Next, an embodiment of a tray replenishment method using this replenisher will be described.
In this replenishing device, the stacking tray 2 is received by the holding member 15a of the transfer member 13, rotated 90 degrees around the support shaft 14, and replenished into the transfer gutter 3, and one side D is supplied from the supply means. Using a rectangular tray F having a constant dimension that fits a constant width Da of the piling material, and the other side E having a dimension E set according to the amount of piling on the tray 1, this tray F is When the stacked trays Fm for replenishment are placed with one side D facing the receiving shelf 10 of the replenishment device, and are replenished into the guide gutter 3 by changing the posture by the transfer tool 13, the tray separating means When the separated tray F is sent to the serving position by the chain conveyor C, one side D of the tray F faces the width Da side where the sliced meat serving as the serving material is divided into packs and sent out by the belt conveyor 9. You can arrange it smoothly.
In this case, even if one side E of the tray F is lengthened in order to increase the amount of loading on one tray F, the stacked trays Fm placed on the receiving shelf 10 will be , so there is no effect on the traversing means and no adjustment is required.
In addition, since the tray F conveyed by the chain conveyor C has one side D of a certain dimension along the conveying direction of the tray F, the locking pieces 7 contact the rear wall of the tray F to convey the tray F. The interval may be constant.

When using a tray F whose other side E is shorter than one side D of the tray F, the stacked tray Fm is placed with one side D side of a certain size facing the receiving shelf 10, and the posture is changed by the transfer tool 13. However, when there are many operations using trays F whose other side E is shorter than one side D, the short side E side of the stacked trays Fm is placed on the receiving shelf 10. Then, the holding member 15a of the transfer member 13 is withdrawn, and the stacked tray Fm is replenished into the guide gutter 3 in the placed posture, so that one side D can face the width Da of the piled material.
In this case, it is necessary to adjust the lateral feeding means according to the dimension of the short side E, but by placing the trays with the short side E facing the receiving shelf 10, the loading capacity of the stacked trays for replenishment is increased. be able to.

In this way, by moving the transfer member 13 forward and backward, it is possible to change the replenishment posture of the replenishment lamination tray 2 (Fm) into the guide gutter 3, so that the short side of the lamination tray 2 faces the tray 10. Even if it is placed, it is possible to match the attitude of the serving material, and if the placement capacity of the receiving shelf 10 of the stacking tray 2 for replenishment increases, the time until the next placement is increased accordingly, so it is efficient. It can be used properly according to the situation, such as arranging work.
