In addition, the left tableware holder 30 and the right tableware holder 31 in the lower tableware holding unit 21 have the second follower 47 of the left tableware holder 30 when the tableware extraction unit 35 is displaced from the extraction position to the standby position. Since the second follower 49 of the right tableware holder 31 moves along the first guide edge 54 of the second cam groove 50 while moving along the first guide edge 54 of the second cam groove 48, the upper tableware D2 of the upper tableware D2 is moved. It will be held in the tableware holding position.

(Operation of the first embodiment)
Next, the operation of the tableware dispenser M of the first embodiment configured as described above will be described with reference to FIGS. 6 and 7, in order to make it easy to understand the interlocking mode of the tableware holding unit 20 and the tableware extraction unit 35, the arrangement direction of the tableware extraction unit 35 with respect to the tableware holding unit 20 is changed from that in the first embodiment. It is displayed.

  First, as shown in FIG. 6 (a), the tableware take-out portion 35 is held at the standby position, and the released lower tableware D1 is accommodated and held in the tableware receiving portion 36 of the tableware take-out portion 35. The lower tableware holding unit 21 and the upper tableware holding unit 22 are both stopped at the tableware holding position, and the lower tableware holding unit 21 does not hold the lower tableware D1. The tableware holding unit 22 holds the upper tableware D2. A plurality of tableware D are stacked above the upper tableware D2.

  In the state of FIG. 6 (a), when the tableware extraction operation is performed by the extraction lever L, the tableware extraction unit 35 is displaced from the standby position toward the extraction position due to the weight of the lower tableware D1 (FIG. 6 (b)). )). In this posture change of the tableware take-out section 35, the left tableware holder 30 and the right tableware holder 31 of the upper tableware holding section 22 return to the tableware holding state again after being displaced from the tableware holding position to the tableware opening position. Accordingly, the upper tableware D2 held by the upper tableware holding unit 22 moves downward, and is held as the lower tableware D1 by the left tableware holding body 30 and the right tableware holding body 31 of the lower tableware holding unit 21, and The tableware holding unit 22 holds a new upper tableware D2.

  When the tableware D is removed from the tableware receiving portion 36 of the tableware removal portion 35 whose posture has been displaced to the removal position (FIG. 7A), the tableware removal portion 35 is moved from the removal position to the standby position by the biasing force of the torsion spring 38. The posture is displaced. In this attitude change of the tableware take-out section 35, the left tableware holder 30 and the right tableware holder 31 of the lower tableware holding section 21 are displaced from the tableware holding position to the tableware release position, and then return to the tableware holding position again. Accordingly, the lower tableware D1 held in the lower tableware holding unit 21 is discharged downward and received by the tableware receiving unit 36 of the tableware extraction unit 35 immediately before returning to the standby position (FIG. 7B). Then, when the tableware take-out section 35 returns to the standby position, the state shown in FIG. Note that the tableware D received in the tableware receiving unit 36 is appropriately heated by operating the heater 39 of the tableware receiving unit 36 of the tableware extraction unit 35.

  Therefore, according to the tableware dispenser M of the first embodiment, the lower tableware holding portion 21 that holds the lower tableware D1 positioned at the bottom of the stacked tableware D and the directly above the lower tableware D1. The upper tableware holding unit 22 that holds the upper tableware D2 that is positioned and the tableware extraction unit 35 whose posture is displaced between the standby position and the extraction position are linked by the linkage mechanism 40. It can be taken out and used. Therefore, since the tableware D stacked one by one from the top can be taken out one by one from the bottom, only the upper tableware D stacked is used frequently, or the tableware D stacked below is used frequently. Since the frequency of use of all tableware D is not lowered, the life of each tableware D does not vary. Moreover, since all the tableware D is used repeatedly, it is hard to adhere dust, dust, etc. to the tableware D piled on the lower side, and it is not necessary to wash again before use.

  In the tableware dispenser M of the first embodiment, the tableware holding unit 20 includes the lower tableware holding unit 21 and the upper tableware holding unit 22, and the left tableware holding body 23 and the right tableware holding body 24 in the lower tableware holding unit 21.

Can be released appropriately. The tableware dispenser M of the first embodiment can hold the upper tableware D2 by moving the left tableware holding body 30 and the right tableware holding body 31 in the upper tableware holding section 22 close to the tableware holding position, When the tableware holder 30 and the right tableware holder 31 are moved apart to the tableware release position, the upper tableware D2 can be appropriately discharged downward. Accordingly, the upper tableware D2 positioned right above the lower tableware D1 positioned at the bottom of the stacked tableware D is held by the upper tableware holding unit 22, and the lower tableware is operated by the lower tableware holding unit 21. Only tableware D1 can be discharged appropriately. Further, since the first linkage portion 41 and the second linkage portion 42 of the linkage mechanism 40 are a combination of a cam groove and a follower that slidably engages with the cam groove, the posture displacement of the tableware take-out portion 35 can be changed. It can be reliably converted into the posture displacement of the lower tableware holding unit 21 and the upper tableware holding unit 22.

