Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lid member (a synthetic resin lid or a synthetic resin lid and its lid, which is attached to the bottle mouth of a reusable beverage bottle such as a milk bottle. Method and apparatus for removing the shrink wrap mounted on it.

[0002]

2. Description of the Related Art Conventionally, a bottle bottle for a reusable beverage such as a milk bottle is fitted with a paper lid, and when the bottle is washed for reuse, Since the paper lid was already removed, it was not necessary to provide a special machine for removing the lid. There was also a bottle that was not drunk and returned to the cleaning process for reuse without removing the lid, so in this case a lid removal work was required, but since the lid was made of paper,
A combination of manual removal and water jet spraying on the bottle supply conveyor connected to the bottle cleaning device was sufficient.

[0003]

In recent years, instead of a paper lid, a bottle of milk bottle is capped with a synthetic resin lid, which is then shrink-wrapped and supplied to the market for shrink-wrapping. Also, the lid made of synthetic resin is removed for drinking, and then the lid made of synthetic resin is refitted in the bottle and returned. In particular, in a place where a large amount of milk bottles are used, such as school lunches, it is now common to cover empty bottles after drinking with synthetic resin lids and return bottles.

Removal of a large amount of milk bottles covered with such synthetic resin lids by manual work as in the conventional case,
It was difficult to remove the lid with a combination of removal by spraying with water jet. That is, when removing by water jetting, even if the conventional paper lid is removed, the nozzle may be clogged, the paper may not be cut, and the removal rate may not be 100%. This is because this problem becomes more serious in the case of a lid made of synthetic resin and capped on the bottle opening.

As a bottle to be reused, there is a beer bottle, and in the case of a beer bottle, the lid (crown) is capped and returned, so that the bottle is reused before the cleaning process for reuse. The lid (crown) needs to be removed. In such a beer bottle, the lid (crown) is removed from the bottle mouth by using a jig for hooking and pulling the lid (crown). However, the size of the hook of the lid (crown) is 0.5 ~
Since it is around 1.0 m / m, there is a problem that empty vibration occurs during withdrawal, and in order to prevent empty vibration, the bottom part of the beer bottle is fixed inside the case that accommodates multiple beer bottles. There was a need. In addition, since a fixed space for inserting the jig of the hooking portion is required, the device has to be upsized, and the removed lid (crown) is scattered on an unspecified place. . That is, it is common in that the lid that is capped on the upper end opening of the bottle is removed, but the conventional removal of the lid (crown) of the beer bottle has various problems as described above. Existed.

[0006] Therefore, as described above, a method and an apparatus for removing the lid from a large amount of milk bottles to which a lid made of a synthetic resin, which has been recently adopted, is attached, is particularly desired. While not paying attention to the fact that the lid (crown) of beer bottles is different from the conventional lid (crown) removal, the lid is made of synthetic resin. There is a need for methods and devices that can meet this new challenge.

[0007]

The milk bottle provided for drinking contains milk, is covered with a synthetic resin lid, and is shrink-wrapped on the lid. The consumer removes the shrink wrap, removes the synthetic resin lid, drinks, and then covers the lid and returns. Therefore, milk bottles that are brought into the washing process for reuse are mostly covered with synthetic resin lids, but some of them are not made for drinking and are made of synthetic resin. It also includes shrink-wrapped products from the top of the lid. Therefore, the bottle lid member removing apparatus according to the present invention has not only the function of removing the synthetic resin lid, but also the function of simultaneously removing both the shrink wrap and the synthetic resin lid. That is, the covered member in this specification includes not only a synthetic resin lid but also a synthetic resin lid and a shrink wrap mounted on the lid.

[0015]

[Embodiment 1] FIG. 1 is a front view in which a part of a covered member removing device of the present invention is omitted, and FIG. 2 is a right side view of the same. For the sake of simplicity, the cover member removing tool 17 shown on the left side of FIG. 2 is omitted in FIG.

Milk bottle 1 (1a, 1b, 1) returned
c), 1d, 1e, 1f, ...) are grouped by the roller conveyors 9a and 9b, for example, into a set of 40 (5 horizontal rows × 8 vertical rows in the traveling direction from right to left in FIG. 1). And is transferred to the covered member removing device. The milk bottle transferred to the rear surface side (in FIG. 1) of the covered member removing device (right side in FIG. 2) is then moved to the left side in FIG. 2 by the fluid pressure cylinder 9e as shown by arrow 9d (FIG. 2). It is moved to the lid member removal position located on the front side of FIG. 1.

