Description

[Detailed Description of the Invention] Technical Field This invention relates to an automatic insertion device for inserting partitions into a workpiece, and more specifically, it relates to an automatic insertion device for inserting partitions into a workpiece, and more specifically, it relates to an automatic inserting device for inserting partitions into a workpiece, and more specifically, it relates to an automatic inserting device for inserting partitions into a workpiece, and more specifically, it relates to an apparatus for automatically inserting partitions into a workpiece. Protection for products filled with food, seasonings, etc. and stored and packaged in multiple units in cardboard boxes or other transport cases to prevent damage due to impact or interference during transportation. The present invention relates to an automatic partition inserting device configured to insert partitions made of cardboard or synthetic resin plates during the packaging process of the article.

Technical background As schematically shown in Fig. 11, when packing workpieces into boxes, each workpiece w is generally stored in a line in a box B with a partition P interposed between adjacent workspieces, which functions as a protective material to prevent damage. has been done. Then, automatically inserting the partition P by mechanical means after the work w is stored in the box (container) B requires advanced technology and is quite complicated in terms of work. Therefore, the feeding process (feeding line) has traditionally been carried out prior to packing the workpieces into boxes.
During the process, technology has generally been established to automatically insert required small partitions between workpieces. This partition insertion technique is installed on the outside of the line, for example, in response to the fact that workpieces w are intermittently conveyed forward while aligning themselves in groups and maintaining appropriate intervals in a feeding line. Inner partitions P are intermittently fed out one by one from the partition supplying section in a direction perpendicular to the line, and are inserted between the front and rear workpiece rows in the feeding direction while the group of workpieces is at rest. Specifically, (a) as illustrated in Fig. 12a, the partition P is pulled out above the rows of workpieces during the forward movement, and then inserted between the rows of workpieces during the descent process. The manner in which

(b) As illustrated in FIG. 12b, it is possible to implement an embodiment in which the partition P is inserted directly between the rows of workpieces during the advancing process.

However, in any of these embodiments, it has been difficult to insert the partition P depending on the shape and properties of the workpiece.

That is, as illustrated in FIGS. 13a and 13b, when inserting the partition P from above into a workpiece w having a flange f or a large-diameter step f' on the outer periphery based on the above-mentioned mode (a), The lower edge of the partition may come into contact with the flange f or step f', and as a result, the partition P may break or the aligned workpieces w may fall over or become misaligned. . Therefore, in order to avoid the above-mentioned undesirable situation, if an attempt is made to insert the partition P from the side based on the above-mentioned embodiment (b), the flange f of the workpiece will get in the way,
If the workpiece itself has a relatively large weight, the partition P cannot push the workpiece w by itself, so the partition P may be pushed down by the flange f of each workpiece, or bent from the middle. Sometimes I end up doing it. As described above, with the above-mentioned partition insertion technology, it is difficult to insert the partition between the rows of workpieces without losing the original protective function. It is strongly requested.

Purpose This invention is newly proposed to meet the above-mentioned demands and solve the above-mentioned problems.
During the feeding of workpieces to be boxed in multiple pieces, prior to inserting a partition, a leading member, which can be called a "dew-wiping", is advanced to the group of works, and the partition is necessary and sufficient to insert the partition between rows of workpieces. This is an automatic partition insertion device that is configured to quickly and automatically insert the required partitions within the same spacing while ensuring the same spacing. To quickly and properly insert a partition into a workpiece having a certain shape and properties, thereby simplifying the work of packing the workpiece into a box and achieving good boxing.

Embodiments Next, the partition insertion device according to the present invention will be described in detail below with reference to the accompanying drawings, using preferred embodiments. In this embodiment, Fig. 13 a, b
When a workpiece w with a flange-shaped protrusion illustrated in is an object to be inserted into the partition, a partition P made of a horizontally long rectangular plate is inserted on the forward side of the feeding process.
(Made of cardboard) will be mainly described with respect to a mode in which the workpieces (made of cardboard) are inserted between rows of workpieces in each workpiece group W, but of course the present invention is not limited to this.

