, the protrusion 22 has an axial direction (vertical direction) and a circular shape. Deformation in both circumferential (lateral) directions. In such a configuration, since the amount of deformation in the axial direction is significantly smaller than in the conventional configuration, the mounting surface 24 of the bridge 20 can be fitted without increasing the vertical width of the lateral groove 12. However, if the deformation of the protrusion 22 in the axial direction is completely eliminated and the protrusion 22 is deformed only in the lateral direction (circumferential direction), the backlash when the bottle holder 2 is attached to the bridge 20 is reduced. It can be further reduced.
[0022]
FIG. 12 shows another example of the bottle holder 102. Below the flange 110, two parallel lateral grooves 112, 113 and a short intermediate between these two lateral grooves 112, 113 are shown. A vertical groove 114 is formed. An intermediate portion between the two upper and lower lateral grooves 112 and 113 is a protruding portion 122 having an inclination that gradually protrudes outward from the lower side toward the upper side. When the bottle holder 102 having this configuration is inserted into the mounting hole 24a of the bridge 20 (see FIG. 8) similar to the above embodiment, the protruding portion 122 is deformed only in the circumferential direction around the longitudinal groove 114. When the protrusion 122 is deformed, the upper and lower widths of the upper lateral groove 112 into which the mounting plate 24 of the bridge 20 is inserted are not reduced, so that the groove width is the same as the plate thickness t of the mounting portion 24 of the bridge 20. The bottle holder 102 can be attached without any play.
[0023]
FIG. 13 shows still another embodiment. In the bottle holder 202, a U-shaped notch groove 216 is formed in the lower portion of the flange 210, and a portion surrounded by the notch groove 216 is formed from the lower side. The protrusion 222 has an inclination that gradually protrudes outward toward the upper side. When the bottle holder 202 having this configuration is also inserted into the mounting hole 24a of the bridge 20, the protrusion 222 is deformed only in the circumferential direction, so that the width of the groove 212 on the upper side of the U-shaped notch groove 216 is increased. What is necessary is just to make it the same magnitude | size with the board thickness t of the bridge | bridging 20, and it can attach in a state without backlash at all.
[0024]
The configuration of the bottle holder applied to the mounting structure of the bottle holder according to the present invention is not limited to the notch groove having the shape as shown in the figure, and the protruding portion is not only deformed in the axial direction but also the circumference. Any material that can be deformed in the direction (lateral direction) may be used. Thus, if it can be deformed in the circumferential direction as well, the width of the groove into which the bridge is fitted can be made narrower than before, and it goes without saying that the above-described effects can be obtained. In each of the above embodiments, the shape of the bottle holder is cylindrical in order to convey and process the round bottle, but when processing a deformed bottle such as a square bottle or an elliptical bottle, According to the shape of the bottle, the shape may be a square or an ellipse, and the notch groove as described above may be formed.
[0025]
