Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a mounting structure for a coin wrapping section in a coin wrapping machine that automatically stacks a predetermined number of coins and wraps them with a wrapping sheet. .

(Prior Art) As is conventionally known, this type of coin wrapping machine stacks a predetermined number of coins supplied from a coin supply section equipped with a coin passage and a coin counting means in a stacking section, and then stacks them in a stacking section. In the packaging section, the accumulated coins are wrapped with a packaging sheet. The packaging section of this coin wrapping machine is, for example,
As shown in Japanese Patent Publication No. 20493 and Japanese Patent Application Laid-Open No. 50-31984, a rotary member composed of a plurality of rollers, etc. driven by a drive device is rotated around a stack of coins guided inward. The packaging sheet is placed between the rotating member and the circumferential surface of the accumulated coins, and the rotating member is rotated to wrap the packaging sheet around the accumulated coins. Both sides of the packaging sheet are crimped with crimping nails.

Furthermore, in a separate application filed by the applicant,
In order to make the coin wrapping machine smaller and lighter, we have proposed an accumulating and packaging device for a coin wrapping machine that uses a belt to serve as both a coin accumulating section and a wrapping section. That is, this device has a belt of a predetermined width above and below, which is stretched between a pair of main rollers and a guide roller that are arranged parallel to each other at a predetermined interval, and is bent from between the pair of main rollers. A cylindrical coin storage chamber is formed by the curved portion, and a back-up roller that maintains the shape of the coin storage chamber is arranged on the back side of the belt in the coin storage chamber forming portion, and
A coin support part that supports the coins accumulated in the coin storage chamber and caulking claws that caulk both upper and lower edges of the packaging sheet that is fed into the coin storage chamber and wrapped around the accumulated coins are provided, A packaging section that also serves as a stacking section is configured so that coins are stacked in the storage chamber and the stacked coins are wrapped with a packaging sheet.

By the way, in this type of coin packaging machine, the members constituting the packaging section are attached to a frame etc. fixedly provided inside the packaging machine body, and are installed at a predetermined position inside the packaging machine body. As a result, there were inconveniences in maintenance and removal of the packaging sheet in the event that a jam occurred in the packaging section where the packaging sheet was not properly wrapped and jammed. In particular, in the case of a structure in which coins are accumulated and packaged in a hollow cylindrical coin storage chamber formed by using a bed, the accumulated coins are Since most of the periphery is surrounded, simply attaching it to a fixed frame within the packaging machine body will make it extremely difficult to remove the packaging sheet when a jam occurs in the coin storage chamber.

(Object of the Invention) In view of the above-mentioned circumstances, the present invention provides a packaging section mounting structure in a coin packaging machine that can simplify the work of removing the packaging sheet when a jam occurs in the coin packaging section and the maintenance.

It is connected to the portion 37b via an arm 46.

When the cam 31 rotates due to the denomination setting operation, the lever 34 and movable block 37 swing, causing the guide roller 13 to move and each guide roller 18 to move accordingly. Accordingly, the coin storage chamber 16 expands and contracts to obtain a diameter that corresponds to the denomination of the coin.

Furthermore, the bracket 38 is attached to the movable block 37 so as to move the guide roller 13 in the direction of reducing the coin storage chamber 16 and bring the belt 15 into close contact with the coin during coin packaging. The solenoid 48 is rotatably mounted thereon and connected to the solenoid 48 .

A support frame 50 that supports the main part of the coin wrapping section 7 is formed by connecting upper and lower support plates 51 and 52 with a plurality of connecting rods 53. This support frame 50 is constructed such that one side of the front portion of the packaging machine body 1 located near the door 54 is pivotally supported via a vertical shaft 56 by a fixed frame 55 of the packaging machine body 1. Centering on the shaft 56, there is a storage state in which the entire body is located within the packaging machine body 1 (the state shown in FIG. 3), and a state in which the majority (at least the portion including the coin storage chamber 16) is located outside the packaging machine body 1. It can be moved to the open state (the state shown in FIG. 7).

