The dispensing device 20 includes an opening / closing mechanism 40 that opens or closes the internal flow path 34 with respect to the spout 36. The opening / closing mechanism 40 of the present embodiment is accommodated in the second internal flow path 34b in the internal flow path 34, and the beverage product in the second internal flow path 34b is opened or closed by opening or closing the second internal flow path 34b. It supplies to the spout 36, or the supply to the spout 36 of the drink is interrupted. The opening / closing mechanism 40 includes a valve body 41 that opens or closes the second internal flow path 34 b with respect to the spout 36. In this exemplary pouring device 20, the valve element 41 is disposed so as to be able to reciprocate along the axial direction of the second internal flow path 34b, and the peripheral edge on the second internal flow path 34b side in the third cylindrical portion 31C is disposed. It is used as a valve seat 31C _1. Closing mechanism 40, or to depending on the position in the axial direction of the valve body 41 against its seat 31C _1, and open or close the inner flow passage 34, communication between the spout 36 and the second internal flow path 34b , Or block this. Valve body 41 includes a main body portion 41A that axially reciprocable movement of the second tubular portion 31B, attached to the main body portion 41A, a seal member 41B which is interposed between the main portion 41A and the valve seat 31C ₁ , Is composed of. In the valve body 41, the reciprocating direction is the opening / closing direction of the internal flow path 34. The main body portion 41A is a column that extends in the axial direction of the second cylinder portion 31B (second internal flow path 34b), and is formed of a hard synthetic resin material or the like. On the other hand, the seal member 41B is capable of abutting against the annular body to the valve seat 31C ₁ when the valve is closed, to reciprocate in unison with the main body portion 41A. The seal member 41B is formed of an elastic synthetic resin material or the like in order to prevent the beverage from leaking from the spout 36 when the valve is closed.

The opening / closing mechanism 40 includes a shaft member 42 having a valve body 41 attached to one end thereof. The shaft member 42 is formed of a hard synthetic resin material or the like. The shaft member 42 is a member having an axial main portion (hereinafter referred to as “shaft portion”) 42a extending in the axial direction of the second cylindrical portion 31B (second internal flow path 34b). It can be reciprocated in the direction (that is, the opening / closing direction of the valve body 41). A main portion 41A of the valve body 41 is attached to one end of the shaft portion 42a in the axial direction via an elastic member 43A such as a string spring. For example, a holding portion 42b is provided at one end of the shaft portion 42a, and one end of the elastic member 43A is fixed via the holding portion 42b. For this reason, the shaft member 42 can move relative to the valve body 41 in the axial direction or reciprocate together with the valve body 41 in the axial direction according to the force generated by the elastic member 43A. Elastic members 43A causes the compression by the user moves the shaft member 42 when closed operation (i.e. when the valve is closed operation for valve closing operation of the valve body 41) toward the valve seat 31C ₁ side, a valve body 41 by the action of a reaction force corresponding to the compression forces between the shaft member 42 presses the sealing member 41B of the valve element 41 to the valve seat 31C _1. On the other hand, the elastic member 43A moves the shaft member 42 in the direction opposite to that during the closing operation when the user performs the opening operation (that is, during the valve opening operation for opening the valve body 41). 41 and the tensile force is generated between the shaft member 42, separating the sealing member 41B of the valve element 41 from the valve seat 31C _1.

The elastic member 43B is compressed regardless of whether the valve is closed or not, and applies a reaction force corresponding to the compressive force between the holding part 42b and the disk part 32a. The elastic member 43B is formed so as to generate a larger compressive force than the elastic member 43A when the spring constant is made larger than that of the elastic member 43A and the amount of change is the same. For this reason, the elastic member 43B has an axis line directed toward the valve body 41 with respect to the shaft member 42 in the closed state (that is, the closed state in which the valve body 41 closes the second internal flow path 34b). A directional pressing force is generated to maintain this closed state. Further, the elastic member 43B generates a force in a direction in which the shaft member 42 is pressed against the valve body 41 between the elastic member 43B and the operation force of the operation lever 50 (to be described later) of the user during the closing operation. Can be relaxed.

