[0004]
[Problems to be solved by the invention]
However, in the above-described direct charging method, since the operator inputs it through the opening 51A for injection, it is difficult to adjust the input amount. If the input amount is too large, it is difficult to perform the press work. If the amount is too small, the number of presses must be increased, which causes a problem that the efficiency of the press work is poor.
Further, the belt conveyor system has a problem that a large space is required to install the belt conveyor 62.
Further, when the hollow container is introduced into the press apparatus from the second floor, there is a problem similar to the direct introduction method.
[0005]

According to the storage amount detected by the detection sensor , having a main body through which the inside penetrates in the vertical direction and having the hollow container inserted therein, and a plurality of blade members that are rotatably provided in the main body. comprising a rotary drum to be introduced into the hopper by adjusting the dropping amount of the inserted said hollow container into said body, and a drive source for rotationally driving the rotary drum Te, before Rotating drum, is characterized in that it is provided offset to one side from the horizontal width center axis of the rotation axis is substantially orthogonal to the vertical direction of the body.
[0007]
In the above, a PET bottle etc. are mentioned as a hollow container. Further, any number of blade members of the rotating drum may be provided as long as the amount of fall of the hollow container put into the main body can be adjusted. Further, the blade member may be formed by a single member, or may be formed by two pieces that allow other members to be attached to and detached from the single member. Further, the blade member may be continuous in the longitudinal direction of the rotary drum, or a plurality of blade members may be arranged in parallel in the same row. In this case, it is necessary to prevent the hollow container from falling off between adjacent blade members. Furthermore, it is preferable to use a motor as the drive source, but any device that can rotate the rotating drum may be used.
[0008]
In the present invention, the hollow container charged in the main body is dropped into the hopper by the amount supported by the predetermined blade member by rotating the blade member simultaneously with the rotation of the rotating drum. In this way, since the drop amount can be adjusted while being charged, an appropriate amount of a hollow container can always be secured in the hopper, and an appropriate amount of the hollow container can be charged from there into the hollow container press device, so that a continuous pressing operation can be performed. The work efficiency of press working is improved.
Moreover, since the hollow container charging device is disposed above the hopper of the hollow container pressing device, it can be provided even if there is little space.

The tip member may be formed of an elastic body.
[0010]
In the above, rubber is preferably used as the elastic body. However, a synthetic resin such as plastic may be used as long as the same function as that of the rubber can be obtained. Moreover, in order to attach the tip member to the attachment member, a round screw or the like may be used, or adhesion may be performed.
[0011]
In the present invention, since the tip member of the blade member is formed of an elastic body, the tip member can escape even when a hollow container is sandwiched between the blade member and the main body during rotation of the rotary drum. As a result, damage to the blade member is prevented, overload to the drive source is prevented, and the life of the drive source is extended.
[0012]
In the present invention, as described above, the axis of the rotary shaft of the rotary drum is provided so as to be shifted to one side from the center of the width dimension in the horizontal direction substantially perpendicular to the vertical direction of the main body.
[0013]
In the present invention, since the rotation shaft is shifted to one side of the width of the main body, the gap between the other side and the main body becomes large, and the hollow container drops only from the other side, and the amount of drop is adjusted. Is easy, and it is not necessary to increase the width dimension more than necessary, so that the entire apparatus can be made compact.

[0031]
The blade members 9 of the present embodiment are determined based on such conditions, and eight blade members 9 are provided on the circumference of the drum body 8 at equal intervals as described above.
[0032]
As shown in FIG. 8, the drum body 8 provided with the blade member 9 is stopped when the PET bottle 100 put into the main body 5 is prevented from dropping by the blade member 9. 8 is once stocked in the upper part.
Further, as shown in FIG. 9, the drum body 8 is rotated when the PET bottle 100 once stocked on the top of the drum body 8 is moved by the movement of the blade member 9 that rotates as the drum body 8 rotates. For example, 5 to 6 pieces supported by the blade member 9 are dropped. That is, the amount of fall of the PET bottle 100 can be adjusted by the blade member 9.
[0033]
Next, the effect | action of this embodiment is demonstrated based on FIG.
At the start of the first press, the work is started by turning on the power of the hollow container press device 20, the charging device 1, and the like.
First, the worker M sorts out the PET bottle 100 from the garbage 102, the PET bottle 100, etc. conveyed by the conveying means 36, and this PET bottle 100 is put into the main body 5 of the charging device 1 from the opening 35A of the floor 35. In
[0034]
The PET bottle 100 introduced into the main body 5 is continuously dropped into the hopper 21 in the state shown in FIG. 9 by the rotating drum body 8. When the detection sensor 26 provided in the hopper 21 detects that a predetermined amount of the PET bottle 100 has been charged into the hopper 21 (sensor ON), the rotation of the drum body 8 of the charging device 1 is stopped (OFF). However, the charging of the bottle 100 into the main body 5 of the charging device 1 is continued until the state shown in FIG.
[0035]
When a predetermined amount of the PET bottle 100 is put into the hopper 21, the opening / closing cylinder 32 of the hollow container press device 20 is driven to open the opening / closing lid 33, and the PET bottle 100 in the hopper 21 is inserted into the hollow container press.

