BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a bag dispensing apparatus for dispensing a bag, which is installed in a vending machine or the like and is configured to provide a bag used for conveying goods sold in the vending machine.

Conventionally, this type of vending machine, especially in vending machines for sale of ice cream, etc., is difficult to catch the product, so as described in Japanese Patent Application No. 3-312575, which was filed by the Applicant, for the simultaneous discharge of the product. It is configured to provide a bag of.

Such a bag is loaded into a plurality of vending machines, and one piece of the bag is sent out each time the product is sold by the rotation of the delivery roller, and the buyer takes the discharged ice cream into the outgoing bag.

Such a bag conveying apparatus faces the above rollers from the wall of the main body into the main body, and the encapsulated and stacked bags are pushed to the rollers at a predetermined pressure by a compression plate to create a friction force between the rollers and the bags. It is configured to send.

The compression plate of the bag delivery device pushes the bag toward the roller, but at the same time, the force pushing the bag to the main body wall surface where the roller is present is exerted.

When the bag is pushed to the main body wall surface by the compressive force from the compression plate on the discharge side of the roller, the roller becomes a form for sending the bag to this compressed part. Therefore, the bag is bent in a zigzag shape due to the flexibility of the bag. As the bag dries on the roller.

Therefore, there was a problem that it could not be inserted between the roller and the main body wall surface and sent out of the main body.

In addition, when replenishing a bag in a conventional bag delivery device, the compression plate was spaced apart from the roller with one hand, and the bag was filled between the roller and the compression plate with the other hand.

However, such a method has a drawback in that it is difficult to fill the bag by the flexibility of the bag because it must be loaded with bags stacked with one hand, and workability is significantly complicated.

The present invention has been made to solve such a conventional technical problem, and an object of the present invention is to provide a bag dispensing apparatus capable of preventing a bag from rolling in a roller and smoothly dispensing the bag.

Another object of the present invention is to provide a bag delivery device that facilitates the filling operation of the bag.

That is, the bag delivery device 1 of the present invention of the present invention comprises a roller 11 for delivery from the wall surface 14 of the main body 9 into the main body 9, and a bag loaded in the main body 9 ( In the bag dispensing apparatus 1 which has the compression means for compressing B) to the said roller 11, and delivers the bag B by the rotation of the roller 11, the said compression means is said bag. The compression member 12 which abuts the other surface of the said bag B in the range which the one surface of (B) abuts on the roller 11, and the compression member 12 said bag B mentioned above And one end of the compression member 12, which is made up of the pressing members C1 to C4, which are positioned in the dispensing direction of the bag B, than the other end. 14).

Moreover, the bag conveying apparatus 1 of this invention of Claim 2 is equipped with the roller 11 for sending, and the compression means which compresses the bag B to the said roller 11, The rotation of the roller 11 is carried out. In the bag delivery device (1) for delivering the bag (B), the compression means includes a compression member (12) contacting the bag (B) and a compression member (12) for compressing the bag (B). To the releasing member 13 for applying the force to hold the compression member 12 apart from the roller 11 against the force applied by the pressure members C1 to C4 and the pressure members C1 to C4. It is made up.

According to the bag delivery device 1 of the present invention described above, the compression plate 12 of the compression means compresses the bag B by coil springs C1 to C4, and the bag B is compressed. It is compressed to the roller 11 by the compressive force from the board 12.

When the roller 11 rotates in this state, the bag B is discharged by the frictional force with the roller 11, but at this time, one end of the compression plate 12 located in the dispensing direction of the bag B is more than the other end. Since it is spaced apart from the front wall 14 of (9), the bag B is not compressed by the front wall 14 of the main body 9 at the feeding side of the roller 11, and becomes freely movable. have.

Therefore, the bag B is sent out smoothly by the rotation of the roller 11, without being restrained on the feeding side of the roller 11.

In addition, according to the bag delivery device 1 of the present invention, the compressed wave 12 can be held apart from the roller 11 by the lock lever 13 when the bag B is loaded. Both hands can be used to load the bag 12 at the interval between the roller 11 and the compression plate 12.

Side view of the bag delivery device 1 showing (C2) in solid line, FIG. 4 is a front view of the bag delivery device 1, and FIG. 5 is a view of the vending machine 2 as an embodiment provided with the bag delivery device 1. Front view.