  The shaft portion 42 a of the shaft member 42 projects the other end in the axial direction to the outside of the housing 30.

The operation mode of the lock mechanism 60 changes depending on whether or not the user performs an unlock operation. The lock mechanism 60 prohibits the valve opening operation of the valve element 41 of the opening / closing mechanism 40 unless the unlocking operation is performed. On the other hand, the lock mechanism 60 permits the valve opening operation of the valve body 41 by performing the unlocking operation.

  For example, the lock mechanism 60 of the present embodiment includes a shaft member (hereinafter referred to as “lock shaft member”) 61 capable of stopping the valve opening operation of the valve body 41. The lock shaft member 61 is formed in a cylindrical shape with a hard synthetic resin material or the like, and is inserted into the internal space of the fourth cylinder portion 31D with the axis directions thereof aligned. That is, the lock shaft member 61 is arranged with its own axial direction orthogonal to the opening / closing direction (reciprocating direction) of the valve body 41. The lock shaft member 61 is disposed so as to protrude outward and inward (on the second internal flow path 34b side) of the housing 30 through the fourth cylinder portion 31D. In the second internal flow path 34b, the lock shaft member 61 is inserted through the through hole 41a formed in the valve body 41. The through hole 41 a is a hole orthogonal to the opening / closing direction of the valve body 41. A projecting portion 41b that projects from the inner wall surface of the through hole 41a toward the opening / closing direction of the valve body 41 is provided inside the through hole 41a. On the other hand, the lock shaft member 61 is provided with a groove portion 61a into which the protruding portion 41b can be inserted.

  The lock mechanism 60 includes an elastic member 62 such as a coiled spring between a flange 61b provided at an outer end of the housing 30 of the lock shaft member 61 and an end surface on the protruding side of the fourth cylindrical portion 31D. Provided. The elastic member 62 is a compression spring that constantly generates a compression force therebetween, and the reaction force corresponding to the compression force pushes the lock shaft member 61 outward of the housing 30 in its own axial direction. doing. Since the wall surface of the groove portion 61a is locked to the wall surface of the protruding portion 41b by the reaction force from the elastic member 62 at a predetermined position with respect to the fourth cylinder portion 31D, the lock shaft member 61 is locked at the predetermined position of the housing 30. The outward movement stops. In that case, in the valve body 41, the pressing force is acting on the wall surface of the protrusion part 41b from the wall surface of the groove part 61a. In the lock mechanism 60, even if the operation lever 50 is opened and a force in the valve opening direction acts on the valve body 41, the elastic member prevents the valve body 41 from moving in the valve opening direction by the pressing force. 62 characteristics are set. Therefore, the lock mechanism 60 is in a locked state when the lock shaft member 61 is in a predetermined position, and can stop the movement of the valve element 41 in the valve opening direction even if the operation lever 50 is opened. In this example, the shaft member 42 moves relative to the valve body 41 when the operation lever 50 is opened in the locked state.

The user pushes the lock shaft member 61 in the axial direction from the predetermined position toward the inward side of the housing 30 in order to release the lock state of the lock mechanism 60. Therefore, the lock mechanism 60 includes an operation button (hereinafter referred to as “unlock button”) 63 that pushes the lock shaft member 61 in the axial direction from the outer side to the inner side of the housing 30. The unlock button 63 is formed of a hard synthetic resin material or the like in a cylindrical shape with one end closed, and is disposed concentrically with the fifth cylinder portion 31E so as to close the opening provided in the disk portion of the fifth cylinder portion 31E. The The lock release button 63 is disposed so as to be able to move relative to the fifth cylinder portion 31E in the axial direction. When performing the unlocking operation, the user pushes the unlock button 63 toward the inside of the housing 30. Thereby, in this lock mechanism 60, the inner wall surface of the disk-shaped closing part in the lock release button 63 directly or indirectly pushes the flange 61b of the lock shaft member 61, and the wall surface and the protruding part of the groove part 61a. The locked state is released while decreasing the pressing force generated between the wall surface 41b. In the dispensing device 20, when the operation lever 50 is opened, the valve body 41 moves away from the valve seat 31 </ b> C _{1 as the} pressing force decreases.

