Description

  The present invention relates to a holder, and more particularly to a holder that is provided in a container washer and holds and conveys the container therein.

  Generally, a container washer is cleaned by immersing these containers in a cleaning tank or spraying cleaning water while the containers are continuously transported by a carrier to which a number of holders for holding the containers are attached. After that, the bottom surface of these containers accommodated in the holder is transported while being supported by the guide member, and the container is dropped from the holder and discharged at a position passing through the downstream end of the guide member. (For example, refer to Patent Document 1).

  The holder of a washing machine generally has a cylindrical main body portion that accommodates a container and a plurality of longitudinal ribs formed on the inner surface thereof (see, for example, Patent Document 2). Such a conventional holder will be described with reference to FIG. In FIG. 5A, two containers 10 are shown in the holder 118. However, in the container 10A that is entirely accommodated in the holder 118, the holder 118 is upside down from this figure, and the container 10A shows a state where 10A is inverted and held, and the container 10B in which the bottom portion 10Ba is pulled out from the holder 118 holds the mouth portion 10Bb side of the container 10B upward as shown in this figure. Indicates the state.

  The conventional holder 118 has one opening 136a (opening on the side where the mouth 10b of the container 10 is located when the container 10 is accommodated) of the cylindrical main body 136, and the bottom 10a of the container 10 opposite thereto. A plurality of ribs 138 are formed on the inner surface on the side of the small-diameter opening 136a on the side of the container mouth 10b. Only the vicinity of the opening 136a of these ribs 138 (the portion indicated by reference numeral 138a in FIG. 5) can support the mouth 10Ab when the container 10 is turned upside down (10A). Thus, it is enlarged toward the radially inward direction (see the right half of FIGS. 5A and 5B).

  A rib 138 having a low height is formed from the small-diameter opening 136a on the side where the container opening 10b is located to a position where the small-diameter opening 136a moves to the large-diameter portion 136c (FIG. 5A). And (refer to the left half of (b)), and the rib 138 is not formed on the large diameter portion 136c (see FIGS. 5A and 5C).

The conventional holder 118 is formed with ribs 138 for supporting the container 10 (10A) in an inverted state. However, the bottom holder 10Ba of the container 10B is supported while being supported by the guide member 22 as in discharging. In this case, the container 10B is slightly removed from the holder 136, and the mouth 10Bb side is inclined forward by friction with the guide member 22, so that the mouth 10Bb of the container 10B does not hit the rib 138 and is cylindrical. Directly hits the inner surface of the main body 136 (see the left side of FIG. 5B).
Japanese Examined Patent Publication No. 4-70069 (page 2-3, FIG. 1) Japanese Patent No. 3629585 (page 3-4, FIG. 2, FIG. 3)

  As described above, when the container 10B is inclined in the holder 118 and the opening 10Bb of the container 10B is in contact with the inner surface of the holder main body 136, the container 10B passes through the guide member 22 at the discharge position. When falling, there is a problem that the friction between the inner wall of the holder 118 and the opening 10Bb of the container 10B is large, and the timing at which the container 10B falls varies. Further, water contains magnesium and calcium. When hard water having a high content is used for cleaning, magnesium and calcium are deposited as a powdery scale. When this scale is deposited on the inner wall of the holder 118, there arises a problem that the frictional resistance is further increased and the container 10B is difficult to drop from the holder 118. Furthermore, since the mouth portion 10Bb of the container 10B falls while rubbing the inner wall of the holder 118, the scale accumulated on the inner wall of the holder 118 may adhere to the mouth portion 10Bb of the container 10B.

  Further, when the container opening 10Bb moves while being in contact with the inner wall of the holder 118 when the container 10B is discharged, there is a possibility that water droplets adhering to the inner wall of the holder 118 may be mixed into the container 10B. . Since the holder 118 and the container 10B are cleaned, water droplets adhering to the holder 118 and the container 10B themselves are not contaminated, but the bridge on which the holder 118 is supported is not cleaned and is attached to the bridge. The water that has fallen from the bridge may adhere to the inner wall of the holder 118, and it is not preferable that the water droplets enter the container 10B.

The present invention comprises a cylindrical main body part that is open at the top and bottom and covers the outer peripheral surface of the container, and a plurality of longitudinal ribs formed on the inner surface of the cylindrical main body part, and is installed in a washing machine. In the holder which is attached to the means and holds and conveys the container, the rib is formed over the entire length of the upper and lower sides of the cylindrical main body, and at least the interval between the ribs positioned in the front and rear in the carrying direction by the carrying means By making the diameter smaller than the diameter of the mouth of the container, the mouth of the container falling from the holder at the container discharge position is prevented from contacting the inner surface of the cylindrical main body.