In order to contribute to an understanding of the technical contents of the device of the present invention, first, the workpiece feeding section will be explained. As shown in FIG. (Four illustrated) work guide rods 14, 14 are laid parallel to the feeding direction. The feed conveyor 16, which is intermittently driven by an intermittent drive section (not shown), is connected to a pair of chains 1 installed on both sides of the bed 12.
It is constructed by connecting an appropriate number of feed support rods 20 between 8 and 18 in a direction perpendicular to the feeding direction. The feed support rod 20 is a workpiece attachment that supports the workpiece in a backward state, and is formed to have approximately the same length as the width of the bed 12, and can receive two rows of workpieces in the feeding direction. Arranged at intervals.

In the feeding section 12 configured as described above, the workpieces w are arranged in rows in the width direction of the bed 12, and as shown in FIG. The work is placed in an upright position, and the two rows of workpieces in the front and back are loaded between each feeder rod 20, and the rear (left side in Figure 3) row of workpieces is placed between the feeder rods 20.
It has come to be backed by direct support from the government. As a result, the work w is for 2 rows (total 6 pieces)
are fed pitch by pitch in accordance with the intermittent operation of the feeding conveyor 16, and in this process, the workpieces located in the front and rear rows are placed in a position where their flanges f are in contact with each other (a so-called pressed state). They are fed forward while being lined up. Reference numeral 98 indicates a photoelectric workpiece detector installed at an appropriate location on the feeding line, and a partition should be inserted between the light emitting element 98a and the light receiving element 98b, which are arranged facing each other on both sides of the bed 12, to block the optical path. Work group W
It is designed to confirm and detect the arrival status, etc.

The partition automatic insertion device according to the present invention, which is configured to correspond to the above-mentioned workpiece feeding mode, includes cyclic movement of the movement operation section 22 (i.e., back-and-forth movement orthogonal to the workpiece feeding direction) and movement of the bed 12.
A movable body support (also simply referred to as a movable body) 56, which is moved as a result of the circular movement (combined with an upward vertical movement), enters between the rows of workpieces in advance to create an interval for inserting a partition. It is equipped with a leading member 64 for installation and a holder 72 for the partition, so that the partition can be inserted horizontally from the outside of the side of the feeding section 10 while each group of workpieces is stopped. ing.

First, the moving operation section 22 side will be explained. As shown in FIG. A movable body 30 is equipped. This movable body 30 is inserted and supported by a guide rod 28 installed horizontally between supports 26 on both sides of the frame 24, and perpendicular to the workpiece feeding direction. The guide trochanter for frame 2
By being fitted between the upper and lower guide rails 36, 36 arranged in parallel inside the cross beam 34 of No. 4, the movable body 30 can move stably and quickly. As an operating means for the movable body 30, a first cylinder 38 is installed horizontally on the upper right side of the frame 24. This cylinder 38 is operated in synchronization with the intermittent movement of the feeding conveyor 16, and has an effective stroke that can be sufficiently adapted to the length of the workpiece row described above.
A connecting tool 42 connected to the tip of the movable body 30 is fixed to the upper surface of the movable body 30 via means such as a bolt or an elongated hole so that its position can be adjusted. As a result, before moving, the movable body 30 waits with the right end of the guide rod 28 as the starting end (backward end) as shown in FIGS. ), it is possible to reciprocate over the forward end on the left end side of the guide support rod 28.

A second cylinder 46 is vertically installed on a substrate 44 that is horizontally fixed inside the movable body 30 (on the left side in FIG. 3). This cylinder 46 is operated to move up and down in synchronization with the operation of the first cylinder 38, and an elevating support plate 50 is connected to the lower end of a rod 48 that hangs down from the lower surface of the base plate 44. The elevating support plate 50 is also connected and supported to the lower end of a guide rod 54 for steadying, which is vertically inserted into a shaft support 52 on the base plate 44 so as to be able to rise and fall freely, and the setting operation of the second cylinder 46 ( The rod 48 can be moved up and down with a stroke that matches the height of the work w. Note that before operation, the elevating support plate 50 is at a standby position for the movable body 30 and is stationary at a lowered position (see FIGS. 1 and 3). The first and second cylinders 38 and 46 are both hydraulically connected to a common control unit (not shown), and are operated in a predetermined order in synchronization with the operation of the conveyor 16. It is set.

