BACKGROUND OF THE INVENTION
The present invention relates to a cup elevating device for elevating a cup guided through a chute and placed upright on a placement plate so as to inject a beverage such as beer by approaching a discharge nozzle above the cup, for example. About.
[0002]
[Prior art]
A conventional example will be described below with reference to FIG. 3 based on the prior art described in JP-A-8-273050. FIG. 3 is a side view and (b) is a plan view of this conventional example. In these figures, the cup 9 with a circular bottom slides down to the lower right along the left bowl-shaped chute 3 and stands upright on the mounting plate 1 at a position concentric with the hole 31 formed therein. Placed. In order to make the position where the cup 9 is placed constant and to place it stably, the support 34 located on the right side supports the cup 9 from the side. That is, the support 34 is a plate-like member formed on the U-shaped frame on the upper side and on the curved surface in contact with the outer peripheral surface of the cup 9 on the upper side. It is supported so as to be able to swing by a shaft 6 that is prevented from coming off by a retaining ring that is not attached. The support 34 is weakly urged around the shaft 6 by a torsion spring and a stopper (not shown) provided around the shaft 6 in the clockwise direction in FIG. It can be positioned and placed at a predetermined position. By the way, since the discharge valve 10 is installed at a position above the cup 9, the cup 9 slides down along the chute 3 and stands upright on the mounting plate 1 at a position concentric with the hole 31. Will not interfere with it.
[0003]
In FIG. 3 (a), a circular hole 31 smaller than the bottom diameter of the cup 9 is made in the center of the mounting plate 1. The cradle 32 is a disk smaller than the diameter of the hole 31 and is fixed to the tip of the output shaft 21 of the pneumatic operation cylinder 22. The operation cylinder 22 is installed with the axis line vertical, and the cup 9 is lifted together with the cradle 32 by introduction of compressed air, and this allows the injected beer to be properly foamed with respect to the discharge nozzle 10a of the discharge valve 10. Positioning is performed at a predetermined level, that is, as indicated by a one-dot chain line. The cup 9 is lowered after pouring beer and returned to the position of the solid line on the mounting plate 1 and waits for the customer to be taken out from the paper side in FIG.
[0004]
In FIG. 3 (a), the cup 9 is placed on the cradle 32 and moved up and down to inject beer into the discharge nozzle 10a and the cup 9 placed at the optimum position. This will be described with reference to the block diagram of the draft beer supply device in FIG. The gas pressure of the carbon dioxide cylinder 11 is applied to the draft beer barrel 13 via the pressure reducing valve 12 and the gas hose 16. The degree of pressurization is adjusted by the pressure reducing valve 12 according to the temperature of beer. Now, by this gas pressure, the beer stored in the draft beer barrel 13 passes through the supply head 14, the beer hose 17, the cooling water tank 15 and the beer hose 18 and is cooled to an appropriate temperature from the discharge valve 10 of the piping terminal. Discharged. It becomes an important condition for drinking and making a beer delicious when the cup 9 receives the discharged beer. One major factor for obtaining this proper foaming state is the level positional relationship between the nozzle 10a of the discharge valve 10 and the cup 9. That is, in order to obtain a proper foaming state for drinking beer well, it is necessary to position the nozzle 10a into a predetermined proper position by pushing it into the opening space of the cup 9, and this proper position is determined based on experiments. Is required.
[0005]
[Problems to be solved by the invention]
In the conventional example, it is ideal to place the cup 9 directly above the hole 31 of the mounting plate 1 through the chute 3 and the support 34. However, since it is inevitable that the direction (posture) and speed of the cup 9 when sliding down the chute 3 are inevitably varied, the mounting position of the cup 9 tends to be slightly biased toward the chute 3 from the hole 31. There is. Thus, when the cup 9 is mounted on the mounting plate 1, the bias toward the side of the chute 3 is such that the cup 9 is pushed back under the bias of the support 34. It is because it does not become biased to the side of the.
[0006]
FIGS. 2A and 2B relate to the relationship between the cup and the hole of the mounting plate. FIG. 2A is a schematic view seen from the top surface, and FIG. 2B is a schematic view seen from the side surface. In FIG. 2 (a), ideally, the circular bottom of the cup (indicated by a broken line) is a concentric circle having a slightly larger diameter with the original hole-shaped circle in the conventional example, and takes the position (1). The cross-hatched arcuate portion is not described here as it will be described later. The circular bottom of the cup is actually placed at a position of {circle around (2)}, that is, slightly to the chute side by the amount of eccentricity e, as indicated by the dashed line. Then, in Fig. 2 (b), the end of the cup bottom support side (right side in the figure) is slightly fitted into the hole shape due to inertia or momentum when landing. It will be slightly tilted from position (2) A to position (2) B. In many cases, the cup 9 returns to a normal posture only by being tilted temporarily. However, due to the flexibility of the peripheral wall, the cup 9 sometimes stays in the original shape hole and remains tilted. There arises a problem that placement in a normal upright posture is hindered. Returning to FIG. 3, it is necessary to make the diameter of the cradle 32 as large as possible and stably receive the bottom of the cup 9, and therefore the diameter of the hole 31 cannot be made much smaller than the bottom diameter of the cup 9. In other words, the fact that the tolerance of variation related to the landing position cannot be made too large promotes the above-described problem. In addition, in the conventional example, when the cup 9 is raised, the support 34 is not supported and the stability may be hindered.
[0007]
The problem to be solved by the present invention is that the bottom edge of the cup is partially fitted into a hole formed in the mounting plate due to variations in direction and speed when the cup is guided through the chute. An object of the present invention is to provide a cup elevating device that prevents the upright posture from collapsing, and further supports the cup to be stable during ascent.
[0008]
[Means for Solving the Problems]
The present invention relates to a mounting plate for placing a cup guided through a chute upright, and a support member disposed so as to face the terminal portion of the chute across a hole formed in the mounting plate. In a device for raising and lowering the placed cup through a cup cradle that goes up and down through the hole of the placement plate,
The hole of the mounting plate has a configuration in which a hole corresponding to the cup bottom is used as an original shape and an end edge portion on the support member side is partially blocked.
[0009]
Here, the present invention has a configuration in which the cup has a circular bottom, and the hole of the mounting plate has a circular shape corresponding to the cup bottom as an original shape and the edge portion is closed by an arcuate shape. preferable.
Moreover, it is preferable that this invention is a structure with which a support is provided with the guide which can be guided, supporting the cup which raises / lowers from a side.
[0010]
Furthermore, it is preferable that the present invention is configured to include an auxiliary guide that can guide the cup that moves up and down while supporting the cup from the side perpendicular to the support.
Therefore, in the present invention, the cup should be placed upright so that the cup is guided by the chute and placed concentrically on the mounting plate almost directly above the hole. Even when the cup is biased to exceed the allowable value on the chute side when landing due to the variation of the height, the bottom edge of the support side is partially fitted into the hole of the mounting plate by the following configuration. Can prevent the upright posture from collapsing. The configuration is such that the hole on the mounting plate is formed in a shape corresponding to the bottom of the cup, and the end portion on the support member side is partially closed by, for example, an arcuate shape. In other words, even if the bottom edge part of the cup supporter side is slightly shifted to the chute side and partially landed in the hole corresponding to the cup bottom, the end of the closed original hole is closed. This is because it is received by the edge portion, for example, an arcuate portion.
[0011]
In the present invention, the elevating cup is guided by the guide attached to the support while being supported from the side facing the chute.
Furthermore, in the present invention, the ascending / descending cup is guided by the auxiliary guide while being supplementarily supported from the side perpendicular to the support.