  Further, since the tableware take-out section 35 for receiving the released lower tableware D1 is provided, the tableware D released from the tableware holding section 20 is appropriately received by the tableware receiving section 36 of the tableware take-out section 35, and the tableware D Can be suitably prevented. In addition, since the tableware receiving unit 36 of the tableware extraction unit 35 is provided with the heater 39, the tableware D extracted from the tableware extraction unit 35 is warmed to an appropriate temperature, and the food served on the tableware D is cooled. It becomes difficult.

  In the tableware dispenser M of the first embodiment, the interval between the left tableware holder 30 and the right tableware holder 31 of the lower tableware holder 21 is adjusted, and the left tableware holder 30 of the upper tableware holder 22 and By adjusting the arrangement interval of the right tableware holding body 31, it is possible to hold tableware D of various sizes, and by changing the shapes of the left tableware holding body 30 and the right tableware holding body 31, various shapes can be obtained. The tableware D can be held. Moreover, the tableware D in which stacking intervals differ can also be hold | maintained by adjusting the arrangement | positioning space | interval of the upper tableware holding part 22 and the lower tableware holding part 21.

Two upper sprockets 65 and two lower sprockets 66 are provided at predetermined intervals in the axial direction of the respective rotating shafts 63 and 64 (see FIG. 9), and are wound around the upper sprocket 65 and the lower sprocket 66, respectively. Chains 67 and 67 are configured to rotate synchronously. On the outer peripheral surface of each chain 67, as shown in FIG. 10, a plurality of tableware holders 68 extending in the lateral direction and coming into contact with the tableware D are provided at the required intervals in the circumferential direction of the chain 67 (first number). 12 in the second embodiment). The first tableware holding unit 61 and the second tableware holding unit 62 include guide plates 73 and 73 in which guide grooves 70 are formed facing each other in the axial direction of the rotation shafts 63 and 64. A guide pin 69 that slides in the guide groove 70 is provided.

  The first tableware holding unit 61 and the second tableware holding unit 62 are linked to each other by rotating gears 63 and 63 by a gear or chain (not shown), and the side close to the stacked tableware D moves downward. It is designed to rotate synchronously in the opposite direction. The first tableware holding unit 61 and the second tableware holding unit 62 are arranged so that the tableware holding body 68 comes into contact with the tableware D in the upper winding position 67A wound around the upper sprocket 65 in the chain 67, and the chain 67 The tableware holding body 68 positioned at the interwinding position 67B between the upper sprocket 65 and the lower sprocket 66 at the position abuts against the stacked tableware D, and at the lower winding position 67C where the lower sprocket 66 is wound around the chain 67. The tableware holder 68 is configured to be separated from the tableware D. The first tableware holding unit 61 and the second tableware holding unit 62 are configured so that three to four tableware holding bodies 68 exist at the position 67B between the windings during rotation of the chain 67. Stacked 3 to 4 tableware D can be held simultaneously.

  And the tableware holding mechanism 60 in the tableware dispenser M of 2nd Example can adjust the space | interval between the 1st tableware holding part 61 and the 2nd tableware holding part 62, and respond | corresponds to the tableware D of various sizes. obtain. Further, by adjusting the arrangement interval of the tableware holding body 68 with respect to the chain 67, it is possible to deal with tableware D having a different stacking interval H (see FIG. 10). As shown in FIG. 10, the guide groove 70 is formed with a curved portion 71 that protrudes toward the tableware D side at a position corresponding to the upper portion of the chain 67 between the winding positions 67 </ b> B. Accordingly, when the arrangement interval W of the tableware holding bodies 68 with respect to the chain 67 cannot be matched with the stacking interval H of the tableware D, the arrangement interval W of the tableware holding bodies 68 is set to the stacking interval of the tableware D. By setting it appropriately larger than H, the tableware D can be appropriately held by each tableware holding body 68. That is, as shown in FIG. 10, the tableware holding body 68 that has arrived at the curved portion 71 of the guide groove 70 is displaced so that its tip side faces obliquely upward. The tableware D is pushed up appropriately. For this reason, the next tableware holder 68 can be appropriately inserted between the tableware D pushed up directly and the tableware D stacked just above the tableware D.

