Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to a double band reel mounting device for a packaging machine.

[Conventional technology]

In the conventional double band reel mounting device for a packaging machine, as shown in FIGS. , as shown in FIGS. 8A and 8B, are placed side by side at the same height. To explain why the double band reel mounting device is used in this way,
In particular, when the automatic packing machine 60 is installed between conveyor lines, the objects to be packed conveyed on the conveyor line are automatically stopped below the band guide arch of the automatic packing machine 60, After being banded and packed several times, they are transported to the next process on a conveyor line, but this packing work is automatically and continuously performed on the items to be packed as they are transported one after another. A reel unit 4 having a band reel 80 (FIG. 5) consisting of
Band coil 7 in which a band of 750 to 2000 m within 0 is made into a coil shape and sandwiched between the circular plates.
The 0 band gradually decreases and finally disappears. Then, it is necessary to pull out the band from a new band reel and feed it into the automatic packing machine 60, but since a commonly used packing machine has only one reel unit 40, the reel nut handle 47 must be connected to the reel shaft. , remove the reel-out circuit 45 , attach a new band coil 70 to the reel center drum, screw the reel nut handle 47 to the reel shaft via the reel-out circuit 45 , and then remove the band coil 70 . Pull out the band tip, pass it through several band guide rollers via the roller at the tip of the reel brake arm, and insert it into the band insertion port 61 of the automatic packing machine 60.
0 into the band guide arch. Therefore, it takes a relatively long time to attach the band coil 70 and set the band on the packaging machine in this way, and the packaging line must be stopped, especially if a large number of packaging operations are not performed automatically in succession. This will result in a large loss on the packaging line. Therefore, by providing two reel units 40 as described above, even if the band of the band reel 80 of one reel unit 40 runs out, the band coil 70 can be attached in advance. The band is pulled out from the other reel unit 40 and placed in the automatic packing machine 6.
It is possible to shorten the time by loading it into the 0.

[Problem that the idea aims to solve]

In the conventional double band reel mounting device for a packaging machine, the reel unit 40 is located high, making it difficult to mount the band coil 70. Nowadays, a large number of female workers are employed, so in such cases, there is a problem that the work is particularly hard for the female workers. For example, in an upper and lower double band reel device as shown in FIG. 7, the upper reel unit 40 is particularly high, and in a parallel device as shown in FIG. The band insertion port 6 of the automatic packing machine 60 is located approximately in the center between the outcircles 45.
Since the band guide rollers 24 are installed side by side so as to be located on a line opposite to the direction in which the bands are inserted into the band reel 80, the position of the band guide rollers 24 is adjusted so that the bands pulled out from the band reel 80 do not interfere with each other's band guide rollers 24. You need to move it up and down. Therefore, as shown in the figure, a pedestal is provided, a reel unit 40 is placed on the pedestal, and a band guide roller 24 is provided below the reel unit 40. Therefore, the mounting position of the band coil 70 becomes higher. Furthermore, in the conventional device, since the reel unit 40 is located high, two reel units 4
Since a stable elevated platform was required to install the 0, there was a problem in that the cost was high. Furthermore, in the parallel double band reel device as shown in FIG. 8, the two reel units 40 are installed side by side in the direction opposite to the direction in which the band is inserted into the band insertion port 61 of the automatic packaging machine 60, so the installation area is large. Moreover, since it was installed so as to protrude perpendicularly to the conveyor line, it also had disadvantages in terms of the layout of the workplace. Furthermore, in both the apparatuses shown in FIGS. 7 and 8, a band guide roller 24 for guiding the band pulled out from the band coil 70 to the band insertion opening 61 of the automatic packaging machine 60 is provided in each reel unit 40. In particular, it is necessary to provide more band guide rollers 24 for the reel unit 40 installed outside the band insertion port 61, and accordingly, it takes time to load the band. Furthermore, in the device shown in FIG. 7, it is necessary to provide the remaining band amount detection device 30 in each reel unit 40, and in the device shown in FIG. However, there are two set points inside the detection signal generating means 32, and as a result, it is necessary to set each point separately, resulting in problems such as high cost and cumbersome operation. Ta. The present invention allows the band coil 70 to be easily installed at a low position, reduces the installation area for parallel double band reels, allows quick band reel replacement, and has a simple structure and inexpensive packaging. The purpose of the present invention is to provide a mounting device for a double band reel in a machine.

In FIGS. 1A and 1B, the objects to be packed that are continuously conveyed on the conveyor line 62 are packed by the automatic packing machine 60 and conveyed to the next process. With this continuous packing operation, the band of the band reel 80 attached to the reel unit 40 is pulled out by a pool roller (not shown) in the main body of the automatic packing machine 60 through the band insertion port 61, and gradually decreases in size. That is, the rotation of the reel bracket pulley 42 is controlled by the brake belt 48 wound around the V groove of the reel bracket pulley 42. To briefly explain the operation of this control mechanism, the rotation of the reel bracket pulley 42 is controlled by the brake belt 48 wound around the V groove of the reel bracket pulley 42.

