Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a conveying device for a paper cup, and more specifically, the present invention relates to a conveying device for a paper cup, and more specifically, the present invention relates to an apparatus for conveying a paper cup, and more specifically, it is an apparatus for conveying a paper cup. The present invention relates to a paper cup conveying device. Here, the term "paper cup" refers to a cup made of paper or a material with similar properties to paper, and includes a cup whose surface has been coated.

Paper cups are commonly used as containers for vending machines and are widely used as containers for various foods. In these applications, if there are insects, hair, oil, etc. attached to the inside of the container, it goes without saying that the container cannot be used as a food container, but even if there is generally harmless material such as chip residue, it may be objectionable to use the container. There is a tendency. There is a high demand for inspecting the inner surface of such rolled paper cups, and visual inspections have been carried out by humans as necessary. Experienced people have a high degree of freedom in judgment, and even when there are a wide variety of test items, 1. Although it is superior in terms of processing time, accuracy, and economy, on the other hand, it varies from person to person, is easily influenced by preconceptions, is easily influenced by the mood of the moment, and although it does not overlook stains due to fatigue. However, there are drawbacks such as the inability to continue building shelves at a constant pace for long periods of time. Therefore, automation of testing has been desired. This is because if automatic inspection equipment can be used in place of human visual inspection, it will be possible to ensure a certain level of accuracy and objectivity in the inspection results, and at the same time it will save labor and enable long-term continuous operation. can.

For an automatic paper cup inspection device, a conveying device is required to convey the paper cup and position it at an inspection position.

Therefore, if we consider the conveyance device, we will consider the 41 Kaisho 5O-- which is used in an automatic glass bottle inspection device that detects scattered light from scratches by emitting radar light while rotating the % Plus bottle at the inspection position. The rotary table type conveyor device that comes to mind is the one disclosed in S Kuko No. 91 newsletter, and this rotary table Wi conveyor device has a female screw and star wheel that sends bottles to the rotary chute, and a rotary table KO.
It is equipped with a friction belt to rotate the placed bottles, but all of them are designed to contact the bottles with a gentle force. However, paper cups have lower mechanical strength than glass bottles, and if they are contacted with such an axial force, they will deform and, in extreme cases, break. On the other hand, when inspecting the inner surface of a paper cup with a fixed surface detection device, the paper cup must always be placed in a fixed position, and there is only one automatic inspection device. If so, it is necessary to rotate the paper cup at that fixed position. However, the conveying device for glass bottles as described above rotates by rubbing the side of the bottle with a friction belt, which causes the paper cup to be deformed, expanded and crushed, and even if the paper cup is not deformed, the paper cup is The tapered surface is raised and the center axis is greatly tilted. If the paper cup is thus deformed, raised, or has a greatly inclined central axis, the surface of the paper cup cannot be accurately compared with the inspection/turn.

As described above, the conventional conveying device cannot meet the special characteristics of paper cups, and cannot be used for paper cups at all.

Furthermore, in the method of rotating the paper cup when it reaches the inspection stage, it takes time for the paper cup to rotate at a predetermined speed. However, in order to speed up the surface inspection of the paper cup, it is preferable that the time required for this acceleration be as short as possible.Therefore, a method of pre-acceleration may be considered, but the conventional method would complicate the structure and is not preferable. do not have.

Therefore, an object of the present invention is to provide a conveyance device that can accurately position a paper cup at an inspection position without deforming it, and that can rotate at a constant speed at the inspection position without requiring acceleration time. It is something to do.

Furthermore, it is an object of the present invention to
It is an object of the present invention to provide a conveying device that can reliably cut paper without deforming the paper or causing eccentricity or lifting.

That is, according to the present invention, there is provided a rotary indexing table that is driven intermittently, and a rotary indexing table that is disposed around the indexing table and is supported so as to be able to rotate relative to the indexing table, and that tightly receives the lower part of the paper cup. a cup holder having a concave portion; a sun gear that is rotatably and coaxially mounted on the rotation axis of the index table and is continuously driven; There is provided a paper cup conveying device comprising a playback vehicle that fits together, a supply means for supplying a paper cup to the cup holder, and a discharge means for discharging the paper cup held in the cup holder from the mosquito cup holder. .

Since the paper cup is held by the cup holder, which has a concave portion extending from the bottom of the paper cup, there is no need to apply strong external force to the paper cup to deform it. You can rotate it there.

At that time, the paper cup does not float or become eccentric with respect to the axis of rotation.

Further, the rotation of the indexing table causes the paper cup held in the cup holder to revolve together with the indexing table and be positioned at the inspection station, and the continuous rotation of the sun gear causes the paper cup to be positioned at the inspection station via the planetary gears. Since it is configured to rotate at a constant speed independently of the rotation of the indexing table, there is no need for acceleration time for the rotation of the paper cup at the inspection position, and high-speed processing is possible.

