2. Description of the Related Art For example, in the field of cigarette pack packaging, a cigarette pack sent from a pack packaging machine is conveyed to a parcel packaging machine and packed by the parcel packaging machine in predetermined numbers. As is well known, pack packaging machines send out individual cigarette packs intermittently or randomly in a flat position, whereas parcel packaging machines pack cigarette packs stacked in a standing position. Therefore, in order to enable parcel packaging, it is necessary to change the transport position of the cigarette pack from the flat position to the upright position in the process of transporting the cigarette pack from the pack packaging machine to the parcel packaging machine. Between the pack wrapping machine and the parcel wrapping machine, there is provided a transfer posture changing device as disclosed in, for example, JP-A-62-285816 and JP-A-3-41712.

[0003] In the former device, the transport position is changed from the flat position to the upright position by dropping the cigarette pack in the flat position sent from the pack packaging machine into the drop guide, and thereafter, the lower end of the drop guide. The cigarette packs in the standing position are sequentially fed to a discharge conveyor. On the other hand, the latter device is provided with a vertical bucket conveyor instead of the above-described vertical guide, and the cigarette pack is sequentially fed into the bucket conveyor, thereby changing the transport posture of the cigarette pack from the flat posture to the standing posture. ing.

[0004]

In the former device described above, since the natural fall of the cigarette pack is used to change the position of the cigarette pack, there is a limit to speeding up the position changing process. In addition, each cigarette pack in the drop guide is discharged every time the lowest cigarette pack is discharged.
The drop is repeated, and as a result, the impact is repeatedly applied to the cigarette pack itself and the cigarette in the cigarette pack, and there is a possibility that these may be damaged.

On the other hand, in the case of the latter device, the impact on the cigarette pack can be reduced by employing a bucket conveyor. However, in order to feed the cigarette pack into the bucket conveyor, the feeding is synchronized with the running of the bucket conveyor. This is not suitable for speeding up the posture changing process. The present invention has been made based on the above circumstances, and the purpose thereof is to:
It is an object of the present invention to provide a device for changing the conveying posture of a product which can smoothly change its conveying posture without giving an impact to a product conveyed in a predetermined posture, and which is suitable for speeding up the posture changing process. .

[0006]

The above object has been achieved by the present invention, and the apparatus for changing the attitude of transferring a product according to the present invention (Claim 1) is provided with a constant speed conveyor on the upstream side. It receives a product that is intermittently supplied in a certain posture, and sends out the product at a constant speed. At the downstream of the constant-speed conveyor, a posture changing guide is connected in a horizontal direction.The posture changing guide accepts and guides the product from the constant-speed conveyor, and rotates the product by a predetermined angle in this guiding process. , Change the attitude of the product.

An acceleration conveyor is arranged downstream of the posture changing guide. The acceleration conveyor receives the product whose posture has been changed from the posture changing guide, accelerates the product, and intermittently receives the product whose posture has been changed from the outlet thereof.

A discharge conveyor extends from the vicinity of the exit of the acceleration conveyor in a direction crossing the acceleration conveyor, and the transfer posture changing device transfers the product between the acceleration conveyor and the discharge conveyor while maintaining the posture. And a delivery unit that performs the following.

According to the above-described conveying posture changing device, the product received by the constant speed conveyor is sent to the posture changing guide at a constant speed. In this posture change guide, the product is guided toward the acceleration conveyor in a so-called press-press state,
In this guiding process, the posture of each product is changed from, for example, the flat posture to the standing posture, and thereafter, the products are sent out to the acceleration conveyor. The product received by the acceleration conveyor is accelerated and separated from the product on the posture change guide side, and is intermittently sent out from the exit, and
The sheet is sent to the discharge conveyor by the transfer means, and is conveyed on the discharge conveyor.