A movable body 56 is attached to the lifting support plate 50 so as to be detachable and adjustable in position. In this movable body 56, an outer plate 60 having a substantially trapezoidal side surface is suspended and connected to one side of a horizontal support plate 58 fixed to the lower surface of the lifting support plate 50 via, for example, bolts or elongated holes.
The bed 12 is constructed in a frame shape (see FIG. 4), and due to the cooperation of the first and second cylinders 38 and 46, the bed 12 is moved in accordance with each movement of the movable body 30 and the elevating support plate 50. In the upper direction, a predetermined cycle movement is performed in the order of forward movement, upward movement, backward movement, and downward movement.

The leading member 64 is installed on the front side (left side in FIG. 1) of the movable body 56, and the holder 72 is installed on the rear side in alignment with the partition insertion line L corresponding to the stop position of the workpiece group W. There is. Leading member 6
4 moves forward while pushing aside the workpieces w to provide a predetermined distance between the workpieces w prior to insertion of the partition, and commonly functions as a "dew remover". This leading member 64 is
It is formed into a vertically long wedge shape that matches the height of the workpiece w, and can be attached/detached and its position adjusted via bolts and elongated holes, for example, with respect to the vertical support rod 62 that is suspended and fixed to the front surface of the side plate 60 of the moving body 56. is fixed. In order to allow the leading member 64 to proceed smoothly between the rows of workpieces, the guide member 64 is arranged in the feeding direction of the workpieces with reference to the entry ridge 66 that is aligned with the partition insertion line L as shown in FIG. A first guide surface 68 located at the front and a second guide surface 68 located at the rear.
The guide surfaces 70 of the guide surfaces 68 and 70 are formed obliquely in each direction, and the wedge effect of both guide surfaces 68 and 70 is used to allow the workpiece to quickly enter between the rows of workpieces. Note that the leading member 64 is connected to the insertion line L.
Before moving, the lower end of the workpiece w is held at a lower level than the flange f of the workpiece w, and in the process of moving straight along this level, the second guide surface 70 While pressing the workpieces w against the feed support rod 20, the workpieces w in the front row are aligned while being pushed forward (to the right in FIG. 3) using the first guide surface 68 to form a gap G ( (See Figure 7).

On the other hand, the holder 72 functions as a clamp or gripper for partitioning the moving body 56.
On each support shaft 74 protrudingly fixed to the rear surface of the side plate 60,
A pair of clamping pieces 76, 76 having a pad 78 are pivotally supported in a hanging state so as to be freely openable and closable, and both clamping pieces 76 are connected to each other by a gear 80.
As shown in FIG. 6, a connector 86 at the tip of a rod 84 of a cylinder 82 horizontally installed on the side plate 60 is articulated to the arm portion 76a of one of the clamping pieces 76.
Before the holder 72 is moved, it is on standby in the lowered position with both gripping pieces 76 expanded.
And the operation of the cylinder 82 (pushing of the rod 84)
When both clamping pieces 76 are closed, the upper part of the front end of the partition P fed from the partition supply section 88 is held between the pads 78 and held on the insertion line L.
Then, the lower ends of both clamping pieces 76 are held at a level appropriately higher than the upper surface of the workpiece w when the workpiece is moved.

The partition supply section 88 described above is arranged in parallel on the outside of the bed 12, and a large number of partitions P are housed in a hopper 90 on a conveyor (not shown) in a horizontally long and vertically upright state. There is. Then, by the intermittent feeding operation of the conveyor synchronized with the intermittent operation of the conveyor 16 (feeding timing of the workpiece group), the partition P is sequentially moved at a pitch of one sheet toward the feeding position facing the insertion line L. Sent out. Then, due to the operation of the feeding cylinder 92, the partition P at the forefront position is pushed back while being locked by the kicker 96 at the tip of the rod 94, and the workpiece group W
It is adapted to be fed to the holder 72 side in synchronization with the stop timing. Note that this supply section 8
Regarding No. 8, it is almost the same as the technology already practiced by the same applicant (the form disclosed in Japanese Patent Application No. 101664/1982), and it is also not the technical gist of the device in question, so it cannot be considered as above-mentioned. I'll stop at the explanation.

