Description

The present invention relates to a vending machine with a microwave oven, and more particularly to a vending machine with a microwave oven, which is arranged so as to be partitioned between a product storage and a heating chamber having a microwave oven, and is used as a sales signal. The present invention relates to a structure of a product carry-out door that opens and closes based on the above-mentioned condition and carries a product (food) from a product storage to a microwave oven.

(B) Conventional technology Conventionally, a product carry-out door between a product storage and a heating chamber is normally sealed, and a product carry-out door that is opened at the time of sale to let a product pass is disclosed in Japanese Utility Model Publication No. 51-121099. As described above, it is generally found that the whole slides horizontally to open and close.

(F) Problems to be Solved by the Invention However, in the conventional device disclosed in the above publication, since the packing of the carry-out door slides on the surface of the partition wall during the opening / closing operation of the door, a large friction occurs. Since the packing is deteriorated by receiving the force and is moved in the lateral direction against the frictional force, a large torque drive motor is required to move the carry-out door. For this reason, the drive device for the carry-out door becomes large and complicated, and the storage space becomes large, and
There has been a problem that the storage function is deteriorated due to deterioration of the packing and the like, which causes the outside air to enter the storage, which adversely affects the storage condition of the product.

The present invention has been made in view of the above points, and provides an automatic vending machine with a microwave oven capable of opening and closing the carry-out door smoothly by reducing the power with a simple structure and preventing deterioration of the packing. To aim.

(D) Means for Solving the Problems The present invention is provided with a microwave oven equipped with a product carry-out door that opens and closes a product carry-out port that communicates between a product storage and a heating chamber having a microwave oven below the product store. In a vending machine, a product carry-out door support base supported so as to slide horizontally along a partition wall between a product storage and a heating chamber, and rotatably supported by the door support base by four links. , A product carry-out door mounted so as to be able to rise and descend horizontally, a door packing provided at the periphery of the product carry-out door, a drive device for the product carry-out door support base, and a direction in which the product carry-out door support base is closed. A stopper roller arranged to come into contact with the tip of the moving product carry-out door, and the product carry-out door support that slightly slides even after the stopper roller comes into contact with the product carry-out door And a switch means for switching the drive device to stop the drive device by the table, the product carry-out door contacts the stopper roller, and the product carry-out door support stand slides to move the product carry-out door upward when the link is rotated. The door packing is designed to be in close contact with the peripheral edge of the product outlet from the vertical direction.

(E) Work The product unloading door support is slid by a chain to move the product unloading door horizontally. During this horizontal movement, the packing on the peripheral edge of the upper surface of the product carry-out door does not slide on the partition wall surface between the product storage and the heating chamber. Therefore, it moves smoothly with a light force. Eventually, the product delivery door that came into operation touches the stopper roller, and further movement in the sliding direction is stopped. However, since the product carry-out door support base further slides, the link moves up so that the product carry-out door rises, and the packing comes into close contact with the periphery of the product carry-out port. Shield storage from outside air.

The present invention relates to the opening / closing structure of the in-compartment carry-out door 8 having the above-described configuration.