Specifically, the above-mentioned posture changing guide is realized by a plurality of fixed guide rods extending between the constant speed conveyor and the acceleration conveyor and forming a torsion guide passage for products. ). In this case, the guide rod comes into line contact with the product, and guides the product smoothly. The delivery means includes a pusher that pushes the product delivered from the acceleration conveyor toward the discharge conveyor according to the delivery timing, and the pusher can reciprocate along a circular locus (claim 3). In this case, when the pusher returns, the pusher returns along a circular locus that escapes from the product delivered from the acceleration conveyor.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 schematically shows a transport posture changing device applied to, for example, a cigarette pack (hereinafter simply referred to as a pack). This transport attitude changing device includes a horizontal constant speed conveyor 2 at an upstream portion thereof, and the constant speed conveyor 2 is connected to a pack packaging machine via a connection conveyor 4. The pack packaging machine intermittently manufactures the pack P, and discharges the pack P onto the connection conveyor 4 in a flat posture with its surface facing upward. Therefore, the supply of the packs P from the connection conveyor 4 to the constant-speed conveyor 2 is intermittent. When the pack P is not continuously manufactured by the pack packaging machine, the supply of the pack P from the connection conveyor 4 to the constant-speed conveyor 2 is random.

Referring to FIG. 2, as can be seen more clearly, the constant speed conveyor 2 comprises a belt conveyor,
Is driven via the gear pulley 8 and the timing belt 10 and driven at a constant speed. Therefore, when the constant-speed conveyor 2 receives the pack P from the connection conveyor 4, the constant-speed conveyor 2 conveys the pack P at a constant speed and sends it out from the outlet.

Here, the processing speed of the constant speed conveyor 2 is slightly higher than the processing speed of the pack packaging machine,
When the pack P is transferred from the to the constant-speed conveyor 2, the pack P does not strongly collide with the preceding pack P on the constant-speed conveyor 2. Above the constant speed conveyor 2, a plurality of upper rollers 12 are provided.
Are arranged at predetermined intervals along the constant speed conveyor 2. More specifically, each upper roller 12 is supported by a plate-like holder 16 via a swing arm 14, and this holder 16 is suspended via a spring 18. The upper roller 12 prevents the pack P from jumping out of the constant-speed conveyor 2 and ensures feeding of the pack P to a posture changing guide section described later.

Side guides (not shown) are arranged on both sides of the constant-speed conveyor 2, and these side guides guide both sides of the pack P. The distance between the side guides can be adjusted according to the width of the pack P. An attitude changing guide section, that is, a small edge section 20 is connected to the outlet of the constant speed conveyor 2, and the small edge section 20 extends in the horizontal direction in the direction in which the pack P is sent from the constant speed conveyor 2. As shown in FIG. 2, the small edge section 20 includes an inlet frame 22 arranged near the outlet of the constant-speed conveyor 2 and a pack P from the inlet frame 22.
And an outlet frame 24 which is separated in the feeding direction. The inlet frame 22 and the outlet frame 24 are supported by a base 30 via a mounting base 26 and a pair of support legs 28.

From the entrance frame 22 to the exit frame 24, for example, six guide rods 32 extend. These guide rods 32 are made of round rods, and the end frames 22
And is fixed to the inner surface of the outlet frame 24. As is apparent from FIG. 2, each guide rod 32 is gradually twisted as it advances in the delivery direction of the pack P, and forms a torsion guide passage for the pack P in cooperation with each other.

More specifically, as shown in FIG. 3, the entrance frame 22 has a horizontal rectangular shape, and the six guide rods 32 have two ends at one end, two at the top and bottom, and one at the left and right. It is distributed and fixed to the entrance frame 22. One end of the guide rod 32 is horizontal to each other and forms an entrance portion of the torsion guide passage, and this entrance portion has a laterally rectangular shape so as to allow the pack P to be received in a flat posture.

Each guide rod 32 is twisted so as to be gradually displaced in the circumferential direction of the entrance frame 22, that is, the torsion guide passage from the entrance frame 22 to the exit frame 24, through the state shown in FIG. It reaches the exit frame 24. That is, FIGS.
In the middle, as shown by adding subscripts a to f to the respective guide rods 32, these guide rods 32 are twisted so as to be displaced clockwise in the circumferential direction of the torsion guide passage.

As is apparent from FIG. 5, the exit frame 24 has a rectangular shape in a vertical position, and the other six ends of the guide rods 32 are distributed one by one at the top and bottom and two at the left and right sides. 24. Each guide rod 3
The other end of 2 is also horizontal and forms an exit portion of the torsion guide passage, which exit portion has a vertical rectangular shape.