Effects of the Embodiment The partition automatic insertion device according to the present invention configured as described above is operated in synchronization with the workpiece feeding operation and the partition feeding operation, and is operated while each work group W is stopped. In this mode, the partition is horizontally pulled above the group of works and then released during the forward movement of the moving body 56 in a cyclical movement, so that the partition naturally falls and is inserted between the rows of works. I will explain in detail. That is, when inserting the partition, both the leading member 64 and the holder 72 provided on the movable body 56 are located at the starting end on the insertion line L. Therefore, in the holder 72, by the forward movement of the cylinder 82, both the clamping pieces 76,
76 closes and clamps the upper front end of the partition P that has already been fed from the partition supply section 88. By moving the first cylinder 38 forward in time with this, the movable body 30 on the frame 24 side moves toward the guide rod 28.
The movable body 56 is moved forward along the guide rail 36, and the movable body 56 together with the lifting support plate 50 is moved forward along the guide rail 36.
As the guide member 64 and the holder 72 are moved upward toward the other advancing end, the leading member 64 and the holder 72 move horizontally forward at a predetermined level relative to the stopped workpiece group W.

In this forward movement process, the leading member 64 enters between the front and rear work rows W' in the work group W in a wedge shape, as illustrated in FIG.
0 in sliding contact with each flange f, push the workpieces in the rear row to the feeding support rod 20, while pushing the workpieces in the front row smoothly forward in the feeding direction and align them, between both rows of workpieces (between the flanges f). The interval G for inserting the partition is formed to have a uniform width. On the other hand, the following holder 72 inserts the lower edge of the partition P into the above-mentioned interval G while moving at a predetermined level above the workpiece w, and holds the partition P at a level slightly lower than each flange f. Pull out P horizontally. When the movable body 56 and the movable body 30 are stopped at their respective forward ends, the leading member 64 is moved toward the bed 1, as shown in the imaginary line in FIG. 1 and in FIG.
2, and the holder 72 is located above the work w on the left end.

After that, the operations of opening the holder 72 and raising and retracting the movable body 56 are performed in order. That is, when the cylinder 82 is moved back (pulling operation), both the clamping pieces 76, 76 of the holder 72 are expanded, and the above-mentioned partition P is released. As a result, the partition P is quickly inserted into the interval G formed by the leading member 64 as described above in a free-falling state, and is held between the workpiece rows W' in a laterally elongated upright state. Note that when the holder 72 is opened,
The holding pieces 76, 76 do not interfere with each workpiece w at the left end. Then, as described above, when the partition P is released, the second cylinder 46 installed on the movable body 30 side is synchronously towed, and the movable body 56 is moved together with the elevating support plate 50. The guide member 64 and the released holder 72 are both raised to the rising end.

Subsequently, the first cylinder 38 is moved back, so that the movable body 30 is returned to its original position along the guide support rod 28 and the guide rail 36, and accordingly, the movable body 56 is moved together with the elevating support plate 50. Sending section 1
0 toward the rearward end. Accordingly, the leading member 64 and the holder 72 are attached to the bed 12.
Retreat so as to pass above. When the movable body 56 ascends or retreats, the feeding section 10 is driven again, and as the feeding conveyor 16 moves in pitch, the work group W into which the partition has been inserted is moved forward (right side in Figure 3). Next, the uninserted next work group W
are advanced by a pitch to a position aligned with the insertion line L, respectively. On the other hand, in the partition supply section 88, the next partition P is delivered to the delivery position.

Then, when the movable body 30 and the movable body 56 return to their respective retreat ends, the second cylinder 46 is moved back (downward operation), so that the movable body 56 is moved together with the elevating support plate 50. The leading member 64 and the holder 7 are lowered to the original position.
2 is returned to the starting end aligned with the partition insertion line L, and is waited at the same position for the next insertion operation. In this way, the partition insertion operation based on the cycle movement of the movable body 56 is completed, and from then on, as described above, by cooperation of the leading member 64 and the holder 72, the partition is inserted into the next workpiece group W of the feeding section 10. A horizontal pulling operation is performed, and a new partition P is quickly inserted into the interval G between the workpiece rows W'.

As described above, in this example apparatus, after the partition P is pulled out above the workpiece group W by the holder 72 following the leading member 64, the partition is released and inserted by gravity. Holding piece 7 when opened
Taking advantage of the fact that 6 and 76 do not interfere with the workpiece w, this method can be suitably applied to particularly small partitions, that is, partitions that are small in size compared to the height of the workpiece and the length of the row. This makes it possible to drop and insert such a partition between rows of workpieces properly and well. Furthermore, after inserting the partition P, both the leading member 64 and the holder 72 return above the feeding section 10, thereby preventing interference between these members 64, 72 and the group of works W on the bed 12. Since this is avoided, the pitch feeding of the workpiece, the leading member 64 and the holder 72 are avoided after the partition is inserted.
This makes it possible to return the partition at high speed, and the partition insertion operation can be made faster and smoother. In addition, since the leading member 64 can be adjusted up and down, the workpiece can have a different shape (flange f
Even if the size of the flange is different, or the position of the flange f is different up and down), or the weight is large,
Since it can be set to a level suitable for this, and under this condition, the interval G can be easily formed in the workpiece row W',
Its applicability is high.