  Here, the locking mechanism 60 is provided with a rectangular locking portion 64 that can enter and exit in the radial direction with respect to a hole formed in the outer peripheral surface of the lock shaft member 61. The locking portion 64 applies a pressing force to the inner wall surface of the inner space of the fourth cylinder portion 31D when in the locked state (when the lock shaft member 61 is in a predetermined position). The pressing force is generated by an elastic member 65 such as a string spring provided in the hole of the lock shaft member 61. By locking the shaft member 42 so that the locking portion 64 does not enter the second internal flow path 34b, the lock shaft member 61 is not moved from the predetermined position toward the second internal flow path 34b (that is, locked). A protrusion 42c is provided to prevent the state from being released.

  The projecting portion 42 c projects from the holding portion 42 b toward the lock shaft member 61 in the reciprocating direction of the shaft member 42. The projecting side end of the projecting part 42c is opposed to the wall surface of the locking part 64 on the second internal flow path 34b side in the axial direction of the lock shaft member 61 in the locked state. Thereby, in the lock mechanism 60, even if the user tries to push the lock release button 63 inward of the housing 30, the locking portion 64 is locked to the protruding portion 42c. Cannot be moved from the predetermined position to the second internal flow path 34b, and the locked state is not released. On the other hand, in the lock mechanism 60, when the operation lever 50 is opened, the locking portion 64 is not locked to the protruding portion 42c, so that the user moves the lock release button 63 to the inside of the housing 30. When pushed, the lock shaft member 61 moves from the predetermined position toward the second internal flow path 34b, and with the movement of the lock shaft member 61, the protruding portion 41b of the valve body 41 comes out of the groove portion 61a, and the locked state is released. The At this time, in the dispensing device 20, the valve body 41 is pulled up by the shaft member 42 and opened. In the unlocked state, the locking portion 64 protrudes from the hole of the lock shaft member 61 more than in the locked state, and is locked to the fourth cylinder portion 31D as it is, so that the lock shaft member 61 is locked. It does not return to the position. At that time, the protruding end surface of the protruding portion 42c faces the top surface of the locking portion 64 (the portion that applies a pressing force to the inner wall surface of the fourth cylinder portion 31D). For this reason, in the lock mechanism 60, when the user releases the lock release button 63 and the operation lever 50 is closed, the end surface of the protruding portion 42c pushes the locking portion 64 back into the hole. Then, the lock shaft member 61 is pushed to a predetermined position by the elastic member 62, and the projecting portion 41b of the valve body 41 is inserted into the groove portion 61a to be locked again.

  By the way, in this extraction | pouring apparatus 20, the operation lever 50 can switch the position with respect to the housing | casing 30 as follows. For example, the operation lever 50 of the present embodiment can perform a switching operation between at least the closed lever position shown in FIG. 4 and the opened lever position shown in FIG.

The closed lever position is the position of the operation lever 50 when the valve body 41 closes the internal flow path 34 and indicates the position when the user is not operating the operation lever 50. ing. Support 52, the operation lever 50 has a first opposing portion 52a opposite to the opposing portion 32a ₁ of the first cover member 32 when the closure time of lever position. The first facing portion 52a is formed by a certain one side of each side wall portion 52A.