  The holder of the present invention prevents the container from coming into direct contact with the inner surface of the holder when the container is discharged at the discharge position. Therefore, the contact area of the container with the holder is reduced, and friction is reduced. Since the container mouth does not directly contact the inner surface of the holder to which the scale is attached, the scale does not adhere to the mouth of the container, and water drops enter the container. There is no fear.

  The holder has a cylindrical main body portion that accommodates the container and a plurality of longitudinal ribs formed on the inner surface thereof. In particular, the interval between the ribs positioned in the front and rear of the holder in the conveying direction is set at the mouth of the container. The configuration of making the diameter narrower than the diameter achieves the object of making the container fall timing constant and preventing the container from becoming dirty.

  Hereinafter, the present invention will be described with reference to embodiments shown in the drawings. FIG. 1 is a cross-sectional view showing a main part of a cleaning machine provided with a holder according to an embodiment of the present invention, FIG. 2 is an enlarged view showing a container discharge part of the cleaning machine, and FIG. It is a figure to do. The washing machine of this embodiment is a multi-layer immersion type bottle washing machine (upstream is not shown), and a plurality of immersion tanks 6A and 6B partitioned by a plurality of partition walls 4A and 4B arranged in the can body 2. And a plurality of cleaning units 8A, 8B, and 8C that perform cleaning by spraying a cleaning liquid from the cleaning nozzles 8Aa, 8Ba, and 8Ca to the container 10, respectively. A large number of containers 10 are transported and washed by an endless carrier (conveying means) 12 wound around 6B.

  The immersion tanks 6A and 6B store caustic liquids having different concentrations and temperatures, wash the containers 10 by sequentially immersing the containers 10 conveyed by the carrier 12, and perform temperature control of these containers 10. Moreover, each washing | cleaning part 8A, 8B, 8C injects washing | cleaning liquid or water to the container 10 which slipped out from immersion tank 6A, 6B, and wash | cleans. In this Example, chemical | medical solution washing | cleaning of the upper part of immersion tank 6A is carried out. A chemical cleaning unit 8A including a nozzle 8Aa, a rinsing cleaning unit 8B including a rinsing cleaning nozzle 8Ba and a rinsing cleaning bath 8Bb, a finish cleaning nozzle 8Ca and a finishing cleaning tub 8Cb on the downstream side of the last immersion bath 6B. A finishing cleaning section 8C is disposed.

  Although the details of the endless carrier 12 are not shown, a pair of endless chains on both sides are wound around a large number of sprockets 14 (not shown except for the sprocket 14A of the discharge portion) arranged in the can 2. A large number of bridges (not shown) are connected between 16 at regular intervals, and a large number of container holders 18 are attached to these bridges at regular intervals. A number of holders 18 attached to the carrier 12 are supplied one by one in a container supply section (not shown) provided on the left side of FIG. Is conveyed. The container 10 held and transported by the holder 18 is sequentially washed through the immersion tanks 6A and 6B, and the container 10 that has passed through the immersion tanks 6A and 6B and appeared in the upper space is Liquids are sprayed from the cleaning nozzles 8Aa, 8Ba, and 8Ca to be cleaned by the chemical solution cleaning unit 8A, the rinse cleaning unit 8B, the finish cleaning unit 8C, and the like. The container 10 cleaned in each of the immersion tanks 6A, 6B and the cleaning units 8A, 8B, 8C is discharged from the container discharge unit 20 arranged at the right end in FIG. 1 and sent to the next step.

  After the holder 18 attached to the carrier 12 exits from the last immersion tank 6B and passes through the rinsing cleaning section 8B and the finishing cleaning section 8C, the container 18 continues until it reaches the sprocket 14 (14A) of the container discharge section 20. 10 is held in an inverted state, and the container 10 is inverted while rotating around the sprocket 14 </ b> A to erect the container 10. A discharge guide 22 that supports the bottom 10a of the container 10 is arranged along the movement path of the holder 18 from the side surface at the position where the holder 18 is reversed, and falls off the holder 18 when the holder 18 is reversed. The container 10 in a state moves together with the holder 18 with the bottom 10 a supported by the discharge guide 22. Since the container 10 is held at the top by the holder 18 and the bottom portion 10a slides and moves on the discharge guide 22, the mouth portion 10b side falls forward in the traveling direction due to frictional force with the discharge guide 22, and the bottom portion 10a moves rearward. Move with a delay.