In one embodiment of the conveying device according to the present invention,
A hole communicating with the hollow chamber of the rotating shaft is formed at the bottom of the cup holder, and the hollow chamber of the rotating shaft is communicated with a vacuum source to ensure that the paper cup is suctioned and held in the cup holder. ing. Further, a pushing mechanism is provided for pushing the paper cup received in the cup holder into the mosquito cup holder and positioning it appropriately. This paper cup pushing mechanism is constructed to include a piston cylinder device and a pushing disk that is driven up and down by the cough piston cylinder device.

In a preferred embodiment of the transport device according to the invention, the indexing table is provided with at least a supply station, a test stay S/Ron and a discharge station around the indexing table;
The supply means is provided at the supply stage, and has a hole formed in the bottom of the cup holder, and has a communication shaft in the rotation axis of the cup holder that communicates with the hole in the bottom of the cup holder and extends in a radial direction. a hollow chamber having a hole is formed, and a spacer member is fixed to the index tape A/ that rotatably holds the rotation axis of the cup holder and has an annular chamber channel surrounding the radial hole; Furthermore, a seventh annular member having a hole communicating with the annular channel is fixed to the revolution axis of the indexing table, and the seventh annular member is configured to selectively communicate with the hole of the seventh annular member. A second annular member, in which a hollow chamber is formed that is open to the annular member 7 and extends in the circumferential direction, rotatably receives the revolution axis and is fixedly supported at the 7 part of the device. The hollow chamber of the annular member extends in the local direction to accommodate the supply station and the inspection station, and extends circumferentially to accommodate the vacuum chamber connected to the vacuum source and the discharge station. The paper cup is separated into a high-pressure chamber connected to a pressure source, and when it is supplied to the cup holder in supply stage 1, it is suction-held by the cup holder and continues to be suction-held until the inspection station, and then to the discharge station. The cup is lined up so that it will be released from the holder when it reaches. By doing this, the paper cup can be reliably held by suction and can be reliably ejected at the ejection station. In addition, a push-in stage seal is installed at the junction between the supply station and the inspection station, making it very cool! A pushing mechanism for pushing the paper cup suction-held onto the holder into the cup holder and appropriately positioning the paper cup may be provided therein to more reliably position the paper cup within the cup holder.

Further, the discharge station is divided into a defective product #exit stage and a good product delivery station, and the high pressure chamber of the first annular member is expanded in the circumferential direction so as to correspond to the defective product discharge stage 1. The pressure source KJI was connected through the first valve and spread in the circumferential direction so as to correspond to the high pressure chamber 1 and the quality goods delivery station, and was connected to the pressure source through the 9th valve. The paper cup may be separated into vibrations by separately opening the first valve and the λ-th valve separately from the a-th high-pressure chamber.

Embodiments of the conveying device according to the present invention will be described below with reference to the accompanying drawings, and FIG. 7 is a perspective view of an automatic inner surface inspection device for paper cups incorporating the conveying device according to the present invention.

This automatic surface inspection device includes a conveyance device 10 according to the present invention that receives a paper cup, conveys it to an inspection position, and rotates there, and a conveyance device 10 according to the present invention that detects the inner surface of the paper cup and transmits the detection data to M
IIL, the detection processing device 12 that determines pass/fail is the true value. The detection processing device 12 includes a surface detection device 14 that detects the inner surface of the paper cup;
Although the present invention is not directly related to the present invention, a description thereof will be omitted since it is not directly related to the present invention.

The conveying device 10 is shown in FIGS. FIG. 2 is a top view of the transport device lO], and the third rI! J is a sectional view taken along line 2--2 in FIG. 2, and JyS is a sectional view taken along line mV--2 in FIG.

As can be seen from the figure, the third factor and the third factor are that the paper cutter 10 has an inner shape of the same shape and size than the outer shape of the paper cutter f200.
The cup holder 22 has a cup holder 22 having an IS, and the cup holder 22 has a height that allows the paper cup to be held in a concave manner without causing the paper cup to shift, for example, a height that can accommodate at least the lower half of the paper cup. It is preferable. If this cup holder 22 holds a paper cup, the paper cup can be rotated once by rotating the cup holder 22. Furthermore, since the concave part of the cup holder 22 has the same shape and dimensions as the outer shape of the paper cup, the center of the cup holder can be accurately aligned with the central axis of the paper cup, and the paper cup can be rotated around the central axis. It can be rotated.

For example, six bonito holes 22 are arranged at equal angular intervals around the circular indexing table 240, as shown in the first @. The indexing table 24 is fixed to a rotating shaft 28 rotatably supported by a frame 26 of the conveying device 10. Six pieces 30 are fixed around the indexing table 24 at intervals of 60 degrees, and a rotating shaft 34 is rotatably supported on the pieces 30 via bearings 32.