In FIG. 5, the product outlet 4 is formed in the front outer door 3 of the vending machine 2, and the product outlet 6 shown in FIG. 7 is located behind the product outlet 4. Consists of.

In the upper part of this product taking-out chamber 6, the transparent door 7 hangs freely, and the upper end hangs freely, and the opening and closing of the front product taking-out port 4 is closed freely.

At the rear of the door 7, a plate 8 for preventing mischief made of a metal plate is provided in the same shape as the door 7, and the upper end thereof is freely hung by rotation.

When the door 7 is opened as shown by the dotted line in the figure, the plate 8 is pushed backward in the same shape as shown by the dotted line, and extends to the rear part in the product taking-out chamber 6 to the rear vending machine mechanism. Preventing mischief

The bag dispensing apparatus 1 of this invention is attached to the inner surface of the outer door 3 of the left side of this product taking-out chamber 6.

The bag conveying apparatus 1 includes the main body 9, the roller 11, the compression plate 12 as the compression member, the coil springs C1 to C4 as the pressure member to apply the force, and the pressure release member. It is composed of a lock lever 13 as a.

The main body 9 consists of a front wall 14 composed of a metal plate, left and right side walls 16 and 17 and a rear wall 18 facing the lower portion of the front wall 14, It is open upward, and a hanging bar 19 protrudes rearward and is attached to the upper end of the front wall 14.

In addition, the lower part of the front wall 14 facing the rear wall 18 of the main body 9 is provided with a slit-shaped transmission hole 21 on the left and right, and a roller 11 is provided therein, part of which is the main body. (9) We are facing me.

These rollers 11 are attached two to the left and right through the roller clutch 24, respectively, on the rotating shaft 23 of the gear motor 22 as drive means, and are comprised as a raw material with a large friction coefficient on the surface.

The roller clutch 24 transmits the driving force of the rotating shaft 23 to the roller 11 only when the rotating shaft 23 rotates in the clockwise direction during the first rotation, and the roller (with the rotating shaft 23 stopped). When only 11) rotates in the clockwise direction in the first direction, the coupling between the roller 11 and the rotating shaft 23 is blocked, so that only the roller 11 freely rotates.

The compression plate 12 is made of a metal plate and is provided opposite the roller 11 described above inside the front wall 14 of the main body 9.

The compression plate 12 has a dimension of the width that can be spanned between the left and right side walls 16 and 17 of the main body 9 and has a dimension of the upper and lower predetermined ranges including the portion P which abuts with the roller 11. The support shaft which consists of the contact part 26 and the upper and lower flanges 27 and 28 bent continuously back and forth from the upper and lower ends of this contact part 26, and is attached to the upper end of the back side of the contact part 26. The sliding of the 29 to the guide holes 31 and 31 in the front and rear directions formed on the left and right side walls 16 and 17 of the main body 9 is supported by the main body 9 while being freely engaged.

The coil springs C1 to C4 are the same coil springs and have the same elastic force.

The coil springs C1 and C4 are bent to form a bow shape with the apex at the lower side at the left and right sides between the compression plate 12 and the rear wall 18, and the front end of the coil spring C1 and C4. 29), and the rear end is fixed to the front upper part of the rear wall 18.

The coil springs C2 and C3 are bent inside the coil springs (C1) and C4, and this time bent so as to have a bow shape with the upper end apex, the front end of which is in contact with the compression plate 12 ( It is fitted to the left and right shaft 32 attached to the lower rear side of the rear surface 26, and the rear end thereof is fixed to the lower front surface of the rear wall 18.

Each coil spring C1-C4 is attached so that the compression plate 12 may bend at least 90 degrees in the state which the compression plate 12 abuts on the roller 11 like FIG.

Such coil springs are known to exhibit a substantially constant repulsion force, particularly at bending angles of 90 degrees or more.

Therefore, the coil springs C1 to C4 each have the same compressive force B as the amount of the bag B loaded between the roller 11 and the compression plate 12 increases and decreases so that the distance between them changes. ) Can be added.

Moreover, as shown in FIG. 2 and FIG. 3, the distance L1 from the part P which abuts on the roller 11 of the compressed plate 12 mentioned above to the support shaft 29 is from the part P which abuts. It is comprised so that it may become larger than the distance L2 to the axis | shaft 32. FIG.

