The main stopper (1 (1) of the cylinder is extended and supported approximately horizontally into the product passage (7), and is retracted from the lower part of the main stopper aυ on the other product passage (7) side, so that the product passage (1) of the main stopper α1) is 7) It is configured to release the inward extending support. α Gloss is the main stopper when the IQ (11) is placed and supported on the control member (9). One end is locked to the main stopper 00) αυ, and the other end is abutted and locked to the control member (9) so that αI (11) is urged upward by an elastic force that overcomes the load of one product to be sold and sent out. When the main stopper θ0IQII is rotated to a predetermined position above the horizontal position supported by the control member (9) due to the elasticity of the sold-out detection spring, the main stopper <(101(10) The sold-out detection switch Q, 11 (+3) is activated by The product is configured so that the product is sold out when the switch α4 is operated. One end of α4 is locked to the main stopper (101 (1υ), and the other end (14
A) is a delivery spring having stronger elasticity than the sell-out detection spring (12) inserted into the elongated hole (9a) of the control member (9), and normally the end (14a) is inserted into the elongated hole (9a). The control member (9) is kept in a free state so as not to develop elasticity within the control member (9).
When main stopper a [αυ] is released from support due to the retraction movement of main stopper a [αυ], the end portion (14a) is locked to the end of the elongated hole (9a) and is locked to the upper surface of the control member (9), so that it becomes elastic. The main stopper 00 was released from its support and hung down.
(11) is configured to forcefully rotate the product passage (force) outward against the elasticity of the sold-out detection spring 03.aω(16)it, rotate the upper end It is freely pivoted and the locking part (171) at the lower end is an auxiliary stopper that can move in and out of the product passage (force). The base material (4)
The auxiliary stoppers αω are provided on both sides of the upper part.
The locking cam (18a) provided on the drive shaft (5) corresponding to the locking cam (1 to 1) controls the locking portion to move into and out of the product passageway (7). For cam 0 rare, electric motor (6
) is rotated by the rotation of the drive shaft (5) driven by the main stopper (101 (11)), and is pressed against the auxiliary stopper (151 (161') to move the locking part 0η to the product path. (It is made to protrude into force (7).

Next, the operation of the above configuration will be explained. Delivery cam (8
) is located so that the driving part (8a) protrudes forward, and the control member (9) supports the main stoppers (IQ) (11) on both sides, respectively, and extends the product passageway (7) (approximately horizontally into the force). Each main stopper (101 (lυ) has a product (5
) are piled up and stored. In addition, the locking cam (1 rare drive part (18a) is located at the rear of the drive shaft (5) in the middle of the auxiliary stoppers (15) (IG) on both sides, and therefore each auxiliary stopper (151 (16) The locking part 0η of is the product aisle (
It is located 7 baka outside.

This state is a sales delivery standby state and is shown in FIGS. 6 and 7.

When a predetermined amount of money is inserted and a predetermined operation related to sales is performed during this sales sending standby state, a sales sending command is sent to the electric motor (6), and the electric motor (6) drives the drive shaft (
5) is rotated 180 degrees in the direction of the arrow in FIG. 7 and then stopped. This rotation of the drive shaft (5) causes the drive part (18a) of the square locking cam (1 to 1) to move the delivery cam (8).
) to release the support of the main stopper (11) on the product delivery side, the auxiliary stopper 06) is pressed to cause the locking portion 0η to protrude into the product path (force), and press and lock the product (All). On the other hand, due to the rotation of the drive shaft (5), the delivery cam (8) is also rotated, and as the delivery cam (8) rotates, the delivery cam (8) is pressed against the control part (9C) of the control member (9). , drive unit (8
c) to the drive section (8a). Therefore, due to the shape of the delivery cam (8), the control member (9) is controlled by the delivery cam (8).
) in the direction of the arrow in FIG. 6 is small at the beginning of the rotation of the drive shaft (5), and increases as the drive shaft (8a) approaches the middle stage of rotation by 90 degrees. When the end of the control member (9) reaches the vicinity of the shaft support of the main stopper (lυ), the end (14a) of the withdrawal spring 04 is locked to the end of the elongated hole (9a) of the control member (9). When the end of the control member (91) releases the support of the main stopper (111), the main stopper O11 is suddenly rotated downward due to the elasticity of the spring 141 and the load of the product (A). Product (A
, ) is sent out falling downward. This state is shown in Figures 8 and 9.
As shown in the figure.

When the drive shaft (5) further rotates, the main stopper QQ
The control member (9
) is rapidly returned in the direction of the arrow in FIG. 8 by the driving portion (8C) of the delivery cam (8), prior to the unlocking operation of the product (A3) by the auxiliary stopper (16).

Therefore, the main stopper (11) is pressed by the control member (9) into the product passage (force), and as the control member (9) moves, it extends into the product passage (force) and is placed and supported. At the beginning of the return movement of step 9), the sending spring (14) is released from the engagement with the end of the elongated hole (9a) of the end (14a) and becomes free within the elongated hole (9a). The main stopper aυ mounted and supported on the control member (9) is rotated above the horizontal position due to the elasticity of the sold-out detection spring (121), but until this state the drive shaft (5) When the locking cam (18) rotates, the driving part (18a) of the locking cam (18) releases the pressure on the auxiliary stopper (16), so that the locking part 07 of the auxiliary stopper rotates toward the product path (forcefully rotates outward). Then, the product (A,) is released from the lock.Therefore, the released product (A,) falls onto the main horn cutter under its own weight and resists the elasticity of the spring (1'1:I). main stopper Ql)
is rotated by the control member (9) to a horizontally supported position and locked. Then, the drive shaft (5) finishes rotating 180 degrees, the electric motor (6) stops, and the control member (9) is moved to the main stopper Q (101) on both sides by the delivery cam (8).
The one-sale delivery operation is completed in a state in which they are placed and supported in the same extended position on the lower surface of the machine, and the machine enters a standby state. This state is shown in FIGS. 10 and 11.

When the next sales sending command is delivered to the electric motor (6),
The delivery cam (8) moves the control member (9) in the direction of the arrow in FIG.
) to send out and sell. That is, each time a sales sending command is issued, the drive shaft (5) rotates 180 degrees to perform one sales sending operation.
Product aisles on both sides (power) products are sent out and sold alternately.

(F) Effects of the Invention Since the present invention has the above-described configuration, even when a product that is easily deformed such as a beverage product in a paper container is stored and locked, the lowest product will not be deformed due to the product load, and the quality of the product will be improved. No deterioration occurs. In addition, the forward and backward movement of the control member is controlled by a feeding cam formed in a substantially triangular shape, allowing the main stopper to slowly release the product from locking, and the main stopper to return quickly after sending out the product. , it is possible to send out products reliably.