Further, as shown in FIG.
4, a pair of lower guides 34 and a pair of left and right side guides 36 are provided at the outlet of the torsion guide passage, respectively. These guides 34, 36 are each made of a plate material. The pair of lower guides 34 sandwich a guide rod 32 a located at the bottom of the exit frame 24, and
It is arranged flush with 2a. And the side guide 3
6 is between the guide rods 32 on the corresponding side, that is, between the guide rods 32b and 32c and the guide rods 32e and 32c.
The space between the side guides 36 corresponds to the thickness of the pack P. The pair of lower guides 34 and the pair of side guides 36 are fixed to a support frame 38 shown in FIG.
4 and is supported by a mount 26 of the outlet frame 24. 2, the side guide 36 protrudes toward the downstream side of the support frame 38, and enters the entrance of an acceleration conveyor 40 described later.

The small end section 20 receives the packs P sent from the constant-speed conveyor 2 in the torsion guide passage sequentially from its inlet, and packs P in the torsion guide passage to the succeeding packs P. While being extruded, it is guided in the twist guide passage and is transported toward its exit. That is, the transfer of the pack P is guided in the twist guide passage by the press-press method, and in this transfer process, as apparent from FIG. 1, the pack P is moved 90 degrees around the axis of the twist guide passage from the flat position. The transporting posture is changed to the twisted standing posture, that is, the small end standing posture.

When the pack P reaches the exit of the torsion guide passage, the pack P whose posture has been changed to the small end standing state is sandwiched between the left and right side guides 36 and the lower guide 2 is held.
4 and is delivered from its exit. Here, if the inside of the twist guide passage is in a steady state in which the pack P is filled, a slippage occurs between the constant-speed conveyor 2 and the pack P, and as shown in FIG. Above, the packs P are connected, and the sending speed of the packs P from the constant speed conveyor 2 matches the transfer speed of the packs P in the twist guide path. Therefore, the pack P is smoothly guided from the constant speed conveyor 2 into the twist guide passage, and the impact applied to the pack P is significantly reduced.

Further, in the twist guide passage, the pack P is continuously changed from the flat posture to the standing posture, that is, the small end standing posture, so that the posture changing process can be speeded up. Further, even if the supply of the pack P to the twist guide passage is random, the posture of the pack P in the twist guide passage can be changed, which is also suitable for speeding up the posture change processing. Becomes

By rotating the adjusting screw shaft 54 in the forward and reverse directions, the interval between the lower supports 48, that is, the interval between the side belts 42 can be adjusted according to the width dimension of the pack P.

Further, a bottom guide 56 is fixedly disposed between the side belts 42. This bottom guide 5
6 is connected to the lower guide 34 of the small edge section 20 at the same height level, and extends in a direction along the side belt 42. Downstream of the acceleration conveyor 40, a bottom conveyor 58 as a transfer section is arranged. The bottom conveyor 58 is also formed of a belt conveyor, and has a horizontal portion connected to the bottom guide 56 of the acceleration conveyor 40. The horizontal portion extends between the front and rear guide pulleys 60, and a drive pulley 62 and a tension pulley 64 are disposed below the horizontal portion. The bottom conveyor 58 is driven by the rotation of the driving pulley 62.

The both side belts 42 and the bottom conveyor 58 of the acceleration conveyor 40 described above share the common electric motor 6.
The electric motor 66 is driven by receiving the power of the motor 6, and is disposed below the acceleration conveyor 40 and is supported by the base 30 described above. The electric motor 66 has an output shaft, and a gear pulley 68 is attached to the output shaft. On the other hand, with respect to each side belt 42, the pulley shaft of the drive pulley 44 is connected to the universal joint shaft 70, these universal joints 70 extend downward, and the lower ends thereof are fixedly supported on the base 30. Gear pulleys 72 are respectively attached to the lower ends of the universal joint shafts 70, and these gear pulleys 72 are arranged in the same horizontal plane as the gear pulley 68. The universal joint shaft 70 allows the adjustment of the space between the side belts 42 described above.

Further, the driving pulley 6 of the bottom conveyor 58
2 is connected to a gear pulley 76 via a gear box 74, and this gear pulley 76 is also connected to a gear pulley 68,
72 are arranged in the same horizontal plane. An endless gear belt 78 is wrapped around the gear pulleys 68, 72, and 76, and the wrapping is apparent with reference to FIG.