  A downstream side of the discharge guide 22 is a discharge position of the container 10. A roller 24 is provided below the downstream end of the discharge guide 22, and a predetermined distance (interval through which the container 10 can pass) is separated from the roller 24. A chute 26 is arranged. The chute 26 is disposed so that the upper side is inclined toward the front side in the traveling direction of the carrier 12 (see arrow A). On the surface of the chute 26 on the side where the container 10 is dropped (the right surface in FIG. 2), guide rails 26a in the vertical direction are attached at regular intervals, and the number of rows of holders 18 attached to the carrier 12 It is divided into the same number of fall passages. Containers 10 for one row conveyed by the carrier 12 (the arrangement in the traveling direction A of the carrier 12 is referred to as a column and the arrangement in the direction orthogonal to the column is referred to as a row) pass through the downstream end of the discharge guide 22. At the same time, it comes out of the holder 18 and falls along the divided paths of the chute 26.

  A horizontal cradle 28 is disposed on the lower side of the chute 26 so as to face the surface on which the container 10 of the chute 26 slides down. The container 10 that has fallen on the chute 26 has a bottom portion at the tip of the cradle 28. 10a hits and stops. An inclined surface 28a having a gradient that is substantially perpendicular to the inclination of the chute 26 is formed at the tip of the cradle 28, and the bottom 10a of the container 10 that has dropped the chute 26 is the inclined surface (container receptacle). Surface) Stops on the surface 28a.

  A rotary cam 32 that rotates about the rotation shaft 30 is provided behind the chute 26 (behind the surface on which the container 10 slides down). The rotary cam 32 has a pair of cam plates 32 a and 32 b arranged at positions symmetrical with respect to the axis of the rotary shaft 30. The set of two cam plates 32a and 32b is arranged corresponding to each drop passage of the chute 26, and is equal to the number of rows of the holders 18 and the number of rows of the chute 26 attached to the carrier 12. Is provided. The two cam plates 32a and 32b are substantially semicircular plates attached to the rotary shaft 30 with their axial centers shifted in the opposite direction, and formed in each row of the chute 26 as the rotary shaft 30 rotates. The front slit of the chute 26 can be projected from the formed vertical slit (see the cam plate 32b positioned on the lower side of FIG. 2). Each of the cam plates 32a and 32b is configured to press and stand one container 10 while the rotary cam 32 rotates 180 degrees, and then advance on the cradle 28.

  A discharge conveyor 34 that travels in a direction orthogonal to the moving direction of the container 10 that is pushed and moved by the rotary cam 32 is disposed in front of the cradle 28 (to the right in FIG. 2). The containers 10 discharged by the container discharge unit 20 are conveyed in a row by the discharge conveyor 34 and sent to the next process.

  Next, the structure of the holder 18 will be described with reference to FIGS. The main body portion 36 of the holder 18 is basically cylindrical, and the end portion 36a (the upper end portion in FIG. 3A) on the side where the mouth portion 10b of the container 10 is inserted has a slightly smaller diameter. And a large-diameter portion 36c extending from the intermediate portion to the bottom side, and a tapered portion 36b from the upper end portion of the large-diameter portion 36c toward the small-diameter end portion 36a. In addition, although two containers 10 are described in the holder 18, the holder 10 is in an inverted state (FIG. 3A) in the container 10 (10A) that is entirely accommodated in the holder main body 36. The container 10 (10B) in which the bottom 10Ba is pulled out from the holder main body 36 is a state of the container 10B when the holder 18 is in the posture shown in FIG. Indicates the state.

  A plurality (eight in this embodiment) of ribs 38 are formed on the inner surface of the cylindrical holder main body 36 in parallel with the axis of the main body 36. These eight ribs 38 are continuously formed from the opening on the small diameter end portion 36 a side to the opposite end portion 36 d, that is, over the entire length of the holder main body portion 36. In the conventional holder 118 (see FIG. 5), a rib 138 formed on the inner surface of the main body 136 is provided from the opening on the small diameter end 136a side that accommodates the mouth 10b side of the container 10 to the tapered portion 136b. In this embodiment, the rib 38 is formed over the entire length from the small diameter end 36a to the other end 36d of the holder main body 36. . The number of ribs 38 is not limited to eight, but may be as many as necessary to prevent the container 10 from directly contacting the inner wall of the holder main body 36.

