The seal lid supply device 10 is a device that can supply the lid to the opening of the cup 4 conveyed by the conveyor device 1 while inverting the seal lid 18 supplied from the magazine 17.
[0025]
A reversing cam 22 is pivotally attached to a vertically moving arm 21 that can move vertically via a rack 19 and a pinion jar 20. A trifurcated groove cam surface 23 is provided on the side surface of the reversing cam 22. A plurality of vacuum pads 25 are attached to the reversing cam 22 via suction pipes 24, and the sealing lid 18 can be sucked and held by the suction surface 25 a of the vacuum pad 25.
[0026]
The vertical movement arm 21 is configured to be intermittently moved up and down by two vertical cylinders 26 and 27. Reference numeral 28 denotes a vertical movement shaft, which is configured so that the vertical movement arm 21 can move up and down along this axis. A vacuum device (not shown) is connected to the suction pipe 24, and is configured to be sucked from the suction surface 25a of a vacuum pad 25 attached to the suction pipe 24.
[0027]
In the figure, reference numeral 29 denotes a cam follower, which is constituted by three bearings 29a attached at predetermined positions of the frame 30 with a predetermined interval, and meshes with the trifurcated groove cam surface 23 of the reversing cam 22. Thus, the reversing cam 22 can be rotated. Stop plates 31 are respectively attached to the upper and lower sides of the frame 30 so that the reversing cam 22 can be stopped at an accurate position when it reaches the top dead center or the bottom dead center.
[0028]
The seal lid dust removing device 11 is disposed close to the side of the seal lid supply device 10. Reference numeral 32 denotes a horizontally arranged vacuum box, the tip of which is partially opened, particularly as shown in FIG. 8, and is attached to a slide shaft 34 supported by a slide metal 33. It is configured to be able to slide back and forth. A falling dust collector 35 is attached to the lower part of the vacuum box 32.
[0029]
The relationship between the seal lid supply device 10 and the seal lid dust removal device 11 is as follows, particularly when the vacuum pad 25 of the seal lid supply device 10 is turned sideways as shown in FIGS. The adsorbing seal lid 18 faces the tip of the vacuum box 32 of the seal lid dust remover 11, and the tip of the vacuum box 32 slides toward the seal lid 18 together with the slide shaft 34 so that they are close to each other. It is configured so that it can be made.
[0030]
In this vacuum box 32, two discharge electrodes 36 capable of discharging static electricity from foreign matters such as dust adhering to the seal lid 18 are arranged vertically in parallel at a predetermined interval. An air ejection nozzle 37 is provided horizontally between these parallel discharge electrodes 36.
[0031]
A pipe 38 for blowing clean air is connected to the air ejection nozzle 37 so that air can be ejected to the seal lid 18 adjacent to the tip of the vacuum box 32. As shown in FIGS. 5 and 8, the pipe 38 is provided with a connection port 39a connected to a clean air supply source 39 capable of supplying clean air. Further, a suction duct 40 connected to a vacuum blower 41 is attached to the vacuum box 32.
[0032]
A pipe 38 capable of supplying clean air to the air ejection nozzle 37 is disposed over the entire length of the vacuum box 32 in parallel with the discharge electrode 36 as shown in FIG. The number of air ejection nozzles 37 attached to the pipe 38 is the same as the number of seal lids 18 arranged in parallel in the width direction of the seal lid supply device 10. It is configured to be able to eject clean air.
[0033]
The static eliminator using the above-described discharge electrode 36 used in the present invention neutralizes excess charges with reverse polarity charges, that is, supplies negative charges to those that are positively charged, and negatively charges them. Is a static eliminator that neutralizes charged charges by supplying positive charges. There are three types of static eliminators depending on the ion generation method: voltage application type static eliminator, self-discharge type static eliminator, and radiation type static eliminator. Electric appliance is effective.
[0034]
The former voltage application type static eliminator is composed of a static elimination electrode, a high-voltage electric wire, and a high-voltage power source, and is a system in which a high voltage is applied to a discharge needle installed on the static elimination electrode to generate ions necessary for static elimination. That is, a corona discharge is generated from a discharge needle to which a high voltage is applied, and a device that applies high voltage discharge in which ions are generated therein, a so-called corona discharge type static eliminator.
[0035]
The latter self-discharge type static eliminator is a static eliminator that does not require a high-voltage power supply, and uses the electrostatic energy of a charged object. That is, when a grounded needle electrode (static eliminator) is directed to a charged object, an unequal electric field is formed between the charged object and the needle electrode, and as a result, gas molecules in the vicinity of the needle electrode where the electric field strength is increased This is an apparatus of a type in which positive and negative ion pairs are generated by ionization by the electrical energy of the electrodes.