Above the cover member removing position, cover member pulling tools 8, 8 are arranged. Cover member pulling tool 8, 8
Is erected on the machine bodies 19 and 19 so as to be slidable in a direction indicated by an arrow 16 in FIG. 2 and a direction opposite thereto, and includes a first fluid pressure cylinder 6 having rods 6a, 6a that move up and down. 6 and the lower ends of the rods 6a and 6a, and the hook portions 2 (2a, 2b, 2c, 2d, 2e, 2f, 2), respectively.
g, 2h), 3 (3a, 3b, 3c, 3d, 3e, 3
f, 3g, 3h) a set of two hook blades 4 and 5
(4a and 5a, 4b and 5b, 4c and 5c, 4d and 5d, 4e and 5e, 4f and 5f, 4g and 5g,
4h and 5h) a plurality of cover member hooks 7 having tips
(7a to 7h).

The plurality of cover member hooks 7 are arranged so that the positions of the hooking blades at their tips correspond to the positions of the upper end mouths of the milk bottles mounted at the cover member removing position. Further, the number of the latches 7 corresponds to the number of milk bottles mounted at the lid member removal position, and in this embodiment, 40 (5 rows in the horizontal direction from right to left in FIG. 1). Two sets (80 pieces in total) are arranged with one set of 8 columns in the vertical direction.

Two hook blades 4 and 5 of the cover member hook 7
Is a state in which the pair of blades 4a and 5a are closed (states in which they overlap each other) (FIG. 3 (a)) and are widened in the lateral direction (FIG. 3 (c)). It is configured so that it can be moved to vice versa. In this way, in order to widen (widen) and narrow the width of the two hooking blades 4 and 5 of the hooking tool 7, the second fluid pressure cylinder is used to control the movement of each of the hooking blades 4 and 5. One set of 10a and 10b is arranged with respect to the entire 40 of the lid member pulling out tools 7. In this embodiment, a set of fluid pressure cylinders 10a and 10b controls the movement of the hooking blades 4a to 4h and the hooking blades 5a to 5h of the 40 pulling tools 7, respectively. It is also possible to control by using the fluid pressure cylinder.

In the above description, the supporting length for supporting the hooking blades 4 and 5 on the cover member hooking device 7 allows the cover member to be removed with a time difference, and therefore has the following predetermined relationship. Is configured to have. That is, as shown in FIG. 5, the left side of the cover member removing device of FIG. 10 hook blades 4a, 5 in a row (horizontal row) 7b
The support lengths of a, 4b, and 5b are the same, and similarly,
Ten latching blades 4 in a row (horizontal row) of latches 7c and 7d
The supporting lengths of c, 5c, 4d, and 5d are the same, respectively.
e and 7f rows (horizontal rows) of 10 hooking blades 4e, 5e,
The support lengths of 4f and 5f are the same, respectively, and the latches 7g and 7h.
Row (horizontal) 10 hook blades 4g, 5g, 4h, 5h
The support length of each is the same. On the other hand, the supporting length of the adjacent two rows of the retaining blades 4c, 5c, 4d, 5d is longer than the supporting length of the retaining blades 4a, 5a, 4b, 5b of the two rows of ten. Is the next two rows of 10 hook blades 4
e, 5e, 4f, 5f have a longer support length, and
The supporting length of the rightmost two rows of 10 hooking blades 4g, 5g, 4h, 5h is the longest.

In this embodiment, as shown in FIG. 5 (c), the hooking portions 2a, 3a, 2b, 3b of the two rows of hooking blades 4a, 5a, 4b, 5b are at the highest position, Then, the positions of the hooking portions 2 and 3 of the blades become lower in order for the hooking portions 2c, 3c, 2d, 3d in the hooking blades 4c, 5c, 4d, and 5d of the adjacent two-row set, and for each two-row set. So that the hook blade 4
By constructing a and 5a to 4h and 5h,
The supporting length for supporting the hooking blades 4 and 5 on the cover member hooking tool 7 is increased for each two-row set.

However, since it suffices to be able to remove the covered member with a time lag, the hooking blade is supported so that the covered member can be removed with a time lag when the covered member hook 7 rises. The configuration is not limited to the configuration of the present embodiment described above, as long as the configuration can adjust (change) the supporting length or the blade length to be used.