When the electric motor 66 is driven, its power is simultaneously transmitted to the drive pulley 44 of each side belt 42 and the drive pulley 62 of the bottom conveyor 58, whereby the acceleration conveyor 40 and the bottom conveyor 58 are synchronized and Driven at the same speed. Here, the transport speed of the acceleration conveyor 40 and the bottom conveyor 58 is set to twice the transport speed of the constant speed conveyor 2.

When the pack P is sent from the small edge section 20 into the acceleration conveyor 40, the pack P is sandwiched between the side belts 42, and is accelerated by the side belts 42 toward the bottom conveyor 58. You. That is, as is apparent from FIG.
Separates the received packs P from the packs P in the small edge section 20 and conveys them intermittently and at high speed toward the bottom conveyor 58.

The pack P sent from the outlet of the acceleration conveyor 40 is received by the bottom conveyor 58 and is conveyed on the bottom conveyor 58. A stopper 80 is fixed directly above the bottom conveyor 58. The stopper 80 is located at a predetermined receiving position.
Stop the transport of In this case, the bottom conveyor 58 travels while sliding on the pack P at the receiving position. Note that the stopper 80 is movable in the axial direction of the bottom conveyor 58, and the receiving position thereof can be adjusted according to the length of the pack P.

Further, an upper guide 82 is disposed above the bottom conveyor 58, and the upper guide 82 extends to the outlet of the acceleration conveyor 40. Acceleration conveyor 40
The end of the upper guide 82 on the side is bent upward and
And it has a forked shape. Such an upper guide 82 stably guides the pack P sent from the acceleration conveyor 40 to the stopper 80.

The upper guide 82 is attached to a suspension plate 84 via a pair of vertically movable suspension rods 86. A coil spring 88 surrounding the suspension rod 86 controls the upper guide 82. It is urged downward. The suspension plate 84 is attached to the base 3 via the mounting member 90.
It is supported on the 0 side. Further, the suspension plate 84 is provided with a detent 94 via a bracket 92. A base end of the detent 94 is rotatably supported by the bracket 92, and is urged downward by a torsion coil spring (not shown). A lower end of the detent 94 is a forked end of the upper guide 82. It protrudes downward through the space between the parts.

The pack P sent from the acceleration conveyor 40
When the vehicle passes through the detent 94, the detent 94 is once flipped up and positioned on the rear side of the passed pack P. Therefore, even if the pack P comes into contact with the stopper 80, the detent 94 prevents the pack P from rebounding,
The pack P can be accurately positioned at the aforementioned receiving position.

As shown in FIGS. 8 and 9, a discharge passage 96 and a pusher mechanism 98 are respectively disposed on both left and right sides of the receiving position of the pack P. The discharge passage 96 extends from the bottom conveyor 58 in a direction orthogonal to the axial direction thereof. For example, a lower guide 100 located at the same height as the bottom conveyor 58, a pair of side guides 102 located on both sides of the lower guide 100, and an upper guide The passage 104 has a rectangular cross section. As shown in FIG. 8, the end of the upper guide 104 on the receiving position side is bent upward, and is suspended via a coil spring 106. In addition,
Spacing between side guides 102 and upper guide 104
Of course can be adjusted according to the size of the pack P.

Further, the discharge conveyor 1
08 is extended. The discharge conveyor 108 is a three-sided conveyor in which a bottom conveyor 110 composed of a belt conveyor and left and right side conveyors 112 are combined, and connects the discharge passage 96 and the barcel packing machine. Note that even in the discharge conveyor 108, the interval between the side conveyors 112 can be adjusted according to the length of the pack P. The discharge conveyor 108 has an independent drive source (not shown), and can be driven at a constant transport speed by this drive source.

On the other hand, the above-mentioned pusher mechanism 98 includes a pusher 114, and this pusher 114 is disposed on the opposite side of the discharge passage 96 with the above-described receiving position interposed therebetween. The pusher 114 is attached to one end of a mounting plate 116, and the mounting plate 116 extends horizontally on the side opposite to the discharge passage 96 side. The mounting plate 116 has a pair of egg-shaped crank arms 118.
Are mounted via eccentric pins 120, and the crank arms 118 are spaced apart in the longitudinal direction of the mounting plate 116.