As a result, when the compression is performed with the same force by the coil springs C1 to C4 in relation to the moment, the compression plate 12 is rotated in the counterclockwise direction in the second direction about the abutting portion P. You will be strengthened.

As a result, the upper end of the contact portion 26 of the compression plate 12 is in a state of being close to the front wall 14 of the main body 9, and the lower end thereof is separated from the front wall 14, thereby compressing the plate 12. Is inclined with respect to the front wall 14.

The lock lever 13 described above is inserted into the main body 9 from the penetrating hole 33 bored in the rear wall 18, and the tip thereof is installed at approximately the center of the rear surface of the contact portion 26 of the compression plate 12. Rotation is freely attached to one shaft 34, and the rear end thereof projects rearward from the transmission hole 33. As shown in FIG.

Moreover, the cutout part 36 is formed in the lower surface of the intermediate part of the lock lever 13. As shown in FIG.

The bag dispensing apparatus 1 of this structure is attached to the back surface side of the outer door 3 by the attachment hole 41 so that the front wall 14 may correspond to the back surface of the outer door 3 of the vending machine 2. have.

At this time, as shown in the perspective view of FIG. 6 (a view through the outer door 3), the bag dispensing apparatus 1 has the hanging bar 19 side on the upper left side and the compression plate 12 side on the product taking out chamber. Tilt it about 45 degrees in the form corresponding to the left side of (6), and attach.

The left side wall 6A of the goods taking-out chamber 6 is formed with the slit-shaped outlet 42 up and down behind the board 8, and the lower end of the bag delivery device 1 is this outlet 42 ) Is opposed to the upper left slope.

Next, operation | movement of the bag sending apparatus 1 is demonstrated.

First, when filling the bag B for transport into the bag delivery device 1, the outer door 3 of the vending machine 2 is opened, and then the lock lever 13 is moved to the coil springs C1 to C4. 2) The cutting portion 36 formed on the locking lever 13 is hooked to the end surface of the through hole 33 drilled in the rear wall 18 as shown in FIG.

As a result, the compression plate 12 is kept in a state separated from the roller 11, so that the bag B can be loaded by a maintenance worker using both hands.

The bag B is, for example, a bag made of reinforced polyethylene having a length dimension of about 310 mm. A hole (not shown) is drilled in the upper part, and the tip is inserted between the compression plate 12 and the roller 11, and the hole described above. It is inserted in the hanging rod 19 and loaded in a state where a plurality of sheets are stacked as shown in Fig. 8, but since it is flexible, it is difficult to load with one hand.

Conventionally, the loading operation was very complicated because the compression plate 12 was loaded with the other hand while pressing the compression plate 12 with one hand. However, the present invention provides the compression plate 12 by the locking lever 13 in the bag delivery device 1. ) Can be removed from the roller 11 and can be charged using both hands, so that the loading operation can be performed extremely smoothly.

In addition, as shown in FIG. 7, since the door 7 and the plate 8 are suspended from the upper side in the product outlet 4, the bag dispensing device 1 can be attached to the upper side of the product outlet 4; none.

For this reason, if the bag delivery device 1 is attached to the side of the product outlet 4 sideways and attached, the bag B is inserted from the side when the bag B is loaded, but the bag B is smooth and downwards with gravity. This insertion work is very difficult because it is going to be bent.

However, by attaching the bag dispensing device 1 inclined as in the embodiment, the tip of the bag (B) is left to gravity and can be inserted between the compression plate (12) and the roller (11) in a state of hanging down. This is done very easily.

After filling the bag B in this manner, the locking lever 13 is lifted up and the cutout portion 36 is removed from the through hole 33. The locking lever 13 is formed by the repulsive force of the coil springs C1 to C4. The part 26 which is pulled back into the main body 9 and the compression plate 12 abuts contacts the back surface of the outermost bag B as shown in FIG. 1 so that the innermost bag B is roller 11. To compress.

At this time, as described above, the upper end of the contact portion 26 of the compression plate 12 is close to the front wall 14 of the main body 9, the lower end of the compression plate 12 in a state separated from the front wall 14 ) Is inclined with respect to the front wall 14, so the innermost bag B is compressed to the roller 11 and at the same time the front wall 14 at the top of the roller 11 corresponding to the upper end of the abutting portion 26. At the lower end portion of the roller 11 in the feeding direction of the roller 11, it is separated from the front wall 14 as shown in FIG.