  Four ribs 38A provided every other rib 38 support the container 10A so that it does not come out when the holder 18 supports the container 10A in an inverted state, and perform centering. A portion 38Aa located in the opening on the small-diameter end portion 36a side is enlarged on the inner side (see the right halves of FIGS. 3A and 3B). Therefore, the circle connecting the tips of the enlarged portions 38Aa of the four ribs 38A is smaller than the diameter of the mouth portion 10Ab of the container 10A supported by the holder 18. Further, the four ribs 38B located between the ribs 38A on which the small-diameter end portion 36a side is enlarged do not have the enlarged portion 38Aa like the rib 38A, and are almost the same height as the other portions of the rib 38A. (See the left half of FIG. 3B). The number of the ribs 38A in which the enlarged portion 38Aa is formed on the small diameter end portion 36a side is not limited to four, and any other number can be used as long as the container 10A can be supported so as not to come out. Also good.

  The holder 18 provided with the ribs 38 (38A, 38B) having the above-described shape is conveyed in an inverted state, and then rotated around the sprocket 14A of the container discharge portion 20 to be reversed to bring the container 10 into an upright state. . When the container 10 (10B) is in an upright state and moves forward with the bottom 10Ba supported by the discharge guide 22, as shown in FIG. 3 (a), the mouth 10Bb side is directed forward in the traveling direction. It is conveyed in an inclined state. At this time, as shown in the left half of FIG. 3B, the opening 10Bb of the container 10B is not in direct contact with the inner wall of the holder main body 36 because it is supported by the ribs 38A and 38B. Even when the container 10 passes through the downstream end of the discharge guide 22 and falls out of the holder 18 and falls into the chute 26, the container 10B contacts only the ribs 38A and 38B. It does not move by rubbing the inner wall directly. Therefore, the friction when the containers 10B come out of the holder 18 is reduced, and the drop timing of the containers 10B in each row is not shifted. Further, even when the scale is deposited on the inner surface of the holder main body 36, the mouth portion 10Bb of the container 10B does not come into direct contact, so there is no possibility of adhering to the container 10B. In addition, water droplets adhering to the inner wall of the holder main body 36 do not enter the container 10B.

  In the above-described embodiment, the eight ribs 38 (38A, 38B) are evenly arranged on the entire inner surface of the holder main body 36. However, as described above, the container discharge portion 20 has the mouth portion of the container 10B. Since 10Bb is inclined and moved so as to face the front side in the traveling direction, the rib for preventing the mouth portion 10Bb of the container 10B from contacting the holder main body portion 36 is a portion where the mouth portion 10Bb of the container 10B may hit. Only need to be provided. FIG. 4 shows an embodiment in which ribs are provided for such a purpose, and ribs for preventing the mouth 10b of the container 10 (not shown in FIG. 4) from contacting the inner wall of the holder main body 36. 38C (see FIGS. 4B to 4D) is provided only before and after the holder 18 in the traveling direction. In this embodiment, two ribs 38C having a length extending over the entire length of the holder main body 36 are formed on the front and rear sides. Further, in each of the embodiments, the rib 38 having a length over the entire length of the holder main body 36 is provided, but the length of the rib 38 does not necessarily have to extend over the entire length, and may be interrupted in the middle. In any case, the opening 10Bb of the falling container 10B may not be in contact with the inner surface of the holder main body 38.

  Further, when the container 10 is supported in an inverted state between the ribs 38C for preventing the mouth portion 10b of the container 10 from coming into contact with the holder main body portion 36, the container 10 is prevented from coming out and centering is performed. A rib 38D is provided for performing (see FIGS. 4A to 4B). The rib 38D only needs to be provided on the small diameter end portion 36a side where the container mouth portion 10b of the holder main body portion 36 is inserted, and is provided from the tapered portion 36b to the small diameter end portion 36a. And the part 38Da in the opening part by the side of the small diameter end part 36a is expanded inside. The rib 38C for preventing contact of the container mouth portion 10b only needs to prevent the contact of the mouth portion 10b of the container 10, and there is no need to expand the opening side inward like the rib 38D for centering. Also in this embodiment, since the rib 38C is formed in the portion where the mouth portion 10b of the container 10 abuts when the container 10 is discharged from the holder 18 by the container discharge portion 20, the same effects as the above-described embodiment are achieved. be able to.