The brake tension holder 5
A brake belt 48 attached to the other end of the reel bracket pulley 42 bites into the V groove of the reel bracket pulley 42, and constantly stops the rotation of the reel bracket pulley 42. However, it passes through the free slide roller 51 movably attached to the tip of the reel brake arm 49, the band guide roller 24 attached to the roller bracket 23, and the band guide roller 24 attached to the double roller bracket 28. When the band being fed to the band insertion port 61 of the automatic packing machine 60 is drawn in by a pool roller (not shown) in the automatic packing machine 60,
The band rotates the reel brake arm 49 clockwise in FIG. 3 using the shaft 55 as a fulcrum via the free slide roller 51, and the brake belt 48 releases the reel bracket pulley 42. Then, since the band is stretched by the pool roller, the band reel 80
rotates together with the band coil 70 in a counterclockwise direction on the paper of FIG. 3, and the band is drawn into the automatic packaging machine 60. When the band is pulled excessively by the rotational inertia of the band reel 80, the band releases the free slide roller 51, and the reel brake arm 49 is rotated counterclockwise by the bias of the spring 50. , the brake belt 48 is wrapped around the V groove of the reel bracket pulley 42 and rotation is stopped. By repeating the above steps, the band of the band coil 70 attached to the reel unit 40 gradually decreases. As the number of bands decreases, the band remaining amount detection bar 31 slides downward in FIG. Upon receiving a signal from the alarm device 34, the person in charge of the work will immediately turn on the band remaining amount detection bar 3 as soon as the band runs out.

At this time, the stopper pin 15 is placed on the rotating disk 12 without being removed from the stopper pin hole 19, which is the locking part of the stopper, so that the lower end surface of the stopper pin 15 slides on the mount 11 surface. When the rotary disk 12 is rotated 180 degrees, the stopper pin 15 on the reel unit 40 side, on which the band coil 70 is already attached, is inserted into the stopper hole 18 by its own weight, and the rotary disk 12 is fixed to the pedestal 11. Next, the band end of the band coil 70 is pulled out and passed through the free slide roller 51, passed through the band guide roller 24 of the roller bracket 23, and then passed between the band guide rollers 24, 24 of the double roller bracket 28. During this time, there is enough room for 2 to 4 packages of the bands accumulated in a pool box (not shown) in the main body of the automatic packing machine 60, so the packing operation will not stop.
It continues. As soon as the band in the pool box runs out, the packing line is stopped and the band guide roller 2 of the double roller bracket 28 is removed.
The tip of the band passed between 4 and 24 is inserted into the band insertion port 61 of the automatic packaging machine 60, the band is set in the automatic packaging machine 60, and the operation of the packaging machine is started. Therefore, since the band reel 80 can be replaced quickly and easily, the time required to stop the packaging line can be kept to a minimum. Next, rotate the band remaining amount detection bar 31 to
Band coil 70 of replaced reel unit 40
Place it on the upper end surface. Then, a new band coil 70 is attached to the other reel unit 40 where the aforementioned band is missing. In this way,
The person in charge of the work can prepare for the next signal from the alarm device 34. Another embodiment will be described with reference to FIG. 6, omitting the same parts as the above embodiment. The rotary disk 12 has a circular shape, and a guide plate 71 is provided around the entire circumference of the rotary disk 12. and fix the stopper mounting plate 73 to the pedestal 11 so as to be located outside the guide plate 71.
The stopper pin 74 is inserted into the hole drilled in the stopper mounting plate 73, and the stopper pin 74 is urged via the spring 75 so that the tip of the stopper pin 74 is always in contact with the guide plate 71, and the stopper pin 74 is inserted and inserted. Two locking holes 72 are provided in the guide plate 71, and the two locking holes 72 are provided at symmetrical positions with respect to the rotation axis of the rotary disk 12. Therefore, by rotating the rotary disk 12, the rotary disk 1
When replacing the reel unit 40 on the top of 2,
First, the stopper pin 74 is pulled and the tip is removed from the locking hole 72, and the rotary disk 12 is rotated. When you release your hand from the stopper pin 74, the stopper pin 74 is urged toward the guide plate 71 by the spring 75, so the tip of the stopper pin 74 comes into contact with the outer peripheral surface of the guide plate 71.
When the turntable 12 is rotated 180 degrees, the other locking hole 7
The stopper pin 74 is inserted into the rotary disk 12.
is fixed to the frame 11 and replaced with the other reel unit 40 on the upper surface of the rotary disk 12.

【effect】

Since the present invention is configured as described above, it produces the effects described below. Since the position of the reel unit can be lowered, the band coil can be easily attached, and the work is not too hard for female workers. In addition, since the two reel units are positioned symmetrically around the rotation axis of the rotary disk, it can be used as a double band reel mounting device arranged in parallel positions.
Requires minimal footprint. Furthermore, since the reel unit can be positioned low and there is no need to provide a high frame, it can be manufactured with a simple structure and at low cost. In addition, since the band reel is always used in one place, the installation of band guide rollers to guide the band pulled out from the band reel to the band insertion slot of the packaging machine body is minimal, and the band is simple and constant, making it easy and quick to work with. Furthermore, since only one band remaining amount detection device is required and the detection signal generating means only needs to be set at one location, the remaining band amount can be constantly and consistently detected at low cost.