[0036]
Until the detection sensor 27 provided in the main body 23 detects the amount of the PET bottle 100 put into the press chamber of the main body 23 of the hollow container press apparatus 20, the drum body 8 passes through the hopper 21 by the same operation as described above. Then, the insufficient PET bottle 100 is replenished.
[0037]
When the detection sensor 27 detects that a predetermined amount of the PET bottle 100 has been introduced into the press chamber of the main body 23 of the hollow container press device 20, the inlet opening / closing cylinder 32 is driven to close the opening / closing lid 33; The pressing cylinder 25 is driven to lower the compression mechanism 24 to perform the first pressing operation.
At this time, the PET bottle 100 is put into the hopper 21 until the detection sensor 26 provided in the hopper 21 detects it by the same action as described above.
[0038]
When the first pressing operation is completed, the pressing cylinder 25 is driven to raise the compression mechanism 24, and preparation for the second pressing operation is performed.
Then, the bale 101 formed by performing a predetermined number of pressing operations is discharged from the discharge unit 28 of the hollow container press device 20, and the bale 101 is bundled by the bundling machine 29 and sent to the bale receiving table 30.

According to this embodiment as described above, there are the following effects.
(1) The PET bottle 100 put into the main body 5 of the charging device 1 is once stocked in the main body 5 by a plurality of blade members 9, and the blade member 9 rotates at the same time as the drum body 8 rotates. The PET bottle 100 held by the blade member 9 is dropped into the hopper 21. For this reason, since an appropriate amount of PET bottle 100 can always be secured in the hopper 21 and an appropriate amount of bottle 100 can be put into the hollow container press device 20 from there, a continuous pressing operation can be performed, and the working efficiency of the press working is improved. To do.
[0040]

(3) The tip member 11 of the blade member 9 is an elastic body, and the tip member 11 escapes even if the PET bottle 100 is sandwiched between the blade member 9 and the main body 5 when the drum body 8 rotates. Damage to the blade member 9 is prevented, overload to the motor 15 is prevented, and the life of the motor 15 is extended.
[0041]
(4) Since the rotating shaft 6 is shifted from the center of the width dimension of the main body 5 to one side, the gap between the other side and the main body 5 becomes large, and the PET bottle 100 falls only from the other side. It is easy to adjust the amount, and it is not necessary to increase the width dimension more than necessary, so that the dosing device 1 can be made compact.
[0042]
(5) Since the rotary drum 7 is provided inside the main body 5 and the PET bottle 100 is put into the main body 5, there is an effect that the main body 5 serves as a buffer for the bottle 100.
[0043]
The present invention is not limited to the above-described embodiments, and includes the following modifications as long as the object of the present invention can be achieved.
For example, in the above-described embodiment, the rotating drum 7 provided in the main body 5 of the charging device 1 is arranged so that the longitudinal direction of the drum body 8 is parallel to the long side 2A of the gantry 2. Instead, the drum body 8 may be arranged so that the longitudinal direction thereof is parallel to the short side 2B of the gantry 2.
[0044]
In the above-described embodiment, the blade member 9 of the drum body 8 is determined by determining the relationship and the number of the PET bottle 100 with respect to the main body 5 on the basis of the PET bottle 100 containing 1.5 liters having a diameter of L3. However, the present invention is not limited thereto, and for example, a press such as a 1 liter PET bottle may be performed. In this case, the number of sheets and the like may be determined based on the necessary conditions of the blade member, as described above, with the diameter of the bottle as a reference.

And a gap may be provided on both sides of the rotating drum 7. Even if it does in this way, since PET bottle 100 thrown into the clearance gap side opposite to a rotation direction is lifted by the blade member, it does not fall from the clearance gap. However, since a gap is provided on both sides of the rotating drum 7, there is a problem that the apparatus becomes large.
[0047]
In the above embodiment, the charging device 1 is disposed immediately below the charging opening 35A formed in the floor 35 on the upper floor, and the PET bottle 100 is charged into the main body 5 of the charging device 1 from the opening 35A. However, for example, a cover 40 is provided between the opening 35A and the main body 5 as shown by an imaginary line in FIG. 1, and the bottle 100 introduced from the opening 35A jumps out of the main body 5 to the outside.