Further, in the apparatus of the present invention, the bottle holder 12 having the plurality of bottle holder projections 11, 11 is above the cover member removing position and below the plurality of cover member hooks 7. Is fixed to the airframes 19 and 19. The bottle holder 12 has a space into which the plurality of lid member hooks 7 can be inserted, at a position corresponding to the position of the upper end opening of the milk bottle aligned with the lid member removal position. A plurality of bottle pressing projections 11 for pressing the shoulder portion of the bottle that has been pulled up to a position corresponding to the upper side between the bottles of the plurality of milk bottles aligned in the lid member removal position,
Have 11.

The removal of the covered member by the covered member removing apparatus of the present invention will be described below. A plurality of milk bottles (in the case of the present invention, 40 units of horizontal 5 rows × vertical 8 columns in the traveling direction from the right side to the left side in FIG. 1) are treated as one unit, and two units (total of 80) are processed An example will be described.

When the milk bottle is aligned with the lid member removing position shown in FIG. 1, the rod 6 is moved by the fluid pressure cylinders 6, 6.
When a and 6a are pushed downward, the covered member hooks 7 (7a to 7h) and 7 (7a to 7h) move downward. The fact that the milk bottle is aligned with the lid member removal position is
It can be detected by using a limit switch (not shown) or the like.

During the downward movement of the cover member hooking members 7, 7, the two hooking blades 4, 5 of the cover member hooking member 7 are moved as shown in FIGS. ) (2 sets of hook blades 4 and 5 overlap each other).

When the hooking blades 4 and 5 collide with the upper surface of the lid member 13, the hooking blades 4 and 5 pierce the lid member 13 and project into the upper end openings of the milk bottles 1a to 1h. b).

When the lowering of the cover member hook 7 is completed, the operation of the fluid pressure cylinders 10a and 10b causes the hook blades 4a and 5a to 4h of the cover member hooks 7a to 7h.
And 5h are widened (FIG. 3 (c). The end of the lowering of the hook 7 can be detected by, for example, a limit switch (not shown). it can.

Next, by operating the fluid pressure cylinder 6 in the opposite direction, the rod 6a is pulled upward, and the lid member retaining members 7a to 7h are also pulled upward. Hanging blade 4
Since a and 5a to 4h and 5h are widened (being laterally widened), when the hooking portions 2a and 3a to 2h and 3h of the hooking blades come into contact with the lower surface of the covered member 13, The milk bottles 1a to 1h are lifted up together with the capped cover member 13 (FIGS. 4 (a) and 6 (a)). Bottle holding tool 12 in which bottle holding projections 11, 11 are arranged above the milk bottle and between the milk bottles, respectively.
Is fixed to the machine body 19 above the cover member removing position, the shoulder of the milk bottle lifted is
1 and 11, the lid member 13 is supported downward, whereby the covered member 13 is removed (pulled out) from the upper end opening of the bottle (FIG. 4B). The milk bottle from which the covered member 13 has been removed (removed) is released from the locking by the locking devices 7a to 7h, falls downward, and returns to the covered member removal position (FIG. 4 (b), FIG. 6 (b)).

At this time, as described above, the length for supporting the hooking blades 4a and 5a to 4h and 5h of the cover member hooking tools 7a to 7h is a two-row set (10 pieces) directed in the traveling direction. Since the cover member hooks are gradually longer, the cover member 13 is first removed in the ten covered member hooks 7a and 7b, and then the cover member hooks are removed. Tools 7c, 7
The covered member 13 is removed from the ten lines in the row d. In this way, the lid member 13 is removed every two rows (10 pieces) with a time difference (FIG. 6A).
(B)) It becomes possible to remove the covered member 13 with a small force as compared with the case where the covered member 13 is removed (withdrawn) from 40 milk bottles at once (simultaneously), which saves labor and energy. It is also possible to reduce the weight of the entire device.

When the lid member 13 is removed (pulled out), the shoulder of the milk bottle that has been lifted upward by the lid member locking members 7a to 7h is pushed by the bottle pressing protrusion of the bottle pressing member 12. Since it is sufficient to support downwards with 11, it is not necessary to provide a special jig for fixing the bottle to prevent the milk bottle from moving upwards, and no extra jig for such a jig. No need to reserve space. Instead of the bottle pressing tool 12 having the bottle pressing projection 11, a configuration may be adopted in which the bottom sides of the bottles 1a to 1h are pressed with a force larger than the pulling-out force. Since it is sufficient to hold down with a force larger than the upward pulling force by 7a to 7h, it is necessary to provide a special jig for fixing the bottle to prevent the milk bottle from moving upward as described above. There is no.