The pair of crank arms 118 are connected to gear pulleys 128 and 129, respectively. Of these gear pulleys, the gear pulley 128 on the pusher 114 side is attached to the output shaft 124 of the servomotor 122, and the other gear pulley 129 is Bearing (not shown)
Is rotatably attached to the support shaft 126 via the. The servomotor 122 is supported by the base 30, and the support shaft 126 is erected on the base 30.

A gear pulley 130 (see FIG. 9) functioning as a toner is disposed near the gear pulley 128. The gear pulley 130 is rotatably supported on the base 30 side. Gear pulleys 128 and 12 described above
An endless timing belt 132 is wrapped around 9, 130 so that the pair of crank arms 118 can rotate in one direction in synchronization with the driving of the servomotor 122. The rotation of these crank arms 118 causes the pusher 114 to reciprocate along a circular locus via the mounting plate 116, whereby the pusher 114
Can advance across the bottom conveyer 58 into the discharge passage 96, and can then return from within the discharge passage 96 across the bottom conveyer 58. Here, the direction of the reciprocating movement of the pusher 114, that is, the direction of the circular movement is set to the direction in which the pusher 114 moves backward while being displaced in the conveying direction of the bottom conveyor 58 as shown in FIG. I have.

When the pack P arrives at the above-mentioned receiving position and is received, and the reciprocation of the pusher 114 is performed, the pack P is pushed into the discharge passage 96 from above the bottom conveyor 58 by the pusher 114. In order to determine the reciprocating timing of such a pusher 114, an arrival sensor for optically detecting the arrival of the pack P above the bottom conveyor 58 at the receiving position as shown in FIGS. 134, the servo motor 122 receives the arrival signal from the arrival sensor 134, that is, the timing at which the pack P is sent out.
It is driven by one reciprocating stroke of 14.

When the reciprocation of the pusher 114 is controlled in this manner, even if the pack P arrives at the receiving position at random, that is, even if there is a deviation in the arrival interval of the pack P to the receiving position. Thus, the pack P can be reliably pushed into the discharge passage 96. Further, as shown in FIG. 1, a passage detection sensor 136 that optically detects the passage of the pack P at a predetermined interval above the acceleration conveyor 40.
Are disposed above the discharge passage 96, and a passage detection sensor 138 similar to the passage detection sensor 136 is disposed at a predetermined interval.

The passage detection sensor 136 is connected to the acceleration conveyor 4
The passing signal of the pack P from 0 is detected, and the driving of the acceleration conveyor 40 is controlled based on the passing signal and the arrival signal. That is, continuous entry of the pack P to the receiving position is prevented. Therefore, as a result of the pack P being intermittently supplied to the receiving position, the pusher 114 can reliably push the packs P one by one into the discharge passage 96.

As described above, when the pusher 114 returns,
Since the pusher 114 returns so as to escape from the next pack P that advances toward the receiving position, the pusher 11
There is room for 4 reciprocations. As a result, even if the interval at which the pack P reaches the receiving position is short, that is, even if the process of changing the attitude of the pack P is accelerated, the pusher 114 can reliably push the pack P from the receiving position into the discharge passage 96. Can be.

As is apparent from FIG. 1, each time the packs P are sequentially pushed in the discharge passage 96, the packs P are transferred to the discharge conveyor 108 in a press-and-press manner, and
When the leading pack P reaches the discharge conveyor 108, it is conveyed on the discharge conveyor 108 at a constant speed toward the parcel packaging machine. The passage detection sensor 138 disposed above the discharge passage 96 is used for confirming the pushing of the pack P by the pusher 114, counting the number of the packs P, and the like.

The present invention is not limited to the above-described embodiment, and various modifications are possible. For example, the guide rod 32 of the small edge section 20 is not limited to a round bar, but may be a plate shape, and the number thereof is not limited to six. Further, the discharge conveyor 108 with the acceleration conveyor 40
Even if there is a means to transfer the pack P between
The present invention is not limited to the illustrated one, and can be appropriately changed.
