It is adapted to be moved up and down by meshing with 3b. At both sides of the conveyer C and at the entrance of the stretch derailleur, a standby stopper 4 is conveyed on the main body base 3 so as to be rotatable around an arm shaft 8 supported by a bearing 17 shown in FIG. It is arranged so that the coming barrel O can be stopped once.

As can be seen from FIG. 3, an air cylinder 18 is swingably attached to a cylinder bracket 6 fixedly mounted on the main body base 3, and a piston rod of the air cylinder 18 has a ring ball of a standby stopper 4. Twenty are pivotally attached. This ring ball 20 is attached to one of the three-armed arms of the standby stopper 4, and the other arm guides the barrel B and temporarily stops it.
b is pivotally attached. Here, the large barrel B conveyed by the conveyer C is stopped by the roller 4a of the waiting stopper 4 which is once closed, and the sensor S (constant) as shown in FIG. Whether the label L is attached to the abdomen of the large barrel B and the inverted barrel (the spear valve D is not facing upward) by means of, for example, touch sensors provided in three stages along the conveyor C at intervals of The presence or absence of is detected. If the label L is not attached and it is not an upside down barrel, the barrel B is placed at the next label peeling position.
After confirming that there is no residue, the open barrel 4 detected is opened and the air cylinder 18 is opened and controlled by the pneumatic circuit (not shown), and the movement of the conveyor C and the pushing out of the roller 4b of the standby stopper 4 are performed. By the action, it is sent to the next label stripping (delabeling) place.

Next, at the label peeling position, the label suction tube 1
0, a heat cutter 11, and a pair of centering stoppers 5 are provided. First, as shown in FIG. 3, a pair of centering stoppers 5 are provided on the main body base 3, a cylinder bracket 7, and an air swingably mounted on the cylinder bracket 7 in order to center the barrel B at a predetermined label peeling place. A cylinder 19 and a ring ball 21 attached to a piston rod of the air cylinder 19 are rotatably attached. Here, the centering stopper 5 is opened and closed by the air cylinder 19, and once the barrel 5a sent from the standby position guided by the conveyer C and the guide bars 9 on both sides thereof is temporarily received by the roller 5a and peeled off. Center in position. Further, the guide bar 9 is connected to the air cylinder 22 fixed to the mold changing base 2, and is guided by the linear guide 25 to change the mold diameter from the 15-25 liter barrel to the 7 liter barrel. The width of the guide bar 9 is adjusted to adjust the difference (about 25 mm).

Adjacent to this label peeling position, as shown in FIG.
As shown in FIG. 5, the suction tube 10 for sucking the label L attached to the abdomen of the large barrel B, which is detected by the sensor S at a predetermined height and is set by raising and lowering the main body base 3.
A heat cutter 11 that removes the sucked label L while heating is provided. The suction pipe 10 is erected on a bracket 12 attached to the main body base 3, and is attached to the barrel B.
The mouth of the label L is close to the abdomen, and the end of the label L is sucked by a separately provided air suction source (for example, a blower). In particular, the suction tube 10 moves in and out of the abdomen of the large barrel B by the action of the air cylinder 34 along the slide pack 26 erected on the bracket 12. Further, the heat cutter 11 moves in and out together with the suction tube 10, and is constantly urged by a spring (not shown) built in its receiving portion.

In particular, at this label peeling position, a barrel rotating head frame 13 is disposed above the center of the centered barrel K as shown in FIGS. 1 and 2.

A drive unit base 14 is attached to the barrel rotating head frame 13, and the shaft 16 is rotatably supported via a shaft bracket 15 and a rotary ball spline 29 provided on the top of the frame 13. It is like this. And this shaft 16
An air chuck 28 is attached to the tip of the, and moves up and down by the operation of the air cylinder 27 to hold the spear valve D of the large barrel B.

Further, as shown in FIG. 4, the shaft bracket 15 is provided with a pistonic speed reducer 31, a timing pulley 32 and a timing belt 33.
Thus, the barrel L is peeled off by rotating the barrel B, for example, one rotation and a half barrel B.

Next, the operation of the Otaru stretch deraveler thus constructed will be described.

As shown in FIG. 3, the large barrel B, which has been sequentially fed on the conveyor C, is temporarily stopped at the standby position by the standby stopper 4, and the size of the barrel, the presence / absence of the label, the deviation and the upside down. The sensor S detects whether or not it is a barrel.
For example, in the case of a 7-liter large barrel, the linearized motor 23 is driven by this detection result to raise and lower the mold changing base 2 to a predetermined position and set the barrel B to the next peeling position as a standby stopper. The air cylinder 18 is actuated to open and send the No. 4 fluid. If the label is not attached or the barrel is upside down, an alarm is given to the operator by an appropriate method to notify the operator, and the operator is allowed to pass through the system as it is and eliminated by an excluding device separately provided outside the system.

The barrel B sent to the peeling position is centered with its abdomen abutting against the pair of rollers 5a of the centering stopper 5, and then the air chuck 28 descends to move the spear valve D of the barrel B. While gripping and bringing the label suction tube 10 and the heat cutter 11 into contact with the label L to heat the label while sucking the label, the air chuck 28 is rotated to rotate the barrel B (for example, 1
Half the rotation), the label L is peeled off while stretching (stretching) with the heat cutter 11. The peeled label L is sucked by the label suction tube 10 with a blower or the like and removed from the system. After the label peeling (delabeling) is completed, the barrel B opens the centering stopper 5 by operating the air cylinder 19 and carries it out to the next work position by the conveyor C.

In this way, the delabeling from the large barrel B is completed.

EFFECTS OF THE INVENTION According to the cask stretch deraveler of the present invention, the presence or absence of a label affixed to different types of cask and the position of affixation are detected in consideration of the deviation, and peeling is extremely easy and reliable. Therefore, the label removal rate is significantly improved (for example, a label removal rate of about 95% is achieved) as compared with the conventional manual work. As a result, the risk associated with the label peeling work is reduced and the productivity is remarkably improved.