Between the other side of the front portion of the support frame 50 and the packaging machine main body 1, a removable locking portion is provided to maintain the storage state. This locking portion consists of a locking convex portion 59 provided on a protrusion 58 that projects laterally from a fixed frame 57 of the packaging machine main body 1, and a key-shaped locking portion rotatably attached to the support frame 50. When in the stored state, the locking piece 60 is urged by a spring 61 and is locked to the locking protrusion 59.

Normally, as shown in FIG. 3, the entire packaging section 7 is kept housed in a predetermined position within the packaging machine body 1, and coins are packaged in this state. In this case, according to the structure of the packaging section 7 which also serves as a stacking section as in the present embodiment, when the coins are stacked, the positions of the guide roller 13 and the backup roller 18 are adjusted in advance by the denomination setting operation. While the coin 10 is fed into the storage chamber 16, both the main rollers 11 and 12 are driven synchronously. As a result, the coin storage chamber 16 rotates while maintaining a constant shape with a diameter corresponding to the denomination of the coin 10,
In other words, the concave portion of the belt constituting the coin storage chamber 16 moves in the circumferential direction while being pressed against the back up roller 18, and this action applies rotational force to the coin, preventing the coin from standing up and allowing the coin to move. Accumulated.

After stacking, the stacked coins are supported at a predetermined height position within the coin storage chamber 16, and the peripheral wall of the coin storage chamber 16 is brought into close contact with the stacked coins by the operation of the solenoid 48. in,
The packaging sheet 9 is introduced from the packaging sheet introduction opening 17, and the main roller 11 is driven. As a result, while the packaging sheet 9 is sandwiched between the accumulated coins and the peripheral wall of the coin storage chamber 16, the coin storage chamber 16 rotates (the belt 15 moves in the circumferential direction).
The coins are rotated, and the wrapping sheet 9 is wrapped around the accumulated coins. Thereafter, both upper and lower sides of the packaging sheet are crimped by the crimping claws 68 to complete the packaging.

If a jam occurs in which the packaging sheet is jammed during such a wrapping operation, the support frame 50 and the main part of the packaging section attached to it are placed in the open state shown in FIG. Removal work etc. can be done easily. That is,
In such a case, after opening the door 54 of the packaging machine main body, operate the locking piece 60 to release it from the locking protrusion 59, and then move the support frame 50 forward about the vertical axis 56. By moving the support frame 50 and the main roller 1 supported thereto,
1, 12, guide rollers 13, 14, back-up roller 18, a portion of the drive mechanism, a portion of the position adjustment mechanism, etc. move forward and outward of the packaging machine main body 1.
Therefore, in this state, the packaging sheet can be easily removed from the top and bottom of the coin storage chamber 16 or from the opening 17 for introducing the packaging sheet.

Also, after such work, the support frame 5
0 toward the inside of the packaging machine main body 1, it can be easily returned to its original storage state, and at this time, the stopper 62 correctly determines the position at the time of storage.

(Effects of the Invention) As described above, the present invention has a belt that is wrapped around a pair of main rollers and a guide roller and is bent from between the pair of main rollers, and the coin is formed by the concave portion of the belt. A packaging unit is provided in which coins are accumulated and packaged in a storage chamber, the main part of the packaging part is supported by a support frame, and the support frame and the main part of the packaging part are connected around a vertical axis.
It is movable between a storage state in which the whole body is located inside the packaging machine body and an open state in which at least the coin storage chamber 16 is located outside the packaging machine, and a detachable lock is provided between the support frame and the packaging machine body. Since the device is provided, the above-mentioned coin storage chamber is formed with a belt, making it an advantageous structure for downsizing the packaging machine, etc., and when a jam occurs in the above-mentioned coin storage chamber, it can be easily removed from outside the packaging machine main body.