The opened lever position is the position of the operating lever 50 when the valve body 41 opens the internal flow path 34 and the user presses the operating lever 50 with a cup through the protection member 53. This represents the position when a moving operation (opening operation) is performed. Support 52 has upon opening operation from the closed when the lever position of the operation lever 50 to open when the lever is positioned, the fulcrum portion 52b as the fulcrum in contact with the object to be opposed portion 32a ₁ at an eccentric position relative to the axis of rotation 45 (Fig. 3). The fulcrum part 52b is a part that opens the internal flow path 34 by moving the rotary shaft 45 as the action point part together with the shaft member 42 in the valve opening direction during the opening operation. The fulcrum part 52b is formed as a corner on one end side of the side forming the first facing part 52a in each side wall part 52A.

  Furthermore, the operation lever 50 of this embodiment can also perform switching operation between the closed lever position and the maintenance lever position shown in FIG. The maintenance lever position refers to the position of the operation lever 50 when performing the attaching / detaching operation (screwing operation or the like) of the dispensing device 20 (housing 30) with respect to the feeder main body 10. Specifically, the third extending portion of the lever main body 51 in the traveling direction of the housing 30 during the screwing operation (that is, the axial direction of the first cylindrical portion 31A) or in a direction within a predetermined range based on the traveling direction. It is a position where the extending directions of 51C are matched. In other words, the maintenance lever position refers to, for example, a cylindrical virtual region on an extension line in the axial direction that is obtained by projecting the first cylindrical portion 31A in the axial direction, and the lever main body 51 has a first position in the virtual region. 3 is a position where the operation lever 50 is operated so that all or most of the extending portion 51C exists. In other words, the maintenance lever position is a position where the operation lever 50 is not brought into contact with the feeder main body 10 or the other dispensing device 20 when the first cylindrical portion 31A is rotated around the axis. is there.

Support 52 of the present embodiment, the second facing portion 52c and a third face portion 52d opposed to the opposing portion 32a ₁ when the operating lever 50 is operated in the opposite direction from that at the time of opening operation from the closed when the lever is located (FIG. 3). That is, the second opposing portion 52c and the third opposing portion 52d are formed on the side opposite to the fulcrum portion 52b when viewed from the first opposing portion 52a in the respective side wall portions 52A. The third facing portion 52d is formed between the first facing portion 52a and the second facing portion 52c. In this illustration, the side connected to the side opposite to the fulcrum portion 52b of the side forming the first counter portion 52a is formed as the third counter portion 52d, and the first counter portion of the side forming the third counter portion 52d is formed. The side connected to the opposite side to 52a is formed as the second facing portion 52c.

The second opposing portion 52c is between the site of the support 52 opposite to the opposing portion 32a ₁ of the first opposing portion 52a until switched to the second opposing portion 52c, member interlocked with the shaft member 42 or the shaft member 42 To a shape in which a pressing force is not applied to the inner wall surface of the internal space of the housing 30. For this reason, in this support body 52, also about the 3rd opposing part 52d, it is the shape where a pressing force is not applied with respect to the inner wall face of the internal space of the housing | casing 30 from the shaft member 42 or the member interlock | cooperating with the said shaft member 42. Form. Here, the member interlocked with the shaft member 42 refers to the elastic member 43B, the seal member 44, the valve body 41, and the like. The inner wall surface of the internal space of the housing 30 refers to the inner wall surface of the internal flow path 34.

The third counter unit 52d, the operation lever 50 is formed so as to face the target facing portion 32a ₁ when the maintenance time of lever position. That is, the third counter unit 52d, when facing the target face portions 32a _1, the traveling direction (the axial direction of the first cylindrical portion 31A) of the housing 30 during screwing operation for the feeder body 10 or The third extending portion 51 </ b> C of the lever main body 51 is formed so that the extending direction thereof coincides with a direction within the predetermined range based on the traveling direction. Thus, the operation lever 50, by the third opposing portion 52d is rotated to a position opposed to the opposed portions 32a _1, during screwing work of dispensing device 20, the supply unit 10 and the other lever body 51 It can hold | maintain in the position which does not contact the extraction apparatus 20 of this. For this reason, this pouring device 20 can be easily screwed into the feeder main body 10 and can improve maintainability.