A description will be given below with reference to FIGS. 2 to 6. 30 is a partition wall that separates the product storage 3 from the heating chamber having the microwave oven 15.
As a base frame which is installed and fixed to the lower surface of 32, the whole has a shape of a downward opening in which left and right longitudinal side edges 30a, 30a are bent downward as shown in FIG. The reference rail 33b is located at the lower opening of the base frame 30, and the support rollers 34, 34, 34, 34 arranged on the left and right sides of the base frame 30 are provided inside the both sides 30a, 30a of the base frame 30. , 30b is slidably fitted,
The product unloading door support is mounted so as to slide back and forth. Further, reference numeral 36 is a product delivery door mounted on the product delivery door support base 33. Here, the product carry-out door 36 is attached to the product carry-out door support base 33 with four links 37, 37, 37, 37. That is, as shown in FIGS. 3 and 4, etc., door support shafts 38, 38 are arranged in front of and behind the product carry-out door support base 33, and the link 37, 37, 37, 37 is respectively attached to the door support shafts 38, 38.
The lower part of the link is pivoted, while the upper part of the link 37 ... is the product delivery door.
It is pivotally attached to shafts 39 ... Further, flanges 40, 40 are integrally formed on the lower edge of the link 37. As shown in FIG. 4 etc., the links 37 ... are normally in an upwardly inclined posture where the intersection of the bottom flange 41 and the side flange 42 is in contact with the door support base 33a, and the product delivery door 36 is held. Has been done. In this way, the product delivery door
36 is rotatably supported by the product carry-out door support base 33, and when the links 37 ... Rotate so as to rise upward, the product carry-out door 36 can perform an operation such that the entire product carry-out door 36 rises. At this time, the link
The bottom flange 41 of 37 acts to support the door support base surface 33a. 43 is a door packing attached to the peripheral edge of the back of the product delivery door 36.

By the way, as shown in FIGS. 2 and 6, a drive chain 44 is provided on one side of the base frame 30. The drive chain 44 is a drive motor 45 arranged and fixed at one end of the base frame 30.
It is installed between a drive gear 46 that is rotationally driven by and a driven gear 47 that is arranged separately from the drive gear 46. Then, the product carrying-out door supporting base 33 is coupled and attached to an appropriate portion of the drive chain 44 so that the supporting base 33 can reciprocate. For that purpose, the connecting plate 48 is fixed to one side of the product carrying-out door support base 33 by projecting and fixing, and the connecting plate 48 and the chain element 44 of the drive chain 44.
A and a are fixed with screws 49, 49. As a result, when the drive chain 44 moves rotationally, the product carry-out door support base 33 also moves accordingly. Since the drive motor 45 is capable of forward and reverse rotation, the product carry-out door support base 33 naturally moves freely in both the forward and backward directions by the forward and reverse conveyance of the drive chain 44. Then, the product carry-out door 36 mounted on the product carry-out door support base 33 is also integrally reciprocated via the links 37. A stopper roller 50 is provided at the front end of the base frame 30, and is a front end of the product carry-out door 36 that moves to close the product carry-out port 9.
Contact with 36a. Reference numeral 50a is a rotation supporting shaft of the stopper roller. Then, on the side opposite to the side where the drive chain 44 is provided in the base frame 30, the switch actuating pieces 51a, 52b hit the front and rear end edges of the moving product carrying-out door support base 33 to perform the switch operation. Micro switches 51 and 52 are provided. In the micro switch 51, the product delivery door
When 36 hits the stopper roller 50 and its movement in the sliding direction is stopped, and only the product carry-out door support base 33 is further slid slightly, it is operated by this support base 33 to stop the rotation of the drive motor 45. Has become. The product carry-out door 36 comes into contact with the stopper roller 50, and the product carry-out door 36 moves upward and the door packing 43 moves in the period until the product carry-out door support base 33 operates the micro switch 51 next time.
Will shield the peripheral edge of the product outlet 9. On the other hand, when the product delivery door 36 is opened, the micro switch 52
It is operated by the door support 33 to stop the rotation of the drive motor 45.