[0036]
Examples of the discharge electrode 36 used in the static eliminator include a BU type, a BUY type using a spring type discharge needle, a BIC type using a needle type discharge needle, a BHC type, and a general discharge electrode. A BB type in which the needle and the ground electrode are insulated by air can be used effectively.
[0037]
The operating state of the seal lid supply device and the seal lid dust removal device according to the present invention will be described in detail as follows. That is, first, the seal lid supply device 10 will be described. Specifically, as shown in FIGS. 6, 7, 9A, 9B, 9C, when the vertically moving arm 21 reaches the top dead center. The vacuum pad 25 faces upward and the lowermost seal lid 18 stacked on the magazine 17 is sucked and held by the suction surface 25a.
[0038]
Next, when one of the vertically moving cylinders 26 is actuated to start the descending of the vertically moving arm 21, the trifurcated groove cam surface 23 of the reversing cam 22 attached to the vertically moving arm 21 is fixed to the frame 30. When the vacuum pad 25 fixed to the reversing cam 22 via the suction pipe 24 faces sideways, that is, the cam follower 29 including the three bearings 29a is rotated one after another. It stops when the seal lid 18 adsorbed by the vacuum pad 25 faces the tip of the vacuum box 32 of the seal lid dust remover 11. In this state, the seal lid dust removing device 11 performs dust removal work of the seal lid 18 described later.
[0039]
Immediately after the dust removal of the seal lid 18 is completed, if the other vertical movement cylinder 27 is actuated to lower the vertical movement arm 21, the trifurcated groove cam surface 23 of the reversing cam 22 comes into contact with the cam follower 29. The reversing cam 22 is gradually rotated so that the suction surface 25a of the vacuum pad 25 faces downward, and the seal lid 18 sucked and held on the suction surface 25a can be supplied to the cup 4 conveyed by the conveyor device 1. Thereafter, by raising the vertical movement arm 21, the vacuum pad 25 can be further rotated while preparing for the next suction and holding of the seal lid 18.
[0040]
Next, the operation of the seal lid dust removing device 11 will be described. When the above-described vacuum pad 25 is turned sideways and temporarily stopped, the vacuum box 32 is moved forward, and its tip is adsorbed by the vacuum pad 25. The seal lid 18 can be brought close to the holding.
[0041]
In this state, the two discharge electrodes 36 disposed in the vacuum box 32 are operated to completely remove the foreign matter such as dust adhering to the seal lid 18 and the seal lid 18, and at the same time clean from the air ejection nozzle 37. The foreign matter can be peeled off from the seal lid 18 by ejecting air. On the other hand, since the vacuum box 32 is always sucked by the duct 40, the foreign matter peeled from the seal lid 18 can be sucked into the vacuum box 32 and processed.
[0042]
Therefore, it is possible to completely remove dust from the hair and resin fine powder, which have been difficult to completely remove from the seal lid 18 in the past, and to completely collect dust. The seal lid 18 thus processed is supplied to the cup 4 conveyed by the conveyor device 1 and can be covered with the opening of the cup 4. Further, the foreign matter dropped during the dust removal operation can be processed by being sucked into the vacuum box 32 after being received by the falling dust collector 35. For this reason, there is no concern that foreign matters that fall during the dust removal operation will enter the cup 4 that is already filled with food such as ice cream.
[0043]

Since the cam follower that can reverse the cam and the vacuum pad is arranged at a predetermined position, the seal lid supplied from the magazine is reversed while being sucked by the vacuum pad and supplied onto the cup conveyed by the conveyor device. Has the effect of
[0044]
In the present invention, when a trifurcated groove cam surface is formed on the reversing cam used in the first invention and the cam follower corresponding to this is constituted by three bearings, The reversing cam can be rotated at a predetermined timing by engaging and combining the trifurcated groove cam surface with the three bearings. Therefore, the vacuum pad fixed to the reversing cam can also be rotated simultaneously with the reversing cam.
[0045]
In the present invention, when the three-way groove cam surface of the reversing cam and the three bearings of the cam follower are combined at a predetermined timing, when the vertical movement arm reaches the top dead center, The suction surface of the vacuum pad fixed to the reversing cam is directed upward. When the vertical movement arm is lowered halfway, the suction surface of the vacuum pad is directed to the side, and the vertical movement arm is further dead. When the point is reached, the suction surface of the vacuum pad can be directed downward, thereby having the effect of reversing the seal lid held by suction on the suction surface.
[0046]

Can be brought close to the supplied seal lid while being inverted by the seal lid supply device.
[0047]
In addition, since the air ejection nozzle and the discharge electrode are respectively disposed in the vacuum box, the foreign object adhered to the seal lid by the air ejection nozzle while discharging the foreign matter such as dust adhered to the seal lid by the removal electrode. There is also an effect that the foreign matter adhered to the seal lid can be completely removed by peeling and diffusing, and sucking the diffused foreign matter with a vacuum device.