A flange 36 is formed on the upper end of the rotation shaft 34, and a cup holder 22 is attached to the 7 flange 36 with a screw 38.
It is fixed in place. Therefore, the cutlet holder z2 can be replaced according to the size and shape of the paper cup.

9. The cup holder 22 has an index table of 240 laps.
! It is possible to rotate at .

In Fig. 2, ■ is a supply station, ■ is a pushing station for firmly pushing the paper cup into the cup holder, I is an inspection station, and p1 is a preliminary station. (■) is a defective product discharge station), (■) is a feeding stage. Therefore, due to the intermittent rotation of the indexing table, the inspection table was reached and the ninth cup hole was reached at 22, as described above. ! Since the surface detection device is of a scanning type, it is necessary to rotate it there. On the other hand, for high-speed inspection, the time from when the cup holder 22 rotates on its own axis until it reaches constant speed rotation at the inspection station must be minimized as much as possible. A method of accelerating the cup holder by giving it rotation in advance at the previous station is conceivable. One of the ways to do this is to use the Cag Hole/22 7
Lunge 40 circumference Kjl! The seven stays S in front of the inspection station are similar to friction wheels that rotate in frictional contact.
It is also possible to install it in /con. However, such a method is undesirable because the friction portion is worn out, requiring frequent replacement of the friction wheel, and the structure is complicated.

Therefore, in this embodiment, the planetary gear 42 is attached to the cup holder, and the planetary gear 42 is rotated by the nine-sun gear 44 in a positional relationship as shown in FIG. That is,
As shown in FIG.
It is attached to the rotating shaft 28 via a bearing 46. A gear 48 rotating K11 together with the sun gear 44 is also attached to the rotating shaft 28 via a bearing 46, so that the sun gear 44 and the gear 48 can freely rotate with respect to the rotating shaft 2B, that is, It is made to rotate independently from the rotating shaft 28. The gear 48 is aligned with a gear 52 which is rotatably supported by the frame 26 and has a rotating shaft of 50 km.

Thus, when the rotating shaft 50 rotates, the gears 52 and 48
The sun gear 44 rotates independently of the rotating shaft S8 via the rotation shaft S8, and the cutter hole rotates via the idler gear 42.

In this way, if the sun gear is rotated at a constant speed, the planetary gear 42, that is, the cup holder 22, will rotate at a constant speed even during the intermittent rotation of the index table 24. When it comes to rest, it rotates at the same constant speed based on its stage behavior. Note that when the direction and rotational speed of the intermittent rotation of the indexing table 24 are the same as the direction and rotational speed of the sun gear 440, the planetary gear 42, that is, the cup holder 22, is rotated by the indexing table when the indexing table rotates. Although it does not rotate relative to the stage, it still rotates at a constant speed, and when the indexing table comes to rest, the stage blades rotate at the same constant speed. Thus, no acceleration time is required for the rotation of the cup holder.
High-speed inspection becomes possible.

In such a conveying device, it is necessary to rotate the cuffing wheel at least 47 times or more during the period when the indexing table is stationary. For this purpose, a method is usually used in which the rotation of the index table and the rotation of the cup holder have a certain relationship. One way to do this is to drive the rotary shafts 28 and 50 from the same drive source through gears with an appropriate gear ratio so that the cag hole always rotates seven times - during the period when the indexing table is stationary. . According to this method, the number of drive sources can be reduced, and the mutual operational relationship between the indexing table and the cup holder can be determined accurately based on the gear ratio, which is convenient.

However, when considering adjustment of the dirt detection sensitivity of the detection processing device 12 and other maintenance, it is preferable to be able to rotate the cup holder at the same speed as during actual inspection while keeping the index table stationary.

Therefore, in the illustrated embodiment, the rotating shaft 2B is an intermittent drive ninth cam index mechanism 53a1 drive shaft 53.
It is connected to an AC motor S3 through a speed reduction mechanism S3c of the b1 variable ratio plate and a belt 53d, and the rotating shaft 50 is connected to a DC motor s4b for continuous rotation through a reduction gear 54.

However, by using the same drive source to drive the rotating shaft 5o through a gear and driving the rotating shaft 28 through another gear and clutch, it is possible to allow only the cup holder to rotate continuously (by releasing the clutch). You can also do this.

At the top of the supply stage cylinder 1, there is a paper cup accumulation cylinder 56.
is located. At the bottom of the paper cup accumulating cylinder 56, two sets of cup feeding screws 58 are provided, which are synchronously rotated by a shaft 6D, a sedge rocket 62 and a chain 64. Further, the shaft 60 of one cup supply screw has a sprocket 66, a chain 68,
It is driven via a sprocket 70 and shaft 72 by a motor 74 which is driven in synchronization with the movement of the index table. Thus, the cup feeding screw 58 is rotated synchronously by the operation of the motor 74, and the upper 1117 run section (indicated by reference numeral 76 in the TTWA) of the paper cup in the paper cup accumulating cylinder 56 is wound into the valley part of the screw. At the same time, each paper cup is separated one by one and fed onto a cup holder which is stopped at feeding stage day l.