When hardening | curing is input by a purchaser and ice cream as a product is selected, the vending machine mechanism not shown in the inside of the vending machine 2 discharges a product to the goods taking-out chamber 6.

In conjunction with this discharge operation, a control circuit (not shown) drives the gear motor 22 for a predetermined time, and rotates the roller 11 in the clockwise direction in the first drawing. The innermost bag B is moved toward the lower outlet 42 by friction between the rollers 11, pulled away from the hanging bar 19, and fed about 80 mm in one selling operation. .

At this time, the bag B is not compressed to the front wall 14 on the discharge side of the roller 11 at the lower side, and thus the bag B is freely moved. It is sent out smoothly without staying on the sending side.

Therefore, the problem that the bag B is wound around the roller 11 and sandwiched between the roller 11 and the front wall 14 like the conventional one can be solved.

As a result, the lower end of the bag B protrudes from the outlet 42 into the product taking-out chamber 6 as shown in Fig. 6, so that the purchaser pushes the door 7 and the plate 8 to open it. When the bag B is taken out at the same time when the goods in the goods taking-out chamber 6 are taken out, the roller 11 rotates idlely by the roller clutch 24 as mentioned above about the direction, and the bag B is sealed by the bag delivery device ( It can be taken out easily from 1).

When the bag B is gradually sent out by this operation, the compression plate 12 approaches the roller 11 so that the distance between the roller 11 and the compression plate 12 decreases, but the coil spring C1 as described above. Since (C4) exhibits a substantially uniform repulsion force regardless of the change in this distance, the compression plate 12 pushes the bag B to the roller 11 at a substantially constant pressure regardless of the change in the quantity of the bag B. To compress.

Therefore, even if the number of sheets B changes, the friction force between the roller 11 and the bag B becomes substantially constant, and feeding is performed smoothly.

In addition, the bag dispensing apparatus 1 does not send out the whole bag B at the time of one product sale, but in an Example, it only stops sending out about 1/4 of 80mm, and it removes by a buyer after that. have.

Therefore, the roller 11 is prevented from feeding out to the upper end of the bag B which is most easily wound on the roller 11, and the winding of the bag B to the roller 11 is prevented as much as possible.

Furthermore, depending on the purchaser, the bag B may be unnecessary. In that case, the bag B sent out remains in the state shown in FIG. .

That is, when the bag B is not pulled out in one sale, the same bag B is sent out again without sending the next bag B, so that wasteful discharge of the bag B can be prevented. have.

In particular, since the bag B protrudes into the goods withdrawal chamber 6 from the rear of the plate 8, even if it is not removed by the purchaser in the dispensing state and remains as shown in FIG. do.

Therefore, it is possible to prevent mischief from removing the bag B in this state except for the purchaser.

In addition, although the embodiment described the manner in which the repairman peels off the engagement of the locking lever 13, the present invention is not limited thereto, and the rear end of the locking lever 13 is closed by closing the outer door 3 of the vending machine 2. The main body of the vending machine 2 may be configured to be peeled off automatically.

In the embodiment, the coil springs C1 to C4 are configured to be the same, and the inclination with respect to the front wall 14 of the compression plate 12 is changed by the positional relationship between the roller 11 and the compression plate 12. Although it comprised, it is not limited to this, For example, you may make upper coil spring C2 (C3) stronger than lower coil spring C1 (C4), and comprise the inclination of the compression plate 12.

However, since the coil springs (C1) to (C4) can be made of the same component in the same manner as in the embodiment, it is advantageous in terms of parts management, and also there is an advantage in that no assembly error occurs.

In addition, in the embodiment, although the bag dispensing apparatus 1 of this invention was applied to the vending machine 2, it goes without saying that it is effective for the various apparatuses which provide bags.

As described in detail above, according to the invention of claim 1, one end of the compression member located in the dispensing direction of the bag is spaced apart from the main body wall surface than the other end, and the encapsulation on the dispensing side of the roller is not compressed to the main body wall surface. Since the bag is freely movable, the bag can be smoothly discharged by the rotation of the roller without staying on the feeding side of the roller, thereby preventing occurrence of a failure such as curling to the roller.

In addition, according to the invention of claim 2, since the compression member can be held apart from the roller by the force release member applied at the time of loading the bag, it is possible to load the bag at a distance between the roller and the compression member using both hands. As a result, the reloading operation of the bag can be achieved very smoothly.