With the above-mentioned configuration, and the operation thereof will be described next, as shown in FIG. 6, the links 37 ... When the customer pushes the selection button 6 when a coin of a predetermined amount has been inserted from the state in which the product is in close contact with the periphery of the product outlet 9 and the product outlet 9 is closed for sale, the product is delivered by the sales signal. The mechanism operates to release the selected food 1 from the product storage 3. Drive motor at the same time
45 is driven, the drive gear 46 rotates, and the driven gear 47 causes the drive chain 44 to rotate leftward (arrow b). Therefore, the product carry-out door support base 34 is also moved in the same direction. Then, the links 37 ... Lower door support base shafts 38, 38 move in the same direction so as to rotate in the clockwise direction with the links 37 ... The packing 43 is separated from the lower edge of the product carrying-out port 9 to form a slight gap. The product carry-out door 36 moves to the left (arrow b) together with the door support 33 while keeping this gap, and there is no sliding between the door packing 43 and the partition wall 32, so that the product carry-out door 36 moves smoothly. To do. In this way, the product outlet 9 is opened, and the food 1 is stored in the product holder 10 through the product outlet 9. The product carry-out door 36 stops the drive motor 45 when the micro switch 52 is activated, and stops at that position. When the food 1 is received by the product holder 10, the first door body 23 starts sliding in the closing direction, and the food 1 is carried into the oven 16. Simultaneously with the operation of the first door body 23, the drive motor 45 reversely operates this time, and the drive chain 44 moves in the right direction (arrow a). This will support the product delivery door
33 also moves in the same direction, and as shown in FIG. 4, the product delivery door 36 moves while the links 37 ... Are tilted and the door packing 43 is not in contact with the partition wall 32. As a result, even when it closes, it moves smoothly without receiving frictional force with the partition wall 32. Then, as shown in FIG. 5, when the product carry-out door 36 comes directly under the product carry-out port 9, the front end thereof is the stopper roller 50.
Abut. However, the product carry-out door support base 33 is not in a condition in which the operation piece 51a of the micro switch 51 is sufficiently pressed to operate the switch, so the drive motor 45 continues to rotate, and the product carry-out door support base 33 is further Make a move. As a result, the horizontal movement of the door support shafts 38, 38 imparts a counterclockwise rotation action to the links 37 ... With the door support shafts 38, 38 as a fulcrum. Therefore, the upright rotation of the link 37 causes the product delivery door 36 to move in the vertical (upward) direction, and the door packing 43 comes into contact with the peripheral edge of the lower surface of the product delivery port 9 from the vertical direction and adheres thereto. The product delivery door 36 is lifted by the height stroke until the bottom flanges 41, 41 of the link 37 hit the door support base surface 33a, and the bottom flange 41 holds the standing state. In this way, the product carry-out door 36 first moves horizontally to a position directly below the product carry-out port 9, and then moves slightly upward, at which time the door packing 43 comes into close contact with the lower edge of the product carry-out port 9.
Therefore, the door packing 43 is remarkably less frequently in sliding contact with the partition wall 32 than the conventional one in which the door packing 43 is simply opened and closed in the sliding direction during the opening / closing operation of the door 36. Can be prevented from deterioration and durability can be increased. or,
Since the frictional resistance when opening and closing the door is significantly reduced, the product carry-out door 36 can be opened and closed sufficiently with a small motor with a small driving force, the structure is simple, the installation space of its drive parts can be reduced, and the overall size is small. It becomes the device of. Product export door 36
After the door is closed and the first door 23 is closed, the microwave oscillating device is activated, and the turntable 20 is also rotated to heat the microwave. After the microwave irradiation for a predetermined time, the second door body 27 is closed, the dielectric rod 11 enters the oven 16, and the food 1 on the turntable 20 is sold from the second opening 22 by its tip. Carry out to mouth 28. After the carry-out, the second door body 27 is closed and the dielectric rod 11 is also retracted to return to the standby state.

(G) Effect of the Invention As described above, according to the present invention, a product carry-out door that opens and closes a product carry-out port through which a product passes from a product storage to a heating chamber having a microwave oven is supported by four product carry-out doors. The product carry-out door is supported by a table, and when the product carry-out door support slides to the end position by sliding in the closing direction, the product carry-out door comes in contact with the stopper roller so that the product carry-out door is linked to the stopper roller. Rises due to
The door packing comes into contact with the product outlet surface from the vertical direction to shield the storage space.
Therefore, while sliding, the door packing does not slide on the partition wall surface between the storage compartment and the heating chamber, so that the deterioration of the door packing can be prevented and the frictional force associated with the sliding is small, so a large driving force can be applied. It is not necessary, and the door driving device can be composed of a small single motor, and the structure is simple and the cost is low, and the installation space can be reduced, and the entire opening / closing mechanism of the product delivery door can be downsized.