In order to ensure that the paper cup fed to the cup holder by the lug supply stage 58 is properly placed and retained within the cup holder, in the illustrated embodiment, the paper cup is vacuum-suctioned on the cup holder side. For this purpose, a hole 78 is formed at the bottom of the cup hole 22, and a 9th part 80 is formed at the central axis of the rotation shaft 34 so as to communicate with the hole 78, and radially extends from the hollow part 80. Punishment hole 8
2 is formed. An ell-shaped channel 84 is formed in the gas 30 so as to surround the holes 82, and one end of a hose 86 is connected to the annular channel 1I4. The other end of the hose 86 is connected to holes 110 formed at equal angular intervals toL in the horizontal member 88, which has a co-rotating axis 28KII. Confucian Elf facing the hole 90
The released hollow mold is formed / /)0* shaped member 92
are attached to the rotating shaft 28 via a bearing 94 and layered. ζO
The II-shaped member 92 has a frame of 26 km and nine arms 9.
The tip K111 of the horizontal arm section 6 is fixed. As shown in FIG. 4, the hollow mold of the annular member 92 is designed to correspond to the supply stage 1zyl, the pushing stage 1, the inspection stage 1, and the preliminary JP-1 stage. True that spreads circumferentially! 2898, a first high pressure block 100 located at a position corresponding to the defective product discharge stage V, and a high pressure block 102 located at a position corresponding to the discharge stage V. The vacuum 1198 is connected to a vacuum source (not shown) via a hose 104, the high pressure generator 100 is connected to a compressed air source (not shown) via a hose 106 and a solenoid valve 108, and a first The high pressure chamber 102 is similarly connected to a compressed air source (not shown) K via a hose 109 and a solenoid valve 110.

Thus, even when the rotation shaft 34 is rotating, the hollow part 80 of the rotation shaft 34 communicates with the annular channel 84 through the hole 82, and the hose 86 is connected to the hole in the nine-shaped member 88. 90 communicates with the vacuum 119g and either of the first and first high pressure chambers 10G and 102 according to the rotation of the index table. Therefore, when the cup holder is in transit from the supply station (2) to the reserve station (2), a negative pressure is created in the cup holder via the hole 78.

Therefore, at the feeding station I, the paper cup fed from the cup feeding screw 58 is sucked into the cup holder to ensure that it is received and retained at least until the reject discharge station.

As such, the paper cup that has entered cup holder #3 is pushed into the cup holder by four pushers $112 in the next pushing stage. This is for, when the paper cup f is not held in close contact with the cup holder, to position the paper cup in the cup holder correctly and bring it into close contact by pushing the paper cup. Therefore, if the paper cup can be properly positioned and brought into close contact with the cup holder by vacuum suction, there is no need for a pushing mechanism.On the other hand, the feeding station can simply drop the paper cup without using vacuum suction, and the pushing station can The paper cup may also be pushed in to hold it in place.

This pushing mechanism 112, for example, as shown in FIG.
It can be constructed by fixing a triangular plate 118 to a piston rod 116 of a piston cylinder device contained in a case 114, and fixing a shaft 122 having a push-in disk 12G and a tip marked *b at its apex.

The remaining two points of the triangle Ijl18 are the upper 7 points of the case 114.
It is slidably supported by a guide rod 126 fixed to a twister 124. Therefore, by operating the piston-cylinder device, the pushing disk moves up and down to ensure that the paper cup in the cup holder is pushed all the way to the bottom of the cup holder so that it is held in tight contact.

The paper cup that has passed through the push-in station is inspected blindly at the inspection stage, and further passes through the preliminary station (2) and reaches the defective product discharge station V. If the paper cup is determined to be defective as a result of the inspection, the solenoid valve 108 is activated. It is opened and compressed air is introduced into the bottom of the cup holder/22 through the first high pressure 1g1oo, so that the paper cup is ejected from the cup holder 22 and discharged through the reject outlet, 128. If the paper cup is determined to be good as a result of the inspection, it passes through the defective product discharge stage V.
Reach the sending station■. The solenoid valve 110, which is energized every time the table is inactive, is then opened and the cup holder 22 is opened via the first high pressure chamber 102.
Compressed air is introduced at the bottom of the cup and the paper cup is delivered from the cup holder 22 through the delivery duct 130.

As described above, the above-described embodiment of the conveying device according to the present invention can accurately position the paper cup at the inspection position without deforming it. ) and without requiring acceleration time, it can be rotated at constant speed.