In this embodiment, the covered member 13 in the row of the covered member hooks 7a and 7b, which is the first two-row set.
It takes 0.1 to 0.5 seconds between the removal of (10 pieces) and the removal of the covered members 13 (10 pieces) in the row of the covered member hooks 7c and 7d which are the next two-row set. The length for supporting the hooking blades 4a and 5a to 4h and 5h of the cover member hooking tools 7a to 7h was slightly increased for each two-row set so that the gap is opened. The difference in blade support length or the difference in blade length can be variously changed according to demand.

According to the present embodiment, the operation of the fluid pressure cylinder 6 lowers the cover member hook, and the hooks 7a to 7a.
After inserting the hooking blades 4 and 5 of 7h into the covered member 13,
It was possible to widen the hooking blades 4 and 5, raise the hooking tools 7a to 7h, and remove the covered member 13 in 3 seconds.

As shown in FIG. 1, 40 lines (5 rows × 8 columns)
After removing the covered member 13 from a total of 80 milk bottles, the milk bottle from which the covered member 13 is removed is moved to the left roller conveyor 9c by the rotary roller 14. It is moved to the washing process.

On the other hand, the lid member pulling tool 8 is moved to the lid member removing position by the fluid pressure cylinder 15 as shown by an arrow 16 (FIG. 2). A covered member removing tool 17 is arranged at the covered member removing position, and the covered member removing tool 17 can be inserted with the covered member retaining tools 7a to 7g, but the covered member 13 can be inserted. It has impossible voids 18, 18.

At the time when the cover member pulling out tool 8 is moved to the cover member removing position, the hooking blades 4 of the hooking tools 7a to 7h,
No. 5 is still widened (FIG. 7 (a)). Here, the fluid pressure cylinders 10a and 10b are operated in the opposite direction to the state in which the latching blades 4 and 5 are closed (the pair of latching blades 4 and 5 overlap each other). Return (Fig. 7
(B)). Then, when the rod 6a is raised by the cylinder 6 and the latches 7a to 7h are raised, the covered member 13 that has been removed from the milk bottle previously cannot insert the voids 18, 18, and therefore the cover member 13 shown in FIG. ), As shown in FIG.
It can be easily removed from the hooking blades 4 and 5 of the hooking tools 7a to 7h.

In this case, since the hooking blades 4 and 5 are already closed (overlapping each other), two sets of 5 rows in the horizontal direction and 8 rows in the vertical direction, a total of 80 covered members 13 are provided. Will be pulled out at the same time, but with the hooking blades 4 and 5 closed, it is only necessary to pull out the covered member 13 already provided with holes through which the hooking blades 4 and 5 can be inserted, so a large force is required. It can be taken out without requiring.

Further, the cover member removing device 17 is fixed to the machine body 19 while keeping a predetermined angle (tilting) toward the traveling direction of the milk bottle (from right to left side in FIG. 1). As a result, it is also possible to remove the lid members 13 in groups of two rows or in a required number, as in the case of removing the lid member 13 from the milk bottle.

Since the covered member 13 removed from the milk bottle as described above is always discarded at a fixed position (position where the covered member is removed), the removed covered members are scattered. Problem does not occur.

After removing the cover member 13, the fluid pressure cylinder 15 (FIG. 2) is operated in the opposite direction to return the cover member pulling tool 8 to a position above the cover member removing position.

With the above, one step of removing the covered member 13 is completed. According to the apparatus of this example, 60 per hour
0 cases, 24,000 milk bottles in total
It is possible to remove 3.

Next, referring to FIGS. 8 and 9, the hooking blades 4 and 5 will be described.
The removal and replacement of will be described. The latching blades 4a and 5a are attached to the respective latches 7a to 7h, and as shown in FIG.
Five hooking blades 4a and five hooking blades 5a are attached. In the device of the present invention, these five hooking blades 4a, 4a, 4a, 4a, 4a and 5a, 5a, 5a, 5
a and 5a are fixed to one plate, and each plate is connected to the fluid pressure cylinder 10 respectively.
It is controlled and operated by a and 10b, and moves in the left-right direction to open and close the pair of hooking blades 4a and 5a (move to the original state where they overlap with the widening). .

In FIG. 8, the bolts 20 and 20 are loosened,
In FIG. 8, on both sides (in FIG. 1, the front and back sides)
The plates 21 and 21 are removed, and the five latching blades 4a, 4a, 4a, 4a, 4a and 5a, 5a in the row of the latching tool 7a,
The plates fixing 5a, 5a and 5a are removed. The hooking blades 4a and 5a are bolts 2 as shown in FIG.
Since it is fixed to the plate with 2 and 22, bolt 2
The latch blades 4b, 5b can be removed by loosening 2, 22.