Example of change Regarding the partition insertion device covered by this proposal,
The present invention is not limited to the techniques disclosed in the embodiments described above, and modifications and other forms may be proposed as appropriate. That is, the operating means of the movable body 56 may be replaced by the illustrated cylinders 38, 46, for example, a chain-like type on the first side, a crank or a link type on the second side, and for cyclic movement, a linear forward movement. (However, it may also be set in the order of diagonal forward movement accompanied by upward and downward displacement as appropriate) and circular backward movement including upward movement and downward movement. Further, the illustrated lifting support plate 50 and the movable body 56 may be formed integrally. The leading member 64 has a shape in which similar guide surfaces 68 and 70 are formed on both sides of the approach ridge 66, as illustrated in FIGS. 8a and 8b, and a first guide surface 68 on one side.
It may also be possible to make it replaceable according to the shape of the work, including those formed with a. As illustrated in FIGS. 9a and 9b, the holder 72 is a thin plate-shaped clamping piece 76 with an uneven clamping part formed on the lower edge, or a clamping piece 76 made of a wire rod bent into a channel shape. It may be configured. According to this, since the holder 72 itself can be made thin, it is possible to advance within the interval G. Regardless of the type, one of the clamping pieces 76 may be opened and closed, or it may be integrated with the leading member 64. In this case, the leading member 64 may be attached to the front of one of the clamping pieces. You may.

Furthermore, according to the partition insertion technique that is the object of the present invention, it is also possible to implement a direct horizontal insertion mode, which is different from the drop insertion mode of the above-described embodiment. In this embodiment, if the partition P is of a higher size than the workpiece w, or has a portion on its upper edge that protrudes appropriately from the upper surface of the workpiece, or even if it is of a smaller size than the workpiece w, the upper edge is appropriately raised above the upper surface of the bed 12. This can be suitably carried out when inserting the workpiece at a level protruding from the upper end surface of the workpiece. Further, as illustrated in FIG. 10, following the leading member 64 that advances between the work rows W' based on the cyclic movement of the moving body 56,
It is also possible to directly insert the partition P into the gap G by advancing above the work while the holder 72 is holding the upper front end or the center of the partition P.
According to this insertion example, even if the workpiece is relatively heavy, the leading member 64 can press against the workpiece W to form the gap G without overturning or deforming the workpiece W, and the subsequent holding Tool 72
can be inserted into the gap G without bending the partition P. Note that if the holder 72 of the type shown in FIGS. 9a and 9b is used, it is possible to insert even relatively small-sized partitions while moving within the interval G while being held by the holder 72. becomes.

Effects of the invention The partition insertion device of the present invention is capable of inserting a predetermined number of workpieces, which are intermittently fed one by one from the partition supply section outside the feeding section, during the pitch feeding process of a group of works that are boxed in units of multiple pieces. When inserting a partition horizontally, a movable support plate that is moved based on a predetermined cycle process is provided with, for example, a wedge-shaped leading member that can enter and pass through the group of works, and a guide member that holds and releases the partition. holding devices are installed in the transition order in accordance with the partition insertion line corresponding to the stop position of the workpiece group, and as the movable support moves forward, the leading member advances straight ahead and enters the workpiece group. However, the workpieces are pushed toward at least one side to form a suitable interval between the works, and in the process of subsequent advancement of the holder, the partition is pulled laterally and inserted into the above-mentioned interval appropriately.

In this way, by forming a space between the workpieces and inserting the partition well, it is possible to easily insert the partition between the workpieces. Furthermore, even if the workpiece is heavy, the partition can be inserted between the workpieces in its normal position without any difficulty. Further, according to this insertion mode, even if the partition is smaller than the workpiece, or has weak properties or material, it can be inserted well without losing the original protective function of the partition itself. Therefore, the applicability of the device itself is high.