  The tableware take-out section 80 has the same basic configuration as that of the first embodiment, and as shown in FIGS. 8 and 9, the lower tableware D1 discharged downward from the tableware holding mechanism 60 can be received upward. A bucket-shaped dish receiving portion 81 that is open to the bottom, and a cylindrical support tube portion that is provided so as to extend horizontally on the rear side of the tableware receiving portion 81 and allows insertion of a support shaft provided on the frame 82. Further, as shown in FIG. 8, the support cylinder portion 82 is provided with a linkage gear 83 that is used for linkage with the tableware holding mechanism 60.

  The linkage mechanism 85 in the tableware dispenser M of the second embodiment is linked to the linkage gear 83 provided in the tableware take-out section 80 and is connected to the lower rotary shaft 64 in the first tableware holding section 61 of the tableware holding mechanism 60. A one-way clutch 86 linked to the provided gear 72 is provided. The one-way clutch 86 does not transmit the posture displacement of the tableware removal unit 80 to the tableware holding mechanism 60 when the tableware extraction unit 80 is displaced from the standby position to the extraction position, for example. When the posture is displaced to the standby position, the posture displacement of the tableware take-out unit 80 is transmitted to the tableware holding mechanism 60, and the first tableware holding unit 61 and the second tableware holding unit 62 of the tableware holding mechanism 60 are moved by one stroke ( The operation is performed by the arrangement interval W) of the tableware holder 68.

Tableware holding mechanism 60 capable of discharging the tableware downward and tableware take-out portion 80 whose posture is displaced between the standby position and the take-out position are linked by linkage mechanism 85, so that stacked tableware D is sequentially taken out from below and used. The same effects as the tableware dispenser M of the first embodiment can be obtained. Thereby, since the tableware D stacked sequentially from the top can be taken out sequentially from the bottom, only the upper tableware D stacked is used frequently, or the tableware D stacked below is used less frequently. Since the usage frequency of all tableware D is equal, there is no variation in the life of each tableware D. Moreover, since all the tableware D is used repeatedly, it is hard to adhere dust, dust, etc. to the tableware D piled on the lower side, and it is not necessary to wash again before use.

  In addition, each of the chains 67 of the first tableware holding unit 61 and the second tableware holding unit 62 of the tableware holding mechanism 60 rotates synchronously, so that the tableware holding body 68 and the second tableware holding unit 62 of the first tableware holding unit 61 are rotated. With the upper tableware D2 held by the tableware holding body 68, the lower tableware D1 can be appropriately discharged, and the stacked tableware D can be sequentially released one by one while moving downward. . In addition, since the linkage mechanism 85 includes the one-way clutch 86, the tableware D is not released from the tableware holding mechanism 60 when the tableware extraction unit 80 is displaced from the standby position to the extraction position, and the tableware D is extracted. When the take-out section 80 is displaced from the take-out position to the standby position, the lower tableware D1 is released from the tableware holding mechanism 60, and the lower tableware D1 that has been released is not damaged, and is suitable for the tableware take-out section 80. Can accept. Furthermore, if the tableware receiving unit 81 of the tableware extraction unit 80 is provided with a heater as a temperature adjusting means as in the first embodiment, the tableware D extracted from the tableware extraction unit 80 is warmed to an appropriate temperature. It is difficult for the food to be placed on the tableware D to be cooled.

  FIG. 11 is an explanatory view schematically showing an automatic placement machine N equipped with the tableware dispensing mechanism K including the tableware dispenser M of the first embodiment or the tableware dispenser M of the second embodiment. The tableware take-out mechanism K is disposed so as to pass through the tableware dispenser M of the first embodiment or the second embodiment and the food applicator J from the tableware dispenser M, and the tableware extraction unit 35 of the tableware dispenser M is provided. , 80 is provided with tableware transport means C for transporting the tableware D taken out from 80 to the food applicator J. The tableware conveying means C is a belt or a caterpillar-shaped rotary moving body. The food serving portion J includes a mechanism for serving predetermined food on the tableware D positioned downward via the tableware transport means C. In addition, the tableware transfer means which transfers the tableware D from the tableware extraction parts 35 and 80 to the tableware conveyance means C is provided as needed.

  Therefore, the automatic leveling machine N equipped with the tableware take-out mechanism K shown in FIG. 11 takes out the tableware D stacked on the tableware dispenser M one by one from the bottom, and the tableware D is supplied to the food via the tableware conveying means C. The food can be appropriately placed on the tableware D while being transported to the serving portion J. Therefore, the automatic placement machine N shown in FIG. 11 can efficiently take out all of the tableware D stacked on the tableware dispenser M and efficiently arrange food on the tableware D.