  In the dispensing device 20 of the present embodiment, when it is assumed that the support body 52 does not have such a second facing portion 52c, the operation lever 50 is operated from the closed lever position in the opposite direction to the opening operation. When the operation is continued, a pressing force is applied to the inner wall surface of the internal space of the housing 30 from the shaft member 42 or a member interlocking with the shaft member 42, for example, at the maintenance lever position or more than the maintenance lever position. The operation lever 50 does not move any more after being moved a little (FIG. 7). At that time, a new fulcrum portion 52e is generated on the support body 52, and a portion where the pressing force acts becomes an action point portion. For this reason, when the operation lever 50 continues to be operated in the same direction, there is a possibility that the durability of the dispensing device 20 such as the first lid member 32 being detached due to the pressing force is reduced. Further, along with a decrease in durability, etc., there is a possibility that the beverage is leaked to the outside even though the lock mechanism 60 is in the locked state. That is, the pressing force can be said to be a useless load for the dispensing device 20.

However, since the support body 52 has the 2nd opposing part 52c and the 3rd opposing part 52d which were mentioned above in the extraction | pouring apparatus 20 of this embodiment, the operation lever 50 is the time of opening operation from the lever position at the time of closure. when continued to be operated in the opposite direction to the such without causing unnecessary load to become pressing force, the second site of the support 52 opposite to the opposing portion 32a ₁ of the first opposing portion 52a The operation lever 50 can be moved while switching to the facing portion 52c (FIG. 8). In other words, the dispensing device 20 of the present embodiment can extend the rotation range of the operation lever 50 without generating a pressing force that becomes an unnecessary load. Therefore, even if the operation lever 50 is operated in the direction contrary to the intention at the time of design, the dispensing device 20 avoids a situation in which durability is deteriorated because no unnecessary load acts on each part. It is also possible to avoid leakage of the beverage product to the outside.

Here, the operation lever 50 has a second facing portion 52c and the opposing portion 32a ₁ is also possibly be further operated from the state facing. Accordingly, the second facing portion 52c, when part of the support 52 opposite to the opposing portion 32a ₁ is then switched to the second opposing portion 52c, which are operated further operating lever 50 in the same direction as during the switch, It is desirable to form the lever main body 51 in contact with the feeder main body 10 before the pressing force is applied to the inner wall surface of the internal space of the housing 30 from the shaft member 42 or a member interlocking with the shaft member 42. The second facing portion 52c of the present embodiment causes the lever main body 51 to abut against the front panel 12a before the pressing force is applied (FIG. 8). Thereby, since the extraction | pouring apparatus 20 of this embodiment can suppress generation | occurrence | production of the pressing force used as a useless load as much as possible, avoiding a fall of durability and the leakage of the drinks outside appropriately. Can do.

  In the dispensing device 20 of the present embodiment, even when the operation lever 50 is further pushed from the opened lever position, the same event as that in the case where the support 52 does not have the second facing portion 52c. Can happen. However, in the pouring device 20 according to the present embodiment, when the operation lever 50 is further pushed from the open lever position, the operation lever 50 comes into contact with the rear wall 16a of the pouring chamber 16, and no more operation levers. Since the rotation of 50 is restricted, a situation that causes a decrease in durability is avoided. However, when such a rear wall 16a is not provided, it is desirable to form a facing portion similar to the second facing portion 52c on the support body 52 to reduce durability. The facing portion is a portion in which a fulcrum portion 52b is formed on one end side.

  As described above, the beverage supply machine 1 and the dispensing device 20 of the beverage supply machine 1 according to the present embodiment can suppress a decrease in durability due to an erroneous operation on the operation lever 50 by the user. For this reason, the beverage dispenser 1 and the dispensing device 20 of the beverage dispenser 1 have the beverage product outside due to an erroneous operation, even though the lock mechanism 60 is activated (locked). Can be avoided.