In this way, the five consecutive blades 4a or 5a for each horizontal row can be easily removed and replaced, so that two sets of horizontal rows and vertical rows are provided in the traveling direction, for a total of 80 rows. It is possible to replace the hooking blade of the covered member hooking tool within 2 minutes (60 seconds), and the device is stopped by the hooking blade replacement, so that the next process is not affected.

[0045]

[Embodiment 2] The adjustment of the length of supporting the hooking blades for enabling the removal of the covered member with a time lag will be described with reference to FIGS.

In the first embodiment, the hooking portions 2, 3 of the hooking blade are used.
The length for supporting the hooking blades was adjusted by adjusting the height of each of the two rows to gradually decrease, but in the present embodiment, the height of the hooking portions 2 and 3 of each hooking blade is adjusted. Are controlled by the fluid pressure cylinders 10a and 10b,
When fixing the hook blade to the operated plate with bolts,
Hooking blade support plate 23 between the blade portion and the fixing portion to the plate
By increasing the lengths of a and 24a (FIG. 12) for each two-row set, the length for supporting the hook blade is adjusted.

FIGS. 10 and 11 show the first embodiment shown in FIGS.
Similarly to the above, it is a view seen from the front side of FIG. 1, but in order to easily explain that the lengths of the retaining blade support plates 23a, 24a are gradually increased, the retaining blades 4a, 5a ,. ...., 4
The widening of h and 5h is shown so that it can be seen in the front.

When the cover member hooks 7a to 7h are lowered (FIGS. 10 (a) and 10 (b)) and the blades are widened when the lowering is completed, the leftmost two rows of hook blades 4a to 4a are set. The latching blade support plates 23 of the two adjacent sets of latching blades 4c to 5d are longer than the lengths of the latching blade support plates 23a to 24b in 5b.
c to 24d is longer, and the rightmost two rows of hook blades 4
Since the lengths of the retaining blade support plates 23g to 24h in g to 5h are the longest, as shown in FIG. 10 (c), the tips of the retaining blades gradually go deeper into the milk bottle every two rows. It will rush.

As a result, when the cover member hooks 7a to 7h are raised, as shown in FIGS. 11 (a) and 11 (b), a two-row set (10 pieces) is sequentially arranged from the left side with a time difference. The covered member 13 is removed.

In this example. Other configurations, operations, and effects are the same as those in the first embodiment, and the description thereof is omitted.

Although the preferred embodiments of the present invention have been described above, the present invention is not limited to these embodiments and can be variously modified within the scope of creation of the technical idea disclosed in this specification. Is.

As the fluid pressure cylinders 6, 9e, 10a, 10b, 15 in the embodiment of the present invention, for example, pneumatic cylinders can be adopted. Further, the fluid pressure cylinder in this embodiment is sufficient if it can move the object linearly. Therefore, instead of the fluid pressure cylinder, a rodless cylinder, a rack and pinion, a crank device, a cam device, etc. are known. Mobile devices can be used. For the movement by the fluid pressure cylinder in the present embodiment, the end of the operation is detected by using a known limit switch, sensor, stopper or the like, and the inflow amount of the pressurized fluid is regulated to regulate the movement amount of the fluid pressure cylinder. can do.

[0053]

According to the present invention, unlike the case of removing (pulling out) the covered members at a time (simultaneously) from a large amount of milk bottles, the covered members are sequentially removed with a time difference from a predetermined number of milk bottles. Since it can be removed (removed), labor and energy can be saved, and the weight of the entire device can be reduced. The removal of the covered member with a time lag is achieved by gradually changing the length for supporting the hooking blade of the covered member hooking tool or the length of the blade for each predetermined number of covered member hooking tools. Therefore, the interval can be freely adjusted, and removal (withdrawal) from a large amount of milk bottles can be performed in a short time.

Further, in removing (withdrawing) the covered member, the hooking blade of the covered member hooking device pierces the covered member having a certain area (the area of the mouth of the milk bottle). Therefore, at this time, it is not necessary to arrange a special jig around the milk bottle to prevent the milk bottle from rolling.

Further, when the lid member is removed (pulled out), the shoulder of the milk bottle that has been lifted upward by the lid member hooking device is supported downward by the bottle holding projection of the bottle holding device. Is sufficient, there is no need to provide a special jig to secure the bottle to prevent the milk bottle from moving upwards, nor does it require extra space for such a jig. .
